      is
      between CitiMortgage, Inc. ("CMI" or the "Seller") and Citicorp Mortgage
      Securities, Inc., a Delaware corporation ("CMSI").  The Seller agrees
      to sell, and CMSI agrees to purchase, the mortgage loans originated or acquired
      by CMI as described and set forth in the Mortgage Loan Schedule attached as
      exhibit B (the "mortgage loans") to the Pooling and Servicing Agreement dated

      of June 1, 2007 (the "Pooling Agreement"), between CMSI, CMI, U.S. Bank National
      Association, a national banking association, in its individual capacity and
      as
      Trustee (the "Trustee"), and Citibank, N.A., in its individual capacity and
      as
      Paying Agent, Certificate Registrar and Authentication Agent, relating to the
      issuance of Citicorp Mortgage Securities Trust, Series 2007-5 REMIC Pass-Through
      Certificates class A, class B and residual certificates.  Terms used
      without definition herein shall have the respective meanings assigned to them
      in
      the Pooling Agreement or, if not defined therein, in the Senior Underwriting
      Agreement dated May 24, 2007 among CMSI, Citigroup Inc. and Citigroup Global
      Markets Inc. (the "Senior Underwriter") (the "Senior Underwriting Agreement")
      and in the Subordinated Underwriting Agreement dated June 20, 2007 among CMSI,
      Citigroup Inc. and UBS Securities LLC (the "Subordinated Underwriter" and,
      together with the Senior Underwriter, the "Underwriters") (the "Subordinated
      Underwriting Agreement" and, together with the Senior Underwriting Agreement,
      the "Underwriting Agreements").

    

    1.      Purchase
      Price.  The purchase price (the "Purchase Price") for the mortgage
      loans shall consist of (a) cash in the amount of _____________% of the aggregate
      scheduled principal balance thereof as of the cut-off date, plus accrued
      interest thereon at the rate of 6.00% per annum on the mortgage loans in pool
      I
      and 5.50% per annum on the mortgage loans in pool II and pool III, from and
      including the cut-off date to but excluding the closing date, (b) the class
      IA-IO, IIA-IO and IIIA-IO certificates, (c) the class LR certificates and (d)
      the class PR certificates.  Such cash shall be payable by CMSI to the
      Seller on the closing date in same-day funds, and the Seller will receive on
      the
      closing date: (a) the class IA-IO, IIA-IO and IIIA-IO certificates and (b)
      the
      class LR and class PR certificates evidencing the residual interests in the
      lower-tier REMIC and the pooling REMIC, respectively.  If CMSI for any
      reason shall repay to any Underwriter any portion of the price paid to CMSI
      by
      any Underwriter pursuant to the Underwriting Agreements, the Seller shall
      simultaneously and in the same manner repay to CMSI a proportionate amount
      of
      the Purchase Price as such repayment to any Underwriter.

    

    Upon
      payment of the Purchase Price, the Seller shall transfer, assign, set over
      and
      otherwise convey to CMSI without recourse all of the Seller's right, title
      and
      interest in and to the mortgage loans, including all interest and principal
      received or receivable by the Seller on or with respect to the mortgage loans
      (other than payments of principal and interest due and payable on the mortgage
      loans on or before the cut-off date and prepayments of principal on the mortgage
      loans received or posted prior to the close of business on the cut-off date),
      together with all of the Seller's right, title and interest in and to the
      proceeds of any related title, hazard or other insurance policies and Primary
      Mortgage Insurance Certificates.  The Seller agrees to deliver to CMSI
      all documents, instruments and agreements required to be delivered by CMSI
      to
      the Trustee under the Pooling Agreement and such other documents, instruments
      and agreements as CMSI shall reasonably request.  CMSI hereby directs
      the Seller to execute and deliver to the Trustee assignments of the Mortgages
      to
      the Trustee (and endorsements of any Mortgage Notes relating thereto) in
      recordable form.  Such

    
      
         

      

      
        1

        
          

        

      

      
         

      

    

    assignments
      and endorsements shall not affect the rights of the parties hereto or to the
      Pooling Agreement.

    

    2.      Representations.  The
      Seller hereby represents and warrants to CMSI (i) that CMSI's representations
      and warranties pursuant to the Pooling Agreement to the Trustee with respect
      to
      the mortgage loans are true and correct and (ii) that the Seller has not dealt
      with any broker, investment banker, agent or other person (other than CMSI
      and
      the Underwriters) who may be entitled to any commission or compensation in
      connection with the sale of the related mortgage loans.  The Seller
      hereby agrees to cure any breach of such representations and warranties in
      accordance with the terms of the Pooling Agreement.

    

    3.      Underwriting.  The
      Seller hereby agrees to furnish any and all information, documents,
      certificates, letters or opinions reasonably requested by CMSI in order to
      perform any of its obligations or satisfy any of the conditions on its part
      to
      be performed or satisfied at or prior to the closing date.

    

    4.      Costs.  CMSI
      shall pay all expenses incidental to the performance of its obligations under
      the Underwriting Agreements, including without limitation (i) any recording
      fees
      or fees for title policy endorsements and continuations, (ii) the expenses
      of
      preparing, printing and reproducing the Registration Statement, the Prospectus,
      the Underwriting Agreements, the Pooling Agreement and the certificates and
      (iii) the cost of delivering the certificates to the offices of The Depository
      Trust Company or the Underwriters, as the case may be.

    

    5.      Indemnification.  The
      Seller hereby agrees to indemnify, defend and hold harmless CMSI against any
      and
      all losses, claims, damages or liabilities (i) resulting from the Seller's
      failure to perform any of its obligations hereunder, (ii) resulting from the
      inaccuracy of the Seller's representations and warranties herein or of CMSI's
      representations and warranties in the Pooling Agreement or (iii) insofar as
      such
      losses, claims, damages or liabilities (or actions or demands for reimbursement
      or contribution in respect thereof) arise out of or are based upon information
      relating to the Seller or the mortgage loans pursuant to the Underwriting
      Agreements.

