                              DESCRIPTION OF NOTES
 
GENERAL
 
    The Notes offered hereby will be issued under the Indenture dated as of
        , 1998, as supplemented from time to time (the "Indenture"), between the
Company and Bank One, N.A., 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 $65,000,000 subject to
reduction in the event of sales of Common Stock 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 ("Holders") 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 additional 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.
 
    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
 
                                       4
<PAGE>
    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, as agent for the
    Trustee, 14 Wall Street, 8th Floor, Suite 4607, 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 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
 
                                       5
<PAGE>
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, as agent for the Trustee, 14 Wall
Street, 8th Floor, Suite 4607, 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 January 1, 1946, between the Company and
First Wisconsin Trust Company (now known as Firstar Trust Company), as trustee,
and indentures supplemental thereto ("Bond Indenture").
 
THE BOND INDENTURE
 
    Security and Priority. The Bond Indenture constitutes a direct first
mortgage lien upon substantially all of the fixed property, and upon the permits
and licenses, owned by the Company, subject to "permissible encumbrances" (as
defined in the Bond Indenture). The Bond Indenture contains provisions
subjecting to the lien thereof fixed property, and permits and licenses, which
the Company may subsequently acquire, subject, however, to "permissible
encumbrances" and to liens existing or placed upon such property at the time of
acquisition thereof by the Company.
 
    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 Bond Indenture any property which is exempt from such
lien, unless 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
 
                                       6
<PAGE>
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 Bond
Indenture, the Trustee will surrender such First Mortgage Bonds to the Company
for cancellation and the 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 Regulated
Subsidiary (as defined below under "Certain Definitions") 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 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 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 $20,000,000 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
 
                                       7
<PAGE>
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
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       and       and the Record Dates will
be each       and       (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       ,       ,       and       if specified in the applicable
Prospectus Supplement, and the Record Dates will be each       ,       ,
and       (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.
 
                                       8
<PAGE>
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 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
 
                                       9
<PAGE>
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
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
 
                                       10
<PAGE>
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 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 =   360 - (D x M)       x 100
</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.
 
                                       11
<PAGE>
    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 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
 
                                       12
<PAGE>
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 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
 
                                       13
<PAGE>
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."
 
    "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
 
                                       14
<PAGE>
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 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
 
                                       15
<PAGE>
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.
 
    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."
 
                                       16
<PAGE>
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 canceled 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" 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 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" 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 canceled 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
 
                                       17
<PAGE>
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
as specified on the face of such Note, or in an annex relating thereto if so
specified on the face thereof, and/or in the applicable Prospectus Supplement.
 
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.
 
                                       18
<PAGE>
    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.
 
    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
 
                                       19
<PAGE>
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;
 
                                       20
<PAGE>
(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
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
 
                                       21
<PAGE>
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,
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;
 
                                       22
<PAGE>
(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 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 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
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
under the Indenture 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 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)

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

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

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)
 
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 this Indenture
may be served; PROVIDED that the Company may maintain at its principal executive
offices, one or more other offices or agencies for any or all of the foregoing
purposes. The Company has appointed the Trustee as agent of the Company for the
foregoing purposes. (Section 6.02)
 
REGARDING THE TRUSTEE
 
    The Trustee 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.

                 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 (including
Treasury Regulations which set forth rules applicable to debt instruments issued
with "original issue discount", the "OID 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 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 or
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 Internal Revenue Service ("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.
 
    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, (i) a
citizen or resident of the United States, (ii) a corporation, partnership or
other entity created or organized in or under the laws of the United States or
of any political subdivision thereof, or (iii) generally, an estate or trust
described in Section 7701(a)(30) of the Code. The term also includes certain
holders who are former citizens or long-term residents 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 fixed maturity date 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.
 
                                       26
<PAGE>
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.
 
    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) 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
 
                                       27
<PAGE>
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 one
year or less, 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 timing of 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 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 de minimis 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 de minimis 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
 
                                       28
<PAGE>
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 (as
described above under "Taxation of Interest--Floating Rate Notes"), 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 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 qualified stated interest 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 a Note that provides for interest at one or more
qualified floating rates or at a qualified inverse floating rate and, in
addition, at a single fixed rate, replace the fixed rate with a qualified
floating rate (or qualified inverse floating rate) such that the fair market
value of the Note, so modified, as of the issue date would be approximately the
same as the fair market value of the unmodified Note.
 
    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
 
                                       29
<PAGE>
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 (the "AFR"), announced monthly by the IRS, based on the
overall maturity of the Contingent Note. 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 OID Regulations for the Contingent Note (the
"Schedule"). The Schedule is determined 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 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 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 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
 
                                       30
<PAGE>
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 which case the market discount will be
considered to be zero.
 
    Prospective holders of Contingent Notes should carefully examine the
applicable Pricing Supplement and should consult their tax advisors regarding
the federal income tax consequences of the ownership and disposition of such
Notes. See also the discussion regarding Contingent Notes under "Sale, Exchange
or Retirement of the Notes" below.
 
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
OID 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.
 
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 under "Original Issue Discount--Fixed
Rate Notes"), 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 under the election described in the following
paragraph. 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.
 
    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.
 
                                       31
<PAGE>
    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.
 
    The application of the foregoing rules may be different in the case of
Contingent Notes. 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
 
    If a United States Holder purchases a Note for an amount in excess of the
sum of all amounts payable on the Note after the date of acquisition (other than
payments of qualified stated interest), such Holder will be considered to have
purchased such Note with "amortizable bond premium" equal in amount to such
excess, and generally will not be required to include any OID in income.
Generally, a United States Holder may elect to amortize such premium as an
offset to qualified stated interest income, using a constant yield method
similar to that described above (SEE "--Original Issue Discount Notes"), over
the remaining term of the Note (where such Note is not redeemable prior to its
maturity date). In the case of Notes that may be redeemed prior to maturity, the
premium is calculated assuming that the Company or the United States Holder will
exercise or not exercise its redemption rights in a manner that maximizes the
United States Holder's yield. A United States Holder who elects to amortize bond
premium must reduce such Holder's tax basis in the Note by the amount of the
premium used to offset qualified stated interest income as set forth above. An
election to amortize bond premium applies to all taxable debt obligations then
owned and thereafter acquired by such Holder and may be revoked only with the
consent of the IRS.
 
    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 tax 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 tax 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.
 
    The application of the foregoing rules may be different in the case of
Contingent Notes. 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.
 
                                       32
<PAGE>
    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 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 tax 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 a Note (an
"Extendible Note") or to 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.
 
    Regulations under Section 1001 of the Code (the "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
 
                                       33
<PAGE>
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
significant." With respect to certain types of debt instruments, under the
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 Section 1001 Regulations (whether or not the annual yield is
altered) if there is a "material deferral" of scheduled payments. In this
connection, the 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 generally 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 enacted in the future, 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 the option or
combination of options in a manner that minimizes the yield on the Note.
Conversely, a holder having such option or a 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 having
been retired and then 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
OID Regulations. See "Original Issue Discount--FLOATING RATE NOTES THAT ARE NOT
VRDIS."
 
    THE FOREGOING DISCUSSION OF EXTENDIBLE NOTES, RENEWABLE NOTES AND RESET

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
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 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, EXCHANGE, REDEMPTION OR RETIREMENT OF NOTES
 
    A United States Holder generally will recognize gain or loss upon the sale,
exchange, redemption or retirement of a Note equal to the difference between the
amount realized upon such sale, exchange, redemption or retirement and the
United States Holder's adjusted tax 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, taxable as ordinary income. 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" and "Short-Term Notes". The
maximum tax rate for non-corporate taxpayers on adjusted net capital gain is
20%. Adjusted net capital gain is generally the excess of net long-term capital
gain (the net gain on capital assets held for more than 12 months) over net
short-term capital loss (the net loss on capital assets held for 12 months or
less). Net short-term capital gain (net gain on assets held for 12 months or
less) is subject to tax at the same rates as ordinary income. Capital losses are
deductible by non-corporate taxpayers only to the extent of capital gains for
the taxable year plus $3,000. Capital gains are subject to tax at the same rates
as ordinary income for corporate taxpayers. Capital losses of corporate
taxpayers are deductible only against capital gains.
 
    The sale, exchange, redemption or retirement of a Contingent Note may be
subject to special rules different than those described in the preceding
paragraph and under which, except in certain circumstances, gain or loss on the
sale, exchange or retirement will be ordinary income or loss. United States
Holders of Contingent Notes should consult their tax advisors regarding the
application of these rules to their particular situations.
 
NON-UNITED STATES HOLDERS
 
    Under current United States federal income tax law, 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 beneficial owner of a Note that is not a United States
Holder (hereinafter, a 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 (under the applicable attribution rules of the Code) 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
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
 
                                       35
<PAGE>
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.
 
    On October 14, 1997, the IRS published in the Federal Register final
regulations (the "1997 Final Regulations") which affect the United States
taxation of Non-United States Holders. The 1997 Final Regulations are currently
expected to become effective for payments after December 31, 1999, regardless of
the issue date of the instrument with respect to which such payments are made,
subject to certain transition rules (see below). The discussion under this
heading and under "Backup Withholding and Information Reporting," below, is not
intended to be a complete discussion of the provisions of the 1997 Final
Regulations, and prospective purchasers of the Notes are urged to consult their
tax advisors concerning the tax consequences of their acquiring, holding and
disposing of the Notes in light of the 1997 Final Regulations.
 
    The 1997 Final Regulations provide documentation procedures designed to
simplify compliance by withholding agents. The 1997 Final Regulations generally
do not affect the documentation rules described above, but add other
certification options. Under one such option, a withholding agent will be
allowed to rely on an intermediary withholding certificate furnished by a
"qualified intermediary" (as defined below) on behalf of one or more beneficial
owners (or other intermediaries) without having to obtain the beneficial owner
certificate described above. "Qualified intermediaries" include: (i) foreign
financial institutions or foreign clearing organizations (other than a United
States branch or United States office of such institution or organization) or
(ii) foreign branches or offices of United States financial institutions or
foreign branches or offices of United States clearing organizations, which, as
to both (i) and (ii), have entered into withholding agreements with the IRS. In
addition to certain other requirements, qualified intermediaries must obtain
withholding certificates, such as revised IRS Form W-8 (see below), from each
beneficial owner. Under another option, an authorized foreign agent of a United
States withholding agent will be permitted to act on behalf of the United States
withholding agent, provided certain conditions are met.
 
    For purposes of the certification requirements, the 1997 Final Regulations
generally treat, as the beneficial owners of payments on a Note, those persons
that, under general United States federal income tax principles, are the actual
taxpayers with respect to such payments, rather than persons such as nominees or
agents legally entitled to such payments. In the case of payments to an entity
classified as a foreign partnership under United States federal income tax
principles, the partners, rather than the partnership, generally will be
required to provide the required certifications to qualify for the withholding
exemption described above. A payment to a United States partnership, however, is
treated for these purposes as payment to a United States payee, even if the
partnership has one or more foreign partners. The 1997 Final Regulations provide
certain presumptions with respect to withholding for holders not furnishing the
required certifications to qualify for the withholding exemption described
above. In addition, the 1997 Final Regulations will replace a number of current
tax certification forms (including IRS Form W-8 and IRS Form 4224, discussed
below) with a single, revised IRS Form W-8 (which, in certain circumstances,
requires information in addition to that previously required). Under the 1997
Final Regulations, this Form W-8 will remain valid until the last day of the
third calendar year following the year in which the certificate is signed.
 
    The 1997 Final Regulations provide transition rules concerning existing
certificates, such as IRS Form W-8 and IRS Form 4224. Valid withholding
certificates that are held on December 31, 1998 will generally remain valid
until the earlier of December 31, 1999 or the date of expiration of the
certificate under the
 
                                       36
<PAGE>
law in effect prior to January 1, 1999. Further, certificates dated prior to
January 1, 1998 will generally remain valid until the end of 1998, irrespective
of the date that their validity expires during 1998. The IRS has announced that
the 1997 Final Regulations will be amended to provide that valid withholding
certificates that are held on December 31, 1999, will generally remain valid
until the earlier of December 31, 2000, or the expiration of the certificate
under the law in effect prior to January 1, 2000.
 
    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 income tax 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 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 income tax
treaty) of its effectively connected earnings and profits for the taxable year,
subject to various adjustments. For this purpose, interest (including OID) and
gain (see below) 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, redemption, 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 periods aggregating
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 and certain other
requirements are met or (b) the gain is attributable to an office or other fixed
place of business maintained by such individual in the United States.
 
    Under the 1997 Final Regulations, withholding of United States federal
income tax with respect to accrued OID may apply to payments on a taxable sale
or other disposition of a Note by a Non-United States Holder who does not
provide appropriate certification to the withholding agent with respect to such
transaction.
 
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 with respect to Notes. In addition, a 31% backup withholding tax
will apply if (i) the non-corporate United States Holder 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)
the non-corporate United States Holder furnishes an incorrect TIN and the payor
is so notified by the IRS, (iii) the payor is notified by the IRS that the
non-corporate United States Holder has failed properly to report payments of
interest and dividends or (iv) in certain
 
                                       37
<PAGE>
circumstances, the non-corporate United States Holder 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 current Treasury
Regulations, backup withholding and information reporting will not apply to
payments of principal, premium and interest (including OID) 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.
 
    Under current Treasury Regulations, (i) principal or interest payments
(including OID) 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, redemption, retirement
or other disposition of a Note to or through a foreign office of a broker are
generally 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 federal income 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 other conditions are met or the beneficial owner otherwise establishes
an exemption.
 
    In general, the 1997 Final Regulations do not significantly alter the
substantive backup withholding and information reporting requirements described
above. As under current law, backup withholding and information reporting will
not apply to payments to a Non-United States Holder of principal, premium and
interest (including OID) on a Note if such Non-United States Holder provides the
required certification to establish an exemption from the withholding of United
States federal income tax or otherwise establishes an exemption. Similarly,
unless the payor has actual knowledge that the payee is a United States Holder,
backup withholding will not apply to (i) payments of interest (including OID, if
any) made outside the United States to certain offshore accounts and (ii)
payments on the sale, exchange, redemption, retirement or other disposition of a
Note effected outside the United States. However, information reporting (but not
backup withholding) will apply to (i) payments of interest made by a payor
outside the United States and (ii) payments on the sale, exchange, redemption,
retirement or other disposition of a Note effected outside the United States if
payment is made by a broker that is, for United States federal income tax
purposes, (a) a United States person, (b) a controlled foreign corporation, (c)
a United States branch of a foreign bank or foreign insurance company, (d) a
foreign partnership controlled by United States persons or engaged in a United
States trade or business or (e) 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, unless such payor or broker has in
its records documentary evidence that the beneficial owner is not a United
States Holder and certain other conditions are met or the beneficial owner
otherwise establishes an exemption.
 
    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.
 
                                 LEGAL MATTERS
 
    Legal matters with respect to the Notes will be passed upon for the Company
by Stafford, Rosenbaum, Rieser & Hansen, Madison, Wisconsin, and by Sidley &
Austin, Chicago, Illinois, and for any underwriters, dealers, purchasers or
agents by Jones, Day, Reavis & Pogue, Chicago, Illinois. The Company is advised
that as of July 21, 1998, an attorney at the firm of Stafford, Rosenbaum, Rieser
& Hansen, who has participated in the preparation of this Prospectus and the
Registration Statement, and who will participate in the rendition of the firm's
opinions with respect to the Notes and Bonds, owned beneficially 6,525 shares of
the Company's common stock.

aggregate price paid for shares of Common Stock offered under this Prospectus
and the initial public offering price of Medium-Term Notes and shares of Common
Stock offered by separate prospectuses under the registration statement referred
to below of which this Prospectus is a part, will not exceed $65,000,000.
 
Participants in the Plan may:
 
    - Make a direct Initial Investment in Common Stock with a cash payment of no
      less than $50 and no more than $25,000 per account.
 
    - Increase their investment in Common Stock by making Optional Cash Payments
      of no less than $25 per payment and no more than $25,000 for each calendar
      quarter per account.

issued shares, or treasury shares. The purchase price of shares purchased on the
open market will be the weighted average purchase price, including normal
brokerage commissions, carried to four decimal places, of shares acquired on the
open market by the Agent. The purchase price of newly issued shares or treasury
shares will be the average of the quoted closing prices, carried to four decimal
places, for the Common Stock as reported on the Nasdaq National Market for the
period of five trading days ending on the Dividend Date or Investment Date (each

                                  THE COMPANY
 
    The Company, a Wisconsin corporation organized as such in 1896, is a public
utility located in Madison, Wisconsin. It is engaged in generating and
transmitting electric energy and distributing it to approximately 117,000
customers throughout 250 square miles in Dane County. The Company also
distributes and transports natural gas to approximately 97,000 customers
throughout 975 square miles in Dane, Columbia, Iowa, Juneau, Monroe and Vernon
counties. The principal executive offices of the Company are located at 133
South Blair Street, Post Office Box 1231, Madison, Wisconsin 53701-1231, and its
telephone number is (608) 252-7000.
 
