                                SUMMARY OF TERMS

    Because this is a summary it does not contain all the information you may
need to make an informed investment decision. You should read the entire
prospectus supplement and prospectus before you purchase any of these Class B
notes.

    There is a glossary beginning on page 111 of the prospectus where you will
find the definitions of some terms used in this prospectus supplement.

Securities Offered........  $350,000,000 7.05% Class 2000-B1 notes of September
                            2005 (legal maturity date September 2007).

                            These Class B notes are part of a multiple issuance
                            series of notes called the Citiseries. The
                            Citiseries consists of Class A notes, Class B notes
                            and Class C notes. These Class B notes are a
                            subclass of Class B notes of the Citiseries.

                            These Class B notes are issued by, and are
                            obligations of, Citibank Credit Card Issuance
                            Trust. The issuer expects to issue other classes
                            and subclasses of notes of the Citiseries with
                            different interest rates, payment dates, legal
                            maturity dates and other characteristics. See "The
                            Notes--Issuances of New Series, Classes and
                            Subclasses of Notes" in the prospectus.

Multiple Issuance
 Series...................  A multiple issuance series is a series of notes
                            consisting of three classes: Class A, Class B and
                            Class C. Each class may consist of multiple
                            subclasses. Notes of any subclass can be issued on
                            any date so long as there are enough outstanding
                            subordinated notes to provide the necessary
                            subordination protection for outstanding and newly
                            issued senior notes. The expected principal payment
                            dates and legal maturity dates of the senior and
                            subordinated classes of a multiple issuance series
                            may be different, and subordinated notes may have
                            expected principal payment dates and legal maturity
                            dates earlier than some or all senior notes of the
                            same series. Subordinated notes will generally not
                            be paid before their legal maturity date, unless,
                            after payment, the remaining subordinated notes
                            provide the required amount of subordination
                            protection for the senior notes of that series.

                            All of the subordinated notes of a multiple
                            issuance series provide subordination protection to
                            all of the senior notes of the same series,
                            regardless of whether the subordinated

                                      S-3
<PAGE>

                            notes are issued before, at the same time as, or
                            after the senior notes of that series.

Interest..................  These Class B notes will accrue interest at a rate
                            of 7.05% per annum.

                            Interest on these Class B notes will begin to
                            accrue on September 26, 2000 and will be calculated
                            on the basis of a 360-day year of twelve 30-day
                            months.

                            The issuer will make interest payments on these
                            Class B notes on the 15th day of each March and
                            September, beginning in March 2001. Interest
                            payments due on a day that is not a business day in
                            New York, South Dakota and Nevada, will be made on
                            the following business day.

                            The payment of accrued interest on a class of notes
                            of the Citiseries is not senior to or subordinated
                            to payment of interest on any other class of notes
                            of this series.

Principal.................
                            The issuer expects to pay the stated principal
                            amount of these Class B notes in one payment on
                            September 15, 2005, which is the expected principal
                            payment date, and is obligated to do so if funds
                            are available for that purpose and not required for
                            subordination. However, if the stated principal
                            amount of these Class B notes is not paid in full
                            on its expected principal payment date, noteholders
                            will not have any remedies against the issuer until
                            September 17, 2007, the legal maturity date of
                            these Class B notes.

                            If the stated principal amount of these Class B
                            notes is not paid in full on the expected principal
                            payment date, then, subject to the principal
                            payment rules described below under "Subordination;
                            Credit Enhancement," principal and interest
                            payments on those notes will be made monthly until
                            they are paid in full or the legal maturity date
                            occurs, whichever is earlier. However, if the
                            nominal liquidation amount of these Class B notes
                            has been reduced, the amount of principal
                            collections and finance charge collections
                            available to pay principal of and interest on these
                            Class B notes will be reduced. The nominal
                            liquidation amount of a class of notes corresponds
                            to the portion of the invested amount of the
                            collateral certificate that is allocable to support
                            that class of notes.

                            The initial nominal liquidation amount of these
                            Class B notes is $350,000,000. If this amount is
                            reduced by reallocations of principal of these
                            Class B notes to pay interest on a senior class, or
                            as a result of charge-offs to the principal
                            receivables in the master trust, and not reimbursed
                            as described in the prospectus, not all of the
                            principal of these Class B notes will be repaid.
                            For a more detailed discussion of nominal
                            liquidation amount, see "The Notes--Stated
                            Principal Amount, Outstanding Dollar Principal
                            Amount and Nominal Liquidation Amount of Notes" in
                            the prospectus.

                            Principal of these Class B notes may be paid
                            earlier than its expected principal payment date if
                            an early redemption event or an event of default
                            occurs with respect to these notes. See "Covenants,
                            Events of Default and Early Redemption Events--
                            Early Redemption Events" and "--Events of Default"
                            in the prospectus.

Subordination; Credit
  Enhancement.............  No payment of principal will be made on any Class B
                            note in the Citiseries unless, following the
                            payment, the remaining available subordinated
                            amount of Class B notes in this series is at least
                            equal to the required subordinated amount for the
                            outstanding Class A notes in this series.
                            Similarly, no payment of principal will be made on
                            any Class C note in the Citiseries unless,
                            following the payment, the remaining available
                            subordinated amount of Class C notes in this series
                            is at least equal to the required subordinated
                            amounts for the outstanding Class A notes and Class
                            B notes in this series. However, there are some
                            exceptions to this rule. See "The Notes--
                            Subordination of Principal" and "Deposit and
                            Application of Funds--Limit on Repayments of
                            Subordinated Classes of Multiple Issuance Series"
                            in the prospectus.

                            The principal of these Class B notes may be applied
                            to provide subordination protection to the Class A
                            notes of the Citiseries. The maximum amount of
                            principal of Class C notes in the Citiseries that
                            may be applied to provide subordination protection
                            to these Class B notes is $466,666,655. This amount
                            of principal of Class C notes may also be applied
                            to provide subordination protection to the Class A
                            notes of the Citiseries.

                            The issuer may at any time change the amount of
                            subordination required or available for any class
                            of notes

                            of the Citiseries, including these Class B notes,
                            or the method of computing the amounts of that
                            subordination without the consent of any
                            noteholders so long as the issuer has received
                            confirmation from the rating agencies that have
                            rated any outstanding notes of the Citiseries that
                            the change will not result in the rating assigned
                            to any outstanding notes of the Citiseries to be
                            withdrawn or reduced, and the issuer has received
                            the tax opinions described in "The Notes--Required
                            Subordinated Amount" in the prospectus.

                            See "Deposit and Application of Funds" in the
                            prospectus for a description of the subordination
                            protection of these Class B notes.

The Interest Rate Swap....  In order to manage its interest rate risk, the
                            issuer intends to enter into an interest rate swap
                            with a swap counterparty that is a financial
                            institution with a rating of at least "AA." Under
                            the interest rate swap, the issuer will pay
                            interest monthly to the swap counterparty on a
                            notional amount based on a floating rate of
                            interest equal to one-month LIBOR plus a margin not
                            greater than 0.36% per annum. The swap counterparty
                            will pay interest monthly to the issuer on a
                            notional amount based on the rate of interest
                            applicable to these Class B Notes. Net swap
                            payments will be paid out of funds available in the
                            interest funding subaccount for these Class B
                            notes. Net swap receipts will be deposited into the
                            interest funding subaccount for these Class B notes
                            and will be available to pay interest on these
                            Class B notes.

                            Neither a ratings downgrade or a default by the
                            swap counterparty will constitute an early
                            redemption event or an event of default with
                            respect to these Class B Notes, nor affect the
                            obligation of the issuer to pay interest on and
                            principal of these Class B Notes.

Optional Redemption by
 the Issuer...............
                            The issuer has the right, but not the obligation,
                            to redeem these Class B notes in whole but not in
                            part on any day on or after the day on which the
                            aggregate nominal liquidation amount of these Class
                            B notes is reduced to less than 5% of its initial
                            dollar principal amount. This repurchase option is
                            referred to as a clean-up call. However, the issuer
                            will not redeem subordinated notes if

                                      S-6
<PAGE>

                            those notes are required to provide subordination
                            protection for senior classes of notes of the
                            Citiseries.

                            If the issuer elects to redeem these Class B notes,
                            it will notify the registered holders of the
                            redemption at least 30 days prior to the redemption
                            date. The redemption price of a note so redeemed
                            will equal 100% of the outstanding dollar principal
                            amount of that note, plus accrued but unpaid
                            interest on the note to but excluding the date of
                            redemption.

                            If the issuer is unable to pay the redemption price
                            in full on the redemption date, monthly payments on
                            these Class B notes will thereafter be made,
                            subject to the principal payment rules described
                            above under "Subordination; Credit Enhancement,"
                            until the principal amount of those notes, plus all
                            accrued and unpaid interest, is paid in full or the
                            legal maturity date occurs, whichever is earlier.
                            Any funds in the principal funding account and
                            interest funding account for these Class B notes
                            will be applied to make the principal and interest
                            payments on these notes on the redemption date.

Security for the Notes....  These Class B notes are secured by a shared
                            security interest in the collateral certificate and
                            the collection account, but are entitled to the
                            benefits of only that portion of those assets
                            allocated to them under the indenture. These Class
                            B notes are also secured by a security interest in
                            the applicable principal funding subaccount, the
                            applicable interest funding subaccount and the
                            interest rate swap. See "Sources of Funds to Pay
                            the Notes--The Collateral Certificate" and "--The
                            Trust Accounts" in the prospectus.

                            .  payments received from the swap counterparty
                               under the interest rate swap; and

                            .  funds in the applicable trust accounts for these
                               Class B notes.

                            Class B noteholders will have no recourse to any
                            other assets of the issuer or any other person or
                            entity for the payment of principal of or interest
                            on these Class B notes.

Master Trust Assets and
 Receivables..............
                            The collateral certificate, which is the issuer's
                            primary source of funds for the payment of
                            principal of and interest on these Class B notes,
                            is an investor certificate issued by Citibank
                            Credit Card Master Trust I. The collateral
                            certificate represent an undivided interest in the
                            assets of the master trust. The master trust assets
                            include credit card receivables from selected
                            MasterCard and VISA revolving credit card accounts
                            that meet the eligibility criteria for inclusion in
                            the master trust. These eligibility criteria are
                            discussed in the prospectus under "The Master
                            Trust--Master Trust Assets."

                            The credit card receivables in the master trust
                            consist of principal receivables and finance charge
                            receivables. Principal receivables include amounts
                            charged by cardholders for merchandise and services
                            and amounts advanced to cardholders as cash
                            advances. Finance charge receivables include
                            periodic finance charges, annual membership fees,
                            cash advance fees, late charges and certain other
                            fees billed to cardholders.

                            The aggregate amount of credit card receivables in
                            the master trust as of June 24, 2000 was
                            $49,933,632,318, of which $49,303,959,429 were
                            principal receivables and $629,672,889 were finance
                            charge receivables. See "The Master Trust
                            Receivables and Accounts" in Annex I of this
                            prospectus supplement for more detailed financial
                            information on the receivables and the accounts.

The Citiseries............  These Class B notes will be the third subclass of
                            notes issued by the issuer in the Citiseries.

                            As of the issuance date of these Class B notes, the
                            aggregate outstanding dollar principal amount of
                            notes in the Citiseries will be $1,300,000,000,
                            including these Class B notes and other subclasses
                            of notes of the Citiseries issued on that day,
                            consisting of:

                            Class B notes  $500,000,000
                            Class C notes  $800,000,000

Participation with Other
 Classes of Notes.........
                            Each class of notes of the Citiseries will be
                            included in "Group 1." In addition to the
                            Citiseries, the issuer may issue other series of
                            notes that are included in Group 1. As of the date
                            of this prospectus supplement, the Citiseries is
                            the only series of notes issued by the issuer.

                            Collections of finance charge receivables allocable
                            to each class of notes in Group 1 will be
                            aggregated and shared by each class of notes in
                            Group 1 pro rata based on the applicable interest
                            rate of each class. See "Deposit and Application of
                            Funds--Allocation to Interest Funding Subaccounts"
                            in the Prospectus. Under this system, classes of
                            notes in Group 1 with high interest rates take a
                            larger proportion of the collections of finance
                            charge receivables allocated to Group 1 than
                            classes of notes with low interest rates.
                            Consequently, the issuance of later classes of
                            notes with high interest rates can have the effect
                            of reducing the finance charge collections
                            available to pay interest on your notes, or
                            available to reimburse reductions in the nominal
                            liquidation amount of your notes.

Stock Exchange Listing....  The issuer will apply to list these Class B notes
                            on the Luxembourg Stock Exchange. The issuer cannot
                            guarantee that the application for the listing will
                            be accepted. You should consult with Banque
                            Internationale a Luxembourg, the Luxembourg listing
                            agent for these Class B notes, 69, route d'Esch, L-
                            2953 Luxembourg, phone number (352) 4590-1, to
                            determine whether these Class B notes have been
                            listed on the Luxembourg Stock Exchange.

Ratings...................
                            The issuer will issue these Class B notes only if
                            they are rated at least "A" or its equivalent by at
                            least one nationally recognized rating agency. See
                            "Risk Factors--If the ratings of the notes are
                            lowered or withdrawn, their market value could
                            decrease" in the prospectus.

</TABLE>

    The several underwriters have agreed, subject to the terms and conditions
of the underwriting agreement, to purchase all $350,000,000 aggregate principal
amount of these Class B notes if any of these Class B notes are purchased.

    The underwriters have advised the issuer that the several underwriters
propose initially to offer these Class B notes to the public at the public
offering price set forth on the cover page of this prospectus supplement, and
to certain dealers at that public offering price less a concession not in
excess of 0.200% of the principal amount of these Class B notes. The
underwriters may allow, and those dealers may reallow to other dealers, a
concession not in excess of 0.125% of the principal amount.

    After the public offering, the public offering price and other selling
terms may be changed by the underwriters.

    Each underwriter of these Class B notes has agreed that:

      Financial Services Act 1986 with respect to anything done by it in
      relation to these Class B notes in, from or otherwise involving the
      United Kingdom;

  .   it has only issued, distributed or passed on and will only issue,
      distribute or pass on in the United Kingdom any document received by
      it in connection with the issue of these Class B notes to a person who
      is of a kind described in Article 11(3) of the Financial Services Act
      1986 (Investment Advertisements) (Exemptions) Order 1996 or is a
      person to whom such document may otherwise lawfully be issued,
      distributed or passed on;

  .   if it is an authorized person under Chapter III of Part I of the
      Financial Services Act 1986, it has only promoted and will only
      promote (as that term is defined in Regulation 1.02(2) of the
      Financial Services (Promotion of Unregulated Schemes) Regulations
      1991) to any person in the United Kingdom the scheme described in this
      prospectus supplement and the prospectus if that person is a kind
      described either in Section 76(2) of the Financial Services Act 1986
      or in Regulation 1.04 of the Financial Services (Promotion of
      Unregulated Schemes) Regulations 1991; and

      Services Act 1986 (Investment Advertisements) (Exemptions) Order 1986.

    In connection with the sale of these Class B notes, the underwriters may
engage in:

  .   over-allotments, in which members of the syndicate selling these Class
      B notes sell more notes than the issuer actually sold to the
      syndicate, creating a syndicate short position;

  .   stabilizing transactions, in which purchases and sales of these Class
      B notes may be made by the members of the selling syndicate at prices
      that do not exceed a specified maximum;

  .   syndicate covering transactions, in which members of the selling
      syndicate purchase these Class B notes in the open market after the
      distribution has been completed in order to cover syndicate short
      positions; and

  .   penalty bids, by which underwriters reclaim a selling concession from
      a syndicate member when any of these Class B 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 these Class B notes to be higher than it would
otherwise be. These transactions, if commenced, may be discontinued at any
time.

    The issuer, Citibank (South Dakota) and Citibank (Nevada) will, jointly and
severally, indemnify the underwriters against certain liabilities, including
liabilities under applicable securities laws, or contribute to payments the
underwriters may be required to make in respect of those liabilities. The
issuer's obligation to indemnify the underwriters will be limited to finance
charge collections from the collateral certificate received by the issuer after
making all required payments and required deposits under the indenture.

Dakota) and Citibank (Nevada).

related to market-making transactions in these Class B notes. These affiliates
may act as principal or agent in these market-making transactions. Market-
making sales will be made at prices related to prevailing market prices at the
time of sale.

amount of those notes. The issuer will receive this amount net of the

on the credit card accounts for each of the periods shown. Losses consist of
write-offs of principal receivables. These losses are presented below on a cash
basis. If accrued finance charge receivables that have been written off were
included in losses, Net Losses would be higher as an absolute number and as a
percentage of the average of principal and finance charge receivables
outstanding during the periods indicated. Average Principal Receivables
Outstanding is the average of principal receivables outstanding during the
periods indicated. The percentage reflected for the six months ended June 30,
2000 is an annualized number. We cannot provide any assurance that the loss
experience for the receivables in the future will be similar to the historical
experience set forth below.

    Net losses as a percentage of gross charge-offs for the first six months of
2000 were 87.02% and for each of the years ended December 31, 1999, 1998 and
1997 were 89.80%, 91.56% and 92.49%, respectively. Gross charge-offs are
charge-offs before recoveries and do not include the amount of any reductions
in Average Principal Receivables Outstanding due to fraud, returned goods,
customer disputes or certain other miscellaneous write-offs.

    The following table sets forth the delinquency experience for cardholder
payments on the credit card accounts for each of the periods shown. The
Delinquent Amount includes both principal receivables and finance charge
receivables. The percentages are the result of dividing the Delinquent Amount
by the average of principal and finance charge receivables outstanding during
the periods indicated. We cannot provide any assurance that the delinquency
experience for the receivables in the future will be similar to the historical
experience set forth below.

Revenue Experience

    The revenues for the credit card accounts from finance charges, fees paid
by cardholders and interchange for the six months ended June 30, 2000 and for
each year of the three-year period ended December 31, 1999 are set forth in the
following table.

    The revenue experience in this table is presented on a cash basis before
deduction for charge-offs. Average Revenue Yield is the result of dividing
Finance Charges and Fees Paid by Average Principal Receivables Outstanding
during the periods indicated. The percentage for the six months ended June 30,
2000 is an annualized number. Revenues from finance charges, fees and
interchange will be affected by numerous factors, including the periodic
finance charge on the credit card receivables, the amount of any annual
membership fee, other fees paid by cardholders, the percentage of cardholders
who pay off their balances in full each month and do not incur periodic finance
charges on purchases, the percentage of credit card accounts bearing finance
charges at promotional rates and changes in the level of delinquencies on the
receivables.

</TABLE>

    The revenues from periodic finance charges and fees--other than annual
fees--depend in part upon the collective preference of cardholders to use their
credit cards as revolving debt instruments for purchases and cash advances and
to pay account balances over several months--as opposed to convenience use,
where cardholders pay off their entire balance each month, thereby avoiding
periodic finance charges on their purchases--and upon other card-related
services for which the cardholder pays a fee. Fees for these other services
will be treated for purposes of the pooling and servicing agreement as
principal receivables rather than finance charge receivables; however, the
Banks may specify that they will treat these fees as finance charge
receivables. Revenues from periodic finance charges and fees also depend on the
types of charges and fees assessed on the credit card accounts. Accordingly,

                                      I-2
<PAGE>

revenues will be affected by future changes in the types of charges and fees
assessed on the accounts and in the types of additional accounts added from
time to time. These revenues could be adversely affected by future changes in
fees and charges assessed by Citibank (South Dakota) and other factors.

Cardholder Monthly Payment Rates

    Monthly payment on the credit card receivables may vary because, among
other things, a cardholder may fail to make a required payment, may only make
the minimum required payment or may pay the entire outstanding balance. Monthly
payment rates on the receivables may also vary due to seasonal purchasing and
payment habits of cardholders. The following table sets forth the highest and
lowest cardholder monthly payment rates for the credit card accounts during any
month in the periods shown and the average of the cardholder monthly payment
rates for all months during the periods shown, in each case calculated as a
percentage of the total beginning account balances for that month. Monthly
payment rates include amounts that would be deemed payments of principal
receivables and finance charge receivables with respect to the accounts. In
addition, the amount of outstanding receivables and the rates of payments,
delinquencies, charge-offs and new borrowings on the accounts depend on a
variety of factors including seasonal variations, the availability of other
sources of credit, general economic conditions, tax laws, consumer spending and
borrowing patterns and the terms of the accounts, which Citibank (South Dakota)
may change.

Interchange

    Creditors participating in the MasterCard International and VISA
associations receive interchange as partial compensation for taking credit
risk, absorbing fraud losses and funding receivables for a limited period
before initial billing. Under the MasterCard International and VISA systems, a
portion of this interchange in connection with cardholder charges for
merchandise and services is passed from banks which clear the transactions for
merchants to credit card-issuing banks. Interchange ranges from approximately
1% to 2% of the transaction amount. Citibank (South Dakota) is required to
transfer to the master trust interchange attributed to cardholder charges for
merchandise and services in the accounts. Interchange is allocated to the
master trust on the basis of the ratio that the amount of cardholder charges
for merchandise and services in the accounts bears to the total amount of
cardholder charges for merchandise and services in the portfolio of credit card
accounts owned by Citibank (South Dakota). MasterCard International and VISA
may change the amount of interchange reimbursed to banks issuing their credit
cards.

The Credit Card Receivables

    The receivables in the credit card accounts as of June 24, 2000 included
$629,672,889 of finance charge receivables and $49,303,959,429 of principal
receivables--which amounts include overdue finance charge receivables and
overdue principal receivables. As of June 24, 2000, there were 39,009,042
accounts. Included within the accounts are inactive accounts that have no
balance. The accounts had an average principal receivable balance of $1,264 and
an average credit limit of $5,875. The average total receivable balance in the
accounts as a percentage of the average credit limit with respect to the
accounts was 22%. Approximately 81% of the accounts were opened before June
1998. Of the accounts, approximately 13.56% related to cardholders with billing
addresses in California, 10.47% in New York, 6.66% in Texas and 5.75% in
Florida. Not more than 5% of the accounts related to cardholders having billing
addresses in any other single state.

    The credit card accounts include receivables which, in accordance with the
servicer's normal servicing policies, were charged-off as uncollectible before
they were added to the master trust. However, for purposes of calculation of
the amount of principal receivables and finance charge receivables in the
master trust for any date, the balance of the charged-off receivables is zero
and the master trust owns only the right to receive recoveries on these
receivables.

    The following tables summarize the credit card accounts by various criteria
as of June 24, 2000. References to "Receivables Outstanding" in these tables
include both finance charge receivables and principal receivables. Because the
composition of the accounts will change in the future, these tables are not
necessarily indicative of the future composition of the accounts.

    Credit balances presented in the following table are a result of cardholder
payments and credit adjustments applied in excess of a credit card account's
unpaid balance. Accounts which have a credit balance are included because
receivables may be generated in these accounts in the future. Credit card
accounts which have no balance are included because receivables may be
generated in these accounts in the future.

Billing and Payments

    The credit card accounts have different billing and payment structures,
including different periodic finance charges and fees. The following
information reflects the current billing and payment characteristics of the
accounts.

                                      I-5
<PAGE>

    Citibank (South Dakota) sends monthly billing statements to cardholders
with balances at the end of each billing period. Each month a MasterCard or
VISA cardholder must make a minimum payment equal to the sum of

      (1) the greater of $20--or, if the then current balance is less than
  $20, that balance--and 1/48 of the then current balance,

      (2) any amount which is past due and

      (3) any amount which is in excess of the credit limit.

    The required minimum payment, however, cannot be less than the finance
charges billed.

    A periodic finance charge is assessed on the credit card accounts. The
periodic finance charge assessed on balances for purchases and cash advances
for a majority of the accounts is calculated by multiplying (1) the daily
balances for each day during the billing cycle by (2) the applicable daily
periodic finance charge rate, and summing the results for each day in the
billing period. The daily balance is calculated by taking the previous day's
balance, adding any new purchases or cash advances and fees, adding the daily
finance charge on the previous day's balance, and subtracting any payments or
credits. Cash advances are included in the daily balance from the date the
advances are made. Purchases are included in the daily balance generally from
the date of purchase. Periodic finance charges are not assessed in most
circumstances on purchase amounts if all balances shown in the previous billing
statement are paid in full by the due date indicated on the statement.

    The periodic finance charge assessed on balances in most credit card
accounts for purchases is currently the Prime Rate, as published in The Wall
Street Journal, plus a percentage ranging from 5.40% to 14.99%. As of the most
recent monthly reset date, the periodic finance charge on balances in most
accounts for purchases ranged from 14.90% to 24.49%. The periodic finance
charge assessed on balances in most credit card accounts for cash advances is
currently 19.99%. Citibank (South Dakota) may change the periodic finance
charge on accounts at any time by written notice to cardholders.

    Any increase in the finance charge will become effective upon the earlier
of subsequent use of a card and the expiration of a 25-day period from the date
the change was made effective--assuming failure on the part of the cardholder
to object to the new rate. Citibank (South Dakota) also offers promotional
rates of limited duration to attract new cardholders and to promote balance
transfers from other credit card issuers and the periodic finance charge on a
limited number of accounts may be greater or less than those assessed by
Citibank (South Dakota) generally.

    Before December 1993, Citibank (South Dakota) generally assessed an annual
membership fee of between $20 and $100 per account. Effective December 1, 1993,
Citibank (South Dakota) eliminated the annual membership fee for some premium
and nonpremium cardholders who met specified non-delinquency criteria. This
change did not apply to affinity or co-branded card products. In addition,
effective January 1, 1995, Citibank (South Dakota) eliminated the annual fees
applicable to some other accounts, including some of its affinity and co-
branded card products.

                                      I-6
<PAGE>

    Some of the accounts may be subject to additional fees, including:

  .   a late fee of $29 if Citibank (South Dakota) does not receive a
      required minimum payment by the payment date shown on the monthly
      billing statement, which fee is assessed monthly until the account is
      less than 30 days past due;

  .   a cash advance fee which is generally equal to 3.0% of the amount of
      the cash advance, subject to a minimum fee of $5;

  .   a returned payment fee of $29;

  .   a returned check fee of $29;

  .   a stop payment fee of $29; and

  .   a fee of $29 for each billing period with respect to each account with
      an outstanding balance over the credit limit established for that
      account.

    Payments by cardholders on the accounts are processed and applied to all
minimum amounts due, from the oldest to the most current, with respect to the
following items in the following order:

      (1) periodic finance charges on cash advances,

      (2) periodic finance charges on purchases,

      (3) cash advance amounts and

      (4) purchase amounts.

    When all minimum amounts due are paid, payments are generally allocated
first to cash advance balances and then to purchase balances. We cannot provide
any assurance that periodic finance charges, fees and other charges will remain
at current levels in the future.

                            Class A, Class B and Class C, issued on or about a
                            single date. The expected principal payment dates
                            and legal maturity dates of the subordinated
                            classes of a single issuance series will either be
                            the same as or later than those of the senior
                            classes of that series. No new notes will be issued
                            as part of a single issuance series after the
                            initial issuance date.

                            The subordinated notes of a single issuance series
                            provide subordination only to the senior notes of
                            that series.

                            Multiple Issuance Series. A multiple issuance
                            series is a series of notes consisting of three
                            classes: Class A, Class B and Class C. Each class
                            may consist of multiple subclasses. Notes of any
                            subclass can be issued on any date so long as there
                            are enough outstanding subordinated notes to
                            provide the necessary subordination protection for
                            outstanding and newly issued senior notes. See "The
                            Notes--Issuances of New Series, Classes and
                            Subclasses of Notes." The expected principal
                            payment dates and legal maturity dates of the
                            senior and subordinated classes of a multiple
                            issuance series may be different, and subordinated
                            notes may have expected principal payment dates and
                            legal maturity dates earlier than some or all
                            senior notes of the same series. Subordinated notes
                            will not be paid before their legal maturity date,
                            unless, after payment, the remaining subordinated
                            notes provide the required amount of subordination
                            protection for the senior notes of that series.

                            All of the subordinated notes of a multiple
                            issuance series provide subordination protection to
                            all of the senior notes of that series, regardless
                            of whether the subordinated notes are issued
                            before, at the same time as, or after the senior
                            notes of that series.

Interest Payments.........  Each class of notes, other than zero-coupon
                            discount notes, will bear interest from the date
                            and at the rate set forth or as determined in a
                            supplement to this prospectus. Interest on the
                            notes will be paid on the interest payment dates
                            specified in a supplement to this prospectus.

Expected Principal
 Payment Date and Legal
 Maturity Date............
                            The issuer expects to pay the stated principal
                            amount of each note in one payment on that note's
                            expected principal payment date. The expected
                            principal payment date of a note is two years
                            before its legal maturity date. The legal maturity
                            date is the date on which a note is legally
                            required to be fully paid. The expected principal
                            payment date and legal maturity date for a note
                            will be specified in a supplement to this
                            prospectus.

                            The issuer is obligated to pay the stated principal
                            amount of a note on its expected principal payment
                            date, or upon the occurrence of an early redemption
                            event or event of default only to the extent that
                            funds are available for that purpose and, in the
                            case of subordinated notes, that payment is
                            permitted by the subordination provisions of the
                            senior notes of the same series. The remedies a
                            noteholder may exercise following an event of
                            default and acceleration or on the legal maturity
                            date are described in "Covenants, Events of Default
                            and Early Redemption Events--Events of Default" and
                            "Deposit and Application of Funds--Sale of Credit
                            Card Receivables."

Stated Principal Amount,
 Outstanding Dollar
 Principal Amount and
 Nominal Liquidation
 Amount of Notes..........
                            Each note has a stated principal amount, an
                            outstanding dollar principal amount and a nominal
                            liquidation amount.

                            .  Stated Principal Amount. The stated principal
                               amount of a note is the amount that is stated on
                               the face of the note to be payable to the
                               holder. It can be denominated in U.S. dollars or
                               a foreign currency.

                            .  Outstanding Dollar Principal Amount. For U.S.
                               dollar notes, the outstanding dollar principal
                               amount

<PAGE>

                               will be the same as the stated principal amount,
                               less principal payments to noteholders. For
                               foreign currency notes, the outstanding dollar
                               principal amount will be the U.S. dollar
                               equivalent of the stated principal amount of the
                               notes, less dollar payments to derivative
                               counterparties with respect to principal. For
                               discount notes, the outstanding dollar principal
                               amount will be an amount stated in, or
                               determined by a formula described in, the
                               applicable supplement to this prospectus.

                            .  Nominal Liquidation Amount. The nominal
                               liquidation amount of a note is a U.S. dollar
                               amount based on the outstanding dollar principal
                               amount of the note, but after deducting

                               -- all reallocations of principal of that note
                                  to pay interest on senior classes of notes
                                  of the same series;

                               -- allocations of that note's proportionate
                                  share of the charge-offs of principal
                                  receivables in the master trust;

                               -- amounts on deposit in the principal funding
                                  subaccount for that note after giving effect
                                  to all reallocations to or from that
                                  subaccount;

                            and adding back all reimbursements, from excess
                            finance charge collections allocated to that note,
                            of reallocations of principal collections to pay
                            interest on senior classes of notes or charge-offs
                            of principal receivables in the master trust.
                            Excess finance charge collections are the finance
                            charge collections that remain after the payment of
                            interest and other required payments under the
                            master trust and with respect to the notes. For
                            more information, see the definition of "Excess
                            Finance Charge Collections" in the glossary.

                            The nominal liquidation amount of a class of notes
                            corresponds to the portion of the invested amount
                            of the collateral certificate that is allocated to
                            support that class of notes.

                            The aggregate nominal liquidation amount of all of
                            the notes is equal to the invested amount of the
                            collateral

                            certificate. The invested amount of the collateral
                            certificate corresponds to the amount of principal
                            receivables in the master trust that is allocated
                            to support the collateral certificate. For a more
                            detailed discussion, see "Invested Amount" in the
                            glossary. Anything that increases or decreases the
                            invested amount of the collateral certificate will
                            also increase or decrease the aggregate nominal
                            liquidation amount of the notes.

                            Upon a sale of credit card receivables held by the
                            master trust directed by a class of notes following
                            an event of default and acceleration, or on that
                            class's legal maturity date, as described in
                            "Deposit and Application of Funds--Sale of Credit
                            Card Receivables," the nominal liquidation amount
                            of that class will be reduced to zero.

                            For a detailed discussion of nominal liquidation
                            amount, see "The Notes--Stated Principal Amount,

                            Liquidation Amount."

Subordination of            Principal payments on the Class B notes of a series
 Principal................  are subordinated to payments on the Class A notes
                            of that series. Principal payments on the Class C
                            notes of a series are subordinated to payments on
                            the Class A notes and Class B notes of that series.
                            See "The Notes--Subordination of Principal" and
                            "Deposit and Application of Funds" for a discussion
                            of the extent, manner and limitations of the
                            subordination of Class B and Class C notes.

Sources of Funds to Pay
 the Notes................
                            The issuer will have the following sources of funds
                            to pay principal and interest on the notes:

                            .  The collateral certificate issued by Citibank
                               Credit Card Master Trust I. The collateral
                               certificate is an investor certificate issued by
                               the master trust to the issuer. It represents an
                               undivided interest in the assets of the master
                               trust. The master trust owns primarily credit
                               card receivables arising in selected MasterCard
                               and VISA revolving credit card accounts.
                               Citibank (South Dakota) and Citibank (Nevada)
                               have transferred the credit card receivables to
                               the master

                               trust in accordance with the terms of a pooling
                               and servicing agreement among Citibank (South
                               Dakota), Citibank (Nevada) and Bankers Trust
                               Company, as trustee. Both principal collections
                               and finance charge collections on the
                               receivables will, in general, be allocated pro
                               rata among holders of interests in the master
                               trust--including the collateral certificate--
                               based on the investment in credit card
                               receivables of each interest in the master
                               trust. If collections of receivables allocable
                               to the collateral certificate are less than
                               expected, payments of principal of and interest
                               on the notes could be delayed or remain unpaid.

