          certificates of the class in proportion to the certificates’ principal or
          notional balances, except that an Insurer will be entitled to the voting
          interest of an insured class for as long as the insured class is outstanding

          Class balances

        Each
          class that is not an IO class will have a principal balance, and each
          IO class will have a notional balance. The principal or notional
          balance of multiple classes (e.g., the senior classes) is the aggregate
          of the principal or notional balances of those classes.

        The
          initial principal or notional balance for each class is stated in “The series –
General terms for classes” above. The principal balance of each class that is
          not an IO class will be adjusted on each

        The
          notional balance of a ratio-stripped IO class for any distribution day
          after the
          initial distribution day will equal the aggregate scheduled principal balance
          of
          the premium loans of the related pool on the last day of the preceding
          month.

        The
          notional balance of each IO class that is not a ratio-stripped IO class
          will be
          adjusted on each distribution day as described in “The series – General terms

          of each
          class will equal the initial principal or notional balance of the
          class.

        Except
          as
          may be provided in “Retail classes” below, the principal or notional balance of
          each certificate will equal its proportionate share, based on the initial
          principal or notional balances stated on the certificates of the class,
          of the
          principal balance or notional balance of the class to which the certificate
          belongs.

          Interest allocations

        Beginning
          on the cut-off date, each class (other than any PO class) will accrue interest
          for each month on its principal or notional balance at the certificate
          rate for
          the class stated in “The series – General terms for classes” above. In
          calculating accrued interest,

        ·      a
          class’s principal or notional balance on the last day of a month will be
          considered to be the class’s principal or notional balance on every day of the
          month, and

        ·      interest
          for a month will be calculated at 1/12 of the certificate rate, regardless
          of
          the number of days in the month.

        Example:
          Suppose that on January 1, a class has a principal balance of $1,020,000
          and a
          certificate rate of 6% per annum. On the January distribution day, the
          class’s
          principal balance is reduced by $20,000. As a result, the principal balance
          of
          the class on January 31 is $1 million. Then the interest accrued for the
          class
          during January (which is paid on the February distribution day) is 1/12
          of 6% of
          $1 million = $5,000; that the principal balance of the class was greater
          than $1
          million before the January distribution day, and that January has 31 days,
          are
          irrelevant.

        A
          class’s
interest allocation for a distribution day is the sum of

        ·      the
          class’s current interest allocation for the distribution day,
          consisting of the class’s accrued interest for the preceding month
minus the class’s proportionate share, based on accrued interest, of
          (1) any non-supported prepayment interest shortfall, and (2) the
          interest portion of any non-subordinated losses, for the preceding
          month,

        ·      plus
          any excess of the class’s interest allocation for the preceding
          distribution day over the interest distributed to the class on that preceding
          distribution day (the interest allocation carryforward from that
          distribution day). (If the class is an insured class, for purposes of
          calculating allocations and distributions to the class, the interest allocation
          carryforward from a distribution day will be reduced by any payments to
          the
          class from the Insurer relating to the interest allocation carryforward,
          but
          will not be so reduced for purposes of effecting the Insurer’s subrogation
          rights relative to the interest portion of any insured payment.)

          Principal allocations

        The

          day.

          Maintenance of subordination

        The
          subordination level for a class (other than a ratio-stripped IO class)
          is the sum of the class percentages of all classes that are subordinate
          to that
          class. If a class’s subordination level on the day before a distribution day is
          less than the class’s initial subordination level, then the class will have an
impaired subordination level on that distribution day.

        If
          a
          subordinated class has an impaired subordination level on a distribution
          day,
          then all principal originally allocated to the subordinated classes will
          be
          allocated to the most senior of the subordinated classes with an impaired
          subordination level and to those subordinated classes that are senior to
          the
          impaired class, in proportion to their principal balances, up to those
          classes’
principal balances, and any remainder will be allocated to the remaining
          subordinated classes, in order of seniority, up to those classes’ principal
          balances.

        Example:
          Suppose that on a distribution day, (a) each of classes B-1 through B-6 had
          a principal balance on the preceding day of $1,000, (b) the aggregate
          principal allocation to the subordinated classes is $3,120, and (c) class
          B-2 has an impaired subordination level. Then on that distribution
          day

        (1) the
          entire amount allocated to the subordinated classes will be allocated to
          classes
          B-1 and B-2, in proportion to their principal balances, up to their principal
          balances, and

        (2) $1,000
          of the remaining $1,120 will be allocated to class B-3, reducing its principal
          balance to zero, and

        (3)
          the remaining $120 will be allocated to class B-4.

          scheduled and unscheduled principal allocated to the senior target-rate

          of a group will be allocated to the individual senior target-rate classes
          of

        [ALLOCATION
          RULES]:

        Beginning
          on the subordination depletion date, the priorities stated above will cease
          to

          Distribution priorities

        Subject
          to section 18, “loss recoveries,” on each distribution day, the pool
          distribution amount will be first distributed to any Insurer to pay any
          insurance premium, and then to the outstanding classes in the following
          priority
          (and, if there are any insured classes, the insured payment and amounts
          withdrawn from the reserve fund will be applied to make payments to the
          insured
          class certificates as provided in “Insured classes” below):

        (1) To
          each senior class, first, its current interest allocation for that
          distribution day, and second its interest allocation carryforward from
          the preceding distribution day, except that an accrual class’s interest
          distributions may be redirected as described in “– Accrual and accrual directed
          classes” above. Distributions of current allocations among the senior classes
          will be in proportion to current interest allocations for, and distributions
          of
          interest allocation carryforwards will be in proportion to interest allocation
          carryforwards to, that distribution day.

        (2) (a) To
          any ratio-stripped PO class, principal up to its principal allocation for
          that
          distribution day, and (b) to the senior target-rate classes, principal up
          to their aggregate principal allocation for that distribution day, to be
          distributed to the senior target-rate classes in the priorities described
          in
“Allocations among the senior classes – Order of allocation among senior
          target-rate classes” above.

        (3) To
          each subordinated class, in order of seniority, first, interest up to
          its interest allocation for that distribution day, and second,
          principal up to its principal allocation for that distribution day,
          except that a subordinated class’s principal distribution may be used to
          reimburse a ratio-stripped PO class, as described in the following
          paragraph.

        (4) Principal
          distributed to the subordinated classes under the preceding paragraph will
          be
          used to reimburse a ratio-stripped PO class up to the amount of (a) any
          realized subordinated losses previously allocated to the ratio-stripped
          PO
          class, and (b) any reduction to the ratio-stripped PO class’s principal
          balance to reflect the excess of (i) the aggregate principal allocations to
          the ratio-stripped PO class over (ii) the aggregate principal distributions
          to the ratio-stripped classes, as described in “Adjustments to class balances”
below, to the extent that such losses and reductions were not previously
          reimbursed under this paragraph (4) or “Loss recoveries” below. Such
          reimbursements will be taken from distributions to the subordinated classes
          in
          order of subordination.

          the
          classes’ principal balances to reflect the excess of (a) the aggregate
          principal allocations to the classes over (b) the aggregate principal
          distributions to the classes, as described in “Adjustments to class balances”
below, to the extent such reductions were not previously reimbursed. Classes
          with equal seniority will share in the reimbursement in proportion to such
          unreimbursed reductions.

        (6) To
          the residual certificates, a residual distribution of the remaining pool
          distribution amount.

        A
          class
          that is no longer outstanding cannot receive a distribution.

        Notwithstanding
          anything to the contrary in this agreement, no distribution will be made
          to a
          subordinated class on a distribution day if on that distribution day the

        On
          each
          distribution day, the principal balance of each class that is not an IO
          class
          will be adjusted, in the following order, as follows:

        (1) The
          principal balance of any ratio-stripped PO class will be reduced by realized
          losses on its PO strip for the preceding month.

        (2) The
          aggregate principal balance of the target-rate classes will be reduced
          by the
          principal portion of realized non-subordinated losses on the target-rate
          strip
          for the preceding month. The reduction will first be allocated between
          the
          subordinated classes, collectively, and the senior target-rate classes,
          collectively, in proportion to aggregate principal balances. The reduction
          for
          the subordinated classes will be allocated to the individual subordinated
          classes in proportion to their principal balances. The reduction for the
          senior
          target-rate classes will be allocated to the individual senior target-rate
          classes in proportion to their principal balances, except that the
          principal balance of an accrual class will be deemed to be the lesser of
          its
          principal balance or its initial principal balance.

        (3) To
          the extent that on the distribution day an interest distribution to an
          accrual
          class is redirected to an accrual directed

        class,
          the principal balance of the accrual class will be increased.

        (4) The
          principal balance of each class will be reduced by its principal distributions
          for that distribution day, including

        
          	
                   

                	
                  (a) principal
                    distributions to an accrual directed class that are redirected
                    from
                    interest distributions to an accrual class,
                    and

                

        

        
          	
                   

                	
                  (b) principal
                    distributions to a subordinated class, even if part or all of
                    those
                    principal distributions are, pursuant to section 16.3(4), used
                    to
                    reimburse a ratio-stripped PO
                    class.

                

        

        However,
          any portion of an accrual class’s interest distribution that, on the
          distribution day before the class’s accrual termination day, is distributed as
          principal to the accrual class itself, will neither increase nor decrease
          the
          class’s principal balance.

        (5) The
          aggregate principal balance of the target-rate classes will be reduced
          by the
          principal portion of realized subordinated losses on the target-rate strip
          for
          the preceding month. The reductions will be applied first to the subordinated
          classes in order of subordination, in each case until the principal balance
          of
          the class is reduced to zero. If the realized subordinated losses exceed
          the
          principal balance of the subordinated classes, the principal balance of
          the
          senior target-rate classes will be reduced by the amount of the excess.
          The
          excess will be allocated among the senior target-rate classes in proportion
          to
          their principal balances, except that for this allocation, the
          principal balance of an accrual class will be deemed to be the lesser of
          its
          principal balance or its initial principal balance.

        (6) The
          principal balance of any ratio-stripped PO class will be reduced by the
          excess
          of (a) the class’s principal allocation over (b) the class’s principal
          distribution for that distribution day.

        (7) The
          principal balance of each target-rate class will be reduced, in order of
          subordination, in an aggregate amount equal to the excess of (a) the
          aggregate principal allocations to the target-rate classes over (b) the
          aggregate principal distributions to the target-rate classes. Classes of
          equal
          seniority will share in such reduction in proportion to the amounts by
          which the
          principal allocation to each such class exceeded its principal
          distribution.

        For
          purposes of the preceding paragraphs (1) through (7),

        ·      the
          principal portion of a debt service reduction will not be considered a
          realized
          loss, and

          to the class principal balances in any paragraph mean the principal balances
          after the adjustments required by the preceding numbered
          paragraphs.

        Where
          the
          principal balance of a class is reduced due to a realized loss under the
          preceding paragraphs (1), (2) or (5), the loss will be said to be allocated
          to
          the class (an allocated loss) to the extent of the
          reduction.

        The
          following rules for loss recoveries supersede any conflicting rules in
          “Distributions” or “Adjustments to class balances” above.

        On
          each
          distribution day, the amount of any loss recovery for the preceding month
          will
          be distributed as follows:

        First,
          to each senior class to the extent of and in proportion to its aggregate
          realized losses for that and all preceding months that were not previously
          reimbursed under this paragraph or, for a ratio-stripped PO class, paragraph
          4
          of “Distributions — Distribution priorities” above.

        
          
             

          

          
            19

            
              

            

          

          
             

          

        

        Second,
          to the target-rate classes in the same manner as a distribution of unscheduled
          principal.

        Distributions
          made pursuant to paragraph First above will not result in any
          adjustments to class balances, but distributions made pursuant to paragraph
          Second above will result in the normal adjustments to the class
          balances described in paragraph 4 of “Adjustments to class balances”
above.

        The
          principal balances of the subordinated classes will be increased in order
          of
          seniority to the extent of their aggregate realized losses for that and
          all
          preceding months that were not previously reimbursed under this paragraph,
          up to
          an aggregate amount for all subordinated classes equal to the loss recovery
          less
          the amounts distributed to the senior classes under paragraph First
          above.

        Example:
          In May, there is a $1,000 loss recovery. On the June distribution day,
          prior to
          any distributions or adjustments, the senior classes have aggregate unreimbursed
          losses of $100 of losses that were not subject to subordination and the
          subordinated classes have aggregate unreimbursed losses of $700. (Unreimbursed
          losses can be less than the recovery if some classes that previously absorbed
          losses are no longer outstanding.) Then on the June distribution
          day,

        1        $100
          of the loss recovery will be distributed to the senior classes to reimburse
          them
          for previously allocated losses, but the distribution will not reduce the
          principal balances of the senior classes.

        2        The
          remaining $900 of the loss recovery will be distributed to the target-rate
          classes in the same manner as unscheduled principal, and class balances
          will be
          reduced by the amount of the distributions.

        3        The
          principal balances of the subordinated classes will be increased by $700,
          in
          order of seniority up to the amount of unreimbursed losses.

        If
          expenses on the liquidated loans for any month exceed the amounts recovered
          on
          the liquidated loans for the month, the excess will be treated as a realized
          loss on the mortgage loans.

        The

          to
          class balances, are subject to the following sections on LIBOR classes,

          are no LIBOR classes.}

        [Classes
          IA-5 and IA-6 are LIBOR classes.

        Each
          LIBOR class will have a monthly LIBOR accrual period from the
          day of the month indicated in the footnotes to the table in “The Series –
General terms for classes” above through the day preceding the first day of the
          next LIBOR accrual period. The first LIBOR accrual period for a class will
          be
          the latest possible LIBOR accrual period that ends before the first distribution
          day.

        Example:
          The LIBOR accrual period for a LIBOR class begins on the 25th day of the
          month,
          and the first distribution day is February 25, 200x. Then the first LIBOR
          accrual period for the class begins on January 25, 200x and runs through
          February 24, 200x, the second LIBOR accrual period begins on February 25,
          200x
          and runs through March 24, 200x, and so forth.

        A
          LIBOR
          class will not accrue interest for any period before its first LIBOR accrual
          period. The interest rate for each LIBOR class is stated in “The series –

        The
          composite classes of the series, and each composite class’s
component classes are shown in the table in “The series – General terms
          for classes” above.

        Each
          composite class is comprised of two or more component classes. Certificates
          are
          only issued for composite classes. Component classes cannot be severed
          from
          their composite classes, and cannot be separately transferred. Component
          classes
          are, however, considered classes for all purposes of the preceding sections
          on
          allocations and distributions except that all distributions to the
          component classes of a composite class will become distributions to the
          composite class. A composite class is not considered a class for purposes
          of
          allocations and distributions, but instead receives all the distributions
          made
          to any of its component classes. Voting is by composite, not component,
          classes.

        In
          a
          multiple-pool series, each subordinated class is a composite class formed
          of two
          or more component classes. Unless otherwise specified, references to a
          “subordinated class” mean the composite class.

          not a multiple pool series.]

        [This
          is
          a multiple-pool series. The mortgage loans of this series are divided into
          three
          pools. Pool I consists of the mortgage loans described in exhibit B-1,
Pool II consists of the mortgage loans described in exhibit
          B-2,
          [and Pool III

        consists
          of the mortgage loans described in exhibit B-3].

        Each
          class of this series (other than certain composite classes) belongs to
          a
group of classes related to a specific pool. The designation of each
          class in a group bears the roman numeral prefix of its related pool, and
          the
          group is referred to by that prefix.

        Example:
          Classes related to pool I bear the prefix “I,” as IA-1, IB-1, etc., and are
          referred to collectively as “group I.”

        With
          exceptions described below, the classes of each group are treated like
          a
          separate series, with allocations to the classes of the group being based
          solely
          on payments on the related pool. Any ratio-stripping will be done on a
          pool
          basis, so that there will be separate PO, IO and target-rate strips for
          each
          pool, with the related group having its own target-rate, and ratio-stripped
          IO
          and PO, classes.

        The
          subordinated classes of each group will be component classes. A ratio-stripped
          IO or PO class of a group will only be a component class if so designated
          in
“The series – General terms for classes” above.]

          Adjustment of subordinated component class principal
          balances

        On
          each
          distribution day, the aggregate amount of any

        ·      realized
          subordinated losses on the mortgage loans in a pool, or

        ·      excess
          of the aggregate principal allocations to the related group’s target-rate
          classes over the aggregate principal distributions to those
          classes,

        that,
          in
          accordance with “Adjustments to class balances” above, would reduce the
          principal balances of the group’s subordinated component classes in order of
          subordination if the pool and the related groups were considered a separate
          series, will instead reduce

        ·      the
          principal balances of the subordinated composite classes in order of
          subordination, and

        ·      the
          aggregate principal balance of the group’s subordinated component
          classes,

        by
          that
          amount.

        Such
          reduction in the aggregate principal balance of a group’s subordinated component
          classes will result in adjustments to the principal balance of the subordinated
          component classes of each group so the ratio of the principal balances
          of the
          component classes from each group will be the same for each subordinated
          composite class.

        Example:
          Assume subordinated composite classes B-1 through B-6, each with a principal
          balance of $1,000. There are two groups, I and II, and the aggregate principal
          balance of each group’s subordinated component classes is $3,000. Then for each
          subordinated composite class, the ratio of the principal balance of its
          group I
          component class to the principal balance of its group II component class
          must be
          1 to 1. Consequently, both the group I and the group II component class
          of each
          subordinated composite class will have a principal balance of
          $500.

        Now
          assume a $750 subordinated loss in pool I. Then

        ·      the
          principal balance of class B-6 will be reduced by $750, to $250, which
          will
          reduce the aggregate principal balance of the subordinated composite classes
          to
          $5,250,

        ·      the
          aggregate principal balance of the group I subordinated component classes
          will
          be reduced by $750, to $2,250, while the aggregate principal balance of
          the
          group II subordinated component classes will remain at $3,000;

        ·      the
          ratio of the aggregate principal balance of the group I subordinated component
          classes to the aggregate principal balance of the group II subordinated
          component classes will be $2,250 to $3,000, or 3 to 4;

        
          
             

          

          
            22

            
              

            

          

          
             

          

        

        ·      for
          classes B-1 through B-5, the principal balance of the composite class will
          remain at $1,000, but the principal balance of its group I component class
          will
          be approximately $428.57, and the principal balance of its group II component
          class will be approximately $571.43 (a ratio of 3 to 4); and

        ·      class
          B-6’s principal balance of $250 will be comprised of a group I component class
          with a principal balance of approximately $107.14, and a group II component
          class with a principal balance of approximately $142.86 (a ratio of 3 to
          4).

        If
          subordinated losses on a mortgage pool for a distribution day exceed the
          aggregate principal balance of the subordinated component classes of the
          related
          group, the aggregate principal balance of such component classes will be
          reduced
          to zero, and the aggregate principal balance of the subordinated component
          classes of the other groups will be reduced by the excess.

        Example:
          Suppose that in the series in the preceding example, the group I subordinated
          component classes and the group II subordinated component classes each
          have an
          aggregate initial principal balance of $3,000, and that each subordinated
          composite class, B-1 through B-6 has a principal balance of $1,000. Now
          suppose
          that there are $4,000 of subordinated losses on the mortgage loans in pool
          II’s
          target-rate strip, but no losses on the mortgage loans in pool I’s target-rate
          strip. Then the entire $4,000 of losses will be allocated to the subordinated
          classes, reducing the principal balance of classes B-3 through B-6 to zero.
          Classes B-1 and B-2 will each retain a principal balance of $1,000, comprised
          of
          a group I component class with a principal balance of $1,000 and a group II
          component class with a principal balance of $0. The principal balance of
          the
          subordinated group I component classes will thus be reduced by $1,000 even
          though there are no losses on the pool I target-rate strip.

        Subject
          to “– Undercollateralization” below, if realized subordinated losses on a
          distribution day exceed the aggregate principal balance of the subordinated
          classes, the aggregate principal balance of the senior classes in each
          group
          will be reduced by the group’s proportionate share of the excess losses, based
          on the proportions of all the losses for that distribution day in the mortgage
          loan pools.

        Example:
          Assume that for a distribution day, there are $2,250 of realized subordinated
          losses in pool I and $4,500 of realized subordinated losses in pool II.
          The
          aggregate principal balance of the subordinated classes is only $6,000.
          Then the
          principal balance of the subordinated classes will be reduced to $0, and
          the
          remaining $750 of losses will reduce the aggregate principal balance of
          the
          senior classes of group I by $250 (or 1/3 of $750), and will reduce the
          aggregate principal balance of the senior classes of group II by $500 (or
          2/3 of
          $750). The principal balances of the component classes of the subordinated
          classes are irrelevant for these purposes.

         

        22.2
          Maintenance of subordination

        Impairment
          of subordination for subordinated classes of a multiple-pool series will
          be
          determined based on composite, not component, classes. In determining whether
          a
          composite class has an impaired subordination level, the principal balance
          of
          the composite class will equal the sum of the principal balances of its
          component classes. If a subordinated composite class has an impaired
          subordination level, then principal will be allocated among the subordinated
          composite classes pursuant to “Allocations – Maintenance of subordination”
above, and, for purposes of adjusting principal balances, will be further
          allocated to the component classes in proportion to their principal
          balances.

        22.3
          Distribution shortfalls

        If
          on a
          distribution day, payments on the mortgage loans in the target-rate strip
          for a
          pool are not sufficient to permit payments of any insurance premium due
          to an
          Insurer, and all interest and principal allocated to the senior target-rate
          classes of the related group, then the pool may receive insurance premium,
          interest and principal distributions from payments on the mortgage loans
          in
          another pool once any insurance premium due is paid to the Insurer, and
          full
          interest and principal distributions are made to the senior target-rate
          classes
          of the group related to the other pool.

        Example:
          Suppose that there are two groups of classes and that on a distribution
          day,
          cash available for distribution to the group I senior-target rate classes
          from
          payments on the pool I mortgage loans is $1,000 less than the aggregate
          interest
          and principal allocations to group I’s senior target-rate classes, while cash
          available for distribution to the group II senior-target rate classes from
          payments on the pool II mortgage loans exceeds the aggregate interest and
          principal allocations to group II’s senior target-rate classes by $1,500. Then
          $1,000 of the extra $1,500 available to group II will be used to make full
          interest and principal distributions to the group I senior target-rate
          classes,
          and only the remaining $500 will be distributed to the group II subordinated
          component classes.

        If
          there
          are several pools for which mortgage loan payments do not provide enough
          cash
          for full distributions to the senior target-rate classes and any Insurer,
          the
          related groups will receive cash from other pools in proportion to the
          aggregate
          amount by which any insurance premium due to an Insurer, and interest and
          principal distributions would otherwise fall short of interest and principal
          allocations. If there are several pools where mortgage loan payments provide
          cash in excess of the amount required for full distributions, they will
          provide
          cash to the senior target-rate classes, and any Insurer, of those groups
          related
          to the other pools in proportion to the amounts of the excess.

         

        22.4
          Undersubordination

        If
          on a
          distribution day before the subordination depletion date, the principal
          balances
          of all the senior target-rate classes of any group (but not the principal
          balances of all the group’s subordinated component classes) have been reduced to
          zero, and there is undersubordination (as defined below), then on that
          distribution day, before any distributions are made,

        ·      the
          pool distribution amount of the group will be reduced by an amount (the
          reduction amount) equal to the lesser of (1) unscheduled principal
          payments on the related pool’s target-rate strip received by the Trust during
          the preceding month and (2) the excess, determined without regard to this
          section “– Undersubordination,” of the pool distribution amount over the amount
          required to be used to reimburse any ratio-stripped PO classes,

        ·      the
          principal allocation to each class in the group will be reduced by the
          class’s
          proportionate share, based on principal balances, of the reduction
          amount,

        ·      the
          pool distribution amount of each group whose senior target-rate classes
          have not
          been reduced to zero will be increased by a proportionate share of the
          reduction
          amount based on the aggregate principal balance of the senior target-rate
          classes of each such group, and

        ·      the
          aggregate principal allocation for the senior target-rate classes of each
          group
          whose senior target-rate classes have not been reduced to zero will be
          increased
          by the portion of the reduction amount added to its pool distribution amount,
          which

        
          
             

          

          
            24

            
              

            

          

          
             

          

        

        increased
          aggregate allocation will be further allocated among the senior target-rate
          classes in accordance with the rules in “Allocations among the senior
          target-rate classes” above.

        There
          is
undersubordination on a distribution day if either

        ·      the
          subordination level of the senior classes (without regard to group) on
          that
          distribution day is less than 200% of the initial subordination level of
          the
          senior classes, or

        ·      the
          aggregate scheduled principal balance of the mortgage loans in any pool
          that are
          delinquent 60 days or more (including for this purpose mortgage loans in
          foreclosure and real estate owned by the Trust as a result of Mortgagor
          default), averaged over the last six months, is 50% or more of the principal
          balance of the related group’s subordinated component classes.

         

        22.5
          Undercollateralization

        Because
          losses on a mortgage loan may be allocated in part to the subordinated
          component
          classes of a different group, the scheduled principal balance of a pool’s
          target-rate strip could differ from the aggregate principal balance of
          the
          related group’s target-rate classes. If the scheduled principal balance of a
          pool’s target-rate strip is less than the aggregate principal balance of the
          related group’s target-rate classes, the group will be
undercollateralized by the amount of the difference; conversely, if the
          scheduled principal balance of a pool’s target-rate strip is more than the
          aggregate principal balance of the related group’s target-rate classes, the
          group will be overcollateralized by the amount of the
          difference.

        If
          a
          group is undercollateralized, the normal distribution rules will be adjusted
          as
          follows:

        (1) To
          the extent that scheduled interest payments on the target-rate strip of
          a pool
          related to an overcollateralized group exceed the aggregate interest allocations
          to that groups’ target-rate classes, plus any insurance premium due to an
          Insurer, that excess, up to the amount of any interest allocation carryforwards
          that the undercollateralized group would otherwise experience on that
          distribution day and the insurance premium, will be deducted from the pool
          distribution amount for the overcollateralized group and added to the pool
          distribution amounts for the undercollateralized group. If there is more
          than
          one such undercollateralized group, or more than one overcollateralized
          group,
          then (a) amounts will be deducted from the pool distribution amounts for
          the groups that are overcollateralized in proportion to such excess interest
          payments, up to the aggregate amount of such interest allocation carryforwards
          and the insurance premium for the undercollateralized groups, and
          (b) amounts will be added to the pool distribution amounts of the
          undercollateralized groups in proportion to the amount of such interest
          allocation carryforwards and insurance premium.

        (2) Before
          the subordination depletion date, if one or more groups is undercollateralized
          and the principal balance of each of the groups’ subordinated component classes
          has been reduced to zero, then (a) all amounts that (after required
          reimbursements to any ratio-stripped PO classes) would otherwise be distributed
          as principal to the subordinated component classes of the other groups,
          up to
          the aggregate amount by which such undercollateralized groups are
          undercollateralized, will, in proportion to the aggregate principal balance
          of
          the subordinated component classes of such

        
          
             

          

          
            25

            
              

            

          

          
             

          

        

        other
          groups, be deducted from the pool distribution amount and the principal
          allocations to the subordinated component classes of such other groups,
          and
          (b) such amount will be added to the pool distribution amounts and the
          principal allocations of the target-rate classes of such undercollateralized
          groups, in proportion to the amount by which such groups are
          undercollateralized.

        (3) After
          the subordination depletion date, if a group is undercollateralized,
          then

        ·      once
          a group’s target-rate classes are all reduced to zero, principal payments on the
          related pool’s target-rate strip will be added to the pool distribution amount
          and to the principal allocations of the target-rate classes of the
          undercollateralized groups, in proportion to the amount by which they are
          undercollateralized, and

        ·      realized
          losses on the target-rate strips of the pools related to the overcollateralized
          groups will, up to the amount by which the group is overcollateralized,
          not
          reduce the principal balances of the target-rate classes of those groups,
          but
          will instead reduce the principal balances of the target-rate classes of
          the
          undercollateralized groups, in proportion to the amount by which they are
          undercollateralized, and in accordance with “Adjustments to class balances”
above. If there is more than one overcollateralized group, the losses that
          will
          not reduce principal balance will be in proportion to the amount by which
          each
          group is overcollateralized. If there is more than one undercollateralized
          group, the aggregate reductions in principal balances for each group will
          be in
          proportion to the amounts by which such groups are
          undercollateralized.

         

        22.6
          Non-subordinated interest shortfalls

        Prior
          to
          the subordination depletion date, reductions to interest allocations due
          to
          (a) interest shortfalls due to the federal Servicemembers Civil Relief Act
          or any comparable state laws and (b) non-supported prepayment interest
          shortfalls will be allocated pro-rata to all the classes of all the groups,
          regardless of the pools in which the shortfalls originate.

        From
          and
          after the subordination depletion date,

        ·      interest
          shortfalls due to the federal Servicemembers Civil Relief Act or any comparable
          state laws will be separately calculated for each pool, and will be allocated
          solely to the classes of the related group, and

        ·      the
          compensating cap and non-supported prepayment interest shortfalls will
          be
          separately calculated for each pool, and non-supported prepayment interest
          shortfalls for a pool will be allocated solely to the classes of the related
          group.