                            DESCRIPTION OF THE PLAN
 
PURPOSE
 
1.  What is the purpose of the Plan?
 
    The purpose of the Plan is to provide participants a simple and convenient
method of purchasing shares of the Company's Common Stock with Initial
Investments, dividends, and Optional Cash Payments. If such shares are purchased
from the authorized but unissued shares of the Company or from the Company's
treasury, the Company will receive additional funds which will be used for
general corporate purposes.
 
ADVANTAGES AND DISADVANTAGES
 
2.  What are the advantages of the Plan?
 
    - Persons and entities not presently owning shares of Common Stock may
      become shareholders by making an initial direct investment of no less than
      $50 and no more than $25,000 per account ("Initial Investment") (see
      Question 15).
 
    - Additional investments in Common Stock ("Optional Cash Payment") may be
      made by participants for as little as $25 per payment, up to $25,000 per
      calendar quarter per account (see Question 15).
 
    - All or a portion of Common Stock dividends may be automatically reinvested
      in additional shares of Common Stock (see Question 9).
 
    - Full investment of funds is possible under the Plan because the Plan
      permits fractional shares to be credited to participants' accounts.
 
    - Company employees who participate in the Plan may arrange for Optional
      Cash Payments to be made through payroll deductions (see Question 15).
 
    - Shares purchased are credited to an account in the participant's name, and
      a statement is furnished following each transaction, thereby providing a
      simplified method of recordkeeping (see Questions 9 and 17).
 
    - Participants may deposit Common Stock certificates into their Plan
      accounts for safekeeping, whether or not the Common Stock represented by
      such certificates was purchased through the Plan. This convenience is
      provided at no cost to the participant and eliminates the possibility of
      loss, inadvertent destruction, or theft of certificates (see Question 23).
 
    - Participants may transfer shares held in their Plan account to another
      individual or entity at no cost. The normal transfer requirements will
      apply.
 
    - Participants may receive cash dividends on any or all shares of Common
      Stock by check or electronic deposit to a designated account (see
      Questions 9 and 20).
 
                                       3
<PAGE>
3.  What are the disadvantages of the Plan?
 
    - Participants have no control over the price at which shares are purchased
      or sold through the Plan or the timing of such purchases or sales. A
      participant bears the market risk associated with fluctuations in the
      price of the Common Stock pending the execution of a purchase or sale of
      shares for the participant's account (see Question 25).
 
    - No interest is paid on funds pending investment (see Question 14).
 
    - Requests for issuance of certificates or the sale of shares from a Plan
      account (withdrawals) may be delayed during the dividend processing
      period. Requests for other changes in Plan participation may also be
      delayed during this period (see Question 25).
 
COSTS
 
4.  Are there any expenses to participants under the Plan?
 
    When shares of Common Stock purchased under the Plan are newly issued or
treasury shares, rather than shares purchased on the open market, there are no
expenses to participants because shares are purchased from the Company and no
brokerage commission is incurred. When shares of Common Stock are purchased on
the open market under the Plan, the price per share paid by the participant
includes normal brokerage commissions incurred to acquire the shares. Because
purchases are consolidated, a participant's proportionate share of brokerage
commissions resulting from open market purchases should be lower than the
commissions for individual purchases. Shares sold through the Plan will incur
normal brokerage commissions (see Question 25).
 
    The Company will pay all costs of administration of the Plan, excluding
normal brokerage commissions incurred to purchase shares on the open market or
to sell shares. Participants will receive advance notice if the Company
determines not to pay all administrative costs.
 
ADMINISTRATION
 
5.  How will the Plan be administered?
 
    The Company administers the Plan, performing only clerical and ministerial
functions such as keeping a continuing record of participants' accounts,
advising them of purchases and other transactions, and performing other duties
relating to the Plan. The Company believes that its serving as administrator
rather than a registered broker-dealer or a federally insured banking
institution poses no material risks to participants because of the
administrative nature of the functions the Company will perform. In addition,
Initial Investments and Optional Cash Investments will be transmitted promptly
to a segregated escrow account at a bank (the "Escrow Account") or to the Agent
and will not be subject to any liens or claims of any creditors of the Company.
Purchases of Common Stock for the accounts of participants will be registered in
the name of the Plan Nominee (a Bank) as custodian for participants in the Plan
(the "Nominee").
 
PARTICIPATION
 
6.  Who is eligible to participate?
 
    Any interested person or entity making an Initial Investment of at least $50
and all registered shareholders are eligible to participate. Beneficial owners
of Common Stock registered in others' names, such as brokers or bank trustees
and nominees, who want to participate by reinvesting dividends paid on these
shares may be required by their brokers or banks to withdraw their shares from
the beneficial accounts and register the shares in their own names.
 
                                       4
<PAGE>
7.  How do eligible investors participate?
 
    After receiving a Prospectus, investors may join the Plan by signing an
Enrollment Form and returning it to Madison Gas and Electric Company,
Shareholder Services Department, Post Office Box 1231, Madison, WI 53701-1231.
Enrollment Forms may be obtained at any time by written request to the Company
or by telephoning the Company at the appropriate toll-free number listed on page
15 of this Prospectus (see Question 9). Investors making first-time purchases of
Common Stock must submit the Enrollment Form with the Initial Investment to
purchase Common Stock or arrange for the Initial Investment to be made through a
payroll deduction (see Questions 14 and 15). A person who is a current owner of
Common Stock must sign an Enrollment Form exactly as such person's name appears
on his or her Common Stock certificate. If the Common Stock is registered to
more than one person, each person must sign the Enrollment Form. A person or
persons who are making an Initial Investment must specify exactly how the shares
to be purchased are to be registered and sign their names accordingly.
 
    Shareholders who are already enrolled in the Plan are eligible to
participate in the new features of the Plan. Such shareholders should carefully
review the participation options, particularly the "No Reinvestment" and
"Partial Reinvestment" options. These options have been modified in the Plan
(see Question 9). Unless such a shareholder submits a new Enrollment Form
designating a different participation option, each shareholder's current
participation in the Plan will remain unchanged.
 
8.  When may an eligible investor join the Plan?
 
    Eligible investors may join the Plan at any time. Participation for
reinvestment of dividends will commence with the next Common Stock cash dividend
date (the "Dividend Date," currently on or about March 15, June 15, September
15, and December 15) after the Company receives, at least 15 days prior to the
Dividend Date, a properly completed Enrollment Form. If the Enrollment Form is
not received in time, participation through reinvestment of dividends will be
delayed until the following Dividend Date.
 
    Optional Cash Payments received by the Company prior to the close of
business on the "Investment Date," defined as the 15th day of each month (or the
next business day thereafter if the 15th day of the month is not a business day)
and Initial Investments with a properly completed Enrollment Form received at
least three business days prior to the Investment Date will be invested monthly
on the Investment Date.
 
9.  What does an Enrollment Form authorize?
 
    An Enrollment Form authorizes the Company in its capacity as administrator
of the Plan to enroll participants under the following dividend options:
 
    - Full Dividend Reinvestment--Reinvest all dividends: dividends paid on
      shares held by the participant, dividends on shares held in the
      participant's Plan account, and any Initial Investment and Optional Cash
      Payments will be invested in Common Stock and credited to the
      participant's Plan account.
 
    - Partial Dividend Reinvestment--Reinvest a portion of dividends:
      participants may request cash dividends on a designated percentage of
      shares held by the participant and held in the participant's Plan account,
      as indicated by the participant on the Enrollment Form. Dividends paid on
      remaining shares and any Optional Cash Payments will be invested in Common
      Stock and credited to the participant's Plan account.
 
    - No Dividend Reinvestment--Pay all cash dividends: receive all cash
      dividends on shares held by the participant and in the participant's Plan
      account. Participants may purchase shares through the Plan with an Initial
      Investment and Optional Cash Payments.
 
    The Enrollment Form also allows participants to take advantage of
certificate safekeeping services (see Question 23).
 
                                       5
<PAGE>
    If the Enrollment Form is incomplete upon receipt by the Company, the
Company will return the Enrollment Form and any payment for stock purchase to
the participant.
 
SOURCE OF SHARES AND USE OF PROCEEDS
 
10. What is the source of and use of proceeds from Common Stock purchased under
    the Plan?
 
    Shares purchased under the Plan will be either shares purchased on the open
market by the Agent, newly issued shares, or treasury shares. The Company will
not change its determination regarding the source of shares more than once in
any three-month period. The Company will not exercise its right to change the
source of shares absent a determination by the Company's board of directors that
the Company's need to raise additional capital has changed, or that there is
another valid reason for such change.
 
    Initially, shares purchased under the Plan will be shares purchased on the
open market and the Company will not receive any additional funds from such
purchases. In the event the Company determines that shares to be purchased under
the Plan will be either newly issued or treasury shares, the Company will be
required to request an order from the Public Service Commission of Wisconsin
approving such purchases. If shares purchased under the Plan are newly issued or
treasury shares, the Company will receive additional funds from such purchases
to be used for general corporate purposes, including the financing of capital
expenditures, the refinancing of indebtedness, and possible investments and
acquisitions.
 
PURCHASES
 
11. How many shares of Common Stock will be purchased for participants?
 
    The number of shares to be purchased depends on the amount of a
participant's Initial Investment, Optional Cash Payment, dividend, or a
combination thereof, and the price of the shares. Each participant's account
will be credited with that number of shares, including fractions computed to
four decimal places, equal to the total amount invested divided by the purchase
price.
 
12. What will be the price of shares of Common Stock purchased under the Plan?
 
    When shares are purchased on the open market, the price per share to
participants will be the weighted average purchase price, including normal
brokerage commissions, carried to four decimal places, of shares acquired on the
open market by the Agent. Because purchases are consolidated, a participant's
proportionate share of brokerage commissions resulting from open market
purchases should be lower than the commissions for individual purchases. The
Agent is a securities broker-dealer registered as such under the Exchange Act
who is a market maker in the Common Stock and will purchase shares of Common
Stock as Agent for the participants in the Plan. The purchases will be made in
over-the-counter market purchases or negotiated transactions on terms determined
by the Agent.
 
    When shares are purchased from authorized but unissued shares of Common
Stock or from the Company's treasury, the price per share of shares to
participants will be the average of the quoted closing prices for the Common
Stock as reported on the Nasdaq National Market for the period of five trading
days ending on the Dividend Date or Investment Date (or the period of five
trading days immediately preceding the Dividend Date or the Investment Date if
the Nasdaq National Market is closed on such date). In each case, the price will
be calculated to four decimal places. No newly issued or treasury shares will be
sold for less than par value ($8 per share).
 
    The Company will pay all costs of administration of the Plan, excluding
normal brokerage commissions incurred to purchase shares on the open market or
to sell shares.
 
13. When will dividend funds be invested?
 
                                       6
<PAGE>
    On each Dividend Date, the dividends on any designated shares registered in
the names of the participants, as well as on the Common Stock held in the Plan
accounts of the participants, will be invested in Common Stock as of such
Dividend Date, along with Optional Cash Payments received prior to the close of
business on such Dividend Date (see Question 8). Dividends that are not invested
within 30 days of the Dividend Date will be paid to the shareholder. For
administrative purposes, the actual crediting of the Common Stock to a
participant's account and the purchase of shares through the Plan may take place
several days after each Dividend Date.
 
INITIAL INVESTMENTS AND OPTIONAL CASH PAYMENTS
 
14. When must the Initial Investments and Optional Cash Payments be made?
 
    Initial Investments must be received with a properly completed Enrollment
Form at least three business days prior to the Investment Date (see Question 8
for definition of Investment Date). On each Investment Date, the Company will
invest any Optional Cash Payments received prior to the close of business on the
Investment Date and Initial Investments in Common Stock for the account of such
participant. If received after the Investment Date, the Company may hold the
investment until the next Investment Date. Initial Investments and Optional Cash
Payments that are not invested within 35 days of receipt will be returned to the
participant. Only participants who have properly completed, signed, and returned
an Enrollment Form as provided in Questions 8 and 9 are eligible to make an
Initial Investment and Optional Cash Payments.
 
    A participant may withdraw an Initial Investment or Optional Cash Payment by
notifying the Company's Shareholder Services Department in writing not less than
two business days before an Investment Date. Any withdrawn amount will be
returned as promptly as practicable without interest.
 
    The Company will acknowledge receipt of all Initial Investments and Optional
Cash Payments. No interest will be paid on Initial Investments and Optional Cash
Payments held by the Company pending investment. Participants are requested not
to send cash.
 
15. How are Initial Investments and Optional Cash Payments made?
 
    Participants may make Initial Investments of not less than $50 and Optional
Cash Payments of not less than $25 per payment nor more than $25,000 for each
calendar quarter per account. When enrolling in the Plan, an Initial Investment
and Optional Cash Payment may be made by the participant by enclosing with the
Enrollment Form a check or money order payable to the order of Madison Gas and
Electric Company. Thereafter, Optional Cash Payments may be made through the use
of the Remittance Form for Optional Cash Payments sent to participants by the
Company. The Company will promptly transmit all Initial Investments and Optional
Cash Payments to the segregated Escrow Account at a bank or to the Agent.
 
    It is recommended that all payments be made so as to reach the Company at
least five business days prior to the Investment Date. Each payment by a
participant must be made by check or money order payable to the order of Madison
Gas and Electric Company and the same amount of money need not be sent each
time, subject to the minimum and maximum payment levels. There is no obligation
to make Optional Cash Payments.
 
    Employees of the Company or its subsidiaries participating in the Plan may
arrange for an Initial Investment or Optional Cash Payments to be made through
payroll deductions. The $50 and $25 minimum payment requirement for Initial
Investments and Optional Cash Payments, respectively, will not apply to payments
made through payroll deductions. Application forms for such employee payroll
deductions are available from the Company's Shareholder Services Department.
Commencement, revision, or termination of payroll deductions will become
effective as soon as practicable after receipt of the request.
 
16. What happens if a check is returned unpaid by a participant's financial
    institution?
 
                                       7
<PAGE>
    In the event that any check is returned unpaid for any reason and the
Company is unable to collect funds from the participant, the Company will
consider the request for investment of such funds null and void. The Company
shall remove from the participant's account any shares purchased upon the prior
credit of such funds. Those shares may be sold to satisfy any uncollected
amount. If the net proceeds of such sale are insufficient to satisfy the balance
of such uncollected amount, additional shares may be sold from the participant's
account as necessary to satisfy the uncollected balance.
 
REPORTS TO PARTICIPANTS
 
17. What kind of reports will be sent to participants in the Plan?
 
    Each participant will receive a statement of account following each purchase
or sale of Common Stock for the participant's account under the Plan. Statements
of account will be issued quarterly for all Plan participants and for each month
when the participant purchases or sells shares. Quarterly statements of account
are cumulative, showing activity for all three months of the quarter and
calendar year to date. Account statements are the participant's continuing
record of purchases and should be retained for income tax purposes. The final
statement of the calendar year will indicate the total dividends credited to the
participant's account for the year for the participant's Plan account, and a
Form 1099-DIV will be issued to each participant for use in reporting dividends
received for income tax purposes.
 
    For participants who are not making Optional Cash Payments or reinvesting
dividends but have shares held in the Plan, information regarding share balances
and year-to-date dividends will accompany their dividend check.
 
18. What other communications will participants receive from the Company?
 
    Each participant will receive the same communications as every other
shareholder of record, including Quarterly Reports, the Annual Report, the
Notice of Annual Meeting of Shareholders and the Proxy Statement, Proxy, and
income tax information, including 1099 forms for reporting dividends and sale
proceeds received by the participant. See Question 29 regarding voting of
proxies.
 
DIVIDENDS ON FRACTIONS OF SHARES AND ELECTRONIC DEPOSIT
 
19. Will participants be paid or credited with dividends on fractions of shares?
 
    Yes.
 
20. Will the Company automatically deposit dividends which are not reinvested
    directly into a participant's designated account?
 
    In lieu of receiving dividends by check, a participant may receive dividends
by electronic deposit to a designated account. A participant must complete and
sign a direct deposit authorization form and return it to Madison Gas and
Electric Company, Shareholder Services Department, Post Office Box 1231,
Madison, WI 53701-1231. Direct deposit will become effective as soon as
practicable after receipt of a properly completed direct deposit authorization
form. Changes in direct deposit instructions may be made by delivering a new
properly completed direct deposit authorization form.
 
CERTIFICATES FOR SHARES
 
21. Will certificates be issued for the Common Stock purchased?
 
    Normally, certificates for Common Stock purchased under the Plan will not be
issued to participants. Instead, the Common Stock purchased for each participant
will be credited to the participant's Plan account by the Company and will be
shown on the participant's statement of account. This convenience protects
against loss, theft, or destruction of Common Stock certificates. See Question
17 regarding issuance of statements of account.
 
                                       8
<PAGE>
    Certificates for any number of whole shares credited to an account under the
Plan will be issued in the participant's name upon the written request of a
participant. A participant must furnish separate written instructions to the
Company each time the issuance of certificates is desired. Requests should be
mailed to Madison Gas and Electric Company, Shareholder Services Department,
Post Office Box 1231, Madison, WI 53701-1231. Requests for certificates will be
handled without charge to participants, but participants are restricted to one
request per quarter.
 
