                                  RISK FACTORS

    Your investment in the notes involves certain risks. In consultation with
your own financial and legal advisers, you should carefully consider, among
other matters, the following discussion of risks before deciding whether an
investment in the notes is suitable for you. The notes are not an appropriate
investment for you if you are unsophisticated with respect to the significant
components of the notes.

AN INVESTMENT IN INDEXED NOTES PRESENTS SIGNIFICANT RISKS NOT ASSOCIATED WITH
  OTHER TYPES OF NOTES

    Indexed notes may present a high level of risk, and you may lose your entire
investment if you purchase them. If we issue indexed notes, we will describe
more fully certain risks associated with those particular indexed notes in the
applicable pricing supplement.

    INVESTORS IN INDEXED NOTES COULD LOSE PRINCIPAL OR INTEREST

    The principal amount of an indexed note payable at maturity and/or the
amount of interest payable on an interest payment date will be determined by
reference to one or more of the following, each of which is an "index":

    - currencies, including baskets of currencies;

    - commodities, including baskets of commodities;

    - securities, including baskets of securities; or

    - any other index or financial measure.

    The direction and magnitude of the change in the value of the relevant index
will determine either or both the principal amount of an indexed note payable at
maturity or the amount of interest payable on an interest payment date. The
terms of a particular indexed note may or may not include a guaranteed return of
a percentage of the face amount at maturity or a minimum interest rate.
Accordingly, if you invest in an indexed note, you may lose all or a portion of
your principal and may receive no interest on the note.

    THE ISSUER OF AN INDEX SECURITY COULD TAKE ACTIONS THAT ADVERSELY AFFECT AN
     INDEXED NOTE

    The issuer of a security that serves as an index or part of an index for an
indexed note will, unless otherwise provided in the applicable pricing
supplement, have no involvement in the offer and sale of the note and no
obligations to the holder of the note. The issuer may take actions, such as a
merger or sale of assets, without regard to the interests of the holder. Any of
these actions could adversely affect the value of a note indexed to that
security.

    AN INDEXED NOTE MAY BE LINKED TO A VOLATILE INDEX, WHICH COULD HURT YOUR
     INVESTMENT

    Certain indices are highly volatile, which means that their value may change
significantly, up or down, over a short period of time. The expected principal
amount payable at maturity of, or the interest rate on, an indexed note that is
based on a volatile index may vary substantially from time to time. Because the
principal amount payable at the maturity of, or interest payable on, an indexed
note is generally calculated based on the value of the relevant index on a
specified date or over a limited period of time, volatility in the index
increases the risk that the return on the indexed note may be adversely affected
by a fluctuation in the level of the relevant index.

    The volatility of an index may be affected by political or economic events,
including governmental actions, or by the activities of participants in the
relevant markets. Any of these could adversely affect the value of an indexed
note.

                                      S-3
<Page>
    AN INDEX TO WHICH A NOTE IS LINKED COULD BE CHANGED OR BECOME UNAVAILABLE

    Certain indices reference several different currencies, commodities,
securities or other financial instruments. The compiler of such an index
typically reserves the right to alter the composition of the index and the
manner in which the value of the index is calculated. Such an alteration may
result in a decrease in the value of or return on an indexed note which is
linked to that index.

    An index could become unavailable due to various factors, such as war,
natural disasters, cessation of publication of the index, or suspension of or
disruption in trading in any currency, commodity, security or other financial
instrument comprising or underlying the index. If an index becomes unavailable,
the determination of principal of or interest on an indexed note may be delayed
or an alternative method may be used to determine the value of the unavailable
index. Alternative methods of valuation are generally intended to produce a
value similar to the value resulting from reference to the unavailable index.
However, it is unlikely that an alternative method of valuation will produce
values identical to those which would be produced were the original index
available. An alternative method of valuation may result in a decrease in the
value of or return on an indexed note.

    Certain indexed notes may be linked to unusual and/or recently developed
indices. These characteristics may make it difficult to anticipate the
volatility of the index or other risks to which such a note is subject. In
addition, trading in such indices or instruments underlying such indices may be
infrequent or sporadic, which could increase the volatility of such indices and
decrease the value of or return on indexed notes linked to them.

    THE TAX TREATMENT OF INDEXED NOTES MAY BE UNCLEAR

    The treatment of indexed notes for United States Federal income tax purposes
is often unclear due to the absence of any authority specifically addressing the
issues presented by any particular indexed note. Accordingly, you should consult
your tax adviser regarding the Federal income tax consequences of purchasing an
indexed note.

    INFORMATION ABOUT INDICES MAY NOT BE INDICATIVE OF FUTURE PERFORMANCE

    If we issue an indexed note, the applicable pricing supplement may include
historical information about the relevant index. Any information about indices
that we may provide will be furnished as a matter of information only, and you
should not regard the information as indicative of the range of, or trends in,
fluctuations in the relevant index that may occur in the future.

    WE MAY HAVE CONFLICTS OF INTEREST REGARDING AN INDEXED NOTE

    We or one or more of our affiliates may have conflicts of interest with
respect to some indexed notes. For example, we or one or more of our affiliates
may engage in trading, including trading for hedging purposes, for our
proprietary accounts or for other accounts under management, in indexed notes,
in the currencies, commodities, securities or other financial instruments on
which an index is based, or in other derivative instruments related to the
index. These trading activities could adversely affect the value of indexed
notes. We or one or more of our affiliates may also issue securities or
derivative instruments that are linked to the same index as one or more indexed
notes. Introducing competing products into the marketplace in this manner could
adversely affect the value of an indexed note.

    To the extent that one or more of our affiliates calculates or compiles a
particular index, it may have considerable discretion in performing the
calculation or compilation. Exercising discretion in this manner could adversely
affect the value of or the rate of return on an indexed note based on such
index.

                                      S-4
<Page>
REDEMPTION MAY ADVERSELY AFFECT YOUR RETURN ON THE NOTES

    If your notes are redeemable at our option or are otherwise subject to
mandatory redemption, we may, in the case of optional redemption, or must, in
the case of mandatory redemption, redeem your notes at times when prevailing
interest rates may be relatively low. In these situations, you generally will
not be able to reinvest the redemption proceeds in a comparable security at an
effective interest rate as high as that of the notes being redeemed.

THERE MAY NOT BE ANY TRADING MARKET FOR YOUR NOTES; MANY FACTORS AFFECT THE
TRADING MARKET AND VALUE OF YOUR NOTES

    Upon issuance, your notes will not have an established trading market. We
cannot assure you that a trading market for your notes will ever develop or be
maintained if developed. Many factors independent of our creditworthiness may
affect the trading market for, and trading value of, your notes. These factors
include:

    - the complexity and volatility of the index or formula applicable to your
      notes,

    - the method of calculating the principal, premium and interest in respect
      of your notes,

    - the time remaining to the maturity of your notes,

    - the outstanding amount of your notes,

    - any redemption features of your notes,

    - the amount of other securities linked to the index or formula applicable
      to your notes, and

    - the level, direction and volatility of market interest rates generally.

    In addition, notes that are designed for specific investment objectives or
strategies often experience a more limited trading market and more price
volatility. There may be a limited number of buyers when you decide to sell your
notes. This may affect the price you receive for your notes or your ability to
sell your notes at all. You should not purchase notes unless you understand and
know that you can bear the related investment risks.

OUR CREDIT RATINGS MAY NOT REFLECT ALL RISKS OF AN INVESTMENT IN THE NOTES

    Our credit ratings are an assessment of independent rating agencies of our
ability to pay our obligations. Consequently, real or anticipated changes in our
credit ratings will generally affect the market value of your notes. Our credit
ratings, however, may not reflect the potential impact of risks related to
structure, market or other factors discussed above on the value of your notes.