    

    6.      Purchase
      and Sale; Security Interest.  The parties hereto intend the
      conveyance by the Seller to CMSI of all of its right, title and interest in
      and
      to the mortgage loans pursuant to this Agreement to constitute a purchase and
      sale and not a loan. Notwithstanding the foregoing, to the extent that such
      conveyance is held not to constitute a sale under applicable law, it is intended
      that this Agreement shall constitute a security agreement under applicable
      law
      and that the Seller shall be deemed to have granted to CMSI a first priority
      security interest in all of the Seller's right, title and interest in and to
      the
      mortgage loans.

    

    7.      Notices.  All
      demands, notices and communications hereunder shall be in writing, shall be
      effective only upon receipt and shall, if sent to CMSI be addressed to it at
      1000 Technology Drive, O’Fallon, Missouri 63368, Attn: Daniel P. Hoffman or if
      sent to Seller be addressed to it at 1000 Technology Drive, O’Fallon, Missouri
      63368, Attn: General Counsel.

    

    8.      Trustee
      Beneficiary.  The representations and agreements made by the
      Seller in this Agreement are made for the benefit of, and may be enforced by,
      the Trustee, and the holders of certificates to the same extent that the Trustee
      and the holders of certificates, respectively, have rights against CMSI under
      the Pooling Agreement in respect of representations and agreements made by
      CMSI
      therein.

    9.      Cross-Receipt.  The
      Seller, by executing this Agreement below, hereby acknowledges receipt of the
      Purchase Price from CMSI.  CMSI, by executing this Agreement below,
      hereby acknowledges receipt of the Mortgage Loans from the Seller.

    

    10.           Miscellaneous.  This
      Agreement shall be governed by and construed in accordance with the laws of
      the
      State of New York.  Neither this Agreement nor any term hereof may be
      changed, waived, discharged or terminated except by a writing signed by the
      party against whom enforcement of such change, waiver, discharge or termination
      is sought.  This Agreement may not be changed in any manner which
      would have a material adverse affect on holders of any class of certificates
      without the prior written consent of the Trustee.  The Trustee shall
      be protected in consenting to any such change to the same extent provided in
      section 10 of the Pooling Agreement. This Agreement may be signed in any number
      of counterparts, each of which shall be deemed an original, which taken together
      shall constitute one and the same instrument.  This Agreement shall
      bind and inure to the benefit of and be enforceable by CMSI and the Seller
      and
      their respective successors and assigns; provided, however, that
      this Agreement cannot be assigned by either party without the consent of the
      other party hereto, and any assignment hereof without such consent shall be
      void.

        the class B-1 through B-3 certificates will be issued as book-entry
        certificates. Book-entry certificates for a class or a group of classes
        will be represented by one or more certificates issued in the name of a
        depository. The ratio-stripped IO certificates, the class B-4 through B-6
        certificates, and the residual certificates will be issued in fully registered
        certificated form (definitive certificates).

Voting
        interests

      Each

        class will have a 1% voting interest. The remaining voting interest
        will be allocated to the other classes in proportion to their principal
        balances. The voting interest of any class will be allocated among the
        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
        and
        the Insurer is not in default.

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 distribution day, as described in
        “Adjustments to class balances” below.

      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
        for classes” above.

Certificate

      The
        sum
        of the initial principal or notional balances stated on the certificates
        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.

        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

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

        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.)

       

      14.2
Principal
        allocations

      The
        principal allocation for a distribution day is:

      (a)
        for any ratio-stripped PO class, the sum for that distribution day of scheduled
        and unscheduled principal payments on its PO strip for that distribution
        day.

      (b)
        for the senior target-rate classes collectively, the
        sum for that distribution day of

      ·      the
        target-rate class percentage for the senior target-rate classes of scheduled
        principal payments on the target-rate strip, and

      ·      all
        unscheduled principal payments on the target-rate strip allocated to the
        senior
        target-rate classes pursuant to “ – Unscheduled principal” below.

      The
        principal allocation for the senior target-rate classes will be allocated
        among
        the individual senior target-rate classes pursuant to “Allocations among the
        senior classes” below.

      (c)

      ·      the
        class’s target-rate class percentage of scheduled principal payments on the
        target-rate strip for that distribution day,

      ·      plus
        the class’s proportionate share, based on the principal balances of the
        subordinated classes, of unscheduled principal payments on the target-rate
        strip

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.

        classes

      Classes
        IA-3 and IA-22 are non-accelerated senior, or NAS,
        classes.

      For
        the
        first 60 distribution days, the principal allocation for a NAS class will
        be
        zero.

      For
        distribution day 61 and after, the principal allocation for each NAS class
        will
        equal

      ·      its
        proportionate share, based on the principal balances of the group’s target-rate
        classes, of scheduled principal payments on the related pool’s target-rate strip
        allocated to the group’s target-rate classes for that distribution day,
        plus

      ·      the
        following percentage of its proportionate share, based on principal balances
        of
        the group‘s target-rate classes, of unscheduled principal payments on the
        related pool’s target-rate strip allocated to the group’s target-rate classes

      While
        an
        accrual class may receive principal distributions prior to the subordination
        depletion date, an accrual class will not receive current interest distributions
        prior to the earlier of its accrual termination day or the subordination
        depletion date.

