(1) Approximate.

(2)  Determined as described herein under "SUMMARY OF PROSPECTUS AND PROSPECTUS
     SUPPLEMENT--Last Scheduled Distribution Date."

(3)  The Class A-4 and Class A-5 CitiCertificates will each be comprised of two
     components. The Class A-4 CitiCertificate (Component 1) has a Component
     Stated Amount of $9,700,000 and the Class A-4 CitiCertificate (Component 2)
     has a Component Stated Amount of $10,500,000. The Class A-5 CitiCertificate
     (Component 1) has a Component Stated Amount of $9,700,000 and the Class A-5
     CitiCertificate (Component 2) has a Component Stated Amount of $10,500,000.
     The Components of the Class A-4 and Class A-5 CitiCertificates are not
     separately transferable.

(4)  The Class A-7 CitiCertificates are principal-only certificates and will not
     bear interest. 

(5)  The Class A-12 Notional Amount on any Distribution Date will be equal to
     the Stated Amount of the Class A-11 CitiCertificates as of such date. 

(6)  The Class A-14 CitiCertificates are principal-only certificates and will
     not bear interest.

                                   ----------

     The Senior CitiCertificates are being offered by Lehman Brothers Inc. (the
"Senior Underwriter"), and the Offered Subordinated CitiCertificates are being
offered by Salomon Brothers Inc (the "Subordinated Underwriter", and together
with the Senior Underwriter, the "Underwriters" and each, an "Underwriter") from
time to time in negotiated transactions or otherwise at varying prices to be
determined at the time of sale. The Class A-11 CitiCertificates will also be
offered by Edward D. Jones & Co., L.P. (the "Dealer") from time to time in
negotiated transactions or otherwise at varying prices to be determined at the
time of sale. The aggregate proceeds to the Issuer from the sale of the Offered
CitiCertificates will be approximately 98.68093% of the aggregate Initial Stated
Amount of the Class A CitiCertificates, approximately 98.69581% of the aggregate
Initial Stated Amount of the Class M CitiCertificates and approximately
97.05616% of the aggregate Initial Stated Amount of the Offered Class B
CitiCertificates, plus accrued interest (other than on the Initial Stated Amount
of the Class A-7 and Class A-14 CitiCertificates) from July 1, 1998 (the
"Cut-Off Date") to but not including the Closing Date at the rate of 6.50% per
annum thereon and before deduction of expenses payable by the Issuer, subject to
a limited adjustment with respect to the Class A CitiCertificates depending on
the aggregate Initial Stated Amount of the Class A CitiCertificates on the
Closing Date. See "PLAN OF DISTRIBUTION" herein.

     The Offered CitiCertificates are offered subject to receipt and acceptance
by the Underwriters, to prior sale and to the Underwriters' right to reject any
order in whole or in part. It is expected that on or about July 29, 1998,
delivery will be made through the facilities of The Depository Trust Company
("DTC") in the case of the Book-Entry CitiCertificates, and in definitive, fully
registered form, in the case of the Class A-14 CitiCertificates, the Class M
CitiCertificates and the Offered Class B CitiCertificates.

CitiCertificates") in an approximate aggregate Initial Stated Amount of
$290,561,770, subject to a permitted upward or downward variance of up to 5.0%,
one senior subordinated class of REMIC Pass-Through Certificates (the "Class M
CitiCertificates") in an approximate Initial Stated Amount of $6,069,000,
subject to a permitted variance based on final credit enhancement levels, one
subordinated class of REMIC Pass-Through Certificates (the "Class B
CitiCertificates") in an approximate aggregate Initial Stated Amount of
$6,828,697, subject to a permitted variance based on final credit enhancement
levels, one senior class of interest only REMIC Pass-Through Certificates not
offered hereby (the "Unoffered Class A-IO CitiCertificates") in an approximate
initial notional amount of $302,884,997.89, and two classes of residual
interests (the "Residual Certificates"), representing interests in a trust (the
"Trust") to be created by Citicorp Mortgage Securities, Inc. (the "Issuer" or
"CMSI") on or about July 29, 1998. Elections will be made to treat two
segregated asset pools within the Trust as real estate mortgage investment
conduits (each, a "REMIC" or, in the alternative, the "Lower-Tier REMIC" and the
"Upper-Tier REMIC") for federal income tax purposes. The Class A, Unoffered
Class A-IO, Class M and Class B CitiCertificates are collectively referred to as
the "CitiCertificates." The Class A CitiCertificates will consist of Class A-1,
Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8,
Class A-9, Class A-10, Class A-11, Class A-12, Class A-13, and Class A-14
CitiCertificates (each, a "Class A Subclass"). The Class A-1 and Class A-2
CitiCertificates are planned amortization class certificates and are sometimes
referred to as the "PAC Certificates." The Class A-3 CitiCertificates are
targeted amortization class certificates and are sometimes referred to as the
"TAC Certificates." In addition, the Class A-4 and Class A-5 CitiCertificates
will each be comprised of two components. The beneficial owner of a Class A-4 or
Class A-5 CitiCertificate will not have a severable interest in any Component
but will have an undivided interest in the respective Class A Subclass. The
Class A-4 CitiCertificate (Component 1) and Class A-5 CitiCertificate (Component
1) are targeted amortization class Components and are sometimes referred to as
the "TAC Components." The Class A-11 CitiCertificates are also referred to as
the "Retail CitiCertificates." The Class A-12 CitiCertificates are interest-only
CitiCertificates and, accordingly, have no Stated Amount. The Class A-6
CitiCertificates are sometimes referred to as the "Companion Class." The Class
A-7 and Class A-14 CitiCertificates are principal-only certificates and will not
bear interest. The Class B CitiCertificates will consist of Class B-1, Class
B-2, Class B-3, Class B-4 and Class B-5 CitiCertificates (each, a "Class B
Subclass"). The Class B-1 and Class B-2 CitiCertificates (each, an "Offered
Class B Subclass") are referred to herein as the "Offered Class B
CitiCertificates" and the Class B-3, Class B-4 and Class B-5 CitiCertificates
are herein referred to as the "Unoffered Class B CitiCertificates." The Class A
CitiCertificates will initially evidence an undivided beneficial ownership
interest in the property of the Trust ranging from 94.75% to 96.75%, the Class M
CitiCertificates will initially evidence an undivided beneficial ownership
interest in the property of the Trust ranging from 1.00% to 3.00%, and the
Offered Class B CitiCertificates will initially evidence an undivided interest
in the property of the Trust ranging from 0.90% to 1.90% and the Unoffered Class
B CitiCertificates will evidence the remaining undivided interest therein. Only
the Class A CitiCertificates, the Class M CitiCertificates and the Offered Class
B CitiCertificates (the "Offered CitiCertificates") are offered hereby. The
Class A CitiCertificates are sometimes referred to as the "Offered Senior
CitiCertificates," and the Class M CitiCertificates and the Offered Class B
CitiCertificates are sometimes referred to collectively as the "Offered
Subordinated CitiCertificates."

     The Trust Property (the "Pool") will consist primarily of a pool of 20- to
30-year fixed-rate conventional one- to four-family mortgage loans (the
"Mortgage Loans") originated or acquired by Citicorp Mortgage, Inc. ("CMI") with
an aggregate Adjusted Balance as of the Cut-Off Date (the "Initial Mortgage Loan
Balance") equal to approximately $303,459,467, subject to a permitted upward or
downward variance of up to 5.0%, and certain related property, as described
herein. Mortgage Loans acquired by CMI include Mortgage Loans originated or
acquired by Citibank, Federal Savings Bank ("CFSB") or originated by Citibank,
N.A. ("Citibank"). Payments on the Mortgage Loans will be distributed on the
CitiCertificates in accordance with the priorities stated in the "SUMMARY OF
PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions" and
"`DESCRIPTION OF THE OFFERED CITICERTIFICATES."

     Interest on each interest-bearing Offered CitiCertificate will be
distributed on the 25th day of each month (or, if such day is not a business
day, on the next succeeding business day), commencing (except for the Class A-6
CitiCertificates) in August 1998 (each, a "Distribution Date"). The Class A-11
CitiCertificates (the "Retail CitiCertificates") are entitled to the benefit of
a reserve fund (the "Reserve Fund") as protection against Non-Supported Interest
Shortfalls, up to $7,000, the amount of the initial deposit into such Reserve
Fund. The Class A-11 CitiCertificates will also be entitled to the benefit of an
irrevocable certificate guaranty insurance policy (the "Insurance Policy") to be
issued by MBIA Insurance Corporation (the "Insurer") pursuant to which the
Insurer will unconditionally and irrevocably guarantee the current payment of
interest, other than Non-Supported Interest Shortfalls that are covered by the
Reserve Fund, and the payment of any losses of principal allocated to the Class
A-11 CitiCertificates. See "THE INSURANCE POLICY AND THE INSURER" herein. Once
the Reserve Fund has been reduced to zero, Non-Supported Interest Shortfalls
allocated to the Class A-11 CitiCertificates will be covered by the Insurance
Policy. The Class A-6 CitiCertificates are Accrual CitiCertificates. The Class
A-3, Class A-4 and Class A-5 CitiCertificates are sometimes referred to as the
"Accretion Directed CitiCertificates." Distributions of interest on the Class
A-6 CitiCertificates will commence on the date (the "Accretion Termination
Date") that is the earlier to occur of (i) the Distribution Date on which the
Stated Amounts of the

                                      S-2
<PAGE>


(Continued from previous page)

Class A-3, Class A-4 and Class A-5 CitiCertificates have been reduced to zero
and (ii) the Subordination Depletion Date. Prior to any commencement of interest
distributions on the Class A-6 CitiCertificates, interest will accrue thereon
and the amounts soaccrued and available for distribution will be added to the
Stated Amount thereof on the applicable Distribution Date and will be
distributed in reduction of the Stated Amount of the Accretion Directed
CitiCertificates as described under "DESCRIPTION OF THE OFFERED CITICERTIFICATES
- --Distributions in Reduction of Stated Amount of the Offered CitiCertificates"
in this Prospectus Supplement. Interest will accrue on the interest-bearing
Offered CitiCertificates for the periods and at the rates as described herein.
The rights of holders of the Class M CitiCertificates to receive distributions
of interest will be subordinated to the rights of holders of the Class A and
Unoffered Class A-IO CitiCertificates to receive distributions to the extent
described herein. The rights of holders of the Offered Class B CitiCertificates
to receive distributions of interest will be subordinated to the rights of
holders of the Class A, Unoffered Class A-IO and Class M CitiCertificates to
receive distributions to the extent described herein. The rights of holders of
the Unoffered Class B CitiCertificates to receive distributions of interest will
be subordinated to the rights of holders of the Offered CitiCertificates and the
Unoffered Class A-IO CitiCertificates to receive distributions to the extent
described herein.

     On each Distribution Date, distributions in reduction of Stated Amount of
the Class A CitiCertificates, in an amount equal to the Class A Principal
Distribution Amount, will be allocated among the Class A Subclasses then
entitled to receive such distributions in accordance with the priorities set
forth herein. On each Distribution Date, distributions in reduction of Stated
Amount of the Class M CitiCertificates will be made only after the Class A and
Unoffered Class A-IO CitiCertificates have received all distributions to which
they are entitled and the Class M CitiCertificates have received the amount of
interest due them with respect to such Distribution Date. On each Distribution
Date, distributions in reduction of Stated Amount of the Class B-1
CitiCertificates will be made only after the Class A, Unoffered Class A-IO and
Class M CitiCertificates have received all distributions to which they are
entitled and the Class B-1 CitiCertificates have received the amount of interest
due them with respect to such Distribution Date. On each Distribution Date,
distributions in reduction of Stated Amount of the Class B-2 CitiCertificates
will be made only after the Class A, Unoffered Class A-IO, Class M and Class B-1
CitiCertificates have received all distributions to which they are entitled and
the Class B-2 CitiCertificates have received the amount of interest due them
with respect to such Distribution Date. The rights of holders of the Unoffered
Class B CitiCertificates to receive distributions in reduction of Stated Amount
will be subordinated to the rights of holders of the Offered CitiCertificates
and Unoffered Class A-IO CitiCertificates to receive distributions to the extent
described herein.

     THE YIELD TO INVESTORS IN THE OFFERED CITICERTIFICATES WILL BE SENSITIVE IN
VARYING DEGREES TO THE RATE OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) ON THE
MORTGAGE LOANS, WHICH GENERALLY CAN BE PREPAID AT ANY TIME, GENERALLY WITHOUT
PENALTY. THE YIELD TO INVESTORS IN THE OFFERED CITICERTIFICATES WILL BE
ADVERSELY AFFECTED BY ANY SHORTFALLS IN INTEREST COLLECTED ON THE MORTGAGE LOANS
DUE TO PREPAYMENTS OR LIQUIDATIONS. SUCH SHORTFALLS IN INTEREST COLLECTED WILL
BE OFFSET TO THE EXTENT DESCRIBED HEREIN. IN ADDITION, THE YIELD TO MATURITY ON
THE OFFERED CITICERTIFICATES MAY VARY DEPENDING ON THE EXTENT TO WHICH SUCH
CITICERTIFICATES ARE PURCHASED AT A DISCOUNT OR PREMIUM. HOLDERS OF OFFERED
CITICERTIFICATES SHOULD CONSIDER, IN THE CASE OF ANY OFFERED CITICERTIFICATE
PURCHASED AT A DISCOUNT, ESPECIALLY THE CLASS A-7 AND CLASS A-14
CITICERTIFICATES, THE RISK THAT A SLOWER THAN ANTICIPATED RATE OF PRINCIPAL
PAYMENTS WOULD RESULT IN AN ACTUAL YIELD THAT IS LOWER THAN THE ANTICIPATED
YIELD AND, IN THE CASE OF ANY OFFERED CITICERTIFICATE PURCHASED AT A PREMIUM AND
THE CLASS A-12 CITICERTIFICATES, WHICH HAVE NO STATED AMOUNT, THE RISK THAT A
FASTER THAN ANTICIPATED RATE OF PRINCIPAL PAYMENTS WOULD RESULT IN AN ACTUAL
YIELD THAT IS LOWER THAN ANTICIPATED. IN ADDITION, BECAUSE THE CLASS A-3, CLASS
A-4, CLASS A-5, CLASS A-6 AND CLASS A-7 CITICERTIFICATES SUPPORT THE PAC
CERTIFICATES, THE WEIGHTED AVERAGE LIVES OF SUCH CLASS A SUBCLASSES WILL BE
HIGHLY SENSITIVE TO THE RATE OF PREPAYMENTS OF THE MORTGAGE LOANS. BECAUSE
AMOUNTS PAYABLE ON THE CLASS A-14 CITICERTIFICATES DERIVE SOLELY FROM PRINCIPAL
PAYMENTS ON THE MORTGAGE LOANS WITH NET MORTGAGE RATES BELOW 6.50% PER ANNUM,
THE YIELD ON THE CLASS A-14 CITICERTIFICATES WILL BE ADVERSELY AFFECTED BY
SLOWER THAN ANTICIPATED PRINCIPAL PAYMENTS ON SUCH MORTGAGE LOANS. NO
REPRESENTATION IS MADE AS TO THE ANTICIPATED RATE OF PREPAYMENT ON THE MORTGAGE
LOANS OR AS TO THE ANTICIPATED YIELD TO MATURITY OF ANY OFFERED
CITICERTIFICATES.

     Distributions in respect of the Stated Amount of the Class A-11
CitiCertificates are subject to the procedures regarding requests for
distribution and random lot distributions described herein under "DESCRIPTION OF
THE OFFERED CITICERTI-FICATES--Distributions in Reduction of Stated Amount of
the Retail CitiCertificates." The allocation of principal distributions in
respect of any particular Class A-11 CitiCertificate may result in a yield to
maturity that varies significantly from the anticipated yield, and such yields
will vary among holders of Class A-11 CitiCertificates.

     The Retail CitiCertificates may not be an appropriate investment for all
prospective investors. The Retail CitiCertificates would not be an appropriate
investment for an investor requiring a distribution of a particular amount in
reduction of Stated Amount on a specific date or an otherwise predictable stream
of distributions. In addition, although the Senior Underwriter intends to make a
secondary market in Retail CitiCertificates, it has no obligation to do so, and
any such market-making may be discontinued at any time. Finally, there can be no
assurance that an investor will be able to sell a Retail CitiCertificate at a
price which is equal to or greater than the price at which such investor
purchased such CitiCertificate or at a price which fully reflects the fair
market value of the underlying Mortgage Loans.

     The holders of the Class A-13 CitiCertificates will not be entitled to
receive any distributions in reduction of the Stated Amount prior to the
Distribution Date in August 2003, and prior to the Distribution Date in August
2007 will receive a disproportionately small portion of principal prepayments
and other unscheduled recoveries on the Mortgage Loans, unless the Stated
Amounts of all other Class A Subclasses (other than the Class A-14
CitiCertificates) have been reduced to zero or the Stated Amounts of the
Subordinated CitiCertificates have been reduced to zero. As a result, the
weighted average life will be longer, and could be significantly longer, than
would be the case if the Class A-13 CitiCertificates received their pro rata
share of the Class A Percentage and Class A Prepayment Percentage of the Non-PO
Percentage of all principal payments received on the Mortgage Loans.

     The Unoffered Class A-IO CitiCertificates (not offered hereby) are
interest-only CitiCertificates and have no Stated Amount. The Unoffered Class
A-IO CitiCertificates will receive distributions of accrued interest pro rata
together with the interest-bearing Class A CitiCertificates and are not
subordinated to the Class A, Class M or Class B CitiCertificates.

     The Offered CitiCertificates may not be an appropriate investment for all
prospective investors. The Offered CitiCertificates, and in particular the
Retail CitiCertificates, would not be an appropriate investment for an investor
requiring a distribution of a particular amount in reduction of Stated Amount on
a specific date or an otherwise predictable stream of distributions. In
addition, there is currently no secondary market for the Offered
CitiCertificates. Each Underwriter anticipates making a secondary market in the
Offered CitiCertificates purchased by it but is not obligated to do so. There
can be no assurance that such a market will develop or, if it does develop, that
it will provide holders of the Offered CitiCertificates with liquidity of
investment or will continue for the life of the Offered CitiCertificates. There
can be no assurance that the investor will be able to sell an Offered
CitiCertificate at a price which is equal to or greater than the price at which
such investor purchased such Offered CitiCertificate or at a price which fully
reflects the fair market value of the underlying Mortgage Loans.

     The yield to maturity on the Offered Class B CitiCertificates will be more
sensitive to losses due to liquidations of the Mortgage Loans (and the timing
thereof) than the Class A, Unoffered Class A-IO and Class M CitiCertificates, in
the event that the Stated Amount of the Unoffered Class B CitiCertificates has
been reduced to zero. The yield to maturity on the Class M CitiCertificates will
be more sensitive to losses due to liquidations of the Mortgage Loans (and the
timing thereof) than the Class A and Unoffered Class A-IO CitiCertificates, in
the event that the Stated Amount of the Class B CitiCertificates has been
reduced to zero. See "DESCRIPTION OF THE OFFERED CITICERTIFICATES--Prepayment
and Yield Considerations" and "--Yield Considerations With Respect to the
Offered Class B CitiCertificates" in this Prospectus Supplement. Investors
should fully consider the risks associated with an investment in the Class M and
Offered Class B CitiCertificates, including the possibility that such investors
may not fully recover their initial investment as a result of such losses on the
Mortgage Loans.

     The Class M CitiCertificates and the Offered Class B CitiCertificates may
not be transferred unless the transferee has delivered (i) a representation
letter to the Issuer and the Trustee stating either (a) that the transferee is
not a Plan and is not acting on behalf of a Plan or using the assets of a Plan
to effect such purchase or (b) subject to certain conditions described herein,
that the source of funds used to purchase the Class M or Offered Class B
CitiCertificates is an "insurance company general account" or (ii) an opinion of
counsel and other documentation as provided herein. See "RISK FACTORS FOR
PURCHASERS OF CLASS M CITICERTIFICATES AND OFFERED CLASS B
CITICERTIFICATES--Restrictions on Transfer" and "ERISA Considerations" herein.

     The closing of the sale of the Offered CitiCertificates is conditioned upon
the closing of the sale of the Unoffered Class B CitiCertificates. Salomon
Brothers Inc is committed to purchase all of the Unoffered Class B
CitiCertificates if any Offered CitiCertificates are purchased.

     The Offered Senior CitiCertificates (other than the Class A-14
CitiCertificates) will be issued in book-entry form only(the "Book-Entry
CitiCertificates"), and purchasers thereof will not be entitled to receive
definitive certificates except in the limited circumstances set forth herein.
The Book-Entry CitiCertificates will be registered in the name of Cede & Co.
("Cede"),as nominee of DTC, which will be the "holder" or "Certificateholder" of
such Book-Entry CitiCertificates, as such terms are used herein. See
"DESCRIPTION OF THE OFFERED CITICERTIFICATES--Book-Entry Registration" and

     IN CONNECTION WITH THIS OFFERING, EACH UNDERWRITER MAY OVER-ALLOT OR EFFECT

CITICERTIFICATES AT A LEVEL ABOVE THAT WHICH MIGHT OTHERWISE PREVAIL IN THE OPEN

                              Class M and Class B-1 CitiCertificates to the

                            Each Class A and Class M CitiCertificate will
                              qualify at issuance as a "mortgage related
                              security" within the meaning of the Secondary

                              CitiCertificate and for certain other purposes,
                              such notional amount will not entitle a holder to
                              any distributions of principal. The Initial

                              holder of such CitiCertificate is entitled (in
                              addition to distributions of interest, except in
                              the case of the Class A-7 and Class A-14
                              CitiCertificates, which are principal-only
                              certificates, and, in the case of the Class A-6

                              added to the Stated Amount thereof) from the cash
                              flow on the assets in the Pool. 

                            The aggregate of the Stated Amounts of the Class A
                              Subclasses as of any Distribution Date is referred
                              to as the "Class A Stated Amount." The "Class A

                              will equal the Initial Stated Amount thereof
                              (plus, in the case of the Class A-6
                              CitiCertificates, any amounts subsequently added
                              to the Stated Amount thereof) less certain

                              herein. The Stated Amount of the Class A-4 and
                              Class A-5 CitiCertificates is equal to the sum of
                              the Component Stated Amounts of their respective

                              A and Unoffered Class A-IO CitiCertificates to

                              rights of holders of the Offered CitiCertificates
                              and Unoffered Class A-IO CitiCertificates to

                              herein. This subordination provides a certain
                              amount of protection to holders of the Class A and
                              Unoffered Class A-IO CitiCertificates (to the
                              extent of the subordination of the Class M and
                              Class B CitiCertificates), to holders of the Class
                              M CitiCertificates (to the extent of the
                              subordination of the Class B CitiCertificates) and
                              to holders of the Offered Class B CitiCertificates
                              (to the extent of the subordination of the
                              Unoffered Class B CitiCertificates) against delays
                              in the receipt of scheduled payments of interest
                              and principal and against losses associated with
                              the liquidation of defaulted Mortgage Loans and
                              certain losses resulting from the bankruptcy of a
                              Mortgagor. The Class M and Class B
                              CitiCertificates are sometimes referred to
                              collectively as the "Subordinated
                              CitiCertificates." 

                            In addition, in order to increase the period during
                              which the principal balance of the Class M and
                              Class B CitiCertificates remains available as
                              credit enhancement to the Class A
                              CitiCertificates, a disproportionate amount of
                              prepayments and certain unscheduled recoveries
                              with respect to the Mortgage Loans will be
                              allocated to the Class A CitiCertificates (other

                              allocation has the effect of accelerating the
                              amortization of the Class A CitiCertificates
                              while, in the absence of Realized Losses,

                            The Class A-11 CitiCertificates will be entitled to

                              Shortfalls up to the amount of the initial deposit
                              into the Reserve Fund and to the benefit of the

                              Reserve Fund has been exhausted, and losses of

                              including Realized Losses that are (i)
                              attributable to Special Hazards not insured
                              against under a standard hazard insurance policy,

                              in connection with a Mortgage Loan, including a
                              reduction by a bankruptcy court of the principal
                              balance of or the interest rate on a Mortgage Loan
                              or an extension of its maturity, up to the
                              respective limits described below, will not be
                              allocated to the Class A Subclasses until the date
                              on which the Stated Amount of the Class M and
                              Class B CitiCertificates has been reduced to zero
                              (the "Subordination Depletion Date"). Upon the

                              Percentage of such Realized Losses will be
                              allocated pro rata among the Class A

                              Stated Amounts (or, in the case of the Class A-6
                              CitiCertificates, their Initial Stated Amount, if
                              lower) in each case for so long as they are
                              outstanding. Any such Realized Losses allocated to
                              the Class A-11 CitiCertificates will be covered by
                              the Insurance Policy. 

                            Prior to the Subordination Depletion Date, the
                              applicable Non-PO Percentage of such Realized
                              Losses will be allocated first to the Class B
                              Subclasses in reverse numerical order until the
                              Stated Amount of each such Class B Subclass has
                              been reduced to zero, and then to the Class M
                              CitiCertificates until the Stated Amount thereof
                              has been reduced to zero. The applicable PO
                              Percentage of Realized Losses will be allocated to
                              the Class A-14 CitiCertificates as a PO Loss
                              Amount but such loss allocation will give rise to
                              the right to receive, in respect of the Class A-14
                              CitiCertificates, reimbursement of losses so
                              allocated out of certain funds otherwise
                              distributable on the Class M and Class B
                              CitiCertificates. As a result, any such PO Loss
                              Amounts will ultimately be borne by the Class B
                              Subclasses, in reverse numerical order, and then
                              by the Class M CitiCertificates, in each case for
                              so long as they are outstanding. 

                            With respect to any Distribution Date subsequent to
                              the first Distribution Date, the availability of
                              the credit enhancement provided by the Class M and
                              Class B CitiCertificates will be affected by the
                              prior reduction of the Stated Amount of the Class
                              M and Class B CitiCertificates, which reduction
                              will result from (i) the prior allocation of
                              losses to the Class M and Class B CitiCertificates
                              due to the liquidation of defaulted Mortgage

                              Subordination Level" is the percentage obtained by
                              dividing the Class B Stated Amount by the Pool
                              Adjusted Balance, each as of the immediately
                              preceding Distribution Date (after giving effect
                              to any distributions in reduction of Stated Amount
                              and the allocation of any losses on such date).
                              The Class M Subordination Level on the Closing
                              Date is expected to be between 1.25% and 3.25%. 

                            In the event that on any Distribution Date, the
                              Current Class M Subordination Level equals or
                              exceeds its original percentage but the Current
                              Class B-1 Subordination Level is less than the
                              Class B-1 Subordination Level on the Closing Date,
                              then the Class B-2, Class B-3, Class B-4 and Class

                              will instead be allocated in reduction of the

                              any losses on such date). The Class B-1
                              Subordination Level on the Closing Date is
                              expected to be between 0.80% and 1.80%. 

                            In the event that on any Distribution Date, the
                              Current Class M and Class B-1 Subordination Levels
                              equal or exceed their original percentages but the

                            In addition, in the case of the Class B-3 or Class
                              B-4 CitiCertificates, if on any Distribution Date
                              the percentage obtained by dividing the

DISTRIBUTIONS WITH 
 RESPECT TO THE RETAIL
 CITICERTIFICATES
 A. GENERAL ............... The Class A-11 CitiCertificates will be Retail
                              CitiCertificates. On each Distribution Date on
                              which amounts are available for distributions in

                              CitiCertificates, the aggregate amount allocable
                              to such distributions will be rounded, as
                              necessary, to an amount equal to an integral
                              multiple of $1,000, except as provided below, in
                              accordance with the

                              priorities and limitations set forth herein. Such
                              rounding will be accomplished on the first
                              Distribution Date on which distributions in
                              reduction of Stated Amount of the Retail
                              CitiCertificates are made by withdrawing, from a
                              deposit of $999.99 to be made to a non-interest
                              bearing account on the Closing Date (the "Retail
                              Cash Deposit"), the amount of funds, if any,
                              needed to round the amount otherwise available for
                              such distribution upward to the next higher
                              integral multiple of $1,000. On each succeeding
                              Distribution Date on which distributions in
                              reduction of Stated Amount of the Retail
                              CitiCertificates are to be made, the aggregate
                              amount allocable to the Retail CitiCertificates
                              will be applied first to repay any funds withdrawn
                              from the Retail Cash Deposit on the prior
                              Distribution Date, and then the remainder of such
                              allocable amount, if any, will be similarly
                              rounded upward and distributed in reduction of
                              Stated Amount of the Retail CitiCertificates. This
                              process will continue on succeeding Distribution
                              Dates until the remaining Stated Amount of the
                              Retail CitiCertificates has been reduced to zero.
                              Thus, the aggregate distribution made in reduction
                              of Stated Amount of the Retail CitiCertificates on
                              each Distribution Date (other than on the first
                              Distribution Date on which such distributions are
                              made) may be slightly more or less than would be
                              the case in the absence of such rounding
                              procedures, but such difference will be no more
                              than $999.99 on such Distribution Date. Under no
                              circumstances will the sum of all distributions
                              made in reduction of Stated Amount of the Retail
                              CitiCertificates, through any Distribution Date,
                              be less than the sum that would have resulted in
                              the absence of such rounding procedures. 

                            Because the rate of distributions made in reduction
                              of Stated Amount of the Retail CitiCertificates
                              (in the aggregate) is dependent upon the rate of
                              principal payments (including prepayments) on the
                              Mortgage Loans, no assurance can be given as to
                              the Distribution Date on which the Retail
                              CitiCertificates will begin to receive such
                              distributions, the rate at which such
                              distributions will be made thereafter or the date
                              on which the Stated Amount of the Retail
                              CitiCertificates will be reduced to zero. See
                              "DESCRIPTION OF THE OFFERED CITICERTIFICATES--The
                              Retail CitiCertificates" in this Prospectus
                              Supplement.

                              contrary, on and after the Subordination Depletion
                              Date or if the Insurer fails to make an Insured
                              Payment, distributions in reduction of Stated
                              Amount of the Retail CitiCertificates will
                              thereafter be made pro rata among the holders of
                              the Retail CitiCertificates and shall no longer be
                              made in integral multiples of $1,000 or pursuant
                              to requested distributions or mandatory
                              distributions by random lot. 

                            The Retail CitiCertificates are subject to payment
                              in full in the eventof any early termination at

                            THE RETAIL CITICERTIFICATES MAY NOT BE A SUITABLE

                              NOT AN APPROPRIATE INVESTMENT FOR ANY INVESTOR WHO
                              REQUIRES A SINGLE LUMP SUM PAYMENT ON A

                              TO SELL A RETAIL CITICERTIFICATE WILL BE EQUAL TO

                              make such distributions on any Distribution Date
                              will be limited, there is no assurance that a
                              Beneficial Owner who has submitted a request for a
                              distribution will have such a distribution made
                              with respect to such Retail CitiCertificate within
                              a reasonable period of time after such request is
                              submitted. 

C. MANDATORY DISTRIBUTIONS 
  IN REDUCTION OF STATED
  AMOUNT OF THE RETAIL
  CITICERTIFICATES ........ To the extent that the portion of the Class A
                              Principal Distribution Amount allocated to the
                              Retail CitiCertificates on a Distribution Date
                              plus any Insured Payment applied in reduction of
                              the Stated Amount of the Retail CitiCertificates
                              exceeds the Stated Amount of Retail
                              CitiCertificates for which requests for
                              distributions have been timely received,
                              additional Retail CitiCertificates will be
                              selected for mandatory distributions. On each
                              Distribution Date, the Retail CitiCertificates to
                              receive mandatory distributions in reduction of
                              Stated Amount will be determined in accordance
                              with the then applicable established random lot
                              procedures of DTC and the other established
                              procedures of the Participants or Indirect
                              Participants representing the Beneficial Owners of
                              the Retail CitiCertificates. Accordingly, a
                              Participant or Indirect Participant may determine
                              to make a distribution in reduction of Stated
                              Amount of the Retail CitiCertificates held in the
                              account of some Beneficial Owners (which could
                              include such Participant or Indirect Participant)
                              without making similar distributions with respect
                              to Retail CitiCertificates held in the account of
                              other Beneficial Owners. See "DESCRIPTION OF THE
                              OFFERED CITICERTIFICATES--Distributions in

LAST SCHEDULED 
  DISTRIBUTION DATE ....... The Last Scheduled Distribution Date for the Offered
                              CitiCertificates coincides with the date on which
                              the last distribution in respect of the Mortgage
                              Loans is scheduled to be made. See "DESCRIPTION OF
                              THE OFFERED CITICERTIFICATES--Weighted Average
                              Lives of the Offered CitiCertificates" in this
                              Prospectus Supplement. Since the rate of payment
                              (including prepayments) of principal on the
                              Mortgage Loans can be expected to exceed the
                              scheduled rate of payments, and could exceed the
                              scheduled rate by a substantial amount, the actual
                              final Distribution Date for the Offered
                              CitiCertificates may be earlier, and could be
                              substantially earlier, than the Last Scheduled
                              Distribution Date. 

                            The Offered CitiCertificates are subject to early
                              termination by CMSI as described under
                              "DESCRIPTION OF THE OFFERED
                              CITICERTIFICATES--Optional Termination" in this
                              Prospectus Supplement. 

PREPAYMENT AND YIELD
 CONSIDERATIONS ........... The yield to maturity and weighted average lives of
                              the Offered CitiCertificates will be sensitive in
                              varying degrees to, among other things, the rate
                              of prepayment of the Mortgage Loans, the
                              allocation of such prepayments to the
                              CitiCertificates, and the timing and extent of
                              losses, if any, allocated to the CitiCertificates.
                              No representation is made as to whether the
                              Mortgage Loans will prepay at any particular rate.
                              See "DESCRIPTION OF THE OFFERED
                              CITICERTIFICATES--Weighted Average Lives of the
                              Offered CitiCertificates" and "--Prepayment and
                              Yield Considerations" in this Prospectus
                              Supplement. 

                            The yield to maturity on the Offered Class B
                              CitiCertificates will be more sensitive to losses
                              due to liquidations of the Mortgage Loans (and the
                              timing thereof) than the Class A, Unoffered Class
                              A-IO and Class M CitiCertificates, in the event
                              that the Stated Amount of the Unoffered Class B
                              CitiCertificates has been reduced to zero. The
                              yield to maturity on the Class M CitiCertificates
                              will be more sensitive to losses due to
                              liquidations of the Mortgage Loans (and the timing
                              thereof) than the Class A and Unoffered Class A-IO
                              CitiCertificates in the event that the Stated
                              Amount of the Class B CitiCertificates has been
                              reduced to zero. See "DESCRIPTION OF THE OFFERED
                              CITICERTIFICATES--Prepayment and Yield
                              Considerations" and "--Yield Considerations With
                              Respect to the Offered Class B CitiCertificates"
                              in this Prospectus Supplement. 

                            The yield on the Class A-7 CitiCertificates, which
                              are expected to be offered at a substantial
                              discount and which are not entitled to
                              distributions in respect of interest, will be
                              extremely sensitive to both the timing of receipt
                              of prepayments and the overall rate of prepayment
                              on the Mortgage Loans. A low rate of principal
                              payments (including prepayments) on the Mortgage
                              Loans will have a negative effect and a high rate
                              of principal payments (including prepayments) on
                              the Mortgage Loans will have a positive effect on
                              the yield to investors in the Class A-7
                              CitiCertificates. See "DESCRIPTION OF THE OFFERED

                              The yield on the Class A-14 CitiCertificates,
                              which are expected to be offered at a substantial

                              distributions in respect of interest, will be
                              extremely sensitive to both the timing of receipt
                              of prepayments and the overall rate of prepayment
                              on the Discount Mortgage Loans. A low rate of
                              principal payments (including prepayments) on the
                              Discount Mortgage Loans will have a negative
                              effect and a high rate of principal payments
                              (including prepayments) on the Discount Mortgage
                              Loans will have a positive effect on the yield to
                              investors in the Class A-14 CitiCertificates.
                              Because payments on the Class A-14
                              CitiCertificates are directly related to the rate
                              of principal payment on the Discount Mortgage
                              Loans, the rate of principal payment on the Class
                              A-14 CitiCertificates will be different and most
                              likely will be slower than that of otherClass A
                              CitiCertificates. See "DESCRIPTION OF THE OFFERED
                              CITICERTIFICATES--Prepayment and Yield
                              Considerations" and "--Sensitivity of the Class
                              A-14 CitiCertificates" in thisProspectus
                              Supplement. 

                            The holders of the Class A-13 CitiCertificates will
                              not be entitled to receive any distributions in
                              reduction of Stated Amount prior to the
                              Distribution Date in August 2003, and prior to the
                              Distribution Date in August 2007 will receive a
                              disproportionately small portion of principal
                              prepayments and other unscheduled recoveries on
                              the Mortgage Loans unless the Stated Amounts of
                              all other Class A Subclasses (other than the Class
                              A-14 CitiCertificates) have been reduced to zero
                              or the Stated Amounts of the Subordinated
                              CitiCertificates have been reduced to zero. As a
                              result, the weighted average life will be longer,
                              and could be significantly longer, than would be
                              the case if the Class A-13 CitiCertificates
                              received their pro rata share of the Class A
                              Percentage and Class A Prepayment Percentage of
                              the Non-PO Percentage of all principal payments
                              received on the Mortgage Loans. 

                            AN INVESTOR THAT PURCHASES ANY OFFERED
                              CITICERTIFICATE AT A DISCOUNT SHOULD CAREFULLY
                              CONSIDER THE RISK THAT A SLOWER THAN ANTICIPATED
                              RATE OF PRINCIPAL PAYMENTS ON THE MORTGAGE LOANS
                              WILL RESULT IN AN ACTUAL YIELD THAT IS LOWER THAN
                              SUCH INVESTOR'S EXPECTED YIELD. AN INVESTOR THAT
                              PURCHASES ANY OFFERED CITICERTIFICATE AT A PREMIUM
                              AND ANY CLASS A-12 CITICERTIFICATES, WHICH HAVE NO
                              STATED AMOUNT, SHOULD CONSIDER THE RISK THAT A
                              FASTER THAN ANTICIPATED RATE OF PRINCIPAL PAYMENTS
                              ON THE MORTGAGE LOANS WILL RESULT IN AN ACTUAL
                              YIELD THAT IS LOWER THAN SUCH INVESTOR'S EXPECTED
                              YIELD.

THE MORTGAGE LOANS
 A. GENERAL ............... The Mortgage Loans will have mortgage rates ranging
                              from 6.375% to 8.500% per annum. The initial
                              weighted average mortgage rate of the Mortgage
                              Loans is expected to be at least 7.187% but no
                              more than 7.587% per annum. The weighted average
                              remaining term to stated maturity of the Mortgage

                            The Mortgage Loans will consist of 20- to 30-year
                              fixed rate conventional mortgage loans originated
                              or acquired by CMI and will include loans secured
                              by shares issued by cooperative housing
                              corporations. Mortgage Loans acquired by CMI
                              include Mortgage Loans originated or acquired by
                              CFSB or originated by Citibank. See "DESCRIPTION
                              OF THE POOL AND THE MORTGAGED PROPERTIES" in this

                              information concerning the Mortgage Loans. 

B. CERTIFICATE ACCOUNT .... All payments received in respect of the Mortgage
                              Loans, beginning with the August 1998
                              distribution, will be remitted directly to a
                              certificate account or accounts (the "Certificate
                              Account") to be established with the Trustee on
                              the Closing Date. Such payments will be available
                              for distribution in reduction of Stated Amount of
                              and accrued interest on the CitiCertificates for
                              the Distribution Date on which such funds are
                              remitted to the Certificate Account.

                              Loans and receipts of principal with respect to
                              the Mortgage Loans in an amount less than the
                              decrease in the Pool Adjusted Balance from the
                              prior Distribution Date with respect to a
                              Distribution Date may arise due to losses incurred
                              on Liquidated Loans and to delinquencies not
                              advanced by the Servicer or the Trustee (in its
                              individual capacity). 

                            Realized Losses (other than Excess Special Hazard
                              Losses, Excess Fraud Losses or Excess Bankruptcy
                              Losses) will not be allocated to holders of the
                              Class A CitiCertificates (other than the Class
                              A-14 CitiCertificates) until the Subordination
                              Depletion Date. Prior to such time, the applicable
                              Non-PO Percentage of such Realized Losses will be
                              allocated first to the Class B Subclasses in
                              reverse numerical order until the Stated Amount of
                              each such Class B Subclass has been reduced to
                              zero, and then to the Class M CitiCertificates
                              until the Class M Stated Amount has been reduced
                              to zero. After the Subordination Depletion Date,
                              the principal portion of such Realized Losses
                              allocated to the Class A-11 CitiCertificates will
                              be covered by the Insurance Policy as and to the
                              extent described therein. See "THE INSURANCE
                              POLICY AND THE INSURER" in this Prospectus
                              Supplement. The applicable PO Percentage of such
                              Realized Losses will be allocated to the Class
                              A-14 CitiCertificates as a PO Loss Amount until
                              the Stated Amount thereof has been reduced to
                              zero, but such loss allocation will give rise to
                              the right to receive, in respect of the Class A-14
                              CitiCertificates, reimbursement of losses so
                              allocated first out of certain funds otherwise
                              distributable on the Class B CitiCertificates, and
                              then out of funds otherwise distributable on the
                              Class M CitiCertificates. As a result, any such PO
                              Loss Amounts will ultimately be borne by the Class
                              B Subclasses, in reverse numerical order, and then
                              by the Class M CitiCertificates, in each case for
                              so long as they are outstanding. 

                            The applicable Non-PO Percentage of the principal
                              portion of any Excess Special Hazard Loss, Excess
                              Fraud Loss or Excess Bankruptcy Loss will be
                              allocated among the Class A Subclasses (other than
                              the Class A-14 CitiCertificates), the Class M
                              CitiCertificates and the Class B Subclasses. Any
                              such allocation will be accomplished by reducing
                              the outstanding Stated Amount of each such Class A
                              Subclass, the Class M CitiCertificates and each

                              losses will be allocated to the Class A-14
                              CitiCertificates. See "DESCRIPTION OF THE OFFERED

                              Losses or any Excess Bankruptcy Losses, which
                              would result in a reduction of the Stated Amount
                              of the Class A-11 CitiCertificates but for an

                              CitiCertificates, a reduction in Stated Amount of
                              the Class A-11 CitiCertificates will be made in
                              accordance with the priorities stated under

                              make an Insured Payment then such losses will be
                              allocated among the Class A Subclasses pro rata
                              based on, with respect to each Class A Subclass,
                              the then current Stated Amount of such Class A

                            On each Distribution Date occuring on and after the
                              Subordination Depletion Date, holders of Class A
                              CitiCertificates (other than Class A-14
                              CitiCertificates) will generally receive their
                              respective pro rata share of the Non-PO Percentage

                              Percentage of net Liquidation Proceeds realized on
                              Liquidated Loans (in each case, after

                              any previously unreimbursed advances made in
                              respect of such loans). 

ADVANCES .................. The Servicer intends to make advances in respect of
                              delinquencies on the Mortgage Loans in an amount
                              equal to the delinquent payments to the extent the
                              Servicer determines that such advances will be
                              recoverable from future payments and collections
                              on the Mortgage Loans. The Servicer will contract
                              with the Trustee (in its individual capacity and
                              not as Trustee) for the limited purpose of
                              providing for advances by the Trustee (in such
                              individual capacity) in respect of delinquencies
                              to the extent that the Servicer fails to make such
                              advances. The Trustee (in such individual
                              capacity) will make such advances to the extent it
                              determines that such advances will be recoverable
                              from future payments and collections on the
                              related Mortgage Loans. Recoveries in respect of
                              amounts advanced will be applied to reimbursement
                              of the advances. On each Distribution Date, the
                              Servicer and the Trustee will be entitled to

                              made by them, but only (in the case of clause (b))
                              from funds not distributable to holders of
                              CitiCertificates on such Distribution Date.

OPTIONAL TERMINATION ...... Holders of CitiCertificates may receive final
                              distributions in connection with a termination of
                              the Trust made at the option of CMSI on any
                              Distribution Date after which the Pool Adjusted
                              Balance is less than 5% of the Initial Mortgage
                              Loan Balance. The price paid by CMSI for the Trust
                              property will generally equal the sum of (i) 100%
                              of the unpaid principal balance of the Mortgage
                              Loans, together with accrued interest thereon at
                              the NNRs on the respective Mortgage Loans, and
                              (ii) the current appraised value of acquired
                              property. Holders of the CitiCertificates, to the
                              extent of funds available, will receive the unpaid
                              Stated Amount of their CitiCertificates plus
                              accrued and unpaid interest thereon. See
                              "DESCRIPTION OF THE OFFERED
                              CITICERTIFICATES--Optional Termination" in this
                              Prospectus Supplement.

                              the close of business on the last day of the month
                              preceding the month of the applicable Distribution
                              Date.

CERTAIN FEDERAL INCOME 
 TAX CONSEQUENCES ......... For federal income tax purposes, the Trust will be
                              treated as two segregated asset pools. Elections
                              will be made to treat each segregated pool as a
                              separate REMIC for purposes of Sections 860A
                              through 860G of the Code. The Lower-Tier REMIC
                              will issue the Class A-1, Class A-2, Class A-3,
                              Class A-4, Class A-5, Class A-6, Class A-7, Class
                              A-8, Class A-9, Class A-10, Class A-13, Class
                              A-14, and Class M CitiCertificates, each Class B

                              Certificates, each of which will be designated as
                              a regular interest in the Lower-Tier REMIC, and
                              the Upper-Tier REMIC will issue the Class A-11 and
                              Class A-12 CitiCertificates, each of which will be
                              designated as a regular interest in the Upper-Tier
                              REMIC. The Pooling Agreement will require that the
                              Servicer on behalf of the Trust maintain separate
                              books and records for the Lower-Tier and
                              Upper-Tier REMICs for federal income tax purposes
                              and that the Trustee act consistently therewith.
                              The Offered CitiCertificates generally will be
                              treated as newly originated debt instruments for
                              federal income tax purposes. Beneficial Owners (or
                              holders, in the case of the Class A-14
                              CitiCertificates, the Class M CitiCertificates and
                              the Offered Class B CitiCertificates) of the
                              Offered CitiCertificates will be required to
                              report interest income on such Offered
                              CitiCertificates in accordance with the accrual
                              method of accounting. The Class A-7 and Class A-14
                              CitiCertificates will be issued with original
                              issue discount in an amount equal to the excess of
                              their Initial Stated Amounts over their respective
                              issue prices. The Class A-6 CitiCertificates will
                              be issued with original issue discount in an
                              amount equal to the excess of the Initial Stated
                              Amount thereof and all interest distributions
                              (whether current or accrued) expected to be
                              received thereon over their issue price (including
                              accrued interest). It is anticipated that the

                              original issue discount in an amount equal to the

                              price (including accrued interest). It is further
                              anticipated that the Class A-1, Class A-2, Class
                              A-3, Class A-4, Class A-5, Class A-8 and

                              A-13, Class M and Class B-1 CitiCertificates will
                              be issued with de minimis original issue discount
                              for federal income tax purposes. It is further
                              anticipated that the Class A-12 CitiCertificates
                              will be treated as issued with original issue
                              discount for federal income tax purposes in an
                              amount equal to the excess of all distributions of
                              interest expected to be received thereon over
                              their issue price (including accrued interest). In
                              the alternative, it is possible that rules similar
                              to the contingent interest rules of the OID
                              Regulations could be adopted with respect to
                              prepayable securities such as the Class A-12
                              CitiCertificates. See "CERTAIN FEDERAL INCOME TAX

                            The Prepayment Assumption on the Mortgage Loans, as
                              described in the Prospectus, that is to be used,
                              among other things, in determining the rate of
                              accrual of original issue discount is 275% of the
                              Prepayment Model's (as defined herein) assumed
                              prepayment rates. See "DESCRIPTION OF THE OFFERED

                              rate at which the Mortgage Loans will prepay. 

                            The Offered CitiCertificates will be treated as
                              "loans . . . secured by an interest in real
                              property which is . . . residential real property"

                              building and loan associations and as "real estate
                              assets" for real estate investment trusts, to the
                              extent described in the Prospectus, as "qualified
                              mortgages" for another REMIC, and as "permitted
                              assets" for a financial asset securitization
                              investment trust. See "CERTAIN FEDERAL INCOME TAX
                              CONSEQUENCES" in the Prospectus.

CERTIFICATE RATINGS ....... It is a condition of issuance of the Offered
                              CitiCertificates that the Class A CitiCertificates
                              (other than the Class A-7, Class A-12 and Class
                              A-14 CitiCertificates) shall be rated "AAA" by
                              Standard & Poor's Ratings Group ("S&P") and Fitch
                              IBCA, Inc. ("Fitch"); the Class A-7, Class A-12
                              and Class A-14 CitiCertificates shall be rated
                              "AAAr" by S&P and "AAA" by Fitch; the Class M
                              CitiCertificates shall be rated at least "AA" by
                              Fitch; the Class B-1 CitiCertificates shall be
                              rated at least "A" by Fitch; and the Class B-2
                              CitiCertificates shall be rated at least "BBB" by
                              Fitch. Ratings of the Offered CitiCertificates
                              other than those indicated above have not been
                              requested. However, there can be no assurance as
                              to whether another rating agency will rate the
                              Offered CitiCertificates, and, if so, what ratings
                              would be so assigned to the Offered
                              CitiCertificates. The ratings so assigned may be
                              lower than those indicated above.

                            The ratings of the Offered CitiCertificates should
                              be evaluated independently from similar ratings on
                              other types of securities. The ratings do not
                              address the possibility that as a result of
                              prepayments holders of Offered CitiCertificates
                              may receive a lower than anticipated yield. A
                              security rating is not a recommendation to buy,
                              sell or hold securities and may be subject to
                              revision or withdrawal at any time by the
                              assigning rating agency. The "r" symbol in certain
                              S&P ratings is attached to highlight certificates
                              that S&P believes may experience high volatility
                              or high variability in expected returns due to
                              non-credit risks. The absence of an "r" symbol
                              should not be taken as an indication that a
                              certificate will exhibit no volatility or
                              variability in total return.

Trustee (in its individual capacity and not as Trustee) for the limited purpose
of providing for advances by the Trustee (in such individual capacity) in
respect of delinquencies to the extent that the Servicer fails to make any such
advance. The Trustee (in such individual capacity) will make such advances to
the extent it determines that such advances will be recoverable from future
payments and collections on the related Mortgage Loans. To the extent that the
Servicer and the Trustee (in such individual capacity) do not make such
advances, the only source of cash for distributions to holders of
CitiCertificates will be the Pool Distribution Amount.

ALLOCATION OF LOAN LOSSES

     Liquidated Loans: The applicable Non-PO Percentage of Realized Losses on
the Mortgage Loans as a result of losses realized on Liquidated Loans will be
allocated first to the Class B Subclasses in reverse numerical order up to the
Stated Amount of each such Class B Subclass and accrued interest thereon, and
then to the Class M CitiCertificates up to the Stated Amount thereof and accrued
interest thereon. The applicable PO Percentage of Realized Losses will
ultimately be allocated to the Class B Subclasses and the Class M
CitiCertificates, in the manner described in the preceding sentence, by virtue
of the right of the holders of Class A-14 CitiCertificates to receive
reimbursement of PO Loss Amounts out of amounts otherwise distributable in
reduction of Stated Amount of the Class B and Class M CitiCertificates. The
Class A CitiCertificates (other than the Class A-14 CitiCertificates) will be
entitled to receive the Class A Prepayment Percentage of the applicable Non-PO
Percentage of the principal portion of net liquidation proceeds and the Class
A-14 CitiCertificates will be entitled to receive the applicable PO Percentage
of the principal portion of net liquidation proceeds. After the Subordination
Depletion Date, the applicable Non-PO Percentage of Realized Losses will be
allocated among the Class A CitiCertificates (other than the Class A-14
CitiCertificates). Such Realized Losses allocated to the Class A-11
CitiCertifices will be covered by the Insurance Policy.

     Special Hazard Losses: Until the Special Hazard Termination Date, the
applicable Non-PO Percentage of all Special Hazard Losses will reduce the Stated
Amount of and accrued interest on the Class M and Class B CitiCertificates in
the order of priority set forth in the preceding paragraph. The PO Percentage of
such losses will ultimately be allocated to the Class B Subclasses in reverse
numerical order and then the Class M CitiCertificates, as


                                      S-32

<PAGE>

described in the third succeeding paragraph. The Class A CitiCertificates (other
than the Class A-14 CitiCertificates) will be entitled to receive, in respect of
each Mortgage Loan that becomes a Special Hazard Mortgage Loan in the preceding
month, an amount equal to the Class A Prepayment Percentage of the applicable
Non-PO Percentage of the principal portion of the related net liquidation
proceeds, and the Class A-14 CitiCertificates will be entitled to receive an
amount equal to the applicable PO Percentage of the principal portion of such
net liquidation proceeds. After the Special Hazard Termination Date, the
applicable Non-PO Percentage of the principal portion of Excess Special Hazard
Losses will be allocated among the Class A Subclasses (other than the Class A-14
CitiCertificates) and the Class M and Class B CitiCertificates as described
herein under "DESCRIPTION OF THE OFFERED CitiCertificates--Subordination
- --Allocation of Losses" and the PO Percentage of the principal portion of Excess
Special Hazard Losses will be allocated to the Class A-14 CitiCertificates.
Excess Special Hazard Losses allocated to the Class A-11 CitiCertificates will
be covered by the Insurance Policy. Excess Special Hazard Losses are Special
Hazard Losses in excess of the Special Hazard Loss Amount, which will initially
be equal to approximately 2.63% of the Initial Mortgage Loan Balance.

     Fraud Losses: Until the Fraud Coverage Termination Date, the applicable
Non-PO Percentage of all Fraud Losses will reduce the Stated Amount of and
accrued interest on the Class M and Class B CitiCertificates in the order of
priority set forth in the second preceding paragraph. The PO Percentage of such
losses will ultimately be allocated to the Class B Subclasses in reverse
numerical order and then the Class M CitiCertificates, as described in the
second succeeding paragraph. Holders of the Class A CitiCertificates (other than
the Class A-14 CitiCertificates) will be entitled to receive, in respect of each
Mortgage Loan that was subject to a Fraud Loss in the preceding month, an amount
equal to the Class A Prepayment Percentage of the applicable Non-PO Percentage
of the principal portion of the related net liquidation proceeds, and the Class
A-14 CitiCertificates will be entitled to receive an amount equal to the
applicable PO Percentage of the principal portion of such net liquidation
proceeds. After the Fraud Coverage Termination Date, the applicable Non-PO
Percentage of the principal portion of Excess Fraud Losses will be allocated
among the Class A Subclasses (other than the Class A-14 CitiCertificates) and
the Class M and Class B CitiCertificates as described herein under "DESCRIPTION
OF THE OFFERED CITICERTIFICATES--Subordination--Allocation of Losses," and the
PO Percentage of the principal portion of Excess Fraud Losses will be allocated
to the Class A-14 CitiCertificates. Excess Fraud Losses allocated to the Class
A-11 CitiCertificates will be covered by the Insurance Policy. Excess Fraud
Losses are Fraud Losses in excess of the Fraud Loss Amount, which will initially
be equal to approximately 1.00% of the Initial Mortgage Loan Balance.

     Bankruptcy Losses: Until the Bankruptcy Coverage Termination Date, the
applicable Non-PO Percentage of all Bankruptcy Losses will reduce the Stated
Amount of and accrued interest on the Class M and Class B CitiCertificates in
the order of priority set forth in the third preceding paragraph. The PO
Percentage of such losses will ultimately be allocated to the Class B Subclasses
in reverse numerical order and then the Class M CitiCertificates, as described
in the next succeeding paragraph. On each Distribution Date occurring prior to
the Bankruptcy Coverage Termination Date, the Stated Amount of the Class M and
Class B CitiCertificates will be reduced, in respect of each Mortgage Loan that
was subject to a Bankruptcy Loss in the preceding month, in an amount equal to
the applicable Non-PO Percentage of the principal portion of such Bankruptcy
Loss. After the Bankruptcy Coverage Termination Date, the applicable Non-PO
Percentage of the principal portion of Excess Bankruptcy Losses will be
allocated among the Class A Subclasses (other than the Class A-14
CitiCertificates) and Class M and Class B CitiCertificates as described herein
under "DESCRIPTION OF THE OFFERED CITICERTIFICATES--Subordination--Allocation of
Losses" and the PO Percentage of Excess Bankruptcy Losses will be allocated to
the Class A-14 CitiCertificates. Excess Bankruptcy Losses allocated to the Class
A-11 CitiCertificates will be covered by the Insurance Policy. Excess Bankruptcy
Losses are Bankruptcy Losses in excess of the Bankruptcy Loss Amount, which will
initially be equal to approximately 0.03% of the Initial Mortgage Loan Balance.

     Until the Special Hazard Termination Date, Fraud Coverage Termination Date
and Bankruptcy Coverage Termination Date, the applicable PO Percentage of
Special Hazard Losses, Fraud Losses and Bankruptcy Losses will first be
allocated to the Class B Subclasses in reverse numerical order and then to the
Class M CitiCertificates by virtue of the right of the holders of the Class A-14
CitiCertificates to receive reimbursement of PO Loss Amounts out of amounts
otherwise distributable in reduction of the Stated Amount of the Class B and
Class M CitiCertificates.

     The exact amounts of Special Hazard Losses, Fraud Losses and Bankruptcy
Losses to be allocated to the Class M and Class B CitiCertificates (in each case
only prior to the related termination date) will be those amounts required by


                                      S-33

<PAGE>

the rating agency (or rating agencies) rating the Offered CitiCertificates as a
condition of the ratings set forth in "SUMMARY OF PROSPECTUS AND PROSPECTUS
SUPPLEMENT--Certificate Ratings" in this Prospectus Supplement.

     The interest portion of any Excess Special Hazard Losses, Excess Fraud
Losses and Excess Bankruptcy Losses will be allocated pro rata among the
CitiCertificates (other than the Class A-7 and Class A-14 CitiCertificates)
based on interest accrued on such CitiCertificates. Any such losses allocated to
the Class A-11 CitiCertificates will be covered by the Insurance Policy.

EFFECT OF LOSSES AND OTHER SHORTFALLS

     The ultimate payment to holders of Class M and Offered Class B
CitiCertificates of the Stated Amount thereof is dependent upon the timing and
the level of losses realized on the Mortgage Loans and other shortfalls in
distributions on the Mortgage Loans. Special Hazard Losses (up to the Special
Hazard Loss Amount), Fraud Losses (up to the Fraud Loss Amount) and Bankruptcy
Losses (up to the Bankruptcy Loss Amount) and other Realized Losses on
Liquidated Loans will be allocated first to the Unoffered Class B
CitiCertificates, second to the Class B-2 CitiCertificates, third to the Class
B-1 CitiCertificates and then to the Class M CitiCertificates until the
Subordination Depletion Date.

     To the extent that all such amounts and shortfalls are allocated as
described above, holders of the Class M and Offered Class B CitiCertificates may
experience shortfalls in distributions of interest and may not receive
distributions equal to the Initial Stated Amount of their CitiCertificates and
may, depending on the purchase price of such CitiCertificates, suffer a
reduction in yield or experience a loss on their investment in the Class M or
Offered Class B CitiCertificates, as the case may be.

RESTRICTIONS ON TRANSFER

     Under current law, the purchase and holding of the Class M CitiCertificates
and the Offered Class B CitiCertificates by or on behalf of a Plan may result in
"prohibited transactions" within the meaning of ERISA and Code Section 4975 or
Similar Law. A transfer of the Class M CitiCertificates and the Offered Class B
CitiCertificates will not be registered by the Trustee unless the transferee (i)
executes a representation letter in form and substance satisfactory to the
Trustee stating either (a) that it is not, and is not acting on behalf of, any
such Plan or using the assets of any such Plan to effect such purchase or (b)
subject to certain conditions described herein, that the source of funds used to
purchase the Class M or Offered Class B CitiCertificates, as the case may be, is
an "insurance company general account" or (ii) provides (A) an opinion of
counsel in form and substance satisfactory to the Trustee and the Issuer that
the purchase or holding of the Class M CitiCertificates or the Offered Class B
CitiCertificates by or on behalf of such Plan will not result in the assets of
the Trust being deemed to be "plan assets" and subject to the prohibited
transaction provisions of ERISA and the Code or Similar Law and will not subject
the Servicer (or its designee), the Issuer or the Trustee to any obligation in
addition to those undertaken in the Pooling Agreement and (B) such other
opinions of counsel, officers' certificates and agreements as the Trustee and
the Issuer may require in connection with such transfer.

LEGAL INVESTMENT

     Institutions whose investment activities are subject to legal investment
laws and regulations or to review by certain regulatory authorities may be
subject to restrictions on investment in the Class M and the Offered Class B
CitiCertificates. The Issuer makes no representations or warranties concerning
whether the Class M or the Offered Class B CitiCertificates are legal
investments under any federal or state law, regulation, rule or order of any
court. The Offered Class B CitiCertificates will not constitute "mortgage
related securities" within the meaning of SMMEA. The Class M CitiCertificates
will qualify at issuance as "mortgaged related securities." Prospective
investors are advised to consult their counsel as to qualification of the Class
M and the Offered Class B CitiCertificates as legal investments under any such
laws, regulations, rules and orders.

                   DESCRIPTION OF THE OFFERED CITICERTIFICATES

     The Offered CitiCertificates will be issued pursuant to the Pooling
Agreement, a form of which is filed as an exhibit to the Registration Statement
of which this Prospectus Supplement is a part. The Trustee will make available
for inspection a copy of the Pooling Agreement (without attachments) to holders
of CitiCertificates upon written request. Reference is made to the Prospectus
for important additional information regarding the terms and conditions of the
Pooling Agreement and the CitiCertificates. Each Class A and Class M
CitiCertificate at the time of issuance will qualify as a "mortgage related
security" within the meaning of SMMEA and will retain such qualification so long
as it is rated in one of the two highest rating categories by at least one
nationally recognized statistical rating organization.

     Distributions on the Offered CitiCertificates generally will be made by the
Trustee by wire transfer (if wiring instructions are received from the Person
entitled thereto) in the case of a holder of Offered CitiCertificates having an
aggregate Initial Stated Amount (or notional amount) of $1,000,000 or more, or
by check or by such other means as the Person entitled thereto and the Trustee
shall agree. Unless and until Definitive Certificates are issued, Cede, as
nominee of DTC, will be the holder of the Book-Entry CitiCertificates. However,
the final distribution in reduction of Stated Amount will be made only upon
presentation and surrender of such CitiCertificate at the office of the Trustee.
Payments will be made to or for the account of the Person entitled thereto or as
specified by such Person in accordance with the terms of the Pooling Agreement.

DISTRIBUTIONS OF INTEREST

     The amount of interest that will be distributable with respect to each
Class A Subclass during each Interest Accrual Period is referred to herein as
the "Class A Subclass Interest Amount" for such Class A Subclass. The Class A
Subclass Interest Amount for each Class A Subclass (other than the Class A-7 and
Class A-14 CitiCertificates) will equal the interest accrued for each Interest
Accrual Period at the applicable Stated Rate set forth on the cover page hereof
on the Class A Subclass Stated Amount of such Class A Subclass (or in the case
of the Class A-12 CitiCertificates, the Class A-12 Notional Amount), reduced by
(i) the portion of any Non-Supported Interest Shortfall allocable to such Class
A Subclass and (ii) the interest portion of Excess Special Hazard Losses, Excess
Fraud Losses and Excess Bankruptcy Losses allocable to such Class A Subclass as
described below. The Class A-7 and Class A-14 CitiCertificates will not bear
interest. The sum of the Class A Subclass Interest Amounts for a particular
Distribution Date is the "Class A Interest Amount."

     The amount of interest to which holders of the Class A-12 CitiCertificates
are entitled is based on a notional amount (the "Class A-12 Notional Amount").
The Class A-12 Notional Amount does not entitle the holders of Class A-12
CitiCertificates to receive distributions of principal on the basis of such
notional amount but is used solely for purposes of computing the amount of
interest accrued on the Class A-12 CitiCertificates. The Class A-12 Notional
Amount on any date will be equal to the Stated Amount of the Class A-11
CitiCertificates as of such date.

     An amount of interest equal to the Unoffered Class A-IO Interest Amount
will accrue on the Unoffered Class A-IO CitiCertificates during each Interest
Accrual Period. On each Distribution Date, to the extent funds are available,
the Distributable Unoffered Class A-IO Interest Amount will be distributed to
the Unoffered Class A-IO CitiCertificates.

     The amount of interest that will be distributable with respect to the Class
M CitiCertificates during each Interest Accrual Period is referred to herein as
the "Class M Interest Amount." The Class M Interest Amount will equal the
interest accrued for an Interest Accrual Period at a rate of 6.50% per annum on
the Class M Stated Amount, reduced by (i) the portion of any Non-Supported
Interest Shortfall allocable to the Class M CitiCertificates and (ii) the
interest portion of Excess Special Hazard Losses, Excess Fraud Losses and Excess
Bankruptcy Losses allocable to the Class M CitiCertificates as described below.

     The amount of interest that will be distributable with respect to each
Offered Class B Subclass and each Unoffered Class B Subclass during each
Interest Accrual Period is referred to herein, respectively, as the "Offered
Class B Subclass Interest Amount" and the "Unoffered Class B Subclass Interest
Amount." The Offered and Unoffered Class B Subclass Interest Amount will equal
the interest accrued for an Interest Accrual Period at the rate of 6.50% per
annum on the Stated Amount of such Class B Subclass, in each case reduced by (i)
the portion of any Non-Supported Interest Shortfall allocable to such Class B
Subclass and (ii) the interest portion of Excess Special


                                      S-35

<PAGE>

Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses allocable to
such Class B Subclass as described below. The sum of the Offered Class B
Subclass Interest Amounts as of any Distribution Date is the "Offered Class B
Interest Amount" and the sum of the Unoffered Class B Subclass Interest Amounts
as of any Distribution Date is the "Unoffered Class B Interest Amount." The sum
of the Offered Class B Interest Amount and the Unoffered Class B Interest Amount
for a particular Distribution Date is the "Class B Interest Amount."

     The "Class A Subclass Stated Amount" of a Class A Subclass (other than the
Class A-4 and Class A-5 CitiCertificates, the Class A-12 CitiCertificates, which
have no Stated Amount, and the Class A-14 CitiCertificates) as of any
Distribution Date before the Subordination Depletion Date will be the Initial
Stated Amount of such Class A Subclass (plus, in the case of the Class A-6
CitiCertificates, all Accretion Distribution Amounts previously added to the
Stated Amount thereof) less (i) all amounts previously distributed to holders of
CitiCertificates of such Class A Subclass in reduction of the Stated Amount of
such Class A Subclass and (ii) such Class A Subclass's pro rata share of the
applicable Non-PO Percentage of the principal portion of Excess Special Hazard
Losses, Excess Fraud Losses and Excess Bankruptcy Losses previously allocated to
the Class A CitiCertificates (other than the Class A-14 CitiCertificates) in the
manner described below under "--Subordination--Allocation of Losses." After the
Subordination Depletion Date, the Class A Subclass Stated Amount of such Class A
CitiCertificates may be subject to further reduction in an amount equal to such
Class A Subclass's pro rata share of the difference, if any, between (a) the
Class A Stated Amount (after subtracting the Class A Subclass Stated Amount of
the Class A-14 CitiCertificates) as of such Distribution Date without regard to
this provision and (b) the sum of the products of the applicable Non-PO
Percentage of each Mortgage Loan and the Adjusted Balance of such Mortgage Loan
for the preceding Distribution Date (the "Non-PO Pool Adjusted Balance"). Any
pro rata allocation described in this paragraph will be made among the Class A
Subclasses (other than the Class A-4 and Class A-5 CitiCertificates, the Class
A-12 CitiCertificates, which have no Stated Amount, and the Class A-14
CitiCertificates) and the Components on the basis of their then outstanding
Class A Subclass Stated Amounts and Component Stated Amounts as of the preceding
Distribution Date (or, in the case of the Class A-6 CitiCertificates, the
Initial Stated Amount, if lower).

     The Class A Subclass Stated Amount with respect to the Class A-4
CitiCertificates is equal to the sum of the Component Stated Amounts of the
Class A-4 CitiCertificate (Component 1) and the Class A-4 CitiCertificate
(Component 2). The Class A Subclass Stated Amount of the Class A-5
CitiCertificates is equal to the sum of the Component Stated Amounts of the
Class A-5 CitiCertificate (Component 1) and the Class A-5 CitiCertificate
(Component 2).

     The "Component Stated Amount" of a Component as of any Distribution Date
before the Subordination Depletion Date will be the initial Component Stated
Amount of such Component less (i) all amounts previously distributed to holders
of the Class A-4 or Class A-5 CitiCertificates, as the case may be, in respect
of such Component in reduction of the Component Stated Amount of such Component
and (ii) such Component's pro rata share of the applicable Non-PO Percentage of
the principal portion of Excess Special Hazard Losses, Excess Fraud Losses and
Excess Bankruptcy Losses previously allocated to the Class A CitiCertificates
(other than the Class A-14 CitiCertificates) in the manner described below under
"--Subordination--Allocation of Losses." After the Subordination Depletion Date,
the Component Stated Amount of such Component may be subject to further
reduction in an amount equal to such Component's pro rata share of the
difference, if any, between (a) the Class A Stated Amount (after subtracting the
Class A Subclass Stated Amount of the Class A-14 CitiCertificates) as of such
Distribution Date without regard to this provision and (b) the Non-PO Pool
Adjusted Balance. Any pro rata allocation described in this paragraph will be
made among the Class A Subclasses (other than the Class A-4 and Class A-5
CitiCertificates, the Class A-12 CitiCertificates, which have no Stated Amount,
and the Class A-14 CitiCertificates) and the Components on the basis of their
then outstanding Class A Subclass Stated Amounts and Component Stated Amounts as
of the preceding Distribution Date (or, in the case of the Class A-6
CitiCertificates, the Initial Stated Amount, if lower).

     The Class A Subclass Stated Amount of the Class A-14 CitiCertificates as of
any Distribution Date will be equal to the difference between the Pool Adjusted
Balance and the Non-PO Pool Adjusted Balance as of such date.

     With respect to each Distribution Date prior to the Subordination Depletion
Date, the "PO Loss Amount" for such Distribution Date will equal the sum of (i)
the difference, if any, between the Class A PO Principal Amount for such
Distribution Date and the amount distributed in reduction of the Stated Amount
of the Class A-14 CitiCertificates on such Distribution Date and (ii) the
applicable PO Percentage of each Realized Loss (other than


                                      S-36

<PAGE>

Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses).
On and after the Subordination Depletion Date, Available PO Loss Funds will be
zero and will therefore not be available for reimbursement of PO Loss Amounts.

     The "Class A Stated Amount" as of any Distribution Date will be equal to
the sum of the Class A Subclass Stated Amounts as of such date. The Class A-12
CitiCertificates are interest-only certificates and, accordingly, have no Stated
Amount.

     The "Class M Stated Amount" as of any Distribution Date will be equal to
the lesser of (a) the Initial Stated Amount of the Class M CitiCertificates less
(i) all amounts previously distributed to holders thereof in reduction of Stated
Amount and (ii) such Class's pro rata share of the Non-PO Percentage of the
principal portion of Excess Special Hazard Losses, Excess Fraud Losses and
Excess Bankruptcy Losses previously allocated to the Class M CitiCertificates in
the manner described below under "--Subordination--Allocation of Losses" and (b)
the Pool Adjusted Balance minus the Class A Stated Amount, each as of the
immediately preceding Distribution Date (after taking into account distributions
in reduction of Stated Amount and the allocation of any Excess Special Hazard
Losses, Excess Fraud Losses and Excess Bankruptcy Losses on such date).

     The "Offered Class B Subclass Stated Amount" of an Offered Class B Subclass
as of any Distribution Date will be the lesser of (a) the Initial Stated Amount
of such Offered Class B Subclass less (i) all amounts previously distributed to
holders of CitiCertificates of such Offered Class B Subclass in reduction of the
Stated Amount thereof and (ii) such Offered Class B Subclass's pro rata share of
the Non-PO Percentage of the principal portion of Excess Special Hazard Losses,
Excess Fraud Losses and Excess Bankruptcy Losses previously allocated to holders
of the Class B CitiCertificates in the manner described below under
"--Subordination--Allocation of Losses" and (b) the Pool Adjusted Balance minus
the sum of the Class A Stated Amount and the Class M Stated Amount and, in the
case of a particular Offered Class B Subclass, the aggregate Stated Amount of
the Offered Class B Subclasses having a lower numerical designation, each as of
the immediately preceding Distribution Date (after taking into account
distributions in reduction of Stated Amount and the allocation of any Excess
Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses on such
date). The "Offered Class B Stated Amount" as of any Distribution Date will be
equal to the sum of the Offered Class B Subclass Stated Amounts as of such date.

