$300,000,000
Medium-Term Notes, Series A
Due From Nine Months to 40 Years From Date of Issue
 
Olin Corporation (the "Company") may offer from time to time its Medium-Term
Notes, Series A (the "Notes", which term shall include Notes which are Senior
Securities ("Senior Notes") and Notes which are Subordinated Securities
("Subordinated Notes")), with an aggregate principal amount of up to
U.S. $300,000,000, or the equivalent thereof in other currencies, including
composite currencies (the "Specified Currency") such as the European Currency
Unit (ECU). Such aggregate offering price is subject to reduction as a result of
the sale by the Company of certain other Securities. See "Plan of Distribution."
Each Note will mature from nine months to forty years from its date of issue, as
agreed upon by the Company and the purchaser, and may be subject to redemption
prior to maturity at the option of the Company or repayment at the option of the
registered holder if set forth in the applicable Pricing Supplement. Each Note
will bear interest either at a fixed rate (a "Fixed Rate Note") established by
the Company at the date of issue of such Note, which may be zero in the case of
certain Original Issue Discount Notes, or at a floating rate (a "Floating Rate
Note"), as set forth therein and specified in the applicable Pricing Supplement.
A Fixed Rate Note may pay a level amount in respect of both interest and
principal amortized over the life of the Note (an "Amortizing Note"). The Notes
may be issued as Senior Notes or Subordinated Notes, as set forth in the
applicable Pricing Supplement. Subordinated Notes will be subordinated to all
Superior Indebtedness. See "Description of Debt Securities -- Subordination of
Subordinated Securities" in the accompanying Prospectus.
 
Unless otherwise specified in the applicable Pricing Supplement, interest on
each Fixed Rate Note will be payable each June 15 and December 15 and at
maturity. Interest on each Floating Rate Note will be payable on the dates set
forth herein and in the applicable Pricing Supplement. Unless otherwise
specified in the applicable Pricing Supplement, Amortizing Notes will pay
principal and interest semiannually each June 15 and December 15, or quarterly
each March 15, June 15, September 15 and December 15, and at maturity. Each
Fixed Rate Note will mature on a day from nine months to forty years from the
date of issue, as set forth in the applicable Pricing Supplement. Each Floating
Rate Note will mature on an Interest Payment Date from nine months to forty
years from the date of issue, as set forth in the applicable Pricing Supplement.
See "Description of Notes." Unless otherwise specified in the applicable Pricing
Supplement, the Notes may not be redeemed by the Company or the holder prior to
maturity. Notes denominated in U.S. dollars will be issued in denominations of
$100,000 or any amount in excess thereof which is an integral multiple of
$1,000. The authorized denominations of Notes not denominated in U.S. dollars
will be set forth in the applicable Pricing Supplement. Any terms relating to
Notes being denominated in foreign currencies or composite currencies will be
set forth in the applicable Pricing Supplement.
 
Each Note will be issued only in fully registered form and will be represented
either by a Global Security registered in the name of a nominee of The
Depository Trust Company, as Depositary (a "Book-Entry Note"), or by a
certificate issued in definitive form (a "Certificated Note"), as set forth in
the applicable Pricing Supplement. Beneficial interests in Global Securities
representing Book-Entry Notes will be shown on, and transfer thereof will be
effected through, the records maintained by the Depositary (with respect to
participants' interests) and its participants. Book-Entry Notes will not be
issuable as Certificated Notes except as described under "Description of Debt
Securities -- Global Securities" in the accompanying Prospectus.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT, ANY SUPPLEMENT HERETO OR THE
PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                              DESCRIPTION OF NOTES
 
     The following description of the particular terms of the Notes offered
hereby supplements, and to the extent inconsistent therewith replaces, the
description of the general terms and provisions of the Debt Securities set forth
under the heading "Description of Debt Securities" in the accompanying
Prospectus, to which reference is hereby made. The particular terms of the Notes
sold pursuant to any pricing supplement (a "Pricing Supplement") will be
described therein. The terms and conditions set forth in "Description of Notes"
will apply to each Note unless otherwise specified in the applicable Pricing
Supplement and in such Note. Capitalized terms not defined herein shall have the
same meanings assigned to such terms in the Prospectus or the applicable
Indenture. References herein to "U.S. dollars" or "U.S.$" or "$" are to the
currency of the United States of America.
 
GENERAL
 
     The Notes offered hereby, if Senior Securities, will be issued under the
Senior Indenture, as amended or supplemented. Notes issued under the Senior
Indenture will rank pari passu with all other unsecured and unsubordinated
indebtedness of the Company. Notes issued under the Subordinated Indenture will
be subordinated in right of payment to the prior payment in full of the Superior
Indebtedness of the Company. See "Description of Debt Securities Subordination
of Subordinated Securities" in the accompanying Prospectus. As of December 31,
1993, the Company had approximately $465 million of Superior Indebtedness
outstanding. The following description of the Notes will apply unless otherwise
specified in an applicable Pricing Supplement.
 
     The Notes will be offered on a continuous basis. The Notes issued under the
Senior Indenture and Subordinated Indenture will constitute all or part of a
single series for purposes of such Indentures. The Notes of such series offered
hereby are limited to an aggregate initial offering price of U.S. $300,000,000
(or the equivalent thereof in one or more Specified Currencies), subject to
reduction as a result of the sale by the Company of certain other Securities
referred to in the accompanying Prospectus. See "Plan of Distribution" herein
and in the accompanying Prospectus. For purposes of this Prospectus Supplement,
(i) the principal amount of any Original Issue Discount Note (as defined below)
means the Issue Price (as defined below) of such Note and (ii) the principal
amount of any Note issued in the Specified Currency means the U.S. dollar
equivalent on the date of issue of the Issue Price of such Note.
 
     Each Note will mature from nine months to forty years from its date of
issue, as selected by the initial purchaser and agreed to by the Company, and
may be subject to redemption at the option of the Company or repayment at the
option of the holder prior to its Stated Maturity (as defined herein) if set
forth in the applicable Pricing Supplement. See "Optional Redemption" and
"Repayment at the Noteholders' Option" below. Fixed Rate Notes, Amortizing Notes
and Original Issue Discount Notes will mature on any day from nine months to
forty years from the date of issue, as set forth in the applicable Pricing
Supplement. Unless otherwise specified in the applicable Pricing Supplement,
Floating Rate Notes will mature on an Interest Payment Date (as defined below)
from nine months to forty years from the date of issue, as set forth in the
applicable Pricing Supplement.
 
     Each Note will be issued initially as either a Book-Entry Note or a
Certificated Note. The Company currently contemplates that only Notes
denominated and payable solely in U.S. dollars will be issued as Book-Entry
Notes. Except as set forth under "Description of Debt Securities -- Global
Securities" in the accompanying Prospectus, Book-Entry Notes will not be
issuable as Certificated Notes. See "Book-Entry System" below.
 
     Unless otherwise specified 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. Except for Notes
not denominated in U.S. dollars or as otherwise provided in the applicable
Pricing Supplement, the Notes will be issued only in fully registered form in
denominations of U.S. $100,000 or any amount in excess thereof which is an
integral multiple of U.S. $1,000. If any of the Notes are to be denominated in a
Specified Currency other than U.S. dollars, additional information pertaining to
the terms of
 
                                       S-3
<PAGE>   6
 
such Notes and other matters relevant to the holders thereof will be described
in the applicable Pricing Supplement.
 
     The Notes may be issued as Original Issue Discount Notes (including Zero
Coupon Notes), as indicated in the applicable Pricing Supplement. An "Original
Issue Discount Note" means any Note that provides for an amount more than the
principal amount thereof to be due and payable upon a declaration of
acceleration of the maturity thereof pursuant to the applicable Indenture. See
"Certain United States Federal Income Tax Consequences -- United States
Holders -- Original Issue Discount" below.
 
     The Notes may be issued as Indexed Notes, as indicated in the applicable
Pricing Supplement. See "Indexed Notes" below.
 
     The Pricing Supplement relating to each Note will specify the price
(expressed as a percentage of the aggregate principal amount thereof) at which
such Note will be issued if other than 100% (the "Issue Price"), the principal
amount, the interest rate or interest rate formula, ranking, maturity, currency
or composite currency, any redemption or repayment provisions and any other
terms on which each such Note will be issued that are not inconsistent with the
provisions of the applicable Indenture.
 
     Unless otherwise specified in the applicable Pricing Supplement, the Notes
will not be subject to any sinking fund.
 
     Book-Entry Notes may be transferred or exchanged only through the
Depositary, see "Book-Entry System" below. The Certificated Notes may be
presented for registration of transfer or exchange at the corporate trust office
of the Trustee in the Borough of Manhattan, The City of New York, in the case of
Senior Securities, and at the corporate trust office maintained for such purpose
by the Trustee under the Subordinated Indenture, in the case of Subordinated
Securities.
 
     As used herein, "Business Day" shall mean any day, other than a Saturday or
Sunday, that is neither a legal holiday nor a day on which banking institutions
are generally authorized or required by law or regulation to close in The City
of New York and (i) in respect of LIBOR Notes (as defined below), in the City of
London and which is a London Banking Day, (ii) with respect to Notes denominated
or payable in a Specified Currency other than ECUs, in the financial center of
the country issuing the Specified Currency and (iii) with respect to Notes
denominated or payable in ECUs, in the financial center of each country that
issues a component currency of the ECU, and that is not a non-ECU settlement
day. "London Banking Day" shall mean any day on which dealings in deposits in
U.S. dollars are transacted in the London interbank market.
 
     As used herein, an "Interest Payment Date" with respect to any Note shall
be a date on which, under the terms of such Note, regularly scheduled interest
shall be payable. Unless otherwise specified in the applicable Pricing
Supplement, "Record Date" with respect to any Interest Payment Date shall be the
date fifteen calendar days (whether or not such date is a Business Day) prior to
such Interest Payment Date.
 
PAYMENT CURRENCY AND CURRENCY EXCHANGE INFORMATION
 
     Purchasers are required to pay for Notes denominated in a Specified
Currency in such Specified Currency, and payments of principal of, premium, if
any, and interest on such Notes will be made in such Specified Currency, unless
otherwise provided in the applicable Pricing Supplement. Currently, there are
limited facilities in the United States for the conversion of U.S. dollars and
foreign currencies. In addition, most banks do not currently offer non-U.S.
dollar denominated checking or savings account facilities in the United States.
Accordingly, unless otherwise specified in the applicable Pricing Supplement, or
unless alternative arrangements are made, payment of principal of, premium, if
any, and interest on Notes in a Specified Currency other than U.S. dollars will
be made to an account at a bank outside the United States.
 
     If the applicable Pricing Supplement provides for payments of principal of,
premium, if any, and interest on a non-U.S. dollar denominated Note to be made
in U.S. dollars or for payments of principal of, premium, if any, and interest
on a U.S. dollar denominated Note to be made in a Specified Currency other than
U.S. dollars, the conversion of the Specified Currency into U.S. dollars or U.S.
dollars into the Specified Currency, as the case may be, will be made by the
Exchange Rate Agent identified in the applicable Pricing
 
                                       S-4

Supplement. The costs of such conversion will be borne by the holder of such
Note through deductions from such payments.
 
     If the applicable Pricing Supplement provides for payments of principal of,
premium, if any, and interest on a non-U.S. dollar denominated Note to be made,
at the option of the holder of such Note, in U.S. dollars, conversion of the
Specified Currency into U.S. dollars 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 unless the Exchange Rate Agent is the
applicable Agent) 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 the holders of Notes 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 holders of Notes by deductions from such
payments.
 
     Except as set forth below, if the principal of, premium, if any, or
interest on a Note is payable in a Specified Currency other than U.S. dollars
and such Specified Currency is not available to the Company for making payments
thereof due to the imposition of exchange controls or other circumstances beyond
the control of the Company or is no longer used by the government of the country
issuing such currency or for the settlement of transactions by public
institutions within the international banking community, then the Company will
be entitled to satisfy its obligations to holders of the Notes by making such
payments in U.S. dollars on the basis of the Market Exchange Rate as defined in
the applicable Pricing Supplement on the date of such payment or, if the Market
Exchange Rate is not available on such date, as of the most recent practicable
date. Any payment made under such circumstances in U.S. dollars where the
required payment is in a Specified Currency other than U.S. dollars will not
constitute an Event of Default under the applicable Indenture.
 
     If payment in respect of a Note is required to be made in ECUs and ECUs are
unavailable due to the imposition of exchange controls or other circumstances
beyond the Company's control or are no longer used in the European Monetary
System, then all payments in respect of such Note shall be made in U.S. dollars
until ECUs are again available or so used. The amount of each payment in U.S.
dollars shall be computed on the basis of the equivalent of the ECU in U.S.
dollars, determined as described below, as of the second Business Day prior to
the date on which such payment is due.
 
     The equivalent of the ECU in U.S. dollars as of any date shall be
determined by the Company or its agent on the following basis. The component
currencies of the ECU for this purpose (the "Components") shall be the currency
amounts that were components of the ECU as of the last date on which the ECU was
used in the European Monetary System. The equivalent of the ECU in U.S. dollars
shall be calculated by aggregating the U.S. dollar equivalents of the
Components. The U.S. dollar equivalent of each of the Components shall be
determined by the Company or such agent on the basis of the most recently
available Market Exchange Rates for such Components.
 
     If the official unit of any Component is altered by way of combination or
subdivision, the number of units of that currency as a Component shall be
divided or multiplied in the same proportion. If two or more Components are
consolidated into a single currency, the amounts of those currencies as
Components shall be replaced by an amount in such single currency equal to the
sum of the appropriate amounts of the consolidated component currencies
expressed in such single currency. If any Component is divided into two or more
currencies, the amount of the original component currency shall be replaced by
the appropriate amounts of such two or more currencies, the sum of which shall
be equal to the amount of the original component currency.
 
     For a description of risks relating to foreign currencies, see "Foreign
Currency Risks" below.
 
     All determinations referred to above made by the Company or its agent shall
be at the Company's sole discretion and shall, in the absence of manifest error,
be conclusive for all purposes and binding on holders of Notes.

INTEREST AND PRINCIPAL PAYMENTS
 
     Payments of principal of, and premium and interest, if any, on Book-Entry
Notes will be made by the Company through the Trustee to the Depositary. See
"Book-Entry System" below. With respect to Certificated Notes, interest will be
payable to the person in whose name the Certificated Note is registered at the
close of business on the applicable Record Date; provided that the interest
payable upon maturity, redemption or repayment (whether or not the date of
maturity, redemption or repayment is an Interest Payment Date) will be payable
to the person to whom principal is payable. Unless otherwise specified in the
applicable Pricing Supplement, the initial interest payment on a Note will be
made on the first Interest Payment Date falling after the date the Note is
issued; provided, however, that payments of interest (or, in the case of an
Amortizing Note, principal and interest) on a Note issued less than 15 calendar
days before an Interest Payment Date will be paid on the next succeeding
Interest Payment Date to the holder of record on the Record Date with respect to
such succeeding Interest Payment Date, unless otherwise specified in the
applicable Pricing Supplement. See "Certain United States Federal Income Tax
Consequences -- United States Holders -- Payments of Interest" below.
 
     Payments of principal of, premium, if any, and interest payable at
maturity, redemption or repayment on Certificated Notes, other than Certificated
Notes payable in a Specified Currency, will be made in immediately available
funds at the corporate trust office of the Trustee in the Borough of Manhattan,
The City of New York, in the case of Certificated Notes which are Senior
Securities, and at the corporate trust office maintained for such purpose by the
Trustee under the Subordinated Indenture in the case of Certificated Notes which
are Subordinated Securities, 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. Payment of interest (other than at
maturity, redemption or repayment) may be made by check mailed to the person
entitled thereto or, at the option of the Company, by wire transfer to an
account maintained by such person with a bank located in the United States.
Notwithstanding the foregoing, a holder of $10,000,000 or more in aggregate
principal amount of Notes of like tenor and terms (or the holder of the
equivalent thereof in a Specified Currency other than U.S. dollars) shall be
entitled to receive interest payments (other than at maturity, redemption or
repayment) by wire transfer in immediately available funds, but only if
appropriate instructions have been received in writing by the Paying Agent on or
prior to the applicable Record Date for such payment of interest.
 
     Unless otherwise specified in the applicable Pricing Supplement or unless
alternative arrangements are made, payments of principal of, premium, if any,
and interest on a Note in a Specified Currency will be made by wire transfer of
immediately available funds to an account maintained by the payee with a bank
located outside the United States if the holder of such Notes provides the
Paying Agent with the appropriate wire transfer instructions not later than 15
calendar days prior to the applicable payment date. If such wire transfer
instructions are not so provided, payments of principal of, premium, if any, and
interest on such Notes will be made by check payable in such Specified Currency
mailed to the address of the person entitled thereto as such address shall
appear in the Note register.
 
     Certain Notes, including Original Issue Discount Notes, may be considered
to be issued with original issue discount, which must be included in income for
United States Federal income tax purposes at a constant rate. Unless otherwise
specified in the applicable Pricing Supplement, if the principal of any Original
Issue Discount Note is declared to be due and payable immediately, the amount of
principal due and payable with respect to such Note shall be limited to the
aggregate principal amount of such Note multiplied by the sum of its Issue Price
(expressed as a percentage of the aggregate principal amount) plus the original
issue discount amortized from the date of issue to the date of declaration,
which amortization shall be calculated using the "interest method" (computed in
accordance with generally accepted accounting principles in effect on the date
of declaration). Special considerations applicable to any such Notes will be set
forth in the applicable Pricing Supplement. See "Certain United States Federal
Income Tax Consequences -- United States Holders -- Original Issue Discount"
below.

FIXED RATE NOTES
 
     Each Fixed Rate Note will bear interest from the date of issuance at the
annual rate stated on the face thereof, except as described below under
"Extension of Maturity," until the principal thereof is paid or made available
for payment. Unless otherwise specified in the applicable Pricing Supplement,
such interest will be computed on the basis of a 360-day year of twelve 30-day
months. Unless otherwise specified in the applicable Pricing Supplement,
payments of interest on Fixed Rate Notes other than Amortizing Notes will be
made semiannually on each June 15 and December 15 and at maturity or upon any
earlier redemption or repayment. Unless otherwise specified in the applicable
Pricing Supplement, payments of principal of and interest on Amortizing Notes,
which are securities on which payments of principal and interest are made in
equal installments over the life of the security, will be made either quarterly
on each March 15, June 15, September 15 and December 15 or semiannually on each
June 15 and December 15, as set forth in the applicable Pricing Supplement, and
at maturity or upon any earlier redemption or repayment. Payments with respect
to Amortizing Notes will be applied first to interest due and payable thereon
and then to the reduction of the unpaid principal amount thereof. A table
setting forth repayment information in respect of each Amortizing Note will be
provided to the original purchaser and will be available, upon request, to
subsequent holders.
 
     If any Interest Payment Date for any Fixed Rate Note would fall on a day
that is not a Business Day, the interest payment shall be postponed to the next
day that is a Business Day, and no interest on such payment shall accrue for the
period from and after the Interest Payment Date. If the maturity date (or date
of redemption or repayment) of any Fixed Rate Note would fall on a day that is
not a Business Day, the payment of principal, premium, if any, and interest may
be made on the next succeeding Business Day, and no interest on such payment
shall accrue for the period from and after the maturity date (or date of
redemption or repayment).
 
     Interest payments for Fixed Rate Notes will include accrued interest from
the date of issue or from the last date in respect of which interest has been
paid or duly provided for, as the case may be, to, but excluding, the Interest
Payment Date or the date of maturity or earlier redemption or repayment, as the
case may be.
 
FLOATING RATE NOTES
 
     Each Floating Rate Note will bear interest from the date of issuance until
the principal thereof is paid or made available for payment at a rate determined
by reference to an interest rate basis (the "Base Rate"), which may be adjusted
by a Spread and/or Spread Multiplier (each as defined below). The applicable
Pricing Supplement will designate one or more of the following Base Rates as
applicable to each Floating Rate Note: (a) the CD Rate (a "CD Rate Note"), (b)
the Commercial Paper Rate (a "Commercial Paper Rate Note"), (c) the Federal
Funds Rate (a "Federal Funds Rate Note"), (d) LIBOR (a "LIBOR Note"), (e) the
Prime Rate (a "Prime Rate Note"), (f) the Treasury Rate (a "Treasury Rate Note")
or (g) such other Base Rate as is set forth in such Pricing Supplement and in
such Floating Rate Note. The "Index Maturity" for any Floating Rate Note is the
designated maturity of the instrument or obligation from which the Base Rate is
calculated as specified in the applicable Pricing Supplement.
 
     Unless otherwise specified in the applicable Pricing Supplement, the
interest rate on each Floating Rate Note will be calculated by reference to the
specified Base Rate (i) plus or minus the Spread, if any, and/or (ii) multiplied
by the Spread Multiplier, if any. The "Spread" is the number of basis points
(one basis point equals one-hundredth of a percentage point) specified in the
applicable Pricing Supplement to be added to or subtracted from the Base Rate
for such Floating Rate Note, and the "Spread Multiplier" is the percentage
specified in the applicable Pricing Supplement by which the Base Rate will be
multiplied to determine the applicable interest rate for such Floating Rate
Note.
 
     As specified in the applicable Pricing Supplement, a Floating Rate Note may
also have either or both of the following: (i) a maximum limitation, or ceiling,
on the rate of interest which may accrue during any interest period ("Maximum
Interest Rate"); and (ii) a minimum limitation, or floor, on the rate of
interest which may accrue during any interest period ("Minimum Interest Rate").
In addition to any Maximum Interest Rate that may be applicable to any Floating
Rate Note pursuant to the above provisions, the interest rate on a Floating Rate
Note will in no event be higher than the maximum rate permitted by New York law,
 
                                       S-7
<PAGE>   10
 
as the same may be modified by United States law of general application. Under
current New York law, the maximum rate of interest is 25% per annum on a simple
interest basis. The limit may not apply to Floating Rate Notes in which an
investor has invested $2,500,000 or more.
 
     Unless otherwise specified in the applicable Pricing Supplement, the rate
of interest on each Floating Rate Note will be reset daily, weekly, monthly,
quarterly, semiannually or annually (such period being the "Interest Reset
Period" for such Note, and the first day of each Interest Reset Period being an
"Interest Reset Date"), as specified in the applicable Pricing Supplement.
Unless otherwise specified in the applicable Pricing Supplement, the Interest
Reset Date will be: (i) in the case of Floating Rate Notes which reset daily,
each Business Day; (ii) in the case of Floating Rate Notes (other than Treasury
Rate Notes) which reset weekly, the Wednesday of each week; (iii) in the case of
Treasury Rate Notes which reset weekly, the Tuesday of each week, except as
provided below under "Treasury Rate Notes"; (iv) in the case of Floating Rate
Notes which reset monthly, the third Wednesday of each month; (v) in the case of
Floating Rate Notes which reset quarterly, the third Wednesday of March, June,
September and December; (vi) in the case of Floating Rate Notes which reset
semiannually, the third Wednesday of two months of each year, as specified in
the applicable Pricing Supplement; and (vii) in the case of Floating Rate Notes
which reset annually, the third Wednesday of one month of each year, as
specified in the applicable Pricing Supplement; provided, however, that (a) the
interest rate in effect from the date of issue to the first Interest Reset Date
with respect to a Floating Rate Note will be the initial interest rate set forth
in the applicable Pricing Supplement (the "Initial Interest Rate") and (b)
unless otherwise specified in the applicable Pricing Supplement, the interest
rate in effect for the ten days immediately prior to maturity, redemption or
repayment will be that in effect on the tenth day preceding such maturity,
redemption or repayment date. If any Interest Reset Date for any Floating Rate
Note would otherwise be a day that is not a Business Day, such Interest Reset
Date shall be postponed to the next succeeding Business Day, except that, in the
case of a LIBOR Note, if such Business Day is in the next succeeding calendar
month, such Interest Reset Date shall be the next preceding Business Day.
 
     Except as provided below, unless otherwise specified in the applicable
Pricing Supplement, interest on Floating Rate Notes will be payable: (i) in the
case of Floating Rate Notes with a daily, weekly or monthly Interest Reset Date,
on the third Wednesday of each month; (ii) in the case of Floating Rate Notes
with a quarterly Interest Reset Date, on the third Wednesday of March, June,
September and December; (iii) in the case of Floating Rate Notes with a
semiannual Interest Reset Date, the third Wednesday of the two months specified
in the applicable Pricing Supplement; and (iv) in the case of Floating Rate
Notes with an annual Interest Reset Date, the third Wednesday of the month
specified in the applicable Pricing Supplement and, in each case, at maturity,
redemption or repayment. If any Interest Payment Date for any Floating Rate Note
would fall on a day that is not a Business Day with respect to such Floating
Rate Note, such Interest Payment Date will be the following day that is a
Business Day with respect to such Floating Rate Note, except that, in the case
of a LIBOR Note, if such Business Day is in the next succeeding calendar month,
such Interest Payment Date shall be the immediately preceding day that is a
Business Day with respect to such LIBOR Note. If the maturity date or any
earlier redemption or repayment date of a Floating Rate Note would fall 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 for the period from and after such maturity,
redemption or repayment date, as the case may be.
 
     Unless otherwise specified in the applicable Pricing Supplement, interest
payments for Floating Rate Notes (except Floating Rate Notes on which interest
is reset daily or weekly) shall be the amount of interest accrued from and
including the date of issue, or from and including the last date to which
interest has been paid to or duly provided for, to but excluding the Interest
Payment Date. In the case of a Floating Rate Note on which interest is reset
daily or weekly, interest payments shall be, unless otherwise specified in the
applicable Pricing Supplement, the amount of interest accrued from the date of
issue, or from and including the last date to which interest has been paid or
duly provided for, as the case may be, to and including the Record Date
immediately preceding such Interest Payment Date, except that at maturity or
earlier redemption or repayment, the interest payable will include interest
accrued to, but excluding, the maturity, redemption or repayment date, as the
case may be.
 
                                       S-8
<PAGE>   11
 
     With respect to a Floating Rate Note, accrued interest shall be calculated
by multiplying the principal amount of such Floating Rate Note by an accrued
interest factor. Such accrued interest factor will be computed by adding the
interest factors calculated for each day in the period for which interest is
being paid. Unless otherwise specified in the applicable Pricing Supplement, the
interest factor for each such day is computed by dividing the interest rate
applicable to such day by 360, in the case of CD Rate Notes, Commercial Paper
Rate Notes, Federal Funds Rate Notes, LIBOR Notes and Prime Rate Notes, or by
the actual number of days in the year, in the case of Treasury Rate Notes.
 
     The interest rate in effect on each day will be (a) if such day is an
Interest Reset Date, the interest rate with respect to the Interest
Determination Date (as defined below) pertaining to such Interest Reset Date, or
(b) if such day is not an Interest Reset Date, the interest rate with respect to
the Interest Determination Date pertaining to the immediately preceding Interest
Reset Date, subject in either case to any Maximum or Minimum Interest Rate
limitation referred to above and to any adjustment by a Spread and/or a Spread
Multiplier referred to above; provided, however, that (i) the interest rate in
effect for the period from the date of issue to the first Interest Reset Date
set forth in the applicable Pricing Supplement with respect to a Floating Rate
Note will be the "Initial Interest Rate" specified in the applicable Pricing
Supplement; and (ii) unless otherwise specified in the applicable Pricing
Supplement, the interest rate in effect for ten calendar days immediately prior
to maturity will be that in effect on the tenth calendar day preceding such
maturity.
 
     All percentages used in or resulting from any calculation of the rate of
interest on a Floating Rate Note will be rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point, with five one-millionths of a
percentage point rounded upward, and all dollar amounts used in or resulting
from such calculation on Floating Rate Notes will be rounded to the nearest
cent, with one-half cent rounded upward.
 
     The applicable Pricing Supplement shall specify a calculation agent (the
"Calculation Agent") with respect to any issue of Floating Rate Notes. Upon the
request of the holder of any Floating Rate Note, the Calculation Agent will
provide the interest rate then in effect and, if determined, the interest rate
that will become effective on the next Interest Reset Date with respect to such
Floating Rate Note.
 
     The "Interest Determination Date" pertaining to an Interest Reset Date for
CD Rate Notes, Commercial Paper Rate Notes, Federal Funds Rate Notes and Prime
Rate Notes will be the second Business Day next preceding such Interest Reset
Date. The Interest Determination Date pertaining to an Interest Reset Date for a
LIBOR Note will be the second London Banking Day preceding such Interest Reset
Date. The Interest Determination Date pertaining to an Interest Reset Date for a
Treasury Rate Note will be the day of the week on which such Interest Reset Date
falls on which Treasury bills of the specified index maturity would normally be
auctioned. Treasury bills are normally sold at auction on Monday of each week,
unless that day is a legal holiday, in which case the auction is normally held
on the following Tuesday, but such auction may be held on the preceding Friday.
If, as the result of a legal holiday, an auction is so held on the preceding
Friday, such Friday will be the Interest Determination Date pertaining to the
Interest Reset Date occurring in the next succeeding week. If an auction falls
on a day that is an Interest Reset Date, such Interest Reset Date will be the
next following Business Day.
 
     Unless otherwise specified in the applicable Pricing Supplement, the
"Calculation Date," where applicable, pertaining to an Interest Determination
Date will be the earlier of the tenth calendar day after such Interest
Determination Date or the next succeeding Record Date after such Interest
Determination Date or, if either such day is not a Business Day, the next
succeeding Business Day.
 
     Interest rates will be determined (which determination, in the absence of
manifest error, will be conclusive for all purposes and binding on holders of
Notes) by the Calculation Agent as follows:
 
CD Rate Notes
 
     CD Rate Notes will bear interest at the interest rate (calculated with
reference to the CD Rate and the Spread and/or Spread Multiplier, if any, and
subject to the Minimum Interest Rate and the Maximum Interest Rate, if any)
specified in each CD Rate Note and in the applicable Pricing Supplement.
 
                                       S-9
<PAGE>   12
 
     Unless otherwise specified in the applicable Pricing Supplement, "CD Rate"
means, with respect to any Interest Determination Date, the rate on such date
for negotiable certificates of deposit having the Index Maturity designated 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," or any successor publication of the Board of Governors of the Federal
Reserve System ("H.15(519)") under the heading "CDs (Secondary Market)," or, if
not so published by 3:00 p.m., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, the CD Rate will be the rate on
such Interest Determination Date for negotiable certificates of deposit of the
Index Maturity designated 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" (the "Composite
Quotations") under the heading "Certificates of Deposit." If such rate is not
yet published in either H.15(519) or the Composite Quotations by 3:00 p.m., New
York City time, on the Calculation Date pertaining to such Interest
Determination Date, the CD Rate on such Interest Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean of the
secondary market offered rates as of 10:00 a.m., New York City time, on such
Interest Determination Date for certificates of deposit in the denomination of
$5,000,000 with a remaining maturity closest to the Index Maturity designated in
the applicable Pricing Supplement of three leading nonbank dealers in 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 center banks of the highest credit standing in the market for negotiable
certificates of deposit; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as set forth above, the CD
Rate in effect for the applicable period will be the same as the CD Rate for the
immediately preceding Interest Reset Period (or, if there was no such Interest
Reset Period, the rate of interest payable on the CD Rate Notes for which such
CD Rate is being determined shall be the Initial Interest Rate).
 
Commercial Paper Rate Notes
 
     Commercial Paper Rate Notes will bear interest at the interest rate
(calculated with reference to the Commercial Paper Rate and the Spread and/or
Spread Multiplier, if any, and subject to the Minimum Interest Rate and the
Maximum Interest Rate, if any) specified in each Commercial Paper Rate Note and
in the applicable Pricing Supplement.
 
     Unless otherwise specified in the applicable Pricing Supplement,
"Commercial Paper Rate" means, with respect to any Interest Determination Date,
the Money Market Yield (as defined below) of the rate on such date for
commercial paper having the Index Maturity specified in the applicable Pricing
Supplement, as such rate shall be published in H.15(519), under the heading
"Commercial Paper." In the event that such rate is not published by 3:00 p.m.,
New York City time, on the Calculation Date pertaining to such Interest
Determination Date, then the Commercial Paper Rate shall be the Money Market
Yield of the rate on such Interest Determination Date for commercial paper of
the specified Index Maturity as published in the 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 available in either H.15(519) or the
Composite Quotations, then the Commercial Paper Rate shall be the Money Market
Yield of the arithmetic mean of the offered rates as of 11:00 a.m., New York
City time, on such Interest Determination Date of three leading dealers of
commercial paper in The City of New York selected by the Calculation Agent for
commercial paper of the specified Index Maturity, placed for an industrial
issuer whose bond rating is "AA," or the equivalent, from a nationally
recognized rating agency; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting offered rates as mentioned in
this sentence, the Commercial Paper Rate in effect for the applicable period
will be the same as the Commercial Paper Rate for the immediately preceding
Interest Reset Period (or, if there was no such Interest Reset Period, the rate
of interest payable on the Commercial Paper Rate Notes for which such Commercial
Paper Rate is being determined shall be the Initial Interest Rate).
 
     "Money Market Yield" shall be a yield calculated in accordance with the
following formula:
 
                           D x 360
  Money Market Yield =  360 - (D x M)  x 100

 
                                      S-10
<PAGE>   13
 
where "D" refers to the applicable 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.
 
Federal Funds Rate Notes
 
     Federal Funds Rate Notes will bear interest at the interest rate
(calculated with reference to the Federal Funds Rate and the Spread and/or
Spread Multiplier, if any, and subject to the Minimum Interest Rate and the
Maximum Interest Rate, if any) specified in each Federal Funds Rate Note and in
the applicable Pricing Supplement.
 
     Unless otherwise specified in the applicable Pricing Supplement, the
"Federal Funds Rate" means, with respect to any Interest Determination Date, the
rate on such date for Federal funds as published in H.15(519) under the heading
"Federal Funds (Effective)," or, if not so published by 3:00 p.m., New York City
time, on the Calculation Date pertaining to such Interest Determination Date,
the Federal Funds Rate will be the rate on such Interest Determination Date
published in the Composite Quotations under the heading "Federal Funds/Effective
Rate." if such rate is not yet published in either H.15(519) or the Composite
Quotations by 3:00 p.m., New York City time, on the Calculation Date pertaining
to such Interest Determination Date, the Federal Funds Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
arithmetic mean of the rates for the last transaction in overnight Federal
funds, as of 11:00 a.m., New York City time, on such Interest Determination
Date, arranged by three leading brokers of Federal funds transactions in The
City of New York selected by the Calculation Agent; provided, however, that if
the brokers selected as aforesaid by the Calculation Agent are not quoting as
set forth above, the Federal Funds Rate in effect for the applicable period will
be the same as the Federal Funds Rate for the immediately preceding Interest
Reset Period (or, if there was no such Interest Reset Period, the rate of
interest payable on the Federal Funds Rate Notes for which such Federal Funds
Rate is being determined shall be the Initial Interest Rate).
 
LIBOR Notes
 
     LIBOR Notes will bear interest at the interest rate (calculated with
reference to LIBOR and the Spread and/or Spread Multiplier, if any, and subject
to the Minimum Interest Rate and the Maximum Interest Rate, if any) specified in
each LIBOR Note and in the applicable Pricing Supplement.
 
     Unless otherwise specified in the applicable Pricing Supplement, "LIBOR"
for each Interest Determination Date will be determined by the Calculation Agent
as follows:
 
          (i) On each Interest Determination Date relating to a LIBOR Note,
     LIBOR will be (a) where the applicable Pricing Supplement specifies
     LIBOR-Telerate (as defined below) as the method for determining LIBOR, the
     rate for deposits in U.S. dollars having the Index Maturity specified in
     the applicable Pricing Supplement which appears on the Telerate Page 3750
     (as defined below) as of 11:00 a.m., London time, on such Interest
     Determination Date ("LIBOR-Telerate") or (b) where the applicable Pricing
     Supplement specifies LIBOR-Reuters (as defined below) as the method of
     determining LIBOR, the arithmetic mean of the offered rates for deposits in
     U.S. dollars having the Index Maturity specified in the applicable Pricing
     Supplement which appear on the Reuters Screen LIBO Page (as defined below)
     as of 11:00 a.m., London time, on such Interest Determination Date,
     provided that at least two such offered rates appear on the Reuters Screen
     LIBO Page ("LIBOR-Reuters"); provided, however, that if the method for
     determining LIBOR with respect to any LIBOR Note is not specified therein
     or in the applicable Pricing Supplement, "LIBOR" means LIBOR-Telerate.
 
          (ii) If on any Interest Determination Date, (x) in any case where
     LIBOR-Telerate applies, the rate for deposits in U.S. dollars having the
     applicable Index Maturity does not appear on the Telerate Page 3750 as
     specified in (i)(a) above, or (y) in any case where LIBOR-Reuters applies,
     fewer than two offered rates for deposits in U.S. dollars having the
     applicable Index Maturity appear on the Reuters Screen LIBO Page as
     specified in (i)(b) above, LIBOR 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
 
                                      S-11
<PAGE>   14
 
     by the Calculation Agent at approximately 11:00 a.m., London time, on such
     Interest Determination Date to prime banks in the London interbank market
     having the Index Maturity specified in the applicable Pricing Supplement
     and in a principal amount equal to an amount that is representative for a
     single transaction in such market at such time. The Calculation Agent will
     request the principal London office of each of such banks to provide a
     quotation of its rate. If at least two such quotations are provided, the
     rate in respect of such Interest Determination Date will be the arithmetic
     mean of the quotations. If fewer than two quotations are provided, LIBOR in
     respect of such Interest Determination 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
     such Interest Determination Date for loans in U.S. dollars to leading
     European banks, having the Index Maturity specified in the applicable
     Pricing Supplement and in a principal amount equal to an amount that is
     representative for a single transaction in such market at such time;
     provided however, that if the banks selected as aforesaid by the
     Calculation Agent are not quoting as described in this sentence, LIBOR for
     such Interest Reset Period will be the same as LIBOR for the immediately
     preceding Interest Reset Period (or, if there was no such Interest Reset
     Period, the rate of interest payable on the LIBOR Notes for which LIBOR is
     being determined shall be the Initial Interest Rate).
 
     "Telerate Page 3750" means the display page designated as page 3750 on the
Dow Jones Telerate Service (or such other page as may replace page 3750 on that
service for the purpose of displaying London interbank offered rates).
 
     "Reuters Screen LIBO Page" means the display page designated as page "LIBO"
on the Reuters Monitor Money Rates Service (or such other page as may replace
the LIBO page on that service for the purpose of displaying London interbank
offered rates).
 
Prime Rate Notes
 
     Prime Rate Notes will bear interest at the interest rate (calculated with
reference to the Prime Rate and the Spread and/or Spread Multiplier, if any, and
subject to the Minimum Interest Rate and the Maximum Interest Rate, if any)
specified in each 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, the rate published
in H. 15(519) for such date opposite the caption "Bank Prime Loan." If such rate
is not yet published by 3:00 p.m., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, the Prime Rate for such Interest
Determination Date will be the arithmetic mean of the rates of interest publicly
announced by each bank named on the Reuters Screen NYMF Page (as defined below)
as such bank's prime rate or base lending rate as in effect for such Interest
Determination Date as quoted on the Reuters Screen NYMF Page on such Interest
Determination Date, or, if fewer than four such rates appear on the Reuters
Screen NYMF Page for such Interest Determination Date, the 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 360 as of the close of business on such Interest
Determination Date by at least two of the three major money center banks in The
City of New York selected by the Calculation Agent from which quotations are
requested. If fewer than two quotations are provided, the Prime Rate shall be
calculated by the Calculation Agent and shall be determined as the arithmetic
mean on the basis of the prime rates in The City of New York by the appropriate
number of substitute banks or trust companies organized and doing business under
the laws of the United States, or any State thereof, in each case having total
equity capital of at least U.S. $500 million and being subject to supervision or
examination by Federal or State authority, selected by the Calculation Agent to
quote such rate or rates.
 
     "Reuters Screen NYMF Page" means the display designated as Page "NYMF" on
the Reuters Monitor Money Rates Services (or such other page as may replace the
NYMF Page on that service for the purpose of displaying prime rates or base
lending rates of major United States banks).
 
     If in any month or two consecutive months the Prime Rate is not published
in H. 15(519) and the banks or trust companies selected as aforesaid are not
quoting as mentioned in the preceding paragraph, the "Prime Rate" for such
Interest Reset Period will be the same as the Prime Rate for the immediately
preceding
 
                                      S-12
<PAGE>   15
 
Interest Reset Period (or, if there was no such Interest Reset Period, the rate
of interest payable on the Prime Rate Notes for which the Prime Rate is being
determined shall be the Initial Interest Rate). If this failure continues over
three or more consecutive months, the Prime Rate for each succeeding Interest
Determination Date until the maturity or redemption or repayment of such Prime
Rate Notes or, if earlier, until this failure ceases, shall be LIBOR determined
as if such Prime Rate Notes were LIBOR Notes, and the Spread, if any, shall be
the number of basis points specified in the applicable Pricing Supplement as the
"Alternative Rate Event Spread."
 
Treasury Rate Notes
 
     Treasury Rate Notes will bear interest at the interest rate (calculated
with reference to the Treasury Rate and the Spread and/or Spread Multiplier, if
any, and subject to the Minimum Interest Rate and the Maximum Interest Rate, if
any) specified in each Treasury Rate Note and in the applicable Pricing
Supplement.
 
     Unless otherwise specified in the applicable Pricing Supplement, the
"Treasury Rate" means, with respect to any Interest Determination Date, the rate
for the auction held on such date of direct obligations of the United States
("Treasury Bills") having the Index Maturity designated in the applicable
Pricing Supplement, as published in H.15(519) under the heading "Treasury
Bills-auction average (investment)" or, if not so published by 3:00 p.m., New
York City time, on the Calculation Date pertaining to such Interest
Determination Date, the auction average rate on such Interest Determination Date
(expressed as a bond equivalent, on the basis of a year of 365 or 366 days, as
applicable, and applied on a daily basis) as otherwise announced by the United
States Department of the Treasury. In the event that the results of the auction
of Treasury Bills having the Index Maturity designated 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 on such
Interest Determination Date, then the Treasury Rate shall be calculated by the
Calculation Agent and shall be a yield to maturity (expressed as a bond
equivalent, on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) calculated using the arithmetic mean of the secondary
market bid rates, as of approximately 3:30 p.m., New York City time, on such
Interest Determination Date, of three leading primary United States government
securities dealers selected by the Calculation Agent for the issue of Treasury
Bills with a remaining maturity closest to the Index Maturity designated in the
applicable Pricing Supplement; provided, however, that if the dealers selected
as aforesaid by the Calculation Agent are not quoting bid rates as mentioned in
this sentence, the Treasury Rate for the applicable period will be the same as
the Treasury Rate for the immediately preceding Interest Reset Period (or, if
there was no such Interest Reset Period, the rate of interest payable on the
Treasury Rate Notes for which the Treasury Rate is being determined shall be the
Initial Interest Rate).
 
INDEXED NOTES
 
     The Notes may be issued, from time to time, as Notes of which the principal
amount payable on a date more than nine months from the date of original issue
(the "Stated Maturity") and/or on which the amount of interest payable on an
Interest Payment Date and/or any premium payable will be determined by reference
to currencies, currency units, commodity prices, financial or nonfinancial
indices or other factors (the "Indexed Notes"), as indicated in the applicable
Pricing Supplement. Holders of Indexed Notes may receive a principal amount at
maturity that is greater than or less than the face amount of such Notes
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 United States Federal tax considerations
will be described in the applicable Pricing Supplement.
 
EXTENSION OF MATURITY
 
     The Pricing Supplement relating to each Fixed Rate Note (other than an
Amortizing Note) will indicate whether the Company has the option to extend the
maturity of such Fixed Rate Note for one or more periods of one or more whole
years (each an "Extension Period") up to but not beyond the date (the "Final
Maturity
 
                                      S-13
<PAGE>   16
 
Date") set forth in such Pricing Supplement. If the Company has such option with
respect to any such Fixed Rate Note (an "Extendible Note"), the following
procedures will apply, unless modified as set forth in the applicable Pricing
Supplement.
 
     The Company may exercise such option with respect to an Extendible Note by
notifying the Paying Agent of such exercise at least 45 but not more than 60
days prior to the maturity date originally in effect with respect to such Note
(the "Original Maturity Date") or, if the maturity date of such Note has already
been extended, prior to the maturity date then in effect (an "Extended Maturity
Date"). At least 38 days prior to the Original Maturity Date or an Extended
Maturity Date, as the case may be (each, a "Maturity Date"), the Paying Agent
will mail to the holder of such Note a notice (the "Extension Notice") relating
to such Extension Period, by first-class mail, postage prepaid, setting forth
(a) the election of the Company to extend the maturity of such Note; (b) the new
Extended Maturity Date; (c) the interest rate applicable to the Extension
Period; and (d) the provisions, if any, for redemption during the Extension
Period, including the date or dates on which, the period or periods during which
and the price or prices at which such redemption may occur during the Extension
Period. Upon the mailing by the Paying Agent of an Extension Notice to the
holder of an Extendible Note, the Maturity of such Note shall be extended
automatically, and, except as modified by the Extension Notice and as described
in the next paragraph, such Note will have the same terms it had prior to the
mailing of such Extension Notice.
 
     Notwithstanding the foregoing, not later than 10:00 a.m., New York City
time, on the twentieth calendar day prior to the Maturity Date then in effect
for an Extendible Note (or, if such day is not a Business Day, not later than
10:00 a.m., New York City time, on the immediately succeeding Business Day), the
Company may, at its option, revoke the interest rate provided for in the
Extension Notice and establish a higher interest rate for the Extension Period
by causing the Paying Agent to send notice of such higher interest rate to the
holder of such Note by first-class mail, postage prepaid, or by such other means
as shall be agreed between the Company and the Paying Agent. Such notice shall
be irrevocable. All Extendible Notes with respect to which the Maturity Date is
extended in accordance with an Extension Notice will bear such higher interest
rate for the Extension Period, whether or not tendered for repayment.
 
     If the Company elects to extend the maturity of an Extendible Note, the
holder of such Note will have the option to require the Company to repay such
Note on the Maturity Date then in effect at a price equal to the principal
amount thereof plus any accrued and unpaid interest to such date. In order for
an Extendible Note to be repaid on such Maturity Date, the holder thereof must
follow the procedures set forth below under "Repayment at the Noteholders'
Option" for optional repayment, except that the period for delivery of such Note
or notification to the Paying Agent shall be at least 25 but not more than 35
days prior to the Maturity Date then in effect and except that a holder who has
tendered an Extendible Note for repayment pursuant to an Extension Notice may,
by written notice to the Paying Agent, revoke any such tender for repayment
until 3:00 p.m., New York City time, on the twentieth calendar day prior to the
Maturity Date then in effect (or, if such day is not a Business Day, until 3:00
p.m., New York City time, on the next succeeding Business Day).
 
BOOK-ENTRY SYSTEM
 
     Unless otherwise indicated in the applicable Pricing Supplement, upon
issuance, all Fixed Rate Book-Entry Notes having the same Issue Date, interest
rate, if any, amortization schedule, if any, maturity date and other terms, if
any, will be represented by one or more Global Securities, and all Floating Rate
Book-Entry Notes having the same Issue Date, Initial Interest Rate, Base Rate,
Interest Reset Period, Interest Payment Dates, Index Maturity, Spread and/or
Spread Multiplier, if any, Minimum Interest Rate, if any, Maximum Interest Rate,
if any, maturity date and other terms, if any, will be represented by one or
more Global Securities. Each Global Security representing Book-Entry Notes will
be deposited with, or on behalf of, The Depository Trust Company, New York, New
York (the "Depositary"), and registered in the name of a nominee of the
Depositary. Except under the circumstances described in the accompanying
Prospectus, Certificated Notes will not be exchangeable for Book-Entry Notes and
Book-Entry Notes will not be exchangeable for Certificated Notes. See
"Description of Debt Securities -- Global Securities" in the accompanying
Prospectus.
 
                                      S-14
<PAGE>   17
 
     The Depositary has advised the Company as follows: The Depositary is a
limited-purpose trust company organized under the Banking Law 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
Depositary was created to hold securities of its participating organizations
("Participants") and to facilitate the clearance and settlement of 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 Depositary's Participants include
securities brokers and dealers, banks, trust companies, clearing corporations,
and certain other organizations, some of whom (and for their representatives)
own the Depositary. Access to the Depositary 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.
 
     A further description of the Depositary's procedures with respect to Global
Securities representing Book-Entry Notes is set forth in the accompanying
Prospectus under "Description of Debt Securities -- Global Securities" in the
accompanying Prospectus.
 
OPTIONAL REDEMPTION
 
     Unless otherwise indicated in the applicable Pricing Supplement, Notes may
not be redeemed by the Company prior to maturity. If so specified in the
applicable Pricing Supplement, the Notes will be redeemable prior to maturity at
the option of the Company on the terms specified therein. Unless otherwise
indicated in the applicable Pricing Supplement, notice of redemption will be
provided by mailing a notice of such redemption to each holder by first-class
mail, postage prepaid, at least 30 days and not more than 60 days prior to the
date fixed for redemption to the respective address of each holder as that
address appears upon the books maintained by the Paying Agent.
 
REPAYMENT AT THE NOTEHOLDERS' OPTION
 
     Unless otherwise indicated in the applicable Pricing Supplement, Notes may
not be redeemed at the option of the holders thereof prior to maturity. If so
specified in the applicable Pricing Supplement, a Note will be repayable at the
option of the holder on a date or dates specified prior to its maturity date
and, unless otherwise specified in such Pricing Supplement, at a price equal to
100% of the principal amount thereof, together with accrued interest to the date
of repayment, unless such Notes were issued with original issue discount, in
which case the applicable Pricing Supplement will specify the amount payable
upon such repayment.
 
     Unless otherwise indicated in the applicable Pricing Supplement, in order
for such a Note to be repaid, the Paying Agent must receive at least 15 days but
not more than 30 days prior to the repayment date (i) the Note with the form
entitled "Option to Elect Repayment" on the reverse of the Note duly completed
or (ii) a telegram, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc. (the "NASD") or a commercial bank or trust company in the United States
setting forth the name of the holder of the Note, the principal amount of the
Note, the principal amount of the Note to be repaid, the certificate number or a
description of the tenor and terms of the Note, a statement that the option to
elect repayment is being exercised thereby and a guarantee that the Note to be
repaid, together with the duly completed form entitled "Option to Elect
Repayment" on the reverse of the Note, will be received by the Paying Agent not
later than the fifth Business Day after the date of such telegram, facsimile
transmission or letter, provided however, that such telegram, facsimile
transmission or letter shall only be effective if such Note and form duly
completed are received by the Paying Agent by such fifth Business Day. Except in
the case of Extendible Notes, and unless otherwise specified in the applicable
Pricing Supplement, exercise of the repayment option by the holder of a Note
will be irrevocable. The repayment option may be exercised by the holder of a
Note for less than the entire principal amount of the Note but, in that event,
the principal amount of the Note remaining outstanding after repayment must be
an authorized denomination.
 
                                      S-15
<PAGE>   18
 
     If a Note is represented by a Global Security, the Depositary's nominee
will be the holder of such Note and therefore will be the only entity that can
exercise a right to repayment. In order to ensure that the Depositary's nominee
will timely exercise a right to repayment with respect to a particular Note, the
beneficial owner of such Note must instruct the broker or other direct or
indirect Participant through which it holds an interest in such Note to notify
the Depositary of its desire to exercise a right to repayment. Different firms
have different cut-off times for accepting instructions from their customers
and, accordingly, each beneficial owner should consult the broker or other
direct or indirect Participant through which it holds an interest in a Note in
order to ascertain the cut-off time by which such an instruction must be given
in order for timely notice to be delivered to the Depositary.
 
REPURCHASE
 
     The Company may purchase Notes at any price in the open market or
otherwise. Notes so purchased by the Company may, at the discretion of the
Company, be held or resold or surrendered to the relevant Trustee for
cancelation.
 
                             FOREIGN CURRENCY RISKS
 
EXCHANGE RATES AND EXCHANGE CONTROLS
 
     Any investment in Notes that are denominated in, or the payment of which is
related to the value of, a Specified Currency other than U.S. dollars 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 rates of exchange between the U.S.
dollar and the various foreign currencies (or composite currencies) and the
possibility of the imposition or modification of exchange controls by either the
U.S. 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 U.S. dollars and certain foreign currencies have been highly
volatile and such volatility may be expected to continue in the future.
Fluctuations in any particular exchange rate that have occurred in the past are
not necessarily indicative, however, of fluctuations in such rate that may occur
during the term of any Note. Depreciation against the U.S. dollar of the
currency in which a Note is payable would result in a decrease in the effective
yield of such Note below its coupon rate and, in certain circumstances, could
result in a loss to the investor on a U.S. dollar basis. In addition, depending
on the specific terms of a Note denominated in a Specified Currency, changes in
exchange rates relating to any of the currencies involved may result in a
decrease in its effective yield and, in certain circumstances, could result in a
loss of all or a substantial portion of the principal of a Note to the investor.
 
     THIS PROSPECTUS SUPPLEMENT, THE ATTACHED PROSPECTUS AND ANY PRICING
SUPPLEMENT DO NOT DESCRIBE ALL THE RISKS OF AN INVESTMENT IN NOTES DENOMINATED
IN, OR THE PAYMENT OF WHICH IS RELATED TO THE VALUE OF, A FOREIGN CURRENCY OR A
COMPOSITE CURRENCY AND THE COMPANY DISCLAIMS ANY RESPONSIBILITY TO ADVISE
PROSPECTIVE PURCHASERS OF SUCH RISKS AS THEY EXIST AT THE DATE OF THIS
PROSPECTUS SUPPLEMENT OR AS SUCH RISKS MAY CHANGE FROM TIME TO TIME. PROSPECTIVE
INVESTORS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL ADVISORS AS TO THE RISKS
ENTAILED BY AN INVESTMENT IN NOTES DENOMINATED IN, OR THE PAYMENT OF WHICH IS
RELATED TO THE VALUE OF, SPECIFIED CURRENCIES OTHER THAN U.S. DOLLARS. SUCH
NOTES ARE NOT AN APPROPRIATE INVESTMENT FOR INVESTORS WHO ARE UNSOPHISTICATED
WITH RESPECT TO FOREIGN CURRENCY TRANSACTIONS.
 