    Certificates for fractions of shares will not be issued to a participant
under any circumstances. See Questions 24 and 25 regarding withdrawal of
fractional shares from the Plan.
 
    Common Stock credited to the account of a participant under the Plan may not
be pledged. A participant who wishes to pledge Common Stock must request that
certificates for such Common Stock be issued in his or her name.
 
22. In whose name will certificates be registered when issued?
 
    Accounts in the Plan will be maintained in a participant's name as shown on
the Company's shareholder records. Certificates for whole shares will be
similarly registered when issued.
 
    Upon written request, certificates can also be registered and issued in
names other than that of a participant, subject to compliance with any
applicable laws and to payment by the participant of any applicable taxes, and
provided that the request, in proper form, bears the signature of the
participant and the signature is guaranteed by an eligible financial institution
acceptable to the Company's transfer agent.
 
SAFEKEEPING OF CERTIFICATES
 
23. Can certificates be sent to the Company for safekeeping?
 
    Participants who wish to have the Company hold their certificated shares in
safekeeping may send the certificate(s) to the Company for deposit to a Plan
account in the participant's name. Send the certificate, unsigned, with an
Enrollment Form to Madison Gas and Electric Company, Shareholder Services
Department, Post Office Box 1231, Madison, WI 53701-1231. Enrollment Forms may
be obtained at any time by writing to the Company or telephoning the Company at
the appropriate toll-free number listed on page 15. It is recommended the
certificate(s) be sent by registered or certified mail, return receipt
requested. Participants bear all risk of loss in sending certificates for
safekeeping. Certificates received for safekeeping will be canceled and
registered in the name of the Nominee as custodian for participants in the Plan.
Participants using safekeeping services must advise the Company as to their
choice of dividend payment options by indicating their choice on the Enrollment
Form under "Participation."
 
WITHDRAWAL
 
24. What are the options for withdrawal of Common Stock from the Plan?
 
    When a participant withdraws all or a portion of his or her Common Stock
from the Plan, the participant has five options. A participant may elect (i) to
have a certificate issued for all of the whole shares credited to the
participant's Plan account and receive a cash payment for any fraction of a
share, (ii) to have the Company sell all of the participant's Plan shares and
receive a check for the proceeds, (iii) to have a certificate issued for a
specified number of whole shares to be withdrawn from the Plan, leaving the
remaining shares in the Plan, (iv) to have the Company sell a specified number
of Plan shares and receive a check for the proceeds, leaving the remaining
shares in the Plan, or (v) to discontinue reinvestment of dividends but continue
to have shares held in safekeeping.
 
25. When and how may participants withdraw all or a portion of their Common
    Stock from the Plan?
 
    A participant may withdraw from the Plan at any time by sending a written
request to Madison Gas and Electric Company, Shareholder Services Department,
Post Office Box 1231, Madison, WI 53701-1231.
 
                                       9
<PAGE>
    When a participant requests to withdraw all of his or her Common Stock from
the Plan, termination of participation in the Plan will be effective upon the
issuance of a certificate or sale of his or her Common Stock. If a participant
withdraws all of his or her Common Stock from the Plan and requests a
certificate for the shares, a certificate for all of the whole shares credited
to the participant's Plan account will be issued and a cash payment representing
any fraction of a share will be mailed directly to the participant. The cash
payment to each such participant will be based on the actual sales price when
accumulated fractional sales of withdrawing participants are sold through the
Plan.
 
    If a request for withdrawal is received less than 30 days preceding a
Dividend Date, the request may be held until dividend processing is complete.
 
    Sales of whole shares and any fractional shares will be made directly to the
Agent. The sale price to participants of shares sold through the Plan will be
the market price, including normal brokerage commissions, carried to four
decimal places, of shares purchased by the Agent. Sale proceeds will be mailed
to the participant. Sales of whole and fractional shares may be accumulated;
sales transactions will, however, normally occur weekly and at least every 30
days. Participants will receive certificates for shares or cash for shares which
are sold no later than 30 days after the Company's receipt of the written notice
of withdrawal.
 
    The Company cannot guarantee that shares will be sold on any specific day or
at any specific price.
 
26. When may former participants rejoin the Plan?
 
    Generally, a former participant may again become a participant at any time
(see Question 8). However, the Company reserves the right to reject any
Enrollment Form from a previous participant on grounds of excessive joining and
termination. Such reservation is intended to minimize unnecessary administrative
expense and to encourage use of the Plan as a long-term investment service.
 
OTHER INFORMATION
 
27. When and how may participants change their status concerning dividend
    reinvestment in the Plan?
 
    Participants may change their status at any time by indicating a new
designation on an Enrollment Form. However, if a participant's request to change
is received less than 30 days preceding a Dividend Date, the dividend paid on
such date may, at the option of the Company, be processed under the
participant's previous designation. All requests to change will be processed as
promptly as possible.
 
28. What happens if the Company issues a stock dividend or declares a stock
    split?
 
    Any stock dividends or split shares distributed by the Company on Common
Stock held in the Plan for a participant will be credited to the participant's
Plan account. Stock dividends or split shares distributed on certificated shares
registered in the name of a participant will be registered in the participant's
name and may be issued in certificate form.
 
29. How will participants' Common Stock be voted at meetings of shareholders?
 
    The Common Stock credited to a participant's account may only be voted in
accordance with the participant's instructions given on a proxy form which will
be furnished to all shareholders.
 
30. What is the responsibility of the Company and the Nominee under the Plan?
 
    Neither the Company, the Agent, the Nominee, nor any agents, in
administering the Plan, will be liable for any act done in good faith, or for
any omission to act in good faith, including, without limitation, any act giving
rise to a claim of liability arising out of failure to terminate a participant's
account upon such participant's death prior to the receipt of notice in writing
of such death.
 
    A participant should recognize that neither the Company, the Agent, the
Nominee, nor any agents can assure a profit or protect against a loss on the
Common Stock purchased or sold under the Plan.
 
                                       10
<PAGE>
    The foregoing does not affect a participant's right to bring a cause of
action based on alleged violations of federal securities laws.
 
31. What provision is made for shareholders whose dividends are subject to tax
    withholding?
 
    In the case of participating shareholders whose dividends are subject to tax
withholding, the Company will invest an amount equal to the cash dividend
declared by the Company less the amount of tax required to be withheld. Only the
net dividend will be applied by the Company to the purchase of Common Stock. The
Company's quarterly statements for such participants will indicate the amount of
tax withheld and the net dividend reinvested by the Company.
 
32. Can the Plan be changed or discontinued?

any time. Notice of any such suspension, modification, or termination will be
sent to all affected participants.
 
33. Who interprets and regulates the Plan?
 
    The Company reserves the right to interpret and regulate the Plan.
 
34. Which law governs the Plan?
 
    The Plan is governed by and construed in accordance with the laws of the
State of Wisconsin.
 
FEDERAL INCOME TAX CONSEQUENCES
 
    The federal income tax information in Questions 35 through 37 is provided
only as a guide to noncorporate participants who hold shares of Common Stock as
a capital asset. All participants are urged to consult with their own tax
advisors for more specific information on rules regarding the tax consequences
of the Plan under federal and state income tax laws and the tax basis of shares
held under the Plan in special cases, such as the death of a participant or a
gift of such shares and for other tax consequences.
 
    Because state income tax laws vary between states, information on state tax
consequences is not discussed in this Prospectus. Plan participants are urged to
consult with their own tax advisors regarding the tax consequences of Plan
participation under the specific state and local income tax laws to which they
are subject.
 
35. What are the federal income tax consequences of participation in the Plan?
 
    Participants in the Plan will be subject to federal income tax on dividends
they elect to have reinvested under the Plan even though such Participants will
not actually receive cash. If the shares purchased with such reinvested
dividends are purchased on the open market, the participant will be treated for
federal income tax purposes as having received the cash dividend used to
purchase such shares. If the shares purchased with such reinvested dividends are
newly issued or treasury shares, the participant will be treated as having
received a taxable dividend in an amount equal to the fair market value of such
shares on the Dividend Date.
 
    Generally, any dividends described above will be taxable to participants as
ordinary dividend income to the extent of the Company's current or accumulated
earnings and profits for federal income tax purposes. The amount of any
dividends in excess of such earnings and profits will reduce a participant's tax
basis in the Common Stock with respect to which such dividend was received, and,
to the extent in excess of such basis, result in capital gain.
 
    Participants in the Plan will not recognize any income for federal income
tax purposes upon the purchase of shares of Common Stock with Initial
Investments and Optional Cash Payments. See Question 36 regarding the tax basis
of such shares.
 
                                       11
<PAGE>
36. What is the federal income tax basis and holding period of shares of Common
    Stock acquired under the Plan?
 
    As a general rule, the tax basis of shares (or any fraction of a share) of
Common Stock acquired under the Plan will equal (i) in the case of shares
purchased on the open market, the purchase price for such shares (or fractional
share), including any brokerage commissions, and (ii) in the case of newly
issued shares or treasury shares, the fair market value of such shares on the
Dividend Date.
 
    The holding period for shares of Common Stock acquired under the Plan (or a
fraction thereof) will begin on the day following the purchase date.
 
37. What are the federal income tax consequences of a sale of Common Stock
    acquired under the Plan?
 
    A participant will not be subject to any federal income tax upon receipt of
certificates for whole shares of Common Stock previously credited to the
participant's account, whether upon request, withdrawal from the Plan, or the
Company's termination thereof. However, gain or loss will be realized when
shares are sold and with respect to any cash payment by the Company in lieu of
issuance of a fractional share of Common Stock. The gain or loss will be equal
to the difference between the amount received for such shares and the
participant's tax basis therefor. If shares of Common Stock acquired under the
Plan are held for more than one year, the gain or loss realized upon the sale
thereof generally will be long-term capital gain or loss; if such shares are
held for a shorter period, such gain or loss will be short-term capital gain or
loss.

                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
    The Company is authorized by its Restated Articles of Incorporation, as
amended (the "Articles"), to issue 50,000,000 shares of Common Stock ($1 par
value), of which 16,079,718 shares were issued and outstanding as of March 31,
1998, and 1,175,000 shares of $25 par value redeemable preferred stock,
cumulative, no shares of which are outstanding. None of the Common Stock has
been redeemed or is held as treasury stock.
 
    The following statements are summaries relating to the Common Stock of
certain provisions of the Articles, of the Wisconsin Business Corporation Law,
and of the Company's Indenture of Mortgage and Deed Trust (the "Indenture").
 
VOTING RIGHTS NONCUMULATIVE VOTING
 
    Except as described below under "Limitation of Voting Rights of Substantial
Shareholders," each share of Common Stock entitles the holder thereof to one
vote for each share held on each matter submitted to a vote at a meeting of
shareholders and in all elections of directors. Since the Common Stock does not
have cumulative voting rights, the holders of more than 50% of the shares, if
they choose to do so, can elect all of the directors. The holders of Common
Stock exclusively possess the full voting power of the Company.
 
LIMITATION OF VOTING RIGHTS OF SUBSTANTIAL SHAREHOLDERS
 
    The Company's Articles provide that so long as any person is a Substantial
Shareholder (as defined), the record holders of the shares of the Company's
Voting Stock (as defined) beneficially owned by such Substantial Shareholder
have limited voting rights. These provisions may render more difficult or
discourage a merger or takeover of the Company, the acquisition of control of
the Company by a Substantial Shareholder, and the removal of incumbent
management. "Voting Stock" is defined to include Common Stock and any class or
series of preferred or preference stock then outstanding entitling the holder
thereof to vote on the matter with respect to which a determination is being
made, unless the shareholders or Board of Directors expressly exempt such class
or series from such provisions.
 
    A "Substantial Shareholder" is defined as any person or entity (other than
the Company or a subsidiary and other than employee benefit plans of the Company
or any subsidiary and the trustees thereof), or any group formed for the purpose
of acquiring, holding, voting, or disposing of shares of Voting Stock, that is
the beneficial owner of Voting Stock representing 10% or more of the votes
entitled to be cast by the holders of all the then outstanding shares of Voting
Stock. For purposes of the Articles, a person is deemed to be a "beneficial
owner" of any shares of Voting Stock which such person (or any of its affiliates
or associates) beneficially owns, directly or indirectly, or has the right to
acquire or to vote, or which are beneficially owned, directly or indirectly, by
any other person with which such person (or any of its affiliates or associates)
has an agreement, arrangement, or understanding for the purpose of acquiring,
holding, voting, or disposing of Voting Stock.
 
    A Substantial Shareholder (including the shareholders of record of its
beneficially owned shares) is entitled to cast one vote per share (or such other
number of votes per share as may be specified in or pursuant to the Articles)
with respect to the shares of Voting Stock which would entitle such Substantial
Shareholder to cast up to 10% of the total number of votes entitled to be cast
in respect of all the outstanding shares of Voting Stock. With respect to shares
of Voting Stock that would entitle such Substantial Shareholder to cast more
than 10% of such total number of votes, however, the Substantial Shareholder is
entitled to only one/one-hundredth (1/100th) of the votes per share which it
would otherwise be entitled to cast. In addition, in no event may such
Substantial Shareholder exercise more than
 
                                       13
<PAGE>
15% of the total voting power of the holders of Voting Stock (after giving
effect to the foregoing limitations).
 
    If the shares of Voting Stock beneficially owned by a Substantial
Shareholder are held of record by more than one person, the aggregate voting
power of all such persons, as limited by the provisions described above, will be
allocated in proportion to the number of shares held. In addition, the Articles
provide that a majority of the voting power of all the outstanding shares of
Voting Stock (after giving effect to the foregoing limitations on voting rights)
constitutes a quorum at all meetings of shareholders.
 
    The following is an example of how the foregoing provisions would operate if
the Company had 1,000 outstanding shares of Voting Stock. If a Substantial
Shareholder beneficially owned 600 of the shares, he or she would be entitled to
100 votes for his or her first 100 shares and, on the basis of the limitation on
voting rights with respect to shares in excess of 10%, an additional five votes
for his or her remaining 500 shares. These 105 votes would be out of a total of
505 votes then entitled to be cast (that is, 105 votes by the Substantial
Shareholder and 400 votes by all other shareholders). Then, because these 105
votes would constitute 21% of the total number of votes, the provisions of the
Articles would further limit the Substantial Shareholder to approximately 71
votes of a total of approximately 471 entitled to be cast by all shareholders
(15% of the total number of votes entitled to be cast). As a result of the
limitation of the Substantial Shareholder's voting rights, the voting power of
the other shareholders increases from 40% to 85%.
 
    Accordingly, beneficial owners of more than 10% of the outstanding shares of
Voting Stock will be unable to exercise voting rights proportionate to their
equity interests.
 
    Generally, Section 180.1150 of the Wisconsin Statutes states that the voting
power of shares of certain Wisconsin corporations, including the Company, held
by any person in excess of 20% of the voting power in the election of directors
is limited to 10% of his or her full voting power. In other words, a person
holding 500 shares of such a corporation with 1,000 shares outstanding would be
limited to 230 votes on any matter subjected to a shareholder vote. Full voting
power may be restored if a majority of the voting power shares represented at a
meeting are voted in favor of such a restoration.
 
DIVIDEND RIGHTS
 
    Dividends may be paid upon the Common Stock as and when declared by the
Board of Directors out of any funds legally available therefor.
 
    Under the terms of three supplemental indentures to the Indenture, so long
as any of the bonds authorized by any such Supplemental Indenture are
outstanding, dividends on the Common Stock cannot exceed retained income less
such dividends less the excess of the maintenance and replacement requirements
over the maintenance, repairs, and depreciation expenses, in each case
accumulated since December 31, 1945. No portion of retained income is so
restricted at this time.
 
    Under the terms of all other supplemental indentures to the Indenture, so
long as any of the bonds authorized by any such Supplemental Indenture are
outstanding, dividends on the Common Stock cannot exceed retained income less
such dividends, in each case accumulated since December 31, 1945. No portion of
retained income is so restricted at this time.
 
LIQUIDATION RIGHTS
 
    In the event the Company is liquidated or dissolved, after all of the
Company's liabilities have been paid, and after any holders of any other stock
having senior liquidation preferences to Common Stock have been paid or had
funds set aside in accordance with the Articles, the holders of the then
outstanding Common Stock are entitled to receive pro rata the remaining assets
available for distribution.
 
                                       14
<PAGE>
PREEMPTIVE AND SUBSCRIPTION RIGHTS
 
    No holder of any class of stock of the Company, including the Common Stock,
has any preemptive or subscription rights.
 
LIABILITY TO FURTHER CALLS OR TO ASSESSMENT
 
    The shares of Common Stock, when issued and delivered by the Company and
paid for as herein contemplated, will be fully paid and nonassessable by the
Company. However, in accordance with Section 180.0622(2)(b) of the Wisconsin
Business Corporation Law, shareholders may be personally liable for an amount
equal to the par value for all debts owing to employees of the Company for
services performed, but not exceeding six months' service in any one case.
 
MISCELLANEOUS
 
    The Company reserves the right to increase, decrease, or reclassify its
authorized capital stock, or any class or series thereof, and to amend or repeal
any provisions in the Articles or in any amendment thereto in the manner now or
hereafter prescribed by law, subject to the limitations in the Articles; and all
rights conferred on the holders of Common Stock in the Articles or any amendment
thereto are subject to this reservation. There are no conversion rights with
respect to any class of capital stock of the Company.
 