                               The collateral certificate has an investment
                               grade rating from at least one nationally
                               recognized rating agency.

                            .  Derivative Agreements. Some classes of notes may
                               have the benefit of one or more derivative
                               agreements, including interest rate or currency
                               swaps, caps, collars, guaranteed investment
                               contracts or other similar agreements with
                               various counterparties. Citibank (South Dakota),
                               Citibank (Nevada) or any of their affiliates may
                               be counterparties to a derivative agreement. A
                               description of the specific terms of each
                               derivative agreement and each derivative
                               counterparty will be included in the applicable
                               supplement to this prospectus.

                            .  The Trust Accounts. The issuer has established a
                               collection account for the purpose of receiving
                               payments of finance charge collections and
                               principal collections from the master trust
                               payable under the collateral certificate.

                               The issuer has also established a principal
                               funding account, an interest funding account
                               and a Class C reserve account. Each one of
                               those accounts will have subaccounts for a
                               class or subclass of notes of a series. Also,
                               if specified in a supplement to this

                               Each month, distributions on the collateral
                               certificate will be deposited into the
                               collection account. Those deposits will then be
                               reallocated to

                               -- the principal funding account;

                               -- the interest funding account;

                               -- the Class C reserve account;

                               -- any supplemental account;

                               -- payments under any applicable derivative
                                  agreements; and

                               -- the other purposes as specified in "Deposit
                                  and Application of Funds" or in a supplement
                                  to this prospectus.

                            Funds on deposit in the principal funding account
                            and the interest funding account will be used to
                            make payments of principal of and interest on the
                            notes.

                            The Class C reserve account will initially not be
                            funded. If the finance charge collections generated
                            by the master trust fall below a level specified in
                            the applicable supplement to this prospectus, the
                            Class C reserve account will be funded as described
                            under "Deposit and Application of Funds--Targeted
                            Deposits to the Class C Reserve Account."

                            Funds on deposit in the Class C reserve account
                            will be available to holders of Class C notes to
                            cover shortfalls of interest payable on interest
                            payment dates. Funds on deposit in the Class C
                            reserve account will also be available to holders
                            of Class C notes on any day when principal is
                            payable, but only to the extent that the nominal
                            liquidation amount of the Class C notes plus funds
                            on deposit in the Class C principal funding account
                            is less than the outstanding dollar principal
                            amount of the Class C notes.

                            Only the holders of Class C notes will have the
                            benefit of the Class C reserve account. See
                            "Deposit and Application of Funds--Withdrawals from
                            the Class C Reserve Account."

Limited Recourse to the
 Issuer...................
                            The sole source of payment for principal of or
                            interest on a class of notes is provided by:

                            .  the portion of the principal collections and
                               finance charge collections received by the
                               issuer under the collateral certificate and
                               available to that class of notes after giving
                               effect to all allocations and reallocations;

                            .  funds in the applicable trust accounts for that
                               class of notes; and

                            .  payments received under any applicable
                               derivative agreement for that class of notes.

                            Noteholders will have no recourse to any other
                            assets of the issuer or any other person or entity
                            for the payment of principal of or interest on the
                            notes.

                            A further restriction applies if a class of notes
                            directs the master trust to sell credit card
                            receivables following an event of default and
                            acceleration, or on the applicable legal maturity
                            date, as described in "Deposit and Application of
                            Funds--Sale of Credit Card Receivables." In that
                            case, that class of notes has recourse only to the
                            proceeds of that sale and investment earnings on
                            those proceeds.

Security for the Notes....  The notes of all series are secured by a shared
                            security interest in the collateral certificate and
                            the collection account, but each class of notes is
                            entitled to the benefits of only that portion of
                            those assets allocated to it under the indenture.

                            Each class of notes is also secured by

                            .  a security interest in the applicable principal
                               funding subaccount;

                            .  the applicable interest funding subaccount;

                            .  in the case of a class of Class C notes, the
                               applicable Class C reserve subaccount;

                            .  any applicable supplemental account; and

                            .  by a security interest in any derivative
                               agreement for that class.

Redemption and Early
 Redemption of Notes......
                            If we specify in a supplement to this prospectus,
                            the issuer or a noteholder may, at its option,
                            redeem the notes of any series or class before its
                            expected principal payment date. The supplement
                            will indicate who will have that right of
                            redemption as well as the terms of that redemption.

                            In addition, the issuer is required to redeem any
                            note upon the occurrence of an early redemption
                            event with respect to that note, but only to the
                            extent of available funds. Available funds are
                            funds that are available to that note after giving
                            effect to all allocations and reallocations.

                            In addition, payment of subordinated notes that
                            provide subordination protection to senior notes is
                            limited as described under the heading "Limit on
                            Repayment of all Notes" below in this summary. It
                            is not an event of default if the issuer fails to
                            redeem a note because it does not have sufficient
                            funds available or because payment of the note is
                            delayed to provide required subordination
                            protection to a senior class of notes.

                            Early redemption events include the following:

                            .  for any note, the occurrence of the expected
                               principal payment date of that note;

                            .  each of the early amortization events applicable
                               to the collateral certificate, as described
                               under "The Master Trust--Early Amortization
                               Events";

                            .  mandatory prepayment of the entire collateral
                               certificate resulting from a breach of a
                               representation or warranty by Citibank (South
                               Dakota) or Citibank (Nevada) under the pooling
                               and servicing agreement;

                            .  some events relating to the performance of the
                               credit card receivables owned by the master
                               trust as described under "Covenants, Events of
                               Default and Early Redemption Events--Early
                               Redemption Events"; and

                            .  any additional early redemption events specified
                               in a supplement to this prospectus.

                            This list summarizes only some of the early
                            redemption events. See "Covenants, Events of
                            Default and Early Redemption Events--Early
                            Redemption Events" for a description of the early
                            redemption events and their consequences to holders
                            of notes.

Events of Default.........  The documents that govern the terms and conditions
                            of the notes include a list of adverse events known
                            as "events of default." Some events of default
                            result in an automatic acceleration of those notes,
                            and others result in the right of the holders of
                            the affected class of notes to demand acceleration
                            after an affirmative vote by holders of more than
                            50% of the affected class of notes.

                            Events of default for any class of notes include
                            the following:

                            .  the issuer fails to pay interest on any note of
                               that class within five business days of its due
                               date;

                            .  the issuer fails to pay in full principal of any
                               note of that class on its legal maturity date;

                            .  the issuer defaults on any covenant or breaches
                               any agreement under the indenture after
                               applicable notice and cure periods, and the
                               default or breach is materially adverse to
                               noteholders;

                            .  the occurrence of some events of bankruptcy,
                               insolvency or reorganization of the issuer; or

                            .  any additional events of default specified in a
                               supplement to this prospectus.

                            This list summarizes only some of the events of
                            default. See "Covenants, Events of Default and
                            Early Redemption Events--Events of Default" for a
                            description of the events of default and their
                            consequences to holders of notes.

                            It is not an event of default if the stated
                            principal amount of a note is not paid on its
                            expected principal payment date.

Event of Default            After an event of default and acceleration of a
 Remedies.................  class of notes, funds on deposit in the principal
                            funding subaccount and the interest funding
                            subaccount for that class of notes will be applied
                            to pay principal of and interest on those notes.
                            Then, in each following month, principal
                            collections and finance charge collections
                            allocated to those notes will be applied to make
                            monthly principal and interest payments on those
                            notes until the earlier of the date those notes are
                            paid in full or the legal maturity date of those
                            notes. However, if your notes are subordinated
                            notes, you will receive full payment of principal
                            of those notes only if and to the extent that,
                            after giving effect to that payment, the required
                            subordinated amount will be maintained for senior
                            notes in that series. See "Deposit and Application
                            of Funds--Limit on Repayments of Subordinated
                            Classes of Single Issuance Series" and "--Limit on
                            Repayments of Subordinated Classes of Multiple
                            Issuance Series."

                            If an event of default of a class of notes occurs
                            and that class is accelerated, the indenture
                            trustee may, and at the direction of the majority
                            of the noteholders of that class will, direct the
                            master trust to sell credit card receivables.
                            However, this sale of receivables may occur only if
                            the conditions specified in "Covenants, Events of
                            Default and Early Redemption Events--Events of
                            Default" are satisfied or on the legal maturity
                            date of that class of notes. The proceeds of a sale
                            of credit card receivables will be deposited
                            directly to the principal funding subaccount for
                            the accelerated notes. Upon the sale of the
                            receivables of the accelerated notes, the nominal
                            liquidation amount of those notes will be reduced
                            to zero. See "Deposit and Application of Funds--
                            Sale of Credit Card Receivables."

Limit on Repayment of All
 Notes....................
                            You may not receive full repayment of your notes if

                            .  the nominal liquidation amount of your notes has
                               been reduced by charge-offs of principal
                               receivables in the master trust or as the result
                               of reallocations of principal collections to pay
                               interest on senior classes of notes, and those
                               amounts have not been reimbursed from excess
                               finance charge collections; or

                               are insufficient.

                            Subordinated notes that reach their expected
                            principal payment date, or that have an early
                            redemption event, event of default or other
                            optional or mandatory redemption, will not be paid
                            to the extent that those notes are necessary to
                            provide the required subordinated amount to senior
                            classes of notes of the same series. If a class of
                            subordinated notes cannot be paid because of the
                            subordination provisions of the indenture,
                            prefunding of the principal funding subaccounts for
                            the senior notes of the same series will begin, as
                            described in "Deposit and Application of Funds--
                            Targeted Deposits of Principal Collections to the
                            Principal Funding Account." After that time, the
                            remaining amount of those subordinated notes will
                            be paid only to the extent that:

                            .  enough notes of senior classes of that series
                               are repaid so that the subordinated notes that
                               are paid are no longer necessary to provide the
                               required subordinated amount; or

                            .  in the case of multiple issuance series, new
                               classes of subordinated notes of that series are
                               issued so that the subordinated notes that are
                               paid are no longer necessary to provide the
                               required subordinated amount; or

                            .  the principal funding subaccounts for the senior
                               classes of notes of that series are fully
                               prefunded so that none of the subordinated notes
                               that are paid are necessary to provide the
                               required subordinated amount; or

                            .  the subordinated notes reach their legal
                               maturity date.

                            On the legal maturity date of a class of notes, all
                            amounts on deposit in the principal funding
                            subaccount for that class, after giving effect to
                            all allocations, reallocations and sales of
                            receivables, will be paid to the noteholders of
                            that class, even if payment would reduce the amount
                            of subordination protection below the required
                            subordinated amount of the senior classes of that
                            series.

                            be an association or a publicly traded partnership
                            taxable as a corporation. In addition, noteholders
                            will agree, by acquiring notes, to treat the notes
                            as debt of Citibank (South Dakota) and Citibank
                            (Nevada) for federal, state and local income and

Ratings...................  It is a condition to the issuance of the notes
                            offered by this prospectus that they are rated no
                            lower than the following rating categories by at
                            least one nationally recognized rating agency:

                            If a class of notes has subclasses, each subclass
                            offered by this prospectus will have the same
                            rating requirement as the class of notes of which
                            it is a part.

                            The issuer may also issue notes not offered by this
                            prospectus that do not meet these rating
                            requirements so long as the issuer obtains (i)
                            confirmation from each rating agency that has rated
                            any outstanding notes that the new series, class or
                            subclass of notes to be issued will not cause a
                            reduction or withdrawal of the ratings of any
                            outstanding notes rated by that rating agency and

                                 RISK FACTORS

    The following is a summary of the material risks that apply to an
investment in the notes. The remainder of this prospectus and the attached
supplement provide much more detailed information about these risks. You
should consider the following risk factors in deciding whether to purchase the
notes.

    There is a glossary beginning on page 111 where you will find the
definitions of some terms used in this prospectus.

Only some of the assets of the issuer are available for payments on any class
of notes

    The sole source of payment of principal of or interest on a class of notes
is provided by:

  .   the portion of the principal collections and finance charge
      collections received by the issuer under the collateral certificate
      and available to that class of notes after giving effect to all
      allocations and reallocations;

  .   the applicable trust accounts for that class of notes; and

  .   payments received under any applicable derivative agreement for that
      class of notes.

As a result, you must rely only on the particular allocated assets as security
for your class of notes for repayment of the principal of and interest on your
notes. You will not have recourse to any other assets of the issuer or any
other person for payment of your notes. See "Sources of Funds to Pay the
Notes."

    A further restriction applies if a class of notes directs the master trust
to sell credit card receivables following an event of default and
acceleration, or on the applicable legal maturity date, as described in
"Deposit and Application of Funds--Sale of Credit Card Receivables." In that
case, that class of notes has recourse only to the proceeds of that sale and
investment earnings on those proceeds.

Cardholder payment patterns and credit card usage may affect the timing and
amount of payments to you

    The amount of principal collections available to pay your notes on any
principal payment date or to make deposits into the principal funding account
will depend on many factors, including:

  .the rate of repayment of credit card balances by cardholders, which may be
      earlier or later than expected;

  .the extent of credit card usage by cardholders, and the creation of
      additional receivables in the accounts designated to the master trust;
      and

  .the rate of default by cardholders, which means that receivables may not
      be paid at all.

                                      15
<PAGE>

    Changes in payment patterns and credit card usage result from a variety of
economic, social and legal factors. Economic factors include the rate of
inflation, unemployment levels and relative interest rates. Social factors
include consumer confidence levels and the public's attitude about incurring
debt and the stigma of personal bankruptcy. For some of the legal factors, see
"--Legal aspects could affect the timing and amount of payments to you" below.
The availability of incentive or other award programs may also affect
cardholders' actions. We cannot predict how these or other factors will affect
repayment patterns or card use and, consequently, the timing and amount of
payments on your notes.

Class A and Class B notes of a multiple issuance series can lose their
subordination protection under some circumstances

    Class B notes and Class C notes of a multiple issuance series may have
expected principal payment dates and legal maturity dates earlier than some or
all of the notes of the senior classes of that series.

    If notes of a subordinated class reach their expected principal payment
date at a time when they are needed to provide subordination protection to the
senior classes of the same series, and the issuer is unable to issue additional
notes of that subordinated class, prefunding of the senior classes of that
series will begin. The principal funding subaccounts for the senior classes
will be prefunded with monthly collections of principal receivables in the
master trust allocable to that series in an amount necessary to maintain the
required subordination protection for the senior classes, if available. See
"Deposit and Application of Funds--Targeted Deposits of Principal Collections
to the Principal Funding Account."

    There will be a two-year period between the expected principal payment date
and the legal maturity date of the subordinated notes to prefund the principal
funding subaccounts for the senior classes of that series. The subordinated
notes will be paid on their legal maturity date, to the extent that funds are
available from the applicable Class C reserve subaccount or from proceeds of
the sale of receivables or otherwise, whether or not the senior classes of
notes of that series have been fully prefunded.

    If the rate of repayment of principal receivables in the master trust were
to decline to less than an average of 4 1/2% per month during this two-year
prefunding period, then the principal funding subaccounts for the senior
classes of notes may not be fully prefunded before the legal maturity date of
the subordinated notes. In that event and only to the extent not fully
prefunded, the senior classes of that series would lose their subordination
protection on the legal maturity date of those subordinated notes, unless
additional subordinated notes of that class were issued or a sufficient amount
of senior notes of that series have matured so that the remaining outstanding
subordinated notes provide the necessary subordination protection.

    Since January 1995 the monthly rate of repayment of principal receivables
in the master trust has ranged from a low of 16.59% to a high of more than 21%.
Principal payment rates may change due to a variety of factors including
economic, social and legal factors, changes in the terms of credit card
accounts by Citibank (South Dakota) or the addition of credit card

                                       16
<PAGE>

accounts with different characteristics to the master trust. There can be no
assurance that the rate of principal repayment will remain in this range in the
future.

    Monthly reports concerning the performance of the credit card receivables
in the master trust will be filed with the SEC on Form 8-K. The monthly rate of
repayment of principal receivables will be included in these publicly-available
reports.

You may receive principal payments earlier or later than the expected principal
payment date

    There is no assurance that the stated principal amount of your notes will
be paid on its expected principal payment date.

    The effective yield on the credit card receivables owned by the master
trust could decrease due to, among other things, a change in periodic finance
charges on the accounts, an increase in the level of delinquencies or increased
convenience use of the card whereby cardholders pay their credit card balance
in full each month and incur no finance charges. A significant decrease in the
amount of credit card receivables in the master trust for any reason could
result in an early redemption event and in early payment of your notes, as well
as decreased protection to you against defaults on the accounts. If surplus
finance charge collections calculated using a three-month moving average
decreases below the required surplus finance charge amount, an early redemption
event will occur and could result in an early payment of your notes. See
"Covenants, Events of Default and Early Redemption Events--Early Redemption
Events." For a discussion of surplus finance charge collections and required
surplus finance charge amount, see "Surplus Finance Charge Collections" and
"Required Surplus Finance Charge Amount" in the glossary.

    If, for any reason, cardholders make payments on their credit card accounts
later than expected or default on the payments on their credit card accounts
the allocations of principal collections to the collateral certificate and to
the notes may be reduced, and the principal of the notes may be paid later than
expected or not paid at all.

Reductions in the nominal liquidation amount could reduce payment of principal
to you

    You may not receive full repayment of your notes if the nominal liquidation
amount of your notes has been reduced by charge-offs of principal receivables
in the master trust or as the result of reallocations of principal collections
to pay interest on senior classes of notes, and those amounts have not been
reimbursed from excess finance charge collections. See "Deposit and Application
of Funds--Final Payment of the Notes." For a discussion of nominal liquidation
amount, see "The Notes--Stated Principal Amount, Outstanding Dollar Principal
Amount and Nominal Liquidation Amount of Notes."

Allocations of charged-off receivables in the master trust could reduce
payments to you

    Citibank (South Dakota), as servicer of the master trust, will charge off
the receivables arising in the accounts in the master trust portfolio if the
receivables become uncollectible or

                                       17
<PAGE>

are otherwise more than 184 days delinquent. The collateral certificate will be
allocated a portion of these charged-off receivables. If the amount of charged-
off receivables allocated to the collateral certificate exceeds the amount of
funds available for reimbursement of those charge-offs, the issuer, as the
holder of the collateral certificate, may not receive a sufficient amount under
the collateral certificate to pay the full stated principal amount of your
notes. See "The Master Trust Receivables and Accounts--Loss and Delinquency
Experience" in Annex I to the supplement to this prospectus, "Sources of Funds
to Pay the Notes--The Collateral Certificate," "Deposit and Application of
Funds--Allocation of Principal Collections to Accounts," "--Targeted Deposits
of Principal Collections to the Principal Funding Account," "--Allocation to
Principal Funding Subaccounts" and "--Final payment of the Notes."

Reset of interest rate on credit card receivables in the master trust may
reduce the amount of finance charge collections available for interest payments
on the notes

    A majority of the credit card receivables in the master trust bear interest
at the prime rate plus a margin. The notes generally bear interest at a fixed
or floating rate. If the prime rate declines, the amount of collections of
finance charge receivables on the accounts in the master trust may be reduced
while the interest payments on fixed rate notes required to be funded out of
those collections will remain constant.

    Changes in the interest rate indices applicable to floating rate notes
might not be reflected in the prime rate, resulting in an increase or decrease
in the difference between the amount of collections of finance charge
receivables on the accounts in the master trust and the amount of interest
payable on the floating rate notes.

    In addition, a decrease in the difference between collections of finance
charge receivables and those collections allocated to make interest payments on
the notes could cause an early redemption event which could result in early
payment of your notes. See "Covenants, Events of Default and Early Redemption
Events--Early Redemption Events."

Citibank (South Dakota)'s ability to change terms of the credit card accounts
could alter payment patterns

    The master trust owns the credit card receivables generated in designated
credit card accounts, but Citibank (South Dakota) continues to own the accounts
themselves. Citibank (South Dakota) thus has the right to determine the fees,
periodic finance charges including the interest rate index used to compute
periodic finance charges, and other charges that will apply to the credit card
accounts. Citibank (South Dakota) may also change the minimum monthly payment
or other terms of the accounts. A decrease in the effective yield on the credit
card receivables could cause an early redemption event, resulting in an early
payment of the notes. See "Covenants, Events of Default and Early Redemption
Events--Early Redemption Events." Also, changes in account terms could affect
payment patterns on the credit card receivables, which could cause principal of
the notes to be paid earlier or later than anticipated.


                                       18
<PAGE>

    Citibank (South Dakota) has agreed generally to avoid taking actions that
would

  .   reduce the portfolio yield of the receivables in the master trust
      below specified levels;

  .   change the terms of the credit card accounts designated to the master
      trust, unless it is changing the terms of all similar accounts in its
      portfolio; or

  .   decrease the finance charges on the credit card accounts designated to
      the master trust below a specified level after the occurrence of an
      early redemption event resulting from surplus finance charge
      collections being less than the required surplus finance charge
      amount.

For a discussion of portfolio yield, surplus finance charge collections and
required surplus finance charge amount, see "Portfolio Yield," "Surplus Finance
Charge Collections" and "Required Surplus Finance Charge Amount" in the
glossary.

    There are no other restrictions on Citibank (South Dakota)'s ability to
change the terms of the credit card accounts designated to the master trust,
and we can provide no assurance that finance charges or other fees will not be
reduced.

Addition of accounts to the master trust may affect credit quality and lessen
the issuer's ability to make payments to you

    The assets of the master trust, and therefore the assets allocable to the
collateral certificate held by the issuer, change every day. Citibank (South
Dakota) and Citibank (Nevada) may choose, or may be required, to add credit
card receivables to the master trust. The credit card accounts from which these
receivables arise may have different terms and conditions from the credit card
accounts already designated for the master trust. For example, the new credit
card accounts may have higher or lower fees or interest rates, or different
payment terms. We cannot guarantee that new credit card accounts will have the
same credit quality as the credit card accounts currently designated for the
master trust. If the credit quality of the assets in the master trust were to
deteriorate, the issuer's ability to make payments on the notes could be
adversely affected. See "The Master Trust--Master Trust Assets."

    The issuer's ability to make payments on the notes will be impaired if
sufficient new credit card receivables are not generated by Citibank (South
Dakota) and Citibank (Nevada). We do not guarantee that new credit card
receivables will be created, that any credit card receivables will be added to
the master trust or that credit card receivables will be repaid at a particular
time or with a particular pattern.

Citibank (South Dakota) and Citibank (Nevada) may not be able to designate new
accounts to the master trust when required by the pooling and servicing
agreement

    The pooling and servicing agreement provides that Citibank (South Dakota)
and Citibank (Nevada) must add additional credit card receivables to the master
trust if the total amount of principal receivables in the master trust falls
below specified percentages of the

                                       19
<PAGE>

total invested amounts of investor certificates in the master trust. There is
no guarantee that Citibank (South Dakota) and Citibank (Nevada) will have
enough receivables to add to the master trust. If Citibank (South Dakota) and
Citibank (Nevada) do not make an addition of receivables within five business
days after the date they are required to do so, an early amortization event
will occur with respect to the collateral certificate. This would constitute an
early redemption event and could result in an early payment of your notes. See
"The Master Trust--Master Trust Assets" and "--Early Amortization Events" and
"Covenants, Events of Default and Early Redemption Events--Early Redemption
Events."

Class B notes and Class C notes bear losses before Class A notes

    Class B notes of a series are subordinated in right of payment of principal
to Class A notes of that series, and Class C notes of a series are subordinated
in right of payment of principal to Class A notes and Class B notes of that
series. In general, interest payments on a class of notes are not subordinated
in right of payment to interest payments on any other class of notes.

    In all series, principal collections that are allocable to subordinated
classes of notes may be reallocated to pay interest on senior classes of notes
of that series. In addition, losses on charged-off receivables in the master
trust are allocated first to the subordinated classes of a series. See "The
Notes--Stated Principal Amount, Outstanding Dollar Principal Amount and Nominal
Liquidation Amount--Nominal Liquidation Amount" and "Deposit and Application of
Funds--Allocation of Principal Collections to Accounts." If these reallocations
and losses are not reimbursed from excess finance charge collections, the full
stated principal amount of the subordinated classes of notes may not be repaid.

    If there is a sale of the credit card receivables owned by the master trust
due to a sale or repurchase of the interest represented by the collateral
certificate after a default by the servicer of the master trust, the net
proceeds of the sale allocable to principal payments with respect to the
collateral certificate will generally be used first to pay amounts due to Class
A noteholders, next to pay amounts due to Class B noteholders of that series,
and lastly, for amounts due to Class C noteholders. This could cause a loss to
Class C noteholders, if the amount available to them plus the amount, if any,
available under their credit enhancement--the applicable Class C reserve
account--is not enough to pay the Class C notes in full. It could also cause a
loss to Class B noteholders if the amount available to them plus the amount, if
any, available under their credit enhancement--the applicable Class C notes--is
not enough to pay the Class B notes in full.

Payment of Class B notes and Class C notes may be delayed due to the
subordination provisions

    For a single issuance series, in general no payment of principal of Class B
notes of that series will be made until all principal of Class A notes of that
series has been paid in full, and no payment of principal of Class C notes of
that series will be made until all principal of Class A notes and Class B notes
of that series has been paid in full, even if the subordinated notes have
reached their expected principal payment date, or have had an early redemption

                                       20
<PAGE>

event, event of default or other optional or mandatory redemption. See "The
Notes--Subordination of Principal" and "Deposit and Application of Funds--Limit
on Repayments of Subordinated Classes of Single Issuance Series."

    For a multiple issuance series, subordinated notes generally, except as
noted in the following paragraph, will be paid only to the extent that they are
not necessary to provide the required subordinated amount to senior classes of
notes of the same series. In addition, if a senior class of notes has reached
its expected principal payment date, or has had an early redemption event,
event of default or other optional or mandatory redemption, any principal
collections allocable to a subordinated class of notes or funds on deposit in
the principal funding account for a subordinated class of notes of the same
series--other than proceeds of sales of credit card receivables or funds from
the Class C reserve account--will be reallocated to the senior class.

    If you have subordinated notes of a single issuance series or multiple
issuance series that reach their expected principal payment date, or that have
an early redemption event, event of default or other optional or mandatory
redemption, and your notes cannot be paid because of the subordination
provisions of the indenture, prefunding of the principal funding subaccounts
for the senior notes of your series will begin, as described in "Deposit and
Application of Funds--Targeted Deposits of Principal Collections to the
Principal Funding Account." After that time, your notes will be paid only if,
and to the extent that:

  .   enough notes of senior classes of that series are repaid so that your
      notes are no longer necessary to provide the required subordinated
      amount, or

  .   in the case of multiple issuance series, new classes of subordinated
      notes of the same series are issued so that your notes are no longer
      necessary to provide the required subordinated amount, or

  .   the principal funding subaccounts for the senior classes of notes of
      that series are fully prefunded so that your notes are no longer
      necessary to provide the required subordinated amount; or

  .   your notes reach their legal maturity date.

This may result in a delay or loss of principal payments to holders of
subordinated notes. See "Deposit and Application of Funds--Limit on Repayment
of Subordinated Classes of Single Issuance Series," "--Limit on Repayment of
Subordinated Classes of Multiple Issuance Series" and "--Targeted Deposits of
Principal Collections to the Principal Funding Account--Prefunding of the
Principal Funding Account for Senior Classes."

You may not be able to reinvest any early redemption proceeds in a comparable
security

    If your notes are redeemed at a time when prevailing interest rates are
relatively low, you may not be able to reinvest the redemption proceeds in a
comparable security with an effective interest rate as high as that of your
notes.


                                       21
<PAGE>

Your ability to resell notes may be limited

    It may be difficult for you to resell your notes at the time and at the
price you desire. We expect that the underwriters of and agents for the notes
will make a market in the notes, but no underwriter or agent will be required
to do so. Even if a secondary market does develop, it may not provide you with
liquidity for the notes, and it may not continue until the maturity of the
notes.

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

If the ratings of the notes are lowered or withdrawn, their market value could
decrease

    The initial rating of a note addresses the likelihood of the payment of
interest on that note when due and the ultimate payment of principal of that
note by its legal maturity date. The ratings do not address the possibility of
an early payment or acceleration of a note, which could be caused by an early
redemption event or an event of default. See "Covenants, Events of Default and
Early Redemption Events--Early Redemption Events" and "--Events of Default."

    The ratings of the notes are not a recommendation to buy, hold or sell the
notes. The ratings of the notes may be lowered or withdrawn entirely at any
time by the applicable rating agency. The market value of the notes could
decrease if the ratings are lowered or withdrawn. See "Prospectus Summary--
Ratings."

Issuance of additional notes or master trust investor certificates may affect
the timing and amount of payments to you

    The issuer expects to issue notes from time to time, and the master trust
may issue new investor certificates from time to time. New notes and master
trust investor certificates may be issued without notice to existing
noteholders, and without their consent, and may have different terms from
outstanding notes and investor certificates. For a description of the
conditions that must be met before the master trust can issue new investor
certificates or the issuer can issue new notes, see "The Master Trust--Master
Trust Issuances; Sellers' Interest" and "The Notes--Issuances of New Series,
Classes and Subclasses of Notes."

    The issuance of new notes or master trust investor certificates could
adversely affect the timing and amount of payments on outstanding notes. For
example, if notes issued after your notes have a higher interest rate than your
notes, the result could be that there is a smaller amount of finance charge
collections available to pay interest on your notes. Also, when new notes or
investor certificates are issued, the voting rights of your notes may be
diluted. See "Risk Factors--You may have limited control of actions under the
indenture and the pooling and servicing agreement."

Legal aspects could affect the timing and amount of payments to you

  Transfer of credit card receivables could be a security interest

    Although Citibank (South Dakota) and Citibank (Nevada) sell credit card
receivables to the master trust, it is possible that a court could treat those
sales as an assignment of collateral for the benefit of the holders of the
master trust investor certificates in the master trust, including the
collateral certificate, instead of as a sale. If the transfer of credit card
receivables to the master trust were deemed to create a security interest under
the South Dakota or Nevada Uniform Commercial Code:

  .   A tax or government lien on property of Citibank (South Dakota) or
      Citibank (Nevada) arising before the credit card receivables came into
      existence may have priority over the master trust's interest, and
      therefore over the issuer's interest, in the receivables.

  .   If the FDIC were appointed receiver of Citibank (South Dakota) or
      Citibank (Nevada), its administrative expenses may also have priority
      over the master trust's interest, and therefore the issuer's interest,
      in the receivables.

  Insolvency or bankruptcy of Citibank (South Dakota) or Citibank (Nevada)
  could adversely affect you

    If the FDIC were appointed a conservator or receiver for either Citibank
(South Dakota) or Citibank (Nevada), then an early amortization event would
occur under the pooling and servicing agreement, thus causing an early
redemption event for the notes. Under the terms of the pooling and servicing
agreement, no new principal receivables would be transferred to the master
trust and the master trust trustee would sell the credit card receivables
unless holders of more than 50% of the unpaid principal amount of master trust
investor certificates of each class of each series, including the collateral
certificate, Citibank (South Dakota), unless it is insolvent, Citibank
(Nevada), unless it is insolvent, and each other holder, if any, of an interest
in the master trust, give the master trust trustee other instructions. In that
event

  .   the master trust would terminate;

  .   an early amortization event would occur with respect to the collateral
      certificate, thus causing an early payment of the notes; and

  .   you would have a loss if proceeds from the sale of the credit card
      receivables allocable to the collateral certificate were insufficient
      to pay your notes in full.

However, the Federal Deposit Insurance Act, as amended by the Financial
Institutions Reform, Recovery and Enforcement Act of 1989, gives the FDIC
powers when it is acting as receiver or conservator for a bank, including the
power:

  .   to prevent the start of an early amortization period under the pooling
      and servicing agreement, thereby preventing the termination of the
      master trust and a possible early payment of the notes;

  .   to continue to require Citibank (South Dakota) and Citibank (Nevada)
      to transfer new principal receivables to the master trust; and

                                       23
<PAGE>

  .   to prevent the early sale, liquidation or disposition of the credit
      card receivables in the master trust.

In addition, if Citibank (South Dakota) defaults on its obligations as servicer
under the pooling and servicing agreement solely because a conservator or
receiver is appointed for it, the conservator or receiver might have the power
to prevent either the master trust trustee or the master trust
certificateholders from appointing a new servicer under the pooling and
servicing agreement.

    We believe that the FDIC, acting as a receiver or conservator of Citibank
(South Dakota) or Citibank (Nevada), would not interfere with the continued
transfer and liquidation of credit card receivables between that bank and the
master trust. The transfer of the receivables by the banks to the master trust
has been documented as a sale. If the transfer constitutes a sale under general
applicable law, and if no fraud or other misconduct has occurred and the
pooling and servicing agreement satisfies the regulatory requirements of the
Federal Deposit Insurance Act, as amended by the Financial Institutions Reform,
Recovery and Enforcement Act of 1989, the FDIC as conservator or receiver for
one of the banks could not reclaim the receivables or limit that bank's
subsequent transfer or exercise of rights with respect to the receivables.

