                             ---------------------

    The Offered  CitiCertificates are  being  offered by  Prudential  Securities
Incorporated (the "Underwriter") 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
97.531101%   of   the  aggregate   Initial  Stated   Amount   of  the   Class  A
CitiCertificates and 90.166666667% of the aggregate Initial Stated Amount of the
Offered Class B CitiCertificates, plus accrued interest at the rate of 6.25% per
annum from March  1, 1994  (the "Cut-Off  Date"), before  deduction of  expenses
payable  by  the  Issuer,  subject  to a  limited  adjustment  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 Underwriter, to prior sale and  to the Underwriter's right to reject  any
order  in whole  or in  part. It  is expected  that on  or about  March 29, 1994
delivery will be  made through the  facilities of The  Depository Trust  Company
("DTC"),  in the case of the Class  A CitiCertificates, and in definitive, fully
registered form, in the case of the Offered Class B CitiCertificates.

           THE DATE OF THIS PROSPECTUS SUPPLEMENT IS MARCH 24, 1994.

(CONTINUED FROM PREVIOUS PAGE)

property of  the  Trust ranging  from  91.75% to  93.75%,  the Offered  Class  B
CitiCertificates  will  initially  evidence  an  undivided  beneficial ownership
interest in  the property  of the  Trust ranging  from 5.50%  to 7.50%  and  the
Unoffered  Class  B  CitiCertificates  will  evidence  the  remaining  undivided
interest therein. Only  the Class  A CitiCertificates  and the  Offered Class  B
CitiCertificates (the "Offered CitiCertificates") are offered hereby.

    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") or  originated
by  Citibank, N.A. ("Citibank," and together with CMI, the "Originators") as the
case may be,  with an aggregate  Adjusted Balance  as of the  Cut-Off Date  (the
"Initial Mortgage Loan Balance") equal to approximately $258,891,390, 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").

    Interest on the Offered CitiCertificates will be distributed on the 25th day
of   each   month,   commencing  (except   with   respect  to   the   Class  A-7
CitiCertificates) in April 1994 (or, if such  day is not a business day, on  the
next  succeeding  business day)  (each, a  "Distribution  Date"). The  Class A-7
CitiCertificates are Accrual CitiCertificates. The  Class A-2, Class A-3,  Class
A-4,  Class A-5, Class A-6 and Class A-7 CitiCertificates are sometimes referred
to collectively as the  "Accretion Directed CitiCertificates." Distributions  of
interest on the Class A-7 CitiCertificates will commence on the earlier to occur
of  (i)  the Distribution  Date  on which  the Stated  Amount  of the  Class A-6
CitiCertificates has been reduced to  zero and (ii) the Subordination  Depletion
Date.  Prior  to the  commencement of  interest distributions  on the  Class A-7
CitiCertificates, interest will accrue  thereon and the  amounts so accrued  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
Amounts  of the  Accretion Directed  CitiCertificates as  described herein under
"SUMMARY OF PROSPECTUS AND PROSPECTUS SUPPLEMENT--Distributions in Reduction  of
Stated  Amount of  the Offered  CitiCertificates." Interest  will accrue  on the
CitiCertificates from the first through the last day of the month preceding  the
month  of  such  Distribution  Date.  The  rights  of  holders  of  the  Class B
CitiCertificates to receive  distributions of interest  will be subordinated  to
the  rights of holders of the  Class A 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 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 Offered Class B CitiCertificates will be made only after the Class
A CitiCertificates have received  all distributions to  which they are  entitled
and  the Offered Class  B 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 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.  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, 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, 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-7 CITICERTIFICATES ARE A COMPANION
CLASS TO  THE  TAC CERTIFICATES,  THE  WEIGHTED AVERAGE  LIFE  OF SUCH  CLASS  A
SUBCLASS  WILL  BE PARTICULARLY  SENSITIVE  TO THE  RATE  OF PREPAYMENTS  ON THE
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.

    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 CITICERTIFICATES, IN THE EVENT THAT THE STATED  AMOUNT
OF  THE  UNOFFERED  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 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 Offered Class B CitiCertificates may not be acquired by or on behalf of,
or with the assets of, any employee benefit plan, trust or account including  an
individual retirement account, that is subject to the Employee Retirement Income
Security  Act of 1974, as amended  ("ERISA"), or the corresponding provisions of
the Internal Revenue  Code of 1986,  as amended (the  "Code") or a  governmental
plan  subject to any federal, state or local law which is, to a material extent,
similar to  the foregoing  provisions of  ERISA  or the  Code, except  upon  the
delivery  of an opinion of counsel or as otherwise provided herein. See "CERTAIN
INVESTMENT CONSIDERATIONS FOR PURCHASERS OF OFFERED CLASS B
CITICERTIFICATES--Restrictions on Transfer" herein.

    The closing of the sale of the Offered CitiCertificates is conditioned  upon
the  closing of the  sale of the Unoffered  Class B CitiCertificates. Prudential
Securities Incorporated is committed  to purchase all of  the Unoffered Class  B
CitiCertificates if any Offered CitiCertificates are purchased.

    There is currently no secondary market for the Offered CitiCertificates. The
Underwriter   anticipates   making   a   secondary   market   in   the   Offered
CitiCertificates 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 Offered CitiCertificates with  liquidity of investment  or will continue  for
the life of the Offered CitiCertificates.

    The  Class A  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  "--Definitive  Certificates"  herein.  The  Offered  Class B
CitiCertificates will be issued in definitive, fully registered form.
                             ---------------------

    IN CONNECTION WITH THIS OFFERING,  THE UNDERWRITER MAY OVER-ALLOT OR  EFFECT
TRANSACTIONS  WHICH  STABILIZE  OR  MAINTAIN THE  MARKET  PRICE  OF  THE OFFERED
CITICERTIFICATES AT A LEVEL ABOVE THAT WHICH MIGHT OTHERWISE PREVAIL IN THE OPEN
MARKET. SUCH STABILIZING, IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME.

                                       Initial Stated Amounts set forth on the cover page hereof.
                                       Each  Offered  CitiCertificate  represents  an   undivided
                                       beneficial  ownership interest in  the Trust created under
                                       the Pooling Agreement, the property of which will  consist
                                       of  a pool of  assets comprised primarily  of the Mortgage
                                       Loans conveyed  to  the  Issuer  by  the  Originators  and
                                       simultaneously  conveyed to such Trust  by the Issuer. The
                                       rights of holders of the Offered Class B  CitiCertificates
                                       to  receive  distributions  will  be  subordinated  to the
                                       rights of holders of the  Class A CitiCertificates to  the
                                       extent described herein.
                                     Each  Class A CitiCertificate will  qualify at issuance as a
                                       "mortgage related  security"  within the  meaning  of  the
                                       Secondary   Mortgage  Market   Enhancement  Act   of  1984
                                       ("SMMEA") and will retain such qualification so long as it
                                       is rated in one of the two highest rating categories by at

                                       organization.  The Offered  Class B  CitiCertificates will
                                       not constitute  "mortgage related  securities" within  the
                                       meaning   of  SMMEA.   See  "LEGAL   INVESTMENT"  in  this

                                       Pass-Through  Certificates,  Series  1994-5,  include  the
                                       Class   B-2  CitiCertificates  (the   "Unoffered  Class  B

                                       retained by the Originators. Neither the Unoffered Class B

                                       offered by this Prospectus Supplement and the related Pro-

                                       the Offered CitiCertificates. The issuance and sale of the

                                       Initial  Mortgage  Loan  Balance.  The  aggregate  Initial
                                       Stated  Amount of  the Unoffered  Class B CitiCertificates
                                       will correspond to the remaining percentage of the Initial
                                       Mortgage Loan Balance. The  Initial Mortgage Loan  Balance

                                       to zero, the Offered Class B Stated Amount may be  subject
                                       to  a  further reduction  such  that the  Offered  Class B
                                       Stated Amount will equal  the difference between the  Pool
                                       Adjusted  Balance and the  Class A Stated  Amount. On each

                                       distributions to  the  extent  described  herein  and  the

                                       resulting from the liquidation of defaulted Mortgage Loans
                                       or the bankruptcy of Mortgagors prior to the allocation of
                                       such  losses   to  holders   of   the  Offered   Class   B

                                      the Prospectus.
                                    In the event that on any Distribution Date the Offered Class
                                      B Subordination Percentage is less than the Offered  Class
                                      B  Subordination Percentage on the  Closing Date, then the
                                      Unoffered 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 Offered Class B CitiCertificates. The "Offered Class B
                                      Subordination  Percentage" is  the percentage  obtained by
                                      dividing the
                                    Stated Amount of the  Unoffered Class B CitiCertificates  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  any
                                      allocation of losses  on such date).  The Offered Class  B
                                      Subordination  Percentage on the  Closing Date is expected
                                      to be between 0.55% and 0.95%.
                                    On any  Distribution  Date  on or  after  the  Subordination
                                      Depletion   Date,  funds  available  for  distribution  in
                                      reduction of Stated Amount of the Class A CitiCertificates
                                      will be  distributed pro  rata to  each Class  A  Subclass
                                      notwithstanding  the  priorities  described  in  the third
                                      paragraph under this heading. Under the circumstances  de-
                                      scribed  in this  paragraph, the amount  allocated to each
                                      Class A  Subclass  will  be  distributed  pro  rata  among
                                      holders of CitiCertificates of such Class A Subclass.
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" 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

PREPAYMENT AND YIELD
  CONSIDERATIONS..................  The yield  to maturity  and weighted  average lives  of  the
                                    Class   A   CitiCertificates   and  the   Offered   Class  B
                                      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
                                      and Offered Class B  CitiCertificates, and the timing  and
                                      extent  of losses,  if any, allocated  to the  Class A and
                                      Offered Class  B  CitiCertificates. No  representation  is
                                      made  as to whether the Mortgage  Loans will prepay at any
                                      particular rate. See

THE MORTGAGE LOANS
  A. GENERAL......................  The Mortgage  Loans will  have mortgage  rates ranging  from
                                    6.50%  to 12.375%  per annum.  The initial  weighted average
                                      mortgage rate of the Mortgage  Loans is expected to be  at
                                      least 7.18% but no more than 7.58% per annum. The weighted
                                      average  remaining term to stated maturity of the Mortgage
                                      Loans will be  at least 340  months but no  more than  346
                                      months.
                                    The  Mortgage Loans will consist of 20-to 30-year fixed rate
                                      conventional mortgage loans originated or acquired by  CMI
                                      or  originated by Citibank,  as the case  may be. Mortgage
                                      Loans acquired by CMI include Mortgage Loans originated or
                                      acquired by CFSB.  See "DESCRIPTION  OF THE  POOL AND  THE
                                      MORTGAGED  PROPERTIES" in  this Prospectus  Supplement and
                                      "THE  POOLS--Mortgage   Loans"  in   the  Prospectus   for
                                      additional information concerning the Mortgage Loans.
  B. CERTIFICATE ACCOUNT..........  All  payments  received in  respect  of the  Mortgage Loans,
                                    beginning with the April 1994 distribution, will be remitted
                                      directly  to  a  certificate  account  (the   "Certificate
                                      Account")  to  be  established  with  the  Trustee  on the
                                      Closing Date  as part  of the  assets of  the REMIC.  Such
                                      payments  will be available for distributions in reduction
                                      of  Stated   Amount   of,   and  of   interest   on,   the
                                      CitiCertificates  on the  Distribution Date  on which such
                                      funds are remitted to the Certificate Account.
ALLOCATION OF LOSSES..............  Shortfalls in receipts of interest on the Mortgage 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
                                      until  the  Subordination  Depletion Date.  Prior  to such
                                      time, such Realized Losses will be allocated first to  the
                                      Unoffered    Class    B    CitiCertificates    until   the

                                      has been reduced to zero and second to the Offered Class B
                                      CitiCertificates  until the Stated Amount thereof has been
                                      reduced to zero.
                                    The principal  portion of  any Excess  Special Hazard  Loss,
                                      Excess  Fraud  Loss  or  Excess  Bankruptcy  Loss  will be
                                      allocated between the Class A and Class B CitiCertificates
                                      pro  rata  based  on  their  respective  aggregate  Stated
                                      Amounts,  and among  the Class  A and  Class B Subclasses,
                                      respectively, as to the amounts  allocated to the Class  A
                                      and  Class  B  CitiCertificates pro  rata  based  on, with
                                      respect to each  Class A  and Class B  Subclass, the  then
                                      current  Stated Amount of such Class A or Class B Subclass
                                      or, in the  case of  the Class  A-7 CitiCertificates,  the
                                      Initial  Stated Amount  thereof, if  lower, and  among the
                                      outstanding Class A and Class B CitiCertificates pro  rata
                                      within  each Class A or Class  B Subclass, as the case may
                                      be. Any such allocation  will be accomplished by  reducing
                                      the outstanding Stated Amount of each Class A Subclass and
                                      each  Class B Subclass and  the outstanding Stated Amounts
                                      of each  Class  A  CitiCertificate  within  each  Class  A
                                      Subclass  and  each  Class B  CitiCertificate  within each
                                      Class B Subclass by the appropriate pro rata share of  any
                                      such principal losses.
                                    On  each  Distribution  Date  that occurs  on  or  after the
                                      Subordination  Depletion   Date,   holders  of   Class   A
                                      CitiCertificates  will generally  receive their respective
                                      pro rata  share of  net Liquidation  Proceeds realized  on
                                      Liquidated  Loans (after reimbursement to the Servicer and
                                      the Trustee of 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 ad-
                                      vances. On each  Distribution Date, the  Servicer and  the
                                      Trustee  will  be  entitled  to  withdraw  funds  from the
                                      Certificate  Account   (a)   in   reimbursement   of   all
                                      unreimbursed   advances  deemed  by  the  Servicer  to  be
                                      nonrecoverable and  (b)  in  reimbursement  of  all  other
                                      unreimbursed  advances 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  distributions
                                    reducing the Stated Amount of such CitiCertificates to  zero
                                      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.  Any such  final  distribution  in
                                      reduction   of   Stated   Amount  with   respect   to  the
                                      CitiCertificates  will  be  in  an  amount  equal  to  the

RECORD DATE.......................  The Record Date for each Distribution Date will be the close
                                    of business on the last day of the month preceding the month

