incorporated in 1941 as the successor to the New York corporation of the same
name organized in 1898, is a worldwide producer of printing and writing papers,

                                  (UNAUDITED)
 
    The following table shows the Company's ratio of earnings to fixed charges
on a historical basis for each of the five years in the period ended December
31, 1995 and for the six-month periods ended June 30, 1995 and June 30, 1996.

Ratio of Earnings to Fixed Charges......  2.47  1.44  2.26  2.43  3.66  3.87  2.21
</TABLE>
 
    For purposes of computing the ratio of earnings to fixed charges, earnings
include pre-tax earnings before minority interest expense, extraordinary items
and the cumulative effect of accounting changes, interest expense, preferred
dividends of a subsidiary and the estimated interest factor in rent expense
(which, in the opinion of the Company, approximates one-third of rent expense),
and adjustments for minority interest expense, undistributed equity earnings and
the amortization of capitalized interest. Fixed charges include interest
incurred (including amounts capitalized), the estimated interest factor in rent
expense and preferred dividends of a subsidiary. Dividends on the Company's $4
Preferred Stock ($4 per share per annum) are insignificant and, as a result, the
ratio of earnings to combined fixed charges and preferred stock dividends and
the ratio of earnings to fixed charges are the same.

    THE FOLLOWING DESCRIPTION OF THE PARTICULAR TERMS OF THE NOTES OFFERED
HEREBY (REFERRED TO IN THE PROSPECTUS AS "SENIOR DEBT SECURITIES") SUPPLEMENTS,
AND TO THE EXTENT INCONSISTENT THEREWITH REPLACES, THE DESCRIPTION OF THE
GENERAL TERMS AND PROVISIONS OF SENIOR DEBT SECURITIES SET FORTH UNDER THE
HEADING "DESCRIPTION OF DEBT SECURITIES" IN THE ACCOMPANYING PROSPECTUS, TO
WHICH DESCRIPTION REFERENCE IS HEREBY MADE. CAPITALIZED TERMS NOT DEFINED HEREIN
HAVE THE MEANINGS ASSIGNED TO SUCH TERMS IN THE PROSPECTUS. SECTION REFERENCES
HEREIN ARE TO SECTIONS OF THE INDENTURE, DATED AS OF APRIL 1, 1994, BETWEEN THE
COMPANY AND THE CHASE MANHATTAN BANK, N.A. (PREDECESSOR TO THE CHASE MANHATTAN
BANK), AS TRUSTEE, (THE "INDENTURE") OR, WHERE SO INDICATED, TO THE OFFICERS'
CERTIFICATE ESTABLISHING CERTAIN TERMS OF THE NOTES PURSUANT TO SECTION 3.1 OF
THE INDENTURE (THE "OFFICERS' CERTIFICATE"). THE INDENTURE CONTAINS CERTAIN
COVENANTS WHICH ARE DESCRIBED UNDER THE HEADING "DESCRIPTION OF DEBT SECURITIES
- -- CERTAIN COVENANTS OF THE COMPANY" AS SET FORTH IN THE ACCOMPANYING
PROSPECTUS. THE FOLLOWING DESCRIPTION OF NOTES WILL APPLY TO SUCH NOTES UNLESS
OTHERWISE SPECIFIED IN A PRICING SUPPLEMENT.
 
    The Notes constitute a single series for purposes of the Indenture and are
limited to an aggregate offering price of U.S. $975,000,000 or the equivalent,
in the case of Foreign Currency Notes, at the Market Exchange Rate on the
applicable trade date, in one or more foreign currencies or currency units, and
in any case subject to reduction as a result of the sale of other Securities of
the Company, pursuant to the Registration Statement of which this Prospectus is
a part, and by action of the Company's board of directors.
 
    Unless previously redeemed, each Note will mature on a business day 18
months to 40 years from its date of issue, as selected by the initial purchaser
and agreed to by the Company.
 
    The Notes, other than Foreign Currency Notes, will be issuable only in fully
registered form in denominations of U.S. $50,000 and integral multiples of U.S.
$1,000 in excess thereof. For a description of the denominations of Foreign
Currency Notes, see "Special Provisions Relating to Foreign Currency Notes."
 
    Each Note will be issued initially as either a Book-Entry Note or a
Certificated Note. Except as set forth below under "Book-Entry Notes,"
Book-Entry Notes will not be issuable in definitive form.
 
    Interest rates offered by the Company with respect to the Notes may differ
depending upon among other things, the aggregate principal amount purchased in
any single transaction.
 
    The Notes may be issued as Original Issue Discount Notes. An Original Issue
Discount Note is a Note, including any Zero-Coupon Note, which is issued at a
price lower than the amount payable at the Stated Maturity thereof. Original
Issue Discount Notes, as well as certain other Notes offered hereunder, may, for
United States federal income tax purposes, be considered discount securities
(the "Discount Securities"). The principal United States federal income tax
consequences of the ownership of a Discount Security are described under "United
States Taxation -- Original Issue Discount."
 
    The Notes may be issued as Indexed Notes. An Indexed Note is a Note that may
receive a principal amount at Maturity that is either greater than or less than
the face amount of such Note, depending upon the fluctuation of the relative
value, rate or price of the specified index. Specific information pertaining to
the method for determining the principal amount payable at Maturity, a
historical comparison of the relative value, rate or price of the specified
index and the face amount of the Indexed Note and certain additional tax
considerations may be described in the applicable Pricing Supplement.
 
    Unless otherwise indicated in the applicable Pricing Supplement, the Notes
will be denominated in U.S. dollars and payments of principal of, premium, if
any, and interest on the Notes will be made in U.S. dollars. If any of the Notes
are to be denominated in a currency other than U.S. dollars, or if the principal
of, premium, if any, and interest on any of the Notes is to be payable at the
option of the Holder or the Company in a currency other than that in which such
Note is denominated, the applicable Pricing Supplement will provide additional
information pertaining to the terms of such Notes and other matters of interest
to the Holders thereof.
 
                                      S-3
<PAGE>
    Payments of principal of, premium, if any, and interest payable at Maturity
or upon acceleration or redemption, if any, on a Certificated Note will be made
in immediately available funds at the offices of The Chase Manhattan Bank in the
Borough of Manhattan, The City of New York, as paying agent (the "Paying
Agent"), provided that the Note is presented to the Paying Agent in time for the
Paying Agent to make such payments in such funds in accordance with its normal
procedures.
 
    The total amount of any principal, premium, if any, and/or interest due on
any Global Note representing one or more Book-Entry Notes on any Interest
Payment Date or at the Stated Maturity will be made available to the Trustee on
such date. As soon as possible thereafter, the Trustee will make such payments
to the Depository, in accordance with existing arrangements between the Trustee
and the Depository. The Depository will allocate such payments to each
Book-Entry Note represented by such Global Note and make payments to the owners
or holders thereof in accordance with its existing operating procedures. Neither
the Company nor the Trustee shall have any responsibility or liability for such
payments by the Depository. So long as the Depository or its nominee is the
registered owner of any Global Note, the Depository or its nominee, as the case
may be, will be considered the sole owner or holder of the Book-Entry Note or
Notes represented by such Global Note for all purposes under the Indenture. The
Company understands, however, that under existing industry practice, the
Depository will authorize the persons on whose behalf it holds a Global Note to
exercise certain rights of holders of Notes. See "Description of Notes --
Book-Entry Notes."
 
    Certificated Notes may be presented for registration of transfer or exchange
at the principal corporate trust office of The Chase Manhattan Bank (the
"Trustee"), in the Borough of Manhattan, The City of New York. With respect to
transfers of Book-Entry Notes and exchanges of Global Notes representing Book-
Entry Notes, see "Description of Notes -- Book-Entry Notes."
 
    The applicable Pricing Supplement will indicate either that the Notes cannot
be redeemed at the option of the Company prior to their Stated Maturity or that
the Notes may be redeemable at the option of the Company on or after a specified
date prior to their Stated Maturity at specified prices (which may include a
premium), together with accrued interest to the date of redemption. Unless
otherwise indicated in the applicable Pricing Supplement, the Notes will be
subject to redemption at the option of Holders of the Notes upon the occurrence
of certain events. For a description of terms of redemption at the option of
Holders, see "Description of Debt Securities -- Redemption at the Option of
Holders Upon Change of Control" in the Prospectus.
 
    The Notes will not be subject to any sinking fund.
 
    The Notes will not be convertible into or exchangeable for the Company's
common stock or other securities of the Company.
 
    The Indenture provisions relating to legal and covenant defeasance which are
described in the accompanying Prospectus under "Description of Debt Securities
- -- Defeasance" will apply to the Notes.
 
REDEMPTION AT THE OPTION OF THE COMPANY
 
    Unless otherwise specified in the applicable Pricing 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 Date only if agreed to by the
Company and the purchasers thereof at the time of sale and an initial redemption
date is specified in the applicable Pricing Supplement. If so specified, the
Notes will be subject to redemption at the option of the Company on any date on
and after the applicable initial redemption date in whole or from time to time
in part in increments of $50,000 or such other minimum denomination specified in
such Pricing Supplement (provided that any remaining principal amount thereof
shall be at least $1,000 or such minimum denomination), at the applicable
redemption price (as hereinafter defined), together with unpaid interest accrued
to the date of redemption, on notice given not more than 60 nor less than 30
calendar days prior to the date of redemption and in accordance with the
provisions of the Indenture. "Redemption Price," with respect to a Note, means
an amount equal to the initial redemption percentage specified in the applicable
Pricing Supplement (as adjusted by the annual redemption percentage reduction,
if applicable) multiplied by the unpaid principal amount to be redeemed. The
initial redemption percentage, if any,
 
                                      S-4
<PAGE>
applicable to a Note shall decline at each anniversary of the initial redemption
date by an amount equal to the applicable annual redemption percentage
reduction, if any, until the Redemption Price is equal to 100% of the unpaid
principal amount to be redeemed.
 
REPAYMENT AT THE OPTION OF THE HOLDER
 
    The Notes will be repayable by the Company at the option of the Holders
thereof prior to the Stated Maturity Date only if agreed so by the Company and
the purchasers thereof at the time of sale and one or more Optional Repayment
Dates are specified in the applicable Pricing Supplement. If so specified, the
Notes will be subject to repayment at the option of the Holders thereof on any
Optional Repayment Date in whole or from time to time in part in increments of
$50,000 or such other minimum denomination specified in the applicable Pricing
Supplement (provided that any remaining principal amount thereof shall be at
least $1,000 or such other minimum denomination), at a repayment price equal to
100% of the unpaid principal amount to be repaid, together with unpaid interest
accrued to the date of repayment. For any Note to be repaid, such Note must be
received, together with the form thereon entitled "Option to Elect Repayment"
duly completed, by the Trustee at its Corporate Trust Office (or such other
address of which the Company shall from time to time notify the Holders) not
more than 60 nor less than 30 calendar days prior to the date of repayment.
Exercise of such repayment option by the Holder will be irrevocable.
 
    Only the Depository may exercise the repayment option in respect of Global
Securities representing Book-Entry Notes. Accordingly, Beneficial Owners (as
hereinafter defined) of Global Securities that desire to have all or any portion
of the Book-Entry Notes represented by such Global Securities repaid must direct
the Participant (as hereinafter defined) through which they own their interest
to direct the Depository to exercise the repayment option on their behalf by
delivering the related Global Security and duly completed election form to the
Trustee as aforesaid. In order to ensure that such Global Security and election
form are received by the Trustee on a particular day, the applicable Beneficial
Owner must so direct the Participant through which it owns its interest 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 should consult the Participants
through which they own their interest for the respective deadlines for such
Participants. All instructions given to Participants from Beneficial Owners of
Global Securities relating to the option to elect repayment shall be
irrevocable. In addition, at the time such instructions are given, each such
Beneficial Owner shall cause the Participant through which it owns its interest
to transfer such Beneficial Owner's interest in the Global Security or
Securities representing the related Book-Entry Notes, on the Depository's
records, to the Trustee. See "Description of Notes -- Book-Entry Notes."
 
    If applicable, the Company will comply with the requirements of Rule 14e-1
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
any other securities laws or regulations in connection with any such repayment.
 
    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, at the
discretion of the Company, be held, resold or surrendered to the Trustee for
cancellation.
 
INTEREST
 
    Each Note, except a Zero-Coupon Note, will bear interest from and including
the date of issue or from and including the most recent Interest Payment Date to
which interest on such Note has been paid or duly provided for to, but
excluding, the relevant Interest Payment Date at the fixed rate per annum, or at
the rate per annum determined pursuant to the interest rate formula stated
therein and in the applicable Pricing Supplement, until the principal thereof is
paid or made available for payment. Interest payments, if any, will be in the
amount of interest accrued from and including the next preceding Interest
Payment Date in respect of which interest has been paid or duly provided for (or
from and including the date of issue, if no interest has been paid with respect
to such Note) to, but excluding, the applicable Interest Payment Date.
 
    Interest, if any, will be payable on each Interest Payment Date and at
Maturity; provided, however, if a Note is issued between a Regular Record Date
and an Interest Payment Date, the interest so payable for the
 
                                      S-5
<PAGE>
period from the date of issue to such Interest Payment Date shall be paid on the
next succeeding Interest Payment Date to the Registered Holder thereof on the
related Regular Record Date. Interest will be payable to the person (which in
the case of a Global Note representing Book-Entry Notes shall be the Depositary)
in whose name an interest-bearing Note is registered at the close of business on
the Regular Record Date next preceding each Interest Payment Date; PROVIDED,
HOWEVER, that interest payable at Maturity or, if applicable, upon redemption,
will be payable to the person to whom principal shall be payable. Unless
otherwise indicated in the applicable Pricing Supplement, the Regular Record
Date with respect to Floating Rate Notes shall be the date 15 calendar days
prior to each Interest Payment Date, whether or not such date shall be a
Business Day, and the Regular Record Dates with respect to Fixed Rate Notes
shall be the January 15 and July 15 next preceding the February 1 and August 1
Interest Payment Dates.
 
    Each Note, except a Zero-Coupon Note, will bear interest at either (a) a
fixed rate or rates (a "Fixed Rate Note") or (b) a variable rate determined by
reference to an interest rate formula (a "Floating Rate Note"), which may be
adjusted by adding or subtracting the Spread or multiplying by the Spread
Multiplier, unless otherwise specified therein and in the applicable Pricing
Supplement. Holders of Zero-Coupon Notes will receive no periodic payments of
interest on such Notes.
 
    Interest rates 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.
 
FIXED RATE NOTES
 
    The applicable Pricing Supplement relating to a Fixed Rate Note will
designate a fixed rate of interest per annum payable on such Note. Unless
otherwise indicated in the applicable Pricing Supplement, the Interest Payment
Dates for Fixed Rate Notes will be February 1 and August 1 of each year and at
Maturity, and, if applicable, upon redemption. Unless otherwise indicated in the
applicable Pricing Supplement, interest payments for Fixed Rate Notes shall be
the amount of interest accrued to but excluding the relevant Interest Payment
Date. Interest on such Note will be computed on the basis of a 360-day year of
twelve 30-day months. If an Interest Payment Date or the Maturity of a Fixed
Rate Note falls on a day that is not a Business Day, the payment of principal,
premium, if any, and interest will be made on the next succeeding Business Day,
and no interest on such payment shall accrue from and after such Interest
Payment Date or Maturity. Unless otherwise indicated in the applicable Pricing
Supplement the Regular Record Date with respect to Fixed Rate Notes shall be the
date 15 calendar days prior to each Interest Payment Date, whether or not such
date shall be a Business Day.
 
FLOATING RATE NOTES
 
    The applicable Pricing Supplement relating to a Floating Rate Note will
designate an interest rate basis for such Floating Rate Note. Such basis may be:
(a) the Commercial Paper Rate, in which case such Note will be a Commercial
Paper Rate Note, (b) the Prime Rate, in which case such Note will be a Prime
Rate Note, (c) the CD Rate, in which case such Note will be a CD Rate Note, (d)
the Federal Funds Rate, in which case such Note will be a Federal Funds Rate
Note, (e) LIBOR, in which case such Note will be a LIBOR Note, (f) the Treasury
Rate, in which case such Note will be a Treasury Rate Note, or (g) such other
interest rate formula as may be agreed to between the Company and the purchaser
and set forth in such Pricing Supplement. In addition, a Floating Rate Note may
bear interest at the lowest or highest or average of two or more interest rate
formulae. The applicable Pricing Supplement for a Floating Rate Note also will
specify the Spread or Spread Multiplier, if any, and the maximum or minimum
interest rate limitation, if any, applicable to each Note. In addition, such
Pricing Supplement will define or particularize for each Floating Rate Note the
following terms, if applicable: Calculation Agent; Calculation Dates; Initial
Interest Rate (which rate shall be determined on the same basis as that
subsequently applicable to such Note); Interest Payment Dates; Regular Record
Dates; Index Maturity; Interest Determination Dates; Interest Reset Dates;
Redemption Prices; and Redemption Dates with respect to such Note. See
"Glossary" for definitions of certain terms used in this Prospectus Supplement.
 
                                      S-6
<PAGE>
    The rate of interest on a Floating Rate Note in effect on any date will be
(a) if such day is an Interest Reset Date with respect to such Floating Rate
Note, the interest rate on such Floating Rate Note determined as of the Interest
Determination Date pertaining to such Interest Reset Date, or (b) if such day is
not an Interest Reset Date with respect to such Floating Rate Note, the interest
rate on such Floating Rate Note determined as of the Interest Determination Date
pertaining to the immediately preceding Interest Reset Date with respect to such
Floating Rate Note; PROVIDED, HOWEVER, that the interest rate in effect from the
Issue Date of a Floating Rate Note (or that of a predecessor Note) to but
excluding the first Interest Reset Date with respect to such Floating Rate Note
will be the Initial Interest Rate (as set forth in the applicable Pricing
Supplement). Subject to applicable provisions of law and except as described
herein, the rate of interest on a Floating Rate Note on any Interest Reset Date
with respect thereto will be the rate of interest determined with respect to the
Interest Determination Date pertaining to such Interest Reset Date as determined
in accordance with the applicable provisions described below.
 
    The rate of interest on each Floating Rate Note will be reset daily, weekly,
monthly, quarterly, semiannually or annually (each an "Interest Reset Date"), as
specified in the applicable Pricing Supplement. Unless otherwise specified in
the applicable Pricing Supplement, the Interest Reset Date will be, in the case
of Floating Rate Notes which reset daily, each Business Day; 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,
except as provided in the following paragraph, the Tuesday of each week; 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 March, June, September and December; in the case of Floating Rate
Notes which reset semiannually, the third Wednesday of two months of each year,
as indicated in the applicable Pricing Supplement; and in the case of Floating
Rate Notes which reset annually, the third Wednesday of one month of each year,
as indicated in the applicable Pricing Supplement. If any Interest Reset Date
for any Floating Rate Note would otherwise be a day that is not a Business Day
with respect to such Note, such Interest Reset Date shall be the next succeeding
Business Day with respect to such Note, except that if such Note is a LIBOR Note
and the next succeeding Business Day falls in the next succeeding calendar
month, such Interest Reset Date shall be the immediately preceding Business Day.
 
    The Interest Determination Date pertaining to an Interest Reset Date for a
Commercial Paper Rate Note (the "Commercial Paper Interest Determination Date"),
a Prime Rate Note (the "Prime Rate Interest Determination Date"), a CD Rate Note
(the "CD Rate Interest Determination Date") or a Federal Funds Rate Note (the
"Federal Funds Interest Determination Date") will be the second Business Day
preceding the Interest Reset Date with respect to such Note. 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
preceding such Interest Reset Date. The Interest Determination Date pertaining
to an Interest Reset Date for a Treasury Rate Note (the "Treasury Interest
Determination Date") will be the day on which Treasury bills are auctioned for
the week in which such Interest Reset Date falls, or if no auction is held for
such week, the Monday of such week (or if Monday is a legal holiday, the next
succeeding Business Day) and the Interest Reset Date will be the Business Day
immediately following such Treasury Interest Determination Date. 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 for
such week is held on Monday or the preceding Friday, such Monday or preceding
Friday shall be the Treasury Interest Determination Date for such week, and the
Interest Reset Date for such week shall be the Tuesday of such week (or, if such
Tuesday is not a Business Day, the next succeeding Business Day). If the auction
for such week is held on any day of such week other than Monday, then such day
shall be the Treasury Interest Determination Date and the Interest Reset Date
for such week shall be the next succeeding Business Day.
 
