                                SUMMARY OF TERMS
 
This summary highlights selected information from this document and does not
contain all of the information that you need to consider in making your
investment decision. To understand all of the terms of an offering of the notes,
you should read carefully this entire document, the applicable pricing
supplement(s), and the prospectus.
 
MBNA CORPORATION
 
MBNA Corporation is a bank holding company organized under the laws of Maryland
in 1990. It is registered under the Bank Holding Company Act of 1956, as
amended.
 
MBNA Corporation generates interest and other income through:
 
- -  finance charges on loans;
- -  interchange income;
- -  credit card and other fees;
- -  securitization income; and
- -  interest earned on investments.
 
MBNA Corporation's primary costs are:
 
- -  interest paid on deposits and borrowed funds;
- -  credit losses;
- -  royalties paid for endorsements;
- -  business development;
- -  operating expenses; and
- -  income taxes.
 
The largest operating subsidiary of MBNA Corporation is MBNA America Bank,
National Association.
 
DESCRIPTION OF THE NOTES
 
The maximum principal amount of notes that can be issued is $2.25 billion or
their equivalent value in foreign currencies. This amount may be reduced as a
result of the issuance of other securities under the accompanying prospectus.
 
We will issue the notes under:
 
- -  a senior indenture between us and Bankers Trust as trustee for the senior
   notes and
- -  a subordinated indenture between us and Harris Trust and Savings Bank as
   trustee for the subordinated notes.
 
This prospectus supplement briefly outlines some of these indentures'
provisions. If you would like more information on these provisions, you may
review the indentures that we filed with the SEC.
 
Neither indenture limits the amount of notes that may be issued. Each series of
notes may have different terms.
 
At June 30, 1998, the total amount of Senior Indebtedness outstanding was
approximately $1.9 billion and the total principal amount of all other
indebtedness of MBNA Corporation outstanding was approximately $566.3 million.
 
The senior notes are unsecured and will rank equally with all our unsecured
indebtedness unless otherwise indicated in an applicable pricing supplement.
 
The notes will be denominated in U.S. dollars or their equivalent value in
foreign currencies and we will pay principal and interest in U.S. dollars or the
appropriate foreign currency.
 
The notes will not be subject to any conversion, amortization, or sinking fund,
unless otherwise specified.
 
It is anticipated that the notes will be "book-entry," represented by a
permanent global note registered in the name of The Depository Trust Company, or
its nominee. However, we reserve the right to issue notes in certificated form,
registered in the name of the noteholders.
 
In the discussion that follows, whenever we talk about paying principal on the
notes, we mean at maturity, redemption or repurchase. Also, in discussing the
time for notices and how the different interest rates are calculated, all times
are New York City time, unless otherwise noted.
 
The pricing supplement for each offering of the notes will contain the specific
information and terms for that offering. The following items may apply to each
note as specified in the applicable pricing supplement and the note.
 
PAYMENT OF PRINCIPAL AND INTEREST
 
Payments of principal, premium (if any) and interest will be made in U.S.
dollars, except for notes not denominated in U.S. dollars.
 
                                       S-5
<PAGE>   6
 
Payments on book-entry notes will be made to The Depository Trust Company or its
nominee. Payments on certificated notes will be made by check in U.S. dollars or
by wire by contacting the trustee by the record date. In addition, anyone
holding $10 million or more principal amount of notes can request that payment
of principal and interest be wired to them by contacting the trustee by the
record date.
 
See "Description of Notes--Payment of Principal and Interest" in this prospectus
supplement for a discussion of payments for notes not denominated in U.S.
dollars.
 
The interest rate on the notes will either be fixed or floating. The interest
paid will include interest accrued to, but excluding, the date of maturity,
redemption or repurchase.
 
See "Description of Notes--Payment of Principal and Interest" in this prospectus
supplement.
 
BUSINESS DAYS
 
Generally, the term business day is any weekday on which banks are open. We will
determine and reset interest rates and pay interest on business days. The
business days applicable to your notes depend on the interest rate index and the
currency on which your notes are based. For example, if your notes are based in
deutsche marks, business days are weekdays on which banks are open in both
Germany and the United States.
 
See "Description of Notes--General" in this prospectus supplement for a full
description of business days.
 
FIXED RATE NOTES
 
We Pay Interest on Fixed Rate Notes on Two Business Days per Year
 
Unless we state otherwise in the pricing supplement, we will pay interest on
February 15 and August 15, provided these are business days. Whenever one of
these dates falls on a day other than a business day, we will pay interest on
the next business day but we will not pay additional interest. To compute the
amount of interest, we will use a hypothetical 360-day year of twelve 30-day
months.
 
Other Events in Which We Pay Interest
 
We will also pay interest on a note when it matures, is redeemed, or is
purchased. If any of these events occurs on a day other than a business day, we
will pay interest on the next business day but we will not pay additional
interest.
 
Interest Rates
 
The pricing supplement will provide the interest rate for your notes.
 
See "Description of Notes--Fixed Rate Notes--General" in this prospectus
supplement.
 
FLOATING RATE NOTES
 
The pricing supplement for each floating rate note will provide an interest rate
formula. The formula may be based on:
 
- -  the commercial paper rate;
- -  the federal funds effective rate;
- -  the CD rate;
- -  LIBOR;
- -  the prime rate;
- -  the Treasury rate; or
- -  another interest rate index.
 
Each pricing supplement will also indicate the Spread and/or Spread Multiplier,
if any, and any maximum or minimum interest rate limitations.
 
Upon request, the calculation agent will provide you with the current interest
rate and, if different, the interest rate which will become effective on the
next date that the interest rate is reset.
 
When Interest Rates Are Determined
 
The calculation agent will determine interest rates for all floating rate notes
except Treasury rate notes and LIBOR notes on the second business day before the
date that the interest rate is reset.
 
Special Considerations for Treasury Rate Notes
The calculation agent will determine interest rates for Treasury rate notes on
the day of the week in which interest is reset on which Treasury bills would
normally be auctioned.
 
                                       S-6
<PAGE>   7
 
Special Considerations for LIBOR Notes
Generally speaking, a business day for LIBOR notes is any weekday on which banks
are open in both New York City and London. The calculation agent will determine
interest rates for LIBOR notes two business days before the date that the
interest rate is reset.
 
See "Description of Notes--Floating Rate Notes--General" in this prospectus
supplement.
 
When Interest Rates Are Reset
 
Interest rates for all floating rate notes are reset as follows, unless we state
otherwise in a pricing supplement:
 
- -  for notes that reset daily, each business day;
- -  for notes other than Treasury rate notes that reset weekly, Wednesday of each
   week;
- -  for Treasury rate notes that reset weekly, Tuesday of each week;
- -  for notes that reset monthly, the third Wednesday of each month;
- -  for notes that reset quarterly, the third Wednesday of March, June, September
   and December;
- -  for notes that reset semi-annually, the third Wednesday of the two months
   stated in the pricing supplement; and
- -  for notes that reset annually, the third Wednesday of the month stated in the
   pricing supplement.
 
When Interest Is Paid
 
Interest on the floating rate notes is paid as follows, unless we state
otherwise in a pricing supplement:
 
- -  for 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;
- -  for notes which reset quarterly, on the third Wednesday of March, June,
   September, and December
- -  for notes which reset semi-annually, on the third Wednesday of the two months
   stated in the pricing supplement;
- -  for notes which reset annually, on the third Wednesday of the month stated in
   the pricing supplement; and
- -  at maturity, redemption or repurchase.
 
The record date for floating rate notes will be 15 calendar days prior to each
day interest is paid, whether or not such day is a business day.
 
The interest payable will be the amount of interest accrued to, but excluding,
the interest payment date. However, for floating rate notes on which the
interest resets daily or weekly, the interest payable will include interest
accrued to and including the record date prior to the interest payment date.
 
Commercial Paper Rate Notes
 
Each commercial paper rate note will bear interest at the interest rate stated
in the pricing supplement.
 
"Commercial Paper Rate" means the Money Market Yield of the rate for commercial
paper having the same maturity stated in the pricing supplement for any day that
the interest rate on a commercial paper rate note is to be determined. This rate
will be published by the Board of Governors of the Federal Reserve System in
H.15(519) under the heading "Commercial Paper--Nonfinancial."
 
In addition, see "Description of Notes--Floating Rate Notes--Commercial Paper
Rate Notes" in this prospectus supplement for a discussion of the determination
of the Commercial Paper Rate if that rate does not appear in H.15(519).
 
Federal Funds Effective Rate Notes
 
Each federal funds effective rate note will bear interest at the rate stated in
the pricing supplement.
 
"Federal Funds Effective Rate" means the rate for Federal Funds having the same
maturity stated in the pricing supplement for any day that the interest rate on
a federal funds effective rate note is to be determined. This rate will be
published by the Board of Governors of the Federal Reserve System in H.15(519)
under the heading "Federal Funds (Effective)."
 
In addition, see "Description of Notes--Floating Rate Notes--Federal Funds
Effective Rate Notes" in this prospectus supplement for a discussion of the
determination of the Federal Funds Effective Rate if that rate does not appear
in H.15(519).

<PAGE>   8
 
CD Rate Notes
 
Each CD rate note will bear interest at the rate stated in the pricing
supplement.
 
"CD Rate" means the rate for negotiable certificates of deposit having the same
maturity stated in the pricing supplement for any day that the interest rate on
a CD rate note is to be determined. This rate will be published by the Board of
Governors of the Federal Reserve System in H.15(519) under the heading "CDs
(Secondary Market)."
 
In addition, see "Description of Notes--Floating Rate Notes--CD Rate Notes" in
this prospectus supplement for a discussion of the determination of the CD Rate
if that rate does not appear in H.15(519).
 
LIBOR Notes
 
Each LIBOR note will bear interest at the rate stated in the pricing supplement.
 
LIBOR will be determined by the calculation agent by reference to either a
Reuters or Telerate page.
 
In addition, see "Description of Notes--Floating Rate Notes--LIBOR Notes" in
this prospectus supplement.
 
Prime Rate Notes
 
Each prime rate note will bear interest at the rate stated in the pricing
supplement.
 
"Prime Rate" means the rate published by the Board of Governors of the Federal
Reserve System in H.15(519) under the heading "Bank Prime Loan" for any day that
the interest rate for a prime rate note is to be determined.
 
In addition, see "Description of Notes--Floating Rate Notes--Prime Rate Notes"
in this prospectus supplement for a discussion of the determination of the
Federal Funds Effective Rate if that rate does not appear in H.15(519).
 
Treasury Rate Notes
 
Each Treasury rate note will bear interest at the rate stated in the pricing
supplement.
 
"Treasury Rate" means the rate for United States "Treasury bills" having the
same maturity stated in the pricing supplement for any day that the interest
rate for a Treasury rate note is to be determined. This rate will be published
by the Board of Governors of the Federal Reserve System in H.15(519) under the
heading "U.S. Government Securities/Treasury bills auction average
(investment)."
 
In addition, see "Description of Notes--Floating Rate Notes--Treasury Rate
Notes" in this prospectus supplement for a discussion of the determination of
the Treasury Rate if that rate does not appear in H.15(519).

REDEMPTION AND REPAYMENT
 
We may redeem notes at our option. Notes may be redeemable in whole or in part
upon no more than 60, and no less than 30, days' prior notice. If we do not
redeem all the notes of a series at one time, the trustee selects the notes to
be redeemed in a manner it determines to be fair.
 
We may offer notes that give you the option to be repaid prior to the maturity
of your notes.

COMBINATIONS OF PROVISIONS
 
Any note may utilize all, or any combination, of the provisions described in the
following sections of the prospectus supplement:
 
- -  Interest Rate Reset;
- -  Extension of Maturity;
- -  Renewable Notes; and

REPURCHASE
 
We may, at any time, purchase notes at any price. Notes purchased by us may be
held or resold, or may be surrendered to the trustee for cancellation.
 
BOOK-ENTRY NOTES
 
Book-entry notes of a series will be issued in the form of a global note that
will be deposited with The Depository Trust Company. This means that we will not
issue certificates to each holder.
 
Beneficial interests in global notes will be shown on, and transfers of global
notes will be made only through, records maintained by The Depository Trust
Company and its participants.
 
Notes represented by a global note will be exchangeable for certificated notes
with the same terms in authorized denominations only if:

- -  The Depository Trust Company notifies us that it is unwilling or unable to
   continue as depository or if The Depository Trust Company ceases to be a
   clearing agency registered under applicable law;
- -  we determine not to require all of the notes of a series to be represented by
   a global note and notify the trustee of our decision; or
- -  an event of default has occurred and is continuing which would constitute an
   event of default with respect to the notes.

                                  THE COMPANY
 
     MBNA Corporation (the "Company") is a registered bank holding company
incorporated under the laws of Maryland in 1990. It is the parent corporation of
MBNA America Bank, National Association (the "Bank"), a national bank organized
in January 1991, as the successor to a national bank organized in 1982.
 
     The Company generates interest and other income through finance charges
assessed on outstanding loan receivables, interchange income, credit card and
other fees, securitization income, and interest earned on investment securities
and money market instruments. The Company's primary costs are the costs of
funding its loan receivables and investment securities, which include interest
paid on deposits, short-term borrowings, and long-term debt and bank notes;
credit losses; royalties paid to affinity groups and financial institutions;
business development and operating expenses; and income taxes.
 
                              DESCRIPTION OF NOTES
 
     The following description of the particular terms of the Senior Medium-Term
Notes, Series D (the "Senior Notes") and Subordinated Medium-Term Notes, Series
D (the "Subordinated Notes" and, together with the Senior Notes, the "Notes")
offered hereby supplements, and to the extent inconsistent therewith replaces,
the description of the general terms and provisions of the Debt Securities, the
Senior Indenture and the Subordinated Indenture described in the accompanying
Prospectus, to which description reference is hereby made. The following
description of the Notes will apply to each Note unless otherwise specified in
the applicable pricing supplement (each, a "Pricing Supplement"). Capitalized
terms used below that are not defined herein have the meanings specified in the
accompanying Prospectus or in the Senior Indenture or the Subordinated
Indenture, as appropriate.
 
GENERAL
 
     The Notes will be limited in aggregate principal amount to $2,250,000,000,
or the equivalent thereof in foreign currencies or currency units (each, a
"Specified Currency"), subject to reduction under certain circumstances as a
result of the sale of other Securities of the Company under the accompanying
Prospectus. The Company may from time to time authorize an increase in the
aggregate principal amount of Notes to be sold, which Notes will constitute a
part of the same two series as the Notes offered hereby. In the case of Original
Issue Discount Notes (as defined below), such limit will be determined by
reference to the aggregate gross proceeds to the Company. The Notes will be
either Senior Debt Securities or Subordinated Debt Securities of the Company, as
set forth in the applicable Pricing Supplement. The Senior Notes, which will
constitute a single series of Senior Debt Securities, and the Subordinated
Notes, which will constitute a single series of Subordinated Debt Securities,
will be issued under a Senior Indenture and a Subordinated Indenture,
respectively (each, an "Indenture"), which are more fully described in the
accompanying Prospectus. The Trustee for the Senior Notes is Bankers Trust
Company and the Trustee for the Subordinated Notes is Harris Trust and Savings
Bank. The following summaries of certain provisions of the Senior Indenture and
the Subordinated Indenture do not purport to be complete, and are subject to,
and qualified in their entirety by reference to, all of the provisions of each
such Indenture.
 
     The Indentures do not limit the aggregate principal amount of Debt
Securities that may be issued thereunder and provide that Debt Securities may be
issued in one or more series up to the aggregate principal amount that may be
authorized from time to time by the Company.
 
     The Senior Notes will rank on a parity with all other unsecured and
unsubordinated obligations of the Company. The Subordinated Notes will be
unsecured and will be subordinated in right of payment to the prior payment in
full of all Senior Indebtedness and Other Financial Obligations of the Company.
There is no limitation on the amount of other indebtedness, including Senior
Indebtedness, that may be issued by the Company or any of its Subsidiaries. At
June 30, 1998, the aggregate principal amount of Senior Indebtedness outstanding
was approximately $1.9 billion and the aggregate principal amount of all other
indebtedness of the Company outstanding was approximately $566.3 million. The
Company expects from time to time to incur additional indebtedness constituting
Senior Indebtedness and Other Financial Obligations.
 
                                      S-10
<PAGE>   11
 
     The Notes will be offered on a continuing basis and each Note will mature
nine months or more from its date of issue, as selected by the initial purchaser
and agreed to by the Company, and may be subject to redemption at the option of
the Company or repayment at the option of the Holder prior to Stated Maturity
(as defined below) as described under "-- Redemption and Repayment." Each Note
will be denominated in U.S. dollars or in such other Specified Currency as is
indicated in the applicable Pricing Supplement. Each Note will either bear
interest at (i) a fixed rate (a "Fixed Rate Note"), which may bear interest at a
rate of zero in the case of a Note issued at an Issue Price (as defined below)
representing a discount from the principal amount payable at Stated Maturity (a
"Zero-Coupon Note"), or (ii) a floating rate (a "Floating Rate Note"), which
will bear interest at a rate determined by reference to the interest rate basis
or combination of interest rate bases (the "Base Rate") indicated in the
applicable Pricing Supplement, which may be adjusted by a Spread and/or Spread
Multiplier (each as defined below).
 
     Each Note will be issued initially as either in book-entry form (each, a
"Book-Entry Note") or in fully registered, certificated form without coupons
(each, a "Certificated Note"). Except as set forth below under "-- Book-Entry
Notes," Book-Entry Notes will not be issuable in certificated form.
 
     Unless otherwise specified in an applicable Pricing Supplement, Notes
denominated in U.S. dollars will be issuable in denominations of $100,000 and
integral multiples of $1,000 in excess thereof. Notes denominated in a Specified
Currency other than U.S. dollars will be issued in authorized denominations that
are equivalent, at the 11:00 A.M. buying rate in the City of New York for cable
transfers in such Specified Currency as certified for customs purposes by the
Federal Reserve Bank of New York (the "Market Exchange Rate") on the first
Business Day in the City of New York and the country issuing such currency (or,
in the case of European Currency Units ("ECUs"), Brussels) next preceding the
date on which the Company accepts the offer to purchase such Note, to $100,000
(rounded down to an integral multiple of 10,000 units of such Specified
Currency) and integral multiples of 10,000 units of such Specified Currency in
excess thereof. If any of the Notes are to be denominated in a Specified
Currency other than U.S. dollars, or if the principal of and any premium or
interest on any of the Notes not denominated in U.S. dollars is to be payable at
the option of the Holder or the Company in U.S. dollars, the applicable Pricing
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.
 
     "Business Day" means, with respect to any particular location, each Monday,
Tuesday, Wednesday, Thursday and Friday which is not a day on which banking
institutions in such location are authorized or obligated by law or executive
order to close. "Market Day" means with respect to any Note, other than any
LIBOR Note, any Business Day in the City of New York and, with respect to any
LIBOR Note, any Business Day in the City of New York which is also a London
Market Day. "London Market Day" means any day in which dealings in deposits in
U.S. dollars are transacted in the London interbank market. "Index Maturity"
means, with respect to a Floating Rate Note, the period to maturity of the
instrument or obligation on which the interest rate formula is based, as
indicated in the applicable Pricing Supplement.
 
     "Original Issue Discount Note" means a Note, including any Zero-Coupon
Note, that has a stated redemption price at maturity that exceeds its Issue
Price by at least 0.25% of its principal amount multiplied by the number of full
years from the Original Issue Date (as defined below) to the Stated Maturity for
such Note. See "Certain United States Federal Income Tax Consequences --
Original Issue Discount" in this Prospectus Supplement.
 
     The Pricing Supplement relating to each Note will describe the following
terms: (i) whether such Note is a Senior Note or a Subordinated Note; (ii) the
Specified Currency with respect to such Note (and, if such Specified Currency is
other than U.S. dollars, certain other terms relating to such Note, including
authorized denominations); (iii) the price (expressed as a percentage of the
aggregate principal amount thereof) at which such Note will be issued (the
"Issue Price"); (iv) the date on which such Note will be issued (the "Original
Issue Date"); (v) the date on which such Note will mature (the "Stated
Maturity") and whether the Stated Maturity may be extended by the Company and,
if so, the Extension Period and the Final Maturity Date (each as defined below);
(vi) whether such Note is a Fixed Rate Note or a Floating Rate Note; (vii) if
such Note is a Fixed Rate Note, whether such Note is an Amortizing Note (as
defined below); (viii) if such
 
                                      S-11
<PAGE>   12
 
Note is a Fixed Rate Note, the rate per annum at which such Note will bear
interest, if any, any Interest Payment Date or Dates (as defined below) and, if
so specified in the applicable Pricing Supplement, that such rate may be changed
by the Company prior to the Stated Maturity and, if so, the basis or formula for
such change, if any; (ix) if such Note is a Floating Rate Note, the Base Rate,
the initial interest rate (the "Initial Interest Rate"), the Reset Period (as
defined below), the Interest Payment Dates, the maximum interest rate, if any,
the minimum interest rate, if any, the Spread, if any, the Spread Multiplier, if
any (all as defined below), the Index Maturity, and any other terms relating to
the particular method of calculating the interest rate for such Note and, if so
specified in the applicable Pricing Supplement, that any such Spread and/or
Spread Multiplier may be changed by the Company prior to the Stated Maturity
and, if so, the basis or formula for such change, if any; (x) whether such Note
is an Original Issue Discount Note and, if so, the yield to Stated Maturity;
(xi) whether such Note may be redeemed at the option of the Company, or repaid
at the option of the Holder, prior to Stated Maturity and, if so, the provisions
relating to such redemption or repayment; (xii) whether such Note is an
Extendible Note or a Renewable Note (each as defined below); (xiii) whether such
Note is an Indexed Note (as defined below); (xiv) whether such Note will be
issued initially as a Book-Entry Note or a Certificated Note; and (xv) any other
term of such Note not inconsistent with the provisions of the applicable
Indenture.
 
