(5)   The interest rate for this REMIC 1 Interest with respect to any
      Distribution Date (and the related Accrual Period) through the
      Distribution Date in June 2005 is a per annum rate equal to the weighted
      average of the Adjusted Net Mortgage Rates of the Initial Mortgage Loans
      in the Corresponding Loan Group. For any Distribution Date (and the
      related Accrual Period) following the Distribution Date in June 2005,

      Distribution Date in June 2005, the interest rate for this REMIC 1
      Interest is a per annum rate equal to 0.00%.

      On each Distribution Date, the Interest Funds and the Principal
Distribution Amount of the Corresponding Loan Groups shall be distributed with
respect to the REMIC 1 Interests in the following manner:

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

      (2) Principal For any Distribution Date (and the related Accrual Period)
through the Distribution Date in June 2005, the Principal Distribution Amount
with respect to the Initial Mortgage Loans in a Loan Group shall be allocated

(1)   The Class F Interest will have a principal balance equal to the
      principal balance of the R-1-1-I and R-1-1-S Interests.

(2)   A rate equal to the weighted average of the pass-through rates of the
      R-1-1-I and R-1-1-S Interests (the "Loan Group 1 Net Rate Cap").

(3)   With respect to the Variable Interests, each REMIC 2 Interest having an
      "R-2-A-" designation (each, an "R-2-A Interest") will have a principal
      balance initially equal to 0.9% of the Subordinate Component Balance
      ("SCB") of its Corresponding Loan Group. Each REMIC 1 Interest having an
      "R-2-B-" designation (each, an "R-2-B Interest") will have a principal
      balance initially equal to 0.1% of the SCB of its Corresponding Loan
      Group. Each REMIC 2 Interest having an "R-2-C-" designation (each, an
      "R-2-C Interest") will have a principal balance initially equal to 0.9%
      of the Adjusted Subordinated Component Balance ("ASCB") of its
      Corresponding Loan Group. Each REMIC 2 Interest having an "R-2-D-"
      designation (each, an "R-2-D Interest") will have a principal balance
      initially equal to 0.1% of the ASCB of its Corresponding Loan Group. The
      initial principal balance of each REMIC 2 Interest having an "R-2-E-"
      designation (each, an "R-2-E Interest") will equal the excess of its
      Corresponding Loan Group over the initial aggregate principal balances
      of the R-2-A, R-2-B, R-2-C and R-2-D Interests corresponding to such
      Loan Group.

(4)   A rate equal to the weighted average of the pass-through rates of the
      R-1-2-I and R-1-2-S Interests (the "Loan Group 2 Net Rate Cap").

(5)   A rate equal to the weighted average of the pass-through rates of the
      R-1-3-I and R-1-3-S Interests (the "Loan Group 3 Net Rate Cap").

(6)   A rate equal to the weighted average of the pass-through rates of the
      R-1-4-I and R-1-4-S Interests (the "Loan Group 4 Net Rate Cap").

(7)   The R-2-PF Interest is entitled to all Prepayment Charges collected with
      respect to the Mortgage Loans in Group 1. It pays no interest.

(8)   The R-2-PV Interest is entitled to all Prepayment Charges collected with
      respect to the Mortgage Loans in Loan Group 2, Loan Group 3 and Loan
      Group 4. It pays no interest.

(9)   The R-2-R Interest is the sole class of residual interest in REMIC 2. It
      has no principal balance and pays no principal or interest.

(10)  This REMIC 2 Interest pays no principal.

                                       4

(11)  This REMIC 2 Interest is entitled to all amounts payable with respect to
      the R-1-XF Interest.

(12)  This REMIC 2 Interest is entitiled to all amounts payable with respect
      to the R-1-XV Interest.

            On each Distribution Date, the Interest Funds and the Principal
Distribution Amounts payable with respect to the REMIC 1 Interests shall be
payable with respect to the REMIC 2 Interests in the following manner:

      (1) Interest. Interest is to be distributed with respect to each REMIC 2
Interest at the rate, or according to the formulas, described above.

      (2) Principal. All Principal Distribution Amounts arising with respect
to Loan Group 1 shall be allocated to the Fixed Interests.

      (3) Principal if no Cross-Over Situation Exists. If no Cross-Over
Situation exists with respect to any Variable Interest, then the Principal
Distribution Amounts payable with respect to each Variable Loan Group will be
payable: first to cause the Variable Loan Group's corresponding R-2-A, R-2-B,
R-2-C and R-2-D Interests to equal, respectively, 0.9% of the SCB, 0.1% of the
SCB, 0.9% of the ASCB and 0.1% of the ASCB, of the Corresponding Loan Group,
and then to the corresponding R-2-E Interest.

      (4) Principal if a Cross-Over Situation Exists. If a Cross-Over
Situation exists with respect to the R-2-A and R-2-B Interests then:

      (a) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is less than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-A Interests prior to any other principal distributions from each such
Variable Loan Group; and

      (b) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is greater than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-B Interests prior to any other principal distributions from each such
Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-A and R-2-B Interests to
equal the Adjustable Rate Subordinate Net Rate Cap. With respect to each
Variable Loan Group, if (and to the extent that) the sum of (a) the principal
payments comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-A and R-2-B Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.

(c) The outstanding aggregate R-2-A and R-2-B Interests for the Variable Loan
Groups will not be reduced below 1 percent of the excess of (i) the aggregate
outstanding Stated Principal Balances of all Variable Loan Groups as of the
end of any Due Period over (ii) the Senior

                                       5
<PAGE>

Certificates related to the Variable Loan Groups as of the related
Distribution Date (after taking into account distributions of principal on
such Distribution Date).

If (and to the extent that) the limitation in paragraph (c) prevents the
distribution of principal to the R-2-A and R-2-B Interests of a Variable Loan
Group, and if the Variable Loan Group's corresponding R-2-E Interest has
already been reduced to zero, then the excess principal from that Variable
Loan Group will be paid to the R-2-E Interest of the other Variable Loan
Groups, the aggregate R-2-A and R-2-B Interests of which are less than one
percent of the Subordinate Component Balance. If the Variable Loan Group of
the corresponding R-2-E Interest that receives such payment has a Group Net
Rate Cap below the Group Net Rate Cap of the Variable Loan Group making the
payment, then the payment will be treated by REMIC 2 as a Realized Loss.
Conversely, if the Variable Loan Group of the R-2-E Interest that receives
such payment has a Group Net Rate Cap above the Group Net Rate Cap of the
Variable Loan Group making the payment, then the payment will be treated by
REMIC 2 as a reimbursement for prior Realized Losses.

If a Cross-Over Situation exists with respect to the R-2-C and R-2-D Interests
then:

      (d) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is less than the Modified Adjustable Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the R-2-C
Interests prior to any other principal distributions from each such Variable
Loan Group; and

      (e) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is greater than the Modified Adjustable Subordinate Net Rate
Cap, Principal Relocation Payments will be made proportionately to the
outstanding R-2-D Interests prior to any other principal distributions from
each such Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-C and R-2-D Interests to
equal the Modified Adjustable Subordinate Net Rate Cap. With respect to each
Variable Loan Group, if (and to the extent that) the sum of (a) the principal
payments comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-C and R-2-D Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.

      (f) The outstanding aggregate R-2-C and R-2-D Interests for all Variable
Loan Groups will not be reduced below 1 percent of the excess of (i) the
aggregate outstanding Stated Principal Balances of all Variable Loan Groups as
of the end of any Due Period over (ii) the Senior Certificates related to the
Variable Loan Groups as of the related Distribution Date (after taking into
account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (f) prevents the
distribution of principal to the R-2-C and R-2-D Interests of a Variable Loan
Group, and if the Variable Loan Group's R-2-E Interest has already been
reduced to zero, then the excess principal from that Variable Loan Group will
be paid to the R-2-E Interests of the other Variable Loan Groups, the
aggregate R-2-C and R-2-D Interests of which are less than one percent of the
Adjusted Subordinate

                                       6
<PAGE>

Component Balance. If the Variable Loan Group of the R-2-E Interest that
receives such payment has a Group Net Rate Cap below the Group Net Rate Cap of
the Variable Loan Group making the payment, then the payment will be treated
by REMIC 2 as a Realized Loss. Conversely, if the Variable Loan Group of the
R-2- E Interest that receives such payment has a Group Net Rate Cap above the
Group Net Rate Cap of the Variable Loan Group making the payment, then the
payment will be treated by REMIC 2 as a reimbursement for prior Realized
Losses.

50% of its Corresponding Certificate Class issued by the Master REMIC.
Principal payments, both scheduled and prepaid, Realized Losses, Subsequent
Recoveries and interest accruing on the R-3-F-Accrual Interest will be
allocated to this class to maintain its size relative to its Corresponding
Certificate Class (that is, 50%) with any excess payments of principal,
Realized Losses and Subsequent Recoveries being allocated to the R-3-F-Accrual
Interest in such manner as to cause the principal balance of the R-3-F-Accrual
Interest to have a principal balance equal to (a) 50% of the Loan Group 1
principal balance plus (b) 50% of the Fixed Rate Overcollateralized Amount for
such Distribution Date.

(2) The pass-through rate with respect to any Distribution Date (and the
related Accrual Period) for this REMIC 3 Interest is a per annum rate equal to

(1)   The Certificates will accrue interest at the related Pass-Through Rates
      identified in this Agreement. For federal income tax purposes, the pass
      through rate in respect of (i) each of the Class AF (other than the
      Class AF-5B Certificates), Class MF and Class BF Certificates will be
      subject to a cap equal to the Loan

                                      11
<PAGE>

      Group 1 Net Rate Cap, (ii) the Class AF-5B Certificates will be subject
      to a cap equal to the Loan Group 1 Net Rate Cap minus the Class AF-5B
      Policy Premium Rate), (iii) the Class 1-AV-1 Certificates will be
      subject to a cap equal to the Loan Group 2 Net Rate Cap, (iv) the Class
      2-AV Certificates will be subject to a cap equal to the Loan Group 3 Net
      Rate Cap, (v) the Class 3-AV Certificates will be subject to a cap equal
      to the Loan Group 4 Net Rate Cap and (vi) the Class MV Certificates and
      the Class BV Certificates will be subject to a cap equal to the Modified
      Adjustable Subordinate Net Rate Cap. Any entitlement of any class of
      Certificates to Net Rate Carryover will be treated as paid by the Master
      REMIC to the Class CF Certificates, in the case of the Class AF
      Certificates, the Class MF Certificates and the Class BF Certificates,
      and to the Class CV Certificates, in the case of the Class AV
      Certificates, the Class MV Certificates and the Class BV Certificates,
      and then paid to such Class of Certificates pursuant to a limited
      recourse cap contract as described in Section 8.11 herein.
(2)   The Class CF and Class CV Certificates will have Certificate Principal
      Balances equal to the Fixed Rate Overcollateralized Amount and
      Adjustable Rate Overcollateralized Amount, respectively.
(3)   For each Interest Accrual Period the Class CF Certificates are entitled
      to an amount (the "Class CF Distributable Amount") equal to the sum of
      (a) the interest payable on the R-3-XF Interests and (b) a specified
      portion of the interest on the REMIC 1 Group 1 "I" and "S" Interests
      equal to the excess of the Loan Group 1 Net Rate Cap over the product of
      two and the weighted average interest rate of the REMIC 3 Regular
      Interests having an "F" designated in the column entitled "REMIC 3
      Interests" (other than the R-3-PF and R-3-XF Interests) with each such
      Class other than the R-3-F-Accrual Interest, subject to a cap equal to
      the Pass-Through Rate of the Corresponding Master REMIC Class and the
      R-3-F-Accrual Interest subject to a cap of 0.00%. The Pass-Through Rate
      of the Class CF Certificates shall be a rate sufficient to entitle it to
      all interest accrued on the REMIC 1 Group 1 "I" and "S" Interests less
      the interest accrued on the other F Class interests issued by the Master
      REMIC. The Class CF Distributable Amount for any Distribution Date is
      payable from current interest on the Group 1 Mortgage Loans.
(4)   For each Interest Accrual Period the Class CV Certificates are entitled
      to an amount (the "Class CV Distributable Amount") equal to the sum of
      (a) the interest payable on the R-3-XV Interests and (b) a specified
      portion of the interest on the REMIC 1 Group 2, Group 3 and Group 4 "I"
      and "S" Interests equal to the excess of the Loan Group 2/3/4 Net Rate
      Cap over the product of two and the weighted average interest rate of
      the REMIC 3 Regular Interests having an "V" designated in the column
      entitled "REMIC 3 Interests" (other than the R-3-PV and R-3-XV
      Interests) with each such Class other than the R-3-V-Accrual Interest,
      subject to a cap equal to the Pass-Through Rate of the Corresponding
      Master REMIC Class and the R-3-V-Accrual Interest subject to a cap of
      0.00%. The Pass-Through Rate of the Class CV Certificates shall be a
      rate sufficient to entitle it to all interest accrued on the REMIC 1
      Group 2, Group 3 and Group 4 "I" and "S" Interests less the interest
      accrued on the other V Class interests issued by the Master REMIC. The
      Class CV Distributable Amount for any Distribution Date is payable from
      current interest on the Group 2, Group 3 and Group 4 Mortgage Loans.
(5)   For each Distribution Date the Class PF and Class PV Certificates are
      entitled to all Prepayment Charges distributed with respect to the
      R-3-PF and R-3-PV Interests, respectively.
(6)   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 a REMIC
regular interest, without 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 be entitled to any cash flows pursuant to this agreement except
as provided in Sections 3.08(a) hereunder, (that is, its entitlement to $100).

                        REPRESENTATIONS AND WARRANTIES

            Section 2.01      Conveyance of Mortgage Loans.

            (a)   Each Seller hereby sells, transfers, assigns, sets over and
otherwise conveys to the Depositor, without recourse, all the right, title and
interest of such Seller in and to the applicable Initial Mortgage Loans,
including all interest and principal received and receivable by such Seller on
or with respect to applicable Initial Mortgage Loans after the Initial 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 Master
Servicer on behalf of such Seller as part of the Initial Certificate Account
Deposit as provided in this Agreement, other than principal due on the
applicable Initial Mortgage Loans on or prior to the Initial Cut-off Date and
interest accruing prior to the Initial Cut-off Date. The Master Servicer
confirms that, on behalf of the Sellers, concurrently with the transfer and
assignment, it has deposited into the Certificate Account the Initial
Certificate Account Deposit.

            Immediately upon the conveyance of the Initial Mortgage Loans
referred to in the preceding paragraph, the Depositor (i) sells, transfers,
assigns, sets over and otherwise conveys to the Trustee for benefit of the
Certificateholders and the Class AF-5B Insurer, without recourse, all right
title and interest in the Initial Mortgage Loans and (ii) causes the Class
AF-5B Insurer to deliver the Class AF-5B Policy to the Trustee.

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

            (b)   Subject to the execution and delivery of the related
Subsequent Transfer Agreement as provided by Section 2.01(d) 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 Subsequent
Transfer Date, all the right, title and interest of such Seller in and to the
related Subsequent Mortgage Loans, including all interest and principal
received and receivable by such Seller on or with respect to such Subsequent
Mortgage Loans after the related

                                      64
<PAGE>

Subsequent 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 Master Servicer on behalf of such Seller as part of any related Subsequent
Certificate Account Deposit as provided in this Agreement, other than
principal due on such Subsequent Mortgage Loans on or prior to the related
Subsequent Cut-off Date and interest accruing prior to the related Subsequent
Cut-off Date.

            Immediately upon the conveyance of the Subsequent 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 and the Class AF-5B Insurer, without recourse, all right
title and interest in the Subsequent Mortgage Loans.

            (c)   Each Seller has entered into this Agreement in consideration
for the purchase of the Mortgage Loans by 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 Trustee pursuant to Section 2.01(a) or (b).

            (d)   On any Business Day during the Funding Period designated by
CHL to the Trustee, the Sellers, the Depositor and the Trustee shall complete,
execute and deliver a Subsequent Transfer Agreement. After the execution and
delivery of such Subsequent Transfer Agreement, on the Subsequent Transfer
Date, the Trustee shall set aside in the Pre-Funding Account an amount equal
to the related Subsequent Transfer Date Purchase Amount.

            (e)   The transfer of Subsequent Mortgage Loans on the Subsequent
Transfer Date is subject to the satisfaction of each of the following
conditions:

                  (1)   the Trustee and the Underwriters will be provided
      Opinions of Counsel addressed to the Rating Agencies as with respect to
      the sale of the Subsequent Mortgage Loans conveyed on such Subsequent
      Transfer Date (such opinions being substantially similar to the opinions
      delivered on the Closing Date to the Rating Agencies with respect to the
      sale of the Initial Mortgage Loans on the Closing Date), to be delivered
      as provided in Section 2.01(f);

                  (2)   the execution and delivery of such Subsequent Transfer
      Agreement or conveyance of the related Subsequent Mortgage Loans does
      not result in a reduction or withdrawal of the ratings assigned to the
      Certificates by the Ratings Agencies (without regard to the Class AF-5B
      Policy, in the case of the Class AF-5B Certificates);

                  (3)   the Depositor shall deliver to the Trustee an
      Officer's Certificate confirming the satisfaction of each of the
      conditions set forth in this Section 2.01(e) required to be satisfied by
      such Subsequent Transfer Date;

                  (4)   each Subsequent Mortgage Loan conveyed on such
      Subsequent 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
      Subsequent Mortgage Loan set forth in this clause (4), the

                                      65
<PAGE>

      obligation under Section 2.03(d) of this Agreement of the applicable
      Seller, to cure, repurchase or replace such Subsequent Mortgage Loan
      shall constitute the sole remedy against such Seller respecting such
      breach available to Certificateholders, the Depositor or the Trustee;

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

                  (6)   no Subsequent Mortgage Loan conveyed on such
      Subsequent Transfer Date was 30 or more days delinquent;

                  (7)   following the conveyance of the Subsequent Mortgage
      Loans on such Subsequent Transfer Date, the characteristics of each Loan
      Group will not vary by more than the amount specified below (other than
      the percentage of Mortgage Loans secured by Mortgaged Properties located
      in the State of California, which will not exceed 50% of the Mortgage
      Pool and the percentage of mortgage loans in the Credit Grade Categories
      of "C" or below, which will not exceed 10% of the Mortgage Loans in each
      Loan Group) from the characteristics listed below; provided that for the
      purpose of making such calculations, the characteristics for any Initial
      Mortgage Loan made will be taken as of the Initial Cut-off Date and the
      characteristics for any Subsequent Mortgage Loans will be taken as of
      the Subsequent Cut-off Date;

      expense of either the Trustee or the Trust Fund, addressed to the
      Trustee, to the effect that such purchase of Subsequent Mortgage Loans

2.01(d). The positive difference, if any, between the Subsequent Transfer Date
Transfer Amount and the Subsequent Transfer Date Purchase Amount shall be
re-invested by the Trustee in the Pre-Funding Account.

            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 each Subsequent 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 Subsequent
Mortgage Loans conveyed on such Subsequent Transfer Date conform to the

            (g)   In connection with the transfer and assignment of each
Mortgage Loan, the Depositor has delivered to, and deposited with, the
Co-Trustee (or, in the case of the Delay Delivery Mortgage Loans, will deliver
to, and deposit with, the Co-Trustee within the time periods specified in the
definition of Delay Delivery Mortgage Loans) (except as provided in clause
(vi) below) for the benefit of the Certificateholders, the following documents
or instruments with respect to each such Mortgage Loan so assigned (with
respect to each Mortgage Loan, clause (i) through (vi) below, together, the
"Mortgage File" for each such Mortgage Loan):

                  (i)   the original Mortgage Note, endorsed by manual or

            endorsements that show 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, if the original
            Mortgage Note has been lost or destroyed and not replaced, an
            original lost note affidavit, stating that the original Mortgage
            Note was lost or destroyed, together with a copy of the related
            Mortgage Note;

                  (ii)  in the case of each Mortgage Loan that is not a MERS
            Mortgage Loan, the original recorded Mortgage, and in the case of
            each MERS Mortgage Loan, the original Mortgage, noting the
            presence of the MIN of the Mortgage Loan and language indicating
            that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM
            Loan, 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 to
            "Asset-Backed Certificates, Series 2005-1, CWABS, Inc., by The
            Bank of New York, a New York banking corporation, as trustee under
            the Pooling and Servicing Agreement dated as of March 1, 2005,
            without recourse" (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 such assignment relates);

                  (iv)  the original recorded assignment or assignments of the
            Mortgage together with all interim recorded assignments of such
            Mortgage (noting the presence of a MIN in the case of each MERS
            Mortgage Loan);

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

                  (vi) the original or duplicate original lender's title
            policy or a printout of the electronic equivalent and all riders
            thereto or, in the event such original title policy has not been
            received from the insurer, such original or duplicate original
            lender's title policy and all riders thereto shall be delivered
            within one year of the Closing Date.

            In addition, in connection with the assignment of any MERS
Mortgage Loan, each Seller agrees that it will cause, at such Seller's own
expense, the MERS(R) System to indicate (and provide evidence to the Trustee
that it has done so) that such Mortgage Loans have been assigned by such
Seller to the Trustee in accordance with this Agreement 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 (a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY
THE FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such
Mortgage Loans. The Sellers further agree that they will not, and will not
permit the Master Servicer to, and the Master Servicer agrees that it will
not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan 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 a Seller cannot deliver the original recorded Mortgage or
all interim recorded

                                      69
<PAGE>

assignments of the Mortgage satisfying the requirements of clause (ii), (iii)
or (iv) concurrently with the execution and delivery hereof, such Seller shall
deliver or cause to be delivered to the Co-Trustee a true copy of such
Mortgage and of each such undelivered interim assignment of the Mortgage each
certified by such Seller, the applicable title company, escrow agent or
attorney, or the originator of such Mortgage, as the case may be, to be a true
and complete copy of the original Mortgage or assignment of Mortgage submitted
for recording. For any such Mortgage Loan that is not a MERS Mortgage Loan
each Seller shall promptly deliver or cause to be delivered to the Co-Trustee
such original Mortgage and such assignment or assignments with evidence of
recording indicated thereon upon receipt thereof from the public recording
official, or a copy thereof, certified, if appropriate, by the relevant
recording office, but in no event shall any such delivery be made later than
270 days following the Closing Date; provided that in the event that by such
date such Seller is unable to deliver or cause to be delivered each such
Mortgage and each 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 interim assignment, because the related Mortgage has not been
returned by the appropriate recording office, such Seller shall deliver or
cause to be delivered such documents to the Co-Trustee as promptly as possible
upon receipt thereof. If the public recording office in which a Mortgage or
interim assignment thereof is recorded retains the original of such Mortgage
or assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall satisfy a Seller's obligations in Section 2.01. If any
document submitted for recording pursuant to this Agreement is (x) lost prior
to recording or rejected by the applicable recording office, the applicable
Seller shall immediately prepare or cause to be prepared a substitute and
submit it for recording, and shall deliver copies and originals thereof in
accordance with the foregoing or (y) lost after recording, the applicable
Seller shall deliver to the Co-Trustee a copy of such document certified by
the applicable public recording office to be a true and complete copy of the
original recorded document. Each Seller shall promptly forward or cause to be
forwarded to the Co-Trustee (x) from time to time additional original
documents evidencing an assumption or modification of a Mortgage Loan and (y)
any other documents required to be delivered by the Depositor or the Master
Servicer to the Co-Trustee within the time periods specified in this Section
2.01.

            With respect to each Mortgage Loan other than a MERS Mortgage Loan
as to which the related Mortgaged Property and Mortgage File are located in
(a) the State of California or (b) any other jurisdiction under the laws of
which the recordation of the assignment specified in clause (iii) above 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 CHL
to the Trustee and a copy to the Rating Agencies, in lieu of recording the
assignment specified in clause (iii) above, the applicable Seller may deliver
an unrecorded assignment in blank, in form otherwise suitable for recording to
the Co-Trustee; provided that if the related Mortgage has not been returned
from the applicable public recording office, such assignment, or any copy
thereof, of the Mortgage may exclude the information to be provided by the
recording office. As to any Mortgage Loan other than a MERS Mortgage Loan, the
procedures of the preceding sentence shall be applicable only so long as the
related Mortgage File is maintained in the possession of the Co-Trustee in the
State or jurisdiction described in such sentence. In the event that with
respect to Mortgage Loans other than MERS Mortgage Loans (i) any Seller, the
Depositor, the Master Servicer or the NIM Insurer gives written notice to the
Trustee that recording is required to protect the right, title and interest of
the Trustee on behalf of the Certificateholders in and to

                                      70

any Mortgage Loan, (ii) a court recharacterizes any sale of the Mortgage Loans
as a financing, or (iii) as a result of any change in or amendment to the laws
of the State or jurisdiction described in the first sentence of this paragraph
or any applicable political subdivision thereof, or any change in official
position regarding application or interpretation of such laws, including a
holding by a court of competent jurisdiction, such recording is so required,
the Co-Trustee shall complete the assignment in the manner specified in clause
(iii) of the second paragraph of this Section 2.01(g) and CHL shall submit or
cause to be submitted for recording as specified above or, should CHL fail to
perform such obligations, the Trustee shall cause the Master Servicer, at the
Master Servicer's expense, to cause each such previously unrecorded assignment
to be submitted for recording as specified above. In the event a Mortgage File
is released to the Master Servicer as a result of the Master Servicer's having
completed a Request for Document Release, the Trustee shall complete the
assignment of the related Mortgage in the manner specified in clause (iii) of
the second paragraph of this Section 2.01(g).

            So long as the Co-Trustee or its agent maintains an office in the
State of California, the Co-Trustee or its agent shall maintain possession of
and not remove or attempt to remove from the State of California any of the
Mortgage Files as to which the related Mortgaged Property is located in such
State. In the event that a Seller fails to record an assignment of a Mortgage
Loan as herein provided within 90 days of notice of an event set forth in
clause (i), (ii) or (iii) of the above paragraph, the Master Servicer shall
prepare and, if required hereunder, file such assignments for recordation in
the appropriate real property or other records office. Each Seller hereby
appoints the Master Servicer (and any successor servicer hereunder) as its
attorney-in-fact with full power and authority acting in its stead for the
purpose of such preparation, execution and filing.

            In the case of Mortgage Loans that become the subject of a
Principal Prepayment between the Closing Date (in the case of Initial Mortgage
Loans) or related Subsequent Transfer Date (in the case of Subsequent Mortgage
Loans) and the Cut-off Date, CHL shall deposit or cause to be deposited in the
Certificate Account the amount required to be deposited therein with respect
to such payment pursuant to Section 3.05 hereof.

            Notwithstanding anything to the contrary in this Agreement, within
thirty days after the Closing Date (in the case of Initial Mortgage Loans) or
within twenty days after the related Subsequent Transfer Date (in the case of
Subsequent Mortgage Loans), CHL (on behalf of each Seller) shall either (i)
deliver to the Co-Trustee the Mortgage File as required pursuant to this
Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase the
Delay Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage
Loan for a Replacement Mortgage Loan, which repurchase or substitution shall
be accomplished in the manner and subject to the conditions set forth in
Section 2.03, provided that if CHL fails to deliver a Mortgage File for any
Delay Delivery Mortgage Loan within the period provided in the prior sentence,
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 CHL shall have five (5) Business Days to cure such
failure to deliver. CHL shall promptly provide each Rating Agency with written
notice of any cure, repurchase or substitution made pursuant to the proviso of
the preceding sentence. On or before the thirtieth (30th) day (or if such
thirtieth day is not a Business Day, the succeeding Business Day) after the
Closing Date (in the case of Initial Mortgage Loans) or within twenty days
after the related Subsequent Transfer Date (in the

                                      71
<PAGE>

case of Subsequent Mortgage Loans), the Trustee shall, in accordance with the
provisions of Section 2.02, send a Delay Delivery Certification substantially
in the form annexed hereto as Exhibit G-3 (with any applicable exceptions
noted thereon) for all Delay Delivery Mortgage Loans delivered within thirty
(30) days after such date. The Trustee will promptly send a copy of such Delay
Delivery Certification to each Rating Agency.

            Section 2.02      Acceptance by Trustee of the Mortgage Loans.

            (a)   The Co-Trustee acknowledges receipt, subject to the
limitations contained in and any exceptions noted in the Initial Certification
in the form annexed hereto as Exhibit G-1 and in the list of exceptions
attached thereto, of the documents referred to in clauses (i) and (iii) of
Section 2.01(g) above with respect to the Initial Mortgage Loans and all other
assets included in the Trust Fund 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 included in
the Trust Fund, in trust for the exclusive use and benefit of all present and
future Certificateholders.

            The Trustee agrees to execute and deliver on the Closing Date to
the Depositor, the Master Servicer and CHL (on behalf of each Seller) an
Initial Certification substantially in the form annexed hereto as Exhibit G-1
to the effect that, as to each Initial Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Initial Mortgage Loan paid in full or any
Initial Mortgage Loan specifically identified in such certification as not
covered by such certification), the documents described in Section 2.01(g)(i)
and, in the case of each Initial Mortgage Loan that is not a MERS Mortgage
Loan, the documents described in Section 2.01(g)(iii) with respect to such
Initial Mortgage Loans as are in the Co-Trustee's possession and based on its
review and examination and only as to the foregoing documents, such documents
appear regular on their face and relate to such Initial Mortgage Loan. The
Trustee agrees to execute and deliver within 30 days after the Closing Date to
the Depositor, the Master Servicer and CHL (on behalf of each Seller) an
Interim Certification substantially in the form annexed hereto as Exhibit G-2
to the effect that, as to each Initial Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Initial Mortgage Loan paid in full or any
Initial Mortgage Loan specifically identified in such certification as not
covered by such certification) all documents required to be delivered to the
Co-Trustee pursuant to the Agreement with respect to such Initial Mortgage
Loans are in its possession (except those documents described in Section
2.01(g)(vi)) and based on its review and examination and only as to the
foregoing documents, (i) such documents appear regular on their face and
relate to such Initial Mortgage Loan, and (ii) the information set forth in
items (i), (iv), (v), (vi), (viii), (ix) and (xvii) of the definition of the
"Mortgage Loan Schedule" accurately reflects information set forth in the
Mortgage File. On or before the thirtieth (30th) day after the Closing Date
(or if such thirtieth day is not a Business Day, the succeeding Business Day),
the Trustee shall deliver to the Depositor, the Master Servicer and CHL (on
behalf of each Seller) a Delay Delivery Certification with respect to the
Initial Mortgage Loans substantially in the form annexed hereto as Exhibit
G-3, with any applicable exceptions noted thereon. The Co-Trustee or the
Trustee, as applicable, shall be under no duty or obligation to inspect,
review or examine such 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.

            Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) and to any Certificateholder that so requests, a Final Certification
with respect to the Initial Mortgage Loans substantially in the form annexed
hereto as Exhibit H, with any applicable exceptions noted thereon.

            In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee, at the Trustee's direction, shall review
each Mortgage File with respect to the Initial Mortgage Loans to determine
that such Mortgage File contains the following documents:

                  (i)   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 that show 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, if the original
            Mortgage Note has been lost or destroyed and not replaced, an
            original lost note affidavit, stating that the original Mortgage
            Note was lost or destroyed, together with a copy of the related
            Mortgage Note;

                  (ii)  in the case of each Initial Mortgage Loan that is not
            a MERS Mortgage Loan, the original recorded Mortgage, and in the
            case of each Initial Mortgage Loan that is a MERS Mortgage Loan,
            the original Mortgage, noting the presence of the MIN of the
            Initial Mortgage Loan and language indicating that the Mortgage
            Loan is a MOM Loan if the Initial Mortgage Loan is a MOM Loan,
            with evidence of recording indicated thereon, or a copy of the
            Mortgage certified by the public recording office in which
            Mortgage has been recorded;

                  (iii) in the case of each Initial Mortgage Loan that is not
            a MERS Mortgage Loan, a duly executed assignment of the Mortgage
            in the form permitted by Section 2.01;

                  (iv)  the original recorded assignment or assignments of the
            Mortgage together with all interim recorded assignments of such
            Mortgage (noting the presence of a MIN in the case of each MERS
            Mortgage Loan);

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

                  (vi)  the original or duplicate original lender's title
            policy or a printout of the electronic equivalent and all riders
            thereto.

            If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not
meet the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall
include such exceptions in such Final Certification (and the Trustee shall
state in such Final Certification whether any Mortgage File does not then
include the original or duplicate original lender's title policy or a printout
of the electronic equivalent and all

                                      73

riders thereto). If the public recording office in which a Mortgage or
assignment thereof is recorded retains the original of such Mortgage or
assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall be deemed to satisfy the requirements of clause (ii),
(iii) or (iv) above, as applicable. CHL shall promptly correct or cure such
defect referred to above within 90 days from the date it was so notified of
such defect and, if CHL does not correct or cure such defect within such
period, CHL shall either (A) if the time to cure such defect expires prior to
the end of the second anniversary of the Closing Date, substitute for the
related Initial Mortgage Loan a Replacement 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 Initial Mortgage Loan from the Trust Fund
within 90 days from the date CHL was notified of such defect in writing at the
Purchase Price of such Initial Mortgage Loan; provided that any such
substitution pursuant to (A) above or repurchase 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 and any substitution pursuant to (A) above
shall not be effected prior to the additional delivery to the Co-Trustee of a
Request for File Release. No substitution will be made in any calendar month
after the Determination Date for such month. The Purchase Price for any such
Initial Mortgage Loan shall be deposited by CHL in the Certificate Account
and, upon receipt of such deposit and Request for File Release with respect
thereto, the Co-Trustee shall release the related Mortgage File to CHL and
shall execute and deliver at CHL's request such instruments of transfer or
assignment as CHL has prepared, in each case without recourse, as shall be
necessary to vest in CHL, or a designee, the Trustee's interest in any Initial
Mortgage Loan released pursuant hereto. If pursuant to the foregoing
provisions CHL repurchases an Initial Mortgage Loan that is a MERS Mortgage
Loan, the Master Servicer shall cause MERS to execute and deliver an
assignment of the Mortgage in recordable form to transfer the Mortgage from
MERS to CHL and shall cause such Mortgage to be removed from registration on
the MERS(R) System in accordance with MERS' rules and regulations.

            The Co-Trustee shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions set
forth herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of
such Seller from time to time.

            It is understood and agreed that the obligation of CHL to
substitute for or to purchase any Mortgage Loan that does not meet the
requirements of Section 2.02(a) above shall constitute the sole remedy
respecting such defect available to the Trustee, the Co-Trustee, the Depositor
and any Certificateholder against any Seller.

            It is understood and agreed that the obligation of CHL to
substitute for or to purchase, pursuant to Section 2.02(a), any Initial
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect
is not corrected or cured by CHL within 90 days from the date it was notified
of such defect, shall constitute the sole remedy respecting such defect
available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against any Seller.

            (b)   The Trustee agrees to execute and deliver on the Subsequent
Transfer Date to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) an Initial Certification substantially in the form annexed hereto as
Exhibit G-4 to the effect that, as to each Subsequent Mortgage Loan listed in
the Mortgage Loan Schedule (other than any Subsequent Mortgage Loan paid in
full or any Subsequent Mortgage Loan specifically identified in such
certification as not covered by such certification), the documents described
in Section 2.01(g)(i) and, in the case of each Subsequent Mortgage Loan that
is not a MERS Mortgage Loan, the documents described in Section 2.01(g)(iii),
with respect to such Subsequent Mortgage Loan are in its possession, and based
on its review and examination and only as to the foregoing documents, such
documents appear regular on their face and relate to such Subsequent Mortgage
Loan.

            The Trustee agrees to execute and deliver within 30 days after the
Subsequent Transfer Date to the Depositor, the Master Servicer and CHL (on
behalf of each Seller) an Interim Certification substantially in the form
annexed hereto as Exhibit G-2 to the effect that, as to each Subsequent
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Subsequent
Mortgage Loan paid in full or any Subsequent Mortgage Loan specifically
identified in such certification as not covered by such certification), all

face and relate to such Subsequent Mortgage Loan, and (ii) the information set
forth in items (i), (iv), (v), (vi), (viii), (ix) and (xvii) of the definition
of the "Mortgage Loan Schedule" accurately reflects information set forth in
the Mortgage File. On or before the thirtieth (30th) day after the Subsequent
Transfer Date (or if such thirtieth day is not a Business Day, the succeeding
Business Day), the Trustee shall deliver to the Depositor, the Master Servicer
and CHL (on behalf of each Seller) a Delay Delivery Certification with respect
to the Subsequent Mortgage Loans substantially in the form annexed hereto as
Exhibit G-3, with any applicable exceptions noted thereon, together with a
Subsequent Certification substantially in the form annexed hereto as Exhibit
G-4. The Trustee shall be under no duty or obligation to inspect, review or
examine such 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.

            Not later than 180 days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, CHL (on behalf of
each Seller) and to any Certificateholder that so requests a Final
Certification with respect to the Subsequent Mortgage Loans substantially in
the form annexed hereto as Exhibit H, with any applicable exceptions noted
thereon.

            In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee shall review each Mortgage File with
respect to the Subsequent Mortgage Loans to determine that such Mortgage File
contains the following documents:

                  (i)   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
      that show 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, if the original Mortgage
      Note has been lost or destroyed and not replaced, an original lost note,
      stating that the original Mortgage Note was lost or destroyed, together
      with a copy of the related Mortgage Note;

                  (ii)  in the case of each Subsequent Mortgage Loan that is
      not a MERS Mortgage Loan, the original recorded Mortgage, and in the
      case of each Subsequent Mortgage Loan that is a MERS Mortgage Loan, the
      original Mortgage, noting the presence of the MIN of the Subsequent
      Mortgage Loan and language indicating that the Subsequent Mortgage Loan
      is a MOM Loan if the Subsequent Mortgage Loan is a MOM Loan, with
      evidence of recording indicated thereon, or a copy of the Mortgage
      certified by the public recording office in which Mortgage has been

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

                  (vi)  the original or duplicate original lender's title
      policy or a printout of the electronic equivalent and all riders
      thereto.

            If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not
meet the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall
include such exceptions in such Final Certification (and the Trustee shall
state in such Final Certification whether any Mortgage File does not then

assignment so retained, with evidence of recording thereon, certified to be
true and complete by such recording office, shall be deemed to satisfy the

Mortgage Loan from the Trust Fund within 90 days from the date CHL was
notified of such defect in writing at the Purchase Price of such Subsequent
Mortgage Loan; provided that any such substitution pursuant to (A) above or
repurchase pursuant to (B) above shall not be effected

                                      76
<PAGE>

prior to the delivery to the Trustee of the Opinion of Counsel required by
Section 2.05 hereof and any substitution pursuant to (A) above shall not be
effected prior to the additional delivery to the Trustee of a Request for File
Release. No substitution will be made in any calendar month after the
Determination Date for such month. The Purchase Price for any such Subsequent
Mortgage Loan shall be deposited by CHL in the Certificate Account and, upon
receipt of such deposit and Request for File Release with respect thereto, the
Trustee shall release the related Mortgage File to CHL and shall execute and
deliver at CHL's request such instruments of transfer or assignment as CHL has
prepared, in each case without recourse, as shall be necessary to vest in CHL,
or a designee, the Trustee's interest in any Subsequent Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases a
Subsequent Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer
shall cause MERS to execute and deliver an assignment of the Mortgage in
recordable form to transfer the Mortgage from MERS to CHL and shall cause such
Mortgage to be removed from registration on the MERS(R) System in accordance
with MERS' rules and regulations.

            The Co-Trustee shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions set
forth herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of
such Seller from time to time.

            It is understood and agreed that the obligation of the Sellers to
substitute for or to purchase, pursuant to Section 2.02(b), any Subsequent
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect
is not corrected or cured by such Seller within 90 days from the date it was
notified of such defect, shall constitute the sole remedy respecting such
defect available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against the Sellers.

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

            (a)   The Master Servicer hereby represents and warrants to the

      other material agreement or instrument to which CHL is a party or by
      which it may be bound, or (C) constitute a material violation of any

                  (10)  No Mortgage Loan had a Loan-to-Value Ratio at
      origination in excess of 100.00%.

                  (11)  Each Mortgage Loan is secured by a valid and
      enforceable first lien on the related Mortgaged Property subject only to
      (1) the lien of non-delinquent current real property taxes and
      assessments, (2) covenants, conditions and restrictions, rights of way,
      easements and other matters of public record as of the date of recording
      of such Mortgage, such exceptions appearing of record being acceptable
      to mortgage lending institutions generally or specifically reflected in
      the appraisal made in connection with the origination of the related
      Mortgage Loan and (3) other matters to which like properties are
      commonly subject that do not materially interfere with the benefits of
      the security intended to be provided by such Mortgage.

                  (12)  Immediately prior to the assignment of each CHL
      Mortgage Loan to the Depositor, CHL had good title to, and was the sole
      owner of, such CHL Mortgage Loan free and clear of any pledge, lien,
      encumbrance or security interest and had full right and authority,
      subject to no interest or participation of, or agreement with, any other
      party, to sell and assign the same pursuant to this Agreement.

      any Mortgaged Property.

