(1) The Class A-2 CitiCertificates will accrue interest for the initial LIBOR 
    Accrual Period at the rate of 5.975% per annum and, for each LIBOR Accrual
    Period thereafter, at the per annum rate equal to LIBOR plus 0.60%, 
    determined monthly as provided herein, subject to a maximum Stated Rate of
    9.00% per annum and a minimum Stated Rate of 0.60% per annum.

(2) The Class A-3 CitiCertificates have no Stated Amount. The Class A-3 Notional
    Amount on any Distribution Date will be equal to the Class A-2 Stated Amount
    on such date, and initially will equal the Initial Stated Amount of the 
    Class A-2 CitiCertificates.

(3) The Class  A-3  CitiCertificates  will  accrue  interest  for the
    initial LIBOR Accrual Period at the rate of 3.025% per annum and,
    for each LIBOR Accrual Period  thereafter,  at the per annum rate
    on the Class A-3  Notional  Amount  equal to 8.40%  minus  LIBOR,
    determined  monthly  as  provided  herein,  subject  to a minimum
    Stated Rate of 0.00%.

(4) The Class A-9 CitiCertificates are principal only regular interests and do 
    not bear interest.

(5) The Class A-IO Certificates will accrue interest for each Standard Accrual 
    Period in an amount equal to the Class A-IO Interest Amount.

(6) The last scheduled distribution date is the "latest possible maturity date"
    of the related Subclass or Class for purposes of Section 860G(a)(1) of the 
    Code and Treasury Regulations Section 1.860G-1(a)(4)(iii).

          The  Residual  Certificates  will not be issued  with  Initial  Stated
Amounts or Stated Rates, but will be entitled to distributions to the extent set
forth herein.

          Interest will accrue with respect to a Distribution  Date on the Class
A (other than the Class A-2 and Class A-3), Class M and Class B CitiCertificates
and the Class A-IO  Certificates  during the related Standard Accrual Period and
on the Class A-2 and Class A-3 CitiCertificates during the related LIBOR Accrual
Period.

          The Class A-9 CitiCertificates are principal only CitiCertificates and
do not bear interest.

                                       3
<PAGE>

          (b) Each of the Class A, Class M  CitiCertificates  and Class B
CitiCertificates  and the Class L Regular  Interest  will bear interest on their
respective  Stated Amounts (and, in the case of the Class A-3  CitiCertificates,
on the  Class  A-3  Notional  Amount)  at the  applicable  Stated  Rate for such
Subclass or Class set forth or described in Section  12.01(a).  Interest accrued
on the CitiCertificates  (other than the LIBOR CitiCertificates) and the Class L
Regular  Interest  during any Standard  Accrual Period will be calculated on the
assumption   that   distributions   in  reduction   of  Stated   Amount  on  all
CitiCertificates  and  the  Class  L  Regular  Interest  then  entitled  to such
distributions  were  made and  allocations  of any  losses  were made on the day
immediately following the last day of the preceding Standard Accrual Period, and
not on the following  Distribution  Date when  actually made or allocated.  Each
Class A Subclass  Interest Amount,  each Class B Subclass  Interest Amount,  the
Class M  Interest  Amount  and the Class  A-IO  Interest  Amount  relating  to a
Standard  or LIBOR  Accrual  Period  shall  be  distributable  on the  following
Distribution  Date or, if such day is not a Business Day, on the next succeeding
Business  Day.  Each  Subclass  and Class of  CitiCertificates,  the Class  A-IO
Certificates  and the Class L Regular  Interest  shall accrue  interest from the
applicable  Accrual Date for such  Subclass and Class of  CitiCertificates,  the
Class A-IO Certificates and the Class L Regular Interest.

          On each  Distribution  Date, each Class A Subclass Interest Amount and
each Class B Subclass  Interest  Amount for such  Subclass  with respect to such
Distribution  Date shall be distributable to such Subclass of  CitiCertificates,
and the Class A-IO Interest  Amount and the Class M Interest Amount with respect
to such  Distribution Date shall be distributable to the Class A-IO Certificates
and  the  Class  M  CitiCertificates,  respectively.  In  the  event  that  on a
particular Distribution Date the Pool Distribution Amount is insufficient to pay
any of the Class A  Subclass  Interest  Amounts,  the  Distributable  Class A-IO
Interest  Amount,  the Class M  Interest  Amount or any of the Class B  Subclass
Interest Amounts,  the aggregate amount of the shortfall will be carried forward
and added pro rata to the amount  distributable  to  holders  of the  applicable
Subclass of Class A or Class B CitiCertificates  or the Class M CitiCertificates
or the Class A-IO Certificates,  as applicable,  until  distribution  thereof is
made as provided herein.  On each  Distribution  Date,  interest on each Class L
Regular Interest shall be distributable as provided in Section 13.03.

          With respect to any LIBOR  Accrual  Period  commencing on or after the
first  Distribution Date, the determination of LIBOR shall be made in accordance
with the following provisions:

               (i) On each LIBOR  Determination Date, the Trustee will determine
            LIBOR  on the  basis  of LIBOR  quotations  provided  by each of the
            Reference Banks as of approximately  11:00 a.m. (London time) on the
            LIBOR  Determination Date in question,  as such quotations appear on
            the  Reuters  Screen  LIBO Page or the  Telerate  Page 3750 (each as
            defined by reference to the International Swap Dealers  Association,
            Inc. 1991 ISDA Definitions).

               (ii) If, on any LIBOR  Determination Date, at least two Reference
            Banks  provide   quotations,   LIBOR  shall  be  determined  as  the
            arithmetic  mean of such  offered  quotations  (rounded  upward,  if
            necessary, to the nearest multiple of 1/16 of 1%).

               (iii) If, on any LIBOR  Determination  Date,  only one or none of
            the Reference Banks provides  quotations,  LIBOR shall be the higher
            of:

                     (x) LIBOR as determined on the previous LIBOR Determination
                  Date or, in the case of the first LIBOR Determination Date, 
                  5.375%; or

                     (y) the Reserve Rate.  The Reserve Rate shall be the rate
                  per annum  (rounded  upward,  if  necessary,  to the nearest
                  multiple  of 1/16 of 1%) that the Trustee  determines  to be
                  either (1) the  arithmetic  mean of the  offered  quotations
                  that the  leading  banks in New York  City  selected  by the
                  Trustee  (after  consultation  with CMSI) are quoting on the
                  relevant LIBOR

                  Determination Date for one-month United States dollar deposits
                  to the principal  London office of each of the Reference Banks
                  or those of them  (being at least two in number) to which such
                  offered  quotations are, in the opinion of the Trustee,  being
                  so made or (2) in the event that the Trustee can  determine no
                  such  arithmetic  mean,  the  arithmetic  mean of the  offered
                  quotations that leading banks in New York City selected by the
                  Trustee  (after  consultation  with CMSI) are  quoting on such
                  LIBOR   Determination  Date  to  leading  European  banks  for
                  one-month  United States dollar deposits;  provided,  however,
                  that if the banks  selected  by the Trustee are not quoting as
                  mentioned above, LIBOR for the next LIBOR Accrual Period shall
                  be LIBOR as specified in (i) above.

               (c) Except as  provided  below and subject to the  provisions  of
Section  13.01,  on each  Distribution  Date the Class A Principal  Distribution
Amount will be applied to the  distribution in reduction of Stated Amount of the
Subclasses of the Class A  CitiCertificates  in the following  order of priority
after giving effect to any reduction of the Stated  Amount  thereof  pursuant to
Section 13.02:

               (A) to the  Class  A-9  CitiCertificates  in an  amount up to the
Class A PO Principal Amount, until the Stated Amount thereof has been reduced to
zero,

               (B)  concurrently,  (x)  an  amount  up to  the  Group  I  Non-PO
Principal Amount shall be allocated:

               First, to the Class A-1 and Class A-2 CitiCertificates,  pro rata
on the basis of their respective Class A Subclass Stated Amounts until each such
Class A Subclass Stated Amount has been reduced to zero,

               Second, to the Class A-4 CitiCertificates until the Stated Amount
thereof has been reduced to zero, and

               Third,  concurrently,  (i)79.9494702223%  first to the  Class A-7
CitiCertificates  until the Stated Amount  thereof has been reduced to zero, and
then to the Class A-8 CitiCertificates  until the Stated Amount thereof has been
reduced to zero, and (ii) 20.0505297777% to the Class A-5 CitiCertificates until
the Stated Amount has been reduced to zero.

               (y) the Group II Non-PO  Principal  Amount  shall be allocated to
the Class A-6 CitiCertificates  until the Stated Amount thereof has been reduced
to zero.

               (d) On each  Distribution  Date,  Available PO Loss Funds will be
allocated  to the Class A-9  CitiCertificates  in  respect of any Unpaid PO Loss
Amounts.

               On any Distribution Date on or after the Subordination  Depletion
Date  notwithstanding  the priorities of Section  12.01(c),  funds available for
distribution in reduction of Stated Amount of the Class A CitiCertificates  will
be  distributed  to the  Class A  CitiCertificates  (other  than the  Class  A-9
CitiCertificates),  on the one hand, and the Class A-9 CitiCertificates,  on the
other,  pro  rata on the  basis of (i) the sum of the  Group I Non-PO  Principal
Amount  and the  Group II  Non-PO  Principal  Amount  and  (ii)  the  Class A PO
Principal  Amount,  respectively.  On each  Distribution  Date on and  after the
Subordination   Depletion   Date,   the   amount   allocated   to  the  Class  A
CitiCertificates  (other than the Class A-9 CitiCertificates)  will be allocated
pro  rata,   based  on   outstanding   Stated   Amounts,   among  such  Class  A
CitiCertificates   notwithstanding   the   priorities   set  forth  in   Section
12.01(c)(B).  The amount  allocated to each Class A Subclass will be distributed
pro rata among the holders of CitiCertificates of such Class A Subclass.

<PAGE>

               On each Distribution  Date,  subject to the provisions of Section
13.01, a  distribution  in reduction of the Stated Amount of the Class L Regular

Stated Amount of the Class A-2 CitiCertificates.

               On each Distribution  Date,  subject to the provisions of Section
13.01,   distributions   in   reduction   of  Stated   Amount  of  the  Class  M
CitiCertificates and the Subclasses of Class B CitiCertificates  will be made in
an aggregate amount equal to the Class M Principal  Distribution  Amount and the
Class B Principal  Distribution  Amount,  respectively,  in accordance  with the

                Section 13.02. Allocation of Realized Losses; Recoveries .

                (a)  With  respect  to  any  Distribution  Date,  prior  to  the
Subordination  Depletion Date, the applicable Non-PO Percentage of the principal
portion of Realized Losses (other than Debt Service  Reductions,  Excess Special
Hazard  Losses,  Excess  Fraud  Losses and  Excess  Bankruptcy  Losses)  will be
allocated as follows:

                first,  to the Class B-5  CitiCertificates  until  their Class B
Subclass Stated Amount has been reduced to zero;

                                       22
<PAGE>

                second,  to the Class B-4  CitiCertificates  until their Class B
Subclass Stated Amount has been reduced to zero;

                third,  to the Class B-3  CitiCertificates  until  their Class B
Subclass Stated Amount has been reduced to zero;

                fourth,  to the Class B-2  CitiCertificates  until their Class B
Subclass Stated Amount has been reduced to zero;

                fifth,  to the Class B-1  CitiCertificates  until  their Class B
Subclass Stated Amount has been reduced to zero; and

                sixth, to the Class M CitiCertificates until their Stated Amount
has been reduced to zero.

                With  respect  to  any  Distribution  Date,  the  applicable  PO
Percentage  of such losses will be allocated  to the Stated  Amount of the Class
A-9 CitiCertificates.

                With  respect  to  any   Distribution   Date  on  or  after  the
Subordination  Depletion Date, the applicable  Non-PO  Percentage of such losses
will be  allocated  to the Class A  CitiCertificates  (other  than the Class A-9
CitiCertificates),  pro  rata  among  such  Subclasses  on the  basis  of  their
respective Class A Subclass Stated Amounts.

                This allocation of Realized Losses will be effected  through the
reduction of the applicable Subclass Stated Amount.

                Losses and  delinquencies  resulting from  Extraordinary  Events
will be allocated in the same manner as Excess  Special  Hazard  Losses,  Excess
Fraud Losses and Excess Bankruptcy Losses as set forth in Section 13.02(b).

                (b) The  principal  portion  of Excess  Special  Hazard  Losses,
Excess Fraud Losses and Excess  Bankruptcy Losses shall be allocated as follows:
The  applicable PO Percentage of such Realized  Losses shall be allocated to the
Class A-9 CitiCertificates and the applicable Non-PO Percentage of such Realized
Losses  shall be  allocated  on a pro rata  basis  among the Class A  Subclasses
(other than the Class A-9 CitiCertificates),  Class M CitiCertificates and Class
B Subclasses based on the Stated Amount of each such Subclass or Class, prior to
giving  effect to  distributions  in reduction of Stated  Amount on the relevant
Distribution Date.

                (c) Any  Realized  Losses  allocated to a Subclass of Class A or
Class B  CitiCertificates  or the Class M  CitiCertificates  pursuant to Section
13.02(a) or Section  13.02(b) shall be allocated among the  CitiCertificates  of
such Subclass or Class based on their respective Stated Amounts.

                (d) In the  event  that  there is a  recovery  of an  amount  in
respect of principal  which had previously  been allocated as a Realized Loss to
any  one  or  more  Subclasses  of  Class  A   CitiCertificates,   the  Class  M
CitiCertificates or any one or more Subclasses of Class B CitiCertificates,  the
amount of such recovery shall be distributed to the Class A CitiCertificates  in
the same manner as such loss was allocated to such Class A Subclass, but only if
and to the extent the Class A  CitiCertificates  had theretofore  been allocated
any  Realized  Losses in  respect  of  principal.  The  amount of such  recovery
allocated   to  the  Class  A   CitiCertificates   (other  than  the  Class  A-9
CitiCertificates)  is referred to as the  "Reimbursable  Class A Non-PO Losses".
The  amount  of  such  recovery  allocated  to the  Class  A-9  CitiCertificates
(exclusive of amounts in respect of such a Realized Loss previously  distributed
in respect of the Class A-9  CitiCertificates as reimbursement of Unpaid PO Loss
Amounts)

                                       23
<PAGE>

is referred to as the "Reimbursable Class A PO Losses".  Any remaining amount of
any such recovery shall be distributed to the Class M CitiCertificates  but only
if and to the extent  that the Class M  CitiCertificates  had  theretofore  been
allocated any Realized Losses ("Reimbursable Class M Losses"), then to the Class
B-1  CitiCertificates  but  only  if  and to  the  extent  that  the  Class  B-1
CitiCertificates  had theretofore been allocated any Realized Losses and then to
the Class  B-2,  Class  B-3,  Class B-4 and Class B-5  CitiCertificates  in like
manner (collectively, the "Reimbursable Class B Losses"). A Subclass or Class of
CitiCertificates  that is no longer  outstanding  shall not be  entitled  to any
share of any such recovery.

                (e) The interest portion of Excess Special Hazard Losses, Excess
Fraud Losses and Excess  Bankruptcy  Losses  shall be allocated  proportionately
between the  CitiCertificates  and the Class A-IO Certificates  based on (in the
case of the  CitiCertificates)  the sum of (i) the  interest  accrued at the Net
Note Rate of the Discount Mortgage Loans and (ii) the product of 7.50% per annum
and the aggregate  Adjusted  Balance of the Premium  Mortgage  Loans and (in the
case of Class A-IO  Certificates) the Class A-IO Interest Amount,  and among the
Class A,  Class M and Class B  CitiCertificates,  pro rata  based on the Class A
Interest  Amount,  the Class M Interest Amount and the Class B Interest  Amount.
Any such loss allocated to the Class A CitiCertificates shall be allocated among
the outstanding  Subclasses of Class A  CitiCertificates  based on their Class A
Subclass  Interest  Percentages.   Any  such  loss  allocated  to  the  Class  B
CitiCertificates will be allocated between the outstanding Subclasses of Class B
CitiCertificates based on their Class B Subclass Interest Percentages. After the
Subordination  Depletion  Date, the interest  portion of Realized Losses will be
allocated among the outstanding  Subclasses of Class A CitiCertificates  and the
Class A-IO  Certificates as described above. The amount of such losses allocated
to the Class A-IO  Certificates  will reduce the Class A-IO Interest  Amount for
such Distribution Date.

                (f) Realized  Losses  allocated in accordance  with this Section
13.02 will be  allocated on the  Distribution  Date in the month  following  the
month in which such loss was incurred and, in the case of the principal  portion
thereof,  (x) in the case of Excess Special  Hazard Losses,  Excess Fraud Losses
and Excess Bankruptcy Losses, prior to giving effect to distributions made under
Section  13.01  on  such  Distribution  Date  and (y) in the  case of all  other
Realized Losses, giving effect to distributions made under Section 13.01 on such
Distribution Date.

                (g)  On  each  Distribution  Date  occurring  subsequent  to the
Subordination  Depletion  Date, the interest  portion of Realized Losses and the
interest portion of Remittance  Delinquencies not covered by Voluntary Advances,
Trustee Advances,  Advance Account Advances or Certificate Account Advances with
respect  to such  Distribution  Date  will be  allocated  pro rata  between  the
CitiCertificates  and the Class A-IO  Certificates.  The pro rata  allocation of
such losses and delinquencies between the Class A CitiCertificates and the Class
A-IO  Certificates  will be made  in the  same  manner  as  Prepayment  Interest
Shortfalls  are  allocated  between  the  CitiCertificates  and the  Class  A-IO
Certificates.  The amount allocated to the Class A-IO  Certificates  will reduce
the Distributable Class A-IO Interest Amount for such Distribution Date.

                Section  13.03.   Class  L  Regular  Interest   Allocations  and
Distributions.

                (a) On each  Distribution  Date,  the Class L  Regular  Interest
shall  receive a  distribution  in  respect  of  principal  equal to the  amount
distributed in reduction of Stated Amount of the Class A-2 CitiCertificates.

                As of any  date,  the  Stated  Amount  of the  Class  L  Regular
Interest will equal the Stated Amount of the Class A-2 CitiCertificates.

                On each  Distribution  Date, the Class L Regular  Interest shall
receive a distribution in respect of interest equal to the amount distributed in
respect of interest to the Class A-2 and Class A-3 CitiCertificates.

                                       24
<PAGE>

                (b) With respect to any Distribution Date, the principal portion
of Realized Losses and recoveries  attributable to previously allocated Realized
Losses will be allocated  to the Class L Regular  Interest in an amount equal to
the amount allocated to the Class A-2 CitiCertificates.

                With respect to any  Distribution  Date, the interest portion of
Realized  Losses will be allocated  to the Class L Regular  Interest in the same
manner as interest is allocated to such Class L Regular Interest.

                (c) No interest shortfall amount or unpaid interest shortfall on
the Class L Regular Interest will bear interest.

                (d) The  Distribution  Date  Statement  prepared by the Servicer
pursuant to Section 3.03(f) shall include the following additional information:

                 (i) the  distributions  of principal in reduction of the Stated
             Amount of the Class L Regular Interest and the Stated Amount of the
             Class L Regular Interest that will remain  outstanding after giving
             effect to such distribution;

                 (ii) the  amount of  interest  that has  accrued on the Class L
             Regular Interest and any Non-Supported Interest Shortfall allocated
             thereto;

                 (iii) the amount of interest to be distributed on the Class L 
             Regular Interest;

                 (iv) the  amount of the  principal  portion  of Excess  Special
             Hazard  Losses,  Excess Fraud Losses and Excess  Bankruptcy  Losses
             allocable to the Class L Regular Interest; and

                 (v) the  interest  portion of Excess  Special  Hazard  Losses,
             Excess Fraud Losses and Excess Bankruptcy Losses allocable to the
             Class L Regular Interest.

         Section  13.04  Distributions  on the  Residual  Certificates  . Upon a
termination  of the  Trust  in  accordance  with  Section  9.01,  the  Class  LR
Certificate shall receive all amounts  remaining in the Certificate  Account and
the Class R Certificate  shall receive any amounts  remaining in the  Upper-Tier
REMIC  Account after all required  distributions  on the  CitiCertificates,  the
Class A-IO Certificates and the Class L Regular Interest have been made.

(including  servicing  fees with  respect  thereto) of a type not required to be
deposited therein as specified in Article XI or Article XII.

         (c)  In  instances  where  an  original  recorded  Mortgage  cannot  be
delivered by CMSI to the Trustee prior to or concurrently with the execution and
delivery of this  Agreement,  due to a delay in connection with the recording of
such  Mortgage,  CMSI may,  (a) in lieu of  delivering  such  original  recorded
Mortgage referred to in clause (a)(ii) or (b)(ii) above,  deliver to the Trustee
a copy thereof, provided that CMSI certifies that the original Mortgage has been
delivered to a title  insurance  company for  recordation  after  receipt of its
policy  of title

                                       39
<PAGE>

insurance or binder  therefor  (which may be a certificate  relating to a master
policy  of  title  insurance),  and  (b) in  lieu of  delivering  the  completed
assignment  in  recordable  form  referred  to in clause  (a)(iv) or (b)(ii) and
(b)(ix) above to the Trustee,  deliver such assignment to the Trustee  completed
except for recording information.  In all such instances,  CMSI will deliver the
original  recorded  Mortgage and completed  assignment  (if  applicable)  to the
Trustee  promptly upon receipt of such Mortgage.  In instances where an original
recorded  Mortgage  has  been  lost  or  misplaced,  CMSI or the  related  title
insurance company may deliver, in lieu of such Mortgage, a copy of such Mortgage
bearing recordation  information and certified as true and correct by the office
in which recordation thereof was made. In instances where the original or a copy
of the title insurance policy referred to in clause (a)(v) above (which may be a
certificate  relating to a master policy of title  insurance)  pertaining to the
Mortgaged  Property  relating to a Mortgage  Loan cannot be delivered by CMSI to
the Trustee  prior to or  concurrently  with the  execution and delivery of this
Agreement  because  such  policy  is not yet  available,  CMSI  may.  in lieu of
delivering the original or a copy of such title insurance  referred to in clause
(a)(v) above, deliver to the Trustee a binder with respect to such policy (which
may be a certificate relating to a master policy of title insurance) and deliver
the original or a copy of such policy (which may be a certificate  relating to a
master policy of title  insurance) to the Trustee when  available,  In instances
where     an     original     assumption,      modification,      buydown     or
conversion-to-fixed-interest-rate  agreement  cannot be delivered by CMSI to the
Trustee  prior  to or  concurrently  with the  execution  and  delivery  of this
Agreement,  CMSI may,  in lieu of  delivering  the  original  of such  agreement
referred  to in clause  (a)(iii)  or (b)(iii)  above,  deliver a certified  copy
thereof  CMSI will  deliver the original  assumption,  modification,  buydown or
conversion-to-fixed-interest-rate agreement to the Trustee promptly upon receipt
thereof

         CMSI agrees,  at its own  expense,  to prepare and record (or to supply
the Trustee with  evidence of  recordation  of) each  assignment  referred to in
clause  (a)(vi) or (b)(vi) and (b)(ix)  above.  CMSI shall prepare and deliver a
copy of each such assignment to the Trustee as soon as practicable but not later
than 60 days after the date of initial  issuance  of the  CitiCertificates,  and
CMSI intends to effect such recordation as soon as practicable thereafter in the
appropriate  public office for real property  records  except that CMSI need not
cause to be recorded any  assignment  which relates to a Mortgage Loan for which
the Mortgaged  Property is located in a jurisdiction under the laws of which, on
the basis of an Opinion of Counsel  delivered to the Trustee which is reasonably
satisfactory to the Trustee,  recordation of such assignment is not necessary to
protect the Trustee and the Certificateholders' interest in the related Mortgage
Loan or Mortgage.

