                                     SUMMARY

This summary highlights the important terms of the Notes, which we describe in
greater detail in this prospectus supplement and the prospectus. You should read
this prospectus supplement and the prospectus in their entirety, as well as the
related pricing supplement, before you decide to buy any Notes.

We will provide the specific terms of each issuance of Notes in a pricing
supplement that we will deliver, along with this prospectus supplement and the
prospectus, to prospective buyers of those Notes.

Citicorp expects that the terms described in this prospectus supplement and the
prospectus will apply to most of the Notes that Citicorp issues. However, we may
issue Notes with terms other than or that conflict with the terms in this
prospectus supplement or the prospectus. We will describe those terms in the
pricing supplement that we deliver when we offer those Notes for sale.

You should rely on information in the pricing supplement if it conflicts with
information in this prospectus supplement and the prospectus and you should rely
on information in this prospectus supplement if it conflicts with information in
the prospectus.

THE NOTES

Citicorp may issue at various times up to $3,250,000,000 of its medium-term
Senior Notes, Series F and medium-term Subordinated Notes, Series F. We may also
issue senior and subordinated medium-term notes of other series as well as other
senior and subordinated indebtedness while the Notes are outstanding.

The Senior Notes will be unsecured and will rank equally with all other
unsecured and unsubordinated indebtedness of Citicorp. The Subordinated Notes
will also be unsecured and will rank equally with all other unsecured and
subordinated indebtedness of Citicorp, except that the Subordinated Notes will
rank above any subordinated indebtedness that we designate, at issuance, as
junior to the Subordinated Notes. The Senior Notes will rank above all
subordinated notes in right of payment.

The pricing supplement for each issuance of Notes will state:

o     whether the Notes are Senior Notes or Subordinated Notes;

o     the maturity of the Notes, which will be between 9 months and 60 years
      from the date we issue them;

o     the price at which we are offering the Notes;

o     the currency in which the Notes are denominated if not U.S. dollars;

o     whether the Notes will:

      1.    pay interest at a fixed rate, which we will pay semi-annually;

      2.    pay interest at a floating rate, which we will pay monthly,
            quarterly, semi-annually or annually, as indicated in the pricing
            supplement, and the particular rate or index upon which that
            floating rate will be based; or

      3.    be an indexed Note, an original issue discount Note or a zero coupon
            Note (on which we will not pay interest);

o     the date on which interest will begin to accrue on the Notes, the dates on
      which we will pay interest on the Notes, and the record dates for the
      payment of interest and the repayment of the principal amount of the
      Notes; and


                                      S-3
<PAGE>

o     the redemption and repurchase rights, if any, that we or the holders of
      the Notes will have.

Each Note that we issue will have a minimum denomination of $50,000. Notes
issued in a foreign or composite currency may have a different minimum
denomination. We will pay interest and principal on each Note in the currency of
that Note. We will pay interest and principal on Notes issued in U.S. dollars in
immediately available funds at the office in New York City that Citibank, acting
as paying agent for those Notes, designates. You may register a transfer of or
exchange your U.S. dollar-denominated Note at that office.

The trustee under the indenture that governs the Senior Notes will be United
States Trust Company of New York. The trustee under the indenture that governs
the Subordinated Notes will be The Chase Manhattan Bank.

PLAN OF DISTRIBUTION

The Notes may be offered for sale through Salomon Smith Barney Inc. and may also
be offered through other securities firms acting as agent or principal or
directly by Citicorp. The pricing supplement for each issue of Notes will
indicate:

o     how those Notes will be distributed;

o     the agents or underwriters for the Notes;

o     the selling agent fees or underwriter's commission to be paid by Citicorp;
      and

o     any additional terms that we do not describe or that apply instead of
      those terms described in this prospectus supplement or the prospectus.

<PAGE>

                              DESCRIPTION OF NOTES

      This prospectus supplement describes additional terms and provisions of
the Notes that we describe generally under "Description of Notes" on page 3 of
the prospectus. These descriptions apply to each issuance of the Notes unless we
indicate otherwise in the pricing supplement.

      We will offer our medium-term Senior Notes, Series F and medium-term
Subordinated Notes, Series F by this prospectus supplement. We refer to the
medium-term Senior Notes, Series F as the Senior Notes, the medium-term
Subordinated Notes, Series F as the Subordinated Notes and the Senior Notes and
the Subordinated Notes together as the Notes.

      We will sell the Notes in issuances consisting of one or more Notes having
the same issue date. We will establish the specific terms of each issuance of
Notes when we issue those Notes and describe those terms in the pricing
supplement.

      The interest rate on the Notes, except zero-coupon Notes, will either be a
fixed rate or a variable rate. Variable interest rates will be based on the
interest rate index or other formula specified in the pricing supplement.
Zero-coupon Notes will be issued at a price lower than the principal amount
payable at that Note's stated maturity, that is, the date specified in the
pricing supplement as the date on which the principal amount of the Note is
payable. We will not pay interest on zero-coupon Notes prior to their maturity,
that is, the date on which the unpaid principal amount of those Notes actually
becomes due and payable. As described below, we may also issue original issue
discount Notes or indexed notes, which may or may not be zero-coupon Notes.

      Each of the Senior Notes and the Subordinated Notes constitutes a single
series for purposes of the applicable Indenture and may be issued in an
aggregate principal amount of up to $3,250,000,000 for the Senior Notes and the
Subordinated Notes. Citicorp can reduce or increase these limits. No reduction,
however, will affect any outstanding Note or any Note as to which Citicorp has
accepted an offer to purchase. See "Plan of Distribution" on page S-24.

                                     RANKING

      The Senior Notes will be unsecured and will rank equally with all other
unsecured and unsubordinated indebtedness of Citicorp. The Subordinated Notes
will be unsecured and will rank equally with all other unsecured and
subordinated indebtedness of Citicorp, other than any subordinated indebtedness
that Citicorp designates at its issuance as junior to the Subordinated Notes.

                                  DENOMINATIONS

      We will issue Notes denominated in U.S. dollars only in denominations of
$50,000 and integral multiples of $1,000 in excess of $50,000.

                                 FORMS OF NOTES

      The Notes will be issued in fully registered form and will be represented
by one or more global Notes registered in the name of The Depository Trust
Company, as securities depositary. We will indicate in a pricing supplement if
the related issue of Notes will be issued in definitive form. We refer to The
Depository Trust Company as the Depositary and each beneficial interest in a
global Note as a book-entry Note.

      The description of the Notes in this prospectus supplement applies to
definitive Notes and to any global Note or Notes representing book-entry Notes.
For a description of special provisions that apply to book-entry Notes, see
"Book-Entry Notes" on page S-14 below.

                          ORIGINAL ISSUE DISCOUNT NOTES

      We may issue Notes as original issue discount Notes. An original issue
discount Note is a Note, including a zero-coupon Note, that is


                                      S-5
<PAGE>

issued at a price lower than the principal amount payable at its stated
maturity. Upon redemption or acceleration of the stated maturity of an original
issue discount Note, an amount less than the principal amount payable at its
stated maturity, as determined in accordance with its terms, becomes due and
payable.

      Original issue discount Notes, as well as other Notes offered under this
prospectus supplement, may, for United States federal income tax purposes, be
considered discount Notes. Some holders of, or owners of beneficial interests
in, original issue discount Notes that have a stated maturity of more than one
year from their date of issue must include original issue discount in income as
it accrues, generally before they receive the cash attributable to that income.

                                  INDEXED NOTES

      Citicorp may issue Notes as indexed notes. Holders of indexed Notes may
receive a principal amount at maturity that is greater or less than the face
amount of those Notes, depending upon the fluctuation of the relative value,
rate or price of the specified index, which may include one or more securities,
commodities or currencies. The pricing supplement relating to an issue of
indexed Notes will describe:

o     how we will determine the principal amount that is payable at maturity and
      any interest that is payable;

o     historical information regarding the relative value, rate or price of the
      specified index;

o     the face amount of the indexed Note;

o     any related principal U.S. federal income tax considerations;

o     if applicable, risk factors relating to an investment in the indexed
      Notes; and

o     how the amount of principal or interest payable will be calculated if the
      specified index becomes unavailable.

                                   REDEMPTION

      If Citicorp can redeem a Note before its stated maturity, the pricing
supplement will indicate:

      o     at what times and prices it may exercise that right of redemption;
            and

      o     if the redemption may be made in whole or in part.

      If the holder of a Note can obligate Citicorp to redeem or purchase a Note
before its stated maturity, the pricing supplement will indicate:

      o     at what times and prices the holder may exercise that right;

      o     whether the redemption or purchase may be made in whole or in part;
            and

      o     the other terms and provisions of that obligation.

                                PAYMENTS ON NOTES

      Unless otherwise specified in the pricing supplement, the Notes will be
denominated in U.S. dollars and payments of principal of and any premium or
interest will be made in U.S. dollars.

      Citibank, acting as paying agent, will make payments on the Notes at the
office it designates in New York City. It will make these payments in
immediately available funds to holders that present their Notes to the paying
agent in time for payment to be made in immediately available funds in
accordance with its normal payment procedures.

                            REGISTRATION AND TRANSFER

      A holder may present a definitive registered Note for registration of
transfer or exchange at the offices of Citibank, acting as security registrar
and transfer agent, at the office Citibank designates in New York City.


                                      S-6

INTEREST

      Each Note, except a zero-coupon Note, will bear interest at either a fixed
rate or a variable rate. We refer to a Note that bears interest at a fixed rate
as a fixed rate Note and a Note that bears interest at a variable rate as a
floating rate Note. We will not pay interest on zero-coupon Notes prior to their
maturity.

      Under no circumstances will any Note bear interest at a rate higher than
the maximum rate permitted by applicable law. Under present New York law, the
maximum rate of interest is 25% per annum on a simple interest basis. This limit
does not apply to Notes in which the buyer invests $2,500,000 or more.

                         INTEREST PERIODS, RECORD DATES,
                             INTEREST PAYMENT DATES

      Interest will accrue on each Note from and including its issue date to but
excluding that Note's first interest payment date and, in each successive
period, from and including an interest payment date to but excluding the next
interest payment date or at maturity. We refer to each period during which
interest accrues as an interest period. Interest on a Note will be due and
payable on each interest payment date and at maturity. We will indicate in the
applicable pricing supplement the interest payment dates and maturity for that
Note.

      Generally, we will pay interest to the person in whose name a Note is
registered at the close of business on the record date immediately preceding the
related interest payment date. However, we will pay interest at maturity to the
person to whom principal on that Note will be payable. The record date for each
interest payment date is the date 15 calendar days prior to that interest
payment date.

FIXED RATE NOTES

      For each issuance of fixed rate Notes, we will designate in the pricing
supplement the fixed rate of interest at which interest will accrue on that
Note. Interest payments for fixed rate Notes will be equal to the amount of
interest accrued from the last interest payment date, or the Notes' issue date
for the first interest period, to but excluding the next interest payment date,
computed using a 360-day year of twelve 30-day months.

      We will pay interest on fixed rate Notes semi-annually and at maturity. If
an interest payment date for a fixed rate Note falls on a day that is not a
market day, that is, a Saturday, Sunday or other day on which banks generally
may or must be closed in New York City, the related payment will be made on the
next market day and no additional interest will accrue as a result of the delay.

FLOATING RATE NOTES

      INTEREST RATES

      For each issuance of floating rate Notes, we will designate in the pricing
supplement the interest rate index on which interest will be based. The interest
rate index may be based on:

o     the commercial paper rate;

o     the London interbank offered rate (or LIBOR);

o     the treasury rate;

o     the certificate of deposit (or CD) rate;

o     the federal funds effective rate;

o     the prime rate;

o     the constant maturity treasury (or CMT) rate; or

o     another interest rate index or formula that we describe in the pricing
      supplement.