     The information set forth in this Prospectus Supplement is directed to
prospective purchasers 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, holding or receipt of payments of principal of, premium, if
any, and interest on the Notes. Such persons should consult their own counsel
with regard to such matters.
 
                                      S-16

     Governments have imposed from time to time, and may in the future impose,
exchange controls which could affect exchange rates as well as the availability
of a specified foreign currency at the time of payment of principal of, premium,
if any, or interest on a Note. Even if there are no actual exchange controls, it
is possible that the Specified Currency for any particular Note not denominated
in U.S. dollars would not be available when payments on such Note are due. In
that event, the Company would make required payments in U.S. dollars on the
basis of the Market Exchange Rate on the date of such payment, or if such rate
of exchange is not then available, on the basis of the Market Exchange Rate as
of the most recent practicable date. See "Description of Notes -- Payment
Currency and Currency Exchange Information."
 
     With respect to any Note denominated in, or the payment of which is related
to the value of, a foreign currency or currency unit, the applicable Pricing
Supplement will include information with respect to applicable current exchange
controls, if any, and historic exchange rate information on such currency or
currency unit. The information contained therein shall not constitute a part of
this Prospectus Supplement and is 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.
 
GOVERNING LAW AND JUDGMENTS
 
     The Notes will be governed by and construed in accordance with the laws of
the State of New York. In the event an action based on Notes denominated in a
Specified Currency other than U.S. dollars were commenced in a Federal or State
court in the United States, it is likely that such court would grant judgment
relating to the Notes only in U.S. dollars. The date used to determine the rate
of conversion of a Specified Currency into U.S. dollars will depend upon various
factors, including which court renders the judgment. In the event of an action
based on Notes denominated in a Specified Currency other than U.S. dollars in a
state court in the State of New York, such court would be required to render
such judgment in the Specified Currency in which the Note is denominated, and
such judgment would be converted into U.S. dollars at the exchange rate
prevailing on the date of entry of the judgment.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a summary of the principal U.S. Federal tax consequences
resulting from the beneficial ownership of Notes by certain persons. This
summary does not purport to consider all the possible tax consequences of the
purchase, ownership or disposition of the Notes and is not intended to reflect
the individual tax position of any beneficial owner. It deals only with Notes
held as capital assets, whether issued in U.S. dollars or currencies or
composite currencies other than U.S. dollars ("Foreign Currency"). Moreover,
except as expressly indicated, it deals only with initial purchasers and does
not deal with beneficial owners with a special tax status or special tax
situations, such as dealers in securities or currencies, Notes (or Foreign
Currency) held as a hedge against currency risks or as part of a straddle with
other investments or as part of a "synthetic security" or other integrated
investment (including a "conversion transaction") comprised of a Note and one or
more other investments, or situations in which the functional currency of the
beneficial owner is not the U.S. dollar. Except to the extent discussed below
under "Non-United States Holders", this summary may not be applicable to
non-United States persons not subject to United States Federal income tax on
their worldwide income. The summary is based upon the United States Federal tax
laws and regulations as now in effect and as currently interpreted and does not
take into account possible changes in such tax laws or such interpretations,
which may be applied retroactively. It does not include any description of the
tax laws of any state, local or foreign governments that may be applicable to
the Notes or holders thereof. Persons considering the purchase of Notes should
consult their own tax advisors concerning the application of the United States
Federal tax laws to their particular situations as well as any consequences to
them under the laws of any other taxing jurisdiction.

UNITED STATES HOLDERS
 
Payments of Interest
 
     In general, interest on a Note, whether payable in U.S. dollars or a
Foreign Currency (other than certain payments on a Discount Note, as defined and
described below under "Original Issue Discount"), will be taxable to a
beneficial owner who or which is (i) a citizen or resident of the United States,
(ii) a corporation created or organized under the laws of the United States or
any State thereof (including the District of Columbia) or (iii) a person
otherwise subject to United States Federal income taxation on its worldwide
income (a "U.S. Holder") as ordinary income at the time it is received or
accrued, depending on the holder's method of accounting for tax purposes. If an
interest payment is denominated in or determined by reference to a Foreign
Currency, then special rules, described below under "Foreign Currency Notes",
apply.
 
Original Issue Discount
 
     The following discussion summarizes the United States Federal income tax
consequences to holders of Notes issued with original issue discount ("OID").
The basic rules for reporting OID are contained in the Internal Revenue Code of
1986, as amended (the "Code"). On February 2, 1994, the Treasury Department
published final regulations (the "OID Regulations"), which expand and illustrate
the rules provided by the Code. The OID Regulations are effective for debt
instruments issued on or after April 4, 1994, and the preamble to the OID
Regulations provides that a taxpayer generally may rely upon the OID Regulations
for debt instruments issued after December 21, 1992.
 
     Special rules apply to OID on a Discount Note that is denominated in
Foreign Currency. See "Foreign Currency Notes -- Foreign Currency Discount
Notes".
 
     General.  A Note will be treated as issued with OID (a "Discount Note") if
the excess of the Note's "stated redemption price at maturity" over its issue
price exceeds a de minimis amount (i.e., such excess is equal to or greater than
.25% of the "stated redemption price at maturity" multiplied by the number of
complete years to maturity). Generally, the issue price of a Note (or any Note
that is part of an issue of Notes) will be the first price at which a
substantial amount of Notes that are part of such issue of Notes are sold to the
public (excluding amounts sold to bond houses, brokers or similar persons or
organizations acting in the capacity of underwriters, placement agents or
wholesalers). Under the OID Regulations, the "stated redemption price at
maturity" of a Note is the sum of all payments provided by the Note that are not
payments of "qualified stated interest". A "qualified stated interest" payment
includes any stated interest payment on a Note that is unconditionally payable
at least annually at a single fixed rate (or at certain floating rates) that
appropriately takes into account the length of the interval between stated
interest payments. The applicable Pricing Supplement will state whether a
particular issue of Notes will constitute an issue of Discount Notes.
 
     In general, if the excess of a Note's stated redemption price at maturity
over its issue price is de minimis, then such excess constitutes "de minimis
OID". Under the OID Regulations, unless the election described below under
"Election to Treat All Interest as Original Issue Discount" is made, such a Note
will not be treated as issued with OID (in which case the following paragraphs
under "Original Issue Discount" will not apply) and a U.S. Holder of such a Note
will recognize capital gain with respect to such de minimis OID as stated
principal payments on the Note are made. The amount of such gain with respect to
each such payment will equal the product of the total amount of the Note's de
minimis OID and a fraction, the numerator of which is the amount of the
principal payment made and the denominator of which is the stated principal
amount of the Note.
 
     In certain cases, Notes that bear stated interest and are issued at par may
be deemed to bear OID for Federal income tax purposes, with the result that the
inclusion of interest in income for Federal income tax purposes may vary from
the actual cash payments of interest made on such Notes, generally accelerating
income for cash method taxpayers. Under the OID Regulations, a Note may be a
Discount Note where (i) a Floating Rate Note provides for a Maximum Interest
Rate or a Minimum Interest Rate that is reasonably expected as of the issue date
to cause the yield on the debt instrument to be significantly less, in the case
of a
 
                                      S-18
<PAGE>   21
 
maximum rate, or more, in the case of a minimum rate, than the expected yield
determined without the maximum or minimum rate, as the case may be; (ii) a
Floating Rate Note provides for significant front-loading or back-loading of
interest; (iii) a Note bears interest at certain combinations of floating or
fixed rates; or (iv) a Note provides for certain other kinds of contingent
payments. Notice will be given in the applicable Pricing Supplement when the
Company determines that a particular Note will be a Discount Note. Unless
specified in the applicable Pricing Supplement, Floating Rate Notes will not be
Discount Notes.
 
     The Code and the OID Regulations provide rules that require a U.S. Holder
of a Discount Note having a maturity of more than one year from its date of
issue to include OID in gross income before the receipt of cash attributable to
such income, without regard to the holder's method of accounting for tax
purposes. The amount of OID includible in gross income by a U.S. Holder of a
Discount Note is the sum of the "daily portions" of OID with respect to the
Discount Note for each day during the taxable year or portion of the taxable
year in which the U.S. Holder holds such Discount Note ("accrued OID"). The
daily portion is determined by allocating to each day in any "accrual period" a
pro rata portion of the OID allocable to that accrual period. Under the OID
Regulations, accrual periods with respect to a Note may be any set of periods
(which may be of varying lengths) selected by the U.S. Holder as long as (i) no
accrual period is longer than one year and (ii) each scheduled payment of
interest or principal on the Note occurs on the first day or final day of an
accrual period.
 
     The amount of OID allocable to an accrual period equals the excess of (a)
the product of the Discount Note's adjusted issue price at the beginning of the
accrual period and the Discount Note's yield to maturity (determined on the
basis of compounding at the close of each accrual period and properly adjusted
for the length of the accrual period) over (b) the sum of any payments of
qualified stated interest on the Discount Note allocable to the accrual period.
The "adjusted issue price" of a Discount Note at the beginning of the first
accrual period is the issue price and at the beginning of any accrual period
thereafter is (x) the sum of the issue price of such Discount Note, the accrued
OID for each prior accrual period (determined without regard to the amortization
of any acquisition premium or bond premium, which are discussed below), and the
amount of any qualified stated interest on the Note that has accrued prior to
the beginning of the accrual period but is not payable until a later date, less
(y) any prior payments on the Discount Note that were not qualified stated
interest payments. If a payment (other than a payment of qualified stated
interest) is made on the first day of an accrual period, then the adjusted issue
price at the beginning of such accrual period is reduced by the amount of the
payment. If a portion of the initial purchase price of a Note is attributable to
interest that accrued prior to the Note's issue date, the first stated interest
payment on the Note is to be made within one year of the Note's issue date and
such payment will equal or exceed the amount of pre-issuance accrued interest,
then the U.S. Holder may elect to decrease the issue price of the Note by the
amount of pre-issuance accrued interest, in which case a portion of the first
stated interest payment will be treated as a return of the excluded pre-issuance
accrued interest and not as an amount payable on the Note.
 
     The OID Regulations contain certain special rules that generally allow any
reasonable method to be used in determining the amount of OID allocable to a
short initial accrual period (if all other accrual periods are of equal length)
and require that the amount of OID allocable to the final accrual period equal
the excess of the amount payable at the maturity of the Note (other than any
payment of qualified stated interest) over the Note's adjusted issue price as of
the beginning of such final accrual period. In addition, if an interval between
payments of qualified stated interest on a Note contains more than one accrual
period, then the amount of qualified stated interest payable at the end of such
interval is allocated pro rata (on the basis of their relative lengths) between
the accrual periods contained in the interval.
 
     U.S. Holders of Discount Notes generally will have to include in income
increasingly greater amounts of OID over the life of the Note.
 
     Acquisition Premium.  A U.S. Holder that purchases a Note at its original
issuance for an amount in excess of its issue price but less than its stated
redemption price at maturity (any such excess being "acquisition premium"), and
that does not make the election described below under "Original Issue Discount
- -- Election To Treat All Interest as Original Issue Discount", is permitted to
reduce the daily portions of OID by a fraction, the numerator of which is the
excess of the U.S. Holder's purchase price for the Note over the
 
                                      S-19
<PAGE>   22
 
issue price for the Note, and the denominator of which is the excess of the sum
of all amounts payable on the Note after the purchase date, other than payments
of qualified stated interest, over the Note's issue price. Alternatively, a U.S.
Holder may elect to compute OID accruals as described under "Original Issue
Discount -- General" above, treating the U.S. Holder's purchase price as the
issue price.
 
     Optional Redemption.  If the Company has an option to redeem a Note, or the
Holder has an option to cause a Note to be repurchased, prior to the Note's
stated maturity, such option will be presumed to be exercised if, by utilizing
any date on which such Note may be redeemed or repurchased as the maturity date
and the amount payable on such date in accordance with the terms of such Note
(the "redemption price") as the stated redemption price at maturity, the yield
on the Note would be (i) in the case of an option of the Company, lower than its
yield to stated maturity, or (ii) in the case of an option of the Holder, higher
than its yield to stated maturity. If such option is not in fact exercised when
presumed to be exercised, the Note would be treated solely for OID purposes as
if it were redeemed or repurchased, and a new Note were issued, on the presumed
exercise date for an amount equal to the Note's adjusted issue price on that
date.
 
     Short-Term Notes.  Under the Code, special rules apply with respect to OID
on Notes that mature one year or less from the date of their issuance
("Short-Term Notes"). In general, an individual or other cash basis U.S. Holder
of a Short-Term Note is not required to include OID in income as it accrues for
United States Federal income tax purposes unless it elects to do so. Accrual
basis U.S. Holders and certain other U.S. Holders, including banks, regulated
investment companies, dealers in securities and cash basis U.S. Holders who so
elect, are required to include OID on Short-Term Notes as it accrues on either a
straight-line basis or under the constant yield method (based on daily
compounding), at the election of the U.S. Holder. In the case of a U.S. Holder
not required and not electing to include OID in income currently, any gain
realized on the sale or retirement of the Short-Term Note will be ordinary
income to the extent of the OID accrued on a straight-line basis (unless an
election is made to accrue the original issue discount under the constant yield
method) through the date of sale or retirement. U.S. Holders who are not
required and do not elect to include OID on Short-Term Notes in income as it
accrues will be required to defer deductions for interest on borrowings
allocable to Short-Term Notes in an amount not exceeding the deferred income
until the deferred income is realized.
 
     Any U.S. Holder of a Short-Term Note can elect to apply the rules in the
preceding paragraph taking into account the amount of "acquisition discount", if
any, with respect to the Note (rather than the OID with respect to such Note).
Acquisition discount is the excess of the stated redemption price at maturity of
the Short-Term Note over the U.S. Holder's purchase price. Acquisition discount
will be treated as accruing on a ratable basis or, at the election of the
holder, on a constant-yield basis. However, any payment on a Short-Term Note,
whether denominated as principal or interest, will be treated as a taxable
payment of accrued OID, to the extent that OID has accrued at the time of
payment.
 
     For purposes of determining the amount of OID subject to these rules, the
OID Regulations provide that no interest payments on a Short-Term Note are
qualified stated interest, but instead such interest payments are included in
the Short-Term Note's stated redemption price at maturity.
 
Notes Purchased at a Premium
 
     Under the Code, a U.S. Holder that purchases a Note for an amount in excess
of its principal amount will not be subject to the OID rules and may elect to
treat such excess as "amortizable bond premium", in which case the amount
required to be qualified stated included in the U.S. Holder's income each year
with respect to interest on the Note will be reduced by the amount of
amortizable bond premium allocable (based on the Note's yield to maturity) to
such year. Any election to amortize bond premium shall apply to all bonds (other
than bonds the interest on which is excludible from gross income) held by the
U.S. Holder at the beginning of the first taxable year to which the election
applies or thereafter acquired by the U.S. Holder, and is irrevocable without
the consent of the Internal Revenue Service (the "IRS"). See also "Original
Issue Discount -- Election to Treat All Interest as Original Issue Discount".
 
                                      S-20
<PAGE>   23
 
Notes Purchased at a Market Discount
 
     A Note, other than a Short-Term Note, will be treated as issued at a market
discount (a "Market Discount Note") if the amount for which a U.S. Holder
purchased the Note is less than the Note's issue price, subject to a de minimis
rule similar to the rule relating to de minimis OID described under "Original
Issue Discount -- General".
 
     In general, any gain recognized on the maturity or disposition of a Market
Discount Note will be treated as ordinary income to the extent that such gain
does not exceed the accrued market discount on such Note. Alternatively, a U.S.
Holder of a Market Discount Note may elect to include market discount in income
currently over the life of the Note. Such an election applies to all debt
instruments with market discount acquired by the electing U.S. Holder on or
after the first day of the first taxable year to which the election applies and
may not be revoked without the consent of the IRS.
 
     Market discount accrues on a straight-line basis unless the U.S. Holder
elects to accrue such market discount on a constant yield to maturity basis.
Such an election shall apply only to the Note with respect to which it is made
and may not be revoked. A U.S. Holder of a Market Discount Note who does not
elect to include market discount in income currently generally will be required
to defer deductions for interest on borrowings allocable to such Note in an
amount not exceeding the accrued market discount on such Note until the maturity
or disposition of such Note.
 
     The market discount rules do not apply to a Short-Term Note.
 
     Election To Treat All Interest as Original Issue Discount.  Any U.S. Holder
that holds a Note issued after April 4, 1994, may elect to include in gross
income all interest that accrues on a Note using the constant yield method
described above under the heading "Original Issue Discount -- General," with the
modifications described below. For purposes of this election, interest includes
stated interest, OID, de minimis OID, market discount (described above under
"Notes Purchased at a Market Discount"), acquisition discount, de minimis market
discount and unstated interest, as adjusted by any amortizable bond premium
(described above under "Notes Purchased at a Premium") or acquisition premium.
 
     In applying the constant yield method to a Note with respect to which this
election has been made, the issue price of the Note will equal the electing U.S.
Holder's adjusted basis in the Note immediately after its acquisition, the issue
date of the Note will be the date of its acquisition by the electing U.S.
Holder, and no payments on the Note will be treated as payments of qualified
stated interest. This election will generally apply only to the Note with
respect to which it is made and may not be revoked without the consent of the
IRS. If this election is made with respect to a Note with amortizable bond
premium, then the electing U.S. Holder will be deemed to have elected to apply
amortizable bond premium against interest with respect to all debt instruments
with amortizable bond premium (other than debt instruments the interest on which
is excludible from gross income) held by such electing U.S. Holder as of the
beginning of the taxable year in which the Note with respect to which the
election is made is acquired or thereafter acquired. The deemed election with
respect to amortizable bond premium may not be revoked without the consent of
the IRS.
 
     If the election described above to apply the constant-yield method to all
interest on a Note is made with respect to a Market Discount Note, as defined
above, then the electing U.S. Holder will be treated as having made the election
discussed above under "Notes Purchased at a Market Discount" to include market
discount in income currently over the life of all debt instruments held or
thereafter acquired by such U.S. Holder.
 
Purchase, Sale and Retirement of the Notes
 
     General.  A U.S. Holder's tax basis in a Note will generally be its U.S.
dollar cost (which, in the case of a Note purchased with a foreign currency,
will be the U.S. dollar value of the purchase price on the date of purchase),
increased by the amount of any OID or market discount (or acquisition discount,
in the case of a Short-Term Note) included in the U.S. Holder's income with
respect to the Note and the amount, if any, of income attributable to de minimis
OID included in the U.S. Holder's income with respect to the Note, and reduced
by the sum of (i) the amount of any payments that are not qualified stated
interest payments, and (ii) the amount of any amortizable bond premium applied
to reduce interest on the Note. A U.S. Holder
 
                                      S-21
<PAGE>   24
 
generally will recognize gain or loss on the sale or retirement of a Note equal
to the difference between the amount realized on the sale or retirement and the
tax basis of the Note. The amount realized on a sale or retirement for an amount
in foreign currency will be the U.S. dollar value of such amount on the date of
sale or retirement. Except to the extent described above under "Original Issue
Discount -- Short Term Notes" or "Market Discount" or below under "Foreign
Currency Notes", and except to the extent attributable to accrued but unpaid
interest, gain or loss recognized on the sale or retirement of a Note will be
capital gain or loss and will be long-term capital gain or loss if the Note was
held for more than one year.
 
Foreign Currency Notes
 
     Interest Payments.  If an interest payment is denominated in or determined
by reference to a Foreign Currency, the amount of income recognized by a cash
basis U.S. Holder will be the U.S. dollar value of the interest payment, based
on the exchange rate in effect on the date of receipt, regardless of whether the
payment is in fact converted into U.S. dollars. Accrual basis U.S. Holders may
determine the amount of income recognized with respect to such interest payments
in accordance with either of two methods. Under the first method, the amount of
income recognized will be based on the average exchange rate in effect during
the interest accrual period (or, with respect to an accrual period that spans
two taxable years, the partial period within the taxable year). Upon receipt of
an interest payment (including a payment attributable to accrued but unpaid
interest upon the sale or retirement of a Note) determined by reference to a
Foreign Currency, an accrual basis U.S. Holder will recognize ordinary income or
loss measured by the difference between such average exchange rate and the
exchange rate in effect on the date of receipt, regardless of whether the
payment is in fact converted into U.S. dollars. Under the second method, an
accrual basis U.S. Holder may elect to translate interest income into U.S.
dollars at the spot exchange rate in effect on the last day of the accrual
period or, in the case of an accrual period that spans two taxable years, at the
exchange rate in effect on the last day of the partial period within the taxable
year. Additionally, if a payment of interest is actually received within 5
business days of the last day of the accrual period or taxable year, an accrual
basis U.S. Holder applying the second method may instead translate such accrued
interest into U.S. dollars at the spot exchange rate in effect on the day of
actual receipt (in which case no exchange gain or loss will result). Any
election to apply the second method will apply to all debt instruments held by
the U.S. Holder at the beginning of the first taxable year to which the election
applies or thereafter acquired by the U.S. Holder, and will be irrevocable
without the consent of the IRS.
 
     Exchange of Amounts in Other than U.S. Dollars.  Foreign Currency received
as interest on a Note or on the sale or retirement of a Note will have a tax
basis equal to its U.S. dollar value at the time such interest is received or at
the time of such sale or retirement, as the case may be. Foreign Currency that
is purchased will generally have a tax basis equal to the U.S. dollar value of
the Foreign Currency on the date of purchase. Any gain or loss recognized on a
sale or other disposition of a Foreign Currency (including its use to purchase
Notes or upon exchange for U.S. dollars) will be ordinary income or loss.
 
     Foreign Currency Discount Notes.  OID for any accrual period on a Discount
Note that is denominated in a Foreign Currency will be determined in the Foreign
Currency and then translated into U.S. dollars in the same manner as stated
interest accrued by an accrual basis U.S. Holder. Upon receipt of an amount
attributable to original issue discount (whether in connection with a payment of
interest or the sale or retirement of a Note), a U.S. Holder may recognize
ordinary income or loss.
 
     Amortizable Bond Premium.  In the case of a Note that is denominated in a
Foreign Currency, bond premium will be computed in units of Foreign Currency,
and amortizable bond premium will reduce interest income in units of the Foreign
Currency. At the time amortized bond premium offsets interest income, a U.S.
Holder may realize ordinary income or loss, measured by the difference between
exchange rates at that time and at the time of the acquisition of the Notes.
 
     Exchange Gain or Loss.  Gain or loss recognized by a U.S. Holder on the
sale or retirement of a Note that is attributable to changes in exchange rates
will be treated as ordinary income or loss. However, exchange gain or loss is
taken into account only to the extent of total gain or loss realized on the
transaction.

Indexed Notes
 
     The applicable Pricing Supplement will contain a discussion of any special
United States Federal income tax rules with respect to Indexed Notes.
 
NON-UNITED STATES HOLDERS
 
     Subject to the discussion of backup withholding below, payments of
principal (and premium, if any) and interest, including OID, by the Company or
any agent of the Company (acting in its capacity as such) to any holder of a
Note that is not a United States person (a "Non-U.S. Holder") will not be
subject to U.S. Federal withholding tax; provided, however, that in the case of
interest, including OID, (i) such holder does not actually or constructively own
10% or more of the total combined voting power of all classes of stock of the
Company entitled to vote, (ii) such holder is not a controlled foreign
corporation for U.S. tax purposes that is related to the Company (directly or
indirectly) through stock ownership and (iii) either (A) the beneficial owner of
the Note 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 (B) a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business (a
"financial institution") and holds the Note certifies to the Company or its
agent under penalties of perjury that such statement has been received from the
beneficial owner by it or by another financial institution and furnishes the
payor with a copy thereof.
 
     If a Non-U.S. Holder is engaged in a trade or business in the United States
and interest, including OID, on the Note is effectively connected with the
conduct of such trade or business, such holder, although exempt from the
withholding tax discussed in the preceding paragraph, may be subject to U.S.
Federal income tax on such interest, and OID, in the same manner as if it were a
U.S. Holder. In addition, if such a holder is a foreign corporation, it 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. For
purposes of the branch profits tax, interest (including OID) on a Note will be
included in the earnings and profits of such holder if such interest (or OID) is
effectively connected with the conduct by such holder of a trade or business in
the United States. In lieu of the certificate described in the preceding
paragraph, such a holder must provide the payor with a properly executed IRS
Form 4224 to claim an exemption from U.S. Federal withholding tax.
 
     Any capital gain, market discount or exchange gain realized on the sale,
exchange, retirement or other disposition of a Note by a Non-U.S. Holder will
not be subject to U.S. Federal income or withholding taxes if (i) such gain is
not effectively connected with a U.S. trade or business of the holder and (ii)
in the case of an individual, such holder (A) is not present in the United
States for 183 days or more in the taxable year of the sale, exchange,
retirement or other disposition or (B) does not have a tax home (as defined in
Section 911(d)(3) of the Code) in the United States in the taxable year of the
sale, exchange, retirement or other disposition and the gain is not attributable
to an office or other fixed place of business maintained by such individual in
the United States.
 
     Notes held by an individual who is neither a citizen nor a resident of the
United States for U.S. Federal tax purposes at the time of such individual's
death will not be subject to U.S. Federal estate tax, provided that the income
from such Notes was not or would not have been effectively connected with a U.S.
trade or business of such individual and that such individual qualified for the
exemption from U.S. Federal withholding tax (without regard to the certification
requirements) described above.
 
     PURCHASERS OF NOTES WHO ARE NON-U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX
ADVISORS WITH RESPECT TO THE POSSIBLE APPLICABILITY OF UNITED STATES WITHHOLDING
AND OTHER TAXES UPON INCOME REALIZED IN RESPECT OF THE NOTES.

INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     For each calendar year in which the Notes are outstanding, each Participant
or indirect Participant holding an interest in a Note on behalf of a beneficial
owner of a Note and each paying agent making payments in respect of a Note will
generally be required to provide the IRS with certain information, including
such beneficial owner's name, address and taxpayer identification number (either
such beneficial owner's Social Security number or its employer identification
number, as the case may be), and the aggregate amount of interest and principal
paid to such beneficial owner during the calendar year. These reporting
requirements, however, do not apply with respect to certain beneficial owners
who establish their eligibility for an exemption, including corporations,
securities broker-dealers, other financial institutions, tax-exempt
organizations, qualified pension and profit sharing trusts, individual
retirement accounts and Non-U.S. persons that hold either (i) Notes directly and
receive payments thereon outside the United States or (ii) Notes indirectly
through Euroclear or Cedel, as the case may be.
 
     In the event that a beneficial owner of a Note fails to establish its
exemption from such information reporting requirements or is subject to the
reporting requirements described above and fails to supply its correct taxpayer
identification number in the manner required by applicable law, or underreports
its tax liability, as the case may be, the Participant or indirect Participant
holding such interest on behalf of such beneficial owner or paying agent making
payments in respect of a Note may be required to "backup" withhold a tax equal
to 31% of each payment of interest and principal with respect to Notes. This
backup withholding tax is not an additional tax and may be credited against the
beneficial owner's United States Federal income tax liability if the required
information is furnished to the IRS.
 
                              PLAN OF DISTRIBUTION
 
     The Notes are being offered on a continuing basis by the Company through
the Agents, each of which has agreed to use its best efforts to solicit offers
to purchase Notes. The Company will have the sole right to accept offers to
purchase Notes and may reject any offer to purchase Notes in whole or in part.
An Agent will have the right to reject any offer to purchase Notes solicited by
it in whole or in part. Payment of the purchase price of the Notes will be
required to be made in immediately available funds. The Company will pay an
Agent, in connection with sales of Notes resulting from a solicitation made or
an offer to purchase received by such Agent, a commission, initially ranging
from .125% to .750% of the principal amount of Notes to be sold or such other
commissions as may be negotiated from time to time. The Company also reserves
the right to sell Notes directly to investors on its behalf in those
jurisdictions where it is authorized to do so.
 
     The Company may also sell Notes to an Agent as principal for its own
account at discounts to be agreed upon at the time of sale. Such Notes may be
resold to investors and other purchasers at prevailing market prices, or prices
related thereto at the time of such resale or otherwise, as determined by the
Agent. In addition, the Agents may offer the Notes they have purchased as
principal to other dealers. The Agents may sell Notes to any dealer at a
discount and, unless otherwise specified in the applicable Pricing Supplement,
such discount allowed to any dealer will not be in excess of the discount to be
received by such Agent from the Company. After the initial public offering of
Notes to be resold to investors and other purchasers on a fixed public offering
price basis, the public offering price, concession and discount may be changed.
 
     An Agent may be deemed to be an "underwriter" within the meaning of the
Securities Act of 1933, as amended (the "Securities Act"). The Company and the
Agents have agreed to indemnify each other against certain liabilities,
including liabilities under the Securities Act, or to contribute to payments
made in respect thereof. The Company has also agreed to reimburse the Agents for
certain expenses, including the reasonable fees and expenses of counsel.
 
     The Company does not intend to apply for the listing of the Notes on a
national securities exchange, but has been advised by the Agents that the Agents
intend to make a market in the Notes, as permitted by applicable laws and
regulations. The Agents are not obligated to do so, however, and the Agents may
discontinue making a market at any time without notice. No assurance can be
given as to the liquidity of any trading market for the Notes.

                                  THE COMPANY
 
     Olin Corporation, a Virginia corporation incorporated in 1892, is a
manufacturer of chemicals, metals, and ammunition and defense-related products
which it markets to commercial and governmental customers. Results for the
Company are reported in three operating segments: chemicals, metals, and defense
and ammunition. The Company has recognized brand names in each of these
segments, including Olin pool chemicals sold under the brand names HTH(R),
Pace(R) and SUN(R), metal products sold under the brand name Olin(R) Brass and
sporting ammunition sold under the brand names Winchester(R) and Super-X(R).
 
     References to the Company in this section include the Company and its
subsidiaries and affiliates. Olin's principal executive offices are located at
120 Long Ridge Road, Stamford, Connecticut 06904, telephone (203) 356-2000.
 
CHEMICALS
 
     In its largest segment, the Company manufactures and markets three major
product lines: chlor-alkali, urethanes and pool chemicals. In addition, it
produces a number of other chemical products described below.
 
     Chlor-Alkali.  The Company is a leading producer of chlorine and caustic
soda in the southeastern United States, with facilities at McIntosh, Alabama,
Charleston, Tennessee, and Augusta, Georgia. In addition, Niachlor, a
partnership formed between the Company and E.I. duPont de Nemours & Company,
produces chlorine and caustic soda at a Niagara Falls, New York facility.
 
     Chlorine and caustic soda are co-products of the electrolysis of salt.
Chlorine is used as a bleaching agent in pulp and paper manufacturing and as a
raw material in the production of polyvinyl chloride. It is also used in the
manufacture of bleach and in water purification and in general inorganic and
organic chemical manufacturing. Caustic soda is used in petroleum refining and
in the manufacturing of pulp and paper, aluminum, detergents, soap and in a
variety of other organic and inorganic chemical products.
 
     While the Company has historically marketed chlorine to pulp and paper
manufacturers in the southeastern United States, environmental concerns have
resulted in the decreased usage of chlorine in pulp bleaching. As a result, the
Company has shifted its chlorine business mix to other markets, including
manufacturers of ethylene dichloride and vinyl chloride monomer, as well as
other industrial customers. Approximately 30% of the Company's chlorine is used
captively for the manufacture of pool chemicals, toluene di-isocyanate ("TDI")
and other uses.
 
     Urethanes.  The Company has one of the largest production capacities in the
United States for TDI, a key component in the production of urethane foam which
is used in products such as automotive seating, furniture, mattresses and
padding. The Company sells TDI and an array of polyether polyols to intermediate
and final manufacturers of urethane foam products. The Company's polyols are
used to produce urethane products that are known as flexible urethanes, rigid
urethanes, and non-foam urethanes.
 
     In addition, the Company is a supplier of specialty polyols used in
adhesives, coatings, elastomers and sealants. These products are sold to
intermediate and end use manufacturers.
 
     Pool Chemicals.  The Company manufactures or markets a wide array of
swimming pool chemicals and accessory products. It has three widely recognized
brand names in the U.S. pool chemicals industry: HTH(R), Pace(R), and SUN(R).
The Company sells its pool chemical products to mass merchandisers, pool
professionals, distributors and pool chemical repackers. In addition, the
Company participates in the worldwide pool chemicals market through joint
ventures in Brazil and South Africa. Pool chemicals are manufactured using
chlorine and caustic soda, which can be directly sourced from the Company's own
production. The Company has the largest production capacity for calcium
hypochlorite in the United States, much of which is sold under the HTH(R) brand
name. The pool business assets acquired from FMC Corporation in 1985, which
include one of the Company's two isocyanurate manufacturing facilities, its
packaging facility and the Sun(R) trademark, are subject to a final Federal
Trade Commission divestiture order.
 
     Other Chemical Products.  The Company manufactures a large number of
additional chemical products which are sold to intermediate and end use
manufacturers, such as zinc Omadine(R) additive used in anti-
 
                                        3
<PAGE>   31
 
dandruff shampoos; sulfuric acid used in petroleum refining and in manufacturing
agricultural chemicals; hydrazine solutions used as an intermediate in plastics
manufacturing and agricultural chemicals; hydrazine-based rocket propellants;
Reductone(R) brand sodium hydrosulfite used in paper, textile and clay
bleaching; and surfactants and fluids used in industrial and institutional
detergents and hydraulic fluids.
 
     Olin recently constructed an aliphatic di-isocyanate ("ADI") plant at Lake
Charles, Louisiana. The products manufactured at the ADI plant are used by
manufacturers of products such as automotive topcoats, premium paints and marine
and metal appliance finishes.
 
     The Company, through Olin Hunt Specialty Products, Inc., a wholly-owned
subsidiary, and OCG Microelectronic Materials ("OCG"), affiliated joint venture
companies owned by the Company and CIBA-GEIGY Limited, develops, manufactures
and markets image-forming and other specialty electronic chemicals. In
particular, OCG produces and markets worldwide photoresist and polyimide
products, both of which are basic materials for manufacturing semiconductors.
 
METALS
 
     The Company is a leading brass and copper alloy manufacturer in the United
States and rerolls and forms other metals. It is an active participant in the
worldwide market for these products, selling directly to large volume customers
and through distributors. The Company, through sales of its Posit-Bond(R) clad
metal, produced by a unique cladding process, is a supplier of metal to the U.S.
Mint. The Company also sells various alloys to foreign governments for coinage
purposes.
 
     While the end use markets for the Company's metal products vary from year
to year, principal markets include automotive (for connectors and radiators);
electronics (for lead frames, connectors and wiring); ammunition; coinage
metals; and other applications such as builder's hardware and plumbing supplies
and seamless and welded tube (for utility condensers and industrial heat
exchangers). The Company uses a portion of its ammunition cartridge cup
production captively in its Winchester(R) sporting ammunition and also sells
this brass product to other ammunition makers.
 
     In 1988, the Company acquired the former Bridgeport Brass Corporation of
Indianapolis, with primary manufacturing operations in Indianapolis, Indiana and
Bryan, Ohio, which significantly increased the Company's brass manufacturing
capacity.
 
     In 1991, the Company acquired A. J. Oster Company ("Oster"), a distributor
of copper and copper-based alloy products, steel products, aluminum strip and
aluminum foil. Oster has a network of metal service centers located in several
states and Puerto Rico.
 
     The Company has a joint venture with Yamaha of Japan, which sells high
performance alloys into the Far East market. The joint venture's local
manufacturing presence has enabled Olin Brass to participate in the Japanese
market for such products.
 
DEFENSE AND AMMUNITION
 
     The Company produces small, medium and large caliber ammunition for sale to
commercial and military customers. The Company's Winchester Division is a
leading U.S. producer of ammunition for recreational shooters, hunters, law
enforcement agencies and the U.S. Armed Forces. The Company's Ordnance Division
provides medium and large caliber ammunition to governmental customers. In
addition, the Company's Aerospace Division provides advanced technology products
to the defense and aerospace industries.
 
     Winchester.  The Winchester(R) brand name is widely recognized. The
Company's product line includes all major sizes of shotgun shells and rimfire
and centerfire ammunition for pistols and rifles. These products are sold to
mass merchandisers, distributors and the U.S. Government. This ammunition is
manufactured in East Alton, Illinois. Powder for Winchester(R) ammunition is
sourced from the Company's Ball Powder(R) propellant plant in St. Marks,
Florida.
 
                                        4
<PAGE>   32
 
     In 1993, the Company completed its eighth year of managing the Lake City
Army Ammunition Plant at Independence, Missouri. This government-owned,
contractor-operated ("GOCO") facility is the largest small caliber ammunition
facility in the United States.
 
     Ordnance.  The Company's Ordnance Division provides medium (20 and 30
millimeter) and large (105 and 120 millimeter) caliber ammunition to the United
States and certain foreign governments. Olin Ordnance is a major supplier of
ammunition for the Abrams M1A1 tank which was utilized in the Persian Gulf War.
 
     This division utilizes its project and program management capabilities as
both a prime and subcontractor on contracts in which other defense suppliers
participate. The Company seeks to exploit these capabilities to acquire
additional GOCO work and to bid on other project management work. The Company
believes there are also opportunities in the area of weapons demilitarization.
 
     Aerospace.  The Company's Aerospace Division is comprised of two
subsidiaries: Olin Aerospace Company ("OAC") and Physics International Company.
Customers for these subsidiaries include satellite, aircraft and missile
contractors, other defense/aerospace subsystems and systems contractors, the
National Aeronautics and Space Administration and other government research and
development agencies and laboratories.
 
     OAC is recognized as a major manufacturer of small rocket motors and
control thrusters used in satellites and other spacecraft such as Voyager II and
Magellan. It has been a leader in this technology for more than 20 years and
more recently has become a leader in advanced electric propulsion technology and
systems for satellites and spacecraft. OAC also manufactures inflators used in
various flotation devices, military munitions dispensing systems and aircraft
escape systems, as well as low voltage power conditioning and controlling
devices, digital test equipment and airborne electronic products.
 
     Physics International Company's pulsed power systems are used in nuclear
radiation simulators and other electromagnetic applications. In addition, it
designs, tests and manufactures advanced, high performance anti-armor warhead
systems.
 
                                USE OF PROCEEDS
 
     Unless otherwise set forth in the applicable Prospectus Supplement, the net
proceeds from the sale of the Offered Securities will be used for general
corporate purposes, which may include additions to working capital, capital
expenditures, stock repurchases, repayment of indebtedness and acquisitions.

<PAGE>   33
 
     In 1993, the Company recorded an after-tax charge of $132 million for
personnel reductions, business restructurings involving consolidations and
re-alignments within divisions, costs at sites of discontinued businesses,
future environmental liabilities and other charges. In 1991, the Company
recorded an after-tax charge of $80 million to cover losses on the disposition
and write-down of certain businesses and costs of personnel reductions.
 
     For purposes of computing these consolidated ratios, earnings represent
income before income taxes with certain adjustments, primarily for capitalized
interest, plus fixed charges. Fixed charges consist of interest expense
(including capitalized interest), amortization of debt discount and expense, and
the estimated interest factor reflected in rental expense. For the consolidated
ratio of earnings to combined fixed charges and preferred stock dividends, fixed
charges are then aggregated with preferred stock dividend requirements on the
outstanding preferred stock.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The following description of the terms of the Debt Securities 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 apply to the Debt Securities so offered will be described
in the Prospectus Supplement relating to such Debt Securities. Accordingly, for
a description of the terms of a particular issue of Debt Securities, reference
must be made to both the Prospectus Supplement relating thereto and to the
following description.
 
     Senior Securities were and may be issued under an Indenture dated as of
June 15, 1992, as supplemented ("Senior Indenture"), between Olin and Chemical
Bank. Subordinated Securities may be issued under an Indenture ("Subordinated
Indenture") between Olin and a commercial bank to be selected (collectively, the
Senior Indenture and the Subordinated Indenture are referred to as the
"Indentures"). Copies of the Indentures have been filed as exhibits to the
Registration Statement filed with the Commission. Chemical Bank will serve as
Trustee for series of Senior Securities and a commercial bank to be selected
will serve as Trustee for any series of Subordinated Securities which may be
issued. The following summaries of certain provisions of the Indentures do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all provisions of the Indentures including the definition
therein of certain terms.
 
GENERAL
 
     The Indentures do not limit the aggregate principal amount of Debt
Securities which may be issued thereunder. The Debt Securities may be issued in
one or more series as may be authorized from time to time by Olin. Reference is
made to the applicable Prospectus Supplement for the following terms of the Debt
Securities: (i) the designation, aggregate principal amount and authorized
denominations of the Debt Securities; (ii) the percentage of their principal
amount at which such Debt Securities will be issued; (iii) the date on which the
Debt Securities will mature; (iv) the rate or rates (which may be fixed or
variable) per annum, if any, or the method of determining such rate or rates, at
which the Debt Securities will bear interest; (v) the times at which any such
interest will be payable; (vi) the currency or currencies or units of two or
more currencies in which the Debt Securities are denominated and principal and
interest may be payable, and for which the Debt Securities may be purchased,
which may be in United States dollars, a foreign currency or currencies or units
of two or more foreign currencies; (vii) whether such Debt Securities are to be
Senior Securities or Subordinated Securities; (viii) any redemption or sinking
fund terms or certain other specific terms; (ix) any Event of Default or
covenant with respect to the Debt Securities of a particular series, if not set
forth herein, and (x) any other terms of such series (which terms shall not be
inconsistent with the provisions of the Subordinated Indenture or the Senior
Indenture, as the case may be). Unless otherwise indicated in the applicable
Prospectus Supplement, principal, premium, if any, and interest, if any, will be
payable and the Debt Securities will be transferable at the corporate trust
office of the respective Trustee, provided that payment of interest may be made
at the option of Olin by check mailed to the address of the person entitled
thereto as it appears in the respective Debt Securities register.
 
                                        6
<PAGE>   34
 
     The Debt Securities will be unsecured. Senior Securities will rank on a
parity with all other unsecured and unsubordinated indebtedness of Olin.
Subordinated Securities will be subordinated to certain present and future
superior indebtedness of Olin. See "Subordination of Subordinated Securities"
below.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Debt Securities will be issued only in fully registered form without coupons and
in denominations of $1,000 or any integral multiple thereof. No service charge
will be made for any transfer or exchange of such Debt Securities, but Olin may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.
 
     Special federal income tax and other considerations relating to Debt
Securities denominated in foreign currencies or units of two or more foreign
currencies will be described in the applicable Prospectus Supplement.
 
     Debt Securities may be issued as discounted Debt Securities (bearing no
interest or interest at a rate which at the time of issuance is below market
rates) to be sold at a substantial discount below their stated principal amount.
Federal income tax consequences and other special considerations applicable to
any such discounted Debt Securities will be described in the Prospectus
Supplement relating thereto.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
covenants contained in the Indentures and the Debt Securities will not afford
holders of Debt Securities protection in the event of a highly leveraged
transaction involving the Company.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series issued under the Indentures may be issued
in whole or in part in the form of one or more global securities (the "Global
Securities") that will be deposited with, or on behalf of, a depositary (the
"Depositary") identified in the Prospectus Supplement relating to such series.
Global Securities may be issued only in fully registered form and in either
temporary or permanent form. Unless and until it is exchanged in whole or in
part for the individual Debt Securities represented thereby, a Global Security
may not be transferred except as a whole by the Depositary for such Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by the Depositary or
any nominee to a successor Depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. Olin anticipates that the following provisions will generally apply
to depositary arrangements.
 
     Upon the issuance of a Global Security, the Depositary for such Global
Security or its nominee will credit, on its book-entry registration and transfer
system, the respective principal amounts of the individual Debt Securities
represented by such Global Security to the accounts of persons that have
accounts with such Depositary. Such accounts shall be designated by the dealers,
underwriters or agents with respect to such Debt Securities or by Olin if such
Debt Securities are offered and sold directly by Olin. Ownership of beneficial
interests in a Global Security will be limited to persons that have accounts
with the applicable Depositary ("participants") or persons that may hold
interests through participants. Ownership of beneficial interests in such Global
Security will be shown on, and the transfer of that ownership will be effected
only through, records maintained by the applicable Depositary or its nominee
(with respect to interests of participants) and the records of participants
(with respect to interests of persons other than participants). The laws of some
states require that certain purchasers of securities take physical delivery of
such securities in definitive form. Such limits and such laws may impair the
ability to transfer beneficial interests in a Global Security.
 
     So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture governing such Debt Securities. Except as provided below, owners of
beneficial interests in a Global Security will not be entitled to have any of
the individual Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of any such Debt Securities of such series in definitive form and will
not be considered the owners or holders thereof under the Indenture governing
such Debt Securities.
 
                                        7

     Payments of principal of, premium, if any, and interest, if any, on
individual Debt Securities represented by a Global Security registered in the
name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Security
representing such Debt Securities. Neither Olin, the Trustee for such Debt
Securities, any paying agent (a "Paying Agent"), nor the Registrar for such Debt
Securities will have any responsibility or liability for any aspect of the
records relating to or payments made by the Depository or any participants on
account of beneficial ownership interests of the Global Security for such Debt
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
     Olin expects that the Depositary for a series of Debt Securities or its
nominee, upon receipt of any payment of principal, premium or interest in
respect of a permanent Global Security representing any of such Debt Securities,
immediately will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Global Security for such Debt Securities as shown on the records of such
Depositary or its nominee. Olin also expects that payments by participants to
owners of beneficial interests in such Global Security 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 in bearer
form or registered in "street name". Such payments will be the responsibility of
such participants.
 
     If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is not
appointed by Olin within 90 days, Olin will issue individual Debt Securities of
such series in exchange for the Global Security or Securities representing such
series of Debt Securities. In addition, Olin may at any time and in its sole
discretion, subject to any limitations described in the Prospectus Supplement
relating to such Debt Securities, determine not to have any Debt Securities of a
series represented by one or more Global Securities and, in such event, will
issue individual Debt Securities of such series in exchange for the Global
Security or Securities representing such series of Debt Securities. Further, if
Olin so specifies with respect to the Debt Securities of a series, an owner of a
beneficial interest in a Global Security representing Debt Securities of such
series may, on terms acceptable to Olin, the Trustee, and the Depositary for
such Global Security, receive individual Debt Securities of such series in
exchange for such beneficial interests, subject to any limitations described in
the Prospectus Supplement relating to such Debt Securities. In any such
instance, an owner of a beneficial interest in a Global Security will be
entitled to physical delivery of individual Debt Securities of the series
represented by such Global Security equal in principal amount to such beneficial
interest and to have such Debt Securities registered in its name. Individual
Debt Securities of such series so issued will be issued in denominations, unless
otherwise specified by Olin, of $1,000 and integral multiples thereof.
 
SUBORDINATION OF SUBORDINATED SECURITIES
 
     The payment of the principal of, premium, if any, and interest on the
Subordinated Securities, including sinking fund payments, if any, is
subordinated in right of payment, as set forth in the Subordinated Indenture, to
the prior payment in full of all Superior Indebtedness of Olin. Superior
Indebtedness is defined as (a) the principal of, premium, if any, and accrued
and unpaid interest on (whether outstanding on the date of execution of the
Subordinated Indenture or thereafter created, incurred or assumed) (i)
indebtedness of Olin for money borrowed (other than the Subordinated
Securities), (ii) guarantees by Olin of indebtedness for money borrowed of any
other person, (iii) indebtedness evidenced by notes, debentures, bonds or other
instruments of indebtedness for the payment of which Olin is responsible or
liable, by guarantees or otherwise, (iv) obligations of Olin under any agreement
relating to any interest rate or currency swap, interest rate cap, interest rate
collar, interest rate future, currency exchange or forward currency transaction,
or any similar interest rate or currency hedging transaction, whether
outstanding on the date of the Subordinated Indenture or thereafter created,
incurred or assumed, and (v) obligations of Olin under any agreement to lease,
or any lease of, any real or personal property which, in accordance with
generally accepted accounting principles, is classified on Olin's balance sheet
as a liability, and (b) modifications, renewals, extensions and refundings of
any such indebtedness, liability, obligation or guarantee; unless, in the
instrument creating or evidencing the same or pursuant to which the same is
outstanding, it is provided that such indebtedness, liability, obligation or
guarantee, or such modification, renewal, extension or refunding thereof, is not
superior in right of payment to
 
                                        8
<PAGE>   36
 
the Subordinated Securities; provided, however, that Superior Indebtedness shall
not be deemed to include (i) any obligation of Olin to any subsidiary and (ii)
any other indebtedness, guarantee or obligation of Olin of the type set forth
above which is subordinate or junior in ranking in any respect to any other
indebtedness, guarantee or obligation of Olin.
 
     No payment by Olin on account of principal of, premium, if any, or interest
on the Subordinated Securities, including sinking fund payments, if any, may be
made if any default or event of default with respect to any Superior
Indebtedness shall have occurred and be continuing and (unless such default or
event of default is the failure by Olin to pay principal or interest on any
instrument constituting Superior Indebtedness) written notice thereof shall have
been given to the Trustee by Olin or to Olin and the Trustee by the holders of
at least 10% in principal amount of any kind or category of any Superior
Indebtedness (or a representative or trustee on their behalf). Olin may resume
payments on the Subordinated Securities (unless otherwise prohibited by the
related Indenture) if (i) such default is cured or waived or (ii) unless such
default is the failure of Olin to pay principal or interest on any Superior
Indebtedness, 120 days pass after the notice is given if such default is not the
subject of judicial proceedings. In the event that any Subordinated Security is
declared due and payable before the date specified therein as the fixed date on
which the principal thereof is due and payable, or upon any payment or
distribution of assets of Olin to creditors upon any dissolution, winding up,
liquidation or reorganization, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all principal of (and
premium, if any) and interest due or to become due on all Superior Indebtedness
must be paid in full before the holders of Subordinated Securities are entitled
to receive or retain any payment (other than shares of stock or subordinated
indebtedness provided by a plan of reorganization or adjustment which does not
alter the rights of holders of Superior Indebtedness without such holders'
consent). Subject to the payment in full of all Superior Indebtedness, the
holders of the Subordinated Securities are to be subrogated to the rights of the
holders of Superior Indebtedness to receive payments or distributions of assets
of Olin applicable to Superior Indebtedness until the Subordinated Securities
are paid in full.
 
     By reason of such subordination, in the event of insolvency, creditors of
Olin who are holders of Superior Indebtedness, as well as certain general
creditors of Olin, may recover more, ratably, than the holders of the
Subordinated Securities.
 
     The Subordinated Indenture will not limit the amount of Superior
Indebtedness or securities which may be issued by Olin or any of its
subsidiaries.
 
CERTAIN COVENANTS OF OLIN WITH RESPECT TO SENIOR SECURITIES
 
     Limitations on Liens.  (a) Olin will agree that neither it nor any
Restricted Subsidiary (as defined below) will issue, assume or guarantee any
notes, bonds, debentures or other similar evidences of indebtedness for money
borrowed ("Debt") secured by a mortgage, lien, pledge or other encumbrance
("Mortgages") upon any Principal Property (as defined below), or upon any shares
of stock of any Restricted Subsidiary, without effectively providing that the
Senior Securities (together with, if Olin so determines, any other indebtedness
or obligation then existing or thereafter created, ranking equally with the
Senior Securities) shall be secured equally and ratably with (or, at the option
of Olin, prior to) such Debt so long as such Debt shall be so secured, except
that this restriction will not apply to (i) Mortgages existing on the date of
the Senior Indenture; (ii) Mortgages affecting property of a corporation
existing at the time it becomes a Restricted Subsidiary or at the time it is
merged into or consolidated with Olin or a Restricted Subsidiary; (iii)
Mortgages on property existing at the time of acquisition thereof, or to secure
payment of all or part of the purchase price thereof, or to secure Debt incurred
prior to, at the time of or within 24 months after such acquisition for the
purpose of financing all or part of the purchase price thereof, or assumed or
incurred in connection with the acquisition of property; (iv) Mortgages on
property to secure all or part of the cost of repairing, altering, constructing,
improving, exploring, drilling or developing such property, or to secure Debt
incurred to provide funds for such purpose; (v) Mortgages in connection with
non-recourse Debt; (vi) Mortgages on current assets or other personal property
(other than shares of stock or indebtedness of Subsidiaries (as defined below))
to secure loans maturing not more than one year from the date of the creation
thereof or to secure any renewal thereof for not more than one year at any one
time; (vii) Mortgages
 
                                        9
<PAGE>   37
 
which secure indebtedness owing by a Restricted Subsidiary to Olin or a
Subsidiary; (viii) Mortgages on property of any Restricted Subsidiary
principally engaged in a financing or leasing business; (ix) Mortgages incurred
which do not in the aggregate materially detract from the value of the property
or assets affected thereby or materially impair the use of such property or
assets in the operation of its business; and (x) any extension, renewal or
replacement (or successive extensions, renewals or replacements), in whole or in
part, of any Mortgage referred to in the foregoing or of any Debt secured
thereby, provided that the principal amount of Debt secured thereby shall not,
with respect to Mortgages referred to in clauses (i) through (iv) above, exceed
the principal amount of Debt so secured at the time of such extension, renewal
or replacement, and that such extension, renewal or replacement Mortgage shall
be limited to all or part of substantially the same property which secured the
Mortgage extended, renewed or replaced (plus improvements on such property).
 