     Certificated Notes may be presented for registration of transfer or
exchange at the corporate trust office in the Borough of Manhattan, the City of
New York (the "Corporate Trust Office"), of the appropriate Trustee. In the
event Book-Entry Notes are issued through the facilities of DTC, transfers or
exchanges of beneficial interests therein may be similarly effected through a
participating member of The Depository Trust Company ("DTC"). See "-- Book-Entry
Notes" in this Prospectus Supplement and "Description of Debt Securities --
Global Debt Securities" in the accompanying Prospectus. No service charge will
be made for any registration of transfer or exchange of Certificated Notes, but
the Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.
 
     With respect to Book-Entry Notes represented by a Global Note (as defined
below), all references herein to "registered holders" or Holders are to DTC or
its nominee, and not to owners of beneficial interests in such Notes, except as
otherwise provided. See "-- Book-Entry Notes" in this Prospectus Supplement.
 
PAYMENT OF PRINCIPAL AND INTEREST
 
     Unless otherwise specified in the applicable Pricing Supplement, payments
of principal of and any premium and interest on all Notes will be made in U.S.
dollars, provided, however, that payments of principal of and any premium and
interest on Notes denominated in other than U.S. dollars will be made in the
Specified Currency at the option of the Holders thereof under the procedures
described below unless the Specified Currency is not available due to the
imposition of exchange controls or other circumstances beyond the control of the
Company, as described below.
 
     Interest, if any, will be payable on each date specified in the Note on
which an installment of interest is due and payable (each, an "Interest Payment
Date") and at Stated Maturity (or on the date of redemption or repayment if a
Note is redeemed or repaid prior to Stated Maturity) (such Stated Maturity or
date of redemption or repayment, as the case may be, being collectively referred
to as the "Maturity Date"). Interest payments, if any, will be in the amount of
interest accrued from and including the next preceding Interest Payment Date in
respect of which interest has been paid or duly provided for (or from and
including the Original Issue Date if no interest has been paid or provided for
with respect to such Note) to but excluding the Interest Payment Date or the
Maturity Date, as the case may be. However, in the case of Floating Rate Notes
on which the interest rate is reset daily or weekly, the interest payments will,
unless otherwise specified in the applicable Pricing Supplement, include
interest accrued only from but excluding the Regular Record Date (as defined
below) through which interest has been paid (or from and including the Original
Issue Date if no interest has been paid with respect to such Note) through and
including the Regular Record Date next preceding the applicable Interest Payment
Date, except that the interest payment on the Maturity Date will include
interest accrued to but excluding such date. Interest payable on the Maturity
Date will be payable to the person in whose name such Note is registered at the
close of business on the immediately preceding Regular Record Date. If the
Original Issue Date of a Note is between the Regular Record Date and the next
                                      S-12
<PAGE>   13
 
succeeding Interest Payment Date, the first payment of interest thereon will be
made on the Interest Payment Date following the next succeeding Regular Record
Date to the Holder on such next Regular Record Date. The "Regular Record Date"
with respect to a Floating Rate Note will be the fifteenth calendar day (whether
or not a Business Day) next preceding the applicable Interest Payment Date.
 
     Payments on Book-Entry Notes will be made to DTC or its nominee in
accordance with the arrangements then in effect between the appropriate Trustee
and DTC. With respect to Certificated Notes, unless otherwise specified in the
applicable Pricing Supplement, payments of interest and, in the case of
Amortizing Notes, principal and any premium on Notes (other than interest and,
in the case of Amortizing Notes, principal and premium, if any, payable on the
Maturity Date) will be made in U.S. dollars by mailing a check to the Holder at
the address of such Holder appearing on the Security Register for the Notes on
the applicable Regular Record Date, or by wire transfer to such account as may
have been appropriately designated in writing no later than the applicable
Regular Record Date by such person and maintained with a bank located in the
United States. Notwithstanding the foregoing, a Holder of $10,000,000 or more in
aggregate principal amount of Certificated Notes having the same Interest
Payment Date shall be entitled to receive such payments in U.S. dollars by wire
transfer of immediately available funds, but only if appropriate payment
instructions have been received in writing at the Corporate Trust Office of the
appropriate Trustee no later than the applicable Regular Record Date. Payment of
the principal of and any premium and interest due with respect to any
Certificated Note on the Maturity Date to be made in U.S. dollars will be made
in immediately available funds upon surrender of such Note at the Corporate
Trust Office of the appropriate Trustee, provided that the Certificated Note is
presented to such Trustee in time for such Trustee to make such payments in such
funds in accordance with its normal procedures.
 
     If the Specified Currency for a Note is other than U.S. dollars, the
Company will (unless otherwise specified in the applicable Pricing Supplement)
appoint an agent (the "Exchange Rate Agent") to determine the exchange rate for
converting all payments in respect of such Note into U.S. dollars in the manner
described in the following paragraph. Notwithstanding the foregoing, the Holder
of a Note denominated in a Specified Currency other than U.S. dollars may (if
the applicable Pricing Supplement and the Note so indicate) elect to receive all
such payments in the Specified Currency by delivery of a written request to the
appropriate Trustee at its Corporate Trust Office not later than 15 calendar
days prior to the applicable payment date. Such election will remain in effect
until revoked by written notice to such Trustee received not later than 15
calendar days prior to the applicable date.
 
     In the case of a Note denominated in a Specified Currency other than U.S.
dollars, unless the Holder has elected otherwise, payment in respect of such a
Note shall be made in U.S. dollars on the basis of the exchange rate as
determined by the Exchange Rate Agent based on the highest bid quotation for
U.S. dollars received by such Exchange Rate Agent at approximately 11:00 A.M.,
New York City time, on the second Business Day preceding the applicable payment
date (or, if no such rate is quoted on such date, the last date on which such
rate was quoted), from three recognized foreign exchange dealers in the City of
New York selected by the Exchange Rate Agent and approved by the Company (one of
which may be the Exchange Rate Agent) for the purchase by the quoting dealer,
for settlement on such payment date, of the aggregate amount of the Specified
Currency payable on such payment date in respect of all Notes denominated in
such Specified Currency and at which the applicable dealer commits to execute a
contract. All currency exchange costs will be borne by the Holders of such Notes
by deductions from such payments. If three such bid quotations are not available
on the second Business Day preceding the applicable payment date, payments will
be made in the Specified Currency, unless such Specified Currency is unavailable
due to the imposition of exchange controls or other circumstances beyond the
Company's control, in which case payment will be made as described below.
 
     Unless otherwise specified in the applicable Pricing Supplement, a Holder
of a Note denominated in a Specified Currency other than U.S. dollars may
subsequent to the issuance thereof request that future payments be converted or
not be converted, as the case may be, to U.S. dollars by transmitting a written
request for such payments to the Corporate Trust Office of the appropriate
Trustee on or prior to the Regular Record Date or at least 15 calendar days
prior to the Maturity Date. Such request shall include appropriate payment
instructions and shall be in writing (mailed or hand delivered) or by cable,
telex or facsimile
                                      S-13
<PAGE>   14
 
transmission. A Holder may elect to receive all future payments of principal and
any premium and interest in either the Specified Currency or in U.S. dollars, as
specified in the written request, and need not file a separate election for each
payment. Such election will remain in effect until revoked by written notice to
the appropriate Trustee, but written notice of any such revocation must be
received by such Trustee on or prior to the Regular Record Date or at least 15
calendar days prior to the Maturity Date. Holders whose Notes are to be held in
the name of broker or nominee should contact such broker or nominee to determine
whether and how an election to receive payments in the Specified Currency may be
made.
 
     In order for a Holder of a Note, either by the terms of the Note or
pursuant to an election of such Holder, to receive payments of principal and any
premium and interest in a Specified Currency other than U.S. dollars by wire
transfer, such Holder must designate an appropriate account with a bank located
in the country of the Specified Currency (or, with respect to Notes denominated
in ECUs, Brussels) or other jurisdiction acceptable to the Company and the
appropriate Trustee. Such designation shall be made by filing the appropriate
information with the Corporate Trust Office of the appropriate Trustee on or
prior to the Regular Record Date or at least 15 calendar days prior to the
Maturity Date. Such Trustee will, subject to applicable laws and regulations and
until it receives notice to the contrary, make such payment and all succeeding
payments to such Holder of Notes by wire transfer to the designated account,
provided that, in the case of payment of principal and any premium and interest
due on the Maturity Date, the Note is presented to the appropriate Trustee in
time for such Trustee to make such payments in such funds in accordance with its
normal procedures. If a payment cannot be made by wire transfer because the
required information has not been received by such Trustee on or before the
requisite date or for any other reason, a notice will be mailed to the Holder at
its registered address requesting a designation pursuant to which such wire
transfer can be made and, upon such Trustee's receipt of such a designation,
such payment will be made within 15 calendar days of such receipt. In connection
with making all such payments, any tax, assessment or governmental charge
imposed upon payments will be borne by the owners of Book-Entry Notes in respect
of which payments are made.
 
     If the principal of and any premium or interest on any Note is payable in
any currency other than U.S. dollars, and such Specified Currency is not
available due to the imposition of exchange controls or other circumstances
beyond the control of the Company, the Company will be entitled, but not
required, to satisfy its obligations to Holders of Notes by making such payment
in U.S. dollars on the basis of the Market Exchange Rate on the last date such
Specified Currency was available (the "Conversion Date"). Any payment made under
such circumstances in U.S. dollars where the required payment is in other than
U.S. dollars will not constitute an Event of Default under either Indenture.
 
     If payment in respect of a Note is required to be made in any currency unit
(e.g., ECU), and such currency unit is unavailable due to the imposition of
exchange controls or other circumstances beyond the Company's control, then the
Company will be entitled, but not required, to make all payments in respect of
such Note in U.S. dollars until such currency unit is again available. The
amount of each payment in U.S. dollars shall be computed on the basis of the
equivalent of the currency unit in U.S. dollars, which shall be determined by
the Company or its agent on the following basis. The component currencies of the
currency unit for this purpose (the "Component Currencies" or, individually, a
"Component Currency") shall be the currency amounts that were components of the
currency unit as of the Conversion Date for such currency unit. The equivalent
of the currency unit in U.S. dollars shall be calculated by aggregating the U.S.
dollar equivalents of the Component Currencies. The U.S. dollar equivalent of
each of the Component Currencies shall be determined by the Company or such
agent on the basis of the Market Exchange Rate for each such Component Currency
that is available as of the third Business Day prior to the date on which the
relevant payment is due and for each such Component Currency that is
unavailable, if any, as of the Conversion Date for such Component Currency.
 
     If the official unit of any Component Currency is altered by way of
combination or subdivision, the number of units of that currency as a Component
Currency shall be divided or multiplied in the same proportion. If two or more
Component Currencies are consolidated into a single currency, the amounts of
those currencies as Component Currencies shall be replaced by an amount in such
single currency equal to the sum of the amounts of the consolidated Component
Currencies expressed in such single currency. If any
                                      S-14
<PAGE>   15
 
Component Currency is divided into two or more currencies, the amount of the
original Component Currency shall be replaced by the amounts of such two or more
currencies, the sum of which shall be equal to the amount of the original
Component Currency.
 
     All determinations referred to above made by the Company or its agent
(including the Exchange Rate Agent) shall be at its sole discretion and shall,
in the absence of manifest error, be conclusive for all purposes and binding on
the Holders of Notes.
 
     Unless otherwise specified in the applicable Pricing Supplement, if the
principal of any Original Issue Discount Note is declared to be due and payable
immediately as described in the accompanying Prospectus under "Description of
Debt Securities -- Events of Default," the amount of principal due and payable
with respect to such Note shall be the Amortized Face Amount of such Note as of
the date of such declaration. The "Amortized Face Amount" of an Original Issue
Discount Note shall be an amount equal to (i) the Issue Price set forth in the
applicable Pricing Supplement plus (ii) that portion of the difference between
the Issue Price and the principal amount of such Original Issue Discount Note
that has accrued at the yield to Stated Maturity set forth in the Pricing
Supplement (computed in accordance with generally accepted United States bond
yield computation principles) by such Maturity Date, but in no event shall the
Amortized Face Amount of an Original Issue Discount Note exceed its principal
amount.
 
FIXED RATE NOTES
 
     Each Fixed Rate Note will bear interest from its date of issue at the
annual rate or rates stated thereon and in the applicable Pricing Supplement.
Payments of interest on any Fixed Rate Note with respect to any Interest Payment
Date will include interest accrued to but excluding such Interest Payment Date.
Fixed Rate Notes may bear one or more annual rates of interest during the
periods or under the circumstances specified therein and in the applicable
Pricing Supplement. Interest on the Fixed Rate Notes will be computed on the
basis of a 360-day year of twelve 30-day months. With respect to Fixed Rate
Notes other than Amortizing Notes, unless otherwise specified in an applicable
Pricing Supplement, the Interest Payment Dates will be February 15 and August 15
of each year, and the Regular Record Dates will be February 1 and August 1 of
each year.
 
     If any Interest Payment Date or the Maturity Date of a Fixed Rate Note
falls on a day that is not a Market Day (and, in the case of any Note
denominated in other than U.S. dollars, a Business Day in the country issuing
the Specified Currency (or, in the case of ECUs, Brussels)), the payment will be
made on the next Market Day as if it were 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 the Maturity Date, as the case may be.
 
FLOATING RATE NOTES
 
General
 
     Each Floating Rate Note will bear interest at a rate determined by
reference to the Base Rate, which may be adjusted by a Spread and/or Spread
Multiplier. The applicable Pricing Supplement will designate one or more of the
following Base Rates as applicable to each Floating Rate Note: (a) the
Commercial Paper Rate (a "Commercial Paper Rate Note"), (b) the Federal Funds
Effective Rate (a "Federal Funds Effective Rate Note"), (c) the CD Rate (a "CD
Rate Note"), (d) LIBOR (a "LIBOR Note"), (e) the Prime Rate (a "Prime Rate
Note"), (f) the Treasury Rate (a "Treasury Rate Note") or (g) such other Base
Rate or interest rate formula as is set forth in such Pricing Supplement and in
such Floating Rate Note.
 
     Each Floating Rate Note will bear interest from its date of issue to the
first Interest Reset Date (as defined below) for such Note at the Initial
Interest Rate set forth on the face thereof and in the applicable Pricing
Supplement. Thereafter, the interest rate on each Floating Rate Note for each
Reset Period (as defined below) will equal the interest rate calculated by
reference to the Base Rate specified on the face thereof and in the applicable
Pricing Supplement plus or minus a fixed percentage per annum (the "Spread"),
 
                                      S-15
<PAGE>   16
 
if any, and/or times a fixed factor (the "Spread Multiplier"), if any. The
Spread and/or Spread Multiplier for a Floating Rate Note may be subject to
adjustment during a Reset Period under circumstances specified therein and in
the applicable Pricing Supplement.
 
     The Company will appoint, and enter into an agreement with, an agent (a
"Calculation Agent") to calculate interest rates on Floating Rate Notes. Unless
otherwise specified in the applicable Pricing Supplement, the Calculation Agent
for each Floating Rate Note will be the appropriate Trustee.
 
     The rate of interest on each Floating Rate Note will be reset daily,
weekly, monthly, quarterly, semiannually or annually (such type of period being
the "Reset Period" for such Note, and the first day of each Reset Period being
an "Interest Reset Date"), as specified on the face thereof and in the
applicable Pricing Supplement. Unless otherwise specified in the applicable
Pricing Supplement, the Interest Reset Dates 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) that reset weekly, Wednesday of each
week; in the case of Treasury Rate Notes that reset weekly, Tuesday of each
week; in the case of Floating Rate Notes that reset monthly, the third Wednesday
of each month; in the case of Floating Rate Notes that reset quarterly, the
third Wednesday of each March, June, September and December; in the case of
Floating Rate Notes that reset semiannually, the third Wednesday of each of two
months of each year specified on the face thereof and in the applicable Pricing
Supplement; and, in the case of Floating Rate Notes that reset annually, the
third Wednesday of the month of each year specified on the face thereof and in
the applicable Pricing Supplement; provided, however, that (i) the interest rate
in effect from the Original Issue Date to the first Interest Reset Date with
respect to a Floating Rate Note will be the Initial Interest Rate shown on the
face thereof and in the applicable Pricing Supplement, and (ii) the interest
rate in effect for the ten days immediately prior to the Maturity Date of a
Floating Rate Note will be that in effect on the tenth calendar day preceding
such Maturity Date. If an Interest Reset Date for a Floating Rate Note would
otherwise be a day that is not a Market Day, the Interest Reset Date for such
Floating Rate Note shall be postponed to the next day that is a Market Day,
except that, in the case of a LIBOR Note, if such Market Day is in the next
succeeding calendar month, such Interest Reset Date shall be the immediately
preceding Market Day.
 
     The interest rate for each Reset Period will be the rate determined by the
Calculation Agent on or prior to the Calculation Date (as defined below)
pertaining to such Reset Period by reference to the Interest Determination Date
pertaining to such Reset Period. The Interest Determination Date pertaining to a
Reset Period for each type of Floating Rate Note are as follows: the Interest
Determination Date pertaining to a Reset Period for (a) a Commercial Paper Rate
Note (the "Commercial Paper Interest Determination Date"), (b) a Federal Funds
Effective Rate Note (the "Federal Funds Interest Determination Date"), (c) a CD
Rate Note (the "CD Interest Determination Date"), or (d) a Prime Rate Note (the
"Prime Rate Interest Determination Date") will be the second Market Day prior to
the Interest Reset Date that commences such Reset Period. The Interest
Determination Date pertaining to a Reset Period for a LIBOR Note (the "LIBOR
Interest Determination Date") will be the second London Market Day prior to the
Interest Reset Date that commences such Reset Period. The Interest Determination
Date pertaining to a Reset Period for a Treasury Rate Note (the "Treasury
Interest Determination Date") will be the day of the week in which the Interest
Reset Date that commences such Reset Period falls on which Treasury bills (as
defined below) 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 a result of a legal holiday,
an auction is so held on the preceding Friday, such Friday will be the Treasury
Interest Determination Date pertaining to the Reset Period commencing in the
next succeeding week, and the Interest Reset Date for such week shall be the
Tuesday of such week (or, if such Tuesday is not a Market Day, the next
succeeding Market Day). If the auction for such week is held on any day of such
week other than Monday, then such day shall be the Interest Determination Date
and the Interest Reset Date for such week shall be the next succeeding Market
Day. The "Calculation Date," where applicable, pertaining to a Reset Period
shall be the earlier of (i) the tenth calendar day after the Interest
Determination Date pertaining to such Reset Period or, if such day is not a
Market Day the next succeeding Market Day or (ii) the Market Day preceding the
applicable Interest Payment Date or Maturity Date, as the case may be.

     Except as provided below or as otherwise specified in a Pricing Supplement,
interest on Floating Rate Notes will be payable, in the case of Floating Rate
Notes that 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 specified on the face thereof and in the applicable Pricing Supplement; in
the case of Floating Rate Notes that reset quarterly, on the third Wednesday of
March, June, September and December of each year; in the case of Floating Rate
Notes that reset semiannually, on the third Wednesday of each of two months of
each year specified on the face thereof and in the applicable Pricing
Supplement; and, in the case of Floating Rate Notes that reset annually, on the
third Wednesday of the month of each year specified on the face thereof and in
the applicable Pricing Supplement (each such day, with respect to a Floating
Rate Note, being an Interest Payment Date).
 
     If any Interest Payment Date for any Floating Rate Note would fall on a day
that is not a Market Day with respect to such Note (and, in the case of any Note
denominated in other than U.S. dollars, a Business Day in the country issuing
the Specified Currency (or, in the case of ECUs, Brussels)), such Interest
Payment Date will be the following day that is a Market Day with respect to such
Note, except that, in the case of a LIBOR Note, if such Market Day is in the
next-succeeding calendar month, such Interest Payment Date will be the
immediately preceding day that is a Market Day with respect to such LIBOR Note.
If the Maturity Date of any Floating Rate Note would fall on a day that is not a
Market Day, the payment of interest and principal (and premium, if any) may be
made on the next succeeding Market Day, and no interest on such payment will
accrue for the period from and after the Maturity Date.
 
     Each payment of interest on a Floating Rate Note will include interest
accrued to but excluding the applicable Interest Payment Date; provided,
however, that if such Note resets daily or weekly, interest payable on any
Interest Payment Date, other than interest payable on any date on which
principal for such Note is payable, will include interest accrued to and
including the next preceding Regular Record Date. 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 Note by an accrued interest factor. This
accrued interest factor is computed by adding the interest factors calculated
for each day from the date of issue, or from the last date to which interest has
been paid, to the date for which accrued interest is being calculated. The
interest factor (expressed as a decimal rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point (e.g., 9.876541%, or .09876541,
being rounded down to 9.87654%, or .0987654, respectively, and 9.876545%, or
 .09876545, being rounded up to 9.87655%, or .0987655, respectively)) for each
such day is computed by dividing the interest rate (expressed as a decimal
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, as described above) applicable to such date by 360, in the case of
Commercial Paper Rate Notes, Federal Funds Effective Rate Notes, CD Rate Notes,
Prime Rate Notes and LIBOR Notes, or by the actual number of days in the year,
in the case of Treasury Rate Notes.
 
     The Calculation Agent will, upon the request of the Holder of any Floating
Rate Note, provide the interest rate then in effect and, if determined, the
interest rate that will become effective as a result of a determination made on
the most recent Interest Determination Date with respect to such Note.
 
     Any Floating Rate Note may also have either or both of the following: (i) a
maximum numerical interest rate limitation, or ceiling, on the rate of interest
that may accrue during any Reset Period and (ii) a minimum numerical interest
rate limitation, or floor, on the rate of interest that may accrue during any
Reset Period. The interest rate on the 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, the maximum rate
of interest per annum on a simple interest basis, subject to certain exceptions,
for any loan in an amount less than $250,000 is 16% and for any loan in an
amount of $250,000 or more but less than $2,500,000 is 25%. This limit may not
apply to Notes in which $2,500,000 or more has been invested.
 