      On
        each
        such prior distribution day, before interest is distributed to the accrual
        classes IA-17, IA-18 and IA-21,

      first,
        interest that is accrued on the principal balance of the accrual class IA-18
        will be redirected to make principal payments on the accrual directed class
        IA-16 until its principal balance is reduced to its targeted balance for
        that
        distribution day, and any remaining interest on class IA-18 will be redirected
        sequentially to make principal payments on accrual directed classes IA-17
        and
        IA-16, in that order;

      second,
        interest that is accrued on the principal balance of the accrual class IA-17
        will be redirected to make principal payments on the accrual directed class
        IA-16 until its principal balance is reduced to its targeted balance for
        that
        distribution date, and any remaining interest on class IA-17 will be redirected
        to class IA-17 itself; and

      third,
        interest that is accrued on the principal balance of the accrual class IA-21
        will be redirected to make principal payments to the accrual directed class
        IA-20 until its principal balance is reduced to zero.

      If
        on a
        distribution day before an accrual class’s accrual termination day, the accrual
        class’s interest distribution exceeds the aggregate principal balances of its
        accrual directed classes, then

      ·      only
        that portion of the accrual class’s interest distribution that equals the
        aggregate principal balances of its accrual directed classes will be redirected
        to the accrual directed classes, and

      ·      the
        excess will be distributed as principal to the accrual class
        itself.

      If
        interest distributions on multiple accrual classes are directed to the same
        accrual directed classes, then on the last distribution day before those
        accrual
        classes’ accrual termination day, the redirected portion of the interest
        distribution for each such accrual class will be in proportion to the principal
        balances of such accrual classes on the day before the distribution
        day.

       

      16.3
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

      
        
           

        

        
          19

          
            

          

        

        
           

        

      

      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.

      (5) To
        each class, in order of seniority, a reimbursement of any reduction to 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
        principal balance of a more senior class would be reduced by any part of
        the
        principal portion of a realized subordinated loss.

Distributions
        to
        certificate holders

      On
        each
        distribution day, distributions to a class will be distributed to the holders
        of
        the certificates of the class in proportion to the principal or notional
        balances of their certificates.

        certificates, and if there are no class PR certificates, the LR certificates
        will receive all amounts remaining in the certificate account and in any
        retail
        reserve fund after all required distributions on the
        certificates,

Wire
        transfer
        eligibility

      The
        minimum number of single certificates eligible for wire transfer on each
        distribution day, for the certificates, is 1,000 (representing a $1,000,000
        initial principal balance or initial notional balance) and, for the residual
        certificates, a 100% percentage interest.

                Adjustments
                  to class balances

              

      

      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

      
        
           

        

        
          21

          
            

          

        

        
           

        

      

      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

      ·      references
        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.

       

      
        	18	
                Loss
                  recoveries

              

      

      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.

      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
        preceding provisions for allocations and distributions, and for adjustments
        to
        class balances, are subject to the following sections on LIBOR classes,
        composite and component classes, multiple-pool series, retail classes, and
        insured classes.

      Classes
        IA-1 and IA-2 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 –
General terms for classes” above.

      CitiMortgage
        will determine LIBOR for each LIBOR accrual period (after the first
        LIBOR accrual period) on the second business day before the beginning of
        each
        LIBOR accrual period as follows:

      ·      LIBOR
        for any determination day will be the British Bankers Association LIBOR rate
        for
        US dollar deposits with a one-month maturity at 11AM, London time on that
        day,
        as such rate appears on Telerate Page 3750, Bloomberg Page BBAM, or another page
        of these or any other financial reporting service in general use in the
        financial services industry, rounded upward, if necessary, to the nearest
        multiple of 1/16 of 1%.

      ·      If
        no rate is so reported on that day, CitiMortgage will determine LIBOR on
        the
        basis of the rates on that day at approximately 11AM, London time, at which
        deposits in U.S. Dollars with a maturity of one month in a principal amount
        of
        not less than U.S. $1 million and representative for a single transaction
        in
        that market at that time, are offered to prime banks in the London interbank
        market for at least four major banks in the London interbank market selected
        by
        CitiMortgage. CitiMortgage will request the principal London office of each
        such
        bank to provide a quotation of its rate. If at least two such quotations
        are
        provided, LIBOR will be the arithmetic mean of those quotations.

      ·      If
        fewer than two quotations are provided, LIBOR will be the arithmetic mean
        of the
        rates quoted at approximately 11AM, New York time, on that day by three major
        banks in New York City selected by CitiMortgage for loans in U.S. Dollars
        to
        leading European banks having a maturity of one month in a principal amount
        of
        not less than U.S. $1 million that is representative for a single transaction
        in

      such
        market at such time. If the banks selected by CitiMortgage are not quoting
        such
        rates, LIBOR will be LIBOR for the preceding LIBOR accrual period.

      CitiMortgage
        may designate an affiliate or a third party to determine LIBOR.

                Composite
                  and component classes

              

      

      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.

                Multiple-pool
                  series

              

      

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

      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.

       

      22.1
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

      
        
           

        

        
          23

          
            

          

        

        
           

        

      

      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;

      ·      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.

      
        
           

        

        
          24

          
            

          

        

        
           

        

      

      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

      
        
           

        

        
          25

          
            

          

        

        
           

        

      

      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 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 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.

        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.

        losses, for that day, on class IA-1, and

      For
        each
        distribution day, and for each pool x and y, a

        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

      On

        interest distribution at its certificate rate, 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

      (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.

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 which
        a
        tax matters partner may be designated under applicable Treasury Regulations,
        including Treas­ury Regulations § 1.860F-4(d) and tem­porary
        Treasury Regulations § 301.­6231­(a)­(7)-1T.

      28.1
Yield
        maintenance
        agreement

      Class
        IA-1 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 Bank of
        New York, (the yield maintenance provider) in substantially the form
        attached as exhibit F. The yield

      
        
           

        

        
          32

          
            

          

        

        
           

        

      

      maintenance
        agreement is an asset of the Trust, but not of any constituent
        REMIC.

      Payments
        to the yield maintenance provider will be made by HSBC, 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

              
	
                IA-1

              	
                5.4%

              	
                3.5%

              

      

       

      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 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

      
        
           

        

        
          33

          
            

          

        

        
           

        

      

      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 (i) to cover any such shortfall,
        and (ii) for a distribution day after August 2010, to pay the yield
        maintenance amount.

