                              DESCRIPTION OF NOTES
 
     The Notes offered hereby will be issued under the Indenture dated as of
January 15, 1990, referred to in the accompanying Prospectus (such Indenture, as
amended by the Trust Indenture Reform Act of 1990, the "Indenture") between the
Company and The Chase Manhattan Bank (National Association), as Trustee (the
"Trustee"). The summary contained herein of certain provisions of the Notes does
not purport to be complete and is qualified in its entirety by reference to the
provisions of the Indenture and the form of Notes, each of which has been filed
as an exhibit to the Registration Statements of which the accompanying
Prospectus is a part.
 
     The Notes are referred to in the accompanying Prospectus as the "Offered
Debt Securities." 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 of the Offered Debt Securities set forth
under the heading "Description of the Debt Securities" in the accompanying
Prospectus, to which description reference is hereby made.
 
     Except as otherwise defined herein, capitalized terms set forth below have
the meanings specified in the Indenture or the Notes. Currency amounts in this
Prospectus Supplement, the accompanying Prospectus and any Pricing Supplement
are stated in U.S. dollars.
 
GENERAL
 
     The Notes constitute a single series for purposes of the Indenture and are
currently limited to an aggregate principal amount of $500,000,000, including
the $197,900,000 aggregate principal amount of Notes issued prior to the date
hereof. The foregoing limit, however, may be increased by the Company if in the
future it determines that it may wish to sell additional Notes. The Company may
from time to time sell additional series of Debt Securities, including
additional series of medium-term notes.
 
     The Notes are offered on a continuing basis and will mature on any day
(whether or not a Business Day) from nine months to 15 years from their date of
issue, as selected by the initial purchaser and agreed to by the Company, but
may be subject to redemption prior to maturity as set forth under "Redemption"
below. "Business Day" means any day that is not a Saturday or Sunday and that,
in New York, New York, is not a day on which banking institutions are authorized
by law to close.
 
     Each Note will be issued initially as either a Book-Entry Note (evidenced
by a Global Security) or as a Certificated Note (evidenced by a certificate
registered in the name of the registered holder). Except as set forth under
"Book-Entry System" below, Book-Entry Notes will not be issuable in definitive
form. Notes will be denominated in U.S. dollars and will be issued in
denominations of $100,000 and integral multiples of $1,000 in excess thereof.
 
     The Notes may be presented for payment of principal and interest, transfer
of the Notes will be registrable and the Notes will be exchangeable at the
agency in New York, New York, maintained by the Company for such purpose;
provided that Book-Entry Notes will be transferable and exchangeable only in the
manner and to the extent set forth under "Book-Entry System" below. On the date
hereof, the agent for the payment, transfer and exchange of the Notes (the
"Paying Agent") is The Chase Manhattan Bank (National Association), acting
through its corporate trust office at 4 Chase Metrotech Center, Brooklyn, New
York 11245.
 
     The Pricing Supplement relating to each Note will describe the following
terms: (i) the price (expressed as a percentage of the aggregate principal
amount thereof) at which such Note will be issued and sold, if other than 100%;
(ii) the date on which such Note will be issued; (iii) the date on which such
Note will mature; (iv) the rate per annum at which such Note will bear interest;
(v) whether such Note may be redeemed prior to maturity and, if so, the
provisions relating to such redemption; (vi) whether such Note will be issued
initially as a Book-Entry Note or a Certificated Note; and (vii) any other terms
of such Note not inconsistent with the provisions of the Indenture.

INTEREST AND INTEREST RATES
 
     Each Note will bear interest from its date of issue or from the most recent
Interest Payment Date (hereinafter defined) to which interest on such Note has
been paid or duly provided for, at a fixed rate per annum stated therein and in
the applicable Pricing Supplement, until the principal thereof is paid or made
available for payment. Interest will be computed on the basis of a 360-day year
of twelve 30-day months, and, unless otherwise specified in the applicable
Pricing Supplement, will be payable on March 1 and September 1 of each year
(each an "Interest Payment Date") and at maturity or upon redemption. If any
Interest Payment Date (including the date of maturity or any earlier redemption
date) for any Note would fall on a day which is not a Business Day, interest
payments will be postponed to the next day that is a Business Day, and no
interest will accrue for the period from and after the Interest Payment Date.
 
     Interest will be payable to the persons in whose names the Notes are
registered in the Debt Security register at the close of business on the date 15
calendar days prior to the Interest Payment Date (whether or not a Business
Day) (each such date, a "Regular Record Date"); provided, however, that
interest payable at maturity or upon redemption will be payable to the person 
to whom principal shall be payable. Notwithstanding the foregoing, the first 
payment of interest on any Note originally issued between a Regular Record 
Date and the next succeeding Interest Payment Date will be made on the 
Interest Payment Date following the next succeeding Regular Record Date to the
registered holder on such next succeeding Regular Record Date.
 
