                                   Overcollateralization Amount

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

(1)   The interest rate with respect to any Distribution Date for these
      interests is a per annum variable rate equal to the Net WAC Rate.

      Each Lower-Tier REMIC Regular Interest is hereby designated as a regular
interest in the Lower-Tier REMIC. The Class LT-A-1a, Class LT-A-1b, Class
LT-A-2, Class LT-A-3, Class LT-A-4, Class LT-A-5, Class LT-A-6, Class LT-M-1,
Class LT-M-2, Class LT-M-3, Class LT-M-4, Class LT-M-5, Class LT-M-6, Class
LT-M-7, Class LT-M-8 and Class LT-M-9 Interests are hereby designated the LT
Accretion Directed Classes (the "LT Accretion Directed Classes").

      On each Distribution Date, 50% of the increase in the
Overcollateralization Amount shall be payable as a reduction of the Lower-Tier
REMIC Principal Amount of the LT Accretion Directed Classes (each such Class
will be reduced by an amount equal to 50% of any increase in the
Overcollateralization Amount that is attributable to a reduction in the
Certificate Balance of its Corresponding Class) and shall be accrued and added
to the Lower-Tier REMIC Principal Amount of the Class LT-Accrual Interest. On
each Distribution Date, the increase in the Lower-Tier REMIC Principal Amount of
the Class LT-Accrual Interest shall not exceed interest accruals for such
Distribution Date for the Class LT-Accrual Interest. In the event that: (i) 50%
of the increase in the Overcollateralization Amount exceeds (ii) interest
accruals on the Class LT-Accrual Interest for such Distribution Date, the excess
for such Distribution Date (accumulated with all such excesses for all prior
Distribution Dates) will be added to any increase in the Overcollateralization
Amount for purposes of determining the amount of interest accrual on the Class
LT-Accrual Interest payable as principal on the LT Accretion Directed Classes on
the next Distribution Date pursuant to the first sentence of this paragraph. All
payments of scheduled principal and prepayments of principal generated by the
Mortgage Loans and all Subsequent Recoveries allocable to principal shall be
allocated (i) 50% to the Class LT-Accrual Interest and (ii) 50% to the LT
Accretion Directed Classes (such principal payments and Subsequent Recoveries
shall be allocated among such LT Accretion Directed Classes in an amount equal
to 50% of the principal amounts and Subsequent Recoveries allocated to their
respective Corresponding Classes), until paid in full. Notwithstanding the
above, principal payments allocated to the Class CE Interest that result in the
reduction in the Overcollateralization Amount shall be allocated to the Class
LT-Accrual Interest (until paid in full). Realized Losses shall be applied so
that after all distributions have been made on each Distribution Date (i) the
Lower-Tier REMIC Principal Amount of each of the LT Accretion Directed Classes
is equal to 50% of the Certificate Balance of their Corresponding Class, and
(ii) the Class LT-Accrual Interest is equal to 50% of the aggregate Stated
Principal Balance of the Mortgage Loans plus 50% of the Overcollateralization
Amount. Any increase in the Certificate Balance of a Class of Certificates as a
result of a Subsequent Recovery shall increase the Lower-Tier REMIC Principal
Amount of the Corresponding Lower-Tier REMIC Regular Interest by 50% of such
increase, and the remaining 50% of such increase shall increase the Lower-Tier
REMIC Principal Amount of the Class LT-Accrual Interest.

                                Upper-Tier REMIC

      The Upper-Tier REMIC shall issue the interests designated in the table
below and the Class UT-R Interest, and each such interest, other than the Class
UT-R Interest, is hereby designated as a regular interest in the Upper-Tier
REMIC ("Upper-Tier REMIC Regular Interest"). The Class UT-R Interest is hereby
designated as the sole class of residual interests in the Upper-Tier REMIC and
shall be represented by the Class R Certificate.

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

(1)   For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the lesser of (i) the Certificate Rate
      (determined without regard to the Net WAC Rate) for the Corresponding
      Class of Certificates and (ii) the Net WAC Rate.