Commercial Paper Rate Notes
 
     Each Commercial Paper Rate Note will bear interest at the interest rate
(calculated with reference to the Commercial Paper Rate and the Spread and/or
Spread Multiplier, if any) specified in such Commercial Paper Rate Note and in
the applicable Pricing Supplement.
 
                                      S-17

     Unless otherwise indicated in the applicable Pricing Supplement,
"Commercial Paper Rate" means, with respect to any Commercial Paper Interest
Determination Date, the Money Market Yield (calculated as described below) on
such date of the rate for commercial paper having the Index Maturity specified
in the applicable Pricing Supplement as such rate is published by the Board of
Governors of the Federal Reserve System in "Statistical Release H.15(519),
Selected Interest Rates," or any successor publication by such Board of
Governors ("H.15(519)") under the heading "Commercial Paper -- Nonfinancial." If
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 shall be the Money Market Yield on such Commercial Paper
Interest Determination Date of the rate of commercial paper having the specified
Index Maturity as published by the Federal Reserve Bank of New York in its daily
statistical release, "Composite 3:30 P.M. Quotations for U.S. Government
Securities" ("Composite Quotations") under the heading "Commercial Paper." If
such rate is not published in Composite Quotations 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 the Commercial Paper
Interest Determination Date shall be calculated by the Calculation Agent and
shall be the Money Market Yield of the arithmetic mean (each as rounded to the
nearest one hundred-thousandth of a percentage point) 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 the City of
New York selected by the Calculation Agent for commercial paper having the
specified Index Maturity placed for an industrial issuer whose bond rating is
"AA," or the equivalent, from a nationally recognized securities rating agency;
provided, however, that if the dealers selected as aforesaid by the Calculation
Agent are not quoting as mentioned in this sentence, the Commercial Paper Rate
with respect to such Commercial Paper Interest Determination Date will be the
Commercial Paper Rate in effect on such Commercial Paper Interest Determination
Date.
 
     "Money Market Yield" shall be a yield (expressed as a percentage, rounded
to the nearest one hundred-thousandth of a percentage point, as described above
under "-- General") calculated in accordance with the following formula:
 
<TABLE>
           <S>                   <C>             <C>
                                     D X 360
                                  ------------- 
           Money Market Yield =   360 - (D X M)  X 100
</TABLE>
 
where "D" refers to the per annum rate for commercial paper, quoted on a bank
discount basis and expressed as a decimal, and "M" refers to the actual number
of days in the interest period for which interest is being calculated.
 
Federal Funds Effective Rate Notes
 
     Each Federal Funds Effective Rate Note will bear interest at the interest
rate (calculated with reference to the Federal Funds Effective Rate and the
Spread and/or Spread Multiplier, if any) specified in such Federal Funds
Effective Rate Note and in the applicable Pricing Supplement.
 
     Unless otherwise indicated in the applicable Pricing Supplement, "Federal
Funds Effective Rate" means, with respect to any Federal Funds Interest
Determination Date, the rate on such date for federal funds having the Index
Maturity specified in the applicable Pricing Supplement as such rate is
published in H.15(519) under the heading "Federal Funds" (Effective), or, if
such rate is not so published by 9:00 A.M., New York City time, on the
Calculation Date pertaining to such Federal Funds Interest Determination Date,
the Federal Funds Effective Rate will be the rate on such Federal Funds Interest
Determination Date as published in Composite Quotations under the heading
"Federal Funds/Effective Rate." If such rate is not published in Composite
Quotations by 3:00 P.M., New York City time, on the Calculation Date pertaining
to such Federal Funds Interest Determination Date, then the Federal Funds
Effective Rate for such Federal Funds Interest Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean (rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, as
described above under "-- General") of the rates as of 11:00 A.M., New York City
time, on such Federal 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
 
                                      S-18
<PAGE>   19
 
if the brokers selected as aforesaid by the Calculation Agent are not quoting as
mentioned in this sentence, the Federal Funds Effective Rate with respect to
such Federal Funds Interest Determination Date will be the Federal Funds
Effective Rate in effect on such Federal Funds Interest Determination Date.
 
CD Rate Notes
 
     Each CD Rate Note will bear interest at the interest rate (calculated with
reference to the CD Rate and the Spread and/or Spread Multiplier, if any)
specified in such CD Rate Note and in the applicable Pricing Supplement.
 
     Unless otherwise indicated in the applicable Pricing Supplement, "CD Rate"
means, with respect to any CD Interest Determination Date, the rate on such date
for negotiable certificates of deposit having the Index Maturity designated in
the applicable Pricing Supplement as published 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 having the Index Maturity designated in the
applicable Pricing Supplement as published in Composite Quotations under the
heading "Certificates of Deposit." If such rate is not published in Composite
Quotations 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 (each as rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, as
described above under "-- General") of the secondary market offered rates as of
the opening of business, New York City time, on such CD Interest Determination
Date, of three leading non-bank dealers in negotiable U.S. dollar certificates
of deposit in the City of New York selected by the Calculation Agent for
negotiable certificates of deposit of major United States money center banks of
the highest credit standing (in the market for negotiable certificates of
deposit) with a remaining maturity closest to the Index Maturity designated in
the applicable Pricing Supplement in a denomination of $5,000,000; 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.
 
LIBOR Notes
 
     Each LIBOR Note will bear interest at the interest rate (calculated with
reference to LIBOR and the Spread and/or Spread Multiplier, if any) specified in
such LIBOR Note and in the applicable Pricing Supplement.
 
     Unless otherwise specified in the applicable Pricing 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 Pricing Supplement, either: (a) the
     arithmetic mean of the offered rates for deposits in U.S. dollars of not
     less than $1,000,000 having the Index Maturity designated in the applicable
     Pricing Supplement, commencing on the second London Market 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 of not less than $1,000,000 having the Index
     Maturity designated in the applicable Pricing Supplement, commencing on the
     second London Market Day immediately following such LIBOR Interest
     Determination Date, that appears on the 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 the LIBO page 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 page "3750" 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
 
                                      S-19
<PAGE>   20
 
     rates for U.S. dollar deposits). If neither LIBOR Reuters nor LIBOR
     Telerate is specified in the applicable Pricing Supplement, LIBOR will be
     determined as if LIBOR Reuters had been specified. If two or more offered
     rates appear on the Reuters Screen LIBO Page, the rate in respect of such
     LIBOR Interest Determination Date will be the arithmetic mean (rounded, if
     necessary, to the nearest one hundred-thousandth of a percentage point, as
     described above under "-- General") of such offered rates as determined by
     the Calculation Agent. If fewer than two offered rates appear on the
     Reuters Screen LIBO Page, or if no rate appears on the Telerate Page 3750,
     as applicable, LIBOR in respect of that 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 Pricing 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, after consultation with the Company, by the Calculation Agent
     (the "Reference Banks") to prime banks in the London interbank market
     commencing on the second London Market 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. 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
     (rounded, if necessary, to the nearest one hundred-thousandth of a
     percentage point, as described above under "-- General") of such
     quotations. If fewer than two quotations are provided, LIBOR in respect of
     such LIBOR Interest Determination Date will be the arithmetic mean
     (rounded, if necessary, to the nearest one hundred-thousandth of a
     percentage point, as described above under "-- General") 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, after consultation with the Company, 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 the second
     London Market 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 in the City of New York
     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 LIBOR in effect on such LIBOR Interest Determination Date.
 
Prime Rate Notes
 
     Each Prime Rate Note will bear interest at the interest rate (calculated
with reference to the Prime Rate and the Spread and/or Spread Multiplier, if
any) specified in such Prime Rate Note and in the applicable Pricing Supplement.
 
     Unless otherwise indicated in the applicable Pricing Supplement, "Prime
Rate" means, with respect to any Prime Rate Interest Determination Date, the
rate published in H.15(519) for such date under the heading "Bank Prime Loan."
If such rate is not published by 9:00 A.M., New York City time, on the
Calculation Date pertaining to such Prime Rate Interest Determination Date, then
the Prime Rate will be the arithmetic mean, determined by the Calculation Agent,
of the rates of interest publicly announced by each bank that appears on the
Reuters Screen USPRIME 1 Page as such bank's prime rate or base lending rate as
in effect for such Prime Rate Interest Determination Date. If fewer than four
such rates appear on the Reuters Screen USPRIME 1 Page for such Prime Rate
Interest Determination Date, the Prime Rate will be the arithmetic mean,
determined by the Calculation Agent, of the prime rates or base lending 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 Rate Interest Determination Date by three
major banks in the City of New York selected by the Calculation Agent after
 
                                      S-20
<PAGE>   21
 
consultation with the Company; provided, however, that if fewer than three banks
selected as aforesaid by the Calculation Agent are quoting as mentioned in this
sentence, the Prime Rate with respect to such Prime Rate Interest Determination
Date will be the Prime Rate in effect on such Prime Rate Interest Determination
Date. "Reuters Screen USPRIME 1 Page" means the display designated as page
"USPRIME 1" on the Reuters Monitor Money Rates Service (or such other page as
may replace the USPRIME 1 page on that service for the purpose of displaying
prime rates or base lending rates of major United States banks).
 
Treasury Rate Notes
 
     Each Treasury Rate Note will bear interest at the interest rate (calculated
with reference to the Treasury Rate and the Spread and/or Spread Multiplier, if
any) specified in such Treasury Rate Note and in the applicable Pricing
Supplement.
 
     Unless otherwise indicated in the applicable Pricing Supplement, "Treasury
Rate" means, with respect to any Treasury Interest Determination Date, the rate
for the most recent auction of direct obligations of the United States
("Treasury bills") having the Index Maturity specified in the applicable Pricing
Supplement as such rate is published in H.15(519) under the heading "U.S.
Government Securities -- Treasury bills -- auction average (investment)" or, if
such rate is not so published by 9:00 A.M., New York City time, on the
Calculation Date pertaining to such Treasury Interest Determination Date, then
the Treasury Rate shall be the auction average rate (expressed as a bond
equivalent, rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, as described above under "-- General," on the basis of a year
of 365 or 366 days, as applicable, and applied on a daily basis) as otherwise
announced by the United States Department of the Treasury. In the event that the
results of the auction of Treasury bills having the specified Index Maturity are
not published or otherwise 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 (or on the preceding Friday, if applicable), then the Treasury
Rate shall be calculated by the Calculation Agent and shall be a yield to
maturity (expressed as a bond equivalent, rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point, as described above under
"-- General," on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) of the arithmetic mean of the secondary market bid
rates, as of approximately 3:30 P.M., New York City time, on such Treasury
Interest Determination Date, of three leading primary United States government
securities dealers selected, after consultation with the Company, by the
Calculation Agent for the issue of Treasury bills with a remaining maturity
closest to the specified Index Maturity; provided, however, that if the dealers
selected as aforesaid by the Calculation Agent are not quoting as mentioned
above, the Treasury Rate with respect to such Treasury Interest Determination
Date will be the Treasury Rate in effect on such Treasury Interest Determination
Date.
 
INDEXED NOTES
 
     Indexed Notes may be issued with the principal amount payable at maturity
and/or interest to be paid thereon to be determined with reference to the
exchange rate of a specified currency relative to an index (the "Currency
Index"), each as set forth in an applicable Pricing Supplement ("Currency
Indexed Notes"). Holders of such Indexed Notes may receive a principal amount at
maturity that is greater than or less than the face amount of the Indexed Notes
depending upon the relative value at maturity of the Specified Currency compared
to the Currency Index. Information as to the method for determining the
principal amount payable at maturity (or upon redemption or repayment, if
applicable), the relative value of the Specified Currency compared to the
applicable Currency Index and certain additional risks and tax considerations
associated with an investment in Indexed Notes will be set forth in the
applicable Pricing Supplement. See "Foreign Currency Risks" in this Prospectus
Supplement.
 
     The Notes also may be issued as "Indexed Notes", other than Currency
Indexed Notes, that have the principal amount payable at maturity and/or the
interest thereon of which may be determined by reference to one or more equity
or other indices and/or formulae or the price of one or more specified
commodities or by such other methods or formulae as may be specified by the
Company in the applicable Pricing Supplement. The Pricing Supplement relating to
such an Indexed Note will describe, as applicable, the method by which the
amount of interest payable and the amount of principal payable on the Maturity
Date in respect of such an
                                      S-21
<PAGE>   22
 
Indexed Note will be determined, certain special tax consequences to Holders of
such Indexed Note, certain risks associated with an investment in such Indexed
Note and other information relating to such Indexed Note.
 
     AN INVESTMENT IN NOTES INDEXED, AS TO PRINCIPAL OR INTEREST OR BOTH, TO ONE
OR MORE VALUES OF CURRENCIES (INCLUDING EXCHANGE RATES BETWEEN CURRENCIES),
COMMODITIES OR INTEREST RATE INDICES ENTAILS SIGNIFICANT RISKS THAT ARE NOT
ASSOCIATED WITH SIMILAR INVESTMENTS IN A CONVENTIONAL FIXED-RATE DEBT SECURITY.
IF THE INTEREST RATE OF SUCH A NOTE IS SO INDEXED, IT MAY RESULT IN AN INTEREST
RATE THAT IS LESS THAN THAT PAYABLE ON A CONVENTIONAL FIXED-RATE DEBT SECURITY
ISSUED AT THE SAME TIME, INCLUDING THE POSSIBILITY THAT NO INTEREST WILL BE
PAID, AND, IF THE PRINCIPAL AMOUNT OF SUCH A NOTE IS SO INDEXED, THE PRINCIPAL
AMOUNT PAYABLE AT STATED MATURITY MAY BE LESS THAN THE ORIGINAL PURCHASE PRICE
OF SUCH NOTE IF ALLOWED PURSUANT TO THE TERMS OF SUCH NOTE, INCLUDING THE
POSSIBILITY THAT NO PRINCIPAL WILL BE PAID. THE SECONDARY MARKET FOR SUCH NOTES
WILL BE AFFECTED BY A NUMBER OF FACTORS, INDEPENDENT OF THE CREDITWORTHINESS OF
THE COMPANY AND THE VALUE OF THE APPLICABLE CURRENCY, INCLUDING THE VOLATILITY
OF THE APPLICABLE CURRENCY, COMMODITY OR INTEREST RATE INDEX, THE TIME REMAINING
TO THE STATED MATURITY OF SUCH NOTES, THE AMOUNT OUTSTANDING OF SUCH NOTES AND
MARKET INTEREST RATES. THE VALUE OF THE APPLICABLE CURRENCY, COMMODITY OR
INTEREST RATE INDEX DEPENDS ON A NUMBER OF INTERRELATED FACTORS, INCLUDING
ECONOMIC, FINANCIAL AND POLITICAL EVENTS, OVER WHICH THE COMPANY HAS NO CONTROL.
ADDITIONALLY, IF THE FORMULA USED TO DETERMINE THE PRINCIPAL AMOUNT OR INTEREST
PAYABLE WITH RESPECT TO SUCH NOTES CONTAINS A MULTIPLE OR LEVERAGE FACTOR, THE
EFFECT OF ANY CHANGE IN THE APPLICABLE CURRENCY, COMMODITY OR INTEREST RATE
INDEX MAY BE INCREASED. THE HISTORICAL EXPERIENCE OF THE RELEVANT CURRENCIES,
COMMODITIES OR INTEREST RATE INDICES SHOULD NOT BE TAKEN AS AN INDICATION OF
FUTURE PERFORMANCE OF SUCH CURRENCIES, COMMODITIES OR INTEREST RATE INDICES
DURING THE TERM OF ANY NOTE. THE CREDIT RATINGS ASSIGNED TO THE COMPANY'S
MEDIUM-TERM NOTE PROGRAM ARE A REFLECTION OF THE COMPANY'S CREDIT STATUS AND IN
NO WAY ARE A REFLECTION OF THE POTENTIAL IMPACT OF THE FACTORS DISCUSSED ABOVE,
OR ANY OTHER FACTORS, ON THE MARKET VALUE OF THE NOTES. ACCORDINGLY, PROSPECTIVE
INVESTORS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL ADVISORS AS TO THE RISKS
ENTAILED BY AN INVESTMENT IN SUCH NOTES AND THE SUITABILITY OF SUCH NOTES IN
LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.
 
AMORTIZING NOTES
 
     The Company may from time to time offer Amortizing Notes. Unless otherwise
specified in the applicable Pricing Supplement, interest on each Amortizing Note
will be computed on the basis of a 360-day year of twelve 30-day months.
Payments of principal and interest on "Amortizing Notes," which are securities
for which payments of principal and interest are made in equal installments over
the life of the security, will be made either quarterly on each February 15, May
15, August 15 and November 15 or semiannually on each February 15 and August 15,
and on the Maturity Date, unless otherwise specified in an applicable Pricing
Supplement. 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
Pricing Supplement. A table setting forth repayment information in respect of
each Amortizing Note will be included in the applicable Pricing Supplement and
set forth in such Notes.
 
ORIGINAL ISSUE DISCOUNT NOTES
 
     The Company may from time to time offer Original Issue Discount Notes. In
such case, the applicable Pricing Supplement will provide that Holders of such
Notes will not receive periodic payments of interest.
 
     Notwithstanding anything in this Prospectus Supplement to the contrary,
unless otherwise specified in the applicable Pricing Supplement, if a Note is an
Original Issue Discount Note, the amount payable on such Note on a Maturity Date
prior to its Stated Maturity shall be the Amortized Face Amount of such Note as
of such Maturity Date.

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 Pricing 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 appropriate Trustee of such exercise at least 45 but not more than 60
calendar days prior to an Optional Reset Date for such Note. Not later than 40
calendar days prior to such Optional Reset Date, the appropriate Trustee 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, and/or the Spread 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 calendar 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 appropriate Trustee 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 shall be irrevocable. All Notes with respect to which the interest rate
or Spread and/or Spread Multiplier is reset on an Optional Reset 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 appropriate Trustee shall be at
least 25 but not more than 35 calendar 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 appropriate Trustee, revoke any such
tender for repayment until the close of business on the tenth calendar 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 whole year periods (each, an "Extension Period") up to but not
beyond the date (the "Final Maturity Date") set forth in the Pricing Supplement
applicable to such Note (an "Extendible Note"), such Pricing Supplement will
indicate such option and the basis or formula, if any, for setting the interest
rate or the Spread and/or Spread Multiplier, as the case may be, applicable to
any such Extension Period.
 
     The Company may exercise such option with respect to an Extendible Note by
notifying the appropriate Trustee of such exercise at least 30 but not more than
60 calendar days prior to the Stated Maturity of such Extendible Note in effect
prior to the exercise of such option (the "Original Stated Maturity"). No later
than 20 calendar days prior to the Original Stated Maturity, the appropriate
Trustee will mail to the Holder of such
 
                                      S-23
<PAGE>   24
 
Extendible 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 Extendible 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 appropriate Trustee of an Extension Notice to the Holder of an
Extendible Note, the Stated Maturity of such Extendible Note shall 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 Extendible
Note will have the same terms as prior to the mailing of such Extension Notice.
 
     Notwithstanding the foregoing, not later than 20 calendar days prior to the
Original Stated Maturity for an Extendible 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
appropriate Trustee 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 Extendible Note. Such notice shall be irrevocable. All
Extendible 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 an Extendible Note,
the Holder of such Extendible Note will have the option to elect repayment of
such Extendible 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 an Extendible 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 Extendible Note or notification to the appropriate Trustee
shall be at least 25 but not more than 35 calendar days prior to the Original
Stated Maturity, and except that a Holder who has tendered an Extendible Note
for repayment pursuant to an Extension Notice may, by written notice to the
appropriate Trustee, revoke any such tender for repayment until the close of
business on the tenth calendar 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 Pricing Supplement applicable to such
Notes occurring in or prior to the twelfth month following the Original Issue
Date of such Notes (the "Initial Maturity Date"), unless the maturity of all or
any portion of any such Note (a "Renewable Note") is extended 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 Pricing Supplement) prior to the Initial Maturity Date of a Renewable
Note (the "Initial Maturity Extension Date") and on the Interest Payment Date
occurring in each sixth month (or the last month of each Special Election
Interval) after such Initial Maturity Extension Date (each, together with the
Initial Maturity Extension Date, a "Maturity Extension Date"), the maturity of
such Renewable Note, if so specified in the applicable Pricing Supplement, may
be extended to the Interest Payment Date occurring in the twelfth month (or, if
a Special Election Interval is specified in the applicable Pricing Supplement,
the last month in a period equal to twice the Special Election Interval) after
such Maturity Extension Date, if the Holder of such Renewable Note elects to
extend the maturity of such Renewable Note or such portion thereof. If a Holder
does not elect to extend the maturity of any portion of the principal amount of
a Renewable Note during the specified period prior to any Maturity Extension
Date, such portion will become due and payable on the Interest Payment Date
occurring in the sixth month (or the
 
                                      S-24
<PAGE>   25
 
last month in the Special Election Interval) after such Maturity Extension Date
(the "Extended Maturity Date").
 
     A Holder of a Renewable Note may elect to extend the maturity of such
Renewable Note or, if so specified in the applicable Pricing Supplement, any
portion thereof by delivering a notice to such effect to the appropriate Trustee
at its Corporate Trust Office not less than 15 nor more than 30 calendar days
prior to such Maturity Extension Date (unless another period is specified in the
applicable Pricing 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 extend the maturity 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 Pricing Supplement and
only in such principal amount, or any integral multiple in excess thereof, as is
specified in the applicable Pricing Supplement. Notwithstanding the foregoing,
the maturity of the Renewable Notes may not be extended beyond the Stated
Maturity specified for such Renewable Notes in the applicable Pricing
Supplement.
 