     Final Treasury Regulations respecting original issue discount were released
by the Internal Revenue Service on January 27, 1994, and if any Notes are issued
at an original issue discount for federal income tax purposes, the related
Pricing Supplement will set forth special federal income tax considerations
applicable thereto.
 
     Effective January 1, 1993, the rate of backup withholding tax referred to
in the penultimate paragraph under "Certain Federal Income Tax Consequences" in
the Prospectus was raised from 20 percent to 31 percent.
 
     Interest payments will include accrued interest from the date of issue or
from the last date in respect of which interest has been paid, as the case may
be, to, but excluding, the Interest Payment Date.
 
     Interest rates on Notes offered for sale are subject to change without
notice by the Company from time to time, but no such change will affect any Note
theretofore issued or as to which an offer to purchase has been accepted by the
Company.
 
REDEMPTION
 
     Unless otherwise specified in the applicable Pricing Supplement, the Notes
will not be redeemable prior to their maturity. If so specified in the
applicable Pricing Supplement with respect to a Note, such Note will be
redeemable on or after the date set forth in such Pricing Supplement, either in
whole or from time to time in part, at the option of the Company, at the
redemption price set forth in such Pricing Supplement, together with interest
accrued thereon to the date of redemption, on notice given not more than 60 nor
less than 30 days prior to the date of redemption.
 
REPURCHASE
 
     The Company may at any time 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 Trustee for cancellation.
 
DEFEASANCE
 
     The Notes will be subject to defeasance as described under "Description of
the Debt Securities -- Defeasance" in the accompanying Prospectus.

PAYMENTS
 
     Payments of principal, premium, if any, and interest due with respect to
any Certificated Note at maturity or upon redemption will be made in immediately
available funds upon surrender of the Note at the office of the Paying Agent in
New York, New York, 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. Interest payable with respect to a Certificated Note
(other than interest payable at maturity or upon redemption) will be paid by
check mailed to the address of the registered holder as of the original issue
date or the Regular Record Date, as the case may be. Notwithstanding the
foregoing, a registered holder of $5,000,000 or more in aggregate principal
amount of Certificated Notes having the same Interest Payment Date will, upon
written request to the Paying Agent not later than 15 days prior to the Interest
Payment Date, be entitled to receive payments of interest thereon (other than at
maturity or upon redemption) by wire transfer of immediately available funds to
an account maintained by such registered holder with a bank located in the
United States.
 
     The total amount of any principal, premium, if any, and interest due on any
Global Security representing one or more Book-Entry Notes on any Interest
Payment Date or at maturity or redemption will be made available to the Paying
Agent on such date; provided, however, if such date falls on a day which is not
a Business Day, such amount will be made available on the next Business Day. As
soon as possible thereafter, the Paying Agent will make such payments to the
Depository. The Depository will allocate such payments to each Book-Entry Note
represented by such Global Security and will make payments to the owners or
holders thereof in accordance with its existing operating procedures. See
"Book-Entry System."
 
BOOK-ENTRY SYSTEM
 
     Upon issuance, all Book-Entry Notes aggregating up to $200 million
principal amount and having the same original issuance date, interest rate,
maturity and redemption provisions, if any, will be represented by a single
Global Security. Each Global Security representing one or more Book-Entry Notes
will be deposited with, or on behalf of, the Depository, and registered in the
name of a nominee of the Depository. Upon the issuance of a Global Security, the
Depository will credit, on its book-entry registration and transfer system, the
principal amounts of the Book-Entry Notes represented by such Global Security to
the accounts of those institutions that have accounts with the Depository and
have purchased such Book-Entry Notes ("Participants"). The accounts to be
credited shall be designated by the Agents, if such Book-Entry Notes are sold by
them, or by the Company, if such Book-Entry Notes are sold directly by the
Company. Ownership of beneficial interests in such Global Securities will be
limited to Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Securities will be shown on,
and the transfer of that ownership will be effected only through, records
maintained by the Depository or its nominee for such Global Security (with
respect to Participants' interests) or by Participants (with respect to persons
that hold through Participants). The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such laws may impair the ability to transfer beneficial
interests in Global Securities.
 
     So long as the Depository, or its nominee, is the registered holder of a
Global Security, the Depository or such nominee, as the case may be, will be
considered the sole owner or registered holder of the Book-Entry Notes
represented by such Global Security for all purposes under the Indenture. Except
as set forth below, owners of beneficial interests in any such Global Security
will not be entitled to have Book-Entry Notes of the series represented by such
Global Security registered in their names, will not receive or be entitled to
receive physical delivery of Book-Entry Notes of such series in definitive form
and will not be considered the registered holders thereof under the Indenture.
For a description of certain of the rights of registered holders under the
Indenture, see "Description of the Debt Securities -- Events of Default" and
"-- Modification of the Indenture" in the accompanying Prospectus.