                       COMMON STOCK DIVIDENDS AND MARKET
 
    The Company has paid dividends on Common Stock in varying amounts since it
became publicly held.
 
    The Company's practice of paying dividends quarterly (in March, June,
September, and December), the time of payment, and the amount of future
dividends are necessarily dependent upon, the Company's earnings, financial
requirements, and other factors.
 
    The Common Stock is traded in the over-the-counter market and is quoted on
the Nasdaq National Market under the symbol "MDSN."

                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
    The Company is authorized by its Restated Articles of Incorporation, as
amended (the "Articles"), to issue 50,000,000 shares of Common Stock ($1 par
value), of which 16,079,718 shares were issued and outstanding as of March 31,
1998, and 1,175,000 shares of $25 par value redeemable preferred stock,
cumulative, no shares of which are outstanding. None of the Common Stock has
been redeemed or is held as treasury stock.
 
    The following statements are summaries relating to the Common Stock of
certain provisions of the Articles, of the Wisconsin Business Corporation Law,
and of the Company's Indenture of Mortgage and Deed Trust (the "Indenture").
 
VOTING RIGHTS NONCUMULATIVE VOTING
 
    Except as described below under "Limitation of Voting Rights of Substantial
Shareholders," each share of Common Stock entitles the holder thereof to one
vote for each share held on each matter submitted to a vote at a meeting of
shareholders and in all elections of directors. Since the Common Stock does not
have cumulative voting rights, the holders of more than 50% of the shares, if
they choose to do so, can elect all of the directors. The holders of Common
Stock exclusively possess the full voting power of the Company.
 
LIMITATION OF VOTING RIGHTS OF SUBSTANTIAL SHAREHOLDERS
 
    The Company's Articles provide that so long as any person is a Substantial
Shareholder (as defined), the record holders of the shares of the Company's
Voting Stock (as defined) beneficially owned by such Substantial Shareholder
have limited voting rights. These provisions may render more difficult or
discourage a merger or takeover of the Company, the acquisition of control of
the Company by a Substantial Shareholder, and the removal of incumbent
management. "Voting Stock" is defined to include Common Stock and any class or
series of preferred or preference stock then outstanding entitling the holder
thereof to vote on the matter with respect to which a determination is being
made, unless the shareholders or Board of Directors expressly exempt such class
or series from such provisions.
 
    A "Substantial Shareholder" is defined as any person or entity (other than
the Company or a subsidiary and other than employee benefit plans of the Company
or any subsidiary and the trustees thereof), or any group formed for the purpose
of acquiring, holding, voting, or disposing of shares of
 
                                       3
<PAGE>
Voting Stock, that is the beneficial owner of Voting Stock representing 10% or
more of the votes entitled to be cast by the holders of all the then outstanding
shares of Voting Stock. For purposes of the Articles, a person is deemed to be a
"beneficial owner" of any shares of Voting Stock which such person (or any of
its affiliates or associates) beneficially owns, directly or indirectly, or has
the right to acquire or to vote, or which are beneficially owned, directly or
indirectly, by any other person with which such person (or any of its affiliates
or associates) has an agreement, arrangement, or understanding for the purpose
of acquiring, holding, voting, or disposing of Voting Stock.
 
    A Substantial Shareholder (including the shareholders of record of its
beneficially owned shares) is entitled to cast one vote per share (or such other
number of votes per share as may be specified in or pursuant to the Articles)
with respect to the shares of Voting Stock which would entitle such Substantial
Shareholder to cast up to 10% of the total number of votes entitled to be cast
in respect of all the outstanding shares of Voting Stock. With respect to shares
of Voting Stock that would entitle such Substantial Shareholder to cast more
than 10% of such total number of votes, however, the Substantial Shareholder is
entitled to only one/one-hundredth (1/100th) of the votes per share which it
would otherwise be entitled to cast. In addition, in no event may such
Substantial Shareholder exercise more than 15% of the total voting power of the
holders of Voting Stock (after giving effect to the foregoing limitations).
 
    If the shares of Voting Stock beneficially owned by a Substantial
Shareholder are held of record by more than one person, the aggregate voting
power of all such persons, as limited by the provisions described above, will be
allocated in proportion to the number of shares held. In addition, the Articles
provide that a majority of the voting power of all the outstanding shares of
Voting Stock (after giving effect to the foregoing limitations on voting rights)
constitutes a quorum at all meetings of shareholders.
 
    The following is an example of how the foregoing provisions would operate if
the Company had 1,000 outstanding shares of Voting Stock. If a Substantial
Shareholder beneficially owned 600 of the shares, he or she would be entitled to
100 votes for his or her first 100 shares and, on the basis of the limitation on
voting rights with respect to shares in excess of 10%, an additional five votes
for his or her remaining 500 shares. These 105 votes would be out of a total of
505 votes then entitled to be cast (that is, 105 votes by the Substantial
Shareholder and 400 votes by all other shareholders). Then, because these 105
votes would constitute 21% of the total number of votes, the provisions of the
Articles would further limit the Substantial Shareholder to approximately 71
votes of a total of approximately 471 entitled to be cast by all shareholders
(15% of the total number of votes entitled to be cast). As a result of the
limitation of the Substantial Shareholder's voting rights, the voting power of
the other shareholders increases from 40% to 85%.
 
    Accordingly, beneficial owners of more than 10% of the outstanding shares of
Voting Stock will be unable to exercise voting rights proportionate to their
equity interests.
 
    Generally, Section 180.1150 of the Wisconsin Statutes states that the voting
power of shares of certain Wisconsin corporations, including the Company, held
by any person in excess of 20% of the voting power in the election of directors
is limited to 10% of his or her full voting power. In other words, a person
holding 500 shares of such a corporation with 1,000 shares outstanding would be
limited to 230 votes on any matter subjected to a shareholder vote. Full voting
power may be restored if a majority of the voting power shares represented at a
meeting are voted in favor of such a restoration.
 
DIVIDEND RIGHTS
 
    Dividends may be paid upon the Common Stock as and when declared by the
Board of Directors out of any funds legally available therefor.
 
    Under the terms of three supplemental indentures to the Indenture, so long
as any of the bonds authorized by any such Supplemental Indenture are
outstanding, dividends on the Common Stock cannot
 
                                       4
<PAGE>
exceed retained income less such dividends less the excess of the maintenance
and replacement requirements over the maintenance, repairs, and depreciation
expenses, in each case accumulated since December 31, 1945. No portion of
retained income is so restricted at this time.
 
    Under the terms of all other supplemental indentures to the Indenture, so
long as any of the bonds authorized by any such Supplemental Indenture are
outstanding, dividends on the Common Stock cannot exceed retained income less
such dividends, in each case accumulated since December 31, 1945. No portion of
retained income is so restricted at this time.
 
LIQUIDATION RIGHTS
 
    In the event the Company is liquidated or dissolved, after all of the
Company's liabilities have been paid, and after any holders of any other stock
having senior liquidation preferences to Common Stock have been paid or had
funds set aside in accordance with the Articles, the holders of the then
outstanding Common Stock are entitled to receive pro rata the remaining assets
available for distribution.
 
PREEMPTIVE AND SUBSCRIPTION RIGHTS
 
    No holder of any class of stock of the Company, including the Common Stock,
has any preemptive or subscription rights.
 
LIABILITY TO FURTHER CALLS OR TO ASSESSMENT
 
    The shares of Common Stock, when issued and delivered by the Company and
paid for as herein contemplated, will be fully paid and nonassessable by the
Company. However, in accordance with Section 180.0622(2)(b) of the Wisconsin
Business Corporation Law, shareholders may be personally liable for an amount
equal to the par value for all debts owing to employees of the Company for
services performed, but not exceeding six months' service in any one case.
 
MISCELLANEOUS
 
    The Company reserves the right to increase, decrease, or reclassify its
authorized capital stock, or any class or series thereof, and to amend or repeal
any provisions in the Articles or in any amendment thereto in the manner now or
hereafter prescribed by law, subject to the limitations in the Articles; and all
rights conferred on the holders of Common Stock in the Articles or any amendment
thereto are subject to this reservation. There are no conversion rights with
respect to any class of capital stock of the Company.
 
                       COMMON STOCK DIVIDENDS AND MARKET
 
    The Company has paid dividends on Common Stock in varying amounts since it
became publicly held.
 
    The Company's practice of paying dividends quarterly (in March, June,
September, and December), the time of payment, and the amount of future
dividends are necessarily dependent upon, the Company's earnings, financial
requirements, and other factors.
 
    The Common Stock is traded in the over-the-counter market and is quoted on
the Nasdaq National Market under the symbol "MDSN."
 
                              PLAN OF DISTRIBUTION
 
    The Company may sell shares of Common Stock 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 the respect to the shares
of Common Stock being offered (the "Offered Shares") will set forth the terms of
the offering of the Offered Shares, including the name or names of any
underwriters or agents, the purchase price of the Offered Shares and the
proceeds
 
                                       5
<PAGE>
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 Shares 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 shares
of Common Stock 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 shares of Common Stock, 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 Shares will be subject
to conditions precedent and the underwriters will be obligated to purchase all
of the Offered Shares if any are purchased.
 
    If dealers are utilized in the sale of Offered Shares in respect of which
this Prospectus is delivered, and if so specified in the applicable Prospectus
Supplement, the Company will sell such Offered Shares to the dealers as
principals. The dealers may then resell such Offered Shares 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 shares of Common Stock 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 Shares 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.
 
                                 LEGAL MATTERS
 
    Legal matters with respect to the shares of Common Stock will be passed upon
for the Company by Stafford, Rosenbaum, Rieser & Hansen, Madison, Wisconsin, and
by Sidley & Austin, Chicago, Illinois, and for any underwriters, dealers,
purchasers or agents by Jones, Day, Reavis & Pogue, Chicago, Illinois. The
Company is advised that as of July 21, 1998, an attorney at the firm of

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Pursuant to the provisions of the Wisconsin Business Corporation Law and
Article IX of the Registrant's By-Laws, directors and officers of the Registrant
are entitled to mandatory indemnification from the Registrant against certain
liabilities (which may include liabilities under the Securities Act of 1933) and
expenses (i) to the extent such officers or directors are successful in the
defense of a proceeding; and (ii) in proceedings in which the director or
officer is not successful in defense thereof, unless it is determined that the
director or officer breached or failed to perform his or her duties to the
Registrant and such breach or failure constituted: (a) a willful failure to deal
fairly with the Registrant or its shareholders in connection with a matter in
which the director or officer had a material conflict of interest; (b) a
violation of criminal law unless the director or officer had reasonable cause to
believe his or her conduct was lawful or had no reasonable cause to believe his
or her conduct was unlawful; (c) a transaction from which the director or
officer derived an improper personal profit; or (d) willful misconduct.
Additionally, under the Wisconsin Business Corporation Law, directors of the
Registrant are not subject to personal liability to the Registrant, its
shareholders, or any person asserting rights on behalf thereof, for certain
breaches or failures to perform any duty resulting solely from their status as
directors, except in circumstances paralleling those outlined above.
 
    Directors and officers of the Registrant are insured, at the expense of the
Registrant, against certain liabilities which might arise out of their
employment and which might not be indemnified or indemnifiable under the
By-laws. The primary coverage is provided by a Directors and Officers Liability
Insurance Policy in customary form having a one-year term. The coverage also
applies to directors and officers of subsidiaries of the Registrant. No
deductibles or retentions apply to individual directors or officers.

ITEM 17. UNDERTAKINGS.
 
    (a) The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
        (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;
 
        (ii) 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 and 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 20 percent change in the maximum aggregate
    offering price set forth in the "Calculation of Registration Fee" table in
    the effective registration statement; and
 
        (iii) 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;
 
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and 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.
 
    (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.
 
    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant'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.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has 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 the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
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 registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                DISTRIBUTION AGREEMENT



                                                           _______________, 1998

Agents
Addresses

Dear Sirs:

          Madison Gas and Electric Company, a Wisconsin corporation (the
"Company"), confirms its agreement with ________________________________
___________________ (each, an "Agent" and, together, the "Agents") 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 _______________, 1998 between the Company and 
Bank One, N.A., as trustee (the "Trustee").  As of the date hereof, the 
Company has authorized the issuance and sale of up to $65,000,000 aggregate 
principal amount of Notes through the Agents 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 Agents 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 Agents will act as agents of the Company in
soliciting Note purchases, and (as may from time to time be agreed to by the
Company and the Agents) to the Agents as principal for resale to purchasers.

     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, 

<PAGE>

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 (including pricing 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 Notes shall be provided to the Agents by 
the Company for use in connection with the offering of 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 AGENTS.

     (a)  APPOINTMENT OF AGENTS.  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 each Agent as its agent
for the purpose of soliciting purchases of Notes from the Company by others and
agrees that, except as otherwise contemplated herein, whenever the Company
determines to sell Notes directly to an Agent or Agents 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 Agents
are authorized to appoint sub-agents or to engage the services of any other
broker or dealer in connection with the offer or sale of Notes.  The Company
agrees that, during the period any Agent is acting as the Company's Agent
hereunder, the Company will not contact or solicit potential investors
introduced to it by such Agent to purchase Notes.  The Company may appoint, upon
one day prior written notice to the Agents, additional persons to serve as Agent
hereunder, but 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 Agents will use 

                                       2

<PAGE>

their reasonable efforts to solicit purchases of such principal amount of 
Notes as the Company and the Agents 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 Agents 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 
Agents will communicate to the Company, orally or in writing, each offer to 
purchase Notes, other than those offers rejected by an Agent.  Each 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 such Agent's agreement contained herein.  The 
Company may accept or reject any proposed purchase of Notes, in whole or in 
part.

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

     (d)  RELIANCE.  The Company and each Agent agree that any Notes the
placement of which such Agent arranges shall be placed by such Agent, and any
Notes purchased by such 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.

SECTION 2.     REPRESENTATIONS AND WARRANTIES.

     (a)  The Company represents and warrants to each 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 any Agent as agent or to any Agent as 
principal), as of the date of each delivery of Notes (whether through such 
Agent as agent or to such Agent as principal) (the date of each such delivery 
to such Agent as principal being hereafter referred to as a "Settlement 
Date"), 

                                       3

<PAGE>

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 
Agents 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 Wisconsin 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 not required to be
     qualified as a foreign corporation to transact business in any other
     jurisdiction.

         (ii)  SUBSIDIARIES.  The Company has no significant subsidiaries, as
     "significant subsidiary" is defined in Rule 405 of Regulation C of the 1933
     Act Regulations.
     
         (iii) 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, in the light of the circumstances under which they
     were made, 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 (A) the Statement of Eligibility and Qualification (Form T-1) of the
     Trustee or (B) the Registration Statement or Prospectus made in reliance
     upon and in conformity with 

                                       4

<PAGE>

     information furnished to the Company in writing by the Agents expressly 
     for use in the Registration Statement or Prospectus.

        (iv) 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.

          (v) ACCOUNTANTS.  The accountants who issued their reports on the
     financial statements included or incorporated by reference in the
     Prospectus are independent public accountants within the meaning of the
     1933 Act and the 1933 Act Regulations.

         (vi) FINANCIAL STATEMENTS.  The financial statements and any supporting
     schedules of the Company included or incorporated by reference in the
     Registration Statement and the Prospectus present fairly the financial
     position of the Company as of the dates indicated and the results of its
     operations and cash flows for the periods specified; and, except as stated
     therein, said financial statements have been prepared in conformity with
     generally accepted accounting principles in the United States applied on a
     consistent basis; and any supporting schedules included in the Registration
     Statement present fairly the information required to be stated therein.

        (vii)  AUTHORIZATION AND VALIDITY OF THIS AGREEMENT, THE INDENTURE AND
     THE NOTES.  This Agreement has been duly authorized and, upon execution and
     delivery by the Agents, will be a valid and binding agreement of the
     Company; the Indenture has been duly authorized and constitutes a valid and
     binding obligation of the Company enforceable in accordance with its terms;
     the Notes have been duly and validly authorized for issuance, offer and
     sale pursuant to this Agreement and, when issued, authenticated and
     delivered pursuant to the provisions of this Agreement and the Indenture
     against payment of the consideration therefor specified in the Prospectus
     or pursuant to any Terms Agreement, the Notes will 

                                       5

<PAGE>

     constitute valid and legally binding obligations of the Company 
     enforceable in accordance with their terms; except as enforcement of the 
     Indenture and the Notes may be limited by bankruptcy, insolvency, 
     fraudulent conveyance, reorganization, moratorium and other similar laws 
     relating to or affecting the enforcement of creditors' rights generally 
     and general equitable principles; the Notes and the Indenture will be 
     substantially in the form heretofore delivered to the Agents and conform 
     in all material respects to all statements relating thereto contained in 
     the Prospectus; and the Notes will be entitled to the benefits provided 
     by the Indenture.

        (viii) MATERIAL CHANGES OR MATERIAL TRANSACTIONS.  Since the respective
     dates as of which information is given in the Registration Statement and
     the Prospectus, except as may otherwise be stated therein or contemplated
     thereby, there has been no material adverse change in the condition,
     financial or otherwise, of the Company, whether or not arising in the
     ordinary course of business.

