                            ------------------------
 
     National Rural Utilities Cooperative Finance Corporation ("CFC" or the
"Company") may offer from time to time its Medium-Term Notes, Series C (the
"Notes") for proceeds up to U.S. $448,240,000 (or the equivalent thereof if any
of the Notes are denominated in foreign currencies or currency units), subject
to reduction as a result of the sale of its Euro Medium-Term Notes outside the
United States. See "Description of the Medium-Term Notes--General" and "Plan of
Distribution". Each Note will mature on a date nine months or more from the date
of issue, as set forth on the face of such Note. The Notes denominated in U.S.
dollars will be issued in denominations of $1,000 and any integral multiple
thereof. If the Notes are to be denominated in a foreign currency or currency
unit (a "Specified Currency"), then the provisions with respect thereto will be
set forth in an accompanying Prospectus Supplement (a "Supplement") to this
Prospectus Supplement. See "Description of the Medium-Term Notes".
 
     The Notes will be issued only in fully registered form and will be
represented by either a global security registered in the name of a nominee of
The Depository Trust Company, as Depositary (a "Book-Entry Note"), or a
certificate issued in definitive form (a "Certificated Note"), as set forth in
the applicable Supplement. Beneficial interests in Book-Entry Notes will be
shown on and transfer thereof will be effected only through the records
maintained by the Depositary's participants. See "Description of the Medium-Term
Notes--Book-Entry Notes". Except as described in "Description of the Medium-Term
Notes--Book-Entry Notes", owners of beneficial interest in Book-Entry Notes will
not be entitled to receive Certificated Notes and will not be considered the
holders of such Book-Entry Notes.
 
     The interest rate, issue price and stated maturity for each Note and
whether such Note is a Book-Entry Note or a Certificated Note will be
established by the Company at the date of issuance of such Note and will be
indicated in the applicable Supplement. Interest rates are subject to change by
the Company, but no such change will affect the interest rate on any Note
theretofore issued or which the Company has agreed to sell. Unless otherwise
indicated in the applicable Supplement, the Notes will bear interest at a fixed
rate. See "Description of the Medium-Term Notes".
 
     Unless otherwise indicated in the applicable Supplement, the Interest
Payment Dates for Notes will be January 15 and July 15 of each year.
 
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
             ACCOMPANYING PROSPECTUS. ANY REPRESENTATION TO THE
                CONTRARY IS A CRIMINAL OFFENSE.

                      DESCRIPTION OF THE MEDIUM-TERM 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 of the Securities set forth under the heading
"Description of Securities" in the accompanying Prospectus, to which description
reference is made. The Notes are referred to in the Prospectus as the "Offered
Securities". Unless otherwise specified in an applicable Supplement, the
following description of the Notes will apply.
 
GENERAL
 
     The Notes will be issued under the Indenture referred to in the
accompanying Prospectus, as supplemented by a First Supplemental Indenture dated
as of October 1, 1990 (the "Indenture"), with Harris Trust and Savings Bank, as
successor trustee (the "Trustee"). The Company has initially designated Bank of
Montreal Trust Company as its Paying Agent and Security Registrar for the Notes.
 
     The Notes offered hereby constitute a single series for purposes of the
Indenture, unlimited in aggregate principal amount. See "Plan of Distribution".
Unless otherwise indicated in the applicable Supplement, currency amounts in
this Prospectus Supplement, the accompanying Prospectus and any Supplement are
stated in United States dollars ("$", "dollars", "U.S. dollars" or "U.S. $").
 
     Each Note will mature nine months or more from the date of issue, as
selected by the initial purchaser and agreed to by the Company and as specified
in the applicable Supplement.
 
     The Notes will be issuable only in fully registered form, and if
denominated in U.S. dollars, in denominations of $1,000 and integral multiples
of $1,000 in excess thereof. The authorized denominations of Notes not
denominated in U.S. dollars will be set forth in the applicable Supplement.
 
     The Supplement relating to a Note will describe the following terms: (1)
the Specified Currency of such Note; (2) if other than 100%, the price
(expressed as a percentage of the aggregate principal amount thereof) at which
such Note will be issued; (3) the date on which such Note will be issued; (4)
the date on which such Note will mature (the "Maturity Date"); (5) the rate per
annum at which such Note will bear interest; (6) whether such Note will be
issued initially as a Book-Entry Note or a Certificated Note; and (7) any other
terms of such Note not inconsistent with the provisions of the Indenture.
 
     Each Note will be issued initially as either a Book-Entry Note or a
Certificated Note. The depositary for the Book-Entry Notes will initially be The
Depository Trust Company in The City of New York (the "Depositary"). See
"Book-Entry Notes".
 
     An Original Issue Discount Note is a Note which is issued at a price lower
than the principal amount thereof and which provides that upon redemption or
acceleration of the maturity thereof an amount less than the principal thereof
shall become due and payable. In the event of redemption or acceleration of the
maturity of an Original Issue Discount Note, the amount payable to the Holder of
such Note upon such redemption or acceleration will be determined in accordance
with the terms of the Note. For information respecting "original issue discount"
for United States federal income tax purposes, see "United States Taxation--U.S.
Holders-- Original Issue Discount" in the Prospectus.
 
     Unless otherwise indicated in the applicable Supplement, the Notes will be
denominated in U.S. dollars and payments of principal of, premium, if any, and
any interest on the Notes will be made in U.S. dollars. If any of the Notes are
to be denominated in a foreign currency (a currency other than U.S. dollars) or
currency unit, or if the principal of, premium, if any, and any interest on any
of the Notes is to be payable at the option of the Holder or the Company in a
currency, including a currency unit, other than that in which such Note is
denominated, the applicable Supplement will provide additional information,
including applicable exchange rate information, pertaining to the terms of such
Notes and other matters of interest to the Holders thereof.
 
     Payments on Book-Entry Notes will be made through the Paying Agent to the
Depositary. See "Book-Entry Notes".
 
     Payments of principal of, premium, if any, and any interest on any
Certificated Note payable at maturity or upon redemption will be made in
immediately available funds at the office of the Paying Agent in the Borough of
Manhattan, The City of New York, provided that payments in such funds will be
made only if such Notes are
 
                                       S-2
<PAGE>   3
 
presented to the Paying Agent in time for the Paying Agent to make such payments
in such funds in accordance with its normal procedures. The Company has
initially designated Bank of Montreal Trust Company, acting through its office
in the Borough of Manhattan, The City of New York, as its Paying Agent for the
Notes. Interest on Certificated Notes (other than interest payable at maturity
or upon redemption) will be paid by check mailed to the address of the person
entitled thereto. Notwithstanding the foregoing, a Holder of $10,000,000 or more
in aggregate principal amount of Certificated Notes of like tenor and terms will
be entitled to receive such payment of interest 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 Regular Record Date
for such payment of interest.
 
     Certificated Notes may be presented for registration of transfer or
exchange at the office of Bank of Montreal Trust Company in the Borough of
Manhattan, The City of New York. Book-Entry Notes may be transferred or
exchanged through a participating member of the Depositary. See "Book-Entry
Notes".
 
     The Notes will be direct, unsecured obligations of the Company.
 
     For a description of the rights attaching to different series of Securities
under the Indenture, see "Description of Securities" in the Prospectus.
 
INTEREST AND INTEREST RATES
 
     Each Note will bear interest from the date of issue or from the most recent
Interest Payment Date to which interest on such Note has been paid or duly
provided for at the fixed rate per annum stated therein and in the applicable
Supplement until the principal thereof is paid or made available for payment.
Interest will be payable on each Interest Payment Date and at maturity or upon
earlier redemption or repayment, if applicable (each such date a "Maturity").
See "Description of Securities--Payment and Paying Agents" in the Prospectus.
Interest will be payable to the Person in whose name a Note is registered at the
close of business on the Regular Record Date next preceding each Interest
Payment Date; provided, however, that interest payable at Maturity will be
payable to the Person to whom principal shall be payable. Unless otherwise
indicated in the applicable Supplement, the first payment of interest on any
Note originally issued between a Regular Record Date and an 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.
 
     Interest rates are subject to change by the Company from time to time, but
no such change will affect any Note already issued or as to which an offer to
purchase has been accepted by the Company.
 
     Unless otherwise indicated in the applicable Supplement, the Interest
Payment Dates for the Notes will be January 15 and July 15 of each year and the
Regular Record Dates will be January 1 and July 1 of each year. Interest on
Notes will be computed and paid on the basis of a 360-day year of twelve 30-day
months. Interest payments on Notes will equal the amount of interest accrued
from and including the next preceding Interest Payment Date in respect of which
interest has been paid (or from and including the date of issue, if no interest
has been paid with respect to such Notes), to but excluding the related Interest
Payment Date or Maturity, as the case may be. If any Interest Payment Date or
the Maturity of a Note falls on a day that is not a Business Day, the related
payment of principal, premium, if any, or interest will be made on the next
succeeding Business Day as if made on the date such payment was due, and no
interest will accrue on the amount so payable for the period from and after such
Interest Payment Date or Maturity, as the case may be.
 
BOOK-ENTRY NOTES
 
     The Depositary will act as securities depositary for Book-Entry Notes. The
Book-Entry Notes will be issued as fully-registered securities registered in the
name of Cede & Co. (the Depositary's partnership nominee). One fully-registered
Global Security will be issued for each issue of the Notes, each in the
aggregate principal amount of such issue, and will be deposited with the
Depositary. If, however, the aggregate principal amount of any issue exceeds
$200 million, one Global Security will be issued with respect to each $200
million of principal amount and an additional Global Security will be issued
with respect to any remaining principal amount of such issue.
 
                                       S-3
<PAGE>   4
 
     The Depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934, as amended. The Depositary holds securities that its
participants ("Participants") deposit with the Depositary. The Depositary also
facilitates the settlement among Participants of securities transactions, such
as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct participants
("Direct Participants") include securities brokers and dealers, banks, trust
companies, clearing corporations, and certain other organizations. The
Depositary is owned by a number of its Direct Participants and by the New York
Stock Exchange, Inc., the American Stock Exchange, Inc., and the NASD. Access to
the Depositary's system is also available to others such as securities brokers
and dealers, banks and trust companies that clear through or maintain a
custodial relationship with a Direct Participant, either directly or indirectly
("Indirect Participants"). The rules applicable to the Depositary and its
Participants are on file with the Securities and Exchange Commission.
 
     Purchases of Book-Entry Notes under the Depositary's system must be made by
or through Direct Participants, which will receive a credit for the Book-Entry
Notes on the Depositary's records. The ownership interest of each actual
purchaser of each Book-Entry Note ("Beneficial Owner") is in turn to be recorded
on the Direct and Indirect Participants' records. Beneficial Owners will not
receive written confirmation from the Depositary of their purchase, but
Beneficial Owners are expected to receive written confirmations providing
details of the transaction, as well as periodic statements of their holdings,
from the Direct or Indirect Participant through which the Beneficial Owner
entered into the transaction. Transfers of ownership interests in the Book-Entry
Notes are to be accomplished by entries made on the books of Participants acting
on behalf of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interests in Book-Entry Notes, except in the event
that use of the book-entry system for one or more Book-Entry Notes is
discontinued.
 
     To facilitate subsequent transfers, all Global Securities deposited by
Participants with the Depositary are registered in the name of the Depositary's
partnership nominee, Cede & Co. The deposit of Global Securities with the
Depositary and their registration in the name of Cede & Co. effects no change in
beneficial ownership. The Depositary has no knowledge of the actual Beneficial
Owners of the Book-Entry Notes; the Depositary's records reflect only the
identity of the Direct Participants to whose accounts such Book-Entry Notes are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.
 
     Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices will be sent to Cede & Co. If less than all of the
Book-entry Notes are being redeemed, and unless otherwise notified by either the
Company or the Trustee, the Depositary's practice is to determine by lot the
amount of the interest of each Direct Participant in such issue to be redeemed.
 
     Neither the Depositary nor Cede & Co. will consent or vote with respect to
Book-Entry Notes. Under its usual procedures, the Depositary will mail an
Omnibus Proxy to the Company as soon as possible after the record date. The
Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Book-Entry Notes are credited on the record
date (identified in a listing attached to the Omnibus Proxy).
 
     Principal and interest payments on the Book-Entry Notes will be made to the
Depositary. The Depositary's practice is to credit Direct Participants' accounts
on the payable date in accordance with their respective holdings shown on the
Depositary's records unless the Depositary has reason to believe that it will
not receive payment on the payable date. Payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name" and will be the responsibility of such Participant
and not of the Depositary, any Agents, or the
 
                                       S-4
<PAGE>   5
 
Company, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of principal and interest to the Depositary is the
responsibility of the Company or Agents, disbursement of such payments to Direct
Participants will be the responsibility of the Depositary, and disbursement of
such payments to the Beneficial Owners will be the responsibility of Direct and
Indirect Participants.
 
     A Beneficial Owner must give notice to elect to have its Book-Entry Notes
purchased or tendered, through its Participant, to the Paying Agent, and must
effect delivery of such Book-Entry Notes by causing the Direct Participant to
transfer the Participant's interest in the Book-Entry Notes, on the Depositary's
records, to the Paying Agent. The requirement for physical delivery of
Book-Entry Notes in connection with a demand for purchase or a mandatory
purchase will be deemed satisfied when the ownership rights in the Book-Entry
Notes are transferred by Direct Participants on the Depositary's records.
 
     The Depositary may discontinue providing its services as securities
depositary with respect to the Book-Entry Notes at any time by giving reasonable
notice to the Company or the Agents. Under such circumstances, in the event that
a successor securities depositary is not obtained, Certificated Notes are
required to be printed and delivered in exchange for the Book-Entry Notes
represented by the Global Securities held by the Depositary.
 
     The Company may decide to discontinue use of system of book-entry transfers
through the Depositary (or a successor securities depositary). In that event,
Certificated Notes will be printed and delivered in exchange for the Book-Entry
Notes represented by the Global Securities held by the Depositary.
 
     The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that the Company
believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.
 
     Neither the Company, the Trustee, any paying agent nor the registrar for
the Notes will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interest
in a Global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.
 
                              PLAN OF DISTRIBUTION
 
     The Notes are offered on a continuing basis by the Company on its own
behalf directly to its members. The Company will have the sole right to accept
offers to purchase Notes and may reject any such offer, in whole or in part.
 
     The Company will provide separate instructions respecting procedures for
the purchase of Notes in its brochure entitled "CFC Medium-Term Notes". Unless
otherwise indicated in the applicable Supplement, payment of the purchase price
of Notes will be required to be made in immediately available funds to the
Trustee in New York City.
 
     In addition to the offering of the Notes directly by the Company as
described herein, the Notes are being offered on a continuing basis by the
Company through Lehman Brothers, Lehman Brothers Inc. (including its affiliate
Lehman Government Securities Inc.) and Merrill Lynch & Co., Merrill Lynch,
Pierce, Fenner & Smith Incorporated (the "Agents"), which have agreed to use
their best efforts to solicit purchases of the Notes under the terms of an
Agency Agreement dated April 13, 1995 (the "Agency Agreement"). The Company will
pay each Agent a commission of from .125% to .625% of the principal amount of
each Note, depending on its Stated Maturity, sold through such Agent.
 
     The Company also may sell Notes to each Agent, acting as principal, at or
above par or at a discount to be agreed upon at the time of sale, for resale to
one or more investors at varying prices related to prevailing market prices at
the time of such resale, as determined by such Agent. The Company has reserved
the right to sell Notes directly on its own behalf other than to its members.
 
     Any Notes sold pursuant to the Agency Agreement, or sold by the Company to
the Agents for resale as contemplated by the Agency Agreement, will reduce the
remaining principal amount of Notes which may be offered by this Prospectus
Supplement and the Prospectus.
 
                                       S-5
<PAGE>   6
 
     In addition to offering Notes as described herein, Securities which are
medium-term notes and may have terms substantially similar to the terms of the
Notes offered hereby (but constituting one or more separate series of the
Securities for purposes of the Indenture) may be offered in the future on a
continuing basis primarily in Europe ("Euro Medium-Term Notes") by the Company
pursuant to a Placement Agency Agreement with Lehman Brothers International,
Inc., Union Bank of Switzerland (Securities) Limited and such other firms as may
be named (the "European Agents") as agents for the Company, the terms of which
are expected to be substantially similar to the terms of the Agency Agreement,
except for certain selling restrictions specified in the Placement Agency
Agreement. Any Securities sold pursuant to such Placement Agency Agreement, or
sold by the Company to the European Agents for resale as contemplated by such
Placement Agency Agreement, will reduce the remaining principal amount of Notes
which may be offered by this Prospectus Supplement and the Prospectus.