    A Floating Rate Note may have either or both of the following: (a) a maximum
numerical interest rate limitation, or ceiling, on the rate of interest which
may accrue during any interest period; and (b) a minimum numerical interest rate
limitation, or floor, on the rate of interest which may accrue during any
interest period. In addition to any maximum interest rate which may be
applicable to any Floating Rate Note, the interest rate on such Floating Rate
Note will in no event be higher than the maximum rate permitted by New
 
                                      S-7
<PAGE>
York law, as the same may be modified by United States law of general
application. Under present New York law the maximum rate of interest, with
certain exceptions, is 25% per annum on a simple interest basis. The limit may
not apply to Notes in which $2,500,000 or more has been invested.
 
    Unless otherwise indicated in the applicable Pricing Supplement and except
as provided below, the Interest Payment Date will be, in the case of Floating
Rate Notes which 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 indicated in the applicable Pricing Supplement); in the case of Floating
Rate Notes which reset quarterly, the third Wednesday of March, June, September
and December of each year; in the case of Floating Rate Notes which reset
semiannually, the third Wednesday of the two months of each year specified in
the applicable Pricing Supplement; and in the case of Floating Rate Notes which
reset annually, the third Wednesday of the month specified in the applicable
Pricing Supplement. If, pursuant to the preceding sentence, an Interest Payment
Date with respect to any Floating Rate Note (other than an Interest Payment Date
at Maturity) would otherwise be a day that is not a Business Day with respect to
such Note, such Interest Payment Date shall be the next succeeding Business Day
with respect to such Note, except that if such Note is a LIBOR Note and the next
succeeding Business Day falls in the next succeeding calendar month, such
Interest Payment Date shall be the immediately preceeding Business Day. If the
Maturity of a Floating Rate Note falls on a day that is not a Business Day, the
payment of principal, premium, if any, and interest will be made on the next
succeeding Business Day, and no interest on such payment shall accrue from and
after such Maturity. Unless otherwise indicated in the applicable Pricing
Supplement the Regular Record Date with respect to Floating Rate Notes shall be
the date 15 calendar days prior to each Interest Payment Date, whether or not
such date shall be a Business Day.
 
    Unless otherwise specified in the applicable Pricing Supplement, the
interest accrued from and including the date of issue, or from and including the
last date to which interest has been paid or duly provided for, is calculated by
multiplying the face amount of such Floating Rate Note by an accrued interest
factor. Such accrued interest factor is computed by adding the interest factor
calculated for each day in such period from and including the date of issue, 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. Unless otherwise specified in the Note and the applicable Pricing
Supplement, the interest factor (expressed as a decimal rounded upwards, if
necessary, as described below) for each such day is computed by dividing the
interest rate (expressed as a decimal rounded upwards, if necessary, as
described below) applicable to such date by 360, (or, in the case of the
Treasury Rate Notes, by the actual number of days in the year). The interest
factor for Notes for which two or more interest rate formulae are applicable
will be calculated in each period in the same manner as if only the lowest,
highest or average of, as the case may be, such interest rate formulae applied.
 
    Unless otherwise specified in the applicable Pricing Supplement, all
percentages resulting from any calculation on Floating Rate Notes will be
rounded, upwards if necessary, to the next higher one-hundred thousandth of a
percentage point, with five one-millionths of a percentage point rounded upwards
(e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655) and
9.876544% (or .09876544) being rounded to 9.87654% (or .0987654)), and all
dollar amounts used in or resulting from such calculation on Floating Rate Notes
will be rounded to the nearest cent or, in the case of Foreign Currency Notes,
the nearest unit (with one-half cent or five one-thousandths of a unit being
rounded upwards).
 
    Upon the request of the Holder of any Floating Rate Note, the Calculation
Agent will provide the interest rate then in effect, and, if different, the
interest rate which will become effective as a result of a determination made on
the most recent Interest Determination Date with respect to such Floating Rate
Note.
 
    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 or Spread
Multiplier, if any), and will be payable on the dates, specified on the face of
such Note and in the applicable Pricing Supplement.
 
                                      S-8

    Unless otherwise indicated in the applicable Pricing 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
Pricing Supplement as published by the Board of Governors of the Federal Reserve
System in "Statistical Release H.15 (519), Selected Interest Rates" ("H.15
(519)"), or any successor publication of the Board of Governors of the Federal
Reserve System, under the heading "Commercial Paper." In the event that such
rate is not published prior to 3:00 p.m., New York City time, on the Calculation
Date pertaining to such Commercial Paper Interest Determination Date, then the
Commercial Paper Rate shall 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 Pricing 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" ("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 yet published in either
H.15(519) or Composite Quotations, the Commercial Paper Rate for that Commercial
Paper Interest Determination Date shall be the Money Market Yield of the
arithmetic mean, as calculated by the Calculation Agent on such Calculation
Date, of the offered rates, as of 11:00 a.m., New York City time, on that
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 Pricing
Supplement placed for an industrial issuer whose bond rating is "AA," or the
equivalent, from a nationally recognized rating agency; PROVIDED, HOWEVER, that
if fewer than three dealers selected as aforesaid by the Calculation Agent are
quoting as mentioned in this sentence, the Commercial Paper Rate will be the
Commercial Paper Rate in effect on such Commercial Paper Interest Determination
Date.
 
    "Money Market Yield" shall be a yield (expressed as a percentage rounded
upwards, if necessary, to the next higher one hundred thousandth of a percentage
point) calculated in accordance with the following formula:
 
<TABLE>
<C>                                             <C>              <S>        <C>
                                                    D X 360
                          Money Market Yield =  --------------   = 100
                                                 360 - (D X M)
</TABLE>
 
where "D" refers to the per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal; and "M" refers to the actual number
of days in the interest period for which interest is being calculated.
 
    PRIME RATE NOTES
 
    Each Prime Rate Note will bear interest at the interest rate (calculated
with reference to the Prime Rate and the Spread or Spread Multiplier, if any)
specified on the face of such Prime Rate Note and in the applicable Pricing
Supplement.
 
    Unless otherwise specified in the applicable Pricing Supplement, "Prime
Rate" means, with respect to any Interest Determination Date relating to a
Floating Rate Note for which the interest rate is determined with reference to
the Prime Rate (a "Prime Rate Interest Determination Date"), the rate on such
date as such rate is published in H.15(519) under the heading "Bank Prime Loan."
If such rate is not published prior to 3:00 p.m., New York City time, on the
related Calculation Date, then the Prime Rate shall be the arithmetic mean of
the rates of interest publicly announced by each bank that appears on the
Reuters Screen USPRIME1 Page (as hereinafter defined) as such bank's prime rate
or base lending rate as in effect for such Prime Rate Interest Determination
Date. If fewer than four such rates appear on the Reuters Screen USPRIME1 Page
for such Prime Rate Interest Determination Date, then the Prime Rate shall be
the arithmetic mean of the prime rates quoted on the basis of the actual number
of days in the year divided by a 360-day year as of the close of business on
such Prime Rate Interest Determination Date by four major money center banks in
The City of New York selected by the Calculation Agent. If fewer than four such
quotations are so provided, then the Prime Rate shall be the arithmetic mean of
four prime rates quoted on the basis of the actual number of days in the year
divided by a 360-day year as of the close of business on such
 
                                      S-9
<PAGE>
Prime Rate Interest Determination Date as furnished in The City of New York by
the major money center banks, if any, that have provided such quotations and by
a reasonable number of substitute banks or trust companies as necessary in order
to obtain four such prime rate quotations, provided such substitute banks or
trust companies are organized and doing business under the laws of the United
States, or any State thereof, each having total equity capital of at least $500
million 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 banks or trust companies so selected by the
Calculation Agent are not quoting as mentioned in this sentence, the Prime Rate
determined as of such Prime Rate Interest Determination Date will be the Prime
Rate in effect on such Prime Rate interest Determination Date.
 
    "Reuters Screen USPRIME1 Page" means the display on the Reuter Monitor Money
Rates Service (or any successor service) on the "USPRIME1" page (or any other
page as may replace such page on that service) for the purpose of displaying
prime rates or base lending rates of major United States banks.
 
    CD RATE NOTES
 
    Each CD Rate Note will bear interest at the interest rate (calculated with
reference to the CD Rate and the Spread or Spread Multiplier, if any) specified
on the face of such CD Rate Note and in the applicable Pricing Supplement.
 
    Unless otherwise indicated in the applicable Pricing Supplement, "CD Rate"
means, with respect to any CD Rate Interest Determination Date, the rate on such
date for negotiable certificates of deposit having the Index Maturity specified
in the applicable Pricing Supplement as published in H.15(519) under the heading
"CDs (Secondary Market)." In the event that such rate is not published prior to
3:00 p.m., New York City time, on the Calculation Date pertaining to such CD
Rate Interest Determination Date, then the CD Rate shall be the rate on such CD
Rate Interest Determination Date for negotiable certificates of deposit having
the Index Maturity specified in the applicable Pricing Supplement as published
in Composite Quotations under the heading "Certificates of Deposit." If by 3:00
p.m., New York City time, on such Calculation Date such rate is not yet
published in either H.15(519) or Composite Quotations, the CD Rate for that CD
Interest Determination Date shall be calculated by the Calculation Agent and
shall be the arithmetic mean (rounded upwards, if necessary, to the next higher
one-hundred thousandth of a percentage point) of the secondary market offered
rates, as of 10:00 a.m., New York City time, on that CD Rate Interest
Determination Date, of three leading nonbank dealers of negotiable U.S. dollar
certificates of deposit in The City of New York selected by the Calculation
Agent for negotiable certificates of deposit of major United States money market
banks with a remaining maturity closest to the Index Maturity specified in the
applicable Pricing Supplement in a denomination of $5,000,000; PROVIDED,
HOWEVER, that if fewer than three dealers selected as aforesaid by the
Calculation Agent are quoting as mentioned in this sentence, the CD Rate will be
the CD Rate in effect on such CD Rate Interest Determination Date.
 
    FEDERAL FUNDS RATE NOTES
 
    Each Federal Funds Rate Note will bear interest at the interest rate
(calculated with reference to the Federal Funds Rate and the Spread or Spread
Multiplier, if any) specified on the face of such Federal Funds Rate Note and in
the applicable Pricing Supplement.
 
                                      S-10
<PAGE>
    LIBOR NOTES
 
    Each LIBOR Note will bear interest at the interest rate (calculated with
reference to LIBOR and the Spread or Spread Multiplier, if any) specified on the
face of such LIBOR Note and in the applicable Pricing Supplement.
 
    Unless otherwise indicated in the applicable Pricing Supplement, LIBOR will
be determined by the Calculation Agent in accordance with the following
provisions: On each LIBOR Interest Determination Date, LIBOR will be determined
on the basis of the offered rate for deposits in U.S. dollars having the Index
Maturity specified in the applicable Pricing Supplement, commencing on the
second London Business Day immediately following such LIBOR Interest
Determination Date, which appears on the Telerate Page 3750 as of 11:00 a.m.,
London time, on that LIBOR Interest Determination Date. If such rate does not so
appear on the Telerate Page 3750, the rate in respect of such LIBOR Interest
Determination Date will be determined on the basis of the rates at which
deposits in U.S. dollars are offered by four major banks in the London interbank
market (selected by the Calculation Agent) at approximately 11:00 a.m., London
time, on the LIBOR Interest Determination Date next preceding the relevant
Interest Reset Date to prime banks in the London interbank market for a period
of the Index Maturity commencing on that Interest Reset Date and in a principal
amount equal to an amount not less than $1,000,000 that is representative for a
single transaction in such market at such time. In such case, the Calculation
Agent will request the principal London office of each of the aforesaid major
banks to provide a quotation of such rate. If at least two such quotations are
provided in respect of such LIBOR Interest Determination Date, the rate for that
Interest Rate Date will be the arithmetic mean of the quotations, and, if fewer
than two quotations are provided as requested in respect of such LIBOR Interest
Determination Date, the rate for that Interest Reset Date will be the arithmetic
mean of the rates quoted by three major banks in The City of New York, selected
by the Calculation Agent, at approximately 11:00 a.m., New York City time, on
that LIBOR Interest Determination Date for loans in U.S. dollars to leading
European banks for a period of the Index Maturity commencing on that Interest
Reset Date and in a principal amount equal to an amount not less than $1,000,000
that is representative for a single transaction in such market at such time;
PROVIDED, HOWEVER, if the aforesaid rate cannot be determined by the Calculation
Agent, LIBOR in respect of such LIBOR Interest Determination Date will be LIBOR
then in effect on such LIBOR Interest Determination Date.
 
    TREASURY RATE NOTES
 
    Each Treasury Rate Note will bear interest at the interest rate (calculated
with reference to the Treasury Rate and the Spread or Spread Multiplier, if
any), and will be payable on the dates, specified on the face of such Note and
in the applicable Pricing Supplement.
 
    Unless otherwise indicated in the applicable Pricing Supplement, "Treasury
Rate" means, with respect to any Treasury Interest Determination Date, the rate
for the most recent auction of direct obligations of the United States
("Treasury bills") having the Index Maturity specified in the applicable Pricing
Supplement as published in H.15(519) under the heading, "U.S. Government
Securities/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 auction average rate
(expressed as a bond equivalent, rounded, upwards if necessary, to the next
higher one hundred thousandth of a percentage point, on the basis of a year of
365 or 366 days, as applicable, and applied on a daily basis) for such auction
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 Index
Maturity specified in the applicable Pricing Supplement are not published or
reported as provided above by 3:00 p.m., New York City time, on such Calculation
Date, or if no such auction is held in a particular week, then the Treasury Rate
shall be the rate as published in H.15(519) under the heading "U.S. Government
Securities/Treasury Bills/Secondary Market." In the event that such rate is not
so published by 3:00 p.m., New York City time, on such Calculation Date, then
the Treasury Rate shall be calculated by the Calculation Agent and shall be a
yield to maturity (expressed as a bond equivalent rounded, upwards if necessary,
to the next higher one hundred thousandth of a percentage point, on the basis of
a year of 365 or 366 days, as applicable, and applied on a daily basis) of the
arithmetic mean, as calculated by the Calculation Agent on such Calculation
Date, of the secondary market bid rates as of
 
                                      S-11
<PAGE>
approximately 3:30 p.m., New York City time, on such Treasury Interest
Determination Date, of three leading primary United States government securities
dealers in The City of New York selected by the Calculation Agent, for the issue
of Treasury bills with a remaining maturity closest to the specified Index
Maturity; PROVIDED, HOWEVER, that if the dealers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Treasury
Rate will be the Treasury Rate in effect on such Treasury Interest Determination
Date.
 
BOOK-ENTRY NOTES
 
    Upon issuance, all Book-Entry Notes of like tenor having the same original
issuance date, interest rate, redemption provisions, if any, and Stated
Maturity, will be represented by a single Global Note. Each Global Note
representing Book-Entry Notes will be deposited with, or on behalf of, the
Depository, located in the Borough of Manhattan, The City of New York, and
registered in the name of a nominee of the Depository.
 
    Ownership of beneficial interests in a Global Note representing Book-Entry
Notes will be limited to institutions that have accounts with the Depository or
its nominee ("participants") or persons that may hold interests through
participants. In addition, ownership of beneficial interests by participants in
such a Global Note will only be evidenced by, and the transfer of that ownership
interest will only be effected through, records maintained by the Depository or
its nominee for such Global Note. Ownership of beneficial interests in such a
Global Note by persons that hold through participants will only be evidenced by,
and the transfer of that ownership interest will only be effected through,
records maintained by such participant. The laws of some jurisdictions require
that certain purchasers of securities take physical delivery of such securities
in definitive form. Such laws may impair the ability to transfer beneficial
interests in such a Global Note.
 
    The Company has been advised by the Depository that upon the issuance of a
Global Note representing Book-Entry Notes, and the deposit of such Global Note
with the Depository, the Depository will immediately credit, on its book-entry
registration and transfer systems, the respective principal amounts of the
Book-Entry Notes represented by such Global Note to the accounts of
participants. The accounts to be credited shall be designated by the Agents or,
to the extent that the Book-Entry Notes are offered and sold directly, by the
Company.
 
    Payment of principal of, premium, if any, and interest on Book-Entry Notes
represented by any Global Note registered in the name of or held by the
Depository or its nominee will be made to the Depository or its nominee, as the
case may be, as the registered owner and Holder of the Global Note representing
such Book-Entry Notes. None of the Company, the Trustee or any agent of the
Company or the Trustee will have any responsibility or liability for any aspect
of the Depository's records or any participant's records relating to, or
payments made on account of, beneficial ownership interests in a Global Note
representing such Book-Entry Notes or for maintaining, supervising or reviewing
any of the Depository's records or any participant's records relating to such
beneficial ownership interests.
 
    The Company has been advised by the Depository that upon receipt of any
payment of principal of, premium, if any, or interest in respect of a Global
Note, the Depository will immediately credit, on its book-entry registration and
transfer system, accounts of participants with payments in amounts proportionate
to their respective beneficial interest in the principal amount of such Global
Note as shown on the records of the Depository. Payments by participants to
owners of beneficial interests in a Global Note held through such participants
will be governed by standing instructions and customary practices, as is now the
case with securities held for the accounts of customers registered in "street
name," and will be the sole responsibility of such participants.
 
    No Global Note described above may be transferred except as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
another nominee of the Depository.
 
    A Global Note representing Book-Entry Notes is exchangeable for definitive
Notes in registered form, of like tenor and of an equal aggregate principal
amount, only if (x) the Depository notifies the Company that it is unwilling or
unable to continue as Depository for such Global Note or if at any time the
Depository ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended (the
 
                                      S-12
<PAGE>
"Exchange Act"), (y) the Company in its sole discretion determines that such
Global Note shall be exchangeable for definitive Notes in registered form or (z)
any event shall have happened and be continuing which, after notice or lapse of
time, or both, would be an Event of Default with respect to the Notes. Any
Global Note that is exchangeable pursuant to the preceding sentence shall be
exchangeable in whole for definitive Notes in registered form, of like tenor and
of an equal aggregate principal amount, in denominations of $50,000 and integral
multiples of $1,000 in excess thereof. Such definitive Notes shall be registered
in the name or names of such person or persons as the Depository shall instruct
the Trustee. It is expected that such instructions may be based upon directions
received by the Depository from its participants with respect to ownership of
beneficial interests in such Global Note.
 
    Except as provided above, owners of beneficial interests in such Global Note
will not be entitled to receive physical delivery of Notes in definitive form
and will not be considered the Holders thereof for any purpose under the
Indenture, and no Global Note representing Book-Entry Notes shall be
exchangeable, except for another Global Note of like denomination and tenor to
be registered in the name of the Depository or its nominee. Accordingly, each
person owning a beneficial interest in such Global Note must rely on the
procedures of the Depository and, if such person is not a participant, on the
procedures of the participant through which such person owns its interest, to
exercise any rights of a Holder under the Indenture. The Indenture allows the
Depository, as a Holder, to appoint agents and otherwise authorize participants
to give or take any request, demand, authorization, direction, notice, consent,
waiver or other action which a Holder is entitled to give or take under the
Indenture. The Company understands that under existing industry practices, in
the event that the Company requests any action of Holders or an owner of a
beneficial interest in such permanent Global Note desires to give or take any
action that a Holder is entitled to give or take under the Indenture, the
Depository would authorize the participants holding the relevant beneficial
interests to give or take such action, and such participants would authorize
beneficial owners owning through such participants to give or take such action
or would otherwise act upon the instructions of beneficial owners owning through
them.
 