      TERMS OF FLOATING RATE NOTES

      We will indicate the following terms for an issuance of floating rate
Notes in the pricing supplement:

o     issue date--the date on which the Notes are issued;

o     calculation date--the date on which the interest


                                      S-7
<PAGE>

      rate for an interest determination date will be calculated;

o     spread--the number of basis points to be added to or subtracted from the
      interest rate index;

o     spread multiplier--the percentage to be multiplied by the interest rate
      index;

o     initial interest rate--the interest rate in effect from the issue date to
      the first interest reset date;

o     maximum interest rate--the maximum numerical interest rate, or ceiling, if
      any, at which interest may accrue during any interest period;

o     minimum interest rate--the minimum numerical interest rate, or floor, if
      any, at which interest may accrue during any interest period;

o     interest payment dates;

o     record dates;

o     index maturity--the period to maturity of the instrument on which the
      Note's interest rate index is based;

o     interest reset dates--the dates on which the interest rate is reset; and

o     interest determination dates--the dates as of which the interest rate in
      effect on an interest reset date is determined.

      INTEREST RESET DATES

      The interest rate on a floating rate Note may be reset daily, weekly,
monthly, quarterly, semi-annually or annually. The interest rate in effect on
the tenth day before a Note's maturity will apply to the ten days preceding that
Note's maturity. If an interest reset date for a floating rate Note is not a
market day, the interest reset date for that floating rate Note will be the next
market day. In the case of a LIBOR Note, if the next market day--which must also
be a London market day (that is, a day on which dealing in U.S. dollars take
place in the London interbank market) --falls in the next calendar month, the
interest reset date will be the immediately preceding London market day.

      INTEREST DETERMINATION DATES AND PAYMENTS

      If an interest payment date or maturity date for a floating rate Note,
other than a LIBOR Note, falls on a day that is not a market day, we will pay
interest due on that day on the next market day. If an interest payment date for
a LIBOR Note (1) does not fall on a London market day, and (2) the next London
market day falls in the next calendar month, then we will pay interest due on
that interest payment date on the preceding London market day. Additional
interest will accrue as a result of the resulting delay in payment, unless that
delay occurs at the maturity of the LIBOR Note.

      The interest determination date for a floating rate Note other than a
treasury rate Note will be the second market day before the related interest
reset date. The interest determination date for a treasury rate Note will be the
day of the week on which Treasury bills are auctioned in the week in which the
related interest reset date falls. Treasury bills are normally sold at auction
on Monday of each week. However, if that Monday is a legal holiday, the auction
is usually held on the next Tuesday or, sometimes, on the preceding Friday. If
an auction is held on the preceding Friday because of a legal holiday, that
Friday will be the interest determination date for the interest reset date
occurring in the following week. If an auction date falls on a day that would
otherwise be an interest reset date for a treasury rate Note, then the interest
reset date will be the first market day after that auction date.

      Interest payments for a floating rate Note will be the amount of interest
accrued to, but excluding, the interest payment date or maturity. However, if
the interest reset dates for a floating rate Note are daily or weekly, interest
payable on an interest payment date for that Note, other than interest payable
when principal on that Note is


                                      S-8
<PAGE>

also payable, will only include interest accrued to and including the previous
record date.

      CALCULATIONS OF INTEREST

      We will calculate accrued interest on a floating rate Note by multiplying
the face amount of the Note by an accrued interest factor. The accrued interest
factor is the sum of the daily interest factors for each day from the issue
date, or from the last date to which interest has been paid or provided for, to
the date for which accrued interest is being calculated. The daily interest
factor for a day is the annual interest rate applicable to that day divided by
360, or, in the case of treasury rate Notes or CMT rate Notes, divided by the
actual number of days in the year.

      We will round all percentages resulting from any calculation on floating
rate Notes to the nearest one-hundred thousandth of a percentage point, with
five one-millionths of a percentage point rounded upwards. We will round all
dollar amounts used in or resulting from any calculation to the nearest cent,
with one-half cent being rounded upwards.

      At the request of the holder of a floating rate Note, Citibank, which we
have appointed as calculation agent for the Notes, will provide the interest
rate then in effect on that Note and, if it has been determined, the interest
rate that will become effective for the next interest period.

      We use the following terms to explain how we will determine the interest
rate on the types of floating rate Notes that we describe in detail below:

      Money market yield is a yield, expressed as a percentage, calculated in
accordance with the following formula:

                      [D  x  360]
Money market yield = --------------- x 100
                     [360 - (D x M)]

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

Composite Quotations means the daily statistical release entitled "Composite
3:30 P.M. Quotations for U.S. Government Securities", or any successor
publication, published by the Federal Reserve Bank of New York.

H.15(519) means the weekly statistical release entitled "Statistical Release
H.15(519), Selected Interest Rates", or any successor publication, published by
the Board of Governors of the Federal Reserve System.

      COMMERCIAL PAPER RATE NOTES

      Interest will accrue on each commercial paper rate Note at an interest
rate based on the commercial paper rate and the spread and/or spread multiplier
specified in the pricing supplement.

      Commercial paper rate for an interest determination date means:

1.    the money market yield published on that date in H.15(519) under
      "Commercial Paper-Nonfinancial" for commercial paper with the index
      maturity; or

2.    if the rate described in clause (1) is not published by 9:00 A.M., New
      York City time, on the calculation date for that date, then the commercial
      paper rate will be the money market yield on that date for commercial
      paper having the index maturity published on that date in Composite
      Quotations under "Commercial Paper"; or

3.    if the rate described in clause (2) is not published in Composite
      Quotations by 3:00 P.M., New York City time, on the calculation date for
      that interest determination date, then the calculation agent will
      determine the commercial paper rate by

            first, selecting three leading dealers of commercial paper in New
      York City who are providing offered rates, as of 11:00 A.M.,


                                      S-9
<PAGE>

      New York City time, on the related interest determination date for
      commercial paper, with the index maturity, of an industrial issuer whose
      senior unsecured bond rating is Aa or its equivalent from a nationally
      recognized rating agency,

            second, computing the mean of those offered rates, and

            third computing the money market yield of that mean; or

4.    if the dealers selected by the calculation agent in clause (3) are not
      quoting the necessary offered rates on that calculation date, the
      commercial paper rate will be the commercial paper rate determined on the
      prior interest determination date.

      LIBOR Notes

      Interest will accrue on each LIBOR Note at an interest rate based on LIBOR
and the spread and/or spread multiplier specified in the pricing supplement.

      LIBOR for an interest determination date means:

1.    either (a) the rate for deposits in U.S. dollars having the index
      maturity, commencing on the second market day after that date, that
      appears on Telerate Page 3750 as of 11:00 A.M., London time, on that date,
      or (b) if we specify in the pricing supplement, the mean of the offered
      rates for deposits in U.S. dollars with the index maturity, commencing on
      the second market day after that date, which appear on the Reuters Screen
      LIBO Page as of 11:00 A.M., London time, on that date, if at least two
      offered rates appear on the Reuters Screen LIBO Page; or

2.    if the rate described in (a) of clause (1) does not appear on Telerate
      Page 3750 as specified, or if the Reuters Screen LIBO was specified in the
      pricing supplement and the rate described in (b) of clause (1) does not
      appear, the calculation agent will determine LIBOR on the basis of the
      rates on that date, at approximately 11:00 A.M., London time, at which
      deposits in U.S. dollars with the index maturity, commencing on the second
      market day after that date and in a principal amount of not less than
      $1,000,000 that is representative for a single transaction in such market
      at that time, are offered to prime banks in the London interbank market by
      four major banks in the London interbank market selected by the
      calculation agent.

      In this case, the calculation agent will request the principal London
      office of each of the major banks to provide a quotation of its rate. If
      at least two quotations are provided, LIBOR for that date will be the mean
      of those quotations; or

3.    if fewer than two quotations are provided in the manner described in
      clause (2), LIBOR for that date will be the mean of the rates quoted at
      approximately 11:00 A.M., New York City time, on that date by three major
      banks in New York City selected by the calculation agent for loans in U.S.
      dollars to leading European banks having the index maturity, commencing on
      the second market day after that date, and in a principal amount of not
      less than $1,000,000 that is representative for a single transaction in
      such market at that time; or

4.    if the banks selected as described in clause (3) are not quoting the
      requested rates, LIBOR will be LIBOR determined on the prior interest
      determination date.

In determining LIBOR:

Reuters Screen LIBO Page means the display designated as page LIBO on the
Reuters Monitor Money Rates Service, or on a successor page, or on a comparable
page selected by the calculation agent from another service that displays London
interbank offered rates or major bank offered rates; and

Telerate Page 3750 means the display page designated with that title on the
Telerate service or on a successor page.

      TREASURY RATE NOTES

      Interest will accrue on each treasury rate Note at an interest rate based
on the treasury rate and the spread and/or spread multiplier specified in the
pricing supplement.

      Treasury rate for an interest determination date means:

1.    the rate published on that date in H.15(519) under "U.S. Government
      Securities/Treasury Bills/Auction Average (Investment)" for the most
      recent auction of U.S. treasury bills with the index maturity; or

2.    if the rate described in clause (1) is not published by 3:00 P.M., New
      York City time, on the calculation date for that interest determination

      equivalent, on the basis of a year of 365 or 366 days, as applicable, and
      applied on a daily basis, for the auction described in clause (1) as
      otherwise announced by the U.S. Department of the Treasury; or

3.    if the results of the auction described in clause (1) are neither
      published nor announced by 3:00 P.M., New York City time, on the
      calculation date, or if no auction is held in that week, then the treasury
      rate will be calculated by the calculation agent as the yield to maturity,
      expressed as a bond equivalent, on the basis of a year of 365 or 366 days,
      as applicable, and applied on a daily basis, of the mean of the secondary
      market bid rates at approximately 3:30 P.M., New York City time, on that
      date, of three leading primary U.S. government securities dealers selected
      by the calculation agent for the issue of Treasury bills with a remaining
      maturity closest to the index maturity; or

4.    if the dealers selected by the calculation agent as described in clause
      (3) are not quoting those bid rates, the treasury rate will be the
      treasury rate determined on the prior interest determination date.

      Quotations under the heading "Certificates of Deposit" for negotiable
      certificates of deposit with the index maturity; or

3.    if the rate described in clause (2) is not published in Composite
      Quotations by 3:00 P.M., New York City time, on the calculation date, the
      CD rate will be calculated by the calculation agent as the mean of the
      secondary market offered rates as of 10:00 A.M., New York City time, on
      that date, of three leading non-bank dealers of negotiable U.S. dollar
      certificates of deposit in New York City selected by the calculation agent
      for negotiable certificates of deposit of major U.S. money market banks in
      the market for negotiable certificates of deposit, with a remaining
      maturity closest to the index maturity in a denomination of $5,000,000; or

4.    if the dealers selected by the calculation agent are not quoting the rates
      described in clause (3), the CD rate will be the CD Rate determined on the
      prior interest determination date.

      FEDERAL FUNDS RATE NOTES

      Interest will accrue on each federal funds


                                      S-11

      Federal funds effective rate for an interest determination date means:

1.    the rate published on that date for federal funds with the index maturity
      in H.15(519) under "Federal Funds (Effective)"; or

2.    if the rate described in clause (1) is not published by 3:00 P.M., New
      York City time, on the calculation date for that interest determination
      date, the federal funds effective rate will be the rate on that date
      published in Composite Quotations under "Federal Funds/Effective Rate"; or

3.    if the rate described in clause (2) is not published in Composite
      Quotations by 3:00 P.M., New York City time, on the calculation date, the
      federal funds effective rate for that date will be calculated by the
      calculation agent as the mean of the rates for the last transaction in
      overnight U.S. dollar federal funds arranged by three leading brokers of
      federal funds transactions in New York City selected by the calculation
      agent prior to 9:00 A.M., New York City time, on that date; or

4.    if the brokers selected by the calculation agent as described in clause
      (3) are not quoting that rate, the federal funds effective rate will be
      the federal funds effective rate determined on the prior interest
      determination date.

      PRIME RATE NOTES

      Interest will accrue on each prime rate Note at an interest rate based on
the prime rate and the spread and/or spread multiplier specified in the pricing
supplement.