                  (14)  There is no valid offset, claim, defense or
      counterclaim to any Mortgage Note or Mortgage, including the obligation
      of the Mortgagor to pay the unpaid principal of or interest on such
      Mortgage Note.

                  (15)  There are no mechanics' liens or claims for work,
      labor or material affecting any Mortgaged Property that are or may be a
      lien prior to, or equal with, the lien of such Mortgage, except those
      that are insured against by the title insurance policy referred to in
      item (18) below.

                  (16)  As of the Closing Date in the case of the Initial
      Mortgage Loans and as of the related Subsequent Transfer Date in the
      case of the Subsequent Mortgage Loans, to the best of CHL's knowledge,
      each Mortgaged Property is free of material damage and is in good
      repair.

                  (17)  As of the Closing Date in the case of the Initial
      Mortgage Loans and as of the related Subsequent Transfer Date in the
      case of the Subsequent Mortgage Loans, neither CHL nor any prior holder
      of any Mortgage has modified the Mortgage in any material respect
      (except that a Mortgage Loan may have been modified by a written
      instrument that has been recorded or submitted for recordation, if
      necessary, to protect the interests of the Certificateholders and the
      original or a copy of which has been delivered to the Trustee);
      satisfied, cancelled or subordinated such Mortgage in whole or in part;
      released the related Mortgaged Property in whole or in part from the
      lien of such Mortgage; or executed any instrument of release,
      cancellation, modification (except as expressly permitted above) or
      satisfaction with respect thereto.

                  (18)  A lender's policy of title insurance together with a
      condominium endorsement and extended coverage endorsement, if
      applicable, in an amount at least equal to the Cut-off Date Principal
      Balance of each such Mortgage Loan or a commitment (binder) to issue the
      same was effective on the date of the origination of each Mortgage Loan,
      each such policy is valid and remains in full force and effect, and each
      such policy was issued by a title insurer qualified to do business in
      the jurisdiction where the Mortgaged Property is located and acceptable
      to Fannie Mae and Freddie Mac and is in a form acceptable to Fannie Mae
      and Freddie Mac, which policy insures the Sellers and successor owners
      of indebtedness secured by the insured Mortgage, as to the first
      priority lien, of the Mortgage subject to the exceptions set forth in
      paragraph (11) above; to the best of CHL's knowledge, no claims have
      been made under such mortgage title insurance policy and no prior holder
      of the related Mortgage, including any Seller, has done, by act or
      omission, anything that would impair the coverage of such mortgage title
      insurance policy.

                  (19)  No Initial Mortgage Loan was the subject of a
      Principal Prepayment in full between the Initial Cut-off Date and the
      Closing Date. No Subsequent Mortgage Loan was the subject of a Principal
      Prepayment in full between the Subsequent Cut-off Date and the
      Subsequent Transfer Date.

                  (20)  To the best of CHL's knowledge, all of the
      improvements that were included for the purpose of determining the
      Appraised Value of the Mortgaged Property lie wholly within the
      boundaries and building restriction lines of such property, and no
      improvements on adjoining properties encroach upon the Mortgaged
      Property.

                  (21)  To the best of CHL's knowledge, no improvement located
      on or being part of the Mortgaged Property is in violation of any
      applicable zoning law or regulation. To the best of CHL's knowledge, all
      inspections, licenses and certificates required to be made or issued
      with respect to all occupied portions of the Mortgaged Property and,
      with respect to the use and occupancy of the same, including but not
      limited to certificates of occupancy and fire underwriting certificates,
      have been made or obtained from the appropriate authorities, unless the
      lack thereof would not have a material adverse effect on the value of
      such Mortgaged Property, and the Mortgaged Property is lawfully occupied
      under applicable law.

                  (22)  The Mortgage Note and the related Mortgage are
      genuine, and each is the legal, valid and binding obligation of the
      maker thereof, enforceable in accordance with its terms and under
      applicable law, except that (a) the enforceability thereof may be
      limited by bankruptcy, insolvency, moratorium, receivership and other
      similar laws relating to creditors' rights generally and (b) the remedy
      of specific performance and injunctive and other forms of equitable
      relief may be subject to equitable defenses and to the discretion of the
      court before which any proceeding therefor may be brought. To the best
      of CHL's knowledge, all parties to the Mortgage Note and the Mortgage
      had legal capacity to execute the Mortgage Note and the Mortgage and
      each Mortgage Note and Mortgage have been duly and properly executed by
      such parties.

                                      82
<PAGE>

                  (23)  The proceeds of the Mortgage Loan have been fully
      disbursed, there is no requirement for future advances thereunder, and
      any and all requirements as to completion of any on-site or off-site
      improvements and as to disbursements of any escrow funds therefor have
      been complied with. All costs, fees and expenses incurred in making, or
      closing or recording the Mortgage Loan were paid.

                  (24)  The related Mortgage contains customary and
      enforceable provisions that render the rights and remedies of the holder
      thereof adequate for the realization against the Mortgaged Property of
      the benefits of the security, including, (i) in the case of a Mortgage
      designated as a deed of trust, by trustee's sale, and (ii) otherwise by
      judicial foreclosure.

                  (25)  With respect to each Mortgage constituting a deed of
      trust, a trustee, duly qualified under applicable law to serve as such,
      has been properly designated and currently so serves and is named in
      such Mortgage, and no fees or expenses are or will become payable by the
      Certificateholders to the trustee under the deed of trust, except in
      connection with a trustee's sale after default by the Mortgagor.

                  (26)  Each Mortgage Note and each Mortgage is acceptable in
      form to Fannie Mae and Freddie Mac.

                  (27)  There exist no deficiencies with respect to escrow
      deposits and payments, if such are required, for which customary
      arrangements for repayment thereof have not been made, and no escrow
      deposits or payments of other charges or payments due the Sellers have
      been capitalized under the Mortgage or the related Mortgage Note.

                  (28)  The origination, underwriting, servicing and
      collection practices with respect to each Mortgage Loan have been in all
      respects legal, proper, prudent and customary in the mortgage lending
      and servicing business, as conducted by prudent lending institutions
      which service mortgage loans of the same type in the jurisdiction in
      which the Mortgaged Property is located.

                  (29)  There is no pledged account or other security other
      than real estate securing the Mortgagor's obligations.

                  (30)  No Mortgage Loan has a shared appreciation feature, or
      other contingent interest feature.

                  (31)  Each Mortgage Loan contains a customary "due on sale"
      clause.

                  (32)  No less than approximately the percentage specified in
      the Collateral Schedule of the Initial Mortgage Loans in Loan Group 1,
      Loan Group 2, Loan Group 3 and Loan Group 4 are secured by single family
      detached dwellings. No more than approximately the percentage specified
      in the Collateral Schedule of the Initial Mortgage Loans in Loan Group
      1, Loan Group 2, Loan Group 3 and Loan Group 4 are secured by two- to
      four-family dwellings. No more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4 are secured by
      low-rise condominium units.

                                      83
<PAGE>

      No more than approximately the percentage specified in the Collateral
      Schedule of the Initial Mortgage Loans in Loan Group 1, Loan Group 2,
      Loan Group 3 and Loan Group 4 are secured by high-rise condominium
      units. No more than approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group 1, Loan
      Group 2, Loan Group 3 and Loan Group 4 are secured by manufactured
      housing. No more than approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group 1, Loan
      Group 2, Loan Group 3 and Loan Group 4 are secured by PUDs.

                  (33)  Each Initial Mortgage Loan in Loan Group 1, Loan Group
      2, Loan Group 3 and Loan Group 4 was originated on or after the date
      specified in the Collateral Schedule.

                  (34)  Each Initial Mortgage Loan that is an Adjustable Rate
      Mortgage Loan, other than a Two-Year Hybrid Mortgage Loan or a
      Three-Year Hybrid Mortgage Loan, had an initial Adjustment Date no later
      than the applicable date specified on the Collateral Schedule; each
      Initial Mortgage Loan that is a Two-Year Hybrid Mortgage Loan had an
      initial Adjustment Date no later than the applicable date specified on
      the Collateral Schedule; and each Initial Mortgage Loan that is a
      Three-Year Hybrid Mortgage Loan had an initial Adjustment Date no later
      than the applicable date specified on the Collateral Schedule.

                  (35)  Approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group 1, Loan
      Group 2, Loan Group 3 and Loan Group 4 provide for a prepayment penalty.

                  (36)  On the basis of representations made by the Mortgagors
      in their loan applications, no more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4, respectively,
      are secured by investor properties, and no less than approximately the
      percentage specified in the Collateral Schedule of the Initial Mortgage
      Loans in Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4
      respectively, are secured by owner-occupied Mortgaged Properties that
      are primary residences.

                  (37)  At the Cut-off Date, the improvements upon each
      Mortgaged Property are covered by a valid and existing hazard insurance
      policy with a generally acceptable carrier that provides for fire and
      extended coverage and coverage for such other hazards as are customary
      in the area where the Mortgaged Property is located 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 (a) the
      outstanding principal balance of the Mortgage Loan and (b) 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. If the
      Mortgaged Property is a condominium unit, it is included under the
      coverage afforded by a blanket policy for the condominium unit. All such
      individual insurance policies and all flood policies referred to in item
      (38) below contain a standard mortgagee clause naming the applicable
      Seller or the original mortgagee, and its successors in interest, as
      mortgagee, and the applicable Seller has received no notice that

                                      84
<PAGE>

      any premiums due and payable thereon have not been paid; the Mortgage
      obligates the Mortgagor thereunder to maintain all such insurance,
      including flood insurance, at the Mortgagor's cost and expense, and upon
      the Mortgagor's failure to do so, authorizes the holder of the Mortgage
      to obtain and maintain such insurance at the Mortgagor's cost and
      expense and to seek reimbursement therefor from the Mortgagor.

                  (38)  If the Mortgaged Property is in an area identified in
      the Federal Register by the Federal Emergency Management Agency as
      having special flood hazards, a flood insurance policy in a form meeting
      the requirements of the current guidelines of the Flood Insurance
      Administration is in effect with respect to such Mortgaged Property with
      a generally acceptable carrier in an amount representing coverage not
      less than the least of (A) the original outstanding principal balance of
      the Mortgage Loan, (B) the minimum amount required to compensate for
      damage or loss on a replacement cost basis, or (C) the maximum amount of
      insurance that is available under the Flood Disaster Protection Act of
      1973, as amended.

                  (39)  To the best of CHL's knowledge, there is no proceeding
      occurring, pending or threatened for the total or partial condemnation
      of the Mortgaged Property.

                  (40)  There is no material monetary default existing under
      any Mortgage or the related Mortgage Note and, to the best of CHL's
      knowledge, there is no material event that, with the passage of time or
      with notice and the expiration of any grace or cure period, would
      constitute a default, breach, violation or event of acceleration under
      the Mortgage or the related Mortgage Note; and no Seller has waived any
      default, breach, violation or event of acceleration.

                  (41)  Each Mortgaged Property is improved by a one- to
      four-family residential dwelling, including condominium units and
      dwelling units in PUDs. To the best of CHL's knowledge, no improvement
      to a Mortgaged Property includes a cooperative or a mobile home or
      constitutes other than real property under state law.

                  (42)  Each Mortgage Loan is being serviced by the Master
      Servicer.

                  (43)  Any future advances made prior to the Cut-off Date
      have been consolidated with the outstanding principal amount secured by
      the Mortgage, and the secured principal amount, as consolidated, bears a
      single interest rate and single repayment term reflected on the Mortgage
      Loan Schedule. The consolidated principal amount does not exceed the
      original principal amount of the Mortgage Loan. The Mortgage Note does
      not permit or obligate the Master Servicer to make future advances to
      the Mortgagor at the option of the Mortgagor.

                  (44)  All taxes, governmental assessments, insurance
      premiums, water, sewer and municipal charges, leasehold payments or
      ground rents that previously became due and owing have been paid, or an
      escrow of funds has been established in an amount sufficient to pay for
      every such item that remains unpaid and that has been assessed, but is
      not yet due and payable. Except for (A) payments in the nature of escrow
      payments, and (B) interest accruing from the date of the Mortgage Note
      or date of disbursement of

                                      85
<PAGE>

      the Mortgage proceeds, whichever is later, to the day that precedes by
      one month the Due Date of the first installment of principal and
      interest, including without limitation, taxes and insurance payments,
      the Master Servicer has not advanced funds, or induced, solicited or
      knowingly received any advance of funds by a party other than the
      Mortgagor, directly or indirectly, for the payment of any amount
      required by the Mortgage.

                  (45)  The Mortgage Loans originated by CHL were underwritten

      guidelines for credit blemished quality mortgage loans or, with respect

      guidelines generally used by originators of credit blemished quality
      mortgage loans.

                  (46)  Prior to the approval of the Mortgage Loan
      application, an appraisal of the related Mortgaged Property was obtained
      from a qualified appraiser, duly appointed by the originator, who had no
      interest, direct or indirect, in the Mortgaged Property or in any loan
      made on the security thereof, and whose compensation is not affected by
      the approval or disapproval of the Mortgage Loan; such appraisal is in a
      form acceptable to Fannie Mae and Freddie Mac.

                  (47)  None of the Mortgage Loans is a graduated payment
      mortgage loan or a growing equity mortgage loan, and no Mortgage Loan is
      subject to a buydown or similar arrangement.

                  (48)  The Mortgage Rates borne by the Initial Mortgage Loans
      in Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4 as of the
      Cut-off Date ranged between the approximate per annum percentages
      specified on the Collateral Schedule and the weighted average Mortgage
      Rate as of the Cut-off Date was approximately the per annum rate
      specified on the Collateral Schedule.

                  (49)  The Mortgage Loans were selected from among the
      outstanding one- to four-family mortgage loans in the applicable
      Seller's portfolio at the Closing Date as to which the representations
      and warranties made as to the Mortgage Loans set forth in this Section
      2.03(b) and Section 2.03(c) can be made. No selection was made in a
      manner that would adversely affect the interests of Certificateholders.

                  (50)  The Gross Margins on the Initial Mortgage Loans in :
      Loan Group 1, Loan Group 2, Loan Group 3 and Loan Group 4 range between
      the approximate percentages specified on the Collateral Schedule, and
      the weighted average Gross Margin was approximately the percentage
      specified in the Collateral Schedule.

                  (51)  Each of the Initial Mortgage Loans in the Mortgage
      Pool has a Due Date on or before the date specified in the Collateral
      Schedule.

                  (53)  There is no obligation on the part of any Seller under
      the terms of the Mortgage or related Mortgage Note to make payments in
      addition to those made by the Mortgagor.

                  (54)  Any leasehold estate securing a Mortgage Loan has a
      term of not less than five years in excess of the term of the related
      Mortgage Loan.

                  (55)  Each Mortgage Loan represents a "qualified mortgage"
      within the meaning of Section 860(a)(3) of the Code (but without regard
      to the rule in Treasury Regulation ss. 1.860G-2(f)(2) that treats a
      defective obligation as a qualified mortgage, or any substantially
      similar successor provision) and applicable Treasury regulations
      promulgated thereunder.

                  (56)  No Mortgage Loan was either a "consumer credit
      contract" or a "purchase money loan" as such terms are defined in 16
      C.F.R. ss. 433 nor is any Mortgage Loan a "mortgage" as defined in 15
      U.S.C. ss. 1602(aa).

                  (57)  To the extent required under applicable law, each
      originator and subsequent mortgagee or servicer of the Mortgage Loan
      complied with all licensing requirements and was authorized to transact
      and do business in the jurisdiction in which the related Mortgaged
      Property is located at all times when it held or serviced the Mortgage
      Loan. Any and all requirements of any federal, state or local laws or
      regulations, including, without limitation, usury, truth-in-lending,
      real estate settlement procedures, consumer credit protection,
      anti-predatory lending, fair credit reporting, unfair collection
      practice, equal credit opportunity, fair housing and disclosure laws and
      regulations, applicable to the solicitation, origination, collection and
      servicing of such Mortgage Loan have been complied with in all material
      respects; and any obligations of the holder of the Mortgage Note,
      Mortgage and other loan documents have been complied with in all
      material respects; servicing of each Mortgage Loan has been in
      accordance with prudent mortgage servicing standards, any applicable
      laws, rules and regulations and in accordance with the terms of the
      Mortgage Notes, Mortgage and other loan documents, whether such
      origination and servicing was done by the applicable Seller, its
      affiliates, or any third party which originated the Mortgage Loan on
      behalf of, or sold the Mortgage Loan to, any of them, or any servicing
      agent of any of the foregoing.

                  (58)  The methodology used in underwriting the extension of
      credit for the Mortgage Loan employs objective mathematical principles
      which relate the borrower's income, assets and liabilities to the
      proposed payment and such underwriting methodology does not rely on the
      extent of the borrower's equity in the collateral as the principal
      determining factor in approving such credit extension. Such underwriting
      methodology confirmed that at the time of origination
      (application/approval) the borrower had a reasonable ability to make
      timely payments on the Mortgage Loan.

                  (59)  No borrower was required to purchase any credit life,
      disability, accident or health insurance product as a condition of
      obtaining the extension of credit.

      accident or health insurance policy in connection with the origination
      of the Mortgage Loan;

                  (60)  If the Mortgage Loan provides that the interest rate
      on the principal balance of the related Mortgage Loan may be adjusted,
      all of the terms of the related Mortgage pertaining to interest rate
      adjustments, payment adjustments and adjustments of the outstanding
      principal balance have been made in accordance with the terms of the
      related Mortgage Note and applicable law and are enforceable and such
      adjustments will not affect the priority of the Mortgage lien;

                  (61)  The Mortgaged Property complies with all applicable
      laws, rules and regulations relating to environmental matters, including
      but not limited to those relating to radon, asbestos and lead paint and
      no Seller nor, to the best of CHL's knowledge, the Mortgagor, has
      received any notice of any violation or potential violation of such law;

                  (62)  There is no action, suit or proceeding pending, or to
      the best of CHL's knowledge, threatened or likely to be asserted with
      respect to the Mortgage Loan against or affecting any Seller before or
      by any court, administrative agency, arbitrator or governmental body;

                  (63)  No action, inaction, or event has occurred and no
      state of fact exists or has existed that has resulted or will result in
      the exclusion from, denial of, or defense to coverage under any
      applicable hazard insurance policy, irrespective of the cause of such
      failure of coverage. In connection with the placement of any such
      insurance, no commission, fee, or other compensation has been or will be
      received by CHL or any designee of CHL or any corporation in which CHL
      or any officer, director, or employee had a financial interest at the
      time of placement of such insurance;

      on CHL's behalf, and CHL has no knowledge, of any relief requested or
      allowed to a Mortgagor under the Relief Act;

                  (66)  Each Mortgage Loan was originated by a savings and
      loan association, savings bank, commercial bank, credit union, insurance
      company, or mortgage banking company which is supervised and examined by
      a federal or state authority, or by a mortgagee approved by the
      Secretary of Housing and Urban Development pursuant to Sections 2.03 and
      2.11 of the National Housing Act;

                  (67)  Each Mortgage Loan was (A) originated no earlier than

      applicable Seller in accordance with the applicable Seller's
      underwriting guidelines in effect at the time the loan was underwritten
      or reunderwritten, as applicable;

<PAGE>

                  (68)  Each Mortgage Loan, at the time it was originated and
      as of the Closing Date or the related Subsequent Transfer Date, as
      applicable, complied in all material respects with applicable local,

      (2004);

                  (72)  There is no Mortgage Loan in the Trust Fund that was

                  (73)  No Mortgage Loan in the Trust Fund is a High Cost Loan

      the contract was originated (determined pursuant to the REMIC

            clause that requires the borrower to submit to arbitration to
            resolve any dispute arising out of or relating in any way to the
            mortgage loan transaction), CHL will (i) notify the related
            borrower in writing within 60 days after the issuance of the

            credit history and debt-to-income ratios for a lower-cost credit
            product then offered by such Mortgage Loan's originator or any

            credit for each Mortgage Loan in Loan Group 4 employs objective

            modified to reduce the prepayment period to no more than three
            years from the date of the note and the borrower was notified in

            from any Mortgage Loan in Loan Group 4 were used to purchase

            4 in an original principal amount of less than $60,000 which would
            have resulted in an unprofitable origination, no borrower was
            charged "points and fees" (whether or not financed) in an amount
            greater than 5% of the principal amount of such loan, such 5%

                  (4)   No litigation is pending or, to the best of Park
      Monaco's knowledge, threatened, against Park Monaco that would
      materially and adversely affect the execution, delivery or
      enforceability of this Agreement or any Subsequent Transfer Agreement or
      the ability of Park Monaco to sell the Park Monaco Mortgage Loans or to
      perform any of its other obligations under this Agreement or any
      Subsequent Transfer Agreement in accordance with the terms hereof or
      thereof.

                  (5)   No consent, approval, authorization or order of any
      court or governmental agency or body is required for the execution,
      delivery and performance by Park Monaco of, or compliance by Park Monaco
      with, this Agreement or any Subsequent Transfer Agreement or the
      consummation of the transactions contemplated hereby, or if any such
      consent, approval, authorization or order is required, Park Monaco has
      obtained the same.

                  (6)   Park Monaco will treat the transfer of the Park Monaco

      Loans for all tax, accounting and regulatory purposes.

      Agreement.

            (d)   Park Sienna hereby represents and warrants to the Depositor
and the Trustee as follows, as of the Cut-off Date:

                                      94

                  (3)   The execution and delivery of this Agreement and each

                  (4)   No litigation is pending or, to the best of Park
      Sienna's knowledge, threatened, against Park Sienna that would

<PAGE>

      delivery or enforceability of this Agreement or any Subsequent Transfer
      Agreement or the ability of Park Sienna to sell the Park Sienna Mortgage
      Loans or to perform any of its other obligations under this Agreement or
      any Subsequent Transfer Agreement in accordance with the terms hereof or
      thereof.

                  (5)   No consent, approval, authorization or order of any
      court or governmental agency or body is required for the execution,
      delivery and performance by Park Sienna of, or compliance by Park Sienna

      consent, approval, authorization or order is required, Park Sienna has
      obtained the same.

                  (6)   Park Sienna will treat the transfer of the Park Sienna
      Mortgage Loans to the Depositor as a sale of the Park Sienna Mortgage
      Loans for all tax, accounting and regulatory purposes.

                  (7)   Immediately prior to the assignment of each Park
      Sienna Mortgage Loan to the Depositor, Park Sienna had good title to,
      and was the sole owner of, such the Park Sienna Mortgage Loan free and
      clear of any pledge, lien, encumbrance or security interest and had full
      right and authority, subject to no interest or participation of, or
      agreement with, any other party, to sell and assign the same pursuant to
      this Agreement.

            (e)   Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) through (d) that
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, the party discovering such breach shall give prompt notice
thereof to the other parties and the NIM Insurer. Each of the Master Servicer
and the Sellers (each, a "Representing Party") hereby covenants with respect
to the representations and warranties set forth in Sections 2.03(a) through
(d) that within 90 days of the earlier of the discovery by such Representing
Party or receipt of written notice by such Representing Party from any party
of a breach of any representation or warranty set forth herein made that
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan or the Class AF-5B Insurer, 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 Replacement 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 that (a) any such substitution pursuant to
(i) above or repurchase pursuant to (ii) above shall not be effected prior to
the delivery to the Trustee, of the Opinion of Counsel required by Section
2.05 hereof, (b) any such substitution pursuant to (i) above shall not be
effected prior to the additional delivery to the Trustee of a Request for File
Release and (c) any such substitution pursuant to (i) above shall include a
payment by the applicable Representing Party of any amount as calculated under
item (iii) of the definition of "Purchase Price". Any Representing Party
liable for a breach under this Section 2.03 shall promptly reimburse the
Master Servicer or the Trustee for any expenses reasonably incurred by the
Master Servicer or the Trustee in respect of enforcing the remedies for such
breach. To enable the Master Servicer to amend the Mortgage Loan Schedule, any
Representing Party liable for a breach under this Section 2.03 shall, unless
it cures such breach in a timely fashion pursuant to this Section 2.03,
promptly notify the Master Servicer whether such Representing Party intends
either to repurchase, or to substitute for, the

                                      96
<PAGE>

Mortgage Loan affected by such breach. With respect to the representations and
warranties described in this Section that are made to the best of the
Representing Party's knowledge, if it is discovered by any of the Depositor,
the Master Servicer, the Sellers 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, notwithstanding the
Representing Party'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 Section 2.03(a)(8), (b)(72), (b)(75), (b)(76) or (b)(77) shall be
deemed to materially and adversely affect the Certificateholders.

            With respect to any Replacement Mortgage Loan or Loans, the
applicable Seller delivering such Replacement Mortgage Loan shall deliver to
the Trustee for the benefit of the Certificateholders the related Mortgage
Note, Mortgage and 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 will be
made in any calendar month after the Determination Date for such month.
Scheduled Payments due with respect to Replacement Mortgage Loans in the Due
Period related to the Distribution Date on which such proceeds are to be
distributed shall not be part of the Trust Fund and will be retained by the
applicable Seller delivering such Replacement Mortgage Loan on such
Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for the related Due Period and thereafter the applicable 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 Replacement Mortgage Loan or Loans
and the Master Servicer shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Replacement Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the
applicable Seller delivering such Replacement Mortgage Loan shall be deemed to
have made with respect to such Replacement Mortgage Loan or Loans, as of the
date of substitution, the representations and warranties set forth in Section
2.03(b), (c) or (d) 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 Co-Trustee shall release to the Representing
Party the Mortgage File relating to such Deleted Mortgage Loan and held for
the benefit of the Certificateholders and shall execute and deliver at the
Master Servicer's direction such instruments of transfer or assignment as have
been prepared by the Master Servicer, in each case without recourse, as shall
be necessary to vest in the applicable Seller, or its respective designee,
title to the Trustee's interest in any Deleted Mortgage Loan substituted for
pursuant to this Section 2.03.

            For any month in which any Seller substitutes one or more
Replacement 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 such Replacement Mortgage Loans as of the date of substitution
is less than the Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) of all such
Deleted Mortgage Loans. An amount equal to the aggregate of the deficiencies
described in the preceding sentence (such amount, the "Substitution Adjustment
Amount") shall be forwarded by the applicable Seller to the Master Servicer
and deposited by the Master Servicer into the Certificate Account not later
than the Determination Date for the Distribution Date relating to the

                                      97
<PAGE>

Prepayment Period 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 the Determination Date for the Distribution Date
in the month following the month during which such Seller became obligated 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, if
any, and the receipt of a Request for File Release, the Co-Trustee shall
release the related Mortgage File held for the benefit of the
Certificateholders to such Seller, and the Trustee shall execute and deliver
at such Person's direction the related instruments of transfer or assignment
prepared by such Seller, in each case without recourse, as shall be necessary
to transfer title from the Trustee for the benefit of the Certificateholders
and transfer the Trustee's interest to such Seller to any Mortgage Loan
purchased pursuant to this Section 2.03. It is understood and agreed that the
obligation under this Agreement of the Sellers to cure, repurchase or replace
any Mortgage Loan as to which a breach has occurred and is continuing shall
constitute the sole remedy against the Sellers respecting such breach
available to Certificateholders, the Depositor or the Trustee.

            (f)   The representations and warranties set forth in this Section
2.03 shall survive delivery of the respective Mortgage Files to the Co-Trustee
for the benefit of the Certificateholders with respect to each Mortgage Loan.

            Section 2.04      Representations and Warranties of the Depositor.

            The Depositor hereby represents and warrants to the Master
Servicer and the Trustee as follows, as of the date hereof and as of each
Subsequent Transfer Date:

                  (1)   The Depositor is duly organized and is validly
      existing as a corporation in good standing under the laws of the State
      of Delaware and has full power and authority (corporate and other)
      necessary to own or hold its properties and to conduct its business as
      now conducted by it and to enter into and perform its obligations under
      this Agreement and each Subsequent Transfer Agreement.

                  (2)   The Depositor has the full corporate power and
      authority to execute, deliver and perform, and to enter into and
      consummate the transactions contemplated by, this Agreement and each
      Subsequent Transfer Agreement and has duly authorized, by all necessary
      corporate action on its part, the execution, delivery and performance of
      this Agreement and each Subsequent Transfer Agreement; and this
      Agreement and each Subsequent Transfer Agreement, assuming the due
      authorization, execution and delivery hereof by the other parties
      hereto, constitutes a legal, valid and binding obligation of the
      Depositor, enforceable against the Depositor in accordance with its
      terms, subject, as to enforceability, to (i) bankruptcy, insolvency,
      reorganization, moratorium and other similar laws affecting creditors'
      rights generally and (ii) general principles of equity, regardless of
      whether enforcement is sought in a proceeding in equity or at law.

                                      98
<PAGE>

                  (3)   The execution and delivery of this Agreement and each
      Subsequent Transfer Agreement by the Depositor, the consummation of the
      transactions contemplated by this Agreement, and the fulfillment of or
      compliance with the terms hereof are in the ordinary course of business
      of the Depositor and will not (A) result in a material breach of any
      term or provision of the charter or by-laws of the Depositor or (B)
      materially conflict with, result in a material breach, violation or
      acceleration of, or result in a material default under, the terms of any
      other material agreement or instrument to which the Depositor is a party
      or by which it may be bound or (C) constitute a material violation of
      any statute, order or regulation applicable to the Depositor of any
      court, regulatory body, administrative agency or governmental body
      having jurisdiction over the Depositor; and the Depositor is not in
      breach or violation of any material indenture or other material
      agreement or instrument, or in violation of any statute, order or
      regulation of any court, regulatory body, administrative agency or
      governmental body having jurisdiction over it which breach or violation
      may materially impair the Depositor's ability to perform or meet any of
      its obligations under this Agreement.

                  (4)   No litigation is pending, or, to the best of the
      Depositor's knowledge, threatened, against the Depositor that would
      materially and adversely affect the execution, delivery or
      enforceability of this Agreement or any Subsequent Transfer Agreement or
      the ability of the Depositor to perform its obligations under this
      Agreement or any Subsequent Transfer Agreement in accordance with the
      terms hereof or thereof.

                  (5)   No consent, approval, authorization or order of any
      court or governmental agency or body is required for the execution,
      delivery and performance by the Depositor of, or compliance by the
      Depositor with, this Agreement or any Subsequent Transfer Agreement or
      the consummation of the transactions contemplated hereby, or if any such
      consent, approval, authorization or order is required, the Depositor has
      obtained the same.

            The Depositor hereby represents and warrants to the Trustee with
respect each Mortgage Loan, as of the Closing Date or the related Subsequent
Transfer Date, as applicable, following the transfer of such Mortgage Loan to
it by the Sellers, the Depositor had good title to the Initial Mortgage Loans
or related Subsequent Mortgage Loans, as applicable, and the related Mortgage
Notes were subject to no offsets, claims, defenses or counterclaims.

            It is understood and agreed that the representations and
warranties set forth in the two immediately preceding paragraphs shall survive
delivery of the Mortgage Files to the Co-Trustee. Upon discovery by the
Depositor or the Trustee, with respect to any Mortgage Loan of a breach of any
of the foregoing representations and warranties set forth in the immediately
preceding paragraph (referred to herein as a "breach"), which breach
materially and adversely affects the interest of the Certificateholders, with
respect to any Mortgage Loan the party discovering such breach shall give
prompt written notice to the others and to each Rating Agency and the NIM
Insurer. The Depositor hereby covenants with respect to the representations
and warranties made by it in this Section 2.04 that within 90 days of the
earlier of the discovery it or receipt of written notice by it from any party
of a breach of any representation or warranty set forth herein made that
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, it shall cure such breach in all material respects and, if
such breach is not so

                                      99
<PAGE>

cured, shall repurchase or replace the affected Mortgage Loan or Loans in
accordance with the procedure set forth in Section 2.03(e).

            Section 2.05      Delivery  of Opinion  of  Counsel in  Connection
                              with Substitutions and Repurchases.

            (a)   Notwithstanding any contrary provision of this Agreement,
with respect to any Mortgage Loan that is not in default or as to which
default is not imminent, no repurchase or substitution pursuant to Sections
2.02, 2.03 or 2.04 shall be made unless the Representing Party making such
repurchase or substitution delivers to the Trustee an Opinion of Counsel
(which such Representing Party shall use reasonable efforts to obtain)
addressed to the Trustee to the effect that such repurchase or substitution
would not (i) result in the imposition of the tax on "prohibited transactions"
of the Trust Fund or contributions after the Closing Date, as defined in
sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause
any REMIC formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding. Any Mortgage Loan as to which repurchase or
substitution was delayed pursuant to this paragraph shall be repurchased or
the substitution therefor shall occur (subject to compliance with Sections
2.02, 2.03 or 2.04) upon the earlier of (a) the occurrence of a default or
imminent default with respect to such loan and (b) receipt by the Trustee of
an Opinion of Counsel to the effect that such repurchase or substitution, as
applicable, will not result in the events described in clause (i) or clause
(ii) of the preceding sentence.

            (b)   Upon discovery by the Depositor, any 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
Business Days of discovery) give written notice thereof to the other parties
and the NIM Insurer. In connection therewith, the Trustee shall require CHL,
at CHL's option, to either (i) substitute, if the conditions in Section
2.03(e) with respect to substitutions are satisfied, a Replacement 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 contained in Section
2.03. The Trustee shall reconvey to CHL the Mortgage Loan to be released
pursuant hereto 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      Authentication 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,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations evidencing 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
best of its ability, to the end that the interests of the Holders of the
Certificates may be adequately and effectively protected.

            Section 2.07      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

            (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 the 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 customary
and usual standards of practice of prudent mortgage loan lenders in the
respective states in which the Mortgaged Properties are located, including
taking all required and appropriate actions under each Required Insurance
Policy. 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 hereof, subject to the terms hereof
(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, other Liquidation
Proceeds and Subsequent Recoveries, and (iv) subject to Section 3.12(b), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that the Master Servicer shall
take no action that is inconsistent with or prejudices the interests of the
Trustee or the Certificateholders in any Mortgage Loan or the rights and
interests of the Depositor and the Trustee under this Agreement. The Master
Servicer shall represent and protect the interest of the Trustee in the same
manner as it currently protects its own interest 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 term of
any Mortgage Loan which would (i) cause any REMIC formed hereunder to fail to
qualify as a REMIC or (ii) result in the imposition of any tax under section
860(a) or 860(d) of the Code, but in any case the Master Servicer shall not
act in any manner that is a lesser standard than that provided in the first
sentence of this Section 3.01. 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

                                      101
<PAGE>

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 any or all of them as are necessary or appropriate to enable the Master
Servicer to service and administer the Mortgage Loans. 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.

            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. All 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 Balance under the related Mortgage Loans, notwithstanding
that the terms of such Mortgage Loans so permit.

            The Master Servicer shall deliver a list of Servicing Officers to
the Trustee by the Closing Date.

            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 the Certificateholders, claims to the insurer under any
primary insurance policies and, in this regard, to take any reasonable action
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.

            In the event that a shortfall in any collection on or liability
with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Scheduled Payments or Stated Principal Balances
that were made by the Master Servicer in a manner not consistent with the
terms of the related Mortgage Note and this Agreement, the Master Servicer,
upon discovery or receipt of notice thereof, immediately shall deliver to the
Trustee for deposit in the Distribution Account from its own funds the amount
of any such shortfall and shall indemnify and hold harmless the Trust Fund,
the Trustee, the Depositor and any successor master servicer in respect of any
such liability. Such indemnities shall survive the termination or discharge of
this Agreement. Notwithstanding the foregoing, this Section 3.01 shall not
limit the ability of the Master Servicer to seek recovery of any such amounts
from the related Mortgagor under the terms of the related Mortgage Note, as
permitted by law and shall not be an expense of the Trust.

            Section 3.02      Subservicing;  Enforcement of the Obligations of
                              Master Servicer.

            (a)   The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided that (i)
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 hereunder, (ii) that
such subservicing agreements would not result in a withdrawal or a downgrading
by any Rating Agency of the ratings on any Class of Certificates (without
regard to the Class AF-5B Policy in the case of the Class AF-5B Certificates),
as evidenced by a letter to that effect delivered by each Rating Agency to the
Depositor and the NIM Insurer and (iii) the NIM Insurer shall have consented
to such subservicing agreements (which consent shall not be unreasonably
withheld) with Subservicers, for the servicing and administration of the
Mortgage Loans. The Master Servicer shall deliver to the Trustee copies of all
Sub-Servicing Agreements, and any amendments or modifications thereof,
promptly upon the Master Servicer's execution and delivery of such
instruments. The Master Servicer, with the written consent of the NIM Insurer
(which consent shall not be unreasonably withheld), shall be entitled to
terminate any Subservicing Agreement and the rights and obligations of any
Subservicer pursuant to any Subservicing Agreement in accordance with the
terms and conditions of such Subservicing Agreement. Notwithstanding the
provisions of any subservicing agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Master Servicer
or a subservicer or reference to actions taken through a Master Servicer 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. Every subservicing agreement entered into by the Master Servicer shall
contain a provision giving the successor Master Servicer the option to
terminate such agreement without cost in the event a successor Master Servicer
is appointed. 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 Sellers, the
                              Certificateholders, the NIM Insurer, the Class
                              AF-5B Insurer and the Trustee in Respect of the
                              Master Servicer.

            None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer, the Class AF-5B Insurer or the Depositor shall have any
responsibility or liability for any action or failure to act by the Master
Servicer, and none of them is obligated to supervise the performance of the
Master Servicer hereunder or otherwise. The Master Servicer shall afford (and
any

                                      103
<PAGE>

Subservicing Agreement shall provide that each Subservicer shall afford) the
Depositor, the NIM Insurer, the Class AF-5B Insurer and the Trustee, upon
reasonable notice, during normal business hours, access to all records
maintained by the Master Servicer (and any such Subservicer) in respect of the
Master Servicer's rights and obligations hereunder and access to officers of
the Master Servicer (and those of any such Subservicer) responsible for such
obligations. Upon request, the Master Servicer shall furnish to the Depositor,
the NIM Insurer, the Class AF-5B Insurer and the Trustee its (and any such
Subservicer's) most recent financial statements and such other information
relating to the Master Servicer's capacity to perform its obligations under
this Agreement that it possesses. To the extent such information is not
otherwise available to the public, the Depositor, the Class AF-5B Insurer, the
NIM Insurer and the Trustee shall not disseminate any information obtained
pursuant to the preceding two sentences without the Masters Servicer's (or any
such Subservicer's) written consent, except as required pursuant to this
Agreement or to the extent that it is necessary to do so (i) in working with
legal counsel, auditors, taxing authorities or other governmental agencies,
rating agencies or reinsurers or (ii) pursuant to any law, rule, regulation,
order, judgment, writ, injunction or decree of any court or governmental
authority having jurisdiction over the Depositor, the Trustee, the Class AF-5B
Insurer, the NIM Insurer or the Trust Fund, and in either case, the Depositor,
the Class AF-5B Insurer, the NIM Insurer or the Trustee, as the case may be,
shall use its reasonable best efforts to assure the confidentiality of any
such disseminated non-public information. 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
or exercise the rights of the Master Servicer under this Agreement; provided
by virtue of such performance by the Depositor of its designee. The Depositor
shall not have any responsibility or liability for any action or failure to
act by the Master Servicer and is not 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 hereunder (including by reason of an Event of
Default), the Trustee or its designee shall thereupon assume all of the rights
and obligations of the Master Servicer hereunder arising thereafter (except
that the Trustee shall not be (i) liable for losses of the Master Servicer
pursuant to Section 3.10 hereof or any acts or omissions of the predecessor
Master Servicer hereunder, (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 hereunder, including pursuant to Section 2.02
or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant
to Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.03 or the first paragraph of
Section 6.02 hereof). If the Master Servicer shall for any reason no longer be
the Master Servicer (including by reason of any Event of Default), the Trustee
(or any other successor servicer) may, at its option, succeed to any rights
and obligations of the Master Servicer under any subservicing agreement in
accordance with the terms thereof; provided that the Trustee (or any other
successor servicer) shall not incur any liability or have any obligations in
its capacity as servicer under a subservicing agreement arising prior to the
date of such succession unless it expressly elects to succeed to the rights
and obligations of the Master Servicer thereunder; and the Master Servicer
shall not thereby be

                                      104
<PAGE>

relieved of any liability or obligations under the subservicing agreement
arising prior to the date of such succession.

            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 and the Mortgage Loans
then being serviced thereunder and an accounting of amounts collected held by
it and otherwise use its best efforts to effect the orderly and efficient
transfer of the subservicing agreement to the assuming party.

            Section 3.05      Collection of Mortgage Loan Payments;
                              Certificate Account; Distribution Account;
                              Pre-Funding Account; Seller Shortfall Interest
                              Requirement.