                          MEDIUM-TERM NOTES, SERIES C
           WITH MATURITIES OF NINE MONTHS OR MORE FROM DATE OF ISSUE
                            ------------------------
 
     National Rural Utilities Cooperative Finance Corporation ("CFC" or the
"Company") may offer from time to time its Medium-Term Notes, Series C (the
"Notes") for proceeds up to U.S. $448,240,000 (or the equivalent thereof if any
of the Notes are denominated in foreign currencies or currency units), subject
to reduction as a result of the sale of its Euro Medium-Term Notes outside the
United States. See "Description of the Medium-Term Notes--General" and "Plan of
Distribution". Each Note will mature on a date nine months or more from the date
of issue, as set forth on the face of such Note. If set forth in an accompanying
Prospectus Supplement (a "Supplement") to this Prospectus Supplement, the Notes
will be redeemable at the option of the Company or repayable at the option of
the holder prior to their stated maturity. The Notes denominated in U.S. dollars
will be issued in denominations of $1,000 and any integral multiple thereof. If
the Notes are to be denominated in a foreign currency or currency unit (a
"Specified Currency"), then the provisions with respect thereto will be set
forth in the applicable Supplement. See "Description of the Medium-Term Notes".
 
     The Notes will be issued only in fully registered form and will be
represented by either a global security registered in the name of a nominee of
The Depository Trust Company, as Depositary (a "Book-Entry Note"), or a
certificate issued in definitive form (a "Certificated Note"), as set forth in
the applicable Supplement. Beneficial interests in Book-Entry Notes will be
shown on and transfer thereof will be effected only through the records
maintained by the Depositary's participants. See "Description of the Medium-Term
Notes--Book-Entry Notes". Except as described in "Description of the Medium-Term
Notes--Book-Entry Notes", owners of beneficial interest in Book-Entry Notes will
not be entitled to receive Certificated Notes and will not be considered the
holders of such Book-Entry Notes.
 
     The interest rate or interest rate formula, issue price and stated maturity
for each Note and whether such Note is a Book-Entry Note or a Certificated Note
will be established by the Company at the date of issuance of such Note and will
be indicated in the applicable Supplement. Interest rates and interest rate
formulas are subject to change by the Company, but no such change will affect
the interest rate on, or interest rate formula for, any Note theretofore issued
or which the Company has agreed to sell. Unless otherwise indicated in the
applicable Supplement, the Notes will bear interest at a fixed rate (a "Fixed
Rate Note") or at a rate or rates determined by reference to LIBOR, the Treasury
Rate, the Commercial Paper Rate, the Prime Rate, the Fed Funds Rate, the CD Rate
or such other interest rate formula as may be designated in the applicable
Supplement (a "Base Rate"), as adjusted by a Spread and/or Spread Multiplier, if
any, applicable to such Notes (a "Floating Rate Note"). See "Description of the
Medium-Term Notes".
 
     Unless otherwise indicated in the applicable Supplement, the Interest
Payment Dates for Fixed Rate Notes will be January 15 and July 15 of each year
and for Floating Rate Notes will be as specified under "Description of the
Medium-Term Notes--Floating Rate Notes".

  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,

(1) Unless otherwise specified in a Supplement, Notes will be issued at 100% of
    principal amount.
(2) The Company will pay to each Agent referred to below a commission, in the
    form of a discount, ranging from .125% to .625% of the principal amount of
    any Note, depending upon its stated maturity, sold through such Agent.
    Commissions with respect to Notes with stated maturities in excess of 30
    years that are sold through an Agent will be negotiated between the Company
    and such Agent at the time of such sale. Either Agent, acting as principal,
    may also purchase Notes at a discount for resale to investors or other
    purchasers at varying prices related to prevailing market prices at the time
    of resale as determined by the applicable Agent or, if so agreed, at a fixed
    public offering price. Unless otherwise specified in the applicable
    Supplement, any Note sold to an Agent as principal will be purchased by such
    Agent at a price equal to 100% of the principal amount thereof less a
    percentage equal to the commission applicable to an agency sale of a Note of
    identical maturity. No commission will be payable on any Note sold directly
    by the Company. The Company has agreed to indemnify the Agents against
    certain liabilities, including liabilities under the Securities Act of 1933.
(3) Assuming Notes are issued at 100% of principal amount and before deducting
    expenses payable by the Company estimated at U.S. $390,000.
(4) In U.S. dollars or the equivalent thereof in foreign currencies or currency
    units.

    Distribution".
                            ------------------------
 
     The Notes are being offered on a continuing basis by the Company through
Lehman Brothers, Lehman Brothers Inc. (including its affiliate Lehman Government
Securities Inc.), and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated (the "Agents"), which have agreed to use their best efforts to
solicit offers to purchase the Notes. The Notes may be sold at or above par or
at a discount to an Agent as principal for resale to investors at varying prices
related to prevailing market prices at the time of resale as determined by such
Agent or, if so agreed, at a fixed public offering price. The Company has
reserved the right to sell Notes directly on its own behalf. The Notes will not
be listed on any securities exchange, and there can be no assurance that the
Notes will be sold or that there will be a secondary market for the Notes. The
Company reserves the right to withdraw, cancel or modify the offer or
solicitation of offers made hereby without notice. The Company, or the
soliciting Agent, may reject any offer in whole or in part. See "Plan of
Distribution".

                      DESCRIPTION OF THE MEDIUM-TERM 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 of the Securities set forth under the heading
"Description of Securities" in the accompanying Prospectus, to which description
reference is made. The Notes are referred to in the Prospectus as the "Offered
Securities". Unless otherwise specified in an applicable Supplement, the
following description of the Notes will apply.
 
GENERAL
 
     The Notes will be issued under the Indenture referred to in the
accompanying Prospectus, as supplemented by a First Supplemental Indenture dated
as of October 1, 1990 (the "Indenture"), with Harris Trust and Savings Bank, as
successor trustee (the "Trustee"). The Company has initially designated Bank of
Montreal Trust Company as its Paying Agent and Security Registrar for the Notes.
 
     The Notes offered hereby constitute a single series for purposes of the
Indenture, unlimited in aggregate principal amount. See "Plan of Distribution".
Unless otherwise indicated in the applicable Supplement, currency amounts in
this Prospectus Supplement, the accompanying Prospectus and any Supplement are
stated in United States dollars ("$", "dollars", "U.S. dollars" or "U.S. $").
 
     Each Note will mature nine months or more from the date of issue, as
selected by the initial purchaser and agreed to by the Company and as specified
in the applicable Supplement, and may be subject to redemption at the option of
the Company or repurchase at the option of the Holder prior to Stated Maturity
as set forth below under "Redemption and Repayment".
 
     The Notes will be issuable only in fully registered form, and if
denominated in U.S. dollars, in denominations of $1,000 and integral multiples
of $1,000 in excess thereof. The authorized denominations of Notes not
denominated in U.S. dollars will be set forth in the applicable Supplement.
 
     The Supplement relating to a Note will describe the following terms: (1)
the Specified Currency of such Note; (2) whether such Note is a Fixed Rate Note
or a Floating Rate Note; (3) if other than 100%, the price (expressed as a
percentage of the aggregate principal amount thereof) at which such Note will be
issued; (4) the date on which such Note will be issued; (5) the date on which
such Note will mature (the "Maturity Date"); (6) if such Note is a Fixed Rate
Note, the rate per annum at which such Note will bear interest; (7) if such Note
is a Floating Rate Note, the Base Rate, the Initial Interest Rate, the Interest
Payment Dates, the Reset Period, the Index Maturity, the Maximum Interest Rate
and the Minimum Interest Rate, if any, and the Spread and/or Spread Multiplier,
if any (all as defined herein), and any other terms relating to the particular
method of calculating the interest rate or rates for such Note; (8) whether such
Note may be redeemed or repaid prior to maturity, and if so, the provisions
relating to such redemption or repayment; (9) whether such Note will be issued
initially as a Book-Entry Note or a Certificated Note; and (10) any other terms
of such Note not inconsistent with the provisions of the Indenture.
 
     Each Note will be issued initially as either a Book-Entry Note or a
Certificated Note. The depositary for the Book-Entry Notes will initially be The
Depository Trust Company in The City of New York (the "Depositary"). See
"Book-Entry Notes".
 
     An Original Issue Discount Note is a Note which is issued at a price lower
than the principal amount thereof and which provides that upon redemption or
acceleration of the maturity thereof an amount less than the principal thereof
shall become due and payable. In the event of redemption or acceleration of the
maturity of an Original Issue Discount Note, the amount payable to the Holder of
such Note upon such redemption or acceleration will be determined in accordance
with the terms of the Note. For information respecting "original
 
                                       S-2

issue discount" for United States federal income tax purposes, see "United
States Taxation--U.S. Holders-- Original Issue Discount" in the Prospectus.
 
     Unless otherwise indicated in the applicable Supplement, the Notes will be
denominated in U.S. dollars and payments of principal of, premium, if any, and
any interest on the Notes will be made in U.S. dollars. If any of the Notes are
to be denominated in a foreign currency (a currency other than U.S. dollars) or
currency unit, or if the principal of, premium, if any, and any interest on any
of the Notes is to be payable at the option of the Holder or the Company in a
currency, including a currency unit, other than that in which such Note is
denominated, the applicable Supplement will provide additional information,
including applicable exchange rate information, pertaining to the terms of such
Notes and other matters of interest to the Holders thereof.
 
     Payments on Book-Entry Notes will be made through the Paying Agent to the
Depositary. See "Book-Entry Notes".
 
     Payments of principal of, premium, if any, and any interest on any
Certificated Note payable at maturity or upon redemption will be made in
immediately available funds at the office of the Paying Agent in the Borough of
Manhattan, The City of New York, provided that payments in such funds will be
made only if such Notes are presented to the Paying Agent in time for the Paying
Agent to make such payments in such funds in accordance with its normal
procedures. The Company has initially designated Bank of Montreal Trust Company,
acting through its office in the Borough of Manhattan, The City of New York, as
its Paying Agent for the Notes. Interest on Certificated Notes (other than
interest payable at maturity or upon redemption) will be paid by check mailed to
the address of the person entitled thereto. Notwithstanding the foregoing, a
Holder of $10,000,000 or more in aggregate principal amount of Certificated
Notes of like tenor and terms will be entitled to receive such payment of
interest 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 Regular Record Date for such payment of interest.
 
     Certificated Notes may be presented for registration of transfer or
exchange at the office of Bank of Montreal Trust Company in the Borough of
Manhattan, The City of New York. Book-Entry Notes may be transferred or
exchanged through a participating member of the Depositary. See "Book-Entry
Notes".
 
     The Notes will be direct, unsecured obligations of the Company.
 
     For a description of the rights attaching to different series of Securities
under the Indenture, see "Description of Securities" in the Prospectus.
 
INTEREST AND INTEREST RATES
 
     Each Note will bear interest from the date of issue or from the most recent
Interest Payment Date to which interest on such Note has been paid or duly
provided for at the fixed rate per annum, or at the rate per annum determined
pursuant to the interest rate formula, stated therein and in the applicable
Supplement until the principal thereof is paid or made available for payment.
Interest will be payable on each Interest Payment Date and at maturity or upon
earlier redemption or repayment (each such date a "Maturity"). See "Description
of Securities--Payment and Paying Agents" in the Prospectus. Interest will be
payable to the Person in whose name a Note is registered at the close of
business on the Regular Record Date next preceding each Interest Payment Date;
provided, however, that interest payable at Maturity will be payable to the
Person to whom principal shall be payable. Unless otherwise indicated in the
applicable Supplement, the first payment of interest on any Note originally
issued between a Regular Record Date and an 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.
 
     Interest rates, or interest rate formulas, are subject to change by the
Company from time to time, but no such change will affect any Note already
issued or as to which an offer to purchase has been accepted by the Company.
Unless otherwise indicated in the applicable Supplement, the Interest Payment
Dates and the Regular Record Dates for Fixed Rate Notes will be as described
below under "Fixed Rate Notes". Unless otherwise specified in the applicable
Supplement, the Interest Payment Dates for Floating Rate Notes will be as
described below under "Floating Rate Notes" and each Regular Record Date for a
Floating Rate Note will be the fifteenth calendar day
 
                                       S-3
<PAGE>   11
 
(whether or not a Business Day) next preceding each Interest Payment Date. If an
Interest Payment Date with respect to any Floating Rate Note would otherwise
fall on a day that is not a Business Day with respect to such Note, such
Interest Payment Date will be postponed to the following day that is a Business
Day with respect to such Note, except that in the case of a LIBOR Note, if such
day falls in the next calendar month, such Interest Payment Date will be the
preceding day that is a Business Day with respect to such LIBOR Note. If the
Maturity of a Floating Rate Note falls on a day that is not a Business Day, the
payment of principal, premium, if any, and interest will be made on the next
succeeding Business Day as if made on the date such payment was due, and no
interest on such payment will accrue for the period from and after such
Maturity.
 
     Each Note will bear interest at either (a) a fixed rate or rates or (b) a
variable rate determined by reference to an interest rate formula, which may be
based upon an Index Maturity. "Index Maturity" means the period to maturity of
the instrument or obligation on which the interest rate formula is based, as
specified in the applicable Supplement. A Floating Rate Note may also have
either or both of the following: (a) a maximum numerical interest rate
limitation, or ceiling, on the rate of interest which may accrue during any
interest period; and (b) a minimum numerical interest rate limitation, or floor,
on the rate of interest which may accrue during any interest period.
 
FIXED RATE NOTES
 
     Each Fixed Rate Note will bear interest from its date of issue at the
annual rate stated on the face thereof (as specified in the applicable
Supplement). The Interest Payment Dates for the Fixed Rate Notes will be January
15 and July 15 of each year and the Regular Record Dates will be January 1 and
July 1 of each year. Interest on Fixed Rate Notes will be computed and paid on
the basis of a 360-day year of twelve 30-day months. Interest payments on Fixed
Rate Notes will equal the amount of interest accrued from and including the next
preceding Interest Payment Date in respect of which interest has been paid (or
from and including the date of issue, if no interest has been paid with respect
to such Fixed Rate Notes), to but excluding the related Interest Payment Date or
Maturity, as the case may be. If any Interest Payment Date or the Maturity of a
Fixed Rate Note falls on a day that is not a Business Day, the related payment
of principal, premium, if any, or interest will be made on the next succeeding
Business Day as if made on the date such payment was due, and no interest will
accrue on the amount so payable for the period from and after such Interest
Payment Date or Maturity, as the case may be.
 
FLOATING RATE NOTES
 
     The interest rate on each Floating Rate Note will equal the interest rate
calculated by reference to the specified interest rate formula (as specified in
the applicable Supplement) plus or minus the Spread, if any, and/or multiplied
by the Spread Multiplier, if any. The "Spread" is the number of basis points
specified in the applicable Supplement as being applicable to the interest rate
for such Note and the "Spread Multiplier" is the percentage specified in the
applicable Supplement as being applicable to the interest rate for such Note.
 
     The applicable Supplement relating to a Floating Rate Note will designate
one or more interest rate bases for such Floating Rate Note. Such basis or bases
will be determined by reference to: (a) the Commercial Paper Rate, in which case
such Note will be a Commercial Paper Rate Note, (b) the Prime Rate, in which
case such Note will be a Prime Rate Note, (c) LIBOR, in which case such Note
will be a LIBOR Note, (d) the Treasury Rate, in which case such Note will be a
Treasury Rate Note, (e) the Federal Funds Effective Rate, in which case such
Note will be a Fed Funds Note, (f) the CD Rate, in which case such Note will be
a CD Rate Note, or (g) such other interest rate basis or formula as is set forth
in such Supplement. The applicable Supplement for a Floating Rate Note also will
specify the Spread and/or Spread Multiplier, if any, and the maximum or minimum
interest rate limitation, if any, applicable to each Note. In addition, such
Supplement may define or particularize for each Note the following terms, if
applicable: Calculation Date, Initial Interest Rate, Interest Payment Dates,
Regular Record Dates, Index Maturity, Interest Determination Dates and Interest
Reset Dates with respect to such Note.
 
     The rate of interest on each Floating Rate Note will be reset daily,
weekly, monthly, quarterly, semi-annually or annually (each an "Interest Reset
Date"), as specified in the applicable Supplement. Unless otherwise specified in
the applicable Supplement, the Interest Reset Date will be, in the case of
Floating Rate Notes that reset daily, each Business Day; in the case of Floating
Rate Notes (other than Treasury Rate Notes) which reset
 
                                       S-4
<PAGE>   12
 
weekly, the Wednesday of each week; in the case of Treasury Rate Notes which
reset weekly, except as set forth in the next paragraph, the Tuesday of each
week; in the case of Floating Rate Notes which reset monthly, the third
Wednesday of each month; in the case of Floating Rate Notes which reset
quarterly, the third Wednesday of March, June, September and December; in the
case of Floating Rate Notes which reset semi-annually, the third Wednesday of
two months of each year, as specified in the applicable Supplement; and in the
case of Floating Rate Notes which reset annually, the third Wednesday of one
month of each year, as specified in the applicable 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 (as set forth in the applicable Supplement) and (b) unless
otherwise specified in an applicable Supplement, the interest rate in effect for
the ten calendar days immediately prior to Maturity, if applicable, will be that
in effect on the tenth calendar day preceding Maturity. If any Interest Reset
Date for any Floating Rate Note would otherwise be a day that is not a Business
Day for such Floating Rate Note, the Interest Reset Date for such Floating Rate
Note will be postponed to the next day that is a Business Day for such Floating
Rate Note, except that in the case of a LIBOR Note, if such Business Day is in
the next succeeding calendar month, such Interest Reset Date will be the
immediately preceding Business Day. "Business Day" means (a) with respect to any
Note, any day that is not a Saturday or Sunday and that, in The City of New
York, is not a day on which banking institutions generally are authorized or
obligated by or pursuant to law, regulation or executive order to close, and (b)
with respect to LIBOR Notes only, any such day on which dealings in deposits in
U.S. dollars are transacted in the London interbank market (a "London Business
Day").
 