                            DESCRIPTION OF THE NOTES

    FOR EACH NOTE WE OFFER AND SELL, WE WILL PREPARE A PRICING SUPPLEMENT TO
THIS PROSPECTUS SUPPLEMENT AND ACCOMPANYING PROSPECTUS. THE PRICING SUPPLEMENT
WILL INCLUDE THE SPECIFIC TERMS OF THE NOTE OR NOTES TO WHICH IT RELATES AND MAY
INCLUDE MODIFICATIONS OF OR ADDITIONS TO THE MORE GENERAL TERMS DESCRIBED IN
THIS PROSPECTUS SUPPLEMENT AND ACCOMPANYING PROSPECTUS. THROUGHOUT THE FOLLOWING
DISCUSSION OF THE TERMS OF THE NOTES, WE WILL REFER TO VARIOUS "SPECIFIED" TERMS
OF THE NOTES, AND, UNLESS OTHERWISE STATED, THOSE REFERENCES MEAN THE TERMS
SPECIFIED IN THE APPLICABLE PRICING SUPPLEMENT AND THE NOTES. EXCEPT AS
OTHERWISE SPECIFIED IN THE PRICING SUPPLEMENT RELATING TO A NOTE, THE NOTE WILL
HAVE THE TERMS DESCRIBED BELOW AND IN THE ACCOMPANYING PROSPECTUS UNDER THE
CAPTION "DESCRIPTION OF DEBT SECURITIES". IF THE PRICING SUPPLEMENT RELATING TO
THE NOTE SPECIFIES DIFFERENT TERMS, THEN THE NOTE WILL HAVE THE TERMS SPECIFIED
IN THE PRICING SUPPLEMENT.

TERMS OF THE NOTES

    The notes will be issued as a series of debt securities under the indenture
described in the accompanying prospectus. All of the debt securities, including
the notes, issued and to be issued under the indenture will be our unsecured
general obligations and will rank equally with all of our other unsecured and
unsubordinated indebtedness from time to time outstanding.

    The indenture does not limit the aggregate principal amount of debt
securities that we may issue. We have issued debt securities under the indenture
in the past and we may, from time to time, without the consent of the holders of
the notes, provide for the issuance of notes or other debt securities under the
indenture in addition to the $3,500,000,000 aggregate principal amount of notes
offered by this prospectus supplement. The aggregate principal amount of notes
that may be offered and sold by this prospectus supplement will be reduced if we
sell other debt securities under the registration statement of which this
prospectus supplement and the accompanying prospectus are a part.

    We will offer the notes on a continuing basis. They will mature on a day
nine months or more from the date of issue, as selected by the purchaser and
agreed to by us. Each interest-bearing note will bear interest at either a fixed
or floating rate. Some notes may bear no interest or may bear interest at a rate
substantially below prevailing market rates. In either situation, these notes
may be issued at significant discounts from the principal amounts payable upon
their Maturity. When we use the term "Maturity" with respect to any note, we
mean the regularly scheduled maturity of that note or any earlier date on which
the principal (or an installment of principal) becomes due and payable as a
result of:

    - mandatory redemption or our exercise of an option to redeem the note;

    - the noteholder's exercise of an option for early repayment of the note;

    - acceleration of the note in accordance with the indenture; or

    - any other reason.

    We may change from time to time the interest rates, interest rate bases and
other variable terms of the notes offered by this prospectus supplement, but no
change will affect any note already issued or as to which we have accepted an
offer to purchase. The interest rates we offer with respect to the notes may
differ depending upon, among other things, the aggregate principal amount of
notes purchased in any transaction. At any given time, we may offer notes with
different interest rates or other variable terms to different investors. We may
"reopen" a previous tranche of notes and issue additional notes of that tranche.

    We will issue each note in fully registered form in a denomination of $1,000
or an integral multiple of $1,000. We may issue notes either in book-entry form
or in certificated form. Notes in book-entry form may be transferred or
exchanged only through a participating member of the depositary for the

                                      S-6
<Page>
notes, which will be The Depository Trust Company, also known as DTC, unless
otherwise specified. See "--Book-Entry Notes" in this prospectus supplement and
"Description of Debt Securities--Global Debt Securities" in the accompanying
prospectus. Notes in certificated form may be transferred or exchanged at the
corporate trust office of the trustee. We will not impose a service charge for
any transfer or exchange of notes, but we may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
with any transfer or exchange, other than exchanges pursuant to the indenture
not involving any transfer.

    We will pay the principal of, and premium and interest, if any, on, notes in
book-entry form to the depositary or its nominee. See "--Book-Entry Notes" in
this prospectus supplement and "Description of Debt Securities--Global Debt
Securities" in the accompanying prospectus. In the case of notes in certificated
form:

    - We will pay the principal and premium, if any, due at Maturity in
      immediately available funds upon presentation of the note and, in the case
      of any repayment on an optional repayment date, upon submission of a duly
      completed election form if and as required by the provisions described
      below, at the corporate trust office of the trustee in the Borough of
      Manhattan, The City of New York, or at any other place we may designate.

    - We will pay interest due at Maturity to the same person to whom we pay the
      principal of the note.

    - We will pay interest due other than at Maturity at the corporate trust
      office of the trustee or, at our option, by check mailed to the address of
      the person entitled to receive payment as the address appears in the
      security register. Notwithstanding the immediately preceding sentence, a
      holder of $1,000,000 or more in aggregate principal amount of notes in
      certificated form, whether having identical or different terms and
      provisions, having the same interest payment dates will, at our option, be
      entitled to receive interest payments, other than at Maturity, by wire
      transfer of immediately available funds if appropriate wire transfer
      instructions have been received in writing by the trustee not less than 15
      days prior to the applicable interest payment date. Any wire instructions
      received by the trustee shall remain in effect until revoked by the
      holder.

REDEMPTION AT OUR OPTION

    The notes will not be subject to any sinking fund. We may redeem a note at
our option prior to its stated maturity date only if an initial redemption date
is specified for the note, in which case we may redeem the note in whole or from
time to time in part on any date on or after the specified initial redemption
date at the redemption price referred to below together with interest payable to
the redemption date. We will notify the holder of any note to be redeemed not
more than 60 nor less than 30 days before the redemption date. If we redeem a
note, we will do so in increments of $1,000, provided that any remaining
principal amount will be an authorized denomination of the note. Unless
otherwise specified, the redemption price will initially be a specified
percentage of the principal amount to be redeemed and will decline by a
specified percentage at each anniversary of the initial redemption date until
the redemption price is 100% of the principal amount to be redeemed. If we
redeem notes in book-entry form, we will send the notice of redemption to the
depositary. If less than all of the notes in book-entry form of like tenor and
terms are being redeemed, DTC's practice is to determine by lot the amount of
the interest of each participating member of DTC in the issue to be redeemed.

REPAYMENT AT THE OPTION OF THE HOLDER

    We will repay a note before its stated maturity date at the option of the
holder of the note only if an optional repayment date is specified for the note,
in which case, at the option of the holder we will repay the note in whole or in
part on the specified repayment date. Any repayment in part will be in

                                      S-7
<Page>
an amount equal to $1,000 or an integral multiple of $1,000, provided that any
remaining principal amount will be an authorized denomination of the note. The
price for any note so repaid will be 100% of the principal amount to be repaid,
together with interest payable to the date of repayment. For any note to be
repaid, the trustee must receive, at its office maintained for such purpose in
the Borough of Manhattan, The City of New York, currently its corporate trust
office, not more than 60 nor less than 30 days before the optional repayment
date, notice of the holder's exercise of the repayment option, consisting of:

    - in the case of a note in certificated form, the note and the form entitled
      "Option to Elect Repayment" duly completed, or

    - in the case of a note in book-entry form, instructions to that effect from
      the beneficial owner to the depositary and forwarded by the depositary.

Notice of a holder's exercise of the repayment option must be received by the
trustee by 5:00 P.M., New York City time, on the last day for giving notice.
Exercise of the repayment option by the holder of a note will be irrevocable.

    Only the depositary may exercise the repayment option in respect of global
securities representing notes in book-entry form. Accordingly, beneficial owners
of global securities that desire to have all or any portion of the notes in
book-entry form represented by global securities repaid must instruct the
participant through which they own their interest to direct the depositary to
exercise the repayment option on their behalf by forwarding the repayment
instructions to the trustee as discussed above. In order to ensure that the
instructions are received by the trustee on a particular day, the applicable
beneficial owner must so instruct the participant through which it owns its
interest before that participant's deadline for accepting instructions for that
day. Different firms may have different deadlines for accepting instructions
from their customers. Accordingly, beneficial owners of notes in book-entry form
should consult the participants through which they own their interest for the
respective deadlines. All instructions given to participants from beneficial
owners of notes in book-entry form relating to the option to elect repayment
will be irrevocable. In addition, at the time instructions are given, each
beneficial owner will cause the participant through which it owns its interest
to transfer its interest in the global security or securities representing the
related notes in book-entry form, on the depositary's records, to the trustee.
See "--Book-Entry Notes".