      Prime rate for an interest determination date means:

1.    the rate published on that date in H.15(519) under "Bank Prime Loan"; or

2.    if the rate described in clause (1) is not published prior to 3:00 P.M.,
      New York City time, on the calculation date for that interest
      determination date, then the calculation agent will determine the prime
      rate as the mean of the rates of interest publicly announced by each bank
      that appears on the Reuters Screen USPRIME1 Page as that bank's prime rate
      or base lending rate as in effect for that date; or

3.    if fewer than four rates but more than one rate appear on the Reuters
      Screen USPRIME1 Page as described in clause (2), the prime rate will be
      determined by the calculation agent as the mean of the prime rates quoted
      as of the close of business on that date by four major money center banks
      in New York City selected by the calculation agent, on the basis of the
      actual number of days in the year divided by a 360-day year; or

4.    if fewer than two rates appear on the Reuters Screen USPRIME1 Page as
      described in clause (3), the prime rate will be determined by the
      calculation agent on the basis of the prime rates furnished in New York
      City by the appropriate number of substitute banks or trust companies
      organized and doing business under U.S. or state law, having total equity
      capital of at least $500,000,000 and regulated by a federal or state bank

5.    if the banks selected as described in clause (4) are not quoting such
      rate, the prime rate will be the prime rate determined on the prior
      interest determination date.

In determining the prime rate, Reuters Screen USPRIME1 Page means the display
page designated as "USPRIME1" on the Reuters Monitor Money Rates Service, or
another page that may replace the USPRIME1 page on that service for displaying
prime rates or base lending rates of major U.S. banks.

      CMT RATE NOTES

      Interest will accrue on each CMT rate


                                      S-12
<PAGE>

Note at an interest rate based on the CMT rate and the spread and/or spread
multiplier specified in the pricing supplement.

      CMT rate for an interest determination date means:

1.    the rate displayed on the Designated CMT Telerate Page under ". . .
      Treasury Constant Maturities . . . Federal Reserve Board Release H.15 . .
      . Mondays Approximately 3:45 P.M.", under the column for the index
      maturity for (a) if the Designated CMT Telerate Page is 7055, that date or
      (b) if the Designated CMT Telerate Page is 7052, the week, or the month,
      as set forth in the pricing supplement, ended immediately before the week
      in which that interest determination date occurs; or

2.    if the rate described in clause (1) is no longer displayed on the relevant
      page, or if it is not displayed by 3:00 P.M., New York City time, on the
      related calculation date, then the CMT rate for that date will be the
      treasury constant maturity rate for the index maturity published in the
      relevant H.15(519); or

3.    if the rate described in clause (2) is no longer published, or if it is
      not published by 3:00 P.M., New York City time, on the related calculation
      date, then the CMT rate for that date will be the treasury constant
      maturity rate for the index maturity, or other U.S. treasury rate for the
      index maturity, for that date then published by either the Federal Reserve
      Board or the Department of the Treasury that the calculation agent
      determines to be comparable to the rate formerly displayed on the
      Designated CMT Telerate Page and published in the relevant H.15(519); or

4.    if the information described in clause (3) is not provided by 3:00 P.M.,
      New York City time, on the related calculation date, then the CMT rate for
      that date will be calculated by the calculation agent as a yield to
      maturity, based on the mean of the secondary market closing offer-side
      prices reported as of approximately 3:30 P.M., New York City time, on that
      date by five Reference Dealers in New York City selected by the
      calculation agent, after first eliminating the high and low quotations,
      for the most recently issued direct noncallable fixed rate treasury notes
      issued by the Department of the Treasury with an original maturity of
      approximately the index maturity and a remaining term to maturity of not
      less than the index maturity minus one year. If two treasury notes have
      remaining terms to maturity equally close to the index maturity, the
      quotes for the treasury note with the shorter remaining term to maturity
      will be used; or

5.    if the calculation agent cannot obtain the quotations described in clause
      (4), the CMT rate for that date will be calculated as the yield to
      maturity based on the mean of the secondary market closing offer side
      prices as of approximately 3:30 P.M., New York City time, reported on that
      date by five Reference Dealers in New York City selected by the
      calculation agent, after first eliminating the high and low quotations,
      for treasury notes with an original maturity of the number of years that
      is the next highest to the index maturity and a remaining term to maturity
      closest to the index maturity and in an amount of at least $100,000,000.
      If three or four of the Reference Dealers are quoting that rate, then the
      CMT rate will be based on the mean of the offer prices obtained and
      neither the highest nor the lowest of those quotes will be eliminated; or

6.    if fewer than three Reference Dealers selected by the calculation agent
      are quoting rates as described in clause (5), the CMT rate will be the CMT
      rate determined on the prior interest determination date.

In determining the CMT rate:

Designated CMT Telerate Page means the display on the Telerate service on the
page designated in the pricing supplement, or another page that may replace that
page on that service for the purpose of displaying Treasury Constant Maturities
as reported in H.15(519), for the purpose of displaying Treasury Constant
Maturities as reported in H.15(519). If no page is specified in the pricing
supplement, the Designated CMT


                                      S-13

Telerate Page will be 7052 for the most recent week; and

Reference Dealers means a leading primary U.S. government securities dealer.

BOOK-ENTRY NOTES

      When issued, all book-entry Notes of the same series will be represented
by one or more permanent global Notes in registered form, without interest
coupons. These global Notes are referred to throughout this prospectus
supplement as the global Notes. Each global Note will be deposited with and
registered in the name of the Depositary.

      Ownership of book-entry Notes will be limited to participants in the
Depositary, which are securities intermediaries that have accounts with the
Depositary, or to persons that hold book-entry Notes through participants.
Ownership of book-entry Notes by participants will be evidenced only by and
transfers of those Notes will be made only through records maintained by the
Depositary. Ownership of book-entry Notes by persons that hold through a
participant will be evidenced only by and transfers of those Notes within that
participant will be made only through entries on that participant's records. The
laws of some jurisdictions require some purchasers of securities to take
physical delivery of their securities in definitive form. These laws may impair
the ability to transfer book-entry Notes.

      When Citicorp issues and deposits a global Note with the Depositary, the
Depositary will immediately credit the appropriate principal amounts of the
book-entry Notes represented by that global Note to the accounts of its
participants. The soliciting Agent or Citicorp, if it sells those Notes
directly, will designate the accounts to be credited.

      Citicorp will pay to the Depositary all principal of and any premium and
interest on book-entry Notes represented by global Notes registered in the name
of the Depositary. These payments will be made in immediately available funds at
the office of Citibank, acting as paying agent, that it designates for that
purpose in New York City.

      None of Citicorp, either trustee or any agent of Citicorp or either
trustee is responsible for the Depositary's records or any participant's records
relating to payments made on book-entry Notes or for maintaining, supervising or
reviewing any of the Depositary's or any participant's records relating to those
book-entry Notes.

      Immediately upon receipt of any payment of principal of or any premium or
interest on a global Note, the Depositary will credit the accounts of the
appropriate participants to reflect the participants' proportionate interests in
the principal amount of the global Note as shown on the records of the
Depositary. Payments by participants to owners of book-entry Notes held through
those participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of customers
registered in street name and will be the responsibility of those participants.

      No global Note described above may be transferred except as a whole by the
Depositary.

      Book-entry Notes represented by a global Note will be exchanged for
definitive Notes in registered form only if:

1.    the Depositary notifies Citicorp that it is unwilling or unable to
      continue as Depositary for that global Note;

2.    the Depositary ceases to be a clearing agency registered under the
      Securities Exchange Act of 1934;

3.    Citicorp elects to permit those book-entry Notes to be exchanged for
      definitive Notes in registered form; or

4.    an event has happened and is continuing that, after notice or lapse of
      time, would become an Event of Default for those Notes.

      Definitive Notes issued in exchange for a global Note will be in
registered form, of the same


                                      S-14
<PAGE>

tenor and aggregate principal amount as that global Note, in denominations of
$50,000 and integral multiples of $1,000 in excess of $50,000.

      Definitive Notes will be registered in the manner specified by the
Depositary, based on directions that the Depositary receives from its
participants.

      Except as provided above, owners of book-entry Notes will not be entitled
to receive physical delivery of Notes in definitive form and will not be
considered the holders of Notes for any purpose under the applicable Indenture.
Except as provided above, no global Note representing book-entry Notes will be
exchangeable, except for another global Note of the same denomination and tenor
to be registered in the name of the Depositary.

      Accordingly, each person owning a book-entry Note must rely on the
procedures of the Depositary to exercise any rights of a holder under the
applicable Indenture. In addition, each person that is not a participant must
rely on the procedures of the participant through which that person owns its
interest. Each Indenture provides that the Depositary, as a holder, may appoint
agents and otherwise authorize participants to take any actions that a holder is
entitled to take under the applicable Indenture.

      Under existing industry practices, if Citicorp requests any action of
holders or if owners of a book-entry Note desire to take action under the
Indenture, the Depositary would authorize the participants owning the book-entry
Notes to take that action. Those participants would then authorize the
beneficial owners of those book-entry Notes to take that action or would
otherwise act upon the instructions of beneficial owners owning through them.

      The Depositary 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 Securities Exchange Act of 1934.

      The Depositary was created to hold securities of its participants and to
facilitate the clearance and settlement of securities transactions among its
participants through electronic book-entry changes in the accounts of those
participants, eliminating the need for physical movement of securities
certificates. The Depositary's participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and other organizations,
some of which own the Depositary. Access to the Depositary's book-entry system
is also available to others, including banks, brokers, dealers and trust
companies, that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.

      The Depositary is aware that some computer applications and systems for
processing dates that are dependent upon calendar dates, particularly dates on
and after January 1, 2000, may encounter Year 2000 problems. The Depositary has
informed its participants and other members of the financial community that it
has developed and is implementing a program so that its systems, as they relate
to the timely payment of distributions to securityholders, book-entry
deliveries, and settlement of trades within the Depositary, continue to function
appropriately. This program includes a technical assessment and a remediation
plan, each of which is complete. The Depositary expects the testing phase of its
plan to be completed within appropriate time frames.

      However, the Depositary's ability to perform its services properly also
depends upon the remediation of Year 2000 problems by other parties that
interact with the Depositary. These parties include issuers, their agents, third
party vendors from whom the Depositary licenses software and hardware, and third
party vendors on whom the Depositary relies for information or the provision of
services, including telecommunication and electrical utility service providers.
The Depositary is contacting and will continue to contact third party vendors
to: (1) impress upon them the importance of their services being Year 2000
compliant and (2) determine the extent of their efforts for Year 2000
remediation and testing of their services.

      UNITED STATES TAXATION

      The following summary of principal U.S. federal income tax consequences of
owning Notes may be relevant to you if you acquire Notes at issuance and you own
your Notes as capital assets for tax purposes.

      Our summary does not apply to you if:

o     you are not a U.S. holder, a U.S. holder being a beneficial owner of a
      Note that is:

      1.    a citizen or resident of the United States;

      2.    a domestic corporation;

      3.    an estate whose income is taxable by the United States regardless of
            the source of the income; or

      4.    a trust (a) whose administration a U.S. court can exercise primary
            supervision over and (b) over which one or more U.S. persons are
            authorized to control all substantial decisions; or

o     you are a member of a class of holders affected by special rules,
      including:

      1.    a dealer in securities or currencies;

      2.    a trader in securities that elects to use a mark-to-market method of
            accounting for your securities holdings;

      3.    a bank;

      4.    a life insurance company;

      5.    a tax-exempt organization;

      6.    a person that owns Notes that are a hedge or that are hedged against
            interest rate or currency risks;

      7.    a person that owns Notes as part of a straddle or conversion
            transaction for tax purposes; or

      8.    a person whose functional currency for tax purposes is not the U.S.
            dollar.

      Our summary deals only with Notes that are due to mature 30 years or less
from the date on which they are issued. The U.S. federal income tax consequences
of owning Notes that are due to mature more than 30 years from their date of
issue will be discussed in the pricing supplement applicable to the issuance of
those Notes.