     (b) Notwithstanding the above, Olin and any one or more Restricted
Subsidiaries may, without securing the Senior Securities, issue, assume or
guarantee Debt secured by Mortgages which would not be permitted by the
immediately preceding paragraph in an aggregate amount which, together with (i)
all other such Debt of Olin and its Restricted Subsidiaries which would not be
permitted under the immediately preceding paragraph and (ii) the Attributable
Debt (as defined below) in respect of Sale and Lease-Back Transactions (as
defined in the Senior Indenture) existing at such time (other than Sale and
Lease-Back Transactions in which the property involved would have been permitted
to be mortgaged under this section "Limitations on Liens" or the proceeds of
which have been applied to the retirement of long term indebtedness), does not
at the time exceed 10% of Consolidated Net Tangible Assets. The term
"Consolidated Net Tangible Assets" means the total amount of assets after
deducting therefrom (i) all current liabilities (excluding any thereof which are
by their terms extendible or renewable at the option of the obligor thereon to a
time more than 12 months after the time as of which the amount thereof is being
computed), and (ii) unamortized Debt discount and expense, goodwill, trademarks,
brand names, patents and other intangible assets, all as shown on the latest
audited consolidated financial statements of the Company at the time of the
determination.
 
     (c) For purposes of this covenant, the following are not considered Debt
secured by a Mortgage: (i) the sale or other transfer of any interest in
property of the character commonly referred to as a "production payment" and
(ii) Mortgages in favor of governmental bodies to secure advance or progress
payments pursuant to any contract or statute or indebtedness incurred for the
purpose of financing the purchase price or cost of constructing or improving the
property subject thereto.
 
     Sale and Lease-Back Transactions.  (a) Sale and Lease-Back Transactions
with respect to Principal Property by Olin or any Restricted Subsidiary (except
for temporary leases for terms of not more than three years or between the
Company or a Subsidiary and a Restricted Subsidiary) are prohibited by the
Senior Indenture unless the proceeds of any such sale are at least equal to the
fair value of such property and either (i) Olin or such Restricted Subsidiary
would be entitled to incur, assume or guarantee Debt secured by a mortgage on
the Principal Property to be leased without equally and ratably securing the
Senior Securities or (ii) Olin applies an amount equal to the fair value of the
property so leased to the retirement of long-term indebtedness of Olin which
ranks prior to or on a par with the Senior Securities. Sale and Lease-Back
Transactions do not include arrangements with governmental bodies entered into
for the purpose of financing the purchase price or the cost of constructing or
improving the property subject thereto.
 
     (b) Notwithstanding the provisions of the preceding paragraph (a), Olin or
any Restricted Subsidiary may enter into any Sale and Lease-Back Transaction
which would not be permitted under the immediately preceding paragraph if the
amount of the Attributable Debt in respect of Sale and Lease-Back Transactions
for such transaction, together with (i) all Debt of Olin and its Restricted
Subsidiaries secured by a Mortgage on Principal Property and not permitted under
paragraph (a) of "Limitations on Liens" and (ii) all other Attributable Debt in
respect of Sale and Lease-Back Transactions existing at such time (other than
Sale and Lease-Back Transactions permitted because Olin would be entitled to
incur, assume or guarantee Debt secured by a Mortgage on the Principal Property
to be leased without equally and ratably securing the Senior Securities and
other than Sale and Lease-Back Transactions the proceeds of which have been
applied in accordance with clause (ii) of the immediately preceding paragraph
(a)), does not at the time exceed 10% of Consolidated Net Tangible Assets.
 
                                       10
<PAGE>   38
 
     The term "Principal Property" means any property or plant of Olin or any
Restricted Subsidiary primarily used for the manufacture of products and located
within the United States or its territories or possessions, except any such
property or plant which the Board of Directors of Olin by resolution declares is
not of material importance to the total business conducted by Olin and its
Subsidiaries as an entity.
 
     The term "Attributable Debt" means, as of any particular time, the present
value, discounted at a rate per annum equal to the weighted average of the
interest rate(s) of the Senior Securities, or, in the case of Original Issue
Discount Debt Securities (as defined in the Senior Indenture), the Yields to
Maturity (as defined in the Senior Indenture) (compounded semi-annually), of the
obligation of a lessee for rental payments (not including amounts payable by the
lessee for maintenance, property taxes and insurance) due during the remaining
term of any lease (including any period for which such lease has been extended
or may, at the option of the lessor, be extended).
 
     The term "Subsidiary" means any corporation, association or other business
entity of which more than 50% of the Voting Stock (as defined in the Senior
Indenture) is at the time directly or indirectly owned by Olin. The term
"Restricted Subsidiary" means (i) any Subsidiary which owns or leases, directly
or indirectly, a Principal Property, and (ii) any Subsidiary which owns,
directly or indirectly, any stock or indebtedness of a Restricted Subsidiary;
except that the term "Restricted Subsidiary" shall not include (A) any
Subsidiary engaged primarily in financing receivables, making loans, extending
credit or other activities of a character conducted by a finance company, or (B)
any Subsidiary (1) which conducts substantially all of its business outside the
United States or its territories and possessions or (2) the principal assets of
which are stock or indebtedness of corporations which conduct substantially all
of their business outside the United States and its territories and possessions.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     The following events are defined in each Indenture as "Events of Default"
with respect to a series of Debt Securities issued under such Indenture: (a)
failure to pay interest or a sinking fund installment, if any, on such series
for 30 days or to pay the principal of and premium, if any, on such series when
due, whether at maturity, upon redemption, by declaration or otherwise; (b)
failure to perform any other covenants in such Indenture for 60 days after
notice; and (c) certain events of bankruptcy, insolvency or reorganization. An
Event of Default with respect to one series of Debt Securities is not
necessarily an Event of Default for another series.
 
     If an Event of Default described under (a) above shall have occurred and is
continuing with respect to any series of Debt Securities, unless the principal
of all the Debt Securities of such series shall have already become due and
payable, either the Trustee or the holders of not less than 25% in aggregate
principal amount of the Debt Securities of such series then outstanding may
declare the principal amount (or, if original issue discount securities, such
portion of the principal amount as specified in such series of Debt Securities)
of all Debt Securities of such series immediately due and payable. If an Event
of Default described under (b) above shall have occurred and is continuing,
unless the principal amount of all the Debt Securities of all series shall have
already become due and payable, either the Trustee or the holders of not less
than 25% in aggregate principal amount of all Debt Securities then outstanding
may declare the principal amount (or, if any series are original issue discount
securities, such portion of the principal amount as specified in such series) of
all Debt Securities then outstanding immediately due and payable.
 
     Each of the Indentures provides that the Trustee under such Indenture
shall, within 90 days after the occurrence of a default with respect to a series
of Debt Securities under such Indenture, give to the holders of the Debt
Securities in such series notice of all uncured defaults with respect to such
series known to it; provided that, except in the case of default in the payment
of principal of or premium, if any, or interest or the making of any sinking
fund payment on any of the Debt Securities in such series, the Trustee shall be
protected in withholding such notice if it in good faith determines that it is
in the interest of the holders of such series.
 
     Any Event of Default with respect to a particular series of Debt Securities
may be waived by the holders of a majority in aggregate principal amount of the
Outstanding Debt Securities (as defined in the Indentures)
 
                                       11
<PAGE>   39
 
of such series (or of all the Outstanding Debt Securities, as the case may be),
except in each case a failure to pay principal of, premium, if any, or interest
on such Debt Security.
 
MODIFICATION OF THE INDENTURES
 
     Each of the Indentures and the rights of holders of Debt Securities
thereunder may be modified by Olin and the respective Trustee with the consent
of the holders of not less than 66 2/3% of the aggregate principal amount of all
series of Debt Securities under such Indenture then outstanding affected thereby
(voting as one class); provided, however, that no such modification shall extend
the fixed maturity of any Debt Securities, or reduce the principal amount
thereof or any premium thereon or the amount of any sinking fund payment, or
reduce the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, or reduce the percentage required
for modification, without the consent of the holder of each Debt Security so
affected.
 
     Each of the Indentures provides that the Company and the Trustee may enter
into supplemental indentures without the consent of the holders of Debt
Securities to: (a) evidence the assumption by a successor corporation of the
obligations of the Company, (b) add covenants for the protection of the holders
of Debt Securities, (c) cure any ambiguity or correct any inconsistency in
either of the Indentures, (d) establish the form or terms of Debt Securities of
any series, (e) modify or amend either of the Indentures to permit the
qualification of indentures supplemental thereto and (f) provide for the
issuance under either of the Indentures of Debt Securities in coupon form
exchangeable with Debt Securities issued under the Indentures.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     Each of the Indentures provides that the Company may not merge or
consolidate with any other corporation or sell or convey all or substantially
all of its assets to any Person (as defined in each of the Indentures), unless
(a) the successor corporation shall be a corporation organized under the laws of
the United States of America or any State thereof and shall expressly assume the
due and punctual payment of the principal of and premium, if any, and interest
on all the Debt Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of the
Indentures to be performed or observed by the Company, by supplemental indenture
satisfactory to the Trustee, executed and delivered to the Trustee by such
corporation, and (b) the successor corporation shall not, immediately after such
merger or consolidation, or such sale or conveyance, be in default in the
performance of any such covenant or condition.
 
SATISFACTION AND DISCHARGE OF THE INDENTURES; DEFEASANCE; COVENANT DEFEASANCE
 
     The Subordinated Indenture will be discharged upon cancellation of all the
Subordinated Securities or, with certain limitations, upon deposit with the
respective Trustee of funds sufficient for the payment or redemption thereof.
 
     The Senior Indenture provides that Olin, at Olin's option, (a) will be
discharged from any and all obligations in respect of the Senior Securities of a
series (except for certain obligations to register the transfer or exchange of
Debt Securities, replace stolen, lost or mutilated Debt Securities, maintain
paying agencies and hold moneys for payment in trust) or (b) need not comply
with certain restrictive covenants of such Indenture (including those described
under "Certain Covenants of Olin With Respect To Senior Securities"), in each
case if Olin deposits, in trust with the Trustee or the Defeasance Agent (as
defined in the Senior Indenture), money or U.S. Government Obligations (as
defined in the Senior Indenture), or any combination thereof, which through the
payment of interest thereon and principal thereof in accordance with their terms
will provide money, in an amount sufficient to pay all the principal (including
any mandatory sinking fund payments) of, and interest and premium, if any, on,
the Senior Securities of such series on the dates such payments are due in
accordance with the terms of such Senior Securities. To exercise any such
option, Olin is required to deliver to the Trustee and the Defeasance Agent, if
any, an opinion of counsel to the effect that (i) the deposit and related
defeasance would not cause the holders of the Senior Securities of such series
to recognize income, gain or loss for federal income tax purposes and, in the
case of a discharge pursuant to
 
                                       12
<PAGE>   40
 
clause (a), such opinion shall be accompanied by a private letter ruling to that
effect received from the United States Internal Revenue Service or a revenue
ruling pertaining to a comparable form of transaction to that effect published
by the United States Internal Revenue Service, and (ii) if listed on any
national securities exchange, such Debt Securities would not be delisted from
such exchange as a result of the exercise of such option.
 
THE TRUSTEES
 
     Olin may maintain banking and other commercial relationships with the
Trustees and their affiliates in the ordinary course of business.
 
                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The authorized stock of the Company consists of 60,000,000 shares of common
stock, par value $1 per share (the "Common Stock"), and 10,000,000 shares of
preferred stock, par value $1 per share (the "Preferred Stock"), issuable in
series. On March 3, 1994, there were approximately 19,116,000 shares of Common
Stock, 1,172,000 shares of ESOP Preferred Stock (the "ESOP Preferred") and
2,760,000 shares of Series A Conversion Preferred Stock (the "PERCS")
outstanding.
 
     The following statements with respect to the capital stock of the Company
are subject to the detailed provisions of the Company's Restated Articles of
Incorporation, as amended (the "Restated Articles"), and by-laws (the "By-Laws")
as currently in effect. These statements do not purport to be complete, or to
give full effect to the terms of the provisions of statutory or common law, and
are subject to, and are qualified in their entirety by reference to, the terms
of the Restated Articles, By-Laws and the Rights Agreement, dated as of February
27, 1986 between the Company and Manufacturers Hanover Trust Company (now known
as Chemical Bank) (the "Rights Agreement"), which are filed as Exhibits to the
Registration Statement of which this Prospectus is a part.
 
Preferred Stock
 
     The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which a
Prospectus Supplement may relate. Specific terms of any series of the Preferred
Stock offered by a Prospectus Supplement will be described in the Prospectus
Supplement relating to such series of the Preferred Stock. The description set
forth below is subject to and qualified in its entirety by reference to the
Articles of Amendment to the Restated Articles establishing a particular series
of the Preferred Stock which will be filed with the Commission in connection
with the offering of such series of Preferred Stock.
 
     General.  Under the Restated Articles, the Board of Directors of the
Company (the "Board of Directors") is authorized, without further shareholder
action, to provide for the issuance of up to 10,000,000 shares of preferred
stock, $1 par value per share, in one or more series, with such voting powers
and with such designations, preferences and relative, participating, optional or
other special rights, and qualifications, limitations or restrictions, as shall
be set forth in resolutions providing for the issue thereof adopted by the Board
of Directors or a duly authorized committee thereof. The Company may amend from
time to time its Restated Articles to increase the number of authorized shares
of preferred stock. Any such amendment would require the approval of the holders
of a majority of the outstanding shares of Common Stock, and the approval of the
holders of a majority of the outstanding shares of all series of preferred stock
voting together as a single class without regard to series. As of the date of
this Prospectus, the Company has two series of preferred stock outstanding,
which are described below under "Outstanding Preferred Stock".
 
     The Preferred Stock will have the dividend, liquidation, redemption,
conversion and voting rights set forth below unless otherwise provided in the
Prospectus Supplement relating to a particular series of the Preferred Stock.
Reference is made to the Prospectus Supplement relating to the particular series
of the Preferred Stock
 
                                       13
<PAGE>   41
 
offered thereby for specific terms, including: (i) the title and liquidation
preference per share of such Preferred Stock and the number of shares offered;
(ii) the price at which such Preferred Stock will be issued; (iii) the dividend
rate (or method of calculation), the dates on which dividends shall be payable,
whether such dividends shall be cumulative or noncumulative and, if cumulative,
the dates from which dividends shall commence to accumulate; (iv) any redemption
or sinking fund provisions of such Preferred Stock; (v) any conversion
provisions of such Preferred Stock; and (vi) any additional dividend,
liquidation, redemption, sinking fund and other rights, preferences, privileges,
limitations and restrictions of such Preferred Stock.
 
     The Preferred Stock will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the Prospectus Supplement relating to a particular
series of the Preferred Stock, each series of the Preferred Stock will rank on a
parity as to dividends and distributions in the event of a liquidation with the
outstanding preferred stock of the Company and each other series of the
Preferred Stock. See "Outstanding Preferred Stock" below.
 
     Dividend Rights.  Holders of the Preferred Stock of each series will be
entitled to receive, when, as and if declared by the Board of Directors, out of
assets of the Company 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 the Preferred Stock. Such rate may be fixed or variable or both. Each
such dividend will be payable to the holders of record as they appear on the
stock books of the Company on such record dates as will be fixed by the Board of
Directors or a duly authorized committee thereof. Dividends on any series of the
Preferred Stock may be cumulative or noncumulative, as provided in the
Prospectus Supplement relating thereto. If the Board of Directors fails to
declare a dividend payable on a dividend payment date on any series of Preferred
Stock for which dividends are noncumulative, then the right to receive a
dividend in respect of the dividend period ending on such dividend payment day
will be lost, and the Company shall have no obligation to pay the dividend
accrued for that period, whether or not dividends are declared for any future
period.
 
     If the Prospectus Supplement so provides, no full dividends will be
declared or paid or set apart for payment on the Preferred Stock of any series
ranking, as to dividends, on a parity with or junior to any other series of
preferred stock for any period unless full dividends have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof set apart for such payment, on such other series of
preferred stock for the then-current dividend payment period and, if such other
preferred stock is cumulative, all other dividend payment periods terminating on
or before the date of payment of such full dividends. If the Prospectus
Supplement so provides, when dividends are not paid in full upon any series of
the Preferred Stock and any other preferred stock ranking on a parity as to
dividends with such series of the Preferred Stock, all dividends declared upon
such series of the Preferred Stock and any other preferred stock ranking on a
parity as to dividends will be declared pro rata so that the amount of dividends
declared per share on such series of the Preferred Stock and such other
preferred stock will in all cases bear to each other the same ratio that accrued
dividends per share on such series of the Preferred Stock and such other
preferred stock bear to each other. Except as provided in the preceding
sentence, unless full dividends, including, in the case of cumulative Preferred
Stock, accumulations, if any, in respect of prior dividend payment periods, on
all outstanding shares of any series of the Preferred Stock have been paid, no
dividends (other than in shares of Common Stock or another stock ranking junior
to such series of the Preferred Stock as to dividends and upon liquidation) will
be declared or paid or set aside for payment or other distributions made upon
the Common Stock or any other stock of the Company ranking junior to the
Preferred Stock as to dividends. If the Prospectus Supplement so provides, no
Common Stock or any other stock of the Company ranking junior to or on a parity
with such series of the Preferred Stock as to dividends or upon liquidation be
redeemed, purchased or otherwise acquired for any consideration (or any moneys
be paid to or made available for a sinking fund for the redemption of any shares
of any such stock) by the Company (except by conversion into or exchange for
 
                                       14
<PAGE>   42
 
stock of the Company ranking junior to such series of the Preferred Stock as to
dividends and upon liquidation).
 
     The amount of dividends payable for each dividend period will be computed
by annualizing the applicable dividend rate and dividing by the number of
dividend periods in a year, except that the amount of dividends payable for the
initial dividend period or any period shorter than a full dividend period shall
be computed on the basis of 30-day months, a 360-day year and the actual number
of days elapsed in the period.
 
     Each series of Preferred Stock will be entitled to dividends as described
in the Prospectus Supplement relating to such series, which may be based upon
one or more methods of determination. Different series of the Preferred Stock
may be entitled to dividends at different dividend rates or based upon different
methods of determination.
 
     Rights Upon Liquidation.  In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the holders of each
series of Preferred Stock will be entitled to receive out of the assets of the
Company available for distribution to shareholders, before any distribution of
assets is made to holders of Common Stock or any other class of stock ranking
junior to such series of Preferred Stock upon liquidation, liquidating
distributions in the amount set forth in the Prospectus Supplement relating to
such series of the Preferred Stock. 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 shares of stock of
the Company ranking as to any such distribution on a parity with such series of
the Preferred Stock are not paid in full, the holders of the Preferred Stock of
such series and of such other shares will share ratably in any such distribution
of assets of the Company in proportion to the full respective preferential
amounts to which they are entitled.
 
     Redemption.  A series of the Preferred Stock may be redeemable, in whole or
in part, at the option of the Company, and may be subject to mandatory
redemption pursuant to a sinking fund, in each case upon terms, at the time, the
redemption prices and for the types of consideration set forth in the Prospectus
Supplement relating to such series.
 
     The Prospectus Supplement relating to a series of Preferred Stock which is
subject to mandatory redemption shall specify the number of shares of such
series of Preferred Stock which shall be redeemed by the Company in each year
commencing after a date to be specified, at a redemption price per share to be
specified, together with an amount equal to any accrued and unpaid dividends
thereon to the date of redemption.
 
     Conversion Rights.  The Prospectus Supplement for any series of the
Preferred Stock will state the terms, if any, on which shares of that series are
convertible into shares of Common Stock or another series of preferred stock of
the Company. The Preferred Stock will have no preemptive rights.
 
     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, a holder of the Preferred Stock will not be entitled
to vote. Except as indicated in the Prospectus Supplement relating to a
particular series of Preferred Stock, in the event the Company issues full
shares of any series of Preferred Stock, each such share will be entitled to one
vote on matters on which holders of such series of the Preferred Stock are
entitled to vote.
 
     The affirmative vote or consent of the holders of a majority of the
outstanding shares of any series of Preferred Stock (unless the Board of
Directors establishes a higher amount), voting as a separate class, will be
required for any amendment of the Restated Articles (or any certificate
amendatory thereof or supplemental thereto relating to any series of the
Preferred Stock) which changes any rights or preferences of such series of
Preferred Stock.
 
     In addition to the foregoing voting rights, under Virginia law as now in
effect, the holders of the Preferred Stock will have the voting rights set forth
under "General" above with respect to amendments to the Restated Articles which
would increase the number of authorized shares of preferred stock of the
Company.
 
                                       15

     Outstanding Preferred Stock.  As of March 3, 1994, the Company had two
series of Preferred Stock outstanding, PERCS and ESOP Preferred. The PERCS and
the ESOP Preferred rank on a parity with respect to each other and rank senior
to the Common Stock with respect to payment of dividends and rights upon
liquidation.
 
     PERCS.  Subject to the rights of holders of other classes of stock ranking
on a parity with or senior to the PERCS with respect to the payment of dividends
which may from time to time be issued by the Company, the owners of the PERCS
are entitled to receive, when, as and if the Board of Directors declares a
dividend on the PERCS, cumulative preferential cash dividends accruing at the
rate of $3.64 per annum or $.91 per quarter for each share of the PERCS.
Dividends on the PERCS accrue whether or not the Company has earnings, whether
or not there are funds legally available for the payment of such dividends and
whether or not such dividends are declared. Accumulated unpaid dividends will
not bear interest.
 
     On the Mandatory Conversion Date, March 1, 1995, the outstanding PERCS will
convert automatically into shares of Common Stock at the Common Equivalent Rate
(as described below) in effect on such date and the right to receive an amount
in cash equal to all accrued and unpaid dividends on such PERCS, subject to the
rights of the Company to call the PERCS for redemption prior to the Mandatory
Conversion Date, as described below. The Common Equivalent Rate is initially one
share of the Common Stock for each PERCS. The Common Equivalent Rate is subject
to adjustment under certain circumstances.
 
     In addition, (x) immediately prior to the effectiveness of a merger or
consolidation of the Company that results in the conversion or exchange of the
Common Stock into, or results in holders of the Common Stock having the right to
receive, other securities or other property (whether of the Company or any other
entity) or (y) immediately prior to the close of business on the business day
immediately preceding the distribution date of the Rights associated with the
Common Stock, each outstanding share of the PERCS will convert automatically
into (i) shares of Common Stock, plus (ii) the right to receive an amount in
cash equal to the accrued and unpaid dividends on such PERCS to and including
the settlement date, plus (iii) the right to receive an amount in cash initially
equal to $4.32, declining by $.00386 on each day following the date of issue of
the PERCS to $.23 on January 1, 1995, and equal to zero thereafter. At the
option of the Company, it may deliver on the settlement date, in lieu of some or
all of the cash amounts described in clauses (i) and (iii) of the preceding
sentence, shares of Common Stock.
 
     The PERCS are not convertible into shares of Common Stock at the option of
the holders thereof.
 
     At any time and from time to time prior to the Mandatory Conversion Date,
the Company shall have the right to call, in whole or in part, the outstanding
PERCS for redemption and to deliver to the holders thereof in exchange for each
such share of the PERCS, a number of shares of Common Stock equal to the call
price in effect on the date of redemption divided by the current market price of
the Common Stock determined as of the second trading day immediately preceding
the notice date, plus an amount in cash equal to any accrued and unpaid
dividends to and including the date of redemption.
 
     In the event of the liquidation, dissolution or winding up of the business
of the Company, whether voluntary or involuntary, the holders of the PERCS,
after payment or provision for payment of the debts and other liabilities of the
Company and before any distribution to the holders of the Common Stock or any
other stock ranking junior to the PERCS with respect to distributions upon
liquidation, dissolution or winding up, will be entitled to receive, for each
share of the PERCS, an amount equal to the sum of (i) the price to public for
each share of the PERCS and (ii) all accrued and unpaid dividends thereon, and
no more.
 
     The holders of PERCS do not have voting rights except as required by law
and except that (i) upon the failure of the Company to pay dividends on the
PERCS in full for six quarterly dividend periods, the holders of the PERCS
(together with the holders of all other series of the Preferred Stock having
such rights) will be entitled to elect two directors to the Board of Directors
until the default is cured and (ii) any amendment of any of the provisions of
the Restated Articles which would (A) authorize or create any shares of stock
ranking senior to the PERCS as to dividends or as to distributions in the event
of the Company's liquidation, dissolution or winding up or (B) alter or change
the rights, preferences or limitations of the PERCS so as to affect such rights,
preferences or limitations adversely would require the affirmative vote of the
holders of at
 
                                       16
<PAGE>   44
 
least two-thirds of the total number of outstanding shares of the PERCS, voting
together as a single voting group with any other series of the Preferred Stock
that is (x) affected in the same or substantially similar manner and (y)
entitled by law, by the Restated Articles or by resolution of the Board of
Directors to vote on such amendment.
 
     ESOP Preferred Stock.  The Board of Directors, by amendment to the Restated
Articles effective June 27, 1989, established 1,750,000 shares of ESOP
Preferred. The ESOP Preferred is issuable only to the trustee of the Olin
Corporation Contributing Employee Ownership Plan, which purchased 1,298,195
shares of such stock on June 29, 1989. The ESOP Preferred has a liquidation
value of $77.03 per share (plus accrued and unpaid dividends) and cumulative
annual dividends of $5.97 per share. Subject to Virginia law, each share of ESOP
Preferred is currently entitled to one vote and is voted with the Common Stock
as a single class on matters submitted to a vote of the Company's shareholders.
Each share of ESOP Preferred is convertible into not less than one share of
Common Stock, subject to anti-dilutive adjustments. The ESOP Preferred may be
redeemed at the option of the Company after July 1, 1994, or at the option of
the trustee of such Plan under certain circumstances (including upon payment of
withdrawing Plan participant accounts or if required to meet ESOP debt
payments). The Company may pay the redemption price with cash, marketable
securities or shares of Common Stock or in any combination of the foregoing.
Currently, the Company intends to redeem the ESOP Preferred solely with shares
of Common Stock whenever mandatory redemptions occur as a result of Plan
participants withdrawing their accounts.
 
     Transfer Agent and Registrar.  The transfer agent, registrar and dividend
disbursement agent for a series of the Preferred Stock will be selected by the
Company and be described in the applicable Prospectus Supplement. The registrar
for shares of Preferred Stock will send notices to shareholders of any meetings
at which holders of the Preferred Stock have the right to elect directors of the
Company or to vote on any other matter.
 
Common Stock
 
     Holders of Common Stock are entitled to dividends as declared by the Board
of Directors from time to time after payment of, or provision for, full
cumulative dividends on and any required redemptions of shares of Preferred
Stock then outstanding. Holders of Common Stock are entitled to one vote per
share and may not cumulate votes for the election of directors. Holders of
Common Stock have no preemptive or subscription rights and have no liability for
further calls or assessments. In the event of the liquidation, dissolution or
winding up of the Company, holders of Common Stock are entitled to receive pro
rata all the remaining assets of the Company available for distribution, after
satisfaction of the prior preferential rights of the Preferred Stock and the
satisfaction of all debts and liabilities of the Company.
 
     The Transfer Agent and Registrar for the Common Stock is Chemical Bank.
 
CERTAIN PROVISIONS OF THE RESTATED ARTICLES AND BY-LAWS
 
     The Board of Directors consists of three classes as nearly equal in number
as possible, each of which serves for three years with one class being elected
each year. The total number of Directors may not exceed 18. Special meetings of
shareholders may be called only by the Board of Directors, designated officers
or the holders of a majority of the shares entitled to vote at the special
meeting. Directors may be removed only with cause, and vacancies on the Board of
Directors, including any vacancy created by an increase in the number of
Directors, may be filled only by the Board of Directors unless the vacancy is to
be filled at an annual meeting of shareholders. The By-Laws require that advance
notice of nominees for election as Directors to be made by a shareholder be
given to the Secretary of the Company, together with certain specified
information, no later than 90 days before an annual meeting of shareholders or
seven days following notice of a special meeting of shareholders for the
election of Directors. The provisions of the Restated Articles and By-Laws
described above may, in certain circumstances, make more difficult or discourage
a takeover of the Company.
 
COMMON STOCK PURCHASE RIGHTS
 
     On February 27, 1986, the Company distributed one Common Stock purchase
right ("Right") for each outstanding share of Common Stock to the shareholders
of record on March 10, 1986. Unless the Board of
 
                                       17
<PAGE>   45
 
Directors directs otherwise, one Right will be issued with respect to each share
of Common Stock that becomes outstanding prior to the occurrence of certain
potential change-in-control events. The Rights become exercisable upon certain
potential change-in-control events. When exercisable and upon the occurrence of
certain events, the Rights entitle holders to purchase shares of Common Stock at
a substantial discount. Exercise of the Rights will cause substantial dilution
to a person or group attempting to acquire control of the Company without the
approval of the Board of Directors. Except under certain circumstances, the
Board of Directors may cause the Company to redeem the Rights in whole, but not
in part, at a price of $.05 per Right. The Rights will not interfere with any
merger or other business combination approved by the Board of Directors. The
Rights expire on February 27, 1996, if not redeemed earlier. The Rights have no
voting or dividend privileges. Until such time as the Rights become exercisable,
they are attached to and do not trade separately from the Common Stock.
 
                       DESCRIPTION OF SECURITIES WARRANTS
 
     The Company may issue Securities Warrants for the purchase of Debt
Securities, Preferred Stock or Common Stock. Securities Warrants may be issued
independently or together with Debt Securities, Preferred Stock or Common Stock
offered by any Prospectus Supplement and may be attached to or separate from any
such Offered Securities. Each series of Securities Warrants will be issued under
a separate warrant agreement (a "Securities Warrant Agreement") to be entered
into between the Company and a bank or trust company, as warrant agent (the
"Securities Warrant Agent"), all as set forth in the Prospectus Supplement
relating to the particular issue of offered Securities Warrants. The Securities
Warrant Agent will act solely as an agent of the Company in connection with the
Securities Warrants and will not assume any obligation or relationship of agency
or trust for or with any holders of Securities Warrants or beneficial owners of
Securities Warrants. The following summary of certain provisions of the
Securities Warrants does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Securities
Warrant Agreements.
 
     Reference is made to the Prospectus Supplement relating to the particular
issue of Securities Warrants offered thereby for the terms of such Securities
Warrants, including, where applicable: (i) the designation, aggregate principal
amount, currencies, denominations and terms of the series of Debt Securities
purchasable upon exercise of Securities Warrants to purchase Debt Securities and
the price at which such Debt Securities may be purchased upon such exercise;
(ii) the designation, number of shares, stated value and terms (including,
without limitation, liquidation, dividend, conversion and voting rights) of the
series of Preferred Stock purchasable upon exercise of Securities Warrants to
purchase shares of Preferred Stock and the price at which such number of shares
of Preferred Stock of such series may be purchased upon such exercise; (iii) the
number of shares of Common Stock purchasable upon the exercise of Securities
Warrants to purchase shares of Common Stock and the price at which such number
of shares of Common Stock may be purchased upon such exercise; (iv) the date on
which the right to exercise such Securities Warrants shall commence and the date
on which such right shall expire (the "Expiration Date"); (v) United States
Federal income tax consequences applicable to such Securities Warrants; and (vi)
any other terms of such Securities Warrants. Securities Warrants for the
purchase of Preferred Stock and Common Stock will be offered and exercisable for
U.S. dollars only. Securities Warrants will be issued in registered form only.
The exercise price for Securities Warrants will be subject to adjustment in
accordance with the applicable Prospectus Supplement.
 
     Each Securities Warrant will entitle the holder thereof to purchase such
principal amount of Debt Securities or such number of shares of Preferred Stock
or Common Stock at such exercise price as shall in each case be set forth in, or
calculable from, the Prospectus Supplement relating to the offered Securities
Warrants, which exercise price may be subject to adjustment upon the occurrence
of certain events as set forth in such Prospectus Supplement. After the close of
business on the Expiration Date (or such later date to which such Expiration
Date may be extended by the Company), unexercised Securities Warrants will
become void. The place or places where, and the manner in which, Securities
Warrants may be exercised shall be specified in the Prospectus Supplement
relating to such Securities Warrants.
 
                                       18
<PAGE>   46
 
     Prior to the exercise of any Securities Warrants to purchase Debt
Securities, Preferred Stock or Common Stock, holders of such Securities Warrants
will not have any of the rights of holders of the Debt Securities, Preferred
Stock or Common Stock, as the case may be, purchasable upon such exercise,
including the right to receive payments of principal of, premium, if any, or
interest, if any, on the Debt Securities purchasable upon such exercise or to
enforce covenants in the applicable Indenture, or to receive payments of
dividends, if any, on the Preferred Stock or Common Stock purchasable upon such
exercise or to exercise any applicable right to vote.
 
                              PLAN OF DISTRIBUTION
 
     Olin may sell the Offered Securities in any of three ways: (i) through
underwriters or dealers; (ii) directly to one or a limited number of
institutional purchasers; or (iii) through agents. The Prospectus Supplement
with respect to the Offered Securities will set forth the terms of the offering
of the Offered Securities, including the name or names of any underwriters,
dealers or agents, the price of the Offered Securities and the net proceeds to
Olin from such sale, any underwriting discounts or other items constituting
underwriters' compensation, any discounts or concessions allowed or reallowed or
paid to dealers and any securities exchanges on which the Offered Securities may
be listed.
 
     If underwriters are used in the sale, the Offered Securities will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The Offered Securities may be offered to the public either through underwriting
syndicates represented by managing underwriters or directly by one or more
investment banking firms or others, as designated. Unless otherwise set forth in
the Prospectus Supplement, the obligations of the underwriters or agents to
purchase the Offered Securities will be subject to certain conditions precedent
and the underwriters will be obligated to purchase all the Offered Securities if
any are purchased. Any initial public offering price and any discounts or
concessions allowed or reallowed or paid to dealers may be changed from time to
time.
 
     If a dealer is utilized in the sale of any Offered Securities in respect of
which this Prospectus is delivered, the Company will sell such Offered
Securities to the dealer, as principal. The dealer may then resell such Offered
Securities to the public at varying prices to be determined by such dealer at
the time of resale. The name of the dealer and the terms of the transaction will
be set forth in the Prospectus Supplement.
 
     Offered Securities may be sold directly by Olin to one or more
institutional purchasers, or through agents designated by Olin from time to time
at a fixed price or prices, which may be changed, or at varying prices
determined at time of sale. Any agent involved in the offer or sale of the
Offered Securities will be named, and any commissions payable by Olin to such
agent will be set forth, in the Prospectus Supplement. Unless otherwise
indicated in the Prospectus Supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.
 
     If so indicated in the Prospectus Supplement, Olin will authorize agents,
underwriters or dealers to solicit offers by certain specified institutions to
purchase Offered Securities from Olin at the public offering price set forth in
the Prospectus Supplement pursuant to delayed delivery contracts providing for
payment and delivery on a specified date in the future. Such contracts will be
subject only to those conditions set forth in the Prospectus Supplement and the
Prospectus Supplement will set forth the commission payable for solicitation of
such contracts.
 
     Agents and underwriters may be entitled under agreements entered into with
Olin to indemnification by Olin against certain civil liabilities, including
liabilities under the Securities Act, or to contribution with respect to
payments which the agents or underwriters may be required to make in respect
thereof. Agents and underwriters may be customers of, engage in transactions
with or perform services for Olin in the ordinary course of business.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Virginia Stock Corporation Act permits, and Olin's By-Laws require,
indemnification of Olin's directors, officers and employees in a variety of
circumstances. Under Sections 13.1-697 and 13.1-704 of the Virginia Stock
Corporation Act, a Virginia corporation generally is authorized to indemnify its
directors, officers and employees in civil or criminal actions if such persons
acted in good faith and believed their conduct to be in the best interests of
the corporation and, in the case of criminal actions, had no reasonable cause to
believe that their conduct was unlawful. Olin's By-Laws require indemnification
of directors, officers and employees with respect to certain liabilities,
expenses, and other amounts imposed upon such persons by reason of having been
directors, officers or employees if such persons acted in good faith and
believed that their conduct was in the best interests of Olin or related entity.
Also, Section 13.1-692.1 of the Virginia Stock Corporation Act permits a
Virginia corporation to limit or totally eliminate the liability of a director
or officer in a shareholder or derivative proceeding.
 
     Directors and officers of Olin are insured, subject to policy limits and
certain exclusions and limitations and to the extent not otherwise indemnified
by Olin, against loss (including expenses incurred in the defense of actions,
suits and proceedings in connection therewith) arising from any error,
misstatement, misleading statement, omission or other act made or performed in
their capacity as directors and officers. The policies also reimburse Olin for
liability incurred in the indemnification of its directors and officers under
common or statutory laws or the By-Laws, subject to the terms, conditions and
exclusions of the policy. In addition, directors and officers and other
employees of Olin who may be "fiduciaries" as that term is used in the Employee
Retirement Income Security Act of 1974, are insured with respect to liabilities
under such Act.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) to include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933, as amended (the "Securities Act") unless the
        information required to be included in such post-effective amendment is
        contained in periodic reports filed by the Registrant pursuant to
        Section 13 or Section 15(d) of the Securities Exchange Act that are
        incorporated by reference in the registration statement;
 
             (ii) to reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement unless the information required to be
        included in such post-effective amendment is contained in periodic
        reports filed by the Registrant pursuant to Section 13 or Section 15(d)
        of the Securities Exchange Act that are incorporated by reference in the
        registration statement; and
 
             (iii) to include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any
 
                                      II-3
<PAGE>   51
 
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Act.

[Names and addresses of other Agents]

- -------------------------------------

Dear Sirs:


          Olin Corporation, a Virginia corporation (the "Company"), confirms
its agreement with each of you with respect to the issue and sale from time to
time by the Company of its Medium-Term Notes, Series A, due from 9 months to 40
years from date of issue (the "Securities") in an aggregate initial offering
price of up to $[300,000,000] (or the equivalent thereof in one or more foreign
currencies or composite currencies), as such amount shall be reduced by the
aggregate initial offering price of any other debt securities issued by the
Company, whether within or without the United States ("Other Securities")
pursuant to the Registration Statements referred to below, and agrees with each
of you (individually, an "Agent", and collectively, the "Agents", which term
shall include any additional agents appointed pursuant to Section 13 hereof) as
set forth in this Agreement.  The Securities will be issued under an indenture
dated as of June 15, 1992, as supplemented (the "Indenture") between the
Company and Chemical Bank, as Trustee (the "Trustee").  The Securities shall
have the maturities, interest rates, redemption provisions, if any, and other
terms set forth in the Prospectus referred to
<PAGE>   2
                                                                               2

below as it may be amended or supplemented from time to time.  The Securities
will be issued, and the terms and rights thereof established, from time to time
by the Company in accordance with the Indenture.

          On the basis of the representations and warranties herein contained,
but subject to the terms and conditions stated herein and to the reservation by
the Company of the right to sell Securities directly to investors on its own
behalf, the Company hereby (i) appoints the Agents as nonexclusive agents of
the Company for the purpose of soliciting and receiving offers to purchase
Securities from the Company by others pursuant to Section 2(a) hereof and (ii)
agrees that, except as otherwise contemplated herein, whenever it determines to
sell Securities directly to any Agent as principal, it will enter into a
separate agreement (each such agreement a "Terms Agreement"), substantially in
the form of Exhibit A hereto, relating to such sale in accordance with Section
2(b) hereof.

          The Company has prepared and filed Registration Statements on Form
S-3 (No. 33-4479 and 33-    ) in respect of the Securities with the Securities
and Exchange Commission (the "Commission") in accordance with the provisions of
the Securities Act of 1933, as amended, and the rules and regulations of the
Commission thereunder (collectively, the "Securities Act").  Registration
Statement No. 33----- includes a form of prospectus that, pursuant to Rule 429
under the Securities Act, also relates to debt securities previously registered
under Registration Statement No. 33-4479.  The Company also has filed with, or
proposes to file with, the Commission pursuant to Rule 424 under the Securities
Act supplements to the prospectus included in the Registration Statements that
will describe certain terms of the Securities.  The aforesaid Registration
Statements, including the exhibits thereto, as amended to the Commencement Date
(as hereinafter defined) are hereinafter referred to as the "Registration
Statement" and the prospectus in the form in which it appears in each
Registration Statement is hereinafter referred to as the "Basic Prospectus".
The Basic Prospectus as supplemented by the prospectus supplement or
supplements (each a "Prospectus Supplement") specifically relating to the
Securities in the form filed with, or transmitted for filing to, the Commission
pursuant to Rule 424 under the Securities Act is hereinafter referred to as the
"Prospectus".  Any reference in this Agreement to the Registration Statement,
the Basic Prospectus, any preliminary form of Prospectus (a
<PAGE>   3
                                                                               3


"preliminary prospectus") previously filed with the Commission pursuant to Rule
424 or the Prospectus shall be deemed to refer to and include the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the
Securities Act which were filed under the Securities Exchange Act of 1934, as
amended, and the rules and regulations of the Commission thereunder
(collectively, the "Exchange Act") on or before the date of this Agreement or
the date of the Basic Prospectus, any preliminary prospectus or the Prospectus,
as the case may be; and any reference to "amend", "amendment" or "supplement"
with respect to the Registration Statement, the Basic Prospectus, any
preliminary prospectus or the Prospectus, including any supplement to the
Prospectus that sets forth only the terms of a particular issue of the
Securities (a "Pricing Supplement"), shall be deemed to refer to and include
any documents filed under the Exchange Act after the date of this Agreement, or
the date of the Basic Prospectus, any preliminary prospectus or the Prospectus,
as the case may be, which are deemed to be incorporated by reference therein.

          1.  Representations.  The Company represents and warrants to, and
agrees with, each Agent as of the Commencement Date (as hereinafter defined),
as of each date on which the Company accepts an offer to purchase Securities
(including any purchase by an Agent as principal pursuant to a Terms Agreement
or otherwise), and as of each date the Company issues and sells Securities as
follows (it being understood that such representations and warranties shall be
deemed to relate to the Registration Statement, the Basic Prospectus and the
Prospectus, each as amended or supplemented to each such date):

          (a)  The Registration Statement has been declared effective by the
     Commission under the Securities Act; to the knowledge of the Company, no
     stop order suspending the effectiveness of the Registration Statement has
     been issued and no proceeding for that purpose has been instituted or
     threatened by the Commission; and the Registration Statement and
     Prospectus (as amended or supplemented if the Company shall have furnished
     any amendments or supplements thereto) comply, or will comply, as the case
     may be, in all material respects with the Securities Act, the Exchange Act
     and the Trust Indenture Act of 1939, as amended, and the rules and
     regulations of the Commission thereunder (collectively, the "Trust
<PAGE>   4
                                                                               4


     Indenture Act"), and do not and will not, as of the applicable effective
     date as to the Registration Statement and any amendment or supplement
     thereto and as of the date of the Prospectus and any amendment or
     supplement thereto, contain any untrue statement of a material fact or
     omit to state any material fact required to be stated therein or necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading; except that the foregoing
     representations and warranties shall not apply to statements or omissions
     in the Registration Statement or the Prospectus made in reliance upon and
     in conformity with information relating to any Agent furnished to the
     Company in writing by such Agent expressly for use therein;

          (b)  The financial statements, and the related notes thereto,
     included or incorporated by reference in the Registration Statement and
     the Prospectus present fairly the consolidated financial position of the
     Company and its consolidated subsidiaries as of the dates indicated and
     the results of their operations and the changes in their consolidated cash
     flows for the periods specified; said financial statements have been
     prepared in conformity with generally accepted accounting principles
     applied on a consistent basis, and the supporting schedules included or
     incorporated by reference in the Registration Statement present fairly the
     information required to be stated therein; and the pro forma financial
     information, and the related notes thereto, if any, included or
     incorporated by reference in the Registration Statement and the Prospectus
     has been prepared in accordance with the applicable requirements of the
     Securities Act and the Exchange Act, as applicable;

          (c)  Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, there has not been any
     material adverse change or any development which is likely, in the
     reasonable judgment of the Company, to result in a material adverse change
     in or affecting the financial condition or results of operations of the
     Company and its subsidiaries, taken as a whole, otherwise than as set
     forth or contemplated in the Prospectus;

          (d)  The Securities have been duly authorized, and, when issued and
     delivered in accordance with the
<PAGE>   5
                                                                               5


     Indenture and delivered to and paid for by the purchasers thereof in
     accordance with this Agreement and any applicable Terms Agreement, will
     have been duly executed, issued and delivered by the Company and will
     constitute valid and binding obligations of the Company entitled to the
     benefits provided by the Indenture; the Indenture has been duly
     authorized, executed and delivered by the Company and qualified under the
     Trust Indenture Act and constitutes a valid and binding instrument
     enforceable in accordance with its terms, subject, as to enforcement, to
     bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium
     and other laws of general applicability relating to or affecting
     creditors' rights generally and to general equity principles; and the
     Indenture conforms, and the Securities of any particular issuance of
     Securities will conform, to the descriptions thereof in the Prospectus as
     amended or supplemented to relate to such issuance of Securities; and

          (e)  Immediately after any sale of Securities by the Company
     hereunder or under any Terms Agreement, the aggregate amount of Securities
     which shall have been issued and sold by the Company hereunder or under
     any Terms Agreement and of any debt securities of the Company (other than
     such Securities) that shall have been issued and sold pursuant to the
     Registration Statements will not exceed the amount of debt securities
     registered under the Registration Statements.

          2.  Solicitations as Agent; Purchases as Principal.  (a)
Solicitations as Agent.  On the basis of the representations and warranties
herein contained, but subject to the terms and conditions herein set forth,
each of the Agents hereby severally and not jointly agrees, as agent of the
Company, to use its best efforts to solicit offers to purchase the Securities
from the Company upon the terms and conditions set forth in the Prospectus as
amended or supplemented from time to time.  So long as this Agreement shall be
in effect the Issuer shall not solicit offers to purchase Securities through
any agent without amending this Agreement to appoint such agent an additional
Agent hereunder on the same terms and conditions as provided herein for the
Agents and without giving the Agents prior notice of such appointment.  The
Issuer may accept offers to purchase Notes through an agent other than an
Agent, provided that (i) the Issuer shall not have solicited such
<PAGE>   6
                                                                               6


offers, (ii) the Issuer and such agent shall have executed an agreement with
respect to such purchases having terms and conditions (including, without
limitation, commission rates) with respect to such purchases substantially the
same as the terms and conditions that would apply to such purchases under this
Agreement as if such agent were an Agent (which may be accomplished by
incorporating by reference in such agreement the terms and conditions of this
Agreement) and (iii) the Company shall provide the Agents with a copy of such
agreement promptly following the execution thereof.

          The Company reserves the right, in its sole discretion, to instruct
the Agents to suspend at any time, for any period of time or permanently, the
solicitation of offers to purchase Securities.  Upon receipt of at least one
business day's prior notice from the Company, each Agent will suspend
solicitation of offers to purchase Securities from the Company until such time
as the Company has advised such Agent or Agents that such solicitation may be
resumed.  During the period of time that such solicitation is suspended, the
Company shall not be required to deliver any opinions, letters or certificates
in accordance with Sections 4(h), 4(i) and 4(j); provided that if the
Registration Statement or Prospectus is amended or supplemented during the
period of suspension (other than by an amendment or supplement providing solely
for a change in the interest rates, redemption provisions, amortization
schedules or maturities offered for the Securities or for a change that the
Agents deem to be immaterial), no Agent shall be required to resume soliciting
offers to purchase Securities until the Company has delivered such opinions,
letters and certificates as such Agent may reasonably request.

          The Company agrees to pay each Agent at the time payment is received
for the Security, as consideration for the sale of such Security resulting from
a solicitation made or an offer to purchase received by such Agent, a
commission in the form of a discount from the purchase price of such

Security in an amount equal to the following applicable percentage of the
principal amount of such Security sold or such other rates as may from time to
time be agreed upon:

          The Agents are authorized to solicit offers to purchase Securities
only in the principal amount of $100,000 (or, in the case of Securities not
denominated in U.S. dollars, the equivalent thereof in the applicable foreign
currency or composite currency, rounded down to the nearest 1,000 units of such
foreign currency or composite currency) or any amount in excess thereof which
is an integral multiple of $1,000 (or, in the case of Securities not
denominated in U.S. dollars, 1,000 units of such foreign currency or composite
currency).  Each Agent shall communicate to the Company, orally or in writing,
each offer to purchase Securities received by such Agent as agent that in its
judgment should be considered by the Company.  The Company shall have the sole
right to accept offers to purchase the Securities and may reject any such offer
in whole or in part.  Each Agent shall have the right, in its sole discretion,
to reject any offer to purchase Securities, as a whole or in part, that it
considers to be unacceptable and any such rejection shall not be deemed a
breach of its agreements herein contained.  The procedural details relating to
the issue and delivery of Securities sold by an Agent as agent and the payment
therefor are set forth in the Administrative Procedures (as hereinafter
defined).

                                                                               8


     (b)  Purchase as Principal.  Each sale of Securities to any Agent as
principal shall be made in accordance with the terms of this Agreement and
(unless such Agent shall otherwise agree) a Terms Agreement which will provide
for the sale of such Securities to, and the purchase thereof by, such Agent.  A
Terms Agreement will be substantially in the form of Exhibit A hereto but may
be oral, and if oral, must be confirmed promptly in writing (which writing may
include facsimile transmission).  Any oral Terms Agreement shall be deemed to
contain the terms and provisions contained in Exhibit A hereto.  The Terms
Agreement may also specify certain provisions relating to the reoffering of
such Securities by such Agent.  The commitment of any Agent to purchase
Securities as principal, whether pursuant to any Terms Agreement or otherwise,
shall be deemed to have been made on the basis of the representations and
warranties of the Company herein contained and shall be subject to the terms
and conditions herein and in the applicable Terms Agreement set forth.  Each
agreement by an Agent to purchase Securities as principal (pursuant to a Terms
Agreement or otherwise) shall specify the principal amount of Securities to be
purchased by such Agent pursuant thereto, the price to be paid to the Company
for such Securities, the maturity date of such Securities, the interest rate or
interest rate basis, if any, applicable to such Securities, any other terms of
such Securities, the time and date and place of delivery of and payment for
such Securities (the time and date of any and each such delivery and payment,
the "Time of Delivery"), any provisions relating to rights of, and default by,
underwriters acting together with such Agent in the reoffering of Securities,
and any requirements for opinions of counsel, accountants' letters and
officer's certificates pursuant to Section 4 hereof.  Unless otherwise
specified in a Terms Agreement, the procedural details relating to the issue
and delivery of Securities purchased by an Agent as principal and the payment
therefore shall be as set forth in the Administrative Procedures.

     (c)  Obligations Several.  The Company acknowledges that the obligations
of the Agents are several and not joint and, subject to the provisions of this
Section 2, each Agent shall have complete discretion as to the manner in which
it solicits purchasers for the Securities and as to the identity thereof.

     (d)  Administrative Procedures.  Each of the Agents and the Company agree
to perform their respective duties and obligations specifically provided to be
performed in the

Securities is commenced or the first date on which the Company accepts an offer
by any Agent to purchase Securities as principal (such time and date being
referred to herein as the "Commencement Date").

          4.  Covenants of the Company.  The Company covenants and agrees with
each Agent:

          (a)(i)  The Company will advise each Agent promptly of any proposal
     to amend or supplement the Registration Statement or the Prospectus
     (except for (A) periodic or current reports and proxy or information
     statements filed under the Exchange Act, (B) a supplement relating to any
     offering of Securities providing solely for the specification of or a
     change in the maturity dates, interest rates, issuance prices or other
     similar terms of any Securities or (C) a supplement relating to an
     offering of securities other than the Securities)  and will afford the
     Agents a reasonable opportunity to comment on any such proposed amendment
     or supplement; (ii) subject to the foregoing clause (i), promptly to cause
     each Prospectus Supplement to be filed with or transmitted for filing to
     the Commission in accordance with Rule 424(b) under the Securities Act and
     to prepare, with respect to any Securities to be sold through or to such
     Agent pursuant to this Agreement, a Pricing Supplement with respect to
     such Securities in a form previously approved by such Agent and to file
     such Pricing Supplement in accordance with Rule 424(b) under the
     Securities Act; and (iii) promptly to file all reports and any definitive
     proxy or information statements required to be filed by the Company with
     the Commission pursuant to
<PAGE>   10
                                                                              10


     Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the
     delivery of a prospectus is required in connection with the offering or
     sale of the Securities.  The Company will promptly advise each Agent (W)
     of any final unresolved disagreement with the Commission of any issue
     materially affecting the financial statements of the Company included or
     incorporated by reference in the Registration Statements or the Prospectus
     occurring at any time when a prospectus relating to the Securities is
     required to be delivered under the Securities Act, (X) of the filing of
     any amendment or supplement to the Basic Prospectus (other than amendments
     or supplements excepted by the foregoing clause (i)) or any amendment to
     the Registration Statement and of the effectiveness of any such amendment
     to the Registration Statement, (Y) of the issuance by the Commission of
     any stop order suspending the effectiveness of the Registration Statement
     or any order preventing or suspending the use of any prospectus relating
     to the Securities or the initiation or threatening of any proceeding for
     that purpose, or of any request by the Commission for any amendment or
     supplement of the Registration Statement or Prospectus or for additional
     information; and (Z) of the receipt by the Company of any notification
     with respect to any suspension of the qualification of the Securities for
     offering or sale in any jurisdiction, of the initiation or threatening of
     any proceeding for any such purpose.  The Company agrees to use its best
     efforts to prevent the issuance of any such stop order or of any such
     order preventing or suspending the use of any such prospectus or of any
     notification suspending any such qualification and, if issued, to use
     promptly its best efforts to obtain withdrawal thereof as soon as
     possible.  If the Basic Prospectus is amended or supplemented as a result
     of the filing under the Exchange Act of any document incorporated by
     reference in the Prospectus, no Agent shall be obligated to solicit offers
     to purchase Securities so long as it is not reasonably satisfied with such
     document.

          (b)  To endeavor to qualify the Securities for offer and sale under
     the securities or Blue Sky laws of such jurisdictions as the Agents shall
     reasonably request and to continue such qualification in effect so long as
     reasonably required in connection with the distribution of the Securities;
     provided that the
<PAGE>   11
                                                                              11


     Company shall not be required to file a general consent to service of
     process in any jurisdiction.