     If the Holder elects not to extend the maturity of a Renewable Note, such
Renewable Note must be presented to the appropriate Trustee 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 following 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 appropriate Trustee
shall 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 terminate the automatic extension of maturity was
exercised, with terms identical to those specified in such Renewable Note
(except that such Note shall have a fixed, non-extendible Stated Maturity) and
(ii) if such election is made with respect to less than the full principal
amount of such Holder's Renewable Note, a Note, in a principal amount equal to
the principal amount of such exchanged Renewable Note with respect to which such
election was made, with terms identical to those specified in such exchanged
Renewable Note (except that such Note shall have a fixed, non-extendible Stated
Maturity) and a replacement Renewable Note, in a principal amount equal to the
principal amount of such exchanged Renewable Note with respect to which such
election was not made, with terms identical to those specified in such exchanged
Renewable Note.
 
REDEMPTION AND REPAYMENT
 
     Unless one or more Redemption Dates are specified in the applicable Pricing
Supplement, the Notes will not be redeemable prior to their Stated Maturity. If
one or more Redemption Dates are so specified with respect to any Note, the
applicable Pricing Supplement will also specify one or more redemption prices
(expressed as a percentage of the principal amount of such Note) (each, a
"Redemption Price" and, collectively, the "Redemption Prices") and the
redemption period or periods (each, a "Redemption Period" and, collectively, the
"Redemption Periods") during which such Redemption Prices shall apply. Unless
otherwise specified in the applicable Pricing Supplement, any such Note shall 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 Pricing 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 calendar days' notice. The procedures for
redemption will be described in the applicable Pricing Supplement.
 
     The Pricing Supplement relating to each Note will indicate either that such
Note cannot be repaid prior to its Stated Maturity or that such Note will be
repayable at the option of the Holder on a date or dates specified prior to its
Stated Maturity at a price or prices set forth in the applicable Pricing
Supplement, together with accrued interest to the date of repayment. 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
                                      S-25
<PAGE>   26
 
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 Company, whose
determination will be final, binding and non-appealable.
 
     If a Note is evidenced by a Global Note, DTC or its 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 DTC or its 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 DTC 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 DTC. See "-- Book-Entry Notes" in this Prospectus
Supplement.
 
COMBINATIONS OF PROVISIONS
 
     If so specified in the applicable Pricing 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," "Renewable
Notes" and "Redemption and Repayment."
 
REPURCHASE
 
     The Company may at any time purchase Notes at any price or prices in the
open market or otherwise. Notes so purchased by the Company may be held or
resold or, at the discretion of the Company, may be surrendered to the
appropriate Trustee for cancellation.
 
OTHER PROVISIONS
 
     Any provisions with respect to the determination of an interest rate basis,
the specification of an interest rate basis, calculation of the interest rate
applicable to, or the principal payable at maturity on, any Note, its Interest
Payment Dates or any other matter relating thereto may be modified as specified
under "Other Provisions" on the face of such Note, or in an addendum relating
thereto if so specified on the face thereof, and in the applicable Pricing
Supplement.
 
BOOK-ENTRY NOTES
 
     If indicated in the applicable Pricing Supplement, the Notes may be issued
in whole or in part as Book-Entry Notes evidenced by one or more fully
registered securities (together, the "Global Note"), registered in the name of a
nominee of DTC (the "DTC Nominee"). A Global Note will be held by the
appropriate Trustee, as custodian for DTC and, except as set forth below, a
Global Note may be transferred, in whole and not in part, only to DTC, another
nominee of DTC or a successor of DTC or its nominee.
 
     The provisions set forth under "Description of Debt Securities -- Global
Debt Securities" in the accompanying Prospectus will be applicable to the Notes.
Accordingly, ownership of beneficial interests in the Global Note will be
limited to institutions that have accounts with DTC or the DTC Nominee
("participants") or persons that may hold interests through participants. In
addition, beneficial interests in Book-Entry Notes will be shown on, and
transfers thereof will be effected only through, records maintained by DTC and
its participants. Accordingly, each person owning a beneficial interest in the
Global Note must rely on the procedures of DTC and, if such person is not a
participant, on the procedures of the participant through which such person owns
its interest, to exercise any rights of a Holder under the appropriate
Indenture. The Company understands that, under existing industry practices, in
the event that the Company requests any action of Holders, or an owner of a
beneficial interest in the Global Note desires to give or take any action that a
Holder is entitled to give or take under the appropriate Indenture, DTC would
authorize the participants holding the relevant beneficial interests to give or
take such action, and such participants would authorize
 
                                      S-26
<PAGE>   27
 
beneficial owners owning through such participants to give or take such action
or would otherwise act upon the instructions of beneficial owners owning through
them.
 
     Owners of beneficial interests in the Global Note will not be entitled to
receive Certificated Notes and will not be considered Holders of Notes unless
(i) DTC notifies the Company in writing that it is no longer willing or able to
act as a depositary or if DTC ceases to be a clearing agency registered under
the Securities Exchange Act of 1934 (the "Exchange Act"), (ii) the Company, at
its option, notifies the appropriate Trustee in writing that it elects to cause
the issuance of Certificated Notes or (iii) an Event of Default shall have
occurred and be continuing or any event shall have happened and be continuing
which, after notice or lapse of time, or both, would constitute an Event of
Default with respect to the Notes. In such circumstances, upon surrender by DTC
or a successor depositary of the Global Note, Certificated Notes will be issued
to each person that DTC or a successor depositary identifies as the beneficial
owner of the related Notes. Upon such issuance, the appropriate Trustee is
required to register such Certificated Notes in the name of, and cause the same
to be delivered to, such person or persons (or the nominee thereof). Such
Certificated Notes would be issued in fully registered form without coupons, in
denominations of $100,000 and integral multiples of $1,000 thereof, and
registered in the name or names of such person or persons as DTC shall instruct
the appropriate Trustee. It is expected that such instructions may be based upon
directions received by DTC from its participants with respect to ownership of
beneficial interests in the Global Note.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
laws may impair the ability to transfer beneficial interests in the Global Note.
 
     The Company has been advised by DTC that, upon the issuance of the Global
Note and the deposit of such Global Note with DTC, DTC will immediately credit,
on its book-entry registration and transfer system, the respective principal
amounts represented by such Global Note to the accounts of participants.
 
     DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered under the
Exchange Act. DTC was created to hold securities of its participants and to
facilitate the clearance and settlement of securities transactions among its
participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates. DTC's participants include securities brokers and
dealers (including the Agents), banks, trust companies, clearing corporations
and certain other organizations, some of whom (and/or their representatives) own
DTC. Access to DTC's book-entry system is also available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly. DTC
agrees with and represents to its participants that it will administer its
book-entry system in accordance with its rules and by-laws and requirements of
law.
 
     Principal and interest payments on the Notes registered in the name of
DTC's nominee will be made to the DTC Nominee as the registered owner of the
Global Note. Under the terms of the Indentures, the Company and each Trustee
will treat the person in whose name the Notes are registered as the owners of
such Notes for the purpose of receiving payment of principal and any premium and
interest on such Notes and for all other purposes whatsoever. Therefore, neither
the Company nor either Trustee or any paying agent has any direct responsibility
or liability for the payment of principal or any premium or interest on the
Notes to owners of beneficial interests in the Global Note or for maintaining,
supervising or reviewing any of DTC's records or any participant's records
relating to such beneficial interests. DTC has advised the Company and each
Trustee that its current practice is to credit the accounts of the participants
with payments of principal or any premium or interest on the date payable in
amounts proportionate to their respective holdings in principal amount of
beneficial interests in the Global Note as shown in the records of DTC, unless
DTC has reason to believe that it will not receive payment on such date.
Payments by participants and indirect participants to owners of beneficial
interests in the Global Note will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of the participants or indirect participants.

                         CERTAIN UNITED STATES FEDERAL
                            INCOME TAX CONSEQUENCES
 
     The following summary describes the material United States federal income
tax consequences of the ownership of Notes as of the date hereof. Except where
noted, it deals only with Notes held as capital assets by United States Holders
and does not deal with special situations, such as those of dealers in
securities or currencies, financial institutions, tax-exempt entities, life
insurance companies, persons holding Notes as a part of a hedging, conversion or
constructive sale transaction or a straddle or United States Holders whose
"functional currency" is not the U.S. dollar. Furthermore, the discussion below
is based upon the provisions of the Internal Revenue Code of 1986, as amended
(the "Code"), and regulations, rulings and judicial decisions thereunder as of
the date hereof, and such authorities may be repealed, revoked or modified so as
to result in federal income tax consequences different from those discussed
below. Any special United States federal income tax considerations relevant to a
particular issue of the Notes will be provided in the applicable Pricing
Supplement. PERSONS CONSIDERING THE PURCHASE, OWNERSHIP OR DISPOSITION OF NOTES
SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL INCOME TAX
CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES
ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION.
 
PAYMENTS OF INTEREST
 
     Except as set forth below, interest on a Note will generally be taxable to
a United States Holder as ordinary income at the time it is paid or accrued in
accordance with the United States Holder's method of accounting for tax
purposes. As used herein, a "United States Holder" of a Note means a holder that
is (i) a citizen or resident of the United States, (ii) a corporation or
partnership created or organized in or under the laws of the United States or
any political subdivision thereof, (iii) a trust which is subject to the
supervision of a court within the United States and the control of one or more
United States persons as described in section 7701(a)(30) of the Code, or (iv)
an estate the income of which is subject to United States federal income
taxation regardless of its source. A "Non-United States Holder" is a holder that
is not a United States Holder.
 
ORIGINAL ISSUE DISCOUNT
 
     United States Holders of Notes issued with original issue discount ("OID")
will be subject to special tax accounting rules, as described in greater detail
below. United States Holders of such Notes should be aware that they generally
must include OID in gross income in advance of the receipt of cash attributable
to that income. However, United States Holders of such Notes generally will not
be required to include separately in income cash payments received on the Notes,
even if denominated as interest, to the extent such payments do not constitute
qualified stated interest (as defined below). Notes issued with OID will be
referred to as "Original Issue Discount Notes." Notice will be given in the
applicable Pricing Supplement when the Company determines that a particular Note
will be an Original Issue Discount Note.
 
     This summary is based upon final Treasury regulations addressing debt
instruments issued with OID (the "OID Regulations"). Additional rules applicable
to Original Issue Discount Notes which are denominated in or determined by
reference to a Specified Currency other than the U.S. dollar are described under
"Foreign Currency Notes" below. The following discussion does not address Notes
providing for contingent payments other than Notes that bear qualified stated
interest. Investors should carefully examine the applicable Pricing Supplement
regarding the United States federal income tax consequences of the holding and
disposition of any Notes providing for contingent payments that do not bear
qualified stated interest.
 
     A Note with an "issue price" that is less than its stated redemption price
at maturity (the sum of all payments to be made on the Note other than
"qualified stated interest") will be issued with OID if such difference is at
least 0.25 percent of the stated redemption price at maturity multiplied by the
number of complete years to maturity or, in the case of an Amortizing Note, the
weighted average maturity. The "issue price" of each Note in a particular
offering will be the first price at which a substantial amount of that
particular offering is sold (other than to an underwriter, placement agent or
wholesaler). The term "qualified stated interest" means stated interest that is
unconditionally payable in cash or in property (other than debt
 
                                      S-28
<PAGE>   29
 
instruments of the issuer) at least annually at a single fixed rate or, subject
to certain conditions, based on one or more interest indices. Interest is
payable at a single fixed rate only if the rate appropriately takes into account
the length of the interval between payments. Notice will be given in the
applicable Pricing Supplement when the Company determines that a particular Note
will bear interest that is not qualified stated interest.
 
     In the case of a Note issued with de minimis OID (i.e., discount that is
not OID because it is less than 0.25 percent of the stated redemption price at
maturity multiplied by the number of complete years to maturity), the United
States Holder generally must include such de minimis OID in income as stated
principal payments on the Notes are made in proportion to the stated principal
amount of the Note. Any amount of de minimis OID that has been included in
income shall be treated as capital gain.
 
     Certain of the Notes may be redeemed prior to their Stated Maturity at the
option of the Company and/or at the option of the holder. Original Issue
Discount Notes containing such features may be subject to rules that differ from
the general rules discussed herein. Persons considering the purchase of Original
Issue Discount Notes with such features should carefully examine the applicable
Pricing Supplement and should consult their own tax advisors with respect to
such features since the tax consequences with respect to OID will depend, in
part, on the particular terms and features of the Notes.
 
     United States Holders of Original Issue Discount Notes with a maturity upon
issuance of more than one year must, in general, include OID in income in
advance of the receipt of some or all of the related cash payments. The amount
of OID includible in income by the initial United States Holder of an Original
Issue Discount Note is the sum of the "daily portions" of OID with respect to
the Note for each day during the taxable year or portion of the taxable year in
which such United States Holder held such Note ("accrued OID"). The daily
portion is determined by allocating to each day in any "accrual period" a pro
rata portion of the OID allocable to that accrual period. The "accrual period"
for an Original Issue Discount Note may be of any length and may vary in length
over the term of the Note, provided that each accrual period is no longer than
one year and each scheduled payment of principal or interest occurs on the first
day or the final day of an accrual period. The amount of OID allocable to any
accrual period is an amount equal to the excess, if any, of (a) the product of
the Note's adjusted issue price at the beginning of such accrual period and its
yield to maturity (determined on the basis of compounding at the close of each
accrual period and properly adjusted for the length of the accrual period) over
(b) the sum of any qualified stated interest allocable to the accrual period.
OID allocable to a final accrual period is the difference between the amount
payable at maturity (other than a payment of qualified stated interest) and the
adjusted issue price at the beginning of the final accrual period. Special rules
will apply for calculating OID for an initial short accrual period. The
"adjusted issue price" of a Note at the beginning of any accrual period is equal
to its issue price increased by the accrued OID for each prior accrual period
(determined without regard to the amortization of any acquisition or bond
premium, as described below) and reduced by any payments made on such Note
(other than qualified stated interest) on or before the first day of the accrual
period. Under these rules, a United States Holder will have to include in income
increasingly greater amounts of OID in successive accrual periods. The Company
or its agent is required to provide information returns stating the amount of
OID accrued on Notes held of record by persons other than corporations and other
exempt holders.
 
     In the case of an Original Issue Discount Note that is a Floating Rate
Note, both the "yield to maturity" and "qualified stated interest" will be
determined solely for purposes of calculating the accrual of OID as though the
Note will bear interest in all periods at a fixed rate generally equal to the
rate that would be applicable to interest payments on the Note on its date of
issue or, in the case of certain Floating Rate Notes, the rate that reflects the
yield to maturity that is reasonably expected for the Note. Additional rules may
apply if interest on a Floating Rate Note is based on more than one interest
index. Persons considering the purchase of Floating Rate Notes should carefully
examine the applicable Pricing Supplement and should consult their own tax
advisors regarding the U.S. federal income tax consequences of the holding and
disposition of such Notes.
 
     United States Holders may elect to treat all interest on any Note as OID
and calculate the amount includible in gross income under the constant yield
method described above. For the purposes of this election,
 
                                      S-29
<PAGE>   30
 
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. The election is to be
made for the taxable year in which the United States Holder acquired the Note,
and may not be revoked without the consent of the Internal Revenue Service (the
"IRS"). UNITED STATES HOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS ABOUT
THIS ELECTION.
 
SHORT-TERM NOTES
 
     In the case of Original Issue Discount Notes having a term of one year or
less ("Short-Term Notes"), under the OID Regulations all payments (including all
stated interest) will be included in the stated redemption price at maturity
and, thus, United States Holders will generally be taxable on the discount in
lieu of stated interest. The discount will be equal to the excess of the stated
redemption price at maturity over the issue price of a Short-Term Note, unless
the United States Holder elects to compute this discount using tax basis instead
of issue price. In general, individuals and certain other cash method United
States Holders of a Short-Term Note are not required to include accrued discount
in their income currently unless they elect to do so (but may be required to
include any stated interest in income as it is received). United States Holders
that report income for federal income tax purposes on the accrual method and
certain other United States Holders are required to accrue discount on such
Short-Term Notes (as ordinary income) on a straight-line basis, unless an
election is made to accrue the discount according to a constant yield method
based on daily compounding. In the case of a United States Holder that is not
required, and does not elect, to include discount in income currently, any gain
realized on the sale, exchange or retirement of the Short-Term Note will
generally be ordinary income to the extent of the discount accrued through the
date of sale, exchange or retirement. In addition, a United States Holder that
does not elect to include currently accrued discount in income may be required
to defer deductions for a portion of the United States Holder's interest expense
with respect to any indebtedness incurred or continued to purchase or carry such
Notes.
 
MARKET DISCOUNT
 
     If a United States Holder purchases a Note (other than an Original Issue
Discount Note) for an amount that is less than its stated redemption price at
maturity or, in the case of an Original Issue Discount Note, its adjusted issue
price, the amount of the difference will be treated as "market discount" for
federal income tax purposes, unless such difference is less than a specified de
minimis amount. Under the market discount rules, a United States Holder will be
required to treat any principal payment on, or any gain on the sale, exchange,
retirement or other disposition of, a Note as ordinary income to the extent of
the market discount which has not previously been included in income and is
treated as having accrued on such Note at the time of such payment or
disposition. In addition, the United States Holder may be required to defer,
until the maturity of the Note or its earlier disposition in a taxable
transaction, the deduction of all or a portion of the interest expense on any
indebtedness incurred or continued to purchase or carry such Note.
 
     Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Note, unless the United
States Holder elects to accrue on a constant interest method. A United States
Holder of a Note may elect to include market discount in income currently as it
accrues (on either a ratable or constant interest method), in which case the
rule described above regarding deferral of interest deductions will not apply.
This election to include market discount in income currently, once made, applies
to all market discount obligations acquired on or after the first taxable year
to which the election applies and may not be revoked without the consent of the
IRS.
 
ACQUISITION PREMIUM; AMORTIZABLE BOND PREMIUM
 
     A United States Holder that purchases a Note for an amount that is greater
than its adjusted issue price but equal to or less than the sum of all amounts
payable on the Note after the purchase date other than payments of qualified
stated interest will be considered to have purchased such Note at an
"acquisition premium." Under the acquisition premium rules, the amount of OID
which such United States Holder must include in its gross income with respect to
such Note for any taxable year will be reduced by the portion of such
acquisition premium properly allocable to such year.
                                      S-30
<PAGE>   31
 
     A United States Holder that purchases a Note for an amount in excess of the
sum of all amounts payable on the Note after the purchase date other than
qualified stated interest will be considered to have purchased the Note at a
"bond premium" and will not be required to include any OID in income. A United
States Holder generally may elect to amortize the bond premium over the
remaining term of the Note on a constant yield method as an offset to interest
when includable in income under the United States Holder's regular accounting
method. In the case of instruments that provide for alternative payment
schedules, bond premium is calculated by assuming that (i) the holder will
exercise or not exercise in a manner that maximizes the holder's yield and (ii)
the issuer will exercise or not exercise options in a manner that minimizes the
holder's yield except with respect to call options for which the issuer is
assumed to exercise such call options in a manner that maximizes the holder's
yield. Bond premium on a Note held by a United States Holder that does not make
such an election will decrease the gain or increase the loss otherwise
recognized on disposition of the Note. The election to amortize bond premium on
a constant yield method once made applies to all debt obligations held or
subsequently acquired by the electing United States Holder on or after the first
day of the first taxable year to which the election applies and may not be
revoked without the consent of the IRS.
 
SALE, EXCHANGE AND RETIREMENT OF NOTES
 
     A United States Holder's tax basis in a Note will, in general, be the
United States Holder's cost therefor, increased by OID, market discount or any
discount with respect to a Short-Term Note previously included in income by the
United States Holder and reduced by any amortized premium and any cash payments
on the Note other than qualified stated interest. Upon the sale, exchange or
retirement of a Note, a United States Holder will recognize gain or loss equal
to the difference between the amount realized upon the sale, exchange or
retirement (less any accrued qualified stated interest, which will be taxable as
such) and the adjusted tax basis of the Note. Except with respect to certain
Short-Term Notes as described above, with respect to gain or loss attributable
to changes in exchange rates as described below with respect to certain Foreign
Currency Notes (as defined below) or with respect to market discount as
described above, such gain or loss will be capital gain or loss. Capital gains
of individuals derived in respect of capital assets held for more than one year
are eligible for reduced rates of taxation which may vary depending upon the
holding period of such capital assets. The deductibility of capital losses is
subject to limitations.
 
EXTENDIBLE NOTES, RESET NOTES AND RENEWABLE NOTES
 
     If so specified in an applicable Pricing Supplement relating to a Note, the
Company or a holder may have the option to extend the maturity of a Note. See
"Description of Notes -- Renewable Notes" and "Description of Notes -- Extension
of Maturity." In addition, the Company may have the option to reset the interest
rate, the Spread or the Spread Multiplier. See "Description of Notes -- Interest
Rate Reset." The treatment of a United States Holder of Notes with respect to
which such an option has been exercised is unclear and will depend, in part, on
the terms established for such Notes by the Company pursuant to the exercise of
such option (the "Revised Terms"). Such United States Holder may be treated for
federal income tax purposes as having exchanged such Notes (the "Old Notes") for
new Notes with Revised Terms (the "New Notes"). If the exercise of the option by
the Company is not treated as an exchange of Old Notes for New Notes, no gain or
loss will be recognized by a United States Holder as a result thereof. If the
exercise of the option is treated as a taxable exchange of Old Notes for New
Notes, a United States Holder would recognize gain or loss equal to the
difference between the issue price of the New Notes and the United States
Holder's tax basis in the Old Notes.
 