    If applicable, we will comply with the requirements of Section 14(e) of the
Securities Exchange Act of 1934, as amended, and the rules promulgated
thereunder and any other securities laws or regulations in connection with any
repayment at the option of the holder.

    We may at any time purchase notes at any price or prices in the open market
or otherwise. Notes so purchased may, at our discretion, be held, resold or
surrendered to the trustee for cancellation.

INTEREST

    Each interest-bearing note will bear interest from and including the date of
issue at the specified annual rate or, in the case of a floating rate note,
pursuant to the specified interest rate formula, until the principal of the note
is paid or made available for payment. Interest will be payable in arrears on
each interest payment date and at Maturity. The first payment of interest on any
note originally issued between a regular record date and the related interest
payment date will be made on the interest payment date immediately following the
next succeeding regular record date to the registered holder on the next
succeeding regular record date. The regular record date will be the fifteenth
calendar day, whether or not a Business Day, immediately preceding the related
interest payment date.

                                      S-8
<Page>
    FIXED RATE NOTES

    Each fixed rate note will bear interest from and including the date of issue
at the rate stated on the face of the note until the principal amount of the
note is paid or made available for payment. Interest payments on fixed rate
notes will equal the amount of interest accrued from and including the
immediately preceding interest payment date in respect of which interest has
been paid, or from and including the date of issue if no interest has been paid,
with respect to the notes to, but excluding, the related interest payment date
or Maturity, as the case may be. Interest on fixed rate notes will be computed
on the basis of a 360-day year consisting of twelve 30-day months.

    Unless otherwise provided in an applicable pricing supplement, interest on
fixed rate notes will be payable semiannually on March 1 and September 1 of each
year and at Maturity. If any interest payment date or the Maturity of a fixed
rate note falls on a day that is not a Business Day (as defined below), the
related payment of principal, premium, if any, or interest will be made on the
next succeeding Business Day as if made on the date the payment was due, and no
interest will accrue on the amount payable for the period from and after the
interest payment date or Maturity, as the case may be.

    For purposes of fixed rate notes, "Business Day" means each Monday, Tuesday,
Wednesday, Thursday and Friday that is not a day on which banking institutions
in The City of New York are authorized or obligated by law or executive order to
close.

    FLOATING RATE NOTES

    Interest on floating rate notes will be determined by reference to the
applicable interest rate basis or interest rate bases, which may be one or more
of:

    - the CD Rate,

    - the CMT Rate,

    - the Commercial Paper Rate,

    - the Eleventh District Cost of Funds Rate,

    - the Federal Funds Rate,

    - LIBOR,

    - the Prime Rate,

    - the Treasury Rate, or

    - any other specified interest rate basis or interest rate formula.

    Each interest rate basis will be the rate determined by the calculation
agent in accordance with the applicable provisions below. The interest rate in
effect on a floating rate note for the period from and including the date of
issue to but excluding the first Interest Reset Date (as defined below) will be
the rate specified in the applicable pricing supplement (the "Initial Interest
Rate"). Thereafter, the interest rate in effect on each day will be (1) if the
day is an Interest Reset Date, the interest rate determined as of the Interest
Determination Date (as defined below) immediately preceding such Interest Reset
Date, or (2) if the day is not an Interest Reset Date, the interest rate
determined as of the Interest Determination Date immediately preceding the most
recent Interest Reset Date. Interest rate changes will take effect on the
Interest Reset Dates.

                                      S-9

    INTEREST TERMS.  Each applicable pricing supplement will specify certain
terms of the floating rate note being delivered, including:

    - whether the floating rate note is

       - a "Regular Floating Rate Note",

       - an "Inverse Floating Rate Note" or

       - a "Floating Rate/Fixed Rate Note" and, if so, the Fixed Rate
         Commencement Date (as defined below) and the Fixed Interest Rate (as
         defined below),

    - the interest rate basis or bases,

    - the Interest Reset Dates,

    - the Initial Interest Rate,

    - the interest payment dates,

    - the period to maturity of the instrument or obligation with respect to
      which the interest rate basis or bases will be calculated (the "Index
      Maturity"),

    - the Maximum Interest Rate (as defined below) and Minimum Interest Rate (as
      defined below), if any,

    - the number of basis points to be added to or subtracted from the related
      interest rate basis or bases (the "Spread"),

    - the percentage by which the interest rate basis or bases will be
      multiplied to determine the applicable interest rate (the "Spread
      Multiplier"),

    - if one of the specified interest rate bases is LIBOR, the Designated LIBOR
      Page (as defined below), and

    - if one of the specified interest rate bases is the CMT Rate, the specified
      CMT Telerate Page and, if CMT Telerate Page 7052, the specified average
      yield period.

    The interest rate borne by the floating rate notes will be determined as
follows:

    REGULAR FLOATING RATE NOTES.  Unless a floating rate note is designated as a
Floating Rate/Fixed Rate Note, an Inverse Floating Rate Note or as having an
Addendum attached or as having "Other Provisions" apply relating to a different
interest rate formula, it will be a "Regular Floating Rate Note" and, except as
described below or in an applicable pricing supplement, will bear interest at
the rate determined by reference to the applicable interest rate basis or bases:

    - plus or minus the applicable Spread, if any, and/or

    - multiplied by the applicable Spread Multiplier, if any.

Commencing on the first Interest Reset Date, the rate at which interest on a
Regular Floating Rate Note will be payable will be reset as of each Interest
Reset Date; provided, however, that the interest rate in effect for the period
from the date of issue to the first Interest Reset Date will be the Initial
Interest Rate.

    FLOATING RATE/FIXED RATE NOTES.  If a floating rate note is designated as a
"Floating Rate/Fixed Rate Note", except as described below or in an applicable
pricing supplement, it will bear interest at the rate determined by reference to
the applicable interest rate basis or bases:

    - plus or minus the applicable Spread, if any, and/or

    - multiplied by the applicable Spread Multiplier, if any.

                                      S-10
<Page>
Commencing on the first Interest Reset Date, the rate at which interest on the
Floating Rate/Fixed Rate Note will be payable will be reset as of each Interest
Reset Date; provided, however, that:

    - the interest rate in effect for the period from the date of issue to the
      first Interest Reset Date will be the Initial Interest Rate, and

    - the interest rate in effect commencing on, and including, the date on
      which interest begins to accrue on a fixed rate basis (the "Fixed Rate
      Commencement Date") will be the specified interest rate (the "Fixed
      Interest Rate") or, if no Fixed Interest Rate is specified, the interest
      rate in effect on the Floating Rate/Fixed Rate Note on the day immediately
      preceding the Fixed Rate Commencement Date, and such interest rate will
      continue in effect until Maturity of the note.

    INVERSE FLOATING RATE NOTES.  If a floating rate note is designated as an
"Inverse Floating Rate Note", except as described below or in an applicable
pricing supplement, it will bear interest at the rate equal to the specified
fixed interest rate minus the rate determined by reference to the applicable
interest rate basis or bases:

    - plus or minus the applicable Spread, if any, and/or

    - multiplied by the applicable Spread Multiplier, if any;

provided, however, that unless otherwise specified, the interest rate on the
Inverse Floating Rate Note will not be less than zero percent. Commencing on the
first Interest Reset Date, the rate at which interest on the Inverse Floating
Rate Note will be payable will be reset as of each Interest Reset Date;
provided, however, that the interest rate in effect for the period from the date
of issue to the first Interest Reset Date will be the Initial Interest Rate.

    INTEREST RESET DATES.  The applicable pricing supplement will specify the
dates on which the interest rate on the applicable floating rate note will be
reset (each, an "Interest Reset Date"). The Interest Reset Date will be, in the
case of floating rate notes which reset:

    - daily--each Business Day;

    - weekly--the Wednesday of each week, with the exception of weekly reset
      floating rate notes as to which the Treasury Rate is an applicable
      interest rate basis, which will reset the Tuesday of each week, except as
      described below;

    - monthly--the third Wednesday of each month, with the exception of monthly
      reset floating rate notes as to which the Eleventh District Cost of Funds
      Rate is an applicable interest rate basis, which will reset on the first
      calendar day of the month;

    - quarterly--the third Wednesday of March, June, September and December of
      each year;

    - semiannually--the third Wednesday of the two specified months of each
      year; and

    - annually--the third Wednesday of the specified month of each year;

provided, however, that with respect to Floating Rate/Fixed Rate Notes, the
interest rate will no longer reset after the Fixed Rate Commencement Date.