    The transfer of the receivables by the banks to the master trust, however,
may constitute the grant of a security interest under general applicable law
rather than a sale. Nevertheless, the FDIC has issued regulations surrendering
certain rights under the FDIA to reclaim, recover, or recharacterize a
financial institution's transfer of financial assets such as the receivables
if:

  .   the transfer involved a securitization of the financial assets and
      meets specified conditions for treatment as a sale under relevant
      accounting principles;

  .   the financial institution received adequate consideration for the
      transfer;

  .   the parties intended that the transfer constitute a sale for accounting
      purposes; and

  .   the financial assets were not transferred fraudulently, in
      contemplation of the financial institution's insolvency, or with the
      intent to hinder, delay, or defraud the financial institution or its
      creditors.

The pooling and servicing agreement and the transfer of the receivables by the
banks to the master trust have been structured to satisfy all of these
conditions.

    If a condition required under the FDIC's regulations were found not to have
been met, however, the FDIC could seek to recover or reclaim the receivables.
We believe the FDIC would not seek to do so, so long as:

  .   the banks' transfer of the receivables to the master trust is the grant
      of a valid security interest in the receivables to the master trust;

  .   the security interest is validly perfected before the insolvency of the
      bank and was neither taken in contemplation of its insolvency nor with
      the intent to hinder, delay or defraud the bank or its creditors; and

                                       24
<PAGE>

  .   the pooling and servicing agreement is continuously an official record
      of the bank and represents a bona fide and arm's length transaction
      undertaken for adequate consideration in the ordinary course of
      business.

The FDIC could, however, assert a contrary position, and seek to:

  .   avoid the master trust's security interest in the credit card
      receivables;

  .   require the master trust trustee to go through an administrative claims
      procedure to establish its right to payments collected on the credit
      card receivables in the master trust;

  .   request a stay of proceedings with respect to Citibank (South Dakota)
      or Citibank (Nevada), as the case may be; or

  .   repudiate the pooling and servicing agreement and limit the master
      trust's resulting claim to "actual direct compensatory damages"
      measured as of the date of receivership.

If the FDIC were to take any of those actions, payments of outstanding
principal and interest on the notes could be delayed and possibly reduced.

  Changes in consumer protection laws may impede Citibank (South Dakota)'s
  collection efforts

    The credit card industry is extensively regulated by federal, state and
local consumer protection laws. The most significant federal laws are

  .   the Federal Truth-in-Lending Act;

  .   the Equal Credit Opportunity Act;

  .   the Fair Credit Reporting Act; and

  .   the Fair Debt Collection Practices Act.

These laws affect how loans are made, enforced and collected. The United States
Congress and the states may pass new laws, or may amend existing laws, to
regulate further the credit card industry or to reduce finance charges or other
fees applicable to credit card accounts. This could make collection of credit
card receivables more difficult for Citibank (South Dakota), as servicer, and
could decrease the amount of finance charge receivables received by the master
trust and thus available for interest payments on the notes.

    In recent years, interest rates charged by credit card issuers have come
under increased scrutiny by consumer groups and lawmakers. Changes in
applicable laws could add limitations on the finance charges and other fees
related to the credit card accounts. For example, if an interest rate cap were
imposed by law at a level substantially lower than the

                                       25
<PAGE>

annual percentage rates currently charged on the credit card accounts, the
decrease in finance charge collections could result in an early redemption
event and a possible early payment of the notes.

    Citibank (South Dakota) and Citibank (Nevada) make representations and
warranties about their compliance with applicable laws and regulations, and
about the validity and enforceability of the credit card receivables and the
accounts. These representations and warranties are made for the benefit of the
holders of investor certificates under the master trust, and are not made for
your benefit. If the credit card receivables do not comply with applicable law
in all material respects, the issuer's interest in the receivables will be
reassigned to Citibank (South Dakota) or Citibank (Nevada), and you will have
no other remedy.

    A breach of the representations and warranties by Citibank (South Dakota)
or Citibank (Nevada) relating to the credit card receivables and accounts
generally results in the sellers' interest being reduced by the amount of the
reassigned receivables. However, a breach of some representations and
warranties results in Citibank (South Dakota) and Citibank (Nevada) paying a
reassignment price for the receivables generally equal to the aggregate
invested amount of all series of investor certificates, including the
collateral certificate, issued by the master trust, plus accrued and unpaid
interest on those certificates. See "The Master Trust--Master Trust Assets." A
breach of these representations and warranties could result in a possible early
payment of the notes.

Competition in the credit card industry could affect the timing and amount of
payments to you

    The credit card industry is very competitive and operates in a legal and
regulatory environment increasingly focused on the cost of services charged to
consumers for credit cards. Through advertising, target marketing, pricing
competition and incentive programs, credit card issuers compete to attract and
retain customers. Citibank (South Dakota), Citibank (Nevada) and other credit
card issuers may offer cards with lower fees and/or finance charges than the
credit card accounts that have been designated as part of the master trust.
Also, Citibank (South Dakota) and Citibank (Nevada) may solicit existing
cardholders to open other accounts with benefits not available under the
designated accounts. If cardholders choose to use competing sources of credit,
the rate at which new credit card receivables are generated may be reduced and
the pattern of payments may be affected. If the credit card receivables decline
significantly, Citibank (South Dakota) and Citibank (Nevada) may be required to
designate additional accounts to the master trust, or an early amortization
event with respect to the collateral certificate could occur and the notes
could be paid early.

    In 1998, the U.S. Justice Department sued MasterCard International
Incorporated, VISA U.S.A., Inc. and VISA International, Inc. in the U.S.
District Court for the Southern District of New York. The suit asserts that
joint control of both the MasterCard and VISA associations by the same group of
banks lessens competition and therefore violates the antitrust laws. The
government contends that banks should not be permitted to participate in

                                       26
<PAGE>

the governance of both associations. The government is also challenging the
rules of the associations that restrict banks from issuing American Express or
Discover cards. MasterCard and VISA have both stated that they believe the suit
to be without merit, and have denied the allegations.

    In 1996, Walmart and several other retailers sued MasterCard International
Incorporated, VISA U.S.A. Inc., and Visa International in the U.S. District
Court for the Eastern District of New York. The suit asserts that the rules of
both associations regarding the uniform acceptance of all Visa and MasterCard
cards, including debit Visa and MasterCard cards, constitute an illegal tying
arrangement. Both MasterCard and VISA have stated that they believe the suit to
be without merit, and have denied the allegations.

    We cannot predict the outcome of the litigations described above or their
effect on the competitive environment in the credit card industry.

You may have limited control of actions under the indenture and the pooling and
servicing agreement

    Under the indenture, some actions require the vote of noteholders holding a
specified percentage of the aggregate outstanding dollar principal amount of
notes of a series, class or subclass or all the notes. These actions include
accelerating the payment of principal of the notes or consenting to amendments
relating to the collateral certificate. In the case of votes by series or votes
by holders of all of the notes, the Class A outstanding dollar principal amount
will generally be substantially greater than the Class B or Class C outstanding
dollar principal amounts. Consequently, the Class A noteholders will generally
have the ability to determine whether and what actions should be taken. The
Class B and Class C noteholders will generally need the concurrence of the
Class A noteholders to cause actions to be taken.

    The collateral certificate is an investor certificate under the pooling and
servicing agreement, and noteholders have indirect voting rights under the
pooling and servicing agreement. See "Meetings, Voting and Amendments." Under
the pooling and servicing agreement, some actions require the vote of a
specified percentage of the aggregate principal amount of all of the investor
certificates. These actions include causing the early amortization of the
investor certificates or consenting to amendments to the pooling and servicing
agreement. In the case of votes by holders of all of the investor certificates,
the outstanding principal amount of the collateral certificate is and may
continue to be substantially smaller than the outstanding principal amount of
the other series of investor certificates. Consequently, the holders of
investor certificates--other than the collateral certificate--will generally
have the ability to determine whether and what actions should be taken. The
noteholders, in exercising their voting powers under the collateral
certificate, will generally need the concurrence of the holders of the other
investor certificates to cause actions to be taken.

Your remedies upon default may be limited

    Your remedies may be limited if an event of default under your class of
notes occurs. After an event of default affecting your class of notes, any
funds in the principal funding

                                       27
<PAGE>

subaccount and the interest funding subaccount with respect to that class of
notes will be applied to pay principal of and interest on those notes or
reallocated or retained for the benefit of senior classes of notes. Then, in
each following month, principal collections and finance charge collections
allocated to those notes will either be deposited into the applicable principal
or interest funding subaccount, and applied to make monthly principal and
interest payments on those notes or reallocated or retained for the benefit of
senior classes of notes until the earlier of the date those notes are no longer
necessary to provide subordination protection for senior classes of notes or
until the legal maturity date of those notes.

    Any funds in the applicable principal funding subaccount that are not
reallocated to other classes of that series, any funds in the applicable
interest funding subaccount, and in the case of Class C notes, any funds in the
applicable Class C reserve account, will be available to pay principal of and
interest on that class of Notes. However, if your notes are Class B notes or
Class C notes, you generally will receive full payment of principal of those
notes only if and to the extent that, after giving effect to that payment, the
required subordinated amount will be maintained for the senior classes of notes
in that series. See "Risk Factors--Payment of Class B notes and Class C notes
may be delayed due to the subordination provisions."

    Following an event of default and acceleration, and on the applicable legal
maturity date, holders of notes will have the ability to direct a sale of
credit card receivables--or a sale of interests in credit card receivables--
held by the master trust only under the limited circumstances as described in
"Covenants, Events of Default and Early Redemption Events--Events of Default"
and "Deposit and Application of Funds--Sale of Credit Card Receivables." Even
if a sale of receivables is permitted, we can give no assurance that the
proceeds of the sale will be enough to pay unpaid principal of and interest on
the accelerated notes.

                                   THE ISSUER

    Citibank Credit Card Issuance Trust is the issuer of the notes. It is a
Delaware statutory business trust formed by Citibank (South Dakota) and
Citibank (Nevada) on September 12, 2000.

    The issuer exists for the exclusive purposes of:

  .   acquiring and holding the collateral certificate and other trust
      assets, including the proceeds of these assets;

  .   issuing series of notes;

  .   making payments on the notes; and

  .   engaging in other activities that are necessary or incidental to
      accomplish these limited purposes.

    The issuer is operated pursuant to a trust agreement among Citibank (South
Dakota), Citibank (Nevada) and The Bank of New York (Delaware), as trustee. The
issuer does not have any officers or directors. Its manager is Citibank (South
Dakota). As manager of the issuer, Citibank (South Dakota) will generally
direct the actions to be taken by the issuer.

    The assets of the issuer consist primarily of:

  .   the collateral certificate;

  .   derivative agreements that the issuer will enter into from time to
      time to manage interest rate or currency risk relating to some classes
      of notes; and

  .   the trust accounts.

The issuer does not expect to have any other significant assets.

The Owners

    Citibank (South Dakota), N.A. and Citibank (Nevada), National Association
are the sole owners of the beneficial interests in the issuer. Citibank (South
Dakota) and Citibank (Nevada) are sometimes referred to as the "Banks" in this
prospectus and the supplements to this prospectus. Other affiliates of the
Banks may in the future become owners of beneficial interests in the issuer.

    Citibank (South Dakota) is a national banking association and an indirect
wholly owned subsidiary of Citigroup Inc. It was formed in 1981 and conducts
nationwide consumer lending programs, primarily credit card-related activities.
Citibank (South Dakota) is the nation's largest bank credit card issuer. The
principal executive office of Citibank (South Dakota) is located at 701 East
60th Street, North, Sioux Falls, South Dakota 57117. Its telephone number is

                                USE OF PROCEEDS

    The issuer will pay the net proceeds from the sale of a class of notes to
Citibank (South Dakota) and Citibank (Nevada).

                                   THE NOTES

    The notes will be issued pursuant to the indenture. The indenture does not
limit the aggregate stated principal amount of notes that may be issued.

    The notes will be issued in series. Each series of notes is expected to
consist of Class A notes, Class B notes and Class C notes. Each class of notes
may have subclasses, if we so specify in a supplement to this prospectus, and
may be issued on different days. Whenever a "class" of notes is referred to in
this prospectus or any supplement to this prospectus, it also includes all
subclasses of that note, unless the context otherwise requires.

    The issuer may issue Class A notes, Class B notes and Class C notes of a
series at the same time or at different times, but no Class A notes or Class B
notes of a series may be issued unless a sufficient amount of subordinated
Class B notes and/or Class C notes of that series have previously been issued
and are outstanding. See "--Required Subordinated Amount." If and to the extent
specified in a supplement to this prospectus, the notes of a series may be
included in a group of series for purposes of sharing of principal collections
and/or finance charge collections.

    The issuer may offer notes denominated in any foreign currency. We will
describe the specific terms of any note denominated in a foreign currency in
the applicable supplement to this prospectus.

    If we specify in a supplement to this prospectus, the noteholders of a
particular class will have the benefit of a derivative agreement, including an
interest rate or currency swap, cap, collar, guaranteed investment contract or
other similar agreement for the exclusive benefit of that class. We will
describe any derivative agreement for the benefit of a class and the financial
institution that provides it in the applicable supplement to this prospectus.
Citibank (South Dakota), Citibank (Nevada) or any of their affiliates may be
counterparties to a derivative agreement.

    The issuer will pay principal of and interest on a class of notes solely
from the portion of finance charge collections and principal collections under
the collateral certificate which are available to that class of notes after
giving effect to all allocations and reallocations, amounts in any trust
account relating to that class of notes, and amounts received under any
derivative agreement relating to that class of notes. If those sources are not
sufficient to pay

                                       30
<PAGE>

the notes of that class, those noteholders will have no recourse to any other
assets of the issuer or any other person or entity for the payment of
principal of or interest on those notes.

    We will include the following terms of the notes in a supplement to this
prospectus:

  .   the series designation;

  .   whether the series is a single issuance series or a multiple issuance
      series;

  .   if the series will be part of a group of series for purposes of
      allocations and reallocations of principal collections and/or finance
      charge collections, the manner and extent to which each series in the
      group will participate in those allocations and reallocations;

  .   the stated principal amount of the notes and whether they are Class A
      notes, Class B notes or Class C notes or a subclass of any of those
      classes;

  .   the required subordinated amount, if any, for that class of notes;

  .   the currency of payment of principal of and interest on the notes, if
      other than U.S. dollars;

  .   the price or prices at which the notes will be issued;

  .   the expected principal payment date of the notes, which will be at
      least two years before the termination date of the collateral
      certificate;

  .   the legal maturity date of the notes, which will be no later than the
      termination date of the collateral certificate;

  .   the times at which the notes may, pursuant to any optional or
      mandatory redemption provisions, be redeemed, and the other terms and
      provisions of those redemption provisions;

Interest

    Each note, except zero-coupon discount notes, will bear interest at either
a fixed rate or a floating rate on its outstanding principal amount until final
payment of that note as described under "Deposit and Application of Funds--
Final Payment of the Notes." For each issuance of fixed rate notes, we will
designate in a supplement to this prospectus the fixed rate of interest at
which interest will accrue on that note. For each issuance of floating rate
notes, we will designate in a supplement to this prospectus the interest rate
index or other formula on which the interest is based. A discount note will be
issued at a price significantly lower than the stated principal amount payable
on that note's expected principal payment date. Until the expected principal
payment date for a discount note, accreted principal will be capitalized as
part of the principal of the note and reinvested in the collateral certificate.
The applicable supplement to this prospectus will specify the interest rate to
be borne by a discount note after an event of default or after its expected
principal payment date.

    Each payment of interest on a note will include all interest accrued from
the preceding interest payment date--or, for the first interest period, from
the issuance date--through the day preceding the current interest payment date,
or any other period as may be specified in a supplement to this prospectus. 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.

    If finance charge collections allocable to the collateral certificate are
less than expected, principal collections allocable to the subordinated classes
of notes under the collateral certificate may be used to pay interest on the
senior classes of notes of the same series. However, this reallocation of
principal would reduce the Invested Amount of the collateral certificate, as
well as the nominal liquidation amount of the subordinated classes of notes of
that series, and thus reduce later principal collections and finance charge
collections allocable to the collateral certificate, unless the principal
reduction is reimbursed from excess finance charge collections. See "Deposit
and Application of Funds--Allocation of Principal Collections to Accounts."

    If interest on a note is not paid within five business days after it is due
an event of default will occur with respect to that note. See "Covenants,
Events of Default and Early Redemption Events--Events of Default."

Principal

    The timing of payment of principal of a note will be specified in a
supplement to this prospectus.

    The issuer expects to pay the stated principal amount of each note in one
payment on that note's expected principal payment date, and the issuer is
obligated to do so if funds are available for that purpose. It is not an event
of default if the principal of a note is not paid on its expected principal
payment date because no funds are available for that purpose or because the
notes are required to provide subordination protection to a senior class of
notes of the same series.


                                       32
<PAGE>

    Principal of a note may be paid earlier than its expected principal payment
date if an early redemption event or an event of default occurs. See
"Covenants, Events of Default and Early Redemption Events--Early Redemption
Events" and "--Events of Default."

    Principal of a note may be paid later than its expected principal payment
date if sufficient funds are not allocable from the master trust to the
collateral certificate, or are not allocable under the collateral certificate
to the series and class of the note to be paid. Each note will have a legal
maturity date two years after its expected principal payment date. If the
stated principal amount of a note is not paid in full on its legal maturity
date, an event of default will occur with respect to that note. See "Covenants,
Events of Default and Early Redemption Events--Events of Default."

    See "Risk Factors--You may receive principal payments earlier or later than
the expected principal payment date" for a discussion of factors that may
affect the timing of principal payments on the notes.

Stated Principal Amount, Outstanding Dollar Principal Amount and Nominal
Liquidation Amount of Notes

    In order to understand the subordination of the different classes of notes
and the allocations of funds to different classes of notes, an investor needs
to understand three concepts:

  .   the stated principal amount of the notes;

  .   the outstanding dollar principal amount of the notes; and

  .   the nominal liquidation amount of the notes.

Each class of notes has a stated principal amount, an outstanding dollar
principal amount and a nominal liquidation amount.

  Stated Principal Amount

    The stated principal amount of a class of notes is the amount that is
stated on the face of the notes to be payable to the holder. It can be
denominated in U.S. dollars or in a foreign currency.

  Outstanding Dollar Principal Amount

    For U.S. dollar notes, the outstanding dollar principal amount will
initially be the same as the stated principal amount, less principal payments
to the noteholders. For foreign currency notes, the outstanding dollar
principal amount will be the U.S. dollar equivalent of the stated principal
amount of the notes, less dollar payments to derivative counterparties with
respect to principal. For discount notes, the outstanding dollar principal
amount will be an amount stated in, or determined by a formula described in,
the applicable supplement to this prospectus. The outstanding dollar principal
amount of a discount note will increase over

                                       33
<PAGE>

time as principal accretes, and the outstanding dollar principal amount of any
note will decrease as a result of each payment of principal of the note.

  Nominal Liquidation Amount

    The nominal liquidation amount of a class of notes is a U.S. dollar amount
based on the outstanding dollar principal amount of that class of notes, but
with some reductions--including reductions from reallocations of principal
collections and allocations of charge-offs of credit card receivables in the
master trust--and increases described under this heading. The aggregate nominal
liquidation amount of all of the notes will always be equal to the Invested
Amount of the collateral certificate, and the nominal liquidation amount of a
class of notes corresponds to the portion of the Invested Amount of the
collateral certificate that would be allocated to that class of notes if the
master trust were liquidated.

    In most circumstances, the nominal liquidation amount of a class of notes,
together with any funds on deposit in the applicable principal funding
subaccount, will be equal to the outstanding dollar principal amount of that
class. However, if there are reductions in the nominal liquidation amount of a
class of notes as a result of reallocations of principal collections from that
class to pay interest on senior classes, or as a result of charge-offs of
principal receivables in the master trust, there will be a deficit in the
nominal liquidation amount of that class. Unless that deficiency is reimbursed
through the reinvestment of Excess Finance Charge Collections in the collateral
certificate, the stated principal amount of some notes will not be paid in
full.

    The nominal liquidation amount is used to calculate the maximum amount of
funds that may be reallocated from a subordinated class of notes to pay
interest on a senior class of notes of the same series. The nominal liquidation
amount is also used to calculate the amount of principal collections that can
be allocated for payment to a class of notes, or paid to the counterparty to a
derivative agreement, if applicable. This means that if the nominal liquidation
amount of a class of notes has been reduced by charge-offs of principal
receivables in the master trust or by reallocations of principal collections to
pay interest on senior classes of notes, the holders of notes with the reduced
nominal liquidation amount may receive less than the full stated principal
amount of their notes, either because the amount of U.S. dollars allocated to
pay them is less than the outstanding dollar principal amount of the notes, or
because the amount of U.S. dollars allocated to pay the counterparty to a
derivative agreement is less than the amount necessary to obtain enough of the
applicable foreign currency for payment of their notes in full.

    The nominal liquidation amount of a class of notes may be reduced as
follows:

  .   If there are charge-offs of principal receivables in the master trust,
      the portion of charge-offs allocated to the collateral certificate
      will reduce the Invested Amount of the collateral certificate. The
      reduction allocated to the collateral certificate will then be
      reallocated among the series of notes pro rata based on the nominal
      liquidation amount of all notes in the series. Within each series, the
      reductions will initially be allocated pro rata to each class of notes
      based on the nominal

                                       34
<PAGE>

      liquidation amount of that class. Then, the reductions initially
      allocated to the Class A notes of that series will be reallocated,
      first, to the Class C notes of that series, and second, to the Class B
      notes of that series. The reductions initially allocated to the Class
      B notes of that series will be reallocated to the Class C notes of
      that series.

     However, these reallocations will be made from a senior class to a
     subordinated class only to the extent that the senior class has not
     used all of its required subordinated amount. For a single issuance
     series, the subordination usage limit is the same as the limit
     described in "Deposit and Application of Funds--Limit on Reallocation
     of Principal Collections from Subordinated Classes to Senior Classes
     of Single Issuance Series." For multiple issuance series, the
     subordination usage limit is the same as the limit described in
     "Deposit and Application of Funds--Limit on Reallocation of Principal
     Collections from Subordinated Classes to Senior Classes of Multiple
     Issuance Series." Reductions that cannot be reallocated to a
     subordinated class will reduce the nominal liquidation amount of the
     class to which the reductions were initially allocated.

  .   If principal collections are allocated from a subordinated class of
      notes of a series to pay interest on the senior classes of notes of
      that series, the nominal liquidation amount of that subordinated class
      will be reduced by the amount of the reallocations. The amount of the
      reallocation of principal collections to pay interest on Class A notes
      will be applied first, to reduce the nominal liquidation amount of
      Class C notes of the same series to the extent of the required
      subordinated amount of Class C notes for that class of Class A notes,
      and second, to reduce the nominal liquidation amount of Class B notes
      of the same series to the extent of the required subordinated amount
      of Class B notes for that class of Class A notes. The amount of the
      reallocation of principal collections to pay interest on Class B notes
      will be applied to reduce the nominal liquidation amount of Class C
      notes of the same series to be extent of the required subordination
      amount of Class C notes for that class of Class B notes. No principal
      of Class A notes may be reallocated to pay interest on any class of
      notes. In a multiple issuance series, these reductions will be
      allocated to each outstanding subclass of the series, based on the
      nominal liquidation amount of each subclass.

  .   The nominal liquidation amount of a class of notes will be reduced by
      the amount on deposit in its principal funding subaccount after giving
      effect to all allocations, reallocations and payments. This includes
      principal collections that are deposited directly into that class's
      principal funding subaccount, or reallocated from the principal
      funding subaccount for a subordinated class.

  .   The nominal liquidation amount of a class of notes will be reduced by
      the amount of all payments of principal of that class.

  .   If a class of notes directs a sale of credit card receivables after an
      event of default and acceleration or on its legal maturity date, its
      nominal liquidation amount is automatically reduced to zero. See
      "Deposit and Application of Funds--Sale of Credit Card Receivables."

                                       35
<PAGE>

    There are three ways in which the nominal liquidation amount of a note can
be increased.

  .   For a class of discount notes, the nominal liquidation amount of that
      class will increase over time as principal accretes, to the extent
      that finance charge collections are allocated to that class for that
      purpose.

  .   If Excess Finance Charge Collections are available, they will be
      applied to reimburse earlier reductions in nominal liquidation amount
      from charge-offs of principal receivables in the master trust, or from
      reallocations of principal collections from subordinated classes to
      pay interest on senior classes. These reimbursements will be allocated
      to each series pro rata based on the sum of all unreimbursed
      reductions of each class in that series. Within each series, the
      increases will be allocated first, to any Class A notes with a
      deficiency in their nominal liquidation amount, second, to any Class B
      notes with a deficiency in their nominal liquidation amount, and
      third, to any Class C notes with a deficiency in their nominal
      liquidation amounts. In multiple issuance series, the increases will
      be allocated to each subclass of a class pro rata based on the
      deficiency in the nominal liquidation amount in each subclass.

  .   If principal collections have been reallocated from the principal
      funding subaccount for a subordinated class to the principal funding
      subaccount for a senior class of notes of the same series, the nominal
      liquidation amount of the subordinated class will be increased by the
      amount of the reallocation, and the nominal liquidation amount of the
      senior class will be reduced by the same amount.

    If the nominal liquidation amount of your notes has been reduced by charge-
offs of principal receivables in the master trust and reallocations of
principal collections to pay interest on senior classes of notes, and the
reduction has not been reimbursed from Excess Finance Charge Collections, you
will likely not receive repayment of all of your principal. See "Deposit and
Application of Funds--Final Payment of the Notes."

    The nominal liquidation amount of a class of notes may not be reduced below
zero, and may not be increased above the outstanding dollar principal amount of
that class of notes, less any amounts on deposit in the applicable principal
funding subaccount.

    If a note held by the Banks, the issuer or any of their affiliates is
canceled, the nominal liquidation amount of that note is automatically reduced
to zero, with a corresponding automatic reduction in the Invested Amount of the
collateral certificate.

    For a single issuance series, the cumulative amount of reductions of the
nominal liquidation amount of any class of notes due to reallocation of
principal collections to pay interest on senior classes of notes and charge-
offs of principal receivables in the master trust cannot exceed the outstanding
dollar principal amount of that class. See "Deposit and Application of Funds--
Limit on Reallocations of Principal Collections from Subordinated Classes to
Senior Classes of Single Issuance Series."


                                       36
<PAGE>

    For Class B notes and Class C notes of a multiple issuance series, the
reductions in the nominal liquidation amount due to reallocation of principal
collections to pay interest on senior classes of notes and charge-offs of
principal receivables in the master trust may be allocated to a subclass of
Class C notes and Class B notes only to the extent that subordination of that
series is available. Subordination is limited so that no senior class of notes
can utilize more than its required subordinated amount of subordinated classes
of notes of the same series as described in "Deposit and Application of Funds--
Limit on Reallocations of Principal Collections from Subordinated Classes to
Senior Classes of Multiple Issuance Series."

    Because reductions to the nominal liquidation amount are limited as
described in the prior two paragraphs, it is possible that the nominal
liquidation amount of a subordinated class will be greater than zero, but no
further reductions will be allocated to that class, and any further reductions
will be allocated to the next senior class in that series. This can occur, for
example, when the nominal liquidation amount of a class of Class C notes of a
series has been reduced to zero as a result of the allocation of charge-offs of
principal receivables in the master trust to that class and the reallocation of
principal collections from that class to pay interest on senior classes of
notes, but the reduction in the Class C nominal liquidation amount is later
reimbursed from Excess Finance Charge Collections. Because the Class C nominal
liquidation amount has been reduced to zero, the Class A notes and Class B
notes of that series have received the full benefit of the subordination of the
Class C notes, and no further reductions will be allocated to the Class C
notes, even if the Class C notes later have a positive nominal liquidation
amount from reimbursements. However, in the case of multiple issuance series,
reimbursements of reductions in the nominal liquidation amount of subordinated
classes of notes may be counted toward the required subordinated amount of
senior classes of that series, but only for subclasses that are issued after
the date of that reimbursement. See "--Subordination of Principal."

    Allocations of charge-offs of principal receivables in the master trust and
reallocations of principal collections to senior classes of notes reduce the
nominal liquidation amount of outstanding notes only, and do not affect notes
that are issued after that time.

Subordination of Principal

    Principal payments on Class B notes and Class C notes of a series are
subordinated to payments on Class A notes of that series. Subordination of
Class B notes and Class C notes of a series provides credit enhancement for
Class A notes of that series.

    Principal payments on Class C notes of a series are subordinated to
payments on Class A notes and Class B notes of that series. Subordination of
Class C notes of a series provides credit enhancement for the Class A notes and
Class B notes of that series.

    In all series, principal collections that are allocable to subordinated
classes of notes may be reallocated to pay interest on senior classes of notes
of that series. In addition, losses of charged-off receivables in the master
trust are allocated first to the subordinated classes of a series. See "The
Notes--Stated Principal Amount, Outstanding Dollar Principal Amount and

                                       37
<PAGE>

Nominal Liquidation Amount--Nominal Liquidation Amount" and "Deposit and
Application of Funds--Allocation of Principal Collections to Accounts."

    In a single issuance series, no principal payments will be made on a
subordinated class of notes of that series until all principal of the senior
classes of notes of that series has been paid in full. However, there are
several exceptions to this rule. Principal may be paid to the holders of
subordinated classes while notes of senior classes of that series are still
outstanding under the following circumstances:

  .   If the nominal liquidation amount of a subordinated class has been
      reduced as a result of an allocation of charge-offs of principal
      receivables to that class or reallocation of principal collections
      from that class to pay interest on a senior class, and that reduction
      is later reimbursed from Excess Finance Charge Collections, the amount
      of that reimbursement is no longer subordinated to the senior classes
      of that series and may be paid to the holders of the subordinated
      class while those notes of senior classes are still outstanding.

  .   If the principal funding subaccounts for the senior classes of notes
      of a series have been prefunded as described in "Deposit and
      Application of Funds--Targeted Deposits of Principal Collections to
      the Principal Funding Account--Prefunding of the Principal Funding
      Account for Senior Classes," the subordinated classes of notes of that
      series may be paid.

  .   Class C notes may be paid with funds available from the applicable
      Class C reserve subaccount. See "Deposit and Application of Funds--
      Withdrawals from the Class C Reserve Account."

    In a multiple issuance series, payment of principal may be made on a
subordinated class of notes of that series before payment in full of each
senior class of notes of that series but only under the following
circumstances:

  .   If after giving effect to the proposed principal payment there is
      still a sufficient principal amount of subordinated notes to support
      the outstanding senior notes of that series. See "Deposit and
      Application of Funds--Limit on Repayment of Multiple Issuance Series."
      For example, if a subclass of Class A notes has matured and been
      repaid, this generally means that at least some Class B notes and
      Class C notes may be repaid, even if other subclasses of Class A notes
      are outstanding and require reallocation of principal collections from
      subordinated classes.

  .   If the nominal liquidation amount of a subordinated class has been
      reduced as a result of allocation of charge-offs of principal
      receivables in the master trust to that class or reallocation of
      principal collections from that class to pay interest on a senior
      class, and that reduction is later reimbursed from Excess Finance
      Charge Collections, then the amount of that reimbursement is no longer
      subordinated to the senior classes of notes of that series that were
      outstanding before the date of reimbursement and may be paid to the
      holders of the subordinated class while those notes of senior classes
      are still outstanding. However, that reimbursed

                                       38
<PAGE>

      amount of a subordinated class of notes is subordinated to the senior
      classes of notes that are issued on or after the date of the
      reimbursement.

  .   Subordinated classes of notes of a multiple issuance series may be
      paid before senior classes of notes of that series if the principal
      funding subaccounts for the senior classes of notes have been
      prefunded as described in "Deposit and Application of Funds--Targeted
      Deposits of Principal Collections to the Principal Funding Account--
      Prefunding of the Principal Funding Account for Senior Classes," and
      Class C notes may be paid with funds available from the applicable
      Class C reserve subaccount. See "Deposit and Application of Funds--
      Withdrawals from the Class C Reserve Account."

  .   On the legal maturity date of a subordinated class of notes, funds on
      deposit in that class's principal funding subaccount will be paid to
      the subordinated noteholders. As a result, there could be senior
      classes of that series that remain outstanding without the required
      subordination protection.

    The payment of accrued interest on a class of notes of a series from
finance charge collections is not senior to or subordinated to payment of
interest on any other class of notes of that series. However, in the case of a
discount note, the accreted principal of that note corresponding to
capitalized interest will be senior or subordinated to the same extent that
principal is senior or subordinated.

Redemption and Early Redemption of Notes

    Each class of notes will be subject to mandatory redemption on its
expected principal payment date, which will be two years before its legal
maturity date.

    If we so specify in a supplement to this prospectus the issuer may, at its
option, redeem the notes of any class before its expected principal payment
date. The supplement will indicate at what times the issuer may exercise that
right of redemption and if the redemption may be made in whole or in part as
well as any other terms of the redemption. The issuer will give notice to
holders of the affected notes before any optional redemption date.

    If we so specify in a supplement to this prospectus a noteholder may, at
its option, require the issuer to redeem notes before the expected principal
payment date. The supplement will indicate at what times a noteholder may
exercise that right of redemption and if the redemption may be made in whole
or in part as well as any other terms of the redemption.

    In addition, if an early redemption event occurs, the issuer will be
required to redeem each class of affected notes before the note's expected
principal payment date to the extent funds are available for that purpose. The
issuer will give notice to holders of the affected notes before an early
redemption date. See "Covenants, Events of Default and Early Redemption
Events--Early Redemption Events" for a description of the early redemption
events and their consequences to holders of notes.


                                      39
<PAGE>

    Whenever the issuer is required to redeem a class of notes before its legal
maturity date, it will do so only if funds are allocated to the collateral
certificate and to that class of notes, and only to the extent that the class
of notes to be redeemed is not required to provide required subordinated amount
to a senior class of notes. A noteholder will have no claim against the issuer
if the issuer fails to make a required redemption of notes because no funds are
available for that purpose or because the notes to be redeemed are required to
provide subordination protection to a senior class of notes. The failure to
redeem before the legal maturity date under these circumstances will not be an
event of default.