     The presence of such options may also affect the calculation of OID, among
other things. The OID Regulations provide that, solely for purposes of the
accrual of OID, an issuer of a debt instrument having an option or combination
of options to extend the term of the debt instrument will be presumed to
exercise such option or options in a manner that minimizes the yield on the debt
instrument. Conversely, a holder having a put option, an option to extend the
term of the debt instrument or a combination of such options will be presumed to
exercise such option or options in a manner that maximizes the yield on the debt
instrument. If the exercise of such option or options to extend the term of the
debt instrument actually occurs or the option to put does not occur, contrary to
the presumption made under the OID Regulations (a "change in
 
                                      S-31
<PAGE>   32
 
circumstances"), then, solely for purposes of the accrual of OID, the debt
instrument is treated as reissued on the date of the change in circumstances for
an amount equal to its adjusted issue price on that date. Persons considering
the purchase of Extendible Notes, Reset Notes or Renewable Notes should
carefully examine the applicable Pricing Supplement and should consult their own
tax advisors regarding the U.S. federal income tax consequences of the holding
and disposition of such Notes.
 
FOREIGN CURRENCY NOTES
 
     The following is a summary of the principal United States federal income
tax consequences to a United States Holder of the ownership of a Note
denominated in a Specified Currency other than the U.S. dollar (a "Foreign
Currency Note"). If interest payments are made in a Foreign Currency to a United
States Holder that is not required to accrue such interest prior to its receipt,
such holder will be required to include in income the U.S. dollar value of the
amount received (determined by translating the Foreign Currency received at the
"spot rate" for such Foreign Currency on the date such payment is received),
regardless of whether the payment is in fact converted into U.S. dollars. No
exchange gain or loss is recognized with respect to the receipt of such payment.
 
     A United States Holder that is required to accrue interest on a Foreign
Currency Note prior to receipt of such interest will be required to include in
income for each taxable year the U.S. dollar value of the interest that has
accrued during such year, determined by translating such interest at the average
rate of exchange for the period or periods during which such interest accrued.
The average rate of exchange for an interest accrual period is the simple
average of the exchange rates for each business day of such period (or such
other average that is reasonably derived and consistently applied by the
holder). An accrual basis holder may elect to translate interest income at the
spot rate on the last day of the accrual period (or last day of the taxable year
in the case of an accrual period that straddles the holder's taxable year) or on
the date the interest payment is received if such date is within five days of
the end of the accrual period. Upon receipt of an interest payment on such Note,
such United States Holder will recognize ordinary income or loss in an amount
equal to the difference between the U.S. dollar value of such payment
(determined by translating any Foreign Currency received at the "spot rate" for
such Foreign Currency on the date received) and the U.S. dollar value of the
interest income that such United States Holder has previously included in income
with respect to such payment.
 
     OID on a Note that is also a Foreign Currency Note will be determined for
any accrual period in the applicable Foreign Currency and then translated into
U.S. dollars in the same manner as interest income accrued by a holder on the
accrual basis, as described above. Likewise, a United States Holder will
recognize exchange gain or loss when the OID is paid to the extent of the
difference between the U.S. dollar value of the accrued OID (determined in the
same manner as for accrued interest) and the U.S. dollar value of such payment
(determined by translating any Foreign Currency received at the spot rate for
such Foreign Currency on the date of payment). For this purpose, all receipts on
a Note will be viewed first as the receipt of any stated interest payments
called for under the terms of the Note, second as receipts of previously accrued
OID (to the extent thereof), with payments considered made for the earliest
accrual periods first, and thereafter as the receipt of principal.
 
     The amount of market discount on Foreign Currency Notes includible in
income will generally be determined by translating the market discount
determined in the Foreign Currency into U.S. dollars at the spot rate on the
date the Foreign Currency Note is retired or otherwise disposed of. If the
United States Holder has elected to accrue market discount currently, then the
amount which accrues is determined in the Foreign Currency and then translated
into U.S. dollars on the basis of the average exchange rate in effect during
such accrual period. A United States Holder will recognize exchange gain or loss
with respect to market discount which is accrued currently using the approach
applicable to the accrual of interest income as described above.
 
     Bond premium on a Foreign Currency Note will be computed in the applicable
Foreign Currency. With respect to a United States Holder that elects to amortize
the premium, the amortizable bond premium will reduce interest income in the
applicable Foreign Currency. At the time bond premium is amortized, exchange
 
                                      S-32
<PAGE>   33
 
gain or loss (which is generally ordinary income or loss) will be realized based
on the difference between spot rates at such time and at the time of acquisition
of the Foreign Currency Note. A United States Holder that does not elect to
amortize bond premium will translate the bond premium, computed in the
applicable Foreign Currency, into U.S. dollars at the spot rate on the maturity
date and such bond premium will constitute a capital loss which may be offset or
eliminated by exchange gain.
 
     A United States Holder's tax basis in a Foreign Currency Note will be the
U.S. dollar value of the Foreign Currency amount paid for such Foreign Currency
Note determined at the time of such purchase. A United States Holder that
purchases a Note with previously owned Foreign Currency will recognize exchange
gain or loss at the time of purchase attributable to the difference at the time
of purchase, if any, between his tax basis in such Foreign Currency and the fair
market value of the Note in U.S. dollars on the date of purchase. Such gain or
loss will be ordinary income or loss.
 
     For purposes of determining the amount of any gain or loss recognized by a
United States Holder on the sale, exchange or retirement of a Foreign Currency
Note, the amount realized upon such sale, exchange or retirement will be the
U.S. dollar value of the amount realized in Foreign Currency (other than amounts
attributable to accrued but unpaid interest not previously included in the
holder's income), determined at the time of the sale, exchange or retirement.
 
     A United States Holder will realize exchange gain or loss attributable to
the movement in exchange rates between the time of purchase and the time of
disposition (including the sale, exchange or retirement) of a Foreign Currency
Note. Such gain or loss will be treated as ordinary income or loss. The
recognition of such gain or loss will be limited to the amount of overall gain
or loss realized on the disposition of a Foreign Currency Note. Under the
approach of proposed Treasury Regulations issued on March 17, 1992, if a Foreign
Currency Note is denominated in one of certain hyperinflationary currencies,
generally (i) exchange gain or loss would be realized with respect to movements
in the exchange rate between the beginning and end of each taxable year (or such
shorter period) that such Note was held and (ii) such exchange gain or loss
would be treated as an addition or offset, respectively, to the accrued interest
income on (and an adjustment to the holder's tax basis in) the Foreign Currency
Note.
 
     A United States Holder's tax basis in Foreign Currency received as interest
on (or OID with respect to), or received on the sale or retirement of, a Foreign
Currency Note will be the U.S. dollar value thereof at the spot rate at the time
the holder received such Foreign Currency. Any gain or loss recognized by a
United States Holder on a sale, exchange or other disposition of Foreign
Currency will be ordinary income or loss and will not be treated as interest
income or expense, except to the extent provided in Treasury Regulations or
administrative pronouncements of the IRS.
 
INDEXED NOTES
 
     The tax treatment of a United States Holder of an Indexed Note will depend
on factors including the specific index or indices used to determine indexed
payments on the Note and the amount and timing of any contingent and
noncontingent payments of principal and interest. Persons considering the
purchase of Indexed Notes should carefully examine the applicable Pricing
Supplement and should consult their own tax advisors regarding the U.S. federal
income tax consequences of the holding and disposition of such Notes.
 
NON-UNITED STATES HOLDERS
 
     Under present United States federal income and estate tax law, and subject
to the discussion below concerning backup withholding:
 
          (a) no withholding of United States federal income tax will be
     required with respect to the payment by the Company or any Paying Agent of
     principal or interest (which for purposes of this discussion includes OID)
     on a Note owned by a Non-United States Holder, provided (i) that the
     beneficial owner does not actually or constructively own 10% or more of the
     total combined voting power of all classes of stock of the Company entitled
     to vote within the meaning of section 871(h)(3) of the Code and the
     regulations thereunder, (ii) the beneficial owner is not a controlled
     foreign corporation that is related to
 
                                      S-33
<PAGE>   34
 
     the Company through stock ownership, (iii) the beneficial owner is not a
     bank whose receipt of interest on a Note is described in section
     881(c)(3)(A) of the Code, (iv) the beneficial owner satisfies the statement
     requirement (described generally below) set forth in section 871(h) and
     section 881(c) of the Code and the regulations thereunder and (v) such
     interest is not considered to be contingent interest within the meaning of
     section 871(h)(4)(A) of the Code and the regulations thereunder;
 
          (b) no withholding of United States federal income tax will be
     required with respect to any gain or income realized by a Non-United States
     Holder upon the sale, exchange or retirement of a Note; and
 
          (c) a Note beneficially owned by an individual who at the time of
     death is a Non-United States Holder will not be subject to United States
     federal estate tax as a result of such individual's death, provided that
     such individual does not actually or constructively own 10% or more of the
     total combined voting power of all classes of stock of the company entitled
     to vote within the meaning of section 871(h)(3) of the Code and provided
     that the interest payments with respect to such Note would not have been,
     if received at the time of such individual's death, effectively connected
     with the conduct of a United States trade or business by such individual.
 
     To satisfy the requirement referred to in (a)(iv) above, the beneficial
owner of such Note, or a financial institution holding the Note on behalf of
such owner, must provide, in accordance with specified procedures, a paying
agent of the Company with a statement to the effect that the beneficial owner is
not a U.S. person. Currently, these requirements will be met if (1) the
beneficial owner provides his name and address, and certifies, under penalties
of perjury, that he is not a U.S. person (which certification may be made on an
IRS Form W-8 (or successor form)) or (2) a financial institution holding the
Note on behalf of the beneficial owner certifies, under penalties of perjury,
that such statement has been received by it and furnishes a paying agent with a
copy thereof. Under recently finalized Treasury regulations (the "Final
Regulations"), the statement requirement referred to in (a)(iv) above may also
be satisfied with other documentary evidence for interests paid after December
31, 1999 with respect to an offshore account or through certain foreign
intermediaries.
 
     If a Non-United States Holder cannot satisfy the requirements of the
"portfolio interest" exception described in paragraph (a) above, payments of
premium, if any, and interest (including OID) made to non-United States Holders
will be subject to a 30% withholding tax unless the beneficial owner of the Note
provides the Company or its paying agent, as the case may be, with a properly
executed (1) IRS Form 1001 (or successor form) claiming an exemption from or a
reduction of withholding under the benefit of a tax treaty or (2) IRS Form 4224
(or successor form) stating that interest paid on the Note is not subject to
withholding tax because it is effectively connected with the beneficial owner's
conduct of a trade or business in the United States. Under the Final
Regulations, Non-United States Holders will generally be required to provide IRS
Form W-8 in lieu of IRS Form 1001 and IRS Form 4224, although alternative
documentation may be applicable in certain situations.
 
     If a Non-United States Holder is engaged in a trade or business in the
United States and premium, if any, or interest (including OID) on the Note is
effectively connected with the conduct of such trade or business, the non-United
States Holder, although exempt from the withholding tax discussed above, will be
subject to United States federal income tax on such premium, interest and OID on
a net income basis in the same manner as if it were a United States Holder. In
addition, if such holder is a foreign corporation, it may be subject to a branch
profits tax equal to 30% of its effectively connected earnings and profits for
the taxable year, subject to adjustments. For this purpose, such premium, if
any, and interest (including OID) on a Note will be included in such foreign
corporation's earnings and profits.
 
     Any gain or income realized upon the sale, exchange or retirement of a Note
generally will not be subject to United States federal income tax unless (i)
such gain or income is effectively connected with a trade or business in the
United States of the Non-United States Holder, or (ii) in the case of a
Non-United States Holder who is an individual, such individual is present in the
United States for 183 days or more in the taxable year of such sale, exchange or
retirement, and certain other conditions are met.
 
                                      S-34

INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     In general, information reporting requirements will apply to certain
payments of principal, interest, OID and premium paid on Notes and to the
proceeds of sale of a Note made to United States Holders other than certain
exempt recipients (such as corporations). A 31% backup withholding tax will
apply if the United States Holder fails to provide a taxpayer identification
number or certification of exempt status or fails to report in full dividend and
interest income.
 
     No information reporting or backup withholding will be required with
respect to payments made by the Company or any paying agent to Non-United States
Holders if a statement described in (a)(iv) under "Non-United States Holders"
has been received and the payor does not have actual knowledge that the
beneficial owner is a United States person.
 
     In addition, backup withholding and information reporting will not apply if
payments of the principal, interest, OID or premium on a Note are paid or
collected by a foreign office of a custodian, nominee or other foreign agent on
behalf of the beneficial owner of such Note, or if a foreign office of a broker
(as defined in applicable Treasury regulations) pays the proceeds of the sale of
a Note to the owner thereof. If, however, such nominee, custodian, agent or
broker is, for United States federal income tax purposes, a U.S. person, a
controlled foreign corporation or a foreign person that derives 50% or more of
its gross income for certain periods from the conduct of a trade or business in
the United States or, for taxable years beginning after December 31, 1999, a
foreign partnership, in which one or more United States persons, in the
aggregate, own more than 50% of the income or capital interests in the
partnership or which is engaged in a trade or business in the United States,
such payments will not be subject to backup withholding but will be subject to
information reporting, unless (1) such custodian, nominee, agent or broker has
documentary evidence in its records that the beneficial owner is not a U.S.
person and certain other conditions are met or (2) the beneficial owner
otherwise establishes an exemption.
 
     Payments of principal, interest, OID and premium on a Note paid to the
beneficial owner of a Note by a United States office of a custodian, nominee or
agent, or the payment by the United States office of a broker of the proceeds of
sale of a Note, will be subject to both backup withholding and information
reporting unless the beneficial owner provides the statement referred to in
(a)(iv) above and the payor does not have actual knowledge that the beneficial
owner is a United States person or otherwise establishes an exemption.
 
     Any amounts withheld under the backup withholding rules will be allowed as
a refund or a credit against such holder's U.S. federal income tax liability
provided the required information is furnished to the IRS.
 
                         IMPORTANT CURRENCY INFORMATION
 
     Purchasers are required to pay for each Note in the Specified Currency for
such Note. Currently, there are limited facilities in the United States for
conversion of U.S. dollars into foreign currencies and vice versa, and banks
generally do not offer non-U.S. dollar checking or savings account facilities in
the United States. However, if requested by a prospective purchaser of Notes
denominated in a Specified Currency other than U.S. dollars, the Agent
soliciting the offer to purchase will arrange for the conversion of U.S. dollars
into such Specified Currency other than U.S. dollars to enable the purchaser to
pay for such Notes. Such requests must be made on or before the fifth Business
Day preceding the date of delivery of the Notes or by such other date as
determined by the Agent which presents the offer to the Company. Each such
conversion will be made by the relevant Agent on such terms and subject to such
conditions, limitations and charges as such Agent may from time to time
establish in accordance with its regular foreign exchange practice. All costs of
exchange will be borne by the relevant purchaser of the Notes.

                             FOREIGN CURRENCY RISKS
 
EXCHANGE RATES AND EXCHANGE CONTROLS
 
     Any investment in Notes that are denominated in, or the payment of which is
related to the value of, a Specified Currency other than U.S. dollars entails
significant risks that are not associated with a similar investment in a
security denominated in U.S. dollars. Such risks include, without limitation,
the possibility of significant changes in rates of exchange between the U.S.
dollar and the various foreign currencies (or composite currencies) and the
possibility of the imposition or modification of exchange controls by either the
United States or foreign governments. Such risks generally depend on economic
and political events over which the Company has no control. In recent years,
rates of exchange between U.S. dollars and certain foreign currencies have been
highly volatile and such volatility may be expected to continue in the future.
Fluctuations in any particular exchange rate that have occurred in the past are
not necessarily indicative, however, of fluctuations in such rate that may occur
during the term of any Note. Depreciation against the U.S. dollar of the
currency in which a Note is payable would result in a decrease in the effective
yield of such Note below its stated interest rate and, in certain circumstances,
could result in a loss to the investor on a U.S. dollar basis.
 
     THIS PROSPECTUS SUPPLEMENT, THE ACCOMPANYING PROSPECTUS AND ANY PRICING
SUPPLEMENT DO NOT DESCRIBE ALL THE RISKS OF AN INVESTMENT IN NOTES DENOMINATED
IN A FOREIGN CURRENCY OR A COMPOSITE CURRENCY AND THE COMPANY DISCLAIMS ANY
RESPONSIBILITY TO ADVISE PROSPECTIVE PURCHASERS OF SUCH RISKS AS THEY EXIST AT
THE DATE OF THIS PROSPECTUS SUPPLEMENT OR AS SUCH RISKS MAY CHANGE FROM TIME TO
TIME. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL
ADVISORS AS TO THE RISKS ENTAILED BY AN INVESTMENT IN NOTES DENOMINATED IN
SPECIFIED CURRENCIES OTHER THAN U.S. DOLLARS. SUCH NOTES ARE NOT AN APPROPRIATE
INVESTMENT FOR INVESTORS WHO ARE UNSOPHISTICATED WITH RESPECT TO FOREIGN
CURRENCY TRANSACTIONS.
 
     The information set forth in this Prospectus Supplement is directed to
prospective purchasers who are U.S. residents, and the Company disclaims any
responsibility to advise prospective purchasers who are residents of countries
other than the United States with respect to any matters that may affect the
purchase, holding or receipt of payments of principal or any premium or interest
on the Notes. Such persons should consult their own counsel with regard to such
matters.
 
     Governments have imposed from time to time, and may in the future impose,
exchange controls that could affect exchange rates as well as the availability
of a specified foreign currency at the time of payment of principal or any
premium or interest on a Note. Even if there are no actual exchange controls, it
is possible that the Specified Currency for any particular Note not denominated
in U.S. dollars would not be available when payments on such Note are due. In
that event, the Company would make required payments in U.S. dollars on the
basis of the Market Exchange Rate on the date of such payment, or if such rate
of exchange is not then available, on the basis of the Market Exchange Rate as
of the most recent practicable date.
 
     With respect to any Note denominated in a foreign currency or currency
unit, the applicable Pricing Supplement will include information with respect to
applicable currency exchange controls, if any, and historical exchange rate
information on such currency or currency unit. The information contained therein
shall constitute a part of this Prospectus Supplement and is furnished as a
matter of information only and should not be regarded as indicative of the range
of or trends in fluctuations in currency exchange rates that may occur in the
future.
 
GOVERNING LAW AND JUDGMENTS
 
     The Notes will be governed by and construed in accordance with the laws of
the State of New York. In the event an action based on Notes denominated in a
Specified Currency other than U.S. dollars were commenced in a court in the
United States, it is likely that such court would grant judgment relating to the
Notes only in U.S. dollars. If an action based on Notes denominated in a
Specified Currency other than U.S. dollars were commenced in a New York court,
however, it is likely that such court would render or enter a judgment or decree
in the Specified Currency. Such judgment would then be converted into U.S.
dollars at the rate of exchange prevailing on the date of entry of the judgment
or decree.

                       SUPPLEMENTAL PLAN OF DISTRIBUTION
 
     The Notes are being offered on a continuing basis by the Company through
the agents listed on the cover (the "Agents"), each of which has agreed to use
its reasonable best efforts to solicit purchases of the Notes. The Company will
pay each Agent a commission of from .125% to .750% of the principal amount of
each Note, depending on its Stated Maturity, sold through such Agent, unless the
Company and such Agent shall otherwise agree. Each Agent will have the right, in
its discretion reasonably exercised, to reject in whole or in part, any offer to
purchase Notes received by such Agent. The Company also may sell Notes to any
Agent, acting as principal, at a discount to be agreed upon at the time of sale,
for resale to one or more investors or to another broker-dealer (acting as
principal for purposes of resale) at varying prices related to prevailing market
prices at the time of resale, as determined by such Agent. Unless otherwise
indicated in the applicable Pricing Supplement, if any Note is resold by an
Agent to any dealer at a discount, such discount will not be in excess of the
discount received by such Agent from the Company. In addition, unless otherwise
indicated in the applicable Pricing Supplement, any Note purchased by an Agent
as principal will be purchased at 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 reserves the right to sell Notes directly to
investors on its own behalf in those jurisdictions where it is authorized to do
so. In such circumstances, the Company will have the sole right to accept offers
to purchase Notes and may reject any proposed purchase of Notes in whole or in
part, In the case of sales made directly by the Company, no commission will be
payable. The Company also reserves the right to sell Notes through agents other
than the Agents subject to certain conditions set forth in the Distribution
Agreement. The commission applicable to agency sales through any such other
agents will be the same as that applicable to agency sales through the Agents.
The Company reserves the right to withdraw, cancel or modify the offer made
hereby without notice.
 
     The Agents may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933 (the "Act"). The Company has agreed to indemnify each
Agent against certain liabilities, including liabilities under the Act, or to
contribute to payments each Agent may be required to make in respect thereof.
The Company has agreed to reimburse the Agents for certain of the Agents'
expenses, including, but not limited to, the fees and expenses of counsel to the
Agents.
 
     In addition to offering the Notes through the Agents as described herein,
the Company may sell other Debt Securities. Under certain circumstances, the
sale of such Debt Securities may reduce the maximum aggregate amount of Notes
that may be offered by this Prospectus Supplement.
 
     No Note will have an established trading market when issued. The Company
has been advised by each Agent that it may from time to time purchase and sell
Notes in the secondary market, but it is not obligated to do so. There can be no
assurance that there will be a secondary market for the Notes or liquidity in
the secondary market if one develops. From time to time, each Agent may make a
market in the Notes.
 
     In connection with certain types of offers and sales of Notes, the rules of
the Securities and Exchange Commission permit the Agents to engage in certain
transactions that stabilize the price of the Notes. Such transactions may
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the Notes, the purchase of Notes to cover syndicate short positions
and the imposition of a penalty bid. If such Agents create a short position in
the Notes in connection with the offering (i.e., if they sell more Notes than
are set forth in the applicable Pricing Supplement), the Agents may reduce that
short position by purchasing Notes in the open market. In general, purchases of
a security for the purpose of stabilization or to reduce a syndicate short
position could cause the price of the security to be higher than it might
otherwise be in the absence of such purchases.
 
     Each Agent and certain of its affiliates may from time to time engage in
transactions with, and perform investment banking and other financial services
for, the Company in the ordinary course of business.

                                  THE COMPANY
 
     MBNA Corporation (the "Company"), is a registered bank holding company
incorporated under the laws of Maryland in 1990. It is the parent corporation of
MBNA America Bank, National Association (the "Bank"), a national bank organized
in January 1991, as the successor to a national bank organized in 1982.
 