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

      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 Greenwich Capital, 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 HSBC 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, and

      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, and

      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

        constituent REMIC designated as such in “REMIC provisions” above, and for
        residual certificates, all residual certificates having the same class

        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
        and
        letter pair, then such class follows the class with the same integer x
        and precedes the class of the next greater integer y. Example:
“classes A-3 through A-5” means, if there are classes A-4A and A-4B, each of
        classes A-3, A-4, A-4A, A-4B, and A-5.

      classes

        Agency: An organization registered as a “clearing agency” pursuant to
        Section 17A of the Exchange Act. The initial Clearing Agency will be The

      Clearing
        Agency Participant: A broker, dealer, bank other financial institution or
        other person for whom a Clearing Agency effects book-entry transfers and
        pledges
        of securities deposited with the Clearing Agency.

      collected
        servicing fee on a mortgage loan: For any month, the excess of the interest
        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

      
        
           

        

        
          38

          
            

          

        

        
           

        

      

      ·      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.

      delegated
        servicer: A person or persons, including a special servicer, to whom
        CitiMortgage delegates some or all of its servicing obligations pursuant
        to
        section 4.5.

        company or companies (which may be the Trustee or which may be Citibank,

        account, escrow account, custodial account for P&I and servicing account are
        established or maintained pursuant to section 3.2, 3.3 or 3.3. Each Depository

                  a third-party mortgage loan, the sum of the third-party servicing

      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.)

        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.

        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

        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.

      realized
        losses: For a distribution day, liquidated loan losses (including special

        equal the interest and principal portions of the liquidated loan
        loss.

      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
        or any
        payments on any other assets

      
        
           

        

        
          53

          
            

          

        

        
           

        

      

      included
        in a Trust Fund, the rules set forth in this section 1.2 will be
        applied.

      (b)        Calculations

        issuance of certificates; repurchase and substitution

       

      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 BBB, or is not rated, by Fitch if Fitch is a rating
                  agency,

              

      

      
        	
                ·

              	
                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 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

        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
        of
        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.

      
        
           

        

        
          56

          
            

          

        

        
           

        

      

      (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 11 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 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

      
        
           

        

        
          57

          
            

          

        

        
           

        

      

      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,
        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,

        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

      
        
           

        

        
          58

          
            

          

        

        
           

        

      

      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 to 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,
        all
        applicable usury, equal credit opportunity, recording, disclosure and predatory

      and
        no
        mortgage loan originated on or after October 1, 2002 through March 6, 2003
        is
        governed by the Georgia Fair Lending Act;

      (x)
        A
        lender’s title insurance policy or binder approved as such by Fannie Mae or
        Freddie Mac, or other assurance of title customary in the relevant jurisdiction,
        was issued on the date of the origination of each mortgage loan (other than
        a
        mortgage loan for a cooperative apartment), and, as of the closing date,
        each
        such policy, binder or assurance is valid and in full force and
        effect;

      (xi)
        The
        mortgage loans conform in all material respects with their descriptions in
        the
        prospectus relating to the certificates;

      (xii)
        Each mortgage loan with an original principal balance exceeding 80% (or,
        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

        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 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 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

      
        
           

        

        
          61

          
            

          

        

        
           

        

      

      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 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.

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

      
        
           

        

        
          62

          
            

          

        

        
           

        

      

      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, 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

      
        
           

        

        
          63

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          64

          
            

          

        

        
           

        

      

      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.

      CitiMortgage
        need not deposit in the certificate account

      
        	
                ·

              	
                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 property protection expenses,

              

      

      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

      
        
           

        

        
          65

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          66

          
            

          

        

        
           

        

      

      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 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 and insurance premiums and other similar
        payments relating to the third-party mortgage loans that are not timely paid
        by
        the mortgagors or advanced by the third-party servicers on the date when
        such
        tax, premium or other cost for which such 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

      
        
           

        

        
          67

          
            

          

        

        
           

        

      

      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 an apparent remittance delinquency
        that
        is determined by CitiMortgage to be the result of the occurrence of an
        extraordinary event (but not including a 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
        non-required interest payments to interest at the pass-through rate, and
        (iii) the amount of any uncommitted cash transferred to the distribution
        account for the preceding distribution day, minus

      ·      the
        sum of (i) uncommitted cash transferred to the distribution account on the
        same day pursuant to paragraph (d) above, and (ii) any third-party servicer
        advances for that distribution day.

      (f)
        Paying agent advances. Before noon on each distribution day, the Paying
        Agent will deposit into the distribution account an affiliated Paying Agent
        advance equal to

      ·      the
        sum of (i) all remittance delinquencies on the affiliated mortgage loans
        for that distribution day, and (ii) the amount of all uncommitted cash
        advances related to the affiliated mortgage loans transferred to the
        distribution account for the preceding distribution day,
minus

      ·      the
        sum of (i) any uncommitted cash advance related to the affiliated
        mortgage

      
        
           

        

        
          68

          
            

          

        

        
           

        

      

      loans
        for
        that distribution day and (ii) any voluntary advance by CitiMortgage
        related to the affiliated loans for that distribution day, other than an
        advance
        of interest not required to be paid because of the limitations on mortgage
        interest payments under the federal Servicemembers Civil Relief Act or any
        comparable state laws (Relieved interest).

      Before
        noon on each distribution day, the Paying Agent will deposit into the
        distribution account a third-party Paying Agent advance equal
        to

      ·      the
        sum of (i) all remittance delinquencies on the third-party mortgage loans
        for that distribution day, and (ii) the amount of uncommitted cash advances
        related to the third-party mortgage loans transferred to the distribution
        account for the preceding distribution day, minus

      ·      the
        sum of (i) any uncommitted cash advances related to third-party mortgage
        loans for that distribution day, and (ii) any third-party servicer advance,
        other than an advance of Relieved interest, for that distribution
        day.