         CMSI  agrees,  at its  own  expense,  to  record  any  UCC-3  financing
statements not  previously  recorded (and to supply the Trustee with evidence of
such  recordation).   CMSI  intends  to  effect  such  recordation  as  soon  as
practicable  after the date of initial issuance of the  CitiCertificates  in the
appropriate public office.

         In the case of Mortgage Loans which have been prepaid in full after the
Cut-Off Date and prior to the date of execution and delivery of this  Agreement,
CMSI,  in lieu of  delivering  the  above  documents  to the  Trustee,  herewith
delivers to the Trustee a certification  of a Servicing  Officer as set forth in
Section 3.22

         In  connection  with such  transfer  and delivery of the balance of the
Trust  Fund,  CMSI,  concurrently  with  the  execution  and  delivery  of  this
Agreement,  shall  deposit into the  Certificate  Account cash in the amount (if
any) specified in Article XII.

         Section  2.02.  Acceptance  by Trustee.  The Trustee,  by execution and
delivery hereof,  acknowledges  receipt,  subject to the review described in the
succeeding sentence,  of the documents and other property referred to in Section
2.01 and declares that the Trustee holds and will hold such  documents and other
property,  including  property  yet to be received in the Trust Fund,  in trust,
upon the trusts  herein set forth,  for the  benefit of all  present  and future
Certificateholders.    The   Trustee   agrees,   for   the   benefit   of   such
Certificateholders,  to review each Mortgage File within 90 days after execution
and delivery of this  Agreement,  to ascertain that all required  documents have
been executed,  received and recorded,  if  applicable,  and that such documents
relate to the

                                       40
<PAGE>

Mortgage  Loans  identified  in Exhibit B-1 and B-2 hereto.  If in the course of
such review the Trustee finds a document or documents  constituting  a part of a
Mortgage  File to be  defective  in any  material  respect,  the  Trustee  shall
promptly so notify CMSI,  whereupon  CMSI shall have a period of 180 days within
which to  correct  or cure  any such  defect  (including  correction  or cure by
substitution of Mortgage Loans to the extent  permitted by Section 2.04). If any
such material defect has not been corrected or cured,  CMSI will, not later than
180 days after the  Trustees  notice  respecting  such  defect,  repurchase  the
related  Mortgage  Loan  from the  Trustee  at a price  equal to (I) 100% of the
Adjusted  Balance on such Mortgage Loan, after taking into account any principal
payable  thereon on the Due Date in the month of  repurchase,  plus (ii) accrued
and unpaid  interest  thereon at the Mortgage  Note Rate less in the case of the
CitiMae Mortgage Loan, the applicable Expense Rate and the Retained Fixed Yield,
if any, to the first day of the month in which  proceeds of such  repurchase are
distributed to the Certificateholders, plus (iii) any unreimbursed payments with
respect to such Mortgage Loan, to the extent not covered in (ii) above,  as part
of a  Voluntary  Advance,  a  Trustee  Advance  or an  Advance  Account  Advance
whereupon all Voluntary Advances,  Trustee Advances and Advance Account Advances
will be reimbursed to the Trustee or deemed  reimbursed to CMSI, as the case may
be,  with  respect  to  such   Mortgage   Loan  by  such   respective   amounts.
Notwithstanding  the preceding two sentences,  any material defect that causes a
Mortgage Loan to fail to constitute a "qualified mortgage" within the meaning of
Code Section  860G(a)(3)  shall either be corrected or cured by CMSI or, failing
such correction or cure,  CMSI shall  repurchase such Mortgage Loan at the price
described in the preceding sentence (or, if within two years of the Startup Day,
or such other period as may be permitted by the REMIC Provisions,  substitute an
Eligible  Substitute  Mortgage Loan therefor  pursuant to Section 2.04) no later
than 90 days after the discovery of such material  defect.  Any such  repurchase
shall be  considered a prepayment in full of such Mortgage Loan on such Due Date
and shall be deposited (net of reimbursed  Voluntary Advances,  Trustee Advances
and Advance  Account  Advances) by CMSI in the  Certificate  Account  and,  upon
receipt by the  Trustee of written  notification  of such  deposit  signed by an
Authorized  Officer of CMSI,  the  Trustee  shall  release  to CMSI the  related
Mortgage  File and shall  execute and deliver  such  instruments  of transfer or
assignment,  in each case without recourse, as CMSI shall reasonably request, to
vest in CMSI any Mortgage Low released  pursuant hereto.  Any repurchase by CMSI
of a Mortgage Loan hereunder shall be deemed to include the right to receive any
Remittance thereon payable after the month of repurchase, and the Trustee shall,
upon  receipt  of any  such  Remittance,  promptly  remit  the  amount  of  such
Remittance to CMSI. It is understood  and agreed that the  obligation of CMSI to
repurchase any Mortgage Loan or make a substitution therefor pursuant to Section
2.04 as to which a  material  defect  in a  constituent  document  exists  shall
constitute the sole remedy against CMSI with respect to such defect available to
the Certificateholders or the Trustee on behalf of the Certificateholders.

         The Trustee may, concurrently with the execution and delivery hereof or
at any time  thereafter,  enter into a  Mortgage  Document  Custodial  Agreement
substantially  in the form of  Exhibit C hereto  pursuant  to which the  Trustee
appoints a Mortgage Document  Custodian to hold the Mortgage  Documents in trust
for the  Trustee  and the  benefit of the  Trustee  and all  present  and future
Certificateholders, which may provide that the Mortgage Document Custodian shall
conduct the review of each Mortgage File required  under the first  paragraph of
this  Section  2.02,  provided  that,  if the  Mortgage  Document  Custodian  so
appointed  is CMSI or an  Affiliate  of CMSI,  the Trustee  shall  conduct  such
review.

         Section 2.03.  Representations  and  Warranties  of CMSI.  CMSI hereby
represents and warrants to the Trustee that:

                 (i) The  information set forth in Exhibit B hereto was true and
correct in all material  respects as of the date or dates  respecting which such
information is furnished;

                 (ii) As of the Issue Date,  each Mortgage will be 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  as limited in clause (vi)
below, (b) covenants, conditions and restrictions,  rights of way, easements and
other  matters of

                                       41
<PAGE>

public  record as of the date of recording  of such  Mortgage,  such  exceptions
appearing of record being acceptable to mortgage lending institutions  generally
or  specifically  reflected in the  appraisal  obtained in  connection  with the
origination  of the  related  Mortgage  Loan,  (c) other  matters  to which like
properties  are  commonly  subject  which  do not in  the  aggregate  materially
interfere  with the  benefits  of the  security  intended to be provided by such
Mortgage  and (d) in  addition,  in the  case  of a  Mortgage  on a  cooperative
apartment  in a  cooperative  housing  corporation,  the  right  of the  related
cooperative to cancel the related shares and terminate the proprietary lease for
unpaid assessments (general and special) owed by the Mortgagor;

                 (iii)  Immediately  prior to the transfer of the Mortgage Loans
to the  Trustee,  CMSI has good title to, and is the sole legal  owner of,  each
Mortgage Loan (except as set forth in clause (v) below) and immediately upon the
transfer  and  assignment  herein  contemplated,  CMSI will have taken all steps
necessary  so that the  Trustee  will have good  title to,  and will be the sole
legal owner of, each Mortgage Loan (except as set forth in clause (v) below);

                 (iv) As of the  Cut-Off  Date,  no payment of  principal  of or
interest on or in respect of any  Mortgage  Loan was 30 days or more past due (a
Mortgage  Loan being  considered  30 days past due in a given month when payment
due on the first day of the prior month has riot been made on or before the last
day of such prior month) or has been 30 days or more past due more than once for
the twelve months preceding the Cut-Off Date;

                 (v) As of the Issue Date,  there is no mechanics' lien or claim
for work, labor or material affecting the premises subject to any Mortgage which
is or may be a lien prior to, or equal with,  the lien of such  Mortgage  except
those which are insured against by the title insurance policy referred to in (x)
below;

                 (vi)  As of the  Issue  Date,  there  is no  delinquent  tax or
assessment lien against any Mortgaged Property;

                 (vii) As of the Issue Date,  there is no valid offset,  defense
or  counterclaim  to any Mortgage Note or Mortgage,  including the obligation of
the Mortgagor to pay the unpaid principal and interest on such Mortgage Note;

                 (viii) As of the Issue Date, each Mortgaged Property is free of
material damage and is in good repair;

                 (ix) Each  Mortgage at the time it was  originated  complied in
all material respects with applicable state and federal laws, including, without
limitation, usury, equal credit opportunity, recording and disclosure laws;

                 (x) A lender's  title  insurance  policy or binder (which shall
have been  approved as such by either FNMA or the FHLMC) or other  assurance  of
title customary in the relevant jurisdiction therefor, was issued on the date of
the  origination of each Mortgage Loan (other than a Mortgage Loan relating to a
cooperative  apartment),  and, as of the Issue Date, each such policy, binder or
assurance is valid and remains in full force and effect;

                 (xi) The Mortgage  Loans conform in all material  respects with
the  descriptions  thereof  in the  Prospectus  and  the  Prospectus  Supplement
relating to the Certificates;

                 (xii) Each  Mortgage Loan having an original  principal  amount
exceeding 90% of its Original Value is covered by primary mortgage  insurance at
least until the  outstanding  principal  amount thereof is less than or equal to
80% of either the Original Value through principal  payments by the Mortgagor or
the value

                                       42
<PAGE>

thereof as determined by a new appraisal delivered subsequent to origination. So
long as it is in  effect,  such  primary  mortgage  insurance  covers the losses
arising  from  defaults  in an amount  equal to the excess,  of the  outstanding
principal  amount of such Mortgage  Loan over 75% of the Original  Value of such
Mortgage Loan;

                 (xiii) The original  principal amount of each Mortgage Loan was
not more than 95% of the Original Value of such Mortgage Loan; and

                 (xiv) With respect to each Buydown  Mortgage  Loan, the Buydown
Funds  deposited  in the Buydown  Account,  if any,  will be  sufficient,  after
crediting  interest  at the rate per annum,  if any,  specified  in the  buydown
agreement  compounded  monthly to the  Buydown  Account  and adding the  amounts
required to be paid by the Mortgagor,  to make the scheduled  payments stated in
the Mortgage Note for the term of the Buydown Subsidy Agreement.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.03 shall  survive  delivery of the  respective  Mortgage
Files to the Trustee.  Upon  discovery by CMSI or the Trustee of a breach of any
of the foregoing  representations  and warranties which materially and adversely
affects the  interests of the  Certificateholders  in the related  Mortgage Loan
(including  any Mortgage  Loan  substituted  for a  nonconforming  Mortgage Loan
pursuant to Section 2.04),  the party  discovering such breach shall give prompt
written  notice to the other  parties  hereto.  If within 60 days of the date of
such  notice of breach  or,  with the prior  written  consent  of a  Responsible
Officer of the Trustee,  such longer period specified in such consent, CMSI does
not cure such breach in all material respects  (including by substitution of one
or more Eligible  Substitute  Mortgage  Loans if and to the extent  permitted by
Section 2.04), CMSI shall repurchase such Mortgage Loan from the Trustee.

         Any such repurchase of a Mortgage Loan by CMSI shall be accomplished in
the  manner and at the  repurchase  price set forth in  Section  2.02.  Any such
repurchase  shall be  considered a prepayment  in full of such  Mortgage Loan on
such Due Date and shall be deposited  (net of all  Voluntary  Advances,  Trustee
Advances and Advance Amount  Advances with respect to such Mortgage Loan,  which
shall be reimbursed to the Trustee or deemed reimbursed to CMSI, as the case may
be) by CMSI in the  Certificate  Account  and,  upon  receipt by the  Trustee of
written  notification  of such deposit signed by an Authorized  Officer of CMSI,
the Trustee  shall  release to CMSI the related  Mortgage File and shall execute
and deliver such  instruments  of transfer or  assignment,  in each case without
recourse,  as CMSI shall reasonably  request,  to vest in CMSI any Mortgage Loan
released  pursuant  hereto.  Any repurchase by CMSI of a Mortgage Loan hereunder
shall be deemed to include the right to receive any Remittance  thereon  payable
after the month of repurchase,  and the Trustee shall,  upon receipt of any such
Remittance,  promptly  remit  the  amount  of such  Remittance  to  CMSI.  It is
understood  and agreed that the  obligation of CMSI to  repurchase  any Mortgage
Loan as to which a breach  occurred and is continuing and the limited  indemnity
set forth in the following  paragraph shall constitute the sole remedies against
CMSI respecting such breach available to the  Certificateholders  or the Trustee
on behalf of the Certificateholders.

         Section 2.04.  Substitution of Eligible  Substitute  Mortgage Loans for
Nonconforming Mortgage Loans.

         (a) CMSI shall  have the  right,  in an event  requiring  a  repurchase
pursuant to Section 2.02 or 2.03, to substitute one or more Eligible  Substitute
Mortgage  Loans  for any one or more  nonconforming  Mortgage  Loans,  any  such
substitution  to take  place on the day  designated  by CMSI (the  "Substitution
Day")  occurring  before a date two years  after  the  Startup  Day (or,  if the
Substitution  Day is not a Business  Day,  the next  proceeding  Business  Day),
subject to the  satisfaction  of the  conditions  set forth in Section  2.01 and
subject to the satisfaction of the following conditions;

                 (i) no Event of Default shall have occurred and be continuing;

                                       43
<PAGE>

                 (ii) the aggregate Adjusted Balance of all Eligible  Substitute
Mortgage Loans  substituted on the  Substitution Day (determined with respect to
each Eligible  Substitute  Mortgage Loan as of the  Substitution  Day) shall not
exceed an amount equal to 40% of the aggregate  Adjusted Balance of all Mortgage
Loans as of the Closing Date;

                 (iii) the Trustee shall have received an Officer's  Certificate
(A) stating that all conditions precedent to such substitution specified in this
subsection  (a) have been  satisfied and attaching as an exhibit a  supplemental
Mortgage Loan schedule (the "Supplemental Mortgage Loan Schedule") setting forth
the same type of  information  as  appears on the  Mortgage  Loan  Schedule  and
representing   as  to  the  accuracy   thereof  and  (B)  confirming   that  the
representations and warranties  contained in Section 2.03 (other than paragraphs
(i) and (xi) thereof) are true and correct in all material respects with respect
to the Eligible  Substitute  Mortgage Loans on and as of the  Substitution  Day,
provided that remedies for the inaccuracy of such  representation are limited as
set forth in Sections 2.02, 2.03 and this 2.04; and

                 (iv) the  Trustee  shall  have  received,  not  later  than the
Substitution  Day, an Opinion of Counsel  (who may not be an employee of CMSI or
of an  Affiliate  of CMSI) and, if required  by such  counsel,  a letter from an
accountant, dated the Substitution Day, to the effect (A) that all conditions to
such substitution specified in this subsection (a) have been satisfied, (B) that
the Eligible  Substitute  Mortgage Loans are "qualified  replacement  mortgages"
within the meaning of Code Section 860G(a)(4),  and (C) that the substitution of
such Eligible Substitute Mortgage Loans will not result in the  disqualification
of the Trust Fund as two separate  REMICs  under the Code or  otherwise  subject
either REMIC to any tax.

         (b)  In  the  event  that,  on  the   Substitution   Day,  any  Prepaid
Installments have been received in the Certificate  Account with respect to such
Mortgage Loan, the full amount of such Prepaid  Installment shall be paid on the
Substitution Day to CMSI from the Certificate Account.

         (c)  Concurrently  with the satisfaction of the conditions set forth in
Section 2.04(a) above and the grant of such Eligible  Substitute  Mortgage Loans
to the  Trustee  pursuant  to  Section  2.04(a)  above,  (A)  Exhibit  B to this
Agreement  shall be deemed to be amended to exclude  all  Mortgage  Loans  being
replaced by such Eligible Substitute Mortgage Loans and to include,  pursuant to
Section  10.01,  the  information  set forth on the  Supplemental  Mortgage Loan
Schedule  with  respect to such  Eligible  Substitute  Mortgage  Loans,  and all
references  in this  Agreement to Mortgage  Loans shall  include  such  Eligible
Substitute  Mortgage  Loans  and (B)  the  Trustee  shall  release  to CMSI  the
nonconforming Mortgage Loan or Loans and execute and deliver such instruments of
transfer or assignment as may be required to transfer, without recourse, to CMSI
such nonconforming Mortgage Loan or Loans.

         Section  2.05.   Authentication   of  Certificates.   The  Trustee  has
authenticated  and delivered or caused to be  authenticated  and delivered to or
upon the order of CMSI, in accordance  with the CMSI Order,  in exchange for the
Mortgage Loans,  concurrently with the transfer and assignment to the Trustee of
the Mortgage Loans, Certificates duly authenticated by the Trustee in authorized
denominations  evidencing  the entire  ownership of the Trust Fund.  The Trustee
acknowledges  issuance  to it of the Class L Regular  Interest  on behalf of the
Upper-Tier REMIC.

                 CERTIFICATE ACCOUNT; PAYMENTS AND STATEMENTS TO
               CERTIFICATEHOLDERS; ADMINISTRATION AND SERVICING OF
                                 MORTGAGE LOANS

         Section  3.01.  Collection  of Moneys.  Except as  otherwise  expressly
provided  herein,  the  Trustee  may demand or cause to be  demanded  payment or
delivery of, and shall receive and collect, directly and without intervention or
assistance  of any  fiscal  agent or other  intermediary,  all  money  and other
property payable to or receivable by the Trustee pursuant to this Agreement. The
Trustee  shall hold all money and  property  received by it as part of the Trust
Fund and shall apply it as provided in this Agreement.

         CMSI shall make  reasonable  efforts to collect all payments called for
under the terms and  provisions of the Mortgage  Loans and shall,  to the extent
such  procedures  shall be consistent  with this  Agreement,  follow such normal
collection  procedures as it deems  necessary and  advisable.  CMSI shall not be
required to institute litigation with respect to collection of any payment if it
reasonably  questions  its ability to enforce the provision of the Mortgage Loan
under which such payment is required. Consistent with the foregoing, CMSI may in
its discretion  (a) waive any late payment  charge or any  prepayment  charge or
penalty  interest in  connection  with the  prepayment of a Mortgage Loan or any
assumption  fees or other fees which may be collected in the ordinary  course of
servicing such Mortgage Loan and (b) arrange with a Mortgagor a schedule for the
payment of principal and interest due and unpaid after the  applicable Due Date,
provided,  if the  arrangement  is for a  period  of  more  than 90  days,  CMSI
reasonably believes that without such arrangement the Mortgagor would default on
the related  Mortgage  Loan.  Regardless of whether any  arrangement of the type
described  in  clause  (b)  above  is  made,  any such  Mortgage  Loan  shall be
considered delinquent for all purposes of this Pooling Agreement.

         Section  3.02.  Certificate  Account.  (a) On or before the Issue Date,
CMSI shall open or cause to be opened  with a  Depository,  Depositories  or the
Trustee  one  or  more  accounts  in  the  name  of  the  Trustee,  which  shall
collectively be the "Certificate  Account".  The Certificate  Account will be an
Investment  Account if so specified in Article XII;  otherwise,  the Certificate
Account with be a non-interest bearing account.  CMSI, on behalf of the Trustee,
shall  promptly  deposit,  or cause to be  deposited,  daily in the  Certificate
Account,  within one Business Day following receipt and posting, all Remittances
related to Affiliated  Mortgage Loans received by it. Remittances related to the
CitiMae  Mortgage Loans shall be deposited  into the Custodial  Accounts for P&I
and the Certificate  Account in accordance  with Section 3.03. All  Remittances,
any amount  required to be  deposited  in the  Certificate  Account  pursuant to
Section 2.01, all other deposits  therein  pursuant to this  Agreement,  and all
investments made with such moneys,  including all income or other gain from such
investments,  shall be held by the Trustee in the Certificate Account as part of
the Trust  Fund as herein  provided,  except  for  amounts  from  Buydown  Funds
required to be deposited  pursuant to Section  3.06,  which shall be held by the
Trustee  in the  Buydown  Account  on  behalf  of  the  Mortgagors,  subject  to
withdrawal  by the Trustee or CMSI as  servicer  for the  purposes  set forth in
subsections  (b)  and  (c)  of  Section  3.04.  All  funds  withdrawn  from  the
Certificate  Account  pursuant to subsection (b) of Section 3.04 for the purpose
of making distributions to the Certificateholders shall be applied in accordance
with said subsections.  The Trustee shall take such steps as CMSI may reasonably
request in order to enable  CMSI to make  deposits to and  withdrawals  from the
Certificate Account in accordance with Sections 3.03, 3.14 and 3.16.

         Funds in the  Certificate  Account shall be invested and  reinvested by
the Trustee at CMSI's  written  direction  (subject to  subsections  (d) of this
Section 3.02) in one or more Eligible  Investments  bearing  interest or sold at
discount. Notwithstanding the foregoing, no investment of any amount held in the
Certificate Account may mature later than the Business Day immediately preceding
the next  Distribution  Date;  provided,  however,  that investments  (including
repurchase  agreements) on which the Trustee, in its commercial capacity, is the

                                       45
<PAGE>

obligor,  may mature on a  Distribution  Date if, under this Section 3.02,  such
investment could otherwise mature on the Business Day immediately preceding such
Distribution Date.

         All  income  from  investment  of  moneys  deposited  in a  Certificate
Account,  and all  proceeds  of  disposition  of any  assets in the  Certificate
Account,  shall be deposited by the Trustee, the Servicer or the Master Servicer
in such Certificate  Account  immediately  upon receipt,  and any loss resulting
from such investment shall be charged to such Certificate  Account.  The Trustee
shall have no liability for any loss incurred in connection  with any investment
or any  sale or  liquidation  thereof  pursuant  hereto,  unless  caused  by its
negligence or willful misconduct.

         CMSI may deposit in each of the Certificate Account,  Servicing Account
and Buydown Account the appropriate  payments,  collections and funds in respect
of one or more series of  certificates  issued  under a  registration  statement
covering the CitiCertificates or similar certificates;  provided that the senior
class  of  certificates  of each  such  other  series  and the  senior  Class of
CitiCertificates  are rated "AAA" or its  equivalent  or in the category "AA" or
its equivalent and the  subordinated  class of  certificates  of each such other
series  and the  subordinated  Class of  CitiCertificates  are rated in the same
category by each Rating Agency, and provided further that separate accounting is
maintained.

         (b) Funds and other  property in the  Certificate  Account shall not be
commingled with any other moneys or property of the Trustee. Notwithstanding the
foregoing,  the Trustee may hold any funds or other property received or held by
it as part of the Certificate Account in collective accounts maintained by it in
the normal  course of its business and  containing  funds or property held by it
for other persons; provided that such accounts are under the sole control of the
Trustee and the Trustee maintains  adequate records  indicating the ownership of
all such  funds or  property  and the  portions  thereof  held for credit to the
Certificate Account.

         (c) CMSI will not direct  the  Trustee  to make any  investment  of any
funds  in  the  Certificate  Account  or to  sell  any  investment  held  in the
Investment Account except under the following terms and conditions:

                 (i) each such  investment  shall be made in the name of the 
Trustee (in its capacity as such) or in the name of a Qualified Nominee of the 
Trustee; and

                 (ii) each such investment  shall be a "cash flow investment" as
defined in Code Section 860G(a)(6).