     The Company's principal executive offices are located in Wilmington,
Delaware 19884, and its telephone number is (800) 362-6255.
 
YEAR 2000
 
     Many computer applications have been written using two digits rather than
four to define the applicable year, and therefore may not recognize a date using
"00" as the Year 2000. This could result in the inability of the application to
properly process transactions with dates in the Year 2000 or thereafter. The
Company has substantially completed an assessment of the impact of this problem
on its computer systems and applications, including the systems that service the
Company's loans, and is executing a plan to make the necessary programming
changes, and has begun to test and implement them. The Company expects to
complete implementation of the necessary changes to its mainframe, distributed,
and desktop systems by the end of 1998, and its other systems by mid-1999.
 
     The Company is actively monitoring the progress of third parties, whose
systems provide information to the Company's system, in achieving Year 2000
compliance and is developing contingency plans to address any failure of a
critical vendor to do so. Based on its efforts and the information available to
date, and assuming the continued availability of staff and other technical
resources, and no unexpected difficulty in implementing system enhancements, the
Company believes that it will not incur significant operational disruptions or
material costs as a result of the Year 2000 problem. However, there can be no
assurance that the systems of third parties with which the Company deals will be
timely converted and will not adversely affect the Company's business.
 
                                USE OF PROCEEDS
 
     Except as otherwise described in the applicable Prospectus Supplement, the
net proceeds from the sale of the Securities offered hereby will be applied to
the Company's general funds to be utilized for general corporate purposes,
including the reduction of short-term debt, possible acquisitions, investments
in, or extension of credit to, the Company's subsidiaries and the possible
acquisition of real property for use in the Company's business.

(a) Preferred Stock dividend requirements are adjusted to represent a pretax
    earnings equivalent.
 
     The ratio of earnings to fixed charges is computed by dividing (i) income
before income taxes and fixed charges less interest capitalized during such
period, net of amortization of previously capitalized interest, by (ii) fixed
charges. The ratio of earnings to combined fixed charges and preferred stock
dividend requirements is computed by dividing (i) income before income taxes and
fixed charges less interest capitalized during such period, net of amortization
of previously capitalized interest, by (ii) fixed charges and preferred stock
dividend requirements. Fixed charges consist of interest expense on borrowings,
including capitalized interest (including or excluding deposits, as applicable),
and the portion of rental expense which is deemed representative of interest.
The preferred stock dividend requirements represent the pretax earnings which
would have been required to cover such dividend requirements on the Company's
preferred stock outstanding. The Company did not have any preferred stock
outstanding during the periods prior to 1995 presented above and accordingly
there were no preferred stock dividend requirements during such periods.
 
                               REGULATORY MATTERS
 
     The following discussion sets forth certain of the elements of the
comprehensive regulatory framework applicable to bank holding companies and
banks and provides certain specific information relevant to the Company and its
subsidiaries. Federal regulation of financial institutions such as the Company
and the Bank is intended primarily for the protection of depositors and the Bank
Insurance Fund rather than shareholders or other creditors.
 
GENERAL
 
     As a bank holding company, the Company is subject to the supervision of the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board").
The Bank is subject to supervision and examination by applicable federal
agencies, principally the Office of the Comptroller of the Currency (the "OCC"),
which is the Bank's primary regulator. The Bank's deposits are insured by, and
therefore the Bank is also subject to the regulations of, the Federal Deposit
Insurance Corporation ("FDIC"). In addition to the impact of regulation,
commercial banks are affected significantly by the actions of the Federal
Reserve Board as it attempts to control the money supply and credit availability
in order to influence the economy.
 
     As a bank holding company, the Company is also subject to regulation under
the Bank Holding Company Act of 1956 (the "BHCA") and to the BHCA's examination
and reporting requirements. Under the BHCA, bank holding companies must, in some
cases, obtain the approval of the Federal Reserve Board prior to acquiring
direct or indirect ownership or control of more than five percent of the voting
shares or substantially
 
                                        6
<PAGE>   46
 
all of the assets of any company, including a bank. In addition, bank holding
companies are prohibited under the BHCA from engaging in nonbanking activities
other than those that the Federal Reserve Board has determined are closely
related to banking.
 
     The earnings of the Bank, and therefore the earnings of the Company, are
affected by general economic conditions, management policies and the legislative
and governmental actions of various regulatory authorities, including the
Federal Reserve Board, the FDIC and the OCC. In addition, there are numerous
governmental requirements and regulations which affect the activities of the
Company.
 
DIVIDEND RESTRICTIONS
 
     The Company is a legal entity separate and distinct from its banking and
other subsidiaries. The principal source of cash flow of the Company, including
cash flow to pay dividends on its stock or principal (premium, if any) and
interest on debt securities, is dividends from the Bank. The approval of the OCC
is required for any dividend paid or declared by a national bank if the total of
all dividends paid or declared by the bank in any calendar year would exceed the
total of its net income for that year combined with its retained net income for
the preceding two years less any required transfers to surplus or a fund for the
retirement of any preferred stock. In addition, a national bank may not pay a
dividend in an amount greater than its undivided profits. Under current
regulatory practice, national banks may pay dividends only out of current
operating earnings. The payment of dividends by the Bank may also be affected by
other factors, such as requirements for the maintenance of adequate capital.
Under these provisions, the Bank could have declared, as of June 30, 1998,
without obtaining prior regulatory approval, aggregate dividends of
approximately $983.2 million. The Bank's payment of dividends to the Company may
also be limited by a tangible net worth requirement under the Bank's revolving
credit facility. This facility was not drawn upon as of June 30, 1998. If this
facility was drawn upon as of June 30, 1998, the amount of retained earnings
available for declaration of dividends would have been limited to $708.7
million.
 
     In addition, under the Federal Deposit Insurance Corporation Improvement
Act of 1991 ("FDICIA"), a FDIC-insured depository institution may not make
capital distributions (including the payment of dividends) or pay any management
fees to its holding company if it is undercapitalized or if such payment would
cause it to become undercapitalized. See "-- FDICIA and FDIC Insurance."
 
HOLDING COMPANY STRUCTURE
 
     The Bank is subject to restrictions under federal law which limit the
transfer of funds by the Bank to the Company and its nonbanking subsidiaries,
whether in the form of loans, extensions of credit, investments or asset
purchases. Such transfers by the Bank to the Company or any nonbanking
subsidiary are limited in amount to 10% of the Bank's capital and surplus and,
with respect to the Company and all such nonbanking subsidiaries, to an
aggregate of 20% of the Bank's capital and surplus. Furthermore, loans and
extensions of credit by the Bank to the Company or its nonbanking subsidiaries
are required to be secured in specified amounts.
 
     Extensions of credit and other transactions between the Bank and the
Corporation must be on terms and under circumstances, including credit
standards, that are substantially the same or at least as favorable to the Bank
as those prevailing at the time for comparable transactions with non-affiliated
companies.
 
     Under Federal Reserve Board policy, the Company is expected to act as a
source of financial strength to each of its subsidiary banks and to commit
resources to support each such subsidiary bank, in circumstances where the
Company might not do so absent such policy. Any capital loans by the Company to
a subsidiary bank would also be subordinate in right of payment to deposits and
to certain other indebtedness of such bank. In addition, the Crime Control Act
of 1990 provides that in the event of a bank holding company's bankruptcy, any
commitment by the bank holding company to a federal bank regulatory agency to
maintain the capital of a subsidiary bank will be assumed by the bankruptcy
trustee and entitled to a priority of payment.
 
                                        7
<PAGE>   47
 
     Federal law permits the OCC to order the pro rata assessment of
shareholders of a national bank whose capital stock has become impaired, by
losses or otherwise, to relieve a deficiency in such national bank's capital
stock. The statute also provides for the enforcement of any such pro rata
assessment of shareholders of such national bank to cover such impairment of
capital stock by sale, to the extent necessary, of the capital stock of any
assessed shareholder failing to pay the assessment. The Company, as the sole
stockholder of the Bank, is subject to such provisions.
 
CAPITAL ADEQUACY
 
     Under the Federal Reserve Board's risk-based capital guidelines for bank
holding companies and member banks, the minimum ratio of total capital to
risk-adjusted assets (including certain off-balance sheet items) is 8%. At least
half of the total capital is to be comprised of common equity, retained
earnings, minority interests in consolidated subsidiaries, noncumulative
perpetual preferred stock and a limited amount of cumulative perpetual preferred
stock, less goodwill and less certain other disallowed intangible assets and
disallowed deferred tax assets ("Tier 1 capital"). The remainder ("Tier 2
capital") may consist of hybrid capital instruments, perpetual debt, mandatory
convertible debt securities, a limited amount of subordinated debt, other
preferred stock and a limited amount of loan and lease loss reserves. The total
of Tier 1 capital and Tier 2 capital is referred to as "Total capital." In
addition, the Federal Reserve Board has approved minimum leverage ratio
guidelines for bank holding companies and state member banks. These guidelines
provide for a minimum ratio of Tier 1 capital to quarterly average assets
("Leverage Ratio") of 3% for bank holding companies and state member banks that
meet certain specified criteria, including that they have the highest regulatory
rating. All other bank holding companies and state member banks will be required
to maintain a Leverage Ratio of 3% plus an additional cushion of 100 to 200
basis points. The guidelines also provide that banking organizations
experiencing internal growth or making acquisitions will be expected to maintain
strong capital positions substantially above the minimum supervisory levels,
without significant reliance on intangible assets. Furthermore, the guidelines
indicate that the Federal Reserve Board will continue to consider a "tangible
Tier 1 leverage ratio" in evaluating proposals for expansion or new activities.
The tangible Tier 1 leverage ratio is the ratio of a banking organization's Tier
1 capital, less all intangibles, to total assets. The Bank is also subject to
similar capital requirements adopted by the OCC. Under the guidelines, as of
June 30, 1998, the Company's Tier 1 and total capital to risk-adjusted assets
ratios were 10.78% and 14.02%, respectively, and the Company's Leverage Ratio
was 11.28%. As of June 30, 1998, the Bank's Tier 1 and total capital to
risk-adjusted assets ratios were 10.99% and 13.90%, respectively, and the Bank's
Leverage Ratio was 11.55%.
 
     On November 20, 1997, the OCC, the Federal Reserve, the FDIC and the Office
of Thrift Supervision proposed for comment regulations establishing new
risk-based capital requirements for recourse arrangements and direct credit
substitutes. "Recourse" for this purpose means any retained risk of loss
associated with any transferred asset that exceeds a pro rata share of the
bank's or holding company's remaining claim on the asset, if any. Under existing
regulations, banks and bank holding companies have to maintain capital against
the full amount of any assets for which risk of loss is retained, unless the
resulting capital amount would exceed the maximum contractual liability or
exposure retained, in which case the capital required would equal,
dollar-for-dollar, such maximum contractual liability or exposure. The proposal
would extend this treatment to direct credit substitutes. "Direct credit
substitute" means any assumed risk of loss associated with any asset or other
claim that exceeds the bank's or holding company's pro rata share of the asset
or claim, if any.
 
     One aspect of the proposal specifically addresses securitizations and would
base the capital charge for such transactions on credit ratings from nationally
recognized statistical rating agencies.
 
FDICIA AND FDIC INSURANCE
 
     FDICIA provides for expanded regulation of banks and bank holding
companies. The expanded regulation includes expanded federal banking agency
examinations and increased powers of federal banking agencies to take corrective
action to resolve the problems of insured depository institutions with capital
deficiencies. Those powers vary depending on which of several levels of
capitalization a particular institution
                                        8
<PAGE>   48
 
meets. FDICIA establishes five capital tiers: well-capitalized, adequately
capitalized, undercapitalized, significantly undercapitalized and critically
undercapitalized.
 
     FDICIA permits only "well capitalized" institutions to accept brokered
deposits without restrictions. As of June 30, 1998 the Bank met the FDIC's
definition of a well capitalized institution for purposes of accepting brokered
deposits. For the purposes of the brokered deposit rules, a bank is defined to
be "well capitalized" if it maintains a ratio of Tier 1 capital to risk-adjusted
assets of at least 6.0%, a ratio of Total capital to risk-adjusted assets of at
least 10.0% and a leverage ratio of at least 5.0% and is not subject to any
order, direction or written agreement to maintain specific capital levels. Under
the regulatory definition of brokered deposits, as of June 30, 1998 the Bank had
brokered deposits of $2.3 billion.
 
     The Bank is subject to FDIC deposit insurance assessments for the Bank
Insurance Fund ("BIF"). Each financial institution is assigned to one of three
capital groups -- well capitalized, adequately capitalized or
undercapitalized -- and further assigned to one of three subgroups within a
capital group, on the basis of supervisory evaluations by the institution's
primary federal and, if applicable, state supervisors and other information
relevant to the institution's financial condition and the risk posed to the
applicable insurance fund. The assessment rate applicable to the Bank in the
future will depend in part upon the risk assessment classification assigned to
the Bank by the FDIC and in part on the BIF assessment schedule adopted by the
FDIC. The Deposit Insurance Funds Act of 1996 ("DIFA") provides that premiums
related to deposits assessed by the BIF are to be assessed at a rate of between
0 cents and 27 cents per $100 of deposits.
 
     DIFA also separated, effective January 1, 1997, the Financing Corporation
("FICO") assessment to service the interest on its bond obligations from the BIF
and the Savings Association Insurance Fund ("SAIF") assessments. The amount
assessed on individual institutions by the FICO will be in addition to the
amount, if any, paid for deposit insurance according to the FDIC's risk-related
assessment rate schedules. FICO assessment rates for the third quarter of 1998
were set at 1.22 basis points annually for BIF-assessable deposits. (The rate
may be adjusted quarterly to reflect a change in assessment base for the BIF. By
law, the FICO rate on BIF-assessable deposits must be one-fifth the rate on
SAIF-assessable deposits until the insurance funds are merged or until January
1, 2000, whichever occurs first.)
 
REGULATION OF THE CREDIT CARD BUSINESS
 
     The relationship between the Bank and its cardholders is extensively
regulated by federal and state consumer protection laws. The Truth in Lending
Act requires credit card issuers to make certain disclosures along with their
applications and solicitations, upon opening an account and with each periodic
statement. The Truth in Lending Act also imposes certain substantive
requirements and restrictions on credit card issuers and provides cardholders
with certain rights to dispute unauthorized charges and to have their billing
errors corrected promptly. Cardholders are also given the right to have their
payments promptly credited to their accounts.
 
     The Equal Credit Opportunity Act prohibits lenders from making credit
decisions based on sex, race and marital status among others. In order to
protect borrowers from such discrimination, the Equal Credit Opportunity Act
requires credit card issuers to disclose the principal reasons they took adverse
action against an applicant or a cardholder.
 
     The Fair Credit Reporting Act generally regulates credit reporting
agencies, but also imposes some duties on credit card issuers as users of
consumer credit reports. For instance, the Fair Credit Reporting Act prohibits
the use of a consumer credit report by a credit card issuer except in connection
with a proposed business transaction with the consumer. The Fair Credit
Reporting Act also requires that credit card issuers notify consumers when they
take adverse action based upon information obtained from credit reporting
agencies.
 
     The federal regulators are authorized to impose penalties for violations of
these statutes and, in certain cases, to order the Bank to pay restitution to
injured cardholders. Cardholders may bring actions for damages for such
violations. In addition, a cardholder may be entitled to assert a violation of
these consumer protection laws by way of set-off against his obligation to pay
the outstanding credit card balance.
 
                                        9
<PAGE>   49
 
     In May, 1996, Andrew B. Spark filed a lawsuit against the Company, the Bank
and certain of its officers and its subsidiary, MBNA Marketing Systems, Inc. The
case is pending in the United States District Court for the District of
Delaware. This suit is a purported class action. The plaintiff alleges that the
Bank's advertising of its cash promotional annual percentage rate program was
fraudulent and deceptive. The plaintiff seeks unspecified damages including
actual, treble and punitive damages and attorneys' fees for an alleged breach of
contract, violation of the Delaware Deceptive Trade Practices Act and the
federal Racketeer Influenced and Corrupt Organizations Act. In February, 1998, a
class was certified. The Company believes its advertising practices are proper
under applicable federal and state law and intends to defend the action
vigorously.
 
FEDERAL FINANCIAL INSTITUTIONS EXAMINATION COUNCIL
 
     The Federal Financial Institutions Examination Council, on June 30, 1998,
proposed a revised policy statement on the classification of retail credit. If
adopted, the revised policy statement could establish, effective January 1,
2001, a uniform charge-off period of 150 days delinquency for open-end and
closed-end credit. Alternatively, the proposal also contains guidance that
would, effective January 1, 1999, standardize the methodology for implementing
the existing 180 day charge-off policy requirement for open-end credit. The
revised policy statement could also, effective January 1, 1999, provide guidance
for loans affected by bankruptcy, fraudulent activity and death; establish
standards for re-aging, extending, deferring or rewriting of past due accounts;
and broaden the circumstances under which partial payments are recognized as
full payments for purposes of determining that a loan is no longer delinquent.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The Company from time to time may offer and sell debt securities,
consisting of debentures, notes and/or other unsecured evidences of indebtedness
(the "Debt Securities"), which may be either unsecured senior Debt Securities
(the "Senior Debt Securities") or unsecured subordinated Debt Securities (the
"Subordinated Debt Securities"). The Senior Debt Securities are to be issued
under an Indenture (the "Senior Indenture") between the Company and Bankers
Trust Company, as Trustee (the "Senior Trustee"). The Subordinated Debt
Securities are to be issued under a second Indenture (the "Subordinated
Indenture") between the Company and Harris Trust and Savings Bank, as Trustee
(the "Subordinated Trustee"). Copies of the Senior Indenture and the
Subordinated Indenture have been filed with the Commission as exhibits to the
Registration Statement. The Senior Indenture and the Subordinated Indenture are
sometimes referred to collectively as the "Indentures" and the Senior Trustee
and the Subordinated Trustee are sometimes referred to collectively as the
"Trustees." The following summaries of the provisions of the Senior Debt
Securities, the Subordinated Debt Securities and the Indentures do not purport
to be complete and are subject to, and are qualified in their entirety by
reference to, all the provisions of the Indenture applicable to a particular
series of Debt Securities (the "Applicable Indenture"), including the
definitions therein of certain terms. Wherever particular Sections, Articles or
defined terms of the Applicable Indenture are referred to, it is intended that
such Sections, Articles or defined terms shall be incorporated herein by
reference. Article and Section references used herein are references to the
Applicable Indenture. Capitalized terms not otherwise defined herein shall have
the meaning given to them in the Applicable Indenture.
 
     The following sets forth certain general terms and provisions of the Debt
Securities offered hereby. The particular terms of the Debt Securities offered
by any Prospectus Supplement (the "Offered Debt Securities") will be described
in the Prospectus Supplement relating to such Offered Debt Securities (the
"Applicable Prospectus Supplement").
 
     The Company is a bank holding company, and the right of the Company to
participate as a shareholder in any distribution of assets of any subsidiary
upon its liquidation or reorganization or winding-up (and thus the ability of
Holders of the Debt Securities to benefit, as creditors of the Company, from
such distribution) is subject to the prior claims of creditors of any such
subsidiary. The Bank is subject to claims by creditors for long-term and
short-term debt obligations, including deposit liabilities, obligations for
federal funds purchased and securities sold under repurchase agreements. There
are also various legal limitations on the extent to
 
                                       10
<PAGE>   50
 
which the Bank may pay dividends or otherwise supply funds to the Company or its
affiliates. See "Regulatory Matters."
 
GENERAL
 
     The Indentures do not limit the amount of Debt Securities that may be
issued thereunder and provide that Debt Securities may be issued thereunder from
time to time in one or more series. The Debt Securities will be unsecured
obligations of the Company.
 
     The general provisions of the Indentures and the Debt Securities do not
contain any provisions that would limit the ability of the Company or its
Subsidiaries to incur indebtedness, that would require the Company or an
acquiror to repurchase Debt Securities in the event of a "change in control" or
that would afford holders of Debt Securities protection in the event of a highly
leveraged or similar transaction involving the Company or its Subsidiaries.
Reference is made to the Applicable Prospectus Supplement for information with
respect to any deletions from, modifications of or additions to the Events of
Default or covenants of the Company described below that are applicable to the
Debt Securities, including any addition of covenants or other provisions
providing event risk or similar protection.
 
     Unless otherwise indicated in the Applicable Prospectus Supplement,
principal of, premium, if any, and interest on the Debt Securities will be
payable, and the transfer of Debt Securities will be registerable, at the office
or agency of the Company in the Borough of Manhattan, The City of New York
maintained by the Company and at any other office or agency maintained by the
Company for such purpose, except that, at the option of the Company, interest
may be paid by mailing a check to the address of the Person entitled thereto as
it appears on the register for the Debt Securities. (Sections 301, 305 and 1002)
The Debt Securities will be issued only in fully registered form without coupons
and, unless otherwise indicated in the Applicable Prospectus Supplement, in
denominations of $1,000 or integral multiples thereof. (Section 302) No service
charge will be made for any registration of transfer or exchange of the Debt
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge imposed in connection therewith. (Section 305)
 
     The Applicable Prospectus Supplement will describe the following terms of
the Offered Debt Securities: (1) the title of the Offered Debt Securities; (2)
whether the Offered Debt Securities are Senior Debt Securities or Subordinated
Debt Securities; (3) any limit on the aggregate principal amount of the Offered
Debt Securities; (4) the date or dates on which the principal of the Offered
Debt Securities will mature; (5) the rate or rates (which may be fixed or
variable) at which the Offered Debt Securities will bear interest, if any, and
the date or dates from which any such interest, if any, will accrue; (6) the
dates on which such interest, if any, on the Offered Debt Securities will be
payable and the Regular Record Dates for such Interest Payment Dates; (7) the
place or places where the principal of and any premium and interest on the
Offered Debt Securities shall be payable; (8) any mandatory or optional sinking
funds or analogous provisions; (9) the date, if any, after which and the price
or prices at which the Offered Debt Securities may, pursuant to any optional or
mandatory redemption provisions, be redeemed and the other detailed terms and
provisions of any such optional or mandatory redemption provision; (10) the
obligation of the Company, if any, to redeem or repurchase the Offered Debt
Securities at the option of the Holder; (11) if other than denominations of
$1,000 and any integral multiple thereof, the denominations in which the Offered
Debt Securities shall be issuable; (12) if other than the principal amount
thereof; the portion of the principal amount of the Offered Debt Securities that
will be payable upon the declaration of acceleration of the Maturity thereof;
(13) the currency of payment of principal of and any premium and interest on the
Offered Debt Securities; (14) any index used to determine the amount of payment
of principal of and any premium and interest on the Offered Debt Securities;
(15) if the Offered Debt Securities will be issuable only in the form of a
Global Security, the Depositary or its nominee with respect to the Offered Debt
Securities and the circumstances under which the Global Security may be
registered for transfer or exchange in the name of a Person other than the
Depositary or its nominee; (16) the applicability, if any, of the provisions
described under "Defeasance and Covenant Defeasance"; (17) any additional Event
of Default, and in the case of any Offered Subordinated Debt Securities, any
additional Event of Default that would result in the acceleration of the
maturity thereof; and (18) any other terms of the Offered Debt Securities.