        The
          Trustee acknowledges that it is holding the class P regular interests as
          assets
          of the lower-tier REMIC and any class L regular interests as assets of
          the
          upper-tier REMIC.

         

        27.3
          Principal distributions and loss allocations to class L and class P regular
          interests

        On
          each
          distribution day, the class LI-[**] regular interest will receive a principal
          distribution, or allocation of the principal portion of realized losses,
          equal
          in the aggregate to the principal distribution, or allocation of the principal
          portion of realized losses, for that day, on class [***].

        For
          each
          distribution day, and for each pool x and y, a
          Px-M regular interest will receive distributions of principal,
          or allocation of the principal portion of realized losses on the related
          target-rate strip, so as to keep its principal balance (computed to $.000001)
          equal to 0.01% of the aggregate principal balance of the subordinated component
          classes of the related group. However, if the ratio of the principal balance
          of
          a Px-M regular interest to the principal balance of a Py-M
          regular interest is not the same as the ratio of the aggregate principal
          balance
          of the component classes xB-1 through xB-6 to the aggregate
          principal balance of the component classes yB-1 through yB-6,
          then the least amount of principal will be distributed to the Px-M or
          Py-M regular interest, as applicable, so that the ratio of the
          principal balance of the Px-M regular interest to the principal balance
          of the Py-M regular interest will be the same as the ratio of the
          aggregate principal balance of the component classes xB-1 through
xB-6 to the aggregate principal balance of the component
          classes
yB-1 through yB-6. Also, for such distribution day, the Px-Q
          regular interest will receive the balance of the principal distribution,
          and
          allocation of the principal portion of realized losses on its related
          target-rate strip.

        Recoveries
          of previously allocated realized losses of principal will be allocated
          to any
          class P and class L regular interests in the same manner as realized losses
          were
          allocated to them.

         

        27.4
          Interest distributions to class L and class P regular
          interests

        On
          each
          distribution day, each class P or class L regular interest will receive
          an
          interest distribution at its certificate rate,

        
          
             

          

          
            28

            
              

            

          

          
             

          

        

        and
          interest shortfalls and the interest portion of realized losses for the
          related
          target-rate strip will be allocated to such regular interest in the same
          proportion as interest is allocated to them, provided that

        ·      (a) prior
          to the subordination depletion date, non-supported prepayment interest
          shortfalls will be allocated pro-rata to all the class P regular interests,
          regardless of the pool in which the shortfalls originate, and (b) from and
          after the subordination depletion date, non-supported prepayment interest
          shortfalls for any pool x (where x is a variable for pool
          designations I, II, etc.) will be allocated solely to the Px-M
          and Px-Q regular interests, and

        ·      (a) prior
          to the subordination depletion date, any class L regular interest will
          be
          allocated its proportional share, based on accrued interest of any lower-tier
          REMIC regular interests, of non-supported prepayment interest shortfalls,
          regardless of the pool in which the shortfalls originate, and (b) from and
          after the subordination depletion date, any class L regular interest will
          be
          allocated its proportional share, based on accrued interest of any class
          L
          regular interests and the other lower-tier REMIC regular interests designated
          class xA, of non-supported prepayment interest shortfalls for pool
x.

        No
          interest shortfall amount or unpaid interest shortfall on any class P or
          class L
          regular interest will bear interest.

         

        27.5
          REMIC accounts and distributions

        (a)
          CitiMortgage, the Trustee and the Paying Agent will

        ·      perform
          their duties in a manner consistent with the REMIC provisions of the Internal
          Revenue Code, and will not knowingly take or fail to take any action that
          would
          adversely affect the continuing treatment of the Trust Fund as segregated
          asset
          pools and the treatment of each such segregated asset pool as a REMIC or
          would
          result in the imposition of a tax on the Trust Fund, or any constituent
          REMIC,
          and

        ·      carry
          out their covenants in this agreement and the elections and reporting required
          in section 3.15 on behalf of each constituent REMIC, including maintaining
          the
          following segregated accounts:

        ·        the
          certificate account,

        ·        if
          there is a pooling REMIC, a pooling REMIC account,

        ·        a
          lower–tier REMIC account, and

        ·        if
          there is an upper-tier REMIC, an upper-tier REMIC
          account.

        Any
          pooling REMIC account, the lower-tier REMIC account, and any upper-tier
          REMIC
          account will be established in the same manner as the certificate
          account.

        CitiMortgage,
          on behalf of the Trustee, will deposit daily in the certificate account
          in
          accordance with section 3.3 all remittances received by it, any amounts
          required
          to be deposited in the certificate account pursuant to section 3.2, all
          other
          deposits required to be made to the certificate account other than those
          amounts
          specifically designated to be deposited in any pooling REMIC account, the
          lower-tier REMIC account, or any upper-tier REMIC account in this section,
          “REMIC accounts and distributions,” 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 will be
          held
          and invested in accordance with the applicable provisions of section 3.2
          and
          3.20. Distributions from the certificate account will be made in accordance
          with
          sections 3.6, 3.8 and these Series Terms to make payments in respect of
          the
          regular and residual interests in any pooling REMIC, the lower-tier REMIC,
          and
          any upper-tier REMIC and to pay servicing fees in

        accordance
          with section 3.6(h) and any insurance premium.

        Notwithstanding
          anything herein to the contrary, regular and residual interests in any
          pooling
          REMIC, the lower-tier REMIC, and any upper-tier REMIC will not receive
          distributions directly from the certificate account. On each distribution
          day,

        ·      if
          there is a pooling REMIC, CitiMortgage, on behalf of the Trustee, will
          withdraw
          from the certificate account and deposit by 12 noon in the pooling REMIC
          account
          all distributions to be made on such distribution day in respect of interest
          on
          or in reduction of the principal balance of any class P regular interests,
          and

        ·      if
          there is no pooling REMIC, CitiMortgage, on behalf of the Trustee, will
          withdraw
          from the certificate account and deposit by 12 noon in the lower-tier REMIC
          account all distributions to be made on such distribution day in respect
          of
          interest on or in reduction of the principal balance of the regular interests
          in
          the lower-tier REMIC.

        If
          there
          is an upper-tier REMIC, CitiMortgage, on behalf of the Trustee, will immediately
          thereafter withdraw from the lower-tier REMIC account and deposit in the
          upper-tier REMIC account all distributions to be made on such distribution
          day
          in respect of interest on or in reduction of the principal balance of any
          class
          L regular interests.

        The
          Trustee will cause to be distributed from the lower-tier REMIC account
          and any
          upper-tier REMIC account, to the extent funds are on deposit therefor,
          all
          amounts required to be distributed with respect to the regular and residual
          interests in the lower-tier REMIC and any upper-tier REMIC as specified
          in these
          Series Terms.

        To
          the
          extent that any part of the lower-tier REMIC account or any upper-tier
          REMIC
          account is designated in these Series Terms as an investment account, the
          provisions in section 3.19 applicable to the investment of funds will apply
          to
          such REMIC accounts. In addition, section 3.3(a) regarding commingling
          will
          apply to such REMIC accounts.

        (b) CitiMortgage
          will maintain books for constituent REMICs on a calendar year taxable year
          and
          on the accrual method of accounting.

        (c) The
          Trustee will not create, or permit the creation of, any “interests” in any
          constituent REMIC within the meaning of Internal Revenue Code Section 860D(a)(2)
          other than the interests represented by the certificates or, if there are
          multiple REMICs, the uncertificated regular interests in any pooling REMIC
          or
          (if there is an upper-tier REMIC) the lower-tier REMIC.

        (d) Except
          as otherwise provided in the Internal Revenue Code, CitiMortgage will not
          grant,
          and neither CitiMortgage nor the Trustee will accept, property unless
          (i) substantially all of the property held by each constituent REMIC
          constitutes either “qualified mortgages” or “permitted investments” as defined
          in Internal Revenue Code Sections 860G(a)(3) and (5), respectively, and
          (ii) no property will be granted to a constituent REMIC after the startup
          day, unless the grant would not subject the constituent REMIC to the 100%
          tax on
          contributions to a REMIC after the startup day imposed by Internal Revenue
          Code
          Section 860G(d).

        (e)
          The
          Trustee will not accept on behalf of the Trust Fund or a constituent REMIC
          any
          fee or other compensation for services and will not accept on behalf of
          the
          Trust Fund any income from assets other than those permitted to be held
          by a
          REMIC.

        (f) Neither
          CitiMortgage nor the Trustee will sell or permit the sale of all or any
          portion
          of the mortgage loans, or of an

        Eligible
          Investment held in the certificate account or in any REMIC account (other
          than
          in accordance with sections 2.2, 2.3, 2.4 and 3.19(a)) unless such sale
          is
          pursuant to a “qualified liquidation” as defined in Internal Revenue Code
          Section 860F(a)(4)(A) and is in accordance with section 9.1.

         

        27.6
          Tax matters person

        If
          in any
          taxable year there will be more than one holder of any class of residual
          certificates, a tax matters person may be designated for the related
          REMIC, who will have the same duties for the related REMIC as those of
          a “tax
          matters partner” under Subchapter C of Chapter 63 of Subtitle F of the Internal
          Revenue Code, and who will be, in order of priority, (i) CitiMortgage or an
          affiliate of CitiMortgage, if CitiMortgage or such affiliate is the holder
          of a
          residual certificate of the related REMIC at any time during the taxable
          year or
          at the time the designation is made, (ii) if CitiMortgage is not a holder
          of a residual certificate of the related REMIC at the relevant time,
          CitiMortgage as agent for the holder of the residual certificate of the
          related
          REMIC, if the designation is permitted to be made under the Internal Revenue
          Code, or (iii) the holder of a residual certificate of the related REMIC or
          person who may be designated a tax matters person in the same manner in

        28.1
          Yield maintenance agreement

        [There
          are no classes of yield protected certificates.]

        [Class
          [***] is a class of yield protected certificates.

        The
          Trustee is hereby directed to enter into one or more yield maintenance
          agreements (together, the yield maintenance agreement) with [***] (the
yield maintenance provider) in substantially the form attached as
          exhibit F. The yield maintenance agreement is an asset of the Trust, but
          not of
          any constituent REMIC.

        Payments
          to the yield maintenance provider will be made by [underwriter], and the
          Trustee
          will have no responsibility for such payments.

        Under
          the
          yield maintenance agreement, the yield maintenance provider will make yield
          maintenance payments for the benefit of the holders of the yield protected
          certificates.

        Each
          yield maintenance payment for a class of yield protected certificates will
          be a
          per annum percentage (the yieldmaintenance percentage) of an
assumed principal balance for the class for the relevant distribution
          day. The yield maintenance percentage will equal the excess of LIBOR for
          that
          distribution day over the maximum LIBOR shown
          below for the class, up to the maximum protection percentage shown for
          that class.

         

        
          	
                  Class

                	
                  Maximum
                    LIBOR

                	
                  Maximum
                    protection percentage

                
	
                  [***]

                	
                  [***]%

                	
                  [***]%

                

        

         

        Where
          the
          annual rate for a class of certificates is specified as LIBOR plus a
          percentage margin, subject to a maximum rate, the maximum LIBOR will be
          the excess of the maximum rate over the margin.

        Example:
          Suppose the annual interest rate formula for a class of yield protected
          certificates is LIBOR + 0.5%, subject to a maximum rate of 6%. Then 0.5%
          is the
          margin, and the

        
          
             

          

          
            31

            
              

            

          

          
             

          

        

        maximum
          LIBOR is 5.5% (the 6% maximum rate minus the 0.5% margin). In the absence
          of a
          yield maintenance agreement, even if LIBOR is over 5.5% for a distribution
          day,
          certificate holders can not receive interest at an annual rate of more
          than
          6%.

        Now
          suppose that for a distribution day, LIBOR is 6.3% and the actual principal
          balance of the class is $2 million, and that under a yield maintenance
          agreement
          for the class, the maximum protection percentage is 3%, and the assumed
          principal balance for the distribution day is $1.6 million. Accordingly,
          the
          class will receive a yield maintenance payment equal to one-twelfth of
          0.8% (the
          excess of 6.3% over the maximum LIBOR of 5.5%) of $1.6 million (the assumed
          principal balance), or approximately $1,067.

        What
          if LIBOR had been 9% rather than 6.3%? The excess of 9% over 5.5% is 3.5%,
          which
          is greater than the maximum protection percentage of 3%. Therefore, the
          class
          will receive an additional payment of only one-twelfth of 3% of $1.6 million,
          or
          $4,000.

        The
          yield
          maintenance payments for each class of yield protected certificates will
          be made
          to the paying agent, who will pass them through to the holders of the class
          of
          certificates in proportion to the principal balances of their certificates,
          but
          not more than will be required to pay the certificates an amount (the yield
          maintenance amount) for that distribution day equal to the yield
          maintenance percentage of the actual principal balance for the class for
          that
          distribution day.

        Example:
          Same as previously, with LIBOR 6.3%, but an assumed principal balance of
          $3
          million, which exceeds the actual principal balance of $2 million. The
          yield
          maintenance provider will make a yield maintenance payment to the paying
          agent
          of one-twelfth of 0.8% of $3 million (the assumed principal balance), or
          approximately $2,000, but the class will receive only the yield maintenance
          amount of one-twelfth of 0.8% of $2 million (the actual principal balance),
          or
          approximately $1,333.

        If
          for
          any distribution day, the yield maintenance payment by the yield maintenance
          provider to the paying agent for a class of certificates exceeds the yield
          maintenance amount required to be paid to the holders of that class, the
          excess
          will be deposited in a yield maintenance reserve fund for that class
          maintained in an account at the paying agent.

        If
          for
          any distribution day, the assumed principal balance is less than the aggregate
          outstanding principal balance of a class of yield protected certificates,
          the
          yield maintenance payment will be less than the yield maintenance amount
          for the
          distribution day, and a shortfall will result. Amounts in the yield maintenance
          reserve fund for the class will be used to cover such shortfall.

        Once
          the
          principal balance of a class of yield protected certificates has been reduced
          to
          zero, or the Trust or the related yield maintenance agreement has been
          terminated, any funds remaining in the yield maintenance reserve fund will
          be
          paid to [underwriter]. Thereafter, any payments resulting from the yield
          maintenance agreement for the class will be paid to [underwriter].

        The
          yield
          maintenance reserve fund may not be invested.

        The
          yield
          maintenance reserve fund will be treated as an “outside reserve fund” under the
          REMIC provisions, beneficially owned by [underwriter], who will be taxable
          on
          all such amounts or income thereon, and who will be entitled to any
          reimbursement from the REMICs with respect thereto.

        28.2
          Tax treatment

        CitiMortgage
          will treat the portion of the Trust that holds the right of the yield protected
          certificates to receive payments under the yield maintenance agreement
          and the
          yield maintenance reserve fund as a grantor trust for federal income tax
          purposes. The yield maintenance agreement and the yield maintenance reserve
          fund
          are not assets of any REMIC.

        CitiMortgage
          will treat the holders of the yield protected certificates as the beneficial
          owners of a notional principal contract representing the right to receive
          payments under the yield maintenance agreement and [underwriter] as the
          beneficial owner of the yield maintenance reserve fund, including any payments
          under the yield maintenance agreement that exceed the payments distributable
          to
          the holders of the yield protected certificates.

        Based
          on
          information provided annually by CitiMortgage with respect to the yield
          protected certificates, CitiMortgage will report annually to the holders
          of the
          yield protected certificates and to the IRS (as attachments to Form 1041
          or
          other applicable form) their allocable shares of income and expense with
          respect
          to their right to receive payments under the yield maintenance agreement
          under
          the rules applicable to notional principal contracts, taking into account
          the
          portion of the original issue price of the yield protected certificates
          allocable to their right to receive payments under the yield maintenance
          agreement, and treating each holder of yield protected certificates as
          if it
          were an original holder.

        CitiMortgage
          will not vary the investment of the holders of the yield protected certificates
          to take advantage of variations in market rates of interest to improve
          their
          rates of return.

Definitions
          and
          usages

         

        1.1
          Defined terms

        In
          this
          agreement, the following words and phrases have the following
          meanings:

        accrual
          termination day: For an accrual class, the earlier of (1) the first
          distribution day on which the principal balance of each of its accrual
          directed
          classes on the preceding day is zero, or (2) the subordination depletion
          date.

        affiliate:
          For a specified person, any other person that controls, is controlled by
          or is
          under common control with the specified person. In this definition, “control” of
          a specified person means the power to direct the management and policies
          of the
          person, directly or indirectly, whether through the ownership of voting
          securities, by contract or otherwise; and the terms “controlling” and
“controlled” have correlative meanings.

        affiliated
          servicing fee rate: 0.25% per annum. The monthly affiliated
          servicing fee rate is one-twelfth of the affiliated servicing fee
          rate.

        aggregate
          outstanding advances: For a determination date, the aggregate of net
          servicing account advances, net voluntary advances, net Paying Agent advances
          and advance account advances made from the cut-off date to the determination
          date, plus any uncommitted cash advances to be made on the next distribution
          day.

        appraisal:
          For a mortgage loan, the appraisal conducted in connection with the origination
          of the mortgage loan, whether originated upon the purchase of the related
          mortgaged property or in connection with a refinancing.

        Authorized
          Officer: For CitiMortgage or CMSI, the Chairman of the Board of Directors,

          foregoing officers and furnished to the Trustee and, solely in the case
          of a
          statement given pursuant to section 3.22, any Servicing Officer.

        Bankruptcy
          Code: The United States Bankruptcy Code of 1978.

        bankruptcy
          coverage termination date: If there is a bankruptcy loss limit, the
          distribution day on which the bankruptcy loss limit has been reduced to
          zero or
          a negative number (or the subordination depletion date, if
          earlier).

        bankruptcy
          loss: For a mortgage loan, (1) a debt service reduction or (2) a
          deficient valuation, unless, in either case, CitiMortgage has notified
          the Trustee that CitiMortgage is diligently pursuing any remedies that
          may exist
          in connection with the representations and warranties made regarding the
          related
          mortgage loan and either (A) the related mortgage loan is not in default
          with regard to payments due thereunder, or (B) delinquent payments of
          principal and interest under the related mortgage loan, and any premiums
          on any
          applicable hazard insurance policy and any related escrow payments for
          the
          mortgage loan, are being advanced on a current basis without giving effect
          to
          any debt service reduction.

        bankruptcy
          loss limit: If an initial bankruptcy loss limit is stated in the Series
          Terms, for a distribution day, the initial bankruptcy loss limit minus
          the
          aggregate amount of bankruptcy losses

        since
          the
          cut-off date. The bankruptcy loss limit may be further reduced by CitiMortgage
          (including accelerating the manner in which such coverage is reduced) provided
          that prior to the reduction, each rating agency confirms in writing to
          CitiMortgage (with a copy to the Trustee) that the reduction will not adversely
          affect the rating agency’s then-current rating of any class of
          certificates.

        beneficial
          owner: For a certificate held by a Clearing Agency, the person who is the
          beneficial owner of the certificate as reflected on the Clearing Agency’s books

        provisions”
          above, and for residual certificates, all residual certificates having

          percentage: For one or more classes, the ratio of the aggregate of the
          principal balances of the classes to the aggregate of the principal balances
          of
          all classes of the series, expressed as a percentage.

        classes
          A-x through A-y: For a positive integer x and a greater integer
y, each class A-z for all integers z from x
          through y, inclusive. Example: “classes A-3 through A-5” means
          each of classes A-3, A-4, and A-5. If a class is designated with an integer

        Clearing
          Agency: An organization registered as a “clearing agency” pursuant to

        Clearing
          Agency Participant: A broker, dealer, bank other financial institution or
          other person for whom a Clearing Agency effects book-entry transfers and

          payment received on the mortgage loan for the month (including accrued
          interest
          due but not received from liquidation or insurance proceeds for liquidated
          loans) over the amount of interest on the mortgage loan for the month at
          the
          pass-through rate, up to the servicing fee CitiMortgage is permitted to
          retain
          under this agreement.

        debt
          service reduction: For a mortgage loan, a reduction in the scheduled
          monthly loan payment for the mortgage loan by a court of competent jurisdiction
          in a proceeding under the Bankruptcy Code or any similar state law, except
          a
          reduction that would constitute a deficient valuation. If the court proceeding
          results in an increase in the scheduled payment for a month (for example,
          a
          final balloon payment or a payment in a month after the originally scheduled
          maturity of the mortgage loan), the increased payment will be considered
          a
          scheduled payment and not a debt service reduction.

        Example:
          Suppose a homeowner has a mortgage loan with an outstanding principal balance
          of
          $50,000 and an interest rate of 7%. The loan has 10 years to run. The homeowner
          files for bankruptcy, and the bankruptcy court (1) reduces the outstanding
          principal balance to $40,000, (2) reduces the interest rate to 6%, and
          (3) stretches the payments out to 20 years. Then

        ·      the
          $10,000 reduction in principal owed is a bankruptcy loss, and

        ·      the
          difference between the monthly payment the homeowner would have made on
          the
          remaining $40,000 at the original interest rate and maturity, and the monthly
          payment the homeowner is now required to make on the new lower interest
          rate and
          extended maturity, is a debt service reduction, and

        ·      payments
          in the final 10 years (that is, after the originally scheduled maturity)
          will be
          scheduled payments.

        deficient
          valuation: For a mortgage loan, a valuation by a court of
          competent

        jurisdiction
          of the mortgaged property in an amount less than the then-outstanding
          indebtedness under the mortgage loan, or a reduction in the scheduled monthly
          principal payment that results in a permanent forgiveness of principal,
          which
          valuation or reduction results from a proceeding under the Bankruptcy Code
          or
          any similar state law.

          loan
          became a liquidated loan, over

        ·      the
          net liquidation proceeds for the mortgage loan.

        Each
          liquidated loan loss will have an interest portion and a principal portion.
          If
          net liquidation proceeds for the mortgage loan exceed the accrued interest
          described in clause (B) above, the interest portion of the liquidated loan
          loss will be zero; otherwise, the interest portion of the liquidated loan
          loss will be the excess of the accrued interest described in clause (B)
          above
          over such net liquidation proceeds. The principal portion of a liquidated

        Participant:

        pass-through
          rate: For a mortgage loan for any date or period, the applicable mortgage
          note rate, minus

        
          	
                  ·

                	
                  for
                    an affiliated mortgage loan, the affiliated servicing fee rate,
                    and

                    fee rate
                    and the master servicing fee rate.

                

        

        Any
          regular monthly remittance of interest at the pass-through rate for a mortgage
          loan is based upon annual interest at that rate on the scheduled principal
          balance as of the first day of the month of the mortgage loan divided by
          twelve.
          Interest at the pass-through rate will be computed on the basis of a 360-day
          year, each month being assumed to have 30 days. The monthly
          pass-through rate will be one-twelfth of the pass-through rate.

        (Any
          partial remittance of interest at such rate by reason of a full principal
          prepayment is based upon annual interest at that rate on the prepaid principal
          balance of the related mortgage loan, multiplied by a fraction the numerator
          of
          which is the actual number of days elapsed in the month of the prepayment
          to the
          date of the prepayment, and the denominator of which is 360. For affiliated
          mortgage loans, and some or all of the third-party mortgage loans, the
          mortgagor
          is not required to pay interest on a partial principal prepayment that
          is
          received during a month. The amounts required to be paid pursuant to section
          3.4
          are in addition to any interest payments made by mortgagors and passed
          through
          on full and partial prepayments.)

        percentage
          interest: For a class of residual certificates, if the residual certificate
          has a principal balance as specified in the Series Terms, the ratio of
          the
          initial principal balance of the residual certificate to the aggregate
          initial
          principal balance of the entire class, expressed as a percentage; if the
          residual certificate does not have a principal balance, the portion represented
          by such residual certificate (expressed as a percentage) of the total ownership
          interest in the applicable constituent REMIC represented by all residual
          certificates of the class. For a certificate of an IO class, the ratio
          of the
          notional balance of the certificate to the aggregate notional balance of
          the
          entire class.

          less

          the then
          current credit standing of the obligor under such guaranteed investment
          contract
          is such that continued investment pursuant to such contract of funds included
          in

          and be
          entitled to the return of all funds previously invested thereunder, together

          notice of
          such potentiality from the provider of the GIC which must be obligated
          to give
          such notice at least once per year; provided, further, that upon any such
          event
          CMSI, by written notice to the Trustee or the Paying Agent, may replace
          such
          contract with a substitute GIC having substantially the same terms (including
          without limitation a rate of return at least as high as the contract being
          replaced) so long as such substitute contract has an obligor with a credit
          standing no less than the credit standing of the obligor under the contract

          be replaced at the time the contract was executed and such fact is certified
          by
          CMSI to the Trustee or the Paying Agent;

        (d)                  provide

          trustee hereunder;

        (e)        provide
          that the funds invested thereunder and accrued interest thereon be available
          not
          later than the day prior to any distribution day on which such funds may
          be
          required for distribution hereunder; and

          will be satisfied in connection with such registration:

        (a)        the
          instruments governing the creation and operation of the nominee provide
          that
          neither the nominee nor any owner of an interest in the nominee (other

          Trustee or the Paying Agent) will have any interest, beneficial or otherwise,
          in
          any Eligible Investments held in the name of the nominee, except for the
          purpose
          of transferring and holding legal title thereto;

          Eligible Investments held in the name of the nominee are to be held by
          the
          nominee as agent (other than commission agent or broker) or nominee for
          the
          account of the Trustee; and

          effect a valid registration of transfer of such Eligible Investment are
          complied
          with as evidenced to the Trustee and the Paying Agent upon its request
          by an
          opinion of counsel.

        ratio-stripped
          IO class: An IO class with an initial notional balance equal to the initial
          notional balance of one or more IO strips, and that receives interest
          distributions solely from distribution on those strips.

        ratio-stripped
          IO loan: For any premium loan with a pass-through rate greater than the
          target rate, a single hypothetical IO loan that, combined with a single
          hypothetical target-rate loan, has the same interest and principal payments
          as
          the premium loan.

        Example:
          For a premium loan with a $100,000 principal balance and a pass-through
          rate 1%
          per annum greater than the target rate, the (hypothetical) ratio-stripped
          IO
          loan will have a notional balance of $100,000 and a pass-through rate of
          1% per
          annum, and the (hypothetical) target-rate loan will have a principal balance
          of
          $100,000 and a pass-through rate equal to the target rate.

        ratio-stripped
          PO class: A PO class whose initial principal balance equals the initial
          principal balance of one or more PO strips (rounded down to the nearest
          whole
          dollar), and that receives principal distributions solely from distribution
          on
          those strips, or from reimbursements from subordinated classes.

        ratio-stripped
          PO loan: For any discount loan, a single hypothetical PO loan that,
          combined with a single hypothetical target-rate loan, has the same interest
          and
          principal payments as the original discount loan.

        Example:
          For a discount loan with a $100,000 principal balance and a pass-through
          rate 1%
          per annum less than the target rate of 5% per annum, the (hypothetical)
          ratio-stripped PO loan will have a principal balance of $20,000 and a
          pass-through rate of 0%, and the (hypothetical) target-rate loan will have
          a
          principal balance of $80,000 and a pass-through rate equal to the target
          rate.

          losses: For a distribution day,

        ·      liquidated
          loan losses (including special hazard losses and fraud losses) and bankruptcy
          losses incurred in the preceding month. For a realized loss consisting
          of a
          liquidated loan loss, the interest and principal portions of
          the realized loss will equal the interest and principal portions of the
          liquidated loan loss; and

        ·      reductions
          in the principal balance of mortgage loans as part of loan modifications
          pursuant to section 3.19.

        reasonably
          foreseeable default: CitiMortgage has contacted the mortgagor, has
          evaluated the mortgagor’s current ability to make scheduled monthly loan
          payments, and has a reasonable basis for determining that the mortgagor
          is
          unlikely to make one or more scheduled monthly loan payments in the foreseeable
          future.

        record
          date: For a distribution day, the close of business on (a) for a LIBOR
          class, the last day (whether or not a business day) of its last LIBOR accrual

          connection with all calculations required to be made pursuant to this agreement
          for remittances on any mortgage loan, any payments on the mortgage loans

        2.1
          Transfer of mortgage loans

        (a) CMSI,
          as of the closing date, hereby transfers and assigns to the Trustee, without
          recourse, all of CMSI’s right, title and interest in and to

        ·      the
          mortgage loans, including all remittances received or receivable by CMSI
          on or
          with respect to the mortgage loans (other than payments of principal and
          interest due and payable on the mortgage loans, and principal prepayments
          thereon received, on or before the cut-off date), and

        ·      the
          proceeds of any title, primary mortgage, hazard or other insurance policies
          related to the mortgage loans.

        Such
          transfer and assignment is absolute, is made in exchange for the certificates
          described in this section 12,

        and
          is
          intended by the parties to be a sale. Nonetheless, to the extent such transfer
          is held not to be a sale under applicable law, it is intended that this
          agreement will be a security agreement under applicable law, and CMSI will
          be
          deemed to have granted to the Trustee, for the benefit of the certificate
          holders and any Insurer, a security interest in the Trust Fund, including
          the
          mortgage loans, mortgage notes and related documents. CMSI will, at its
          own
          expense, take any action reasonably requested by the Trustee to confirm,
          perfect, and protect the priority of, the security interest granted hereby,
          including the filing of Uniform Commercial Code financing statements in
          the
          appropriate jurisdictions.