     The "Unoffered Class B Subclass Stated Amount" of any Unoffered Class B
Subclass as of any Distribution Date will be the lesser of (a) the Initial
Stated Amount of such Unoffered Class B Subclass less (i) all amounts previously
distributed to holders of CitiCertificates of such Unoffered Class B Subclass in
reduction of the Stated Amount thereof and (ii) such Unoffered Class B
Subclass's pro rata share of the applicable Non-PO Percentage of the principal
portion of Excess Special Hazard Losses, Excess Fraud Losses and Excess
Bankruptcy Losses previously allocated to holders of the Unoffered Class B
CitiCertificates in the manner described below under
"--Subordination--Allocation of Losses" and (b) the Pool Adjusted Balance minus
the sum of the Class A Stated Amount, the Class M Stated Amount, the Offered
Class B Stated Amount and the Unoffered Class B Subclass Stated Amount of each
Unoffered Class B Subclass with a lower numerical designation, each as of the
immediately preceding Distribution Date (after taking into account distributions
in reduction of Stated Amount and the allocation of any Excess Special Hazard
Losses, Excess Fraud Losses and Excess Bankruptcy Losses on such date). The
"Unoffered Class B Stated Amount" as of any Distribution Date will be the
aggregate of the Unoffered Class B Subclass Stated Amounts as of such date. The
"Class B Stated Amount" as of any Distribution Date will be the Pool Adjusted
Balance less the sum of the Class A Stated Amount and the Class M Stated Amount
and will equal the sum of the Offered Class B Stated Amount and the Unoffered
Class B Stated Amount.

     With respect to any Distribution Date, the "Pool Adjusted Balance" will
equal the aggregate Adjusted Balances of the Mortgage Loans as of such
Distribution Date.

     Interest shortfalls resulting from full or partial principal prepayments of
Mortgage Loans ("Prepayment Interest Shortfalls") will be offset to the extent
of the Compensating Cap on the related Distribution Date. The aggregate
Prepayment Interest Shortfalls with respect to a Distribution Date in excess of
the Compensating Cap (the "Non-Supported Interest Shortfall") will be allocated
pro rata among the Classes of CitiCertificates based on interest accrued on each
such Class and accordingly will reduce the amount of interest due to be
distributed to holders of the CitiCertificates then entitled to distributions in
respect of interest. Any such reduction in respect of interest allocated to the
Class A and Class B CitiCertificates will be allocated among the Class A
Subclasses (other than the Class A-7 and Class A-14 CitiCertificates) and the
Class B Subclasses, respectively, pro rata on the basis of their respective


                                      S-37

<PAGE>

amounts of accrued interest for such Distribution Date. Any Non-Supported
Interest Shortfalls and other losses allocated to the Class A-11
CitiCertificates will be covered by either the Reserve Fund or the Insurance
Policy as and to the extent described below. See "THE INSURANCE POLICY AND THE
INSURER" in this Prospectus Supplement.

     A single reserve fund will be established at the time of the issuance of
the Class A-11 CitiCertificates (the "Reserve Fund") by an initial deposit into
a separate account maintained by the Trustee of approximately $7,000. No
additional amounts will be deposited into the Reserve Fund after the initial
deposit. The Reserve Fund will be beneficially owned by Lehman Brothers Inc. and
will not be an asset of the Trust, the Upper-Tier REMIC or the Lower-Tier REMIC.

     A withdrawal will be made on each Distribution Date from the amount on
deposit in the Reserve Fund, to the extent available, to cover any Non-Supported
Interest Shortfalls allocated to the Class A-11 CitiCertificates. A withdrawal
from the Reserve Fund may only be made, to the extent funds are available
therein, to cover any Non-Supported Interest Shortfall allocated to such
Subclass and may not be made to cover any Non-Supported Interest Shortfall
allocated to any other Subclass. Once the Reserve Fund has been reduced to zero,
the Insurance Policy will cover any Non-Supported Interest Shortfalls allocated
to the Class A-11 CitiCertificates.

     The balance of any amount remaining in the Reserve Fund on the Distribution
Date on which the Stated Amount of the Class A-11 CitiCertificates is reduced to
zero will be distributed to Lehman Brothers Inc.

     The interest portion of any Excess Special Hazard Losses, Excess Fraud
Losses or Excess Bankruptcy Losses with respect to a Mortgage Loan will be
allocated pro rata among the Classes of CitiCertificates based on the amount of
interest accrued on each such Class and among the Class A Subclasses (other than
the Class A-7 and Class A-14 CitiCertificates), and among the Class B
Subclasses, respectively, pro rata on the basis of their respective amounts of
interest accrued for such Distribution Date. Any such losses allocated to the
Class A-11 CitiCertificates will be covered by the Insurance Policy.

     Allocations of the interest portion of Realized Losses (other than Excess
Special Hazard Losses, Excess Fraud Losses or Excess Bankruptcy Losses) first to
the Class B CitiCertificates in reverse numerical order, then to the Class M
CitiCertificates and then to the Class A and Unoffered Class A-IO
CitiCertificates will result from the priority of distributions first to the
Class A and Unoffered Class A-IO CitiCertificateholders, then to the Class M
CitiCertificateholders and then to the Class B CitiCertificateholders of the
Pool Distribution Amount. After the Subordination Depletion Date, the interest
portion of Realized Losses will be deducted from interest accrued on the
CitiCertificates. Any such losses allocated to the Class A-11 CitiCertificates
will be covered by the Insurance Policy.

     On each Distribution Date, prior to the Subordination Depletion Date, on
which the Pool Distribution Amount equals or exceeds the monthly premium for the
Insurance Policy, the Class A Interest Amount and the Distributable Unoffered
Class A-IO Interest Amount, distributions in respect of interest to each Class A
Subclass will equal its Class A Subclass Interest Amount, and distributions in
respect of interest to the Unoffered Class A-IO CitiCertificates will equal the
Distributable Unoffered Class A-IO Interest Amount.

     On each Distribution Date on or prior to the Accretion Termination Date, an
amount equal to the Class A Subclass Interest Amount for the Class A-6
CitiCertificates will not be distributed as interest to holders of the Class A-6
CitiCertificates but instead will be added to the Class A Subclass Stated Amount
of the Class A-6 CitiCertificates and distributed in reduction of the Stated
Amount of the Accretion Directed CitiCertificates on such Distribution Date.

     In the unlikely event that, on any Distribution Date prior to the
Subordination Depletion Date, the Pool Distribution Amount is less than the
monthly premium for the Insurance Policy, the Class A Interest Amount and the
Distributable Unoffered Class A-IO Interest Amount, the amount of interest
currently distributed on the Class A and Unoffered Class A-IO CitiCertificates
will equal the Pool Distribution Amount less the monthly premium for the
Insurance Policy and will be allocated among the Class A Subclasses and the
Unoffered Class A-IO CitiCertificates pro rata in accordance with the Class A
Subclass Interest Amounts and the Distributable Unoffered Class A-IO Interest
Amount, respectively. To the extent that such Class A Interest Shortfall Amount
is allocated to the Class A-11 CitiCertificates such amount will be covered by
the Insurance Policy as and to the extent described herein. Any Class A Subclass
Interest Shortfall Amount and Unoffered Class A-IO Unpaid Interest Shortfall
will be added to the amount to be distributed to the related Class A Subclass
and the Unoffered Class A-IO CitiCertificates, as applicable, on subsequent
Distribution Dates to the extent that the Pool Distribution Amount is sufficient
therefor and, in the case


                                      S-38

<PAGE>

of a Class A Subclass, the related Class A Subclass is then outstanding. No
interest will accrue on the unpaid Class A Subclass Interest Shortfall Amounts
or Unoffered Class A-IO Unpaid Interest Shortfall. See "SUMMARY OF PROSPECTUS
AND PROSPECTUS SUPPLEMENT--Priority of Distributions" herein.

     On each Distribution Date on which the Pool Distribution Amount exceeds the
monthly premium for the Insurance Policy, the Class A Interest Amount and the
Distributable Unoffered Class A-IO Interest Amount, any excess will then be
allocated first to pay previously unpaid Class A Subclass Interest Shortfall
Amounts of outstanding Class A Subclasses and the Unoffered Class A-IO Unpaid
Interest Shortfall. Such amounts will be allocated among the then outstanding
Class A Subclasses and the Unoffered Class A-IO CitiCertificates pro rata in
accordance with the respective unpaid Class A Subclass Interest Shortfall
Amounts and Unoffered Class A-IO Unpaid Interest Shortfall immediately prior to
such Distribution Date. Funds which become available to pay any Class A Subclass
Interest Shortfall Amount previously allocated to the Class A-6 CitiCertificates
will not be distributed (prior to the Accretion Termination Date) to the Class
A-6 CitiCertificates, but will instead be distributed first in reduction of the
Stated Amount of the Accretion Directed CitiCertificates and then in reduction
of the Stated Amount of the Class A-6 CitiCertificates as described below under
"--Distributions in Reduction of Stated Amount," and the Stated Amount of the
Class A-6 CitiCertificates will be increased by the amount of such reduction.
See "SUMMARY OF PROSPECTUS AND PROSPECTUS Supplement--Priority of Distributions"
herein.

     On each Distribution Date on which the Pool Distribution Amount equals or
exceeds the sum of (i) the Class M Interest Amount, (ii) all amounts
distributable on the Class A and Unoffered Class A-IO CitiCertificates and (iii)
the monthly premium for the Insurance Policy, distributions in respect of
interest to the Class M CitiCertificates will equal the Class M Interest Amount.

     If, on any Distribution Date, the Pool Distribution Amount is less than the
sum of (i) the Class M Interest Amount and (ii) all amounts senior in priority
of payment to such amount, the amount of interest currently distributed on the
Class M CitiCertificates will equal the Pool Distribution Amount, net of all
amounts distributable with a higher order of priority as provided above under
"SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions."
Any Class M Unpaid Interest Shortfall will be added to the amount to be
distributed to Class M CitiCertificates on subsequent Distribution Dates to the
extent that the Pool Distribution Amount is sufficient therefor and the related
Class M CitiCertificates are then outstanding. No interest will accrue on any
Class M Unpaid Interest Shortfall.

     On each Distribution Date on which the Pool Distribution Amount equals or
exceeds the sum of (i) the Offered Class B Subclass Interest Amount for an
Offered Class B Subclass and (ii) all amounts senior in priority of payment to
the Offered Class B Subclass Interest Amount based on the priorities described
under "SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of
Distributions," distributions in respect of interest to such Offered Class B
Subclass will equal its Offered Class B Subclass Interest Amount.

     If, on any Distribution Date, the Pool Distribution Amount is less than the
sum of (i) the Offered Class B Subclass Interest Amount for an Offered Class B
Subclass and (ii) all amounts senior in priority of payment to such amount, the
amount of interest currently distributed on such Offered Class B Subclass will
equal the Pool Distribution Amount, net of all amounts distributable with a
higher order of priority as provided above under "SUMMARY OF PROSPECTUS AND
PROSPECTUS SUPPLEMENT--Priority of Distributions." Any Offered Class B Subclass
Unpaid Interest Shortfall will be added to the amount to be distributed to such
Offered Class B Subclass on subsequent Distribution Dates to the extent that the
Pool Distribution Amount is sufficient therefor and the related Offered Class B
Subclass is then outstanding. No interest will accrue on any Offered Class B
Subclass Unpaid Interest Shortfall.

     If, on any Distribution Date, the Pool Distribution Amount is less than the
sum of the monthly premium on the Insurance Policy and all amounts distributable
on the Class A, Unoffered Class A-IO, Class M and Class B-1 CitiCertificates,
then the Class B-2 CitiCertificates and the Unoffered Class B CitiCertificates
will not be entitled to receive any amounts in respect of interest or principal.
If, on any Distribution Date, the Pool Distribution Amount is less than the sum
of the monthly premium on the Insurance Policy and all amounts distributable on
the Class A, Unoffered Class A-IO, Class M, Class B-1 and Class B-2
CitiCertificates, then the Unoffered Class B CitiCertificates will not be
entitled to receive any amounts in respect of interest or principal. If, on any
Distribution Date, the Pool Distribution Amount is less than the sum of the
monthly premium on the Insurance Policy and all amounts


                                      S-39

<PAGE>

distributable on the Class A and Unoffered Class A-IO CitiCertificates, then the
Class M and Class B CitiCertificates will not be entitled to receive any amounts
in respect of interest or principal.

DISTRIBUTIONS IN REDUCTION OF STATED AMOUNT

     The Mortgage Loans will be divided into two groups: the "Discount Mortgage
Loans," which will be comprised of all Mortgage Loans with Note Rates, net of
the Servicing Fee (in each case, the "NNR"), of less than 6.50% and the "Premium
Mortgage Loans," which will be comprised of all Mortgage Loans with NNRs equal
to or greater than 6.50%.

     Distributions in reduction of Stated Amount of the Class A CitiCertificates
(other than the interest-only Class A-12 CitiCertificates) will be made on each
Distribution Date in an aggregate amount equal to the Class A Principal
Distribution Amount. The "Class A Principal Distribution Amount" with respect to
any Distribution Date will be equal to the sum of (i) the amount of principal
distributed pursuant to clause (4) as set forth in the first paragraph under
"SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions" in
an amount up to the Class A Optimal Principal Amount and (ii) the Accretion
Distribution Amount, if any, with respect to such Distribution Date. The
"Accretion Distribution Amount" with respect to any Distribution Date will be
equal to the sum of (i) the Accretion Amount for such Distribution Date and (ii)
prior to the Accretion Termination Date, the portion of any payment with respect
to the Class A Unpaid Interest Shortfall allocated to the Class A-6
CitiCertificates on such Distribution Date. Amounts distributed in reduction of
Stated Amount of any Class A Subclass other than the Retail CitiCertificates
will be allocated pro rata among all CitiCertificates of such Class A Subclass.
Distributions in reduction of Stated Amount of the Retail CitiCertificates will
be made as described under "--Distributions in Reduction of Stated Amount of the
Retail CitiCertificates."

     The Class M CitiCertificates will be entitled to receive, on each
Distribution Date, an amount up to the Class M Optimal Distribution Amount for
each date, subject to the priorities and conditions set forth above under
"SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions."
The "Class M Optimal Distribution Amount" for each Distribution Date shall equal
the sum of (i) the Class M Interest Amount, (ii) the Class M Unpaid Interest
Shortfall and (iii) the Class M Optimal Principal Amount.

     The Class B CitiCertificates will be entitled, on each Distribution Date,
to the remaining portion, if any, of the applicable Pool Distribution Amount,
after payment of the monthly premium on the Insurance Policy, the Class A
Interest Amount, the Distributable Unoffered Class A-IO Interest Amount, any
unreimbursed Class A Unpaid Interest Shortfall, any unreimbursed Unoffered Class
A-IO Unpaid Interest Shortfall, the Class A Principal Distribution Amount, the
Class M Optimal Distribution Amount and (to the extent of Available PO Loss
Funds) any Unpaid PO Loss Amounts for such date. Amounts so distributed to Class
B CitiCertificateholders will not be available to cover delinquencies or
Realized Losses in respect of subsequent Distribution Dates.

     Holders of the CitiCertificates of each Offered Class B Subclass will be
entitled to receive, on each Distribution Date, an amount up to the Offered
Class B Subclass Optimal Distribution Amount for such Class B Subclass for such
date, subject to the priorities and conditions set forth above under "SUMMARY OF
PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions" in this
Prospectus Supplement. The "Offered Class B Subclass Optimal Distribution
Amount" for each Distribution Date for each Class B Subclass shall equal the sum
of (i) the Offered Class B Subclass Interest Amount for such Class B Subclass,
(ii) the Offered Class B Subclass Unpaid Interest Shortfall for such Class B
Subclass and (iii) the Offered Class B Subclass Optimal Principal Amount for
such Class B Subclass. The aggregate of the Offered Class B Subclass Optimal
Distribution Amounts is the "Offered Class B Optimal Distribution Amount."

     Holders of the Class A-14 CitiCertificates will be entitled to receive on
each Distribution Date, to the extent of the Pool Distribution Amount remaining
after payment of the monthly premium on the Insurance Policy, the Class A
Interest Amount, the Distributable Unoffered Class A-IO Interest Amount, any
unreimbursed Class A Unpaid Interest Shortfall and any unreimbursed Unoffered
Class A-IO Unpaid Interest Shortfall, a distribution in reduction of their
Stated Amount in an amount equal to the Class A PO Principal Amount. The "Class
A PO Principal Amount" with respect to each Distribution Date will be an amount
equal to the sum of (i) the applicable PO Percentage of (A) all scheduled
payments of principal due on each outstanding Mortgage Loan (including each
defaulted Mortgage Loan, other than a Liquidated Loan, with respect to which the
related Mortgaged Property has been acquired by the Trust) on the first day of
the month in which the Distribution Date occurs, less (B) if the Bankruptcy


                                      S-40

<PAGE>

Coverage Termination Date has occurred, the principal portion of Debt Service
Reductions, (ii) the applicable PO Percentage of the Adjusted Balance of each
Mortgage Loan which, during the month preceding the month of such Distribution
Date was repurchased by the Issuer, as described in "APPENDIX A: THE MORTGAGE
LOANS AND CITIMORTGAGECERTIFICATES--Assignment of Loans" in the Prospectus,
(iii) the applicable PO Percentage of the aggregate net Liquidation Proceeds on
all Mortgage Loans that became Liquidated Loans during such preceding month,
less the amounts allocable to principal of any unreimbursed advances previously
made by the Servicer or the Trustee with respect to such Liquidated Loans and
the portion of the net Liquidation Proceeds allocable to interest, (iv) the
applicable PO Percentage of the Adjusted Balance of each Mortgage Loan which was
the subject of a principal prepayment in full during the month preceding the
month of such Distribution Date and (v) the applicable PO Percentage of all
partial principal prepayments received by the Servicer in the month preceding
the month in which such Distribution Date occurs. In addition, holders of the
Class A-14 CitiCertificates will be entitled to reimbursement, to the extent of
Available PO Loss Funds, of the "Unpaid PO Loss Amounts," which shall equal the
difference between (a) the sum of the PO Loss Amounts for that and prior
Distribution Dates and (b) amounts distributed in reimbursement of Unpaid PO
Loss Amounts on all prior Distribution Dates.

     Holders of the Class A CitiCertificates (other than the Class A-14
CitiCertificates) will be entitled to receive on each Distribution Date, to the
extent of the Pool Distribution Amount remaining after payment of the monthly
premium on the Insurance Policy, the Class A Interest Amount, the Distributable
Unoffered Class A-IO Interest Amount and any unreimbursed Class A and Unoffered
Class A-IO Unpaid Interest Shortfalls, a distribution in reduction of the Stated
Amount thereof in an amount equal to the Class A Non-PO Principal Amount. The
"Class A Non-PO Principal Amount" with respect to each Distribution Date will be
an amount equal to the sum of (i) the Class A Percentage of the applicable
Non-PO Percentage of (A) all scheduled payments of principal due on each
outstanding Mortgage Loan (including each defaulted Mortgage Loan, other than a
Liquidated Loan, with respect to which the related Mortgaged Property has been
acquired by the Trust) on the first day of the month in which the Distribution
Date occurs, less (B) if the Bankruptcy Coverage Termination Date has occurred,
the principal portion of Debt Service Reductions, (ii) the Class A Prepayment
Percentage of the applicable Non-PO Percentage of the Adjusted Balance of each
Mortgage Loan which, during the month preceding the month of such Distribution
Date was repurchased by the Issuer, as described in "APPENDIX A: THE MORTGAGE
LOANS AND CITIMORTGAGE CERTIFICATES--Assignment of Loans" in the Prospectus,
(iii) the Class A Prepayment Percentage of the applicable Non-PO Percentage of
the aggregate net Liquidation Proceeds on all Mortgage Loans that became
Liquidated Loans during such preceding month, less the amounts allocable to
principal of any unreimbursed advances previously made by the Servicer or the
Trustee with respect to such Liquidated Loans and the portion of the net
Liquidation Proceeds allocable to interest, (iv) the Class A Prepayment
Percentage of the applicable Non-PO Percentage of the Adjusted Balance of each
Mortgage Loan which was the subject of a principal prepayment in full during the
month preceding the month of such Distribution Date and (v) the Class A
Prepayment Percentage of the applicable Non-PO Percentage of all partial
principal prepayments received by the Servicer in the month preceding the month
in which such Distribution Date occurs.

     The "Class A Optimal Principal Amount" with respect to each Distribution
Date will be equal to the sum of the Class A PO Principal Amount and the Class A
Non-PO Principal Amount with respect to such Distribution Date. With respect to
each Discount Mortgage Loan, the "PO Percentage" is equal to a fraction,
expressed as a percentage, the numerator of which is 6.50% minus the NNR of such
Mortgage Loan and the denominator of which is 6.50%; with respect to each
Premium Mortgage Loan, the PO Percentage is 0%. With respect to each Mortgage
Loan, the "Non-PO Percentage" is equal to 100% minus the related PO Percentage;
therefore, for each Premium Mortgage Loan the Non-PO Percentage is 100%.

     On each Distribution Date on or prior to the Accretion Termination Date,
that portion of the Class A Principal Distribution Amount that represents the
Accretion Distribution Amount will be allocated first to the Class A-3
CitiCertificates, the Class A-4 CitiCertificate (Component 1) and the Class A-5
CitiCertificate (Component 1) pro rata up to the amount necessary to reduce the
Stated Amount of the Class A-3 CitiCertificates and the Component Stated Amounts
of such Components to their respective Targeted Balances for such Distribution
Date, second to the Class A-4 CitiCertificate (Component 2) and the Class A-5
CitiCertificate (Component 2) pro rata until the Component Stated Amounts
thereof have been reduced to zero, third to the Class A-3 CitiCertificates, the
Class A-4 CitiCertificate (Component 1) and the Class A-5 CitiCertificate
(Component 1) pro rata without regard to their respective Targeted Balances
until the Stated Amount of the Class A-3 CitiCertificates and the Component
Stated

Amounts of such Components have been reduced to zero and fourth to the Class A-6
CitiCertificates until the Stated Amount thereof has been reduced to zero.

     On each Distribution Date prior to the Subordination Depletion Date, the
Class A Principal Distribution Amount (other than the portion that represents
the Accretion Distribution Amount, which will be distributed as provided in the
preceding paragraph), will be allocated among and distributed in reduction of
the Stated Amount of the Class A Subclasses on each Distribution Date
sequentially as follows:

          I. The Class A PO Principal Amount for such Distribution Date will be
     allocated to the Class A-14 CitiCertificates until the Stated Amount

     The "Scheduled Principal Amount" means the sum for each outstanding
Mortgage Loan (including each defaulted Mortgage Loan, other than a Liquidated
Loan, with respect to which the related Mortgaged Property has been acquired by
the Trust) of the product of (A) the Non-PO Percentage for such Mortgage Loan

been acquired by the Trust) on the first day of the month in which the
Distribution Date occurs, less (B) if the Bankruptcy Coverage Termination Date
has occurred, the principal portion of Debt Service Reductions, (ii) the Class M
Prepayment Percentage of the applicable Non-PO Percentage of the Adjusted
Balance of each Mortgage Loan which, during the month preceding the month of
such Distribution Date, was repurchased by the Issuer, as described in "APPENDIX
A: THE MORTGAGE LOANS AND CITIMORTGAGE CERTIFICATES--Assignment of Loans" in the
Prospectus, (iii) the Class M Prepayment Percentage of the applicable Non-PO
Percentage of the aggregate net Liquidation Proceeds on all Mortgage Loans that
became Liquidated Loans during such preceding month, less the amounts allocable
to principal of any unreimbursed advances previously made by the Servicer or the
Trustee with respect to such Liquidated Loans and the portion of the net
Liquidation Proceeds allocable to interest, (iv) the Class M Prepayment
Percentage of the applicable Non-PO Percentage of the Adjusted Balance of each
Mortgage Loan which was the subject of a principal prepayment in full during the
month preceding the month of such Distribution Date and (v) the Class M
Prepayment Percentage of the applicable Non-PO Percentage of all partial
principal prepayments received by the Servicer in the month preceding the month
in which such Distribution Date occurs.

     The "Offered Class B Subclass Optimal Principal Amount" with respect to
each Distribution Date for a particular Class B Subclass will be an amount equal
to the sum of (i) the Offered Class B Subclass Percentage for such Class B
Subclass of the applicable Non-PO Percentage of (A) all scheduled payments of
principal due on each outstanding Mortgage Loan (including each defaulted
Mortgage Loan, other than a Liquidated Loan, with respect to which the related
Mortgaged Property has been acquired by the Trust) on the first day of the month
in which the Distribution Date occurs, less (B) if the Bankruptcy Coverage
Termination Date has occurred, the principal portion of Debt Service Reductions,
(ii) the Offered Class B Subclass Prepayment Percentage for such Offered Class B
Subclass of the applicable Non-PO Percentage of the Adjusted Balance of each
Mortgage Loan which, during the month preceding the month of such Distribution
Date was repurchased by the Issuer, (iii) the Offered Class B Subclass
Prepayment Percentage for such Offered Class B Subclass of the applicable Non-PO
Percentage of the aggregate net Liquidation Proceeds on all Mortgage Loans that
became Liquidated Loans during such preceding month, less the amounts allocable
to principal of any unreimbursed advances previously made by the Servicer or the
Trustee with respect to such Liquidated Loans and the portion of the net
Liquidation Proceeds allocated to interest, (iv) the Offered Class B Subclass
Prepayment Percentage for such Offered Class B Subclass of the applicable Non-PO
Percentage of the Adjusted Balance of each Mortgage Loan which was the subject
of a principal prepayment in full during the month preceding the month of such
Distribution Date and (v) the Offered Class B Subclass Prepayment Percentage for
such Offered Class B Subclass of the applicable Non-PO Percentage of all partial
principal prepayments received by the Servicer in the month preceding the month
in which such Distribution Date occurs.

     In addition to the foregoing, in the event that there is any recovery of an
amount in respect of principal which had previously been allocated as a Realized
Loss, the amount of such recovery will be allocated among the then outstanding
CitiCertificates first to the Class A CitiCertificates, to the extent, in the
manner and up to the amount of any unreimbursed Realized Losses allocated to the
Class A CitiCertificates, then to the Class M CitiCertificates and then to the
Class B CitiCertificates. As among the Class B Subclasses, the amount of the
recovery remaining after any allocation thereof to the Class A and Class M
CitiCertificates will be allocated first to the Class B-1 CitiCertificates,
second to the Class B-2 CitiCertificates, in each case to the extent and up to
the amount of any unreimbursed Realized Losses allocated to such Class B
Subclass, and then, in like manner, to the remaining Class B Subclasses.

     A "Liquidated Loan" is a Mortgage Loan with respect to which the Servicer
has determined that all recoverable liquidation and insurance proceeds have been
received or the Issuer has accepted payment by a Mortgagor in consideration for
the release of the Mortgage in an amount equal to less than the outstanding
principal balance of the Mortgage Loan as a result of a determination that
liquidation expenses for such Mortgage Loan would exceed the amount by which the
cash portion of such payment is less than the outstanding principal balance of
such Mortgage Loan.

     A "Liquidated Loan Loss" on a Liquidated Loan is equal to the excess, if
any, of (i) the unpaid principal balance of such Liquidated Loan, plus interest
thereon in accordance with the amortization schedule at the Note Rate through


                                      S-44

<PAGE>

the last day of the month in which such Mortgage Loan was liquidated, over (ii)
net Liquidation Proceeds. For purposes of calculating the amount of any
Liquidated Loan Loss, all net Liquidation Proceeds (after reimbursement to the
Servicer and the Trustee for any previously unreimbursed related advances and
related liquidation expenses) will be applied first to accrued interest and then
to the unpaid principal balance of the Liquidated Loan. "Liquidation Proceeds"
are all amounts received by the Servicer in connection with the liquidation of
defaulted Mortgage Loans or property acquired in respect thereof. A "Special
Hazard Loss" is a Liquidated Loan Loss occurring as a result of a Special
Hazard. "Special Hazards" are all risks of direct physical loss or damage which
occur from any cause excluding (a) the extraordinary events referred to in the
last paragraph under "--Subordination--Allocation of Losses" and (b) any risk of
direct physical loss or damage that is insured against under either (i) the
Mortgagor's homeowner's policy, fire insurance policy, flood insurance (if
otherwise required) and extended coverage policies (if any), as required to be
maintained pursuant to the applicable Mortgage Loan or (ii) hazard insurance
with respect to such Mortgaged Property which is required to be maintained by
the Servicer under the Pooling Agreement. A "Fraud Loss" is a Liquidated Loan
Loss incurred on a Liquidated Loan as to which there was fraud in the
origination of such Mortgage Loan. A "Bankruptcy Loss" is a loss attributable to
certain actions which may be taken by a bankruptcy court in connection with a
Mortgage Loan, including a reduction by a bankruptcy court of the principal
balance of or the interest rate on a Mortgage Loan or an extension of its
maturity. A "Debt Service Reduction" means a reduction in the amount of monthly
payments due to certain bankruptcy proceedings, but does not include any
permanent forgiveness of principal. A "Deficient Valuation" with respect to a
Mortgage Loan means a valuation by a court of the Mortgaged Property in an
amount less than the outstanding indebtedness under the Mortgage Loan or any
reduction in the amount of monthly payments that result in a permanent
forgiveness of principal, which valuation or reduction results from a bankruptcy
proceeding. Liquidated Loan Losses (including Special Hazard Losses and Fraud
Losses) and Bankruptcy Losses are referred to herein as "Realized Losses."

     The "Class A Percentage" for any Distribution Date occurring prior to the
Subordination Depletion Date is the percentage, which in no event will exceed
100%, obtained by dividing the Class A Stated Amount (after subtracting the
Stated Amount of the Class A-14 CitiCertificates) by the Non-PO Pool Adjusted
Balance, both as of the immediately preceding Distribution Date (after taking
into account distributions in reduction of Stated Amount and the allocation of
any losses on such date). The Class A Percentage for the first Distribution Date
is expected to be between 94.75% and 96.75%. The Class A Percentage will
decrease as a result of the allocation of certain unscheduled payments in
respect of principal according to the Class A Prepayment Percentage for a
specified period to the Class A CitiCertificates and will increase as a result
of the allocation of Realized Losses to the Subordinated CitiCertificates.

     The "Class A Prepayment Percentage" for any Distribution Date occurring
during the five years beginning on the first Distribution Date will, except as
provided below, equal 100%. Thereafter, the Class A Prepayment Percentage will
be subject to gradual reduction as described in the following paragraph. This
disproportionate allocation of certain unscheduled payments in respect of
principal will have the effect of accelerating the amortization of the Class A
CitiCertificates (other than the Class A-13 and Class A-14 CitiCertificates)
while, in the absence of Realized Losses, increasing the respective interest in
the Trust evidenced by the Class M and Class B CitiCertificates. Increasing the
respective interest of the Class M and Class B CitiCertificates relative to that
of the Class A CitiCertificates is intended to preserve the availability of the
subordination provided by the Class M and Class B CitiCertificates. See
"--Subordination" below.

     The Class A Prepayment Percentage for any Distribution Date occurring
during the periods set forth below will be as follows:

PERIOD (DATES INCLUSIVE)                 CLASS A PREPAYMENT PERCENTAGE
- ------------------------                 -----------------------------

August 2003-July 2004 ............   Class A Percentage plus 70% of the
                                      Subordinated CitiCertificate Percentage

August 2004-July 2005 ............   Class A Percentage plus 60% of the
                                      Subordinated CitiCertificate Percentage

August 2005-July 2006 ............   Class A Percentage plus 40% of the
                                      Subordinated CitiCertificate Percentage

August 2006-July 2007 ............   Class A Percentage plus 20% of the
                                      Subordinated CitiCertificate Percentage

August 2007 and thereafter .......   Class A Percentage


                                      S-45

<PAGE>

     Notwithstanding the foregoing, if the Class A Percentage on any
Distribution Date exceeds the initial Class A Percentage, the Class A Prepayment
Percentage for such Distribution Date will once again equal 100%. See
"--Prepayment and Yield Considerations" herein and "PREPAYMENT AND YIELD
CONSIDERATIONS" in the Prospectus.

     In addition, no reduction of the Class A Prepayment Percentage will occur
on a Distribution Date unless the following tests are satisfied: (i) as of the
first Distribution Date as to which any such reduction applies, either (A) the
Adjusted Balance of the Mortgage Loans delinquent 60 days or more (including,
for this purpose, Mortgage Loans in foreclosure and real estate owned by the
Trust as a result of Mortgagor default) averaged over the last six months, as a
percentage of the sum of the Class M Stated Amount and the Class B Stated Amount
averaged over the last six months, is less than 50% or (B) the Adjusted Balance
of such delinquent Mortgage Loans averaged over such period, as a percentage of
the Adjusted Balance of all Mortgage Loans averaged over such period, is less
than 2%, and (ii) cumulative Realized Losses with respect to the Mortgage Loans
are less than (a) with respect to each Distribution Date in August 2003 through
July 2004, inclusive, 30% of the aggregate Initial Stated Amount of the Class M
and Class B CitiCertificates (the "Original Subordinated Stated Amount"), (b)
with respect to each Distribution Date in August 2004 through July 2005,
inclusive, 35% of the Original Subordinated Stated Amount, (c) with respect to
each Distribution Date in August 2005 through July 2006, inclusive, 40% of the
Original Subordinated Stated Amount, (d) with respect to each Distribution Date
in August 2006 through July 2007, inclusive, 45% of the Original Subordinated
Stated Amount, and (e) with respect to each Distribution Date in August 2007 and
thereafter, 50% of the Original Subordinated Stated Amount.

     The "Subordinated CitiCertificate Percentage" for any Distribution Date
will be calculated as the difference between 100% and the Class A Percentage for
such date. The Subordinated CitiCertificate Percentage on the Closing Date is
expected to be between 3.25% and 5.25%.

     The "Subordinated Prepayment Percentage" for any Distribution Date will be
calculated as the difference between 100% and the Class A Prepayment Percentage
for each date.

     The "Class M Percentage" shall be equal to the percentage calculated by
multiplying (i) the Subordinated CitiCertificate Percentage by (ii) a fraction,
the numerator of which is the Class M Stated Amount and the denominator of which
is the sum of the Class M Stated Amount and the Class B Subclass Stated Amount
of each Class B Subclass eligible to receive distributions in reduction of
Stated Amount, each as of the immediately preceding Distribution Date (after
taking into account distributions in reduction of Stated Amount and the
allocation of losses on such date).

     The "Class M Prepayment Percentage" shall be equal to the percentage
calculated by multiplying (i) the Subordinated Prepayment Percentage by (ii) a
fraction, the numerator of which is the Class M Stated Amount and the
denominator of which is the sum of the Class M Stated Amount and the Class B
Subclass Stated Amount of each Class B Subclass eligible to receive
distributions in reduction of Stated Amount, each as of the immediately
preceding Distribution Date (after taking into account distributions in
reduction of Stated Amount and the allocation of losses on such date).

     The "Class B Percentage" for any Distribution Date will be calculated as
the difference between the Subordinated CitiCertificate Percentage and the Class
M Percentage.

     The "Class B Prepayment Percentage" for any Distribution Date will be
calculated as the difference between the Subordinated Prepayment Percentage and
the Class M Prepayment Percentage.

     The "Offered Class B Subclass Percentage" for each Offered Class B Subclass
shall be equal to, on any Distribution Date, the percentage calculated by
multiplying (i) the Class B Percentage by (ii) a fraction, the numerator of
which is the Offered Class B Subclass Stated Amount of such Offered Class B
Subclass and the denominator of which is the aggregate Stated Amounts of the
Class B Subclasses (eligible to receive distributions in reduction of Stated
Amount for such Distribution Date), each as of the immediately preceding
Distribution Date (after taking into account distributions in reduction of
Stated Amount and the allocation of any losses on such date); provided that in
the event a particular Offered Class B Subclass is ineligible to receive
distributions in reduction of Stated Amount on such Distribution Date, its
Offered Class B Subclass Percentage will be 0% for such Distribution Date.


                                      S-46

<PAGE>

     The "Offered Class B Subclass Prepayment Percentage" for each Offered Class
B Subclass shall be equal to, on any Distribution Date, the percentage
calculated by multiplying (i) the Class B Prepayment Percentage by (ii) a
fraction, the numerator of which is the Stated Amount of such Offered Class B
Subclass and the denominator of which is the aggregate Stated Amounts of the
Class B Subclasses (eligible to receive distributions in reduction of Stated
Amount for such Distribution Date), each as of the immediately preceding
Distribution Date (after taking into account distribution in reduction of Stated
Amount and the allocation of any losses on such date); provided that in the
event an Offered Class B Subclass is ineligible to receive distributions in
reduction of Stated Amount on such Distribution Date, such Offered Class B
Subclass Prepayment Percentage will be 0% for such Distribution Date.

     In the event that on any Distribution Date, the Current Class M
Subordination Level is less than the original Class M Subordination Level, then
the Class B CitiCertificates will not be entitled to any distributions in
reduction of Stated Amount on such Distribution Date and all of such
distributions will instead be allocated in reduction of the Stated Amount of the
Class M CitiCertificates. The original Class M Subordination Level is expected
to be between 1.25% and 3.25%.

     In the event that on any Distribution Date, the Current Class M
Subordination Level equals or exceeds its original percentage but the Current
Class B-1 Subordination Level is less than the original Class B-1 Subordination
Level, then the Class B-2, Class B-3, Class B-4 and Class B-5 CitiCertificates
will not be entitled to any distributions in reduction of Stated Amount on such
Distribution Date and all of such distributions will instead be allocated in
reduction of the Stated Amount of the Class M and Class B-1 CitiCertificates.
The original Class B-1 Subordination Level is expected to be between 0.80% and
1.80%.

     In the event that on any Distribution Date, the Current Class M and Class
B-1 Subordination Levels equal or exceed their original percentages but the
Current Class B-2 Subordination Level is less than the original Class B-2
Subordination Level, then the Class B-3, Class B-4 and Class B-5
CitiCertificates will not be entitled to any distributions in reduction of
Stated Amount on such Distribution Date, and all of such distributions will
instead be allocated in reduction of the Stated Amounts of the Class M, Class
B-1 and Class B-2 CitiCertificates. The original Class B-2 Subordination Level
is expected to be between 0.65% and 1.05%.

     In the event that on any Distribution Date, the Current Class M, Class B-1
and Class B-2 Subordination Levels equal or exceed their original percentages
but the Current Class B-3 Subordination Level is less than the original Class
B-3 Subordination Level, then the Class B-4 and Class B-5 CitiCertificates will
not be entitled to any distributions in reduction of Stated Amount on such
Distribution Date, and all of such distributions will instead be allocated in
reduction of the Stated Amounts of the Class M, Class B-1, Class B-2 and Class
B-3 CitiCertificates. The original Class B-3 Subordination Level is expected to
be between 0.30% and 0.70%.

     In the event that on any Distribution Date, the Current Class M, Class B-1,
Class B-2 and Class B-3 Subordination Levels equal or exceed their original
percentages but the Current Class B-4 Subordination Level is less than the
original Class B-4 Subordination Level, then the Class B-5 CitiCertificates will
not be entitled to any distributions in reduction of Stated Amount on such
Distribution Date, and all of such distributions will instead be allocated in
reduction of the Stated Amounts of the Class M, Class B-1, Class B-2, Class B-3
and Class B-4 CitiCertificates. The original Class B-4 Subordination Level is
expected to be between 0.10% and 0.50%.

     On any Distribution Date on which the Stated Amounts of the Class M and
Class B CitiCertificates have been reduced to zero, the Class A Non-PO Principal
Amount will be distributed pro rata to each Class A Subclass (other than the
Class A-14 CitiCertificates) notwithstanding the priorities described above.
Under the circumstances described in this paragraph, the amount allocated to
each such Class A Subclass will be distributed pro rata among holders of
CitiCertificates of such Class A Subclass.

  The PAC Certificates

     On each Distribution Date, the Class A Principal Distribution Amount will
be allocated among the Class A Subclasses as described under "--Distributions in
Reduction of Stated Amount". To the extent that funds are available to make
distributions in reduction of the Stated Amounts of the PAC Certificates on each
Distribution Date, the PAC Certificates will be entitled to receive their PAC
Balance Amounts, if any, for such Distribution Date as determined by reference
to the Planned Balances set forth in the table below.


                                      S-47

<PAGE>

     The Planned Balances for each Class A Subclass of the PAC Certificates on
each Distribution Date were calculated assuming that: (i) the Mortgage Loans and
the CitiCertificates have the characteristics of the actual Mortgage Loans
expected to be included in the Trust as described under "DESCRIPTION OF THE POOL
AND THE MORTGAGED PROPERTIES," (ii) the CitiCertificates have the
characteristics set forth in the Structuring Assumptions described under the
heading "--Weighted Average Lives of the Offered CitiCertificates," and (iii)
the Mortgage Loans are prepaid at any constant rate within the range of 100% to
400% of the Prepayment Model.

     It is extremely unlikely that the Mortgage Loans will prepay at a constant
percentage of the Prepayment Model. In addition, some or all of the other
assumptions stated above that are used in preparing the following table are
unlikely to reflect actual experience. Accordingly, there is no assurance that
the Stated Amount of a Class A Subclass of the PAC Certificates will conform on
any Distribution Date to the applicable level set forth in such table. In
addition, if the portion of the Class A Non-PO Principal Amount available to
make distributions in reduction of the Stated Amounts of the PAC Certificates
exceeds the amount necessary to pay the PAC Balance Amounts for the PAC
Certificates on any Distribution Date, the excess will be allocated on such
Distribution Date to distributions in reduction of Stated Amount of the
CitiCertificates in accordance with the priorities described herein, and will
not be retained for distribution on subsequent Distribution Dates. See
"--Distributions in Reduction of Stated Amount" above. Accordingly, if principal
prepayments on the Mortgage Loans do not occur at a constant rate within the
range specified in the preceding paragraph, the amount available on subsequent
Distribution Dates for payment of the PAC Certificates may be less than the PAC
Balance Amounts for such Distribution Dates, even if on average prepayments on
the Mortgage Loans do occur at such a constant rate. Distributions in reduction
of Stated Amount of a Class A Subclass of the PAC Certificates may reduce the
Stated Amount of such CitiCertificates to zero significantly earlier or later
than the Distribution Date specified herein. See "--Weighted Average Lives of
the Offered CitiCertificates" below for a further discussion of the effect of
prepayments on the Mortgage Loans on the rate of distributions in reduction of
Stated Amount and on the weighted average lives of the CitiCertificates.

  The TAC Certificates and TAC Components

     On each Distribution Date, the Class A Principal Distribution Amount will
be allocated among the Class A Subclasses as described above under
"--Distributions in Reduction of Stated Amount." To the extent that funds are
available to make distributions in reduction of the Stated Amount of the TAC
Certificates and the Component Stated Amounts of the TAC Components on each
Distribution Date, the TAC Certificates and TAC Components will be entitled to
receive their TAC Balance Amounts, if any, for such Distribution Date as
determined by reference to the Targeted Balances set forth in the table below.

     The Targeted Balances for the TAC Certificates and the TAC Components on
each Distribution Date were calculated assuming that: (i) the Mortgage Loans and
the CitiCertificates have the characteristics of the actual Mortgage Loans
expected to be included in the Trust as described under "DESCRIPTION OF THE POOL
AND THE MORTGAGED PROPERTIES," (ii) the CitiCertificates have the
characteristics set forth in the Structuring Assumptions described under the
heading "--Weighted Average Lives of the Offered CitiCertificates," and (iii)
the Mortgage Loans are prepaid at a constant rate equal to 125% of the
Prepayment Model.

     It is extremely unlikely that the Mortgage Loans will prepay at a constant
percentage of the Prepayment Model. In addition, some or all of the other
assumptions stated above that are used in preparing the following table are
unlikely to reflect actual experience. Accordingly, there is no assurance that
the Stated Amount of the TAC Certificates or the Component Stated Amounts of the
TAC Components will conform on any Distribution Date to the applicable level set
forth in such table. In addition, if the portion of the Class A Non-PO Principal
Amount available to make distributions in reduction of Stated Amount of the TAC
Certificates and the Component Stated Amounts of the TAC Components plus the
Accretion Distribution Amount for such Distribution Date exceeds the amount
necessary to pay the TAC Balance Amounts for the TAC Certificates on any
Distribution Date, the excess will be allocated on such Distribution Date to
distributions in reduction of Stated Amount of the CitiCertificates in
accordance with the priorities described herein, and will not be retained for
distribution on subsequent Distribution Dates. See "--Distributions in Reduction
of Stated Amount" above. Accordingly, if principal prepayments on the Mortgage
Loans do not occur at a constant 125% of the Prepayment Model, the amount
available on subsequent Distribution Dates for payment of the TAC Certificates
and TAC Components may be less than the TAC Balance Amounts for such
Distribution Dates, even if on average prepayments on the Mortgage Loans do
occur at 125% of the Prepayment Model. Distributions in reduction of Stated
Amount of the TAC Certificates and Component Stated Amounts of the TAC
Components may reduce the Stated Amount and Component Stated Amounts of such
CitiCertificates and Components to zero significantly earlier or later than the
Distribution Date specified herein. See "--Weighted Average Lives of the Offered
CitiCertificates" below for a further discussion of the effect of prepayments on
the Mortgage Loans on the rate of distributions in reduction of Stated Amount
and on the weighted average lives of the CitiCertificates.

DISTRIBUTIONS IN REDUCTION OF STATED AMOUNT OF THE RETAIL CITICERTIFICATES

  General

     Subject to the priorities and limitations described herein, Beneficial
Owners of the Retail CitiCertificates have the right to request that
distributions in reduction of Stated Amount be made with respect to their Retail
CitiCertificates on each Distribution Date on which distributions in reduction
of Stated Amount are made with respect to the Retail CitiCertificates. All such
distributions are subject to the limitations that they are made (i) only in lots
equal to $1,000 of Initial Stated Amount (each an "Individual Retail
CitiCertificate") and (ii) only to the extent that the portion of the Class A
Principal Distribution Amount allocated to the Retail CitiCertificates and any
Insured Payment applied in reduction of the Stated Amount of the Retail
CitiCertificates on the applicable Distribution Date (plus any amounts available
from the Retail Cash Deposit) provides sufficient funds for such requested
distributions. Interest will accrue on all Retail CitiCertificates with respect
to which distributions are made through the last day of the month preceding the
month in which such distributions are made.


                                      S-52







<PAGE>

     Notwithstanding any provisions to the contrary, if the Insurer fails to
make an Insured Payment or on any Distribution Date on and after the
Subordination Depletion Date, distributions in reduction of Stated Amount of the
Retail CitiCertificates will be made pro rata among the holders of the Retail
CitiCertificates and shall no longer be required to be made in integral
multiples of $1,000 or pursuant to requested distributions or mandatory
distributions by random lot. In the event that such pro rata distributions
cannot be made through the facilities of DTC, the Retail CitiCertificates will
be withdrawn from the facilities of DTC and Definitive Certificates will be
issued to replace such withdrawn Book-Entry CitiCertificates.

     There is no assurance that a Beneficial Owner who has submitted a request
for such distribution will receive such distribution within a reasonable period
of time after such distribution is requested. There can be no assurance that
funds will be available for making such distributions on any particular
Distribution Date, or, even if funds are available for making such distributions
in reduction of Stated Amount of the Retail CitiCertificates, that such
distributions with respect to the Retail CitiCertificates owned by any
particular Beneficial Owner will be made. See "--Weighted Average Lives of the
Class A CitiCertificates" herein.

  Priority of Requested Distributions

     Subject to the limitations described herein, Beneficial Owners of Retail
CitiCertificates have the right to request that distributions be made in
reduction of the Stated Amount of their Retail CitiCertificates. On each
Distribution Date on which distributions in reduction of Stated Amount are made
on the Retail CitiCertificates, such distributions will be made in the following
order of priority:

          (1) with respect to a Deceased Holder(1), any request by the personal
     representatives or by a surviving tenant by the entirety, by a surviving
     joint tenant or by a surviving tenant in common, but not exceeding an
     aggregate Stated Amount of $100,000 per request; and

          (2) with respect to a Beneficial Owner other than a Deceased Holder,
     any request not exceeding an aggregate Stated Amount of $10,000.

          Thereafter, requests for distributions in reduction of Stated Amount
     will be honored with respect to a Deceased Holder as provided in (1) above
     up to a second $100,000, and requests for such distributions will be
     honored with respect to a Beneficial Owner other than a Deceased Holder as
     provided in (2) above up to a second $10,000. This sequence of priorities
     will be repeated until all requests for distribution in reduction of Stated
     Amount have been honored.

- ----------

(1)  A "Deceased Holder" is a Beneficial Owner of a Retail CitiCertificate who
     was living at the time such interest was acquired and whose executor or
     other authorized representative causes to be furnished to DTC evidence of
     death satisfactory to the Trustee and any tax waivers requested by the
     Trustee. Retail CitiCertificates beneficially owned by tenants by the
     entirety, joint tenants or tenants in common will be considered to be
     beneficially owned by a single owner. The death of a tenant by the
     entirety, joint tenant or tenant in common will be deemed to be the death
     of the Beneficial Owner, and the Retail CitiCertificates so beneficially
     owned will be eligible for priority with respect to distributions in
     reduction of Stated Amount, subject to the limitations stated above. Retail
     CitiCertificates beneficially owned by a trust will be considered to be
     beneficially owned by each beneficiary of the trust to the extent of such
     beneficiary's beneficial interest therein, but in no event will a trust's
     beneficiaries collectively be deemed to be Beneficial Owners of a number of
     Individual Retail CitiCertificates greater than the number of Individual
     Retail CitiCertificates of which such trust is the owner. The death of a
     beneficiary of a trust will be deemed to be the death of a Beneficial Owner
     of the Retail CitiCertificates beneficially owned by the trust to the
     extent of such beneficiary's beneficial interest in such trust. The death
     of an individual who was a tenant by the entirety, joint tenant or tenant
     in common in a tenancy which is the beneficiary of a trust will be deemed
     to be the death of the beneficiary of the trust. The death of a person who,
     during his or her lifetime, was entitled to substantially all of the
     beneficial ownership interests in Retail CitiCertificates will be deemed to
     be the death of the Beneficial Owner of such Retail CitiCertificates
     regardless of the registration of ownership, if such beneficial interest
     can be established to the satisfaction of the Trustee. Such beneficial
     interest will be deemed to exist in typical cases of street name or nominee
     ownership, ownership by a trustee, ownership under the Uniform Gifts to
     Minors Act and community property or other joint ownership arrangements
     between a husband and wife. Beneficial interests shall include the power to
     sell, transfer or otherwise dispose of a Retail CitiCertificate and the
     right to receive the proceeds therefrom, as well as interest and
     distributions in reduction of Stated Amount payable with respect thereto.


                                      S-53

  Procedure for Requested Distributions

     A Beneficial Owner of a Retail CitiCertificate may request that
distributions in reduction of Stated Amount thereof be made on a Distribution
Date by delivering a written request therefor, together with appropriate
evidence of death and any necessary tax waivers in the case of a request by a
Deceased Holder, to the Participant or Indirect Participant that maintains its
account in the Retail CitiCertificates such that the request for such
distribution is received by the Trustee on or before the last day of the month
preceding the month in which such Distribution Date occurs. That firm should in
turn make the request of DTC (or, in the case of an Indirect Participant, such
firm must notify the related Participant of such request, which Participant
should make the request of DTC) in the manner required under the rules and
regulations of DTC's APUT system and provided to the Participant. This procedure
is further discussed below under the heading "--Book-Entry Registration." Upon
receipt of such request, DTC will date and time stamp such request and forward
such request to the Trustee. DTC may establish such procedures as it deems fair
and equitable to establish the order of receipt of requests for such
distributions received by it on the same day. Neither the Servicer nor the
Trustee shall be liable for any delay by DTC, any Participant or any Indirect
Participant in the delivery of requests for distributions to the Trustee. The
Servicer will instruct the Trustee that requests for distributions are to be
honored in the order of their receipt (subject to the priorities described
above). The exact procedures to be followed by the Trustee for purposes of
determining the order of receipt of such requests will be those established from
time to time by the Trustee, acting in conjunction with DTC. Requests for
distributions in reduction of Stated Amount received by DTC and forwarded to the
Trustee after the last day of the month preceding the month in which a
Distribution Date occurs and requests for distributions received in a timely
manner but not accepted with respect to a given Distribution Date, will be
treated as requests for distributions on the next succeeding Distribution Date
and each succeeding Distribution Date thereafter until each request is accepted
or is withdrawn as described below. Each request for distributions in reduction
of Stated Amount of a Retail CitiCertificate submitted by a Beneficial Owner
will be held by the Trustee until such request has been accepted or has been
withdrawn in writing. Each Individual Retail CitiCertificate covered by such
request will continue to bear interest at the related Stated Rate through the
last day of the month preceding the month in which such Distribution Date
occurs.

     With respect to Retail CitiCertificates as to which Beneficial Owners have
requested distributions on a particular Distribution Date on which distributions
in reduction of Stated Amount of the Retail CitiCertificates are being made, DTC
and its Participants will be notified prior to such Distribution Date whether,
and the extent to which, such Retail CitiCertificates have been accepted for
distributions. Participants and Indirect Participants holding Retail
CitiCertificates are required to notify the Beneficial Owners of such
CitiCertificates. It is expected that Beneficial Owners will receive such notice
no later than 3 days prior to the applicable Distribution Date. Individual
Retail CitiCertificates which have been accepted for a distribution shall be due
and payable on the applicable Distribution Date and shall cease to bear interest
after the last day of the month preceding the month in which such Distribution
Date occurs.

     Any Beneficial Owner of a Retail CitiCertificate which has requested a
distribution may withdraw its request by so notifying in writing the Participant
or Indirect Participant that maintains such Beneficial Owner's account. In the
event that such account is maintained by an Indirect Participant, such Indirect
Participant must notify the related Participant which in turn must forward the
withdrawal of such request, in the manner required under the rules and
regulations of DTC's APUT system. If such notice of withdrawal of a request for
distribution has not been received by the Trustee on or before the last day of
the month preceding the month in which a Distribution Date occurs, the
previously made request for distribution will be irrevocable with respect to the
making of distributions in reduction of Stated Amount of Retail CitiCertificates
on the applicable Distribution Date.

  Mandatory Distributions on Retail CitiCertificates

     To the extent, if any, that distributions in reduction of Stated Amount of
the Retail CitiCertificates on a Distribution Date exceed the remaining Stated
Amount of Retail CitiCertificates with respect to which distribution requests
have been received by the applicable date, additional Retail CitiCertificates in
lots equal to Individual Retail CitiCertificates will be selected for
distributions in accordance with the then applicable established random lot
procedures of DTC, and established procedures of the Participants and Indirect
Participants representing the Beneficial Owners of the Retail CitiCertificates
from the accounts of the Beneficial Owners. Participants and Indirect
Participants holding Retail CitiCertificates selected for mandatory
distributions in reduction of Stated Amount are required to provide notice of
such mandatory distributions to the affected Beneficial Owners.


                                      S-54

<PAGE>

     It is expected that mandatory distributions in reduction of Stated Amount
of Retail CitiCertificates are most likely to occur when prevailing interest
rates substantially decline relative to the Stated Rate on the Retail
CitiCertificates. Under such conditions, it is anticipated that fewer Beneficial
Owners would request distributions in reduction of Stated Amount and mortgagors
would be more likely to prepay the Mortgage Loans. Owners of Retail
CitiCertificates with respect to which such distributions have been made may not
be able to reinvest the proceeds of such distributions at interest rates equal
to the Stated Rate on the Retail CitiCertificates.

SUBORDINATION

     The rights of holders of the Class M CitiCertificates to receive
distributions with respect to the Mortgage Loans will be subordinated to such
rights of holders of Class A and Unoffered Class A-IO CitiCertificates to the
extent described below, the rights of holders of the Class B CitiCertificates to
receive distributions with respect to the Mortgage Loans will be subordinated to
such rights of holders of Class A, Unoffered Class A-IO and Class M
CitiCertificates to the extent described below and the rights of the holders of
the Class B Subclasses with numerically higher designations to receive
distributions with respect to the Mortgage Loans will be subordinated to such
rights of holders of Class B Subclasses with numerically lower designations to
the extent described below. This subordination is intended to enhance the
likelihood of timely receipt by holders of the Class A and Unoffered Class A-IO
CitiCertificates (to the extent of the subordination of the Class M and Class B
CitiCertificates), the Class M CitiCertificates (to the extent of the
subordination of the Class B CitiCertificates) and the Class B Subclasses with
numerically lower numbers (to the extent of the subordination of the Class B
Subclasses with numerically higher designations) of the full amount of their
scheduled monthly payments of interest and principal and to afford protection
against Realized Losses, as more fully described below. If Realized Losses
exceed the credit support provided through subordination to the Class A,
Unoffered Class A-IO or Class M CitiCertificates or numerically lower Class B
Subclasses, as the case may be, or if Excess Special Hazard Losses, Excess Fraud
Losses or Excess Bankruptcy Losses occur, all or a portion of such losses will
be borne by such Class A, Unoffered Class A-IO, Class M or Class B
CitiCertificates, as the case may be, as are then outstanding.

     The protection afforded to holders of the Class A and Unoffered Class A-IO
CitiCertificates by means of the subordination feature will be accomplished by
the preferential right of such holders to receive, prior to any distribution
being made on a Distribution Date in respect of the Class M and Class B
CitiCertificates, the amounts in reduction of Stated Amount and of interest due
the Class A and Unoffered Class A-IO CitiCertificateholders on each Distribution
Date out of the Pool Distribution Amount with respect to such date and, if
necessary, by the right of such holders to receive future distributions on the
Mortgage Loans that would otherwise have been payable to holders of Class M and
Class B CitiCertificates.

     The Class M CitiCertificates will be entitled, on each Distribution Date,
to the remaining portion, if any, of the applicable Pool Distribution Amount,
after payment of the monthly premium for the Insurance Policy, the Class A
Interest Amount, the Distributable Unoffered Class A-IO Interest Amount, any
unreimbursed Class A and Unoffered Class A-IO Unpaid Interest Shortfall, the
Class A Optimal Principal Amount and (to the extent described herein) any Unpaid
PO Loss Amounts. Amounts so distributed to Class M CitiCertificateholders will
not be available to cover delinquencies or Realized Losses in respect of
subsequent Distribution Dates.

     The Class B CitiCertificates will be entitled, on each Distribution Date,
to the remaining portion, if any, of the applicable Pool Distribution Amount,
after payment of the monthly premium for the Insurance Policy, the Class A
Interest Amount, the Distributable Unoffered Class A-IO Interest Amount, any
unreimbursed Class A and Unoffered Class A-IO Unpaid Interest Shortfall, the
Class A Optimal Principal Amount, the Class M Interest Amount, any unreimbursed
Class M Unpaid Interest Shortfall, the Class M Optimal Principal Amount and (to
the extent described herein) any Unpaid PO Loss Amounts. Amounts so distributed
to Class B CitiCertificateholders will not be available to cover delinquencies
or Realized Losses in respect of subsequent Distribution Dates.

     The protection afforded to holders of the Class B Subclasses with
numerically lower designations by means of the subordination feature will be
accomplished by the preferential right of such holders to receive, prior to any
distribution being made on a Distribution Date in respect of the Class B
Subclasses with numerically higher designations, the amounts in reduction of
Stated Amount and of interest due the holders of Class B Subclasses with
numerically lower designations on each Distribution Date out of the Pool
Distribution Amount with respect to such date (after the payment of the monthly
premium for the Insurance Policy has been made and all required payments to


                                      S-55

<PAGE>

Class A, Unoffered Class A-IO and Class M CitiCertificates and any Class B
Subclasses with a numerically lower designation have been made) and, if
necessary, by the right of such holders to receive future distributions on the
Mortgage Loans that would otherwise have been payable to holders of the Class B
Subclasses with numerically higher designations.

     The Class B Subclasses with numerically higher designations will be
entitled, on each Distribution Date, to the remaining portion, if any, of the
applicable Pool Distribution Amount, after payment of the monthly premium for
the Insurance Policy, the Class A Interest Amount, the Distributable Unoffered
Class A-IO Interest Amount, any unreimbursed Class A and Unoffered Class A-IO
Unpaid Interest Shortfall, the Class A Optimal Principal Amount, the Class M
Interest Amount, any unreimbursed Class M Unpaid Interest Shortfall, the Class M
Optimal Principal Amount, any Unpaid PO Loss Amounts (but only to extent of
Available PO Loss Funds) and any distributions in reduction of Stated Amount or
interest as to which a Class B Subclass with a lower numerical designation is
due on such date. Amounts so distributed to such Class B CitiCertificateholders
will not be available to cover delinquencies or Realized Losses in respect of
subsequent Distribution Dates.

  Allocation of Losses

     For any Distribution Date, any "Non-PO Loss Amount" shall be equal to the
applicable Non-PO Percentage of each Realized Loss (other than an Excess Special
Hazard Loss, Excess Fraud Loss or Excess Bankruptcy Loss) on a Mortgage Loan.

     Non-PO Loss Amounts will not be allocated to holders of the Class A
CitiCertificates until the date on which the amount of principal payments on the
Mortgage Loans to which holders of the Class M and Class B CitiCertificates are
entitled has been reduced to zero (the "Subordination Depletion Date"). PO Loss
Amounts will be allocated to the Class A-14 CitiCertificates until the Stated
Amount thereof has been reduced to zero. However, until the Subordination
Depletion Date, PO Loss Amounts will ultimately be borne first by the Class B
Subclasses in reverse numerical order and then by the Class M CitiCertificates,
since such losses are reimbursable from certain funds otherwise distributable on
the Class B and Class M CitiCertificates.

     The subordination of the Unoffered Class B CitiCertificates in favor of the
Class A, Unoffered Class A-IO, Class M and Offered Class B CitiCertificates,
that of the Class B-2 CitiCertificates in favor of the Class A, Unoffered Class
A-IO, Class M and Class B-1 CitiCertificates, that of the Class B-1
CitiCertificates in favor of the Class A, Unoffered Class A-IO and Class M
CitiCertificates, and that of the Class M CitiCertificates in favor of the Class
A and Unoffered Class A-IO CitiCertificates, is effected by the allocation of
Non-PO Loss Amounts first to the Unoffered Class B CitiCertificates, second to
the Class B-2 CitiCertificates, third to the Class B-1 CitiCertificates and then
to the Class M CitiCertificates, until, in each case, the respective Unoffered
Class B Stated Amount, Class B-2 Stated Amount, Class B-1 Stated Amount and
Class M Stated Amount have been reduced to zero. Non-PO Loss Amounts will be
allocated to the Class M CitiCertificates only after the Stated Amount of the
Class B CitiCertificates has been reduced to zero. Non-PO Loss Amounts will be
allocated to the Class B-1 CitiCertificates only after the Stated Amounts of the
Class B-2 and Unoffered Class B CitiCertificates have been reduced to zero and
Non-PO Loss Amounts will be allocated to the Class B-2 CitiCertificates only
after the Stated Amount of the Unoffered Class B CitiCertificates has been
reduced to zero. The effect of such allocation of Non-PO Loss Amounts (other
than Excess Special Hazard Losses, Excess Fraud Losses or Excess Bankruptcy
Losses) to the Unoffered Class B CitiCertificates and then to the Offered Class
B CitiCertificates will be to reduce future distributions to such Class B
CitiCertificates, and in particular to the Unoffered Class B CitiCertificates,
and to increase the relative portion of distributions allocable to the Class A,
Unoffered Class A-IO and Class M CitiCertificates and the Offered Class B
CitiCertificates. After the Subordination Depletion Date, the Class A and
Unoffered Class A-IO CitiCertificates will bear all Realized Losses.

     The allocation of the principal portion of Realized Losses (other than a
Debt Service Reduction, Excess Special Hazard Losses, Excess Fraud Losses and
Excess Bankruptcy Losses) will be effected, as a result of the priority of
distributions described above, by the adjustment of the Stated Amount of the
most subordinate of the Class B Subclasses then outstanding (that is, the Stated
Amount of the Class B Subclasses in reverse numerical order), and then to the
Class M CitiCertificates, in such amounts as are necessary to cause the sum of
the Class A Stated Amount, the Class M Stated Amount and the Class B Stated
Amount to equal the Pool Adjusted Balance.

     The interest portion of any Realized Loss occurring on or after the
Subordination Depletion Date will be allocated among the outstanding Class A
Subclasses and the Unoffered Class A-IO CitiCertificates, in the manner


                                      S-56

<PAGE>

described in the second succeeding paragraph. The principal portion of any
Realized Losses occurring on or after the Subordination Depletion Date will be
allocated as follows: the applicable PO Percentage of any Realized Loss will be
allocated to the Class A-14 CitiCertificates and the Non-PO Percentage of any
Realized Loss will be allocated among the other outstanding Class A
Subclasses. The principal portion of any such losses allocated to the Class A-4
and Class A-5 CitiCertificates shall be allocated among such Class A Subclass'
respective Components pro rata based on their Component Stated Amounts.

     The principal portion of Realized Losses allocated to the Class A-11
CitiCertificates will be covered by the Insurance Policy.

     Allocations of (i) the principal portion of Debt Service Reductions prior
to the Bankruptcy Termination Date, (ii) the interest portion of Realized Losses
(other than Excess Special Hazard Losses, Excess Fraud Losses and Excess
Bankruptcy Losses) and (iii) any interest shortfalls resulting from
delinquencies for which neither the Servicer nor the Trustee advances will
result from the priority of distribution of the Pool Distribution Amount first
to the Class A and Unoffered Class A-IO CitiCertificates as described below,
second to the Class M CitiCertificates, third to the Class B-1 CitiCertificates,
fourth to the Class B-2 CitiCertificates and finally to the Unoffered Class B
CitiCertificates.

     The principal portion of any Excess Special Hazard Losses, Excess Fraud
Losses or Excess Bankruptcy Losses will be allocated as follows: the applicable
PO Percentage of such Realized Losses shall be allocated to the Class A-14
CitiCertificates and the applicable Non-PO Percentage of such Realized Losses
shall be allocated on a pro rata basis among the Class A Subclasses (other than
the interest-only Class A-12 CitiCertificates and the Class A-14
CitiCertificates) and the Class M and Class B CitiCertificates based on the
aggregate Stated Amount of each such Class or Subclass or, in the case of the
Class A-6 CitiCertificates, the Initial Stated Amount, if lower. The principal
portion of any such losses allocated to the Class A-4 and Class A-5
CitiCertificates will be allocated among such Class A Subclass' respective
Components pro rata based on their Component Stated Amounts. The interest
portion of such losses with respect to the Mortgage Loans will be allocated pro
rata among the Classes of CitiCertificates based on accrued interest on each
such Class. Any interest losses so allocated to the Class A CitiCertificates
will be allocated among the outstanding Class A Subclasses (other than the Class
A-7 and Class A-14 CitiCertificates) pro rata based on interest accrued. Any
losses allocated to a particular Class A Subclass will be allocated among the
outstanding CitiCertificates within such Class A Subclass pro rata in accordance
with their notional amount or respective Stated Amount, as the case may be. Any
losses so allocated to the Unoffered Class A-IO or Class M CitiCertificates will
be allocated among the outstanding Unoffered Class A-IO or Class M
CitiCertificates, as the case may be, in accordance with their notional amount
or respective Stated Amount, as the case may be. Any losses so allocated to the
Class B CitiCertificates will be allocated among the outstanding Class B
Subclasses pro rata in accordance with their then outstanding Class B Subclass
Stated Amounts with respect to the principal portion of such losses and the
amounts of interest accrued with respect to the interest portion of such losses,
and among the outstanding CitiCertificates within each Class B Subclass pro rata
in accordance with their respective Stated Amounts.

     The interest portion of Excess Special Hazard Losses, Excess Fraud Losses
and Excess Bankruptcy Losses allocable to the CitiCertificates will be allocated
by reducing the applicable amount of accrued interest payable on the Class A,
Unoffered Class A-IO, Class M and Class B CitiCertificates. Any Excess Special
Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses allocated to the
Class A-11 CitiCertificates will be covered by the Insurance Policy.

     As described above, the Pool Distribution Amount for any Distribution Date
will include current receipts (other than certain unscheduled payments and
recoveries in respect of principal) from the Mortgage Loans otherwise payable to
holders of the Class M and Class B CitiCertificates. In general, if the Pool
Distribution Amount is not sufficient to cover the amount of the Class A Optimal
Principal Amount on a particular Distribution Date (other than with respect to
the Class A-14 CitiCertificates), the percentage of principal payments on the
Mortgage Loans to which holders of the Class A CitiCertificates (other than the
Class A-14 CitiCertificates) will be entitled (i.e., the Class A Percentage) on
and after the next Distribution Date will be proportionately increased, thereby
reducing, as a relative matter, the respective interest of the Class M and Class
B CitiCertificates in future payments of principal on the Mortgage Loans. Such a
shortfall could occur, for example, if a considerable number of Mortgage Loans
were to become Liquidated Loans in a particular month.

     Special Hazard Losses will be allocated first to the Class B Subclasses in
reverse numerical order, and then to the Class M CitiCertificates, but only
prior to the Special Hazard Termination Date. The "Special Hazard Termination


                                      S-57

<PAGE>

Date" will be the date on which such Special Hazard Losses exceed the Special
Hazard Loss Amount (or, if earlier, the Subordination Depletion Date). On the
Closing Date, the "Special Hazard Loss Amount" with respect thereto will be
equal to approximately 2.63% of the Initial Mortgage Loan Balance. As of any
Distribution Date, the Special Hazard Loss Amount will equal the initial Special
Hazard Loss Amount less the sum of (A) any Special Hazard Losses since the
Cut-Off Date and (B) the Adjustment Amount. The "Adjustment Amount" on each
anniversary of the Cut-Off Date will be equal to the amount, if any, by which
the Special Hazard Amount, without giving effect to the deduction of the
Adjustment Amount for such anniversary, exceeds the greater of (i) 1.00% (or, if
greater than 1.00%, the highest percentage of Mortgage Loans by principal
balance in any California ZIP code) times the Pool Adjusted Balance on such
anniversary and (ii) twice the Adjusted Balance of the single Mortgage Loan
having the largest Adjusted Balance. Special Hazard Losses in excess of the
Special Hazard Loss Amount are "Excess Special Hazard Losses."

     Fraud Losses will be allocated first to the Class B Subclasses in reverse
numerical order, and then to the Class M CitiCertificates, but only prior to the
Fraud Coverage Termination Date. The "Fraud Coverage Termination Date" will be
the date on which such Fraud Losses exceed the Fraud Loss Amount (or, if
earlier, the Subordination Depletion Date). On the Closing Date, the "Fraud Loss
Amount" with respect thereto will be equal to approximately 1.00% of the Initial
Mortgage Loan Balance. On each Distribution Date thereafter, the Fraud Loss
Amount will equal (X) prior to the second anniversary of the Cut-Off Date an
amount equal to the initial Fraud Loss Amount minus the aggregate amount of
Fraud Losses since the Cut-Off Date up to the related Determination Date, and
(Y) from the second through the fifth anniversary of the Cut-Off Date, an amount
equal to (1) the lesser of (a) the Fraud Loss Amount as of the most recent
anniversary of the Cut-Off Date and (b) 0.50% of the Pool Adjusted Balance as of
the most recent anniversary of the Cut-Off Date minus (2) the aggregate amount
of Fraud Losses since the most recent anniversary of the Cut-Off Date. After the
fifth anniversary of the Cut-Off Date, the Fraud Loss Amount will be zero and
thereafter any Fraud Losses will be shared pro rata among the CitiCertificates
as described above. Fraud Losses in excess of the Fraud Loss Amount are "Excess
Fraud Losses."

     Bankruptcy Losses will be allocated first to the Class B Subclasses in
reverse numerical order, and then to the Class M CitiCertificates, but only
prior to the Bankruptcy Coverage Termination Date. The "Bankruptcy Coverage
Termination Date" will be the date on which such Bankruptcy Losses exceed the
Bankruptcy Loss Amount (or, if earlier, the Subordination Depletion Date). On
the Closing Date, the "Bankruptcy Loss Amount" with respect thereto will be
equal to approximately 0.03% of the Initial Mortgage Loan Balance. As of any
Distribution Date prior to the first anniversary of the Cut-Off Date, the
Bankruptcy Loss Amount will equal the initial Bankruptcy Loss Amount minus the
aggregate amount of Bankruptcy Losses since the Cut-Off Date up to the related
Determination Date. As of any Distribution Date on or after the first
anniversary of the Cut-Off Date, the Bankruptcy Loss Amount will equal the
excess, if any, of (1) the lesser of (a) the Bankruptcy Loss Amount as of the
business day next preceding the most recent anniversary of the Cut-Off Date and
(b) $100,000 minus (2) the aggregate amount of Bankruptcy Losses since such
anniversary. The Bankruptcy Loss Amount and the related coverage levels
described above may be reduced or modified upon written confirmation from S&P
and Fitch that such reduction or modification will not adversely affect the
then-current ratings assigned to the CitiCertificates by S&P and Fitch without
regard to the Insurance Policy. Such a reduction or modification may adversely
affect the coverage provided by subordination with respect to Bankruptcy Losses.
Bankruptcy Losses in excess of the Bankruptcy Loss Amount are "Excess Bankruptcy
Losses."