CERTAIN FEDERAL INCOME TAX
  CONSEQUENCES....................  The  Trust will  elect to be  treated and will  qualify as a
                                    REMIC for  purposes of  Sections 860A  through 860G  of  the
                                      Internal  Revenue Code  of 1986, as  amended (the "Code").
                                      The Offered CitiCertificates will be designated as regular
                                      interests in the  REMIC and generally  will be treated  as
                                      newly  originated debt instruments  for federal income tax
                                      purposes. Beneficial Owners  (or holders, in  the case  of
                                      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
                                      CitiCertificates  will  be  issued  with  original   issue
                                      discount   in  an  amount  equal  to  the  excess  of  all
                                      distributions of principal  and interest (whether  current
                                      or  accrued) expected  to be  received thereon  over their
                                      issue  price   (including   accrued   interest).   It   is
                                      anticipated  that  the Class  A-2,  Class A-3,  Class A-4,
                                      Class A-5 and Class  A-6 CitiCertificates and the  Offered
                                      Class  B  CitiCertificates  will be  issued  with original
                                      issue discount in an amount  equal to the excess of  their
                                      Initial  Stated Amounts (plus accrued interest) over their
                                      respective issue prices  (including accrued interest).  It
                                      is further anticipated that the Class A-1 CitiCertificates
                                      will  be  issued  at  a  premium  for  federal  income tax
                                      purposes.
                                    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, and  that  may be  used  by the
                                      Beneficial Owner (or  holder, in  the case  of an  Offered
                                      Class  B CitiCertificate) of an Offered CitiCertificate to
                                      amortize premium, is  350% of the  Prepayment Model's  (as
                                      defined herein) assumed prepayment rates. See "DESCRIPTION
                                      OF THE OFFERED CITICERTIFICATES--Weighted Average Lives of

                                      Supplement. No representation  is made as  to the rate  at
                                      which the Mortgage Loans will prepay.
                                    The  Offered CitiCertificates will be treated as "qualifying
                                      real property loans" for mutual savings banks and domestic
                                      building and loan  associations, "regular  interests in  a

                                      review the discussion  in this  Prospectus Supplement  and
                                      the  Prospectus under the  caption "ERISA CONSIDERATIONS,"
                                      especially the  discussion  thereunder  of  the  potential
                                      application of PTE 83-1 (as defined therein).
                                    On  June  6, 1990,  the Department  of  Labor issued  to the
                                      Underwriter Prohibited  Transaction Exemption  90-32  (the
                                      "Exemption"),  which Exemption  generally was  intended to
                                      apply to  the  purchase  and holding  by  ERISA  Plans  of
                                      securities  such  as the  Class A  CitiCertificates, which
                                      represent beneficial interests in pass-through trusts that
                                      meet the  requirements  of the  Exemption.  The  Exemption
                                      should apply to the acquisition, holding and resale of the
                                      Class  A CitiCertificates by an  ERISA Plan, provided that
                                      specified  conditions  (certain  of  which  are  described
                                      herein,  including the condition that the ERISA Plan be an
                                      "accredited investor"  (as defined  in Rule  501(a)(1)  of

                                      (the "Commission") under the Securities Act of 1933))  are
                                      met.   See  "ERISA  CONSIDERATIONS"   in  this  Prospectus
                                      Supplement.
                                    Neither the Exemption nor PTE 83-1 apply to the purchase  or
                                      holding   of  securities  such  as  the  Offered  Class  B
                                      CitiCertificates   because   such   CitiCertificates   are
                                      subordinated to the Class A CitiCertificates. Accordingly,
                                      Plans    may   not   purchase    the   Offered   Class   B

CERTIFICATE RATINGS...............  It   is  a  condition   to  the  issuance   of  the  Offered
                                    CitiCertificates that the Class A CitiCertificates be  rated
                                      "AAA" by Standard & Poor's Ratings Group ("S&P") and "Aaa"
                                      by  Moody's Investors  Service, Inc.  ("Moody's") and that
                                      the Offered  Class B  CitiCertificates be  rated at  least
                                      "Baa3" by Moody's. 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.   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

                            DESCRIPTION OF THE POOL
                          AND THE MORTGAGED PROPERTIES

    The Pool to be evidenced by the CitiCertificates will include Mortgage Loans
evidenced by mortgage notes with an aggregate Adjusted Balance as of the Cut-Off
Date of approximately $258,891,390. This amount is subject to a permitted upward
or downward variance of up to 5.0%.

    The "Adjusted Balance" of any Mortgage Loan as of the first day of any month
is  the scheduled principal balance thereof as  of the close of business on such
day (whether or  not any scheduled  payments have been  received and before  any
adjustment  to the related amortization schedule  by reason of bankruptcy (other
than a  Deficient Valuation)),  less  any 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).

    A detailed description  (the "Detailed Description")  of the Mortgage  Loans
will  be available at the time of issuance of the CitiCertificates. The Detailed
Description will specify  the Initial Mortgage  Loan Balance as  of the  Cut-Off
Date  and  will  also  set forth  tables  reflecting  the  following information
regarding the Mortgage Loans:  years of origination, types  of dwellings on  the
underlying  properties, sizes of Mortgage  Loans, distribution of Mortgage Loans
by  loan-to-value  ratios,  mortgage  rates  and  geographical  distribution  of
Mortgage  Loans by state. The Detailed Description will also specify the Special
Hazard Loss  Amount, Fraud  Loss Amount  and Bankruptcy  Loss Amount  as of  the
Cut-Off   Date,  the   aggregate  Initial   Stated  Amounts   of  the   Class  A
CitiCertificates, the Offered Class B CitiCertificates and the Unoffered Class B
CitiCertificates, the Class B CitiCertificate Percentage and the Offered Class B
Subordination Percentage as of  the Cut-Off Date.  The information contained  in
the Detailed Description will be set forth in a report on Form 8-K which will be
filed   with   the  Commission   within  15   days  of   the  issuance   of  the
CitiCertificates.

    The following paragraphs set  forth detailed information  as of the  Cut-Off
Date  with respect  to the  Mortgage Loans expected  to be  in the  Pool. To the
extent that the Mortgage  Loans differ from  the descriptions contained  herein,
immaterial variances in such information may result.

will be at least 7.18% but no more than 7.58% per annum. The Mortgage Loans will
have Note  Rates of  at least  6.50% but  no more  than 12.375%  per annum.  The
weighted  average remaining term to stated maturity  of the Mortgage Loans as of
the Cut-Off Date will be at least 340 months but no longer than 346 months.  All
of  the Mortgage Loans will have original maturities  of 20 to 30 years. None of
the Mortgage Loans will have been originated prior to September 1, 1973 or after
March 1, 1994. None of the Mortgage  Loans will have a scheduled maturity  later
than March 1, 2024.

    The  Mortgage Loans will have the following additional characteristics as of
the Cut-Off Date (expressed as a percentage of the aggregate Adjusted Balance of
the Mortgage Loans having such characteristics relative to the Initial  Mortgage
Loan Balance):

    At  least 85% of the Mortgage Loans  will be Mortgage Loans originated using
loan underwriting policies effective  April 1, 1991  which require, among  other
things,  proof  of  income  and  liquid  assets  and  telephone  verification of
employment.  See   "LOAN  UNDERWRITING   POLICIES  AND   LOSS  AND   DELINQUENCY
CONSIDERATIONS" in the Prospectus.

    At  least 35% of  the Mortgage Loans  will be Mortgage  Loans each having an
Adjusted Balance of less than $250,000.

    At least 90% of  the Mortgage Loans  will be Mortgage  Loans each having  an
Adjusted Balance of less than $500,000.

    No more than 10% of the Mortgage Loans will be Mortgage Loans each having an
Adjusted Balance of at least $500,000 but less than $1,000,000.

    No more than 20% of the Mortgage Loans will have had loan-to-value ratios at
origination in excess of 80%; no more than 1% will have had loan-to-value ratios
at  origination in excess  of 90% and none  of the Mortgage  Loans will have had
loan-to-value ratios  at origination  in  excess of  95%. The  weighted  average

                                      S-18
<PAGE>
loan-to-value  ratio at origination of the Mortgage Loans as of the Cut-Off Date
will be  no  more  than 76%.  For  more  information on  Mortgage  Loans  having
loan-to-value  ratios  at origination  in excess  of 80%,  see "APPENDIX  A: THE
MORTGAGE LOANS AND  CITIMORTGAGE CERTIFICATES--The  Mortgage Loans--General"  in
the Prospectus.

    No  more than  15% of  the Mortgage Loans  were originated  between 1986 and
1992.

    At least 95% of the Mortgage Loans will be secured by one-family dwellings.

    No more than  15% of  the Mortgage Loans  will be  secured by  condominiums,
shares issued by cooperative housing corporations, townhouses and rowhouses.

    No  more  than  5%  of  the Mortgage  Loans  will  be  secured  by Mortgaged
Properties located in any one zip code.

    No more than  25%, 20%  and 15%  of the Mortgage  Loans will  be secured  by
Mortgaged Properties located in California, New York and Virginia, respectively.
No  more than 10% of the Mortgage  Loans will be secured by Mortgaged Properties
located in any other state.

    A portion of the Mortgaged Properties  located in California are located  in
areas  which were affected by the  earthquake on January 17, 1994. Substantially
all of such Mortgaged Properties have been checked for exterior damage. Based on
such efforts  to  determine  the  condition of  the  Mortgaged  Properties,  CMI
believes  that Mortgaged  Properties representing  less than  1% of  the Initial
Mortgage Loan Balance warrant further  review. The Pooling Agreement contains  a
representation by CMI that each Mortgaged Property is in good repair and free of
material  damage as of the Closing Date. If that representation is determined to
be inaccurate in respect of a Mortgage Loan, and such inaccuracy has a  material
and  adverse effect on the interests  of the Certificateholders in such Mortgage
Loan, CMI is obligated  to repurchase or substitute  a comparable mortgage  loan
for  such Mortgage Loan. If any such repurchase is made, such repurchase will be
treated as a  prepayment of  the related  Mortgage Loan  and, consequently,  may
affect the yields and the weighted average lives of the CitiCertificates.

    At  least 90% of the  Mortgage Loans will be determined  by the Issuer to be
secured by a Mortgage on the primary residence of the borrower. No more than  5%
of  the Mortgage Loans will be secured  by investment properties. See " APPENDIX
A: THE  MORTGAGE  LOANS  AND  CITIMORTGAGE  CERTIFICATES--The  Mortgage  Loans--
General" in the Prospectus.

                       CERTAIN INVESTMENT CONSIDERATIONS
               FOR PURCHASERS OF OFFERED CLASS B CITICERTIFICATES

    Investors  should consider, among other  things, the factors discussed below
in connection with any purchase of Offered Class B CitiCertificates.

SUBORDINATION

    The Offered Class B CitiCertificates  are subordinated in right of  payments
to  the Class  A CitiCertificates  as described herein.  Holders of  the Class A
CitiCertificates will  have a  preferential right  to receive  out of  the  Pool
Distribution  Amount for  a Distribution Date,  prior to  any distribution being
made on  such date  in respect  of  the Offered  Class B  CitiCertificates,  all
distributions  due on the Class  A CitiCertificates. Shortfalls in distributions
in reduction of Stated  Amount of the Class  A CitiCertificates will be  applied
first to the Stated Amount of the Unoffered Class B CitiCertificates and then to
the  Offered Class B CitiCertificates before  being applied to the Stated Amount
of  the   Class   A   CitiCertificates.  See   "DESCRIPTION   OF   THE   OFFERED
CITICERTIFICATES" in this Prospectus Supplement.

DELINQUENCIES AND ADVANCES

    The  Servicer may,  but is  not obligated  to, make  advances in  respect of
delinquent scheduled payments of principal of or interest on the Mortgage Loans.
The Servicer intends to make advances to the extent the Servicer determines  the
amounts   of  such  advances  will  be  recoverable  from  future  payments  and
collections on the related 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 any such
advance. The Trustee (in such

                                      S-19
<PAGE>
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. The  Offered  Class B  CitiCertificates will  have  the
benefit  of all such advances.  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  and therefore  holders of the  Offered Class B  CitiCertificates may not
receive any payment for certain Distribution Dates.

ALLOCATION OF LOAN LOSSES

    LIQUIDATED LOANS:   Realized Losses  on the Mortgage  Loans as  a result  of
losses  realized on  Liquidated Loans will  be allocated first  to the Unoffered
Class B CitiCertificates up  to the Stated Amount  thereof and accrued  interest
thereon and then to the Offered Class B CitiCertificates up to the Stated Amount
thereof  and accrued interest  thereon. Holders of  the Class A CitiCertificates
will be entitled to receive the  Class A Prepayment Percentage of the  principal
portion of net liquidation proceeds.

    SPECIAL  HAZARD  LOSSES:   Until the  Special  Hazard Termination  Date, all
Special Hazard Losses will reduce the Stated Amount of, and accrued interest on,
the Class  B  CitiCertificates,  in the  order  of  priority set  forth  in  the
preceding paragraph. Holders of the Class A 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  principal portion  of the related  net liquidation  proceeds.
After   the  Special  Hazard   Termination  Date,  the  Class   A  and  Class  B
CitiCertificateholders will bear their pro  rata share of the principal  portion
of Excess Special Hazard Losses. Excess Special Hazard Losses are Special Hazard
Losses  in excess  of the  Special Hazard Loss  Amount, which  will initially be
equal  to  approximately  1.00%  of  the  Initial  Mortgage  Loan  Balance.  See
"DESCRIPTION  OF  THE OFFERED  CITICERTIFICATES-- Subordination  of the  Class B
CitiCertificates--Allocation of Losses" in this Prospectus Supplement.

    FRAUD LOSSES:  Until the Fraud  Coverage Termination Date, all Fraud  Losses
will  reduce  the  Stated  Amount  of, and  accrued  interest  on,  the  Class B
CitiCertificates, in the  order of priority  set forth in  the second  preceding
paragraph.  Holders of the Class A 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
principal portion  of the  related  net liquidation  proceeds. After  the  Fraud
Coverage  Termination Date, the Class A  and Class B CitiCertificateholders will
bear their  pro rata  share of  the principal  portion of  Excess Fraud  Losses.
Excess  Fraud Losses are Fraud Losses in  excess of the Fraud Loss Amount, which
will initially be  equal to  approximately 2.00%  of the  Initial Mortgage  Loan
Balance.  See "DESCRIPTION OF THE OFFERED CITICERTIFICATES--Subordination of the
Class B CitiCertificates--Allocation of Losses" in this Prospectus Supplement.