        CMSI
          will
          not transfer any other property to the Trust Fund except as expressly permitted
          by this agreement.

        The
          Trustee acknowledges receipt of the documents and other property referred
          to in
          section 2.1, and declares that the Trustee 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
          certificate holders and any Insurer.

        (b) The
          Trustee and CitiMortgage have entered into a Mortgage Note Custodial
          Agreement substantially in the form of exhibit C with the Mortgage Note
          Custodian named in section 12.1.

        The
          Mortgage Note Custodian may be the Trustee, any affiliate of the Trustee,
          an
          affiliate of CMSI, or an independent entity, except that if the rating
          of the Mortgage Note Custodian’s long-term senior debt is

        
          	
                  ·

                  rated
                    below A2, or is not rated, by Moody’s if Moody’s is a rating agency,
                    or

                

        

        
          	
                  ·

                	
                  rated
                    below A+, or is not rated, by S&P if S&P is a rating
                    agency,

                

        

        then
          the
          Trustee shall, reasonably promptly after being notified by CitiMortgage,
          CMSI or
          a rating agency that the Mortgage Note Custodian no longer has the required
          ratings, remove the Mortgage Note Custodian and appoint a successor Mortgage
          Note Custodian, as described in the following paragraph.

        The
          Trustee may at any time remove the initial or any successor Mortgage Note
          Custodian, and enter into a Mortgage Note Custodial Agreement substantially
          in
          the form of exhibit C with a successor Mortgage Note Custodian. The Mortgage
          Note Custodial Agreement may provide that the successor Mortgage Note Custodian
          will conduct the review of each mortgage note required under section 2.1(f),
          except that if the successor Mortgage Note Custodian is CMSI or an
          affiliate of CMSI, the Trustee may conduct the review.

        (c) For
          each mortgage loan (other than a mortgage loan secured by shares in a
          cooperative housing corporation), CMSI will on or before the closing date
          deliver

        ·      to
          the Mortgage Note Custodian the mortgage note, endorsed by manual or facsimile
          signature without recourse by the Originator or an affiliate of the Originator
          in blank or to the Trustee showing a complete chain of endorsements from
          the
          named payee to the Trustee or from the named payee to the affiliate of
          the
          Originator and from such affiliate to the Trustee, except that endorsement
          is
          not required where Mortgage Electronic Registration Systems, Inc.
          (MERS) is the named payee or the nominee of the named payee,
          and

        ·      to

          the public recording office retains the original.

        (ii) Any
          original assumption, modification, buydown or conversion-to-fixed-interest-rate
          agreement applicable to the mortgage.

          Trustee

          by
          local law, in a blanket assignment or assignments of the mortgage to the
          Trustee, including any intervening assignments and showing a complete chain
          of

          or
          such affiliate and to the Trustee, except that (x) a blanket
          assignment need not be in recordable form but will be delivered with a
          limited
          power of attorney authorizing the Custodian, on behalf of the Trustee,
          to act

          and
          recording in the Trustee’s name any instruments for recording assignments of the

          MERS, only assignments from the origination of the mortgage to its assignment
          to
          MERS will be required, and (z) if the mortgage was originated with MERS as

          assignments from the named payee to the Trustee or from the named payee
          to the
          affiliate of the Originator and from such affiliate to the Trustee,

        (v) The

          for mortgage loans secured by mortgaged properties in the State of New
          Jersey,
          or originated prior to October 1988 and secured by mortgaged properties

          State of New York) the executed UCC-1 financing statement with evidence
          of
          recording thereon and executed original UCC-3 financing statements or other
          appropriate UCC financing statements required by state law, evidencing
          a
          complete and unbroken chain from the mortgagee to the Trustee with evidence

          recording thereon (or in a form suitable for recordation).

        (viii) Any
          related primary mortgage insurance certificate and related policy.

        (e)
          The
          Mortgage Note Custodian will hold the mortgage notes, and CitiMortgage
          will hold
          the other mortgage documents, in trust for the Trustee and the benefit
          of the
          Trustee, any Insurer and all present and future certificate
          holders.

        For
          purposes of this section 2.1, a document (other than a promissory note
          or
          document described in the following sentence) will be deemed “delivered” to a
          person if the person has received, or been granted unrestricted access
          to, an
          image of the document that is inscribed in a tangible medium or is stored
          in an
          electronic or other medium and is retrievable in perceivable form. A letter
          of
          credit, investment security or similar instrument that in the ordinary
          course of
          business is transferred by delivery with any necessary endorsement or assignment
          may only be delivered in electronic form if

        ·      the
          document is a security certificate, and applicable state law provides that
          a
          security interest may only be perfected by filing of a financing statement,
          or

        ·      all
          applicable steps have been taken in accordance with CitiMortgage’s underwriting
          policies to confirm in the Trustee a first priority perfected security
          interest
          in the document or the rights represented by the document.

        (f)
          Pursuant to the Mortgage Note Custodial Agreement, the Mortgage Note Custodian
          will review each mortgage note within 90 days after the closing date to
          ascertain that it has been executed and received, and that such note relates
          to
          the mortgage loans identified in exhibit B.

        (g) On
          or before the closing date, CMSI will deposit in the certificate
          account

        ·      all
          payments on the mortgage loans that CMSI receives after the cut-off date
          and
          before the closing date, to the extent such payments are being transferred
          and
          assigned to the Trustee under this agreement, except any portion of such
          payments on mortgage loans (including servicing fees) of a type not required
          to
          be deposited therein as specified in section 6 or the Series Terms,
          and

        ·      any
          amount required to be so deposited under the Series Terms.

        (h) If
          CMSI is required under this section 2.1 to deliver an original recorded
          mortgage
          or a completed assignment in recordable form to CitiMortgage by the closing
          date, but cannot do so because of a delay in recording the mortgage, CMSI
          may
          instead

        ·      deliver
          a copy of the mortgage, 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 insurance

        
          
             

          

          
            55

            
              

            

          

          
             

          

        

        or
          binder
          therefor (which may be a certificate relating to a master policy of title
          insurance), and

        ·      an
          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 CitiMortgage promptly upon receipt of such
          mortgage.

        If
          an
          original recorded mortgage has been lost or misplaced, CMSI or the related
          title
          insurance company may deliver, in lieu of the mortgage, a copy of the mortgage
          bearing recordation information and certified as true and correct by the
          office
          in which the original mortgage was recorded.

        If
          CMSI
          cannot deliver the original or a copy of a title insurance policy (which
          may be
          a certificate relating to a master policy of title insurance) for a mortgaged
          property to CitiMortgage by the closing date because the policy is not
          yet
          available, CMSI may instead deliver a binder for the policy, and deliver
          the
          original or a copy of the policy to the Trustee when available.

        If
          CMSI
          cannot deliver an original assumption, modification, buydown or
          conversion-to-fixed-interest-rate agreement to CitiMortgage by the closing
          date,
          CMSI may instead 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
          will, at its own expense, prepare and deliver to CitiMortgage each assignment
          referred to in this section 2.1(h) as soon as practicable but not later
          than 60
          days after the date of initial issuance of the certificates. For each mortgage
          relating to a mortgaged property located in a state for which the rating
          agencies require recordation of such assignments (as will be specified
          in the
          Series Terms or a CMSI officer’s certificate), CMSI intends to record the
          assignment in the appropriate public office for real property records (or
          supply
          CitiMortgage with evidence of recordation) as soon as practicable after
          the
          initial issuance of the certificates. Except as provided in this section,
          neither CMSI nor any Originator or affiliate of any Originator will have
          any
          obligation to record any assignment of any mortgage in order to name the
          Trustee
          as mortgagee of record. The preceding sentence will not be in derogation
          of the
          obligation of CMSI, the Originators and affiliates of the Originators to
          record
          (and supply CitiMortgage with evidence thereof) assignments of mortgages
          required in order that CMSI, an Originator or an affiliate of an Originator
          be
          shown as mortgagee of record of each mortgage.

        CMSI
          will, at its own expense, file any UCC-3 financing statements not previously
          filed, and will supply CitiMortgage with evidence of the filing. CMSI intends
          to
          file in the appropriate public office as soon as practicable after the
          initial
          issuance of the certificates.

        For
          mortgage loans that have been prepaid in full after the cut-off date and
          prior
          to the closing date, CMSI, in lieu of delivering documents to the Mortgage
          Note
          Custodian and CitiMortgage, will on the closing date deliver a certification
          of
          a Servicing Officer as set forth in section 3.13.

        (i)
          Concurrently with the transfer and assignment to the Trustee of the mortgage
          loans, the Trustee or the Authenticating Agent will, in accordance with
          a
          written order or request signed in CMSI’s name by an Authorized
          Officer,

        
          
             

          

          
            56

            
              

            

          

          
             

          

        

        authenticate
          and deliver to or upon CMSI’s order, duly authenticated certificates in
          authorized denominations evidencing the entire ownership of the Trust Fund.
          The
          Trustee acknowledges that to the extent it holds any class P or class L
          regular
          interests, it holds such regular interests as assets of the lower-tier
          or
          upper-tier REMIC, as described in the Series Terms.

         

        2.2
          CMSI’s representations and warranties 

        CMSI
          represents and warrants to the Trustee and any Insurer that as of the closing
          date:

        (i)        The
          information in exhibit B was true and correct in all material respects
          as of the
          dates respecting which such information is furnished, and the information
          provided to the rating agencies, including the loan-level detail, is true
          and
          correct according to rating agency requirements.

        (ii)        As
          of the closing date, each mortgage will be a valid first lien on the property
          securing the related mortgage note subject only to

        ·      the
          lien of current real property taxes and assessments as limited in clause
          (vi)
          below,

        ·      covenants,
          conditions and restrictions, rights of way, easements and other matters
          of
          public record as of the date of recording of the mortgage, which exceptions
          appearing of record are acceptable to mortgage lending institutions generally
          or
          specifically reflected in the appraisal obtained in connection with the
          origination of the related mortgage loan,

        ·      other
          matters to which like properties are commonly subject that do not in the
          aggregate materially interfere with the benefits of the security intended
          to be
          provided by the mortgage, and

        ·      for
          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
          before the transfer and assignment 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,
          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 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
          not
          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 closing date, there is no mechanics’ lien or claim for work, labor or
          material affecting the mortgaged property that is or may be a lien prior
          to, or
          equal with, the lien of the mortgage except those that are insured against
          by
          the title insurance policy referred to in (x) below;

        (vi)                  As
          of the closing date, there is no delinquent tax or assessment lien against
          any
          mortgaged property;

        (vii)                  As
          of the closing date, there is no valid offset, defense or counterclaim
          to any
          mortgage note or mortgage, including the obligation of the
          mortgagor

          pay
          the unpaid principal and interest on the mortgage note;

        (viii)                  As
          of the closing 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, local and federal laws, including, without limitation,

          for
          certain mortgage loans originated before 1995, 90%) of its original value
          is
          covered by primary mortgage insurance at least until its outstanding principal
          balance is less than or equal to 80% of the original value, either through
          principal payments by the mortgagor or as determined by a new appraisal
          delivered subsequent to origination. So long as it is in effect, the primary
          mortgage insurance covers losses from defaults in an amount equal to the
          excess,
          of the outstanding principal balance of the mortgage loan over 75% of the
          original value of the mortgage loan;

        (xiii)                  The
          original principal balance of each mortgage loan was not more than 95%
          of the
          original value of the mortgage loan;

        (xiv)
          For
          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;

        (xv) Each
          mortgage loan is a “qualified mortgage” within the meaning of Section 860G(a)(3)
          of the Internal Revenue Code.

        (xvi) For
          each mortgaged property at the time the mortgage loan was originated, no
          improvement located on or part of the mortgaged property
          violated

        
          
             

          

          
            58

            
              

            

          

          
             

          

        

        any
          applicable zoning or subdivision
          laws or ordinances.

        (xvii) For
          each mortgaged property, the terms of the mortgage note and the mortgage
          loan
          have not been impaired, altered or modified in any material respect, except
          by a
          written instrument which has been recorded or is in the process of being
          recorded.

        (xviii) For
          each mortgaged property, no default or waiver exists under the mortgage
          documents, and no modifications to the mortgage documents have been made,
          that
          have not been disclosed.

        (xix) If
          a mortgaged property is in a Federal Emergency Management Agency designated
          flood area, a flood insurance policy is in effect covering the mortgaged
          property.

        (xx) For
          each mortgaged property as of the closing date, a hazard insurance policy
          is in
          place.

        The
          representations and warranties in this section 2.2 will survive delivery
          of the
          mortgage files to the Trustee.

         

        2.3
          Repurchase or substitution of mortgage loans 

        (a)
          Each
          of CMSI, CitiMortgage and the Trustee will promptly notify the other parties
          if
          it discovers a breach of any of the representations and warranties in section
          2.2 that materially and adversely affects the interests of the certificate
          holders or any Insurer in a mortgage loan (including a mortgage loan substituted
          for a nonconforming mortgage loan pursuant to section 2.4) (a material
          breach).

        (b)
          If
          CMSI is notified of a material breach, CMSI will have 60 days after the
          notice
          (or a longer period approved in advance in writing by a Responsible Officer
          of
          the Trustee) to cure the breach in all material respects, or to repurchase
          the
          mortgage loan or substitute eligible substitute mortgage loans, as provided
          in
          this section 2.3.

        Except
          as
          expressly provided in this agreement, neither the Mortgage Note Custodian
          nor
          CitiMortgage is required to inspect or review any document in a mortgage
          file.
          However, if the Mortgage Note Custodian finds that a mortgage note is missing
          or
          materially defective, the Mortgage Note Custodian will promptly notify
          CitiMortgage and CMSI by e-mail. CMSI will then have 180 days after the
          notice
          to cure the breach in all material respects, or to repurchase the mortgage
          loan
          or substitute eligible substitute mortgage loans, as provided in this section
          2.3, except that CMSI will only have 90 days after the notice to cure,
          cure,
          repurchase, or substitute if the defect causes the mortgage loan to fail
          to be a
“qualified mortgage” under Internal Revenue Code section
          860G(a)(3).

        (c)
          Any
          repurchase by CMSI of a mortgage loan will be at a price equal to

        (i) 100%
          of the scheduled principal balance of the mortgage loan on the date of
          repurchase, plus

        (ii) accrued
          and unpaid interest thereon at the pass-through rate to the first day of
          the
          following month, plus

        (iii) any
          costs and damages incurred by the Trust Fund in connection with any violation
          by
          such mortgage loan of any predatory lending law, plus

        (iv) aggregate
          outstanding advances for the mortgage loan, to the extent not recovered
          in (ii)
          above.

        (d)
          CMSI
          will pay the repurchase price to CitiMortgage, which will promptly deposit
          the
          repurchase price in the certificate account. A repurchase of a mortgage
          loan
          under this section 2.3 will be considered a prepayment in full of the mortgage
          loan on the date of repurchase. Upon the Trustee’s receipt of written notice of
          the deposit signed by an

        
          
             

          

          
            59

            
              

            

          

          
             

          

        

        Authorized
          Officer of CitiMortgage, the Trustee will direct the Mortgage Note Custodian
          and
          CitiMortgage to release the related mortgage file to CMSI and will execute
          and
          deliver such instruments of transfer or assignment furnished to the Trustee,
          in
          each case without recourse, as CMSI reasonably requests, to vest the mortgage
          loan in CMSI. Repurchase of the mortgage loan by CMSI will be deemed to
          include
          the right to receive any remittance on the mortgage loan payable or received
          on
          or after the date of repurchase, and CitiMortgage will, upon receipt, promptly
          pay CMSI the amount of any such remittance.

        (e)
          CMSI
          may, instead of repurchasing a mortgage loan pursuant to this section 2.3,
          substitute one or more eligible substitute mortgage loans (as defined below)
          for
          one or more nonconforming mortgage loans. Such a substitution will take
          place on
          a business day designated by CMSI (the substitution day) occurring
          before the second anniversary of the startup day, subject to satisfaction
          of the
          conditions in section 2.1 and the following conditions:

        (i)        no
          Event of Default is continuing; and

        (ii)        the
          aggregate scheduled principal balance of all eligible substitute mortgage
          loans
          substituted on the substitution day (determined for each eligible substitute
          mortgage loan as of the substitution day) does not exceed 40% of the aggregate
          scheduled principal balance of all mortgage loans as of the closing
          date;

        (f)
          An
eligible substitute mortgage loan: is a mortgage loan

        ·      for
          which all payments of principal and interest due on or before the substitution
          day have been received,

        ·      
          that has a mortgage note rate equal to or greater than the highest mortgage
          note
          rate of any mortgage loan for which it is being substituted,

        ·      that
          matures no later than, and no more than one year before, any mortgage loan
          for
          which it is being substituted,

        ·      that
          has an original term to maturity equal to each mortgage loan for which
          it is
          being substituted, and

        ·      that
          has a scheduled principal balance that, together with any other eligible
          substitute mortgage loans being substituted on that substitution day, and
          any
          funds CMSI deposits in the certificate account relating to the substitution
          (the substitution adjustment amount) equals or exceeds the mortgage
          loans for which they are being substituted.

        The
          substitution adjustment amount will be separately accounted for as a reserve
          fund in the certificate account and will be remitted to certificate holders
          in
          the month following receipt when the repurchase proceeds are remitted to
          compensate for the resulting shortfall incurred in connection with the
          substitution of mortgage loans.

        (g)
          If,
          on the substitution day, any installment of principal and interest has
          been
          received in the certificate account where the principal portion has not
          been
          applied to reduce the scheduled principal balance of the mortgage loan
          that is
          being substituted for, because the installment was received before the
          first day
          of the applicable month, the full amount of such prepaid installment will
          be
          paid on the substitution day to CMSI from the certificate account.

        (h)
          Upon
          a substitution of mortgage loans pursuant to this section 2.3,

        ·      exhibit
          B to this agreement will be deemed to be amended to exclude all mortgage
          loans
          being replaced by such eligible substitute mortgage loans and to include,
          pursuant to section 10.1, the information in the supplemental

        
          
             

          

          
            60

            
              

            

          

          
             

          

        

        mortgage
          loan schedule regarding the eligible substitute mortgage loans, and all
          references in this agreement to mortgage loans will include such eligible
          substitute mortgage loans,

        ·      CMSI
          will be deemed to represent and warrant, as of the substitution day, that
          the
          representations and warranties in section 2.2 are true of the eligible
          substitute mortgage loans, and

        ·      the
          Trustee will release to CMSI the nonconforming mortgage loans and execute
          and
          deliver any instruments of transfer or assignment required to transfer,
          without
          recourse, the nonconforming mortgage loans to CMSI.

        (i)
          CMSI’s obligation under this section 2.3 to repurchase or substitute mortgage
          loans will be the sole remedy against CMSI available to the certificate
          holders
          or the Trustee on behalf of the certificate holders for a material defect
          in a
          mortgage document or a breach of a representation and warranty in section
          2.2.

         

        3
Servicing
          

         

        3.1
          CitiMortgage as servicer and master servicer

        (a)
          Affiliated mortgage loans. CitiMortgage will service those mortgage
          loans listed in exhibit B, other than any mortgage loans listed on schedule
          B-TP
          (the affiliated mortgage loans).

        (b)
          Third-party mortgage loans. The mortgage loans listed in schedule B-TP
          to exhibit B (third-party mortgage loans) will be serviced by a
third-party servicer pursuant to this agreement, a third-party
          servicing agreement between CitiMortgage and the third-party servicer, and
          the Guide. CitiMortgage will be the master servicer for each
          third-party mortgage loan. Each third-party servicing agreement will be
          consistent with this agreement and, except for special servicing agreements,
          will be effective as of the closing date.

        (c)
          Special servicing. CitiMortgage may enter into a special servicing
          agreement with an unaffiliated person (the class B holder). At any
          time that the class B holder holds 100% of the beneficial interest in the
          most
          subordinated class of certificates, the class B holder may designate a
          special servicer to service certain mortgage loans in default and REO
          property (specially serviced mortgage loans). Any special servicing
          agreement will be subject to each rating agency’s acknowledgement that the
          ratings of each class of certificates in effect immediately prior to
          CitiMortgage’s entering into the special servicing agreement will not be
          qualified, downgraded or withdrawn, and that no class of certificates will
          be
          placed on credit review status (except for possible upgrading) as a result
          of
          the agreement.

        CitiMortgage
          will be the master servicer and the special servicer will be a third-party
          servicer for the specially serviced mortgage loans. Except as otherwise
          stated
          or as the context clearly requires, references in this agreement to third-party
          mortgage loans will include specially serviced mortgage loans, and references
          to
          third-party servicing agreements will include special servicing
          agreements.

        (d)
          Third-party servicing. With CitiMortgage’s approval, a third-party
          servicer may delegate its servicing obligations, but the third-party servicer
          will remain obligated under its third-party servicing agreement. CitiMortgage
          and any third-party servicer may amend the third-party servicing agreement,
          consistent with this agreement.

        CitiMortgage
          will enforce each third-party servicer’s obligations under its third-party
          servicing agreement,

        
          
             

          

          
            61

            
              

            

          

          
             

          

        

        including
          any obligation to make advances for delinquent payments or to purchase
          a
          mortgage loan on account of defective documentation or a breach of a
          representation or warranty. Such enforcement, including the legal prosecution
          of
          claims, termination of third-party servicing agreements, and the pursuit
          of
          other appropriate remedies, will as to form, extent and timing be conducted
          as
          CitiMortgage, in its good faith business judgment, would require if it
          were the
          owner of the mortgage loans. CitiMortgage will pay the costs of enforcement
          at
          its own expense, but will be reimbursed only from

        ·      a
          general recovery resulting from the enforcement only to the extent that
          the
          recovery exceeds all amounts due on the mortgage loans, or

        ·      a
          specific recovery of costs, expenses or attorneys fees against the party
          against
          whom the enforcement is directed.

        (e)
          Servicinggenerally. In connection with its servicing and
          master servicing, CitiMortgage

        ·      may,
          acting alone or through third-party servicers, take any action it deems
          necessary or desirable.

        ·      may
          execute and deliver on behalf of itself, the certificate holders or the
          Trustee
          any instruments of satisfaction or cancellation, or of partial or full
          release
          or discharge and all other comparable instruments, for the mortgage loans
          and
          the related mortgaged properties.

        ·      will
          service and master service the mortgage loans in the best interests of,
          and for
          the benefit of, the certificate holders and any Insurer.

        ·      will
          service the affiliated mortgage loans in accordance with its normal servicing
          procedures for mortgage loans held in its own portfolio.

        ·      will
          master service the third-party mortgage loans, in accordance with prudent
          mortgage loan servicing standards and procedures accepted in the mortgage
          banking industry and in accordance with the Guide.

        ·      will
          promptly notify the Trustee of any circumstance that might adversely affect
          CitiMortgage’s ability to service or master service any mortgage loan or to
          otherwise perform its obligations under this agreement.

        ·      will
          maintain accurate books and records, and an adequate system of audit and
          internal controls, that 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
          will
          be maintained for the period required by the Guide or any longer period
          required
          by law.

        The
          Trustee will furnish CitiMortgage with any powers of attorney and other
          documents reasonably necessary or appropriate, and will take any other
          actions
          that CitiMortgage reasonably requests, to enable CitiMortgage to carry
          out its
          servicing duties.

         

        3.2
          Collections 

        CitiMortgage
          and each third-party servicer will, to the extent consistent with this
          agreement,

        
          	
                  ·

                	
                  follow
                    such normal collection procedures as it deems necessary and advisable,
                    and

                

        

        
          	
                  ·

                	
                  make
                    reasonable efforts to collect all amounts payable on the mortgage
                    loans it
                    services.

                

        

        Consistent
          with the foregoing, CitiMortgage may

        ·      waive
          any late payment charge, prepayment charge or penalty interest in connection
          with the prepayment of a mortgage loan or any assumption fees
          or

        
          
             

          

          
            62

            
              

            

          

          
             

          

        

        other
          fees collected in the ordinary course of servicing the mortgage loan,
          and

        ·      arrange
          with a mortgagor a schedule for the payment of principal and interest due
          and
          unpaid after the applicable first day of the month if CitiMortgage reasonably
          believes that without the arrangement the mortgagor would default on the
          mortgage loan. Regardless of whether such an arrangement is made, the mortgage
          loan will be considered delinquent for all purposes of this
          agreement.

        CitiMortgage
          need not institute litigation to collect any payment if it reasonably believes
          that the cost of litigation is likely to outweigh its economic
          benefit.

         

        3.3
          Certificate and other accounts 

        (a)
          Certificate account. On or before the closing date, CitiMortgage will
          open with Depositories or the Paying Agent one or more certificate accounts
          (collectively, the certificate account). The certificate account will
          include any alternative certificate account. The certificate account will
          be a
          non-interest bearing account unless the Series Terms state that the certificate
          account is an investment account.

        CitiMortgage
          will not commingle funds and other property in the certificate account
          with any
          other funds or property of CitiMortgage or the Trustee. However, in order
          to
          efficiently transfer funds in the certificate account to a distribution
          account,
          CitiMortgage may, on the business day preceding the date funds are to be
          transferred from the certificate account to the distribution account, transfer
          those funds to a commingled clearance account, provided, that if Fitch
          has rated the certificates, CitiMortgage may not so commingle funds unless
          CitiMortgage’s short-term rating, or the short-term rating of any person to whom
          CitiMortgage has delegated servicing under this agreement, by Fitch is
          at least
“F1.” The clearance account will be under CitiMortgage’s sole control, and
          CitiMortgage will maintain adequate records indicating the ownership of
          the
          funds in the clearance account.

        CitiMortgage,
          on behalf of the Trustee, will deposit in the certificate account, within
          one
          business day following receipt and posting, the following amounts received
          by it
          on the affiliated mortgage loans (remittances on the affiliated
          mortgage loans):

        ·      all
          principal payments and prepayments (other than payments due, and principal
          prepayments received, on or before the cut-off date);

        ·      all
          interest payments (other than payments due on or before the cut-off date),
          net
          of any servicing fee retained by CitiMortgage pursuant to section
          3.8(b);

        ·      any
          buydown funds required to be deposited pursuant to section 3.16;

        ·      all
          net liquidation proceeds, other than proceeds to be applied to the restoration
          or repair of the related mortgaged property or released to the related
          mortgagor
          in accordance with normal servicing procedures;

        ·      proceeds
          from the repurchase of a mortgage loan, and the substitution adjustment
          amount
          in connection with an eligible substitute mortgage loan;

        ·      all
          hazard insurance proceeds;

        ·      any
          advance account advance;

        ·      any
          loss recoveries; and

        ·      the
          amount CitiMortgage is required to pay into the certificate account pursuant
          to
          section 3.4, “Prepayment interest shortfalls.”

        If
          CitiMortgage must repay any amount deposited in the certificate account,
          by
          reason of the reversal of a provisional credit owing to the
          dishonor

        of
          a
          mortgagor’s check or otherwise, CitiMortgage will promptly

        ·      withhold
          a corresponding amount from a subsequent deposit into the certificate account,
          and

        ·      restate
          its accounts appropriately.

                  ·

                	
                  amounts
                    required to be deposited into the servicing
                    account,

                  collected
                    servicing fees, except as required by section 3.4, “Prepayment interest
                    shortfalls,”

                

        

        
          	
                  ·

                	
                  collected
                    prepayment charges, late payment charges, assumption fees and
                    other
                    similar charges, which CitiMortgage may retain as additional
                    servicing
                    compensation, and

                

        

        
          	
                  ·

                	
                  reimbursements
                    of servicing advances,

                

        

        received
          on affiliated mortgage loans.

        (b)
          Servicing accounts. CitiMortgage will establish and maintain
servicing accounts with Depositories, and will deposit therein all
          collections of taxes, assessments, primary mortgage or hazard insurance
          premiums
          or comparable items for the account of the mortgagors. CitiMortgage may
          withdraw
          funds from the servicing account, but only

        ·      to
          effect payment of taxes, assessments, primary mortgage or hazard insurance
          premiums or comparable items,

        ·      to
          reimburse the relevant servicer for costs incurred in effecting the timely
          payment of taxes and assessments on a mortgaged property, for servicing
          account
          advances, and for payments made pursuant to section 3.1 regarding timely
          payment
          of taxes and assessments, section 3.10 regarding premiums on primary mortgage
          insurance policies, and section 3.11 regarding premiums on standard hazard
          insurance policies, or

        ·      to
          refund to a mortgagor any amounts 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 9.1.

        The
          servicing account may commingle collections from other series that have
          the same
          Trustee. The servicing account will be a non-interest bearing account unless
          the
          Series Terms state that the servicing account is an investment
          account.

        Any
          costs
          incurred by the relevant servicer in effecting the timely payment of taxes
          and
          assessments on a mortgaged property will not, for the purpose of calculating
          monthly distributions to certificate holders, be added to the amount owing
          under
          the related mortgage loan, even if the terms of the mortgage loan so
          permit.