      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

      
        
           

        

        
          69

          
            

          

        

        
           

        

      

      Agent
        will not have any obligation to advance such payments.

       

      3.6
        Distributions

      (a)
        Transfers to distribution account. Not later than 12 noon on each
        distribution day, CitiMortgage will withdraw from the certificate account
        and
        deposit in a distribution account established by the Paying Agent (or
        to the extent provided in the Series Terms, any pooling, lower-tier or
        upper-tier REMIC account), all distributions to be made on the distribution
        day
        on the certificates (or class P or class L regular interests). The distribution
        account will be an Eligible Account, and will not be commingled with any
        other
        account.

      (b)
        Distributions to certificate holders. On each distribution day, the
        Paying Agent will distribute from the distribution account (or, to the extent
        provided in the Series Terms, any pooling, lower-tier, or upper-tier REMIC
        account) to each certificate holder of record on the preceding record date
        (other than as provided in section (c) below for final distributions) the
        certificate holder’s share (based on the denomination of certificates of the
        applicable class held by the holder) of the amounts distributable to such
        class
        in accordance with the priorities set forth in the Series Terms, as set forth
        in
        the applicable distribution day statement.

      All
        reductions in principal balance of a certificate (or one or more Predecessor
        Certificates) effected by distributions made on any distribution day or
        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
        at
        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

      ·      if
        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

              

      

      
        
           

        

        
          70

          
            

          

        

        
           

        

      

      wiring
        instructions from the certificate holder, or

      
        	
                ·

              	
                by
                  such other means of payment as the certificate holder, CitiMortgage,
                  and
                  the Paying Agent may agree.

              

      

      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 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;

      ·      the
        principal allocation for each class;

      ·      the
        principal distribution for each class;

      ·      any
        ratio-stripped PO class reimbursement;

      ·      any
        insurance premium; and

        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),
                  and

              

      

      
        	
                ·

              	
                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,

              

      

      then
        CitiMortgage will withdraw any cash balance remaining in the certificate
        account, and apply it in the following order:

      First,
        to the payment to CitiMortgage of any portion of the servicing fee not already
        retained pursuant to section 3.8(b); and

      Second,
        as a distribution to the holders of any class PR, and if there are no class
        PR
        certificates, to the holders of the class LR certificates.

      (i)
        Transfer of certificates. Subject to the foregoing provisions of this
        section 3.6, each certificate delivered under this agreement upon registration
        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.

       

      3.7
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

      
        
           

        

        
          72

          
            

          

        

        
           

        

      

      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.

      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) any amounts
        due
        CitiMortgage under section 3.12 relating to deficiency actions, and (C) any
        excess of the liquidation proceeds after such reimbursement 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

      
        
           

        

        
          73

          
            

          

        

        
           

        

      

      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;

      (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);

      (viii)
        payments to itself or the holders of the residual certificates of Investment
        Income;

      (ix)
        transfers to the distribution account;

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

      (xi)
        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

      
        
           

        

        
          74

          
            

          

        

        
           

        

      

      section
        8.5, “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.

      CitiMortgage
        may maintain a blanket hazard insurance policy on all of the mortgage loans.
        However, if the blanket

      
        
           

        

        
          75

          
            

          

        

        
           

        

      

      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.

      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

      
        
           

        

        
          76

          
            

          

        

        
           

        

      

      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 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,

      
        
           

        

        
          77

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          78

          
            

          

        

        
           

        

      

      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.

          79

          
            

          

        

        
           

        

      

      occurs

Tax
        returns and reports

      (a)
        For
        federal income tax purposes, each constituent REMIC will have a calendar

        thereof, to be bound by this section 3.15 and by section 5.2 and by “REMIC
        Provisions” in the Series Terms.

Application

      On
        or

        the last business day of each month, CitiMortgage will deposit
        in

      
        
           

        

        
          81

          
            

          

        

        
           

        

      

      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

      ·      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; loan modifications

      (a)
        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

      
        
           

        

        
          82

          
            

          

        

        
           

        

      

      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.

      (b)
        CitiMortgage may agree with any homeowner 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).

      Notwithstanding
        the preceding paragraph, CitiMortgage may agree with any homeowner to modify
        or
        waive any provision of a mortgage loan if

      ·      the
        mortgage loan is 90 days or more past due or, in CitiMortgage’s judgment, is
        subject to imminent default, 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.

      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 homeowner’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.

       

      3.19
Investment
        accounts

      (a)
        Investments. CitiMortgage may invest and reinvest funds in an
        investment account in accordance with this section 3.19 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

      
        
           

        

        
          83

          
            

          

        

        
           

        

      

      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, from time to time, withdraw from any investment account (other than
        the
        certificate account), any Investment Income therein, and pay same 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
        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

      
        
           

        

        
          84

          
            

          

        

        
           

        

      

      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

        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

        if S&P is a rating agency, “P-1” by Moody’s if Moody’s is a rating agency,
        and “F-1” by Fitch if Fitch is a rating agency; each such investment being
        expressly authorized and deemed authorized by a certificate holder’s purchase or
        acceptance of any certificate when acting in the capacity of a fiduciary
        (including a “fiduciary” of an “employee benefit plan” subject to ERISA, as
        those term are defined in Sections 3(21) and 3(3) of ERISA, respectively)
        which
        purchase or acceptance will also evidence and be deemed to evidence any such
        certificate holder’s representation and warranty to CitiMortgage, the
        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
        ERISA fiduciary) to give such authorization; and money market funds investing
        exclusively in any of the investments discussed in this definition of Eligible

        if Fitch is a rating agency, and “P-1” by Moody’s if Moody’s is a rating
        agency;