     The date as of which the interest rate will be determined (the "Interest
Determination Date") pertaining to an Interest Reset Date for a Commercial Paper
Rate Note (the "Commercial Paper Interest Determination Date"), for a Prime Rate
Note (the "Prime Interest Determination Date"), for a Fed Funds Note (the "Fed
Funds Interest Determination Date") and for a CD Rate Note (the "CD Interest
Determination Date") will be the second Business Day preceding the Interest
Reset Date with respect to such Note. The Interest Determination Date pertaining
to an Interest Reset Date for a LIBOR Note (the "LIBOR Interest Determination
Date") will be the second London Business Day preceding such Interest Reset
Date. The Interest Determination Date pertaining to an Interest Reset Date for a
Treasury Rate Note (the "Treasury Interest Determination Date") will be the day
of the week in which such Interest Reset Date falls on which Treasury bills
would normally be auctioned. Treasury bills are usually sold at auction on
Monday of each week, unless that day is a legal holiday, in which case the
auction is usually held on the following Tuesday, except that such auction may
be held on the preceding Friday. If, as the 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 for Treasury bills falls on any
Interest Reset Date for a Treasury Rate Note, then such Interest Reset Date will
instead be the first Business Day immediately following such auction date.
 
     Notwithstanding the maximum interest rate which may be applicable to any
Floating Rate Note pursuant to its terms, assuming that a court would enforce
the provisions of the Notes and the Indenture specifying New York law as the
governing law, the interest rate on the Floating Rate Notes 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 application. Under present New York
law, subject to certain exceptions, the maximum rate of interest for any loan in
an amount less than $250,000 is 16% per annum, and for any loan in the amount of
$250,000 or more but less than $2,500,000 is 25% per annum on a simple interest
basis. The limit may not apply to Floating Rate Notes in which $2,500,000 or
more has been invested.
 
     Unless otherwise indicated in the applicable Supplement and except as
provided below, interest will be payable, in the case of Floating Rate Notes
which reset daily, weekly or monthly, on the third Wednesday of each month or on
the third Wednesday of March, June, September and December of each year (as
indicated in the applicable Supplement); in the case of Floating Rate Notes
which reset quarterly, on the third Wednesday of March, June, September and
December of each year; in the case of Floating Rate Notes which reset
semi-annually, on the third Wednesday of the two months of each year specified
in the applicable Supplement; and in the case of Floating Rate Notes which reset
annually, on the third Wednesday of the month specified in the applicable
Supplement (each an "Interest Payment Date"), and in each case, at Maturity.
 
                                       S-5
<PAGE>   13
 
     Unless otherwise indicated in the applicable Supplement, interest payments
for Floating Rate Notes will be the amount of interest accrued from and
including the most recent date in respect of which interest has been paid or
duly provided for, or from and including the date of issue, to, but excluding,
the Interest Payment Date or Maturity date; provided, however, that if the
Interest Reset Dates with respect to any Floating Rate Note are daily or weekly,
interest payable on any Interest Payment Date, other than interest payable on
any date on which principal on any such Note is payable, will include interest
accrued from but excluding the most recent Regular Record Date in respect of
which interest has been paid or duly provided for, or from and including the
date of issue, to and including the next preceding Regular Record Date,
provided, however, that interest payments on Floating Rate Notes made at
Maturity will include interest accrued to but excluding the date of Maturity.
Accrued interest from the date of issue or from the last date to which interest
has been paid is calculated by multiplying the face amount of a Floating Rate
Note by an accrued interest factor. Such accrued interest factor is computed by
adding the interest factors calculated for each day in the period for which
accrued interest is being calculated. The interest factor for each such day is
computed by dividing the interest rate applicable to such date by 360, in the
case of Commercial Paper Rate Notes, Prime Rate Notes, LIBOR Notes, Fed Funds
Notes or CD Rate Notes, or by the actual number of days in the year, in the case
of Treasury 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 which will become effective as a result of a determination made on
the most recent Interest Determination Date with respect to such Floating Rate
Note. Unless otherwise provided in the applicable Supplement, Lehman Brothers
Inc., will be the calculation agent (the "Calculation Agent") with respect to
the Floating Rate Notes. Unless otherwise specified in the applicable Pricing
Supplement, the "Calculation Date," if applicable, pertaining to any Interest
Determination Date will be the earlier of (i) the tenth calendar day after such
Interest Determination Date, or, if such day is not a Business Day, the next
succeeding Business Day or (ii) the Business Day preceding the applicable
Interest Payment Date or Maturity, as the case may be.
 
     All percentages resulting from any calculation on Floating Rate Notes will
be rounded to the nearest one hundred-thousandth of a percentage point, with
five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or
.09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts
used in or resulting from such calculation on Floating Rate Notes will be
rounded to the nearest cent or, in the case of Notes denominated other than in
United States dollars, the nearest unit (with one-half cent or unit being
rounded upward).
 
  Commercial Paper Rate
 
     Unless otherwise indicated in the applicable Supplement, "Commercial Paper
Rate" means, with respect to any Commercial Paper Interest Determination Date,
the Money Market Yield (as defined below) of the rate on such date for
commercial paper having the Index Maturity designated in the applicable
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 selected by the Calculation Agent 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 9:00 a.m., New York City time, on
the Calculation Date pertaining to such Commercial Paper Interest Determination
Date, then the Commercial Paper Rate will be the Money Market Yield of the rate
on such Commercial Paper Interest Determination Date for commercial paper having
the Index Maturity designated in the applicable Supplement as published by the
Federal Reserve Bank of New York in its daily statistical release "Composite
3:30 p.m. Quotations for U.S. Government Securities" or any successor
publication selected by the Calculation Agent ("Composite Quotations") under the
heading "Commercial Paper". If such rate is not yet published by 3:00 p.m., New
York City time, on the Calculation Date pertaining to such Commercial Paper
Interest Determination Date, then the Commercial Paper Rate for such Commercial
Paper Interest Determination Date will be calculated by the Calculation Agent
and will be the Money Market Yield of the arithmetic mean of the offered rates
as of 11:00 A.M., New York City time, on such Commercial Paper Interest
Determination Date of three leading dealers of commercial paper in New York City
selected by the Calculation Agent for commercial paper having the Index Maturity
designated in the applicable Supplement placed for an industrial issuer whose
bond rating is "AA", or the equivalent, from a nationally recognized rating
agency; provided, however, that if the
 
                                       S-6
<PAGE>   14
 
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 then in effect on such Commercial Paper Interest Determination Date.
 
     "Money Market Yield" means a yield (expressed as a percentage rounded, if
necessary, to the next higher one hundred thousandth of a percentage point)
calculated in accordance with the following formula:
 
<TABLE>
<C>                    <C>               <S>
                            D X 360
  Money Market Yield = ----------------- X 100
                         360 - (D X M)
</TABLE>
 
where "D" refers to the per annum rate for the 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.
 
  LIBOR
 
     Unless otherwise indicated in the applicable Supplement, "LIBOR" will be
determined by the Calculation Agent in accordance with the following provisions:
 
          (i) With respect to a LIBOR Interest Determination Date, LIBOR will
     be, as specified in the applicable Supplement, either: (a) the arithmetic
     mean of the offered rates for deposits in U.S. dollars having the Index
     Maturity designated in the applicable Supplement, commencing on the second
     London Business Day immediately following such LIBOR Interest Determination
     Date, that appear on the Reuters Screen LIBO Page as of 11:00 A.M., London
     time, on such LIBOR Interest Determination Date, if at least two such
     offered rates appear on the Reuters Screen LIBO Page ("LIBOR Reuters"), or
     (b) the rate for deposits in U.S. dollars having the Index Maturity
     designated in the applicable Supplement, commencing on the second London
     Business Day immediately following such LIBOR Interest Determination Date,
     that appears on Telerate Page 3750 as of 11:00 A.M., London time, on such
     LIBOR Interest Determination Date ("LIBOR Telerate"). "Reuters Screen LIBO
     Page" means the display designated as page "LIBO" on the Reuters Monitor
     Money Rates Service (or such other page as may replace page LIBO on that
     service for the purpose of displaying London interbank offered rates of
     major banks). "Telerate Page 3750" means the display designated as page
     "3750" on the Telerate Service (or such other page as may replace the 3750
     page on that service or such other service or services as may be nominated
     by the British Bankers' Association for the purpose of displaying London
     interbank offered rates for U.S. dollar deposits). If neither LIBOR Reuters
     nor LIBOR Telerate is specified in the applicable Supplement, LIBOR will be
     determined as if LIBOR Telerate had been specified. If fewer than two
     offered rates appear on the Reuters Screen LIBO Page, or if no rate appears
     on Telerate Page 3750, as applicable, LIBOR in respect of such LIBOR
     Interest Determination date will be determined as if the parties had
     specified the rate described in (ii) below.
 
          (ii) With respect to a LIBOR Interest Determination Date on which
     fewer than two offered rates appear on the Reuters Screen LIBO Page, as
     specified in (i)(a) above, or on which no rate appears on Telerate Page
     3750, as specified in (i)(b) above, as applicable, LIBOR will be determined
     on the basis of the rates at which deposits in U.S. dollars having the
     Index Maturity designated in the applicable Supplement are offered at
     approximately 11:00 A.M., London time, on such LIBOR Interest Determination
     Date by four major banks in the London interbank market selected by the
     Calculation Agent (the "Reference Banks") to prime banks in the London
     interbank market, commencing on the second London Business Day immediately
     following such LIBOR Interest Determination Date and in a principal amount
     equal to the amount of not less than $1,000,000 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 the Reference Banks to
     provide a quotation of its rate. If at least two such quotations are
     provided, LIBOR in respect of such LIBOR Interest Determination Date will
     be the arithmetic mean of such quotations. If fewer than two quotations are
     provided, LIBOR in respect to such LIBOR Interest Determination Date will
     be the arithmetic mean of the rates quoted at approximately 11:00 A.M., New
     York City time, on such LIBOR Interest Determination Date by three major
     banks in The City of New York selected by the Calculation Agent for loans
     in U.S. dollars to leading European banks having the Index Maturity
     designated in the applicable Pricing Supplement, commencing on
 
                                       S-7
<PAGE>   15
 
     the second London Business Day immediately following such LIBOR Interest
     Determination Date and in a principal amount equal to an amount of not less
     than $1,000,000 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 mentioned in this
     sentence, LIBOR with respect to such LIBOR Interest Determination Date will
     be the interest rate otherwise in effect on such LIBOR Interest
     Determination Date.
 
  Prime Rate
 
     Unless otherwise indicated in the applicable Supplement, "Prime Rate"
means, with respect to any Prime Interest Determination Date, the rate set forth
in H.15(519) for such date opposite the caption "Bank Prime Loan," or, if not so
published by 9:00 A.M., New York City time, on the Calculation Date pertaining
to such Prime Interest Determination Date, the Prime Rate will be calculated by
the Calculation Agent and will be the arithmetic mean of the rates of interest
publicly announced by each bank named on the Reuters Screen NYMF Page as such
bank's prime rate or base lending rate as in effect for such Prime Interest
Determination Date as quoted on the Reuters Screen NYMF Page on such Prime
Interest Determination Date, or, if fewer than four such rates appear on the
Reuters Screen NYMF Page for such Prime 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 Prime Interest Determination Date by at least two of the three major money
center banks in The City of New York selected by the Calculation Agent from
which quotations are requested. If fewer than two quotations are quoted as
aforesaid, the Prime Rate for such Prime Interest Determination Date shall be
calculated by the Calculation Agent and shall be the arithmetic means of the
prime rates quoted in The City of New York on such date by the appropriate
number of substitute banks or trust companies organized and doing business under
the laws of the United States, or any State thereof, having total equity capital
of at least $500 million and being subject to supervision or examination by a
federal or State authority, selected by the Calculation Agent to quote such rate
or rates; provided, however, that if 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 this sentence, the Prime Rate with respect to such Prime
Interest Determination Date will be the interest rate otherwise in effect on
such Prime Interest Determination Date. "Reuters Screen NYMF Page" means the
display designated as page "NYMF" on the Reuters Monitor Money Rates Service (or
such other page as may replace page NYMF on that service for the purpose of
displaying prime rates or base lending rates of major United States banks).
 
  Treasury Rate
 
     Unless otherwise indicated in the applicable Supplement, "Treasury Rate"
means, with respect to any Treasury Interest Determination Date, the rate for
the most recent auction of direct obligations of the United States ("Treasury
bills") having the Index Maturity designated in the applicable Supplement as
published in H.15(519) under the heading "U.S. Government Securities--Treasury
Bills--Auction Average (Investment)" or, if not so published by 9:00 A.M., New
York City time, on the Calculation Date pertaining to such Treasury Interest
Determination Date, the Treasury Rate will be the auction average rate
(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. If the results of the auction of Treasury
bills having the Index Maturity designated in the applicable Supplement 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 in a particular week, then
the Treasury Rate will be calculated by the Calculation Agent and will be a
yield to maturity, expressed as a bond equivalent (determined as described
above) of the arithmetic mean of the secondary market bid rates, as of
approximately 3:30 P.M., New York City time, on such Treasury Interest
Determination Date, of three leading primary 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
Supplement; provided, however, that if the dealers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Treasury
Rate with respect to such Treasury Interest Determination Date will be the
Treasury Rate then in effect on such Treasury Interest Determination Date.

<PAGE>   16
 
  Fed Funds Rate
 
     Unless otherwise indicated in the applicable Supplement, "Fed Funds Rate"
means, with respect to any Fed Funds Interest Determination Date, the rate on
such date for Federal Funds as such rate shall be published in H.15(519) under
the heading "Federal Funds (Effective)" or, if not so published by 9:00 A.M.,
New York City time, on the Calculation Date pertaining to such Fed Funds
Interest Determination Date, the Fed Funds Rate will be the rate on such Fed
Funds Interest Determination Date as published in Composite Quotations under the
heading "Federal Funds/Effective Rate". If such rate is not published by 3:00
P.M., New York City time, on such Calculation Date, then the Fed Funds Rate on
such Fed Funds Interest Determination Date will be calculated by the Calculation
Agent and will be the arithmetic mean of the rates as of 9:00 A.M., New York
City time, on such Fed Funds Interest Determination Date for the last
transaction in overnight Federal Funds 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 Fed Funds
Rate with respect to such Fed Funds Interest Determination Date will be the Fed
Funds Rate in effect on such Fed Funds Interest Determination Date.
 
  CD Rate
 
     Unless otherwise indicated in the applicable Supplement, "CD Rate" means,
with respect to any CD Interest Determination Date, the rate on such date for
negotiable certificates of deposit having the Index Maturity designated in the
applicable Supplement as published in H.15(519) under the heading "CDs
(Secondary Market)" or, if not so published by 9:00 A.M., New York City time, on
the Calculation Date pertaining to such CD Interest Determination Date, the CD
Rate will be the rate on such CD Interest Determination Date for negotiable
certificates of deposit of the Index Maturity designated in the applicable
Supplement as published in Composite Quotations under the heading "Certificates
of Deposit". If such rate is not published by 3:00 P.M., New York City time, on
such Calculation Date, then the CD Rate on such CD 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
CD Interest Determination Date, 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 market banks (in the market for negotiable certificates of deposit) with a
remaining maturity closest to the Index Maturity designated in the applicable
Supplement in a denomination of $5,000,000 or, if greater, an amount that is
representative for a single transaction in the relevant market at the time;
provided, however, that if the dealers selected as aforesaid by the Calculation
Agent are not quoting as mentioned in this sentence, the CD Rate with respect to
such CD Interest Determination Date will be the CD Rate in effect on such CD
Interest Determination Date.
 