    BANKRUPTCY LOSSES:   Until  the Bankruptcy  Coverage Termination  Date,  all
Bankruptcy Losses will reduce the Stated Amount of, and accrued interest on, the
Class  B  CitiCertificates, in  the order  of  priority set  forth in  the third
preceding paragraph. On each Distribution Date occurring prior to the Bankruptcy
Coverage Termination Date,  the Stated  Amount of the  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  principal
portion of such Bankruptcy Loss. After the Bankruptcy Coverage Termination Date,
the Class A and Class B CitiCertificateholders will bear their pro rata share of
the  principal portion of Excess Bankruptcy Losses. Excess Bankruptcy Losses are
Bankruptcy Losses in excess of the Bankruptcy Loss Amount, which will  initially
be  equal  to approximately  0.04%  of the  Initial  Mortgage Loan  Balance. See
"DESCRIPTION OF  THE  OFFERED  CITICERTIFICATES--Subordination of  the  Class  B
CitiCertificates--Allocation of Losses" in this Prospectus Supplement.

    The  exact amounts  of Special  Hazard Losses,  Fraud Losses  and Bankruptcy
Losses to be allocated to the Class B CitiCertificates (in each case only  prior
to  the related termination date)  will be those amounts  required by 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 proportionately between
the CitiCertificates and the Residual Certificates, based on (in the case of the
CitiCertificates) the interest accrued thereon and (in the case of the  Residual
Certificates)

                                      S-20
<PAGE>
the  excess of the  interest accrued on the  Mortgage Loans over  the sum of the
Servicing Fee and  the interest accrued  on the CitiCertificates,  and pro  rata
between  the Class A and Class B  CitiCertificates based on the interest accrued
on each such Class.

EFFECT OF LOSSES AND OTHER SHORTFALLS

    The ultimate payment to holders of  the 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  and then  to  the
Offered Class B CitiCertificates until the Subordination Depletion Date.

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

    Also, on or prior to the Subordination Depletion Date, because the  Residual
Certificates  are entitled to receive from  funds deposited into the Certificate
Account before  such funds  are distributed  to the  CitiCertificateholders  the
portion of interest whether or not received (net of Servicing Fee and Prepayment
Interest  Shortfalls  allocated to  the Residual  Certificates) on  the Mortgage
Loans that is in excess of 6.25% per annum on the aggregate Stated Amount of the
CitiCertificates, any shortfall in interest paid on a Mortgage Loan which is not
advanced by  the  Servicer  or  the  Trustee  will  result  in  a  shortfall  in
distributions  to the Class  B CitiCertificates and, depending  on the extent of
such shortfall  of interest,  may  result in  a  shortfall in  distributions  to
holders of the Offered Class B CitiCertificates.

RESTRICTIONS ON TRANSFER

    Under  current  law,  the  purchase  and  holding  of  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.
Transfer of the Offered Class B  CitiCertificates will not be registered  unless
the  transferee  (i)  executes a  representation  letter in  form  and substance
satisfactory to the Trustee stating 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 (ii) provides an opinion of counsel in form and substance satisfactory to the
Trustee that the purchase or holding of 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.

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 Offered Class B CitiCertificates.
The Issuer makes no representations or warranties concerning whether the Offered
Class B CitiCertificates are legal investments  under any federal or state  law,
regulation,  rule or order of any court. An Offered Class B CitiCertificate does
not constitute  a  "mortgage related  security"  within the  meaning  of  SMMEA.
Prospective  investors are advised to consult  their counsel as to qualification
of 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  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 CitiCertificate at the time of
issuance will qualify  as a "mortgage  related security" within  the meaning  of
SMMEA and will retain such qualification so

                                      S-21
<PAGE>
long  as it is rated in one of the two highest rating categories by at least one
nationally recognized  statistical  rating  organization.  An  Offered  Class  B
CitiCertificate  will not  qualify as a  "mortgage related  security" within the
meaning of SMMEA.

    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 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 accrue on 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 will equal the interest accrued for an Interest Accrual  Period
at  the rate of  6.25% per annum on  the Class A Subclass  Stated Amount of such
Class A  Subclass, 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  sum of the Class A
Subclass Interest Amounts  for a particular  Distribution Date is  the "Class  A
Interest Amount."

    The   amount  of  interest   that  will  accrue  on   the  Offered  Class  B
CitiCertificates and the Unoffered Class B CitiCertificates during each Interest
Accrual Period is referred  to herein as the  "Offered Class B Interest  Amount"
and  the "Unoffered Class B Interest  Amount," respectively. The Offered Class B
Interest Amount will equal the interest  accrued for an Interest Accrual  Period
at  the rate  of 6.25% per  annum on  the Stated Amount  of the  Offered Class B
CitiCertificates and  the  Unoffered Class  B  Interest Amount  will  equal  the
interest  accrued for an Interest Accrual Period at the rate of 6.25% per annum,
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  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  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 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-7
CitiCertificates,   the  Accretion  Distribution   Amount,  as  described  under
"--Distributions in Reduction of Stated Amount," below, previously added to  the
Stated Amount of the Class A-7 CitiCertificates, 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 principal portion of Excess Special Hazard Losses,  Excess
Fraud  Losses and  Excess Bankruptcy Losses  previously allocated  to holders of
Class A CitiCertificates in the manner described below under "--Subordination of
the Class  B CitiCertificates--Allocation  of Losses."  After the  Subordination
Depletion  Date, the Class A Subclass Stated Amount of a Class A Subclass 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 as
of such Distribution  Date without  regard to this  provision and  (b) the  Pool
Adjusted  Balance for the  preceding Distribution Date.  Any pro rata allocation
among the Class A Subclasses described in this paragraph will be made among  the
Class  A Subclasses  on the  basis of  their then  outstanding Class  A Subclass
Stated Amounts or,  in the case  of the Class  A-7 CitiCertificates the  Initial
Stated  Amount, if lower,  as of the  preceding Distribution Date.  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 "Offered Class B Stated Amount" as of any Distribution Date will be  the
lesser  of (a) the Initial Stated Amount of the Offered Class B CitiCertificates
less (i) all amounts  previously distributed to holders  of the Offered Class  B
CitiCertificates  in  reduction  of  the  Stated  Amount  thereof  and  (ii) the
principal portion  of Excess  Special  Hazard Losses,  Excess Fraud  Losses  and
Excess  Bankruptcy Losses previously allocated to holders of the Offered Class B
CitiCertificates in the  manner described  below under  "--Subordination of  the

                                      S-22
<PAGE>
Class  B  CitiCertificates-- 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  "Unoffered Class B Stated  Amount" as of any  Distribution Date will be
the  lesser  of  (a)  the  Initial  Stated  Amount  of  the  Unoffered  Class  B
CitiCertificates  less (i) all amounts previously  distributed to holders of the
Unoffered Class B CitiCertificates in reduction of the Stated Amount thereof and
(ii) 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 of
Class B  CitiCertificates--Allocation  of  Losses" and  (b)  the  Pool  Adjusted
Balance  minus the  sum of  the Class A  Stated Amount  and the  Offered Class B
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 "Class  B  Stated  Amount"  as  of any
Distribution Date will  be the  Pool Adjusted Balance  less 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), 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 aggregate Servicing  Fees relating to  Mortgagor payments distributed on
the related Distribution Date. The aggregate Prepayment Interest Shortfalls with
respect to a  Distribution Date  will be allocated  proportionately between  the
CitiCertificates  and the  Residual Certificates  based on  (in the  case of the
CitiCertificates) interest  accrued thereon  or  (in the  case of  the  Residual
Certificates)  the excess of interest accrued on the Mortgage Loans over the sum
of the Servicing Fee and interest  accrued on the CitiCertificates. The  amount,
if  any, of the  Servicing Fee in  excess of the  amount of aggregate Prepayment
Interest Shortfalls  allocated  to the  CitiCertificates  will be  paid  to  the
Residual  Certificates up  to the  amount of  the Prepayment  Interest Shortfall
allocated to the Residual  Certificates. Any excess of  the amount of  aggregate
Prepayment  Interest Shortfalls  so allocated  to the  CitiCertificates over the
Servicing Fee (the "Non-Supported Interest  Shortfall") will be allocated  among
the  CitiCertificates proportionately based on  interest accrued 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 and, in
the case of the Class A-7  CitiCertificates, will reduce the amount accrued  and
added  to the Stated Amount  thereof. Any such reduction  in respect of interest
allocated to the Class A CitiCertificates  (or to the Class B  CitiCertificates)
will  be allocated among the Class A Subclasses (and, in the case of the Class B
CitiCertificates, between the Class B Subclasses) pro rata on the basis of their
respective amounts of accrued interest for such Distribution Date.

    The interest  portion of  any  Excess Special  Hazard Losses,  Excess  Fraud
Losses or Excess Bankruptcy Losses will be allocated proportionately between the
CitiCertificates  and the  Residual Certificates  based on  (in the  case of the
CitiCertificates) the interest accrued thereon and (in the case of the  Residual
Certificates)  the excess of the interest accrued on the Mortgage Loans over the
sum of  the Servicing  Fee and  the interest  accrued on  the  CitiCertificates,
between  the Class A and Class B CitiCertificates,  pro rata on the basis of the
amount of interest accrued on each such  Class and among the Class A  Subclasses
and between the Class B Subclasses, respectively, pro rata on the basis of their
respective amounts of interest accrued for such Distribution Date.

    Allocations  of the interest  portion of Realized  Losses (other than Excess
Special Hazard Losses, Excess Fraud Losses or Excess Bankruptcy Losses) first to
the  Unoffered  Class  B  CitiCertificates,  second  to  the  Offered  Class   B
CitiCertificates  and finally to  the Class A  CitiCertificates will result from
the priority  of  distributions first  to  the Class  A  CitiCertificateholders,
second  to  the  Offered  Class  B  CitiCertificateholders  and  finally  to the
Unoffered Class B CitiCertificateholders of the Pool Distribution Amount.

    On each Distribution Date  on which the Pool  Distribution Amount equals  or
exceeds  the Class  A Interest Amount,  distributions in respect  of interest to
each  Class   A  Subclass   of  Class   A  CitiCertificates   will  equal   such

                                      S-23
<PAGE>
Class  A Subclass's  Class A  Subclass Interest Amount.  Prior to  the Class A-7
Accretion Termination Date,  an amount equal  to the Class  A Subclass  Interest
Amount for the Class A-7 CitiCertificates will not be distributed as interest to
holders of the Class A-7 CitiCertificates but instead will be added to the Class
A  Subclass Stated Amount  of the Class A-7  CitiCertificates and distributed in
reduction of  the Class  A Subclass  Stated Amounts  of the  Accretion  Directed
CitiCertificates.

    In  the unlikely event that, on any Distribution Date, the Pool Distribution
Amount is  less  than  the Class  A  Interest  Amount, the  amount  of  interest
currently  distributed  on  the Class  A  CitiCertificates will  equal  the Pool
Distribution Amount and will be allocated among the Class A Subclasses pro  rata
in  accordance with the Class A Subclass  Interest Amounts. Any Class A Subclass
Interest Shortfall Amount will be added to  the amount to be distributed to  the
related Class A Subclass on subsequent Distribution Dates to the extent that the
Pool Distribution Amount is sufficient therefor and the related Class A Subclass
is  then outstanding.  No interest  will accrue on  the unpaid  Class A Subclass
Interest Shortfall Amounts.

    On each Distribution Date on which the Pool Distribution Amount exceeds  the
Class  A  Interest  Amount, any  excess  will  then be  allocated  first  to pay
previously unpaid Class  A Subclass  Interest Shortfall  Amounts of  outstanding
Class  A Subclasses. Such  amounts will be allocated  among the then outstanding
Class A Subclasses  pro rata in  accordance with the  respective unpaid Class  A
Subclass Interest Shortfall Amounts immediately prior to such Distribution Date.
Prior  to the Class A-7 Accretion Termination Date, any amounts allocated to the
Class A-7 CitiCertificates will not be  distributed to holders of the Class  A-7
CitiCertificates but will instead be added to the Class A Subclass Stated Amount
of  the Class A-7 CitiCertificates  and distributed in reduction  of the Class A
Subclass Stated Amounts of the Accretion Directed CitiCertificates.

    On each Distribution Date  on which the Pool  Distribution Amount equals  or
exceeds  the sum of (i) the Offered Class B Interest Amount and (ii) all amounts
distributable on  the  Class A  CitiCertificates,  distributions in  respect  of
interest  to the Offered Class B CitiCertificates will equal the Offered Class B
Interest Amount.

    If, on any Distribution Date, the Pool Distribution Amount is less than  the
sum   of  (i)  the  Offered  Class  B  Interest  Amount  and  (ii)  all  amounts
distributable on  the Class  A  CitiCertificates, then  the amount  of  interest
currently  distributed on  the Offered Class  B 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  Offered  Class B  Unpaid  Interest
Shortfall  will be added to the amount to  be distributed to the Offered Class B
CitiCertificates on subsequent Distribution  Dates to the  extent that the  Pool
Distribution   Amount   is  sufficient   therefor  and   the  Offered   Class  B
CitiCertificates are then outstanding.  No interest will  accrue on any  Offered
Class B Unpaid Interest Shortfall.

    If,  on any Distribution Date, the Pool Distribution Amount is less than the
sum of all amounts distributable on the Class A CitiCertificates, then the Class
B CitiCertificates will  not be entitled  to receive any  amounts in respect  of
interest or principal.

DISTRIBUTIONS IN REDUCTION OF STATED AMOUNT

    Distributions  in reduction of Stated Amount of the Class A 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
Accretion Distribution Amount, if  any, with respect  to such Distribution  Date
and  (ii) the Class A  Principal Amount 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  Class A-7  Accretion Termination  Date, the  portion of  any
payment  with respect to the Class A  Unpaid Interest Shortfall allocated to the
Class A-7 CitiCertificates  on such  Distribution Date. The  "Class A  Principal
Amount" with respect to any Distribution Date is the amount distributed pursuant
to  clause (3) 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. Amounts  distributed in  reduction of Stated
Amount  of  any   Class  A  Subclass   will  be  allocated   pro  rata  to   all
CitiCertificates of such Class A Subclass.

    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 Class A Interest Amount, any unreimbursed

                                      S-24
<PAGE>
Class  A Unpaid Interest Shortfall and the  Class A Optimal Principal Amount 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 Offered Class B CitiCertificates will be entitled to receive,
on each  Distribution  Date,  an  amount  up to  the  Offered  Class  B  Optimal
Distribution  Amount 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 Optimal
Distribution Amount" for each Distribution Date  shall equal the sum of (i)  the
Offered  Class  B Interest  Amount,  (ii) the  Offered  Class B  Unpaid Interest
Shortfall and (iii) the Offered Class B Optimal Principal Amount.