        (ix)  NO CONFLICTS.  The execution and delivery of this Agreement and
     the Indenture and the consummation of the transactions contemplated herein,
     therein and pursuant to any applicable Terms Agreement have been duly
     authorized by all necessary corporate action and will not conflict with or
     constitute a breach of, or default under, or result in the creation or
     imposition of any lien, charge or encumbrance upon any property or assets
     of the Company pursuant to, any contract, indenture, mortgage, loan
     agreement, note, lease or other instrument to which the Company is a party
     or by which it may be bound or to which any of the property or assets of
     the Company is subject, nor will such action result in any violation of the
     Articles of Incorporation or By-laws, as restated or amended, of the
     Company or any law, administrative regulation or administrative or court
     order or decree.

         (x)  REGULATORY APPROVALS.  The Company has made all necessary filings
     and obtained all necessary consents, orders or approvals from the Federal
     Energy Regulatory Commission ("FERC") and the Public Service Commission of
     Wisconsin ("PSCW") in connection with the issuance and sale of the Notes,
     and no consent, approval, authorization, order or decree of any other court
     or governmental agency or body is required for the consummation by the
     Company of the transactions contemplated by this Agreement, except such as
     may be required under state securities ("Blue Sky") laws.

                                       6

     (b)  ADDITIONAL CERTIFICATIONS.  Any certificate signed by any director or
officer of the Company and delivered to the Agents or to counsel for the Agents
in connection with an offering of Notes or the sale of Notes to the Agents as
principal shall be deemed a representation and warranty by the Company to the
Agents as to the matters covered thereby on the date of such certificate and at
each Representation Date subsequent thereto.

SECTION 3.     SOLICITATIONS AS AGENTS; PURCHASES AS PRINCIPAL.

     (a)  SOLICITATIONS AS AGENTS.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, each Agent agrees, as the agent of the Company, to use its reasonable
efforts to solicit offers to purchase the Notes upon the terms and conditions
set forth herein and in the Prospectus.

     The Company reserves the right, in its sole discretion, to suspend
solicitation of purchases of Notes through any Agent, as agent, commencing at
any time for any period of time or permanently.  Upon receipt of instructions
from the Company, such Agent will forthwith suspend solicitation of purchases
from the Company until such time as the Company has advised such Agent that such
solicitation may be resumed.

     The Company agrees to pay each 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 Agents 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 Agents 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 $1,000 or any larger amount that is an integral multiple of
$1,000.  All Notes sold through any Agent as agent will be sold at 100% of their
principal amount unless otherwise agreed to by the Company and such Agent.

     (b)  PURCHASES AS PRINCIPAL.  Each sale of Notes to an Agent as 
principal shall be made in accordance with the terms contained herein and 
(unless the Company and such Agent shall otherwise agree) pursuant to a 
separate agreement which will provide for the sale of such Notes to, and the 
purchase and reoffering thereof by, 

                                       7

<PAGE>

such Agent.  Each such separate agreement (which may be an oral agreement) 
between such Agent and the Company is herein referred to as a "Terms 
Agreement".  Unless the context otherwise requires, each reference contained 
herein to "this Agreement" shall be deemed to include any applicable Terms 
Agreement between the Company and such Agent.  Each such Terms Agreement, 
whether oral or in writing, shall be with respect to such information (as 
applicable) as is specified in Exhibit A hereto.  Such 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 such 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 such Agent in the reoffering of the Notes, 
and such other provisions (including further terms of the Notes) as may be 
mutually agreed upon.  Such Agent may utilize a selling or dealer group in 
connection with the resale of the Notes purchased.  Such Terms Agreement 
shall also specify the requirements for the officers' certificate, opinions 
of counsel and comfort letter pursuant to Sections 8(b), 8(c) and 8(d) hereof.

     (c)  ADMINISTRATIVE PROCEDURES.  Administrative procedures with respect to
the sale of Notes shall be agreed upon from time to time by the Agents and the
Company (the "Procedures").  The Agents and the Company agree to perform the
respective duties and obligations specifically provided to be performed by them
in the Procedures.

SECTION 4.     COVENANTS OF THE COMPANY.

     The Company covenants with the Agents as follows:

     (a)  RULE 424(B) FILING.  Promptly following execution of this Agreement,
to cause the Prospectus, including as part thereof a prospectus supplement
relating to the Notes, to be filed with, or mailed for filing to, the SEC
pursuant to Rule 424(b) under the 1933 Act and the Company will promptly advise

     Indenture nor the issuance and sale of the Notes in accordance with the
     terms of this Agreement or Terms Agreements nor the consummation of the

hereof) at the date of any Terms Agreement and at the Settlement Date with
respect thereto as the case may be, contains or contained an untrue statement of
a material fact or omitted or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading or

     (e)  OFFICERS' CERTIFICATE.  The Company shall have furnished to the Agents
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(h), 5(i)and 5(j) hereof have been fulfilled.

     (f)  COMFORT LETTER.  On the date hereof, the Agents shall have received a
letter from PricewaterhouseCoopers LLP dated as of the date hereof and in form
and substance satisfactory to the Agents, 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 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 

                                       19

     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 Agents and the Company; and

          (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
     Agents, 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.

     (g)  OPINION OF AGENTS' COUNSEL.  Jones, Day, Reavis & Pogue, Chicago,
Illinois, as counsel for the Agents, shall have furnished to the Agents on 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 Agents may reasonably require.

     (h)  FERC AND PSCW ORDERS.  The orders of the FERC and PSCW referred to in
Section 2(a)(x) 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 

                                       20

Company's debt securities by Standard & Poor's Rating Service or Moody's 
Investors Service Inc.

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

     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
Agents, any applicable Terms Agreement) may be terminated by the Agents by
written 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(k) hereof,
the provisions concerning payment of expenses under Section 4(r) 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 

                                       21

<PAGE>

     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.

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

In case any of the conditions specified above in this Section 6 shall not have
been fulfilled on the date hereof, this Agreement may be terminated by the
Company by delivering written notice of termination to the Agents.  Any such
termination shall be without liability of any party to any other party except to
the extent provided in Section 4(r), and Section 9 hereof.

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

     Delivery of Notes sold through any 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, such Agent shall promptly notify the Company and deliver
the Note to the Company, and, if such Agent has theretofore paid the Company for
such Note, the Company will promptly return such funds to such Agent.  If such
failure occurred for any reason other than default by such Agent in the
performance of its obligations hereunder, the Company will reimburse such 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 each 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
an 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 such Agent
pursuant hereto are true and correct at the 

                                       22

<PAGE>

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 such 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 Agents 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 Statement, unless the Agents shall otherwise specify) or
(if required pursuant to the terms of a Terms Agreement) the Company sells Notes
to an Agent pursuant to a Terms Agreement, the Company shall furnish or cause to
be furnished to such 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
such Agent to the effect that the statements contained in the certificate
referred to in Section 5(e) hereof which was last furnished to such Agent are
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(e), 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 Notes or similar changes or solely for the inclusion of additional
financial information, and, unless the Agents shall otherwise specify, other
than by an amendment or supplement which relates exclusively to an offering of
securities other than 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 Agents shall otherwise
specify), or (if required pursuant to the terms of a Terms Agreement) the
Company 

                                       23

<PAGE>

sells Notes to an Agent pursuant to a Terms Agreement, the Company shall 
furnish or cause to be furnished forthwith to such Agent and to counsel to 
the Agents written opinion of Stafford, Rosenbaum, Rieser & Hansen, counsel 
to the Company, or other counsel satisfactory to such 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 such 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 Agents shall furnish 
such Agent with a letter to the effect that such 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 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 an Agent pursuant to a Terms Agreement,
the Company shall cause PricewaterhouseCoopers LLP forthwith to furnish such
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 such Agent, of the same tenor as the portions of the letter
referred to in clauses (i) and (ii) of Section 5(f) 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(f) 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, PricewaterhouseCoopers 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 such
Agent, such letter should cover such other information.

SECTION 9.  INDEMNIFICATION.

     (a) INDEMNIFICATION OF THE AGENTS.  The Company agrees to indemnify and
hold harmless each Agent and each person, if any, who controls such 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 required to be stated therein or 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 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 each
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 

                                       25

<PAGE>

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 such Agent, if a copy of the Prospectus provided to such 
Agent by the Company (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 such 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 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.  Each 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 such 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.

                                       26

<PAGE>

     The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
reasonably satisfactory to the indemnified party.  Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i)
counsel for the indemnified party concludes that the use of counsel chosen by
the indemnifying party to represent the indemnified party would present such
counsel with a conflict of interest, (ii) the actual or potential defendants in,
or targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have been advised by counsel
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after notice of the institution of such action or
(iv) the indemnifying party shall authorize the indemnified party to employ
separate counsel at the expense of the indemnifying party.

     (d)  CONTRIBUTION.  If the indemnification provided for in this Section is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to herein, then each indemnifying party,
in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and each Agent on the
other from the sale to or through each Agent of the Notes or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and of each Agent on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations; provided, however, that in no
case shall any Agent be responsible for any amount in excess of the total
underwriting discounts and commission received by such Agent in connection with
the sale of the Notes to or through such Agent.  

                                       27

<PAGE>

The relative benefits received by the Company on the one hand and each Agent 
on the other in connection with the sale of the Notes shall be deemed to be 
in the same proportion as the total commissions and underwriting discounts 
received by such Agent to the date of such liability bear to the total sales 
price from the sale of Notes to or through such Agent to the date of such 
liability.  The relative fault of the Company on the one hand and of each 
Agent on the other shall be determined by reference to, among other things, 
whether the untrue or alleged untrue statement of a material fact or the 
omission or alleged omission to state a material fact relates to information 
supplied by the Company or by such Agent and the parties' relative intent, 
knowledge, access to information and opportunity to correct or prevent such 
statement or omission.

     The Company and the Agents agree that it would not be just and equitable if
contribution pursuant to this Section were determined by pro rata allocation or
by any other method of allocation which does not take account of the
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section, 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 Agent
within the meaning of Section 15 of the 1933 Act shall have the same rights to
contribution as such 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 an Agent or any controlling person of such
Agent, or by or on behalf of the Company, and shall survive each delivery of and
payment for any of the Notes.

                                       28

<PAGE>

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 Agents upon the giving of 30 days' written notice of such termination to
the other party hereto.

     (b)  TERMINATION OF A TERMS AGREEMENT.  An 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, of the Company, whether or not arising in the ordinary
course of business, or (ii) if there shall have occurred any outbreak or
escalation of major hostilities in which the United States is involved or any
other substantial national or international calamity or crisis the effect of
which is such as to make it, in the judgment of such Agent, impracticable or
inadvisable to market Notes or enforce contracts for the sale of Notes, or (iii)
if trading in any securities of the Company has been suspended by the SEC or a
national securities exchange or in the NASDAQ National Market, or if trading
generally on 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 said exchange 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 statistical rating organization" (as
defined for purposes of Rule 436(g) of the 1933 Act) 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 organization 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 such Agent's attention any facts that would cause such 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) an 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) an Agent shall own
any Notes purchased pursuant to a Terms Agreement with the intention of

                                       29

<PAGE>

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(r)
hereof, the indemnity and contribution agreements set forth in Section 9 hereof,
and the provisions of Sections 4(r), 10 and 14 hereof shall remain in effect.

SECTION 12.    NOTICES.

     Unless otherwise provided herein, all notices required under the terms and
provisions hereof shall be in writing, either delivered by hand, by mail or by

Dear Sirs:

Schedule I hereto (the "Underwriters"), for whom you are acting as
representatives ("Representatives"), _____________ shares of the common stock,

          The Company also proposes to issue and sell to the several
Underwriters not more than an additional ______ shares of its common stock, $1
par value (the "Additional Shares"), if and to the extent that the
Representatives shall have determined to exercise, on behalf of the
Underwriters, the right to purchase such shares of common stock granted to the
Underwriters in Section 2.  The Firm Shares and the Additional Shares are
hereinafter collectively referred to as the "Shares".  The shares of the common
stock, $1 par value, of the Company to be outstanding after giving effect to the
sales contemplated hereby are hereinafter referred to as the "Common Stock".

     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 Shares, 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.  As used in this Agreement, (i) "Registration Statement" means such
registration statement, as 

                                      

<PAGE>

amended or supplemented to the date hereof; (ii) "Preliminary Prospectus" 
means each prospectus (including all documents incorporated therein by 
reference) specifically relating to the Shares included in the Registration 
Statement before it became effective under the 1933 Act, including any 
prospectus filed with 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 
Shares included in the Registration Statement; and (iv) "Prospectus" means 
the Basic Prospectus together with any prospectus amendment or supplement 
(including in each case all documents incorporated therein by reference) 
specifically relating to the Shares, as filed with, or mailed for filing to, 
the SEC pursuant to paragraph Rule 424(b) of the 1933 Act Regulations.

SECTION 1.     REPRESENTATIONS AND WARRANTIES.

     (a)  The Company represents and warrants to each Underwriter 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 Wisconsin 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 not required to be
     qualified as a foreign corporation to transact business in any other
     jurisdiction.

         (ii)  SUBSIDIARIES.  The Company has no significant subsidiaries, as
     "significant subsidiary" is defined in Rule 405 of the 1933 Act
     Regulations.
     
         (iii) REGISTRATION STATEMENT AND PROSPECTUS.  At the time the
     Registration Statement became effective, the Registration Statement
     complied, and on the date hereof complies, in all material respects, with
     the requirements of the 1933 Act and the 1933 Act Regulations.  The
     Registration Statement, at the time it became effective did not, on the
     date hereof does not, and at all times during the period specified in
     Section 3(k) hereof 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 at all times during the period
     specified in Section 3(K) 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 

                                      2

<PAGE>

     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 any Underwriter through the Representatives 
     expressly for use in the Registration Statement or Prospectus.

        (iv) 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
     Securities Exchange Act of 1934 ("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 3(k) 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.

          (v) ACCOUNTANTS.  The accountants who issued their reports on the
     financial statements included or incorporated by reference in the
     Prospectus are independent public accountants within the meaning of the
     1933 Act and the 1933 Act Regulations.

         (vi) FINANCIAL STATEMENTS.  The financial statements and any supporting
     schedules of the Company included or incorporated by reference in the
     Registration Statement and the Prospectus present fairly the financial
     position of the Company as of the dates indicated and the results of its
     operations and cash flows for the periods specified; and, except as stated
     therein, said financial statements have been prepared in conformity with
     generally accepted accounting principles in the United States applied on a
     consistent basis; and any supporting schedules included in the Registration
     Statement present fairly the information required to be stated therein.

        (vii)  AUTHORIZATION AND VALIDITY OF THIS AGREEMENT.  This Agreement has
     been duly authorized and, upon execution and delivery by the
     Representatives on behalf of the Underwriters, will be a valid and binding
     agreement of the Company.

       (viii)  The authorized capital stock of the Company conforms to the
     description thereof contained in the Prospectus.

     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 Representatives and the Company; and

          (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 

                                      15

     incorporated by reference in the Registration Statement and Prospectus 
     and which are specified by the Representatives, 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.

     (g)  OPINION OF UNDERWRITERS' COUNSEL.  Jones, Day, Reavis & Pogue,
Chicago, Illinois, as counsel for the Underwriters, shall have furnished to the
Representatives on the Closing Date such opinions with respect to the validity
of the Shares and with respect to the Registration Statement, the Prospectus,
and other related matters as the Representatives may reasonably require.

     (h)  FERC AND PSCW ORDERS.  The order of the PSCW referred to in Section
1(a)(x) 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)  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),
of the Company, whether or not arising in the ordinary course of business,
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.

     (j)  OTHER DOCUMENTS.  Counsel to the Underwriters 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 Shares 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 Company in connection with the issuance and sale of
Shares as herein contemplated shall be satisfactory in form and substance to the
Representatives and to counsel to the Underwriters.

     If any condition specified in this Section 4 shall not have been fulfilled
when and as required to be fulfilled, this Agreement  may be terminated by the
Representatives by written notice to the Company 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 3(h) hereof,
the provisions concerning payment of expenses 


                                      16

<PAGE>

under Section 3(m) hereof, the indemnity and contribution agreement set forth 
in Section 6 hereof, the provisions concerning the payment of expenses in 
Section 8 hereof and the provisions set forth under "Parties" of Section 12 
hereof shall remain in effect.

SECTION 5.  CONDITIONS TO THE OBLIGATIONS OF THE COMPANY.

     The obligations of the Company to sell and deliver the Shares 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.

          (b)  PSCW ORDERS.  The order of the PSCW referred to in Section
     (1)(a)(x) hereof shall be in full force and effect and no proceeding to
     suspend the effectiveness of either such order shall be pending or
     threatened.

In case any of the conditions specified above in this Section 5 shall not have
been fulfilled on the date hereof, this Agreement may be terminated by the
Company by delivering written notice of termination to the Representatives.  Any
such termination shall be without liability of any party to any other party
except to the extent provided in Section 3(m), and Section 6 hereof.

SECTION 6.  INDEMNIFICATION.