            (a)   The Master Servicer shall make reasonable efforts in
accordance with customary and usual standards of practice of prudent mortgage
lenders in the respective states in which the Mortgaged Properties are located
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 270 days. In the event of any such
arrangement, the Master Servicer shall make Advances on the related Mortgage
Loan 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 have been granted such waivers or extensions
exceeds 5% of the aggregate number of Initial Mortgage Loans and Subsequent
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 on a daily basis within two Business Days of receipt, except as
otherwise specifically provided herein, 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 hereunder:

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

                                      105
<PAGE>

                  (2)   all payments on account of interest on the Mortgage
      Loans (net of the related Servicing Fee and Prepayment Interest Excess
      permitted under Section 3.15 hereof to the extent not previously paid to
      or withheld by the Master Servicer);

                  (3)   all Insurance Proceeds;

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

                  (5)   all Compensating Interest;

                  (6)   any amount required to be deposited by the Master
      Servicer pursuant to Section 3.05(e) in connection with any losses on
      Permitted Investments;

                  (7)   any amounts required to be deposited by the Master
      Servicer pursuant to Section 3.10 hereof;

                  (8)   the Purchase Price and any Substitution Adjustment
      Amount;

                  (9)   all Advances made by the Master Servicer or the
      Trustee pursuant to Section 4.01 hereof;

                  (10)  all Prepayment Charges and Master Servicer Prepayment
      Charge Payment Amounts; and

                  (11)  any other amounts required to be deposited hereunder.

            The foregoing requirements for remittance by the Master Servicer
into the Certificate Account 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 and not otherwise subject to
withdrawal pursuant to Section 3.08 hereof, it may at any time withdraw or
direct the institution maintaining the Certificate Account, to withdraw such
amount from the Certificate Account, any provision herein to the contrary
notwithstanding. Such withdrawal or direction may be accomplished by
delivering written notice thereof to the institution maintaining the
Certificate Account, that 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.

            No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in each of April 2005, May 2005 and June
2005, CHL shall remit to the Master Servicer, and the Master Servicer shall
deposit in the Certificate Account, the Seller Shortfall Interest Requirement
(if any) for such Master Servicer Advance Date.

                                      106
<PAGE>

            (c)   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 therein the following:

                  (1)   the aggregate amount remitted by the Master Servicer
      pursuant to the second paragraph of Section 3.08(a); and

                  (2)   any amount required to be deposited by the Master
      Servicer pursuant to Section 3.05(e) in connection with any losses on
      Permitted Investments.

            The foregoing requirements for remittance by the Master Servicer
and deposit by the Trustee into the Distribution Account shall be exclusive.
In the event that the Master Servicer shall remit any amount not required to
be remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding.
Such direction may be accomplished by delivering a written notice to the
Trustee that 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.

            (d)   The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Pre-Funding Account. On the Closing Date, CHL shall
remit the Pre-Funded Amount to the Trustee for deposit in the Pre-Funding
Account.

            On the Business Day before the Distribution Date following the end
of the Funding Period, the Trustee shall (i) withdraw the amount on deposit in
the Pre-Funding Account (net of investment income), (ii) promptly deposit such
amount in the Distribution Account, and (iii) distribute each amount to the
Certificates on the Distribution Date pursuant to Section 4.04.

            (e)   Each institution that maintains the Certificate Account, the
Distribution Account or the Pre-Funding Account shall invest the funds in each
such account, as directed by the Master Servicer, in Permitted Investments,
which shall mature not later than (x) in the case of the Certificate 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 Certificate Account, then such Permitted
Investment shall mature not later than the Business Day next preceding such
Distribution Account Deposit Date) and (y) in the case of the Distribution
Account and the Pre-Funding Account, 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 such Distribution Account or Pre-Funding Account, then such
Permitted Investment shall mature not later than such Distribution Date), 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. In the case of (i) the Certificate Account
and the Distribution Account, all income and gain net of any losses realized
from any such investment shall be for the benefit of

                                      107
<PAGE>

the Master Servicer as servicing compensation and shall be remitted to it
monthly as provided herein and (ii) the Pre-Funding Account, all income and
gain net of any losses realized from any such investment shall be for the
benefit of CHL and shall be remitted to CHL as provided herein. The amount of
any losses incurred in the Certificate Account or the Distribution Account in
respect of any such investments shall be deposited by the Master Servicer in
the Certificate Account or paid to the Trustee for deposit into the
Distribution Account out of the Master Servicer's own funds immediately as
realized. The amount of any losses incurred in the Pre-Funding Account in
respect of any such investments shall be paid by CHL to the Trustee for
deposit into the Pre-Funding Account out of CHL's own funds 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
Certificate Account, the Distribution Account or the Pre-Funding Account and
made in accordance with this Section 3.05.

            (f)   The Master Servicer shall give at least 30 days advance
notice to the Trustee, each Seller, each Rating Agency and the Depositor of
any proposed change of location of the Certificate Account prior to any change
thereof. The Trustee shall give at least 30 days advance 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 or
the Carryover Reserve Fund prior to any change thereof.

            (g)   Except as otherwise expressly provided in this Agreement, if
any default occurs under any Permitted Investment, the Trustee may and,
subject to Sections 8.01 and 8.02(a)(4), at the request of the Holders of
Certificates representing more than 50% of the Voting Rights or the NIM
Insurer, shall take any action appropriate to enforce payment or performance,
including the institution and prosecution of appropriate proceedings.

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

            To the extent required by the related Mortgage Note, 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 herein shall require the Master Servicer to compel a
Mortgagor to establish an Escrow Account in violation of applicable law.

            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 hereof (with respect to taxes and assessments and
insurance premiums) and 3.10 hereof (with respect to hazard insurance), to
refund to any Mortgagors any sums as may be 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 hereof. The Escrow Accounts shall not be a part
of the Trust Fund.

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

            The Master Servicer shall afford the Depositor, the NIM Insurer
and the Trustee reasonable access to all records and documentation regarding
such Mortgage Loans and all related accounts, insurance policies 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
offices of the Master Servicer designated by it. Upon request, the Master
Servicer 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.

            Upon reasonable advance notice in writing if required by federal
regulation, the Master Servicer will provide to each Certificateholder or
Certificate Owner that 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 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 or Certificate Owner for actual expenses incurred by
the Master Servicer in providing such reports and access.

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

            (a)   The Master Servicer may from time to time make withdrawals
from the Certificate Account for the following purposes:

                  (i)   to pay to the Master Servicer (to the extent not
            previously paid to or withheld by the Master Servicer), as
            servicing compensation in accordance with Section 3.15, that
            portion of any payment of interest that equals the Servicing Fee
            for the period with respect to which such interest payment was
            made, and, as additional servicing compensation to the Master
            Servicer, those other amounts set forth in Section 3.15;

                  (ii)  to reimburse each of the Master Servicer and the
                        Trustee for Advances made by it with respect to the
            Mortgage Loans, such right of reimbursement pursuant to this
            subclause (ii) being limited to amounts received on particular
            Mortgage Loan(s) (including, for this purpose, Liquidation
            Proceeds, Insurance Proceeds and Subsequent Recoveries) that
            represent late recoveries of payments of principal and/or interest
            on such particular Mortgage Loan(s) in respect of which any such
            Advance was made;

                  (iii) [Reserved];

                  (iv)  to reimburse each of the Master Servicer and the
            Trustee for any Nonrecoverable Advance previously made;

                                      109
<PAGE>

                  (v)   to reimburse the Master Servicer from Insurance
            Proceeds for Insured Expenses covered by the related Insurance
            Policy;

                  (vi)  to pay the Master Servicer any unpaid Servicing Fees
            and to reimburse it for any unreimbursed Servicing Advances, the
            Master Servicer's right to reimbursement of Servicing Advances
            pursuant to this subclause (vi) with respect to any Mortgage Loan
            being limited to amounts received on particular Mortgage Loan(s)
            (including, for this purpose, Liquidation Proceeds, Insurance
            Proceeds and Subsequent Recoveries and purchase and repurchase
            proceeds) that represent late recoveries of the payments for which
            such advances were made pursuant to Section 3.01 or Section 3.06;

                  (vii) to pay to the applicable Seller, the Depositor or the
            Master Servicer, as applicable, with respect to each Mortgage Loan
            or property acquired in respect thereof that has been purchased
            pursuant to Section 2.02, 2.03, 2.04 or 3.12, all amounts received
            thereon and not taken into account in determining the related
            Stated Principal Balance of such repurchased Mortgage Loan;

                  (viii) to reimburse the applicable Seller, the Master
            Servicer, the NIM Insurer or the Depositor for expenses incurred
            by any of them in connection with the Mortgage Loans or
            Certificates and reimbursable pursuant to Section 6.03 hereof;
            provided that such amount shall only be withdrawn following the
            withdrawal from the Certificate Account for deposit into the
            Distribution Account pursuant to the following paragraph;

                  (ix)  to pay any lender-paid primary mortgage insurance
            premiums;

                  (x)   to withdraw any amount deposited in the Certificate
            Account and not required to be deposited therein; and

                  (xi)  to clear and terminate the Certificate Account upon
            termination of this Agreement pursuant to Section 9.01 hereof.

            In addition, no later than 1:00 p.m. Pacific time on the
Distribution Account Deposit Date, the Master Servicer shall withdraw from the
Certificate Account and remit to the Trustee the Interest Remittance Amount
and Principal Remittance Amount for each Loan Group, and the Trustee shall
deposit such amount in the Distribution Account.

            The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On
the Closing Date, CHL shall deposit into the Principal Reserve Fund $300.00.
Funds on deposit in the Principal Reserve Fund shall not be invested. The
Principal Reserve Fund shall be treated as an "outside reserve fund" under
applicable Treasury regulations and shall not be part of any REMIC created
under this Agreement.

            On the Business Day before the April 2005 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 A-R
Certificates on such Distribution Date.

<PAGE>

            On the Business Day before the Class PF 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 PF
Certificates on the Class PF Principal Distribution Date. On the Business Day
before the Class PV Principal Distribution Date, the Trustee shall transfer
from the Principal Reserve Fund to the Distribution Account $100.00 and shall
distribute such amount to the Class PV Certificates on the Class PV Principal
Distribution Date. Following the distributions to be made in accordance with
the two preceding sentences, the Trustee shall then terminate the Principal
Reserve Fund.

            The Master Servicer shall keep and maintain separate accounting,
on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to subclauses (i), (ii),
(iv), (v), (vi), (vii) and (viii) above. Prior to making any withdrawal from
the Certificate Account pursuant to subclause (iv), the Master Servicer shall
deliver to the Trustee an Officer's Certificate of a Servicing Officer
indicating the amount of any previous Advance determined by the Master
Servicer to be a Nonrecoverable Advance and identifying the related Mortgage
Loan(s), and their respective portions of such Nonrecoverable Advance.

            (b)   The Trustee shall withdraw funds from the Distribution
Account for distribution to the Certificateholders and the Class AF-5B Insurer
in the manner specified in this Agreement (and to withhold from the amounts so
withdrawn, the amount of any taxes that it is authorized to retain pursuant to
the penultimate paragraph of Section 8.11). In addition, the Trustee may from
time to time make withdrawals from the Distribution Account for the following
purposes:

                  (i)   to pay the Trustee the Trustee Fee on each
            Distribution Date;

                  (ii)  to pay to the Master Servicer, as additional servicing
            compensation, earnings on or investment income with respect to
            funds in or credited to the Distribution Account;

                  (iii) to withdraw pursuant to Section 3.05 any amount
            deposited in the Distribution Account and not required to be
            deposited therein;

                  (iv)  to reimburse the Trustee for any unreimbursed Advances
            made by it pursuant to Section 4.01(d) hereof, such right of
            reimbursement pursuant to this subclause (iv) being limited to (x)
            amounts received on the related Mortgage Loan(s) in respect of
            which any such Advance was made and (y) amounts not otherwise
            reimbursed to the Trustee pursuant to Section 3.08(a)(ii) hereof;

                  (v)   to reimburse the Trustee for any Nonrecoverable
            Advance previously made by the Trustee pursuant to Section 4.01(d)
            hereof, such right of reimbursement pursuant to this subclause (v)
            being limited to amounts not otherwise reimbursed to the Trustee
            pursuant to Section 3.08(a)(iv) hereof; and

                  (vi)  to clear and terminate the Distribution Account upon
            termination of the Agreement pursuant to Section 9.01 hereof.

                                      111
<PAGE>

            (c)   The Trustee shall withdraw funds from the Carryover Reserve
Fund for distribution to the Certificateholders in the manner specified in
this Agreement (and to withhold from the amounts so withdrawn, the amount of
any taxes that it is authorized to retain pursuant to the penultimate
paragraph of Section 8.11). In addition, the Trustee may from time to time
make withdrawals from the Carryover Reserve Fund for the following purposes:

                  (1)   to withdraw any amount deposited in the Carryover
      Reserve Fund and not required to be deposited therein; and

                  (2)   to clear and terminate the Carryover Reserve Fund upon
      termination of the Agreement pursuant to Section 9.01 hereof.

            Section 3.09      [Reserved]

            Section 3.10      Maintenance of Hazard Insurance.

            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 and (ii) the greater of (a) the
outstanding principal balance of the Mortgage Loan and (b) an amount such that
the proceeds of such policy shall be sufficient to prevent the related
Mortgagor and/or 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. The Master Servicer shall also
cause flood insurance to be maintained on property acquired upon foreclosure
or deed in lieu of foreclosure of any Mortgage Loan, to the extent described
below. Pursuant to Section 3.05 hereof, 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 property thus
acquired 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
Liquidation Proceeds or Subsequent Recoveries to the extent permitted by
Section 3.08 hereof. 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 lesser of (i) the original principal balance of the
related Mortgage Loan, (ii) the replacement value of the improvements that are
part of such Mortgaged Property, or (iii) the maximum amount of such insurance
available for the related Mortgaged Property under the Flood Disaster
Protection Act of 1973, as amended.

            Section 3.11      Enforcement of Due-On-Sale  Clauses;  Assumption
                              Agreements.

            (a)   Except as otherwise provided in this Section 3.11(a), when
any property subject to a Mortgage has been or is about to be 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-sale clause, or if coverage
under any Required Insurance Policy would be adversely affected, or if
nonenforcement is otherwise permitted hereunder, the Master Servicer is
authorized, subject to Section 3.11(b), to take or enter into an assumption
and modification agreement from or with the person to whom such property has
been or is about to be conveyed, pursuant to which such person becomes liable
under the Mortgage Note and, unless prohibited by applicable state law, the
Mortgagor remains liable thereon, provided that the Mortgage Loan shall
continue to be covered (if so covered before the Master Servicer enters such
agreement) by the applicable Required Insurance Policies. The Master Servicer,
subject to Section 3.11(b), is also authorized with the prior approval of the
insurers under any Required Insurance Policies to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as Mortgagor and
becomes liable under the Mortgage Note. The Master Servicer shall notify the
Trustee that any such substitution, modification or assumption agreement has
been completed by forwarding to the Co-Trustee the executed original of such
substitution or assumption agreement, which document shall be added to the
related Mortgage File and shall, for all purposes, be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting a part thereof.

            (b)   Subject to the Master Servicer's duty to enforce any
due-on-sale clause to the extent set forth in Section 3.11(a) hereof, in any
case in which a Mortgaged Property has been conveyed to a Person by a
Mortgagor, and such Person is to enter into an assumption agreement or
modification agreement or supplement to the Mortgage Note or Mortgage that
requires the signature of the Trustee, or if an instrument of release signed
by the Trustee is required releasing the Mortgagor from liability on the
Mortgage Loan, the Master Servicer shall prepare and deliver or cause to be
prepared and delivered to the Trustee for signature and shall direct, in
writing, the Trustee to execute the assumption agreement with the Person to
whom the Mortgaged Property is to be conveyed and such modification agreement
or supplement to the Mortgage Note or Mortgage or other instruments as are
reasonable or necessary to carry out the terms of the Mortgage Note or
Mortgage or otherwise to comply with any applicable laws regarding assumptions
or the transfer of the Mortgaged Property to such Person. In connection with
any such assumption, no material term of the Mortgage Note (including, but not
limited to, the Mortgage Rate, the amount of the Scheduled Payment, the
Maximum Mortgage Rate, the Minimum Mortgage Rate, the Gross Margin, the
Initial Periodic Rate Cap, the Subsequent Periodic Rate Cap, the Adjustment
Date and any other term affecting the amount or timing of

                                      113
<PAGE>

payment on the Mortgage Loan) may be changed. In addition, the substitute
Mortgagor and the Mortgaged Property must be acceptable to the Master Servicer
in accordance with its underwriting standards as then in effect. The Master
Servicer shall notify the Trustee that any such substitution or assumption
agreement has been completed by forwarding to the Trustee the original of such
substitution or assumption agreement, which in the case of the original shall
be added to the related Mortgage File and shall, for all purposes, be
considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof. Any fee collected by
the Master Servicer for entering into an assumption or substitution of
liability agreement will be retained by the Master Servicer as additional
servicing compensation.

            Section 3.12      Realization Upon Defaulted Mortgage Loans;
                              Determination of Excess Proceeds and Realized
                              Losses; Repurchase of Certain Mortgage Loans.

            (a)   The Master Servicer may agree to a modification of any
Mortgage Loan (the "Modified Mortgage Loan") if (i) the modification is in
lieu of a refinancing and (ii) the Mortgage Rate on the Modified Mortgage Loan
is approximately a prevailing market rate for newly-originated mortgage loans
having similar terms and (iii) the Master Servicer purchases the Modified
Mortgage Loan from the Trust Fund as described below. Effective immediately
after the modification, and, in any event, on the same Business Day on which
the modification occurs, all interest of the Trustee in the Modified Mortgage
Loan shall automatically be deemed transferred and assigned to the Master
Servicer and all benefits and burdens of ownership thereof, including the
right to accrued interest thereon from the date of modification and the risk
of default thereon, shall pass to the Master Servicer. The Master Servicer
shall promptly deliver to the Trustee a certification of a Servicing Officer
to the effect that all requirements of this paragraph have been satisfied with
respect to the Modified Mortgage Loan. For federal income tax purposes, the
Trustee shall account for such purchase as a prepayment in full of the
Modified Mortgage Loan. The Master Servicer shall deposit the Purchase Price
for any Modified Mortgage Loan in the Certificate Account pursuant to Section
3.05 within one Business Day after the purchase of the Modified Mortgage Loan.
Upon receipt by the Trustee of written notification of any such deposit signed
by a Servicing Officer, the Trustee shall release to the Master Servicer the
related Mortgage File and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as shall be necessary
to vest in the Master Servicer any Modified Mortgage Loan previously
transferred and assigned pursuant hereto. The Master Servicer covenants and
agrees to indemnify the Trust Fund against any liability for any "prohibited
transaction" taxes and any related interest, additions, and penalties imposed
on the Trust Fund established hereunder as a result of any modification of a
Mortgage Loan effected pursuant to this subsection (b), any holding of a
Modified Mortgage Loan by the Trust Fund or any purchase of a Modified
Mortgage Loan by the Master Servicer (but such obligation shall not prevent
the Master Servicer or any other appropriate Person from in good faith
contesting any such tax in appropriate proceedings and shall not prevent the
Master Servicer from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings). The Master Servicer shall have no
right of reimbursement for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest,
and penalties, together with interest thereon, is refunded to the Trust Fund
or the Master Servicer. If the Master Servicer agrees to a modification of any
Mortgage Loan pursuant to this Section 3.12(a), and if

                                      114
<PAGE>

such Mortgage Loan carries a Prepayment Charge provision, the Master Servicer
will deliver to the Trustee the amount of the Prepayment Charge, if any, that
would have been due had such Mortgage Loan been prepaid at the time of such
modification, for deposit into the Certificate Account (not later than 1:00
p.m. Pacific time on the Master Servicer Advance Date immediately succeeding
the date of such modification) for distribution in accordance with the terms
of this Agreement.

            (b)   The Master Servicer shall use reasonable efforts to
foreclose upon or otherwise comparably convert the ownership of properties
securing such of the Mortgage Loans as come into and continue in default and
as to which no satisfactory arrangements can be made for collection of
delinquent payments. In connection with such foreclosure or other conversion,
the Master Servicer shall follow such practices and procedures as it shall
deem necessary or advisable and as shall be normal and usual in its general
mortgage servicing activities and the requirements of the insurer under any
Required Insurance Policy; provided that the Master Servicer shall not be
required to expend its own funds in connection with any foreclosure or towards
the restoration of any property unless it shall determine (i) that such
restoration and/or foreclosure will increase the proceeds of liquidation of
the Mortgage Loan after reimbursement to itself of such expenses and (ii) that
such expenses will be recoverable to it through Liquidation Proceeds
(respecting which it shall have priority for purposes of withdrawals from the
Certificate Account pursuant to Section 3.08 hereof). The Master Servicer
shall be responsible for all other costs and expenses incurred by it in any
such proceedings; provided that it shall be entitled to reimbursement thereof
from the proceeds of liquidation of the related Mortgaged Property and any
related Subsequent Recoveries, as contemplated in Section 3.08 hereof. If the
Master Servicer has knowledge that a Mortgaged Property that the Master
Servicer is contemplating acquiring in foreclosure or by deed-in-lieu of
foreclosure is located within a one-mile radius of any site with environmental
or hazardous waste risks known to the Master Servicer, the Master Servicer
will, prior to acquiring the Mortgaged Property, consider such risks and only
take action in accordance with its established environmental review
procedures.

            With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such
REO Property solely as the Trustee hereunder and not in its individual
capacity. The Master Servicer shall ensure that the title to such REO Property
references this Agreement and the Trustee's capacity thereunder. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall either itself
or through an agent selected by the Master Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Certificateholders, rent
the same, or any part thereof, as the Master Servicer deems to be in the best
interest of the Master Servicer and the Certificateholders for the period
prior to the sale of such REO Property. The Master Servicer shall prepare for
and deliver to the Trustee a statement with respect to each REO Property that
has been rented showing the aggregate rental income received and all expenses
incurred in connection with the management and maintenance of such REO
Property at such times as is necessary to enable the Trustee to comply with
the reporting requirements of the REMIC Provisions. The net monthly rental
income, if any, from such REO Property shall be deposited in the Certificate
Account no later than the close of business on each Determination Date. The
Master Servicer shall perform the tax reporting and withholding

                                      115
<PAGE>

related to foreclosures, abandonments and cancellation of indebtedness income
as specified by Sections 1445, 6050J and 6050P of the Code by preparing and
filing such tax and information returns, as may be required.

            In the event that the Trust Fund acquires any Mortgaged Property
as aforesaid or otherwise in connection with a default or imminent default on
a Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property
as soon as practicable in a manner that maximizes the Liquidation Proceeds,
but in no event later than three years after its acquisition by the Trust Fund
or, at the expense of the Trust Fund, the Master Servicer shall request, more
than 60 days prior to the day on which such three-year period would otherwise
expire, an extension of the three-year grace period. In the event the Trustee
shall have been supplied with an Opinion of Counsel (such opinion not to be an
expense of the Trustee) to the effect that the holding by the Trust Fund of
such Mortgaged Property subsequent to such three-year period will not result
in the imposition of taxes on "prohibited transactions" of the Trust Fund as
defined in section 860F of the Code or cause any REMIC formed hereunder to
fail to qualify as a REMIC at any time that any Certificates are outstanding,
and the Trust Fund may continue to hold such Mortgaged Property (subject to
any conditions contained in such Opinion of Counsel) after the expiration of
such three-year period. Notwithstanding any other provision of this Agreement,
no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed
to continue to be rented) or otherwise used for the production of income by or
on behalf of the Trust Fund in such a manner or pursuant to any terms that
would (i) cause such Mortgaged Property to fail to qualify as "foreclosure
property" within the meaning of section 860G(a)(8) of the Code or (ii) subject
the Trust Fund to the imposition of any federal, state or local income taxes
on the income earned from such Mortgaged Property under section 860G(c) of the
Code or otherwise, unless the Master Servicer has agreed to indemnify and hold
harmless the Trust Fund with respect to the imposition of any such taxes.

            The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of
bringing such a proceeding. The income earned from the management of any
Mortgaged Properties acquired through foreclosure or other judicial
proceeding, net of reimbursement to the Master Servicer for expenses incurred
(including any property or other taxes) in connection with such management and
net of unreimbursed Servicing Fees, Advances, Servicing Advances and any
management fee paid or to be paid with respect to the management of such
Mortgaged Property, shall be applied to the payment of principal of, and
interest on, the related defaulted Mortgage Loans (with interest accruing as
though such Mortgage Loans were still current) and all such income shall be
deemed, for all purposes in this Agreement, to be payments on account of
principal and interest on the related Mortgage Notes and shall be deposited
into the Certificate Account. To the extent the income received during a
Prepayment Period is in excess of the amount attributable to amortizing
principal and accrued interest at the related Mortgage Rate on the related
Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

            The Liquidation Proceeds from any liquidation of a Mortgage Loan
and any Subsequent Recoveries, net of any payment to the Master Servicer as
provided above, shall be deposited in the Certificate Account as provided in
Section 3.05 for distribution on the related

                                      116
<PAGE>

Distribution Date, except that any Excess Proceeds shall be retained by the
Master Servicer as additional servicing compensation.

            The proceeds of any Liquidated Mortgage Loan, as well as any
recovery resulting from a partial collection of Liquidation Proceeds or any
income from an REO Property, will be applied in the following order of
priority: first, to reimburse the Master Servicer for any related unreimbursed
Servicing Advances and Servicing Fees, pursuant to Section 3.08(a)(vi) or this
Section 3.12; second, to reimburse the Master Servicer for any unreimbursed
Advances, pursuant to Section 3.08(a)(ii) or this Section 3.12; third, to
accrued and unpaid interest (to the extent no Advance has been made for such
amount) on the Mortgage Loan or related REO Property, at the Net Mortgage Rate
to the Due Date occurring in the month in which such amounts are required to
be distributed; and fourth, as a recovery of principal of the Mortgage Loan.

            (c)   [Reserved].

            (d)   The Master Servicer, in its sole discretion, shall have the
right to elect (by written notice sent to the Trustee) to purchase for its own
account from the Trust Fund any Mortgage Loan that is 150 days or more
delinquent at a price equal to the Purchase Price; provided, however, that the
Master Servicer may only exercise this right on or before the last day of the
calendar month in which such Mortgage Loan became 150 days delinquent (such
month, the "Eligible Repurchase Month"); provided further, that any such
Mortgage Loan which becomes current but thereafter becomes delinquent may be
purchased by the Master Servicer pursuant to this Section in any ensuing
Eligible Repurchase Month. The Purchase Price for any Mortgage Loan purchased
hereunder shall be deposited in the Certificate Account. Any purchase of a
Mortgage Loan pursuant to this Section 3.12(d) shall be accomplished by
remittance to the Master Servicer for deposit in the Certificate Account of
the Purchase Price. The Trustee, upon receipt of certification from the Master
Servicer of such deposit and a Request for File Release from the Master
Servicer, shall release or cause to be released to the purchaser of such
Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such
Mortgage Loan, in each case without recourse, as shall be necessary to vest in
the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto
and the purchaser of such Mortgage Loan shall succeed to all the Trustee's
right, title and interest in and to such Mortgage Loan and all security and
documents related thereto. Such assignment shall be an assignment outright and
not for security. The purchaser of such Mortgage Loan shall thereupon own such
Mortgage Loan, and all security and documents, free of any further obligation
to the Trustee or the Certificateholders with respect thereto.

            Section 3.13      Co-Trustee to Cooperate; Release of Mortgage
                              Files.

            Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full will be escrowed in
a manner customary for such purposes, the Master Servicer will promptly notify
the Co-Trustee by delivering a Request for File Release. Upon receipt of such
request, the Co-Trustee shall promptly release the related Mortgage File to
the Master Servicer, and the Co-Trustee shall at the Master Servicer's
direction execute and deliver to the Master Servicer the request for
reconveyance, deed of reconveyance or release or satisfaction of mortgage or
such instrument releasing the lien of the Mortgage in each

                                      117
<PAGE>

case provided by the Master Servicer, together with the Mortgage Note with
written evidence of cancellation thereon. The Master Servicer is authorized to
cause the removal from the registration on the MERS(R) System of such Mortgage
and to execute and deliver, on behalf of the Trust Fund and the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation or of partial or full release. No expenses incurred in connection
with any instrument of satisfaction or deed of reconveyance shall be
chargeable to the Certificate Account, the Distribution Account, the Carryover
Reserve Fund or the related subservicing account. From time to time and as
shall be appropriate for the servicing or foreclosure of any Mortgage Loan,
including for such purpose, collection under any policy of flood insurance any
fidelity bond or errors or omissions policy, or for the purposes of effecting
a partial release of any Mortgaged Property from the lien of the Mortgage or
the making of any corrections to the Mortgage Note or the Mortgage or any of
the other documents included in the Mortgage File, the Co-Trustee shall, upon
delivery to the Co-Trustee of a Request for Document Release or a Request for
File Release, as applicable, release the documents specified in such request
or the Mortgage File, as the case may be, to the Master Servicer. Subject to
the further limitations set forth below, the Master Servicer shall cause the
Mortgage File or documents so released to be returned to the Co-Trustee when
the need therefor by the Master Servicer no longer exists, unless the Mortgage
Loan is liquidated and the proceeds thereof are deposited in the Certificate
Account, in which case the Master Servicer shall deliver to the Co-Trustee a
Request for File Release for any remaining documents in the Mortgage File not
in the possession of the Master Servicer.

            If the Master Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this
Agreement, the Master Servicer shall deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity. Notwithstanding the foregoing, the
Master Servicer shall cause possession of any Mortgage File or of the
documents therein that shall have been released by the Co-Trustee to be
returned to the Co-Trustee within 21 calendar days after possession thereof
shall have been released by the Co-Trustee unless (i) the Mortgage Loan has
been liquidated and the Liquidation Proceeds relating to the Mortgage Loan
have been deposited in the Certificate Account, and the Master Servicer shall
have delivered to the Co-Trustee a Request for File Release or (ii) the
Mortgage File or document shall have been delivered to an attorney or to a
public trustee or other public official as required by law for purposes of
initiating or pursuing legal action or other proceedings for the foreclosure
of the Mortgaged Property and the Master Servicer shall have delivered to the
Trustee an Officer's Certificate of a Servicing Officer certifying as to the
name and address of the Person to which the Mortgage File or the documents
therein were delivered and the purpose or purposes of such delivery.

            Section 3.14      Documents, Records and Funds in Possession of
                              Master Servicer to be Held for the Trustee.

            Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Co-Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time

                                      118
<PAGE>

and shall account fully to the Trustee for any funds received by the Master
Servicer or that otherwise are collected by the Master Servicer as Liquidation
Proceeds, Insurance Proceeds or Subsequent Recoveries in respect of any
Mortgage Loan. All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds
or Subsequent Recoveries including but not limited to, any funds on deposit in
the Certificate Account, shall be held by the Master Servicer for and on
behalf of the Trust Fund and shall be and remain the sole and exclusive
property of the Trust Fund, subject to the applicable provisions of this
Agreement. The Master Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Certificate
Account, the Distribution Account, the Carryover Reserve Fund or in any Escrow
Account (as defined in Section 3.06), or any funds that otherwise are or may
become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy,
writ of attachment or other encumbrance, or assert by legal action or
otherwise any claim or right of set off against any Mortgage File or any funds
collected on, or in connection with, a Mortgage Loan, except, however, that
the Master Servicer shall be entitled to set off against and deduct from any
such funds any amounts that are properly due and payable to the Master
Servicer under this Agreement.

            Section 3.15      Servicing Compensation.

            As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain or withdraw from the Certificate Account out of
each payment of interest on a Mortgage Loan included in the Trust Fund an
amount equal to interest at the applicable Servicing Fee Rate on the Stated
Principal Balance of the related Mortgage Loan for the period covered by such
interest payment.

            Additional servicing compensation in the form of any Excess
Proceeds, assumption fees, late payment charges, Prepayment Interest Excess,
and all income and gain net of any losses realized from Permitted Investments
shall be retained by the Master Servicer to the extent not required to be
deposited in the Certificate Account pursuant to Section 3.05 or 3.12(b)
hereof. The Master Servicer shall be required to pay all expenses incurred by
it in connection with its servicing activities hereunder (including payment of
any premiums for hazard insurance, as required by Section 3.10 hereof and
maintenance of the other forms of insurance coverage required by Section 3.10
hereof) and shall not be entitled to reimbursement therefor except as
specifically provided in Sections 3.08 and 3.12 hereof.

            Section 3.16      Access to Certain Documentation.

            The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates and
Certificate Owners and the examiners and supervisory agents of the OTS, the
FDIC and such other authorities, access to the documentation regarding the
Mortgage Loans required by applicable regulations of the OTS and the FDIC.
Such access shall be afforded without charge, but only upon reasonable and
prior written request and during normal business hours at the offices of the
Master Servicer designated by it. Nothing in this Section shall limit the
obligation of the Master Servicer to observe any applicable law prohibiting
disclosure of information regarding the Mortgagors and the failure of

                                      119
<PAGE>

the Master Servicer to provide access as provided in this Section as a result
of such obligation shall not constitute a breach of this Section.

            Section 3.17      Annual Statement as to Compliance.

            The Master Servicer shall deliver to the Depositor and the Trustee
on or before the 80th day after the end of the Master Servicer's fiscal year,
commencing with its 2005 fiscal year, an Officer's Certificate stating, as to
the signer thereof, that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of the performance of the Master
Servicer under this Agreement has been made under such officer's supervision
and (ii) to the best of such officer's knowledge, based on such review, the
Master Servicer has fulfilled all its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of
any such obligation, specifying each such default known to such officer and
the nature and status thereof and (iii) to the best of such officer's
knowledge, each Subservicer has fulfilled all its obligations under its
Subservicing Agreement throughout such year, or, if there has been a default
in the fulfillment of any such obligation specifying each such default known
to such officer and the nature and status thereof. The Trustee shall forward a
copy of each such statement to each Rating Agency. Copies of such statement
shall be provided by the Trustee to any Certificateholder or Certificate Owner
upon request at the Master Servicer's expense, provided such statement is
delivered by the Master Servicer to the Trustee.

            Section 3.18      Annual Independent Public Accountants' Servicing
                              Statement; Financial Statements.

            On or before the later of (i) the 80th day after the end of the
Master Servicer's fiscal year, commencing with its 2005 fiscal year or (ii)
within 30 days of the issuance of the annual audited financial statements
beginning with the audit for the period ending in 2005, the Master Servicer at
its expense shall cause a nationally recognized firm of independent public
accountants (who may also render other services to the Master Servicer, CHL or
any affiliate thereof) that is a member of the American Institute of Certified
Public Accountants to furnish a report to the Trustee, the Depositor and CHL
in compliance with the Uniform Single Attestation Program for Mortgage
Bankers. Copies of such report shall be provided by the Trustee to any
Certificateholder or Certificate Owner upon request at the Master Servicer's
expense, provided such report is delivered by the Master Servicer to the
Trustee. Upon written request, the Master Servicer shall provide to the
Certificateholders or Certificate Owners its publicly available annual
financial statements (or the Master Servicer's parent company's publicly
available annual financial statements, as applicable), if any, promptly after
they become available.

            Section 3.19      The Corridor Contracts.

            CHL shall cause The Bank of New York to enter into the Corridor
Contract Administration Agreement and shall assign all of its right, title and
interest in and to the interest rate corridor transactions evidenced by the
Corridor Contracts to, and shall cause all of its obligations in respect of
such transactions to be assumed by, the Corridor Contract Administrator, on
the terms and conditions set forth in the Corridor Contract Assignment
Agreement. The Trustee's rights to receive certain proceeds of the Corridor
Contracts as provided in the Corridor Contract Administration Agreement will
be an asset of the Trust Fund

                                      120
<PAGE>

but will not be an asset of any REMIC. The Trustee shall deposit any amounts
received from time to time with respect to any Corridor Contract into the
Carryover Reserve Fund. The Master Servicer shall deposit any amounts received
on behalf of the Trustee from time to time with respect to any Corridor
Contract into the Carryover Reserve Fund.

            No later than two Business Days following each Distribution Date,
the Trustee shall provide the Corridor Contract Administrator with information
regarding the aggregate Certificate Principal Balance of the Class(es) of
Certificates related to each Corridor Contract after all distributions on such
Distribution Date.

            The Trustee shall direct the Corridor Contract Administrator to
terminate a Corridor Contract upon the occurrence of certain events of default
or termination events to the extent specified thereunder. Upon any such
termination, the Corridor Contract Counterparty will be obligated to pay the
Corridor Contract Administrator an amount in respect of such termination, and
the portion of such amount that is distributable to the Trust Fund pursuant to
the Corridor Contract Administration Agreement and received by the Trustee or
the Master Servicer for the benefit of the Trust Fund, as the case may be, in
respect of such termination shall be deposited and held in the Carryover
Reserve Fund to pay Net Rate Carryover for the applicable Classes of
Certificates as provided in Section 4.04(e) on the Distribution Dates
following such termination to and including the applicable Corridor Contract
Termination Date, but shall not be available for distribution to the
applicable Class of Class C Certificates pursuant to Section 4.07(c) or to CHL
pursuant to Section 4.07(c) until such applicable Corridor Contract
Termination Date. On the Corridor Contract Termination Date for the Class AF-1
Corridor Contract, Class 1-AV Corridor Contract, Class 2-AV Corridor Contract,
Class 3-AV Corridor Contract and Adjustable Rate Subordinate Corridor
Contract, after all other distributions on such date, if any such amounts in
respect of early termination of the Class AF-1 Corridor Contract, Class 1-AV
Corridor Contract, Class 2-AV Corridor Contract, Class 3-AV Corridor Contract
or the Adjustable Rate Subordinate Corridor Contract remain in the Carryover
Reserve Fund, such amounts shall be distributed by the Trustee to (i) in the
case of any such amounts relating to the Class AF-1 Corridor Contract, the
Class CF Certificates, and (ii) in the case of any such amounts relating to
the Class 1-AV Corridor Contract, Class 2-AV Corridor Contract, Class 3-AV
Corridor Contact and Adjustable Rate Subordinate Corridor Contract, the CV
Certificates.

            Section 3.20      Prepayment Charges.

            (a)   Notwithstanding anything in this Agreement to the contrary,
in the event of a Principal Prepayment in full or in part of a Mortgage Loan,
the Master Servicer may not waive any Prepayment Charge or portion thereof
required by the terms of the related Mortgage Note unless (i) such Mortgage
Loan is in default or the Master Servicer believes that such a default is
imminent, and the Master Servicer determines that such waiver would maximize
recovery of Liquidation Proceeds for such Mortgage Loan, taking into account
the value of such Prepayment Charge, or (ii) (A) the enforceability thereof is
limited (1) by bankruptcy, insolvency, moratorium, receivership, or other
similar law relating to creditors' rights generally or (2) due to acceleration
in connection with a foreclosure or other involuntary payment, or (B) the
enforceability is otherwise limited or prohibited by applicable law. In the
event of a Principal Prepayment in full or in part with respect to any
Mortgage Loan, the Master Servicer shall deliver to the Trustee an Officer's
Certificate substantially in the form of Exhibit T no later

                                      121
<PAGE>

than the third Business Day following the immediately succeeding Determination
Date with a copy to the Class P Certificateholders. If the Master Servicer has
waived or does not collect all or a portion of a Prepayment Charge relating to
a Principal Prepayment in full or in part due to any action or omission of the
Master Servicer, other than as provided above, the Master Servicer shall
deliver to the Trustee, together with the Principal Prepayment in full or in
part, the amount of such Prepayment Charge (or such portion thereof as had
been waived) for deposit into the Certificate Account (not later than 1:00
p.m. Pacific time on the immediately succeeding Master Servicer Advance Date,
in the case of such Prepayment Charge) for distribution in accordance with the
terms of this Agreement.

            (b)   Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing subsection (a), the party
discovering the breach shall give prompt written notice to the other parties.

            (c)   CHL represents and warrants to the Depositor and the
Trustee, as of the Closing Date and each Subsequent Transfer Date, that the
information in the Prepayment Charge Schedule (including the attached
prepayment charge summary) is complete and accurate in all material respects
at the dates as of which the information is furnished and each Prepayment
Charge is permissible and enforceable in accordance with its terms under
applicable state law, except as the enforceability thereof is limited due to
acceleration in connection with a foreclosure or other involuntary payment.

            (d)   Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing clause (c) that materially
and adversely affects right of the Holders of the Class P Certificates to any
Prepayment Charge, the party discovering the breach shall give prompt written
notice to the other parties. Within 60 days of the earlier of discovery by the
Master Servicer or receipt of notice by the Master Servicer of breach, the
Master Servicer shall cure the breach in all material respects or shall pay
into the Certificate Account the amount of the Prepayment Charge that would
otherwise be due from the Mortgagor, less any amount representing such
Prepayment Charge previously collected and paid by the Master Servicer into
the Certificate Account.

                                  ARTICLE IV.
               DISTRIBUTIONS AND ADVANCES BY THE MASTER SERVICER

            Section 4.01      Advances; Remittance Reports.

            (a)   Within two Business Days after each Determination Date, the
Master Servicer shall deliver to the Trustee by facsimile or electronic mail
(or by such other means as the Master Servicer and the Trustee, as the case
may be, may agree from time to time) a Remittance Report with respect to the
related Distribution Date. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Master Servicer.