          (c)  To furnish each Agent and counsel to the Agents, at the expense
     of the Company, a copy of the Registration Statement (as originally filed)
     and each amendment thereto, in each case including exhibits and documents
     incorporated by reference therein and, during the period mentioned in
     paragraph (d) below, to furnish each Agent as many copies of the
     Prospectus (including all amendments and supplements thereto) and
     documents incorporated by reference therein as such Agent may reasonably
     request.

          (d)  If at any time when a prospectus relating to the Securities is
     required to be delivered under the Securities Act, any event shall occur
     as a result of which the Prospectus, as then amended or supplemented,
     would include an untrue statement of a material fact or omit to state any
     material fact necessary in order to make the statements therein, in the
     light of the circumstances when such Prospectus is delivered to a
     purchaser, not misleading, or, if in the opinion of the Agents or the
     Company, it is necessary at any time to amend or supplement the Prospectus
     to comply with law, to immediately notify the Agents by telephone (with
     confirmation in writing) and request each Agent (i) in its capacity as
     agent of the Company, to suspend solicitation of offers to purchase
     Securities from the Company (and, if so notified, such Agent shall cease
     such solicitations and cease using the Prospectus as soon as practicable,
     but in any event not later than one business day later); and (ii) to cease
     sales of any Securities such Agent may then own as principal.  If the
     Company shall decide to amend or supplement the Registration Statement or
     the Prospectus, as then amended or supplemented, it shall so advise each
     Agent promptly by telephone (with confirmation in writing) and, at its
     expense, shall prepare and cause to be filed promptly with the Commission
     an amendment or supplement to the Registration Statement or the
     Prospectus, as then amended or supplemented, that will correct such
     statement or omission or effect such compliance and will supply such
     amended or supplemented Prospectus to the Agents in such quantities as
     they may reasonably request.  If any such amendment or supplement and any
     documents, opinions, letters and certificates furnished to the Agents
     pursuant to
<PAGE>   12
                                                                              12


     Sections 4(e), 4(h), 4(i) and 4(j) in connection with the preparation and
     filing of such amendment or supplement are satisfactory in all respects to
     the Agents, upon the filing with the Commission of such amendment or
     supplement to the Prospectus or upon the effectiveness of an amendment to
     the Registration Statement, the Agents will resume the solicitation of
     offers to purchase Securities hereunder.  Notwithstanding any other
     provision of this Section 4(d), until the distribution of any Securities
     any Agent may own as principal has been completed or such Agent is
     otherwise required to deliver a prospectus in respect of a transaction in
     the Securities, if any event described in this Section 4(d) occurs the
     Company will, at its expense, promptly prepare and file with the
     Commission an amendment or supplement, satisfactory in all respects to
     such Agent, that will correct such statement or omission or effect such
     compliance, will supply such amended or supplemented Prospectus to such
     Agent in such quantities as such Agent may reasonably request and shall
     furnish to such Agent such documents, certificates, opinions and letters
     as are set forth in Sections 4(e), 4(h), 4(i) and 4(j) as it may
     reasonably request in connection with the preparation and filing of such
     amendment or supplement.

          (e)  To furnish to the Agents during the term of this Agreement such
     relevant documents and certificates of officers of the Company relating to
     the business, operations and affairs of the Company, the Registration
     Statement, the Basic Prospectus, any amendments or supplements thereto,
     the Indenture, the Securities, this Agreement, the Administrative
     Procedures, any applicable Terms Agreement and the performance by the
     Company of its obligations hereunder or thereunder as the Agents may from
     time to time reasonably request and shall notify the Agents promptly in
     writing of (i) any downgrading in the rating accorded any of securities
     of, or guaranteed by, the Company by any "nationally recognized
     statistical rating organization", as such term is defined for purposes of
     Rule 436(g)(2) under the Securities Act or (ii) any public announcement by
     any such rating organization that it has under surveillance or review,
     with possible negative implications, its rating of any of the debt
     securities of the Company.

                                                                              13


          (f)  To make generally available to its security holders and to such
     Agent as soon as practicable earnings statements which shall satisfy the
     provisions of Section 11(a) of the Securities Act and Rule 158 of the
     Commission promulgated thereunder covering periods of at least twelve
     months beginning in each case with the first fiscal quarter of the Company
     occurring after the "effective date" (as defined in Rule 158) of the
     Registration Statement with respect to each sale of Securities.

          (g)  So long as any Securities are outstanding, to furnish to such
     Agent copies of all reports or other communications (financial or other)
     furnished to holders of Securities and copies of any reports and financial
     statements furnished to or filed with the Commission or any national
     securities exchange on which any class of securities of the Company is
     listed.

          (h)  Each time the Company files with the Commission an Annual Report
     on Form 10-K, a Quarterly Report on Form 10-Q, a Current Report on Form
     8-K or an Amendment to an Application or Report pursuant to Rule 12b-15
     under the Exchange Act, the Company will deliver or cause to be delivered
     promptly to each of the Agents a certificate of the Company, signed by the
     Treasurer, the Assistant Treasurer or an executive officer of the Company
     reasonably acceptable to the Agents, dated the date of filing of such
     Report or Amendment in form reasonably satisfactory to you, of the same
     tenor as the certificate referred to in Section 6(e) but modified to
     relate to the last day of the fiscal quarter for which financial
     statements of the Company were last filed with the Commission (or the date
     of the matter(s) described in the Form 8-K, if applicable) and to the
     Registration Statement and the Prospectus as amended and supplemented to
     the date of such certificate.

          (i)  Each time the Company files with the Commission an Amendment to
     the Registration Statement, an Annual Report on Form 10-K, a Quarterly
     Report on Form 10-Q, a Current Report on Form 8-K or an Amendment to an
     Application or Report pursuant to Rule 12b-15 under the Exchange Act
     (except that, in the case of an Amendment to the Registration Statement, a
     Quarterly Report on Form 10-Q or a Current Report on Form 8-K, the opinion
     referred to below shall only be furnished
<PAGE>   14
                                                                              14


     if, in the reasonable judgment of any Agent, the financial statements or
     other information set forth in such Form 10-Q or Form 8-K are of such a
     nature that an opinion of counsel should be furnished) the Company shall
     furnish  or cause to be furnished promptly to each of you a written
     opinion of the General Counsel or an Associate General Counsel of the
     Company, dated the date of the effectiveness of such amendment or the date
     of the filing of such supplement, in form satisfactory to each of you, of
     the same tenor as the opinion referred to in Section 6(b) but modified to
     relate to the last day of the fiscal quarter for which financial
     statements of the Company were last filed with the Commission (or to the
     date of the matter(s) described in the Form 8-K, if applicable) and to the
     Registration Statement and the Prospectus as amended and supplemented to
     the date of such opinion or, in lieu of such opinion, counsel last
     furnishing such an opinion to you may furnish each of you with a letter to
     the effect that you may rely on such last opinion to the same extent as
     through it were dated the date of such letter authorizing reliance (except
     that statements in such last opinion will be deemed to relate to the
     Registration Statement and the Prospectus as amended and supplemented to
     the date of such letter authorizing reliance).

          (j)  Each time the Company files with the Commission an Amendment to
     the Registration Statement, an Annual Report on Form 10-K, a Quarterly
     Report on Form 10-Q, a Current Report on Form 8-K or an amendment to an
     Application or Report pursuant to Rule 12b-15 under the Exchange Act
     (except that, in the case of an Amendment to the Registration Statement, a
     Quarterly Report on Form 10-Q or a Current Report on Form 8-K, the letter
     referred to below shall only be furnished if, in the reasonable judgment
     of any of you, the matter(s) set forth in such Form 10-Q or Form 8-K are
     of such a nature that a letter of independent auditors should be
     furnished), the Company shall cause its independent auditors promptly to
     furnish each of you a letter, dated the date of filing such Report or
     Amendment, in form satisfactory to each of you, of the same tenor as the
     letter referred to in Section 6(d) with such changes as may be necessary
     to reflect the amended and supplemental financial information included in
     the Report or Amendment, as amended to the date of such letter; provided,
     however, that, if a Report or
<PAGE>   15
                                                                              15


     Amendment is filed solely to include or incorporate by reference financial
     information as of and for a fiscal quarter, the Company's independent
     auditors may limit the scope of such letter, which shall be satisfactory
     in form to each of you, to the unaudited financial statements, the related
     "Management's Discussion and Analysis of Financial Condition and Results
     of Operations" and any other information of an accounting, financial or
     statistical nature included in such Report or Amendment (any such letter
     limited in scope as aforesaid being hereinafter referred to as a "Routine
     Quarterly Letter"), unless, in the reasonable judgment of any of you, such
     letter should cover other information or changes in specified financial
     statement line items; provided further, however, each Agent may waive
     delivery, with respect to itself, of such Routine Quarterly Letter.
     Notwithstanding Section 6(d), the Company's independent auditors need not
     read the minutes of the stockholders', directors' and executive, finance,
     and audit committee meetings of any subsidiary of the Company which did
     not constitute a "significant subsidiary" within the meaning of Regulation
     S-X as of the end of the most recently completed fiscal year as part of
     the basis for the statements made in any Routine Quarterly Letter.

          5.  Costs and Expenses.  The Company covenants and agrees with each
Agent that the Company will, whether or not any sale of Securities is
consummated, pay all the following reasonable costs and expenses:  (i) incident
to the preparation, issuance, execution, authentication and delivery of the
Securities, including any expenses of the Trustee, (ii) incident to the
preparation, printing and filing under the Securities Act of the Registration
Statement, the Prospectus and any preliminary prospectus (including in each
case all exhibits, amendments and supplements thereto), (iii) incurred in
connection with the registration or qualification and determination of
eligibility for investment of the Securities under the laws of such
jurisdictions as the Agents (or in connection with any Terms Agreement, the
applicable Agent) may designate, (iv) in connection with the printing
(including word processing and duplication costs) and delivery of this
Agreement, the Indenture, any Blue Sky Memoranda and any Legal Investment
Survey and the furnishing to the Agents and dealers of copies of the
Registration Statement and the Prospectus, including mailing and shipping, as
herein provided, (v) payable to rating agencies in connection with
<PAGE>   16
                                                                              16


the rating of the Securities, (vi) the reasonable fees and disbursements of
counsel for the Agents incurred in connection with the execution of this
Agreement, including any opinions to be rendered by such counsel hereunder and
(vii) any advertising expenses incurred by the Agents with the prior approval
of the Company.

          6.  Conditions.  The obligation of any Agent, as agent of the
Company, at any time ("Solicitation Time") to solicit offers to purchase the
Securities, the obligation of any Agent to purchase Securities as principal
pursuant to any Terms Agreement or otherwise, shall in each case be subject (1)
to the condition that all representations and warranties of the Company herein
and all statements of officers of the Company made in any certificate furnished
pursuant to the provisions hereof are true and correct in all material respects
(i) in the case of an Agent's obligation to solicit offers to purchase
Securities, at and as of such Solicitation Time and (ii) in the case of any
Agent's obligation to purchase Securities, at and as of the time the Company
accepts the offer to purchase such Securities and, as the case may be, at and
as of the related Time of Delivery or time of purchase; (2) to the condition
that at or prior to such Solicitation Time, time of acceptance, Time of
Delivery or time of purchase, as the case may be, the Company shall have
complied with all its agreements and all conditions on its part to be performed
or satisfied hereunder; and (3) to the following additional conditions when and
as specified:

          (a)  Prior to such Solicitation Time or corresponding Time of
     Delivery or time of purchase, as the case may be:

               (i) the Prospectus as amended or supplemented (including, if
          applicable, the Pricing Supplement) with respect to such Securities
          shall have been filed with the Commission pursuant to Rule 424(b)
          under the Securities Act within the applicable time period prescribed
          for such filing by the rules and regulations under the Securities
          Act; no stop order suspending the effectiveness of the Registration
          Statement shall be in effect and no proceeding for that purpose shall
          have been initiated or threatened by the Commission; and all requests
          for additional information on the part of the Commission shall have
          been complied with to the reasonable satisfaction of such Agent;
<PAGE>   17
                                                                              17



              (ii)  there shall not have occurred any downgrading, nor shall
          any "nationally recognized statistical rating organization", as such
          term is defined for purposes of Rule 436(g)(2) under the Securities
          Act, have publicly announced that it has under surveillance or
          review, with possible negative implications, its rating of any of the
          debt securities of the Company;

             (iii)  there shall not have been any material adverse change or
          any development which will result in a material adverse change in or
          affecting the financial condition or results of operations of the
          Company and its subsidiaries, taken as a whole, otherwise than as set
          forth or contemplated in the Prospectus, as amended or supplemented
          to such Solicitation Time or at the time such offer to purchase was
          made, the effect of which, in the reasonable judgment of the
          applicable Agent, makes it impracticable or inadvisable to proceed
          with the proposed public offering or the delivery of the Securities
          in the form and the manner contemplated in the Prospectus; and

              (iv)(A)  trading generally shall not have been suspended or
          materially limited on or by, as the case may be, the New York Stock
          Exchange or the National Association of Securities Dealers, Inc.
          ("NASD"), (B) trading of any securities of or guaranteed by the
          Company shall not have been suspended on any exchange or in any
          over-the-counter market, (C) a general moratorium on commercial
          banking activities in New York shall not have been declared by either
          Federal or New York State authorities, or (D) there shall not have
          occurred any outbreak or escalation of hostilities or any change in
          financial markets or any calamity or crisis that, in the judgment of
          such Agent or Agents or of such other purchaser, is material and
          adverse and which in the judgment of such Agent or Agents or of such
          other purchaser makes it impracticable to market the Securities on
          the terms and in the manner contemplated in the Prospectus as amended
          or supplemented at the Solicitation Time or at the time such offer to
          purchase was made.

          (b)  On the Commencement Date, a General Counsel or an Associate
     General Counsel of the Company shall have furnished to the relevant Agent
     or Agents his written opinion, dated the Commencement Date, in form and
     substance satisfactory to such Agent or Agents, to the effect that:

               (i)  the Company has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the
          jurisdiction of its incorporation, with corporate power to own its
          properties and conduct its business as described in the Prospectus;

          corporation for the transaction of business and is in good standing
          under the laws of each other jurisdiction in which it owns or leases

          qualifications, other than where the failure to be so qualified or in
          good standing would not have a material adverse effect on the Company
          and its subsidiary taken as a whole;

             (iii)  each subsidiary of the Company (any such subsidiary being
          identified in such opinion) which constituted a "significant
          subsidiary" within the meaning of Regulation S-X as of the end of the
          most recently completed fiscal year has been duly incorporated and is
          validly existing as a corporation under the laws of its jurisdiction
          of incorporation with corporate power to own its properties and
          conduct its business as described in the Prospectus and has been duly
          qualified as a foreign corporation for the transaction of business
          and is in good standing under the laws of each jurisdiction in which
          it owns or leases properties, or conducts any business, so as to
          require such qualification, other than where the failure to be so
          qualified and in good standing would not have a material adverse
          effect on the Company and its subsidiaries taken as a whole;

               (iv)  this Agreement has been, and any applicable Terms
          Agreement will be, duly authorized, executed and delivered by the
          Company, and is, or will be, valid and binding agreements except as

          hereunder and thereunder may be limited by applicable law;

                (v)  the Securities have been duly authorized and, when
          executed and authenticated in accordance with the terms of the
          Indenture and delivered to and paid for by any purchaser of
          Securities sold through an Agent as agent or any Agent as principal
          pursuant to any Terms Agreement or other agreement, will constitute
          valid and binding obligations of the Company entitled to the benefits
          provided by the Indenture and the Indenture and the Securities
          conform to the descriptions thereof in the Prospectus as amended or
          supplemented;

             (vi)  the Indenture has been duly authorized, executed and
          delivered by the Company and constitutes a valid and binding
          instrument of the Company enforceable against the Company in
          accordance with its terms, subject, as to enforcement, to bankruptcy,
          insolvency, reorganization, fraudulent transfer, moratorium and other
          laws of general applicability relating to or affecting creditors'
          rights generally and to general equity principles; and the Indenture
          has been duly qualified under the Trust Indenture Act;

            (vii)  the issue and sale of the Securities and the performance by
          the Company of its obligations under the Securities, the Indenture
          and this Agreement and the consummation of the transactions herein
          and therein contemplated will not conflict with or result in a breach
          of any of the terms or provisions of, or constitute a default under,
          any indenture or material mortgage, deed of trust, loan agreement or
          other agreement or instrument to which the Company or any of its
          subsidiaries is a party or by which the Company or any of its
          subsidiaries is bound or to which any of the material property or
          assets of the Company or any of its subsidiaries is subject, nor will
          any such action result in any violation of the provisions of the
          Restated Articles of Incorporation or the By-Laws of the Company or
          any order, rule or regulation of any court or governmental agency or
          body having jurisdiction over the Company, its
<PAGE>   20
                                                                              20


          subsidiaries or any of their respective properties;

              (viii)  no consent, approval, authorization, order, registration
          or qualification of or with any court or governmental agency or body
          is required for the issue and sale of the Securities or the
          consummation of the other transactions contemplated by this Agreement
          or the Indenture, except such consents, approvals, authorizations,
          registrations or qualifications as have been obtained under the
          Securities Act and the Trust Indenture Act and as may be required
          under state securities or Blue Sky laws in connection offers and
          sales of the Securities from the Company and with purchases of
          Securities; and

               (ix)  the Registration Statement has become effective under the
          Securities Act, and, to the best knowledge of such counsel, no stop
          order suspending the effectiveness of the Registration Statement or
          of any part thereof has been issued and no proceedings for that
          purpose have been instituted or are pending or contemplated under the
          Securities Act, and the Registration Statement, as of its effective
          date, and the Prospectus, as of the Commencement Date, and any
          amendment or supplement thereto, as of its date, appear on their face
          to be appropriately responsive in all material respects with the
          requirements of the Securities Act, the Exchange Act and the Trust
          Indenture Act and the Rules and Regulations; such counsel has no
          reason to believe that the Registration Statement, as of its
          effective date, or the Prospectus, as of the Commencement Date, or
          any such amendment or supplement, as of its date, contained any
          untrue statement of a material fact or omitted to state any material
          fact required to be stated therein or necessary to make the
          statements therein not misleading or contains any untrue statement of
          a material fact or omits to state any material fact required to be
          stated therein or necessary to make the statements therein, in light
          of the circumstances under which they were made, not misleading; the
          descriptions in the Registration Statement and the Prospectus of
          legal and governmental proceedings and contracts and other
<PAGE>   21
                                                                              21


          documents fairly present the information required to be shown; and 
          such counsel do not know of any legal or governmental proceedings 
          required to be described in the Prospectus which are not described as 
          required or of any contracts or documents of a character required to 
          be described in the Registration Statement which are not described 
          and filed as required; provided, however, that the foregoing opinions 
          shall not extend to information under the heading United States 
          Federal Income Taxation, insofar as such information constitutes a 
          summary of legal matters.

In rendering such opinions, such counsel may rely (A) as to matters involving
the application of the laws of the Commonwealth of Virginia, to the extent such
counsel deems proper and to the extent specified in such opinion, if at all,
upon an opinion or opinions (in form and substance reasonably satisfactory to
the Agents' counsel) of other counsel reasonably acceptable to the Agents'
counsel, familiar with the applicable laws; (B) as to matters included in
paragraphs (v), (vi) and (ix) of this Section 6(b), upon the opinion of
Cravath, Swaine & Moore, counsel to the Company and (C) as to matters of fact,
to the extent such counsel deems proper, on certificates of responsible
officers of the Company and certificates or other written statements of
officials of jurisdictions having custody of documents respecting the corporate
existence or good standing of the Company and any Principal Subsidiaries.  The
opinion of such counsel for the Company shall state that the opinion of any
such other counsel is in form satisfactory to such counsel and, in such
counsel's opinion, the Agents and they are justified in relying thereon.

          (c)  On the Commencement Date, Cravath, Swaine & Moore, counsel to
     the Company, shall have furnished to the relevant Agent or Agents a
     written opinion, dated the Commencement Date, in form and substance
     satisfactory to such Agent or Agents, with respect to paragraphs (v),
     (vi), (viii) and (ix) of Section 6(b) (provided, however, that with
     respect to paragraph (viii) such consents approvals, authorizations,
     orders, registrations or qualifications shall be limited to those required
     by Federal law and with respect to paragraph (ix), no exception shall be
     made as to information under the heading United States
<PAGE>   22
                                                                              22


     Federal Income Taxation, insofar as any such information constitutes a
     summary of legal matters).

          (d)  On the Commencement Date, Brown & Wood, counsel to the Agents,
     shall have furnished to the relevant Agent or Agents such opinion or
     opinions, dated the Commencement Date with respect to the validity of the
     Indenture, the Securities, the Registration Statement, the Prospectus as
     amended or supplemented and other related matters as such Agent or Agents
     may reasonably request, and in each case such counsel shall have received
     such papers and information as they may reasonably request to enable them
     to pass upon such matters.

          (e)  On the Commencement Date, the Company's independent certified
     public accountants who have certified the financial statements of the
     Company and its subsidiaries included or incorporated by reference in the
     Registration Statement and Prospectus, as then amended or supplemented,
     shall have furnished to the relevant Agent or Agents a letter, dated the
     Commencement Date, in form and substance satisfactory to such Agent or
     Agents, containing statements and information of the type ordinarily
     included in accountants' "comfort letters" to underwriters with respect to
     the financial statements and certain financial information relating to the
     Company contained in or incorporated by reference in the Registration
     Statement and the Prospectus, as then amended or supplemented.

          (f)  On the Commencement Date, the relevant Agent or Agents shall
     have received a certificate or certificates signed by an executive officer
     of the Company, dated the Commencement Date, to the effect set forth in
     Section 6(a)(i) and (ii) above and to the further effect that (1) the
     representations and warranties of the Company contained herein are true
     and correct on and as of the Commencement Date, as if made on and as of
     such date and (2) the Company has complied with all agreements and all
     conditions on its part to be performed or satisfied hereunder at or prior
     to the Commencement Date.

          (g)  On the Commencement Date the Company shall have furnished to the
     relevant Agent or Agents such
<PAGE>   23
                                                                              23


     further certificates, information and documents as such Agent or Agents may
     reasonably request.

          7.  Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless each Agent and each person, if any, who controls
such Agent within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including without limitation the legal fees and other
expenses incurred in connection with any suit, action or proceeding or any
claim asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any amendment thereof
or the Prospectus (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or any preliminary prospectus
or caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Agent furnished to the Company in writing by such Agent expressly for use
therein.

     (b)  Each Agent agrees, severally and not jointly, to indemnify and hold
harmless the Company, it directors, its officers who sign the Registration
Statement and each person who controls the Company within the meaning of
Section 15 of the Securities Act and Section 20 of the Exchange Act, to the
same extent as the foregoing indemnity from the Company to each Agent, but only
with reference to information relating to such Agent furnished to the Company
in writing by such Agent expressly for use in the Registration Statement, the
Prospectus, any amendment or supplement thereto, or any preliminary prospectus.

     (c)  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of
the two preceding paragraphs, such person (the "Indemnified Person") shall
promptly notify the person against whom such indemnity may be sought (the
"Indemnifying Person") in writing, and the Indemnifying Person, upon request of
the Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the
<PAGE>   24
                                                                              24


Indemnified Person and any others the Indemnifying Person may designate in such
proceeding and shall pay the reasonable fees and expenses of such counsel
related to such proceeding.  In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to
the contrary, (ii) the Indemnifying Person has failed within a reasonable time
to retain counsel reasonably satisfactory to the Indemnified Person or (iii)
the named parties in any such proceeding (including any impleaded parties)
include both the Indemnifying Person and the Indemnified Person and
representation of both parties by the same counsel would be inappropriate due
to actual or potential differing interests between them.  It is understood that
the Indemnifying Person shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all
Indemnified Persons, and that all such fees and expenses shall be reimbursed as
they are incurred.  Any such separate firm for the Agents and such control
persons of the Agents shall be designated in writing by J. P. Morgan Securities
Inc. or, if J. P.  Morgan Securities Inc. is not an Indemnified Party by the
Agents that are Indemnified Parties and any such separate firm for the Company,
its directors, its officers who sign the Registration Statement and such
control persons of the Company shall be designated in writing by the Company.
The Indemnifying Person shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify any Indemnified Person from and against any loss or
liability by reason of such settlement or judgment.

     (d)  If the indemnification provided for in paragraphs (a) or (b) this
Section 7 is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to herein in connection
with any offering of Securities, then each Indemnifying Person under such
paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and each Agent on the other from the offering of the Securities or
<PAGE>   25
                                                                              25


(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault
of the Company on the one hand and each Agent on the other in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations.  The
relative benefits received by the Company on the one hand and each Agent on the
other in connection with the offering of such Securities shall be deemed to be
in the same respective proportion as the net proceeds from the offering of such
Securities (before deducting expenses) received by the Company and the total
discounts and commissions received by each Agent in respect thereof bear to the
aggregate offering price of such Securities.  The relative fault of the Company
on the one hand and of each Agent on the other shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or by such Agent
on the other and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

          The Company and each Agent agrees that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by
per capita allocation (even if all Agents were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to above in this subsection (d).  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to above in this Section 7 shall be deemed to
include, subject to the limitations set forth above, any reasonable legal or
other expenses incurred by such Indemnified Person in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 7, in no event shall an Agent be required to
contribute any amount in excess of the amount by which the total price at which
the Securities referred to in Section 7(d) that were sold by or through such
Agent exceeds the amount of any damages that such Agent has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution from any person who was not guilty of such
<PAGE>   26
                                                                              26


fraudulent misrepresentation.  The obligation of each Agent to contribute
pursuant to this subsection (d) is several (in the proportion that the
principal amount of the Securities the sale of which by or through such Agent
gave rise to such losses, claims, damages or liabilities bears to the aggregate
principal amount of the Securities the sale of which by or through any Agent
gave rise to such losses, claims, damages or liabilities) and is not joint.

     (e)  The indemnity and contribution agreements contained in this Section 7
are in addition to any liability which the Indemnifying Persons may otherwise
have to the Indemnified Persons referred to above.

     (f)  No Indemnifying Person shall, in connection with the settlement of
any pending or threatened proceeding in respect of which any Indemnified Person
is or could have been a party and indemnity could have been sought hereunder by
such Indemnified Person, assert any claim that the indemnification provided for
in this Section 7 is invalid or unenforceable.

          8.  Termination.  (a)  This Agreement may be terminated at any time
(i) by the Company with respect to any or all of the Agents or (ii) by any
Agent with respect to itself only, in each case upon the giving of written
notice of such termination to each other party hereto.  Any Terms Agreement
shall be subject to termination in the absolute discretion of the Agent or
Agents that are parties thereto on the terms set forth or incorporated by
reference therein.  The termination of this Agreement shall not require
termination of any agreement by an Agent to purchase Securities as principal
(whether pursuant to a Terms Agreement or otherwise) and the termination of
such an agreement shall not require termination of this Agreement.  In the
event this Agreement is terminated with respect to any Agent, (x) this
Agreement shall remain in full force and effect with respect to any Agent as to
which such termination has not occurred, (y) this Agreement shall remain in
full force and effect with respect to the rights and obligations of any party
which have previously accrued or which relate to Securities which are already
issued, agreed to be issued or the subject of a pending offer at the time of
such termination and (z) in any event, the provisions of the fourth paragraph
of Section 2(a), Section 2(c), the last sentence of Section 4(d) and Sections
4(f), 4(g), 5, 7, 9, 10, 12 and 15 shall survive; provided that if at the time
of termination an offer to purchase Securities
<PAGE>   27
                                                                              27


has been accepted by the Company but the time of delivery to the purchaser or
its agent of such Securities has not yet occurred, the provisions of Sections
2(b), 2(d), 4(a) through 4(e), 4(h) through 4(j) and 6 shall also survive.  If
any Terms Agreement is terminated, the provisions of the last sentence of
Section 4(d) and Sections 2(b), 2(d), 4(a), 4(b), 4(e), 4(g) through 4(j), 5,
6, 7, 9, 10, 12 and 15 (which shall have been incorporated by reference in such
Terms Agreement) shall survive.

     (b)  If this Agreement or any Terms Agreement shall be terminated by an
Agent or Agents because of any failure or refusal on the part of the Company to
comply with the terms or to fulfill any of the conditions of this Agreement or
any Terms Agreement or if for any reason the Company shall be unable to perform
its obligations under this Agreement or any Terms Agreement or any condition of
any Agent's obligations cannot be fulfilled, the Company agrees to reimburse
each Agent or such Agents as have so terminated this Agreement with respect to
themselves, severally, for all out-of-pocket expenses (including the reasonable
fees and expenses of their counsel) reasonably incurred by such Agent or Agents
in connection with this Agreement or the offering of Securities.

          9.  Position of the Agents.  Each Agent, in soliciting offers to
purchase Securities from the Company and in performing the other obligations of
such Agent hereunder (other than in respect of any purchase by an Agent as
principal, pursuant to a Terms Agreement or otherwise), is acting solely as
agent for the Company and not as principal and does not assume any obligation
towards or relationship of agency or trust with any purchaser of Securities.
Each Agent will make reasonable efforts to assist the Company in obtaining
performance by each purchaser whose offer to purchase Securities from the
Company was solicited by such Agent and has been accepted by the Company, but
such Agent shall not have any liability to the Company in the event such
purchase is not consummated for any reason.  If the Company shall default on
its obligation to deliver Securities to a purchaser whose offer it has
accepted, the Company shall (i) hold the relevant Agent harmless against any
loss, claim, damage or liability arising from or as a result of such default by
the Company and (ii) notwithstanding such default, pay to the Agent that
solicited such offer any commission to which it would be entitled in connection
with such sale.

          10.  Representations and Indemnities to Survive.  The respective
indemnities and contribution agreements, representations, warranties and other
statements of the Company, its officers and the Agents set forth in or made
pursuant to this Agreement or any agreement by an Agent to purchase Securities
as principal shall remain in full force and effect regardless of any
termination of this Agreement or any such agreement, any investigation made by
or on behalf of any Agent or any controlling person of any Agent, or the
Company, or any officer or director or any controlling person of the Company,
and shall survive each delivery of and payment for any of the Securities.

          11.  Notices.  Except as otherwise specifically provided herein or in
the Administrative Procedures, all statements, requests, notices and advices
hereunder shall be in writing, and effective only on receipt, and will be
delivered by hand, by mail (postage prepaid), by telegram (charges prepaid) or
by telex.  Communications to the Agents will be sent, in the case of [
] Attention:  Medium-Term Note Department, in the case
of -------------, to -------------- and, if sent to the Company, to it at
- ---------------------- (Telex: -------); Attention: -----------.

          12.  Successors.  This Agreement and any Terms Agreement shall be
binding upon, and inure solely to the benefit of, each Agent and the Company,
and to the extent provided in Section 7, Section 8 and Section 10 hereof, the
officers and directors of the Company and any person who controls any Agent or
the Company, and their respective personal representatives, successors and
assigns, and no other person shall acquire or have any right under or by virtue
of this Agreement or any Terms Agreement.  No purchaser of any of the
Securities through or from any Agent hereunder shall be deemed a successor or
assign by reason of such purchase.

          13.  Amendments.  This Agreement may be amended or supplemented if,
but only if, such amendment or supplement is in writing and is signed by the
Company and each Agent; provided that the Company may from time to time,
without the consent of any Agent, amend this Agreement to add as a party hereto
one or more additional firms registered under the Exchange Act, whereupon each
such firm shall become an Agent hereunder on the same terms and conditions as
the other Agents that are parties hereto.  The Agents shall sign any

                                                                              29


amendment or supplement giving effect to the addition of any such firm as an
Agent under this Agreement.

          14.  Business Day.  Time shall be of the essence in this Agreement
and any Terms Agreement.  As used herein, the term "business day" shall mean
any day which is not a Saturday or Sunday or legal holiday or a day on which
banks in New York City are required or authorized by law or executive order to
close.

          15.  Applicable Law.  This Agreement and any Terms Agreement shall be
governed by, and construed in accordance with, the laws of the State of New
York, without giving effect to the conflict of laws provisions thereof.

          16.  Counterparts.  This Agreement and any Terms Agreement may be
signed in counterparts, each of which shall be an original, and all of which
together shall constitute one and the same instrument.

          17.  Headings.  The headings of the sections of this Agreement have
been inserted for convenience of reference only and shall not be deemed a part
of this Agreement.

                          MEDIUM-TERM NOTES, SERIES A
                           ADMINISTRATIVE PROCEDURES

                        -------------------------------



                 The Medium-Term Notes, Series A (the "Notes"), are to be
offered on a continuous basis by OLIN CORPORATION (the "Company").  Each of [
] , -------------- and ------------------ (each an "Agent") has agreed to
solicit offers to purchase the Notes in registered form.  The Notes are being
sold pursuant to a Distribution Agreement dated as of --------------- --, 1993
(the "Agreement") between the Company and the Agents.  In the Agreement, each
Agent has agreed to use its best efforts to solicit purchases of the Notes.
Each Agent, as principal, may purchase Notes for its own account and, if such
Agent so elects, the Company and such Agent will enter into a Terms Agreement,
as contemplated by the Agreement.  The Company may also solicit offers to
purchase and may sell Notes directly on its own behalf to investors.

          The Notes will be issued under an Indenture dated as of June 15, 1992
(as supplemented or amended from time to time, the "Indenture") between the
Company and Chemical Bank, as trustee (the "Trustee").  The Trustee will be the
Registrar, Calculation Agent, Authenticating Agent and Paying Agent for the
Notes, and will perform the duties specified herein.  Notes will bear interest
at a fixed rate (the "Fixed Rate Notes"), which may be zero in the case of
certain original issue discount notes (the "OID Notes"), or at floating rates
(the "Floating Rate Notes").  Fixed Rate Notes may pay a level amount in
respect of both interest and principal amortized over the life of the Notes
("Amortizing Notes").  Each Note will be represented by either a Global
Security (as defined below) delivered to the Trustee, as agent for The
Depository Trust Company ("DTC"), and recorded in the book-entry system
maintained by DTC (a "Book-Entry Note") or a certificate delivered to the
holder thereof or a person designated by such holder (a "Certificated Note").
Except in limited circumstances, an owner of a Book-Entry Note will not be
entitled to receive a Certificated Note.

     Book-Entry Notes, which may be payable solely in U.S. dollars, will be
issued in accordance with the
<PAGE>   35
                                                                               2

administrative procedures set forth in Part I hereof as they may subsequently
be amended as the result of changes in DTC's operating procedures, and
Certificated Notes will be issued in accordance with the administrative
procedures set forth in Part II hereof.  Unless otherwise defined herein, terms
defined in the Indenture or the Notes shall be used herein as therein defined.

            PART I:  ADMINISTRATIVE PROCEDURES FOR BOOK-ENTRY NOTES

          In connection with the qualification of the Book-Entry Notes for
eligibility in the book-entry system maintained by DTC, the Trustee will
perform the custodial, document control and administrative functions described
below, in accordance with its respective obligations under a Letter of
Representation from the Company and the Trustee to DTC, dated as of the date
hereof (the "Letter of Representation"), and a Medium-Term Note Certificate
Agreement between the Trustee and DTC, dated as of ----------------- --, 19--,
and its obligations as a participant in DTC, including DTC's Same-Day Funds
Settlement System ("SDFS").

Issuance:           On any date of settlement (as defined under "Settlement" 
                    below) for one or more Book-Entry Notes, the Company will 
                    issue a single global security in fully registered form 
                    without coupons (a "Global Security") representing up to U.S
                    $---,000,000 principal amount of all such Notes that have
                    the same Maturity Date, redemption or repayment provisions,
                    Interest Payment Dates, Original Issue Date, original issue
                    discount provisions (if any), and, in the case of Fixed
                    Rate Notes, Interest Rate, modified payment upon
                    acceleration (if any), amortization schedule (if any) or,
                    in the case of Floating Rate Notes, Initial Interest Rate,
                    Interest Payment Dates, Interest Payment Period,
                    Calculation Agent, Base Rate, Index Maturity, Interest
                    Reset Period, Interest Reset Dates, Spread or Spread
                    Multiplier (if any), \ \ Minimum Interest Rate (if any) and
                    Maximum Interest Rate (if any) and, in each case, any other
                    relevant terms

                                                                               3

                    (collectively "Terms"). Each Global Security will be dated
                    and issued as of the date of its authentication by the
                    Trustee.  Each Global Security will bear an "Interest
                    Accrual Date," which will be (i) with respect to an
                    original Global Security (or any portion thereof), its
                    original issuance date and (ii) with respect to any Global
                    Security (or any portion thereof) issued subsequently upon
                    exchange of a Global Security, or in lieu of a destroyed,
                    lost or stolen Global Security, the most recent Interest
                    Payment Date to which interest has been paid or duly
                    provided for on the predecessor Global Security or
                    Securities (or if no such payment or provision has been
                    made, the original issuance date of the predecessor Global
                    Security), regardless of the date of authentication of such
                    subsequently issued Global Security.  Book-Entry Notes may
                    only be denominated and payable in U.S. dollars.  No Global
                    Security will represent (i) both Fixed Rate and Floating
                    Rate Book-Entry Notes or (ii) any Certificated Note. \ \


Identification      The Company has arranged with the CUSIP Service Bureau of 
Numbers:            Standard & Poor's Corporation (the "CUSIP Service Bureau") 
                    for the reservation of a series of approximately 900 CUSIP 
                    numbers (including tranche numbers) for assignment to the 
                    Global Securities representing the Book-Entry Notes.  The 
                    Company has obtained from the CUSIP Service Bureau a
                    written  list of such series of reserved CUSIP numbers and
                    has  delivered to the Trustee and DTC the written list of
                    900  CUSIP numbers of such series.  The \ \ Trustee will
                    assign  CUSIP numbers to Global Securities as described
                    below under Settlement Procedure "B".  DTC will notify the
                    CUSIP Service Bureau periodically of the CUSIP numbers that
<PAGE>   37
                                                                               4

                    the \ \ Trustee has assigned to Global Securities.  At any 
                    time when fewer than 100 of the reserved CUSIP numbers 
                    remain unassigned to Global Securities, the Trustee shall so
                    advise the Company and, if it deems necessary, the Company
                    will reserve additional CUSIP numbers for assignment to
                    Global Securities representing Book-Entry Notes.  Upon
                    obtaining such additional CUSIP numbers, the Company shall
                    deliver a list of such additional CUSIP number to the
                    Trustee and DTC.

Registration:       Each Global Security  will be registered in the name of
                    Cede  & Co., as nominee for DTC, on the security register
                    maintained under the Indenture.  The beneficial owner of a
                    Book-Entry Note (or one or more indirect participants in
                    DTC designated by such owner) will designate one or more
                    participants in DTC with respect to such Note (the
                    "Participants") to act as agent or agents for such owner in
                    connection with the book-entry system maintained by DTC and
                    DTC will record in book-entry form, in accordance with
                    instructions provided by such Participants, a credit
                    balance with respect to such beneficial owner in such Note
                    in the account of such Participants.  The ownership
                    interest of such beneficial owner in such Note will be
                    recorded through the records of such Participants or
                    through the separate records of such Participants and one
                    or more indirect participants in DTC.

Transfers:          Transfers of a Book-Entry Note will be accompanied by book
                    entries made by DTC and, in turn, by Participants (and in
                    certain cases, one or more indirect participants in DTC)
                    acting on behalf of beneficial transferors and transferees
                    of such Note.

Exchanges:          The Trustee may deliver to DTC and the CUSIP Service Bureau
                    at any time a

                                                                               5

                    written notice of consolidation specifying (i) the CUSIP
                    numbers of two or more Outstanding Global Securities that
                    represent Book-Entry Notes having the same Terms and for
                    which interest has been paid to the same date, (ii) a date,
                    occurring at least thirty days after such written notice is
                    delivered and at least thirty days before the next Interest
                    Payment Date for such Book-Entry Notes, on which such
                    Global Securities shall be exchanged for a single
                    replacement Global Security and (iii) a new CUSIP number to
                    be assigned to such replacement Global Security.  Upon
                    receipt of such a notice, DTC will send to its Participants
                    (including the Trustee) a written reorganization notice to
                    the effect that such exchange will occur on such date.
                    Prior to the specified exchange date, the Trustee will
                    deliver to the CUSIP Service Bureau a written notice
                    setting forth such exchange date and the new CUSIP number
                    and stating that, as of such exchange date, the CUSIP
                    numbers of the Global Securities to be exchanged will no
                    longer be valid.  On the specified exchange date, the
                    Trustee will exchange such Global Securities for a single
                    Global Security bearing the new CUSIP number and a new
                    Interest Accrual Date, and the CUSIP numbers of the
                    exchanged Global Securities will, in accordance with CUSIP

                    principal amount, one Global Security will be authenticated

                    of the exchanged Global Security and an additional Global
                    Security will be authenticated and issued to represent any

                    Securities (see "Denominations" below).

Maturities:         Each Book-Entry Note will mature on a date from nine months
                    to \ \ 30 \ \ years from its date of issue.

Notice of           The Trustee will give notice to DTC
Redemption and      prior to each Redemption Date or
Repayment Dates:    Repayment Date (as specified in the Note), if any, at the
                    time and in the manner set forth in the Letter of 
                    Representation.

Denominations:      Book-Entry Notes will be issued in principal amounts of
                    \ \ $100,000 or an integral multiple of $1,000 in excess 
                    thereof. Global Securities will be denominated in principal 
                    amounts not in excess of $---,000,000.  If one or more 
                    Book-Entry Notes having an aggregate principal amount in 
                    excess of $---,000,000 would, but for the preceding 
                    sentence, be represented by a single Global Security, then 
                    one Global Security will be issued to represent each 
                    $---,000,000 principal amount of such Book-Entry Note or 
                    Notes and an additional Global Security will be issued
                    to  represent any remaining principal amount of such
                    Book-Entry Note  or Notes.  In such a case, each of the
                    Global Securities representing such Book-Entry Note or Notes
                    shall be assigned the same CUSIP number.

Interest:           General.  Interest on each Book-Entry Note will accrue from 
                    the Interest Accrual Date of the Global Security
                    representing such Note.  Unless otherwise specified therein,
                    each payment of interest on a Book-Entry Note will include
                    interest accrued to but excluding the Interest Payment Date;
                    provided that in the case of Floating Rate Notes with
                    respect to which the Interest Reset Period is daily or
                    weekly, interest payable on any Interest Payment Date

                    except that at maturity or earlier redemption or repayment,
                    the interest payable will include interest accrued to, but
                    excluding, the Maturity Date or the date of redemption or
                    repayment, as the case may be.  Interest payable at the
                    maturity \ \ or upon redemption or repayment \ \ of a Book-

                    principal of such Note is payable.  Standard & Poor's 
                    Corporation will use the information received in the

                    the case of a Fixed Rate Book-Entry Note issued between a 
                    Record Date and an Interest Payment Date or on an Interest

                    the Interest Payment Date following the next succeeding 
                    Record Date.  If any Interest Payment Date for a Fixed 
                    Rate Book-Entry Note is not a Business Day, the payment 
                    due on such day shall be made on the next succeeding 
                    Business Day and no interest shall accrue on such payment 
                    for the period from and after such Interest Payment Date.

                    made on Floating Rate Book-Entry Notes monthly, quarterly,
                    semiannually or annually.  Unless otherwise specified
                    pursuant to Settlement Procedure "A" below, interest will
                    be payable, in the case of Floating Rate Book-Entry Notes
                    with a daily, weekly or monthly Interest Reset Date, on the
                    third Wednesday of each month or on the third Wednesday of
                    --------, --------, --------- - and ---------, as specified

                    a LIBOR Note if such Business Day is in the next succeeding
                    calendar month, such Interest Payment Date will be the
                    immediately preceding Business Day; and provided, further,
                    that in the case of a Floating Rate Book-Entry Note issued
                    between a Record Date and the related Interest Payment Date

                    succeeding Record Date, [and in such case, notwithstanding
                    the fact that an Interest Reset Date may occur prior to
                    such Interest Payment Date, the Initial Interest Rate shall
                    remain in effect until the first Interest Reset Date
                    occurring on or subsequent to such Interest Payment Date.]

                    Notice of Interest Payment and Record Dates.  On the first

                    of each year, the Trustee will deliver to the Company and
                    DTC a written list of Record Dates and Interest Payment
                    Dates that will occur with respect to Book-Entry Notes
                    during the six-month period beginning on such first
                    Business Day.  Promptly after each date upon which interest
                    is determined for Floating Rate Notes issued in book-entry
                    form, the Calculation Agent will notify the Company, the
                    Trustee and Standard & Poor's Corporation of the interest
                    rates determined on such dates.

                    Floating Rate Book-Entry Notes.  Interest rates on Floating
                    Rate Book-Entry Notes will be determined as set forth in
                    the form of such Notes.  Interest on Floating Rate
                    Book-Entry Notes will be calculated on the basis of actual
                    days elapsed and a year of 360 days, except that, in the
                    case of Treasury Rate Notes, interest will be calculated on
                    the basis of the actual number of days in the year.

Payments of         Payments of Interest Only.  Promptly after each Record  
Principal and       Date, the Trustee will deliver to the Company and DTC a 
Interest:           written notice specifying by CUSIP number the amount of 
                    interest to be paid on each Global Security [other than an 
                    Amortizing Note] on the following Interest Payment Date 
                    (other than an Interest Payment Date coinciding with 
                    maturity or any earlier redemption or repayment date) and 
                    the total of such amounts.  DTC will confirm the amount 
                    payable on each such Global Security on such Interest 
                    Payment Date by reference to the daily bond reports 
                    published by Standard & Poor's Corporation.  [In the case 
                    of Amortizing Notes, the Trustee will provide separate 
                    written notice to the Company and to DTC prior to each 
                    Interest Payment Date at the time and in the manner set 
                    forth in the Letter of Representation.]  The Company will 
                    pay to the Trustee, as paying agent, the total amount of 
                    interest due on such Interest Payment Date [(and,
                    in the case of an Amortizing Note, principal and interest)]
                    (other than at maturity), and the Trustee will pay such

                    Business Day of each month, the Trustee will deliver to the
                    Company and DTC a written list of principal and interest to
                    be paid on each Global Security [other than an Amortizing
                    Note] maturing either at maturity or on a redemption or
                    repayment date in the following month.  The Company and DTC
                    will confirm the amounts of such principal and interest
                    payments with respect to each such Global Security on or
                    about the fifth Business Day preceding the Maturity Date or

                    the case of Amortizing Notes, the Trustee will provide
                    separate written notice to the Company and to DTC prior to
                    the Maturity Date and any redemption or repayment date, as
                    the case may be, at the times and in the manner set forth
                    in the Letter of Representation.]  The Company will pay to
                    the Trustee, as the paying agent, the principal amount of
                    such Global Security, together with interest due at such
                    Maturity Date or redemption or repayment date.  The Trustee
                    will pay such amounts to DTC at the times and in the manner
                    set forth below under "Manner of Payment."

                    Payments Not on Business Days.  If any Interest Payment
                    Date or the Maturity Date or redemption or repayment date
                    of a Global Security representing Fixed Rate Book-Entry
                    Notes is not a Business Day, the payment due on such day
                    shall be made on the next succeeding Business Day and no

                    and after such Interest Payment Date, Maturity Date or
                    redemption or repayment date, as the case may be.  If any

                    repayment date of a Global Security representing a Floating
                    Rate Book-Entry Note would otherwise fall on a day that is
                    not a Business Day, the payment due on such day shall be

                    the next succeeding day that is a Business Day with respect
                    to such Notes with the same effect as if such Business Day
                    were the Interest Payment Date, Maturity Date or date of
                    redemption or repayment, as the case may be, except that,
                    in the case of Book-Entry LIBOR Notes, if such Business Day
                    is in the next succeeding calendar month, such Interest
                    Payment Date or redemption or repayment date shall be the
                    immediately preceding day that is a Business Day with

                    payment to DTC of the principal and interest due on the
                    Maturity Date or redemption or repayment date of such
                    Global Security, the Trustee will cancel such Global
                    Security in accordance with the terms of the Indenture and
                    deliver it to the Company with a certificate of
                    cancellation.  [Upon request/ On the first Business Day of
                    each month], the Trustee will deliver to the Company a
                    written statement indicating the total principal amount of
                    outstanding Book-Entry Notes as of the immediately
                    preceding Business Day.

                    Manner of Payment.  The total amount of any principal and
                    interest due on Global Securities on any Interest Payment
                    Date or at maturity or upon redemption or repayment shall
                    be paid by the Company to the Trustee in funds available
                    for immediate use by the Trustee as of 9:30 a.m. (New York
                    City time) on such date.  The Company will make such
                    payment on such Global Securities by wire transfer to the
                    Trustee or by instructing the Trustee to withdraw funds
                    from an account maintained by the Company at the Trustee.

Settle:             SDFS deliver order with respect to a Book-Entry Note
                    pursuant to Settlement Procedure "F", the Trustee may 
                    deliver to DTC, through DTC's Participant Terminal System, 
                    as soon as practicable a withdrawal message instructing DTC 
                    to debit such Note to the Trustee's participant account, 
                    provided that the Trustee's participant account contains a 
                    principal amount of the Global Security representing such 
                    Note that is at least equal to the principal amount to be 
                    debited. If a withdrawal message is processed with respect 
                    to all the Book-Entry Notes represented by a Global 
                    Security, the Trustee will mark such Global Security 
                    "cancelled," make appropriate entries in the Trustee's 
                    records and send such cancelled Global Security to the 
                    Company.  The CUSIP number assigned to such Global Security
                    shall, in accordance with CUSIP Service Bureau procedures, 
                    be cancelled and not immediately reassigned.  If a 
                    withdrawal message is processed with respect to one or 
                    more, but not all, of the Book-Entry Notes represented
                    by a Global Security, the Trustee will exchange such Global
                    Security for two Global Securities, one of which shall
                    represent such Book-Entry Note or Notes and shall be
                    cancelled immediately after issuance and the other of which
                    shall represent the remaining Book-Entry Notes previously
                    represented by the surrendered Global Security and shall
                    bear the CUSIP number of the surrendered Global Security.

                    If the purchase price for any Book-Entry Note is not timely
                    paid to the Participants with respect to such Note by the
                    beneficial purchaser thereof (or a person, including an
                    indirect participant in DTC, acting on behalf of such
                    purchaser), such Participants and, in turn, the relevant

                    the orders entered pursuant to Settlement Procedures "F"
                    and "G", respectively.  Thereafter, the Trustee will
                    deliver the withdrawal message and take the related actions
                    described in the preceding paragraph.

                    Notwithstanding the foregoing, upon any failure to settle
                    with respect to a Book-Entry Note, DTC may take any action
                    in accordance with its SDFS operating procedures then in
                    effect.

                    In the event of a failure to settle with respect to one or
                    more, but not all, of the Book-Entry Notes to have been
                    represented by a Global Security, the Trustee will provide,
                    in accordance with Settlement Procedures "D" and "F", for
                    the authentication and issuance of a Global Security
                    representing the Book-Entry Notes to be represented by such
                    Global Security and will make appropriate entries in its
                    records.

Posting Rates       The Company and the Agents will
by Company:         discuss from time to time the rates of interest per annum
                    to be borne by and the maturity of Securities that may be 
                    sold as a result of the solicitation of offers by an Agent.
                    The Company may establish a fixed set of interest rates and
                    maturities for an offering period ("posting\ \").  If the
                    Company decides to change already posted rates, it will
                    promptly advise the Agents to suspend solicitation of
                    offers until the new posted rates have been established
                    with the Agent.

                    purpose.

                    lieu of a destroyed, lost or stolen Certificated Note, the
                    original issuance date of the predecessor Certificated

                    Note and the currency of payment of interest and principal 
                    with respect to any such Certificated Note shall be as set 
                    forth therein and in the applicable pricing supplement.

                    currency or any amount in excess thereof that is an integral
                    multiple of $1,000 (or in the case of Notes not denominated
                    in U.S. dollars, 1,000 units of such foreign currency or
                    composite currency).

Interest:           General.  Interest on each Certificated Note will accrue
                    from the Original Issue Date of such Note for the first 
                    interest period and from the most recent date to which 
                    interest has been paid for all subsequent interest periods.
                    Unless otherwise specified therein, each payment of 
                    interest on a Certificated Note will include interest

                    the interest payable will include interest accrued to, but
                    excluding, the Maturity Date or the date of redemption or
                    repayment, as the case may be.

                    Record Dates.  The Record Date with respect to any Interest
                    Payment Date in respect of a Certificated Note shall be the
                    date fifteen calendar days immediately preceding such
                    Interest Payment Date.

                    that is not a Business Day with respect to such Floating
                    Rate Certificated Notes, such Interest Payment Date will be
                    the next succeeding Business Day with respect to such
                    Floating Rate Certificated Notes, except in the case of a

                    Notice of Interest Payment and Record Dates.  On the first
                    Business Day of ------------, -----------, ----------- and
                    ----- ---- of each year, the Trustee will deliver to the

                    Dates that will occur with respect to Certificated Notes
                    during the six-month period beginning on such first
                    Business Day.  Promptly after each date upon which interest
                    is determined for Floating Rate Notes issued in
                    certificated form, the Calculation Agent will notify the
                    Company and the Trustee of the interest rates determined on
                    such dates.

Calculation of      Fixed Rate Certificated Notes. Interest on Fixed Rate
Interest:           Certificated Notes (including interest for partial periods) 
                    will be calculated on the basis of a year of twelve thirty-
                    day months.

                    Floating Rate Certificated Notes.  Interest rates on
                    Floating Rate Certificated Notes will be determined as set
                    forth in the form of such Notes.  Interest on Floating Rate
                    Certificated Notes will be calculated on the basis of
                    actual days elapsed and a year of 360 days, except that, in
                    the case of Treasury Rate Notes, interest will be
                    calculated on the basis of the actual number of days in the
                    year.