         (d) Generally, no Eligible Investment shall be disposed of prior to Its
maturity; provided, however, if any amounts are needed for disbursement from the
Certificate Account and sufficient uninvested funds are not available therein to
make such  disbursement,  in the absence of a CMSI Order for the  liquidation of
investments held therein in an amount  sufficient to provide the required funds,
the Trustee  shall cause to be sold or otherwise  converted to cash a sufficient
amount  of  the  investments  in the  Certificate  Account;  provided,  further,
however,  that prior to any such sale or conversion  to cash,  the Trustee shall
have received (i) an Opinion of Counsel (which opinion may not be provided by an
employee of CMSI or of an  Affiliate  of CMSI) that such sale or  conversion  to
cash shall not constitute a "prohibited transaction" under Code Section 860F(a),
or (ii) (a) if such sale or  conversion to cash  constitutes  such a "prohibited
transaction",  the  consent of the  Holders of 100%  Percentage  Interest of the
Residual  Certificates  to the  prohibited  transaction  together with each such
Holder's  proportionate  share of any tax imposed on the Trust Fund attributable
to such  transaction  and (b) an Opinion of Counsel  (which  opinion  may not be
provided  by an  employee  of  CMSI  or of  an  Affiliate  of  CMSI)  that  such
transaction will not disqualify the Trust Fund as a REMIC.

                                       46
<PAGE>

         (e) The  Trustee  shall not in any way be held  liable by reason of any
insufficiency  in the  Certificate  Account or the  Buydown  Account  except for
losses on  investments  which are  liabilities  of the Trustee in its commercial
capacity.

         (f) Unless it shall have  otherwise  agreed in writing  with CMSI,  the
Trustee  shall not be  required  to enter into  repurchase  obligations  for the
investment of funds in the Investment  Account with any Person whose  repurchase
obligations would be Eligible  Investments only if the requirements of subclause
(B) of clause (iii) of the  definition of the term "Eligible  Investments"  were
complied with in connection with such investment.

         Section 3.03.  CitiMae Mortgage Loans;  Custodial  Accounts for P&I and
Certificate  Account  Deposits.  (a)  The  Master  Servicer  shall  cause  to be
established and maintained  segregated Custodial Accounts for P&I and segregated
Escrow  Accounts  in  accordance  with the  requirements  of the Guide and shall
deposit or cause to be deposited  therein  within two Business  Days the amounts
related to the CitiMae Mortgage Loans required by the Servicing Agreements to be
so deposited  except any Retained  Fixed Yield Amounts.  Proceeds  received with
respect to individual  CitiMae  Mortgage  Loans from any title,  hazard or other
insurance  policy  covering such  Mortgage Loan other than any Primary  Mortgage
Insurance  Certificate shall be deposited first in the applicable Escrow Account
if required for the  restoration  or repair of the related  Mortgaged  Property.
Proceeds from such insurance  policies not so deposited in the applicable Escrow
Account and proceeds from any Primary Mortgage  Insurance  Certificate  shall be
deposited in the Custodial  Account for P&I and shall be applied to the balances
of the related  CitiMae  Mortgage  Loans as payments of interest and  principal.
Conduit Servicers are authorized to make withdrawals from the Custodial Accounts
for P&I  for the  purposes  required  or  permitted  by  this  Agreement  and in
accordance  with  the  Guide.  The  Trustee  shall  have no  responsibility  for
monitoring such  withdrawals.  The Custodial  Accounts for P&I shall each bear a
designation clearly indicating that the funds deposited therein are held for the
benefit of the  Certificateholders.  Amounts  deposited in any Custodial Account
for P&I shall be fully insured by the FDIC. To the extent  amounts  received for
deposit in any Custodial Account for P&I will not be fully insured,  such excess
shall either,  at the option of the Master  Servicer,  be secured by one or more
Eligible Investments maturing not later than the Determination Date with respect
to such amounts or in every other case be promptly  remitted to the  Certificate
Account or the account  referred to in (d) below,  such Eligible  Investments as
evidenced by an Opinion of Counsel  delivered  and  acceptable to the Trustee to
the effect that the Master  Servicer has either a claim to the funds held by the
institution  or a perfected  first security  interest  against any such Eligible
Investments superior to the claims of any other depositor or general creditor of
such institution.

         The Master  Servicer  shall  advance the payment of property  taxes and
insurance  premiums and other similar payments  relating to the CitiMae Mortgage
Loans that are not timely  paid by the  Mortgagors  or  advanced  by the Conduit
Servicers  on the date when  such  tax,  premium  or other  cost for which  such
payment is  intended  is due,  but the Master  Servicer  shall be required to so
advance only to the extent that such advances, in the good faith judgment of the
Master  Servicer,  will be recoverable  by the Master  Servicer out of Insurance
Proceeds or Liquidation  Proceeds or otherwise from the related CitiMae Mortgage
Loans.

         Any amounts  received by a Conduit  Servicer  with respect to a CitiMae
Mortgage Loan shall be deemed to have been  received by the Master  Servicer for
purposes of this Agreement.  In the event a Conduit  Servicer fails to remit any
amounts received by the Conduit Servicer and required to be remitted  hereunder,
the Master  Servicer shall be obligated to transmit the required  amounts to the
Trustee regardless of the failure of the Conduit Servicer.

         The Master  Servicer shall keep, or cause to be kept, and maintain,  or
cause to be maintained,  separate accounting on a Mortgage Loan by Mortgage Loan
basis, for any remittances to or payments from the Custodial Accounts for P&I.

                                       47

         (b) Within three days (or the next succeeding Business Day if the third
day is not a Business Day) after the receipt by a Conduit  Servicer of Principal
Prepayments in full, Liquidation or Insurance Proceeds with respect to a CitiMae
Mortgage  Loan (not required to be applied to the  restoration  or repair of the
related  Mortgaged  Property)  or (ii) the  Substitution  Adjustment  Amount  in
connection  with  any  substitution  of a  mortgage  loan or  proceeds  from the
repurchase  of a Mortgage  Loan are  deposited  by the  Conduit  Servicer in the
Custodial  Account for P&I,  the Master  Servicer  shall  withdraw or direct the
withdrawal from the Custodial  Accounts for P&I of such amounts and deposit such
amounts in accordance with this paragraph (b);  provided,  that, so long as CMSI
or an Affiliate of CMSI is the Master Servicer,  CMSI or the Conduit Subservicer
may consent to the  withdrawal  from the Custodial  Accounts for PI in the month
following  the month of receipt by a Conduit  Servicer  of amounts  representing
Principal Prepayments in full, Liquidation Proceeds and Insurance Proceeds.

         Not later  than the  Determination  Date,  the  Master  Servicer  shall
withdraw or direct the withdrawal  from any funds in the Custodial  Accounts for
P&I and deposit into the Certificate Account the following amounts:

                 (i)  Scheduled  installments  of principal  and interest on the
             CitiMae   Mortgage  Loans  received  or  advanced  by  the  Conduit
             Servicers which were due the first day of the current month, net of
             Conduit Servicing Fees due Conduit Servicers and any Retained Fixed
             Yield Amounts, if any;

                 (ii)  Principal   Prepayments  in  full  and   Liquidation  and
             Insurance  Proceeds (a) received by Conduit  Servicers  for CitiMae
             Mortgage  Loans but not yet  withdrawn and remitted to the Servicer
             in the current month,  in those cases where Conduit  Servicers must
             remit such  payments  within  three days or (b) received by Conduit
             Servicers in the  immediately  preceding month in those cases where
             the Master  Servicer  has  consented  thereto,  net, in the case of
             Liquidation  Proceeds and Insurance Proceeds,  of Conduit Servicing
             Fees due Conduit Servicers;

                 (iii) Partial  prepayments of principal received by the Conduit
             Servicer  for  such  Mortgage  Loans in the  immediately  preceding
             calendar  month,  or the  current  month  in the  case  of  partial
             prepayments  received with the scheduled  installments of principal
             and interest  which were due on the first day of the current month;
             and

                  (iv) Payments for repurchase of CitiMae Mortgage Loans by 
             Conduit Servicers.

         (c) Except as otherwise  provided  herein,  the following  payments and
collections  received or made by the Master Servicer shall be deposited into the
Certificate  Account on the  Certificate  Account  Deposit  Date  (other than in
respect of principal of and interest on the Mortgage  Loans due on or before the
Cut-Off Date):

         Not later than the  Certificate  Account  Deposit  Date.  the foregoing
withdrawals  and any  amounts  remitted  to the  Conduit  Servicers  pursuant to
paragraph  (a) and (b) above shall be deposited  into the  Certificate  Account;
provided,  however, that (x) any Principal  Prepayments in full,  Liquidation or
Insurance  Proceeds  with  respect to the  CitiMae  Mortgage  Loans shall not be
required to be deposited in the Certificate Account earlier than the Certificate
Account Deposit Date in the month  succeeding the month in which such amount was
received by the related  Conduit  Servicer and (y) the  Substitution  Adjustment
Amount in connection with any Substitute Mortgage Loan and the proceeds from the
repurchase  of a CitiMae  Mortgage Loan shall not be required to be deposited in
the Certificate Account earlier than the Certificate Account Deposit Date in the
month following the month during which the circumstances which gave rise to such
substitution or repurchase occurred.

         In  addition,  the Master  Servicer  shall  deposit in the  Certificate
Account not later than the third Business Day preceding each Certificate Account
Deposit  Date, in the case of clause (i) and in the case of clauses (ii) through
(iv) below on the Certificate Account Deposit Date:

                                       48
<PAGE>

                 (i) Any  Voluntary  Advances  with  respect  to  the  CitiMae
             Mortgage  Loans  by  the Master Servicer in respect of such 
             Distribution Date;

                 (ii) The amount,  if any,  with  respect to a CitiMae  Mortgage
             Loan  which was  prepaid  in full by the  Mortgagor  or for which a
             final liquidation has occurred during the preceding  calendar month
             required to be deposited by the Master Servicer pursuant to Section
             3.25 hereof;

                 (iii) All Liquidation  Proceeds received in the preceding month
             by the  Master  Servicer  in  connection  with the  liquidation  of
             defaulted  CitiMae  Mortgage  Loans,  net  of  related  Liquidation
             Expenses;

                 (iv) All Insurance  Proceeds with respect to a CitiMae Mortgage
             Loan received in the preceding month by the Master Servicer,  other
             than proceeds  applied to the  restoration or repair of the related
             Mortgaged Property; and

                 (v) With respect to the CitiMae Mortgage Loans, any amount
             required to be deposited pursuant to Section 3.21.

         CMSI  shall  deposit  in the  Certificate  Account  not later  than the
Certificate   Account  Deposit  Date  the  Substitution   Adjustment  Amount  in
connection  with any Substitute  Mortgage Loan being  substituted and the amount
specified  in  Sections  2.02 and 2.03 paid by CMSI in  respect  of any  CitiMae
Mortgage  Loan  or  property  acquired  in  respect  thereof  as  to  which  the
circumstances  giving rise to substitution or purchase occurred during the month
preceding  such  Certificate  Account  Deposit  Date  (and  not  substituted  or
purchased  by a Conduit  Servicer  for which a deposit has already  been made to
such Conduit Servicer's  Custodial Account for P&I or otherwise deposited by the
Master Servicer).

         (d) Prior to the  Certificate  Account Deposit Date the Master Servicer
may deposit the amounts  described in Section  3.03(b) in a separate  account in
the  name of the  Master  Servicer  and  the  Trustee  (such  account  shall  be
maintained  in the trust  department of a Depositor and shall bear a designation
clearly indicating that the principal of all investments in such account is held
for the  benefit  of the  Trustee  on  behalf  of the  Certificateholders)  (the
"Investment  Account") for investment only in one or more Eligible  Investments.
The Master  Servicer shall bear any and all losses  incurred on any  investments
made with such funds and shall be entitled to retain all gains  realized on such
investments as additional  compensation for its services as Master Servicer. The
amount of any  losses  incurred  in  respect  of any such  investments  shall be
deposited in the Investment  Account by the Master Servicer out of its own funds
immediately as realized.  Any successor  master servicer  appointed  pursuant to
this  Agreement  shall  not  be  responsible  for  losses  attributable  to  its
predecessor.  No investments  held in the Investment  Account shall mature later
than the Certificate Account Deposit Date.

         Section 3.04. Distributions.  (a) By 11:00 a.m. (New York City time) on
each  Distribution  Date,  the Trustee  shall cause to be  distributed  from the
Certificate  Account (or, to the extent  provided in Sections  3.27 and 3.28 and
Articles XII and XIII, the  Upper-Tier  REMIC Account) or shall cause the Paying
Agent to  distribute  from a  designated  account to each  Certificateholder  of
record on the related  Record  Date  (other  than as  provided  in Section  9.01
respecting the final distribution) by check mailed to such  Certificateholder at
the address appearing in the Certificate Register; if eligible for wire transfer
as set forth in Article XII and if the Trustee has received wiring  instructions
from the  Certificateholder by wire transfer;  or by such other means of payment
as such  Certificateholder,  CMSI,  the Paying  Agent and the  Trustee (if it is
making  payments  directly to the  Certificateholders)  shall agree,  the amount
required  to  be   distributed  to  such   Certificateholder   pursuant  to  the
Certificates  and this  Agreement.  If wiring  instructions  are received by the
Trustee,  such  instructions  will  remain  in  effect  until  changed  by  such
Certificateholder by written notice to the Paying Agent and the Trustee at least
five Business Days prior to a subsequent Distribution Date.

                                       49
<PAGE>

         In the event CMSI  appoints a Paying  Agent,  the Trustee  will,  on or
prior to each Distribution Date,  deposit,  in immediately  available funds from
funds  available in the  Certificate  Account,  in an account  designated by the
Paying Agent the amount required to be distributed to the  Certificateholders on
such  Distribution Date pursuant to subsections (b) and (c) of this Section 3.04
and,  unless such Paying Agent is CMSI, the Trustee will promptly notify CMSI of
its  deposit  or its  failure to make such  deposit.  CMSI will cause any Paying
Agent  which is not the  Trustee  to  execute  and  deliver  to the  Trustee  an
instrument  in which such Paving  Agent agrees with the Trustee that such Paying
Agent will:

         (1) hold all  amounts  deposited  with it by CMS I or the  Trustee  for
payment on the  Certificates in trust for the benefit of the  Certificateholders
until such amounts are paid to such  Certificateholders or otherwise disposed of
as herein provided;

         (2) give the Trustee notice of any default by CMSI the making of any
such deposit; and

         (3) at any time during the continuance of any default of CMSI in making
such a deposit,  upon the written  request of the Trustee,  forthwith pay to the
Trustee all amounts so held in trust by such Paying Agent.

         For each  distribution  to the  Certificateholders  or deposit with the
Paying  Agent,  the Servicer  will use  Affiliated  Uncommitted  Cash to make an
Affiliated  Certificate Account Advance and the Master Servicer will use Conduit
Uncommitted  Cash to make a Conduit  Certificate  Account  Advance  to cover any
Remittance  Delinquencies  relating to the Affiliated  Mortgage Loans or CitiMae
Mortgage  Loans,  respectively,  prior  to  making  any  Voluntary  Advances  or
requesting that the Trustee (in its individual  capacity) make a Conduit Trustee
Advance or Affiliated Trustee Advance (or an Advance Account Advance).

         (b) Based on payments  received with respect to the Mortgage  Loans, on
each Determination Date the Servicer shall determine:

                 (i) the Pool Distribution Amount;

                 (ii) the  Class A  Interest  Amount,  the Class  A-IO  Interest
Amount,  the Class A Unpaid Interest  Shortfall,  the Class A-IO Unpaid Interest
Shortfall,  the Class M Interest Amount, the Class M Unpaid Interest  Shortfall,
the Class B Subclass  Interest  Amount  for each Class B Subclass  and the Class
B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Unpaid Interest Shortfall for
each Class B Subclass;

                 (iii) the Class A Optimal Principal Amount,  the Group I Non-PO
Principal Amount, the Group II Non-PO Principal Amount, the Class A PO Principal
Amount,  Class M Optimal  Principal  Amount and the Class B-1,  Class B-2, Class
B-3, Class B-4 and Class B-5 Optimal Principal Amounts;

                 (iv) the Class A  Principal  Distribution  Amount,  the Class M
Principal Distribution Amount and the Class B-1, Class B-2, Class B-3, Class B-4
and Class B-5 Principal Distribution Amount;

                 (v)     the PO Loss Amount;

                 (vi)    the Available PO Loss Funds; and

                 (vii) Such other  information  as may be required to  determine
the  distributions to be made to  Certificateholders  in accordance with Article
XII.

         On each Distribution  Date, the Trustee shall distribute or cause to be
distributed from funds on deposit in the Certificate  Account (or, to the extent
provided in Sections  3.27 and 3.28 and  Articles XII and XIII,  the  

                                       50
<PAGE>

Upper-Tier REMIC Account) to each  Certificateholder  of record on the preceding
Record  Date  such   Certificateholder's   share  (based  on  the   denomination
represented by Certificates of the applicable  Class held by such Holder) of the
amounts  distributable  to  such  Class  or  Subclass  in  accordance  with  the
priorities set forth in Articles XII and XIII, each such amount being the amount
thereof set forth in the applicable Distribution Date Statement. Any such amount
withdrawn for application to amounts  distributable in respect of interest or in
reduction of Stated Amount  pursuant to subsection (d) of this Section 3.04, but
not distributed because of the non-presentation of the related Certificates,  or
because the check for such payment is returned  undelivered,  shall be set aside
and held by the  Trustee  in a separate  trust  account  for the  benefit of the
Holders of such  Certificates,  and all such amounts will be deemed to have been
distributed to such Holders for the purpose of any calculations required by this
Agreement and will no longer be available for  application  to any other amounts
due under this Agreement;  provided,  that after two years, any such amount that
remains in such separate account shall be returned to the Certificate Account or
the Upper-Tier  REMIC Account,  as the case may be, or, upon  termination of the
Trust Fund pursuant to Article IX, to the Holder of the Class LR Certificates or
the Class R Certificates,  as appropriate,  as of the Termination Date and after
such payment the Holders of such Certificates shall be required to seek payments
as unsecured general creditors from the Certificate Account or the Holder of the
Class LR or Class R Certificates, as the case may be.

         (c) On each Distribution  Date, so long as CMSI shall have prepared and
delivered  to the  Trustee a  Distribution  Date  Statement  in  respect of such
Distribution Date and the Trustee (based on such statement) shall have made, or,
in accordance  with this Section 3.03, set aside from amounts in the Certificate
Account an amount  sufficient to make the distributions on the Certificates then
required to be made as indicated in such  Distribution  Date Statement,  plus an
amount  equal to the  Affiliated  Uncommitted  Cash and the Conduit  Uncommitted
Cash, if any, to be in the Certificate  Account as of such Distribution Date (to
the extent not required for either a Conduit  Certificate  Account Advance or an
Affiliated  Certificate  Account  Advance),  the amount of which unremitted cash
shall have been certified to the Trustee by CMSI, the cash balance, if any, then
remaining  in the  related  Certificate  Account  shall be  withdrawn  from such
Certificate Account by or on behalf of the Trustee and applied to the payment of
the CMSI Fee,  if any (to the extent not  already  retained  by the  Servicer or
Master Servicer  pursuant to Section 3.23), the amount of such payment being set
forth in a certificate of a Servicing Officer or a Responsible  Officer,  as the
case may be. The balance,  if any, of the amount so  withdrawn  shall be paid on
such Distribution Date by or on behalf of the Trustee to the Holder of the Class
LR Certificate.  The Trustee is hereby authorized by CMSI to authorize,  and the
Trustee hereby authorizes, the Depository to withdraw the amount of such balance
from  the  Certificate  Account  and  pay  it to the  Holder  of  the  Class  LR
Certificate, on its behalf in accordance with such Servicer's Certificate.

         (d) All  reductions in Stated  Amount of a Certificate  (or one or more
Predecessor  Certificates)  effected by  distributions  made on any Distribution
Date or reductions  thereof  without  distributions  pursuant to Article XIII or
otherwise in accordance  with this Pooling  Agreement  shall be binding upon all
Holders of such Certificate and of any Certificate  issued upon the registration
of transfer thereof or in exchange  therefor or in lieu thereof,  whether or not
such distribution is noted on such Certificate.  The final  distribution on each
Certificate  (including the final  distribution on any  Certificate  receiving a
distribution in connection with a termination pursuant to Section 9.01) shall be
payable  only  upon   presentation  and  surrender   thereof  on  or  after  the
Distribution Date therefor at the office or agency of the Trustee  maintained by
the Trustee for such purpose pursuant to Article XII.

         Whenever,  on the basis of distributions on the Mortgage Loans received
and expected to be received since the preceding Determination Date, CMSI expects
that the Stated Amount of any Class of CitiCertificates  will be reduced to zero
on the next  Distribution  Date it shall, not later than the third day preceding
such Distribution  Date, mail or cause to be mailed to the Trustee and each such
Person in whose name a  CitiCertificate  to be so retired is  registered  at the
close of business on the applicable Record Date a notice to the effect that:

                                       51
<PAGE>

                 (i) CMSI  expects that funds  sufficient  to reduce such Stated
Amount to zero will be available in the Certificate Account on such Distribution
Date, and

                 (ii) if such funds are available,  (A) such final  distribution
will be made on such Distribution Date, but only upon presentation and surrender
of such  CitiCertificate  at the office or agency of the Trustee  maintained for
such purpose pursuant to Article XII (the address of which shall be set forth in
such notice), and (B) no interest shall accrue on such CitiCertificate after the
end of the related  Interest  Accrual  Period with respect to such  Distribution
Date.

         (e)  Subject  to  the  foregoing  provisions  of  this  Section,   each
Certificate  delivered under this Agreement upon  registration of transfer of or
in exchange  for or in lieu of any other  Certificate  shall carry the rights to
unpaid  distributions  that were carried by such other  Certificate.  Any checks
mailed pursuant to subsection (a) of this Section 3.04 and returned  undelivered
shall be held in accordance with Section 3.04(b).

         (f)  Not  later  than  the  third  Business  Day  next  preceding  each
Distribution  Date,  the  Servicer  shall  prepare  or  cause to be  prepared  a
statement (a "Distribution  Date  Statement") with respect to such  Distribution
Date setting forth:

                 (i)  the  Distribution   Amount  for  such   Distribution  Date
(including the portion thereof which represents any Reimbursable  Class A Non-PO
Losses,  Reimbursable  Class  A PO  Losses,  Reimbursable  Class  M  Losses  and
Reimbursable Class B Losses for such Distribution Date);

                 (ii) the  aggregate  amount  of  interest  accrued  during  the
related  Interest  Accrual  Period  on  all  Outstanding   CitiCertificates  and
Certificates and any Non-Supported Interest Shortfalls;

                 (iii) the  aggregate  amount of interest to be  distributed  on
each Class of CitiCertificates then Outstanding, identifying the portion thereof
attributable to Class A Unpaid Interest  Shortfalls,  Class A-IO Unpaid Interest
Shortfall,  Class M  Unpaid  Interest  Shortfalls  or  Class B  Unpaid  Interest
Shortfalls;

                 (iv) the aggregate distribution in reduction of Stated Amount
to be made in respect of each Class of CitiCertificates then Outstanding;

                 (v) the amount in reduction of Stated Amount of the

Advance with respect to the  Affiliated  Mortgage  Loans or the Master  Servicer

preceding the Distribution  Date an amount equal to such Voluntary Advance or in
the  case of a  CitiMae  Mortgage  Loan an  amount  equal  to  such  advance  in
accordance  with Section 3.03. It is understood  and agreed that the election of
the  Servicer or the Master  Servicer to make any such  advance as  permitted by
this  subsection  (g) of Section 3.04 is based upon its good faith judgment that
the amount of such advance will be recoverable from future payments and proceeds
on the related Mortgage Loan, and that no obligation, express or implied, exists
respecting any such advance.

forth the information in paragraphs (i) through (viii).

