                                WITNESSETH THAT

      In consideration of the mutual agreements contained in this Agreement,
the parties to this Agreement agree as follows:

                             PRELIMINARY STATEMENT

      The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. The Trust Fund (excluding the
Pre-funding Account, the Capitalized Interest Account and the Carryover
Reserve Fund) for federal income tax purposes will consist of three REMICs
(the "Swap-IO REMIC," the " Strip REMIC" and the "Master REMIC"). Each
Certificate, other than the Class A-R Certificate, will represent ownership of
one or more regular interests in the Master REMIC for purposes of the REMIC
Provisions. The Class A-R Certificate will represent ownership of the sole
class of residual interest in each of the Swap-IO REMIC, the Strip REMIC and
the Master REMIC. The Master REMIC will hold as assets the several classes of
uncertificated Strip REMIC Interests (other than the STR-A-R Interest). Each
Strip REMIC Interest (other than the STR-A-R Interest) is hereby designated as
a regular interest in the Strip REMIC. The Strip REMIC will hold as assets the
several classes of uncertificated Swap-IO REMIC Interests (other than the
SWR-A-R Interest). Each Swap-IO REMIC Interest (other than the SWR-A-R
Interest) is hereby designated as a regular interest in the Swap-IO REMIC. The
Swap-IO REMIC will hold as assets all property of the Trust Fund (excluding
the Pre-funding Account, the Capitalized Interest Account and the Carryover
Reserve Fund). The latest possible maturity date of all REMIC regular
interests created in this Agreement shall be the Latest Possible Maturity
Date.

      The Swap Trust, the Swap Contract and the Swap Account will not
constitute any part of any REMIC.

(1)    This Strip REMIC Interest has a principal balance that is initially
equal to 100% of its corresponding Certificate Class issued by the Master
REMIC. Principal payments, both scheduled and prepaid, Realized Losses and
Subsequent Recoveries attributable to the SWAP-IO REMIC Interests held by the
Strip REMIC will be allocated to this class to maintain its size relative to
its corresponding Certificate Class.

(2)    On each Distribution Date, the pass through rate will equal the "Strip
REMIC Cap." The Strip REMIC Cap will equal the weighted average of the pass
through rates of the Swap-IO REMIC Interests (other than the Class SWR-P and
Class SWR-A-R Interests) treating each "B" Interest the cardinal number of
which (for example, SWR-1B, SWR-2B, SWR-3B, etc.) is not less than the ordinal
number of the Distribution Date (first Distribution Date, second Distribution
Date, third Distribution Date, etc., ) as capped at a rate equal to the
product of (i) 2 and (ii) LIBOR.

(3)    This Strip REMIC Interest pays no interest.

(4)    This Strip REMIC Interest has a principal balance that is initially
equal to 100% of the Overcollateralized Amount. Principal payments, both
scheduled and prepaid, Realized Losses and Subsequent Recoveries attributable
to the Swap-IO REMIC Interests held by the Strip REMIC will be allocated to
this class to maintain its size relative to the Overcollateralized Amount.

(5)    For each Distribution Date, the STR-C-Swap-IO Interest is entitled to
receive from each Swap REMIC "B" Interest the cardinal number of which (for
example, SWR-1B, SWR-2B, SWR-3B, etc.) is not less than the ordinal number of
the Distribution Date (first Distribution Date, second Distribution Date,
third Distribution Date, etc.) the interest accruing on such interest in
excess of a per annum rate equal to the product of (i) 2 and (ii) LIBOR.

(6)    The STR-P Interest is entitled to all amounts payable with respect to
the SWR-P Interest. It pays no interest.

(7)    The STR-A-R Interest is the sole class of residual interest in the Strip
REMIC. It has no principal balance and pays no principal or interest.

      On each Distribution Date, the Interest Funds and the Principal
Distribution Amount payable with respect to the Swap-IO Interests shall be
payable with respect to the Strip REMIC Interests in the following manner:

      (1) Interest. Interest is to be distributed with respect to each Strip
REMIC Interest at the rate, or according to the formulas, described above.

(2) Principal. Principal Distribution Amounts shall be allocated among the
Strip REMIC Interests as described above.

(3) Prepayment Penalties. All Prepayment Charges are allocated to the STR-P
Interest.

(1)    The Certificates will accrue interest at the related Pass-Through Rates
identified in this Agreement. For federal income tax purposes, including the
computation of the Class C Distributable Amount and entitlement to Net Rate
Carryover the pass-through rate in respect of each Class 1 Certificate, Class
2 Certificate and Class M Certificate will be subject to a cap equal to the
Strip REMIC Cap rather than the Net Rate Cap.

(2)    For federal income tax purposes, the Class C Certificates will be
treated as having a Class Certificate Balance equal to the Overcollateralized
Amount.

(3     For each Interest Accrual Period the Class C Certificates are entitled
to an amount (the "Class C Distributable Amount") equal to the sum of (a) the
interest payable on the STR-C-Swap-IO Interest, (b) the interest payable on
the STR-C-OC Interest and (c) a specified portion of the interest payable on
the Strip REMIC Regular Interests (other than the STR-$100, STR-C and STR-P
Interests) equal to the excess of the Pool Tax Cap over the weighted average
interest rate of the Strip REMIC Regular Interests (other than the STR-$100,
STR-C-OC and STR-P Interests) with each such Class subject to a cap and a
floor equal to the Pass-Through Rate of the Corresponding Master REMIC Class.
The Pass-Through Rate of the Class C Certificates shall be a rate sufficient
to entitle it to an amount equal to all interest accrued on the Mortgage Loans
less the interest accrued on the other interests issued by the Master REMIC.
The Class C Distributable Amount for any Distribution Date is payable from
current interest on the Mortgage Loans and any Overcollateralization Reduction
Amount for that Distribution Date.

(4)    For each Distribution Date the Class P Certificates are entitled to all
Prepayment Charges distributed with respect to the STR-P Interest.

(5)    The Class A-R Certificates represent the sole class of residual interest
in each REMIC created hereunder. The Class A-R Certificates are not entitled
to distributions of interest.

      The foregoing REMIC structure is intended to cause all of the cash from
the Mortgage Loans to flow through to the Master REMIC as cash flow on REMIC
regular interests, without


                                       8
<PAGE>


creating any shortfall--actual or potential (other than for credit losses)--
to any REMIC regular interest. It is not intended that the Class A-R
Certificates be entitled to any cash flows pursuant to this Agreement except
as provided in Section 4.02(b) hereunder.

Loan in accordance herewith.

            Countrywide further agrees (x) to cause The Bank of New York to
enter into the Swap Contract Administration Agreement as Swap Contract
Administrator and (y) to assign all of its right, title and interest in and to
the interest rate swap transaction evidenced by the Confirmation, and to cause
all of its obligations in respect of such transaction to be assumed by, the
Swap Contract Administrator, on the terms and conditions set forth in the Swap
Contract Assignment Agreement.

            (c) In connection with the transfer and assignment set forth in
clause (b) above, the Depositor has delivered or caused to be delivered to the
Trustee (or, in the case of the Delay Delivery Mortgage Loans that are Initial
Mortgage Loans, will deliver or cause to be delivered to the Trustee within
thirty (30) days following the Closing Date and in the case of the


                                      53
<PAGE>


Delay Delivery Mortgage Loans that are Supplemental Mortgage Loans, will
deliver or cause to be delivered to the Trustee within twenty (20) days
following the applicable Supplemental Transfer Date) for the benefit of the
Certificateholders the following documents or instruments with respect to each
Mortgage Loan so assigned:

               (i) (A) the original Mortgage Note endorsed by manual or
            facsimile signature in blank in the following form: "Pay to the
            order of ____________ without recourse," with all intervening
            endorsements showing a complete chain of endorsement from the
            originator to the Person endorsing the Mortgage Note (each such
            endorsement being sufficient to transfer all right, title and
            interest of the party so endorsing, as noteholder or assignee
            thereof, in and to that Mortgage Note); or

                  (B) with respect to any Lost Mortgage Note, a lost note
            affidavit from Countrywide stating that the original Mortgage Note

               (ii) except as provided below and for each Mortgage Loan that
             is not a MERS Mortgage Loan, the original recorded Mortgage or a
            copy of such Mortgage, with recording information, (or, in the
            case of a Mortgage for which the related Mortgaged Property is
            located in the Commonwealth of Puerto Rico, a true copy of the
            Mortgage certified as such by the applicable notary) and in the
            case of each MERS Mortgage Loan, the original Mortgage or a copy
            of such mortgage, with recording information, noting the presence
            of the MIN of the Mortgage Loans and either language indicating
            that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM
            Loan or if the Mortgage Loan was not a MOM Loan at origination,
            the original Mortgage and the assignment thereof to MERS, with
            evidence of recording indicated thereon, or a copy of the Mortgage
            certified by the public recording office in which such Mortgage
            has been recorded;

                (iii) in the case of each Mortgage Loan that is not a MERS
            Mortgage Loan, a duly executed assignment of the Mortgage or a
            copy of such assignment, with recording information, (which may be
            included in a blanket assignment or assignments), together with,
            except as provided below, all interim recorded assignments of such
            mortgage or a copy of such assignment, with recording information,
            (each such assignment, when duly and validly completed, to be in
            recordable form and sufficient to effect the assignment of and
            transfer to the assignee thereof, under the Mortgage to which the
            assignment relates); provided that, if the related Mortgage has
             not been returned from the applicable public recording office,
            such assignment of the Mortgage may exclude the information to be
            provided by the recording office; provided, further, that such
            assignment of Mortgage need not be delivered in the case of a
            Mortgage for which the related Mortgaged Property is located in
            the Commonwealth of Puerto Rico;

               (iv) the original or copies of each assumption, modification,
            written assurance or substitution agreement, if any;

<PAGE>


               (v)   except as provided below, the original or a copy of
            lender's title policy or a printout of the electronic equivalent
             and all riders thereto; and

               (vi) in the case of a Cooperative Loan, the originals of the
            following documents or instruments:

                    (A) The Coop Shares, together with a stock power in blank;

                     (B) The executed Security Agreement;

                    (C) The executed Proprietary Lease;

                    (D) The executed Recognition Agreement;

                    (E) The executed UCC-1 financing statement with evidence
                 of recording thereon which have been filed in all places
                 required to perfect the applicable Seller's interest in the
                 Coop Shares and the Proprietary Lease; and

                    (F) The executed UCC-3 financing statements or other
                 appropriate UCC financing statements required by state law,
                 evidencing a complete and unbroken line from the mortgagee to
                 the Trustee with evidence of recording thereon (or in a form
                  suitable for recordation).