      (iii)          repurchase
        obligations for (A) any security described in clause (i) above or (B) any
        other
        security issued or guaranteed by an 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, in either case where such security
        has a
        remaining maturity of one year or less and where such repurchase obligation
        has
        been entered into with a depository institution or trust company (acting

        rating agency, “P-1” by Moody’s if Moody’s is a rating agency, and “F-1” by
        Fitch if Fitch is a rating agency;

      (iv)          securities
        bearing interest or sold at a discount issued by any corporation incorporated
        under the laws of the United States of America or any state thereof which
        have a
        maturity not greater than 30 days and an unsecured long-term debt rating
        of at
        least “AA” if S&P is a rating agency, “AA” if Fitch is a rating agency, and
“Aa” if Moody’s is a rating agency, or an unsecured short-term debt rating, of
        at least “A-1” if S&P is a rating agency, “F-1” if Fitch is a rating agency,
        and “P-1” if Moody’s is a rating agency, at the time of such investment or
        contractual commitment providing for such investment; provided,
        however, that securities issued by any particular corporation will not be
        Eligible Investments to the extent that investment therein will cause the
        then
        outstanding principal balance of securities issued by such corporation and
        held
        as part of the Trust Fund to exceed 10% of the aggregate current principal
        balance of certificates outstanding and of the current percentage interest
        of
        the residual certificates outstanding, and the aggregate principal balance
        of
        all cash and Eligible Investments, held in the Trust Fund;

      (v)          commercial
        paper (including both non-interest-bearing discount obligations and
        interest-bearing obligations payable on demand or on a specified date not
        more
        than one year after the date of issuance thereof) having at the time of such
        investment a rating of not less than “A-1+” (“A-1” if the maturity is not
        greater than 30 days and such commercial paper does not exceed 20% of the
        then
        current balance of the certificates) by S&P if S&P is a rating agency,
“F-1” by Fitch if Fitch is a rating agency, and “P-1” by Moody’s if Moody’s is a

        agencies or instrumentalities (which obligations are backed by the full faith
        and credit of the United States of America) held by a custodian on behalf
        of the
        holders of such receipts;

      (viii)                  any
        other money market deposit, obligation, security or investment bearing interest
        or sold at a discount which has an unsecured short-term debt rating of at
        least
“A-1+” (“A-1” if the maturity is not greater than 30 days and such investments
        do not exceed 20% of the then scheduled principal balance of the mortgage
        loans)
        if S&P is a rating agency, “F-1” 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
        fund, such fund must be rated in the highest rating category by each rating
        agency (which, for S&P, is “AAAm” or “AAAm-G”); and

      (ix)           any
        other demand or time deposit, obligation, security or investment bearing
        interest or sold at a discount that each rating agency confirms in writing
        is
        acceptable;

      provided,
        that each such Eligible Investment is a “permitted investment” as defined in
        Internal Revenue Code Section 860G(a)(5).

       

      3.20
Paying
        Agent and
        Certificate Registrar

      (a)
        Paying Agent. CitiMortgage or the Trustee may remove a Paying Agent,
        and

      
        
           

        

        
          85

          
            

          

        

        
           

        

      

      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
“F-1” 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.

       

      3.21
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 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),

      
        
           

        

        
          86

          
            

          

        

        
           

        

      

      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.

        CitiMortgage

       

      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

      
        
           

        

        
          87

          
            

          

        

        
           

        

      

      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
        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

      
        
           

        

        
          88

          
            

          

        

        
           

        

      

      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.

       

      5
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 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

      
        
           

        

        
          89

          
            

          

        

        
           

        

      

      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.

      (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

      
        
           

        

        
          90

          
            

          

        

        
           

        

      

      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.

      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

      
        
           

        

        
          91

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          92

          
            

          

        

        
           

        

      

      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 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 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 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.

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.

        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

      
        
           

        

        
          96

          
            

          

        

        
           

        

      

      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 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.

       

      8
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

      
        
           

        

        
          97

          
            

          

        

        
           

        

      

      notwithstanding
        anything to the contrary in this agreement, the Trustee will exercise those
        rights and powers vested 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

      
        
           

        

        
          98

          
            

          

        

        
           

        

      

      that
        of
        an independent contractor and not that of a joint venturer, partner or
        agent.

      (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

      ·      any
        erroneous information included in any federal, state or local income tax
        or

      
        
           

        

        
          99

          
            

          

        

        
           

        

      

      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 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 “F-1” 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
        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

      
        
           

        

        
          101

          
            

          

        

        
           

        

      

      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, 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-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

      
        
           

        

        
          103

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          104

          
            

          

        

        
           

        

      

      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 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

      
        
           

        

        
          105

          
            

          

        

        
           

        

      

      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
        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

      
        
           

        

        
          107

          
            

          

        

        
           

        

      

      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.

      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

      
        
           

        

        
          108

          
            

          

        

        
           

        

      

      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.

       

      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

      
        
           

        

        
          109

          
            

          

        

        
           

        

      

      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.

       

      11
        Depositories

       

      11.1
        Depositories

      CitiMortgage
        may transfer the certificate account, buydown account, if any, escrow account,
        custodial accounts for P&I or servicing account to a bank, savings and loan
        association or trust company organized under the laws of the United States
        or
        any State thereof (an “eligible depository”). Upon such transfer, such
        transferee bank, savings and loan association or trust company will be deemed
        to
        be a Depository for the transferred account or accounts.

      For
        a
        Depository of the certificate account, buydown account, escrow account,
        custodial accounts for P&I or servicing account to satisfy the “rating
        requirement”

      ·      its
        long-term debt obligations must be rated at least “A” by Fitch if Fitch is a
        rating agency, and

      ·      its
        short-term debt obligations are rated at least “A-1+” by S&P if S&P is a
        rating agency, “F-1” by Fitch if Fitch is a rating agency, and “P-1” by Moody’s
        if Moody’s is a rating agency.