     Both Senior Debt Securities and Subordinated Debt Securities may be issued
as Original Issue Discount Debt Securities to be offered and sold at a
substantial discount below their stated principal amount. Federal income tax
consequences and other special considerations applicable to any such Original
Issue Discount Debt Securities will be described in the Applicable Prospectus
Supplement. "Original Issue Discount Debt Security" means any Debt Security
which provides for an amount less than the principal amount thereof to be due
and payable upon the declaration of acceleration of the Maturity thereof upon
the occurrence of an Event of Default and the continuation thereof. (Section
101)
 
SUBORDINATION OF SUBORDINATED DEBT SECURITIES
 
     Unless otherwise indicated in the Applicable Prospectus Supplement, the
following provisions shall apply to the Subordinated Debt Securities. The
following Section references are to Sections of the Subordinated Indenture.
 
     The payment of the principal of, premium, if any, and interest on the
Subordinated Debt Securities will, to the extent set forth in the Subordinated
Indenture, be subordinated in right of payment to the prior payment in full of
all Senior Indebtedness (as defined below). In certain events of insolvency, the
payment of the principal of, premium, if any, and interest on the Subordinated
Debt Securities will, to the extent set forth in the Subordinated Indenture,
also be effectively subordinated in right of payment to the prior payment in
full of all Other Financial Obligations (as defined below). Upon any payment or
distribution of assets to creditors upon any liquidation, dissolution, winding
up, reorganization, assignment for the benefit of creditors, marshalling of
assets or any bankruptcy, insolvency or similar proceedings of the Company, the
holders of all Senior Indebtedness will first be entitled to receive payment in
full of all amounts due or to become due thereon before the Holders of the
Subordinated Debt Securities will be entitled to receive any payment in respect
of the principal of, premium, if any, or interest on the Subordinated Debt
Securities. (Section 1302) If, upon any such payment or distribution of assets
to creditors, there remain, after giving effect to such subordination provisions
in favor of the holders of Senior Indebtedness, any amounts of cash, property or
securities available for payment or distribution in respect of Subordinated Debt
Securities (as defined in the Subordinated Indenture, "Excess Proceeds") and if,
at such time, any person entitled to payment pursuant to the terms of Other
Financial Obligations (as defined in the Subordinated Indenture, "Entitled
Person") has not received payment in full of all amounts due or to become due on
or in respect of such Other Financial Obligations, then such Excess Proceeds
shall first be applied to pay or provide for the payment in full of such Other
Financial Obligations before any payment or distribution may be made in respect
of the Subordinated Debt Securities. In the event of the acceleration of the
maturity of any Subordinated Debt Securities, the holders of all Senior
Indebtedness will first be entitled to receive payment in full of all amounts
due or to become due thereon before the Holders of the Subordinated Debt
Securities will be entitled to receive any payment of the principal of, premium,
if any, or interest on the Subordinated Debt Securities. (Section 1303)
Accordingly, in case of such an acceleration, all Senior Indebtedness would have
to be repaid before any payment could be made in respect of the Subordinated
Debt Securities. No payments on account of principal, premium, if any, or
interest in respect of the Subordinated Debt Securities may be made if there
shall have occurred and be continuing a default in any payment with respect to
any Senior Indebtedness, or an event of default with respect to any Senior
Indebtedness permitting the holders thereof to accelerate the maturity thereof,
or if any judicial proceeding shall be pending with respect to any such default.
(Section 1304)
 
     By reason of such subordination, in the event of the insolvency of the
Company, creditors of the Company who are not holders of Senior Indebtedness or
the Subordinated Debt Securities may recover less, ratably, than holders of
Senior Indebtedness and may recover more, ratably, than Holders of the
Subordinated Debt Securities.
 
     "Senior Indebtedness" is defined in the Subordinated Indenture to mean the
principal of, premium, if any, and interest on (i) all indebtedness of the
Company for money borrowed (including indebtedness of others guaranteed by the
Company) other than the Subordinated Debt Securities, whether outstanding on the
date of the Subordinated Indenture or thereafter created, assumed or incurred
and (ii) any amendments, renewals, extensions, modifications and refundings of
any such indebtedness, unless in either case in the instrument creating or
evidencing any such indebtedness or pursuant to which it is outstanding it is
provided
                                       12
<PAGE>   52
 
that such indebtedness is not superior in right of payment to the Subordinated
Debt Securities. (Section 101) For the purposes of this definition,
"indebtedness for money borrowed" is defined as (i) any obligation of, or any
obligation guaranteed by, the Company for the repayment of borrowed money,
whether or not evidenced by bonds, debentures, notes or other written
instruments, (ii) any deferred payment obligation of, or any such obligation
guaranteed by, the Company for the payment of the purchase price of property or
assets evidenced by a note or similar instrument, and (iii) any obligation of,
or any such obligation guaranteed by, the Company for the payment of rent or
other amounts under a lease of property or assets which obligation is required
to be classified and accounted for as a capitalized lease on the balance sheet
of the Company under generally accepted accounting principles.
 
     "Other Financial Obligations" is defined in the Subordinated Indenture to
mean all obligations of the Company to make payment pursuant to the terms of
financial instruments, such as (i) securities contracts and foreign currency
exchange contracts, (ii) derivative instruments, such as swap agreements
(including interest rate and currency and foreign exchange rate swap
agreements), cap agreements, floor agreements, collar agreements, interest rate
agreements, foreign exchange agreements, options, commodity futures contracts,
commodity options contracts and (iii) in the case of both (i) and (ii) above,
similar financial instruments other than (x) obligations on account of Senior
Indebtedness and (y) obligations on account of indebtedness for money borrowed
ranking pari passu with or subordinate to the Subordinated Debt Securities.
(Section 101)
 
     The Subordinated Indenture does not limit the amount of other indebtedness,
including Senior Indebtedness and obligations of the Company in respect of Other
Financial Obligations, that may be issued by the Company or any of its
Subsidiaries. As of June 30, 1998, the aggregate principal amount of Senior
Indebtedness outstanding for the Company was $1.9 billion.
 
RESTRICTION ON SALE OR ISSUANCE OF VOTING STOCK OF THE BANK
 
     The Senior Indenture contains a covenant by the Company that it will not,
and will not permit any Subsidiary to, sell, assign, transfer, grant a security
interest or otherwise dispose of any shares of Voting Stock, or any securities
convertible into, or options, warrants or rights to subscribe for or purchase
shares, of Voting Stock of the Bank or any Subsidiary owning, directly or
indirectly, any shares of the Bank and that it will not permit the Bank or any
Subsidiary owning, directly or indirectly, any shares of Voting Stock of the
Bank to issue any shares of the Bank's Voting Stock or any securities
convertible into, or options, warrants or rights to subscribe for or purchase
shares of the Bank's Voting Stock, except for sales, assignments, transfers,
issuances, grants of security interests or other dispositions which: (i) are for
fair market value (as determined by the Board of Directors of the Company) and
if, after giving effect thereto, the Company will own not less than 80% of the
shares of Voting Stock of the Bank or any such Subsidiary owning any shares of
Voting Stock of the Bank free and clear of any security interest; (ii) are made
(x) in compliance with an order of a court or regulatory authority of competent
jurisdiction, or (y) in compliance with a condition imposed by any such court or
authority permitting the acquisition by the Company, directly or indirectly, of
any other bank or entity the activities of which are legally permissible for a
Person such as the Company or a Subsidiary to engage in, or (z) in compliance
with an undertaking made to such an authority in connection with an acquisition
by the Company, directly or indirectly, of any bank or entity the activities of
which are legally permissible for a Person such as the Company or a Subsidiary
to engage in (provided that, in the case of clauses (y) and (z), the assets of
the bank or entity being acquired and its consolidated subsidiaries equal or
exceed 75% of the assets of the Bank or such Subsidiary owning, directly or
indirectly, any shares of Voting Stock of the Bank and its respective
consolidated subsidiaries on the date of acquisition); or (iii) are made to the
Company or any wholly owned Subsidiary. Notwithstanding the foregoing, the Bank
may be merged into or consolidated with another banking institution organized
under the laws of the United States, any State thereof or the District of
Columbia, if, after giving effect to such merger or consolidation, the Company
or any wholly owned Subsidiary owns at least 80% of the Voting Stock of such
other banking institution then issued and outstanding free and clear of any
security interest and if, immediately after giving effect thereto, no Event of
Default, and no event which, after notice or lapse of time or both, would become
an Event of Default, shall have happened and be continuing. (Section 1008)
 
                                       13
<PAGE>   53
 
     The foregoing restriction is not included in the Subordinated Indenture.
 
EVENTS OF DEFAULT
 
     The Senior Indenture (with respect to any series of Senior Debt Securities)
and, unless otherwise provided in the Applicable Prospectus Supplement, the
Subordinated Indenture (with respect to any series of Subordinated Debt
Securities) define an Event of Default as any one of the following events: (a)
default in the payment of any interest upon any Debt Security when it becomes
due and payable, and continuance of such default for a period of 30 days (in the
case of the Subordinated Indenture, whether or not payment is prohibited by the
subordination provisions); (b) default in the payment of the principal of (or
premium, if any, on) any Debt Security at its Maturity (in the case of the
Subordinated Indenture, whether or not payment is prohibited by the
subordination provisions); (c) failure to deposit any sinking fund payment when
due (in the case of the Subordinated Indenture, whether or not payment is
prohibited by the subordination provisions); (d) failure to perform any other
covenants or warranties of the Company in the Applicable Indenture (other than a
covenant or warranty included in the Applicable Indenture solely for the benefit
of a series of Debt Securities thereunder other than that series) continued for
a period of 60 days after the holders of at least 25% in principal amount of the
Outstanding Debt Securities have given written notice as provided in the
Applicable Indenture; (e) failure to pay when due the principal of, or
acceleration of, any indebtedness for borrowed money in an aggregate principal
amount exceeding $10,000,000 of the Company or of the Bank, if such acceleration
is not annulled within 10 days after written notice as provided in the
Applicable Indenture; (f) certain events of bankruptcy, insolvency or
reorganization of the Company or of the Bank; and (g) any other Event of Default
provided with respect to Debt Securities of that series. (Section 501) If an
Event of Default occurs with respect to Debt Securities of any series, the
Trustee under the Applicable Indenture shall give the Holders of Debt Securities
of such series notice of such default, provided however, that in the case of a
default described in (d) above, no such notice to Holders shall be given until
at least 30 days after the occurrence thereof. (Section 602)
 
     If an Event of Default with respect to the Senior Debt Securities of any
series at the time Outstanding occurs and is continuing, either the Senior
Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Debt Securities of that series may declare the principal amount (or,
if the Debt Securities of that series are Original Issue Discount Debt
Securities, such portion of the principal amount as may be specified in the
terms thereof) of all the Senior Debt Securities of that series to be due and
payable immediately. Payment of the principal of the Subordinated Debt
Securities may be accelerated only in the case of certain events of bankruptcy,
insolvency or reorganization of the Company. The Subordinated Trustee and the
Holders will not be entitled to accelerate the maturity of the Subordinated Debt
Securities upon the occurrence of any of the Events of Default described above
except for those described in subparagraph (f) (i.e., the bankruptcy, insolvency
or reorganization of the Company). Accordingly, there is no right of
acceleration in the case of a default in the performance of any covenant with
respect to the Subordinated Debt Securities, including the payment of interest
or principal. At any time after a declaration of acceleration with respect to
Debt Securities of any series has been made, but before a judgment or decree
based on acceleration has been obtained, the Holders of a majority in aggregate
principal amount of Outstanding Debt Securities of that series may, under
certain circumstances, rescind and annul such acceleration. (Section 502)
 
     The Indentures provide that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the Holders, unless such Holders shall have
offered to the Trustee reasonable indemnity. (Section 603) Subject to such
provisions for the indemnification of the Trustee and to certain other
conditions, the Holders of a majority in aggregate principal amount of the
Outstanding Debt Securities of any series will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Debt Securities of that series. (Section 512)
 
     No Holder of any series of Debt Securities will have any right to institute
any proceeding with respect to the Applicable Indenture or for the appointment
of a receiver or a trustee or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee under the Applicable Indenture
written notice of a
                                       14
<PAGE>   54
 
continuing Event of Default and unless the Holders of at least 25% in aggregate
principal amount of the Outstanding Debt Securities of that series shall have
made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in aggregate principal amount of the Outstanding
Debt Securities of that series a direction inconsistent with such request and
shall have failed to institute such proceeding within 60 days. (Section 507)
However, such limitations do not apply to a suit instituted by a Holder of a
Debt Security for enforcement of payment of the principal of and premium, if
any, or interest on such Debt Security on or after the respective due dates
expressed in such Debt Security. (Section 508)
 
     The Company is required under each Indenture to furnish to the Trustee
annually a statement as to the performance by the Company of certain of its
obligations under such Indenture and as to any default in such performance.
(Section 1004)
 
DEFEASANCE AND COVENANT DEFEASANCE
 
     The Indentures provide, if such provision is made applicable to the Debt
Securities of any series pursuant to Section 301 of the Applicable Indenture
(which will be indicated in the Applicable Prospectus Supplement), that the
Company may elect either (a) to defease and be discharged from any and all
obligations in respect of such Debt Securities then outstanding (including, in
the case of Subordinated Debt Securities, the provisions described under
"Subordination of Subordinated Debt Securities" and except for certain
obligations to register the transfer of or exchange of such Debt Securities,
replace stolen, lost or mutilated Debt Securities, maintain paying agencies and
hold monies for payment in trust) ("defeasance") or (b) to be released from its
obligations with respect to such Debt Securities under any covenant applicable
to such Debt Securities which is determined pursuant to Section 301 of the
Applicable Indenture to be subject to covenant defeasance and, with respect to
Senior Debt Securities, to be released from its obligations concerning the
restriction on sale or issuance of Voting Stock described under "Restriction on
Sale or Issuance of Voting Stock of the Bank" ("covenant defeasance"), and the
occurrence of an event described in clause (d) (insofar as with respect to
covenants subject to covenant defeasance) or clause (e) under "Events of
Default" above shall no longer be an Event of Default, in each case (a) or (b),
if the Company deposits, in trust, with the Trustee under the Applicable
Indenture money or U.S. Government Obligations, which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money, in an amount sufficient, without reinvestment, to pay all the
principal of (and premium, if any) and interest on such Debt Securities on the
dates such payments are due (which may include one or more redemption dates
designated by the Company) and any mandatory sinking fund or analogous payments
thereon in accordance with the terms of such Debt Securities. Such a trust may
only be established if, among other things, (i) no Event of Default or event
which with the giving of notice or lapse of time, or both, would become an Event
of Default under the Indenture shall have occurred and be continuing on the date
of such deposit, (ii) such deposit will not cause the Trustee under the
Applicable Indenture to have any conflicting interest with respect to other
securities of the Company, (iii) the Company shall have delivered an Opinion of
Counsel to the effect that the Holders will not recognize income, gain or loss
for Federal income tax purposes as a result of such deposit or defeasance and
will be subject to Federal income tax in the same manner as if such defeasance
had not occurred and (iv) in the case of Subordinated Debt Securities, no
default in the payment of principal of any Senior Indebtedness shall have
occurred or be continuing and no other event of default with respect to any
Senior Indebtedness shall have occurred and be continuing, permitting, after
notice or lapse of time or both, the acceleration thereof.
 
     The Company may exercise its defeasance option with respect to such Debt
Securities notwithstanding its prior exercise of its covenant defeasance option.
If the Company exercises its defeasance option, payment of such Debt Securities
may not be accelerated because of an Event of Default. If the Company exercises
its covenant defeasance option, payment of such Debt Securities may not be
accelerated by reference to the covenants noted under clause (b) above. In the
event the Company omits to comply with its remaining obligations with respect to
such Debt Securities under the Applicable Indenture after exercising its
covenant defeasance option and such Debt Securities are declared due and payable
because of the occurrence of any Event of Default, the amount of money and U.S.
Government Obligations on deposit with the applicable
 
                                       15
<PAGE>   55
 
Trustee may be insufficient to pay amounts due on the Debt Securities of such
series at the time of the acceleration resulting from such Event of Default.
However, the Company will remain liable in respect of such payments. (Article
Thirteen and Article Fourteen of the Senior Indenture and the Subordinated
Indenture, respectively.)
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of each of the Senior Indenture or the
Subordinated Indenture may be made by the Company and the Trustee under the
Applicable Indenture with the consent of the Holders of not less than 66 2/3% in
aggregate principal amount of the Outstanding Debt Securities of each series
issued under such Indenture and affected by the modification or amendments;
provided, however, that no such modification or amendment may, without the
consent of the Holders of all Debt Securities affected thereby, (i) change the
Stated Maturity of the principal of, or any installment of principal of or
interest on, any Debt Security; (ii) reduce the principal amount of, or the
premium, if any, or (except as otherwise provided in the Applicable Prospectus
Supplement) interest on, any Debt Security (including in the case of an Original
Issue Discount Debt Security the amount payable upon acceleration of the
maturity thereof); (iii) change the place or currency of payment of principal
of, premium, if any, or interest on any Debt Security; (iv) impair the right to
institute suit for the enforcement of any payment on any Debt Security on or at
the Stated Maturity thereof (or in the case of redemption, on or after the
Redemption Date); (v) in the case of the Subordinated Indenture, modify the
subordination provisions in a manner adverse to the Holders of the Subordinated
Debt Securities; or (vi) reduce the percentage in principal amount of
Outstanding Debt Securities of any series, the consent of whose Holders is
required for modification or amendment of the Indenture or for waiver of certain
defaults or, in the case of the Senior Indenture, for waiver of compliance with
certain provisions of such Indenture. (Section 902)
 
     The Holders of at least 66 2/3% in aggregate principal amount of the
Outstanding Senior Debt Securities of any series may, on behalf of all Holders
of that series, waive compliance by the Company with certain restrictive
provisions of the Applicable Indenture. (Section 1009) The Holders of a majority
in aggregate principal amount of the Senior Debt Securities or the Subordinated
Debt Securities may, on behalf of all Holders of the Senior Debt Securities or
the Subordinated Debt Securities, respectively, waive any past default under the
Applicable Indenture, except a default in the payment of principal, premium or
interest or in the performance of certain covenants. (Section 513)
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     Under each Indenture, the Company may consolidate with or merge into any
other corporation or convey, transfer or lease its properties and assets
substantially as an entirety to any Person without the consent of the Holders of
any of the Outstanding Debt Securities provided that (i) any successor or
purchaser is a corporation organized under the laws of the United States of
America, any State or the District of Columbia, and any such successor or
purchaser expressly assumes the Company's obligations on the Debt Securities
under a supplemental Indenture, (ii) immediately after giving effect to the
transaction no Event of Default, and no event which, after notice or lapse of
time or both, would become an Event of Default, shall have occurred and be
continuing, (iii) if properties or assets of the Company become subject to a
mortgage, pledge, lien, security interest or other encumbrance not permitted by
such Indenture, the Company or such successor Person, as the case may be, takes
such steps as shall be necessary effectively to secure the Securities equally
and ratably with (or prior to) all indebtedness secured thereby, and (iv) the
Company has delivered to the Trustee under the Applicable Indenture an Officers'
Certificate and an Opinion of Counsel stating compliance with these provisions.
(Section 801)
 
GLOBAL DEBT SECURITIES
 
     The Debt Securities of a series may be issued in the form of one or more
Global Securities that will be deposited with a Depositary or its nominee
identified in the Applicable Prospectus Supplement. In such a case, one or more
Global Securities will be issued in a denomination or aggregate denominations
equal to the portion of the aggregate principal amount of Outstanding Debt
Securities of the series to be represented by
                                       16
<PAGE>   56
 
such Global Security or Securities. Unless and until it is exchanged in whole or
in part for Debt Securities in definitive registered form, a Global Security may
not be registered for transfer or exchange except as a whole by the Depositary
for such Global Security to a nominee for such Depositary and except in the
circumstances described in the Applicable Prospectus Supplement. (Sections 204
and 305)
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Debt Securities to be represented by a Global Security
will be described in the Applicable Prospectus Supplement.
 
CONCERNING THE TRUSTEES
 
     Bankers Trust Company and Harris Trust and Savings Bank are Trustees under
the Senior Indenture and the Subordinated Indenture, respectively. In the normal
course of business, the Company and its subsidiaries conduct banking
transactions with the Trustees, and the Trustees conduct banking transactions
with the Company and its subsidiaries. Bankers Trust Company serves as trustee
for several of the trusts established in connection with certain of the Bank's
asset securitizations.
 