     The exact amounts of Special Hazard Losses, Fraud Losses and Bankruptcy
Losses to be allocated first to the Unoffered Class B CitiCertificates, second
to the Class B-2 CitiCertificates, third to the Class B-1 CitiCertificates and
then to the Class M CitiCertificates (but in each case only prior to the related
termination date) will be those amounts required by the rating agency (or rating
agencies) rating the CitiCertificates as a condition of the ratings as set forth
above under "SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Certificate
Ratings."

     Notwithstanding the foregoing, the provisions relating to subordination
will not be applicable in connection with a Bankruptcy Loss so long as the
Servicer has notified the Trustee in writing that the Servicer is diligently
pursuing any remedies that may exist in connection with the representations and
warranties made regarding the related Mortgage Loan and when (A) the related
Mortgage Loan is not in default with regard to the payments due thereunder or
(B) delinquent payments of principal and interest under the related Mortgage
Loan and any premiums on any applicable standard hazard insurance policy and any
related escrow payments in respect of such Mortgage Loan are being advanced on a
current basis by the Servicer, in either case without giving effect to any Debt
Service Reduction.

     Since the aggregate Initial Stated Amount of the Class M and Class B
CitiCertificates will be substantially less than the Initial Stated Amount of
the Class A CitiCertificates, the risk of Special Hazard Losses, Fraud Losses
and Bankruptcy Losses will be separately borne by the Class M and Class B
CitiCertificates to a lesser extent (i.e., only up to the Special Hazard Loss
Amount, Fraud Loss Amount and Bankruptcy Loss Amount, respectively) than the
risk of other Realized Losses, which they will bear to the full extent of their
respective Initial Stated Amounts. See "APPENDIX A: THE MORTGAGE LOANS AND
CITIMORTGAGECERTIFICATES" in the Prospectus.

     The benefits of the subordination described herein will not cover
delinquencies and losses resulting from certain extraordinary events, including
(i) hostile or warlike action in time of peace or war; (ii) the use of any
weapon of war employing atomic fission or radioactive force whether in time of
peace or war; and (iii) insurrection, rebellion, revolution, civil war or any
usurped power or action taken by any governmental authority in preventing such
occurrences (but not including looting or rioting occurring not in time of war).
Losses ("Extraordinary Losses") and delinquencies resulting from such
extraordinary events will be allocated among the Class A Subclasses, Unoffered
Class A-IO CitiCertificates, Class M CitiCertificates and Class B Subclasses in
the same manner as Excess Special Hazard Losses, Excess Fraud Losses and Excess
Bankruptcy Losses. Any such losses allocated to the Class A-11 CitiCertificates
will not be covered by the Insurance Policy.

WEIGHTED AVERAGE LIVES OF THE OFFERED CITICERTIFICATES

     Weighted average life refers to the average amount of time from the date of
issuance of such CitiCertificate until each dollar of principal of such
CitiCertificate will be repaid to the investor (or, in the case of the Class
A-12 CitiCertificates, until the Class A-12 Notional Amount is reduced to zero).
The weighted average lives of the Offered CitiCertificates will be influenced by
the rate at which principal on the Mortgage Loans is paid. The weighted average
life of a Class A-12 CitiCertificate refers to the average amount of time from
the date of issuance thereof until each dollar of principal in reduction of the
initial Stated Amount of the Class A-11 CitiCertificates is paid to investors in
the Class A-11 CitiCertificates. Principal payments on mortgage loans may be in
the form of scheduled amortization or prepayments (for this purpose, the term
"prepayment" includes prepayments and liquidations due to default or other
dispositions of mortgage loans). Prepayments on mortgage loans are commonly
measured by a prepayment standard or model. The model used in this Prospectus
Supplement (the "Prepayment Model") is based on an assumed rate of prepayment
each month relative to the then unpaid principal balance of a pool of new
mortgage loans. 100% of the Prepayment Model assumes prepayment rates of 0.2%
per annum of the then unpaid principal balance of such mortgage loans in the
first month of the life of the mortgage loans and an additional 0.2% per annum
in each month thereafter (for example, 0.4% per annum in the second month) until
the 30th month. Beginning in the 30th month and in each month thereafter during
the life of the mortgage loans, 100% of the Prepayment Model assumes a constant
prepayment rate of 6.0% per annum.

     As used in the following tables, "0% of the Prepayment Model" assumes no
prepayments on the Mortgage Loans; "275% of the Prepayment Model" assumes such
Mortgage Loans will prepay at rates equal to 275% of the Prepayment Model's
assumed prepayment rates and so forth.

     There is no assurance, however, that prepayment of the Mortgage Loans will
conform to any level of the Prepayment Model. The rate of principal payments on
pools of mortgage loans is influenced by a variety of economic, geographic,
social and other factors, including the level of mortgage interest rates and the
rate at which homeowners sell their homes or default on their mortgage loans. In
general, if prevailing interest rates fall significantly below the interest
rates on the Mortgage Loans, the Mortgage Loans are likely to be subject to
higher prepayment rates than if prevailing rates remain at or above the interest
rates on such Mortgage Loans. Conversely, if interest rates rise above the
interest rates on such Mortgage Loans, the rate of prepayment would be expected
to decrease. Other factors affecting prepayment of mortgage loans include
changes in mortgagors' housing needs, job transfers, unemployment and
mortgagors' net equity in the mortgaged properties. In addition, as homeowners
move or default on their mortgage loans, the houses are generally sold and the
mortgage loans prepaid, although some of the mortgage loans may be assumed by a
new buyer. Because the amount of distributions in reduction of the Stated Amount
of each Class A Subclass, the Class M CitiCertificates and each Offered Class B
Subclass will depend on the rate of repayment (including prepayments) of the
Mortgage Loans, the date by which the Stated Amount of any Class A Subclass, the
Class M CitiCertificates or any Offered Class B Subclass is reduced to zero is
likely to occur earlier than its respective Last Scheduled Distribution Date.

     THE WEIGHTED AVERAGE LIVES OF THE OFFERED CITICERTIFICATES, PARTICULARLY
THE CLASS A SUBCLASSES THAT SUPPORT THE PAC CERTIFICATES, AS WELL AS THE YIELDS
TO MATURITY OF THE OFFERED CITICERTIFICATES TO THE EXTENT THAT SUCH
CITICERTIFICATES ARE PURCHASED AT A DISCOUNT OR PREMIUM, WILL BE PARTICULARLY
SENSITIVE (OR, IN THE CASE OF THE CLASS A SUBCLASSES THAT SUPPORT THE PAC
CERTIFICATES, HIGHLY SENSITIVE) TO THE RATE OF PRINCIPAL PAYMENTS (INCLUDING
PREPAYMENTS) ON THE MORTGAGE LOANS. On each Distribution Date, the excess, if
any, of the portion of the Class A Non-PO Principal Amount available to make
distributions in reduction of Stated Amounts to the PAC Certificates over the
PAC Balance Amounts for such Distribution Date will be allocated to the Class
A-3, Class A-4, Class A-5, Class A-6 and Class A-7 CitiCertificates, as
otherwise provided herein. As a result, the weighted average lives of the Class
A Subclasses that support the PAC Certificates will be relatively more sensitive
to faster prepayment rates than that of the PAC Certificates, and may be
significantly more sensitive than would be the case if the Class A
CitiCertificates did not include the PAC Certificates. Conversely, under certain
relatively slow prepayment scenarios, the PAC Balance Amounts for the PAC
Certificates may not be paid in full on a given Distribution Date. In such case,
the portion of the Class A Non-PO Principal Amount available to make
distributions in reduction of Stated Amounts to the PAC Certificates for each
subsequent Distribution Date will be applied first to the PAC Certificates until
the current Stated Amounts thereof equal their respective Planned Balances and,
as a result, the weighted average lives of the Subclasses that support the PAC
Certificates may be extended accordingly.

     The weighted average lives of the TAC Certificates and the Class A-4 and
Class A-5 CitiCertificates with respect to their TAC Components will depend upon
the particular prepayment scenario. To the extent that principal prepayments are
made at rates that are continuously slower than 125% of the Prepayment Model,
the weighted average lives of the TAC Certificates and the Class A-4 and Class
A-5 CitiCertificates with respect to their TAC Components may be extended (and
may be extended significantly). To the extent that such principal prepayments
are made at rates that are continuously faster than 125% of the Prepayment
Model, the weighted average lives of the TAC Certificates and the Class A-4 and
Class A-5 CitiCertificates with respect to their TAC Components may be reduced
(and may be reduced significantly).

     The sensitivity of the TAC Certificates and the TAC Components to principal
prepayments on the Mortgage Loans and the allocation of the Accretion
Distribution Amount of the Class A-6 CitiCertificates to such Class A Subclass
and Components will depend in part upon the period of time during which the
Class A-4 CitiCertificate (Component 2) and the Class A-5 CitiCertificate
(Component 2) remain outstanding. Under certain relatively fast prepayment
scenarios, the TAC Certificates and the TAC Components may continue to be
outstanding when the Class A-4 CitiCertificate (Component 2) and the Class A-5
CitiCertificate (Component 2) are no longer outstanding. Under such
circumstances, the portion of the Class A Non-PO Principal Amount available to
make distributions in reduction of Stated Amount to the TAC Certificates and the
Component Stated Amounts of the TAC Components will be applied to the TAC
Certificates and the TAC Components without regard to their related TAC Balance
Amounts. Thus, when the Component Stated Amounts of the Class A-4
CitiCertificate (Component 2) and the Class A-5 CitiCertificate (Component 2)
are reduced to zero, the rate of distributions in reduction of the Stated Amount
of the TAC Certificates and the Component Stated Amounts of the TAC Components
will become more sensitive to prepayment rates on the Mortgage Loans.
Conversely, under certain relatively slow prepayment scenarios, the portion of
the Class A Non-PO Principal Amount available to make distributions in reduction
of Stated Amount to the TAC Certificates and the Component Stated Amounts of the
TAC Components and the Accretion Distribution Amount of the Class A-6
CitiCertificates may not be sufficient to pay the TAC Balance Amounts for the
TAC Certificates Component on a given Distribution Date. In such cases, the
portion of the Class A Non-PO Principal Amount available to make distributions
in reduction of Stated Amount to the TAC Certificates and the Component Stated
Amounts of the TAC Components for each subsequent Distribution Date will be
applied, together with any Accretion Distribution Amount for such Distribution
Date, to the TAC Certificates and the TAC Components until their outstanding
Stated Amount and Component Stated Amounts equal their scheduled Targeted
Balances.

     The weighted average lives of the Class A Subclasses of PAC Certificates
will depend upon the particular prepayment scenario. To the extent that
principal prepayments are made at rates that are continuously slower than the
lowest rate in the range of 100% to 400% of the Prepayment Model, the weighted
average life of any Class A Subclass of PAC Certificates may be extended (and
may be extended significantly). To the extent that such principal prepayments
are made at rates that are continuously faster than the highest rate in the
range of 100% to 400% of the Prepayment Model, the weighted average life of any
Class A Subclass of PAC Certificates may be reduced (and may be reduced
significantly).

     The sensitivity of the PAC Certificates to principal prepayments on the
Mortgage Loans will depend in part upon the period of time during which the
Class A-3, Class A-4, Class A-5, Class A-6 and Class A-7 CitiCertificates (the
"PAC Support Classes") remain outstanding. Under certain relatively fast
prepayment scenarios, one or both of the Class A Subclasses of PAC Certificates
may continue to be outstanding when the PAC Support Classes are no longer
outstanding. Under such circumstances, the portion of the Class A Non-PO
Principal Amount available to make distributions in reduction of Stated Amount
to the PAC Certificates will be applied to the PAC Certificates as described
herein, without regard to the PAC Balance Amounts for such Class A Subclasses of
PAC Certificates. Thus, when the Stated Amounts of the PAC Support Classes are
reduced to zero, the rate of distributions in reduction of Stated Amount of any
outstanding Class A Subclass of PAC Certificates will become more sensitive to
prepayment rates on the Mortgage Loans. Conversely, under certain relatively
slow prepayment scenarios, the portion of the Class A Non-PO Principal Amount
available to make distributions in reduction of Stated Amount to the PAC
Certificates may not be sufficient to pay the PAC Balance Amounts for all Class
A Subclasses of PAC Certificates on a given Distribution Date. In such cases,
the portion of the Class A Non-PO Principal Amount available to make
distributions in reduction of Stated Amount to the PAC Certificates for each
such subsequent Distribution Date will be applied to the Class A Subclasses of
PAC Certificates in accordance with the priorities described herein until the
outstanding Stated Amount of each such Class A Subclass equals its scheduled
Planned Balance, and the weighted average life of any Class A Subclass of PAC
Certificates that did not receive its PAC Balance Amount on a Distribution Date
may be extended accordingly.

     As described above under "SUMMARY OF PROSPECTUS AND PROSPECTUS
SUPPLEMENT--Distributions in Reduction of Stated Amount of the Offered
CitiCertificates," on each Distribution Date holders of the Class A
CitiCertificates (other than the Class A-14 CitiCertificates) will be entitled
to receive the Class A Percentage of the applicable Non-PO Percentage of all the
Scheduled Principal, and the Class A Prepayment Percentage of the applicable
Non-PO Percentage of the net proceeds of Liquidated Loans and of the prepayment
principal. This will have the effect of accelerating the amortization of the
Class A CitiCertificates while, in the absence of losses in respect of
Liquidated Loans, increasing the respective interest in the Trust evidenced by
the Class M and Class B CitiCertificates.

     The following table has been prepared on the basis of the expected
characteristics of the Mortgage Loans as set forth under "DESCRIPTION OF THE
POOL AND THE MORTGAGED PROPERTIES" herein. The percentages and weighted average
lives in the following table were determined assuming that (i) scheduled
interest and principal payments on the Mortgage Loans will be received in a
timely manner and prepayments are made at the indicated percentages of the
Prepayment Model set forth in the table; (ii) each Discount Mortgage Loan and
Premium Mortgage Loan will have an original term to maturity of 360 months and
359 months, respectively, a weighted average remaining term to stated maturity
of 359 months and 357 months, respectively, a rate of interest passed through to
holders of the CitiCertificates of approximately 6.2876153016% and
7.1388077559%, respectively, and, in each case, a Servicing Fee of 0.25% per
annum; (iii) CMSI does not exercise its right of optional termination; (iv) the
Initial Stated Amounts of the Class B-3, Class B-4 and Class B-5
CitiCertificates are approximately $1,062,000, $607,000, and $910,697,
respectively; (v) the Initial Mortgage Loan Balance of Discount Mortgage Loans
and Premium Mortgage Loans are approximately $574,469 and approximately
$302,884,998, respectively, and for each Class A Subclass, the Class M
CitiCertificates and each Offered Class B Subclass, the Initial Stated Amount
and the Stated Rate are as set forth on the cover page hereof; (vi) the Closing
Date is July 29, 1998; (vii) distribution in reduction of Stated Amount of the
Retail CitiCertificates are made pro rata to the holders thereof and are not
rounded to integral multiples of $1,000, as described under the heading
"--Distributions in Reduction of Stated Amount of the Retail CitiCertificates;"
and (viii) distributions to holders of the CitiCertificates will be made on the
25th day of each month commencing August 1998 (the foregoing assumptions are
referred to herein as the "Structuring Assumptions").

     There are likely to be discrepancies between the characteristics of the
actual Mortgage Loans and the characteristics of the Mortgage Loans assumed in
preparing the following table. Any such discrepancy may have an effect upon the
percentages of the Initial Stated Amount (or initial notional amount)
outstanding (and the weighted average lives) of the Class A Subclasses, the
Class M CitiCertificates and the Offered Class B Subclasses set forth in the
table. In addition, to the extent that the actual Mortgage Loans have
characteristics that differ from those assumed in preparing the table set forth
below, the Stated Amount (or notional amount) of each Class A Subclass, the
Class M CitiCertificates and each Offered Class B Subclass may be reduced to
zero earlier or later than indicated by such table.

     It is not likely that (i) all of the Mortgage Loans will have the remaining
terms to stated maturity assumed, (ii) the Mortgage Loans will prepay at the
indicated percentages of the Prepayment Model set forth in the table, or (iii)
all of the Discount Mortgage Loans or all of the Premium Mortgage Loans will
have the respective mortgage interest rates assumed by the Structuring
Assumptions. In addition, the diverse remaining terms to maturity of the
Mortgage Loans (which may include recently originated Mortgage Loans) could
produce slower distributions in reduction of Stated Amounts (or initial notional
amounts) than indicated in the table at the various percentages of the
Prepayment Model specified even if the weighted average remaining terms to
stated maturity of the Mortgage Loans are those assumed.

     Based on the foregoing assumptions, the following table indicates the
projected weighted average life of each Class A Subclass, the Class M
CitiCertificates and each Offered Class B Subclass and sets forth the percentage
of the Initial Stated Amount (or initial notional amount) of each Class A
Subclass, the Class M CitiCertificates and each Offered Class B Subclass that
would be outstanding after each of the dates shown at the indicated percentages
of the Prepayment Model.

      case may be) by the number of years from the date of issuance of the
      Offered CitiCertificates to the related Distribution Date, (ii) adding the
      results and (iii) dividing the sum by the Initial Stated Amount (or
      notional amount, as the case may be) of the Class or Subclass of the
      Offered CitiCertificates.

PREPAYMENT AND YIELD CONSIDERATIONS

     The yield to maturity and weighted average lives of the Offered
CitiCertificates will be sensitive in varying degrees to, among other things,
the rate of prepayment of the Mortgage Loans, the allocation of such prepayments
to the Class A, Unoffered Class A-IO, Class M and Class B CitiCertificates and
the timing and extent of losses, if any, allocable to the Class A, Unoffered
Class A-IO, Class M and Class B CitiCertificates. No representation is made as
to whether the Mortgage Loans will prepay at any particular rate.

     The yield to maturity on the Offered Class B CitiCertificates will be more
sensitive than the yield to maturity on the Class A, Unoffered Class A-IO and
Class M CitiCertificates to losses due to defaults on the Mortgage Loans (and
the timing thereof), to the extent not covered by the Unoffered Class B
CitiCertificates, because the entire amount of such losses will be allocable to
the Offered Class B CitiCertificates in reverse numerical order prior to the
Class A and Class M CitiCertificates except as otherwise provided herein. To the
extent not covered by advances, delinquencies on Mortgage Loans may also have a
relatively greater effect on the yield to investors in the Offered Class B
CitiCertificates. Amounts otherwise distributable to holders of the Offered
Class B CitiCertificates will be made available to protect holders of the Class
A, Unoffered Class A-IO and Class M CitiCertificates against interruptions in
distributions due to certain mortgagor delinquencies. Such delinquencies, to the
extent not covered by the Unoffered Class B CitiCertificates, even if
subsequently cured, may affect the timing of the receipt of distributions by
holders of the Offered Class B CitiCertificates, because the entire amount of
those delinquencies would be borne by the Offered Class B Subclasses in reverse
numerical order prior to the Class A, Unoffered Class A-IO and Class M
CitiCertificates.

     If the purchaser of an Offered CitiCertificate offered at a discount from
its parity price (as described below) calculates the anticipated yield to
maturity of such Offered CitiCertificate based on an assumed rate of payment of
principal that is faster than that actually received on the Mortgage Loans,
assuming all other relevant circumstances are unchanged, the actual yield to
maturity will be lower than that so calculated. If the purchaser of an Offered
CitiCertificate which was instead offered at a premium over its parity price or
the purchaser of a Class A-12 CitiCertificate which has no Stated Amount
calculates the anticipated yield to maturity of such Offered CitiCertificate on
an assumed rate of payment of principal that is slower than that actually
received on the Mortgage Loans, assuming all other relevant circumstances are
unchanged, the actual yield to maturity will be lower than that so calculated.
Parity price is the price at which an Offered CitiCertificate will yield its
coupon, after giving effect to any payment delay.

     The timing of changes in the rate of prepayments on the Mortgage Loans may
significantly affect an investor's actual yield to maturity, even if the average
rate of principal payments is consistent with an investor's expectation. In
general, the earlier a prepayment of principal on the Mortgage Loans the greater
the effect on an investor's yield to maturity. As a result, the effect on an
investor's yield of principal payments occurring at a rate higher (or lower)
than the rate anticipated by the investor during the period immediately
following the issuance of the Offered CitiCertificates will not be offset by a
subsequent like reduction (or increase) in the rate of principal payments.

     As described under "DESCRIPTION OF THE OFFERED CITICERTIFICATES--
Distributions in Reduction of Stated Amount" herein, all or a disproportionate
percentage of principal prepayments on the Mortgage Loans (including
liquidations and repurchases of Mortgage Loans) will be distributed, to the
extent of the Non-PO Percentage, to the holders of the Class A CitiCertificates
(other than the Class A-14 CitiCertificates) then entitled to distributions in
respect of principal during the nine years beginning on the first Distribution
Date, and, to the extent that such principal prepayments are made in respect of
a Discounted Mortgage Loan, to the Class A-14 CitiCertificates in proportion to
the interest of the Class A-14 CitiCertificates in such Discount Mortgage Loan
represented by the PO Percentage. The holders of the Class A-13 CitiCertificates
will not be entitled to receive any distributions in reduction of the Stated
Amount prior to the Distribution Date in August 2003, and prior to the
Distribution Date in August 2007 will receive a disproportionately small portion
of principal prepayments and other unscheduled recoveries on the Mortgage Loans,
unless the Stated Amounts of all other Class A Subclasses (other than the Class
A-14 CitiCertificates) have been reduced to zero or the Stated Amounts of the
Subordinated CitiCertificates have been reduced to zero. As a result, the
weighted average life will be longer, and could be significantly longer, than
would be the case if the Class A-13 CitiCertificates received their pro rata
share of the Class A Percentage and Class A Prepayment Percentage of the Non-PO
Percentage of all principal payments received on the Mortgage Loans.

     The Issuer intends to file certain additional yield tables and other
computational material with respect to one or more Class A Subclasses, the Class
M CitiCertificates and the Offered Class B Subclasses with the Commission in a

Report on Form 8-K. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE"
herein. Such tables and materials were prepared by the Underwriters at the
request of certain prospective investors, based on assumptions provided by, and
satisfying the special requirements of, such investors. Such tables and
assumptions may be based on assumptions that differ from the Structuring
Assumptions. Accordingly, such tables and other materials may not be relevant to
or appropriate for investors other than those specifically requesting them.

     Because the rate of principal payments (including prepayments) on the
Mortgage Loans may significantly affect the weighted average life and other
characteristics on any Class A Subclass, the Class M CitiCertificates or any
Offered Class B Subclass, prospective investors are urged to consult their
investment advisors and to consider their own estimates as to the anticipated
rate of future prepayments on the Mortgage Loans and the suitability of the
Class A CitiCertificates, the Class M CitiCertificates and Offered Class B
CitiCertificates to their investment objectives.

SENSITIVITY OF THE CLASS A-7 CITICERTIFICATES

     THE YIELD TO INVESTORS IN THE CLASS A-7 CITICERTIFICATES WILL BE EXTREMELY
SENSITIVE TO THE RATE AND TIMING OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS)
OF THE MORTGAGE LOANS, WHICH RATE MAY FLUCTUATE SIGNIFICANTLY FROM TIME TO TIME.
INVESTORS SHOULD FULLY CONSIDER THE ASSOCIATED RISKS, INCLUDING THE RISK THAT A
RELATIVELY LOW RATE OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) ON THE
MORTGAGE LOANS WILL HAVE A NEGATIVE EFFECT ON THE YIELD TO INVESTORS IN THE
CLASS A-7 CITICERTIFICATES.

     The following table indicates the sensitivity to various rates of
prepayment on the Mortgage Loans of the pre-tax yields to maturity on a
corporate bond equivalent basis of the Class A-7 CitiCertificates. Such
calculations are based on distributions made in accordance with "DESCRIPTION OF
THE OFFERED CITICERTIFICATES--Distributions in Reduction of Stated Amount"
herein, on the Structuring Assumptions under the heading "DESCRIPTION OF THE
OFFERED CITICERTIFICATES--Weighted Average Lives of the Offered
CitiCertificates" and on the further assumption that the Class A-7
CitiCertificates will be purchased on July 29, 1998 at an aggregate purchase
price equal to approximately 75% of the Initial Stated Amount thereof.

Class A-7 .............      1.13%      1.83%      5.52%      11.08%      16.72%

     The pre-tax yields set forth in the preceding table were calculated by (i)
determining the monthly discount rates which, when applied to the assumed stream
of cash flows to be paid on the Class A-7 CitiCertificates, would cause the
discounted present value of such assumed stream of cash flows to equal an
assumed purchase price for each Class A-7 CitiCertificate equal to 75% of the
Initial Stated Amount thereof and (ii) converting such monthly rates to
corporate bond equivalent rates. Such calculation does not take into account the
interest rates at which investors may be able to reinvest funds received by them
as distributions on the Class A-7 CitiCertificates and consequently does not
purport to reflect the return on any investment in Class A-7 CitiCertificates
when such reinvestment rates are considered.

     Notwithstanding the assumed prepayment rate reflected in the preceding
table, it is highly unlikely that the Mortgage Loans will prepay at a constant
rate until maturity or that all of the Mortgage Loans will prepay at the same
time. There are likely to be discrepancies between the characteristics of the
actual Mortgage Loans and the characteristics of the Mortgage Loans assumed in
preparing the table. As a result of these factors, the pre-tax yields on the
Class A-7 CitiCertificates are likely to differ from those shown in such table,
even if all of the Mortgage Loans prepay at the indicated percentages of the
Prepayment Model.

SENSITIVITY OF THE CLASS A-12 CITICERTIFICATES

     THE YIELD TO INVESTORS IN THE CLASS A-12 CITICERTIFICATES WILL BE HIGHLY
SENSITIVE TO THE RATE OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS) ON THE
MORTGAGE LOANS. A HIGH RATE OF PREPAYMENTS WILL HAVE A MATERIAL NEGATIVE EFFECT
ON THE YIELD TO INVESTORS IN THE CLASS A-12 CITICERTIFICATES AND MAY RESULT IN
THE FAILURE OF SUCH INVESTORS TO FULLY RECOVER THEIR INITIAL INVESTMENTS.

<PAGE>

     To illustrate the significance of changes in the level prepayments on the
Class A-12 CitiCertificates, the following table indicates the pre-tax yields to
maturity (on a corporate bond equivalent basis) under the assumptions specified
in the following paragraph. It is highly unlikely that the Mortgage Loans will
repay at a constant level of the Prepayment Model until maturity or that all of
the Mortgage Loans will prepay at the same rate. As discussed above, the timing
of changes in the rate of prepayments may significantly affect total
distributions received, the date of receipt of such distribution and the actual
yield to maturity to an investor in a Class A-12 CitiCertificates, even if the
average rate of principal prepayments is consistent with such investor's
expectations.

     The following table has been prepared on the basis of the Structuring
Assumptions described under the heading "--Weighted Average Lives of the Offered
CitiCertificates," and the additional assumptions that (i) the aggregate
purchase price for the Class A-12 CitiCertificates is $50,777.78 (which price
includes accrued interest) and (ii) such purchase price is paid on July 29,
1998. The Mortgage Loans will not have all the characteristics assumed above and
there can be no assurance that the Mortgage Loans will prepay at any of the
constant rates shown in the table or at any other particular rate, the rate
pre-tax yield to maturity on the Class A-12 CitiCertificates will correspond to
any of the amounts shown herein or that the aggregate purchase price of the
Class A-12 CitiCertificates will be equal to that assumed. Each investor must
make an independent decision as to the appropriate prepayment assumptions to be
used in deciding whether to purchase a Class A-12 CitiCertificate.

     The pre-tax yields set forth in the following table were calculated by (i)
determining the monthly discount rates which, when applied to the assumed stream
of cash flows to be paid on the Class A-12 CitiCertificates, would cause the
discounted present value of such assumed stream of cash flows to equal an
assumed aggregate purchase price for the Class A-12 CitiCertificates of
$50,777.78 (which price includes accrued interest) and (ii) converting such
monthly rates to corporate bond equivalent rates. Such calculations do not take
into account the interest rates at which investors may be able to reinvest funds
received by them as distributions on the Class A-12 CitiCertificates and
consequently do not purport to reflect the return on any investment in Class
A-12 CitiCertificate when such reinvestment rates are considered.

SENSITIVITY OF THE CLASS A-14 CITICERTIFICATES

     THE YIELD TO INVESTORS IN THE CLASS A-14 CITICERTIFICATE WILL BE EXTREMELY
SENSITIVE TO THE RATE AND TIMING OF PRINCIPAL PAYMENTS (INCLUDING PREPAYMENTS)
ON THE DISCOUNT MORTGAGE LOANS, WHICH RATE MAY FLUCTUATE SIGNIFICANTLY FROM TIME
TO TIME. BECAUSE PAYMENTS IN REDUCTION OF THE STATED AMOUNT OF CLASS A-14
CITICERTIFICATE WILL BE DIRECTLY RELATED TO THE RATE OF PRINCIPAL PAYMENTS ON
THE DISCOUNT MORTGAGE LOANS, PAYMENTS IN REDUCTION OF THE CLASS A-14
CITICERTIFICATE WILL BE DIFFERENT AND MOST LIKELY SLOWER THAN THE POOL TAKEN AS
A WHOLE.

     The following table indicates sensitivity to various rates of prepayment on
the Discount Mortgage Loans of the pre-tax yields to maturity on a corporate
bond equivalent basis of the Class A-14 CitiCertificate. Such calculations are
based on distributions made in accordance with "DESCRIPTION OF THE OFFERED
CITICERTIFICATES--Distributions in Reduction of Stated Amount of the Offered
CitiCertificates" herein, on the Structuring Assumptions which pertain to the
Discount Mortgage Loans described under the heading "DESCRIPTION OF THE OFFERED
CITICERTIFICATES--Weighted Average Lives of the Offered CitiCertificates" and on
the further assumption that the Class A-14 CitiCertificate will be purchased on
July 29, 1998 at an aggregate purchase price equal to approximately 71.00% of
the Initial Stated Amount thereof.

     The pre-tax yields set forth in the preceding table were calculated by (i)
determining the monthly discount rates which, when applied to the assumed stream
of cash flows to be paid on the Class A-14 CitiCertificates, would cause the
discounted present value of such assumed stream of cash flows to equal an
assumed purchase price for each Class A-14 CitiCertificate equal to 71.00% of
the Initial Stated Amount thereof and (ii) converting such monthly rates to
corporate bond equivalent rates. Such calculation does not take into account the
interest rates at which investors may be able to reinvest funds received by them
as distributions on the Class A-14 CitiCertificates and consequently does not
purport to reflect the return on any investment in Class A-14 CitiCertificates
when such reinvestment rates are considered.

     Notwithstanding the assumed prepayment rate reflected in the preceding
table, it is highly unlikely that the Discount Mortgage Loans will prepay at a
constant rate until maturity or that all of the Discount Mortgage Loans will
prepay at the same time. A lower than anticipated rate of principal prepayments
on the Discount Mortgage Loans will have an adverse effect on the yield to
maturity of the Class A-14 CitiCertificates. Because the Discount Mortgage Loans
have NNRs that are lower than the NNRs of the Premium Mortgage Loans, the
Discount Mortgage Loans are generally likely to prepay at a lower rate under
most circumstances. There are likely to be discrepancies between the
characteristics of the actual Discount Mortgage Loans and the characteristics of
the Discount Mortgage Loans assumed in preparing the table. As a result of these
factors, the pre-tax yields on the Class A-14 CitiCertificates are likely to
differ from those shown in such table, even if all of the Discount Mortgage
Loans prepay at the indicated percentages of the Prepayment Model. Investors are
urged to make their investment decisions based on their determinations as to
anticipated rates of prepayment under a variety of scenarios.

YIELD CONSIDERATIONS WITH RESPECT TO THE OFFERED CLASS B CITICERTIFICATES

     If the Unoffered Class B Stated Amount has been reduced to zero, the yield
to maturity on the Offered Class B CitiCertificates will become extremely
sensitive to losses on the Mortgage Loans and the timing thereof, because the
entire amount of such losses (other than Excess Fraud Losses, Excess Special
Hazard Losses and Excess Bankruptcy Losses, as described herein) will be
allocated first to the Class B-2 CitiCertificates until the Stated Amount
thereof has been reduced to zero, and then to the Class B-1 CitiCertificates.

     Defaults on the Mortgage Loans may be measured relative to a default
standard or model. The model used in the following tables, the standard default
assumption ("SDA"), represents an assumed rate of default each month relative to
the then outstanding principal balance of a pool of new mortgage loans. A
default assumption of 100% SDA assumes constant default rates of 0.02% per annum
of the then outstanding principal balance of such mortgage loans in the first
month of the life of the mortgage loans and an additional 0.02% per annum in
each month thereafter until the 30th month. Beginning in the 30th month and in
each month thereafter through the 60th month of the life of the mortgage loans,
100% SDA assumes a constant default rate of 0.60% per annum each month.
Beginning in the 61st month and in each month thereafter through the 120th month
of the life of the mortgage loans, 100% SDA assumes that the constant default
rate declines each month by 0.0095% per annum, and that the constant default
rate remains at 0.03% per annum in each month after the 120th month. As used in
the table below, "50% SDA" assumes default rates equal to the product of 0.50
and the 100% SDA assumed default rate, "100% SDA" assumes default rates equal to
the product of 1.00 and the 100% SDA assumed default rate, "150% SDA" assumes
default rates equal to the product of 1.50 and the 100% SDA assumed default rate
and so forth. SDA does not purport to be a historical description of default
experience or a prediction of the anticipated rate of default of any pool of
mortgage loans, including the Mortgage Loans.

     The following yield tables have been prepared using the Structuring
Assumptions, except that, in lieu of clause (i) of the Structuring Assumptions,
it was assumed that (i) scheduled interest and principal payments on the
Mortgage Loans are received timely, other than with respect to Mortgage Loans on
which it is assumed the defaults occur monthly in accordance with the indicated
percentages of SDA. In addition, it was assumed that (i) realized losses on
liquidations of a specified percentage of the outstanding principal balance of
such liquidated Mortgage Loans, as indicated in the table (referred to as the
"Loss Severity Percentage"), will occur at the time of liquidation which shall
be twelve months after the date of default; (ii) there are no Excess Special
Hazard Losses, Excess Fraud Losses or Excess Bankruptcy Losses; (iii) reductions
of the Class A Prepayment Percentage are taken only when permitted as described
under "DESCRIPTION OF THE OFFERED CITICERTIFICATES--Distributions in Reduction
of Stated Amount" in this Prospectus Supplement, and that there are no
delinquent loans other than Liquidated Loans; and (iv) there are no
Non-Supported Interest Shortfalls.


                                      S-72

<PAGE>

     The rate of distributions in reduction of Stated Amount on the Offered
Class B CitiCertificates will be directly related to the actual amortization
schedule of the Mortgage Loans; accordingly, the interest distributions and
distributions in reduction of Stated Amount received on the Offered Class B
CitiCertificates may result in pre-tax yields which differ from those reflected
below. The Mortgage Loans will not have the characteristics assumed, and it is
unlikely that they will prepay at any of the rates specified. The assumed
percentages of liquidations and loss severities on the Mortgage Loans shown in
the table below are for illustrative purposes only and the Issuer makes no
representations with respect to the reasonableness of such assumptions or that
the actual liquidation and loss severity experience of the Mortgage Loans will
in any way correspond to any of the assumptions made herein. Consequently, there
can be no assurance that the pre-tax yield to an investor in the Offered Class B
CitiCertificates will correspond to any of the pre-tax yields shown below.

     The pre-tax yields set forth in the following tables were calculated by
determining the monthly discount rates which, when applied to the assumed
streams of cash flows to be paid on the Offered Class B CitiCertificates, would
cause the discounted present value of such assumed streams of cash flows as of
July 29, 1998 to equal the respective assumed purchase prices indicated plus
accrued interest at the Stated Rate from (and including) the Cut-Off Date to
(but excluding) July 29, 1998, and converting such monthly rates to corporate
bond equivalent rates. Such calculation does not take into account variations
that may occur in the interest rates at which investors may be able to reinvest
funds received by them as reductions of the Stated Amount on the Offered Class B
CitiCertificates and consequently does not purport to reflect the return on any
investment in Offered Class B CitiCertificates when such reinvestment rates are
considered. The assumed purchase price is equal to the percentage stated in each
table.

OPTIONAL TERMINATION

     Holders of all outstanding CitiCertificates may receive a distribution
reducing the Stated Amount of such CitiCertificates to zero upon the repurchase
by CMSI of the underlying Mortgage Loans and any property acquired in respect
thereof in full, at CMSI's option, at any time after the Pool Adjusted Balance
is less than 5% of the Initial Mortgage Loan Balance, provided CMSI has received
an opinion of counsel or other evidence that such repurchase and the related
distribution will constitute a "qualified liquidation" within the meaning of
Code Section 860F(a)(4)(A), will not affect the REMIC status of the Trust and
will not otherwise subject the Trust to tax. CMSI reserves the right to transfer
its right to repurchase the Mortgage Loans as described above to any third
party. See "THE POOLING AGREEMENTS--Termination; Repurchase of Mortgage Loans
and Mortgage Certificates" in the Prospectus. Any such final distribution in
reduction of Stated Amount with respect to the CitiCertificates will be paid to
Certificateholders in order of their priority of distribution as described under
"SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Priority of Distributions."
The proceeds from such a distribution may not be sufficient to distribute the
full amount to which each Class is entitled if the purchase price is based in
part on the fair market value of the acquired property of the Trust.

TRUSTEE AND AGENTS

     The trustee for the CitiCertificates will be State Street Bank and Trust
Company, which will also act as Paying Agent, Transfer Agent and Certificate
Registrar for the CitiCertificates.

SERVICING COMPENSATION

     CMSI will act as servicer of the Mortgage Loans, as well as REMIC servicer
for the Pool (together, the "Servicer"). CMSI will be entitled to Servicing
Compensation equal to a monthly fee of 0.25% per annum of the aggregate Adjusted
Balance of the Mortgage Loans (the "Servicing Fee"), payable from interest
payments received in respect of the Mortgage Loans, as well as late payment
charges, assumption fees and other similar amounts set forth in the Pooling
Agreement. CMSI currently intends to subcontract its duties as Servicer of the
Mortgage Loans to CMI.

     The Servicer will pay the expenses of the Trust, including the Trustee's
fee, accounting fees and other related expenses. See "DESCRIPTION OF
CERTIFICATES--The Servicer" in the Prospectus.

BOOK-ENTRY REGISTRATION

     Each of the Offered Senior CitiCertificates (other than the Class A-14
CitiCertificates) will initially be issued in book-entry form and will be
represented by a single physical certificate registered in the name of Cede, as
nominee of DTC, which will be the "holder" or "Certificateholder" of such Class
A CitiCertificates as such terms are used herein. No Beneficial Owner will be
entitled to receive a certificate representing such person's interest in the
Book-Entry CitiCertificates or the Trust, except as set forth below under
"--Definitive Certificates." Unless and until Definitive Certificates (as
defined herein) are issued under the limited circumstances described herein, all


                                      S-74

<PAGE>

references to actions taken by Certificateholders or holders shall refer to
actions taken by DTC upon instructions from its Participants (as defined below),
and all references herein to distributions and notices of redemption to
Certificateholders or holders shall refer to distributions and notices of
redemption to DTC or Cede, as the registered holder of the Book-Entry
CitiCertificates for distribution to Participants in accordance with DTC
procedures.

     DTC is a limited purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the Uniform Commercial Code as adopted in the
State of New York and a "clearing agency" registered pursuant to Section 17A of
the Securities Exchange Act of 1934, as amended. DTC was created to hold
securities for its participating organizations ("Participants") and to
facilitate the clearance and settlement of securities transactions between
Participants through electronic book-entries, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers (including the Underwriter), banks, trust companies and clearing
corporations. Indirect access to the DTC system also is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").

     Under the rules, regulations and procedures creating and affecting DTC and
its operations (the "Rules"), DTC is required to make book-entry transfers of
Book-Entry CitiCertificates among Participants on whose behalf it acts with
respect to the Book-Entry CitiCertificates and to receive and transmit
distributions of principal of and interest on the Book-Entry CitiCertificates.
Participants and Indirect Participants with which Beneficial Owners have
accounts with respect to the Book-Entry CitiCertificates similarly are required
to make book-entry transfers and receive and transmit such payments on behalf of
their respective Beneficial Owners.

     Beneficial Owners that are not Participants or Indirect Participants but
desire to purchase, sell or otherwise transfer ownership of, or other interests
in, Book-Entry CitiCertificates may do so only through Participants and Indirect
Participants. In addition, Beneficial Owners will receive all distributions of
principal and interest from the Trustee, or a paying agent on behalf of the
Trustee, through DTC Participants. DTC will forward such distributions to its
Participants, which thereafter will forward them to Indirect Participants or
Beneficial Owners. Beneficial Owners will not be recognized by the Trustee, the
Servicer or any paying agent as Certificateholders, as such term is used in the
Pooling Agreement, and Beneficial Owners will be permitted to exercise the
rights of Certificateholders only indirectly through DTC and its Participants.

     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a Beneficial
Owner to pledge Book-Entry CitiCertificates to persons or entities that do not
participate in the DTC system, or to otherwise act with respect to such
Book-Entry CitiCertificates, may be limited due to the lack of a physical
certificate for such Book-Entry CitiCertificates. In addition, under a
book-entry format, Beneficial Owners may experience delays in receipt of their
payments, since distributions will be made by the Servicer, or a paying agent on
behalf of the Servicer, to Cede, as nominee for DTC.

     DTC has advised the Issuer that it will take any action permitted to be
taken by a Certificateholder under the Pooling Agreement only at the direction
of one or more Participants to whose accounts with DTC the Book-Entry
CitiCertificates are credited. Additionally, DTC has advised the Issuer that it
will take such actions only at the direction of and on behalf of Participants
whose holdings of Book-Entry CitiCertificates evidence the corresponding
percentage of ownership interests. DTC may take conflicting actions to the
extent that Participants whose holdings of Book-Entry CitiCertificates evidence
such percentage of ownership interests authorize divergent action.

     Neither the Issuer, the Servicer nor the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of Book-Entry CitiCertificates held by
Cede, as nominee for DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

DEFINITIVE CERTIFICATES

     The Class A-14 CitiCertificates, the Class M CitiCertificates, the
Unoffered Class A-IO CitiCertificates, the Offered Class B CitiCertificates, the
Unoffered Class B CitiCertificates and the Residual Certificates will be issued
in fully registered, certificated form ("Definitive Certificates"). The
Book-Entry CitiCertificates will be issued as Definitive Certificates to
Beneficial Owners or their nominees, rather than to DTC or its nominee, only if
(i) the Servicer advises the Trustee in writing that DTC is no longer willing or
able to discharge properly its responsibilities


                                      S-75

<PAGE>

as depository with respect to the Book-Entry CitiCertificates and the Servicer
is unable to locate a qualified successor, (ii) the Servicer, at its option,
elects to terminate the book-entry system through DTC or (iii) after the
occurrence of a dismissal or resignation of the Servicer under the Pooling
Agreement, Beneficial Owners representing not less than 51% of the ownership
interests of each outstanding Subclass of Book-Entry CitiCertificates advise the
Trustee through DTC in writing that the continuation of a book-entry system
through DTC (or a successor thereto) is no longer in the Beneficial Owners' best
interest.

     Upon the occurrence of any event described in the preceding paragraph, the
Trustee will be required to notify all Beneficial Owners through Participants of
the availability of Definitive Certificates.

     Upon surrender by DTC of the definitive CitiCertificates representing the
Book-Entry CitiCertificates and receipt of instructions for re-registration, the
Trustee will reissue the Book-Entry CitiCertificates as Definitive Certificates
to Beneficial Owners. Distributions of principal of, and interest on, the
Book-Entry CitiCertificates will thereafter be made by the Trustee, or a paying
agent on behalf of the Trustee, directly to holders of Definitive Certificates
in accordance with the procedures set forth in the Pooling Agreement.

     Definitive Certificates will be transferable and exchangeable at the
offices of the Trustee. No service charge will be imposed for any registration
of transfer or exchange, but the Trustee may require payment of a sum sufficient
to cover any tax or other governmental charge imposed in connection therewith.

REPORTS TO CERTIFICATEHOLDERS

     Unless and until Definitive Certificates are issued in respect of the
Book-Entry CitiCertificates, monthly and annual reports containing information
concerning the Trust and prepared by the Servicer pursuant to the Pooling
Agreement will be sent to Cede as nominee of DTC and registered holder of the
Book-Entry CitiCertificates, as well as to holders of the Definitive
Certificates. The Pooling Agreement does not require the sending of any
financial reports to the Beneficial Owners. Beneficial Owners may obtain copies
of any Distribution Date statement free of charge upon request from the Servicer
at (314) 256-6406.

VOTING RIGHTS

     At all times, 97% of the voting rights of holders of the CitiCertificates
under the Pooling Agreement will be allocated among the Class A CitiCertificates
(other than the Class A-12 CitiCertificates), the Class M CitiCertificates and
the Class B CitiCertificates based upon such Class's pro rata interest in the
Trust. The holders of the Unoffered Class A-IO CitiCertificates will be
allocated 2% of such voting rights. The holders of the Class A-12
CitiCertificates will be allocated 1% of such voting rights. Voting rights will
be allocated among the Subclasses of the same Class (other than the Class A-12
CitiCertificates) in proportion to their percentage interest in such Class based
on their Stated Amounts (or notional amounts in the case of the Class A-12
CitiCertificates).

                      THE INSURANCE POLICY AND THE INSURER

     The following information has been supplied by MBIA Insurance Corporation
(the "Insurer") for inclusion in this Prospectus Supplement. A copy of the
Insurance Policy may be obtained from the Trustee upon request.

THE INSURANCE POLICY

     The Insurer in consideration of the payment of the premium and subject to
the terms of the Certificate Guaranty Insurance Policy (the "Insurance Policy")
thereby unconditionally and irrevocably guarantees to any Owner that an amount
equal to each full and complete Insured Payment will be received by the Trustee
or its successors, as trustee for the Owners, on behalf of the Owners from the
Insurer, for distribution by the Trustee to each Owner of each Owner's
proportionate share of the Insured Payment. The Insurer's obligations under the
Insurance Policy with respect to a particular Insured Payment shall be
discharged to the extent funds equal to the applicable Insured Payment are
received by the Trustee whether or not such funds are properly applied by the
Trustee. Insured Payments shall be made only at the time set forth in the
Insurance Policy, and no accelerated Insured Payments shall be made regardless
of any acceleration of the Class A-11 CitiCertificates, unless such acceleration
is at the sole option of the Insurer.


                                      S-76

<PAGE>

     Notwithstanding the foregoing paragraph, the Insurance Policy does not
cover shortfalls, if any, attributable to any liability of a REMIC, the Trust
Fund or the Trustee for withholding taxes, if any (including interest and
penalties in respect of any such liability). THE INSURANCE POLICY DOES NOT
PROVIDE CREDIT ENHANCEMENT FOR ANY CLASS OR SUBCLASS OF CITICERTIFICATES OTHER
THAN THE CLASS A-11 CITICERTIFICATES.

     The Insurer will pay any Insured Payment that is a Preference Amount on the
Business Day following receipt on a Business Day by the Fiscal Agent (as
described below) of (i) a certified copy of the order requiring the return of a
preference payment, (ii) an opinion of counsel satisfactory to the Insurer that
such order is final and not subject to appeal, (iii) an assignment in such form
as is reasonably required by the Insurer, irrecovably assigning to the Insurer
all rights and claims of the Owner relating to or arising under the Class A-11
CitiCertificates against the debtor which made such preference payment or
otherwise with respect to such preference payment and (iv) appropriate
instruments to effect the appointment of the Insurer as agent for such Owner in
any legal proceeding related to such preference payment, such instruments being
in a form satisfactory to the Insurer, provided that if such documents are
received after 12:00 noon New York City time on such Business Day, they will be
deemed to be received on the following Business Day. Such payments shall be
disbursed to the receiver or trustee in bankruptcy named in the final order of
the court exercising jurisdiction on behalf of the Owner and not to any Owner
directly unless such Owner has returned principal or interest paid on the Class
A-11 CitiCertificates to such receiver or trustee in bankruptcy, in which case
such payment shall be disbursed to such Owner.

     The Insurer will pay any other amount payable under the Insurance Policy no
later than 12:00 noon New York City time on the later of the Distribution Date
on which the related Deficiency Amount is due or the third Business Day
following receipt in New York, New York on a Business Day by State Street Bank
and Trust Company, N.A., as Fiscal Agent for the Insurer or any successor fiscal
agent appointed by the Insurer (the "Fiscal Agent") of a Notice (as described
below); provided that if such Notice is received after 12:00 noon New York City
time on such Business Day, it will be deemed to be received on the following
Business Day. If any such Notice received by the Fiscal Agent is not in proper
form or is otherwise insufficient for the purpose of making claim under the
Insurance Policy it shall be deemed not to have been received by the Fiscal
Agent for purposes of this paragraph, and the Insurer or the Fiscal Agent, as
the case may be, shall promptly so advise the Trustee and the Trustee may submit
an amended Notice.

     Insured Payments due under the Insurance Policy, unless otherwise stated
therein, will be disbursed by the Fiscal Agent to the Trustee on behalf of the
Owners by wire transfer of immediately available funds in the amount of the
Insured Payment less, in respect of Insured Payments related to Preference
Amounts, any amount held by the Trustee for the payment of such Insured Payment
and legally available therefor.

     The Fiscal Agent is the agent of the Insurer only and the Fiscal Agent
shall in no event be liable to Owners for any acts of the Fiscal Agent or any
failure of the Insurer to deposit or cause to be deposited, sufficient funds to
make payments due under the Insurance Policy.

     Upon and to the extent of any disbursement under the Insurance Policy, the
Insurer shall become the owner or holder of such right to payment and shall be
subrogated to the rights of the Owner to receive payments under the Class A-11
CitiCertificates to the extent of any payment by the Insurer under the Insurance
Policy.

     As used herein and in the Insurance Policy, the following terms shall have
the following meanings:

     "Agreement" means the Pooling and Servicing Agreement, dated as of July 1,

     "Business Day" means any day other than a Saturday, Sunday or a day on

(A) the sum of (i) the Class A Subclass Interest Shortfall Amount for such
Distribution Date for the Class A-11 CitiCertificates, (ii) any Non-Supported

CitiCertificates and not covered by the Reserve Fund and (iii) the amount of the
principal or interest portion of any Realized Losses for such Distribution Date
allocated to the Class A-11 CitiCertificates, including any Excess Special
Hazard Losses, Excess Fraud Losses or Excess Bankruptcy Losses (and excluding
Extraordinary Losses) and (B) for the Last Scheduled Distribution Date, the
Stated Amount of the Class A-11 CitiCertificates to the extent unpaid on the
Last Scheduled Distribution Date.

the Insurance Policy shall have the respective meanings set forth in the
Agreement as of the date of execution of such Insurance Policy, without giving

distributions made on the Class A-11 CitiCertificates prior to the effective
date of the cancellation of the Insurance Policy. The premium on the Insurance
Policy is not refundable for any reason including payment, or provision being
made for payment, prior to maturity of the Class A-11 CitiCertificates;
provided, however, that no premium on the Insurance Policy shall be due after

A-11 CitiCertificates. The Insurer does not guarantee the market price of the
Class A-11 CitiCertificates nor does it guarantee that the ratings on the Class
A-11 CitiCertificates will not be revised or withdrawn.

                              ERISA CONSIDERATIONS

     The Department of Labor has granted to the Senior Underwriter an
administrative exemption, Prohibited Transaction Exemption PTE 91-14 (the
"Exemption"), from certain of the prohibited transaction rules of ERISA and
certain of the excise taxes imposed by Section 4975 of the Code with respect to
the initial purchase, the holding, and the subsequent resale by ERISA Plans of
certificates in pass-through trusts that meet the conditions and requirements of
the Exemption. The Exemption should apply to the acquisition, holding, and
resale of the Offered Senior CitiCertificates by an ERISA Plan, provided that
specified conditions (certain of which are described below) are met.

     Among the conditions which must be satisfied for the Exemption to apply to
the acquisition by an ERISA Plan of the Offered Senior CitiCertificates are the
following: (1) the acquisition of the Offered Senior CitiCertificates by an
ERISA Plan is on terms (including the price for such CitiCertificates) that are
at least as favorable to the ERISA Plan as they would be in an arm's-length
transaction with an unrelated party; (2) the rights and interests evidenced by
the Offered Senior CitiCertificates acquired by the ERISA Plan are not
subordinated to the rights and interests evidenced by other certificates of the
Trust; (3) the Offered Senior CitiCertificates acquired by the ERISA Plan have
received a rating at the time of such acquisition that is in one of the three
highest generic rating categories from any of S&P, Fitch, Duff & Phelps Credit
Rating Co. or Moody's Investors Service, Inc.; (4) the sum of all payments made
to the Underwriter in connection with the distribution of the Offered Senior
CitiCertificates represents not more than reasonable compensation for
underwriting such CitiCertificates; and (5) the sum of all payments made to and
retained by the Servicer represents not more than reasonable compensation for
the Servicer's services under the Pooling Agreement and reimbursement of the
Servicer's reasonable expenses in connection therewith.

     In addition, it is a condition that the ERISA Plan investing in the Offered
Senior CitiCertificates be an "accredited investor" as defined in Rule 501(a)(1)
of Regulation D of the Commission under the Securities Act of 1933, as amended
(the "Securities Act").

     The Exemption does not apply to the acquisition and holding of Offered
Senior CitiCertificates by ERISA Plans sponsored by the Issuer, the Senior
Underwriter, the Trustee, the Servicer, or any affiliate of such parties.
Moreover, the Exemption provides relief from certain self-dealing/conflict of
interest prohibited transactions, only if, among other requirements (i) an ERISA
Plan's investment in each Class A Subclass of the Class A CitiCertificates does
not exceed 25% of that Class A Subclass outstanding at the time of the
acquisition and (ii) immediately after the acquisition, no more than 25% of the
assets of an ERISA Plan with respect to which the person who has discretionary
authority or renders advice are invested in certificates representing an
interest in a trust containing assets sold or serviced by the same person.

     A governmental plan as defined in Section 3(32) of ERISA is not subject to
ERISA or Code Section 4975. However, such a governmental plan may be subject to
a federal, state, or local law, which is, to a material extent, similar to the
provisions or ERISA or Section 4975 of the Code ("Similar Law"). A fiduciary of
a governmental plan should make its own determination as to the need for the
availability of any exemptive relief under Similar Law.

     Neither the Exemption nor PTE 83-1 (discussed under "ERISA Considerations"
in the Prospectus) applies to the acquisition or holding of the Class M
CitiCertificates or the Offered Class B CitiCertificates, which are subordinated
to the Class A and Unoffered Class A-IO CitiCertificates. Accordingly, no
transfer of an Offered Class B CitiCertificate or Class M CitiCertificate to a
Plan will be registered unless the transferee (i) executes a representation
letter in form and substance satisfactory to the Trustee stating that (a) it is
not, and is not acting on behalf of a Plan or using the assets of any such Plan
to effect such purchase or (b) if it is an insurance company, the source of
funds used to purchase Class M CitiCertificates or Offered Class B
CitiCertificates, as the case may be, is an "insurance company general account"
(as such term is defined in Section V(e) of Prohibited Transaction Class
Exemption 95-60 ("PTE 95-60"), 60 Fed. Reg. 35925 (July 12, 1995) and there is
no Plan with respect to which the amount of such general account's reserves and
liabilities for the contract(s) held by or on behalf of such Plan and all other
Plans maintained by the same employer (or affiliate thereof as defined in
Section V(a)(1) of PTE 95-60) or by


                                      S-80

<PAGE>

the same employee organization, exceed 10% of the total of all reserves and
liabilities of such general account (as such amounts are determined under
Section I(a) of PTE 95-60) at the date of acquisition or (ii) delivers (A) an
opinion of counsel in form and substance satisfactory to the Trustee and the
Issuer that the purchase or holding of the Class M CitiCertificates or Offered
Class B CitiCertificates by or on behalf of such Plan will not result in the
assets of the Trust being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA and the Code or Similar Law and will
not subject the Servicer (or its designee), the Issuer or the Trustee to any
obligation in addition to those undertaken in the Pooling Agreement and (B) such
other opinions of counsel, officers' certificates and agreements as the Trustee
and the Issuer may require in connection with such transfer.

     Fiduciaries that are investing or that could be deemed to be investing
assets of Plans should consult their legal advisors, and refer to the discussion
under "ERISA CONSIDERATIONS" in the Prospectus.

                                LEGAL INVESTMENT

     The Class A and Class M CitiCertificates will constitute "mortgage related
securities" for purposes of SMMEA, so long as they are rated in one of the two
highest rating categories by at least one nationally recognized statistical
rating organization. As "mortgage related securities," such CitiCertificates
will constitute legal investments for certain entities to the extent provided in
SMMEA. However, there are regulatory requirements and considerations applicable
to regulated financial institutions and restrictions on the ability of such
institutions to invest in certain types of mortgage related securities.

     THE OFFERED CLASS B CITICERTIFICATES WILL NOT CONSTITUTE "MORTGAGE RELATED
SECURITIES" FOR PURPOSES OF SMMEA.

     Prospective purchasers of the Offered CitiCertificates should consult their
own legal, tax and accounting advisors in determining the suitability of and
consequences to them of the purchase, ownership and disposition of the Offered
CitiCertificates. See "LEGAL INVESTMENT" in the Prospectus.

                              PLAN OF DISTRIBUTION

     Subject to the terms and conditions of the Underwriting Agreement among
Citicorp, the Issuer and the Senior Underwriter (the "Senior Underwriting
Agreement"), the Senior CitiCertificates are being purchased from the Issuer by
the Senior Underwriter upon issuance. The Senior Underwriter is committed to
purchase all of the Senior CitiCertificates if any CitiCertificates are
purchased. Subject to the terms and conditions of the Underwriting Agreement
among Citicorp, the Issuer and the Subordinated Underwriter (the "Subordinated
Underwriting Agreement" and, together with the Senior Underwriting Agreement,
the "Underwriting Agreements"), the Offered Subordinated CitiCertificates are
being purchased by the Subordinated Underwriter upon issuance. The Subordinated
Underwriter is committed to purchase all of the Offered Subordinated
CitiCertificates if any CitiCertificates are purchased. The closing of the sale
of the Senior CitiCertificates is a condition to the closing of the sale of the
Offered Subordinated CitiCertificates and vice versa. Distribution of such
Offered CitiCertificates is being made by the respective Underwriter from time
to time in negotiated transactions or otherwise at varying prices to be
determined at the time of sale. The Senior Underwriter has advised the Issuer
that Edward D. Jones & Co., L.P. (the "Dealer") also proposes to offer the Class
A-11 CitiCertificates, from time to time, in negotiated transactions or
otherwise at varying prices to be determined at the time of sale. Proceeds to
the Issuer will be approximately 98.68093% of the aggregate Initial Stated
Amount of the Class A CitiCertificates, approximately 98.69581% of the aggregate
Initial Stated Amount of the Class M CitiCertificates and approximately
97.05616% of the aggregate Initial Stated Amount of the Offered Class B
CitiCertificates, plus accrued interest as set forth on the front cover hereof
and before deducting expenses payable by the Issuer, provided that if the
aggregate Initial Stated Amount of the Class A CitiCertificates is less than
$290,561,770, the aggregate proceeds to the Issuer (stated as a percentage of
the aggregate Initial Stated Amount of the Class A CitiCertificates) will be
adjusted upwards by not more than 0.002% and if the aggregate Initial Stated
Amount of the Class A CitiCertificates is greater than $290,561,770, the
aggregate proceeds to the Issuer (stated as a percentage of the aggregate
Initial Stated Amount of the Class A CitiCertificates) will be adjusted
downwards by not more than 0.002%. In connection with the purchase and sale of
the Offered CitiCertificates, the Underwriters may be deemed to have received
compensation from the Issuer in the form of underwriting discounts.


                                      S-81

<PAGE>

     Subject to the terms and conditions of the purchase agreement among
Citicorp, the Issuer and Salomon Brothers Inc (the "Purchase Agreement"), the
Unoffered Class B CitiCertificates (not offered hereby) are being purchased by
Salomon Brothers Inc upon issuance. Salomon Brothers Inc is committed to
purchase all of the Unoffered Class B CitiCertificates if any Offered
CitiCertificates are purchased. The Unoffered Class B CitiCertificates will be
offered through Salomon Brothers Inc in one or more negotiated transactions, as
a private placement to a limited number of institutional investors. The closing
of the sale of the Unoffered Class B CitiCertificates under the Purchase
Agreement is a condition to the closing of the sale of the Offered
CitiCertificates to the Underwriter.

     The Underwriting Agreements provide that the Issuer and Citicorp will
indemnify the Underwriters against certain civil liabilities under the
Securities Act or contribute to payments the Underwriters may be required to
make in respect thereof.

     On April 5, 1998, Citicorp, of which the Issuer, CMI, CFSB and Citibank are
wholly owned subsidiaries, and Travelers Group Inc. ("Travelers"), of which
Salomon Brothers Inc is a wholly owned subsidiary, agreed to merge (the
"Merger"). The combined company will be known as Citigroup Inc. The Merger is
subject to customary closing conditions, including regulatory approvals and the
affirmative vote of a majority of the stockholders of each of Citicorp and
Travelers.

                                  LEGAL MATTERS

     Certain legal matters will be passed upon for the Issuer and Citicorp by
Stephen E. Dietz, as an Associate General Counsel of Citibank, N.A., and for the
Underwriters by Cadwalader, Wickersham & Taft, New York, New York. Certain
federal income tax matters will be passed upon for the Issuer by Rona Daniels,
Vice President and Tax Counsel for Asset Securitization of Citibank, N.A. Each
of Mr. Dietz and Ms. Daniels owns or has the right to acquire a number of shares
of common stock of Citicorp equal to less than .01% of the outstanding common
stock of Citicorp. Certain ERISA matters will be passed upon for the Issuer by
Cadwalader, Wickersham & Taft, New York, New York. Certain legal matters will be
passed upon for the Insurer by Kutak, Rock, Omaha, Nebraska.

                         REMIC PASS-THROUGH CERTIFICATES

     Citicorp Mortgage Securities, Inc. (the "Issuer") may sell from time to
time, on terms to be determined at the time of sale, one or more series (each, a
"Series") of certificates (the "Certificates") consisting of one or more classes
(each, a "Class") evidencing ownership interests in a trust (the "Trust"), to be
created by the Issuer, with respect to which one or more elections will be made
to treat such Trust, or one or more segregated pools of assets within such
Trust, as one or more real estate mortgage investment conduits (each, a "REMIC")
under the Internal Revenue Code of 1986, as it may be amended from time to time
(the "Code"). The property of each such REMIC will consist of a pool of assets
(for each Series, a "Pool"), or interests in another REMIC consisting of a Pool,
comprised primarily of mortgage loans or mortgage-backed certificates conveyed
to such Trust by the Issuer. Any Class of Certificates may be divided into two
or more subclasses (each, a "Subclass"). The Certificates will consist of one or
more Classes or Subclasses of regular interests (collectively, the
"CitiCertificates"), and of one Class or one Subclass of residual interests with
respect to each Pool (the "Residual Certificates"). Each Class or Subclass of
Certificates will evidence beneficial ownership of a specified percentage (which
may be 0%) or portion of future interest payments and a specified percentage
(which may be 0%) or portion of future principal payments on the Mortgage Loans
or Mortgage Certificates in the related Pool. One or more Classes or Subclasses
of CitiCertificates may be subject to deferred distribution of interest
("Accrual CitiCertificates"). If so specified in the applicable Prospectus
Supplement, a Series (a "Senior/Subordinated Series") may consist of one or more
Classes or Subclasses of Certificates subordinate in right of distributions (the
"Subordinated Certificates") to one or more other Classes or Subclasses (the
"Senior Certificates"). If so specified in the applicable Prospectus Supplement,
in addition to or in lieu of subordination, credit support may be provided for
any Class of Certificates in the form of a guaranty issued by Citicorp or
another guarantor (a "Guaranty"), letter of credit, mortgage pool insurance
policy or another form of credit support as described herein and in the
applicable Prospectus Supplement.

     The applicable Prospectus Supplement will set forth the specific terms of
each Class and/or Subclass of Certificates offered thereby, including (if
applicable) the aggregate initial Stated Amount, the Stated Rate and the Last
Scheduled Distribution Date for each such Class or Subclass; the terms of
distribution of accrued interest on any Class or Subclass of Accrual
CitiCertificates; the method used to calculate the aggregate amount of
distributions in reduction of Stated Amount of any Class or Subclass of
Certificates required to be made on each Distribution Date and the method of
allocation thereof; the Distribution Dates; the characteristics of the Mortgage
Loans or Mortgage Certificates comprising the Pool; whether more than one REMIC
election will be made; the terms of any special distributions or early
termination applicable to the Class or Subclass; the terms of any credit support
provided for a Class or Subclass; the terms of any subordination provided in a
Senior/Subordinated Series; the method of distribution of the Certificates; the
terms of any distributions on Residual Certificates; and other specific terms of
a Class or Subclass.

     Each Pool will consist of (i) fixed or adjustable interest rate mortgage
loans ("Mortgage Loans") (a portion of the interest on each such Mortgage Loan
may be retained by the Issuer or an affiliate of the Issuer) acquired by the
Issuer (a) from Citicorp Mortgage, Inc. ("CMI"), Citibank, N.A. ("Citibank") or
Citibank, Federal Savings Bank ("CFSB") or (b) from CitiMae, Inc. ("CitiMae") or
one of its affiliates or a seller-servicer approved by CitiMae or one of its
affiliates (collectively, the "CitiMae Originators") or (c) from another
affiliate of the Issuer specified in the applicable Prospectus Supplement
(collectively with CMI, Citibank and CFSB, the "Affiliated Originators") or (d)
from unaffiliated seller-servicers (the "Third Party Originators" and
collectively with the Affiliated Originators and the CitiMae Originators, the
"Originators"), (which Mortgage Loans may be acquired by CMI and then acquired
from CMI by the Issuer), (ii) mortgage-backed certificates previously issued by
the Issuer or an affiliate of the Issuer and described in the applicable
Prospectus Supplement ("Issuer Certificates"), (iii) certificates backed by
Mortgage Loans (together with Issuer Certificates, "CitiMortgageCertificates"),
and/or (iv) GNMA Certificates, FNMA Certificates and/or FHLMC Certificates (each
as defined herein, and collectively, together with CitiMortgageCertificates, the
"Mortgage Certificates"), together with certain other assets described herein or
as otherwise described in the Prospectus Supplement. The Mortgage Certificates
may be guaranteed as to payment of principal and interest to the extent
indicated herein and in the related Prospectus Supplement. The
CitiMortgageCertificates may have the benefit of credit support to the extent
provided herein and in the related Prospectus Supplement.

                           DESCRIPTION OF CERTIFICATES

GENERAL

     The Certificates are issuable in one or more Series. The Certificates of
each Series will evidence the entire beneficial ownership interest in the Trust
as to which one or more elections will be made to treat all or a specified
portion thereof (as specified in the related Prospectus Supplement) as one or
more REMICs as defined in Code Section 860D. The Trust will consist of (i) such
Mortgage Loans or Mortgage Certificates as from time to time are subject to the
Pooling Agreement; (ii) such funds or assets as from time to time are deposited
in the Certificate Account as described herein under APPENDIX A: "THE MORTGAGE
LOANS AND CITIMORTGAGECERTIFICATES --Payments on Mortgage Loans in Pools"; (iii)
property acquired by foreclosure or deed in lieu of foreclosure of Mortgage
Loans as from time to time are subject to the Pooling Agreement; (iv) any
combination of Guaranty, letter of credit, mortgage pool insurance policy, one
or more reserve funds and other form of credit support provided for such Series;
and (v) any title insurance policy and hazard insurance policy maintained with
respect to the Mortgaged Properties.

     Each Series will consist of one or more Classes or Subclasses of
CitiCertificates representing "regular interests" in one or more REMICs within
the meaning of Code Section 860G(a)(1) and one Class or one Subclass of Residual
Certificates representing the "residual interest" with respect to each REMIC
within the meaning of Code Section 860G(a)(2).

     Each Series of Certificates will consist of Residual Certificates and of
either (i) a single Class of CitiCertificates, (ii) two or more Classes of
CitiCertificates, one or more Classes or Subclasses (the "Senior Certificates")
of which will be senior in right of distributions to one or more of the other
Classes or Subclasses (the "Subordinated Certificates") to the extent described
in the related Prospectus Supplement (any such Series, a "Senior/Subordinated
Series"); (iii) two or more Classes or Subclasses of CitiCertificates which
differ as to the timing, sequential order, rate or amount of distributions of
principal or interest or both, or as to which distribution of principal or
interest or both on any Class or Subclass may be made upon the occurrence of
specified events, in accordance with a formula or schedule, or on the basis of
certain types of collections or from designated portions of the Pool, which
CitiCertificates may be Accrual CitiCertificates; or (iv) other types of Classes
or Subclasses of CitiCertificates as described in the related Prospectus
Supplement. Credit support for a Series of CitiCertificates may be provided by a
Guaranty, letter of credit, mortgage pool insurance policy, special hazard
insurance policy, bankruptcy bond, surety insurance policy or a Reserve Fund as
described herein and in the related Prospectus Supplement, or by the
subordination of one or more Classes or Subclasses of CitiCertificates or
Residual Certificates as described herein and in the related Prospectus
Supplement, or by any combination of the foregoing. See "DESCRIPTION OF
CERTIFICATES--Credit Support."

     The Issuer may sell certain Classes or Subclasses of Certificates of a
Series, including one or more Classes or Subclasses of Subordinated Certificates
or the Residual Certificates, by means of this Prospectus and a Prospectus
Supplement if, at the time of such sale, at least one nationally recognized
statistical rating organization has rated the Classes or Subclasses of
Certificates of such Series in one of its generic rating categories which
signifies investment grade. Typically, the four highest categories (within which
there may be subcategories or gradations indicating relative standing) signify
investment grade.

     The Issuer may sell certain Classes or Subclasses of Certificates of a
Series, including one or more Classes or Subclasses of Subordinated Certificates
or the one Class or one Subclass of Residual Certificates, in privately
negotiated transactions exempt from registration under the Securities Act of
1933, as amended (the "Securities Act").

     Unless otherwise specified in the related Prospectus Supplement, the
CitiCertificates of specified Classes or Subclasses of a Series will be issued
in the form of book entries on the records of The Depository Trust Company
("DTC") and participating members thereof.

     Interest distributions and distributions in reduction of the Stated Amount
with respect to Certificates of any Series will be made on the Distribution
Dates for such Series (i) by check mailed to holders of such Certificates
registered as such on the applicable Record Date at their addresses appearing on
the Certificate Register, (ii) upon written request of a Certificateholder to
the Trustee (or the paying agent), by wire transfer in immediately available
funds to the account of such Certificateholder provided that such
Certificateholder holds at least the minimum denomination specified in the
applicable Prospectus Supplement and Pooling Agreement, or (iii) by such other
means 

                                      4
<PAGE>

as are agreed upon by the paying agent and a Certificateholder; provided,
however, that distributions in reduction of Stated Amount which reduce the
Stated Amount of a Certificate to zero will be made only upon presentation and
surrender of such Certificate at the office or agency of any paying agent for
such Series, unless otherwise specified in the related Prospectus Supplement.
Notice will be mailed before the Distribution Date on which the final
distribution in reduction of Stated Amount on any Certificate is expected to be
made to the holder of such Certificate.

     The Trustee will include with each distribution on a CitiCertificate a
statement showing, among other things, the allocation of such distribution to
interest and reductions of Stated Amount and the remaining Stated Amount of a
CitiCertificate of each Class or Subclass of that Series in the minimum
denomination (or minimum permitted increment above such denomination, if less)
specified in the related Prospectus Supplement (a "Single Certificate"). On each
Distribution Date before a distribution is first made on a particular Class of
Accrual CitiCertificates, the Trustee will also furnish to each holder of an
Accrual CitiCertificate of such Class a statement showing (i) the interest
accrued during the Interest Accrual Period applicable to such Distribution Date,
(ii) the amount of accrued interest to be added to the Stated Amount thereof and
(iii) the Stated Amount of such an Accrual CitiCertificate after giving effect
to such addition to the Stated Amount thereof, in each case for an Accrual
CitiCertificate which is a Single Certificate. In the case of a Pool that
consists of Whole or Partial Pool Issuer Certificates, such statement will also
show the outstanding and initial principal amounts of each such Issuer
Certificate.