      In addition, in connection with the assignment of any MERS Mortgage
Loan, each Seller agrees that it will cause, at the Trustee's expense, the
MERS(R) System to indicate that the Mortgage Loans sold by such Seller to the
Depositor have been assigned by that Seller to the Trustee in accordance with
this Agreement (and any Supplemental Transfer Agreement, as applicable) for
the benefit of the Certificateholders by including (or deleting, in the case
of Mortgage Loans which are repurchased in accordance with this Agreement) in
such computer files the information required by the MERS(R) System to identify
the series of the Certificates issued in connection with such Mortgage Loans.
Each Seller further agrees that it will not, and will not permit the Master
Servicer to, and the Master Servicer agrees that it will not, alter the
information referenced in this paragraph with respect to any Mortgage Loan
sold by such Seller to the Depositor during the term of this Agreement unless
and until such Mortgage Loan is repurchased in accordance with the terms of
this Agreement.

      In the event that in connection with any Mortgage Loan that is not a
MERS Mortgage Loan the Depositor cannot deliver (a) the original recorded
Mortgage or a copy of such mortgage, with recording information, or (b) all
interim recorded assignments or a copy of such assignments, with recording
information, or (c) the lender's title policy or a copy of lender's title
policy (together with all riders thereto) satisfying the requirements of
clause (ii), (iii) or (v) above, respectively, concurrently with the execution
and delivery of this Agreement because such document or documents have not
been returned from the applicable public recording office in the case of
clause (ii) or (iii) above, or because the title policy has not been delivered
to either the Master Servicer or the Depositor by the applicable title insurer
in the case of clause (v) above, the Depositor shall promptly deliver to the
Trustee, in the case of clause (ii) or (iii) above, such original Mortgage or
a copy of such mortgage, with recording information, or such interim


                                      55
<PAGE>


assignment or a copy of such assignments, with recording information, as the
case may be, with evidence of recording indicated thereon upon receipt thereof
from the public recording office, or a copy thereof, certified, if
appropriate, by the relevant recording office, but in no event shall any such
delivery of the original Mortgage and each such interim assignment or a copy
thereof, certified, if appropriate, by the relevant recording office, be made
later than one year following the Closing Date, or, in the case of clause (v)
above, no later than 120 days following the Closing Date; provided, however,
in the event the Depositor is unable to deliver by such date each Mortgage and
each such interim assignment by reason of the fact that any such documents
have not been returned by the appropriate recording office, or, in the case of
each such interim assignment, because the related Mortgage has not been
returned by the appropriate recording office, the Depositor shall deliver such
documents to the Trustee as promptly as possible upon receipt thereof and, in
any event, within 720 days following the Closing Date. The Depositor shall
forward or cause to be forwarded to the Trustee (a) from time to time
additional original documents evidencing an assumption or modification of a
Mortgage Loan and (b) any other documents required to be delivered by the
Depositor or the Master Servicer to the Trustee. In the event that the
original Mortgage is not delivered and in connection with the payment in full
of the related Mortgage Loan and the public recording office requires the
presentation of a "lost instruments affidavit and indemnity" or any equivalent
document, because only a copy of the Mortgage can be delivered with the
instrument of satisfaction or reconveyance, the Master Servicer shall execute
and deliver or cause to be executed and delivered such a document to the
public recording office. In the case where a public recording office retains
the original recorded Mortgage or in the case where a Mortgage is lost after
recordation in a public recording office, Countrywide shall deliver to the
Trustee a copy of such Mortgage certified by such public recording office to
be a true and complete copy of the original recorded Mortgage.

      As promptly as practicable subsequent to such transfer and assignment,
and in any event, within one hundred twenty (120) days after such transfer and
assignment, the Trustee shall (A) as the assignee thereof, affix the following
language to each assignment of Mortgage: "CWALT, Inc. Series 2006-OC11, The
Bank of New York as trustee", (B) cause such assignment to be in proper form
for recording in the appropriate public office for real property records and
(C) cause to be delivered for recording in the appropriate public office for
real property records the assignments of the Mortgages to the Trustee, except
that (i) with respect to any assignments of Mortgage as to which the Trustee
has not received the information required to prepare such assignment in
recordable form, the Trustee's obligation to do so and to deliver the same for
such recording shall be as soon as practicable after receipt of such
information and in any event within thirty (30) days after receipt thereof and
(ii) the Trustee need not cause to be recorded any assignment which relates to
a Mortgage Loan, the Mortgaged Property and Mortgage File relating to which
are located in any jurisdiction (including Puerto Rico) under the laws of
which the recordation of such assignment is not necessary to protect the
Trustee's and the Certificateholders' interest in the related Mortgage Loan as
evidenced by an opinion of counsel delivered by Countrywide to the Trustee
within 90 days of the Closing Date (which opinion may be in the form of a
"survey" opinion and is not required to be delivered by counsel admitted to
practice law in the jurisdiction as to which such legal opinion applies).

      In the case of Mortgage Loans that have been prepaid in full as of the
Closing Date, the Depositor, in lieu of delivering the above documents to the
Trustee, will deposit in the Certificate Account the portion of such payment
that is required to be deposited in the Certificate Account pursuant to
Section 3.05.


                                      56
<PAGE>


      Notwithstanding anything to the contrary in this Agreement, within
thirty (30) days after the Closing Date with respect to the Initial Mortgage
Loans, Countrywide (on its own behalf and on behalf of Park Granada, Park
Monaco and Park Sienna) shall either (i) deliver to the Depositor, or at the
Depositor's direction, to the Trustee or other designee of the Depositor the
Mortgage File as required pursuant to this Section 2.01 for each Delay
Delivery Mortgage Loan or (ii) either (A) substitute a Substitute Mortgage
Loan for the Delay Delivery Mortgage Loan or (B) repurchase the Delay Delivery
Mortgage Loan, which substitution or repurchase shall be accomplished in the
manner and subject to the conditions set forth in Section 2.03 (treating each
Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for purposes of such
Section 2.03); provided, however, that if Countrywide fails to deliver a
Mortgage File for any Delay Delivery Mortgage Loan within the thirty (30)-day
period provided in the prior sentence, Countrywide (on its own behalf and on
behalf of Park Granada, Park Monaco and Park Sienna) shall use its best
reasonable efforts to effect a substitution, rather than a repurchase of, such
Deleted Mortgage Loan and provided further that the cure period provided for
in Section 2.02 or in Section 2.03 shall not apply to the initial delivery of
the Mortgage File for such Delay Delivery Mortgage Loan, but rather
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) shall have five (5) Business Days to cure such failure to
deliver. At the end of such thirty (30)-day period the Trustee shall send a
Delay Delivery Certification for the Delay Delivery Mortgage Loans delivered
during such thirty (30)-day period in accordance with the provisions of
Section 2.02.

            (d) Subject to the execution and delivery of the related
Supplemental Transfer Agreement as provided in Section 2.01(e) hereof and the
terms and conditions of this Agreement, each Seller sells, transfers, assigns,
sets over and otherwise conveys to the Depositor, without recourse, on each
Supplemental Transfer Date, with respect to each Supplemental Mortgage Loan
sold by such Seller to the Depositor, all the right, title and interest of
that Seller in and to the Supplemental Mortgage Loans sold by it identified in
such Supplemental Transfer Agreement, including all interest and principal
received and receivable by such Seller on or with respect to the related
Supplemental Mortgage Loans on and after the related Supplemental Cut-off Date
(to the extent not applied in computing the Cut-off Date Principal Balance
thereof) or deposited into the Certificate Account by the related Seller,
other than principal and interest due on such Supplemental Mortgage Loans
prior to the related Supplemental Cut-off Date.

      Immediately upon the conveyance of the Supplemental Mortgage Loans
referred to in the preceding paragraph, the Depositor sells, transfers,
assigns, sets over and otherwise conveys to the Trustee for benefit of the
Certificateholders, without recourse, all right title and interest in all of
the Supplemental Mortgage Loans.

       Each Seller has entered into this Agreement in consideration for the
purchase of the Mortgage Loans sold by such Seller to the Depositor and has
agreed to take the actions specified herein. The Depositor, concurrently with
the execution and delivery of this Agreement, hereby sells, transfers, assigns
and otherwise conveys to the Trustee for the use and benefit of the
Certificateholders, without recourse, all right title and interest in the
portion of the Trust Fund not otherwise conveyed to the Trust Fund pursuant to
Sections 2.01(a) or (b).