Issuances of New Series, Classes and Subclasses of Notes

  Conditions to Issuance

    The issuer may issue new series, classes and subclasses of notes, so long
as the conditions of issuance are met. These conditions include:

     --  the legal maturity date of the new issuance is no more than
         fourteen years after the date of issuance; and

     --  any other conditions specified by a rating agency to the issuer in
         writing,

     or the issuer obtains confirmation from the rating agencies that the
     new issuance of notes will not cause a reduction or withdrawal of the
     rating of any outstanding notes rated by that rating agency;

  .   at the time of the new issuance, either the ratings condition
      described in "Prospectus Summary--Ratings" is satisfied or the issuer
      obtains confirmation from the rating agencies that the new issuance of
      notes will not cause a reduction or withdrawal of the rating of any
      outstanding notes rated by that rating agency;

  .   no early amortization event with respect to the collateral certificate
      has occurred and is continuing as of the date of the new issuance;

                                       41
<PAGE>

  .   if the new issuance results in an increase in the funding deficit of
      the Class C reserve account for any subclass of Class C notes of a
      multiple issuance series, the issuer makes a cash deposit to that
      Class C reserve account in the amount of that increase; and

  .   any other conditions specified in any supplement to this prospectus
      are satisfied.

  Required Subordination Protection in Multiple Issuance Series

    No Class A notes or Class B notes of a multiple issuance series may be
issued unless the required subordinated amount of subordinated classes for that
class of notes is available at the time of its issuance, as described in the
following two paragraphs.

    In order to issue Class A notes of a multiple issuance series, the issuer
must calculate the available amount of Class B notes and Class C notes of that
series. The issuer will first calculate the subordinated amount of Class B
notes required for Class A notes. This is done by computing the following:

  .   the aggregate nominal liquidation amount of all outstanding Class B
      notes of that series on that date, plus all funds on deposit in the
      principal funding subaccounts for Class B notes of that series--other
      than receivables sales proceeds in those subaccounts--on that date,
      after giving effect to issuances, deposits, allocations or payments
      with respect to Class B notes to be made on that date;

  .   minus, the aggregate amount of the Class A required subordinated
      amount of Class B notes for all other Class A notes of that series
      which are outstanding on that date after giving effect to any
      issuances or repayments in full of any Class A notes to be made on
      that date; and

  .   plus, the amount of usage by outstanding Class A notes of Class B
      required subordinated amount, as described in "Deposit and Application
      of Funds--Limit on Allocation of Principal Collections from
      Subordinated Classes to Senior Classes of Multiple Issuance Series."

    The calculation in the prior paragraph will also be made in the same manner
for calculating the subordinated amount of Class C notes required for Class A
notes and the subordinated amount of Class C notes required for Class B notes.

Required Subordinated Amount

    The required subordinated amount of a senior class of notes of a multiple
issuance series means the amount of a subordinated class that is required to be
outstanding on the date when the senior class of notes is issued to provide
subordination protection for that

                                       42
<PAGE>

senior class. It is also used to determine whether a subordinated class of a
multiple issuance series of notes may be repaid before the legal maturity date
while senior classes of notes of that series are outstanding.

    Unless specified otherwise in the applicable supplement to this prospectus
for a series of notes, on the date of issuance of Class A notes of a multiple
issuance series, the required subordinated amount for Class B notes will be
5.98291% and for Class C notes 7.97721%, in each case expressed as a percentage
of the initial outstanding dollar principal amount of Class A notes, and on the
date of issuance of Class B notes of a multiple issuance series, the required
subordinated amount for Class C notes will be 133.33333%, expressed as a
percentage of the initial outstanding dollar principal amount of Class B notes.
For discount notes of a senior class, the method of calculating the required
subordinated amount will be set forth in the applicable supplement to this
prospectus.

    The issuer may change the amount of required or available subordination
available for any class of notes of a multiple issuance series, or the method
of computing the amount of that subordination, at any time without the consent
of any noteholders so long as the issuer has received

  .   confirmation from the rating agencies that have rated any outstanding
      notes of that series that the change will not result in the rating
      assigned to any outstanding notes in that series to be withdrawn or
      reduced;

  .   an opinion of counsel that for federal and South Dakota income and
      franchise tax purposes (1) the change will not adversely affect the
      characterization as debt of any outstanding series or class of
      investor certificates issued by the master trust, other than the
      collateral certificate, (2) the change will not cause a taxable event
      to holders of master trust investor certificates, and (3) following
      the change, the master trust will not be an association, or publicly
      traded partnership, taxable as a corporation; and

  .   an opinion of counsel that for federal and Delaware income and
      franchise tax purposes (1) the change will not adversely affect the
      characterization of the notes of any outstanding series or class as
      debt, (2) the change will not cause a taxable event to holders of any
      outstanding notes, and (3) following the change, the issuer will not
      be an association, or publicly traded partnership, taxable as a
      corporation.

Payments on Notes; Paying Agent

    The notes offered by this prospectus will be issued in book-entry form and
payments of principal of and interest on the notes will be made in U.S. dollars
as described under "--Book-Entry Notes" unless the stated principal amount of
the notes is denominated in a foreign currency.

    The issuer and the indenture trustee, and any agent of the issuer or the
indenture trustee, will treat the registered holder of any note as the absolute
owner of that note, whether or not the note is overdue and notwithstanding any
notice to the contrary, for the purpose of making payment and for all other
purposes.


                                       43
<PAGE>

    The issuer will make payments on a note to the registered holder of the
note at the close of business on the record date established for the related
payment date.

    The issuer has designated the corporate trust office of Citibank, N.A., in
New York City, as its paying agent for the notes of each series. The issuer
will identify any other entities appointed to serve as paying agents on notes
of a series or class in a supplement to this prospectus. The issuer may at any
time designate additional paying agents or rescind the designation of any
paying agent or approve a change in the office through which any paying agent
acts. However, the issuer will be required to maintain a paying agent in each
place of payment for a series or class of notes.

    After notice by publication, all funds paid to a paying agent for the
payment of the principal of or interest on any note of any series which remains
unclaimed at the end of two years after the principal or interest becomes due
and payable will be repaid to the issuer. After funds are repaid to the issuer,
the holder of that note may look only to the issuer for payment of that
principal or interest.

Denominations

    The notes offered by this prospectus will be issued in denominations of
$1,000 and multiples of $1,000 in excess of that amount.

Record Date

    The record date for payment of the notes will be the last day of the month
before the related payment date.

Governing Law

    The laws of the State of New York will govern the notes and the indenture.

Form, Exchange, and Registration and Transfer of Notes

    The notes offered by this prospectus will be issued in registered form. The
notes will be represented by one or more global notes registered in the name of
The Depository Trust Company, as depository, or its nominee. We refer to each
beneficial interest in a global note as a "book-entry note." For a description
of the special provisions that apply to book-entry notes, see "--Book-Entry
Notes."

    A holder of notes may exchange those notes for other notes of the same
class of any authorized denominations and of the same aggregate stated
principal amount and tenor.

                                       44
<PAGE>

    Any holder of a note may present that note for registration of transfer,
with the form of transfer properly executed, at the office of the note
registrar or at the office of any transfer agent that the issuer designates.
Holders of notes will not be charged any service charge for the exchange or
transfer of their notes. Holders of notes that are to be transferred or
exchanged will be liable for the payment of any taxes and other governmental
charges described in the indenture before the transfer or exchange will be
completed. The note registrar or transfer agent, as the case may be, will
effect a transfer or exchange when it is satisfied with the documents of title
and identity of the person making the request.

    The issuer has appointed Citibank, N.A. as the note registrar for the
notes. The issuer also may at any time designate additional transfer agents for
any series or class of notes. The issuer may at any time rescind the
designation of any transfer agent or approve a change in the location through
which any transfer agent acts. However, the issuer will be required to maintain
a transfer agent in each place of payment for a series or class of notes.

Book-Entry Notes

    The notes offered by this prospectus will be in book-entry form. This means
that, except under the limited circumstances described in this subheading under
"Definitive Notes," purchasers of notes will not be entitled to have the notes
registered in their names and will not be entitled to receive physical delivery
of the notes in definitive paper form. Instead, upon issuance, all the notes of
a class will be represented by one or more fully registered permanent global
notes, without interest coupons.

    Each global note will be deposited with a securities depository named The
Depository Trust Company and will be registered in the name of its nominee,
Cede & Co. No global note representing book-entry notes may be transferred
except as a whole by DTC to a nominee of DTC, or by a nominee of DTC to another
nominee of DTC. Thus, DTC or its nominee will be the only registered holder of
the notes and will be considered the sole representative of the beneficial
owners of notes for purposes of the indenture.

    The registration of the global notes in the name of Cede & Co. will not
affect beneficial ownership and is performed merely to facilitate subsequent
transfers. The book-entry system, which is also the system through which most
publicly traded common stock is held, is used because it eliminates the need
for physical movement of securities. The laws of some jurisdictions, however,
may require some purchasers to take physical delivery of their notes in
definitive form. These laws may impair the ability to transfer book-entry
notes.

    Purchasers of notes in the United States can hold interests in the global
notes only through DTC, either directly, if they are participants in that
system--such as a bank, brokerage house or other institution that maintains
securities accounts for customers with DTC or its nominee--or otherwise
indirectly through a participant in DTC. Purchasers of

                                       45
<PAGE>

notes in Europe can hold interests in the global notes only through
Clearstream, Luxembourg, or through Morgan Guaranty Trust Company of New York,
Brussels Office, as operator of the Euroclear system.

    Because DTC will be the only registered owner of the global notes,
Clearstream, Luxembourg and Euroclear will hold positions through their
respective U.S. depositories, which in turn will hold positions on the books of
DTC. Citibank, N.A. will act as U.S. depository for Clearstream, Luxembourg,
and The Chase Manhattan Bank will act as U.S. depository for Euroclear.

    As long as the notes are in book-entry form, they will be evidenced solely
by entries on the books of DTC, its participants and any indirect participants.
DTC will maintain records showing

  .   the ownership interests of its participants, including the U.S.
      depositories; and

  .   all transfers of ownership interests between its participants.

The participants and indirect participants, in turn, will maintain records
showing

  .   the ownership interests of their customers, including indirect
      participants, that hold the notes through those participants; and

  .   all transfers between these persons.

Thus, each beneficial owner of a book-entry note will hold its note indirectly
through a hierarchy of intermediaries, with DTC at the "top" and the beneficial
owner's own securities intermediary at the "bottom."

    The issuer, the indenture trustee and their agents will not be liable for
the accuracy of, and are not responsible for maintaining, supervising or
reviewing DTC's records or any participant's records relating to book-entry
notes. The issuer, the indenture trustee and their agents also will not be
responsible or liable for payments made on account of the book-entry notes.

    Until definitive notes are issued to the beneficial owners as described in
this subheading under "Definitive Notes," all references to "holders" of notes
means DTC. The issuer, the indenture trustee and any paying agent, transfer
agent or securities registrar may treat DTC as the absolute owner of the notes
for all purposes.

    Beneficial owners of book-entry notes should realize that the issuer will
make all distributions of principal and interest on their notes to DTC and will
send all required reports and notices solely to DTC as long as DTC is the
registered holder of the notes. DTC and the participants are generally required
by law to receive and transmit all distributions, notices and directions from
the indenture trustee to the beneficial owners through the chain of
intermediaries.


                                       46
<PAGE>

    Similarly, the indenture trustee will accept notices and directions solely
from DTC. Therefore, in order to exercise any rights of a holder of notes under
the indenture, each person owning a beneficial interest in the notes must rely
on the procedures of DTC and, in some cases, Clearstream, Luxembourg or
Euroclear. If the beneficial owner is not a participant in that system, then it
must rely on the procedures of the participant through which that person owns
its interest. DTC has advised the issuer that it will take actions under the
indenture only at the direction of its participants, which in turn will act
only at the direction of the beneficial owners. Some of these actions, however,
may conflict with actions it takes at the direction of other participants and
beneficial owners.

    Notices and other communications by DTC to participants, by participants to
indirect participants, and by participants and indirect participants to
beneficial owners will be governed by arrangements among them.

    Beneficial owners of book-entry notes should also realize that book-entry
notes may be more difficult to pledge because of the lack of a physical note.
Beneficial owners may also experience delays in receiving distributions on
their notes since distributions will initially be made to DTC and must be
transferred through the chain of intermediaries to the beneficial owner's
account.

  The Depository Trust Company

    DTC is a limited-purpose trust company organized under the New York Banking
Law and is a "banking institution" within the meaning of the New York Banking
Law. DTC is also 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 Section 17A of the Securities Exchange Act
of 1934. DTC was created to hold securities deposited by its participants and
to facilitate the clearance and settlement of securities transactions among its
participants through electronic book-entry changes in accounts of the
participants, thus eliminating the need for physical movement of securities.
DTC is owned by a number of its participants and by the New York Stock
Exchange, Inc., the American Stock Exchange, Inc., and the National Association
of Securities Dealers, Inc. The rules applicable to DTC and its participants
are on file with the Securities and Exchange Commission.

  Clearstream, Luxembourg

    Clearstream, Luxembourg is registered as a bank in Luxembourg and is
regulated by the Banque Centrale du Luxembourg, the Luxembourg Central Bank,
which supervises Luxembourg banks. Clearstream, Luxembourg holds securities for
its customers and facilitates the clearance and settlement of securities
transactions by electronic book-entry transfers between their accounts.
Clearstream, Luxembourg provides various services, including safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. Clearstream, Luxembourg also deals with
domestic securities markets in over 30 countries through established depository
and custodial relationships. Clearstream, Luxembourg has established an
electronic bridge with Euroclear

                                       47
<PAGE>

in Brussels to facilitate settlement of trades between Clearstream, Luxembourg
and Euroclear. Clearstream, Luxembourg currently accepts over 110,000
securities issues on its books.

    Clearstream, Luxembourg's customers are worldwide financial institutions
including underwriters, securities brokers and dealers, banks, trust companies
and clearing corporations. Clearstream, Luxembourg's U.S. customers are limited
to securities brokers and dealers, and banks. Currently, Clearstream,
Luxembourg has approximately 2,000 customers located in over 80 countries,
including all major European countries, Canada, and the United States. Indirect
access to Clearstream, Luxembourg is available to other institutions that clear
through or maintain a custodial relationship with an account holder of
Clearstream, Luxembourg.

  Euroclear System

    Euroclear was created in 1968 to hold securities for participants of
Euroclear and to clear and settle transactions between Euroclear participants
through simultaneous electronic book-entry delivery against payment. This
system eliminates the need for physical movement of securities and any risk
from lack of simultaneous transfers of securities and cash. Euroclear includes
various other services, including securities lending and borrowing and
interfaces with domestic markets in several countries. The Euroclear Operator
is the Brussels, Belgium office of Morgan Guaranty Trust Company of New York,
under contract with Euro-clear Clearance Systems S.C., a Belgian cooperative
corporation, known as the "Cooperative." The Euroclear Operator conducts all
operations. All Euroclear securities clearance accounts and Euroclear cash
accounts are accounts with the Euroclear Operator, not the Cooperative. The
Cooperative establishes policy for Euroclear on behalf of Euroclear
participants. Euroclear participants include banks, including central banks,
securities brokers and dealers and other professional financial intermediaries
and may include the underwriters. Indirect access to Euroclear is also
available to other firms that clear through or maintain a custodial
relationship with a Euroclear participant, either directly or indirectly.

    The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. For this
reason, it is regulated and examined by the Board of Governors of the Federal
Reserve System and the New York State Banking Department, as well as the
Belgian Banking Commission.

    Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian
law. These Terms and Conditions govern transfers of securities and cash within
Euroclear, withdrawals of securities and cash from Euroclear, and receipts of
payments with respect to securities in Euroclear. All securities in Euroclear
are held on a fungible basis without attribution of specific securities to
specific securities clearance accounts. The Euroclear Operator acts under the
Terms and Conditions only on behalf of Euroclear participants, and has no
record of or relationship with persons holding through Euroclear participants.

provided by each of them for informational purposes only and is not intended to

  Distributions on Book-Entry Notes

    The issuer will make distributions of principal of and interest on book-
entry notes to DTC. These payments will be made in immediately available funds
by the issuer's paying agent, Citibank, N.A., at the office of the paying agent
in New York City that the issuer designates for that purpose.

    In the case of principal payments, the global notes must be presented to
the paying agent in time for the paying agent to make those payments in
immediately available funds in accordance with its normal payment procedures.

    Upon receipt of any payment of principal of or interest on a global note,
DTC will immediately credit the accounts of its participants on its book-entry
registration and transfer system. DTC will credit those accounts with payments
in amounts proportionate to the participants' respective beneficial interests
in the stated principal amount of the global note as shown on the records of
DTC. Payments by participants to beneficial owners of book-entry notes will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in "street name," and will be the responsibility of those participants.

    Distributions on book-entry notes held beneficially through Clearstream,
Luxembourg will be credited to cash accounts of Clearstream, Luxembourg
participants in accordance with its rules and procedures, to the extent
received by its U.S. depository.

    Distributions on book-entry notes held beneficially through Euroclear will
be credited to the cash accounts of Euroclear participants in accordance with
the Terms and Conditions, to the extent received by its U.S. depository.

    In the event definitive notes are issued, distributions of principal and
interest on definitive notes will be made directly to the holders of the
definitive notes in whose names the definitive notes were registered at the
close of business on the related record date.

  Global Clearance and Settlement Procedures

    Initial settlement for the notes will be made in immediately available
funds. Secondary market trading between DTC participants will occur in the
ordinary way in accordance with DTC's rules and will be settled in immediately
available funds using DTC's Same-Day Funds Settlement System. Secondary market
trading between Clearstream, Luxembourg participants and/or Euroclear
participants will occur in the ordinary way in accordance with the applicable
rules and operating procedures of Clearstream, Luxembourg and Euroclear and
will be settled using the procedures applicable to conventional eurobonds in
immediately available funds.


                                       49
<PAGE>

    Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Clearstream,
Luxembourg or Euroclear participants, on the other, will be effected in DTC in
accordance with DTC's rules on behalf of the relevant European international
clearing system by the U.S. depositories. However, cross-market transactions of
this type will require delivery of instructions to the relevant European
international clearing system by the counterparty in that system in accordance
with its rules and procedures and within its established deadlines, European
time. The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to its U.S.
depository to take action to effect final settlement on its behalf by
delivering or receiving notes in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to
DTC. Clearstream, Luxembourg participants and Euroclear participants may not
deliver instructions directly to DTC.

    Because of time-zone differences, credits to notes received in Clearstream,
Luxembourg or Euroclear as a result of a transaction with a DTC participant
will be made during subsequent securities settlement processing and will be
credited the business day following a DTC settlement date. The credits to or
any transactions in the notes settled during processing will be reported to the
relevant Euroclear or Clearstream, Luxembourg participants on that business
day. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales
of notes by or through a Clearstream, Luxembourg participant or a Euroclear
participant to a DTC participant will be received with value on the DTC
settlement date, but will be available in the relevant Clearstream, Luxembourg
or Euroclear cash account only as of the business day following settlement in
DTC.

    Although DTC, Clearstream, Luxembourg and Euroclear have agreed to these
procedures in order to facilitate transfers of notes among participants of DTC,
Clearstream, Luxembourg and Euroclear, they are under no obligation to perform
or continue to perform these procedures and these procedures may be
discontinued at any time.

  Definitive Notes

    Beneficial owners of book-entry notes may exchange those notes for
definitive notes registered in their name only if:

  .   DTC is unwilling or unable to continue as depository for the global
      notes or ceases to be a registered "clearing agency" and the issuer is
      unable to find a qualified replacement for DTC;

  .   the issuer, in its sole discretion, elects to terminate the book-entry
      system through DTC; or

  .   any event of default has occurred with respect to those book-entry
      notes, and beneficial owners evidencing not less than 50% of the
      unpaid outstanding dollar principal amount of the notes of that class
      advise the indenture trustee and DTC that the continuation of a book
      entry system is no longer in the best interests of those beneficial
      owners.

                                       50
<PAGE>

    If any of these three events occurs, DTC is required to notify the
beneficial owners through the chain of intermediaries that the definitive notes
are available. The appropriate global note will then be exchangeable in whole
for definitive notes in registered form of like tenor and of an equal aggregate
stated principal amount, in specified denominations. Definitive notes will be
registered in the name or names of the person or persons specified by DTC in a
written instruction to the registrar of the notes. DTC may base its written
instruction upon directions it receives from its participants. Thereafter, the
holders of the definitive notes will be recognized as the "holders" of the
notes under the indenture.

Replacement of Notes

    The issuer will replace at the expense of the holder any mutilated note,
upon surrender of that note to the indenture trustee. The issuer will replace
at the expense of the holder any notes that are destroyed, lost or stolen upon
delivery to the indenture trustee of evidence of the destruction, loss or theft
of those notes satisfactory to the issuer and the indenture trustee. In the
case of a destroyed, lost or stolen note, the issuer and the indenture trustee
may require the holder of the note to provide an indemnity satisfactory to the
indenture trustee and the issuer before a replacement note will be issued.

Acquisition and Cancellation of Notes by the Issuer and the Banks

    The issuer, the Banks and their affiliates may acquire notes in the open
market or otherwise.

    The issuer, the Banks and their affiliates may cause the notes acquired by
them to be canceled and notes so canceled will no longer be outstanding.
However, any cancellation of notes will observe the same limitations for
payments of subordinated classes as described in "Deposit and Application of
Funds--Limit on Repayments of Subordinated Classes of Single Issuance Series"
and "--Limit on Repayments of Subordinated Classes of Multiple Issuance
Series."

                       SOURCES OF FUNDS TO PAY THE NOTES

The Collateral Certificate

    The primary source of funds for the payment of principal of and interest on
the notes is the collateral certificate issued by the master trust to the
issuer. For a description of the master trust and its assets, see "The Master
Trust." The collateral certificate is the only master trust investor
certificate issued pursuant to Series 2000 of the master trust certificates.

    Finance charge collections allocated to the collateral certificate will be
deposited every month by the master trust into the issuer's collection account.
Finance charge collections allocated to the collateral certificate are not
shared with or reallocated to any other series of investor certificates issued
by the master trust.

    Each month, the issuer will request the master trust to deposit into the
collection account the amount of principal collections the issuer needs to
reallocate to the interest

                                       51
<PAGE>

funding account and for deposits into the principal funding account. To the
extent principal collections are allocable to the collateral certificate, the
master trust will deposit the requested amount of principal collections into
the collection account.

    The collateral certificate represents an undivided interest in the assets
of the master trust. The assets of the master trust consist primarily of credit
card receivables arising in selected MasterCard and VISA* revolving credit card
accounts that have been transferred by the Banks. The amount of credit card
receivables in the master trust will fluctuate from day to day as new
receivables are generated or added to or removed from the master trust and as
other receivables are collected, charged off as uncollectible, or otherwise
adjusted.

    The collateral certificate has a fluctuating Invested Amount, representing
the investment of that certificate in credit card receivables. The Invested
Amount of the collateral certificate will be the same as the total nominal
liquidation amount of the outstanding notes. For a discussion of Invested
Amount, see "Invested Amount" in the glossary.

    The collateral certificate has no specified interest rate. The issuer, as
holder of the collateral certificate, is entitled to receive its allocable
share of cash collections from two kinds of credit card receivables payable to
the master trust: finance charge receivables and principal receivables.

    Finance charge receivables are all periodic finance charges, annual
membership fees, cash advance fees and late charges on amounts charged for
merchandise and services, interchange, which is described below in this
paragraph, and some other fees designated by the Banks. Principal receivables
are all amounts charged by cardholders for merchandise and services, amounts
advanced to cardholders as cash advances and all other fees billed to
cardholders on the credit card accounts. Recoveries of charged-off receivables
are credited to the category from which they were charged off. "Interchange"
consists of fees received by Citibank (South Dakota), as a credit card-issuing
bank, from MasterCard International and VISA as partial compensation for taking
credit risk, absorbing fraud losses and funding receivables for a limited
period before initial billing. Interchange varies from approximately 1% to 2%
of the transaction amount, but these amounts may be changed by MasterCard
International or VISA.

    In general, the allocable share of monthly collections of finance charge
receivables and principal receivables available to the collateral certificate,
to other series of investor certificates issued by the master trust and to the
sellers' interest is determined as follows:

  .   first, collections of finance charge receivables and collections of
      principal receivables are allocated among the different series of
      certificates issued by the master trust, including the series to which
      the collateral certificate belongs, pro rata based on the Invested
      Amount of each series; and
--------
*VISA(R) and MasterCard(R) are registered trademarks of VISA U.S.A. Inc. and
    MasterCard International Incorporated, respectively.

                                       52
<PAGE>

  .   second, following the allocation to each series, collections of
      finance charge receivables and principal receivables are further
      allocated between the holders of each series of investor certificates
      under the master trust and the Banks pro rata based on the aggregate
      Invested Amount of the master trust investor certificates and the
      principal receivables allocable to the sellers' interest.

    In general, the Invested Amount of each other series of certificates issued
by the master trust will equal the stated dollar amount of participation
certificates issued to investors in that series less unreimbursed charge-offs
of principal receivables in the master trust allocated to those investors,
principal payments made to those investors and deposits made to any principal
funding account for the series. The sellers' interest, which is owned by
Citibank (South Dakota) and Citibank (Nevada), represents the interest in the
principal receivables in the master trust at the end of the relevant month not
represented by any series of investor certificates.

    Servicing fees and losses on principal receivables in the master trust
arising from failure of cardholders to pay, charge-offs or otherwise are
allocated among series and between investors in each series and the sellers'
interest generally in the same manner as finance charge collections.

    Each month, the master trust will allocate collections of finance charge
receivables and principal receivables as well as the servicing fee and losses
to the investor certificates outstanding under the master trust, including the
collateral certificate. The master trust deducts the collateral certificate's
share of the servicing fee from its share of the collections of finance charge
receivables, and deducts the collateral certificate's share of losses from its
share of collections of finance charge receivables and/or principal
receivables. The servicing fee is described under "The Master Trust--The
Servicer."

    Allocations of losses, servicing fees and collections of finance charge
receivables and principal receivables are made pro rata for each month based on
the invested amount of each investor certificate under the master trust,
including the collateral certificate, and the principal receivables allocable
to the sellers' interest. For example, if the total principal receivables in
the master trust at the end of the month is 500, the invested amount of the
collateral certificate is 100, the invested amounts of the other investor
certificates are 200 and the sellers' interest is 200, the collateral
certificate is entitled, in general, to 1/5--or 100/500--of the cash received
each month.

    There is an exception to the pro rata allocations described in the
preceding paragraph. In the master trust, when the principal amount of an
master trust investor certificate other than the collateral certificate begins
to amortize, a special allocation procedure is followed. In this case,
collections of principal receivables continue to be allocated between investors
in the series and the sellers' interest as if the invested amount of the series
had not been reduced by principal collections deposited to a principal funding
account or paid to investors. Allocations of principal collections between the
investors in a series and the sellers' interest is based on the invested amount
of the series "fixed" at the time immediately before the first deposit of
principal collections into a principal funding subaccount or the time
immediately

                                       53
<PAGE>

before the first payment of principal collections to investors. Distributions
of ongoing collections of finance charge receivables, as well as losses and
expenses, however, are not allocated on this type of a fixed basis. In the case
of the collateral certificate, each class of notes is treated as a separate
series of investor certificates that becomes "fixed" immediately before the
issuer begins to allocate principal collections to the principal funding
subaccount for that class, whether for budgeted deposits or prefunding, or upon
the occurrence of the expected principal payment date, an early redemption
event, event of default or other optional or mandatory redemption.

    If principal collections allocated to the collateral certificate are needed
to pay the notes or to make a deposit into the trust accounts within a month,
they will be deposited into the issuer's collection account. Otherwise,
collections of principal receivables allocated to the collateral certificate
will be reallocated to other series of master trust investor certificates which
have principal collection shortfalls--which does not reduce the Invested Amount
of the collateral certificate--or reinvested in the master trust to maintain
the Invested Amount of the collateral certificate. If the collateral
certificate has a principal collection shortfall, but other series of investor
certificates have excess principal collections, a portion of the other excess
principal collections allocated to other series of investor certificates will
be reallocated to the collateral certificate and deposited into the issuer's
collection account--which reduces the Invested Amount of the collateral
certificate.

    If a class of notes has directed the master trust to sell credit card
receivables following an event of default and acceleration, or on the
applicable legal maturity date, as described in "Deposit and Application of
Funds--Sale of Credit Card Receivables," the only source of funds to pay
principal of and interest on that class will be the proceeds of that sale and
investment earnings on the applicable principal funding subaccount.

Derivative Agreements

    Some notes may have the benefit of one or more derivative agreements,
including interest rate or currency swaps, caps, collars, guaranteed investment
contracts or other similar agreements with various counterparties. Citibank
(South Dakota), Citibank (Nevada) or any of their affiliates may be
counterparties to a derivative agreement. In general, the issuer will receive
payments from counterparties to the derivative agreements in exchange for the
issuer's payments to them, to the extent required under the derivative
agreements. The specific terms of each derivative agreement and a description
of each counterparty will be included in the applicable supplement to this
prospectus for those notes. We refer to the agreements described in this
paragraph as "derivative agreements."

The Trust Accounts

    The issuer has established a collection account for the purpose of
receiving payments of finance charge collections and principal collections from
the master trust payable under the collateral certificate.


                                       54
<PAGE>

    The issuer has also established a principal funding account and interest
funding account, which will have subaccounts for each class and subclass of
notes of a series, and a Class C reserve account, which will have subaccounts
for each class and subclass of Class C notes of a series. If specified in a
supplement to this prospectus, the issuer may establish supplemental accounts
for any series, class or subclass of notes.

    Each month, distributions on the collateral certificate will be deposited
into the collection account, and then reallocated to the principal funding
account, the interest funding account, the Class C reserve account, any
supplemental account, to payments under any applicable derivative agreements,
and to the other purposes as specified in "Deposit and Application of Funds" or
in a supplement to this prospectus. However, for so long as Citibank (South
Dakota) is the servicer of the master trust and manager of the issuer and
Citibank (South Dakota) maintains a certificate of deposit rating of at least
A-1 and P-1, or their equivalent, by the rating agencies, Citibank (South
Dakota) may commingle funds received from the collateral certificate until the
business day before the payment date of a class of notes, instead of
immediately depositing those funds into the trust accounts.

    Funds on deposit in the principal funding account and the interest funding
account will be used to make payments of principal of and interest on the
notes. Payments of principal of and interest on the notes will be made from
funds on deposit in the accounts when the payments are due, either in the month
when the funds are deposited into the accounts, or in later months--for
example, if principal must be accumulated for payment at a later date, or if
interest is payable quarterly, semiannually or at another interval less
frequently than monthly.

    If the issuer anticipates that the amount of principal collections that
will be deposited into the collection account in a particular month will not be
enough to pay all of the stated principal amount of a note that has an expected
principal payment date in that month, the issuer may begin to withdraw funds
from the collection account in months before the expected principal payment
date and deposit those funds into the principal funding subaccount established
for that class to be held until the expected principal payment date of that
note. If the earnings on funds in the principal funding subaccount are less
than the yield payable on the applicable class of notes--after giving effect to
net payments and receipts under any derivative agreements--additional funds
will be deposited in the interest funding subaccount as described under
"Deposit and Application of Funds--Deposit of Principal Funding Subaccount
Earnings in Interest Funding Subaccounts; Principal Funding Subaccount Earnings
Shortfall."

    If interest on a note is not scheduled to be paid every month--for example,
if interest on that note is payable quarterly, semiannually or at another
interval less frequently than monthly--the issuer will withdraw a portion of
funds from the collection account in months in which no interest payment is due
and deposit those funds into the interest funding subaccount for that note to
be held until the interest is due. See "Deposit and Application of Funds--
Targeted Deposits of Finance Charge Collections and Reallocated Principal
Collections to the Interest Funding Account."


                                       55
<PAGE>

    The Class C reserve account will initially not be funded. If the finance
charge collections generated by the master trust fall below a level specified
in the applicable supplement to this prospectus, the Class C reserve account
will be funded as described under "Deposit and Application of Funds--Targeted
Deposits to the Class C Reserve Account."

    Funds on deposit in the Class C reserve account will be available to
holders of Class C notes to cover shortfalls of interest payable on interest
payment dates. Funds on deposit in the Class C reserve account will also be
available to holders of Class C notes on any day when principal is payable, but
only to the extent that the nominal liquidation amount of the Class C notes
plus funds on deposit in the applicable Class C principal funding subaccount is
less than the outstanding dollar principal amount of the Class C notes.

    Only the holders of Class C notes will have the benefit of the Class C
reserve account. See "Deposit and Application of Funds--Withdrawals from the
Class C Reserve Account."

    The accounts described in this section are referred to as "trust accounts."
Trust accounts may only be maintained in a segregated trust account with the
corporate trust department of a United States bank or any domestic branch of a
foreign bank or at a United States bank, or any domestic branch of a foreign
bank, which has the highest long-term or short-term rating by the rating
agencies that rate the notes. Amounts maintained in trust accounts may only be
invested in investments the obligor on which has the highest rating by those
rating agencies. Investment earnings on funds in the principal funding
subaccount for a class of notes will be applied to make interest payments on
that class of notes. Investment earnings on funds in the other trust accounts
will be allocated as described under "Deposit and Application of Funds--
Allocation of Finance Charge Collections to Accounts." Any loss resulting from
the investment of funds in the trust accounts will be charged to the trust
subaccount incurring the loss.