DISTRIBUTIONS TO CERTIFICATEHOLDERS

  General

     Beginning with the month next succeeding the month in which Certificates of
a Series are originally issued, distributions of principal and interest thereon
at the Stated Rate will be made on the 25th day of each month, or if such day is
not a business day, the immediately following business day (each, a
"Distribution Date"), or on such other date as may be specified in the related
Prospectus Supplement, to the persons in whose names the Certificates are
registered at the close of business on the last business day of the preceding
month, or such other date as may be specified in the related Prospectus
Supplement (the "Record Date"). Alternatively, if the related Prospectus
Supplement so provides, distributions will be made at quarterly, semi-annual or
other intervals, but at least annually. The amount of each distribution will be
determined on the 18th day of the month of the related Distribution Date or, if
such 18th day is not a business day, the immediately preceding business day
(each, a "Determination Date") or such other date as may be specified in the
related Prospectus Supplement.

     Unless otherwise specified in the related Prospectus Supplement,
distributions to Certificateholders of a Class or Subclass will be made pro rata
among Certificateholders of such Class or Subclass. The manner in which any
available credit support will be allocated among the Classes or Subclasses of
Certificates in a Series will be specified in the related Prospectus Supplement.

     Distributions in reduction of Stated Amount of and in respect of interest
on, the Certificates will be made by or on behalf of the Issuer out of, and only
to the extent of, funds available for such purpose (the "Pool Distribution
Amount") in the Certificate Account of the related Series. All distributions on
the Certificates of each Series will be made on each Distribution Date for such
Series from the Pool Distribution Amount in accordance with the terms described
herein and in the related Prospectus Supplement, and as specified in the related
Pooling Agreement.

     Unless otherwise specified in the related Prospectus Supplement, for each
Pool consisting of Mortgage Loans, the Pool Distribution Amount for a
Distribution Date will be equal to the aggregate of all previously undistributed
proceeds of payments on account of principal, including amounts received in
respect of credit support, if any, and any payments or other recovery of
principal on a Mortgage Loan which is received in advance of its scheduled due
date and is not accompanied by an amount as to interest representing scheduled
interest for any month subsequent to the month of prepayment (each, a "Principal
Prepayment"), and interest, including any payments made from any related buydown
subsidy account, in respect of the Mortgage Loans received and posted after the
Cut-Off Date and before the related Determination Date, except in each case:

     (i) payments which were due on or before the Cut-Off Date;

     (ii) any Principal Prepayment received during the month of distribution and
any related payments of interest representing interest for the month of
distribution or any portion thereof (which will be distributed the next month);

                                       5
<PAGE>


     (iii) payments which represent early receipt of scheduled payments of
principal and interest due on a date or dates subsequent to the first day of the
month of distribution;

     (iv) that portion of payments on account of interest (including payments
made from a buydown subsidy account established with respect to such Mortgage
Loans) on the Mortgage Loans in the Pool in excess of interest at the
Pass-Through Rate;

     (v) that portion of the proceeds of the liquidation of defaulted Mortgage
Loans which represents servicing compensation to the Issuer and is to be paid to
the Issuer from the related Certificate Account to the extent described in
APPENDIX A: "THE MORTGAGE LOANS AND CitiMortgageCertificates--Realization Upon
Defaulted Mortgage Loans"; and

     (vi) any other amount not to be included in the Pool Distribution Amount
pursuant to the related Pooling Agreement.

     Unless otherwise specified in the related Prospectus Supplement for each
Pool consisting of Mortgage Certificates, the Pool Distribution Amount for a
Distribution Date will equal all previously undistributed amounts received as
principal and interest on such Mortgage Certificates in accordance with their
terms on or prior to the related Determination Date (or, for
CitiMortgageCertificates, the Distribution Date).

  Distributions of Interest

     Unless otherwise specified in the related Prospectus Supplement, each Class
or Subclass of Certificates entitled to a distribution of interest will be
entitled to such interest at a per annum rate (the "Stated Rate") which may be
fixed or, subject to federal income tax requirements, may vary over the life of
the Certificates.

     Unless otherwise specified in the related Prospectus Supplement, each Class
or Subclass of Certificates of a Series, other than Accrual CitiCertificates, if
any, will be entitled to receive distributions in respect of interest on each
Distribution Date and will accrue interest on the outstanding Stated Amount of
each such Class or Subclass of Certificates at the Stated Rate (calculated on
the basis of a 360-day year of twelve 30-day months) and for the periods (each
an "Interest Accrual Period") specified in the Prospectus Supplement. Accrual
CitiCertificates will accrue interest as described above but such accrued
interest will not be distributed until the occurrence of the events specified in
the related Prospectus Supplement. Prior to such time, the interest accrued but
not distributed on the Accrual CitiCertificates will be added to the Stated
Amount thereof on each Distribution Date.

  Distributions in Reduction of Stated Amount

     Each Certificate entitled to distributions representing principal payments
on the Mortgage Loans or Mortgage Certificates included in the Pool underlying
such Series will have a "Stated Amount" which, at any time will equal the
maximum amount in respect of principal which the holder of such Certificate will
be entitled to receive out of the future cash flow on the Mortgage Loans or the
Mortgage Certificates, and out of other assets, if any, included in the Trust.
The Prospectus Supplement will specify the method by which the amount of
distributions in reduction of Stated Amount to be distributed to the
Certificateholders on each Distribution Date (the "Certificate Distribution
Amount") will be calculated and the manner in which the Certificate Distribution
Amount will be allocated among the Classes or Subclasses entitled to
distributions thereof. Distributions in reduction of the Stated Amount of
Certificates will be made on each Distribution Date to the holders of the
Certificates then entitled to receive such distributions until the aggregate
amount of distributions have reduced the Stated Amount of each Certificate of a
Class or Subclass to zero. The initial aggregate Stated Amount of all Classes or
Subclasses of a Series may equal the aggregate outstanding principal amount of
the related Mortgage Loans or Mortgage Certificates as of the applicable Cut-Off
Date and, for each Class or Subclass, will be specified in the related
Prospectus Supplement. Alternatively, the initial aggregate Stated Amount of all
Classes or Subclasses of a Series of Certificates may equal the initial
aggregate Pool Value of the related Mortgage Loans or Mortgage Certificates as
of the applicable Cut-Off Date.

     The aggregate "Pool Value" of the related Mortgage Loans or Mortgage
Certificates will be the Stated Amount of the Certificates of that Series that,
based on certain assumptions and regardless of any prepayments on such Mortgage
Loans or Mortgage Certificates, can be supported by either the future scheduled
payments on the Mortgage Loans included in the Pool or the mortgage loans
underlying the Mortgage Certificates included in the Pool (with interest
adjusted to the applicable Pass-Through Rate), or the proceeds of the Principal
Prepayment of such Mortgage Loans or mortgage loans underlying the Mortgage
Certificates, together with reinvestment income, if any, thereon at 

                                       6
<PAGE>

the rate and for the period specified in the related Prospectus Supplement and,
if applicable, amounts available to be withdrawn from any Reserve Fund for such
Series, as further or otherwise specified in the related Prospectus Supplement.
In calculating Pool Values of Mortgage Certificates and Mortgage Loans included
in the Pool, future distributions on a Mortgage Loan will be determined based on
future scheduled payments (after giving effect to any Principal Prepayments
previously received and posted) on such Mortgage Loan, and future distributions
on a Mortgage Certificate will be determined either as if the underlying
mortgage loans constituted a single mortgage loan having the highest mortgage
rate and longest maturity of any mortgage loan underlying such Mortgage
Certificate or separately for each mortgage loan underlying such Mortgage
Certificate. Any similar Mortgage Loans or mortgage loans underlying Mortgage
Certificates or any Mortgage Certificates that are backed by the same pool of
mortgage loans, or similar pools of mortgage loans, may be aggregated into one
or more groups (each, a "Pool Value Group"), each of which will be assigned an
aggregate Pool Value calculated as if all such Mortgage Loans or mortgage loans
in, or all mortgage loans underlying all the Mortgage Certificates in, the Pool
Value Group constituted a single mortgage loan having the highest mortgage rate
and longest maturity of any such mortgage loan for such Pool Value Group. There
are a number of alternative means of determining the Pool Values of a Mortgage
Certificate, Mortgage Loan or Pool Value Group, including determinations based
on the discounted present value of the remaining scheduled distributions thereon
and determinations based on the relationship between the Pass-Through Rates
borne thereby and the Stated Rates of the related Series of Certificates.

     With respect to any Series as to which the initial Stated Amount of the
Certificates is calculated on the basis of the Pool Values of the Mortgage Loans
or the Mortgage Certificates, the Prospectus Supplement for each such Series
will describe the method or methods (and related assumptions) used to determine
the Pool Value of the Mortgage Certificates and Mortgage Loans or the Pool Value
Groups securing such Series. In any event, the aggregate of the Pool Values of
all the Mortgage Certificates and Mortgage Loans and all the Pool Value Groups
included in the Pool for a Series of Certificates will always be at least equal
to the aggregate Stated Amount of the Certificates of such Series. The
Certificate Distribution Amount with respect to a Series as to which the initial
Stated Amount of the Certificates is calculated on the basis of the Pool Values
of the Mortgage Loans or the Mortgage Certificates will generally be calculated
on the basis of the decline in the aggregate Pool Values of the Mortgage Loans
or Mortgage Certificates included in the Pool during the related Due Period, or
as otherwise described in the related Prospectus Supplement.

     The Stated Amount of a Certificate will decline as a result of
distributions attributable to principal that are made to the holders of the
Certificates and, to the extent described herein and in the related Prospectus
Supplement, as a result of losses on the Mortgage Loans or Mortgage Certificates
in the related Pool, to the extent that the credit support (including the amount
of subordination provided to Senior Certificates in a Senior/Subordinated
Series) provided for such Class or Subclass of Certificate is inadequate to
cover such losses. The Stated Amount of a Certificate may increase in the case
of Accrual CitiCertificates by interest accrued but not then distributable on
such Accrual CitiCertificates, and, to the extent that a Pool consists of
adjustable rate mortgages which provide for limitations on the amount by which
monthly payments by a Mortgagor may be increased and changes in the interest
rate on the Mortgage Loan are made more frequently than changes in the payment,
if an increase in the interest rate on the Mortgage Loan is not covered by the
amount of the related scheduled monthly payment.

     The aggregate amount which will be distributed in reduction of Stated
Amount to holders of CitiCertificates of each Series then entitled thereto on
any Distribution Date for such Series will equal, to the extent funds are
available, the sum of (i) the aggregate Certificate Distribution Amount, (ii)
the amount of interest, if any, accrued on any Accrual CitiCertificates of such
Series during the related Interest Accrual Period but not then required to be
distributed, such amount being added to the Stated Amount thereof, (iii) the
applicable percentage of the Spread, if any, specified in the Prospectus
Supplement and (iv) any amounts in reduction of Stated Amount previously
distributable but not yet distributed.

     Unless otherwise specified in the related Prospectus Supplement, in the
case of CitiCertificates of any Series consisting of more than one Class, if the
Amount Available under the credit support (including the amount of any
subordination provided to Senior Certificates in a Senior/Subordinated Series)
provided for such Series is inadequate to cover any loss on the Mortgage Loans
with the result that there are insufficient funds on deposit in the Certificate
Account on the next succeeding Distribution Date to pay the amount then
distributable to any Class of CitiCertificates then entitled to receive
distributions in reduction of Stated Amount (a "Loss Allocation Event"), then
the amount then available for distribution in reduction of Stated Amount on such
Distribution Date and each subsequent 

                                       7
<PAGE>

Distribution Date will be distributed on such Distribution Date pro rata to the
holders of CitiCertificates of a Class then outstanding notwithstanding any
priorities among Subclasses of such Class of CitiCertificates set forth in the
related Prospectus Supplement and pro rata to the holders of each Class of
CitiCertificates based on the outstanding Stated Amount of all Classes of
CitiCertificates then outstanding. Unless otherwise specified in the related
Prospectus Supplement, any shortfalls of interest will be allocated on a pro
rata basis based on the amount of interest then distributable (or allocable, in
the case of each Class of Accrual CitiCertificates) to each Class. On or after
the Distribution Date on which a Loss Allocation Event occurs, the Stated Amount
of all Classes then outstanding will be reduced on a pro rata basis, or as
otherwise specified in the related Prospectus Supplement, by the amount of any
losses actually incurred with respect to the Mortgage Loans.

     Funds available for distribution from the Certificate Account on a
Distribution Date will include distributions on Mortgage Certificates in the
Pool received in the related Due Period and payments received with respect to
Mortgage Loans in the Pool in the related Due Period, as described herein. See
APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Payments on
Mortgage Loans in Pools." Amounts remaining in the Certificate Account which are
available for distribution, as so described, after payment of all amounts due to
holders of CitiCertificates, and after payment of certain expenses therefrom,
will be distributed to holders of Residual Certificates on a pro rata basis.

     The "Spread" with respect to a Distribution Date for a Series will be the
excess of (a) the sum of (i) all distributions received on the Mortgage
Certificates or Mortgage Loans (net of (1) any Servicing Compensation, and (2)
in the case of Mortgage Loans, any distributions on such Mortgage Loans
representing the receipt of (A) scheduled payments of principal and interest due
on a date subsequent to the period (a "Due Period") beginning at the close of
business on the last day of the preceding Due Period (or, in the case of the
first Due Period, beginning at the close of business on the Cut-Off Date) and
ending at the close of business on the business day preceding the Determination
Date in respect of such Distribution Date, and (B) Principal Prepayments
received during the month of the applicable Determination Date) included in the
Pool for such Series in the Due Period preceding such Distribution Date, and, in
the case of the first Due Period, any amount deposited in the Certificate
Account on the Closing Date, (ii) income from reinvestment, if any, of such net
distributions and any amount on deposit in the Reserve Fund and (iii) to the
extent specified in the related Prospectus Supplement, the amount of cash
withdrawn from any Reserve Fund or buydown subsidy account since the preceding
Distribution Date for such Series (or since the Closing Date in the case of the
first Distribution Date for such Series) and required to be deposited in the
Certificate Account for such Series, over (b) the sum of (i) all interest
distributed on the CitiCertificates of such Series or added to the Stated Amount
of the Accrual CitiCertificates of such Series on such Distribution Date, (ii)
the aggregate Certificate Distribution Amount for such Series with respect to
such Distribution Date, (iii) if applicable to such Series, any Special
Distributions in respect of such Series made since the preceding Distribution
Date for such Series (or since the Closing Date in the case of the first
Distribution Date for such Series), (iv) any reimbursements of payments under
any credit support for such Series or Voluntary Advances with respect to such
Distribution Date, (v) any amounts paid to the issuer of credit support and (vi)
any REMIC Servicing Fee payable during the Due Period preceding such
Distribution Date.

     Series of CitiCertificates having other than monthly Distribution Dates may
receive special distributions ("Special Distributions") with respect to any
period for which distributions are received on the related Mortgage Loans or
Mortgage Certificates, other than such periods which include Distribution Dates,
if, as a result of principal prepayments on the mortgage loans underlying the
Mortgage Certificates or on the Mortgage Loans in the Pool for such Certificates
or low reinvestment yields, or both, the Trustee determines, based on
assumptions as to timing of receipt of distributions, reinvestment income and
prepayment rates, among others, specified in the Pooling Agreement, that the
amount of cash anticipated to be on deposit in the Certificate Account for such
Series on the earlier of the next Distribution Date or the second succeeding
Distribution Date for such Series may be less than the sum of interest
distributions and distributions in reduction of Stated Amount that would be made
on such date if it were a Distribution Date. Special Distributions on the
CitiCertificates of a Series will be allocated in the same manner as would
distributions on the next Distribution Date for such Series. 

CREDIT SUPPORT

  General

     Credit support may be provided with respect to one or more Classes or
Subclasses of CitiCertificates or with respect to the assets in the related
Trust. Credit support may be in the form of the subordination of one or more
Classes 

                                       8
<PAGE>

or Subclasses of CitiCertificates of such Series to one or more other Classes or
Subclasses of CitiCertificates, a limited guaranty issued by Citicorp or another
guarantor, a letter of credit, a mortgage pool insurance policy, a special
hazard insurance policy, a bankruptcy bond, a surety policy, the establishment
of one or more reserve funds or any other form of credit support described in
the applicable Prospectus Supplement, or any combination of the foregoing.
Unless otherwise specified in the Prospectus Supplement, credit support will not
provide protection against all risks of loss and will not guarantee repayment of
the entire Stated Amount of the CitiCertificates and interest thereon. If losses
occur which exceed the amount covered by credit support or are of a type which
are not covered by the credit support, holders of the CitiCertificates will bear
their allocable share of such deficiencies as described in the related
Prospectus Supplement.

  Subordination

     If so specified in the related Prospectus Supplement, credit support for
one or more Classes or Subclasses of Senior Certificates in a
Senior/Subordinated Series may include one or more Classes or Subclasses of
Subordinated Certificates, such that distributions in respect of Scheduled
Principal, Principal Prepayments, interest or any combination thereof that
otherwise would have been payable to one or more Classes or Subclasses of
Subordinated Certificates will instead be payable to holders of one or more
Classes or Subclasses of Senior Certificates under the circumstances and to the
extent specified in the related Prospectus Supplement. Such subordination
provisions will have the effect of accelerating the amortization of the Senior
Certificates and increasing the respective percentage ownership interest
evidenced by the Subordinated Certificates in the related Trust, as well as
preserving the availability of the subordination provided by the Subordinated
Certificates.

     If so specified in the related Prospectus Supplement, delays in receipt of
Scheduled Principal and losses on defaulted Mortgage Loans or mortgage loans
underlying the Mortgage Certificates will be borne first by the various Classes
or Subclasses of Subordinated Certificates under the circumstances and subject
to the limitations specified in the related Prospectus Supplement, which will
have the effect of increasing the respective percentage ownership interest of
the Senior Certificates in the Trust. The aggregate distributions in respect of
delinquent Scheduled Principal and the aggregate losses in respect of defaulted
Mortgage Loans or mortgage loans underlying Mortgage Certificates which must be
borne by each Class or Subclass of Subordinated Certificates at any one time or
over the lives of the Certificates by virtue of the subordination and the amount
of the distributions otherwise distributable to the Subordinated
Certificateholders that will be distributable to the Senior Certificateholders
on any Distribution Date may be limited as specified in the Prospectus
Supplement (the "Subordination Amount"). If the aggregate distributions in
respect of delinquent Scheduled Principal and/or the aggregate losses in respect
of defaulted Mortgage Loans or mortgage loans underlying Mortgage Certificates
were to exceed the total amounts payable and available for distribution to the
Subordinated Certificateholders or, if applicable, were to exceed the specified
maximum Subordination Amount, holders of the Senior Certificates could
experience losses.

     The protection afforded to the Senior Certificateholders by the
preferential right of the Senior Certificateholders to receive current
distributions from the Pool may be enhanced to the extent specified in the
related Prospectus Supplement by the establishment and maintenance of one or
more reserve accounts (each a "Subordination Reserve Fund") funded by the
retention of all or any portion of distributions otherwise distributable to the
holders of the Subordinated Certificates on any Distribution Date, by all or a
portion of the Spread and/or by an initial deposit of the Issuer. Unless
otherwise specified in the related Prospectus Supplement, the Subordination
Reserve Fund will be included in the Trust. If specified in the Prospectus
Supplement relating to a Series of Certificates, the Subordination Reserve Fund
may be funded in any other manner acceptable to the rating agencies rating the
Series of Certificates and consistent with an election to treat the Trust (or
one or more segregated pools of assets therein) for such Series as one or more
REMICs (as the case may be).

     Eligible Investments for monies deposited in the Subordination Reserve Fund
will be specified in the applicable Pooling Agreement and, unless otherwise
provided in the related Prospectus Supplement, will mature no later than the
next Distribution Date.

     Holders of Subordinated Certificates of a Series will not be required to
refund any amounts which have been properly distributed to them, regardless of
whether there are sufficient funds to distribute to Senior Certificateholders
the amounts to which they are later entitled.

                                       9

  Limited Guaranty

     If so specified in the Prospectus Supplement relating to a Series of
Certificates, credit support may be provided by a Guaranty of Citicorp or
another guarantor specified in such Prospectus Supplement. The coverage, amount
and frequency of any reduction in coverage provided by a Guaranty issued with
respect to a Series of Certificates will be set forth in the Prospectus
Supplement relating to such Series.

  Letter of Credit

     If so specified in the Prospectus Supplement relating to a Series of
Certificates, credit support may be provided by the issuance of a letter of
credit by the bank or financial institution specified in the applicable
Prospectus Supplement. The coverage, amount and frequency of any reduction in
coverage provided by a letter of credit issued with respect to a Series of
Certificates will be set forth in the Prospectus Supplement relating to such
Series.

  Reserve Fund

     If so specified in the Prospectus Supplement relating to a Series of
Certificates, a reserve fund (the "Reserve Fund") may be established with the
Trustee by the Issuer. The manner of the funding of the Reserve Fund and the
amount required from time to time to be on deposit therein will be set forth in
the Prospectus Supplement.

  Pool Insurance Policies

     If so specified in the Prospectus Supplement relating to a Series of
Certificates, the Issuer will obtain a pool insurance policy for the Mortgage
Loans in the related Pool. The pool insurance policy will cover any loss
(subject to the limitations described in a related Prospectus Supplement) by
reason of default to the extent a related Mortgage Loan is not covered by any
primary mortgage insurance policy. The amount and principal terms of any such
coverage will be set forth in the Prospectus Supplement.

  Special Hazard Insurance Policies

     If so specified in the related Prospectus Supplement, for each Series of
Certificates as to which a pool insurance policy is provided, the Issuer will
also obtain a special hazard insurance policy for the related Pool in the amount
set forth in such Prospectus Supplement. The special hazard insurance policy
will, subject to the limitations described in the applicable Prospectus
Supplement, protect against loss by reason of damage to Mortgaged Properties
caused by certain hazards not insured against under the standard form of hazard
insurance policy for the respective states in which the Mortgaged Properties are
located. The amount and principal terms of any such coverage will be set forth
in the Prospectus Supplement.

  Mortgagor Bankruptcy Bond

     If so specified in the applicable Prospectus Supplement, losses resulting
from a bankruptcy proceeding relating to a mortgage affecting the Mortgage Loans
in a Pool with respect to a Series of Certificates will be covered under a
mortgagor bankruptcy bond (or any other instrument that will not result in a
downgrading of the rating of the Certificates of a Series by the rating agency
or rating agencies that rated such Series). Any mortgagor bankruptcy bond or
such other instrument will provide for coverage in an amount meeting the
criteria of the rating agency or rating agencies rating the Certificates of the
related Series. The amount and principal terms of any such coverage will be set
forth in the related Prospectus Supplement.

  Draws Under Credit Support Other Than Subordination

     The obligation of the issuer of credit support to make payments under such
credit support for the benefit of holders of Certificates shall be limited at
any time to the amount available (the "Amount Available") at such time. The
initial Amount Available shall be equal to the percentage specified in the
Prospectus Supplement of the aggregate Adjusted Balance of the related Mortgage
Loans as of the applicable Cut-Off Date (the "Credit Support Percentage"). The
Amount Available to be paid under any credit support may be subject to reduction
commencing at the times and in the amounts described in the applicable
Prospectus Supplement and Pooling Agreement. In addition, the Amount Available
to be paid under any credit support for losses or delinquencies arising from
certain causes may be limited to the extent set forth in the related Prospectus
Supplement. To the extent set forth in the applicable Prospectus Supplement and
in the event that more than one series of CitiMortgageCertificates underlies a
Series of Certificates, credit support may cover two or more of the series of
such CitiMortgageCertificates. This may be accomplished by the credit support on
the individual series of CitiMortgageCertificates being consolidated or by

                                       10
<PAGE>

credit support which relates to more than one of the series of
CitiMortgageCertificates and provides coverage for all such series of
CitiMortgageCertificates up to the Credit Support Percentage specified in the
Prospectus Supplement of the aggregate Adjusted Balance of the Mortgage Loans
underlying such CitiMortgageCertificates.

     The Issuer or the Servicer will be required to determine as of each
Determination Date whether a payment under any credit support will be necessary
on the next Distribution Date. The Issuer or the Servicer will advise the
Trustee of such determination and make a demand for payment under the credit
support to the issuer of credit support in accordance with the provisions of the
credit support and the applicable Pooling Agreement, as described in the related
Prospectus Supplement. The proceeds of such payments under the credit support
will be deposited into the Certificate Account. Unless otherwise specified in
the related Prospectus Supplement, payments received under the credit support
will be applied first to reimburse Voluntary Advances.

     Payments made by an issuer of credit support pursuant to its obligations
under the credit support to cover delinquencies will be allocated on a
loan-by-loan basis to specific Mortgage Loans, and the payments will be
reimbursed, as the specific Mortgagors make their delinquent payments, by
monthly withdrawals from the Certificate Account as such delinquent installments
are received. Remaining obligations under the credit support will be increased
as such payments are reimbursed. In addition, payments made under the credit
support to cover amounts in respect of interest distributed (but not received)
with respect to Principal Prepayments will be reimbursed to the issuer of credit
support from Servicing Compensation otherwise payable to the Issuer or the
Servicer. The credit support will be increased to the extent of such
reimbursement.

     If any Mortgage Loans become Liquidating Loans, the issuer of credit
support may, if so specified in the related Prospectus Supplement, be obligated
to purchase from the Trustee such Liquidating Loans up to the amount of the
remaining obligation under the credit support. The Servicer may make an advance
of a payment (a "Purchase Amount Advance") in respect of a Liquidating Loan on
behalf of the issuer of credit support in order to avoid demands or draws under
such credit support. If at any time the issuer of credit support makes a payment
or the Servicer makes a payment on its behalf in the amount of the full
outstanding principal balance of and accrued interest on a Liquidating Loan
(less any unreimbursed payments previously made under the credit support in
respect of such Liquidating Loan), the issuer of credit support (or its
designee) will be entitled to receive an assignment of such Liquidating Loan,
and the issuer of credit support (or such designee) will thereafter own such
Liquidating Loan free of any further obligation with respect thereto. Payments
made with respect to such a Liquidating Loan will be reimbursed only from the
proceeds (net of liquidation costs) of such Liquidating Loan. The remaining
obligations under the credit support will be increased to the extent such
payments are so reimbursed. To the extent the proceeds of liquidation of any
Liquidating Loan acquired by the issuer of credit support in the manner
described in this paragraph exceed the amount of payments made with respect
thereto, in the case of a Guaranty issued by Citicorp, Citicorp will be entitled
to retain such proceeds and in the case of other credit support, the Servicer
will be entitled to such proceeds unless otherwise specified in the related
Prospectus Supplement.

     The term "Liquidating Loan" means: (a) each Mortgage Loan with respect to
which foreclosure proceedings have been commenced (and the Mortgagor's right of
reinstatement or redemption has expired), (b) each Mortgage Loan with respect to
which the Issuer or the Servicer has agreed to accept a Transfer Instrument in
lieu of foreclosure and in whole or partial satisfaction of the Mortgage Loan,
and, if the Pool contains Cooperative Loans, Liquidating Loan will mean not only
each Cooperative Loan as to which (a) or (b) is applicable but also (c) each
Cooperative Loan with respect to which none of the interest or principal
installments which became due and payable during the previous six months have
been paid and (d) each Cooperative Loan with respect to which a court of
competent jurisdiction has entered a final judgment reducing the scheduled
monthly principal or interest installment payable on such Cooperative Loan. See
APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Realization Upon
Defaulted Mortgage Loans."

     If any Mortgage Loans become Liquidated Loans, the issuer of credit support
may, if so specified in the Prospectus Supplement be obligated to pay the amount
of any loss on such Liquidated Loan up to the amount of the remaining obligation
under the credit support. The amount of any loss on a Liquidated Loan is equal
to the excess of (a) the unpaid principal balance of such Liquidated Loan plus
accrued interest thereon over (b) the liquidation proceeds, net of liquidation
expenses, received with respect thereto. In the event that the amount of such a
loss is not covered, in whole or in part, by any credit support, the loss will
be allocated among the Certificates as specified in the related Prospectus
Supplement.

                                       11
<PAGE>

     The term "Liquidated Loan" means a Mortgage Loan with respect to which the
related Mortgaged Property has been acquired, liquidated or foreclosed and with
respect to which the Servicer or the Master Servicer, as the case may be,
determines that all liquidation proceeds which it expects to recover have been
recovered, or a Mortgage Loan with respect to which the related Mortgaged
Property is retained or sold by the Mortgagor and for which the Servicer or the
Master Servicer, as the case may be, has accepted payment from the Mortgagor in
consideration for the release of the Mortgage in an amount which is less than
the outstanding principal balance of such Mortgage Loan as a result of a
determination by the Servicer or the Master Servicer, as the case may be, that
the potential liquidation expenses with respect to such Mortgage Loan would
exceed the amount by which the cash portion of such payment is less than the
outstanding principal balance of such Mortgage Loan. See APPENDIX A: "THE
MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Realization Upon Defaulted Mortgage
Loans."

     Prospective purchasers of Certificates must, in the event of default by
Mortgagors, look to the credit of the issuer of credit support, to the extent of
its obligations under the credit support. If the Amount Available under a credit
support is exhausted, the Certificateholders of the related Series will bear all
risks of delinquency and loss resulting from defaults by Mortgagors (including
losses not covered by primary mortgage insurance) and from hazard losses not
covered by the standard hazard insurance policies required to be maintained by
the Mortgagors, and the Certificateholders must look primarily to the value of
the properties securing defaulted Mortgage Loans for recovery of the outstanding
principal and unpaid interest. See APPENDIX A: "THE MORTGAGE LOANS AND
CITIMORTGAGECERTIFICATES--Certain Legal Aspects of the Mortgage Loans." None of
the issuer of any credit support, the Issuer nor the Servicer intends to advance
its own funds with respect to any Series of Certificates or series of
CitiMortgageCertificates, except (i) in the case of the issuer of credit
support, to the limited extent of its obligations under such credit support and
(ii) in the case of the Issuer or the Servicer, in certain circumstances
involving recoverable costs of restoration of damaged property, as described
under APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Realization
Upon Defaulted Mortgage Loans," and certain other costs as described therein
under "--Servicing and Other Compensation and Payment of Expenses," and to make
Voluntary Advances to the extent set forth in the related Prospectus Supplement.

LAST SCHEDULED DISTRIBUTION DATE

     The "Last Scheduled Distribution Date" for each Class of CitiCertificates
of a Series is the latest date on which (based on the assumptions set forth in
the related Prospectus Supplement) the Stated Amount of such Class is expected
to be reduced to zero. Since the rate of distributions in reduction of Stated
Amount for each Series will depend on, among other things, the rate of payment
(including prepayments) of the principal of the mortgage loans (which include,
for purposes of this subsection, Mortgage Loans included directly in the Pool
and mortgage loans underlying Mortgage Certificates) in the Pool for such
Series, the actual last Distribution Date for any Class of CitiCertificates
could occur significantly earlier than its Last Scheduled Distribution Date.

     The rate of payments on the Mortgage Loans in the Pool for any Series will
depend on their particular characteristics, as well as on the prevailing level
of interest rates from time to time and other economic factors, and no assurance
can be given as to the actual prepayment experience of such mortgage loans. See
APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Prepayment
Experience."

     Weighted average life refers to the average amount of time that will elapse
from the date of issuance of a Certificate until the Stated Amount of such
Certificate has been reduced to zero. The weighted average life of the
Certificates of a Series will be influenced by, among other things, the rate at
which principal on the mortgage loans (which include, for purposes of this
subsection, Mortgage Loans included directly in the Pool and mortgage loans
underlying Mortgage Certificates) underlying or included in the Pool for such
Certificates is paid, which may be in the form of scheduled amortization or
prepayments (including prepayments and liquidations due to default, casualty,
receipt of insurance proceeds, condemnation and the like).

     Prepayments on mortgage loans are commonly measured relative to a
prepayment standard or model. Each Prospectus Supplement for CitiCertificates of
any Series consisting of more than one Class of CitiCertificates will describe
the payment standard or model used for the related Series and will contain
tables setting forth the projected weighted average life of each Class of
CitiCertificates of such Series and, to the extent distributions are not made
pro rata among all Classes of CitiCertificates of such Series, the percentage of
the Initial Stated Amount of each Class of CitiCertificates of such Series that
would be outstanding on specified Distribution Dates for such Series based on
the assumptions stated in such Prospectus Supplement, including assumptions that
prepayments on the mortgage loans 

                                       12
<PAGE>

underlying or included in the Pool are made at rates corresponding to various
percentages of the prepayment standard or model specified in such Prospectus
Supplement.

     There is, however, no assurance that prepayment of mortgage loans
underlying or included in the Pool for any Series of Certificates will conform
to any prepayment standard or model. The rate of principal prepayments on pools
of mortgage loans is influenced by a variety of economic, geographic, social and
other factors. In general, however, if prevailing interest rates fall
significantly below the interest rates on the mortgage loans underlying or
included in the Pool for a Series of Certificates, such mortgage loans are
likely to be the subject of higher principal prepayments than if prevailing
rates remain at or above the rates borne by such mortgage loans. It should be
noted that certain Mortgage Certificates included in a Pool for a Series of
Certificates may be backed by mortgage loans with different interest rates.
Accordingly, the prepayment experience of these Mortgage Certificates will to
some extent be a function of the mix of interest rates of the mortgage loans
underlying such Mortgage Certificates. Furthermore, the stated pass-through rate
of certain Mortgage Certificates may be two or more percentage points less than
the Note Rates of the underlying mortgage loans. Other factors affecting
prepayment of mortgage loans include changes in mortgagors' housing needs, job
transfers, unemployment, mortgagors' net equity in the properties securing the
mortgage loans and servicing decisions. 

RESIDUAL CERTIFICATES

     The Residual Certificates will represent "residual interests" in a REMIC
within the meaning of Code Section 860G(a)(2). See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES." A Class of Residual Certificates with respect to a Pool will be
issued simultaneously with the CitiCertificates of a Series. Such Residual
Certificates may be sold together with or separately from such CitiCertificates
or may be retained, in whole or in part, by the Issuer or the related
Originators and will represent the right to receive distributions as specified
in the related Prospectus Supplement. In addition, at such time as the Stated
Amount of each Class of CitiCertificates of such Series has been reduced to
zero, the holders of the Residual Certificates will be the sole owners of each
Pool and will have sole rights with respect to the Mortgage Certificates,
Mortgage Loans and other assets included in such Pool, including the right to
liquidate such Pool. 

THE SERVICER

     For each Series of Certificates, the Issuer will act as servicer (in such
capacity, the "Servicer" or "servicer") with respect to Mortgage Loans
purchased, directly or indirectly, by the Trust from CMI, Citibank or CFSB or
their affiliates (the "Affiliated Originators" and such Mortgage Loans being
herein referred to as "Affiliated Mortgage Loans") and, as master servicer (in
such capacity, the "Servicer" or "master servicer") with respect to Mortgage
Loans purchased, directly or indirectly, by the Trust (a) from CitiMae or its
affiliates who purchased such mortgage loans from seller-servicers approved by
CitiMae or from such seller-servicers ("CitiMae Originators" and such Mortgage
Loans being herein referred to as "CitiMae Mortgage Loans"), or (b) from Third
Party Originators, and will perform such functions as are described in the
Pooling Agreement. The Issuer may delegate any of its duties under the Pooling
Agreement to any corporation, including a corporation more than 50% of the stock
of which is owned, directly or indirectly, by Citicorp. Unless otherwise
disclosed in the related Prospectus Supplement, if the Mortgage Loans are
included directly in the Pool, the Issuer intends to subcontract its duties as
servicer with respect to the Affiliated Mortgage Loans to CMI (or its designated
subservicer) and its duties as master servicer (a) with respect to the CitiMae
Mortgage Loans, to CitiMae and (b) with respect to Mortgage Loans originated by
Third Party Originators ("Third Party Loans") and sold by them on a
servicing-retained basis, to a designated master servicer to be determined. Such
delegation does not relieve the Issuer of its responsibility with respect to
such duties. The Trustee may remove the servicer for failure to perform any of
its duties under the Pooling Agreement if such failure continues unremedied for
60 days after written notice from the Trustee. The Issuer may not resign from
its obligations and duties as servicer under the Pooling Agreement except upon
the determination, evidenced by an opinion of counsel, that its performance of
such duties is no longer permissible under applicable law, or with the consent
of the Trustee and of the holders of 662 @ 3% of outstanding Certificates. The
servicer will be entitled to servicing compensation for each Series as specified
in the related Prospectus Supplement, which may include (i) a fee payable from
the Certificate Account (a "REMIC Servicing Fee"), (ii) if Mortgage Loans are
included directly in the Pool, a specified servicing rate equal to the
difference between the Note Rate for each such Mortgage Loan and its
Pass-Through Rate, as well as late payment charges, assumption fees,
reinvestment income, if any, and other similar amounts set forth in the related
Pooling Agreement and/or (iii) in the case of the CitiMae Mortgage Loans and
Third Party Loans acquired on a 

                                       13
<PAGE>

servicing-retained basis, a master servicing fee ("Servicing Compensation"). To
the extent specified with respect to a Series in the related Prospectus
Supplement, Servicing Compensation may be divided between "normal servicing
compensation" and "additional servicing compensation." In the case of the
CitiMae Mortgage Loans and Third Party Loans acquired on a servicing-retained
basis, a fee may also be paid to third party subservicers or servicers (a
"Servicing Fee"). The Pooling Agreement generally provides that the servicer
shall not be subject to any liability to holders of Certificates other than by
reason of its willful misfeasance, bad faith or gross negligence in the
performance of its duties set forth in the Pooling Agreement. See "THE POOLING
AGREEMENTS."

                                    THE POOLS

  GENERAL

     Each Pool will consist of (i) Mortgage Loans and/or Mortgage Certificates
or other "regular interests" in another Pool to the extent specified in the
related Prospectus Supplement, (ii) the amount of any assets including cash, if
any, initially deposited in the Certificate Account, (iii) amounts deposited in
any Reserve Fund described in the Prospectus Supplement, (iv) distributions on
such Mortgage Certificates and/or Mortgage Loans (net of any servicing
compensation) (v) any real estate acquired through foreclosure or similar
proceeding and (vi) reinvestment earnings, if any, on such net distributions and
deposits. Any Pool including Mortgage Loans among its assets will also include
the interest of the Certificateholders in certain credit support and any
insurance policies with respect to such Mortgage Loans. Pools for Series having
monthly distributions are generally expected not to receive reinvestment
earnings on distributions that are held in the Certificate Account. The Mortgage
Certificates will be held by the Trustee or its nominee, and any Mortgage Loans
included in any Pool will be held for the Trustee by a custodian, solely for the
benefit of the related Series of Certificates.

     The following summaries of characteristics of the Mortgage Loans and the
CitiMortgageCertificates are subject to and qualified by reference to APPENDIX
A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES." 

MORTGAGE LOANS

     The Mortgage Loans included directly in a Pool or underlying
CitiMortgageCertificates in a Pool will be mortgage loans secured by first liens
on one- to four-family residential properties, and may be fixed rate or
adjustable rate loans, or participations or other beneficial interests in such
loans, which may provide for full amortization of principal, deferral of a
portion of interest, balloon payments of principal or have such other
characteristics as set forth in the related Prospectus Supplement. Properties
securing Mortgage Loans may include leasehold interests in residential
properties, the title to which is held by third party lessors. The Mortgage
Loans may also contain cooperative apartment loans evidenced by promissory notes
secured by security interests in shares issued by private, non-profit,
cooperative housing corporations and in the related proprietary leases or
occupancy agreements granting exclusive rights to occupy specified dwelling
units in such cooperatives' buildings. Each Mortgage Loan will be selected and
purchased by the Issuer for inclusion in the related Pool, or will be selected
by the Originator in connection with the issuance of a CitiMortgageCertificate,
from among those originated or acquired by an Originator in the ordinary course
of business activities of the Originator or acquired from an affiliate of an
Originator or from a Third Party Originator. Mortgage Loans in a Pool may be
covered by a guaranty or certain other credit support, as described in the
related Prospectus Supplement.

     The Mortgage Loans will have original individual principal balances of no
more than $2,500,000 and, except as otherwise set forth in the related
Prospectus Supplement, original maturities of from 10 to 30 years. Fixed rate
Mortgage Loans will be of a type specified in APPENDIX A.

     Adjustable rate Mortgage Loans will bear interest at a rate which will be
adjusted from time to time to equal (to the nearest eighth of a percent) a
certain number of basis points over an index interest rate, as specified in
APPENDIX A or the related Prospectus Supplement. Adjustments may be subject to
limits on the magnitude of any one adjustment and on the magnitude of aggregate
upward adjustments during the life of the Mortgage Loan. Adjustable rate
Mortgage Loans may provide for deferral of a certain portion of interest and
increases to the principal balances in order to limit the amount by which the
scheduled monthly payments will increase following an increase in the rate of
interest. The amount of the difference between the scheduled monthly payment and
the monthly interest accrued at the Mortgage Rate is added to the unpaid
principal balance of the Mortgage Loan and interest accrues on such added

                                       14
<PAGE>

principal at the then-applicable Mortgage Rate from the date of such addition.
Such an adjustment is referred to as "negative amortization". Negative
amortization tends to lengthen the weighted average life of the Mortgage Loans
and may cause payments near the maturity of the Mortgage Loan to be larger than
the previously scheduled monthly payments unless the terms of the Mortgage Loan
permit its maturity to be extended. The impact of any such negative amortization
on Certificateholders will be set forth in the Prospectus Supplement.

     If specified in the related Prospectus Supplement, adjustable rate Mortgage
Loans included in a Pool may convert at some future time to fixed rate mortgage
loans. The details of such conversion features and the effect on the Pool will
be described in the related Prospectus Supplement.

     At the Cut-Off Date for a Pool that includes adjustable rate Mortgage
Loans, the Pool may contain adjustable rate Mortgage Loans which are newly
originated and adjustable rate Mortgage Loans as to which one or more
adjustments have occurred. Adjustable rate Mortgage Loans that have not had
their first rate adjustment will generally bear interest at rates that are lower
than the rate that would otherwise be produced by the sum of the applicable
index and the number of basis points over such index used to compute the
applicable mortgage rate for such Mortgage Loan.

     If provided for in the applicable Prospectus Supplement, the Mortgage Loans
in a Pool or the Mortgage Loans underlying CitiMortgageCertificates included in
a Pool may be subject to temporary buydown plans ("Buydown Mortgage Loans")
pursuant to which the monthly payments made by the Mortgagor during the early
years of the Buydown Mortgage Loan will be less than the scheduled monthly
payments on the Buydown Mortgage Loan, the resulting difference to be made up
from buydown funds contributed by the Mortgagor, the Mortgagor's employer, the
seller or the builder of the related Mortgaged Property or another source (i) at
the time of origination of the Buydown Mortgage Loan or (ii) in some cases when
buydown funds are contributed by an employer, on an annual basis. Unless
otherwise specified in the applicable Prospectus Supplement and except for
Buydown Mortgage Loans funded in accordance with clause (ii) above, the buydown
funds will be placed on the Closing Date (as defined in the related Prospectus
Supplement) in an account established and maintained with a depository by the
Issuer or the Originator (or in the case of CitiMae Mortgage Loans, with the
related subservicer), and amounts will be withdrawn monthly from such account
promptly following receipt of the Mortgagor's monthly payment and deposited in
the related Certificate Account. See "DESCRIPTION OF CERTIFICATES--Distributions
to Certificateholders." Buydown funds with respect to any Series may be held in
the same deposit account as buydown funds for all buydown mortgage loans
serviced by the Issuer, the Originator or any subservicer. In the case of
buydown funds contributed on an annual basis by the Mortgagor's employer, such
buydown loans will generally have a buydown period of three years but may have a
buydown period of up to five years. The employer may or may not be required to
guarantee the payment of buydown funds even if the Mortgagor were no longer
employed by such employer.

     Unless otherwise specified in the related Prospectus Supplement, the
original principal amount of each Mortgage Loan will be not more than 90% of the
Original Value of the property securing such Mortgage Loan. Each Affiliated
Mortgage Loan having an original principal amount exceeding 90% of the Original
Value of the Mortgaged Property will be covered by primary mortgage insurance
against losses from default on such Mortgage Loan in an amount ranging from 12%
to 30% of the principal amount of the Mortgage Loan outstanding from time to
time. Such insurance will be in effect at least until the principal amount of
the Mortgage Loan is reduced to 80% of its Original Value. Each CitiMae Mortgage
Loan having an original balance exceeding 80% of the Original Value of the
Mortgaged Property will be covered by primary mortgage insurance against losses
from default on such mortgage loan in an amount ranging from 12% to 30% of the
principal amount of the Mortgage Loan outstanding from time to time. Third Party
Loans will be covered by primary mortgage insurance to the extent specified in
the related Prospectus Supplement. See "LOAN UNDERWRITING POLICIES--Loan
Underwriting Policies of the Affiliated Originators" and "--Loan Underwriting
Policies of the CitiMae Originators."

     The properties securing Mortgage Loans may consist of detached houses,
attached houses, row houses, individual units in planned unit developments,
individual condominiums or other types of one- to four-family residences or
interests in cooperatives (as defined in APPENDIX A). Although it is anticipated
that such properties will be predominantly primary residences, they may include
investment properties and vacation and second homes as well. Such properties may
be located in any of the fifty United States, the District of Columbia or the
Commonwealth of Puerto Rico.

     When the related Series of Certificates is issued the Issuer will assign
the Mortgage Loans without recourse to the Trustee for the benefit of the
Certificateholders. The Issuer will, however, be required to repurchase any
Mortgage 


                                       15
<PAGE>

Loans or Mortgage Certificates that do not conform in one or more material
respects to the representations and warranties in the Pooling Agreement
("Non-Conforming Loans") within 180 days after notice from the Trustee that they
are Non-Conforming Loans. The Issuer may substitute conforming Mortgage Loans or
Mortgage Certificates for Non-Conforming Loans on or before the day that is 180
days following the Startup Day of the REMIC with respect to such Series. If,
however, any Non-Conforming Loan would affect the status of the REMIC or subject
the REMIC to tax, the Issuer must repurchase such Non-Conforming Loan or
substitute a conforming Mortgage Loan therefor within the earlier of 90 days
after notice from the Trustee that the Mortgage Loan is a Non-Conforming Loan or
180 days following the Startup Day. See "--Substitution of Mortgage Loans"
below. The Startup Day generally will be the Closing Date (as defined in the
related Prospectus Supplement). As servicer, the Issuer is responsible for
administering and servicing the Mortgage Loans and Mortgage Certificates.

     In connection with assignment of the Mortgage Loans to the Trustee, the
Issuer will deliver to the Trustee (or a custodian acting on its behalf, which
may be an affiliate of the Issuer) the Mortgage Note, the Mortgage with evidence
of recording thereon, any other mortgage related documents, and assignments of
the Mortgage by the Originator to the Trustee. Such assignments will generally
be recorded after the Closing Date. See APPENDIX A: "THE MORTGAGE LOANS AND
CITIMORTGAGECERTIFICATES--Assignment of Mortgage Loans." 

MORTGAGE CERTIFICATES

  CitiMortgageCertificates

     This summary of CitiMortgageCertificates is subject to and qualified by
reference to APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES."

     Certificates evidencing fractional undivided interests in trusts will be
created by each of the Originators with respect to which an election may be made
to treat such trusts as REMICs under the Code. The property of such REMICs will
consist of pools of Mortgage Loans originated or acquired by one of the
Affiliated Originators or acquired by the Issuer. Such certificates will consist
of one or more classes of regular interests and one class of residual interests.
It is expected that the issuer of any CitiMortgageCertificate will be the
packager of the Mortgage Loans underlying such CitiMortgageCertificate and will
act as the servicer or master servicer (in such capacity, the "Servicer" or
"servicer") of such Mortgage Loans (or will subcontract with an affiliate to act
as subservicer). The Mortgage Loans may be covered by certain credit support
described in the Prospectus Supplement.

     The form of pooling and servicing agreement pursuant to which the
CitiMortgageCertificates will be issued will be substantially the same as the
Pooling Agreement with respect to a Pool in which the Mortgage Loans were
originated or acquired by an Affiliated Originator. The terms and provisions of
the relevant Pooling Agreement described in this Prospectus (including the
descriptions of distributions) would be applicable to any
CitiMortgageCertificate except that references to the Issuer will be deemed
references to the relevant Affiliated Originator and references to the Pool will
be deemed references to the Citibank Pool, the CMI Pool or the CFSB Pool, as the
case may be.

     The pool underlying a CitiMortgageCertificate will consist of the Mortgage
Loans, such funds as from time to time are deposited in the Certificate Account
for such CitiMortgageCertificate, property acquired by foreclosure or deed in
lieu of foreclosure of a Mortgage Loan or Transfer Instrument (as defined below)
as from time to time may be subject to the related Pooling Agreement, any credit
support and any insurance policies with respect to the Mortgage Loans. For
purposes of this Prospectus, a "Transfer Instrument" is a deed transferring an
interest in property subject to a Mortgage or any assignment or other instrument
of transfer transferring an interest in collateral (including shares of a
cooperative and the related occupancy agreement or proprietary lease) securing a
Mortgage Loan. Any default by any insurer under any such policy, any loss in
excess of policy limits or any uninsured loss may adversely affect distributions
on the CitiMortgageCertificates to the Trustee for the related Series of
Certificates, and may thus adversely affect distributions on such Certificates
to the Certificateholders. Each Pooling Agreement with respect to the same
Originator will contain substantially the same terms and conditions, except for
the Pass-Through Rate or Stated Rate (as defined therein), the date of issuance
of such series, the aggregate initial Adjusted Balance of Mortgage Loans
evidenced by such series, the minimum fractional undivided interest represented
by each CitiMortgageCertificate, the identity and address of the Trustee, the
amount of the credit support and other minor variations. Pursuant to each
Pooling Agreement, the Servicer will be responsible for servicing and
administering the related Mortgage Loans, but may at any time subcontract its
duties as servicer under any Pooling Agreement to any 

                                       16
<PAGE>

entity, including an entity more than 50% of the stock of which is owned,
directly or indirectly, by Citicorp. With respect to Mortgage Loans acquired by
the Trust from Citibank or CFSB, each of Citibank and CFSB intends to
subcontract its duties as servicer under each Pooling Agreement under which it
acts as servicer to CMI. CitiMortgageCertificates contained in a Pool may
represent all or some of the regular interests in a REMIC. It is expected that
CitiMortgageCertificates will be issued pursuant to participation or pooling and
servicing agreements entered into from time to time between the related seller
and the related certificate trustee or custodian. In addition, an affiliate of
such seller or of the Issuer may be a servicer for such pool of mortgage loans.
The mortgage loans underlying the CitiMortgageCertificates may be subserviced by
one or more loan servicing institutions under the supervision of the servicer.

     It is expected that all collections received by the servicers on the
mortgage loans (net of servicing fees to be retained by the servicers and such
other amounts as may be specified in the related pooling and servicing
agreement) will be deposited with the certificate trustee. Monthly distributions
of the principal and interest components of such collections (adjusted to the
stated rate or pass-through rate (as the case may be) borne by such
CitiMortgageCertificate) will be made to the Trustee for the
CitiMortgageCertificates of the related Series for deposit into the Certificate
Account for such Series.

     The Issuer will provide to any Certificateholder, without charge, on
written request, a copy (without exhibits) of the Pooling Agreement for any
series of CitiMortgageCertificates included in a Pool. Requests should be
addressed to: Citicorp Mortgage Securities, Inc., 909 Third Avenue, New York,
New York 10043.

     Distributions of principal and interest on each series of
CitiMortgageCertificates will be made by the Trustee or a paying agent on the
25th day (or if such 25th day is not a business day, no later than the business
day immediately following the 25th day) of each calendar month to the Trustee as
the person in whose name such CitiMortgageCertificates are registered at the
close of business on the last business day of the preceding month. The first
such distribution date for each series of CitiMortgageCertificates will be
specified in the applicable Prospectus Supplement. The Pool may also contain a
certificate evidencing an undivided interest in a trust comprised of Mortgage
Loans as to which trust an election has not been made to treat the trust
property as a REMIC. The terms and provisions of such certificate and any
Pooling Agreement pursuant to which any such certificate is issued will be set
forth in the related Prospectus Supplement.

  Issuer Certificates

     This summary of Issuer Certificates is subject to and qualified by
reference to APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES."

     The Pool with respect to any Series of Issuer Certificates may consist in
whole or in part of Issuer Certificates initially issued to the public by the
Issuer or an affiliate of the Issuer, and which represent all or a portion of
the regular interests in a pool of mortgage loans originated or acquired by one
or more of the Affiliated Originators or acquired by the Issuer ("Whole or
Partial Pool Issuer Certificates"). Whole or Partial Pool Issuer Certificates
included in a Pool may represent all or a portion of one or more classes or
subclasses of one or more series of previously issued Issuer Certificates.

     Each Whole or Partial Pool Issuer Certificate will have been issued
pursuant to a pooling and servicing agreement between the related issuer, which
is expected to be the Issuer, one or more Originators and/or affiliates of the
Issuer, and the trustee for such series of CitiCertificates (the "Underlying
Trustee"). Unless otherwise specified in the Prospectus Supplement, the terms of
such pooling agreement will generally conform to those provided in the Pooling
Agreement with respect to such Series of Certificates. See "THE POOLING
AGREEMENTS."

     Certain of the mortgage loans underlying a series of Whole or Partial Pool
Issuer Certificates may be covered by (i) individual policies of primary
mortgage insurance insuring against all or a portion of any foreclosure losses
on the particular mortgage loans covered thereby, (ii) subordination or guaranty
arrangements and/or (iii) such other policies of insurance and other forms of
credit support (including, without limitation, obligations to advance delinquent
payments) as may be specified in the related Prospectus Supplement. Unless
otherwise provided in the related Prospectus Supplement, no Whole or Partial
Pool Issuer Certificate will be so insured or guaranteed.

     Unless otherwise provided in the related Prospectus Supplement, it is
expected that all collections received by servicers with respect to the mortgage
loans underlying each series of Whole or Partial Pool Issuer Certificates (net
of servicing fees to be retained by such servicers and such other amounts as may
be specified in the related pooling and

                                       17
<PAGE>

servicing agreement), including monthly distributions of the principal and
interest components of such collections (adjusted to the stated rate or
pass-through rate (as the case may be) borne by such Whole or Partial Pool
Issuer Certificate) will be distributed directly to the related Underlying
Trustee.

     The Prospectus Supplement will specify, to the extent relevant and to the
extent such information is reasonably available to the Issuer and the Issuer
reasonably believes such information to be reliable, (i) the aggregate
approximate principal amount and type of each class or subclass of Whole or
Partial Pool Issuer Certificates to be included in the Pool; (ii) certain
characteristics of the mortgage loans which comprise the underlying assets for
each Whole or Partial Pool Issuer Certificate, on a pool by pool basis,
including (a) the aggregate Adjusted Balance of such mortgage loans and the
years of origination thereof, (b) if Converted Mortgage Loans with an aggregate
Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of all mortgage
loans in any pool underlying a Whole or Partial Pool Issuer Certificate were
delivered, the aggregate Adjusted Balance of any such Converted Mortgage Loans,
(c) the original loan-to-value ratios of the mortgage loans of each such pool,
(d) the types of Mortgaged Properties securing the mortgage loans, (e) the
geographic distribution of the Mortgaged Properties, prepared on a
state-by-state basis for states where mortgage loans having an aggregate
Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of mortgage
loans in the related Pool are located, (f) if Buydown Mortgage Loans with an
aggregate Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of
all mortgage loans in the related Pool were delivered, the aggregate Adjusted
Balance of Buydown Mortgage Loans in the related Pool, (g) if loans on
residential leasehold properties ("Leasehold Loans") with an aggregate Adjusted
Balance exceeding 10% of the aggregate Adjusted Balance of all mortgage loans in
the related Pool were delivered, the aggregate Adjusted Balance of Leasehold
Loans in the related Pool and (h) if 15-year, fixed rate tiered-payment mortgage
loans originated by CFSB's California branches and providing for a prepayment
penalty during the first 12 months following origination with an aggregate
Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of all mortgage
loans in the related Pool were delivered, the aggregate Adjusted Balance of such
mortgage loans in the related Pool; (iii) the maximum original term-to-stated
maturity of each series of Whole or Partial Pool CitiCertificates; (iv) the
weighted average term-to-stated maturity of each series of Whole or Partial Pool
Issuer Certificates; (v) the pass-through rate for each class or subclass of
Whole or Partial Pool Issuer Certificates; (vi) the weighted average
pass-through rate of each Whole or Partial Pool Issuer Certificate; (vii) the
servicer of the mortgage loans underlying each Whole or Partial Pool Issuer
Certificate and the Underlying Trustee with respect to each Whole or Partial
Pool Issuer Certificate; (viii) certain characteristics or credit enhancement,
if any, such as reserve funds, insurance policies, letters of credit or
guarantees, relating to the mortgage loans underlying each Whole or Partial Pool
Issuer Certificate; (ix) the terms on which underlying mortgage loans for each
Whole or Partial Pool Issuer Certificate may, or are required to, be repurchased
prior to stated maturity; and (x) the terms on which substitute mortgage loans
may be delivered to replace those initially deposited with each Underlying
Trustee.

     More specific information concerning each Whole or Partial Pool Issuer
Certificate, the mortgage loans underlying each such Issuer Certificate, and
related servicing, insurance, subordination and/or other credit support
arrangements, if any, will be set forth in the related Prospectus Supplement.

  Agency Certificates

     This summary of Agency Certificates is subject to and qualified by
reference to APPENDIX B: "THE AGENCY CERTIFICATES."

     The Issuer may acquire for any Pool "fully-modified pass-through"
mortgage-backed certificates ("GNMA Certificates") issued by private issuers and
guaranteed by the Government National Mortgage Association ("GNMA"), Mortgage
Participation Certificates ("FHLMC Certificates") guaranteed by the Federal Home
Loan Mortgage Corporation ("FHLMC") and Mortgage Pass-Through Certificates
("FNMA Certificates") guaranteed by Fannie Mae ("FNMA").

     GNMA is a wholly-owned corporate instrumentality within the United States
Department of Housing and Urban Development. GNMA is authorized to guarantee the
timely payment of the principal of and interest on GNMA Certificates, which
guarantee is backed by the full faith and credit of the United States. Any
issuer which is unable to make payments on such GNMA Certificates as they become
due is required to promptly notify GNMA and request payment by GNMA, whereupon
GNMA will make such payment directly to the holders of such GNMA Certificates.

     FNMA is a federally chartered and privately owned corporation organized
under the Federal National Mortgage Association Charter Act. FNMA purchases home
mortgage loans with funds acquired in part from the sale of its 

                                       18
<PAGE>

Guaranteed Mortgage Pass-Through Certificates. FNMA guarantees that it will
distribute to holders of FNMA Certificates their proportionate interests in
passed-through payments of principal of and interest on the underlying loans
(including principal prepayments).

     FHLMC is a corporate instrumentality of the United States created pursuant
to Title III of the Emergency Home Finance Act of 1970, as amended. FHLMC
purchases mortgage loans and participation interests in mortgage loans that meet
certain statutory standards, and resells them in the form of FHLMC Certificates.
FHLMC guarantees that it will distribute to holders of FHLMC Certificates their
proportionate interests in passed-through payments of principal of and interest
on the underlying loans.

     The guaranties of FNMA and FHLMC are backed only by the credit of FNMA and
FHLMC, respectively. The full faith and credit of the United States is not
pledged to payments that may be required under such guaranties. Neither the
United States nor any agency thereof is required to finance FNMA's or FHLMC's
operations or to assist FNMA or FHLMC in any manner.

CERTIFICATE ACCOUNT

     The Trustee will, as to each Series of Certificates, establish and maintain
a separate account or accounts, including any such account maintained by a
paying agent (collectively, the "Certificate Account"), for the benefit of the
Certificateholders. The Certificate Account may bear interest. Except with
respect to the CitiMae Mortgage Loans and the Third Party Loans acquired on a
servicing-retained basis, all payments (net of servicing fees) on the Mortgage
Loans or Mortgage Certificates will be deposited directly into the Certificate
Account as soon as practicable after receipt thereof but in any case within two
business days of receipt and posting. The Pooling Agreement for each Series may
authorize the Trustee to invest at the Issuer's discretion distributions
received on the assets in a Pool (including Voluntary Advances and payments
under the credit support) in certain investments ("Eligible Investments") that
will qualify as "permitted investments" under Code Section 860G(a)(5). Eligible
Investments may be made by the Trustee upon instructions from the Issuer and, if
made, will generally mature not later than the day preceding the next
Distribution Date for such Series (or on such Distribution Date in the case of
Eligible Investments which are the obligations of the Trustee). Eligible
Investments include, among other investments, obligations of the United States
or of any agency thereof, certificates of deposit, federal funds, time deposits
and bankers' acceptances sold by eligible commercial banks (including affiliates
of the Issuer such as Citibank), any other demand or time deposit or certificate
of deposit fully insured by the Federal Deposit Insurance Corporation (the
"FDIC") either through the Bank Insurance Fund (the "BIF") or the Savings
Association Insurance Fund (the "SAIF"), commercial paper carrying the ratings
specified in the related Pooling Agreement of each Rating Agency rating the
Certificates of such Series that has rated such commercial paper, certain
repurchase agreements of United States government securities with eligible
commercial banks and certain guaranteed investment contracts.

     Unless otherwise set forth in the related Prospectus Supplement, all
payments on Mortgage Loans and Mortgage Certificates, together with any
reinvestment income thereon and any amounts withdrawn from any Reserve Fund for
such Series and deposited into the Certificate Account for such Series, will be
available to make distributions on the Certificates of such Series on the next
succeeding Distribution Date or Special Distribution Date for such Series. Any
funds remaining in the Certificate Account immediately following a Distribution
Date (other than amounts representing early payments of installments of
principal and interest on Mortgage Loans directly held in the Pool which are due
on future Due Dates or Principal Prepayments) will be promptly distributed to
the holders of the Residual Certificates.

     In the case of Mortgage Loans participating in a "prepayment program" (as
described in APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGE
CERTIFICATES--Payments on Mortgage Loans in Pools"), payments on such Mortgage
Loans received under such a program will not be remitted to the Certificate
Account until released for payment under the terms of such program.

MINIMUM PREPAYMENT AGREEMENT

     The Issuer may enter into an agreement (a "Minimum Prepayment Agreement")
with an institution meeting the criteria of the Rating Agency rating the related
Series to enable the Trustee to make distributions of principal on the
Certificates of such Series in accordance with a schedule set forth in the
related Prospectus Supplement. Funds would be provided under the Minimum
Prepayment Agreement in the event that aggregate scheduled principal payments

                                       19
<PAGE>

and prepayments on the Mortgage Loans and/or Mortgage Certificates included in
the related Pool were not sufficient to make distributions in reduction of the
Stated Amount of such Certificates in accordance with such Minimum Prepayment
Schedule. Such Minimum Prepayment Agreement may obligate the institution to
purchase, from time to time, Mortgage Loans and/or Mortgage Certificates
included in the Pool pursuant to a selection process set forth in such agreement
for an amount specified in the related Prospectus Supplement.

     The related Prospectus Supplement will describe the terms and conditions of
any Minimum Prepayment Agreement if a Minimum Prepayment Agreement is to be a
part of the Pool.

MINIMUM REINVESTMENT AGREEMENT

     The Issuer may enter into an agreement (a "Minimum Reinvestment Agreement")
with an institution meeting the criteria of the Rating Agency rating the related
Series. Amounts required to be deposited in any account or fund for a related
Series will be invested pursuant to such agreement. If a Minimum Reinvestment
Agreement is entered into with respect to a Series of Certificates, reinvestment
earnings on funds in the Certificate Account will not belong to the Servicer as
additional servicing compensation but will be available to make distributions on
the Certificates in accordance with their terms. The applicable interest rates
for funds invested under such agreement will be described in the related
Prospectus Supplement if a Minimum Reinvestment Agreement is to be a part of the
Pool.

COLLECTION OF PAYMENTS

     The Mortgage Certificates included in a Pool for a Series of Certificates
will be registered in the name of the Trustee or its nominee or, in the case of
Mortgage Certificates issued only in book-entry form, with a member of the
Federal Reserve System, so that in each case all distributions thereon will be
made directly to such Trustee. The Mortgage Loans included in a Pool will be
assigned to the Trustee and the related Mortgage Notes, endorsed to the Trustee
or in blank, will be delivered to the Trustee or its custodian. The obligation
of such Trustee to make distributions on the Certificates is limited to the
amount of payments (net of servicing compensation) on the Mortgage Certificates
and Mortgage Loans that were actually received by it unless the Issuer enters
into a Minimum Prepayment Agreement. The Trustee may not assign, transfer,
pledge or dispose of any assets in the Certificate Account for such Series,
except to a successor Trustee with respect to such Series, the holders of the
Residual Certificates or the holders of CitiCertificates for such Series as set
forth in the Pooling Agreement and except as permitted under the Pooling
Agreement in connection with foreclosures and other realizations on defaulted
Mortgage Loans. See "--Substitution of Mortgage Loans" below.

SUBSTITUTION OF MORTGAGE LOANS

     Subject to the limitations set forth in the Pooling Agreement, the Issuer
may, on any day prior to 180 days after the settlement date of the related
Series of Certificates (the "Startup Day") (or, if such day is not a Business
Day, on the next previous Business Day) (or 90 days after discovery, if earlier,
if the defect affects the status of the Mortgage Loan as a "qualified mortgage"
for REMIC purposes), but solely in lieu of any obligation it may have to
repurchase a Non-Conforming Loan, deliver to the Trustee other Mortgage Loans in
substitution for any one or more Mortgage Loans included in the Pool. Any such
substitute Mortgage Loan will be fully paid up on the substitution day and will
have a principal balance on the substitution day that is at least equal to the
principal balance on the substitution day of the Non-Conforming Loans for which
it is substituted, an interest rate equal to or greater than that of such
Non-Conforming Loans, an original term to maturity equal to that of such
Non-Conforming Loans and a maturity date not earlier than one year prior to, and
in no event later than, that of such Non-Conforming Loans. Substitutions of
Mortgage Loans and/or Mortgage Certificates will be permitted in the event of
breaches of representation and warranties with respect to any original Mortgage
Loan and/or Mortgage Certificate or in the event the documentation with respect
to any Mortgage Loan is determined by the Trustee to be incomplete. The period
during which such substitution will be permitted generally will not exceed two
years for pools from the date the related Series is issued.

     The related Prospectus Supplement will describe any other conditions upon
which Mortgage Loans and/or Mortgage Certificates may be substituted for
Mortgage Loans and/or Mortgage Certificates initially included in the Pool.

activities through its New York Banking Unit (the "NYBU"). Except in connection
with mortgage pass-through certificates issued by it from time to time, Citibank
has not engaged in any significant servicing activities on behalf of
unaffiliated persons with respect to conventional residential mortgage or
cooperative loans.

     The NYBU is responsible for Citibank's consumer banking business within
that portion of the New York Metropolitan Area which includes the nine counties
(Westchester, Nassau, Suffolk, Kings, Richmond, New York, Bronx, Rockland and
Queens) within and surrounding New York City. Citibank offers a wide range of
consumer banking products and services, including mortgage and cooperative
apartment loans.

     The principal executive offices of Citibank are located at 399 Park Avenue,
New York, New York 10043. Its telephone number is (212) 559-1000.

CITIMAE, INC.

     CitiMae, Inc. ("CitiMae"), a Delaware corporation and a wholly owned
subsidiary of Citibank, is primarily engaged in the purchase and sale of
mortgage loans, the performance of master servicing functions and the
securitizing of mortgage loans. Its principal executive offices are located at
399 Park Avenue, New York, New York 10043. Its telephone number is (212)
793-5880.

     At March 31, 1996, CitiMae master serviced mortgage loans, on behalf of
Citibank, with principal balances of approximately $4,843,000,000. CitiMae
enters into agreements with various approved servicers to perform, as
independent contractors, certain servicing functions for Citibank, as master
servicer. See "LOAN UNDERWRITING POLICIES--Loan Underwriting Policies of the
CitiMae Originators."

     Set forth below is a description of aspects of CitiMae's purchase program
for Mortgage Loans eligible for inclusion in a Pool.

     The Issuer will purchase Mortgage Loans either directly or indirectly from
CitiMae or its affiliates or from approved sellers which may be affiliates of
the Issuer or CitiMae. CitiMae or its affiliates has approved (or will approve)
individual institutions as eligible sellers by applying certain criteria,
including the seller's depth of mortgage origination experience, servicing
experience and financial stability. From time to time, however, CitiMae or its
affiliates may purchase Mortgage Loans from sellers which, while not meeting the
generally applicable criteria, have been reviewed by it and found to be
acceptable as sellers of Mortgage Loans.

     Underwriting standards are intended to evaluate the Mortgagor's credit
standing and repayment ability and the value and adequacy of the Mortgaged
Property as collateral. Underwriting standards are applied in a standard
procedure which complies with applicable federal and state laws and regulations.

     In determining the adequacy of the property as collateral, an appraisal is
generally made of each property considered for financing. The appraiser is
required to inspect the property and verify that it is in good condition and
that construction, if new, has been completed. The appraisal is based on the
appraiser's judgment of values, giving appropriate weight to both the market
value of comparable homes and the cost of replacing the property.

     See also "LOAN UNDERWRITING POLICIES--Loan Underwriting Policies of the
CitiMae Originators". 

     If CitiMae Mortgage Loans are included in a Pool, the Issuer intends to
enter into a Subservicing Agreement with CitiMae (the "Subservicer") pursuant to
which the Subservicer will agree to perform certain functions for the Servicer
relating to the purchase of the Mortgage Loans and the servicing and
administering of the CitiMae Mortgage Loans. Under the Subservicing Agreement,
the Subservicer will agree, among other things, to perform the Servicer's
obligations with respect to the servicing of the CitiMae Mortgage Loans and the
Servicer's servicing obligations under the Pooling Agreement which will include
making advances to Certificateholders under circumstances in which the Servicer
would be obligated to make such advances, and repurchasing Mortgage Loans from
the Trustee where the Servicer would be obligated to so repurchase. Any actions
of the Subservicer taken pursuant to the Subservicing Agreement will be for the
Servicer with the same force and effect as though performed directly by the
Servicer and the Servicer will at all times remain responsible for the
performance of its duties under the Pooling Agreement. The Subservicer will be
paid a fee by the Servicer for its services.

THIRD PARTY ORIGINATORS

     If Third Party Loans having an aggregate Adjusted Balance exceeding 10% of
the aggregate Adjusted Balance of the Mortgage Loans in a Pool are included in a
Pool, the related Prospectus Supplement will identify the Third Party
Originators of such Third Party Loans.

                                       22
<PAGE>

     Unless otherwise specified in the related Prospectus Supplement, each Third
Party Originator will be required to satisfy the qualifications set forth in
this paragraph. Each Third Party Originator must be an institution experienced
in originating mortgage loans of the type contained in the related Pool in
accordance with accepted practices and prudent guidelines. Each Third Party
Originator must be a savings and loan association, savings bank, commercial
bank, credit union, insurance company or a mortgagee approved by the Secretary
of Housing and Urban Development.

                           LOAN UNDERWRITING POLICIES

LOAN UNDERWRITING POLICIES OF THE AFFILIATED ORIGINATORS

     Except as specifically noted below and except as may be specified in the
applicable Prospectus Supplement, residential real estate mortgage loans
originated or acquired from affiliated or unaffiliated third parties by the
Affiliated Originators are subject to the same underwriting process. For certain
residential mortgage loans the Affiliated Originators have contracted with or
delegated the underwriting process to certain unaffiliated third parties. The
underwriting process, which is described below, assesses the prospective
borrower's ability to repay and the adequacy of the property as collateral for
the loan requested. The loan underwriting policies of each Affiliated Originator
require such Originator's loan underwriters to be satisfied that the value of
the property being financed currently supports, and will likely support in the
future, the outstanding loan balance with sufficient excess value to protect
against minor adverse shifts in real estate values. In general, it is the policy
of each Affiliated Originator not to make conventional one- to four-family real
estate loans with more than 95% loan-to-value ratios. Unless otherwise specified
in the related Prospectus Supplement, a Pool will not contain any Real Estate
Loans with more than a 95% loan-to-value ratio.

     Each Affiliated Originator's real estate lending process for one- to
four-family residential mortgage loans follows a standard procedure, established
to comply with applicable federal and state laws and regulations. Initially, a
prospective borrower is required to fill out an application designed to provide
pertinent information about the prospective borrower, the property to be
financed and the type of loan desired. As part of the description of the
prospective borrower's financial condition, each Affiliated Originator requires
a current balance sheet describing assets and liabilities and a statement of
income and expenses, proof of income such as a paycheck stub or W-2 form (except
for certain self-employed prospective borrowers), proof of liquid assets
(required as of April 1991), telephone verification of employment (required as
of April 1991), which may be verified utilizing a third party national
employment verification service, and a credit report which summarizes the
prospective borrower's credit history with local merchants and lenders and any
record of bankruptcy. From February 1991 until May 1997, it was the policy of
each Affiliated Originator to obtain at least two credit reports (which could be
in the form of a merged credit bureau report) with respect to a prospective
borrower. Since May 1997, it has been the policy of each Affiliated Originator
to obtain the single most comprehensive readily available credit bureau report
with respect to a prospective borrower. Prior to May 1997, self-employed
prospective borrowers were required to submit their federal income tax returns
for the most recent two years and a separate statement of income and expenses.
Since May 1997, self-employed prospective borrowers are required to submit a
copy of their most recently filed Form 1040, without schedules. In the case of
mortgage loans originated or acquired after July 1993 by the Affiliated
Originators, facsimile copies of certain verification documents (such as bank
statements and verification of employment) may be accepted in lieu of originals.