            (b)   Subject to the conditions of this Article IV, the Master
Servicer, as required below, shall make an Advance and deposit such Advance in
the Certificate Account. Each such Advance shall be remitted to the
Certificate Account no later than 1:00 p.m. Pacific

                                      122
<PAGE>

time on the Master Servicer Advance Date in immediately available funds. The
Trustee will provide notice to the Master Servicer by facsimile by the close
of business on any Master Servicer Advance Date in the event that the amount
remitted by the Master Servicer to the Trustee on the Distribution Account
Deposit Date is less than the Advances required to be made by the Master
Servicer for such Distribution Date. The Master Servicer shall be obligated to
make any such Advance only to the extent that such advance would not be a
Nonrecoverable Advance. If the Master Servicer shall have determined that it
has made a Nonrecoverable Advance or that a proposed Advance or a lesser
portion of such Advance would constitute a Nonrecoverable Advance, the Master
Servicer shall deliver (i) to the Trustee for the benefit of the
Certificateholders funds constituting the remaining portion of such Advance,
if applicable, and (ii) to the Depositor, each Rating Agency and the Trustee
an Officer's Certificate setting forth the basis for such determination.

            (c)   In lieu of making all or a portion of such Advance from its
own funds, the Master Servicer may (i) cause to be made an appropriate entry
in its records relating to the Certificate Account that any Amount Held for
Future Distributions has been used by the Master Servicer in discharge of its
obligation to make any such Advance and (ii) transfer such funds from the
Certificate Account to the Distribution Account. Any funds so applied and
transferred shall be replaced by the Master Servicer by deposit in the
Certificate Account no later than the close of business on the Business Day
immediately preceding the Distribution Date on which such funds are required
to be distributed pursuant to this Agreement. The Master Servicer shall be
entitled to be reimbursed from the Certificate Account for all Advances of its
own funds made pursuant to this Section as provided in Section 3.08. The
obligation to make Advances with respect to any Mortgage Loan shall continue
until such Mortgage Loan is paid in full or the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Trustee pursuant to any applicable
provision of this Agreement, except as otherwise provided in this Section
4.01.

            (d)   If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to
give written notice thereof to the Trustee (each such notice a "Trustee
Advance Notice"; and such notice may be given by facsimile), not later than
3:00 p.m., New York time, on the Business Day immediately preceding the
related Master Servicer Advance Date, specifying the amount that it will be
unable to deposit (each such amount an "Advance Deficiency") and certifying
that such Advance Deficiency constitutes an Advance hereunder and is not a
Nonrecoverable Advance. If the Trustee receives a Trustee Advance Notice on or
before 3:30 p.m., (New York time) on a Master Servicer Advance Date, the
Trustee shall, not later than 3:00 p.m., (New York time), on the related
Distribution Date, deposit in the Distribution Account an amount equal to the
Advance Deficiency identified in such Trustee Advance Notice unless it is
prohibited from so doing by applicable law. Notwithstanding the foregoing, the
Trustee shall not be required to make such deposit if the Trustee shall have
received written notification from the Master Servicer that the Master
Servicer has deposited or caused to be deposited in the Certificate Account an
amount equal to such Advance Deficiency. All Advances made by the Trustee
pursuant to this Section 4.01(d) shall accrue interest on behalf of the
Trustee at the Trustee Advance Rate from and including the date such Advances
are made to but excluding the date of repayment, with such interest being an
obligation of the Master Servicer and not the Trust Fund. The Master Servicer
shall reimburse the Trustee for the amount

                                      123
<PAGE>

of any Advance made by the Trustee pursuant to this Section 4.01(d) together
with accrued interest, not later than 6:00 p.m. (New York time) on the
Business Day following the related Distribution Date. In the event that the
Master Servicer does not reimburse the Trustee in accordance with the
requirements of the preceding sentence, the Trustee shall immediately (i)
terminate all of the rights and obligations of the Master Servicer under this
Agreement in accordance with Section 7.01 and (ii) subject to the limitations
set forth in Section 3.04, assume all of the rights and obligations of the
Master Servicer hereunder.

            (e)   The Master Servicer shall, not later than the close of
business on the second Business Day immediately preceding each Distribution
Date, deliver to the Trustee a report (in form and substance reasonably
satisfactory to the Trustee) that indicates (i) the Mortgage Loans with
respect to which the Master Servicer has determined that the related Scheduled
Payments should be advanced and (ii) the amount of the related Scheduled
Payments. The Master Servicer shall deliver to the Trustee on the related
Master Servicer Advance Date an Officer's Certificate of a Servicing Officer
indicating the amount of any proposed Advance determined by the Master
Servicer to be a Nonrecoverable Advance.

            Section 4.02      Reduction of Servicing Compensation in
                              Connection with Prepayment Interest Shortfalls.

            In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall, the Master Servicer shall remit any related Compensating
Interest as part of the related Interest Remittance Amount as provided in this
Agreement. The Master Servicer shall not be entitled to any recovery or
reimbursement for Compensating Interest from the Depositor, the Trustee, any
Seller, the Trust Fund or the Certificateholders.

            Section 4.03      [Reserved].

                              Insurer.

            (a)  If, on the third Business Day before any Distribution Date,
the Trustee determines that there will be a Deficiency Amount for such
Distribution Date, the Trustee shall determine the amount of any such
deficiency and shall give notice to the Class AF-5B Insurer by telephone or
telecopy of the amount of such deficiency, confirmed in writing by notice

p.m., New York time on such third Business Day. The Trustee's responsibility
for delivering the notice to the Class AF-5B Insurer as provided in the
preceding sentence is limited to the availability, timeliness and accuracy of
the information provided by the Master Servicer.

            (b)  In the event the Trustee receives a certified copy of an order

on a Class AF-5B Certificate has been voided in whole or in part as a
preference payment under applicable bankruptcy law, the Trustee shall (i)
promptly notify the Class AF-5B Insurer and (ii) comply with the provisions of
the Class AF-5B Policy, to obtain payment by the Class AF-5B Insurer of such

Holders of the Class AF-5B Certificates so affected that, in the event that
any such Holder's scheduled payment is so recovered, such Holder will be
entitled to payment pursuant to the terms of the Class AF-5B Policy, a copy of

shall furnish to the Class AF-5B Insurer its records listing the payments on
the affected Class AF-5B Certificates, if any, that have been made by the

which such payments were made by the Trustee.

            (c)  At the time of the execution hereof, and for the purposes
hereof, the Trustee shall establish a special purpose trust account in the
name of the Trustee for the benefit of Holders of the Class AF-5B Certificates
(the "Class AF-5B Policy Payments Account") over which the Trustee shall have
exclusive control and sole right of withdrawal. The Class AF-5B Policy
Payments Account shall be an Eligible Account. The Trustee shall deposit any
amount paid under the Class AF-5B Policy into the Class AF-5B Policy Payments
Account and distribute

                                     149
<PAGE>

such amount only for the purposes of making the payments to Holders of the
Class AF-5B Certificates, in respect of the related Deficiency Amount for
which the related claim was made under the Class AF-5B Policy. Such amounts
shall be allocated by the Trustee to Holders of Class AF-5B Certificates
affected by such shortfalls in the same manner as principal and interest
payments are to be allocated with respect to such Certificates pursuant to
Section 4.04. It shall not be necessary for such payments to be made by checks
or wire transfers separated from the checks or wire transfers used to make
regular payments hereunder with funds withdrawn from the Distribution Account.
However, any payments made on the Class AF-5B Certificates from funds in the
Class AF-5B Policy Payments Account shall be noted as provided in subsection
(e) below. Funds held in the Class AF-5B Policy Payments Account shall not be
invested by the Trustee.

            (d)  Any funds received from the Class AF-5B Insurer for deposit
into the Class AF-5B Policy Payments Account pursuant to the Class AF-5B
Policy in respect of a Distribution Date or otherwise as a result of any claim
under the Class AF-5B Policy shall be applied by the Trustee directly to the
payment in full (i) of the related Deficiency Amount on such Distribution Date
or (ii) of other amounts payable under the Class AF-5B Policy. Funds received
by the Trustee as a result of any claim under the Class AF-5B Policy shall be
used solely for payment to the Holders of the Class AF-5B Certificates and may
not be applied for any other purpose, including, without limitation,
satisfaction of any costs, expenses or liabilities of the Trustee, the Master
Servicer or the Trust Fund. Any funds remaining in the Class AF-5B Policy
Payments Account on the first Business Day after each Distribution Date shall
be remitted promptly to the Class AF-5B Insurer in accordance with the
instructions set forth in Section 4.04(i).

            (e)  The Trustee shall keep complete and accurate records in
respect of (i) all funds remitted to it by the Class AF-5B Insurer and
deposited into the Class AF-5B Policy Payments Account and (ii) the allocation
of such funds to (A) payments of interest on and principal in respect of any
Class AF-5B Certificates and (B) the amount of funds available to make
distributions on the Class AF-5B Certificates pursuant to Sections 4.04(a),
(b) and (d). The Class AF-5B Insurer shall have the right to inspect such
records at reasonable times during normal business hours upon three Business
Days' prior notice to the Trustee.

            (f)  The Trustee acknowledges, and each Holder of a Class AF-5B
Certificate by its acceptance of the Class AF-5B Certificate agrees, that,
without the need for any further action on the part of the Class AF-5B Insurer
or the Trustee, to the extent the Class AF-5B Insurer makes payments, directly
or indirectly, on account of principal of or interest on any Class AF-5B
Certificates, the Class AF-5B Insurer will be fully subrogated to the rights
of the Holders of such Class AF-5B Certificates to receive such principal and
interest from the Trust Fund. The Holders of the Class AF-5B Certificates, by
acceptance of the Class AF-5B Certificates, assign their rights as Holders of
the Class AF-5B Certificates to the extent of the Class AF-5B Insurer's
interest with respect to amounts paid under the Class AF-5B Policy. Anything
herein to the contrary notwithstanding, solely for purposes of determining the
Class AF-5B Insurer's rights, as applicable, as subrogee for payments
distributable pursuant to Section 4.04, any payment with respect to
distributions to the Class AF-5B Certificates which is made with funds
received pursuant to the terms of the Class AF-5B Policy shall not be
considered payment of the Class AF-5B Certificates from the Trust Fund and
shall not result in

                                     150

the distribution or the provision for the distribution in reduction of the
Certificate Principal Balance of the Class AF-5B Certificates within the

either of the following as to which it has actual knowledge: (A) the
commencement of any proceeding by or against the Depositor commenced under the
United States bankruptcy code or any other applicable bankruptcy, insolvency,
receivership, rehabilitation or similar law (an "Insolvency Proceeding") and
(B) the making of any claim in connection with any Insolvency Proceeding
seeking the avoidance as a preferential transfer (a "Preference Claim") of any
distribution made with respect to the Class AF-5B Certificates as to which it
has actual knowledge. Each Holder of a Class AF-5B Certificate, by its
purchase of Class AF-5B Certificates, and the Trustee hereby agrees that the
Class AF-5B Insurer (so long as no Class AF-5B Insurer Default exists) may at
any time during the continuation of any proceeding relating to a Preference
Claim direct all matters relating to such Preference Claim, including, without
limitation, (i) the direction of any appeal of any order relating to any
Preference Claim and (ii) the posting of any surety, supersedes or performance
bond pending any such appeal. In addition and without limitation of the
foregoing, the Class AF-5B Insurer shall be subrogated to the rights of the
Trustee and each Holder of a Class AF-5B Certificate in the conduct of any
Preference Claim, including, without limitation, all rights of any party to an
adversary proceeding action with respect to any court order issued in
connection with any such Preference Claim.

            (i)  The Master Servicer shall designate a Class AF-5B Insurer
Contact Person who shall be available to the Class AF-5B Insurer to provide
reasonable access to information regarding the Mortgage Loans. The initial

            (j)  The Trustee shall surrender the Class AF-5B Policy to the
Class AF-5B Insurer for cancellation upon the reduction of the Certificate
Principal Balance of the Class AF-5B Certificates to zero.

            (k)  The Trustee shall send to the Class AF-5B Insurer the reports
prepared pursuant to Sections 3.17 and 3.18 and the statements prepared
pursuant to Section 4.05, as well as any other statements or communications
sent to Holders of the Class AF-5B Certificates, in each case at the same time
such reports, statements and communications are otherwise sent.

            (l)  For so long as there is no continuing default by the Class
AF-5B Insurer under its obligations under the Class AF-5B Policy (a "Class
AF-5B Insurer Default"), each Holder of a Class AF-5B Certificate agrees that
the Class AF-5B Insurer shall be treated by the Depositor, the Master Servicer
and the Trustee as if the Class AF-5B Insurer were the Holder of all of the
Class AF-5B Certificates, for the purpose (and solely for the purpose) of the
giving of any consent, the making of any direction or the exercise of any
voting or other control rights otherwise given to the Holders of the Class
AF-5B Certificates hereunder.

the Credit Comeback Excess Account and made in accordance with this Section
4.08. The Credit Comeback Excess Account shall not constitute an asset of any
REMIC created hereunder. The Class CF Certificates shall evidence ownership of
the Credit Comeback Excess Account for federal tax purposes.

(1)   The Tax Matters Person Certificate may be issued in a denomination of
      $0.05.

            The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by an authorized officer. Certificates
bearing the manual or facsimile signatures of individuals who were, at the
time when such signatures were affixed, authorized to sign on

                                     155
<PAGE>

behalf of the Trustee shall bind the Trustee, notwithstanding that such
individuals or any of them have ceased to be so authorized prior to the
authentication and delivery of such Certificates or did not hold such offices
at the date of such authentication and delivery. No Certificate shall be
entitled to any benefit under this Agreement, or be valid for any purpose,
unless there appears on such Certificate a certificate of authentication
substantially in the form set forth as attached hereto executed by the Trustee
by manual signature, and such certificate of authentication upon any
Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication. On the Closing
Date, the Trustee shall authenticate the Certificates to be issued at the
written direction of the Depositor, or any affiliate thereof.

            The Depositor shall provide, or cause to be provided, to the
Trustee on a continuous basis, an adequate inventory of Certificates to
facilitate transfers.

            Section 5.02      Certificate  Register;  Registration of Transfer
                              and Exchange of Certificates.

            (a)  The Trustee shall maintain a Certificate Register for the
Trust Fund in which, subject to the provisions of subsections (b) and (c)
below and to such reasonable regulations as it may prescribe, the Trustee
shall provide for the registration of Certificates and of Transfers and
exchanges of Certificates as herein provided. Upon surrender for registration
of Transfer of any Certificate, the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same Class and of like aggregate Percentage Interest.

            At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate, and deliver the Certificates that the Certificateholder making
the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Trustee duly
executed by the Holder thereof or his attorney duly authorized in writing.

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

            All Certificates surrendered for registration of Transfer or
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

            (b)  No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an

                                     156
<PAGE>

exemption from the Securities Act and such state securities laws, in order to
assure compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such
Certificateholder's prospective transferee shall (except in connection with
any transfer of a Private Certificate to an affiliate of the Depositor (either
directly or through a nominee) on or about the Closing Date) each certify to
the Trustee in writing the facts surrounding the Transfer in substantially the
forms set forth in Exhibit J-2 and, in the case of a Class A-R Certificate,
Exhibit J-1 (the "Transferor Certificate") and (i) deliver a letter in
substantially the form of either Exhibit K (the "Investment Letter") or
Exhibit L (the "Rule 144A Letter") or (ii) there shall be delivered to the
Trustee at the expense of the Certificateholder desiring to effect such
transfer an Opinion of Counsel that such Transfer may be made pursuant to an
exemption from the Securities Act; provided, however, that in the case of the
delivery of an Investment Letter in connection with the transfer of any Class
C or Class P Certificate to a transferee that is formed with the purpose of
issuing notes backed by such Class C or Class P Certificate, as the case may
be, clause (b) and (c) of the form of Investment Letter shall not be
applicable and shall be deleted by such transferee. The Depositor shall
provide to any Holder of a Private Certificate and any prospective transferee
designated by any such Holder, information regarding the related Certificates
and the Mortgage Loans and such other information as shall be necessary to
satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer
of any such Certificate without registration thereof under the Securities Act
pursuant to the registration exemption provided by Rule 144A. The Trustee, the
Co-Trustee and the Master Servicer shall cooperate with the Depositor in
providing the Rule 144A information referenced in the preceding sentence,
including providing to the Depositor such information regarding the
Certificates, the Mortgage Loans and other matters regarding the Trust Fund as
the Depositor shall reasonably request to meet its obligation under the
preceding sentence. Each Holder of a Private Certificate desiring to effect
such Transfer shall, and does hereby agree to, indemnify the Trustee, the
Co-Trustee, the Depositor, the Trust Fund, each Seller, the Master Servicer
and the NIM Insurer against any liability that may result if the Transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No Transfer of an ERISA-Restricted Certificate (other than a
transfer of an ERISA-Restricted Certificate to an affiliate of the Depositor
(either directly or through a nominee) on or about the Closing Date) shall be
made unless the Trustee shall have received either (i) a representation from
the transferee of such Certificate acceptable to and in form and substance
satisfactory to the Trustee (in the event such Certificate is a Private
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit
K or Exhibit L, or in the event such Certificate is a Residual Certificate,
such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit
I-1), to the effect that (x) such transferee is not an employee benefit plan
or arrangement subject to Section 406 of ERISA or a plan or arrangement
subject to Section 4975 of the Code, or a Person acting on behalf of any such
plan or arrangement or using the assets of any such plan or arrangement, or
(y) in the case of an ERISA-Restricted Certificate that has been the subject
of an ERISA-Qualifying Underwriting, a representation that the transferee is
an insurance company which is purchasing such Certificate with funds contained
in an "insurance company general account" (as such term is defined in section
V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60")) and that
the purchase and holding of such Certificate satisfy the requirements for
exemptive relief under Sections I and III of PTCE 95-60 or (ii) in the case of
any ERISA-Restricted Certificate

                                     157
<PAGE>

presented for registration in the name of an employee benefit plan or
arrangement subject to ERISA, or a plan or arrangement subject to Section 4975
of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or arrangement or any other person acting on behalf
of any such plan or arrangement, an Opinion of Counsel satisfactory to the
Trustee, addressed to the Trustee and the Master Servicer, to the effect that
the purchase and holding of such ERISA-Restricted Certificate will not result
in a non-exempt prohibited transaction under ERISA or the Code and will not
subject the Trustee or the Master Servicer to any obligation in addition to
those expressly undertaken in this Agreement, which Opinion of Counsel shall
not be an expense of the Trustee, the Master Servicer, or the Trust Fund. For
purposes of the preceding sentence, one of such representations, as
appropriate, shall be deemed to have been made to the Trustee by the
transferee's acceptance of an ERISA-Restricted Certificate (or the acceptance
by a Certificate Owner of the beneficial interest in any such Class of
ERISA-Restricted Certificates) unless the Trustee shall have received from the
transferee an Opinion of Counsel as described in clause (ii) or a
representation letter acceptable in form and substance to the Trustee.
Notwithstanding anything else to the contrary herein, any purported transfer
of an ERISA-Restricted Certificate to or on behalf of an employee benefit plan
subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code
without the delivery to the Trustee of an Opinion of Counsel satisfactory to
the Trustee meeting the requirements of clause (i) of the first sentence of
this paragraph as described above shall be void and of no effect. The Trustee
shall be under no liability to any Person for any registration of transfer of
any ERISA-Restricted Certificate that is in fact not permitted by this Section
5.02(b) or for making any payments due on such Certificate to the Holder
thereof or taking any other action with respect to such Holder under the
provisions of this Agreement so long as the Trustee, with respect to the
transfer of such Classes of Certificates, required delivery of such
certificates and other documentation or evidence as are expressly required by
the terms of this Agreement and examined such certificates and other
documentation or evidence to determine compliance as to form with the express
requirements hereof. The Trustee shall be entitled, but not obligated, to
recover from any Holder of any ERISA-Restricted Certificate that was in fact
an employee benefit plan or arrangement subject to Section 406 of ERISA or a
plan or arrangement subject to Section 4975 of the Code or a Person acting on
behalf of any such plan or arrangement at the time it became a Holder or, at
such subsequent time as it became such a plan or arrangement or Person acting
on behalf of such a plan or arrangement, all payments made on such
ERISA-Restricted Certificate at and after either such time. Any such payments
so recovered by the Trustee shall be paid and delivered by the Trustee to the
last preceding Holder of such Certificate that is not such a plan or
arrangement or Person acting on behalf of a plan or arrangement.

            (c)  Each Person who has or who acquires any Ownership Interest in
a Class A-R Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the following
provisions, and the rights of each Person acquiring any Ownership Interest in
a Class A-R Certificate are expressly subject to the following provisions:

                 (1)   Each Person holding or acquiring any Ownership Interest
      in a Class A-R Certificate shall be a Permitted Transferee and shall
      promptly notify the Trustee of any change or impending change in its
      status as a Permitted Transferee.

                                     158
<PAGE>

                 (2)   Except in connection with (i) the registration of the
      Tax Matters Person Certificate in the name of the Trustee or (ii) any
      registration in the name of, or transfer of a Class A-R Certificate to,
      an affiliate of the Depositor (either directly or through a nominee) on
      or about the Closing Date, no Ownership Interest in a Class A-R
      Certificate may be registered or transferred, and the Trustee shall not
      register the Transfer of any Class A-R Certificate unless, the Trustee
      shall have been furnished with an affidavit (a "Transfer Affidavit") of
      the initial owner or the proposed transferee in the form attached hereto
      as Exhibit I-1.

                 (3)   Each Person holding or acquiring any Ownership Interest
      in a Class A-R Certificate shall agree (A) to obtain a Transfer
      Affidavit from any other Person to whom such Person attempts to Transfer
      its Ownership Interest in a Class A-R Certificate, (B) to obtain a
      Transfer Affidavit from any Person for whom such Person is acting as
      nominee, trustee or agent in connection with any Transfer of a Class A-R
      Certificate and (C) not to Transfer its Ownership Interest in a Class
      A-R Certificate, or to cause the Transfer of an Ownership Interest in a
      Class A-R Certificate to any other Person, if it has actual knowledge
      that such Person is not a Permitted Transferee or that such Transfer
      Affidavit is false.

                 (4)   Any attempted or purported Transfer of any Ownership
      Interest in a Class A-R Certificate in violation of the provisions of
      this Section 5.02(c) shall be absolutely null and void and shall vest no
      rights in the purported Transferee. If any purported transferee shall
      become a Holder of a Class A-R Certificate in violation of the
      provisions of this Section 5.02(c), then the last preceding Permitted
      Transferee shall be restored to all rights as Holder thereof retroactive
      to the date of registration of Transfer of such Class A-R Certificate.
      The Trustee shall be under no liability to any Person for any
      registration of Transfer of a Class A-R Certificate that is in fact not
      permitted by Section 5.02(b) and this Section 5.02(c) or for making any
      payments due on such Certificate to the Holder thereof or taking any
      other action with respect to such Holder under the provisions of this
      Agreement so long as the Transfer was registered after receipt of the
      related Transfer Affidavit and Transferor Certificate. The Trustee shall
      be entitled but not obligated to recover from any Holder of a Class A-R
      Certificate that was in fact not a Permitted Transferee at the time it
      became a Holder or, at such subsequent time as it became other than a
      Permitted Transferee, all payments made on such Class A-R Certificate at
      and after either such time. Any such payments so recovered by the
      Trustee shall be paid and delivered by the Trustee to the last preceding
      Permitted Transferee of such Certificate.

                 (5)   The Master Servicer shall use its best efforts to make
      available, upon receipt of written request from the Trustee, all
      information necessary to compute any tax imposed under section 860E(e)
      of the Code as a result of a Transfer of an Ownership Interest in a
      Class A-R Certificate to any Holder who is not a Permitted Transferee.

            The restrictions on Transfers of a Class A-R Certificate set forth
in this section 5.02(c) shall cease to apply (and the applicable portions of
the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of

Counsel, which Opinion of Counsel shall not be an expense of the Trustee, any
Seller or the Master Servicer, to the effect that the elimination of such
restrictions will not cause any REMIC formed hereunder to fail to qualify as a
REMIC at any time that the Certificates are outstanding or result in the
imposition of any tax on the Trust Fund, a Certificateholder or another
Person. Each Person holding or acquiring any Ownership Interest in a Class A-R
Certificate, by acceptance of its Ownership Interest, shall be deemed to
consent to any amendment of this Agreement that, based on an Opinion of
Counsel furnished to the Trustee, is reasonably necessary (a) to ensure that
the record ownership of, or any beneficial interest in, a Class A-R
Certificate is not transferred, directly or indirectly, to a Person that is
not a Permitted Transferee and (b) to provide for a means to compel the
Transfer of a Class A-R Certificate that is held by a Person that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

            (d)  The preparation and delivery of all affidavits, certifications
and opinions referred to above in this section 5.02 shall not be an expense of
the Trust Fund, the Trustee, the Depositor, any Seller or the Master Servicer.

            Section 5.03      Mutilated, Destroyed, Lost or Stolen Certificates.

            If (a) any mutilated Certificate is surrendered to the Trustee, or
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and of the ownership thereof and (b) there is
delivered to the Master Servicer and the Trustee (and with respect to the
Class AF-5B Certificates, the Class AF-5B Insurer) such security or indemnity
as may be required by them to save each of them harmless, then, in the absence
of notice to the Trustee that such Certificate has been acquired by a bona
fide purchaser, the Trustee shall execute, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like Class, tenor and Percentage Interest.
In connection with the issuance of any new Certificate under this Section
5.03, the Trustee may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith. Any replacement Certificate issued pursuant to this Section 5.03
shall constitute complete and indefeasible evidence of ownership in the Trust
Fund, as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time. All Certificates surrendered to the
Trustee under the terms of this Section 5.03 shall be canceled and destroyed
by the Trustee in accordance with its standard procedures without liability on
its part.

            Section 5.04      Persons Deemed Owners.

            The Master Servicer, the Trustee, the NIM Insurer, the Class AF-5B
Insurer and any agent of the Master Servicer, the Trustee, the NIM Insurer or
the Class AF-5B Insurer may treat the person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions as provided in this Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Trustee, the NIM Insurer or
the Class AF-5B Insurer or any agent of the Master Servicer, the Trustee, the
NIM Insurer or the Class AF-5B Insurer shall be affected by any notice to the
contrary.

            Section 5.05      Access to List of Certificateholders' Names and
                              Addresses.

            If three or more Certificateholders or Certificate Owners (a)
request such information in writing from the Trustee, (b) state that such
Certificateholders or Certificate Owners desire to communicate with other
Certificateholders or Certificate Owners with respect to their rights under
this Agreement or under the Certificates and (c) provide a copy of the
communication that such Certificateholders or Certificate Owners propose to
transmit or if the Depositor or Master Servicer shall request such information
in writing from the Trustee, then the Trustee shall, within ten Business Days
after the receipt of such request, provide the Depositor, the Master Servicer
or such Certificateholders or Certificate Owners at such recipients' expense
the most recent list of the Certificateholders of the Trust Fund held by the
Trustee, if any. The Depositor and every Certificateholder or Certificate
Owner, by receiving and holding a Certificate, agree that the Trustee shall
not be held accountable by reason of the disclosure of any such information as
to the list of the Certificateholders hereunder, regardless of the source from
which such information was derived.

            Section 5.06      Book-Entry Certificates.

            The Book-Entry Certificates, upon original issuance, shall be
issued in the form of one typewritten Certificate (or more than one, if
required by the Depository) for each Class of such Certificates, to be
delivered to the Depository by or on behalf of the Depositor. Such
Certificates shall initially be registered on the Certificate Register in the
name of the Depository or its nominee, and no Certificate Owner of such
Certificates will receive a definitive certificate representing such
Certificate Owner's interest in such Certificates, except as provided in
Section 5.08. Unless and until definitive, fully registered Certificates
("Definitive Certificates") have been issued to the Certificate Owners of such
Certificates pursuant to Section 5.08:

            (a)  the provisions of this Section shall be in full force and
effect;

            (b)  the Depositor, the Sellers, the Master Servicer and the
Trustee may deal with the Depository and the Depository Participants for all
purposes (including the making of distributions) as the authorized
representative of the respective Certificate Owners of such Certificates;

            (c)  registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;

            (d)  the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and
until Definitive Certificates are issued pursuant to Section 5.08, the
Depository will make book-entry transfers among the Depository Participants
and receive and transmit distributions of principal and interest on the
related Certificates to such Depository Participants;

            (e)  the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants;

                                     161
<PAGE>

            (f)  the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants; and

            (g)  to the extent the provisions of this Section conflict with any
other provisions of this Agreement, the provisions of this Section shall
control.

            For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of,
Certificateholders evidencing a specified percentage of the aggregate unpaid
principal amount of any Class of Certificates, such direction or consent may
be given by Certificate Owners (acting through the Depository and the
Depository Participants) owning Book-Entry Certificates evidencing the
requisite percentage of principal amount of such Class of Certificates.

            Section 5.07      Notices to Depository.

            Whenever any notice or other communication is required to be given
to Certificateholders of the Class with respect to which Book-Entry
Certificates have been issued, unless and until Definitive Certificates shall
have been issued to the related Certificate Owners, the Trustee shall give all
such notices and communications to the Depository.

            Section 5.08      Definitive Certificates.

            If, after Book-Entry Certificates have been issued with respect to
any Certificates, (a) the Depositor advises the Trustee that the Depository is
no longer willing or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Trustee or the
Depositor is unable to locate a qualified successor or (b) after the
occurrence and continuation of an Event of Default, Certificate Owners of such
Book-Entry Certificates having not less than 51% of the Voting Rights
evidenced by any Class of Book-Entry Certificates advise the Trustee and the
Depository in writing through the Depository Participants that the
continuation of a book-entry system with respect to Certificates of such Class
through the Depository (or its successor) is no longer in the best interests
of the Certificate Owners of such Class, then the Trustee shall notify all
Certificate Owners of such Certificates, through the Depository, of the
occurrence of any such event and of the availability of Definitive
Certificates to Certificate Owners of such Class requesting the same. The
Depositor shall provide the Trustee with an adequate inventory of Certificates
to facilitate the issuance and transfer of Definitive Certificates. Upon
surrender to the Trustee of any such Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall authenticate and deliver such Definitive Certificates.
Neither the Depositor nor the Trustee shall be liable for any delay in
delivery of such instructions and each may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of such
Definitive Certificates, all references herein to obligations imposed upon or
to be performed by the Depository shall be deemed to be imposed upon and
performed by the Trustee, to the extent applicable with respect to such
Definitive Certificates and the Trustee shall recognize the Holders of such
Definitive Certificates as Certificateholders hereunder.

            Section 5.09      Maintenance of Office or Agency.

            The Trustee will maintain or cause to be maintained at its expense
an office or offices or agency or agencies in New York City where Certificates
may be surrendered for registration of transfer or exchange. The Trustee
initially designates its offices at 101 Barclay Street, New York, New York
10286, Attention: Corporate Trust MBS Administration, as offices for such
purposes. The Trustee will give prompt written notice to the
Certificateholders and the Class AF-5B Insurer of any change in such location
of any such office or agency.

                                  ARTICLE VI.
              THE DEPOSITOR, THE MASTER SERVICER AND THE SELLERS

            Section 6.01      Respective Liabilities of the Depositor, the
                              Master Servicer and the Sellers.

            The Depositor, the Master Servicer and each Seller shall each be
liable in accordance herewith only to the extent of the obligations
specifically and respectively imposed upon and undertaken by them herein.

            Section 6.02      Merger or Consolidation of the Depositor, the
                              Master Servicer or the Sellers.

            The Depositor will keep in full effect its existence, rights and
franchises as a corporation under the laws of the United States or under the
laws of one of the states thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its duties under this Agreement. The Master Servicer will keep in effect its
existence, rights and franchises as a limited partnership under the laws of
the United States or under the laws of one of the states thereof and will
obtain and preserve its qualification or registration to do business as a
foreign partnership in each jurisdiction in which such qualification or
registration is or shall be necessary to protect the validity and
enforceability of this Agreement or any of the Mortgage Loans and to perform
its duties under this Agreement.

            Any Person into which the Depositor, the Master Servicer or any
Seller may be merged or consolidated, or any Person resulting from any merger
or consolidation to which the Depositor, the Master Servicer or any Seller
shall be a party, or any person succeeding to the business of the Depositor,
the Master Servicer or any Seller, shall be the successor of the Depositor,
the Master Servicer or such Seller, as the case may be, hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding; provided that
the successor or surviving Person to the Master Servicer shall be qualified to
service mortgage loans on behalf of Fannie Mae and Freddie Mac.

            Section 6.03      Limitation on Liability of the Depositor, the
                              Sellers, the Master Servicer, the NIM Insurer and
                              Others.

            None of the Depositor, the Sellers, the NIM Insurer or the Master
Servicer or any of the directors, officers, employees or agents of the
Depositor, the Sellers, the NIM Insurer or the Master Servicer shall be under
any liability to the Trustee (except as provided in Section 8.05), the Trust
Fund or the Certificateholders for any action taken or for refraining from the
taking of any action in good faith pursuant to this Agreement, or for errors
in judgment; provided that this provision shall not protect the Depositor, the
Sellers, the Master Servicer or any such Person against any breach of
representations or warranties made by it herein or protect the Depositor, the
Sellers, the Master Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or gross
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder. The Depositor, the Sellers, the NIM Insurer,
the Master Servicer and any director, officer, employee or agent of the
Depositor, the Sellers, the NIM Insurer or the Master Servicer may rely in
good faith on any document of any kind prima facie properly executed and
submitted by any Person respecting any matters arising hereunder. The
Depositor, the Sellers, the NIM Insurer, the Master Servicer and any director,
officer, employee or agent of the Depositor, the Sellers, the NIM Insurer or
the Master Servicer shall be indemnified by the Trust Fund and held harmless
against any loss, liability or expense incurred in connection with any audit,
controversy or judicial proceeding relating to a governmental taxing authority
or any legal action relating to this Agreement or the Certificates, other than
any loss, liability or expense related to any specific Mortgage Loan or
Mortgage Loans (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) and any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. None of the Depositor, the
Sellers, the NIM Insurer or the Master Servicer shall be under any obligation
to appear in, prosecute or defend any legal action that is not incidental to
its respective duties hereunder and that in its opinion may involve it in any
expense or liability; provided that any of the Depositor, the Sellers, the NIM
Insurer or the Master Servicer may, in its discretion undertake any such
action that it may deem necessary or desirable in respect of this Agreement
and the rights and duties of the parties hereto and interests of the Trustee
and the Certificateholders hereunder. In such event, the legal expenses and
costs of such action and any liability resulting therefrom shall be, expenses,
costs and liabilities of the Trust Fund, and the Depositor, the Sellers, the
NIM Insurer and the Master Servicer shall be entitled to be reimbursed
therefor out of the Certificate Account as provided by Section 3.08 hereof.

            Section 6.04      Limitation on Resignation of Master Servicer.

            The Master Servicer shall not resign from the obligations and
duties hereby imposed on it except (i) upon determination that its duties
hereunder are no longer permissible under applicable law or (ii) upon
appointment of a successor servicer that is reasonably acceptable to the
Trustee and the NIM Insurer and the written confirmation from each Rating
Agency (which confirmation shall be furnished to the Depositor, the Trustee
and the NIM Insurer) that such resignation will not cause such Rating Agency
to reduce the then-current rating of the Certificates (such determination to
be made without regard to the Class AF-5B Policy). Any such determination
pursuant to clause (i) of the preceding sentence permitting the

                                     164
<PAGE>

resignation of the Master Servicer shall be evidenced by an Opinion of Counsel
to such effect delivered to the Trustee. No resignation of the Master Servicer
shall become effective until the Trustee shall have assumed the Master
Servicer's responsibilities, duties, liabilities (other than those liabilities
arising prior to the appointment of such successor) and obligations under this
Agreement.

            Section 6.05      Errors and Omissions Insurance; Fidelity Bonds.

            The Master Servicer shall, for so long as it acts as servicer
under this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations
as servicer hereunder, and (b) a fidelity bond in respect of its officers,
employees and agents. Each such policy or policies and bond shall, together,
comply with the requirements from time to time of Fannie Mae and Freddie Mac
for persons performing servicing for mortgage loans purchased by Fannie Mae
and Freddie Mac. In the event that any such policy or bond ceases to be in
effect, the Master Servicer shall use its reasonable best efforts to obtain a
comparable replacement policy or bond from an insurer or issuer, meeting the
requirements set forth above as of the date of such replacement.

            The Master Servicer shall provide the Trustee, the Class AF-5B
Insurer and the NIM Insurer (upon such party's reasonable request) with copies
of any such insurance policies and fidelity bond. The Master Servicer shall be
deemed to have complied with this provision if an Affiliate of the Master
Servicer has such errors and omissions and fidelity bond coverage and, by the
terms of such insurance policy or fidelity bond, the coverage afforded
thereunder extends to the Master Servicer.

                                 ARTICLE VII.
                    DEFAULT; TERMINATION OF MASTER SERVICER

            Section 7.01      Events of Default.

            "Event of Default," wherever used herein, means any one of the
following events:

                 (1)   any failure by the Master Servicer to deposit in the
      Certificate Account or the Distribution Account or remit to the Trustee
      any payment (excluding a payment required to be made under Section 4.01
      hereof) required to be made under the terms of this Agreement, which
      failure shall continue unremedied for five calendar days and, with
      respect to a payment required to be made under Section 4.01(b) or (c)
      hereof, for one Business Day, after the date on which written notice of
      such failure shall have been given to the Master Servicer by the
      Trustee, the NIM Insurer or the Depositor, or to the Trustee, the NIM
      Insurer and the Master Servicer by the Holders of Certificates
      evidencing not less than 25% of the Voting Rights; or

                 (2)   any failure by the Master Servicer to observe or perform
      in any material respect any other of the covenants or agreements on the
      part of the Master Servicer contained in this Agreement or any
      representation or warranty shall prove to be untrue, which failure or
      breach shall continue unremedied for a period of 60 days after the date
      on which written notice of such failure shall have been given to the
      Master Servicer by the Trustee, the NIM Insurer or the Depositor, or to
      the Trustee by the

                                     165
<PAGE>

      Holders of Certificates evidencing not less than 25% of the Voting
      Rights; provided that the sixty-day cure period shall not apply to the
      initial delivery of the Mortgage File for Delay Delivery Mortgage Loans
      nor the failure to repurchase or substitute in lieu thereof; or

                 (3)   a decree or order of a court or agency or supervisory
      authority having jurisdiction in the premises for the appointment of a
      receiver or liquidator in any insolvency, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding-up or liquidation of its affairs, shall have been entered
      against the Master Servicer and such decree or order shall have remained
      in force undischarged or unstayed for a period of 60 consecutive days;
      or

                 (4)   the Master Servicer shall consent to the appointment of
      a receiver or liquidator in any insolvency, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings of or
      relating to the Master Servicer or all or substantially all of the
      property of the Master Servicer; or

                 (5)   the Master Servicer shall admit in writing its inability
      to pay its debts generally as they become due, file a petition to take
      advantage of, or commence a voluntary case under, any applicable
      insolvency or reorganization statute, make an assignment for the benefit
      of its creditors, or voluntarily suspend payment of its obligations; or

                 (6)   the Master Servicer shall fail to reimburse in full the
      Trustee not later than 6:00 p.m. (New York time) on the Business Day
      following the related Distribution Date for any Advance made by the
      Trustee pursuant to Section 4.01(d) together with accrued and unpaid
      interest.

            If an Event of Default shall occur, then, and in each and every
such case, so long as such Event of Default shall not have been remedied, the
Trustee shall, but only at the direction of either the NIM Insurer or the
Holders of Certificates evidencing not less than 25% of the Voting Rights
(subject to the consent of the Class AF-5B Insurer, which consent shall not be
unreasonably withheld), by notice in writing to the Master Servicer (with a
copy to each Rating Agency), terminate all of the rights and obligations of
the Master Servicer under this Agreement and in and to the Mortgage Loans and
the proceeds thereof, other than its rights as a Certificateholder hereunder.
On or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer hereunder, whether with respect to
the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee.
The Trustee shall thereupon make any Advance described in Section 4.01 hereof
subject to Section 3.04 hereof. The Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such
termination shall affect any obligation of the Master Servicer to pay amounts
owed pursuant to Article VIII. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's
responsibilities and rights hereunder,

                                     166
<PAGE>

including, without limitation, the transfer to the Trustee of all cash amounts
which shall at the time be credited to the Certificate Account, or thereafter
be received with respect to the Mortgage Loans. The Trustee shall promptly
notify the Rating Agencies of the occurrence of an Event of Default.

            Notwithstanding any termination of the activities of a Master
Servicer hereunder, such Master Servicer shall be entitled to receive, out of
any late collection of a Scheduled Payment on a Mortgage Loan that was due
prior to the notice terminating such Master Servicer's rights and obligations
as Master Servicer hereunder and received after such notice, that portion
thereof to which such Master Servicer would have been entitled pursuant to
Sections 3.08(a)(i) through (viii), and any other amounts payable to such
Master Servicer hereunder the entitlement to which arose prior to the
termination of its activities hereunder.