        (c)
          Third-party accounts. CitiMortgage will establish and maintain with
          Depositories segregated custodial accounts for P&I and segregated
escrow accounts in accordance with the requirements of the Guide.
          Each
          third-party servicer will deposit in such accounts, within two business
          days of
          receipt and posting, the amounts related to the third-party mortgage loans
          required by the third-party servicing agreements to be so deposited. Amounts
          in
          a custodial account for P&I will be fully insured by the FDIC or the
          National Credit Union Share Insurance Fund. To the extent amounts in a
          custodial
          account for P&I are not fully insured, the excess will either, at
          CitiMortgage’s option,

        ·      be
          promptly remitted to the certificate account or a custodial investment
          account,
          or

        ·      be
          secured by one or more Eligible Investments maturing not later than the
          determination date, provided that the Trustee has received an opinion of
          counsel
          acceptable to the Trustee to the

        
          
             

          

          
            64

            
              

            

          

          
             

          

        

        effect
          that CitiMortgage has either a claim to the funds held by the institution
          or a
          perfected first security interest against such Eligible Investments superior
          to
          the claims of any other depositor or general creditor of such
          institution.

        Proceeds
          received on individual third-party mortgage loans from a title, hazard
          or other
          insurance policy covering the mortgage loan, other than a primary mortgage
          insurance policy, will 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 primary mortgage insurance policies will be deposited
          in the custodial account for P&I and will be applied to the balances of the
          related third-party mortgage loans as payments of interest and
          principal.

        Third-party
          servicers may withdraw funds from custodial accounts for P&I as permitted by
          this agreement and in accordance with the Guide. The Trustee will have
          no
          responsibility for monitoring such withdrawals.

        CitiMortgage
          will maintain separate accounting on a mortgage loan-by-mortgage loan basis
          for
          any remittances to or payments from the custodial accounts for
          P&I.

        (d)
          Transfers from third-party accounts to certificate account. On each
          determination date, each third-party servicer will withdraw from its custodial
          accounts for P&I and deposit into the certificate account the following
          amounts (remittances on third-party loans):

        ·      scheduled
          installments of principal and interest on the third-party mortgage loans
          received by the third-party servicers that were due on the first day of
          that
          month, net of third-party servicing fees due third-party servicers;

        ·      principal
          prepayments and insurance proceeds, net of third-party servicing fees due
          third-party servicers, received in the preceding month;

        ·      liquidation
          proceeds on a third-party mortgage loan.

        (e) Accounts
          generally. The certificate account, the servicing account, each custodial
          account for P&I, the escrow account and the distribution account will each
          bear a designation clearly indicating that the funds in the account are
          held for
          the benefit of the Trustee or the certificate holders. CitiMortgage, each
          third-party servicer, and the Paying Agent will hold all money and property
          received by it as part of the Trust Fund and will apply it as provided
          in this
          agreement, except that amounts from buydown funds required to be
          deposited pursuant to section 3.16 will be held by CitiMortgage in the
          buydown
          account on behalf of the mortgagors, subject to withdrawal by CitiMortgage
          for
          the purposes set forth in sections 3.6(b) and (c).

        The
          certificate account, the servicing account, each custodial account for
          P&I,
          the escrow account and the distribution account will each at all times
          be
          maintained at a bank that is rated a minimum of A-2 (or BBB+ or above if
          it has
          not short-term rating) by S&P. If such an account is held at a bank that
          fails to maintain such a rating, CitiMortgage will move the account within
          30
          days to a bank that does have such a rating.

         

        3.4
          Prepayment interest shortfalls

        (a)
          Affiliated mortgage loans. CitiMortgage will deposit in the certificate
          account on the business day preceding each distribution day the aggregate
          prepayment interest shortfall on the affiliated mortgage loans for
          the

        
          
             

          

          
            65

            
              

            

          

          
             

          

        

        preceding
          month provided that such deposit need not exceed the lesser
          of

        ·      the
          aggregate amount of the collected servicing fees on the affiliated mortgage
          loans for the month preceding such distribution day and

        ·      one-half
          the scheduled servicing fee on the affiliated mortgage loans for that
          month.

        Such
          deposit will not be considered to be a voluntary advance by CitiMortgage,
          and
          will not be reimbursable to CitiMortgage from the certificate account or
          otherwise.

        (b)
          Third-party mortgage loans. Each third-party servicer will transfer to
          the certificate account on each determination date the aggregate amount
          required
          under the Guide to be paid by third-party servicers in respect of prepayment
          interest shortfalls on third-party mortgage loans for the preceding
          month.

        (c)
          Each
          third-party servicer will deposit in the certificate account on the business
          day
          preceding each distribution day the aggregate prepayment interest shortfall
          on
          its third-party mortgage loans for the preceding month, provided that
          the aggregate of such deposits for all third-party loans for any distribution
          day will be reduced by any amounts paid by the third-party servicer under
          the
          preceding paragraph (b) on the preceding determination date.

         

        3.5
          Advances

        (a)
          Servicing account advances. CitiMortgage will deposit in the servicing
          account the payment of property taxes, primary mortgage and hazard insurance
          premiums, and other similar payments that are not timely paid by the mortgagors
          or advanced by the third-party servicers on the date when the tax, premium
          or
          other cost for which the payment is intended is due.

        (b)
          Remittance delinquencies. For each distribution day, a remittance
          delinquency:

        ·      on
          an affiliated loan is the originally scheduled interest at the pass-through
          rate, and principal installment (as adjusted for any principal prepayments),
          on
          the mortgage loan due from the mortgagor on (but not before) the first
          day of
          the month but not received in the certificate account by close of business
          on
          the third business day before the distribution day.

        ·      on
          a third-party loan is the originally scheduled interest at the pass-through
          rate, and principal installment (as adjusted for any principal prepayments),
          on
          the mortgage loan due from the mortgagor on (but not before) the first
          day of
          the month but not received in the certificate account by close of business
          on
          the determination date for the distribution day.

        ·      on
          a buydown mortgage loan is the accrued and unpaid interest at the related
          pass-through rate, and the principal installment (as adjusted for any principal
          prepayments) on the mortgage loan due from the related buydown account
          on (but
          not before) the first day of the month but not received in the certificate
          account by close of business on (a) the third business day before the
          distribution day (for a buydown mortgage loan that is an affiliated loan)
          or
          (b) the determination date (for a buydown mortgage loan that is a
          third-party mortgage loan).

        A
          remittance delinquency does not include

        ·      a
          reduction in principal or interest payments received from a mortgagor due
          to a
          mortgage loan modification pursuant to section 3.19, or

        ·      an
          apparent remittance delinquency that is determined by CitiMortgage to be
          the
          result of the occurrence of an extraordinary event (but not including
          a

        
          
             

          

          
            66

            
              

            

          

          
             

          

        

        remittance
          delinquency determined to be eligible for an advance pursuant to this section
          3.5).

        (c)
          Advances by third-party servicers. To the extent required by its
          third-party servicing agreement, each third-party servicer will transfer
          to the
          certificate account, on the determination date, any amount required to
          be
          advanced under its third-party servicing agreement (a third-party servicer
          advance).

        (d)
          Uncommitted cash advances. On the business day before each distribution
          day, CitiMortgage will transfer from the certificate account to the distribution
          account

        ·      uncommitted
          cash related to affiliated mortgage loans in an amount not greater than
          the
          remittance delinquencies on the affiliated mortgage loans for that distribution
          day, and

        ·      uncommitted
          cash relating to third-party mortgage loans in an amount not greater than
          the
          remittance delinquencies on the third-party mortgage loans for that distribution
          day.

        (e)
          Voluntary advances by CitiMortgage. On the business day before each
          distribution day, CitiMortgage will deposit in the certificate account
          a
voluntary advance equal to

        ·      the
          sum of (i) remittance delinquencies on the mortgage loans for that
          distribution day, (ii) scheduled interest not required to be paid by the
          mortgagors on the first day of the month because of the limitations on
          mortgage
          interest payments under the federal Servicemembers Civil Relief Act or
          any
          comparable state laws, in each case after adjustment of delinquent or

        CitiMortgage
          will on the business day it receives notice from the Paying Agent of the
          amount
          of any affiliated or third-party Paying Agent advance,

        
          	
                  ·

                	
                  pay
                    the Paying Agent a servicing administration fee of $100 for each
                    distribution day on which the Paying Agent makes such an advance,
                    and

                

        

        
          	
                  ·

                	
                  reimburse
                    the Paying Agent for the amount of the
                    advance,

                

        

        provided
          that if the notice is received after 1PM on a business day, the administration
          fee and reimbursement will be made to the Paying Agent by 1PM on the following
          business day.

        Promptly
          after the Trust Fund is terminated pursuant to section 9, CitiMortgage
          will
          notify the Paying Agent of the amount of affiliated and third-party Paying
          Agent
          advances for which CitiMortgage reimbursed the Paying Agent and that were
          not
          recovered from later remittances, net recoveries or other proceeds or
          collections on the affiliated or third-party mortgage loans, respectively.
          The
          Paying Agent will reimburse CitiMortgage for the amount of reimbursements
          not so
          recovered on the next business day after its receipt of the notice.

        (g)
          Limited obligation to make advances. Notwithstanding anything to the
          contrary in this agreement, the relevant servicer will not be obligated
          to make
          any advance described in sections (a) through (e) above, nor will the Paying
          Agent be obligated to make any advance described in section (f) above,
          except to
          the extent that the servicer or the Paying Agent determines that the advance
          will be recoverable from future payments and proceeds on the related mortgage
          loan.

        CitiMortgage
          will provide the Paying Agent with any information CitiMortgage has and
          the
          Paying Agent requests to help the Paying Agent determine if a Paying Agent
          advance will be recoverable.

        (h)
          Future moratorium legislation. If after the date of this agreement, any
          state or locality enacts legislation granting mortgagors a full or partial
          moratorium on mortgage payments while the mortgagor is on active military
          service, CitiMortgage, will, by notice to the Paying Agent, elect whether
          CitiMortgage will advance part or all of any postponed payments under such
          legislation. CitiMortgage will make a separate election for each state
          or
          locality that adopts such legislation. To the extent CitiMortgage elects
          not to
          advance part or all of such postponed payments, the Paying Agent will not
          have
          any obligation to advance such payments.

          reductions thereof without distributions in accordance with this agreement
          (including final distributions under section (c) below or section 9.1)
          will 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 the distributions are noted on the certificate.

        (c)
          Final distributions. If CitiMortgage expects that the principal balance
          of any class will be reduced to zero on the next distribution day, it will,
          not
          later than the third day before that distribution day, mail to the Paying
          Agent
          and each person in whose name a certificate to be so retired is registered

          the close of business on the applicable record date a notice that:

        ·      CitiMortgage
          expects that funds sufficient to reduce the principal balance of the certificate
          to zero will be available in the certificate account on that distribution
          day,
          and

          such funds are available, (A) a final distribution will be made on that
          distribution day, but only upon presentation and surrender of the certificate
          at
          the office or agency of the Paying Agent maintained for that purpose pursuant
          to
          the Series Terms (the address of which will be set forth in the notice),
          and (B)
          no interest will accrue on the certificate after the end of the month preceding
          the distribution day.

        The
          final
          distribution on each certificate (including the final distribution on any
          certificate receiving a distribution in connection with a termination pursuant
          to section 9.1) will be payable only upon presentation and surrender of
          the
          certificate on or after the distribution day for such final distribution
          at the
          office or agency of the Paying Agent maintained for that purpose pursuant
          to the
          Series Terms.

        (d)
          Method of payment. Each distribution will be made

        
          	
                  ·

                	
                  by
                    check mailed to the certificate holder at its address appearing
                    in the
                    Certificate Register, or

                

        

        
          	
                  ·

                	
                  by
                    wire transfer if the certificate holder is eligible for wire
                    transfer
                    under the Series Terms and the Paying Agent has received wiring
                    instructions from the certificate holder,
                    or

                

        

        
          	
                  ·

                	
                  by
                    such other means of payment as the certificate holder, CitiMortgage,
                    and

        Wiring
          instructions received by the Paying Agent will remain in effect until changed
          by
          the certificate holder by written notice to the Paying Agent at least five
          business days before a distribution day.

        (e)
          Unclaimed distributions. Any amounts in the distribution account that
          are distributable as interest or principal pursuant to this section 3.6,
          but are
          not distributed because of the non-presentation of the related certificates,
          or
          because the check for such payment is returned undelivered, will be held
          by the
          Paying Agent for two years in a separate trust account for the benefit
          of the
          holders of such certificates. Amounts in the separate account will be deemed
          to
          have been distributed to the holders for the purpose of any calculations
          required

        
          
             

          

          
            69

            
              

            

          

          
             

          

        

        by
          this
          agreement and will no longer be available for application to any other
          amounts
          due under this agreement.

        After
          two
          years, any amount that remains in the separate account will be paid to
          the
          holders of the residual certificates, as appropriate (except that any amounts
          representing reimbursement for an insured payment will be paid to the Insurer).
          After such payment, the certificate holders will be required to seek payments
          as
          unsecured general creditors from the holders of the residual certificates,
          as
          appropriate.

        (f) Determination
          of distributions. CitiMortgage will determine on each determination date,
          based on payments received on the mortgage loans:

        ·      the
          pool distribution amount;

        ·      the
          interest allocation and interest allocation carryforward for each
          class;

          principal allocation for each class;

        ·      the
          principal distribution for each class;

        ·      any
          ratio-stripped PO class reimbursement;

        ·      any
          insurance premium; and

        ·      any
          other information required to determine the distributions to be made to
          certificate holders in accordance with the Series Terms.

        (g)
          Distribution day data. CitiMortgage will prepare, and will deliver to
          the Paying Agent no later than 12 noon on the third business day before

          portion attributable to the class’s interest allocation
          carryforwards;

        (iv)                  the
          aggregate distribution in reduction of principal balance to be made for

          amount in reduction of principal balance of the certificates that is not
          the
          result of distributions in reduction of principal balance;

        (vi)                  whether
          the amount expected to be available in the certificate account will be
          sufficient to pay all amounts specified in clauses (iii) and (iv) above
          and, if
          not, the percentages of each such amount that may be paid in accordance
          with the
          priorities set forth in the Series Terms from the amounts expected to be
          available in the certificate account;

          amounts included in the statement pursuant to clauses (iii) and (iv) above,

          day;

        (x)        any
          amount to be withdrawn from the certificate account and paid over to the
          holders
          of the class PR or class LR certificates pursuant to section 3.6(h);
          and

        (xi)                  the
          principal balance of the certificates that will remain outstanding after
          giving
          effect to the distributions to be made on the distribution day, expressed
          both
          on an aggregate basis and per $1,000 initial principal balance.

        On
          the
          second business day before each distribution day, CitiMortgage will deliver
          to

        (h)
          Payment of servicing fees; distributions to residual holders. On each
          distribution day, if

        
          	
                  ·

                	
                  CitiMortgage
                    has transferred funds from the certificate account to the distribution
                    account in accordance with section 3.6(a),

                  the
                    Depository for the certificate account has set aside any uncommitted
                    cash
                    in the certificate account that is not required for an uncommitted
                    cash
                    advance, the amount of which uncommitted cash CitiMortgage will
                    certify to
                    such Depository,

          of transfer of or in exchange for or in lieu of any other certificate will
          carry
          the rights to unpaid distributions that were carried by the other
          certificate.

          Third-party servicing

        (a)
          Third-party servicing fee. As compensation for its activities under its
          third-party servicing agreements, each third-party servicer will be entitled
          to
          a third-party servicing fee for each third-party mortgage loan as to which
          a
          monthly installment of principal and interest is received equal to the
          monthly
          third-party servicing fee rate for the mortgage loan multiplied by the
          scheduled
          principal balance on which the installment of interest accrued. (The third-party
          servicer’s compensation may be reduced by any master servicing fee on such
          third-party mortgage loan, as described in the following paragraph
          (b).)

        (b)
          Master servicing fee. CitiMortgage will be entitled to any master
          servicing fee that CitiMortgage and the third-party servicer may agree
          upon in
          the third-party servicing agreement, provided that the master servicing
          fee rate

        ·      for
          a specially serviced mortgage loan may not exceed 0.25% per annum,
          and

        ·      for
          a third-party mortgage loan other than a specially serviced mortgage loan
          may
          not exceed the per annum rate specified as the third-party servicing fee
          rate on
          schedule B-TP to exhibit B under the heading “Sub Fee.”

        CitiMortgage
          may also be entitled to additional master servicing compensation not based
          on
          the master servicing fee rate, as agreed with the third-party servicer,
          such as
          any net REO proceeds in excess of the outstanding principal balance and
          accrued
          interest on a mortgage loan.

        (c)
          CitiMortgage liability. Notwithstanding any third-party servicing
          agreement, provisions of this agreement relating to agreements or arrangements
          between CitiMortgage and a third-party servicer, or reference to actions
          taken
          through a third-party servicer or otherwise, CitiMortgage will remain obligated
          and liable to the Trustee and the certificate holders for the servicing
          of the
          third-party mortgage loans in accordance with this agreement to the same
          extent
          as though CitiMortgage alone were servicing the third-party mortgage loans
          itself.

        
          
             

          

          
            71

            
              

            

          

          
             

          

        

        All
          documents, instruments or contracts executed by third-party servicers on
          behalf
          of CitiMortgage will be treated by the Trustee as though executed by
          CitiMortgage itself.

        Any
          amounts received by a third-party servicer for a third-party mortgage loan will
          be deemed to have been received by CitiMortgage for purposes of this agreement.
          If a third-party servicer fails to remit any amounts it receives that are
          required to be transferred to the certificate account or an escrow account,
          CitiMortgage will transmit the required amounts to the account.

        Nothing
          in this agreement will limit any indemnification agreement between CitiMortgage
          and a third-party servicer, but the indemnification agreement will not
          diminish
          CitiMortgage’s obligations or liability under this agreement.

         

        3.8
          Permitted withdrawals from certificate account

        (a)
          CitiMortgage may pay the following amounts from the certificate account,
          in
          order of priority listed:

        (i)
          to
          itself, collected servicing and master servicing fees (to the extent not
          withheld from payments of interest received on the mortgage loans), and,
          for a
          liquidated loan, the excess of scheduled servicing fees over the collected
          servicing fees;

        
          	
                   

                	
                  (ii)

                	
                  reimbursements
                    to itself for

                

        

        (A) liquidation
          expenses incurred on a mortgage loan, up to the liquidation proceeds on
          the
          mortgage loan deposited in the certificate account, net of applicable servicing
          fees,

        (B) servicing
          advances to the extent not reimbursed under clause (A) and not included
          in
          capitalized reimbursement amounts,

        (C) capitalized
          reimbursement a­mounts, but only to the extent that amounts paid from the
          certificate account prior to any determination date do not exceed principal
          payments deposited in the certificate account on or after the preceding
          distribution date,

        (D) any
          amounts due CitiMortgage under section 3.12 relating to deficiency actions,
          and

        (E) any
          excess of the liquidation proceeds after reimbursement under clauses (A)
          through
          (D) over the principal balance of the mortgage loan, together with accrued
          and
          unpaid interest at the mortgage note rate to the date of purchase at the
          foreclosure sale, liquidation proceeding or otherwise.

        For
          these
          purposes, liquidation expenses will include subsequent trailing bills relating
          to previously disposed reo property in which distribution of net liquidation
          proceeds has occurred.

        (iii)
          reimbursement to itself for (x) voluntary advances or (y) reimbursements by
          CitiMortgage to the Paying Agent for Paying Agent advances. Reimbursements
          pursuant to this clause (iii) will be limited to amounts received on particular
          mortgage loans (including, for this purpose, liquidation and insurance
          proceeds)
          that represent late payments of principal or interest, or subsequent payments
          of
          interest that was excused mortgagors on military service under applicable
          moratorium legislation;

        (iv)
          reimbursement to an advancing person (including CitiMortgage, to the extent
          CitiMortgage has reimbursed the Paying Agent for a Paying Agent advance)
          for
          voluntary or Paying Agent advances that the advancing person determines
          are
          nonrecoverable advances;

        
          
             

          

          
            72

            
              

            

          

          
             

          

        

        (v)
          reimbursement to itself for servicing account advances not previously reimbursed
          out of the servicing account, in each case to the extent that amounts
          representing reimbursements of such advances on mortgage loans may have
          been
          deposited in the certificate account;

        (vi)
          reimbursement to an advancing person of voluntary advances, Paying Agent
          advances, or advance account advances, made on a mortgage loan in an amount
          not
          to exceed at any time in the aggregate the amount of payments from time
          to time
          deposited in the certificate account and not required to be distributed
          to the
          certificate holders (including, for this purpose, liquidation and insurance
          proceeds covering the mortgaged property);

        (vii)
          payments to itself or the holders of the residual certificates of investment
          income;

        (viii)
          transfers to the distribution account;

        (ix)
          payments to clear and terminate the certificate account pursuant to section
          9.1;
          and

        (x)
          all
          remittances received following the repurchase of a mortgage loan that are
          required to be paid to CMSI pursuant to section 2.3.

        CitiMortgage
          may also withdraw funds from the certificate account, and adjust the pool
          distribution amount for any pool or the amount of scheduled or unscheduled
          principal payments, to appropriately adjust for prior servicing errors,
          including errors in posting, allocation, or distribution, if CitiMortgage
          believes that such withdrawals or adjustments are necessary to effect the
          provisions of this agreement.

        If,
          at
          the request of the Trustee, CitiMortgage delivers an officer’s certificate to
          the Trustee in connection with any such withdrawal or adjustment, the Trustee
          may conclusively rely without investigation on the officer’s certificate as to
          the reasons, amount and conformity to this agreement of the withdrawal
          or
          adjustment.

        CitiMortgage
          will maintain separate accounting records, on a mortgage loan-by-mortgage
          loan
          basis, of withdrawals from the certificate account pursuant to clauses
          (ii),
          (iii), (iv), (vi), (vii), (viii) and (x) of this section; provided that
          such records need not be retained by CitiMortgage for a period longer than
          its
          five most recent fiscal years.

        (b)
          In
          lieu of withdrawing collected or scheduled servicing fees from the certificate
          account pursuant to paragraph (a) above, CitiMortgage may, prior to transferring
          collection on mortgage loans, or liquidation or insurance proceeds, to
          the
          certificate account, withhold and pay to itself out of each payment received
          by
          it on account of interest the appropriate collected servicing fee. Any
          amounts
          that CitiMortgage is required to deposit in the certificate account pursuant
          to
          section 3.4, “Prepayment interest shortfalls,” will be deemed to reduce the
          collected or scheduled servicing fee to which CitiMortgage is entitled
          pursuant
          to this section.

         

        3.9
          Expenses

        (a)
          CitiMortgage expenses. CitiMortgage will pay all expenses incurred
          by it in connection with its servicing and master servicing activities
          under
          this agreement, and will not be entitled to reimbursement therefor except
          as
          expressly provided in this agreement. CitiMortgage will also be liable
          for all
          expenses, liabilities and obligations of the Trust Fund (other than the
          obligation to make principal and interest distributions on the certificates)
          including those set forth in section 8.5,

        
          
             

          

          
            73

            
              

            

          

          
             

          

        

        “Trustee’s
          fees and expenses.” To the extent such expenses, liabilities or obligations
          consist of federal income taxes, including, without limitation, prohibited
          transaction taxes, taxes on net income from foreclosure property and taxes
          on
          certain contributions to a REMIC after the startup day, nothing will prevent
          CitiMortgage from contesting any such tax, if permitted by law, pending
          the
          outcome of such proceedings.

        (d)
          Third-party servicer expenses. Each third-party servicer will pay all
          expenses incurred by it in connection with its servicing activities under
          its
          third-party servicing agreement (including advance payment of premiums
          for
          primary mortgage insurance policies, if required) and will not be entitled
          to
          reimbursement therefor except as expressly provided in its third-party
          servicing
          agreement.

         

        3.10
          Primary mortgage insurance 

        CitiMortgage
          will exercise its best reasonable efforts to maintain each primary mortgage
          insurance policy in full force. CitiMortgage will present claims to the
          insurer,
          and take any other reasonable action that may be necessary to permit recovery,
          under any primary mortgage insurance policy for a defaulted mortgage
          loan.

        CitiMortgage
          may substitute for any primary mortgage insurance policy another substantially
          equivalent policy issued by another insurer, provided that no such
          substitution will be made unless (i) CitiMortgage is advised by each rating
          agency that the substitution will not negatively affect the rating agency’s
          then-current rating of any class of certificates (for any insured class
          certificates, without regard to any certificate insurance policy) or (ii)
          the
          claims-paying ability of the substitute primary mortgage insurer is, at
          the time
          of substitution, rated at least AA or its equivalent by each rating agency
          rating the certificates.

         

        3.11
          Hazard insurance

        CitiMortgage
          will maintain for each mortgage loan (other than a mortgage loan for a
          cooperative apartment) hazard insurance with extended coverage in an amount
          at
          least equal to the lesser of

        ·      the
          maximum insurable value of the improvements securing the mortgage loan
          if that
          amount is less than the unpaid principal balance on the mortgage
          loan,

        ·      the
          principal balance owing on the mortgage loan if that amount is between
          80% and
          100%, inclusive, of the insurable value, or

        ·      80%
          of the insurable value if the principal balance of the mortgage loan is
          less
          than 80% of the insurable value.

        Except
          for cooperative apartments, CitiMortgage will also maintain on property
          acquired
          upon foreclosure, or by deed in lieu of foreclosure, hazard fire insurance
          with
          extended coverage in an amount at least equal to the lesser of

        ·      the
          maximum insurable value from time to time of the improvements that are
          a part of
          the property, or

        ·      the
          unpaid principal balance of the mortgage loan at the time of foreclosure
          or deed
          in lieu of foreclosure plus (A) accrued interest at the mortgage note rate
          and
          (B) CitiMortgage’s good-faith estimate of liquidation expenses for the
          property.

        If
          a
          mortgaged property is located in a federally designated flood area, the
          hazard
          insurance will include flood insurance. No earthquake or other additional
          insurance will be required for any property, except as required by applicable
          law.

        
          
             

          

          
            74

            
              

            

          

          
             

          

        

        CitiMortgage
          may maintain a blanket hazard insurance policy on all of the mortgage loans.
          However, if the blanket policy contains a deductible clause, CitiMortgage
          will
          deposit in the certificate account any amount not payable under the blanket
          policy because of the deductible clause that would have been paid under
          a hazard
          policy that meets the requirements of this section and does not have a
          deductible clause.

        Any
          cost
          incurred by CitiMortgage in maintaining hazard insurance will not, for
          the
          purpose of calculating monthly distributions to the certificate holders,
          be
          added to the amount owing under the related mortgage loan, even if the
          terms of
          the mortgage loan permit it.

         

        3.12
          Realization on defaulted mortgage loans

        CitiMortgage
          will use its best efforts, consistent with its customary servicing procedures,
          to foreclose upon or otherwise comparably convert the ownership of properties
          securing any mortgage loans that continue in default and as to which no
          satisfactory arrangements can be made for collection of delinquent payments
          pursuant to section 3.2. Consistent with the foregoing, CitiMortgage will
          use
          reasonable efforts to realize upon defaulted mortgage loans in a manner
          that
          will maximize the receipt of principal and interest by the certificate
          holders,
          taking into account, among other things, the timing of foreclosure
          proceedings.

        If
          a
          deficiency action is available against the mortgagor or any other person,
          CitiMortgage may proceed for the deficiency. CitiMortgage may retain 25%
          of the
          net proceeds received from a mortgagor pursuant to a deficiency action
          as
          compensation for proceeding with the deficiency action.

        Any
          property (other than the mortgaged property) pledged by or on behalf of
          a
          mortgagor as security for a mortgage loan in default, including marketable
          securities, may be liquidated and the proceeds thereof applied to cover
          any
          shortfalls upon the liquidation of a mortgaged property provided that
          the Trust Fund will in no event acquire ownership of any such property
          unless
          the Trustee receives an opinion of counsel to the effect that such ownership
          will not cause any constituent REMIC to fail to qualify as a REMIC and
          will not
          subject any constituent REMIC to any tax.

        If
          title
          to a mortgaged property is acquired in foreclosure or by deed in lieu of
          foreclosure, the deed or certificate of sale will be issued to the Trustee,
          or
          to its nominee on behalf of the Trust Fund. Notwithstanding such acquisition
          of
          title and cancellation of the mortgage loan, the mortgage loan will (except
          for
          purposes of section 9.1) be considered an outstanding mortgage loan until
          the
          mortgaged property is sold and the mortgage loan becomes a liquidated loan.
          Consistent with the foregoing for purposes of all calculations hereunder
          so long
          as the mortgage loan is considered outstanding, it will be assumed that
          the
          related mortgage note and its amortization schedule in effect on and after
          the
          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
          evidenced by the mortgage note will have been discharged), subject to adjustment
          to reflect the application of REO proceeds received in any
          month.