      Our summary is based on the Internal Revenue Code of 1986, its legislative
history, existing and proposed regulations under the Internal Revenue Code,
published rulings and court decisions, all as in effect on the date of this
prospectus supplement. These laws may change, possibly on a retroactive basis.

      YOU SHOULD CONSULT YOUR OWN TAX ADVISOR TO DETERMINE EXACTLY HOW OWNING
THESE NOTES AFFECTS YOUR TAX LIABILITY.

PAYMENTS OF INTEREST

      Except as described below in the case of interest on a discount Note that
is not qualified stated interest, interest on your Note will be taxed as
ordinary income at the time you receive it or it accrues, depending on your
method of accounting for tax purposes.

      CASH BASIS TAXPAYERS

      If you are a taxpayer that uses the cash receipts and disbursements method
of accounting for tax purposes and you receive an interest payment that is
denominated in, or determined on the basis of, a foreign currency, you must
recognize income equal to the U.S. dollar value of the interest payment, based
on the exchange rate in effect on the date of receipt, regardless of


                                      S-16
<PAGE>

whether you actually convert the payment into U.S. dollars.

      ACCRUAL BASIS TAXPAYERS

      If you are a taxpayer that uses an accrual method of accounting for tax
purposes, you may determine the amount of income that you recognize with respect
to an interest payment denominated in, or determined on the basis of, a foreign
currency by using one of two methods.

      Under the first method, you will determine the amount of income accrued
based on the average exchange rate in effect during the interest accrual period
or, if an accrual period spans two taxable years, that part of the period within
the taxable year.

      If you elect the second method, you will determine the amount of income
accrued on the basis of the exchange rate in effect on the last day of the
accrual period or, if an accrual period spans two taxable years, the exchange
rate in effect on the last day of the part of the period within the taxable
year. Additionally, under this second method, if you receive a payment of
interest within five business days of the last day of your accrual period or
taxable year, you may instead translate the interest accrued into U.S. dollars
at the exchange rate in effect on the day that you actually receive the interest
payment. If you elect the second method it will apply to all debt instruments
that you own at the beginning of the first taxable year to which the election
applies and to all debt instruments that you thereafter acquire. You may not
revoke this election without the consent of the Internal Revenue Service.

      When you actually receive an interest payment, including a payment
attributable to accrued but unpaid interest upon the sale or retirement of your
Note, denominated in or determined on the basis of a foreign currency for which
you accrued an amount of income, you will recognize ordinary income or loss
measured by any difference between the exchange rate that you used to accrue
interest income and the exchange rate in effect on the date of receipt,
regardless of whether you actually convert the payment into U.S. dollars.

ORIGINAL ISSUE DISCOUNT

      If you own a Note, other than a short-term Note with a term of one year or
less, it will be treated as a discount Note--a Note issued at an original issue
discount--if its stated redemption price at maturity exceeds its issue price by
more than a de minimis amount. Generally, a Note's issue price will be the first
price at which a substantial amount of Notes included in the issue of which the
Note is a part are sold to persons other than bond houses, brokers, or similar
persons or organizations acting in the capacity of underwriters, placement
agents, or wholesalers. A Note's stated redemption price at maturity is the
total of all payments provided by the Note that are not payments of qualified
stated interest. Generally, an interest payment on a Note is qualified stated
interest if it is part of a series of stated interest payments on a Note that
are unconditionally payable at least annually at a single fixed rate--with
exceptions for lower rates paid during some periods--applied to the outstanding
principal amount of the Note. There are special rules for variable rate Notes
that we discuss below under "Variable Rate Notes" on page S-21.

      In general, your Note is not a discount Note if the amount by which its
stated redemption price at maturity exceeds its issue price is less than the de
minimis amount--1/4 of 1 percent of its stated redemption price at maturity
multiplied by the number of complete years to its maturity. Your Note will have
de minimis original issue discount if the amount of the excess is less than the
de minimis amount. If your Note has de minimis original issue discount, you must
include it in income as stated principal payments are made on the Note, unless
you make the election described below under "Election to Treat All Interest as
Original Issue Discount" on page S-21. You can determine the includible amount
for each payment by multiplying the total amount of your Note's de minimis
original issue discount by a fraction equal to:


                                      S-17
<PAGE>

      o     the amount of the principal payment made; divided by

      o     the total remaining stated principal amount of the Note immediately
            before the principal payment is made.

      INCLUSION OF ORIGINAL ISSUE DISCOUNT IN INCOME

      Generally, if your discount Note matures more than one year from its date
of issue, you must include original issue discount in income before you receive
cash attributable to that income. The amount of OID that you must include in
income is calculated using a constant-yield method, and generally you will
include increasingly greater amounts of OID in income over the life of your
discount Note. More specifically, you calculate the amount of OID that you must
include in income by adding the accrued OID--the daily portions of OID for your
discount Note for each day during the taxable year or portion of the taxable
year that you own your discount Note. You can determine the daily portion by
allocating to each day in any accrual period a pro rata portion of the OID
allocable to that accrual period. You may select an accrual period of any length
for your discount Note and you may vary the length of each accrual period over
the term of your discount Note. However, no accrual period may be longer than
one year and each scheduled payment of interest or principal on the discount
Note must occur on either the first or final day of an accrual period.

      You can determine the amount of OID allocable to an accrual period by:

      o     multiplying your discount Note's adjusted issue price at the
            beginning of the accrual period by your discount Note's yield to
            maturity; and then

      o     subtracting from this figure the sum of the payments of qualified
            stated interest on your discount Note allocable to the accrual
            period.

      You must determine the discount Note's yield to maturity on the basis of
compounding at the close of each accrual period and adjusting for the length of
each accrual period. Further, you determine your discount Note's adjusted issue
price at the beginning of any accrual period by:

      o     adding your discount Note's issue price and any accrued OID for each
            prior accrual period; and then

      o     subtracting any payments previously made on your discount Note that
            were not qualified stated interest payments.

      If an interval between payments of qualified stated interest on your Note
contains more than one accrual period, then, when you determine the amount of
OID allocable to an accrual period, you must allocate the amount of qualified
stated interest payable at the end of the interval, including any qualified
stated interest that is payable on the first day of the accrual period after the
interval, pro rata to each accrual period in the interval based on their
relative lengths. In addition, you must increase the adjusted issue price at the
beginning of each accrual period in the interval by the amount of any qualified
stated interest that has accrued prior to the first day of the accrual period
but that is not payable until the end of the interval. You may compute the
amount of OID allocable to an initial short accrual period by using any
reasonable method if all other accrual periods, other than a final short accrual
period, are of equal length.

      The amount of OID allocable to the final accrual period is equal to the
difference between:

      o     the amount payable at the maturity of your discount Note, other than
            any payment of qualified stated interest; and

      o     your discount Note's adjusted issue price as of the beginning of the
            final accrual period.


                                      S-18
<PAGE>

      ACQUISITION PREMIUM

      If you purchase your Note for an amount that is less than or equal to the
sum of all amounts, other than qualified stated interest, payable on your Note
after the purchase date but is greater than the amount of your Note's adjusted
issue price as determined above, the excess is acquisition premium. If you do
not make the election described below on page S-21 under "Election to Treat All
Interest as Original Issue Discount", then you must reduce the daily portions of
OID by an amount equal to:

      o     the excess of your adjusted basis in the Note immediately after
            purchase over the adjusted issue price of your Note; divided by

      o     the excess of the sum of all amounts payable, other than qualified
            stated interest, on your Note after the purchase date over your
            Note's adjusted issue price.

      MARKET DISCOUNT

      You will be treated as if you purchased your Note, other than a short-term
Note, at a market discount and your Note will be a market discount Note if:

      o     you purchase your Note for less than its issue price as determined
            above; and

      o     your Note's stated redemption price at maturity or, in the case of a
            discount Note, its revised issue price, exceeds the price you paid
            for it by at least 1/4 of 1 percent of its stated redemption price
            at maturity or revised issue price, in the case of a discount Note,
            multiplied by the number of complete years to maturity.

      To determine the revised issue price of your Note for these purposes, you
generally add any OID that has accrued on your Note to its issue price.

      If your Note's stated redemption price at maturity or, in the case of a
discount Note, its revised issue price, does not exceed the price you paid for
the Note by at least 1/4 of 1 percent multiplied by the number of complete years
to maturity, the excess constitutes de minimis market discount, and the rules
that we discuss below are not applicable to you.

      If you recognize gain on the maturity or disposition of your market
discount Note, you must treat it as ordinary income to the extent of the accrued
market discount on your Note. Alternatively, you may elect to include market
discount in income currently over the life of your Note. If you make this
election, it will apply to all debt instruments with market discount that you
acquire on or after the first day of the first taxable year to which the
election applies. You may not revoke this election without the consent of the
IRS. You will accrue market discount on your market discount Note on a
straight-line basis unless you elect to accrue market discount using a
constant-yield method.

      If you make this election to accrue market discount using a constant-yield
method, it will apply only to the Note for which it is made and you may not
revoke it. If you own a market discount Note and do not elect to include market
discount in income currently, you will generally be required to defer deductions
for interest on borrowings allocable to your Note in an amount not exceeding the
accrued market discount on your Note until the maturity or disposition of your
Note.

      PRE-ISSUANCE ACCRUED INTEREST

      An election can be made to decrease the issue price of your Note by the
amount of pre-issuance accrued interest if:

      o     a portion of the initial purchase price of your Note is attributable
            to pre-issuance accrued interest;

      o     the first stated interest payment on your Note is to be made within
            one year of your Note's issue date; and


                                      S-19
<PAGE>

      o     the payment will equal or exceed the amount of pre-issuance accrued
            interest.

      If this election is made, a portion of the first stated interest payment
will be treated as a return of the excluded pre-issuance accrued interest and
not as an amount payable on your Note.

      NOTES AFFECTED BY CONTINGENCIES, INCLUDING OPTIONAL REDEMPTION

      Your Note is affected by a contingency if it provides for one or more
alternative payment schedules that apply when a contingency occurs, whether that
contingency relates to payments of interest or of principal. In this situation,
you must determine the yield and maturity of your Note by assuming that the
payments will be made according to the payment schedule most likely to occur if:

      o     the timing and amounts of the payments that comprise each payment
            schedule are known as of the issue date; and

      o     one of the alternative payment schedules is significantly more
            likely to occur.

      These rules do not apply if the contingency is remote or incidental.

      If there is no single payment schedule that is significantly more likely
to occur--other than because of mandatory repurchases of Notes required to be
made before maturity by the terms of the offering--you must include income on
your Note in accordance with the general rules that govern contingent payment
obligations. These rules will be discussed in a pricing supplement.

      If your Note is affected by a contingency, and either you or Citicorp
holds one or more unconditional options that, if exercised, would require
payments to be made on the Note under one or more alternative payment schedules,
then:

      o     in the case of one or more options that Citicorp may exercise,
            Citicorp will be deemed to exercise or not exercise an option or
            combination of options in the manner that minimizes the yield on
            your Note; and

      o     in the case of an option that you may exercise, you will be deemed
            to exercise or not exercise an option or combination of options in
            the manner that maximizes the yield on your Note.

      If both you and Citicorp hold options described in the preceding sentence,
those rules will apply to each option in the order in which they may be
exercised. You may determine the yield on your Note for the purposes of those
calculations by using any date on which your Note may be redeemed or repurchased
as the maturity date and the amount payable on that date in accordance with the
terms of your Note as the principal amount payable at maturity.

      If a contingency, including the exercise of an option, actually occurs or,
contrary to an assumption made according to the above rules, does not occur,
then a change in circumstances has occurred. Except to the extent that a portion
of your Note is repaid as a result of the change in circumstances and solely to
determine the amount and accrual of OID, you must redetermine the yield and
maturity of your Note by treating your Note as having been retired and reissued
on the date of the change in circumstances for an amount equal to your Note's
adjusted issue price on that date.