INDEXED NOTES
 
     Notes may be issued as Indexed Notes, the principal amounts payable at
Maturity and/or the interest rate to be paid thereon to be determined by
reference to the relationship between two or more currencies, to the price of
one or more specified securities or commodities, to one or more securities or
commodities exchange indices or other indices or by other similar methods or
formulas. The Supplement relating to such an Indexed Note will describe, as
applicable, the method by which the amount of interest payable on any Interest
Payment Date and the amount of principal payable at Maturity in respect of such
Indexed Note will be determined, certain special tax consequences of the
purchase, ownership or disposition of such Indexed Notes, certain risks
associated with an investment in such Indexed Notes and other information
relating to such Indexed Notes.
 
     Unless otherwise specified in the applicable Supplement, the maximum
principal amount payable at Maturity in respect of any Indexed Note will be an
amount equal to twice the face amount thereof and the minimum principal amount
so payable will be zero.
 
     Unless otherwise specified in the applicable Supplement, (i) for purposes
of determining whether Holders of the requisite principal amount of Securities
outstanding under the Indenture have made a demand or given a notice or waiver
or taken any other action, the outstanding principal amount of Indexed Notes
will be deemed to be the U.S. dollar equivalent, determined on the Original
Issue Date of such Indexed Note, of such principal and
 
                                       S-9
<PAGE>   17
 
(ii) if the payment of principal of and interest on any Indexed Note is
accelerated in accordance with the provisions described under "Description of
Securities--Events of Default, Notice and Waiver" in the Prospectus, then the
Company shall pay to the Holder of such Indexed Note on the date of acceleration
the principal amount determined by reference to the formula by which the
principal amount of such Indexed Note would be determined on the Stated Maturity
thereof, as if the date of acceleration were the Stated Maturity.
 
     An investment in Indexed Notes entails significant risks, including wide
fluctuations in market value as well as in the amounts of payments due
thereunder, that are not associated with a similar investment in a conventional
debt security. Such risks depend on a number of factors including supply and
demand for the particular commodity and economic and political events over which
the Company has no control. Fluctuations in the price of any particular security
or commodity, in the rates of exchange between particular currencies or in
particular indices that have occurred in the past are not necessarily
indicative, however, of fluctuations in the price of rates of exchange that may
occur during the term of any Indexed Notes. Accordingly, prospective investors
should consult their own financial and legal advisors as to the risks entailed
by an investment in Indexed Notes. Indexed Notes are not an appropriate
investment for investors who are unsophisticated with respect to securities,
commodities and/or foreign currency transactions.
 
AMORTIZING NOTES
 
     The Company may from time to time offer Amortizing Notes. Unless otherwise
specified in the applicable Supplement, interest on each Amortizing Note will be
computed on the basis of a 360-day year of twelve 30-day months. 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.
Further information concerning additional terms and conditions of any issue of
Amortizing Notes will be provided in the applicable Supplement. A table setting
forth repayment information in respect of each Amortizing Note will be included
in the applicable Supplement and set forth on such Notes.
 
INTEREST RATE RESET
 
     If the Company has the option with respect to any Note to reset the
interest rate, in the case of a Fixed Rate Note, or to reset the Spread and/or
Spread Multiplier, in the case of a Floating Rate Note, the Supplement relating
to such Note will indicate such option, and, if so, (i) the date or dates on
which such interest rate or such Spread and/or Spread Multiplier, as the case
may be, may be reset (each an "Optional Reset Date") and (ii) the basis or
formula, if any, for such resetting.
 
     The Company may exercise such option with respect to a Note by notifying
the Paying Agent of such exercise at least 45 but not more than 60 days prior to
an Optional Reset Date for such Note. Not later than 40 days prior to such
Optional Reset Date, the Paying Agent will mail to the Holder of such Note a
notice (the "Reset Notice"), first class, postage prepaid, setting forth (i) the
election of the Company to reset the interest rate, in the case of a Fixed Rate
Note, or the Spread and/or Spread Multiplier, in the case of a Floating Rate
Note, (ii) such new interest rate or such new Spread and/or Spread Multiplier,
as the case may be, and (iii) the provisions, if any, for redemption during the
period from such Optional Reset Date to the next Optional Reset Date or, if
there is no such next Optional Reset Date, to the Stated Maturity of such Note
(each such period a "Subsequent Interest Period"), including the date or dates
on which or the period or periods during which and the price or prices at which
such redemption may occur during such Subsequent Interest Period.
 
     Notwithstanding the foregoing, not later than 20 days prior to an Optional
Reset Date for a Note, the Company may, at its option, revoke the interest rate,
in the case of a Fixed Rate Note, or the Spread and/or Spread Multiplier, in the
case of a Floating Rate Note, in either case provided for in the Reset Notice
and establish a higher interest rate, in the case of a Fixed Rate Note, or a
higher Spread and/or Spread Multiplier, in the case of a Floating Rate Note, for
the Subsequent Interest Period commencing on such Optional Reset Date by mailing
or causing the Paying Agent to mail notice of such higher interest rate or
higher Spread and/or Spread Multiplier, as the case may be, first class, postage
prepaid, to the Holder of such Note. Such notice will be irrevocable. All Notes
with respect to which the interest rate or Spread and/or Spread Multiplier is
reset on an Optional Reset
 
                                      S-10
<PAGE>   18
 
Date will bear such higher interest rate, in the case of a Fixed Rate Note, or
higher Spread and/or Spread Multiplier, in the case of a Floating Rate Note.
 
     If the Company elects to reset the interest rate or the Spread and/or
Spread Multiplier of a Note, the Holder of such Note will have the option to
elect repayment of such Note by the Company on any Optional Reset Date at a
price equal to the principal amount thereof plus any accrued interest to such
Optional Reset Date. In order for a Note to be so repaid on an Optional Reset
Date, the Holder thereof must follow the procedures set forth below under
"Redemption and Repayment" for optional repayment, except that the period for
delivery of such Note or notification to the Paying Agent will be a least 25 but
not more than 35 days prior to such Optional Reset Date and except that a Holder
who has tendered a Note for repayment pursuant to a Reset Notice may by written
notice to the Paying Agent revoke any such tender for repayment until the close
of business on the tenth day prior to such Optional Reset Date.
 
EXTENSION OF MATURITY
 
     If the Company has the option to extend the Stated Maturity of any Note for
one or more periods (each an "Extension Period") up to but not beyond the date
(the "Final Maturity Date") set forth in the Supplement relating to such Note,
such Supplement will indicate such option and the basis or formula, if any, for
setting the interest rate, in the case of a Fixed Rate Note, or the Spread
and/or Spread Multiplier, in the case of a Floating Rate Note, applicable to any
such Extension Period.
 
     The Company may exercise such option with respect to a Note by notifying
the Paying Agent of such exercise at least 45 but not more than 60 days prior to
the Stated Maturity of such Note in effect prior to the exercise of such option
(the "Original Stated Maturity"). No later than 40 days prior to the Original
Stated Maturity, the Paying Agent will mail to the Holder of such Note a notice
(the "Extension Notice") relating to such Extension Period, first class, postage
prepaid, setting forth (i) the election of the Company to extend the Stated
Maturity of such Note, (ii) the new Stated Maturity, (iii) in the case of a
Fixed Rate Note, the interest rate applicable to the Extension Period or, in the
case of a Floating Rate Note, the Spread and/or Spread Multiplier applicable to
the Extension Period, and (iv) the provisions, if any, for redemption during the
Extension Period, including the date or dates on which or the period or periods
during which and the price or prices at which such redemption may occur during
the Extension Period. Upon the mailing by the Paying Agent of an Extension
Notice to the Holder of a Note, the Stated Maturity of such Note will be
extended automatically as set forth in the Extension Notice, and, except as
modified by the Extension Notice and as described in the next paragraph, such
Note will have the same terms as prior to the mailing of such Extension Notice.
 
     Notwithstanding the foregoing, not later than 20 days prior to the Original
Stated Maturity for a Note, the Company may, at its option, revoke the interest
rate, in the case of a Fixed Rate Note, or the Spread and/or Spread Multiplier,
in the case of a Floating Rate Note, provided for in the Extension Notice and
establish a higher interest rate, in the case of a Fixed Rate Note, or a higher
Spread and/or Spread Multiplier, in the case of a Floating Rate Note, for the
Extension Period by mailing or causing the Paying Agent to mail notice of such
higher interest rate or higher Spread and/or Spread Multiplier, as the case may
be, first class, postage prepaid, to the Holder of such Note. Such notice will
be irrevocable. All Notes with respect to which the Stated Maturity is extended
will bear such higher interest rate, in the case of a Fixed Rate Note, or higher
Spread and/or Spread Multiplier, in the case of a Floating Rate Note, for the
Extension Period.
 
     If the Company elects to extend the Stated Maturity of a Note, the Holder
of such Note will have the option to elect repayment of such Note by the Company
at the Original Stated Maturity at a price equal to the principal amount thereof
plus any accrued interest to such date. In order for a Note to be so repaid on
the Original Stated Maturity, the Holder thereof must follow the procedures set
forth below under "Redemption and Repayment" for optional repayment, except that
the period for delivery of such Note or notification to the Paying Agent will be
at least 25 but not more than 35 days prior to the Original Stated Maturity and
except that a Holder who has tendered a Note for repayment pursuant to an
Extension Notice may by written notice to the Paying agent revoke any such
tender for repayment until the close of business on the tenth day prior to the
Original Stated Maturity.

RENEWABLE NOTES
 
     The Company may from time to time offer Notes which will mature on an
Interest Payment Date specified in the applicable Pricing Supplement occurring
in or prior to the twelfth month following the Original Issue Date of such Notes
(the "Initial Maturity Date") unless the term of all or any portion of any such
Note (a "Renewable Note") is renewed in accordance with the procedures described
below.
 
     On the Interest Payment Date occurring in the sixth month (unless a
different interval (the "Special Election Interval") is specified in the
applicable Supplement) prior to the Initial Maturity Date of a Renewable Note
(the "Initial Renewal Date") and on the Interest Payment Date occurring in each
sixth month (or in the last month of each Special Election Interval) after such
Initial Renewal Date (each, together with the Initial Renewal Date, a "Renewal
Date"), the term of such Renewable Note may be extended to the Interest Payment
Date occurring in the twelfth month (or, if a Special Election Interval is
specified in the applicable Supplement, the last month in a period equal to
twice the Special Election Interval) after such Renewal Date, if the Holder of
such Renewable Note elects to extend the term of such Renewable Note or any
portion thereof as described below. If a Holder does not elect to extend the
term of any portion of the principal amount of a Renewable Note during the
specified period prior to any Renewal Date, such portion will become due and
payable on the Interest Payment Date occurring in the sixth month (or the last
month in the Special Election Interval) after such Renewal Date (the "New
Maturity Date").
 
     A Holder of a Renewable Note may elect to renew the term of such Renewable
Note, or if so specified in the applicable Supplement, any portion thereof, by
delivering a notice to such effect to the Trustee (or any duly appointed paying
agent) at the Corporate Trust Office not less than 15 nor more than 30 days
prior to such Renewal Date (unless another period is specified in the applicable
Supplement as the "Special Election Period"). Such election will be irrevocable
and will be binding upon each subsequent Holder of such Renewable Note. An
election to renew the term of a Renewable Note may be exercised with respect to
less than the entire principal amount of such Renewable Note only if so
specified in the applicable Supplement and only in such principal amount, or any
integral multiple in excess thereof, as is specified in the applicable
Supplement. Notwithstanding the foregoing, the term of the Renewable Notes may
not be extended beyond the Stated Maturity specified for such Renewable Notes in
the applicable Supplement.
 
     If the Holder does not elect to renew the term, such Renewable Note must be
presented to the Trustee (or any duly appointed paying agent) simultaneously
with notice of such election (or, in the event notice of such election, together
with a guarantee of delivery within five Business Days, is transmitted on behalf
of a Holder from a member of a national securities exchange, the National
Association of Securities Dealers, Inc. (the "NASD") or a commercial bank or
trust company in the United States, within five Business Days of the date of
such notice). With respect to a Renewable Note that is a Certificated Note, as
soon as practicable following receipt of such Renewable Note the Trustee (or any
duly appointed paying agent) will issue in exchange therefor in the name of such
Holder (i) a Note, in a principal amount equal to the principal amount of such
exchanged Renewable Note for which the election to renew the term thereof was
exercised, with terms identical to those specified on such Renewable Note
(except for the Original Issue Date and the Initial Interest Rate and except
that such Note will have a fixed, nonrenewable Stated Maturity on the New
Maturity Date) and (ii) if such election is made with respect to less than the
full principal amount of such Holder's Renewable Note, a replacement Renewable
Note, in a principal amount equal to the principal amount of such exchanged
Renewable Note for which the election was made, with terms identical to such
exchanged Renewable Notes.
 
COMBINATION OF PROVISIONS
 
     If so specified in the applicable Supplement, any Note may be subject to
all of the provisions, or any combination of the provisions, described above
under "Interest Rate Reset," "Extension of Maturity" and "Renewable Notes."
 
REDEMPTION AND REPAYMENT
 
     Unless one or more Redemption Dates ("Redemption Dates") are specified in
the applicable Supplement, the Notes will not be redeemable prior to their
Stated Maturity. If one or more Redemption Dates are so specified
 
                                      S-12
<PAGE>   20
 
with respect to any Note, the applicable Supplement will also specify one or
more redemption prices (expressed as a percentage of the principal amount of
such Note) ("Redemption Prices") and the redemption period or periods
("Redemption Periods") during which such Redemption Prices shall apply. Unless
otherwise specified in the applicable Supplement, any such Note will be
redeemable at the option of the Company at the specified Redemption Price
applicable to the Redemption Period during which such Note is to be redeemed,
together with interest accrued to the Redemption Date. Unless otherwise
specified in the applicable Supplement, the Notes will not be subject to any
sinking fund. The Company may redeem any of the Notes that are redeemable and
remain outstanding either in whole or from time to time in part, upon not less
than 30 nor more than 60 days' notice.
 
     Unless otherwise specified in the applicable Supplement, Notes cannot be
repaid prior to Stated Maturity. If a Note is repayable at the option of the
Holder on a date or dates specified prior to Stated Maturity, the applicable
Supplement will set forth the price or prices of such repayment, together with
accrued interest to the date of repayment.
 
     In order for a Note that is repayable at the option of the Holder to be
repaid, the Paying Agent must receive at least 30 days but not more than 60 days
prior to the repayment date (a) appropriate wire instructions and (b) either (i)
the Note with the form entitled "Option to Elect Repayment" attached to the Note
duly completed or (ii) a telegram, telex, facsimile transmission or letter from
a member of a national securities exchange or 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 portion of the principal amount of
the Note to be repaid, the certificate number or a description of the tenor and
terms of the Note, a statement that the option to elect repayment is being
exercised thereby and a guarantee that the Note to be repaid with the form
entitled "Option to Elect Repayment" attached to the Note duly completed will be
received by the Paying Agent not later than five Business Days after the date of
such telegram, telex, facsimile transmission or letter and such Note and form
duly completed must be received by the Paying Agent by such fifth Business Day.
Exercise of the repayment option by the Holder of a Note will be irrevocable,
except as otherwise described above under "Interest Rate Reset" and "Extension
of Maturity." The repayment option may be exercised by the Holder of a Note for
less than the entire principal amount of the Note provided that the principal
amount of the Note remaining outstanding after repayment is an authorized
denomination. No transfer or exchange of any Note (or, in the event that any
Note is to be repaid in part, the portion of the Note to be repaid) will be
permitted after exercise of a repayment option. All questions as to the
validity, eligibility (including time of receipt) and acceptance of any Note for
repayment will be determined by the Trustee, whose determination will be final,
binding and non-appealable.
 
     IF A NOTE IS REPRESENTED BY A BOOK-ENTRY NOTE, 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.
 
     Notwithstanding anything in this Prospectus Supplement to the contrary,
unless otherwise specified in the applicable Supplement, if a Note is an
Original Issue Discount Note, the amount payable on such Note in the event of
redemption or repayment prior to its Stated Maturity will be the Amortized Face
Amount of such Note, as specified in the applicable Supplement, as of the
Redemption Date or the date of repayment, as the case may be.
 
BOOK-ENTRY NOTES
 
     The Depositary will act as securities depositary for Book-Entry Notes. The
Book-Entry Notes will be issued as fully-registered securities registered in the
name of Cede & Co. (the Depositary's partnership nominee). One fully-registered
Global Security will be issued for each issue of the Notes, each in the
aggregate principal amount of such issue, and will be deposited with the
Depositary. If, however, the aggregate principal amount of any issue
 
                                      S-13
<PAGE>   21
 
exceeds $200 million, one Global Security will be issued with respect to each
$200 million of principal amount and an additional Global Security will be
issued with respect to any remaining principal amount of such issue.
 
     The Depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934, as amended. The Depositary holds securities that its
participants ("Participants") deposit with the Depositary. The Depositary also
facilitates the settlement among Participants of securities transactions, such
as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct participants
("Direct Participants") include securities brokers and dealers, banks, trust
companies, clearing corporations, and certain other organizations. The
Depositary is owned by a number of its Direct Participants and by the New York
Stock Exchange, Inc., the American Stock Exchange, Inc., and the NASD. Access to
the Depositary's system is also available to others such as securities brokers
and dealers, banks and trust companies that clear through or maintain a
custodial relationship with a Direct Participant, either directly or indirectly
("Indirect Participants"). The rules applicable to the Depositary and its
Participants are on file with the Securities and Exchange Commission.
 