Payments of         The Company will pay to the Trustee, as the paying agent,
Principal and       the principal amount of each Certificated Note [(other than

                    Date or upon redemption or repayment of such Note in funds
                    available for immediate use by the Trustee.]  The Trustee
                    will pay such amount to the holder of such Note at its

                    located outside the United States and, with respect to

                    provide the Trustee with appropriate and timely wire

                    Promptly after each Record Date, the Trustee will deliver
                    to the Company a written notice specifying the amount of

                    an Amortizing Note] on the following Interest Payment Date
                    (other than an Interest Payment Date coinciding with
                    maturity or any earlier redemption or repayment date) and
                    the total of such amounts.  [In the case of Amortizing

                    to be paid on each Amortizing Note on the following
                    Interest Payment Date (other than an Interest Payment Date
                    coinciding with maturity or any earlier redemption or
                    repayment date) and the total of such amounts.]  Interest

                    Trustee will deliver to the Company a written list of
                    principal and interest, to the extent ascertainable, to be
                    paid on each Certificated Note [including Amortizing Notes]
                    maturing or to be redeemed or repaid in the following
                    month.  The Trustee will be responsible for withholding
                    taxes on interest paid on Certificated Notes as required by
                    applicable law.

                    date, as the case may be.  If any Interest Payment Date or
                    the Maturity Date or redemption or repayment date of a
                    Floating Rate Certificated Note would otherwise fall on a
                    day that is not a Business Day with respect to such Note,
                    the payment due on such day shall be made on the next
                    succeeding day that is a Business Day with respect to such
                    Note with the same effect as if such Business Day were the
                    stated Interest Payment Date, Maturity Date or date of
                    redemption or repayment, as the case may be, except that,
                    in the case of Certificated LIBOR Notes, if such Business
                    Day is in the next succeeding calendar month, such Interest
                    Payment Date, Maturity Date or redemption or repayment date
                    shall be the immediately preceding day that is a Business
                    Day with respect to such Certificated LIBOR Notes.

                    paragraph of Rule 424(b) under the Act and will deliver the

                    cause such Pricing Supplement to be delivered to the 
                    purchaser of the Note.

although at the date of such Debt Security or of the execution of this
Indenture any such person was not such officer.

     SECTION 2.05.  Authentication and Delivery of Debt Securities.  At any
time and from time to time after the execution and delivery of this Indenture,
the Company may deliver Debt Securities of any series executed by the Company
to the Trustee for authentication, and the Trustee shall thereupon authenticate
and deliver said Debt Securities to or upon the written order of the Company,
signed by its Chairman of the Board or its President or a Vice President and by
its Treasurer or its Controller or its Secretary or an Assistant Treasurer or
an Assistant Controller or an Assistant Secretary.  In authenticating such Debt
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Debt Securities, the Trustee shall be entitled to receive,
and (subject to Section 7.01) shall be fully protected in relying upon:

          (1) a copy of any resolution or resolutions of the Board of Directors
     of the Company, certified by the Secretary or Assistant Secretary of the
     Company,
<PAGE>   22
                                                                              12

     authorizing the terms of issuance of any series of Debt Securities;

          (2) an executed supplemental indenture, if any;

          (3) an Officers' Certificate;

          (4) an Opinion of Counsel prepared in accordance with Section 15.05
     which shall also state:

               (a) that the form of such Debt Securities has been established
          by or pursuant to a resolution of the Board of Directors of the
          Company or by a supplemental indenture as permitted by Section 2.01
          in conformity with the provisions of this Indenture;

               (b) that the terms of such Debt Securities have been established
          by or pursuant to a resolution of the Board of Directors of the
          Company or by a supplemental indenture as permitted by Section 2.03
          in conformity with the provisions of this Indenture;

               (c) that such Debt Securities, when authenticated and delivered
          by the Trustee and issued by the Company in the manner and subject to
          any conditions specified in such Opinion of Counsel, will constitute
          valid and binding obligations of the Company, enforceable in
          accordance with their terms except as (i) the enforceability thereof
          may be limited by bankruptcy, insolvency or similar laws affecting
          the enforcement of creditors' rights generally and (ii) rights of
          acceleration and the availability of equitable remedies may be
          limited by equitable principles of general applicability;

               (d) that the Company has the corporate power to issue such Debt
          Securities, and has duly taken all necessary corporate action with
          respect to such issuance;

               (e) that the issuance of such Debt Securities will not
          contravene the charter or by-laws of the Company or result in any
          violation of any of the terms or provisions of any law or regulation
          or of
<PAGE>   23
                                                                              13

          any indenture, mortgage or other agreement known to such counsel 
          by which the Company is bound; and

               (f) that all laws and requirements in respect of the execution
          and delivery by the Company of the Debt Securities have been complied
          with and that authentication and delivery of such Debt Securities and
          the execution and delivery of any supplemental indenture (if any)
          will not violate the terms of this Indenture; and

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

     The Trustee shall have the right to decline to authenticate and deliver
any Debt Securities under this Section if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the
Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or vice presidents
shall determine that such action would expose the Trustee to personal liability
to existing Holders.

     Unless otherwise provided in the form of Debt Security for any series, each
Debt Security shall be dated the date of its authentication.

     SECTION 2.06.  Denomination of Debt Securities.  Unless otherwise provided
in the form of Debt Security for any series, the Debt Securities of each series
shall be issuable in registered form without coupons in such denominations as
shall be specified or contemplated by Section 2.03.  In the absence of any such
specification with respect to the Debt Securities of any series, the Debt
Securities of such series shall be issuable in denominations of $1,000 and any
integral multiple thereof.

     SECTION 2.07.  Registration of Transfer and Exchange.  The Company shall
keep a register for each series of Debt Securities issued hereunder
(hereinafter collectively referred to as the "Debt Security Register"), in
which, subject to such reasonable regulations as it may prescribe, the Company
shall register Debt Securities and shall register the transfer of Debt
Securities as in this Article Two provided.  At all reasonable times such
register shall be open for inspection by the Trustee.  Subject to Section 2.15,
upon due presentment for registration of transfer of any Debt Security at any
<PAGE>   24
                                                                              14

office or agency to be maintained by the Company in accordance with the
provisions of Section 4.02, the Company shall execute and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
Debt Security or Debt Securities of authorized denominations for a like
aggregate principal amount.

     Unless and until otherwise determined by the Company by resolution of its
Board of Directors, the register of the Company for the purpose of
registration, exchange or registration of transfer of the Debt Securities shall
be kept at the corporate trust office of the Trustee and, for this purpose, the
Trustee shall be designated "Registrar".

     Debt Securities of any series may be exchanged for a like aggregate
principal amount of Debt Securities of the same series of other authorized
denominations.  Subject to Section 2.15, Debt Securities to be exchanged shall
be surrendered at the office or agency to be maintained by the Company as
provided in Section 4.02, and the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor the Debt Security or Debt
Securities which the Holder making the exchange shall be entitled to receive.

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

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

     No service charge shall be made for any exchange or registration of
transfer of Debt Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto.

     The Company shall not be required (a) to issue, register the transfer of
or exchange any Debt Securities for a period of 15 days next preceding any
mailing of notice of redemption of Debt Securities of such series, or (b) to
<PAGE>   25
                                                                              15

register the transfer of or exchange any Debt Securities selected, called or
being called for redemption.

     None of the Company, the Trustee, any agent of the Trustee, any paying 
agent or any Registrar will have any responsibility or liability for any aspect
of the records relating to, or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     SECTION 2.08.  Temporary Debt Securities.  Pending the preparation of
definitive Debt Securities the Company may execute and the Trustee shall
authenticate and deliver temporary Debt Securities (printed, lithographed or
typewritten) of any authorized denomination, and substantially in the form of
the definitive Debt Securities but with such omissions, insertions and
variations as may be appropriate for temporary Debt Securities, all as may be
determined by the Company with the concurrence of the Trustee.  Temporary Debt
Securities may contain such reference to any provisions of this Indenture as
may be appropriate.  Every temporary Debt Security shall be executed by the
Company and be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with like effect, as the definitive Debt
Securities.  The Company shall execute and furnish definitive Debt Securities
as soon as practicable and thereupon any or all temporary Debt Securities may
be surrendered in exchange therefor at the corporate trust office of the
Trustee, and the Trustee shall authenticate and deliver in exchange for such
temporary Debt Securities a like aggregate principal amount of definitive Debt
Securities.  Until so exchanged, the temporary Debt Securities shall be
entitled to the same benefits under this Indenture as definitive Debt
Securities authenticated and delivered hereunder.

     SECTION 2.09.  Mutilated, Destroyed, Lost or Stolen Debt Securities.  In
case any temporary or definitive Debt Security shall become mutilated or be
destroyed, lost or stolen, in the absence of written notice to the Company or
the Trustee that such Debt Security has been acquired by a bona fide purchaser,
the Company in its discretion may execute, and upon its request the Trustee
shall authenticate and deliver, a new Debt Security bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated
Debt Security, or in lieu of and substitution for the Debt Security so
destroyed, lost or stolen.  In every case the applicant for a substituted Debt
Security shall furnish to the Company and to the Trustee such security or
indemnity as may be required by them to save each of them harmless from all
risk, however remote, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company and to the Trustee evidence to
their satisfaction of the destruction,
<PAGE>   26
                                                                              16

loss or theft of such Debt Security and of the ownership thereof.  The Trustee
may authenticate any such substituted Debt Security and deliver the same upon
the written request or authorization of any officer of the Company.  Upon the
issuance of any substituted Debt Security, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses connected therewith.  In
case any Debt Security which has matured or is about to mature or which has
been called for redemption shall become mutilated or be destroyed, lost or
stolen, the Company may, instead of issuing a substituted Debt Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Debt Security) if the applicant for such payment shall furnish
the Company and the Trustee with such security or indemnity as either may
require to save it harmless from all risk, however remote, and, in case of
destruction, loss or theft, evidence to the satisfaction of the Company and the
Trustee of the destruction, loss or theft of such Debt Security and of the
ownership thereof.

     Every substituted Debt Security issued pursuant to the provisions of this
Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Debt Security shall be found at
any time, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Debt Securities duly issued
hereunder.  All Debt Securities shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Debt Securities,
and shall preclude any and all other rights or remedies, notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities
without their surrender.

     SECTION 2.10.  Cancellation of Surrendered Debt Securities.  All Debt
Securities surrendered for payment, redemption, registration of transfer or
exchange shall, if surrendered to the Company or any paying agent or a
Registrar, be delivered to the Trustee for cancellation by it, or if
surrendered to the Trustee, shall be cancelled by it, and no Debt Securities
shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture.  All cancelled Debt Securities held by the
<PAGE>   27
                                                                              17

Trustee shall be destroyed and certification of their destruction delivered to
the Company, unless otherwise directed.  On request of the Company, the Trustee
shall deliver to the Company cancelled Debt Securities held by the Trustee.  If
the Company shall acquire any of the Debt Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Debt Securities unless and until the same are delivered or
surrendered to the Trustee for cancellation.

     SECTION 2.11.  Provisions of the Indenture and Debt Securities for the
Sole Benefit of the Parties and the Holders.  Nothing in this Indenture or in
the Debt Securities, expressed or implied, shall give or be construed to give
to any person, firm or corporation, other than the parties hereto and the
holders of the Debt Securities, any legal or equitable right, remedy or claim
under or in respect of this Indenture, or under any covenant, condition or
provision herein contained; all its covenants, conditions and provisions being
for the sole benefit of the parties hereto and of the Holders of the Debt
Securities.

     SECTION 2.12.  Interest Rights Preserved.  Each Debt Security delivered
under this Indenture upon transfer of or in exchange for or in lieu of any Debt
Security of such series shall carry all the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Debt Security of such
series, and each such Debt Security of such series shall be so dated, that
neither gain nor loss in interest shall result from such transfer, exchange or
substitution.

     SECTION 2.13.  Securities Denominated in Foreign Currencies.  For the
purposes of calculating the principal amount of Securities of any series
denominated in a foreign currency or in units of two or more foreign currencies
(including European Currency Units) for any purpose under this Indenture, the
principal amount of such Debt Securities at any time outstanding shall be
deemed to be that amount of United States dollars that could be obtained for
such principal amount on the basis of a spot rate of exchange specified to the
Trustee for such series in an Officers' Certificate for such currency or
currency units into United States dollars as of the date of any such
calculation.

     In the event any foreign currency or currencies or units of two or more
currencies in which any payment with respect to any series of Debt Securities
may be made ceases
<PAGE>   28
                                                                              18

to be a freely convertible currency on United States currency markets, for any
date thereafter on which payment of principal of, premium, if any, or interest,
if any, on the Debt Securities of a series is due, the Company shall select the
currency of payment for use on such date, all as provided in the Debt
Securities of such series.  In such event, the Company shall, as provided in
the Debt Securities of such series, notify the Trustee of the currency which it
has selected to constitute the funds necessary to meet the Company's
obligations on such payment date and of the amount of such currency to be paid.
Such amount shall be determined as provided in the Debt Securities of such
series.  The payment to the Trustee with respect to such payment date shall be
made by the Company solely in the currency so selected.

     SECTION 2.14.  Wire Transfers.  Notwithstanding any other provision to the
contrary in this Indenture, the Company may make any payment of monies required
to be deposited with the Trustee on account of principal, premium or interest
on the Debt Securities (whether pursuant to optional or mandatory redemption
payments, interest payments or otherwise) by wire transfer in immediately
available funds to an account designated by the Trustee on or before the date
such monies are to be paid to the holders of the Debt Securities in accordance
with the terms hereof.

     SECTION 2.15.  Securities Issuable in the Form of a Global Security.  
(a) If the Company shall establish pursuant to Sections 2.01 and 2.03 that the
Debt Securities of a particular series are to be issued in whole or in part in
the form of one or more Global Securities, then the Company shall execute and
the Trustee or its agent shall, in accordance with Section 2.05, authenticate
and deliver, such Global Security or Securities, which (i) shall represent, and
shall be denominated in an amount equal to the aggregate principal amount of,
the Outstanding Debt Securities of such series to be represented by such Global
Security or Securities, or such portion thereof as the Company shall specify in
an Officer's Certificate, (ii) shall be registered in the name of the
Depositary for such Global Security or Securities or its nominee, (iii) shall
be delivered by the Trustee or its agent to the Depositary or pursuant to the
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect:  'Unless and until it is exchanged in whole or in part for
the individual Debt Securities represented hereby, this Global Security may not
be transferred except as a whole by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary' or such other 
legend as may then be required by the Depositary for such Global Security or 
Securities.

                 (b)      Notwithstanding any other provision of this Section
         2.15 or of Section 2.07 to the contrary, and subject to the provisions
         of paragraph (c) below, unless the terms of a Global Security
         expressly permit such Global Security to be exchanged in whole or in
         part for definitive Debt Securities in registered form, a Global
         Security may be transferred, in whole but not in part and in the
         manner provided in Section 2.07, only by the Depositary to a nominee
         of the Depositary for such Global Security, or by a nominee of the
         Depositary to the Depositary or another nominee of the Depositary, or
         by the Depositary or a nominee of the Depositary to a successor
         Depositary for such Global Security selected or approved by the
         Company, or to a nominee of such successor Depositary.

                 (c)      (i)     If at any time the Depositary for a Global
         Security or Securities notifies the Company that it is unwilling or
         unable to continue as Depositary for such Global Security or
         Securities or if at any time the Depositary for the Debt Securities
         for such series shall no longer be eligible or in good standing under
         the Securities Exchange Act of 1934, as amended, or other applicable
         statute or regulation, the Company shall appoint a successor
         Depositary with respect to such Global Security or Securities.  If a
         successor Depositary for such Global Security or Securities is not
         appointed by the Company within 90 days after the Company receives
         such notice or becomes aware of such ineligibility, the Company will
         execute, and the Trustee or its agent, upon receipt of a written order
         of the Company signed by its Chairman of the Board or its President or
         a Vice President and by its Treasurer or its Controller or its
         Secretary or an Assistant Treasurer or an Assistant Controller or an
         Assistant Secretary for the authentication and delivery of individual
         Debt Securities of such series in exchange for such Global Security,
         will authenticate and deliver, individual Debt Securities of such
         series of like tenor and terms in definitive form in an aggregate
         principal amount equal to the principal amount of the Global Security
         in exchange for such Global Security or Securities.

                 (ii)     The Company may at any time and in its sole
         discretion determine that the Debt Securities of any series or portion
         thereof issued or issuable in the form of one or more Global
         Securities shall no longer be represented by such Global Security or
         Securities. In such event the Company will execute, and the Trustee, 
         upon receipt of a written order of the Company, signed by its 
         Chairman of the Board or any Vice Chairman or its President or a Vice 
         President and by its Treasurer or its Controller or its Secretary or 
         an Assistant Treasurer or an Assistant Controller or Assistant 
         Secretary, for the authentication and delivery of individual Debt 
         Securities of such series in exchange in whole or in part for such 
         Global Security, will authenticate and deliver individual Debt 
         Securities of such series of like tenor and terms in definitive form 
         in an aggregate principal amount equal to the principal amount of 
         such series or portion thereof in exchange for such Global Security 
         or Securities.

                 (iii) If specified by the Company pursuant to Sections 2.01
         and 2.03 with respect to Debt Securities issued or issuable in the
         form of a Global Security, the Depositary for such Global Security may
         surrender such Global Security in exchange in whole or in part for
         individual Debt Securities of such series of like tenor and terms in
         definitive form on such terms as are acceptable to the Company, the
         Trustee and such Depositary.  Thereupon the Company shall execute, and
         the Trustee or its agent upon receipt of a written order by the
         Company, signed by its Chairman of the Board or any Vice Chairman or
         its President or a Vice President and by its Treasurer or its
         Controller or its Secretary or an Assistant Treasurer or an Assistant
         Controller or Assistant Secretary, for the authentication and delivery
         of definitive Debt Securities of such series shall authenticate and
         deliver, without service charge, (1) to each person specified by such
         Depositary a new Debt Security or Securities of the same series of
         like tenor and terms and of any authorized denomination as requested
         by such person in aggregate principal amount equal to and in exchange
         for such person's beneficial interest in the Global Security; and (2)
         to such Depositary a new Global Security of like tenor and terms and
         in an authorized denomination equal to the difference, if any, between
         the principal amount of the surrendered Global Security and the
         aggregate principal amount of Debt Securities delivered to Holders
         thereof.

                 (iv)     In any exchange provided for in any of the preceding
         three paragraphs, the Company will execute and the Trustee or its
         agent will authenticate and deliver individual Debt Securities in
         definitive registered form in authorized denominations.  Upon the
         exchange of the entire principal amount of a Global Security for
         individual Debt Securities, such Global Security shall be cancelled by
         the Trustee or its agent.  Except as provided in the preceding
         paragraph, Debt Securities issued in exchange for a Global Security
         pursuant to this Section shall be registered in such names and in such
         authorized denominations as the Depositary for such Global Security,
         pursuant to instructions from its direct or indirect participants or
         otherwise, shall instruct the Trustee or the Registrar.  The Trustee
         or the Registrar shall deliver such Debt Securities to the Persons in
         whose names such Debt Securities are so registered.

         Section 2.16.  Medium-term Securities.  Notwithstanding any contrary 
provision herein, if all Debt Securities of a series are not to be originally
issued at one time, it shall not be necessary for the Company to deliver to the
Trustee an Officers' Certificate, resolutions of the Board of Directors,
supplemental indenture, Opinion of Counsel or written order or any other
document otherwise required pursuant to Sections 2.01, 2.03, 2.05 or 14.05 at
or prior to the time of authentication of each Debt Security of such series if
such documents are delivered to the Trustee or its agent at or prior to the
authentication upon original issuance of the first such Debt Security of such
series to be issued; provided that any subsequent request by the Company to the
Trustee to authenticate Debt Securities of such series upon original issuance
shall constitute a representation and warranty by the Company that as of the
date of such request, the statements made in the Officers' Certificate
delivered pursuant to Section 2.05 or 14.05 shall be true and correct as if
made on such date and that the Opinion of Counsel delivered at or prior to such
time of authentication of an original issuance of Debt Securities shall
specifically state that it shall relate to all subsequent issuances of Debt
Securities of such series that are identical to the Debt Securities issued in
the first issuance of Debt Securities of such series.

         A written order of the Company signed by its Chairman of the Board or 
its President or a Vice President and by its Treasurer or its Controller or its
Secretary or an Assistant Treasurer or an Assistant Controller or an Assistant
Secretary, delivered by the Company to the Trustee in the circumstances set
forth in the preceding paragraph may provide that Debt Securities which are the
subject thereof will be authenticated and delivered by the Trustee or its agent
on original issue from time to time upon the telephonic or written order of
persons designated in such written order (any such telephonic instructions to
be promptly confirmed in writing by such person) and that such persons are
authorized to determine, consistent with the Officers' Certificate,
supplemental indenture or resolution of the Board of Directors relating to such
written order, such terms and conditions of said Securities as are specified in
such Officers' Certificate, supplemental indenture or such resolution.



                                 ARTICLE THREE.

                         REDEMPTION OF DEBT SECURITIES.

     SECTION 3.01.  Applicability of Article.  The provisions of this Article
shall be applicable to the Debt Securities of any series which are redeemable
before their maturity except as otherwise specified as contemplated by Section
2.03 for Debt Securities of such series.  Section 3.06 shall be applicable to
the Debt Securities of every series issued hereunder.

     SECTION 3.02.  Notice of Redemption; Selection of Debt Securities.  In
case the Company shall desire to exercise the right to redeem all or, as the
case may be, any part of the Debt Securities of any series in accordance with
their terms, a resolution of the Board of Directors of the Company or a
supplemental Indenture, the Company shall fix a date for redemption and shall
mail or cause to be mailed a notice of such redemption at least 30 and not more
than 60 days
<PAGE>   29
                                                                              19

prior to the date fixed for redemption to the Holders of Debt Securities of
such series so to be redeemed as a whole or in part at their last addresses as
the same appear on the Debt Security Register.  Such mailing shall be by first
class mail.  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice.  In any case, failure to give such notice by mail or any
defect in the notice to the Holder of any Debt Security of a series designated
for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Debt Security of such series.

     Each such notice of redemption shall specify the date fixed for
redemption, the redemption price at which Debt Securities of such series are to
be redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Debt Securities, that any interest accrued
to the date fixed for redemption will be paid as specified in said notice, that
the redemption is for a sinking fund payment (if applicable), and that on and
after said date any interest thereon or on the portions thereof to be redeemed
will cease to accrue.  If less than all the Debt Securities of a series are to
be redeemed the notice of redemption shall specify the numbers of the Debt
Securities of that series to be redeemed.  In case any Debt Security of a
series is to be redeemed in part only, the notice of redemption shall state the
portion of the principal amount thereof to be redeemed and shall state that on
and after the date fixed for redemption, upon surrender of such Debt Security,
a new Debt Security or Debt Securities of that series in principal amount equal
to the unredeemed portion thereof will be issued.

     On or prior to the redemption date specified in the notice of redemption
given as provided in this Section 3.02, the Company will deposit with the
Trustee or with one or more paying agents an amount of money sufficient to
redeem on the redemption date all the Debt Securities or portions thereof so
called for redemption at the appropriate redemption price, together with any
accrued interest to the date fixed for redemption.

     If less than all the Debt Securities of like tenor and terms of a series 
are to be redeemed (other than pursuant to mandatory sinking fund redemptions) 
the Company will give the Trustee notice not less than 60 days prior to the 
redemption date as to the aggregate principal amount of Debt Securities to be 
redeemed

                                                                              20

and the Trustee shall select, in such manner as in its sole discretion it shall
deem appropriate and fair, the Debt Securities of that series or portions
thereof (in multiples of $1,000, except as otherwise set forth in the
applicable form of Debt Security) to be redeemed.  If any Debt Security called
for redemption shall not be so paid upon surrender thereof on such redemption
date, the principal and premium, if any, shall bear interest until paid from
the redemption date at the rate borne by the Debt Securities of that series.
If less than all the Debt Securities of unlike tenor and terms of a series are
to be redeemed, the particular Debt Securities to be redeemed shall be selected
by the Company.

     SECTION 3.03.  Payment of Debt Securities Called for Redemption.  If
notice of redemption has been given as provided in Section 3.02, the Debt
Securities or portions of Debt Securities of the series with respect to which
such notice has been given shall become due and payable on the date and at the
place or places stated in such notice at the applicable redemption price,
together with any interest accrued to the date fixed for redemption, and on and
after said date (unless the Company shall default in the payment of such Debt
Securities at the applicable redemption price, together with any interest
accrued to said date) any interest on the Debt Securities or portions of Debt
Securities of any series so called for redemption shall cease to accrue.  On
presentation and surrender of such Debt Securities at a place of payment in
said notice specified, the said Debt Securities or the specified portions
thereof shall be paid and redeemed by the Company at the applicable redemption
price, together with any interest accrued thereon to the date fixed for
redemption.

     Upon presentation of any Debt Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Company, a new Debt Security or Debt Securities
of such series, of authorized denominations, in aggregate principal amount
equal to and in exchange for the unredeemed portion of the Debt Security so
presented.

     SECTION 3.04.  Mandatory and Optional Sinking Funds.  The minimum amount
of any sinking fund payment provided for by the terms of Debt Securities of any
series, resolution of the Board of Directors or a supplemental indenture is
herein referred to as a "mandatory sinking fund payment", and any payment in
excess of such minimum amount provided for by the terms of Debt Securities of
any series, resolution of the Board of Directors or a supplemental indenture is
herein referred to as an "optional sinking fund payment".
<PAGE>   31
                                                                              21


     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any Debt Securities of a series in cash, the Company may at its
option (a) deliver to the Trustee Debt Securities of that series theretofore
purchased or otherwise acquired by the Company, or (b) receive credit for the
principal amount of Debt Securities of that series which have been redeemed
either at the election of the Company pursuant to the terms of such Debt
Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Debt Securities, resolution or
supplemental indenture; provided that such Debt Securities have not been
previously so credited.  Such Debt Securities shall be received and credited
for such purpose by the Trustee at the Redemption Price specified in such Debt
Securities, resolution or supplemental indenture for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

     SECTION 3.05.  Redemption of Debt Securities for Sinking Fund.  Not less
than 60 days prior to each sinking fund payment date for any series of Debt
Securities, the Company will deliver to the Trustee an Officers' Certificate of
the Company specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, any resolution or
supplemental indenture, the portion thereof, if any, which is to be satisfied
by payment of cash and the portion thereof, if any, which is to be satisfied by
delivering and crediting Debt Securities of that series pursuant to this
Section 3.05 (which Debt Securities, if not previously redeemed, will accompany
such certificate) and whether the Company intends to exercise its right to make
any permitted optional sinking fund payment with respect to such series.  Such
certificate shall also state that no Event of Default has occurred and is
continuing with respect to such series.  Such certificate shall be irrevocable
and upon its delivery the Company shall be obligated to make the cash payment
or payments therein referred to, if any, on or before the next succeeding
sinking fund payment date.  Failure of the Company to deliver such certificate
(or to deliver the Debt Securities specified in this paragraph) shall not
constitute a default, but such failure shall require that the sinking fund
payment due on the next succeeding sinking fund payment date for that series
shall be paid entirely in cash and shall be sufficient to redeem the principal
amount of such Debt Securities subject to a mandatory sinking fund payment
without the option to deliver or credit Debt Securities as
<PAGE>   32
                                                                              22

provided in this Section 3.05 and without the right to make any optional
sinking fund payment, if any, with respect to such series.

     Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made in cash
which shall equal or exceed $100,000 (or a lesser sum if the Company shall so
request) with respect to the Debt Securities of any particular series shall be
applied by the Trustee on the sinking fund payment date on which such payment
is made (or, if such payment is made before a sinking fund payment date, on the
sinking fund payment date following the date of such payment) to the redemption
of such Debt Securities at the Redemption Price specified in such Debt
Securities, resolution or supplemental Indenture for operation of the sinking
fund together with any accrued interest to the date fixed for redemption.  Any
sinking fund moneys not so applied or allocated by the Trustee to the
redemption of Debt Securities shall be added to the next cash sinking fund
payment received by the Trustee for such series and, together with such
payment, shall be applied in accordance with the provisions of this Section
3.05.  Any and all sinking fund moneys with respect to the Debt Securities of
any particular series held by the Trustee on the last sinking fund payment date
with respect to Debt Securities of such series and not held for the payment or
redemption of particular Debt Securities shall be applied by the Trustee,
together with other moneys, if necessary, to be deposited sufficient for the
purpose, to the payment of the principal of the Debt Securities of that series
at maturity.

     The Trustee shall select the Debt Securities to be redeemed upon such
sinking fund payment date in the manner specified in the last paragraph of
Section 3.02 and the Company shall cause notice of the redemption thereof to be
given in the manner provided in Section 3.02 except that the notice of
redemption shall also state that the Debt Securities are being redeemed by
operation of the sinking fund.  Such notice having been duly given, the
redemption of such Debt Securities shall be made upon the terms and in the
manner stated in Section 3.03.

     At least one business day before each sinking fund payment date, the
Company shall pay to the Trustee in cash a sum equal to any interest accrued to
the date fixed for redemption of Debt Securities or portions thereof to be
<PAGE>   33
                                                                              23

redeemed on such sinking fund payment date pursuant to this Section 3.05.

     The Trustee shall not redeem any Debt Securities of a series with sinking
fund moneys or mail any notice of redemption of such Debt Securities by
operation of the sinking fund for such series during the continuance of a
default in payment of interest on such Debt Securities or of any Event of
Default (other than an Event of Default occurring as a consequence of this
paragraph) with respect to such Debt Securities, except that if the notice of
redemption of any such Debt Securities shall theretofore have been mailed in
accordance with the provisions hereof, the Trustee shall redeem such Debt
Securities if cash sufficient for that purpose shall be deposited with the
Trustee for that purpose in accordance with the terms of this Article Three.
Except as aforesaid, any moneys in the sinking fund for such series at the time
when any such default or Event of Default shall occur and any moneys thereafter
paid into such sinking fund shall, during the continuance of such default or
Event of Default, be held as security for the payment of such Debt Securities;
provided, however, that in case such Event of Default or default shall have
been cured or waived as provided herein, such moneys shall thereafter be
applied on the next sinking fund payment date for such Debt Securities on which
such moneys may be applied pursuant to the provisions of this Section 3.05.

     SECTION 3.06.  Right to Require Repurchase of Debt Securities by the
Company upon Change in Control and Decline in Debt Rating.  (a)  In the event
that (i) there shall occur any Change in Control (as hereinafter defined) and
(ii) the prevailing rating of the Debt Securities by Standard & Poor's
Corporation or its successors ("S&P") or Moody's Investors Service, Inc. or its
successors ("Moody's") or another nationally recognized rating agency selected
by the Company, on any date within 90 days following public notice (as
hereinafter defined) of the occurrence of such Change in Control shall be less
than the rating of the Debt Securities on the date 30 days prior to the
occurrence of such Change in Control by at least one Full Rating Category
("Rating Decline"), each holder of Debt Securities shall have the right, at
such holder's option, to require the Company to purchase, and upon the exercise
of such right the Company shall purchase, all or any part of such holder's Debt
Securities on the date (the "Repurchase Date") that is 100 days after the last
to occur of
<PAGE>   34
                                                                              24

          (i) public notice of such Change in Control and

          (ii) the Rating Decline,

at the Redemption Price in effect on the Repurchase Date, plus any accrued and
unpaid interest to the Repurchase Date.

     (b)  On or before the 28th day following the last to occur of

          (i) public notice of such Change in Control and

          (ii) the Rating Decline,

the Company, or at the written request of the Company, the Trustee, shall give
notice of a Change in Control and Rating Decline and of the repurchase right
set forth herein arising as a result thereof by first-class mail, postage
prepaid, to the Trustee and to each holder of Debt Securities at such holder's
address appearing in the Debt Securities Register; provided that the Trustee
shall not be deemed to have knowledge of such Change in Control and Rating
Decline until such notice is given in writing to the Trustee by the Company.
The Company shall also cause a copy of such notice of a repurchase right to be
published in a newspaper of general circulation in the Borough of Manhattan,
New York.

     Each notice of a repurchase right shall state:

          (1) the Repurchase Date,

          (2) the date by which the repurchase right must be exercised,

          (3) the price at which the repurchase is to be made, if the repurchase
     right is exercised, and

          (4) a description of the procedure which a holder of Debt Securities
     must follow to exercise a repurchase right.

     No failure of the Company to give the foregoing notice shall limit any
holder's right to exercise a repurchase right.

     (c)  To exercise a repurchase right, a holder of Debt Securities shall
deliver to the Company (or an agent designated by the Company for such purpose
in the notice
<PAGE>   35
                                                                              25

referred to in (b) above) at least ten days prior to the Repurchase Date (i)
written notice of the holder's exercise of such right, which notice shall set
forth the name of the holder, the principal amount of the Debt Security or Debt
Securities (or portion of a Debt Security) to be repurchased, and a statement
that the option to exercise the repurchase right is being made thereby, and
(ii) the Debt Security with respect to which the repurchase right is being
exercised, duly endorsed for transfer to the Company.  Such written notice
shall be irrevocable.

     (d)  In the event a repurchase right shall be exercised in accordance with
the terms hereof, the Company shall pay or cause to be paid the price payable
with respect to the Debt Security or Debt Securities as to which the repurchase
right has been exercised in cash to the holder of such Debt Security or Debt
Securities, on the Repurchase Date.  In the event that a repurchase right is
exercised with respect to less than the entire principal amount of a
surrendered Debt Security, the Company shall execute and deliver to the Trustee
and the Trustee shall authenticate for issuance in the name of the holder a new
Debt Security or Debt Securities in the aggregate principal amount of the
unrepurchased portion of such surrendered Debt Security.

     (e) As used in this Section 3.06:

          (1) a "Change of Control" shall be deemed to have occurred at such
     time as (i) a "person" or "group" (within the meaning of Section 13(d) and
     14(d)(2) of the Securities Exchange Act of 1934, as amended) becomes the
     "beneficial owner" (as defined in Rule 13d-3 under such Exchange Act) of
     more than fifty percent (50%) of the then outstanding voting stock of the
     Company, otherwise than through a transaction arranged by, or consummated
     with the prior approval of, the Board of Directors of the Company, or (ii)
     during any period of two consecutive years, individuals who at the
     beginning of such period constitute the Company's Board of Directors
     (together with any new Director whose election by the Company's Board of
     Directors or whose nomination for election by the Company's stockholders
     was approved by a vote of at least two-thirds of the Directors then still
     in office who either were Directors at the beginning of such period or
     whose election or nomination for election was previously so approved)
     cease for any reason to constitute a majority of the Directors then in
     office.
<PAGE>   36
                                                                              26


          (2) the term "Full Rating Category" shall mean (i) with resect to
     S&P, any of the following categories: AAA, AA, A, BBB, BB, B, CCC, CC and
     C, (ii) with respect to Moody's, any of the following categories: Aaa, Aa,
     A, Baa, Ba, B, Caa, Ca and C, (iii) the equivalent of any such category by
     S&P or Moody's and (iv) the equivalent of such ratings by any other
     nationally recognized securities rating agency selected by the Company.
     In determining whether the rating of the Debt Securities has decreased by
     the equivalent of one Full Rating Category, graduation within Full Rating
     Categories (+ and - for S&P; 1, 2 and 3 for Moody's; or the equivalent for
     S&P or Moody's or any such other rating agency) shall be taken into
     account.

          (3)  the term "public notice" shall, without limitation, include any
     filing or report made in accordance with the requirements of the
     Securities and Exchange Commission or any press release or public
     announcement made by the Company.

     (f)  Notwithstanding anything to the contrary contained in this Section
3.06, if a Rating Decline shall apply to less than all series of the Debt
Securities, the repurchase rights described herein shall apply only to the
series with respect to which there has been a Rating Decline.


                                 ARTICLE FOUR.

                      PARTICULAR COVENANTS OF THE COMPANY.

     SECTION 4.01.  Payment of Principal of and Premium, if any, and Interest
on Debt Securities.  The Company, for the benefit of each series of Debt
Securities, will duly and punctually pay or cause to be paid the principal of
and premium, if any, and interest on each of the Debt Securities at the place,
at the respective times and in the manner provided herein and in the Debt
Securities.  Each instalment of interest on the Debt Securities may at the
Company's option be paid by mailing checks for such interest payable to the
person entitled thereto pursuant to Section 2.07 to the address of such person
as it appears on the Debt Security Register.

     SECTION 4.02.  Maintenance of Offices or Agencies for Registration of
Transfer, Exchange and Payment of Debt
<PAGE>   37
                                                                              27

Securities.  As long as any of the Debt Securities remain outstanding, the
Company will maintain one or more offices or agencies in the Borough of
Manhattan, the City and State of New York, where the Debt Securities may be
presented for registration of transfer and exchange as in this Indenture
provided, where the Debt Securities may be presented for payment and where
notices and demands to or upon the Company in respect of the Debt Securities or
of this Indenture may be served.  The Company initially appoints the Trustee
such office or agency.  The Company will give to the Trustee notice of the
location of each such office or agency and of any change of location thereof.
In case the Company shall fail to maintain any such office or agency or shall
fail to give such notice of the location or of any change in the location
thereof, presentations, notices and demands may be made at the principal office
of the Trustee in the Borough of Manhattan, the City and State of New York.

     SECTION 4.03.  Appointment to Fill a Vacancy in the Office of Trustee.
The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so
that there shall at all times be a Trustee hereunder with respect to each
series of Debt Securities.

     SECTION 4.04.  Duties of Paying Agents, etc.  (a) The Company shall cause
each paying agent, if any, other than the Trustee, to execute and deliver to
the Trustee an instrument in which such agent shall agree with the Trustee,
subject to the provisions of this Section 4.04,

          (1) that it will hold all sums held by it as such agent for the
     payment of the principal of and premium, if any, or interest on the Debt
     Securities of any series (whether such sums have been paid to it by the
     Company or by any other obligor on the Debt Securities) in trust for the
     benefit of the Holders of the Debt Securities of such series;

          (2) that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on the Debt Securities) to make any
     payment of the principal of and premium, if any, or interest on the Debt
     Securities of such series when the same shall be due and payable; and

          (3) that it will at any time during the continuance of an Event of
     Default, upon the written
<PAGE>   38
                                                                              28

     request of the Trustee, forthwith pay to the Trustee all sums so held by
     it as such agent.

     (b)  If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of and premium, if any, or interest on
the Debt Securities of any series, set aside, segregate and hold in trust for
the benefit of the Holders of the Debt Securities of such series a sum
sufficient to pay such principal and premium, if any, or interest so becoming
due.  The Company will promptly notify the Trustee of any failure by the
Company to take such action or the failure by any other obligor on such Debt
Securities to make any payment of the principal of and premium, if any, or
interest on such Debt Securities when the same shall be due and payable.

     (c)  Anything in this Section 4.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid
to the Trustee all sums held in trust by it or any paying agent, as required by
this Section 4.04, such sums to be held by the Trustee upon the same trusts as
those upon which such sums were held by the Company or such paying agent.

     (d)  Anything in this Section 4.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 4.04 is subject to
the provisions of Sections 12.03 and 12.04.

     SECTION 4.05.  Statement by Officers as to Default.  The Company will
deliver to the Trustee, on or before a date not more than four months after the
end of each fiscal year of the Company (currently on a calendar year basis)
ending after the date hereof, an Officers' Certificate stating, as to each
officer signing such certificate, whether or not to the best of his knowledge
the Company is in default in the performance and observance of any of the
terms, provisions and conditions hereof, and, if the Company shall be in
default, specifying all such defaults and the nature thereof of which he may
have knowledge.

     SECTION 4.06.  Further Instruments and Acts.  The Company will, upon
request of the Trustee, execute and deliver such further instruments and do
such further acts as may reasonably be necessary or proper to carry out more
effectually the purposes of this Indenture.

                                                                              29


                                 ARTICLE FIVE.

                   HOLDERS' LISTS AND REPORTS BY THE COMPANY
                                AND THE TRUSTEE.

     SECTION 5.01.  Company to Furnish Trustee Information as to Names and
Addresses of Holders.  The Company covenants and agrees that it will furnish or
cause to be furnished to the Trustee with respect to the Debt Securities of
each series:

          (a) not more than 15 days after each record date with respect to the
     payment of interest, if any, a list, in such form as the Trustee may
     reasonably require, of the names and addresses of the Holders as of such
     record date, and

          (b) at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Company of any such request, a list of
     similar form and contents as of a date not more than 15 days prior to the
     time such list is furnished,

provided, however, that so long as the Trustee shall be the Registrar, such
lists shall not be required to be furnished.

     SECTION 5.02.  Preservation of Information; Communications to Holders.
(a) The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of the Holders (1)
contained in the most recent list furnished to it as provided in Section 5.01
or (2) received by it in the capacity of paying agent or Registrar (if so
acting) hereunder.

     The Trustee may destroy any list furnished to it as provided in Section
5.01 upon receipt of a new list so furnished.

     (b)  In case three or more Holders (hereinafter referred to as
"applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Debt Security for a
period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other Holders
of Debt Securities of such series or with Holders of all Debt Securities with
respect to their rights under this Indenture or under such
<PAGE>   40
                                                                              30

Debt Securities, and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee
shall, within five business days after the receipt of such application, at its
election, either

          (1) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with the provisions of subsection (a) of
     this Section 5.02, or

          (2) inform such applicants as to the approximate number of Holders of
     Debt Securities of such series or all Debt Securities whose names and
     addresses appear in the information preserved at the time by the Trustee,
     in accordance with the provisions of subsection (a) of this Section 5.02,
     and as to the approximate cost of mailing to such Holders the form of
     proxy or other communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of a Debt Security of such series or all Debt Securities
whose name and address appears in the information preserved at the time by the
Trustee in accordance with the provisions of subsection (a) of this Section
5.02, a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless within five days after such tender the
Trustee shall mail to such applicants and file with the Securities and Exchange
Commission, together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the Holders of Debt Securities of such
series or all Debt Securities or would be in violation of applicable law.  Such
written statement shall specify the basis of such opinion.  If said Commission,
after opportunity for a hearing upon the objections specified in the written
statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of any order sustaining one or more of such
objections, said Commission shall find, after notice and opportunity for
hearing, that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such

the last report transmitted pursuant to the provisions of subsection (a) of
this Section 5.04 (or if no such report has yet been so transmitted, since the
date of execution of this Indenture), for the reimbursement of which it claims
or may claim a lien or charge prior to that of the Debt Securities on property
or funds held or collected by it as Trustee, and which it has not previously
reported pursuant to this subsection, except that the Trustee shall not be
required (but may elect) to report such advances if such advances remaining

The Company agrees to notify the Trustee when and as the Debt Securities become
listed on any stock exchange.

Company shall solicit from the holders of Debt Securities of any series any
action (including the making of any demand or request, the giving of any
direction, notice, consent or waiver or the taking of any other action), the
Company may, at its option, by resolution of its Board of Directors, fix in
advance a record date for the determination of Holders of Debt Securities
entitled to take such action, but the Company shall have no obligation to do
so.  Any such record date shall be fixed at the Company's discretion.  If such
a record date is fixed, such action may be sought or given before or after the
record date, but only the Holders of Debt Securities of record at the close of
business on such record date shall be deemed to be Holders of Debt Securities
for the purpose of determining whether Holders of the requisite proportion of
Debt Securities of such series Outstanding have authorized or agreed or
consented to such action, and for that purpose the Debt Securities of such
series Outstanding shall be computed as of such record date.

then and in each and every case that an Event of Default described in clauses
(a), (b) or (c) or established pursuant to Section 2.03 with respect to Debt
Securities of any series at the time Outstanding occurs and is continuing,
unless the principal of all the Debt Securities of such series shall have
already become due and payable, either the Trustee or the Holders of not less
than 25 per cent in aggregate principal amount of the Debt Securities of such
series than Outstanding hereunder, by notice in writing to the Company (and to
the Trustee if given by Holders), may declare the principal amount (or, if the
Debt Securities of that series are Original Issue Discount Debt Securities,
such portion of the principal amount as may be specified in the terms of that
series) of all the Debt Securities of such series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything in this Indenture or in the Debt
Securities of such series contained to the contrary notwithstanding.  If an
Event of Default described in clause (d), (e) or (f) occurs and is continuing,
then and in each and every such case, unless the principal of all the Debt
Securities shall have already become due and payable, either the Trustee or the
Holders of not less than 25 per cent in aggregate principal amount of au the
Debt Securities then Outstanding hereunder, by notice in writing to the Company
(and to the Trustee if given by Holders), may declare the principal amount (or,
if any Debt Securities are
<PAGE>   46
                                                                              36

Original Issue Discount Debt Securities, such portion of the principal amount
as may be specified in the terms thereof) of all the Debt Securities then
Outstanding hereunder to be due and payable immediately, and upon any such
condition the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Debt Securities contained to the contrary
notwithstanding.  The foregoing provisions are, however, subject to the
condition that if, at any time after the principal amount (or, if the Debt
Securities of that series are Original Issue Discount Debt Securities, such
portion of the principal amount as may be specified in the terms of that
series) of the Debt Securities of any series (or of all the Debt Securities, as
the case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained
or entered as hereinafter provided, the Company shall pay or shall deposit with
the Trustee a sum sufficient to pay all matured installments of interest upon
all the Debt Securities of such series (or of all the Debt Securities, as the
case may be) and the principal of and premium, if any, on any and all Debt
Securities of such series (or of all the Debt Securities, as the case may be)
which shall have become due otherwise than by acceleration (with interest on
overdue installments of interest, to the extent that payment of such interest
is enforceable under applicable law, and on such principal and premium, if any,
at the rate of interest or Yield to Maturity (in the case of Original Issue
Discount Debt Securities) borne by the Debt Securities of such series (or at
the rates of interest or Yields to Maturity of all the Debt Securities, as the
case may be), to the date of such payment or deposit) and the reasonable
expenses of the Trustee, and any and all defaults under this Indenture, other
than the nonpayment of principal of or premium, if any, or accrued interest on
Debt Securities of such series (or of all the Debt Securities, as the case may
be) which shall have become due by acceleration shall have been remedied then
and in every such case the Holders of a majority in aggregate principal amount
of the Debt Securities of such series (or of all the Debt Securities, as the
case may be) then Outstanding, by written notice to the Company and to the
Trustee, may waive all defaults with respect to such series (or with respect to
all Debt Securities, as the case may be) and rescind and annul such declaration
and its consequences; but no such waiver or rescission and annulment shall
extend or shall affect any subsequent default, or shall impair any right
consequent thereon.

                                                                              37


     In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company and the Trustee shall be restored respectively to their several
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceeding had been
taken.

     SECTION 6.02.  Collection of Indebtedness by Trustee, etc.  The Company
covenants that (1) in case default shall be made in the payment of any
instalment of interest on any of the Debt Securities of any series, as and when
the same shall become due and payable, and such default shall have continued
for a period of 30 days, or (2) in case default shall be made in the payment of
the principal of and premium, if any, on the Debt Securities of any series as
and when the same shall have become due and payable, whether at maturity of the
Debt Securities of that series or upon redemption or by declaration or
otherwise--then, upon demand of the Trustee, the Company will pay to the
Trustee, for the benefit of the Holders of the Debt Securities of that series,
the whole amount that then shall have become due and payable on all such Debt
Securities of that series for principal and premium, if any, or interest, or
both, as the case may be, with interest upon the overdue principal and premium,
if any, and (to the extent that payment of such interest is enforceable under
applicable law) upon overdue installments of interest at the rate or Yield to
Maturity (in the case of Original Issue Discount Debt Securities) borne by the
Debt Securities of that series; and, in addition thereto, such further amount
as shall be sufficient to cover reasonable compensation to the Trustee, its
agents, attorneys and counsel, and all other expenses and liabilities incurred,
and all advances made, by the Trustee except as a result of its negligence or
bad faith.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any
such judgment or final decree against the Company or any other obligor upon
such Debt Securities (and collect in the manner provided by law
<PAGE>   48
                                                                              38

out of the property of the Company or any other obligor upon such Debt
Securities) wherever situated the moneys adjudged or decreed to be payable.

     In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor upon the Debt Securities of
any series under Title 11 of the United States Code or any other Federal or
state bankruptcy, insolvency or similar law, or in case of a receiver, trustee
or other similar official, shall have been appointed for its property, or in
case of any other similar judicial proceedings relative to the Company or any
other obligor upon the Debt Securities of any series, its creditors or its
property, the Trustee, irrespective of whether the principal of Debt Securities
of any series shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have
made any demand pursuant to the provisions of this Section 6.02, shall be
entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal and premium,
if any, and interest (or, if the Debt Securities of that series are Original
Issue Discount Debt Securities, such portion of the principal amount as may be
specified in the terms of that series) owing and unpaid in respect of the Debt
Securities of any series, and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including
any claim for reasonable compensation to the Trustee, its agents, attorneys and
counsel, and for reimbursement of all expenses and liabilities incurred, and
all advances made, by the Trustee except as a result of its negligence or bad
faith) and of the Holders allowed in any such judicial proceedings relative to
the Company, or any other obligor upon the Debt Securities of any series, its
creditors or its property, and to collect and receive any moneys or other
property payable or deliverable on any such claims, and to distribute all
amounts received with respect to the claims of the Holders and of the Trustee
on their behalf, and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the Holders to make payments to
the Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to the Holders, to pay to the Trustee such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other expenses and liabilities incurred, and all
advances

                                                                              39

made, by the Trustee except as a result of its negligence or bad faith.

     All rights of action and of asserting claims under this Indenture, or
under any of the Debt Securities, may be, enforced by the Trustee without the
possession of any of the Debt Securities, or the production thereof on any
trial or other proceedings relative thereto, and any such action or proceedings
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment (except for any amounts payable to
the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the
holders of all the Debt Securities in respect of which such action was taken.

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

     SECTION 6.03.  Application of Moneys Collected by Trustee.  Any moneys
collected by the Trustee, pursuant to Section 6.02, shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such moneys, upon presentation of the several Debt Securities in respect of
which moneys have been collected, and the notation thereon of the payment, if
only partially paid, and upon surrender thereof if fully paid:

          installments of such interest, with interest (to the extent that such
          interest has been collected by the Trustee) upon the overdue
          installments of interest at the rate or

          Yield to Maturity (in the case of Original Issue Discount Debt        
          Securities) borne by the Debt Securities of that series, such
          payments to be made ratably to the persons entitled   
          thereto, without discrimination or preference;

               THIRD:  In case the principal of the Outstanding Debt Securities
          in respect of which such moneys have been collected shall have become
          due, by declaration or otherwise, to the payment of the whole amount
          then owing and unpaid upon the Debt Securities of that series for
          principal and premium, if any, and interest, with interest on the
          overdue principal and premium. if any, and (to the extent that such
          interest has been collected by the Trustee) upon overdue installments
          of interest at the rate or Yield. to Maturity (in the case of
          Original Issue Discount Debt Securities) borne by the Debt Securities
          of that series; and in case such moneys shall be insufficient to pay
          in full the whole amount so due and unpaid upon the Debt Securities
          of that series, then to the payment of such principal and premium, if
          any, and interest, without preference or priority of principal and
          premium, if any, over interest, or of interest over principal and
          premium, if any, or of any instalment of interest over any other
          instalment of interest, or of any Debt Security of that series over
          any Security of that series, ratably to the aggregate of such
          principal and premium, if any, and accrued and unpaid interest; and

               FOURTH:  The remainder, if any, shall be paid to the Company, its
          successors or assigns, or to whomsoever may be lawfully entitled to
          receive the same, or as a court of competent jurisdiction may direct.

     SECTION 6.04.  Limitation on Suits by Holders.  No Holder of any Debt
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise, upon or under or with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless such Holder previously shall have given to the Trustee
written notice of an Event of Default and of the
<PAGE>   51
                                                                              41

continuance thereof and unless the Holders of not less than twenty-five percent
in aggregate principal amount of the outstanding Debt Securities of that
series, or, in the case of any Event of Default described in clause (d), (e) or
(f) of Section 6.01, twenty-five percent in aggregate principal amount of all
Debt Securities then Outstanding, shall have made written request upon the
Trustee to institute such action or proceedings in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby, and the Trustee, for 60 days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such action
or proceedings and no direction inconsistent with such written request shall
have been given to the Trustee pursuant to Section 6.06; it being understood
and intended, and being expressly covenanted by the Holder of every Debt
Security with every other Holder and the Trustee, that no one or more Holders
shall have any right in any manner whatever by virtue or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of any
Holders, or to obtain or seek to obtain priority over or preference to any
other such Holder, or to enforce any right under this Indenture, except in the

premium, if any, and interest on such Debt Security, on or after the respective
due dates expressed in such Debt Security, and to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     SECTION 6.05.  Remedies Cumulative; Delay or Omission in Exercise of
Rights Not a Waiver of Default.  All powers and remedies given by this Article
Six to the Trustee or to the Holders shall, to the extent permitted by law, be

remedies available to the Trustee or the Holders, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and

                                                                              42

Trustee or of any Holder to exercise any right or power accruing upon any
default occurring and continuing as aforesaid, shall impair any such right or
power, or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to the provisions of Section 6.04, every
power and remedy given by this Article Six or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Holders.