      ELECTION TO TREAT ALL INTEREST AS ORIGINAL ISSUE DISCOUNT

      You may elect to include in gross income all interest that accrues on your
Note using the constant-yield method described above on page S-18 under the
heading "Inclusion of Original Issue Discount in Income", with the modifications
described below. For purposes of this election, interest will include stated
interest, acquisition


                                      S-20
<PAGE>

discount, OID, de minimis original issue discount, market discount, de minimis
market discount and unstated interest, as adjusted by any amortizable bond
premium or acquisition premium.

      If you make this election for your Note, then, when you apply the
constant-yield method:

      o     the issue price of your Note will equal your cost;

      o     the issue date of your Note will be the date you acquired it; and

      o     no payments on your Note will be treated as payments of qualified
            stated interest.

      Generally, this election will apply only to the Note for which you make
it; however, if the Note for which you made this election has amortizable bond
premium, you will be deemed to have made an election to apply amortizable bond
premium against interest for all debt instruments with amortizable bond premium,
other than debt instruments the interest on which is excludible from gross
income, that you own as of the beginning of the taxable year in which you
acquire the Note for which you made this election or that you thereafter
acquire. Additionally, if you make this election for a market discount Note, you
will be treated as having made the election discussed above on page S-19 under
"Market Discount" to include market discount in income currently over the life
of all debt instruments that you currently own or later acquire. You may not
revoke an election to apply the constant-yield method to all interest on a Note
or the deemed elections for amortizable bond premium or Market discount notes
without the consent of the IRS.

      VARIABLE RATE NOTES

      Your Note will be a variable rate Note if:

      o     your Note's issue price does not exceed the total noncontingent
            principal payments by more than a specified amount; and

      o     your Note provides for stated interest payments that are
            unconditionally payable at least annually at one or more qualifying
            variable rates.

      We expect that floating rate Notes generally will be treated as variable
rate Notes under the rules described below. We will discuss the U.S. federal
income tax consequences of any floating rate Note that does not qualify as a
variable rate Note in the pricing supplement.

      In general, if your variable rate Note bears interest at a single
qualifying variable rate, all stated interest on your Note is qualified stated
interest. In this case, the amount of OID, if any, is determined by using the
value of the rate on the issue date, if the variable rate reflects, or inversely
reflects, then current variations in the cost of newly borrowed funds and meets
other requirements, or the yield reasonably expected on your Note, if the
variable rate is determined on the basis of objective financial or economic
information that is not within the control of or unique to the circumstances of
the issuer or a related party.

      If your variable rate Note does not provide for stated interest at a
single qualifying variable rate, you generally must determine the interest and
OID accruals on your Note by:

      o     determining a fixed rate substitute for each variable rate provided
            under your variable rate Note;

      o     constructing an equivalent fixed rate Note, using the fixed rate
            substitute described above;

      o     determining the amount of qualified stated interest and OID for the
            equivalent fixed rate Note; and

      o     adjusting for actual variable rates during the applicable accrual
            period.

      When you determine the fixed rate substitute for each variable rate
provided under the variable rate Note, you generally will use the value


                                      S-21
<PAGE>

of each variable rate, depending on its type, as of the issue date or a rate
that reflects the yield reasonably expected on your Note. For this purpose, a
variable rate Note that provides for a fixed interest rate during any period is
treated as if it provided instead for a variable rate; the substitute variable
rate must be such that the fair market value of your variable rate Note as of
the issue date approximates the fair market value of an otherwise identical
Note.

      SHORT-TERM NOTES

      In general, if you are an individual or other cash basis U.S. holder of a
short-term Note, you are not required to accrue OID, as specially determined
below for purposes of this paragraph, for U.S. federal income tax purposes. You
may, however, elect to do so. You may also be required to include any stated
interest in income as you receive it.

      If you are

      o     an accrual basis taxpayer;

      o     a taxpayer in a special class, including a bank, regulated
            investment company, dealer in securities, common trust fund, a
            person who owns Notes as part of identified hedging transactions, or
            a pass-through entity specified in the Internal Revenue Code; or

      o     a cash basis taxpayer who elects to accrue OID;

you must accrue OID on short-term Notes on either a straight-line basis or under
the constant-yield method, based on daily compounding.

      If you are not required and do not elect to include OID in income
currently, any gain you realize on the sale or retirement of your short-term
Note will be ordinary income to the extent of the OID accrued on a straight-line
basis, unless you make an election to accrue the OID under the constant-yield
method, through the date of sale or retirement. In addition, if you are not
required and do not elect to accrue OID on your short-term Notes, you will be
required to defer deductions for interest on borrowings allocable to your
short-term Notes in an amount not exceeding the deferred income until the
deferred income is realized. When you determine the amount of OID under these
rules, you must include all interest payments on your short-term Note, including
stated interest, in your short-term Note's stated redemption price at maturity.

      FOREIGN CURRENCY DISCOUNT NOTES

      You must determine OID for any accrual period on your discount Note if it
is denominated in, or determined on the basis of, a foreign currency in that
foreign currency and then translate the amount of OID into U.S. dollars in the
same manner used to translate stated interest accrued by an accrual basis U.S.
holder, as described above on page S-17 under "Payments of Interest -- Accrual
Basis Taxpayers". You may recognize ordinary income or loss when you receive an
amount attributable to OID in connection with a payment of interest or the sale
or retirement of your Note.

NOTES PURCHASED AT A PREMIUM

      If you purchase your Note for an amount in excess of its principal amount,
you may elect to treat the excess as amortizable bond premium. If you make this
election, you will reduce the amount of interest on your Note that you must
include in income each year by the amount of amortizable bond premium allocable,
based on your Note's yield to maturity, to that year.

      If your Note is denominated in, or determined on the basis of, a foreign
currency, you will compute your amortizable bond premium in units of the foreign
currency and your amortizable bond premium will reduce your interest income in
units of the foreign currency. Gain or loss recognized that is attributable to
changes in exchange rates between the time your amortized bond premium offsets
interest income and the time of the acquisition of your Note when your amortized
bond premium offsets your interest


                                      S-22
<PAGE>

income is generally taxable as ordinary income or loss. If you make an election
to amortize bond premium, it will apply to all debt instruments, other than debt
instruments, the interest on which is excludible from gross income, that you own
at the beginning of the first taxable year to which the election applies, and to
all debt instruments that you thereafter acquire, and you may not revoke it
without the consent of the IRS.

PURCHASE, SALE AND RETIREMENT OF NOTES

      Your tax basis in your Note will generally be the U.S. dollar cost of your
Note, adjusted by:

      o     adding any OID or market discount, de minimis original issue
            discount and de minimis market discount previously included in
            income on your Note; and then

      o     subtracting the amount of any payments on your Note that are not
            qualified stated interest payments and the amount of any amortizable
            bond premium applied to reduce interest on your Note.

      If you purchase your Note with a foreign currency, the U.S. dollar cost of
your Note will generally be the U.S. dollar value of the purchase price on the
date of purchase.

      You will generally recognize gain or loss on the sale or retirement of
your Note equal to the difference between the amount you realize on the sale or
retirement and your tax basis in your Note. If your Note is sold or retired for
an amount in a foreign currency, the amount you realize will be the U.S. dollar
value of such amount on:

      o     the date payment is received, if you are a cash basis taxpayer; or

      o     the date of disposition, if you are an accrual basis taxpayer.

      You will recognize capital gain or loss when you sell your Note, or it is
retired, except to the extent:

      o     described above on page S-22 under "Original Issue Discount
            --Short-Term Notes" or on page S-19 under "Original Issue Discount
            --Market Discount";

      o     attributable to accrued but unpaid interest; or

      o     the rules governing contingent payment obligations apply.

      Capital gain of a noncorporate U.S. holder is generally taxed at a maximum
rate of 20% for property held more than one year.

      You must treat any portion of the gain or loss that you recognize on the
sale or retirement of a Note as ordinary income or loss to the extent
attributable to changes in exchange rates. However, you take exchange gain or
loss into account only to the extent of the total gain or loss that you realize
on the transaction.

EXCHANGE OF AMOUNTS IN CURRENCIES OTHER THAN U.S. DOLLARS

      If you receive foreign currency as interest on your Note or on the sale or
retirement of your Note, your tax basis in the foreign currency will equal its
U.S. dollar value when the interest is received or at the time of the sale or
retirement. If you purchase foreign currency you generally will have a tax basis
equal to the U.S. dollar value of the foreign currency on the date of your
purchase. If you sell or dispose of a foreign currency, including if you use it
to purchase Notes or exchange it for U.S. dollars, any gain or loss recognized
generally will be ordinary income or loss.

BACKUP WITHHOLDING AND INFORMATION REPORTING

      In general, if you are a noncorporate U.S. holder, we are required to
report to the IRS all payments of principal, any premium and interest on your
Note, the proceeds of the sale of your Note before maturity within the United
States, and the accrual of OID on a discount Note.


                                      S-23
<PAGE>

      Additionally, backup withholding at a rate of 31% will apply to any
payments, including payments of OID, if you fail to provide an accurate taxpayer
identification number, or you have been notified by the IRS that you have failed
to report all interest and dividends required to be shown on your federal income
tax returns.

      In general, both U.S. backup withholding and information reporting
requirements will apply to the payment of the proceeds from the sale of Notes to
or through a U.S. office of a broker.

                              PLAN OF DISTRIBUTION

      Citicorp may offer the Notes on a continuous basis through Salomon Smith
Barney Inc., as agent, under the terms of a selling agent agreement between
Citicorp and Salomon Smith Barney Inc. Citicorp may appoint additional agents to
sell the Notes by entering into a selling agent agreement with those agents. As
provided in the selling agent agreement, each agent will use its reasonable best
efforts when requested by Citicorp to solicit offers to purchase the Notes.

      Citicorp will pay each agent a commission or grant a discount ranging from
 .125% to 3.00% of the principal amount of each Note, depending on its stated
maturity, sold through that agent. Citicorp also may sell Notes to any agent,
acting as principal, at prices agreed upon at the time of sale, for resale to
investors or other purchasers at prices based on market prices at the time of
resale, as determined by that agent, or at a fixed public offering price.
Citicorp expects to receive proceeds from the sale of the Notes within the range
set forth on the cover page of this prospectus supplement.

      Each agent may sell the Notes to or through dealers who may resell those
Notes to investors. Each agent may pay all or part of their discount or
commission to those dealers. The agent may vary the offering price and other
selling terms when reselling the Notes.

      Citicorp may sell Notes directly to investors on its own behalf and enter
into agreements similar to the selling agent agreement with other parties.
Citicorp will not pay any commission nor grant any discount on any sale that it
makes directly.

      Citicorp has the sole right to accept offers to purchase Notes and may
reject any offer, in whole or in part. Each agent will have the right, in its
reasonable discretion, without giving notice to Citicorp, to reject any offer to
purchase Notes received by it, in whole or in part.

      Citicorp will not list the Notes on any securities exchange. Citicorp
gives no assurance that the Notes offered by this prospectus supplement will be
sold or that there will be a secondary market for any of the Notes. Citicorp
may, without notice, withdraw, cancel or modify the offer made by this
prospectus supplement and any pricing supplement.

      Salomon Smith Barney Inc., an affiliate of Citicorp, may use this
prospectus supplement and the prospectus in connection with secondary market
transactions in the Notes. Salomon Smith Barney Inc. may act as principal or
agent in these transactions. These sales will be made at prices related to
prevailing market prices at the time of sale.

      The participation of an affiliate of Citicorp in the offer and sale of the
Notes will comply with the requirements the National Association of Securities
Dealers, Inc. regarding underwriting securities of an affiliate. No Citicorp
affiliate that is a member of the NASD and that is participating in offers and
sales of the Notes will execute a transaction in the Notes in a customer's
discretionary account without the specific written approval of that customer.

      Payment of the purchase price for the Notes must be made in funds
immediately available in New York City.