     Purchases of Book-Entry Notes under the Depositary's system must be made by
or through Direct Participants, which will receive a credit for the Book-Entry
Notes on the Depositary's records. The ownership interest of each actual
purchaser of each Book-Entry Note ("Beneficial Owner") is in turn to be recorded
on the Direct and Indirect Participants' records. Beneficial Owners will not
receive written confirmation from the Depositary of their purchase, but
Beneficial Owners are expected to receive written confirmations providing
details of the transaction, as well as periodic statements of their holdings,
from the Direct or Indirect Participant through which the Beneficial Owner
entered into the transaction. Transfers of ownership interests in the Book-Entry
Notes are to be accomplished by entries made on the books of Participants acting
on behalf of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interests in Book-Entry Notes, except in the event
that use of the book-entry system for one or more Book-Entry Notes is
discontinued.
 
     To facilitate subsequent transfers, all Global Securities deposited by
Participants with the Depositary are registered in the name of the Depositary's
partnership nominee, Cede & Co. The deposit of Global Securities with the
Depositary and their registration in the name of Cede & Co. effects no change in
beneficial ownership. The Depositary has no knowledge of the actual Beneficial
Owners of the Book-Entry Notes; the Depositary's records reflect only the
identity of the Direct Participants to whose accounts such Book-Entry Notes are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.
 
     Conveyance of notices and other communications by the Depositary to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices will be sent to Cede & Co. If less than all of the
Book-entry Notes are being redeemed, and unless otherwise notified by either the
Company or the Trustee, the Depositary's practice is to determine by lot the
amount of the interest of each Direct Participant in such issue to be redeemed.
 
     Neither the Depositary nor Cede & Co. will consent or vote with respect to
Book-Entry Notes. Under its usual procedures, the Depositary will mail an
Omnibus Proxy to the Company as soon as possible after the record date. The
Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Book-Entry Notes are credited on the record
date (identified in a listing attached to the Omnibus Proxy).
 
     Principal and interest payments on the Book-Entry Notes will be made to the
Depositary. The Depositary's practice is to credit Direct Participants' accounts
on the payable date in accordance with their respective holdings shown on the
Depositary's records unless the Depositary has reason to believe that it will
not receive payment on
 
                                      S-14
<PAGE>   22
 
the payable date. Payments by Participants to Beneficial Owners will be governed
by standing instructions and customary practices as is the case with securities
held for the accounts of customers in bearer form or registered in "street name"
and will be the responsibility of such Participant and not of the Depositary,
any Agents, or the Company, subject to any statutory or regulatory requirements
as may be in effect from time to time. Payment of principal and interest to the
Depositary is the responsibility of the Company or Agents, disbursement of such
payments to Direct Participants will be the responsibility of the Depositary,
and disbursement of such payments to the Beneficial Owners will be the
responsibility of Direct and Indirect Participants.
 
     A Beneficial Owner must give notice to elect to have its Book-Entry Notes
purchased or tendered, through its Participant, to the Paying Agent, and must
effect delivery of such Book-Entry Notes by causing the Direct Participant to
transfer the Participant's interest in the Book-Entry Notes, on the Depositary's
records, to the Paying Agent. The requirement for physical delivery of
Book-Entry Notes in connection with a demand for purchase or a mandatory
purchase will be deemed satisfied when the ownership rights in the Book-Entry
Notes are transferred by Direct Participants on the Depositary's records.
 
     The Depositary may discontinue providing its services as securities
depositary with respect to the Book-Entry Notes at any time by giving reasonable
notice to the Company or the Agents. Under such circumstances, in the event that
a successor securities depositary is not obtained, Certificated Notes are
required to be printed and delivered in exchange for the Book-Entry Notes
represented by the Global Securities held by the Depositary.
 
     The Company may decide to discontinue use of system of book-entry transfers
through the Depositary (or a successor securities depositary). In that event,
Certificated Notes will be printed and delivered in exchange for the Book-Entry
Notes represented by the Global Securities held by the Depositary.
 
     The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that the Company
believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.
 
     Neither the Company, the Trustee, any paying agent nor the registrar for
the Notes will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interest
in a Global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.
 
                              PLAN OF DISTRIBUTION
 
     Under the terms of an Agency Agreement dated April 13, 1995 (the "Agency
Agreement"), the Notes are offered on a continuing basis by the Company through
the Agents, which have agreed to use their best efforts to solicit purchases of
the Notes. The Company will pay each Agent a commission of from .125% to .625%
of the principal amount of each Note, depending on its stated maturity, sold
through such Agent. Commissions with respect to Notes with stated maturities in
excess of 30 years that are sold through an Agent will be negotiated between the
Company and such Agent at the time of such sale. The Company will have the sole
right to accept offers to purchase Notes and may reject any such offer, in whole
or in part. Each Agent will have the right, in its discretion reasonably
exercised, without notice to the Company, to reject any offer to purchase Notes
received by it, in whole or in part. The Company also may sell Notes to each
Agent, acting as principal, at or above par or at a discount to be agreed upon
at the time of sale, for resale to one or more investors or to one or more
broker-dealers (acting as principal for purposes of resale) at varying prices
related to prevailing market prices at the time of such resale, as determined by
such Agent or, if so agreed, at a fixed public offering price. Unless otherwise
specified in the applicable Supplement, any Note sold to an Agent as principal
will be purchased by such Agent at a price equal to 100% of the principal amount
thereof less a percentage equal to the commission applicable to an agency sale
of a Note of identical maturity. The Company has reserved the right to sell
Notes directly on its own behalf.
 
     An Agent may sell Notes it has purchased from the Company as principal to
other dealers for resale to investors and other purchasers, and may allow any
portion of the discount received in connection with such purchase from the
Company to such dealers. After the initial public offering of Notes, the public
offering price (in the case of Notes to be resold at a fixed public offering
price), the concession and the discount may be changed.
 
                                      S-15
<PAGE>   23
 
     Unless otherwise indicated in the applicable Supplement, payment of the
purchase price of Notes will be required to be made in funds immediately
available in New York City.
 
     The Agents may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933, as amended. The Company has agreed to indemnify the
Agents against and contribute toward certain liabilities, including liabilities
under such Act. The Company has agreed to reimburse the Agents for certain
expenses.
 
     The Company also may sell Notes or other medium-term notes on its own
behalf directly to its members. Any Notes so sold by the Company to its members
will reduce the remaining principal amount of Notes which may be offered by this
Prospectus Supplement and the Prospectus.
 
     In addition to offering Notes as described herein, Securities which are
medium-term notes and may have terms substantially similar to the terms of the
Notes offered hereby (but constituting one or more separate series of the
Securities for purposes of the Indenture) may be offered in the future on a
continuing basis primarily in Europe ("Euro Medium-Term Notes") by the Company
pursuant to a Placement Agent Agreement with Lehman Brothers International,
Inc., Union Bank of Switzerland (Securities) Limited and such other firms as may
be named (the "European Agents") as agents for the Company. The terms of such
Placement Agency Agreement are expected to be substantially similar to the terms
of the Agency Agreement, except for certain selling restrictions specified in
the Placement Agency Agreement. Any Securities sold pursuant to such Placement
Agency Agreement, or sold by the Company to the European Agents for resale as
contemplated by such Placement Agency Agreement, will reduce the remaining
principal amount of Notes which may be offered by this Prospectus Supplement and
the Prospectus.
 
     The Agents engage in transactions with and perform services for the Company
and certain of its affiliates in the ordinary course of business.

     National Rural Utilities Cooperative Finance Corporation ("CFC" or the
"Company") intends to issue from time to time debt securities (the "Securities")
each of which will be a direct, unsecured obligation of the Company and which
will be offered to the public on terms determined by market conditions at the
time of sale, and/or Warrants to purchase Securities (the "Warrants"). The

foreign currency or a currency unit, (i) directly to purchasers, (ii) through
agents designated from time to time or (iii) through underwriters or a group of
underwriters which may include Lehman Brothers Inc. and Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated.
     The Securities may be issued in registered form without coupons, in a form

Securities may be issued in temporary or definitive global form. Securities in
bearer form are offered only to non-United States persons and to offices located
outside the United States of certain United States financial institutions. See
"Limitations on Issuance of Bearer Securities".
     The Securities and Warrants may be sold for U.S. dollars, foreign
currencies or foreign currency units, and the principal (including any premium)
and any interest on the Securities may be payable in U.S. dollars, foreign
currencies or foreign currency units. The Securities may be issued in one or

sets forth a description of the Offered Securities for which each Warrant is
exercisable and the offering price, if any, exercise price, duration and other
terms of such Warrant. Warrants may be sold in units with Securities or in
separate offerings, as specified in a Prospectus Supplement.

                                  THE COMPANY
 
     National Rural Utilities Cooperative Finance Corporation ("CFC" or the
"Company") was incorporated as a private, not-for-profit cooperative association
under the laws of the District of Columbia in 1969. The principal purpose of CFC
is to provide its members with a source of financing to supplement the loan
program of the Rural Utilities Service ("RUS") (formerly the Rural
Electrification Administration) of the United States Department of Agriculture.
CFC makes loans primarily to its rural utility system members ("Utility
Members") to enable them to acquire, construct and operate electric
distribution, generation, transmission and related facilities. CFC also makes
loans to service organization members ("Service Members") to finance office
buildings, equipment, related facilities and services provided by them to the
rural utility systems. CFC has also provided guarantees for tax-exempt financing
of pollution control facilities and other properties constructed or acquired by
its members, and in addition has provided loans or guarantees through National
Cooperative Services Corporation ("NCSC") in connection with certain lease
transactions of its members. Also, through Rural Telephone Finance Cooperative
("RTFC"), a controlled affiliate of CFC established in 1987, CFC provides
financing to rural telephone and telecommunications companies and their
affiliates. In addition, through Guaranty Funding Cooperative, ("GFC"), a
controlled affiliate of CFC established in 1991, CFC provides financing for
members to refinance their debt to the Federal Financing Bank of the United
States Treasury ("FFB"). CFC's offices are located at Woodland Park, 2201
Cooperative Way, Herndon, VA 22071 and its telephone number is (703) 709-6700.
 
     CFC's 1,039 members as of May 31, 1994, included 899 Utility Members,
virtually all of which are consumer-owned cooperatives, 71 Service Members and
69 associate members. The Utility Members included 833 distribution systems and
66 generation and transmission ("Power Supply") systems operating in 46 states
and U.S. territories. At December 31, 1993, CFC's member systems served
approximately 12.4 million consumers, representing service to an estimated 32.5
million ultimate users of electricity, and owned approximately $62.6 billion
(before depreciation of $17.9 billion) in total utility plant.
 
     CFC's long-term loans to Utility Members generally have 35-year maturities.
They are made primarily in conjunction with concurrent RUS loans and are
generally secured ratably with RUS's loans by a common mortgage on substantially
all the Utility Member's property (including revenues). Interest rates on these
loans are either fixed or variable. Fixed rates are offered weekly based on
CFC's overall cost of long-term capital and may be obtained for any period from
one to 30 years. Variable rates are adjusted monthly in line with changes in
CFC's cost of short-term funds.
 
     CFC makes short-term unsecured line-of-credit loans and secured
intermediate-term loans with up to five-year maturities. Rates on these loans
may be adjusted semi-monthly in line with changes in CFC's short-term cost of
funds. The intermediate-term loans are generally made to Power Supply systems in
connection with the planning and construction of new generating plants and
transmission facilities.
 
     CFC also makes loans to telecommunication systems through RTFC. Such loans
are long-term fixed or variable rate loans with maturities not exceeding 15
years and short-term loans.
 
     CFC's guarantees are senior obligations ranking on a par with its other
senior debt. Even if the system defaults in payment of the guaranteed
obligations, the debt cannot be accelerated as long as CFC pays the debt service
under its guarantee as due. The system is generally obligated to reimburse CFC
on demand for amounts paid on the guarantee, and this obligation is usually
secured by a mortgage (often joint with RUS) on the system's property or, in the
case of a lease transaction, on the leased property. Holders of $1,214.6 million
of the guaranteed pollution control debt (at May 31, 1994) have the right at
certain times to tender their bonds for remarketing, and, if they cannot
otherwise be remarketed, CFC has committed to purchase bonds so tendered.
 
     By policy, CFC maintains an allowance for loan and guarantee losses at a
level believed to be adequate in relation to the quality and size of its loans
and guarantees outstanding. At May 31, 1994, the allowance was $188.2 million.
At May 31, 1994, CFC's ten largest borrowers, which were all Power Supply
members, had outstanding loans totaling $461.6 million (excluding $394.1 million
of loans guaranteed by RUS), which represented approximately 7.5% of CFC's total
loans outstanding. As of May 31, 1994, outstanding guarantees for these same ten
largest borrowers totaled $2,117.7 million, which represented 79.2% of CFC's
total guarantees outstanding, including guarantees of the maximum amounts of
lease obligations at such date. On that date, no
 
                                        3
<PAGE>   28
 
member had loans and guarantees outstanding in excess of 10% of the aggregate
amount of CFC's outstanding loans and guarantees; however, one of the ten
largest borrowers, Deseret Generation & Transmission Co-operative ("Deseret"),
was in financial difficulty. At May 31, 1994, Deseret accounted for 1.8% of
loans outstanding (excluding loans guaranteed by RUS) and 12.6% of guarantees
outstanding and represented 26.8% of total Members' Equity, Members'
Subordinated Certificates and the allowance for loan and guarantee losses.

                                USE OF PROCEEDS
 
     Except as may be otherwise provided in a Prospectus Supplement, the net
proceeds from the sale of the Securities will be added to the general funds of
the Company and will be available for making loans to members, the repayment of
short-term borrowings, the refinancing of existing long-term debt and for other
corporate purposes. The Company expects to incur additional indebtedness from
time to time, the amount and terms of which will depend upon the volume of its
business, general market conditions and other factors.
 
                           DESCRIPTION OF SECURITIES
 
     The following description of the Securities summarizes certain general
terms and provisions of the Securities to which any Prospectus Supplement may
relate. The particular terms of the Securities and the extent, if any, to which
such general provisions may apply to any series of Securities will be described
in the Prospectus Supplement relating to such series.
 
     The Securities are to be issued under an Indenture dated as of December 15,
1987, as supplemented by a First Supplemental Indenture dated as of October 1,
1990 between the Company and Harris Trust and Savings Bank, as successor Trustee
(as so supplemented, the "Indenture"). The Indenture does not limit the
aggregate principal amount of Securities which may be issued thereunder.
 
     The statements under this heading are subject to the detailed provisions of
the Indenture and the Securities. Whenever particular provisions of the
Indenture and the Securities or terms defined therein are referred to, such
provisions or definitions are incorporated by reference herein as a part of the
statements made and the statements are qualified in their entirety by such
reference.
 
GENERAL
 
     The Securities may be issued in fully registered form without coupons
("Registered Securities"), or in a form registered as to principal only with or
without coupons or in bearer form with or without coupons ("Bearer Securities")
or any combination thereof. Securities may also be issued in temporary or
definitive global bearer form. Unless otherwise specified in the Prospectus
Supplement accompanying the Offered Securities, the Securities will be only
Registered Securities. The Securities denominated in U.S. dollars will be
issued, unless otherwise set forth in the Prospectus Supplement accompanying the
Offered Securities, in denominations of $1,000 or an integral multiple thereof
for Registered Securities, and in denominations of $5,000 or an integral
multiple thereof for Bearer Securities.
 
     The Securities will be direct, unsecured obligations of the Company.
 
                                        4
<PAGE>   29
 
     If any of the Securities are sold for any foreign currency or currency unit
or if principal of (or premium, if any) or any interest on any of the Securities
is payable in any foreign currency or currency unit, the restrictions,
elections, tax consequences, specific terms and other information with respect
to such issue of Securities and such foreign currency or currency unit will be
set forth in the Prospectus Supplement relating thereto.
 
     The Securities may be issued in one or more series with the same or various
maturities at or above par or with an original issue discount. Offered
Securities bearing no interest or interest at a rate which at the time of
issuance is below market rates ("Original Issue Discount Securities") will be
sold at a discount (which may be substantial) below their stated principal
amount. See "United States Taxation--U.S. Holders--Original Issue Discount" for
a discussion of certain Federal income tax considerations with respect to any
such Original Issue Discount Securities.
 