         CMSI will provide Certificateholders that are federally insured savings
and  loan  associations  with  certain  reports,  and  will  provide  access  to
information and documentation regarding the Mortgage Loans included in the Trust
Fund,   sufficient  to  permit  such  associations  to  comply  with  applicable
regulations of the Office of Thrift Supervision.

         In addition to the  foregoing,  CMSI,  on behalf of the Trustee,  shall
file with the Internal  Revenue Service and furnish to  Certificateholders  such
statements or information at such times and in such manner as may
be required by the Code.

         Section 3.06. Application of Buydown Funds. On or before the Issue Date
if there are any Buydown  Mortgage  Loans in the Trust Fund,  CMSI shall open or
cause to be opened the Buydown  Account with the  Depository  in the name of the
Trustee,  on behalf of the  Mortgagors.  With respect to each  Buydown  Mortgage
Loan, on the Business Day next  following  receipt of the  Mortgagor's  required
monthly payment under the buydown agreement, CMSI will withdraw from the Buydown
Account and deposit, or cause to be deposited. in immediately available funds in
the Certificate Account an amount which, when added to such Mortgagor's payment,
will equal the full monthly  payment due under the Mortgage  Note. No later than
the fifth  Business Day preceding the last Business Day of each calendar  month,
CMSI  will  deposit,  or  cause  to be  deposited,  in the  Buydown  Account  in
immediately  available  funds an amount  equal to interest at the rate per annum
specified in the buydown agreement  compounded monthly on the Buydown Funds with
respect to each Buydown Mortgage Loan.

                                       54
<PAGE>

         If a Buydown  Mortgage is fully  prepaid  while Buydown Funds remain in
the Buydown Account,  the unpaid principal balance of such Buydown Mortgage Loan
will be reduced by the  amount of such  Buydown  Funds  (which  reduction  shall
constitute a Principal  Prepayment)  and, on the Business Day next following the
date of such Principal Prepayment, CMSI shall deposit, or cause to be deposited,
in the  Certificate  Account,  such Buydown  Funds.  If the property  securing a
Buydown  Mortgage  Loan is sold in  liquidation  of the  Buydown  Mortgage  Loan
(either by CMSI or the insurer  under any  related  Primary  Mortgage  Insurance
Certificate)  while  Buydown Funds remain in the Buydown  Account,  such Buydown
Funds shall be (i) deposited in the Certificate Account on the Business Day next
following  such  liquidation as a reduction of the unpaid  principal  balance of
such  Buydown  Mortgage  Loan or (ii) if and to the  extent  required  under any
applicable  Primary Mortgage Insurance  Certificate,  paid to the insurer of the
Mortgage Loan.

         Section 3.07. Tax Returns and Reports to Certificateholders.

         (a) For federal income tax purposes,  each of the Upper-Tier  REMIC and
the Lower-Tier  REMIC shall have a calendar year taxable year and shall maintain
its books on the accrual method of accounting.

         (b) The  Servicer  shall  prepare and file or cause to be prepared  and
filed  with the  Internal  Revenue  Service  and  applicable  state or local tax
authorities income tax or information returns for each taxable year with respect
to the Upper-Tier  REMIC and the Lower-Tier  REMIC,  containing such information
and at the times and in the  manner as may be  required  by the Code or state or
local  tax  laws,  regulations,  or  rules,  and  shall  furnish  or cause to be
furnished to  Certificateholders,  the  schedules,  statements or information at
such times and in such manner as may be required thereby.  Within 30 days of the
Startup Day, the Servicer shall furnish or cause to be furnished to the Internal
Revenue  Service,  on Form 8811 or as may otherwise be required by the Code, the
name, title, address, and telephone number of the person that the Holders of the
CitiCertificates may contact for tax information relating thereto, together with
such  additional  information  as may be required by such Form, and shall update
such  information  at the time or times and in the manner  required by the Code.
Such federal,  state or local income tax or information  returns shall be signed
by the Trustee or such other  person as may be required to sign such  returns by
the Code or state or local tax laws, regulations or rules.

         (c) In the first  federal  income tax return of each of the  Upper-Tier
REMIC and the Lower-Tier  REMIC for its short taxable year ending December 31 in
the year in which the Startup Day occurs, REMIC status shall be elected for such
taxable year and all succeeding taxable years.

         (d) The Servicer  will  maintain  such records  relating to each of the
Upper-Tier  REMIC and the  Lower-Tier  REMIC,  including  but not limited to the
income, expenses,  assets and liabilities thereof, and the adjusted basis of the
property thereof determined at such intervals as may be required by the Code, as
may be necessary to prepare the  foregoing  returns,  schedules,  statements  or
information.

         (e) Each  Holder  of a  Residual  Certificate  shall be  deemed to have
agreed, by acceptance  thereof,  to be bound by this Section 3.07 and by Section
5.02 and by the "REMIC-Related Covenants" set forth in Article XII.

         Section 3.08. Intentionally Deleted.

         Section  3.09.  Reports by  Independent  Accountants.  (a) CMSI  hereby
appoints KPMG Peat Marwick LLP as its  Independent  Accountants  for purposes of
preparing and  delivering the reports or  certificates  required by this Section
3.09. Upon any resignation by such firm, CMSI shall promptly appoint a successor
thereto  that  shall also be a firm of  Independent  Accountants  of  recognized
national  reputation.  If CMSI shall fall to  appoint a  successor  to a firm of
Independent   Accountants   which  has  resigned   within  15  days  after  such
resignation,  CMSI shall promptly notify the Trustee of such failure in writing.
If CMSI shall not have  appointed a  successor  within

                                       55
<PAGE>

10 days  thereafter,  the Trustee  shall  promptly  appoint a successor  firm of
Independent  Accountants  of recognized  national  reputation.  The fees of such
Independent  Accountants  and any such  successor  shall be  payable  by CMSI as
Servicer, or any successor Servicer.

         (b) On or before March 31 in relation to the Affiliated  Mortgage Loans
and September 30 in relation to the CitiMae Mortgage Loans of each year (each, a
"Report  Date"),  beginning with the March 31 and September 30,  respectively in
the year which  begins not less than three  months after the date of the initial
issuance of the  Certificates,  CMSI,  at its  expense,  shall cause the firm of
Independent  Accountants  appointed  pursuant to Section  3.09(a)  (who may also
render other  services to CMSI) to furnish a report to the Trustee to the effect
that such firm has  examined  certain  documents  and  records  relating  to the
servicing of mortgage loans under pooling and servicing agreements substantially
similar to this  Pooling  Agreement  (which  agreements  shall be described in a
schedule to such statement), and that such examination, which has been conducted
substantially  in compliance  with the audit guide for audits of  non-supervised
mortgagees  approved by the  Department  of Housing and Urban  Development,  the
Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for
Mortgage  serviced by FHLMC for use by independent  public  accountants  (to the
extent that the  procedures in such audit guide are  applicable to the servicing
obligations  set  forth  in  such   agreements),   has  disclosed  no  items  of
noncompliance  with the  provisions  of this  Pooling  Agreement  which,  in the
opinion of such firm, are material,  except for such items of  noncompliance  as
shall be set forth in such report.  For  purposes of such report,  such firm may
conclusively  presume that any pooling and  servicing  agreement  which  governs
certificates  offered  under a  common  registration  statement  under  the Act,
covering the  CitiCertificates or similar certificates with the CitiCertificates
is substantially similar to the Pooling Agreement, unless such other pooling and
servicing agreement expressly states otherwise.

         Section  3.10.  CMSI to Act as Servicer of Affiliated  Mortgage  Loans.
CMSI (or any  subservicer to whom such duties are delegated  pursuant to Section
6.06 hereof) shall service and  administer  the  Affiliated  Mortgage  Loans and
shall have the power and  authority,  acting alone,  to do any and all things in
connection with such servicing and administration which it may deem necessary or
desirable.   The  Servicer  shall  service  the  Affiliated  Mortgage  Loans  in
accordance with its normal  servicing  procedures for mortgage loans held in its
own  portfolio.  CMSI may perform its servicing  responsibilities  in connection
with the Affiliated Mortgage Loans through agents or independent  contractors as
set forth in Section 6.06.  Without  limiting the  generality of the  foregoing,
CMSI shall continue,  and is hereby authorized and empowered by the Trustee,  to
execute and deliver, on behalf of itself, the Certificateholders and the Trustee
or any of them, any and all instruments of satisfaction or  cancellation,  or of
partial or full release or discharge and all other comparable instruments,  with
respect to the  Affiliated  Mortgage  Loans and with  respect to the  properties
subject to their respective  Mortgages.  The Trustee shall furnish CMSI with any
powers of attorney and other  documents  necessary or appropriate to enable CMSI
to carry out its servicing and administrative duties hereunder.

         All costs incurred by CMSI in effecting the timely payment of taxes and
assessments on the properties  related to the Affiliated  Mortgage Loans subject
to the Mortgages shall not, for the purpose of calculating monthly distributions
to the  Certificateholders,  be added to the  amount  owing  under  the  related
Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit,
and such costs shall be recoverable by CMSI pursuant to Sections 3.16.

         The  relationship  of CMSI (and of any successor to CMSI as servicer or
Master Servicer under this Pooling  Agreement) to the Trustee under this Pooling
Agreement is intended by the parties to be that of an independent contractor and
not that of a joint venturer, partner or agent.

         Section 3.11. CMSI to Act as Master Servicer of CitiMae Mortgage Loans.
CMSI, as Master  Servicer,  shall service and  administer  the CitiMae  Mortgage
Loans and shall have full  power and  authority,  acting  alone  and/or  through
Conduit  Servicers,  to do any and all things in connection  with such servicing
and  administration

                                       56
<PAGE>

which it may de necessary or desirable in connection therewith. Without limiting
the generality of the foregoing,  the Master  Servicer in its own name is hereby
authorized  and empowered by the Trustee,  to execute and deliver,  on behalf of
the  Certificateholders  and the Trustee or any of them, any and all instruments
of satisfaction or cancellation,  or of partial or full release or discharge and
all other comparable instruments, with respect to the CitiMae Mortgage Loans and
other  comparable  instruments,  with respect to the CitiMae  Mortgage Loans and
with  respect to the  properties  subject to the  Mortgages.  The Trustee  shall
furnish  the Master  Servicer  with any powers of attorney  and other  documents
reasonably  necessary or appropriate to enable the Master  Servicer to carry out
its servicing and administrative duties of the CitiMae Mortgage Loans.

         Unless otherwise specified herein with respect to specific  obligations
of the Master  Servicer,  the Master  Servicer  shall service and administer the
CitiMae  Mortgage  Loans in the best  interests  of, and for the benefit of, the
Certificateholders, in accordance with prudent mortgage loan servicing standards
and procedures  accepted in the mortgage banking industry and in accordance with
the Guide.  The Master  Servicer shall promptly notify the Trustee in writing of
any event,  circumstance or occurrence which may adversely affect the ability of
the Master Servicer to service any CitiMae Mortgage Loan or to otherwise perform
and carry our its duties,  responsibilities and obligations under and accordance
with this Agreement.  The Master  Servicer shall at all times maintain  accurate
records  and books of  account  and an  adequate  system  of audit and  internal
controls.  All accounting and loan servicing records  pertaining to each CitiMae
Mortgage Loan shall be maintained in such manner as will permit the Trustee,  or
its duly authorized  representatives and designees to examine and audit and make
legible  reproductions  of records during  reasonable  business hours.  All such
records shall be maintained for the period  required by the Guide or such longer
period as is required by law.

         The Master Servicer intends to perform its servicing and administration
functions,  as Master Servicer,  pursuant to this Agreement  through the Conduit
Subservicer.  All  actions  by  the  Conduit  Subservicer  with  respect  to the
servicing and  administration  of the CitiMae Mortgage Loans shall be treated as
though  done by the  Master  Servicer  itself.  All  documents,  instruments  or
contracts  executed by the Conduit  Subservicer on behalf of the Master Servicer
shall be  treated  by the  Trustee as though  executed  by the  Master  Servicer
itself.

         All costs incurred by the Master Servicer or by any Conduit Servicer in
effecting the timely payment of taxes and assessments on the properties  subject
to the CitiMae Mortgage Loans shall not, for the purpose of calculating  monthly
distributions  to  Certificateholders,  be added to the amount  owing  under the
related CitiMae Mortgage Loans,  notwithstanding  that the terms of such CitiMae
Mortgage  Loan so permit,  and such  costs  shall be  recoverable  by the Master
Servicer to the extent permitted by Section 3.16.

         Section 3.12.  Servicing Agreements between Master Servicer and Conduit
Servicers;  Enforcement of Conduit Servicers.  (a) The Master Servicer may enter
into Conduit  Servicing  Agreements with Conduit Servicers for the servicing and
administration  of certain of the CitiMae  Mortgage  Loans.  References  in this
Agreement  to actions  taken or to be taken by the Master  Servicer in servicing
the CitiMae  Mortgage  Loans  include  actions taken or to be taken by a Conduit
Servicer on behalf of the Master Servicer. Each Servicing Agreement will be upon
such terms and conditions as are not inconsistent with this Agreement and as the
Master  Servicer and the Conduit  Servicer have agreed and shall be effective as
of the date of conveyance of the CitiMae  Mortgage Loans by CMSI to the Trustee.
With the approval of the Master  Servicer,  a Conduit  Servicer may delegate its
servicing obligations to third-party servicers,  but such Conduit Servicers will
remain obligated under the related Servicing Agreement.  The Master Servicer and
any Conduit Servicer may enter into amendments thereto; provided,  however, that
any such  amendments  shall be consistent with and not violate the provisions of
this Agreement.

         (b) As part of its servicing activities hereunder, the Master Servicer,
for the  benefit of the Trustee and the  Certificateholders,  shall  enforce the
obligations  of each  Conduit  Servicer  under the related  Servicing  Agreement
including,  without  limitation,  the  obligation to make advances in respect of
delinquent payments as required by a Servicing Agreement, to purchase a Mortgage
Loan on account of defective documentation,  as

                                       57
<PAGE>

described  in Section  2.02,  or on account of a breach of a  representation  or
warranty,  as described in Section 2.03. Such  enforcement,  including,  without
limitation, the legal prosecution of claims, termination of Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its good faith
business  judgment,  would  require  were it the owner of the  related  Mortgage
Loans.  The Master  Servicer shall pay the costs of such  enforcement at its own
expense,  but shall be  reimbursed  therefor  only (i) from a  general  recovery
resulting from such enforcement  only to the extent.  if any, that such recovery
exceeds all amounts due in respect of the related  Mortgage Loans or (ii) from a
specific recovery of costs, expenses or attorneys fees against the party against
whom such enforcement is directed.

         Section 3.13.  Liability of the Master  Servicer.  Notwithstanding  any
Servicing  Agreement,  any of the  provisions  of  this  Agreement  relating  to
agreements or arrangements  between the Master Servicer or a Conduit Servicer or
reference to actions taken through a Conduit  Servicer or otherwise,  the Master
Servicer shall remain obligated and liable to the Trustee and Certificateholders
for the servicing and  administering of the CitiMae Mortgage Loans in accordance
with the  provisions of Section 3.11 without  diminution  of such  obligation or
liability by virtue of indemnification from the Conduit Servicer and to the same
extent and under the same  terms and  conditions  as though the Master  Servicer
alone were servicing and  administering the CitiMae Mortgage Loans. For purposes
of making distributions to Certificateholders  all amounts received by a Conduit
Servicer in connection  with the CitiMae  Mortgage Loans shall be deemed to have
been received by the Master  Servicer,  and with respect to any successor Master
Servicer  from the time  such  successor  Master  Servicer  becomes  the  Master
Servicer,  whether  or not such  amounts  are  actually  remitted  by the Master
Servicer to the Master Servicer.  The Master Servicer shall be entitled to enter
into any  agreement  with a  Conduit  Servicer  and  nothing  contained  in this
Agreement shall be deemed to limit or modify such indemnification.

         Section 3.14. Collection of Certain Mortgage Loan Payments with respect
to an Affiliated Mortgage Loan;  Certificate Account. The Servicer shall deposit
or cause to be  deposited in the  Certificate  Account for  Affiliated  Mortgage
Loans the following amounts:

         (i) All payments  (other than  payments due and payable,  and Principal
Prepayments  received,  on or before the Cut-Off  Date) on account of principal,
including Principal Prepayments, on the Affiliated Mortgage Loans;

         (ii) All  payments  (other  than those due and payable on or before the
Cut-Off Date) on account of interest on the Affiliated  Mortgage  Loans,  net of
any Servicing Fee retained by it pursuant to Section 3.23;

         (iii) Any Buydown Funds required to be deposited pursuant to Section
3.06;

         (iv) All Liquidation Proceeds with respect to Affiliated Mortgage Loans
other than proceeds to be applied to the  restoration  or repair of the property
subject  to the  related  Mortgage  or  released  to the  related  Mortgagor  in
accordance with normal servicing procedures;

         (v) All proceeds of any Affiliated  Mortgage Loans or property acquired
in respect  thereof  repurchased  pursuant to Sections 2.02,  2.03, 2.04 or 9.01
(including any reserve funds established pursuant to Section 2.02);

         (vi) Any Voluntary Advance with respect to an Affiliated  Mortgage Loan
or Affiliated Trustee Advance;

         (vii)  Any  Advance  Account  Advance  with  respect  to an  Affiliated
Mortgage Loan; and

                                       58
<PAGE>

         (viii) The amount the Servicer is required to pay into the  Certificate
Account pursuant to Section 3.25 with respect to an Affiliated Mortgage Loan.

CMSI shall cause all amounts  collected with respect to the Affiliated  Mortgage
Loans  to be  deposited  in  immediately  available  funds on the  Business  Day
following  CMSI's  receipt of cash or a check or other  instrument  representing
payment of any such  amount.  In the event that CMSI must repay any such amount,
by reason of the  reversal of a  provisional  credit  owing to the dishonor of a
Mortgagor's check or otherwise, CMSI shall promptly (x) withhold (or cause to be
withheld) a corresponding  amount from a subsequent deposit into the Certificate
Account,  and (y) restate (or cause to be restated) its accounts  appropriately.
The  foregoing  requirements  for deposit in the  Certificate  Account  shall be
exclusive  (except  with  respect to payments of  Voluntary  Advances  made with
respect to  Affiliated  Mortgages  pursuant  to Section  3.04(g) and any Advance
Account Advance  pursuant to Section 8.14), it being understood and agreed that,
without  limiting  the  generality  of the  foregoing,  amounts  required  to be
deposited  into the  Servicing  Account,  amounts  in the  nature of  prepayment
charges,  late payment  charges,  assumption fees and other fees and proceeds of
reimbursements  of  Property   Protection  Expenses  received  with  respect  to
Affiliated  Mortgage  Loans  need not be  deposited  by CMSI in the  Certificate
Account.

         Section  3.15.  Collection  of  Taxes,  Assessments  and  Other  Items,
Servicing  Account.  In addition to the Certificate  Account,  Escrow  Accounts,
Custodial  Accounts for P&I and the Buydown  Account,  CMSI shall  establish and
maintain or cause to be established and maintained with  Depositories  Servicing
Accounts  and shall  deposit  therein  all  collections  of taxes,  assessments,
primary  mortgage  or hazard  insurance  premiums  or  comparable  items for the
account of the Mortgagors.  Withdrawals  from the Servicing  Account may be made
only to  effect  payment  of  taxes,  assessments,  primary  mortgage  or hazard
insurance  premiums  or  comparable  items,  to  reimburse  CMSI out of  related
collections  for any payments made pursuant to Section 3.10 regarding  taxes and
assessments,  Section  3.17  regarding  premiums on Primary  Mortgage  Insurance
Certificates  and Section 3.18 regarding  premiums on standard hazard  insurance
policies,  to refund to any Mortgagors any sums determined to be overages, or to
pay interest owed to Mortgagors on such account to the extent required by law or
to clear and terminate  such accounts at the  termination  of this  Agreement in
accordance with Section 9.01.

         Section 3.16. Permitted  Withdrawals from the Certificate Account. CMSI

Insurance  Proceeds and Liquidation  Proceeds) that represent late recoveries of
payments of  principal  and/or  interest  respecting  which any such advance was
made;

Retained Fixed Yield and not from assets of the Trust;

         (v) To reimburse  itself for advances made with respect to any Mortgage
Loan as  contemplated  by  Section  3.10 in  payment  of taxes  or  assessments,

Certificateholders  (including,  for  this  purpose,  Liquidation  Proceeds  and
Insurance Proceeds covering the property subject to the related Mortgage);

         (viii) To make  payments in the  amounts and in the manner  provided in
Sections 3.04, 12.01 and 13.01;

         (ix) To clear and terminate the Certificate Account pursuant to Section
9.01; and

         (x) To pay to itself or the Seller, as the case may be, with respect to
each  Mortgage  Loan or  property  acquired  in  respect  thereof  that has been

following such purchase and not  distributed as of the date on which the related
Adjusted Balance or Purchase Price is determined.

         CMSI  shall  keep and  maintain  (or  cause to be kept and  maintained)
separate accounting records, on a Mortgage  Loan-by-Mortgage Loan basis, for the
purpose of accounting for withdrawals  from the Certificate  Account pursuant to
clauses  (ii),  (iii),  (iv),(vi),  (vii),  (viii)  and  (xi) of  this  Section;
provided,  however.  that it is understood and agreed that such records need not
be retained by CMSI for a period longer than its five most recent fiscal years.

         Section 3.17.  Maintenance of Primary Mortgage Insurance  Certificates.
CMSI covenants and agrees to exercise its best reasonable efforts to cause to be
maintained  and kept in full force and effect each  Primary  Mortgage  Insurance
Certificate  in  accordance  with the terms of such Primary  Mortgage  Insurance
Certificate.  CMSI  agrees to effect the timely  payment of the  premium on each
Primary Mortgage Insurance Certificate, and such costs not otherwise recoverable
shall be  recoverable  by CMSI pursuant to Section 3.16. In connection  with its
activities as administrator  and servicer of the Mortgage Loans,  CMSI agrees to
present, on behalf of itself, the Trustee and the Certificateholders,  claims to
the insurer  under each  Primary  Mortgage  Insurance  Certificate  and, in this
regard,  to take such reasonable action as shall be necessary to permit recovery
under any Primary Mortgage Insurance Certificate respecting a defaulted Mortgage
Loan.  Pursuant to Section 3.16, any amounts collected by CMSI under any Primary
Mortgage  Insurance  Certificate shall be deposited in the Certificate  Account,
subject to  withdrawal  pursuant to Section  3.16.  CMSI shall have the power to
substitute for any Primary Mortgage Insurance  Certificate another substantially
equivalent policy issued by another insurer,  provided that

                                       60
<PAGE>

no such  substitution  shall be made unless (i) CMSI shall have been  advised by
each  Rating  Agency  that such  substitution  will not  negatively  affect  the
then-current  rating by such Rating Agency of the  CitiCertificates  or (ii) the
claims-paying  ability of the primary  mortgage  insurer is, at the time of such
substitution,  rated by each Rating Agency rating the  CitiCertificates at least
in the category of "AA" or its equivalent.