      If
        a
        Depository ceases to satisfy the rating requirement, then within five business
        days after such cessation, CitiMortgage will

      (A)
        transfer or direct the Trustee to transfer the certificate account, buydown
        account, escrow account, custodial accounts for P&I or servicing account to
        an eligible depository that satisfies the rating requirements,

      (B)
        establish another account in the corporate trust department of the Trustee
        or if
        such Trustee satisfies the rating requirements, in any department of the
        Trustee
        (the “alternative certificate account,” “alternative buydown account,”
“alternative escrow account,” “alternative custodial accounts for P&I,” or
“alternative servicing account,” as the case may be) and transfer the funds from
        the buydown account to the alternative buydown account, direct CitiMortgage
        or a
        third-party servicer, as applicable, to remit in accordance with this agreement
        any funds deposited into the servicing account, escrow account or custodial
        accounts for P&I to the alternative servicing account, alternative
        escrow

      
        
           

        

        
          110

          
            

          

        

        
           

        

      

      account
        or alternative custodial account for P&I, respectively, and direct
        CitiMortgage to remit in accordance with this agreement any funds deposited
        into
        the certificate account to the alternative certificate account,

      (C)
        (i)
        cause the Depository to pledge securities in the manner provided by applicable
        law or (ii) pledge or cause to be pledged securities, which will be held
        by the
        Trustee or its agent free and clear of the lien of any third party, in a
        manner
        conferring on the Trustee a perfected first lien and otherwise reasonably
        satisfactory to the Trustee; such pledge in either case to secure the
        Depository’s performance of its obligations in respect of the certificate
        account, buydown account, escrow account, custodial accounts for P&I or
        servicing account to the extent, if any, that such obligation is not fully
        insured by the FDIC; provided, however, that prior to the day
        a Depository or CitiMortgage, as the case may be, pledges securities pursuant
        to
        this subsection (C), CitiMortgage, any Insurer and the Trustee have received
        the
        written assurance of each rating agency that the pledging of such securities
        and
        any arrangements or agreements relating thereto will not result in a reduction
        or withdrawal of the then-current rating of any class of certificates (for
        any
        insured class certificates, without reference to any certificate insurance
        policy),

      (D)
        establish an account or accounts or enter into an agreement so that the existing
        certificate account, buydown account, escrow account, custodial accounts
        for
        P&I or servicing account is supported by a letter of credit or some other
        form of credit support, which issuer of such letter of credit or other form
        of
        credit support has a long-term and short-term debt rating at least equal
        to the
        rating requirements; provided, however, that prior to the
        establishment of such an account or the entering into of such an agreement,
        CitiMortgage, any Insurer and the Trustee receive written assurance from
        each
        rating agency that the establishment of such an account or the entering into
        of
        such an agreement so that the existing certificate account, buydown account
        or
        servicing account is supported by a letter of credit or some other form of
        credit support will not result in a reduction or withdrawal of the then-current
        rating of any class of certificates (for an insured class certificates, without
        reference to a certificate insurance policy),

      (E)
        establish another account which constitutes an Eligible Account, or

      (F)
        make
        such other arrangements as to which CitiMortgage, any Insurer and the Trustee
        have received prior written assurance from each rating agency that such
        arrangement will not result in a reduction or withdrawal of the then-current
        rating of any class of certificates.

      If
        the
        rating on a class of certificates has been downgraded as a result of a rating
        downgrade of the Depository, for purposes of this paragraph, the then-current
        rating on such class of certificates will be the rating assigned to the class
        of
        certificates prior to any such downgrade (for any insured class certificates,
        without reference to any certificate insurance policy).

        any

        foregoing provisions of ERISA or the Internal Revenue Code (collectively,
        a
“Plan”) or a person investing the assets of a Plan.

      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.

        as
        CMALT (CitiMortgage Alternative Loan Trust), Series 2007-A6 REMIC Pass-Through
        Certificates, consisting of twenty-six senior classes, six subordinated classes
        and three classes of residual certificates.

       

      The
        class
        of securities represented by this certificate is a “regular interest” in a real
        estate mortgage investment conduit (“REMIC”) within the meaning of Section

      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.

        rights, limitations (including restrictions on transfer), duties and immunities
        of CMSI, the Trustee and the holders of the certificates, specifies how amounts

        of the classes of certificates to payments and to allocation of losses, and

                  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

      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

        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

      June
        1, 2007

       

      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

      

      June
        1, 2007

       

      (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

      (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.

        Mortgage
          Note Custodial Agreement

      

      June
        1, 2007

       

       

      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

      Ladies
        and Gentlemen:

      

      In
        connection with the purchase by us of $_____________________ initial
        principal
        balance of the CMALT (CitiMortgage Alternative Loan Trust), Series 2007-A6
        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.

      

      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.

      Ladies
        and Gentlemen:

      

      The
        purpose of this letter agreement (“Agreement”) is to
        confirm the terms and conditions of the rate Cap Transaction entered into
        on the
        Trade Date specified below (the “Transaction”) between
        The Bank of New York (“BNY”), a trust company duly
        organized and existing under the laws of the State of New York, and U.S Bank
        National Association, not in its individual capacity, but solely as trustee
        (in
        such capacity, the “Trustee”) under the Pooling and
        Servicing Agreement, dated as of June 1, 2007, among Citicorp Mortgage
        Securities, Inc., as depositor (the “Depositor”),
        CitiMortgage, Inc., as servicer (the “Servicer”) and
        master servicer (the “Master Servicer”), Citibank,
        N.A., as paying agent, certificate registrar and authenticating agent and
        the
        Trustee (the “Pooling and Servicing
        Agreement”).  CMALT (CitiMortgage Alternative Loan
        Trust), Series 2007-A6 (the “Issuing Entity”) is referred to herein as the
“Counterparty”.  This Agreement, which evidences a complete and
        binding agreement between you and us to enter into the Transaction on the
        terms
        set forth below, constitutes a “Confirmation” as
        referred to in the “ISDA Form Master Agreement” (as
        defined below), as well as a “Schedule” as referred to in the ISDA Form Master
        Agreement.