    The "Class A  Optimal Principal  Amount" with respect  to each  Distribution
Date will be an amount equal to the sum of (i) the Class A 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  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  Class  A  Prepayment 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  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 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  all partial  principal  prepayments received  by  the
Servicer  in  the month  preceding  the month  in  which such  Distribution Date
occurs.

    The "Offered  Class  B  Optimal  Principal  Amount"  with  respect  to  each
Distribution  Date will be an amount equal to the sum of (i) the Offered Class B
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  Prepayment
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 Prepayment 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  with respect to such Liquidated  Loans
and  the portion of the net Liquidation Proceeds allocated to interest, (iv) the
Offered Class B Prepayment 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
Prepayment  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 and up to
the amount of  any Realized Losses  allocated to the  Class A  CitiCertificates,
second  to the  Offered Class B  CitiCertificates, to  the extent and  up to the
amount of any Realized Losses Allocated to the Offered Class B CitiCertificates,
and then to the Unoffered Class B CitiCertificates.

    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.

                                      S-25
<PAGE>
    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
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 of the Subordinated
CitiCertificates--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 results 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  by the  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  91.75%  and 93.75%.  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 Class B CitiCertificates. The  Class
A  Percentage for each Distribution Date occurring on or after the Subordination
Depletion Date will be 100%.

    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 while,  in  the  absence of  Realized  Losses,  increasing  the
respective  interest in  the Trust  evidenced by  the Class  B CitiCertificates.
Increasing the respective interest of  the Class B CitiCertificates relative  to
that of the Class A CitiCertificates is intended to preserve the availability of
the subordination provided by the Class B CitiCertificates. See "--Subordination
of the Class B CitiCertificates" below.

    The  Class A Prepayment Percentage for any Distribution Date occurring on or
after the fifth anniversary of the  first Distribution Date will be as  follows:
for  any  Distribution  Date  subsequent  to March  1999  to  and  including the
Distribution Date in March  2000, the Class A  Percentage for such  Distribution
Date   plus  70%  of  the   Subordinated  CitiCertificate  Percentage  for  such
Distribution Date; for  any Distribution Date  subsequent to March  2000 to  and
including  the Distribution Date in March 2001,  the Class A Percentage for such
Distribution Date plus 60%  of the Class B  CitiCertificate Percentage for  such
Distribution  Date; for  any Distribution Date  subsequent to March  2001 to and
including the Distribution Date in March  2002, the Class A Percentage for  such
Distribution  Date plus 40%  of the Class B  CitiCertificate Percentage for such
Distribution Date; for  any Distribution Date  subsequent to March  2002 to  and
including    the   Distribution    Date   in    March   2003,    the   Class   A

                                      S-26
<PAGE>
Percentage for such Distribution  Date plus 20% of  the Class B  CitiCertificate
Percentage for such Distribution Date; and for any Distribution Date thereafter,
the  Class  A  Percentage for  such  Distribution  Date (unless  on  any  of the
foregoing Distribution Dates the Class A Percentage exceeds the initial Class  A
Percentage,   in  which  case  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.  Notwithstanding  the  foregoing,  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  (1)  the Adjusted  Balance  of  the  Mortgage Loans
delinquent 60 days or more averaged over the last six months, as a percentage of
the Pool Adjusted Balance averaged over the last six months, does not exceed  2%
or  (2) the percentage, averaged over any two consecutive months out of the last
three months, equal to the Adjusted Balance of all Mortgage Loans so delinquent,
divided by the Pool  Adjusted Balance, does not  exceed 2%, and (ii)  cumulative
Realized  Losses  with respect  to the  Mortgage  Loans are  less than  (a) with
respect to the  Distribution Date in  April 1999, 25%  of the aggregate  Initial
Stated  Amount of  the Class  B CitiCertificates  (the "Original  Class B Stated
Amount"), (b) with respect to  the Distribution Date in  April 2000, 30% of  the
Original  Class B Stated  Amount, (c) with  respect to the  Distribution Date in
April 2001, 35% of the Original Class  B Stated Amount, (d) with respect to  the
Distribution  Date in April 2002, 40% of the Original Class B Stated Amount, and
(e) with respect to the Distribution Date  in April 2003 and thereafter, 45%  of
the  Original Class B Stated Amount. If  on any Distribution Date the allocation
to the Class A  CitiCertificates of full and  partial principal prepayments  and
other  amounts in  the percentage  required above  would reduce  the outstanding
Class A Stated  Amount below zero,  the Class A  Prepayment Percentage for  such
Distribution  Date will  be limited  to the  percentage necessary  to reduce the
Class A Stated Amount to zero.

    The "Class B CitiCertificate Percentage"  for any Distribution Date will  be
calculated  as the difference between  100% and the Class  A Percentage for such
date. The Class B CitiCertificate Percentage on the Closing Date is expected  to
be between 6.25% and 8.25%.

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

    The  "Offered Class B Percentage" shall be  equal to (a) on any Distribution
Date on which  the Unoffered Class  B CitiCertificates are  eligible to  receive
distributions  in  reduction  of  Stated Amount,  the  percentage  calculated by
multiplying (i) the Class B CitiCertificate  Percentage by (ii) a fraction,  the
numerator  of which is the Offered Class  B Stated Amount and the denominator of
which is the sum of the Offered Class B Stated Amount and the Unoffered Class  B
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 losses on such date)  or (b) on all other Distribution Dates,
the Class B CitiCertificate Percentage for such Distribution Date.

    The "Offered Class  B Prepayment Percentage"  shall be equal  to (a) on  any
Distribution  Date on which the Unoffered  Class B CitiCertificates are eligible
to receive distributions in reduction of Stated Amount the percentage calculated
by multiplying (i)  the Class B  Prepayment Percentage by  (ii) a fraction,  the
numerator  of which is the Offered Class  B Stated Amount and the denominator of
which is the sum of the Offered Class B Stated Amount and the Unoffered Class  B
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 losses on such date)  or (b) on all other Distribution Dates,
the Class B CitiCertificate Prepayment Percentage for such Distribution Date.

    In  the  event  that  on  any   Distribution  Date,  the  Offered  Class   B
Subordination  Percentage  is  less  than  the  Offered  Class  B  Subordination
Percentage on the Closing Date, then the Unoffered 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 Offered Class B CitiCertificates.

    The "Offered Class B Subordination Percentage" is the percentage obtained by
dividing the Stated Amount of the Unoffered Class B CitiCertificates by the Pool
Adjusted Balance, both 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  Offered Class  B  Subordination
Percentage on the Closing Date is expected to be between 0.55% and 0.95%.

                                      S-27
<PAGE>
    On  any  Distribution  Date on  which  the  Stated Amounts  of  the  Class B
CitiCertificates have been reduced to zero, funds available for distribution  in
reduction  of  the  Stated  Amount  of  the  Class  A  CitiCertificates  will be
distributed pro rata  to each  Class A Subclass  notwithstanding the  priorities
described in the third paragraph under "SUMMARY OF THE PROSPECTUS AND PROSPECTUS
SUPPLEMENT--Distributions   in  Reduction  of  Stated   Amount  of  the  Offered
CitiCertificates." Under  the circumstances  described  in this  paragraph,  the
amount  allocated to each  Class A Subclass  will be distributed  pro rata among
holders of CitiCertificates of such Class A Subclass.

  DISTRIBUTIONS IN REDUCTION OF STATED AMOUNT OF THE TAC CERTIFICATES

    On each Distribution Date, the Class A Principal Distribution Amount will be
allocated among the Class A Subclasses as described under "SUMMARY OF PROSPECTUS
SUPPLEMENT--Distributions  in  Reduction  of   Stated  Amount  of  the   Offered
CitiCertificates,"  in this Prospectus Supplement. To  the extent that funds are
available to  make  distributions in  reduction  of  Stated Amount  of  the  TAC
Certificates   on  each  Distribution  Date,  each   Class  A  Subclass  of  TAC
Certificates will be  entitled to receive  its TAC Balance  Amount, if any,  for
such  Distribution Date as determined by  reference to the Targeted Balances set
forth in the table below.

    The Targeted Balances for each Class A Subclass of TAC Certificates on  each
Distribution  Date were calculated assuming that: (i) the Mortgage Loans and the
CitiCertificates  have  the  characteristics  described  below  in  the   eighth
paragraph  under "--Weighted Average  Lives of the  Offered CitiCertificates" as
used for the computation of weighted average lives, (ii) the Mortgage Loans  are
prepaid  at a  constant rate equal  to 350%  of the Prepayment  Model, (iii) the
Class A-7 CitiCertificates are not Accrual CitiCertificates, and (iv) the  Class
A-6  CitiCertificates and the  Class A-7 CitiCertificates  received 75% and 25%,
respectively, of the Class A Principal Amount assuming prepayment at a  constant
rate equal to 350% 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 any  Class A Subclass of  TAC Certificates will conform on
any Distribution  Date to  the applicable  level  set forth  in such  table.  In
addition,  if  the  Class A  Principal  Distribution Amount  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  "SUMMARY OF PROSPECTUS  AND
PROSPECTUS  SUPPLEMENT--Distributions  in  Reduction  of  Stated  Amount  of the
Offered CitiCertificates". Accordingly, if principal prepayments on the Mortgage
Loans do not  occur at  a constant  350% of  the Prepayment  Model, the  amounts
available on subsequent Distribution Dates for payment of the Class A Subclasses
of  TAC Certificates may be  less than their respective  TAC Balance Amounts for
such Distribution Dates, even if on average prepayments on the Mortgage Loans do
occur at 350%  of the  Prepayment Model.  Distributions in  reduction of  Stated
Amount  of any Class A Subclass of TAC Certificates may reduce the Stated Amount
of such  CitiCertificates  to  zero  significantly earlier  or  later  than  the
Distribution  Date specified herein. See "--Weighted Average Life 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.

SUBORDINATION OF THE CLASS B CITICERTIFICATES

    The rights  of  the 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 CitiCertificates to the extent described below  and
the  rights of the holders of the  Unoffered Class B CitiCertificates to receive
distributions with respect to  the Mortgage Loans will  be subordinated to  such
rights  of holders of  Offered Class B CitiCertificates  to the extent described
below. This  subordination  is intended  to  enhance the  likelihood  of  timely
receipt  by  holders of  the  Class A  CitiCertificates  (to the  extent  of the
subordination  of  the  Class  B  CitiCertificates)  and  the  Offered  Class  B
CitiCertificates  (to the extent  of the subordination of  the Unoffered Class B
CitiCertificates) of  the full  amount of  their scheduled  monthly payments  of
interest and principal and to afford holders of the Class A CitiCertificates (to
the extent of the subordination of the Class B CitiCertificates) and the Offered
Class  B CitiCertificates (to  the extent of the  Subordination of the Unoffered
Class B  CitiCertificates) protection  against Realized  Losses, as  more  fully
described  below. If Realized Losses exceed  the credit support provided through
subordination  to  the  Class  A   CitiCertificates  or  the  Offered  Class   B
CitiCertificates, 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 the  Class  A CitiCertificates  and/or  the Offered  Class  B
CitiCertificates.

    The  protection afforded to holders of the Class A 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  B CitiCertificates, the  amounts in reduction  of
Stated  Amount and  of interest due  the Class A  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
B CitiCertificates.

    The protection afforded to holders  of the Offered Class B  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 Unoffered  Class B  CitiCertificates, the
amounts in reduction of Stated  Amount and of interest  due the Offered Class  B
CitiCertificateholders  on each Distribution  Date out of  the Pool Distribution
Amount with  respect  to such  date  (after all  required  payments to  Class  A
CitiCertificates 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 Unoffered Class B CitiCertificates.

    The  Unoffered  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  Class  A  Interest  Amount,  any
unreimbursed  Class A Unpaid  Interest Shortfall, the  Class A Optimal Principal
Amount, the Offered Class  B Interest Amount, any  unreimbursed Offered Class  B
Unpaid  Interest Shortfall and the Offered  Class B Optimal Principal Amount for
such date. Amounts  so distributed to  Unoffered Class B  CitiCertificateholders
will  not be available to  cover delinquencies or Realized  Losses in respect of
subsequent Distribution Dates.

  ALLOCATION OF LOSSES

    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  until the  date  on  which the  amount  of  principal
payments  on the Mortgage Loans to which holders of the Class B CitiCertificates
are entitled has been reduced to zero (the "Subordination Depletion Date") as  a
result   of  the   allocation  of  losses   first  to  the   Unoffered  Class  B
CitiCertificates and second to the Offered Class B CitiCertificates.

    The subordination of the Unoffered Class B CitiCertificates in favor of  the
Class  A CitiCertificates and the Offered  Class B CitiCertificates, and that of
the Offered Class B CitiCertificates in  favor of the Class A  CitiCertificates,
is  effected by the allocation of Realized Losses first to the Unoffered Class B
CitiCertificates

                                      S-31
<PAGE>
and then  to the  Offered Class  B CitiCertificates,  until, in  each case,  the
respective Unoffered Class B Stated Amount and Offered Class B Stated Amount has
been  reduced to zero. Realized Losses will  be allocated to the Offered Class B
CitiCertificates  only  after  the  Stated  Amount  of  the  Unoffered  Class  B
CitiCertificates  has been  reduced to  zero. The  effect of  such allocation of
Realized Losses (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  CitiCertificates   and  the   Offered  Class   B
CitiCertificates.

    The  allocation of the  principal portion of  a Realized Loss  (other than a
Debt Service Reduction, Excess Special Hazard Loss, Excess Fraud Loss or  Excess
Bankruptcy  Loss) will be effected, as a result of the priority of distributions
described above, by the adjustment of the Stated Amount of the more  subordinate
Class  B Subclass then outstanding (that is,  first the Unoffered Class B Stated
Amount and then  the Offered Class  B Stated  Amount will be  adjusted) in  such
amounts  as are  necessary to cause  the sum of  the Class A  Stated Amount, the
Offered Class B Stated Amount and the  Unoffered Class B Stated Amount to  equal
the Pool Adjusted Balance.

    The  principal  portion  of any  Realized  Loss  occurring on  or  after the
Subordination Depletion Date  will be  allocated among the  outstanding Class  A
Subclasses  pro rata in accordance with  their then outstanding Class A Subclass
Stated Amounts or, in  the case of the  Class A-7 CitiCertificates, the  Initial
Stated Amount, if lower, and the interest portion of any Realized Loss occurring
on  or  after  the Subordination  Depletion  Date  will be  allocated  among the
outstanding Class  A  Subclasses pro  rata  in  accordance with  their  Class  A
Subclass  Interest  Amounts.  Any  such  losses  will  be  allocated  among  the
outstanding Class A CitiCertificates  within each Class A  Subclass pro rata  in
accordance with their respective Stated Amounts.