         Section 3.18.  Maintenance  of Hazard  Insurance,  Property  Protection
Expenses. CMSI shall cause to be maintained for each Mortgage Loan (other than a
Mortgage  Loan  relating  to a  cooperative  apartment)  hazard  insurance  with
extended  coverage  in an  amount  which  is at least  equal to (a) the  maximum
insurable value of the  improvements  securing such Mortgage Loan if such amount
is less than the unpaid principal  balance on the related Mortgage Loan, (b) the
principal  balance owing on such Mortgage Loan if such amount is greater than or
equal to 80% but is less than or equal to 100% of the insurable value or (c) 80%
of the insurable  value if principal  balance the Mortgage Loan is less than 80%
of the insurable value. Except in the case of cooperative apartments, CMSI shall
also  maintain  on property  acquired  upon  foreclosure,  or by deed in lieu of
foreclosure,  hazard fire insurance with extended coverage in an amount which is
at least  equal to the lesser of (a) the  maximum  insurable  value from time to
time of the  improvements  which are a part of such  property  or (b) the unpaid
principal  balance from time to time on such  Mortgage  Loan at the time of such
foreclosure or deed in lieu of foreclosure plus accrued interest at the Mortgage
Note Rate and the good-faith estimate of CMSI of related Liquidation Expenses to
be incurred in connection therewith. To the extent provided in Sections 3.10 and
3.04,  amounts  collected by CMSI under any such policies  shall be deposited in
the  Certificate  Account  (other  than in the case of CitiMae  Mortgage  Loans,
amounts to be applied to the  restoration  or repairs of the  related  Mortgaged
Property  or property  thus  acquired or amounts  released to the  Mortgagor  in
accordance with the Conduit Subservicer normal servicing  procedures).  Any cost
incurred by CMSI in maintaining any such insurance shall not, for the purpose of
calculating  monthly  distributions to the  Certificateholders,  be added to the
amount owing under the related Mortgage Loan,  notwithstanding that the terms of
the  Mortgage  Loan may so  permit.  Such  costs  shall be  recoverable  by CMSI
pursuant to Sections  3.04 and 3.16.  In cases in which  property  securing  any
Mortgage  Loan is located  in a  federally  designated  flood  area,  the hazard
insurance to be maintained for such Mortgage Low shaft include flood  insurance.
It is understood and agreed that no earthquake or other additional  insurance is
to be required of any Mortgagor or maintained on property acquired in respect of
a Mortgage Loan,  other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance. If
CMSI shall obtain and maintain a blanket policy  insuring  against hazard losses
on all of the Mortgage Loans, it shall  conclusively be deemed to have satisfied
its  obligations  as set forth in the first  sentence of this Section  3.16,  it
being understood and agreed that such policy may contain a deductible clause, in
which case CMSI shall, in the event that there shall not have been maintained on
the related  Mortgaged  Property a policy  complying  with the first sentence of
this Section,  and there shall have been a loss which would have been covered by
such policy, deposit in the Certificate Account the amount not otherwise payable
under the blanket policy because of such deductible clause.

         Section  3.19.  Assumption  and  Modification  Agreements  relating  to
Affiliated  Mortgage  Loans.  In any  case  in  which  property  relating  to an
Affiliated  Mortgage  Loan  subject  to a  Mortgage  has  been or is about to be
conveyed by the  Mortgagor,  CMSI shall  exercise  its right to  accelerate  the
maturity  of  such  Affiliated   Mortgage  Loan  under  any  due-on-sale  clause
applicable  thereto  to the  extent of its  contractual  arrangements  with such
Mortgagor.  If it is  prevented,  as  provided  in the  last  paragraph  of this
Section,  from enforcing any such clause or if the Affiliated Mortgage Loan does
not contain an enforceable due-on-sale provision,  CMSI is authorized to take or
enter into an assumption and  modification  agreement from or with the Person to
whom such  property has been or is about to be conveyed,  pursuant to which such
Person becomes liable under the related Mortgage Note and the Mortgagor  remains
liable  thereon;  provided,  that such  Affiliated  Mortgage  Loan as assumed or
modified meets the requirements set forth in this Pooling Agreement with respect
to the Affiliated  Mortgage Loans initially  included in the Trust Fund and that
the Affiliated  Mortgage Loan shall continue to be covered by my related Primary
Mortgage  Insurance  Certificate and hazard insurance policy.  CMSI shall notify
the Trustee that any assumption and modification agreement has been completed by
forwarding to the Trustee the original

                                       61
<PAGE>

copy thereof,  which copy shall be added by the Trustee or the Mortgage Document
Custodian  to the  related  Mortgage  File  and  shall,  for  all  purposes,  be
considered  a part of  such  Mortgage  File  to the  same  extent  as all  other
documents and  instruments  constituting a part thereof.  In connection with any
such  agreement,  the interest  rate of the related  Mortgage  Note shall not be
changed  nor shall any other term  affecting  the amount or timing of payment on
the Affiliated Mortgage Loan be changed.  Any fee collected by CMSI for entering
into  any  such  agreement  will be  retained  by CMSI as  additional  servicing
compensation.

         Notwithstanding  the  foregoing  paragraph of this Section or any other
provision of this Pooling Agreement,  CMSI shall not be deemed to be in default,
breach or any other  violation  of its  obligations  hereunder  by reason of any
assumption of an Affiliated  Mortgage Loan, or transfer of the property  subject
to a Mortgage without the assumption  thereof,  by operation of law or by reason
of  any  assumption  or  transfer  which  CMSI  reasonably  believes  it  may be
restricted by law from  preventing or which would result in  non-coverage of any
resulting loss that would otherwise be covered under the Mortgage Pool Insurance
Policy and any related Primary Mortgage  Insurance  Certificate,  for any reason
whatsoever.

         Section 3.20 Enforcement of Due-On-Sale Clauses, Assumption Agreements.
(a) When any Mortgaged  Property relating to a CitiMae Mortgage Loan is conveyed
by the  Mortgagor,  the Master  Servicer  shall enforce any  due-on-sale  clause
contained in any Mortgage Note or Mortgage that becomes  operative in accordance
with the terms of such  Mortgage  Note or  Mortgage,  as the case may be, to the
extent permitted under applicable law and governmental regulations,  but only to
the  extent  that such  enforcement  will not  adversely  affect  or  jeopardize
coverage under any insurance  policy.  Notwithstanding  the  foregoing,  (i) the
Master Servicer shall not be deemed to be in default wider this Section 3.20 (a)
by reason of any transfer or assumption  which the Master Servicer is restricted
by law from  preventing and (ii) if the Master  Servicer  determined  that it is
reasonably likely that any Mortgagor will bring, or if any Mortgagor does bring,
legal action to declare invalid or otherwise avoid  enforcement of a due-on-sale
clause contained in any Mortgage Note or Mortgage, the Master Servicer shall not
be required to enforce the due-on-sale clause or to contest such action.

         (b) Subject to the Master  Servicer's  duty to enforce any  due-on-sale
clause as provided  above,  if a CitiMae  Mortgage Loan contains no  due-on-sale
clause or the Master Servicer is prevented, as provided in Section 3.20(a), from
enforcing  any such clause,  the Master  Servicer is authorized to take or enter
into an assumption  and  modification  agreement from or 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 and the Mortgagor remains liable thereon.
The  Master  Servicer  shall  not take or enter  into  any such  assumption  and
modification   agreement,   however,   unless  such  transferee   satisfies  the
underwriting  standards  set forth in the Guide and  provided  that the coverage
required  under  any  insurance  policy  will  not  be  adversely   affected  or
jeopardized and unless (to the extent practicable in the circumstances) it shall
have received  confirmation  of the continued  effectiveness  of any  applicable
Primary Mortgage  Insurance  Certificate or hazard insurance policy.  The Master
Servicer shall notify the Trustee that any assumption and modification agreement
has been completed by forwarding to the Trustee the original copy thereof, which
copy shall be added by the Trustee to the related  Mortgage File and shall,  for
all  purposes,  be considered a part of such Mortgage File to the same extent as
all other documents and instruments  constituting a part thereof.  In connection
with any such agreement, no changes to the interest rate, principal balance, the
monthly  installment or any material  payment term of the Mortgage Loan shall be
made,  and any fee collected by the Conduit  Servicer for entering into any such
agreement  will be  retained  by the Master  Servicer  as  additional  servicing
compensation.

         Section 3.21.  Realization on Defaulted  Mortgage Loans. CMSI shall use
its  best  efforts,  consistent  with its  customary  servicing  procedures,  to
foreclose  upon or otherwise  comparably  convert the  ownership  of  properties
securing such of the Mortgage  Loans as come into and continue in default and as
to which no satisfactory  arrangements  can be made for collection of delinquent
payments pursuant to Section 3.01. Consistent with the foregoing, CMSI shall use
reasonable  efforts to realize upon  defaulted  Mortgage Loans in 

                                       62
<PAGE>

such  manner as will  maximize  the  receipt of  principal  and  interest by the
Certificateholders,  taking  into  account,  among other  things,  the timing of
foreclosure  proceedings.  In the event a deficiency action is available against
the  Mortgagor or any other  person,  CMSI may proceed for the  deficiency.  The
Servicer or Master Servicer may retain  twenty-five  percent of the net proceeds
received from a Mortgagor  pursuant to a deficiency  action as compensation  for
entering  into  such  deficiency   action.   Foreclosure  on  shares  issued  by
cooperative  housing  corporations  shall  be by sale  in  accordance  with  the
provisions  of  Article  9 of the  Uniform  Commercial  Code  in  effect  in the
applicable jurisdiction.

         In the event  that  title to any  Mortgaged  Property  is  acquired  in
foreclosure or by deed in lieu of  foreclosure,  the deed or certificate of sale
shall be issued to the  Trustee,  or to Its nominee on behalf of the Trust Fund.
Notwithstanding  any such  acquisition of title and  cancellation of the related
Mortgage Loan,  such Mortgage Low shall (except for purposes of Section 9.01) be
considered  to be an  Outstanding  Mortgage  Loan  such  time  as the  Mortgaged
Property  shall  be sold and such  Mortgage  Loan  becomes  a  Liquidated  Loan.
Consistent with the foregoing for purposes of all calculations hereunder so long
as such Mortgage Loan shall be considered to be an Outstanding Mortgage Loan, it
shall be assumed that the related Mortgage Note and its amortization schedule in
effect  on and after  such  acquisition  of title  (after  giving  effect to any
previous Principal  Prepayments,  and before any adjustment thereto by reason of
any Deficient  Valuations and Debt Service  Reductions or any similar proceeding
or  any  moratorium  or  similar  waiver  or  grace  period)  remain  in  effect
(notwithstanding that the indebtedness evidence by such Mortgage Note shall have
been  discharged),  subject to  adjustment  to reflect  the  application  of REO
Proceeds  received in any month. Net REO Proceeds received in any month shall be
deemed to have been  received  first in payment  of the  accrued  interest  that
remained unpaid on the date that such Mortgage Loan became an REO Mortgage Loan,
with the excess  thereof,  if any, being deemed to have been received in respect
of the  delinquent  principal  installments  that remained  unpaid on such date.
Thereafter,  Net REO  Proceeds  received  in any month  shall be  applied to the
payment of installments of principal and accrued  interest on such Mortgage Loan
deemed to be due and payable in accordance  with the terms of such Mortgage Note
and  such  amortization  schedule.  If such  Net REO  Proceeds  exceed  the then
delinquent principal and interest installments on such Mortgage Loan, the excess
shall be treated as a Principal  Prepayment received in respect of such Mortgage
Loan.

         In connection  with any Liquidated Loan as to which CMSI has accepted a
deed in lieu of foreclosure, CMSI shall dispose of such Mortgaged Property prior
to two years  after its  acquisition  by the  Lower-Tier  REMIC  unless  (i) the
Trustee  shall have been  supplied with an Opinion of Counsel to the effect that
the holding by the  Lower-Tier  REMIC of such Mortgaged  Property  subsequent to
such two-year  period (and specifying the period beyond such two-year period for
which the Mortgaged  Property may be held) will not result in the  imposition of
taxes on "prohibited  transactions"  of the Lower-Tier  REMIC as defined in Code
Section 860F, or cause the Lower-Tier  REMIC or the Upper-Tier  REMIC to fail to
quality, as a REMIC at any time that any  CitiCertificates  are Outstanding,  in
which  case the  Lower-Tier  REMIC may  continue  to hold such  until  Mortgaged
Property  (subject to any conditions  contained in such Opinion of Counsel),  or
(ii) CMSI shall have  applied  for,  prior to the  expiration  of such  two-year
period, an extension of such two-year period in the manner  contemplated by Code
Section  856(e)(3),  in which case the two-year  period shall be extended by the
applicable period. Notwithstanding any other provision of this Agreement, unless
otherwise  required  pursuant to  applicable  state law, no  Mortgaged  Property
acquired by the Lower-Tier  REMIC shall be (x) rented (or allowed to continue to
be rented) or otherwise used for the production of income by or on behalf of the
Lower-Tier  REMIC in such a manner or pursuant to any terms that would (1) cause
such Mortgaged Property to fall to qualify at any time as "foreclosure property"
within the meaning of Code Section 860G(a)(8),  (2) subject the Lower-Tier REMIC
to the  imposition  of any  federal or state  income  taxes on "net  income from
foreclosure  property" earned from such Mortgaged Property within the meaning of
Code Section 860G(c), or (3) cause the sale of such Mortgaged Property to result
in the receipt by the Lower-Tier REMIC of any income from  non-permitted  assets
as  described  in Code  Section  860F(a)(2)(B)  or (y)  sold in such  manner  or
pursuant to any terms that would subject the Lower-Tier  REMIC or the Upper-Tier
REMIC to the imposition of any federal or state income taxes on "net income from
foreclosure  property" within

                                       63
<PAGE>

the meaning of Code Section  860G(c),  unless CMSI has agreed to  indemnify  and
hold harmless the Lower-Tier  REMIC and the Upper-Tier REMIC with respect to the
imposition of any such taxes.

         The  foregoing is subject to the  provision  that, in any case in which
property  subject to a Mortgage  shall have  suffered  damage,  whether  from an
Uninsured Cause or otherwise, CMSI shall not be required to expend its own funds
in connection  with any  foreclosure or towards the restoration of such property
unless it shall  determine in its  discretion (a) that such  restoration  and/or
foreclosure  will  increase  the net  proceeds  of  liquidation  of the  related
Mortgage Loan to the  Certificateholders  after reimbursement to itself for such
expenses and (b) that such expenses will be  recoverable  by CMSI through either
Liquidation  Proceeds or Insurance  Proceeds  (with  respect to each of which it
shall have priority for purposes of  withdrawals  from the  Certificate  Account
pursuant to Section 3.16 from the related  property,  as contemplated in Section
3.16.) CMSI shall be responsible for all other costs and expenses incurred by it
in any  such  proceedings;  provided,  however,  that it shall  be  entitled  to
reimbursement  thereof from the related  property,  as  contemplated  in Section
3.16.  Notwithstanding  the above,  CMSI shall not be entitled to recover  legal
expenses incurred in connection with liquidation proceedings where the Mortgagor
pays all delinquent  payments and expenses and such  proceedings  are terminated
prior to  liquidation,  other than sums  received  from the  Mortgagor  for such
expenses.

         Notwithstanding  anything to the  contrary  contained  in this  Section
3.21,  the Servicer  shall be under no obligation to foreclose upon or otherwise
convert  the  ownership  of any  Mortgaged  Property  which it  believes  may be
contaminated with or affected by pollutants, contamination,  hazardous wastes or
hazardous substances. The Servicer shall not be liable to the Certificateholders
if,  based on its  belief  that no such  contamination  or  effect  exists,  the
Servicer  forecloses on a Mortgaged  Property and takes title to such  Mortgaged
Property,  and  thereafter  such  Mortgaged  Property  is  determined  to  be so
contaminated or affected.

         In the event CMSI does not elect to foreclose on a Mortgaged  Property,
CMSI  may,  in the  exercise  of its  judgment,  elect to  accept a  payment  or
payments,  in  connection  with  the  sale by the  Mortgagor  of such  Mortgaged
Property or the  retention  by the  Mortgagor  of such  Mortgaged  Property,  in
aggregate amount less than the outstanding  balance of the related Mortgage Loan
and accrued interest thereon.

         The Trustee  shall  furnish  CMSI with any powers of attorney and other
documents  necessary,  or appropriate to enable CMSI to carry out its efforts in
realizing upon defaulted Mortgage Loans hereunder.

         Section 3.22. Trustee to Cooperate; Release of Mortgage Files. Upon the
payment  in  full  of any  Mortgage  Loan  or  upon  the  receipt  by  CMSI of a
notification  that  payment in full will be escrowed in a manner  customary  for
such purpose, CMSI will immediately notify the Trustee by a certification (which
certification shall include a statement to the effect that all amounts received,
and all amounts  required to be paid by CMSI pursuant to either  Section 3.03 or
3.14 hereof,  in connection with such payment which are required to be deposited
to the Certificate Account pursuant to Section 3.03 or 3.14 have been or will be
so  deposited) of a Servicing  Officer and shall  request  delivery to it of the
Mortgage File. Upon receipt of such certification and request, the Trustee shall
promptly release or cause the Mortgage Document Custodian to release the related
Mortgage Documents to CMSI. Upon any such payment in full, CMSI is authorized to
execute,  pursuant to the authorization  contained in Section 3.10, 3.11 or 3.14
as applicable,  an instrument of  satisfaction  regarding  such Mortgage,  which
instrument of  satisfaction  shall be recorded by CMSI if required by applicable
law and be delivered to the Person  entitled  thereto,  it being  understood and
agreed  that  no  expenses  incurred  in  connection  with  such  instrument  of
satisfaction shall be withdrawn from the Certificate Account.  From time to time
and as  appropriate  for the  servicing or  foreclosure  of any  Mortgage  Loan,
including  for this  purpose  collection  under any Primary  Mortgage  Insurance
Certificate, the Trustee shall, upon request of CMSI and delivery to the Trustee
of a receipt  signed  by a  Servicing  Officer,  release  or cause the  Mortgage
Document  Custodian to release the related Mortgage  Documents to CMSI and shall
execute such  documents as shall be  necessary  to the  prosecution  of any such
proceedings.  Such receipt shall obligate CMSI to return the Mortgage  Documents
to the Trustee or the Mortgage

                                       64
<PAGE>

Document Custodian, as the case may be, when the need therefor by CMSI no longer
exists  unless the Mortgage  Loan shall have been prepaid or  liquidated  in the
interim,  in which case,  upon receipt of a certificate  of a Servicing  Officer
similar to that  hereinabove  specified  to such  effect,  the receipt  shall be
released by the Trustee to CMSI.

         Section 3.23.  Servicing Fee,  Payment of Certain  Expenses by CMSI. In
lieu of receiving the Servicing Fee for the  Affiliated  Mortgage Loans pursuant
to Section 3.04(c), CMSI as Servicer shall be entitled,  prior to the payment of
the amounts  described in Section 3.04(b),  to withhold and pay to itself out of
each payment  received by it on account of interest on each Affiliated  Mortgage
Loan  (subject to the other  provisions  of this Section) up to an amount which,
when  deducted,  will make the portion of interest on each  Affiliated  Mortgage
Loan being deposited in the Certificate  Account for the applicable period equal
to the  Pass-Through  Rate.  In addition,  CMSI shall be entitled to receive the
Servicing Fee out of Liquidation Proceeds or Insurance Proceeds, in each case to
the extent permitted by Section 3.16. Any Servicing Fee payable to CMSI pursuant
to this Section  shall be payable prior to any other  distributions  pursuant to
Article XII. Prepayment charges,  assumption fees, late payment or other similar
charges  shall be retained by CMSI as  additional  servicing  compensation.  Any
amounts  that CMSI  shall be  required  to deposit  in the  Certificate  Account
pursuant to Section  3.25 shall be deemed to reduce the  Servicing  Fee to which
CMSI is entitled pursuant to this Section.

         CMSI as Master Servicer for the CitiMae Mortgage Loans. as compensation
for its activities hereunder,  shall be entitled to receive on each Distribution
Date an amount with respect to each CitiMae  Mortgage Loan as to which a monthly
installment  of principal and interest has been received equal to one-twelfth of
the Master  Servicing Fee Rate for such Mortgage Loan multiplied by the Adjusted
Balance on which such installment of interest accrued.

         As compensation for its activities under its Servicing Agreements, each
Conduit  Servicer  shall be entitled to an amount with  respect to each  CitiMae
Mortgage  Loan as to which a monthly  installment  of principal and interest has
been received equal to  one-twelfth  of the Conduit  Servicing Fee Rate for such
Mortgage Loan  multiplied by the Adjusted  Balance on which such  installment of
interest accrued. Each Conduit Servicer is required to pay all expenses incurred
by it in connection with its servicing  activities under its Servicing Agreement
(including   advance  payment  of  premiums  for  Primary   Mortgage   Insurance
Certificates,  if required) and shall not be entitled to reimbursement  therefor
except as specifically  provided in the Servicing Agreement and not inconsistent
with this Agreement.

         CMSI shall be required to pay all expenses incurred by it in connection
with its  activities  hereunder  and  shall  not be  entitled  to  reimbursement

         Section 3.25.  Payments by CMSI.  CMSI shall deposit in the Certificate
Account not later than the  Distribution  Date in the month next  succeeding the
month in which  Principal  Prepayments  are received the amount set forth in the
next paragraph.

         For Affiliated  Mortgage Loans CMSI as Servicer shall deposit an amount
equal to the  difference  between  (a) the  product  of (i) all  such  Principal
Prepayments related to the Affiliated Mortgage Loans received in the month prior
to the month in which the Distribution  Date for such  Determination  Date falls
and (ii) the Pass Through Rate divided by (iii) 12 (calculated on the basis of a
360-day  year,  each month being assured to have 30 days) less (b) the amount of
interest on such Principal  Prepayments related to the Affiliated Mortgage Loans
required to be paid by the Mortgagors  (adjusted to the Pass-Through Rate). Such
deposit  shall be paid from,  and limited to, the  Servicing  Fee received  with
respect to scheduled  interest payments due on the Affiliated  Mortgage Loans on
the Due Date in the month in which such  Distribution  Date occurs or  Principal
Prepayments  related to the Affiliated  Mortgage Loans received in the preceding
calendar  month and other  Servicing  Fees received with respect to the calendar
month preceding the month in which such Distribution  Date occurs.  Such deposit
shall be applied first to interest with respect to partial Principal Prepayments
related to the Affiliated  Mortgage Loans and second to interest with respect to
Principal  Prepayments related to the Affiliated Mortgage Loans in full. No such
deposit shall be considered to be a Voluntary Advance by CMSI or be reimbursable
to CMSI, from cash in the Certificate Account or otherwise.

         For each CitiMae  Mortgage Loan CMSI, as Master  Servicer shall deposit
an amount  equal to (x) the amount by which the annual  interest  at the related
Mortgage  Note Rate (net of the related  Expense  Rate) on the prepaid  Adjusted
Balance of such CitiMae Mortgage Loan divided by twelve exceeds (y) the interest
required to be paid by Mortgagor from the due date of the last scheduled payment
of principal  and interest on such  Mortgage Low to the date of such  prepayment
(adjusted to the Mortgage Note Rate (net of the related Expense Rate). Not later
than the Distribution Date immediately  succeeding such Determination  Date, the
Master Servicer shall deposit in the Certificate  Account from its own funds the
amount  determined  by  aggregating,  for each such  Mortgage Loan for which the
amount determined  pursuant to (x) above exceeds the amount determined  pursuant
to (y) above less any CitiMae  Prepayment  Interest  Shortfall  allocated to the
Retained Fixed Yield, the amount of each such excess,  but only to the extent of
(and in reduction of) the Master  Servicer Fee payable to it pursuant to Section
3.23 for the calendar month in which such prepaid principal balance is received.