Limited Recourse to the Issuer; Security for the Notes

    Only the portion of finance charge collections and principal collections
under the collateral certificate available to a class of notes after giving
effect to all allocations and reallocations, the applicable trust accounts, any
applicable derivative agreement and proceeds of sales of credit card
receivables held by the master trust provide the source of payment for
principal of or interest on any class of notes. Noteholders will have no
recourse to any other assets of the issuer or any other person or entity for
the payment of principal of or interest on the notes.

    The notes of all series are secured by a shared security interest in the
collateral certificate and the collection account, but each class of notes is
entitled to the benefits of only that portion of those assets allocated to it
under the indenture. Each class of notes is also secured by a security interest
in the applicable principal funding subaccount, the applicable interest funding
subaccount, in the case of classes of Class C notes, the applicable Class C
reserve subaccount, any applicable supplemental account, and by a security
interest in any applicable derivative agreement.


                                       56

The Indenture Trustee

    Bankers Trust Company is the trustee under the indenture for the notes. Its
principal corporate trust office is located at Four Albany Street, 10th Floor,
New York, New York 10006.

    The indenture trustee may resign at any time. The issuer may also remove
the indenture trustee if the indenture trustee is no longer eligible to act as
trustee under the indenture or if the indenture trustee becomes insolvent. In
all circumstances, the issuer must appoint a successor trustee for the notes.
Any resignation or removal of the indenture trustee and appointment of a
successor trustee will not become effective until the successor trustee accepts
the appointment.

    The issuer or its affiliates may maintain accounts and other banking or
trustee relationships with the indenture trustee and its affiliates.

                        DEPOSIT AND APPLICATION OF FUNDS

    The indenture specifies how finance charge collections and principal
collections allocated to the collateral certificate and payments received from
counterparties under derivative agreements will be deposited into the trust
accounts established for each class or subclass of notes to provide for the
payment of principal and interest on those notes as the payments become due.
Following are summaries of those provisions.

Allocation of Finance Charge Collections to Accounts

    Each month, the indenture trustee will allocate, or cause to be allocated,
finance charge collections--together with any other funds to be treated as
finance charge collections--received that month from the collateral certificate
and investment earnings on funds in the trust accounts other than the principal
funding account as follows:

  .   first, to pay the fees and expenses of the indenture trustee;

  .   second, to make the targeted deposit to the interest funding account
      to fund the payment of interest on the notes, other than any class of
      notes that has directed the master trust to sell credit card
      receivables as described in "--Sale of Credit Card Receivables";

  .   third, to make a reinvestment in the collateral certificate if the
      nominal liquidation amount of any class of notes, plus any amounts on
      deposit in that class's principal funding subaccount, is less than the
      outstanding dollar principal amount of that class, or to reimburse
      reallocations from the principal funding subaccount of any class of
      notes that has directed a sale of receivables;

  .   fourth, to make the targeted deposit to the Class C reserve account,
      if any; and

  .   fifth, to the issuer.

                                       57
<PAGE>

    Other funds to be treated as finance charge collections include income and
other gain on the trust accounts--other than the principal funding account--and
amounts remaining on deposit in the trust subaccounts after payment in full of
the applicable subclass of notes.

Allocation of Principal Collections to Accounts

    Each month, the indenture trustee will allocate, or cause to be allocated,
principal collections received that month from the collateral certificate--
together with other funds that are to be treated as principal collections--as
follows:

  .   first, if the amount available under item second under "--Allocation
      of Finance Charge Collections to Accounts" is not enough to make the
      full targeted deposit into the interest funding subaccount for any
      class of notes, principal collections allocable to the subordinated
      classes of notes of that series--together with proceeds of sales of
      principal receivables under "--Sale of Credit Card Receivables" in the
      principal funding subaccounts of the subordinated classes of notes of
      that series--will be reallocated to the senior classes of notes of
      that series. Those reallocations will be made in the following order:

     --  (1), from Class C notes of that series to Class A notes of that
         series;

     --  (2), from Class C notes of that series to Class B notes of that
         series; and

     --  (3), from Class B notes of that series to Class A notes of that
         series;

  .   second, to make the targeted deposits to the principal funding
      account; and

  .   third, to the master trust, to be reinvested in the collateral
      certificate.

    Other funds that are to be treated as principal collections include funds
released from principal funding subaccounts when prefunding is no longer
necessary, as described in "--Withdrawals from Principal Funding Account." If a
class of notes directs the master trust to sell credit card receivables as
described in "--Sale of Credit Card Receivables," the proceeds of that sale
will be treated as principal collections for item first, but not for item
second or third.

    The amount of principal collections that may be allocated to pay interest
is limited as described below under "Deposit and Application of Funds--Limit on
Reallocations of Principal Collections from Subordinated Classes to Senior
Classes of Single Issuance Series" and "--Limit on Reallocations of Principal
Collections from Subordinated Classes to Senior Classes of Multiple Issuance
Series."

    The Invested Amount of the collateral certificate will be reduced by the
amount of principal collections used to make deposits into the interest funding
account and deposits

                                       58
<PAGE>

into the principal funding account. If the Invested Amount of the collateral
certificate is reduced because principal collections have been used to make
deposits into the interest funding account, the amount of finance charge
collections and principal collections allocated to the collateral certificate
will be reduced in later months unless the reduction in the Invested Amount is
reimbursed from Excess Finance Charge Collections.

Targeted Deposits of Finance Charge Collections to the Interest Funding Account

    The aggregate deposit targeted to be made each month to the interest
funding account with finance charge collections and other amounts that are to
be treated as finance charge collections will be equal to the sum of the
interest funding account deposits targeted to be made for each class or
subclass of notes. These requirements are set forth below. The deposit targeted
for any month will also include any shortfall in the targeted deposit from any
prior month. A supplement to this prospectus for a class or subclass of notes
may specify additional or different monthly deposits.

  .   Interest Payments not Covered by a Derivative Agreement. If a class or
      subclass of notes provides for interest payments that are not covered
      by a derivative agreement, the deposit targeted for that class or
      subclass of notes for any month will be equal to the amount of
      interest accrued on the outstanding dollar principal amount of that
      class or subclass, during the period from the prior Monthly Interest
      Date--or the date of issuance of that class or subclass for the
      determination for the first Monthly Interest Date--to the first
      Monthly Interest Date after the end of the month. If a class or
      subclass of notes provides for interest payments that are partially
      covered by a derivative agreement--for example, an interest rate cap--
      the deposit targeted for that class or subclass for any month will be
      computed in the same manner, but will be reduced by the amount of the
      payment for interest received from the derivative counterparty.

  .   Notes with Performing Derivative Agreements. If a class or subclass of
      U.S. dollar notes or foreign currency notes has a Performing
      derivative agreement for interest that provides for monthly payments
      to the applicable derivative counterparty, the deposit targeted for
      that class or subclass of notes is equal to the amount required to be
      paid to the applicable derivative counterparty on the payment date
      following the end of that month.

     If a class or subclass of U.S. dollar notes or foreign currency notes
     has a Performing derivative agreement for interest that provides for
     payments less frequently than monthly to the applicable derivative
     counterparty, the deposit targeted for that class or subclass of notes
     for each month is equal to the amount required to be paid to the
     applicable derivative counterparty on the next payment date following
     the end of that month taking into account the applicable interest rate
     and day count convention, but allocated pro rata to that month as
     provided in the derivative agreement, or as otherwise provided in the
     applicable derivative agreement.

                                       59
<PAGE>

  .   U.S. Dollar Notes with Non-Performing Derivative Agreements. If a
      class or
     subclass of U.S. dollar notes has a non-Performing derivative
     agreement for interest, the deposit targeted for that class or
     subclass for each month unless otherwise provided in the applicable
     derivative agreement will be equal to the amount of interest accrued
     on the outstanding dollar principal amount of those notes, after
     deducting any amounts on deposit in the applicable principal funding
     subaccount, during the period from the prior Monthly Interest Date to
     the first Monthly Interest Date after the end of that month to the
     extent which that interest would have been covered by the non-
     Performing derivative agreement.

  .   Foreign Currency Notes with Non-Performing Derivative Agreements. If a
      class or subclass of foreign currency notes has a non-Performing
      derivative agreement for interest that provides for monthly payments
      to the applicable derivative counterparty, then the calculation of the
      targeted deposit is made with reference to the amount of U.S. dollars
      that would have been payable to the applicable derivative counterparty
      on the payment date following the applicable month if the derivative
      agreement were Performing, or as otherwise provided in the applicable
      derivative agreement.

      If a class or subclass of foreign currency notes has a non-Performing
      derivative agreement for interest that provides for payments less
      frequently than monthly to the applicable derivative counterparty, the
      deposit targeted for that class or subclass of notes for each month is
      equal to the amount that would have been required to be paid to the
      applicable derivative counterparty on the next payment date following
      the end of that month taking into account the applicable interest rate
      and day count convention, but allocated pro rata to that month as
      provided in the derivative agreement, or as otherwise provided in the
      applicable derivative agreement.

  .   Discount Notes.  In the case of a class or subclass of discount notes,
      the deposit targeted for that class or subclass of notes for any
      month, in addition to any applicable stated interest as determined
      under the four items above, is the amount of accretion of principal of
      that class or subclass of notes from the prior Monthly Principal
      Date--or in the case of the first Monthly Principal Date, from the
      date of issuance of that class or subclass--to the first Monthly
      Principal Date after the end of the month.

Each of the deposits described above will be reduced proportionately for any
funds on deposit in the principal funding subaccount for the applicable class
or subclass of notes, for which the applicable deposit will be made to the
interest funding account as described under "Deposits of Principal Funding
Subaccount Earnings in Interest Funding Subaccount--Principal Funding
Subaccount Earnings Shortfall."

    In addition, for each month each of the following deposits will be targeted
to be made to the interest funding account with finance charge collections and
other amounts to be treated as finance charge collections, pro rata with the
deposits described above.

  .   Specified Deposits. If the applicable supplement to this prospectus
      for any class or subclass of notes specifies deposits in addition to
      or different from the deposits

                                       60
<PAGE>

      described above to be made to the interest funding subaccount for that
      class or subclass, the deposits targeted for that class or subclass
      each month are the specified amounts.

  .   Interest on Overdue Interest. Unless otherwise specified in a
      supplement to this prospectus, the deposit targeted for any class or
      subclass of notes that has accrued and overdue interest for any month
      will be the interest accrued on that overdue interest. Interest on
      overdue interest will be computed from and including the interest
      payment date in that month to but excluding the interest payment date
      next following that month, at the rate of interest applicable to
      principal of that class or subclass.

    If the amount of finance charge collections is not enough to make all of
the deposits described above for any class of notes, then principal
collections allocable to subordinated classes of notes and receivables sales
proceeds received by subordinated classes of notes as described under "--Sales
of Credit Card Receivables" will be reallocated first, from the Class C notes
of that series to the Class A notes of that series, second, from the Class C
notes of that series to the Class B notes of that series, and third, from the
Class B notes of that series to the Class A notes of that series.

    Each deposit to the interest funding account will be made on the
applicable Monthly Interest Date, or as much earlier as necessary to make
timely deposit or payment to the applicable interest funding subaccount or
derivative counterparty.

    A single class or subclass of notes may be entitled to more than one of
the preceding deposits, plus deposits from other sources, described under "--
Deposit of Principal Funding Subaccount Earnings in Interest Funding
Subaccounts; Principal Funding Subaccount Earnings Shortfall."

    A class of notes that has directed the master trust to sell credit card
receivables as described in "--Sale of Credit Card Receivables," will not be
entitled to receive any of the preceding deposits to be made to its interest
funding subaccount from finance charge collections, other amounts to be
treated as finance charge collections or reallocated principal collections.

Payments Received from Derivative Counterparties for Interest

    Payments received under derivative agreements for interest on notes
payable in U.S. dollars will be deposited into the applicable interest funding
subaccount. Payments received under derivative agreements for interest on
foreign currency notes will be made directly to the applicable paying agent
for payment to the holders of those notes, or as otherwise specified in the
applicable supplement to this prospectus.


                                      61

Deposit of Principal Funding Subaccount Earnings in Interest Funding
Subaccounts; Principal Funding Subaccount Earnings Shortfall

    Investment earnings on amounts on deposit in the principal funding
subaccount for a class of notes will be deposited monthly into that class's
interest funding subaccount.

    The issuer will notify the master trust from time to time of the aggregate
amount on deposit in the principal funding account, other than with respect to
classes that have directed the master trust to sell credit card receivables as
described in "--Sale of Credit Card Receivables." Whenever there is any amount
on deposit in any principal funding subaccount, other than with respect to
classes that have directed the master trust to sell receivables, the master
trust will designate an equal amount of the sellers' interest, and the finance
charge collections allocable to the designated portion of the sellers' interest
will be applied as follows: On each Monthly Interest Date, the issuer will
calculate the targeted amount of principal funding subaccount earnings for each
class or subclass of notes, which will be equal to the amount that the funds on
deposit in each principal funding subaccount would earn at the interest rate
payable by the issuer--taking into account payments and receipts under
applicable derivative agreements--on the related class or subclass of notes. As
a general rule, if the amount actually earned on the funds on deposit is less
than the targeted amount of earnings, then the shortfall will be made up from
the finance charge collections allocated to the corresponding designated
portion of the sellers' interest. A class of notes that has directed the master
trust to sell credit card receivables as described in "--Sale of Credit Card
Receivables," will not be entitled to any finance charge collections from the
designated portion of the sellers' interest if there is an earnings shortfall
in its principal funding subaccount.

    If the amount of principal funding subaccount earnings for any class or
subclass of notes for any month is greater than the targeted principal funding
subaccount earnings for that month, the amount of the excess will be treated as
finance charge collections.

Deposits of Withdrawals from the Class C Reserve Account to the Interest
Funding Account

    Withdrawals made from any Class C reserve subaccount will be deposited into
the applicable interest funding subaccount to the extent described under "--
Withdrawals from the Class C Reserve Account."

Allocation to Interest Funding Subaccounts

    The aggregate deposit of finance change collections and reallocated
principal collections made each month to the interest funding account will be
allocated, and a portion deposited in the interest funding subaccount
established for each class or subclass of notes, based on the following rules:

  (1) Available Amounts Are Equal to Targeted Amounts. If the aggregate
      amount of finance charge collections available for deposit to the
      interest funding account is equal to the sum of the deposits of
      finance charge collections targeted by each class or subclass of
      notes, then that targeted amount is deposited in the interest funding
      subaccount established for each class or subclass.

                                       62
<PAGE>

  (2) Available Amounts Are Less Than Targeted Amounts. If the aggregate
      amount of finance charge collections available for deposit to the
      interest funding account is less than the sum of the deposits of
      finance charge collections targeted by each class or subclass of
      notes, then the amount available to be deposited into the interest
      funding account will be allocated to each series of notes pro rata
      based on the aggregate nominal liquidation amount of notes in that
      series.

     .   For all series of notes identified as "Group 1" series, the
         allocation of finance charge collections is reaggregated into a
         single pool, and reallocated to each series, class or subclass of
         notes in Group 1 pro rata based on the amount of the deposit
         targeted by that series, class or subclass and not based on the
         nominal liquidation amount of notes in that series, class or
         subclass.

     .   For all series of notes identified as in another group, the
         allocation of finance charge collections will be based on a rule
         for that group set forth in a supplement to this prospectus.

  (3) Other Funds not Reallocated. Funds on deposit in an interest funding
      subaccount from earlier months, funds representing interest on amounts
      in deposit in the related principal funding subaccount, and payments
      received from derivative counterparties in the current month will not
      be reallocated to other interest funding subaccounts. These funds
      remain in the interest funding subaccount into which they were
      deposited until they are withdrawn to be paid to the applicable
      noteholder or derivative counterparty.

    The principal collections deposited into the interest funding account will
be allocated to each class or subclass of Class A notes and Class B notes based
on the amount of the deposit targeted by that class or subclass. However, these
deposits are limited to the extent described under "Deposit and Application of
Funds--Limit on Reallocations of Principal Collections from Subordinated
Classes to Senior Classes of Single Issuance Series" and "--Limit on
Reallocations of Principal Collections from Subordinated Classes to Senior
Classes of Multiple Issuance Series."

Withdrawals from Interest Funding Account

    After giving effect to all deposits and reallocations of funds in the
interest funding account in a month, the following withdrawals from the
applicable interest funding subaccount will be made, but in no event more than
the amount on deposit in the applicable interest funding subaccount. A class or
subclass of notes may be entitled to more than one of the following withdrawals
in a particular month:

  (1) Withdrawals for U.S. Dollar Notes with no Derivative Agreement for
      Interest. On each applicable interest payment date for each class or
      subclass of U.S. dollar notes, an amount equal to interest due on the
      applicable class or subclass of notes on the applicable interest
      payment date will be withdrawn from that interest

                                       63
<PAGE>

      funding subaccount and paid to the applicable paying agent, or as
      otherwise provided in the applicable supplement to this prospectus.

  (2) Withdrawals for Discount Notes. On each applicable Monthly Principal
      Date, with respect to each class or subclass of discount notes, an
      amount equal to the amount of the accretion of principal of that class
      or subclass of notes from the prior Monthly Principal Date, or in the
      case of the first Monthly Principal Date, the date of issuance of that
      class or subclass, to the applicable Monthly Principal Date will be
      withdrawn from that interest funding subaccount and invested in the
      collateral certificate, or as otherwise provided in the applicable
      supplement to this prospectus.

  (3) Withdrawals for Notes with Performing Derivative Agreements for
      Interest. On each date on which a payment is required under the
      applicable derivative agreement, or a date specified in the applicable
      supplement to this prospectus, with respect to any class or subclass
      of notes that has a Performing derivative agreement for interest, an
      amount equal to the amount of the payment to be made under the
      applicable derivative agreement will be withdrawn from that interest
      funding subaccount and paid to the applicable derivative counterparty,
      or as otherwise provided in the applicable supplement to this
      prospectus.

  (4) Withdrawals for Notes with Non-Performing Derivative Agreements for
      Interest in U.S. Dollars. On each interest payment date, or a date
      specified in the applicable supplement to this prospectus, for a class
      or subclass of U.S. dollar notes that has a non-Performing derivative
      agreement for interest, an amount equal to the amount of interest
      payable on that interest payment date will be withdrawn from that
      interest funding subaccount and paid to the applicable paying agent,
      or as otherwise provided in the applicable supplement to this
      prospectus.

  (5) Withdrawals for Notes with Non-Performing Derivative Agreements for
      Foreign Currency Interest. On each interest payment date with respect
      to a class or subclass of foreign currency notes that has a non-
      Performing derivative agreement for interest, or a date specified in
      the applicable supplement to this prospectus, an amount equal to the
      amount of U.S. dollars necessary to be converted at the applicable
      exchange rate to pay the foreign currency interest due on that class
      or subclass of notes on the interest payment date will be withdrawn
      from that interest funding subaccount and converted to the applicable
      foreign currency at the applicable exchange rate and paid to the
      applicable paying agent. Any excess U.S. dollar amount will be
      retained on deposit in the applicable interest funding subaccount to
      be applied to make interest payments on later interest payment dates,
      or as otherwise provided in the applicable supplement to this
      prospectus.

    If the aggregate amount available for withdrawal from an interest funding
subaccount is less than all withdrawals required to be made from that
subaccount in a month after giving effect to all deposits and reallocations,
then the amounts on deposit in the interest funding account will be withdrawn
and, if payable to more than one person, applied pro rata based on the amounts
of the withdrawals required to be made.

                                       64
<PAGE>

    After payment in full of any class or subclass of notes, any amount
remaining on deposit in the applicable interest funding subaccount will be
treated as finance charge collections.

Targeted Deposits of Principal Collections to the Principal Funding Account

    The aggregate amount targeted to be deposited into the principal funding
account in any month will be the sum of the following amounts. If a single
class or subclass of notes is entitled to more than one of the following
deposits in any month, the deposit targeted for that month will be the highest
of the targeted amounts for that month, plus any shortfall in the targeted
deposit from any prior month, but not more than the nominal liquidation amount
of that class of Notes. These requirements are set forth below. A supplement to
this prospectus for a class or subclass of notes may specify additional or
different monthly deposits.

  (1) Expected Principal Payment Date. With respect to the last month before
      the expected principal payment date of a class or subclass of notes,
      and each following month, the deposit targeted for that class or
      subclass of notes with respect to that month is equal to the aggregate
      nominal liquidation amount of that class or subclass of notes.

  (2) Budgeted Deposits. Each month beginning with the twelfth month before
      the expected principal payment date of a class or subclass of Class A
      notes, the deposit targeted to be made into the principal funding
      subaccount for that class or subclass will be the monthly accumulation
      amount for that class or subclass specified in the applicable
      supplement to this prospectus or, if no amount is specified, equal to,
      in the case of a single issuance series, one-eleventh, and in the case
      of a multiple issuance series, one-twelfth, of the projected
      outstanding dollar principal amount of that class or subclass of notes
      as of its expected principal payment date, after deducting any amounts
      already on deposit in the applicable principal funding subaccount.

     The issuer may postpone the date of the targeted deposits under the
     previous sentence. If the issuer and the master trust determine that
     less than eleven months or twelve months, as applicable, would be
     required to accumulate the principal collections necessary to pay a
     class of notes on its expected principal payment date, using
     conservative historical information about payment rates of principal
     receivables under the master trust, and after taking into account all
     of the other expected payments of principal of master trust investor
     certificates and notes to be made in the next eleven months or twelve
     months, as applicable, then the start of the accumulation period may
     be postponed each month by one month, with proportionately larger
     accumulation amounts for each month of postponement.

  (3) Prefunding of the Principal Funding Account for Senior Classes. If the
      issuer determines that any expected principal payment date, early
      redemption event, event of default or other date on which principal is
      payable because of a mandatory or optional redemption with respect to
      any class or subclass of Class C notes will occur at a time when the
      payment of all or part of that class or subclass of Class C notes
      would be prohibited because it would cause a deficiency in the
      required

                                       65
<PAGE>

      subordinated amount of the Class A notes or Class B notes of the same
      series, the targeted deposit amount for the Class A notes and Class B
      notes of that series will be an amount equal to the portion of the
      nominal liquidation amount of the Class A notes and Class B notes that
      would have to cease to be outstanding in order to permit the payment
      of that class of Class C notes.

      If the issuer determines that any expected principal payment date,
      early redemption event, event of default or other date on which
      principal is payable because of a mandatory or optional redemption
      with respect to any Class B notes will occur at a time when the
      payment of all or part of that class or subclass of Class B notes
      would be prohibited because it would cause a deficiency in the
      required subordinated amount of the Class A notes of that series, the
      targeted deposit amount for the Class A notes of that series will be
      an amount equal to the portion of the nominal liquidation amount of
      the Class A notes that would have to cease to be outstanding in order
      to permit the payment of that class of Class B notes.

      Prefunding of the principal funding subaccount for the senior classes
      of a series will continue until

     .   enough notes of senior classes of that series are repaid so that
         the subordinated notes that are payable are no longer necessary to
         provide the required subordinated amount of the outstanding senior
         notes; or

     .   in the case of multiple issuance series, new classes of
         subordinated notes of that series are issued so that the
         subordinated notes that are payable are no longer necessary to
         provide the required subordinated amount of the outstanding senior
         notes; or

     .   the principal funding subaccounts for the senior classes of notes
         of that series are prefunded so that none of the subordinated
         notes that are paid are necessary to provide the required
         subordinated amount.

      When the prefunded amounts are no longer necessary, they will be
      withdrawn from the principal funding account and treated as principal
      collections for allocation to other classes of notes as described in
      "Deposit and Application of Funds--Allocation of Principal Collections
      to Accounts," or reinvested in the collateral certificate.

      If any class of senior notes becomes payable as a result of an early
      redemption event, event of default or other optional or mandatory
      redemption, or upon reaching its expected principal payment date, any
      prefunded amounts on deposit in its principal funding subaccount will
      be paid to senior noteholders of that class and deposits to pay the
      notes will continue as necessary to pay that class.

  (4) Event of Default, Early Redemption Event or Other Optional or
      Mandatory Redemption. If any class or subclass of notes has been
      accelerated after the occurrence of an event of default during that
      month, or if any class or subclass of notes is required to be redeemed
      following an early redemption event or other

                                      66
<PAGE>

      optional or mandatory redemption, the deposit targeted for that class
      or subclass of notes with respect to that month is equal to the
      nominal liquidation amount of that class or subclass of notes.

Payments Received from Derivative Counterparties for Principal

    It is unlikely that any class or subclass of U.S. dollar notes will have a
derivative agreement for principal. Payments received under derivative
agreements for principal of foreign currency notes will be made directly to
the applicable paying agent for payment to the holders of the applicable class
or subclass of notes, or as otherwise specified in the applicable supplement
to this prospectus.

Deposits of Withdrawals from the Class C Reserve Account to the Principal
Funding Account

    Withdrawals from any Class C reserve subaccount will be deposited into the
applicable principal funding subaccount to the extent described under "--
Withdrawals from the Class C Reserve Account."

Deposits of Proceeds of the Sale of Credit Card Receivables

    The net proceeds of the sale of any credit card receivables by the master
trust that are received by the issuer will be deposited into the applicable
principal funding subaccount. See "--Sale of Credit Card Receivables."

Reallocation of Funds on Deposit in the Principal Funding Subaccounts

    Funds on deposit in the principal funding account each month will be
allocated, and a portion deposited in the principal funding subaccount
established for each class or subclass of notes, based on the following rules:

  (1) Deposits Equal Targeted Amounts. If the aggregate deposit to the
      principal funding account is equal to the sum of the deposits targeted
      by each class or subclass of notes, then the targeted amount is
      deposited in the principal funding subaccount established for each
      class or subclass.

  (2) Deposits Are Less Than Targeted Amounts. If the amount on deposit in
      any principal funding subaccount for a class of Class A notes of a
      series is less than the sum of the deposits targeted with respect to
      that class, other than the amount targeted for deposit with respect to
      an optional redemption of that class to the extent specified in the
      applicable supplement to this prospectus, then amounts on deposit or
      to be deposited in the principal funding subaccounts established for
      Class B notes and Class C notes for that series will be reallocated to
      make the targeted deposit into the Class A principal funding
      subaccount, to be made first from the Class C principal funding
      subaccount in that series and second from Class B principal funding
      subaccount in that series. If more than one subclass of Class A note
      of a series needs to use amounts on deposit in the principal funding

                                      67
<PAGE>

      subaccount for the Class B notes and the Class C notes of that series,
      then withdrawals will be allocated pro rata based on the nominal
      liquidation amounts of the classes or subclasses of Class A notes that
      require funding.

      If the amount on deposit in any principal funding subaccount for a
      class of Class B notes of a series is less than the sum of the
      deposits targeted with respect to that class, other than the amount
      targeted for deposit with respect to an optional redemption of that
      class to the extent specified in the applicable supplement to this
      prospectus, then amounts on deposit or to be deposited in the
      principal funding subaccount established for Class C notes of that
      series will be reallocated to make the targeted deposit into the Class
      B principal funding subaccount. If more than one subclass of Class B
      notes of a series needs to use amounts on deposit in the principal
      funding subaccount for the Class C notes of that series, then
      withdrawals will be allocated pro rata based on the nominal
      liquidation amounts of the classes or subclasses of Class B notes that
      require funding.

  (3) Proceeds of Sales of Credit Card Receivables. Proceeds of sales of
      credit card receivables on deposit in the principal funding subaccount
      for a class of notes may not be reallocated to the principal funding
      subaccount for any senior class but may be reallocated to be treated
      as finance charge collections to pay interest on senior classes of
      notes of the same series or to reimburse charge-offs of principal
      receivables in the master trust. See "--Sales of Credit Card
      Receivables."

  (4) Other Funds not Reallocated. Funds on deposit in a principal funding
      subaccount from withdrawals from the Class C reserve account or
      payments received from derivative counterparties will not be
      reallocated to other principal funding subaccounts.

    Because the nominal liquidation amount of a class of notes is reduced by
amounts on deposit in that class's principal funding subaccount, the deposit of
principal collections into the principal funding subaccount for a subordinated
class of notes initially reduces the nominal liquidation amount of that
subordinated class. However, if funds are reallocated from the principal
funding subaccount for a subordinated class to the principal funding subaccount
for a senior class of the same series, the result is that the nominal
liquidation amount of the senior class, and not of the subordinated class, is
reduced by the amount of the reallocation.

    If the nominal liquidation amount of a subordinated class of notes has been
reduced by charge-offs of principal receivables in the master trust and
reallocations of principal collections to pay interest on senior classes of
notes, and then reimbursed from Excess Finance Charge Collections, the
reimbursed portion is no longer subordinated to notes of the senior classes of
the same series that were outstanding on the date of that reimbursement. This
reimbursed amount will not be reallocated to any notes that were outstanding
before the date of that reimbursement. However, in a multiple issuance series,
the reimbursed amount is subordinated to any notes of the senior classes of the
same series that were issued after the date of that reimbursement, and may be
reallocated to those notes.

Withdrawals from Principal Funding Account

    After giving effect to all deposits and reallocations of funds in the
principal funding account in a month, the following withdrawals from the
applicable principal funding subaccount will be made, but in no event more than
the amount on deposit in the applicable principal funding subaccount. A class
or subclass of notes may be entitled to more than one of the following
withdrawals in a particular month:

  (1) Withdrawals for U.S. Dollar Notes with no Derivative Agreement for
      Principal. On each applicable principal payment date, or a date
      specified in the applicable supplement to this prospectus, with
      respect to each class or subclass of U.S. dollar notes that has no
      derivative agreement for principal, an amount equal to the principal
      due on the applicable class or subclass of notes on the applicable
      principal payment date will be withdrawn from the applicable principal
      funding subaccount and paid to the applicable paying agent, or as
      otherwise provided in the applicable supplement to this prospectus.

  (2) Withdrawals for Notes with Performing Derivative Agreement for
      Principal. On each date on which a payment is required under the
      applicable derivative agreement, or a date specified in the applicable
      supplement to this prospectus, with respect to any class or subclass
      of notes that has a Performing derivative agreement for principal, an
      amount equal to the amount of the payment to be made under the
      applicable derivative agreement will be withdrawn from the applicable
      principal funding subaccount and paid to the applicable derivative
      counterparty, or as otherwise provided in the applicable supplement to
      this prospectus.

  (3) Withdrawals for Foreign Currency Notes with Non-Performing Derivative
      Agreements for Principal. On each principal payment date with respect
      to a class or subclass of foreign currency notes that has a non-
      Performing derivative agreement for principal, or a date specified in
      the applicable supplement to this prospectus, an amount equal to the
      amount of U.S. dollars necessary to be converted at the applicable
      exchange rate to pay the foreign currency principal due on that class
      or subclass of notes on the applicable principal payment date will be
      withdrawn from the applicable principal funding subaccount and
      converted to the applicable foreign currency at the prevailing spot
      exchange rate and paid to the applicable paying agent, or as otherwise
      provided in the applicable supplement to this prospectus. Any excess
      U.S. dollar amount will be retained on deposit in the applicable
      principal funding subaccount to be applied to make principal payments
      on later principal payment dates.

  (4) Withdrawal of Prefunded Amount. If prefunding of the principal funding
      subaccounts for senior classes of notes is no longer necessary as a
      result of payment of senior notes or issuance of additional
      subordinated notes, as described under "--Targeted Deposits of
      Principal Allocations to the Principal Funding Account--Prefunding of
      the Principal Funding Account for Senior Classes," the prefunded
      amounts will be withdrawn from the principal funding account and

                                       69
<PAGE>

      treated as principal collections for allocation to other classes of
      notes as described in "Deposit and Application of Funds--Allocation of
      Principal Collections to Accounts," or reinvested in the collateral
      certificate.

  (5) Withdrawal of Proceeds of Sales of Credit Card Receivables. If a
      subordinated class of notes has directed the master trust to sell
      credit card receivables as described in "--Sale of Credit Card
      Receivables," the proceeds of that sale will be withdrawn from the
      principal funding subaccount to the extent those proceeds are required
      to be treated as finance charge collections to make targeted deposits
      in the interest funding account as described in "--Allocation of
      Finance Charge Collections to Accounts" for the benefit of senior
      classes of the same series, and to the extent required to reimburse
      the master trust for credit card charge-offs allocated to the senior
      classes of the same series.

    After payment in full of any class or subclass of notes, any amount
remaining on deposit in the applicable principal funding subaccount will be
treated as finance charge collections.

Limit on Reallocations of Principal Collections from Subordinated Classes
Taken to Benefit Senior Classes of Single Issuance Series

    For single issuance series, the amount of principal collections that may
be reallocated from subordinated classes of notes to senior classes of the
same series is limited as follows:

    With respect to any Class A notes of a single issuance series, the
aggregate amount of

  .   all principal collections reallocated from Class C notes of that
      series to the interest funding subaccounts for Class A notes or Class
      B notes of that series; and

  .   all reductions in the nominal liquidation amount of the Class C notes
      of that series from allocations of charge-offs of principal
      receivables in the master trust

may not exceed the initial dollar principal amount of Class C notes for that
series, plus, in the case of discount notes, accretions of principal thereon.
Likewise the aggregate amount of

  .   all principal collections reallocated from Class B notes of that
      series to the interest funding subaccounts for Class A notes of that
      series; and

  .   all reductions in the nominal liquidation amount of the Class B notes
      of that series from allocations of charge-offs of principal
      receivables in the master trust

may not exceed the initial dollar principal amount of Class B notes for that
series, plus, in the case of discount notes, accretions of principal thereon.