    The Depository has advised the Company and the Agents as follows: The
Depository is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Depository was created to hold securities of its participants
and to facilitate the clearance and settlement of securities transactions among
its participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates. The Depository's participants include securities
brokers and dealers (including the Agents), banks, trust companies, clearing
corporations, and certain other organizations, some of whom (and/or their
representatives) own the Depository. Access to the Depository's book-entry
system is also available to others, such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.
 
             SPECIAL PROVISIONS RELATING TO FOREIGN CURRENCY NOTES
 
GENERAL
 
    Unless otherwise indicated in the applicable Pricing Supplement, the Notes
will be denominated in U.S. dollars and payments of principal of, premium, if
any, and interest on the Notes will be made in U.S. dollars. If any of the Notes
are to be denominated in a currency or currency unit other than U.S. dollars,
the following provisions shall apply, which are in addition to, and to the
extent inconsistent therewith replace, the description of general terms and
provisions of Notes set forth in the accompanying Prospectus and elsewhere in
this Prospectus Supplement. For a description of certain risks associated with
Foreign Currency Notes, see "Foreign Currency Risks."
 
    THIS PROSPECTUS SUPPLEMENT, THE ACCOMPANYING PROSPECTUS AND ANY PRICING
SUPPLEMENT DO NOT DESCRIBE ALL RISKS OF AN INVESTMENT IN FOREIGN CURRENCY NOTES
THAT RESULT FROM SUCH NOTES BEING DENOMINATED IN A FOREIGN
 
                                      S-13
<PAGE>
CURRENCY OR CURRENCY UNIT EITHER AS SUCH RISKS EXIST AT THE DATE OF THIS
PROSPECTUS SUPPLEMENT OR AS SUCH RISKS MAY CHANGE FROM TIME TO TIME. PROSPECTIVE
PURCHASERS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL ADVISORS AS TO THE RISKS
ENTAILED IN AN INVESTMENT IN FOREIGN CURRENCY NOTES AND AS TO ANY MATTERS THAT
MAY AFFECT THE PURCHASE OR HOLDING OF A FOREIGN CURRENCY NOTE OR THE RECEIPT OF
PAYMENTS OF PRINCIPAL OF AND ANY PREMIUM AND INTEREST ON A FOREIGN CURRENCY NOTE
IN A SPECIFIED CURRENCY. FOREIGN CURRENCY NOTES ARE NOT AN APPROPRIATE
INVESTMENT FOR INVESTORS WHO ARE UNSOPHISTICATED WITH RESPECT TO FOREIGN
CURRENCY TRANSACTIONS.
 
    Unless otherwise indicated in the applicable Pricing Supplement, a Foreign
Currency Note will not be sold in, or to a resident of, the country of the
Specified Currency in which such Note is denominated.
 
    Foreign Currency Notes are issuable in registered form only, without
coupons. The denominations for particular Foreign Currency Notes will be
specified in the applicable Pricing Supplement.
 
    Unless otherwise provided in the applicable Pricing Supplement, payment of
the purchase price of Foreign Currency Notes will be made in immediately
available funds.
 
    The information set forth in this Prospectus Supplement is directed to
prospective purchasers of Notes who are United States residents, and the Company
disclaims any responsibility to advise prospective purchasers who are residents
of countries other than the United States with respect to any matters that may
affect the purchase or holding of, or receipt of payments of principal, premium
or interest in respect of, Notes. Such persons should consult their own advisors
with regard to such matters.
 
CURRENCIES
 
    Unless otherwise specified in the applicable Pricing Supplement, purchasers
are required to pay for Foreign Currency Notes in the currency or currency unit
specified in the applicable Pricing Supplement (the "Specified Currency"). At
the present time there are limited facilities in the United States for the
conversion of U.S. dollars into the Specified Currencies and vice versa, and
banks do not offer non--U.S. dollar checking or savings account facilities in
the United States. However, if requested on or prior to the fifth Business Day
preceding the date of delivery of the Notes, or by such other day as determined
by the Agent who presented such offer to purchase Notes to the Company, such
Agent is prepared to arrange for the conversion of U.S. dollars into the
Specified Currency set forth in the applicable Pricing Supplement to enable the
purchasers to pay for the Notes. Each such conversion will be made by the
applicable Agent on such terms and subject to such conditions, limitations and
charges as the applicable Agent may from time to time establish in accordance
with its regular foreign exchange practices. All costs of exchange will be borne
by the purchasers of the Notes.
 
    Specific information about the foreign currency or currency units in which a
particular Foreign Currency Note is denominated, including historical exchange
rates and a description of the currency and any exchange controls, will be
contained in the applicable Pricing Supplement. Such information contained
therein shall be furnished as a matter of information only and should not be
regarded as indicative of the range of or trends in fluctuations in currency
exchange rates that may occur in the future. See "Foreign Currency Risks --
Exchange Rates and Exchange Controls."
 
PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST
 
    The principal of, premium, if any, and interest on Foreign Currency Notes
are payable by the Company in the Specified Currency. Unless otherwise specified
in the applicable Pricing Supplement, since banks do not now have non-U.S.
dollar bank accounts in their offices in the United States, the Exchange Rate
Agent will convert all payments of principal of and interest on Foreign Currency
Notes to U.S. dollars. However, unless otherwise specified in the applicable
Pricing Supplement, the Holder of a Foreign Currency Note may elect to receive
such payments in the Specified Currency as described below.
 
                                      S-14
<PAGE>
    Any U.S. dollar amount to be received by a Holder of a Foreign Currency Note
will be based on the highest bid quotation in The City of New York received by
the Exchange Rate Agent at approximately 11:00 a.m., New York City time, on the
second Business Day preceding the applicable payment date from three recognized
foreign exchange dealers (one of which may be the Exchange Rate Agent) selected
by the Exchange Rate Agent and approved by the Company for the purchase by the
quoting dealer of the Specified Currency for U.S. dollars for settlement on such
payment date in the aggregate amount of the Specified Currency payable to all
Holders of Foreign Currency Notes scheduled to receive U.S. dollar payments and
at which the applicable dealer commits to execute a contract. If such bid
quotations are not available, payments will be made in the Specified Currency.
All currency exchange costs will be borne by the Holder of the Foreign Currency
Note by deductions from such payments.
 
    Notwithstanding the foregoing, unless otherwise specified in the applicable
Pricing Supplement, a Holder of Foreign Currency Notes may elect to receive
payment of the principal of, premium, if any, and interest on the Notes in the
Specified Currency by transmitting a written request for such payment to the
principal offices of The Chase Manhattan Bank in the Borough of Manhattan, The
City of New York, as Paying Agent, on or prior to the Regular Record Date or at
least sixteen days prior to maturity, as the case may be. Such request may be in
writing (mailed or hand delivered) or by cable, telex or other form of facsimile
transmission. A Holder of a Foreign Currency Note may elect to receive payment
in the Specified Currency for all principal, premium, if any, and interest
payments and need not file a separate election for each payment. Such election
will remain in effect until revoked by written notice to The Chase Manhattan
Bank in the Borough of Manhattan, The City of New York, but written notice of
any such revocation must be received by The Chase Manhattan Bank in the Borough
of Manhattan, The City of New York on or prior to the relevant Regular Record
Date or at least sixteen days prior to the maturity date, as the case may be.
Holders of Foreign Currency Notes whose Foreign Currency Notes are to be held in
the name of a broker or nominee should contact such broker or nominee to
determine whether and how an election to receive payments in the Specified
Currency may be made.
 
    Unless otherwise specified in the applicable Pricing Supplement, a
beneficial owner of Book-Entry Notes denominated in a Specified Currency
electing to receive payments of principal or any premium or interest in the
Specified Currency must notify the participant through which its interest is
held on or prior to the applicable Regular Record Date or at least sixteen days
prior to maturity, as the case may be, of such beneficial owner's election to
receive all or a portion of such payment in a Specified Currency. Such
participant must notify the Depository of such election on or prior to the third
Business Day after such Regular Record Date. The Depository will notify the
Paying Agent of such election on or prior to the fifth Business Day after such
Regular Record Date. If complete instructions are received by the participant
and forwarded by the participant to the Depository, and by the Depository to the
Paying Agent, on or prior to such dates, the beneficial owner will receive
payments in the Specified Currency.
 
    Interest on Foreign Currency Notes paid in U.S. dollars will be paid in the
manner specified in the accompanying Prospectus and this Prospectus Supplement
for interest on Notes denominated in U.S. dollars. Interest on Foreign Currency
Notes paid in the Specified Currency will be paid by a check drawn on account
maintained at a bank outside the United States, unless other arrangements have
been made. The principal of Foreign Currency Notes, together with interest
accrued and unpaid thereon, due at maturity will be paid in immediately
available funds against presentation of such Foreign Currency Notes at the
principal offices of The Chase Manhattan Bank in the Borough of Manhattan, The
City of New York, as Paying Agent. Any payment of principal or interest required
to be made on an Interest Payment Date or at maturity of a Foreign Currency Note
which is not a Business Day need not be made on such day, but may be made on the
next succeeding Business Day with the same force and effect as if made on the
Interest Payment Date or at maturity, as the case may be, and no interest shall
accrue for the period from and after such Interest Payment Date or maturity.
 
PAYMENT CURRENCY
 
    If a Specified Currency is not available for the payment of principal,
premium, if any, or interest with respect to a Foreign Currency Note due to the
imposition of exchange controls or other circumstances
 
                                      S-15
<PAGE>
beyond the control of the Company, the Company will be entitled to satisfy its
obligations to Holders of Foreign Currency Notes by making such payment in U.S.
dollars on the basis of the Market Exchange Rate on the date of such payment, or
if such Market Exchange Rate is not then available, on the basis of the most
recently available Market Exchange Rate. See "Foreign Currency Risks -- Exchange
Rates and Exchange Controls."
 
                             FOREIGN CURRENCY RISKS
 
GENERAL
 
    EXCHANGE RATES AND EXCHANGE CONTROLS
 
    An investment in Foreign Currency Notes entails significant risks that are
not associated with a similar investment in a security denominated in U.S.
dollars. Such risks include, without limitation, the possibility of significant
changes in the rate of exchange between the U.S. dollar and the Specified
Currency and the possibility of the imposition or modification of foreign
exchange controls by either the United States or foreign governments. Such risks
generally depend on economic and political events over which the Company has no
control. In recent years, rates of exchange between the U.S. dollar and certain
foreign currencies have been highly volatile and such volatility may be expected
in the future. Fluctuations in any particular exchange rate that have occurred
in the past are not necessarily indicative, however, of fluctuations in the rate
that may occur during the term of any Foreign Currency Note. Depreciation of the
Specified Currency applicable to a Foreign Currency Note against the U.S. dollar
would result in a decrease in the U.S. dollar-equivalent yield of such Note, in
the U.S. dollar-equivalent value of the principal repayable at maturity of such
Note and, generally, in the U.S. dollar-equivalent market value of such Note.
 
    JUDGMENTS
 
    In the event an action based on Foreign Currency Notes were commenced in a
court of the United States, it is likely that such court would grant judgment
relating to such Notes only in U.S. dollars. It is not clear, however, whether,
in granting such judgment, the rate of conversion into U.S. dollars would be
determined with reference to the date of default, the date judgment is rendered
or some other date.
 
    EXCHANGE CONTROLS, ETC.
 
    Governments have imposed from time to time exchange controls and may in the
future impose or revise exchange controls at or prior to a Note's maturity. Even
if there are not exchange controls, it is possible that the Specified Currency
for any particular Foreign Currency Note would not be available at such Note's
maturity. In that event, the Company will pay in U.S. dollars on the basis of
the Market Exchange Rate on the date of such payment, or if such Market Exchange
Rate is not then available, on the basis of the most recently available Market
Exchange Rate.
 
                             UNITED STATES TAXATION
 
GENERAL
 
    The following is a summary of certain United States federal income tax
consequences to initial purchasers of an investment in the Notes. The summary
does not discuss all aspects of federal income taxation which may be relevant to
particular investors in light of their specific investment circumstances, nor
does it discuss any foreign, state or local income or other tax considerations.
The summary is based upon the Internal Revenue Code of 1986, as amended (the
"Code"), and on regulations, rulings and decisions that are in effect as of the
date of this Prospectus, all of which are subject to change possibly with
retroactive effect.
 
    The summary assumes that the Notes are held as "capital assets" (generally,
property held for investment purposes) within the meaning of Section 1221 of the
Code and are purchased at a price equal to their stated principal amount or, in
the case of Original Isssue Discount Notes, their issue price. Except to the
extent discussed below under the heading "United States Taxation -- Non-U.S.
Holders" this summary may not be applicable to holders of Notes that are not
U.S. Holders. A "U.S. Holder" means a beneficial owner of a Note that is for
federal income tax purposes (i) a citizen or resident of the United States, (ii)
a
 
                                      S-16
<PAGE>
corporation, partnership or other entity created or organized in or under the
laws of the United States or any political subdivision thereof, or (iii) an
estate or trust the income of which is subject to United States federal income
taxation regardless of its source.
 
    PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT THEIR TAX ADVISORS REGARDING
THE FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES OF AN
INVESTMENT IN THE NOTES.
 
STATED INTEREST
 
    In general, interest payments on a Note calculated on the basis of a single
fixed rate of interest, or a variable rate tied to a single objective index of
market interest rates, that is actually and unconditionally payable at fixed
periodic intervals of one year or less over the entire term of the Note
(including short periods) will be includable in the U.S. Holder's gross income
as ordinary interest income in accordance with such holder's method of tax
accounting.
 
ORIGINAL ISSUE DISCOUNT
 
    A Note may be issued with original issue discount for federal income tax
purposes. Original issue discount will arise if the stated principal amount at
maturity of a Note exceeds its issue price by more than a DE MINIMIS amount, or
if a Note has certain interest payment characteristics (e.g., interest holidays,
interest payable in additional Notes, stepped rates or rates based on multiple
indices). If a Note is issued with original issue discount, the holder of the
Note may be required to include amounts in gross income for federal income tax
purposes in advance of the receipt of the cash payment to which such income is
attributable. The amount of original issue discount to be included in income in
any tax period will be determined using a constant yield to maturity method.
 
    Any Note issued with original issue discount will bear a legend setting
forth the total amount of original issue discount with respect to such Note, and
the Company will report annually to the Internal Revenue Service (the "IRS") and
to each holder of such Note the original issue discount accrued with respect to
the Note. Prospective holders are advised to consult their tax advisors with
respect to the particular original issue discount characteristics of the Note
that is being purchased.
 
SALE, EXCHANGE OR RETIREMENT OF NOTES
 
    In general, and subject to the foregoing, an initial holder of a Note will
recognize capital gain or loss on the sale, exchange or retirement of a Note
measured by the difference between the amount of cash received (except to the
extent attributable to accrued interest) and the holder's adjusted tax basis in
the Note. A U.S. Holder's adjusted tax basis in a Note is generally equal to the
amount paid for such Note increased by the amount of original issue discount
previously taken into income.
 
FOREIGN CURRENCY NOTES
 
    For purposes of the following discussion, it is assumed that the functional
currency of a U.S. Holder is the U.S. dollar.
 
    INTEREST PAYMENTS AND ORIGINAL ISSUE DISCOUNT
 
    In general, interest on a Foreign Currency Note (whether received in the
Specified Currency or U.S. dollars) will be taxable to a U.S. Holder as ordinary
interest income at the time it is accrued or received in accordance with such
holder's method of accounting for tax purposes. Regardless of whether an
interest payment is in fact converted to U.S. dollars, the amount of interest
income (including any original issue discount) required to be included in income
(the "Includible Amount") will generally be (i) in the case of a cash basis
taxpayer, the U.S. dollar value of the foreign currency interest payment based
on the exchange rate in effect on the date of receipt or payment plus the amount
of any accrued original issue discount required to be included in income (as
calculated below) and (ii) in the case of an accrual basis taxpayer, the U.S.
dollar value of the accrued amounts based on (x) the average exchange rate in
effect during the interest accrual period or (y) if an election is made under
Treasury Regulation Section 1.988-2(b)(2)(iii) (the "Section 988 Election"), the
exchange rate on the last day of the interest accrual period or, if such date is
within five business days of the last day of the interest accrual period, on the
date of the receipt of the interest
 
                                      S-17
<PAGE>
payment. The amount of original issue discount on a Foreign Currency Note
required to be included in income for a cash basis taxpayer will be computed for
any accrual period in the relevant foreign currency and then translated into a
U.S. dollar value based on (i) the average exchange rate in effect during such
accrual period or (ii) if a Section 988 Election is made, the exchange rate on
the last day of the interest accrual period or, if such date is within five
business days of the last day of the interest accrual period, on the date of the
receipt of the interest payment. The Section 988 Election is made by filing a
statement with the holder's first return for a taxable year in which the Section
988 Election is effective. The Section 988 Election must be applied consistently
to all debt instruments held by such holder and cannot be changed without the
consent of Commissioner of the IRS.
 
    An accrual basis taxpayer will be required to recognize gain or loss upon
the receipt of interest payments on a Foreign Currency Note attributable to
fluctuations in currency exchange rates ("Foreign Currency Exchange Gain or
Loss") between the dates of accrual and receipt, equal to the difference, if
any, between (i) the U.S. dollar value of the Specified Currency interest
payment based on the exchange rate in effect on the date of receipt and (ii) the
Includible Amount. Any such Foreign Currency Exchange Gain or Loss will be
ordinary income or loss. Rules similar to those described above with respect to
accrual basis taxpayers apply to both cash and accrual basis holders of Foreign
Currency Notes that are issued with original issue discount.
 
    PURCHASE, SALE, EXCHANGE AND RETIREMENT OF FOREIGN CURRENCY NOTES
 
    A U.S. Holder's tax basis in a Foreign Currency Note will be (i) the U.S.
dollar value of the Specified Currency amount paid for such Foreign Currency
Note based on the exchange rate in effect on the date of purchase of the Foreign
Currency Note plus (ii) the U.S. dollar value of any accrued original issue
discount on the Foreign Currency Note which the U.S. Holder has reported in
gross income. A holder who converts U.S. dollars to a foreign currency and
immediately uses that currency to purchase a Foreign Currency Note denominated
in the same currency will ordinarily not recognize Foreign Currency Exchange
Gain or Loss in connection with such conversion and purchase. If a U.S. Holder
purchases a Foreign Currency Note with previously owned foreign currency, such
holder will recognize Foreign Currency Exchange Gain or Loss in an amount equal
to the difference, if any, between the U.S. Holder's tax basis in such foreign
currency and the U.S. dollar fair market value of the Foreign Currency Note
based on the exchange rate in effect on the date of purchase.
 
    Gain or loss will be recognized upon the sale, exchange or retirement of a
Foreign Currency Note equal to the U.S. dollar value of the foreign currency
received upon such disposition less the U.S. dollar tax basis in the Foreign
Currency Note. Such gain or loss will be ordinary income or loss to the extent
it is treated as Foreign Currency Exchange Gain or Loss. Any gain or loss that
is recognized in excess of Foreign Currency Exchange Gain or Loss will be
capital gain or loss.
 
    EXCHANGE OF FOREIGN CURRENCY
 
    Foreign currency received as interest on a Foreign Currency Note or on the
sale or retirement of a Foreign Currency Note will have a tax basis equal to its
U.S. dollar value determined at the time such interest is received or at the
time of sale or retirement. Any gain or loss recognized on a sale or other
disposition of the foreign currency will be ordinary income or loss.
 