         Section 3.26 Refinancings of Mortgage Loans. In addition to waivers and
arrangements  permitted  by  Section  3.01,  CMSI  reserves  the  right to offer
refinancings of any Affiliated  Mortgage Loan or CitiMae  Mortgage Loan, if such
refinancing  arises out of a request by the related  Mortgagor for a refinancing
or a  modification,  or for other  relief  from the  provisions  of the  related
Mortgage Loan.

         On the Deposit Date in the month next  following the effective  date of
the  refinancing  of any  Mortgage  Loan  pursuant to this  Section,  CMSI shall
deposit,  or cause to be deposited,  into the Collection Account an amount equal
to the  prepayment in full of such Mortgage Loan (net of all Voluntary  Advances
and  Trustee  Advances  with  respect  to such  Mortgage  Loan,  which  shall be
reimbursed to the Trustee or deemed reimbursed to CMSI, as the case may be) and,
upon receipt by the Trustee of written notification of such deposit signed by an
Authorized Officer of CMSI, the related Mortgage File shall be released, and the
Trustee shall comply with the provisions of Section 3.22.

         For the  purposes of this  Section,  a  "refinancing"  will include any
process  with a  Mortgagor  that  results  in the  refinanced  Mortgage  Loan be
identified  and  serviced  as a "new  mortgage  loan" in the books,  records and
servicing files of the Servicer.

         Section 3.27.  Two-Tier REMIC  Structure;  General.  Elections shall be
made to treate the Trust Fund formed  hereunder as, and the affairs of the Trust
Fund  shall be  conducted  so as to  qualify it as,  two  separate

                                       66
<PAGE>

REMICs (the "Lower-Tier REMIC" and the "Upper-Tier  REMIC",  respectively),  for
federal  income tax purposes.  CMSI and the Trustee  agree to assure  continuing
treatment  of the  Trust  Fund  as two  separate  REMICs  and to  carry  out the
covenants set forth in Article XII and the  elections and reporting  required in
Section 3.07 on behalf of each of the  Lower-Tier  REMIC and  Upper-Tier  REMIC,
including  making  the  appropriate  elections  to treat the  Trust  Fund as two
separate  REMICs and  maintaining  two  segregated  accounts  (the  "Certificate
Account" and the "Upper-Tier REMIC Account", respectively).

         Section 3.28. The Certificate Account and the Upper-Tier REMIC Account.
CMSI, on behalf of the Trustee,  shall deposit daily in the Certificate  Account
in  accordance  with  Section 3.02 all  Remittances  received by it, any amounts
required to be deposited in the  Certificate  Account  pursuant to Section 3.01,
all other  deposits  required to be made to the  Certificate  Account other than
those amounts  specifically  designated to be deposited in the Upper-Tier  REMIC
Account in this Section 3.28 and all investments  made with moneys on deposit in
the Certificate Account, including all income or gain from such investments,  if
any. Funds on deposit in the  Certificate  Account shall be held and invested in
accordance with the applicable  provisions of Section 3.02.  Distributions  from
the  Certificate  Account  shall be made in  accordance  with the  provisions of
Sections 3.04, 3.16 and Articles XII and XIII to make payments in respect of the
Lower-Tier  Classes and to pay the  Servicing  Fee in  accordance  with  Section
3.03(c).

         Notwithstanding   anything   herein   to   the   contrary,   Upper-Tier
Certificates  shall not  receive  distributions  directly  from the  Certificate
Account.  On each  Distribution  Date,  CMSI,  on behalf of the  Trustee,  shall
withdraw  from the  Certificate  Account  and  deposit in the  Upper-Tier  REMIC
Account all  distributions  to be made on such  Distribution  Date in respect of
interest on and in reduction of Stated  Amount of the Class L Regular  Interest.
The Trustee shall cause to be distributed from the Upper-Tier REMIC Account,  to
the extent funds are on deposit therefor, all amounts required to be distributed
with  respect to the  Upper-Tier  Certificates  as specified in Articles XII and
XIII.

         To the  extent  that  any  part  of the  Upper-Tier  REMIC  Account  is
designated in Article XII as an Investment  Account,  the  provisions in Section
3.02 hereof  applicable to the investment of funds shall apply to the Upper-Tier
REMIC Account. In addition, the provisions of Section 3.02(b) shall apply to the
Upper-Tier REMIC Account.

ceased to be so  authorized  prior to the  authentication  and  delivery of such
Certificates or did not hold such offices at the date of such  Certificates.  No

in the form of one or more  typewritten  certificates,  to be  delivered  to the
initial Clearing Agency, by, or on behalf of, the Issuer. Such  CitiCertificates
shall  initially be  registered on the  Certificate  Register in the name of the
nominee of the initial Clearing  Agency,  and no Beneficial Owner will receive a
definitive   certificate   representing  such  Beneficial  Owner's  int  in  the
Book-Entry  Certificates,  except as provided in Section 5.06.  Unless and until

Certificates   and  the  taking  of  actions  by  the   Holders  of   Book-Entry
Certificates) as the authorized representative of the Beneficial Owners;

                 (iii) to the extent that the provisions of this Section 5.01(b)
conflict with any other  provisions of this  Agreement,  the  provisions of this
Section 5.01(b) shall control;

                 (iv) the rights of  Beneficial  Owners shall be exercised  only

         For purposes of any provision of this Agreement requiring or permitting
actions  with the  consent of, or at the  direction  of,  Holders of  Book-Entry
Certificates  evidencing  specified voting interests,  such direction or consent
shall be given by Beneficial Owners having the requisite percentage interests.

         Unless and until Definitive Certificates have been issued to Beneficial
Owners pursuant to Section 5.06, copies of the reports or statements referred to
in Section 3.05 shall be available to Beneficial  Owners upon written request to
the Trustee at the Corporate Trust Office.

         Section 5.02.  Registration  of Transfer and Exchange of  Certificates.
CMSI shall maintain or cause to be maintained in accordance  with the provisions
of Section  6.05 a  Certificate  Register in which,  subject to such  reasonable
regulations  as it may  prescribe,  CMSI shall provide for the  registration  of
Certificates and of transfers and exchanges of Certificates as herein provided.

         Upon surrender for  registration  of transfer of any Certificate at the
office or agency maintained by CMSI set forth in Article XII, CMSI shall execute
and the Trustee or the Authenticating  Agent shall authenticate and deliver,  in
the  name  of  the  designated  transferee  or  transferee,   one  or  more  new
Certificates in authorized  denominations of the same aggregate number of Single
Certificates or the same aggregate Percentage Interest, as the case may be.

         At the option of the Certificateholder,  Certificates may, be exchanged
for other Certificates of authorized denominations evidencing the same aggregate
number of Single Certificates or the same aggregate Percentage Interest,  as the
case may be, upon  surrender  of the  Certificates  to be  exchanged at any such
office or agency.  Whenever any  Certificates  are so surrendered  for exchange,
CMSI shall execute and the Trustee or  Authenticating  Agent shall  authenticate
and deliver the Certificates which the Certificateholder  making the exchange is
entitled to receive. Every Certificate presented or surrendered for registration
of transfer or exchange shall be accompanied by a written instrument of transfer
in form  satisfactory to the Trustee,  CMSI and the  Certificate  Registrar duly
executed  by the Holder  thereof or his  attorney  duly  authorized  in writing.
Notwithstanding  the  foregoing,   no  transfer  or  exchange  of  any  Residual
Certificate  shall be made by the  Trustee or  Authenticating

                                       70
<PAGE>

Agent unless the  Certificateholder  making the  exchange has complied  with the
provisions  of  this  Agreement,   the  respective  Certificate  and  applicable
securities laws.

         No service  charge  shall be made for any  registration  of transfer or
exchange of the Certificates,  but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or governmental  charge that may be imposed
in connection with any transfer or exchange of Certificates.

         All Certificates  surrendered for registration of transfer and exchange
shall be  canceled  and,  subject to the record  retention  requirements  of the
Exchange Act, subsequently destroyed by the Trustee or, at its direction, by the
Certificate Registrar.

         CMSI and the Trustee will cause the Certificate Registrar to provide to
the Paying  Agent,  if the Paying Agent is not the  Certificate  Registrar,  not
later than the third  Business Day next  preceding the  Distribution  Date,  the
names and  addresses  of the  Certificateholders  as of the Record  Date and the
number of Single  Certificates or Percentage  Interest held of record by each of
them.

         Notwithstanding  the foregoing,  no legal or beneficial interest in all
or any  portion  of a  Residual  Certificate  may be  transferred,  directly  or
indirectly,  to a  "disqualified  organization"  win the meaning of Code Section
860E(e)(5),  or to an agent of a disqualified  organization (including a broker,
nominee,  or other middleman) (an "Agent") and any such purported transfer shall
be void and of no effect. Further, no legal or beneficial interest in all or any
portion of a Residual  Certificate  may be registered in the name of a Plan or a
Person investing the assets of a Plan (such Plan or Person an "ERISA  Prohibited
Holder")  or in the name of a  person  that is not (i) a U.S.  Person  or (ii) a
non-U.S.  Person that holds the  Residual  Certificate  in  connection  with the
conduct of a trade or business  within the United  States and has  furnished the
transferor and the Trustee with an effective  Internal Revenue Service Form 4224
or (iii) a non-U.S.  Person that has  delivered to both the  transferor  and the
Trustee an opinion of a nationally recognized tax counsel to the effect that the
transfer  of  the  Residual   Certificate  to  it  is  in  accordance  with  the
requirements  of the Code and the  regulations  promulgated  thereunder and that
such transfer of the Residual  Certificate  will not be disregarded  for federal
income tax purposes  (any such person who is not  described in clauses (i), (ii)
or (iii) above being  referred to herein as a  "Nonpermitted  Foreign  Holder").
CMSI  shall not  execute  and the  Trustee  or  Authenticating  Agent  shall not
authenticate  and deliver,  a new Residual  Certificate  in connection  with any
transfer  of a Residual  Certificate.  and neither  CMSI nor the  Trustee  shall
accept a surrender  for transfer or  registration  of transfer,  or register the
transfer of, any Residual  Certificate unless the transferor shall have provided
to CMSI and the  Trustee  an  affidavit,  substantially  in the form  marked  as
Appendix 1 hereto,  signed by the transferee,  to the effect that the transferee
is not such a disqualified organization, an agent for any entity as to which the
transferee  has  not  received  a  substantially  similar  affidavit,  an  ERISA
Prohibited  Holder or a Non-permitted  Foreign Holder,  accompanied by a written
statement  signed by the  transferor  to the effect that,  as of the time of the
transfer.  the transferor has no actual  knowledge that such affidavit is false.
Upon  notice by CMSI that any legal or  beneficial  interest in any portion of a
Residual  Certificate  has  been  transferred,  directly  or  indirectly,  to  a
disqualified  organization  or  an  Agent  in  contravention  of  the  foregoing
restrictions,  the Trustee shall furnish to the Internal Revenue Service and the
transferor of such Residual  Certificate or to such Agent, within 60 days of the
request  therefor by such  transferor or such Agent,  and CMSI agrees to provide
the  Trustee  with  the  computation  of.  such  information  necessary  to  the
application  of Code Section  860E(e) as may be required by the Code,  including
but riot limited to the present value of the total anticipated excess inclusions
with respect to such Residual Certificate (or portion thereof) for periods after
such transfer.  At the election of CMSI,  the  reasonable  cost of computing and
furnishing  such  information  may be charged to the  transferor  or such Agent;
however,  the Trustee and CMSI shall in no event be excused from furnishing such
information.  Every  holder of a  Residual  Certificate  shall be deemed to have
consented  to such  amendments  to the Pooling  Agreement  as may be required to
further  effectuate the  restrictions on transfer of Residual  Certificates to a
disqualified   organization,   an  Agent,  an  ERISA  Prohibited   Holder  or  a
Non-permitted Foreign Holder.

                                       71

         The affidavit  described in the preceding  paragraph shall also contain
the statement of the transferee that it (i) has  historically  paid its debts as
they have come due and intends to do so in the future,  (ii) understands that it
may  incur  liabilities  in  excess  of cash  flows  generated  by the  Residual
Certificate,  (iii)  intends to pay taxes  associated  with holding the Residual
Certificate  as  they  become  due and  (iv)  will  not  transfer  the  Residual
Certificate  to any person or entity that does not provide a similar  affidavit.
The transferor's statement to the Trustee accompanying the affidavit shall state
that the transferor has no knowledge or reason to know that the statements  made
by the  transferee  with  respect  to  clauses  (i) and  (iii) of the  preceding
sentence are false.  Each Residual  Certificate shall bear a legend referring to
the restrictions contained in this paragraph and the preceding paragraph.

         Notwithstanding the foregoing,  no transfer of a Class A-IO Certificate
or a Class B-3, Class B-4 and Class B-5 CitiCertificate or Residual  Certificate
may be made unless such Class A-IO  Certificate,  Class B-3, Class B-4 and Class
B-5  CitiCertificate  or Residual  Certificate has been registered under the Act
and applicable state securities or "blue sky" laws, or an exemption from the Act
and applicable state securities or "blue sky" laws is available.  Upon surrender
for registration of transfer of any Class A-IO Certificate, Class B-3, Class B-4
and Class B-5 CitiCertificate or Residual Certificate, (1) the Trustee shall not
accept  surrender for transfer or  registration  of transfer of, or register the
transfer  of, any Class  A-IO  Certificate,  Class B-3,  Class B-4 and Class B-5
CitiCertificate or Residual  Certificate and (2) CMSI shall not execute, and the
Trustee  shall not  authenticate  and deliver,  any new Class A-IO  Certificate,
Class B-3, Class B-4 and Class B-5  CitiCertificate  or Residual  Certificate in
connection with the transfer of any Class A-IO Certificate, Class B-3, Class B-4
and Class B-5  CitiCertificate or Residual  Certificate,  unless either (A) such
Class A-IO Certificate,  Class B-3, Class B-4 and Class B-5  CitiCertificate  or
Residual  Certificate  has been  registered  under the Act and applicable  state
securities  or  "blue  sky"  laws,  or  (B)  exemptions  from  the  registration
requirements of the Act and applicable  state  securities or "blue sky" laws are
available,  and the  transferee  delivers to the Issuer and the Trustee a letter
substantially  to the effect set forth in Exhibit E to this Agreement and (1) if
such transferee is not a "Qualified  Institutional  Buyer" within the meaning of
Rule 144A of the Act, and if so requested by CMSI,  in its sole  discretion,  an
opinion of counsel  acceptable to CMSI shall have been delivered to CMSI and the
Trustee to the effect that such transfer is in compliance with either  subclause
(A) or  subclause  (B) of this clause (i) of this Section  5.02;  or (2) if such
transfer  is  to a  non-institutional  investor,  unless  such  investor  is  an
accredited  investor (as defined in Regulation D under the Act), has a net worth
(exclusive of primary  residence) of at least $1,000,000 as confirmed in writing
to the Trustee.

         No transfer of a Class M  CitiCertificate  or a Class B CitiCertificate
may be made unless any proposed transferee (i) executes a representation  letter
in substantially  the form of Exhibit F hereto and in substance  satisfactory to
the Trustee and the Issuer either  stating (a) that it is not, and is not acting
on behalf of, any employee benefit plan subject to the fiduciary  responsibility
provisions  of ERISA or Section 4975 of the Code,  or a  governmental  plan,  as
defined in Section  3(32) of ERISA,  subject to any federal,  state or local law
("Similar  Law")  which is,  to a  material  extent,  similar  to the  foregoing
provisions of ERISA or the Code (collectively,  a "Plan") or using the assets of
any such Plan to effect such purchase or (b) it is an insurance  company and the
source of funds used to  purchase  the Class M  CitiCertificates  or the Class B
CitiCertificates  is an  "insurance  company  general  account" (as such term is
defined in Section V(e) of Prohibited  Transaction  Class  Exemption 95-60 ("PTE
95-60"), 60 Fed. Reg. 35925 (July 12, 1995) and there is no Plan with respect to
which the amount of such  general  accounts  reserves  and  liabilities  for the
contracts)  held by or on behalf of such Plan and all other Plans  maintained by
the same  employer (or  affiliate  thereof as defined in Section  V(a)(1) of PTE
95-60) or by the same  employer  (or  affiliate  thereof  as  defined in Section
V(a)(1) of PTE 95-60) or by the same  employee  organization,  exceed 10% of the
total of all reserves and  liabilities of such general  account (as such amounts
are  determined  under Section I(a) of PTE 95-60) at the date of  acquisition or
(ii)  provides an opinion of counsel in form and substance  satisfactory  to the
Trustee  and  the  Issuer  that  the   purchase  or  holding  of  such  Class  M

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 Master  Servicer,  Servicer,  CMSI or the
Trustee to any obligation in addition to those undertaken in this Agreement.

loss or  theft  of any  Certificate  and (b)  there is  delivered  to CMSI,  the
Certificate  Registrar  and the Trustee  such  security or  indemnity  as may be
required by them to save each of them  harmless,  then, in the absence of notice

such Certificate for the purpose of receiving  distributions pursuant to Section
3.03 and for all other purposes  whatsoever,  and neither CMSI, the Trustee, the
Certificate  Registrar  nor any agent of CMSI,  the  Trustee or the  Certificate
Registrar shall be affected by any notice to the contrary.

Addresses.  If the  Trustee  is not the  Certificate  Registrar  and at any time
requests CMSI or the  Certificate  Registrar in writing to provide a list of the
names  and  addresses  of  Certificateholders,  CMSI  will  furnish  or (if  the
Certificate Registrar is not CMSI) cause the Certificate Registrar to furnish to
the Trustee, within 15 days after receipt of a request, such list as of the most
recent Record Date, in such form as the Trustee may reasonably require. If three
or more  Certificateholders  (i) request  such  information  in writing from die
Trustee,  (ii) state that such  Certificateholders  desire to  communicate  with
other  Certificateholders  with respect to their rights under this  Agreement or
under the Certificates and (iii) provide a copy of the communication  which such
Certificateholders  propose to  transmit,  then the Trustee  shall,  within five
Business Days after the receipt of such request,  afford such Certificateholders
access during normal business hours to the most recent list held by the Trustee,
if any.  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

CMSI,  the  Certificate  Registrar nor the Trustee shall be held  accountable by
reason  of the  disclosure  of  any  such  information  as to  the  list  of the
Certificateholders   hereunder,   regardless  of  the  source  from  which  such
information was derived.

         Section 5.06. Definitive  Certificates.  If (i)(A) the Servicer advises
the Trustee in writing  that the  Clearing  Agency is no longer  willing or able
properly to discharge its  responsibilities  as  depository  with respect to the
Book-Entry  Certificates,  and (B) the  Servicer is unable to locate a qualified
successor, (ii) the Servicer, at its option, advises the Trustee in writing that
it elects to terminate  the  book-entry  system  through the Clearing  Agency or
(iii)  after  the  occurrence  of  dismissal  or  resignation  of the  Servicer,
Beneficial  Owners  representing an aggregate Stated Amount of not less than 51%

Trustee shall notify the Beneficial Owners,  through the Clearing Agency, of the
occurrence of any such event and of the availability of Definitive  Certificates
to Beneficial  Owners  requesting the same. Upon surrender to the Trustee by the
Clearing  Agency  of  the  CitiCertificates  held  of  record  by  its  nominee,

Beneficial  Owners  pursuant to Section  5.06,  the Trustee  shall have all such
notices and communications specified herein to be given to Holders of Book-Entry
Certificates to the Clearing Agency.

errors in  judgment,  provided,  however,  that neither CMSI 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

or  expense  incurred  by  reason  of  willful  misfeasance,  bad faith or gross
negligence  in the  performance  of duties  hereunder  or reckless  disregard of
obligations  and duties  hereunder.  CMSI shall not be under any  obligation  to
appear in,  prosecute or defend any legal action which is not  incidental to its
duties to service the Mortgage Loans in accordance with this Agreement and which
in its respective opinion may involve it in any expense or liability,  provided,
however, that CMSI may in its sole discretion undertake any such action which it

                                     DEFAULT

         Section 7.01.  Events of Default.  If any one of the  following  events
("Events of Default") shall occur and be continuing:

         (a) Any failure by CMSI, if CMSI is the Paying Agent,  to distribute to
Certificateholders  any  payment  required  under  the  terms of this  Agreement
(including  any  payment  required to be made by CMSI  pursuant to Section  3.25
hereof) or, if CMSI is not the Paving Agent,  to pay over or to cause to be paid
over to the Paying  Agent for such  distribution,  any payment so required or to

notice of such  failure  shall  have  been  given to CMSI by or on behalf of the
Trustee,  or to CMSI and the Trustee,  by the Holders of the Required  Amount of
the  Certificates  if CMSI  falls to  distribute  or remit the full  amount of a

required  payment or (B) 3 Business  Days after  written  notice of such failure
shall have been given to CMSI as provided  above if CMSI falls to  distribute or
remit the full  amount of a  required  payment  for any  reason  other than as a
result of an error in calculation; or

         (b)  Failure on the part of CMSI to  repurchase  any  Mortgage  Loan as
required pursuant to Section 2.02 or 2.03 or to reimburse any Trustee Advance as

Business  Days after the date upon which  written  notice of such failure  shall
have  been  given to CMSI by or on  behalf  of the  Trustee,  or to CMSI and the
Trustee, by the Holders of the Required Amount of Certificates; or

         (c)  Failure  on the part of CMSI duty to  observe  or  perform  in any
material  respect any other  covenants  or  agreements  of CMSI set forth in the
Certificates  or in this  Agreement,  which failure (A)  materially  affects the
rights of the Certificateholders and (B) continues unremedied for a period of 60
Business Days after the date on which written notice of such failure,  requiring
the same to be  remedied,  shall  have been given to CMSI by or on behalf of the
Trustee,  or to CMSI and the Trustee,  by the Holders of the Required  Amount of
CitiCertificates; or

         (d) The entry of a decree or order by a court or agency or  supervisory
authority  having  jurisdiction  in  the  premises  for  the  appointment  of  a

winding up or liquidation of its affairs, and the continuance of any such decree
or order unstayed and in effect for a period of 60 consecutive days; or

         (e) CMSI shall consent to the  appointment of a conservator or receiver
or liquidator in any insolvency  readjustment of debt,  marshaling of assets and
liabilities  or similar  proceedings of or relating to CMSI or of or relating to
substantially all of its property,  or CMSI shall admit in writing its inability
to pay its debts generally as they become due, file a petition to take advantage

then,  and in each and every such case, so long as an Event of Default shall not
have been  remedied,  the  Trustee  or the  Holders  of the  Required  Amount of
Certificates,  by notice  then given in  writing to CMSI (and to the  Trustee if
given by the Certificateholders) may terminate all of the rights and obligations
of CMSI as Servicer of the Affiliated  Mortgage Loans and as Master  Servicer of
the CitiMae  Mortgage  Loans under this  Agreement.  On and after the receipt by
CMSI of such  written  notice,  all  authority  and  power  of CMSI  under  this
Agreement,

                                       77
<PAGE>

whether with respect to the  Certificates  or the Mortgage  Loans or  otherwise,
shall pass to and be vested the Trustee pursuant to and under this Section 7.01;
and,  without  limitation,  the Trustee is hereby  authorized  and  empowered to
execute and deliver, on behalf of CMSI as attorney-in-fact or otherwise, any and
all documents and other  instruments,  and to do or accomplish all other acts or
things  necessary  or  appropriate  to effect  the  purposes  of such  notice of
termination,  whether to complete the transfer and  endorsement  of the Mortgage
Loans and related  documents or  otherwise.  CMSI agrees to  cooperate  with the
Trustee in effecting the termination of the  responsibilities and rights of CMSI
hereunder, including, without limitation, the transfer to the successor servicer
for the administration by it of all cash amounts which shall at the time be held
by CMSI for deposit,  or have been deposited by CMSI, in the Certificate Account
or Servicing  Account or which shall  thereafter be received with respect to the
Mortgage  Loans.  In addition to any other amounts  which are then payable,  or,
notwithstanding  the  termination  of its  activities  as  servicer  and  master
servicer of the Mortgage Loans,  may become payable to CMSI under this Agreement
CMSI shall be entitled to receive  out of any  delinquent  payment on account of
interest on a Mortgage Loan, due during the period prior to the notice  pursuant
to this  Section  7.01  which  terminates  the  obligation  and  rights  of CMSI
hereunder and received after such notice,  that portion of such payment which it
would have received if such notice had not been given.