     If the proposed mortgage loan does not exceed 65% (prior to December 1992,
such percentage could be up to 80%) of the value of the underlying property
based on the lesser of the appraised value determined in an appraisal obtained
by the Affiliated Originator at the origination of such mortgage loan or the
sale price for such property (the "Original Value"), certain self-employed
prospective borrowers may be exempt from some or all of the requirements that
they provide financial statements, current federal income tax returns and proof
of income. However, each Affiliated Originator during 1990 and 1991 implemented
as part of its underwriting policy that telephone verification of employment is
required and, beginning in April 1991, proof of liquid assets, as described
below. Certain high net worth prospective borrowers with ongoing banking
relationships with Citicorp's Private Banking Group may be exempt from the
employment verification process.

     Once the employment verification and the credit report are received, a
determination is made as to whether the prospective borrower has sufficient
monthly income available to meet the borrower's monthly obligations on the
proposed loan and other expenses related to the residence as well as to meet
other financial obligations and monthly 

                                       23
<PAGE>

living expenses. Each Affiliated Originator has established as lending
guidelines that the mortgage payments, plus applicable real property taxes and
any condominium or homeowner association common charges and hazard insurance,
should not exceed 33% (34% in the case of ARMs) of the borrower's gross income,
or that all monthly payments, including those mentioned above and other fixed
obligations, such as car payments, should not exceed 38% of gross income. Since
May 1997, loans that meet the Affiliated Originator's minimum credit score and
delinquency requirements may have debt burden ratios of up to 45% and, for
certain corporate relocation loans, 50%. Where there are two individuals
co-signing the mortgage note or documents, the income and debt of both are
included in the computation. Since May 1997, each Affiliated Originator does not
require income or asset verification in the case of their current mortgagors
seeking to refinance their mortgage loans, if such refinancing meets such
Affiliated Originator's minimum seasoning, payment history and credit score
requirements. In the case of other mortgagors seeking to refinance their
mortgage loans, each Affiliated Originator does not require asset verification
and allows a debt burden ratio of up to 45% for loans that meet such Affiliated
Originator's minimum seasoning, payment history and credit score requirements.
In the case of ARMs, the initial mortgage rate may be lower than the sum of the
then-applicable Index and Mortgage Margin for such loan, and the determination
of whether the prospective borrower has sufficient monthly income is made based
upon such lower initial mortgage rate. In the case of mortgage loans originated
by the California branches of CFSB prior to June 1991, the actual mortgage
payments may be higher due to a higher mortgage rate at the time the loan
documents are prepared, but such mortgage rate generally will not exceed the
anticipated rate used in such analysis by more than one percent. Often, however,
other credit considerations may cause a loan underwriter to depart from these
guidelines, and a loan underwriter may require additional information or further
verification of information provided so as to compensate for the exception to
the Affiliated Originator's lending guidelines.

     Since April 1991, each Affiliated Originator's underwriting policies have
required it to make a determination as to whether the prospective borrower has
sufficient liquid assets to acquire the property to be financed, taking into
account, among other things, proceeds from the sale of any prior residence and
cash on deposit in banks. This determination may be made from such evidence as
the existence of a contract for sale of any prior residence and bank statements
supplied by the prospective borrower. As described in the preceding paragraph,
asset verification may be waived for certain refinancings.

     Each Affiliated Originator requires an appraisal to be made of each
property to be financed, which may be a master appraisal in the case of bulk
commitments. The appraisal is conducted by either an independent fee appraiser,
a specially trained employee of the Affiliated Originator or an employee of an
affiliate. The person conducting the appraisal personally visits the property
and estimates its market value on the basis of comparable properties. Since
April 1997, each Affiliated Originator accepts, in lieu of originals, electronic
appraisals without photographs from appraisers who utilize certain approved
appraisal software packages. Neither the independent appraisers nor employees
receive any compensation dependent upon either the amount of the loan or its
consummation. In normal practice, the Affiliated Originator's judgment of the
appraisal determines the maximum amount which will be lent on the property. In
connection with the refinancing of an existing mortgage originated or acquired
by certain Affiliated Originators, such Originators may not cause a current
appraisal of the underlying property to be prepared unless the then outstanding
principal amount of the mortgage loan is increased by an amount in excess of the
mortgagor's out-of-pocket costs associated with the refinanced transaction plus
(at the option of qualifying borrowers) the amount required to pay off any
junior liens on the property. In connection with the modification of an existing
mortgage pursuant to a Modification Agreement, a current appraisal of the
underlying property may not be prepared.

     Each Affiliated Originator obtains or causes to be obtained a search of the
liens of record to which the property being financed is subject at the time of
origination. Title insurance or, in lieu thereof, an attorney's opinion of title
in those jurisdictions in which such practice is acceptable, is required in the
case of all mortgage loans, except that with respect to Cooperative Loans, an
Affiliated Originator does not require a borrower or the cooperative to obtain
title insurance of any type or to obtain a title search of the property on which
the cooperative apartment building is located.

     Since January 1995, each Affiliated Originator has used a credit scoring
system as part of its underwriting process. This credit scoring system assesses
the prospective borrower's ability to repay a mortgage loan based upon certain
predetermined mortgage loan characteristics and credit risk factors. All
prospective borrowers remain subject to verification of employment, income,
assets and credit history, unless provided otherwise herein. All credit scored
loans are rated strong, satisfactory or inconclusive. Mortgage loans rated
"strong" or "satisfactory" are not subjected to the normal loan underwriting
process described herein, but are subject to verification of property value. 
Mortgage
                                       24
<PAGE>

loans rated "inconclusive" are underwritten in accordance with the normal loan
underwriting policies described herein.

     An Affiliated Originator may originate Leasehold Loans. Leasehold Loans are
approved in accordance with such Affiliated Originator's standard underwriting
criteria. An ALTA leasehold title insurance policy is required, which contains
no exceptions for any adjustable features of the lease. The title insurance
policy must assure that the Affiliated Originator's first mortgage is not
subordinate to any lien or encumbrance other than the land lease. Additionally,
when deemed necessary, the California branches of CFSB require that a consent to
assignment of lease and/or subordination agreement be obtained and recorded.
Furthermore, each Affiliated Originator requires that the leasehold estate be
assignable or transferable if it is subjected to the mortgage lien.

     The land lease should guarantee such Affiliated Originator's right to
receive any notice of default by the borrower and the right to cure the default.
Payments due pursuant to the land lease are taken into account in both debt
ratio calculations in connection with the underwriting of such mortgage loans.
Finally, each Affiliated Originator requires that the term of the lease must
extend at least ten years longer than the scheduled maturity on the mortgage
loan.

     Prior to 1986, the Affiliated Originators did not generally make one- to
four-family real estate loans with loan-to-value ratios above 80% unless such
Affiliated Originator had obtained primary mortgage insurance coverage. From
1986 through January 1993, each Affiliated Originator originated mortgage loans
with loan-to-value ratios in excess of 80% but not more than 90% without
obtaining primary mortgage insurance. Since February 1993, it has been the
policy of each Affiliated Originator not to make one- to four-family real estate
loans with loan-to-value ratios above 80% without obtaining primary mortgage
insurance. Certain corporate relocation programs, offered by the Affiliated
Originators to employees of certain approved corporations, permit single family
real estate loans with loan-to-value ratios in excess of 80% without requiring
primary mortgage insurance. For these loans, however, the applicable corporate
employer generally guarantees the excess of the amount of the mortgage loan over
the 80% loan-to-value amount. Certain other corporate relocation programs permit
the providing of subordinate financing by the corporate employer at the time of
the origination of the first priority mortgage loan by an Affiliated Originator.

     The Affiliated Originators offer certain programs under which they may make
real estate loans with a loan-to-value ratio of up to 80% and subordinate
financing similar to those described in the preceding paragraph to borrowers not
participating in a corporate relocation program without requiring any primary
mortgage insurance or third party guarantees.

     Each Affiliated Originator's underwriting standards are designed to
evaluate a borrower's credit standing and repayment ability and the value and
adequacy of the mortgaged property as collateral. In the case of a Converted
Mortgage Loan, the borrower's repayment ability will have been determined only
at origination on the basis of such borrower's then-current income and
obligations and interest rates for adjustable interest rate mortgage loans
which, traditionally, have been lower than the interest rates charged by
mortgage lenders on fixed interest rate mortgage loans. The borrowers at their
exclusive options may elect to convert their mortgage loans into fixed interest
rate loans or to continue with the adjustable interest rate features. A
borrower's conversion option is conditional only upon a review by the applicable
Affiliated Originator of the loan payment history and payment of a conversion
fee. It is possible that the fixed interest rate payable by the borrower upon
conversion will be higher than the adjustable interest rate otherwise payable.
In that event, the borrower's capacity to repay the loan may be reduced.

     Unless otherwise specified in the Prospectus Supplement, no ARM Pool will
contain ARMs which provide for conversion options.

     Each Affiliated Originator originates Buydown Mortgage Loans. Unless
otherwise specified in the applicable Prospectus Supplement, (i) during the
buydown period, each of the Buydown Mortgage Loans will provide for payments
payable by the Mortgagor based on a hypothetical reduced interest rate (the
"buydown mortgage rate") that will not have been more than 5% below the mortgage
rate at origination, (ii) the annual increase in the buydown mortgage rate
during the buydown period will not exceed 1% or in the case of tiered payment
Mortgage Loans the annual increase in the mortgagors' monthly payment will
increase as described in the "THE POOLS--Mortgage Loans" and (iii) the buydown
period will not exceed three years in the case of Citibank Pools and Buydown
Mortgage Loans originated by the Florida branches of CFSB, five years in the
case of CMI Pools, and six years in the case of CFSB Pools (other than those
Buydown Mortgage Loans originated by its Florida branches). For all Pools, with
respect to Mortgage Loans originated prior to October 1, 1991, the maximum
amount of the buydown funds that may be contributed by the seller or builder of
the related Mortgaged Property is limited to 9% of the Original Value of the
Mortgaged Property; with respect to Mortgage Loans originated on or after
October 1, 1991, the maximum amount of buydown funds that may 

                                       25
<PAGE>

be contributed by the seller or builder of the related Mortgaged Property is
limited to 6% of the Original Value of the Mortgaged Property. These limitations
do not apply to contributions from the Mortgagor or immediate relatives or the
employer of the mortgagor. Except as may be otherwise indicated in the
applicable Prospectus Supplement, the Mortgagor under each Buydown Mortgage Loan
will have been qualified at an interest rate which is not more than 5% per annum
below the current mortgage rate at origination. Accordingly, the repayment of a
Buydown Mortgage Loan is dependent on the ability of the Mortgagor to make
larger monthly payments after the buydown funds have been depleted and, for
certain Buydown Mortgage Loans, while such funds are being depleted.

     All the above described Affiliated Originators (other than Citibank)
purchase mortgage loans originated by other parties. Except as may be otherwise
specified in the applicable Prospectus Supplement, mortgage loans acquired from
other parties, other than in a bulk purchase, are reviewed by such Affiliated
Originators or by unaffiliated third parties under contracts with such
Affiliated Originators for compliance with the above described underwriting
criteria, and such Affiliated Originators have the right to reject loans which
fail to conform to such criteria. In connection with an acquisition of mortgage
loans in a bulk purchase, (i.e., loans aggregating more than $15,000,000) from a
nationally recognized mortgage loan originator, the acquiring Affiliated
Originator will review the selling originator's underwriting policies and
procedures with a view to their compliance with such Affiliated Originator's or
FNMA/FHLMC underwriting standards and, in addition, will conduct a limited
mortgage loan file review.

LOAN UNDERWRITING POLICIES OF THE CITIMAE ORIGINATORS

     Except as described below, each Mortgage Loan contributed to the Trust by a
CitiMae Originator has satisfied the credit, appraisal and underwriting
guidelines established by CitiMae or one of its affiliates, as set forth in its
Sellers' Guide, which forms a part of the agreement pursuant to which
unaffiliated loan originators sell mortgage loans to CitiMae or one of its
affiliates. Such underwriting guidelines may be varied in cases deemed
appropriate by CitiMae or one of its affiliates. To determine satisfaction of
such underwriting guidelines, CitiMae or a loan reviewer reviewed the Mortgage
Loans.

     CitiMae's underwriting guidelines are intended to evaluate the Mortgagor's
credit standing and repayment ability and the value and adequacy of the
Mortgaged Property as collateral. CitiMae's underwriting guidelines are applied
in a standard procedure which complies with applicable federal and state laws
and regulations. Initially, a prospective Mortgagor is required to fill out a
detailed application designed to provide pertinent credit information. As part
of the description of the Mortgagor's financial condition, the Mortgagor is
required to provide a current balance sheet describing assets and liabilities
and a statement of income and expenses, as well as an authorization to apply for
a credit report which summarizes the Mortgagor's credit history with local
merchants and lenders and any record of bankruptcy. In addition, an employment
verification is obtained from the Mortgagor's employer wherein the employer
reports the length of employment with that organization, the current salary, and
an indication as to whether it is expected that the Mortgagor will continue such
employment in the future. If a prospective Mortgagor is self-employed, the
Mortgagor is required to submit copies of signed tax returns. The Mortgagor also
authorizes deposit verification at all financial institutions where the
Mortgagor has demand or savings accounts.

     Once the employment and deposit verifications and the credit report are
received, a determination is made as to whether the prospective Mortgagor has
sufficient monthly income available (i) to meet the Mortgagor's monthly
obligations on the proposed mortgage loan and other expenses related to the
Mortgaged Property (such as property taxes, hazard insurance and maintenance and
utility costs) and (ii) to meet other financial obligations and monthly living
expenses.

     In determining the adequacy of the property as collateral, an independent
appraisal is made of each property considered for financing. The appraiser is
required to inspect the property and verify that it is in good condition and
that construction, if new, has been completed. The appraisal is based on the
appraiser's judgment of values, giving appropriate weight to both the market
value of comparable homes and the cost of replacing the property.

     CitiMae and its affiliates employ alternative underwriting guidelines for
certain qualifying mortgage loans underwritten by CitiMae and its affiliates.
Depending on the facts and circumstances of a particular case, CitiMae may
accept mortgage loans based upon limited documentation that eliminates the need
for either income verification 

                                       26
<PAGE>

and/or asset verification. The objective of the limited documentation guidelines
is to shift the emphasis of the underwriting process from the credit standing of
the Mortgagor to the value and adequacy of the Mortgaged Property as collateral.
A borrower(s) ability and willingness to repay a mortgage loan in a timely
manner must be demonstrated by the quality, quantity and durability of income
history, history of debt management and net worth accumulation. If greater than
10% of the Mortgage Loans by aggregate Adjusted Balance as of the Cut-Off Date
were originated under limited documentation guidelines, the percentage of
Mortgage Loans originated under such guidelines will be as provided in the
Prospectus Supplement.

     Depending upon the facts and circumstances of a particular case, CitiMae or
one of its affiliates may accept mortgage loans based upon seasoning and payment
histories without obtaining standard underwriting documentation. The objective
of the seasoned underwriting guidelines is to shift the emphasis of the
underwriting process from the credit standing and repayment ability of the
Mortgagor at the time of origination to the actual repayment performance of the
related mortgage loan. If greater than 10% of the Mortgage Loans (by Adjusted
Balance as of the Cut-Off Date) were originated under seasoned mortgage loan
guidelines, the percentage of such Mortgage Loans by Adjusted Balance will be
provided in the Prospectus Supplement.

LOAN UNDERWRITING STANDARDS OF THIRD PARTY ORIGINATORS

     If Third Party Loans are included in a Pool, the underwriting policies and
guidelines of the related Third Party Originators may not be identical to those
set forth above for the Affiliated Originators or for CitiMae. As part of CMI's
process in purchasing Third Party Loans, CMI will review a sample of the Third
Party Loans to determine whether the Third Party Loans would generally conform
to CMI's underwriting standards. The Third Party Loans will be credit scored or
reunderwritten, in each case in whole or in part, by CMI in order to determine
whether the underwriting process for the Third Party Loans adequately assessed
the borrower's ability to repay and the adequacy of the property as collateral,
based on CMI's underwriting standards.

         DELINQUENCY, FORECLOSURE AND LOSS CONSIDERATIONS AND EXPERIENCE

LOSS AND DELINQUENCY CONSIDERATIONS

     There can be no assurance that the foreclosure and delinquency experience
on the Mortgage Loans underlying the CitiMortgageCertificates or the
Certificates will be comparable to that set forth below. The Mortgage Loans
underlying the CitiMortgageCertificates or the Certificates may have a different
range of remaining maturities from those represented by the tables below.
Furthermore, general economic conditions generally affect levels of
delinquencies, defaults and foreclosures. Historically, delinquencies, defaults
and foreclosures do not reach their peak until sometime after the lowest point
in an economic cycle. Finally, the residential real estate market in a
particular area could experience an overall decline in property values such that
the then-current loan-to-value ratios of the Mortgage Loans underlying the
CitiMortgageCertificates or the Certificates could be higher, and could be
substantially higher, than such ratios at origination. In addition, property
values could decline to the point that the amounts owing on the Mortgage Loans
underlying all or part of the CitiMortgageCertificates or the Certificates and
any secondary financing on the related mortgaged properties could become equal
to or greater than the value of such mortgaged properties. In that event, the
actual rate of delinquencies and the number of foreclosures could be higher than
those previously experienced. In addition, the costs and expenses of
foreclosure, together with any damage to or deterioration of the Mortgaged
Property, may result in a determination by the Servicer that foreclosure would
not increase the net proceeds of liquidation available for distribution to
Certificateholders. The Servicer is not required under the Pooling Agreement to
expend its own funds to foreclose on a defaulted Mortgage Loan unless it
generally determines that foreclosure would increase such net proceeds and its
expenditures will be recoverable.

     In recent years, California, the New York Metropolitan Area and several
other regions have experienced significant declines in housing prices. In
addition, California and certain other regions have experienced natural
disasters, such as earthquakes, fires, floods and hurricanes, which have
adversely affected property values in the affected areas. Any direct damage to a
mortgaged property securing a Mortgage Loan caused by such disasters, as well as
any deterioration in housing prices or values or the existence of adverse
economic conditions which adversely affect the ability of mortgagors to make
timely and full payments on Mortgage Loans, may increase the likelihood of
delinquencies, and the likelihood and magnitude of losses, on the Mortgage
Loans, which may result in losses on the Certificates to the extent such losses
are not covered by insurance or any credit enhancement. Such delinquencies or

                                       27
<PAGE>

losses, if occurring, may increase the likelihood of foreclosures and
prepayments on Mortgage Loans, which may in turn have an adverse effect on the
yield of the Certificates or of certain classes of the CitiCertificates.

     The Mortgaged Properties may be located in "anti-deficiency" states where,
in general, a lender providing credit on a one- to four-family property may not
seek a deficiency judgment against the Mortgagor but rather must look solely to
the property for repayment in the event of foreclosure. Each Affiliated
Originator's, CitiMae's and each Third Party Originator's underwriting standards
in all states (including such anti-deficiency states) require underwriting
officers to be satisfied that the value of the property being financed, as
indicated by the appraisal, currently supports the outstanding loan balance. See
APPENDIX A: "THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES--Certain Legal
Aspects of the Mortgage Loans--Anti-Deficiency Legislation and Other Limitations
on Lenders." However, there can be no assurance that property values will not
decline after the Mortgage Loan is originated. 

DELINQUENCY AND FORECLOSURE EXPERIENCE OF AFFILIATED ORIGINATORS' SERVICED
PORTFOLIO

     The delinquency and foreclosure experience on the portfolio of one- to
four-family conventional residential first mortgage loans originated or acquired
by the Affiliated Originators and certain other affiliates of CMI and serviced
by CMI for the periods indicated is set forth in the following table. During the
period covered in the table, this portfolio increased from $34.9 billion on
December 31, 1995 to $37.6 billion on June 30, 1998. CMI's total serviced
portfolio includes both fixed and adjustable interest rate mortgage loans,
including Buydown Mortgage Loans, tiered-payment mortgage loans, loans with
stated maturities of 15 to 30 years and other types of mortgage loans having a
variety of payment characteristics, and includes mortgage loans secured by
mortgaged properties in geographic locations that may not be representative of
the geographic distribution or concentration of the Mortgaged Properties
securing the Mortgage Loans. There can be no assurance that the delinquency and
foreclosure experience set forth below with respect to CMI's total serviced
portfolio will be similar to the results that may be experienced with respect to
the Mortgage Loans underlying the CitiMortgageCertificates or the Certificates.

                DELINQUENCY, FORECLOSURE AND LOSS EXPERIENCE OF
                 AFFILIATED ORIGINATORS' SECURITIZED PORTFOLIO

     The delinquency, foreclosure and loss experience on the one- to four-family
conventional residential first mortgage loans that were originated or acquired
and subsequently sold by the Affiliated Originators, CMSI and certain other
affiliates of CMI pursuant to registration statements under the Securities Act
and serviced by CMI is set forth in the following tables for the periods
indicated. During the period covered in the tables, this group of securitized
mortgage loans decreased from $6.6 billion on December 31, 1995 to $6.0 billion
on June 30, 1998. CMI's total securitized portfolio includes both fixed and
adjustable interest rate mortgage loans, including Buydown Mortgage Loans,
tiered-payment mortgage loans, loans with stated maturities of 15 to 30 years
and other types of mortgage loans having a variety of payment characteristics,

     There can be no assurance that the delinquency, foreclosure or historical
loss experience indicated in the preceding tables with respect to CMI's total
securitized portfolio will be similar to the results that may be experienced
with respect to the Mortgage Loans underlying the CitiMortgageCertificates or
the Certificates. 

DELINQUENCY AND FORECLOSURE EXPERIENCE OF CITIMAE ORIGINATORS' PORTFOLIO

     Historically, a variety of factors including the appreciation of real
estate values have limited CitiMae's loss and delinquency experience on its
portfolio of master serviced mortgage loans. There can be no assurance that
factors beyond CitiMae's control, such as national or local economic conditions
or downturns in the real estate markets of its lending areas, will not result in
increased rates of delinquencies and foreclosure losses in the future.

     If CitiMae Mortgage Loans have an aggregate Adjusted Balance exceeding 10%
of the aggregate Adjusted Balance of the Mortgage Loans in a Pool, the related
Prospectus Supplement will describe the delinquency and foreclosure experience
of CitiMae.

DELINQUENCY AND FORECLOSURE EXPERIENCE OF THIRD PARTY ORIGINATORS' PORTFOLIOS

     If Third Party Loans originated by any one Third Party Originator have an
aggregate Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of
the Mortgage Loans in a Pool, the related Prospectus Supplement will describe
the delinquency and foreclosure experience of such Third Party Originator.

                                    CITICORP

     Citicorp is a holding company incorporated under the laws of Delaware on
December 4, 1967 whose principal subsidiary is Citibank, N.A. The principal
office of Citicorp is located at 399 Park Avenue, New York, New York 10043; its
telephone number is (212) 559-1000.

     Through its subsidiaries and affiliates, including the Issuer, CMI, CFSB,
Citibank and CitiMae, Citicorp is a multinational financial services
organization serving the financial needs of businesses, governments, financial
institutions and individuals in the United States and throughout the world.

     On April 5, 1998, Citicorp, of which the Issuer, CMI, CFSB and Citibank are
wholly owned subsidiaries, and Travelers Group Inc. ("Travelers"), agreed to
merge (the "Merger"). The combined company will be known as Citigroup Inc. The
Merger is subject to customary closing conditions, including regulatory
approvals and the affirmative vote of a majority of the stockholders of each of
Citicorp and Travelers.

                                 USE OF PROCEEDS

     The net proceeds to be received by the Issuer from the sale of the
Certificates are intended to be used for the purpose of originating or
purchasing new residential mortgage loans from the Originators and for other
general corporate purposes, which may include the repayment of indebtedness to
Citicorp, its affiliates or unaffiliated parties. Certificates will be sold in
Series from time to time. The timing and amount of such sales will be dependent
upon a number of factors, including the volume of mortgage loans acquired by the
Issuer, prevailing interest rates, availability of funds and general market
conditions.

                             THE POOLING AGREEMENTS

REPORTS TO CERTIFICATEHOLDERS

     For each Series, the Trustee will include with each distribution to holders
of CitiCertificates, and will send to holders of Residual Certificates, a
statement prepared by the Issuer setting forth the following information (per
Single Certificate, as to (i) through (iii) below):

     (i) to each Certificateholder of a Class of CitiCertificates on which
distributions in reduction of the Stated Amount are then being made, the amount
of such payment which represents a reduction in the Stated Amount and the amount
which represents interest, the amount, if any, which represents losses and the
Stated Amount of a Single Certificate of each Class after giving effect to the
reduction of Stated Amount on such Distribution Date;

     (ii) to each Certificateholder of a Class of CitiCertificates on which a
distribution of interest only is then being made, the amount of such interest
payment and the aggregate Stated Amount of Certificates outstanding of each
Class after giving effect to reductions of Stated Amount, if any, made on such
Distribution Date and on any Special Distribution Date occurring subsequent to
the last such report and after including in the aggregate Stated Amount of
Accrual CitiCertificates outstanding the amount of any accrued interest added to
the Stated Amount thereof on such Distribution Date.

     (iii) to each holder of an Accrual CitiCertificate (but only if such holder
shall not have received on such Distribution Date a distribution of interest
equal to the entire amount of interest accrued on such CitiCertificate during
the Interest Accrual Period with respect to such Distribution Date):

          (A) the information contained in the report delivered pursuant to
     clause (ii) above,

          (B) the interest accrued on a Single Certificate of such Class of
     Accrual CitiCertificates during the Interest Accrual Period with respect to
     such Distribution Date and added to the Stated Amount of such Accrual
     CitiCertificate, and

          (C) the Stated Amount of a Single Certificate of such Class of Accrual
     CitiCertificate after giving effect to the addition thereto of all interest
     accrued thereon during such Interest Accrual Period;

     (iv) the amount of servicing compensation received by the Issuer during the
preceding Reporting Period and such other customary information as the Issuer
deems necessary or desirable to enable Certificateholders to prepare their tax
returns;


                                       31

<PAGE>

     (v) the book value of any real estate acquired by the Pool through
foreclosure or otherwise;

     (vi) the number and aggregate principal amount of Mortgage Loans delinquent
30 days and 60 or more days;

     (vii) the amount remaining under any form of credit support after giving
effect to the declining Amount Available and any payments thereunder and other
amounts charged thereto on the applicable Distribution Date;

     (viii) the aggregate amount received in respect of Mortgage Loans and
Mortgage Certificates during the related Due Period; and

     (ix) the aggregate Adjusted Balance of the Mortgage Loans as of the last
day of the month next preceding the month of such distribution after giving
effect to payments on the Mortgage Loans due on the related Due Date and
Principal Prepayments distributed on the Distribution Date.

     The Issuer will provide Certificateholders that are federally insured
savings and loan associations with certain reports and with access to
information and documentation regarding the Mortgage Loans evidenced by such
Series sufficient to permit such associations to comply with applicable
regulations of the Office of Thrift Supervision (the "OTS"), the successor to
the Federal Home Loan Bank Board. (Section 3.05)

     In addition to the foregoing, the Trustee shall file with the Internal
Revenue Service and applicable state and local taxing authorities and furnish or
make available to Certificateholders such statements or information at the times
and in the manner as may be required by the Code or other tax laws and
regulations in accordance with the Pooling Agreement.

EVIDENCE AS TO COMPLIANCE

     The Pooling Agreement for each Series will provide that a firm of
independent public accountants will furnish to the Trustee and to holders of a
certain percentage of Certificates outstanding (i) on or before March 31, of
each year, beginning with March 31 in the year which begins not less than three
months after the date of the initial issuance of Certificates of that Series, a
statement as to compliance with the Pooling Agreement relating to the servicing
of the Affiliated Mortgage Loans and (ii) on or before September 30, of each
year, beginning with September 30 in the year which begins not less than three
months after the date of initial issuance of Certificates of that Series, a
statement as to compliance with the Pooling Agreement relating to the servicing
of the CitiMae Mortgage Loans. (Section 3.09) The Pooling Agreement will also
provide for delivery to the Trustee and to holders of a certain percentage of
Certificates outstanding on or before March 31 and September 30, respectively,
of each year with respect to the Affiliated Mortgage Loans and September 30 with
respect to the CitiMae Mortgage Loans, beginning with March 31 and September 31,
respectively, in the year which begins not less than three months after the date
of the initial issuance of Certificates of that Series, a statement signed by an
officer of the Issuer to the effect that the Issuer has fulfilled its
obligations under such Pooling Agreement throughout the preceding year or, if
there has been a default in the fulfillment of any such obligation, describing
each such default. (Section 11.01)

     Certificateholders may obtain copies of such statements by request in
writing addressed to the Trustee.

CERTAIN MATTERS REGARDING THE ISSUER AND CITICORP

     The Pooling Agreement for each Series will provide that the Issuer may not
resign from its obligations and duties as servicer thereunder, except upon a
determination evidenced by an opinion of counsel that the Issuer's performance
of such duties is no longer permissible under applicable law or upon the consent
of the Trustee and holders of more than 66-2/3% of the Stated Amount of the
Certificates and of more than 66-2/3% of the Percentage Interests of Residual
Certificates then outstanding. No such resignation will become effective until
the Trustee or a successor servicer has assumed the Issuer's obligations and
duties under such Pooling Agreement. Citicorp's obligations under the Guaranty
for any Series for which a Guaranty is provided for in the related Prospectus
Supplement will, upon issuance thereof, be irrevocable; provided, however, that
the Issuer may substitute in whole or in part another form of credit support for
Citicorp's Guaranty, as described herein. See "--Amendment" below. (Section
6.04)

     The Pooling Agreement will further provide that neither the Issuer nor
Citicorp, if Citicorp has issued a Guaranty, nor any of their respective
directors, officers, employees and agents, shall be under any liability to the
Pool or the Certificateholders for taking any action or for refraining from
taking any action pursuant to the Pooling Agreement, or for errors in judgment;
provided, however, that neither the Issuer nor Citicorp, if Citicorp has issued
a


                                       32

<PAGE>

Guaranty, nor any such person will be protected against any liability which
would otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties thereunder. In addition, the Pooling Agreement will
provide that neither the Issuer nor Citicorp, if Citicorp has issued a Guaranty,
is under any obligation to appear in, prosecute or defend any legal action which
is not incidental to the Issuer's servicing responsibilities under the Pooling
Agreement and which in its opinion may involve it in any expense or liability.
The Issuer may, however, in its discretion undertake any such action which it
may deem necessary or desirable in respect of the Pooling Agreement and the
rights and duties of the parties thereto and the interests of the
Certificateholders thereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom will be expenses, costs and
liabilities of the Pool and the Issuer and Citicorp will be entitled to be
reimbursed therefor out of the Certificate Account. (Section 6.03)

     The Issuer or Citicorp, if Citicorp has issued a Guaranty, and any of its
directors, officers, employees or agents will be indemnified and held harmless
by the Pool against any loss, liability or expense incurred in connection with
any suit in equity, action at law or other proceedings, other than any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
gross negligence in the performance of duties or reckless disregard of
obligations and duties under the Pooling Agreement. (Section 6.03) Any
corporation into which the Issuer may be merged or consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Issuer is a party, or any corporation succeeding to the business of the Issuer,
or any entity, more than 50% of which is owned, directly or indirectly, by
Citicorp, which assumes the obligations of the Issuer, will be the successor of
the Issuer under the Pooling Agreement; provided that, in the event any such
assumption is made, the Issuer will not be released from any of its obligations
thereunder. (Section 6.02) The Issuer may at any time subcontract any duties
under the Pooling Agreement to any entity, including an entity more than 50% of
which is owned, directly or indirectly, by Citicorp. In the event of any such
subcontract, the Issuer will remain responsible for the subcontractor's
performance in accordance with the Pooling Agreement. (Section 6.06)

EVENTS OF DEFAULT

     Events of Default under the Pooling Agreement for each Series will consist
of (i) any failure by the Issuer (a) to distribute to Certificateholders of that
Series any required payment (assuming the Issuer is the paying agent) or (b) to
pay over to the paying agent for distribution to Certificateholders of that
Series any required payment (assuming the Issuer is not the paying agent),
provided that any such failure in (a) or (b) may be remedied by making the
required distribution to Certificateholders (A) within ten business days of
receiving notice of any such failure if the Issuer distributed to
Certificateholders or paid over to the paying agent less than the amount of such
required payment due to an error in calculating the amount of such required
payment and (B) within three business days of receiving notice if the Issuer did
not distribute to Certificateholders or pay over to the paying agent the full
amount in respect of such required payment for any reason other than that set
forth in clause (A) above; (ii) any failure by the Issuer to repurchase any
Mortgage Loan or Mortgage Certificate as required under the Pooling Agreement
which continues unremedied for 60 business days after the giving of written
notice of such failure to the Issuer by the Trustee or to the Issuer and the
Trustee by the holders of Certificates evidencing ownership interests
aggregating not less than 66-2/3% of the Stated Amount of the Certificates;
(iii) any failure by the Issuer duly to observe or perform in any material
respect any of its other covenants or agreements in such Pooling Agreement, if
such failure materially affects the rights of Certificateholders and continues
unremedied for 60 days after the giving of written notice of such failure to the
Issuer by the Trustee, or to the Issuer and the Trustee by the holders of not
less than 66-2/3% of the Stated Amount of the Certificates; and (iv) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceedings and certain actions by the Issuer indicating
its insolvency, reorganization or inability to pay its obligations. (Section
7.01)

RIGHTS UPON EVENT OF DEFAULT

     As long as an Event of Default under the Pooling Agreement for any Series
remains unremedied, the Trustee or holders of not less than 66-2/3% of the
Stated Amount of the Certificates may terminate all of the rights and
obligations of the Issuer under such Pooling Agreement whereupon the Trustee
will succeed to all the responsibilities, duties and liabilities of the Issuer
under such Pooling Agreement and will be entitled to similar compensation
arrangements. The Issuer shall be entitled to payment of certain amounts payable
to it under the Pooling Agreement in respect of services rendered
notwithstanding the termination of its activities as servicer. No such
termination will affect in any manner the issuer's obligations under any credit
support. In the event that the Trustee is unwilling or unable to act as
servicer, it


                                       33

<PAGE>

may appoint, or petition a court of competent jurisdiction for the appointment
of, a housing and home finance institution with a net worth of at least
$5,000,000 to act as successor servicer under such Pooling Agreement. The
Trustee and such successor may agree upon the servicing compensation to be paid,
which in no event may be greater than the Servicing Compensation to the Issuer
under such Pooling Agreement. (Sections 7.01 and 7.02)

     No Certificateholder of any Series will have the right under the applicable
Pooling Agreement to institute any proceeding with respect to such Pooling
Agreement, unless such holder previously has given to the Trustee written notice
of default and unless the holders of Certificates evidencing ownership interests
aggregating not less than 66-2/3% of the Stated Amount of the Certificates have
made written request upon the Trustee to institute such proceeding in its own
name as Trustee thereunder and have offered to the Trustee reasonable indemnity
and the Trustee for 60 days has neglected or refused to institute any such
proceedings. (Section 10.03) However, the Trustee is under no obligation to
exercise any of the trusts or powers vested in it by the Pooling Agreement for
any Series or to make any investigation of matters arising thereunder or to
institute, conduct or defend any litigation thereunder or in relation thereto at
the request, order or direction of any of the Certificateholders, unless such
Certificateholders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred therein or
thereby. (Section 8.02)

AMENDMENT

     The Pooling Agreement and any form of credit support for each Series may be
amended by the Issuer, the issuer of credit support and the Trustee, without
Certificateholder consent, (i) to cure any ambiguity, (ii) to correct or
supplement any provision therein which may be inconsistent with any other
provision therein, (iii) to make any other provisions with respect to matters or
questions arising under such Pooling Agreement or credit support which are not
inconsistent with the provisions of such Pooling Agreement or credit support, as
the case may be, including replacing such credit support (other than any Class
or Classes of subordinated Certificates) in whole or in part by other forms of
credit support as described herein or in the related Prospectus Supplement, (iv)
to comply with any requirements imposed by the Code or any regulations
thereunder, including any requirement relating to maintaining the status of the
Trust (as defined in the related Prospectus Supplement) or applicable portion or
portions of the property thereof as one or more REMICs, as the case may be, or
(v) to establish a "qualified reserve fund" within the meaning of Code Section
860G(a)(7)(B). The Pooling Agreement and any form of credit support for each
Series may also be amended by the Issuer, the issuer of the credit support and
the Trustee, without Certificateholder consent, if the Issuer delivers an
opinion of counsel acceptable to the Trustee to the effect that such amendment
will not materially adversely affect the interests of the Certificateholders.
The Pooling Agreement and any form of credit support for each Series may also be
amended by the Issuer and the Trustee with the consent of the holders of not
less than 66-2/3% of the Stated Amount of the Certificates affected by such
amendment for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of such Pooling Agreement or form of credit
support or modifying in any manner the rights of Certificateholders of that
Series; provided, however, that (i) if any Class of Certificates is affected
differently in any material respect by such amendment than the other Classes,
the consent of the holders of 66-2/3% of the Stated Amount of the Certificates
of such differently affected Class shall be required and (ii) no such amendment
may (i) decrease in any manner the amount of, or delay the timing of, payments
or distributions received on Mortgage Loans or Mortgage Certificates which are
required to be distributed in respect of any such Certificate without the
consent of the holder of such Certificate or (ii) reduce the aforesaid
percentage of Certificates, the holders of which are required to consent to any
such amendment, without the consent of the holders of all Certificates of each
Affected Class then outstanding. (Section 10.01)

LIST OF CERTIFICATEHOLDERS

     If the Trustee is not then the Certificate Registrar, the Issuer will
provide or cause to be provided to the Trustee within 15 days after receipt of
its written request a list of the names and addresses of all Certificateholders
of record of a particular Series as of the most recent record date for payment
of distributions to Certificateholders of that Series. Upon written request of
three or more Certificateholders of record of a Series of Certificates, for
purposes of communicating with other Certificateholders with respect to their
rights under the Pooling Agreement for such Series, the Trustee will afford such
Certificateholders access during business hours to the most recent list of
Certificateholders of that Series held by the Trustee. If such list is as of a
date more than 90 days prior to the date of receipt of such Certificateholders'
request, the Trustee shall promptly request from the Issuer a current list and
will afford such requesting Certificateholders access to such list promptly upon
receipt. (Section 5.05)


                                       34

<PAGE>

     No Pooling Agreement will provide for the holding of any annual or other
meeting of Certificateholders.

TERMINATION; REPURCHASE OF MORTGAGE LOANS AND MORTGAGE CERTIFICATES

     The obligations of the Issuer and the Trustee created by the Pooling
Agreement for each Series will terminate upon the earlier of (a) a complete
liquidation of the Pool as described in the Pooling Agreement and (b) the later
of (i) the maturity or other liquidation of the last Mortgage Loan or Mortgage
Certificate subject thereto and the disposition of all property acquired upon
foreclosure or by deed in lieu of foreclosure of any such Mortgage Loan or
Mortgage Certificate and (ii) the payment to Certificateholders of that Series
of all amounts in the Certificate Account required to be paid to them pursuant
to such Pooling Agreement. In no event, however, will the trust created by any
Pooling Agreement continue beyond the expiration of 21 years from the death of
the last survivor of the descendants of a certain person specified in such
Pooling Agreement living at the date of such Pooling Agreement. For each series
the Issuer will give or cause to be given written notice of termination of the
Pooling Agreement to each Certificateholder, and the final distribution will be
made only upon surrender and the cancellation of the Certificates at an office
or agency of the Trustee specified in the notice of termination. (Section 9.01)
Interest shall not accrue for the period of any delay in the payment of a
Certificate resulting from the failure of a holder to surrender the Certificate
in accordance with such notice.

     The Pooling Agreement for each Series may permit, but not require, the
Issuer or the holders of Residual Certificates to repurchase from the Pool for
such Series, as part of a plan to complete liquidation of the Pool, all
remaining Mortgage Loans and Mortgage Certificates and all property acquired in
respect of such Mortgage Loans and Mortgage Certificates at a price equal to the
sum of (i) 100% of the unpaid principal balance of such Mortgage Loans or
Mortgage Certificates on the first day of the month of repurchase (after giving
effect to payments of principal due on such first day), together with accrued
interest thereon at the then applicable Pass-Through Rate to but not including
the Due Date in the month in which the related distribution is made to
Certificateholders, in the case of a repurchase by the Issuer after subtracting
any unreimbursed payments under the credit support for such Series and any
unreimbursed Voluntary Advances with respect to such Mortgage Loans (other than
such payments or advances with respect to Liquidating Loans and interest in
excess of the applicable Pass-Through Rate), and (ii) the current appraised
value of acquired property. The exercise of such right and the related
liquidation will effect early retirement of the Certificates of that Series, but
such right so to repurchase is subject to (i) the aggregate Adjusted Balance of
the Mortgage Loans or Mortgage Certificates for such Series at the time of
repurchase being equal to or less than the percentage (generally 5%), specified
in the applicable Prospectus Supplement and Pooling Agreement, of the aggregate
Adjusted Balance of such Mortgage Loans or Mortgage Certificates as of the
Cut-Off Date for that Series and (ii) such repurchase and related distributions
(X) constituting a "qualified liquidation" within the meaning of Code Section
860F(a)(4)(A), (Y) not adversely affecting the REMIC status of each Pool and (Z)
not otherwise causing each such Pool to be subject to tax for the taxable year
in which the repurchase occurs or any prior taxable year. (Section 9.01)

DUTIES OF THE TRUSTEE

     The Trustee makes no representations as to the validity or sufficiency of
the Pooling Agreement, the Certificates or of any Mortgage Loan or Mortgage
Certificate or related document, and is not accountable for the use or
application by the Issuer of any funds paid to it in respect of the
Certificates, the Mortgage Loans or the Mortgage Certificates, or deposited into
or withdrawn from the Certificate Account or the Servicing Account by the
Issuer. The Trustee shall have no liability for any losses incurred as a result
of (i) any failure of each Pool to qualify as a REMIC under the Code, (ii) any
termination, inadvertent or otherwise, of each Pool's status as a REMIC or (iii)
any "prohibited transaction" as defined in Code Section 860F(a) unless such
losses were as a result of the Trustee's negligence, bad faith or failure to
perform its duties under the Pooling Agreement. (Section 8.03) If no Event of
Default has occurred, the Trustee is required to perform only those duties
specifically required of it under the Pooling Agreement. However, upon receipt
of the various certificates, reports or other instruments required to be
furnished to it, the Trustee is required to examine them to determine whether
they conform to the requirements of the Pooling Agreement. (Section 8.01)

THE TRUSTEE

     The identity of the commercial bank, savings and loan association or trust
company named as the Trustee for each Series of Certificates will be set forth
in the applicable Prospectus Supplement. The commercial bank, savings


                                       35

<PAGE>

and loan association or trust company serving as Trustee may have normal banking
relationships with the Issuer or the Originators. In addition, for the purpose
of meeting the legal requirements of certain local jurisdictions, the Issuer and
the Trustee acting jointly shall have the power to appoint co-trustees or
separate trustees of all or any part of the Pool relating to a particular Series
of Certificates. In the event of such appointment, all rights, powers, duties
and obligations conferred or imposed upon the Trustee by the Pooling Agreement
relating to such Series shall be conferred or imposed upon the Trustee and each
such separate trustee or co-trustee jointly, or, in any jurisdiction in which
the Trustee shall be incompetent or unqualified to perform certain acts, singly
upon such separate trustee or co-trustee who shall exercise and perform such
rights, powers, duties and obligations solely at the direction of the Trustee.
(Section 8.10) The Trustee may also appoint agents (which may include the Issuer
and its affiliates) to perform any of the responsibilities of the Trustee, which
agents shall have any or all of the rights, powers, duties and obligations of
the Trustee conferred on them by such appointment, provided that the Trustee
shall continue to be responsible for its duties and obligations under the
Pooling Agreement.

     The Trustee may resign at any time, in which event the Issuer will be
obligated to appoint a successor Trustee. The Trustee may also be removed at any
time (i) by the Issuer, (a) if the Trustee ceases to be eligible to continue as
such under the Pooling Agreement or if the Trustee becomes insolvent, (b) if the
Trustee breaches any of its duties under the Pooling Agreement which materially
adversely affects the Certificateholders, (c) if through the performance or
non-performance of certain actions by the Trustee, the rating assigned to the
CitiCertificates would be lowered or (d) if the credit rating of the Trustee is
downgraded to a level which would result in the rating assigned to the
CitiCertificates to be lowered or (ii) by the holders of Certificates evidencing
more than 50% of the current Stated Amount of CitiCertificates then outstanding
and 50% of the Percentage Interests of the Residual Certificates. Upon becoming
aware of such circumstances, the Issuer will be obligated to appoint a successor
Trustee. Any resignation or removal of the Trustee and appointment of a
successor Trustee will not become effective until acceptance of the appointment
by the successor Trustee. (Section 8.07)

                          CERTAIN ERISA CONSIDERATIONS

     The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
imposes certain requirements on those employee benefit plans to which it applies
("Plans") and on those persons who are fiduciaries with respect to such Plans.
In accordance with ERISA's general fiduciary standards, before investing in a
Certificate a Plan fiduciary should determine whether such an investment is
permitted under the governing Plan instruments and is appropriate for the Plan
in view of its overall investment policy and the composition and diversification
of its portfolio. Other provisions of ERISA and the Code prohibit certain
transactions involving the assets of a Plan and persons who have certain
specified relationships to the Plan ("parties in interest" within the meaning of
ERISA or "disqualified persons" within the meaning of the Code). Thus, a Plan
fiduciary considering an investment in Certificates should also consider whether
such an investment might constitute or give rise to a prohibited transaction
under ERISA or the Code. For purposes of the discussion, a person investing on
behalf of an individual retirement account established under Code Section 408
(an "IRA") would be regarded as a fiduciary and the IRA as a Plan.

     An investment in Certificates by a Plan might result in the assets of the
related Pool being deemed to constitute in whole or in part Plan assets, which
in turn might mean that the Plan fiduciary who decided to invest in the
Certificates had delegated asset management responsibility, and that certain
underlying aspects of such investment, including the operation of such Pool,
might be deemed prohibited transactions under ERISA and the Code. Neither ERISA
nor the Code defines "plan assets." The U.S. Department of Labor has published
regulations (the "Regulations") concerning whether or not a Plan's assets would
be deemed to include an interest in the underlying assets of an entity (such as
a Pool) for purposes of certain reporting, disclosure and fiduciary
responsibility requirements, including the prohibited transaction provisions
found in ERISA and the Code, if the Plan acquires an "equity interest" in such
entity (such as by acquiring Certificates). The Issuer cannot predict in advance
whether under the rules set forth in the Regulations an investing Plan's assets
would be deemed to include an interest in the assets of a Pool or be deemed
merely to include its interest in the Certificates, because of the factual
nature of certain of these rules. For example, the Regulations state that the
underlying assets of an entity will not be considered "plan assets" if,
immediately after the most recent acquisition of any equity interest in the
entity, whether or not from the issuer or an underwriter, less than 25% of the
value of each class of equity interest is held by "benefit plan investors,"
which are defined as Plans, IRAs, and employee benefit plans not subject to
ERISA (for example, governmental plans).

     The Regulations provide that if a Plan acquires a "guaranteed governmental
mortgage pool certificate," the Plan's assets include such certificate but do
not include any of the mortgages underlying such certificate. The


                                       36

<PAGE>

Regulations include in the definition of a "guaranteed governmental mortgage
pool certificate" the types of FHLMC Certificates, GNMA Certificates and FNMA
Certificates which may be included in a Pool underlying a Series of
Certificates. Accordingly, even if such Mortgage Certificates included in a Pool
were deemed to be in whole or in part assets of Plan investors, the mortgages
underlying such Mortgage Certificates would not be treated as assets of such
Plans and the operation of the pools containing such underlying mortgages would
not give rise to prohibited transactions.

     U.S. Department of Labor Prohibited Transaction Class Exemption 83-1 for
Certain Transactions Involving Mortgage Pool Investment Trusts ("PTE 83-1")
exempts certain transactions involving the creation, maintenance and termination
of certain residential mortgage pools and the direct or indirect acquisition and
holding of certain residential mortgage pool pass-through certificates by Plans,
from treatment as potential prohibited transactions, whether or not the Plan's
assets would be deemed to include an ownership interest in the mortgages in the
mortgage pool, and whether or not such transactions would otherwise be
prohibited under ERISA. PTE 83-1 sets forth certain "general conditions" and
"specific conditions" to its applicability. The Issuer believes that such
"general conditions" set forth in Section II of PTE 83-1 would be met with
respect to the purchase and holding of Senior Certificates evidencing ownership
interests in a Pool consisting of Real Estate Loans.

     It appears that PTE 83-1 might not apply to the purchase and holding of
Senior Certificates evidencing ownership interests in a Pool consisting of
Cooperative Loans as well as Real Estate Loans, of Certificates which constitute
Residual Certificates, or of Senior Certificates which do not pass through both
principal and interest.

     It is not clear whether PTE 83-1 applies to Senior Certificates evidencing
an interest in a Pool of Mortgage Certificates as opposed to Real Estate Loans;
when offering a Series of such Certificates, if it appears no other ERISA
prohibited transaction exemption is applicable, the Issuer intends to only
include in a Pool Mortgage Certificates which are "guaranteed governmental
mortgage pool certificates," or Mortgage Certificates which themselves would
meet the general conditions of PTE 83-1 if purchased directly by a Plan.
Further, in such circumstances, the Issuer intends to structure the offering of
any such Series of Certificates and the operations of the Pool and to take such
other actions as are both reasonable and appropriate so as to reduce the risk of
the occurrence of ERISA prohibited transactions should PTE 83-1 be held
inapplicable to the acquisition and holding of such Certificates.

     Several underwriters of mortgage-backed securities have applied for and
obtained ERISA prohibited transaction exemptions which are in some respects
broader than PTE 83-1. Such exemptions can only apply to mortgage-backed
securities which, among other conditions, are sold in an offering with respect
to which such underwriter serves as the sole or a managing underwriter, or as a
selling or placement agent. Several other underwriters have applied for similar
exemptions. If such an exemption might be applicable to a Series of
Certificates, the related Prospectus Supplement will refer to such possibility.

     In view of the foregoing, before purchasing any Certificates, a Plan
fiduciary should consult with its counsel and determine whether PTE 83-1 applies
to the creation, maintenance and termination of the Pool and the acquisition and
holding of the Certificates, including whether the appropriate "specific
conditions" set forth in Section I of PTE 83-1 as well as the "general
conditions" of Section II would be met, and should consult the applicable
Prospectus Supplement relating to such Series of Certificates, especially, but
not only, the ERISA discussion, if any. If it is unclear to a Plan fiduciary and
its counsel that PTE 83-1 would apply to the purchase and holding of the
Certificates, because, for example, the Pool includes Mortgage Certificates,
such fiduciary and its counsel should consider whether such Mortgage
Certificates are "guaranteed governmental mortgage pool certificates," whether
in such case PTE 83-1 would be applicable to the indirect acquisition and
holding of the Mortgage Certificates, and whether any other ERISA prohibited
transaction exemption is applicable or necessary.

     Certain affiliates of the Issuer, such as Citicorp, might be considered
"parties in interest" or "disqualified persons" with respect to a Plan. If so,
special caution ought to be exercised before a Plan purchases a Certificate in
such circumstances. Certificates may not be purchased with the assets of a Plan
if an affiliate of the Issuer or of the Trustee of a Pool either: (a) has
investment discretion with respect to the investment of such assets; (b) has
authority or responsibility to give, or regularly gives, investment advice with
respect to such assets for a fee and pursuant to an agreement or understanding
that such advice will serve as a primary basis for investment decisions with
respect to such assets and that such advice will be based on the particular
investment needs of the Plan; or (c) is an employer maintaining or contributing
to such Plan. By agreeing to acquire a Certificate for a Plan, the fiduciary of
any such Plan is representing and warranting to the Underwriter and the Issuer
that the assets of the Plan to be used in connection with such purchase do not
come within (a), (b) or (c) above.

     A governmental plan as defined in Section 3(32) of ERISA is not subject to
ERISA, or Code Section 4975. However, such a governmental plan may be subject to
a federal, state, or local law, which is, to a material extent, similar to the
provisions of ERISA of Code Section 4975 ("Similar Law"). A fiduciary of a
governmental plan should make its own determination as to the need for and the
availability of any exemptive relief under Similar Law.

     The purchase of a Residual Certificate by most varieties of ERISA Plans,
governmental plans, and certain church plans (as defined in section 3(33) of
ERISA) may give rise to "unrelated business taxable income" as described in Code
Sections 511-515 and 860E. Further, prior to the purchase of Residual
Certificates, a prospective purchaser may be required to provide an affidavit to
a transferor that it is not a "disqualified organization," which term as defined
herein includes certain tax-exempt entities not subject to Code Section 511,
including certain governmental plans, as discussed herein under the caption
"CERTAIN FEDERAL INCOME TAX CONSEQUENCES-- Taxation of Residual
Certificates--Tax-Related Restrictions on Transfer of Residual
Certificates--Disqualified Organizations."

     Due to the complexity of the foregoing rules and the penalties imposed upon
persons involved in prohibited transactions, it is particularly important that
potential Plan investors consult with their counsel regarding the consequences
under ERISA of their acquisition and ownership of Certificates. Unless otherwise
specified in the related Prospectus Supplement, no assets of a Plan which is
subject to ERISA may be invested in Subordinated Certificates.

                                LEGAL INVESTMENT

     The Senior Certificates, and if so specified in the related Prospectus
Supplement, the Subordinated Certificates and the Residual Certificates will
constitute "mortgage related securities" for purposes of the Secondary Mortgage
Market Enhancement Act of 1984, as amended ("SMMEA"), so long as (i) they are
rated in one of the two highest rating categories by at least one nationally
recognized statistical rating organization and (ii) are part of a Series
representing interests in a Trust Estate consisting of Mortgage Loans originated
by certain types of originators specified in SMMEA. As "mortgage related
securities," they will be legal investments for persons, trusts, corporations,
partnerships, associations, business trusts and business entities (including,
but not limited to, state-chartered depository institutions, insurance companies
and pension funds), created pursuant to or existing under the laws of the United
States or of any state (including the District of Columbia and Puerto Rico)
whose authorized investments are subject to state regulation to the same extent
that, under applicable law, obligations issued by or guaranteed as to principal
and interest by the United States or any agency or instrumentality thereof
constitute legal investments for such entities. Pursuant to SMMEA, a number of
States enacted legislation, on or before the October 3, 1991 cutoff for such
enactments, limiting to varying extents the ability of certain entities (in
particular, insurance companies) to invest in "mortgage related securities," in
most cases by requiring the affected investors to rely solely upon existing
state law, and not SMMEA. Accordingly, the investors affected by such
legislation will be authorized to invest in the Certificates only to the extent
provided in such legislation.

     SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal in mortgage related
securities without limitation as to the percentage of their assets represented
thereby, federal credit unions may invest in such securities, and national banks
may purchase such securities for their own account without regard to the
limitations generally applicable to investment securities set forth in 12 U.S.C.
ss. 24 (Seventh), subject in each case to such regulations as the applicable
federal regulatory authority may prescribe. In this connection, the Office of
the Comptroller of the Currency (the "OCC") amended 12 C.F.R. Part 1 to
authorize national banks to purchase and sell for their own account, without
limitation as to a percentage of the bank's capital and surplus (but subject to
compliance with certain general standards in 12 C.F.R. ss. 1.5 concerning
"safety and soundness" and retention of credit information), certain "Type IV
securities," defined in 12 C.F.R. ss. 1.2(1) to include certain "residential
mortgage-related securities." As so defined, "residential mortgage-related
security" means, in relevant part, "mortgage related security" within the
meaning of SMMEA. The National Credit Union Administration (the "NCUA") has
adopted rules, codified at 12 C.F.R. Part 703, which permit federal credit
unions to invest in "mortgage related securities" under certain limited
circumstances, other than stripped mortgage related securities, residual
interests in mortgage related securities and commercial mortgage related
securities, unless the credit union has obtained written approval from the NCUA
to participate in the "investment pilot program" described in12 C.F.R. ss.
703.140.


                                       38

     All depository institutions considering an investment in the Certificates
should review the "Supervisory Policy Statement on Investment Securities and
End-User Derivatives Activities" (the "1998 Policy Statement") of the Federal
Financial Institutions Examination Council (the "FFIEC"), which has been adopted
by the Board of Governors of the Federal Reserve System, the Federal Deposit
Insurance Corporation, the OCC and the Office of Thrift Supervision, effective
May 26, 1998, and by the NCUA, effective October 1, 1998. The 1998 Policy
Statement sets forth general guidelines which depository institutions must
follow in managing risks (including market, credit, liquidity, operational
(transaction), and legal risks) applicable to all securities (including mortgage
pass-through securities and mortgage-derivative products) used for investment
purposes. Until October 1, 1998, federal credit unions will still be subject to
the FFIEC's now-superseded "Supervisory Policy Statement on Securities
Activities" dated January 28, 1992, as adopted by the NCUA with certain
modifications, which prohibited depository institutions from investing in
certain "high-risk mortgage securities," except under limited circumstances, and
set forth certain investment practices deemed to be unsuitable for regulated
institutions.

     Institutions whose investment activities are subject to regulation by
federal or state authorities should review rules, policies and guidelines
adopted from time to time by such authorities before purchasing any of the
Certificates, as certain Series, Classes or Subclasses (in particular,
Certificates which are entitled solely or disporportionately to distributions of
principal or interest) may be deemed unsuitable investments, or may otherwise be
restricted, under such rules, policies or guidelines (in certain instances
irrespective of SMMEA).

     The foregoing does not take into consideration the applicability of
statutes, rules, regulations, orders, guidelines or agreements generally
governing investments made by a particular investor, including, but not limited
to, "prudent investor" provisions, percentage-of-assets limits, provisions which
may restrict or prohibit investment in securities which are not
"interest-bearing" or "income-paying," and, with regard to any Certificates
issued in book-entry form, provisions which may restrict or prohibit investments
in securities which are issued in book-entry form.

     Except as to the status of certain Certificates as "mortgage related
securities," no representation is made as to the proper characterization of the
Certificates for legal investment purposes, financial institution regulatory
purposes, or other purposes, or as to the ability of particular investors to
purchase Certificates under applicable legal investment restrictions. The
uncertainties described above (and any unfavorable future determinations
concerning legal investment or financial institution regulatory characteristics
of the Certificates) may adversely affect the liquidity of the Certificates.

     Accordingly, all investors whose investment activities are subject to legal
investment laws and regulations, regulatory capital requirements or review by
regulatory authorities should consult with their own legal advisors in
determining whether and to what extent the Certificates of any Class or Subclass
constitute legal investments or are subject to investment, capital or other
restrictions and, if applicable, whether SMMEA has been overridden in any
jurisdiction relevant to such investor.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

GENERAL

     The following is a general discussion of the anticipated material federal
income tax consequences of the purchase, ownership and disposition of
CitiCertificates and Residual Certificates. The discussion below does not
purport to address all federal income tax consequences that may be applicable to
particular categories of investors, some of which may be subject to special
rules. The authorities on which this discussion is based are subject to change
or differing interpretations, and any such change or interpretation could apply
retroactively. The discussion reflects the applicable provisions of the Code, as
well as regulations (the "REMIC Regulations") promulgated by the U.S. Department
of the Treasury. Investors should consult their own tax advisors in determining
the federal, state, local, and any other tax consequences to them of the
purchase, ownership and disposition of CitiCertificates and Residual
Certificates. For purposes of this tax discussion, references to
"Certificateholder" or "holder" generally mean the beneficial owner of a
CitiCertificate or Residual Certificate.

     With respect to each Series of CitiCertificates and Residual Certificates,
an election will be made to treat the related Trust or one or more segregated
pools of assets therein as one or more REMICs within the meaning of Code Section
860D. If an election is made to treat one or more segregated pools of assets
within the Trust property as a REMIC, references to the "Trust" or the "REMIC"
herein shall be deemed to refer to such portion or portions of the


                                       39

<PAGE>

Trust property. An election may also be made to treat the trust in which
CitiMortgageCertificates with respect to a Series represent an undivided
interest as a REMIC. Qualification as a REMIC requires ongoing compliance with
certain conditions. With respect to each Series of CitiCertificates and Residual
Certificates (and, if applicable, CitiMortgageCertificates), Rona Daniels, Vice
President and Tax Counsel of Citibank, N.A., has advised the Issuer that in her
opinion, assuming (i) the making of an appropriate election, (ii) compliance
with the Pooling Agreement, and (iii) compliance with any changes in the law,
including any amendments to the Code or applicable Treasury regulations
thereunder, the Trust (and, if applicable, the trust relating to the
CitiMortgageCertificates) will qualify as a REMIC. In such case, the
CitiCertificates will be considered to be "regular interests" in the REMIC and
generally will be taxed as if they were newly originated debt instruments, and
the Residual Certificates will be considered to be "residual interests" in the
REMIC. The Prospectus Supplement for each Series of Certificates will indicate
whether more than one REMIC election with respect to the property included in
the related Trust will be made.

STATUS OF CITICERTIFICATES AND RESIDUAL CERTIFICATES

     Certificates held by a domestic building and loan association will
constitute "a regular or residual interest in a REMIC" within the meaning of
Code Section 7701(a)(19)(C)(xi) in the same proportion that the assets of the
REMIC would be treated as "loans . . . secured by an interest in real property
which is . . . residential real property" within the meaning of Code Section
7701(a)(19)(C)(v) or as other assets described in Code Section 7701(a)(19)(C).
Certificates held by a real estate investment trust will constitute "real estate
assets" within the meaning of Code Section 856(c)(4)(A), and interest on the
CitiCertificates and income with respect to Residual Certificates will be
considered "interest on obligations secured by mortgages on real property or on
interests in real property" within the meaning of Code Section 856(c)(3)(B) in
the same proportion that, for both purposes, the assets and income of the REMIC
would be so treated. If at all times 95% or more of the assets of the REMIC
qualify for any of the foregoing treatments, the Certificates will qualify for
the corresponding status in their entirety. It is anticipated that the
Certificates will qualify for the foregoing treatments in their entirety. For
purposes of Code Section 856(c)(4)(A), payments of principal and interest on the
Mortgage Loans that are reinvested pending distribution to holders of
Certificates qualify for such treatment. Where two REMICs are a part of a tiered
structure they will be treated as one REMIC for purposes of the tests described
above respecting asset ownership of more or less than 95%. In addition, if the
assets of the REMIC include Buydown Mortgage Loans, it is possible that the
percentage of such assets constituting "loans . . . secured by an interest in
real property" for purposes of Code Section 7701(a)(19)(C)(v) may be required to
be reduced by the amount of the related buydown subsidy accounts. Certificates
held by a regulated investment company will not constitute "Government
securities" within the meaning of Code Section 851(b)(3)(A)(i). Certificates
held by certain financial institutions will constitute "evidence of
indebtedness" within the meaning of Code Section 582(c)(1). The Small Business
Job Protection Act of 1996 (the "SBJPA of 1996") repealed the reserve method for
bad debts of domestic building and loan associations and mutual savings banks,
and thus has eliminated the asset category of "qualifying real property loans"
in former Code Section 593(d) for taxable years beginning after December 31,
1995. The requirement in the SBJPA of 1996 that such institutions must
"recapture" a portion of their existing bad debt reserves is suspended if a
certain portion of their assets are maintained in "residential loans" under Code
Section 7701(a)(19)(C)(v), but only if such loans were made to acquire,
construct or improve the related real property and not for the purpose of
refinancing. However, no effort will be made to identify the portion of the
Mortgage Loans of any Series meeting this requirement, and no representation is
made in this regard.

QUALIFICATION AS A REMIC

     In order for the Trust to qualify as a REMIC, there must be ongoing
compliance on the part of the Trust with the requirements set forth in the Code.
First, the Trust must fulfill an asset test, which requires that no more than a
de minimis portion of the assets of the Trust (as of the close of the third
calendar month beginning after the Startup Day and at all times thereafter) may
consist of assets other than "qualified mortgages" and "permitted investments."
The REMIC Regulations provide a safe harbor pursuant to which the de minimis
requirement will be met if, at all times, the aggregate adjusted basis of the
nonqualified assets is less than 1% of the aggregate adjusted basis of all the
Trust's assets. An entity that fails to meet the safe harbor may nevertheless
demonstrate that it holds no more than a de minimis amount of nonqualified
assets. A REMIC must also adopt "reasonable arrangements" to prevent its
residual interests from being held by "disqualified organizations" and must
furnish applicable tax information to transferors that violate this requirement.
See "--Taxation of Residual Certificates--Tax-Related Restrictions on Transfer
of Residual Certificates--Disqualified Organizations" below.


                                       40

     A qualified mortgage is any obligation that is principally secured by an
interest in real property and that is either transferred to the REMIC on the
Startup Day or is purchased by the REMIC within a three-month period thereafter
pursuant to a fixed price contract in effect on the Startup Day. Qualified
mortgages include whole mortgage loans or stripped portions thereof,
certificates of beneficial ownership in a grantor trust that holds mortgage
loans, such as the Mortgage Certificates, and regular interests in another
REMIC, such as Mortgage Certificates in a trust as to which a REMIC election has
been made. The REMIC Regulations specify that loans secured by timeshare
interests and shares held by a tenant stockholder in a cooperative housing
corporation can be qualified mortgages. A qualified mortgage includes a
qualified replacement mortgage, which is any property that would have been
treated as a qualified mortgage if it were transferred to the REMIC on the
Startup Day and that is received either (i) in exchange for any qualified
mortgage within a three-month period thereafter, or (ii) in exchange for a
"defective obligation" within a two-year period thereafter. A "defective
obligation" includes (i) a mortgage in default or as to which default is
reasonably foreseeable, (ii) a mortgage as to which a customary representation
or warranty made at the time of transfer to the REMIC has been breached, (iii) a
mortgage that was fraudulently procured by the mortgagor, and (iv) a mortgage
that was not in fact principally secured by real property (but only if such
mortgage is disposed of within 90 days of discovery). A Mortgage Loan that is
"defective" as described in clause (iv) that is not sold or, if within two years
of the Startup Day, exchanged within 90 days of discovery, ceases to be a
qualified mortgage after such 90 day period.

     Permitted investments include cash flow investments, qualified reserve
assets, and foreclosure property. A cash flow investment is an investment,
earning a return in the nature of interest, of amounts received on or with
respect to qualified mortgages for a temporary period, not exceeding thirteen
months, until the next scheduled distribution to holders of interests in the
REMIC. A qualified reserve asset is any intangible property held for investment
that is part of any reasonably required reserve maintained by the REMIC to
provide for payments of expenses of the REMIC or to provide additional security
for payments due on the regular or residual interests that otherwise may be
delayed or defaulted upon because of a default or delinquency on the qualified
mortgages, lower than expected reinvestment returns, prepayment interest
shortfalls and certain other contingencies. The reserve fund will be
disqualified if more than 30% of the gross income from the assets in such fund
for the year is derived from the sale or other disposition of property held for
less than three months, unless required to prevent a default on the regular
interests caused by a default on one or more qualified mortgages. A reserve fund
must be reduced "promptly and appropriately" as payments on the Mortgage Loans
are received. Foreclosure property is real property acquired by the REMIC in
connection with the default or imminent default of a qualified mortgage and
generally not held beyond the close of the third calendar year following the
year of acquisition, with a possible extension granted by the Internal Revenue
Service.

     In addition to the foregoing requirements, the various interests in a REMIC
also must meet certain requirements. All of the interests in a REMIC must be
either of the following: (i) one or more classes of regular interests or (ii) a
single class of residual interests on which distributions, if any, are made pro
rata. A regular interest is an interest in a REMIC that is issued on the Startup
Day with fixed terms, is designated as a regular interest, and unconditionally
entitles the holder to receive a specified principal amount (or other similar
amount), and provides that interest payments (or other similar amounts), if any,
at or before maturity either are payable based on a fixed rate or a qualified
variable rate, or consist of a specified, nonvarying portion of the interest
payments on qualified mortgages. Such a specified portion may consist of a fixed
number of basis points, a fixed percentage of the total interest or the
difference between fixed and qualified variable rates on some or all of the
qualified mortgages. The specified principal amount of a regular interest that
provides for interest payments consisting of a specified, nonvarying portion of
interest payments on qualified mortgages may be zero. A residual interest is an
interest in a REMIC other than a regular interest that is issued on the Startup
Day and is designated as a residual interest. An interest in a REMIC may be
treated as a regular interest even if payments of principal with respect to such
interest are subordinated to payments on other regular interests or the residual
interest in the REMIC, and are dependent on the absence of defaults or
delinquencies on qualified mortgages or permitted investments, lower than
reasonably expected returns on permitted investments, unanticipated expenses
incurred by the REMIC or prepayment interest shortfalls. Accordingly, the
CitiCertificates of a Series will constitute one or more classes of regular
interests, and the Residual Certificates of that Series will constitute a single
class of residual interests on which distributions are made pro rata.

     If an entity, such as the Trust, fails to comply with one or more of the
ongoing requirements of the Code for REMIC status during any taxable year, the
Code provides that the entity will not be treated as a REMIC for such year and
thereafter. In this event, an entity with multiple classes of ownership
interests may be treated as a separate


                                       41

<PAGE>

association taxable as a corporation under Treasury regulations, and the
CitiCertificates may be treated as equity interests therein. The Code authorizes
the Treasury Department to issue regulations that address situations where
failure to meet one or more of the requirements for REMIC status occurs
inadvertently and in good faith, and disqualification of the REMIC would occur
absent regulatory relief. Investors should be aware, however, that the
Conference Committee Report to the Tax Reform Act of 1986 (the "1986 Act")
indicates that the regulatory relief may be accompanied by sanctions, such as
the imposition of a corporate tax on all or a portion of the REMIC's income for
the period of time in which the requirements for REMIC status are not satisfied.

TAXATION OF CITICERTIFICATES

  General

     In general, interest, original issue discount, and market discount on a
CitiCertificate will be treated as ordinary income to a Certificateholder, and
distributions in reduction of Stated Amount of a CitiCertificate will be treated
as a return of capital to the extent of the Certificateholder's basis in the
CitiCertificate. Each Certificateholder must use the accrual method of
accounting with regard to CitiCertificates, regardless of the method of
accounting otherwise used by such Certificateholder.

  Original Issue Discount

     All Accrual CitiCertificates will be, and certain of the CitiCertificates
of other Classes of a Series may be, issued with "original issue discount"
within the meaning of Code Section 1273(a). Holders of any Class of
CitiCertificates having original issue discount generally must include original
issue discount in ordinary income for federal income tax purposes as it accrues,
in accordance with a constant yield method that takes into account the
compounding of interest, in advance of receipt of the cash attributable to such
income. The following discussion is based in part on temporary and final
Treasury regulations issued on February 2, 1994, as amended on April 14, 1996
(the "OID Regulations") under Code Sections 1271 through 1273 and 1275 and in
part on the provisions of the 1986 Act. Holders of CitiCertificates should be
aware, however, that the OID Regulations do not adequately address certain
issues relevant to prepayable securities, such as the CitiCertificates. To the
extent such issues are not addressed in such regulations, the Issuer intends to
apply the methodology described in the Conference Committee Report to the 1986
Act. No assurance can be provided that the Internal Revenue Service will not
take a different position as to those matters not currently addressed by the OID
Regulations. Moreover, the OID Regulations include an anti-abuse rule allowing
the Internal Revenue Service to apply or depart from the OID Regulations where
necessary or appropriate to ensure a reasonable tax result in light of the
applicable statutory provisions. A tax result will not be considered
unreasonable under the anti-abuse rule in the absence of a substantial effect on
the present value of a taxpayer's tax liability. Investors are advised to
consult their own tax advisors as to the discussion herein and the appropriate
method for reporting interest and original issue discount with respect to the
CitiCertificates.