        
          
             

          

          
            75

            
              

            

          

          
             

          

        

        Net
          REO
          proceeds received in any month will 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 loan, with any excess being deemed to have
          been
          received for delinquent principal installments that remained unpaid on
          such
          date. Thereafter, net REO proceeds received in any month will be applied
          to the
          payment of installments of principal and accrued interest on the mortgage
          loan
          deemed to be due and payable in accordance with the terms of the mortgage
          note
          and amortization schedule. If the net REO proceeds exceed the then delinquent
          principal and interest installments on the mortgage loan, the excess will
          be
          treated as a principal prepayment received on the mortgage loan, up to
          the
          outstanding principal balance of the mortgage loan. Any net REO proceeds
          in
          excess of the outstanding principal balance and accrued interest on the
          mortgage
          loan will be treated as additional servicing compensation for
          CitiMortgage.

        If
          CitiMortgage forecloses or accepts a deed in lieu of foreclosure on a mortgaged
          property, CitiMortgage will dispose of the mortgaged property before the
          end of
          the third calendar year that begins after the year of acquisition by the
          applicable constituent REMIC, unless

        ·      (i) the
          Trustee receives an opinion of counsel to the effect that the holding by
          the
          applicable constituent REMIC of the mortgaged property subsequent to such
          period
          (and specifying the period beyond such period for which the mortgaged property
          may be held) will not result in the imposition of taxes on “prohibited
          transactions” of any of the constituent REMICs as defined in Internal Revenue
          Code Section 860F, or cause any of the constituent REMICs to fail to qualify
          as
          a REMIC at any time that any certificates are outstanding, in which case
          the
          applicable constituent REMIC may continue to hold such mortgaged property
          (subject to any conditions contained in such opinion of counsel),
          or

        ·      CitiMortgage
          has, prior to the expiration of such period, applied to the Internal Revenue
          Service for an extension of the period in the manner contemplated by Internal
          Revenue Code Section 856(e)(3), in which case the period will 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 applicable
          constituent REMIC will be

        ·      rented
          (or allowed to continue to be rented) or otherwise used for the production
          of
          income by or on behalf of the applicable constituent REMIC in such a manner
          or
          pursuant to any terms that would (1) cause such mortgaged property to fall
          to
          qualify as “foreclosure property” within the meaning of Internal Revenue Code
          Section 860G(a)(8), (2) subject any of the constituent REMICs 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 Internal Revenue
          Code
          Section 860G(c), or (3) cause the sale of such mortgaged property to result
          in
          the receipt by any of the constituent REMICs of any income from non-permitted
          assets as described in Internal Revenue Code Section 860F(a)(2)(B),
          or

        ·      sold
          in a manner or pursuant to terms that would subject any of the constituent
          REMICs to the imposition of any federal or state income taxes on “net income
          from foreclosure property” within the meaning of Internal Revenue Code Section
          860G(c), unless CitiMortgage

        
          
             

          

          
            76

            
              

            

          

          
             

          

        

        agrees
          to
          indemnify and hold harmless each constituent REMIC against the imposition
          of
          such taxes.

        The
          foregoing is subject to the provision that, if any mortgaged property is
          damaged, whether from an uninsured cause or otherwise, CitiMortgage will
          not be
          required to expend its own funds in connection with any foreclosure or
          towards
          the restoration of such property unless it determines that

        ·      the
          restoration or foreclosure will increase the net proceeds of liquidation
          of the
          mortgage loan to the certificate holders, after reimbursement to itself
          for such
          expenses, and

        ·      CitiMortgage
          will recover such expenses through liquidation or insurance
          proceeds.

        CitiMortgage
          will be responsible for all other costs and expenses incurred by it in
          any such
          proceedings; provided, however, that it will be entitled to
          reimbursement thereof from the related property, as contemplated in section
          3.8.
          Notwithstanding the above, CitiMortgage will not be entitled to recover
          legal
          expenses incurred in connection with liquidation proceedings where the
          mortgagor
          pays all delinquent payments and expenses and the proceedings are terminated
          prior to liquidation, other than sums received from the mortgagor for such
          expenses.

        Notwithstanding
          anything to the contrary in this section 3.12, CitiMortgage will not be
          obligated to foreclose upon or otherwise convert the ownership of any mortgaged
          property that it believes may be contaminated with or affected by pollutants,
          contamination, hazardous wastes or hazardous substances. CitiMortgage will
          not
          be liable to the certificate holders if, based on its belief that no such
          contamination or effect exists, CitiMortgage forecloses on a mortgaged
          property
          and takes title to such mortgaged property, and the mortgaged property
          is later
          determined to be so contaminated or affected.

        If
          CitiMortgage does not elect to foreclose on a mortgaged property, CitiMortgage
          may, in the exercise of its judgment, elect to accept a payment or payments,
          in
          connection with the sale by the mortgagor of the mortgaged property or
          the
          retention by the mortgagor of the mortgaged property, in aggregate amount
          less
          than the outstanding balance of the mortgage loan and accrued interest
          thereon.

        The
          Trustee will furnish CitiMortgage with any powers of attorney and other
          documents necessary or appropriate to enable CitiMortgage to carry out
          its
          efforts in realizing upon defaulted mortgage loans hereunder.

         

        3.13
          Release of mortgage files 

        (a)
          CitiMortgage will promptly notify the Trustee of the payment in full of
          any
          mortgage loan or CitiMortgage’s receipt of notice that payment in full will be
          escrowed in a manner customary for such purpose, and will request delivery
          to it
          of the mortgage file. CitiMortgage’s notice will include a Servicing Officer
          certification that all amounts that CitiMortgage must deposit in the certificate
          account, in connection with the payment pursuant to section 3.3 have been
          or
          will be so deposited. Upon receipt of the certification and request, the
          Trustee
          will promptly direct the Mortgage Note Custodian to release the related
          mortgage
          note to CitiMortgage.

        For
          the
          servicing or foreclosure of any mortgage loan, including collection under
          a
          primary mortgage insurance policy, the Trustee will, upon CitiMortgage’s request
          and its delivery to the Trustee of a receipt signed by a

        
          
             

          

          
            77

            
              

            

          

          
             

          

        

        Servicing
          Officer, direct the Mortgage Note Custodian to release the related mortgage
          note
          to CitiMortgage. The Trustee will execute such documents furnished it as
          are
          necessary to the prosecution of any such proceedings. The receipt will
          obligate
          CitiMortgage to return the mortgage note to the Mortgage Note Custodian
          when
          CitiMortgage no longer needs it, unless the mortgage loan has been prepaid
          or
          liquidated in the interim, in which case, upon receipt of a Servicing Officer
          certification similar to that described in the first paragraph of this
          section,
          the Trustee will release the receipt to CitiMortgage.

        (b)
          CitiMortgage will record any instrument of satisfaction of the mortgage
          executed
          by it if required by applicable law, and deliver it to the person entitled
          thereto. CitiMortgage may not withdraw any expenses incurred in connection
          with
          the instrument of satisfaction from the certificate account.

          prepare

        
          
             

          

          
            80

            
              

            

          

          
             

          

        

        the
          foregoing returns, schedules, statements or information.

        (e)
          Each
          holder of a residual certificate will be deemed to have agreed, by acceptance
          thereof, to be bound by this section 3.15 and by section 5.2 and by “REMIC
          Provisions” in the Series Terms.

         

        3.16
          Application of buydown funds 

        On
          or
          before the closing date if there are any buydown mortgage loans in the
          Trust
          Fund, CitiMortgage will open the buydown account with the Depository in
          the name
          of the Trustee, on behalf of the mortgagors. For each buydown mortgage
          loan, on
          the business day following receipt of the mortgagor’s required monthly payment
          under the buydown agreement, CitiMortgage will withdraw from the buydown
          account
          and deposit in immediately available funds in the certificate account an
          amount
          which, when added to the mortgagor’s payment, will equal the full monthly
          payment due under the mortgage note. No later than the fifth business day
          before
          the last business day of each month, CitiMortgage will deposit 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 for each buydown mortgage loan.

        If
          a
          buydown mortgage loan is fully prepaid while buydown funds remain in the
          buydown
          account, the unpaid principal balance of the buydown mortgage loan will
          be
          reduced by the amount of the buydown funds (which reduction will constitute
          a
          principal prepayment) and, on the business day following the date of the
          principal prepayment, CitiMortgage will deposit the buydown funds in the
          certificate account. If the property securing a buydown mortgage loan is
          sold in
          liquidation of the buydown mortgage loan (either by CitiMortgage or the
          insurer
          under any related primary mortgage insurance policy) while buydown funds
          remain
          in the buydown account, the buydown funds will be (i) deposited in the
          certificate account on the business day following the liquidation as a
          reduction
          of the unpaid principal balance of the buydown mortgage loan or (ii) to
          the
          extent required under an applicable primary mortgage insurance policy,
          paid to
          the insurer of the mortgage loan.

         

        3.17
          Assumption and modification agreements 

        If
          a
          mortgagor transfers a mortgaged property that is subject to an enforceable
          due-on-sale clause, CitiMortgage will accelerate the maturity of the mortgage
          loan to the extent permissible, unless CitiMortgage reasonably believes
          that the
          due-on-sale clause is not enforceable.

        If
          CitiMortgage reasonably believes that the mortgaged property is not subject
          to
          an enforceable due-on-sale clause, or that enforcement will adversely affect
          primary mortgage insurance coverage, CitiMortgage may enter into an assumption
          and modification agreement with the transferee of the mortgaged property,
          pursuant to which both the transferee and the original mortgagor will be
          liable
          on the mortgage loan, provided that

        ·      the
          mortgage loan as assumed or modified meets the requirements set forth in
          this
          agreement for mortgage loans initially included in the Trust Fund,

        ·      the
          mortgage loan continues to be covered by any related primary mortgage insurance
          and hazard insurance policy, and

        
          
             

          

          
            81

            
              

            

          

          
             

          

        

        ·      no
          principal, interest or other payment on the mortgage loan is reduced or
          postponed.

        CitiMortgage
          will add an original of each assumption and modification agreement to the
          related mortgage file (and will send a copy to the Trustee), and the agreement
          will be considered a part of the mortgage file for all purposes to the
          same
          extent as all other documents and instruments that are part of the mortgage
          file. Any fee collected by CitiMortgage for entering into such an agreement
          will
          be retained by CitiMortgage as additional servicing compensation.

         

        3.18
          Refinancings and curtailments

        In
          addition to waivers and arrangements permitted by section 3.2, CitiMortgage
          may
          refinance affiliated or third-party mortgage loans if the refinancing arises
          out
          of a mortgagor’s request for a refinancing, modification, or other relief from
          the provisions of the mortgage loan.

        On
          the
          business day preceding the distribution day in the month following the
          effective
          date of the refinancing of a mortgage loan pursuant to this section,
          CitiMortgage will deposit into the certificate account the amount of the
          prepayment in full of the mortgage loan (net of all voluntary advances
          and
          Paying Agent advances for the mortgage loan, which will be reimbursed to
          the
          Paying Agent or deemed reimbursed to CitiMortgage, as the case may be).
          Upon the
          Trustee’s receipt of written notification of the deposit signed by an Authorized
          Officer of CitiMortgage, the Trustee will promptly direct the Mortgage
          Note
          Custodian to release the related mortgage note to CitiMortgage, and the
          Trustee
          will comply with the provisions of section 3.13.

        For
          the
          purposes of this section, a “refinancing” will include any process with a
          mortgagor that results in the refinanced mortgage loan being identified
          and
          serviced as a “new mortgage loan” in CitiMortgage’s books, records and servicing
          files. However, in connection with a partial prepayment, CitiMortgage may
          reduce
          the scheduled monthly payments on the mortgage loan so that the mortgage
          loan
          will still be paid in equal monthly installments of principal and interest,
          but
          the prepayment will not change the originally scheduled maturity date,
          and such
          modification will not be considered a “refinancing” for purposes of this
          section.

         

        3.19
          Loan modifications

        (a) CitiMortgage
          may agree with any mortgagor to modify or waive any provision of a mortgage
          loan
          if the modification or waiver does not

        ·      affect
          the amount or timing of any payment of principal or interest on the mortgage
          loan,

        ·      in
          CitiMortgage’s judgment, materially impair the security for, or reduce the
          likelihood of timely payment of amounts due on, the mortgage loan,
          or

        ·      otherwise
          constitute a “significant modification” within the meaning of Treasury
          Regulations Section 1.860G-2(b).

        (b) Notwithstanding
          the preceding section (a), CitiMortgage may agree with any mortgagor to
          modify
          or waive any provision of a mortgage loan if

        ·      the
          mortgage loan is in default or, in CitiMortgage’s judgment, default is
          reasonably foreseeable, or

        ·      CitiMortgage
          delivers to the Trustee an opinion of counsel to the effect that the
          modification or waiver will not affect the REMIC status of any
          REMIC.

        A
          loan
          modification may

        
          
             

          

          
            82

            
              

            

          

          
             

          

        

        ·      extend
          the maturity of the mortgage loan, but not beyond the last scheduled
          distribution day for the certificates related to the pool containing the
          mortgage loan,

        ·      postpone
          any payment of principal or interest,

        ·      reduce
          the outstanding principal balance of the mortgage loan, including forgiving
          all
          or part of previously scheduled principal payments not made by the
          mortgagor,

        ·      reduce
          the interest payable on the mortgage loan, including forgiving all or part
          of
          previously scheduled interest payments not made by the mortgagor,
          or

        ·      increase
          the principal balance of the mortgage loan by part or all of the amount
          of any
          unreimbursed servicing advances (such increase being a capitalized
          reimbursement amount).

        If
          a
          mortgage loan is modified by reduction of the principal balance of the
          mortgage
          loan, the amount of the reduction will be a realized loss, allocated between
          the
          target rate and PO strips in the same percentage as the loan was allocated
          immediately prior to the modification; if voluntary advances were made
          on the
          mortgage loan to the full amount of scheduled monthly loan payments, the
          realized loss will be the difference between the principal balance of the
          modified mortgage loan and the scheduled principal balance of the mortgage
          loan
          before modification.

        (c) CitiMortgage
          may not agree with a mortgagor to modify or waive a provision of a mortgage
          loan
          under the preceding section (b) unless CitiMortgage reasonably determines
          that
          the mortgagor can make scheduled monthly loan payments on the modified
          loan, and
          the modification

        ·      is
          in the best interests of the certificate holders in the aggregate without
          regard
          to the specific impact on any particular class,

        ·      is
          neutral as to the effect on interest or principal distributions for any
          particular class, taking into account the net present value of payments
          on the
          modified mortgage loan and estimated realized losses that might result
          if the
          mortgage loan is not modified, and

        ·      does
          not result in taxes on any REMIC, or impair the tax status of any
          REMIC.

        (d) CitiMortgage
          will within 10 business days deposit in the related mortgage file an original
          signed copy of the agreement providing for the modification or waiver.
          If
          applicable law requires a modification or waiver to be recorded, CitiMortgage
          will (i) deliver a copy of such signed agreement to the Trustee and
          (ii) deliver to the Trustee such document, with evidence of notification
          upon receipt thereof from the public recording office.

        CitiMortgage
          may condition any modification or waiver on the mortgagor’s payment to
          CitiMortgage of a reasonable or customary fee for the additional services
          performed, together with reimbursement for CitiMortgage’s out-of-pocket
          expenses, in connection with the modification or waiver. CitiMortgage may
          retain
          such fees or reimbursements as additional servicing compensation.

        (e) This
          section 3.19 may not be amended unless each rating agency confirms in writing
          to
          CitiMortgage (with a copy to the Trustee) that the amendment will not adversely
          affect the rating agency’s then-current rating of any class of
          certificates.

         

        3.20
          Investment accounts

        (a)
          Investments. CitiMortgage may invest and reinvest funds in an
          investment

        
          
             

          

          
            83

            
              

            

          

          
             

          

        

        account
          in accordance with this section 3.20 in one or more Eligible Investments
          (as
          described below) bearing interest or sold at discount. However, no such
          investment may mature later than the business day immediately preceding
          the next
          distribution day, except, that investments (including repurchase
          agreements) on which the Paying Agent, in its commercial capacity, is the
          obligor may mature on the next distribution day.

        The
          Trustee and CitiMortgage will deposit in the certificate account immediately
          upon receipt all proceeds from investment of funds and disposition of assets
          in
          the certificate account. Any loss resulting from such investment will be
          charged
          to the certificate account.

        CitiMortgage
          may withdraw investment income from any investment account and pay such
          income
          to itself, the seller or the holders of the residual certificates, as
          applicable.

        CitiMortgage
          will not invest funds in the certificate account or sell an investment
          held in
          an investment account unless the investment:

        ·      is
          made in the name of the Trustee (in its capacity as such) or a Qualified
          Nominee
          of the Trustee, and

        ·      is
          a “cash flow investment” as defined in Internal Revenue Code Section
          860G(a)(6).

        CitiMortgage
          will not dispose of any Eligible Investment prior to its maturity. However,
          if
          sufficient uninvested funds are not available in the certificate
          account to make a required disbursement, CitiMortgage may sell or otherwise
          convert to cash a sufficient amount of the investments in the certificate
          account if, prior to such sale or conversion, CitiMortgage receives

        (i)
          an
          opinion of counsel (which opinion may not be provided by an employee of
          CitiMortgage or of an affiliate of CitiMortgage) that the sale or conversion
          will not constitute a “prohibited transaction” under Internal Revenue Code
          Section 860F(a), or

        (ii)
          if
          the sale or conversion constitutes such a “prohibited transaction,” (A) 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 the transaction,
          and
          (B) an opinion of counsel (which opinion may not be provided by an employee
          of
          CitiMortgage or of an affiliate of CitiMortgage) that the transaction will
          not
          disqualify any constituent REMIC as a REMIC.

        The
          Trustee will not have any liability for any loss incurred in connection
          with any
          investment or any sale or liquidation thereof pursuant to this agreement,
          unless
          caused by its negligence or willful misconduct, or for any insufficiency
          in the
          certificate account or the buydown account, except for losses on investments
          that are liabilities of the Trustee in its commercial capacity.

        (b)        Custodial
          investment account. Prior to the business day preceding the distribution
          day, CitiMortgage may deposit the amounts required to be transferred on
          the
          determination date from the custodial accounts for P&I in a separate account
          in the name of CitiMortgage and the Trustee (such account will be maintained
          in
          the trust department of a Depository and will 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 certificate holders) (the custodial
          investment account) for investment only in one or more Eligible
          Investments. CitiMortgage will bear any and all losses incurred on
          any

        
          
             

          

          
            84

            
              

            

          

          
             

          

        

        investments
          made with such funds and will 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 will be
          deposited in the custodial investment account by CitiMortgage out of its
          own
          funds immediately as realized. Any successor master servicer appointed
          pursuant
          to this agreement will not be responsible for losses attributable to its
          predecessor. No investments held in the custodial investment account will
          mature
          later than the business day preceding the distribution day.

        (c)
          Eligible Investments. Eligible Investments means any one or
          more of the following obligations or securities:

        (i)          direct
          obligations of, and obligations fully guaranteed by, the United States
          of
          America, Freddie Mac, Fannie Mae, the Farm Credit Banks, the Federal Home
          Loan
          Banks, the Student Loan Marketing Association (but only for obligations
          backed
          by letters of credit or senior obligations) or any agency or instrumentality
          of
          the United States of America the obligations of which are backed by the
          full
          faith and credit of the United States of America; provided, however, that
          any
          obligation of, or guaranteed by, the Federal Home Loan Banks or the Farm
          Credit
          Banks or any obligation of, or guaranteed by, Freddie Mac or Fannie Mae,
          other
          than a senior debt obligation of Freddie Mac or Fannie Mae or a mortgage
          participation or pass-through certificate guaranteed by Freddie Mac or
          Fannie
          Mae, excluding stripped mortgage securities which are valued greater than
          par on
          the portion of unpaid principal, will be an Eligible Investment only if,
          at the
          time of investment, each rating agency confirms in writing that such investment
          is acceptable;

        (ii)          Federal
          Funds, demand and time deposits in, certificates of deposits of, or bankers’
acceptances issued by, any depository institution or trust company (including
          the Trustee or any agent of the Trustee, acting in their respective commercial
          capacities) incorporated under the laws of the United States of America
          or any
          state thereof and subject to supervision and examination by federal or
          state
          banking authorities, so long as at the time of such investment or contractual
          commitment providing for such investment the certificate of deposit or
          other
          unsecured short-term debt obligations of such depository institution or
          trust
          company have a maturity of not more than one year and a credit rating of

          such

          Certificate Registrar and the Trustee and any agent of the Trustee that
          such
          certificate holder is duly authorized by and empowered under appropriate
          governing instruments (for example, an employee benefit plan, in the case
          of an

          do
          not exceed 20% of the then scheduled principal balance of the mortgage
          loans) if
          S&P is a rating agency, F1 if Fitch is a rating agency, and P-1 if Moody’s
          is a rating agency, or if such investment relates to a money
          market

        3.21
          Paying Agent and Certificate Registrar

        (a)
          Paying Agent. CitiMortgage or the Trustee may remove a Paying Agent,
          and CitiMortgage, with the Trustee’s approval, may appoint another Paying Agent.
          Any Paying Agent must, and CitiMortgage will remove any Paying Agent that
          at any
          time fails to, satisfy the criteria in the following paragraph.

        A
          Paying
          Agent

        ·      may
          not be an Originator, CitiMortgage or an affiliate of CitiMortgage unless
          the
          Paying Agent is an agency and trust department of Citibank, N.A.,

        ·      must
          be authorized to exercise corporate trust powers under the laws of its
          jurisdiction of organization, and

        ·      must
          be rated at least A-1 by S&P if S&P is a rating agency, and at least F1
          by Fitch if Fitch is a rating agency.

        If
          no
          Paying Agent is appointed, the Trustee will be the Paying Agent. CitiMortgage
          will notify the rating agencies of any change of Paying Agent.

        The
          Paying Agent will

        ·      hold
          all amounts deposited with it by CitiMortgage or the Trustee for payment
          on the
          certificates in trust for the benefit of the certificate holders and any
          Insurer
          until the amounts are paid to the certificate holders or the Insurer or
          otherwise disposed of in accordance with this agreement,

        ·      give
          the Trustee notice of any default by CitiMortgage in making any such deposit,
          and

        ·      during
          the continuance of a default by CitiMortgage in making such a deposit,
          upon the
          Trustee’s written request, immediately pay to the Trustee all amounts so held in
          trust by the Paying Agent.

        CitiMortgage
          will cause any Paying Agent that is not the Trustee or a signatory to this
          agreement to execute and deliver to the Trustee an instrument in which
          the
          Paying Agent agrees with the Trustee that the Paying Agent will have all
          the
          rights and obligations of a Paying Agent under this agreement.

        (b)
          Certificate Registrar. CitiMortgage or the Trustee may remove a
          Certificate Registrar, and CitiMortgage, with the Trustee’s approval, may
          appoint another Certificate Registrar.

        A
          Certificate Registrar

        ·      may
          not be an Originator, CitiMortgage or an affiliate of CitiMortgage unless
          the
          Certificate Registrar is an agency and trust department of Citibank, N.A.,
          and

        ·      must
          be authorized to exercise corporate trust powers under the laws of its
          jurisdiction of organization.

        If
          no
          Certificate Registrar is appointed, the Trustee will be the Certificate
          Registrar.

         

        3.22
          Exchange Act reporting

        (a)
          CitiMortgage, as servicer, will prepare and file all reports required to
          be
          filed by CMSI, as depositor, under the Exchange Act (other than Forms 10-K),
          including required periodic reports on Form 10-D, and any required current
          report on Form 8-K. CMSI authorizes CitiMortgage to

        
          
             

          

          
            87

            
              

            

          

          
             

          

        

        sign
          and
          file such reports on behalf of CMSI. CMSI will file all required Forms
          10-K.

        (b)
          For
          each calendar year for which CMSI is required to file a Form 10-K with
          the
          Securities and Exchange Commission for this series, each party to this
          agreement
          who

        ·      participates
          in the servicing function, within the meaning of section 1122 of Regulation
          AB
          under the Securities Act (Regulation AB), for this series, or who
          controls such a participant, will submit, or will cause such controlled
          participant to submit, by March 1 of the following year, a report on an
          assessment of compliance covering the servicing criteria set forth opposite
          its
          name on schedule 1, “Servicing criteria to be addressed in report on assessment
          of compliance” (as such schedule may be modified pursuant to section 3.22(c)
          below), and an attestation report of a registered public accounting firm,
          all as
          required by and in full conformity with the requirements of rule 1122,
          and

        ·      is
          a servicer, within the meaning of section 1123 of Regulation AB, for this
          series, or who controls such a servicer, will submit, or will cause such
          controlled servicer to submit, by March 1 of the following year, a statement
          of
          compliance signed by an authorized officer, as required and in full conformity
          with the requirements of rule 1123.

        (c)
          Schedule 1 may be modified

        ·      by
          agreement of CMSI and each party affected by such modification, without
          the
          consent of any other party or the certificate holders, and

        ·      by
          CMSI, without the consent of any other party or the certificate holders,
          if CMSI
          is advised by counsel that such change may be required to comply with Regulation
          AB.

        (d)
          CMSI
          and each other person who is or becomes a party to this agreement will
          render
          all reasonably requested assistance to CMSI and CitiMortgage in providing
          information necessary for the preparation of such reports. CMSI and CitiMortgage
          will require each third-party servicer, and any other person who participates
          in
          the servicing function, to agree to provide such assistance.

        (e)
          CitiMortgage hereby appoints KPMG LLP as its independent accountants for
          purposes of preparing and delivering for each year an attestation on
          CitiMortgage’s assessment of compliance with the applicable servicing criteria
          as of and for the period ending the end of such year. The attestation report
          is
          to be furnished to CitiMortgage and the Trustee by March 1 in the following
          year, and must be made in accordance with standards for attestation engagements
          issued or adopted by the Public Company Accounting Oversight Board.

        If
          such
          firm resigns, CitiMortgage will promptly appoint a successor firm of independent
          accountants of recognized national reputation. CitiMortgage will promptly
          notify
          the Trustee if CitiMortgage fails to appoint a successor firm of independent
          accountants within 15 days after such resignation. If CitiMortgage does
          not
          appoint a successor within 10 days thereafter, the Trustee will promptly
          appoint
          a successor firm of independent accountants of recognized national reputation.
          The fees of the independent accountants and any successor will be paid
          by
          CitiMortgage as servicer, or by any successor servicer.

        4.1
          Liability of CitiMortgage and others

        Each
          of
          CitiMortgage, CMSI and Citibank, N.A. will be liable under this agreement
          to any
          person or to the certificate holders only to the extent of obligations
          specifically undertaken by CitiMortgage, CMSI or Citibank, N.A. in this
          agreement.

        Neither
          CitiMortgage, CMSI nor Citibank, N.A., nor any of their directors, officers,
          employees and agents will be liable to the Trust Fund or the certificate
          holders
          for any action, or for refraining from taking any action, pursuant to this
          agreement, or for errors in judgment, provided, however, that neither
          CitiMortgage, CMSI, Citibank, N.A., nor any such person will be protected
          against any liability that would otherwise be imposed for willful misfeasance,
          bad faith or gross negligence in the performance, or for reckless disregard,
          of
          their obligations under this agreement. CitiMortgage, CMSI, Citibank, N.A.
          and
          any of their directors, officers, employees or agents may rely on any document
          prima facie properly executed and submitted by any person as to any
          matters arising under this agreement.

        CitiMortgage,
          CMSI, Citibank, N.A., and each of their directors, officers, employees
          and
          agents will be indemnified and held harmless by the Trust Fund against
          any loss,
          liability or expense incurred in connection with any actual or threatened
          legal
          or regulatory proceedings relating to this agreement or the certificates,
          other
          than a loss, liability or expense incurred by reason of willful misfeasance,
          bad
          faith or gross negligence in the performance, or reckless disregard, of
          their
          obligations under this agreement.

        CitiMortgage
          need not appear in, prosecute or defend any legal action that is not incidental
          to its duties to service the mortgage loans in accordance with this agreement
          and that in its opinion may involve it in any expense or liability. CitiMortgage
          may, however, undertake any such action it deems desirable to enforce or
          secure
          the rights and duties of the parties or the interests of the certificate
          holders. CitiMortgage’s legal expenses and costs of such action and any
          resulting liability will be expenses, costs and liabilities of the Trust
          Fund,
          for which CitiMortgage will be reimbursed out of the certificate
          account.

        Notwithstanding
          the foregoing, CitiMortgage will indemnify, defend and hold harmless the
          Trustee
          and the Trust Fund against any damages, claims or liabilities arising out
          of any
          violation (or claimed violation) prior to the closing date of any predatory
          lending law.

         

        4.2
          Assumption of CitiMortgage’s obligations by affiliate

        Any
          corporation into which CitiMortgage is merged or consolidated, or that
          results
          from a merger, conversion or consolidation involving CitiMortgage, or that
          succeeds to the business of CitiMortgage, or more than 50% of the voting
          stock
          of which is, directly or indirectly, owned by Citigroup Inc., and that
          executes
          an agreement of assumption to perform all of CitiMortgage’s obligations under
          this agreement, will be CitiMortgage’s successor under this agreement, 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. Such
          agreement of assumption will not, however, release CitiMortgage from
          any

        
          
             

          

          
            89

            
              

            

          

          
             

          

        

        of
          its
          obligations or liabilities under this agreement.