     Reference is made to the Prospectus Supplement for the following terms of
the Offered Securities: (i) the title and the limit, if any, on the aggregate
principal amount of Offered Securities; (ii) the percentage of their principal
amount at which the Offered Securities will be sold; (iii) the date or dates on
which the Offered Securities will mature; (iv) the rate or rates (which may be
fixed or variable) per annum, if any, at which the Offered Securities will bear
interest or the method of determining such rate or rates; (v) the date or dates
from which such interest, if any, shall accrue and the date or dates at which
such interest, if any, will be payable; (vi) the place where the principal of
(and premium, if any) and the interest, if any, on the Offered Securities will
be payable; (vii) the terms for redemption for early payment, if any, including
any mandatory or optional sinking fund or analogous provision; (viii) the
principal amount of the Offered Securities which are Original Issue Discount
Securities payable upon declaration of acceleration of the maturity of the
Offered Securities; (ix) the means of satisfaction and discharge of the
Indenture with respect to the Offered Securities; (x) any deletions or
modifications of or additions to the Events of Default or covenants of the
Company; (xi) the currency, currencies or currency unit or units for which the
Offered Securities may be purchased and the currency, currencies or currency
unit or units in which the payment of principal of (and premium, if any) and
interest, if any, on such Offered Securities will be made and, if the Company or
the Holders of Offered Securities may elect for such payment in a currency,
currencies or currency unit or units other than that in which the Offered
Securities are stated to be payable, then the period or periods within which,
and the terms and conditions upon which, such election may be made and, if the
amount of such payments may be determined with reference to an index based on a
currency, currencies or currency unit or units, other than that in which the
Offered Securities are stated to be payable, then the manner in which such
amounts shall be determined; (xii) whether the Offered Securities will be issued
in registered form without coupons, in a form registered as to principal only
with or without coupons, in bearer form with or without coupons, including
temporary and definitive global form, or any combination thereof and the
circumstances, if any, upon which such Offered Securities may be exchanged for
Offered Securities issued in a different form; (xiii) whether and under what
circumstances the Company will pay additional amounts to any Holder of Offered
Securities who is not a United States person (as defined under "United States
Taxation") in respect of any tax, assessment or governmental charge required to
be withheld or deducted and, if so, whether the Company will have the option to
redeem rather than pay additional amounts; (xiv) whether the covenants described
below under "Restriction on Indebtedness" will not apply to the Offered
Securities; and (xv) any other terms of the Offered Securities not inconsistent
with the Indenture. (Section 301)
 
EXCHANGE, REGISTRATION AND TRANSFER
 
     Unless otherwise specified in the applicable Prospectus Supplement,
Registered Securities of any series will be exchangeable for other Registered
Securities of the same series and of a like aggregate principal amount and tenor
of different authorized denominations. In addition, if Securities of any series
are issuable as both Registered Securities and Bearer Securities, at the option
of the Holder upon request confirmed in writing, and subject to the terms of the
Indenture, Bearer Securities (with all unmatured coupons, except as provided
below, and all matured coupons in default) of such series will be exchangeable
into Registered Securities of the same series of any authorized denominations
and of a like aggregate principal amount and tenor. Bearer Securities with
coupons appertaining thereto surrendered in exchange for Registered Securities
between a Regular Record Date or a Special Record Date and the relevant date for
payment of interest must be surrendered without the coupon relating to such date
for payment of interest and interest will not be payable in respect of the
Registered Security issued in
 
                                        5
<PAGE>   30
 
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the terms of the Indenture. Bearer
Securities will not be issued in exchange for Registered Securities. No service
charge will be made for any registration of transfer or exchange of the
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge in connection therewith. (Section 305)
 
     Unless otherwise specified in the applicable Prospectus Supplement,
Securities may be presented for exchange as provided above, and Registered
Securities may be presented for registration of transfer (with the form of
transfer endorsed thereon duly executed), at the office of the Security
Registrar or at the office of any transfer agent designated by the Company for
such purpose with respect to any series of Securities and referred to in an
applicable Prospectus Supplement. Such transfer or exchange will be effected
upon the Security Registrar or such transfer agent, as the case may be, being
satisfied with the documents of title and identity of the person making the
request. The Company has appointed Bank of Montreal Trust Company as Security
Registrar. (Section 305) If a Prospectus Supplement refers to any transfer
agents (in addition to the Security Registrar) initially designated by the
Company with respect to any series of Securities, the Company may at any time
rescind the designation of any such transfer agent or approve a change in the
location through which any such transfer agent acts, except that, if Securities
of a series are issuable solely as Registered Securities, the Company will be
required to maintain a transfer agent in each Place of Payment for such series
and, if Securities of a series are issuable as Bearer Securities, the Company
will be required to maintain (in addition to the Security Registrar) a transfer
agent in a Place of Payment for such series. The Company may at any time
designate additional transfer agents with respect to any series of Securities.
(Section 1002)
 
     In the event of any redemption in part, the Company will not be required
to: (i) issue, register the transfer of or exchange Securities of any series
during a period beginning at the opening of business 15 days before any
selection of Securities of that series to be redeemed and ending at the close of
business on (a) if Securities of the series are issuable only as Registered
Securities, the day of mailing of the relevant notice of redemption and (b) if
Securities of the series are issuable only as Bearer Securities, the day of the
first publication of the relevant notice of redemption or, if Securities of the
series are also issuable as Registered Securities and there is no publication,
the day of mailing of the relevant notice of redemption; (ii) register the
transfer of or exchange any Registered Security, or portion thereof, called for
redemption, except the unredeemed portion of any Registered Security being
redeemed in part; or (iii) exchange any Bearer Security called for redemption,
except to exchange such Bearer Security for a Registered Security of that series
and like tenor which is simultaneously surrendered for redemption. (Section 305)
 
PAYMENT AND PAYING AGENTS
 
     Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Registered Securities
will be made at the office of such Paying Agent or Paying Agents as the Company
may designate from time to time, except that at the option of the Company
payment of any interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register. (Section
301) Unless otherwise indicated in an applicable Prospectus Supplement, payment
of any installment of interest on Registered Securities will be made to the
Person in whose name such Registered Security is registered at the close of
business on the Regular Record Date for such interest. (Section 307)
 
     Unless otherwise indicated in an applicable Prospectus Supplement, the
office of Bank of Montreal Trust Company in the Borough of Manhattan, The City
of New York will be designated as the Company's sole Paying Agent for payments
with respect to Offered Securities that are issuable solely as Registered
Securities and as the Company's Paying Agent in the Borough of Manhattan, The
City of New York, for payments with respect to Offered Securities. Any Paying
Agents outside the United States and any other Paying Agents in the United
States initially designated by the Company for the Offered Securities will be
named in an applicable Prospectus Supplement. The Company may at any time
designate additional Paying Agents or rescind the designation of any Paying
Agent or approve a change in the office through which any Paying Agent acts,
except that, unless otherwise indicated in an applicable Prospectus Supplement,
if Securities of a series are issuable solely as Registered Securities, the
Company will be required to maintain a Paying Agent in each Place of Payment for
 
                                        6
<PAGE>   31
 
such series and, if Securities of a series are issuable as Bearer Securities,
the Company will be required to maintain (i) a Paying Agent in the Borough of
Manhattan, The City of New York, for payments with respect to any Registered
Securities of the series (and for payments with respect to Bearer Securities of
the series in certain circumstances) and (ii) a Paying Agent in a Place of
Payment located outside the United States where Bearer Securities of such series
and any coupons appertaining thereto may be presented and surrendered for
payment. (Section 1002)
 
     All moneys paid by the Company to a Paying Agent for the payment of
principal of (and premium, if any) or any interest on any Security or coupon
that remains unclaimed at the end of two years after such principal, premium or
interest shall have become due and payable will be repaid to the Company and the
Holder of such Security or coupon will thereafter, as an unsecured general
creditor, look only to the Company for payment thereof. (Section 1003)
 
RESTRICTION ON INDEBTEDNESS
 
     The Company may not incur any Superior Indebtedness or make any optional
prepayment on any Capital Term Certificate if, as a result, the principal amount
of Superior Indebtedness outstanding, less a principal amount thereof equal to
the principal amount of Government or Government Insured Obligations (as defined
in the Indenture) held by the Company, thereafter or on any future date would
exceed 20 times the sum of the Members' equity in the Company at the time of
determination plus the principal amount of Capital Term Certificates outstanding
at the time of determination or at such given future date, as the case may be.
The principal amounts of Superior Indebtedness and Capital Term Certificates to
be outstanding on any future given date will be computed after giving effect to
maturities and sinking fund requirements. (Section 1007) "Superior Indebtedness"
means all indebtedness of the Company (including all guarantees by the Company
of indebtedness of others) except Capital Term Certificates. A "Capital Term
Certificate" is defined for the purposes of the Indenture as a note of the
Company substantially in the form of the capital term certificates of the
Company outstanding on the date of the Indenture and any other indebtedness
having substantially similar provisions as to subordination. As of May 31, 1994,
the Company had $6,772,325,000 outstanding of Superior Indebtedness and within
the restrictions of the Indenture was permitted to have outstanding an
additional $22,904,195,000 of Superior Indebtedness.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Indenture provides that the Company, without the consent of the Holders
of any of the Outstanding Securities, may consolidate with or merge into any
other corporation or transfer its assets substantially as an entirety to any
Person provided that: (i) the successor is a corporation organized under the
laws of any domestic jurisdiction; (ii) the successor corporation assumes the
Company's obligations under the Indenture and the Securities issued thereunder;
(iii) immediately after giving effect to the transaction, no Event of Default
(as defined below under "Events of Default, Notice and Waiver") and no event
that, after notice or lapse of time, or both, would become an Event of Default,
shall have occurred and be continuing; and (iv) certain other conditions are
met. (Section 801)
 
MODIFICATION OF THE INDENTURE
 
     The Indenture provides that the Company and the Trustee may, without the
consent of any Holders of Securities, enter into supplemental indentures for the
purposes, among other things, of adding to the Company's covenants, adding
additional Events of Default, establishing the form or terms of Securities of
any series, changing or eliminating any restriction on the manner or place of
payment of principal of or interest on Bearer Securities or, provided such
action shall not adversely affect the interests of the Holders of any series of
Securities in any material respect, curing ambiguities or inconsistencies in the
Indenture or making other provisions with respect to matters arising under the
Indenture. (Section 901)
 
     The Indenture contains provisions permitting the Company, with the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Securities of all affected series (acting as one class), to execute
supplemental indentures adding any provisions to or changing or eliminating any
of the provisions of the
 
                                        7
<PAGE>   32
 
Indenture or modifying the rights of the Holders of the Securities of such
series, except that no such supplemental indenture may, without the consent of
the Holders of all the Outstanding Securities affected thereby, among other
things: (i) change the maturity of the principal of, or any installment of
principal of or interest on, any of the Securities; (ii) reduce the principal
amount thereof (or any premium thereon) or the rate of interest, if any,
thereon; (iii) reduce the amount of the principal of Original Issue Discount
Securities payable on any acceleration of maturity; (iv) change the currency,
currencies or currency unit or units in which any of the Securities or any
premium or interest thereon is payable; (v) change any obligation of the Company
to maintain an office or agency in the places and for the purposes required by
the Indenture; (vi) impair the right to institute suit for the enforcement of
any payment on or after the applicable maturity date; (vii) reduce the
percentage in principal amount of the Outstanding Securities of any series, the
consent of the Holders of which is required for any such supplemental indenture
or for any waiver of compliance with certain provisions of, or of certain
defaults under, the Indenture; or (viii) with certain exceptions, to modify the
provisions for the waivers of certain covenants and defaults and any of the
foregoing provisions. (Section 902)
 
WAIVER OF CERTAIN COVENANTS
 
     The Indenture provides that the Company may omit to comply with certain
restrictive covenants (including that described above under "Restriction on
Indebtedness") if the Holders of not less than a majority in principal amount of
all series of Outstanding Securities affected thereby (acting as one class)
waive compliance with such restrictive covenants. (Section 1009)
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     An Event of Default in respect of any series of Securities (unless it is
either inapplicable to a particular series or has been modified or deleted with
respect to any particular series) is defined in the Indenture to be: (i) a
default for 30 days in the payment of any installment of interest upon any of
the Securities of such series when due; (ii) a default in the payment of
principal of (or premium, if any, on) any of the Securities of such series when
due; (iii) a default in the deposit of any sinking fund payment when the same
becomes due by the terms of the Securities of such series; (iv) a default in the
performance, or breach, of the covenant of the Company described above under
"Restrictions on Indebtedness" which shall not have been remedied for a period
of 60 days after such default has become known to an officer of the Company; (v)
a default by the Company in the performance, or breach, of any of its other
covenants or warranties in the Indenture which shall not have been remedied for
a period of 60 days after notice from the Trustee thereunder or the Holder of
not less than 25% in principal amount of the Outstanding Securities of such
series; (vi) certain events of bankruptcy, insolvency or reorganization of the
Company; and (vii) such other events as may be specified for each series.
(Section 501)
 
     The Indenture provides that if an Event of Default specified therein in
respect of any series of Outstanding Securities shall have happened and be
continuing, either the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities of such series may declare the principal
(or, if such Securities are Original Issue Discount Securities, such portion of
the principal amount as may be specified by the terms of such Securities) of all
of the Outstanding Securities of such series to be immediately due and payable.
(Section 502)
 
     The Indenture provides that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that such Trustee may act in
any way that is not inconsistent with such directions and may decline to act if
any such direction is contrary to law or to the Indenture or would involve such
Trustee in personal liability. (Section 507)
 
     The Indenture provides that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all of the Outstanding Securities of such series waive any past
default with respect to such series and its consequences, except a default (i)
in the payment of the principal of (or premium, if any) or any interest on any
of the Securities of such series or (ii) in respect of a covenant or provision
which, under the terms of the Indenture, cannot be modified or amended without
the consent of the Holders of all of the Outstanding Securities of such series
affected thereby. (Section 508)
 
                                        8
<PAGE>   33
 
     The Indenture contains provisions entitling the Trustee, subject to the
duty during an Event of Default in respect of any series of Securities to act
with the required standard of care, to be indemnified by the Holders of the
Securities of such series before proceeding to exercise any right or power at
the request of the Holders of the Securities of such series. (Sections 601 and
603)
 
     The Indenture provides that the Trustee will, within 90 days after the
occurrence of a default in respect of any series of Securities, give to the
Holders of the Securities of such series notice of all uncured and unwaived
defaults known to it; provided, however, that, except in the case of a default
in the payment of the principal of (or premium, if any) or any interest on, or
any sinking fund or purchase fund installment with respect to, any of the
Securities of such series, the Trustee will be protected in withholding such
notice if it in good faith determines that the withholding of such notice is in
the interest of the Holders of the Securities of such series; and provided,
further, that such notice shall not be given until at least 60 days after the
occurrence of an Event of Default regarding the performance, or breach, of any
covenant or warranty of the Company other than for the payment of the principal
of (or premium, if any) or any interest on, or any sinking fund installment with
respect to, any of the Securities of such series. The term default for the
purpose of this provision only means any event that is, or after notice or lapse
of time, or both, would become, an Event of Default with respect to the
Securities of such series. (Section 602)
 
     The Indenture requires the Company to file annually with the Trustee a
certificate, executed by two officers of the Company, indicating whether the
Company is in default under the Indenture. (Section 1008)
 
MEETINGS
 
     The Indenture contains provisions for convening meetings of the Holders of
Securities of a series if Securities of that series are issuable as Bearer
Securities. (Section 1201) A meeting may be called at any time by the Trustee,
and also, upon request, by the Company or the Holders of at least 10% in
principal amount of the Outstanding Securities of such series, in any such case
upon notice given in accordance with "Notices" below. (Section 1202) Persons
entitled to vote a majority in principal amount of the Outstanding Securities of
a series shall constitute a quorum at a meeting of Holders of Securities of such
series, except that in the absence of a quorum, a meeting, called by the Company
or the Trustee shall be adjourned for a period of not less than 10 days, and in
the absence of a quorum at any such adjourned meeting, the meeting shall be
further adjourned for a period of not less than 10 days, at which further
adjourned meeting persons entitled to vote 25% in aggregate principal amount of
the Outstanding Securities of such series shall constitute a quorum. Except for
any consent which must be given by the Holder of each Outstanding Security
affected thereby, as described above under "Modification of the Indenture", and
subject to the provisions described in the last sentence under this subheading,
any resolution presented at a meeting or adjourned meeting duly reconvened at
which a quorum is present may be adopted by the affirmative vote of the lesser
of (i) the Holders of a majority in principal amount of the Outstanding
Securities of that series and (ii) 66 2/3% in aggregate principal amount of
Outstanding Securities of such series represented and voting at the meeting;
provided, however, that any resolution with respect to any request, demand,
authorization, direction, notice, consent, waiver or other action which may be
made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of Outstanding Securities of a series may
be adopted at a meeting or adjourned meeting duly reconvened at which a quorum
is present by the affirmative vote of the lesser of (i) the Holders of such
specified percentage in principal amount of the Outstanding Securities of that
series and (ii) a majority in principal amount of Outstanding Securities of such
series represented and voting at the meeting. Any resolution passed or decision
taken at any meeting of Holders of Securities of any series duly held in
accordance with the Indenture will be binding on all Holders of Securities of
that series and the related coupons. With respect to any consent, waiver or
other action which the Indenture expressly provides may be given by the Holders
of a specified percentage of Outstanding Securities of all series affected
thereby (acting as one class), only the principal amount of Outstanding
Securities of any series represented at a meeting or adjourned meeting duly
reconvened at which a quorum is present as aforesaid and voting in favor of such
action shall be counted for purposes of calculating the aggregate principal
amount of Outstanding Securities of all series affected thereby favoring such
action. (Section 1204)