            (e) Upon five (5) Business Days written notice to the Trustee, the
Depositor, the Master Servicer (if the Master Servicer is not a Seller) and
the Rating Agencies, on any other Business Day during the Funding Period
designated by Countrywide, Park Granada, Park Monaco and Park Sienna, if
applicable, the Depositor and the Trustee shall complete, execute


                                      57
<PAGE>


and deliver a Supplemental Transfer Agreement so long as no Rating Agency has
provided notice that the execution and delivery of such Supplemental Transfer
Agreement will result in a reduction or withdrawal of the any ratings assigned
to the Certificates. After the execution and delivery of such Supplemental
Transfer Agreement, on the Supplemental Transfer Date, the Trustee shall set
aside in the Pre-funding Account an amount equal to the Aggregate Supplemental
Purchase Amount.

      The transfer of Supplemental Mortgage Loans and the other property and
rights relating to them on a Supplemental Transfer Date is subject to the
satisfaction of each of the following conditions:

                  (i) each Supplemental Mortgage Loan conveyed on such
      Supplemental Transfer Date satisfies the representations and warranties
      applicable to it under this Agreement; provided, however, that with
      respect to a breach of a representation and warranty with respect to a
      Supplemental Mortgage Loan, the obligation under Section 2.03(c) of this
      Agreement of Countrywide, Park Granada, Park Monaco and Park Sienna, if
      applicable, to cure, repurchase or replace such Supplemental Mortgage
      Loan shall constitute the sole remedy against such Seller respecting
      such breach available to Certificateholders, the Depositor or the
      Trustee;

                  (ii) the Trustee, the Underwriter and the Rating Agencies
      are provided with an Opinion of Counsel or Opinions of Counsel with
      respect to the tax treatment of the Trust Fund, to be delivered as
      provided pursuant to Section 2.01(f);

                  (iii) the Rating Agencies and the Underwriter are provided
      with an Opinion of Counsel or Opinions of Counsel with respect to the
      validity of the conveyance of the Supplemental Mortgage Loans conveyed
      on such Supplemental Transfer Date, to be delivered as provided pursuant
      to Section 2.01(f);

                  (iv) the execution and delivery of such Supplemental
      Transfer Agreement or conveyance of the related Supplemental Mortgage
      Loans does not result in a reduction or withdrawal of any ratings
      assigned to the Certificates by the Rating Agencies;

                  (v) the Supplemental Mortgage Loans conveyed on such
      Supplemental Transfer Date were selected in a manner reasonably believed
      not to be adverse to the interests of the Certificateholders;

                  (vi) no Supplemental Mortgage Loan conveyed on such
      Supplemental Transfer date was 30 or more days delinquent;

                  (vii) following the conveyance of the Supplemental Mortgage
      Loans on such Supplemental Transfer Date to the Trust Fund, the
      characteristics of the Mortgage Loans will comply with the Pool
      Characteristics (including the permitted variances listed therein);
      provided, that for the purpose of making these calculations, the
      characteristics for any Initial Mortgage Loan made will be taken as of
      the Initial Cut-off Date and the characteristics for any Supplemental
      Mortgage Loan will be taken as of the related Supplemental Cut-off Date;


                                      58
<PAGE>


                  (ix) none of the Sellers or the Depositor shall be insolvent
      or shall be rendered insolvent as a result of such transfer; and

                  (x) the Depositor shall have delivered to the Trustee an
      Officer's Certificate confirming the satisfaction of each of these
      conditions precedent.

      The Trustee shall not be required to investigate or otherwise verify
compliance with these conditions, except for its own receipt of documents
specified above, and shall be entitled to rely on the required Officer's
Certificate.

            (f) Within seven Business Days after each Supplemental Transfer
Date, upon (1) delivery to the Trustee by the Depositor or Countrywide of the
Opinions of Counsel referred to in Sections 2.01(e)(ii) and (iii), (2)
delivery to the Trustee by Countrywide of a revised Mortgage Loan Schedule
reflecting the Supplemental Mortgage Loans conveyed on such Supplemental
Transfer Date to the Loan Group into which each Supplemental Mortgage Loan was
conveyed and (3) delivery to the Trustee by the Depositor of an Officer's
Certificate confirming the satisfaction of each of the conditions precedent
set forth in this Section 2.01(f), the Trustee shall pay to each Seller the
Aggregate Supplemental Transfer Amount for such Loan Group used to purchase
Supplemental Mortgage Loans for such Loan Group from such Seller from those
funds that were set aside in the Pre-funding Account pursuant to Section
2.01(e). The positive difference, if any, between the Aggregate Supplemental
Transfer Amount for such Loan Group and the Aggregate Supplemental Purchase
Amount for such Loan Group shall be reinvested by the Trustee in the
Pre-funding Account and shall remain designated as a portion of the Pre-funded
Amount allocated to such Loan Group.

            (g) The Trustee shall not be required to investigate or otherwise
verify compliance with the conditions set forth in the preceding paragraph,
except for its own receipt of documents specified above, and shall be entitled
to rely on the required Officer's Certificate.

      Within thirty days after the final Supplemental Transfer Date, the
Depositor shall deliver to the Trustee a letter of a nationally recognized
firm of independent public accountants stating whether or not the Supplemental
Mortgage Loans conveyed on such Supplemental Transfer Date conform to the
characteristics in Section 2.01(e)(vi), (vii) and (viii) for that Loan Group.

            (h) Neither the Depositor nor the Trust will acquire or hold any
Mortgage Loan that would violate the representations made by Countrywide set
forth in clause (50) of Schedule III-A hereto.

      SECTION 2.02.      Acceptance by Trustee of the Mortgage Loans.

      (a) The Trustee acknowledges receipt of the documents identified in the
Initial Certification in the form annexed hereto as Exhibit F-1 (an "Initial
Certification (Initial Mortgage Loans)") and declares that it holds and will
hold such documents and the other documents delivered to it constituting the
Mortgage Files, and that it holds or will hold such other assets as are
included in the Trust Fund, in trust for the exclusive use and benefit of all
present and future Certificateholders. The Trustee acknowledges that it will
maintain possession of the Mortgage Notes in the State of California, unless
otherwise permitted by the Rating Agencies.


                                      59
<PAGE>


      The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and Countrywide (on its own behalf and on
behalf of Park Granada, Park Monaco and Park Sienna) an Initial Certification
in the form annexed to this Agreement as Exhibit F-1. Based on its review and
examination, and only as to the documents identified in such Initial
Certification, the Trustee acknowledges that such documents appear regular on
their face and relate to the Initial Mortgage Loans. The Trustee shall be
under no duty or obligation to inspect, review or examine said documents,
instruments, certificates or other papers to determine that the same are
genuine, enforceable or appropriate for the represented purpose or that they
have actually been recorded in the real estate records or that they are other
than what they purport to be on their face.

      On or about the thirtieth (30th) day after the Closing Date, the Trustee
shall deliver to the Depositor, the Master Servicer and Countrywide (on its
own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Delay
Delivery Certification with respect to the Initial Mortgage Loans in the form
annexed hereto as Exhibit G-1 (a "Delay Delivery Certification (Initial
Mortgage Loans)"), with any applicable exceptions noted thereon.

      Not later than 90 days after the Closing Date, the Trustee shall deliver
to the Depositor, the Master Servicer and Countrywide (on its own behalf and
on behalf of Park Granada, Park Monaco and Park Sienna) a Final Certification
with respect to the Initial Mortgage Loans in the form annexed hereto as
Exhibit H-1 (a "Final Certification (Initial Mortgage Loans)"), with any
applicable exceptions noted thereon.

      If, in the course of such review, the Trustee finds any document
constituting a part of a Mortgage File that does not meet the requirements of
Section 2.01, the Trustee shall list such as an exception in the Final
Certification; provided, however that the Trustee shall not make any
determination as to whether (i) any endorsement is sufficient to transfer all
right, title and interest of the party so endorsing, as noteholder or assignee
thereof, in and to that Mortgage Note or (ii) any assignment is in recordable
form or is sufficient to effect the assignment of and transfer to the assignee
thereof under the mortgage to which the assignment relates. Countrywide (on
its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
shall promptly correct or cure such defect within 90 days from the date it was
so notified of such defect and, if Countrywide does not correct or cure such
defect within such period, Countrywide (on its own behalf and on behalf of
Park Granada, Park Monaco and Park Sienna) shall either (a) substitute for the
related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, or (b) purchase such Mortgage Loan from the Trustee within 90 days from
the date Countrywide (on its own behalf and on behalf of Park Granada, Park
Monaco and Park Sienna) was notified of such defect in writing at the Purchase
Price of such Mortgage Loan; provided, however, that in no event shall such
substitution or purchase occur more than 540 days from the Closing Date,
except that if the substitution or purchase of a Mortgage Loan pursuant to
this provision is required by reason of a delay in delivery of any documents
by the appropriate recording office, and there is a dispute between either the
Master Servicer or Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) and the Trustee over the location or
status of the recorded document, then such substitution or purchase shall
occur within 720 days from the Closing Date. The Trustee shall deliver written
notice to each Rating Agency within 270 days from the Closing Date indicating
each Mortgage Loan (a) that has not been returned by the appropriate recording
office or (b) as to which there is a dispute as to location or status of


                                      60
<PAGE>


such Mortgage Loan. Such notice shall be delivered every 90 days thereafter
until the related Mortgage Loan is returned to the Trustee. Any such
substitution pursuant to (a) above or purchase pursuant to (b) above shall not
be effected prior to the delivery to the Trustee of the Opinion of Counsel
required by Section 2.05, if any, and any substitution pursuant to (a) above
shall not be effected prior to the additional delivery to the Trustee of a
Request for Release substantially in the form of Exhibit N. No substitution is
permitted to be made in any calendar month after the Determination Date for
such month. The Purchase Price for any such Mortgage Loan shall be deposited
by Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco
and Park Sienna) in the Certificate Account on or prior to the Distribution
Account Deposit Date for the Distribution Date in the month following the
month of repurchase and, upon receipt of such deposit and certification with
respect thereto in the form of Exhibit N hereto, the Trustee shall release the
related Mortgage File to Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) and shall execute and deliver at
Countrywide's (on its own behalf and on behalf of Park Granada, Park Monaco
and Park Sienna) request such instruments of transfer or assignment prepared
by Countrywide, in each case without recourse, as shall be necessary to vest
in Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco
and Park Sienna), or its designee, the Trustee's interest in any Mortgage Loan
released pursuant hereto. If pursuant to the foregoing provisions Countrywide
(on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
repurchases an Initial Mortgage Loan that is a MERS Mortgage Loan, the Master
Servicer shall either (i) cause MERS to execute and deliver an assignment of
the Mortgage in recordable form to transfer the Mortgage from MERS to
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) or its designee and shall cause such Mortgage to be removed from
registration on the MERS(R) System in accordance with MERS' rules and
regulations or (ii) cause MERS to designate on the MERS(R) System Countrywide
(on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
or its designee as the beneficial holder of such Mortgage Loan.