      Each agent may be deemed to be an "underwriter" under the Securities Act
of 1933 and any discounts or commissions received by that agent from Citicorp
and any profit realized by them on the sale or resale of the Notes may be


                                      S-24
<PAGE>

deemed to be underwriting discounts and commissions. Citicorp has agreed to
indemnify each agent against and contribute toward civil liabilities, including
liabilities under the Securities Act of 1933, that arise from that agent's role
in the sale of the Notes. Citicorp has agreed to reimburse each agent for some
of the expenses incurred in connection with the offering of the Notes.

      In addition to offering Notes through agents as described in this
prospectus supplement, Citicorp may, at the same time that it offers the Notes,
offer other notes. Those notes may include medium-term notes that have terms
substantially similar to the terms of the Notes.

      In connection with the sale of the Notes, agents may engage in:

      o     over-allotments, in which members of the syndicate selling the Notes
            sell more Notes than Citicorp actually sold to the syndicate,
            creating a syndicate short position;

      o     stabilizing transactions, in which purchases and sales of the Notes
            may be made by the members of the selling syndicate at prices that
            do not exceed a specified maximum;

      o     syndicate covering transactions, in which members of the selling
            syndicate purchase Notes in the open market after the distribution
            has been completed in order to cover syndicate short positions; and

      o     penalty bids, by which agents reclaim a selling concession from a
            syndicate member when the Notes originally sold by that syndicate
            member are purchased in a syndicate covering transaction to cover
            syndicate short positions.

      These stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the Notes to be higher than it would
otherwise be. These transactions, if commenced, may be discontinued at any time.

      Each of the agents may engage in transactions with and perform services
for Citicorp or its affiliates in the ordinary course of business.

                                 LEGAL OPINIONS

      Stephanie B. Mudick, as General Counsel - Corporate Law of Citigroup Inc.,
will pass upon the validity of the Notes for Citicorp. Cleary, Gottlieb, Steen &

before you invest.

Neither the Securities and Exchange Commission nor any state securities

<PAGE>

                                    CITICORP

      Citicorp has been a wholly owned subsidiary of Citigroup Inc., a Delaware
holding company formerly known as Travelers Group Inc., since October 8, 1998,
when the merger of Citicorp and Travelers was consummated. Citigroup's
businesses provide a broad range of financial services to consumer and corporate
customers around the world. Citigroup's activities are conducted through Global
Consumer, Global Corporate and Investment Bank, Asset Management and Investment
Activities. Citigroup is not an obligor on any Notes offered by this prospectus.

      Citicorp is a holding company incorporated under the laws of the State of
Delaware on May 8, 1998 to effectuate the merger with Travelers Group and is the
successor to Citicorp, which was incorporated under the laws of the State of
Delaware on December 4, 1967. Citibank is the principal subsidiary of Citicorp.

      Citicorp's principal office is at 399 Park Avenue, New York, New York
10043 and its telephone number is (212) 559-1000. Through its subsidiaries and
affiliates, including Citibank, Citicorp is a global financial services
organization serving the financial needs of individuals, businesses, governments
and financial institutions in the United States and throughout the world.

HOLDING COMPANY

      Citicorp is a legal entity separate and distinct from Citibank and its
other subsidiaries and affiliates. Citicorp is a bank holding company for
purposes of the Bank Holding Company Act of 1956 and is regulated by the Board
of Governors of the Federal Reserve System.

      Citicorp's banking subsidiaries are limited in the extent to which they
may legally extend credit, pay dividends or otherwise supply funds to Citicorp.
For example, a national bank subsidiary of Citicorp must obtain the approval of
the Office of the Comptroller of the Currency to pay total dividends in any
calendar year that exceed its net profits for that year combined with its
retained net profits for the preceding two years. In addition, a national bank
may not pay dividends in excess of its undivided profits. State law may limit
the amount of dividends that Citicorp's state-chartered bank subsidiaries can
pay. Each bank subsidiary must also consider the effect of dividend payments on
applicable risk-based capital and leverage ratio requirements as well as policy
statements of the federal regulatory agencies that indicate that banking
organizations should generally pay dividends out of current operating earnings.

      Citicorp also derives dividends from its non-bank subsidiaries. These
subsidiaries are not affected by regulatory restrictions on their payment of
dividends to Citicorp, except that a savings association subsidiary may be
required to obtain the approval of the Office of Thrift Supervision if it
declares total dividends in any calendar year greater than the amount specified
in that agency's regulations. In addition, there are numerous governmental
requirements and regulations that affect the activities of Citicorp and its bank
and non-bank subsidiaries.

      Under Federal Reserve Board policy, a bank holding company is expected to
act as a source of financial strength to each of its banking subsidiaries and
commit resources to their support. As a result of that policy, Citicorp may be
required to commit resources to its subsidiary banks.

      Because Citicorp is a holding company, its rights and the rights of its
creditors, including the holders of the Notes and its sole stockholder,
Citigroup, to participate in the assets of any of its subsidiaries upon that
subsidiary's liquidation or recapitalization may be adversely affected by prior
claims of that subsidiary's creditors, except to the extent that Citicorp may
itself be a creditor with recognized claims against that subsidiary.

                                 USE OF PROCEEDS

      We intend to use the net proceeds from sales of the Notes for our general
corporate purposes, principally to fund investments in, or extensions of credit
to, our banking and non-banking subsidiaries. Generally, we will not allocate
the proceeds from the sale of an issuance of Notes to any particular purpose,
although we will have determined that funds should be raised at that time in
anticipation of future funding requirements. The precise amount and timing of
our investments in and extensions of credit to our subsidiaries will depend on
their funding requirements and the availability of other funds.

                              RATIOS OF EARNINGS TO
                                  FIXED CHARGES

      The table below shows the ratio of our earnings to our fixed charges for
the three months ended March 31, 1999 and for each calendar year from 1994 to
1998.

                                THREE MONTHS              YEAR ENDED
                               ENDED MARCH 31,            DECEMBER 31,

                                     ----       --------------------------------
Income to Fixed Charges:
  Excluding Interest on Deposits     2.63       2.22   2.59   2.70   2.32   1.77
  Including Interest on Deposits     1.45       1.29   1.43   1.49   1.43   1.31

      For purposes of computing these ratios, income means net income, before
extraordinary items and cumulative effects of accounting changes, plus income
taxes and fixed charges. Fixed charges, excluding interest on deposits means
interest expense (except interest paid on deposits) and that portion of interest
included in rents. Fixed charges, including interest on deposits means all
interest expense and that portion of interest included in rents.

                              DESCRIPTION OF NOTES

      We intend to use this prospectus to offer our unsecured debt securities,
which may be either senior or subordinated. We refer to the senior unsecured
debt securities offered by this prospectus as the Senior Notes, the subordinated
unsecured debt securities offered by this prospectus as the Subordinated Notes
and the Senior Notes and the Subordinated Notes together as the Notes.

      The Senior Notes will be issued under an indenture between Citicorp and
United States Trust Company of New York, as trustee. We refer to this indenture,
as supplemented at any time before the date of this prospectus, as the senior
indenture.

      The Subordinated Notes will be issued under an indenture between Citicorp
and The Chase Manhattan Bank, as trustee. We refer to this indenture as
supplemented at any time before the date of this prospectus as the subordinated
indenture, and, together with the senior indenture, as the indentures.

      This prospectus and the accompanying prospectus supplement describe the
key provisions of the offered notes. To fully understand the terms of the Notes,
you should read this prospectus, the accompanying prospectus supplement and any
applicable pricing supplement, as well as the applicable indenture. You may
obtain a copy of either indenture from Citicorp by calling 212 559-3553.

      Citicorp has other senior and subordinated notes currently outstanding,
and may issue additional senior and subordinated notes after the Notes offered
by this prospectus and the accompanying prospectus supplement have been issued.
We will issue Notes in separate series at various times, based on our funding
needs and market conditions, without limit, as long as the total principal
amount of Notes issued has been authorized by Citicorp's Board of Directors. We
will determine the prices and terms of the Notes when we agree to sell those
Notes. We will provide the terms of each series of Notes in one or more
prospectus supplements to this prospectus.

      The Senior Notes of each series will be unsecured and will rank equally
with all other unsecured and unsubordinated indebtedness of Citicorp. The
Subordinated Notes of each series


                                     - 3 -
<PAGE>

will be unsecured and will rank equally with all other unsecured and
subordinated indebtedness of Citicorp. The Subordinated Notes will rank above
any other subordinated indebtedness that we designate, at its issuance, as
junior to the Subordinated Notes.

      We may use this prospectus to offer series of Notes under documentation
other than and different from the indentures, so long as the material provisions
of the related documentation are described in the applicable prospectus
supplement or pricing supplement and any applicable pricing supplement.

      We will describe the following terms of the Notes of each series in the
related prospectus supplement or pricing supplement and any applicable pricing
supplement:

o     the title of the Notes and whether they are Subordinated Notes or Senior
      Notes;

o     the aggregate principal amount of the Notes;

o     whether the Notes will be issued in global form;

o     the price at which the Notes will be issued;

o     the date on which the Notes will mature;

o     the rate per annum at which the Notes will bear interest, if any, or the
      formula on which the rate will be determined, and the date from which
      interest will accrue;

o     the dates on which interest on the Notes will be payable and the related
      record dates;

o     the person to whom any interest on any Note of the series will be payable,
      if other than the person in whose name that Note is registered at the
      close of business on the record date for interest, and the extent to
      which, or the manner in which, any interest payable on a global Note on an
      interest payment date will be paid;

o     each office or agency where the principal of and any premium and interest
      on the Notes will be payable and where the Notes may be presented for
      registration of transfer or exchange;

o     the periods within which and the prices at which the Notes may, pursuant
      to any optional redemption provisions, be redeemed, in whole or in part,
      and the other terms and provisions of any optional redemption provisions;

o     any obligation of Citicorp to redeem or purchase the Notes or to redeem or
      purchase the Notes at the option of the holder of the Notes, and the terms
      and provisions of that obligation, including the period within which and
      the price at which the Notes may be redeemed or purchased, whether in
      whole or in part, under that obligation;

o     the denominations in which the Notes will be issuable;

o     the currency or currency units of payment of principal of and any premium
      or interest on the Notes, if other than U.S. dollars;

o     any index or formula (which may be based on the value of any currencies,
      commodities, securities or any group or combination of the same) used to
      determine the amount of payments of principal of and any interest or
      premium on the Notes;

o     if applicable, that the terms of the applicable indenture described below
      under "Defeasance and Covenant Defeasance" on page 10 will not apply to
      the series;

o     any additional restrictive covenants included for the benefit of the
      holders of the Notes;

o     any additional Events of Default for the Notes;

o     information describing any book-entry procedures;

o     any other terms of the Notes consistent with the provisions of the
      applicable indenture;


                                     - 4 -
<PAGE>

o     any conversion or exchange provision that permits or requires the Notes to
      be converted into or exchanged for securities issued by Citicorp or
      another issuer; and

o     any special provisions for the payment of additional amounts on the Notes.

      If holders of the Notes can require Citicorp to repurchase the Notes, we
will comply with any applicable provisions of Section 14(e) of the Securities
Exchange Act of 1934 and the related rules and regulations in connection with
that repurchase.

FORM, EXCHANGE, REGISTRATION AND TRANSFER

      We will issue Notes in registered form only. We may issue Notes in global
form. See "Global Notes" on page 6.

      You may exchange your Notes for other Notes of the same series of any
authorized denominations and of the same aggregate principal amount and tenor.
You may not exchange Notes for bearer Notes.

      A holder of a Note may present that Note for registration of transfer
(with the form of transfer properly executed), at the office of the security
registrar or at the office of any transfer agent that Citicorp designates.
Holders of Notes will not be charged a service fee for the exchange or transfer
of their Notes, although holders will be liable for the payment of any taxes and
other governmental charges described in the applicable indenture before the
transfer agent will complete the transfer or exchange. The security registrar or
transfer agent, as the case may be, will effect the transfer or exchange when it
is satisfied with the documents of title and identity of the person making the
request. Citicorp has appointed Citibank as security registrar. Citicorp may at
any time rescind the designation of any transfer agent (other than the security
registrar) or approve a change in the location through which any transfer agent
acts. However, Citicorp will maintain a transfer agent in each place of payment
for a series of Notes. Citicorp may designate additional transfer agents for any
series of Notes.