                         DESCRIPTION OF PREFERRED STOCK
 
     The following summary contains a description of the general terms of the
preferred stock, par value $.01 per share (the "Preferred Stock") to which any
Prospectus Supplement may relate. Certain terms of any series of the Preferred
Stock offered by any Prospectus Supplement will be described in the Prospectus
Supplement relating to such series of the Preferred Stock. If so indicated in
the Prospectus Supplement, the terms of any such series, including any
Depositary Shares (as defined below) issued in respect thereof, may differ from
the terms set forth below. The description of certain provisions of the
Preferred Stock set forth below and in any Prospectus Supplement does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the Company's Articles of Incorporation and the articles
supplementary to the Company's Articles of Incorporation which will be filed
with the Commission in connection with the offering of such series of Preferred
Stock.
 
GENERAL
 
     Under the Company's Articles of Incorporation, the Board of Directors of
the Company is authorized, without further shareholder action, to provide for
the issuance of shares of Preferred Stock, par value $.01 per share, in one or
more series, with such terms, including preferences, conversion and other
rights, voting power, restrictions, limitations as to dividends, qualifications
and terms and conditions of redemption, as shall be established in or pursuant
to the resolution or resolutions providing for the issue thereof to be adopted
by the Board of Directors. Currently, under the Company's Articles of
Incorporation, 20,000,000 shares are classified as Preferred Stock. The
Company's Board of Directors has authority, without further shareholder
approval, to reclassify authorized but unissued shares of any stock as Preferred
Stock or other stock having preferred dividend and voting rights and other
characteristics determined by the Board of Directors. Prior to the issuance of
each series of Preferred Stock, the Board of Directors (as used herein the term
"Board of Directors" includes any duly authorized committee thereof) will adopt
resolutions creating and designating such series as a series of Preferred Stock.
As of June 30, 1998, the Company has outstanding 4,547,882 shares of 7 1/2%
Cumulative Preferred Stock, Series A, and 4,026,000 shares of Adjustable Rate
Cumulative Preferred Stock, Series B.
 
     The Preferred Stock shall have the dividend, liquidation, and voting rights
set forth below, unless otherwise provided in the Prospectus Supplement relating
to a particular series of the Preferred Stock. Reference is made to the
Prospectus Supplement relating to the particular series of the Preferred Stock
offered thereby for specific terms, including: (i) the designation of such
Preferred Stock and the number of shares offered; (ii) the amount of liquidation
preference per share; (iii) the price at which such Preferred Stock will be
issued; (iv) the dividend rate (or method of calculation), the dates on which
dividends shall be payable, whether such dividends shall be cumulative or
noncumulative and, if cumulative, the dates from which dividends shall commence
to cumulate; (v) any redemption or sinking fund provisions of such Preferred
Stock; (vi) whether the Company has elected to offer Depositary Shares (as
defined below); and (vii) any
                                       17
<PAGE>   57
 
additional voting, dividend, liquidation, redemption, sinking fund and other
rights, preferences, privileges, limitations and restrictions of such Preferred
Stock.
 
     The Preferred Stock will, when issued, be fully paid and nonassessable and
have no preemptive rights. Unless otherwise specified in the Prospectus
Supplement relating to a particular series of the Preferred Stock, each series
of the Preferred Stock will rank on a parity as to dividends and liquidation
rights in all respects with each other series of the Preferred Stock.
 
RANK
 
     Any series of the Preferred Stock will, with respect to dividend rights and
rights on liquidation, winding up and dissolution rank (i) senior to all classes
of Common Stock and to all equity securities issued by the Company the terms of
which specifically provide that such equity securities will rank junior to the
Preferred Stock (collectively referred to as the "Junior Securities"); (ii) on a
parity with all equity securities issued by the Company the terms of which
specifically provide that such equity securities will rank on a parity with the
Preferred Stock (collectively referred to as the "Parity Securities"); and (iii)
junior to all equity securities issued by the Company the terms of which
specifically provide that such equity securities will rank senior to the
Preferred Stock.
 
DIVIDEND RIGHTS
 
     Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of funds
of the Company legally available therefor, cash dividends at such rates and on
such dates as are set forth in the Prospectus Supplement relating to such series
of the Preferred Stock. Such rate may be fixed or variable or both. Each such
dividend will be payable to the holders of record as they appear on the stock
record books of the Company (or, if applicable, the records of the Depositary
referred to below under "Depositary Shares") on such record dates as will be
fixed by the Board of Directors of the Company or a duly authorized committee
thereof. Dividends on any series of the Preferred Stock may be cumulative or
noncumulative, as provided in the Prospectus Supplement relating thereto. The
Company's ability to pay dividends on its Preferred Stock is subject to policies
established by the Federal Reserve Board. See "Regulatory Matters -- Dividend
Restrictions."
 
     No full dividends may be declared or paid or funds set apart for the
payment of dividends on any Parity Securities unless dividends shall have been
paid or set apart for such payment on the Preferred Stock. If full dividends are
not so paid, the Preferred Stock shall share dividends pro rata with the Parity
Securities. No dividends may be declared or paid or funds set apart for the
payment of dividends on any Junior Securities unless full cumulative dividends
for all dividend periods terminating on or prior to the date of such declaration
or payment shall have been paid or declared and a sum sufficient for the payment
thereof set apart for payment on the Preferred Stock.
 
     Each series of Preferred Stock will be entitled to dividends as described
in the Prospectus Supplement relating to such series, which may be based upon
one or more methods of determination. Different series of the Preferred Stock
may be entitled to dividends at different rates or based upon different methods
of determination.
 
VOTING RIGHTS
 
     Except as indicated in the Prospectus Supplement relating to a particular
series of Preferred Stock, or except as expressly required by applicable law,
the holders of the Preferred Stock will not be entitled to any voting rights.
 
     Under regulations adopted by the Federal Reserve Board if the holders of
shares of any series of Preferred Stock of the Company become entitled to vote
for the election of directors because dividends on such series are in arrears
such series may then be deemed a "class of voting securities" and a holder of
25% or more of such series (or a holder of 5% or more if it otherwise exercises
a "controlling influence" over the Company) may then be subject to regulation as
a bank holding company in accordance with the Bank Holding Company
 
                                       18

Act. In addition, at such time as such series is deemed a class of voting
securities, (i) any other bank holding company may be required to obtain the
approval of the Federal Reserve Board under the Bank Holding Company Act to
acquire or retain 5% or more of such series and (ii) any person other than a
bank holding company may be required to obtain the approval of the Federal
Reserve Board under the Change in Bank Control Act or the Bank Holding Company
Act to acquire or retain 10% or more of such series.
 
RIGHTS UPON LIQUIDATION
 
     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of each series of Preferred Stock will be
entitled to receive out of assets of the Company available for distribution to
shareholders, before any distribution of assets is made to holders of Junior
Securities, including common stock, liquidating distributions in the amount set
forth in the Prospectus Supplement relating to such series of the Preferred
Stock plus an amount equal to accrued and unpaid dividends for the then-current
dividend period and, if such series of the Preferred Stock is cumulative, for
all dividend periods prior thereto, all as set forth in the Prospectus
Supplement with respect to such shares. If upon any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the amounts payable with
respect to the Preferred Stock of any series and any other Parity Securities are
not paid in full, the holders of the Preferred Stock of such series and the
Parity Securities will share ratably in any such distribution of assets of the
Company in proportion to the full liquidation preferences to which each is
entitled. After payment of the full amount of the liquidation preference to
which they are entitled, the holders of such series of Preferred Stock will not
be entitled to any further participation in any distribution of assets of the
Company.
 
     Because the Company is a bank holding company, its rights, the rights of
its creditors and of its stockholders, including the holders of the shares of
the Preferred Stock offered hereby, to participate in the assets of any
subsidiary, including the Bank, upon the latter's liquidation or
recapitalization may be subject to the prior claims of the subsidiary's
creditors except to the extent that the Company may itself be a creditor with
recognized claims against the subsidiary.
 
REDEMPTION
 
     A series of the Preferred Stock may be redeemable, in whole or in part, at
the option of the Company or the holder thereof, and may be subject to mandatory
redemption pursuant to a sinking fund, in each case upon terms, at the times and
at the redemption prices set forth in the Prospectus Supplement relating to such
series.
 
     In the event of partial redemptions of Preferred Stock, whether by
mandatory or optional redemption, the shares to be redeemed will be determined
by lot or pro rata, as may be determined by the Board of Directors of the
Company, a committee thereof or by any other method determined to be equitable
by the Board of Directors.
 
     On or after a redemption date, unless the Company defaults in the payment
of the redemption price, dividends will cease to accrue on shares of Preferred
Stock called for redemption and all rights of holders of such shares will
terminate except for the right to receive the redemption price.
 
     Under current regulations, bank holding companies may exercise an option to
redeem shares of preferred stock included as Tier 1 capital, or exchange such
preferred stock for debt securities, without the prior approval of the Federal
Reserve Board, if the bank holding company will remain well capitalized,
received a composite rating of 1 or 2 of its most recent BOPEC inspection and is
not the subject of any unresolved supervisory issues.
 
CONVERSION
 
     The Prospectus Supplement for any series of the Preferred Stock will state
the terms, if any, on which shares of that series are convertible into other
securities of the Company.

DEPOSITARY SHARES
 
     General.  The Company may, at its option, elect to offer receipts for
fractional interests ("Depositary Shares") in Preferred Stock, rather than full
shares of Preferred Stock. In such event, receipts ("Depositary Receipts") for
Depositary Shares, each of which will represent a fraction (to be set forth in
the Prospectus Supplement relating to a particular series of Preferred Stock) of
a share of a particular series of Preferred Stock, will be issued as described
below.
 
     The shares of any series of Preferred Stock represented by Depositary
Shares will be deposited under a Deposit Agreement (the "Deposit Agreement")
between the Company and the depositary named in the Prospectus Supplement (the
"Depositary"). Subject to the terms of the Deposit Agreement, each owner of a
Depositary Share will be entitled, in proportion to the applicable fraction of a
share of Preferred Stock represented by such Depositary Share, to all the rights
and preferences of the Preferred Stock represented thereby (including dividend,
voting, redemption, subscription and liquidation rights). The following summary
of certain provisions of the Deposit Agreement does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the Deposit Agreement, including the definitions therein of
certain terms. Whenever particular sections of the Deposit Agreement are
referred to, it is intended that such sections shall be incorporated herein by
reference. Copies of the forms of Deposit Agreement and Depositary Receipt are
filed as an exhibit to the Registration Statement of which this Prospectus is a
part, and the following summary is qualified in its entirety by reference to
such exhibits.
 
     Dividends and Other Distributions.  The Depositary will distribute all cash
dividends or other cash distributions received in respect to the Preferred Stock
to the record holders of Depositary Shares relating to such Preferred Stock in
proportion to the numbers of such Depositary Shares owned by such holders.
(Section 4.01)
 
     In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record holders of Depositary Shares in
an equitable manner, unless the Depositary determines that it is not feasible to
make such distribution, in which case the Depositary may sell such property and
distribute the net proceeds for such sale to such holders. (Section 4.02)
 
     Redemption of Depositary Shares.  If a series of Preferred Stock
represented by Depositary Shares is subject to redemption, the Depositary Shares
will be redeemed from the proceeds received by the Depositary resulting from the
redemption, in whole or in part, of such series of Preferred Stock held by the
Depositary. The redemption price per Depositary Shares will be equal to the
applicable fraction of the redemption price per share payable with respect to
such series of the Preferred Stock. Whenever the Company redeems shares of
Preferred Stock held by the Depositary, the Depositary will redeem as of the
same redemption date the number of Depositary Shares representing shares of
Preferred Stock so redeemed. If fewer than all the Depositary Shares are to be
redeemed, the Depositary Shares to be redeemed will be selected by lot, pro rata
or by any other equitable method as may be determined by the Depositary.
(Section 2.08)
 
     Voting the Preferred Stock.  Upon receipt of notice of any meeting at which
the holders of the Preferred Stock are entitled to vote, the Depositary will
mail the information contained in such notice of meeting to the record holders
of the Depositary Shares relating to such Preferred Stock. Each record holder of
such Depositary Shares on the record date (which will be the same date as the
record date for the Preferred Stock) will be entitled to instruct the Depositary
as to the exercise of the voting rights pertaining to the amount of the
Preferred Stock represented by such holder's Depositary Shares. The Depositary
will endeavor, insofar as practicable, to vote the amount of the Preferred Stock
represented by such Depositary Shares in accordance with such instructions, and
the Company will agree to take all reasonable action which may be deemed
necessary by the Depositary in order to enable the Depositary to do so. The
Depositary will abstain from voting shares of the Preferred Stock to the extent
it does not receive specific instructions from the holder of Depositary Shares
representing such Preferred Stock. (Section 4.05)
 
     Amendment and Termination of the Deposit Agreement.  The form of Depositary
Receipt evidencing the Depositary Shares and any provision of the Deposit
Agreement may at any time be amended by agreement between the Company and the
Depositary. However, any amendment which materially and adversely alters
 
                                       20
<PAGE>   60
 
the rights of the holders of Depositary Shares will not be effective unless such
amendment has been approved by the holders of at least a majority of the
Depositary Shares then outstanding. (Section 6.01) The Deposit Agreement will
only terminate if (i) all outstanding Depositary Shares have been redeemed or
(ii) there has been a final distribution in respect of the Preferred Stock in
connection with any liquidation, dissolution or winding up of the Company and
such distribution has been distributed to the holders of Depositary Receipts.
(Section 6.02)
 
     Charges of Depositary.  The Company will pay all transfer and other taxes
and governmental charges arising solely from the existence of the depositary
arrangements. The Company will pay charges of the Depositary in connection with
the initial deposit of the Preferred Stock and issuance of Depositary Receipts,
all withdrawals of shares of Preferred Stock by owners of Depositary Shares and
any redemption of the Preferred Stock. Holders of Depositary Receipts will pay
other transfer and other taxes and governmental charges and such other charges
as are expressly provided in the Deposit Agreement to be for their accounts.
(Section 5.07)
 
     Resignation and Removal of Depositary.  The Depositary may resign at any
time by delivering to the Company notice of its election to do so, and the
Company may at any time remove the Depositary, any such resignation or removal
to take effect upon the appointment of a successor Depositary and its acceptance
of such appointment. Such successor Depositary must be appointed within 60 days
after delivery of the notice of resignation or removal and must be a bank or
trust company having its principal office in the United States and having a
combined capital and surplus of at least $50,000,000. (Section 5.04)
 
     Miscellaneous.  The Depositary will forward all reports and communications
from the Company which are delivered to the Depositary and which the Company is
required or otherwise determines to furnish to the holders of the Preferred
Stock. (Section 4.07)
 
     Neither the Depositary nor the Company will be liable under the Deposit
Agreement to holders of Depositary Receipts other than for its negligence,
willful misconduct or bad faith. Neither the Company nor the Depositary will be
obligated to prosecute or defend any legal proceeding in respect of any
Depositary Shares or Preferred Stock unless satisfactory indemnity is furnished.
The Company and the Depositary may rely upon written advice of counsel or
accountants, or upon information provided by persons presenting Preferred Stock
for deposit, holders of Depositary Receipts or other persons believed to be
competent and on documents believed to be genuine. (Section 5.03)
 
                          DESCRIPTION OF COMMON STOCK
 
     The following summary does not purport to be complete and is subject in all
respects to the applicable provisions of the Maryland General Corporation Law
and the Company's charter and by-laws. See "Available Information."
 
     The Company is authorized to issue up to 1,500,000,000 shares of common
stock, $.01 par value per share (the "Common Stock"). At June 30, 1998, the
Company had issued and outstanding 751,781,250 shares of Common Stock.
 
     Holders of Common Stock of the Company are entitled to receive, pro rata,
dividends declared by the Board of Directors out of funds legally available
therefor. The ability of the Company to pay dividends to its stockholders may be
limited by federal law. See "Regulatory Matters." In the event of any
liquidation, dissolution or winding up of the Company, holders of Common Stock
are entitled to share ratably in the assets available for distribution to
stockholders.
 
     Each share of Common Stock is entitled to one vote on each matter submitted
to a vote of stockholders. There is no right of cumulative voting in connection
with the election of directors. The Common Stock has no conversion rights and is
not redeemable. All outstanding shares of Common Stock are, and the shares sold
in the offerings will be when issued, fully paid and nonassessable. A
stockholder of the Company has no preemptive rights to subscribe for additional
shares of stock or other securities of the Company except as may be granted by
the Company's board of directors.
 
                                       21
<PAGE>   61
 
                            DESCRIPTION OF WARRANTS
 
     The Company may issue warrants to purchase Debt Securities, Preferred
Stock, Depositary Shares and Common Stock (the "Warrants"). Warrants may be
issued independently of or together with any other Securities and may be
attached to or separate from such Securities. Each series of Warrants will be
issued under a separate Warrant Agreement (each a "Warrant Agreement") to be
entered into between the Company and a Warrant Agent ("Warrant Agent"). The
Warrant Agent will act solely as an agent of the Company in connection with the
Warrants of such series and will not assume any obligation or relationship of
agency or trust for or with holders or beneficial owners of Warrants. The
following sets forth certain general terms and provisions of the Warrants
offered hereby. Further terms of the Warrants and the applicable Warrant
Agreement will be set forth in the applicable Prospectus Supplement.
 
     The applicable Prospectus Supplement will describe the following terms,
where applicable, of the Warrants in respect of which this Prospectus is being
delivered: (i) the title of such Warrants; (ii) the aggregate number of such
Warrants; (iii) the price or prices at which such Warrants will be issued; (iv)
the designation, aggregate principal amount and terms of the securities
purchasable upon exercise of such Warrants; (v) the designation and terms of the
Securities with which such Warrants are issued and the number of such Warrants
issued with each such security; (vi) if applicable, the date on and after which
such Warrants and the related securities will be separately transferable; (vii)
the price at which the securities purchasable upon exercise of such Warrants may
be purchased; (viii) the date on which the right to exercise such Warrants shall
commence and the date on which such right shall expire; (ix) the minimum or
maximum amount of such Warrants which may be exercised at any one time; (x)
information with respect to book-entry procedures, if any; (xi) a discussion of
certain Federal income tax considerations; and (xii) any other terms of such
Warrants, including terms, procedures and limitations relating to the exchange
and exercise of such Warrants.
 
        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
     The Company may issue stock purchase contracts ("Stock Purchase
Contracts"), representing contracts obligating holders to purchase from the
Company, and the Company to sell to the holders, a specified number of shares of
Common Stock at a future date or dates. The price per share of Common Stock may
be fixed at the time the Stock Purchase Contracts are issued or may be
determined by reference to a specific formula set forth in the Stock Purchase
Contracts. The Stock Purchase Contracts may be issued separately or as a part of
stock purchase units ("Stock Purchase Units") consisting of a Stock Purchase
Contract and Debt Securities or debt obligations of third parties, including
U.S. Treasury securities, securing the holders' obligations to purchase the
Common Stock under the Stock Purchase Contracts. The Stock Purchase Contracts
may require the Company to make periodic payments to the holders of the Stock
Purchase Units or vice-versa, and such payments may be unsecured or prefunded on
some basis. The Stock Purchase Contracts may require holders to secure their
obligations thereunder in a specified manner.
 
     The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell Securities to or through underwriters or dealers, and
also may sell Securities directly to other purchasers or through agents. Each
Prospectus Supplement will describe the method of distribution of the Securities
being offered thereby.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, or at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.
 
     In connection with the sale of Securities, underwriters may receive
compensation from the Company or from purchasers of Securities for whom they may
act as agents in the form of discounts, concessions or
 
                                       22
<PAGE>   62
 
commissions. Underwriters may sell Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agents. Underwriters, dealers and agents that participate
in the distribution of Securities may be deemed to be underwriters, and any
discounts or commissions received by them from the Company and any profit on the
resale of Securities by them may be deemed to be underwriting discounts and
commissions, under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from the Company will be
described, in the Prospectus Supplement.
 
     If so indicated in the Applicable Prospectus Supplement and subject to
existing market conditions, the Company will authorize underwriters or other
persons acting as the Company's agents to solicit offers by certain institutions
to purchase Offered Debt Securities from the Company pursuant to contracts
providing for payment and delivery on a future date. Institutions with which
such contracts may be made include but are not limited to commercial and savings
banks, insurance companies, pension funds, investment companies, educational and
charitable institutions and others, but in all cases such institutions must be
approved by the Company. The obligations of any purchaser under any such
contract will be subject to the condition that the purchase of the Offered Debt
Securities shall not at the time of delivery be prohibited under the laws of the
jurisdiction to which such purchaser is subject. The underwriters and such other
agents will not have any responsibility in respect of the validity or
performance of such contracts.
 
     Underwriters and agents who participate in the distribution of Securities
may be entitled under agreements which may be entered into by the Company to
indemnification by the Company against certain liabilities, including
liabilities under the Securities Act.
 
     Except as indicated in the Applicable Prospectus Supplement, the Securities
are not expected to be listed on a securities exchange, except for the Common
Stock, which is listed on the New York Stock Exchange, and any underwriters or
dealers will not be obligated to make a market in Securities. The Company cannot
predict the activity or liquidity of any trading in the Securities.
 
                             VALIDITY OF SECURITIES
 
     The validity of the Securities will be passed upon for the Company by John
W. Scheflen, Executive Vice President, General Counsel and Secretary of the
Company, and for any underwriters, dealers or agents by Simpson Thacher &
Bartlett, New York, New York. Simpson Thacher & Bartlett will rely on the
opinion of Mr. Scheflen as to matters of Maryland law and Mr. Scheflen will rely
on the opinion of Simpson Thacher & Bartlett as to matters of New York law. Mr.
Scheflen owns beneficially in excess of 100,000 shares of Common Stock,
including options exercisable within sixty days under the Company's 1991 Long
Term Incentive Plan. Simpson Thacher & Bartlett regularly performs legal
services for the Company and its subsidiaries.