    Allocations  of (i) the  principal portion of  Debt Service Reductions, (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 CitiCertificates,  second,  to the
Offered  Class  B  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 on a pro rata basis between
the Class A CitiCertificates and Class B CitiCertificates based on the aggregate
Stated Amount of each such Class and the interest portion of such losses will be
allocated  proportionately  between  the   CitiCertificates  and  the   Residual
Certificates  based on  (in the case  of the  CitiCertificates) accrued interest
thereon and (in the  case of the Residual  Certificates) the excess of  interest
accrued  on the Mortgage  Loans over the  sum of the  Servicing Fee and interest
accrued on  the  CitiCertificates.  Any  interest losses  so  allocated  to  the
CitiCertificates  will be allocated on a pro  rata basis between the Class A and
Class B CitiCertificates based on accrued interest on such Class. Any losses  so
allocated   to  the  Class  A  CitiCertificates  will  be  allocated  among  the
outstanding  Class  A  Subclasses  pro  rata  in  accordance  with  their   then
outstanding  Class A Subclass  Stated Amounts or,  in the case  of the Class A-7
CitiCertificates, the  Initial Stated  Amount,  if lower,  with respect  to  the
principal  portion of  such losses  and their  amounts of  interest accrued with
respect to  the interest  portion  of such  losses,  and among  the  outstanding
CitiCertificates  within each Class A Subclass pro rata in accordance with their
respective  Stated   Amounts.  Any   losses  so   allocated  to   the  Class   B
CitiCertificates  will be allocated  between the outstanding  Class B Subclasses
pro rata in accordance with their then outstanding Offered Class B Stated Amount
and Unoffered Class B  Stated Amount, as  the case may be,  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 and
Class B CitiCertificates.

    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  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, the

                                      S-32
<PAGE>
percentage  of principal payments on the Mortgage  Loans to which holders of the
Class A 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  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 Unoffered  Class B
CitiCertificates and  then to  the Offered  Class B  CitiCertificates, but  only
prior  to the Special  Hazard Termination Date.  The "Special Hazard Termination
Date" will be the date on which 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 1.00% 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  allocated solely to  the
Class  B CitiCertificates 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   Unoffered  Class   B
CitiCertificates  and then  to the  Offered Class  B CitiCertificates,  but only
prior to the Fraud  Coverage Termination Date.  The "Fraud Coverage  Termination
Date"  will be the date on which 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 2.00% of the
Initial Mortgage Loan Balance. On  each Distribution Date thereafter, the  Fraud
Loss Amount will equal (X) prior to the first anniversary of the Cut-Off Date an
amount  equal to  the initial  Fraud Loss Amount  minus the  aggregate amount of
Fraud Losses allocated solely to the Class B CitiCertificates up to the  related
Determination  Date, and  (Y) from  the first  through 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)  1.00% of the Pool
Adjusted Balance as of the most recent anniversary of the Cut-Off Date minus (2)
the aggregate  amounts allocated  solely to  the Class  B CitiCertificates  with
respect to Fraud Losses since the most recent anniversary of the Cut-Off Date up
to  the related Determination  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 between the Class A and Class B CitiCertificates based on  their
respective  aggregate Stated Amounts.  Fraud Losses in excess  of the Fraud Loss
Amount are "Excess Fraud Losses."

    Bankruptcy  Losses  will  be  allocated  first  to  the  Unoffered  Class  B
CitiCertificates  and then  to the  Offered Class  B CitiCertificates,  but only
prior to  the Bankruptcy  Coverage Termination  Date. The  "Bankruptcy  Coverage
Termination  Date"  will  be the  date  on  which 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  0.04% 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  allocated  solely  to  the  Class  B
CitiCertificates 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)  an amount  calculated pursuant  to the  terms of the
Pooling Agreement, which amount  as calculated will provide  for a reduction  in
the  Bankruptcy Loss Amount, over (2)  the aggregate amount of Bankruptcy Losses
allocated solely to  the Class  B CitiCertificates since  such anniversary.  The
Bankruptcy  Loss Amount and  the related coverage levels  described above may be
reduced or modified  upon written confirmation  from Moody's and  S&P that  such
reduction  or modification  will not  adversely affect  the then-current ratings
assigned to  the  CitiCertificates by  Moody's  and  S&P. 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 and then
to  the   Offered   Class   B   CitiCertificates  (but   in   each   case   only

                                      S-33
<PAGE>
prior  to the related  termination date) will  be those amounts  required by the
rating agency  (or rating  agencies) rating  the Offered  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.

    The  risk of Special Hazard Losses,  Fraud Losses and Bankruptcy Losses will
be separately borne by  the 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  Initial Stated Amount.  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  and  delinquencies  resulting  from such  extraordinary  events  will be
allocated between the  Class A and  Class B CitiCertificates  pro rata based  on
their respective aggregate Stated Amounts, and, among the Class A Subclasses and
Class  B Subclasses, based on the respective then current Stated Amounts of such
Class A  Subclasses or,  in the  case  of the  Class A-7  CitiCertificates,  the
Initial Stated Amount, if lower, and Class B Subclasses.

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. The  weighted average lives of
the Offered CitiCertificates will be influenced  by the rate at which  principal
on  the Mortgage Loans is  paid. 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 of 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; "150%  of the Prepayment Model" assumes  such
Mortgage  Loans will  prepay at  rates equal to  150% 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

                                      S-34
<PAGE>
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 and  the Offered Class  B CitiCertificates 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  and the  Offered  Class B
CitiCertificates is  reduced  to  zero  is likely  to  occur  earlier  than  its
respective Last Scheduled Distribution Date.

    THE  WEIGHTED AVERAGE LIFE OF THE CLASS  A-7 CITICERTIFICATES AS WELL AS THE
YIELD TO MATURITY  OF THE CLASS  A-7 CITICERTIFICATES, TO  THE EXTENT THAT  SUCH
CITICERTIFICATES  ARE PURCHASED AT  A DISCOUNT OR  PREMIUM, WILL BE PARTICULARLY
SENSITIVE TO  THE RATE  OF  PRINCIPAL PAYMENTS  (INCLUDING PREPAYMENTS)  ON  THE
MORTGAGE  LOANS. On each Distribution  Date, the excess, if  any, of the Class A
Principal Distribution Amount over the sum  of the TAC Balance Amounts for  such
Distribution  Date will  be allocated  to the  Class A-7  CitiCertificates. As a
result, the weighted  average life  of the  Class A-7  CitiCertificates will  be
relatively  more  sensitive to  faster prepayment  rates than  those of  the TAC
Certificates, and may be significantly more sensitive than would be the case  if
the  Class  A  CitiCertificates  did  not  include  Class  A  Subclasses  of TAC
Certificates. Conversely, under  certain relatively  slow prepayment  scenarios,
the  TAC Balance Amounts for the Class  A Subclasses of TAC Certificates may not
be paid  in full  on  a given  Distribution  Date. In  such  case, the  Class  A
Principal  Distribution  Amount for  each subsequent  Distribution Date  will be
applied first to the  Class A Subclasses of  TAC Certificates until the  current
Stated  Amount  of each  such  Class A  Subclass  equals its  scheduled Targeted
Balance  and,  as  a  result,  the  weighted  average  life  of  the  Class  A-7
CitiCertificates may be extended accordingly.

    The  weighted average  lives of the  Class A Subclasses  of TAC Certificates
will depend  upon  the  particular  prepayment  scenario.  To  the  extent  that
principal  prepayments are made at rates  that are continuously slower than 350%
of the  Prepayment Model,  the weighted  average  life of  any subclass  of  TAC
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  350% of  the Prepayment Model,  the weighted  average life of  any Class A
Subclass of TAC Certificates may be reduced (and may be reduced significantly).

    The sensitivity  of the  TAC Certificates  to principal  prepayments on  the
Mortgage  Loans will  depend in part  upon the  period of time  during which the
Companion Class remains  outstanding. Under certain  relatively fast  prepayment
scenarios, one or more Class A Subclasses of TAC Certificates may continue to be
outstanding  when  the  Companion Class  is  no longer  outstanding.  Under such
circumstances, the entire Class A Principal Distribution Amount will be  applied
to  the TAC Certificates as described herein,  without regard to the TAC Balance
Amounts for such Class  A Subclasses of TAC  Certificates. Thus when the  Stated
Amount  of the Companion Class is reduced  to zero, the rate of distributions in
reduction  of  Stated  Amount  of  any  outstanding  Class  A  Subclass  of  TAC
Certificates  will become  more sensitive  to prepayment  rates on  the Mortgage
Loans. Conversely, under certain relatively slow prepayment scenarios, the Class
A Principal Distribution  Amount may not  be sufficient to  pay the TAC  Balance
Amounts  for all Class A Subclasses of  TAC Certificates on a given Distribution
Date. In such  cases, the Class  A Principal Distribution  Amount for each  such
subsequent  Distribution Date will be  applied to the Class  A Subclasses of TAC
Certificates in  accordance  with  the priorities  described  herein  until  the
outstanding  Stated Amount  of each such  Class A Subclass  equals its scheduled
Targeted Balance, and the weighted average life  of any Class A Subclass of  TAC
Certificates  that did not receive its TAC 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  will be entitled to receive the  Class A Percentage of all the
Scheduled Principal, and the Class A  Prepayment Percentage of the net  Adjusted
Balance  or  net  proceeds  (as  applicable)  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 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

                                      S-35
<PAGE>
the  indicated percentages of the Prepayment Model  set forth in the table; (ii)
each Mortgage Loan will have an original term to maturity of 360 months and each
Mortgage Loan will have a  remaining term to stated  maturity of 343 months  and
will bear interest at the rate of 7.375% per annum; (iii) CMSI does not exercise
its  right of  optional termination; (iv)  the Initial Mortgage  Loan Balance is
approximately $258,891,390, the Initial Stated  Amount of the Unoffered Class  B
CitiCertificates is $1,941,686 and the Initial Stated Amount and the Stated Rate
of  each  Subclass of  the  Class A  CitiCertificates  and the  Offered  Class B
CitiCertificates are as set forth on the cover page hereof; (v) the Closing Date
is March 29,  1994; and (vi)  distributions to holders  of the  CitiCertificates
will  be made on the 25th day of each month commencing April 1994 (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  outstanding (and the weighted average
lives) of the Class  A Subclasses and the  Offered Class B CitiCertificates  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 of each Class A Subclass and the Offered Class B
CitiCertificates 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 Mortgage Loans will have mortgage interest rates of 7.375% per annum.
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 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 is 343 months.

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

(1)   The  weighted  average  life of  each  Class  A Subclass  of  the  Class A
      CitiCertificates and the Offered Class B CitiCertificates is determined by
      (i) multiplying the  amount of  each distribution in  reduction of  Stated
      Amount  by the number  of years from the  date of issuance  of the Class A
      CitiCertificates and the Offered Class  B CitiCertificates to the  related
      Distribution  Date, (ii) adding the results  and (iii) dividing the sum by
      the Initial  Stated  Amount  of  the  Class A  Subclass  of  the  Class  A
      CitiCertificates  (or with respect to  the Class A-7 CitiCertificates, the
      highest Stated Amount thereof) or the Offered Class B CitiCertificates, as
      the case may be.

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 and  the Offered  Class B  CitiCertificates and  the timing  and
extent  of losses,  if any,  allocable to the  Class A  and the  Offered 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 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  prior
to  the Class  A 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  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  CitiCertificates  prior   to  the  Class  A
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
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.

YIELD CONSIDERATIONS WITH RESPECT TO THE OFFERED CLASS B CITICERTIFICATES

    The  following   yield  table   with  respect   to  the   Offered  Class   B
CitiCertificates  has 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 that
liquidations occur monthly at  the rates equal to  the following percentages  of
the  Initial Mortgage Loan Balance for the  number of months indicated (and none
thereafter):

               2.00%                                    60
</TABLE>

    For example,  if 0.50%  of  the Mortgage  Loans liquidate,  one-sixtieth  of
$1,294,457  (which is the product of  $258,891,390 and 0.50%) would liquidate in
each month over a 60-month period, commencing in month 25.

    In addition, it was assumed that (ii) realized losses on liquidations of 20%
of the  outstanding principal  balance  of such  liquidated Mortgage  Loans,  as
indicated    in    the   table    (referred   to    as   the    "Loss   Severity

                                      S-40
<PAGE>
Percentage"), will occur at the time of liquidation. Thus, in the above example,
assuming that 0.50%  of the aggregate  principal balance of  the Mortgage  Loans
were  liquidated, an  assumed Loss  Severity Percentage  of 20%  would result in
realized losses of  $258,891, or  $4,315 per month;  (iii) there  are no  Excess
Special  Hazard Losses,  Excess Fraud Losses  or Excess  Bankruptcy Losses; (iv)
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 (v) there are no Non-Supported
Interest Shortfalls.

    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  table were  calculated by
determining the monthly  discount rates  which, when applied  to the  respective
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 March  29, 1994  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) March  29, 1994, 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 Stated
Amount on the Offered Class B CitiCertificates and consequently does not purport
to  reflect the return on any investment in the Offered Class B CitiCertificates
when such reinvestment rates are considered. The assumed purchase price is equal
to the percentage stated in the 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.   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  in  an  amount  equal  to the
outstanding Stated Amount of each  Class thereof together with accrued  interest
thereon.

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.

                                      S-41
<PAGE>
SERVICING COMPENSATION

    CMSI  will act as servicer  of the Mortgage Loans  as well as REMIC servicer
for the  Pool  (together,  the "Servicer")  and  as  such will  be  entitled  to
Servicing Compensation equal to a monthly fee of .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
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

    The Class A CitiCertificates initially will be issued in book-entry form and
will each 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
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-

                                      S-42
<PAGE>
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  Offered Class  B CitiCertificates 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  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  certificates  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 Offered  Class  B
CitiCertificates.  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) 230-2861.

                              ERISA CONSIDERATIONS

    The  Department of  Labor has granted  to the  Underwriter an administrative
exemption (the "Exemption") from certain of the prohibited transaction rules  of
ERISA  and certain of the  excise taxes imposed by 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 Class A 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  Class A  CitiCertificates  are the
following: (1) the acquisition of the Class A 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  Class A
CitiCertificates acquired by the ERISA Plan  are not subordinated to the  rights
and

                                      S-43
<PAGE>
interests  evidenced  by  other  certificates  of the  Trust;  (3)  the  Class A
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,  Moody's, Duff & Phelps  Credit Rating Co. or  Fitch
Investors  Service, Inc.; (4) the sum of all payments made to the Underwriter in
connection with the distribution of the Class A 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 Class A
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  Class A
CitiCertificates by ERISA Plans  sponsored by the  Issuer, the 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 does not exceed  25% of all 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.