NOTICES
 
     Except as otherwise provided in the Indenture, notices to Holders of Bearer
Securities will be given by publication at least once in a daily newspaper in
The City of New York and London and in such other city or cities as may be
specified in such Bearer Securities and will be mailed to such Persons whose
names and addresses were previously filed with the Trustee, within the time
prescribed for the giving of such notice. Notices to Holders of Registered
Securities will be given by mail to the address of such Holders as they appear
in the Security Register. (Section 106)
 
TITLE
 
     Title to any Bearer Security (including any Bearer Security in temporary or
definitive global bearer form) and any coupons appertaining thereto will pass by
delivery. The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security and the bearer of any coupon and the
registered owner of any Registered Security as the absolute owner thereof
(whether or not such Security or coupon shall be overdue and notwithstanding any
notice to the contrary) for the purpose of making payment and for all other
purposes. (Section 308)
 
REPLACEMENT OF SECURITIES AND COUPONS
 
     Any mutilated Security and any Security with a mutilated coupon
appertaining thereto will be replaced by the Company at the expense of the
Holder upon surrender of such mutilated Security or Security with a mutilated
coupon to the Trustee. Securities or coupons that become destroyed, stolen or
lost will be replaced by the Company at the expense of the Holder upon delivery
to the Trustee of evidence of the destruction, loss or theft thereof
satisfactory to the Company and the Trustee; in the case of any coupon which
becomes destroyed, stolen or lost, such coupon will be replaced (upon surrender
to the Trustee of the Security with all appurtenant coupons not destroyed,
stolen or lost) by issuance of a new Security in exchange for the Security to
which such coupon appertains. In the case of a destroyed, lost or stolen
Security or coupon an indemnity satisfactory to the Trustee and the Company may
be required at the expense of the Holder of such Security or coupon before a
replacement Security will be issued. (Section 306)
 
SATISFACTION AND DISCHARGE; DEFEASANCE
 
     At the request of the Company, the Indenture will cease to be in effect as
to the Company (except for certain obligations to register the transfer or
exchange of Securities and hold moneys for payment in trust) with respect to the
Securities when all such Securities have been cancelled by the Trustee, or, in
the case of Securities and coupons not delivered to the Trustee for
cancellation, (i) such Securities or coupons have become due and payable, will
become due and payable at their stated maturity within one year, or are to be
called for redemption within one year, and, in each case, the Company has
deposited with the Trustee, in trust, money, and, in the case of Securities and
coupons denominated in U.S. dollars, U.S. Government Obligations (as defined in
the Indenture) or, in the case of Securities and coupons denominated in a
foreign currency, Foreign Government Securities (as defined in the Indenture),
which through the payment of interest thereon and principal thereof in
accordance with their terms will provide money in an amount sufficient to pay in
the currency, currencies or currency units or units in which the Offered
Securities are payable all the principal of, and interest on, the Offered
Securities on the dates such payments are due in accordance with the terms of
the Offered Securities, or (ii) such Securities or coupons are deemed paid and
discharged in the manner described in the next paragraph. (Section 401)
 
     Unless the Prospectus Supplement relating to the Offered Securities
provides otherwise, 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
Offered Securities (except for certain obligations to register the transfer or
exchange of Securities, replace stolen, lost or mutilated Securities and
coupons, maintain paying agencies and hold moneys for payment in trust) or (b)
need not comply with certain restrictive covenants of the Indenture (including
those described above under "Restriction on Indebtedness"), in each case after
the Company deposits with the Trustee, in trust, money, and, in the case of
Securities and coupons denominated in U.S. dollars, U.S. Government Obligations
or,
 
                                       10
<PAGE>   35
 
in the case of Securities and coupons denominated in a foreign currency, Foreign
Government Securities, which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an amount
sufficient to pay in the currency, currencies or currency unit or units in which
the Offered Securities are payable all the principal of, and interest on, the
Offered Securities on the dates such payments are due in accordance with the
terms of the Offered Securities. Among the conditions to the Company's
exercising any such option, the Company is required to deliver to the Trustee an
opinion of counsel to the effect that the deposit and related defeasance would
not cause the Holders of the Offered Securities to recognize income, gain or
loss for United States federal income tax purposes and that the Holders will be
subject to United States federal income tax in the same amounts, in the same
manner and at the same times as would have been the case if such deposit and
related defeasance has not occurred. (Section 403)
 
     At the request of the Company, the Trustee will deliver or pay to the
Company any U.S. Government Obligations, Foreign Government Securities or money
deposited, for the purposes described in the preceding two paragraphs, with the
Trustee by the Company and which, in the opinion of a nationally-recognized firm
of independent public accountants, are in excess of the amount thereof which
would then have been required to be deposited for such purposes. In addition,
the Trustee, in exchange for, simultaneously, other U.S. Government Obligations,
Foreign Government Securities or money, will deliver or pay to the Company, at
the Company's request, U.S. Government Obligations, Foreign Government
Securities or money deposited with the Trustee for the purposes described in the
preceding two paragraphs, provided that, in the opinion of a
nationally-recognized firm of independent public accountants, immediately after
such exchange the obligations, securities or money then held by the Trustee will
be in such amount as would then have been required to be deposited with the
Trustee for such purposes. (Section 403)
 
GOVERNING LAW
 
     The Indenture, the Securities and the coupons will be governed by, and
construed in accordance with, the laws of the State of New York. (Section 113)
 
THE TRUSTEE
 
     Harris Trust and Savings Bank, Chicago, Illinois is the Trustee under the
Indenture.
 
                            DESCRIPTION OF WARRANTS
 
     The following statements with respect to the Warrants are summaries of, and
subject to, the detailed provisions of one or more separate Warrant Agreements
(each a "Warrant Agreement") between the Company and one or more banking
institutions or trust companies as Warrant Agents (each a "Warrant Agent"). A
form of Warrant Agreement will be filed as an exhibit to the Registration
Statement prior to the issuance of any Warrant.
 
GENERAL
 
     Warrants, evidenced by Warrant Certificates (the "Warrant Certificates"),
may be issued under a Warrant Agreement independently or together with any
Offered Securities and may be attached to or separate from such Offered
Securities. If Warrants are offered, the Prospectus Supplement will describe the
terms of the Warrants, including the following: (i) the offering price, if any,
including the currency, currencies or currency unit or units in which such price
will be payable; (ii) the designation, aggregate principal amount and terms of
the Offered Securities purchasable upon exercise of the Warrants; (iii) if
applicable, the designation and terms of the Offered Securities with which the
Warrants are issued and the number of Warrants issued with each such Offered
Security; (iv) if applicable, the date on and after which the Warrants and the
related Offered Securities will be separately transferable; (v) the principal
amount of Offered Securities purchasable upon exercise of one Warrant and the
price or prices at which, and the currency, currencies or currency unit or units
in which such principal amount of Offered Securities may be purchased upon
exercise; (vi) the date on which the right to exercise the Warrants shall
commence and the date on which such right shall expire; (vii) United States
Federal income tax
 
                                       11

consequences; (viii) whether the Warrants represented by the Warrant
Certificates will be issued in registered or unregistered form or both; and (ix)
any other terms of the Warrants.
 
     Warrant Certificates, if any, may be exchanged for new Warrant Certificates
of different denominations and may (if in registered form) be presented for
registration of transfer at the corporate trust office of the Warrant Agent,
which will be listed in the Prospectus Supplement, or at such other office as
may be set forth therein. Warrantholders do not have any of the rights of
Holders of Offered Securities (except to the extent that the consent of
Warrantholders may be required for certain modifications of the terms of the
Indenture) and are not entitled to payments of principal (or premium, if any),
or interest, if any, on such Offered Securities.
 
EXERCISE OF WARRANTS
 
     Warrants may be exercised by surrendering the Warrant Certificate, if any,
at the corporate trust office or other designated office of the Warrant Agent,
with the form of election to purchase on the reverse side of the Warrant
Certificate, if any, properly completed and executed, and by payment in full of
the exercise price, as set forth in the Prospectus Supplement. Upon exercise of
Warrants, the Warrant Agent will, as soon as practicable, deliver the Offered
Securities issuable upon the exercise of the Warrants in authorized
denominations in accordance with the instructions of the exercising
Warrantholder and at the sole cost and risk of such holder. If less than all of
the Warrants evidenced by the Warrant Certificate, if any, are exercised, a new
Warrant Certificate will be issued for the remaining amount of unexercised
Warrants, if sufficient time exists prior to the expiration date.
 
                  LIMITATIONS ON ISSUANCE OF BEARER SECURITIES
 
     Under U.S. federal tax laws, certain limitations on offers, sales and
delivery apply to Bearer Securities. These limitations, as well as additional
information regarding the U.S. federal income tax consequences in respect of a
Bearer Security, will be set forth in any Prospectus Supplement providing for
the issuance of Bearer Securities.
 
                             UNITED STATES TAXATION
 
     The following is a summary of the principal U.S. federal income tax
consequences of the acquisition, ownership and disposition of Registered
Securities. The summary reflects present law, which is subject to prospective
and retroactive changes. It is not intended as tax advice, and it does not
describe all of the tax considerations that may be relevant to a prospective
purchaser. The summary addresses only original purchasers of the Securities that
hold the Securities as capital assets. It does not address U.S. federal income
tax issues relevant to purchasers subject to special rules, such as banks,
securities dealers, life insurance companies, controlled foreign corporations,
persons holding Securities in connection with a hedge or persons having a
functional currency other than the U.S. dollar. The summary does not consider
the tax consequences of Securities with terms other than those described in this
Prospectus. PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISERS ABOUT
THE TAX CONSEQUENCES OF AN INVESTMENT IN THE SECURITIES UNDER THE LAWS OF THE
UNITED STATES AND OTHER JURISDICTIONS WHERE PURCHASERS ARE SUBJECT TO TAXATION.
 
     For the purposes of this discussion, "U.S. Holder" means (i) a beneficial
owner of the Securities that is a citizen or resident of the United States, a
corporation or partnership organized in or under the laws of the United States,
or an estate or trust the income of which is subject to U.S. federal income
taxation regardless of its source or (ii) any other beneficial owner as to which
income from the Securities is effectively connected with the conduct of a trade
or business within the United States. The term "Non-U.S. Holder" refers to any
beneficial owner of the Securities other than a U.S. Holder.

U.S. HOLDERS
 
     PAYMENTS OF INTEREST
 
     Interest on a Security generally will be taxable to a U.S. Holder as
ordinary interest income at the time of receipt or accrual in accordance with
the U.S. Holder's method of accounting for U.S. federal income tax purposes.
Special rules for the interest on Securities with original issue discount are
described below.
 
     ORIGINAL ISSUE DISCOUNT
 
     The following is a summary of the U.S. federal income tax consequences to
U.S. Holders of the purchase, ownership and disposition of Securities issued
with original issue discount ("OID"). The following summary is based on sections
1271 through 1273 and section 1275 of the U.S. Internal Revenue Code of 1986, as
amended (the "Code"), and on certain final regulations of the U.S. Department of
Treasury issued in 1994 (the "Final OID Regulations") interpreting these
provisions. Additionally, the summary includes a discussion of proposed
regulations issued in December 1994 relating principally to contingent payment
debt instruments issued with OID (the "Proposed OID Regulations").
 
     General.  A U.S. Holder of a Security issued at a discount with a maturity
of more than one year after the date of issue must include original issue
discount in income over the term of the Security. The U.S. Holder generally must
include in gross income for the taxable year the sum of the daily portions of
original issue discount that accrue on the Security for each day during the year
on which such holder held the Security. Accordingly, a U.S. Holder will be
required to include amounts attributable to original issue discount in income
before receiving cash attributable to that income.
 
     A Security has original issue discount for U.S. federal income tax purposes
to the extent that the Security's stated redemption price at maturity exceeds
its issue price. The issue price of a Security is the initial offering price at
which a substantial amount of the Securities is sold to the public (excluding
bond houses, brokers or similar persons). The stated redemption price of a
Security is the total of all payments due on the Security other than payments of
"qualified stated interest." A Security is not treated as issued at a discount,
however, if the discount is less than 1/4 of 1 percent of the Security's stated
redemption price at maturity multiplied by the number of complete years to
maturity ("de minimis original issue discount"). A Security that bears interest
for any accrual period at a rate below the rate for the remaining term of the
Security (e.g., a Security with a "teaser rate") also will not be treated as
issued at a discount solely on account of that feature if the foregone interest
is less than 1/4 of 1 percent of the Security's adjusted stated redemption price
multiplied by the number of complete years to maturity.
 
     Qualified stated interest is interest that is payable unconditionally in
cash or in property (other than debt of the issuer) at least annually at either
(a) a single fixed rate that appropriately takes into account the length of the
interval between payments or (b) the current values of (i) a single "qualified
floating rate," (ii) a single qualified floating rate followed by a second
qualified floating rate, (iii) a single fixed rate followed by a single
qualified floating rate or (iv) a single "objective rate" (each a "Variable
Rate"). A qualified floating rate is any floating rate the variations in which
reasonably can be expected to measure contemporaneous variations in the cost of
newly-borrowed funds (e.g., LIBOR). An objective rate is a rate, other than a
qualified floating rate, determined by a single formula that is fixed throughout
the term of the Security and is based on (i) one or more qualified floating
rates (e.g., a multiple of a qualified floating rate or the inverse of a
qualified floating rate), (ii) one or more rates each of which would be a
qualified floating rate for a Security denominated in a currency other than the
currency in which the Security is denominated, (iii) the yield or the changes in
the price of one or more items of actively traded personal property (other than
stock or debt of the Company or a related party), (iv) a combination of rates
described above in (i), (ii), or (iii), or (v) other rates designated from time
to time by the Internal Revenue Service. The Proposed OID Regulations provide
that an objective rate is any rate, other than a qualified floating rate, that
is determined using a single fixed formula and that is based on objective
financial or economic information. A rate will not be considered an objective
rate, however, if it is reasonably expected that the average value of the rate
during the first half of the Security's term will be either significantly less
than or significantly greater than the average value of the rate during the
final half of the Security's term. A fixed rate for an initial period of less
than one year followed by a qualified floating rate or an objective rate
together constitute a
 
                                       13
<PAGE>   38
 
single qualified floating objective rate if the value of the qualified floating
rate or objective rate on the issue date is intended to approximate the fixed
rate.
 
     To determine the daily portions of original issue discount, original issue
discount accruing during an accrual period is divided by the number of days in
the period. The amount of original discount accruing during an accrual period is
determined by using a constant yield to maturity method. The accrued amount for
any period is the excess of (i) the product of the Security's adjusted issue
price at the beginning of the accrual period and its yield to maturity
(determined on the basis of compounding at the close of each accrual period and
appropriately adjusted for the length of the accrual period) over (ii) the
amount of any qualified stated interest payments allocable to the accrual
period. The adjusted issue price of a Security at the beginning of any accrual
period generally equals the issue price of the Security increased by the
aggregate amount of original issue discount that accrued on that Security in all
prior accrual periods and reduced by the amount of payments in prior accrual
periods other than payments of qualified stated interest.
 
     A U.S. Holder of a Security issued at a discount that purchases the
Security for more than the Security's adjusted issue price but less than the
Security's stated redemption price at maturity may reduce the daily portions of
original issue discount includible in gross income by daily portions of the
acquisition premium paid for the Security.
 
     Variable Rate Securities.  Special rules apply to the U.S. Holder of a
Security that bears interest at a Variable Rate (a "Variable Rate Security"). In
general, to compute the accrual of OID on a Variable Rate Security, the Final
OID Regulations convert the Variable Rate Security into a fixed rate debt
instrument and then apply the general rules discussed above to the deemed fixed
rate debt instrument. If a Variable Rate Security provides for stated interest
at either a single qualified floating rate or objective rate that is
unconditionally payable at least annually, (a) all stated interest with respect
to the Variable Rate Security is treated as qualified stated interest and (b)
the amount of OID, if any, is determined under the rules applicable to fixed
rate debt instruments discussed above by assuming that the Variable Rate is a
fixed rate equal to (i) in the case of a qualified floating rate or qualified
inverse floating rate, the value, as of the issue date of the Variable Rate
Security, of the qualified floating rate or the qualified inverse floating rate,
or (ii) in the case of an objective rate (other than a qualified inverse
floating rate), a fixed rate that reflects the yield that is reasonably expected
for the Variable Rate Security.
 