         

        4.3
          Maintenance of office or agency

        CMSI
          will
          maintain or cause to be maintained at its expense an office or offices
          or agency
          or agencies where the certificates may be surrendered for registration
          of
          transfer or exchange and where notices and demands to or upon CMSI in respect
          of
          the certificates and this agreement may be served. CMSI initially appoints
          the
          Certificate Registrar designated in the Series Terms as its office for
          purposes
          of receipt of notices and demands. CMSI will give prompt written notice
          to
          CitiMortgage, the Trustee and the certificate holders of any change in
          the
          location of the Certificate Register or any such office or agency.

         

        4.4
          Servicer not to resign

        Subject
          to sections 4.2 and 4.5, CitiMortgage will not resign as servicer without
          the
          consent of the Trustee, any Insurer, the holders of more than 2/3 of the
          voting
          interests of the outstanding certificates and 2/3 of the percentage interests
          of
          the residual certificates, except upon a determination that the performance
          of
          its duties hereunder is no longer permissible under applicable law. Any
          such
          determination permitting the resignation of CitiMortgage as servicer will
          be
          supported by an opinion of counsel to such effect delivered to the Trustee.
          No
          resignation by CitiMortgage will become effective until the Trustee or
          a
          successor servicer and master servicer have assumed CitiMortgage’s obligations
          in accordance with section 7.2.

         

        4.5
          Delegation of duties

        CitiMortgage
          may without notice or consent delegate any of its servicing duties, and
          any
          rights relating to such duties, to any person or persons, including a person
          more than 50% of whose stock is owned, directly or indirectly, by Citigroup
          Inc.; provided that each such person that services any mortgage loans has
          been
          approved as a seller/servicer by the Federal Housing Administration, GNMA,
          Fannie Mae or Freddie Mac, and has been approved in writing by the rating
          agencies. Such delegation will not, however, relieve CitiMortgage of its
          responsibility for such duties. Each delegee of CitiMortgage’s servicing duties
          will have those powers and duties that are granted to or required of
          CitiMortgage as servicer or master servicer under this agreement for such
          duties, subject to the limitations imposed by the agreement between CitiMortgage
          and such delegee.

         

        4.6
          Errors and omissions insurance

        CitiMortgage
          will maintain in force

        ·      a
          policy or policies of insurance covering errors and omissions in the performance
          of its servicing obligations, and

        ·      a
          fidelity bond for its officers, employees and agents.

        Such
          policies and bond will, together, comply with Fannie Mae or Freddie Mac
          requirements for persons servicing mortgage loans purchased by such
          association.

The
          certificates

         

        5.1
          The certificates

        (a)
          The
          certificates and residual certificates will be substantially in the forms
          set
          forth in exhibit A. The certificates will be issued in the denominations
          specified in the Series Terms and will be executed by manual or facsimile
          signature on behalf of CMSI by its Chairman, President, one of its Vice
          Presidents, or one of its Assistant Vice Presidents. Certificates bearing
          the
          manual or facsimile signatures of

        
          
             

          

          
            90

            
              

            

          

          
             

          

        

        individuals
          who were authorized to sign on behalf of CMSI when the signatures were
          affixed
          will bind CMSI, even if prior to the authentication and delivery of the
          certificates some of the individuals ceased to be authorized or to hold
          such
          offices.

        No
          certificate will be entitled to any benefit under this agreement, or be
          valid
          for any purpose, unless it authenticated substantially in the form set
          forth in
          exhibit A. The authentication must be manually signed by the Trustee or
          an
          Authenticating Agent appointed pursuant to section 8.12, and such signature
          will
          be conclusive evidence, and the only evidence, that the certificate has
          been
          duly authenticated and delivered. All certificates will be dated the date
          of
          their authentication.

        (b)        Upon
          original issuance, book-entry certificates will be issued in the form of
          one or
          more typewritten certificates, to be delivered to the initial Clearing
          Agency,
          by, or on behalf of, CMSI. Such certificates will initially be registered
          on the
          Certificate Register in the name of the nominee of the initial Clearing
          Agency,
          and will bear a legend in substantially the following form:

        “Unless
          this certificate is presented by an authorized representative of [the Clearing
          Agency] to Citicorp Mortgage Securities, Inc. or its agent for registration
          of
          transfer, exchange, or payment, and any certificate issued is registered
          in the
          name of [the Clearing Agency nominee] or such other name as requested by
          an
          authorized representative of [the Clearing Agency] (and any payment is
          made to
          [the Clearing Agency nominee] or to such other entity as is requested by
          an
          authorized representative of [the Clearing Agency]), any transfer, pledge,
          or
          other use hereof for value or otherwise by or to any person is wrongful
          inasmuch
          as the registered owner hereof, [the Clearing Agency nominee], has an interest
          herein.”

        No
          beneficial owner will receive a definitive certificate representing such
          beneficial owner’s interest in the book-entry certificates, except as provided
          in section 5.6. Until definitive certificates have been issued to beneficial
          owners pursuant to section 5.6:

        (i)        This
          section 5.1(b) will be in full force and effect.

        (ii)        CMSI,
          the Certificate Registrar and the Trustee may deal with the Clearing Agency
          for
          all purposes (including distributions on the book-entry certificates and
          actions
          by the holders of book-entry certificates) as the authorized representative
          of
          the beneficial owners.

        (iii)                  To
          the extent that this section 5.1(b) conflicts with any other provision
          of this
          agreement, this section 5.1(b) will control.

        (iv)                  The
          rights of beneficial owners will be exercised only through the Clearing
          Agency
          and will be limited to those established by law, the rules, regulations
          and
          procedures of the Clearing Agency and agreements between such beneficial
          owners
          and the Clearing Agency or the Clearing Agency Participants. For book-entry
          certificates, references in this agreement to

        ·      actions
          by certificate holders will refer to actions taken by the Clearing Agency
          upon
          instructions from the Clearing Agency Participants, and

        ·      distributions,
          notices, reports and statements to certificate holders will refer to
          distributions, notices, reports and statements to the Clearing Agency or
          its
          nominee, as registered holder of the book-entry certificates for the
          distribution to beneficial owners in accordance with the procedures of
          the
          Clearing Agency.

        
          
             

          

          
            91

            
              

            

          

          
             

          

        

        (v)        The
          initial Clearing Agency will make book-entry transfers among the Clearing
          Agency
          Participants, and will receive and transmit distributions of principal
          and
          interest on the certificates to the Clearing Agency Participants, for
          distribution to the beneficial owners or their nominees.

        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 will be
          given
          by beneficial owners having the requisite percentage interests.

        Until
          definitive certificates are issued to beneficial owners pursuant to section
          5.6,
          copies of the reports or statements referred to in section 3.14 will be
          available to beneficial owners upon written request to the Trustee at the
          corporate trust office or, if Citibank, N.A. is the Paying Agent, at the
          website
          referred to in section 3.14.

         

        5.2
          Registration of transfer and exchange of certificates

        (a)
          CMSI
          will maintain at its expense an office or offices or agency or agencies
          where
          the certificates may be surrendered for registration of transfer or exchange
          and
          where notices and demands to or upon CMSI relating to the certificates
          and this
          agreement may be served. CMSI initially appoints the Certificate Registrar
          designated in the Series Terms as its office for purposes of receipt of
          notices
          and demands.

        CMSI
          will
          maintain a Certificate Register at such office in which, subject to
          such reasonable regulations as it prescribes, CMSI will provide for the
          registration and transfer of certificates. CMSI will give prompt written
          notice
          to the Trustee and to the certificate holders of any change in the location
          of
          the Certificate Register or any such office or agency.

        Upon
          surrender for registration of transfer of any certificate at the office
          or
          agency, CMSI will execute and the Trustee or the Authenticating Agent will
          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 certificate holder, 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 the office or
          agency.
          CMSI will execute and the Trustee or Authenticating Agent will authenticate
          and
          deliver the certificates that the certificate holder is entitled to
          receive.

        Every
          certificate surrendered for registration of transfer or exchange will be
          accompanied by a written instrument of transfer in form satisfactory to
          the
          Trustee, CMSI and the Certificate Registrar, duly executed by the holder
          or his
          attorney duly authorized in writing.

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

        All
          certificates surrendered for registration of transfer and exchange will
          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.

        
          
             

          

          
            92

            
              

            

          

          
             

          

        

        The
          Certificate Registrar will provide the Paying Agent and the Trustee by
          the third
          business day before each distribution day, the names and addresses of each
          certificate holder as of the record date and the number of single certificates
          or percentage interest it holds of record.

        (b)
          Notwithstanding the foregoing section 5.2(a), no legal or beneficial interest
          in
          all or any portion of a residual certificate may be transferred, directly
          or
          indirectly, to a “disqualified organization“ within the meaning of Internal
          Revenue 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 will 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, the
          Certificate Registrar, and the Trustee with an effective Internal Revenue
          Service Form W-8ECI or (iii) a non-U.S. person that has delivered to the
          transferor, the Certificate Registrar, 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
          Internal Revenue Code 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
“Non-permitted Foreign holder”). Furthermore, no legal or beneficial interest in
          all or any portion of a residual certificate may be transferred, directly
          or
          indirectly, to a foreign permanent establishment or fixed base, within
          the
          meaning of an applicable income tax treaty, of the transferee or any other
          person. CMSI will not execute and the Trustee or Authenticating Agent will
          not
          authenticate and deliver, a new residual certificate in connection with
          any
          transfer of a residual certificate, and neither CMSI, the Certificate Registrar
          nor the Trustee will accept a surrender for transfer or registration of
          transfer, or register the transfer of, any residual certificate unless
          the
          transferor will have provided to CMSI, the Certificate Registrar and the
          Trustee
          an affidavit, substantially in the form of 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, a
          Non-permitted Foreign holder, or a person for whom income on the residual
          certificate is attributed to a foreign permanent establishment or fixed
          base,
          within the meaning of an applicable income tax treaty, of the transferee
          or any
          other person, 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 will furnish
          to the
          Internal Revenue Service and the transferor of such residual certificate
          or to
          such Agent, within 60 days of the request

        
          
             

          

          
            93

            
              

            

          

          
             

          

        

        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
          Internal Revenue Code Section 860E(e) as may be required by the Internal
          Revenue
          Code, including but not limited to the present value of the total anticipated
          excess inclusions for 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 will in no event be excused from furnishing
          such
          information. Every holder of a residual certificate will be deemed to have
          consented to such amendments to this 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.

        The
          affidavit described in the preceding paragraph will 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, (iv) will not cause the income for the residual certificate
          to be
          attributable to a foreign permanent establishment or fixed base, within
          the
          meaning of an applicable income tax treaty, of the transferee or any other
          person and (v) 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 and the Certificate Registrar accompanying the affidavit will
          state
          that, after conducting a reasonable investigation of the financial condition
          of
          the transferee, the transferor has no knowledge or reason to know that
          the
          statements made by the transferee for clauses (i) and (iii) of the preceding
          sentence are false. Each residual certificate will bear a legend referring
          to
          the restrictions contained in this paragraph and the preceding
          paragraph.

        Notwithstanding
          the foregoing, no transfer of any private certificate may be made unless
          such
          private certificate has been registered under the Securities Act and applicable
          state securities or “blue sky” laws, or an exemption from the Securities Act and
          applicable state securities or “blue sky” laws is available. Upon surrender for
          registration of transfer of any private certificate, (1) neither the Trustee
          nor
          the Certificate Registrar will accept surrender for transfer or registration
          of
          transfer of, or register the transfer of, any private certificate and (2)
          CMSI
          will not execute, and neither the Trustee nor the Authenticating Agent
          will
          authenticate and deliver, any new private certificate in connection with
          the
          transfer of any private certificate, unless either (A) such private certificate
          has been registered under the Securities Act and applicable state securities
          or
“blue sky” laws, or (B) exemptions from the registration requirements of the
          Securities Act and applicable state securities or “blue sky” laws are available,
          and the transferee delivers to CMSI, the Trustee and the Certificate Registrar
          a
          letter substantially to the effect set forth in exhibit D to this agreement
          and
          (1) if such transferee is not a “Qualified Institutional Buyer” within the
          meaning of Rule 144A of the Securities Act, and if so requested
          by

        
          
             

          

          
            94

            
              

            

          

          
             

          

        

        CMSI,
          an
          opinion of counsel acceptable to CMSI will have been delivered to CMSI,
          the
          Trustee, and the Certificate Registrar, to the effect that such transfer
          is in
          compliance with either subclause (A) or subclause (B) of this clause (i)
          of this
          section 5.2; 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
          Securities Act) and has a net worth (exclusive of primary residence) of
          at least
          $1,000,000 as confirmed in writing to the Trustee and the Certificate
          Registrar.

        Notwithstanding
          the foregoing, any transferee of a legal or beneficial interest in all
          or a
          portion of a private certificate that is a book-entry certificate will
          be deemed
          to have made the representations set forth in exhibit D to this agreement
          including, in clause 2 of such exhibit, the representation that such transferee
          is a “Qualified Institutional Buyer” within the meaning of Rule 144A of the
          Securities Act.

        No
          transfer of an ERISA Restricted Certificate may be made unless any proposed
          transferee (i) executes a representation letter in substantially the form
          of
          exhibit E hereto and in substance satisfactory to the Trustee, the Certificate
          Registrar and CMSI either stating (a) that it is not, and is not acting
          on
          behalf of, any employee benefit plan subject to Title I of ERISA or Section
          4975
          of the Internal Revenue 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 Internal Revenue 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 ERISA Restricted Certificates
          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 for 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 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 and the purchase and holding of such ERISA Restricted
          Certificate is covered by Sections I and III of PTE 95-60 or (ii) provides
          (A)
          an opinion of counsel in form and substance satisfactory to the Trustee,
          the
          Certificate Registrar and CMSI that the purchase or holding of ERISA Restricted
          Certificate by or on behalf of such Plan will not result in the assets
          of the
          Trust being deemed to be “plan assets” and subject to the prohibited transaction
          provisions of ERISA and the Internal Revenue Code or Similar Law and will
          not
          subject CMSI, the Trustee or the Certificate Registrar to any obligation
          in
          addition to those undertaken in this agreement and (B) such other opinions
          of
          counsel, officers’ certificates and agreements as CMSI, the Trustee or the
          Certificate Registrar may require in connection with such transfer.

        The
          applicable representation set forth in clause (i) of the preceding paragraph
          will be deemed to have been made to the Trustee, Certificate Registrar
          and CMSI
          by the acceptance by a transferee of the beneficial interest in any such
          ERISA
          Restricted Certificate, unless the Trustee, Certificate Registrar and CMSI
          will
          have received from the transferee either an

        
          
             

          

          
            95

            
              

            

          

          
             

          

        

        alternative
          representation acceptable in form and substance to the Trustee, Certificate
          Registrar and CMSI or the opinion of counsel and other documentation set
          forth
          in clause (ii) of the preceding paragraph.

         

        5.3
          Mutilated, destroyed, lost or stolen certificates

        If

        ·      any
          mutilated certificate is surrendered to the Certificate Registrar, or the
          Certificate Registrar receives evidence to its satisfaction of the destruction,
          loss or theft of any certificate,

        ·      each
          of CMSI, the Certificate Registrar and the Trustee receive such security
          or
          indemnity as it requires to save it harmless, and

        ·      neither
          the Certificate Registrar nor the Trustee is notified that the certificate
          has
          been acquired by a protected purchaser under Article 8 of the Uniform Commercial
          Code as in effect in the applicable jurisdiction,

        then
          CMSI
          will execute and the Trustee or Authenticating Agent will authenticate
          and
          deliver, in exchange for or in lieu of such mutilated, destroyed, lost
          or stolen
          certificate, a new certificate of like tenor and initial principal balance,
          initial notional balance or percentage interest. In connection with the
          issuance
          of any new certificate under this section 5.3, the Certificate Registrar
          may
          require a payment sufficient to cover any tax or other governmental charge
          imposed and any other expenses (including the fees and expenses of the
          Trustee
          and the Certificate Registrar) in connection with the issuance. Any duplicate
          certificate issued pursuant to this section 5.3 will constitute complete
          and
          indefeasible evidence of ownership in the Trust Fund, as if originally
          issued on
          the closing date, whether or not the lost, stolen or destroyed certificate
          is
          found at any time.

         

        5.4
          Persons deemed owners

        Prior
          to
          due presentation of a certificate for registration of transfer, CMSI, the
          Trustee, any Insurer, the Certificate Registrar and any agent of CMSI,
          the
          Trustee or the Certificate Registrar may treat the person in whose name
          the
          certificate is registered as the owner of the certificate for the purpose
          of
          receiving distributions pursuant to section 3.6 and for all other purposes
          whatsoever, and neither CMSI, the Trustee, any Insurer, the Certificate
          Registrar nor any agent of CMSI, the Trustee or the Certificate Registrar
          will
          be affected by any notice to the contrary.

         

        5.5
          Access to list of certificate holders’ names and addresses

        If
          the
          Trustee is not the Certificate Registrar and requests CMSI or the Certificate
          Registrar to provide a list of the names and addresses of certificate holders,
          CMSI or the Certificate Registrar will furnish to the Trustee, within 15
          days
          after receipt of the request, a list as of the most recent record date,
          in such
          form as the Trustee reasonably requires.

        If
          three
          or more certificate holders

        ·      request
          such information in writing from the Trustee,

        ·      state
          that they desire to communicate with other certificate holders regarding
          their
          rights under this agreement or under the certificates, and

        ·      provide
          a copy of the communication they propose to transmit,

        then
          the
          Trustee will, within five business days after the receipt of the request,
          afford
          the certificate holders 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 the

        
          
             

          

          
            96

            
              

            

          

          
             

          

        

        certificate
          holders’ request, the Trustee will promptly request from CMSI or the Certificate
          Registrar a current list and will afford the certificate holders access
          to the
          list promptly upon its receipt by the Trustee. Every certificate holder,
          by
          receiving and holding a certificate, agrees that neither CMSI, the Certificate
          Registrar nor the Trustee will be held accountable by reason of the disclosure
          of any such information as to the list of the certificate holders, regardless
          of
          the source from which the information is derived.

         

        5.6
          Definitive certificates

        If

        ·      DTC
          advises the Trustee and the Certificate Registrar in writing that the Clearing
          Agency is no longer willing or able properly to discharge its responsibilities
          as depository for the book-entry certificates, and

        ·      CMSI
          is unable to locate a qualified successor,

        the
          Certificate Registrar will notify the beneficial owners, through the Clearing
          Agency, of the occurrence of such event and of the availability of definitive
          certificates to beneficial owners requesting them. Upon surrender to the
          Certificate Registrar by the Clearing Agency of the certificates held of
          record
          by its nominee, accompanied by re-registration instructions and directions
          to
          execute and authenticate new certificates from CMSI, the Trustee or the
          Authenticating Agent will execute and authenticate definitive certificates
          for
          delivery. CMSI will arrange for, and will bear all costs of, the printing
          and
          issuance of the definitive certificates. Neither CMSI, the Trustee, the
          Certificate Registrar nor the Authenticating Agent will be liable for any
          delay
          in delivery of such instructions by the Clearing Agency and may conclusively
          rely on, and will be protected in relying on, such instructions.

         

        5.7
          Notices to Clearing Agency

        Whenever
          notice or other communication to the holders of book-entry certificates
          is
          required under this agreement, until definitive certificates are issued
          to
          beneficial owners pursuant to section 5.6, the Trustee will deliver such
          notices
          and communications to the Clearing Agency.

         

        6
Accounts

        The
          certificate account, distribution account, and any buydown account, escrow
          account, custodial accounts for P&I or servicing account must be eligible
          accounts.

        CitiMortgage
          may transfer any such account to a new eligible account.

        If
          the
          certificate account, distribution account, or any buydown account, escrow
          account, custodial account for P&I or servicing account ceases to be an
          eligible account then within 30 days after such cessation, CitiMortgage
          will

        ·      transfer,
          or direct any third-party servicer, as applicable, to transfer, the account
          that
          has ceased to be an eligible account, and all funds therein, to a new
          certificate account, distribution account, buydown account, escrow account,
          custodial account for P&I or servicing account, respectively, that is an
          eligible account, and

        ·      remit,
          or direct any third-party servicer, as applicable, to remit in accordance
          with
          this agreement, any funds deposited into the account that has ceased to
          be an
          eligible account to the new account.

        In
          lieu
          of taking the actions described above in this section 6, CitiMortgage may
          make
          such other arrangements as to which CitiMortgage, any Insurer and the Trustee
          have received prior written assurance from each rating agency
          that

        
          
             

          

          
            97

            
              

            

          

          
             

          

        

        such
          arrangement will not result in a reduction or withdrawal of the then-current
          rating of any class of certificates.

        7.1
          Events of Default

        If
          any of the following events (Events of Default) is
          continuing:

        (a)
          CitiMortgage, as servicer or master servicer, fails to make a full payment,
          deposit, transfer or distribution required of it in such capacities under
          this
          agreement, and the failure continues unremedied for

        ·      10
          business days after the Trustee gives written notice of the failure to
          CitiMortgage, or the holders of the Required Amount of certificates give
          written
          notice of the failure to CitiMortgage and the Trustee, if the failure results
          from an error in calculating the amount of the required deposit, transfer
          or
          distribution, or

        ·      three
          business days after such notice if the failure results from any other reason;
          or

        (b)
          CitiMortgage fails to reimburse a Paying Agent advance as required by section
          3.5, and the failure is not remedied for 60 business days after the Trustee
          or
          the Paying Agent gives CitiMortgage written notice of the failure, or the
          holders of the Required Amount of Certificates give CitiMortgage and the
          Trustee
          such notice; or

        (c)
          CitiMortgage fails to observe or perform in any material respect any other
          covenant or agreement of CitiMortgage set forth in the certificates or
          in this
          agreement, and the failure

        ·      materially
          and adversely affects the rights of the certificate holders, and

        ·      continues
          unremedied for 60 business days after the Trustee gives CitiMortgage written
          notice of the failure, requiring the failure to be remedied, or the holders
          of
          the Required Amount of Certificates give such notice to CitiMortgage and
          the
          Trustee; or

        (d)
          a
          court or agency or supervisory authority having jurisdiction enters a decree
          or
          order for the appointment of a conservator, receiver or liquidator for
          CitiMortgage in any insolvency, readjustment of debt, marshaling of assets
          and
          liabilities or similar proceeding, or for the winding up or liquidation
          of
          CitiMortgage’s affairs, and the decree or order continues unstayed and in effect
          for 60 consecutive days; or

        (e)
          CitiMortgage consents to the appointment of a conservator, receiver or
          liquidator in an insolvency, readjustment of debt, marshaling of assets
          and
          liabilities, or similar proceeding for CitiMortgage or substantially all
          of its
          property, or CitiMortgage admits in writing its inability to pay its debts
          generally as they become due, files a petition to take advantage of any
          applicable insolvency or reorganization statute, makes an assignment for
          the
          benefit of its creditors, or voluntarily suspends payment of its
          obligations;

        then
          the Trustee or the holders of the Required Amount of certificates, by notice
          in
          writing to CitiMortgage (and to the Trustee if given by the certificate
          holders)
          may terminate all of CitiMortgage’s rights and obligations as servicer of the
          affiliated mortgage loans and as master servicer of the third-party mortgage
          loans under this agreement. Upon CitiMortgage’s receipt of such notice, all
          CitiMortgage’s authority under this agreement, whether for the certificates or
          the mortgage loans or otherwise, will pass to and be vested in the Trustee
          pursuant to this section 7.1, and the Trustee will be authorized to execute
          and
          deliver, on behalf of CitiMortgage as attorney-in-fact or

        
          
             

          

          
            98

            
              

            

          

          
             

          

        

        otherwise,
          any documents and other instruments, and to do or accomplish all other
          acts or
          things necessary or appropriate to effect the purposes of such notice,
          whether
          to complete the transfer and endorsement of the mortgage loans and related
          documents or otherwise. CitiMortgage will cooperate with the Trustee in
          effecting the termination of CitiMortgage’s responsibilities and rights
          hereunder, including the transfer to the successor servicer for the
          administration by it of all cash amounts held by CitiMortgage for deposit,
          or
          deposited by CitiMortgage, in the certificate account or servicing account
          or
          subsequently received on the mortgage loans. In addition to any other amounts
          that are then payable, or, notwithstanding the termination of its activities
          as
          servicer and master servicer of the mortgage loans, may become payable
          to
          CitiMortgage under this agreement, CitiMortgage will be entitled to receive
          out
          of any delinquent interest payment on a mortgage loan, due before such
          termination notice but received afterwards, that portion of the payment
          that it
          would have received if the notice had not been given.

         

        7.2
          Trustee to act; appointment of successor

        Once
          CitiMortgage receives a notice of termination under section 7.1, the Trustee
          will be the successor in all respects to CitiMortgage in its capacity as
          servicer and master servicer, and will be subject to all CitiMortgage’s rights
          and obligations under this agreement. As compensation, the Trustee will,
          except
          as provided in section 7.1, be entitled to the same compensation (whether
          payable out of the certificate account or otherwise) as CitiMortgage would
          have
          been entitled to under this agreement if no such notice of termination
          had been
          given. However, the Trustee may, if it is unwilling so to act, or will,
          if it is
          legally unable so to act, appoint, or petition a court of competent jurisdiction
          to appoint, an established housing finance institution with a net worth
          of not
          less than $5 million and approved as seller/servicer by GNMA, Fannie Mae
          or
          Freddie Mac as the successor to CitiMortgage in the assumption of all or
          any
          part of the rights and obligations of CitiMortgage under this agreement.
          Until
          such a successor is appointed, unless the Trustee is prohibited by law
          from so
          acting, the Trustee will act in such capacity as provided above. The Trustee
          may
          make such arrangements for compensation of such successor out of payments
          on the
          mortgage loans as it and the successor agree; provided, however, that
          no such compensation will exceed CitiMortgage’s compensation under this
          agreement. The Trustee and the successor will take any actions, consistent
          with
          this agreement, necessary to effect the succession.

        The
          Trustee will promptly notify the certificate holders and any Insurer of
          any
          termination of CitiMortgage or appointment of a successor pursuant to this
          section 7.

The
          Trustee

         

        8.1
          Duties 

        (a)
          Unless the Trustee has notice that an Event of Default is continuing, the
          Trustee will only have those obligations that are specifically set forth
          in this
          agreement, and no implied covenants of the Trustee will be read into this
          agreement.

        (b)
          If
          the Trustee has notice that an Event of Default is continuing, then
          notwithstanding anything to the contrary in this agreement, the Trustee
          will
          exercise those rights and powers vested

        
          
             

          

          
            99

            
              

            

          

          
             

          

        

        in
          it by
          this agreement, and use the same degree of care and skill in their exercise,
          as
          a prudent man would exercise under 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 prudent in the circumstances,
          the Trustee will consider, to the extent applicable, the matters enumerated
          in
          Section 126(2)(a) through (e) of the New York Real Property Law, as in
          effect on
          the date of this agreement, and will comply with subdivisions (3),(4) and
          (5) of
          Section 126 of the New York Real Property Law, as in effect on the date
          of this
          agreement.

        The
          Trustee will not be charged with notice of an Event of Default (other than
          a
          default in payment to the Trustee) unless a Responsible Officer of the
          Trustee
          obtains actual knowledge of such failure or receives written notice of
          such
          Event of Default at its corporate trust office from CitiMortgage or the
          holders
          of the Required Amount of Certificates.

        (c)        The
          Trustee, upon receipt of all resolutions, certifications, statements, opinions,
          reports, documents, orders or other instruments that are specifically required
          or requested to be furnished to the Trustee pursuant to this agreement
          (each a
Furnished Document), will examine them to determine whether they
          conform to the requirements of this agreement. The Trustee may request
          an
          officer’s certificate as to any matter of fact if the Trustee believes it
          desirable that the fact be established before the Trustee takes an action
          under
          this agreement. Unless the Trustee has notice that an Event of Default
          is
          continuing, the Trustee may conclusively rely, without investigation, on
          the
          truth of the statements and the correctness of the opinions expressed in
          any
          Furnished Document that the Trustee believes to be genuine, signed or presented
          by the proper parties, and in conformity with the requirements of this
          agreement.

        The
          Trustee will investigate the facts or matters stated in a Furnished Document
          if
          the holders of the Required Amount of Certificates request such investigation
          in
          writing. CitiMortgage will pay, or will reimburse the Trustee upon demand,
          for
          the reasonable expense of such investigation. If the Trustee believes that
          the
          payment within a reasonable time of the costs and liabilities likely to
          be
          incurred in the investigation are not reasonably assured to it, the Trustee
          may,
          as a condition to conducting such investigation, require reasonable indemnity
          from the certificate holders against such expense or liability. Nothing
          in this
          clause (c) will derogate from CitiMortgage’s obligation to observe any
          applicable law prohibiting disclosure of information regarding the
          mortgagors.

        (d)                  The
          Trustee will not be required to expend or risk its own funds or otherwise
          incur
          financial liability in the performance of any of its duties under this
          agreement, or in the exercise of any of its rights or powers, if the Trustee
          reasonably believes that the repayment of such funds or adequate indemnity
          against such risk or liability is not reasonably assured to it.