    Neither the Exemption nor PTE  83-1 (discussed under "ERISA  CONSIDERATIONS"
in  the Prospectus) applies to the acquisition or holding of the Offered Class B
CitiCertificates because such CitiCertificates are  subordinated to the Class  A
CitiCertificates. Accordingly, no transfer of an Offered Class B 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 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 (ii) upon the delivery of an opinion of  counsel
in  form and substance satisfactory to the  Trustee that the purchase or holding
of 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.

    Fiduciaries of Plans should consult their  legal advisors, and refer to  the
discussion under "ERISA CONSIDERATIONS" in the Prospectus.

                                LEGAL INVESTMENT

    The  Class A 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  Underwriter (the  "Underwriting Agreement"), the
Offered CitiCertificates are being purchased from the Issuer by the  Underwriter
upon  issuance.  The Underwriter  is committed  to purchase  all of  the Offered
CitiCertificates  offered  hereby   if  any   CitiCertificates  are   purchased.
Distribution    of    such    CitiCertificates   is    being    made    by   the

                                      S-44
<PAGE>
Underwriter 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
97.531101%   of   the  aggregate   Initial  Stated   Amount   of  the   Class  A
CitiCertificates and 90.166666667% of the aggregate Initial Stated Amount of the
Offered Class B CitiCertificates, plus accrued interest in each case at the rate
of 6.25% per annum from the  Cut-Off Date but before deducting expenses  payable
by the Issuer, provided that if the aggregate Initial Stated Amount of the Class
A  CitiCertificates is  less than  $241,150,000, 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 .003%, and
if the  aggregate Initial  Stated  Amount of  the  Class A  CitiCertificates  is
greater  than $241,150,000,  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  .003%. In
connection with  the purchase  and  sale of  the Offered  CitiCertificates,  the
Underwriter  may be deemed to have received  compensation from the Issuer in the
form of underwriting discounts.

    Subject to  the  terms  and  conditions  of  the  purchase  agreement  among
Citicorp,  the  Issuer  and Prudential  Securities  Incorporated  (the "Purchase
Agreement"), the Unoffered  Class B  CitiCertificates (not  offered hereby)  are
being  purchased by Prudential Securities Incorporated upon issuance. Prudential
Securities Incorporated is committed  to purchase all of  the Unoffered Class  B
CitiCertificates  if any Unoffered  Class B CitiCertificates  are purchased. The
Unoffered Class B CitiCertificates will be offered through Prudential Securities
Incorporated 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  Agreement  provides  that the  Issuer  and  Citicorp  will
indemnify the Underwriter against certain civil liabilities under the Securities
Act or contribute to payments the Underwriter may be required to make in respect
thereof.

                                 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
Underwriter 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.

                       CITICORP MORTGAGE SECURITIES, INC.
                        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") 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  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 other  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  terms  of   any  distributions  on  Residual
Certificates; and any other terms of a Class or Subclass.

    Each Pool will consist of fixed  or adjustable interest rate mortgage  loans
("Mortgage  Loans") acquired by the Issuer from Citicorp Mortgage, Inc. ("CMI"),
Citibank, N.A. ("Citibank")  or another affiliate  of the Issuer  (collectively,
the   "Originators")   and/or   of  certificates   backed   by   Mortgage  Loans
("CitiMortgageCertificates"), 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, or a Reserve Fund as described herein and  in
the  related  Prospectus Supplement,  or  by the  subordination  of one  or more
Classes

                                       3
<PAGE>
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 such Prospectus
Supplement if,  at  the  time  of  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.

    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 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.

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 by or on behalf of the Issuer 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 (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.

                                       4
<PAGE>
    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);

        (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    under    "THE    MORTGAGE    LOANS   AND
     CITIMORTGAGECERTIFICATES--Realization Upon Defaulted Mortgage Loans" below;
     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 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

                                       5
<PAGE>
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  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 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

                                       6
<PAGE>
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,  or, 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 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 the  Class
of  CitiCertificates  then entitled  to  receive distributions  in  reduction of
Stated Amount  (a  "Loss  Allocation  Event"), the  amount  then  available  for
distribution  will be distributed 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.
Thereafter   funds  on  deposit   in  the  Certificate   Account  available  for
distributions in  reduction of  Stated Amount  on a  Distribution Date  will  be
distributed  on such Distribution Date pro  rata based on the outstanding Stated
Amount to all Classes  of CitiCertificates then  outstanding. 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  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.

                                       7
<PAGE>
    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  initial deposit into  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
Special  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  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, 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 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.

                                       8
<PAGE>
    SUBORDINATION

    If so specified in the 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  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.

    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 will be set forth
in the Prospectus Supplement relating to such Series.

                                       9
<PAGE>
    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,  which  amount will  be  set  forth in  the  related  Prospectus
Supplement.  The amount  and principal  terms of any  such coverage  will be set
forth in the 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 (as defined in  APPENDIX
A)  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 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

                                       10
<PAGE>
consolidated or by 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 as compensation for issuance of the 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.

    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)  and (b) are 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."

                                       11
<PAGE>
    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 intend 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
"Prepayment Considerations and Weighted Average Life."

PREPAYMENT CONSIDERATIONS AND WEIGHTED AVERAGE LIFE

    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 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

                                       12
<PAGE>
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  Certificates  of  a  Series.  Such  Residual
Certificates may be sold together with  or separately from such Certificates  or
may  be retained by the Issuer or  the related Originator 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
Certificates 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"), 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 to CMI (or its designated subservicer). 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 66 2/3% 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")  and (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  ("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."  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  cash, if any, initially deposited  in
the  Certificate Account, (iii) amounts deposited  in any Reserve Fund described
in the

                                       13
<PAGE>
Prospectus Supplement, (iv) distributions  on such Mortgage Certificates  and/or
Mortgage  Loans  (net  of  any  servicing  compensation)  and  (v)  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 CITI-
MORTGAGECERTIFICATES."

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  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. 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. Mortgage Loans in  a Pool will  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  from
$10,000  to  $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 any of the following types:

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

        (ii)  growing  equity  Mortgage  Loans  providing  for  scheduled annual
    payment increases at rates  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  amortized over a  fixed number of  years but which
    have shorter terms to maturity that causes the outstanding principal balance
    of the related Mortgage Loan to be due  and payable at the end of a  certain
    specified period; or

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

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 will be subject to
limits on the magnitude

                                       14
<PAGE>
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 impact of any
such negative  amortization  on Certificateholders  will  be set  forth  in  the
Prospectus Supplement.

    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,  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 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.

    The  properties  securing Mortgage  Loans  may consist  of  detached houses,
attached houses, condominiums  or planned  unit developments 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 will be located in one of the
fifty United States or the District of Columbia.

    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 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." 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, and assignments of the  Mortgage by the Originator to the
Trustee. Such assignments  will generally  be recorded.  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
Originators.  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 (in such
capacity, the  "Servicer"  or  "servicer")  of  such  Mortgage  Loans  (or  will
subcontract with an affiliate to act as subservicer). The Mortgage Loans will 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  the related 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 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  defined  as  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 entity,  including  an
entity  more than 50% of the stock of which is owned, directly or indirectly, by
Citicorp. Each  of  Citibank and  CFSB  intends  to subcontract  its  duties  as
servicer  under each Pooling Agreement  under which it acts  as servicer to CMI.
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

                                       16
<PAGE>
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.

    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 the Federal  National Mortgage Association
("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 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 will not  bear interest, except  to
the  extent represented by returns on Eligible Investments. 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.  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

                                       17
<PAGE>
States  or of  any agency  thereof backed by  the full  faith and  credit of the
United States, certificates of deposit,  time deposits and bankers'  acceptances
sold  by eligible commercial  banks (including affiliates of  the Issuer such as
Citibank, N.A.), 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"),  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.

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.  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. See  "Substitution of  Mortgage
Loans."

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.

                           LOAN UNDERWRITING POLICIES
                    AND LOSS AND DELINQUENCY CONSIDERATIONS

LOAN UNDERWRITING POLICIES OF THE 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
Originators  are  subject  to  the   same  underwriting  process.  For   certain
residential  mortgage loans  the Originators  have contracted  with unaffiliated
third parties to  perform the  underwriting process.  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  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 adverse shifts in  real
estate  values. In  general, it  is the  policy of  each Originator  not to make
conventional  one-to  four-family   real  estate  loans   with  more  than   90%
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  90%
loan-to-value  ratio.  Since  February 1993,  it  has  been the  policy  of each
Originator not to make one-to  four-family real estate loans with  loan-to-value
ratios above 80% without obtaining primary mortgage insurance.

    Each  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 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), and a credit
report which summarizes  the prospective  borrower's credit  history with  local
merchants  and lenders and any record of bankruptcy. Since February 1991, it has
been the policy of each Originator to obtain at least two credit reports  (which
may  be in  the form  of an  expanded credit  bureau report)  with respect  to a
prospective borrower. Self-employed prospective borrowers are required to submit
their federal income tax returns  for the most recent  two years and a  separate
statement  of income and expenses.  In the case of  mortgage loans originated or
acquired after July  1993 by  the Originators (other  than Citibank),  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 Originator at the origination of such mortgage loan or the sale price for
such  property (the "Original Value"), 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 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  living expenses.  Each 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. Where there are two individuals co-signing the mortgage note or
documents,  the income and debt of both  are included in the computation. In the
case

                                       21
<PAGE>
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
assure satisfaction of the Originator's lending guidelines.

    Since  April 1991, each 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.

    Each 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 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. Neither the independent  appraisers
nor  employees receive any compensation dependent  upon either the amount of the
loan or its consummation. In normal  practice, the 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 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.  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  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,  the
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.

    An  Originator  may  originate  loans  on  residential  leasehold properties
("Leasehold Loans").  Leasehold  Loans  are approved  in  accordance  with  such
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 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 Originator requires that the leasehold
estate be assignable or  transferable if it is  subjected to the mortgage  lien.
The land lease should guarantee such 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
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 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 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 Originator not  to make one-to
four-family real  estate  loans  with loan-to-value  ratios  above  80%  without
obtaining primary mortgage insurance.

    Each   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
(as defined in  APPENDIX A),  the borrower's  repayment ability  will have  been

                                       22
<PAGE>
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
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 Originator  originates  Buydown  Mortgage  Loans  as  defined  in  "THE
POOLS--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 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 Originators (other than Citibank) purchase  mortgage
loans  originated by other  parties. Mortgage loans  acquired from other parties
are reviewed  by  such  Originators  or  by  unaffiliated  third  parties  under
contracts  with  such  Originators  for  compliance  with  the  above  described
underwriting criteria, and such Originators have the right to reject loans which
fail to conform to such criteria.

    The Mortgaged Properties (as defined in APPENDIX A) may be located in 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
Originator's    underwriting   standards   in   all   states   (including   such
anti-deficiency states) require loan underwriters to be satisfied that the value
of the  property  being  financed,  as indicated  by  the  appraisal,  currently
supports  and  is anticipated  to  support in  the  future 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."

    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  under "DELINQUENCY AND  FORECLOSURE
EXPERIENCE."  In particular, delinquencies,  defaults and foreclosures generally
occur with greater frequency in the second through fifth years of the life of  a
mortgage  loan  which  has  a 30-year  scheduled  maturity.  The  Mortgage Loans
underlying the CitiMortgageCertificates or the Certificates may have a different
range of  remaining  maturities from  those  represented by  the  tables  below.

                                       23
<PAGE>
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  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 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.

                  DELINQUENCY, FORECLOSURE AND LOSS EXPERIENCE

DELINQUENCY AND FORECLOSURE EXPERIENCE OF 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 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 decreased from  $55.9 billion on  December
31,  1991 to $39.0 billion on December  31, 1993. 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 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 Originators,  CMSI and certain other affiliates  of
CMI  pursuant to registration statements under the  1933 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  $11.8 billion on December  31, 1991 to $7.7  billion on December 31, 1993.
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,  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.

                                    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,
CBNA and Citibank, 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.

                                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

           (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

    For each Series, the Trustee will send to holders of Residual Certificates a
statement setting forth the information in paragraphs (i) through (ix).

    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 3.04)

    In  addition  to the  foregoing, the  Trustee shall  file with  the Internal
Revenue Service and applicable state and  local taxing authority 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 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 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 Mortgage Loans. (Section 3.08)

    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  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 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 12.01)

    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
CitiCertificates and of more than 66 2/3% of

                                       27
<PAGE>
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 "THE POOLING AGREEMENTS--Amendment." (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  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 the issuer of any form
of credit  support  or  to  the  Issuer  and  the  Trustee  by  the  holders  of
Certificates  evidencing ownership  interests aggregating  not less  than 25% of
each Class affected, and of the Residual

                                       28
<PAGE>
Certificates, if affected, by such failure (each such Class and (if  applicable)
the Residual Certificates, an "Affected Class"); (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 the
issuer of any form  of credit support or  to the Issuer and  the Trustee by  the
holders of Certificates evidencing ownership interests aggregating not less than
25%  of each Affected Class; 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 Certificates evidencing ownership
interests aggregating not less than 25% of any Affected Class 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 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 25% of  each Affected Class 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

                                       29
<PAGE>
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, the issuer of credit support and the Trustee with the consent of the
holders of Certificates evidencing ownership interests aggregating not less than
66  2/3% of each Affected  Class 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 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)

    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 herewith.

    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

                                       30
<PAGE>
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  (not to exceed  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  (A) constituting a
"qualified liquidation" within  the meaning of  Section Code 860F(a)(4)(A),  (B)
not  adversely affecting  the REMIC  status of each  Pool and  (C) 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). (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 and  loan
association  or  trust  company  serving  as  Trustee  may  have  normal banking
relationships with the Issuer or the Originator. 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
at  least 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)

                              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 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 (as defined in APPENDIX A).

                                       32

    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 defined in  APPENDIX A) 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

                                       33
<PAGE>
"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  (the "Enhancement Act"), 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," they will be legal  investments for persons, trusts,  corporations,
partnerships,  associations, business  trusts and  business entities (including,
but not limited to, state-chartered savings banks, commercial banks, savings and
loan associations  and  insurance  companies,  as well  as  trustees  and  state
government  employee retirement systems)  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  the Enhancement Act, 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  the  Enhancement   Act.
Accordingly,  the investors affected  by such legislation  will be authorized to
invest in the Senior Certificates, and if so specified in the related Prospectus
Supplement, the Subordinated Certificates and the Residual Certificates, only to
the extent provided in such legislation.