            (b) Upon delivery of the Supplemental Mortgage Loans pursuant to a
Supplemental Transfer Agreement, the Trustee shall acknowledge receipt of the
documents identified in any Supplemental Certification in the form annexed
hereto as Exhibit F-2 (an "Initial Certification (Supplemental Mortgage
Loans)") and declare that it will hold such documents and the other documents
delivered to it constituting the Mortgage Files, and that it will hold such
other assets as are included in the Trust Fund, in trust for the exclusive use
and benefit of all present and future Certificateholders. The Trustee
acknowledges that it will maintain possession of the Mortgage Notes in the
State of California, unless otherwise permitted by the Rating Agencies.

            The Trustee agrees to execute and deliver on the Supplemental
Transfer Date to the Depositor, the Master Servicer and Countrywide (on its
own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a
Supplemental Certification in the form annexed hereto as Exhibit F-2. Based on
its review and examination, and only as to the documents identified in such
Supplemental Certification, the Trustee shall acknowledge that such documents
appear regular on their face and relate to such Supplemental Mortgage Loan.
The Trustee shall be under no duty or obligation to inspect, review or examine
said documents, instruments, certificates or other papers to determine that
the same are genuine, enforceable or


                                      61
<PAGE>


appropriate for the represented purpose or that they have actually been
recorded in the real estate records or that they are other than what they
purport to be on their face.

            On or about the twentieth (20th) day after the Supplemental
Transfer Date, the Trustee shall deliver to the Depositor, the Master Servicer
and Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco
and Park Sienna) a Delay Delivery Certification with respect to the
Supplemental Mortgage Loans in the form annexed hereto as Exhibit G-2 (a
"Delay Delivery Certification (Supplemental Mortgage Loans)"), with any
applicable exceptions noted thereon.

            Not later than 90 days after the final Supplemental Transfer Date,
the Trustee shall deliver to the Depositor, the Master Servicer and
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) a Final Certification with respect to the Supplemental Mortgage
Loans in the form annexed hereto as Exhibit H-2 (a "Final Certification
(Supplemental Mortgage Loans)"), with any applicable exceptions noted thereon.

            (c) If, in the course of such review of the Mortgage Files
relating to the Supplemental Mortgage Loans, the Trustee finds any document
constituting a part of a Mortgage File which does not meet the requirements of
Section 2.01, the Trustee shall list such as an exception in the Final
Certification; provided, however that the Trustee shall not make any
determination as to whether (i) any endorsement is sufficient to transfer all
right, title and interest of the party so endorsing, as noteholder or assignee
thereof, in and to that Mortgage Note or (ii) any assignment is in recordable
form or is sufficient to effect the assignment of and transfer to the assignee
thereof under the mortgage to which the assignment relates. Countrywide (on
its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
shall promptly correct or cure such defect within 90 days from the date it was
so notified of such defect and, if Countrywide does not correct or cure such
defect within such period, Countrywide (on its own behalf and on behalf of
Park Granada, Park Monaco and Park Sienna) shall either (a) substitute for the
related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, or (b) purchase such Mortgage Loan from the Trustee within 90 days from
the date Countrywide (on its own behalf and on behalf of Park Granada, Park
Monaco and Park Sienna) was notified of such defect in writing at the Purchase
Price of such Mortgage Loan; provided, however, that in no event shall such
substitution or purchase occur more than 540 days from the Closing Date,
except that if the substitution or purchase of a Mortgage Loan pursuant to
this provision is required by reason of a delay in delivery of any documents
by the appropriate recording office, and there is a dispute between either the
Master Servicer or Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) and the Trustee over the location or
status of the recorded document, then such substitution or purchase shall
occur within 720 days from the Closing Date. The Trustee shall deliver written
notice to each Rating Agency within 270 days from the Closing Date indicating
each Mortgage Loan (a) which has not been returned by the appropriate
recording office or (b) as to which there is a dispute as to location or
status of such Mortgage Loan. Such notice shall be delivered every 90 days
thereafter until the related Mortgage Loan is returned to the Trustee. Any
such substitution pursuant to (a) above or purchase pursuant to (b) above
shall not be effected prior to the delivery to the Trustee of the Opinion of
Counsel required by Section 2.05 hereof, if any, and any substitution pursuant
to (a) above shall not be effected prior to the additional delivery to the
Trustee of a Request for Release substantially in the form of Exhibit N. No
substitution is permitted to be made in any calendar

month after the Determination Date for such month. The Purchase Price for any
such Mortgage Loan shall be deposited by Countrywide (on its own behalf and on
behalf of Park Granada, Park Monaco and Park Sienna) in the Certificate
Account on or prior to the Distribution Account Deposit Date for the
Distribution Date in the month following the month of repurchase and, upon
receipt of such deposit and certification with respect thereto in the form of
Exhibit N hereto, the Trustee shall release the related Mortgage File to
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) and shall execute and deliver at Countrywide's (on its own behalf
and on behalf of Park Granada, Park Monaco and Park Sienna) request such
instruments of transfer or assignment prepared by Countrywide, in each case
without recourse, as shall be necessary to vest in Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park Sienna), or a
designee, the Trustee's interest in any Mortgage Loan released pursuant
hereto. If pursuant to the foregoing provisions Countrywide (on its own behalf
and on behalf of Park Granada, Park Monaco and Park Sienna) repurchases a
Supplemental Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer
shall either (i) cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to Countrywide
(on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
and shall cause such Mortgage to be removed from registration on the MERS(R)
System in accordance with MERS' rules and regulations or (ii) cause MERS to
designate on the MERS(R) System Countrywide (on its own behalf and on behalf
of Park Granada, Park Monaco and Park Sienna) or its designee as the
beneficial holder of such Mortgage Loan.

      (d) The Trustee shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth in
this Agreement. The Master Servicer shall promptly deliver to the Trustee,
upon the execution or receipt thereof, the originals of such other documents
or instruments constituting the Mortgage File as come into the possession of
the Master Servicer from time to time.

      (e) It is understood and agreed that the respective obligations of each
Seller to substitute for or to purchase any Mortgage Loan sold to the
Depositor by it which does not meet the requirements of Section 2.01 above
shall constitute the sole remedy respecting such defect available to the
Trustee, the Depositor and any Certificateholder against that Seller.

      SECTION 2.03.      Representations, Warranties and Covenants of the
                        Sellers and Master Servicer.

            (a) Countrywide hereby makes the representations and warranties
set forth in (i) Schedule II-A, Schedule II-B, Schedule II-C and Schedule II-D
hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, (ii) Schedule III-A
hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, or if so specified
therein, as of the Initial Cut-off Date with respect to all of the Initial
Mortgage Loans and as of the related Supplemental Cut-off Date with respect to
all of the Supplemental Mortgage Loans, and (iii) Schedule III-B hereto, and

Loans. Park Granada hereby makes the representations and warranties set forth
in (i) Schedule II-B hereto, and by this reference incorporated herein, to the
Depositor,


                                      63
<PAGE>


the Master Servicer and the Trustee, as of the Closing Date and (ii) Schedule
III-C hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, or if so specified
therein, as of the Initial Cut-off Date with respect to the Initial Mortgage
Loans that are Park Granada Mortgage Loans and as of the related Supplemental
Cut-off Date with respect to the Supplemental Mortgage Loans that are Park

warranties set forth in (i) Schedule II-C hereto, and by this reference
incorporated herein, to the Depositor, the Master Servicer and the Trustee, as
of the Closing Date and (ii) Schedule III-D hereto, and by this reference
incorporated herein, to the Depositor, the Master Servicer and the Trustee, as
of the Closing Date, or if so specified therein, as of the Initial Cut-off
Date with respect to the Initial Mortgage Loans that are Park Monaco Mortgage
Loans and as of the related Supplemental Cut-off Date with respect to the
Supplemental Mortgage Loans that are Park Monaco Mortgage Loans. Park Sienna
hereby makes the representations and warranties set forth in (i) Schedule II-D
hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date and (ii) Schedule
III-E hereto, and by this reference incorporated herein, to the Depositor, the

Sienna Mortgage Loans.

      (b) The Master Servicer hereby makes the representations and warranties
set forth in Schedule IV hereto, and by this reference incorporated herein, to
the Depositor and the Trustee, as of the Closing Date.