    With respect to any Class B notes of a single issuance series, the
aggregate amount of

  .   all principal collections reallocated from Class C notes of that
      series to the interest funding subaccounts for Class A notes or Class
      B notes of that series; and

                                      70
<PAGE>

  .   all reductions in the nominal liquidation amount of the Class C notes
      of that series from allocations of charge-offs of principal
      receivables in the master trust

may not exceed the initial dollar principal amount of Class C notes for that
series, plus, in the case of discount notes, accretions of principal thereon.

  Proceeds of the sale of credit card receivables as described under "--Sale of
Credit Card Receivables" that are reallocated from a subordinated class of
notes to a senior class of notes are treated the same as reallocated principal
collections for purposes of computing the limits on reallocations.

Limit on Reallocations of Principal Collections from Subordinated Classes Taken
to Benefit Senior Classes of Multiple Issuance Series

    For multiple issuance series, the amount of principal collections that may
be reallocated from subordinated classes of notes to senior classes of the same
series is limited as follows:

    Limit on Reallocations to a Subclass of Class A Notes from Class C
Notes. Principal collections that would otherwise have been allocated to the
Class C notes of a series may be reallocated to the interest funding subaccount
for a subclass of Class A notes of the same series only to the extent, after
giving effect to that reallocation, that the Class A usage of the Class C
subordinated amount is not greater than the required subordinated amount of
Class C notes for that subclass of Class A notes. For this purpose, Class A
usage of Class C subordinated amount is equal to the sum of the following
amounts:

  .   the cumulative sum of principal collections previously reallocated
      from Class C notes of that series to the interest funding subaccount
      for that subclass of Class A notes.

  .   plus, a portion of each reallocation of principal collections from
      Class C notes of that series to the interest funding subaccounts for
      Class B notes of that series while that subclass of Class A notes is
      outstanding. These amounts will be treated as usage of the Class A
      required subordinated amount of Class C notes pro rata based on the
      ratio of the Class A required subordinated amount of Class B notes to
      the aggregate outstanding dollar principal amount of all Class B notes
      of that series.

  .   plus, the portion of the cumulative amount of charge-offs of principal
      receivables in the master trust that is treated as usage of the Class
      A required subordinated amount of Class C notes. This amount is equal
      to the sum of the following amounts, and is calculated on each day on
      which there is an allocation of charge-offs of principal receivables
      in held in the master trust:

     --  the amount of charge-offs of principal receivables in the master
         trust that are initially allocated to that subclass of Class A
         notes but then reallocated to Class C notes of that series.

                                       71
<PAGE>

     --  plus, a portion of the charge-offs of principal receivables in the
         master trust that are initially allocated to Class B notes of that
         series but then reallocated to Class C notes of that series. These
         amounts will be treated as usage of the Class A required
         subordinated amount of Class C notes pro rata based on the ratio
         of the Class A required subordinated amounts of Class B notes to
         the aggregate outstanding dollar principal amount of the Class B
         notes of that series.

     --  plus, a portion of the charge-offs of principal receivables in the
         master trust that are initially allocated to Class C notes of that
         series. These amounts will be treated as usage of the Class A
         required subordinated amount of Class C notes pro rata based on
         the ratio of the Class A required subordinated amounts of Class C
         notes to the aggregate outstanding dollar principal amount of the
         Class C notes of that series.

    Limit on Reallocations to a Subclass of Class A Notes from Class B
Notes. Principal collections that would otherwise have been allocated to the
Class B notes of a series may be reallocated to the interest funding subaccount
for a subclass of Class A notes of the same series only to the extent, after
giving effect to that reallocation, that the Class A usage of the Class B
subordinated amount is not greater than the required subordinated amount of
Class B notes for that subclass of Class A notes. For this purpose, Class A
usage of Class B subordinated amount is equal to the sum of the following
amounts:

  .   the cumulative sum of principal collections reallocated from Class B
      notes of that series to the interest funding subaccount for that
      subclass of Class A notes.

  .   plus, the portion of the charge-offs of principal receivables in the
      master trust that is treated as usage of the Class A required
      subordinated amount of Class B notes. This amount is equal to the sum
      of the following amounts, and is calculated on each day on which there
      is an allocation of charge-offs of principal receivables in held in
      the master trust:

     --  the amount of charge-offs of principal receivables in the master
         trust that are initially allocated to that subclass of Class A
         notes but then reallocated to Class B notes of that series.

     --  plus, a portion of the charge-offs of principal receivables in the
         master trust that are initially allocated to Class B notes of that
         series and not reallocated to Class C notes of that series. These
         amounts will be treated as usage of the Class A required
         subordinated amount of Class B notes pro rata based on the ratio
         of the Class A required subordinated amounts of Class B notes to
         the aggregate outstanding dollar principal amount of the Class B
         notes of that series.

    Limit on Reallocations to a Subclass of Class B Notes from Class C
Notes. Principal collections that would otherwise have been allocated to the
Class C notes of a series may be reallocated to the interest funding subaccount
for a subclass of Class B notes of the same series only to the extent, after
giving effect to that reallocation, that the Class B usage of the

                                       72
<PAGE>

Class C subordinated amount is not greater than the required subordinated
amount of Class C notes for that subclass of Class B notes. For this purpose,
Class B usage of Class C subordinated amount is equal to the sum of the
following amounts:

  .   the cumulative sum of principal collections reallocated from Class C
      notes of that series to the interest funding subaccount for that
      subclass of Class B notes.

  .   plus, a portion of each reallocation of principal collections from
      Class C notes of that series to the interest funding subaccounts for
      Class A notes of that series while that subclass of Class B notes is
      outstanding. These amounts will be treated as usage of the Class B
      required subordinated amount of Class C notes pro rata based on the
      ratio of the outstanding dollar principal amount of that subclass of
      Class B notes to the aggregate outstanding dollar principal amount of
      all Class B notes of that series.

  .   plus, the portion of the charge-offs of principal receivables in the
      master trust that is treated as usage of the Class B required
      subordinated amount of Class C notes. This amount is equal to the sum
      of the following amounts, and is calculated on each day on which there
      is an allocation of charge-offs of principal receivables in the master
      trust:

     --  the amount of charge-offs of principal receivables in the master
         trust that are initially allocated to that subclass of Class B
         notes but then reallocated to Class C notes of that series.

     --  plus, a portion of the charge-offs of principal receivables in the
         master trust that are initially allocated to Class A notes of that
         series but then reallocated to Class C notes of that series. These
         amounts will be treated as usage of the Class B required
         subordinated amount of Class C notes pro rata based on the ratio
         of outstanding dollar principal amount of that subclass of Class B
         notes to the aggregate outstanding dollar principal amount of the
         Class B notes of that series.

     --  plus, a portion of the charge-offs of principal receivables in the
         master trust that are initially allocated to Class C notes of that
         series. These amounts will be treated as usage of the Class B
         required subordinated amount of Class C notes pro rata based on
         the ratio of the Class B required subordinated amounts of Class C
         notes to the aggregate outstanding dollar principal amount of the
         Class C notes of that series.

    Proceeds of the sale of credit card receivables as described under "--Sale
of Credit Card Receivables" that are reallocated from a subordinated class of
notes to a senior class of notes are treated the same as reallocated principal
collections for purposes of computing the limits on reallocations.

Limit on Repayments of Subordinated Classes of Single Issuance Series

    In general, in the case of a single issuance series, no funds on deposit in
a principal funding subaccount will be applied to pay principal of any Class B
note of that series or to make a payment under a derivative agreement with
respect to principal for any Class B note

                                       73
<PAGE>

of that series, and no Class B note of that series held by the issuer, the
Banks or their affiliates will be canceled, unless, immediately before giving
effect to that payment or cancellation, no Class A notes of that series are
outstanding. However, funds on deposit in a principal funding subaccount may be
applied to pay principal of any Class B note of a single issuance series:

  .   to the extent that amounts on deposit in the principal funding
      subaccount for the Class B notes are attributable to reimbursements of
      earlier reductions in the nominal liquidation amount of the Class B
      notes; or

  .   if the Class A principal funding account has been prefunded as
      described in "Deposit and Application of Funds--Targeted Deposits of
      Principal Collections to the Principal Funding Account--Prefunding of
      the Principal Funding Account for Senior Classes."

    In general, in the case of a single issuance series, no funds on deposit in
a principal funding subaccount will be applied to pay principal of any Class C
note of that series or to make a payment under a derivative agreement with
respect to principal for any Class C note of that series, and no Class C note
of that series held by the issuer, the Banks or their affiliates will be
canceled, unless, immediately before giving effect to that payment or
cancellation, no Class A or Class B notes of that series are outstanding.
However, funds on deposit in a principal funding subaccount may be applied to
pay principal of any Class C note of a single issuance series:

  .   to the extent that amounts on deposit in the principal funding
      subaccount for the Class C notes are attributable to reimbursements of
      earlier reductions in the nominal liquidation amount of the Class C
      notes;

  .   if the Class A and Class B principal funding subaccounts have been
      prefunded as described in "Deposit and Application of Funds--Targeted
      Deposits of Principal Collections to the Principal Funding Account--
      Prefunding of the Principal Funding Account for Senior Classes," or

  .   with funds available from the applicable Class C reserve subaccount.

Limit on Repayments of Subordinated Classes of Multiple Issuance Series

    In the case of a multiple issuance series, in general, no funds on deposit
in a principal funding subaccount will be applied to pay principal of any note
of a subordinated class of that series or to make a payment under a derivative
agreement with respect to principal for any note of a subordinated class of
that series, and no note of a subordinated class of that series held by the
issuer, the Banks or their affiliates will be canceled, unless, following that
payment or cancellation, the remaining available subordinated amount of notes
of that subordinated class of that series is at least equal to the required
subordinated amount for the outstanding notes of the senior classes of that
series.

                                       74
<PAGE>

    For determining whether Class B notes may be repaid or canceled while Class
A notes of the same series are outstanding, the remaining available
subordinated amount of Class B notes is equal to the sum of:

  .   the aggregate nominal liquidation amount of all Class B notes of that
      series that will remain outstanding after giving effect to the
      repayment or cancellation of the Class B notes to be repaid or
      canceled in that month;

  .   plus, the aggregate amount on deposit in the principal funding
      subaccounts for all Class B notes of that series after giving effect
      to the repayment or cancellation of all Class B notes that are to be
      repaid or cancelled in that month (other than receivables sales
      proceeds on deposit in those subaccounts);

  .   plus, the amount of Class A usage of Class B required subordinated
      amount in that series, as described in "Deposit and Application of
      Funds--Limit on Reallocations of Principal Collections from
      Subordinated Classes Taken to Benefit Senior Classes of Multiple
      Issuance Series."

    For determining whether Class C notes may be repaid or canceled while Class
A notes of the same series are outstanding, the remaining available
subordinated amount of Class C notes is equal to the sum of:

  .   the aggregate nominal liquidation amount of all Class C notes of that
      series that will remain outstanding after giving effect to the
      repayment or cancellation of the Class C notes of that series to be
      repaid or canceled in that month;

  .   plus, the aggregate amount on deposit in the principal funding
      subaccounts for all Class C notes of that series after giving effect
      to the repayment or cancellation of all Class C notes that are to be
      repaid or cancelled in that month (other than receivables sales
      proceeds on deposit in those subaccounts);

  .   plus, the amount of Class A usage of Class C required subordinated
      amount in that series, as described in "Deposit and Application of
      Funds--Limit on Reallocations of Principal Collections from
      Subordinated Classes Taken to Benefit Senior Classes of Multiple
      Issuance Series."

    For determining whether Class C notes may be repaid or canceled while Class
B notes of the same series are outstanding, the remaining available
subordinated amount of Class C notes is equal to the sum of:

  .   the aggregate nominal liquidation amount of all Class C notes of that
      series that will remain outstanding after giving effect to the
      repayment or cancellation of the Class C notes of that series to be
      repaid or canceled in that month;

  .   plus, the aggregate amount on deposit in the principal funding
      subaccounts for all Class C notes of that series after giving effect
      to the repayment or cancellation of all Class C notes that are to be
      repaid or cancelled in that month (other than receivables sales
      proceeds on deposit in those subaccounts);

                                       75
<PAGE>

  .   plus, the amount of Class B usage of Class C required subordinated
      amount in that series, as described in "Deposit and Application of
      Funds--Limit on Reallocations of Principal Collections from
      Subordinated Classes Taken to Benefit Senior Classes of Multiple
      Issuance Series."

    There are exceptions to the limit on repayment of subordinated classes of a
multiple issuance series described in this subheading. These are when the
senior classes of notes have been prefunded as described in "Deposit and
Application of Funds--Targeted Deposits of Principal Collections to the
Principal Funding Account--Prefunding of the Principal Funding Account for
Senior Classes," when Class C notes are paid with funds available from the
applicable Class C reserve subaccount as described in "Deposit and Application
of Funds-- Withdrawals from the Class C Reserve Account" and when the
subordinated notes reach their legal maturity date.

    Subordinated notes that reach their expected principal payment date, or
that have an early redemption event, event of default or other optional or
mandatory redemption, will not be paid on the next following Monthly Principal
Date to the extent that they are necessary to provide the required subordinated
amount to senior classes of notes of the same series. If a class of
subordinated notes cannot be paid because of the subordination provisions of
the indenture, prefunding of the principal funding subaccounts for the senior
notes of the same series will begin, as described in "Deposit and Application
of Funds--Targeted Deposits of Principal Collections to the Principal Funding
Account." Thereafter, the subordinated notes will be paid on following Monthly
Principal Dates only if:

  .   enough notes of senior classes of that series are repaid so that the
      subordinated notes that are paid are no longer necessary to provide
      the required subordinated amount of the remaining senior notes; or

  .   new classes of subordinated notes of that series are issued so that
      the subordinated notes that are paid are no longer necessary to
      provide the required subordinated amount of the outstanding senior
      notes; or

  .   the principal funding accounts of the senior classes of notes of that
      series are prefunded so that none of the subordinated notes that are
      paid are necessary to provide the required subordinated amount for
      senior notes of the same series; or

  .   the subordinated notes reach their legal maturity date.

On the legal maturity date of a class of notes, all amounts on deposit in the
principal funding subaccount for that class, after giving effect allocations,
reallocations, deposits and sales of receivables, will be paid to the
noteholders of that class, even if payment would reduce the amount of
subordination protection below the required subordinated amount of the senior
classes of notes of that series. See "Deposit and Application of Funds--
Targeted Deposits of Principal Collections to the Principal Funding Account--
Prefunding of the Principal Funding Account for Senior Classes," "--Sale of
Credit Card Receivables" and "--Final Payment of Notes."

Limit on Allocations of Principal Collections of All Classes or Subclasses of
Notes

    No principal collections will be allocated to a class or subclass of notes
with a nominal liquidation amount of zero, even if the stated principal amount
of that class or subclass of notes has not been paid in full. However, any
funds in the applicable principal funding subaccount that are not reallocated
to other classes of that series, any funds in the applicable interest funding
subaccount, and in the case of Class C notes, any funds in the applicable Class
C reserve account, will still be available to pay principal of and interest on
that class of notes. If the nominal liquidation amount of a class of notes has
been reduced due to reallocation of principal collections to pay interest on
senior classes of notes or charge-offs of principal receivables in the master
trust, it is possible for that class's nominal liquidation amount to be
increased by allocations of Excess Finance Charge Collections.

Targeted Deposits to the Class C Reserve Account

    The Class C reserve account will initially not be funded. The Class C
reserve account will not be funded unless and until finance charge collections
generated by the master trust fall below a level specified in the applicable
supplement to this prospectus. The Class C reserve account will be funded each
month, as necessary, from finance charge collections allocated to the
collateral certificate that month after payment of fees and expenses of the
master trust servicer and the indenture trustee, targeted deposits to the
interest funding account, reimbursement of charge-offs of principal receivables
in the master trust that are allocated to the collateral certificate and
reimbursement of any deficits in the nominal liquidation amounts of the notes.

    The aggregate deposit to be made to the Class C reserve account in each
month from finance charge collections will be the sum of Class C reserve
account deposits targeted to be made for each class or subclass of Class C
notes. The amount of that deposit and the circumstances that require that
deposit to be made will be set forth in the applicable supplement to this
prospectus.

    If the aggregate deposit made to the Class C reserve account is less than
the sum of the targeted deposits for each class of Class C notes, then the
amount available will first be allocated to each class that requires a deposit
pro rata based on the ratio of the nominal liquidation amount of that class to
the aggregate nominal liquidation amount of all Class C notes that have a
targeted deposit. Any amount in excess of the amount targeted to be deposited
to the Class C reserve subaccount for any class of notes will be reallocated to
classes of notes that did not receive their targeted deposits as a result of
the initial allocation on the same basis until all available funds are applied.

    In addition, if a new issuance of notes of a multiple issuance series
results in an increase in the funding deficit of the Class C reserve account
for any subclass of Class C notes of that series, the issuer will make a cash
deposit to that Class C reserve account in the amount of that increase. See
"The Notes--Issuance of New Series, Classes and Subclasses of Notes."

                                       77
<PAGE>

Withdrawals from the Class C Reserve Account

    Withdrawals will be made from the Class C reserve subaccounts, but in no
event more than the amount on deposit in the applicable Class C reserve
subaccount, in the following order:

  .   Interest, Payments with Respect to Derivative Agreements for Interest
      and Accretion on Discount Notes. If the amount on deposit in the
      interest funding subaccount for any class or subclass of Class C notes
      is insufficient to pay in full the amounts for which withdrawals are
      required, the amount of the deficiency will be withdrawn from the
      applicable Class C reserve subaccount and deposited into the
      applicable interest funding subaccount.

  .   Payments of Principal and Payments with Respect to Derivative
      Agreements for Principal. If the amount on deposit in the principal
      funding subaccount for any class or subclass of Class C notes is
      insufficient to pay in full the amounts for which withdrawals are
      required, an amount equal to the lesser of (i) the amount of the
      deficiency and (ii) the amount by which the nominal liquidation amount
      of the class or subclass of Class C notes plus funds on deposit in the
      applicable Class C principal funding subaccount is less than the
      outstanding dollar principal amount of the subclass of Class C notes
      will be withdrawn from the applicable Class C reserve subaccount and
      deposited into the applicable principal funding subaccount.

  .   Amounts Treated as Finance Charge Collections. If at any time the
      amount on deposit in a Class C reserve subaccount is greater than the
      required amount, the excess will be withdrawn and treated as finance
      charge collections. In addition, after payment in full of any class or
      subclass of Class C notes, any amount remaining on deposit in the
      applicable Class C reserve subaccount will be withdrawn and treated as
      finance charge collections.

Sale of Credit Card Receivables

    If a class of notes has an event of default and is accelerated before its
legal maturity date, the master trust may sell credit card receivables--or an
interest in credit card receivables--if the conditions described in "Covenants,
Events of Default and Early Redemption Events--Events of Default" are
satisfied. This sale will take place at the option of the indenture trustee or
at the direction of the holders of a majority of aggregate outstanding dollar
principal amount of notes of that class. Those majority holders will also have
the power to determine the time of the sale, except that any sale of
receivables for a subordinated class of notes will be delayed until the senior
classes of notes of the same series are prefunded to such an extent that the
proceeds of the receivables are sufficient to provide the required
subordination protection for the non-prefunded portion of the senior classes of
that series. If principal of or interest on a class of notes has not been paid
in full on the legal maturity date, the sale will automatically take place on
that date. There may be only one sale of credit card receivables for each class
of notes.

    The amount of credit card receivables sold will be up to 110% of the
nominal liquidation amount of the class of notes that directed the sale to be
made. The proceeds of the sale of receivables will be deposited into the
principal funding account for the applicable

                                       78
<PAGE>

class up to the outstanding dollar principal amount of the applicable class.
Any excess will be deposited into the interest funding subaccount for that
class, to be applied to future payments of interest and to reimburse
withdrawals of proceeds of the sale of receivables from the principal funding
subaccount of that class.

    In the case of any accelerated class of Class A notes, or any class of
notes that has reached its legal maturity date, or any class of notes that is
not prevented from being repaid by virtue of the subordination provisions of
the indenture, the master trust will sell either an ownership interest in
specific principal receivables and finance charge receivables, or an amortizing
undivided interest in the pool of receivables in the master trust. In any other
case, the master trust will sell a undivided interest in the pool of
receivables in the master trust that is initially a revolving undivided
interest in the pool of receivables in the master trust, that then converts
either to an ownership interest in specific receivables or to an amortizing
undivided interest in receivables. In this case, the undivided interest would
revolve from the date of the sale until the earlier of the legal maturity date
of the affected class of notes and the date when the affected class of notes is
not prevented from being paid by the subordination provisions of the indenture.
While an undivided interest is revolving, the principal collections allocated
to it by the master trust will be treated as principal collections that are
allocated to the notes and applied as described in item second under "--
Allocation of Principal Collections to Accounts" or reinvested in credit card
receivables in the master trust. In the case of an amortizing undivided
interest, the principal collections allocated to it by the master trust will be
paid to the purchaser, and will not be available to noteholders or reinvested.
For both revolving and amortizing undivided interests, the finance charge
collections allocated to the undivided interest will be paid to the purchaser,
and will not be available to the noteholders. Both revolving and amortizing
undivided interests will be reduced by a pro rata allocation of charged-off
credit card receivables in the master trust.

    The nominal liquidation amount of the class of notes that directed the sale
to be made will be automatically reduced to zero. No more principal collections
will be allocated to that class.

    The only sources of funds to pay principal of a class of notes that has
directed a sale of credit card receivables will be the proceeds of the sale of
receivables, receipts under derivative agreements, funds available in any
applicable reserve account and funds available under item third under "--
Allocation of Finance Charge Collections to Accounts" to reimburse amounts
withdrawn from the principal funding subaccount of that class to provide
subordination protection for senior classes of the same series. That class will
not receive any further distributions of principal collections under the
collateral certificate. Interest on that class of notes will be paid only with
funds on deposit in that class's interest funding subaccount, investment
earnings on funds in that class's principal funding subaccount, receipts under
any derivative agreement and funds available in any applicable reserve account.

    If Class A notes direct a sale of credit card receivables to be made, the
proceeds will be paid out on the next Monthly Principal Date following the date
of the sale. However, proceeds of a sale directed by a subordinated class of
notes will not be paid before the legal

                                       79
<PAGE>

maturity date of that class, to the extent those notes are necessary to provide
the required subordinated amount of a senior class of notes of the same series.
If a class of notes cannot be paid because of the subordination provisions of
the indenture, prefunding of the principal funding subaccounts for the senior
notes of the same series--which will have begun when the subordinated class had
its event of default--will continue as described in "--Targeted Deposits of
Principal Collections to the Principal Funding Account." Thereafter,
receivables sales proceeds will be paid to the applicable noteholders when the
subordination provisions of the indenture permit, or on the legal maturity date
of the applicable notes. On the legal maturity date of a subordinated class of
notes, any funds on deposit in that class's principal funding subaccount will
be paid to the noteholders of that class, even if payment would reduce the
amount of subordination protection below the required subordinated amount of
the senior classes of that series.

    So long as the proceeds of sales of credit card receivables are on deposit
in the principal funding subaccount for a subordinated class of notes, those
funds will be treated like principal collections for purposes of reallocations
to pay interest on senior classes of notes, or to reimburse charge-offs of
principal receivables in the master trust, to the extent that the nominal
liquidation amount of that class would have been available for the same
purposes. The proceeds of sales of credit card receivables on deposit in the
principal funding subaccount for a subordinated class of notes will not be
reallocated to the principal funding subaccount for a senior class if the
senior classes of notes of that series have reached their expected principal
payment date, or have an early redemption event, event of default or other
optional or mandatory redemption, or require prefunding, or for the other
purposes described under the heading "--Targeted Deposits of Principal
Collections to the Principal Funding Account."

    If a class of notes directs a sale of credit card receivables, then that
class will no longer be entitled to subordination protection from subordinated
classes of notes of the same series. However, the proceeds of the sale of
credit card receivables on deposit in the principal funding subaccount for a
subordinated class of notes continue to provide subordination protection to the
senior classes of notes of the same series until the legal maturity date of the
subordinated class of notes.

    Classes of notes that have directed sales of credit card receivables are
generally not considered to be outstanding under the indenture, including for
purposes of

  .   allocations of finance charge collections and principal collections,

  .   computing the required subordinated amount available for new issuances
      of senior notes of a multiple issuance series, and

  .   computing Surplus Finance Charge Collections and the weighted average
      interest rate of the notes.

    After giving effect to a sale of receivables for a class of notes, the
amount of proceeds on deposit in a principal funding subaccount may be less
than the outstanding dollar principal amount of that class. This deficiency can
arise because the nominal liquidation

                                       80
<PAGE>

amount of that class was reduced before the sale of receivables or if the sale
price for the receivables was low. These types of deficiencies will not be
reimbursed. A deficiency can also arise if proceeds on deposit in a
subordinated class's principal funding subaccount have been reallocated to pay
interest on senior classes of notes or reimburse charge-offs of principal
receivables in the master trust. Until the legal maturity date of a class of
notes, finance charge collections under item third under "--Allocation of
Finance Charge Collections to Accounts" that are available to reimburse
reductions in the nominal liquidation amount of the notes will be shared pro
rata to reimburse this kind of deficiency.

Final Payment of the Notes

    Noteholders will not be entitled to payment of principal, or in the case of
foreign currency notes, to have any payment made by the issuer under a
derivative agreement with respect to principal, in excess of the highest
outstanding dollar principal amount of that class

  .   minus, any unreimbursed reductions in the nominal liquidation amount
      of that class from charge-offs of principal receivables in the master
      trust;

  .   minus, any unreimbursed reallocations of principal collections to pay
      interest on senior classes of notes; and

  .   plus, in the case of classes of Class C notes, funds in the applicable
      Class C reserve account.

    As an exception to this rule, the proceeds of a sale of receivables
following acceleration or on the legal maturity date of a class of notes will
be available to the extent necessary to pay the outstanding dollar principal
amount of that class on the date of the sale.

    A class of notes will be considered to be paid in full, the holders of
those notes will have no further right or claim, and the issuer will have no
further obligation or liability for principal or interest, on the earliest to
occur of

  .   the date of the payment in full of the stated principal amount of and
      all accrued interest on that class of notes;

  .   the date on which the outstanding dollar principal amount of that
      class of notes is reduced to zero, and all accrued interest on that
      class of notes is paid in full; or

  .   on the legal maturity date of that class of notes, after giving effect
      to all deposits, allocations, reallocations, sales of credit card
      receivables and payments to be made on that date.

Pro Rata Payments Within a Class or Subclass

    With respect to single issuance series, all notes of a class will receive
payments of principal and interest pro rata based on the outstanding dollar
principal amount of each note in that class. With respect to multiple issuance
series, all notes of a subclass will receive payments of principal and interest
pro rata based on the outstanding dollar principal amount of each note in that
subclass.

                        COVENANTS, EVENTS OF DEFAULT AND
                            EARLY REDEMPTION EVENTS

Issuer Covenants

    The issuer will not, among other things

  .   except as expressly permitted by the indenture or related documents,
      sell, transfer, exchange or otherwise dispose of any of the assets of
      the issuer that constitutes collateral for the notes, unless directed
      to do so by the indenture trustee,

  .   claim any credit on or make any deduction from the principal and
      interest payable on the notes, other than amounts withheld under the
      Internal Revenue Code or other applicable tax law,

  .   voluntarily dissolve or liquidate, or

  .   permit (A) the validity or effectiveness of the indenture to be
      impaired or permit any person to be released from any covenants or
      obligations with respect to the notes under the indenture except as
      may be expressly permitted by the indenture, (B) any lien, charge,
      excise, claim, security interest, mortgage or other encumbrance to be
      created on or extend to or otherwise arise upon or burden the
      collateral for the notes or proceeds thereof except as may be created
      by the terms of the indenture or (C) the lien of the indenture not to
      constitute a valid security interest in the assets of the issuer that
      secure the notes.

    The issuer may not engage in any activity other than the activities
specified under "The Issuer." The issuer will not incur, assume or guarantee
any indebtedness for borrowed money other than indebtedness incurred on the
notes and under the indenture.

Events of Default

    Each of the following events is an "event of default" for any class of
notes:

  .   the issuer's failure, uncured after five business days, to pay
      interest on any note of that class when due;

  .   the issuer's failure to pay the stated principal amount of any note of
      that class on its legal maturity date;

  .   the issuer's default in the performance, or breach, of any other of
      its covenants or warranties in the indenture, uncured 60 days after
      written notice by the indenture trustee or by the holders of 10% of
      the aggregate outstanding dollar principal amount of the outstanding
      notes of the affected class--other than a covenant or warranty
      included in the indenture solely for the benefit of series or classes
      of

                                       82
<PAGE>

      notes other than that particular class--and that default or breach is
      materially adverse to those noteholders;

  .   the occurrence of some events of bankruptcy, insolvency or
      reorganization of the issuer; and

  .   any additional events of default specified in the applicable
      supplement to this prospectus for that class.

    Failure to pay the full stated principal amount of a note on its expected
principal payment date will not constitute an event of default. An event of
default with respect to one class of notes will not necessarily be an event of
default with respect to any other class of notes.

    The occurrence of some events of default involving the bankruptcy or
insolvency of the issuer results in an automatic acceleration of all of the
notes. If other events of default occur and are continuing with respect to any
class, either the indenture trustee or the holders of more than 50% in
aggregate outstanding dollar principal amount of the notes of that class may
declare the principal of all those outstanding notes to be immediately due and
payable. This declaration of acceleration may generally be rescinded by the
holders of a majority in aggregate outstanding dollar principal amount of
outstanding notes of that class.

    If a class of notes is accelerated before its legal maturity date, the
indenture trustee may at any time thereafter, and at the direction of the
holders of a majority of aggregate outstanding dollar principal amount of Notes
of that class at any time thereafter will, direct the master trust to sell
credit card receivables as described in "Deposit and Application of Funds--Sale
of Credit Card Receivables," but only if at least one of the following
conditions is met:

  .   90% of the holders of the accelerated class of notes consent; or

  .   the proceeds of the sale would be sufficient to pay all outstanding
      amounts due on the accelerated class of notes; or

  .   the indenture trustee determines that the funds to be allocated to the
      accelerated class of notes, taking into account finance charge
      collections and principal collections allocable to the collateral
      certificate, payments to be received under derivative agreements and
      amounts on deposit in the applicable principal funding subaccount and
      interest funding subaccount and, in the case of Class C notes, the
      applicable Class C reserve subaccount is not likely to be sufficient
      to make payments on the accelerated notes when due, and the holders of
      two-thirds of the aggregate outstanding principal dollar amount of
      notes of the accelerated class consent to the sale.

If net sale proceeds of the credit card receivables would be less than the
nominal liquidation amount of accelerated subordinated notes, prefunding of the
principal funding subaccounts for the senior classes will begin and continue
until the principal funding subaccounts have been prefunded to the extent
necessary to permit the sale of the applicable credit card receivables and
deposit of proceeds of the sale to the principal funding subaccount for the

                                       83
<PAGE>

subordinated class. See "Deposit and Application of Funds--Targeted Deposits of
Principal Collections to the Principal Funding Account--Prefunding of the
Principal Funding Account for Senior Classes." The sale of credit card
receivables will be delayed until the prefunding is complete or until the legal
maturity date of the accelerated notes.

    In addition, as a condition to a sale of an undivided interest in
receivables rather than an absolute ownership, the indenture trustee must
obtain appropriate tax opinions.

    If a sale of credit card receivables does not take place following an
acceleration of a class of notes, then:

  .   The issuer will continue to hold the collateral certificate, and
      distributions on the collateral certificate will continue to be
      applied in accordance with the distribution provisions of the
      indenture.

  .   Principal and interest will be paid monthly on the accelerated class
      of notes to the extent funds are received from the master trust and
      available to the accelerated class after giving effect to all
      allocations and reallocations and to the extent payment is permitted
      by the subordination provisions of the accelerated class.

  .   If the accelerated notes are of a subordinated class, and
      subordination requirements prevent the payment of the accelerated
      subordinated class, prefunding of the senior classes of that series
      will begin, as described in "--Targeted Deposits of Principal
      Collections to the Principal Funding Account." Thereafter, payment
      will be made to the extent described in "Deposit and Application of
      Funds--Limit on Repayments of Subordinated Classes of Single Issuance
      Series" and "Limit on Repayments of Subordinated Classes of Multiple
      Issuance Series."

  .   On the legal maturity date of the accelerated notes, if the notes have
      not been paid in full and if the notes have a nominal liquidation
      amount in excess of zero, the indenture trustee will direct the master
      trust to sell credit card receivables as described under "Deposit and
      Application of Funds--Final Payment of the Notes."

    The holders of a majority in aggregate outstanding dollar principal amount
of any accelerated class of notes have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the indenture
trustee, or exercising any trust or power conferred on the indenture trustee.
However, this right may be exercised only if the direction provided by the
noteholders does not conflict with applicable law or the indenture or have a
substantial likelihood of involving the indenture trustee in personal
liability.

    Generally, if an event of default occurs and any notes are accelerated, the
indenture trustee is not obligated to exercise any of its rights or powers
under the indenture unless the holders of affected notes offer the indenture
trustee reasonable indemnity. Upon acceleration of the maturity of a series or
class of notes following an event of default, the indenture trustee will have a
lien on the collateral for those notes ranking senior to the lien of those
notes for its unpaid fees and expenses.


                                       84
<PAGE>

    If an event of default occurs consisting of failure to pay principal of or
interest on a class of notes in full on the legal maturity date, the issuer
will automatically direct the master trust to sell credit card receivables on
that date, as described in "Deposit and Application of Funds--Sale of Credit
Card Receivables."