     (a) INDEMNIFICATION OF THE UNDERWRITERS. The Company agrees 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 required to be stated therein or 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

                                      17

<PAGE>

     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 6(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 any
Underwriter through the Representatives 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 Underwriter from whom the person asserting any such
losses, liabilities, claims, damages or expenses purchased Shares, or any person
controlling such Underwriter, 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) is provided to the Underwriter but 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
Shares 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 

                                      18

<PAGE>

document which is incorporated or deemed to be incorporated by reference in 
the Prospectus.

     (b)  INDEMNIFICATION OF THE COMPANY.  Each Underwriter 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 such
Underwriter through the Representatives 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.

     The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
reasonably satisfactory to the indemnified party.  Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i)
counsel for the indemnified party concludes that the use of counsel chosen by
the indemnifying party to represent the 

                                      19

<PAGE>


indemnified party would present such counsel with a conflict of interest, 
(ii) the actual or potential defendants in, or targets of, any such action 
include both the indemnified party and the indemnifying party and the 
indemnified party shall have been advised by counsel that there may be legal 
defenses available to it and/or other indemnified parties which are different 
from or additional to those available to the indemnifying party, (iii) the 
indemnifying party shall not have employed counsel reasonably satisfactory to 
the indemnified party to represent the indemnified party within a reasonable 
time after notice of the institution of such action or (iv) the indemnifying 
party shall authorize the indemnified party to employ separate counsel at the 
expense of the indemnifying party.

     (d)  CONTRIBUTION.  If the indemnification provided for in this Section is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to herein, then each indemnifying party,
in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and each Agent on the
other from the sale to or through each Agent of the Notes or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company on
the one hand and of each Agent on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations; provided, however, that in no
case shall any Agent be responsible for any amount in excess of the total
underwriting discounts and commission received by such Agent in connection with
the sale of the Notes to or through such Agent.  The relative benefits received
by the Company on the one hand and each Agent on the other in connection with
the sale of the Notes shall be deemed to be in the same proportion as the total
commissions and underwriting discounts received by such Agent to the date of
such liability bear to the total sales price from the sale of Notes to or
through such Agent to the date of such liability.  The relative fault of the
Company on the one hand and of each Agent on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by such Agent and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

                                      20

<PAGE>

     The Company and the Agents agree that it would not be just and equitable if
contribution pursuant to this Section were determined by pro rata allocation or
by any other method of allocation which does not take account of the
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section, 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 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 7.     TERMINATION.  

     The Representatives may terminate this Agreement, immediately upon notice
to the Company, at any time prior to the Closing Date (i) if there has been,
since the date of this 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, of the Company, whether or not arising
in the ordinary course of business, or (ii) if there shall have occurred any
outbreak or escalation of major hostilities in which the United States is
involved or any other substantial national or international calamity or crisis
the effect of which is such as to make it, in the judgment of the
Representatives, impracticable or inadvisable to market the Shares, or (iii) if
trading in any securities of the Company has been suspended by the SEC or a
national securities exchange or in the NASDAQ National Market, or if trading
generally on 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 said exchange 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 there shall have
come to the attention of the Representatives any facts that would cause the
Representatives to believe that the 

                                      21

<PAGE>

Prospectus, at the Closing 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 Closing 
Date, not misleading.

SECTION 8.     PAYMENT OF EXPENSES IN CERTAIN CIRCUMSTANCES.  

     If the purchase of the Shares by the Underwriters is not consummated for
any reason other than a default by one or more of the Underwriters, the Company
shall remain responsible for the expenses to be paid or reimbursed by it
pursuant to Section 3(m) hereof, the respective obligations of the Company and
the Underwriters pursuant to Section 6 hereof shall remain in effect, and the
Company will reimburse the Representatives for the reasonable out-of-pocket
expenses of the Underwriters, not exceeding $10,000, and for the fee and
disbursements of Jones, Day, Reavis & Pogue, Chicago, Illinois, the Underwriters
agreeing to pay such expenses, fee and disbursements in any other event.  In no
event will the Company be liable to any of the Underwriters for damages on
account of loss of anticipated profits.

SECTION 9.     DEFAULT BY UNDERWRITERS.  

     If one or more of the Underwriters shall fail at the Closing Date to
purchase the Shares which it or they are obligated to purchase under this
Agreement (Defaulted Shares"), the Representatives 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 Shares in such amounts as may be agreed upon and upon the terms
herein set forth; if, however, the Representatives shall not have completed such
arrangements within such 24-hour period, then:

          (a)  if the amount of Defaulted Shares does not exceed 10% of the
amount of the Shares, 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 hereunder bear to the
underwriting obligations of all non-defaulting Underwriters, or

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

          No action taken pursuant to this Section 9 shall relieve any
defaulting Underwriter from liability in respect of its default.

                                      22

<PAGE>

          In the event of any such default which does not result in a
termination of this Agreement, either the Representatives or the Company shall
have the right to postpone the Closing 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 10.    NOTICES.

     Unless otherwise provided herein, all notices required under the terms and

hereunder and shall never be entitled to the benefits of this Indenture.

    SECTION 2.06.  EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES.

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

                                     34

<PAGE>

shall authenticate and deliver in exchange therefor the Note or Notes which 
the Noteholder making the exchange shall be entitled to receive.

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

    (c)  All Notes presented for registration of transfer  or for exchange, 
redemption or payment shall (if so required by the Company) be duly endorsed 
by, or be accompanied by a written instrument or instruments of transfer in 
form satisfactory to the Company and the Trustee duly executed by, the Holder 
or the attorney of such Holder duly authorized in writing.

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

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

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

                                     35

    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 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 

                                     36

<PAGE>

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 

                                     37

<PAGE>

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 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 

                                     38

<PAGE>

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:  "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."

    (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 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 

                                     39

<PAGE>


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 denominations 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 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.

                                     40

<PAGE>


    (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 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.

                                     41

<PAGE>


          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 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

                                     42

<PAGE>

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 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.

                                     43

<PAGE>


    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 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 

                                     44

<PAGE>


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

    SECTION 3.06.  RESET NOTES.  

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

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

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

to apply such money or U.S. Government Obligations in accordance with Section 
5.01; PROVIDED, HOWEVER, that if the Company has made any payment of 
principal of or any premium or interest on any Notes because of the

     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, by 
     registered or certified mail, to the Company by the Trustee or to the 
     Company and the Trustee by the Holders of at least 25% in aggregate 
     principal amount of the Notes then outstanding, a written notice 
     specifying such default or defaults and stating that such notice is a 
     "Notice of Default" hereunder; or 

         (5)  the entry against the Company or any Subsidiary of the Company 
     of one or more judgments, decrees or orders by a court having

     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 and there has been 
     given, by registered or certified mail, to the Company by the Trustee or 
     to the Company and the Trustee by the Holders of at least 25% in 
     aggregate principal amount of the Notes then outstanding, a written 
     notice specifying such entry and continuance of such judgment, decree or 
     order and stating that such notice is a "Notice of Default" hereunder; 
     or

     Company by a court having jurisdiction in the premises in an involuntary 
     case under the federal bankruptcy laws, as now or hereafter constituted,

                                      56

<PAGE>

     or state bankruptcy, insolvency or other similar law, or a decree or order 
     adjudging the Company a bankrupt or insolvent, or approving as properly 
     filed a petition seeking reorganization, arrangement, adjustment or 
     composition of or in respect of the Company under any applicable federal 
     or state law, or appointing a receiver, liquidator, assignee, custodian, 
     trustee, sequestrator (or other similar official) of the Company or of 
     any substantial part of its property, or ordering the winding up or 
     liquidation of its affairs, and the continuance of any such decree or 
     order unstayed and in effect for a period of 60 consecutive days; or 

         (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 aggregate 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 writing to 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


                                      57

<PAGE>

         (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 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 
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 


                                      58

<PAGE>

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 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 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 


                                      59

<PAGE>

         (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 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 


                                      60

<PAGE>

     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 


                                      61

<PAGE>

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.

    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 


                                      62

<PAGE>

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 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 


                                      63

<PAGE>

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.

                                     ARTICLE NINE

                                CONCERNING THE TRUSTEE

    SECTION 9.01.  CERTAIN DUTIES AND RESPONSIBILITIES.

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

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

         (2)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the 


                                      64

<PAGE>

     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 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; 


                                      65

<PAGE>

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;

    (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 


                                      66

<PAGE>

     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 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 


                                      67

<PAGE>

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 such compensation that the Company and
     Trustee shall from time to time agree in writing 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.


                                      68
<PAGE>

          (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 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;

                                         69

<PAGE>


          (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 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 

                                         70

<PAGE>

     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
     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

                                         71

<PAGE>

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 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.

     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.

                                         72

     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 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

     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:

          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;

                                         73

<PAGE>

             (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
     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 Columbus, Ohio 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 

                                         74

<PAGE>


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 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 

                                         75

<PAGE>


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 the
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, 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 

                                         76

<PAGE>


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 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:

                                         77

<PAGE>


          (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
     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 


                                         78

<PAGE>

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

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

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

                                         79

<PAGE>

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

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

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

          (2)  advances authorized by a receivership or bankruptcy court of
     competent jurisdiction or by this Indenture, for the purposes of preserving
     any property which shall at any time be subject to the lien of this
     Indenture or of discharging tax liens or other prior liens or encumbrances
     thereon, if notice of such advances and of the circumstances surrounding
     the making thereof is given to the Holders at the time and in the manner
     provided in this Indenture;

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

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

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

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

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

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

                                         80

<PAGE>

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

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

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

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

          (6)  the term "Federal Bankruptcy Act" means the Bankruptcy Act or

          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 


                                         81

<PAGE>


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 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 


                                         82

<PAGE>

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:

                       Trustee's Certificate of Authentication

          This is one of the Notes referred to in the within-mentioned
     Indenture.

                              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 

                                       83

<PAGE>

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 

                                       84

<PAGE>


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.

Noteholders duly called pursuant to Section 11.02 or 11.03, the presence of

the Holders of a majority in aggregate principal amount of the Notes present in
person or by proxy at the meeting, whether or not constituting a quorum, and the
meeting may be held as so adjourned without further notice.

          SECTION 11.06.  VOTING.  The vote upon any resolution submitted to any
meeting of Noteholders shall be by written ballots on which shall be subscribed

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 in duplicate of all votes cast at the 
meeting.  A record in duplicate of the proceedings of each meeting of 
Noteholders 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 11.02.  The record 
shall show the principal amount of the Notes voting in favor of or against 
any resolution.  The record shall be signed and verified by the affidavits of 
the permanent chairman and secretary of the meeting and one of the duplicates 
shall be delivered to the Company and the other to the Trustee to be

     part of the Company to be performed or observed;

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

          (3)  if, as a result of such consolidation, merger, 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 this Indenture without making effective
     provision whereby the Notes then outstanding and any other indebtedness of
     the Company then entitled thereto will be equally and ratably secured with
     any and all indebtedness and obligations secured thereby, the Company or
     the successor corporation or Person, as the case may be, will take such
     action as will be necessary effectively to secure all Notes equally and
     ratably with (or prior to) all indebtedness secured thereby; and

     Certificate and an Opinion of Counsel each stating that such
     consolidation, merger, conveyance, transfer or lease and such
     supplemental indenture comply with this Article Twelve and that all
     conditions precedent herein provided for relating to such
     consolidation, merger, conveyance or transfer have been complied with.

consolidation or merger, or any conveyance, transfer or lease as an entirety in
accordance with Section 12.01, the successor corporation formed by such
consolidation or into which the Company is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor corporation had been named as the Company
herein; PROVIDED, HOWEVER, that no such conveyance or transfer shall have the
effect of releasing the Person named as the "Company" in the first paragraph of
this Indenture or any successor corporation which shall theretofore have become
such in the manner prescribed in this Article Twelve from its liability as
obligor and maker on any of the Notes.

          (2) to change or eliminate any of the provisions of this Indenture;

          (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 herein; 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

          (b)  The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer and assignment of any property thereunder, but the Trustee
shall not be obligated to enter into any such supplemental indenture which
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
Section 13.02.

          SECTION 13.02.  SUPPLEMENTAL INDENTURES WITH CONSENT OF NOTEHOLDERS.

          (a)  With the consent (evidenced as provided in Section 10.01) of the

then outstanding that would be affected by the particular supplemental
indenture, the Company, when authorized by Board Resolution, and the Trustee may
from time to time and at any time 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 of any
supplemental indenture or of modifying in any manner the rights of the
Noteholders; PROVIDED, HOWEVER, that no such supplemental indenture shall:

          (1)  change the Stated Maturity of any Note; or reduce the rate

     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

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

supplemental indenture, but it shall be sufficient if such consent shall approve
the substance thereof.

any supplemental indenture pursuant to this Section 13.02, the Company shall

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

                                   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 __________,
1998 (herein called the "Indenture") between the Company and Bank One, N.A., 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 rates, 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 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. 

                                        A-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 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 

                                        A-5
<PAGE>

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
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 


                                        A-6
<PAGE>

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 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 denominations as requested

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

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

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.

redemption, shall be payable to the Person to whom principal shall be 
payable.  Except as otherwise provided in the Indenture, any such interest 
not so punctually paid or duly provided for will forthwith cease to be 
payable to the Holder on such Record Date and shall be paid to the Person in 
whose name this Note is registered at the close of business on a Record Date 
for the payment of such defaulted interest to be fixed by the Company, notice 
whereof shall be given to Noteholders not less than fifteen days prior to 
such Record Date.  Payment of the principal of and any premium and interest

                                   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 __________,
1998 (herein called the "Indenture") between the Company and Bank One, N.A., 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 rates, 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 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.

<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 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 

                                        B-5
<PAGE>

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
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 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 a written
instrument of transfer in form satisfactory to the Company and the note
registrar duly executed by, the Holder hereof or the attorney of such Holder
duly authorized in writing,  the Company shall execute and register or cause to
be registered and the Trustee shall authenticate and make available for
delivery, in the name of the transferee or transferees one or more new Notes of
any authorized denominations and of a like aggregate principal amount 

                                        B-7
<PAGE>

and Stated Maturity and having the same terms and Original Issue Date.

          No service charge will be made for any such exchange or registration
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
not defined in this Note shall have the meanings assigned to them in the
Indenture.

          Madison Gas and Electric Company, a Wisconsin corporation (herein
called the "Company", which term includes any successor Person under the
Indenture referred to on the reverse hereof), for value received, hereby
promises to pay to

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

10:30 A.M., New 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, by wire transfer into the account specified by the Depositary; PROVIDED, 
HOWEVER, that as a condition to the payment at the Maturity date of any part 
of the principal and any applicable premium of this Global Note, the 
Depositary shall surrender, or cause to be surrendered, this Global Note to 
the Trustee.  The Company will pay any administrative costs imposed by banks 
in connection with making payments by wire transfer, but not any tax, 
assessment or governmental charge imposed on the Holder of this Note.

          Under certain circumstances, this Global Note is exchangeable in whole
or from time to time in part for a definitive individual Note or Notes, with the
same Original Issue Date or Dates, Maturity date, Interest Rate and redemption
and other provisions as provided herein or in the Indenture.

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

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

          IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

                                   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 __________,
1998 (herein called the "Indenture") between the Company and Bank One, N.A., 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 rates, 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, 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.

<PAGE>

          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 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.

<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.

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


                                     C-6

<PAGE>

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 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 denominations as requested
by such Person in aggregate principal amount equal to and in exchange for the
beneficial interest of such Person in this Global Note, and (2) to such
Depositary a new Global Note of like tenor and terms and in a denomination equal
to the difference, if any, between the principal amount of this Global Note and
the aggregate principal amount of Notes delivered to Holders thereof.

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

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

          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.

called the "Company", which term includes any successor Person under the
Indenture referred to on the reverse hereof), for value received, hereby
promises to pay to

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

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

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

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

                           MADISON GAS AND ELECTRIC 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
__________, 1998 (herein called the "Indenture") between the Company and Bank
One, N.A., 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 rates, 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 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 


                                     D-4

<PAGE>

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 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 


                                     D-5

<PAGE>

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.

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

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Notes will have any right to institute any proceeding with respect
to the Indenture or for any remedy thereunder, unless such Holder shall have
previously given to the Trustee written notice of a continuing default with
respect to the Notes, the Holders of not less than a majority in aggregate
principal amount of the Notes then outstanding shall have made 


                                     D-6

<PAGE>

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 a written
instrument of transfer in form satisfactory to the Company and the note
registrar duly executed by, the Holder hereof or the attorney of such Holder
duly authorized in writing,  the Company shall execute and register or cause to
be registered and the Trustee shall authenticate and make available for
delivery, in the name of the transferee or transferees one or more new Notes of
any authorized denominations and of a like aggregate principal amount and Stated
Maturity and having the same terms and Original Issue Date.

          No service charge will be made for any such exchange or registration
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

                        INTEREST CALCULATION AGENCY AGREEMENT


          INTEREST CALCULATION AGENCY AGREEMENT between MADISON GAS AND ELECTRIC
COMPANY (the "Issuer") and ____________________ ("_____ _______") dated as of
________ __, 1998.