      SECTION 6.06.  Rights of Holders of Majority in Principal Amount of Debt
Securities to Direct Trustee and to Waive Default.  The Holders of a majority
in aggregate principal amount of the Debt Securities at the time Outstanding
shall have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee; provided, however, that such direction shall
not be otherwise than in accordance with law and the provisions of this
Indenture, and that subject to the provisions of Section 7.01, the Trustee
shall have the right to decline to follow any such direction if the Trustee
being advised by counsel shall determine that the action so directed may not
lawfully be taken, or if the Trustee shall by a responsible officer or officers
determine that the action so directed would involve it in personal liability or
would be unjustly prejudicial to Holders of Debt Securities not taking part in
such direction; and provided further, that nothing in this Indenture contained
shall impair the right of the Trustee to take any action deemed proper by the
Trustee and which is not inconsistent with such direction by the Holders.
Prior to the declaration of the maturity of the Debt Securities of any series,
or of all the Debt Securities, as the case may be, as provided in Section 6.01,
the Holders of a majority in aggregate principal amount of the Debt Securities
of that series at the time Outstanding may on behalf of the Holders of all of
the Debt Securities of that series waive any past default or Event of Default
described in clause (a), (b) or (c) of Section 6.01, or any other Event of
Default for that series specified in the terms thereof as contemplated by
Section 2.03 (or in the case of an event specified in clause (d), (e) or (f) of
Section 6.01, the Holders of a majority in aggregate principal amount of all
the Debt Securities then Outstanding may waive any such default or Event of
Default), and its consequences, except a default in the payment of the
principal of and premium, if any, or interest on any of the Debt Securities.
In case of any such waiver, the Company,
<PAGE>   53
                                                                              43

the Trustee and the Holders of the Debt Securities of that series, or of all
the Debt Securities, as the case may be, shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend
to any subsequent or other default or impair any right consequent thereon.

     SECTION 6.07.  Trustee to Give Notice of Defaults Known to It, but May
Withhold Such Notice in Certain Circumstances.  The Trustee shall, within 90
days after the occurrence of a default with respect to a series of Debt
Securities, give to the Holders thereof, in the manner provided in subsection
(c) of Section 5.04, notice of all defaults with respect to such series known
to the Trustee, unless such defaults shall have been occurred before the giving
of such notice (the term "default" or "defaults" for the purposes of this
Section 6.07 being hereby defined to be any event or events, as the case may
be, specified in clauses (a), (b), (c), (d), (e) and (f) of Section 6.01, or in
the terms of any Debt Securities pursuant to Section 2.03, not including
periods of grace, if any, provided for therein and irrespective of the giving
of the written notice specified in clause (d) of Section 6.01); provided that,
except in the case of default in the payment of the principal of or premium, if
any, or interest on any of the Debt Securities of such series or in the making
of any sinking fund payment with respect to such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a committee of directors and/or responsible
officers, of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Holders.

     SECTION 6.08.  Requirement of an Undertaking to Pay Costs in Certain Suits
under the Indenture or Against the Trustee.  All parties to this Indenture
agree, and each Holder of any Debt Security by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made
by such party litigant; but the provisions of this Section 6.08 shall not
<PAGE>   54
                                                                              44

apply to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than ten percent in
principal amount of the Outstanding Debt Securities of that series, (or, in the
case of any suit relating to or arising under clause (d), (e) or (f) of Section
6.01, ten percent in principal amount of the Outstanding Debt Securities), or
to any suit instituted by any Holder for the enforcement of the payment of the
principal of or premium, if any, or interest on any Debt Security, on or after
the due date expressed in such Debt Security.


                                 ARTICLE SEVEN.

                            CONCERNING THE TRUSTEE.

     SECTION 7.01.  Certain Duties and Responsibilities.  The Trustee, prior to
the occurrence of an Event of Default and after the curing or waiving of all
Events of Default which may have occurred, undertakes to perform such duties
and only such duties as are specifically set forth in this Indenture.  In case
an Event of Default has occurred (which has not been cured or waived) the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

          (a)  prior to the occurrence of an Event of Default with respect to
     the Debt Securities of a series and after the curing or waiving of all
     Events of Default with respect to such series which may have occurred:

               (1) the duties and obligations of the Trustee with respect to
          Debt Securities of a series shall be determined solely by the express
          provisions of this Indenture, and the Trustee shall not be liable
          except for the performance of such duties and obligations with
          respect to such series as are specifically set forth in this
          Indenture, and no implied covenants or obligations with respect to
<PAGE>   55
                                                                              45

          such series shall be read into this Indenture against the Trustee;

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

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

          (c) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the
     direction of the Holders of not less than a majority in aggregate
     principal amount of the Outstanding Debt Securities relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee,
     under this Indenture.

     None of the provisions of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any personal financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if there shall be reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it.

     SECTION 7.02.  Certain Rights of Trustee.  Except as otherwise provided in
Section 7.01:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond,
<PAGE>   56
                                                                              46

     debenture, note or other paper or document believed by it to be genuine
     and to have been signed or presented by the proper party or parties;

          (b) any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an instrument signed in the name
     of the Company by the Chairman of the Board or the President or a Vice
     President and the Secretary or an Assistant Secretary or the Treasurer or
     an Assistant Treasurer or the Comptroller or an Assistant Comptroller
     (unless other evidence in respect thereof be herein specifically
     prescribed); and any resolution of the Board of Directors of the Company
     may be evidenced to the Trustee by a copy thereof certified by the
     Secretary or an Assistant Secretary of the Company;

          (c) the Trustee may consent with counsel and the advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization
     and protection in respect of any action taken or suffered or omitted by it
     hereunder in good faith and in accordance with such advice or Opinion of
     Counsel;

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

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

          (f) prior to the occurrence of an Event of Default and after the
     curing of all Events of Default which may have occurred, the Trustee shall
     not be bound to make any investigation into the facts or matters stated in
     any resolution, certificate, statement, instrument, opinion, report,
     notice, request, direction, consent, order, approval or other paper or
     document, unless requested in writing to do so by the Holders of a
     majority in aggregate principal amount of the then
<PAGE>   57
                                                                              47

     Outstanding Debt Securities; provided, however, that if the payment within
     a reasonable time to the Trustee of the costs, expenses or liabilities
     likely to be incurred by it in the making of such investigation is not, in
     the opinion of the Trustee, reasonably assured to the Trustee by the
     security afforded to it by the terms of this Indenture, the Trustee may
     require renewable indemnity against such costs, expenses or liabilities as
     a condition to so proceeding.  The reasonable expense of every such
     investigation shall be paid by the Company or, if paid by the Trustee,
     shall be repaid by the Company upon demand;

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

          (h) if any property other than cash shall at any time be subject to a
     lien in favor of the Holders, the Trustee, if and to the extent authorized
     by a receivership or bankruptcy court of competent jurisdiction or by the
     supplemental instrument subjecting such property to such lien, shall be
     entitled to make advances for the purpose of preserving such property or
     of discharging tax liens or other prior liens or encumbrances thereon.

     SECTION 7.03.  Trustee Not Liable for Recitals in Indenture or in Debt
Securities.  The recitals contained herein and in the Debt Securities shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Debt Securities, except that the Trustee represents that it is duly authorized
to execute and deliver this Indenture, authenticate the Debt Securities and
perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility and Qualification on Form T-I supplied to the Company
are true and accurate.  The Trustee shall not be accountable for the use or
application by the Company of any of the Debt Securities or of the proceeds
thereof.

     SECTION 7.04. Trustee, Paying Agent ar Registrar May Own Debt Securities.
The Trustee or any paying agent or
<PAGE>   58
                                                                              48

Registrar, in its individual or any other capacity, may become the owner or
pledgee of Debt Securities and may otherwise deal with the Company with the
same rights it would have if it were not Trustee, paying agent or Registrar.

     SECTION 7.05.  Moneys Received by Trustee To Be Held in Trust.   Subject
to the provisions of Section 12.04, all moneys received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for
which they were received, but need not be segregated from other funds except to
the extent required by law.  The Trustee shall be under no liability for
interest on any moneys received by it hereunder.  So long as no Event of
Default shall have and be continuing, all interest allowed on any such moneys
be paid from time to time upon the written order of the Company, signed by the
Chairman of the Board or the President or a Vice President or its Treasurer or
its Comptroller or an Assistant Treasurer or Assistant Comptroller.

     SECTION 7.06.  Compensation and Reimbursement.  The Company covenants and
agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation for all services rendered by it hereunder
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and, except as otherwise
expressly provided herein, the Company will pay or reimburse the Trustee upon
its request for all reasonable expenses, disbursements and advances incurred or
made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of
its agents, attorneys and counsel and of all  persons not regularly in its
employ) except any such expense, disbursement or advances as may arise from its
negligence or bad faith.  The Company also covenants to indemnify the Trustee
for, and to hold it harmless against, any loss, liability or expense incurred
without negligence or bad faith on the part of the Trustee, arising out of or
in connection with the acceptance or administration of this trust, including
the reasonable costs and expenses of defending itself against any claim of
liability in connection with the exercise or performance of any of its powers
or duties hereunder.  The obligations of the Company under this Section 7.06 to
compensate and indemnity the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional
<PAGE>   59
                                                                              49

indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture.  Such additional indebtedness shall be secured by a lien prior to
that of the Debt Securities upon all property and funds held or collected by
the Trustee, as such, except funds held in trust for the payment of principal
of and premium, if any, or interest on particular Debt Securities.

     SECTION 7.07.  Right of Trustee to Rely on an Officers' Certificate Where
No Other Evidence Specifically Prescribed.  Except as otherwise provided in
Section 7.01, whenever in the administration of the provisions of this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee and such Certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under
the provisions of this Indenture upon the faith thereof.

     SECTION 7.08.  Disqualification; Conflicting Interests. (a) If the Trustee
has or shall acquire any conflicting interest, as defined in this Section 7.08,
it shall, within 90 days after ascertaining that it has such conflicting
interest, either eliminate such conflicting interest or resign in the manner
and with the effect specified in Section 7.10.

     (b)  In the event that the Trustee shall fail to comply with the
provisions of subsection (a) of this Section 7.08, the Trustee shall, within
ten days after the expiration of such 90-day period, transmit notice of such
failure to the Holders, as the names and addresses of such Holders appear upon
the Debt Securities Register.

     (c)  For the purposes of this Section 7.08 the Trustee shall be deemed to
have a conflicting interest with respect to the, Debt Securities of any series
if

          (1) the Trustee is trustee with respect to two or more series of Debt
     Securities or is trustee under another indenture under which any other
     securities, or certificates of interest or participation in any other
<PAGE>   60
                                                                              50

     securities, of the Company, are outstanding, unless such other indenture
     is a collateral trust indenture under which the only collateral consists
     of Debt Securities issued under this Indenture, provided that there shall
     be excluded from the operation of this paragraph (i) the indenture dated
     as of May 1, 1983, relating to the Company's  $100,000,000 8 3/4%
     Convertible Subordinated Debentures Due 2008 and (ii) this Indenture, in
     the event the Trustee is such in respect of two or more series of Debt
     Securities, or any other indenture or indentures under which other
     securities, or certificates of interest or participation in other
     securities of the Company are outstanding if (A) this Indenture and such
     other indenture or indentures are wholly unsecured and such other
     indenture or indentures are hereafter qualified under the Trust Indenture
     Act of 1939, unless the Securities and Exchange Commission shall have
     found and declared by order pursuant to subsection (b) of Section 305 or
     subsection (c) of Section 307 of the Trust Indenture Act of 1939 that
     differences exist between the provisions of this Indenture and the
     provisions of such other indenture or indentures which are so likely to
     involve a material conflict of interest as to make it necessary in the
     public interest or for the protection of investors to disqualify the
     Trustee from acting as such under this Indenture and such other indenture
     or indentures, or (B) the Company shall have sustained the burden of
     proving, on application to the Securities and Exchange Commission and
     after opportunity for hearing thereon, that the trusteeship under this
     Indenture with respect to Debt Securities and such other indenture or
     indentures is not so likely to involve a material conflict of interest as
     to make it necessary in the public interest or for the protection of
     investors to disqualify the Trustee from acting as such under this
     Indenture with respect to Debt Securities and such other indenture or
     indentures;

          (2) the Trustee or any of its directors or executive officers is an
     obligor upon the Debt Securities of any series issued under this Indenture
     or an underwriter for the Company;

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

          (5) ten percent or more of the voting securities of the Trustee is
     beneficially owned either by the Company or by any director, partner, or

     security of an underwriter for the Company;

          (7) the Trustee is the beneficial owner of, or holds as collateral

     aggregate of twenty-five percent or more of the voting securities, or of
     any class of security, of any person, the beneficial ownership of a
     specified percentage of which would have constituted a conflicting
     interest under paragraph (6), (7) or (8) of this subsection (c).  As to
     any such securities of which the Trustee acquired ownership through
     becoming executor, administrator, or testamentary trustee of an estate
     which included them, the provisions of the preceding sentence shall not

     extent that such securities included in such estate do not exceed
     twenty-five percent of such voting securities or twenty-five percent of
     any such class of security.  Promptly after May 15, in each calendar year,
     the Trustee shall make a check of its holdings of such securities in any
     of the above-mentioned capacities as of such May 15.  If the Company fails
     to make payment in full of principal of or interest on any of the Debt
     Securities when and as the same becomes due and payable, and such failure

     as of the date of the expiration of such 30-day period, and after such
     date, notwithstanding the foregoing Provisions of this paragraph (9), all

<PAGE>   63
                                                                              53

     and (8) of this subsection (c).

     The specifications of percentages in paragraphs (5) to (9) inclusive, of

30 days or more and shall not have been cured; and (C) the Trustee shall not be
deemed to be the owner or holder of (i) any security which it holds as
collateral security (as trustee or otherwise) for an obligation which is not in
default as defined in clause (B) above, or (ii) any security which it holds as
collateral security under this Indenture, irrespective of any default
hereunder, or (iii) any security which it holds as agent for collection, or as

capacity.

     whether incorporated or unincorporated, but shall not include the chairman
     of the board of directors.

The percentages of voting securities and other securities specified in this
Section 7.08 shall be calculated in accordance with the following provisions:

          (A) A specified percentage of the voting securities of the Trustee,
     the Company or any other person referred to in this Section 7.08 (each of
     whom is referred to as a "person" in this paragraph) means such amount of

     person.

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

          (C) The term "amount" when used in regard to securities, means the
     principal amount if relating to evidences of indebtedness, the number of

          evidenced by such other class of securities is not in default as to
          principal or interest or otherwise,

               (iii) securities pledged by the issuer thereof as security for an
          obligation of the
<PAGE>   66
                                                                              56

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

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

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

     SECTION 7.09.  Requirements for Eligibility of Trustee.  The Trustee
hereunder shall at all times be a corporation organized and doing business

Columbia, authorized under such laws to exercise corporate trust powers, having
a combined capital and surplus of at least 50 million dollars, subject to
supervision or examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 7.09, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.09, the Trustee shall resign immediately in the
manner and with the effect specified in Section 7.10.

     SECTION 7.10.  Resignation and Removal of Trustee. (a) The Trustee, or any
trustee or trustees hereafter appointed,
<PAGE>   67
                                                                              57

may at any time resign with respect to one or more or all series of Debt
Securities by giving written notice of resignation to the Company and by
mailing notice thereof to the Holders of the applicable series at their
addresses as they shall appear on the Debt Securities register.  Upon receiving
such notice of resignation, the Company shall promptly appoint a successor
trustee by written instrument, in duplicate, executed by order of the Board of
Directors of the Company, one copy of which instrument shall be delivered to
the resigning trustee and one copy to the successor trustee.  If no successor
trustee shall have been so appointed and have accepted appointment within, 30
days after the mailing of such notice of resignation, the resigning trustee may
petition any court of competent jurisdiction for the appointment of a successor
trustee, or any Holder who has been a bona fide holder of a Debt Security or
Debt Securities for at least six months may, subject to the provisions of
Section 6.08, on behalf of himself and all others similarly situated, petition
any such court for the appointment of a successor trustee.  Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

     (b) In case at any time any of the following shall occur

          (1) the Trustee shall fail to comply with the provisions of
     subsection (a) of Section 7.08 after written request therefor by the
     Company or by any Holder who has been a bona fide holder of a Debt
     Security or Debt Securities for at least six months, or

          (2) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 7.09 and shall fail to resign after written request
     therefor by the Company or by any such Holder, or

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

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of
<PAGE>   68
                                                                              58

the Company, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee, or, subject to the provisions of
Section 6.08, any Holder who has been a bona fide holder of a Debt Security or
Debt Securities for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor trustee.  Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

     (c) The Holders of a majority in aggregate principal amount of the Debt
Securities of one or more series (each series voting as a class) or all series
at the time Outstanding may at any time remove the Trustee with respect to the
applicable series or all series, as the case may be, and nominate with respect
to the applicable series, or all series, as the case may be, a successor
trustee by the delivery of written notice to the Trustee so removed, to the
Company and to the successor trustee which shall be deemed appointed as
successor trustee with respect to the applicable series unless within ten days
after such nomination the Company objects thereto, in which case the Trustee so
removed or any Holder of Debt Securities of the applicable series, upon the
terms and conditions and otherwise in subsection (a) of this Section 7.10
provided, may petition any court of competent jurisdiction for the appointment
of a successor trustee with respect to such series.

     (d) Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this Article Seven shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.11.

     SECTION 7.11.  Acceptance by Successor to Trustee.  Any successor trustee
appointed as provided in Section 7.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations with respect to such series of its predecessor hereunder, with like
effect as if originally
<PAGE>   69
                                                                              59

named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of Section 7.06,
execute and deliver an instrument transferring to such successor trustee all
the rights and powers of the trustee so ceasing to act.  Upon request of any
such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such
successor trustee all such rights and powers.  Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 7.06.

     In case of the appointment hereunder of a successor trustee with respect
to the Debt Securities of one or more (but not all) series, the Company, the
predecessor Trustee and each successor trustee with respect to the Debt
Securities of any applicable series shall execute and deliver an indenture
supplemental hereto which shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and
duties of the predecessor Trustee with respect to the Debt Securities of any
series as to which the predecessor Trustee is not retiring shall continue to be
vested in the predecessor Trustee, and shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such trustees co-trustees of the same trust and that each such
trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such trustee.

     No successor trustee shall accept appointment as provided in this Section
7.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 7.11, the Company shall mail notice of the succession of such trustee
hereunder to the Holders of the Debt Securities of any applicable series at
their addresses as they shall appear on the Debt Security Register.  If the
Company fails to mail such notice within
<PAGE>   70
                                                                              60

10 days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company.

     SECTION 7.12.  Successor to Trustee by Merger, Consolidation or Succession
to Business.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation restructuring from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided such corporation
shall be qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the
trust created by this Indenture any of the Debt Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt
the certificate of authentication of any predecessor Trustee, and deliver such
Debt Securities so authenticated; and in case at that time any of the Debt
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Debt Securities either in the name of any predecessor
hereunder or in the name of the successor trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Debt
Securities or in this Indenture provided that the certificate of the Trustee
shall have; provided, however, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Debt Securities in
the name of any predecessor Trustee shall apply only to its successor or
successors by merger, conversion or consolidation.

     SECTION 7.13.  Preferential Collection of Claims against Company.  (a)
Subject to the provisions of subsection (b) of this Section 7.13, if the
Trustee shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company or of any other obligor on the Debt Securities within
four months prior to a default, as defined in subsection (c) of this Section
7.13, or subsequent to such a default, then, unless and until such default
shall be cured, the Trustee shall set apart and hold in a special account for
the benefit of the Trustee individually, the Holders of the Debt Securities and
the
<PAGE>   71
                                                                              61

holders of other indenture securities (as defined in subsection (c) of this
Section 7.13):

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

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

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

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

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

          (C) to realize, for its own account, but only to the extent of the
     claim hereinafter mentioned, upon any property held by it as security for
     any such claim, if such claim was created after the beginning of such four
     months' period and such property was received as
<PAGE>   72
                                                                              62

     security therefor simultaneously with the creation thereof, and if the
     Trustee shall sustain the burden of proving that at the time such property
     was so received the Trustee had no reasonable cause to believe that a
     default as defined in subsection (c) of this Section 7.13 would occur
     within four months; or

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

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

     If the Trustee shall be required to account, the funds and property held
in such special account and the proceeds thereof shall be apportioned between
the Trustee, the Holders and the holders of other indenture securities in such
manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceeding for reorganization under Title 11 of the United
States Code or any other Federal or state bankruptcy, insolvency or similar
law, the same percentage of their respective claims, figured before crediting
to the claim of the Trustee anything on account of the receipt by it from the
Company of the funds and property in such special account and before crediting
to the respective claims of the Trustee, the Holders, and the holders of other
indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization under Title 11
of the United States Code or any other Federal or state bankruptcy, insolvency
or similar law, but after crediting thereon receipts on account of the
indebtedness represented by their respective claims from all sources other than
from such dividends and from the funds and property so held in such special
account.  As used in
<PAGE>   73
                                                                              63

this paragraph, with respect to any claim, the term "dividends" shall include
any distribution with respect to such claim, in bankruptcy or receivership or
in proceedings for reorganization under Title 11 of the United States Code or
any other Federal or state bankruptcy, insolvency or similar law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.  The court in which such bankruptcy, receivership, or proceedings
for reorganization is pending shall have jurisdiction (i) to apportion among
the Trustee, the Holders, and the holders of other indenture securities, in
accordance with the provisions of this paragraph, the funds and property held
in such special account and the proceeds thereof, or (ii) in lieu of such
apportionment, in whole or in part, to give the provisions of this paragraph
due consideration in determining the fairness of the distributions to be made
to the Trustee, the Holders and the holders of other indenture securities with
respect to their respective claims, in which event it shall not be needed to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

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

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

          (ii) such receipt of property or reduction of claim occurred within
     four months after such resignation or removal.
<PAGE>   74
                                                                              64

     (b) There shall be excluded from the operation of subsection (a) of this
Section 7.13 a creditor relationship arising from

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

          (2) advances authorized by a receivership or bankruptcy court of
     competent jurisdiction, or by this Indenture, for the purpose of
     preserving any property which shall at any time be subject to the lien of
     this Indenture or of discharging tax liens or other prior liens or
     encumbrances thereon, if notice of such advance and of the circumstances
     surrounding the making thereof is given to the Holders in the manner
     provided in subsection (e) of Section 5.04;

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

          (4) an indebtedness created as a result of services rendered or
     premises rented; or an indebtedness created as a result of goods or
     securities sold in a cash transaction as defined in subsection (c) of this
     Section 7.13;

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

          (6) the acquisition, ownership, acceptance or negotiation of any
     drafts, bills of exchange, acceptances or obligations which fall within
     the classification of self-liquidating paper as defined in subsection (c)
     of this Section 7.13.

     (c)  As used in this Section 7.13:

          (1)  The term "default" shall mean any failure to make payment in
     full of the principal of or interest upon any of the Debt Securities or
     upon the other
<PAGE>   75
                                                                              65

     indenture securities when and as such principal or interest becomes due

     which the Company is an obligor (as defined in the Trust Indenture Act of
     1939) outstanding under any other indenture (A) under which the Trustee is
     also trustee, (B) which contains provisions substantially similar to the
     provisions of subsection (a) of this Section 7.13, and (C) under which a

                                 ARTICLE EIGHT.

                            CONCERNING THE HOLDERS.

     SECTION 8.01.  Evidence of Action by Holders.  Whenever in this Indenture
it is provided that the Holders of a specified percentage in aggregate
principal amount of the Debt Securities of any or all series may take action
<PAGE>   76
                                                                              66

(including the making of any demand or request, the giving of any direction,
notice, consent or waiver or the taking of any other action) the fact that at
the time of taking any such action the Holders of such specified percentage
have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Holders in person or by agent or proxy
appointed in writing, or (b) by the record of the Holders voting in favor
thereof at any meeting of Holders duly called and held in accordance with the
provisions of Article Nine, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders.

     SECTION 8.02.  Proof of Execution of Instruments and of Holding of Debt
Securities.  Subject to the provisions of Sections 7.01, 7.02 and 9.05, proof
of the execution of any instrument by a Holder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee.

     The ownership of Debt Securities shall be proved by the registers of such
Debt Securities or by a certificate of the Debt Securities Registrar.

     The Trustee may require such additional proof of any matter referred to in
this Section 8.02 as it shall deem necessary.

     The record of any Holders' meeting shall be proved in the manner provided
in Section 9.06.

     SECTION 8.03.  Who May Be Deemed Owner of Debt Securities.  Prior to due
presentment for registration of transfer of any Debt Security, the Company, the
Trustee, any paying agent and any Debt Securities Registrar may deem and treat
the person in whose name any Debt Security shall be registered upon the books
of the Company as the absolute owner of such Debt Security (whether or not such
Debt Security shall be overdue and notwithstanding any notation of ownership or
other writing thereon) for the purpose of receiving payment of or on account of
the principal of and premium, if any, and (subject to Section 2.03) interest on
such Debt Security and for all other purposes, and neither the Company nor the
Trustee nor any paying agent nor any Debt Security Registrar shall be affected
by any notice to the contrary; and all such payments so made to any such Holder
for the time being, or upon his order, shall be valid
<PAGE>   77
                                                                              67

and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for moneys payable upon any such Debt Security.

     SECTION 8.04.  Debt Securities Owned by Company or Controlled or
Controlling Companies Disregarded for Certain Purposes.  In determining whether
the Holders of the requisite aggregate principal amount of Debt Securities have
concurred in any demand, request, direction, notice, consent or waiver under
this Indenture, Debt Securities which are owned by the Company or any other
obligor on the Debt Securities or by any person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any other obligor on the Debt Securities shall be disregarded
and deemed not to be outstanding for the purposes of any such determination,
except that for the purpose of determining whether the Trustee shall be
protected in relying on any such demand, request, direction, notice, consent or
waiver only Debt Securities which the Trustee knows are so owned shall be so
disregarded.  Debt Securities so owned which have been pledged in good faith
may be regarded as Outstanding for the purposes of this Section 8.04 if the
pledge shall establish to the satisfaction of the Trustee the pledgee's right
to vote such Debt Securities and that the pledge is not the Company or any
other obligor on the Debt Securities or a person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any such other obligor.  In the case of a dispute as to such
right, any decision by the Trustee taken upon the advice of counsel shall be
full protection to the Trustee.

     SECTION 8.05.  Instruments Executed by Holders Bind Future Holders.  At
any time prior to (but not after) the evidencing to the Trustee, as provided in
Section 8.01, of the taking of any action by the Holders of the percentage in
aggregate principal amount of the Debt Securities specified in this Indenture
in connection with such action, any Holder of a Debt Security which is shown by
the evidence to be included in the Debt Securities the Holders of which have
consented to such action may, by filing written notice with the Trustee at its
corporate trust office and upon proof of holding as provided in Section 8.02,
revoke such action so far as concerns such Debt Security.  Except as aforesaid
any such action taken by the Holder of any Debt Security shall be conclusive
and binding upon such Holder and upon all future Holders and owners of such
Debt Security, and of any Debt Security issued upon transfer thereof or in
exchange or
<PAGE>   78
                                                                              68

substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon such Debt Security or such other Debt Securities.  Any
action taken by the Holders of the percentage in aggregate principal amount of
the Debt Securities specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and the Holders of
all the Debt Securities.


                                 ARTICLE NINE.

                        HOLDERS' MEETINGS AND CONSENTS.

Holders of Debt Securities of any or all series may be called at any time and
from time to time pursuant to the provisions of this Article Nine for any of
the following purposes:

          (1) to give any notice to the Company or to the Trustee, or to give

     be taken by Holders pursuant to any of the provisions of Article Six;

          (2) to remove the Trustee and appoint a successor trustee pursuant to
     the provisions of Article Seven;

<PAGE>   79
                                                                              69

terms the action proposed to be taken at such meeting, shall be mailed to the
Holders of Debt Securities of each series affected at their addresses as they
shall appear on the Debt Security Register.  Such notice shall be mailed not
less than 20 nor more than 120 days prior to the date fixed for the meeting.

     SECTION 9.03.  Call of Meetings by Company or Holders.  In case at any
time the Company, pursuant to a resolution of its Board of Directors, or the
Holders of at least ten per cent in aggregate principal amount of the
Outstanding Debt Securities of any or all series, shall have requested the
Trustee to call a meeting of Holders of Debt Securities of any or all series to
take any action authorized in Section 9.01 by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after
receipt of such request, then the Company or the Holders, in the amount above
specified, may determine the time and the place in the Borough of Manhattan,
the City and State of New York, for such meeting and may call such meeting by
mailing notice thereof as provided in Section 9.02.

     SECTION 9.04.  Who May Attend and Vote at Meetings.  To be entitled to
vote at any meeting of Holders a person shall (a) be a Holder of one or more
Debt Securities with respect to which meeting is being held; or (b) be a person
appointed by an instrument in writing as proxy by such Holder.  The only
persons who shall be entitled to be present or to speak at any meeting of
Holders shall be the persons entitled to vote at such meeting and their counsel
and any representatives of the Trustee and its counsel and any representatives
of the Company and its counsel.

     SECTION 9.05 . Regulations May Be Made by Trustee.  Notwithstanding any
other provisions of this Indenture, the Trustee may make such reasonable
regulations as it may deem advisable for any meeting of Holders, in regard to
proof of the holding of Debt Securities and of the appointment of proxies, and
in regard to the appointment and duties of inspectors of votes, the submission
and examination of proxies, certificates and other evidence of the right to
vote, and such other matters concerning the conduct of the meeting as it shall
think fit.  Except as otherwise permitted or required by any such regulations,
the holding of Debt Securities shall be proved in the manner specified
<PAGE>   80
                                                                              70

in Section 8.02 and the appointment of any proxy shall be proved in the manner
specified in said Section 8.02.

     The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or
the Holders calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman.  A permanent chairman and a permanent secretary
of the meeting shall be elected by vote of the Holders of a majority in
aggregate principal amount of the Debt Securities represented at the meeting
and entitled to vote.

     Subject to the provisions of Sections 8.04 and 9.04, at any meeting each
Holder or proxy shall be entitled to one vote for each $1,000 principal amount
(in the case of Original Issue Discount Debt Securities, such principal amount
to be determined as provided in the definition of "Outstanding") of Debt
Securities held or represented by him, provided that no vote shall be cast or
counted at any meeting in respect of any Debt Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding.
The chairman of the meeting shall have no right to vote other than by virtue of
Debt Securities held by him or instruments in writing as aforesaid duly
designating him as the person to vote on behalf of other Holders.  At any
meeting of Holders duly called pursuant to the provisions of Section 9.02 or
9.03 the presence of persons holding or representing Debt Securities with
respect to which such meeting is being held in an aggregate principal amount
sufficient to take action on the business for the transaction of which such
meeting was called shall constitute a quorum, but, if less than a quorum be
present, the meeting may be adjourned from time to time by the Holders of a
majority in aggregate principal amount of such Debt Securities represented at
the meeting and entitled to vote, and the meeting may be held as so adjourned
without further notice.

     SECTION 9.06.  Manner of Voting at Meetings and Record To Be Kept.  The
vote upon any resolution submitted to any meeting of Holders of Debt Securities
with respect to which such meeting is being held shall be by written ballots on
which shall be subscribed the signatures of the Holders or proxies and the
identifying number or numbers of the Debt Securities held or represented by
them.  The permanent chairman of the meeting shall appoint two inspectors of
<PAGE>   81
                                                                              71

votes who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting.  A
record in duplicate of the proceedings of each meeting of Holders shall be
prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was mailed as provided in Section 9.02.  The record shall be signed and
verified by the affidavits of the permanent chairman and secretary of the
meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have
attached thereto the ballots voted at the meeting.

     Any record so signed and verified shall be conclusive evidence of the
matter therein stated.

     SECTION 9.07.  Written Consent in Lieu of Meetings.  The written
authorization or consent of the requisite percentage of Holders herein
provided, entitled to vote at any such meeting, evidenced as provided in
Article Eight and filed with the Trustee shall be effective in lieu of a
meeting of Holders, with respect to any matter provided for in this Article
Nine.

     SECTION 9.08.  No Delay of Rights by Meeting.  Nothing in this Article
Nine contained shall be deemed or construed to authorize or permit, by reason
of any call of a meeting of Holders or any rights expressly or impliedly
conferred hereunder to make such call, any hindrance or delay in the exercise
of any right or rights conferred upon or reserved to the Trustee or to the
Holders under any of the provisions of this Indenture or of the Debt
Securities.


                                  ARTICLE TEN.

                            SUPPLEMENTAL INDENTURES.

      SECTION 10.01.  Purposes for Which Supplemental Indenture May Be Entered
into Without Consent of Holders.  The Company, when authorized by a resolution
of its Board of Directors, and the Trustee may from time to time and at any
time, without the consent of Holders, enter into an
<PAGE>   82
                                                                              72

indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act of 1939 as in force at the date of the
execution thereof) for one or more of the following purposes:

          (a) to evidence the succession of another corporation to the Company,
     or successive successions, and the assumption by the successor corporation
     of the covenants, agreements and obligations of the Company pursuant to
     Article Eleven;

          (b)  to add to the covenants of the Company such further covenants,
     restrictions, conditions or provisions for the protection of the Holders
     of all or any series of Debt Securities (and if such covenants are to be
     for the benefit of less than all series of Debt Securities, stating that
     such covenants are expressly being included solely for the benefit of such
     series) as its Board of Directors shall consider to be for the protection
     of the Holders of such Debt Securities, and to make the occurrence, or the
     occurrence and continuance, of a default in any of such additional
     covenants, restrictions, conditions or provisions a default or an Event of
     Default permitting the enforcement of all or any of the several remedies
     provided in this Indenture; provided that in respect of any such
     additional covenant, restriction, condition or provision such supplemental
     indenture may provide for a particular period of grace after default
     (which period may be shorter or longer than that allowed in the case of
     other defaults) or may provide for an immediate enforcement upon such
     default or may limit the remedies available to the Trustee upon such
     default or may limit the right of the Holders of a majority in aggregate
     principal amount of any or all series of Debt Securities to waive such
     default;

          (c) to cure any ambiguity or to correct or supplement any provision
     contained herein or in any supplemental indenture which may be defective
     or inconsistent with any other provision contained herein or in any
     supplemental indenture, to convey, transfer, assign, mortgage or pledge
     any property to or with the Trustee, or to make such other provisions in
     regard to matters or questions arising under this Indenture as shall not
     adversely affect the interests of any Holders;
<PAGE>   83
                                                                              73

          (d) to modify or amend this Indenture in such a manner as to permit
     the qualification of any indenture supplemental hereto under the Trust
     Indenture Act of 1939 as then in effect, except that nothing herein
     contained shall permit or authorize the inclusion in any indenture
     supplemental hereto of the provisions referred to in Section 316(a) (2) of
     the Trust Indenture Act of 1939;

          (e) to provide for the issuance under this Indenture of Debt
     Securities in coupon form (including Debt Securities registrable as to
     principal only) and to provide for exchangeability of such Debt Securities
     with Debt Securities issued hereunder in fully registered form and to make
     all appropriate changes for such purpose; and

          (f) to establish the form or terms of Debt Securities of any series as
     permitted by Sections 2.01 and 2.03.

     The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section
10.01 may be executed by the Company and the Trustee without the consent of the
Holders of any of the Debt Securities at the time Outstanding, notwithstanding
any of the provisions of Section 10.02.

     SECTION 10.02.  Modification of Indenture with Consent of Holders of 66
2/3% in Principal Amount of Debt Securities.  With the consent (evidenced as
provided in Section 8.01) of the Holders of not less than 66 2/3% in aggregate
principal amount of the Outstanding Debt Securities of all series affected by
such supplemental indenture (voting as one class), the Company, when authorized
by a resolution of its Board of Directors, and the Trustee may from time to
time and at any time enter into an indenture or indentures supplemental hereto
(which shall conform to the provisions of the Trust Indenture Act of 1939 as in
force at the date
<PAGE>   84
                                                                              74

of execution thereof) for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner the rights of the Holders
of the Debt Securities of such series; provided that no such supplemental
indenture shall (i) extend the fixed maturity of any Debt Securities, or reduce
the principal amount thereof or any premium thereon or the amount of any
Sinking Fund Payment, or reduce the amount or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption thereof,
without the consent of the Holder of each Debt Security so affected, or (ii)
reduce the aforesaid percentage of Debt Securities, the consent of the Holders
of which is required for any such supplemental indenture, without the consent
of the Holders of each Debt Security so affected.  A supplemental indenture
which changes or eliminates any covenant or other provision of this Indenture
which has been expressly included solely for the benefit of one or more
particular series of Debt Securities, or which modifies the rights of the
Holders of Debt Securities of such series with respect to such covenant or
other provision, shall be deemed not to affect the rights under this Indenture
of the Holders of Debt Securities of any other series.

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

     It shall not be necessary for the consent of the Holders under this
Section 10.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

     SECTION 10.03.  Effect of Supplemental Indentures.  Upon the execution of
any supplemental indenture pursuant to the provisions of this Article Ten, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights,
<PAGE>   85
                                                                              75

obligations, duties and immunities under this Indenture of the Trustee, the
Company and the Holders shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments, and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

     The Trustee, subject to the provisions of Sections 7.01 and 7.02, may
receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such supplemental indenture complies with the provisions of
this Article Ten.

     SECTION 10.04.  Debt Securities May Bear Notation of Changes by
Supplemental Indentures.  Debt Securities authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article Ten may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture.  New Debt Securities so modified as to conform, in the opinion of
the Trustee and the Board of Directors of the Company, to any modification of
this Indenture contained in any such supplemental indenture may be prepared and
executed by the Company, authenticated by the Trustee and delivered in exchange
for the Debt Securities then outstanding.


                                ARTICLE ELEVEN.

                   CONSOLIDATION, MERGER, SALE OR CONVEYANCE.

      SECTION 11.01.  Consolidations and Mergers of Company and Conveyances
Permitted Subject to Certain Conditions.  The Company may consolidate with, or
sell or convey all or substantially all its assets to, or merge with or into
any other corporation, provided that in any such case, (i) the successor
corporation shall be a corporation organized and existing under the laws of the
United States of America or a State thereof or the District of Columbia and
such corporation shall expressly assume the due and punctual payment of the
principal of and premium, if any, and interest on all the Debt Securities,
according to their tenor, and the due and punctual performance and observance
of all of the covenants and conditions of this Indenture to be performed by the
Company by supplemental indenture satisfactory to the Trustee, executed and
delivered to the
<PAGE>   86
                                                                              76

Trustee by such corporation, and (ii) such successor corporation shall not,
immediately after such merger or consolidation or such sale or conveyance, be
in
default in the performance of any such covenant or condition.

     SECTION 11.02.  Rights and Duties of Successor Corporation.  In case of
any such consolidation, merger, sale or conveyance  and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it
had been named herein as the party of the first part and the predecessor
corporation shall be relieved of any further obligation under this Indenture.
Such successor corporation thereupon may cause to be signed, and may issue
either in its own name or in the name of the Company, any or all the Debt
Securities issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee; and, upon the order of such successor
corporation, instead of the Company, and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate
and shall deliver any Debt Securities which previously shall have been signed
and delivered by the officers of the Company to the Trustee for authentication,
and any Debt Securities which such successor corporation thereafter shall cause
to be signed and delivered to the Trustee for that purpose.  All the Debt
Securities so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Debt Securities theretofore or thereafter issued in
accordance with the terms of this Indenture as though all such Debt Securities
had been issued at the date of the execution hereof.

     In case of any consolidation, merger, sale or conveyance such changes in
phraseology and form (but not in substance) may be made in the Debt Securities
thereafter to be issued as may be appropriate.

     SECTION 11.03.  Officers' Certificate and Opinion of Counsel.  The
Trustee, subject to the provisions of Sections 7.01 and 7.02, may receive an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that any
such consolidation, merger, sale or conveyance, and any such assumption,
complies with the provisions of this Article Eleven.

     SECTION 12.01.  Satisfaction and Discharge of Indenture.  If at any time
(a) the Company shall have delivered to the Trustee for cancellation all Debt
Securities theretofore authenticated and delivered (other than any Debt
Securities which shall have been destroyed, lost or stolen and which shall have
been replaced or paid as provided in Section 2.09 or Debt Securities for whose
payment money has theretofore been deposited in trust and thereafter repaid to
the Company as provided in Section 12.04), or (b) all such Debt Securities not
theretofore delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee as trust funds the entire amount sufficient to pay at
maturity or upon redemption all such Debt Securities not theretofore delivered
to the Trustee for cancellation, including principal and premium, if any, and
interest due or to become due on such date of maturity or redemption date, as
the case may be, and if in either case the Company shall also pay or cause to
be paid all other sums payable hereunder by the Company, then this Indenture
shall cease to be of further effect, and the Trustee, on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture.

     SECTION 12.02.  Application by Trustee of Funds Deposited for Payment of
Debt Securities.  All moneys deposited with the Trustee pursuant to Section
12.01 shall be held in trust and applied by it to the payment, either directly
or through any paying agent (including the Company acting as its own paying
agent), to the Holders of the particular Debt Securities for the payment of
which such moneys have been deposited with the Trustee, of all sums due and to
become due thereon for principal and interest and premium, if any.

     SECTION 12.03.  Repayment of Moneys Held by Paying Agent.  In connection
with the satisfaction and discharge of

                                                                              78

this Indenture all moneys then held by any paying agent, together with
applicable interest as may have been agreed upon by the Company, if any (other
than the Trustee, if the Trustee be a paying agent) under the provisions of
this Indenture shall, upon demand of the Company, be repaid to it or paid to
the Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys.

     SECTION 12.04.  Repayment of Moneys Held by Trustee.  Any moneys deposited
with the Trustee or any paying agent for the payment of the principal of and
premium, if any, or interest on any Debt Securities of any series and not
applied but remaining unclaimed by the Holders of Debt Securities of that
series for two years after the date upon which the principal of and premium, if
any, or interest on such Debt Securities shall have become due and payable,
shall be repaid to the Company by the Trustee or such paying agent on demand;
and the Holder of any of the Debt Securities entitled to receive such payment
shall thereafter look only to the Company for the payment thereof and all
liability of the Trustee or such paying agent with respect to such moneys shall
thereupon cease; provided, however, that the Trustee or such paying agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published in an Authorized Newspaper, a notice that said
moneys have not been so applied and that after a date named therein any
unclaimed balance of said moneys then remaining will be returned to the
Company.


                               ARTICLE THIRTEEN.

                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                       OFFICERS, DIRECTORS AND EMPLOYEES.

     SECTION 13.01.  Incorporators, Stockholders, Officers, Directors and
Employees of Company Exempt from Individual Liability.  No recourse under or
upon any obligation, covenant or agreement of this Indenture, or of any Debt
Security or for any claim based thereon or otherwise in respect thereof, shall
be had against any incorporator, stockholder, officer, director or employee, as
such, past, present or future, of the Company or of any successor corporation,
either directly or through the Company, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that this Indenture and the
<PAGE>   89
                                                                              79

obligations issued hereunder are solely corporate obligations, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, stockholders, officers, directors or employees, as such, of the
Company or of any successor corporation, of any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any of
the Debt Securities or implied therefrom; and that any and all such personal
liability, either at common law or in equity or by constitution or statute, of,
and any and all such rights and claims against, every such incorporator,
stockholder, officer, director or employee, as such, because of the creation of
the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any of the Debt
Securities or implied therefrom, are hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of such Debt Securities.


                               ARTICLE FOURTEEN.

                       SUBORDINATION OF DEBT SECURITIES.

     SECTION 14.01.  Debt Securities Subordinate to Superior Indebtedness.  The
Company, for itself, its successors and assigns, covenants and agrees, and each
Holder of Debt Securities, by his acceptance thereof, likewise covenants and
agrees, that all Debt Securities issued hereunder shall be subordinated and
subject, to the extent and in the manner herein set forth, in right of payment
to the prior payment in full of all Superior Indebtedness.  The provisions of
this Article are made for the benefit of all holders of Superior Indebtedness,
and any such holder may proceed to enforce such provisions.

     For purposes of this Section "payment in full", as used with respect to
Superior Indebtedness, means the receipt of cash or securities (taken at their
fair value at the time of receipt, determined as hereinafter provided) of the
principal amount of the Superior Indebtedness and premium, if any, and interest
thereon to the date of such payment.  "Fair value" means (i) if the securities
are quoted on a nationally recognized securities exchange, the closing price on
the day such securities are received or, if there are no sales reported on that
day, the reported closing bid price
<PAGE>   90
                                                                              80

on that day, and (ii) if the securities are not so quoted, a price determined
by a nationally recognized investment banking house selected by the Holders of
Debt Securities and the holders of Superior Indebtedness receiving such
securities, such price to be determined as of the date of receipt of such
securities by the holders of Superior Indebtedness.

     SECTION 14.02.  Payment Over of Proceeds Upon Dissolution, etc.  No
payment by the Company on account of principal of or premium, if any, or
interest on the Debt Securities (including sinking fund payments) shall be made
if any default or event of default with respect to any Superior Indebtedness,
which permits or with the giving of notice or passage of time or both would
permit the holders thereof (or a trustee on their behalf) to accelerate the
maturity thereof, shall have occurred and be continuing and (unless such
default or event of default is the failure by the Company to pay principal or
interest on any instrument constituting Superior Indebtedness) the Company and
the Trustee shall have received written notice thereof from the holders of at
least 10% in principal amount of any kind or category of any Superior
Indebtedness (or the representative or trustee of such holders) or the Trustee
shall have received written notice thereof from the Company; provided, however,
that (i) if the Company receives any such notice, a similar notice received
within nine months thereafter relating to the same default on the same issue of
Superior Indebtedness shall not be effective for purposes of this Section, and
(ii) the Company may resume payments on the Debt Securities (unless otherwise
prohibited by this Article) if (a) the default is cured or waived or (b) unless
such default or event of default is the failure by the Company to pay principal
or interest on any investment constituting Superior Indebtedness, 120 days pass
after the notice is given if the default is not the subject of judicial
proceedings.

     In the event that any Debt Security is declared due and payable before the
date specified therein as the fixed date on which the principal thereof is due
and payable, or upon any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding up or liquidation or reorganization of the
Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal of (and premium, if any) and
interest due or to become due upon all
<PAGE>   91
                                                                              81

Superior Indebtedness shall first be paid in full before the Holders of Debt
Securities, or the Trustee, shall be entitled to receive or retain any assets
(other than shares of stock of the Company as reorganized or readjusted or
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment, the payment of which is subordinated, at least
to the same extent as the Debt Securities, to the payment of all Superior
Indebtedness which may at the time be outstanding, provided that the rights of
the holders of the Superior Indebtedness are not altered by such reorganization
or readjustment without the consent of such holders) so paid or distributed in
respect of the Debt Securities (for principal, premium, if any, or interest);
and upon such dissolution or winding up or liquidation or reorganization any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than shares of stock of the
Company as reorganized or readjusted or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated, at least to the same extent as the Debt
Securities, to the payment of all Superior Indebtedness which may at the time
be outstanding, provided that the rights of the holders of the Superior
Indebtedness are not altered by such reorganization or readjustment without the
consent of such holders), to which the Holders of Debt Securities or the
Trustee would be entitled, except for the provisions of this Section, shall be
paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, or by the
Holders of Debt Securities or the Trustee if received by them or it; directly
to the holders of Superior Indebtedness (pro rata to each such holder on the
basis of the respective amounts of Superior Indebtedness held by such holder)
or their representatives or trustees, to the extent necessary to pay all
Superior Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Superior Indebtedness, before any payment
or distribution is made to the Holders of Debt Securities or to the Trustee.

     No holder of Superior Indebtedness shall be prejudiced in his right to
enforce subordination of the Debt Securities by any act or failure to act on
the part of the Company.

     Without notice to or the consent of the Holders of Debt Securities or the
Trustee, the holders of Superior Indebtedness may at any time and from time to
time, without
<PAGE>   92
                                                                              82

impairing or releasing the subordination herein made, change the manner, place
or terms of payment, or change or extend the time of payment of or renew or
alter the Superior Indebtedness, or amend or supplement in any manner any
instrument evidencing the Superior Indebtedness, any agreement pursuant to
which the Superior Indebtedness was issued or incurred or any instrument
securing or relating to the Superior Indebtedness; release any person liable in
any manner for the payment or collection of the Superior Indebtedness; exercise
or refrain from exercising any rights in respect of the Superior Indebtedness
against the Company or any other person; apply any moneys or other property
paid by any person or rely in any manner to the Superior Indebtedness; or
accept or release any security for the Superior Indebtedness.

     Subject to the payment in full of all Superior Indebtedness, the Holders
of Debt Securities shall be subrogated (equally and ratably with the holders of
all indebtedness of the Company which, by its express terms, ranks on a parity
with the Debt Securities and is entitled to like rights of subrogation) to the
rights of the holders of Superior Indebtedness to receive payments or
distribution of assets of the Company applicable to the Superior Indebtedness
until the Debt Securities shall be paid in full.  For purposes of such
subrogation, no payments or distributions on the Superior Indebtedness pursuant
to this Section shall, as between the Company, its creditors other than the
holders of Superior Indebtedness, and the Holders of Debt Securities, be deemed
to be a payment by the Company to or on amount of the Superior Indebtedness,
and no payments or distributions to the Trustee or the Holders of Debt
Securities of assets by virtue of the subrogation herein provided for shall, as
between the Company, its creditors other than the holders of Superior
Indebtedness, and the Holders of Debt Securities, be deemed to be a payment to
or on account of the Debt Securities.  The provisions of this Article are and
are intended solely for the purpose of defining the relative rights of the
Holders of Debt Securities, on the one hand, and the holders of Superior
Indebtedness, on the other hand, and nothing contained in this Article or
elsewhere in this Indenture or in the Debt Securities is intended to or shall
impair the obligation of the Company, which is unconditional and absolute, to
pay the principal of and premium, if any, and interest on the Debt Securities
as and when the same shall become due and payable in accordance with their
terms, or to affect the relative rights of the Holders of Debt Securities
<PAGE>   93
                                                                              83

and creditors of the Company other than the holders of Superior Indebtedness,
nor shall anything herein or therein prevent the Trustee or the Holder of any
Debt Security from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture, subject to the rights, if any, under
this Article, of the holders of Superior Indebtedness in respect of cash,
property or securities of the Company otherwise payable or delivered to the
Trustee or such Holder of Debt Securities upon the exercise of any such remedy.

     Upon any payment or distribution pursuant to this Section, the Trustee and
the Holders of Debt Securities shall be entitled to rely upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in this Section are pending, and the Trustee, subject to the
provisions of Section 7.01, and the Holders of Debt Securities shall be
entitled to rely upon a certificate of the liquidating trustee or agent or
other person making such payment or distribution delivered to the Trustee or to
the Holders of Debt Securities, for the purpose of ascertaining the persons
entitled to participate in such payments or distribution, the holders of
Superior Indebtedness and other indebtedness of the Company, the amount thereof
or payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this Section.  In the event that the
Trustee determines, in good faith, that evidence is required with respect to
the right of any person as a holder of Superior Indebtedness to participate in
any payment or distribution pursuant to this Section, the Trustee may request
such person to furnish evidence to the renewable satisfaction of the Trustee as
to the amount of Superior Indebtedness held by such person, as to the extent to
which such person is entitled to participate in such payment or distribution,
and as to other facts pertinent to the rights of such person under this
Section, and if such evidence is not furnished, the Trustee may defer any
payment to such person pending judicial determination as to the right of such
person to receive such payment.

     Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Debt Securities, shall prevent the application by the Trustee or any
paying agent of any moneys deposited with it hereunder to the payment of or on
account of the principal of and premium, if any, or interest on Debt Securities
if, at the time of such deposit (provided that the time of such deposit was not
more than ten days
<PAGE>   94
                                                                              84

prior to the time of such payment), the Trustee or such paying agent, as the
case may be, did not have written notice of any event prohibiting the making of
such deposit by the Company.

     SECTION 14.03.  Trustee to Effectuate Subordination.  The Holder of each
Debt Security by his acceptance thereof authorizes and directs the Trustee in
his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Holders of Debt
Securities and the holders of Superior Indebtedness as provided in this Article
and appoints the Trustee as attorney-in- fact for any and all such purposes.

     SECTION 14.04.  Trustee Not Charged with Knowledge of Prohibition.
Notwithstanding the provisions of this Article or any other provision of this
Indenture, but subject to the provisions of Section 7.01, the Trustee and any
paying agent shall not be charged with knowledge of the existence of any
Superior Indebtedness, or of any default in the payment of the principal of (or
premium, if any) or interest on any Superior Indebtedness, or of any facts
which would prohibit the making of any payment of moneys to or by the Trustee
or any such paying agent, unless and until the Trustee or such paying agent
shall have received written notice thereof from the Company or the holders of
at least ten percent in principal amount of any kind or category of any
Superior Indebtedness or the representative or trustee of such holders
(provided, however, that notwithstanding the foregoing, in the event of any
default in the payment of principal of (or premium, if any) or interest on any
Superior Indebtedness, such written notice may be given by any holder of
Superior Indebtedness or the representative or trustee of such holder); nor
shall the Trustee or any such paying agent be charged with knowledge of the
curing of any such default or of the elimination of the act or condition
preventing any such payment unless and until the Trustee or such paying agent
shall have received an Officers' Certificate to such effect.

     SECTION 14.05.  Rights of Trustee as Holder of Superior Indebtedness.  The
Trustee shall be entitled to all the rights set forth in this Article with
respect to any Superior Indebtedness which may at any time be held by it, to
the same extent as any other holder of Superior Indebtedness; and nothing
elsewhere in this Indenture shall deprive the Trustee of any of its rights as
such holder.
<PAGE>   95
                                                                              85

Nothing in this Article shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 7.06.

     SECTION 14.06.  Trustee Not Fiduciary for Holders of Superior
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Superior Indebtedness and shall not be liable to any such holders if
it shall mistakenly pay over or distribute to any Holder of Debt Securities or
the Company or any other person moneys or assets to which any holders of
Superior Indebtedness shall be entitled by virtue of this Article or otherwise.

     SECTION 14.07.  Article Applicable to Paying Agents.  In case at any time
any paying agent other than the Trustee shall have been appointed by the
Company and be acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context shall otherwise require) be construed as
extending to and including such paying agent within its meaning as fully for
all intents and purposes as if such paying agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Sections 14.04,
14.05, 14.06 and 14.08 shall not apply to the Company if it acts as paying
agent.