    The indenture trustee has agreed, and the noteholders will agree, that they
will not at any time institute against the issuer, the Banks or the master
trust any bankruptcy, reorganization or other proceeding under any federal or
state bankruptcy or similar law.

Early Redemption Events

    The issuer is required to redeem in whole or in part, to the extent that
funds are available for that purpose, any class of notes of a series upon the
occurrence of an early redemption event with respect to that class. Early
redemption events include the following:

  .   the occurrence of a note's expected principal payment date;

  .   each of the early amortization events applicable to the collateral
      certificate, as described under "The Master Trust--Early Amortization
      Events";

  .   mandatory prepayment of the entire collateral certificate resulting
      from a breach of a representation or warranty by the Banks under the
      pooling and servicing agreement;

  .   the amount of Surplus Finance Charge Collections averaged over any
      three consecutive months being less than the Required Surplus Finance
      Charge Amount for the most recent month;

  .   with respect to any subclass of notes, at any time when the issuer has
      requested the master trust to make a payment of principal collections
      to the principal funding subaccount for that subclass of notes, the
      Portfolio Yield for any month is less than the weighted average
      interest rates for all notes of the same group as of the last day of
      the month, taking into account all net payments to be made or received
      under Performing derivative agreements;

  .   the issuer becoming an "investment company" within the meaning of the
      Investment Company Act of 1940, as amended;

  .   with respect to any subclass of notes that has funds on deposit in its
      principal funding subaccount on the last day of any month, other than
      any proceeds of the sale of receivables as described under "Deposit
      and Application of Funds--Sale of Credit Card Receivables," the amount
      of the designated sellers' interest described under "Deposit and
      Application of Funds--Deposit of Principal Funding Subaccount Earnings
      in Interest Funding Subaccounts; Principal Funding Subaccount Earnings
      Shortfall" is less than the aggregate amount of those principal
      funding subaccount deposits; or

  .   any additional early redemption event specified in a supplement to
      this prospectus.


                                       85
<PAGE>

    The redemption price of a note so redeemed will be the outstanding dollar
principal amount of that note, plus accrued interest--or, in the case of
discount notes, principal accreted--but unpaid on that note to but excluding
the date of redemption, which will be the next Monthly Principal Date. If the
amount of principal collections and finance charge collections of credit card
receivables allocable to the class of notes to be redeemed, together with funds
on deposit in the applicable principal funding subaccount, interest funding
subaccount and Class C reserve account are insufficient to pay the redemption
price in full on the next Monthly Principal Date after giving effect to
subordination and allocations to any other notes ranking equally with that
note, monthly payments on the notes to be redeemed will thereafter be made on
each Monthly Principal Date until the stated principal amount of the notes plus
all accrued and unpaid interest is paid in full, or the legal maturity date of
the notes occurs, whichever is earlier.

    No principal collections will be allocated to a class of notes with a
nominal liquidation amount of zero, even if the stated principal amount of that
class has not been paid in full. However, any funds in the applicable principal
funding subaccount that are not reallocated to other classes of that series,
and any funds in the applicable interest funding subaccount and Class C reserve
account will still be available to pay principal of and interest on that class
of notes. In addition, if Excess Finance Charge Collections are available, they
can be applied to reimburse reductions in the nominal liquidation amount of
that class resulting from reallocations of principal collections to pay
interest on senior classes of notes, or from charge-offs of principal
receivables in the master trust.

    Payments on redeemed notes will be made in the same priority as described
in "The Notes--Subordination of Principal." The issuer will give notice to
holders of the affected notes before an early redemption date.

                        MEETINGS, VOTING AND AMENDMENTS

Meetings

    The indenture trustee may call a meeting of the holders of notes of a
series or class at any time. The indenture trustee will call a meeting upon
request of the issuer or the holders of at least 10% in aggregate outstanding
dollar principal amount of the outstanding notes of the series or class. In any
case, a meeting will be called after notice is given to holders of notes in
accordance with "Notices and Reports--Notices."

    The quorum for a meeting is a majority of the holders of the outstanding
dollar principal amount of the notes, the series of notes or the class of notes
that is to have the meeting, as the case may be, unless a higher percentage is
specified for approving action taken at the meeting, in which case the quorum
is the higher percentage.

Voting

    Any action or vote to be taken by the holders of a majority or larger
specified percentage of the notes, any series of notes or any class of notes
may be adopted by the

                                       86
<PAGE>

affirmative vote of the holders of a majority or the applicable larger
specified percentage in aggregate outstanding dollar principal amount of the
outstanding notes, of that series or of that class, as the case may be.

    Any action or vote taken at any meeting of holders of notes duly held in
accordance with the indenture will be binding on all holders of the affected
notes or the affected series or class of notes, as the case may be.

    Notes held by the issuer, either Bank, or their affiliates will not be
deemed outstanding for purposes of voting or calculating quorum at any meeting
of noteholders.

Amendments to the Pooling and Servicing Agreement

    The Banks and the master trust trustee may amend the pooling and servicing
agreement and any supplement to that agreement without the consent of the
master trust investor certificateholders so long as the master trust trustee
receives an opinion of counsel that the amendment will not materially adversely
affect the interests of the investor certificateholders and the rating agencies
confirm that the amendment will not cause the rating assigned to any
outstanding series or class to be withdrawn or reduced. Accordingly, neither
the issuer nor any holder of any note will be entitled to vote on any such
amendment.

    The pooling and servicing agreement and any supplement to that agreement
may also be amended with the consent of master trust investor
certificateholders holding not less than 66 2/3% of the aggregate outstanding
dollar principal amount of the investor certificates of all adversely affected
series for the purpose of adding, changing or eliminating any provisions of the
agreement or any supplement or of modifying the rights of those investor
certificateholders. However, no amendment may

  .   reduce the amount of, or delay the timing of, any distribution to be
      made to investor certificateholders or the amount available under any
      series enhancement without the consent of each affected investor
      certificateholder,

  .   change the definition or the manner of calculating the interest of any
      investor certificate without the consent of each affected investor
      certificateholder,

  .   reduce the percentage of investor certificateholders required to
      consent to any amendment without the consent of each investor
      certificateholder, or

  .   adversely affect the rating of any series or class of investor
      certificates without the consent of investor certificateholders
      holding not less than 66 2/3% of the aggregate outstanding dollar
      principal amount of that series or class.

    For purposes of any vote or consent under the pooling and servicing
agreement

  .   that requires the consent or vote of each holder of a master trust
      investor certificate, each holder of a note will be treated as a
      holder of an investor certificate under the pooling and servicing
      agreement;

  .   that requires the consent or vote of any series of investor
      certificates, each series of notes will be treated as a series of
      investor certificates under the pooling and servicing agreement;

                                       87
<PAGE>

  .   that requires the consent or vote of any class of investor
      certificates, each class of notes of a single issuance series and each
      subclass of notes of a multiple issuance series will be treated as a
      class of investor certificates under the pooling and servicing
      agreement; and

  .   any notes owned by the Issuer, the Banks or any of their affiliates
      will be deemed not to be outstanding.

Amendments to the Indenture

    The issuer and the indenture trustee may modify and amend the indenture or
any supplemental indenture with the consent of the holders of not less than a
majority in aggregate dollar principal amount of the outstanding notes of each
series affected by that modification or amendment. However, if the modification
or amendment would result in any of the following events occurring, it may be
made only with the consent of the holders of each outstanding note affected by
the modification or amendment:

  .   a change in any date scheduled for the payment of interest on any
      note, the expected principal payment date or legal maturity date of
      any note, or the date determined for any mandatory or optional
      redemption of any note;

  .   a reduction of the stated principal amount, outstanding dollar
      principal amount or nominal liquidation amount of, or interest rate
      on, any note;

  .   an impairment of the right to institute suit for the enforcement of
      any payment on any note;

  .   a reduction of the percentage in outstanding dollar principal amount
      of notes of any series or class, the consent of whose holders is
      required for modification or amendment of the indenture or any
      supplemental indenture or for waiver of compliance with provisions of
      the indenture or supplemental indenture or for waiver of defaults;

  .   permission is given to create any lien ranking senior to the lien of
      the indenture or terminate the lien of the indenture;

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

  .   a change in the method of computing the amount of principal of, or
      interest on, any note on any date.

    The issuer and the indenture trustee may also amend, supplement or
otherwise modify the indenture without the consent of any noteholders in any
manner that would not adversely affect, in any material respect, the interests
of the noteholders, including for purposes of curing ambiguities, making minor
corrections, and providing for the new issuances of notes. In addition, without
the consent of any noteholders, the issuer may amend the indenture to change
the amount of required or available subordination available for any class of
notes of a multiple issuance series, or the method of computing the amount of
that subordination, so long as the issuer has received confirmation from the
rating agencies that the change will not result in the rating assigned to any
outstanding notes to be withdrawn or reduced.

                                       88
<PAGE>

    The holders of a majority in aggregate outstanding dollar principal amount
of the notes of a series may waive, on behalf of the holders of all the notes
of that series, compliance by the issuer with specified restrictive provisions
of the indenture.

    The holders of a majority in aggregate outstanding dollar principal amount
of the notes of an affected series or class may, on behalf of all holders of
notes of that series or class, waive any past default under the indenture with
respect to notes of that series or class. However, the consent of the holders
of all outstanding notes of a class is required to waive any past default in
the payment of principal of, or interest on, any note of that class or in
respect 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
class.

Amendments to the Trust Agreement

    The Banks and the issuer trustee may amend the trust agreement without the
consent of the noteholders so long as the indenture trustee receives an opinion
of counsel that the amendment will not adversely affect in any material respect
the interests of the noteholders and the rating agencies confirm that the
amendment will not cause the rating assigned to any outstanding series or class
of notes to be withdrawn or reduced. Accordingly, neither the indenture trustee
nor any holder of any note will be entitled to vote on any such amendment.

    The trust agreement may also be amended with the consent of noteholders
holding not less than 66 2/3% of the aggregate outstanding dollar principal
amount of the notes of all adversely affected series for the purpose of adding,
changing or eliminating any provisions of the agreement or of modifying the
rights of those investor certificateholders.

Tax Opinions for Amendments

    No amendment to the indenture, the pooling and servicing agreement or the
trust agreement will be effective unless the issuer has delivered to the
indenture trustee and the rating agencies an opinion of counsel that:

  .   for federal and South Dakota income and franchise tax purposes (1) the
      amendment will not adversely affect the characterization as debt of
      any outstanding series or class of master trust investor certificates
      issued by the master trust, other than the collateral certificate, (2)
      the amendment will not cause a taxable event to holders of master
      trust investor certificates, and (3) following the amendment, the
      master trust will not be an association, or publicly traded
      partnership, taxable as a corporation; and

  .   for federal and Delaware income and franchise tax purposes (1) the
      amendment will not adversely affect the characterization of the notes
      of any outstanding series or class as debt, (2) the amendment will not
      cause a taxable event to holders of any outstanding notes, and (3)
      following the amendment, the issuer will not be an association, or
      publicly traded partnership, taxable as a corporation.

                              NOTICES AND REPORTS

Addresses for Notices

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

Issuer's Annual Compliance Statement

    The issuer is required to furnish annually to the indenture trustee a
statement concerning its performance or fulfillment of covenants, agreements or
conditions in the indenture as well as the presence or absence of defaults
under the indenture.

Indenture Trustee's Annual Report

    The indenture trustee is required to mail each year to all registered
noteholders a report concerning

  .   its eligibility and qualifications to continue as trustee under the
      indenture,

  .   any amounts advanced by it under the indenture,

  .   the amount, interest rate and maturity date or indebtedness owing by
      the issuer to it in the indenture trustee's individual capacity,

  .   the property and funds physically held by it as indenture trustee,

  .   any release or release and substitution of collateral subject to the
      lien of the indenture that has not previously been reported, and

  .   any action taken by it that materially affects the notes and that has
      not previously been reported.

List of Noteholders

    Three or more holders of notes of any series, each of whom has owned a note
for at least six months, may, upon written request to the indenture trustee,
obtain access to the current list of noteholders of the issuer for purposes of
communicating with other noteholders concerning their rights under the
indenture or the notes. The indenture trustee may elect not to give the
requesting noteholders access to the list if it agrees to mail the desired
communication or proxy to all applicable noteholders.

Reports

    Monthly reports containing information on the notes and the collateral
securing the notes will be filed with the Securities and Exchange Commission.
These reports will not be sent to noteholders. See "Where You Can Find
Additional Information" for information as to how these reports may be
accessed.

                                       90
<PAGE>

    On or before January 31 of each calendar year, the paying agent, on behalf
of the indenture trustee, will furnish to each person who at any time during
the prior calendar year was a noteholder of record a statement containing the
information required to be provided by an issuer of indebtedness under the
Internal Revenue Code. See "Tax Matters."

                               THE MASTER TRUST

    Citibank Credit Card Master Trust I is a New York common law trust formed
by Citibank (South Dakota) and Citibank (Nevada) in May 1991 to securitize a
portion of their portfolios of credit card receivables. Other affiliates of
the Banks may in the future sell credit card receivables to the master trust.

    The master trust is operated pursuant to a pooling and servicing agreement
among Citibank (South Dakota), as seller and servicer, Citibank (Nevada), as
seller, and Bankers Trust Company, as trustee.

    The master trust does not engage in any activity other than acquiring and
holding trust assets and the proceeds of those assets, issuing series of
investor certificates, making distributions and related activities.

    The master trust has no employees and does not conduct unrelated business
activities.

Master Trust Assets

    The master trust assets consist primarily of credit card receivables
arising in a portfolio of revolving credit card accounts that meet the
eligibility requirements specified in the pooling and servicing agreement, and
collections on the accounts. The Banks sell and assign the credit card
receivables to the master trust. The receivables arise in accounts that are
generated under MasterCard International or VISA programs. The accounts are
originated by Citibank (South Dakota) or purchased by it from other credit
card issuers.

    The credit card accounts are owned by Citibank (South Dakota) but a
participation in the credit card receivables in some of the accounts have been
sold to Citibank (Nevada) before their conveyance to the master trust. The
accounts have been selected from substantially all of the eligible accounts in
Citibank (South Dakota)'s credit card portfolio. Eligible accounts are credit
card accounts owned by Citibank (South Dakota) that

  .   are in existence and maintained by Citibank (South Dakota),

  .   are payable in U.S. dollars,

  .   in the case of the initial accounts designated to the master trust,
      have a cardholder with a billing address located in the United States
      or its territories or possessions or a military address,


                                      91
<PAGE>

  .   have a cardholder who has not been identified as being involved in a
      voluntary or involuntary bankruptcy proceeding,

  .   have not been identified as an account with respect to which the
      related card has been lost or stolen,

  .   have not been sold or pledged to any other party,

  .   do not have receivables that have been sold or pledged to any other
      party, and

  .   in the case of the initial accounts designated to the master trust,
      are MasterCard or VISA revolving credit card accounts.

Citibank (South Dakota) believes that the accounts are representative of the
eligible accounts in its portfolio and that the inclusion of the accounts, as a
whole, does not represent an adverse selection by it from among the eligible
accounts. See "The Master Trust Receivables and Accounts" attached as Annex I
to the supplement to this prospectus for financial information on the
receivables and the accounts.

    The Banks are compensated for the transfer of the credit card receivables
to the master trust from two sources: (1) the net cash proceeds received by the
Banks, as owners of the sellers' interest, from the sale to third party
investors of certificates representing beneficial ownership interests in
receivables held through the master trust and (2) the increase in the amount of
the sellers' interest, which represents the beneficial interest in the pool of
receivables retained by the Banks and not sold to third party investors.

    The Banks may, at their option, designate additional credit card accounts
to the master trust, the receivables in which will be sold and assigned to the
master trust. This type of designation is referred to as a "lump addition."
Since the creation of the master trust, the Banks have made lump additions and
may make lump additions in the future.

    In addition, the Banks are required to make a lump addition if as of the
end of any calendar week the total amount of principal receivables in the
master trust is less than the amount required by the rating agencies that rate
the certificates purchased by the investors. After a required lump addition,
the total amount of principal receivables in the master trust will be at least
equal to the required amount. A lump addition consists of

  .   credit card receivables arising in eligible accounts in Citibank
      (South Dakota)'s credit card portfolio,

  .   credit card receivables arising in portfolios of revolving credit card
      accounts acquired by the Banks from other credit card issuers,

  .   credit card receivables arising from nonpremium and premium MasterCard
      and VISA credit card accounts previously transferred by the Banks to
      other trusts formed by the Banks that have reached their maturity
      dates,

  .   credit card receivables arising in any other revolving credit card
      accounts of a type that has previously not been included in the
      accounts, and

  .   participations representing undivided interests in a pool of assets
      primarily consisting of revolving credit card accounts and collections
      on those accounts.

                                       92
<PAGE>

    The Banks may also designate newly originated credit card accounts--or "new
accounts"--to be included as accounts, if they meet the conditions in the
pooling and servicing agreement. The number of new accounts designated for any
quarterly period may not exceed 15% of the number of accounts as of the first
day of that period, and the number of new accounts designated during any
calendar year may not exceed 20% of the number of accounts as of the first day
of that calendar year, unless the rating agencies otherwise consent. Since the
creation of the master trust, the Banks have designated new accounts and the
Banks may continue to do so in the future.

    Credit card accounts designated to the master trust in the future may have
different eligibility criteria from those used in selecting the initial
accounts and may not be accounts of the same type previously included in the
master trust. Therefore, we cannot provide any assurance that additional
accounts will be of the same credit quality as the accounts currently
designated to the master trust. These additional accounts may contain
receivables that consist of fees, charges and amounts that are different from
the fees, charges and amounts applicable to the accounts previously designated
to the master trust. These additional accounts may also have different credit
limits, balances and ages. In addition, the inclusion in the master trust of
additional accounts with lower periodic finance charges may reduce the
Portfolio Yield of the master trust receivables. The Banks intend to file with
the Securities and Exchange Commission, on behalf of the master trust, a
Current Report on Form 8-K with respect to any addition of accounts that would
have a material effect on the composition of the accounts.

    The Banks may remove the receivables in some of the credit card accounts,
if they meet the conditions in the pooling and servicing agreement. These
conditions include:

  .   the rating agencies confirm that the removal will not cause the rating
      assigned to any outstanding series or class of master trust investor
      certificates to be withdrawn or reduced, and

  .   the Banks deliver an officers' certificate that the Banks reasonably
      believe that the removal will not (1) cause an early amortization
      event or a reduction of the amount of finance charge collections for
      any series of master trust investor certificates below the level
      required by the rating agencies that have rated the certificates
      issued by the master trust or (2) adversely affect the amount or
      timing of payments to investor certificateholders of any series.

    Citibank (South Dakota), as owner of the credit card accounts, has the
right to change or terminate any terms, conditions, services or features of the
accounts, including increasing or decreasing periodic finance charges or
minimum payments.

    Citibank (South Dakota) has agreed that, except as otherwise required by
law or it deems necessary to maintain its credit card business on a competitive
basis, it will not take actions that reduce the Portfolio Yield on the
receivables in the master trust to be less than the sum of


                                       93
<PAGE>

  .   the weighted average certificate rate of each class of investor
      certificates of each series, and

  .   the weighted average of the net servicing fee rate allocable to each
      class of investor certificates of each series.

    In addition, Citibank (South Dakota) has agreed that, unless required by
law, it will not reduce the Portfolio Yield to less than the highest
certificate rate for any outstanding series or class of master trust investor
certificates. Citibank (South Dakota) has also agreed that it will change the
terms relating to the credit card accounts designated to the master trust only
if that change is made applicable to a comparable segment of the portfolio of
accounts with similar characteristics owned or serviced by Citibank (South
Dakota), and not only to the accounts designated to the master trust.

    On the issuance date for a series of master trust investor certificates the
Banks make representations and warranties to the master trust relating to the
credit card receivables and accounts, including the following:

  .   each account was an eligible account generally as of the date the
      receivables arising in that account were initially conveyed to the
      master trust,

  .   each of the receivables then existing in the accounts is an eligible
      receivable, and

  .   as of the date of creation of any new receivable, that receivable is
      an eligible receivable.

Eligible receivables are credit card receivables

  .   that have arisen under an eligible account,

  .   that were created in compliance in all material respects with all
      requirements of law and pursuant to a credit card agreement that
      complies in all material respects with all requirements of law,

  .   with respect to which all material consents, licenses, approvals or
      authorizations of, or registrations with, any governmental authority
      required to be obtained or given in connection with the creation of
      that receivable or the execution, delivery, creation and performance
      by Citibank (South Dakota) or by the original credit card issuer, if
      not Citibank (South Dakota), of the related credit card agreement have
      been duly obtained or given and are in full force and effect,

  .   as to which at the time of their transfer to the master trust, the
      Banks or the master trust have good and marketable title, free and
      clear of all liens, encumbrances, charges and security interests,

  .   that have been the subject of a valid sale and assignment from the
      Banks to the master trust of all the Banks' right, title and interest
      in the receivable or the grant of a first priority perfected security
      interest in the receivable and its proceeds,


                                       94
<PAGE>

  .   that will at all times be a legal, valid and binding payment
      obligation of the cardholder enforceable against the cardholder in
      accordance with its terms, except for certain bankruptcy-related
      matters,

  .   that at the time of their transfer to the master trust, have not been
      waived or modified except as permitted under the pooling and servicing
      agreement,

  .   that are not at the time of their transfer to the master trust subject
      to any right of rescission, set off, counterclaim or defense,
      including the defense of usury, other than certain bankruptcy-related
      defenses,

  .   as to which the Banks have satisfied all obligations to be fulfilled
      at the time it is transferred to the master trust,

  .   as to which the Banks have done nothing, at the time of its transfer
      to the master trust, to impair the rights of the master trust or
      investor certificateholders, and

  .   that constitutes either an "account" or a "general intangible" under
      the Uniform Commercial Code in effect in the states of Nevada and
      South Dakota.

If the Banks breach any of these representations or warranties and the breach
has a material adverse effect on the investor certificateholders' interest, the
receivables in the affected account will be reassigned to the Banks if the
breach remains uncured after a specified cure period. In general, the sellers'
interest will be reduced by the amount of the reassigned receivables. However,
if there is not sufficient sellers' interest to bear the reduction, the Banks
are obligated to contribute funds equal to the amount of the deficiency.

    Each Bank also represents and warrants to the master trust that as of the
issuance date for a series of investor certificates the pooling and servicing
agreement and related series supplement create a valid sale, transfer and
assignment to the master trust of all right, title and interest of that Bank in
the receivables or the grant of a first priority perfected security interest in
those receivables under the Uniform Commercial Code. If the Banks breach this
representation and warranty and the breach has a material adverse effect on the
investor certificateholders' interest, the master trust trustee or the holders
of the investor certificates may direct the Banks to accept the reassignment of
the receivables in the master trust. The reassignment price will generally be
equal to the aggregate invested amount of all series of investor certificates,
including the collateral certificate, issued by the master trust, plus accrued
and unpaid interest on those certificates.

    We cannot assure that all of the credit card accounts designated to the
master trust will continue to meet the eligibility requirements that were
satisfied upon their inclusion in the master trust throughout the life of the
master trust.

The Servicer

    The pooling and servicing agreement designates Citibank (South Dakota) to
service the credit card accounts on behalf of the master trust. The servicer is
required to service the accounts in accordance with customary and usual
procedures for servicing credit card receivables. Its duties include billing,
collecting and recording payments on the receivables,

                                       95
<PAGE>

communicating with cardholders, investigating payment delinquencies on
accounts, maintaining records for each cardholder account and other managerial
and custodial functions.

    The servicer also deposits collections on the receivables into a collection
account maintained for the master trust, calculates amounts from those
collections to be allocated to each series of investor certificates issued by
the master trust and prepares monthly reports.

    If the servicer defaults in the performance of its duties then the servicer
may be terminated and the master trust trustee or a third party meeting the
eligibility requirements specified in the pooling and servicing agreement will
replace the servicer.

    The servicer receives a monthly fee as compensation for its servicing
activities. For each series of master trust investor certificates, including
the collateral certificate, the servicer receives monthly compensation
generally equal to

  .   0.37% per annum of the invested amount of the investor certificates of
      that series so long as Citibank (South Dakota) or an affiliate is the
      servicer, or 0.77% per annum if there is a different servicer,

  .   plus, the investor certificateholders portion of finance charge
      collections that is attributable to interchange up to a maximum amount
      equal to 1.50% per annum of the invested amount of the investor
      certificates of that series.

    The servicer's fee is paid from the finance charge collections allocated to
each series. The servicer is responsible to pay from its servicing compensation
expenses of the master trust, including the fees and expenses of the master
trust trustee and independent accountants.

    For a description of the credit card business conducted by the servicer,
see "The Credit Card Business of Citibank (South Dakota)" attached as Annex I
to this prospectus.

Master Trust Issuances; Sellers' Interest

    The master trust is permitted to issue multiple series of investor
certificates. Each series represents an undivided ownership interest in the
assets of the master trust. The terms of each series are determined at the time
of issuance and are contained in a supplement to the pooling and servicing
agreement.

    The collateral certificate--which is the issuer's primary source of funds
for payments on the notes--is a series of investor certificates.

    The ability of the master trust to issue a new series of investor
certificates is limited by some conditions, including the conditions that the
Banks deliver the required tax opinions, the Banks' remaining interest in the
principal receivables not being reduced to less than 2% of the total amount of
principal in the master trust, and the issuance not cause the rating assigned
to any outstanding series or class of investor certificates by the rating
agencies to be withdrawn or reduced.

                                       96
<PAGE>

    The sellers' interest is the economic interest in the master trust
remaining after subtracting from the aggregate economic interests in the master
trust the interests represented by the collateral certificate and all other
investor certificates issued by the master trust. The sellers' interest is
owned by the Banks.

Allocation of Collections, Losses and Fees

    Cardholder payments received each month are separated into principal
collections and finance charge collections.

    In general, finance charge collections, principal collections, losses and
expenses are allocated to the master trust investor certificates, including the
collateral certificate, and to the sellers' interest as follows:

  .   first, collections of finance charge receivables and collections of
      principal receivables are allocated among the different series of
      certificates issued by the master trust, including the collateral
      certificate, pro rata based on the invested amount of each series; and

  .   second, following the allocation to each series, collections of
      finance charge receivables and principal receivables are further
      allocated between the investors in the series and the sellers'
      interest on a similar basis.

    There is an exception to the pro rata allocations described in the
preceding paragraph. In the master trust, when the principal amount of an
investor certificate other than the collateral certificate begins to amortize,
a special allocation procedure is followed. In this case, collections of
principal receivables continue to be allocated between investors in the series
and the sellers' interest as if the invested amount of the series had not been
reduced by principal collections deposited to a principal funding subaccount or
paid to investors. Allocations of principal collections between the investors
in a series and the sellers' interest is based on the invested amount of the
series "fixed" at the time immediately before the first deposit of principal
collections into a principal funding account or the time immediately before the
first payment of principal collections to investors. Distributions of ongoing
collections of finance charge receivables, as well as losses and expenses,
however, are not allocated on this type of a fixed basis. In the case of the
collateral certificate, each class of notes is treated as a separate series of
investor certificates that becomes "fixed" immediately before the issuer begins
to allocate principal collections to the principal funding subaccount for that
class, whether for budgeted deposits or prefunding, or upon the occurrence of
the expected principal payment date, an early redemption event, event of
default or other optional or mandatory redemption.

    Principal collections that are allocated to any series of master trust
investor certificates, including the collateral certificate, are first used to
pay any principal of those investor certificates, or in the case of the
collateral certificate, the notes, if due, and any excess is then reallocated
to pay principal of any other series of investor certificates that has a
shortfall of principal collections, including the collateral certificate.
Principal collections that are not

                                       97
<PAGE>

needed to pay investor certificates or notes are generally reinvested in newly
generated credit card receivables.

    For the application of finance charge collections and principal collections
that are allocated to the collateral certificate, see "Deposit and Application
of Funds."

Early Amortization Events

    An early payout of principal to master trust investor certificateholders of
a series, including the collateral certificate, will occur under the
circumstances specified in the pooling and servicing agreement. Each condition
is described as an "early amortization event." Early amortization events
include:

  .   the failure of either Bank to (1) make any payment or deposit required
      under the pooling and servicing agreement or the related series
      supplement within five business days after the payment or deposit was
      required to be made or (2) observe or perform any of its other
      covenants or agreements in the pooling and servicing agreement or
      series supplement, and that failure has a material adverse affect on
      investors and continues unremedied for 60 days after notice;

  .   a breach of any representation or warranty made by the Banks in the
      pooling and servicing agreement or related series supplement that
      continues to be incorrect in any material respect for 60 days after
      notice;

  .   the occurrence of some bankruptcy events relating to either Bank,
      referred to as "insolvency events";

  .   the failure by the Banks to make a lump addition of credit card
      receivables to the master trust within five business days after the
      date it was required to be made;

  .   the master trust becomes an "investment company" within the meaning of
      the Investment Company Act of 1940, as amended;

  .   the occurrence of a servicer default by Citibank (South Dakota); and

  .   either of the Banks is unable to transfer credit card receivables to
      the master trust.

    A series of master trust investor certificates may have additional early
amortization events applicable to that series. The collateral certificate does
not have any additional amortization events applicable to it, but your notes
may have early redemption events or events of default that may cause an early
payment of principal of your notes.

    After an early amortization event occurs, principal collections will be
used to make monthly payments of principal to the master trust investor
certificateholders of that series until the earlier of payment of the
outstanding principal amount of the certificates of that series and its legal
maturity date. See "--Optional Termination; Final Payment of Master Trust
Investor Certificates." An early amortization event for the collateral
certificate is also an early redemption event for the notes. See "Covenants,
Events of Default and Early Redemption Events--Early Redemption Events."


                                       98
<PAGE>

    In addition to the consequences of an early amortization event described in
the preceding paragraph, if an insolvency event occurs the Banks will
immediately cease to transfer credit card receivables to the master trust.
After that time, the master trust trustee will sell the credit card receivables
in the master trust in a commercially reasonable manner and on commercially
reasonable terms unless holders of more than 50% of the unpaid principal amount
of investor certificates of each class of each series including the collateral
certificate, the Banks--other than the insolvent Bank--and each other holder,
if any, of an interest in the master trust, give the master trust trustee other
instructions. The proceeds of that sale or liquidation will be applied to
payments on the investor certificates.

Optional Termination; Final Payment of Master Trust Investor Certificates

    The Banks may repurchase the master trust investor certificates of a
series--other than the collateral certificate--if the invested amount of the
certificates of that series is five percent or less of the initial aggregate
principal amount of the investor certificates. The purchase price will be equal
to the invested amount, plus accrued interest.

    If the invested amount of the master trust investor certificates of a
series is greater than zero on its legal maturity date, the master trust
trustee will sell credit cards receivables in an amount, generally, of up to
110% of the invested amount. The net proceeds of the sale will be allocated to
the investor certificates. Sale proceeds allocable to the collateral
certificate will be treated as principal collections and allocated to the
notes. The legal maturity date of the collateral certificate is September 7,
2020, but may be extended from time to time by notice from the issuer to the
master trust, with the consent of the rating agencies that rate the notes and
the delivery of the type of federal tax opinions needed for the issuance of a
new series of notes. See "The Notes--Issuances of New Series, Classes and
Subclasses of Notes."

                                  TAX MATTERS

    This section summarizes the material U.S. federal income tax consequences
to noteholders. However, the discussion is limited in the following ways:

  .   The discussion only covers you if you buy your notes in the initial
      offering.

  .   The discussion only covers you if you hold your notes as a capital
      asset--that is, for investment purposes--and if you do not have a
      special tax status.

  .   The discussion does not cover tax consequences that depend upon your
      particular tax circumstances. You should consult your tax advisor
      about the consequences of holding notes in your particular situation.

  .   The discussion is based on current law. Changes in the law may change
      the tax treatment of the notes.

  .   The discussion does not cover state, local or foreign law.

  .   The discussion does not cover every type of note that the issuer might
      issue. For example, it does not cover notes with an expected principal
      payment date within

                                       99
<PAGE>

      one year of issuance, foreign currency notes, or notes that are not to
      be characterized as debt for federal income tax purposes. If your
      notes are of a type not described in this summary, additional tax
      information will be provided in the applicable supplement to this
      prospectus.

  .   The discussion does not apply to notes issued at more than a small
      discount from their stated principal amount. More precisely, the
      discussion applies only if the discount is less than 1/4% times the
      number of full years from the issue date to the expected principal
      payment date of the notes. This discount is referred to as "de minimis
      OID." If the discount on your notes exceeds this de minimis amount,
      the original issue discount (OID) rules of the Internal Revenue Code
      will apply and additional information will be provided in a supplement
      to this prospectus.

  .   The discussion does not apply to you if you are a non-U.S. noteholder
      and if you (a) own 10% or more of the voting stock of Citigroup Inc.,
      (b) are a "controlled foreign corporation" with respect to Citigroup,
      (c) are related to holders of any equity interest in the issuer other
      than the Banks, (d) are related to any holder of any equity interest
      in the master trust other than the issuer or the Banks or (e) are a
      bank making a loan in the ordinary course of its business.

  .   There is no authority concerning many of the tax issues concerning the
      issuer and the notes. We have not requested a ruling from the Internal
      Revenue Service on the tax consequences of owning the notes. As a
      result, the Internal Revenue Service could disagree with portions of
      this discussion.

    Because of these limitations, and because of the uncertainties described
under "Other Possible Tax Characterizations," we strongly encourage you to
consult your tax advisor before purchasing notes.