      If we redeem any series of Notes in part, we need not:

o     issue, register the transfer of or exchange a Note during the period
      beginning at the opening of business 15 days before selection for
      redemption of Notes of the series of which the Note is a part, and ending
      at the close of business on the earliest date on which the notice of
      redemption, as provided in the related indenture, is deemed to have been
      given; or

o     register the transfer of or exchange a Note selected for redemption, in
      whole or in part, except the unredeemed portion of the Note being redeemed
      in part.

PAYMENT AND PAYING AGENTS

      Principal of and any premium or interest on Notes will be payable at the
office of the paying agent or paying agents designated by Citicorp. Citicorp may
pay interest on a Note by check mailed to the address of the person entitled to
that payment at that person's address as it appears in the security register.
Citicorp will pay interest on a Note to the person in whose name that Note was
registered at the close of business on the record date established for the
related interest payment date.

      Citicorp has designated the corporate trust office of Citibank in New York
City as its paying agent for payments on Notes of each series. Citicorp may
designate additional paying agents or rescind the designation of any paying
agent or approve a change in the office through which any paying agent acts.
However, Citicorp will maintain a paying agent in each place of payment for a
series of Notes.

      After notice by publication, all amounts paid by Citicorp to make payments
on the Notes that remain unclaimed two years after the related payment became
due will be repaid to Citicorp. After repayment to Citicorp, the holder of the
Note or its coupon may look only to Citicorp for payment of amounts returned to
Citicorp.

GLOBAL NOTES

      If we issue any Notes of a series in global form, we will describe in the
applicable prospectus supplement the circumstances under which beneficial owners
of interests in that global Note may exchange their interests for Notes of that
series of like principal amount in authorized forms and denominations. We will
pay principal of and any premium or interest on any global Note in the manner
described in the applicable prospectus supplement.

LIMITATIONS ON LIENS ON STOCK OF CITIBANK, N.A.

      So long as any Senior Notes with an original stated maturity of more than
ten years remain outstanding, Citicorp may not permit more than 20% of the
voting stock of Citibank to be used as security for any loan that it receives.
Furthermore, Citicorp may only encumber its Citibank voting stock if the Senior
Notes are secured equally with, or prior to, that indebtedness. This covenant
also applies to subordinated notes issued before November 27, 1992 but does not
apply to the Subordinated Notes that may be offered under this prospectus.

DEFAULTS; EVENTS OF DEFAULT

      The following are Events of Default for any series of Senior Notes:

o     Citicorp's failure to pay principal of or any premium on any Senior Note
      of that series at maturity;

o     Citicorp's failure, uncured after 30 days, to pay interest on any Senior
      Note of that series when due;

o     Citicorp's failure to make any payment toward the purchase of outstanding
      Senior Notes when due;

o     Citicorp's failure, uncured 60 days after written notice, to perform any
      other of its covenants in the senior indenture (other than a covenant
      included in the senior indenture solely for the benefit of series of
      Senior Notes other than that particular series);

o     various events of bankruptcy, insolvency or reorganization of Citicorp or
      Citibank; and

o     any other Event of Default provided for Senior Notes of that series.

      The following are Defaults for any series of Subordinated Notes:

o     Citicorp's failure to pay principal of or any premium on any Subordinated
      Note of that series at maturity;

o     Citicorp's failure, uncured after 30 days, to pay interest on any
      Subordinated Note of that series when due;

o     Citicorp's failure, uncured 60 days after written notice, to perform any
      other of its covenants in the subordinated indenture (other than a
      covenant included in the subordinated indenture solely for the benefit of
      series of Subordinated Notes other than that particular series); and

o     any Event of Default or other Default provided for Subordinated Notes of
      that series.

      The following are Events of Default for any series of Subordinated Notes:

o     various events of bankruptcy, insolvency or reorganization of Citicorp;
      and

o     any other Event of Default provided for Subordinated Notes of that series.

      The holders of a series of Subordinated Notes or the trustee under the
subordinated indenture may declare the acceleration of the payment of principal
or premium, if any, of those Subordinated Notes only if an Event of Default has
occurred and is continuing under the subordinated indenture.

      Generally, if an Event of Default or a Default occurs and is continuing,
the trustee for


                                     - 6 -
<PAGE>

the Notes of the related series must exercise its rights or powers under the
related indenture only if the holders of those Notes offer the trustee
reasonable indemnity. The holders of a majority in aggregate principal amount of
the outstanding Notes of any series may direct the manner of conducting any
proceeding for any remedy available to the related trustee, or exercising any
trust or power conferred on the trustee. This right may only be exercised if the
direction provided by the holders does not conflict with applicable law or the
applicable indenture or have a substantial likelihood of involving the trustee
in personal liability.

      If an Event of Default for Notes of any series occurs and is continuing,
either the related trustee or the holders of at least 25% in aggregate principal
amount of the outstanding Notes of that series may declare the principal of all
outstanding Notes of that series to be due immediately.

      The holders of a majority in aggregate principal amount of outstanding
Notes of that series may rescind that declaration and its consequences if:

o     Citicorp has paid all amounts due (other than those due as a result of the
      related acceleration);

o     Citicorp has remedied, or received the waiver of the holders of those
      Notes of, all Events of Default; and

o     a judgment or decree for payment of the money due has not been obtained.

      A holder of the Notes of any series or any related coupons will have a
right to institute any proceeding under the applicable indenture only if the
following conditions are met:

o     the holder gives to the related trustee written notice of a continuing
      Event of Default or Default;

o     the holders of at least 25% in aggregate principal amount of the
      outstanding Notes of that series make a written request of the trustee to
      institute that proceeding;

o     the holders offer reasonable indemnification to the trustee against the
      costs, liabilities and expenses of instituting that proceeding;

o     the trustee has not received from the holders of a majority in aggregate
      principal amount of the outstanding Notes of that series a direction
      inconsistent with that request; and

o     the trustee has not instituted that proceeding within 60 days after
      receipt of the request and offer of indemnification.

      However, these conditions do not apply to a suit instituted by a holder of
an outstanding Note of that series for enforcement of payment of the principal
of, or any premium or interest on, that Note on or after the date said payment
is due.

      Citicorp will furnish annually to each trustee a statement as to its
performance or fulfillment of covenants, agreements or conditions in the
applicable indenture and the absence of defaults thereunder.

MEETINGS, MODIFICATION AND WAIVER

      Citicorp and the trustee may amend an indenture with the consent of the
holders of a majority in aggregate principal amount of the outstanding Notes of
each series affected by the amendment. However, any amendment that would cause
any of the following events to occur may be made only with the consent of the
holders of each outstanding Note affected by the amendment:

o     change the stated maturity of the principal of, or any installment of
      principal of or interest on, a Note;

o     reduce the principal amount of, or premium or interest on, a Note;

o     change an obligation of Citicorp to pay additional amounts;


                                     - 7 -
<PAGE>

o     reduce the amount of principal of an original issue discount Note payable
      upon acceleration of its maturity;

o     change the currency in which a Note or any premium or interest is payable;

o     impair the right to institute suit for the enforcement of a payment on a
      Note;

o     reduce the percentage in principal amount of outstanding Notes of a
      series, the consent of whose holders is required for modification or
      amendment of the indenture or for waiver of compliance with provisions of
      the indenture or for waiver of defaults;

o     reduce the requirements in the indenture for quorum or voting;

o     change any obligation of Citicorp to maintain an office or agency in the
      places and for the purposes required by the indenture; or

o     modify any of the above provisions.

      Under limited circumstances, Citicorp and the related trustee may amend an
indenture without the consent of any holders of outstanding Notes.

      The holders of a majority in aggregate principal amount of the outstanding
Notes of a series may waive, on behalf of the holders of all the Notes of that
series, compliance by Citicorp with specified restrictive provisions of the
indenture for Notes of that series. The holders of a majority in aggregate
principal amount of the outstanding Notes of a series may, on behalf of all
holders of Notes of that series and any coupons, waive any past default under
the indenture for Notes of that series. However, the consent of the holders of
all outstanding Notes of a series is required to waive:

o     a past default in the making of timely payments on the Notes of that
      series; or
o     the breach of a covenant or provision of the indenture that cannot be
      modified or amended without the consent of the holders of each outstanding
      Note of that series.

      Each indenture provides that the following principles will be used in
determining whether the holders of the requisite principal amount of the
outstanding Notes have given their request, demand, authorization, direction,
notice, consent or waiver or are present at a meeting of holders of Notes for
quorum purposes:

o     the principal amount of an original issue discount Note that will be
      deemed to be outstanding will be the amount of the principal that would be
      due and payable as of the date of determination upon acceleration of its
      maturity; and

o     the principal amount of a Note denominated in a foreign currency or
      currency unit will be the U.S. dollar equivalent, determined on the date
      of original issuance of the Note, of the principal amount of the Note or,
      in the case of an original issue discount Note of the amount determined as
      provided in the clause above.

      The trustee may call a meeting of the holders of Notes of a series at any
time. The trustee must call a meeting upon the request of Citicorp or the
holders of at least 10% in aggregate principal amount of the outstanding Notes
of a series. Meetings will be called after notice is given to the holders of the
Notes in accordance with "Notices" below on page 9.

      Except for a consent that must be given by the holders of each outstanding
Note affected, a resolution presented at a meeting at which a quorum is present
may be adopted by the affirmative vote of the holders of a majority in aggregate
principal amount of the outstanding Notes of that series. However, a resolution
as to an action that may be taken by the holders of a specified percentage in
aggregate principal amount of outstanding Notes of a series may be adopted at a
meeting at which a quorum is present only by the affirmative vote of the holders
of that specified percentage in aggregate principal amount of Notes.


                                     - 8 -
<PAGE>

      A resolution passed or decision taken at a meeting of holders of Notes of
a series held in accordance with the indenture will bind all holders of Notes of
that series and any related coupons. The quorum at a meeting called to adopt a
resolution, and at an adjourned meeting, will be persons holding or representing
a majority in aggregate principal amount of the outstanding Notes of a series.
However, if an action may be taken by the holders of a specified percentage in
aggregate principal amount of the outstanding Notes of a series, the persons
holding or representing that specified percentage in aggregate principal amount
of Notes of that series will constitute a quorum.

CONSOLIDATION, MERGER AND SALE OF ASSETS

      Citicorp may, without the consent of the holders of any of the outstanding
Notes of a series, consolidate with, merge into or transfer its assets
substantially as an entirety to any corporation organized under the laws of any
domestic or foreign jurisdiction, if the following conditions are met:

o     the successor corporation must assume Citicorp's obligations on the Notes
      of each series and under the applicable indenture;

o     for the Senior Notes, after giving effect to the merger or transfer, no
      Event of Default and no event that, after notice or lapse of time, or
      both, would become an Event of Default has occurred and is continuing; and

o     for the Subordinated Notes, after giving effect to the merger or transfer,
      no Default and no event that, after notice or lapse of time, or both,
      would become a Default, has occurred and is continuing.

      The covenants in the applicable indenture will not necessarily afford
holders of either the Senior Notes or the Subordinated Notes protection in the
event of a decline in credit quality resulting from a takeover, recapitalization
or similar restructuring.

NOTICES

      Notices to holders of Notes will be given by mail sent to the addresses of
the holders as they appear in the security register.

TITLE

      Citicorp, the related trustee and any agent of Citicorp or that trustee
may treat the registered owner of a Note or coupon as the absolute owner of the
Note--even if the registered owner of that Note has given notice to the
contrary--for all purposes.