(2)   The Class CE Interest has an initial principal balance of $24,700,642.26
      but will not accrue interest on such balance but will accrue interest on a
      notional principal balance. As of any Distribution Date, the Class CE
      Interest shall have a notional principal balance equal to the aggregate of
      the Lower-Tier REMIC Principal Amounts of the Lower-Tier REMIC Regular
      Interests as of the first day of the related Interest Accrual Period. With
      respect to any Interest Accrual Period, the Class CE Interest shall bear
      interest at a rate equal to the excess, if any, of the Net WAC Rate over
      the product of (i) 2 and (ii) the weighted average of the Lower-Tier REMIC
      Interest Rates of the Lower-Tier REMIC Regular Interests, where the
      Lower-Tier REMIC Interest Rate on the Class LT-Accrual Interest is subject
      to a cap equal to zero and each LT Accretion Directed Class is subject to
      a cap equal to the Upper-Tier REMIC Interest Rate on its Corresponding
      Class of Upper-Tier REMIC Regular Interest. With respect to any
      Distribution Date, interest that so accrues on the notional principal
      balance of the Class CE Interest shall be deferred in an amount equal to
      any increase in the Overcollateralization Amount on such Distribution
      Date. Such deferred interest shall not itself bear interest.

      On each Distribution Date, interest distributable in respect of the
Lower-Tier REMIC Regular Interests for such Distribution Date shall be deemed to
be distributed on the interests in the Upper-Tier REMIC at the rates shown
above.

      On each Distribution Date, all Realized Losses, Subsequent Recoveries and
all payments of principal shall be allocated to the Upper-Tier REMIC Regular
Interests until the outstanding principal balance of each such interest equals
the outstanding Class A Subclass Principal Balance or Class M Subclass Principal
Balance of the Corresponding Class of Certificates as of such Distribution Date.

(b) CRMSI, on behalf of the Trustee, shall deposit in the Collection Account in
accordance with Section 3.06 all Scheduled Payments received by it, all other
deposits required to be made to the Collection Account and all investments made
with moneys on deposit in the Collection Account, including all income or gain
from such investments, if any. If the Certificate Account is an Investment
Account, then funds on deposit in the Certificate Account shall be held and
invested in accordance with the applicable provisions of Section 4.03.
Distributions from the Certificate Account shall be made in accordance with the
provisions of Articles XII and XIII to make payments in respect of the
Certificates and to pay the Servicing Fee in accordance with Section 3.13.
Amounts distributable as Cap Amounts to the related Certificates pursuant to
Section 13.01(b) shall first be deemed distributed in respect of the Class CE
Interest and then paid outside of the Upper-Tier REMIC to the related
Certificates.

      The Servicer shall maintain books with respect to the Upper-Tier REMIC and
the Lower-Tier REMIC on a calendar year taxable year and on the accrual method
of accounting.

      (c) None of the Servicer, the Certificate Administrator, the Paying Agent,
the Certificate Registrar or the Trustee shall create, or permit the creation
of, any "interests" in either REMIC within the meaning of Code Section
860D(a)(2) other than the interests represented by the Certificates.

      (d) Except as otherwise provided in the Code, CRMSI shall not grant, and
none of the Servicer, the Certificate Administrator, the Paying Agent, the
Certificate Registrar or the Trustee shall accept, property unless (i)
substantially all of the property held by either REMIC constitutes either
"qualified mortgages" or "permitted investments" as defined in Code Sections
860G(a)(3) and (5), respectively, and (ii) no property shall be granted to
either REMIC after the Startup Day, unless such grant would not subject the
REMIC to the 100% tax on contributions to a REMIC after the Startup Day imposed
by Code Section 860G(d).

      (e) None of the Servicer, the Certificate Administrator, the Paying Agent,
the Certificate Registrar or the Trustee shall accept on behalf of the Trust
Fund or the Upper-Tier REMIC or the Lower-Tier REMIC any fee or other
compensation for services and shall not accept on behalf of the Trust Fund any
income from assets other than those permitted to be held by a REMIC.