Tax Characterization of the Notes

    Cravath, Swaine & Moore, special federal tax counsel to the Banks and the
issuer, referred to in this capacity as "tax counsel," will provide an opinion
to the issuer that the notes are properly characterized as indebtedness for
federal income tax purposes. In addition, noteholders will agree, by acquiring
notes, to treat the notes as debt of the Banks for federal, state and local
income and franchise tax purposes. The Banks agree to treat the notes in the
same manner for these purposes, although they will treat the notes as equity
for some nontax purposes.

Tax Characterization of the Issuer

    Tax counsel will provide an opinion that the issuer will not be an
association--or publicly traded partnership--taxable as a corporation for
federal income tax purposes. As a result, the issuer will not have to pay
federal income tax.

    The precise tax characterization of the issuer for federal income tax
purposes is not certain. It might be viewed as merely holding assets on behalf
of the Banks as collateral for notes issued by the Banks. On the other hand,
the issuer could be viewed as a separate entity

                                      100
<PAGE>

for tax purposes, probably a partnership, issuing its own notes. This
distinction, however, should not have a significant tax effect on noteholders
except as stated below under "Other Possible Tax Characterizations."

U.S. and Non-U.S. Noteholders

    Many of the tax consequences of your owning notes depend upon whether you
are a "U.S. noteholder" or a "non-U.S. noteholder."

    A "U.S. noteholder" is (a) an individual U.S. citizen or resident alien;
(b) a corporation, or entity taxable as a corporation, that was created under
U.S. law, whether federal or state; or (c) an estate or trust that must pay
U.S. federal income tax on its worldwide income.

    A "non-U.S. noteholder" is a person or entity that is not a U.S.
noteholder.

    If a partnership holds notes, the tax treatment of a partner will generally
depend upon the status of the partner and upon the activities of the
partnership. Partners of partnerships holding notes should consult their tax
advisors.

Tax Consequences to U.S. Noteholders

  Interest

    Unless the OID rules apply as described in the next paragraph:

  .   If you are a cash method taxpayer--which includes most individual
      noteholders--you must report interest on the notes in your income when
      you receive it.

  .   If you are an accrual method taxpayer, you must report interest on the
      notes in your income as it accrues.

  Possible OID on the Notes

    Your notes might be treated as having OID, even if they satisfy the
requirement for de minimis OID described above in the seventh bullet point
under "Tax Matters." This result could arise in two ways:

  .   Interest on your notes is not paid in full on a scheduled payment
      date. Your notes might then be treated as having OID from that date
      until their principal is fully paid.

  .   All notes might have OID from their date of issuance, because interest
      is only payable out of specified cash flows allocated to the
      collateral certificate. However, the Banks intend to take the position
      that OID does not arise under this rule.

                                      101
<PAGE>

    If your note has OID, all interest on the note would be taxable in
accordance with the rules for accruing OID. In general, there would not be a
significant adverse effect on you. However:

  .   You would have to report interest income on the note as it accrues
      rather than when it is paid, even if you are on the cash method of
      accounting.

  .   If the note was issued at a small discount from its face amount--that
      is, with de minimis OID--you would have to accrue that discount into
      income over the life of the note.

  Premium and Discount

    Additional special rules apply in the following situations:

  .   If you buy a note in the initial offering for more than its stated
      principal amount, the excess amount you pay will be "bond premium."
      You can use bond premium to reduce your taxable interest income over
      the life of your note.

  .   If you buy a note in the initial offering for less than its initial
      offering price to the public, special rules concerning "market
      discount" may apply.

    Appropriate adjustments to tax basis are made in these situations.
Noteholders in these situations should consult their tax advisors.

  Sale or Retirement of Notes

    On your sale or retirement of your note:

  .   You will have taxable gain or loss equal to the difference between the
      amount received by you and your tax basis in the note.

  .   Your tax basis in your note is your cost, after taking into account
      adjustments for OID, premium and discount.

  .   Your gain or loss will generally be capital gain or loss, and will be
      long-term capital gain or loss if you held your note for more than one
      year.

  .   If your note was issued at a de minimis OID, you must report that
      discount in your income as taxable gain on a proportionate basis as
      you receive principal of the note.

  .   If you sell a note between interest payment dates, a portion of the
      amount you receive reflects interest that has accrued on the note but
      has not yet been paid by the sale date. That amount is treated as
      ordinary interest income and not as sale proceeds.

  Information Reporting and Backup Withholding

    Under the tax rules concerning information reporting to the Internal
Revenue Service:

  .   Assuming you hold your notes through a broker or other securities
      intermediary, the intermediary must provide information to the
      Internal Revenue Service concerning interest, OID and retirement
      proceeds on your notes, unless an exemption applies.


                                      102
<PAGE>

  .   Similarly, unless an exemption applies, you must provide the
      intermediary with your Taxpayer Identification Number for its use in
      reporting information to the Internal Revenue Service. If you are an
      individual, this is your social security number. You are also required
      to comply with other Internal Revenue Service requirements concerning
      information reporting.

  .   If you are required to comply with these requirements but do not
      comply, the intermediary must withhold 31% of all amounts payable to
      you on the notes, including principal payments. This is called "backup
      withholding." If the intermediary withholds payments, you may use the
      withheld amount as a credit against your federal income tax liability.

  .   All individual U.S. noteholders are required to comply with these
      requirements. Some U.S. noteholders, including all corporations, tax-
      exempt organizations and individual retirement accounts, are exempt
      from these requirements.

  Other Possible Tax Characterizations

    Since we are not obtaining a ruling from the Internal Revenue Service on
the tax consequences of the notes, the Internal Revenue Service could disagree
with the intended tax consequences or with the opinions of tax counsel
described above under the headings "Tax Characterization of the Notes" and "Tax
Characterization of the Issuer." As a result:

  .   The notes might be treated as equity interests in a partnership rather
      than debt for tax purposes. Noteholders would then be treated as
      partners in a partnership, with possible adverse tax results. In
      particular, individual noteholders would be required to include income
      of the issuer or the master trust in their own income as it accrues
      rather than when it is paid, and might not be allowed a deduction for
      certain expenses of the issuer or the master trust, resulting in a
      greater amount of taxable income than cash received.

  .   The issuer--and possibly the master trust--might initially or in the
      future be treated as a taxable corporation, with the notes treated as
      debt or equity in the corporation. Tax imposed on the issuer or the
      master trust could significantly reduce the amount of cash otherwise
      available for payment to noteholders.

Tax Consequences to Non-U.S. Noteholders

  Withholding Taxes

    Generally, assuming the notes are debt for federal income tax purposes--as
provided in the opinion of tax counsel--no U.S. taxes are required to be
withheld from payments of principal and interest on the notes.

                                      103
<PAGE>

    However, for the exemption from withholding taxes to apply to you, you must
meet one of the following requirements:

  .   You provide your name, address and a signed statement that you are the
      beneficial owner of the notes and that you are not as a U.S.
      noteholder. This statement is generally made on Internal Revenue
      Service Form W-8BEN.

  .   You or your agent claim an exemption from withholding tax under an
      applicable tax treaty. This claim is generally made on Form W-8BEN.

  .   You or your agent claim an exemption from withholding tax on the
      ground that the income is effectively connected with the conduct of a
      trade or business in the U.S. This claim is generally made on Form W-
      8ECI.

    You should consult your tax advisor about the specific procedures for
satisfying these requirements. These procedures will change on January 1, 2001.
In addition, a claim for exemption will not be valid if the person receiving
the applicable form has actual knowledge that the statements on the form are
false.

  Sale or Retirement of Notes

    If you sell a note or it is redeemed, you will not have to pay federal
income tax on any gain unless one of the following applies:

  .   The gain is connected with a trade or business that you conduct in the
      U.S.

  .   You are an individual, you are present in the U.S. for at least 183
      days during the year in which you dispose of the note, and other
      conditions are satisfied.

  .   The gain represents accrued interest or OID, in which case the rules
      for interest would apply.

  U.S. Trade or Business

    If you hold your note in connection with a trade or business that you are
conducting in the U.S.:

  .   Any interest on the note, and any gain from disposing of the note,
      generally will be taxable as income as if you were a U.S. noteholder.

  .   If you are a corporation, you may be required to pay the "branch
      profits tax" on your earnings that are connected with your U.S. trade
      or business, including earnings from the note. This tax is 30%, but
      may be reduced or eliminated by an applicable income tax treaty.

  Estate Taxes

    If you are an individual, no U.S. estate tax will apply to your note when
you die. However, this rule only applies if, at your death, payments on the
note were not connected to a trade or business that you were conducting in the
U.S.

  Information Reporting and Backup Withholding

    U.S. rules concerning information reporting and backup withholding are
described above under the heading "Tax Consequences to U.S. Noteholders." Under
these rules:

  .   Principal and interest payments you receive will be automatically
      exempt from the usual rules if you provide the tax certifications
      needed to avoid withholding tax on interest, unless the recipient of
      the applicable form knows that the form is false. However, interest
      payments made to you will be reported to the Internal Revenue Service
      on Form 1042-S.

  .   Sale proceeds you receive on a sale of your notes through a broker may
      be subject to these rules if you are not eligible for an exemption. In
      particular, information reporting and backup reporting may apply if
      you use the U.S. office of a broker. Information reporting, but not
      backup withholding, may apply if you use the foreign office of a
      broker that has certain connections to the U.S. You should consult
      your tax advisor concerning information reporting and backup
      withholding on a sale.

  Other Possible Tax Characterizations

    If the issuer or the master trust is treated as a taxable corporation, the
tax liability of the issuer or the master trust could reduce the amount of cash
available to noteholders. In addition, if your notes are characterized as
equity rather than debt for federal income tax purposes, there could be
material adverse tax consequences to you. For example:

  .   If your notes were equity interests in a partnership, (a) 30% U.S.
      withholding tax might apply to the gross amount of income of the
      issuer allocable to you, or (b) you might have to file a tax return in
      the U.S. and pay tax on your share of net income of the issuer as if
      that income were your U.S. business income. A corporate noteholder
      might also be required to pay the "branch profits tax."

  .   If your notes are equity interests in a corporation, all interest
      payable to you might be treated as a dividend subject to 30%
      withholding tax, or a lower rate provided for dividends by a tax
      treaty.

    Non-U.S. noteholders should consult their tax advisors concerning these
risks.

                             BENEFIT PLAN INVESTORS

    Benefit plans are required to comply with restrictions under the Internal
Revenue Code and the Employee Retirement Income Security Act of 1974, known as
ERISA. These restrictions include rules concerning prudence and diversification
of the investment of assets of a benefit plan--referred to as "plan assets." A
benefit plan fiduciary should consider whether an investment by the benefit
plan in notes complies with these requirements.

                                      105
<PAGE>

    In general, a benefit plan for these purposes includes:

  .   an employee benefit plan that is tax-qualified under the Internal
      Revenue Code and provides deferred compensation to employees--such as
      a pension, profit-sharing, section 401(k) or Keogh plan;

  .   an individual retirement account; and

  .   a collective investment fund or other entity, if (a) the fund or
      entity has one or more benefit plan investors and (b) certain "look-
      through" rules apply and treat the assets of the fund or entity as
      constituting plan assets of the benefit plan investor.

    However, a plan maintained by a government is not a benefit plan unless it
is tax-qualified under the Internal Revenue Code. A fund or other entity--
including an insurance company general account--considering an investment in
notes should consult its tax advisors concerning whether its assets might be
considered plan assets under these rules.

Prohibited Transactions

    ERISA and the Internal Revenue Code also prohibit transactions of a
specified type between a benefit plan and a party in interest who is related in
a specified manner to the benefit plan. Violation of these prohibited
transaction rules may result in significant penalties. There are statutory
exemptions from the prohibited transaction rules, and the U.S. Department of
Labor has granted administrative exemptions of specified transactions.

Potential Prohibited Transactions from Investment in Notes

    There are two categories of prohibited transactions that might arise from a
benefit plan's investment in notes. Fiduciaries of benefit plans contemplating
an investment in notes should carefully consider whether the investment would
violate these rules.

  Prohibited transactions between the benefit plan and a party in interest

    The first category of prohibited transaction could arise on the grounds
that the benefit plan, by purchasing notes, was engaged in a prohibited
transaction with a party in interest. A prohibited transaction could arise, for
example, if the notes were viewed as debt of the Banks and a Bank was a party
in interest as to the benefit plan. A prohibited transaction could also arise
if a Bank, the master trust trustee, the indenture trustee, the servicer or
another party with an economic relationship to the issuer or the master trust
either

  .   is involved in the investment decision for the benefit plan to
      purchase notes or

  .   is otherwise a party in interest as to the benefit plan.

                                      106
<PAGE>

    If a prohibited transaction might result from the benefit plan's purchase
of notes, an administrative exemption from the prohibited transaction rules
might be available to permit an investment in notes. The exemptions that are
potentially available include the following prohibited transaction class
exemptions:

  .   96-23, available to "in-house asset managers";

  .   95-60, available to insurance company general accounts;

  .   91-38, available to bank collective investment funds;

  .   90-1, available to insurance company pooled separate accounts; and

  .   84-14, available to "qualified professional asset managers."

    However, even if the benefit plan is eligible for one of these exemptions,
the exemption may not cover every aspect of the investment by the benefit plan
that might be a prohibited transaction.

  Prohibited transactions between the issuer or master trust and a party in
  interest

    The second category of prohibited transactions could arise if

  .   a benefit plan acquires notes, and

  .   under a Department of Labor plan asset regulation, assets of the
      issuer or the master trust are treated as if they were plan assets of
      the benefit plan.

    In this case, every transaction by the issuer or the master trust would be
treated as a transaction by the benefit plan using plan assets.

    If assets of the issuer or the master trust are treated as plan assets, a
prohibited transaction could result if the issuer or the master trust itself
engages in a transaction with a party in interest as to the benefit plan. For
example, if the master trust assets are treated as assets of a benefit plan and
the master trust holds a credit card receivable that is an obligation of a
participant in that same benefit plan, then there would be a prohibited
extension of credit between the benefit plan and a party in interest, the plan
participant.

    As a result, if assets of the issuer or the master trust are treated as
plan assets, there would be a significant risk of a prohibited transaction.
Moreover, the prohibited transaction class exemptions referred to above could
not be relied on to exempt all the transactions of the issuer or the master
trust from the prohibited transaction rules. In addition, because all the
assets of the issuer or the master trust would be treated as plan assets,
managers of those assets might be required to comply with the fiduciary
responsibility rules of ERISA.

    Under an exemption in the plan asset regulations, assets of the issuer or
master trust would not be considered plan assets, and so this risk of
prohibited transactions would not arise, if a benefit plan purchased a note
that

  .   was treated as indebtedness under local law, and

  .   had no "substantial equity features."

                                      107
<PAGE>

    The issuer expects that all notes offered by this prospectus will be
indebtedness under local law. Likewise, although there is no authority directly
on point, the issuer believes that the notes should not be considered to have
substantial equity features. As a result, the plan asset regulations should not
apply to cause assets of the issuer or the master trust to be treated as plan
assets.

Investment by Benefit Plan Investors

    For the reasons described in the preceding sections, benefit plans can
purchase notes. However, the fiduciary of the benefit plan must ultimately
determine whether the requirements of the plan asset regulation are satisfied.
More generally, the fiduciary must determine whether the benefit plan's
investment in notes will result in one or more nonexempt prohibited
transactions or otherwise violate the provisions of ERISA or the Internal
Revenue Code.

Tax Consequences to Benefit Plans

    In general, assuming the notes are debt for federal income tax purposes,
interest income on notes would not be taxable to benefit plans that were tax-
exempt under the Internal Revenue Code, unless the notes were "debt-financed
property" because of borrowings by the benefit plan itself. However, if,
contrary to the opinion of tax counsel, for federal income tax purposes, the
notes were equity interests in a partnership and the partnership or the master
trust were viewed as having other outstanding debt, then all or part of the
interest income on the notes would be taxable to the benefit plan as "debt-
financed income." Benefit plans should consult their tax advisors concerning
the tax consequences of purchasing notes.

                              PLAN OF DISTRIBUTION

    The issuer may offer and sell the notes in any of three ways:

  .   directly to one or more purchasers;

  .   through agents; or

  .   through underwriters.

    Any underwriter or agent that offers the notes may be an affiliate of the
issuer, and offers and sales of notes may include secondary market transactions
by affiliates of the issuer. These affiliates may act as principal or agent in
secondary market transactions. Secondary market transactions will be made at
prices related to prevailing market prices at the time of sale.

    The issuer will specify in a supplement to this prospectus the terms of
each offering, including

  .   the name or names of any underwriters or agents,

  .   the managing underwriters of any underwriting syndicate,


                                      108
<PAGE>

  .   the public offering or purchase price,

  .   the net proceeds to the issuer from the sale,

  .   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

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

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

    The issuer may change any initial public offering price and any discounts
or concessions allowed or reallowed or paid to dealers. If indicated in a
supplement to this prospectus, the issuer will authorize underwriters or agents
to solicit offers by certain institutions to purchase securities from the
issuer pursuant to delayed delivery contracts providing for payment and
delivery at a future date.

    Any underwriter or agent participating in the distribution of securities,
including notes offered by this prospectus, may be deemed to be an underwriter
of those securities under the Securities Act of 1933 and any discounts or
commissions received by them and any profit realized by them on the sale or
resale of the securities may be deemed to be underwriting discounts and
commissions.

    The issuer may agree to indemnify underwriters, agents and their
controlling persons against certain civil liabilities, including liabilities
under the Securities Act of 1933 in connection with their participation in the
distribution of issuer's notes.

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

                           GLOSSARY OF DEFINED TERMS

    "Excess Finance Charge Collections" means finance charge collections that
are allocated to the collateral certificate, and are not needed in the month of
allocation to pay the master trust servicer's fees and expenses, to reimburse
charge-offs of principal receivables in the master trust that are allocated to
the collateral certificate, to pay the indenture trustee's fees and expenses,
or to pay interest on notes.

    "Invested Amount" of any investor certificate issued by the master trust,
including the collateral certificate, is the fluctuating amount representing
the investment of investors, other than the Banks, in the pool of credit card
principal receivables in the master trust. The Invested Amount of the
collateral certificate is equal to

  .   the aggregate outstanding dollar principal amount of the notes;

  .   minus the amount of charge-offs of principal receivables in the master
      trust allocated to the collateral certificate;

  .   minus the amount of reallocations of principal collections on the
      collateral certificate that are applied to pay interest on the notes;

  .   plus the amount of Excess Finance Charge Collections that are
      allocated to the collateral certificate to reimburse earlier charge-
      offs of principal receivables and to reimburse reductions of the
      Invested Amount from reallocations of principal collections to pay
      interest on senior classes of notes; and

  .   minus the aggregate amount on deposit in the principal funding account
      for the outstanding notes.

    The Invested Amount of the collateral certificate will be increased by:

  .   the initial outstanding dollar principal amount of new issuances of
      notes;

  .   accretions of principal on discount notes; and

  .   reimbursement of earlier reductions from Excess Finance Charge
      Collections.

    The Invested Amount of the collateral certificate will be decreased by:

  .   payments of principal collections to the issuer, including both
      principal collections that are allocated to pay principal of the notes
      and those reallocated to pay interest on the notes; and

  .   charge-offs of principal receivables in the master trust that are
      allocated to the collateral certificate.

    The Invested Amount of the collateral certificate will always be equal to
the sum of the nominal liquidation amounts for all series and classes of notes.

    "Monthly Interest Date" means, with respect to any class or subclass of
notes:

  .   for any month in which interest is to be paid, the scheduled interest
      payment date, and

                                      111
<PAGE>

  .   for any month in which no scheduled interest payment date occurs, the
      date in that month corresponding numerically to the next scheduled
      interest payment date for that class or subclass of notes, or in the
      case of a class of zero-coupon discount notes, the expected principal
      payment date for that class; but

     --  if there is no numerically corresponding day in that month, then
         the Monthly Interest Date will be the last business day of the
         month, and

     --  if the numerically corresponding day is not a business day with
         respect to that class or subclass, the Monthly Interest Date will
         be the next following business day, unless that business day would
         fall in the following month, in which case the monthly interest
         date will be the last business day of the earlier month.

    "Monthly Principal Date" means with respect to any class or subclass of
notes:

  .   for any month in which the expected principal payment date occurs, the
      expected principal payment date, or if that day is not a business day,
      the next following business day, and

  .   for any month in which no expected principal payment date occurs, the
      date in that month corresponding numerically to the expected principal
      payment date for that class or subclass of notes; but

     --  if there is no numerically corresponding day in that month, then
         the Monthly Principal Date will be the last business day of the
         month, and

     --  if the numerically corresponding day is not a business day with
         respect to that class or subclass, the Monthly Principal Date will
         be the next following business day, unless that business day would
         fall in the following month, in which case the Monthly Principal
         Date will be the last business day of the earlier month.

    "Performing" means, with respect to any derivative agreement, that no
payment default or repudiation by the derivative counterparty has occurred.

    "Portfolio Yield" of the master trust receivables means, for any month, the
annualized percentage equivalent of a fraction:

  .   the numerator of which is the amount of collections of finance charge
      receivables during the immediately preceding month calculated on a
      cash basis after subtracting the amount of principal receivables that
      were charged off as uncollectible in that monthly period; and

  .   the denominator of which is the total amount of principal receivables
      as of the last day of the immediately preceding month.

    "Required Surplus Finance Charge Amount" means, for any month, an amount
equal to one twelfth of

  .   the Invested Amount of the collateral certificate as of the last day
      of the preceding month, times

                                      112
<PAGE>

  .   a decimal number, which will initially equal zero, but may be changed
      by the issuer so long as the issuer reasonably believes that the
      change will not

     --  adversely affect the amount of funds available for distribution to
         noteholders or the timing of the distribution of those funds,

     --  result in an early redemption event or event of default or

     --  adversely affect the security interest of the indenture trustee in
         the collateral securing the outstanding notes.

    "Surplus Finance Charge Collections" means, for any month, the amount of
finance charge collections allocated to the collateral certificate by the
master trust for that month, minus:

  .   the master trust servicer's fees and expenses for that month;

  .   the indenture trustee's fees and expenses for that month;

  .   the aggregate amount of targeted deposits to be made to the interest
      funding account that month; and

  .   the amount of charge-offs of principal receivables in the master trust
      allocated to the collateral certificate by the master trust for that
      month.

    Solely for purposes of calculating Surplus Finance Charge Collections for
funding the Class C reserve account, the targeted deposit to be made to the
interest funding account for a class of notes that has the benefit of a
derivative agreement will be the greater of the amount payable by the issuer
under that derivative agreement or the amount that would be payable by the
issuer if the derivative were terminated.

    "Threshold Conditions" means:

  .   A rating of "qaAAA" for long-term Class A notes or at least "A-1+/P-1"
      for commercial paper Class A Notes, at least "A" for Class B notes,
      and at least "BBB" for Class C notes, at the time of original issuance
      of the note.

  .   The note to be issued does not have a yield (based on its initial
      yield in the case of a floating rate note) in excess of the yield of
      United States Treasury obligations for a comparable maturity plus 500
      basis points.

  .   The initial dollar principal amount of the class of notes to be issued
      is less than $500 million for Class A notes, $250 million for Class B
      notes, or $250 million for Class C notes.

  .   The expected principal payment date of the note to be issued is no
      more than ten years after the issuance date for Class B and Class C
      notes, or twelve years after the issuance date for Class A notes.

  .   The note to be issued has a single expected principal payment date on
      which all principal of that note is expected to be paid.

  .   The legal maturity date of the note to be issued is no more than two
      years after its expected principal payment date.


                                      113
<PAGE>

  .   Unless the expected principal payment date of the note to be issued is
      within one year of the issuance date, all interest on the note will be
      payable on a current basis at least annually.

  .   If interest on the note to be issued is not at a single fixed rate, it
      is a floating rate, reset at least annually, equal to (i) 100% of a
      single market-based interest index such as LIBOR, the federal funds
      rate, or the prime rate, (ii) plus or minus a single fixed spread, if
      desired, and (iii) subject to a single fixed cap and/or single fixed
      floor, if desired. Interest for the first period may be set at a rate
      approximating the rate that would be set by the formula.

  .   No principal or interest payments on the note to be issued are subject
      to any contingencies, other than in the case of payment of principal,
      availability of funds and subordination.

  .   The issue price of the note to be issued is at least 90% of the
      principal amount, and no more than 102% of the principal amount.

  .   The note to be issued is in registered--not bearer--form.

  .   In the case of a note which has the benefit of a derivative agreement,
      provisions for payments after a derivative agreement default are as
      described in this prospectus, and are not varied by a supplement to
      this prospectus.

  .   At time of the issuance of the note, as to then-outstanding notes or
      master trust investor certificates, (i) there are no outstanding
      rating downgrades of notes or master trust investor certificates, and
      no notes or master trust investor certificates are on credit watch
      with negative implications by a rating agency that rates the
      outstanding notes or master trust investor certificates, (ii) no
      series or class of notes or master trust investor certificates is in
      early amortization or early redemption or default, or will become so
      solely by the passage of time, (iii) no unreimbursed draws have been
      made on any reserve account or cash collateral account for any note or
      master trust investor certificate, and (iv) the issuer and the master
      trust are not in default in payments owed to any third party enhancer
      or derivative counterparty. However, clauses (i), (ii), or (iii) will
      not apply if (a) the event described therein is due solely to the
      credit of a third party enhancer or derivative counterparty and/or the
      failure of that enhancer or counterparty to make payments owed by it
      to the issuer or the master trust, and (b) that derivative
      counterparty or third-party enhancer does not provide a derivative
      agreement or third-party enhancement with respect to the new issuance
      of notes.

  .   The note to be issued has no material terms not described in this
      prospectus, and its subordination features, acceleration provisions
      and remedies are as described in this prospectus, with no variation by
      a supplement to this prospectus.

  .   The note meets any other conditions that may be added from time to
      time by a rating agency then rating the notes.

Any of the foregoing conditions may be eliminated or relaxed with the consent
of the rating agencies then rating the notes.

              This annex forms an integral part of the prospectus.

              THE CREDIT CARD BUSINESS OF CITIBANK (SOUTH DAKOTA)

General

    Citibank (South Dakota) services the credit card accounts at its facilities
in Sioux Falls, South Dakota, and through affiliated credit card processors
pursuant to service contracts.

    Citibank (South Dakota) is a member of MasterCard International and VISA.
MasterCard and VISA credit cards are issued as part of the worldwide MasterCard
International and VISA systems, and transactions creating the receivables
through the use of those credit cards are processed through the MasterCard
International and VISA authorization and settlement systems. If either system
were to materially curtail its activities, or if Citibank (South Dakota) were
to cease being a member of MasterCard International or VISA, for any reason, an
early amortization event with respect to the Collateral Certificate could
occur, and delays in payments on the receivables and possible reductions in the
amounts of receivables could also occur.

    The MasterCard and VISA credit card accounts owned by Citibank (South
Dakota) were principally generated through:

  .   applications mailed directly to prospective cardholders;

  .   applications made available to prospective cardholders at the banking
      facilities of Citibank (South Dakota), at other financial institutions
      and at retail outlets;

  .   applications generated by advertising on television, on radio and in
      magazines;

  .   direct mail and telemarketing solicitation for accounts on a pre-
      approved credit basis;

  .   solicitation of cardholders of existing nonpremium accounts for
      premium accounts;

  .   applications through affinity and co-brand marketing programs; and
      purchases of accounts from other credit card issuers.

    On February 26, 1999 the Banks and some of their affiliates entered into an
agreement with MasterCard International. As a result of this agreement, the
portfolio of credit card accounts owned by Citibank (South Dakota) is expected
to have a larger proportion of MasterCard accounts in the future. This shift
could be accompanied by some attrition of accounts. Based on current analyses,
the Banks do not expect their performance of this agreement or any related
attrition of accounts to have a material adverse effect on investors in the
master trust or the notes.

Acquisition and Use of Credit Cards

    Citibank (South Dakota) reviews each application for a new credit card
account for completeness and creditworthiness. Citibank (South Dakota)
generally obtains a credit report

                                      A-1
<PAGE>

on the applicant issued by an independent credit reporting agency. In the event
there are discrepancies between the application and the credit report Citibank
(South Dakota) may verify the information on the applicant.

    Citibank (South Dakota) generally evaluates the ability of an applicant for
a credit card account to repay credit card balances by applying a credit
scoring system using models developed in-house and models developed with the
assistance of an independent firm with extensive experience in developing
credit scoring models. Credit scoring is intended to provide a general
indication, based on the information available, of the applicant's willingness
and ability to repay his or her obligations. Credit scoring evaluates a
potential cardholder's credit profile to arrive at an estimate of the
associated credit risk. Models for credit scoring are developed by using
statistics to evaluate common characteristics and their correlation with credit
risk. The credit scoring model used to evaluate a particular applicant is based
on a variety of factors, including the manner in which the application was made
or the manner in which the account was acquired as well as the type of
residence of the applicant. From time to time Citibank (South Dakota) reviews
its credit scoring models and, if necessary, updates them to reflect more
current statistical information. Once an application to open an account is
approved an initial credit limit is established for the account based on, among
other things, the applicant's credit score and the source from which the
account was acquired.

    Citibank (South Dakota) also generates new credit card accounts through
direct mail and telemarketing solicitation campaigns directed at individuals
who have been pre-approved by Citibank (South Dakota). Citibank (South Dakota)
identifies potential cardholders for pre-approved direct mail or telemarketing
solicitation campaigns by supplying a list of credit criteria to a credit
bureau which generates a list of individuals who meet those criteria and
forwards the list to a processing vendor. The processing vendor screens the
list in accordance with the credit criteria of Citibank (South Dakota) to
determine the eligibility of the individuals on the list for a pre-approved
solicitation. Individuals qualifying for pre-approved direct mail or
telemarketing solicitation are offered a credit card without having to complete
a detailed application. In the case of pre-approved solicitations, a
predetermined credit limit is reserved for each member of the group being
solicited, which credit limit may be based upon, among other things, each
member's individual credit profile, level of existing and potential
indebtedness relative to assumed income and estimated income and the
availability of additional demographic data for that member.

    In recent years, Citibank (South Dakota) has added affinity and co-brand
marketing to its other means of business development. Affinity marketing
involves the solicitation of prospective cardholders from identifiable groups
with a common interest and/or common cause. Affinity marketing is conducted
through two approaches: the solicitation of organized membership groups with
the written endorsement of the group's leadership, and direct mail solicitation
of prospective cardholders through the use of a list purchased from a group.

    Co-brand marketing is an outgrowth of affinity marketing. It involves the
solicitation of customers of a retailer, service provider or manufacturer which
has a recognizable brand

                                      A-2
<PAGE>

name or logo. Consumers are likely to acquire and use a co-branded card because
of the benefits provided by the co-brander. The co-brander may play a major
role in the marketing and solicitation of co-branded cards. Solicitation
activities used in connection with affinity and co-brand marketing also include
solicitations in appropriate magazines, telemarketing and applications made
available to prospective cardholders in appropriate locations. In some cases,
pre-approved solicitations will be used in the same manner as described in the
second preceding paragraph.

    Citibank (South Dakota) purchases credit card accounts that were originally
opened using criteria established by the institution from which the accounts
were purchased or by the institution from which the selling institution
originally purchased the accounts. Citibank (South Dakota) screens purchased
accounts against criteria established at the time of acquisition to determine
whether any of the purchased accounts should be closed immediately. Any
accounts failing the criteria are closed and no further purchases or cash
advances are authorized. All other purchased accounts remain open. The credit
limits on these accounts are based initially on the limits established or
maintained by the selling institution.

    Each cardholder is party to an agreement governing the terms and conditions
of the account. Each agreement provides that Citibank (South Dakota) may change
or terminate any terms, conditions, services or features of the accounts,
including increasing or decreasing periodic finance charges, other charges or
minimum payments. Credit limits may be adjusted periodically based upon an
evaluation of the cardholder's performance.

Collection of Delinquent Accounts

    Generally, Citibank (South Dakota) considers a MasterCard or VISA credit
card account delinquent if it does not receive the minimum payment due by the
due date indicated on the cardholder's statement. Personnel of Citibank (South
Dakota) and affiliated credit card processors pursuant to service contracts,
supplemented by collection agencies and attorneys retained by Citibank (South
Dakota), attempt to collect delinquent credit card receivables. Under current
practice, Citibank (South Dakota) includes a request for payment of overdue
amounts on all billing statements issued after the account becomes delinquent.

    While collection personnel initiate telephone contact with cardholders
whose credit card accounts are as few as five days delinquent, based on credit
scoring criteria, generally contact is initiated when an account is 35 days or
more delinquent. In the event that initial telephone contact fails to resolve
the delinquency, Citibank (South Dakota) continues to contact the cardholder by
telephone and by mail. Generally, if an account is 15 days delinquent or if a
cardholder exceeds that cardholder's credit limit by more than 5%, no
additional extensions of credit through that account are authorized and, no
more than 95 days after an account becomes delinquent, the account is closed.
The servicer may also, at its discretion, enter into arrangements with
delinquent cardholders to extend or otherwise change payment schedules. The
current policy of the servicer is to charge-off the receivables in an account
when that account becomes 185 days delinquent or, if the servicer receives

                                      A-3
<PAGE>

notice that a cardholder has filed for bankruptcy or has had a bankruptcy
petition filed against it, the servicer will charge-off the receivables in that
account not later than 60 days after the servicer receives notice.

    The credit evaluation, servicing and charge-off policies and collection
practices of Citibank (South Dakota) may change over time in accordance with
the business judgment of Citibank (South Dakota), applicable law and guidelines
established by applicable regulatory authorities.