     If the Variable Rate Security does not provide for stated interest as
described in the preceding paragraph, to determine the amounts of interest and
OID accruals an "equivalent fixed rate debt instrument" must be constructed. The
equivalent fixed rate debt instrument has terms that are identical to those
provided under the Variable Rate Security, except that the equivalent fixed rate
debt instrument provides for fixed rate substitutes in lieu of the qualified
floating rates or objective rate provided under the Variable Rate Security. The
fixed rate substitute (a) for each qualified floating rate is the value of each
such rate as of the issue date of the Variable Rate Security (with appropriate
adjustment for any differences in intervals between interest adjustment dates),
(b) for a qualified inverse floating rate is the value of the qualified inverse
floating rate as of the issue date of the Variable Rate Security and (c) for an
objective rate (other than a qualified inverse floating rate) is a fixed rate
that reflects the yield that is reasonably expected for the Variable Rate
Security. The amounts of qualified stated interest and OID, if any, are
determined for the equivalent fixed rate debt instrument under the rules
applicable to fixed rate debt instruments as described above and are taken into
account as if the holder of the Security held the equivalent fixed rate debt
instrument. Qualified stated interest or OID allocable to an accrual period is
increased (or decreased) if the interest actually accrued or paid during an
accrual period exceeds (or is less than) the interest assumed to be accrued or
paid during the accrual period under the equivalent fixed rate debt instrument.
This increase or decrease is an adjustment to qualified stated interest of the
accrual period if the equivalent fixed rate debt instrument provides for
qualified stated interest and the increase or decrease is reflected in the
amount actually paid during the accrual period. Otherwise, this increase or
decrease is an adjustment to OID for the accrual period. If the Variable Rate
Security provides for interest at a qualified floating rate or qualified inverse
floating rate and also provides for stated interest at a single fixed rate
(other than a single fixed rate for an initial period of less than one year that
is intended to approximate the value of the qualified floating or objective
rate), in constructing the equivalent fixed rate debt instrument, such a
Variable Rate Security is treated as if it provided for a qualified floating
rate (or qualified inverse floating rate, as the case may be) instead of the
fixed rate, which qualified floating (or inverse floating) rate is such that the
Variable Rate Security would have the same fair market
 
                                       14
<PAGE>   39
 
value as of its issue date. The foregoing rules do not apply, and a Security is
treated as a Contingent Payment Security (defined below), if its issue price
exceeds the total of noncontingent principal payments by more than the lesser of
(i) the product of .015, the total noncontingent principal payments and the
number of complete years to maturity (or a lesser amount if principal is payable
in installments) and (ii) 15 percent of the total noncontingent principal
payments.
 
     Optional Redemption.  For purposes of determining the yield of a Security,
the Company will be presumed to exercise any right to redeem a Security before
its stated maturity or to extend the maturity of a Security if exercise would
reduce the yield on the Security. Likewise, the holder will be presumed to
exercise any right to require the redemption of a Security or to extend the
maturity of the Security if exercise would increase the yield on the Security.
If the Security is not actually redeemed on the date when the option was
presumed to have been exercised, the Security will be treated only for purposes
of determining yield as having been reissued at a price equal to that Security's
adjusted issue price on that date with a term based on the original final
maturity of the Security.
 
     Short-Term Securities.  U.S. Holders that do not use the accrual method of
accounting for tax purposes generally will not be required to recognize original
issue discount on Securities maturing within one year of original issuance until
they receive payments on the Securities. Taxpayers on the accrual method,
regulated investment companies, common trust funds, and certain others, however,
must accrue original issue discount on such short-term Securities on a
straight-line basis unless they elect to accrue the discount on a constant yield
basis with daily compounding. The original issue discount on a short-term
Security is the amount by which the total principal and interest payments on the
Security exceed its issue price. U.S. Holders may elect to include discount on
such short-term Securities into income based on acquisition discount rather than
original issue discount. Acquisition discount is the excess of a Security's
stated redemption price at maturity over the U.S. Holder's basis in the
Security.
 
     Gain recognized on the sale or exchange of a short-term Security by a U.S.
Holder that has not accrued discount on the Security will be ordinary income to
the extent attributable to accrued interest and original issue discount. Such a
holder also must defer deductions for net interest expense on any borrowing
attributable to the short-term Security to the extent that the expense does not
exceed accrued but unrecognized interest and original issue discount (or
acquisition discount) on the Security.
 
     ANTI-ABUSE RULE
 
     The Internal Revenue Service can apply or depart from the rules contained
in the Final OID Regulations as necessary or appropriate to achieve a reasonable
result where a principal purpose in structuring a Security or applying the
otherwise applicable rules is to achieve a result that is unreasonable in light
of the purposes of the applicable statutes (which generally are intended to
achieve the clear reflection of income for both sellers and purchasers of the
Securities).
 
     MARKET DISCOUNT
 
     A U.S. Holder that purchases a Security at a market discount generally will
be required to treat payments other than qualified stated interest payments as
ordinary income to the extent of the accrued market discount and to treat gain
on the sale of the Security as ordinary income to the extent of the accrued
market discount not previously included in income. See "Sale or Exchange of
Securities" below. Market discount is the amount by which the stated redemption
price at maturity (or, in the case of a Security with original issue discount,
the revised issue price) exceeds the purchaser's basis in the Security
immediately after acquisition. A Security is not treated as purchased at a
market discount, however, if the discount is less than 1/4 of 1 percent of the
stated redemption price at maturity (or the revised issue price) multiplied by
the number of complete years remaining to maturity ("de minimis market
discount"). (The revised issue price of a Security is its initial issue price
increased by the amount of original issue discount includible in the gross
income of previous holders.) Market discount on a Security will accrue, at the
election of the holder, either ratably or at a constant yield to maturity. The
U.S. Holder may elect to take market discount into income as it accrues. Under
certain circumstances, the
 
                                       15
<PAGE>   40
 
U.S. Holder may be required to defer deductions for interest expense
attributable to debt incurred or continued to purchase a Security with market
discount.
 
     PREMIUM
 
     A U.S. Holder that purchases a Security for more than its stated redemption
price at maturity may elect to amortize the bond premium. If a U.S. Holder makes
such an election, the amount of interest on the Security otherwise to be
included in the U.S. Holder's income will be reduced each year by the amount of
amortizable bond premium allocable to such year on a constant yield to maturity
basis (except to the extent regulations may provide otherwise). Amortized bond
premium will reduce the U.S. Holder's basis in the Security. An election to
amortize bond premium will apply to certain other debt instruments that the U.S.
Holder acquired at a premium, and the election may have different tax
consequences depending on when the debt instruments were issued or acquired. It
also is not entirely clear how amortizable bond premium would be computed for
obligations with contingent interest payments. A U.S. Holder should consult its
tax adviser before making an election to amortize bond premium.
 
     INTEREST ELECTION
 
     A U.S. Holder may elect, in the taxable year in which the U.S. Holder
acquires a Security, to treat all interest on any Security as OID and calculate
the amount includible in gross income under the constant yield method described
above. For purposes of this election, interest includes stated interest,
acquisition discount, OID, de minimis OID, market discount, de minimis market
discount and unstated interest, as adjusted by any amortizable bond premium or
acquisition premium. If a U.S. Holder makes this election for a Security with
market discount or amortizable bond premium, the election is treated as an
election under the market discount or amortizable bond premium provisions,
described above, and the electing U.S. Holder will be required to amortize bond
premium or include market discount in income currently for all of its other debt
instruments with market discount or amortizable bond premium acquired during
such tax year and in any subsequent tax year. The election, once made, may not
be revoked without the consent of the Internal Revenue Service. U.S. Holders
should consult with their own tax advisers before making this election.
 
     SALE OR EXCHANGE OF SECURITIES
 
     Except to the extent that gain or loss is attributable to accrued but
unpaid interest or accrued market discount, a U.S. Holder generally will
recognize capital gain or loss upon a sale, exchange or complete retirement of a
Security equal to the difference between the amount realized and the U.S.
Holder's adjusted basis in the Security. The gain or loss will be long-term if
the Security has been held for more than one year. The adjusted basis of a
Security generally will equal its initial cost increased by any original issue
discount, market discount or acquisition discount with respect to the Security
previously included in the U.S. Holder's gross income and reduced by the
payments previously received on the Security, other than payments of qualified
stated interest, and by any amortized premium.
 
     The tax consequences of the partial redemption of a Security will depend
upon the price at which the U.S. Holder purchased the Security. A U.S. Holder
that purchased a Security at a de minimis market discount or purchased a
Security for more than its revised issue price, but less than its principal
amount, will recognize capital gain equal to the difference between the
principal prepayment and the U.S. Holder's adjusted basis in the prepaid portion
of the Security. If a U.S. Holder purchased a Security at a market discount, (i)
the principal prepayment will be included in ordinary income to the extent of
the accrued market discount (and it is possible that amounts allocable to
unaccrued market discount will be recognized as capital gain) and (ii) any
principal prepayment exceeding the revised issue price allocable to the prepaid
portion of the Security will be capital gain. If a U.S. Holder purchased a
Security for more than its stated principal amount and has not elected to
amortize bond premium, the U.S. Holder will recognize a capital loss equal to
any amount by which the U.S. Holder's adjusted basis in the prepaid portion of
the Security exceeds the amount of the principal prepayment. If the U.S. Holder
has elected to amortize bond premium, all or part of such excess might be
deductible as amortizable bond premium rather than as capital loss. Any capital
gain or loss will be long-term if the Security has been held for more than one
year. It is possible that capital gain realized by holders of one or more
classes of Securities could be considered
 
                                       16
<PAGE>   41
 
gain realized upon the disposition of property that was part of a "conversion
transaction." A "conversion transaction" is any transaction in which
substantially all of the expected return is attributable to the time value of
the U.S. Holder's net investment, if (i) the U.S. Holder entered the contract to
sell the Security substantially contemporaneously with acquiring the Security,
(ii) the Security is part of a straddle, (iii) the Security is marketed or sold
as producing capital gains, or (iv) the transaction is specified in Treasury
regulations that have not yet been issued. If the sale or other disposition of
the Security is part of a conversion transaction, all or any portion of the gain
realized upon the sale or other disposition of the Securities would be treated
as ordinary income instead of capital gain.
 
FOREIGN CURRENCY SECURITIES
 
     The tax treatment of Securities the interest or principal on which may be
determined by reference to one or more foreign currencies will depend on the
application of special rules to the particular terms of the Securities. The tax
considerations relevant to such Securities will be described in an applicable
Prospectus Supplement, and each prospective purchaser should consult its tax
adviser about such matters.
 
CONTINGENT PAYMENT SECURITIES
 
     The Proposed OID Regulations contain special rules for determining the
timing and amount of OID to be accrued in respect of Securities providing for
one or more contingent payments ("Contingent Payment Securities"). For this
purpose, a Security is not a Contingent Payment Security if it (i) is a Variable
Rate Security, (ii) provides for alternate payment schedules upon the occurrence
of contingencies or (iii) is a foreign currency debt instrument. Under the
Proposed OID Regulations, U.S. Holders generally would be required to take
contingent interest payments on Contingent Payment Securities into income on a
yield to maturity basis in accordance with a schedule of projected payments
provided by the Company to U.S. Holders and would make annual adjustments to
income to account for the difference between actual payments received and
projected payment amounts accrued. The Proposed OID Regulations have a
prospective effective date and would not apply to a Security issued at any time
prior to sixty days after the regulations are published in final form.
Additional disclosure will be provided for in a Prospectus Supplement in
connection with any offering of Contingent Payment Securities. Prospective
purchasers should consult their own tax advisers regarding the Proposed OID
Regulations in connection with ownership of a Security that provides for
contingent payments.
 
NON-U.S. HOLDERS
 
     Interest received by a Non-U.S. Holder is exempt from U.S. federal income
tax unless the holder actually or constructively owns at least 10% of the total
combined voting power of the Company's stock or the holder is for U.S. income
tax purposes a controlled foreign corporation related to the Company through
stock ownership. However, "contingent interest" paid to a Non-U.S. Holder will
be subject to a 30% tax (unless an applicable tax treaty eliminates or reduces
the rate of the tax and the Non-U.S. Holder complies with the requirements for
obtaining that reduction or elimination of the tax). For this purpose,
contingent interest is an amount of interest determined by reference to (i)
receipts, sales, or other cash flows of the Company or a related person, (ii)
income or profits of the Company or a related person, (iii) any change in the
value of any property of the Company or a related person, or (iv) any dividend,
partnership distribution, or similar payment made by the Company or a related
person. To qualify for that exemption, a Non-U.S. Holder must provide a
statement signed under penalties of perjury certifying that the holder is not a
U.S. person for U.S. tax purposes and providing the holder's name and address.
The Internal Revenue Service currently is considering modifications to the
certification procedures required to qualify for the exemption. Gain from the
sale or other disposition of a Security by a Non-U.S. Holder is not subject to
U.S. federal income tax unless the Non-U.S. Holder is an individual who is
present in the United States for at least 183 days during the taxable year of
the disposition and certain other conditions are met.
 
     Securities held by a Non-U.S. Holder will not be subject to the U.S.
federal estate tax unless the holder actually or constructively owns at least
10% of the total combined voting power of the Company's stock.

INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     A 31% backup withholding of federal income tax and certain information
reporting requirements may apply to certain payments made on the Securities and
to the proceeds from the disposition of a Security if the holder is not a
corporation, a financial institution or otherwise entitled to an exemption. U.S.
Holders that provide a correct taxpayer identification number and Non-U.S.
Holders that provide the statement described above to establish an exemption
from withholding tax generally are exempt from backup withholding. Amounts
withheld under the backup withholding rules can be claimed as a refund or taken
as a credit against the holder's U.S. federal income tax liability on a properly
filed annual income tax return.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Securities and/or Warrants being offered hereby
(i) directly to purchasers, (ii) through agents or (iii) through underwriters or
a group of underwriters which may include Lehman Brothers Inc. and/or Merrill
Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated.
 
     Offers to purchase Offered Securities and/or Warrants may be solicited
directly by the Company or by agents designated by the Company from time to

will be acting on a best-efforts basis for the period of its appointment. Agents
may be entitled under agreements which may be entered into with the Company to
indemnification by the Company against certain civil liabilities, including
liabilities under the Securities Act of 1933, as amended (the "Act").
 
     If an underwriter or underwriters are utilized in the sale, the Company
will enter into an underwriting agreement with such underwriters at the time of
sale to them and the names of the underwriters and the terms of the transaction
will be set forth in the Supplement, which will be used by the underwriters to
make resales of the Offered Securities and/or Warrants in respect of which this
Prospectus is delivered to the public. The underwriters may be entitled, under
the underwriting agreement, to indemnification by the Company against certain
liabilities, including liabilities under the Act.
 
     The agents and underwriters may be deemed to be underwriters and any
discounts, commissions or concessions received by them from the Company or any
profit on the resale of Offered Securities and/or Warrants by them may be deemed
to be underwriting discounts and commissions under the Act. Any such person who
may be deemed to be an underwriter and any such compensation received from the
Company will be described in the Prospectus Supplement.
 
     If so indicated in the Prospectus Supplement, the Company will authorize
agents and underwriters to solicit offers by certain institutions to purchase
Offered Securities and/or Warrants from the Company at the public offering price
set forth in the Prospectus Supplement pursuant to delayed delivery contracts
("Contracts") providing for payment and delivery on the date stated in the
Prospectus Supplement. Each Contract will be for an amount not less than, and

than, the respective amounts stated in the Prospectus Supplement. Institutions
with whom Contracts, when authorized, may be made include commercial and savings
banks, insurance companies, pension funds, investment companies, educational and
charitable institutions, and other institutions, but will in all cases be
subject to the approval of the Company. Contracts will not be subject to any
conditions except that the purchase by an institution of the Offered Securities
and/or Warrants covered by its Contract shall not at the time of delivery be
prohibited under the laws of any jurisdiction in the United States to which such
institution is subject. A commission indicated in the Prospectus Supplement will
be granted to agents and underwriters soliciting purchases of Offered Securities
pursuant to Contract accepted by the Company. Agents and underwriters will have
no responsibility in respect of the delivery or performance of Contracts.
 
     The place and time of delivery for the Offered Securities and Warrants in
respect of which this Prospectus is delivered are set forth in the Supplement.
 
     Each underwriter, dealer and agent participating in the distribution of any
Offered Securities which are issuable in bearer form will agree that it will not
offer, sell or deliver, directly or indirectly, Offered Securities in
 
                                       18

Prospectus and any Prospectus Supplement or any other offering material relating
to the Offered Securities may not be distributed in or from Great Britain other
than to persons whose business involves the acquisition and disposal, or the

established trading market. Any underwriters to whom Offered Securities are sold
by the Company for public offering and sale may make a market in such Offered
Securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