      (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty with respect to a Mortgage Loan made pursuant to
Section 2.03(a) or a breach of a representation or warranty with respect to a
Supplemental Mortgage Loan under Section 2.01(e)(i) that materially and
adversely affects the interests of the Certificateholders in that Mortgage
Loan, the party discovering such breach shall give prompt notice thereof to
the other parties and the NIM Insurer. Each Seller hereby covenants that
within 90 days of the earlier of its discovery or its receipt of written
notice from any party of a breach of any representation or warranty with
respect to a Mortgage Loan sold by it pursuant to Section 2.03(a) and with
respect to a breach of a representation and warranty with respect to a
Supplemental Mortgage Loan sold by it under Section 2.01(e)(i) that materially
and adversely affects the interests of the Certificateholders in that Mortgage
Loan, it shall cure such breach in all material respects, and if such breach
is not so cured, shall, (i) if such 90-day period expires prior to the second
anniversary of the Closing Date, remove such Mortgage Loan (a "Deleted
Mortgage Loan") from the Trust Fund and substitute in its place a Substitute
Mortgage Loan, in the manner and subject to the conditions set forth in this
Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from
the Trustee at the Purchase Price in the manner set forth below; provided,
however, that any such substitution pursuant to (i) above shall not be
effected prior to the delivery to the Trustee of the Opinion of Counsel
required by Section 2.05, if any, and any such substitution pursuant to (i)
above shall not be effected prior to the additional delivery to the Trustee of
a Request for Release substantially in the form of Exhibit N and the Mortgage
File for any such Substitute Mortgage Loan. The Seller repurchasing a Mortgage
Loan pursuant to this Section 2.03(c) shall promptly reimburse the Master
Servicer and the Trustee for any expenses reasonably incurred by the Master
Servicer or the Trustee in respect of enforcing the remedies


                                      64
<PAGE>


for such breach. With respect to the representations and warranties described
in this Section which are made to the best of a Seller's knowledge, if it is
discovered by either the Depositor, a Seller or the Trustee that the substance
of such representation and warranty is inaccurate and such inaccuracy
materially and adversely affects the value of the related Mortgage Loan or the
interests of the Certificateholders therein, notwithstanding that Seller's
lack of knowledge with respect to the substance of such representation or
warranty, such inaccuracy shall be deemed a breach of the applicable
representation or warranty. Any breach of a representation set forth in
clauses (45) through (64) of Schedule III-A with respect to a Mortgage Loan in
Loan Group 1 shall be deemed to materially and adversely affect the
Certificateholders.

      With respect to any Substitute Mortgage Loan or Loans sold to the
Depositor by a Seller, Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) shall deliver to the Trustee for the
benefit of the Certificateholders the Mortgage Note, the Mortgage, the related
assignment of the Mortgage, and such other documents and agreements as are
required by Section 2.01, with the Mortgage Note endorsed and the Mortgage
assigned as required by Section 2.01. No substitution is permitted to be made
in any calendar month after the Determination Date for such month. Scheduled
Payments due with respect to Substitute Mortgage Loans in the month of
substitution shall not be part of the Trust Fund and will be retained by the
related Seller on the next succeeding Distribution Date. For the month of
substitution, distributions to Certificateholders will include the monthly
payment due on any Deleted Mortgage Loan for such month and thereafter that
Seller shall be entitled to retain all amounts received in respect of such
Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan
Schedule for the benefit of the Certificateholders to reflect the removal of
such Deleted Mortgage Loan and the substitution of the Substitute Mortgage
Loan or Loans and the Master Servicer shall deliver the amended Mortgage Loan
Schedule to the Trustee. Upon such substitution, the Substitute Mortgage Loan
or Loans shall be subject to the terms of this Agreement in all respects, and
the related Seller shall be deemed to have made with respect to such
Substitute Mortgage Loan or Loans, as of the date of substitution, the
representations and warranties made pursuant to Section 2.03(a) with respect
to such Mortgage Loan. Upon any such substitution and the deposit to the
Certificate Account of the amount required to be deposited therein in
connection with such substitution as described in the following paragraph, the
Trustee shall release the Mortgage File held for the benefit of the
Certificateholders relating to such Deleted Mortgage Loan to the related
Seller and shall execute and deliver at such Seller's direction such
instruments of transfer or assignment prepared by Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park Sienna), in each
case without recourse, as shall be necessary to vest title in that Seller, or
its designee, the Trustee's interest in any Deleted Mortgage Loan substituted
for pursuant to this Section 2.03.

      For any month in which a Seller substitutes one or more Substitute
Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer
will determine the amount (if any) by which the aggregate principal balance of
all Substitute Mortgage Loans sold to the Depositor by that Seller as of the
date of substitution is less than the aggregate Stated Principal Balance of
all Deleted Mortgage Loans repurchased by that Seller (after application of
the scheduled principal portion of the monthly payments due in the month of
substitution). The amount of such shortage (the "Substitution Adjustment
Amount") plus an amount equal to the aggregate of any unreimbursed Advances
with respect to such Deleted Mortgage Loans shall be deposited in the


                                      65
<PAGE>


Certificate Account by Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) on or before the Distribution Account
Deposit Date for the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan became required to be purchased
or replaced hereunder.

      In the event that a Seller shall have repurchased a Mortgage Loan, the
Purchase Price therefor shall be deposited in the Certificate Account pursuant
to Section 3.05 on or before the Distribution Account Deposit Date for the
Distribution Date in the month following the month during which that Seller
became obligated hereunder to repurchase or replace such Mortgage Loan and
upon such deposit of the Purchase Price, the delivery of the Opinion of
Counsel required by Section 2.05 and receipt of a Request for Release in the
form of Exhibit N hereto, the Trustee shall release the related Mortgage File
held for the benefit of the Certificateholders to such Person, and the Trustee
shall execute and deliver at such Person's direction such instruments of
transfer or assignment prepared by such Person, in each case without recourse,
as shall be necessary to transfer title from the Trustee. It is understood and
agreed that the obligation under this Agreement of any Person to cure,
repurchase or replace any Mortgage Loan as to which a breach has occurred and
is continuing shall constitute the sole remedy against such Persons respecting
such breach available to Certificateholders, the Depositor or the Trustee on
their behalf.

      The representations and warranties made pursuant to this Section 2.03
shall survive delivery of the respective Mortgage Files to the Trustee for the
benefit of the Certificateholders.

      SECTION 2.04.      Representations and Warranties of the Depositor
                        as to the Mortgage Loans.

      The Depositor hereby represents and warrants to the Trustee with respect
to each Mortgage Loan as of the date of this Agreement or such other date set
forth in this Agreement that as of the Closing Date, and following the
transfer of the Mortgage Loans to it by each Seller, the Depositor had good
title to the Mortgage Loans and the Mortgage Notes were subject to no offsets,
defenses or counterclaims.

      The Depositor hereby assigns, transfers and conveys to the Trustee all
of its rights with respect to the Mortgage Loans including, without
limitation, the representations and warranties of each Seller made pursuant to
Section 2.03(a), together with all rights of the Depositor to require a Seller
to cure any breach thereof or to repurchase or substitute for any affected
Mortgage Loan in accordance with this Agreement.

      It is understood and agreed that the representations and warranties set
forth in this Section 2.04 shall survive delivery of the Mortgage Files to the
Trustee. Upon discovery by the Depositor or the Trustee of a breach of any of
the foregoing representations and warranties set forth in this Section 2.04
(referred to herein as a "breach"), which breach materially and adversely
affects the interest of the Certificateholders, the party discovering such
breach shall give prompt written notice to the others and to each Rating
Agency and the NIM Insurer.

      SECTION 2.05.      Delivery of Opinion of Counsel in Connection with
                        Substitutions.


                                      66
<PAGE>


      (a) Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 or Section 2.03 shall be made more than
90 days after the Closing Date unless Countrywide delivers to the Trustee an
Opinion of Counsel, which Opinion of Counsel shall not be at the expense of
either the Trustee or the Trust Fund, addressed to the Trustee, to the effect
that such substitution will not (i) result in the imposition of the tax on
"prohibited transactions" on the Trust Fund or contributions after the Startup
Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively,
or (ii) cause any REMIC created under this Agreement to fail to qualify as a
REMIC at any time that any Certificates are outstanding.

      (b) Upon discovery by the Depositor, a Seller, the Master Servicer, or
the Trustee that any Mortgage Loan does not constitute a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code, the party discovering
such fact shall promptly (and in any event within five (5) Business Days of
discovery) give written notice thereof to the other parties and the NIM
Insurer. In connection therewith, the Trustee shall require Countrywide (on
its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna) at
its option, to either (i) substitute, if the conditions in Section 2.03(c)
with respect to substitutions are satisfied, a Substitute Mortgage Loan for
the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan
within 90 days of such discovery in the same manner as it would a Mortgage
Loan for a breach of representation or warranty made pursuant to Section 2.03.
The Trustee shall reconvey to Countrywide the Mortgage Loan to be released
pursuant to this Section in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty contained in Section 2.03.

      SECTION 2.06.      Execution and Delivery of Certificates.

      The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, has executed and
delivered to or upon the order of the Depositor, the Certificates in
authorized denominations evidencing directly or indirectly the entire
ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and
exercise the rights referred to above for the benefit of all present and
future Holders of the Certificates and to perform the duties set forth in this
Agreement, to the end that the interests of the Holders of the Certificates
may be adequately and effectively protected.

      SECTION 2.07.      REMIC Matters.

      The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests
created hereby. The "Startup Day" for purposes of the REMIC Provisions shall
be the Closing Date. The "tax matters person" with respect to each REMIC
hereunder shall be the Trustee and the Trustee shall hold the Tax Matters
Person Certificate. Each REMIC's fiscal year shall be the calendar year.

      SECTION 2.08.      Covenants of the Master Servicer.