        (e)        Except
          to the extent that the Trustee becomes a successor servicer to CitiMortgage
          under sections 4.3 or 7.2, the Trustee will have no responsibility for
          the
          performance or the manner of performance of any of CitiMortgage’s obligations
          under this agreement. The relationship of CitiMortgage to the Trustee under
          this
          agreement is intended by the parties to be that of an independent contractor
          and
          not that of a joint venturer, partner or agent.

        
          
             

          

          
            100

            
              

            

          

          
             

          

        

        (f)        The
          Trustee may appoint agents (which may include CitiMortgage and its affiliates)
          to perform any of the Trustee’s obligations under this agreement. Such agents
          will have all of the rights and obligations of the Trustee conferred on
          them by
          such appointment, but the Trustee will continue to be responsible for its
          obligations under this agreement.

         

        8.2
          Liability 

        (a)           In
          performing its obligations under this agreement, the Trustee will be liable
          for
          its own negligence or misconduct, except that the Trustee will not be
          liable for

        ·      an
          error of judgment by a Responsible Officer of the Trustee, unless the Trustee
          was negligent in ascertaining the pertinent facts;

        ·      an
          action by the Trustee believed by it to be permitted under this agreement;
          and

        ·      an
          action taken 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.

        (b)        The
          Trustee may consult with counsel, and an opinion of counsel will be full
          and
          complete authorization and protection for any action by the Trustee taken
          under
          this agreement in accordance with such opinion.

        (c)        The
          Trustee will not be responsible for the selection of the Mortgage Note
          Custodian
          or any, Paying Agent, Certificate Registrar, or Authenticating Agent, nor
          for
          their performance of their obligations under this agreement, the Mortgage
          Note
          Custodial Agreement, or any other applicable agreement.

         

        8.3
          Trustee not liable for certificates or mortgage loans

        The
          recitals contained herein and in the certificates (other than the certification
          of authentication on the certificates) will be taken as the statements
          of
          CitiMortgage, and the Trustee assumes no responsibility for the correctness
          of
          the same. The Trustee makes no representations as to the validity or sufficiency
          of this agreement, the Mortgage Note Custodial Agreement or of the certificates
          (other than the certification of authentication on the certificates) or
          of any
          mortgage loan or related document. The Trustee will not be accountable
          for the
          use or application by CitiMortgage of any of the certificates or of the
          proceeds
          of such certificates or for the use or application of any funds paid to
          CitiMortgage in respect of the mortgage loans or deposited in or withdrawn
          from
          the certificate account or servicing account by CitiMortgage. The Trustee
          will
          have no liability for any losses incurred as a result of

        ·      any
          failure of the Trust Fund to qualify as the specified separate constituent
          REMICs,

        ·      any
          termination, inadvertent or otherwise, of the status of the Trust Fund
          as the
          specified separate constituent REMICs,

        ·      any
          tax on prohibited transactions imposed by Internal Revenue Code Section
          860F(a)(1),

        ·      any
          tax on net income from foreclosure property imposed by Internal Revenue
          Code
          Section 860G(c),

        ·      any
          tax on contributions to any constituent REMIC after the startup day imposed
          by
          Internal Revenue Code Section 860G(d),

        ·      any
          erroneous calculation or determination or any act or omission of CitiMortgage
          hereunder or

        
          
             

          

          
            101

            
              

            

          

          
             

          

        

        ·      any
          erroneous information included in any federal, state or local income tax
          or
          information return prepared pursuant to section 3.16;

        provided,
          that the Trustee will not be excused hereby from liability for its own
          negligence, bad faith or failure to perform its duties as specified
          herein.

         

        8.4
          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 and may otherwise deal with CitiMortgage or any of its
          affiliates as if it were not the Trustee.

         

        8.5
          Trustee’s fees and expenses

        The
          Trustee’s fees and expenses (and those of any co-trustee appointed pursuant to
          section 8.10), and of any Certificate Registrar, Mortgage Note Custodian,
          Depository, Paying Agent, Authenticating Agent appointed pursuant to section
          8.12, and agent of the Trustee appointed pursuant to section 8.2(g), will
          be
          paid by CitiMortgage, as servicer, in accordance with section 3.9(a). Citibank,
          N.A., as Paying Agent, has agreed to a fee of $3,000 a year. CitiMortgage
          will
          also pay any expenses associated with the resignation or removal of the
          Trustee
          and the appointment of a successor Trustee.

        In
          consideration of paying the amounts payable pursuant to this section 8.5,
          CitiMortgage may retain any trustee fee that may be payable on the third-party
          mortgage loans. The Trustee (and any such co-Trustee) will be entitled
          to
          reasonable compensation (which will 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 CitiMortgage, the Trustee will be paid or reimbursed
          by CitiMortgage 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 certificate
          holders hereunder.

        The
          Trustee and each Certificate Registrar, Mortgage Note Custodian, Depository,
          Paying Agent, Authenticating Agent and any agent appointed pursuant to
          section
          8.2 are entitled to indemnification from CitiMortgage, 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 will survive the
          payment
          of the certificates and termination of the Trust Fund, as well as the
          resignation or removal of CitiMortgage as servicer (if such action which
          caused
          the need for the indemnification occurred while CitiMortgage acted as servicer),
          and for purposes of such indemnification neither the negligence nor bad
          faith of
          any of the entities enumerated in the preceding sentence, nor of any Mortgage
          Note

        
          
             

          

          
            102

            
              

            

          

          
             

          

        

        Custodian,
          will be imputed to, or adversely affect, the right of any other entity
          enumerated in the preceding sentence to be entitled to
          indemnification.

         

        8.6
          Eligibility requirements for Trustee

        The
          Trustee hereunder will at all times be a corporation or a national banking
          association, other than an affiliate of CitiMortgage, having its principal
          office in, and organized and doing business under the laws of, the United
          States
          of America or a state thereof, authorized under such laws to exercise corporate
          trust powers, having a combined capital and surplus of at least $30 million,
          and
          subject to supervision or examination by federal or state authority and
          having a
          short-term debt rating of at least A-2 from S&P (or a long-term debt rating
          of BBB+ if it has no short-term debt rating) if S&P is a rating agency, A-2
          from Moody’s (or a long-term debt rating of Baa1 if it has no short-term debt
          rating) if Moody’s is a rating agency, and F1 from Fitch (or a long-term debt
          rating of A if it has no short-term debt rating) if Fitch is a rating
          agency.  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 8.6, the combined capital and surplus of such corporation
          or
          national banking association will be deemed to be its combined capital
          and
          surplus as set forth in its most recent report of condition so published.
          If the
          Trustee ceases to be eligible in accordance with the provisions of this
          section
          8.6, the Trustee will resign immediately in the manner and with the effect
          specified in section 8.7.

        Any
          successor trustee will have a credit rating or be otherwise acceptable
          to the
          rating agencies so that no rating agency will reduce its then current rating
          of
          any class of certificates.

         

        8.7
          Resignation or removal of Trustee

        The
          Trustee may resign and be discharged from the trusts hereby created by
          giving
          written notice thereof to CitiMortgage. Upon receiving such notice of
          resignation, CitiMortgage will promptly appoint a successor Trustee by
          written
          instrument, in duplicate, one copy of which instrument will be delivered
          to the
          resigning Trustee and one copy to the successor Trustee. If no successor
          Trustee
          will 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
          the
          Trustee ceases to be eligible in accordance with the provisions of section
          8.6
          and will fail to resign after written request therefor by CitiMortgage,
          or if
          the Trustee is legally unable to act, or is adjudged a bankrupt or insolvent,
          or
          a receiver of the Trustee or of its property is appointed, or any public
          officer
          takes charge or control of the Trustee or of its property or affairs for
          the
          purpose of rehabilitation, conversion or liquidation, then CitiMortgage
          may
          remove the Trustee. If it removes the Trustee under the authority of the
          immediately preceding sentence, CitiMortgage will promptly appoint a successor
          Trustee by written instrument, in duplicate, one copy of which instrument
          will
          be delivered to the Trustee so removed and one copy to the successor
          Trustee.

        The
          Trustee may also be removed (i) by CitiMortgage, (a) if the Trustee ceases
          to be
          eligible to continue as such under this agreement or if the Trustee
          becomes

        
          
             

          

          
            103

            
              

            

          

          
             

          

        

        insolvent,
          (b) if the Trustee breaches any of its duties under this agreement which
          materially adversely affects the certificate holders, (c) if through the
          performance or nonperformance of certain actions by the Trustee, the rating
          assigned by any rating agency to any class of certificates 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 any class of certificates being lowered;
          or
          (ii) by the holders of certificates evidencing more than 50% of the voting
          interest of the 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 8.7 will not become effective
          until acceptance of appointment by the successor Trustee as provided in
          section
          8.8.

         

        8.8
          Successor trustee

        Any
          successor Trustee appointed as provided in section 8.7 will execute, acknowledge
          and deliver to CitiMortgage and to its predecessor Trustee an instrument
          accepting such appointment hereunder, and thereupon the resignation or
          removal
          of the predecessor Trustee will become effective and such successor Trustee,
          without any further act, deed or conveyance, will 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
          will
          deliver to the successor Trustee all mortgage files and related documents
          and
          statements held by it hereunder; and, if any mortgage notes are then held
          by the
          Mortgage Note Custodian pursuant to a Mortgage Note Custodial Agreement,
          the
          predecessor Trustee and the Mortgage Note Custodian will amend such Mortgage
          Note Custodial Agreement to make the successor Trustee the successor to
          the
          predecessor Trustee thereunder; and CitiMortgage and the predecessor Trustee
          will 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 will accept appointment as provided in this section 8.8
          unless
          at the time of such acceptance such successor Trustee will be eligible
          under the
          provisions of section 8.6.

        Upon
          acceptance of appointment by a successor Trustee as provided in this section
          8.8, CitiMortgage will mail notice of the succession of such Trustee hereunder
          to all holders of certificates at their addresses as shown in the Certificate
          Register, to the Rating Agencies and to any Insurer. If CitiMortgage fails
          to
          mail such notice within 10 days after acceptance of appointment by the
          successor
          Trustee, the successor Trustee will cause such notice to be mailed at the
          expense of CitiMortgage.

         

        8.9
          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 will be a party, or any corporation
          or
          national banking association succeeding to all or substantially all of
          the
          corporate trust business of the Trustee, will be the successor of the Trustee
          hereunder,

        
          
             

          

          
            104

            
              

            

          

          
             

          

        

        provided
          such corporation or national banking association will be eligible under
          the
          provisions of section 8.6, 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.

         

        8.10
          Appointment of co-trustee or separate trustee

        Notwithstanding
          any other provisions of this agreement, 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, CitiMortgage and
          the
          Trustee acting jointly will have the power and will 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 certificate
          holders and any Insurer, 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 CitiMortgage and the Trustee may consider
          necessary and desirable. If CitiMortgage will 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 will have occurred and be continuing, the
          Trustee
          alone will have the power to make such appointment. No co-trustee or separate
          trustee hereunder will be required to meet the terms of eligibility as
          a
          successor trustee under section 8.6 and no notice to the certificate holders
          of
          the appointment of any co-trustee or separate trustee will be required
          under
          section 8.8.

        Every
          separate trustee and co-trustee will, 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
          will 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 or acts are to be performed (whether
          as
          Trustee hereunder or as successor to CitiMortgage hereunder), the Trustee
          will
          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) will be exercised
          and performed singly by such separate trustee or co-trustee, but solely
          at the
          direction of the Trustee;

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

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

        Any
          notice, request or other writing given to the Trustee will 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 will refer to this agreement and the conditions of this section
          8.
          Each separate trustee and co-

        
          
             

          

          
            105

            
              

            

          

          
             

          

        

        trustee,
          upon its acceptance of the trusts conferred, will 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 will
          be filed
          with the Trustee and a copy thereof given to CitiMortgage.

        Any
          separate trustee or co-trustee may 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 will die, become
          incapable of acting, resign or be removed, all of its estates, properties,
          rights, remedies and trusts will vest in and be exercised by the Trustee
          to the
          extent permitted by law, without the appointment of a new or successor
          trustee.

         

        8.11
          Tax returns

        The
          Trustee, upon request, will furnish CitiMortgage 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 each constituent REMIC.
          The
          Trustee will sign the federal and, if applicable, state and local income
          tax
          returns of each constituent REMIC.

         

        8.12
          Appointment of authenticating agent

        As
          long
          as any of the certificates remain outstanding the Trustee may appoint an
          Authenticating Agent or Agents (which may include CitiMortgage or any of
          its
          affiliates) which will be authorized to act on behalf of the Trustee to
          authenticate certificates, and certificates so authenticated will be entitled
          to
          the benefit of this agreement and will 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 certification of authentication, such reference will be deemed to
          include authentication and delivery on behalf of the Trustee by an
          Authenticating Agent and a certification of authentication executed on
          behalf of
          the Trustee by an Authenticating Agent. Each Authenticating Agent will
          be
          acceptable to CitiMortgage and will 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 million, authorized under such laws to conduct
          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 will be deemed to be its
          combined capital and surplus as set forth in its most recent report of
          condition
          so published. If an Authenticating Agent ceases to be eligible in accordance
          with the provisions of this section 8.12, such Authenticating Agent will
          resign
          immediately in the manner and with the effect specified in this section
          8.12.

        Any
          corporation or national banking association into which an authenticating
          Agent
          may be merged in or converted or

        
          
             

          

          
            106

            
              

            

          

          
             

          

        

        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 will be a party, or any corporation or national banking
          association succeeding to the corporate agency or corporate trust business
          of an
          Authenticating Agent, will continue to be an Authenticating Agent, provided
          such
          corporation or national banking association will 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 by giving written notice thereof to the
          Trustee
          and to CitiMortgage. The Trustee may terminate the agency of an Authenticating
          Agent by giving written notice thereof to such Authenticating Agent and
          to
          CitiMortgage. Upon receiving such a notice of resignation or upon such
          a
          termination, or if the Authenticating Agent ceases to be eligible in accordance
          with the provisions of this section 8.12, the Trustee may appoint a successor
          acceptable to CitiMortgage and will mail written notice of such appointment
          by
          first-class mail, postage prepaid to all certificate holders as their names
          and
          addresses appear in the Certificate Register, and to any Insurer. Any successor
          Authenticating Agent upon acceptance of its appointment hereunder will
          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 will 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 will be a reimbursable expense pursuant to section 8.5
          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 certification of authentication,
          an alternate certification of authentication in the following form:

        “This
          is
          one of the certificates referred to in the within-mentioned
          Agreement.

          Termination

         

        9.1
          Termination upon repurchase by CMSI or liquidation of all mortgage
          loans

        The
          obligations and responsibilities of CMSI, CitiMortgage and the Trustee
          under,
          and the Trust Fund created by, this agreement will 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, 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 certificate
          holders
          and to the Insurer, as subrogee of any insured class certificates, of all
          amounts required to be paid to them pursuant to this agreement;

        provided,
          however, that in no event will the trust created hereby
          continue

        
          
             

          

          
            107

            
              

            

          

          
             

          

        

        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.

        CMSI’s
          right to repurchase all of the mortgage loans on any distribution day pursuant
          to clause (a) above will be conditioned upon

        ·      the
          aggregate scheduled principal balances of such mortgage loans, at the time
          of
          any such repurchase and after giving effect to distributions to be made
          on such
          distribution day, aggregating an amount less than 10% of the aggregate
          scheduled
          principal balance of the mortgage loans as of the closing date, which amount
          is
          set forth in the Series Terms and

        ·      any
          other condition set forth in the Series Terms.

        The
          repurchase of the mortgage loans and other property under clause (a) above
          will
          be at a price equal to the sum of

        ·      100%
          of the unpaid principal 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 pass-through rate for each mortgage
          loan
          to but not including the first day of the month in the month in which the
          related distribution is made to certificate holders, after the deduction
          of (x)
          unreimbursed voluntary advances, affiliated Paying Agent advances, third-party
          Paying Agent advances, and advance account advances (other than such payments
          and advances in respect of interest in excess of the pass-through rate
          on the
          mortgage loans) made prior to the month of repurchase, whereupon such voluntary
          advances, affiliated Paying Agent advances, third-party Paying Agent advances
          and advance account advances will be reimbursed to the Paying Agent or
          deemed
          reimbursed to CitiMortgage, as the case may be, by such deductions, and
          (y) the
          aggregate amount of any non-supported prepayment interest shortfalls for
          the
          distribution day in the month of such repurchase, and

        ·      the
          appraised value of any acquired property in the Trust Fund (less the good
          faith
          estimate of CitiMortgage of liquidation expenses to be incurred in connection
          with its disposal thereof), such appraisal to be conducted by an appraiser
          mutually agreed upon by CitiMortgage and the Trustee.

        Notwithstanding
          anything to the contrary in this section 9.1, if the purchase price of
          the
          mortgage loans under clause (a) above would be less than the aggregate
          fair
          market value of the mortgage loans on the first day of the month of repurchase
          (after giving effect to payments of principal due on such first day), then
          CMSI
          may so repurchase the mortgage loans only if the repurchase would be permitted
          under then-applicable risk-based capital rules applicable to securitizations
          treated as sales.

        Any
          method of termination or repurchase of the Trust Fund other than as provided
          in
          clauses (a) or (b) 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 Internal Revenue Code Section
          860F(a)(4)(A), will not adversely affect the status of the Trust Fund as
          separate constituent REMICs under the Internal Revenue Code and will not
          otherwise subject the Trust Fund to any tax. CMSI may transfer its right
          to

        
          
             

          

          
            108

            
              

            

          

          
             

          

        

        repurchase
          all of the mortgage loans pursuant to clause (a) above to any third party
          of
          choice.

        Such
          termination will occur only in connection with a “qualified liquidation” of each
          constituent REMIC within the meaning of Internal Revenue Code Section
          860F(a)(4)(A), pursuant to which the Trustee will sell or otherwise dispose
          of
          all of the remaining assets of the Trust Fund and make all required
          distributions to certificate holders within 90 days of the adoption of
          a plan of
          complete liquidation. For this purpose, the notice of termination described
          in
          the next paragraph will be the adoption of a plan of complete liquidation
          described in Internal Revenue Code Section 860F­(a)(4)­(A)(i), which
          will be deemed to occur on the date the first such notice is mailed. Such
          date
          will be specified in the final federal income tax return of each constituent
          REMIC constituted by the Trust Fund.

        Notice
          of
          a termination, specifying the distribution day upon which the certificate
          holders may surrender their certificates to the Paying Agent for payment
          of the
          final distribution and cancellation, will be given promptly by the Trustee
          by
          letter to the certificate holders mailed not earlier than 30 days nor more
          than
          60 days prior to such distribution day specifying

        
          	
                  ·

                	
                  the
                    distribution day upon which final payment of the certificates
                    will be made
                    upon presentation and surrender of the certificates at the office
                    of the
                    Paying Agent designated in the
                    notice,

                

        

        
          	
                  ·

                	
                  the
                    amount of the final distribution,
                    and

                

        

        
          	
                  ·

                	
                  that
                    the record date otherwise applicable to such distribution day
                    will not
                    apply, and that distributions will be made only upon presentation
                    and
                    surrender of the certificates at the designated office of the
                    Paying
                    Agent.

                

        

        CMSI
          will
          give such notice to the Trustee and, if applicable, the Certificate Registrar,
          the Mortgage Note Custodian, and the Paying Agent at the time the notice
          is
          given to the certificate holders.

        If
          such
          notice is given, CMSI will deposit in the certificate account or the account
          designated by the Paying Agent, on the business day preceding the distribution
          day for the final distribution, an amount equal to the final distribution
          on 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 section 9.1 have been
          met, the
          Trustee will promptly direct the Mortgage Note Custodian and CitiMortgage
          to
          release the related mortgage file to CMSI.

        If
          all of
          the certificate holders do not surrender their certificates for cancellation
          within six months after the date specified in the notice, the Trustee will
          give
          a second written notice to the remaining certificate holders to surrender
          their
          certificates for cancellation and receive the final distribution. If all
          the
          certificates have not been surrendered for cancellation within one year
          after
          the second notice, the Trustee may take appropriate steps to contact the
          remaining certificate holders concerning surrender of their certificates,
          and
          the cost thereof will be paid out of the funds and other assets which remain
          subject hereto. Interest will not accrue for the period of any delay in
          the
          payment of a certificate resulting from the failure of a holder to surrender
          the
          certificate in accordance with the notice.

General
          provisions

         

        10.1
          Amendments

        This
          Agreement may be amended by the parties, without the consent of any of
          the
          certificate holders,

        ·      to
          cure an ambiguity or inconsistency, or to correct a mistake,

        ·      to
          add provisions not inconsistent with this agreement,

        ·      to
          comply with any requirements imposed by the Internal Revenue Code,

        ·      to
          establish a “qualified reserve fund” within the meaning of Internal Revenue Code
          Section 860G(a)(7)(B), or

        ·      to
          maintain the status of the Trust Fund as separate constituent
          REMICs.

        This
          Agreement may also be amended by the parties, without certificate holder
          consent, if CMSI or CitiMortgage delivers an opinion of counsel acceptable
          to
          the Trustee and the Insurer to the effect that the amendment will not materially
          adversely affect the interests of the certificate holders or the
          Insurer.

        The
          Trustee will execute and deliver any amendment to this agreement provided
          by
          CMSI or CitiMortgage that conforms to the preceding two paragraphs, but
          the
          Trustee need not enter into any such amendment that affects the Trustee’s own
          rights, duties or immunities under this agreement or otherwise.

        This
          Agreement may also be amended by the parties to add, change or eliminate
          provisions of this agreement, or to modify the rights of certificate holders;
          with the consent of

        1      the
          holders of 2/3 of the certificates,

        2      if
          a class of certificates is affected materially and adversely by the amendment
          in
          a way that is different from the other affected classes, 2/3 of the certificates
          of the differently affected class, and

        3      the
          Insurer if the Insurer is materially and adversely affected by the
          amendment.

        Approval
          will be by percentage interest for residual certificates and by principal
          balance for all other certificates.

        In
          connection with any such amendment, CMSI or CitiMortgage will deliver an
          opinion
          of counsel acceptable to the Trustee (x) identifying any class of certificates
          that may be affected materially and adversely by the amendment in a way
          that is
          different from the other affected classes (or stating that there is no
          such
          differently affected class) and (y) identifying any class whose certificate
          holders would not be materially adversely affected by such
          amendment.

        Notwithstanding
          the foregoing, no amendment will, without the consent of the holders of
          all the
          outstanding certificates

        ·      reduce
          or delay collections or payments received on mortgage loans or distributions
          to
          be made on any certificate, or

        ·      
          reduce the proportion required to consent to any such amendment.

        Certificate
          holders may consent to an amendment by approving the substance of the amendment
          rather than the particular form of the proposed amendment. The Trustee
          may
          prescribe reasonable requirements for the manner of obtaining and evidencing
          such consents. Any proposed amendment is subject to the receipt by the
          Trustee
          of a legal opinion, at the expense of the party proposing the amendment
          (or at
          the expense of the Trust Fund if proposed by the Trustee), that the amendment
          will not cause any constituent REMIC to fail to qualify as a REMIC or subject
          any constituent REMIC to tax.

        
          
             

          

          
            110

            
              

            

          

          
             

          

        

        Promptly
          after the execution of any such amendment or such consent, the Trustee
          will
          notify each certificate holder of the substance of the amendment or provide
          the
          holder with a copy of the amendment.

         

        10.2
          Recordation of Agreement

        Any
          manually signed copy of this agreement may be recorded in any appropriate
          public
          office for real property records in a county or other jurisdiction where
          mortgaged properties are located, or any other appropriate public recording
          office. CitiMortgage will effect such recordation at its expense upon the
          Trustee’s request, acting at the direction of the holders of a majority by
          percentage interest of the residual certificates. The request must be
          accompanied by a legal opinion to the effect that the recording will materially
          and beneficially affect the interests of the certificate holders.

         

        10.3
          Limitation on rights of certificate holders

        A
          certificate holder’s death or incapacity will not terminate this agreement or
          the Trust Fund, nor entitle the certificate holder’s legal representatives or
          heirs to claim an accounting or to take an action or commence a proceeding
          in
          any court for a partition or winding up of the Trust Fund, nor otherwise
          affect
          the rights, obligations and liabilities of any party to this
          agreement.

        No
          certificate holder may vote (except as provided in section 10.1) or otherwise
          control the operation and management of the Trust Fund or the obligations
          of the
          parties, nor will anything in this agreement or the certificates be construed
          to
          constitute the certificate holders as partners (except to the extent provided
          in
          Internal Revenue Code Section 860F(e) for holders of residual certificates)
          or
          members of an association; nor will a certificate holder be liable to any
          third
          person for any action taken by the parties to this agreement pursuant to
          its
          provisions.

        A
          certificate holder may not institute any suit, action or proceeding with
          respect
          to this agreement, unless

        ·      the
          holder has notified the Trustee of the continuance of an Event of
          Default,

        ·      the
          holders of the Required Amount of certificates have requested the Trustee
          to
          institute such action, suit or proceeding in its own name as Trustee, and
          have
          offered the Trustee such reasonable indemnity as it requires against the
          costs,
          expenses and liabilities to be incurred, and

        ·      the
          Trustee, for 60 days after its receipt of the notice, request and offer
          of
          indemnity, fails to institute any the action, suit or proceeding.

        Each
          certificate holder understands, and agrees with every other certificate
          holder
          and the Trustee, that no certificate holders may under this agreement affect,
          disturb or prejudice the rights of any other certificate holders, or obtain
          priority over or preference to any such other holders, or enforce any right
          under this agreement, except as provided in this agreement, and for the
          equal,
          ratable and common benefit of all certificate holders. For the protection
          and
          enforcement of the provisions of this section 10.3, each certificate holder
          and
          the Trustee may seek such relief as can be given either at law or in
          equity.

         

        10.4
          Governing law

        This
          Agreement and the certificates will be governed by the laws of the State
          of New
          York, except that the immunities and standards of care of the Trustee will
          be
          governed by the law of the jurisdiction in which its corporate trust office
          is
          located.

        
          
             

          

          
            111

            
              

            

          

          
             

          

        

         

        10.5
          Maintenance of REMICS

        The
          execution and delivery of this agreement will constitute an acknowledgment
          by
          each of CMSI and CitiMortgage on behalf of the certificate holders that
          it
          intends hereby to establish and maintain (for federal income tax purposes)
          one
          or more “real estate mortgage investment conduits” within the meaning of
          Internal Revenue Code Section 860D, and CMSI and CitiMortgage are hereby
          granted
          all necessary powers to further such intent.

         

        10.6
          Notices

        Except
          as
          otherwise stated in this agreement, all communications relating to this
          agreement including all demands and notices will be in writing and will
          be
          deemed to have been duly given if personally delivered at or mailed by
          first
          class mail, to a party at the address for notices set forth in the Series
          Terms
          or at such other address as the party designates in a written notice to
          each
          other party. Any notice required or permitted to be mailed to a certificate
          holder will be given by first class mail, postage prepaid, at the holder’s
          address shown in the Certificate Register. Any notice so mailed within
          the time
          prescribed in this agreement will be conclusively presumed to have been
          duly
          given, whether or not the certificate holder receives the notice. Notices
          to the
          Trustee will be effective only upon receipt.

         

        10.7
          Severability of provisions

        If
          a
          provision of this agreement is held invalid, then such provisions will
          be deemed
          severable from the remaining provisions of this agreement and will in no
          way
          affect the validity or enforceability of the other provisions, or of the
          certificates or the rights of their holders.

         

        10.8
          Assignment

        Notwithstanding
          anything to the contrary in this agreement, except as provided in sections
          4.2,
          4.3 and 4.5, CMSI or CitiMortgage may not assign this agreement without
          the
          prior consent of the Trustee and the holders of 2/3 of the outstanding
          certificates and 2/3 of the percentage interests of the outstanding residual
          certificates.

         

        10.9
          Certificates nonassessable and fully paid

        It
          is the
          intention of the Trustee that the certificate holders will not be personally
          liable for obligations of the Trust Fund, that the interests represented
          by the
          certificates will be nonassessable for any losses or expenses of the Trust
          Fund
          or for any reason whatsoever, and that the certificates upon authentication
          thereof by the Trustee pursuant to section 2.5 are and will be deemed fully
          paid.

      COUNTY
        OF   )

       

      [___________],
        being first duly sworn, deposes and says:

      1.           That
        he is [______________] of [_____________] (the “Investor”), a [state type of
        entity] duly organized and existing under the laws of the [State of
        ____________] [United States], on behalf of which he makes this
        affidavit.