     SECTION 14.08.  Rights of Trustee.  Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment or distribution by the Trustee, or the taking of any
action by the Trustee, and the Trustee may continue to make payments on the
Debt Securities, unless it shall have received at the Corporate Trust Office of
the Trustee at least three Business Days prior to the date of such payment
written notice (including, without limitation, hand delivery, telex, telegram,
or any other form of electronic transmission) of facts that would cause the
payment of any obligations with respect to the Debt Securities to violate this
Article.  Such notice to the Trustee is deemed given when received.  Only the
Company, a representative or trustee of holders of an issue of Superior
Indebtedness or a holder of an issue of Superior Indebtedness that has no
representative or trustee may give such notice.

         of such series or any portion thereof, in either case having the same
         terms, including, without limitation, the same original issue date,

         B.      Section 2.03 of the Original Indenture is amended to (i)
redesignate paragraph (13) as paragraph (14) and (ii) add a new paragraph (13)
as follows:

                 "(13) If the Debt Securities of the series shall be issued in

         Securities may be exchanged in whole or in part for other individual
         Debt Securities in definitive registered form; and the Depositary for
         such Global Security or Securities; and"

         C.      Article Two of the Original Indenture is amended to add a new
Section 2.15, which reads in its entirety as follows:

                 SECTION 2.15.  Securities Issuable in the Form of a Global
         Security.  (a) If the Company shall establish pursuant to Sections
         2.01 and 2.03 that the Debt Securities of a particular series are to
         be issued in whole or in part in the form of one or more Global
         Securities, then the Company shall execute and the Trustee or its
         agent shall, in accordance with Section 2.05, authenticate and
         deliver, such Global Security or Securities, which (i) shall
         represent, and shall be denominated in an amount equal to the
         aggregate principal amount of, the Outstanding Debt Securities of such
         series to be represented by such Global Security or Securities, or
         such portion thereof as the Company shall specify in an Officer's
         Certificate, (ii) shall be registered in the name of the Depositary
         for such Global Security or Securities or its nominee, (iii) shall be
         delivered by the Trustee or its agent to the Depositary or pursuant to
         the Depositary's instruction and (iv) shall bear a legend
         substantially to the following effect:  'Unless and until it is
         exchanged in whole or in part for the individual Debt Securities
         represented hereby, this Global Security may not be transferred except
         as a whole by the Depositary to a nominee of the Depositary or by a
         nominee of the Depositary to the Depositary or another nominee of the
         Depositary or by the Depositary or any such nominee to a successor
         Depositary or a nominee of such successor
<PAGE>   4
                                      -4-

         Depositary, or such other legend as may then be required by the
Depositary for such Global Security or Securities.

                 (b)      Notwithstanding any other provision of this Section
         2.15 or of Section 2.07 to the contrary, and subject to the provisions
         of paragraph (c) below, unless the terms of a Global Security
         expressly permit such Global Security to be exchanged in whole or in
         part for definitive Debt Securities in registered form, a Global
         Security may be transferred, in whole but not in part and in the
         manner provided in Section 2.07, only by the Depositary to a nominee
         of the Depositary for such Global Security, or by a nominee of the
         Depositary to the Depositary or another nominee of the Depositary, or
         by the Depositary or a nominee of the Depositary to a successor
         Depositary for such Global Security selected or approved by the
         Company, or to a nominee of such successor Depositary.

                 (c)      (i)     If at any time the Depositary for a Global
         Security or Securities notifies the Company that it is unwilling or
         unable to continue as Depositary for such Global Security or
         Securities or if at any time the Depositary for the Debt Securities
         for such series shall no longer be eligible or in good standing under
         the Securities Exchange Act of 1934, as amended, or other applicable
         statute or regulation, the Company shall appoint a successor
         Depositary with respect to such Global Security or Securities.  If a
         successor Depositary for such Global Security or Securities is not
         appointed by the Company within 90 days after the Company receives
         such notice or becomes aware of such ineligibility, the Company will
         execute, and the Trustee or its agent, upon receipt of a written order
         of the Company signed by its Chairman of the Board or its President or
         a Vice President and by its Treasurer or its Controller or its
         Secretary or an Assistant Treasurer or an Assistant Controller or an
         Assistant Secretary for the authentication and delivery of individual
         Debt Securities of such series in exchange for such Global Security,
         will authenticate and deliver, individual Debt Securities of such
         series of like tenor and terms in definitive form in an aggregate
         principal amount equal to the principal amount of the Global Security
         in exchange for such Global Security or Securities.

                 (ii)     The Company may at any time and in its sole
         discretion determine that the Debt Securities of any series or portion
         thereof issued or issuable in the form of one or more Global
         Securities shall no longer be represented by such Global Security or
         Securities.
<PAGE>   5
                                      -5-

         In such event the Company will execute, and the Trustee, upon receipt
         of a written order of the Company, signed by its Chairman of the Board
         or any Vice Chairman or its President or a Vice President and by its
         Treasurer or its Controller or its Secretary or an Assistant Treasurer
         or an Assistant Controller or Assistant Secretary, for the
         authentication and delivery of individual Debt Securities of such
         series in exchange in whole or in part for such Global Security, will
         authenticate and deliver individual Debt Securities of such series of
         like tenor and terms in definitive form in an aggregate principal
         amount equal to the principal amount of such series or portion thereof
         in exchange for such Global Security or Securities.

                 (iii) If specified by the Company pursuant to Sections 2.01
         and 2.03 with respect to Debt Securities issued or issuable in the
         form of a Global Security, the Depositary for such Global Security may
         surrender such Global Security in exchange in whole or in part for
         individual Debt Securities of such series of like tenor and terms in
         definitive form on such terms as are acceptable to the Company, the
         Trustee and such Depositary.  Thereupon the Company shall execute, and
         the Trustee or its agent upon receipt of a written order by the
         Company, signed by its Chairman of the Board or any Vice Chairman or
         its President or a Vice President and by its Treasurer or its
         Controller or its Secretary or an Assistant Treasurer or an Assistant
         Controller or Assistant Secretary, for the authentication and delivery
         of definitive Debt Securities of such series shall authenticate and
         deliver, without service charge, (1) to each person specified by such
         Depositary a new Debt Security or Securities of the same series of
         like tenor and terms and of any authorized denomination as requested
         by such person in aggregate principal amount equal to and in exchange
         for such person's beneficial interest in the Global Security; and (2)
         to such Depositary a new Global Security of like tenor and terms and
         in an authorized denomination equal to the difference, if any, between
         the principal amount of the surrendered Global Security and the
         aggregate principal amount of Debt Securities delivered to Holders
         thereof.

                 (iv)     In any exchange provided for in any of the preceding
         three paragraphs, the Company will execute and the Trustee or its
         agent will authenticate and deliver individual Debt Securities in
         definitive registered form in authorized denominations.  Upon the
<PAGE>   6
                                      -6-

         exchange of the entire principal amount of a Global Security for
         individual Debt Securities, such Global Security shall be cancelled by
         the Trustee or its agent.  Except as provided in the preceding
         paragraph, Debt Securities issued in exchange for a Global Security
         pursuant to this Section shall be registered in such names and in such
         authorized denominations as the Depositary for such Global Security,
         pursuant to instructions from its direct or indirect participants or
         otherwise, shall instruct the Trustee or the Registrar.  The Trustee
         or the Registrar shall deliver such Debt Securities to the Persons in
         whose names such Debt Securities are so registered."

         D.      The first paragraph of Section 2.07 of the Original Indenture
is amended to add the words "Subject to Section 2.15," before the word "Upon"
in the third sentence of such paragraph.

         E.      The third paragraph of Section 2.07 of the Original Indenture
is amended to add the words "Subject to Section 2.15," before the word "Debt"
in the second sentence of such paragraph.

         F.      The following paragraph is added at the end of Section 2.07 of
the Original Indenture:

                 "None of the Company, the Trustee, any agent of the Trustee,
         any paying agent or any Registrar will have any responsibility or
         liability for any aspect of the records relating to, or payments made
         on account of beneficial ownership interests of a Global Security or
         for maintaining, supervising or reviewing any records relating to such
         beneficial ownership interests."

         G.      Article Two of the Original Indenture is amended to add a new
Section 2.16 which reads in its entirety as follows:

                 "Section 2.16.  Medium-term Securities.  Notwithstanding any
         contrary provision herein, if all Debt Securities of a series are not
         to be originally issued at one time, it shall not be necessary for the
         Company to deliver to the Trustee an Officers' Certificate,
         resolutions of the Board of Directors, supplemental indenture, Opinion
         of Counsel or written order or any other document otherwise required
         pursuant to Sections 2.01, 2.03, 2.05 or 14.05 at or prior to the time
         of authentication of each Debt Security of such series if such
         documents are delivered to the Trustee or its agent at or prior to the
         authentication
<PAGE>   7
                                      -7-

         upon original issuance of the first such Debt Security of such series
         to be issued; provided that any subsequent request by the Company to
         the Trustee to authenticate Debt Securities of such series upon
         original issuance shall constitute a representation and warranty by
         the Company that as of the date of such request, the statements made
         in the Officers' Certificate delivered pursuant to Section 2.05 or
         14.05 shall be true and correct as if made on such date and that the
         Opinion of Counsel delivered at or prior to such time of
         authentication of an original issuance of Debt Securities shall
         specifically state that it shall relate to all subsequent issuances of
         Debt Securities of such series that are identical to the Debt
         Securities issued in the first issuance of Debt Securities of such
         series.

                 A written order of the Company signed by its Chairman of the
         Board or its President or a Vice President and by its Treasurer or its
         Controller or its Secretary or an Assistant Treasurer or an Assistant
         Controller or an Assistant Secretary, delivered by the Company to the
         Trustee in the circumstances set forth in the preceding paragraph may
         provide that Debt Securities which are the subject thereof will be
         authenticated and delivered by the Trustee or its agent on original
         issue from time to time upon the telephonic or written order of
         persons designated in such written order (any such telephonic
         instructions to be promptly confirmed in writing by such person) and
         that such persons are authorized to determine, consistent with the
         Officers' Certificate, supplemental indenture or resolution of the
         Board of Directors relating to such written order, such terms and
         conditions of said Securities as are specified in such Officers'
         Certificate, supplemental indenture or such resolution."

         H.      Article Five of the Original Indenture is amended to add a new
Section 5.05 which reads in its entirety as follows:

                 "SECTION 5.05.  Record Dates for Action by Holders.  If the
Company shall solicit from the holders of Debt Securities of any series any
action (including the making of any demand or request, the giving of any
direction, notice, consent or waiver or the taking of any other action), the
Company may, at its option, by resolution of its Board of Directors, fix in
advance a record date for the determination of Holders of Debt Securities
entitled to take such action, but the Company
<PAGE>   8
                                      -8-

shall have no obligation to do so.  Any such record date shall be fixed at the
Company's discretion.  If such a record date is fixed, such action may be
sought or given before or after the record date, but only the Holders of Debt
Securities of record at the close of business on such record date shall be
deemed to be Holders of Debt Securities for the purpose of determining whether
Holders of the requisite proportion of Debt Securities of such series
Outstanding have authorized or agreed or consented to such action, and for that
purpose the Debt Securities of such series Outstanding shall be computed as of
such record date."

         I.      The fourth paragraph of Section 3.02 of the Original Indenture
is amended to add the words "of like tenor and terms" after the words "than all
the Debt Securities" and before the words "of any series" in the first sentence
of such paragraph.

         J.      The fourth paragraph of Section 3.02 of the Original Indenture
is further amended to add, after that last sentence of such paragraph, the
following:

                 "If less than all the Debt Securities of unlike tenor and
terms of a series are to be redeemed, the particular Debt Securities to be
redeemed shall be selected by the Company."

                                 ARTICLE THREE

                            MISCELLANEOUS PROVISIONS

          OLIN CORPORATION, a corporation duly organized and existing under the
laws of the State of Virginia (herein called the "Company" which term includes
any successor corporation under the Indenture referred to on the reverse
hereof), for value received, hereby promises to pay to

          U.S. DOLLARS on the Maturity Date specified above, and to pay
interest thereon at a rate per annum equal to the Initial Interest Rate (   %)
until the first Interest Reset Date (             ) following the Original
Issue Date (            ) and thereafter at a rate determined in accordance 
with the provisions on the reverse hereof under the heading "Determination of 
Commercial Paper Rate", "Determination of Prime Rate", "Determination of LIBOR",

monthly, quarterly, semi-annually or annually as specified in the Prospectus
Supplement or in the applicable Pricing Supplement, commencing with the first
Interest Payment Date specified above next succeeding the Original Issue Date
and thereafter on the Interest Payment Dates as specified therein, and on the
Maturity Date.  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, next preceding such Interest Payment Date; provided,
however, that interest payable at Maturity shall be payable to the Person to
whom principal shall be payable.  If any Interest Payment Date would fall on a
day that is not a Business Day, such Interest Payment Date will be the
following day that is a Business Day, except that, if the rate of interest on
the Security shall be determined in accordance with the provisions of the
heading "Determination of LIBOR" below (a "LIBOR Note"), and if such Business
Day is in the next succeeding calendar month, such Interest Payment Date shall
be the immediately preceding Business Day. If the Maturity Date or any earlier
Redemption Date of a Security would fall 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 for
the period from and after such Maturity Date or Redemption Date, as the case
may be.

          Payment of the principal, premium, if any, and interest on this
Security will be made at the principal corporate trust office of the Trustee in
the Borough of Manhattan, The City of New York, or such other office or agency
of the Company as may be designated by it for such purpose in the Borough of
Manhattan, The City of New York (the "Paying Agent"), in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that at the option of
the Company payment of interest (except at Maturity) may be made by United
States dollar check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register.  Payment of the principal,
premium, if any, and interest on

this Security due at Maturity will be made in immediately available funds upon
surrender of this Security to the Paying Agent; provided that this Security is
presented to the Paying Agent in time for the Paying Agent to make such payment
in accordance with its normal procedures.  "Maturity" shall mean the date on
which the principal of this Security or an installment of principal becomes
due, whether on the Maturity Date specified in the Prospectus Supplement, upon
redemption or otherwise.

PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

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

                                (Floating Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of June 15, 1992, as supplemented as
of March 18, 1994 (herein called the "Indenture"), between the Company
and Chemical Bank, as Trustee (herein called the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered.
This Security is one of the series designated on the face hereof.

          This Security may not be redeemed prior to the Redemption Date set
forth in the applicable Pricing Supplement.  If no Redemption Date is so set
forth, this Security is not redeemable prior to the Maturity Date.  On or after
the Redemption Date set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60 days prior to the date fixed for redemption,
all as provided in the Indenture.

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

                                                                               6

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable Pricing Supplement.

          Commencing with the first Interest Reset Date specified in the
Prospectus Supplement or in the applicable Pricing Supplement following the
Original Issue Date, the rate at which interest on this Security is payable
shall be adjusted daily, weekly, monthly, quarterly, semi-annually or annually
as shown in the Prospectus Supplement or in the applicable Pricing Supplement
under "Interest Rate Reset Period"; provided, however, that the interest rate
in effect hereon for the 10 days immediately prior to the Maturity hereof,
shall be that in effect on the 10th day preceding the Maturity hereof.  Each
such adjusted rate shall be applicable on and after the Interest Reset Date to
which it relates, to but not including the next succeeding Interest Reset Date
or until Maturity, as the case may be.  If any Interest Reset Date specified on
the face hereof would otherwise be a day that is not a Business Day, such
Interest Reset Date shall be postponed to the next succeeding day that is a
Business Day, except that in the case of LIBOR Notes if such Business Day
is in the next succeeding calendar month, such Interest Reset Date shall be the
immediately preceding Business Day.  "Business Day" shall mean any day,
other than a Saturday or Sunday, that is neither a legal holiday nor a day on
which banking institutions are generally authorized or required by law or
regulation to close in The City of New York and (i) in respect of LIBOR Notes
in the City of London and which is a London Banking Day, (ii) with respect to
Securities denominated or payable in a Specified Currency other than European
Currency Units as defined and revised from time to time by the Council of the
European Communities ("ECU"), in the financial center of the country issuing
the Specified Currency and (iii) with respect to Securities denominated or
payable in ECUs, in the financial center of each country that issues a
component currency of the ECU, and that is an ECU settlement day.  "London
Banking Day" means any day on which dealings in deposits in United States
dollars are transacted in the London interbank market.  Subject to applicable
provisions of law and except as specified herein, on each Interest Reset Date,
the rate of interest on this Security shall be the rate determined in
accordance with the provisions of the applicable heading below.

          The interest rate on this Security will in no event be higher than the
maximum rate permitted by New York

                                                                               7

law as the same may be modified by United States law of general applicability.

          DETERMINATION OF COMMERCIAL PAPER RATE.  The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Commercial Paper Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Commercial Paper Rate" means, with respect
to each Interest Determination Date specified on the face hereof, the Money
Market Yield (calculated as described below) of the rate on such date for
commercial paper having the Index Maturity specified on the face hereof as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "Commercial Paper".  In the event that such
rate is not published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
will be the Money Market Yield of the rate on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof 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 the Calculation Date pertaining to such Interest
Determination Date such rate is not yet available in either H.15(519) or the
Composite Quotations, then the Commercial Paper Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
Money Market Yield of the arithmetic mean (rounded to the next higher one
hundred thousandth of a percentage point) of the offered rates of three leading
dealers of commercial paper in The City of New York selected by the Calculation
Agent as of 11:00 A.M., New York City time, on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof
placed for an industrial issuer whose bond rating is "AA", or the equivalent,
from a nationally recognized rating agency; provided, however, that if the
dealers selected as aforesaid by the Calculation Agent are not quoting as
mentioned in this sentence, the Commercial Paper Rate will be the Commercial
Paper Rate in effect on such Interest Determination Date.

          "Money Market Yield" means a yield (expressed as  a percentage
rounded to the next higher one hundred thou-

                                                                               8

sandth of a percentage point) calculated in accordance with the following
formula:

                   Money Market Yield =     D  x  360    x  100
                                          --------------   
                                          360 - (D x M)

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.

          DETERMINATION OF PRIME RATE.  The interest rate payable with respect
to this Security shall be calculated by the Calculation Agent with reference to
the Prime Rate and the Spread or Spread Multiplier, if any, specified on the
face hereof.  "Prime Rate" means, with respect to each Interest Determination
Date specified on the face hereof, the rate published in H.15(519) for such
date opposite the caption "Bank Prime Loan."  If such rate is not yet published
by 3:00 P.M., New York City time, on the Calculation Date pertaining to such
Interest Determination Date, the Prime Rate for such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the rates of interest publicly announced
by each bank named on the Reuters Screen NYMF Page (as defined below) as such
bank's prime rate or base lending rate as in effect for such Interest
Determination Date as quoted on the Reuters Screen NYMF Page on such Interest
Determination Date, or, if fewer than four such rates appear on the Reuters
Screen NYMF Page for such Interest Determination Date, the rate shall be the
arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) of the prime rates quoted on the basis of the actual number
of days in the year divided by 360 as of the close of business on such Interest
Determination Date by at least two of the three major money center banks in The
City of New York selected by the Calculation Agent from which quotations are
requested.  If fewer than two quotations are provided, the Prime Rate shall be
calculated by the Calculation Agent and shall be determined as the arithmetic
mean (rounded to the next higher one hundred thousandth of a percentage point)
on the basis of the prime rates in The City of New York by the appropriate
number of substitute banks or trust companies organized and doing business
under the laws of the United States, or any State thereof, in each case having
total equity capital of at least U.S. $500 million and being subject to
supervision or examination by Federal or

                                                                               9

State authority, selected by the Calculation Agent to quote such rate or rates.

     "Reuters Screen NYMF Page" means the display designated as Page "NYMF" on
the Reuters Monitor Money Rates Services (or such other page as may replace the
NYMF Page on that service for the purpose of displaying prime rates or base
lending rates of major United States banks).

     If in any month or two consecutive months the Prime Rate is not published
in H.15(519) and the banks or trust companies selected as aforesaid are not
quoting as mentioned above, the "Prime Rate" for such Interest Reset Period
will be the same as the Prime Rate for the immediately preceding Interest Reset
Period (or, if there was no such Interest Reset Period, the rate of interest
payable on the Security for which the Prime Rate is being determined shall be
the Initial Interest Rate).  If this failure continues over three or more
consecutive months, the Prime Rate for each succeeding Interest Determination
Date until the maturity or redemption or repayment of such Securities or, if
earlier, until this failure ceases, shall be LIBOR determined as if such
Securities were LIBOR Notes, and the Spread, if any, shall be the number of
basis points specified in the applicable Pricing Supplement as the "Alternative
Rate Event Spread".

          DETERMINATION OF LIBOR.  The interest rate payable with respect to
this Security shall be calculated with reference to LIBOR and the Spread or
Spread Multiplier, if any, specified on the face hereof.  "LIBOR" will be
determined with respect to each Interest Determination Date specified on the
face hereof by the Calculation Agent in accordance with the following
provisions:  On each Interest Determination Date relating to a LIBOR Note,
LIBOR will be (a) where the applicable Pricing Supplement specifies
LIBOR-Telerate (as defined below) as the method for determining LIBOR, the rate
for deposits in U.S. dollars having the Index Maturity specified on the face
hereof which appears on the Telerate Page 3750 (as defined below) as of 11:00
A.M., London time, on such Interest Determination Date ("LIBOR- Telerate") or
(b) where the applicable Pricing Supplement specifies LIBOR-Reuters (as defined
below) as the method of determining LIBOR, the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the offered rates
for deposits in U.S. dollars having the Index Maturity specified on the face
hereof which appear on the Reuters Screen LIBO Page (as defined below) as of
11:00 A.M., London
<PAGE>   10
                                                                              10

time, on such Interest Determination Date, provided that at least two such
offered rates appear on the Reuters Screen LIBO Page ("LIBOR-Reuters");
provided, however, that if the method for determining LIBOR with respect to any
LIBOR Note is not specified therein or in the applicable Pricing Supplement,
"LIBOR" means LIBOR-Telerate.

          If on any Interest Determination Date, (x) in any case where LIBOR-
Telerate applies, the rate for deposits in U.S. dollars having the applicable
Index Maturity does not appear on the Telerate Page 3750 as specified in (a)
above, or (y) in any case where LIBOR-Reuters applies, fewer than two offered
rates for deposits in U.S. dollars having the applicable Index Maturity appear
on the Reuters Screen LIBO Page as specified in (b) above, LIBOR 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 such Interest
Determination Date to prime banks in the London interbank market having the
Index Maturity specified on the face hereof and in a principal amount equal to
an amount that is representative for a single transaction in such market at
such time.  The Calculation Agent will request the principal London office of
each of such banks to provide a quotation of its rate.  If at least two such
quotations are provided, the rate in respect of such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the quotations.  If fewer than two
quotations are provided, LIBOR in respect of such Interest Determination Date
will be the arithmetic mean (rounded to the next higher one hundred thousandth
of a percentage point) 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 such Interest Determination Date for loans in U.S. dollars
to leading European banks, having the Index Maturity specified on the fact
hereof and in a principal amount equal to an amount that is representative for
a single transaction in such market at such time; provided, however, that if
the banks selected as aforesaid by the Calculation Agent are not quoting as
described in this sentence, LIBOR for such Interest Reset Period will be the
same as LIBOR for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the LIBOR
Notes for which LIBOR is being determined shall be the Initial Interest Rate).

     "Telerate Page 3750" means the display page designated as page 3750 on the
Dow Jones Telerate Service (or such other page as may replace page 3750 on that
service for the purpose of displaying London interbank offered rates).

     "Reuters Screen LIBO Page" means the display page designated as page
"LIBO" on the Reuters Monitor Money Rates Service (or such other page as may
replace the LIBO page on that service for the purpose of displaying London
interbank offered rates).

          DETERMINATION OF TREASURY RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Treasury Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate for the
auction held on such date of direct obligations of the United States ("Treasury
bills") having the Index Maturity specified on the face hereof 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 Interest
Determination Date, the Treasury Rate will be the auction average rate,
expressed as a Bond Equivalent Yield (calculated as described below), for such
auction as otherwise announced by the United States Department of the Treasury.
If the results of the auction of Treasury bills having the Index Maturity
specified on the face hereof are not published or announced as provided above
by 3:00 P.M., New York City time, on such Calculation Date, or if no such
auction is held on such Interest Determination Date, then the Treasury Rate
shall be calculated by the Calculation Agent and shall be a yield to maturity,
expressed as a Bond Equivalent Yield, of the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the secondary
market bid rates as of approximately 3:30 P.M., New York City time, on such
Interest Determination Date, of three leading primary United States government
securities dealers 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 with
respect to such Interest Determination Date will be the Treasury Rate in effect
on such Interest Determination Date.

          "Bond Equivalent Yield" shall be a yield (expressed as a percentage
rounded to the next higher one-hundred thousandth of a percentage point)
calculated in accordance with the following formula:

                  Bond Equivalent Yield =    D  x  N    x 100

where "D" refers to the per annum rate for Treasury bills, quoted on a bank
discount basis and expressed as a decimal; "N" refers to the actual number of
days in the year for which interest is being calculated; and "M" refers to the
actual number of days in the interest period for which interest is being
calculated.

          DETERMINATION OF FEDERAL FUNDS RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Federal Funds Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Federal Funds Rate" means, with respect to
each Interest Determination Date specified on the face hereof, the rate on such
date for Federal Funds as published in H.15(519) under the heading "Federal
Funds (Effective)" or, if not so published by 3:00 P.M., New York City time, on
the Calculation Date pertaining to such Interest Determination Date, then the
Federal Funds Rate for such Interest Determination Date will be the rate on
such Interest Determination Date as published in the Composite Quotations under
the heading "Federal Funds/ Effective Rate".  If such rate is not yet published
in either H.15 (519) or Composite Quotations by 3:00 P.M., New York City time,
on the Calculation Date pertaining to such Interest Determination Date, then
the Federal Funds Rate for such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the rates for the last
transaction in overnight Federal Funds, as of 11:00 A.M., New York City time,
on such Interest Determination Date, arranged by three leading brokers of
Federal Funds transactions in The City of New York selected by the Calculation
Agent; provided, however, that if the brokers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Federal
Funds Rate in effect for the applicable period will be the same as the Federal
Funds Rate for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the
Securities for which such
<PAGE>   13
                                                                              13

Federal Funds Rate is being determined shall be the Initial Interest Rate).

          DETERMINATION OF CD RATE.  The interest rate payable with respect to
this Security shall be calculated by the Calculation Agent with reference to
the CD Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof.  "CD Rate" means, with respect to each Interest Determination Date, the
rate on such date for negotiable certificates of deposit having the Index
Maturity specified on the face hereof as published in H.15(519) under the
heading "CDs (Secondary Market)" or, if not so published by 3:00 P.M., New York
City time, on the Calculation Date pertaining to such Interest Determination
Date, the CD Rate will be the rate on such Interest Determination Date for
negotiable certificates of deposit of the Index Maturity specified on the face
hereof as published in the Composite Quotations under the heading "Certificates
of Deposit".  If such rate is not yet published in either H.15(519) or the
Composite Quotations by 3:00 P.M., New York City time, on such Calculation
Date, then the CD Rate on such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the secondary market
offered rates as of 10:00 A.M., New York City time, on such Interest
Determination Date, for certificates of deposit in the denomination of
$5,000,000 with a remaining maturity closest to the Index Maturity specified on
the fact hereof of three leading nonbank dealers in 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
center banks of the highest credit standing in the market for negotiable
certificates of deposit; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as set forth above, the CD
Rate in effect for the applicable period will be the same as the CD Rate for
the immediately preceding Interest Reset Period (or, if there was no such
Interest Reset Period, the rate of interest payable on the Securities for which
such CD Rate is being determined shall be the Initial Interest Rate).

          Notwithstanding the foregoing, the interest rate hereon shall not be
greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, shown on the face hereof.  The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing
on or before each Calculation Date and shall promptly thereafter notify the
Company and the Trustee of
<PAGE>   14
                                                                              14

such interest rate.  Any such calculation by the Calculation Agent shall be
conclusive and binding on the Company, the Trustee and the Holder of this
Security, absent manifest error.

          The Calculation Agent will, upon the request of the Holder of this
Security, provide to such Holder the interest rate hereon then in effect and,
if determined, the interest rate which will become effective as of the next
Interest Reset Date.

          If any Interest Payment Date specified on the face hereof would
otherwise be a day that is not a Business Day, the Interest Payment Date shall
be postponed to the next day that is a Business Day, except in the case of
LIBOR Notes, if such London Banking Day is in the next succeeding calendar
month, such Interest Payment Date shall be the immediately preceding London
Banking Day.

          The Interest Determination Date pertaining to an Interest Reset Date
if the rate of interest on the Security shall be determined in accordance with
the provisions of the headings "Determination of Commercial Paper Rate",
"Determination of Prime Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate" above will be the second Business Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date on a LIBOR Note will be the second London Banking Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date if the rate of interest on the Security shall be determined in
accordance with the provisions of the heading "Determination of Treasury Rate"
above (the "Treasury Interest Determination Date") will be the day of the week
in which such Interest Reset Date falls on which Treasury bills would normally
be auctioned.  Treasury bills are usually sold at auction on the 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, as a result of a legal holiday, an auction is so held on
the preceding Friday, such Friday will be the Treasury Interest Determination
Date pertaining to the Interest Reset Date occurring in the next succeeding
week.  If an auction date shall fall on any Interest Reset Date for a Treasury
Rate Note, then such Interest Reset Date shall instead be the first Business
Day immediately following such auction date.
<PAGE>   15
                                                                              15

          The Calculation Date, if applicable, pertaining to any Interest
Determination Date will be the earlier of the tenth calendar day after such
Interest Determination Date, or the next succeeding Record Date after such
Interest Determination Date or, if either such day is not a Business Day, the
next succeeding Business Day.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date; provided, however, that if the
interest rate with respect to this Security is reset daily or weekly, interest
payable on any Interest Payment Date, other than interest payable on any date
on which principal hereof is payable, will include interest accrued to and
including the Record Date immediately preceding such Interest Payment Date, or
from and including the date of issue, if no interest has been paid with respect
to such Note, to and including the next preceding Regular Record Date.  Accrued
interest hereon from and including the Original Issue Date, or from but
excluding the last date to which interest hereon has been paid or duly provided
for, as the case may be, will be an amount calculated by multiplying the face
amount hereof by an accrued interest factor.  Such accrued interest factor will
be computed by adding the interest factor calculated for each day from and
including the Original Issue Date, or from but excluding the last date to which
interest shall have been paid or duly provided for, as the case may be, to and
including the date for which accrued interest is being calculated.  The
interest factor (expressed as a decimal rounded upwards, if necessary, to the
next higher one-hundred thousandth of a percentage point) for each such day
will be computed by dividing the interest rate (expressed as a decimal rounded
upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point) applicable to such day by 360, in the case of the Commercial
Paper Rate, LIBOR, the Federal Funds Rate, the Prime Rate or the CD Rate, or by
the actual number of days in the year, in the case of the Treasury Rate.  The
interest factor for Floating Rate Notes for which two or more interest rate
formulae are applicable will be calculated in the same manner as if only the
lowest, highest or average of, as the case may be, such interest rate formulae
applied.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or
<PAGE>   16

                                                                              16

other encumbrance upon any real or personal property located in the continental
United States of America without effectively providing that the Securities will
be secured equally and ratably with (or, at the option of the Company, prior
to) such indebtedness so long as such indebtedness shall be so secured or (ii)
enter into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, U.S. Government Obligations
(as defined in the Indenture) which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money or a
combination of money and U.S. Government Obligations in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on,
the Securities on the dates such payments are in accordance with the terms of
the Securities.

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

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66 2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this
<PAGE>   17
                                                                              17

Security and of any Security issued upon the registration or transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal, premium, if
any, or interest on this Security on or after the respective due dates
expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this Series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount will be issued to the designated transferee or transferees.
<PAGE>   18
                                                                              18

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

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

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

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

                                  (Fixed Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of June 15, 1992, as supplemented as
of , 1994 (herein called the "Indenture"), between the Company and Chemical
Bank, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
securities are, and are to be, authenticated and delivered.  This Security is
one of the series designated on the face hereof.

          This Security may not be redeemed prior to the Redemption Date set
forth on the face hereof.  If no Redemption Date is so set forth, this Security
is not redeemable prior to the Maturity Date.  On or after the Redemption Date
set forth on the face hereof, this Security is redeemable in whole or in part
in increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60  days prior to the date fixed for redemption,
all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable pricing supplement.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States of
America without effectively providing that the Securities will be secured
equally and ratably with (or, at the option of the Company, prior to) such
indebtedness so long as such indebtedness shall be so secured or (ii) enter
into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee money or U.S. Government
Obligations (as defined in the Indenture), which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money or a combination of money and U.S. Government Obligations in an
amount sufficient to pay all the principal, premium, if any, and interest on,
the Securities on the dates such payments are due in accordance with the terms
of the Securities.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date.  Interest payments for this Security
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months.

          The interest rate on this Security will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general applicability.

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

                                                                               6

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66-2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal, premium, if
any, or interest on this Security on or after the respective due dates
expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

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

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

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

          OLIN CORPORATION, a corporation duly organized and existing under the
laws of the State of Virginia (herein called the "Company" which term includes
any successor corporation under the Indenture referred to on the reverse
hereof), for value received, hereby promises to pay to

           , or registered assigns, the principal sum of

U.S. DOLLARS on the Maturity Date specified above, and to pay interest thereon
at a rate per annum equal to the Initial Interest Rate (   %) until the first
Interest Reset Date (             ) following the Original Issue Date (
) and thereafter at a rate determined in accordance with the provisions on the
reverse hereof under the heading "Determination of Commercial Paper Rate",
"Determination of Prime Rate", "Determination of LIBOR", "Determination of
Treasury Rate", "Determination of Federal Funds Rate" or "Determination of CD
Rate", depending upon whether the Interest Rate Basis specified above is the
Commercial Paper Rate, Prime Rate, LIBOR, Treasury Rate, Federal Funds Rate or
CD Rate, which rate may be adjusted by adding or subtracting the Spread or
multiplying by the Spread Multiplier (as such terms are defined below)
depending on whether a Spread or Spread Multiplier is designated above, until
the principal hereof is paid or duly made available for payment.  In addition,
a Floating Rate Note may bear interest at the lowest or highest or average of

monthly, quarterly, semi-annually or annually as specified in the Prospectus
Supplement or in the applicable Pricing Supplement, commencing with the first
Interest Payment Date specified above next succeeding the Original Issue Date
and thereafter on the Interest Payment Dates as specified therein, and on the
Maturity Date.  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, next preceding such Interest Payment Date; provided,
however, that interest payable at Maturity shall be payable to the Person to
whom principal shall be payable.  If any Interest Payment Date would fall on a
day that is not a Business Day, such Interest Payment Date will be the
following day that is a Business Day, except that, if the rate of interest on
the Security shall be determined in accordance with the provisions of the
heading "Determination of LIBOR" below (a "LIBOR Note"), and if such Business
Day is in the next succeeding calendar month, such Interest Payment Date shall
be the immediately preceding Business Day. If the Maturity Date or any earlier
Redemption Date of a Security would fall 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 for
the period from and after such Maturity Date or Redemption Date, as the case
may be.

          Payment of the principal, premium, if any, and interest on this
Security will be made to the Depositary or its nominee as Holder thereof, in
accordance with arrangements then in effect between the Trustee and the
Despositary, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest
(except at Maturity) may be made by United States dollar check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register (which, in the case of Book-Entry Notes, will be a nominee of
the Depositary).  Payment of the principal, premium, if any, and interest on
this Security due at Maturity will be made in

immediately available funds upon surrender of this Security; provided that this
Security is presented in time for the paying agent to make such payment in
accordance with its normal procedures.  "Maturity" shall mean the date on which
the principal of this Security or an installment of principal becomes due,
whether on the Maturity Date specified in the Prospectus Supplement, upon
redemption or otherwise.

PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH IN FULL AT THIS PLACE.

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

                                (Floating Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of June 15, 1992, as supplemented as
of March 18, 1994 (herein called the "Indenture"), between the Company
and Chemical Bank, as Trustee (herein called the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered.
This Security is one of the series designated on the face hereof.

          This Security may not be redeemed prior to the Redemption Date set
forth in the applicable Pricing Supplement.  If no Redemption Date is so set
forth, this Security is not redeemable prior to the Maturity Date.  On or after
the Redemption Date set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60 days prior to the date fixed for redemption,
all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable Pricing Supplement.

          Commencing with the first Interest Reset Date specified in the
Prospectus Supplement or in the applicable Pricing Supplement following the
Original Issue Date, the rate at which interest on this Security is payable
shall be adjusted daily, weekly, monthly, quarterly, semi-annually or annually
as shown in the Prospectus Supplement or in the applicable Pricing Supplement
under "Interest Rate Reset Period"; provided, however, that the interest rate
in effect hereon for the 10 days immediately prior to the Maturity hereof,
shall be that in effect on the 10th day preceding the Maturity hereof.  Each
such adjusted rate shall be applicable on and after the Interest Reset Date to
which it relates, to but not including the next succeeding Interest Reset Date
or until Maturity, as the case may be.  If any Interest Reset Date specified on
the face hereof would otherwise be a day that is not a Business Day, such
Interest Reset Date shall be postponed to the next succeeding day that is a
Business Day, except that in the case of LIBOR Notes if such Business Day
is in the next succeeding calendar month, such Interest Reset Date shall be the
immediately preceding Business Day.  "Business Day" shall mean any day,
other than a Saturday or Sunday, that is neither a legal holiday nor a day on
which banking institutions are generally authorized or required by law or
regulation to close in The City of New York and (i) in respect of LIBOR Notes
in the City of London and which is a London Banking Day, (ii) with respect to
Securities denominated or payable in a Specified Currency other than European
Currency Units as defined and revised from time to time by the Council of the
European Communities ("ECU"), in the financial center of the country issuing
the Specified Currency and (iii) with respect to Securities denominated or
payable in ECUs, in the financial center of each country that issues a
component currency of the ECU, and that is an ECU settlement day.  "London
Banking Day" means any day on which dealings in deposits in United States
dollars are transacted in the London interbank market.  Subject to applicable
provisions of law and except as specified herein, on each Interest Reset Date,
the rate of interest on this Security shall be the rate determined in
accordance with the provisions of the applicable heading below.

The interest rate on this Security will in no event be higher than the
maximum rate permitted by New York

                                                                               7

law as the same may be modified by United States law of general applicability.

          DETERMINATION OF COMMERCIAL PAPER RATE.  The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Commercial Paper Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Commercial Paper Rate" means, with respect
to each Interest Determination Date specified on the face hereof, the Money
Market Yield (calculated as described below) of the rate on such date for
commercial paper having the Index Maturity specified on the face hereof as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "Commercial Paper".  In the event that such
rate is not published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
will be the Money Market Yield of the rate on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof 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 the Calculation Date pertaining to such Interest
Determination Date such rate is not yet available in either H.15(519) or the
Composite Quotations, then the Commercial Paper Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
Money Market Yield of the arithmetic mean (rounded to the next higher one
hundred thousandth of a percentage point) of the offered rates of three leading
dealers of commercial paper in The City of New York selected by the Calculation
Agent as of 11:00 A.M., New York City time, on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof
placed for an industrial issuer whose bond rating is "AA", or the equivalent,
from a nationally recognized rating agency; provided, however, that if the
dealers selected as aforesaid by the Calculation Agent are not quoting as
mentioned in this sentence, the Commercial Paper Rate will be the Commercial
Paper Rate in effect on such Interest Determination Date.

          "Money Market Yield" means a yield (expressed as  a percentage
rounded to the next higher one hundred thou-
<PAGE>   8
                                                                               8

sandth of a percentage point) calculated in accordance with the following
formula:

               Money Market Yield =     D  x  360    x  100
                                      -------------
                                      360 - (D x M)

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.

          DETERMINATION OF PRIME RATE.  The interest rate payable with respect
to this Security shall be calculated by the Calculation Agent with reference to
the Prime Rate and the Spread or Spread Multiplier, if any, specified on the
face hereof.  "Prime Rate" means, with respect to each Interest Determination
Date specified on the face hereof, the rate published in H.15(519) for such
date opposite the caption "Bank Prime Loan."  If such rate is not yet published
by 3:00 P.M., New York City time, on the Calculation Date pertaining to such
Interest Determination Date, the Prime Rate for such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the rates of interest publicly announced
by each bank named on the Reuters Screen NYMF Page (as defined below) as such
bank's prime rate or base lending rate as in effect for such Interest
Determination Date as quoted on the Reuters Screen NYMF Page on such Interest
Determination Date, or, if fewer than four such rates appear on the Reuters
Screen NYMF Page for such Interest Determination Date, the rate shall be the
arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) of the prime rates quoted on the basis of the actual number
of days in the year divided by 360 as of the close of business on such Interest
Determination Date by at least two of the three major money center banks in The
City of New York selected by the Calculation Agent from which quotations are
requested.  If fewer than two quotations are provided, the Prime Rate shall be
calculated by the Calculation Agent and shall be determined as the arithmetic
mean (rounded to the next higher one hundred thousandth of a percentage point)
on the basis of the prime rates in The City of New York by the appropriate
number of substitute banks or trust companies organized and doing business

total equity capital of at least U.S. $500 million and being subject to
supervision or examination by Federal or

State authority, selected by the Calculation Agent to quote such rate or rates.

     "Reuters Screen NYMF Page" means the display designated as Page "NYMF" on
the Reuters Monitor Money Rates Services (or such other page as may replace the
NYMF Page on that service for the purpose of displaying prime rates or base
lending rates of major United States banks).

     If in any month or two consecutive months the Prime Rate is not published
in H.15(519) and the banks or trust companies selected as aforesaid are not
quoting as mentioned above, the "Prime Rate" for such Interest Reset Period
will be the same as the Prime Rate for the immediately preceding Interest Reset
Period (or, if there was no such Interest Reset Period, the rate of interest
payable on the Security for which the Prime Rate is being determined shall be
the Initial Interest Rate).  If this failure continues over three or more
consecutive months, the Prime Rate for each succeeding Interest Determination
Date until the maturity or redemption or repayment of such Securities or, if
earlier, until this failure ceases, shall be LIBOR determined as if such
Securities were LIBOR Notes, and the Spread, if any, shall be the number of
basis points specified in the applicable Pricing Supplement as the "Alternative
Rate Event Spread".

          DETERMINATION OF LIBOR.  The interest rate payable with respect to
this Security shall be calculated with reference to LIBOR and the Spread or
Spread Multiplier, if any, specified on the face hereof.  "LIBOR" will be
determined with respect to each Interest Determination Date specified on the
face hereof by the Calculation Agent in accordance with the following
provisions:  On each Interest Determination Date relating to a LIBOR Note,
LIBOR will be (a) where the applicable Pricing Supplement specifies
LIBOR-Telerate (as defined below) as the method for determining LIBOR, the rate
for deposits in U.S. dollars having the Index Maturity specified on the face
hereof which appears on the Telerate Page 3750 (as defined below) as of 11:00
A.M., London time, on such Interest Determination Date ("LIBOR- Telerate") or
(b) where the applicable Pricing Supplement specifies LIBOR-Reuters (as defined
below) as the method of determining LIBOR, the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the offered rates
for deposits in U.S. dollars having the Index Maturity specified on the face
hereof which appear on the Reuters Screen LIBO Page (as defined below) as of
11:00 A.M., London
<PAGE>   10
                                                                              10

time, on such Interest Determination Date, provided that at least two such
offered rates appear on the Reuters Screen LIBO Page ("LIBOR-Reuters");
provided, however, that if the method for determining LIBOR with respect to any
LIBOR Note is not specified therein or in the applicable Pricing Supplement,
"LIBOR" means LIBOR- Telerate.

          If on any Interest Determination Date, (x) in any case where LIBOR-
Telerate applies, the rate for deposits in U.S. dollars having the applicable
Index Maturity does not appear on the Telerate Page 3750 as specified in (a)
above, or (y) in any case where LIBOR-Reuters applies, fewer than two offered
rates for deposits in U.S. dollars having the applicable Index Maturity appear
on the Reuters Screen LIBO Page as specified in (b) above, LIBOR 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 such Interest
Determination Date to prime banks in the London interbank market having the
Index Maturity specified on the face hereof and in a principal amount equal to
an amount that is representative for a single transaction in such market at
such time.  The Calculation Agent will request the principal London office of
each of such banks to provide a quotation of its rate.  If at least two such
quotations are provided, the rate in respect of such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the quotations.  If fewer than two
quotations are provided, LIBOR in respect of such Interest Determination Date
will be the arithmetic mean (rounded to the next higher one hundred thousandth
of a percentage point) 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 such Interest Determination Date for loans in U.S. dollars
to leading European banks, having the Index Maturity specified on the fact
hereof and in a principal amount equal to an amount that is representative for
a single transaction in such market at such time; provided, however, that if
the banks selected as aforesaid by the Calculation Agent are not quoting as
described in this sentence, LIBOR for such Interest Reset Period will be the
same as LIBOR for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the LIBOR
Notes for which LIBOR is being determined shall be the Initial Interest Rate).

     "Telerate Page 3750" means the display page designated as page 3750 on the
Dow Jones Telerate Service (or such other page as may replace page 3750 on that
service for the purpose of displaying London interbank offered rates).

     "Reuters Screen LIBO Page" means the display page designated as page
"LIBO" on the Reuters Monitor Money Rates Service (or such other page as may
replace the LIBO page on that service for the purpose of displaying London
interbank offered rates).

          DETERMINATION OF TREASURY RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Treasury Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate for the
auction held on such date of direct obligations of the United States ("Treasury
bills") having the Index Maturity specified on the face hereof 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 Interest
Determination Date, the Treasury Rate will be the auction average rate,
expressed as a Bond Equivalent Yield (calculated as described below), for such
auction as otherwise announced by the United States Department of the Treasury.
If the results of the auction of Treasury bills having the Index Maturity
specified on the face hereof are not published or announced as provided above
by 3:00 P.M., New York City time, on such Calculation Date, or if no such
auction is held on such Interest Determination Date, then the Treasury Rate
shall be calculated by the Calculation Agent and shall be a yield to maturity,
expressed as a Bond Equivalent Yield, of the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the secondary
market bid rates as of approximately 3:30 P.M., New York City time, on such
Interest Determination Date, of three leading primary United States government
securities dealers 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 with
respect to such Interest Determination Date will be the Treasury Rate in effect
on such Interest Determination Date.

          "Bond Equivalent Yield" shall be a yield (expressed as a percentage
rounded to the next higher one-hundred thousandth of a percentage point)
calculated in accordance with the following formula:

               Bond Equivalent Yield =    D  x  N    x 100
                                        -------------
                                        360 - (D x M)

where "D" refers to the per annum rate for Treasury bills, quoted on a bank
discount basis and expressed as a decimal; "N" refers to the actual number of
days in the year for which interest is being calculated; and "M" refers to the
actual number of days in the interest period for which interest is being
calculated.

          DETERMINATION OF FEDERAL FUNDS RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Federal Funds Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Federal Funds Rate" means, with respect to
each Interest Determination Date specified on the face hereof, the rate on such
date for Federal Funds as published in H.15(519) under the heading "Federal
Funds (Effective)" or, if not so published by 3:00 P.M., New York City time, on
the Calculation Date pertaining to such Interest Determination Date, then the
Federal Funds Rate for such Interest Determination Date will be the rate on
such Interest Determination Date as published in the Composite Quotations under
the heading "Federal Funds/ Effective Rate".  If such rate is not yet published
in either H.15 (519) or Composite Quotations by 3:00 P.M., New York City time,
on the Calculation Date pertaining to such Interest Determination Date, then
the Federal Funds Rate for such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the rates for the last
transaction in overnight Federal Funds, as of 11:00 A.M., New York City time,
on such Interest Determination Date, arranged by three leading brokers of
Federal Funds transactions in The City of New York selected by the Calculation
Agent; provided, however, that if the brokers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Federal
Funds Rate in effect for the applicable period will be the same as the Federal
Funds Rate for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the
Securities for which such
<PAGE>   13
                                                                              13

Federal Funds Rate is being determined shall be the Initial Interest Rate).
          
          DETERMINATION OF CD RATE.  The interest rate payable with respect to
this Security shall be calculated by the Calculation Agent with reference to 
the CD Rate and the Spread or Spread Multiplier, if any, specified on the face 
hereof. "CD Rate" means, with respect to each Interest Determination Date, the 
rate on such date for negotiable certificates of deposit having the Index 
Maturity specified on the face hereof as published in H.15(519) under the 
heading "CDs (Secondary Market)" or, if not so published by 3:00 P.M., New York 
City time, on the Calculation Date pertaining to such Interest Determination 
Date, the CD Rate will be the rate on such Interest Determination Date for 
negotiable certificates of deposit of the Index Maturity specified on the face 
hereof as published in the Composite Quotations under the heading "Certificates 
of Deposit".  If such rate is not yet published in either H.15(519) or the
Composite Quotations by 3:00 P.M., New York City time, on such Calculation
Date, then the CD Rate on such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the secondary market
offered rates as of 10:00 A.M., New York City time, on such Interest
Determination Date, for certificates of deposit in the denomination of
$5,000,000 with a remaining maturity closest to the Index Maturity specified on
the fact hereof of three leading nonbank dealers in 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
center banks of the highest credit standing in the market for negotiable
certificates of deposit; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as set forth above, the CD
Rate in effect for the applicable period will be the same as the CD Rate for
the immediately preceding Interest Reset Period (or, if there was no such
Interest Reset Period, the rate of interest payable on the Securities for which
such CD Rate is being determined shall be the Initial Interest Rate).

          Notwithstanding the foregoing, the interest rate hereon shall not be
greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, shown on the face hereof.  The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing
on or before each Calculation Date and shall promptly thereafter notify the
Company and the Trustee of
<PAGE>   14
                                                                              14

such interest rate.  Any such calculation by the Calculation Agent shall be
conclusive and binding on the Company, the Trustee and the Holder of this
Security, absent manifest error.

          The Calculation Agent will, upon the request of the Holder of this
Security, provide to such Holder the interest rate hereon then in effect and,
if determined, the interest rate which will become effective as of the next
Interest Reset Date.

          If any Interest Payment Date specified on the face hereof would
otherwise be a day that is not a Business Day, the Interest Payment Date shall
be postponed to the next day that is a Business Day, except in the case of
LIBOR Notes, if such London Banking Day is in the next succeeding calendar
month, such Interest Payment Date shall be the immediately preceding London
Banking Day.

          The Interest Determination Date pertaining to an Interest Reset Date
if the rate of interest on the Security shall be determined in accordance with
the provisions of the headings "Determination of Commercial Paper Rate",
"Determination of Prime Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate" above will be the second Business Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date on a LIBOR Note will be the second London Banking Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date if the rate of interest on the Security shall be determined in
accordance with the provisions of the heading "Determination of Treasury Rate"
above (the "Treasury Interest Determination Date") will be the day of the week
in which such Interest Reset Date falls on which Treasury bills would normally
be auctioned.  Treasury bills are usually sold at auction on the 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, as a result of a legal holiday, an auction is so held on
the preceding Friday, such Friday will be the Treasury Interest Determination
Date pertaining to the Interest Reset Date occurring in the next succeeding
week.  If an auction date shall fall on any Interest Reset Date for a Treasury
Rate Note, then such Interest Reset Date shall instead be the first Business
Day immediately following such auction date.
<PAGE>   15
                                                                              15

          The Calculation Date, if applicable, pertaining to any Interest
Determination Date will be the earlier of the tenth calendar day after such
Interest Determination Date, or the next succeeding Record Date after such
Interest Determination Date or, if either such day is not a Business Day, the
next succeeding Business Day.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date; provided, however, that if the
interest rate with respect to this Security is reset daily or weekly, interest
payable on any Interest Payment Date, other than interest payable on any date
on which principal hereof is payable, will include interest accrued to and
including the Record Date immediately preceding such Interest Payment Date, or
from and including the date of issue, if no interest has been paid with respect
to such Note, to and including the next preceding Regular Record Date.  Accrued
interest hereon from and including the Original Issue Date, or from but
excluding the last date to which interest hereon has been paid or duly provided
for, as the case may be, will be an amount calculated by multiplying the face
amount hereof by an accrued interest factor.  Such accrued interest factor will
be computed by adding the interest factor calculated for each day from and
including the Original Issue Date, or from but excluding the last date to which
interest shall have been paid or duly provided for, as the case may be, to and
including the date for which accrued interest is being calculated.  The
interest factor (expressed as a decimal rounded upwards, if necessary, to the
next higher one-hundred thousandth of a percentage point) for each such day
will be computed by dividing the interest rate (expressed as a decimal rounded
upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point) applicable to such day by 360, in the case of the Commercial
Paper Rate, LIBOR, the Federal Funds Rate, the Prime Rate or the CD Rate, or by
the actual number of days in the year, in the case of the Treasury Rate.  The
interest factor for Floating Rate Notes for which two or more interest rate
formulae are applicable will be calculated in the same manner as if only the
lowest, highest or average of, as the case may be, such interest rate formulae
applied.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or
<PAGE>   16
                                                                              16

other encumbrance upon any real or personal property located in the continental
United States of America without effectively providing that the Securities will
be secured equally and ratably with (or, at the option of the Company, prior
to) such indebtedness so long as such indebtedness shall be so secured or (ii)
enter into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, U.S. Government Obligations
(as defined in the Indenture) which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money or a
combination of money and U.S. Government Obligations in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on,
the Securities on the dates such payments are in accordance with the terms of
the Securities.

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

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66 2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this
<PAGE>   17
                                                                              17

Security and of any Security issued upon the registration or transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal, premium, if
any, or interest on this Security on or after the respective due dates
expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this Series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount will be issued to the designated transferee or transferees.
<PAGE>   18
                                                                              18

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

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

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

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

                           MEDIUM-TERM NOTE, SERIES A

                                  (Fixed Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of June 15, 1992, as supplemented as
of March 18, 1994 (herein called the "Indenture"), between the Company and
Chemical Bank, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
securities are, and are to be, authenticated and delivered.  This Security is
one of the series designated on the face hereof.