      (f) None of the Servicer, the Certificate Administrator, the Paying Agent
or the Trustee shall sell or permit the sale of all or any portion of the
Mortgage Loans, or of an Eligible Investment held in an Investment Account
(other than in accordance with Sections 2.02, 2.03, 2.04 and 4.03(d)) unless
such sale is pursuant to a "qualified liquidation" as defined in Code Section
860F(a)(4)(A) and is in accordance with Section 9.01.

      Section 12.05. Expenses and Liabilities of the Trust Fund.

      To the extent not otherwise payable pursuant to another provision of this
Agreement, the Depositor shall be liable for all expenses, liabilities and
obligations of the Trust Fund (other than the obligation to make distributions
in reduction of Principal Balance of the Certificates and the obligation to make
distributions of interest on the Certificates). 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 shall prevent the Depositor from contesting any such tax, if permitted
by law, pending the outcome of such proceedings. If the Paying Agent determines
that on any Distribution Date the amount in the Collection Account, after the
distribution of all amounts required to be distributed to the Holders of the
Certificates has been made, is insufficient to pay expenses or meet any
obligations of the Trust Fund that are not otherwise payable pursuant to another
provision of this Agreement, the Paying Agent shall give notice of any shortfall
to the Depositor setting forth the basis for such determination and, within ten
Business Days of such notice, the Depositor shall deliver to the Paying Agent
immediately available funds in the amount of such expenses.

      Section 12.06. Tax Matters Person.

      If in any taxable year there will be more than one holder of Class R
Certificate, a tax matters person may be designated with respect to the REMIC,
who will have the same duties with respect to the Upper-Tier REMIC and the
Lower-Tier REMIC as those of a "tax matters partner" under Subchapter C of
Chapter 63 of Subtitle F of the Code, and who will be, in order of priority, (i)
the Servicer or an affiliate of the Servicer, if the Servicer or such affiliate
is the holder of a residual certificate of the Upper-Tier REMIC or the
Lower-Tier REMIC at any time during the taxable year or at the time such
designation is made, (ii) if the Servicer is not a holder of a residual
certificate of the Upper-Tier REMIC or the Lower-Tier REMIC at the relevant
time, the Servicer as agent for the holder of the residual certificate of the
Upper-Tier REMIC or the Lower-Tier REMIC, if such designation is permitted to be
made under the Code, or (iii) such holder of a residual certificate of the
Upper-Tier REMIC or the Lower-Tier 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
ss. 1.860F-4(d) and temporary Treasury Regulations ss. 301.6231(a)(7)-1T.

                 SUBORDINATION; PRIORITIES; ALLOCATION OF LOSSES

      Section 13.01. Subordination; Priority of Distributions.

      (a) The rights of the holders of any Subclass of Class M Certificates to
receive distributions in respect thereof on any Distribution Date shall be
subordinated to the rights of the Class A Certificateholders and the holders of
each Class M Subclass having a lower numerical designation to receive
distributions to the extent, and only to the extent, described herein. The right
of the Servicer to receive its Servicing Fee and its Additional Servicing
Compensation shall not be subordinated to the rights of Certificateholders.

      (b) On each Distribution Date, the aggregate amount of Interest Proceeds
and Principal Proceeds will be applied in the following amounts, to the extent
the amount thereof is sufficient therefor, in the manner and in the order of
priority as follows:

      1. The sum of Interest Proceeds and Principal Proceeds (in each case,
excluding all permitted withdrawals from the Collection Account pursuant to
Section 3.06(d)) will be applied sequentially, as follows:

            a. concurrently, to the Subclasses of Class A Certificates, pro
      rata, their respective Class A Subclass Interest Amounts and any Class A
      Subclass Interest Shortfalls for such Distribution Date;

            b. sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4,
      Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in
      that order, their respective Class M Subclass Interest Amounts for such
      Distribution Date;

            c. to the Subclasses of Class A Certificates, the amounts provided
      in Section 12.01(d) or (e), as applicable;