    If any Interest Reset Date falls on a day that is not a Business Day, it
will be postponed to the next Business Day, except that in the case of a
floating rate note as to which LIBOR is an applicable interest rate basis, if
that Business Day falls in the next calendar month, then the Interest Reset Date
will be advanced to the immediately preceding Business Day. In addition, in the
case of a floating rate note for which the Treasury Rate is an applicable
interest rate basis, if the Interest Determination Date falls on an Interest
Reset Date, then the Interest Reset Date will be postponed to the next Business
Day.

                                      S-11
<Page>
    MAXIMUM AND MINIMUM INTEREST RATES.  A floating rate note may also have
either or both of the following:

    - a maximum numerical limitation, or ceiling, on the rate at which interest
      may accrue during any period (a "Maximum Interest Rate"), and

    - a minimum numerical limitation, or floor, on the rate at which interest
      may accrue during any period (a "Minimum Interest Rate").

    In addition to any Maximum Interest Rate that may apply to a floating rate
note, the interest rate on floating rate notes will in no event be higher than
the maximum rate permitted by New York law, as the same may be modified by
United States law of general application.

    INTEREST PAYMENTS.  Each applicable pricing supplement will specify the
dates on which interest will be payable. Each floating rate note will bear
interest from and including the date of issue until the principal of the note is
paid or made available for payment. Except as provided below or in the
applicable pricing supplement, the interest payment dates with respect to
floating rate notes will be, in the case of floating rate notes which reset:

    - daily, weekly or monthly--the third Wednesday of each month or the third
      Wednesday of March, June, September and December of each year, as
      specified;

    - quarterly--the third Wednesday of March, June, September and December of
      each year;

    - semiannually--the third Wednesday of the two specified months of each
      year;

    - annually--the third Wednesday of the specified month of each year; and

    - at Maturity.

    If any interest payment date for any floating rate note, other than an
interest payment date at Maturity, falls on a day that is not a Business Day,
the interest payment date will be postponed to the next Business Day, except
that, in the case of a floating rate note as to which LIBOR is an applicable
interest rate basis, if that Business Day falls in the next calendar month, then
the interest payment date will be advanced to the immediately preceding Business
Day. If the Maturity of a floating rate note falls on a day that is not a
Business Day, the payment of principal, premium, if any, and interest will be
made on the next Business Day, and no interest on such payment will accrue for
the period from and after the Maturity.

    For purposes of floating rate notes, "Business Day" means each Monday,
Tuesday, Wednesday, Thursday and Friday that is not a day on which banking
institutions in The City of New York are authorized or obligated by law or
executive order to close; provided, however, that, with respect to notes as to
which LIBOR is an applicable interest rate basis, the day must also be a London
Business Day. "London Business Day" means a day on which commercial banks are
open for business in London.

    All percentages resulting from any calculation on floating rate notes will
be rounded to the nearest one hundred-thousandth of a percentage point, with
five one-millionths of a percentage point rounded upward. For example,
5.876545%, or .05876545, would be rounded to 5.87655%, or .0587655. All dollar
amounts used in or resulting from any calculation on floating rate notes will be
rounded to the nearest cent, with one-half cent being rounded upward.

    Interest payments on floating rate notes will equal the amount of interest
accrued from and including the immediately preceding interest payment date in
respect of which interest has been paid, or from and including the date of issue
if no interest has been paid, to but excluding the related interest payment date
or Maturity.

                                      S-12
<Page>
    With respect to each floating rate note, accrued interest is calculated by
multiplying its face amount by an accrued interest factor. The accrued interest
factor is computed by adding the interest factor calculated for each day in the
period for which accrued interest is being calculated.

    - In the case of notes for which the interest rate basis is the CD Rate, the
      Commercial Paper Rate, the Eleventh District Cost of Funds Rate, the
      Federal Funds Rate, LIBOR or the Prime Rate, the interest factor for each
      day will be computed by dividing the interest rate applicable to each day
      by 360.

    - In the case of notes for which the interest rate basis is the CMT Rate or
      the Treasury Rate, the interest factor for each day will be computed by
      dividing the interest rate applicable to each day by the actual number of
      days in the year.

    - The interest factor for notes for which the interest rate is calculated
      with reference to two or more interest rate bases will be calculated in
      each period in the same manner as if only one of the applicable interest
      rate bases applied.

    INTEREST DETERMINATION DATES.  The interest rate applicable to each interest
period commencing on the Interest Reset Date with respect to that interest
period will be determined by reference to the applicable interest rate basis as
of the applicable "Interest Determination Date", which will be:

    - with respect to the Federal Funds Rate and the Prime Rate--the Business
      Day preceding the related Interest Reset Date;

    - with respect to the CD Rate, the CMT Rate and the Commercial Paper
      Rate--the second Business Day preceding the related Interest Reset Date;

    - with respect to the Eleventh District Cost of Funds Rate--the last working
      day of the month preceding the month in which the related Interest Reset
      Date falls on which the Federal Home Loan Bank of San Francisco publishes
      the Index, as defined below;

    - with respect to LIBOR--the second London Business Day preceding the
      related Interest Reset Date; and

    - with respect to the Treasury Rate--the day in the week in which the
      related Interest Reset Date falls on which direct obligations of the
      United States ("Treasury Bills") are normally auctioned. Treasury Bills
      are normally sold at auction on Monday of each week, unless that day is a
      legal holiday, in which case the auction is normally held on the following
      Tuesday, except that the auction may be held on the preceding Friday;
      provided, however, that if an auction is held on the Friday of the week
      preceding the Interest Reset Date, the related Interest Determination Date
      will be that Friday. If the auction is held on the following Tuesday or
      any other Interest Reset Date, then the Interest Reset Date that otherwise
      would have been on that day will be postponed to the next Business Day. If
      no auction is held for a particular week, the Interest Determination Date
      pertaining to the Interest Reset Date occurring in that week will be the
      first Business Day of that week.

    CALCULATION AGENT AND CALCULATION DATE.  Citibank, N.A. will be the
calculation agent. Upon the request of the holder of any floating rate note, the
calculation agent will provide the interest rate then in effect and, if
determined, the interest rate that will become effective as a result of a
determination made for the next Interest Reset Date with respect to that
floating rate note. The calculation date, if applicable, pertaining to any
Interest Determination Date will be the earlier of:

    - the tenth calendar day after the applicable Interest Determination Date,
      or, if the tenth calendar day is not a Business Day, the next Business Day
      or

    - the Business Day preceding the applicable interest payment date or
      Maturity, as the case may be.

                                      S-13

    CD RATE.  CD Rate Notes will bear interest at rates calculated with
reference to the CD Rate and the specified Spread and/or Spread Multiplier, if
any.

       offered rates for Negotiable CDs (as defined below), as quoted as of
       10:00 A.M., New York City time, on the applicable Interest Determination
       Date by three leading non-bank dealers in negotiable United States dollar
       certificates of deposit in The City of New York (which may include one or
       more of the agents or one or more of their affiliates) selected by the
       calculation agent, or

    (4) if one or more of the dealers selected by the calculation agent are not
       quoting as mentioned in clause (3), the rate in effect on the applicable
       Interest Determination Date.

    "Negotiable CDs" means negotiable United States dollar certificates of
deposit of major United States money center banks with a remaining maturity
closest to the specified Index Maturity and in an amount that is representative
for a single transaction in the market at the time.

OTHER PROVISIONS; ADDENDA

    Any provisions with respect to an issue of notes, including the
specification and determination of one or more interest rate bases, the
calculation of the interest rate applicable to a floating rate note, the
applicable interest payment dates, the stated maturity date, any redemption or
repayment provisions or any other matter relating to the applicable notes may be
modified by the terms as specified under "Other Provisions" on the face of the
applicable notes or in an Addendum relating to the applicable notes, if so
specified on the face of the applicable notes and in the applicable pricing
supplement.