            Section 7.02      Trustee to Act; Appointment of Successor.

            On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Master Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Master Servicer by the terms
and provisions hereof and applicable law including the obligation to make
advances pursuant to Section 4.01. As compensation therefor, the Trustee shall
be entitled to all fees, costs and expenses relating to the Mortgage Loans
that the Master Servicer would have been entitled to if the Master Servicer
had continued to act hereunder. Notwithstanding the foregoing, if the Trustee
has become the successor to the Master Servicer in accordance with Section
7.01 hereof, the Trustee may, if it shall be unwilling to so act, or shall, if
it is prohibited by applicable law from making Advances pursuant to Section
4.01 hereof or if it is otherwise unable to so act, (i) appoint any
established mortgage loan servicing institution reasonably acceptable to the
NIM Insurer (as evidenced by the prior written consent of the NIM Insurer), or
(ii) if it is unable for 60 days to appoint a successor servicer reasonably
acceptable to the NIM Insurer, petition a court of competent jurisdiction to
appoint any established mortgage loan servicing institution, the appointment
of which does not adversely affect the then-current rating of the Certificates
(without regard to the Class AF-5B Policy, in the case of the Class AF-5B
Certificates) and the NIM Insurer guaranteed notes (without giving any effect
to any policy or guaranty provided by the NIM Insurer) by each Rating Agency
as the successor to the Master Servicer hereunder in the assumption of all or
any part of the responsibilities, duties or liabilities of the Master Servicer
hereunder. Any successor Master Servicer shall be an institution that is a
Fannie Mae and Freddie Mac approved seller/servicer in good standing, that has
a net worth of at least $15,000,000 and that is willing to service the
Mortgage Loans and executes and delivers to the Depositor and the Trustee an
agreement accepting such delegation and assignment, that contains an
assumption by such Person of the rights, powers, duties, responsibilities,
obligations and liabilities of the Master Servicer (other than liabilities and
indemnities of the Master Servicer under Section 6.03 hereof incurred prior to
termination of the Master Servicer under Section 7.01), with like effect as if
originally named as a party to this Agreement; and provided further that each
Rating Agency acknowledges that its rating of the Certificates in effect
immediately prior to such assignment and delegation will not be qualified or
reduced as a result of such assignment and delegation (without regard to the
Class AF-5B Policy, in the case of the Class AF-5B Certificates). No

                                     167
<PAGE>

appointment of a successor to the Master Servicer hereunder shall be effective
until the Trustee shall have consented thereto, and written notice of such
proposed appointment shall have been provided by the Trustee to each
Certificateholder and the Class AF-5B Insurer. The Trustee shall not resign as
servicer until a successor servicer has been appointed and has accepted such
appointment. Pending appointment of a successor to the Master Servicer
hereunder, the Trustee, unless the Trustee is prohibited by law from so
acting, shall, subject to Section 3.04 hereof, act in such capacity as herein
above provided. In connection with such appointment and assumption, the
Trustee may make such arrangements for the compensation of such successor out
of payments on Mortgage Loans as it and such successor shall agree; provided
that no such compensation shall be in excess of that permitted the Master
Servicer hereunder. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Neither the Trustee nor any other successor servicer shall be
deemed to be in default hereunder by reason of any failure to make, or any
delay in making, any distribution hereunder or any portion thereof or any
failure to perform, or any delay in performing, any duties or responsibilities
hereunder, in either case caused by the failure of the Master Servicer to
deliver or provide, or any delay in delivering or providing, any cash,
information, documents or records to it.

            Any successor to the Master Servicer as servicer shall give notice
to the NIM Insurer and the Mortgagors of such change of servicer and shall,
during the term of its service as servicer maintain in force the policy or
policies that the Master Servicer is required to maintain pursuant to Section
6.05.

            In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent
and warrant that it is a member of MERS in good standing and shall agree to
comply in all material respects with the rules and procedures of MERS in
connection with the servicing of the Mortgage Loans that are registered with
MERS, or (ii) the predecessor Master Servicer shall cooperate with the
successor Master Servicer in causing MERS to execute and deliver an assignment
of Mortgage in recordable form to transfer the Mortgage from MERS to the
Trustee and to execute and deliver such other notices, documents and other
instruments as may be necessary or desirable to effect a transfer of such
Mortgage Loan or servicing of such Mortgage Loan on the MERS(R) System to the
successor Master Servicer. The predecessor Master Servicer shall file or cause
to be filed any such assignment in the appropriate recording office. The
successor Master Servicer shall cause such assignment to be delivered to the
Co-Trustee promptly upon receipt of the original with evidence of recording
thereon or a copy certified by the public recording office in which such
assignment was recorded.

            Section 7.03      Notification to Certificateholders.

            (a)  Upon any termination of or appointment of a successor to the
Master Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, to the Class AF-5B Insurer and to each Rating Agency.

            (b)  Within 60 days after the occurrence of any Event of Default,
the Trustee shall transmit by mail to all Certificateholders notice of each
such Event of Default hereunder known to the Trustee, unless such Event of
Default shall have been cured or waived.

                                 ARTICLE VIII.
                   CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

            Section 8.01      Duties of Trustee.

            The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred and remains
uncured, the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise
as a prudent person would exercise or use under the circumstances in the
conduct of such person's own affairs.

            The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the Trustee (or the Co-Trustee, to the extent provided in this
Agreement) that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they
conform to the requirements of this Agreement, to the extent provided in this
Agreement. If any such instrument is found not to conform to the requirements
of this Agreement in a material manner, the Trustee shall take action as it
deems appropriate to have the instrument corrected.

            No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own grossly negligent action, its own gross
negligent failure to act or its own misconduct, its grossly negligent failure
to perform its obligations in compliance with this Agreement, or any liability
that would be imposed by reason of its willful misfeasance or bad faith;
provided that:

                 (1)   prior to the occurrence of an Event of Default, and
      after the curing of all such Events of Default that may have occurred,
      the duties and obligations of the Trustee shall be determined solely by
      the express provisions of this Agreement, the Trustee shall not be
      liable, individually or as Trustee, except for the performance of such
      duties and obligations as are specifically set forth in this Agreement,
      no implied covenants or obligations shall be read into this Agreement
      against the Trustee and the Trustee may conclusively rely, as to the
      truth of the statements and the correctness of the opinions expressed
      therein, upon any certificates or opinions furnished to the Trustee and
      conforming to the requirements of this Agreement that it reasonably
      believed in good faith to be genuine and to have been duly executed by
      the proper authorities respecting any matters arising hereunder;

                 (2)   the Trustee shall not be liable, individually or as
      Trustee, for an error of judgment made in good faith by a Responsible
      Officer or Responsible Officers of the Trustee, unless the Trustee was
      grossly negligent or acted in bad faith or with willful misfeasance;

                                     169
<PAGE>

                 (3)   the Trustee shall not be liable, individually or as
      Trustee, with respect to any action taken, suffered or omitted to be
      taken by it in good faith in accordance with the direction of the
      Holders of each Class of Certificates evidencing not less than 25% of
      the Voting Rights of such Class relating to the time, method and place
      of conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee under this
      Agreement; and

                 (4)   without in any way limiting the provisions of this
      Section 8.01 or Section 8.02 hereof, the Trustee shall be entitled to
      rely conclusively on the information delivered to it by the Master
      Servicer in a Trustee Advance Notice in determining whether or not it is
      required to make an Advance under Section 4.01(d), shall have no
      responsibility to ascertain or confirm any information contained in any
      Trustee Advance Notice, and shall have no obligation to make any Advance
      under Section 4.01(d) in the absence of a Trustee Advance Notice or
      actual knowledge by a Responsible Officer that (A) a required Advance
      was not made and (B) such required Advance was not a Nonrecoverable
      Advance.

            Section 8.02      Certain Matters Affecting the Trustee.

            (a)  Except as otherwise provided in Section 8.01:

                 (1)   the Trustee may request and rely upon and shall be
      protected in acting or refraining from acting upon any resolution,
      Officer's Certificate, certificate of auditors or any other certificate,
      statement, instrument, opinion, report, notice, request, consent, order,
      appraisal, bond or other paper or document believed by it to be genuine
      and to have been signed or presented by the proper party or parties;

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

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

                 (4)   prior to the occurrence of an Event of Default hereunder
      and after the curing of all Events of Default that may have occurred,
      the Trustee shall not be bound to make any investigation into the facts
      or matters stated in any resolution, certificate, statement, instrument,
      opinion, report, notice, request, consent, order, approval, bond or
      other paper or document, unless requested in writing so to do by the NIM
      Insurer or the Holders of each Class of Certificates evidencing not less
      than 25% of the Voting Rights of such Class; provided, however, that if
      the payment within a reasonable time to the Trustee of the costs,
      expenses or liabilities likely to be incurred by it in the making of
      such investigation is, in the opinion of the Trustee not reasonably
      assured to the Trustee by the NIM Insurer or such Certificateholders,
      the Trustee may require reasonable

                                     170
<PAGE>

      indemnity against such expense, or liability from the NIM Insurer or
      such Certificateholders as a condition to taking any such action;

                 (5)   the Trustee may execute any of the trusts or powers
      hereunder or perform any duties hereunder either directly or by or
      through agents, accountants or attorneys;

                 (6)   the Trustee shall not be required to expend its own
      funds or otherwise incur any financial liability in the performance of
      any of its duties hereunder if it shall have reasonable grounds for
      believing that repayment of such funds or adequate indemnity against
      such liability is not assured to it;

                 (7)   the Trustee shall not be liable, individually or as
      Trustee, for any loss on any investment of funds pursuant to this
      Agreement (other than as issuer of the investment security);

                 (8)   the Trustee shall not be deemed to have knowledge of an
      Event of Default until a Responsible Officer of the Trustee shall have
      received written notice thereof; and

                 (9)   the Trustee shall be under no obligation to exercise any
      of the trusts or powers vested in it by this Agreement or to make any
      investigation of matters arising hereunder or to institute, conduct or
      defend any litigation hereunder or in relation hereto at the request,
      order or direction of the NIM Insurer or any of the Certificateholders,
      pursuant to the provisions of this Agreement, unless the NIM Insurer or
      such Certificateholders, as applicable, shall have offered to the
      Trustee reasonable security or indemnity against the costs, expenses and
      liabilities that may be incurred therein or thereby.

            (b)  All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee
without the possession of any of the Certificates, or the production thereof
at the trial or other proceeding relating thereto, and any such suit, action
or proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

            Section 8.03      Trustee Not Liable for Mortgage Loans.

            The recitals contained herein shall be taken as the statements of
the Depositor or the Master Servicer, as the case may be, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of any
Mortgage Loan or related document or of MERS or the MERS(R) System other than
with respect to the Trustee's execution and authentication of the
Certificates. The Trustee shall not be accountable for the use or application
by the Depositor or the Master Servicer of any funds paid to the Depositor or
the Master Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Certificate Account by the Depositor or the Master
Servicer.

            Section 8.04      Trustee May Own Certificates.

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

            Section 8.05      Master Servicer to Pay Trustee's Fees and
                              Expenses.

            The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement (including, without
limitation: (A) the reasonable compensation and the expenses and disbursements
of its counsel, but only for representation of the Trustee acting in its
capacity as Trustee hereunder and (B) to the extent that the Trustee must
engage persons not regularly in its employ to perform acts or services on
behalf of the Trust Fund, which acts or services are not in the ordinary
course of the duties of a trustee, paying agent or certificate registrar, in
the absence of a breach or default by any party hereto, the reasonable
compensation, expenses and disbursements of such persons, except any such
expense, disbursement or advance as may arise from its negligence, bad faith
or willful misconduct). The Trustee and any director, officer, employee or
agent of the Trustee shall be indemnified by the Master Servicer and held
harmless against any loss, liability or expense (i) incurred in connection
with any legal action relating to this Agreement or the Certificates, or in
connection with the performance of any of the Trustee's duties hereunder,
other than any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of any of the
Trustee's duties hereunder or by reason of reckless disregard of the Trustee's
obligations and duties hereunder or (ii) resulting from any error in any tax
or information return prepared by the Master Servicer. Such indemnity shall
survive the termination of this Agreement or the resignation or removal of the
Trustee hereunder.

            Section 8.06      Eligibility Requirements for Trustee.

            The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and with a
credit rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates (without regard to the Class
AF-5B Policy, in the case of the Class AF-5B Certificates) below the ratings
issued on the Closing Date (or having provided such security from time to time
as is sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation
or national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Sellers and the Master Servicer
and their respective affiliates; provided that such corporation cannot be an

                                     172
<PAGE>

affiliate of the Master Servicer other than the Trustee in its role as
successor to the Master Servicer.

            Section 8.07      Resignation and Removal of Trustee.

            The Trustee may at any time resign and be discharged from the
trusts hereby created by (1) giving written notice of resignation to the
Depositor and the Master Servicer and by mailing notice of resignation by
first class mail, postage prepaid, to the Certificateholders at their
addresses appearing on the Certificate Register and each Rating Agency, not
less than 60 days before the date specified in such notice when, subject to
Section 8.08, such resignation is to take effect, and (2) acceptance of
appointment by a successor trustee in accordance with Section 8.08 and meeting
the qualifications set forth in Section 8.06. If no successor trustee shall
have been so appointed and have accepted appointment within 30 days after the
giving of such notice or resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee.

            If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 hereof and shall fail to resign
after written request thereto by the NIM Insurer or the Depositor, (ii) the
Trustee shall become incapable of acting, or shall be adjudged as bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, or (iii)(A) a tax is imposed with respect to the Trust Fund by
any state in which the Trustee or the Trust Fund is located, (B) the
imposition of such tax would be avoided by the appointment of a different
trustee and (C) the Trustee fails to indemnify the Trust Fund against such
tax, then the Depositor, the NIM Insurer or the Master Servicer may remove the
Trustee and appoint a successor trustee, reasonably acceptable to the NIM
Insurer, by written instrument, in triplicate, one copy of which instrument
shall be delivered to the Trustee, one copy of which shall be delivered to the
Master Servicer and one copy of which shall be delivered to the successor
trustee.

            The Holders evidencing at least 51% of the Voting Rights of each
Class of Certificates may at any time remove the Trustee and appoint a
successor trustee by written instrument or instruments, in triplicate, signed
by such Holders or their attorneys-in-fact duly authorized, one complete set
of which instruments shall be delivered by the successor Trustee to the Master
Servicer one complete set to the Trustee so removed and one complete set to
the successor so appointed. Notice of any removal of the Trustee shall be
given to each Rating Agency by the successor Trustee.

            Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08 hereof.

            Section 8.08      Successor Trustee.

            Any successor trustee appointed as provided in Section 8.07 hereof
shall execute, acknowledge and deliver to the Depositor, its predecessor
trustee and the Master Servicer an instrument accepting such appointment
hereunder and thereupon the resignation or removal of

                                     173
<PAGE>

the predecessor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become fully vested with
all the rights, powers, duties and obligations of its predecessor hereunder,
with the like effect as if originally named as trustee herein. In addition, if
any Corridor Contract is still outstanding, the Person appointed as successor
trustee shall execute, acknowledge and deliver to the predecessor trustee, CHL
and the Master Servicer an instrument accepting the appointment as successor
Corridor Contract Administrator under the Corridor Contract Administration
Agreement.

            No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee
shall be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer and its appointment shall not adversely affect
the then-current ratings of the Certificates (without regard to the Class
AF-5B Policy, in the case of the Class AF-5B Certificates).

            Upon acceptance of appointment by a successor trustee as provided
in this Section 8.08, the Depositor shall mail notice of the succession of
such trustee hereunder to the NIM Insurer and all Holders of Certificates. If
the Depositor fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

            Section 8.09      Merger or Consolidation of Trustee.

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

            Section 8.10      Appointment of Co-Trustee or Separate Trustee.

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

                                     174
<PAGE>

8.06 and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08.

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

                 (1)   All rights, powers, duties and obligations conferred or
      imposed upon the Trustee, except for the obligation of the Trustee under
      this Agreement to advance funds on behalf of the Master Servicer, shall
      be conferred or imposed upon and exercised or performed by the Trustee
      and such separate trustee or co-trustee jointly (it being understood
      that such separate trustee or co-trustee is not authorized to act
      separately without the Trustee joining in such act), except to the
      extent that under any law of any jurisdiction in which any particular
      act or acts are to be performed (whether as Trustee hereunder or as
      successor to the Master Servicer hereunder), the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations (including the holding of
      title to the Trust Fund or any portion thereof in any such jurisdiction)
      shall be exercised and performed singly by such separate trustee or
      co-trustee, but solely at the direction of the Trustee;

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

                 (3)   The Trustee may at any time accept the resignation of or
      remove any separate trustee or co-trustee.

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

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

            Section 8.11      Tax Matters.

            It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC created
pursuant to the Preliminary Statement qualifies as, a "real estate mortgage
investment conduit" as defined in and in accordance with the

                                     175
<PAGE>

REMIC Provisions. In furtherance of such intention, the Trustee covenants and
agrees that it shall act as agent (and the Trustee is hereby appointed to act
as agent) on behalf of the Trust Fund and that in such capacity it shall: (a)
prepare and file, or cause to be prepared and filed, in a timely manner, a
U.S. Real Estate Mortgage Investment Conduit Income Tax Returns (Form 1066 or
any successor form adopted by the Internal Revenue Service) and prepare and
file or cause to be prepared and filed with the Internal Revenue Service and
applicable state or local tax authorities income tax or information returns
for each taxable year with respect to each REMIC created hereunder containing
such information and at the times and in the manner as may be required by the
Code or state or local tax laws, regulations, or rules, and furnish or cause
to be furnished to Certificateholders the schedules, statements or information
at such times and in such manner as may be required thereby; (b) within thirty
days of the Closing Date, furnish or cause to be furnished to the Internal
Revenue Service, on Forms 8811 or as otherwise may be required by the Code,
the name, title, address, and telephone number of the person that the Holders
of the Certificates may contact for tax information relating thereto, together
with such additional information as may be required by such Form, and update
such information at the time or times in the manner required by the Code for
the Trust Fund; (c) make or cause to be made elections, on behalf of each
REMIC created hereunder to be treated as a REMIC on the federal tax return of
each such REMIC for its first taxable year (and, if necessary, under
applicable state law); (d) prepare and forward, or cause to be prepared and
forwarded, to the Certificateholders and to the Internal Revenue Service and,
if necessary, state tax authorities, all information returns and reports as
and when required to be provided to them in accordance with the REMIC
Provisions, including without limitation, the calculation of any original
issue discount using the Prepayment Assumption; (e) provide information
necessary for the computation of tax imposed on the transfer of a Class A-R
Certificate to a Person that is not a Permitted Transferee, or an agent
(including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is
the record holder of an interest (the reasonable cost of computing and
furnishing such information may be charged to the Person liable for such tax);
(f) to the extent that they are under its control conduct the affairs of the
Trust Fund at all times that any Certificates are outstanding so as to
maintain the status of each REMIC created hereunder as a REMIC under the REMIC
Provisions; (g) not knowingly or intentionally take any action or omit to take
any action that would cause the termination of the REMIC status of any REMIC
created hereunder; (h) pay, from the sources specified in the penultimate
paragraph of this Section 8.11, the amount of any federal, state and local
taxes, including prohibited transaction taxes as described below, imposed on
any REMIC created hereunder prior to the termination of the Trust Fund when
and as the same shall be due and payable (but such obligation shall not
prevent the Trustee or any other appropriate Person from contesting any such
tax in appropriate proceedings and shall not prevent the Trustee from
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings); (i) sign or cause to be signed federal, state or local
income tax or information returns; (j) maintain records relating to each REMIC
created hereunder, including but not limited to the income, expenses, assets
and liabilities of each such REMIC, and the fair market value and adjusted
basis of the Trust Fund property determined at such intervals as may be
required by the Code, as may be necessary to prepare the foregoing returns,
schedules, statements or information; and (k) as and when necessary and
appropriate, represent the Trust Fund in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing

settlement agreements with any governmental taxing agency, extend any statute
of limitations relating to any tax item of the Trust Fund, and otherwise act
on behalf of any REMIC created hereunder in relation to any tax matter
involving any such REMIC.

            In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within ten days after the Closing Date all information or data that the
Trustee requests in writing and determines to be relevant for tax purposes to
the valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows
of the Certificates and the Mortgage Loans (and, to the extent not part of the
aforementioned, the information referred to in paragraphs (1), (2), (3) and
(4) of Section 4.05(d)). Thereafter, the Depositor shall provide to the
Trustee promptly upon written request therefor, any such additional
information or data that the Trustee may, from time to time, request in order
to enable the Trustee to perform its duties as set forth herein. The Depositor
hereby indemnifies the Trustee for any losses, liabilities, damages, claims or
expenses of the Trustee arising from any errors or miscalculations of the
Trustee that result from any failure of the Depositor to provide, or to cause
to be provided, accurate information or data to the Trustee on a timely basis.

            In the event that any tax is imposed on "prohibited transactions"
of the Trust Fund as defined in section 860F(a)(2) of the Code, on the "net
income from foreclosure property" of the Trust Fund as defined in section
860G(c) of the Code, on any contribution to the Trust Fund after the startup
day pursuant to section 860G(d) of the Code, or any other tax is imposed,
including, without limitation, any federal, state or local tax or minimum tax
imposed upon the Trust Fund pursuant to sections 23153 and 24872 of the
California Revenue and Taxation Code if not paid as otherwise provided for
herein, such tax shall be paid by (i) the Trustee, if any such other tax
arises out of or results from a breach by the Trustee of any of its
obligations under this Agreement, (ii) (x) the Master Servicer, in the case of
any such minimum tax, and (y) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or (iii) in all other
cases, or in the event that any liable party here fails to honor its
obligations under the preceding clauses (i) or (ii), any such tax will be paid
first with amounts otherwise to be distributed to the Class A-R
Certificateholders, and second with amounts otherwise to be distributed to all
other Certificateholders in the same manner as if such tax were a Realized
Loss that occurred ratably within each Loan Group. Notwithstanding anything to
the contrary contained herein, to the extent that such tax is payable by the
Class A-R Certificates, the Trustee is hereby authorized to retain on any
Distribution Date, from the Holders of the Class A-R Certificates (and, if
necessary, second, from the Holders of the all other Certificates in the
priority specified in the preceding sentence), funds otherwise distributable
to such Holders in an amount sufficient to pay such tax. The Trustee agrees to
promptly notify in writing the party liable for any such tax of the amount
thereof and the due date for the payment thereof.

            The Trustee shall treat the Carryover Reserve Fund as an outside
reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is
owned by the Holders of the Class C Certificates, and that is not an asset of
any REMIC created hereunder. The Trustee shall treat the rights of the Holders
of each Class of Certificates (other than the Class P and Class A-R
Certificates) to receive payments from the Carryover Reserve Fund as rights in
an interest rate corridor contract written by: (i) the Corridor Contract
Counterparty in respect of any Net Rate

                                     177
<PAGE>

Carryover funded by any Corridor Contract and in respect of any residual
payments from such Corridor Contract received by the Class CF or Class CV
Certificates, as the case may be, and (ii) the Holders of the Class CF and
Class CV Certificates in respect of (a) any monies distributed pursuant to
Sections 4.04(e)(20) and 4.04(f)(21) herein, in favor of the other
Certificateholders. Thus, the Class AF-1, Class 1-AV-1 and Class 2-AV
Certificates and the Adjustable Rate Subordinate Certificates, shall be
treated as representing ownership of not only an Master REMIC regular
interest, but also ownership of an interest in an interest rate corridor
contract. For purposes of determining the issue price of the Master REMIC
regular interests, the Trustee shall assume that the Class AF-1 Corridor
Contract, the Class 1-AV Corridor Contract, Class 2-AV Corridor Contract,
Class 3-AV Corridor Contract and Adjustable Rate Subordinate Corridor Contract
have values of $11,000, $200,000, $485,000, $241,000 and $683,000,
respectively. The Trustee shall treat the entitlement to Credit Comeback
Excess Amounts as owned by the Holders of the Class CF Certificates and not as
an asset of, or interest in, any REMIC created hereunder. Further, the Trustee
shall treat any payments of Credit Comeback Excess Amounts to Persons other
than the Holders of the Class CF Certificates as payments made by the Holders
of the Class CF Certificates pursuant to a credit enhancement contract under
Treasury Regulation 1.860G-2(c). The Trustee shall also treat any amount
payable to a Class CF Certificate with respect to an R-3-X Interest as
deposited into the Carryover Reserve Fund.

            Section 8.12      Co-Trustee.

            (a)  The Co-Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the Co-Trustee that are specifically required to be furnished
pursuant to any provision of this Agreement shall examine them to determine
whether they conform to the requirements of this Agreement, to the extent
required by this Agreement. If any such instrument is found not to conform to
the requirements of this Agreement in a material manner, the Co-Trustee shall
take action as it deems appropriate to have the instrument corrected.

            (b)  No provision of this Agreement shall be construed to relieve
the Co-Trustee from liability for its own grossly negligent action, its own
gross negligent failure to act or its own misconduct, its grossly negligent
failure to perform its obligations in compliance with this Agreement, or any
liability that would be imposed by reason of its willful misfeasance or bad
faith; provided that:

                 (1)   the duties and obligations of the Co-Trustee shall be
      determined solely by the express provisions of this Agreement with the
      exception of Section 8.10, the Co-Trustee shall not be liable,
      individually or as Co-Trustee, except for the performance of such duties
      and obligations as are specifically set forth in this Agreement, no
      implied covenants or obligations shall be read into this Agreement
      against the Co-Trustee and the Co-Trustee may conclusively rely, as to
      the truth of the statements and the correctness of the opinions
      expressed therein, upon any certificates or opinions furnished to the
      Co-Trustee and conforming to the requirements of this Agreement that it
      reasonably believed in good faith to be genuine and to have been duly
      executed by the proper authorities respecting any matters arising
      hereunder; and

                                     178
<PAGE>

                 (2)   the Co-Trustee shall not be liable, individually or as
      Co-Trustee, for an error of judgment made in good faith by a Responsible
      Officer or Responsible Officers of the Trustee, unless the Co-Trustee
      was grossly negligent or acted in bad faith or with willful misfeasance.

            (c)  Except as otherwise provided in paragraph (b) above:

                 (1)   the Co-Trustee may request and rely upon and shall be
      protected in acting or refraining from acting upon any resolution,
      Officer's Certificate, certificate of auditors or any other certificate,
      statement, instrument, opinion, report, notice, request, consent, order,
      appraisal, bond or other paper or document believed by it to be genuine
      and to have been signed or presented by the proper party or parties;

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

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

                 (4)   the Co-Trustee shall not be bound to make any
      investigation into the facts or matters stated in any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      consent, order, approval, bond or other paper or document;

                 (5)   the Co-Trustee may execute any of the trusts or powers
      hereunder or perform any duties hereunder either directly or by or
      through agents, accountants or attorneys; and

                 (6)   the Co-Trustee shall not be required to expend its own
      funds or otherwise incur any financial liability in the performance of
      any of its duties hereunder if it shall have reasonable grounds for
      believing that repayment of such funds or adequate indemnity against
      such liability is not assured to it.

            (d)  The recitals contained herein shall be taken as the statements
of the Depositor or the Master Servicer, as the case may be, and the
Co-Trustee assumes no responsibility for their correctness. The Co-Trustee
makes no representations as to the validity or sufficiency of this Agreement
or of any Mortgage Loan or related document or of MERS or the MERS(R) System.
The Co-Trustee shall not be accountable for the use or application by the
Depositor or the Master Servicer of any funds paid to the Depositor or the
Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn
from the Certificate Account by the Depositor or the Master Servicer.

            (e)  The Co-Trustee in its individual or any other capacity may
become the owner or pledgee of Certificates with the same rights as it would
have if it were not the Co-Trustee.

                                     179
<PAGE>

            (f)  The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust) for all services rendered
by it in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Co-Trustee and
(ii) to pay or reimburse the Co-Trustee, upon its request, for all reasonable
expenses, disbursements and advances incurred or made by the Co-Trustee on
behalf of the Trust Fund in accordance with any of the provisions of this
Agreement (including, without limitation: (A) the reasonable compensation and
the expenses and disbursements of its counsel, but only for representation of
the Co-Trustee acting in its capacity as Co-Trustee hereunder and (B) to the
extent that the Co-Trustee must engage persons not regularly in its employ to
perform acts or services on behalf of the Trust Fund, which acts or services
are not in the ordinary course of the duties of a trustee, paying agent or
certificate registrar, in the absence of a breach or default by any party
hereto, the reasonable compensation, expenses and disbursements of such
persons, except any such expense, disbursement or advance as may arise from
its negligence, bad faith or willful misconduct). The Co-Trustee and any
director, officer, employee or agent of the Co-Trustee shall be indemnified by
the Master Servicer and held harmless against any loss, liability or expense
(i) incurred in connection with any legal action relating to this Agreement or
the Certificates, or in connection with the performance of any of the
Co-Trustee's duties hereunder, other than any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance of any of the Co-Trustee's duties hereunder or by reason of
reckless disregard of the Co-Trustee's obligations and duties hereunder and
(ii) resulting from any error in any tax or information return prepared by the
Master Servicer. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Co-Trustee hereunder.

            (g)  The Co-Trustee hereunder shall, at all times, be a corporation
or association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and with a
credit rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates (without regard to the Class
AF-5B Policy, in the case of the Class AF-5B Certificates) below the ratings
issued on the Closing Date (or having provided such security from time to time
as is sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.12 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately
in the manner and with the effect specified in paragraph (h) below. The
corporation or national banking association serving as Co-Trustee may have
normal banking and trust relationships with the Depositor, the Sellers and the
Master Servicer and their respective affiliates; provided that such
corporation cannot be an affiliate of the Master Servicer other than the
Trustee in its role as successor to the Master Servicer.

                                     180
<PAGE>

            (h)  The Co-Trustee may at any time resign and be discharged from
the trusts hereby created by giving 30 days prior written notice of
resignation to the Trustee, the Depositor and the Master Servicer. Upon such
resignation the Trustee (x) may appoint a successor Co-Trustee meeting the
requirements in paragraph (g) above and acceptable to the Master Servicer and
the NIM Insurer (in their sole discretion), so long as such Co-Trustee
executes and delivers to the other parties hereto an instrument agreeing to be
bound by the provisions of this Agreement or (y) may if permitted by the
Master Servicer (in its sole discretion) assume the rights and duties of the
resigning Co-Trustee so long as the Trustee executes and delivers an
instrument to that effect.

            Section 8.13      Access to Records of the Trustee.

            The Trustee and any Co-Trustee shall afford the Sellers, the
Depositor, the Master Servicer, the NIM Insurer, the Class AF-5B Insurer and
each Certificate Owner upon reasonable notice during normal business hours
access to all records maintained by the Trustee or Co-Trustee in respect of
its duties under this Agreement and access to officers of the Trustee
responsible for performing its duties. Upon request, the Trustee or Co-Trustee
shall furnish the Depositor, the Master Servicer, the NIM Insurer, the Class
AF-5B Insurer and any requesting Certificate Owner with its most recent
financial statements. The Trustee shall cooperate fully with the Sellers, the
Master Servicer, the Depositor, the NIM Insurer, the Class AF-5B Insurer and
the Certificate Owner for review and copying any books, documents, or records
requested with respect to the Trustee's and Co-Trustee's respective duties
under this Agreement. The Sellers, the Depositor, the Master Servicer, the
Class AF-5B Insurer and the Certificate Owner shall not have any
responsibility or liability for any action for failure to act by the Trustee
or Co-Trustee and are not obligated to supervise the performance of the
Trustee under this Agreement or otherwise.

            Section 8.14      Suits for Enforcement.

            If an Event of Default or other material default by the Master
Servicer or the Depositor under this Agreement occurs and is continuing, at
the direction of the Certificateholders holding not less than 51% of the
Voting Rights or the NIM Insurer, the Trustee shall proceed to protect and
enforce its rights and the rights of the Certificateholders or the NIM Insurer
under this Agreement by a suit, action, or proceeding in equity or at law or
otherwise, whether for the specific performance of any covenant or agreement
contained in this Agreement or in aid of the execution of any power granted in
this Agreement or for the enforcement of any other legal, equitable, or other
remedy, as the Trustee, being advised by counsel, and subject to the
foregoing, shall deem most effectual to protect and enforce any of the rights
of the Trustee, the NIM Insurer and the Certificateholders.

                                  TERMINATION

            Section 9.01      Termination upon Liquidation or Repurchase of
                              all Mortgage Loans.

            Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Sellers, the Trustee and the Co-Trustee created hereby shall terminate upon
the earlier of (a) the purchase by the Master Servicer or NIM Insurer (the
party exercising such purchase option, the "Terminator") of all of the
Mortgage Loans (and REO Properties) remaining in the Trust Fund at the price
equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage
Loan in the Trust Fund (other than in respect of an REO Property), (ii)
accrued interest thereon at the applicable Mortgage Rate (or, if such
repurchase is effected by the Master Servicer, at the applicable Net Mortgage
Rate, (iii) the appraised value of any REO Property in the Trust Fund (up to
the Stated Principal Balance of the related Mortgage Loan), such appraisal to
be conducted by an appraiser mutually agreed upon by the Terminator and the
Trustee and (iv) plus, if the Terminator is the NIM Insurer, any unreimbursed
Servicing Advances, and the principal portion of any unreimbursed Advances,
made on the Mortgage Loans prior to the exercise of such repurchase and (b)
the later of (i) the maturity or other liquidation (or any Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the
disposition of all REO Property and (ii) the distribution to related
Certificateholders of all amounts required to be distributed to them pursuant
to this Agreement, as applicable. In no event shall the trusts created hereby
continue beyond the earlier of (i) the expiration of 21 years from the death
of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James's, living on the
date hereof and (ii) the Latest Possible Maturity Date. If any such
termination will result in a Deficiency Amount on the Class AF-5B Policy, the
consent of the Class AF-5B Insurer will also be required prior to exercising
such option.

            The right to purchase all Mortgage Loans and REO Properties by the
Terminator pursuant to clause (a) of the immediately preceding paragraph shall
be conditioned upon (1) the Stated Principal Balance of the Mortgage Loans, at
the time of any such repurchase, aggregating ten percent (10%) or less of the
sum of the Cut-off Date Principal Balance of the Initial Mortgage Loans and
the Pre-Funded Amount, (2) unless the NIM Insurer otherwise consents, the
purchase price for such Mortgage Loans and REO Properties shall result in a
final distribution on any NIM Insurer guaranteed notes that is sufficient (x)
to pay such notes in full and (y) to pay any amounts due and payable to the
NIM Insurer pursuant to the indenture related to such notes and (3) unless the
Class AF-5B Insurer otherwise consents, the purchase price for such Mortgage
Loans and REO Properties shall result in a final distribution on the Class
AF-5B Certificates and the Class AF-5B Insurer that is sufficient (x) to pay
such Class AF-5B Certificates in full and (y) to pay any amounts due and
payable to the Class AF-5B Insurer pursuant to the terms hereof.

            The NIM Insurer's right to purchase all Mortgage Loans and REO
Properties shall be further conditioned upon the written consent of the Master
Servicer.

<PAGE>

            Section 9.02      Final Distribution on the Certificates.

            If on any Determination Date, (i) the Master Servicer determines
that there are no Outstanding Mortgage Loans and no other funds or assets in
the Trust Fund other than the funds in the Certificate Account related to such
Loan Group, the Master Servicer shall direct the Trustee to send a final
distribution notice promptly to each related Certificateholder and the Class
AF-5B Insurer or (ii) the Trustee determines that a Class of Certificates
shall be retired after a final distribution on such Class, the Trustee shall
notify the related Certificateholders and the Class AF-5B Insurer within five
(5) Business Days after such Determination Date that the final distribution in
retirement of such Class of Certificates is scheduled to be made on the
immediately following Distribution Date. Any final distribution made pursuant
to the immediately preceding sentence will be made only upon presentation and
surrender of the related Certificates at the Corporate Trust Office of the
Trustee. If the Terminator elects to terminate pursuant to clause (a) of
Section 9.01, at least 20 days prior to the date notice is to be mailed to the
affected Certificateholders, such electing party shall notify the Depositor,
the Class AF-5B Insurer and the Trustee of the date such electing party
intends to terminate and of the applicable repurchase price of the related
Mortgage Loans and REO Properties.

            Notice of any termination, specifying the Distribution Date on
which related Certificateholders may surrender their Certificates for payment
of the final distribution and cancellation, shall be given promptly by the
Trustee by letter to related Certificateholders mailed not earlier than the
10th day and no later than the 15th day of the month immediately preceding the
month of such final distribution. Any such notice shall specify (a) the
Distribution Date upon which final distribution on related Certificates will
be made upon presentation and surrender of such Certificates at the office
therein designated, (b) the amount of such final distribution, (c) the
location of the office or agency at which such presentation and surrender must
be made, and (d) that the Record Date otherwise applicable to such
Distribution Date is not applicable, distributions being made only upon
presentation and surrender of such Certificates at the office therein
specified. The Terminator will give such notice to each Rating Agency at the
time such notice is given to the affected Certificateholders.

            In the event such notice is given, the Master Servicer shall cause
all funds in the Certificate Account to be remitted to the Trustee for deposit
in the Distribution Account on the Business Day prior to the applicable
Distribution Date in an amount equal to the final distribution in respect of
the Certificates. Upon such final deposit and the receipt by the Trustee of a
Request for File Release therefor, the Co-Trustee shall promptly release to
the Master Servicer the Mortgage Files for the Mortgage Loans.

            Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to Certificateholders of each affected Class and
the Class AF-5B Insurer the amounts allocable to such Certificates and the
Class AF-5B Insurer held in the Distribution Account (and, if applicable, the
Carryover Reserve Fund) in the order and priority set forth in Section 4.04
hereof on the final Distribution Date and in proportion to their respective
Percentage Interests. Notwithstanding the reduction of the Certificate
Principal Balance of any Class of Certificates to zero, such Class will be
outstanding hereunder (solely for the purpose of receiving distributions (if
any) to which it may be entitled pursuant to the terms of this Agreement and
not for any other

                                     183
<PAGE>

purpose) until the termination of the respective obligations and
responsibilities of the Depositor, each Seller, the Master Servicer and the
Trustee hereunder in accordance with Article IX.

            In the event that any affected Certificateholders shall not
surrender related Certificates for cancellation within six months after the
date specified in the above mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
related Certificates for cancellation and receive the final distribution with
respect thereto. If within six months after the second notice all the
applicable Certificates shall not have been surrendered for cancellation, the
Trustee may take appropriate steps, or may appoint an agent to take
appropriate steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of the
funds and other assets that remain a part of the Trust Fund. If within one
year after the second notice all related Certificates shall not have been
surrendered for cancellation, the Class AF-5B Insurer, with respect to any
unpaid Class AF-5B Reimbursement Amounts (only to the extent of amounts
received in respect of the Group 1 Mortgage Loans), and then the Class A-R
Certificates shall be entitled to all unclaimed funds and other assets that
remain subject hereto.

            Section 9.03      Additional Termination Requirements.

            (a)  In the event the Terminator exercises its purchase option, the
Trust Fund shall be terminated in accordance with the following additional
requirements, unless the Trustee has been supplied with an Opinion of Counsel,
at the expense of the Terminator, to the effect that the failure of the Trust
Fund to comply with the requirements of this Section 9.03 will not (i) result
in the imposition of taxes on "prohibited transactions" of a REMIC, or (ii)
cause any REMIC created hereunder to fail to qualify as a REMIC at any time
that any Certificates are outstanding:

                 (1)   The Master Servicer shall establish a 90-day liquidation
period and notify the Trustee thereof, which shall in turn specify the first
day of such period in a statement attached to the Trust Fund's final Tax
Return pursuant to Treasury Regulation Section 1.860F-1. The Master Servicer
shall prepare a plan of complete liquidation and shall otherwise satisfy all
the requirements of a qualified liquidation under Section 860F of the Code and
any regulations thereunder, as evidenced by an Opinion of Counsel delivered to
the Trustee and the Depositor obtained at the expense of the Terminator;

                 (2)   During such 90-day liquidation period, and at or prior
to the time of making the final payment on the Certificates, the Master
Servicer as agent of the Trustee shall sell all of the assets of the Trust
Fund to the Terminator for cash; and

                 (3)   At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be
distributed or credited, to the Class A-R Certificateholders all cash on hand
(other than cash retained to meet claims) related to such Class of
Certificates, and the Trust Fund shall terminate at that time.

            (b)  By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to specify the 90-day liquidation period
for the Trust Fund, which authorization shall be binding upon all successor
Certificateholders. The Trustee shall attach a

                                     184
<PAGE>

statement to the final federal income tax return for each of any REMIC created
hereunder stating that pursuant to Treasury Regulation Section 1.860F-1, the
first day of the 90-day liquidation period for each the REMIC was the date on
which the Trustee sold the assets of the Trust Fund to the Terminator.

            (c)  The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1), and together with the Holders of the Class
A-R Certificates agree to take such other action in connection therewith as
may be reasonably requested by the Terminator.