         Section 7.02.  Trustee to Act;  Appointment of Successor.  On and after
the time CMSI receives a notice of  termination  pursuant to Section  7.01,  the
Trustee  shall be the  successor  in all  respects  to CMSI in its  capacity  as
servicer and master servicer under this Agreement and the transactions set forth
or provided for herein and shall be subject to all the responsibilities, duties,
limitations on liabilities  and liabilities  relating  thereto placed on CMSI by
the terms and provisions  hereof As  compensation  therefor,  the Trustee shall,
except as provided in Section  7.01, be entitled to such  compensation  (whether
payable out of the  Certificate  Account or  otherwise)  as CMSI would have been
entitled  to  hereunder  if no  such  notice  of  termination  had  been  given.
Notwithstanding  the above, the Trustee may, if it shall be unwilling so to act,
or shall,  if it is legally  unable so to act,  appoint,  or petition a court of
competent  jurisdiction to appoint,  any established housing finance institution
having a net worth of not less d $5,000,000 and approved as  seller/servicer  by
GNMA,  FNMA or FHLMC as the successor to CMSI hereunder in the assumption of all
or any part of the  responsibilities,  duties or liabilities of CMSI  hereunder.
The Trustee or successor to CMSI  appointed  hereunder  shall not,  however,  be
required to advance funds held in the  Certificate  Account or elsewhere,  or to
repurchase Mortgage Loans. Pending appointment of a successor to CMSI hereunder,
unless the Trustee is prohibited by law from so acting, the Trustee shall act in
such capacity as hereinabove  provided.  In connection with such appointment and
assumption,  the Trustee may make such arrangements for the compensation of such
successor out of payments on the Mortgage Loans as it and such  successor  shall
agree;  provided,  however, that no such compensation shall be in excess of that
permitted CMSI hereunder. The Trustee and such successor shall take such action,
consistent  with this  Agreement,  as shall be necessary to effectuate  any such
succession.

         Any successor to CMSI as servicer and master  servicer shall during the
term of its service as servicer and Master Servicer maintain in force the policy
or policies which CMSI is required to maintain pursuant to Section 6.07.

         Section 7.03. Notification to Certificateholders. Upon any, termination
or  appointment of a successor to CMSI pursuant to this Article VII, the Trustee
shall  give  or  cause  to  be  given  prompt  written  notice  thereof  to  the
Certificateholders  at their respective  addresses  appearing in the Certificate
Register.

occurred  (which has not been cured),  the Trustee  shall  exercise  such of the
rights and powers  vested in it by this  Agreement,  and use the same  degree of

the  circumstances  in the  conduct  of his  own  affairs.  If  the  Trustee  is
incorporated  or  organized  under the laws of the State of New York,  then,  in
considering  what  actions are or are not prudent in the  circumstances,  to the
extent applicable,  the Trustee shall consider the matters enumerated in Section

effect on the date of this Agreement,  and in addition, the Trustee shall comply
with the  provisions of  subdivisions  (3),(4) and (5) of Section 126 of the New
York Real Property Law, as such law is in effect on the date of this  Agreement,

opinions,  reports,  documents,  orders or other  instruments  furnished  to the
Trustee  which  are  specifically  required  to be  furnished  pursuant  to  any
provision  of this  Agreement,  shall  examine  them to  determine  whether they
conform to the requirements of this Agreement.

         No  provision  of this  Agreement  shall be  construed  to relieve  the
Trustee from liability for its own negligent  action,  its own negligent failure
to act or its own misconduct; provided, however, that:

         (a)  Prior to the  occurrence  of an Event of  Default,  and  after the
curing of all such  Events of Default  which may have  occurred,  the duties and
obligations of the Trustee shall be determined solely by the express  provisions
of this Agreement, the Trustee shall not be liable except for the performance of
such duties and obligations as are specifically set forth in this Agreement,  no
implied  covenants or obligations  shall be read into this Agreement against the
Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee
may conclusively  rely, as to the truth of the statements and the correctness of
the  opinions  expressed  therein,  upon  if any  certificates,  statements,  or
opinions  furnished to the Trustee and  conforming to the  requirements  of this
Agreement;

         (b) The Trustee shall not be personally liable for an error of judgment
made in good faith by a Responsible  Officer of the Trustee,  unless it shall be
proved that the Trustee was negligent in ascertaining the pertinent facts;

         (c) The Trustee  shall-not  be  personally  liable with  respect to any
action taken,  suffered or omitted to be taken by it in good faith in accordance
with the  direction  of the  Holders  of the  Required  Amount  of  Certificates
relating to the time,  method and place of  conducting  any  proceeding  for any
remedy available to the Trustee, or exercising any trust or power conferred upon
the Trustee, under this Agreement;

         (d) The  Trustee  shall not be charged  with  knowledge  of any default
(other than a default in payment to the Trustee)  specified in clauses (i), (ii)
and (iii) of Section 7.01 or an Event of Default under clause (iv) or (v) unless
a  Responsible  Officer of the Trustee  assigned to and working in the Corporate
Trust Office  obtains actual  knowledge of such failure or the Trustee  receives
written  notice of such failure at its  Corporate  Trust Office from CMSI or the
Holders of the Required Amount of Certificates.

         The  Trustee  shall not be  required to expend or risk its own funds or
otherwise  incur  financial  liability in the  performance  of any of its duties
hereunder,  or in the  exercise  of any of its  rights  or  powers,  if there is
reasonable  ground for  believing  that the  repayment of such funds or adequate
indemnity  against such risk or liability is not  reasonably  assured to it, mid
none of the provisions  contained in this  Agreement  shall in any event require
the Trustee to perform,  or be responsible for the manner of performance of, any
of the  obligations  of CMSI under this  Agreement,  except during such time, if
any, as the Trustee  shall be the  successor  to, and be vested with the rights,

refraining from acting upon any resolution,  Officer's Certificate,  certificate
of auditors or any other certificate,  statement,  instruments, opinion. report,
notice,  request,  consent,  order,  appraisal,  bond or other paper or document
believed by it to be genuine and to have been signed or  presented by the proper
party or parties;

         (b) The  Trustee may  consult  with  counsel and any Opinion of Counsel
shall be full and complete authorization and protection in respect of any action
taken or suffered  or omitted by it  hereunder  in good faith and in  accordance
with such Opinion of Counsel;

         (c) Whenever in the administration of this Agreement the Trustee or its
agent shall deem it desirable  that a matter be proved or  established  prior to
taking, suffering or omitting any action hereunder,  including any action by the
Trustee pursuant to Section 10.01 hereof, the Trustee or its agent (unless other
evidence be herein  specifically  prescribed) may request and, in the absence of
bad faith on its part, rely upon any Officer's Certificate;

         (d) The Trustee  shall be under no  obligation  to exercise  any of the
rights or powers vested in it by this  Agreement,  or to  institute,  conduct or
defend any litigation hereunder or in relation hereto, at the request,  order or
direction of any of the  Certificateholders,  pursuant to the provisions of this
Agreement,  unless  such  Certificateholders  shall have  offered to the Trustee
reasonable  security or indemnity  against the costs,  expenses and  liabilities
which may be  incurred  therein or  thereby;  nothing  contained  herein  shall,
however, relieve the Trustee of the obligations, upon the occurrence of an Event
of Default (which has not been cured), to exercise such of the rights and powers
vested in it by this Agreement,  and to use the same degree of care and skill in
their exercise as a prudent man would exercise or use under the circumstances in
the conduct of his own affairs;

         (e) The Trustee  shall not be  personally  liable for any action taken,
suffered or omitted by it in good faith and believed by it to be  authorized  or
within the discretion or rights or powers conferred upon it by this Agreement;

         (f) Prior to the occurrence of an Event of Default and after the curing
of all Events of Default which may have occurred, the Trustee shall not be bound
to make any  investigation  into the facts or matters stated in any  resolution,
certificate,  statement,  instrument, opinion, report, notice, request, consent,
order, approval bond or other paper or documents, unless requested in writing so
to do by the Holders of the Required Amount of Certificates;  provided, however,
that if the  payment  within a  reasonable  time to the  Trustee  of the  costs,
expenses  or  liabilities  likely  to be  incurred  by it in the  making of such
investigation is, in the opinion of the Trustee,  not reasonably  assured to the
Trustee  by the  security  afforded  to it by the terms of this  Agreement,  the
Trustee may require reasonable indemnity against such cost, expense or liability
as a  condition  to such  proceeding.  The  reasonable  expense  of  every  such
examination  shall  be paid by  CMSI  or,  if  paid  by the  Trustee,  shall  be
reimbursed by CMSI upon demand.  Nothing in this clause (vi) shall  derogate the
obligation  of CMSI to observe any  applicable  law  prohibiting  disclosure  of
information regarding the Mortgagors; and

                                       80

         (g) The Trustee may  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 this
Agreement.

The  recitals  contained  herein  and  in  the  Certificates   (other  than  the
certificate  of  authentication  on the  Certificates)  shall  be  taken  as the

of the  same.  The  Trustee  makes  no  representations  as to the  validity  or
sufficiency of this Agreement or of the Certificates (other than the certificate
of  authentication  on the  Certificates)  or of any  Mortgage  Loan or  related
document.  The Trustee shall not be  accountable  for the use or  application by
CMSI of any of the  Certificates or of the proceeds of such  Certificates or for
the use or  application  of any funds paid to CMSI in  respect  of the  Mortgage
Loans or  deposited in or withdrawn  from the  Certificate  Account or Servicing
Account by CMSI. The Trustee shall have no liability for any losses  incurred as
a result of (i) any failure of the Trust Fund to qualify as two REMICs, (ii) any
termination,  inadvertent  or otherwise,  of the status of the Trust Fund as two
REMICs,  (iii)  any tax on  prohibited  transactions  imposed  by  Code  Section
860F(a)(1), (iv) any tax on net income from foreclosure property imposed by Code
Section  860G(c),  (v) any tax on contributions to a REMIC after the Startup Day

included  in any  federal,  state  or local  income  tax or  information  return
prepared  pursuant to Section  3.06;  provided,  that the  Trustee  shall not be
excused  hereby from liability for its own  negligence,  bad faith or failure to
perform its duties as specified herein.

         Section  8.04.  Trustee  May  Own  Certificates.  The  Trustee  in  its
individual or any other  capacity may become the owner or pledgee of one or more
of the Certificates with the same rights as it would have if it were not Trustee

Trustee.

Co-Certificate  Registrar,  any Note Custodian,  Mortgage  Document,  Custodian,
Depository,  any Co-Paying Agent, any Authenticating Agent appointed pursuant to
Section  8.12 and any other agent of the Trustee  appointed  pursuant to Section
8.02 shall be paid by CMSI.  as  Servicer in  accordance  with  Article  XII. In
consideration  of paying the amounts payable pursuant to this Section 8.05, CMSI
may retain the Trustee Fee payable with respect to the CitiMae  Mortgage  Loans.
The  Trustee  (and  any  such  co-trustee)   shall  be  entitled  to  reasonable
compensation (which shall not be limited by any provision of law with respect to
the compensation of a trustee of an express trust) for all services  rendered by
them in the execution of the trust or trusts hereby  created and in the exercise
and  performance of any of the powers and duties  hereunder of the Trustee,  and
upon notice to CMSI,  the  Trustee  will be paid or  reimbursed  by CMSI for all
reasonable expenses,  disbursements and advances incurred or made by the Trustee
in  accordance  with any of the  provisions  of this  Agreement  (including  the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ)  except any such expense,  disbursement
or  advance  as may  arise  from  its  negligence  or bad  faith or which is the
responsibility of the Certificateholders hereunder.

         The Trustee, each Co-Certificate  Registrar,  each Note Custodian, each
Mortgage  Document  Custodian,  each  Depository,  each  Co-Paying  Agent,  each
Authenticating  Agent and any  agent  appointed  pursuant  to  Section  8.02 are
entitled to indemnification from CMSI, as Servicer or Master Servicer,  and will
be held  harmless  against  any loss,  liability  or  expense  incurred  without
negligence or bad faith on their part,  arising out of or in connection with the
acceptance or  administration  of the trust or trusts  hereunder,  including the
costs and  expenses of  defending  themselves  against any claim or liability in
connection  with the  exercise or  performance  of any of their powers or duties
hereunder.  Such  indemnification  shall survive the payment of the Certificates
and  termination  of the Trust Fund,  as well as the  resignation  or removal of
CMSI, as Servicer, (if such action which caused the need for the indemnification
occurred while CMSI acted as Servicer) and for purposes of such  indemnification

                                       81
<PAGE>

neither the  negligence  nor bad faith of any of the entities  enumerated in the
preceding  sentence shall be imputed to, or adversely  affect,  the right of any
other enumerated person to be entitled to indemnification.

         Section  8.06.  Eligibility   Requirements  for  Trustee.  The  Trustee
hereunder shall at all times be a corporation or a national banking association,
other than an Affiliate of CMSI,  having its principal  office in the same state
as that in which the initial  Trustee  under this  Agreement  has its  principal
office (or in the State of New York) and organized and doing  business under the
laws of such State or the United States of America,  authorized  under such laws
to exercise corporate trust powers,  having a combined capital and surplus of at
least  $30,000,000 and subject to supervision or examination by federal or state
authority. If such corporation or national banking association publishes reports
of condition at least  annually,  pursuant to law or to the  requirements of the
aforesaid  supervising  or  examining  authority,  then for the purposes of this
Section 8.06, the combined  capital and surplus of such  corporation or national
banking  association  shall be deemed to be its combined  capital and surplus as
set forth in its most recent  report of condition so  published.  In case at any
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section 8.06,  the Trustee shall resign  immediately in the manner and with
the effect specified in Section 8.07.

         Section 8.07. Resignation or Removal of Trustee. The Trustee may at any
time resign and be discharged  from the trusts hereby  created by giving written
notice thereof to CMSI.  Upon receiving such notice of  resignation,  CMSI shall
promptly appoint a successor Trustee by written  instrument , in duplicate,  one
copy of which  instrument  shall be delivered to the  resigning  Trustee and one
copy to the  successor  Trustee.  If no  successor  Trustee  shall  have been so
appointed  and having  accepted  appointment  within 30 days after the giving of
such notice of  resignation,  the  resigning  Trustee may  petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         If at any time the Trustee  shall  cease to be  eligible in  accordance
with the  provision  of  Section  8.06 and shall  fail to resign  after  written
request  therefor by CMSI, or if at any time the Trustee shall be legally unable
to act,  or shall be  adjudged a bankrupt  or  insolvent,  or a receiver  of the
Trustee or of its property shall be appointed,  or any public officer shall take
charge or control of the  Trustee or of its  property or affairs for the purpose
of rehabilitation,  conversion or liquidation, then CMSI may remove the Trustee.
If it removes the  Trustee  under the  authority  of the  immediately  preceding
sentence, CMSI shall promptly appoint a successor Trustee by written instrument,
in duplicate,  one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the 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 nonperformance of certain
actions by the Trustee,  the rating  assigned to the  CitiCertificates  would be
lowered or (d) if the credit  rating of the  Trustee  is  downgraded  to a level
which would result in the rating assigned to the CitiCertificates to be lowered;
or (ii) by the holders of  Certificates  evidencing  more than 50% of the Voting
Interest  of  the   CitiCertificates   and  the  Class  A-IO  Certificates  then
outstanding  and  more  than 50% of the  Percentage  Interests  of the  Residual
Certificates.

         Any  resignation  or  removal  of  the  Trustee  and  appointment  of a
successor  Trustee  pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

         Section 8.08.  Successor  Trustee.  Any successor  Trustee appointed as
provided in Section 8.07 shall execute,  acknowledge  and deliver to CMSI and to
its  predecessor  Trustee an instrument  accepting  such  appointment  hereunder
(including the duties of the Trustee, in its individual  capacity,  as stated in
Section  8.13 and, if  applicable,  Section  8.14  herein),  and  thereupon  the
resignation  or removal of the  predecessor  Trustee shall

                                       82
<PAGE>

become  effective and such successor  Trustee,  without any further act, deed or
conveyance,  shall become fully vested with all the rights,  powers,  duties and
obligations of its predecessor hereunder with like effect as if originally named
as Trustee.  The predecessor  Trustee shall deliver to the successor Trustee all
Mortgage Files and related  documents and statements held by it hereunder;  and,
if any Mortgage  Notes or Mortgage  Documents are then held by the Mortgage Note
Custodian or Mortgage Document Custodian, respectively,  pursuant to a Custodial
Agreement,  the  predecessor  Trustee and the  Mortgage  Note  Custodian  or the
Mortgage  Document  Custodian,  as the case may be,  shall amend such  Custodial
Agreement to make the successor Trustee the successor to the predecessor Trustee
thereunder;  and CMSI and the predecessor Trustee shall execute and deliver such
instruments and do other such things as may reasonably be required for fully and
certainly  vesting and  confirming  in the  successor  Trustee all such  rights,
powers, duties and obligations.

         No  successor  Trustee  shall  accept  appointment  as provided in this
Section 8.08 unless at the time of such acceptance such successor  Trustee shall
be eligible under the provisions of Section 8.06.

         Upon  acceptance of appointment  by a successor  Trustee as provided in
this  Section  8.08,  CMSI shall mail notice of the  succession  of such Trustee
hereunder  to all Holders of  Certificates  at their  addresses  as shown in the
Certificate  Register.  If CMSI fails to mail such  notice  within 10 days after
acceptance of appointment by the successor Trustee,  the successor Trustee shall
cause such notice to be mailed at the expense of CMSI.

         Section 8.09.  Merger or Consolidation  of Trustee.  Any corporation or
national  banking  association into which the Trustee may be merged or converted
or with which it may be  consolidated,  or any  corporation or national  banking
association resulting from any merger,  conversion or consolidation to which the
Trustee shall be a party,  or any  corporation or national  banking  association
succeeding to all or  substantially  all of the corporate  trust business of the
Trustee,  shall  be  the  successor  of the  Trustee  hereunder,  provided  such
corporation  or  national  banking  association  shall  be  eligible  under  the
provisions of Section 8.06,  without the execution or filing of any paper or any
further act on the part of any of the  parties  hereto,  anything  herein to the
contrary notwithstanding.

         Section  8.10.   Appointment   of   Co-Trustee  or  Separate   Trustee.
Notwithstanding  any other  provisions of this  Agreement,  at any time, for the
purpose of meeting any legal  requirements of any jurisdiction in which any part
of the Trust Fund or  property  securing  any  Mortgage  Note may at the time be
located,  CMSI and the  Trustee  acting  jointly  shall have the power and shall
execute and deliver all  instruments to appoint one or more Persons  approved by
the Trustee to act as co-trustee  or  co-trustees  jointly with the Trustee,  or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons,  in such  capacity and for the benefit of the
Certificateholders,  such title to the Trust  Fund,  or any part  thereof,  and,
subject to the other  provisions  of this Section  8.10,  such  powers,  duties,
obligations,  rights and trusts as CMSI and the Trustee may  consider  necessary
and desirable.  If CMSI shall not have joined in such appointment within 15 days
after  the  receipt  by it of a  request  so to do,  or in the  case an Event of
Default shall have occurred and be continuing,  the Trustee alone shall have the
power to make such  appointment.  No  co-trustee or separate  trustee  hereunder
shall be required to meet the terms of eligibility as a successor  trustee under
Section 8.06 and no notice to the  Certificateholders  of the appointment of any
co-trustee or separate trustee shall be required under Section 8.08.

         Every separate trustee and co-trustee shall, to the extent permitted by
law and by the instrument  appointing  such separate  trustee or co-trustee,  be
appointed and act subject to the following provisions and conditions:

         (a) All rights,  powers,  duties and  obligations  conferred or imposed
upon the Trustee  shall be conferred or imposed upon and  exercised or performed
by the  Trustee  and such  separate  trustee  or  co-trustee  jointly  (it being
understood  that such separate  trustee or  co-trustee is not  authorized to act
separately  without the  Trustee  joining  such act),  except to the extent that
under any law of any  jurisdiction in which any particular act

                                       83
<PAGE>

or acts are to be  performed  (whether as Trustee  hereunder  or as successor to
CMSI hereunder), the Trustee shall be incompetent or unqualified to perform such
act or acts,  in  which  event  such  rights,  powers,  duties  and  obligations
(including the holding of title to the Trust Fund or any portion  thereof in any
such  jurisdiction)  shall be exercised  and  performed  singly by such separate
trustee or co-trustee, but solely at the direction of the Trustee;

         (b) No trustee  hereunder shall be held personally  liable by reason of
any act or omission of any other trustee hereunder; and

         (c) CMSI and the  Trustee  acting  jointly  may at any time  accept the
resignation of or remove any separate trustee or co-trustee.

         Any notice,  request or other  writing  given to the  Trustee  shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as  effectively  as if given to each of them.  Every  instrument  appointing any
separate  trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee,  upon its acceptance
of the trusts conferred,  shall be vested with the estates or property specified
in its instrument of appointment, either Jointly with the Trustee or separately,
as may be provided  therein,  subject to all of the provisions of this Agreement
relating to the conduct of, affecting the liability of, or affording  protection
to, the  Trustee.  Every such  instrument  shall be filed with the Trustee and a
copy thereof given to CMSI.

         Any separate  trustee or co-trustee  may, at any time,  constitute  the
Trustee,  its agent or attorney-in-fact,  with full power and authority,  to the
extent not  prohibited  by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name.  If any separate  trustee or co-trustee
shall die. become incapable of acting, resign or be removed, all of its estates,
properties,  rights,  remedies  and trusts shall vest in and be exercised by the
Trustee to the extent  permitted  by law,  without the  appointment  of a new or
successor trustee.

         Section 8.11. Tax Returns. The Trustee, upon request, will furnish CMSI
with all such  information as may be reasonably  required in connection with the
preparation of all federal, state and local income tax or information returns of
the Upper-Tier REMIC and the Lower-Tier REMIC.