DISCOUNT NOTES

    We may from time to time offer notes ("Discount Notes") that have a
specified issue price that is less than 100% of the principal amount thereof
(i.e. par) by more than a percentage equal to the product of 0.25% and the
number of full years between the date of issue and the regularly scheduled
maturity of the note. Discount Notes may not bear any interest currently or may
bear interest at a rate that is below market rates at the time of issuance. The
difference between the issue price of a Discount Note and par is referred to as
the "Discount". In the event of redemption, repayment or acceleration of
maturity of a Discount Note, the amount payable to the holder will be equal to
the sum of:

    - the issue price (increased by any accruals of Discount) and, in the event
      of redemption, multiplied by a percentage of the principal amount as
      described above under "--Redemption at Our Option"; and

    - any unpaid interest accrued on the Discount Note to the date of the
      redemption, repayment or acceleration of maturity, as the case may be.

                                      S-21
<Page>
    For purposes of determining the amount of Discount that has accrued as of
any date on which a redemption, repayment or acceleration of maturity occurs for
a Discount Note, Discount will be accrued using a constant yield method. The
constant yield will be calculated using a 30-day month, 360-day year convention,
a compounding period that, except for the Initial Period (as defined below),
corresponds to the shortest period between interest payment dates for the
applicable Discount Note (with ratable accruals within a compounding period), a
coupon rate equal to the initial coupon rate applicable to the Discount Note and
an assumption that the maturity of a Discount Note will not be accelerated. If
the period from the date of issue to the first interest payment date for a
Discount Note (the "Initial Period") is shorter than the compounding period for
the Discount Note, a proportionate amount of the yield for an entire compounding
period will be accrued. If the Initial Period is longer than the compounding
period, then the period will be divided into a regular compounding period and a
short period with the short period being treated as provided in the preceding
sentence. The accrual of Discount for the above purposes may differ from the
accrual of original issue discount for Federal income tax purposes. Certain
Discount Notes may not be treated as having original issue discount for Federal
income tax purposes, and notes other than Discount Notes may be treated as
issued with original issue discount for Federal income tax purposes. See
"Certain United States Federal Income Tax Considerations".

INDEXED NOTES

    We may from time to time offer notes ("Indexed Notes") with the amount of
principal, premium and/or interest payable in respect thereof to be determined
with reference to the price or prices, yield or value of one or more specified
commodities or securities, to any statistical measure of economic or financial
performance, including, without limitation, any currency, consumer price or
mortgage index, or to other items, in each case as specified in the applicable
pricing supplement. In certain cases, holders of Indexed Notes may receive a
principal payment at Maturity that is greater than or less than the principal
amount of such Indexed Notes, depending upon the relative value on the date of
Maturity of the specified indexed item. Information as to the method for
determining the amount of principal, premium, if any, and/or interest, if any,
payable in respect of Indexed Notes, certain historical information with respect
to the specified indexed item and any material tax considerations associated
with an investment in Indexed Notes will be specified in the applicable pricing
supplement. See also "Risk Factors".

EXTENDIBLE MATURITY NOTES

    We may from time to time offer notes ("Extendible Maturity Notes") with the
option to extend the maturity of the notes to one or more dates indicated in the
notes and the applicable pricing supplement. The terms of and any additional
considerations relating to any Extendible Maturity Notes will be specified in
the applicable pricing supplement.

AMORTIZING NOTES

    We may from time to time offer notes ("Amortizing Notes") with amounts of
principal and interest payable in installments over the term of the notes.
Interest on Amortizing Notes will be computed on the basis of a 360-day year
consisting of twelve 30-day months. Payments with respect to Amortizing Notes
will be applied first to interest due and payable on the Amortizing Notes and
then to the reduction of the unpaid principal amount of the Amortizing Notes.
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 note and the applicable pricing supplement.

                                      S-22
<Page>
BOOK-ENTRY NOTES

    The notes may be issued, in whole or in part, in book-entry form. Upon
issuance, all notes in book-entry form having the same date of issue, Maturity
and otherwise having identical terms and provisions will be represented by one
or more fully registered global notes. One fully registered global note will be
issued for each issue of notes, each in the aggregate principal amount of the
issue, unless the aggregate principal amount of any issue exceeds $500,000,000,
in which case one global note will be issued with respect to each $500,000,000
of principal amount and an additional global note will be issued with respect to
any remaining principal amount of the issue.

    Each global note will be deposited with, or on behalf of, DTC or any other
specified depositary. The global notes will be issued as fully registered
securities and will be registered in the name of DTC or such other depositary
(or their nominees). See "Description of Debt Securities--Global Debt
Securities" in the accompanying prospectus.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

risks or as a position in a "straddle" for tax purposes, or persons whose
functional currency is not the United States dollar. It also does not deal with
holders other than original purchasers, except where otherwise specifically
noted. Persons considering the purchase of the notes should consult their own
tax advisers concerning the application of United States Federal income tax laws
to their particular situations as well as any consequences of the purchase,
ownership and disposition of the notes arising under the laws of any other
taxing jurisdiction.

    As used in this prospectus supplement, the term "U.S. Holder" means a
beneficial owner of a note that is for United States Federal income tax
purposes:

    (1) a citizen or resident of the United States,

    (2) a corporation or a partnership (including an entity treated as a
       corporation or a partnership for United States Federal income tax
       purposes) created or organized in or under the laws of the United States,
       any state thereof or the District of Columbia (other than a partnership
       that is not treated as a United States person under any applicable
       Treasury regulations),

    (3) an estate whose income is subject to United States Federal income tax
       regardless of its source,

    (4) a trust if a court within the United States is able to exercise primary
       supervision over the administration of the trust and one or more United
       States persons have the authority to control all substantial decisions of
       the trust, or

    (5) any other person whose income or gain in respect of a note is
       effectively connected with the conduct of a United States trade or
       business.

Notwithstanding the preceding clause (4), to the extent provided in regulations,
certain trusts that (1) were in existence on August 20, 1996, (2) prior to that
date, were treated as United States persons under the United States Internal
Revenue Code of 1986, as amended (the "Code"), and applicable Treasury
regulations thereunder, and (3) elect to continue to be so treated, also will be
U.S. Holders for purposes of the following discussion. As used herein, the term
"non-U.S. Holder" means a beneficial owner of a note that is not a U.S. Holder.

U.S. HOLDERS

    PAYMENTS OF INTEREST.  Payments of interest on a note generally will be
taxable to a U.S. Holder as ordinary interest income at the time such payments
are accrued or are received (in accordance with the U.S. Holder's regular method
of tax accounting).

    ORIGINAL ISSUE DISCOUNT.  The following summary is a general discussion of
the United States Federal income tax consequences to U.S. Holders of the
purchase, ownership and disposition of notes issued with original issue discount
within the meaning of the Code ("Original Issue Discount Notes"). The following
summary is based upon final Treasury regulations (the "OID Regulations")
released by the Internal Revenue Service on January 27, 1994, as amended on
June 11, 1996, under the original issue discount provisions of the Code.

    For United States Federal income tax purposes, original issue discount is
the excess of the stated redemption price at maturity of a note over its issue
price if such excess equals or exceeds a DE MINIMIS amount (generally 1/4 of 1%
of the note's stated redemption price at maturity multiplied by the number of
complete years to its maturity from its issue date or, in the case of a note
providing for the payment of any amount other than qualified stated interest (as
defined below) prior to maturity, multiplied by the weighted average maturity of
the note). The issue price of each note of an issue of notes equals the first
price at which a substantial amount of the notes has been sold (ignoring sales
to bond houses, brokers, or similar persons or organizations acting in the
capacity of underwriters, placement agents, or wholesalers). The stated
redemption price at maturity of a note is the sum of all payments provided by
the note other than "qualified stated interest" payments. The term "qualified
stated interest" generally means stated interest that is unconditionally payable
in cash or property (other than debt instruments of the issuer) at least
annually at a single fixed rate. In addition, under the OID Regulations, if a
note bears interest for one or more accrual periods at a rate below the rate
applicable for the remaining term of the note (e.g., notes with teaser rates or
interest holidays), and if the greater of either the resulting foregone interest
on the note or any "true" discount on the note (i.e., the excess of the note's
stated principal amount over its issue price) equals or exceeds a specified DE
MINIMIS amount, then the stated interest on the note would be treated as
original issue discount rather than qualified stated interest.