                                PRELIMINARY STATEMENT

          1.   The Issuer proposes to issue and sell its Medium-Term Notes due
from 9 Months to 30 Years from Date of Issue (the "Notes") from time to time
under, and pursuant to, the terms of an Indenture, dated as of ________ _, 1998
between the Company and ____________, as Trustee (in such capacity, the
"Trustee"), (the "Indenture").  Capitalized terms not otherwise defined herein
shall have the meanings assigned to them in the Indenture and if not defined
therein then as defined in the Prospectus and Prospectus Supplement relating to
the Notes.

          2.   The Issuer desires to appoint an agent of the Issuer to calculate
the base rates applicable to those Notes on which interest is to accrue, at any
time, at a variable or floating rate  ("Floating Rate Notes"), determined by
references to the Commercial Paper Rate, LIBOR, the Prime Rate, the Treasury
Rate or other interest rate basis as is set forth in a pricing supplement
(collectively, the "Base Rates") as are specified and described in the Floating
Rate Notes.

          NOW, THEREFORE, the Issuer and _____________ hereby agree as follows:

          Section 1.  APPOINTMENT OF CALCULATION AGENT.  The Issuer hereby
appoints _____________ as Calculation Agent (in such capacity, the "Calculation
Agent") of the Issuer with respect to any Floating Rate Notes to be issued by
the Issuer under and pursuant to the terms of the Indenture, and the Calculation
Agent hereby accepts its obligations as set forth in this Agreement upon the
terms and conditions set forth herein.

          SECTION 2.  CALCULATION OF BASE RATES.  The calculation date (the
"Calculation Date") for each applicable Interest Determination Date for any Note
shall be the earlier of (i) the tenth calendar day after such Interest
Determination Date or, if any such day is not a Business Day, the next
succeeding Business Day and (ii) the Business Day preceding the applicable
Interest Payment Date or date of Maturity, as the case may be.  The Calculation
Agent shall notify the Issuer and the Trustee of the applicable interest rate on
or prior to each such Calculation Date.



<PAGE>

If at any time the Calculation Agent is not also acting as Trustee under the
Indenture, the Issuer shall, upon the issuance of each Floating Rate Note having
a different Base Rate or different Interest Determination Dates than the Base
Rate or Interest Determination Dates for any prior Floating Rate Note, notify
such Calculation Agent of such Interest Determination Dates and the applicable
interest rate base(s) or formula for such Floating Rate Note.

          SECTION 3.  NEW BASE RATES.  If the Issuer proposes to issue Floating
Rate Notes whose interest rate will be determined on a basis or formula not
referred to above (a "New Base Rate"), the Issuer shall give a description of
such New Base Rate to the Calculation Agent.  The Calculation Agent shall
determine if it is able and willing to calculate the New Base Rate and upon its
agreement in writing to do so the term "Base Rate" shall be deemed to include
the New Base Rate.  If the Calculation Agent notifies the Issuer that it is not
able or willing to calculate the New Base Rate, or that it is only willing to do
so on the basis of an increase of its fees not acceptable to the Issuer, the
Calculation Agent shall have no responsibility with respect to such New Base
Rate and the Issuer shall appoint a different calculation agent to determine the
New Base Rate.

          SECTION 4.  FEES AND EXPENSES.  The Calculation Agent shall be
entitled to such compensation for its services under this Agreement as may be
agreed upon with the Issuer, and the Issuer shall pay such compensation and
shall reimburse the Calculation Agent for all reasonable expenses, disbursements
and advances incurred or made by the Calculation Agent in connection with the
services rendered by it under this Agreement, including reasonable legal fees
and expenses, upon receiving an accounting therefor from the Calculation Agent.

          SECTION 5.  RIGHTS AND LIABILITIES OF CALCULATION AGENT.  The
Calculation Agent shall incur no liability for, or in respect of, any action
taken, omitted to be taken or suffered by it in reliance upon any Floating Rate
Note, certificate, affidavit, instruction, notice, request, direction, order,
statement or other paper, document or communication reasonably believed by it to
be genuine.  Any certificate, affidavit, instruction, notice, request,
direction, order, statement or other communication from the Issuer made or given
by it and sent, delivered or directed to the Calculation Agent under, pursuant
to or as permitted by any provision of this Agreement shall be sufficient for
purposes of this Agreement if such communication is in writing and signed by any
officer of the Issuer.  The Calculation Agent may consult with counsel
satisfactory to it and the opinion of such counsel shall


                                         -2-
<PAGE>

constitute full and complete authorization and protection of the Calculation
Agent with respect to any action taken, omitted to be taken or suffered by it
hereunder in good faith and in accordance with and in reliance upon the opinion
of such counsel.  In acting under this Agreement, the Calculation Agent (in its
capacity as such) does not assume any obligation towards, or any relationship of
agency or trust for or with the holders of the Notes.

          SECTION 6.  RIGHT OF CALCULATION AGENT TO OWN FLOATING RATE NOTES.
The Calculation Agent may act as Trustee under the Indenture and it and its
officers, employees and shareholders may become owners of, or acquire any
interests in, Floating Rate Notes, with the same rights as if the Calculation
Agent were not the Calculation Agent, and it may engage in, or have an interest
in, any financial or other transaction with the Issuer as if the Calculation
Agent were not the Calculation Agent.

          SECTION 7.  DUTIES OF CALCULATION AGENT.  The Calculation Agent shall
be obligated only to perform such duties as are specifically set forth herein
and no other duties or obligations on the part of the Calculation Agent, in its
capacity as such, shall be implied by this Agreement.

          SECTION 8.  TERMINATION, RESIGNATION OR REMOVAL OF CALCULATION AGENT.
The Calculation Agent may at any time terminate this Agreement by giving no less
than 90 days written notice to the Issuer unless the Issuer consents in writing
to a shorter time.  Upon receipt of notice of termination by the Calculation
Agent, the Issuer agrees promptly to appoint a successor Calculation Agent.  The
Issuer may terminate this Agreement at any time by giving written notice to the
Calculation Agent and specifying the date when the termination shall become
effective; provided, however, that no termination by the Calculation Agent or by
the Issuer shall become effective prior to the date of the appointment by the
Issuer, as provided in Section 9 hereof, of a successor Calculation Agent and
the acceptance of such appointment by such successor Calculation Agent.  If an
instrument of acceptance by a successor Calculation Agent shall not have been
delivered to the Calculation Agent within 30 days after the giving of such
notice of resignation, the resigning Calculation Agent may petition any court of
competent jurisdiction for the appointment of a successor Calculation Agent.
Upon termination by either party pursuant to the provisions of this Section, the
Calculation Agent shall be entitled to the payment of any compensation owed to
it by the Issuer hereunder and to the reimbursement of reasonable expenses,
disbursements and advances incurred or made by the Calculation Agent in
connection with the services rendered by it hereunder, as provided by Section 4
hereof.


                                         -3-
<PAGE>

          SECTION 9.  APPOINTMENT OF SUCCESSOR CALCULATION AGENT.  Any successor
Calculation Agent appointed by the Issuer or by a court following termination of
this Agreement pursuant to the provisions of Section 8 hereof shall execute and
deliver to the Calculation Agent and to the Issuer an instrument accepting such
appointment, and thereupon such successor Calculation Agent shall, without any
further act or instrument become vested with all the rights, immunities, duties
and obligations of the Calculation Agent, with like effect as if originally
named as Calculation Agent hereunder, and the resigning Calculation Agent shall
thereupon be obligated to transfer and deliver, and such successor Calculation
Agent shall be entitled to receive and accept, copies of any available records
maintained by the resigning Calculation Agent in connection with the performance
of its obligations hereunder.

          SECTION 10.  INDEMNIFICATION.  The Issuer shall indemnity and hold
harmless the Calculation Agent, its officers and employees from and against all
actions, claims, damages, liabilities, losses and expenses (including reasonable
legal fees and expenses) relating to or arising out of actions or omissions in
any capacity hereunder, except actions, claims, damages, liabilities, losses and
expenses relating to or arising from the negligence or willful misconduct of the
Calculation Agent, its officers or employees.  The Calculation Agent shall
indemnity and hold harmless the Issuer, its officers and employees from and
against all actions, claims, damages, liabilities, losses and expenses
(including reasonable legal fees and expenses) relating to or arising from the
negligence or willful misconduct of the Calculation Agent, its officers or
employees.  This Section 10 shall survive the payment in full of all obligations
under the Notes, whether by redemption, repayment or otherwise.

          SECTION 11.  MERGER, CONSOLIDATION OR SALE OF BUSINESS BY CALCULATION
AGENT.  Any corporation into which the Calculation Agent may be merged,
converted or consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Calculation Agent may be a party, or
any corporation to which the Calculation Agent may sell or otherwise transfer
all or substantially all of its corporate trust business, shall, to the extent
permitted by applicable law, become the Calculation Agent under this Agreement
without the execution of any document or any further act by the parties hereto.

          SECTION 12.  NOTICES.  Any notice or other communication given
hereunder shall be delivered in person, sent by letter, telecopy or communicated

July 20, 1998

Madison Gas & Electric Company
133 South Blair Street
P.O. Box 1231
Madison, Wisconsin 53701-1231

Subject:  Madison Gas and Electric Company Registration Statement on Form S-3

Ladies and Gentlemen:

I am Senior Vice President - Administration and Secretary of Madison Gas and
Electric Company (the "Company") and an attorney licensed to practice law in the
State of Wisconsin. In that connection, I am familiar with the filing of a
Registration Statement on Form S-3 (the "Registration Statement") relating to
shares of Common Stock, par value $1 per share, of the Company ("Common Stock")
which may be purchased under the Company's Investors Plus Plan (the "Plan").

I am also familiar with the Restated Articles of Incorporation and the By-Laws
of the Company and all amendments thereto and resolutions of the Board of
Directors of the Company relating to the Plan and the Registration Statement.

In this connection, I have examined or caused to be examined and am familiar
with originals or copies, certified or otherwise identified to my satisfaction,
of all such records of the Company and others as I have deemed necessary or
appropriate as a basis for the opinions set forth herein. In my examination, I
have assumed the genuineness of all signatures, the authenticity of all
documents submitted to me as certified or photostatic copies, and the
authenticity of the originals of such latter documents. As to any facts material
to the opinion expressed herein which were not independently established or
verified by me, I have relied upon statements and representations of certain
officers and other representatives of the Company and others.

Based upon the foregoing, I am of the opinion that:

1.   The Company is duly incorporated and validly existing under the laws of the
     State of Wisconsin.

2.   Any shares of Common Stock purchased by an independent agent selected by
     the Company on the open market for the consideration provided in the Plan
     are legally issued, fully paid and non-assessable, except to the extent
     that such shares are assessable as provided in Section 180.0622 of the
     Wisconsin Business Corporation Law.

3.   If the Company's Board of Directors, or a duly authorized committee
     thereof, and the Public Service Commission of the State of Wisconsin
     authorize the issuance of authorized and unissued shares of Common Stock
     for the consideration (but not less than the par value) provided in the
     Plan, such shares will, when certificates representing such shares shall
     have been duly executed, countersigned and registered, and duly delivered
     against the receipt by the Company of the consideration provided in the
     Plan, be legally issued, fully paid and non-assessable, except to the
     extent that such shares are assessable as provided in Section 180.0622 of
     the Wisconsin Business Corporation Law.

4.   If the Company legally and validly reacquires issued and outstanding shares
     of Common Stock and thereafter, pursuant to the authorization by the Board
     of Directors or a duly authorized committee thereof, resells such issued
     but not outstanding shares for the consideration (but not less than par
     value) provided in the Plan, such shares will upon delivery against receipt
     by the Company of the consideration provided in the Plan, be legally
     issued, fully paid and non-assessable, except to the extent that such
     shares are assessable as provided in Section 180.0622 of the Wisconsin
     Business Corporation Law.

I do not find it necessary for the purposes of such opinions to cover, and
accordingly I express no opinion as to the application of the securities or blue
sky laws of, the various states to the sale of shares of Common Stock.

Such opinions are limited to the General Corporation Law of the State of
Wisconsin.  I assume no obligation to update or supplement this opinion to
reflect any facts or circumstances which may hereafter come to my attention with
respect to the opinions expressed above, including any changes in applicable law
which may hereafter occur.

Ladies and Gentlemen:

We refer to the proposed issuances and sales by you ("Company") of a presently

We have examined such documents and satisfied ourselves as to such matters of

authorized by your Board of Directors;

     2.   Such Note 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;

     4.   The Public Service Commission of Wisconsin shall have issued its
appropriate order or orders upon applications with respect to the Notes and
Common Stock; and

     5.   The Notes and Common Stock shall have been issued and sold in
accordance with the authorizations of the Board of Directors of the Company, and
the appropriate order or orders of the Public Service Commission of Wisconsin;
then

     (i)  the Notes 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 will be entitled to the benefits provided by the Note
Indenture.

     (iii) Upon the issuance of authorized and unissued shares of Common Stock
for consideration (but not less than the par value), such shares will, when
certificates representing such shares shall have been duly executed,
countersigned and registered, and duly delivered against the receipt by the
Company of such consideration be legally issued, fully paid and non-assessable,
except to the extent that such shares are assessable as provided in Section
180.0622 of the Wisconsin Business Corporation Law.

We are further of the opinion that no approval of any state or federal
regulatory authority, other than the Public Service Commission of Wisconsin and
the Commission under the Act and the 39 Act is required with respect to the
proposed offering, issuance and sale of the Notes and Common Stock.

We do not find it necessary for the purposes of such opinions, and accordingly
do not purport herein, to cover the application of state securities or "blue
sky" laws relating to sales and securities.

                                                                     Exhibit 5.3

Madison Gas and Electric Company
133 South Blair Street
P.O. Box 1231
Madison, Wisconsin 53701-1231

Ladies and Gentlemen:

     We have acted as counsel to you in connection with the proposed offering by
your corporation (the "Company"), of Medium-Term Notes (the "Notes") as
described in the Registration Statement on Form S-3 (the "Registration
Statement"), which is being filed by the Company with the Securities and
Exchange Commission pursuant to the Securities Act of 1933, as amended.  The
Registration Statement includes a Prospectus relating to such offering of Notes.

     In rendering the opinion expressed below, we have examined the Prospectus
and such other documents as we have deemed relevant and necessary, including,
without limitation, the form of Indenture attached as an Exhibit to the
Registration Statement.  Such opinion is conditioned, among other things, upon
the accuracy and completeness of the facts, information and representations
contained in the Prospectus as of the date hereof and the continuing accuracy
and completeness thereof as of the date of the issuance of the Notes.  We have
assumed that the transactions contemplated by the Prospectus and such other
documents will occur as provided therein and that there will be no material
change to the Prospectus or any of such other documents between the date hereof
and the date of the issuance of the Notes.

     Based upon and subject to the foregoing, we are of the opinion that the
discussion set forth in the Prospectus under the caption "UNITED STATES FEDERAL
INCOME TAX CONSEQUENCES" is a fair and accurate summary of the matters addressed
therein, based upon current law and the assumptions stated or referred to
therein.

     We assume no obligation to update or supplement this letter to reflect any
facts or circumstances which may hereafter come to our attention with respect to
the opinion expressed above, including any changes in applicable law which may
hereafter occur.

     We hereby consent to the filing of this opinion letter as an Exhibit to the
Registration Statement and to all references to our Firm included in or made a
part of the Registration Statement.

                                   Very truly yours,

                                   /s/ Sidley & Austin

Exhibit 1

BANK ONE, COLUMBUS, NATIONAL ASSOCIATION
                          ARTICLES OF ASSOCIATION

     For the purpose of organizing an association to carry on the business of
banking under the laws of the United States, the following Articles of
Association are entered into:

     FIRST. The title of this Association shall be BANK ONE, COLUMBUS, NATIONAL
ASSOCIATION.


     SECOND.  The main office of the Association shall be in Columbus, County of
Franklin, State of Ohio.  The general business of the Association shall be
conducted at its main office and its branches.


     THIRD.  The Board of Directors of this Association shall consist of not
less than five nor more than twenty-five Directors, the exact number of
Directors within such minimum and maximum limits to be fixed and determined from
time-to-time by resolution of the shareholders at any annual or special meeting
thereof, provided, however, that the Board of Directors, by resolution of a
majority thereof, shall be authorized to increase the number of its members by
not more than two between regular meetings of the shareholders.  Each Director,
during the full term of his directorship, shall own, as qualifying shares, the
minimum number of shares of either this Association or of its parent bank
holding company in accordance with the provisions of applicable law.  Unless
otherwise provided by the laws of the United States, any vacancy in the Board of
Directors for any reason, including an increase in the number thereof, may be
filled by action of the Board of Directors.


<PAGE>

     FOURTH.  The annual meeting of the shareholders for the election of
Directors and the transaction of whatever other business may be brought before
said meeting shall be held at the main office of this Association or such other
place as the Board of Directors may designate, on the day of each year specified
therefor in the By-Laws, but if no election is held on that day, it may be held
on any subsequent business day according to the provisions of law; and all
elections shall be held according to such lawful regulations as may be
prescribed by the Board of Directors.