    The Enhancement Act 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
with mortgage  related securities  without limitation  as to  the percentage  of
their  assets represented thereby, federal credit  unions may invest in mortgage
related securities, and national banks may purchase mortgage related  securities
for  their own account without regard to the limitations generally applicable to
investment securities set  forth in  12 U.S.C. Section24  (Seventh), subject  in
each case to such regulations as the applicable federal regulatory authority may
prescribe.  In  this connection,  federal credit  unions should  review National
Credit Union Administration  (the "NCUA")  Letter to  Credit Unions  No. 96,  as
modified by Letter to Credit Unions No. 108, which includes guidelines to assist
federal  credit  unions  in  making investment  decisions  for  mortgage related
securities.   The   NCUA   has   adopted   rules,   codified   as   12    C.F.R.
Section703.5(f)-(k),  which  prohibit federal  credit  unions from  investing in
certain mortgage  related  securities  (including  securities  such  as  certain
Series,   Classes  or   Subclasses  of   Certificates),  except   under  limited
circumstances.

    All depository institutions  considering an investment  in the  Certificates
should   review  the   Federal  Financial   Institutions  Examination  Council's
"Supervisory Policy Statement on Securities  Activities" dated January 28,  1992
(the  "Policy Statement"). The  Policy Statement, which has  been adopted by the
Board of Governors of the Federal  Reserve System, the FDIC, the Comptroller  of
the  Currency and the  OTS, effective February  10, 1992, and  by the NCUA (with
certain  modifications),   effective  June   26,  1992,   prohibits   depository
institutions   from  investing   in  certain   "high-risk  mortgage  securities"
(including  securities  such  as  certain  Series,  Classes  or  Subclasses   of
Certificates),  except  under  limited  circumstances,  and  sets  forth certain
investment practices deemed to be unsuitable for regulated institutions.

                                       34
<PAGE>
    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 may be deemed  unsuitable
investments,  or  may otherwise  be restricted,  under  such rules,  policies or
guidelines (in certain instances irrespective of the Enhancement Act).

    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.

    INVESTORS  SHOULD  CONSULT  WITH  THEIR OWN  LEGAL  ADVISORS  IN DETERMINING
WHETHER AND TO  WHAT EXTENT  THE CERTIFICATES CONSTITUTE  LEGAL INVESTMENTS  FOR
SUCH INVESTORS.

                    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 on December  23, 1992, and generally  effective for REMICs with
Startup Days on or after November  12, 1991. 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  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 for  Asset  Securitization 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 mutual savings bank  or a domestic building and loan
association will constitute "qualifying real property loans" within the  meaning
of  Code Section 593(d)(1) in  the same proportion that  the assets of the REMIC
would be  so  treated.  Certificates  held  by  a  domestic  building  and  loan
association

                                       35
<PAGE>
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"
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)(5)(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  Sections  593(d)(1)  and
856(c)(5)(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 "qualifying real property loans" or "loans . . . secured by
an interest  in real  property"  for purposes  of  Code Sections  593(d)(1)  and
7701(a)(19)(C)(v),  respectively, 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)(4)(A)(i). Certificates held by certain  financial
institutions  will constitute "evidence  of indebtedness" within  the meaning of
Code Section 582(c)(1).

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."

    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

                                       36
<PAGE>
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 held  for not  more than  two years,  with extensions  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 a qualified
variable or inverse variable rate 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, 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  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 level 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  under Code Sections  1271 through 1273  and 1275 (the "OID
Regulations") and in part on the provisions of the 1986 Act. The OID Regulations
generally are effective for debt instruments  issued on or after April 4,  1994,
but  may  be relied  upon  as authority  with  respect to  the CitiCertificates.
Alternatively, proposed Treasury  regulations issued  December 21,  1992 may  be
relied  upon for  debt instruments  issued prior  to April  4, 1994.  Holders of
CitiCertificates should be aware, however, that neither the OID Regulations  nor
the   proposed  regulations  adequately  address   certain  issues  relevant  to
prepayable securities, such as the  CitiCertificates. To the extent such  issues
are  not  addressed in  the OID  Regulations,  the Issuer  intends to  apply the
principles of such regulations and  the methodology described in the  Conference
Committee  Report  to the  1986 Act.  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  includable 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). Althought  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. Under  the OID  Regulations,  pre-issuance accrued  interest need  not  be
included  in the issue price (or the  stated redemption price at maturity) of an
obligation, such  as a  CitiCertificate, on  which interest  distributed on  the
first  Distribution  Date  exceeds  the  amount  of  such  pre-issuance  accrued
interest. In  this case,  the  pre-issuance accrued  interest  is deemed  to  be
recovered on the first Distribution Date. However, the Issuer intends to include
such  pre-issuance  accrued interest,  if  any, in  the  issue price  and stated
redemption price of a CitiCertificate.  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. No distributions  on an Accrual  CitiCertificate, or on  other
CitiCertificates  with respect to  which interest distributions  may be deferred
and added to the Stated

                                       38
<PAGE>
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.  As described
below, the Issuer  intends to use  an accrual period  for purposes of  computing
original  issue discount that  corresponds to the calendar  month, other than in
the case of a variable rate CitiCertificate on which interest accrues based on a
non-calendar month  accrual  period.  Investors should  consult  their  own  tax
advisors  to  determine  the issue  price  and  the stated  redemption  price at
maturity of a CitiCertificate.

    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
and   the  anticipated   reinvestment  rate,  if   any,  used   in  pricing  the
CitiCertificates (the "Prepayment Assumption").  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."

    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.  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 in  the calendar year corresponding to the last  day
of  the related interest  accrual period 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.

                                       39
<PAGE>
    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
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
below under the heading "Election to Treat All Interest Under the Constant Yield
Method."

    VARIABLE RATE CITICERTIFICATES

    CitiCertificates may provide for  interest based on  a variable rate.  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 of not less than zero nor more 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 includes  a
rate  determined using a single  fixed formula and that is  based on one or more
qualified floating rates or the yield or changes in the price of actively traded
personal property. 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. 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  an  interest-only   or
super-premium  floating rate, or a  fixed rate for one  year or more followed by
the inverse of an index multiplied by more than 1.35. It is possible that such a
Class may be  considered to bear  "contingent interest," within  the meaning  of

                                       40
<PAGE>
proposed   Treasury  regulations  issued  on   April  8,  1986.  These  proposed
regulations under certain circumstances could result in a deferral of the timing
of reporting  of  such interest  income  when  compared to  the  original  issue
discount  rules. However, the proposed regulations regarding contingent interest
have not  been adopted  in final  form and  may not  currently be  relied  upon.
Moreover, 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  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 interest  under this  rule as 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
non-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. 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

                                       41
<PAGE>
distributable in 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 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 the Code Section 171 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. 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. 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. To the extent the rules  of
Code  Section 166 regarding bad debts are applicable, it appears that holders of
CitiCertificates that are corporations 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 will be allowed to deduct as a short term capital loss any loss
sustained during the taxable year on

                                       42
<PAGE>
account  of a  portion of any  such CitiCertificates  becoming wholly worthless.
Although  the  matter  is  not   free  from  doubt,  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.  Losses  attributable  to   interest
previously  reported as income  should be deductible as  ordinary losses by both
corporate and non-corporate holders. 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. 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
debt instruments 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 and by any amortized
premium.

    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  or   short-term  depending   on  whether   the
CitiCertificate  has been  held for  the long-term  capital gain  holding period
(currently more than one year). 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 in effect  at the time  the 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, (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

                                       43
<PAGE>
(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
under  Code Section 1274(d) 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). Pursuant to the Revenue
Reconciliation Act of 1993, capital gains of certain non-corporate taxpayers are
subject  to a lower maximum tax rate than ordinary income of such taxpayers. 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
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)   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 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

                                       44
<PAGE>
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

                                       45
<PAGE>
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.   Generally,  the REMIC's  deductions for original
issue discount will be determined in the same manner as original issue  discount
income   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.

    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). In
respect of mortgage loans  described above which have  market discount to  which
Code  Section 1276 applies, the accrued portion of such market discount would be
recognized currently as an item of REMIC ordinary income. 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 a  level 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

    The  Code  provides that,  to  the extent  provided  in regulations,  if the
aggregate value of the Residual Certificates relative to the aggregate value  of
the  CitiCertificates and Residual Certificates is considered to be "significant
as described below," then a  portion (but not 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. Although the Conference Committee Report to
the 1986 Act  indicates that  the value of  all Residual  Certificates would  be
considered significant in cases where such value is at least 2% of the aggregate
value  of the CitiCertificates and  Residual Certificates, the REMIC Regulations
have not adopted such a general rule. Accordingly, the

                                       46
<PAGE>
portion of the REMIC's taxable income that will be treated as excess  inclusions
will  be determined by the  preceding formula, with the  effect that such excess
inclusions will be a larger portion of such income as the relative value 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 carryforwards, on such Residual Holder's return. 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 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.

    An  exception  to  the  inability  of a  Residual  Holder  to  offset excess
inclusions with unrelated deductions  and net operating  losses applies to  Code
Section  593 institutions ("thrift institutions"). For purposes of applying this
rule, all  members of  an  affiliated group  filing  a consolidated  return  are
treated  as one taxpayer, except that  thrift institutions to which Code Section
593 applies,  together  with their  subsidiaries  formed to  issue  REMICs,  are
treated   as  separate   corporations.  Furthermore,  the   Code  provides  that
regulations may disallow the ability of  a thrift institution to use  deductions
to offset excess inclusions if necessary or appropriate to prevent the avoidance
of  tax. A thrift institution may not so offset its excess inclusions unless the
Residual Certificates  have "significant  value," which  requires that  (i)  the
Residual  Certificates have an issue  price that is at least  equal to 2% of the
aggregate of the issue prices of all Residual Certificates and  CitiCertificates
with respect to the REMIC, and (ii) the anticipated weighted average life of the
Residual  Certificates is at least 20%  of the anticipated weighted average life
of the REMIC. The anticipated weighted average life of the Residual Certificates
is  based  on  all  anticipated  distributions  thereon  using  the   Prepayment
Assumption.  The anticipated weighted average life of the REMIC is the aggregate
weighted average life of  all classes of interests  therein (computed using  all
anticipated  distributions on a regular interest  with nominal or no principal).
Finally, an ordering  rule under the  REMIC Regulations provides  that a  thrift
institution may only offset its excess inclusion income with deductions after it
has  first applied  its deductions against  income that is  not excess inclusion
income. If applicable, the Prospectus Supplement  with respect to a Series  will
set  forth whether the  Residual Certificates are  expected to have "significant
value" within the meaning of the REMIC Regulations.

    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

                                       47
<PAGE>
transfer if  the transferee  furnishes  to the  transferor an  affidavit,  under
penalties  of perjury,  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  interest  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 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
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, and (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.

    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 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"  (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

                                       48
<PAGE>
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  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, or an estate  or
trust that is subject to U.S. 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.

                                       49
<PAGE>
    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.

    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 Certificates 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 of  two years,  with
possible  extensions. 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 recognize no gain  or loss 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.  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. 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  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

                                       51
<PAGE>
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.

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
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
statement, 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 statement, or any other  required
statement,  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.

    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.

                                       52
<PAGE>
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.

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.

                                       53
<PAGE>
    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  Citicorp
will  indemnify  the  several underwriters  against  certain  civil liabilities,
including liabilities under the Securities Act of 1933.

    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  of 1933 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.

                  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
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," and  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."  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"). The information contained herein in respect of CMI Pools applies
generally to Mortgage Loans originated by other affiliates and contained in CMSI
Pools.  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"). 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 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 less than $10,000 or 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  of the  fifty states  of the  United States  or the
District of Columbia,  (iv) be  fixed rate or  adjustable rate  loans which  may
provide    for    full    amortization    of    principal,    deferral    of   a

                                      A-1
<PAGE>
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 90% 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 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  (as
defined  below) 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  Securities and  Exchange 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. 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)  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 affiliate of Citicorp. The Prospectus Supplement will not include the  amount
of  the subordinated loan in the loan-to-value calculation included therein. 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 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 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  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 Originator not to make one-to four-family real estate loans  with
loan-to-value ratios above 80% without obtaining primary mortgage insurance.

    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 (as defined herein) 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  Securities  and  Exchange
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 in a Pool pursuant to the related Pooling Agreement. The Issuer may at any
time delegate or subcontract any duties as servicer under any Pooling  Agreement
to  any  corporation, including  a corporation  more  than 50%  of the  stock of

                                      A-3
<PAGE>
which is owned, directly or  indirectly, by Citicorp. In  the event of any  such
delegation  or subcontract, the Issuer will remain responsible for the delegee's
or subcontractor's performance in accordance with the Pooling Agreement.  Unless
otherwise  specified in  the applicable  Prospectus Supplement,  the Issuer will
subcontract its duties as servicer under the related Pooling Agreement to CMI. 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. 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."

    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 AND FORECLOSURE 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 (as defined
below)  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  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
    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

                                      A-4
<PAGE>
    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  amortized over a  fixed number of  years but  which
    have  a  shorter  term to  maturity  that causes  the  outstanding principal
    balance of the related Mortgage Loan to be  due and payable at the end of  a
    certain specified period; or

        (v)  such 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 (as  defined below) 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.

    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

                                      A-5
<PAGE>
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 and will always exceed
the   interest    passed   through    to   the    holders   of    the    related
CitiMortgageCertificate  or CitiCertificate. 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."

    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. Interest
on  such a full or partial  prepayment will be paid 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)  for such  calendar month. Therefore,  to the  extent such Servicing
Compensation 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.

                                      A-6
<PAGE>
    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
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.

                      underlying ARMs.
</TABLE>

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  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."

    The  general  experience  of  the  Federal  Housing  Administration  ("FHA")
relating  to  FHA insured  fixed-rate level  payment  mortgage loans  at various
interest rates  with  original maturities  of  15  to 30  years  and  permitting
assumption  by a buyer  if a home is  sold is that a  substantial number of such
mortgage loans are prepaid, and that only a significantly smaller number of such
mortgage  loans  remain  outstanding  until  their  scheduled  maturities.  Data
relating  to such mortgage loans for the period 1970 to 1983, as compiled by the
Department of Housing  and Urban  Development ("HUD"),  indicates, for  example,
that  for a pool of such 30-year mortgage loans having mortgage rates of 12% per
annum, the aggregate  principal balance  of such mortgage  loans outstanding  12
years  after origination  is expected to  be approximately 46%  of the aggregate
original principal balance of such mortgage loans. By comparison, 90.87% of  the
aggregate  original principal  balance of  such mortgage  loans would  have been
outstanding if such mortgage loans had amortized in

                                      A-7
<PAGE>
accordance with the applicable repayment schedules, without any prepayments.  It
is  customary in the  mortgage industry in  quoting yields on  a pool of 30-year
mortgages to  compute the  yield as  if  the pool  were a  single loan  that  is
amortized according to a 30-year schedule and then is prepaid in full at the end
of the 12th year.