            d. sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4,
      Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in
      that order, in each case until their respective Principal Balance is
      reduced to zero, an amount equal to their Class M Subclass Principal
      Distribution Amount;

            e. sequentially to the Class M-1, Class M-2, Class M-3, Class M-4,
      Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in
      that order, an amount equal to any Class M Subclass Interest Shortfall for
      such Class for such Distribution Date or previously allocated thereto, and
      then, sequentially, in that order, an amount equal to any Applied Loss
      Amount allocated to such Class pursuant to Section 13.02 on such
      Distribution Date plus any Class M Subclass Loss Amount for such Class;

            f. first, concurrently to the Class A Certificates, pro rata, any
      Net Civil Relief Amounts and Net Non-Supported Amounts for such
      Subclasses, and then, sequentially, to the Class M-1, Class M-2, Class
      M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9
      Certificates, in that order, any Net Civil Relief Amounts and Net
      Non-Supported Amounts for such Class;

            g. first, concurrently to the Class A Certificates, pro rata, any
      Net Class A WAC Cap Amounts for such Subclasses, and then, sequentially,
      to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6,
      Class M-7, Class M-8 and Class M-9 Certificates, in that order, any Net
      Class M WAC Cap Amounts for such Class;

            h. to the Holder of the Class CE Certificates, the Class CE
      Distributable Amount; and

            i. to the Holder of the Class R Certificate, any remaining amount.

      2. It is the intention of the parties hereto that the portion of the Trust
Fund, exclusive of the Lower-Tier REMIC and Upper-Tier REMIC, be treated as a
grantor trust for purposes of Subpart E, Part I of Subchapter J of the Code. In
furtherance of such intention, neither the Servicer nor the Trustee shall vary
the investment of the Certificateholders in the grantor trust. Solely for REMIC
purposes, any amounts distributed pursuant to Section 13.01(b)(1)(g) shall be
deemed distributed to the Class CE Certificates in respect of the Class CE
Interest from the Upper-Tier REMIC and then deemed paid to the classes of
Certificates as described in Section 13.01(b)(1)(g) from the grantor trust.

      Section 13.02. Allocation of Realized Losses; Recoveries.

      (a) For any Distribution Date prior to the Subordination Depletion Date,
any Applied Loss Amount will be allocated to the Subclasses of Class M
Certificates, first to the Class M Subclass with the highest numerical
designation and then in order of decreasing numerical designation, until their
respective Class M Subclass Principal Balance has been reduced to zero.

      This allocation of Applied Loss Amounts will be effected through the
reduction of the applicable Subclass Principal Balance. Any Applied Loss Amount
allocated in accordance with this Section 13.02 will be allocated on the
Distribution Date following the Collection Period in which such loss was
incurred and after giving effect to distributions made under Section 13.01 on
such Distribution Date.

      (b) Any Applied Loss Amount allocated to a Subclass of Class M
Certificates pursuant to Section 13.02(a) shall be allocated among the
Certificates of such Subclass pro rata based on their respective Principal
Balances.

      (c) In the event that Net Subsequent Recoveries are received by the
Servicer during a Prepayment Collection Period, immediately prior to the
Distribution Date to which such Prepayment Collection Period relates, an amount
equal to the amount of such Net Subsequent Recoveries shall be added to the
outstanding Class M Subclass Principal Balances of the Class M Subclasses, in
order of increasing numerical designation, but only if and to the extent that
the Class M Subclass had theretofore been allocated any Applied Loss Amount.

      (d) No Civil Relief Shortfall Amount, Net Civil Relief Amount, Unsupported
Prepayment Interest Shortfall or Net Non-Supported Amount will accrue interest.

      Section 13.03. [Reserved]

      Section 13.04. Distributions on the Class R Certificate.

      Upon a termination of the Trust in accordance with Section 9.01, the Class
R Certificate shall receive all amounts remaining in the Certificate Account
after all required distributions on the Class A, Class M and Class CE

Principal is paid on this certificate in accordance with the terms of the
Pooling Agreement. Accordingly, at any time the outstanding principal balance of
this certificate may be less than its initial principal amount.