NON-U.S. HOLDERS
 
    Under present United States federal income and estate tax law and subject to
the discussion of backup withholding below:
 
           (a)
           payments of interest (including any original issue discount, if any)
           on the Notes to a Non-U.S. Holder will not be subject to federal
    income or withholding tax, provided that (1) the holder does not actually or
    constructively own 10% or more of the total combined voting power of all
    classes of stock of the Company entitled to vote, (2) the holder is not (i)
    a bank receiving interest pursuant to a loan agreement entered into in the
    ordinary course of its trade or business or (ii) a controlled foreign
    corporation that is related to the Company through stock ownership, (3) such
    interest payments are not effectively connected with a United States trade
    or business of the holder and (4) either (i) the holder
 
                                      S-18
<PAGE>
    certifies to the Company or its agent, under penalties of perjury, that it
    is not a United States person and provides its name and address or (ii) a
    securities clearing organization, bank or other financial institution which
    holds the Notes and customers' securities in the ordinary course of its
    trade or business (a "financial institution") certifies to the Company or
    its agent under penalties of perjury that such statement has been received
    by it from the holder (or by a financial institution between it and the
    holder) and furnishes the payor with a copy thereof;
 
           (b)
           a Non-U.S. Holder will not be subject to federal income tax on gain
           realized on the sale, exchange, retirement or other disposition of a
    Note, unless (1) such holder is an individual who is present in the United
    States for 183 days or more during the taxable year and certain requirements
    are met or (2) the gain is effectively connected with a United States trade
    or business of the Non-U.S. Holder; and
 
           (c)
           a Note held by an individual who at the time of death is not a
           citizen or resident of the United States for federal estate tax
    purposes will not be subject to federal estate tax as a result of such
    individual's death unless (1) the income from the Note is effectively
    connected with a United States trade or business of the Non-U.S. Holder or
    (2) the individual actually or constructively owns 10% or more of the total
    combined voting power of all classes of stock of the Company entitled to
    vote.
    A Non-U.S. Holder which is a foreign corporation may be subject to a branch
profits tax equal to 30% of its effectively connected earnings and profits for
the taxable year, subject to certain adjustments, unless it qualifies for a
lower rate under an applicable tax treaty. For this purpose, interest (including
original issue discount) on a Note will be included in earnings and profits if
such interest is effectively connected with the conduct by the foreign
corporation of a trade or business in the United States.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    Interest paid with respect to a Note, and payment of the proceeds from sale
of a Note to or through a United States office of a broker, received by a
Non-U.S. Holder will not be subject to information reporting and backup
withholding if the payor has received the appropriate certification statement.
The appropriate certification procedures require that the Non-U.S. Holder
certify as to its status as a Non-U.S. Holder and provide its name and address.
In addition, payments of the proceeds from the sale of a Note to or through a
foreign office of a broker or the foreign office of a custodian, nominee or
other agent acting on behalf of the beneficial owner of a Note will not be
subject to information reporting or backup withholding; however, if the broker,
custodian, nominee or other agent is a United States person, a controlled
foreign corporation for federal income tax purposes or a foreign person 50% or
more of whose gross income, over a specified three-year period, is from a United
States trade or business, information reporting may be required with respect to
such payments.
 
    Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder would be allowed as a refund or a credit against such
Non-U.S.Holder's federal income tax liability, provided that the required
information is furnished to the IRS.
 
NEW PROPOSED WITHHOLDING REGULATIONS
 
    On April 22, 1996, the IRS issued proposed regulations (the "Proposed
Regulations"), which, if enacted in their current form, could affect the
procedures to be followed by a Non-U.S. Holder in establishing such holder's
status as a Non-U.S. Holder for purposes of the withholding rules (including the
backup withholding rules discussed above). The Proposed Regulations, if adopted
in their present form, generally would be effective for payments made after
December 31, 1997. Prospective investors should consult their tax advisors
concerning the potential adoption of the Proposed Regulations and the potential
effect of such regulations on an investment in the Notes.
 
                         PLAN OF DISTRIBUTION OF NOTES
 
    Under the terms of an Agency Agreement, dated August 15, 1996 (the "Agency
Agreement"), the Notes may be offered on a continuing basis by the Company
through the Agents, each of which has agreed to use reasonable efforts to
solicit purchases of the Notes. The Company will pay each Agent a commission
from
 
                                      S-19
<PAGE>
 .2% to .75% of the principal amount of each Note, depending on its Stated
Maturity, sold through such Agent. This commission scale applies to Notes that
mature between eighteen months and thirty years (inclusive) from their date of
issue. The commission applicable to the sale of any Note that matures more than
thirty years from its date of issue will be determined by the relevant Agent and
the Company at the time of such sale and disclosed in the applicable Pricing
Supplement. The Company has reserved the right to sell Notes directly or
indirectly to investors on its own behalf. The Company may accept offers to
purchase Notes through additional agents on substantially the same terms and
conditions (including commission rates) as would apply to purchases under the
Agency Agreement. Such other agents, if any, will be named in the applicable
Pricing Supplement. The Company will have the sole right to accept offers to
purchase Notes and may reject any such offer, in whole or in part. Each Agent
shall have the right, in its discretion reasonably exercised, without notice to
the Company, to reject any offer to purchase Notes received by it, in whole or
in part. The Company also may sell Notes to an Agent, acting as principal, at a
discount to be agreed upon at the time of sale, for resale to one or more
investors at varying prices related to prevailing market prices at the time of
such resale, as determined by such Agent. An Agent may sell Notes it has

                                  THE COMPANY
 
    The Company, a New York corporation incorporated in 1941 as the successor to
the  New York  corporation of the  same name  organized in 1898,  is a worldwide
producer of  printing and  writing  papers, paperboard  and packaging  and  wood
products; and distributes paper and office supply products in the United States,
Europe  and  the Pacific  Rim. It  also produces  pulp, laminated  products, and
specialty  products,  including  photosensitive  films  and  papers,  nonwovens,
chemicals and minerals.
 
    In  the United  States, the  Company operates  24 pulp  and paper  mills, 52
converting and  packaging  plants, 29  wood  products facilities,  15  specialty
panels  and  laminated products  plants  and six  nonwoven  products facilities.
Production facilities in Europe, Asia, Latin America and Canada include 14  pulp
and  paper  mills,  30  converting  and  packaging  plants,  two  wood  products
facilities, four  specialty  panels  and  laminated  products  plants  and  four
nonwoven products facilities.
 
    The  Company distributes  fine paper,  printing and  industrial products and
building materials, primarily manufactured by other companies, through over  300
distribution  branches located primarily in the  United States. In addition, the
Company produces  photosensitive films  and  papers and  photographic  equipment
(three  United States and  six international locations)  and specialty chemicals
(seven United States and three international locations), and engages in domestic
oil and gas and real estate activities.
 
    Through its ownership  of a  majority interest  in Carter  Holt Harvey,  the
Company,  primarily in New Zealand and Australia, operates seven mills producing
pulp and  paper, packaging  and  tissue products,  32 converting  and  packaging
facilities, 49 wood products manufacturing and distribution facilities, and nine
building  products plants.  Carter Holt  Harvey distributes  paper and packaging
products through 18 distribution branches located in New Zealand and  Australia.
In  New  Zealand, Carter  Holt Harvey  controls  approximately 800,000  acres of

    The Company, which owns a majority interest in IP Timberlands, Ltd., a Texas
limited partnership  ("IPT"),  controlled  approximately 6.0  million  acres  of

interest  in a subsidiary  partnership that owns  approximately 300,000 acres of
forestlands located in Oregon and Washington. Included in the net assets of  the
partnership  interest sold were forestlands, roads and $750 million of long-term
debt.
 
    On March 12, 1996, the Company completed the recently-announced merger  with
Federal, a diversified forest and paper products company. Under the terms of the
merger  agreement, Federal shareholders  received, at their  election subject to
certain limitations, either $55 in cash per share or $55 worth of  International
Paper  common  stock per  share.  To complete  the  merger, Federal  shares were
acquired  for  approximately  $1.3   billion  in  cash   and  $1.4  billion   in
International  Paper common  stock. The results  of Federal are  included in the
consolidated statement of earnings since March 12, 1996, and the March 31, 1996,
consolidated balance sheet includes the balances of Federal.

    For  purposes of computing the ratio  of earnings to fixed charges, earnings
include pre-tax  earnings  before an  extraordinary  charge and  the  cumulative
effect  of an  accounting change,  interest expense  and the  estimated interest
factor in  rent expense  (which, in  the opinion  of the  Company,  approximates
one-third  of rent expense),  and adjustments for  undistributed equity earnings
and the amortization  of capitalized  interest. Fixed  charges include  interest
incurred  (including amounts capitalized)  and the estimated  interest factor in
rent expense. Dividends on  the Company's $4 Preferred  Stock ($4 per share  per
annum) are insignificant and, as a result, for the years ended December 31, 1991
through  1995, the  ratios of earnings  to combined fixed  charges and preferred
stock dividends were the same as the ratios of earnings to fixed charges.
 
                                USE OF PROCEEDS
 
    Except as otherwise described in an accompanying Prospectus Supplement,  the
net  proceeds to be received from the sale of the Securities offered hereby will
be used for general corporate purposes.  The Company may also apply proceeds  to
expenditures for plant and equipment, and possibly for acquisitions of the stock
or  assets of  other companies,  for the repurchase  of shares  of the Company's
Common Stock  or  to retire  other  short-term or  long-term  indebtedness.  The
Company expects that it will continue to incur indebtedness from time to time.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The following description sets forth certain general terms and provisions of
the  Debt  Securities  to  which  any  Prospectus  Supplement  may  relate.  The
particular terms of the Debt Securities offered by any Prospectus Supplement and
the extent, if any, to which such  general provisions may not apply to the  Debt
Securities so offered will be described in the Prospectus Supplement relating to
such Debt Securities.
 
    The  Senior Debt Securities  will be issued under  an Indenture (the "Senior
Indenture"), to be  entered into  between the  Company and  The Chase  Manhattan
Bank,  N.A., as trustee. The Subordinated Debt Securities will be issued under a
separate Indenture (the  "Subordinated Indenture"), to  be entered into  between
the Company and The Chase Manhattan Bank, N.A., as trustee. The Senior Indenture
and  the Subordinated  Indenture are sometimes  referred to  collectively as the
"Indentures." Copies of the Senior Indenture and the Subordinated Indenture have
been filed as exhibits to the Registration Statement. The Chase Manhattan  Bank,
N.A.,  as  trustee  under  the  Senior  Indenture  and  under  the  Subordinated
Indenture, is referred to herein as the "Trustee."
 
    The following summaries of certain provisions of the Senior Debt Securities,
the Subordinated  Debt  Securities and  the  Indentures  do not  purport  to  be
complete  and are subject to,  and qualified in their  entirety by reference to,
all the provisions of  the Indenture applicable to  a particular series of  Debt
Securities,  including  the  definitions  therein  of  certain  terms.  Wherever
particular Sections, Articles or defined terms of the Indentures are referred to
herein or  in  a Prospectus  Supplement,  it  is intended  that  such  Sections,
Articles  or defined terms shall be incorporated by reference herein or therein,
as the case may be. Section and Article references used herein are references to
the applicable
 
                                       4
<PAGE>
Indenture. Except as otherwise indicated, the terms of the Senior Indenture  and
the  Subordinated  Indenture  are  identical.  Capitalized  terms  not otherwise
defined herein  shall  have  the  meanings  given  to  them  in  the  applicable
Indenture.
 
GENERAL
 
    The  Indentures  will  not  limit the  aggregate  principal  amount  of Debt
Securities which may be issued thereunder, and each Indenture provides that Debt
Securities may be issued thereunder from time  to time in one or more series  up
to  the aggregate amount  from time to  time authorized by  the Company for each
series. Unless otherwise specified in the Prospectus Supplement, the Senior Debt
Securities when issued will be  unsecured and unsubordinated obligations of  the
Company  and  will  rank  equally  and  ratably  with  all  other  unsecured and
unsubordinated indebtedness  of the  Company. The  Subordinated Debt  Securities
when  issued will be  subordinated in right  of payment to  the prior payment in
full of all Senior  Indebtedness (as defined in  the Subordinated Indenture)  of
the Company as described in the Prospectus Supplement applicable to the offering
of Subordinated Debt Securities.
 
    Reference  is made to  the Prospectus Supplement  relating to the particular
series of Debt  Securities offered thereby  for a description  of the  following

Securities;  (2)  whether  the Debt  Securities  are Senior  Debt  Securities or
Subordinated Debt Securities; (3) any limit on the aggregate principal amount of

global   form  or  in  the  form  of  Book-Entry  Securities  and,  if  so,  the
circumstances under  which any  such  global security  or global  securities  or
Book-Entry  Securities may  be exchanged for  Debt Securities  registered in the
name of,  and  any transfer  of  such global  or  Book-Entry Securities  may  be
registered  to,  a  Person  other  than the  depository  for  such  temporary or
permanent global securities  or Book-Entry  Securities or its  nominee; (5)  the
price  or prices  (expressed as a  percentage of the  aggregate principal amount
thereof) at which the Debt Securities will  be issued; (6) the date or dates  on
which  the Debt Securities will mature; (7) the rate or rates per annum at which
the Debt Securities will bear interest, if any, and the date from which any such
interest will accrue; (8) the Interest Payment Dates on which any such  interest
on the Debt Securities will be payable, the Regular Record Date for any interest
payable  on any Debt Securities which  are Registered Securities on any Interest
Payment Date and  the extent  to which,  or the  manner in  which, any  interest
payable  on a temporary global Security on an Interest Payment Date will be paid
if other than in the manner described under "Temporary Global Securities" below;
(9) any mandatory or  optional sinking fund or  analogous provisions; (10)  each
office  or agency  where, subject  to the terms  of the  applicable Indenture as

after which and the price or prices  at which the Debt Securities may,  pursuant
to  any optional or mandatory redemption provisions, be redeemed, in whole or in
part, and  the other  detailed terms  and  provisions of  any such  optional  or
mandatory  redemption provisions, which may include with respect to a particular
series or particular  Debt Securities within  a series, a  redemption option  of
Holders  upon certain conditions,  as defined in  the applicable Indenture; (12)
the denominations in which any  Debt Securities which are Registered  Securities
will  be  issuable,  if other  than  denominations  of $1,000  and  any integral
multiple thereof,  and  the denomination  or  denominations in  which  any  Debt
Securities  which  are Bearer  Securities will  be issuable,  if other  than the
denomination of  $5,000; (13)  the  currency or  currency  units of  payment  of
principal of and any premium and interest on the Debt Securities; (14) any index
used  to determine the  amount of payments  of principal of  and any premium and

determined;  (15) the terms and conditions, if  any, pursuant to which such Debt
Securities are convertible or exchangeable into a security or securities of  the
Company; and (16) any other terms of the Debt
 
                                       5
<PAGE>
Securities  not inconsistent  with the  provisions of  the applicable Indenture.
(Section 3.1)  Any such  Prospectus Supplement  will also  describe any  special
provisions  for  the payment  of  additional amounts  with  respect to  the Debt
Securities.
 
    Debt Securities may also be issued under the Indenture upon the exercise  of
Warrants. See "Description of Warrants."
 
    Debt  Securities may  be issued  as Original  Issue Discount  Securities. An
Original Issue Discount Security is  a Debt Security, including any  Zero-Coupon
Security,  which is  issued at a  price lower  than the amount  payable upon the
Stated Maturity thereof and which provides that upon redemption or  acceleration
of  the  maturity,  an amount  less  than  the amount  payable  upon  the Stated
Maturity, determined in accordance with the  terms of such Debt Security,  shall
become  due  and  payable.  Certain special  United  States  federal  income tax
considerations applicable to Debt Securities sold at an original issue  discount
will  be described in  the Prospectus Supplement  relating thereto. In addition,
certain special  United  States  federal  income  tax  or  other  considerations
applicable  to  any  Debt Securities  which  are  denominated in  a  currency or
currency unit  other  than  United  States  dollars  may  be  described  in  the
applicable Prospectus Supplement relating thereto.
 
FORM, EXCHANGE, REGISTRATION AND TRANSFER
 
    Debt  Securities of a  series may be  issuable in definitive  form solely as
Registered Securities,  solely  as  Bearer  Securities  or  as  both  Registered
Securities  and Bearer Securities.  Unless otherwise indicated  in an applicable
Prospectus Supplement, Bearer  Securities will have  interest coupons  attached.
(Section  2.1) The Indentures also will provide that Debt Securities of a series
may be issuable  in temporary  or permanent  global form  and may  be issued  as
Book-Entry  Securities  that  will  be  deposited with,  or  on  behalf  of, The
Depository Trust Company (the "Depository")  or another depository named by  the
Company  and identified in a Prospectus  Supplement with respect to such series.
(Sections 2.1 and 2.4) See "Global and Book-Entry Debt Securities."
 
    In connection with its  original issuance, no  Bearer Security (including  a
Debt  Security exchangeable for a  Bearer Security or a  Debt Security in global
form that is  either a Bearer  Security or exchangeable  for Bearer  Securities)
shall  be mailed or otherwise delivered to any location in the United States (as
defined under  "Limitations on  Issuance  of Bearer  Securities") and  a  Bearer
Security  may be delivered in connection with  its original issuance only if the
Person entitled to receive such Bearer Security furnishes written  certification
of  the  beneficial ownership  of the  Bearer Security  as required  by Treasury
Regulation Section 1.163-5(c)(2)(i)(D)(3). In the  case of a Bearer Security  in
permanent  global  form, such  certification must  be  given in  connection with
notation of  a  beneficial  owner's  interest therein  in  connection  with  the
original  issuance  of  such  Debt  Security.  (Section  3.3)  See  "Global  and
Book-Entry Securities" and "Limitations on Issuance of Bearer Securities."
 