    The HUD data also indicates that for a pool of 15-year mortgage loans having
mortgage  rates  of  12% per  annum,  the  aggregate principal  balance  of such
mortgage  loans  outstanding  7  years  after  origination  is  expected  to  be
approximately  40% of the aggregate original  principal balance of such mortgage
loans. By comparison, 73.84% of the aggregate original principal balance of such
mortgage loans would have been outstanding if such mortgage loans had  amortized
in accordance with the applicable repayment schedules, without any prepayments.

    There  can be no assurance that the rate of prepayment of the Mortgage Loans
will conform to FHA  experience. There are  substantial differences between  the
composition  of the mortgage loan portfolios on which the prepayment information
compiled by HUD was based and the  anticipated composition of the Pools and  the
Mortgage Pools. The HUD data also did not include cooperative loans. The rate of
prepayment  for  cooperative loans  may  be higher  or  lower than  the  rate of
prepayment for conventional real  estate mortgage loans. The  HUD data is  based
entirely  on fixed-rate, level-payment mortgage loans  insured by the FHA, while
none of the Mortgage Loans will be so insured. Additionally, the Mortgage  Loans
will  be conventional mortgage  loans which have  historically prepaid at higher
rates than government insured mortgage loans, in part because, unlike government
insured mortgage  loans, such  mortgage loans  may include  due-on-sale  clauses
which  allow the holders of such mortgage loans to demand payment in full of the
remaining principal  balances  of  the  mortgage  loans  upon  sale  or  certain
transfers  of  the property  securing such  mortgage loans.  Moreover, published
information indicates that the rate  of prepayment with respect to  conventional
mortgage  loans has fluctuated significantly in recent years. Economic and other
conditions existing during the periods for which the HUD data was compiled  have
changed  significantly  and may  not be  applicable  now or  in the  future. For
instance,  published  information  indicates   that  the  prepayment  rate   for
conventional  mortgage loans  was substantially  lower during  the high interest
rate climate prevailing  during 1980, 1981  and early 1982  than the  prepayment
rate  indicated by the overall HUD data. In contrast, during 1986 and early 1987
there was a sharp decline in  long-term interest rates, and the prepayment  rate
for  conventional mortgage loans increased substantially. If interest rates fall
below the  Note Rates  on the  Mortgage Loans,  the rate  of prepayment  may  be
expected  to increase. For the foregoing  and other reasons, the Issuer believes
that no existing statistics of  which it is aware  provide a reliable basis  for
CitiCertificateholders  to  predict  the amounts  or  the timing  of  receipt of
prepayments on the Mortgage Loans.

    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."  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 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   such  refinancing,   either  pursuant   to  a
Consolidation Agreement or through the extension of a new loan to the  borrower,
the  refinanced Mortgage Loan will be treated  as fully prepaid and removed from
the Pool. The principal  balance of any such  refinanced Mortgage Loan  together
with  interest accrued thereon  at the applicable  Pass-Through Rate through the
last day of the month in which such refinancing occurred will be distributed  to
CitiCertificateholders  or holders  of the CitiMortgageCertificate,  as the case
may be, in the month following the refinancing.

exceed 5%) specified in  the applicable Prospectus  Supplement of the  aggregate
principal balance thereof as of the Cut-Off Date for the related Series.

ASSIGNMENT OF MORTGAGE LOANS

    At  the  time  of issuance  of  each  Series, the  affiliate  of  the Issuer
originating or acquiring the Mortgage Loans  in a Pool will assign the  Mortgage
Loans  to the Trustee, together  with all principal and  interest received on or
with respect to such Mortgage Loans after the first day of the month of issuance
of such CitiCertificates (the "Cut-Off Date") other than principal and  interest
due  and payable on or  before the Cut-Off Date. The  Trustee or its agent will,
concurrently with such assignment, authenticate and deliver the CitiCertificates
evidencing such Series in  exchange for the Mortgage  Loans. 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 will, as to each Real Estate Loan in
the 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.

    The Originators expect to record or  file 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. However, if any of
the Originators 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 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 were  commenced prior to  such recording or
filing, creditors  of  such Originator  may  be able  to  assert rights  in  the
affected Mortgage Loans superior to those of any 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

                                      A-9
<PAGE>
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  the
related Guaranty or other credit support and unreimbursed Voluntary Advances (as
described  below). Such repurchase will not  diminish the amount available under
the  related  Guaranty  or  other  credit   support  and  is  deemed  to  be   a
reimbursement.  Except  as  provided  in  the  next  sentence,  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  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 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  and
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 borrower'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 (as defined herein)) 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  for
the twelve months preceding the Cut-Off Date and there are not 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,

                                      A-10
<PAGE>
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 Corporation ("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  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.

    Each Trustee also will be authorized to appoint a custodian, 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. Any custodian will  keep such documents as  such 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"), 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.  The
only  initial Depository  will be  Citibank (New  York State),  unless otherwise
specified in the applicable Prospectus Supplement. 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  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 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 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 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 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 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

                                      A-11
<PAGE>
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 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 prior to any such downgrade.

    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 the 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,  respectively,  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 on the
business day next following the day of receipt and posting.

                                      A-12
<PAGE>
    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 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 (as  defined  below),
second from a Voluntary Advance and third, if necessary, from payments under the
credit  support,  (ii)  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 by the servicer 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
cannot  be covered by  an advance out  of cash in  the Certificate Account 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. 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, and  the
                           aggregate  amount  available  in  the  Certificate  Account,  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 Servicing
                           Compensation (exclusive of any amount designated as  "additional
                           servicing compensation" in the related Prospectus Supplement).
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.
</TABLE>

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

COLLECTION AND OTHER SERVICING PROCEDURES

    The Issuer  or the  Servicer will  make reasonable  efforts to  collect  all
payments  called for  under the  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 a  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.  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 a  Mortgage Loan  during  the
scheduled  period  in  accordance  with the  amortization  schedule  thereof and
without regard to the temporary modification thereof. (PA Section 3.01)

                                      A-14
<PAGE>
    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, 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 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.  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.

    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)

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 (i) the maximum insurable value of the
improvements securing such Real Estate Loan  or, as required by California  law,
the replacement value of the improvements or (ii) the principal balance owing on
such  Real  Estate Loan,  whichever is  less.  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. (PA Section 3.14).

    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,

                                      A-15
<PAGE>
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 the 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.

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  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

                                      A-16
<PAGE>
remaining  Amount Available under any credit support. (PA Section 3.16) 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. In  this regard,  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"  for a
description of  the limited  availability  of deficiency  judgments),  foreclose
against  such property  and proceed for  the deficiency  against the appropriate
person. 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 Internal Revenue Code of 1986, as amended
(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." 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 or  the
Servicer  or 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
(as  defined  in Code  Section 216(b)(2)).  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   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 the 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

                                      A-17
<PAGE>
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.  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  to  the Issuer  from  these
additional sources will be negligible in amount.

    The  Issuer or the Servicer will be  responsible (to the extent of Servicing
Compensation (exclusive  of  any  amount  designated  as  "additional  servicing
compensation"  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 below),  including,  without  limitation,  payment  of  the  fees  and
disbursements  of the Trustee and independent  accountants, payments of all fees
and expenses in connection with  the realization upon defaulted Mortgage  Loans,
payment  of expenses  incurred in connection  with distributions  and reports to
CitiCertificateholders.

    If no further amount is payable under  the 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.

<PAGE>
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  statutory  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.  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 and Connecticut.  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  a
financing

<PAGE>
statement  covering  the  proprietary  lease  or  occupancy  agreement  and  the
cooperative shares  is filed  in  the appropriate  state  and local  offices  to
perfect  the 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  corporate
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.  In
Texas,  for example, it is necessary to give both notice of intent to accelerate
as well as notice of acceleration of an installment note. 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.  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
uncommon  for a third  party to purchase  the property at  the foreclosure sale.
Rather, it is 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 making such repairs at its  own
expense  as are necessary to  render the property suitable  for sale. The lender
will commonly obtain the

                                      A-20
<PAGE>
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.

    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, 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 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.  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
the latter  it may  not. However,  because of  anti-deficiency legislation  with
respect  to  purchase-money  deeds of  trust,  the  Issuer will,  in  almost all
instances, pursue nonjudicial foreclosure. A second difference between  judicial
and  nonjudicial foreclosure is that  in the case of  the former the trustor may
redeem the property by paying the amount bid  at the sale for a period of  three
months  or one year after  the sale, depending upon  whether the proceeds of the
sale were sufficient to pay the lender  in full, and the purchaser at the  sale,
whether  it be  the lender  or a  third party,  may not  have possession  of the
property until expiration of the redemption period.

                                      A-21
<PAGE>
    Following the entry of  judgment in judicial foreclosure,  the clerk of  the
court  issues a  writ of  special execution  directing the  sheriff to  sell the
subject property  at  a  sheriff's  sale.  Following  the  sheriff's  sale,  the
mortgagor  has the right to redeem the property  by paying the amount bid at the
sheriff's sale plus statutory interest (a) if the property is both abandoned and
not used primarily for agricultural or  grazing purposes, within thirty days  of
the  date of the sheriff's sale,  or (b) if the property  is not abandoned or is
used primarily for agricultural or grazing purposes, within six months after the
date of  the  sheriff's sale.  If  the mortgagor  does  not redeem,  the  senior
creditor  having a  lien on the  property may redeem  within successive five-day
periods after the time allowed the  prior lienholder, according to the  priority
of liens.

    While  a lender may accept a deed in lieu of foreclosure instead of pursuing
either judicial or nonjudicial foreclosure, it  will be the Issuer's policy  not
to  do so.  By accepting  a deed in  lieu of  foreclosure, the  lender takes the
property back subject to all junior liens, which would be extinguished by either
judicial or nonjudicial foreclosure. Even when it can be verified that there are
no junior liens of record,  it is not advantageous to  accept a deed in lieu  of
foreclosure  because the trustor or another  creditor can challenge the transfer
to the lender, either  in bankruptcy court  or in state  court, as a  fraudulent
conveyance  if the property  was worth more  than the amount  of the debt. Title
companies usually will not insure against this risk.(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. 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  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 foreclosures. 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.

    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  cancelled 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
- ------------------------
(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.

                                      A-22

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.

    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.

    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

                                      A-23
<PAGE>
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.

    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 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.

    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  thirty
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

                                      A-24
<PAGE>
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 2  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 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
amount  bid for the mortgaged property at  the foreclosure sale is less than the
debt, 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. 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.

    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 collateral
and/or enforce  a deficiency  judgment.  For example,  with respect  to  federal
bankruptcy  law, the filing of a petition acts as a stay against the enforcement
of remedies for collection of a debt. Moreover, a court with federal  bankruptcy
jurisdiction  may permit a  debtor through his or  her Chapter 13 rehabilitative
plan to cure a monetary  default with respect to a  mortgage loan on a  debtor's
residence  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 sale of the

                                      A-25
<PAGE>
property had  yet occurred)  prior to  the  filing of  the debtor's  Chapter  13
petition.  Some courts with federal bankruptcy jurisdiction have approved plans,
based on the  particular facts  of the  reorganization case,  that effected  the
curing of a mortgage loan default by paying arrearages over a number of years.

    Courts  with federal  bankruptcy jurisdiction  have also  indicated that the
terms of a mortgage loan  secured by property of the  debtor may be modified  if
the  borrower has filed a petition under Chapter 11. These courts have suggested
that 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  residence, thus  leaving  the
lender  a general unsecured creditor for the difference between the value of the
residence and  the outstanding  balance of  the loan.  Most borrowers,  however,
choose  to  file either  under Chapter  7,  in which  the borrower's  assets are
liquidated, or under Chapter 13, in  which the borrower's debts are adjusted  to
allow  him or  her to repay  them over  a period of  three to  five years. Under
Chapter 13, the terms  of a mortgage  loan secured by property  that is not  the
principal  residence  of  the  debtor  may  be  modified.  Courts  with  federal
bankruptcy jurisdiction  have  suggested  that such  modifications  may  include
reducing  the amount of each monthly payment,  changing the rate of interest and
altering the repayment  schedule, thus  leaving the lender  a general  unsecured
creditor  for  the  difference  between  the  value  of  the  residence  and the
outstanding balance  of  the loan.  Federal  bankruptcy law  and  United  States
Supreme  Court decisions indicate that the  foregoing modifications could not be
applied to  the terms  of  a loan  secured by  property  that is  the  principal
residence  of the debtor. Courts similarly may be  able to modify the terms of a
Cooperative Loan, but to our knowledge no case law exists on this point. In  all
cases,  the  secured creditor  is entitled  to  the value  of its  security plus
post-petition interest, attorneys' fees and costs to the extent the value of the
security exceeds the debt.

    The Code  provides  priority to  certain  tax liens  over  the lien  of  the
mortgage.  This  may  have  the  effect  of  delaying  or  interfering  with the
enforcement of rights  in respect  of a  defaulted mortgage  loan. In  addition,
substantive  requirements are imposed  upon mortgage lenders  in connection with
the origination and the servicing of mortgage loans by numerous federal and some
state consumer protection  laws. The laws  include the federal  Truth-in-Lending
Act,  Real Estate Settlement Procedures Act,  Equal Credit Opportunity Act, Fair
Credit Billing  Act, Fair  Credit  Reporting Act,  and related  statutes.  These
federal  laws impose specific  statutory liabilities upon  lenders who originate
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.

                                      A-26

    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 or not
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  or
not 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.

<PAGE>
    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 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

                                      A-28
<PAGE>
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.

                                                                      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 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  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 with no limitations
as to amount.

GNMA CERTIFICATES

    All  of  the  GNMA  Certificates  will  be  "fully  modified   pass-through"
mortgage-backed   certificates  issued  and  serviced  by  issuers  approved  by
GNMA--approved issuers.  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 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 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.

                                      B-3

    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. 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  Goup 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"  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 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.

    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

                                      B-5
<PAGE>
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" 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.