      The Master Servicer hereby covenants to the Depositor and the Trustee as
follows:

      (a) the Master Servicer shall comply in the performance of its
obligations under this Agreement with all reasonable rules and requirements of
the insurer under each Required Insurance Policy; and


                                      67
<PAGE>


      (b) no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, any
affiliate of the Depositor or the Trustee and prepared by the Master Servicer
pursuant to this Agreement will contain any untrue statement of a material
fact or omit to state a material fact necessary to make such information,
certificate, statement or report not misleading.

                                  ARTICLE III
                         ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

      SECTION 3.01.      Master Servicer to Service Mortgage Loans.

      For and on behalf of the Certificateholders, the Master Servicer shall
service and administer the Mortgage Loans in accordance with the terms of this
Agreement and customary and usual standards of practice of prudent mortgage
loan servicers. In connection with such servicing and administration, the
Master Servicer shall have full power and authority, acting alone and/or
through Subservicers as provided in Section 3.02, subject to the terms of this
Agreement (i) to execute and deliver, on behalf of the Certificateholders and
the Trustee, customary consents or waivers and other instruments and
documents, (ii) to consent to transfers of any Mortgaged Property and
assumptions of the Mortgage Notes and related Mortgages (but only in the
manner provided in this Agreement), (iii) to collect any Insurance Proceeds
and other Liquidation Proceeds (which for the purpose of this Section 3.01
includes any Subsequent Recoveries), and (iv) to effectuate foreclosure or
other conversion of the ownership of the Mortgaged Property securing any
Mortgage Loan; provided that the Master Servicer shall not take any action
that is inconsistent with or prejudices the interests of the Trust Fund or the
Certificateholders in any Mortgage Loan or the rights and interests of the
Depositor, the Trustee and the Certificateholders under this Agreement. The
Master Servicer shall represent and protect the interests of the Trust Fund in
the same manner as it protects its own interests in mortgage loans in its own
portfolio in any claim, proceeding or litigation regarding a Mortgage Loan,
and shall not make or permit any modification, waiver or amendment of any
Mortgage Loan which would cause any REMIC created under this Agreement to fail
to qualify as a REMIC or result in the imposition of any tax under section
860F(a) or section 860G(d) of the Code. Without limiting the generality of the
foregoing, the Master Servicer, in its own name or in the name of the
Depositor and the Trustee, is hereby authorized and empowered by the Depositor
and the Trustee, when the Master Servicer believes it appropriate in its
reasonable judgment, to execute and deliver, on behalf of the Trustee, the
Depositor, the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge and
all other comparable instruments, with respect to the Mortgage Loans, and with
respect to the Mortgaged Properties held for the benefit of the
Certificateholders. The Master Servicer shall prepare and deliver to the
Depositor and/or the Trustee such documents requiring execution and delivery
by either or both of them as are necessary or appropriate to enable the Master
Servicer to service and administer the Mortgage Loans to the extent that the
Master Servicer is not permitted to execute and deliver such documents
pursuant to the preceding sentence. Upon receipt of such documents, the
Depositor and/or the Trustee shall execute such documents and deliver them to
the Master Servicer. The Master Servicer further is authorized and empowered
by the Trustee, on behalf of the Certificateholders and the Trustee, in its
own name or in the name of the Subservicer, when the Master Servicer or the
Subservicer, as the case may be, believes it appropriate in its best judgment
to register any Mortgage Loan on the MERS(R) System, or cause the removal from
the registration of any Mortgage Loan on the MERS(R) System, to execute and
deliver, on behalf of the Trustee and the Certificateholders or any of them,
any and all instruments of assignment and other comparable instruments with
respect to such assignment or re-recording of a Mortgage in the name of MERS,
solely as nominee for the Trustee and its successors and assigns.


                                      69
<PAGE>


      In accordance with the standards of the preceding paragraph, the Master
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further
as provided in Section 3.08. The costs incurred by the Master Servicer, if
any, in effecting the timely payments of taxes and assessments on the
Mortgaged Properties and related insurance premiums shall not, for the purpose
of calculating monthly distributions to the Certificateholders, be added to
the Stated Principal Balances of the related Mortgage Loans, notwithstanding
that the terms of such Mortgage Loans so permit.

      SECTION 3.02.      Subservicing; Enforcement of the Obligations of
                        Subservicers.

       (a) The Master Servicer may arrange for the subservicing of any Mortgage
Loan by a Subservicer pursuant to a subservicing agreement; provided, however,
that such subservicing arrangement and the terms of the related subservicing
agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated under this Agreement;
provided, however, that the NIM Insurer shall have consented to such
subservicing agreements (which consent shall not be unreasonably withheld).
Unless the context otherwise requires, references in this Agreement to actions
taken or to be taken by the Master Servicer in servicing the Mortgage Loans
include actions taken or to be taken by a Subservicer on behalf of the Master
Servicer. Notwithstanding the provisions of any subservicing agreement, any of
the provisions of this Agreement relating to agreements or arrangements
between the Master Servicer and a Subservicer or reference to actions taken
through a Subservicer or otherwise, the Master Servicer shall remain obligated
and liable to the Depositor, the Trustee and the Certificateholders for the
servicing and administration of the Mortgage Loans in accordance with the
provisions of this Agreement without diminution of such obligation or
liability by virtue of such subservicing agreements or arrangements or by
virtue of indemnification from the Subservicer and to the same extent and
under the same terms and conditions as if the Master Servicer alone were
servicing and administering the Mortgage Loans. All actions of each
Subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

      (b) For purposes of this Agreement, the Master Servicer shall be deemed
to have received any collections, recoveries or payments with respect to the
Mortgage Loans that are received by a Subservicer regardless of whether such
payments are remitted by the Subservicer to the Master Servicer.

      SECTION 3.03.      Rights of the Depositor, the NIM Insurer and the
                        Trustee in Respect of the Master Servicer.

      The Depositor may, but is not obligated to, enforce the obligations of
the Master Servicer under this Agreement and may, but is not obligated to,
perform, or cause a designee to perform, any defaulted obligation of the
Master Servicer under this Agreement and in connection with any such defaulted
obligation to exercise the related rights of the Master Servicer under this
Agreement; provided that the Master Servicer shall not be relieved of any of
its obligations under this Agreement by virtue of such performance by the
Depositor or its designee. None of the Trustee, the NIM Insurer or the
Depositor shall have any responsibility or liability for any action


                                      70
<PAGE>


or failure to act by the Master Servicer nor shall the Trustee or the
Depositor be obligated to supervise the performance of the Master Servicer
under this Agreement or otherwise.

      SECTION 3.04.      Trustee to Act as Master Servicer.

      In the event that the Master Servicer shall for any reason no longer be
the Master Servicer under this Agreement (including by reason of an Event of
Default or termination by the Depositor), the Trustee or its successor shall
then assume all of the rights and obligations of the Master Servicer under
this Agreement arising thereafter (except that the Trustee shall not be (i)
liable for losses of the Master Servicer pursuant to Section 3.09 or any acts
or omissions of the predecessor Master Servicer under this Agreement), (ii)
obligated to make Advances if it is prohibited from doing so by applicable
law, (iii) obligated to effectuate repurchases or substitutions of Mortgage
Loans under this Agreement including, but not limited to, repurchases or
substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03, (iv)
responsible for expenses of the Master Servicer pursuant to Section 2.03 or
(v) deemed to have made any representations and warranties of the Master
Servicer under this Agreement). Any such assumption shall be subject to
Section 7.02. If the Master Servicer shall for any reason no longer be the
Master Servicer (including by reason of any Event of Default or termination by
the Depositor), the Trustee or its successor shall succeed to any rights and
obligations of the Master Servicer under each subservicing agreement.

      The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents
and records relating to each subservicing agreement or substitute subservicing
agreement and the Mortgage Loans then being serviced thereunder and an
accounting of amounts collected or held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of the substitute
subservicing agreement to the assuming party.

      SECTION 3.05.      Collection of Mortgage Loan Payments;
                        Certificate Account; Distribution Account; Carryover
                        Reserve Fund; Principal Reserve Fund; the Pre-funding
                        Account; the Capitalized Interest Account.

      (a) The Master Servicer shall make reasonable efforts in accordance with
the customary and usual standards of practice of prudent mortgage servicers to
collect all payments called for under the terms and provisions of the Mortgage
Loans to the extent such procedures shall be consistent with this Agreement
and the terms and provisions of any related Required Insurance Policy.
Consistent with the foregoing, the Master Servicer may in its discretion (i)
waive any late payment charge or, subject to Section 3.20, any Prepayment
Charge or penalty interest in connection with the prepayment of a Mortgage
Loan and (ii) extend the due dates for payments due on a Mortgage Note for a
period not greater than 180 days; provided, however, that the Master Servicer
cannot extend the maturity of any such Mortgage Loan past the date on which
the final payment is due on the latest maturing Mortgage Loan as of the
Cut-off Date. In the event of any such arrangement, the Master Servicer shall
make Advances on the related Mortgage Loan in accordance with the provisions
of Section 4.01 during the scheduled period in accordance with the
amortization schedule of such Mortgage Loan without modification thereof by
reason of such arrangements. In addition, the NIM Insurer's prior written
consent shall be required for any waiver of Prepayment Charges or for the
extension of the due dates for payments due on a Mortgage Note, if the
aggregate number of outstanding Mortgage Loans that


                                      71
<PAGE>


have been granted such waivers or extensions exceeds 5% of the aggregate
number of Mortgage Loans. The Master Servicer shall not be required to
institute or join in litigation with respect to collection of any payment
(whether under a Mortgage, Mortgage Note or otherwise or against any public or
governmental authority with respect to a taking or condemnation) if it
reasonably believes that enforcing the provision of the Mortgage or other
instrument pursuant to which such payment is required is prohibited by
applicable law.