     Each CitiCertificate (except to the extent described below with respect to
a CitiCertificate on which distributions in reduction of Stated Amount are made
in a single installment by lots of a specified Stated Amount upon the request of
a Certificateholder or by random lot (a "Retail Class CitiCertificate")) will be
treated as a single installment obligation for purposes of determining the
original issue discount includible in a Certificateholder's income. The total
amount of original issue discount on a CitiCertificate is the excess of the
"stated redemption price at maturity" of the CitiCertificate over its "issue
price." The issue price of a Class of CitiCertificates generally is the first
price at which a substantial amount of CitiCertificates of such Class is sold to
the public (excluding bond houses, brokers and underwriters). Although unclear
under the OID Regulations, the Issuer intends to treat the issue price of a
Class as to which there is no substantial sale as of the issue date or that is
retained by the Issuer as the fair market value of that Class as of the issue
date. The issue price of a CitiCertificate also includes any amount paid by the
initial Certificateholder for accrued interest that relates to a period prior to
the issue date of the CitiCertificate, unless the CitiCertificateholder elects
on its federal income tax return to exclude such amount from the issue price and
to recover it on the first Distribution Date. The stated redemption price at
maturity of a CitiCertificate always includes its Initial Stated Amount. The
stated redemption price at maturity generally will not include distributions of
interest if such interest distributions constitute "qualified stated interest."
Under the OID Regulations, qualified stated interest generally means interest
payable at a single fixed rate or a qualified variable rate (as described
below), provided that such interest distributions are unconditionally
distributable at intervals of one year or less during the entire term of the
CitiCertificates. Because there is no penalty or default remedy in the case of
nonpayment of interest with respect to a


                                       42

<PAGE>

CitiCertificate, it is possible that no interest on any Class of
CitiCertificates will be treated as qualified stated interest. However, except
as provided in the following three sentences or in the applicable Prospectus
Supplement, because the underlying Mortgage Loans provide for remedies in the
event of default, the Issuer intends to treat interest with respect to the
CitiCertificates as qualified stated interest. No distributions on an Accrual
CitiCertificate, or on other CitiCertificates with respect to which interest
distributions may be deferred and added to the Stated Amount, will constitute
qualified stated interest and, accordingly, the stated redemption price at
maturity of such CitiCertificates includes not only their Initial Stated Amount
but also all other distributions (whether denominated as accrued interest or
current interest) to be received thereon. Likewise, the Issuer intends to treat
an "interest only" class or a class on which interest is substantially
disproportionate to its principal amount (a so-called "super-premium" class) as
having no qualified stated interest. Where the interval between the issue date
and the first Distribution Date on a CitiCertificate is shorter than the
interval between subsequent Distribution Dates, the interest attributable to the
additional days will be included in the stated redemption price at maturity.

     Under a de minimis rule, original issue discount on a CitiCertificate will
be considered to be zero if such original issue discount is less than 0.25% of
the stated redemption price at maturity of the CitiCertificate multiplied by the
weighted average maturity of the CitiCertificate. For this purpose, the weighted
average maturity of the CitiCertificate is computed as the sum of the amounts
determined by multiplying the number of full years (i.e., rounding down partial
years) from the issue date until each return of stated redemption price at
maturity is scheduled to be made by a fraction, the numerator of which is the
amount of each return of stated redemption price at maturity and the denominator
of which is the stated redemption price at maturity of the CitiCertificate. The
Conference Committee Report to the 1986 Act provides that the schedule of such
distributions should be determined in accordance with the assumed rate of
prepayment of the Mortgage Loans and Mortgage Certificates included in the Trust
(the "Prepayment Assumption") and the anticipated reinvestment rate, if any,
used in pricing the CitiCertificates. The Prepayment Assumption with respect to
a Series of CitiCertificates will be set forth in the related Prospectus
Supplement. Holders of CitiCertificates generally must report de minimis
original issue discount pro rata as distributions of stated redemption price at
maturity are received, and such income will be capital gain if the
CitiCertificate is held as a capital asset. However, holders of CitiCertificates
may elect to accrue all de minimis original issue discount, as well as market
discount and market premium, under the constant yield method. See "--Election to
Treat All Interest Under the Constant Yield Method" below.

     A holder of a CitiCertificate generally must include in gross income for
any taxable year the sum of the "daily portions", as defined below, of the
original issue discount on the CitiCertificate accrued during an accrual period
for each day on which it holds the CitiCertificate, including the date of
purchase but excluding the date of disposition. The Issuer will treat the
monthly period ending on the day before each Distribution Date as the accrual
period. With respect to each CitiCertificate, a calculation will be made of the
original issue discount that accrues during each successive full accrual period
(or shorter period from the date of original issue) that ends on the day before
the related Distribution Date on the CitiCertificate. The Conference Committee
Report to the 1986 Act states that the rate of accrual of original issue
discount is intended to be based on the Prepayment Assumption. The original
issue discount accruing in a full accrual period on a CitiCertificate would be
the excess, if any, of (i) the sum of (a) the present value of all of the
remaining distributions to be made on the CitiCertificate as of the end of that
accrual period and (b) the distributions made on the CitiCertificate during the
accrual period that are included in the CitiCertificate's stated redemption
price at maturity, over (ii) the adjusted issue price of the CitiCertificate at
the beginning of the accrual period. The present value of the remaining
distributions referred to in the preceding sentence is calculated based on (i)
the yield to maturity of the CitiCertificate as of the Startup Day, (ii) events
(including actual prepayments) that have occurred prior to the end of the
accrual period and (iii) the Prepayment Assumption. For these purposes, the
adjusted issue price of a CitiCertificate at the beginning of any accrual period
equals the issue price of the CitiCertificate, increased by the aggregate amount
of original issue discount with respect to the CitiCertificate that accrued in
all prior accrual periods and reduced by the amount of distributions included in
the CitiCertificate's stated redemption price at maturity that were made on the
CitiCertificate attributable to such prior periods. The original issue discount
accruing during any accrual period (as determined in this paragraph) will then
be divided by the number of days in the period to determine the daily portion of
original issue discount for each day in the period. With respect to an initial
accrual period that is shorter than a full accrual period, the daily portions of
original issue discount must be determined according to an appropriate
allocation under any reasonable method.

     Under the method described above, the daily portions of original issue
discount required to be included in income by a holder of a CitiCertificate
generally will increase to take into account prepayments on the CitiCertificates


                                       43

<PAGE>

as a result of prepayments on the Mortgage Loans underlying the Mortgage
Certificates or Mortgage Loans that exceed the Prepayment Assumption, and
generally will decrease (but not below zero for any period) if the prepayments
on the Mortgage Loans underlying the Mortgage Certificates or Mortgage Loans are
slower than the Prepayment Assumption. An increase in prepayments on the
Mortgage Loans with respect to a Series can result in both a change in the
priority of principal payments with respect to certain Classes of
CitiCertificates and either an increase or decrease in the daily portions of
original issue discount with respect to such CitiCertificates.

     In the case of a Retail Class CitiCertificate, the Issuer intends to
determine the yield to maturity of such CitiCertificate based upon the
anticipated payment characteristics of the Class as a whole under the Prepayment
Assumption. In general, the original issue discount accruing on each Retail
Class CitiCertificate in a full accrual period would be its allocable share of
the original issue discount with respect to the entire Class, as determined in
accordance with the preceding paragraph. However, in the case of a distribution
in reduction of the entire Stated Amount of any Retail Class CitiCertificate (or
portion of such Stated Amount), (a) the remaining unaccrued original issue
discount allocable to such CitiCertificate (or to such portion) will accrue at
the time of such distribution, and (b) the accrual of original issue discount
allocable to each remaining CitiCertificate of such Class (or the remaining
Stated Amount of a Retail Class CitiCertificate after a distribution in
reduction of Stated Amount has been received) will be adjusted by reducing the
present value of the remaining payments on such Class and the adjusted issue
price of such Class to the extent attributable to the portion of the Stated
Amount that was distributed. The Issuer believes that the foregoing treatment is
consistent with the "pro rata prepayment" rules of the OID Regulations, but with
the rate of accrual of original issue discount determined based on the
Prepayment Assumption for the Class as a whole. Investors are advised to consult
their tax advisors as to this treatment.

  Acquisition Premium

     A purchaser of a CitiCertificate at a price greater than its adjusted issue
price but less than its stated redemption price at maturity will be required to
include in gross income the daily portions of the original issue discount on the
CitiCertificate pro rata by a fraction, the numerator of which is the excess of
its purchase price over such adjusted issue price and the denominator of which
is the excess of the remaining stated redemption price at maturity over the
adjusted issue price. Alternatively, such a subsequent purchaser may elect to
treat all such acquisition premium under the constant yield method, as described
under the heading "--Election to Treat All Interest Under the Constant Yield
Method" below.

  Variable Rate CitiCertificates

     CitiCertificates may provide for interest based on a variable rate
("Variable Rate CitiCertificates"). Under the OID Regulations, interest is
treated as payable at a variable rate if, generally, (i) the issue price does
not exceed the original principal balance by more than a specified amount and
(ii) the interest compounds or is payable at least annually at current values of
(a) one or more "qualified floating rates," (b) a single fixed rate and one or
more qualified floating rates, (c) a single "objective rate," or (d) a single
fixed rate and a single objective rate that is a "qualified inverse floating
rate." A floating rate is a qualified floating rate if variations in the rate
can reasonably be expected to measure contemporaneous variations in the cost of
newly borrowed funds, where such rate is subject to a multiple that is greater
than 0.65 but not greater than 1.35. Such rate may also be increased or
decreased by a fixed spread or subject to a fixed cap or floor, or a cap or
floor that is not reasonably expected as of the issue date to affect the yield
of the instrument significantly. An objective rate is any rate (other than a
qualified floating rate) that is determined using a single fixed formula and
that is based on objective financial or economic information, provided that such
information is not (i) within the control of the issuer or a related party or
(ii) unique to the circumstances of the issuer or a related party. A qualified
inverse floating rate is a rate equal to a fixed rate minus a qualified floating
rate that inversely reflects contemporaneous variations in the cost of newly
borrowed funds; an inverse floating rate that is not a qualified inverse
floating rate may nevertheless be an objective rate. A Class of CitiCertificates
may be issued under this Prospectus that does not have a variable rate under the
foregoing rules, for example, a Class that bears different rates at different
times during the period it is outstanding such that it is considered
significantly "front-loaded" or "back-loaded" within the meaning of the OID
Regulations. It is possible that such a Class may be considered to bear
"contingent interest" within the meaning of the OID Regulations. The OID
Regulations, as they relate to the treatment of contingent interest, are by
their terms not applicable to CitiCertificates. However, if final regulations
dealing with contingent interest with respect to CitiCertificates apply the same
principles as the OID Regulations, such regulations may lead to different timing
of income inclusion than would be the case under the OID


                                       44

<PAGE>

Regulations. Furthermore, application of such principles could lead to the
characterization of gain on the sale of contingent interest CitiCertificates as
ordinary income. Investors should consult their tax advisors regarding the
appropriate treatment of any CitiCertificates that do not pay interest at a
fixed rate or variable rate as described in this paragraph.

     Under the REMIC Regulations, a CitiCertificate (i) bearing a rate that
qualifies as a variable rate under the OID Regulations that is tied to current
values of a variable rate (or the highest, lowest or average of two or more
variable rates, including a rate based on the average cost of funds of one or
more financial institutions), or a positive or negative multiple of such a rate
(plus or minus a specified number of basis points) or that represents a weighted
average of rates on some or all of the Mortgage Loans that bear either a fixed
rate or a variable rate, including such a rate that is subject to one or more
caps or floors, or (ii) bearing one or more such variable rates for one or more
periods, and a different variable rate or fixed rate for other periods,
qualifies as a regular interest in a REMIC. Accordingly, unless otherwise
indicated in the applicable Prospectus Supplement, the Issuer intends to treat
CitiCertificates that qualify as regular interests under this rule in the same
manner as obligations bearing a variable rate for original issue discount
reporting purposes.

     The amount of original issue discount with respect to a CitiCertificate
bearing a variable rate of interest will accrue in the manner described above
under "Original Issue Discount", with the yield to maturity and future
distributions on such CitiCertificate generally to be determined by assuming
that interest will be payable for the life of the CitiCertificate based on the
initial rate (or, if different, the value of the applicable variable rate as of
the pricing date). Unless otherwise specified in the applicable Prospectus
Supplement, the Issuer intends to treat such variable interest as qualified
stated interest, other than variable interest on an interest-only or
super-premium Class, which will be treated as non-qualified stated interest
includible in the stated redemption price at maturity. Ordinary income
reportable for any period will be adjusted based on subsequent changes in the
applicable interest rate index.

     Although unclear under the OID Regulations, the Issuer intends to treat
CitiCertificates bearing an interest rate that is a weighted average of the net
interest rates on Mortgage Loans having fixed or adjustable rates as having
qualified stated interest. In the case of adjustable rate Mortgage Loans, the
applicable index used to compute interest on the Mortgage Loans in effect on the
pricing date (or possibly the issue date) will be deemed to be in effect
beginning with the period in which the first weighted average adjustment date
occurring after the issue date occurs. Adjustments will be made in each accrual
period either increasing or decreasing the amount of ordinary income reportable
to reflect the actual Stated Rate on the CitiCertificates.

  Deferred Interest

     Any Deferred Interest (as defined in the Prospectus Supplement with respect
to a Series) that accrues with respect to a Class of CitiCertificates will
constitute income to the holders of such CitiCertificates prior to the time
distributions of cash with respect to such Deferred Interest are made. Under the
OID Regulations, all interest payments on CitiCertificates that may have
Deferred Interest must be treated as non-qualified stated interest payments and
included in the stated redemption price at maturity of the CitiCertificates in
computing original issue discount thereon.

  Market Discount

     A purchaser of a CitiCertificate also may be subject to the market discount
rules of Code Sections 1276 through 1278. Under these Code sections and the
principles applied by the OID Regulations in the context of original issue
discount, "market discount" is the amount by which the purchaser's original
basis in the CitiCertificate (i) is exceeded by the then-current principal
amount of the CitiCertificate, or (ii) in the case of a CitiCertificate having
original issue discount, is exceeded by the adjusted issue price of such
CitiCertificate at the time of purchase, as described above. Such purchaser
generally will be required to recognize ordinary income to the extent of accrued
market discount on such CitiCertificate as distributions includible in the
stated redemption price at maturity thereof are received, in an amount not
exceeding any such distribution. Such market discount would accrue in a manner
to be provided in Treasury regulations and should take into account the
Prepayment Assumption. The Conference Committee Report of the 1986 Act provides
that until such regulations are issued, such market discount would accrue either
(i) on the basis of a constant interest rate, or (ii) in the ratio of stated
interest allocable to the relevant period to the sum of the interest for such
period plus the remaining interest as of the end of such period, or in the case
of a CitiCertificate issued with original issue discount, in the ratio of
original issue discount accrued for the relevant


                                       45

<PAGE>

period to the sum of the original issue discount accrued for such period plus
the remaining original issue discount as of the end of such period. Such
purchaser also generally will be required to treat a portion of any gain on a
sale or exchange of the CitiCertificate as ordinary income to the extent of the
market discount accrued to the date of disposition under one of the foregoing
methods, less any accrued market discount previously reported as ordinary income
as partial distributions in reduction of the stated redemption price at maturity
were received. Such purchaser also will be required to defer deduction of a
portion of the interest expense attributable to any indebtedness incurred or
continued to purchase or carry the CitiCertificate. The deferred portion of the
interest expense would not exceed the accrued market discount on the
CitiCertificate for the taxable year. Any such deferred interest expense is, in
general, allowed as a deduction not later than the year in which the related
market discount income is recognized or the CitiCertificate is disposed of. As
an alternative to the inclusion of market discount in income on the foregoing
basis, the holder may elect to include market discount in income currently as it
accrues on all market discount instruments acquired by such holder in that
taxable year or thereafter, in which case the interest deferral rule will not
apply. See "--Election to Treat All Interest Under the Constant Yield Method"
below regarding an alternative manner in which such election may be deemed to be
made.

     By analogy to the OID Regulations, market discount with respect to a
CitiCertificate will be considered to be zero if such market discount is less
than 0.25% of the remaining stated redemption price at maturity of such
CitiCertificate multiplied by the weighted average maturity of the
CitiCertificate (determined as described above in the third paragraph under
"Original Issue Discount") remaining after the date of purchase. It appears that
de minimis market discount would be reported in a manner similar to de minimis
original issue discount. See "Original Issue Discount" above. Treasury
regulations implementing the market discount rules have not yet been issued, and
therefore investors should consult their own tax advisors regarding the
application of these rules. Investors should also consult Revenue Procedure
92-67 concerning the elections to include market discount in income currently
and to accrue market discount on the basis of the constant yield method.

  Premium

     A CitiCertificate purchased at a cost greater than its remaining stated
redemption price at maturity generally is considered to be purchased at a
premium. If a holder holds such CitiCertificate as a "capital asset" within the
meaning of Code Section 1221, the holder may elect under Code Section 171 to
amortize such premium under the constant yield method. Such election will apply
to all debt obligations acquired at a premium by the holder of a CitiCertificate
held in that taxable year or thereafter, unless revoked with the permission of
the Internal Revenue Service. Final Treasury regulations issued under Code
Section 171 do not by their terms apply to prepayable debt instrument such as
the CitiCertificates. However, the Conference Committee Report to the 1986 Act
indicates a Congressional intent that the same rules that will apply to the
accrual of market discount on installment obligations will also apply in
amortizing bond premium under Code Section 171 on installment obligations such
as the CitiCertificates, although it is unclear whether the alternatives to the
constant yield method described above under "--Market Discount" are available.
Amortizable bond premium will be treated as an offset to interest income on a
CitiCertificate, rather than a separate deduction item. See "--Election to Treat
All Interest Under the Constant Yield Method" below regarding an alternative
manner in which the Code Section 171 election may be deemed to be made.

  Treatment of Losses

     Holders of CitiCertificates will be required to report income with respect
to the CitiCertificates on the accrual method of accounting, without giving
effect to delays or reductions in distributions attributable to defaults or
delinquencies on the Mortgage Loans, except to the extent it can be established
that such losses are uncollectible. Accordingly, the holder of a
CitiCertificate, particularly a Subordinated Certificate, may have income or may
incur a diminution in cash flow as a result of a default or delinquency, but may
not be able to take a deduction (subject to the discussion below) for the
corresponding loss until a subsequent taxable year. In this regard, investors
are cautioned that while they may generally cease to accrue interest income if
it reasonably appears that the interest will be uncollectible, the Internal
Revenue Service may take the position that original issue discount must continue
to be accrued in spite of its uncollectibility until the debt instrument is
disposed of in a taxable transaction or becomes worthless in accordance with the
rules of Code Section 166.

     To the extent the rules of Code Section 166 regarding bad debts are
applicable, it appears that holders of CitiCertificates that are corporations or
that otherwise hold the CitiCertificates in connection with a trade or business


                                       46

<PAGE>

should in general be allowed to deduct as an ordinary loss such loss with
respect to principal sustained during the taxable year on account of any such
CitiCertificates becoming wholly or partially worthless, and that, in general,
holders of CitiCertificates that are not corporations and do not hold the
CitiCertificates in connection with a trade or business will be allowed to
deduct as a short term capital loss any loss sustained during the taxable year
on account of a portion of any such CitiCertificates becoming wholly worthless.
Although the matter is not free from doubt, such non-corporate holders of
CitiCertificates should be allowed a bad debt deduction at such time as a loss
is allocated to such Class of CitiCertificates to reflect losses resulting from
any liquidated Mortgage Loans. The Internal Revenue Service, however, could take
the position that non-corporate holders will be allowed a bad debt deduction to
reflect such losses only after all the Mortgage Loans remaining in the Trust
have been liquidated or the applicable Class of CitiCertificates has been
otherwise retired. The Internal Revenue Service could also assert that losses on
the CitiCertificates are deductible on some other method that may defer such
deductions for all holders, such as reducing future cash flow for purposes of
computing original issue discount. This may have the effect of creating
"negative" original issue discount which would be deductible only against future
positive original issue discount or otherwise upon termination of the Class.
Holders of CitiCertificates are urged to consult their own tax advisors
regarding the appropriate timing, amount and character of any loss sustained
with respect to such CitiCertificates. While losses attributable to interest
previously reported as income should be deductible as ordinary losses by both
corporate and non-corporate holders, the Internal Revenue Service may take the
position that losses attributable to accrued original issue discount may only be
deducted as short-term capital losses by non-corporate holders not engaged in a
trade or business. Special loss rules are applicable to banks and thrift
institutions, including rules regarding reserves for bad debts. Such taxpayers
are advised to consult their tax advisors regarding the treatment of losses on
CitiCertificates.

  Election to Treat All Interest Under the Constant Yield Method

     A holder of a debt instrument such as a CitiCertificate may elect to treat
all interest that accrues on the instrument using the constant yield method,
with none of the interest being treated as qualified stated interest. For
purposes of applying the constant yield method to a debt instrument subject to
such an election, (i) "interest" includes stated interest, original issue
discount, de minimis original issue discount, market discount and de minimis
market discount, as adjusted by any amortizable bond premium or acquisition
premium and (ii) the debt instrument is treated as if the instrument were issued
on the holder's acquisition date in the amount of the holder's adjusted basis
immediately after acquisition. It is unclear whether, for this purpose, the
initial prepayment assumption would continue to apply or if a new prepayment
assumption as of the date of the holder's acquisition would apply. A holder
generally may make such an election on an instrument by instrument basis or for
a class or group of debt instruments. However, if the holder makes such an
election with respect to a debt instrument with amortizable bond premium or with
market discount, the holder is deemed to have made elections to amortize bond
premium or to report market discount income currently as it accrues under the
constant yield method, respectively, for all premium bonds held or market
discount bonds acquired by the holder in the same taxable year or thereafter.
The election is made on the holder's federal income tax return for the year in
which the debt instrument is acquired and is irrevocable except with the
approval of the Internal Revenue Service. Investors should consult their own tax
advisors regarding the advisability of making such an election.

  Sale or Exchange of CitiCertificates

     If a holder sells or exchanges a CitiCertificate, the holder will recognize
gain or loss equal to the difference, if any, between the amount received and
its adjusted basis in the CitiCertificate. The adjusted basis of a
CitiCertificate generally will equal the cost of the CitiCertificate to the
seller, increased by any original issue discount or market discount previously
included in the seller's gross income with respect to the CitiCertificate, and
reduced by the distributions in reduction of the Stated Amount of the
CitiCertificate that were previously received by the seller, by any amortized
premium and by any deductible losses.

     Except as described above with respect to market discount, and except as
provided in this paragraph, any gain or loss on the sale or exchange of a
CitiCertificate realized by an investor who holds the CitiCertificate as a
capital asset (within the meaning of Code Section 1221) will be capital gain or
loss and will be long-term, mid-term or short-term depending on whether the
CitiCertificate has been held for the applicable holding period (described
below). Such gain will be treated as ordinary income (i) if a CitiCertificate is
held as part of a "conversion transaction" as defined in Code Section 1258(c),
up to the amount of interest that would have accrued on the holder's net
investment in the conversion transaction at 120% of the appropriate applicable
Federal rate under Code Section 1274(d) in effect at the time the holder entered
into the transaction minus any amount previously treated as ordinary income with
respect to


                                       47

<PAGE>

any prior disposition of property that was held as a part of such transaction,
(ii) in the case of a non-corporate taxpayer, to the extent such taxpayer has
made an election under Code Section 163(d)(4) to have net capital gains taxed as
investment income at ordinary income rates, or (iii) to the extent that such
gain does not exceed the excess, if any, of (a) the amount that would have been
includible in the gross income of the holder if its yield on such
CitiCertificate were 110% of the applicable Federal rate as of the date of
purchase, over (b) the amount of income actually includible in the gross income
of such holder with respect to such CitiCertificate. In addition, gain or loss
recognized from the sale of a CitiCertificate by certain banks or thrift
institutions will be treated as ordinary income or loss pursuant to Code Section
582(c). In general, short-term capital gains of certain non-corporate taxpayers
are subject to the same maximum tax rate of 39.6% as the ordinary income of such
taxpayers for property held for not more than one year, and long-term capital
gains of such taxpayers are subject to a maximum tax rate of 20% for property
held for more than one year. The maximum tax rate for corporations is the same
with respect to both ordinary income and capital gains.

TAXATION OF RESIDUAL CERTIFICATES

  Taxation of REMIC Income

     Generally, the "daily portions" of REMIC taxable income or net loss will be
includible directly on the federal income tax return of holders of Residual
Certificates ("Residual Holders") as ordinary income or loss, and will not be
taxed separately to the REMIC. The daily portions of REMIC taxable income or net
loss for a Residual Holder are determined by allocating the REMIC's taxable
income or net loss for each calendar quarter ratably to each day in such quarter
and by allocating such daily portion among the Residual Holders in proportion to
their respective holdings of Residual Certificates in the REMIC on such day.
REMIC taxable income is generally determined in the same manner as the taxable
income of an individual using the accrual method of accounting, except that (i)
the limitation on deductibility of investment interest expense and expenses for
the production of income do not apply, (ii) all bad loans will be deductible as
business bad debts, and (iii) the limitation on deductibility of interest and
expenses related to tax-exempt income will apply. The REMIC's gross income
includes interest, original issue discount income, and market discount income,
if any, on the Mortgage Loans or the mortgage loans underlying the Mortgage
Certificates owned by the REMIC, reduced by amortization of any premium on the
Mortgage Loans or the mortgage loans underlying the Mortgage Certificates, plus
amortization of premium on CitiCertificates issued at a premium, plus income on
reinvestment of cash flows and reserve assets, plus any cancellation of
indebtedness income upon allocation of realized losses to the CitiCertificates.
The REMIC's deductions include interest and original issue discount expense on
the CitiCertificates, servicing fees on the Mortgage Loans or the mortgage loans
underlying the Mortgage Certificates, other administrative expenses and realized
losses on the Mortgage Loans or Mortgage Certificates. The requirement that
Residual Holders report their pro rata share of taxable income or net loss of
the REMIC will continue until there are no Certificates of any Class of the
related Series outstanding.

     The taxable income recognized by a Residual Holder in any taxable year will
be affected by, among other factors, the relationship between the timing of
recognition of interest and original issue discount or market discount income or
amortization of premium with respect to Mortgage Loans or the mortgage loans
underlying the Mortgage Certificates, on the one hand, and the timing of
deductions for interest (including original issue discount) or income from
amortization of issue premium on the CitiCertificates, on the other hand. In the
event that an interest in the Mortgage Loans or in the mortgage loans underlying
a Mortgage Certificate is acquired by the REMIC at a discount, and one or more
of such loans is prepaid, the Residual Holder may recognize taxable income
without being entitled to receive a corresponding amount of cash because (i) the
prepayment may be used in whole or in part to make distributions in reduction of
Stated Amount of CitiCertificates, and (ii) the discount on the Mortgage Loans
or underlying mortgage loans which is includible in income may exceed the
deduction allowed upon such distributions on those CitiCertificates on account
of any unaccrued original issue discount relating to those CitiCertificates.
When there is more than one Class of CitiCertificates on which distributions in
reduction of Stated Amount are made sequentially, this mismatching of income and
deductions is particularly likely to occur in the early years following issuance
of the CitiCertificates when distributions in reduction of Stated Amount are
being made in respect of the earlier Classes of CitiCertificates to the extent
such Classes are not issued with substantial discount. If taxable income
attributable to such a mismatching is realized, in general, corresponding losses
would be allowed in later years as distributions on the later Classes of
CitiCertificates are made. Taxable income may also be greater in earlier years
than in later years as a result of the fact that interest expense deductions,
expressed as a percentage of the outstanding Stated


                                       48

<PAGE>

Amount of the CitiCertificates, may increase over time as distributions in
reduction of Stated Amount are made on the lower yielding Classes of
CitiCertificates, whereas interest income with respect to any given Mortgage
Loan or mortgage loans underlying a Mortgage Certificate will remain constant
over time as a percentage of the outstanding principal amount of that loan.
Consequently, Residual Holders must have sufficient other sources of cash to pay
any federal, state, or local income taxes due as a result of such mismatching or
unrelated deductions against which to offset such income, subject to the rules
on "excess inclusions" discussed below. The timing of such mismatching of income
and deductions described in this paragraph, if present with respect to a Series
of CitiCertificates, may have a significant adverse effect upon a Residual
Holder's after-tax rate of return. In addition, a Residual Holder's taxable
income during certain periods may exceed the income reflected by such Residual
Holder for such periods in accordance with generally accepted accounting
principles. Investors should consult their own accountants concerning the
accounting treatment of their investment in such Certificates.

  Basis and Losses

     The amount of any net loss of the REMIC that may be taken into account by
the Residual Holder is limited to the adjusted basis of the Residual Certificate
as of the close of the quarter (or time of disposition of the Residual
Certificate, if earlier), determined without taking into account the net loss
for the quarter. The initial adjusted basis of a purchaser of a Residual
Certificate is the amount paid for such Residual Certificate. Such adjusted
basis will be increased by the amount of taxable income of the REMIC reportable
by the Residual Holder and will be decreased (but not below zero), first, by a
cash distribution from the REMIC and, second, by the amount of loss of the REMIC
reportable by the Residual Holder. Any loss that is disallowed on account of
this limitation may be carried over indefinitely by the Residual Holder for whom
such loss was disallowed and may be used by such Residual Holder only to offset
any income generated by the same REMIC.

     A Residual Holder will not be permitted to amortize directly the cost of
its Residual Certificate as an offset to its share of the taxable income of the
related REMIC. However, that taxable income will not include cash received by
the REMIC that represents a recovery of the REMIC's basis in its assets. Such
recovery of basis by the REMIC will have the effect of amortization of the issue
price of the Residual Certificates over their life. However, in view of the
possible acceleration of the income of Residual Holders described above under
"--Taxation of REMIC Income", the period of time over which such issue price is
effectively amortized may be longer than the economic life of the Residual
Certificates.

     A Residual Certificate may have a negative value if the net present value
of anticipated tax liability exceeds the present value of anticipated cash
flows. The REMIC Regulations appear to treat the issue price of such a residual
interest as zero rather than such negative amount for purposes of determining
the REMIC's basis in its assets. The preamble to the REMIC Regulations states
that the Internal Revenue Service may provide future guidance on the proper tax
treatment of payments made by the transferor of such a residual interest to
induce the transferee to acquire the interest, and Residual Holders should
consult their own tax advisors in this regard.

     To the extent that the initial adjusted basis of a Residual Holder (other
than the original holder) in the Residual Certificate is greater than the
corresponding portion of the REMIC's basis in the Mortgage Loans or Mortgage
Certificates, the Residual Holder will not recover a portion of such basis until
termination of the REMIC unless otherwise provided in subsequent legislation or
future Treasury regulations. The REMIC Regulations currently in effect do not so
provide. See "Treatment of Certain Items of REMIC Income and Expense-Market
Discount" below regarding the basis of Mortgage Loans or Mortgage Certificates
to the REMIC and "Sale or Exchange of a Residual Certificate" below regarding
possible treatment of a loss upon termination of the REMIC as a capital loss.

  Treatment of Certain Items of REMIC Income and Expense

     Although the Issuer intends to compute REMIC income and expense in
accordance with the Code and applicable regulations, the authorities regarding
the determination of specific items of income and expense are subject to
differing interpretations. The Issuer makes no representation as to the specific
method that it will use for reporting income with respect to the Mortgage Loans
and expenses with respect to the CitiCertificates and different methods could
result in different timing of reporting of taxable income or net loss to
Residual Holders or differences in capital gain versus ordinary income.

     Original Issue Discount and Premium. Generally, the REMIC's deductions for
original issue discount and income or offset to interest (expense) from
amortization of issue premium will be determined in the same manner as


                                       49

<PAGE>

original issue discount income and premium amortization on CitiCertificates as
described above under "--Taxation of CitiCertificates--Original Issue Discount,"
"--Variable Rate CitiCertificates" and "--Deferred Interest" without regard to
the de minimis rule described therein, and "--Premium."

     Deferred Interest. Any Deferred Interest that accrues with respect to any
adjustable rate Mortgage Loans held by the REMIC will constitute income to the
REMIC and will be treated in a manner similar to the Deferred Interest that
accrues with respect to CitiCertificates as described above under "Taxation of
CitiCertificates--Deferred Interest".

     Market Discount. The REMIC will have market discount income in respect of
mortgage loans directly held by the REMIC or underlying a Mortgage Certificate
if, in general, the basis of the REMIC allocable to such mortgage loans is
exceeded by their unpaid principal balances. The REMIC's basis in such mortgage
loans is their fair market value immediately after their transfer to the REMIC.
The REMIC Regulations provide that such basis is equal in the aggregate to the
issue prices of all regular and residual interests in the REMIC (or the fair
market value thereof at the Closing Date in the case of a retained class). The
accrued portion of such market discount would be recognized currently as an item
of REMIC ordinary income in a manner similar to original issue discount. Market
discount income generally should accrue in the manner described above under
"--Taxation of CitiCertificates-Market Discount."

     Premium. Generally, if the basis of the REMIC in mortgage loans held
directly by the REMIC or underlying a Mortgage Certificate exceeds the unpaid
principal balances of the mortgage loans, the REMIC will be considered to have
acquired such mortgage loans at a premium equal to the amount of such excess. As
stated above, the REMIC's basis in such mortgage loans is their fair market
value immediately after their transfer to the REMIC, based on the aggregate of
the issue prices (or the fair market values of retained classes) of the regular
and residual interests in the REMIC. As described above under "Taxation of
CitiCertificates--Premium," a person who holds mortgage loans as capital assets
under Code Section 1221 may elect under Code Section 171 to amortize premium on
the mortgage loans described above that were originated after September 27, 1985
under the constant yield method. Amortizable bond premium will be treated as an
offset to interest income on the mortgage loans, rather than as a separate
deduction item. Because substantially all of the mortgagors on the mortgage
loans described above are expected to be individuals, Code Section 171 will not
be available for premium on mortgage loans originated on or prior to September
27, 1985. Premium with respect to such mortgage loans may be deductible in
accordance with a reasonable method regularly employed by the holder of such
mortgage loans. The allocation of such premium pro rata among principal payments
should be considered a reasonable method; however, the Internal Revenue Service
may argue that such premium should be allocated in a different manner, such as
allocating such premium entirely to the final payment of principal.

  Limitations on Offset or Exemption of REMIC Income

     A portion (or all) of the REMIC taxable income includible in determining
the federal income tax liability of a Residual Holder will be subject to special
treatment. That portion, referred to as the "excess inclusion," is equal to the
excess of REMIC taxable income for the calendar quarter allocable to a Residual
Certificate over the daily accruals for such quarterly period of (i) 120% of the
long term applicable Federal rate that would have applied to the Residual
Certificate (if it were a debt instrument) on the Startup Day under Code Section
1274(d), multiplied by (ii) the adjusted issue price of such Residual
Certificate at the beginning of such quarterly period. For this purpose, the
adjusted issue price of a Residual Certificate at the beginning of a quarter is
the issue price of the Residual Certificate, plus the amount of the daily
accruals of REMIC income for all prior quarters, decreased by any distributions
made with respect to such Residual Certificate prior to the beginning of such
quarterly period. Accordingly, the portion of the REMIC's taxable income that
will be treated as excess inclusions will be a larger portion of such income as
the adjusted issue price of the Residual Certificates diminishes.

     The portion of a Residual Holder's REMIC taxable income consisting of the
excess inclusions generally may not be offset by other deductions, including net
operating loss carry forwards, on such Residual Holder's return. However, net
operating loss carryovers are determined without regard to excess inclusion
income. Further, if the Residual Holder is an organization subject to the tax on
unrelated business income imposed by Code Section 511, the Residual Holder's
excess inclusions will be treated as unrelated business taxable income of such
Residual Holder for purposes of Code Section 511. In addition, REMIC taxable
income is subject to 30% withholding tax with respect to certain persons who are
not U.S. Persons (as defined below under "Tax-Related Restrictions on Transfer
of Residual Certificates-Foreign Investors"), and the portion thereof
attributable to excess inclusions is not eligible for any


                                       50

<PAGE>

reduction in the rate of withholding tax (by treaty or otherwise). See "Taxation
of Certain Foreign Investors-Residual Certificates" below. Finally, if a real
estate investment trust or regulated investment company owns a Residual
Certificate, a portion (allocated under Treasury regulations yet to be issued)
of dividends paid by the real estate investment trust or regulated investment
company could not be offset by net operating losses of its shareholders, would
constitute unrelated business taxable income for tax exempt shareholders, and
would be ineligible for reduction of withholding to certain persons who are not
U.S. Persons. The SBJPA of 1996 has eliminated the special rule permitting
Section 593 institutions ("thrift institutions") to use net operating losses and
other allowable deductions to offset their excess inclusion income from Residual
Certificates that have "significant value" within the meaning of the REMIC
Regulations, effective for taxable years beginning after December 31, 1995,
except with respect to Residual Certificates continuously held by thrift
institutions since November 1, 1995.

     In addition, the SBJPA of 1996 provides three rules for determining the
effect of excess inclusions on the alternative minimum taxable income of a
Residual Holder. First, alternative minimum taxable income for a Residual Holder
is determined without regard to the special rule, discussed above, that taxable
income cannot be less than excess inclusions. Second, a Residual Holder's
alternative minimum taxable income for a taxable year cannot be less than the
excess inclusions for the year. Third, the amount of any alternative minimum tax
net operating loss deduction must be computed without regard to any excess
inclusions. These rules are effective for taxable years beginning after December
31, 1986, unless a Residual Holder elects to have such rules apply only to
taxable years beginning after August 20, 1996.

  Tax-Related Restrictions on Transfer of Residual Certificates

     Disqualified Organizations. If any legal or beneficial interest in a
Residual Certificate is transferred to a Disqualified Organization (as defined
below), a tax would be imposed in an amount equal to the product of (i) the
present value of the total anticipated excess inclusions with respect to such
Residual Certificate for periods after the transfer and (ii) the highest
marginal federal income tax rate applicable to corporations. The REMIC
Regulations provide that the anticipated excess inclusions are based on actual
prepayment experience to the date of the transfer and projected payments based
on the Prepayment Assumption. The present value rate equals the applicable
Federal rate under Code Section 1274(d) as of the date of the transfer for a
term ending with the last calendar quarter in which excess inclusions are
expected to accrue. Such rate is applied to the anticipated excess inclusions
from the end of the remaining calendar quarters in which they arise to the date
of the transfer. Such a tax generally would be imposed on the transferor of the
Residual Certificate, except that where such transfer is through an agent
(including a broker, nominee or other middleman) for a Disqualified
Organization, the tax would instead be imposed on such agent. However, a
transferor of a Residual Certificate would in no event be liable for such tax
with respect to a transfer if the transferee furnishes to the transferor an
affidavit that the transferee is not a Disqualified Organization and, as of the
time of the transfer, the transferor does not have actual knowledge that such
affidavit is false. The tax also may be waived by the Internal Revenue Service
if the Disqualified Organization promptly disposes of the Residual Certificate
and the transferor pays income tax at the highest corporate rate on the excess
inclusions for the period the Residual Certificate is actually held by the
Disqualified Organization.

     In addition, if a "Pass-Through Entity" (as defined below) has excess
inclusion income with respect to a Residual Certificate during a taxable year
and a Disqualified Organization is the record holder of an equity interest in
such entity, then a tax will be imposed on such entity equal to the product of
(i) the amount of excess inclusions that are allocable to the interest in the
Pass-Through Entity during the period such interest is held by such Disqualified
Organization and (ii) the federal corporate income tax rate. Such tax would be
deductible from the ordinary gross income of the Pass-Through Entity for the
taxable year. The Pass-Through Entity would not be liable for such tax if it has
received an affidavit from such record holder that it is not a Disqualified
Organization or stating such holder's taxpayer identification number and, during
the period such person is the record holder of the Residual Certificate, the
Pass-Through Entity does not have actual knowledge that such affidavit is false.

     For taxable years beginning on or after January 1, 1998, if an "electing
large partnership" holds a Residual Certificate, all interests in the electing
large partnership are treated as held by Disqualified Organizations for purposes
of the tax imposed upon a Pass-Through Entity by section 860E(c) of the Code. An
exception to this tax, otherwise available to a Pass-Through Entity that is
furnished certain affidavits by record holders of interests in the entity and
that does not know such affidavits are false, is not available to an electing
large partnership.

     For these purposes, (i) "Disqualified Organization" means the United
States, any state or political subdivision thereof, any foreign government, any
international organization, any agency or instrumentality of any of the


                                       51

<PAGE>

foregoing (provided, that such term does not include an instrumentality if all
of its activities are subject to tax and a majority of its board of directors is
not selected by any such government entity), any cooperative organization
furnishing electric energy or providing telephone service to persons in rural
areas as described in Code Section 1381(a)(2)(C), and any organization (other
than a farmers' cooperative described in Code Section 521) that is exempt from
taxation under the Code unless such organization is subject to the tax on
unrelated business income imposed by Code Section 511, (ii) "Pass-Through
Entity" means any regulated investment company, real estate investment trust,
common trust fund, partnership, trust or estate and certain corporations
operating on a cooperative basis (except as may be provided in Treasury
regulations, any person holding an interest in a Pass-Through Entity as a
nominee for another will, with respect to such interest, be treated as a
Pass-Through Entity) and (iii) an "electing large partnership" is a partnership
which had 100 or more members during the preceeding taxable year, other than
certain service partnerships and commodity pools, and elects to apply the
simplified reporting provisions of the Code.

     The Pooling Agreement with respect to a Series will provide that no legal
or beneficial interest in a Residual Certificate may be transferred or
registered unless (i) the proposed transferee provides to the transferor, CMSI
and the Trustee an affidavit providing its taxpayer identification number and
stating that such transferee is the beneficial owner of the Residual Certificate
and is not a Disqualified Organization and that it is not purchasing such
Residual Certificate on behalf of a Disqualified Organization (i.e., as a
broker, nominee or middleman thereof), and (ii) the transferor provides a
statement in writing to CMSI and the Trustee that it has no actual knowledge
that such affidavit is false. Moreover, the Pooling Agreement will provide that
any attempted or purported transfer in violation of these transfer restrictions
will be null and void and will vest no rights in any purported transferee. Each
Residual Certificate with respect to a Series will bear a legend referring to
such restrictions on transfer, and each holder of a Residual Certificate will be
deemed to have agreed, as a condition of ownership thereof, to any amendments to
the related Pooling Agreement required under the Code or applicable Treasury
regulations to effectuate the foregoing restrictions. Information necessary to
compute an applicable excise tax must be furnished to the Internal Revenue
Service and to the requesting party within 60 days of the request, and CMSI or
the Trustee may charge a fee for computing and providing such information.

     Noneconomic Residual Interests. The REMIC Regulations permit the Internal
Revenue Service to disregard certain transfers of Residual Certificates, in
which case the transferor would continue to be treated as the owner of the
Residual Certificates and thus would continue to be subject to tax on its
allocable portion of the net income of the REMIC. Under the REMIC Regulations, a
transfer of a "noneconomic residual interest" (as defined below) to a Residual
Holder (other than a Residual Holder who is not a U.S. Person, as defined below
under "Foreign Investors") is disregarded for all federal income tax purposes if
a significant purpose of the transferor is to impede the assessment or
collection of tax. A residual interest in a REMIC (including a residual interest
with a positive value at issuance) is a "noneconomic residual interest" unless,
at the time of the transfer, (i) the present value of the expected future
distributions on the residual interest at least equals the product of the
present value of the anticipated excess inclusions and the highest corporate
income tax rate in effect for the year in which the transfer occurs, and (ii)
the transferor reasonably expects that the transferee will receive distributions
from the REMIC at or after the time at which taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes on each
excess inclusion. The anticipated excess inclusions and the present value rate
are determined in the same manner as set forth above under "Disqualified
Organizations." The REMIC Regulations explain that a significant purpose to
impede the assessment or collection of tax exists if the transferor, at the time
of the transfer, either knew or should have known that the transferee would be
unwilling or unable to pay taxes due on its share of the taxable income of the
REMIC. A safe harbor is provided if (i) the transferor conducted, at the time of
the transfer, a reasonable investigation of the financial condition of the
transferee and found that the transferee historically had paid its debts as they
came due and found no significant evidence to indicate that the transferee would
not continue to pay its debts as they came due in the future, and (ii) the
transferee represents to the transferor that it understands that, as the holder
of a noneconomic residual interest, the transferee may incur tax liabilities in
excess of cash flows generated by the interest and that the transferee intends
to pay taxes associated with holding the residual interest as they become due.
The Pooling Agreement with respect to each Series of Certificates will require
the transferee of a Residual Certificate to certify to the matters in the
preceding sentence as part of the affidavit described above under the heading
"Disqualified Organizations."

     Foreign Investors. The REMIC Regulations provide that the transfer of a
Residual Certificate that has "tax avoidance potential" to a "foreign person"
will be disregarded for all federal tax purposes. This rule appears intended to
apply to a transferee who is not a "U.S. Person" (as defined below), unless such
transferee's income is effectively connected with the conduct of a trade or
business within the United States. A Residual Certificate is deemed to have


                                       52

<PAGE>

tax avoidance potential unless at the time of the transfer, (i) the future value
of expected distributions equals at least 30% of the anticipated excess
inclusions after the transfer, and (ii) the transferor reasonably expects that
the transferee will receive sufficient distributions from the REMIC at or after
the time at which the excess inclusions accrue (and prior to the end of the
succeeding taxable year) for the accumulated withholding tax liability to be
paid. If the non-U.S. Person transfers the Residual Certificate back to a U.S.
Person, the transfer will be disregarded and the foreign transferor will
continue to be treated as the owner unless arrangements are made so that the
transfer does not have the effect of allowing the transferor to avoid tax on
accrued excess inclusions.

     The Pooling Agreement and, if applicable, the Prospectus Supplement
relating to a Series, may provide that a Residual Certificate may not be
purchased by or transferred to any person that is not a U.S. Person or may
describe the circumstances and restrictions pursuant to which such a transfer
may be made. The term "U.S. Person" means a citizen or resident of the United
States, a corporation, partnership or other entity created or organized in or
under the laws of the United States or any political subdivision thereof, an
estate that is subject to United States federal income tax regardless of the
source of its income or a trust, if, (a) for taxable years beginning after
December 31, 1996 (or after August 20, 1996 if the trustee has made the
applicable election), a court within the United States is able to exercise
primary supervision over the administration of such trust, and one or more
United States fiduciaries have the authority to control all substantial
decisions of such trust, or (b) for all other taxable years, such trust is
subject to United States federal income tax regardless of the source of its
income.

  Sale or Exchange of a Residual Certificate

     Upon the sale or exchange of a Residual Certificate, the Residual Holder
will recognize gain or loss equal to the excess, if any, of the amount realized
over the adjusted basis (as described above under "--Taxation of Residual
Certificates--Basis and Losses") of such Residual Holder in such Residual
Certificate at the time of the sale or exchange. In addition to reporting the
taxable income of the REMIC, a Residual Holder will have taxable income to the
extent that any cash distribution to it from the REMIC exceeds such adjusted
basis on that Distribution Date. Such income will be treated as gain from the
sale or exchange of its Residual Certificate. It is possible that the
termination of the REMIC may be treated as a sale or exchange of a Residual
Holder's Residual Certificate, in which case, if the Residual Holder has an
adjusted basis in its Residual Certificate remaining when its interest in the
REMIC terminates, and if it holds such Residual Certificate as a capital asset
under Code Section 1221, then it will recognize a capital loss at that time in
the amount of such remaining adjusted basis.

     Any gain on the sale of a Residual Certificate will be treated as ordinary
income (i) if a Residual Certificate is held as part of a "conversion
transaction" as defined in Code Section 1258(c), up to the amount of interest
that would have accrued on the Residual Holder's net investment in the
conversion transaction at 120% of the appropriate applicable Federal rate in
effect at the time the Residual Holder entered into the transaction minus any
amount previously treated as ordinary income with respect to any prior
disposition of property that was held as a part of such transaction or (ii) in
the case of a non-corporate taxpayer, to the extent such taxpayer has made an
election under Code Section 163(d)(4) to have net capital gains taxed as
investment income at ordinary income rates. In addition, gain or loss recognized
from the sale of a Residual Certificate by certain banks or thrift institutions
will be treated as ordinary income or loss pursuant to Code Section 582(c).

     The Conference Committee Report to the 1986 Act provides that, except as
provided in Treasury regulations yet to be issued, the wash sale rules of Code
Section 1091 will apply to dispositions of Residual Certificates where the
seller of the Residual Certificate, during the period beginning six months
before the sale or disposition of the residual interest and ending six months
after such sale or disposition, acquires (or enters into any other transaction
that results in the application of Code Section 1091) any residual interest in
any REMIC or any interest in a "taxable mortgage pool" (such as a non-REMIC
owner trust) that is economically comparable to a Residual Certificate.

  Mark to Market Regulations

     Prospective purchasers of the Residual Certificates should be aware that
the Internal Revenue Service has issued final regulations (the "Mark to Market
Regulations") under Code Section 475 relating to the requirement that a
securities dealer mark to market securities held for sale to customers. This
mark-to-market requirement applies to all securities of a dealer, except to the
extent that the dealer has specifically identified a security as held for
investment. The Mark to Market Regulations provide that, for purposes of this
mark-to-market requirement, a Residual Certificate is not treated as a security
and thus may not be marked to market. The Mark to Market Regulations apply to
all Residual Certificates acquired on or after January 4, 1995.


                                       53

<PAGE>

TAXES THAT MAY BE IMPOSED ON THE REMIC

  Prohibited Transactions

     Income from certain transactions by the REMIC, called prohibited
transactions, will not be part of the calculation of income or loss includible
in the federal income tax returns of Residual Holders, but rather will be taxed
directly to the REMIC at a 100% rate. Prohibited transactions generally include
(i) the disposition of qualified mortgages other than for (a) substitution
within two years of the Startup Day for a defective (including a defaulted)
obligation (or the repurchase in lieu of substitution of a defective (including
a defaulted) obligation at any time), or for any qualified mortgage within three
months of the Startup Day, (b) foreclosure, default, or reasonably foreseeable
default of a qualified mortgage, (c) bankruptcy or insolvency of the REMIC, or
(d) a qualified (complete) liquidation, (ii) the receipt of income from assets
that are not the type of mortgage loan or investments that the REMIC is
permitted to hold, (iii) the receipt of compensation for services, or (iv) the
receipt of gain from disposition of cash flow investments other than pursuant to
a qualified liquidation. Notwithstanding (i) and (iv), it is not a prohibited
transaction to sell REMIC property to prevent a default on a regular interest as
a result of a default on qualified mortgages or to facilitate a clean-up call
(generally, an optional termination made to save administrative costs when no
more than a small percentage of the CitiCertificates is outstanding). The REMIC
Regulations indicate that a substantial modification of a Mortgage Loan
generally will not be treated as a disposition if it is occasioned by a default
or reasonably foreseeable default, an assumption of the Mortgage Loan, the
waiver of a due-on-sale clause or due-on-encumbrance clause, or the conversion
of an interest rate by a mortgagor pursuant to the terms of a convertible
adjustable rate Mortgage Loan.

  Contributions to the REMIC After the Startup Day

     In general, the REMIC will be subject to tax at a 100% rate on the value of
any property contributed to the REMIC after the Startup Day. Exceptions are
provided for cash contributions to the REMIC (i) during the three months
following the Startup Day, (ii) made to a qualified reserve fund by a Residual
Holder, (iii) in the nature of a guarantee, (iv) made to facilitate a qualified
liquidation or clean-up call, and (v) as otherwise permitted in Treasury
regulations yet to be issued.

  Net Income from Foreclosure Property

     A REMIC will be subject to federal income tax at the highest corporate rate
on "net income from foreclosure property," determined by reference to the rules
applicable to real estate investment trusts. Generally, property acquired by
deed in lieu of foreclosure would be treated as "foreclosure property" for a
period not exceeding the close of the third calendar year following the year of
acquisition, with a possible extension. Net income from foreclosure property
generally means gain from the sale of foreclosure property that is inventory
property and gross income from foreclosure property other than qualifying rents
and other qualifying income for a real estate investment trust.

LIQUIDATION OF THE REMIC

     If a REMIC adopts a plan of complete liquidation within the meaning of Code
Section 860F(a)(4)(A)(i), which may be accomplished by designating in the
REMIC's final tax return a date on which such adoption is deemed to occur, and
sells all of its assets (other than cash) within the 90-day period beginning on
such date, the REMIC will not be subject to the prohibited transaction rules on
the sale of its assets, provided that the REMIC credits or distributes in
liquidation all of the sale proceeds plus its cash (other than amounts retained
to meet claims) to holders of all Certificates within the 90-day period. An
early termination of the Trust effected by a repurchase by the Issuer of all
remaining Mortgage Loans or Mortgage Certificates when the adjusted balances
thereof have declined to the percentage specified for a particular Series, and
the distribution to holders of Certificates of the proceeds of such sale and any
remaining assets of the REMIC, is contingent upon receipt of an opinion of
counsel or other evidence that such repurchase and distribution will constitute
a "qualified liquidation" within the meaning of Code Section 860F(a)(4)(A) and
will not adversely affect the REMIC status of the Trust.

ADMINISTRATIVE MATTERS

     As a REMIC, the Trust must maintain its books on a calendar year basis and
must file federal income tax returns in a manner similar to a partnership for
federal income tax purposes. The form for such returns is Form 1066, U.S.


                                       54

<PAGE>

Real Estate Mortgage Investment Conduit Income Tax Return. The Trustee with
respect to a Series will be required to sign the REMIC's annual returns.
Treasury regulations provide that, except where there is a single Residual
Holder for an entire taxable year, the REMIC will be subject to the procedural
and administrative rules of the Code applicable to partnerships, including the
determination of any adjustments to, among other things, items of REMIC income,
gain, loss, deduction, or credit by the Internal Revenue Service in a unified
administrative proceeding. As long as the Issuer remains a Residual Holder with
respect to any portion of a Class of Residual Certificates, the Issuer will be
obligated to act as "tax matters person," as defined in applicable Treasury
regulations, with respect to the related Series. If the Issuer or an affiliate
is not a Residual Holder, the Residual Holder holding the largest percentage of
the Residual Certificates will be obligated to act as tax matters person and, by
purchase of a Residual Certificate, will irrevocably designate the Issuer as its
agent to act as tax matters person and agree to execute any documents required
to effectuate the actions of the Issuer in its capacity as tax matters person.
The tax matters person with respect to a Series will be, in order of priority,
(i) the Issuer or an affiliate thereof, in its capacity as a holder of a
Residual Certificate or as the agent of the holders of the Residual
Certificates, and (ii) if the Issuer or an affiliate thereof is not a Residual
Holder and is not permitted to act as tax matters person or as agent of the
holders of Residual Certificates under applicable Treasury regulations, a
Residual Holder or such other person as may be specified pursuant to Treasury
regulations.

LIMITATIONS ON DEDUCTION OF CERTAIN EXPENSES

     An investor who is an individual, estate, or trust will be subject to
limitation with respect to certain itemized deductions described in Code Section
67, to the extent that such deductions, in the aggregate, do not exceed two
percent of the investor's adjusted gross income. In addition, Code Section 68
provides that itemized deductions otherwise allowable for a taxable year of an
individual taxpayer will be reduced by the lesser of (i) 3% of the excess, if
any, of adjusted gross income over $100,000 ($50,000 in the case of a married
individual filing a separate return) (in each case, as adjusted for post-1991
inflation), or (ii) 80% of the amount of itemized deductions otherwise allowable
for such year. In the case of a REMIC, such deductions may include Servicing
Compensation (exclusive of Additional Servicing Compensation, if any) for the
related Series, servicing fees paid to the Servicer, to the servicer of the
Mortgage Loans, or to the issuer or guarantor of the Mortgage Certificates, or
any similar expenses allocated to the REMIC with respect to a regular interest
it holds in another REMIC. Such investors who hold Certificates either directly
or indirectly through certain pass-through entities may have their pro rata
share of such expenses allocated to them as additional gross income, but may be
subject to such limitations on deductions. In addition, such expenses are not
deductible at all for purposes of computing the alternative minimum tax, and may
cause such investors to be subject to significant additional tax liability.
Temporary Treasury regulations provide that such expenses and a corresponding
additional amount of gross income generally are to be allocated entirely to
holders of the Residual Certificates in the case of a REMIC that would not
qualify as a fixed investment trust in the absence of a REMIC election. However,
such additional income and limitations on deductions will apply to the allocable
portion of such expenses to holders of CitiCertificates, as well as to holders
of Residual Certificates, where such CitiCertificates are issued in a manner
that is similar to pass-through certificates in a fixed investment trust. In
general, such allocable portion will be determined based on the ratio that a
holder's income from the CitiCertificate, determined on a daily basis, bears to
the income of all holders of CitiCertificates and Residual Certificates with
respect to a REMIC. As a result, individuals, estates, or trusts holding
CitiCertificates (either directly or indirectly through a grantor trust,
partnership, S corporation, REMIC, or certain other pass-through entities
described in the foregoing temporary Treasury regulations) may have taxable
income in excess of the interest income at the Stated Rate on such
CitiCertificates that are issued in a single class or otherwise consistently
with fixed investment trust status or in excess of the amount of cash received
for the related period on Residual Certificates. Unless indicated otherwise in
the applicable Prospectus Supplement, all such expenses will be allocable to the
Residual Certificates.

TAXATION OF CERTAIN FOREIGN INVESTORS

  CitiCertificates

     Interest, including original issue discount, distributable to holders of
CitiCertificates who are non-resident aliens, foreign corporations or other
Non-U.S. Persons (i.e., any person who is not a U.S. Person), will be considered
"portfolio interest" and, therefore, generally will not be subject to 30% United
States withholding tax provided that such Non-U.S. Person (i) is not a
"10-percent shareholder" within the meaning of Code Section 871(h)(3)(B) or a


                                       55

<PAGE>

controlled foreign corporation described in Code Section 881(c)(3)(C) and (ii)
provides the Trustee, or the person who would otherwise be required to withhold
tax from such distributions under Code Section 1441 or 1442, with an appropriate
certification, signed under penalties of perjury, identifying the beneficial
owner and stating, among other things, that the beneficial owner of the
CitiCertificate is a Non-U.S. Person. If such certification, or any other
required certification, is not provided, 30% withholding will apply unless
reduced or eliminated pursuant to an applicable tax treaty or unless the
interest is effectively connected with the conduct of a trade or business within
the United States by such Non-U.S. Person. In the latter case, such Non-U.S.
Person will be subject to United States federal income tax at regular rates.
Investors who are Non-U.S. Persons should consult their own tax advisors
regarding the specific tax consequences to them of owning a CitiCertificate.

     The Internal Revenue Service recently issued final regulations (the "New
Regulations") which would provide alternative methods of satisfying the
certification requirement described above. The New Regulations are effective
January 1, 2000, although valid withholding certificates that are held on
December 31, 1999, remain valid until the earlier of December 31, 2000 or the
due date of expiration of the certificate under the rules as currently in
effect. The New Regulations, in the case of CitiCertificates held by a foreign
partnership, that (x) the certification described above be provided by the
partners rather than by the foreign partnership and (y) the partnership provide
certain information, including a United States taxpayer identification number. A
look-through rule would apply in the case of tiered partnerships. Non-U.S.
Persons should consult their own tax advisors concerning the application of the
certification requirements in the New Regulations.

  Residual Certificates

     The Conference Committee Report to the 1986 Act indicates that amounts paid
to Residual Holders who are Non-U.S. Persons are treated as interest for
purposes of the 30% (or lower treaty rate) United States withholding tax.
Treasury regulations provide that amounts distributed to Residual Holders may
qualify as "portfolio interest," subject to the conditions described in
"CitiCertificates" above, but only to the extent that (i) the Mortgage Loans or
the mortgage loans underlying the Mortgage Certificates were issued after July
18, 1984 and (ii) the Trust or the segregated pool of assets therein (as to
which a separate REMIC election will be made), to which the Residual
Certificates relate, consists of obligations issued in "registered form" within
the meaning of Code Section 163(f)(1). Generally, Mortgage Loans will not be,
but Mortgage Certificates or CitiCertificates representing either regular
interests in another Trust or a segregated pool of assets within the Trust will
be, considered obligations issued in registered form. Furthermore, a Residual
Holder will not be entitled to any exemption from the 30% withholding tax (or
lower treaty rate) to the extent of that portion of REMIC taxable income that
constitutes an "excess inclusion." See "--Taxation of Residual
Certificates--Limitations on Offset or Exemption of REMIC Income." If the
amounts distributed to Residual Holders who are Non-U.S. Persons are effectively
connected with the conduct of a trade or business within the United States by
such Non-U.S. Persons, 30% (or lower treaty rate) withholding will not apply.
Instead, the amounts paid to such Non-U.S. Persons will be subject to United
States federal income tax at regular rates. If 30% (or lower treaty rate)
withholding is applicable, such amounts generally will be taken into account for
purposes of withholding only when paid or otherwise distributed (or when the
Residual Certificate is disposed of under rules similar to withholding upon
disposition of debt instruments that have original issue discount). See
"--Taxation of Residual Certificates--Tax-Related Restrictions on Transfer of
Residual Certificates--Foreign Investors," above concerning the disregard of
certain transfers having "tax avoidance potential." Investors who are Non-U.S.
Persons should consult their own tax advisors regarding the specific tax
consequences to them of owning a Residual Certificate.

BACKUP WITHHOLDING

     Distributions made on the CitiCertificates and proceeds from the sale of
the CitiCertificates to or through certain brokers may be subject to a "backup"
withholding tax under Code Section 3406 of 31% of "reportable payments"
(including interest distributions, original issue discount, and, under certain
circumstances, distributions in reduction of Stated Amount) unless, in general,
the holder of the CitiCertificate complies with certain reporting and/or
certification procedures, including the provision of its taxpayer identification
number to the Trustee, its agent or the broker who effected the sale of the
CitiCertificate, or such Certificateholder is otherwise an exempt recipient
under applicable provisions of the Code. Any amounts so withheld from
distributions on the CitiCertificates would be refunded by the Internal Revenue
Service or allowed as a credit against the holder's federal income tax
liability. The New Regulations change certain of the rules relating to certain
presumptions currently available relating to


                                       56

<PAGE>

information reporting and backup withholding. Non-U.S. Persons are urged to
contact their own tax advisors regarding the application to them of backup
withholding and information reporting.

REPORTING REQUIREMENTS

     Reports of accrued interest, original issue discount and information
necessary to compute the accrual of market discount will be made annually to the
Internal Revenue Service and to individuals, estates, non-exempt and
non-charitable trusts, and partnerships who are either holders of record of
CitiCertificates or beneficial owners who own CitiCertificates through a broker
or middleman as nominee. All brokers, nominees and all other non-tax-exempt
holders of record of CitiCertificates (including corporations, non-calendar year
taxpayers, securities or commodities dealers, real estate investment trusts,
investment companies, common trust funds, thrift institutions and charitable
trusts) may request such information for any calendar quarter by telephone or in
writing by contacting the person designated in Internal Revenue Service
Publication 938 with respect to a particular Series of Certificates. Holders
through nominees must request such information from the nominee.

     The Internal Revenue Service's Form 1066, U.S. Real Estate Mortgage
Investment Conduit Income Tax Return, has an accompanying Schedule Q, Quarterly
Notice to Residual Interest Holders of REMIC Taxable Income or Net Loss
Allocation. Treasury regulations require that Schedule Q be furnished by the
REMIC to each Residual Holder by the last day of the month following each
calendar quarter (41 days after the end of a quarter under proposed Treasury
regulations) in which the REMIC is in existence.

     Treasury regulations require that, in addition to the foregoing
requirements, information must be furnished quarterly to Residual Holders and,
if applicable, furnished annually to holders of CitiCertificates and filed
annually with the Internal Revenue Service concerning Code Section 67 expenses
(see "Limitations on Deduction of Certain Expenses" above) allocable to such
holders. Furthermore, under such regulations, information must be furnished
quarterly to Residual Holders, furnished annually to holders of
CitiCertificates, and filed annually with the Internal Revenue Service
concerning the percentage of the REMIC's assets meeting the qualified asset
tests described above under "Status of CitiCertificates and Residual
Certificates."

                              PLANS OF DISTRIBUTION

     Certificates are being offered hereby in Series (each Series evidencing a
separate Pool) through one or more of the methods described below. The
Prospectus Supplement prepared for each Series will describe the method of
offering being utilized for that Series and will state the public offering or
purchase price of such Series, or the method by which such price is to be
determined, and the net proceeds from such sale.

     The Issuer intends that Certificates will be offered through the following
methods from time to time and that offerings may be made concurrently through
more than one of these methods or that an offering of a particular series of
Certificates may be made through one or more of these methods:

     1.   By negotiated firm commitment underwriting and public re-offering by
          underwriters;

     2.   By placements by the Issuer with investors through dealers or agents;
          and

     3.   By secondary offerings by an affiliate thereof in any of the manners
          set forth above.

     If underwriters are used in a sale of any Certificates, such Certificates
will be acquired by the underwriters for their own account and may be resold
from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices to be
determined at the time of sale or at the time of commitment therefor. Firm
commitment underwriting and public re-offering by underwriters may be done
through underwriting syndicates led by one or more managing underwriters or
through one or more firms acting alone. The specific managing underwriter or
underwriters, if any, with respect to the offer and sale of a particular series
of Certificates will be set forth on the cover of the Prospectus Supplement
relating to such Series and the members of the underwriting syndicate, if any,
will be named in such Prospectus Supplement. The Prospectus Supplement will
describe any discounts and commissions to be allowed or paid by the Issuer to
the underwriters, any other items constituting underwriting compensation and any
discounts and commissions to be allowed or paid to the dealers or agents. The
obligations of the underwriters will be subject to certain conditions precedent.
The underwriters with respect to a sale of Certificates will be obligated to
purchase all such Certificates if any are purchased. The Issuer and


                                       57

<PAGE>

Citicorp will indemnify the several underwriters against certain civil
liabilities, including liabilities under the Securities Act.

     The Prospectus Supplement with respect to any Series of Certificates
offered other than through underwriters will contain information regarding the
nature of such offering and any agreements to be entered into between the Issuer
and dealers for the Certificates of such Series.

     Affiliates of the Issuer may act as agents or underwriters in connection
with the sale of a Series of Certificates. Any affiliate of the Issuer so acting
will be named, and its affiliation with the Issuer and Citicorp described, in
the Prospectus Supplement with respect to such Series.

     The Issuer anticipates that the Certificates will be sold primarily to
institutional investors. Purchasers of Certificates, including dealers, may,
depending on the facts and circumstances of such purchases, be deemed to be
"underwriters" within the meaning of the Securities Act in connection with
re-offers and sales by them of Certificates. Certificateholders should consult
with their legal advisors in this regard prior to any such re-offer or sale.

                 THE MORTGAGE LOANS AND CITIMORTGAGECERTIFICATES

     This Appendix describes the Mortgage Loans contained in a Pool (including a
pool underlying a CitiMortgageCertificate), certain pooling and servicing
arrangements with respect to a Pool, the insurance arrangements in respect of
such Mortgage Loans and additional material in connection therewith.

     Certain statements contained in this Appendix may be wholly or partly
inapplicable to a particular Series of Certificates. Any material divergence
from the following descriptions of the Mortgage Loans will be discussed in the
applicable Prospectus Supplement. Section references herein preceded by "PA"
refer to Pooling Agreement sections.

THE MORTGAGE LOANS

  General

     When used in this Appendix A, the term "Pool" refers to either a Pool
consisting of Mortgage Loans or a pool of Mortgage Loans underlying a
CitiMortgageCertificate. A Pool consisting in whole or in part of Mortgage Loans
originated by Citibank as well as a pool of Mortgage Loans originated by
Citibank and which underlie a CitiMortgageCertificate are each herein referred
to as a "Citibank Pool." A Pool consisting in whole or in part of Mortgage Loans
originated or acquired by CMI as well as a pool of Mortgage Loans originated or
acquired by CMI and which underlie a CitiMortgageCertificate is herein referred
to as a "CMI Pool." A Pool consisting in whole or in part of Mortgage Loans
originated or acquired by CitiMae or its affiliates is referred to herein as a
"CitiMae Pool." A Pool consisting in whole or in part of Mortgage Loans acquired
by CMSI from other affiliates as well as a pool of Mortgage Loans acquired by
CMSI from other affiliates and which underlie a CitiMortgageCertificate is
herein referred to as a "CMSI Pool." A Pool consisting in whole or in part of
Mortgage Loans originated or acquired by CFSB as well as a pool of Mortgage
Loans originated or acquired by CFSB and which underlie a
CitiMortgageCertificate is herein referred to as a "CFSB Pool." A Pool
consisting in whole or in part of Mortgage Loans originated by Third Party
Originators as well as a pool of Mortgage Loans originated by Third Party
Originators and which underlie a CitiMortgageCertificate is herein referred to
as a "Third Party Pool." Each Pool may include either fixed interest rate
Mortgage Loans (each such Pool, a "Fixed Rate Pool") or adjustable interest rate
Mortgage Loans (each such Pool, an "ARM Pool"). A portion of the interest
component of a Mortgage Loan may be retained by an Originator and not
transferred to a Pool. The information contained herein in respect of CMI Pools
applies generally to Mortgage Loans originated by other affiliates (except
CitiMae) and contained in CMSI Pools and CMI Pools. Such Mortgage Loans may
include mortgage loans originated or acquired by CFSB or originated by Citibank.
The information contained herein in respect of CitiMae Pools applies generally
to the Mortgage Loans originated by CitiMae Originators in accordance with the
terms of the CitiMae Sellers' Guide. Each Pool will include loans (the "Real
Estate Loans") evidenced by promissory notes secured by first mortgages or deeds
of trust on one- to four-family residences. A Pool may also contain, in addition
to Real Estate Loans, cooperative apartment loans (the "Cooperative Loans")
evidenced by promissory notes (the "Cooperative Notes") secured by security
interests in shares issued by private, non-profit, cooperative housing
corporations (the "Cooperatives") and in the related proprietary leases or
occupancy agreements granting exclusive rights to occupy specific dwelling units
in such cooperatives' buildings (the one- to four-family residences and the
shares issued by cooperatives are hereinafter referred to as the "Mortgaged
Properties"). Unless otherwise provided in the Prospectus Supplement, the
buildings owned by such cooperatives will be located in the New York
Metropolitan Area in the States of New York and New Jersey, the Chicago
Metropolitan Area in the State of Illinois and the Washington Metropolitan Area
in the District of Columbia and the State of Maryland. The Mortgaged Properties
may consist of (i) detached homes, (ii) attached homes (one- to four-family
units having a common wall), (iii) units located in condominiums or planned unit
developments and (iv) such other types of homes or units as are set forth in the
Prospectus Supplement. The Mortgaged Properties may include investment
properties and vacation and second homes, and may include leasehold interests.
The Mortgaged Properties will be located in states as set forth in the
Prospectus Supplement. Each Mortgage Loan will be selected by the Issuer from
among those originated or acquired by the relevant Originator in the ordinary
course of its business activities or acquired by the relevant Originator from
another Originator.

     All Mortgage Loans will (i) have individual principal balances at
origination of not more than $2,500,000,(ii) have monthly payments due on the
first day of each month, (iii) be secured by Mortgaged Properties located in one


                                      A-1

<PAGE>

of the fifty states of the United States, the District of Columbia, or the
Commonwealth of Puerto Rico, (iv) be fixed rate or adjustable rate loans which
may provide for full amortization of principal, deferral of a portion of
interest, balloon payments of principal or have such other characteristics as
set forth in the related Prospectus Supplement and (v) have original maturities
as specified in the related Prospectus Supplement. Unless otherwise specified in
the applicable Prospectus Supplement, the original principal amount of each
Mortgage Loan will not be more than 95% of the Original Value of the related
Mortgaged Property. The principal amount of the "loan," for purposes of
computation of loan-to-value ratios, includes the amount of any part of an
origination fee that is financed. The financed portion of the origination fee
will be less than 5% of the loan amount in each case.

     Unless otherwise stated in the applicable Prospectus Supplement, a Pool may
contain Real Estate Loans, the original terms of which were modified prior to
their inclusion in such Pool pursuant to modification agreements (the
"Modification Agreements") or pursuant to modification, consolidation and
extension agreements (the "Consolidation Agreements"). A Modification Agreement
generally alters only the stated annual interest rate and (as a result) the
monthly payment amount for a Mortgage Loan. The terms of a Consolidation
Agreement may alter any one or more of the following: the type of Mortgage Loan,
the identity of a borrower or borrowers, the stated annual interest rate or
manner of determining such rate, the maturity date, the monthly payment amount
or the principal amount of the obligation secured by the mortgage. The
Consolidation Agreement amends the existing mortgage and the obligation secured
thereby. If additional principal was advanced at the time of amendment, the
Consolidation Agreement consolidates the new mortgage relating to the additional
principal with the existing mortgage. With respect to Real Estate Loans, the
terms of which were modified pursuant to Modification Agreements or
Consolidation Agreements, whenever the terms "original," "originated" or
"origination" are used in this Prospectus or any Prospectus Supplement to
describe certain characteristics of the Mortgage Loans on a particular date,
generally such terms shall refer to such characteristics (a) in the case of
Modification Agreements, at the original date of the extension of credit under
such Mortgage Loan except for the stated annual interest rate and monthly
payment as stated above and (b) in the case of Consolidation Agreements, at the
date of the applicable Consolidation Agreement and as modified thereby.