          This Security may not be redeemed prior to the Redemption Date set
forth on the face hereof.  If no Redemption Date is so set forth, this Security
is not redeemable prior to the Maturity Date.  On or after the Redemption Date
set forth on the face hereof, this Security is redeemable in whole or in part
in increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60  days prior to the date fixed for redemption,
all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable pricing supplement.

                                                                               5


          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States of
America without effectively providing that the Securities will be secured
equally and ratably with (or, at the option of the Company, prior to) such
indebtedness so long as such indebtedness shall be so secured or (ii) enter
into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee money or U.S. Government
Obligations (as defined in the Indenture), which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money or a combination of money and U.S. Government Obligations in an
amount sufficient to pay all the principal, premium, if any, and interest on,
the Securities on the dates such payments are due in accordance with the terms
of the Securities.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date.  Interest payments for this Security
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months.

          The interest rate on this Security will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general applicability.

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

                                                                               6

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66-2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal, premium, if
any, or interest on this Security on or after the respective due dates
expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

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

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

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

          The indebtedness evidenced by this Security is, to the extent and in
the manner set forth in the Indenture, expressly subordinated and subject in
right of payment to the prior payment in full of all Superior Indebtedness (as
defined in the Indenture) and this Security is issued subject to such
provisions of the Indenture, and each holder hereof, by the acceptance thereof,
agrees to and shall be bound by such provisions and authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate such subordination as provided in the Indenture and
appoints the Trustee his attorney-in- fact for any and all such purposes.

          This Security may not be redeemed prior to the Redemption Date set
forth in the applicable Pricing Supplement.  If no Redemption Date is so set
forth, this Security is not redeemable prior to the Maturity Date.  On or after
the Redemption Date set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60 days prior to the date fixed for redemption,
all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable Pricing Supplement.

          Commencing with the first Interest Reset Date specified in the
Prospectus Supplement or in the applicable Pricing Supplement following the
Original Issue Date, the rate at which interest on this Security is payable
shall be adjusted daily, weekly, monthly, quarterly, semi-annually or annually
as shown in the Prospectus Supplement or in the applicable Pricing Supplement
under "Interest Rate Reset Period"; provided, however, that the interest rate
in effect hereon for the 10 days immediately prior to the Maturity hereof,
shall be that in effect on the 10th day preceding the Maturity hereof.  Each
such adjusted rate shall be applicable on and after the Interest Reset Date to
which it relates, to but not including the next succeeding Interest Reset Date
or until Maturity, as the case may be.  If any Interest Reset Date specified on
the face hereof would otherwise be a day that is not a Business Day, such
Interest Reset Date shall be postponed to the next succeeding day that is a
Business Day, except that in the case of LIBOR Notes if such Business Day
is in the next succeeding calendar month, such Interest Reset Date shall be the
immediately preceding Business Day.  "Business Day" shall mean any day,
other than a Saturday or Sunday, that is neither a legal holiday nor a day on
which banking institutions are generally authorized or required by law or
regulation to close in The City of New York and (i) in respect of LIBOR Notes
in the City of London and which is a London Banking Day, (ii) with respect to 
Securities denominated or payable in a Specified Currency other than European 
Currency Units as defined and revised from time to time by the Council of the 
European Communities ("ECU"), in the financial center of the country issuing 
the Specified Currency and (iii) with respect to Securities denominated or 
payable in ECUs, in the financial center of each country that issues a 
component currency of

the ECU, and that is an ECU settlement day.  "London Banking Day" means any day
on which dealings in deposits in United States dollars are transacted in the
London interbank market.  Subject to applicable provisions of law and except as
specified herein, on each Interest Reset Date, the rate of interest on this
Security shall be the rate determined in accordance with the provisions of the
applicable heading below.

          The interest rate on this Security will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general applicability.

          DETERMINATION OF COMMERCIAL PAPER RATE.  The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Commercial Paper Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Commercial Paper Rate" means, with respect
to each Interest Determination Date specified on the face hereof, the Money
Market Yield (calculated as described below) of the rate on such date for
commercial paper having the Index Maturity specified on the face hereof as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "Commercial Paper".  In the event that such
rate is not published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
will be the Money Market Yield of the rate on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof 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 the Calculation Date pertaining to such Interest
Determination Date such rate is not yet available in either H.15(519) or the
Composite Quotations, then the Commercial Paper Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
Money Market Yield of the arithmetic mean (rounded to the next higher one
hundred thousandth of a percentage point) of the offered rates of three leading
dealers of commercial paper in The City of New York selected by the Calculation
Agent as of 11:00 A.M., New York City time, on such Interest
<PAGE>   8
                                                                               8

Determination Date for commercial paper having the Index Maturity specified on
the face hereof placed for an industrial issuer whose bond rating is "AA", or
the equivalent, from a nationally recognized rating agency; provided, however,
that if the dealers selected as aforesaid by the Calculation Agent are not
quoting as mentioned in this sentence, the Commercial Paper Rate will be the
Commercial Paper Rate in effect on such Interest Determination Date.

          "Money Market Yield" means a yield (expressed as  a percentage
rounded to the next higher one hundred thousandth of a percentage point)
calculated in accordance with the following formula:

               Money Market Yield =   D  x  360    x  100
                                    -------------
                                    360 - (D x M)

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.

          DETERMINATION OF PRIME RATE.  The interest rate payable with respect
to this Security shall be calculated by the Calculation Agent with reference to
the Prime Rate and the Spread or Spread Multiplier, if any, specified on the
face hereof.  "Prime Rate" means, with respect to each Interest Determination
Date specified on the face hereof, the rate published in H.15(519) for such
date opposite the caption "Bank Prime Loan."  If such rate is not yet published
by 3:00 P.M., New York City time, on the Calculation Date pertaining to such
Interest Determination Date, the Prime Rate for such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the rates of interest publicly announced
by each bank named on the Reuters Screen NYMF Page (as defined below) as such
bank's prime rate or base lending rate as in effect for such Interest
Determination Date as quoted on the Reuters Screen NYMF Page on such Interest
Determination Date, or, if fewer than four such rates appear on the Reuters
Screen NYMF Page for such Interest Determination Date, the rate shall be the
arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) of the prime rates quoted on the basis of the actual number
of days in the year divided by 360 as of the close of business on such Interest
Determination Date by at least two of the three major money center banks in The
City of New York selected by the Calculation Agent from which
<PAGE>   9
                                                                               9

quotations are requested.  If fewer than two quotations are provided, the Prime
Rate shall be calculated by the Calculation Agent and shall be determined as
the arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) on the basis of the prime rates in The City of New York by
the appropriate number of substitute banks or trust companies organized and
doing business under the laws of the United States, or any State thereof, in
each case having total equity capital of at least U.S. $500 million and being
subject to supervision or examination by Federal or State authority, selected
by the Calculation Agent to quote such rate or rates.

     "Reuters Screen NYMF Page" means the display designated as Page "NYMF" on
the Reuters Monitor Money Rates Services (or such other page as may replace the
NYMF Page on that service for the purpose of displaying prime rates or base
lending rates of major United States banks).

     If in any month or two consecutive months the Prime Rate is not published
in H.15(519) and the banks or trust companies selected as aforesaid are not
quoting as mentioned above, the "Prime Rate" for such Interest Reset Period
will be the same as the Prime Rate for the immediately preceding Interest Reset
Period (or, if there was no such Interest Reset Period, the rate of interest
payable on the Security for which the Prime Rate is being determined shall be
the Initial Interest Rate).  If this failure continues over three or more
consecutive months, the Prime Rate for each succeeding Interest Determination
Date until the maturity or redemption or repayment of such Securities or, if
earlier, until this failure ceases, shall be LIBOR determined as if such
Securities were LIBOR Notes, and the Spread, if any, shall be the number of
basis points specified in the applicable Pricing Supplement as the "Alternative
Rate Event Spread".

          DETERMINATION OF LIBOR.  The interest rate payable with respect to
this Security shall be calculated with reference to LIBOR and the Spread or
Spread Multiplier, if any, specified on the face hereof.  "LIBOR" will be
determined with respect to each Interest Determination Date specified on the
face hereof by the Calculation Agent in accordance with the following
provisions:  On each Interest Determination Date relating to a LIBOR Note,
LIBOR will be (a) where the applicable Pricing Supplement specifies
LIBOR-Telerate (as defined below) as the method for determining LIBOR, the rate
for deposits in U.S. dollars having the Index Maturity
<PAGE>   10
                                                                              10

specified on the face hereof which appears on the Telerate Page 3750 (as
defined below) as of 11:00 A.M., London time, on such Interest Determination
Date ("LIBOR- Telerate") or (b) where the applicable Pricing Supplement
specifies LIBOR-Reuters (as defined below) as the method of determining LIBOR,
the arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) of the offered rates for deposits in U.S. dollars having the
Index Maturity specified on the face hereof which appear on the Reuters Screen
LIBO Page (as defined below) as of 11:00 A.M., London time, on such Interest
Determination Date, provided that at least two such offered rates appear on the
Reuters Screen LIBO Page ("LIBOR-Reuters"); provided, however, that if the
method for determining LIBOR with respect to any LIBOR Note is not specified
therein or in the applicable Pricing Supplement, "LIBOR" means LIBOR-Telerate.

          If on any Interest Determination Date, (x) in any case where LIBOR-
Telerate applies, the rate for deposits in U.S. dollars having the applicable
Index Maturity does not appear on the Telerate Page 3750 as specified in (a)
above, or (y) in any case where LIBOR-Reuters applies, fewer than two offered
rates for deposits in U.S. dollars having the applicable Index Maturity appear
on the Reuters Screen LIBO Page as specified in (b) above, LIBOR 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 such Interest
Determination Date to prime banks in the London interbank market having the
Index Maturity specified on the face hereof and in a principal amount equal to
an amount that is representative for a single transaction in such market at
such time.  The Calculation Agent will request the principal London office of
each of such banks to provide a quotation of its rate.  If at least two such
quotations are provided, the rate in respect of such Interest Determination
Date will be the arithmetic mean (rounded to the next higher one hundred
thousandth of a percentage point) of the quotations.  If fewer than two
quotations are provided, LIBOR in respect of such Interest Determination Date
will be the arithmetic mean (rounded to the next higher one hundred thousandth
of a percentage point) 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 such Interest Determination Date for loans in U.S. dollars
to leading European banks, having the Index Maturity specified on the fact
hereof and in a principal amount equal to an amount that is

                                                                              11

representative for a single transaction in such market at such time; provided,
however, that if the banks selected as aforesaid by the Calculation Agent are
not quoting as described in this sentence, LIBOR for such Interest Reset Period
will be the same as LIBOR for the immediately preceding Interest Reset Period
(or, if there was no such Interest Reset Period, the rate of interest payable
on the LIBOR Notes for which LIBOR is being determined shall be the Initial
Interest Rate).

     "Telerate Page 3750" means the display page designated as page 3750 on the
Dow Jones Telerate Service (or such other page as may replace page 3750 on that
service for the purpose of displaying London interbank offered rates).

     "Reuters Screen LIBO Page" means the display page designated as page
"LIBO" on the Reuters Monitor Money Rates Service (or such other page as may
replace the LIBO page on that service for the purpose of displaying London
interbank offered rates).

          DETERMINATION OF TREASURY RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Treasury Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate for the
auction held on such date of direct obligations of the United States ("Treasury
bills") having the Index Maturity specified on the face hereof 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 Interest
Determination Date, the Treasury Rate will be the auction average rate,
expressed as a Bond Equivalent Yield (calculated as described below), for such
auction as otherwise announced by the United States Department of the Treasury.
If the results of the auction of Treasury bills having the Index Maturity
specified on the face hereof are not published or announced as provided above
by 3:00 P.M., New York City time, on such Calculation Date, or if no such
auction is held on such Interest Determination Date, then the Treasury Rate
shall be calculated by the Calculation Agent and shall be a yield to maturity,
expressed as a Bond Equivalent Yield, of the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the secondary
market bid rates as of approximately 3:30 P.M., New York City time, on such
Interest Determination
<PAGE>   12
                                                                              12

Date, of three leading primary United States government securities dealers
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 with respect to such
Interest Determination Date will be the Treasury Rate in effect on such
Interest Determination Date.

          "Bond Equivalent Yield" shall be a yield (expressed as a percentage
rounded to the next higher one-hundred thousandth of a percentage point)
calculated in accordance with the following formula:

               Bond Equivalent Yield =    D  x  N    x 100
                                       -------------
                                       360 - (D x M)

where "D" refers to the per annum rate for Treasury bills, quoted on a bank
discount basis and expressed as a decimal; "N" refers to the actual number of
days in the year for which interest is being calculated; and "M" refers to the
actual number of days in the interest period for which interest is being
calculated.

          DETERMINATION OF FEDERAL FUNDS RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Federal Funds Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Federal Funds Rate" means, with respect to
each Interest Determination Date specified on the face hereof, the rate on such
date for Federal Funds as published in H.15(519) under the heading "Federal
Funds (Effective)" or, if not so published by 3:00 P.M., New York City time, on
the Calculation Date pertaining to such Interest Determination Date, then the
Federal Funds Rate for such Interest Determination Date will be the rate on
such Interest Determination Date as published in the Composite Quotations under
the heading "Federal Funds/ Effective Rate".  If such rate is not yet published
in either H.15 (519) or Composite Quotations by 3:00 P.M., New York City time,
on the Calculation Date pertaining to such Interest Determination Date, then
the Federal Funds Rate for such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the rates for the last
transaction in overnight Federal Funds, as of 11:00 A.M., New York City time,
on such Interest Determination Date, arranged by three leading brokers of
<PAGE>   13
                                                                              13

Federal Funds transactions in The City of New York selected by the Calculation
Agent; provided, however, that if the brokers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Federal
Funds Rate in effect for the applicable period will be the same as the Federal
Funds Rate for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the
Securities for which such Federal Funds Rate is being determined shall be the
Initial Interest Rate).
          DETERMINATION OF CD RATE.  The interest rate payable with respect to
this Security shall be calculated by the Calculation Agent with reference to
the CD Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof.  "CD Rate" means, with respect to each Interest Determination Date, the
rate on such date for negotiable certificates of deposit having the Index
Maturity specified on the face hereof as published in H.15(519) under the
heading "CDs (Secondary Market)" or, if not so published by 3:00 P.M., New York
City time, on the Calculation Date pertaining to such Interest Determination
Date, the CD Rate will be the rate on such Interest Determination Date for
negotiable certificates of deposit of the Index Maturity specified on the face
hereof as published in the Composite Quotations under the heading "Certificates
of Deposit".  If such rate is not yet published in either H.15(519) or the
Composite Quotations by 3:00 P.M., New York City time, on such Calculation
Date, then the CD Rate on such Interest Determination Date will be calculated
by the Calculation Agent and will be the arithmetic mean (rounded to the
nearest one-hundred thousandth of a percentage point) of the secondary market
offered rates as of 10:00 A.M., New York City time, on such Interest
Determination Date, for certificates of deposit in the denomination of
$5,000,000 with a remaining maturity closest to the Index Maturity specified on
the fact hereof of three leading nonbank dealers in 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
center banks of the highest credit standing in the market for negotiable
certificates of deposit; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as set forth above, the CD
Rate in effect for the applicable period will be the same as the CD Rate for
the immediately preceding Interest Reset Period (or, if there was no such
Interest Reset Period, the rate of interest payable on the Securities for which
such CD Rate is being determined shall be the Initial Interest Rate).
<PAGE>   14
                                                                              14


          Notwithstanding the foregoing, the interest rate hereon shall not be
greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, shown on the face hereof.  The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing
on or before each Calculation Date and shall promptly thereafter notify the
Company and the Trustee of such interest rate.  Any such calculation by the
Calculation Agent shall be conclusive and binding on the Company, the Trustee
and the Holder of this Security, absent manifest error.

          The Calculation Agent will, upon the request of the Holder of this
Security, provide to such Holder the interest rate hereon then in effect and,
if determined, the interest rate which will become effective as of the next
Interest Reset Date.

          If any Interest Payment Date specified on the face hereof would
otherwise be a day that is not a Business Day, the Interest Payment Date shall
be postponed to the next day that is a Business Day, except in the case of
LIBOR Notes, if such London Banking Day is in the next succeeding calendar
month, such Interest Payment Date shall be the immediately preceding London
Banking Day.

          The Interest Determination Date pertaining to an Interest Reset Date
if the rate of interest on the Security shall be determined in accordance with
the provisions of the headings "Determination of Commercial Paper Rate",
"Determination of Prime Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate" above will be the second Business Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date on a LIBOR Note will be the second London Banking Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date if the rate of interest on the Security shall be determined in
accordance with the provisions of the heading "Determination of Treasury Rate"
above (the "Treasury Interest Determination Date") will be the day of the week
in which such Interest Reset Date falls on which Treasury bills would normally
be auctioned.  Treasury bills are usually sold at auction on the 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, as a result of a legal holiday, an auction is so held on
the preceding Friday, such Friday will be the Treasury Interest
<PAGE>   15
                                                                              15

Determination Date pertaining to the Interest Reset Date occurring in the next
succeeding week.  If an auction date shall fall on any Interest Reset Date for
a Treasury Rate Note, then such Interest Reset Date shall instead be the first
Business Day immediately following such auction date.

          The Calculation Date, if applicable, pertaining to any Interest
Determination Date will be the earlier of the tenth calendar day after such
Interest Determination Date, or the next succeeding Record Date after such
Interest Determination Date or, if either such day is not a Business Day, the
next succeeding Business Day.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date; provided, however, that if the
interest rate with respect to this Security is reset daily or weekly, interest
payable on any Interest Payment Date, other than interest payable on any date
on which principal hereof is payable, will include interest accrued to and
including the Record Date immediately preceding such Interest Payment Date, or
from and including the date of issue, if no interest has been paid with respect
to such Note, to and including the next preceding Regular Record Date.  Accrued
interest hereon from and including the Original Issue Date, or from but
excluding the last date to which interest hereon has been paid or duly provided
for, as the case may be, will be an amount calculated by multiplying the face
amount hereof by an accrued interest factor.  Such accrued interest factor will
be computed by adding the interest factor calculated for each day from and
including the Original Issue Date, or from but excluding the last date to which
interest shall have been paid or duly provided for, as the case may be, to and
including the date for which accrued interest is being calculated.  The
interest factor (expressed as a decimal rounded upwards, if necessary, to the
next higher one-hundred thousandth of a percentage point) for each such day
will be computed by dividing the interest rate (expressed as a decimal rounded
upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point) applicable to such day by 360, in the case of the Commercial
Paper Rate, LIBOR, the Federal Funds Rate, the Prime Rate or the CD Rate, or by
the actual number of days in the year, in the case of the Treasury Rate.  The
interest factor for Floating Rate Notes for which two or more interest rate
formulae are applicable will be calculated in the same manner as if only the
lowest, highest or average of, as the case may be, such interest rate formulae
applied.

                                                                              16

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States of
America without effectively providing that the Securities will be secured
equally and ratably with (or, at the option of the Company, prior to) such
indebtedness so long as such indebtedness shall be so secured or (ii) enter
into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, U.S. Government Obligations
(as defined in the Indenture) which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money or a
combination of money and U.S. Government Obligations in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on,
the Securities on the dates such payments are in accordance with the terms of
the Securities.

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

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with

the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time

outstanding, on behalf of the Holders of all Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration or transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal, premium, if
any, or interest on this Security on or after the respective due dates
expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and

thereupon one or more new Securities of this Series and of like tenor, of
authorized denominations and with like terms and conditions and for the same
aggregate principal amount will be issued to the designated transferee or
transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security is overdue, and neither

                                  (Fixed Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of             , 1994, (herein called
the "Indenture"), between the Company and ------------, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the securities are, and
are to be, authenticated and delivered.  This Security is one of the series
designated on the face hereof.

          The indebtedness evidenced by this Security is, to the extent and in
the manner set forth in the Indenture, expressly subordinated and subject in
right of payment to the prior payment in full of all Superior Indebtedness (as
defined in the Indenture) and this Security is issued subject to such
provisions of the Indenture, and each holder hereof, by the acceptance thereof,
agrees to and shall be bound by such provisions and authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate such subordination as provided in the Indenture and
appoints the Trustee his attorney-in- fact for any and all such purposes.

          This Security may not be redeemed prior to the Redemption Date set
forth on the face hereof.  If no Redemption Date is so set forth, this Security
is not redeemable prior to the Maturity Date.  On or after the Redemption Date
set forth on the face hereof, this Security is redeemable in whole or in part
in increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60
<PAGE>   5
                                                                               5

days prior to the date fixed for redemption, all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable pricing supplement.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States of
America without effectively providing that the Securities will be secured
equally and ratably with (or, at the option of the Company, prior to) such
indebtedness so long as such indebtedness shall be so secured or (ii) enter
into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee money or U.S. Government
Obligations (as defined in the Indenture), which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money or a combination of money and U.S. Government Obligations in an
amount sufficient to pay all the principal, premium, if any, and interest on,
the Securities on the dates such payments are due in accordance with the terms
of the Securities.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date.  Interest payments for this Security
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months.

                                                                               6


          The interest rate on this Security will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general applicability.

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

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66-2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the

enforcement of payment of the principal, premium, if any, or interest on this
Security on or after the respective due dates expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security is overdue,

   OLIN CORPORATION, a corporation duly organized and existing under the laws

multiplying by the Spread Multiplier (as such terms are defined below)
depending on whether a Spread or Spread Multiplier is designated above, until

monthly, quarterly, semi-annually or annually as specified in the Prospectus
Supplement or in the applicable Pricing Supplement, commencing with the first
Interest Payment Date specified above next succeeding the Original Issue Date
and thereafter on the Interest Payment Dates as specified therein, and on the
Maturity Date.  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, next preceding such Interest Payment Date; provided,
however, that interest payable at Maturity shall be payable to the Person to
whom principal shall be payable.  If any Interest Payment Date would fall on a
day that is not a Business Day, such Interest Payment Date will be the
following day that is a Business Day, except that, if the rate of interest on
the Security shall be determined in accordance with the provisions of the
heading "Determination of LIBOR" below (a "LIBOR Note"), and if such Business
Day is in the next succeeding calendar month, such Interest Payment Date shall
be the immediately preceding Business Day.  If the Maturity Date or any earlier
Redemption Date of a Security would fall 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 for
the period from and after such Maturity Date or Redemption Date, as the case
may be.

   Payment of the principal, premium, if any, and interest on this Security
will be made to the Depositary or its nominee, as a Holder thereof, in 
accordance with arrangements then in effect between the Trustee and the 
Depositary, in such coin or currency of the United States of America as at the 
time of payment is legal tender for payment of public and private debts; 
provided, however, that at the option of the Company payment of interest 
(except at Maturity) may be made by United States dollar check mailed to the 
address of the Person entitled thereto as such address shall appear in the 
Security Register (which, in the case of Book-Entry Notes, will be a Nominee of 
the Depositary). Payment of the principal, premium, if any, and interest on 
this Security due at Maturity will be made in immediately available funds upon 
surrender of this Security

                                (Floating Rate)


   This Security is one of a duly authorized issue of securities of the Company
(herein called the "Securities"), issued and to be issued in one or more series
under an Indenture, dated as of             , 1994, (herein called the
"Indenture"), between the Company and ____________, as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.  This Security is one of the series designated on
the face hereof.

   The indebtedness evidenced by this Security is, to the extent and in the
manner set forth in the Indenture, expressly subordinated and subject in right
of payment to the prior payment in full of all Superior Indebtedness (as
defined in the Indenture) and this Security is issued subject to such
provisions of the Indenture, and each holder hereof, by the acceptance thereof,
agrees to and shall be bound by such provisions and authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate such subordination as provided in the Indenture and
appoints the Trustee his attorney-in-fact for any and all such purposes.

   This Security may not be redeemed prior to the Redemption Date set forth in
the applicable Pricing Supplement.  If no Redemption Date is so set forth, this
Security is not redeemable prior to the Maturity Date.  On or after the
Redemption Date set forth in the Prospectus Supplement or in the applicable
Pricing Supplement, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

                                                                               6

   Notice of redemption will be given by mail to Holders of Securities, at
least 30 and not more than 60 days prior to the date fixed for redemption, all
as provided in the Indenture.

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

   The Securities of this series will not have a sinking fund unless otherwise
specified in the applicable Pricing Supplement.

   Commencing with the first Interest Reset Date specified in the Prospectus
Supplement or in the applicable Pricing Supplement following the Original Issue
Date, the rate at which interest on this Security is payable shall be adjusted
daily, weekly, monthly, quarterly, semi-annually or annually as shown in the
Prospectus Supplement or in the applicable Pricing Supplement under "Interest
Rate Reset Period"; provided, however, that the interest rate in effect hereon
for the 10 days immediately prior to the Maturity hereof, shall be that in
effect on the 10th day preceding the Maturity hereof.  Each such adjusted rate
shall be applicable on and after the Interest Reset Date to which it relates,
to but not including the next succeeding Interest Reset Date or until Maturity,
as the case may be.  If any Interest Reset Date specified on the face hereof
would otherwise be a day that is not a Business Day, such Interest Reset Date
shall be postponed to the next succeeding day that is a Business Day, except
that in the case of LIBOR Notes if such Business Day is in the next succeeding
calendar month, such Interest Reset Date shall be the immediately preceding
Business Day.  "Business Day" shall mean any day, other than a Saturday or
Sunday, that is neither a legal holiday nor a day on which banking institutions
are generally authorized or required by law or regulation to close in The City
of New York and (i) in respect of LIBOR Notes in the City of London and is a
London Banking Day, (ii) with respect to Securities denominated or payable in a
Specified Currency other than European Currency Units as defined and revised
from time to time by the Council of the European Communities ("ECU"), in the
financial center of the country issuing the Specified Currency and (iii) with
respect to Securities denominated or payable in ECUs, in the financial center
of each country that issues a component

currency of the ECU, and that is an ECU settlement day.  "London Banking Day"
means any day on which dealings in deposits in United States dollars are
transacted in the London interbank market.  Subject to applicable provisions of
law and except as specified herein, on each Interest Reset Date, the rate of
interest on this Security shall be the rate determined in accordance with the
provisions of the applicable heading below.

   The interest rate on this Security will in no event be higher than the
maximum rate permitted by New York law as the same may be modified by United
States law of general applicability.

   DETERMINATION OF COMMERCIAL PAPER RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Commercial Paper Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Commercial Paper Rate" means, with respect
to each Interest Determination Date specified on the face hereof, the Money
Market Yield (calculated as described below) of the rate on such date for
commercial paper having the Index Maturity specified on the face hereof as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "Commercial Paper".  In the event that such
rate is not published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
will be the Money Market Yield of the rate on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof 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 the Calculation Date pertaining to such Interest
Determination Date such rate is not yet available in either H.15(519) or the
Composite Quotations, then the Commercial Paper Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
Money Market Yield of the arithmetic mean (rounded to the next higher one
hundred thousandth of a percentage point) of the offered rates of three leading
dealers of commercial paper in The City of New York selected by the Calculation
Agent as of 11:00 A.M., New York City time, on such Interest
<PAGE>   8
                                                                               8

Determination Date for commercial paper having the Index Maturity specified on
the face hereof placed for an industrial issuer whose bond rating is "AA", or
the equivalent, from a nationally recognized rating agency; provided, however,
that if the dealers selected as aforesaid by the Calculation Agent are not
quoting as mentioned in this sentence, the Commercial Paper Rate will be the
Commercial Paper Rate in effect on such Interest Determination Date.

                 "Money Market Yield" means a yield (expressed as  a percentage 
rounded to the next higher one hundred thousandth of a percentage point) 
calculated in accordance with the following formula:

                 Money Market Yield =   D  x  360    x  100
                                      -------------
                                      360 - (D x M)

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.

                 DETERMINATION OF PRIME RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Prime Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Prime Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate published in
H.15(519) for such date opposite the caption "Bank Prime Loan."  If such rate
is not yet published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, the Prime Rate for such
Interest Determination Date will be the arithmetic mean (rounded to the next
higher one hundred thousandth of a percentage point) of the rates of interest
publicly announced by each bank named on the Reuters Screen NYMF Page (as
defined below) as such bank's prime rate or base lending rate as in effect for
such Interest Determination Date as quoted on the Reuters Screen NYMF Page on
such Interest Determination Date, or, if fewer than four such rates appear on
the Reuters Screen NYMF Page for such Interest Determination Date, the rate
shall be the arithmetic mean (rounded to the next higher one hundred thousandth
of a percentage point) of the prime rates quoted on the basis of the actual
number of days in the year divided by 360 as of the close of business on such
Interest Determination Date by at least two of the three major money center
banks in The City of New York selected by the Calculation Agent from which

                                                                               9

quotations are requested.  If fewer than two quotations are provided, the Prime
Rate shall be calculated by the Calculation Agent and shall be determined as
the arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) on the basis of the prime rates in The City of New York by
the appropriate number of substitute banks or trust companies organized and
doing business under the laws of the United States, or any State thereof, in
each case having total equity capital of at least U.S. $500 million and being
subject to supervision or examination by Federal or State authority, selected
by the Calculation Agent to quote such rate or rates.

         "Reuters Screen NYMF Page" means the display designated as Page "NYMF"
on the Reuters Monitor Money Rates Services (or such other page as may replace
the NYMF Page on that service for the purpose of displaying prime rates or base
lending rates of major United States banks).

         If in any month or two consecutive months the Prime Rate is not
published in H.15(519) and the banks or trust companies selected as aforesaid
are not quoting as mentioned above, the "Prime Rate" for such Interest Reset
Period will be the same as the Prime Rate for the immediately preceding
Interest Reset Period (or, if there was no such Interest Reset Period, the rate
of interest payable on the Security for which the Prime Rate is being
determined shall be the Initial Interest Rate).  If this failure continues over
three or more consecutive months, the Prime Rate for each succeeding Interest
Determination Date until the maturity or redemption or repayment of such
Securities or, if earlier, until this failure ceases, shall be LIBOR determined
as if such Securities were LIBOR Notes, and the Spread, if any, shall be the
number of basis points specified in the applicable Pricing Supplement as the
"Alternative Rate Event Spread".

                 DETERMINATION OF LIBOR.  The interest rate payable with
respect to this Security shall be calculated with reference to LIBOR and the
Spread or Spread Multiplier, if any, specified on the face hereof.  "LIBOR"
will be determined with respect to each Interest Determination Date specified
on the face hereof by the Calculation Agent in accordance with the following
provisions:  On each Interest Determination Date relating to a LIBOR Note,
LIBOR will be (a) where the applicable Pricing Supplement specifies
LIBOR-Telerate (as defined below) as the method for determining LIBOR, the rate
for deposits in U.S. dollars having the Index Maturity
<PAGE>   10
                                                                              10

specified on the face hereof which appears on the Telerate Page 3750 (as
defined below) as of 11:00 A.M., London time, on such Interest Determination
Date ("LIBOR-Telerate") or (b) where the applicable Pricing Supplement
specifies LIBOR-Reuters (as defined below) as the method of determining LIBOR,
the arithmetic mean (rounded to the next higher one hundred thousandth of a
percentage point) of the offered rates for deposits in U.S. dollars having the
Index Maturity specified on the face hereof which appear on the Reuters Screen
LIBO Page (as defined below) as of 11:00 A.M., London time, on such Interest
Determination Date, provided that at least two such offered rates appear on the
Reuters Screen LIBO Page ("LIBOR-Reuters"); provided, however, that if the
method for determining LIBOR with respect to any LIBOR Note is not specified
therein or in the applicable Pricing Supplement, "LIBOR" means LIBOR-Telerate.

                 If on any Interest Determination Date, (x) in any case where
LIBOR-Telerate applies, the rate for deposits in U.S. dollars having the
applicable Index Maturity does not appear on the Telerate Page 3750 as
specified in (a) above, or (y) in any case where LIBOR- Reuters applies, fewer
than two offered rates for deposits in U.S. dollars having the applicable Index
Maturity appear on the Reuters Screen LIBO Page as specified in (b) above,
LIBOR 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 such
Interest Determination Date to prime banks in the London interbank market
having the Index Maturity specified on the face hereof and in a principal
amount equal to an amount that is representative for a single transaction in
such market at such time.  The Calculation Agent will request the principal
London office of each of such banks to provide a quotation of its rate.  If at
least two such quotations are provided, the rate in respect of such Interest
Determination Date will be the arithmetic mean (rounded to the next higher one
hundred thousandth of a percentage point) of the quotations.  If fewer than two
quotations are provided, LIBOR in respect of such Interest Determination Date
will be the arithmetic mean (rounded to the next higher one hundred thousandth
of a percentage point) 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 such Interest Determination Date for loans in U.S. dollars
to leading European banks, having the Index Maturity specified on the fact
hereof and in a principal amount equal to an amount that is

                                                                              11

representative for a single transaction in such market at such time; provided,
however, that if the banks selected as aforesaid by the Calculation Agent are
not quoting as described in this sentence, LIBOR for such Interest Reset Period
will be the same as LIBOR for the immediately preceding Interest Reset Period
(or, if there was no such Interest Reset Period, the rate of interest payable
on the LIBOR Notes for which LIBOR is being determined shall be the Initial
Interest Rate).

         "Telerate Page 3750" means the display page designated as page 3750 on
the Dow Jones Telerate Service (or such other page as may replace page 3750 on
that service for the purpose of displaying London interbank offered rates).

         "Reuters Screen LIBO Page" means the display page designated as page
"LIBO" on the Reuters Monitor Money Rates Service (or such other page as may
replace the LIBO page on that service for the purpose of displaying London
interbank offered rates).

                 DETERMINATION OF TREASURY RATE.  The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Treasury Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate for the
auction held on such date of direct obligations of the United States ("Treasury
bills") having the Index Maturity specified on the face hereof 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 Interest
Determination Date, the Treasury Rate will be the auction average rate,
expressed as a Bond Equivalent Yield (calculated as described below), for such
auction as otherwise announced by the United States Department of the Treasury.
If the results of the auction of Treasury bills having the Index Maturity
specified on the face hereof are not published or announced as provided above
by 3:00 P.M., New York City time, on such Calculation Date, or if no such
auction is held on such Interest Determination Date, then the Treasury Rate
shall be calculated by the Calculation Agent and shall be a yield to maturity,
expressed as a Bond Equivalent Yield, of the arithmetic mean (rounded to the
next higher one hundred thousandth of a percentage point) of the secondary
market bid rates as of approximately 3:30 P.M., New York City time, on such
Interest Determination
<PAGE>   12
                                                                              12

Date, of three leading primary United States government securities dealers
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 with respect to such
Interest Determination Date will be the Treasury Rate in effect on such
Interest Determination Date.

                 "Bond Equivalent Yield" shall be a yield (expressed as a
percentage rounded to the next higher one-hundred thousandth of a percentage
point) calculated in accordance with the following formula:

                          Bond Equivalent Yield =    D  x  N    x 100
                                                  -------------
                                                  360 - (D x M)

where "D" refers to the per annum rate for Treasury bills, quoted on a bank
discount basis and expressed as a decimal; "N" refers to the actual number of
days in the year for which interest is being calculated; and "M" refers to the
actual number of days in the interest period for which interest is being
calculated.

                 DETERMINATION OF FEDERAL FUNDS RATE.  The interest rate
payable with respect to this Security shall be calculated by the Calculation
Agent with reference to the Federal Funds Rate and the Spread or Spread
Multiplier, if any, specified on the face hereof.  "Federal Funds Rate" means,
with respect to each Interest Determination Date specified on the face hereof,
the rate on such date for Federal Funds as published in H.15(519) under the
heading "Federal Funds (Effective)" or, if not so published by 3:00 P.M., New
York City time, on the Calculation Date pertaining to such Interest
Determination Date, then the Federal Funds Rate for such Interest Determination
Date will be the rate on such Interest Determination Date as published in the
Composite Quotations under the heading "Federal Funds/ Effective Rate".  If
such rate is not yet published in either H.15 (519) or Composite Quotations by
3:00 P.M., New York City time, on the Calculation Date pertaining to such
Interest Determination Date, then the Federal Funds Rate for such Interest
Determination Date will be calculated by the Calculation Agent and will be the
arithmetic mean (rounded to the nearest one-hundred thousandth of a percentage
point) of the rates for the last transaction in overnight Federal Funds, as of
11:00 A.M., New York City time, on such Interest Determination Date, arranged
by three leading brokers of
<PAGE>   13
                                                                              13

Federal Funds transactions in The City of New York selected by the Calculation
Agent; provided, however, that if the brokers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Federal
Funds Rate in effect for the applicable period will be the same as the Federal
Funds Rate for the immediately preceding Interest Reset Period (or, if there
was no such Interest Reset Period, the rate of interest payable on the
Securities for which such Federal Funds Rate is being determined shall be the
Initial Interest Rate).

                 DETERMINATION OF CD RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the CD Rate and the Spread or Spread Multiplier, if any, specified
on the face hereof.  "CD Rate" means, with respect to each Interest
Determination Date, the rate on such date for negotiable certificates of
deposit having the Index Maturity specified on the face hereof as published in
H.15(519) under the heading "CDs (Secondary Market)" or, if not so published by
3:00 P.M., New York City time, on the Calculation Date pertaining to such
Interest Determination Date, the CD Rate will be the rate on such Interest
Determination Date for negotiable certificates of deposit of the Index Maturity
specified on the face hereof as published in the Composite Quotations under the
heading "Certificates of Deposit".  If such rate is not yet published in either
H.15(519) or the Composite Quotations by 3:00 P.M., New York City time, on such
Calculation Date, then the CD Rate on such Interest Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean (rounded to
the nearest one-hundred thousandth of a percentage point) of the secondary
market offered rates as of 10:00 A.M., New York City time, on such Interest
Determination Date, for certificates of deposit in the denomination of
$5,000,000 with a remaining maturity closest to the Index Maturity specified on
the fact hereof of three leading nonbank dealers in 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
center banks of the highest credit standing in the market for negotiable
certificates of deposit; provided, however, that if the dealers selected as
aforesaid by the Calculation Agent are not quoting as set forth above, the CD
Rate in effect for the applicable period will be the same as the CD Rate for
the immediately preceding Interest Reset Period (or, if there was no such
Interest Reset Period, the rate of interest payable on the Securities
<PAGE>   14
                                                                              14

for which such CD Rate is being determined shall be the Initial Interest Rate).

                 Notwithstanding the foregoing, the interest rate hereon shall
not be greater than the Maximum Interest Rate, if any, or less than the Minimum
Interest Rate, if any, shown on the face hereof.  The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing
on or before each Calculation Date and shall promptly thereafter notify the
Company and the Trustee of such interest rate.  Any such calculation by the
Calculation Agent shall be conclusive and binding on the Company, the Trustee
and the Holder of this Security, absent manifest error.

                 The Calculation Agent will, upon the request of the Holder of
this Security, provide to such Holder the interest rate hereon then in effect
and, if determined, the interest rate which will become effective as of the
next Interest Reset Date.

                 If any Interest Payment Date specified on the face hereof
would otherwise be a day that is not a Business Day, the Interest Payment Date
shall be postponed to the next day that is a Business Day, except in the case
of LIBOR Notes, if such London Banking Day is in the next succeeding calendar
month, such Interest Payment Date shall be the immediately preceding London
Banking Day.

                 The Interest Determination Date pertaining to an Interest
Reset Date if the rate of interest on the Security shall be determined in
accordance with the provisions of the headings "Determination of Commercial
Paper Rate", "Determination of Prime Rate", "Determination of Federal Funds
Rate" or "Determination of CD Rate" above will be the second Business Day
preceding such Interest Reset Date.  The Interest Determination Date pertaining
to an Interest Reset Date on a LIBOR Note will be the second London Banking Day
preceding such Interest Reset Date.  The Interest Determination Date pertaining
to an Interest Reset Date if the rate of interest on the Security shall be
determined in accordance with the provisions of the heading "Determination of
Treasury Rate" above (the "Treasury Interest Determination Date") will be the
day of the week in which such Interest Reset Date falls on which Treasury bills
would normally be auctioned.  Treasury bills are usually sold at auction on the
Monday of each week, unless that day is a legal holiday, in which case the
auction is usually held on the following Tuesday, except
<PAGE>   15
                                                                              15

that such auction may be held on the preceding Friday.  If, as a result of a
legal holiday, an auction is so held on the preceding Friday, such Friday will
be the Treasury Interest Determination Date pertaining to the Interest Reset
Date occurring in the next succeeding week.  If an auction date shall fall on
any Interest Reset Date for a Treasury Rate Note, then such Interest Reset Date
shall instead be the first Business Day immediately following such auction
date.

                 The Calculation Date, if applicable, pertaining to any
Interest Determination Date will be the earlier of the tenth calendar day after
such Interest Determination Date, or the next succeeding Record Date after such
Interest Determination Date or, if either such day is not a Business Day, the
next succeeding Business Day.

                 Interest payments for this Security will include interest
accrued to but excluding the Interest Payment Date; provided, however, that if
the interest rate with respect to this Security is reset daily or weekly,
interest payable on any Interest Payment Date, other than interest payable on
any date on which principal hereof is payable, will include interest accrued to
and including the Record Date immediately preceding such Interest Payment Date,
or from and including the date of issue, if no interest has been paid with
respect to such Note, to and including the next preceding Regular Record Date.
Accrued interest hereon from and including the Original Issue Date, or from but
excluding the last date to which interest hereon has been paid or duly provided
for, as the case may be, will be an amount calculated by multiplying the face
amount hereof by an accrued interest factor.  Such accrued interest factor will
be computed by adding the interest factor calculated for each day from and
including the Original Issue Date, or from but excluding the last date to which
interest shall have been paid or duly provided for, as the case may be, to and
including the date for which accrued interest is being calculated.  The
interest factor (expressed as a decimal rounded upwards, if necessary, to the
next higher one-hundred thousandth of a percentage point) for each such day
will be computed by dividing the interest rate (expressed as a decimal rounded
upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point) applicable to such day by 360, in the case of the Commercial
Paper Rate, LIBOR, the Federal Funds Rate, the Prime Rate or the CD Rate, or by
the actual number of days in the year, in the case of the Treasury Rate.  The
interest factor for Floating Rate Notes for which two or more interest rate
formulae are applicable will be calculated in the same manner
<PAGE>   16
                                                                              16

as if only the lowest, highest or average of, as the case may be, such interest
rate formulae applied.

                 Subject to a number of important qualifications and exceptions
set forth in the Indenture, the Indenture provides that neither the Company nor
any Subsidiary (as defined in the Indenture) will (i) issue, assume or
guarantee any notes, bonds, debentures or other similar evidences of
indebtedness for money borrowed secured by a mortgage, lien, pledge or other
encumbrance upon any real or personal property located in the continental
United States of America without effectively providing that the Securities will
be secured equally and ratably with (or, at the option of the Company, prior
to) such indebtedness so long as such indebtedness shall be so secured or (ii)
enter into any Sale and Lease-Back Transactions (as defined in the Indenture).

                 The Indenture also provides that the Company at its option (a)
will be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, U.S. Government Obligations
(as defined in the Indenture) which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money or a
combination of money and U.S. Government Obligations in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on,
the Securities on the dates such payments are in accordance with the terms of
the Securities.

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

                 The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Securities at the time Outstanding of
<PAGE>   17
                                                                              17

each series to be affected.  The Indenture also contains provisions permitting
the Holders of specified percentages in principal amount of the Securities of
each series at the time outstanding, on behalf of the Holders of all Securities
of such series, to waive compliance by the Company with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences.  Any such consent or waiver by the Holder of this Security shall
be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration or transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

                 As set forth in, and subject to, the provisions of the
Indenture, no Holder of any Security of this series will have any right to
institute any proceeding with respect to the Indenture or for any remedy
thereunder, unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to this series,
the Holders of not less than 25% in principal amount of the Outstanding
Securities of this series shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as trustee,
the Trustee shall not have received from the Holders of a majority in principal
amount of the Outstanding Securities of this series a direction inconsistent
with such request and the Trustee shall have failed to institute such
proceeding within 60 days; provided, however, that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal, premium, if any, or interest on this Security on or after the
respective due dates expressed herein.

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

                 As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the corporate trust office of the Trustee or such other office or
agency as may be designated by the Company in the Borough of Manhattan, The
City of New York, duly endorsed by, or accompanied by a

written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this Series
and of like tenor, of authorized denominations and with like terms and
conditions and for the same aggregate principal amount will be issued to the
designated transferee or transferees.

                 The Securities of this series are issuable only in registered
form, without coupons, in denominations of $1,000 and any integral multiple of
$1,000 in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

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

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

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

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

Pricing Supplement, as the case may be, next preceding such Interest Payment

the Person to whom principal shall be payable.  If any Interest Payment Date
would fall on a day that is not a Business Day, such Interest Payment Date will
be the following day that is a Business Day.  If the Maturity Date or any
earlier Redemption Date of a Security would fall 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 for the period from and after such Maturity Date, or Redemption Date, as
the case may be.

          Payment of the principal, premium, if any, and interest on this
Security will be made to the Depositary, or its nominee, as Holder thereof, in
accordance with arrangements then in effect between the Trustee and the
Depositary, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company, payment of interest
(except at Maturity) may be made by United States dollar check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register (which, in the case of Book-Entry Notes, will be a nominee of
the Depositary).  Payment of the principal, premium, if any, and interest on
this Security due at Maturity will be made in immediately available funds upon
surrender of this Security; provided that this Security is presented to the
paying agent in time for the Paying Agent to make such payment in accordance
with its normal procedures.  "Maturity" shall mean the date on which the
principal of this Security or an installment of principal becomes due, whether
on the Maturity Date specified above, upon redemption or otherwise.

                                  (Fixed Rate)


          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of             , 1994, (herein called
the "Indenture"), between the Company and -------------, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the securities are, and
are to be, authenticated and delivered.  This Security is one of the series
designated on the face hereof.

          The indebtedness evidenced by this Security is, to the extent and in
the manner set forth in the Indenture, expressly subordinated and subject in
right of payment to the prior payment in full of all Superior Indebtedness (as
defined in the Indenture) and this Security is issued subject to such
provisions of the Indenture, and each holder hereof, by the acceptance thereof,
agrees to and shall be bound by such provisions and authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate such subordination as provided in the Indenture and
appoints the Trustee his attorney-in- fact for any and all such purposes.

          This Security may not be redeemed prior to the Redemption Date set
forth on the face hereof.  If no Redemption Date is so set forth, this Security
is not redeemable prior to the Maturity Date.  On or after the Redemption Date
set forth on the face hereof, this Security is redeemable in whole or in part
in increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
at least 30 and not more than 60

                                                                               5

days prior to the date fixed for redemption, all as provided in the Indenture.

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

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable pricing supplement.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides that neither the Company nor any
Subsidiary (as defined in the Indenture) will (i) issue, assume or guarantee
any notes, bonds, debentures or other similar evidences of indebtedness for
money borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States of
America without effectively providing that the Securities will be secured
equally and ratably with (or, at the option of the Company, prior to) such
indebtedness so long as such indebtedness shall be so secured or (ii) enter
into any Sale and Lease-Back Transactions (as defined in the Indenture).

          The Indenture also provides that the Company at its option (a) will
be Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee money or U.S. Government
Obligations (as defined in the Indenture), which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money or a combination of money and U.S. Government Obligations in an
amount sufficient to pay all the principal, premium, if any, and interest on,
the Securities on the dates such payments are due in accordance with the terms
of the Securities.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date.  Interest payments for this Security
shall be computed and paid on the basis of a 360-day year of twelve 30-day
months.

          The interest rate on this Security will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general applicability.

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

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66-2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not
less than 25% in principal amount of the Outstanding Securities of this series
shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the
Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the

enforcement of payment of the principal, premium, if any, or interest on this
Security on or after the respective due dates expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized
denominations and with like terms and conditions and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination and with like terms and conditions, as
requested by the Holder surrendering the same.

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

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security is overdue,

and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary.

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

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

IMPORTANT NOTICE:  When you sign your name to this Assignment Form without
filling in the name of your "Assignee" or "Attorney", this stock certificate
becomes fully negotiable, similar to a check endorsed in blank.  Therefore, to
safeguard a signed certificate, it is recommended that you either (i) fill in
the name of the new owner in the "Assignee" blank, or (ii) if you are sending
the signed certificate to your bank or broker, fill in the name of the bank or
broker in the "Attorney" blank.  Alternatively, instead of using this
Assignment Form, you may sign a separate "stock power" form and then mail the
unsigned stock certificate and the signed "stock power" in separate envelopes.
For added protection, use certified or registered mail for a stock certificate.
        Keep this certificate in a safe place.  If it is lost, stolen or
destroyed, the Company will require a bond of indemnity as a condition to the
issuance of a replacement certificate.

        This certificate also evidences and entitles the holder hereof to
certain Rights as set forth in the Rights Agreement between Olin Corporation
and Manufacturers Hanover Trust Company (now Chemical Bank) dated as of
February 27, 1986 (the "Rights Agreement), the terms of which are hereby
incorporated herein by reference and a copy of which is on file at the
principal offices of Olin Corporation.  Under certain circumstances, as set
forth in the Rights Agreement, such Rights will be evidenced by separate
certificates and will no longer be evidenced by this certificate.  Olin
Corporation will mail to the holder of this certificate a copy of the Rights
Agreement, as in effect on the date of mailing, without charge promptly after
receipt of a written request therefor.  Under certain circumstances set forth
in the Rights Agreement, Rights issued to, or held by, any Person who is, was
or becomes an Acquiring Person or any Affiliate or Associate thereof (as such
terms are defined in the Rights Agreement), whether currently held by or on
behalf of such Person or by any subsequent holder, may become null and void.

IMPORTANT NOTICE:  When you sign your name to this Assignment Form without
filling in the name of your "Assignee" or "Attorney", this stock certificate
becomes fully negotiable, similar to a check endorsed in blank.  Therefore, to
safeguard a signed certificate, it is recommended that you either (i) fill in
the name of the new owner in the "Assignee" blank, or (ii) if you are sending
the signed certificate to your bank or broker, fill in the name of the bank or
broker in the "Attorney" blank.  Alternatively, instead of using this
Assignment Form, you may sign a separate "stock power" form and then mail the
unsigned stock certificate and the signed "stock power" in separate envelopes.
For added protection, use certified or registered mail for a stock certificate.
        Keep this certificate in a safe place.  If it is lost, stolen or
destroyed, the Company will require a bond of indemnity as a condition to the
issuance of a replacement certificate.

                   PREFERRED STOCK WARRANTS, COMMON STOCK AND
                             COMMON STOCK WARRANTS
 
Dear Sirs:
 
     As General Counsel-Corporate Resources and Secretary of Olin Corporation, a
Virginia corporation (the "Company"), I have examined and am familiar with the
Restated Articles of Incorporation of the Company, as amended, and the By-laws
of the Company, as amended. I am also familiar with the corporate proceedings
taken by the Board of Directors to authorize the Registration Statement on Form
S-3 (the "Registration Statement") being filed by the Company on the date hereof
with the Securities and Exchange Commission under the Securities Act of 1933
(the "Securities Act") with respect to $325,000,000 aggregate initial offering
price of Debt Securities, warrants to purchase Debt Securities (the "Debt
Warrants"), Preferred Stock, warrants to purchase shares of Preferred Stock (the
"Preferred Stock Warrants"), Common Stock and warrants to purchase Common Stock
(the "Common Stock Warrants"), for issuance from time to time pursuant to Rule
415 under the Securities Act.
 
     In connection with the foregoing, I have examined originals, or copies
certified or otherwise identified to my satisfaction, of such documents,
corporate records and other instruments as I have deemed necessary or
appropriate for the purpose of this opinion.
 
     Based upon the foregoing, I am of the opinion that:
 
          1. The Debt Securities, when duly authorized, executed, authenticated
     and delivered against payment therefor, or in the case of Debt Securities
     issuable upon the exercise of Debt Warrants, upon receipt of the exercise
     price of the Debt Warrants, will be legally issued and will constitute
     binding obligations of the Company in accordance with their terms.
 
          2. The shares of Preferred Stock and the shares of Common Stock, when
     duly authorized, executed and issued for consideration having a value not
     less than the par value thereof, or in the case of Preferred Stock or
     Common Stock issuable upon the exercise of Preferred Stock Warrants or
     Common Stock Warrants, as the case may be, when issued for consideration
     having a value not less than the par value thereof, will be legally issued,
     fully paid and nonassessable.
 
          3. The Debt Warrants, Preferred Stock Warrants and the Common Stock
     Warrants, when duly authorized, executed, countersigned and delivered
     against payment therefor, will be legally issued and will constitute
     binding obligations of the Company in accordance with their terms.
 
     The opinions set forth in paragraphs 1 and 3 above are subject to
applicable bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium or other laws affecting creditors' rights generally from time to time
in effect.

     I know that I am referred to under the heading "Legal Matters" in the

Statement and to the use of this opinion for filing as an exhibit to the
Registration Statement.

(a) In 1993, the Company recorded an after-tax charge of $132 million for
personnel reductions, business restructurings involving consolidations and
re-alignments within divisions, costs at sites of discontinued businesses,
future environmental liabilities, and other charges.  In 1991, the Company
recorded an after-tax charge of $80 million to cover losses on the disposition
and write-down of certain businesses and costs of personnel reductions.

(b) The ratio of earnings to combined fixed charges and preferred stock
dividends has been computed based upon income before taxes and fixed charges
included in income (loss) after eliminating the amortization of capitalized
interest and the undistributed (earnings) losses of less than 50%-owned
affiliates.  Fixed charges include interest and that portion of rental expense
deemed to represent interest.

(c) In the twelve months ended December 31, 1993 and December 31, 1991,
earnings were inadequate to cover combined fixed charges and preferred stock
dividends by $172 million and $38 million, respectively, as a result of the
1993 and 1991 charges.