      (b) The Master Servicer shall establish and maintain a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited
no later than two Business Days after receipt (or, if the current long-term
credit rating of Countrywide is reduced below "A-" by S&P or "A3" by Moody's,
the Master Servicer shall deposit or cause to be deposited on a daily basis
within one Business Day of receipt), except as otherwise specifically provided
in this Agreement, the following payments and collections remitted by
Subservicers or received by it in respect of Mortgage Loans subsequent to the
Cut-off Date (other than in respect of principal and interest due on the
Mortgage Loans on or before the Cut-off Date) and the following amounts
required to be deposited under this Agreement:

             (i) all payments on account of principal on the Mortgage Loans,
      including Principal Prepayments;

            (ii) all payments on account of interest on the Mortgage Loans,
      net of the related Master Servicing Fee, Prepayment Interest Excess and
      any lender paid mortgage insurance premiums;

            (iii) all Insurance Proceeds, Subsequent Recoveries and
      Liquidation Proceeds, other than proceeds to be applied to the
      restoration or repair of a Mortgaged Property or released to the
      Mortgagor in accordance with the Master Servicer's normal servicing
      procedures;

            (iv) any amount required to be deposited by the Master Servicer or
      the Depositor in connection with any losses on Permitted Investments for
      which it is responsible;

            (v) any amounts required to be deposited by the Master Servicer
      pursuant to Section 3.09(c) and in respect of net monthly rental income
      from REO Property pursuant to Section 3.11;

            (vi) all Substitution Adjustment Amounts;

            (vii) all Advances made by the Master Servicer pursuant to Section
      4.01;

            (viii) all Prepayment Charges collected; and

            (ix) any other amounts required to be deposited under this
      Agreement.

      In addition, with respect to any Mortgage Loan that is subject to a
buydown agreement, on each Due Date for such Mortgage Loan, in addition to the

equal to the amount of interest that has accrued on such Mortgage Loan from
the preceding Due Date at the Mortgage Rate net of the related Master
Servicing Fee.

      The foregoing requirements for remittance by the Master Servicer shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of late payment charges or
assumption fees, if collected, need not be remitted by the Master Servicer. In
the event that the Master Servicer shall remit any amount not required to be
remitted, it may at any time withdraw or direct the institution maintaining
the Certificate Account to withdraw such amount from the Certificate Account,
any provision in this Agreement to the contrary notwithstanding. Such
withdrawal or direction may be accomplished by delivering written notice
thereof to the Trustee or such other institution maintaining the Certificate
Account which describes the amounts deposited in error in the Certificate
Account. The Master Servicer shall maintain adequate records with respect to
all withdrawals made pursuant to this Section. All funds deposited in the
Certificate Account shall be held in trust for the Certificateholders until
withdrawn in accordance with Section 3.08.

      (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On

applicable Treasury regulations and shall not be part of any REMIC created
under this Agreement. Amounts on deposit in the Principal Reserve Fund shall
not be invested.

      (d) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account. The Trustee shall, promptly upon
receipt, deposit in the Distribution Account and retain in the Distribution
Account the following:

            (i) the aggregate amount remitted by the Master Servicer to the
      Trustee pursuant to Section 3.08(a)(ix);

            (ii) any amount deposited by the Master Servicer or the Depositor
      pursuant to Section 3.05(e) in connection with any losses on Permitted
      Investments for which it is responsible; and

            (iii) any other amounts deposited hereunder which are required to
      be deposited in the Distribution Account.

      In the event that the Master Servicer shall remit any amount not
required to be remitted, it may at any time direct the Trustee to withdraw
such amount from the Distribution Account, any provision in this Agreement to
the contrary notwithstanding. Such direction may be accomplished by delivering
an Officer's Certificate to the Trustee which describes the amounts deposited
in error in the Distribution Account. All funds deposited in the Distribution
Account shall be held by the Trustee in trust for the Certificateholders until
disbursed in accordance with this Agreement or withdrawn in accordance with
Section 3.08. In no event shall the Trustee incur liability for withdrawals
from the Distribution Account at the direction of the Master Servicer.

      (e) Each institution at which the Certificate Account, the Distribution
Account, the Pre-funding Account or the Capitalized Interest Account is
maintained shall invest the funds therein as directed in writing by the Master
Servicer in Permitted Investments, which shall mature not later than (i) in
the case of the Certificate Account, the Pre-funding Account and the
Capitalized Interest Account, the second Business Day next preceding the
related Distribution Account Deposit Date (except that if such Permitted
Investment is an obligation of the institution that maintains such account,
then such Permitted Investment shall mature not later than the Business Day
next preceding such Distribution Account Deposit Date) and (ii) in the case of
the Distribution Account, the Business Day next preceding the Distribution
Date (except that if such Permitted Investment is an obligation of the
institution that maintains such fund or account, then such Permitted
Investment shall mature not later than such Distribution Date) and, in each
case, shall not be sold or disposed of prior to its maturity. All such
Permitted Investments shall be made in the name of the Trustee, for the
benefit of the Certificateholders. All income and gain net of any losses
realized from any such investment of funds on deposit in the Certificate
Account, or the Distribution Account shall be for the benefit of the Master
Servicer as servicing compensation and shall be remitted to it monthly as
provided in this Agreement. The amount of any realized losses in the
Certificate Account or the Distribution Account incurred in any such account
in respect of any such investments shall promptly be deposited by the Master
Servicer in the Certificate Account or paid to the Trustee for deposit into
the Distribution Account, as applicable. The amount of any losses in the
Pre-funding Account or the Capitalized Interest Account incurred in respect of
any such investments shall promptly be deposited by the Depositor in the
Pre-funding Account or the Capitalized Interest Account, as applicable. All
income or gain (net of any losses) realized from any such investment of funds
on deposit in the Capitalized Interest Account shall be credited to the
Capitalized Interest Account. The Trustee in its fiduciary capacity shall not
be liable for the amount of any loss incurred in respect of any investment or
lack of investment of funds held in the Certificate Account, the Distribution
Account, the Pre-funding Account or the Capitalized Interest Account and made
in accordance with this Section 3.05.

      (f) The Master Servicer shall give notice to the Trustee, each Seller,
each Rating Agency and the Depositor of any proposed change of the location of
the Certificate Account prior to any change thereof. The Trustee shall give
notice to the Master Servicer, each Seller, each Rating Agency and the
Depositor of any proposed change of the location of the Distribution Account,
the Pre-funding Account, the Capitalized Interest Account or the Carryover
Reserve Fund prior to any change thereof.

      (g) On the Closing Date, the Trustee shall establish and maintain in its
name, in trust for the benefit of the Holders of the Offered Certificates, the
Carryover Reserve Fund and shall deposit $1,000 therein upon receipt from or
on behalf of the Depositor of such amount. The Carryover Reserve Fund shall be
an Eligible Account, and funds on deposit therein shall be held separate and
apart from, and shall not be commingled with, any other moneys, including
without limitation, other moneys held by the Trustee pursuant to this
Agreement.

      Funds in the Carryover Reserve Fund may be invested in Permitted
Investments at the direction of the Majority of the Holders of the Class C
Certificates, which Permitted Investments shall mature not later than the
Business Day immediately preceding the first Distribution Date that follows
the date of such investment (except that if such Permitted Investment is an
obligation of the institution that maintains the Carryover Reserve Fund, then
such Permitted


                                      74
<PAGE>


Investment shall mature not later than such Distribution Date) and shall not
be sold or disposed of prior to maturity. All such Permitted Investments shall
be made in the name of the Trustee, for the benefit of the Holders of the
Class C Certificates. In the absence of such written direction, all funds in
the Carryover Reserve Fund shall be invested by the Trustee in The Bank of New
York cash reserves. Any net investment earnings on such amounts shall be
retained therein until withdrawn as provided in Section 3.08. Any losses
incurred in the Carryover Reserve Fund in respect of any such investments
shall be charged against amounts on deposit in the Carryover Reserve Fund (or
such investments) immediately as realized. The Trustee shall not be liable for
the amount of any loss incurred in respect of any investment or lack of
investment of funds held in the Carryover Reserve Fund and made in accordance
with this Section 3.05. The Carryover Reserve Fund will not constitute an
asset of any REMIC created hereunder. The Class C Certificates shall evidence
ownership of the Carryover Reserve Fund for federal tax purposes.

            (h) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Pre-funding Account. On the Closing Date Countrywide
shall remit the Pre-funded Amount to the Trustee for deposit in the
Pre-funding Account. On each Supplemental Transfer Date, upon satisfaction of
the conditions for such Supplemental Transfer Date set forth in Section
2.01(e), with respect to the related Supplemental Transfer Agreement, the
Trustee shall pay to each Seller selling Supplemental Mortgage Loans to the
Depositor on such Supplemental Transfer Date the portion of the Aggregate
Supplemental Transfer Amount held in escrow pursuant to Section 2.01(e) as
payment of the purchase price for the Supplemental Mortgage Loans sold by such
Seller. If at any time the Depositor becomes aware that the aggregate Cut-off
Date Stated Principal Balance of Supplemental Mortgage Loans reflected on any
Supplemental Transfer Agreement exceeds the actual aggregate Cut-off Date
Stated Principal Balance of the relevant Supplemental Mortgage Loans, the
Depositor may so notify the Trustee and the Trustee shall redeposit into the
Pre-funding Account the excess reported to it by the Depositor.