       

      2.           That
        the Investor’s Taxpayer Identification Number is [______________].

       

      3.           That
        the Investor is not a “disqualified organization” within the meaning of Section
        860E(e)(5) of the Internal Revenue Code of 1986, as amended (the “Internal
        Revenue Code”) or an ERISA Prohibited holder, and will not be a “disqualified
        organization” or an ERISA Prohibited holder as of [______, _______], and that
        the Investor is not acquiring a Citicorp Mortgage Securities Trust, Series
        200[   ]-[  ] REMIC Pass-Through Certificates, class
        [PR][LR][R] certificates (the “residual certificates”) for the account of, or as
        agent (including a broker, nominee or other middleman) for, any person or
        entity
        from which it has not received an affidavit substantially in the form of
        this
        affidavit. For these purposes, a “disqualified organization” means the United
        States, any state or political subdivision thereof, any foreign governments
        any
        international organization, any agency or instrumentality of any of the
        foregoing (other than an instrumentality if all of its activities are subject
        to
        tax and a majority of its board of directors is not appointed by such
        governmental entity), any cooperative organization furnishing electric energy
        or
        providing telephone service to persons in rural areas described in Internal
        Revenue Code Section 1381(a)(2)(C), or any organization (other than a farmers’
cooperative described in Internal Revenue Code Section 521) that is exempt
        from
        federal income tax unless such organization is subject to the tax on unrelated
        business income imposed by Internal Revenue Code Section 511. For these
        purposes, an “ERISA Prohibited holder” means an employee benefit plan the
        investment of which is regulated under Section 406 of the Employee Retirement
        Income Security Act of 1974, as amended, or Internal Revenue Code Section
        4975
        or a governmental plan, as defined in Section 3(32) of ERISA, subject to
        any
        federal, state or local law which is, to a material extent, similar to the
        foregoing provisions of ERISA or the Internal Revenue Code (collectively,
        a
“Plan”) or a person investing the assets of a Plan.

       

      4.           That
        the Investor historically has paid its debts as they have come due and intends
        to pay its debts as they come due in the future and the Investor intends
        to pay
        taxes associated with holding the residual certificates as they become
        due.

       

      5.           That
        the Investor will not cause the income with respect to the residual certificates

      8.           That
        the Investor (i) is not a Non-U.S. person or (ii) is a Non-U.S. person that
        holds the residual certificates 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 W-8ECI or (iii) is
        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 certificates to it is in accordance with the requirements
        of the
        Internal Revenue Code and the regulations promulgated thereunder and that
        such
        transfer of the residual certificates will not be disregarded for federal
        income
        tax purposes. “Non-U.S. person” will mean an individual, corporation,
        partnership or other person other than a “U.S. person.” “U.S. person” will mean
        a citizen or resident of the United States, a corporation, partnership (except
        to the extent provided in applicable Treasury regulations) or other entity
        created or organized in or under the laws of the United States or any political
        subdivision thereof, an estate that is subject to U.S. federal income tax
        regardless of the source of its income or a trust if a court within the United
        States is able to exercise primary supervision over the administration of
        such
        trust, and one or more such U.S. persons have the authority to control all
        substantial decisions of such trust (or, to the extent provided in applicable
        Treasury regulations, certain trusts in existence on August 20, 1996 which
        are
        eligible to be treated as U.S. persons).

       

      9.           That
        the Investor agrees to such amendments of the Pooling and Servicing Agreement
        dated as of [__________] 1, 200[   ] between Citicorp Mortgage
        Securities, Inc., CitiMortgage, Inc., and [Trustee] [and Paying Agent] (the
        “Pooling and Servicing Agreement”) as may be required to further effectuate the
        restrictions on transfer of the residual certificates to such a “disqualified
        organization,” an agent thereof, an “ERISA Prohibited holder” or a person that
        does not satisfy the requirements of paragraphs 4, 5, 6 and 8.

       

      10.           That
        the Investor consents to the irrevocable designation of CMSI as its agent
        to act
        as “tax matters person” of the REMIC pursuant to the Pooling and Servicing
        Agreement, and if such designation is not permitted by the Internal Revenue
        Code
        and applicable law, to act as tax matters person if requested to do
        so.

       

      11.           Check
        one of the following:

      [_]           The
        Investor has computed any consideration paid to it to acquire the residual
        certificates in accordance U.S. Treasury Regulations Sections 1.860E-1(c)(7)
        by
        computing present values using a discount rate equal to the short-term Federal
        rate prescribed by Section 1274(d) of the Code, compounded based on the period
        selected by the Investor.

      [_]           The
        transfer of the residual certificates complies with U.S. Treasury Regulations
        Section 1.860E-1(c)(5) and, accordingly,

      (i)           the
        Investor is an “eligible corporation,” as defined in U.S. Treasury Regulations
        Section 1.860E-1(c)(6)(i), as to which income from the residual certificates
        will only be taxed in the United States;

      (ii)           at
        the time of the transfer, and at the close of the Investor's two fiscal years
        preceding the year of the transfer, the Investor had gross assets for financial
        reporting purposes (excluding any obligation of a person related to the Investor
        within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii),)
        in
        excess of $100 million and net assets in excess of $10 million;

      (iii)           the
        Investor will transfer the residual certificates only to another “eligible
        corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i),
        in a transaction that satisfies the requirements of Sections 1.860E-1(c)(4)(i),
        (ii) and (iii) and 1.860E-1(c)(5); and

      (iv)           the
        Investor determined the consideration paid to it to acquire the residual
        certificates based on reasonable market assumptions (including, but not limited
        to, borrowing and investment rates, prepayment and loss assumptions, expense
        and
        reinvestment assumptions, tax rates and other factors specific to the Investor)
        that it has determined in good faith.

      [_]           None
        of the above.

      CERTIFICATES
        GOVERNED BY POOLING AGREEMENT

       

      The

        rights, limitations (including restrictions on transfer), duties and immunities
        of CMSI, the Trustee and the holders of the certificates, specifies how amounts
        of interest and principal distributable on the classes of certificates are
        calculated and when such amounts are payable, sets forth the relative priorities
        of the classes of certificates to payments and to allocation of losses, and
        sets
        forth the terms upon which the certificates are to be authenticated and
        delivered, and other matters relevant to an investment in certificates. Holders
        may obtain a copy of the Pooling Agreement (without exhibits) from the
        Trustee.

      CERTIFICATES
        GOVERNED BY POOLING AGREEMENT

       

      The
        certificates are issued pursuant to the Pooling Agreement, which states the
        rights, limitations (including restrictions on transfer), duties and immunities
        of CMSI, the Trustee and the holders of the certificates, specifies how amounts
        of interest and principal distributable on the classes of certificates are
        calculated and when such amounts are payable, sets forth the relative priorities
        of the classes of certificates to payments and to allocation of losses, and
        sets
        forth the terms upon which the certificates are to be authenticated and
        delivered, and other matters relevant to an investment in certificates. Holders
        may obtain a copy of the Pooling Agreement (without exhibits) from the
        Trustee.

       

       

      OPTIONAL
        EARLY TERMINATION

       

      This
        certificate may receive a final distribution of all amounts owing in respect
        of
        the class represented by this certificate before its last scheduled distribution
        day if CMSI (or its assignee) exercises its right under the Pooling Agreement
        to
        repurchase all of the mortgage loans in the Trust Fund. This right cannot
        be
        exercised until the aggregate scheduled principal balance of such mortgage
        loans
        is less than 10% of the aggregate scheduled principal balance of the mortgage
        loans as of the cut-off date.

      CERTIFICATES
        GOVERNED BY POOLING AGREEMENT

       

      The
        certificates are issued pursuant to the Pooling Agreement, which states the
        rights, limitations (including restrictions on transfer), duties and immunities
        of CMSI, the Trustee and the holders of the certificates, specifies how amounts
        of interest and principal distributable on the classes of certificates are
        calculated and when such amounts are payable, sets forth the relative priorities
        of the classes of certificates to payments and to allocation of losses, and
        sets
        forth the terms upon which the certificates are to be authenticated and
        delivered, and other matters relevant to an investment in certificates. Holders
        may obtain a copy of the Pooling Agreement (without exhibits) from the
        Trustee.

        certificate may receive a final distribution of all amounts owing in respect
        of
        the class represented by this certificate before its last scheduled distribution
        day if CMSI (or its assignee) exercises its right under the Pooling Agreement
        to
        repurchase all of the mortgage loans in the Trust Fund. This right cannot
        be
        exercised until the aggregate scheduled principal balance of such mortgage
        loans
        is less than 10% of the aggregate scheduled principal balance of the mortgage
        loans as of the cut-off date.

                  Internal Revenue Code of 1986, as amended (the “Code”) or any Governmental

                  state
                  or local law which is, to a material extent, similar to the foregoing
                  provisions of ERISA or the Code (collectively, a “Plan”) or any person
                  investing the assets of a Plan except as provided in section 5.2
                  of the
                  Pooling Agreement referred to below.

                Transfer
                  of this certificate is restricted as set forth in section 5.2 of
                  the
                  Pooling Agreement. As a condition of ownership of this certificate,
                  a
                  transferee must furnish an affidavit to the transferor and the
                  Trustee
                  that (a) it is not a “disqualified organization,” as defined in Section
                  860e(e)(5) of the Code, (b) it is not acquiring this certificate
                  as an
                  agent (including a broker, nominee or other middleman) on behalf
                  of a
                  disqualified organization, (c) it understands that it may incur
                  tax
                  liabilities in excess of cash flows generated by the residual interest
                  and
                  it intends to pay taxes associated with holding the residual interest
                  as
                  they become due, (d) it historically has paid its debts as they
                  have come
                  due and intends to pay its debts as they come due in the future,
                  (e) it
                  will not cause the income with respect to this certificate to be
                  attributable to a foreign permanent establishment or fixed base,
                  within
                  the meaning of an applicable income tax treaty, of it or any other
                  person,
                  and (f) it is not a “Non-permitted Foreign holder,” as defined in section
                  5.2 of the Pooling Agreement. By accepting this certificate, a
                  transferee
                  will be subject to such restrictions on transferability, and will
                  have
                  consented to any amendments to the Pooling Agreement that are required
                  to

                ensure
                  that this certificate is not transferred to a disqualified organization
                  or
                  its agent, or to a Non-permitted Foreign holder. To satisfy a regulatory
                  safe harbor against the disregard of such transfer, the transferor
                  may be
                  required to conduct a reasonable investigation of the financial
                  condition
                  of the transferee and either transfer this certificate at a specified
                  minimum price or transfer this certificate to an eligible
                  transferee.

                Neither
                  this certificate nor the underlying mortgage loans are insured
                  or

      CERTIFICATES
        GOVERNED BY POOLING AGREEMENT

       

      The
        certificates are issued pursuant to the Pooling Agreement, which states the
        rights, limitations (including restrictions on transfer), duties and immunities
        of CMSI, the Trustee and the holders of the certificates, specifies how amounts
        of interest and principal distributable on the classes of certificates are
        calculated and when such amounts are payable, sets forth the relative priorities
        of the classes of certificates to payments and to allocation of losses, and
        sets
        forth the terms upon which the certificates are to be authenticated and
        delivered, and other matters relevant to an investment in certificates. Holders
        may obtain a copy of the Pooling Agreement (without exhibits) from the

“upper-tier REMIC,” “lower-tier REMIC,” and the “pooling REMIC,” respectively).
        This class [PR][LR] [R] certificate represents the “residual interest” in the
        [pooling][lower-tier] [upper-tier] REMIC within the meaning of Code Section
        860G(a)(2).  As a condition of ownership of this certificate, the

        the
        status of any of the [**] segregated asset pools comprising the Trust Fund
        as a
        REMIC.

       

      The
        holder further agrees to the designation of the Servicer as its agent to
        act as
“tax matters person” for purposes of Subchapter C of Chapter 63 of Subtitle F of
        the Code or, if requested by the Servicer, to act as tax matters
        person.

        the Trustee and CMSI.

       

      3      Duties
        of Custodian

      As
        Custodian, Citibank will have all of the rights and obligations of the Mortgage
        Document Custodian and Mortgage Note Custodian set forth in the Pooling
        Agreement, including but not limited to the following:

      (a)        Safekeeping.
        Citibank will

      ·      identify
        each mortgage note by loan number, address of mortgaged property, and name
        of
        mortgagor,

      ·      maintain
        the mortgage note in secure and fire resistant facilities in accordance with
        customary standards for such custody,

      ·      identify
        the mortgage note as being held and to hold the mortgage note for and on
        behalf
        of the Trustee for the benefit of all present and future certificate
        holders,

      ·      maintain
        accurate records pertaining to mortgage notes as will enable the Trustee
        to
        comply with the terms and conditions of the Pooling Agreement, and

      ·      maintain
        at all times a current inventory and conduct periodic physical inspections
        of
        the mortgage notes in such a manner as will enable the Trustee and CitiMortgage
        to verify the accuracy of Citibank’s record-keeping, inventory and physical
        possession.

      Citibank
        will promptly report to the Trustee and CitiMortgage any failure on its part
        to
        hold the mortgage notes as provided in this agreement or the Pooling Agreement
        and will promptly take appropriate action to remedy any such
        failure.

      (b)        Release
        of mortgage notes. Citibank is authorized, upon receipt of a direction from
        the Trustee pursuant to section 3.13, “Release of mortgage files,” of the
        Pooling Agreement, to release to CitiMortgage or its designee, as directed,
        the
        mortgage notes set forth in such direction.  All mortgage notes so
        released will be held by the recipient in trust for the benefit of the Trustee
        in accordance with the Pooling Agreement.  Such mortgage notes will be
        returned to Citibank when the need therefor in connection with foreclosure
        or
        servicing no longer exists, unless the mortgage loan is liquidated or paid
        in
        full. Citibank is also authorized to release any mortgage note to CMSI after
        purchase by CMSI of the related mortgage loan or the property securing such
        mortgage loan, all as provided in, and subject to the provisions of, the
        Pooling
        Agreement.

      (c)        Review
        of mortgage notes; administration; reports. Citibank will attend to all
        non-discretionary details in connection with maintaining custody of the mortgage
        notes, including reviewing each mortgage note within 90 days after issuance
        of
        the certificates and ascertaining that the mortgage note has been executed
        and
        received, and in connection therewith, delivering, in electronic form, such
        reports and certifications to the Trustee and CMSI as are required by
        the

        Mortgage
          Note Custodial Agreement

      

      [Date]

       

      Pooling
        Agreement. If in the course of such review, or if at any time during the
        term of
        this agreement, Citibank determines that a mortgage note is defective or
        missing, it will promptly so notify, in electronic form, the Trustee and
        CitiMortgage in accordance with the provisions of section 2.3, “Repurchase
        or substitution of mortgage loans,” of the Pooling Agreement, and will, within
        30 days thereafter, provide the Trustee with an updated report certifying
        as to
        the defects or lack of the mortgage note, with any applicable exceptions
        noted
        thereon. Citibank will assist the Trustee and CitiMortgage generally in the
        preparation of reports (including by providing information reasonably requested
        as necessary to such preparation) to certificate holders or to regulatory
        bodies
        to the extent necessitated by Citibank’s custody of the mortgage
        notes.

      (d)        Successor
        trustees. Citibank will, in accordance with section 8.8. “Successor
        trustee,” of the Pooling Agreement, amend this agreement to make a successor
        Trustee the successor to the predecessor Trustee under this
        agreement.

       

      4      Access
        to Records

      Subject
        to section 3(b), upon not less than three days’ notice, Citibank will
        permit the Trustee, CitiMortgage or any Subservicer appointed by CitiMortgage
        or
        their duly authorized representatives, attorneys or auditors to inspect mortgage
        notes and the books and records maintained by Citibank pursuant hereto at
        such
        times as the Trustee, CitiMortgage or any Subservicer may reasonably request,
        subject only to compliance by the Trustee, CitiMortgage or any Subservicer
        with
        the security procedures of Citibank applied by Citibank to its own employees
        having access to these and similar records.

       

      5      Instructions;
        authority to act

      Citibank
        will be deemed to have received proper instructions with respect to the mortgage
        notes upon its receipt of written instructions signed by a Responsible Officer
        of the Trustee or a Servicing Officer of the Servicer. A certified copy of
        a
        resolution of the Board of Directors of the Trustee may be accepted by Citibank
        as conclusive evidence of the authority of any such officer to act and may
        be
        considered as in full force and effect until receipt of written notice to
        the
        contrary by Citibank from the Trustee, CitiMortgage or any Subservicer. Such
        instructions may be general or specific in terms. Citibank may rely upon
        and
        will be protected in acting in good faith upon any such written instructions
        received by it and which it reasonably believes to be genuine and duly
        authorized with respect to all matters pertaining to this agreement and its
        duties hereunder.

       

      6      Indemnification

      (a)        Citibank
        will indemnify the Trustee for any and all liabilities, obligations, losses,
        damages, payments, costs or expenses of any kind whatsoever which may be
        imposed
        on, incurred or asserted against the Trustee as the result of any act or
        omission in any way relating to the maintenance and custody by Citibank of
        the
        mortgage notes; provided, however, that Citibank will not be liable for
        any portion of any such amount resulting from the gross negligence or willful
        misconduct of the Trustee.

          Note Custodial Agreement

      

      [Date]

       

      (b)        CitiMortgage
        will indemnify Citibank and hold it harmless against any loss, liability
        or
        expense incurred without gross negligence or bad faith on Citibank’s part,
        arising out of or in connection with the acceptance or administration of
        the
        trust or trusts created under the Pooling Agreement or Citibank’s custody of the
        mortgage notes, including the costs and expenses of defending itself against
        any
        claim or liability in connection with the exercise or performance of any
        of its
        powers or duties hereunder or under the Pooling Agreement. Such indemnification
        will survive the payment of the certificates and termination of the Trust
        Fund,
        as well as the resignation or removal of CitiMortgage as Servicer (if such
        action which caused the need for the indemnification occurred while CitiMortgage
        acted as Servicer), and for purposes of such indemnification neither the
        negligence nor bad faith of the Trustee will be imputed to, or adversely
        affect,
        the right of Citibank to indemnification.

       

      7      Limitation
        of Custodian’s liabilities and duties

      (a)        Citibank
        will not be responsible for preparing or filing any reports or returns relating
        to federal, state or local income taxes with respect to this agreement, other
        than for Citibank’s compensation or for reimbursement of expenses.

      (b)        Citibank
        will not be responsible or liable for, and makes no representation or warranty
        with respect to, the validity, adequacy or perfection of any lien upon or
        security interest in any mortgage note.

      (c)        Any
        other provision of this agreement to the contrary notwithstanding, Citibank
        will
        have no notice, and will not be bound by any of the terms and conditions
        of any
        other document or agreement executed or delivered in connection with, or
        intended to control any part of, the transactions anticipated by or referred
        to
        in this agreement unless Citibank is a signatory party to that document or
        agreement. Notwithstanding the foregoing sentence, Citibank will be deemed
        to
        have notice of the terms and conditions (including without limitation
        definitions not otherwise set forth in full in this agreement) of other
        documents and agreements executed or delivered in connection with, or intended
        to control any part of, the transactions anticipated by or referred to in
        this
        agreement, to the extent such terms and provisions are referenced, or are
        incorporated by reference, into this agreement only as long as the Trustee
        or
        CitiMortgage will have provided a copy of any such document or agreement
        to
        Citibank.

      (d)        Citibank’s
        rights and obligations will only be such as are expressly set forth in this
        agreement or the Pooling Agreement. In no event will Citibank be obligated
        to
        ascertain or take action except as expressly provided in this agreement or
        the
        Pooling Agreement.

      (e)        Nothing
        in this agreement will be deemed to impose on Citibank any obligation to
        qualify
        to do business in any jurisdiction, other than (i) a jurisdiction where a
        mortgage notes is or may be held by Citibank, and (ii) where failure to
        qualify could have a material adverse effect on Citibank or its property
        or
        business or on the ability of Citibank to perform it duties
        hereunder.

      (f)        Subject
        to section 3, under no circumstances will Citibank be obligated to verify
        the authenticity of any signature on any of the documents received or examined
        by it in connection with this agreement or the authority or capacity of any
        person to execute or issue such document, nor will Citibank be responsible
        for
        the value, form, substance, validity, perfection (other than by

      taking
        and continuing possession of the mortgage notes), priority, effectiveness
        or
        enforceability of any of such documents, nor will Citibank be under a duty
        to
        inspect, review or examine the documents to determine whether they are
        appropriate for the represented purpose or that they have been actually recorded
        or that they are other than what they purport to be on their face.

      (g)        Citibank
        will have no duty to ascertain whether or not any cash amount or payment
        has
        been received by the Trustee, the CMSI or any third person.

      (h)        Citibank
        may assign its rights and obligations under this agreement , in whole or
        in
        part, to any Affiliate; however, Citibank will notify CMSI, CitiMortgage
        and the
        Trustee of any such assignment. Citibank may not assign its rights or
        obligations under this agreement, in whole or in part, to any other entity
        without the prior written consent of CMSI, CitiMortgage and the Trustee,
        which
        consent will not be unreasonably withheld. An “Affiliate” is an entity that
        directly or indirectly controls, is controlled by or is under common control
        with Citibank. Notwithstanding any such assignment, Citibank will remain
        liable
        for all of its obligations under this agreement unless the assignment has
        been
        approved by CMSI, CitiMortgage and the Trustee.

      (i)        Subject
        to section 6, “Indemnification,” neither Citibank nor any of its
        Affiliates, directors, officers, agents, and employees will be liable
        for

      ·      any
        action or omission to act hereunder except for its own or such person’s gross
        negligence, willful misconduct, breach of this agreement or violation of
        applicable law, or

      ·      any
        special, indirect, punitive or consequential damages resulting from any action
        taken or omitted to be taken by it or them hereunder or in connection herewith
        even if advised of the possibility of such damages.

      (j)        Citibank
        will not be required to expend or risk its own funds or otherwise incur any
        financial liability in the performance of any of its duties under this Agreement
        or the Pooling Agreement or in the exercise of any of its rights and
        obligations, if, in its sole judgment, it will believe that repayment of
        such
        funds or adequate indemnity against such risk or liability is not assured
        to
        it.

      (k)        Citibank
        will not be responsible for delays or failures in performance resulting from
        acts beyond its control, such as acts of God, strikes, lockouts, riots, acts
        of
        war or terrorism, epidemics, nationalization, expropriation, currency
        restrictions, governmental regulations superimposed after the fact, fire,
        communication line failures, computer viruses, power failures, earthquakes
        or
        other disasters.

      (l)        Any
        entity into which Citibank may be merged or converted or with which it may
        be
        consolidated, or any entity resulting from any merger, conversion or
        consolidation to which Citibank will be a party, or any entity succeeding
        to the
        business of Citibank, will be the successor of Citibank hereunder, 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.

       

      8      Advice
        of counsel

      Citibank
        may rely and act upon advice of counsel with respect to its performance as
        Custodian, and will not be liable for any action it reasonably takes pursuant
        to
        such advice, provided that such action is not in violation of applicable
        federal
        or state law.

      9      Effective
        period, termination and amendment, and interpretive and additional
        provisions

      This
        agreement may be terminated (a) by Citibank’s resignation as Custodian, or
        (b) by either CitiMortgage or the Trustee. In each case, such termination
        will be effected by notice to the other parties given no less than 60 days
        prior
        to termination. Upon notice of such termination, CitiMortgage will use its
        reasonable best efforts to select a successor Custodian reasonably acceptable
        to
        the Trustee upon substantially the same terms and conditions as set forth
        in
        this agreement. If no such successor Custodian has been selected by the
        50th day
        after such notice, the Trustee may, upon prior notice to CitiMortgage, select
        a
        successor Custodian. If no successor Custodian has been selected by CitiMortgage
        or the Trustee by the effective date of the Citibank’s termination, the Trustee
        will act as successor Custodian until the Trustee and CitiMortgage agree
        on a
        successor Custodian.

      At,
        or as
        soon as practicable after, the termination of this agreement, Citibank will
        deliver the mortgage notes to the successor Custodian at such place as the
        successor Custodian reasonably designates.

       

      10           Binding
        arbitration

      Any
        misunderstanding or dispute between Citibank and CMSI or CitiMortgage arising
        out of this agreement will be settled through consultation and negotiation
        in
        good faith and a spirit of mutual cooperation. However, if these attempts
        fail,
        such misunderstandings or disputes will be decided by binding arbitration
        conducted, upon request by either of them, in New York, New York, before
        a
        single arbitrator designated by the American Arbitration Association (the
        AAA),
        in accordance with the terms of the Commercial Arbitration Rules of the AAA,
        and
        to the maximum extent applicable, the United States Arbitration Act
        (Title 9 of the United States Code). Notwithstanding anything herein to the
        contrary, either Citibank, CMSI or CitiMortgage may proceed to a court of
        competent jurisdiction to obtain equitable relief at any time. An arbitrator
        may
        not award punitive damages or other damages not measured by the prevailing
        party’s actual damages. To the maximum extent practicable, an arbitration
        proceeding under this agreement will be concluded within 180 days of the
        filing
        of the dispute with the AAA. This arbitration clause will survive any
        termination or expiration of this agreement and if any term, covenant, condition
        or provision of this arbitration clause is found to be unlawful, invalid
        or
        unenforceable, the remaining parts of the arbitration clause will not be
        affected thereby and will remain fully enforceable.

       

      11           Governing
        Law

      This
        agreement will be governed by, and construed in accordance with, the laws

      Ladies
        and Gentlemen:

      

      In
        connection with the purchase by us of $_____________________ initial
        principal
        balance of the [Citicorp Mortgage Securities Trust] [CMALT (CitiMortgage
        Alternative Loan Trust)], Series 200[*-*] REMIC Pass-Through Certificates
        class
        B-[4][5][6] certificates, we confirm that:

      

      1.  We
        understand that the class B-[4][5][6] certificates are not being registered
        under the Securities Act of 1933, as amended (the "Securities Act") or any
        state
        securities or "blue sky" laws and are being transferred to us in a transaction
        that is exempt from the registration requirements of the Securities Act and
        any
        such laws.

      

      2.  We
        (check one)

      

      [_]
        have
        such knowledge and experience in financial and business matters as to be
        capable
        of evaluating the merits and risks of investment in the class B-[4][5][6]
        certificates, we are able to bear the economic risk of investment in the
        class
        B-[4][5][6] certificates and we are an accredited investor as defined in
        Regulation D under the Securities Act.  We have such knowledge and
        experience in financial and business matters, specifically in the field of
        mortgage related securities, as to be able to evaluate the risk of purchasing
        a
        certificate which is subordinate in right of payment, and we have direct,
        personal and significant experience in making investments in mortgage related
        securities.  If we are non-institutional investors, our net worth
        (exclusive of our primary residence) is at least $1,000,000.

      

      [_]  are
        "Qualified Institutional Buyers" within the meaning of Rule 144A promulgated
        under the Securities Act.

      

      3.  We
        will acquire the class B-[4][5][6] certificates for our own account or for
        accounts as to which we exercise sole investment discretion and not with
        a view
        to any distribution of the class B-[4][5][6] certificates, subject,
        nevertheless, to the understanding that disposition of our property shall
        at all
        times be and remain within our control.

      

      D-1

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      4.  We
        agree that our class B-[4][5][6] certificates must be held indefinitely by
        us
        unless subsequently registered under the Securities Act and any applicable
        state
        securities or "blue sky" laws or unless exemptions from the registration
        requirements of the Securities Act and such laws are available.

      

      5.  We
        agree that in the event that at some future time we wish to sell, dispose
        of or
        otherwise transfer any of our class B-[4][5][6] certificates, we will not
        transfer any of such class B-[4][5][6] certificates unless:

      

      (A)  (1)
        the transfer is made to an Eligible Purchaser (as defined below), (2) a letter
        to substantially the same effect as this letter is executed promptly by such
        Eligible Purchaser or by an Eligible Dealer (as defined below) on behalf
        of such
        Eligible Purchaser and (3) all offers or solicitations in connection with
        the
        sale (if a sale), whether directly or through any agent on our behalf, are
        limited only to Eligible Purchasers and are not made by means of any form
        of
        general solicitation or general advertising whatsoever; or

      

      (B)  Such
        class  B-[4][5][6] certificates are otherwise sold in a transaction
        that does not require registration under the Securities Act.

      

      "Eligible
        Purchaser" means an Eligible Dealer or a corporation, partnership or other
        entity which we have reasonable grounds to believe and do believe can make
        representations with respect to itself to substantially the same effect as
        the
        representations set forth herein; "Eligible Dealer" means any corporation
        or
        other entity having as a principal business acting as a broker or dealer
        in
        securities.

      

      6.  We
        understand that each of the class B-[4][5][6] certificates will bear a legend
        to
        substantially the following effect:

      

      This
        class B-[4][5][6] certificate is subordinated in right of payments to the
        class
        A, B-1, B-2 [,][and] B-3 [,][and] [B-4] [and B-5] certificates, as described
        in
        the Pooling Agreement referred to herein. This certificate has not been
        registered under the Securities Act of 1933, as amended, and may not be sold,
        or
        offered for sale, transferred or otherwise disposed of unless such sale,
        transfer or other disposition is made pursuant to an effective registration
        statement under such act and any applicable blue sky law or unless an exemption
        under such act and any applicable blue sky law is available.

      

      This
        certificate may not be purchased by or transferred to any person that is
        an
        employee benefit plan subject to Title I of the Employee Retirement Income
        Security Act of 1974, as amended (“ERISA”) or Section 4975 of the Internal
        Revenue Code of 1986, as amended (the “Code”) or any Governmental Plan, as
        defined in Section 3(32) of ERISA, subject to any federal, state or local
        law
        which is, to a material extent, similar to the foregoing provisions of ERISA
        or
        the Code (collectively, a “Plan”) or any person investing the assets of a Plan
        except as provided in section 5.2 of the Pooling Agreement referred to
        herein.