                                  ARTICLE X.

                           MISCELLANEOUS PROVISIONS

            Section 10.01     Amendment.

            This Agreement may be amended from time to time by the Depositor,
the Master Servicer, the Sellers, the Co-Trustee and the Trustee with the
consent of the NIM Insurer, without the consent of any of the
Certificateholders (i) to cure any ambiguity, (ii) to correct or supplement
any provisions herein, (iii) to conform this Agreement to the Prospectus
Supplement or the Prospectus, (iv) to modify, alter, amend, add to or rescind
any of the terms or provisions contained in this Agreement to comply with any
rules or regulations promulgated by the Securities and Exchange Commission
from time to time, or (v) to make such other provisions with respect to
matters or questions arising under this Agreement, as shall not be
inconsistent with any other provisions herein if such action shall not, as
evidenced by an Opinion of Counsel, adversely affect in any material respect
the interests of any Certificateholder; provided that any such amendment shall
be deemed not to adversely affect in any material respect the interests of the
Certificateholders and no such Opinion of Counsel shall be required if the
Person requesting such amendment obtains a letter from each Rating Agency
stating that such amendment would not result in the downgrading or withdrawal
of the respective ratings then assigned to the Certificates (without regard to
the Class AF-5B Policy, in the case of the Class AF-5B Certificates), it being
understood and agreed that any such letter in and of itself will not represent
a determination as to the materiality of any such amendment and will represent
a determination only as to the credit issues affecting any such rating. Any
amendment described above made solely to conform this Agreement to the
Prospectus or the Prospectus Supplement shall be deemed not to adversely
affect in any material respect the interests of the Certificateholders.
Notwithstanding the foregoing, no amendment that significantly changes the
permitted activities of the trust created by this Agreement may be made
without the consent of Certificateholders representing not less than 51% of
the Voting Rights of each Class of Certificates affected by such amendment.
Each party to this Agreement hereby agrees that it will cooperate with each
other party in amending this Agreement pursuant to clause (iv) above.

            The Trustee, the Co-Trustee, the Depositor, the Master Servicer
and the Sellers with the consent of the NIM Insurer may also at any time and
from time to time amend this Agreement, without the consent of the
Certificateholders, to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or appropriate to maintain the qualification
of

                                     185
<PAGE>

the Trust Fund as a REMIC under the Code or to avoid or minimize the risk of
the imposition of any tax on the Trust Fund pursuant to the Code that would be
a claim against the Trust Fund at any time prior to the final redemption of
the Certificates, provided that the Trustee have been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such
opinion but in any case shall not be an expense of the Trustee, to the effect
that such action is necessary or appropriate to maintain such qualification or
to avoid or minimize the risk of the imposition of such a tax.

            This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Sellers, the Co-Trustee and the Trustee
with the consent of the NIM Insurer and the Holders of each Class of
Certificates affected thereby evidencing not less than 51% of the Voting
Rights of such Class for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Holders of Certificates; provided
that no such amendment shall (i) reduce in any manner the amount of, or delay
the timing of, payments required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) adversely affect in any
material respect the interests of the Holders of any Class of Certificates in
a manner other than as described in (i), without the consent of the Holders of
Certificates of such Class evidencing 66% or more of the Voting Rights of such
Class, (iii) reduce the aforesaid percentages of Certificates the Holders of
which are required to consent to any such amendment without the consent of the
Holders of all such Certificates then outstanding, or (iv) adversely affect in
any material respect the rights and interests of the Class AF-5B Insurer in
any of the provisions of this Agreement without its consent, which consent
shall not be unreasonably withheld: (I) the definitions of "Class AF-5B
Premium" and "Reimbursement Amount" in Article I, (II) the priority of
payments to the Class AF-5B Insurer pursuant to Sections 4.04(a), (b) and (d)
and (III) Sections 4.06, 10.01, and 10.12.

            Notwithstanding any contrary provision of this Agreement, the
Trustee and the NIM Insurer shall not consent to any amendment to this
Agreement unless each shall have first received an Opinion of Counsel
satisfactory to the Trustee and the NIM Insurer, which opinion shall be an
expense of the party requesting such amendment but in any case shall not be an
expense of the Trustee or the NIM Insurer, to the effect that such amendment
will not cause the imposition of any tax on the Trust Fund or the
Certificateholders or cause any REMIC formed hereunder to fail to qualify as a
REMIC at any time that any Certificates are outstanding.

            Promptly after the execution of any amendment to this Agreement,
the Trustee shall furnish written notification of the substance of such
amendment to the Class AF-5B Insurer and, if the amendment required the
consent of Certificateholders, to each Certificateholder and each Rating
Agency.

            It shall not be necessary for the consent of Certificateholders
under this Section to approve the particular form of any proposed amendment,
but it shall be sufficient if such consent shall approve the substance
thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject
to such reasonable regulations as the Trustee may prescribe.

                                     186
<PAGE>

            Nothing in this Agreement shall require the Trustee to enter into
an amendment without receiving an Opinion of Counsel, reasonably satisfactory
to the Trustee and the NIM Insurer that (i) such amendment is permitted and is
not prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any
Certificateholder or (B) the conclusion set forth in the immediately preceding
clause (A) is not required to be reached pursuant to this Section 10.01.

            Section 10.02     Recordation of Agreement; Counterparts.

            This Agreement is subject to recordation in all appropriate public
offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages
are situated, and in any other appropriate public recording office or
elsewhere, such recordation to be effected by the Master Servicer at its
expense.

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

            Section 10.03     Governing Law.

            THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE
AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED
IN ACCORDANCE WITH SUCH LAWS.

            Section 10.04     Intention of Parties.

            It is the express intent of the parties hereto that the conveyance
of the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance
policies and any modifications, extensions and/or assumption agreements and
private mortgage insurance policies relating to the Mortgage Loans by the
Depositor to the Trustee be, and be construed as, an absolute sale thereof to
the Trustee. It is, further, not the intention of the parties that such
conveyance be deemed a pledge thereof by the Depositor to the Trustee.
However, in the event that, notwithstanding the intent of the parties, such
assets are held to be the property of the Depositor, or if for any other
reason this Agreement or any Subsequent Transfer Agreement is held or deemed
to create a security interest in such assets, then (i) this Agreement shall be
deemed to be a security agreement (within the meaning of the Uniform
Commercial Code of the State of New York) with respect to all such assets and
security interests and (ii) the conveyance provided for in this Agreement and
any Subsequent Transfer Agreement shall be deemed to be an assignment and a
grant pursuant to the terms of this Agreement by the Depositor to the Trustee,
for the benefit of the Certificateholders, of a security interest in all of
the assets that constitute the Trust Fund, whether now owned or hereafter
acquired.

                                     187
<PAGE>

            The Depositor for the benefit of the Certificateholders and the
NIM Insurer shall, to the extent consistent with this Agreement, take such
actions as may be necessary to ensure that, if this Agreement were deemed to
create a security interest in the assets of the Trust Fund, such security
interest would be deemed to be a perfected security interest of first priority
under applicable law and will be maintained as such throughout the term of the
Agreement. The Depositor shall arrange for filing any Uniform Commercial Code
continuation statements in connection with any security interest granted or
assigned to the Trustee for the benefit of the Certificateholders.

            Section 10.05     Notices.

            (a)  The Trustee shall use its best efforts to promptly provide
notice to each Rating Agency with respect to each of the following of which it
has actual knowledge:

                 (1)   Any material change or amendment to this Agreement;

                 (2)   The occurrence of any Event of Default that has not been
      cured;

                 (3)   The resignation or termination of the Master Servicer or
      the Trustee and the appointment of any successor;

      pursuant to Sections 2.02, 2.03, 2.04 and 3.12; and

                 (5)   The final payment to Certificateholders.

            (b)  In addition, the Trustee shall promptly furnish to each Rating
Agency copies of the following:

      4.05;

            Section 10.06     Severability of Provisions.

            If any one or more of the covenants, agreements, provisions or
terms of this Agreement shall be for any reason whatsoever held invalid, then
such covenants, agreements, provisions or terms shall be deemed severable from
the remaining covenants, agreements, provisions or terms of this Agreement and
shall in no way affect the validity or enforceability of the other provisions
of this Agreement or of the Certificates or the rights of the Holders thereof.

            Section 10.07     Assignment.

            Notwithstanding anything to the contrary contained herein, except
as provided pursuant to Section 6.02, this Agreement may not be assigned by
the Master Servicer without the prior written consent of the Trustee and the
Depositor.

            Section 10.08     Limitation on Rights of Certificateholders.

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

            No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and
management of the Trust Fund, or the

                                     189
<PAGE>

obligations of the parties hereto, nor shall anything herein set forth or
contained in the terms of the Certificates be construed so as to constitute
the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any
third party by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

            No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this
Agreement, unless such Holder previously shall have given to the Trustee a
written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, the Holders of Certificates evidencing not less than
25% of the Voting Rights shall also have made written request to the Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as
it may require against the costs, expenses, and liabilities to be incurred
therein or thereby, and the Trustee, for 60 days after its receipt of such
notice, request and offer of indemnity shall have neglected or refused to
institute any such action, suit or proceeding; it being understood and
intended, and being expressly covenanted by each Certificateholder with every
other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatever by virtue or by
availing itself or themselves of any provisions of this Agreement to affect,
disturb or prejudice the rights of the Holders of any other of the
Certificates, or to obtain or seek to obtain priority over or preference to
any other such Holder or to enforce any right under this Agreement, except in
the manner herein provided and for the common benefit of all
Certificateholders. For the protection and enforcement of the provisions of
this Section 10.08, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

            Section 10.09     Inspection and Audit Rights.

            The Master Servicer agrees that, on reasonable prior notice, it
will permit any representative of the Depositor, any Seller, the NIM Insurer
or the Trustee during the Master Servicer's normal business hours, to examine
all the books of account, records, reports and other papers of the Master
Servicer relating to the Mortgage Loans, to make copies and extracts
therefrom, to cause such books to be audited by independent certified public
accountants selected by the Depositor, a Seller, the NIM Insurer or the
Trustee and to discuss its affairs, finances and accounts relating to the
Mortgage Loans with its officers, employees and independent public accountants
(and by this provision the Master Servicer hereby authorizes such accountants
to discuss with such representative such affairs, finances and accounts), all
at such reasonable times and as often as may be reasonably requested. Any
out-of-pocket expense incident to the exercise by the Depositor, any Seller,
the NIM Insurer or the Trustee of any right under this Section 10.09 shall be
borne by the party requesting such inspection; all other such expenses shall
be borne by the Master Servicer.

            Section 10.10     Certificates Nonassessable and Fully Paid.

            It is the intention of the Depositor that Certificateholders shall
not be personally liable for obligations of the Trust Fund, that the interests
in the Trust Fund represented by the Certificates shall be nonassessable for
any reason whatsoever, and that the Certificates, upon due

                                     190
<PAGE>

authentication thereof by the Trustee pursuant to this Agreement, are and
shall be deemed fully paid.

            Section 10.11     Rights of NIM Insurer.

            (a)  The rights of the NIM Insurer under this Agreement shall exist
only so long as either:

                 (1)   the notes certain payments on which are guaranteed by
      the NIM Insurer remain outstanding or

                 (2)   the NIM Insurer is owed amounts paid by it with respect
      to that guaranty.

            (b)  The rights of the NIM Insurer under this Agreement are
exercisable by the NIM Insurer only so long as no default by the NIM Insurer
under its guaranty of certain payments under notes backed or secured by the
Class C or Class P Certificates has occurred and is continuing. If the NIM
Insurer is the subject of any insolvency proceeding, the rights of the NIM
Insurer under this Agreement will be exercisable by the NIM Insurer only so
long as:

                 (1)   the obligations of the NIM Insurer under its guaranty of
      notes backed or secured by the Class C or Class P Certificates have not
      been disavowed and

                 (2)   CHL and the Trustee have received reasonable assurances
      that the NIM Insurer will be able to satisfy its obligations under its
      guaranty of notes or secured by the Class C or Class P Certificates.

            (c)  The NIM Insurer is a third party beneficiary of this Agreement
to the same extent as if it were a party to this Agreement and may enforce any
of those rights under this Agreement.

            (d)  A copy of any documents of any nature required by this
Agreement to be delivered by the Trustee, or to the Trustee or the Rating
Agencies, shall in each case at the same time also be delivered to the NIM
Insurer. Any notices required to be given by the Trustee, or to the Trustee or
the Rating Agencies, shall in each case at the same time also be given to the
NIM Insurer. If the Trustee receives a notice or document that is required
hereunder to be delivered to the NIM Insurer, and if such notice or document
does not indicate that a copy thereof has been previously sent to the NIM
Insurer, the Trustee shall send the NIM Insurer a copy of such notice or
document. If such document is an Opinion of Counsel, the NIM Insurer shall be
an addressee thereof or such Opinion of Counsel shall contain language
permitting the NIM Insurer to rely thereon as if the NIM Insurer were an
addressee thereof.

            (e)  Anything in this Agreement that is conditioned on not
resulting in the downgrading or withdrawal of the ratings then assigned to the
Certificates by the Rating Agencies shall also be conditioned on not resulting
in the downgrading or withdrawal of the ratings then assigned by the Rating
Agencies to the notes backed or secured by the Class C or Class P Certificates
(without giving effect to any policy or guaranty provided by the NIM Insurer).

                             )      ss.:
COUNTY OF                    )

            The undersigned, being first duly sworn, deposes and says as
follows:

            1. The undersigned is an officer of _______________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, dated
as of March 1, 2005 (the "Agreement"), by and among CWABS, Inc., as depositor
(the "Depositor"), Countrywide Home Loans, Inc., as a Seller, Park Monaco
Inc., as a Seller, Park Sienna LLC, as a Seller, Countrywide Home Loans
Servicing LP, as Master Servicer, The Bank of New York Trust Company, N.A., as
Co-Trustee and The Bank of New York, as Trustee. Capitalized terms used, but
not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to
such terms in the Agreement. The Transferee has authorized the undersigned to
make this affidavit on behalf of the Transferee.

            2. The Transferee is not an employee benefit plan that is subject
to Title I of ERISA or to section 4975 of the Internal Revenue Code of 1986,
nor is it acting on behalf of or with plan assets of any such plan. The
Transferee is, as of the date hereof, and will be, as of the date of the
Transfer, a Permitted Transferee. The Transferee will endeavor to remain a
Permitted Transferee for so long as it retains its Ownership Interest in the
Certificate. The Transferee is acquiring its Ownership Interest in the
Certificate for its own account.

            3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability
for the tax if the subsequent Transferee furnished to such Person an affidavit
that such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

            4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the
pass-through entity does not have actual knowledge that such affidavit is
false. (For this purpose, a "pass-through entity" includes a regulated
investment company, a real estate investment trust or common trust fund, a
partnership, trust or estate, and certain cooperatives and, except as may be
provided in Treasury Regulations, persons holding interests in pass-through
entities as a nominee for another Person.)

<PAGE>

            5. The Transferee has reviewed the provisions of Section 5.02(c)
of the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by
and to abide by the provisions of Section 5.02(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

            6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in
the Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit J-1 to the Agreement (a "Transferor Certificate") to
the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

            7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect
to the Class A-R Certificates.

            8. The Transferee's taxpayer identification number is _____.

            9. The Transferee is a U.S. Person as defined in Code section
7701(a)(30).

            10. The Transferee is aware that the Class A-R Certificates may be
"noneconomic residual interests" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with
respect to the income on such residual interest, unless no significant purpose
of the transfer was to impede the assessment or collection of tax. In
addition, as the Holder of a noneconomic residual interest, the Transferee may
incur tax liabilities in excess of any cash flows generated by the interest
and the Transferee hereby represents that it intends to pay taxes associated
with holding the residual interest as they become due.

            11. The Transferee has provided financial statements or other
financial information requested by the Transferor in connection with the
transfer of the Class A-R Certificates to permit the Transferor to assess the
financial capability of the Transferee to pay such taxes.

                                    * * *

                              Certain Definitions

            "Ownership Interest": As to any Certificate, any ownership
interest in such Certificate, including any interest in such Certificate as
the Holder thereof and any other interest therein, whether direct or indirect,
legal or beneficial.

            "Permitted Transferee": Any person other than (i) the United
States, any State or political subdivision thereof, or any agency or
instrumentality of any of the foregoing, (ii) a foreign government,
International Organization or any agency or instrumentality of either of the
foregoing, (iii) an organization (except certain farmers' cooperatives
described in section 521 of the Code) that is exempt from tax imposed by
Chapter 1 of the Code (including the tax imposed by section 511 of the Code on
unrelated business taxable income) on any excess inclusions (as defined in
section 860E(c)(1) of the Code) with respect to any Class A-R Certificate,
(iv) rural electric and telephone cooperatives described in section
1381(a)(2)(C) of the Code, (v) an "electing large partnership" as defined in
section 775 of the Code, (vi) a Person that is not a citizen or resident of
the United States, a corporation, partnership, or other entity (treated as a
corporation or a partnership for federal income tax purposes) created or
organized in or under the laws of the United States, any state thereof or the
District of Columbia, or an estate whose income from sources without the
United States is includible in gross income for United States federal income
tax purposes regardless of its connection with the conduct of a trade or
business within the United States, or a trust if a court within the United
States is able to exercise primary supervision over the administration of the
trust and one or more United States persons have authority to control all
substantial decisions of the trustor unless such Person has furnished the
transferor and the Trustee with a duly completed Internal Revenue Service Form
W-8ECI, and (vii) any other Person so designated by the Trustee based upon an
Opinion of Counsel that the Transfer of an Ownership Interest in a Class A-R

terms "United States," "State" and "International Organization" shall have the
meanings set forth in section 7701 of the Code or successor provisions. A
corporation will not be treated as an instrumentality of the United States or
of any State or political subdivision thereof for these purposes if all of its
activities are subject to tax and, with the exception of the Federal Home Loan
Mortgage Corporation, a majority of its board of directors is not selected by
such government unit.

            "Person": Any individual, corporation, limited liability company,
partnership, joint venture, bank, joint stock company, trust (including any
beneficiary thereof), unincorporated organization or government or any agency
or political subdivision thereof.

            "Transfer": Any direct or indirect transfer or sale of any

                       Section 5.02(c) of the Agreement

            (c) Each Person who has or who acquires any Ownership Interest in
a Class A-R Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the following
provisions, and the rights of each Person acquiring any Ownership Interest in
a Class A-R Certificate are expressly subject to the following provisions:

            (i) Each Person holding or acquiring any Ownership Interest in a
      Class A-R Certificate shall be a Permitted Transferee and shall promptly
      notify the Trustee of any change or impending change in its status as a
      Permitted Transferee.

            (ii) Except in connection with (i) the registration of the Tax
      Matters Person Certificate in the name of the Trustee or (ii) any
      registration in the name of, or transfer of a Class A-R Certificate to,
      an affiliate of the Depositor (either directly or through a nominee) on
      or about the Closing Date, no Ownership Interest in a Class A-R
      Certificate may be registered on the Closing Date or thereafter
      transferred, and the Trustee shall not register the Transfer of any
      Class A-R Certificate unless, the Trustee shall have been furnished with
      an affidavit (a "Transfer Affidavit") of the initial owner or the
      proposed transferee in the form attached hereto as Exhibit I-1 or
      Exhibit I-2, respectively.

            (iii) Each Person holding or acquiring any Ownership Interest in a
      Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit
      from any other Person to whom such Person attempts to Transfer its
      Ownership Interest in a Class A-R Certificate, (B) to obtain a Transfer
      Affidavit from any Person for whom such Person is acting as nominee,
      trustee or agent in connection with any Transfer of a Class A-R
      Certificate and (C) not to Transfer its Ownership Interest in a Class
      A-R Certificate, or to cause the Transfer of an Ownership Interest in a
      Class A-R Certificate to any other Person, if it has actual knowledge
      that such Person is not a Permitted Transferee.

            (iv) Any attempted or purported Transfer of any Ownership Interest
      in a Class A-R Certificate in violation of the provisions of this
      Section 5.02(c) shall be absolutely null and void and shall vest no
      rights in the purported Transferee. If any purported transferee shall
      become a Holder of a Class A-R Certificate in violation of the
      provisions of this Section 5.02(c), then the last preceding Permitted
      Transferee shall be restored to all rights as Holder thereof retroactive
      to the date of registration of Transfer of such Class A-R Certificate.
      The Trustee shall be under no liability to any Person for any
      registration of Transfer of a Class A-R Certificate that is in fact not
      permitted by Section 5.02(b) and this Section 5.02(c) or for making any
      payments due on such Certificate to the Holder thereof or taking any
      other action with respect to such Holder under the provisions of this
      Agreement so long as the Transfer was registered after receipt of the
      related Transfer Affidavit and Transferor Certificate. The Trustee shall
      be entitled but not obligated to recover from any Holder of a Class A-R
      Certificate that was in fact not a Permitted Transferee at the time it
      became a Holder or, at such subsequent time as it became other than a
      Permitted Transferee, all payments made on such Class A-R Certificate at
      and after either such time. Any such payments so recovered by the
      Trustee

                                    I-1-5
<PAGE>

      shall be paid and delivered by the Trustee to the last preceding
      Permitted Transferee of such Certificate.

            (v) The Master Servicer shall use its best efforts to make
      available, upon receipt of written request from the Trustee, all
      information necessary to compute any tax imposed under section 860E(e)
      of the Code as a result of a Transfer of an Ownership Interest in a
      Class A-R Certificate to any Holder who is not a Permitted Transferee.

            The restrictions on Transfers of a Class A-R Certificate set forth
in this section 5.02(c) shall cease to apply (and the applicable portions of
the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Sellers
or the Master Servicer to the effect that the elimination of such restrictions
will not cause any constituent REMIC of any REMIC formed hereunder to fail to
qualify as a REMIC at any time that the Certificates are outstanding or result
in the imposition of any tax on the Trust Fund, a Certificateholder or another
Person. Each Person holding or acquiring any ownership Interest in a Class A-R
Certificate hereby consents to any amendment of this Agreement that, based on
an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Class
A-R Certificate is not transferred, directly or indirectly, to a Person that
is not a Permitted Transferee and (b) to provide for a means to compel the
Transfer of a Class A-R Certificate that is held by a Person that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

      For purposes of determining the aggregate amount of securities owned
         and/or invested on a discretionary basis by the Buyer, the Buyer used
         the cost of such securities to the Buyer and did not include any of
         the securities referred to in the preceding paragraph, except (i)
         where the Buyer reports its securities holdings in its financial
         statements on the basis of their market value, and (ii) no current
         information with respect to the cost of those securities has been
         published. If clause (ii) in the preceding sentence applies, the
         securities may be valued at market. Further, in determining such
         aggregate amount, the Buyer may have included securities owned by
         subsidiaries of the Buyer, but only if such subsidiaries are
         consolidated with the Buyer in its financial statements prepared in
         accordance with generally accepted accounting principles and if the
         investments of such subsidiaries are managed under the Buyer's
         direction. However, such securities were not included if the Buyer is
         a majority-owned, consolidated subsidiary of another enterprise and
         the Buyer is not itself a reporting company under the Securities
         Exchange Act of 1934, as amended.

      The Buyer acknowledges that it is familiar with Rule 144A and
         understands that the seller to it and other parties related to the
         Certificates are relying and will continue to rely on the statements
         made herein because one or more sales to the Buyer may be in reliance
         on Rule 144A.

      Until the date of purchase of the Rule 144A Securities, the Buyer will
         notify each of the parties to which this certification is made of any
         changes in the information and conclusions herein. Until such notice
         is given, the Buyer's purchase of the Certificates will constitute a
         reaffirmation of this certification as of the date of such purchase.
         In addition, if the Buyer is a bank or savings and loan is provided
         above, the Buyer agrees that it will furnish to such parties updated
         annual financial statements promptly after they become available.

           QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

          [For Transferees That are Registered Investment Companies]

The undersigned (the "Buyer") hereby certifies as follows to the parties
listed in the Rule 144A Transferee Certificate to which this certification
relates with respect to the Certificates described therein:

            1. As indicated below, the undersigned is the President, Chief
Financial Officer or Senior Vice President of the Buyer or, if the Buyer is a
"qualified institutional buyer" as that term is defined in Rule 144A under the
Securities Act of 1933, as amended ("Rule 144A") because Buyer is part of a
Family of Investment Companies (as defined below), is such an officer of the
Adviser.

      In connection with purchases by Buyer, the Buyer is a "qualified
         institutional buyer" as defined in SEC Rule 144A because (i) the
         Buyer is an investment company registered under the Investment
         Company Act of 1940, as amended and (ii) as marked below, the Buyer
         alone, or the Buyer's Family of Investment Companies, owned at least
         $100,000,000 in securities (other than the excluded securities
         referred to below) as of the end of the Buyer's most recent fiscal
         year. For purposes of determining the amount of securities owned by
         the Buyer or the Buyer's Family of Investment Companies, the cost of
         such securities was used, except (i) where the Buyer or the Buyer's
         Family of Investment Companies reports its securities holdings in its
         financial statements on the basis of their market value, and (ii) no
         current information with respect to the cost of those securities has
         been published. If clause (ii) in the preceding sentence applies, the
         securities may be valued at market.

      ___  The Buyer owned $ in securities (other than the excluded securities
           referred to below) as of the end of the Buyer's most recent fiscal
           year (such amount being calculated in accordance with Rule 144A).

      ___  The Buyer is part of a Family of Investment Companies which owned
           in the aggregate $ in securities (other than the excluded
           securities referred to below) as of the end of the Buyer's most
           recent fiscal year (such amount being calculated in accordance with
           Rule 144A).

   The term "Family of Investment Companies" as used herein means two or more
      registered investment companies (or series thereof) that have the same
      investment adviser or investment advisers that are affiliated (by virtue
      of being majority owned subsidiaries of the same parent or because one
      investment adviser is a majority owned subsidiary of the other).

   The term "securities" as used herein does not include (i) securities of
      issuers that are affiliated with the Buyer or are part of the Buyer's
      Family of Investment Companies, (ii) securities issued or guaranteed by
      the U.S. or any instrumentality thereof, (iii) bank deposit notes and
      certificates of deposit, (iv) loan participations, (v) repurchase

                                     L-6
<PAGE>

      agreements, (vi) securities owned but subject to a repurchase agreement
      and (vii) currency, interest rate and commodity swaps.

   The Buyer is familiar with Rule 144A and under-stands that the parties
      listed in the Rule 144A Transferee Certificate to which this
      certification relates are relying and will continue to rely on the
      statements made herein because one or more sales to the Buyer will be in
      reliance on Rule 144A. In addition, the Buyer will only purchase for the
      Buyer's own account.

   Until the date of purchase of the Certificates, the undersigned will notify
      the parties listed in the Rule 144A Transferee Certificate to which this
      certification relates of any changes in the information and conclusions
      herein. Until such notice is given, the Buyer's purchase of the
      Certificates will constitute a reaffirmation of this certification by
      the undersigned as of the date of such purchase.

                                                     hereof.

Ambac Assurance Corporation (Ambac), a Wisconsin stock insurance corporation,
in consideration of the payment of the premium and subject to the terms of
this Policy, hereby agrees unconditionally and irrevocably to pay to the
Trustee for the benefit of the Holders of the Insured Obligations, that
portion of the Insured Amounts which shall become Due for Payment but shall be
unpaid by reason of Nonpayment.

Ambac will make such payments to the Trustee from its own funds on the later
of (a) one (1) Business Day following notification to Ambac of Nonpayment or
(b) the Business Day on which the Insured Amounts are Due for Payment. Such
payments of principal or interest shall be made only upon presentation of an
instrument of assignment in form and substance satisfactory to Ambac,
transferring to Ambac all rights under such Insured Obligations to receive the
principal of and interest on the Insured Obligation. Ambac shall be subrogated
to all the Holders' rights to payment on the Insured Obligations to the extent
of the insurance disbursements so made. Once payments of the Insured Amounts
have been made to the Trustee, Ambac shall have no further obligation
hereunder in respect of such Insured Amounts.

In the event the Trustee for the Insured Obligations has notice that any
payment of principal or interest on an Insured Obligation which has become Due
for Payment and which is made to a Holder by or on behalf of the Trustee has
been deemed a preferential transfer and theretofore recovered from its Holder
pursuant to the United States Bankruptcy Code in accordance with a final,
nonappealable order of a court of competent jurisdiction, such Holder will be
entitled to payment from Ambac to the extent of such recovery if sufficient
funds are not otherwise available.

This Policy is  noncancelable  by Ambac for any reason,  including  failure to
receive  payment of any premium due  hereunder.  The premium on this Policy is
not refundable for any reason. This

<PAGE>

Policy does not insure against loss of any prepayment or other acceleration
payment which at any time may become due in respect of any Insured Obligation,
other than at the sole option of Ambac, nor against any risk other than
Nonpayment, including failure of the Trustee to make any payment due Holders
of Insured Amounts.

To the fullest extent permitted by applicable law, Ambac hereby waives and
agrees not to assert any and all rights and defenses, to the extent such
rights and defenses may be available to Ambac, to avoid payment of its
obligations under this Policy in accordance with the express provisions
hereof.

Any capitalized terms not defined herein shall have the meaning given such
terms in the endorsement attached hereto or in the Agreement.

In witness whereof, Ambac has caused this Policy to be affixed with its
corporate seal and to be signed by its duly authorized officers in facsimile
to become effective as their original signatures and binding upon Ambac by
virtue of the countersignature of its duly authorized representative.

full payment of all Reimbursement Amounts owed to it hereunder or under the
Agreement.

Interest Shortfalls, any shortfalls resulting from the application of the
Relief Act or similar state or local law or any Net Rate Carryover allocable
to the Class AF-5B Certificates, nor does the Policy guarantee to

<PAGE>

the Holders of the Class AF-5B Certificates any particular rate of principal
payment. In addition, the Policy does not cover shortfalls, if any,
attributable to the liability of the Trust, any REMIC or the Trustee for
withholding taxes, if any, (including interest and penalties in respect of any
liability for withholding taxes) nor any risk other than Nonpayment, including
the failure of the Trustee or Paying Agent to make any payment required under
the Agreement to the Holders of the Class AF-5B Certificates.

      The terms and provisions of the Agreement constitute the instrument of
assignment referred to in the second paragraph of the face of this Policy.

      A premium will be payable on this Policy on each Distribution Date as
provided in Section 4.04 of the Agreement, beginning with the First
Distribution Date, in an amount equal to the Class AF-5B Premium.

      THE INSURANCE PROVIDED BY THE POLICY IS NOT COVERED BY THE
PROPERTY/CASUALTY INSURANCE SECURITY FUND SPECIFIED IN ARTICLE 76 OF THE NEW
YORK INSURANCE LAW.

      Nothing herein contained shall be held to vary, alter, waive or extend
any of the terms, conditions, provisions, agreements or limitations of the
above mentioned Policy other than as above stated.

      To the extent the provisions of this endorsement conflict with the
provisions in the above-mentioned Policy, the provisions of this endorsement
shall govern.

      The Policy and the obligations of the Class AF-5B Certificate Insurer
thereunder will terminate without any action on the part of the Class AF-5B
Certificate Insurer or any other person on the date following the later to
occur of (i) the date that is one year and one day following the date on which
all amounts required to be paid on the Class AF-5B Certificates have been paid
in full and (ii) if any proceeding referenced in the first full paragraph
which begins on page 4 of this Policy Endorsement has been commenced on or
prior to the date specified in clause (i) of this paragraph, the 30th day
after the entry of a final, non-appealable order in resolution or settlement
of such proceeding. Upon termination of this Policy, the Trustee shall deliver
the original of the Policy to the Class AF-5B Certificate Insurer.

      No person other than the Trustee shall be entitled to present the
Notice.

      No waiver of any rights or powers of the Class AF-5B Certificate
Insurer, the Holders or the Trustee or consent by any of them shall be valid
unless signed by an authorized officer or agent thereof.

      This Policy is issued under and pursuant to, and shall be construed in
accordance with, the laws of the State of New York, without giving effect to
the conflict of laws principles thereof.

      The Class AF-5B Certificate Insurer's obligations under the Policy will
be discharged to the extent that funds are received by the Trustee for payment
to the Holders of the Class AF-5B Certificates whether or not those funds are
properly paid by the Trustee. Payments of Insured

<PAGE>

Amounts will be made only at the time set forth herein, and no accelerated
payments of Insured Amounts will be made regardless of any acceleration of the
Class AF-5B Certificates, unless the acceleration is at the sole option of the
Class AF-5B Certificate Insurer.

      IN WITNESS WHEREOF, Ambac Assurance Corporation has caused this
endorsement to the Policy to be signed by its duly authorized officers.

     POOLING AND SERVICING AGREEMENT, dated as of March 1, 2005, by and among
CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as a seller ("CHL" or a
"9eller"), PARK MONACO INC., a Delaware corporation, as a seller ("Park Monaco"
or a "Seller"), PARK SIENNA LLC, a Delaware limited liability company, as a
seller ("Park Sienna" or a "Seller", and together with CHL and Park Monaco, the
"Sellers"), COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited partnership,
as master servicer (the "Master Servicer"), THE BANK OF NEW YORK, a New York
banking corporation, as trustee (the "Trustee"), and THE BANK OF NEW YORK TRUST
COMPANY, N.A., a national banking association, as co-trustee (the
"Co-Trustee").

                          PRELIMINARY STATEMENT

     The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. For federal income tax purposes,
the Trust Fund (exclusive of the Carryover Reserve Fund and the Pre-Funding
Account and the Trust Fund's rights with respect to payments received under the
Corridor Contract), will consist of three real estate mortgage investment
conduits (each a "REMIC" or, in the alternative, "REMIC 1," "REMIC 2" and the
"Master REMIC," respectively). 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
represents ownership of the sole class of residual interest in each of REMIC 1,
REMIC 2 and the Master REMIC. The Master REMIC will hold as assets the several
classes of uncertificated REMIC 2 Interests (other than the R-2 Interest).
REMIC 2 will hold as assets the several classes of uncertificated REMIC 1
Interests (other than the R-1 Interest). REMIC 1 will hold as assets all the
property of the Trust Fund (excluding the Carryover Reserve Fund and the
Pre-Funding Account and the Trust Fund's rights with respect to payments
received under the Corridor Contract). For federal income tax purposes, each
REMIC 2 and REMIC 1 Interest (other than the R-1 Interest and the R-2 Interest)
is hereby designated as a regular interest in its respective REMIC. The latest
possible maturity date of all REMIC regular interests created in this Agreement
shall be the Latest Possible Maturity Date.

     REMIC 1:

          The REMIC 1 Interests will have the principal balances and
pass-through rates as set forth below.

(1)  Except for the Accrual Interest, this REMIC 2 Interest has a principal
     balance that is initially equal to 50% of its Corresponding Certificate
     Class issued by the Master REMIC. Principal payments, both scheduled and
     prepaid, Realized Losses, Subsequent Recoveries and interest accruing on
     the Accrual Interest will be allocated to this class to maintain its size
     relative to its Corresponding Certificate Class (that is, 50%) with any
     excess payments of principal, Realized Losses and Subsequent Recoveries
     being allocated to the Accrual Interest in such manner as to cause the
     principal balance of the Accrual Interest to have a principal balance
     equal to (a) 50% of the principal balance of the Mortgage Loans plus (b)
     50% of the Overcollateralized Amount for such Distribution Date.

(1)  The Certificates will accrue interest at the related Pass-Through Rates
     identified in this Agreement. For federal income tax purposes, the
     Pass-Through Rate in respect of each Certificate shall be subject to a
     cap equal to the Net Rate Cap. Any entitlement of any Class of
     Certificates to Net Rate Carryover will be treated as paid by the Master
     REMIC to the Class C Certificates and then paid to such Class of
     Certificates pursuant to a limited recourse cap contract as described in
     Section 8.11 herein.

                                      4
<PAGE>

(2)  The Class C Certificates have no Certificate Principal Balance.

(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 REMIC 2 X Interest and (b) a specified
     portion of the interest on the REMIC 1 "I" and "S" Interests equal to the
     excess of the Net Rate Cap over the product of two and the weighted
     average interest rate of the REMIC 2 Regular Interests (other than the P,
     R-2 and X Interests) with each such Class other than the Accrual
     Interest, subject to a cap equal to the Pass-Through Rate of the
     Corresponding Master REMIC Class and the Accrual Interest subject to a
     cap of 0.00%. The Pass-Through Rate of the Class C Certificates shall be
     a rate sufficient to entitle the class to all interest accrued on the
     REMIC 1 "I" and "S" Interests less the interest accrued on the other
     Certificates issued by the Master REMIC. The Class C Distributable Amount
     for any Distribution Date is payable from current interest on the
     Mortgage Loans.

(4)  For each Distribution Date the Class P Certificates are entitled to all
     Prepayment Charges distributed with respect to the REMIC 2 Class P
     Interests.

(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 a REMIC
regular interest, without 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 be entitled to any cash flows pursuant to this agreement
except as provided in Section 3.08 hereunder. To the extent that the structure
is believed to diverge from such intention the Trustee will resolve
ambiguities to accomplish such result and will to the extent necessary rectify
any drafting errors or seek clarification to the structure without
Certificateholder approval (but with guidance of counsel selected by it with
due care and which has substantial experience with similar REMIC structures)
to accomplish such intention.

execute and deliver a Subsequent Transfer Agreement. After the execution and
delivery of such Subsequent Transfer Agreement, on the Subsequent Transfer
Date, the Trustee shall set aside in the Pre-Funding Account an amount equal to
the related Subsequent Transfer Date Purchase Amount.

          (e)     The transfer of Subsequent Mortgage Loans on the Subsequent
Transfer Date is subject to the satisfaction of each of the following
conditions:

                  (i)   the Trustee and the Underwriters will be provided
          Opinions of Counsel addressed to the Rating Agencies as with respect
          to the sale of the Subsequent Mortgage Loans conveyed on such
          Subsequent Transfer Date (such opinions being substantially similar
          to the opinions delivered on the Closing Date to the Rating Agencies
          with respect to the sale of the Initial Mortgage Loans on the Closing
          Date), to be delivered as provided in Section 2.01(f);

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

                  (iii) the Depositor shall deliver to the Trustee an Officer's
          Certificate confirming the satisfaction of each of the conditions set
          forth in this Section 2.01(e) required to be satisfied by such
          Subsequent Transfer Date;

                  (iv)  each Subsequent Mortgage Loan conveyed on such
          Subsequent 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 Subsequent Mortgage Loan set forth in this clause (iv), the
          obligation under Section 2.03(e) of this Agreement of the applicable
          Seller, to cure, repurchase or replace such Subsequent Mortgage Loan
          shall constitute the sole remedy against such Seller respecting such
          breach available to Certificateholders, the Depositor or the Trustee;

                                      41
<PAGE>

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

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

                  (vii) following the conveyance of the Subsequent Mortgage
          Loans on such Subsequent Transfer Date, the characteristics of the
          Mortgage Loans will not vary by more than the amount specified below
          (other than the percentage of Mortgage Loans secured by Mortgaged
          Properties located in the State of California, which will not exceed
          50% of the Mortgage Pool and the percentage of mortgage loans in the
          Credit Grade Categories of "C" or below, which will not exceed 10% of
          the Mortgage Loans in the Mortgage Pool) from the characteristics
          listed below; provided that for the purpose of making such
          calculations, the characteristics for any Initial Mortgage Loan made
          will be taken as of the Initial Cut-off Date and the characteristics
          for any Subsequent Mortgage Loans will be taken as of the Subsequent
          Cut-off Date;

                  (viii) none of the Sellers or the Depositor is insolvent and
          neither of the Sellers nor the Depositor will be rendered insolvent
          by the conveyance of Subsequent Mortgage Loans on such Subsequent
          Transfer Date; and

                  (ix)  the Trustee and the Underwriters will be provided with
          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 purchase of Subsequent Mortgage
          Loans 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 formed hereunder to fail to
          qualify as a REMIC, such opinion to be delivered as provided in
          Section 2.01(f).

          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 six Business Days after each Subsequent Transfer Date,
upon (1) delivery to the Trustee by the Depositor of the Opinions of Counsel
referred to in Section 2.01(e)(i) and (e)(ix), (2) delivery to the Trustee by
CHL (on behalf of each Seller) of a Loan

Number and Borrower Identification Mortgage Loan Schedule reflecting the
Subsequent Mortgage Loans conveyed on such Subsequent Transfer Date, (3)
deposit in the Certificate Account by the Master Servicer on behalf of the
Sellers of the applicable Subsequent Certificate Account Deposit, and (4)
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 the applicable Seller the
Subsequent Transfer Date Transfer Amount from such funds that were set aside
in the Pre-Funding Account pursuant to Section 2.01(d). The positive
difference, if any, between the Subsequent Transfer Date Transfer Amount and
the Subsequent Transfer Date Purchase Amount shall be re-invested by the
Trustee in the Pre-Funding Account.

          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 each Subsequent 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 Subsequent
Mortgage Loans conveyed on such Subsequent Transfer Date conform to the
characteristics described in Section 2.01(e)(vi) and (vii).