    Registered  Securities  of  any  series  will  be  exchangeable  for   other
Registered  Securities  of the  same series  and of  a like  aggregate principal
amount and tenor  of different  authorized denominations. In  addition, if  Debt
Securities  of any series are issuable  as both Registered Securities and Bearer
Securities, at the option of the  Holder upon request confirmed in writing,  and
subject  to the terms  of the applicable Indenture,  Bearer Securities (with all
unmatured coupons, except as provided below, and all matured coupons in default)
of such  series will  be exchangeable  into Registered  Securities of  the  same
series  of any authorized denominations and of a like aggregate principal amount
and tenor. Bearer Securities surrendered  in exchange for Registered  Securities
between a Regular Record Date or a Special Record Date and the relevant date for
payment  of interest  shall be surrendered  without the coupon  relating to such
date for payment of interest  and interest accrued as of  such date will not  be
payable in respect of the Registered Security issued in exchange for such Bearer
Security,  but will  be payable only  to the Holder  of such coupon  when due in
accordance with the terms  of the applicable  Indenture. Bearer Securities  will
not  be issued in exchange for  Registered Securities. (Section 3.5) Each Bearer
Security, and any coupon attached thereto, other than a temporary global  Bearer
Security  will bear  the following legend:  "Any United States  person who holds
this obligation will be subject
 
                                       6
<PAGE>
to  limitations  under  the  United  States  income  tax  laws,  including   the
limitations  provided  in  Sections  165(j) and  1287(a)  of  the  United States
Internal Revenue Code." A Book-Entry Security may not be registered for transfer
or exchange (other than  as a whole by  the Depository to a  nominee or by  such
nominee  to such Depository) unless the  Depository or such nominee notifies the
Company that  it  is  unwilling or  unable  to  continue as  Depository  or  the
Depository ceases to be qualified as required by the applicable Indenture or the
Company  instructs the Trustee in accordance  with the applicable Indenture that
such Book-Entry Securities shall  be so registerable  and exchangeable or  there
shall  have occurred and be  continuing an Event of  Default with respect to the
Debt Securities evidenced  by such  Book-Entry Securities or  there shall  exist
such  other  circumstances,  if  any,  as may  be  specified  in  the applicable
Prospectus Supplement. (Section 3.5)
 
    Debt Securities  may  be  presented  for exchange  as  provided  above,  and
Registered  Securities may be  presented for registration  of transfer (with the
form of transfer endorsed thereon duly executed), at the office of the  Security
Registrar  or at the office of any  transfer agent designated by the Company for
such purpose with respect to any series of Debt Securities and referred to in an
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges  as described in the applicable  Indenture.
Such  transfer or exchange will be effected  upon the Security Registrar or such
transfer agent, as the case may be, being satisfied with the documents of  title
and  identity of the  person making the  request. The Company  has appointed the
Trustee as Security Registrar. (Section  3.5) If a Prospectus Supplement  refers
to  any  transfer  agents  (in addition  to  the  Security  Registrar) initially
designated by the  Company with respect  to any series  of Debt Securities,  the
Company  may at any time  rescind the designation of  any such transfer agent or
approve a change  in the location  through which any  such transfer agent  acts,
except  that, if Debt Securities  of a series are  issuable solely as Registered
Securities, the Company will  be required to maintain  a transfer agent in  each
Place  of  Payment for  such  series and,  if Debt  Securities  of a  series are
issuable as Bearer  Securities, the  Company will  be required  to maintain  (in
addition  to the Security Registrar) a transfer  agent in a Place of Payment for
such series  located outside  the United  States. The  Company may  at any  time
designate  additional  transfer  agents  with  respect  to  any  series  of Debt
Securities. (Section 10.2)
 
    In the event of any redemption in part, the Company shall not be required to
(i) issue, register the  transfer of or exchange  Debt Securities of any  series
during  a  period  beginning at  the  opening  of business  15  days  before any
selection of Debt Securities  of that series  to be redeemed  and ending at  the
close  of business on (A) if Debt Securities  of the series are issuable only as
Registered Securities, the day of mailing  of the relevant notice of  redemption
and  (B) if Debt Securities of the series are issuable as Bearer Securities, the
day of the first publication  of the relevant notice  of redemption or, if  Debt
Securities of the series are also issuable as Registered Securities and there is
no  publication, the mailing of the relevant notice of redemption; (ii) register
the transfer of or exchange any Registered Security, or portion thereof,  called
for  redemption, except the unredeemed portion  of any Registered Security being
redeemed in part; or (iii) exchange  any Bearer Security called for  redemption,
except to exchange such Bearer Security for a Registered Security of that series
and like tenor which is immediately surrendered for redemption. (Section 3.5)
 
PAYMENT AND PAYING AGENTS
 
    Unless  otherwise indicated in an  applicable Prospectus Supplement, payment
of principal of,  premium, if  any, and interest  on Bearer  Securities will  be
payable,  subject to any applicable laws and regulations, at the offices of such
Paying Agents outside the United States  as the Company may designate from  time
to  time, at the  option of the  Holder, by check  or by transfer  to an account
maintained by the payee  with a bank located  outside the United States.  Unless
otherwise  indicated in an applicable Prospectus Supplement, payment of interest
on Bearer Securities  on any  Interest Payment Date  will be  made only  against
surrender  to the Paying Agent of such  coupon relating to such Interest Payment
Date. (Section 10.1) No payment with respect to any Bearer Security will be made
at any office or agency of the Company  in the United States or by check  mailed
to any address in the United States or by transfer to an account maintained with
a bank located in the United States.
 
                                       7
<PAGE>
Notwithstanding  the foregoing, payments  of principal of,  and premium, if any,
and interest on Bearer Securities denominated  and payable in U.S. dollars  will
be made at the office of the Company's Paying Agent in the Borough of Manhattan,
The  City of New  York, if (but only  if) payment of the  full amount thereof in
U.S. dollars at all offices or agencies outside the Untied States is illegal  or
effectively  precluded  by  exchange  controls  or  other  similar restrictions.
(Section 10.2)
 
    Unless otherwise indicated in  an applicable Prospectus Supplement,  payment
of  principal of, premium, if any, and interest on Registered Securities will be
made at the  office of such  Paying Agent or  Paying Agents as  the Company  may
designate from time to time, except that at the option of the Company payment of
any  interest may be made by check mailed  to the address of the person entitled
thereto as such address shall appear in the Security Register. Unless  otherwise
indicated  in an applicable Prospectus Supplement,  payment of any instalment of
interest on Registered Securities will be made to the Person in whose name  such
Registered Security is registered at the close of business on the Regular Record
Date for such interest. (Section 3.7)
 
    Unless  otherwise  indicated  in an  applicable  Prospectus  Supplement, the
Corporate Trust Office of the Trustee in The City of New York will be designated
as a Paying Agent for the Company  for payments with respect to Debt  Securities
which are issuable solely as Registered Securities and the Company will maintain
a  Paying Agent outside of  the United States for  payments with respect to Debt
Securities (subject to  the limitations described  above in the  case of  Bearer
Securities) which are issuable solely as Bearer Securities or as both Registered
Securities  and Bearer Securities.  Any Paying Agents  outside the United States
and any other  Paying Agent  in the United  States initially  designated by  the
Company  for  the Debt  Securities  will be  named  in an  applicable Prospectus
Supplement. The Company may  at any time designate  additional Paying Agents  or
rescind  the designation of any  Paying Agent or approve  a change in the office
through which any Paying Agent acts, except that, if Debt Securities of a series
are issuable solely as  Registered Securities, the Company  will be required  to
maintain  a Paying Agent in  each Place of Payment for  such series and, if Debt
Securities of a series  are issuable as Bearer  Securities, the Company will  be
required to maintain (i) a Paying Agent in the Borough of Manhattan, The City of
New  York for payments with  respect to any Registered  Securities of the series
(and for  payments  with respect  to  Bearer Securities  of  the series  in  the
circumstances  described above, but not otherwise), and (ii) a Paying Agent in a
Place of Payment located outside the United States where Debt Securities of such
series and any coupons appertaining thereto may be presented and surrendered for
payment; provided that if the Debt Securities  of such series are listed on  The
Stock  Exchange  of  the United  Kingdom  and  the Republic  of  Ireland  or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such  stock exchange shall  so require, the  Company will maintain  a
Paying  Agent in London or Luxembourg or any other required city located outside
the United States, as the case may  be, for the Debt Securities of such  series.
(Section 10.2)
 
    Payments  of  principal  of, premium,  if  any, and  interest  on Book-Entry
Securities registered in the name of any Depository or its nominee will be  made
to the Depository or its nominee, as the case may be, as the registered owner of
the global security representing such Book-Entry Securities. The Company expects
that  the  Depository, upon  receipt  of any  payment  of principal,  premium or
interest, will  credit  immediately  participants'  accounts  with  payments  in
amounts  proportionate to their respective beneficial  interests as shown on the
records of such Depository or its nominee. Neither the Company, the Trustee, any
Paying Agent nor the Securities Registrar for such Debt Securities will have any
responsibility or  liability for  any aspects  of the  records relating  to,  or
payments  made  on  account  of,  such  beneficial  ownership  interests  in the
Book-Entry Securities or for maintaining,  supervising or reviewing any  records
relating to such beneficial ownership interests.
 
    All  moneys  paid  by the  Company  to a  Paying  Agent for  the  payment of
principal of, premium, if any, or  interest on any Debt Securities which  remain
unclaimed  at the  end of  two years after  such principal,  premium or interest
shall have become due and payable will  be repaid to the Company and the  Holder
of such Debt Security or any coupon will thereafter look only to the Company for
payment thereof. (Section 10.3)

GLOBAL AND BOOK-ENTRY DEBT SECURITIES
 
    If  so specified in an applicable  Prospectus Supplement, the portion of the
Debt Securities  of  a series  which  are  issuable as  Bearer  Securities  will
initially  be  represented by  one or  more temporary  or permanent  global Debt
Securities, without interest coupons, to  be deposited with a common  depositary
in  London for the Euro-clear System ("Euro-clear") and CEDEL S.A. ("CEDEL") for
credit to the designated accounts.  Unless otherwise indicated by an  applicable
Prospectus  Supplement, on  or after 40  days following its  issuance, each such
temporary global  Debt  Security  will be  exchangeable  for  definitive  Bearer
Securities,  definitive Registered Securities or all or a portion of a permanent
global Debt Security, or any combination thereof, as specified in an  applicable
Prospectus  Supplement, only upon  written certification in the  form and to the
effect described under  "Form, Exchange, Registration  and Transfer." No  Bearer
Security  (including  a Debt  Security in  permanent  global form)  delivered in
exchange for a portion of a temporary or permanent global Debt Security shall be
mailed or otherwise delivered to any location in the United States in connection
with such exchange. (Sections 3.4 and 3.5)
 
    A Person having a  beneficial interest in a  permanent global Debt  Security
will,  except with  respect to  payment of  principal of,  premium, if  any, and
interest on such permanent global Debt Security, be treated as a Holder of  such
principal  amount of Outstanding  Debt Securities represented  by such permanent
global Debt Security as shall be specified in a written statement of the  Holder
of  such permanent global  Debt Security or,  in the case  of a permanent global
Debt Security in bearer form,  of the operator of  Euro-clear or CEDEL which  is
provided to the Trustee by such Person. (Section 2.3)
 
    If  Debt Securities to  be sold in  the United States  are designated by the
Company in a Prospectus Supplement  as Book-Entry Securities, a global  security
representing  the Book-Entry Securities will be deposited  in the name of Cede &
Co., as nominee for the Depository  representing the Debt Securities to be  sold
in  the  United States.  Upon  such deposit  of  the Book-Entry  Securities, the
Depository shall credit an account maintained or designated by an institution to
be named by the Company or any  purchaser of the Debt Securities represented  by
the  Book-Entry Securities with an aggregate  amount of Debt Securities equal to
the total number of  Debt Securities that have  been so purchased. The  specific
terms  of any depository arrangement with respect  to any portion of a series of
Debt Securities  to be  represented by  one or  more global  securities will  be
described  in the applicable Prospectus Supplement. Beneficial interests in such
Debt Securities will only  be evidenced by, and  transfers thereof will only  be
effected through, records maintained by the Depository and the institutions that
are Depository participants.
 
CERTAIN COVENANTS OF THE COMPANY
 
    The  Company  will  covenant  that  it will  not,  nor  will  it  permit any
Subsidiary (as hereinafter defined), to issue, assume or guarantee any debt  for
money  borrowed ("Debt") if such Debt is secured by a mortgage, pledge, security
interest or lien (a "mortgage" or "mortgages") upon any Forestlands or Principal
Manufacturing  Facility  (as  hereinafter  defined),  now  owned  or   hereafter
acquired,  without in any  such case effectively providing  that the Senior Debt
Securities shall be secured  equally and ratably with  (or prior to) such  Debt,
except  that the foregoing restrictions shall not  apply to (a) mortgages on any
property acquired,  constructed or  improved by  the Company  or any  Subsidiary
after April 1, 1994 which are created within 180 days after such acquisition (or
in  the  case of  property  constructed or  improved,  after the  completion and
commencement of commercial operation  of such property,  whichever is later)  to
secure  or provide  for the payment  of the  purchase price or  cost thereof, or
existing mortgages on property acquired, provided such mortgages shall not apply
to any property theretofore  owned by the Company  or any Subsidiary other  than
theretofore  unimproved real  property, (b)  mortgages on  any property acquired
from a corporation which is merged with  or into the Company or a Subsidiary  or
mortgages  outstanding at  the time  any corporation  becomes a  Subsidiary, (c)
mortgages in  favor of  the Company  or any  Subsidiary, or  (d) any  extension,
renewal  or replacement (or successive extensions, renewals or replacements), in
whole or in part, of any mortgage referred to in the foregoing clauses (a),  (b)
or   (c);  and   except  that  the   following  types   of  transactions,  among
 
                                       9
<PAGE>
others, shall not be deemed to create Debt secured by a mortgage: (x) the  sale,
mortgage  or other  transfer of timber  in connection with  an arrangement under
which the Company or a Subsidiary is  obligated to cut such timber or a  portion
thereof  in order  to provide  the transferee with  a specified  amount of money
however determined and  (y) mortgages  in favor  of governmental  bodies of  the
United  States to  secure advance,  progress or  other payments  pursuant to any
contract or statute or to secure  indebtedness incurred to finance the  purchase
price  or  cost  of  constructing  or improving  the  property  subject  to such
mortgages. (Section 10.7 of Senior Indenture)
 
    Notwithstanding the foregoing, the Company  and any Subsidiary may,  without
securing  the Senior  Debt Securities, issue,  assume or  guarantee secured Debt
(which would otherwise be subject to the foregoing restrictions) in an aggregate
amount which, together with  all other such Debt  and the Attributable Debt  (as
hereinafter  defined)  in  respect  of  Sale  and  Lease-Back  Transactions  (as
hereinafter defined) of the Company and  its Subsidiaries existing at such  time
(other  than Sale  or Lease-Back  Transactions the  proceeds of  which have been

has been owned and,  in the case of  any such Principal Manufacturing  Facility,
has  been placed in  commercial operation more  than 180 days  by the Company or
such Subsidiary and has been or is said to be sold or transferred by the Company
or such Subsidiary to such person (herein referred to as a "Sale and  Lease-Back
Transaction"),  unless  either  (a)  the Company  or  such  Subsidiary  would be
entitled to incur Debt secured by a mortgage on the property to be leased in  an
amount  equal to the Attributable Debt with  respect to such Sale and Lease-Back
Transaction without equally and ratably  securing the Senior Debt Securities  or
(b)  the Company shall, and  in any such case the  Company will covenant that it
will, apply an amount  equal to the  fair value (as determined  by its Board  of
Directors)  of the property so leased to  the retirement, within 180 days of the
effective date of any such Sale  and Lease-Back Transaction, of Debt  Securities
or  of Funded Debt of the  Company which ranks on a  parity with the Senior Debt
Securities. (Section 10.8 of Senior Indenture)

which at  the time  is  held by,  or  has been  or is  after  the date  of  this
Prospectus  transferred to, a Subsidiary  primarily for development and/or sale,

any of the  foregoing, or the  District of  Columbia, the interest  on which  is
excludable  from gross income of the  holders thereof pursuant to the provisions
of Section  103(a)  of the  Internal  Revenue Code  (or  any successor  to  such
provision)  as in effect  at the time  of issuance of  such obligations, or (ii)
which, in  the opinion  of the  Board of  Directors of  the Company,  is not  of
material  importance  to the  total business  conducted by  the Company  and its
Subsidiaries as an entirety. (Section 1.1 of Senior Indenture)

    The term  "Subsidiary"  shall mean  any  corporation  of which  at  least  a

Debt Securities  of each  series or,  in  the case  of Original  Issue  Discount
Securities,  such  amount to  be  determined as  provided  in the  definition of
"Outstanding" in the  Senior Indenture) of  the obligation of  a lessee for  net

Indenture)
 
SUBORDINATION OF SUBORDINATED DEBT SECURITIES
 
    Unless otherwise  indicated  in  the Prospectus  Supplement,  the  following
provisions will apply to the Subordinated Debt Securities.
 
    The  Subordinated  Debt Securities  will,  to the  extent  set forth  in the
Subordinated Indenture, be subordinate in right of payment to the prior  payment
in  full of all Senior Indebtedness. Upon  any payment or distribution of assets
to creditors  upon any  liquidation,  dissolution, winding  up,  reorganization,
assignment   for  the  benefit  of  creditors,  marshalling  of  assets  or  any
bankruptcy, insolvency, debt restructuring or similar proceedings in  connection
with  any insolvency  or bankruptcy  proceeding of  the Company,  the Holders of
Senior Indebtedness  will  first be  entitled  to  receive payment  in  full  of
principal  of,  and  premium, if  any,  and  interest, if  any,  on  such Senior
Indebtedness before  the Holders  of the  Subordinated Debt  Securities will  be
entitled  to receive or retain  any payment in respect  of the principal of, and
premium, if  any, or  interest, if  any, on  the Subordinated  Debt  Securities.
(Section 16.2 of Subordinated Indenture)
 
    By  reason of such subordination, in the event of liquidation or insolvency,
creditors of  the Company  may recover  less, ratably,  than Holders  of  Senior
Indebtedness and may recover more, ratably, than the Holders of the Subordinated
Debt Securities.
 
    In  the event of the  acceleration of the maturity  of any Subordinated Debt
Securities, the Holders of  all Senior Indebtedness outstanding  at the time  of
such  acceleration will  first be  entitled to  receive payment  in full  of all
amounts due thereon before the Holders of the Subordinated Debt Securities  will
be entitled to receive any payment upon the principal of (or premium, if any) or
interest,  if  any,  on  the  Subordinated  Debt  Securities.  (Section  16.3 of
Subordinated Indenture)
 
    No payments on  account of principal,  or premium, if  any, or interest,  if
any,  in respect of the Subordinated Debt  Securities may be made if there shall
have occurred and be continuing a default in any payment with respect to  Senior
Indebtedness,  or an  event of default  with respect to  any Senior Indebtedness
resulting in  the acceleration  of  the maturity  thereof,  or if  any  judicial
proceeding  shall be pending with respect to  any such default. (Section 16.4 of
Subordinated Indenture)  For  purposes  of  the  subordination  provisions,  the
payment, issuance and delivery of cash, property or securities (other than stock
and  certain  subordinated  securities  of the  Company)  upon  conversion  of a
Subordinated Debt Security will  be deemed to constitute  payment on account  of
the principal of such Subordinated Debt Security.
 
                                       11
<PAGE>
    The  Subordinated Indenture  does not  limit or  prohibit the  incurrence of
additional Senior Indebtedness, which may include indebtedness that is senior to
the Subordinated Debt Securities,  but subordinate to  other obligations of  the
Company.  The Senior  Debt Securities  constitute Senior  Indebtedness under the
Subordinated Indenture.
 
    "Senior  Indebtedness"  is  defined  to  include  all  amounts  due  on  and
obligations  in connection with any of the following, whether outstanding at the
date of  execution  of the  Subordinated  Indenture or  thereafter  incurred  or
created:  (a)  indebtedness, obligations  and  other liabilities  (contingent or
otherwise) of the Company for money borrowed, or evidenced by bonds, debentures,
notes  or  similar   instruments;  (b)  reimbursement   obligations  and   other
liabilities  (contingent or otherwise) of the Company with respect to letters of
credit, bankers'  acceptances issued  for the  account of  the Company  or  with
respect  to interest rate protection agreements or currency exchange or purchase
agreements; (c) obligations and liabilities (contingent or otherwise) in respect
of leases by the Company as lessee which, in conformity with generally  accepted
accounting principles, are accounted for as capitalized lease obligations on the
balance  sheet of the Company; (d) all  direct or indirect guarantees or similar
agreements  in  respect  of,  and  obligations  or  liabilities  (contingent  or
otherwise)  to purchase or  otherwise acquire or otherwise  to assure a creditor
against loss  of  the  Company  in  respect  of,  indebtedness,  obligations  or
liabilities  of another  Person described  in clauses  (a) through  (c); (e) any
indebtedness described  in clauses  (a)  through (d)  secured by  any  mortgage,
pledge, lien or other encumbrance existing on property which is owned or held by
the  Company, regardless of whether the  indebtedness secured thereby shall have
been assumed by the Company; and (f) any and all deferrals, renewals, extensions
and  refundings  of,  or  amendments,  modifications  or  supplements  to,   any
indebtedness,  obligation  or liability  of the  kind  described in  clauses (a)
through (e); unless in  any case in the  instrument creating or evidencing  such
indebtedness,  obligation, liability,  guaranty, assumption,  deferral, renewal,
extension or  refunding,  it is  provided  that such  indebtedness,  obligation,
liability,  guaranty,  assumption,  deferral,  renewal,  extension  or refunding
involved is not senior in right  of payment to the Subordinated Debt  Securities
or  that such indebtedness is PARI PASSU with or junior to the Subordinated Debt
Securities. (Section 1.1 of Subordinated Indenture)
 
    The Prospectus  Supplement  may further  describe  the provisions,  if  any,
applicable  to  the  subordination  of the  Subordinated  Debt  Securities  of a
particular series.
 