      

      1.           Form
        of Agreement.  This Agreement is subject to the 2000 ISDA
        Definitions (the

        (“ISDA”).  You and we have agreed to enter
        into this Agreement in lieu of negotiating a Schedule to the 1992 ISDA Master
        Agreement (Multicurrency—Cross Border) form (the
“ISDA Form Master
        Agreement”).  An ISDA Form Master Agreement, as modified
        by the Schedule terms in Paragraph 4 of this Confirmation (the
“Master Agreement”), shall be deemed to have been
        executed by you and us on the date we entered into the
        Transaction.  Except as otherwise specified, references herein to
        Sections shall be to Sections of the ISDA Form Master Agreement and the Master
        Agreement, and references to Paragraphs shall be to paragraphs of this
        Agreement. In the event of any inconsistency between the provisions of this
        Agreement and the Definitions or the ISDA Form Master Agreement, this Agreement
        shall prevail for purposes of the Transaction.  Capitalized terms not
        otherwise defined herein or in the Definitions or the Master Agreement shall
        have the meaning defined for such term in the Pooling and Servicing
        Agreement.

        Certificates.

       

      (B)           “Qualifying
        Ratings” means, with respect to the debt of any assignee or
        guarantor under Paragraph 4(9)(ii) below,

       

      (x)           a
        short-term unsecured and unsubordinated debt rating of “P-1” (not on watch for
        downgrade), and a long-term unsecured and unsubordinated debt of ”A1” (not on
        watch for downgrade) (or, if it has no short-term unsecured and unsubordinated
        debt rating, a long term rating of “Aa3” (not on watch for downgrade) by

      (x)           its
        short-term unsecured and unsubordinated debt rating is reduced to “P-1” (and is
        on watch for downgrade) or below, and its long-term unsecured and unsubordinated
        debt is reduced to ”A1” (and is on watch for downgrade) or below (or, if it has
        no short-term unsecured and unsubordinated debt rating, its long term rating
        is
        reduced to “Aa3” (and is on watch for downgrade) or below) by Moody’s,

        to
“P-2” or below by Moody’s and its long-term unsecured and unsubordinated debt is
        reduced to “A3” or below (or, if it has no short-term unsecured and
        unsubordinated debt rating, its long term rating is reduced to “A2” or below) by
        Moody’s, or

       

      (y)           its
        long-term unsecured and unsubordinated debt rating is withdrawn  or
        reduced below “BBB-” by S&P, or

        long-term unsecured and unsubordinated debt rating is withdrawn  or
        reduced below “BBB-” by Fitch.

       

      For
        purposes of (C) and (D) above, such events include those occurring in connection
        with a merger, consolidation or other similar transaction by BNY or any
        applicable credit support provider, but they shall be deemed not to occur
        if,
        within 30 days (or, in the case of a Ratings Event, 10 Business Days)
        thereafter, each of the applicable Rating Agencies has reconfirmed the ratings
        of the Certificates, as applicable, which were in effect immediately prior
        thereto.  For the avoidance of doubt, a downgrade of the rating on the
        Certificates could occur in the event that BNY does not post sufficient
        collateral.

       

      (ii)           Actions
        to be Taken Upon Occurrence of Event.  Subject, in each case
        set forth in (A) and (B) below, to satisfaction of the Rating Agency
        Condition:

       

      (A)           Collateralization
        Event.  If a Collateralization Event occurs with respect
        to BNY (or any applicable credit support provider), then BNY shall, at its
        own
        expense, within thirty (30) days of such Collateralization Ratings
        Event:

       

      (1)           post
        collateral under agreements and other instruments approved by the Counterparty,
        such approval not to be unreasonably withheld, which will be sufficient to
        restore the immediately prior ratings of the Certificates,

       

      (2)           assign
        the Transaction to a third party, the ratings of the debt of which (or of
        the
        guarantor of which) meet or exceed the Qualifying Ratings, on terms
        substantially similar to this Confirmation, which party is approved by the
        Counterparty, such approval not to be unreasonably withheld,

       

      (3)           obtain
        a guaranty of, or a contingent agreement of, another person, the ratings
        of the
        debt of which (or of the guarantor of which) meet or exceed the Qualifying
        Ratings, to honor BNY’s obligations under this Agreement, provided that
        such other person is approved by the Counterparty, such approval not to be
        unreasonably withheld, or

       

      (4)           establish
        any other arrangement approved by the Counterparty, such approval not to
        be
        unreasonably withheld, which will be sufficient to restore the immediately
        prior
        ratings of their Certificates.

       

      (B)           Ratings
        Event.  If a Ratings Event occurs with respect to BNY
        (or any applicable credit support provider), then BNY shall, at its own expense,
        within ten (10) Business Days of such Ratings Event:

       

      (1)           assign
        the Transaction to a third party, the ratings of the debt of which (or of
        the
        guarantor of which) meet or exceed the Qualifying Ratings, on terms
        substantially similar to this

      Confirmation,
        which party is approved by the Counterparty, such approval not to be
        unreasonably withheld,

       

      (2)           obtain
        a guaranty of, or a contingent agreement of, another person, the ratings
        of the
        debt of which (or of the guarantor of which) meet or exceed the Qualifying
        Ratings, to honor BNY’s obligations under this Agreement, provided that
        such other person is approved by the Counterparty, such approval not to be
        unreasonably withheld, or

       

      (3)           establish

        be
        unreasonably withheld, which will be sufficient to restore the immediately
        prior
        ratings of the Certificates.

                  satisfied

                  or
                  otherwise returns to the Counterparty upon demand of the Counterparty
                  any
                  portion of such payment, (a) the occurrence of an event described
                  in