          (g)     In connection with the transfer and assignment of each
Mortgage Loan, the Depositor has delivered to, and deposited with, the
Co-Trustee (or, in the case of the Delay Delivery Mortgage Loans, will deliver
to, and deposit with, the Co-Trustee within the time periods specified in the
definition of Delay Delivery Mortgage Loans) (except as provided in clause (vi)
below) for the benefit of the Certificateholders, the following documents or
instruments with respect to each such Mortgage Loan so assigned (with respect
to each Mortgage Loan, clause (i) through (vi) below, together, the "Mortgage
File" for each such Mortgage Loan):

                  (i)   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 that show 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, if the original Mortgage
          Note has been lost or destroyed and not replaced, an original lost
          note affidavit, stating that the original Mortgage Note was lost or
          destroyed, together with a copy of the related Mortgage Note;

                  (ii)  in the case of each Mortgage Loan that is not a MERS
          Mortgage Loan, the original recorded Mortgage, and in the case of
          each MERS Mortgage Loan, the original Mortgage, noting the presence
          of the MIN of the Mortgage Loan and language indicating that the
          Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan, 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;

                                      43
<PAGE>

                  (iii) in the case of each Mortgage Loan that is not a MERS
          Mortgage Loan, a duly executed assignment of the Mortgage to
          "Asset-Backed Certificates, Series 2005-AB1, CWABS, Inc., by The Bank
          of New York, a New York banking corporation, as trustee under the
          Pooling and Servicing Agreement dated as of March 1, 2005, without
          recourse" (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 such
          assignment relates);

                  (iv)  the original recorded assignment or assignments of the
          Mortgage together with all interim recorded assignments of such
          Mortgage (noting the presence of a MIN in the case of each MERS
          Mortgage Loan);

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

                  (vi)  the original or duplicate original lender's title policy
          or a printout of the electronic equivalent and all riders thereto or,
          in the event such original title policy has not been received from
          the insurer, such original or duplicate original lender's title
          policy and all riders thereto shall be delivered within one year of
          the Closing Date.

          In addition, in connection with the assignment of any MERS Mortgage
Loan, each Seller agrees that it will cause, at such Seller's own expense, the
MERS(R) System to indicate (and provide evidence to the Trustee that it has
done so) that such Mortgage Loans have been assigned by such Seller to the
Trustee in accordance with this Agreement 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 (a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY
THE FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such
Mortgage Loans. The Sellers further agree that they will not, and will not
permit the Master Servicer to, and the Master Servicer agrees that it will
not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan 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 a Seller cannot deliver the original recorded Mortgage or
all interim recorded assignments of the Mortgage satisfying the requirements
of clause (ii), (iii) or (iv) concurrently with the execution and delivery
hereof, such Seller shall deliver or cause to be delivered to the Co-Trustee a
true copy of such Mortgage and of each such undelivered interim assignment of
the Mortgage each certified by such Seller, the applicable title company,
escrow agent or attorney, or the originator of such Mortgage, as the case may
be, to be a true and complete copy of the original Mortgage or assignment of
Mortgage submitted for recording. For any such Mortgage Loan that is not a
MERS Mortgage Loan each Seller shall promptly deliver or cause to be delivered
to the Co-Trustee such original Mortgage and such assignment or assignments
with

                                      44
<PAGE>

evidence of recording indicated thereon upon receipt thereof from the public
recording official, or a copy thereof, certified, if appropriate, by the
relevant recording office, but in no event shall any such delivery be made
later than 270 days following the Closing Date; provided that in the event
that by such date such Seller is unable to deliver or cause to be delivered
each such Mortgage and each 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 interim assignment, because the related Mortgage has not
been returned by the appropriate recording office, such Seller shall deliver
or cause to be delivered such documents to the Co-Trustee as promptly as
possible upon receipt thereof. If the public recording office in which a
Mortgage or interim assignment thereof is recorded retains the original of
such Mortgage or assignment, a copy of the original Mortgage or assignment so
retained, with evidence of recording thereon, certified to be true and
complete by such recording office, shall satisfy a Seller's obligations in
Section 2.01. If any document submitted for recording pursuant to this
Agreement is (x) lost prior to recording or rejected by the applicable
recording office, the applicable Seller shall immediately prepare or cause to
be prepared a substitute and submit it for recording, and shall deliver copies
and originals thereof in accordance with the foregoing or (y) lost after
recording, the applicable Seller shall deliver to the Co-Trustee a copy of
such document certified by the applicable public recording office to be a true
and complete copy of the original recorded document. Each Seller shall
promptly forward or cause to be forwarded to the Co-Trustee (x) from time to
time additional original documents evidencing an assumption or modification of
a Mortgage Loan and (y) any other documents required to be delivered by the
Depositor or the Master Servicer to the Co-Trustee within the time periods
specified in this Section 2.01.

          With respect to each Mortgage Loan other than a MERS Mortgage Loan
as to which the related Mortgaged Property and Mortgage File are located in
(a) the State of California or (b) any other jurisdiction under the laws of
which the recordation of the assignment specified in clause (iii) above 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 CHL
to the Trustee, and a copy to the Rating Agencies, in lieu of recording the
assignment specified in clause (iii) above, the applicable Seller may deliver
an unrecorded assignment in blank, in form otherwise suitable for recording to
the Co-Trustee; provided that if the related Mortgage has not been returned
from the applicable public recording office, such assignment, or any copy
thereof, of the Mortgage may exclude the information to be provided by the
recording office. As to any Mortgage Loan other than a MERS Mortgage Loan, the
procedures of the preceding sentence shall be applicable only so long as the
related Mortgage File is maintained in the possession of the Co-Trustee in the
State or jurisdiction described in such sentence. In the event that with
respect to Mortgage Loans other than MERS Mortgage Loans (i) any Seller, the
Depositor, the Master Servicer or the NIM Insurer gives written notice to the
Trustee that recording is required to protect the right, title and interest of
the Trustee on behalf of the Certificateholders in and to any Mortgage Loan,
(ii) a court recharacterizes any sale of the Mortgage Loans as a financing, or
(iii) as a result of any change in or amendment to the laws of the State or
jurisdiction described in the first sentence of this paragraph or any
applicable political subdivision thereof, or any change in official position
regarding application or interpretation of such laws, including a holding by a
court of competent jurisdiction, such recording is so required, the Co-Trustee
shall complete the assignment in the manner specified in clause (iii) of the
second paragraph of this Section 2.01(g) and CHL shall submit or cause to be
submitted for recording as specified above or, should CHL fail to perform such
obligations, the Trustee shall cause the Master Servicer, at

                                      45
<PAGE>

the Master Servicer's expense, to cause each such previously unrecorded
assignment to be submitted for recording as specified above. In the event a
Mortgage File is released to the Master Servicer as a result of the Master
Servicer's having completed a Request for Document Release, the Trustee shall
complete the assignment of the related Mortgage in the manner specified in
clause (iii) of the second paragraph of this Section 2.01(g).

          So long as the Co-Trustee or its agent maintains an office in the
State of California, the Co-Trustee or its agent shall maintain possession of
and not remove or attempt to remove from the State of California any of the
Mortgage Files as to which the related Mortgaged Property is located in such
State. In the event that a Seller fails to record an assignment of a Mortgage
Loan as herein provided within 90 days of notice of an event set forth in
clause (i), (ii) or (iii) of the above paragraph, the Master Servicer shall
prepare and, if required hereunder, file such assignments for recordation in
the appropriate real property or other records office. Each Seller hereby
appoints the Master Servicer (and any successor servicer hereunder) as its
attorney-in-fact with full power and authority acting in its stead for the
purpose of such preparation, execution and filing.

          In the case of Mortgage Loans that become the subject of a Principal
Prepayment between the Closing Date (in the case of Initial Mortgage Loans) or
related Subsequent Transfer Date (in the case of Subsequent Mortgage Loans)
and the Cut-off Date, CHL shall deposit or cause to be deposited in the
Certificate Account the amount required to be deposited therein with respect
to such payment pursuant to Section 3.05 hereof.

          Notwithstanding anything to the contrary in this Agreement, within
thirty days after the Closing Date (in the case of Initial Mortgage Loans) or
within twenty days after the related Subsequent Transfer Date (in the case of
Subsequent Mortgage Loans), CHL (on behalf of each Seller) shall either (i)
deliver to the Co-Trustee the Mortgage File as required pursuant to this
Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase the
Delay Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage
Loan for a Replacement Mortgage Loan, which repurchase or substitution shall
be accomplished in the manner and subject to the conditions set forth in
Section 2.03, provided that if CHL fails to deliver a Mortgage File for any
Delay Delivery Mortgage Loan within the period provided in the prior sentence,
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 CHL shall have five (5) Business Days to cure such
failure to deliver. CHL shall promptly provide each Rating Agency with written
notice of any cure, repurchase or substitution made pursuant to the proviso of
the preceding sentence. On or before the thirtieth (30th) day (or if such
thirtieth day is not a Business Day, the succeeding Business Day) after the
Closing Date (in the case of Initial Mortgage Loans) or within twenty days
after the related Subsequent Transfer Date (in the case of Subsequent Mortgage
Loans), the Trustee shall, in accordance with the provisions of Section 2.02,
send a Delay Delivery Certification substantially in the form annexed hereto
as Exhibit G-3 (with any applicable exceptions noted thereon) for all Delay
Delivery Mortgage Loans delivered within thirty (30) days after such date. The
Trustee will promptly send a copy of such Delay Delivery Certification to each
Rating Agency.

          The Trust Fund will not acquire or hold any Mortgage Loan that would
violate the representations made by CHL in Section 2.03(b)(70) or (72).

          Section 2.02  Acceptance by Trustee of the Mortgage Loans.
                        --------------------------------------------

          (a)     The Co-Trustee acknowledges receipt, subject to the
limitations contained in and any exceptions noted in the Initial Certification
in the form annexed hereto as Exhibit G-1 and in the list of exceptions
attached thereto, of the documents referred to in clauses (i) and (iii) of
Section 2.01(g) above with respect to the Initial Mortgage Loans and all other
assets included in the Trust Fund 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 included in the Trust
Fund, in trust for the exclusive use and benefit of all present and future
Certificateholders.

          The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and CHL (on behalf of each Seller) an Initial
Certification substantially in the form annexed hereto as Exhibit G-1 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification), the documents described in Section 2.01(g)(i) and, in the
case of each Initial Mortgage Loan that is not a MERS Mortgage Loan, the
documents described in Section 2.01(g)(iii) with respect to such Initial
Mortgage Loans as are in the Co-Trustee's possession and based on its review
and examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Initial Mortgage Loan. The Trustee
agrees to execute and deliver within 30 days after the Closing Date to the
Depositor, the Master Servicer and CHL (on behalf of each Seller) an Interim
Certification substantially in the form annexed hereto as Exhibit G-2 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification) all documents required to be delivered to the Co-Trustee
pursuant to the Agreement with respect to such Initial Mortgage Loans are in
its possession (except those documents described in Section 2.01(g)(vi)) and
based on its review and examination and only as to the foregoing documents,
(i) such documents appear regular on their face and relate to such Initial
Mortgage Loan, and (ii) the information set forth in items (i), (iv), (v),
(vi), (viii), (ix) and (xiv) through (xx) of the definition of the "Mortgage
Loan Schedule" accurately reflects information set forth in the Mortgage File.
On or before the thirtieth (30th) day after the Closing Date (or if such
thirtieth day is not a Business Day, the succeeding Business Day), the Trustee
shall deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) a Delay Delivery Certification with respect to the Initial Mortgage
Loans substantially in the form annexed hereto as Exhibit G-3, with any
applicable exceptions noted thereon. The Co-Trustee or the Trustee, as
applicable, shall be under no duty or obligation to inspect, review or examine
such 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.

          Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller), and to any Certificateholder that so requests, a Final Certification
with respect to the Initial Mortgage Loans substantially in the form annexed
hereto as Exhibit H, with any applicable exceptions noted thereon.

                                      47
<PAGE>

          In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee, at the Trustee's direction, shall review
each Mortgage File with respect to the Initial Mortgage Loans to determine
that such Mortgage File contains the following documents:

                  (i)   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 that show 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, if the original Mortgage
          Note has been lost or destroyed and not replaced, an original lost
          note affidavit, stating that the original Mortgage Note was lost or
          destroyed, together with a copy of the related Mortgage Note;

                  (ii)  in the case of each Initial Mortgage Loan that is not a
          MERS Mortgage Loan, the original recorded Mortgage, and in the case
          of each Initial Mortgage Loan that is a MERS Mortgage Loan, the
          original Mortgage, noting the presence of the MIN of the Initial
          Mortgage Loan and language indicating that the Mortgage Loan is a MOM
          Loan if the Initial Mortgage Loan is a MOM Loan, with evidence of
          recording indicated thereon, or a copy of the Mortgage certified by
          the public recording office in which Mortgage has been recorded;

                  (iii) in the case of each Initial Mortgage Loan that is not a
          MERS Mortgage Loan, a duly executed assignment of the Mortgage in the
          form permitted by Section 2.01;

                  (iv) the original recorded assignment or assignments of the
          Mortgage together with all interim recorded assignments of such
          Mortgage (noting the presence of a MIN in the case of each MERS
          Mortgage Loan);

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

                  (vi)  the original or duplicate original lender's title policy
          or a printout of the electronic equivalent and all riders thereto.

          If, in the course of such review, the Co-Trustee finds any document
or documents constituting a part of such Mortgage File that do not meet the
requirements of clauses (i)-(iv) and (vi) above, the Trustee shall include
such exceptions in such Final Certification (and the Trustee shall state in
such Final Certification whether any Mortgage File does not then include the
original or duplicate original lender's title policy or a printout of the
electronic equivalent and all riders thereto). If the public recording office
in which a Mortgage or assignment thereof is recorded retains the original of
such Mortgage or assignment, a copy of the original Mortgage or assignment so
retained, with evidence of recording thereon, certified to be true and
complete by such recording office, shall be deemed to satisfy the requirements
of clause (ii), (iii) or (iv) above, as applicable. CHL shall promptly correct
or cure such defect referred to above within 90

                                      48

days from the date it was so notified of such defect and, if CHL does not
correct or cure such defect within such period, CHL shall either (A) if the
time to cure such defect expires prior to the end of the second anniversary of
the Closing Date, substitute for the related Initial Mortgage Loan a
Replacement 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 Initial Mortgage Loan from the Trust Fund within 90 days from
the date CHL was notified of such defect in writing at the Purchase Price of
such Initial Mortgage Loan; provided that any such substitution pursuant to
(A) above or repurchase 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 and any substitution pursuant to (A) above shall not be effected prior
to the additional delivery to the Co-Trustee of a Request for File Release. No
substitution will be made in any calendar month after the Determination Date
for such month. The Purchase Price for any such Initial Mortgage Loan shall be
deposited by CHL in the Certificate Account and, upon receipt of such deposit
and Request for File Release with respect thereto, the Co-Trustee shall
release the related Mortgage File to CHL and shall execute and deliver at
CHL's request such instruments of transfer or assignment as CHL has prepared,
in each case without recourse, as shall be necessary to vest in CHL, or a
designee, the Trustee's interest in any Initial Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases an
Initial Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall
cause MERS to execute and deliver an assignment of the Mortgage in recordable
form to transfer the Mortgage from MERS to CHL and shall cause such Mortgage
to be removed from registration on the MERS(R) System in accordance with MERS'
rules and regulations.

          The Co-Trustee shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth
herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of
such Seller from time to time.

          It is understood and agreed that the obligation of CHL to substitute
for or to purchase any Mortgage Loan that does not meet the requirements of
Section 2.02(a) above shall constitute the sole remedy respecting such defect
available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against any Seller.

          It is understood and agreed that the obligation of CHL to substitute
for or to purchase, pursuant to Section 2.02(a), any Initial Mortgage Loan
whose Mortgage File contains any document or documents that does not meet the
requirements of clauses (i)-(iv) and (vi) above and which defect is not
corrected or cured by CHL within 90 days from the date it was notified of such
defect, shall constitute the sole remedy respecting such defect available to
the Trustee, the Co-Trustee, the Depositor and any Certificateholder against
any Seller.

          (b)     The Trustee agrees to execute and deliver on the Subsequent
Transfer Date to the Depositor, the Master Servicer and CHL (on behalf of each
Seller) an Initial Certification substantially in the form annexed hereto as
Exhibit G-4 to the effect that, as to each Subsequent Mortgage Loan listed in
the Mortgage Loan Schedule (other than any Subsequent Mortgage Loan paid in
full or any Subsequent Mortgage Loan specifically identified in such
certification as not covered by such certification), the documents described in
Section 2.01(g)(i)

                                      49
<PAGE>

and, in the case of each Subsequent Mortgage Loan that is not a MERS Mortgage
Loan, the documents described in Section 2.01(g)(iii), with respect to such
Subsequent Mortgage Loan are in its possession, and based on its review and
examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Subsequent Mortgage Loan.

          The Trustee agrees to execute and deliver within 30 days after the
Subsequent Transfer Date to the Depositor, the Master Servicer and CHL (on
behalf of each Seller) an Interim Certification substantially in the form
annexed hereto as Exhibit G-2 to the effect that, as to each Subsequent
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Subsequent
Mortgage Loan paid in full or any Subsequent Mortgage Loan specifically
identified in such certification as not covered by such certification), all
documents required to be delivered to it pursuant to this Agreement with
respect to such Subsequent Mortgage Loan are in its possession (except those
described in Section 2.01(g)(vi)) and based on its review and examination and
only as to the foregoing documents, (i) such documents appear regular on their
face and relate to such Subsequent Mortgage Loan, and (ii) the information set
forth in items (i), (iv), (v), (vi), (viii), (ix) and (xiv) through (xx) of
the definition of the "Mortgage Loan Schedule" accurately reflects information
set forth in the Mortgage File. On or before the thirtieth (30th) day after
the Subsequent Transfer Date (or if such thirtieth day is not a Business Day,
the succeeding Business Day), the Trustee shall deliver to the Depositor, the
Master Servicer and CHL (on behalf of each Seller) a Delay Delivery
Certification with respect to the Subsequent Mortgage Loans substantially in
the form annexed hereto as Exhibit G-3, with any applicable exceptions noted
thereon, together with a Subsequent Certification substantially in the form
annexed hereto as Exhibit G-4. The Trustee shall be under no duty or
obligation to inspect, review or examine such 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.

          Not later than 180 days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, CHL (on behalf of
each Seller) and to any Certificateholder that so requests a Final
Certification with respect to the Subsequent Mortgage Loans substantially in
the form annexed hereto as Exhibit H, with any applicable exceptions noted
thereon.

          In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee shall review each Mortgage File with
respect to the Subsequent Mortgage Loans to determine that such Mortgage File
contains the following documents:

                  (i)   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 that show 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, if the original Mortgage
          Note has been lost or destroyed and not replaced, an original lost
          note

                                      50
<PAGE>

          affidavit, stating that the original Mortgage Note was lost
          or destroyed, together with a copy of the related Mortgage Note;

                  (ii)  in the case of each Subsequent Mortgage Loan that is not
          a MERS Mortgage Loan, the original recorded Mortgage, and in the case
          of each Subsequent Mortgage Loan that is a MERS Mortgage Loan, the
          original Mortgage, noting the presence of the MIN of the Subsequent
          Mortgage Loan and language indicating that the Subsequent Mortgage
          Loan is a MOM Loan if the Subsequent Mortgage Loan is a MOM Loan,
          with evidence of recording indicated thereon, or a copy of the
          Mortgage certified by the public recording office in which Mortgage
          has been recorded;

                  (iii) in the case of each Subsequent Mortgage Loan that is
          not a MERS Mortgage Loan, a duly executed assignment of the Mortgage
          in the form permitted by Section 2.01;

                  (iv)  the original recorded assignment or assignments of the
          Mortgage together with all interim recorded assignments of such
          Mortgage (noting the presence of a MIN in the case of each MERS
          Mortgage Loan);

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

                  (vi)  the original or duplicate original lender's title policy
          or a printout of the electronic equivalent and all riders thereto.

          If, in the course of such review, the Co-Trustee finds any document
or documents constituting a part of such Mortgage File that do not meet the
requirements of clauses (i)-(iv) and (vi) above, the Trustee shall include
such exceptions in such Final Certification (and the Trustee shall state in
such Final Certification whether any Mortgage File does not then include the
original or duplicate original lender's title policy or a printout of the
electronic equivalent and all riders thereto). If the public recording office
in which a Mortgage or assignment thereof is recorded retains the original of
such Mortgage or assignment, a copy of the original Mortgage or assignment so
retained, with evidence of recording thereon, certified to be true and
complete by such recording office, shall be deemed to satisfy the requirements
of clause (ii), (iii) or (iv) above, as applicable. CHL shall promptly correct
or cure such defect referred to above within 90 days from the date it was so
notified of such defect and, if CHL does not correct or cure such defect
within such period, CHL shall either (A) if the time to cure such defect
expires prior to the end of the second anniversary of the Closing Date,
substitute for the related Subsequent Mortgage Loan a Replacement 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 Subsequent
Mortgage Loan from the Trust Fund within 90 days from the date CHL was
notified of such defect in writing at the Purchase Price of such Subsequent
Mortgage Loan; provided that any such substitution pursuant to (A) above or
repurchase 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 and
any substitution pursuant to (A) above shall not be effected prior to the
additional delivery to the Trustee of a Request for File Release. No
substitution will be made in any calendar month after the Determination Date
for such month. The Purchase Price for any such Subsequent Mortgage

                                      51
<PAGE>

Loan shall be deposited by CHL in the Certificate Account and, upon receipt of
such deposit and Request for File Release with respect thereto, the Trustee
shall release the related Mortgage File to CHL and shall execute and deliver
at CHL's request such instruments of transfer or assignment as CHL has
prepared, in each case without recourse, as shall be necessary to vest in CHL,
or a designee, the Trustee's interest in any Subsequent Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases a
Subsequent Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer
shall cause MERS to execute and deliver an assignment of the Mortgage in
recordable form to transfer the Mortgage from MERS to CHL and shall cause such
Mortgage to be removed from registration on the MERS(R) System in accordance
with MERS' rules and regulations.

          The Co-Trustee shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth
herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of
such Seller from time to time.

         It is understood and agreed that the obligation of the Sellers to
substitute for or to purchase, pursuant to Section 2.02(b), any Subsequent
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect
is not corrected or cured by such Seller within 90 days from the date it was
notified of such defect, shall constitute the sole remedy respecting such
defect available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against the Sellers.

               (12) Immediately prior to the assignment of each CHL Mortgage
     Loan to the Depositor, CHL had good title to, and was the sole owner of,

     Loans and as of the related Subsequent Transfer Date in the case of the
     Subsequent Mortgage Loans, neither CHL nor any prior holder of any
     Mortgage has modified the Mortgage in any material respect (except that a
     Mortgage Loan may have been modified by a written instrument that has
     been recorded or submitted for recordation, if necessary, to protect the
     interests of the Certificateholders and the original or a copy of which
     has been delivered to the Trustee); satisfied, cancelled or subordinated
     such Mortgage in whole or in part; released the related Mortgaged
     Property in whole or in part from the lien of such Mortgage; or executed
     any instrument of release, cancellation, modification (except as

     effective on the date of the origination of each Mortgage Loan, each such
     policy is valid and remains in full force and effect, and each such
     policy was issued by a title insurer qualified to do business in the
     jurisdiction where the Mortgaged Property is located and acceptable to
     Fannie Mae and Freddie Mac and is in a form acceptable to Fannie Mae and
     Freddie Mac, which policy insures the Sellers and successor owners of
     indebtedness secured by the insured Mortgage, as to the first priority
     lien, of the Mortgage subject to the exceptions set forth in paragraph
     (11) above; to the best of CHL's knowledge, no claims have been made
     under such mortgage title insurance policy and no prior holder of the
     related Mortgage, including any Seller,

                                      56
<PAGE>

     has done, by act or omission, anything that would impair the coverage of
     such mortgage title insurance policy.

               (19) No Initial Mortgage Loan was the subject of a Principal
     Prepayment in full between the Initial Cut-off Date and the Closing Date.
     No Subsequent Mortgage Loan was the subject of a Principal Prepayment in
     full between the Subsequent Cut-off Date and the Subsequent Transfer
     Date.

               (20) To the best of CHL's knowledge, all of the improvements
     that were included for the purpose of determining the Appraised Value of
     the Mortgaged Property lie wholly within the boundaries and building
     restriction lines of such property, and no improvements on adjoining
     properties encroach upon the Mortgaged Property.

               (21) To the best of CHL's knowledge, no improvement located on
     or being part of the Mortgaged Property is in violation of any applicable
     zoning law or regulation. To the best of CHL's knowledge, all
     inspections, licenses and certificates required to be made or issued with
     respect to all occupied portions of the Mortgaged Property and, with
     respect to the use and occupancy of the same, including but not limited
     to certificates of occupancy and fire underwriting certificates, have
     been made or obtained from the appropriate authorities, unless the lack
     thereof would not have a material adverse effect on the value of such
     Mortgaged Property, and the Mortgaged Property is lawfully occupied under
     applicable law.

               (22) The Mortgage Note and the related Mortgage are genuine,
     and each is the legal, valid and binding obligation of the maker thereof,
     enforceable in accordance with its terms and under applicable law, except
     that (a) the enforceability thereof may be limited by bankruptcy,
     insolvency, moratorium, receivership and other similar laws relating to
     creditors' rights generally and (b) the remedy of specific performance
     and injunctive and other forms of equitable relief may be subject to
     equitable defenses and to the discretion of the court before which any
     proceeding therefor may be brought. To the best of CHL's knowledge, all
     parties to the Mortgage Note and the Mortgage had legal capacity to
     execute the Mortgage Note and the Mortgage and each Mortgage Note and
     Mortgage have been duly and properly executed by such parties.

               (23) The proceeds of the Mortgage Loan have been fully
     disbursed, there is no requirement for future advances thereunder, and
     any and all requirements as to completion of any on-site or off-site
     improvements and as to disbursements of any escrow funds therefor have
     been complied with. All costs, fees and expenses incurred in making, or
     closing or recording the Mortgage Loan were paid.

               (24) The related Mortgage contains customary and enforceable
     provisions that render the rights and remedies of the holder thereof
     adequate for the realization against the Mortgaged Property of the
     benefits of the security, including, (i) in the case of a Mortgage
     designated as a deed of trust, by trustee's sale, and (ii) otherwise by
     judicial foreclosure.

                                      57
<PAGE>

               (25) With respect to each Mortgage constituting a deed of
     trust, a trustee, duly qualified under applicable law to serve as such,
     has been properly designated and currently so serves and is named in such
     Mortgage, and no fees or expenses are or will become payable by the
     Certificateholders to the trustee under the deed of trust, except in
     connection with a trustee's sale after default by the Mortgagor.

               (26) Each Mortgage Note and each Mortgage is acceptable in form
     to Fannie Mae and Freddie Mac.

               (27) There exist no deficiencies with respect to escrow
     deposits and payments, if such are required, for which customary
     arrangements for repayment thereof have not been made, and no escrow
     deposits or payments of other charges or payments due the Sellers have
     been capitalized under the Mortgage or the related Mortgage Note.

               (28) The origination, underwriting, servicing and collection
     practices with respect to each Mortgage Loan have been in all respects
     legal, proper, prudent and customary in the mortgage lending and
     servicing business, as conducted by prudent lending institutions which
     service mortgage loans of the same type in the jurisdiction in which the
     Mortgaged Property is located.

               (29) There is no pledged account or other security other than
     real estate securing the Mortgagor's obligations.

               (30) No Mortgage Loan has a shared appreciation feature, or
     other contingent interest feature.

               (31) Each Mortgage Loan contains a customary "due on sale"
     clause.

               (32) No less than approximately the percentage specified in the
     Collateral Schedule of the Initial Mortgage Loans are secured by single
     family detached dwellings. No more than approximately the percentage
     specified in the Collateral Schedule of the Initial Mortgage Loans are
     secured by two- to four-family dwellings. No more than approximately the
     percentage specified in the Collateral Schedule of the Initial Mortgage
     Loans are secured by low-rise condominium units. No more than
     approximately the percentage specified in the Collateral Schedule of the
     Initial Mortgage Loans are secured by high-rise condominium units. No
     more than approximately the percentage specified in the Collateral
     Schedule of the Initial Mortgage Loans are secured by manufactured
     housing. No more than approximately the percentage specified in the
     Collateral Schedule of the Initial Mortgage Loans are secured by PUDs.

               (33) Each Initial Mortgage Loan was originated on or after the
     date specified in the Collateral Schedule.

               (34) Each Initial Mortgage Loan, other than a Two-Year Hybrid
     Mortgage Loan or a Three-Year Hybrid Mortgage Loan, had an initial
     Adjustment Date no later than the applicable date specified on the
     Collateral Schedule; each Initial Mortgage Loan that is a Two-Year Hybrid
     Mortgage Loan had an initial Adjustment Date no later than the applicable
     date specified on the Collateral Schedule; and each Initial

                                      58
<PAGE>

     Mortgage Loan that is a Three-Year Hybrid Mortgage Loan had an initial
     Adjustment Date no later than the applicable date specified on the
     Collateral Schedule.

               (35) Approximately the percentage specified in the Collateral
     Schedule of the Initial Mortgage Loans provide for a prepayment penalty.

               (36) On the basis of representations made by the Mortgagors in
     their loan applications, no more than approximately the percentage
     specified in the Collateral Schedule of the Initial Mortgage Loans are
     secured by investor properties, and no less than approximately the
     percentage specified in the Collateral Schedule of the Initial Mortgage
     Loans are secured by owner-occupied Mortgaged Properties that are primary
     residences.

               (37) At the Cut-off Date, the improvements upon each Mortgaged
     Property are covered by a valid and existing hazard insurance policy with
     a generally acceptable carrier that provides for fire and extended
     coverage and coverage for such other hazards as are customary in the area
     where the Mortgaged Property is located 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 (a) the
     outstanding principal balance of the Mortgage Loan and (b) 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. If the
     Mortgaged Property is a condominium unit, it is included under the
     coverage afforded by a blanket policy for the condominium unit. All such
     individual insurance policies and all flood policies referred to in item
     (38) below contain a standard mortgagee clause naming the applicable
     Seller or the original mortgagee, and its successors in interest, as
     mortgagee, and the applicable Seller has received no notice that any
     premiums due and payable thereon have not been paid; the Mortgage
     obligates the Mortgagor thereunder to maintain all such insurance,
     including flood insurance, at the Mortgagor's cost and expense, and upon
     the Mortgagor's failure to do so, authorizes the holder of the Mortgage
     to obtain and maintain such insurance at the Mortgagor's cost and expense
     and to seek reimbursement therefor from the Mortgagor.

               (38) If the Mortgaged Property is in an area identified in the
     Federal Register by the Federal Emergency Management Agency as having
     special flood hazards, a flood insurance policy in a form meeting the
     requirements of the current guidelines of the Flood Insurance
     Administration is in effect with respect to such Mortgaged Property with
     a generally acceptable carrier in an amount representing coverage not
     less than the least of (A) the original outstanding principal balance of
     the Mortgage Loan, (B) the minimum amount required to compensate for
     damage or loss on a replacement cost basis, or (C) the maximum amount of
     insurance that is available under the Flood Disaster Protection Act of
     1973, as amended.

               (39) To the best of CHL's knowledge, there is no proceeding
     occurring, pending or threatened for the total or partial condemnation of
     the Mortgaged Property.

               (40) There is no material monetary default existing under any
     Mortgage or the related Mortgage Note and, to the best of CHL's
     knowledge, there is no material

                                      59
<PAGE>

     event that, with the passage of time or with notice and the expiration of
     any grace or cure period, would constitute a default, breach, violation
     or event of acceleration under the Mortgage or the related Mortgage Note;
     and no Seller has waived any default, breach, violation or event of
     acceleration.

               (41) Each Mortgaged Property is improved by a one- to
     four-family residential dwelling, including condominium units and
     dwelling units in PUDs. To the best of CHL's knowledge, no improvement to
     a Mortgaged Property includes a cooperative or a mobile home or
     constitutes other than real property under state law.

               (42) Each Mortgage Loan is being serviced by the Master
     Servicer.

               (43) Any future advances made prior to the Cut-off Date have
     been consolidated with the outstanding principal amount secured by the
     Mortgage, and the secured principal amount, as consolidated, bears a
     single interest rate and single repayment term reflected on the Mortgage
     Loan Schedule. The consolidated principal amount does not exceed the
     original principal amount of the Mortgage Loan. The Mortgage Note does
     not permit or obligate the Master Servicer to make future advances to the
     Mortgagor at the option of the Mortgagor.

               (44) All taxes, governmental assessments, insurance premiums,
     water, sewer and municipal charges, leasehold payments or ground rents
     that previously became due and owing have been paid, or an escrow of
     funds has been established in an amount sufficient to pay for every such
     item that remains unpaid and that has been assessed, but is not yet due
     and payable. Except for (A) payments in the nature of escrow payments,
     and (B) interest accruing from the date of the Mortgage Note or date of
     disbursement of the Mortgage proceeds, whichever is later, to the day
     that precedes by one month the Due Date of the first installment of
     principal and interest, including without limitation, taxes and insurance
     payments, the Master Servicer has not advanced funds, or induced,
     solicited or knowingly received any advance of funds by a party other
     than the Mortgagor, directly or indirectly, for the payment of any amount
     required by the Mortgage.

               (45) The Mortgage Loans originated by CHL were underwritten in
     all material respects in accordance with CHL's underwriting guidelines
     for credit blemished quality mortgage loans or, with respect to Mortgage
     Loans purchased by CHL were underwritten in all material respects in
     accordance with customary and prudent underwriting guidelines generally
     used by originators of credit blemished quality mortgage loans.

               (46) Prior to the approval of the Mortgage Loan application, an
     appraisal of the related Mortgaged Property was obtained from a qualified
     appraiser, duly appointed by the originator, who had no interest, direct
     or indirect, in the Mortgaged Property or in any loan made on the
     security thereof, and whose compensation is not affected by the approval
     or disapproval of the Mortgage Loan; such appraisal is in a form
     acceptable to Fannie Mae and Freddie Mac.

                                      60
<PAGE>

               (47) None of the Mortgage Loans is a graduated payment mortgage
     loan or a growing equity mortgage loan, and no Mortgage Loan is subject
     to a buydown or similar arrangement.

               (48) The Mortgage Rates borne by the Initial Mortgage Loans as
     of the Cut-off Date ranged between the approximate per annum percentages
     specified on the Collateral Schedule and the weighted average Mortgage
     Rate as of the Cut-off Date was approximately the per annum rate
     specified on the Collateral Schedule.

               (49) [Reserved.]

               (50) The Mortgage Loans were selected from among the
     outstanding one- to four-family mortgage loans in the applicable Seller's
     portfolio at the Closing Date as to which the representations and
     warranties made as to the Mortgage Loans set forth in this Section
     2.03(b) and Sections 2.03(c) and 2.03(d) can be made. No selection was
     made in a manner that would adversely affect the interests of
     Certificateholders.

               (51) The Gross Margins on the Initial Mortgage Loans range
     between the approximate percentages specified on the Collateral Schedule,
     and the weighted average Gross Margin was approximately the percentage
     specified in the Collateral Schedule.

               (52) Each of the Initial Mortgage Loans in the Mortgage Pool
     has a Due Date on or before the date specified in the Collateral
     Schedule.

               (53) The Mortgage Loans, individually and in the aggregate,
     conform in all material respects to the descriptions thereof in the
     Prospectus Supplement.

               (54) There is no obligation on the part of any Seller under the
     terms of the Mortgage or related Mortgage Note to make payments in
     addition to those made by the Mortgagor.

               (55) Any leasehold estate securing a Mortgage Loan has a term
     of not less than five years in excess of the term of the related Mortgage
     Loan.

               (56) Each Mortgage Loan represents a "qualified mortgage"
     within the meaning of Section 860(a)(3) of the Code (but without regard
     to the rule in Treasury Regulation ss. 1.860G-2(f)(2) that treats a
     defective obligation as a qualified mortgage, or any substantially
     similar successor provision) and applicable Treasury regulations
     promulgated thereunder.

               (57) No Mortgage Loan was either a "consumer credit contract"
     or a "purchase money loan" as such terms are defined in 16 C.F.R. ss. 433
     nor is any Mortgage Loan a "mortgage" as defined in 15 U.S.C. ss.
     1602(aa).

               (58) To the extent required under applicable law, each
     originator and subsequent mortgagee or servicer of the Mortgage Loan
     complied with all licensing requirements and was authorized to transact
     and do business in the jurisdiction in which

                                      61
<PAGE>

     the related Mortgaged Property is located at all times when it held or
     serviced the Mortgage Loan. Any and all requirements of any federal,
     state or local laws or regulations, including, without limitation, usury,
     truth-in-lending, real estate settlement procedures, consumer credit
     protection, anti-predatory lending, fair credit reporting, unfair
     collection practice, equal credit opportunity, fair housing and
     disclosure laws and regulations, applicable to the solicitation,
     origination, collection and servicing of such Mortgage Loan have been
     complied with in all material respects; and any obligations of the holder
     of the Mortgage Note, Mortgage and other loan documents have been
     complied with in all material respects; servicing of each Mortgage Loan
     has been in accordance with prudent mortgage servicing standards, any
     applicable laws, rules and regulations and in accordance with the terms
     of the Mortgage Notes, Mortgage and other loan documents, whether such
     origination and servicing was done by the applicable Seller, its
     affiliates, or any third party which originated the Mortgage Loan on
     behalf of, or sold the Mortgage Loan to, any of them, or any servicing
     agent of any of the foregoing;

              (59) The methodology used in underwriting the extension of credit
     for the Mortgage Loan employs objective mathematical principles which
     relate the borrower's income, assets and liabilities to the proposed
     payment and such underwriting methodology does not rely on the extent of
     the borrower's equity in the collateral as the principal determining
     factor in approving such credit extension. Such underwriting methodology
     confirmed that at the time of origination (application/approval) the
     borrower had a reasonable ability to make timely payments on the Mortgage
     Loan;

               (60) No borrower was required to purchase any credit life,
     disability, accident or health insurance product as a condition of
     obtaining the extension of credit. No borrower obtained a prepaid
     single-premium credit life, disability, accident or health insurance
     policy in connection with the origination of the Mortgage Loan;

               (61) If the Mortgage Loan provides that the interest rate on
     the principal balance of the related Mortgage Loan may be adjusted, all
     of the terms of the related Mortgage pertaining to interest rate
     adjustments, payment adjustments and adjustments of the outstanding
     principal balance have been made in accordance with the terms of the
     related Mortgage Note and applicable law and are enforceable and such
     adjustments will not affect the priority of the Mortgage lien;

               (62) The Mortgaged Property complies with all applicable laws,
     rules and regulations relating to environmental matters, including but
     not limited to those relating to radon, asbestos and lead paint and no
     Seller nor, to the best of CHL's knowledge, the Mortgagor, has received
     any notice of any violation or potential violation of such law;

               (63) There is no action, suit or proceeding pending, or to the
     best of CHL's knowledge, threatened or likely to be asserted with respect
     to the Mortgage Loan against or affecting any Seller before or by any
     court, administrative agency, arbitrator or governmental body;

                                      62
<PAGE>

               (64) No action, inaction, or event has occurred and no state of
     fact exists or has existed that has resulted or will result in the
     exclusion from, denial of, or defense to coverage under any applicable
     hazard insurance policy, irrespective of the cause of such failure of
     coverage. In connection with the placement of any such insurance, no
     commission, fee, or other compensation has been or will be received by
     CHL or any designee of CHL or any corporation in which CHL or any
     officer, director, or employee had a financial interest at the time of
     placement of such insurance;

               (65) Each Mortgage Loan has a fully assignable life of loan tax
     service contract which may be assigned without the payment of any fee;

               (66) No Mortgagor has notified CHL or the Master Servicer on
     CHL's behalf, and CHL has no knowledge, of any relief requested or
     allowed to a Mortgagor under the Relief Act;

               (67) Each Mortgage Loan was originated by a savings and loan
     association, savings bank, commercial bank, credit union, insurance
     company, or mortgage banking company which is supervised and examined by
     a federal or state authority, or by a mortgagee approved by the Secretary
     of Housing and Urban Development pursuant to Sections 2.03 and 2.11 of
     the National Housing Act;

               (68) Each Mortgage Loan was (A) originated no earlier than six
     months prior to the time the applicable Seller purchased such Mortgage
     Loan pursuant to a mortgage loan purchase agreement or other similar
     agreement and (B) underwritten or reunderwritten by the applicable Seller
     in accordance with the applicable Seller's underwriting guidelines in
     effect at the time the loan was underwritten or reunderwritten, as
     applicable;

               (69) Each Mortgage Loan, at the time it was originated and as
     of the Closing Date or the Subsequent Transfer Date, complied in all
     material respects with applicable local, state and federal laws,
     including, but not limited to, all predatory and abusive lending laws;

               (70) None of the Mortgage Loans is a "high cost" mortgage loan
     as defined by applicable federal, state and local predatory and abusive
     lending laws;

               (71) Each Prepayment Charge is enforceable and was originated
     in compliance with all applicable federal, state and local laws;

               (72) None of the Mortgage Loans that are secured by property

     originated on or after March 7, 2003, which is a "high cost home loan" as
     defined under the Georgia Fair Lending Act;

               (74) No Mortgage Loan in the Trust Fund is a High Cost Loan or
     Covered Loan, as applicable (as such terms are defined in the then
     current Standard &

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

               (75) Each Mortgage Loan is secured by a "single family
     residence" within the meaning of Section 25(e)(10) of the Internal
     Revenue Code of 1986 (as amended) (the "Code"). The fair market value of
     the manufactured home securing each Mortgage Loan was at least equal to
     80% of the adjusted issue price of the contract at either (i) the time
     the contract was originated (determined pursuant to the REMIC Provisions)
     or (ii) the time the contract is transferred to the purchaser. Each
     Mortgage Loan is a "qualified mortgage" under Section 860G(a)(3) of the
     Code.

     or result in a material default under, the terms of any other material
     agreement or instrument to which Park Monaco is a party or by which it
     may be bound, or (C) constitute a material violation of any statute,
     order or regulation applicable to Park Monaco of any court, regulatory
     body, administrative agency or governmental body having jurisdiction over
     Park Monaco; and Park Monaco is not in breach or violation of any
     material indenture or other material agreement or instrument, or in
     violation of any statute, order or regulation of any court, regulatory
     body, administrative agency or governmental body having jurisdiction over
     it which breach or violation may materially impair Park Monaco's ability
     to perform or meet any of its obligations under this Agreement.