CONVERSION RIGHTS
 
    The terms on  which Debt Securities  of any series  are convertible into  or
exchangeable  for Common Stock  or other securities  of the Company  will be set
forth in the  Prospectus Supplement  relating thereto. Such  terms will  include
provisions  as to whether conversion or exchange  is mandatory, at the option of
the Holder or at the option of the Company, and may include provisions  pursuant
to which the number of shares of Common Stock or other securities of the Company
to be received by the Holders of Debt Securities would be subject to adjustment.
 
EVENTS OF DEFAULT
 
    Any  one of the following  events will constitute an  Event of Default under
the applicable Indenture  with respect  to Debt  Securities of  any series:  (a)
failure  to  pay any  interest on  any Debt  Security of  that series  when due,
continued for 30 days (in the case of the Subordinated Indenture, whether or not
such payment is prohibited by the subordination provisions); (b) failure to  pay
principal  of or premium, if  any, on any Debt Security  of that series when due
(in the  case of  the Subordinated  Indenture, whether  or not  such payment  is
prohibited  by the subordination provisions); (c) failure to deposit any sinking
fund payment, when due, in respect of  any Debt Security of that series (in  the
case of the Subordinated Indenture, whether or not such deposit is prohibited by
the  subordination provisions); (d) failure to perform any other covenant of the
Company in the applicable Indenture or such Debt Security (other than a covenant
included in the applicable Indenture solely for the benefit of a series of  Debt
Securities  other than that series), continued  for 60 days after written notice
has
 
                                       12
<PAGE>
been given  as provided  in  the applicable  Indenture;  (e) certain  events  in
bankruptcy,  insolvency  or reorganization  involving the  Company; and  (f) any
other Event of  Default provided  with respect to  the Debt  Securities of  that
series. (Section 5.1)
 
    If  an Event of Default with respect to the Debt Securities of any series at
the time Outstanding occurs and is continuing, either the Trustee or the Holders
of at least 25% in aggregate principal amount of the Outstanding Debt Securities
of that series by notice as provided in the applicable Indenture may declare the
principal amount of the Debt Securities of  that series (or, in the case of  any
Debt  Security  that is  an Original  Issue Discount  Security or  the principal
amount of which is not then  determinable, such portion of the principal  amount
of such Debt Security, or such other amount in lieu of such principal amount, as
may  be specified  in the  terms of such  Debt Security)  to be  due and payable
immediately. At any  time after a  declaration of acceleration  with respect  to
Debt Securities of any series has been made, but before a judgment or decree for
payment  of money has been obtained by the Trustee, the Holders of a majority in
aggregate principal amount  of the  Outstanding Debt Securities  of that  series
may,  under certain circumstances, rescind and annul such acceleration. (Section
5.2)
 
    The Indentures will provide that, subject to the duty of the Trustee  during
default  to act with the required standard of care, the Trustee will be under no
obligation to  exercise  any  of  its rights  or  powers  under  the  applicable
Indenture at the request or direction of any of the Holders, unless such Holders
shall  have offered  to the  Trustee reasonable  indemnity. (Sections  6.1, 6.3)
Subject to such provisions for the  indemnification of the Trustee, the  Holders
of  a majority in aggregate principal  amount of the Outstanding Debt Securities
of any  series will  have the  right to  direct the  time, method  and place  of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Debt Securities
of that series. (Section 5.12)
 
    The Company will be required to furnish to the applicable Trustee annually a
statement  as  to  the  performance  of certain  of  its  obligations  under the
applicable Indenture and as to any default in such performance. (Section 10.9)
 
                                       13
<PAGE>
DEFEASANCE
 
    If  so specified with  respect to any particular  series of Debt Securities,
the Company may discharge its indebtedness and its obligations or certain of its
obligations under  the  applicable Indenture  with  respect to  such  series  by
depositing  funds or  obligations issued or  guaranteed by the  United States of
America with the applicable Trustee.
 
    DEFEASANCE AND DISCHARGE
 
    The Indentures will provide that, if  so specified with respect to the  Debt
Securities  of  any series,  the Company  will  be discharged  from any  and all
obligations in respect of the Debt Securities of such series (including, in  the
case  of Subordinated  Debt Securities,  the subordination  provisions described
under "Subordination  of Subordinated  Debt Securities"  herein and  except  for
certain  obligations relating to temporary Debt  Securities and exchange of Debt
Securities, registration  of transfer  or exchange  of Debt  Securities of  such
series, replacement of stolen, lost or mutilated Debt Securities of such series,
maintenance  of paying agencies, to hold monies for payment in trust and payment
of additional  amounts,  if  any,  required  in  consequence  of  United  States
withholding  taxes imposed  on payments to  non-United States  persons) upon the
deposit with the applicable Trustee, in  trust, of money and/or U.S.  Government
Obligations  which  through the  payment of  interest  and principal  in respect
thereof in  accordance  with  their  terms  will  provide  money  in  an  amount
sufficient  to pay the  principal of (and  premium, if any),  each instalment of
interest on,  and any  sinking fund  payments on,  the Debt  Securities of  such
series  on the Stated Maturity of such  payments in accordance with the terms of
the applicable Indenture and  the Debt Securities of  such series. Such a  trust
may only be established if, among other things, (a) the Company has delivered to
the  applicable Trustee an Opinion of Counsel to the effect that (i) the Company
has received from, or there has been published by, the Internal Revenue  Service
a  ruling, or (ii) since  the date of the applicable  Indenture there has been a
change in applicable federal income tax law, in either case to the effect  that,
and  based thereon such  Opinion of Counsel  shall confirm that,  the Holders of
Debt Securities  of such  series will  not recognize  income, gain  or loss  for
federal  income  tax  purposes  as  a result  of  such  deposit,  defeasance and
discharge, and will be subject to federal income tax on the same amounts and  in
the  same manner  and at  the same  times as  would have  been the  case if such
deposit, defeasance and discharge had not  occurred; (b) the Debt Securities  of
such series, if then listed on any domestic or foreign securities exchange, will
not  be delisted as a result of  such deposit, defeasance and discharge; and (c)
in the case of the Subordinated Debt  Securities, (x) no default in the  payment
of  principal of, or premium, if any, or any interest on any Senior Indebtedness
beyond any applicable grace period shall have occurred and be continuing, or (y)
no other default with respect to any Senior Indebtedness shall have occurred and
be continuing  and  shall have  resulted  in  the acceleration  of  such  Senior
Indebtedness. (Section 4.3) In the event of any such defeasance and discharge of
Debt  Securities of such series, Holders of Debt Securities of such series would
be able to  look only to  such trust fund  for payment of  principal of and  any
premium and any interest on their Debt Securities until Maturity.
 
    DEFEASANCE OF CERTAIN OBLIGATIONS
 
    The  Senior Indenture will provide that, if so specified with respect to the
Senior Debt Securities of any  series, the Company may  omit to comply with  the
restrictive  covenants described under "Certain  Covenants of the Company" above
and any other  covenants applicable  to such  Senior Debt  Securities which  are
subject  to covenant defeasance and  any such omission shall  not be an Event of
Default with respect  to the Debt  Securities of such  series, upon the  deposit
with  the Trustee, in trust, of money  and/ or U.S. Government Obligations which
through the payment of interest and  principal in respect thereof in  accordance
with their terms will provide money in an amount sufficient to pay the principal
of  (and premium, if any),  each instalment of interest  on and any sinking fund
payments on the Senior Debt Securities of such series on the Stated Maturity  of
such  payments in  accordance with  the terms  of the  Senior Indenture  and the
Senior Debt Securities of such series. The obligations of the Company under  the
Senior  Indenture and the Senior Debt Securities  of such series other than with
respect to such covenant shall remain in full force and effect. Such a trust may
be established only  if, among other  things, the Company  has delivered to  the
Trustee    an   Opinion    of   Counsel   to    the   effect    that   (i)   the
 
                                       14
<PAGE>
Holders of the Senior Debt Securities of such series will not recognize  income,
gain  or loss for  federal income tax purposes  as a result  of such deposit and
defeasance of certain obligations and will  be subject to federal income tax  on
the same amounts and in the same manner and at the same times as would have been
the  case if such  deposit and defeasance  has not occurred  and (ii) the Senior
Debt Securities  of such  series, if  then  listed on  any domestic  or  foreign
securities  exchange,  will not  be delisted  as  a result  of such  deposit and
defeasance. (Section 10.11 of Senior Indenture)
 
    In the event the  Company exercises its option  to omit compliance with  the
covenants  described under "Certain Covenants of the Company" above with respect
to the Senior Debt Securities  of any series as  described above and the  Senior
Debt  Securities of  such series  are declared  due and  payable because  of the
occurrence of any Event of Default, then the amount of money and U.S. Government
Obligations on deposit with the Trustee will be sufficient to pay amounts due on
the Senior Debt Securities of such series  at the time of their Stated  Maturity
but  may not be sufficient  to pay amounts due on  the Senior Debt Securities of
such series at  the time of  the acceleration resulting  from such Default.  The
Company  shall in any event  remain liable for such  payments as provided in the
Senior Indenture.
 
MEETINGS, MODIFICATION AND WAIVER
 
    Modifications and amendments of  the Indentures may be  made by the  Company
and  the Trustee  under the  applicable Indenture only  with the  consent of the
Holders of not less than 66  2/3% aggregate principal amount of the  Outstanding
Debt  Securities  issued under  the applicable  Indenture  and affected  by such
modification  or  amendment  unless  a  greater  percentage  of  such  aggregate
principal amount is specified in the applicable Prospectus Supplement; provided,
however, that no such modification or amendment may, without the consent of each
Holder of such Outstanding Debt Security affected thereby, (a) change the Stated
Maturity  of the principal of, or any instalment of principal of or interest on,
any such Debt Security, (b)  reduce the principal amount  of, or any premium  or
interest on, any such Debt Security, (c) change any obligation of the Company to
pay  additional amounts, (d) reduce the amount of principal of an Original Issue

suit  for the  enforcement of any  payment on or  with respect to  any such Debt
Security, (g)  adversely change  the  right to  convert or  exchange,  including
decreasing  the conversion rate or increasing the conversion price of, such Debt
Security (if applicable), (h) in the case of the Subordinated Indenture,  modify
the  subordination  provisions  in  a  manner  adverse  to  the  Holders  of the
Subordinated Debt Securities, (i) reduce  the percentage in principal amount  of
Outstanding  Debt  Securities of  any series,  the consent  of whose  Holders is

of  certain defaults,  (j) reduce the  requirements contained  in the applicable
Indenture for quorum  or voting, (k)  change any obligations  of the Company  to
maintain  an office or agency in the places and for the purposes required by the
Indentures, or (l) modify any of the above provisions. (Section 9.2)
 
    The Holders  of  at least  66  2/3% in  aggregate  principal amount  of  the
Outstanding  Debt Securities of each series may, on behalf of the Holders of all
the Debt Securities of that series, waive, insofar as that series is  concerned,
compliance  by the Company with certain restrictive provisions of the applicable
Indenture and, if applicable, such Debt Securities, unless a greater  percentage
of  such aggregate  principal amount is  specified in  the applicable Prospectus
Supplement. (Section 10.10) The Holders of not less than a majority in aggregate
principal amount  of the  Outstanding Debt  Securities of  each series  may,  on
behalf  of  all  Holders of  Debt  Securities  of that  series  and  any coupons
pertaining thereto,  waive  any past  default  under the  applicable  Indenture,
except  a default (a) in the payment of principal of, or premium, if any, or any
interest on any Debt Security of such  series, and (b) in respect of a  covenant
or  provision  of  the  applicable  Indenture  and,  if  applicable,  such  Debt
Securities which cannot be modified or amended without the consent of the Holder
of each Outstanding Debt Security of such series affected. (Section 5.13)
 
                                       15
<PAGE>
    The applicable  Indenture  will  provide that  in  determining  whether  the
Holders  of the  requisite principal amount  of the  Outstanding Debt Securities
have given any  request, demand,  authorization, direction,  notice, consent  or
waiver  thereunder or are present at a meeting of Holders of Debt Securities for
quorum purposes, (i) the principal amount of an Original Issue Discount Security
that shall be  deemed to be  Outstanding shall  be the amount  of the  principal
thereof  that would be due and payable as of the date of such determination upon
acceleration of the Maturity  thereof, and (ii) the  principal amount of a  Debt
Security  denominated in a foreign currency or  currency units shall be the U.S.
dollar equivalent, determined  on the  date of  original issuance  of such  Debt
Security,  of the principal amount  of such Debt Security or,  in the case of an
Original Issue Discount Security, the U.S. dollar equivalent, determined on  the
date  of original issuance  of such Debt  Security, of the  amount determined as
provided in (i) above. (Section 1.1)
 
    The applicable Indenture will contain  provisions for convening meetings  of
the Holders of Debt Securities of a series if Debt Securities of that series are
issuable  as Bearer Securities.  (Section 13.1) A  meeting may be  called at any
time by the Trustee, and also, upon request, by the Company or the Holders of at
least 10% in principal amount of the Outstanding Debt Securities of such series,
in any such case upon notice given in accordance with "Notices" below.  (Section
13.2)  Except  for  any  consent which  must  be  given by  the  Holder  of each
Outstanding Debt Security affected thereby,  as described above, any  resolution
presented  at a meeting or adjourned meeting at which a quorum is present may be
adopted by the affirmative vote of the Holders of a majority in principal amount
of the  Outstanding Debt  Securities of  that series;  provided, however,  that,

Debt Security affected thereby, as described above, any resolution with  respect
to  any consent or  waiver which may  be given by  the Holders of  not less than
66 2/3% in principal amount of the  Outstanding Debt Securities of a series  may

REDEMPTION AT THE OPTION OF HOLDERS UPON CHANGE IN CONTROL
 
    In  the  event of  any Change  in  Control (as  hereinafter defined)  of the
Company, prior to maturity of the Debt Securities, that has not been approved by
the  Continuing  Directors  (as  hereinafter  defined)  of  the  Company,   Debt
Securities  may be submitted for  redemption, on and after  the Exchange Date in
the case of Debt Securities  of any series issuable  as Bearer Securities or  at
any time in the case of all other Debt Securities, at the option of the Holders,
unless,  prior to the expiration  of ten days following  such Change in Control,
the Company, if  permitted to do  so by the  terms of the  Debt Securities of  a
series,  shall  have  called all  of  the  Debt Securities  of  such  series for
redemption. Bearer Securities may  be so redeemed only  in whole and  Registered
Securities  in whole or in part in  increments of $1,000. Any Debt Securities to
be so  submitted must  be  submitted during  a  period (the  "Exercise  Period")
commencing  on the date  of the Company's  notice described below  to Holders of
such Change in Control and expiring on  the 20th business day after such  notice
is given.
 
    Debt  Securities submitted for  redemption will be  redeemed on a Redemption
Date that will be  the 15th day  after expiration of the  Exercise Period, at  a
redemption  price of  100% of  the principal amount  of the  Debt Security, plus
accrued interest to the Redemption Date.  Exercise of this redemption option  by
the Holder of a Debt Security will be irrevocable.
 
    On  or  before the  tenth  day after  a Change  in  Control, the  Company is
obligated, unless the Continuing Directors have approved such Change in  Control
prior  to such  date, to  give notice  to Holders  as set  forth under "Notices"
below, and written notice to the  Trustee, regarding the Change in Control,  the
date  of expiration of the Exercise  Period, the applicable Redemption Date, the
redemption price and the procedure which the Holder must follow to exercise this
option. To  exercise this  option, the  Holder  must deliver  on or  before  the
expiration  of the Exercise Period to one of the Paying Agents referred to below
written notice of the Holder's exercise  of such option, together with the  Debt
Securities  with respect to  which the option is  being exercised, duly endorsed
(in the  case  of Registered  Securities)  for transfer.  Each  Bearer  Security
delivered  for redemption must be delivered  with all coupons maturing after the
Redemption Date. If the  Redemption Date falls between  any Regular Record  Date
and  the next succeeding Payment Date, Registered Securities must be accompanied
by payment  of an  amount equal  to the  interest thereon  which the  registered
Holder is to receive on such Interest Payment Date.
 
    As used herein, a "Change in Control" of the Company shall be deemed to have
occurred  at such time or times as (a) the Company determines that any person or
related group of persons is the beneficial owner, directly or indirectly, of 20%
or more of the  outstanding Common Stock or  (b) individuals who constitute  the
Continuing  Directors cease for any reason to  constitute at least a majority of
the Company's  directors. "Continuing  Director"  means any  director who  is  a
director  on the date hereof  and any director who is  nominated or elected by a
majority of Continuing Directors who are then directors.
 
    The Company could, in the future, enter into certain transactions, including
certain recapitalizations or leveraged transactions  of the Company, that  would
not  constitute a Change in Control or  would constitute a Change of Control but
would not trigger the Change of Control purchase feature of the Debt  Securities
if  approved by the  Continuing Directors and  would increase the  amount of the
Company's indebtedness outstanding at such  time. However, the Senior  Indenture
contains  covenants  of the  Company limiting  its ability  to mortgage  or sell
Principal Manufacturing Facilities or Forestlands.  If a Change in Control  were
to occur, there can be no assurance that the Company would have sufficient funds
to  pay the Change in Control purchase price for all Debt Securities tendered by
the Holders  thereof.  In  addition,  the Company's  ability  to  purchase  Debt
Securities  with cash may be limited by the terms of its then-existing borrowing
agreements. A default  by the Company  on its  obligation to pay  the Change  in
Control  purchase price or a breach of its  covenant would result in an Event of
Default and could result in acceleration  of the maturity of other  indebtedness
of the Company at the time outstanding pursuant to cross-default provisions. The
Company  will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other
tender offer rules under the Exchange Act
 
                                       17
<PAGE>
which may  then be  applicable  and will  file a  Schedule  13E-4 or  any  other
schedule required thereunder and will otherwise comply with all federal or state
securities  laws, as  required, in  connection with  any of  the Debt Securities
providing for redemption at the option of Holders.
 
NOTICES
 
    Except as otherwise provided in the applicable Indenture, notices to Holders
of Bearer Securities  will be given  by publication  at least twice  in a  daily
newspaper  in The City of  New York and in  such other city or  cities as may be
specified in such Debt Securities.  Notices to Holders of Registered  Securities
will  be given  by mail to  the address  of such Holders  as they  appear in the
Security Register. (Sections 1.1, 1.6)
 
TITLE
 
    Title  to  any  temporary  global  Debt  Security,  any  Bearer   Securities
(including   Bearer  Securities  in  permanent  global  form)  and  any  coupons
appertaining thereto will  pass by delivery.  The Company, the  Trustee and  any
agent  of the Company or the Trustee may treat the bearer of any Bearer Security
and the bearer of any coupon and the registered owner of any Registered Security
as the absolute owner thereof (whether or not such Debt Security or coupon shall
be overdue and notwithstanding  any notice to the  contrary) for the purpose  of
making payment and for all other purposes. (Section 3.8)
 
REPLACEMENT OF DEBT SECURITIES AND COUPONS
 
    Any  mutilated  Debt Security  or a  Debt Security  with a  mutilated coupon
appertaining thereto  will be  replaced by  the Company  at the  expense of  the
Holder  upon surrender of such Debt Security  to the Trustee. Debt Securities or
coupons that became destroyed, stolen or lost will be replaced by the Company at
the expense of the Holder upon delivery of the Trustee of the Debt Security  and
coupons  or evidence of  the destruction, loss or  theft thereof satisfactory to
the Company and the Trustee; in the case of any coupon which becomes  destroyed,
stolen  or lost, such coupon will be replaced by issuance of a new Debt Security
in exchange for the Debt Security to  which such coupon appertains. In the  case
of   a  destroyed,  lost  or  stolen  Debt  Security  or  coupon,  an  indemnity
satisfactory to the Trustee and  the Company may be  required at the expense  of
the  Holder of such Debt  Security or coupon before  a replacement Debt Security
will be issued. (Section 3.6)
 
GOVERNING LAW
 
    The Indentures, the Debt Securities and the coupons will be governed by, and
construed in accordance with, the laws of  the State of New York without  regard
to principles of conflicts of laws. (Section 1.13)
 
REGARDING THE TRUSTEE
 
    The  Indentures  contain  limitations on  the  right  of the  Trustee,  as a
creditor of the  Company, to obtain  payment of  claims in certain  cases or  to
realize on certain property received in respect of any such claim as security or
otherwise. In addition, the Trustee may be deemed to have a conflicting interest
and  may be required to resign as Trustee if  at the time of a default under one
of the Indentures it  is a creditor  of the Company.  The Chase Manhattan  Bank,
N.A.  also acts as trustee under various  indentures and the Company and certain
subsidiaries from  time to  time  maintain deposit  accounts and  conduct  their
banking  transactions with The Chase Manhattan Bank, N.A. in the ordinary course
of their business.
 
