Indenture, that a portion of the Series 2000 Invested Amount (corresponding to
the Nominal Liquidation Amount of a series, class or tranche of Notes issued

Trustee shall designate such portion of the Series 2000 Invested Amount as
Excluded Series of the Master Trust. All other portions of the Series 2000
Invested Amount shall not be considered Excluded Series.

     SECTION 8.06. Treatment of Noteholders. For purposes of any provision of
the Agreement or this Series 2000 Supplement requiring or permitting actions
with the consent of, or at the direction of, Investor Certificateholders holding
a specified percentage of the aggregate unpaid principal amount of Investor
Certificates (a) each Noteholder will be deemed to be a Certificateholder; (b)
each Noteholder will be deemed to be the Holder of an aggregate unpaid principal
amount of Series 2000 Certificates equal to the Adjusted Outstanding Dollar
Principal Amount of such Noteholder's Notes; (c) each series of Notes under the
Indenture will be deemed to be a separate Series of Investor Certificates and
the Holder of a Note of such series will be deemed to be the Holder of an
aggregate unpaid principal amount of such Series of Investor Certificates equal
to the Adjusted Outstanding Dollar Principal Amount of such Noteholder's Notes
of such series; (d) each class of Notes of a Single Issuance Series and each

other holder of a Sellers' Certificate or any Affiliate thereof will be deemed

protected in relying upon any such consent or direction, only Notes which the
Trustee knows to be so owned shall be so disregarded. Notes so owned which have
been pledged in good faith shall not be disregarded and may be regarded as
outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Notes and that the pledgee is not
either Seller, the Servicer, any other holder of a Sellers' Certificate or any
Affiliate thereof.

     SECTION 8.07. Sale for Accounting Purposes. The parties hereto intend to

                                  SERIES 2000
                     CREDIT CARD PARTICIPATION CERTIFICATE

                        Summary of Terms and Conditions

     The Receivables consist of Principal Receivables which arise generally from
the purchase of merchandise and services and amounts advanced to cardholders as
cash advances and Finance Charge Receivables which arise generally from Periodic
Rate Finance Charges, Cash Advance Fees, Late Payment Fees and annual membership
fees with respect to the Accounts. This Series 2000 Certificate is one of a
series of Certificates entitled Citibank Credit Card Master Trust I, Series 2000
Credit Card Participation Certificates (the "Series 2000 Certificates"), each of
which represents a fractional undivided interest in certain assets of the Trust.
The Trust Assets are allocated in part to the Certificateholders of all
outstanding Series (the "Certificateholders' Interest") with the remainder
allocated to the Sellers. The aggregate interest represented by the Series 2000
Certificates at any time in the Principal Receivables in the Trust shall not
exceed an amount equal to the Series 2000 Invested Amount at such time. The
Series 2000 Invested Amount on any date will be as computed in accordance with
the Series Supplement. A Sellers' Certificate has been issued to the Sellers
pursuant to the Agreement which represents the Sellers' Interest.

     Subject to the terms and conditions of the Agreement, the Sellers may from
time to time direct the Trustee, on behalf of the Trust, to issue one or more
new Series of Investor Certificates, which will represent fractional undivided
interests in certain of the Trust Assets.

     For each Due Period, the Paying Agent shall distribute to each Series 2000
Certificateholder of record on the last day of the calendar month preceding the
month in which such distribution occurs (each a "Record Date") such Series 2000
Certificateholder's pro rata share of such amounts as are payable to the Series
2000 Certificateholders pursuant to the Agreement and the Series Supplement.
Distributions with respect to this Series 2000 Certificate will be made by the
Paying Agent by check mailed to the address of the Series 2000 Certificateholder
of record appearing in the Certificate Register (or, pursuant to Section 6.01 of
the Series Supplement, to the extent specified by the Series 2000 Certificate
Representative in a written notice to the Trustee and the Servicer, by wire
transfer in accordance with such notice) without the presentation or surrender
of this Series 2000 Certificate or the making of any notation thereon (except
for the final distribution in respect of this Series 2000 Certificate). Final
payment of this Series 2000 Certificate will be made only upon presentation and
surrender of this Series 2000 Certificate at the office or agency specified in
the notice of final distribution delivered by the Trustee to the Series 2000
Certificateholders in accordance with the Agreement and the Series Supplement.

     This Series 2000 Certificate does not represent an obligation of, or an
interest in, the Sellers, the Servicer, any Additional Sellers or any affiliate
of any of them and is not insured or

                                       5

governmental agency or instrumentality. This Series 2000 Certificate is limited
in right of payment to certain Collections with respect to the Receivables (and
certain other amounts), all as more specifically set forth hereinabove and in
the Agreement and the Series Supplement.

     The Agreement or any Supplement may, subject to certain conditions, be
amended by the Sellers, the Servicer and the Trustee without Investor
Certificateholder consent. The Trustee may, but shall not be obligated to, enter
into any such amendment which affects the Trustee's rights, duties or immunities
under the Agreement or otherwise.

     The Agreement or any Supplement may also be amended from time to time
(including in connection with the issuance of a Supplemental Certificate) by the
Servicer, the Sellers and the Trustee, with the consent of the Holders of
Investor Certificates evidencing not less than 66-2/3% of the aggregate unpaid
principal amount of the Investor Certificates of all adversely affected Series,
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Agreement or any Supplement or of
modifying in any manner the rights of the Investor Certificateholders; provided,
however, that no such amendment shall (i) reduce in any manner the amount of or
delay the timing of any distributions to be made to Investor Certificateholders
or deposits of amounts to be so distributed without the consent of each affected
Investor Certificateholder, (ii) change the definition of or the manner of
calculating the interest of any Investor Certificateholder without the consent
of each affected Investor Certificateholder, (iii) reduce the aforesaid
percentage required to consent to any such amendment without the consent of each
Investor Certificateholder or (iv) adversely affect the rating of any Series or
Class by the Rating Agency without the consent of the Holders of Investor
Certificates of such Series or Class evidencing not less than 66-2/3% of the
aggregate unpaid principal amount of the Investor Certificates of such Series or
Class. The Trustee may, but shall not be obligated to, enter into any such
amendment which affects the Trustee's rights, duties or immunities under this
Agreement or otherwise.

     Subject to the limitations set forth in the Agreement and the Series
Supplement, the transfer of this Series 2000 Certificate shall be registered in
the Certificate Register upon surrender of this Series 2000 Certificate for
registration of transfer at any office or agency maintained by the Transfer
Agent and Registrar accompanied by a written instrument of transfer, in a form
satisfactory to the Trustee or the Transfer Agent and Registrar, duly executed
by the Series 2000 Certificateholder or such Series 2000 Certificateholder's
attorney, and duly authorized in writing with such signature guaranteed, and
thereupon one or more new Series 2000 Certificates of authorized denominations
and for the same aggregate fractional undivided interest will be issued to the
designated transferee or transferees.

     As provided in the Agreement and subject to certain limitations therein set
forth, Series 2000 Certificates are exchangeable for new Series 2000
Certificates evidencing like aggregate fractional undivided interests as
requested by the Series 2000 Certificateholder surrendering such Series 2000
Certificates. No service charge may be imposed for any such exchange but the
Servicer or Transfer Agent and Registrar may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith.