     It is anticipated that each Pool will consist predominantly of Mortgage
Loans determined by the Issuer to be secured by the primary residence of the
borrower (the "Mortgagor"). The sole basis for such determination will be either
(i) the making of a representation by the Mortgagor at origination of the
Mortgage Loan either that the underlying property will be used by the Mortgagor
for a period of at least six months every year or that the Mortgagor intends to
use the underlying property as a primary residence, or (ii) a finding that the
address of the underlying Mortgaged Property is the Mortgagor's mailing address
as reflected in the Originator's records. The aggregate Adjusted Balance of
Mortgage Loans for which such determination shall have been made will be
disclosed in the applicable Prospectus Supplement or, if not known at the time a
Series is offered, set forth in a report on Form 8-K which will be filed with
the Commission and made available to the CitiCertificateholders within 15 days
of the initial issuance of a Series. In the case of Mortgage Loans which were
assumed by a new borrower after origination, the representation made or the
information given by the original Mortgagor at origination in respect of (i) and
(ii) above is used to determine such disclosure in the related Prospectus
Supplement and as set forth in a report on Form 8-K.

     The Issuer will represent that no Mortgage Loan in a Pool will be 30 days
or more past due as of the first day of the month during which the related
Series is issued or has been 30 days or more past due more than once in the
12-month period immediately preceding such day and, in the event that such Pool
consists in whole or in part of Issuer Certificates, the Issuer will make a
representation as to delinquency information available with respect to the
Mortgage Loans in which such Issuer Certificates evidence interests. For other
representations to be made by the Issuer concerning the Mortgage Loans, see
"--Assignment of Mortgage Loans." In addition, at the date of initial issuance
of any Series, the aggregate Adjusted Balance of the Mortgage Loans included in
the related Pools will not be less than $20,000,000. As used herein, references
to aggregate principal balances to be used for determining weighted averages,
percentages for termination of the Pools, or credit support amounts (but not
repurchase prices) shall mean the scheduled principal balances thereof as of the
close of business on the first day of the applicable month (whether or not any
scheduled payments have been received on subsequent days) less Principal
Prepayments thereon or in respect thereof received or posted prior to the close
of business on the business day preceding such first day (or, in the case of the
Cut-Off Date, any Principal Prepayments thereon or in respect thereof received
or posted prior to the close of business on the Cut-Off Date) (the "Adjusted
Balance").

     Property securing a Mortgage Loan may be encumbered by a subordinated
mortgage loan. Any such subordinated mortgage loan may have been originated by
an Affiliated Originator, either at the time of origination of the Mortgage Loan
or otherwise. The Prospectus Supplement will not include the amount of the
subordinated loan in the loan-to-value calculation included therein. It is the
policy of each Affiliated Originator to provide a subordinate loan in connection
with the origination of the first priority Mortgage Loan only if the combined
amount of such loans would result in a loan-to-value ratio of 90% or less.
Primary mortgage insurance is generally not required for these loans. The
proprietary lease or occupancy agreement securing a Cooperative Loan is
generally subordinate to any blanket mortgage on the related cooperative
apartment building and/or underlying land. Additionally, in the case of a
Cooperative Loan, the proprietary lease or occupancy agreement is subject to
termination and the cooperative shares are subject to cancellation by the
cooperative if the tenant-stockholder fails to pay maintenance or other
obligations or charges owed by such tenant-stockholder. See "--Certain Legal
Aspects of the Mortgage Loans--Cooperatives."

     Mortgage Loans originated by Affiliated Originators and having original
principal amounts exceeding 90% of Original Value will be covered, and Mortgage
Loans having original principal balances exceeding 80% but not more than 90% of
Original Value may be covered, by primary mortgage insurance against default
until the outstanding principal amount is reduced to at least 80% of Original
Value through principal payments made by the Mortgagor or, in the case of CFSB
Pools containing Mortgage Loans originated or acquired by the California and
Florida branches of CFSB, until the outstanding principal amount thereof is less
than or equal to 80% of either the Original Value through principal payments
made by the Mortgagor or the value thereof as determined by a new appraisal
delivered subsequent to origination. So long as it is in effect, such primary
mortgage insurance will cover losses arising from a default up to an amount
ranging from 12% to 30% of the principal amount of the Mortgage Loan outstanding
from time to time. Prior to 1986, the Affiliated Originators did not generally
make one- to four-family real estate loans with loan-to-value ratios above 80%
unless such Originator had obtained primary mortgage insurance coverage. From
1986 through January 1993, each Affiliated Originator originated mortgage loans
with loan-to-value ratios in excess of 80% but not more than 90% without
obtaining primary mortgage insurance. Since February 1993, it has been the
policy of each Affiliated Originator not to make one- to four-family real estate
loans with loan-to-value ratios above 80% without obtaining primary mortgage
insurance. The policy of CitiMae Originators is to require primary mortgage
insurance for one- to four-family real estate loans with current loan-to-value
ratios in excess of 80%.

     Each Prospectus Supplement will include, among other things, information,
as of the date of such Prospectus Supplement and to the extent then known to the
Issuer, as to (i) the aggregate Adjusted Balance of the Mortgage Loans to be
delivered into the related Pool and the years of origination thereof, (ii) if
Converted Mortgage Loans with an aggregate Adjusted Balance exceeding 10% of the
aggregate Adjusted Balance of all Mortgage Loans in the related Pool are to be
delivered, the aggregate Adjusted Balance of any such Converted Mortgage Loans,
(iii) the original loan-to-value ratios of the Mortgage Loans (which will not
include the amount of any subordinated loan in such loan-to-value calculation),
(iv) the types of Mortgaged Properties securing the Mortgage Loans, (v) the
geographic distribution of the Mortgaged Properties, prepared on a
state-by-state basis for states where Mortgage Loans having an aggregate
Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of Mortgage
Loans in the related Pool are located, (vi) if Buydown Mortgage Loans with an
aggregate Adjusted Balance exceeding 10% of the aggregate Adjusted Balance of
all Mortgage Loans in the related Pool are to be delivered, the aggregate
Adjusted Balance of Buydown Mortgage Loans in the related Pool, (vii) if
Leasehold Loans with an aggregate Adjusted Balance exceeding 10% of the
aggregate Adjusted Balance of all Mortgage Loans in the related Pool are to be
delivered, the aggregate Adjusted Balance of Leasehold Loans in the related Pool
and (viii) if 15-year, fixed rate tiered-payment Mortgage Loans originated by
CFSB's California branches and providing for a prepayment penalty during the
first 12 months following origination with an aggregate Adjusted Balance
exceeding 10% of the aggregate Adjusted Balance of all Mortgage Loans in the
related Pool are to be delivered, the aggregate Adjusted Balance of such
Mortgage Loans in the related Pool. In the event specific information with
respect to the Pool is not known at the time a Series is offered, more general
information of the nature described above will be provided in such Prospectus
Supplement and the specific information described above will be set forth in a
report on Form 8-K which will be filed with the Commission and made available to
Certificateholders of the Series within 15 days of the initial issuance of such
Series.

     The Issuer will be responsible for administering and servicing the Mortgage
Loans purchased, directly or indirectly, by the Trust from CMI, Citibank or CFSB
or their affiliates (the "Affiliated Originators") and will act as master
servicer with respect to Mortgage Loans purchased, directly or indirectly, by
the Trust (a) from CitiMae or its affiliates who purchased mortgage loans from
seller-servicers approved by CitiMae or from such seller-servicers


                                      A-3

<PAGE>

("CitiMae Originators") or (b) from Third Party Originators, and will perform
such functions as are described in the Pooling Agreement. The Issuer may
delegate any of its duties under the Pooling Agreement to any corporation,
including a corporation more than 50% of the stock of which is owned, directly
or indirectly, by Citicorp. Unless otherwise disclosed in the related Prospectus
Supplement, if the Mortgage Loans are included directly in the Pool, the Issuer
will subcontract its duties as servicer of the Affiliated Mortgage Loans to CMI
(or its designated subservicer) and its duties as master servicer (a) with
respect to the CitiMae Mortgage Loans to CitiMae and (b) with respect to the
Third Party Loans sold by Third Party Originators on a servicing-retained basis,
to the then-current servicers of such Third Party Loans (which will be qualified
to so service the Third Party Loans in accordance with CMI's servicing
guidelines). CitiMae will subcontract such duties to various third party
servicers qualified to do so in accordance with CitiMae's servicing guidelines.
Such delegation does not relieve the Issuer of its responsibility with respect
to such duties (the Issuer and CMI in such capacity, the "Servicer" and CitiMae
and such servicers of Third Party Loans, in such capacity, "Subservicer" or
"Master Servicer"). The Servicer may at any time delegate or subcontract or
assign any of its duties as servicer under any Pooling Agreement to any
corporation, including a corporation more than 50% of the stock of which is
owned, directly or indirectly, by Citicorp. In the event of any such delegation
or subcontract, the Servicer will remain responsible for the delegee's or
subcontractor's performance in accordance with the Pooling Agreement. A
servicing fee will be paid to the Servicer with respect to each payment of
interest received with respect to each Mortgage Loan. Such servicing fee paid to
the Servicer may be in an amount equal to a fixed annual percentage as specified
in the related Prospectus Supplement for all Mortgage Loans in such Pool of the
outstanding principal balance of such Mortgage Loan on which interest is
payable. In such event, the remainder of such interest, constituting interest at
the mortgage rate for such Mortgage Loan (the "Note Rate") less such rate of
servicing compensation (the "Pass-Through Rate" for such Mortgage Loan), is
available for distributions of interest at the Stated Rate and distributions of
principal to holders of the related CitiMortgageCertificates, CitiCertificates
and Residual Certificates, as applicable, and to pay any REMIC Servicing Fee or
fee to the issuer of credit support. Alternatively, if so specified in the
related Prospectus Supplement, the Pass-Through Rate may be the same (or
calculated in the same manner) for each Mortgage Loan in the Pool, and the rate
of servicing compensation with respect to each Mortgage Loan (equal to the
difference between the Note Rate for such Mortgage Loan and such Pass-Through
Rate) may differ among different Mortgage Loans or in the case of the CitiMae
Mortgage Loans, the fee may be equal to an expense rate equal to a master
servicing fee (the "Master Servicing Fee"), a servicing fee paid to various
third party servicers (the "Servicing Fee") and a fee for other related
expenses. The Servicer will be entitled to retain all late payment charges,
assumption fees and similar charges, and all income or gain on funds held in the
related Certificate Account referred to below, as additional servicing
compensation. The Servicer will pay all expenses incurred in connection with the
servicing of the Mortgage Loans, including the fees of any subcontractor. See
"--Servicing and Other Compensation and Payment of Expenses" below.

     There can be no assurance that the foreclosure and delinquency experience
on the Mortgage Loans underlying the CitiCertificates or the Certificates will
be comparable to that set forth under "Delinquency, Foreclosure and Loss
Considerations and Experience." If the residential real estate market should
experience an overall decline in property values such that the outstanding
balances of the Mortgage Loans and any secondary financing on the Mortgaged
Properties or interests in cooperatives in a particular Pool become equal to or
greater than the value of the Mortgaged Properties or interests in cooperatives
subject to the Mortgage Loans included in such Pool, the actual rates of
delinquencies, foreclosures and losses could be significantly higher than those
now generally experienced in the mortgage lending industry. To the extent that
such delinquencies, foreclosures and losses are not covered by obligations under
any form of credit support, they will be borne by the holders of the related
CitiCertificates.

     Because the principal amounts of Mortgage Loans (other than ARMs which
provide for a portion of interest to be deferred and added to the principal
balance of such ARMs) will decline monthly as principal payments, including
prepayments, are received, the principal balance of each CitiMortgageCertificate
in a series will decline correspondingly. The Stated Amount of each
CitiCertificate will decline as described under "Description of Certificates" in
the body of this Prospectus or in the related Prospectus Supplement.

  Fixed Rate Pools

     A Fixed Rate Pool may contain any one or more of the following types of
fixed interest rate Mortgage Loans:

     (i) fully amortizing Mortgage Loans providing for level monthly payments of
principal and interest;

     (ii) growing equity Mortgage Loans providing for initial monthly payments
based on a 10 to 30 year amortization schedule, with further provisions for
scheduled annual payment increases at rates, unless otherwise


                                      A-4

<PAGE>

specified in the applicable Prospectus Supplement, of not less than 3% or more
than 8.25% of the scheduled monthly payments during the preceding year, with the
full amount of such increases being applied to principal;

     (iii) tiered payment Mortgage Loans initially providing only for full
payment of interest and payment of little or no principal for up to three years,
with further provisions for annual Mortgagor payment increases, beginning in the
second year, unless otherwise specified in the applicable Prospectus Supplement,
of up to 7.5% of the monthly Mortgagor payments during the preceding year and
continuing annually until monthly Mortgagor payments are adequate to amortize
fully such Mortgage Loans over the remainder of the original terms;

     (iv) Mortgage Loans amortizing over a fixed number of years but which have
a shorter term to maturity that causes the outstanding principal balance of the
Mortgage Loan to be due and payable at the end of a certain specified period;

     (v) fully amortizing graduated-payment Mortgage Loans ("GPMs"), other than
those described above, which provide for lower periodic payments, or for
payments of interest only, during the early years of the term, followed by
periodic payments of principal and interest that increase periodically at a
predetermined rate until the Mortgage Loan is repaid or for a specified number
of years, after which level periodic payments begin; or

     (vi) other fixed rate Mortgage Loans having the characteristics set forth
in the related Prospectus Supplement.

     A Fixed Rate Pool may contain one or more Mortgage Loans each of which was
originated as an adjustable interest rate Mortgage Loan but has been converted,
at the sole option of the Mortgagor, into a fixed interest rate, fully
amortizing Mortgage Loan providing for level monthly payments over a term not
exceeding its remaining term to maturity (a "Converted Mortgage Loan"). Except
as otherwise provided in this Prospectus and in the applicable Prospectus
Supplement, a Converted Mortgage Loan at origination is subject to the same
origination and underwriting guidelines as a comparable adjustable rate mortgage
and such a Converted Mortgage Loan is not underwritten again at the time of its
conversion. The Note Rate (and, accordingly, the scheduled monthly payments) on
such a Converted Mortgage Loan may be higher or lower than the mortgage note
rate at the time of origination of such Converted Mortgage Loan. No Fixed Rate
Pool will contain Mortgage Loans which provide for negative amortization.

  ARM Pools

     ARM Pools will include only adjustable interest rate Mortgage Loans
("ARMs"), each bearing interest at a Note Rate which adjusts periodically to a
rate equal to the applicable Index plus the number of basis points specified in
the Pooling Agreement or in the related mortgage note (the "Mortgage Margin" for
such ARM), subject to any periodic rate ceiling ("Periodic Ceiling") and
periodic rate floor ("Periodic Floor") and any lifetime maximum note rate
("Maximum Note Rate") or a Maximum Note Rate and a lifetime minimum note rate
("Minimum Note Rate"), if applicable, as described below. Each adjusted Note
Rate is generally rounded to the nearest 0.125%, subject to the applicability of
a Minimum Note Rate and a Maximum Note Rate. A Periodic Ceiling limits the
amount of any single periodic increase in the Note Rate and a Periodic Floor
limits the amount of any single periodic decrease in the Note Rate. A Maximum
Note Rate limits the amount of increases in the Note Rate over the life of an
ARM and a Minimum Note Rate limits the amount of decreases in the Note Rate over
the life of an ARM. Except with respect to ARMs with Minimum Note Rates, there
is no minimum Note Rate to which the Note Rate in an ARM may adjust. The Note
Rates of the ARMs in a given ARM Pool will adjust as described in the applicable
Prospectus Supplement and an ARM Pool may contain ARMs with different adjustment
dates. Certain ARMs may provide for periodic adjustments of scheduled monthly
payments in order to amortize fully the Mortgage Loan by its stated maturity
while other ARMs may permit that maturity to be extended or shortened in
accordance with the portion of each payment that is applied to interest in
accordance with the periodic Note Rate adjustments.

     Where an ARM provides for limitations on the amount by which monthly
payments may be increased or changes to the Note Rate of the ARM are made more
frequently than payment changes, it is possible that an increase in the Note
Rate will not be covered by the amount of the scheduled monthly payment. In that
case, the uncollected portion of interest will be deferred and added to the
principal balance of the ARM.

     The amount of the difference between the scheduled monthly payment and the
monthly interest accrued at the Mortgage Rate is added to the unpaid principal
balance of the Mortgage Loan and interest accrues on such added principal at the
then-applicable Mortgage Rate from the date of such addition. Such an adjustment
is referred to as "negative amortization". Negative amortization tends to
lengthen the weighted average life of the Mortgage Loans


                                      A-5

<PAGE>

and may cause payments near the maturity of the Mortgage Loan to be larger than
the previously scheduled monthly payments unless the terms of the Mortgage Loan
permit its maturity to be extended. If a Pool includes Mortgage Loans that
provide for negative amortization, the related Supplement will describe certain
of the effects on holders of Certificates as of the preceding Record Date of
such Series.

     Prior to the first adjustment of the Note Rate on an ARM, the scheduled
monthly payment by the Mortgagor is the amount which will fully amortize the
principal balance of the ARM in equal installments over its remaining term and
pay interest at the initial Note Rate. In the case of ARMs which provide for
periodic adjustments of scheduled monthly payments, on the first day of the
month following the month in which a Note Rate adjusts, the Mortgagor is
required to begin making scheduled monthly payments in amounts which will fully
amortize the principal balance of the ARM in equal installments over its
remaining term and pay interest at the adjusted Note Rate except in the case of
certain ARMs which provide for a deferral of a portion of interest, as described
in the preceding paragraph. The Mortgagor under an ARM may have been qualified
at an interest rate which is lower than the current interest rate at
origination. Accordingly, the repayment of such ARM is dependent on the ability
of the Mortgagor to make larger monthly payments after the initial Note Rate
adjustment date.

     The applicable Prospectus Supplement will contain information respecting
the index (the "Index") utilized to adjust the Note Rates of ARMs, the Mortgage
Margin, the frequency of interest rate and payment adjustments, the Periodic
Ceiling, the Periodic Floor, the Maximum Note Rate, the Minimum Note Rate, if
applicable, and provisions for deferred interest, if any. The ARMs included in a
particular ARM Pool will be more fully described in the related Prospectus
Supplement.

YIELD CONSIDERATIONS

     A description of yield considerations with respect to any Series of
CitiCertificates, to the extent such considerations differ from those described
below, will be set forth in the related Prospectus Supplement.

     The yield on any CitiCertificate or CitiMortgageCertificate will depend on
the price paid, the effective interest rate of the CitiCertificate or
CitiMortgageCertificate and the prepayment experience with respect to the
Mortgage Loans underlying the related Series.

  Price

     Subject to the effect of the amount of interest payable in connection with
prepayments as described below, prepayments of principal on the Mortgage Loans
in a Pool will increase the yield on a related CitiCertificate or
CitiMortgageCertificate purchased at a price less than the aggregate Adjusted
Balance of the Mortgage Loans in a Pool represented by such CitiCertificate or
CitiMortgageCertificate and will decrease the yield on a related CitiCertificate
or CitiMortgageCertificate purchased at a price greater than the aggregate
Adjusted Balance of the Mortgage Loans represented by such CitiCertificate or
CitiMortgageCertificate.

  Effective Interest Rate

     Interest on each Mortgage Loan is payable in arrears. Each monthly interest
payment on a Mortgage Loan is calculated as 1/12 of the applicable Note Rate
multiplied by the unpaid principal balance of such Mortgage Loan outstanding as
of the first day of the month. The amount of such payments distributed monthly
with respect to each Mortgage Loan will be similarly calculated on the basis of
the Pass-Through Rate for such Mortgage Loan. The difference between the Note
Rate and the Pass-Through Rate for a Mortgage Loan will be retained by the
servicer as servicing compensation. See "--Servicing and Other Compensation and
Payment of Expenses" below. If so indicated in the related Prospectus
Supplement, a portion of the Note Rate may be retained by the applicable
Originator or the Subservicer.

     The yield on a CitiCertificate or CitiMortgageCertificate will be slightly
lower than the yield otherwise produced by the applicable fixed Stated Rate
because, while interest will accrue on each Mortgage Loan from the first day of
each month, the distribution of such interest at the applicable fixed Stated
Rate will not be made until the applicable Distribution Date in the month
following the end of the related period during which interest has accrued. Full
or partial prepayments received and posted during any calendar month are passed
through to holders of CitiCertificates or CitiMortgageCertificates on the
applicable Distribution Date immediately following such calendar month. In the
case of the Affiliated Mortgage Loans, interest on such a full or partial
prepayment will be paid


                                      A-6

<PAGE>

at the Stated Rate for such entire calendar month (regardless of when during
such month such prepayment is received) to the extent of Servicing Compensation
(exclusive of any amount designated as "additional servicing compensation" in
the related Prospectus Supplement, and subject to any limit described in the
related Prospectus Supplement) for such calendar month. In the case of the
CitiMae Mortgage Loans, such an interest will be paid to the extent of the
Master Servicing Fee. Therefore, to the extent such Servicing Compensation or
the Master Servicing Fee, as applicable, equals or exceeds any shortfall in
collections of interest on account of full or partial prepayments, principal
prepayments will not affect the yield to holders of CitiCertificates or
CitiMortgageCertificates, except as provided in the preceding sentence and under
the heading "Price" above. Payment of interest on prepayments on Third Party
Loans will be made as described in the related Prospectus Supplement.

     To the extent the loan servicing and collection practices of any
subcontractor or the timing and accruals of interest on principal prepayments
vary from those disclosed in this paragraph, the applicable Prospectus
Supplement will describe such differences.

  Other Yield Considerations

     The Note Rates on ARMs adjust periodically in response to movements in the
Index. In connection with ARM Pools which provide for periodic adjustments to
scheduled monthly payments, the first distribution on the related
CitiCertificates or CitiMortgageCertificates reflecting a periodic adjustment to
scheduled monthly payments on the underlying ARMs will be passed through to
holders on the Distribution Date in the month following the month in which the
Note Rate on an ARM is adjusted. Furthermore, unless otherwise described in the
related Prospectus Supplement, adjustments in the Note Rates are based on the
relevant Index most recently available as of the date 45 days prior to the date
of the Note Rate adjustment. Accordingly, the yield to certificateholders of ARM
pools will be adjusted on a delayed basis relative to movements in the Index.
Furthermore, adjustments to the Note Rate on an ARM may be limited by a Minimum
Note Rate, Maximum Note Rate, Periodic Floor and Periodic Ceiling. The following
table illustrates the timing of the adjustments and receipt by
Certificateholders of related distributions for a hypothetical ARM Pool
containing ARMs having an adjustment date of July 1. All dates are assumed to be
business days.

May 1 ...................   Index is published.

July 1 ..................   Note Rates are adjusted based on the May 15 Index.

August 1 ................   Mortgagors make the first adjusted monthly payments
                            at the adjusted Note Rates.

August 18 ...............   Determination Date.

August 25 ...............   First payment to Certificateholders including
                            interest at the adjusted Pass-Through Rate which
                            payment reflects the adjusted scheduled monthly
                            payments on the underlying ARMs.

PREPAYMENT EXPERIENCE

     The Mortgage Loans may be prepaid in full or in part at any time. The
prepayment experience of the Mortgage Loans will affect the weighted average
life of a series of CitiCertificates or CitiMortgageCertificates. Based on the
Originators' experience with their own conventional fixed interest rate mortgage
loan portfolios and public information with respect to the mortgage lending
industry, the Issuer anticipates that a significant number of Mortgage Loans
will be paid in full prior to their scheduled maturities. A number of factors,
including homeowner mobility, economic conditions, enforceability of due-on-sale
clauses, any prepayment penalty contained in the Mortgage Loans, mortgage market
interest rates and the availability of mortgage funds, may influence
prepayments. In general, due-on-sale clauses for Mortgage Loans will be enforced
in a manner consistent with applicable law whenever such due-on-sale clauses are
contained in the mortgage documents and such enforcement would not violate the
contractual arrangements with the Mortgagors. See "--Certain Legal Aspects of
the Mortgage Loans --Enforceability of Certain Provisions, Prepayment Charges
and Prepayments" below.

     Unless the Prospectus Supplement indicates otherwise, Mortgage Loans
representing at least 90% of the aggregate Adjusted Balance of the Mortgage
Loans in a Fixed Rate Pool will contain a due-on-sale clause permitting the
mortgagee to accelerate the maturity of the Mortgage Loan upon conveyance by the
Mortgagor of the Mortgaged Property. Generally, ARMs in an ARM Pool will contain
a due-on-sale clause permitting the mortgagee to accelerate only in situations
where its security may be impaired.

     Servicing institutions for loan pools are sometimes asked to refinance
existing loans by accepting prepayments of loans and making new loans secured by
the same property or assigning existing loans to new lenders, or by otherwise
modifying the terms of existing mortgage loans. A mortgagor may be legally
entitled to require a lender to grant such an assignment of a real estate loan.
See "--Certain Legal Aspects of the Mortgage Loans--Enforceability of Certain
Provisions, Prepayment Charges and Prepayments" below. The Issuer reserves the
right to offer incentives such as favorable loan terms or reduced fees to
encourage borrowers to refinance existing Mortgage Loans. The Issuer also
reserves the right to offer to mortgagors, at the request of mortgagors,
modifications of the terms of existing Mortgage Loans as an alternative to
refinancing, consistent with the REMIC provisions of the Code and the terms of
the applicable Pooling Agreement. Upon any such modification, the Issuer will
repurchase such Mortgage Loan from the Pool. The Issuer reserves the right to
accept prepayments of Mortgage Loans in any Pool and to make new loans to the
same borrowers or to refinance Real Estate Loans in any Pool pursuant to a
Consolidation Agreement. Upon any such refinancing or modification, either
pursuant to a Consolidation Agreement or a Modification Agreement or through the
extension of a new loan to the borrower, the refinanced or modified Mortgage
Loan will be treated as fully prepaid and removed from the Pool. The principal
balance of any such refinanced or modified Mortgage Loan together with interest
accrued thereon at the applicable Pass-Through Rate through the last day of the
month in which such refinancing or modification occurred will be distributed to
CitiCertificateholders or holders of the CitiMortgageCertificate, as the case
may be, in the month following the refinancing or modification.

     The Servicer permits Mortgagors to participate in certain "prepayment
programs" with unaffiliated service agencies. Under those programs, generally a
Mortgagor makes 26 bi-weekly payments during a calendar year, each payment being
in the amount of one-half of the Mortgagor's scheduled monthly principal and
interest payment, resulting in 13 monthly payments being made per year. Twelve
of these monthly payments are applied as such on each applicable Due Date. All
of the thirteenth payment is applied as a curtailment in reduction of the
outstanding principal balance of the Mortgage Loan, thus effecting a more rapid
repayment of the Mortgage Loan and reducing the aggregate amount of accrued
interest payable on such Mortgage Loan.

     See also "The Pooling Agreements--Termination; Repurchase of Mortgage Loans
and Mortgage Certificates" in the body of this Prospectus for a description of
the option to repurchase the Mortgage Loans or Mortgage Certificates in any Pool
when the aggregate principal balance thereof is less than the percentage
(generally 5%) specified in the applicable Prospectus Supplement of the
aggregate Adjusted Balance thereof as of the Cut-Off Date for the related
Series.

ASSIGNMENT OF MORTGAGE LOANS

     At the time of issuance of each Series of Certificates, the affiliate of
the Issuer originating or acquiring the Mortgage Loans in a Pool, other than a
Pool which consists wholly of Issuer Certificates, will assign the Mortgage
Loans to the Trustee, together with all principal and interest received on or
with respect to such Mortgage Loans (if


                                      A-8

<PAGE>

specified in the applicable Prospectus Supplement, a portion of the interest
received on a Mortgage Loan may be retained by an Originator or a Subservicer)
after the first day of the month of issuance of such Certificates (the "Cut-Off
Date") other than principal and interest due and payable on or before the
Cut-Off Date. Mortgage Loans underlying Issuer Certificates will have been so
assigned to the Underlying Trustee at the time of issuance of such Issuer
Certificates. The Trustee or its agent will, concurrently with such assignment,
authenticate and deliver the Certificates evidencing such Series. Each Mortgage
Loan will be identified in a schedule appearing as an exhibit to the Pooling
Agreement. Such schedule will include information as to the Adjusted Balance of
each Mortgage Loan as of the close of business on the Cut-Off Date, as well as
information with respect to the Note Rate, the scheduled monthly payment of
principal and interest, the maturity date or term and, if such Pool contains
Cooperative Loans, the number of Mortgage Loans which are Cooperative Loans. (PA
Section 2.01)

     In addition, the Issuer or the affiliate of the Issuer originating or
acquiring the Real Estate Loans in a Pool, other than a Pool which consists
wholly of Issuer Certificates, will, as to each Real Estate Loan in such Pool,
deliver to the Trustee (or to the custodian hereinafter referred to) the
Mortgage Note endorsed either manually or by facsimile signature, any
assumption, modification, buydown or conversion to fixed interest rate
agreement, any certificate of primary mortgage insurance, a mortgage assignment
in recordable form (except as provided below) and the original recorded Mortgage
or, in the case of Cooperative Loans, the related Cooperative Note, the original
security agreement, the proprietary lease or occupancy agreement, the
recognition agreement, an executed financing statement (if required at
origination under applicable law) and the relevant stock certificate and related
blank stock powers; provided that, in instances where recorded documents cannot
be delivered due to delays in connection with recording, the originator may
deliver copies thereof and deliver the original recorded documents promptly upon
receipt. In addition, in lieu of delivering a mortgage assignment in recordable
form, the originator may instead deliver a blanket assignment which will not be
in recordable form, together with a power of attorney appointing the Trustee its
attorney-in-fact to act for and on behalf of such originator in preparing,
executing, delivering and recording in the name of the Trustee any and all
instruments of assignment with respect to the Mortgages. Real Estate Loans that
underlie Issuer Certificates will have been so delivered to the Underlying
Trustee at the time of issuance of such Issuer Certificates.

     The Originators and the Issuer do not expect to record or file any
assignments of the Mortgage Loans to the Trustee subsequent to the issuance of
CitiMortgageCertificates or CitiCertificates, as the case may be. Such
recordation or filing is not necessary to make the assignment of the Mortgage
Loans to the related Trustee effective between such Trustee and the applicable
Originator or the Issuer. However, so long as the Trustee is not the mortgagee
of record, the Trustee might not be able, acting directly in its own name, to
enforce the Mortgage against the related Mortgaged Property or Mortgagor and may
be required to act indirectly through the mortgagee of record (who shall be an
Originator or an affiliate of an Originator). In addition, if any of the
Originators or the Issuer were to make a sale, assignment, satisfaction or
discharge of any Mortgage Loans prior to recording or filing the assignment to
such Trustee, the other parties to such sales, assignments, satisfactions or
discharges might have rights superior to those of such Trustee. If any of the
Originators or the Issuer were to do so without authority under the Pooling
Agreement, it would be liable to the Pool or the holders of the related
CitiCertificates or CitiMortgageCertificates. Moreover, if insolvency or
receivership proceedings, as the case may be, relating to any of the Originators
or the Issuer were commenced prior to such recording or filing, creditors of
such Originator or the Issuer, as the case may be, may be able to assert rights
in the affected Mortgage Loans superior to those of such Trustee.

     The Trustee will review the above-mentioned documents (including any
Mortgage Certificates) within 90 days of the delivery of such documents and
shall promptly notify the Issuer if any document is not delivered or is found to
be defective in any material respect. If the Issuer cannot deliver such document
or cure such defect within 180 days (90 days if the defect affects the status of
the Mortgage Loan as a "qualified mortgage" for REMIC purposes) after notice
thereof, the Issuer will repurchase the related Mortgage Loan (or Mortgage
Certificate) from the Trustee within 180 days (90 days if the defect affects the
status of the Mortgage Loan as a "qualified mortgage" for REMIC purposes) after
such notice at a price equal to the principal balance owed by the Mortgagor,
plus accrued and unpaid interest thereon at the applicable Pass-Through Rate to
the first day of the month following the month of repurchase, less any
unreimbursed payments under any related Guaranty or other credit support and
unreimbursed Voluntary Advances (as described below). Such repurchase will not
diminish the amount available under any related Guaranty or other credit support
and is deemed to be a reimbursement. Except as provided in the last sentence of
this paragraph, this repurchase obligation constitutes the sole remedy available
to the CitiCertificateholders or the Trustee against the Issuer for a material
defect in a document relating to a Mortgage Loan. The Issuer will have certain
rights to substitute


                                      A-9

<PAGE>

Mortgage Loans or Mortgage Certificates in respect of a Pool. See "The
Pools--Substitution of Mortgage Loans" in the body of this Prospectus. In
respect of a Pool, the related Originator will be required to cure any defect in
a document relating to, or repurchase, any Mortgage Loan which it originated or
acquired and which is found defective or repurchased by the Issuer.

     In the Pooling Agreement the Issuer will represent and warrant to the
related Trustee, among other things, that (i) the information set forth in the
schedule of Mortgage Loans attached thereto is correct in all material respects,
(ii) a lender's title and insurance policy or binder (or other satisfactory
evidence of title) for each Real Estate Loan was issued on the date of
origination thereof and each such policy or binder is valid and remains in full
force and effect, (iii) at the date of initial issuance of the CitiCertificates,
it has good title to the Mortgage Loans or the Mortgage Certificates and such
Mortgage Loans or Mortgage Certificates are free of offsets, defenses or
counterclaims and, in the case of Mortgage Certificates, free of liens, security
interests and other encumbrances, (iv) at the date of initial issuance of the
CitiCertificates, each Mortgage subject to such Pooling Agreement is a valid
first lien on the property securing the related Mortgage Note (subject only to
(a) the lien of current real property taxes and assessments, (b) covenants,
conditions and restrictions, rights of way, easements and other matters of
public record as of the date of the recording of such Mortgage, such exceptions
appearing of record being acceptable to mortgage lending institutions generally
or specifically reflected in the related appraisal and (c) other matters to
which like properties are commonly subject which do not materially interfere
with the benefits of the security intended to be provided by the Mortgage) and
such property is free of material damage and is in good repair, (v) if the Pool
includes Cooperative Loans, at the date of the initial issuance of the
CitiCertificates, each security interest created by the cooperative security
agreement is a valid first lien (subject only to the right of the related
cooperative to cancel the shares and terminate the proprietary lease for unpaid
assessments representing the Mortgagor's pro rata share of the cooperative's
payments for its blanket mortgage, current and future real property taxes,
maintenance charges and other capital and ordinary expenses to which like
collateral is commonly subject and for unpaid special assessments owed by the
Mortgagor to the cooperative) on the collateral securing the related Cooperative
Note, and the dwelling unit to which the Cooperative Loan relates is free of
material damage and is in good repair (it being recognized by the parties to the
Pooling Agreement that, while the Issuer warrants that each such security
interest is a valid first lien on the collateral securing the related
Cooperative Note, subject to the exceptions noted, the related proprietary lease
and occupancy agreement may be subordinated or otherwise subject to the lien of
any mortgage on the related cooperative building), (vi) at the applicable
Cut-Off Date, no subject Mortgage Loan is 30 days or more past due or has been
30 days or more past due more than once in the 12-month period immediately
preceding the Cut-Off Date and there are no delinquent tax or assessment liens
against the property covered by the related Mortgage, (vii) at the date of
initial issuance of the CitiCertificates, the portion of each Mortgage Loan, if
any, which in the circumstances set forth under "General" above and in the
applicable Prospectus Supplement should be insured by a private mortgage insurer
is so insured and (viii) each Mortgage Loan at the time it was made complied in
all material respects with applicable state and federal laws, including, without
limitation, usury, equal credit opportunity and disclosure laws. In addition,
the Issuer will warrant in respect of a Mortgage Loan in a Pool that (a) at the
date of the initial issuance of the CitiCertificates, there is no mechanics'
lien or claim for work, labor or material affecting the premises which is or may
be prior to or equal with the lien of such Mortgage (except those insured by the
related title insurance policy), (b) the original principal amount of each
Mortgage Loan was not more than 95% of the Original Value of such Mortgage Loan
and (c) the Mortgage Loans and Mortgage Certificates conform in all material
respects with the descriptions thereof in this Prospectus and the Prospectus
Supplement. Within 180 days of the discovery by the Issuer of a breach of any
representation or warranty which materially and adversely affects the interests
of the CitiCertificateholders, or its receipt of notice thereof from the Trustee
(or within 90 days of discovery by the Issuer of a failure to conform to the
representations and warranties in the Pooling Agreement that affects the status
of a Mortgage Loan as a "qualified mortgage" for REMIC purposes), the Issuer
will cure the breach or repurchase the Mortgage Loan (or Mortgage Certificate)
or substitute a Mortgage Loan or Mortgage Certificate on the terms set forth in
the preceding paragraph. Such repurchase will not diminish the amount available
under any related Guaranty or other form of credit support. In addition, the
Issuer will indemnify the Pool for any losses to such Pool not reimbursed by
such repurchase. Such repurchase obligation and limited indemnity constitute the
sole remedies available to the CitiCertificateholders or the Trustee for any
such breach. (PA Section 2.03) If Standard & Poor's Ratings Group ("S&P")
initially assigns a rating to the CitiCertificates, then at any time that S&P's
rating of Citicorp's long-term senior debt is below the rating S&P has assigned
to the highest rated outstanding Class (or Subclass) of a particular Series of
CitiCertificates, each related


                                      A-10

<PAGE>

Trustee will be required either to maintain possession of the related Mortgage
Notes or to appoint a custodian (which could be itself), which may not be an
affiliate of the Issuer, to maintain possession of the related Mortgage Notes.

     The Trustee will maintain possession of the documents relating to the
Mortgage Loans; provided, however, the Trustee will be authorized to appoint a
custodian or custodians, which may be an affiliate of the Issuer, except in the
circumstances described in the preceding paragraph, to maintain possession of
the documents relating to the Mortgage Loans. Such custodian may maintain all or
part of the documents relating to the Mortgage Loans. Any custodian will keep
such documents as the Trustee's agent under a custodial agreement.

PAYMENTS ON MORTGAGE LOANS IN POOLS

     The Pooling Agreements will provide that the Issuer will establish and
maintain with one or more depository banks, savings and loan associations or
trust companies, any of which may be an affiliate of the Issuer (each, a
"Depository"), one or more accounts (the "Certificate Account") in the name of
the Trustee for the benefit of CitiCertificateholders. Amounts with respect to
any Series may, at the option of the Issuer, be held in the same deposit account
as amounts with respect to any other Series, provided that the rating by each
nationally recognized statistical rating organization of each such Series is the
same. For payments made on the Affiliated Mortgage Loans, the initial Depository
will be Citibank (New York State), unless otherwise specified in the applicable
Prospectus Supplement. For the Certificate Account related to the Affiliated
Mortgage Loans, upon two weeks' prior written notice to the Trustee, CMSI may at
any time and from time to time in its discretion transfer or direct the Trustee
in writing to transfer the Certificate Account relating to the Affiliated
Mortgage Loans to any Depository which meets any of the requirements as stated
below. In the event that the long-term debt obligations of any Depository of the
Certificate Account relating to the Affiliated Mortgage Loans shall be rated at
less than A2 by Moody's Investors Service, Inc. ("Moody's"), or the short-term
debt obligations of such depository shall be rated by S&P at less than A-1 or by
Moody's at less than P-1, then within five Business Days of such reduction, CMSI
shall (A) transfer or direct the Trustee in writing to transfer the Certificate
Account relating to the Affiliated Mortgage Loans to a Depository the long-term
debt obligations of which are not rated by Moody's at less than A2 and the
short-term debt obligations of which are not rated at less than A-1 by S&P and
P-1 by Moody's (the "Rating Requirements"), (B) establish another account in the
corporate trust department of the Trustee or, if such Trustee has a long-term
and short-term debt rating at least equal to the Rating Requirements, in any
department of the Trustee (the "Alternative Certificate Account") and direct the
Servicer to remit on a daily basis any funds deposited into the Certificate
Account relating to the Affiliated Mortgage Loans to the Alternative Certificate
Account, (C) (i) cause such Depository to pledge securities in the manner
provided by applicable law or (ii) pledge or cause to be pledged securities,
which shall be held by the Trustee or its agent free and clear of the lien of
any third party, in a manner conferring on the Trustee a perfected first lien
and otherwise reasonably satisfactory to the Trustee; such pledge in either case
to secure such Depository's performance of its obligations in respect of the
Certificate Account relating to the Affiliated Mortgage Loans to the extent, if
any, that such obligation is not fully insured by the FDIC; provided, however,
that prior to the day the Depository or CMSI, as the case may be, pledges the
securities, CMSI and the Trustee shall have received the written assurance of
each rating agency which assigned a rating to the CitiCertificates that the
pledging of such securities and any arrangements or agreements relating thereto
will not result in a reduction or withdrawal of the then-current rating of the
CitiCertificates, (D) establish an account or accounts or enter into an
agreement so that the existing Certificate Account relating to the Affiliated
Mortgage Loans is supported by a letter of credit or some other form of credit
support, which issuer of such letter of credit or other form of credit support
has a long-term and short-term debt rating at least equal to the Rating
Requirements; provided, however, that prior to the establishment of such an
account or the entering into of such an agreement, CMSI and the Trustee shall
have received written assurance from each rating agency which assigned a rating
to the CitiCertificates that the establishment of such an account or the
entering into of such an agreement so that the existing Certificate Account
relating to the Affiliated Mortgage Loans is supported by a letter of credit or
some other form of credit support will not result in a reduction or withdrawal
of the then-current rating on the CitiCertificates or (E) make such other
arrangements as to which CMSI and the Trustee have received prior written
assurance from each rating agency which assigned a rating to the
CitiCertificates that such arrangement will not result in a reduction or
withdrawal of the then-current rating on the CitiCertificates. In the event that
the rating on the CitiCertificates has been downgraded as a result of a rating
downgrade of the Depository, for purposes of this paragraph, the then-current
rating on the CitiCertificates shall be the rating assigned to the
CitiCertificates immediately prior to any such downgrade.


                                      A-11

<PAGE>

     For the Certificate Account relating to the CitiMae Mortgage Loans and the
Third Party Loans, CMSI will establish and maintain accounts which are either
(i) maintained with a depositary institution the obligations of which (or in the
case of a depository institution that is the principal subsidiary of a holding
company, the obligations of such holding company) are rated in one of the two
highest rating categories by each rating agency that rated one or more classes
of the related Series of Certificates, (ii) an account or accounts the deposits
in which are fully insured by the FDIC, (iii) an account or accounts the
deposits in which are insured by the FDIC to the limits established by the FDIC
and the uninsured deposits in which are otherwise secured such that, as
evidenced by an opinion of counsel, the Certificateholders have a claim with
respect to the funds in such account or accounts, or a perfected first-priority
security interest against any collateral securing such funds, that is superior
to the claims of any other depositors or general creditors of the depository
institution with which such account or accounts are maintained or (iv) an
account or accounts otherwise acceptable to each such rating agency. The
collateral eligible to secure amounts in the Certificate Account is limited to
Eligible Investments consisting of United States government securities and other
high-quality investments.

     Payments, or proceeds of payments, of the types listed below are to be
deposited in the related Certificate Account for the related Series (other than
payments in respect of principal and interest on the related Mortgage Loans due
on or before the applicable Cut-Off Date):

          (i) all scheduled payments of principal ("Scheduled Principal") and
     Principal Prepayments (defined to mean any payment or other recovery of
     principal on a Mortgage Loan which is received in advance of its scheduled
     due date and is not accompanied by any interest scheduled for payment in
     any month subsequent to the month of prepayment) on such Mortgage Loans;

          (ii) all payments on account of interest (including payments made from
     a buydown subsidy account established with respect to such Mortgage Loans)
     on such Mortgage Loans, adjusted to the Pass-Through Rates for such
     Mortgage Loans;

          (iii) all payments under any credit support (unless such payments are
     made directly to a different account to be used for distributions to
     CitiCertificateholders by the paying agent for the CitiCertificates);

          (iv) all voluntary advances made as described below ("Voluntary
     Advances") or other payments made by the Servicer in respect of Liquidating
     Loans;

          (v) all amounts received, by foreclosure or otherwise, in connection
     with the liquidation of defaulted Mortgage Loans which have not been
     assigned to the issuer of credit support in consideration of payments under
     any such credit support, net of expenses incurred in connection with such
     liquidation;

          (vi) all proceeds received under any title, hazard or other insurance
     policy covering any Mortgage Loan (including any deductible paid by the
     Issuer in lieu thereof as permitted by the Pooling Agreement), other than
     proceeds to be applied to the restoration or repair of the related
     property, or released to the Mortgagor in accordance with normal servicing
     procedures;

          (vii) all proceeds of any repurchase by the Issuer of Mortgage Loans
     as described under "ASSIGNMENT OF MORTGAGE LOANS" or under "THE POOLING
     AGREEMENTS--Termination; Repurchase of Mortgage Loans and Mortgage
     Certificates" in the body of this Prospectus (PA Section 3.10); and

          (viii) in connection with any Principal Prepayment, the amount
     required to be deposited by the Issuer as a reduction of servicing
     compensation pursuant to the Pooling Agreement, being the difference
     between 30 days of interest at the Pass-Through Rate on the amount of such
     Principal Prepayment and the amount of interest (adjusted to the
     Pass-Through Rate) actually due thereon for the month in which such
     Principal Prepayment was posted.

     Voluntary Advances, payments by the servicer in respect of Liquidating
Loans and payments under any related Guaranty or other form of credit support
will be deposited in the Certificate Account not later than on the relevant
Distribution Date. All other amounts will be deposited in the Certificate
Account by the second business day next following the day of receipt and
posting.

     Distributions on CitiCertificates will be made as provided in the body of
this Prospectus and in the Prospectus Supplement. See "DESCRIPTION OF
CERTIFICATES." In addition, the Trustee (or such other paying agent as may be
specified in the applicable Prospectus Supplement) will, to the extent of the
obligations under credit support, include


                                      A-12

<PAGE>

with any distributions to holders (i) an amount sufficient to cover
delinquencies in scheduled payments of principal and interest, first from a
Certificate Account Advance, second from a Voluntary Advance and third, if
necessary, from payments under the credit support, (ii) if so specified in the
related Prospectus Supplement, an amount sufficient to repurchase Liquidating
Loans (either as a result of a demand or draw under the credit support or as a
result of a payment by the Servicer) and (iii) certain amounts in respect of
Principal Prepayments to the extent not paid by the Issuer, all as described in
the Prospectus Supplement. (PA Section 3.03)

     Provision is made for Voluntary Advances, Certificate Account Advances and
other payments in respect of Liquidating Loans on behalf of the issuer of credit
support in order to avoid drawings on the credit support for relatively
insignificant amounts. In the event the amount of delinquencies on Affiliated
Mortgage Loans, CitiMae Mortgage Loans or Third Party Loans cannot be covered by
an advance out of cash in the Certificate Account collected in relation to an
Affiliated Mortgage Loan, CitiMae Mortgage Loan or Third Party Loans,
respectively, being held for future distribution or withdrawal (a "Certificate
Account Advance") the Issuer may, but is not obligated to, make Voluntary
Advances to the extent that payments under credit support would otherwise be
required. The Issuer intends to make Voluntary Advances to the extent that, were
it not to do so, the issuer of the credit support would be liable for payments
under such credit support. Any such advances will be reimbursable to the extent
and in the manner payments under credit support would be reimbursed, all as
described in the Prospectus Supplement.

     Not later than three business days before each Distribution Date, the
Issuer will furnish or cause to be furnished a separate statement to the Trustee
(and to any paying agent) (the information in such statement to be made
available to the Trustee at other times by the Issuer on request) setting forth,
among other things, the aggregate amount to be distributed on such Distribution
Date on account of principal and interest, stated separately, the sources of
such amount and information relating to the amount available under the credit
support. (PA Section 3.19)

     The following chart sets forth an example of the application of the
foregoing provisions to a hypothetical CitiCertificate which represents an
interest in a Pool consisting primarily of Mortgage Loans which is issued during
January. The example would be applicable to any such CitiCertificate issued
during any other month or any CitiMortgageCertificate. (All dates referred to
are assumed to be business days).

January 1 ................    Cut-Off Date. The initial principal balance of the
                              Pool would be the aggregate Adjusted Balance of
                              the Mortgage Loans on January 1 after deducting
                              principal payments due on or before such date.
                              Principal payments due on January 1 and the
                              accompanying interest payments, which represent
                              interest on December 1 balances, are not part of
                              the Pool and will be retained by the Servicer.

January 1-January 31 .....    Payment Period. Principal Prepayments posted
                              during this period will, together with interest,
                              if any, collected thereon (adjusted to the
                              Pass-Through Rate), be deposited in the
                              Certificate Account and will be passed through to
                              CitiCertificateholders on February 25. The
                              Servicer collects interest on the prepaid amount
                              to the date of prepayment and, for partial
                              prepayments, collects no interest on the prepaid
                              amount for the month of prepayment except, that in
                              the case of certain CitiMae Mortgage Loans a full
                              month's interest will be collected. Scheduled
                              payments due on February 1 from Mortgagors will be
                              deposited in the Certificate Account as received.
                              Such payments will include the scheduled principal
                              payments received, plus interest on such Mortgage
                              Loans calculated on the January 1 principal
                              balances thereof (after deducting from such
                              balances all partial prepayments of principal
                              applied as of January 1).

January 31 ...............    Record Date. Distributions on February 25 will be
                              made to CitiCertificateholders of record at the
                              close of business on the last business day of the
                              month immediately preceding the month of
                              distribution.

February 18 ..............    Determination Date. On the 18th day of the month,
                              the Servicer determines the aggregate amount of
                              funds which are available to make distributions on
                              February 25, as described herein, determining
                              separately the aggregate amount available in the
                              Certificate Account and the amount


                                      A-13

<PAGE>

                              available as Voluntary Advances or as payments
                              under credit support to make such distributions.

February 22 ..............    Notice Date. By this date, if CMI is not the
                              paying agent for such CitiCertificates, notice of
                              the amounts to be distributed on February 25 is
                              given to the Trustee (and, if a person other than
                              the Trustee is the paying agent, to such paying
                              agent). Such notice will indicate whether the
                              obligations of any issuer of credit support are
                              sufficient to cover all delinquencies. If they
                              are, the distribution on February 25 will include
                              an amount equal to the principal and interest
                              (adjusted to the Pass-Through Rates for the
                              related Mortgage Loans) due on the Mortgage Loans
                              on February 1. If not, the distribution will
                              include only those payments due on February 1
                              which have been actually received and posted
                              before February 18. In addition, in either case,
                              Principal Prepayments posted in January will be
                              included in the February 25 distribution together
                              with interest thereon for the entire month of
                              January, adjusted to the Pass-Through Rate. The
                              Servicer will deposit in the Certificate Account
                              on February 24 the difference between such
                              interest on such Principal Prepayments for such
                              entire month and the amount of interest (adjusted
                              to the Pass-Through Rate) paid by the Mortgagors
                              on such Principal Prepayments; provided, however,
                              that the amount of such deposit shall not exceed
                              (i) Servicing Compensation (exclusive of any
                              amount designated as "additional servicing
                              compensation" in the related Prospectus
                              Supplement, and subject to any limit described
                              therein) with regard to the Affiliated Mortgage
                              Loans and (ii) the Master Servicing Fee with
                              regard to the CitiMae Mortgage Loans.

February 25 ..............    Distribution Date. On February 25, the Trustee (or
                              such other paying agent as may be specified in the
                              related Prospectus Supplement) will distribute the
                              amounts set forth in the notice to it on February
                              22 as available for distribution. If CMI is the
                              paying agent, the Servicer will furnish or cause
                              such notice to be furnished to the Trustee on or
                              before the Distribution Date. If a payment due
                              February 1 is received from a Mortgagor and posted
                              on or after February 18 and a Certificate Account
                              Advance has been made with respect to such
                              payment, such payment will be deposited into the
                              Certificate Account as reimbursement therefor. If
                              a Voluntary Advance or a payment under credit
                              support has been made with respect to such payment
                              from a Mortgagor, the Servicer will withdraw the
                              amount of such payment from the Certificate
                              Account to reimburse the entity making the
                              Voluntary Advance or the issuer of any credit
                              support. If no such advance or payment has been
                              made, such late payment will be passed through to
                              the CitiCertificateholder at the time of the next
                              distribution.

     Succeeding months follow the above, except with respect to the Cut-Off
Date.

COLLECTION AND OTHER SERVICING PROCEDURES 

  Affiliated Mortgage Loans

     The Issuer or the Servicer will make reasonable efforts to collect all
payments called for under the Affiliated Mortgage Loans and shall, consistent
with the Pooling Agreement, follow such collection procedures as it deems
necessary or advisable. Consistent with the above, the Issuer or the Servicer
may, in its discretion, (i) waive any late payment charge or any prepayment or
other charge in connection with the prepayment of an Affiliated Mortgage Loan
and (ii) arrange with a Mortgagor a schedule for the liquidation of
delinquencies running for no more than 180 days after the applicable Due Date.
Such arrangement will be made only upon determining that the coverage of such
Mortgage Loan by any Primary Mortgage Insurance Policy will not be affected. In
the event of any such arrangement, but only to the extent of an issuer's
obligations under credit support, such issuer of credit support will honor
requests for payment or otherwise distribute funds with respect to such an
Affiliated Mortgage Loan during the scheduled


                                      A-14

<PAGE>

period in accordance with the amortization schedule thereof and without regard
to the temporary modification thereof.

     If property subject to a Mortgage has been or is about to be conveyed by
the Mortgagor and the related Mortgage Loan includes a due-on-sale clause, the
Issuer or the Servicer is generally obligated to accelerate the maturity of the
Mortgage Loan. If it reasonably believes it is unable to enforce such
due-on-sale clause, the Issuer or the Servicer will enter into an assumption and
modification agreement with the person to whom such property has been or is
about to be conveyed, upon receipt of assurance that the Primary Mortgage
Insurance Policy covering such Mortgage Loan will not be affected, pursuant to
which such person becomes liable under the Mortgage Note or the Cooperative Note
and (except with respect to CFSB Pools) the original Mortgagor, to the extent
permitted by applicable law, remains liable thereon. The mortgage rate borne by
the related fixed rate Mortgage Note or Cooperative Note may not be decreased
and the mortgage rate borne by the related adjustable rate Mortgage Note or
Cooperative Note may not be changed in connection with any such assumption. The
method for determining any increase in the mortgage rate will be provided for in
the related fixed rate Mortgage Note or Cooperative Note. Any fee collected by
the Issuer or the Servicer for entering into any such assumption agreement will
be retained by the Issuer or the Servicer, as additional servicing compensation.
With regard to circumstances in which the Issuer or the Servicer may be unable
to enforce due-on-sale clauses, see "--Certain Legal Aspects of the Mortgage
Loans--Enforceability of Certain Provisions, Prepayment Charges and
Prepayments."

     In addition to a Certificate Account, the Issuer or the Servicer will
maintain with a depository, expected to be Citibank (New York State), in the
name of its Trustee, a servicing account (a "Servicing Account") with respect to
each related Series (which account may include funds with respect to other
similar mortgage pass-through certificates) and will deposit and retain therein
all payments of taxes, assessments or comparable items received for the account
of the Mortgagors relating to Affiliated Mortgage Loans. Withdrawals from any
Servicing Account may be made only to effect payment of taxes, assessments or
comparable items, to reimburse such party out of related collections for any
cost incurred in paying taxes and assessments or otherwise preserving or
protecting the value of the Mortgages, to refund to Mortgagors any amounts
determined to be overages, to pay interest to Mortgagors on balances in such
Servicing Account to the extent required by law and to clear and terminate such
Servicing Account at the termination of the related Pooling Agreement. (PA
Section 3.11)

     The Issuer or the Servicer will exercise its best reasonable efforts to
maintain and keep in full force and effect such primary mortgage insurance as
specified under "General" above and in the related Prospectus Supplement for so
long as such insurance is required pursuant to the Pooling Agreement as
specified in such section and in such Prospectus Supplement. Primary mortgage
insurance may be replaced by substantially equivalent insurance but only if (i)
each nationally recognized statistical rating organization that initially rated
the Series advises the Issuer that such replacement will not adversely affect
the current rating of such Series or (ii) the claims-paying ability of the
substitute primary mortgage insurance company is rated in the same, an
equivalent or a higher category or categories as such Series by each such
nationally recognized statistical rating organization.

  CitiMae Mortgage Loans

     Pursuant to the Pooling Agreement, the Servicer will be responsible for
servicing and administering the CitiMae Mortgage Loans. The Servicer intends to
perform such servicing and administrative functions principally through CitiMae,
Inc., as Subservicer, which will act for and on behalf of the Servicer. See "THE
ORIGINATORS--CitiMae, Inc." in the body of the Prospectus. The Subservicer has
entered or will enter into contracts with approved servicers to perform, as
independent contractors, certain servicing functions for the Servicer. One or
more servicers which are affiliates of the Servicer may perform similar
functions under other contracts with respect to the CitiMae Mortgage Loans
originated by affiliates of CitiMae. The Servicer will at all times remain
responsible for the performance of its duties under the Pooling Agreement.

     The Servicer will agree to perform diligently all services and duties
customary to the servicing by prudent mortgage lending institutions of mortgages
of the same type as the Mortgage Loans in those jurisdictions where the related
Mortgaged Properties are located. The duties to be performed by a servicer
include collection and remittance of principal and interest payments,
administration of mortgage escrow accounts, collection of insurance claims and,
if necessary, foreclosure. The Servicer will monitor each servicer's performance
and will have the right to remove a servicer of any CitiMae Mortgage Loan at any
time for cause. In the event of any such termination, the Servicer would
continue to be responsible for servicing such CitiMae Mortgage Loans and would
designate a substitute servicer


                                      A-15

<PAGE>

(which may include an affiliate of the Subservicer). During the period necessary
to effect the transfer of the servicing functions to any such substitute
servicer, or to the Servicer in the event the Servicer shall perform such
servicing functions itself, the servicer who has been terminated shall continue
to perform all of its duties and responsibilities with respect to the CitiMae
Mortgage Loans serviced by it until such time as the Servicer notifies it of
such transfer. The Servicer shall be entitled to retain the same servicing fee
as was paid to the servicer in the event the Servicer shall elect to perform
such servicing functions itself.

     The Servicer or the Subservicer will agree to proceed diligently to collect
all payments called for under the Mortgage Notes. Consistent with the above, the
Servicer or the Subservicer may, in its discretion, (i) waive any prepayment
charge, assumption fee, late payment charge or any other charge in connection
with the prepayment of a CitiMae Mortgage Loan and (ii) arrange with a Mortgagor
a plan of relief, other than a modification or extension of the Mortgage, when
appropriate rather than recommending liquidation. Such arrangement will be made
only upon determining that the coverage of such CitiMae Mortgage Loan by any
Primary Mortgage Insurance Policy will not be affected. In the event of any such
arrangement, but only to the extent of the amount of any credit support, the
provider of such credit support will honor requests for payment or otherwise
distribute funds with respect to such CitiMae Mortgage Loan during the scheduled
period in accordances with the amortization schedule thereof and without regard
to the temporary modification thereof. In addition, in the event of any such
arrangement, the Servicer's obligation to make Voluntary Advances on the related
CitiMae Mortgage Loan shall continue during the scheduled period to the extent
such Voluntary Advances are not made by the subservicer.

     Under the Pooling Agreement, the Servicer will be required to enforce
"due-on-sale" clauses with respect to the CitiMae Mortgage Loans to the extent
contemplated by the terms of the CitiMae Mortgage Loans and permitted by
applicable law. Where an assumption of, or substitution of liability with
respect to, a CitiMae Mortgage Loan is required by law, upon receipt of
assurance that the Primary Mortgage Insurance Policy covering such CitiMae
Mortgage Loan will not be affected, the Master Servicer may permit the
assumption of a CitiMae Mortgage Loan, pursuant to which the Mortgagor would
remain liable on the Mortgage Note, or a substitution of liability with respect
to such Mortgage Loan, pursuant to which the new Mortgagor would be substituted
for the original Mortgagor as being liable on the Mortgage Note. Any fees
collected for entering into an assumption or substitution of liability agreement
may be retained by the Servicer as additional servicing compensation. In
connection with any assumption or substitution, the Mortgage Rate borne by the
related Mortgage Note may not be changed.

     The Pooling Agreement may require the Servicer to establish and maintain
one or more escrow accounts into which Mortgagors deposit amounts sufficient to
pay taxes, assessments, hazard insurance premiums or comparable items.
Withdrawals from the escrow accounts maintained for Mortgagors may be made to
effect timely payments of taxes, assessments and hazard insurance premiums or
comparable items, to reimburse the Servicer out of related assessments for
maintaining hazard insurance, to refund to Mortgagors amounts determined to be
overages, to remit to Mortgagors, if required, interest earned, if any, on
balances in any of the escrow accounts, to repair or otherwise protect the
Mortgaged Property and to clear and terminate any of the escrow accounts. The
Servicer will be solely responsible for administration of the escrow accounts
and will be expected to make advances to such account when a deficiency exists
therein.

     The Issuer or the Servicer and any successor servicer appointed following
an Event of Default, will be required to maintain certain insurance covering
errors and omissions in the performance of its obligations as servicer and
certain fidelity bond coverage ensuring against losses through wrongdoing of its
officers, employees and agents. (PA Section 6.07)

  Third Party Loans

     Pursuant to the Pooling Agreement, the Servicer will be responsible for
servicing and administering the Third Party Loans. The Servicer intends to
perform such servicing and administrative functions principally through Third
Party Originators, as subservicers, with respect to Third Party Loans acquired
on a servicing-retained basis. See "THE ORIGINATORS--Third Party Originators"
herein. The Subservicer will act for and on behalf of the Servicer. The Servicer
will at all times remain responsible for the performance of its duties under the
Pooling Agreement.

HAZARD INSURANCE

     The Issuer or the Servicer will cause a hazard insurance policy to be
maintained for each Real Estate Loan. The coverage of each such policy is
required to be in an amount not less than the lesser of (x) the maximum
insurable value


                                      A-16

<PAGE>

(as established by the property insurer) of the improvements securing such Real
Estate Loan if such amount is less than the unpaid principal balance of the Real
Estate Loan, and (y) (i) the principal balance owing on such Real Estate Loan
(if such amount is greater than or equal to 80% but is less than or equal to
100% of the insurable value) or (ii) 80% of the insurable value (if the
principal balance on the Real Estate Loan is less than 80% of the insurable
value). As set forth above, all amounts collected by the Servicer under any
hazard policy (except for amounts to be applied to the restoration or repair of
property subject to the related Mortgage or property acquired by foreclosure or
amounts released to the Mortgagor in accordance with normal servicing
procedures) will be deposited in the applicable Certificate Account. In the
event that the Servicer maintains a blanket policy insuring against hazard
losses on all of the Mortgage Loans, it shall conclusively be deemed to have
satisfied its obligation relating to the maintenance of hazard insurance. Such
blanket policy may contain a deductible clause, in which case the Servicer will
deposit in the Certificate Account all sums which would have been deposited
therein but for such clause. The Servicer is required to maintain a fidelity
bond and errors and omissions policy or their equivalent with respect to
officers and employees which provide coverage against losses which may be
sustained as a result of an officer's or employee's misappropriation of funds or
errors and omissions in failing to maintain insurance, subject to certain
limitations as to amount of coverage, deductible amounts, conditions, exclusions
and exceptions in the form and amount specified in the Pooling Agreement.

     In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements on the property by fire,
lightning, explosion, smoke, windstorm and hail, riot, strike and civil
commotion, subject to the conditions and exclusions particularized in each
policy. The policies relating to such Real Estate Loans will be underwritten by
different insurers and therefore will not contain identical terms and
conditions. Such policies typically do not cover any physical damage resulting
from the following: war, revolution, governmental actions, floods and other
water-related causes, earth movement (including earthquakes, landslides and mud
flows), nuclear reactions, wet or dry rot, vermin, rodents, insects or domestic
animals, theft and, in certain cases, vandalism. The foregoing list is merely
indicative of certain kinds of uninsured risks and is not intended to be
all-inclusive. Where the property securing such a Real Estate Loan is located in
a federally designated special flood hazard zone, the applicable Pooling
Agreement will require that flood insurance be maintained.

     Most of the properties securing the Real Estate Loans will be covered by
homeowners' insurance policies which, in addition to the standard form of fire
and extended coverage, provide coverage for certain other risks. These
homeowners' policies typically contain a "coinsurance" clause which in effect
requires the insured at all times to carry insurance of a specified percentage
(generally 80% to 90%) of the full replacement value of the improvements on the
property in order to recover the full amount of any partial loss. If the
insured's coverage falls below this specified percentage, then the insurer's
liability in the event of a partial loss shall not exceed the lesser of (i) the
actual cash value (generally defined as replacement cost at the time and place
of loss, less physical depreciation) of the improvements damaged or destroyed or
(ii) such proportion of the loss as the amount of insurance carried bears to the
specified percentage of the full replacement cost of such improvements.

     Since the amount of hazard insurance required to be maintained on the
improvements securing such Real Estate Loans may decline, and since residential
properties generally have historically appreciated in value over time, the
effect of coinsurance in the event of partial loss may be that hazard insurance
proceeds will be insufficient to restore fully the damaged property. However, to
the extent of the amount available to cover hazard losses under any Guaranty or
other credit support, CitiCertificateholders will not suffer loss by reason of
delinquencies or foreclosures following hazard losses, whether or not subject to
coinsurance clauses.

     The Issuer and the Servicer will not require that a hazard or flood
insurance policy be maintained for any Cooperative Loan. Generally, the
cooperative itself is responsible for maintenance of hazard insurance for the
property owned by the cooperative, and the tenant-stockholders of that
cooperative do not maintain individual hazard insurance policies. To the extent,
however, a cooperative and the related borrower on a Cooperative Note do not
maintain such insurance or do not maintain adequate coverage or any insurance
proceeds are not applied to the restoration of the damaged property, damage to
such borrower's cooperative apartment or such cooperative's building could
significantly reduce the value of the collateral securing such Cooperative Note.

     If an issuer's obligations under credit support are exhausted, and if a
Mortgagor defaults on his obligations to make payments on a Mortgage Loan, the
CitiCertificateholders will bear all risk of loss resulting from hazard losses
not covered by hazard insurance.

PRIMARY MORTGAGE INSURANCE

     A Mortgage Loan secured by a Mortgaged Property having a loan-to-value
ratio in excess of 80% may or, in the case of a CitiMae Mortgage Loan, will have
a policy (a "Primary Mortgage Insurance Policy") insuring against default all or
a specified portion of the principal amount thereof in excess of such percentage
of the value of the Mortgaged Property, as specified in the related Prospectus
Supplement.

     Evidence of each Primary Mortgage Insurance Policy will be provided to the
Trustee simultaneously with the transfer to the Trustee of the related Mortgage
Loan. The Servicer, on behalf of itself, the Trustee and the Certificateholders,
is required to present claims to the insurer under any Primary Mortgage
Insurance Policy and to take such reasonable steps as are necessary to permit
recovery thereunder with respect to defaulted Mortgage Loans. Amounts collected
by the Servicer on such claims shall be deposited in the Certificate Account for
distribution as set forth above. The Servicer will not cancel or refuse to renew
any Primary Mortgage Insurance Policy required to be kept in force by the
Pooling Agreement. (PA Section 3.10)

MAINTENANCE OF INSURANCE POLICIES; CLAIMS THEREUNDER AND OTHER REALIZATION
UPON DEFAULTED MORTGAGE LOANS

     The Servicer will exercise its best reasonable efforts to keep each Primary
Mortgage Insurance Policy (if any) in full force and effect at least until the
outstanding principal balance of the related Mortgage Note is equal to the
percentage of the appraised value of the Mortgaged Property specified herein.
The Servicer has agreed (or will agree) to pay the premium for each Primary
Mortgage Insurance Policy on a timely basis in the event that the Mortgagor does
not make such payments.

     The Servicer, on behalf of the Trustee and Certificateholders, will present
claims to the insurer under any applicable Primary Mortgage Insurance Policy and
will take such reasonable steps as are necessary to permit recovery under such
insurance policies respecting defaulted Mortgage Loans. As set forth above, all
collections by the Servicer under such policies that are not applied to the
restoration of the related Mortgage Property are to be deposited in the
Certificate Account, subject to withdrawals as heretofore described.

     If any property securing a defaulted Mortgage Loan is damaged and proceeds,
if any, from the related hazard insurance policy are insufficient to restore the
damaged property to a condition sufficient to permit recovery under any
applicable Primary Mortgage Insurance Policy, the Servicer will not be required
to expend its own funds to restore the damaged property unless the Servicer
determines (i) that such restoration will increase the net proceeds to
Certificateholders upon liquidation of the Mortgage Loan after reimbursement of
the Servicer for its expenses and (ii) that such expenses will be recoverable to
it through liquidation proceeds.

     Regardless of whether recovery under any Primary Mortgage Insurance Policy
is available or any further amount is payable under the credit support for a
Series of Certificates, the Servicer is nevertheless obligated to follow such
normal practices and procedures as it deems necessary or advisable to realize
upon the defaulted Mortgage Loan. However, the Servicer is not required under
the Pooling Agreement to expend its own funds to foreclose on a defaulted
Mortgage Loan unless it generally determines that foreclosure would increase the
net proceeds of liquidation available for distribution to Certificateholders and
its expenditures will be recoverable. If at any time no further amount is
payable under the credit support for a Series of Certificates, and if the
proceeds of any liquidation of the property securing the defaulted Mortgage
Loan, if such property is liquidated, are less than the principal balance of the
defaulted Mortgage Loans plus interest accrued thereon, Certificateholders will
realize a loss in the amount of such difference plus the aggregate of
unreimbursed advances of the Servicer with respect to such Mortgage Loan and
expenses incurred by the Servicer in connection with such proceedings which are
reimbursable under the Pooling Agreement.

REALIZATION UPON DEFAULTED MORTGAGE LOANS

     If any Mortgage Loans become Liquidating Loans, an issuer of credit support
may, if so specified in the related Prospectus Supplement, be obligated to
purchase from the Trustee such Liquidating Loans up to the amount of its
remaining obligations under the related credit support. The Servicer may pay the
purchase price in respect of a Liquidating Loan on behalf of the issuer of
credit support in order to avoid demands or draws under such credit support. If
the ultimate net recovery is equal to or less than the unreimbursed payments
under the related credit support with respect to the Mortgage Loan, the amount
of an issuer's obligations under credit support will be replenished in an amount
equal to the amount of such ultimate net recovery. In the event that the
ultimate net recovery exceeds the


                                      A-18

<PAGE>

unreimbursed payments, such excess will be retained, in the case of a Guaranty
issued by Citicorp, by Citicorp as compensation for the issuance of such
Guaranty, and in the case of other credit support, the Servicer will be entitled
to such proceeds unless otherwise specified in the related Prospectus
Supplement. Such excess will not be applied to replenish the remaining Amount
Available under any credit support. Although a CitiCertificateholder will have
no right to such excess proceeds, the previous reduction in an issuer's
obligations under credit support with respect to that Series will have been
fully restored.

     If a default occurs on a Mortgage Loan at a time when the amount of the
remaining obligations under the related credit support is less than the purchase
price of such Mortgage Loan, no payments under such credit support for the
purchase of such Mortgage Loan or to cover delinquencies may be made with
respect to such default unless otherwise provided in the related Prospectus
Supplement. With respect to Liquidating Loans which are not purchased by or on
behalf of the issuer of credit support, the Issuer or the Servicer will be
obligated to follow such normal practices and procedures as it deems necessary
or advisable to realize upon a defaulted Mortgage Loan. However, the Servicer is
not required under the Pooling Agreement to expend its own funds to foreclose on
a defaulted Mortgage Loan unless it generally determines that foreclosure would
increase the net proceeds of liquidation available for distribution to
Certificateholders and its expenditures will be recoverable. If the Servicer
does not choose to foreclose on a defaulted Mortgage Loan, the Servicer may
accept payment, in connection with a sale by the Mortgagor of the Mortgaged
Property or a retention by the Mortgagor of the Mortgaged Property, in an amount
less than the outstanding balance of the related Mortgage Loan. If the Servicer
does choose to foreclose on a defaulted Mortgage Loan, the Issuer or the
Servicer may (directly or through an assignee) sell the property at a
foreclosure or trustee's or other sale, negotiate with the Mortgagor for a deed
in lieu of foreclosure or, in the event a deficiency judgment is available
against the Mortgagor or other person (see "--Certain Legal Aspects of Mortgage
Loans--Anti-Deficiency Legislation and Other Limitations on Lenders" below for a
description of the limited availability of deficiency judgments), foreclose
against such property and proceed for the deficiency against the appropriate
person. Although the Servicer may elect to pursue deficiency judgments on the
Mortgage Loans, the Servicer is generally not required under the Pooling
Agreement to do so, even if permitted by applicable law. In such circumstances,
the holder of any CitiCertificate evidencing an interest in a Pool with a
Liquidating Loan will realize a loss to the extent that the ultimate net
recovery, after reimbursement to the Issuer or the Servicer of expenses incurred
in connection with the liquidation of such Mortgage Loan, is less than the
outstanding principal balance and accrued and unpaid interest thereon at the
Pass-Through Rate for such Mortgage Loan. The Pooling Agreement with respect to
a Series will require that any property acquired by the Servicer by deed in lieu
of foreclosure with respect to a Liquidating Loan be administered so that it
meets the definition of "foreclosure property" in Section 860G(a)(8) of the Code
at all times, and so that no income from the rental or sale of such property
will be "net income from foreclosure property" within the meaning of Code
Section 860G(c).