     FIFTH.  The authorized amount of capital stock of this Association shall 
be 2,073,750 shares of common stock of the par value of Ten Dollars ($10) 
each; but said capital stock may be increased or decreased from time-to-time, 
in accordance with the provisions of the laws of the United States.

          No holder of shares of the capital stock of any class of the
Association shall have the preemptive or preferential right of subscription to
any share of any class of stock of this Association, whether now or hereafter
authorized or to any obligations convertible into stock of this Association,
issued or sold, nor any right of subscription to any thereof other than such, if
any, as the Board of Directors, in its discretion, may from time-to-time
determine and at such price as the Board of Directors may from time-to-time fix.

          This Association, at any time and from time-to-time, may authorize and
issue debt obligations, whether or not subordinated, without the approval of the
shareholders.


     SIXTH.  The Board of Directors shall appoint one of its members President
of the Association, who shall be Chairman of the Board, unless the Board
appoints another director to be the Chairman.  The Board of Directors shall have
the power to appoint one or more Vice Presidents and to appoint a Secretary and
such other officers and employees as may be required to transact the business of
this Association.


                                         -5-

<PAGE>

          The Board of Directors shall have the power to define the duties of
the officers and employees of this Association; to fix the salaries to be paid
to them; to dismiss them; to require bonds from them and to fix the penalty
thereof; to regulate the manner in which any increase of the capital of this
Association shall be made; to manage and administer the business and affairs of
this Association; to make all By-Laws that it may be lawful for them to make;
and generally to do and perform all acts that it may be legal for a Board of
Directors to do and perform.


     SEVENTH.  The Board of Directors shall have the power to change the
location of the main office to any other place within the limits of the City of
Columbus, Ohio, without the approval of the shareholders but subject to the
approval of the Comptroller of the Currency; and shall have the power to
establish or change the location of any branch or branches of this Association
to any other location, without the approval of the shareholders but subject to
the approval of the Comptroller of the Currency.


     EIGHTH.  The corporate existence of this Association shall continue until
terminated in accordance with the laws of the United States.


     NINTH.  The Board of Directors of this Association, or any three or more
shareholders owning, in the aggregate, not less than 10 percent of the stock of
this Association, may call a special meeting of shareholders at any time. 
Unless otherwise provided by the laws of the United States, a notice of the
time, place and purpose of every annual and special meeting of the shareholders
shall be given by first-class mail, postage prepaid, mailed at least ten days
prior to the date of such meeting to each shareholder of record at his address
as shown upon the books of this Association.


                                         -6-

<PAGE>

     TENTH.  Every person who is or was a Director, officer or employee of 
the Association or of any other corporation which he served as a Director, 
officer or employee at the request of the Association as part of his 
regularly assigned duties may be indemnified by the Association in accordance 
with the provisions of this paragraph against all liability (including, 
without limitation, judgments, fines, penalties and settlements) and all 
reasonable expenses (including, without limitation, attorneys' fees and 
investigative expenses) that may be incurred or paid by him in connection 
with any claim, action, suit or proceeding, whether civil, criminal or 
administrative (all referred to hereafter in this paragraphs as "Claims") or 
in connection with any appeal relating thereto in which he may become 
involved as a party or otherwise or with which he may be threatened by reason 
of his being or having been a Director, officer or employee of the 
Association or such other corporation, or by reason of any action taken or 
omitted by him in his capacity as such Director, officer or employee, whether 
or not he continues to be such at the time such liability or expenses are 
incurred, provided that nothing contained in this paragraph shall be 
construed to permit indemnification of any such person who is adjudged guilty 
of, or liable for, willful misconduct, gross neglect of duty or criminal 
acts, unless, at the time such indemnification is sought, such 
indemnification in such instance is permissible under applicable law and 
regulations, including published rulings of the Comptroller of the Currency 
or other appropriate supervisory or regulatory authority, and provided 
further that there shall be no indemnification of directors, officers, or 
employees against expenses, penalties, or other payments incurred in an 
administrative proceeding or action instituted by an appropriate regulatory 
agency which proceeding or action results in a final order assessing civil 
money penalties or requiring affirmative action by an individual or 
individuals in the form of payments to the Association.  Every person who may 
be indemnified under the provisions of this paragraph and who has been wholly 
successful on the merits with respect to any Claim shall be entitled to 
indemnification as of right.  Except as provided in the preceding sentence, 
any indemnification under this paragraph shall be at the sole discretion of 
the Board of Directors and shall be made only if the Board of Directors or 
the Executive Committee acting by a quorum consisting of 

                                         -7-
<PAGE>

Directors who are not parties to such Claim shall find or if independent legal
counsel (who may be the regular counsel of the Association) selected by the
Board of Directors or Executive Committee whether or not a disinterested quorum
exists shall render their opinion that in view of all of the circumstances then
surrounding the Claim, such indemnification is equitable and in the best
interests of the Association.  Among the circumstances to be taken into
consideration in arriving at such a finding or opinion is the existence or
non-existence of a contract of insurance or indemnity under which the
Association would be wholly or partially reimbursed for such indemnification,
but the existence or non-existence of such insurance is not the sole
circumstance to be considered nor shall it be wholly determinative of whether
such indemnification shall be made.  In addition to such finding or opinion, no
indemnification under this paragraph shall be made unless the Board of Directors
or the Executive Committee acting by a quorum consisting of Directors who are
not parties to such Claim shall find or if independent legal counsel (who may be
the regular counsel of the Association) selected by the Board of Directors or
Executive Committee whether or not a disinterested quorum exists shall render
their opinion that the Director, officer or employee acted in good faith in what
he reasonably believed to be the best interests of the Association or such other
corporation and further in the case of any criminal action or proceeding, that
the Director, officer or employee reasonably believed his conduct to be lawful. 
Determination of any Claim by judgment adverse to a Director, officer or
employee by settlement with or without Court approval or conviction upon a plea
of guilty or of NOLO CONTENDERE or its equivalent shall not create a presumption
that a Director, officer or employee failed to meet the standards of conduct set
forth in this paragraph.  Expenses incurred with respect to any Claim may be
advanced by the Association prior to the final disposition thereof upon receipt
of an undertaking satisfactory to the Association by or on behalf of the
recipient to repay such amount unless it is ultimately determined that he is
entitled to indemnification under this paragraph.  The rights of indemnification
provided in this paragraph shall be in addition to any rights to which any
Director, officer or employee may otherwise be entitled by contract or as a
matter of law. 


                                         -8-
<PAGE>

Every person who shall act as a Director, officer or employee of this
Association shall be conclusively presumed to be doing so in reliance upon the
right of indemnification provided for in this paragraph.


     ELEVENTH.  These Articles of Association may be amended at any regular or
special meeting of the shareholders by the affirmative vote of the holders of a
majority of the stock of this Association, unless the vote of the holders of a
greater amount of stock is required by law, and in that case by the vote of the
holders of such greater amount.

SECTION 1.01.  ANNUAL MEETING.  The regular annual meeting of the Shareholders
of the Bank for the election of Directors and for the transaction of such
business as may properly come before the meeting shall be held at its main
banking house, or other convenient place duly authorized by the Board of
Directors, on the third Monday of January of each year, or on the next
succeeding banking day, if the day fixed falls on a legal holiday.  If from any
cause, an election of directors is not made on the day fixed for the regular
meeting of shareholders or, in the event of a legal holiday, on the next
succeeding banking day, the Board of Directors shall order the election to be
held on some subsequent day, as soon thereafter as practicable, according to the
provisions of law; and notice thereof shall be given in the manner herein
provided for the annual meeting.  Notice of such annual meeting shall be given
by or under the direction of the Secretary or such other officer as may be
designated by the Chief Executive Officer by first-class mail, postage prepaid,
to all shareholders of record of the Bank at their respective addresses as shown
upon the books of the Bank mailed not less than ten days prior to the date fixed
for such meeting.


SECTION 1.02.  SPECIAL MEETINGS.  A special meeting of the shareholders of this
Bank may be called at any time by the Board of Directors or by any three or more
shareholders owning, in the aggregate, not less than ten percent of the stock of
this Bank.  The notice of any special meeting of the shareholders called by the
Board of Directors, stating the time, place and purpose of the meeting, shall be
given by or under the direction of the Secretary, or such other officer as is
designated by the Chief Executive Officer, by first-class mail, postage prepaid,
to all shareholders of 


                                         -10-
<PAGE>

record of the Bank at their respective addresses as shown upon the books of the
Bank, mailed not less than ten days prior to the date fixed for such meeting.

     Any special meeting of shareholders shall be conducted and its proceedings
recorded in the manner prescribed in these By-Laws for annual meetings of
shareholders.


SECTION 1.03.  SECRETARY OF SHAREHOLDERS' MEETING.  The Board of Directors may
designate a person to be the Secretary of the meetings of shareholders.  In the
absence of a presiding officer, as designated in these By-Laws, the Board of
Directors may designate a person to act as the presiding officer.  In the event
the Board of Directors fails to designate a person to preside at a meeting of
shareholders and a Secretary of such meeting, the shareholders present or
represented shall elect a person to preside and a person to serve as Secretary
of the meeting.


     The Secretary of the meetings of shareholders shall cause the returns made
by the judges and election and other proceedings to be recorded in the minute
book of the Bank.  The presiding officer shall notify the directors-elect of
their election and to meet forthwith for the organization of the new board.


     The minutes of the meeting shall be signed by the presiding officer and the
Secretary designated for the meeting.


SECTION 1.04.  JUDGES OF ELECTION.  The Board of Directors may appoint as many
as three shareholders to be judges of the election, who shall hold and conduct
the same, and who shall, after the election has been held, notify, in writing
over their signatures, the secretary of the shareholders' meeting of the result
thereof and the names of the Directors elected; provided, however, that upon
failure for any reason of any judge or judges of election, so appointed by the
directors, to serve, the presiding officer of the meeting shall appoint other
shareholders or their proxies to fill the vacancies.  The judges of election at
the request of the chairman of the 


                                         -11-
<PAGE>

meeting, shall act as tellers of any other vote by ballot taken at such meeting,
and shall notify, in writing over their signatures, the secretary of the Board
of Directors of the result thereof.


SECTION 1.05.  PROXIES.  In all elections of Directors, each shareholder of
record, who is qualified to vote under the provisions of Federal Law, shall have
the right to vote the number of shares of record in his name for as many persons
as there are Directors to be elected, or to cumulate such shares as provided by

SECTION 2.01.  MANAGEMENT OF THE BANK.  The business of the Bank shall be

beneficial owner of a substantial number of shares of BANC ONE CORPORATION and
shall be employed either in the position of Chief Executive Officer or active
leadership within his or her business, professional or community interest which
shall be located within the geographic area in which the Bank operates, or as an
executive officer of the Bank.  A director shall not be eligible for nomination
and re-election as a director of the Bank if such person's executive or
leadership position within his or her business, professional or community
interests which qualifies such person as a director of Bank terminates.  The age
of 70 is the mandatory retirement age as a director of the Bank.  When a
person's eligibility as director of the Bank terminates, whether because of
change in share ownership, position, residency or age, within 30 days after such
termination, such person shall submit his resignation as a director to be
effective at the pleasure of the Board provided, however, that in no event shall
such person be nominated or elected as a director.  Provided, however, following
a person's retirement or resignation as a director because of the age
limitations herein set forth with respect to election or re-election as a
director, such person may, in special or unusual circumstances, and at the
discretion of the Board, be elected by the directors as a Director Emeritus of
the Bank for a limited period of time.  A Director Emeritus shall have the right
to participate in board meetings but shall be without the power to vote and
shall be subject to re-election by the Board at its organizational meeting
following the Bank's annual meeting of shareholders.


SECTION 2.02.  QUALIFICATIONS.  Each director shall have the qualification
prescribed by law.  No person elected a director may exercise any of the powers
of his office until he has taken the oath of such office.

SECTION 2.03.  TERM OF OFFICE/VACANCIES.  A director shall hold office until the
annual meeting for the year in which his term expires and until his successor
shall be elected and shall qualify, subject, however, to his prior death,
resignation, or removal from office. Whenever any vacancy shall occur among the
directors, the remaining directors shall constitute the directors of the Bank
until such vacancy is filled by the remaining directors, and any director so
appointed shall hold office for the unexpired term of his or her successor. 
Notwithstanding the foregoing, each director shall hold office and serve at the
pleasure of the Board.


SECTION 2.04.  ORGANIZATION MEETING.  The directors elected by the share-
holders shall meet for organization of the new board at the time fixed by the
presiding officer of the annual meeting.  If at the time fixed for such meeting
there is no quorum present, the Directors in attendance may adjourn from time to
time until a quorum is obtained.  A majority of the number of Directors elected
by the shareholders shall constitute a quorum for the transaction of business.


SECTION 2.05.  REGULAR MEETINGS.  The regular meetings of the Board of Directors
shall be held on the third Monday of each calendar month excluding March and
July, which meeting will be held at 4:00 p.m.  When any regular meeting of the
Board falls on a holiday, the meeting shall be held on such other day as the
Board may previously designate or should the Board fail to so designate, on such
day as the Chairman of the Board of President may fix.  Whenever a quorum is not
present, the directors in attendance shall adjourn the meeting to a time not
later than the date fixed by the Bylaws for the next succeeding regular meeting
of the Board.


SECTION 2.06.  SPECIAL MEETINGS.  Special meetings of the Board of Directors
shall be held at the call of the Chairman of the Board or President, or at the
request of two or more Directors.  Any special meeting may be held at such place
in Franklin County, Ohio, and at such time as may be fixed in the call.  Written
or oral notice shall be given to each Director not later than the day next
preceding the day on which special meeting is to be held, which notice may be
waived in writing. 


                                         -14-
<PAGE>

The presence of a Director at any meeting of the Board shall be deemed a waiver
of notice thereof by him.  Whenever a quorum is not present the Directors in
attendance shall adjourn the special meeting from day to day until a quorum is
obtained.


SECTION 2.07.  QUORUM.  A majority of the Directors shall constitute a quorum at
any meeting, except when otherwise provided by law; but a lesser number may
adjourn any meeting, from time-to-time, and the meeting may be held, as
adjourned, without further notice.  When, however, less than a quorum as herein
defined, but at least one-third and not less than two of the authorized number
of Directors are present at a meeting of the Directors, business of the Bank may
be transacted and matters before the Board approved or disapproved by the
unanimous vote of the Directors present.


SECTION 2.08.  COMPENSATION.  Each member of the Board of Directors shall
receive such fees for, and transportation expenses incident to, attendance at
Board and Board Committee Meetings and such fees for service as a Director
irrespective of meeting attendance as from time to time are fixed by resolution
of the Board; provided, however, that payment hereunder shall not be made to a
Director for meetings attended and/or Board service which are not for the Bank's
sole benefit and which are concurrent and duplicative with meetings attended or
board service for an affiliate of the Bank for which the Director receives
payment; and provided further, that payment hereunder shall not be made in the
case of any Director in the regular employment of the Bank or of one of its
affiliates.


SECTION 2.09.  EXECUTIVE COMMITTEE.  There shall be a standing committee of the
Board of Directors known as the Executive Committee which shall possess and
exercise, when the Board is not in session, all powers of the Board that may
lawfully be delegated.  The Executive Committee shall also exercise the powers
of the Board of Directors in accordance with the Provisions of the "Employees
Retirement Plan" and the "Agreement and Declaration of Trust" as the same now 


                                         -15-

exist or may be amended hereafter.  The Executive Committee shall consist of 
not fewer than four board members, including the Chairman of the Board and 
President of the Bank, one of whom, as hereinafter required by these By-laws, 
shall be the Chief Executive Officer.  The other members of the Committee 
shall be appointed by the Chairman of the Board or by the President, with the 
approval of the Board and shall continue as members of the Executive 
Committee until their successors are appointed, provided, however, that any 
member of the Executive Committee may be removed by the Board upon a majority 
vote thereof at any regular or special meeting of the Board.  The Chairman or 
President shall fill any vacancy in the Committee by the appointment of 
another Director, subject to the approval of the Board of Directors.  The 
regular meetings of the Executive Committee shall be held on a regular basis 
as scheduled by the Board of Directors.  Special meetings of the Executive 
Committee shall be held at the call of the Chairman or President or any two 
members thereof at such time or times as may be designated. In the event of 
the absence of any member or members of the Committee, the presiding member 
may appoint a member or members of the Board to fill the place or places of 
such absent member or members to serve during such absence.  Not fewer than 
three members of the Committee must be present at any meeting of the 
Executive Committee to constitute a quorum, provided, however that with 
regard to any matters on which the Executive Committee shall vote, a majority 
of the Committee members present at the meeting at which a vote is to be 
taken shall not be officers of the Bank and, provided further, that if, at 
any meeting at which the Chairman of the Board and President are both 
present, Committee members who are not officers are not in the majority, then 
the Chairman of the Board or President, which ever of such officers is not 
also the Chief Executive Officer, shall not be eligible to vote at such 
meeting and shall not be recognized for purposes of determining if a quorum 
is present at such meeting. When neither the Chairman of the Board nor 
President are present, the Committee shall appoint a presiding officer.  The 
Executive Committee shal keep a record of its proceedings and report its 
proceedings and the action taken by it to the Board of Directors.