      If any funds remain in the Pre-funding Account at the end of the Funding
Period, to the extent that they represent earnings on the amounts originally
deposited into the Pre-funding Account, the Trustee shall distribute them to
the order of the Depositor. The remaining funds shall be transferred to the
Distribution Account to be included as part of the Principal Remittance Amount
for each Loan Group.

            (i) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Capitalized Interest Account. On the Closing Date,
Countrywide shall remit the aggregate Capitalized Interest Requirement to the
Trustee for deposit in the Capitalized Interest Account. On each Distribution
Account Deposit Date related to a Funding Period Distribution Date, upon
satisfaction of the conditions for such Supplemental Transfer Date set forth
in Section 2.01(e), with respect to the related Supplemental Transfer
Agreement, the Trustee shall transfer from the Capitalized Interest Account to
the Distribution Account an amount equal to the Capitalized Interest
Requirement (which, to the extent required, may include investment earnings on
amounts on deposit therein) with respect to the amount remaining in the
Pre-funding Account for the related Distribution Date as identified by
Countrywide in the Supplemental Transfer Agreement.

      If any funds remain in the Capitalized Interest Account at the end of
the Funding Period, the Trustee shall make the transfer described in the
preceding paragraph if necessary for the


                                      75
<PAGE>


remaining Funding Period Distribution Date and the Trustee shall distribute
any remaining funds in the Capitalized Interest Account to the order of the
Depositor.

      SECTION 3.06.      Collection of Taxes, Assessments and Similar Items;
                        Escrow Accounts.

      (a) To the extent required by the related Mortgage Note and not
violative of current law, the Master Servicer shall establish and maintain one
or more accounts (each, an "Escrow Account") and deposit and retain therein
all collections from the Mortgagors (or advances by the Master Servicer) for
the payment of taxes, assessments, hazard insurance premiums or comparable
items for the account of the Mortgagors. Nothing in this Agreement shall
require the Master Servicer to compel a Mortgagor to establish an Escrow
Account in violation of applicable law.

      (b) Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to
reimburse the Master Servicer out of related collections for any payments made
pursuant to Sections 3.01 (with respect to taxes and assessments and insurance
premiums) and 3.09 (with respect to hazard insurance), to refund to any
Mortgagors any sums determined to be overages, to pay interest, if required by
law or the terms of the related Mortgage or Mortgage Note, to Mortgagors on
balances in the Escrow Account or to clear and terminate the Escrow Account at
the termination of this Agreement in accordance with Section 9.01. The Escrow
Accounts shall not be a part of the Trust Fund.

      (c) The Master Servicer shall advance any payments referred to in
Section 3.06(a) that are not timely paid by the Mortgagors on the date when
the tax, premium or other cost for which such payment is intended is due, but
the Master Servicer shall be required so to advance only to the extent that
such advances, in the good faith judgment of the Master Servicer, will be
recoverable by the Master Servicer out of Insurance Proceeds, Liquidation
Proceeds or otherwise.

      SECTION 3.07.      Access to Certain Documentation and Information
                         Regarding the Mortgage Loans.

      The Master Servicer shall afford each Seller, the Depositor, the NIM
Insurer and the Trustee reasonable access to all records and documentation
regarding the Mortgage Loans and all accounts, insurance information and other
matters relating to this Agreement, such access being afforded without charge,
but only upon reasonable request and during normal business hours at the
office designated by the Master Servicer.

      Upon reasonable advance notice in writing, the Master Servicer will
provide to each Certificateholder and/or Certificate Owner which is a savings
and loan association, bank or insurance company certain reports and reasonable
access to information and documentation regarding the Mortgage Loans
sufficient to permit such Certificateholder and/or Certificate Owner to comply
with applicable regulations of the OTS or other regulatory authorities with
respect to investment in the Certificates; provided that the Master Servicer
shall be entitled to be reimbursed by each such Certificateholder and/or
Certificate Owner for actual expenses incurred by the Master Servicer in
providing such reports and access. Upon request, the Master Servicer


                                      76
<PAGE>


shall furnish to the Trustee and the NIM Insurer its most recent publicly
available financial statements and any other information relating to its
capacity to perform its obligations under this Agreement reasonably requested
by the NIM Insurer.

      SECTION 3.08.      Permitted Withdrawals from the Certificate Account,
                        the Distribution Account, the Carryover Reserve Fund
                        and the Principal Reserve Fund.

      (a) The Master Servicer may from time to time make withdrawals from the

      as additional servicing compensation, earnings on or investment income
      with respect to funds in or credited to the Certificate Account;

      Section 3.01 or Section 3.06 and (b) for unpaid Master Servicing Fees as
      provided in Section 3.11;

            (vi) to pay to the purchaser, with respect to each Mortgage Loan

Nonrecoverable Advance and identifying the related Mortgage Loans(s), and
their respective portions of such Nonrecoverable Advance.

      (b) The Trustee shall withdraw funds from the Distribution Account for

      (d) On the Business Day before the Class P Principal Distribution Date,
the Trustee shall transfer $100.00 from the Principal Reserve Fund to the
Distribution Account and shall distribute such amount to the Class P

distributions to be made in accordance with the preceding sentence, the
Trustee shall then terminate the Principal Reserve Fund.

      SECTION 3.09.      Maintenance of Hazard Insurance; Maintenance of
                        Primary Insurance Policies.

       (a) The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan or (ii) the greater of (y) the outstanding
principal balance of the Mortgage Loan and (z) an amount such that the
proceeds of such policy shall be sufficient to prevent the Mortgagor and/or
the mortgagee from becoming a co-insurer. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. Any amounts collected by the Master Servicer under
any such policies (other than the amounts to be applied to the restoration or
repair of the related Mortgaged Property or amounts released to the Mortgagor
in accordance with the Master Servicer's normal servicing procedures) shall be
deposited in the Certificate Account. Any cost incurred by the Master Servicer
in maintaining any such insurance shall not, for the purpose of calculating
monthly distributions to the Certificateholders or remittances to the Trustee
for their benefit, be added to the principal balance of the Mortgage Loan,
notwithstanding that the terms of the Mortgage Loan so permit. Such costs
shall be recoverable by the Master Servicer out of late payments by the
related Mortgagor or out of proceeds of liquidation of the Mortgage Loan or
Subsequent Recoveries to the extent permitted by Section 3.08. It is
understood and agreed that no earthquake or other additional insurance is to
be required of any Mortgagor or maintained on property acquired in respect of
a Mortgage other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance.
If the Mortgaged Property is located at the time of origination of the
Mortgage Loan in a federally designated special flood hazard area and such
area is participating in the national flood insurance program, the Master
Servicer shall cause flood insurance to be maintained with respect to such
Mortgage Loan. Such flood insurance shall be in an amount equal to the least
of (i) the outstanding principal balance of the related Mortgage Loan, (ii)
the replacement value of the improvements which are part of such Mortgaged
Property, and (iii) the maximum amount of such insurance available for the
related Mortgaged Property under the national flood insurance program.

      (b)    [Reserved].


                                      79
<PAGE>


      (c) The Master Servicer shall not take any action which would result in
non-coverage under any applicable Primary Insurance Policy of any loss which,
but for the actions of the Master Servicer, would have been covered
thereunder. The Master Servicer shall not cancel or refuse to renew any such
Primary Insurance Policy that is in effect at the date of the initial issuance
of the Certificates and is required to be kept in force hereunder unless the
replacement Primary Insurance Policy for such canceled or non-renewed policy
is maintained with a Qualified Insurer.

      Except with respect to any Lender PMI Mortgage Loans, the Master
Servicer shall not be required to maintain any Primary Insurance Policy (i)
with respect to any Mortgage Loan with a Loan-to-Value Ratio less than or
equal to 80% as of any date of determination or, based on a new appraisal, the
principal balance of such Mortgage Loan represents 80% or less of the new
appraised value or (ii) if maintaining such Primary Insurance Policy is
prohibited by applicable law. With respect to the Lender PMI Mortgage Loans,
the Master Servicer shall maintain the Primary Insurance Policy for the life
of such Mortgage Loans, unless otherwise provided for in the related Mortgage
Note or prohibited by law.

      The Master Servicer agrees to effect the timely payment of the premiums
on each Primary Insurance Policy, and such costs not otherwise recoverable
shall be recoverable by the Master Servicer from the related proceeds of
liquidation and Subsequent Recoveries.

      (d) In connection with its activities as Master Servicer of the Mortgage
Loans, the Master Servicer agrees to present on behalf of itself, the Trustee
and Certificateholders, claims to the insurer under any Primary Insurance
Policies and, in this regard, to take such reasonable action as shall be
necessary to permit recovery under any Primary Insurance Policies respecting
defaulted Mortgage Loans. Any amounts collected by the Master Servicer under
any Primary Insurance Policies shall be deposited in the Certificate Account.

      SECTION 3.10.      Enforcement of Due-on-Sale Clauses; Assumption
                        Agreements.

      (a) Except as otherwise provided in this Section, when any property
subject to a Mortgage has been conveyed by the Mortgagor, the Master Servicer
shall to the extent that it has knowledge of such conveyance, enforce any
due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent
permitted under applicable law and governmental regulations, but only to the
extent that such enforcement will not adversely affect or jeopardize coverage
under any Required Insurance Policy. Notwithstanding the foregoing, the Master
Servicer is not required to exercise such rights with respect to a Mortgage
Loan if the Person to whom the related Mortgaged Property has been conveyed or
is proposed to be conveyed satisfies the terms and conditions contained in the
Mortgage Note and Mortgage related thereto and the consent of the mortgagee
under such Mortgage Note or Mortgage is not otherwise so required under such
Mortgage Note or Mortgage as a condition to such transfer. In the event that
the Master Servicer is prohibited by law from enforcing any such due-on-sal