         Section 8.12. Appointment of Authenticating Agent. At any time when any
of the Certificates remain outstanding the Trustee may appoint an Authenticating
Agent or Agents (which may include CMSI or any of its affiliates) which shall be
authorized  to act on behalf of the Trustee to  authenticate  Certificates,  and
Certificates so authenticated shall be entitled to the benefit of this Agreement
and shall be valid and  obligatory for all purposes as if  authenticated  by the
Trustee   hereunder.   Wherever   reference   made  in  this  Agreement  to  the
authentication  and  delivery of  Certificates  by the Trustee or the  Trustee's
certificate  of  authentication,  such  reference  shall be  deemed  to  include
authentication and delivery on behalf of the Trustee by an Authenticating  Agent
and a  certificate  of  authentication  executed  on behalf of the Trustee by an
Authenticating  Agent. Each Authenticating Agent shall be acceptable to CMSI and
shall at all times be a corporation or national  banking  association  organized
and doing  business  under the laws of the United  States of America,  any state
thereof  or the  District  of  Columbia,  authorized  under  such laws to act as
Authenticating  Agent,  having a combined  capital  and surplus of not less than
$15,000,000,  authorized  under such laws to do a trust  business and subject to
supervision or examination by federal or state authority. If such Authenticating
Agent publishes  reports of condition at least  annually,  pursuant to law or to
the  requirements  of said  supervising  or  examining  authority,  then for the
purposes  of this  Section  8.12,  the  combined  capital  and  surplus  of such
Authenticating  Agent shall be deemed to be its combined  capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of  this  Section  8.12,  such  Authenticating  Agent  shall  resign
immediately in the manner and with the effect specified in this Section 8.12.

                                       84
<PAGE>

         Any  corporation  or  national   banking   association  into  which  an
authenticating  Agent  may be  merged in or  converted  or with  which it may be
consolidated,  or any corporation or national banking association resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall
be a party, or any corporation or national banking association succeeding to the
corporate agency or corporate trust business of an Authenticating  Agent,  shall
continue to be an  Authenticating  Agent,  provided such corporation or national
banking association shall be otherwise eligible under this Section 8.12, without
the  execution  or  filing of any  paper or any  further  act on the part of the
Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to CMSI.  The Trustee may at any time  terminate  the
agency of an  Authenticating  Agent by giving  written  notice  thereof  to such
Authenticating Agent and to CMSI. Upon receiving such a notice of resignation or
upon such a termination,  or in case at any time such Authenticating Agent shall
cease to be eligible in accordance with the Authenticating  Agent which shall be
provisions of this Section 8.12, the Trustee may appoint a successor  acceptable
to CMSI and shall mail written notice of such  appointment by first-class  mail,
postage prepaid to all Certificateholders as their names and addresses appear in
the Certificate Register. Any successor  Authenticating Agent upon acceptance of
its appointment  hereunder  shall become vested with all the rights,  powers and
duties of its predecessor hereunder,  with like effect as if originally named as
an  Authenticating  Agent  herein.  No successor  Authenticating  Agent shall be
appointed unless eligible under the provisions of this Section 8.12.

         Any reasonable  compensation  paid to an  Authenticating  Agent for its
services  under this Section 8.12 shall be a  reimbursable  expense  pursuant to
Section 8.05 if paid by the Trustee.

         If an  appointment  is  made  pursuant  to  this  Section  8.  12,  the
Certificates may have endorsed thereon, in addition to the Trustee's certificate
of authentication,  an alternate  certificate of authentication in the following
form:

         "This is one of the  Certificates  referred to in the  within-mentioned
Agreement.


                             _______________________
                                   As Trustee


                            By_______________________
                              Authenticating Agent


                            By_______________________
                            Authenticating Signature"

(in its individual capacity and not as Trustee) shall deposit funds equal to the
Delinquency  Amount  for the  related  Determination  Date into the  Certificate
Account;  provided  that the  Trustee  (in such  individual  capacity)  shall be
obligated to make such deposit only to the extent of funds  determined by it (in
its sole discretion) to be recoverable from future  Remittances,  Net Recoveries
and other  proceeds  or  collections  on or in  respect of the  Mortgage  Loans,
provided,  however,  die Trustee may only recover funds for Delinquency  Amounts
relating  to  CitiMae   Mortgage   Loans  or  Affiliated   Mortgage  Loans  from
Remittances,  Net  Recoveries and other  proceeds  relating to CitiMae  Mortgage
Loans or Affiliated Mortgage Loans, respectively.  CMSI shall pay to the Trustee
a servicing  administration fee of $100 in respect of each Deposit Date on which
the Trustee (in such individual  capacity) makes such a deposit,  promptly after
CMSI receives  notice  thereof from the Trustee.  CMSI shall also  reimburse the
Trustee for the

                                       85
<PAGE>

amount of any such  deposit on the Business  Day CMSI  receives  notice from the
Trustee of the amount  thereof,  provided that if such notice is received  after
1:00 p.m.,  New York City time, on a Business Day, such  reimbursement  shall be
made to the Trustee on the next following Business Day, not later than 1:00 p.m.
To the extent the  Trustee  receives  an amount on or in respect of the  CitiMae
Mortgage Loans or Affiliated Mortgage Loans,  respectively,  identified to it as
being in respect of any such deposit, the Trustee shall repay to CMSI the amount
of such reimbursement not later than the Business Day after the Trustee receives
the same.  Promptly  after the Trust Fund is  terminated  pursuant to Article IX
hereof,  CMSI  shall  notify  the  Trustee  in  writing of the amount of Conduit
Trustee  Advances and Affiliated  Trustee  Advances that were not recovered from
future  Remittances,  Net  Recoveries or other  proceeds or collections on or in
respect  of  the  CitiMae   Mortgage   Loans  or  Affiliated   Mortgage   Loans,
respectively. The Trustee (in such individual capacity) shall reimburse CMSI for
the amount of Conduit  Trustee  Advances or Affiliated  Trustee  Advances not so
recovered  and  repaid to CMSI on the next  Business  Day after its  receipt  of
notice thereof. CMSI shall furnish to the Trustee such information within CMSI's
possession  with  respect to the Mortgage  Loans as the Trustee may require,  in
order to make a  determination  that any  advance  made by the  Trustee  will be
recoverable.

Account Trigger  Applicability  is specified in Article XII as applicable to the
CitiCertificates, then:

         (a) In the  event dig an  Advance  Account  Trigger  Date  occurs,  the
Servicer  will  notify  the  Trustee  in writing  of such  occurrence  and,  the
Servicer,  the Trustee,  in both its individual  capacity and as Trustee,  shall

its  individual  capacity,  shall pay to the  Advance  Account  Depository,  for

Advance from future Remittances, Net Recoveries or other proceeds or collections
or in respect of the CitiMae  Mortgage Loans or Affiliated  Mortgage  Loans,  as
provided  for in  this  Agreement  (the  aggregate  of  such  amounts  as to any
Distribution Date, the "Advance Account Reimbursement Amount").

         (e) On or  before  each  Distribution  Date  occurring  on or after the
Advance  Account  Funding Date,  the Servicer  shall pay, to the extent of funds
available,  to the Advance  Account by wire  transfer of  immediately  available
funds the Advance Account Reimbursement Amount with respect to such Distribution
Date as provided in the Agreement.

         (f) On each  Distribution  Date, the amount in the Advance Account will
be  reduced  and  released  to  the  extent  permitted  in the  Advance  Account
Depository Agreement.

         (g)  Notwithstanding  the foregoing,  an alternative  method of limited
support for the Trustee's obligation to make advances in respect of the Mortgage
Loans may be provided, if such change does not cause the then current ratings of
the  CitiCertificates or any outstanding Class or Subclass thereof to be lowered
by Moody's.

                                   TERMINATION

         Section 9.01. Termination upon Repurchase by CMSI or Liquidation of all
Mortgage Loans. The respective  obligations and responsibilities of CMSI and the
Trustee  created hereby and the Trust Fund created  hereby shall  terminate upon
(a) the  repurchase  by  CMSI  of all of the  Mortgage  Loans  and all  property
acquired in respect of any Mortgage Loan  remaining in the Trust Fund at a price
equal to the sum of (i) 100% of the Adjusted  Balance of each  Mortgage  Loan on
the first day of the month of  repurchase  (after  giving  effect to payments of
principal due on such first day) plus accrued  interest at the Investor Rate for
each  Mortgage  Loan to but not including the Due Date in the month in which the
related  distribution  is made to  Certificateholders,  after the  deduction  of
unreimbursed  Voluntary  Advances,  Advance  Account  Advances  (other than such
payments and  advances in respect of interest in excess of the Investor  Rate on
the Mortgage Loans,  Conduit Trustee  Advances and Affiliated  Trustee  Advances
made  prior to the  month of  repurchase,  whereupon  such  Voluntary  Advances,
Advance  Account  Advances  Conduit  Trustee  Advances  and  Affiliated  Trustee
Advances will be reimbursed to the Trustee or deemed  reimbursed to CMSI, as the
case may be, by such  deductions,  and (ii) the appraised  value of any acquired
property in the Trust Fund (less the good faith  estimate of CMSI of liquidation
expenses to be incurred in connection with its disposal thereof), such appraisal
to be conducted by an appraiser mutually agreed upon by CMSI and the Trustee, or
(b) the later of (i) the  maturity or other  liquidation  (or any  advance  with
respect  thereto) of the last Mortgage Loan  remaining in the Trust Fund and the
disposition  of all property  acquired  upon  foreclosure  or by deed in lieu of
foreclosure of any Mortgage Loan and (ii) the payment to the  Certificateholders
of all amounts in the Certificate  Account  required to be paid to them pursuant
to this Agreement;  provided,  however, that in no event shall the trust created
hereby  continue  beyond the  expiration  of 21 years from the death of the last
survivor of the lawful descendants of Joseph P. Kennedy,  the late Ambassador of
the United States of America to the Court of St. James's,  living on the date of
this  Agreement.  Such  termination  shall  occur  only  in  connection  with  a
"qualified  liquidation"  within  the  meaning  of Code  Section  860F(a)(4)(A),
pursuant  to which the  Trustee  shall sell or  otherwise  dispose of all of the
remaining  assets  of the  Trust  Fund and make all  required  distributions  to
Certificateholders  within  90  days  of  the  adoption  of a plan  of  complete
liquidation.  For this purpose, the notice of termination  described in the next
paragraph shall be the adoption of a plan of complete  liquidation  described in
Code  Section  860F(a)(4)(A)(i),  which shall be deemed to occur on the date the
first such notice is mailed.  Such date shall be specified in the final  federal
income  tax  return of each of the  Upper-Tier  REMIC and the  Lower-Tier  REMIC
constituted  by the  Trust  Fund.  The  right of CMSI to  repurchase  all of the
Mortgage  Loans on any  Distribution  Date pursuant to clause (a) above shall be
conditioned upon (A) the aggregate  Adjusted Balances of such Mortgage Loans, at
the time of any such repurchase and after giving effect to  distributions  to be
made on such  Distribution  Date,  aggregating  an  amount  less  than 5% of the
aggregate  Adjusted  Balance of the Mortgage Loans as of the Cut-Off Date, which
amount is set forth in Article XII and (B) any other  condition set forth in the
related Pooling Agreement.  Any other method of termination or repurchase of the
Trust Fund than as set forth  above must be based on the  receipt by the Trustee
of an Opinion of Counsel  (who may not be an employee of CMSI or of an Affiliate
of CMSI) or other evidence that such  termination and repurchase will be part of
a "qualified liquidation" within the meaning of Code Section 860F(a)(4)(A), will
not adversely  affect the status of the Trust Fund as two separate  REMICs under
the Code and will not otherwise subject the Trust Fund to any tax.

         Notice of any termination,  specifying the Distribution Date upon which
the  Certificateholders  may  surrender  their  Certificates  to the Trustee for
payment of the final  distribution and cancellation,  shall be given promptly by
the Trustee by letter to the Certificateholders  mailed not earlier than 30 days
nor  more  than 60 days  prior  to such  Distribution  Date  specifying  (A) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation   arid  surrender  of  the   Certificates  at  the  office  therein
designated,  (B) the amount of such final  payment  and (C) that the Record Date
otherwise applicable to such Distribution Date is not applicable, payments being
made only upon  presentation  and surrender of the Certificates at the office of
the

                                       88
<PAGE>

Paying Agent therein specified.  CMSI shall give such notice to the Trustee and,
if applicable,  the Certificate  Registrar,  the Mortgage Document Custodian and
the Paying Agent at the time such notice given to the Certificateholders. In the
event such notice is given, CMSI shall deposit in the Certificate Account or the
account  designated by the Paying Agent if CMSI is not the Paying Agent,  on the
Business Day next  preceding  the  Distribution  Date with respect to such final
distribution,   an  amount  equal  to  the  final  payment  in  respect  of  the
Certificates. Upon certification to the Trustee by an Authorized Officer of CMSI
following such final  deposit,  and delivery by CMSI of an Opinion of Counsel to
the effect that all  conditions  set forth in this Article IX have been met, the
Trustee  shall  promptly  release to CMSI the  Mortgage  Files for the  Mortgage
Loans.  Any such  repurchase  shall occur only during the month of, and prior to
the Determination  Date relating to, the Distribution Date on which such amounts
will be distributed to Certificateholders.

         In the event  that all of the  Certificateholders  shall not  surrender
their  Certificates for cancellation  within six months after the date specified
in the  above-mentioned  written notice, the Trustee shall give a second written
notice to the remaining  Certificateholders  to surrender their Certificates for
cancellation and receive the final distribution with respect thereto.  If within
one year  after  the  second  notice  all the  Certificates  shall not have been
surrendered for  cancellation,  the Trustee may take  appropriate  steps, or may
appoint  an  agent  to  take   appropriate   steps,  to  contact  the  remaining
Certificateholders  concerning  surrender  of their  Certificates,  and the cost
thereof  shall be paid out of the funds and other assets  which  remain  subject
hereto.  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.

                               GENERAL PROVISIONS

         Section  10.01.  Amendment.  This Agreement may be amended from time to
time  by  CMSI  and  the   Trustee,   without   the   consent   of  any  of  the
Certificateholders,  (a) to cure any ambiguity, (b) to correct or supplement any
provisions herein or therein which may be inconsistent with any other provisions
herein or therein,  (c) to add any other  provisions  with respect to matters or
questions arising under this Agreement. which shall not be inconsistent with the
provisions of this Agreement, (d) to comply with any requirements imposed by the
Code,  (e) to  establish a "qualified  reserve  fund" within the meaning of Code
Section  860G(a)(7)(B)  or (f) to  maintain  the status of the Trust Fund as two
separate  REMICs.  This  Agreement  may also be amended by CMSI and the Trustee,
without  Certificateholder  consent,  if CMSI  delivers  an  Opinion  of Counsel
acceptable to the Trustee to the effect that such  amendment will not materially
adversely  affect the interests of the  Certificateholders.  The Trustee  hereby
agrees to execute and deliver any amendment to this Agreement,  provided by CMSI
to it, that conforms to the applicable provisions of the preceding two sentences
of this  paragraph  provided,  however,  that the Trustee  may, but shall not be
obligated  to,  enter into any such  amendment  that affects the  Trustee's  own
rights, duties or immunities under this Agreement or otherwise.

         Except as otherwise  provided in Section 4.04,  this Agreement may also
be amended  from time to time by CMSI and the  Trustee  with the  consent of the
Holders of Certificates  evidencing,  in the aggregate, not less than 66-2/3% of
the  Voting  Interest  of each  Class  of  CitiCertificates  or the  Class  A-IO
Certificates  affected  by such  amendment  (after  giving  effect  to the first
proviso to the definition of "Outstanding" in Article I) and, if either Class of
the  Residual  Certificates  are  materially  and  adversely  affected  by  such
amendment,  66-2/3% of the  Percentage  Interests  of each of the Classes of the
Residual  Certificates so affected,  for the purpose of adding any provisions to
or  changing  in  any  manner  or  eliminating  any of the  provisions  of  this
Agreement,  or of  modifying  in any  manner  the  rights of the  Holders of the
Certificates;  provided,  however,  that no such  amendment  shall,  without the
consent of the Holders of all Certificates then  Outstanding,  (a) reduce in any
manner the amount of, or delay the timing of,  collections or payments  received
on  Mortgage  Loans  or  distributions  which  are  required  to be  made on any
Certificate  or (b) reduce the aforesaid  percentage  required to consent to any
such  amendment.  Promptly  after the execution of any such amendment or consent
the Trustee shall furnish or cause to be furnished  written  notification of the
substance of such amendment (or a copy thereof) to each Certificateholder.

         It shall not be necessary for the consent of  Certificateholders  under
this Section 10.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining  such consents and of evidencing  the  authorization  of the
execution thereof by the Certificateholders  shall be subject to such reasonable
requirements as the Trustee may prescribe.  Any proposed amendment is subject to
the receipt by the Trustee, at the expense of the party proposing such amendment
(or at the  expense  of the Trust  Fund if  proposed  by the  Trustee)  that the
amendment will not cause either the Upper-Tier  REMIC or the Lower-Tier REMIC to
fail to qualify as a REMIC or subject either REMIC to tax.

         Section 10.02.  Recordation of Agreement.  This Agreement is subject to
recordation in all appropriate  public offices for real property  records in all
the  counties  or other  comparable  jurisdictions  in  which  any or all of the
properties subject to the Mortgages are situated and in which this Agreement may
be recorded,  and in any other appropriate public recording office or elsewhere,
such  recordation  to be effected by CMSI and at its expense upon request of the
Trustee,  who  will  act at  the  direction  of the  Holders  of a  majority  by
Percentage Interest of the Residual  Certificates,  but only upon request of the
Trustee accompanied by an Opinion of Counsel to the effect that such recordation
materially  and  beneficially  affects the interests of the  Certificateholders;
provided, however, that CMSI shall not be required to effect recordation of this
Agreement unless, prior thereto, CMSI shall have become obligated to record each
assignment relating to the Mortgages pursuant to Section 2.01 hereto.

herein  provided  and  for  other  purposes,  this  Agreement  may  be  executed
simultaneously in any number of counterparts,  each of which  counterparts shall
be deemed to be an original,  and such counterparts shall constitute but one and
the same instrument.

         Section 10.03. Limitation on Rights of Certificateholders. The death or
incapacity  of  any  Certificateholder  shall  not  operate  to  terminate  this
Agreement  or  the  Trust  Fund,  nor  entitle  such  Certificateholder's  legal
representatives  or  heirs  to claim an  accounting  or to take  any  action  or
commence any  proceeding in any court for a partition or winding up of the Trust
Fund,  nor  otherwise  affect the rights,  obligations  and  liabilities  of the
parties hereto or any of them.

management of the Trust Fund or the obligations of the parties hereto, nor shall
anything  herein set forth,  or contained in the terms of the  Certificates,  be
construed  so as to  constitute  the  Certificateholders  from  time  to time as

Holders of Residual  Certificates)  or members of an association;  nor shall any
Certificateholder  be under any  liability  to any third person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

itself of any  provisions  of this  Agreement to institute  any suit,  action or
proceeding in equity or at law upon or under or with respect to this  Agreement,
unless such Holder  previously  shall have given to the Trustee a written notice
of default and of the continuance thereto as herein before provided,  and unless
also the Holders of the Required Amount of Certificates  shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee  hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require  against the costs,  expenses and  liabilities to be
incurred therein or thereby,  and the Trustee,  for 60 days after its receipt of
such notice, request and offer of indemnity,  shall have neglected or refused to
institute any such action, suit or proceeding; it being understood and intended,
and being  expressly  covenanted  by each  Certificateholder  with  every  other
Certificateholder  and the Trustee,  that no one or more Holders of Certificates
shall have any right in my manner  whatever by virtue or by  availing  itself or
themselves of any provisions of this  Agreement to affect,  disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain  priority over or  preference to any other such Holder,  or to enforce
any right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders.  For the protection
and  enforcement  of the  provisions  of this  Section  10.03,  each  and  every

given either at law or in equity.

provisions or terms of this Agreement and shall in no way affect the validity or
enforceability  of the other provisions of this Agreement or of the Certificates

         Section  10.09.  Certificates  Nonassessable  and Fully Paid. It is the
intention of the Trustee  that the  Certificateholders  shall not be  personally
liable for obligations of the Trust Fund, that the interests  represented by the

or for any reason  whatsoever,  and that the  Certificates  upon  authentication
thereof by the Trustee  pursuant to Section  2.05 are and shall be deemed  fully

                                   ARTICLE XI

         Section 11.01. Annual Statement as to Compliance.  CMSI will deliver to
the  Trustee  and  to  each  Holder  of  a  Certificate   holding   Certificates
representing  in excess of 50% of the Stated Amount or Percentage  Interest,  as
the case may be, on or before March 31 with respect to the  Affiliated  Mortgage
Loans and September 30 with respect to the CitiMae  Mortgage  Loans of each year
which begins not less than three  months after the date of the initial  issuance
of the Certificates,  an Officer's  Certificate stating that (a) a review of the
activities  of CMSI during the preceding  calendar  year and of its  performance
under this Agreement has been made under such officer's  supervision  and (b) to
the best of such officer's  knowledge,  based on such review, CMSI has fulfilled
all its obligations  under this Agreement  throughout such year, or if there has
been a default in the fulfillment of any such  obligation,  specifying each such
default  known to such officer and the nature and status  thereof and (c) in the
case of the CitiMae  Mortgage  Loans,  as to each Conduit  Servicer,  that (i) a
review of the activities of such Conduit Servicer during the preceding  calendar
year and  performance  under  the  Guide  has been  made  under  such  officer's
supervision,  and (ii) to the best of such  officer's  knowledge,  based on such

Escrow  Account,  Custodial  Accounts  for P&I or  Servicing  Account to a bank,
savings and loan  association or trust company  organized  under the laws of the
United  States  or any  State  thereof  (an  "eligible  depository").  Upon such
transfer,  such transferee  bank,  savings and loan association or trust company
shall be deemed to be a  Depository  with  respect to the account or accounts so
transferred.  In the event that the long-term debt obligations of any Depository
of the Certificate Account,  Buydown Account Escrow Account,  Custodial Accounts
for P&I or Servicing  Account shall be rated at less than A by Fitch if Fitch is
a Rating Agency,  or the short-term debt obligations of such Depository shall be
rated by S&P at less than A-1 if S&P is a Rating  Agency,  by Fitch at less than
F-1 if Fitch is a Rating  Agency and by Moody's at less than P-1 if Moody's is a
Rating Agency and such account does not otherwise meet the  requirements of this
Section 11.02, then within five Business Days of such reduction,  CMSI shall (A)

obligations  of which  are not  rated at less than A-1 by S&P if S&P is a Rating
Agency,  F-1 by Fitch if Fitch is a Rating  Agency and P-1 by Moody's if Moody's
is a Rating Agency (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",   the
"Alternative  Buydown  Account"   "Alternative  Escrow  Account",   "Alternative
Custodial Accounts for P&I" or the "Alternative  Servicing Account", as the case
may be) and  transfer  the funds from the  Buydown  Account  to the  Alternative
Buydown  Account  direct the Servicer or a Conduit  Servicer,  as  applicable to
remit in accordance  with this Agreement any funds  deposited into the Servicing

for P&I,  respectively,  and direct the Servicer or Master  Servicer to remit in
accordance with this Agreement 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,  Buydown  Account,  Escrow  Account,
Custodial Accounts for P&I or Servicing Account to the extent, if any, that such
obligation is not fully insured by the FDIC;  provided,  however,  that prior to
the day a Depository or CMSI, as the case may be, pledges securities pursuant to
this  subsection  (C),  CMSI and the  Trustee  shall have  received  the written
assurance  of each Rating  Agency 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 

                                       93

an  account  or  accounts  or  enter  into an  agreement  so that  the  existing
Certificate Account, Buydown Account, Escrow Account, Custodial Accounts for P&I
or  Servicing  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 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 that the  establishment
of such an  account  or the  entering  into of  such an  agreement  so that  the
existing Certificate Account,  Buydown Account or Servicing 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  (E)
establish another account which constitutes an Eligible Account or (F) make such
other  arrangements as to which CMSI and the Trustee have received prior written
assurance  from each Rating  Agency 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.