This certificate represents an undivided beneficial ownership interest in the
Trust Fund created pursuant to the Pooling and Servicing Agreement dated as of
March 1, 2007 (the "Pooling Agreement") among Citicorp Residential Mortgage
Securities, Inc., as Depositor, CitiMortgage, Inc., as Servicer and Certificate
Administrator, Citibank, N.A., as Paying Agent, Certificate Registrar and
Authenticating Agent, and U.S. Bank National Association, as Trustee. Terms used
in this certificate that are defined in the Pooling Agreement have the meanings
assigned to them in the Pooling Agreement.

This certificate is one of a duly authorized issue of certificates designated as
Citicorp Residential Mortgage Securities, Inc. REMIC Pass-Through Certificates,
Series 2007-1, consisting of, for REMIC purposes, seven senior classes, ten
subordinated classes and one class of residual certificates.

The class of securities represented by this certificate constitutes an interest
in a "regular interest" in a real estate mortgage investment conduit ("REMIC")
within the meaning of Section 860G(a)(1) of the Internal Revenue Code of 1986,
as amended, and in certain other assets.

                   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 the Depositor, the Servicer, the Trustee, the Certificate Administrator, the
Paying Agent, the Certificate Registrar 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 CitiMortgage, Inc. (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. [In the event
this right is not exercised at such time, the certificate rate of the class
A-[*] Certificates will equal the certificate rate listed on the first page of
this Certificate plus 0.50% per annum, subject to and in accordance with the
terms of the Pooling Agreement.] [In the event this right is not exercised at
such time, the Class A-1b Margin on the class A-1b Certificates will increase to
double its original percentage, subject to and in accordance with the terms of
the Pooling Agreement.]

                                  Governing law

This certificate and the Pooling Agreement are governed by the laws of the State
of New York.

      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

documents so released will be held by the recipient in trust for the benefit of

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 Files 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 Files; 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.

   (b) To the extent provided under Section 8.05(b) of the Pooling Agreement,
CitiMortgage will indemnify Citibank and hold it harmless against any loss,
liability or expense incurred without 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 Files, including the costs and expenses of defending itself against
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder or under the Pooling Agreement. Such
indemnification will survive the payment of the certificates and termination of
the Trust Fund, as well as the resignation or removal of CitiMortgage as
Servicer (if such action which caused the need for the indemnification occurred
while CitiMortgage acted as Servicer), and for purposes of such indemnification
neither the negligence nor bad faith of the Trustee will be imputed to, or
adversely affect, the right of Citibank to indemnification.

7  Limitation of Custodian's Liabilities and Duties

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

representation or warranty with respect to, the validity, adequacy or perfection
of any lien upon or security interest in any Mortgage File.

   (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 File 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 Files), 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 CRMSI 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 CRMSI,
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 CRMSI, 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 CRMSI, 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

   o 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

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

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

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

   (l) Any entity into which Citibank may be merged or converted or with which
it may be consolidated, or any entity resulting from any merger, conversion or
consolidation to which Citibank will be a party, or any entity succeeding to the
business of Citibank, will be the successor of Citibank hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

8. Advice of Counsel

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

9. Effective Period, Termination and Amendment, and Interpretive and
Additional Provisions

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

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

10.   Binding Arbitration

   Any misunderstanding or dispute between Citibank and CRMSI 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, CRMSI or CitiMortgage may proceed to a court of
competent jurisdiction to obtain equitable relief at any time. An arbitrator may
not award punitive damages or other damages not measured by the prevailing
party's actual damages. To the maximum extent practicable, an arbitration
proceeding under this agreement will be concluded within 180 days of the filing
of the dispute with the AAA. This arbitration clause will survive any
termination or expiration of this agreement and if any term, covenant, condition
or provision of this arbitration clause is found to be unlawful, invalid or
unenforceable, the remaining parts of the arbitration clause will not be
affected thereby and will remain fully enforceable.

11.   Governing Law

   This agreement will be governed by, and construed in accordance with, the
laws of the State of New York.