    Payments of qualified stated interest on a note are taxable to a U.S. Holder
as ordinary interest income at the time such payments are accrued or are
received (in accordance with the U.S. Holder's regular method of tax
accounting). A U.S. Holder of an Original Issue Discount Note must include
original issue discount in income as ordinary interest for United States Federal
income tax purposes as it accrues under a constant yield method in advance of
receipt of the cash payments attributable to such income, regardless of the U.S.
Holder's regular method of tax accounting. In general, the amount of original
issue discount included in income by the initial U.S. Holder of an Original
Issue Discount Note is the sum of the daily portions of original issue discount
with respect to the Original Issue Discount Note for each day during the taxable
year (or portion of the taxable year) on which the U.S. Holder held the Original
Issue Discount Note. The "daily portion" of original issue discount on any
Original Issue Discount Note is determined by allocating to each day in any
accrual period a ratable portion of the original issue discount allocable to
that accrual period. An "accrual period" may be of any length and the accrual
periods may vary in length over the term of the Original Issue Discount Note,
provided that each accrual period is no longer than one year and each scheduled
payment of principal or interest occurs either on the final day of an accrual
period or on the first day of an accrual period. The amount of original issue
discount allocable to each accrual period is generally equal to the difference
between:

    - the product of the Original Issue Discount 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
      appropriately adjusted to take into account the length of the particular
      accrual period), and

                                      S-24
<Page>
    - the amount of any qualified stated interest payments allocable to such
      accrual period.

    The "adjusted issue price" of an Original Issue Discount Note at the
beginning of any accrual period is the sum of the issue price of the Original
Issue Discount Note plus the amount of original issue discount allocable to all
prior accrual periods minus the amount of any prior payments on the Original
Issue Discount Note that were not qualified stated interest payments. Under
these rules, U.S. Holders generally will have to include in income increasingly
greater amounts of original issue discount in successive accrual periods.

    A U.S. Holder who purchases an Original Issue Discount Note for an amount
that is greater than its adjusted issue price as of the purchase date and less
than or equal to the sum of all amounts payable on the Original Issue Discount
Note after the purchase date, other than payments of qualified stated interest,
will be considered to have purchased the Original Issue Discount Note at an
"acquisition premium". Under the acquisition premium rules, the amount of
original issue discount which such U.S. Holder must include in its gross income
with respect to such Original Issue Discount Note for any taxable year (or
portion thereof in which the U.S. Holder holds the Original Issue Discount Note)
will be reduced (but not below zero) by the portion of the excess properly
allocable to the period. If the purchase price exceeds the adjusted issue price
and the sum of amounts payable on the Original Issue Discount Note other than
payments of qualified stated interest, the U.S. Holder will also be entitled to
deductions for amortizable bond premium as discussed below.

    Under the OID Regulations, floating rate notes (hereinafter "Variable
Notes") are subject to special rules whereby a Variable Note will qualify as a
"variable rate debt instrument" if:

    - its issue price does not exceed the total noncontingent principal payments
      due under the Variable Note by more than a specified DE MINIMIS amount,
      and

    - it provides for stated interest, paid or compounded at least annually, at
      current values of:

       - one or more qualified floating rates,

       - a single fixed rate and one or more qualified floating rates,

       - a single objective rate, or

       - a single fixed rate and a single objective rate that is a qualified
         inverse floating rate.

    A "qualified floating rate" is any variable rate where variations in the
value of such rate can reasonably be expected to measure contemporaneous
variations in the cost of newly borrowed funds in the currency in which the
Variable Note is denominated. Although a multiple of a qualified floating rate
will generally not itself constitute a qualified floating rate, a variable rate
equal to the product of a qualified floating rate and a fixed multiple that is
greater than .65 but not more than 1.35 will constitute a qualified floating
rate. A variable rate equal to the product of a qualified floating rate and a
fixed multiple that is greater than .65 but not more than 1.35, increased or
decreased by a fixed rate, will also constitute a qualified floating rate. In
addition, under the OID Regulations, two or more qualified floating rates that
can reasonably be expected to have approximately the same values throughout the
term of the Variable Note (e.g., two or more qualified floating rates with
values within 25 basis points of each other as determined on the Variable Note's
issue date) will be treated as a single qualified floating rate. Notwithstanding
the foregoing, a variable rate that would otherwise constitute a qualified
floating rate but which is subject to one or more restrictions such as a maximum
numerical limitation (i.e., a cap) or a minimum numerical limitation (i.e., a
floor) may, under certain circumstances, fail to be treated as a qualified
floating rate under the OID Regulations unless such cap or floor is fixed
throughout the term of the note. An "objective rate" is a rate that is not
itself a qualified floating rate but which is determined using a single fixed
formula that is based on objective financial or economic information. A rate
will not qualify as an objective rate if it is based on information that is
within the control of the issuer (or a related party) or that is unique to the
circumstances of the issuer (or a related party), such as dividends, profits, or
the value of the issuer's

                                      S-25
<Page>
stock (although a rate does not fail to be an objective rate merely because it
is based on the credit quality of the issuer). A "qualified inverse floating
rate" is any objective rate where such rate is equal to a fixed rate minus a
qualified floating rate, as long as variations in the rate can reasonably be
expected to inversely reflect contemporaneous variations in the qualified
floating rate. The OID Regulations also provide that if a Variable Note provides
for stated interest at a fixed rate for an initial period of one year or less
followed by a variable rate that is either a qualified floating rate or an
objective rate and if the variable rate on the Variable Note's issue date is
intended to approximate the fixed rate (e.g., the value of the variable rate on
the issue date does not differ from the value of the fixed rate by more than 25
basis points), then the fixed rate and the variable rate together will
constitute either a single qualified floating rate or objective rate, as the
case may be.

    If a Variable Note that provides for stated interest at either a single
qualified floating rate or a single objective rate throughout the term thereof
qualifies as a "variable rate debt instrument" under the OID Regulations, and if
the interest on a Variable Note is unconditionally payable in cash or property
(other than debt instruments of the issuer) at least annually, then all stated
interest on the Variable Note will constitute qualified stated interest and will
be taxed accordingly. Thus, a Variable Note that provides for stated interest at
either a single qualified floating rate or a single objective rate throughout
the term thereof and that qualifies as a "variable rate debt instrument" under
the OID Regulations will generally not be treated as having been issued with
original issue discount unless the Variable Note is issued at a "true" discount
(i.e., at a price below the Variable Note's stated principal amount) in excess
of a specified DE MINIMIS amount. The amount of qualified stated interest and
the amount of original issue discount, if any, that accrues during an accrual
period on such a Variable Note is determined under the rules applicable to fixed
rate debt instruments by assuming that the variable rate is a fixed rate equal
to:

    - in the case of a qualified floating rate or qualified inverse floating
      rate, the value, as of the issue date, of the qualified floating rate or
      qualified inverse floating rate, or

    - in the case of an objective rate (other than a qualified inverse floating
      rate), a fixed rate that reflects the yield that is reasonably expected
      for the Variable Note.

The qualified stated interest allocable to an accrual period is increased (or
decreased) if the interest actually paid during an accrual period exceeds (or is
less than) the interest assumed to be paid during the accrual period pursuant to
the foregoing rules.

    In general, any other Variable Note that qualifies as a "variable rate debt
instrument" will be converted into an "equivalent" fixed rate debt instrument
for purposes of determining the amount and accrual of original issue discount
and qualified stated interest on the Variable Note. The OID Regulations
generally require that such a Variable Note be converted into an "equivalent"
fixed rate debt instrument by substituting any qualified floating rate or
qualified inverse floating rate provided for under the terms of the Variable
Note with a fixed rate equal to the value of the qualified floating rate or
qualified inverse floating rate, as the case may be, as of the Variable Note's
issue date. Any objective rate (other than a qualified inverse floating rate)
provided for under the terms of the Variable Note is converted into a fixed rate
that reflects the yield that is reasonably expected for the Variable Note. In
the case of a Variable Note that qualifies as a "variable rate debt instrument"
and provides for stated interest at a fixed rate in addition to either one or
more qualified floating rates or a qualified inverse floating rate, the fixed
rate is initially converted into a qualified floating rate (or a qualified
inverse floating rate, if the Variable Note provides for a qualified inverse
floating rate). Under such circumstances, the qualified floating rate or
qualified inverse floating rate that replaces the fixed rate must be such that
the fair market value of the Variable Note as of the Variable Note's issue date
is approximately the same as the fair market value of an otherwise identical
debt instrument that provides for either the qualified floating rate or
qualified inverse floating rate rather than the fixed rate. Subsequent to
converting the fixed rate into either a qualified floating rate or a qualified
inverse

                                      S-26
<Page>
floating rate, the Variable Note is then converted into an "equivalent" fixed
rate debt instrument in the manner described above.