     Ordinarily, the holder of collateral acquired through foreclosure maximizes
recovery by providing financing to a new purchaser. As to collateral securing a
Cooperative Loan, any prospective purchaser will generally have to obtain the
approval of the board of directors of the relevant cooperative before purchasing
the shares and acquiring rights under the proprietary lease or occupancy
agreement securing that Cooperative Loan. See "--Certain Legal Aspects of the
Mortgage Loans--Foreclosure on Shares of Cooperatives" below. This approval is
usually based on the purchaser's income and net worth and numerous other
factors. The necessity of acquiring such approval could, however, limit the
number of potential purchasers for those shares and otherwise limit the Issuer's
or the Servicer's ability to sell, and realize the value of, those shares.

     In general, a "tenant-stockholder" (as defined in Code Section 216(b)(2))
of a corporation that qualifies as a "cooperative housing corporation" within
the meaning of Code Section 216(b)(1) is allowed a deduction for amounts paid or
accrued within his taxable year to the corporation representing his
proportionate share of certain interest expenses and certain real estate taxes
allowable as a deduction under Code Section 216(a) to the corporation under Code
Sections 163 and 164. In order for a corporation to qualify under Code Section
216(b)(1) for its taxable year in which such items are allowable as a deduction
to the corporation, such section requires, among other things, that at least 80%
of the gross income of the corporation be derived from its tenant-stockholders.
By virtue of this requirement, the status of a corporation for purposes of Code
Section 216(b)(1) must be determined on a year-to-year basis. Consequently,
there can be no assurance that cooperatives relating to the Cooperative Loans
will qualify under such section for any particular year. In the event that such
a cooperative fails to qualify for one or more years, the value of the
collateral securing any related Cooperative Loans could be significantly
impaired because no deduction would be allowable to tenant-stockholders under
Code Section 216(a) with respect to those years. In view of the significance


                                      A-19

<PAGE>

of the tax benefits accorded tenant-stockholders of a corporation that qualifies
under Code Section 216(b)(1), the likelihood that such a failure would be
permitted to continue over a period of years appears remote.

     If at any time no further amount is payable under any credit support for a
Series of CitiCertificates, the Issuer or the Servicer may expend its own funds
to restore property securing a Liquidating Loan included in such Series which
has sustained uninsured damage, but only if it determines that such restoration
will increase the proceeds to the CitiCertificateholders of liquidation of the
Liquidating Loan after reimbursement of the Issuer or the Servicer for its
expenses.

SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES

     The Issuer's or Servicer's primary compensation for its servicing
activities in respect of a Pool will come from the payment to it of a servicing
fee. A servicing fee will be paid to the Issuer in respect of Mortgage Loans
underlying a Pool as described under "DESCRIPTION OF CERTIFICATES--The Servicer"
in the body of this Prospectus. Such servicing fee paid to the Servicer in
respect of a Pool may be in an amount equal to a fixed annual percentage as
specified in the related Prospectus Supplement of the outstanding principal
balance of such Mortgage Loans on which interest is payable. In such event, the
rate of servicing compensation for each Mortgage Loan in a Pool will be fixed,
and the Pass-Through Rates of the Mortgage Loans will differ based on different
mortgage rates. Accordingly, the weighted average of the fixed Pass-Through
Rates of the Mortgage Loans underlying any Series of CitiCertificates will vary
each month based on the level of principal repayments (including prepayments) on
the underlying fixed rate Mortgage Loans. In such event, because the rate of
servicing compensation is fixed for each Mortgage Loan, disproportionate
principal payments among Mortgage Loans bearing different mortgage rates in a
Pool may affect the yield to the holder of a CitiCertificate, and accordingly,
may affect the market value of such CitiCertificate. Alternatively, if so
specified in the related Prospectus Supplement, the Pass-Through Rate may be the
same (or calculated in the same manner) for each Mortgage Loan in the Pool, and
the rate of servicing compensation with respect to each Mortgage Loan (equal to
the difference between the mortgage rate for such Mortgage Loan and such
Pass-Through Rate) may differ among different Mortgage Loans. In such event,
disproportionate principal payments among Mortgage Loans bearing different
mortgage rates in a Pool will not affect the weighted average Pass-Through Rate,
but may affect the weighted average rate of servicing compensation. In addition,
the rate of servicing compensation and the Pass-Through Rate may both differ
among different Mortgage Loans. Additional information with respect to the
Pass-Through Rates of the Mortgage Loans and the related rates of servicing
compensation will be set forth in the related Prospectus Supplement. As
principal payments are made on the Mortgage Loans, the portion of each monthly
payment which represents interest will decline and thus the primary servicing
compensation will ordinarily decrease as the Mortgage Loans amortize.

     In addition to its primary servicing compensation, the Issuer or Servicer
will retain all prepayment charges, if any, assumption fees and late payment
charges, all to the extent collected from Mortgagors, and has agreed to pay all
such amounts over to any related subservicer. Based upon the Originators'
experience and the experience of the residential financing industry generally
with respect to conventional one- to four-family real estate mortgages, such as
the Mortgage Loans, it appears that compensation from these additional sources
will be negligible in amount.

     The Issuer or the Servicer will be responsible (to the extent specified in
the related Prospectus Supplement) for payment of interest in respect of
prepayments of principal of the Mortgage Loans to be distributed to
CitiCertificateholders in excess of the amount of such interest received from
the Mortgagors.

     The Issuer or the Servicer will pay all expenses incurred in connection
with its servicing of the related Mortgage Loans (subject to limited
reimbursement as described herein), including, without limitation, payment of
the fees and disbursements of the Trustee (to the extent such fees are not
deducted from amounts received on the Mortgage Loans) and independent
accountants, payments of all fees and expenses in connection with the
realization upon defaulted Mortgage Loans, and payment of expenses incurred in
connection with distributions and reports to CitiCertificateholders.

     If no further amount is payable under any credit support for a Series, the
Issuer or the Servicer will be entitled to reimbursement for certain expenses
incurred by it in connection with the liquidation of defaulted Mortgage Loans,
and the holders of CitiCertificates will suffer loss to the extent that the
proceeds of the liquidation proceedings respecting any defaulted Mortgage Loan,
after reimbursement of the Issuer's or the Servicer's expenses, are less than
the principal balance of such Mortgage Loan. In addition, the Servicer will be
entitled to reimbursement of certain expenditures made by it in connection with
the preservation, protection or restoration of the security for a defaulted or
foreclosed Mortgage Loan.

CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS

  Mortgages

     The Real Estate Loans will be secured by either mortgages or deeds of
trust, depending upon the prevailing practice in the state in which the property
subject to a Real Estate Loan is located. A mortgage or a deed of trust creates
a lien upon the real property encumbered by such instrument and represents the
security for the repayment of an obligation that is customarily evidenced by a
promissory note or a bond. It is not prior to the lien for real estate taxes and
assessments and certain other liens. Priority with respect to mortgages and
deeds of trust depends on their terms and generally on the order of recording
with a state, county or municipal office. There are two parties to a mortgage,
the mortgagor, who is the borrower/homeowner or the land trustee (as described
below), and the mortgagee, who is the lender. Under the mortgage instrument, the
mortgagor delivers to the mortgagee a note or bond and the mortgage. In the case
of a land trust, title to the property is held by a land trustee under a land
trust agreement, while the borrower/homeowner is the beneficiary of the land
trust; at origination of a mortgage loan, the borrower executes a separate
undertaking to make payments on the mortgage note. The security arrangements for
a living trust (also known as a family trust or inter vivos trust) are similar
to those for a land trust, except that the borrower executes the mortgage note.
Although a deed of trust is similar to a mortgage, a deed of trust formally has
three parties, the trustor (similar to a mortgagor), who is the homeowner and
may or may not be the borrower, the beneficiary (similar to a mortgagee), who is
the lender, and the trustee, a third-party grantee. Under a deed of trust, the
trustor grants the property, irrevocably until the debt is paid, in trust,
generally with a power of sale, to the trustee to secure payment of the
obligation. The mortgagee's authority under a mortgage and the trustee's
authority under a deed of trust are governed by law, the express provisions of
the mortgage or deed of trust, and, in some cases, the directions of the
beneficiary.

  Cooperatives

     All cooperative apartments relating to the Cooperative Loans are located in
the States of New York, New Jersey, Illinois and Maryland and in the District of
Columbia. The private, non-profit, cooperative apartment corporation owns all
the real property that comprises the project, including the land, separate
dwelling units and all common areas. The cooperative is directly responsible for
project management and, in most cases, payment of real estate taxes and hazard
and liability insurance. If there is a blanket mortgage on the cooperative
apartment building and/or underlying land, as is generally the case, the
cooperative, as project mortgagor, is also responsible for meeting these
mortgage obligations. A blanket mortgage is ordinarily incurred by the
cooperative in connection with the construction or purchase of the cooperative's
apartment building. The interest of the occupant under proprietary leases or
occupancy agreements to which that cooperative is a party are generally
subordinate to the interest of the holder of the blanket mortgage in that
building. If the cooperative is unable to meet the payment obligations arising
under its blanket mortgage, the mortgagee holding the blanket mortgage could
foreclose on that mortgage and terminate all subordinate proprietary leases and
occupancy agreements. Also, the blanket mortgage on a cooperative may provide
financing in the form of a mortgage that does not fully amortize, with a
significant portion of principal being due in one lump sum at final maturity.
The inability of the cooperative to refinance this mortgage and its consequent
inability to make such final payment could lead to foreclosure by the mortgagee
providing the financing. A foreclosure in either event by the holder of the
blanket mortgage could eliminate or significantly diminish the value of any
collateral held by the lender who financed the purchase by an individual
tenant-stockholder of cooperative shares or the collateral securing the
Cooperative Loans.

     The cooperative is owned by tenant-stockholders who, through ownership of
stock, shares or membership certificates in the corporation, receive proprietary
leases or occupancy agreements which confer exclusive rights to occupy specific
units. Generally, a tenant-stockholder of a cooperative must make a monthly
payment to the cooperative representing such tenant-stockholder's pro rata share
of the cooperative's payments for its blanket mortgage, real property taxes,
maintenance expenses and other capital or ordinary expenses. An ownership
interest in a cooperative and accompanying occupancy rights is financed through
a cooperative share loan evidenced by a promissory note and secured by a
security interest in the occupancy agreement or proprietary lease and in the
related cooperative shares. The lender takes possession of the share certificate
and a counterpart of the proprietary lease or occupancy agreement and, if
allowed under state law, a financing statement covering the proprietary lease or
occupancy agreement and the cooperative shares is filed in the appropriate state
and local offices to perfect the


                                      A-21

<PAGE>

lender's interest in its collateral. Subject to the limitations discussed below,
upon default of the tenant-stockholder, the lender may sue for judgment on the
promissory note, dispose of the collateral at a public or private sale or
otherwise proceed against the collateral or tenant-stockholder as an individual
as provided in the security agreement covering the assignment of the proprietary
lease or occupancy agreement and the pledge of cooperative shares. See
"Foreclosure on Shares of Cooperatives" below.

  Foreclosure on Mortgages

     Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust which authorizes
the trustee to sell the property upon any default by the borrower under the
terms of the note or deed of trust. In some states, the trustee must record a
notice of default and send a copy to the borrower-trustor and to any person who
has recorded a request for a copy of a notice of default and notice of sale. In
addition, the trustee in some states must provide notice to any other individual
having an interest in the real property, including any junior lienholders. The
trustor, borrower or any person having a junior encumbrance on the real estate
may, during a reinstatement period, cure the default by paying the entire amount
in arrears plus the costs and expenses incurred in enforcing the obligation.
Generally, state law controls the amount of foreclosure expenses and costs,
including attorney's fees, which may be recovered by a lender. If the deed of
trust is not reinstated, a notice of sale must be posted in a public place and,
in most states, published for a specific period of time in one or more
newspapers. In addition, some state laws require that a copy of the notice of
sale be posted on the property or the courthouse door of the county in which the
property is located, recorded and sent to all parties having an interest in the
real property.

     An action to foreclose a mortgage is an action to recover the mortgage debt
by enforcing the mortgagee's rights under the mortgage. It is regulated by
statutes and rules and subject throughout to the court's equitable powers. For
example, in Texas it is necessary to give both notice of intent to accelerate as
well as notice of acceleration of an installment note, and in New Jersey it is
also necessary to give a notice of intent to foreclose. Generally, a mortgagor
is bound by the terms of the mortgage note and the mortgage as made and cannot
be relieved from his default. However, since a foreclosure action is equitable
in nature and is addressed to a court of equity, the court may relieve a
mortgagor of a default and deny the mortgagee foreclosure on proof that the
mortgagor's default was neither wilful nor in bad faith and that the mortgagee's
action was such as to establish a waiver, or fraud, bad faith, oppressive or
unconscionable conduct as to warrant a court of equity to refuse affirmative
relief to the mortgagee. Under certain circumstances a court of equity may
relieve the mortgagor from an entirely technical default where such default was
not willful.

     A foreclosure action is subject to most of the delays and expenses of other
lawsuits if defenses or counterclaims are interposed, sometimes requiring up to
several years to complete. Substantial delays and expenses may be incurred if
the defaulting mortgagor files a petition under the federal bankruptcy laws
prior to the initiation of a foreclosure action or during its pendency.
Moreover, recent judicial decisions suggest that a non-collusive, regularly
conducted foreclosure sale may be challenged as a fraudulent conveyance,
regardless of the parties' intent, if a court determines that the sale was for
less than fair consideration and such sale occurred while the mortgagor was
insolvent and within one year (or within the statute of limitations if the
trustee in bankruptcy elects to proceed under state fraudulent conveyance law)
of the filing of bankruptcy. Similarly, a suit against the debtor on the
mortgage note or bond may take several years.

     In case of foreclosure under either a mortgage or a deed of trust, the sale
by the referee or other designated officer or by the trustee is a public sale.
However, because of the difficulty potential third party purchasers at the sale
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it is
very often the case that a third party does not purchase the property at the
foreclosure sale. Rather, it is more common for the lender to purchase the
property from the trustee or referee for an amount equal to the principal amount
of the mortgage or deed of trust plus accrued and unpaid interest and the
expenses of foreclosure. Thereafter, the lender will assume the burdens of
ownership, including obtaining casualty insurance, paying real estate taxes and
any special municipal assessments which may have priority over the mortgage and
making such repairs at its own expense as are necessary to render the property
suitable for sale. The lender will commonly obtain the services of a real estate
broker and pay the broker's commission in connection with the sale of the
property. Depending upon market conditions, the ultimate proceeds of the sale of
the property may not equal the lender's investment in the property. Any loss may
be reduced by the receipt of any mortgage insurance proceeds. The


                                      A-22

<PAGE>

Servicer is not required under the Pooling Agreement to expend its own funds to
foreclose on a defaulted Mortgage Loan unless it generally determines that
foreclosure would increase the net proceeds of liquidation available for
distribution to Certificateholders and its expenditures will be recoverable.
There may be circumstances, for example, the possibility of incurring liability
for environmental damage or a substantial decline in the value of the underlying
property, which would cause the Servicer to elect not to foreclose on a
defaulted Mortgage Loan.

     Foreclosure of a mortgage is accomplished in New York, New Jersey and
Florida in most cases, and in Illinois in all cases, by an action in foreclosure
culminating in a judicial sale (or, in the case of Illinois, a judicially
approved sale) of the real property by a court-appointed referee, sales agent or
other official following a judgment of foreclosure. The purposes of a
foreclosure action are to enable the mortgagee to realize upon its security and
to bar the mortgagor, persons with liens subordinate to the foreclosing
mortgagee, and certain other persons with interests in the real property from
their statutory rights and "equity of redemption." The doctrine of equity of
redemption provides that, until the property covered by a mortgage has been sold
in accordance with a properly conducted foreclosure and foreclosure sale, those
having an equity of redemption may redeem the property by paying the entire debt
with interest and, in the event that a foreclosure action is pending, all or
part of the costs of such action. Those having a statutory right or equity of
redemption must be made parties and duly summoned to the foreclosure action in
order for their statutory right or equity of redemption to be barred.

     In Connecticut a court in its discretion may order either a foreclosure by
judicial sale or strict foreclosure. Generally, Connecticut courts grant strict
foreclosure unless the United States is a party or the court upon the motion of
a party or upon its own motion determines that the net value of the mortgaged
property is materially in excess of the debt being foreclosed. If a court orders
strict foreclosure, it will establish a "law day" for each defendant in the
foreclosure action. The period of time between the entry of the judgment of
foreclosure and the first law day will be set by the court as at least twenty
days after the date of the judgment. The first law day will be for the owner of
the mortgaged property, and then, in sequence, there will be a law day for each
party having a lien on, or other interest in, the mortgaged property which is
junior to the foreclosing mortgagee's interest, in inverse order of their
priority. Unless a party assigned a prior law day redeems by paying the debt due
the foreclosing mortgagee in full, each party will have the right on his law day
to redeem the mortgaged property by paying off the foreclosing mortgagee; after
redemption, the redeeming party will own the mortgaged property subject to any
other liens or interests as to which a law day has not passed. If a party fails
to redeem on his law day, his rights in the mortgaged property are extinguished.
If no party redeems, the foreclosing mortgagee becomes the owner of the
mortgaged property, subject to other liens or interests which are prior to the
mortgage foreclosed or as to which the holders thereof were not parties to the
foreclosure action. If the court orders foreclosure by sale rather than strict
foreclosure, a committee is appointed by the court to sell the mortgaged
property at auction. The proceeds of the sale will then be distributed first to
pay the costs of the sale and then to satisfy the debts of the parties in the
order of their priority to the extent the proceeds permit.

     Upon foreclosure of a Connecticut mortgage, a mortgagor who is unemployed
or under-employed may, in certain circumstances, be granted a stay of the
foreclosure proceedings not to exceed six months, and a restructuring of the
mortgage debt to add unpaid interest and certain other charges to the
outstanding principal amount of the debt. The total amount of the restructured
debt may not exceed the larger of the original mortgage debt or 90% of the fair
market value at the time of restructuring and the restructured payments must be
made over the remaining portion of the original term of the mortgage.

     In California, foreclosure can be judicial or nonjudicial. The primary
distinction between a judicial and a nonjudicial foreclosure is that in the case
of a judicial sale a deficiency judgment may be obtained, while in the case of a
non-judicial foreclosure, no deficiency judgment is allowed. Since California
borrowers are protected by anti-deficiency legislation with respect to most
purchase-money deeds of trust, the issuer will, in almost all instances, pursue
non-judicial foreclosure. A second difference between judicial and non-judicial
foreclosures is that in the case of the former, if the beneficiary chooses to
maintain its right to a deficiency judgment, the trustor may redeem the property
by paying the amount bid at the sale plus statutory fees, costs and interest for
a period of three months (when the proceeds of sale are sufficient to pay the
lender in full) or one year (when the sale proceeds are insufficient to pay the
lender in full) after the sale. The purchaser at the sale, whether it be the
lender or a third party, may not demand possession of the property until
expiration of the redemption period; although, the redeemer will be required to
pay reasonable rental value upon redemption.


                                      A-23

<PAGE>

     A lender may accept a deed in lieu of foreclosure instead of pursuing
either judicial or nonjudicial foreclosure. By accepting a deed in lieu of
foreclosure, the lender takes the property back subject to any junior liens,
which would be subordinated or released of record.(1)

     In addition, California law can delay foreclosure and collection of late
charges if a lender participates in the sale of credit disability insurance in
connection with one of its loans and the borrower suffers a disability.

     In Illinois, a borrower in a mortgage foreclosure suit is granted the right
to reinstate a mortgage prior to the expiration of ninety days from the date the
court obtains jurisdiction over all mortgagors in respect of the property
subject to such mortgage foreclosure. In the event such right is exercised, the
delinquent borrower is required to pay only the actual delinquency costs and
reasonable attorney fees, but not any amount which is due as a result of any
acceleration provisions in the note evidencing the debt. As a result, the
borrower may unilaterally reinstate the mortgage loan and terminate the
foreclosure proceedings. In addition, when the lender bids less than the total
debt at the judicial sale, Illinois law provides the borrower with a special
30-day right of redemption in the foreclosure of a single-family residence. Upon
exercise of such right, the borrower need only redeem by paying the amount of
the sale price, plus interest and costs, and not the deficiency. Many Illinois
mortgages, however, give the mortgagors greater contractual rights to reinstate
a mortgage than are granted under Illinois statutes.

  Foreclosure on Shares of Cooperatives

     The cooperative shares owned by the tenant-stockholder and pledged to the
lender are, in almost all cases, subject to restrictions on transfer as set
forth in the cooperative's Certificate of Incorporation and By-laws, as well as
in the proprietary lease or occupancy agreement, and may be canceled by the
cooperative for failure by the tenant-stockholder to pay rent or other
obligations or charges owed by such tenant-stockholder, including mechanics'
liens against the cooperative apartment building incurred by such
tenant-stockholder. The proprietary lease or occupancy agreement generally
permits the cooperative to terminate such lease or agreement in the event an
obligor fails to make payments or defaults in the performance of covenants
required thereunder. Typically, the lender and the cooperative enter into a
recognition agreement which establishes the rights and obligations of both
parties in the event of a default by the tenant-stockholder on its obligations
under the proprietary lease or occupancy agreement. A default by the
tenant-stockholder under the proprietary lease or occupancy agreement will
usually constitute a default under the security agreement between the lender and
the tenant-stockholder.

     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the cooperative will take no action to terminate such lease or
agreement until the lender has been provided with an opportunity to cure the
default. The recognition agreement typically provides that if the proprietary
lease or occupancy agreement is terminated, the cooperative will recognize the
lender's lien against proceeds from a sale of the cooperative apartment,
subject, however, to the cooperative's right to sums due under such proprietary
lease or occupancy agreement. The total amount owed to the cooperative by the
tenant-stockholder, which the lender generally cannot restrict and does not
monitor, could reduce the value of the collateral below the outstanding
principal balance of the cooperative loan and accrued and unpaid interest
thereon.

     Recognition agreements also provide that in the event of a foreclosure on a
cooperative loan, the lender must obtain the approval or consent of the
cooperative as required by the proprietary lease before transferring the
cooperative shares or assigning the proprietary lease. Generally, the lender is
not limited in any rights it may have to dispossess the tenant-stockholders.

(1)  Even a transfer at a nonjudicial foreclosure sale has been held by one
     federal court of appeals to constitute a fraudulent conveyance. The United
     States Court of Appeals for the Ninth Circuit (in which California is
     located), however, has held to the contrary. Amendments to the federal
     bankruptcy laws addressed this conflict, at least in the bankruptcy context
     (as opposed to a state court fraudulent conveyance claim), but not with
     complete clarity. It is probable that a court would interpret these
     amendments to permit challenging a nonjudicial foreclosure sale as a
     fraudulent conveyance if the property is worth significantly more than the
     amount paid at the sale. Citibank Service Corporation, a subsidiary of CFSB
     doing business as Citibank Insurance Agency, sells such insurance in
     connection with Mortgage Loans originated by CFSB. Finally, in California,
     the borrower has until 5 days before a trustee sale to reinstate the loan.

     In New York and New Jersey, foreclosure on the cooperative shares is
accomplished by a sale in accordance with the provisions of Article 9 of the
Uniform Commercial Code (the "UCC") and the security agreement relating to those
shares. Article 9 of the UCC requires that a sale be conducted in a
"commercially reasonable" manner. Whether a foreclosure sale has been conducted
in a "commercially reasonable" manner will depend on the facts in each case. In
determining commercial reasonableness, a court will look to the notice given the
debtor and the method, manner, time, place and terms of the foreclosure.
Generally, a sale conducted according to the usual practice of banks selling
similar collateral will be considered reasonably conducted. Article 9 of the UCC
provides that the proceeds of the sale will be applied first to pay the costs
and expenses of the sale and then to satisfy the indebtedness secured by the
lender's security interest. The recognition agreement, however, generally
provides that the lender's right to reimbursement is subject to the right of the
cooperative corporation to receive sums due under the proprietary lease or
occupancy agreement. If there are proceeds remaining, the lender must account to
the tenant-stockholder for the surplus. Conversely, if a portion of the
indebtedness remains unpaid, the tenant-stockholder is generally responsible for
the deficiency. See "Anti-Deficiency Legislation and Other Limitations on
Lenders" below.

     The Servicer is not required under the Pooling Agreement to expend its own
funds to foreclose on a defaulted Mortgage Loan unless it generally determines
that foreclosure would increase the net proceeds of liquidation available for
distribution to Certificateholders and its expenditures will be recoverable.
There may be circumstances, for example, the possibility of incurring liability
for environmental damage or a substantial decline in the value of the underlying
property, which would cause the Servicer to elect not to foreclose on a
defaulted Mortgage Loan.

  Rights of Redemption

     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the trustor or mortgagor and foreclosed junior lienors are given a
statutory period in which to redeem the property from the foreclosure sale. The
right of redemption should be distinguished from the equity of redemption, which
is a nonstatutory right that must be exercised prior to the foreclosure sale. In
some states, redemption may occur only upon payment of the entire principal
balance of the loan, accrued interest and expenses of foreclosure. In other
states, redemption may be authorized if the former borrower pays only a portion
of the sums due. The effect of a statutory right of redemption is to diminish
the ability of the lender to sell the foreclosed property. The right of
redemption would defeat the title of any purchaser from the lender subsequent to
foreclosure or sale under a deed of trust. Consequently, the practical effect of
a right of redemption is to force the lender to retain the property and pay the
expenses of ownership until the redemption period has run. In some states, there
is no right to redeem property after a trustee's sale under a deed of trust or
after a foreclosure action.

  Anti-Deficiency Legislation and Other Limitations on Lenders

     Certain states have imposed statutory prohibitions which limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage. In some
states, statutes limit the right of the beneficiary or mortgagee to obtain a
deficiency judgment against the borrower following foreclosure or sale under a
deed of trust. A deficiency judgment is a personal judgment against the former
borrower equal in most cases to the difference between the net amount realized
upon the public sale of the real property and the amount due to the lender.
Other statutes require the beneficiary or mortgagee to exhaust the security
afforded under a deed of trust or mortgage by foreclosure in an attempt to
satisfy the full debt before bringing a personal action against the borrower.
Finally, other statutory provisions limit any deficiency judgment against the
former borrower following a judicial sale to the excess of the outstanding debt
over the fair market value of the property at the time of the public sale. The
purpose of these statutes is generally to prevent a beneficiary or a mortgagee
from obtaining a large deficiency judgment against the former borrower as a
result of low or no bids at the judicial sale.

     Although the Servicer may elect to pursue deficiency judgments on the
Mortgage Loans, the Servicer is generally not required under the Pooling
Agreement to do so, even if permitted by applicable law.

     For Mortgage Loans Secured by Property in New York. Section 1371 of the New
York Real Property Actions and Proceedings Law provides that no award of a
deficiency judgment can be made unless the court has personal jurisdiction over
the defendant. Moreover, if no motion for a deficiency judgment is made within
90 days of the consummation of the sale by the delivery of the deed to the
purchaser, the proceeds of the foreclosure sale, regardless of the amount, are
deemed in full satisfaction of the mortgage debt and no right to recover any
deficiency in any action or proceeding exists. Section 1301 of the same law
limits the mortgagee's right to bring separate actions for the


                                      A-25

<PAGE>

mortgage debt and for foreclosure. While the foreclosure action is pending, or
after final judgment for the plaintiff therein, no other action may be commenced
or maintained to recover any part of the mortgage debt without leave of the
court in which the foreclosure action was brought. A deficiency judgment is
limited to an amount equal to the judgment amount in the foreclosure action,
less (i) the fair and reasonable market value of the mortgaged property as of
the date of the foreclosure sale or such nearest earlier date as there shall
have been any market value thereof as determined by the court or (ii) the sale
price of the property at the foreclosure sale, whichever shall be the higher.

     Section 254-b of the New York Real Property Law also places a limitation on
the mortgagee with respect to late payment charges. Where the mortgage contains
a provision giving the mortgagee the right to collect a late payment charge on
any installment that has become due and remains unpaid, such charge cannot be
more than 2% of the delinquent installment and cannot be imposed on any
installment paid within 15 days of the due date. In addition, late payment
charges cannot be deducted from the regular installment payments; they must be
separately charged and collected by the mortgagee.

     In New York the mortgagee of a loan on a residential leasehold property can
foreclose such mortgage by maintaining a traditional equitable foreclosure
action. Any rent or taxes paid by the mortgagee following default by the
mortgagor may be added to the unpaid balance of the mortgage debt upon
foreclosure. A judgment of foreclosure of a leasehold, however, results in a
public auction only if the mortgage expressly so provides, whereas judgment of
foreclosure on a real property mortgage would result in a public auction in all
cases. In the absence of an express provision, in a leasehold mortgage, the
mortgagee can only recover a money judgment. In this event, the mortgagee may
follow traditional enforcement procedures. In addition to enforcement of
judgment remedies, the leasehold interest may then be subject to a post-judgment
sale pursuant to an execution.

     For Mortgage Loans Secured by Property in New Jersey. Under New Jersey law
(N.J.S.A. 2A:50-1 et seq.) an action for deficiency judgment must be commenced
within three months from the date of the foreclosure sale of a mortgaged
premises. In a deficiency action, judgment will be rendered only for the balance
due on the debt and interest and costs of the action. The obligor under the note
may file an answer in the action for deficiency, disputing the amount of the
deficiency sued for. The court will determine the amount of the deficiency by
deducting from the debt the amount determined as the fair market value of the
premises.

     In New Jersey, the commencement of a deficiency action reopens the
mortgagor's right of redemption for a period of six months after the entry of
any deficiency judgment, which could have an adverse effect on the ability to
transfer good title to the mortgaged premises during this period.

     For Mortgage Loans Secured by Property in Connecticut. If the mortgagee
took title to the mortgaged property under strict foreclosure but the mortgaged
property had value lower than the debt, Connecticut law permits the mortgagee to
move for a deficiency judgment in the amount of the difference within 30 days
after the redemption period has expired. If there was foreclosure by sale and
the proceeds of sale were insufficient to discharge the mortgage debt in full,
the mortgagee may obtain a deficiency judgment for the difference. If, however,
the sales price is less than the value of the mortgaged property as found by the
court, one half of the difference between such value and the sales price must be
credited against the deficiency claim of the person who sought foreclosure by
sale.

     For Mortgage Loans Secured by Property in California. The rule in
California commonly known as the "one-action rule" provides that a lender must
include all claims in one action and must foreclose its security before seeking
to impose any personal liability. The anti-deficiency rules limit the recovery
of personal judgments. If a foreclosure is conducted by way of a nonjudicial
foreclosure sale, California law prohibits the recovery of a deficiency
judgment. In addition, a deficiency judgment is prohibited even if judicial
foreclosure is pursued when a lender finances the purchase price of residential
real property and the property has four or fewer units and is occupied by the
purchaser. Because most mortgage loans fall into this category, the Issuer
intends to pursue nonjudicial foreclosure. While it is possible to sue the
borrower for any fraud or waste, it generally is not practical to do so.

     For Mortgage Loans Secured by Property in Texas. In Texas most foreclosures
are non-judicial. However, it is necessary to give both notice of intent to
accelerate as well as notice of acceleration of the installment note unless
proper waiver language is included in the note. If the real property is used as
the debtor's residence, the debtor must be given at least 20 days to cure the
default before the entire debt is due and notice of sale is given. Any suit for
a deficiency judgment must be brought within two years after the date of
foreclosure. During the pendency of such suit, the debtor has the right to
request the court to determine the fair market value of the property foreclosed
upon. In the event the court determines that the fair market value of the
property is greater than the bid price paid at foreclosure, the debtor is
entitled to an offset against the deficiency claim in the amount by which the
fair market value exceeds the bid price.

     For Mortgage Loans Secured by Property in Illinois. In Illinois, if the
price at the foreclosure sale is less than the total amount adjudicated due in
the judgment of foreclosure plus statutory interest, certain advances and costs
incurred at the time of judicial sale, the mortgagee may obtain deficiency
judgment against the mortgagor provided that there is personal jurisdiction over
the mortgagor.

     For Mortgage Loans Secured by Property in Florida. Under Florida law, if
the fair market value of the mortgaged property at the time of the foreclosure
sale is less than the debt of the final judgement, the mortgagee may seek a
deficiency judgment, either as part of the foreclosure action or in a separate
action on the note. The decision whether to grant a deficiency judgment sought
as part of the foreclosure action lies within the sound judicial discretion of
the court but is subject to any equitable defenses by the borrower. No award of
a deficiency judgment can be made, either as part of or separately from the
foreclosure action, unless the court has personal jurisdiction over the
defendant. A request for a deficiency judgment is subject to dismissal for lack
of prosecution if the deficiency relief is not sought within one year from the
foreclosure sale date.

     For Cooperative Loans. Generally, Article 9 of the UCC governs foreclosure
on cooperative shares and the related proprietary lease or occupancy agreement
in New York or New Jersey. Some courts have interpreted section 9-504 of the UCC
to prohibit a deficiency award unless the creditor establishes that the sale of
the collateral (which, in the case of a Cooperative Loan, would be the shares of
the cooperative and the related proprietary lease or occupancy agreement) was
conducted in a commercially reasonable manner.

     Section 254-b of the New York Real Property Law relating to late payment
charges, as discussed above, also applies to a note evidencing a cooperative
loan.

     For all Mortgage Loans. In addition to laws limiting or prohibiting
deficiency judgments, numerous other statutory provisions, including the federal
bankruptcy laws and state laws affording relief to debtors, may interfere with
or affect the ability of the secured mortgage lender to realize upon its
security. For example, numerous statutory provisions under the United States
Bankruptcy Code, 11 U.S.C. Sections 101 et seq., (the "Bankruptcy Code") may
interfere with or affect the ability of the Servicer to obtain payment of a
Mortgage Loan, to realize upon collateral and/or to enforce a deficiency
judgment. For example, under federal bankruptcy law, virtually all actions
(including foreclosure actions and deficiency judgment proceedings) are
automatically stayed upon the filing of a bankruptcy petition, and often no
interest or principal payments are made during the course of the bankruptcy
proceeding. In a case under the Bankruptcy Code, the secured party is precluded
from foreclosing without authorization from the bankruptcy court. In addition, a
court with federal bankruptcy jurisdiction may permit a debtor through his or
her Chapter 11 or Chapter 13 plan to cure a monetary default in respect of a
Mortgage Loan by paying arrearages within a reasonable time period and
reinstating the original mortgage loan payment schedule even though the lender
accelerated the mortgage loan and final judgment of foreclosure had been entered
in state court (provided no foreclosure sale had yet occurred) prior to the
filing of the debtor's petition. Some courts with federal bankruptcy
jurisdiction have approved plans, based on the particular facts of the case,
that effected the curing of a mortgage loan default by paying arrearages over a
number of years.

     If a Mortgage Loan is secured by property not consisting solely of the
debtor's principal residence, the Bankruptcy Code also permits such Mortgage
Loan to be modified. Such modifications may include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
and reducing the lender's security interest to the value of the property, thus
leaving the lender in the position of a general unsecured creditor for the
difference between the value of the property and the outstanding balance of the
Mortgage Loan. Some courts have permitted such modifications when the Mortgage
Loan is secured both by the debtor's principal residence and by personal
property.

     If a court relieves a borrower's obligation to repay amounts otherwise due
on a Mortgage Loan, the Servicer will not be required to advance such amounts,
and any loss in respect thereof will be borne by the Certificateholders.

     The IRS Code provides priority to certain tax liens over the lien of the
mortgage or deed of trust. The laws of some states provide priority to certain
tax liens over the lien of the mortgage or deed of trust. Numerous federal and
some state consumer protection laws impose substantive requirements upon
mortgage lenders in connection with the origination, servicing, and enforcement
of mortgage loans. These laws include the federal Truth in Lending Act, Real
Estate Settlement Procedures Act, Equal Credit Opportunity Act, Fair Credit
Billing Act, Fair Debt Collection Practices Act, Fair Credit Reporting Act, and
related statutes and regulations. These federal laws and state laws impose
specific statutory liabilities upon lenders who originate or service mortgage
loans and who fail to comply with the provisions of the law. In some cases, this
liability may affect assignees of the mortgage loans.

  Enforceability of Certain Provisions, Prepayment Charges and Prepayments

     Unless the Prospectus Supplement indicates otherwise, Mortgage Loans
representing at least 90% of the aggregate Adjusted Balance of the Mortgage
Loans in a Fixed Rate Pool will contain due-on-sale clauses. Generally, ARMs in
an ARM Pool will contain due-on-sale clauses permitting the mortgagee to
accelerate only in situations where its security may be impaired. These clauses
permit the lender to accelerate the maturity of the loan if the borrower sells,
transfers or conveys the property or, in the case of a land trust, the
beneficial interest therein is transferred. The enforceability of these clauses
has been impaired in various ways in certain states by statute or decisional
law. The ability of mortgage lenders and their assignees and transferees to
enforce due-on-sale clauses was addressed by the Garn-St Germain Depository
Institutions Act of 1982 (the "Garn-St Germain Act") which was enacted on
October 15, 1982. This legislation, subject to certain exceptions, preempts
state constitutional, statutory and case law that prohibits the enforcement of
due-on-sale clauses. Exempted from this preemption are mortgage loans
(originated other than by federal savings and loan associations and federal
savings banks) that were made or assumed during the period beginning on the date
certain states ("Window Period States"), by statute or final appellate court
decision having statewide effect, prohibited the exercise of due-on-sale clauses
and ending on October 15, 1982 ("Window Period Loans"). Due-on-sale clauses
contained in mortgage loans originated by federal savings and loan associations
or federal savings banks are fully enforceable pursuant to regulations of the
Federal Home Loan Bank Board (now OTS) which preempt state law restrictions on
the enforcement of due-on-sale clauses. Mortgage loans originated by such
institutions are therefore not deemed to be Window Period Loans.

     Though neither the Garn-St Germain Act nor the Federal Home Loan Bank Board
regulations promulgated thereunder actually names the Window Period States,
FHLMC has taken the position, in prescribing mortgage loan servicing standards
with respect to mortgage loans which it has purchased, that the Window Period
States are: Arizona, Arkansas, California, Colorado, Florida, Georgia, Iowa,
Michigan, Minnesota, New Mexico, Utah and Washington. In regulations issued on
November 8, 1983, the Comptroller of the Currency indicated that certain
mortgage loans which were originated by national banks prior to October 15, 1982
and which were secured by property located in the states listed above were
Window Period Loans. These regulations limit the applicability of state law
restrictions on the enforcement of due-on-sale clauses with respect to Window
Period Loans originated by national banks. The National Credit Union
Administration issued final regulations on December 3, 1982, providing that
due-on-sale clauses contained in Window Period Loans originated by federal
credit unions are fully enforceable, notwithstanding state law restrictions.
Under the Garn-St Germain Act, unless a Window Period State took action by
October 15, 1985, the end of the Window Period, to further regulate enforcement
of due-on-sale clauses, such clauses would become enforceable even in Window
Period Loans. Four of the Window Period States (Minnesota, Michigan, New Mexico
and Utah) have taken actions which restrict the enforceability of due-on-sale
clauses in Window Period Loans beyond October 15, 1985. The actions taken vary
among such states. The Garn-St Germain Act also set forth nine specific
instances in which no mortgage lender covered by the Garn-St Germain Act may
exercise a due-on-sale clause, notwithstanding the fact that a transfer of the
property may have occurred. The inability to enforce a due-on-sale clause may
result in a Mortgage Loan bearing an interest rate below the current market rate
being assumed by a new home buyer rather than being paid off, which may have an
impact upon the average life of the Mortgage Loans underlying a Series and the
number of such Mortgage Loans which may be outstanding until maturity. Upon
foreclosure, courts have imposed general equitable principles. The equitable
principles are generally designed to relieve the borrower from the legal effect
of his defaults under the loan documents. Examples of judicial remedies that
have been fashioned include judicial requirements that the lender undertake
affirmative and expensive actions to determine the causes for the borrower's
default and the likelihood that the borrower will be able to reinstate the loan.
In some cases, courts have substituted their judgment for the lender's judgment
and have required that lenders reinstate loans or recast payment schedules in
order to accommodate borrowers who are suffering from temporary financial
disability. In other cases, courts have limited the right of a lender to
foreclose if the default under the mortgage instrument is not monetary, such as
the borrower's failure to adequately maintain the property or the borrower's
execution of a second mortgage or deed of trust affecting the property. Finally,
some courts have been faced with the issue of whether federal or state
constitutional provisions reflecting due process concerns for adequate notice
require that borrowers under deeds of trust or mortgages receive notices in
addition to the statutorily prescribed minimums. For the most part, these cases
have upheld the notice provisions as being reasonable or have found that the
sale by a trustee under a deed of trust, or under a mortgage having a power of
sale, does not involve sufficient state action to afford constitutional
protections to the borrower.

     All conventional single-family Mortgage Loans originated by Citibank may be
prepaid in full or in part at any time, without penalty.

     New Jersey statutes (N.J.S.A. 46:10B-2,3) provide that most New Jersey
residential mortgage loans may be prepaid in full at any time without penalty,
and that partial prepayments may be made in an amount not exceeding 33-1/3% of
the face amount of the mortgage loan in any six-month period without penalty.

     California law regarding prepayment penalties is very complex. Whether a
lender can enforce a prepayment penalty depends in the first instance upon
whether the documents give the borrower the right to prepay or the lender the
right to charge a prepayment penalty. Other considerations are the date the loan
was originated, the amount of the loan, whether the loan was a fixed rate or a
variable rate loan, the kind of property securing the loan and when the borrower
wishes to make the prepayment. Federal savings and loan law prohibits the
imposition of prepayment penalties upon the exercise of a due-on-sale clause or
the failure to approve an assumption by a qualified transferee and the
subsequent transfer by the borrower of the property to that transferee and
prepayment of the loan in full.

     Beginning on January 15, 1991, CFSB's California branches' standard forms
for 15-year fixed rate tiered-payment Mortgage Loans provide for a penalty for
full or partial prepayment of up to six months' interest during the first 12
months following origination.

     In Illinois, whenever the annual rate of interest exceeds 8% for a loan
secured by residential real estate, it is unlawful to provide for a prepayment
penalty.

     Most conventional single-family mortgage loans originated by the Florida
branches of CFSB may be prepaid in full or in part without penalty. The
regulations of the Federal Home Loan Bank Board prohibit the imposition of a
prepayment penalty or equivalent fee for or in connection with the acceleration
of a loan by exercise of a due-on-sale clause. A mortgagee to whom a prepayment
in full has been tendered may be compelled to give either a release of the
mortgage or an instrument assigning the existing mortgage to a refinancing
lender.

     Under New York law, a prepayment penalty may not be charged on any loan
secured by a one- to six-family residence occupied by the owner or certificates
of stock in a cooperative corporation, where the interest rate exceeds 6% per
annum, if prepayment is made on or after one year from the making of the loan.

  Applicability of Usury Laws

     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V"), provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. A similar federal statute
was in effect with respect to mortgage loans made during the first three months
of 1980. The OTS as successor to the Federal Home Loan Bank Board is authorized
to issue rules and regulations and to publish interpretations governing
implementation of Title V. The statute authorized the states to reimpose
interest rate limits by adopting, before April 1, 1983, a law or constitutional
provision which expressly rejects an application of the federal law. In
addition, even where Title V is not so rejected, any state is authorized by the
law to adopt a provision limiting discount points or other charges on mortgage
loans covered by Title V. Certain states have taken action to reimpose interest
rate limits and/or to limit discount points or other charges.

     The Issuer has been advised by counsel that a court interpreting Title V
would hold that Mortgage Loans related to a Series originated on or after
January 1, 1980 are subject to federal preemption. Therefore, in a state that
has not taken the requisite action to reject application of Title V or to adopt
a provision limiting discount points or other charges prior to origination of
such Mortgage Loans, any such limitation under such state's usury law would not
apply to such Mortgage Loans.

     In any state in which application of Title V has been expressly rejected or
a provision limiting discount points or other charges is adopted, no Mortgage
Loans related to a Series originated after the date of such state action will be
eligible for inclusion in a Pool if such mortgage loans bear interest or provide
for discount points or charges in excess of permitted levels. No mortgage loan
related to a Series originated prior to January 1, 1980 will bear interest or
provide for discount points or charges in excess of permitted levels.

  Adjustable Interest Rate Mortgage Loans

     Adjustable interest rate mortgage loans originated by non-federally
chartered lenders have historically been subject to a variety of restrictions.
Such restrictions differed from state to state, resulting in difficulties in
determining whether a particular alternative mortgage instrument originated by a
state-chartered lender complied with applicable law. These difficulties were
alleviated substantially as a result of the enactment of Title VIII of the
Garn-St Germain


                                      A-29

<PAGE>

Act ("Title VIII"). Title VIII provides that, notwithstanding any state law to
the contrary, state-chartered banks may originate "alternative mortgage
instruments" (including adjustable rate mortgage loans) in accordance with
regulations promulgated by the Comptroller of the Currency with respect to
origination of alternative mortgage instruments by national banks;
state-chartered credit unions may originate alternative mortgage instruments in
accordance with regulations promulgated by the National Credit Union
Administration with respect to origination of alternative mortgage instruments
by federal credit unions and all other non-federally chartered housing
creditors, including state-chartered savings and loan associations; and
state-chartered savings banks and mortgage banking companies may originate
alternative mortgage instruments in accordance with the regulations promulgated
by the Federal Home Loan Bank Board (now OTS) with respect to origination of
alternative mortgage instruments by federal savings and loan associations. Title
VIII provides that any state may reject applicability of the provisions of Title
VIII by adopting, prior to October 15, 1985, a law or constitutional provision
expressly rejecting the applicability of such provisions. Certain states have
taken such action.

     The Issuer has been advised by its counsel that it is their opinion that a
court interpreting Title VIII would hold that adjustable interest rate mortgage
loans which were originated by state-chartered lenders before the date of
enactment of any state law or constitutional provision rejecting applicability
of Title VIII would not be subject to state laws imposing restrictions or
prohibitions on the ability of state-chartered lenders to originate alternative
mortgage instruments.

     All of the ARMs which were originated by a state-chartered lender after the
enactment of a state law or constitutional provision rejecting the applicability
of Title VIII complied with applicable state law. All of the ARMs which were
originated by federally chartered lenders or which were originated by
state-chartered lenders prior to enactment of a state law or constitutional
provision rejecting the applicability of Title VIII were originated in
compliance with all applicable federal regulations.

ENVIRONMENTAL CONSIDERATIONS

     A lender may be subject to unforeseen environmental risks when taking a
security interest in real or personal property. Property subject to such a
security interest may be subject to federal, state, and local laws and
regulations relating to environmental protection. Such laws may regulate, among
other things: emissions of air pollutants; discharges of wastewater or storm
water; generation, transport, storage or disposal of hazardous waste or
hazardous substances; operation, closure and removal of underground storage
tanks; removal and disposal of asbestos-containing materials; management of
electrical or other equipment containing polychlorinated biphenyls ("PCBs").
Failure to comply with such laws and regulations may result in significant
penalties, including civil and criminal fines.

     Under the laws of certain states, environmental contamination on a property
may give rise to a lien on the property to ensure the availability and/or
reimbursement of cleanup costs. Generally, all subsequent liens on such property
are subordinated to such a lien and, in some states, even prior recorded liens
are subordinated to such liens ("Superliens"). In the latter states, the
security interest of the Trustee in a property that is subject to such a
Superlien could be adversely affected.

     Under the federal Comprehensive Environmental Response, Compensation and
Liability Act, as amended ("CERCLA"), and under state law in certain states, a
secured party which takes a deed in lieu of foreclosure, purchases a mortgaged
property at a foreclosure sale, operates a mortgaged property or undertakes
certain types of activities that may constitute "management" of the property may
become liable in certain circumstances for the costs of remedial action
("Cleanup Costs") if hazardous wastes or hazardous substances have been released
or disposed of on the property. Such Cleanup Costs may be substantial and could
exceed the value of the property and the aggregate assets of the owner or
operator. CERCLA imposes strict, as well as joint and several, liability for
environmental remediation and/or damage costs on several classes of "potentially
responsible parties," including current "owners and/or operators" of property,
irrespective of whether those owners or operators caused or contributed to
contamination on the property. In addition, owners and operators of properties
that generate hazardous substances that are disposed of at other "off-site"
locations may be held strictly, jointly and severally liable for environmental
remediation and/or damages at those off-site locations. Many states also have
laws that are similar to CERCLA. Liability under CERCLA or under similar state
law could exceed the value of the property itself as well as the aggregate
assets of the property owner.

     The law is unclear as to whether and under what precise circumstances
Cleanup Costs, or the obligation to take remedial actions, could be imposed on a
secured lender such as the Trust. Under the laws of some states and under


                                      A-30

<PAGE>

CERCLA, a lender may be liable as an "owner or operator" for costs of addressing
releases or threatened releases of hazardous substances on a mortgaged property
if such lender or its agents or employees have "participated in the management"
of the operations of the borrower, even though the environmental damage or
threat was caused by a prior owner or current owner or operator or other third
party. Excluded from CERCLA's definition of "owner or operator," is a person
"who without participating in the management of . . . [the] facility, holds
indicia of ownership primarily to protect his security interest" (the
"secured-creditor exemption"). This exemption for holders of a security interest
such as a secured lender applies only to the extent that the lender seeks to
protect its security interest in the contaminated facility or property. Thus, if
a lender's activities begin to encroach on the actual management of such
facility or property, the lender faces potential liability as an "owner or
operator" under CERCLA. Similarly, when a lender forecloses and takes title to a
contaminated facility or property, the lender may incur potential CERCLA
liability in various circumstances, including among others, when it holds the
facility or property as an investment (including leasing the facility or
property to a third party), fails to market the property in a timely fashion or
fails to properly address environmental conditions at the property or facility.

     The Resource Conservation and Recovery Act, as amended ("RCRA"), contains a
similar secured-creditor exemption for those lenders who hold a security
interest in petroleum underground storage tanks ("USTs") or in real estate
containing a UST, or that acquire title to a petroleum UST or facility or
property on which such a UST is located. As under CERCLA, a lender may lose its
secured-creditor exemption and be held liable under RCRA as a UST owner or
operator if such lender or its employees or agents participate in the management
of the UST. And, if the lender takes title to or possession the UST or the real
estate containing the UST, under certain circumstances the secured-creditor
exemption may be deemed to be unavailable.

     Court decisions have taken varying views of the scope of the
secured-director exemption, leading to administrative and legislative efforts to
provide guidance to lenders on the scope of activities that would trigger CERCLA
and/or RCRA liability. Until recently, these efforts have failed to provide
substantial guidance.

     On September 30, 1996, however, the President signed into law legislation
intended to clarify the scope of the secured-creditor exemption under both
CERCLA and RCRA. This legislation more explicitly defined the kinds of
"participation in management" that would trigger liability under CERCLA and
specified certain activities that would not constitute "participation in
management" or otherwise result in a forfeiture of the secured-creditor
exemption prior to foreclosure or during a workout period. The legislation also
clarifies the extent of protection against liability under CERCLA in the event
of foreclosure. The legislation also authorizes certain regulatory
clarifications of the scope of the secured-creditor exemption for purposes of
RCRA, similar to the statutory protections under CERCLA. However, since the
courts have not yet had the opportunity to interpret the new statutory
provisions, the scope of the additional protections offered by the new law is
not fully defined. It also is important to note that the new legislation does
not offer complete protection to lenders and that the risk of liability remains.

     If a secured lender does become liable, it may be entitled to bring an
action for contribution against the owner or operator who created the
environmental contamination or against some other liable party, but that person
or entity may be bankrupt or otherwise judgment-proof. It is therefore possible
that cleanup or other environmental liability costs could become a liability of
the Trust and occasion a loss to the Trust and to Certificateholders in certain
circumstances. The new secured creditor amendments to CERCLA also affect the
potential for liability in actions by either a state or a private party under
other federal or state laws which may impose liability on "owners or operators"
but do not incorporate the secured-creditor exemption.

     Traditionally, residential mortgage lenders have not taken steps to
evaluate whether hazardous wastes or hazardous substances are present with
respect to any mortgaged property prior to the origination of the mortgage loan
or prior to foreclosure or accepting a deed-in-lieu of foreclosure. Accordingly,
neither the Issuer nor any Originator has made such evaluations prior to the
origination of the Mortgage Loans nor does the Issuer require that such
evaluations be made by originators who have sold the Mortgage Loans to it.
Neither the Issuer nor the Servicer is required to undertake any such
evaluations prior to foreclosure or accepting a deed-in-lieu of foreclosure. The
Issuer does not make any representations or warranties or assume any liability
with respect to: the environmental condition of such property; the absence or
presence of hazardous wastes or hazardous substances on any Mortgaged Property;
any casualty resulting from the presence or effect of hazardous wastes or
hazardous substances on, near or emanating from such property; or the impact of
any environmental condition or the presence of any substance on or near the
property on the prospective performance of the Mortgage Loans or the compliance
of any Mortgaged Property with any environmental laws, nor is any agent, person
or entity otherwise affiliated with the Issuer authorized or able to make any
such representation, warranty or assumption of liability relating to any
Mortgaged Property.

                                                                      APPENDIX B

                             THE AGENCY CERTIFICATES

     This Appendix describes GNMA, FHLMC, FNMA, their respective Mortgage
Certificates, the underlying mortgage loans and certain related matters.

GNMA

     The Government National Mortgage Association ("GNMA") is a wholly-owned
corporate instrumentality of the United States within the Department of Housing
and Urban Development. Section 306(g) of Title III of the National Housing Act
of 1934, as amended (the "Housing Act"), authorizes GNMA to guarantee the timely
payment of the principal of and interest on certificates ("GNMA Certificates")
that are based on and backed by, and represent an interest in, a pool of
mortgage loans insured by the Federal Housing Administration ("FHA") under the
Housing Act ("FHA Loans") or Title V of the Housing Act of 1949, or partially
guaranteed by the United States Veterans Administration ("VA") under the
Servicemen's Readjustment Act of 1944, as amended, or Chapter 37 of Title 38,
United States Code, or by pools of other eligible mortgage loans.

     Section 306(g) of the Housing Act provides that "the full faith and credit
of the United States is pledged to the payment of all amounts which may be
required to be paid under any guaranty under this subsection." In order to meet
its obligations under such guaranty, GNMA is authorized, under Section 306(d) of
the Housing Act, to borrow from the United States Treasury in an amount which is
at any time sufficient to enable GNMA, with no limitations as to amount, to
perform its obligations under its guarantee. 

GNMA CERTIFICATES

     All of the GNMA Certificates will be "fully modified pass-through"
mortgage-backed certificates issued and serviced by issuers approved by GNMA or
by FNMA as a seller-servicer of FHA Loans or VA Loans or by both entities. The
mortgage loans underlying GNMA Certificates may consist of FHA Loans secured by
mortgages on one-to four-family residential properties or multifamily
residential properties, mortgage loans partially guaranteed by the VA ("VA
Loans"), and other mortgage loans eligible for inclusion in mortgage pools
underlying GNMA Certificates which may be level payment mortgage loans
(including "buydown" mortgage loans) or graduated payment mortgage loans each
secured by a first lien on a one-to four-family residential property.

     Except in the case of GNMA Certificates backed by graduated payment
mortgage loans, each GNMA Certificate provides for the payment by or on behalf
of the issuer of the GNMA Certificate to the registered holder of such GNMA
Certificate of monthly payments of principal and interest equal to the
registered holder's proportionate interest in the aggregate amount of the
monthly scheduled principal and interest payments on each underlying eligible
mortgage loan, less servicing and guaranty fees aggregating the excess of the
interest on such eligible mortgage loans over the pass-through rate of such GNMA
Certificate. In addition, each payment to a GNMA Certificateholder will include
proportionate pass-through payments to such holder of any prepayments of
principal of the mortgage loan underlying the GNMA Certificate, and the holder's
proportionate interest in the remaining principal balance in the event of a
foreclosure or other disposition of any such mortgage loan.

     GNMA Certificates may be issued under either the GNMA I program ("GNMA I
Certificates") or the GNMA II program ("GNMA II Certificates"). Although the
holder of a GNMA Certificate has essentially the same rights with respect to a
GNMA Certificate issued under either program, a principal difference between the
two programs is that under the GNMA I program payments will be made directly by
the issuer of the GNMA I Certificate to the registered holder, while under the
GNMA II program payments will be made to the registered holder through Chemical
Bank as paying agent. A further difference between the two programs is that
under the GNMA I program single issuer approach, an individual GNMA issuer
assembles a pool of mortgages against which it issues and markets GNMA I
Certificates, while under the GNMA II program multiple issuer pools may be
formed through the aggregation of loan packages of more than one GNMA issuer.
Under this option, packages submitted by various GNMA issuers for a particular
issue date and interest rate are aggregated into a single pool which backs a
single issue of GNMA II Certificates. However, single issuer pools may be formed
under the GNMA II program as well.

                                      B-1
<PAGE>

     If specified in the related Prospectus Supplement, GNMA Certificates
included in the Pool for a Series of CitiCertificates may be held on deposit at
the Participants Trust Company ("PTC"), a limited trust company organized under
the banking laws of the State of New York. PTC operates a private sector,
industry owned depository and settlement facility for book-entry transfer of
interests in GMNA Certificates. Distribution of principal of and interest on
such GNMA Certificate held through PTC will be credited by PTC to the PTC
participant to whose account the GNMA Certificate is credited.

     All mortgage loans underlying a particular GNMA I Certificate must have the
same annual interest rate (except for pools of mortgages secured by mobile
homes). The annual interest rate on each GNMA I Certificate is 50 basis points
less than the annual interest rate on the mortgage loans included in the pool of
mortgages backing such GNMA I Certificate.

     Mortgages underlying a particular GNMA II Certificate may have annual
interest rates that vary from each other by up to 100 basis points. The annual
interest rate on each GNMA II Certificate will be between 50 basis points and
150 basis points per annum less than the highest annual interest rate on the
mortgage loans included in the pool of mortgages backing such GNMA II
Certificate.

     All of the GNMA Certificates included in the Pool for a Series of
Certificates will have original maturities of not more than 30 years (but may
have original maturities of substantially less than 30 years). In general, GNMA
requires that at least 90% of the original principal amount of the mortgage pool
underlying a GNMA Certificate must be mortgage loans with maturities of 20 years
or more. However, in certain circumstances GNMA Certificates may be backed by
pools of mortgage loans at least 90% of the original principal amount of which
have original maturities of at least 15 years.

     Each mortgage loan underlying a GNMA Certificate, at the time GNMA issues
its guarantee commitment, must be originated no more than 12 months prior to
such commitment date.

     The GNMA Certificates do not constitute a liability of, or evidence any
recourse against, the issuer of the GNMA Certificates, the issuer of a Series of
CitiCertificates or any affiliates thereof, and the only recourse of a
registered holder of GNMA Certificates, such as the Trustee, is to enforce the
guaranty of GNMA.

     GNMA will have approved the issuance of each of the GNMA Certificates
included in the Pool for a Series of CitiCertificates in accordance with a
guaranty agreement between GNMA and the servicer of the mortgage loans
underlying such GNMA Certificate, which is the issuer of the GNMA Certificates.
Pursuant to such agreement, such issuer is required to advance its own funds in
order to make timely payments of all amounts due on the GNMA Certificate, even
if the payments received by such issuer on the mortgage loans backing the GNMA
Certificate are less than the amounts due on such GNMA Certificate. If such
issuer is unable to make payments on a GNMA Certificate as it becomes due, it
must promptly notify GNMA and request GNMA to make such payment. Upon such
notification and request, GNMA will make such payments directly to the
registered holder of the GNMA Certificate. In the event no payment is made by
such issuer and such issuer fails to notify and request GNMA to make such
payment, the registered holder of the GNMA Certificate has recourse only against
GNMA to obtain such payment. The Trustee or its nominee, as registered holder of
the GNMA Certificates included in the Pool for a Series of CitiCertificates, is
entitled to proceed directly against GNMA under the terms of the guaranty
agreement or contract relating to such GNMA Certificates for any amounts that
are not paid when due under each GNMA Certificate.

     The GNMA Certificates included in the Pool for a Series of CitiCertificates
may have other characteristics and terms, different from those described above,
so long as such GNMA Certificates and underlying mortgage loans meet the
criteria of the rating agency or agencies rating the CitiCertificates of such
Series. Such GNMA Certificates and underlying mortgage loans will be described
in the related Prospectus Supplement. 

FHLMC

     The Federal Home Loan Mortgage Corporation ("FHLMC") is a corporate
instrumentality of the United States created pursuant to Title III of the
Emergency Home Finance Act of 1970, as amended (the "FHLMC Act"). FHLMC's common
stock is owned by the Federal Home Loan Banks. FHLMC was established primarily
for the purpose of increasing the availability of mortgage credit for the
financing of urgently needed housing. It seeks to provide an enhanced degree of
liquidity for residential mortgage investments primarily by assisting in the
development of secondary markets for conventional mortgages. The principal
activity of FHLMC currently consists 

                                      B-2
<PAGE>

of the purchase of first lien conventional residential mortgage loans or
participation interests in such mortgage loans and the resale of the mortgage
loans so purchased in the form of mortgage securities. All mortgage loans
purchased by FHLMC must meet certain standards set forth in the FHLMC Act. FHLMC
is confined to purchasing, so far as practicable, conventional mortgage loans
and participation interests therein which it deems to be of such quality, type
and class that generally meet the purchase standards imposed by private
institutional mortgage investors.

FHLMC CERTIFICATES

     Each FHLMC Certificate represents an undivided interest in a group of
mortgages ("FHLMC Certificate Group").

     Mortgage loans underlying the FHLMC Certificates included in the Pool for a
Series of CitiCertificates will consist of fixed rate mortgage loans with
original terms to maturity of between 10 and 30 years. Each such mortgage loan
must meet the applicable standards set forth in the FHLMC Act. A FHLMC
Certificate Group may include whole loans, participation interests in whole
loans and undivided interests in whole loans and/or participations comprising
another FHLMC Certificate Group.

     With respect to certain FHLMC Certificates ("Original PCs"), the period
between the first day of the month in which the Certificate is issued and the
initial payment date in respect of the Certificate is approximately 75 days.
With respect to other FHLMC Certificates ("Gold PCs"), the period between the
first day of the month in which the Certificate is issued and the initial
payment date in respect of the Certificate is approximately 45 days. In addition
to the shorter payment delay, Gold PCs differ from Original PCs in that the
record date for payments of principal and interest on a Gold PC is the last day
of the month immediately preceding the month in which the related payment date
occurs, whereas the record date for payments of principal and interest on an
Original PC is the last day of the second month preceding the month in which the
payment date occurs.

     FHLMC guarantees to each registered holder of a FHLMC Certificate the
timely payment of interest at the rate provided for by such FHLMC Certificate on
the registered holder's pro rata share of the unpaid principal balance
outstanding on the related mortgage loans, whether or not received. FHLMC also
guarantees to each registered holder of a FHLMC Certificate the ultimate
collection by such holder of all principal on the related mortgage loans,
without any offset or deduction, to the extent of such holder's pro rata share
thereof, but does not, except with respect to Gold PCs or if and to the extent
specified in the Prospectus Supplement relating to a Series of CitiCertificates
secured by Original PCs, guarantee the timely payment of scheduled principal.
Pursuant to its guarantees, FHLMC indemnifies holders of FHLMC Certificates
against any diminution in principal by reason of charges for property repairs,
maintenance and foreclosure. FHLMC may remit the amount due on account of its
guarantee of collection of principal at any time after default on an underlying
mortgage loan, but not later than (i) 30 days following foreclosure sale, (ii)
30 days following payment of the claim by any mortgage insurer, or (iii) 30 days
following the expiration of any right of redemption, whichever occurs later, but
in any event no later than one year after demand has been made upon the
mortgagor for accelerated payment of principal. In taking actions regarding the
collection of principal after default on the mortgage loans underlying FHLMC
Certificates, including the timing of demand for acceleration, FHLMC reserves
the right to exercise its servicing judgment with respect to the mortgages in
the same manner as for mortgages which it has purchased but not sold.

     FHLMC Certificates are not guaranteed by the United States or by any
Federal Home Loan Bank and do not constitute debts or obligations of the United
States or any Federal Home Loan Bank. The obligations of FHLMC under its
guarantee are obligations solely of FHLMC and are not backed by, nor entitled
to, the full faith and credit of the United States.

     Registered holders of FHLMC Certificates are entitled to receive their
monthly pro rata share of all principal payments on the underlying mortgage
loans received by FHLMC, including any scheduled principal payments, full and
partial payments of principal, and principal received by FHLMC by virtue of
condemnation, insurance or foreclosure, and repurchases of the mortgages by
FHLMC or the sellers of the mortgages. FHLMC is required to remit to each
registered FHLMC Certificateholder its pro rata share of principal payments on
the underlying mortgage loans, interest at the FHLMC Certificate rate and any
other sums (such as prepayment fees), within 60 days of the date on which such
payments are deemed to have been received by FHLMC.

     Under FHLMC's Cash Program, prior to June 1987 there was no limitation on
the amount by which interest rates on the mortgage loans underlying a FHLMC
Certificate may exceed the interest rate on the FHLMC Certificate. 

                                      B-3
<PAGE>

Under such program, FHLMC purchases groups of whole mortgage loans from sellers
at specified percentages of their unpaid principal balances, adjusted for
accrued or prepaid interest, which, when applied to the interest rate of the
mortgage loans purchased, results in the yield (expressed as a percentage)
required by FHLMC. The required yield, which includes a minimum servicing fee
retained by the servicer, is calculated using the outstanding principal balance
of the mortgage loans, an assumed term and a prepayment period as determined by
FHLMC. No loan is purchased by FHLMC at greater than 100% of the outstanding
principal balance. The range of interest rates on the mortgage loans in a FHLMC
Certificate Group under the Cash Program formed prior to June 1987 will vary
since mortgage loans are purchased and assigned to a FHLMC Certificate Group
based upon their yield to FHLMC rather than on the interest rate on the mortgage
loans. Since June 1987, the range of interest rates on the mortgage loans and
participations in a FHLMC Certificate Group comprised of 15-and 30-year fixed
rate single family mortgage loans bought by FHLMC under the Cash Program is
restricted to one percentage point. Moreover, the lowest coupon on any mortgage
loan in the FHLMC Certificate Group is greater than or equal to the annual
pass-through rate on the related FHLMC Certificate, and the highest mortgage
interest rate is not more than two percentage points above such pass-through
rate. Under FHLMC's Guarantor Program, the annual pass-through rate on a FHLMC
Certificate is established based upon the lowest interest rate on the underlying
mortgage loans, minus a minimum servicing fee and the amount of FHLMC's
management and guarantee income as agreed upon between the seller and FHLMC. For
certain FHLMC Certificate Groups formed under the Guarantor Program prior to
December 1987, the range between the lowest and highest annual interest rates on
the mortgage loans in a FHLMC Certificate Group may not exceed two percentage
points; beginning in December 1987, such range may not exceed one percentage
point.

     FHLMC Certificates duly presented for registration of transfer on or before
the last business day of a month are registered effective as of the first day of
that month. The first remittance check to a registered holder of a FHLMC
Certificate will be mailed so as to be received normally by the 15th day of the
second month following the month in which the purchaser became a registered
holder of the FHLMC Certificate. Thereafter checks will be mailed monthly to the
registered holder so as to be received normally by the 15th day of each month.
The Federal Reserve Bank of New York maintains book-entry accounts with respect
to FHLMC Certificates sold by FHLMC on or after January 2, 1985, and makes
payments of interest and principal each month to the registered holders thereof
in accordance with such holders' instructions.

     See "ADDITIONAL INFORMATION" in the body of the Prospectus for the
availability of further information respecting FHLMC and FHLMC Certificates.

     The FHLMC Certificates included in the Pool for a Series of
CitiCertificates may have other characteristics and terms, different from those
described above, so long as such FHLMC Certificates and underlying mortgage
loans meet the criteria of the rating agency or agencies rating the
CitiCertificates of such Series. Such FHLMC Certificates and underlying mortgage
loans will be described in the related Prospectus Supplement. 

FNMA

     FNMA is a federally chartered and privately owned corporation organized and
existing under the Federal National Mortgage Association Charter Act, as amended
(the "Charter Act"). FNMA was originally established in 1938 as a United States
government agency to provide supplemental liquidity to the mortgage market and
was transformed into a stockholder-owned and privately managed corporation by
legislation enacted in 1968.

     FNMA provides funds to the mortgage market primarily by purchasing home
mortgage loans from lenders, thereby replenishing their funds for additional
lending. FNMA acquires funds to purchase loans from many capital market
investors that may not ordinarily invest in mortgage loans, thereby expanding
the total amount of funds available for housing and, by operating nationwide,
FNMA helps to redistribute mortgage funds from capital-surplus to capital-short
areas. In addition, FNMA issues mortgage-backed securities primarily in exchange
for pools of mortgage loans from lenders.

     Although the Secretary of the Treasury of the United States has
discretionary authority to advance funds to FNMA, neither the United States
government nor any agency or instrumentality thereof is obligated to assume
FNMA's obligations or assist FNMA in any manner. 

FNMA CERTIFICATES

     FNMA Certificates represent fractional undivided interests in a pool of
mortgage loans formed by FNMA. Each mortgage loan must meet the applicable
standards of the FNMA purchase program. Mortgage loans comprising a 

                                      B-4
<PAGE>

pool are either provided by FNMA from its own portfolio or purchased pursuant to
the criteria of the FNMA purchase program.

     Mortgage loans underlying FNMA Certificates included in the Pool for a
Series of CitiCertificates will consist of conventional mortgage loans, FHA
Loans or VA Loans. The original maturities of substantially all of the
conventional, level payment mortgage loans underlying a FNMA Certificate are
expected to be between either 8 and 15 years or 20 and 30 years. The original
maturities of substantially all of the level payment FHA Loans or VA Loans are
expected to be 30 years.

     Mortgage loans underlying a FNMA Certificate may have annual interest rates
that vary by as much as two percentage points from each other. The rate of
interest payable on a FNMA Certificate is equal to the lowest interest rate of
any mortgage loan in the related pool, less a specified minimum annual
percentage representing servicing compensation and FNMA's guaranty fee. Under a
regular servicing option (pursuant to which the mortgagee or other servicer
assumes the entire risk of foreclosure losses), the annual interest rates on the
mortgage loan underlying a FNMA Certificate will be between 50 basis points and
250 basis points greater than the annual interest rate for the FNMA
Certificates; and under a special servicing option (pursuant to which FNMA
assumes the entire risk for foreclosure losses), the annual interest rates on
the mortgage loans underlying a FNMA Certificate will generally be between 55
basis points and 255 basis points greater than the annual FNMA Certificate
interest rate.

     FNMA guarantees to each registered holder of a FNMA Certificate that it
will distribute amounts representing scheduled principal and interest (at the
rate provided for by such FNMA Certificate) on the mortgage loans in the pool
represented by such FNMA Certificate, whether or not received, and the full
principal amount of any foreclosed or other finally liquidated mortgage loan,
whether or not such principal amount is actually recovered. The obligations of
FNMA under its guarantees are obligations solely of FNMA and are not backed by,
nor entitled to, the full faith and credit of the United States. Although the
Secretary of the Treasury of the United States has discretionary authority to
lend FNMA up to $2.25 billion outstanding at any time, neither the United States
nor any agency thereof is obligated to finance FNMA's operations or to assist
FNMA in any other manner. If FNMA were unable to satisfy its obligations,
distributions to holders of FNMA Certificates would consist solely of payments
and other recoveries on the underlying mortgage loans and, accordingly, monthly
distributions to holders of FNMA Certificates would be affected by delinquent
payments and defaults on such mortgage loans.

     Unless otherwise specified in the Prospectus Supplement relating to a
Series of CitiCertificates, FNMA Certificates evidencing interests in pools of
mortgage loans formed on or after May 1, 1985 are available in book-entry form
only and will not be convertible to definitive form. Distributions of principal
and interest on each FNMA Certificate will be made by FNMA on the 25th day of
each month to the persons in whose name the FNMA Certificate is entered on the
books of the Federal Reserve Bank (or registered in the FNMA Certificate
register in the case of fully registered FNMA Certificates) as of the close of
business on the last day of the preceding month. With respect to FNMA
Certificates issued in book-entry form, distributions thereon will be made by
wire, and with respect to fully registered FNMA Certificates, distributions
thereon will be made by check.

     See "ADDITIONAL INFORMATION" in the body of the Prospectus for the
availability of further information respecting FNMA and FNMA Certificates.

     The FNMA Certificates included in the Pool for a Series of CitiCertificates
may have other characteristics and terms, different from those described above,
so long as such FNMA Certificates and underlying mortgage loans meet the
criteria of the rating agency or agencies rating the CitiCertificates of such
Series. Such FNMA Certificates and underlying mortgage loans will be described
in the related Prospectus Supplement.