     Principal, premium, if any, and interest payments on Book-Entry Notes
registered in the name of the Depository or its nominee will be made to the
Depository or its nominee, as the case may be, as the registered holder of the
Global Security representing such Book-Entry Notes. None of the Company, the
Trustee, any paying agent or the registrar for such Book-Entry Notes will have
any responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests in a Global Security
for such Book-Entry Notes or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
     The Company expects that the Depository, upon receipt of any payment of
principal, premium or interest in respect of a Global Security, will credit
Participants' accounts immediately with amounts thereof proportionate to their
beneficial interests in the principal amount of such Global Security as shown on
the records of such Depository. The Company 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 registered in "street name", which payments will be the sole
responsibility of such Participants. The Company has, however, no control over
the practices of the Depository or the Participants and there can be no
assurance that these practices will not be changed.
 
     A Global Security may not be transferred except as a whole by the
Depository to a nominee of such Depository or by a nominee of such Depository to
such Depository or another nominee of such Depository or by such Depository or
any such nominee to a successor of such Depository or a nominee of such
successor. If the Depository is at any time unwilling or unable to continue as
Depository or if at any time the Depository ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and, in either event, the Company is unable to arrange for a qualified
successor, then the Company will issue Certificated Notes in definitive form in
exchange for the Global Security representing such Book-Entry Notes. In
addition, the Company may at any time and in its sole discretion determine not
to have any Book-Entry Notes represented by one or more Global Securities and,
in such event, will issue Certificated Notes in definitive form in exchange for
all Global Securities representing such Book-Entry Notes. Moreover, if there
shall have occurred and be continuing an Event of Default, or an event which,
with the giving of notice or lapse of time, or both, would constitute an Event
of Default with respect to any Book-Entry Notes represented by one or more
Global Securities, such Global Securities shall be exchangeable for Certificated
Notes in definitive form.
 
     The Depository has advised the Company and the Agents as follows: The
Depository is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Depository was created to hold securities of its Participants
and to facilitate the clearance and settlement of securities transactions among
its Participants in such securities through electronic book-entry changes in
accounts of the Participants, thereby eliminating the need for physical movement
of securities certificates. The Depository's Participants include securities
brokers and dealers (including the Agents), banks (including the Trustee), trust
companies, clearing corporations and certain other organizations, some of whom
(or their representatives) own the Depository. Access to the Depository's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly.

                              PLAN OF DISTRIBUTION
 
     Under the terms of a Distribution Agreement between the Agents and the
Company, dated September 24, 1991, 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 the Notes. The Company also may sell
Notes to any of the Agents or any other person, as principal, for resale by such
Agent or person at varying prices as will be determined by such Agent or person
at the time of such resale, which prices may be higher or lower than the price
to the public set forth herein. Unless otherwise agreed by the Company and the
Agents, the Company will have the sole right to accept offers to purchase Notes
and may reject any proposed purchase of Notes in whole or in part. Each Agent
will have the right, in its reasonable discretion, to reject any offer to
purchase Notes received by it, in whole or in part. The Company will pay each
Agent a commission, in connection with sales of Notes to purchasers solicited by
such Agent, not to exceed .600% of the purchase price of Notes so sold,
depending upon the maturity of the Notes. The Company reserves the right to sell
Notes from time to time directly on its own behalf to investors or through other
agents, dealers or underwriters; if the Company grants any discount or pays any
commission to such persons, such discount or commission will be disclosed in the
applicable Pricing Supplement. No commission will be payable on any Notes sold
directly by the Company.
 
     Unless otherwise specified in the applicable Pricing Supplement, payment of
the purchase price of Notes acquired through an Agent acting as agent is
required to be made in immediately available funds in New York, New York.
 
     Any Agent, when acting as agent or principal, may be deemed to be an
"underwriter" within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"), in respect of the Notes. The Company has agreed to indemnify
each Agent against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments such Agent may be required to make
in respect thereof. The Company has agreed to reimburse the Agents for certain
expenses, including fees and disbursements of counsel to the Agents.
 
     The Company has been advised by the Agents that they may from time to time
make a market in the Notes, but they are not obligated to do so and may
discontinue such market-making at any time without notice. Further, the Agents
may from time to time purchase and sell Notes in the secondary market, but they
are not obligated to do so. No assurance can be given as to the liquidity of any
trading market for the Notes.
 
     In addition to offering Notes as described herein, the Company may also
sell other Debt Securities pursuant to any other prospectus supplement. Any
sales of such other Debt Securities pursuant to another prospectus supplement
may reduce the principal amount of Notes which may be offered by this Prospectus
Supplement and the Prospectus.
 
     Certain of the Agents and their affiliates have from time to time provided
investment banking and commercial banking services to the Company for which
services such Agents and their affiliates have received customary fees and
commissions.