    Once the Variable Note is converted into an "equivalent" fixed rate debt
instrument pursuant to the foregoing rules, the amount of original issue
discount and qualified stated interest, if any, are determined for the
"equivalent" fixed rate debt instrument by applying the general original issue
discount rules to the "equivalent" fixed rate debt instrument and a U.S. Holder
of the Variable Note will account for such original issue discount and qualified
stated interest as if the U.S. Holder held the "equivalent" fixed rate debt
instrument. In each accrual period, appropriate adjustments will be made to the
amount of qualified stated interest or original issue discount assumed to have
been accrued or paid with respect to the "equivalent" fixed rate debt instrument
in the event that such amounts differ from the actual amount of interest accrued
or paid on the Variable Note during the accrual period.

    If a Variable Note does not qualify as a "variable rate debt instrument"
under the OID Regulations, then the Variable Note would be treated as a
contingent payment debt obligation. On June 11, 1996, the Treasury Department
issued final regulations (the "CPDI Regulations") concerning the proper United
States Federal income tax treatment of contingent payment debt instruments. In
general, the CPDI Regulations would cause the timing and character of income,
gain or loss reported on a contingent payment debt instrument to substantially
differ from the timing and character of income, gain or loss reported on a
contingent payment debt instrument under general principles of current United
States Federal income tax law. Specifically, the CPDI Regulations generally
require a U.S. Holder of such an instrument to include future contingent and
noncontingent interest payments in income as such interest accrues based upon a
projected payment schedule. Moreover, in general, under the CPDI Regulations,
any gain recognized by a U.S. Holder on the sale, exchange, or retirement of a
contingent payment debt instrument will be treated as ordinary income and all or
a portion of any loss realized could be treated as ordinary loss as opposed to
capital loss (depending upon the circumstances). The CPDI Regulations apply to
debt instruments issued on or after August 13, 1996. The proper United States
Federal income tax treatment of Variable Notes that are treated as contingent
payment debt obligations will be more fully described in the applicable pricing
supplement. Furthermore, any other special United States Federal income tax
considerations, not otherwise discussed herein, which are applicable to any
particular issue of notes will be discussed in the applicable pricing
supplement.

    We may issue notes which:

    - may be redeemable at our option prior to their stated maturity (a "call
      option") and/or

    - may be repayable at the option of the holder prior to their stated
      maturity (a "put option").

Notes containing such features may be subject to rules that differ from the
general rules discussed above. Investors intending to purchase notes with such
features should consult their own tax advisors, since the original issue
discount consequences will depend, in part, on the particular terms and features
of the purchased notes.

    U.S. Holders may generally, upon election, include in income all interest
(including stated interest, acquisition discount, original issue discount, DE
MINIMIS original issue discount, market discount, DE MINIMIS market discount,
and unstated interest, as adjusted by any amortizable bond premium or
acquisition premium) that accrues on a debt instrument by using the constant
yield method applicable to original issue discount, subject to certain
limitations and exceptions.

                                      S-27
<Page>
    SHORT-TERM NOTES.  Notes that have a fixed maturity of one year or less
("Short-Term Notes") will be treated as having been issued with original issue
discount. In general, an individual or other cash method U.S. Holder is not
required to accrue such original issue discount unless the U.S. Holder elects to
do so. If such an election is not made, any gain recognized by the U.S. Holder
on the sale, exchange or maturity of the Short-Term Note will be ordinary income
to the extent of the original issue discount accrued on a straight-line basis,
or upon election under the constant yield method (based on daily compounding),
through the date of sale or maturity, and a portion of the deductions otherwise
allowable to the U.S. Holder for interest on borrowings allocable to the
Short-Term Note will be deferred until a corresponding amount of income is
realized. U.S. Holders who report income for United States Federal income tax
purposes under the accrual method, and certain other holders including banks and
dealers in securities, are required to accrue original issue discount on a
Short-Term Note on a straight-line basis unless an election is made to accrue
the original issue discount under a constant yield method (based on daily
compounding).

    MARKET DISCOUNT.  If a U.S. Holder purchases a note, other than an Original
Issue Discount Note, for an amount that is less than its issue price (or, in the
case of a subsequent purchaser, its stated redemption price at maturity) or, in
the case of an Original Issue Discount Note, for an amount that is less than its
adjusted issue price as of the purchase date, such U.S. Holder will be treated
as having purchased the note at a "market discount", unless such market discount
is less than a specified DE MINIMIS amount.

    Under the market discount rules, a U.S. Holder will be required to treat any
partial principal payment (or, in the case of an Original Issue Discount Note,
any payment that does not constitute qualified stated interest) on, or any gain
realized on the sale, exchange, retirement or other disposition of, a note as
ordinary income to the extent of the lesser of:

    - the amount of such payment or realized gain, or

    - the market discount which has not previously been included in income and
      is treated as having accrued on the note at the time of such payment or
      disposition.

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 U.S. Holder
elects to accrue market discount on the basis of semiannual compounding.

    A U.S. Holder may be required to defer the deduction of all or a portion of
the interest paid or accrued on any indebtedness incurred or maintained to
purchase or carry a note with market discount until the maturity of the Note or
certain earlier dispositions because a current deduction is only allowed to the
extent the interest expense exceeds an allocable portion of market discount. A
U.S. Holder may elect to include market discount in income currently as it
accrues (on either a ratable or semiannual compounding basis), in which case the
rules described above regarding the treatment as ordinary income of gain upon
the disposition of the note and upon the receipt of certain cash payments and
regarding the deferral of interest deductions will not apply. Generally, such
currently included market discount is treated as ordinary interest for United
States Federal income tax purposes. Such an election will apply to all debt
instruments acquired by the U.S. Holder on or after the first day of the first
taxable year to which such election applies and may be revoked only with the
consent of the IRS.

    PREMIUM.  If a U.S. Holder purchases a note for an amount that is greater
than the sum of all amounts payable on the note after the purchase date other
than payments of qualified stated interest, the U.S. Holder will be considered
to have purchased the note with "amortizable bond premium" equal in amount to
such excess. A U.S. Holder may elect to amortize such premium using a constant
yield method over the remaining term of the note and may offset interest
otherwise required to be included in respect of the note during any taxable year
by the amortized amount of such excess for the taxable year. However, if the
note may be optionally redeemed after the U.S. Holder acquires it at a price in

                                      S-28
<Page>
excess of its stated redemption price at maturity, special rules would apply
which could result in a deferral of the amortization of some bond premium until
later in the term of the note. Any election to amortize bond premium applies to
all taxable debt instruments held by the U.S. Holder on or after the first day
of the first taxable year to which the election applies and may be revoked only
with the consent of the IRS.

    DISPOSITION OF A NOTE.  Except as discussed above, upon the sale, exchange
or retirement of a note, a U.S. Holder generally will recognize taxable gain or
loss equal to the difference between the amount realized on the sale, exchange
or retirement (other than amounts representing accrued and unpaid interest) and
the U.S. Holder's adjusted tax basis in the note. A U.S. Holder's adjusted tax
basis in a note generally will equal the U.S. Holder's initial investment in the
note increased by any original issue discount included in income (and accrued
market discount, if any, if the U.S. Holder has included such market discount in
income) and decreased by the amount of any payments, other than qualified stated
interest payments, received and amortizable bond premium taken with respect to
the note. Such gain or loss generally will be long-term capital gain or loss if
the note were held for more than one year. Non-corporate taxpayers are subject
to reduced maximum rates on long-term capital gains and are generally subject to
ordinary income rates on short-term capital gains. The deductibility of capital
losses is subject to certain limitations. Prospective investors should consult
their own tax advisors concerning these tax law provisions.