MEDIUM-TERM NOTES
 
    The Company  may  offer from  time  to  time up  to  $400,000,000  aggregate
principal  amount  of  its  medium-term  notes  (the  "Medium-Term  Notes"). The
particular terms and provisions  of the Medium-Term Notes  will be described  in
the  Prospectus Supplement relating  to such Medium-Term  Notes. The Medium-Term
Notes will be issued as a series  of Senior Debt Securities under an  Indenture,
dated  as of May 22, 1992, as  supplemented by the First Supplemental Indenture,
dated as  of June  26,  1992 (the  "Medium-Term  Note Indenture"),  between  the
Company  and The Bank of  New York, as trustee. The  terms and provisions of the
Medium-Term Note Indenture are substantially
 
                                       18
<PAGE>
similar to those to be contained  in the Senior Note Indenture. The  Medium-Term
Note  Indenture is incorporated  by reference as an  exhibit to the Registration
Statement of which this Prospectus is a part.
 
                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized  capital stock  of the  Company consists  of (i)  400,000,000
shares  of common stock,  $1.00 par value  per share (the  "Common Stock"), (ii)
400,000 shares of  cumulative $4  preferred stock,  without par  value (the  "$4
Preferred  Stock"), and (iii) 8,750,000 shares  of serial preferred stock, $1.00
par value per share (the "Preferred Stock").
 
    At March 31, 1996, there were  outstanding (a) 298,347,521 shares of  Common
Stock  (as well as the  same number of Common  Share Purchase Rights to purchase
Common Stock pursuant to  the Rights Agreement), (b)  employee stock options  to
purchase  an aggregate of  approximately 10,600,000 shares  of Common Stock, (c)
32,034 shares of $4 Preferred Stock and (d) no shares of any series of Preferred
Stock. In addition, approximately 8,333,333 shares of Common Stock were reserved
for  issuance  upon  conversion   of  the  Company's  convertible   subordinated
debentures.
 
                         DESCRIPTION OF PREFERRED STOCK
 
    The following summary contains a description of certain general terms of the
Company's Preferred Stock to which any Prospectus Supplement may relate. Certain
terms of any series of Preferred Stock offered by any Prospectus Supplement will
be  described in the Prospectus Supplement  relating thereto. If so indicated in
the Prospectus Supplement, the terms of any series may differ from the terms set
forth below. The description  of certain provisions  of the Company's  Preferred
Stock  does not purport  to be complete and  is subject to  and qualified in its
entirety by reference to the provisions of the Company's Restated Certificate of
Incorporation (the "Restated Certificate of Incorporation"), and the Certificate
of Designation (the  "Certificate of Designation")  relating to each  particular
series  of Preferred Stock which will be  filed or incorporated by reference, as
the case may  be, as  an exhibit  to the  Registration Statement  of which  this
Prospectus  is a part at or prior to  the time of the issuance of such Preferred
Stock.
 
GENERAL
 
    Under the  Company's Restated  Certificate of  Incorporation, the  Board  of
Directors  of the Company is authorized,  without further stockholder action, to
provide for  the issuance  of up  to 8,750,000  shares of  Preferred Stock.  The
Preferred  Stock may be issued in one  or more series, with such designations of
titles; dividend rates; any redemption provisions; special or relative rights in
the event  of  liquidation,  dissolution,  distribution or  winding  up  of  the
Company;  any  sinking fund  provisions; any  conversion provisions;  any voting
rights  thereof;  and  any   other  preferences,  privileges,  powers,   rights,
qualifications,  limitations and restrictions, as shall be set forth as and when
established by the Board of Directors of  the Company. The shares of any  series
of  Preferred  Stock will  be, when  issued, fully  paid and  non-assessable and
holders thereof will have no preemptive rights in connection therewith.
 
    So  long  as  any  shares  of  $4  Preferred  Stock  are  outstanding,   the
preferences,  privileges and voting  powers, if any, of  the shares of Preferred
Stock of any series,  and the restrictions or  qualifications thereof, shall  be
subject  to the preferences, privileges and voting powers, if any, of the shares
of $4 Preferred Stock and the restrictions and qualifications thereof.
 
RANK
 
    Any series of Preferred Stock will,  with respect to rights on  liquidation,
winding  up and dissolution, rank (i) senior  to all classes of Common Stock and
to all equity securities issued by the Company, the terms of which  specifically
provide that such equity securities will rank junior to such series of Preferred
Stock  (the "Junior Liquidation  Securities"); (ii) on a  parity with all equity
securities issued by the Company, the  terms of which specifically provide  that
such equity securities will rank on a
 
                                       19
<PAGE>
parity  with such series  of Preferred Stock  ("Parity Liquidation Securities");
and (iii) junior to all  equity securities issued by  the Company, the terms  of
which  specifically provide that such equity securities will rank senior to such
series of  Preferred  Stock,  including  the $4  Preferred  Stock  (the  "Senior
Liquidation  Securities"). In addition, any series of Preferred Stock will, with
respect to dividend rights, rank (i)  senior to all equity securities issued  by
the Company, the terms of which specifically provide that such equity securities
will  rank junior to such series of  Preferred Stock and, to the extent provided
in the applicable Certificate of Designation, to Common Stock, (ii) on a  parity
with   all  equity  securities  issued  by  the  Company,  the  terms  of  which
specifically provide that such equity securities will rank on a parity with such
series of  Preferred  Stock  and,  to the  extent  provided  in  the  applicable
Certificate  of Designation, to Common  Stock ("Parity Dividend Securities") and
(iii) junior to all equity securities issued by the Company, the terms of  which
specifically provide that such equity securities will rank senior to such series
of Preferred Stock, including the $4 Preferred Stock. As used in any Certificate
of Designation for these purposes, the term "equity securities" will not include
debt securities convertible into or exchangeable for equity securities.
 
DIVIDENDS
 
    Holders of each series of Preferred Stock will be entitled to receive, when,
as and if declared by the Board of Directors of the Company out of funds legally
available  therefor, cash dividends at  such rates and on  such dates as are set
forth in the Prospectus Supplement relating  to such series of Preferred  Stock.
Dividends will be payable to holders of record of Preferred Stock as they appear
on  the books of the  Company (or, if applicable,  the records of the Depositary
referred to below under "Description of Depositary Shares") on such record dates
as shall  be  fixed by  the  Board of  Directors.  Dividends on  any  series  of
Preferred Stock may be cumulative or non-cumulative.
 
    No full dividends may be declared or paid on funds set apart for the payment
of  dividends on any series of Preferred  Stock unless dividends shall have been
paid or set apart for  such payment on the  Parity Dividend Securities. If  full
dividends  are not so paid, such series of Preferred Stock shall share dividends
pro rata with the Parity Dividend Securities.
 
CONVERSION AND EXCHANGE
 
    The Prospectus Supplement for any series  of Preferred Stock will state  the
terms,  if any, on  which shares of  that series are  convertible into shares of
another series of Preferred  Stock or Common Stock  or exchangeable for  another
series  of Preferred Stock, Common Stock or  Debt Securities of the Company. The
Common Stock of  the Company  is described  below under  "Description of  Common
Stock."
 
REDEMPTION
 
    A  series of Preferred Stock  may be redeemable at any  time, in whole or in
part, at the option of the Company or  the holder thereof and may be subject  to
mandatory  redemption pursuant to a sinking fund  or otherwise upon terms and at
the redemption prices set  forth in the Prospectus  Supplement relating to  such
series.
 
    In the event of partial redemptions of Preferred Stock, whether by mandatory
or  optional redemption, the shares to be  redeemed will be determined by lot or
pro rata, as may be determined by the  Board of Directors of the Company, or  by
any other method determined to be equitable by the Board of Directors.
 
    On  and after a redemption date, unless  the Company defaults in the payment
of the redemption price, dividends will  cease to accrue on shares of  Preferred
Stock  called  for redemption  and all  rights  of holders  of such  shares will
terminate except for the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
    Upon any voluntary or involuntary liquidation, dissolution or winding up  of
the  Company, holders of each series of Preferred Stock that ranks senior to the
Junior Liquidation Securities will be entitled  to receive out of assets of  the
Company    available    for   distribution    to   shareholders,    before   any
 
                                       20
<PAGE>
distribution is  made on  any Junior  Liquidation Securities,  including  Common
Stock,  distributions upon liquidation in the amount set forth in the Prospectus
Supplement relating to such series of  Preferred Stock, plus an amount equal  to
any  accrued  and  unpaid  dividends.  If,  upon  any  voluntary  or involuntary
liquidation, dissolution or winding up of the Company, the amounts payable  with
respect  to the Preferred Stock  of any series and  any other Parity Liquidation
Securities are not  paid in full,  the holders  of the Preferred  Stock of  such
series  and the  Parity Liquidation  Securities will  share ratably  in any such
distribution of assets  of the  Company in  proportion to  the full  liquidation
preferences  to which each is entitled. After  payment of the full amount of the
liquidation preference to which they are entitled, the holders of such series of
Preferred Stock  will  not be  entitled  to  any further  participation  in  any
distribution of assets of the Company.
 
VOTING RIGHTS
 
    Except  as indicated  below or  in the  Prospectus Supplement  relating to a
particular series  of  Preferred  Stock  or  except  as  expressly  required  by
applicable  law, the holders  of shares of  Preferred Stock will  have no voting
rights.
 
PREFERRED STOCK OUTSTANDING
 
    As of March 31, 1996, the  Company had issued and outstanding 32,034  shares
without par value of $4 Preferred Stock, which is senior to the Common Stock and
the  Preferred Stock as to the payment  of dividends and distributions of assets
on liquidation, dissolution or winding up of the Company. The $4 Preferred Stock
bears a dividend of $4.00 per share per annum from the surplus or net profits of
the Company, but only when and as declared by the Board of Directors.  Dividends
on  the $4 Preferred Stock are  cumulative. Such dividends are payable quarterly
in each year on such  dates as from time  to time may be  fixed by the Board  of
Directors. Accumulation of dividends do not bear interest.
 
    If dividends in full on all outstanding shares of the $4 Preferred Stock for
all  past quarterly dividend  periods and for the  then current quarterly period
have not been paid or  declared and set apart  for payment, no dividends  (other
than  dividends payable in stock ranking junior  to the $4 Preferred Stock) will
be declared or paid or  set apart for payment on,  nor will any distribution  be
made to, any class of stock ranking junior to the $4 Preferred Stock.
 
    Holders of the $4 Preferred Stock have no general voting rights but have the
right to vote in certain specified circumstances.
 
    If  at the time  of any annual  meeting of shareholders,  dividends have not
been paid on the shares of the  $4 Preferred Stock in an aggregate amount  equal
to  four full  quarterly dividends  (whether consecutive  or not),  then at such
annual meeting, the holders of the $4 Preferred Stock will have the sole  right,
to  the exclusion of all other classes of stock, to vote for and elect one-third
(or the nearest whole  number thereto) of  the total number  of directors to  be
elected  at  the meeting  and thereafter  at  all meetings  for the  election of
directors until  all arrearages  of dividends  accumulated on  the $4  Preferred
Stock  for all preceding dividend  periods shall have been  paid or declared and
set apart for payment.  Whenever all arrearages of  dividends have been paid  or
declared  and  set  apart for  payment,  all powers  of  the holders  of  the $4
Preferred Stock to  vote for  directors will terminate,  and the  tenure of  all
Directors elected by them will automatically end.
 
    So  long  as any  shares  of the  $4  Preferred Stock  are  outstanding, the
Company, without  first  obtaining  a  majority  vote  of  the  holders  of  the
outstanding  shares  of  the  $4  Preferred  Stock,  may  not  (i)  increase the
authorized number of $4 Preferred Stock,  (ii) authorize, create or issue  stock
of  any class  ranking, as  to the  payment of  dividends or  distributions upon
dissolution, liquidation or winding up, on a parity with the $4 Preferred Stock,
or (iii) sell, lease  or otherwise dispose  of all or  substantially all of  the
assets of the Company, otherwise than by merger or consolidation.
 
    In  addition, so long as  any shares of $4  Preferred Stock are outstanding,
the Company may not,  without first obtaining  the vote of  holders of at  least
two-thirds of the outstanding shares of $4 Preferred Stock, authorize, create or
issue stock of any class ranking, as to the payment of dividends or distribution
upon dissolution, liquidation or winding up, senior to the $4 Preferred Stock.
 
                                       21
<PAGE>
    The  Company's Restated  Certificate of  Incorporation provides  that for so
long as any  shares of  Preferred Stock are  outstanding, the  Company will  not
issue  any  shares  of  the  $4  Preferred  Stock  without  first  obtaining the
affirmative vote of the holders of at least a majority of the outstanding shares
of Preferred Stock.
 
    Upon the dissolution, liquidation or winding up of the Company, the  holders
of  the $4 Preferred Stock will be entitled  to receive out of the net assets of
the  Company  (whether  represented  by   capital  or  surplus),  (i)  if   such
dissolution, liquidation or winding up is voluntary, cash in an amount per share
of $105, and (ii) if such dissolution, liquidation or winding up is involuntary,
cash in the amount of $100 per share. In addition, such holders will be entitled
to receive, in each case, an amount equal to all dividends accrued and unpaid on
such  share up to and including the  date fixed for distribution, whether or not
earned or declared and, in either case, before any distribution of the assets to
be distributed  is  made to  the  holders of  stock  ranking junior  to  the  $4
Preferred Stock.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
    The  description  set  forth  below of  certain  provisions  of  the Deposit
Agreement (as  defined  below)  and  of the  Depositary  Shares  and  Depositary
Receipts  (as defined below) does  not purport to be  complete and is subject to
and qualified in its entirety by reference to the forms of Deposit Agreement and
Deposit Receipt relating  to the Preferred  Stock, included as  exhibits to  the
Registration Statement of which this Prospectus is a part.
 
GENERAL
 
    The  Company  may,  at  its  option, elect  to  offer  fractional  shares of
Preferred Stock, rather than full shares  of Preferred Stock. In the event  such
option is exercised, the Company will issue receipts for Depositary Shares, each
of which will represent a fraction (to be set forth in the Prospectus Supplement
relating  to a particular series of Preferred  Stock) of a share of a particular
series of Preferred Stock as described below.
 
    The shares of any series of Preferred Stock represented by Depositary Shares
will be deposited under  a Deposit Agreement  (the "Deposit Agreement")  between
the  Company and  a bank  or trust  company selected  by the  Company having its
principal office in the United States and having a combined capital and  surplus
of  at least $50,000,000 (the "Depositary"). Subject to the terms of the Deposit
Agreement, each owner of a Depositary  Share will be entitled, in proportion  to
the  applicable  fraction of  a  share of  Preferred  Stock represented  by such
Depositary Share,  to all  the rights  and preferences  of the  Preferred  Stock
represented  thereby  (including  dividend, voting,  redemption,  conversion and
liquidation rights).
 
    The Depositary  Shares  will  be evidenced  by  depositary  receipts  issued
pursuant  to  the  Deposit  Agreement  (the  "Depositary  Receipts"). Depositary
Receipts will be distributed to  those persons purchasing the fractional  shares
of Preferred Stock in accordance with the terms of the offering.
 
    Pending  the preparation  of definitive Depositary  Receipts, the Depositary
may, upon the written order of the Company or any holder of deposited  Preferred
Stock, execute and deliver temporary Depositary Receipts which are substantially
identical  to, and entitle the holders thereof  to all the rights pertaining to,
the  definitive  Depositary  Receipts.  Depositary  Receipts  will  be  prepared
thereafter without unreasonable delay, and temporary Depositary Receipts will be
exchangeable for definitive Depositary Receipts at the Company's expense.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
    The   Depositary  will   distribute  all   cash  dividends   or  other  cash
distributions received in respect of the deposited Preferred Stock to the record
holders of Depositary Shares relating to  such Preferred Stock in proportion  to
the numbers of such Depositary Shares owned by such holders.
 
                                       22
<PAGE>
    In  the event  of a  distribution other  than in  cash, the  Depositary will
distribute property received by  it to the record  holders of Depositary  Shares
entitled  thereto. If the Depositary determines that  it is not feasible to make
such distribution, it may, with the approval of the Company, sell such  property
and distribute the net proceeds from such sale to such holders.
 
REDEMPTION OF STOCK
 
    If  a series of  Preferred Stock represented  by Depositary Shares  is to be
redeemed, the Depositary Shares will be  redeemed from the proceeds received  by
the  Depositary resulting  from the  redemption, in  whole or  in part,  of such
series of Preferred Stock held by the Depositary. The Depositary Shares will  be
redeemed  by  the  Depositary at  a  price  per Depositary  Share  equal  to the
applicable fraction of the redemption price per share payable in respect of  the
shares  of Preferred Stock  so redeemed. Whenever the  Company redeems shares of
Preferred Stock held  by the Depositary,  the Depositary will  redeem as of  the
same date the number of Depositary Shares representing shares of Preferred Stock
so  redeemed. If fewer  than all the  Depositary Shares are  to be redeemed, the
Depositary Shares to be redeemed  will be selected by  the Depositary by lot  or
pro  rata  or  by  any  other  equitable method  as  may  be  determined  by the
Depositary.
 
WITHDRAWAL OF STOCK
 
    Any holder  of  Depositary Shares  may,  upon surrender  of  the  Depositary
Receipts  at the  corporate trust office  of the Depositary  (unless the related
Depositary Shares  have  previously been  called  for redemption),  receive  the
number of whole shares of the related series of Preferred Stock and any money or
other  property represented by  such Depositary Receipts.  Holders of Depositary
Shares making  such withdrawals  will be  entitled to  receive whole  shares  of
Preferred  Stock on the basis set forth in the related Prospectus Supplement for
such series of Preferred  Stock, but holders of  such whole shares of  Preferred
Stock  will not thereafter be entitled to deposit such Preferred Stock under the
Deposit Agreement or to receive Depositary Receipts therefor. If the  Depositary
Shares  surrendered by the holder in  connection with such withdrawal exceed the
number of  Depositary  Shares that  represent  the  number of  whole  shares  of
Preferred  Stock to be withdrawn, the Depositary  will deliver to such holder at
the same  time  a  new  Depositary Receipt  evidencing  such  excess  number  of
Depositary Shares.
 
VOTING DEPOSITED PREFERRED STOCK
 
    Upon  receipt of notice of any meeting at which the holders of any series of
deposited Preferred Stock  are entitled to  vote, the Depositary  will mail  the
information  contained in such  notice of meeting  to the record  holders of the
Depositary Shares relating to such series of Preferred Stock. Each record holder
of such Depositary Shares on the record date (which will be the same date as the
record date for  the relevant  series of Preferred  Stock) will  be entitled  to
instruct  the Depositary as to  the exercise of the  voting rights pertaining to
the amount  of  the Preferred  Stock  represented by  such  holder's  Depositary
Shares. The Depositary will endeavor, insofar as practicable, to vote the amount
of  such  series of  Preferred Stock  represented by  such Depositary  Shares in
accordance with  such instructions,  and  the Company  will  agree to  take  all
reasonable  actions that may be  deemed necessary by the  Depositary in order to
enable the Depositary to do so.  The Depositary will abstain from voting  shares
of  the Preferred Stock to the extent  it does not receive specific instructions
from the holder of Depositary Shares representing such Preferred Stock.
 
AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT
 
    The form  of Depositary  Receipt evidencing  the Depositary  Shares and  any
provision  of the  Deposit Agreement  may at  any time  be amended  by agreement
between the Company and the Depositary. However, any amendment which  materially
and  adversely  alters  the  rights  of the  holders  of  the  Depositary Shares
representing Preferred Stock  of any series  will not be  effective unless  such
amendment  has  been approved  by  the holders  of at  least  the amount  of the
Depositary Shares then outstanding representing the minimum amount of  Preferred
Stock  of such series  necessary to approve any  amendment that would materially
and  adversely   affect   the  rights   of   the  holders   of   the   Preferred
 
                                       23
<PAGE>
Stock  of such series. Every holder of  an outstanding Depositary Receipt at the
time any such  amendment becomes effective,  or any transferee  of such  holder,
shall  be deemed, by continuing to hold such Depositary Receipt, or by reason of
the acquisition thereof, to consent and agree to such amendment and to be  bound
by the Deposit Agreement as amended thereby. The Deposit Agreement automatically
terminates  if (i) all outstanding Depositary Shares have been redeemed; or (ii)
each share of Preferred Stock has  been converted into other preferred stock  or
Common  Stock or has been exchanged for debt securities; or (iii) there has been
a final distribution in  respect of the Preferred  Stock in connection with  any
liquidation,  dissolution or winding up of the Company and such distribution has
been distributed to the holders of Depositary Shares.
 
CHARGES OF DEPOSITARY
 
    The Company will pay all transfer  and other taxes and governmental  charges
arising  solely from the  existence of the  depositary arrangements. The Company
will pay all charges of the Depositary in connection with the initial deposit of
the relevant series  of Preferred  Stock and  any redemption  of such  Preferred
Stock.  Holders of Depositary  Receipts will pay other  transfer and other taxes
and governmental charges  and such other  charges or expenses  as are  expressly
provided in the Deposit Agreement to be for their accounts.
 
RESIGNATION AND REMOVAL OF DEPOSITARY
 
    The Depositary may resign at any time by delivering to the Company notice of
its  election to do so,  and the Company may at  any time remove the Depositary,
any such  resignation  or removal  to  take effect  upon  the appointment  of  a
successor  Depositary  and its  acceptance of  such appointment.  Such successor
Depositary must be  appointed within  60 days after  delivery of  the notice  of
resignation  or removal and must be a bank or trust company having its principal
office in the  United States and  having a  combined capital and  surplus of  at
least $50,000,000.
 
MISCELLANEOUS
 
    The  Depositary will forward all reports and communications from the Company
which are  delivered to  the Depositary  and which  the Company  is required  to
furnish to the holders of the deposited Preferred Stock.
 
    Neither  the Depositary nor the Company will be liable if it is prevented or
delayed by  law  or any  circumstances  beyond  its control  in  performing  its
obligations  under the Deposit Agreement. The obligations of the Company and the
Depositary under the Deposit  Agreement will be limited  to performance in  good
faith  of their duties thereunder and they will not be obligated to prosecute or
defend any  legal proceeding  in respect  of any  Depositary Shares,  Depositary
Receipts   or  shares  of  Preferred  Stock  unless  satisfactory  indemnity  is
furnished. They may rely upon written advice of counsel or accountants, or  upon
information provided by holders of Depositary Receipts or other persons believed
to be competent and on documents believed to be genuine.
 
                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
    Subject  to  the  rights of  the  Holders  of any  shares  of  the Company's
Preferred Stock or  $4 Preferred  Stock which may  at the  time be  outstanding,
holders  of  Common Stock  are  entitled to  receive  such dividends  as  may be
declared from  time to  time by  the Board  of Directors  out of  funds  legally
available therefor.
 
    The  holders  of Common  Stock are  entitled to  one vote  per share  on all
matters submitted to a  vote of shareholders and  do not have cumulative  voting
rights. Holders of Common Stock are entitled to receive, upon any liquidation of
the  Company, all  remaining assets  available for  distribution to shareholders
after satisfaction of the Company's  liabilities and the preferential rights  of
any  preferred stock  that may then  be issued and  outstanding. The outstanding
shares of Common Stock are, and the
 
                                       24
<PAGE>
shares offered hereby  will be,  fully paid  and nonassessable.  The holders  of
Common  Stock have  no preemptive, conversion  or redemption  rights. The Common
Stock is listed on the New York Stock Exchange. The registrar and transfer agent
for the Common Stock is Chemical Bank.
 
CERTAIN PROVISIONS
 
    The Company's  Restated  Certificate of  Incorporation  contains  provisions
which:  (1) divide the Board of Directors  into three classes of as nearly equal
size as possible, with Directors in each class being elected for terms of  three
years;  (2) require  the affirmative  vote of 80%  of the  outstanding shares of
voting  stock  to  remove  any  Director  except  for  cause;  (3)  require  the
affirmative  vote of (a) 80% of the outstanding shares of voting stock and (b) a
majority of the voting stock not owned by an Interested Stockholder (an owner of
10% or more of voting power) to  approve any Business Combination (as such  term
is  defined  in the  Company's Restated  Certificate  of Incorporation)  with an
Interested Stockholder  unless  (x) the  Business  Combination shall  have  been
approved by the Board of Directors at a time when Disinterested Directors (those
directors  unaffiliated with  an Interested Stockholder  who were  either on the
Board of  Directors prior  to  the time  the  Interested Stockholder  became  an
Interested   Stockholder  or   succeeded  a  Disinterested   Director  and  were
recommended for a  nomination or  election by  a majority  of the  Disinterested
Directors)  constitute a majority of the entire Board of Directors or (y) in the
case of a Business Combination involving the payment of consideration to holders
of  capital  stock,   certain  conditions   concerning  the   adequacy  of   the
consideration  are  met;  (4)  require  the  affirmative  vote  of  80%  of  the
outstanding shares of voting  stock to amend or  repeal those provisions of  the
Company's Restated Certificate of Incorporation described in clauses (1) and (2)
above; and (5) require the affirmative vote of (x) 80% of the outstanding shares
of  voting  stock  and (y)  a  majority of  the  voting  stock not  owned  by an
Interested  Stockholder,  to  approve  any  proposal  made  by  such  Interested
Stockholder  to  amend  or repeal  those  provisions of  the  Company's Restated
Certificate of Incorporation described in clause (3) above, unless such proposal
is recommended by the Board of Directors at a time when Disinterested  Directors
constitute a majority of the entire Board of Directors.
 
    The overall effect of these provisions may be to deter or discourage hostile
takeover  attempts by  making it more  difficult for  a person who  has gained a
substantial equity interest in the Company effectively to exercise control.
 
COMMON SHARE PURCHASE RIGHTS
 
    In April 1987, the Company's Board of Directors authorized the  distribution
of  one Common Share  Purchase Right (a  "Right") for each  outstanding share of
Common Stock. Pursuant  to the  terms of  the Rights  Agreement (as  hereinafter
defined),  each share of Common Stock issued subsequent to the effective date of
such Agreement and prior to the Distribution Date (as hereinafter defined),  has
been  and will be accompanied  by one Right. Each  Right entitles the registered
holder to purchase from  the Company one  share of Common  Stock at an  exercise
price  of $77.50 (on a split-adjusted  basis), subject to adjustment as provided
below (the "Purchase Price").
 
    As distributed, the Rights trade together with the Common Stock. They may be
exercised or traded separately only after the earlier to occur of: (i) the tenth
business day  after  the commencement  of,  or  first public  disclosure  of  an
intention  to commence, a  tender or exchange  offer by a  person or group other
than the Company if, upon  consummation of the offer,  such person or group  has
acquired beneficial ownership of 20% or more of the outstanding Common Stock, or
(ii)  the tenth day after the first public announcement that an Acquiring Person
(as such term is  defined in the Rights  Agreement) has acquired the  beneficial
ownership  of 20% or more of the shares of Common Stock outstanding (the earlier
of such dates being called the "Distribution Date").
 
                                       25
<PAGE>
    The Rights will  expire on  April 29,  1997 (the  "Final Expiration  Date"),
unless  earlier redeemed  by the  Company as  provided below.  Until a  Right is
exercised, the holder thereof will have no additional rights as a shareholder of
the Company, including,  without limitation,  the right  to vote  or to  receive
dividends on shares of Common Stock subject to the Rights.
 
    In  the event that, following the Distribution Date, the Company (i) engages
in a merger or other business combination transaction with a Principal Party (as
such term is  defined in the  Rights Agreement)  in which the  shares of  Common
Stock are changed into, or exchanged for, stock or other securities of any other
person  or cash or other property, or (ii) sells or transfers 50% or more of its
assets or earnings power to a Principal Party, each holder of a Right (except as
provided below)  shall  thereafter have  the  right to  receive,  upon  exercise
thereof  at the Purchase  Price, Common Stock  of such Principal  Party having a
value of twice such Purchase  Price. In the event  that (i) an Acquiring  Person
shall  acquire beneficial ownership of 20% or more of the shares of Common Stock
outstanding, other  than pursuant  to an  offer for  all outstanding  shares  of
Common  Stock which  the Continuing  Directors (as such  term is  defined in the
Rights Agreement), determine to be in the best interests of the Company and  its
shareholders,  (ii) the Company merges with  an Acquiring Person and the Company
is the surviving corporation and all  shares of Common Stock remain  outstanding
and unchanged or (iii) an Acquiring Person engages in one or more "self-dealing"
transactions  with  the Company,  each holder  of  a Right  will be  entitled to
purchase, at  the Purchase  Price, (A)  shares of  Common Stock  of the  Company
having  a value of twice  the Purchase Price or  (B) in certain circumstances as
determined by  the  Continuing Directors,  any  combination of  cash,  property,
shares  of Common Stock  or other securities  equal to twice  the Purchase Price
(any of  the  events  described  in  this  paragraph  being  called  "Triggering
Events"). Any rights that are or were at any time on or after the earlier of the
Distribution  Date or the Stock Acquisition Date (as such term is defined in the
Rights Agreement), beneficially owned  by an Acquiring  Person will become  null
and  void upon the occurrence  of a Triggering Event and  any holder of any such
Right will be unable to exercise such Right after the occurrence of a Triggering
Event.
 
    At any time prior to  the earlier of (i) the  tenth day following the  Stock
Acquisition  Date or (ii) the  Final Expiration Date, the  Board of Directors of
the Company may redeem the Rights in whole, but not in part, at a price of  $.05
per Right.
 
    The  Purchase Price  payable, and  the number of  shares of  Common Stock or
other securities or property issuable, upon  exercise of the Rights are  subject
to  adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a  subdivision, combination or  reclassification of, the  Common
Stock,  (ii) upon  the grant  to holders  of Common  Stock of  certain rights or
warrants to subscribe for  shares of Common Stock  or convertible securities  at
less  than  the current  market  price of  the Common  Stock  or (iii)  upon the
distribution  to  holders  of  Common   Stock  of  evidences  of   indebtedness,
securities,  cash  or  assets  (excluding  regular  periodic  dividends)  or  of
subscription rights  or warrants  (other  than those  referred to  above).  With
certain  exceptions, no adjustment in the  Purchase Price will be required until
cumulative adjustments require  an adjustment  of at  least 1%  in the  Purchase
Price.
 
    The   Rights  have  certain  antitakeover  effects.  The  Rights  may  cause
substantial dilution to a person or  group that attempts to acquire the  Company
on  terms not  approved by  the Board  of Directors  of the  Company. The Rights
should not interfere with any merger  or other business combination approved  by
the  Board of  Directors of the  Company since the  Rights may be  redeemed at a
price of $.05 per Right  prior to the time that  a person or group has  acquired
beneficial ownership of 20% or more of the outstanding Common Stock.
 
    The Rights Agreement (the "Rights Agreement") dated as of April 14, 1987, as
amended  December 14, 1989, between the  Company and Chemical Bank (successor to
Manufacturers Hanover Trust Company),  as Rights Agent,  specifies the terms  of
the Rights. The foregoing description of the Rights
 
                                       26
<PAGE>
is  qualified in its entirety by reference to such Rights Agreement, which is an
exhibit to the  Company's registration statement  on Form 8-A,  dated April  17,
1987, as amended, incorporated by reference herein.

                  LIMITATIONS ON ISSUANCE OF BEARER SECURITIES
 
    In  compliance with United  States federal tax  laws and regulations, Bearer
Securities  (including  Debt  Securities   that  are  exchangeable  for   Bearer
Securities  and Debt Securities in permanent  global form that are either Bearer
Securities or  exchangeable for  Bearer Securities)  may not  be offered,  sold,
resold  or delivered  in connection with  their original issuance  in the United
States or to United States persons  (each as defined below) except as  otherwise
permitted  by Treasury  Regulation Section  1.163-5(c)(2)(i)(D) including offers
and sales  to  offices  located  outside the  United  States  of  United  States
financial    institutions   (as   defined   in   Treasury   Regulation   Section
1.165-12(c)(1)(v)) which agree  in writing  to comply with  the requirements  of
Section  165(j)(3)(A),(B)  or  (C)  of  the  Code,  as  defined  below,  and the
regulations thereunder, and any  underwriters, agents and dealers  participating
in  the offering  of Debt Securities  must agree  in writing that  they will not
offer, sell or resell any Bearer Securities to persons within the United  States
or  to  United States  persons (except  as described  above) nor  deliver Bearer
Securities within the United States. In addition, any such underwriters,  agents
and  dealers must represent in  writing that they have  in effect, in connection
with the offer and sale of  the Debt Securities, procedures reasonably  designed
to ensure that their employees or agents who are directly engaged in selling the
Debt  Securities are aware that Bearer Securities cannot be offered or sold to a
person who is within the  United States or is a  United States person except  as
otherwise   permitted  by   Treasury  Regulation   Section  1.163-5(c)(2)(i)(D).
Furthermore, the  owner  of the  obligation  (or the  financial  institution  or
clearing organization through which the owner holds the obligation) must certify
to  the Company that the owner is  not a United States Person. Bearer Securities
and any coupons  attached hereto  will bear  the following  legend: "Any  United
States person who holds this obligation will be subject to limitations under the
United  States income tax  laws, including the  limitations provided in Sections
165(j) and 1287(a) of the United States Internal Revenue Code."
 
    Purchasers of Bearer Securities may be affected by certain limitations under
United States  tax  laws. The  applicable  Prospectus Supplement  or  Prospectus
Supplements  will describe such  limitations for any  Bearer Securities relating
thereto.
 
    As used herein, "United States person"  means (i) an individual who is,  for
United  States federal income tax purposes, 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) an  estate or trust  the income of  which is subject  to United  States
federal  income taxation regardless of its source, and "United States" means the
United States of America  (including the States and  the District of  Columbia),
its territories and its possessions.
 
                              PLAN OF DISTRIBUTION
 
    The  Company may sell  Securities to or through  underwriters or dealers and
also may sell  Securities directly to  other purchasers or  through agents.  Any
such  underwriter or agent involved in the offer and sale of the Securities will
be named in an applicable Prospectus Supplement.
 
    Underwriters may offer and sell the  Securities at a fixed price or  prices,
which  may be changed, or  from time to time at  market prices prevailing at the
time of  sale,  at  prices  related  to such  prevailing  market  prices  or  at
negotiated   prices.  The  Company  also  may,  from  time  to  time,  authorize
underwriters acting as  the Company's agents  to offer and  sell the  Securities
upon the terms and conditions as
 
                                       29
<PAGE>
shall  be set forth in any Prospectus Supplement. In connection with the sale of
Securities, underwriters may be  deemed to have  received compensation from  the
Company  in the form of underwriting discounts or commissions from purchasers of
Securities for whom they may act  as agent. Underwriters may sell Securities  to
or  through dealers, and  such dealers may  receive compensation in  the form of
discounts, concessions or commissions  from the underwriters and/or  commissions
(which  may be changed from time to time)  from the purchasers for whom they may
act as agent.
 
    Any underwriting compensation paid by the Company to underwriters or  agents
in connection with the offering of Securities, and any discounts, concessions or
commissions  allowed by underwriters to participating dealers, will be set forth
in  an  applicable  Prospectus  Supplement.  Underwriters,  dealers  and  agents
participating  in  the  distribution  of  the Securities  may  be  deemed  to be
underwriters, and any discounts and commissions received by them and any  profit
realized  by them on resale  of the Securities may  be deemed to be underwriting
discounts and commissions, under the  Securities Act. Underwriters, dealers  and
agents  may be entitled,  under agreements with  the Company, to indemnification
against and contribution toward certain civil liabilities, including liabilities
under the  Securities Act,  and  to reimbursement  by  the Company  for  certain
expenses.
 
    If  so indicated  in an applicable  Prospectus Supplement,  the Company will
authorize dealers acting as  the Company's agents to  solicit offers by  certain
institutions  to purchase Debt Securities or Preferred Stock from the Company at
the public offering price  set forth in such  Prospectus Supplement pursuant  to
Delayed  Delivery Contracts ("Contracts") providing  for payment and delivery on
the date or dates  stated in such Prospectus  Supplement. Each Contract will  be
for  an amount specified  in the applicable  Prospectus Supplement. Institutions
with whom Contracts, when authorized, may be made include commercial and savings
banks, insurance companies, pension funds, investment companies, educational and
charitable institutions and other institutions, but will in all cases be subject
to the approval of the Company. Contracts will not be subject to any  conditions
except  (i) the  purchase by  an institution  of the  Securities covered  by its
Contracts shall not at the time of delivery be prohibited under the laws of  any
jurisdiction in the United States to which such institution is subject, and (ii)
if the Securities are being sold to underwriters, the Company shall have sold to
such  underwriters the amount specified in the applicable Prospectus Supplement.
Agents and underwriters will have no  responsibility in respect of the  delivery
or  performance  of  Contracts.  A commission  as  indicated  in  the applicable
Prospectus Supplement  will  be  paid  to  underwriters  and  agents  soliciting
purchases of Securities pursuant to Contracts accepted by the Company.
 
    Each  underwriter, dealer and agent participating in the distribution of any
Debt Securities which are issuable  in bearer form will  agree that it will  not
offer,  sell or deliver, directly or  indirectly, Debt Securities in bearer form
in the United States or to  United States persons except as otherwise  permitted
by Treasury Regulation Section 1.163-5(c)(2)(i)(D). See "Limitations on Issuance
of Bearer Securities."
 
    The  Securities may not be  offered or sold directly  or indirectly in Great
Britain other than  to persons  whose ordinary  business it  is to  buy or  sell
shares  or debentures (except in circumstances  which do not constitute an offer
to the  public within  the  meaning of  the Companies  Act  of 1985),  and  this
Prospectus and any Prospectus Supplement or any other offering material relating
to  the Securities may not be distributed in or from Great Britain other than to
persons whose business involves the acquisition and disposal, or the holding, of
securities whether as principal or as agent.
 
    Each series of Securities  will be a new  issue with no established  trading
market,  other  than the  Common Stock  which is  listed on  the New  York Stock
Exchange. Any Common  Stock sold  pursuant to  a Prospectus  Supplement will  be
listed  on the New York Stock Exchange,  subject to official notice of issuance.
Any underwriters to whom Securities are sold by the Company for public  offering
and sale may make a market in such Securities, but such underwriters will not be
obligated  to do so  and may discontinue  any market making  at any time without
notice. No assurance can be given as to the liquidity of the trading market  for
any Securities.