REPLACEMENT OF NOTES AND COUPONS

      Citicorp will replace at the expense of the holder any mutilated Note, or
a Note with a mutilated coupon, upon surrender of that Note to the trustee.
Citicorp will replace at the expense of the holder any Notes or coupons that are
destroyed, lost or stolen upon delivery to the trustee of evidence satisfactory
to Citicorp and the trustee of the destruction, loss or theft of those Notes or
coupons. Citicorp will replace a coupon that is destroyed, lost or stolen, by
issuance of a new Note in exchange for the Note to which that coupon appertains.
Citicorp and the trustee may require an indemnity satisfactory to the trustee
and Citicorp at the expense of the holder of the Note or coupon before a
replacement Note will be issued.

DEFEASANCE AND COVENANT DEFEASANCE

            Citicorp may be released from:

      o     some or all of its obligations on a series of Notes, a defeasance;
            and/or

      o     its obligations described above on page 6 under "Limitations on
            Liens on Stock of Citibank, N.A.," a covenant defeasance.

      A release from these obligations will occur when Citicorp deposits with
the trustee money and/or U.S. government obligations that, through the payment
of principal and interest, will provide enough money, without


                                     - 9 -
<PAGE>

reinvestment, to make all payments on the Notes to maturity or redemption, as
the case may be, and any mandatory payments required to be made for the purchase
of outstanding Notes.

      Before it causes a defeasance or covenant defeasance, Citicorp must
deliver to the trustee an opinion of counsel that the holders of the Notes:

o     will not recognize income, gain or loss for United States federal income
      tax purposes as a result of the defeasance or covenant defeasance; and

o     will bear the same United States federal income tax consequences as would
      have been the case if the defeasance or covenant defeasance had not
      occurred.

      Citicorp may cause the defeasance of the Notes of a series even if
Citicorp has caused those Notes' covenant defeasance. Following a defeasance,
payments on the Notes may not be accelerated because of an Event of Default or a
Default. Following a covenant defeasance, payment of Senior Notes or
subordinated notes issued before November 27, 1992 may not be accelerated.
However, if an acceleration were to occur, the realizable value at the
acceleration date of the money and U.S. government obligations deposited with
the trustee for the defeasance could be less than the principal and interest
then due on the Notes because the required deposit is based on scheduled cash
flows rather than market value, which will vary depending on interest rates and
other factors that affect the prices of marketable securities.

SUBORDINATION

      The Subordinated Notes will be subordinate and junior in right of payment,
to all Senior Indebtedness (as defined below) of Citicorp. If Citicorp defaults
in the payment of principal of or premium or interest on Senior Indebtedness
when due, then, until that default is cured, waived or ceases to exist, no
payment will be made for any purpose on the Subordinated Notes.

      If any of the following events occurs, all Senior Indebtedness (including
interest on Senior Indebtedness accruing after the commencement of any
proceeding referred to below) will be paid in full before any payment or
distribution under the Subordinated Notes will be made:

o     an insolvency, bankruptcy, receivership, liquidation, reorganization,
      readjustment, composition or other similar proceeding relating to
      Citicorp, its creditors or its property;

o     a proceeding for the liquidation, dissolution or other winding-up of
      Citicorp, voluntary or involuntary, whether or not involving insolvency or
      bankruptcy proceedings;

o     an assignment by Citicorp for the benefit of creditors; or

o     any other marshaling of the assets of Citicorp.

      In any of those events, a payment that would otherwise have been made on
the Subordinated Notes instead will be made to the holders of Senior
Indebtedness in accordance with the existing priorities among those holders,
until all Senior Indebtedness has been paid in full. If a payment under the
Subordinated Notes is received by any holder of Subordinated Notes before all
the Senior Indebtedness has been paid in full, that payment will be received in
trust for the benefit of, the holders of the outstanding Senior Indebtedness in
accordance with the existing priorities among those holders to the extent
necessary to pay all Senior Indebtedness in full.

      This subordination of the Subordinated Notes does not apply to the
distribution of securities of Citicorp or any other corporation provided for by
a plan of reorganization or readjustment if that distribution is subordinate to
the payment of all outstanding Senior Indebtedness, and to any other securities
issued under that plan of reorganization or readjustment.


                                     - 10 -
<PAGE>

      Senior Indebtedness means any present or future obligation of Citicorp to
its creditors, other than:

o     notes issued under the subordinated indenture (including Subordinated
      Notes);

o     other unsecured and subordinated indebtedness of Citicorp, and all other
      unsecured and subordinated guarantees by Citicorp of indebtedness of other
      persons;

o     obligations incurred or assumed by Citicorp in the ordinary course of
      business and all obligations of Citicorp in respect of any guarantees of
      the obligations of its subsidiaries (excluding traveler's checks and other
      unsubordinated financial instruments); and

o     other obligations that specifically state that they do not constitute
      Senior Indebtedness.

      Neither indenture limits the amount of additional Senior Indebtedness that
Citicorp may issue.

      As of November 27, 1992, Citicorp and the trustee for the Subordinated
Notes amended the subordinated indenture in response to an interpretation of the
staff of the Board of Governors of the Federal Reserve System concerning the
capital treatment of subordinated debt. The amendment removed a restrictive
covenant relating to liens permitted on the stock of Citibank and narrowed the
definition of Event of Default to provide that the appointment of a receiver or
trustee for Citicorp or substantially all (rather than a substantial part) of
its property is an Event of Default. The amendment does not apply to any series
of subordinated notes issued prior to November 27, 1992. Therefore, holders of
subordinated notes issued before November 27, 1992 could demand immediate
payment of their notes upon the occurrence of various events of bankruptcy or
insolvency that would not entitle the holders of Subordinated Notes offered by
this prospectus to demand immediate payment of these Notes.

GOVERNING LAW

      The laws of the State of New York will govern and be used to construe each
indenture, the Notes and any coupons.

THE TRUSTEES

      The principal corporate trust office of United States Trust Company of New
York, the trustee under the senior indenture, is located at 114 West 47th
Street, New York, New York 10036. United States Trust Company of New York also
serves as a trustee under other Citicorp indentures under which unsecured debt
securities are currently outstanding.

      The principal corporate trust office of The Chase Manhattan Bank, the
trustee under the subordinated indenture, is located at 450 West 33rd Street,
New York, New York 10001. The Chase Manhattan Bank also serves as a trustee
under other indentures under which subordinated unsecured debt securities issued
or guaranteed by Citicorp are currently outstanding.

      Citicorp or its affiliates maintain accounts and other banking
relationships with the trustees and their respective affiliates.

                             FOREIGN CURRENCY RISKS

      Citicorp may offer Notes denominated in a foreign currency or currency
unit. Persons who are not residents of the United States should consult their
own legal advisors regarding matters that may affect their purchase or holding
of those Notes or the receipt of payments of principal of and premium and
interest on those Notes.

EXCHANGE RATES AND EXCHANGE CONTROLS

      An investment in Notes denominated in a foreign currency entails
significant risks and is not an appropriate investment for an investor who is
not experienced in foreign currency transactions. If you are considering
investing in Notes denominated in a foreign currency, you


                                     - 11 -
<PAGE>

should consult your own financial and legal advisors as to the risks involved in
this type of investment.

      Investments in Notes denominated in a foreign currency involve risks that
are not associated with similar investments in U.S. dollar denominated Notes.
These risks include the possibility that the rate of exchange between the U.S.
dollar and the relevant foreign currency may change significantly and the
possibility that either the United States or foreign governments may impose or
modify foreign exchange controls. Citicorp generally has no control over the
economic and political events likely to affect foreign exchange rates or foreign
exchange controls or other similar governmental actions.

      In recent years, the rates of exchange between the U.S. dollar and some
foreign currencies have been highly volatile, and they may be highly volatile in
the future. Fluctuations in any particular exchange rate that have occurred in
the past, however, do not necessarily indicate how fluctuations in the rate may
occur during the term of any Notes denominated in a foreign currency. Changes in
the exchange rate of the relevant foreign currency against the U.S. dollar would
generally result in changes in the U.S. dollar-equivalent market value of the
security.

                                  ERISA MATTERS

      By virtue of Citicorp's affiliation with certain of its subsidiaries and
certain subsidiaries of Citigroup, including insurance company subsidiaries and
Salomon Smith Barney Inc., that provide services to many employee benefit plans,
including investment advisory and asset management services, Citicorp, Citigroup
and any direct or indirect subsidiary of either of them may each be considered a
"party in interest" within the meaning of the Employee Retirement Income
Security Act of 1974 and a "disqualified person" under corresponding provisions
of the Internal Revenue Code of 1986, relating to many employee benefit plans.
"Prohibited transactions" within the meaning of ERISA and the Code may result if
any offered Notes are acquired by an employee benefit plan relating to which
Citicorp, Citigroup or any direct or indirect subsidiary of either of them is a
party in interest, unless such offered Notes are acquired pursuant to an
applicable exemption. Any employee benefit plan or other entity subject to such
provisions of ERISA or the Code proposing to acquire the offered Notes should
consult with its legal counsel.

                              PLAN OF DISTRIBUTION

      Citicorp may offer and sell the Notes in any of three ways:

o     directly to one or more purchasers;

o     through agents designated from time to time; or

o     through underwriters.

      Any underwriter or agent that offers the Notes may be an affiliate of
Citicorp, and offers and sales of Notes may include secondary market
transactions by affiliates of Citicorp. These affiliates may act as principal or
agent in these sales. These sales will be made at prices based on market prices
at the time of sale.

      Citicorp will set forth in the applicable prospectus supplement or pricing
supplement:

o     the terms of each offering, including the name or names of any
      underwriters or agents;

o     the managing underwriters of any underwriting syndicate;

o     the public offering or purchase price;

o     the net proceeds to Citicorp from the sale;

o     any underwriting discounts and other items constituting underwriters'
      compensation, any discounts and commissions allowed or paid to dealers,
      any commissions allowed or paid to agents; and


                                     - 12 -
<PAGE>

o     the securities exchanges, if any, on which the Notes will be listed.

      Dealer trading may take place in the Notes, including Notes not listed on
any securities exchange. Direct sales may be made by Citicorp on a national
securities exchange or otherwise. If Citicorp, directly or through agents,
solicits offers to purchase Notes, Citicorp reserves the sole right to accept
and, together with its agents, to reject in whole or in part any proposed
purchase of Notes.

      Citicorp may change any initial public offering price and any discounts or
concessions allowed or reallowed or paid to dealers. If indicated in the
applicable prospectus supplement, Citicorp will authorize underwriters or agents
to solicit offers by institutional investors to purchase Notes from Citicorp
under delayed delivery contracts that provide for payment and delivery at a
future date.

      Any underwriter or agent participating in the distribution of the Notes
may be deemed to be an underwriter of those Notes under the Securities Act of
1933. Any discounts or commissions received by them and any profit realized by
them on the sale or resale of the Notes may be deemed to be underwriting
discounts and commissions. Citicorp has agreed to indemnify each underwriter,
agent and their controlling persons against and contribute toward its civil
liabilities, including liabilities under the Securities Act of 1933, that arise
from that agent's role in the sale of the Notes.

      The participation of an affiliate of Citicorp in the offer and sale of the
Notes will comply with the requirements of National Association of Securities
Dealers, Inc. regarding underwriting securities of an affiliate. No Citicorp
affiliate that is a member of the NASD and that is participating in offers and
sales of the Notes will execute a transaction in the Notes in a customer's
discretionary account without the specific written approval of that customer.

      Citicorp is not making an offer of the Notes in any jurisdiction where the
offer is not permitted.

      Underwriters and agents participating in the distribution of the Notes,
and their controlling persons, may engage in transactions with and perform
services for Citicorp or its affiliates in the ordinary course of business.

                                 LEGAL OPINIONS

      Stephanie B. Mudick, as General Counsel - Corporate Law of Citigroup Inc.,
will pass upon the validity of the Notes for Citicorp. Cleary, Gottlieb, Steen &
Hamilton, One Liberty Plaza, New York, New York 10006, will pass upon the
validity of the Notes for the agents. Ms. Mudick owns or has the right to
acquire a number of shares of common stock of Citigroup equal to less than 0.01%
of the outstanding common stock of Citigroup.