NON-U.S. HOLDERS

    A non-U.S. Holder will not be subject to United States Federal income taxes
on payments of principal, premium (if any) or interest (including original issue
discount, if any) on a note, unless such non-U.S. Holder is a direct or indirect
10% or greater shareholder of AGFC, a controlled foreign corporation related to
AGFC or a bank receiving interest described in section 881(c)(3)(A) of the Code.
To qualify for the exemption from taxation, the Withholding Agent (as defined
below) must have received a statement that (1) is signed by the beneficial owner
of the note under penalties of perjury, (2) certifies that such owner is not a
U.S. Holder and (3) provides the name and address of the beneficial owner. A
"Withholding Agent" is generally the last United States payor (or non-U.S. payor
who is a foreign intermediary, U.S. branch of a foreign person, or withholding
foreign partnership) in the chain of payment prior to payment to a non-U.S.
Holder (which itself is not a Withholding Agent). The statement may be made on
an IRS Form W-8BEN or a substantially similar form, and the beneficial owner
must inform the Withholding Agent of any change in the information on a new
W-8BEN within 30 days of such change. If a note is held through a securities
clearing organization or certain other financial institutions, the organization
or institution may provide a signed statement to the Withholding Agent. However,
in such case, the signed statement must be accompanied by a copy of the IRS
Form W-8BEN or the substitute form provided by the beneficial owner to the
organization or institution.

    The Treasury has issued new regulations (the "New Regulations") effective
for payments made after December 31, 2000 which make certain modifications to
the withholding, backup withholding and information reporting rules. A
Noteholder who is not an individual or corporation (or an entity treated as a
corporation for United States Federal income tax purposes) holding the notes on
its own behalf may have substantially increased reporting requirements. In
particular, in the case of notes held by a foreign partnership (or foreign
trust), the partners (or beneficiaries) rather than the partnership (or trust)
will be required to provide the certification discussed above, and the
partnership (or trust) will be required to provide certain additional
information.

    Generally, a non-U.S. Holder will not be subject to United States Federal
income taxes on any amount which constitutes capital gain upon retirement or
disposition of a note, provided the gain is not effectively connected with the
conduct of a trade or business in the United States by the non-U.S.

                                      S-29
<Page>
Holder. Certain other exceptions may be applicable, and a non-U.S. Holder should
consult its tax advisor in this regard.

    The notes will not be includible in the estate of a non-U.S. Holder unless
the individual is a direct or indirect 10% or greater shareholder of AGFC or, at
the time of such individual's death, payments in respect of the notes would have
been effectively connected with the conduct by such individual of a trade or
business in the United States.

BACKUP WITHHOLDING

    Backup withholding of United States Federal income tax at a rate of 30.5%
(which will be periodically decreased through 2006) may apply to payments made
in respect of the notes to registered owners who are not "exempt recipients" and
who fail to provide certain identifying information, such as the registered
owner's taxpayer identification number, in the required manner.

    Generally, individuals are not exempt recipients, whereas corporations and
certain other entities generally are exempt recipients. Payments made in respect
of the notes to a U.S. Holder must be reported to the IRS, unless the U.S.
Holder is an exempt recipient or establishes an exemption. Compliance with the
identification procedures described in the preceding section would establish an
exemption from backup withholding for those non-U.S. Holders who are not exempt
recipients.

    In addition, upon the sale of a note to (or through) a broker, the broker
must withhold 30.5% (which will be periodically decreased through 2006) of the
entire purchase price, unless either:

    - the broker determines that the seller is a corporation or other exempt
      recipient, or

    - the seller provides, in the required manner, certain identifying
      information and, in the case of a non-U.S. Holder, certifies that such
      seller is a non-U.S. Holder (and certain other conditions are met).

    Such a sale must also be reported by the broker to the IRS, unless either:

    - the broker determines that the seller is an exempt recipient, or

    - the seller certifies its non-U.S. status (and certain other conditions are
      met).

Certification of the registered owner's non-U.S. status would be made normally
on an IRS Form W-8BEN under penalties of perjury, although in certain cases it
may be possible to submit other documentary evidence. In addition, prospective
U.S. Holders are strongly urged to consult their own tax advisors with respect
to the New Regulations. See "--Non-U.S. Holders".

    Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against such
beneficial owner's United States Federal income tax provided the required
information is furnished to the IRS.

agent at a discount to be agreed upon at the time of sale. If agreed to by us
and an agent, the agent may utilize its reasonable efforts on an agency basis on
our behalf to solicit offers to purchase notes at 100% of the principal amount
of the notes. We will pay to each of the agents through which we sell a note on
an agency basis a commission not to exceed .875% of the principal amount of the
note. Certain of the above underwriting and agency arrangements may be changed
with respect to specific notes. We will describe any such change in the
applicable pricing supplement.

    Each agent may sell notes it has purchased from us as principal to certain
dealers at a price equal to the agent's purchase price less a concession in the
amount of all or any portion of the discount received in connection with that
purchase. An agent may allow, and any such dealer may reallow, a discount to
certain other dealers. After the initial public offering of notes, the public
offering price, in the case of notes to be resold at a fixed public offering
price, the concession and the reallowance may be changed.

    We have reserved the right to sell the notes through one or more other
agents or to other persons as principal. If we do so, we will specify the names
of the other agents or principals in the applicable pricing supplement. We also
have reserved the right to sell notes directly to investors without the
assistance of any agent. We will not pay any commission with respect to any
notes we sell directly.

    We reserve the right to withdraw, cancel or modify the offer made by this
prospectus supplement without notice and may reject orders, in whole or in part,
whether placed directly with us or through an agent. 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 it on an agency basis.

    Unless otherwise specified in an applicable pricing supplement, you will be
required to pay the purchase price of your notes in immediately available funds
in U.S. dollars in New York City on the date of settlement.

    No note will have an established trading market when issued. Unless
specified in the applicable pricing supplement, we will not list the notes on
any securities exchange. The agents may from time to time purchase and sell
notes in the secondary market, but they are not obligated to do so, and 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, one or
more of the agents may make a market in the notes, but they are not obligated to
do so and may discontinue any market-making activity at any time.

    The agents may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933, as amended. We have agreed to indemnify the agents
against certain civil liabilities, including liabilities under the Securities
Act, or to contribute to payments the agents may be required to make in respect
thereof. We have agreed to reimburse the agents for certain expenses. We may
make similar arrangements with any other principals or agents to or through
which we sell notes.

    From time to time, each of the agents or their respective affiliates have
engaged and may engage in transactions with and/or perform services, including
investment banking or general financing and banking services, for us and our
affiliates in the ordinary course of business. Ellen V. Futter, a director of
AIG, is also a director of J.P. Morgan Chase & Co., which is an affiliate of
J.P. Morgan Securities Inc.

    From time to time, we may issue and sell other debt securities described in
the accompanying prospectus, and the amount of notes that we may offer and sell
under this prospectus supplement would be reduced as a result of such sales.

    In connection with an offering of notes purchased by one or more of the
agents as principal on a fixed price basis, the applicable agents will be
permitted to engage in certain transactions that stabilize the price of the
notes. These transactions may consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the notes. If those agents create a
short position in notes in connection with the offering, i.e., if they sell
notes in an aggregate principal amount exceeding that set forth in the
applicable pricing supplement, then they 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 short position could have the effect of
raising or maintaining the market price of the security or preventing or
retarding a decline in the market price of the security.

    Neither we nor any agent makes any representation or prediction as to the
direction or magnitude of any effect that the transactions described in the
immediately preceding paragraph may have on the price of notes. In addition,
neither we nor any agent makes any representation that the agents will engage in
any such transactions or that such transactions, once commenced, will not be
discontinued without notice.

                                 LEGAL OPINIONS

    Timothy M. Hayes, our General Counsel, will pass upon the legality of the
notes for us and Baker & Daniels, Indianapolis, Indiana, will pass upon certain
tax matters relating to the notes. Sidley Austin Brown & Wood LLP, New York, New
York, will pass upon certain legal matters relating to the notes for the agents.
Sidley Austin Brown & Wood LLP may rely as to matters of Indiana law on the
opinion of Mr. Hayes. Mr. Hayes owns shares of common stock of AIG and has
options to purchase additional shares of such stock.