               (4) No litigation is pending or, to the best of Park Monaco's
     knowledge, threatened, against Park Monaco that would materially and
     adversely affect the execution, delivery or enforceability of this
     Agreement or any Subsequent Transfer Agreement or the ability of Park
     Monaco to sell the Park Monaco Mortgage Loans or to perform any of its
     other obligations under this Agreement or any Subsequent Transfer
     Agreement in accordance with the terms hereof or thereof.

               (5) No consent, approval, authorization or order of any court
     or governmental agency or body is required for the execution, delivery
     and performance by Park Monaco of, or compliance by Park Monaco with,
     this Agreement or any Subsequent Transfer Agreement or the consummation
     of the transactions contemplated hereby, or if any such consent,
     approval, authorization or order is required, Park Monaco has obtained
     the same.

               (6) Park Monaco will treat the transfer of the Park Monaco
     Mortgage Loans to the Depositor as a sale of the Park Monaco Mortgage
     Loans for all tax, accounting and regulatory purposes.

               (7) Immediately prior to the assignment of each Park Monaco
     Mortgage Loan to the Depositor, Park Monaco had good title to, and was
     the sole owner of, such Park Monaco Mortgage Loan free and clear of any
     pledge, lien, encumbrance or security interest and had full right and
     authority, subject to no interest or participation of, or agreement with,
     any other party, to sell and assign the same pursuant to this Agreement.

          (d)     Park Sienna hereby represents and warrants to the Depositor
and the Trustee as follows, as of the Cut-off Date:

     Sienna Mortgage Loan is located or is otherwise not required under
     applicable law to effect such qualification and, in any event, is in
     compliance with the doing business laws of any such state, to the extent
     necessary to ensure its ability to enforce each Park Sienna Mortgage
     Loan, to sell the Park Sienna Mortgage Loans in accordance with the terms

     delivery and performance of this Agreement and each Subsequent Transfer
     Agreement; and this Agreement and each Subsequent Transfer Agreement,
     assuming the due authorization, execution and delivery hereof by the
     other parties hereto, constitutes a legal, valid and binding obligation
     of Park Sienna, enforceable against Park Sienna in accordance with its
     terms, except that (a) the enforceability hereof may be limited by
     bankruptcy, insolvency, moratorium, receivership and other similar laws
     relating to creditors' rights generally and (b) the remedy of specific
     performance and injunctive and other forms of equitable relief may be
     subject to equitable defenses and to the discretion of the court before
     which any proceeding therefor may be brought.

               (3) The execution and delivery of this Agreement and each
     Subsequent Transfer Agreement by Park Sienna, the sale of the Park Sienna
     Mortgage Loans by Park Sienna under this Agreement and each Subsequent
     Transfer Agreement, the consummation of any other of the transactions
     contemplated by this Agreement and each Subsequent Transfer Agreement and
     the fulfillment of or compliance with the terms hereof are in the
     ordinary course of business of Park Sienna and will not (A) result in a
     material breach of any term or provision of the certificate of formation
     or limited liability company agreement of Park Sienna or (B) materially
     conflict with, result in a material breach, violation or acceleration of,
     or result in a material default under, the terms of any other material

     violation of any statute, order or regulation of any court, regulatory
     body, administrative agency or governmental body having jurisdiction over
     it which breach or violation may materially impair Park Sienna's ability
     to perform or meet any of its obligations under this Agreement.

               (4) No litigation is pending or, to the best of Park Sienna's
     knowledge, threatened, against Park Sienna that would materially and
     adversely affect the execution, delivery or enforceability of this

     Sienna to sell the Park Sienna Mortgage Loans or to perform any of its
     other obligations under this Agreement or any Subsequent Transfer
     Agreement in accordance with the terms hereof or thereof.

<PAGE>

               (5) No consent, approval, authorization or order of any court
     or governmental agency or body is required for the execution, delivery
     and performance by Park Sienna of, or compliance by Park Sienna with,
     this Agreement or any Subsequent Transfer Agreement or the consummation
     of the transactions contemplated hereby, or if any such consent,
     approval, authorization or order is required, Park Sienna has obtained
     the same.

               (6) Park Sienna will treat the transfer of the Park Sienna
     Mortgage Loans to the Depositor as a sale of the Park Sienna Mortgage
     Loans for all tax, accounting and regulatory purposes.

               (7) Immediately prior to the assignment of each Park Sienna
     Mortgage Loan to the Depositor, Park Sienna had good title to, and was
     the sole owner of, such the Park Sienna Mortgage Loan free and clear of
     any pledge, lien, encumbrance or security interest and had full right and
     authority, subject to no interest or participation of, or agreement with,
     any other party, to sell and assign the same pursuant to this Agreement.

          (e)     Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) through (d) that
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, the party discovering such breach shall give prompt notice
thereof to the other parties and the NIM Insurer. Each of the Master Servicer
and the Sellers (each, a "Representing Party") hereby covenants with respect
to the representations and warranties set forth in Sections 2.03(a) through
(d) that within 90 days of the earlier of the discovery by such Representing
Party or receipt of written notice by such Representing Party from any party
of a breach of any representation or warranty set forth herein made that
materially and adversely affects the interests of the Certificateholders in
any 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
Replacement 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 that (a) any such substitution pursuant to (i) above or
repurchase pursuant to (ii) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, (b)
any such substitution pursuant to (i) above shall not be effected prior to the
additional delivery to the Trustee of a Request for File Release and (c) any
such substitution pursuant to (i) above shall include a payment by the
applicable Representing Party of any amount as calculated under item (iii) of
the definition of "Purchase Price". Any Representing Party liable for a breach
under this Section 2.03 shall promptly reimburse the Master Servicer or the
Trustee for any expenses reasonably incurred by the Master Servicer or the
Trustee in respect of enforcing the remedies for such breach. To enable the
Master Servicer to amend the Mortgage Loan Schedule, any Representing Party
liable for a breach under this Section 2.03 shall, unless it cures such breach
in a timely fashion pursuant to this Section 2.03, promptly notify the Master
Servicer whether such Representing Party intends either to repurchase, or to
substitute for, the Mortgage Loan affected by such breach. With respect to the
representations and warranties described in this Section that are made to the
best of the Representing Party's knowledge, if it is discovered by any of the
Depositor, the Master Servicer, the Sellers or the Trustee that the substance
of such

                                      67
<PAGE>

representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan, notwithstanding the
Representing Party'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.

          With respect to any Replacement Mortgage Loan or Loans, the
applicable Seller delivering such Replacement Mortgage Loan shall deliver to
the Trustee for the benefit of the Certificateholders the related Mortgage
Note, Mortgage and 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 will be
made in any calendar month after the Determination Date for such month.
Scheduled Payments due with respect to Replacement Mortgage Loans in the Due
Period related to the Distribution Date on which such proceeds are to be
distributed shall not be part of the Trust Fund and will be retained by the
applicable Seller delivering such Replacement Mortgage Loan on such
Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for the related Due Period and thereafter the applicable 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 Replacement Mortgage Loan or Loans
and the Master Servicer shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Replacement Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the
applicable Seller delivering such Replacement Mortgage Loan shall be deemed to
have made with respect to such Replacement Mortgage Loan or Loans, as of the
date of substitution, the representations and warranties set forth in Section
2.03(b), (c) or (d) 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 Co-Trustee shall release to the Representing
Party the Mortgage File relating to such Deleted Mortgage Loan and held for
the benefit of the Certificateholders and shall execute and deliver at the
Master Servicer's direction such instruments of transfer or assignment as have
been prepared by the Master Servicer, in each case without recourse, as shall
be necessary to vest in the applicable Seller, or its respective designee,
title to the Trustee's interest in any Deleted Mortgage Loan substituted for
pursuant to this Section 2.03.

          For any month in which any Seller substitutes one or more
Replacement 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 such Replacement Mortgage Loans as of the date of substitution
is less than the Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) of all such
Deleted Mortgage Loans. An amount equal to the aggregate of the deficiencies
described in the preceding sentence (such amount, the "Substitution Adjustment
Amount") shall be forwarded by the applicable Seller to the Master Servicer
and deposited by the Master Servicer into the Certificate Account not later
than the Determination Date for the Distribution Date relating to the
Prepayment Period during which the related Mortgage Loan became required to be
purchased or replaced hereunder.

                                      68
<PAGE>

          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 the Determination Date for the Distribution Date
in the month following the month during which such Seller became obligated 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, if
any, and the receipt of a Request for File Release, the Co-Trustee shall
release the related Mortgage File held for the benefit of the
Certificateholders to such Seller, and the Trustee shall execute and deliver
at such Person's direction the related instruments of transfer or assignment
prepared by such Seller, in each case without recourse, as shall be necessary
to transfer title from the Trustee for the benefit of the Certificateholders
and transfer the Trustee's interest to such Seller to any Mortgage Loan
purchased pursuant to this Section 2.03. It is understood and agreed that the
obligation under this Agreement of the Sellers to cure, repurchase or replace
any Mortgage Loan as to which a breach has occurred and is continuing shall
constitute the sole remedy against the Sellers respecting such breach
available to Certificateholders, the Depositor or the Trustee.

          (f)     The representations and warranties set forth in this Section
2.03 shall survive delivery of the respective Mortgage Files to the Co-Trustee
for the benefit of the Certificateholders with respect to each Mortgage Loan.

          Section 2.04  Representations and Warranties of the Depositor.
                        ------------------------------------------------

          The Depositor hereby represents and warrants to the Master Servicer
and the Trustee as follows, as of the date hereof and as of each Subsequent
Transfer Date:

               (1) The Depositor is duly organized and is validly existing as
     a corporation in good standing under the laws of the State of Delaware
     and has full power and authority (corporate and other) necessary to own
     or hold its properties and to conduct its business as now conducted by it
     and to enter into and perform its obligations under this Agreement and
     each Subsequent Transfer Agreement.

               (2) The Depositor has the full corporate power and authority to
     execute, deliver and perform, and to enter into and consummate the
     transactions contemplated by, this Agreement and each Subsequent Transfer
     Agreement and has duly authorized, by all necessary corporate action on
     its part, the execution, delivery and performance of this Agreement and
     each Subsequent Transfer Agreement; and this Agreement and each
     Subsequent Transfer Agreement, assuming the due authorization, execution
     and delivery hereof by the other parties hereto, constitutes a legal,
     valid and binding obligation of the Depositor, enforceable against the
     Depositor in accordance with its terms, subject, as to enforceability, to
     (i) bankruptcy, insolvency, reorganization, moratorium and other similar
     laws affecting creditors' rights generally and (ii) general principles of
     equity, regardless of whether enforcement is sought in a proceeding in
     equity or at law.

               (3) The execution and delivery of this Agreement and each
     Subsequent Transfer Agreement by the Depositor, the consummation of the
     transactions contemplated by this Agreement, and the fulfillment of or
     compliance with the terms

                                      69
<PAGE>

     hereof are in the ordinary course of business of the Depositor and will
     not (A) result in a material breach of any term or provision of the
     charter or by-laws of the Depositor or (B) materially conflict with,
     result in a material breach, violation or acceleration of, or result in a
     material default under, the terms of any other material agreement or
     instrument to which the Depositor is a party or by which it may be bound
     or (C) constitute a material violation of any statute, order or
     regulation applicable to the Depositor of any court, regulatory body,
     administrative agency or governmental body having jurisdiction over the
     Depositor; and the Depositor is not in breach or violation of any
     material indenture or other material agreement or instrument, or in
     violation of any statute, order or regulation of any court, regulatory
     body, administrative agency or governmental body having jurisdiction over
     it which breach or violation may materially impair the Depositor's
     ability to perform or meet any of its obligations under this Agreement.

               (4) No litigation is pending, or, to the best of the
     Depositor's knowledge, threatened, against the Depositor that would
     materially and adversely affect the execution, delivery or enforceability
     of this Agreement or any Subsequent Transfer Agreement or the ability of
     the Depositor to perform its obligations under this Agreement or any
     Subsequent Transfer Agreement in accordance with the terms hereof or
     thereof.

               (5) No consent, approval, authorization or order of any court
     or governmental agency or body is required for the execution, delivery
     and performance by the Depositor of, or compliance by the Depositor with,
     this Agreement or any Subsequent Transfer Agreement or the consummation
     of the transactions contemplated hereby, or if any such consent,
     approval, authorization or order is required, the Depositor has obtained
     the same.

          The Depositor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the Closing Date or the related Subsequent
Transfer Date, as applicable, following the transfer of the Mortgage Loans to
it by the Sellers, the Depositor had good title to the Initial Mortgage Loans
or related Subsequent Mortgage Loans, as applicable, and the related Mortgage
Notes were subject to no offsets, claims, defenses or counterclaims.

          It is understood and agreed that the representations and warranties
set forth in the two immediately preceding paragraphs shall survive delivery
of the Mortgage Files to the Co-Trustee. Upon discovery by the Depositor or
the Trustee, of a breach of any of the foregoing representations and
warranties set forth in the immediately preceding paragraph (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. The Depositor hereby covenants with respect to the representations
and warranties made by it in this Section 2.04 that within 90 days of the
earlier of the discovery it or receipt of written notice by it from any party
of a breach of any representation or warranty set forth herein made that
materially and adversely affects the interests of the Certificateholders in
any Mortgage Loan, it shall cure such breach in all material respects and, if
such breach is not so cured, shall repurchase or replace the affected Mortgage
Loan or Loans in accordance with the procedure set forth in Section 2.03(e).

                        -------------------------------------------------
                        Substitutions and Repurchases.
                        ------------------------------

          (a)     Notwithstanding any contrary provision of this Agreement, with
respect to any Mortgage Loan that is not in default or as to which default is
not imminent, no repurchase or substitution pursuant to Sections 2.02, 2.03 or
2.04 shall be made unless the Representing Party making such repurchase or
substitution delivers to the Trustee an Opinion of Counsel (which such
Representing Party shall use reasonable efforts to obtain), addressed to the
Trustee to the effect that such repurchase or substitution would not (i)
result in the imposition of the tax on "prohibited transactions" of the Trust
Fund or contributions after the Closing Date, as defined in sections
860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause the any REMIC
formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding. Any Mortgage Loan as to which repurchase or
substitution was delayed pursuant to this paragraph shall be repurchased or
the substitution therefor shall occur (subject to compliance with Sections
2.02, 2.03 or 2.04) upon the earlier of (a) the occurrence of a default or
imminent default with respect to such loan and (b) receipt by the Trustee of
an Opinion of Counsel to the effect that such repurchase or substitution, as
applicable, will not result in the events described in clause (i) or clause
(ii) of the preceding sentence.

          (b)     Upon discovery by the Depositor, any 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 Business
Days of discovery) give written notice thereof to the other parties and the NIM
Insurer. In connection therewith, the Trustee shall require CHL, at CHL's
option, to either (i) substitute, if the conditions in Section 2.03(e) with
respect to substitutions are satisfied, a Replacement 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 contained in Section 2.03. The Trustee
shall reconvey to CHL the Mortgage Loan to be released pursuant hereto 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  Authentication 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,
authenticated and delivered, to or upon the order of the Depositor, the
Certificates in authorized denominations evidencing 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
best of its ability, to the end that the interests of the Holders of the
Certificates may be adequately and effectively protected.

          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

          (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 the 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 customary
and usual standards of practice of prudent mortgage loan lenders in the
respective states in which the Mortgaged Properties are located, including
taking all required and appropriate actions under each Required Insurance
Policy and taking all required and appropriate actions under the Mortgage
Insurance Policy on behalf of the Co-Trustee, other than the payment of the
Mortgage Insurance Premium and obtaining the approval of the Mortgage Insurer
with respect to the appointment of a successor servicer. 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 hereof, subject to the terms hereof (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, other Liquidation Proceeds and Subsequent Recoveries and (iv)
subject to Section 3.12(b), to effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing any Mortgage Loan; provided
that the Master Servicer shall take no action that is inconsistent with or
prejudices the interests of the Trustee or the Certificateholders in any
Mortgage Loan or the rights and interests of the Depositor and the Trustee
under this Agreement. The Master Servicer shall represent and protect the
interest of the Trustee in the same manner as it currently protects its own
interest 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 term of any Mortgage Loan which would
(i) cause any REMIC formed hereunder to fail to qualify as a REMIC, (ii)
result in the imposition of any tax under section 860(a) or 860(d) of the Code
or (iii) cause any Covered Mortgage Loan to not be covered by the Mortgage
Insurance Policy, but in any case the Master Servicer shall not act in any
manner that is a lesser standard than that provided in the first sentence of
this Section 3.01. Without limiting the generality of the foregoing, the
Master Servicer, in its own name or in the

                                      72
<PAGE>

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 any or all of them as are necessary or appropriate to enable the Master
Servicer to service and administer the Mortgage Loans. 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.

          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. All 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 Balance under the related Mortgage Loans, notwithstanding
that the terms of such Mortgage Loans so permit.

          The Master Servicer shall deliver a list of Servicing Officers to
the Trustee by the Closing Date.

          In addition, the Master Servicer shall administer the Mortgage
Insurance Policy on behalf of itself, the Sellers, the Depositor, and the
Trustee for the benefit of the Certificateholders, when it is necessary to
make claims and receive payments under the Mortgage Insurance Policy. 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 the
Certificateholders, claims to the insurer under any primary insurance policies
and, in this regard, to take any reasonable action 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.

          The Master Servicer shall take whatever action is appropriate to
maximize the amounts payable under the Mortgage Insurance Policy and to
service the Covered Mortgage Loans in the manner required by the Mortgage
Insurance Policy. The Master Servicer shall prepare and submit all claims
eligible for submission under the Mortgage Insurance Policies and shall
perform all of the obligations of the insured under the Mortgage Insurance
Policy. If the

                                      73
<PAGE>

Mortgage Insurance Policy is terminated for any reason other than the
exhaustion of its coverage, or if the financial strength rating of its issuer
is reduced to below investment grade, the Master Servicer will use its best
efforts to obtain a comparable policy from an insurer that is acceptable to
the Rating Agencies. The replacement policy will provide coverage equal to the
then remaining coverage of the applicable Mortgage Insurance Policy, if
available. However, if the premium cost of a replacement policy exceeds the
premium cost of the Mortgage Insurance Policy, the coverage amount of the
replacement policy will be reduced so that its premium cost will not exceed
the premium cost of the Mortgage Insurance Policy.

          In the event that a shortfall in any collection on or liability with
respect to any Mortgage Loan results from or is attributable to adjustments to
Mortgage Rates, Scheduled Payments or Stated Principal Balances that were made
by the Master Servicer in a manner not consistent with the terms of the
related Mortgage Note and this Agreement, the Master Servicer, upon discovery
or receipt of notice thereof, immediately shall deliver to the Trustee for
deposit in the Distribution Account from its own funds the amount of any such
shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee,
the Depositor and any successor master servicer in respect of any such
liability. Such indemnities shall survive the termination or discharge of this
Agreement. Notwithstanding the foregoing, this Section 3.01 shall not limit
the ability of the Master Servicer to seek recovery of any such amounts from
the related Mortgagor under the terms of the related Mortgage Note, as
permitted by law and shall not be an expense of the Trust.

                        ------------------------------------------------------
                        Servicer.
                        ---------

          (a)     The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided that (i)
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 hereunder, (ii) that
such subservicing agreements would not result in a withdrawal or a downgrading
by any Rating Agency of the ratings on any Class of Certificates, as evidenced
by a letter to that effect delivered by each Rating Agency to the Depositor
and the NIM Insurer and (iii) the NIM Insurer shall have consented to such
subservicing agreements (which consent shall not be unreasonably withheld)
with Subservicers, for the servicing and administration of the Mortgage Loans.
The Master Servicer shall deliver to the Trustee copies of all Sub-Servicing
Agreements, and any amendments or modifications thereof, promptly upon the
Master Servicer's execution and delivery of such instruments. The Master
Servicer, with the written consent of the NIM Insurer (which consent shall not
be unreasonably withheld), shall be entitled to terminate any Subservicing
Agreement and the rights and obligations of any Subservicer pursuant to any
Subservicing Agreement in accordance with the terms and conditions of such
Subservicing Agreement. Notwithstanding the provisions of any subservicing
agreement, any of the provisions of this Agreement relating to agreements or
arrangements between the Master Servicer or a subservicer or reference to
actions taken through a Master Servicer 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

                                      74
<PAGE>

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. Every subservicing agreement entered into by the Master Servicer shall
contain a provision giving the successor Master Servicer the option to
terminate such agreement without cost in the event a successor Master Servicer
is appointed. 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 Sellers, the
                        -----------------------------------------
                        Certificateholders, the NIM Insurer and the Trustee in
                        ------------------------------------------------------
                        Respect of the Master Servicer.
                        -------------------------------

          None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer or the Depositor shall have any responsibility or liability for any
action or failure to act by the Master Servicer, and none of them is obligated
to supervise the performance of the Master Servicer hereunder or otherwise.
The Master Servicer shall afford (and any Subservicing Agreement shall provide
that each Subservicer shall afford) the Depositor, the NIM Insurer and the
Trustee, upon reasonable notice, during normal business hours, access to all
records maintained by the Master Servicer (and any such Subservicer) in
respect of the Master Servicer's rights and obligations hereunder and access
to officers of the Master Servicer (and those of any such Subservicer)
responsible for such obligations. Upon request, the Master Servicer shall
furnish to the Depositor, the NIM Insurer and the Trustee its (and any such
Subservicer's) most recent financial statements and such other information
relating to the Master Servicer's capacity to perform its obligations under
this Agreement that it possesses. To the extent such information is not
otherwise available to the public, the Depositor, the NIM Insurer and the
Trustee shall not disseminate any information obtained pursuant to the
preceding two sentences without the Masters Servicer's (or any such
Subservicer's) written consent, except as required pursuant to this Agreement
or to the extent that it is necessary to do so (i) in working with legal
counsel, auditors, taxing authorities or other governmental agencies, rating
agencies or reinsurers or (ii) pursuant to any law, rule, regulation, order,
judgment, writ, injunction or decree of any court or governmental authority
having jurisdiction over the Depositor, the Trustee, the NIM Insurer or the
Trust Fund, and in either case, the Depositor, the NIM Insurer or the Trustee,
as the case may be, shall use its reasonable best efforts to assure the
confidentiality of any such disseminated non-public information. 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 or exercise the rights of the Master Servicer under this
Agreement; provided by virtue of such performance by the Depositor of its
designee. The Depositor shall not have any responsibility or liability for any
action or failure to act by the Master Servicer and is not 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 hereunder (including by reason of an Event of Default),
the Trustee or its designee shall thereupon assume all of the rights and
obligations of the Master Servicer hereunder arising thereafter (except that
the Trustee shall not be (i) liable for losses of the Master Servicer pursuant
to Section 3.10 hereof or any acts or omissions of the predecessor Master
Servicer hereunder, (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 hereunder, including pursuant to Section 2.02
or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant
to Section 2.03 or (v) deemed to have made any representations and warranties
hereunder, including pursuant to Section 2.03 or the first paragraph of
Section 6.02 hereof). If the Master Servicer shall for any reason no longer be
the Master Servicer (including by reason of any Event of Default), the Trustee
(or any other successor servicer) may, at its option, succeed to any rights
and obligations of the Master Servicer under any subservicing agreement in
accordance with the terms thereof; provided that the Trustee (or any other
successor servicer) shall not incur any liability or have any obligations in
its capacity as servicer under a subservicing agreement arising prior to the
date of such succession unless it expressly elects to succeed to the rights
and obligations of the Master Servicer thereunder; and the Master Servicer
shall not thereby be relieved of any liability or obligations under the
subservicing agreement arising prior to the date of such succession.

          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 and the Mortgage Loans
then being serviced thereunder and an accounting of amounts collected held by
it and otherwise use its best efforts to effect the orderly and efficient
transfer of the subservicing agreement to the assuming party.

          Section 3.05  Collection of Mortgage Loan Payments; Certificate
                        -------------------------------------------------

                        Account; Seller Shortfall Interest Requirement.
                        -----------------------------------------------

          (a)     The Master Servicer shall make reasonable efforts in
accordance with customary and usual standards of practice of prudent mortgage
lenders in the respective states in which the Mortgaged Properties are located
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 270 days. In the event of any such arrangement,
the Master Servicer shall make Advances on the related Mortgage Loan 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 have
been granted such waivers or extensions exceeds 5% of the aggregate number of
Initial

                                      76
<PAGE>

Mortgage Loans and Subsequent 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
on a daily basis within two Business Days of receipt, except as otherwise
specifically provided herein, 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 hereunder:

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

               (2) all payments on account of interest on the Mortgage Loans
     (net of the related Servicing Fee and Prepayment Interest Excess
     permitted under Section 3.15 hereof to the extent not previously paid to
     or withheld by the Master Servicer);

               (3) all Insurance Proceeds;

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

               (5) all Compensating Interest;

               (6) any amount required to be deposited by the Master Servicer
     pursuant to Section 3.05(e) in connection with any losses on Permitted
     Investments;

               (7) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.10 hereof;

               (8) the Purchase Price and any Substitution Adjustment Amount;

               (9) all Advances made by the Master Servicer or the Trustee
     pursuant to Section 4.01 hereof;

               (10) all Prepayment Charges and Master Servicer Prepayment
     Charge Payment Amounts; and

               (11) any other amounts required to be deposited hereunder.

          The foregoing requirements for remittance by the Master Servicer
into the Certificate Account shall be exclusive, it being understood and
agreed that, without limiting the

                                      77
<PAGE>

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 and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time withdraw or direct the institution maintaining the
Certificate Account, to withdraw such amount from the Certificate Account, any
provision herein to the contrary notwithstanding. Such withdrawal or direction
may be accomplished by delivering written notice thereof to the institution
maintaining the Certificate Account, that 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.

          No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in each of April 2005, May 2005 and June
2005, CHL shall remit to the Master Servicer, and the Master Servicer shall
deposit in the Certificate Account, the Seller Shortfall Interest Requirement
(if any) for such Master Servicer Advance Date.

          (c)     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 therein the following:

               (1) the aggregate amount remitted by the Master Servicer
     pursuant to the second paragraph of Section 3.08(a); and

               (2) any amount required to be deposited by the Master Servicer
     pursuant to Section 3.05(e) in connection with any losses on Permitted
     Investments.

          The foregoing requirements for remittance by the Master Servicer and
deposit by the Trustee into the Distribution Account shall be exclusive. In
the event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding.
Such direction may be accomplished by delivering a written notice to the
Trustee that 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.

          (d)     The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Pre-Funding Account. On the Closing Date, CHL shall
remit the Pre-Funded Amount to the Trustee for deposit in the Pre-Funding
Account.

          On the Business Day before the Distribution Date following the end
of the Funding Period, the Trustee shall (i) withdraw the amount on deposit in
the Pre-Funding Account (net of investment income), (ii) promptly deposit such
amount in the Distribution

                                      78
<PAGE>

Account, and (iii) distribute each amount to the Certificates on the
Distribution Date pursuant to Section 4.04.

          No later than 1:00 p.m. Pacific time on the Business Day prior to
the Master Servicer Advance Date in April 2005, May 2005 and June 2005, CHL on
behalf of the Sellers shall remit to the Master Servicer, and the Master
Servicer shall deposit in the Certificate Account, the Seller Shortfall
Interest Requirement (if any) for such Master Servicer Advance Date.

          (e)     Each institution that maintains the Certificate Account, the
Distribution Account or the Pre-Funding Account shall invest the funds in each
such account, as directed by the Master Servicer, in Permitted Investments,
which shall mature not later than (x) in the case of the Certificate 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 Certificate Account, then such Permitted
Investment shall mature not later than the Business Day next preceding such
Distribution Account Deposit Date) and (y) in the case of the Distribution
Account and the Pre-Funding Account, 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 such Distribution Account or Pre-Funding Account, then such
Permitted Investment shall mature not later than such Distribution Date), 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. In the case of (i) the Certificate Account
and the Distribution Account, all income and gain net of any losses realized
from any such investment shall be for the benefit of the Master Servicer as
servicing compensation and shall be remitted to it monthly as provided herein
and (ii) the Pre-Funding Account, all income and gain net of any losses
realized from any such investment shall be for the benefit of CHL and shall be
remitted to CHL as provided herein. The amount of any losses incurred in the
Certificate Account or the Distribution Account in respect of any such
investments shall be deposited by the Master Servicer in the Certificate
Account or paid to the Trustee for deposit into the Distribution Account out
of the Master Servicer's own funds immediately as realized. The amount of any
losses incurred in the Pre-Funding Account in respect of any such investments
shall be paid by CHL to the Trustee for deposit into the Pre-Funding Account
out of CHL's own funds 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 Certificate Account, the Distribution
Account or the Pre-Funding Account and made in accordance with this Section
3.05.

          (f)     The Master Servicer shall give at least 30 days advance notice
to the Trustee, each Seller, each Rating Agency and the Depositor of any
proposed change of location of the Certificate Account prior to any change
thereof. The Trustee shall give at least 30 days advance 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 or
the Carryover Reserve Fund prior to any change thereof.

          (g)     Except as otherwise expressly provided in this Agreement, if
any default occurs under any Permitted Investment, the Trustee may and, subject
to Sections 8.01 and 8.02(a)(4), at the request of the Holders of Certificates
representing more than 50% of the Voting

payment or performance, including the institution and prosecution of
appropriate proceedings.

                        Escrow Accounts.
                        ----------------

          To the extent required by the related Mortgage Note, 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 herein shall require the Master Servicer to compel a
Mortgagor to establish an Escrow Account in violation of applicable law.

          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 hereof (with respect to taxes and assessments and
insurance premiums) and 3.10 hereof (with respect to hazard insurance), to
refund to any Mortgagors any sums as may be 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 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

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

          The Master Servicer shall afford the Depositor, the NIM Insurer and
the Trustee reasonable access to all records and documentation regarding the
Mortgage Loans and all accounts, insurance policies 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 offices of the
Master Servicer designated by it. Upon request, the Master Servicer 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.

          Upon reasonable advance notice in writing if required by federal
regulation, the Master Servicer will provide to each Certificateholder or
Certificate Owner that 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 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 or Certificate Owner for actual expenses incurred by the
Master Servicer in providing such reports and access.

          (a)     The Master Servicer may from time to time make withdrawals
from the Certificate Account for the following purposes:

                  (i)   to pay to the Master Servicer (to the extent not
          previously paid to or withheld by the Master Servicer), as servicing
          compensation in accordance with Section 3.15, that portion of any
          payment of interest that equals the Servicing Fee for the period with
          respect to which such interest payment was made, and, as additional
          servicing compensation to the Master Servicer, those other amounts
          set forth in Section 3.15;

                  (ii)  to reimburse each of the Master Servicer and the Trustee
          for Advances made by it with respect to the Mortgage Loans, such
          right of reimbursement pursuant to this subclause (ii) being limited
          to amounts received on particular Mortgage Loan(s) (including, for
          this purpose, Liquidation Proceeds, Insurance Proceeds and Subsequent
          Recoveries) that represent late recoveries of payments of principal
          and/or interest on such particular Mortgage Loan(s) in respect of
          which any such Advance was made;

                  (iii) [Reserved];

                  (iv)  to reimburse each of the Master Servicer and the Trustee
          for any Nonrecoverable Advance previously made;

                  (v)   to reimburse the Master Servicer from Insurance Proceeds
          for Insured Expenses covered by the related Insurance Policy;

                  (vi)  to pay the Master Servicer any unpaid Servicing Fees and
          to reimburse it for any unreimbursed Servicing Advances, the Master
          Servicer's right to reimbursement of Servicing Advances pursuant to
          this subclause (vi) with respect to any Mortgage Loan being limited
          to amounts received on particular Mortgage Loan(s) (including, for
          this purpose, Liquidation Proceeds, Insurance Proceeds and Subsequent
          Recoveries and purchase and repurchase proceeds) that represent late
          recoveries of the payments for which such advances were made pursuant
          to Section 3.01 or Section 3.06;

                  (vii) to pay to the applicable Seller, the Depositor or the
          Master Servicer, as applicable, with respect to each Mortgage Loan or
          property acquired in respect thereof that has been purchased pursuant
          to Section 2.02, 2.03, 2.04 or 3.12, all amounts received thereon and
          not taken into account in determining the related Stated Principal
          Balance of such repurchased Mortgage Loan;

                  (viii) to reimburse the applicable Seller, the Master
          Servicer, the NIM Insurer or the Depositor for expenses incurred by
          any of them in connection with the Mortgage Loans or Certificates and
          reimbursable pursuant to Section 6.03 hereof; provided that such
          amount shall only be withdrawn following the

                                      81
<PAGE>

          withdrawal from the Certificate Account for deposit into the
          Distribution Account pursuant to the following paragraph;

                 (ix) to pay any lender-paid primary mortgage insurance
          premiums;

                  (x)   to withdraw any amount deposited in the Certificate
          Account and not required to be deposited therein; and

                  (xi)  to clear and terminate the Certificate Account upon
          termination of this Agreement pursuant to Section 9.01 hereof.

          In addition, no later than 1:00 p.m. Pacific time on the Distribution
Account Deposit Date, the Master Servicer shall withdraw from the Certificate
Account and remit to the Trustee the Interest Remittance Amount and Principal
Remittance Amount, and the Trustee shall deposit such amount in the
Distribution Account.

          The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On the
Closing Date, CHL shall deposit into the Principal Reserve Fund $200.00. Funds
on deposit in the Principal Reserve Fund shall not be invested. The Principal
Reserve Fund shall be treated as an "outside reserve fund" under applicable
Treasury regulations and shall not be part of any REMIC created under this
Agreement.

          On the Business Day before the first Distribution Date, the Trustee
shall transfer $100.00 from the Principal Reserve Fund to the Distribution
Account, and on the first Distribution Date, the Trustee shall withdraw $100
and distribute such amount to the Class A-R Certificates in reduction of the
Certificate Principal Balance thereof.

          On the Business Day before the Class P Principal Distribution Date,
the Trustee shall transfer from the Principal Reserve Fund to the Distribution
Account $100 and shall distribute such amount to the Class P Certificates on
the Class P Principal Distribution Date. Following the distributions to be made
in accordance with the preceding sentence, the Trustee shall then terminate the
Principal Reserve Fund.

          The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to subclauses (i), (ii), (iv),
(v), (vi), (vii) and (viii) above. Prior to making any withdrawal from the
Certificate Account pursuant to subclause (iv), the Master Servicer shall
deliver to the Trustee an Officer's Certificate of a Servicing Officer
indicating the amount of any previous Advance determined by the Master Servicer
to be a Nonrecoverable Advance and identifying the related Mortgage Loan(s),
and their respective portions of such Nonrecoverable Advance.

          (b)     The Trustee shall withdraw funds from the Distribution Account
for distribution to the Certificateholders in the manner specified in this
Agreement (and to withhold from the amounts so withdrawn, the amount of any
taxes that it is authorized to retain pursuant to the penultimate paragraph of
Section 8.11). In addition, the Trustee may from time to time make withdrawals
from the Distribution Account for the following purposes:

                  (i)   to pay the Trustee the Trustee Fee on each Distribution
          Date;

          compensation, earnings on or investment income with respect to funds
          in or credited to the Distribution Account;

                  (iii) to withdraw pursuant to Section 3.05 any amount
          deposited in the Distribution Account and not required to be
          deposited therein;

                  (iv)  to reimburse the Trustee for any unreimbursed Advances
          made by it pursuant to Section 4.01(d) hereof, such right of
          reimbursement pursuant to this subclause (iv) being limited to (x)
          amounts received on the related Mortgage Loan(s) in respect of which
          any such Advance was made and (y) amounts not otherwise reimbursed to
          the Trustee pursuant to Section 3.08(a)(ii) hereof;

                  (v)   to reimburse the Trustee for any Nonrecoverable Advance
          previously made by the Trustee pursuant to Section 4.01(d) hereof,
          such right of reimbursement pursuant to this subclause (v) being
          limited to amounts not otherwise reimbursed to the Trustee pursuant
          to Section 3.08(a)(iv) hereof; and

                  (vi)  to pay to the Co-Trustee, for payment to the Mortgage
          Insurer as provided below, the Mortgage Insurance Premium;

                  (vii) to clear and terminate the Distribution Account upon
          termination of the Agreement pursuant to Section 9.01 hereof.

          The Co-Trustee shall pay the applicable Mortgage Insurance Premium to
the Mortgage Insurer in accordance with the following wiring instructions:

          (c)     The Trustee shall withdraw funds from the Carryover Reserve
Fund for distribution to the Certificateholders in the manner specified in this
Agreement (and to withhold from the amounts so withdrawn, the amount of any
taxes that it is authorized to retain pursuant to the penultimate paragraph of
Section 8.11). In addition, the Trustee may from time to time make withdrawals

          Section 3.09 [Reserved]

          Section 3.10 Maintenance of Hazard Insurance.

          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 and (ii) the greater of (a) the outstanding
principal balance of the Mortgage Loan and (b) an amount such that the proceeds
of such policy shall be sufficient to prevent the related Mortgagor and/or
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. The Master Servicer shall also cause flood insurance
to be maintained on property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan, to the extent described below. Pursuant to
Section 3.05 hereof, 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 property thus acquired 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 Liquidation Proceeds or
Subsequent Recoveries to the extent permitted by Section 3.08 hereof. 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 lesser of (i) the
original principal balance of the related Mortgage Loan, (ii) the replacement
value of the improvements that are part of such Mortgaged Property, or (iii)
the maximum amount of such insurance available for the related Mortgaged
Property under the Flood Disaster Protection Act of 1973, as amended.

          Section 3.11  Enforcement of Due-On-Sale Clauses; Assumption
                        ----------------------------------------------
                        Agreements.
                        -----------

          (a)     Except as otherwise provided in this Section 3.11(a), when
any property subject to a Mortgage has been or is about to be 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

                                      84
<PAGE>

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-sale clause, or if coverage
under any Required Insurance Policy would be adversely affected, or if
nonenforcement is otherwise permitted hereunder, the Master Servicer is
authorized, subject to Section 3.11(b), to take or enter into an assumption and
modification agreement from or with the person to whom such property has been
or is about to be conveyed, pursuant to which such person becomes liable under
the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor
remains liable thereon, provided that the Mortgage Loan shall continue to be
covered (if so covered before the Master Servicer enters such agreement) by the
applicable Required Insurance Policies. The Master Servicer, subject to Section
3.11(b), is also authorized with the prior approval of the insurers under any
Required Insurance Policies to enter into a substitution of liability agreement
with such Person, pursuant to which the original Mortgagor is released from
liability and such Person is substituted as Mortgagor and becomes liable under
the Mortgage Note. The Master Servicer shall notify the Trustee that any such
substitution, modification or assumption agreement has been completed by
forwarding to the Co-Trustee the executed original of such substitution or
assumption agreement, which document shall be added to the related Mortgage
File and shall, for all purposes, be considered a part of such Mortgage File to
the same extent as all other documents and instruments constituting a part
thereof.

          (b)     Subject to the Master Servicer's duty to enforce any
due-on-sale clause to the extent set forth in Section 3.11(a) hereof, in any
case in which a Mortgaged Property has been conveyed to a Person by a
Mortgagor, and such Person is to enter into an assumption agreement or
modification agreement or supplement to the Mortgage Note or Mortgage that
requires the signature of the Trustee, or if an instrument of release signed by
the Trustee is required releasing the Mortgagor from liability on the Mortgage
Loan, the Master Servicer shall prepare and deliver or cause to be prepared and
delivered to the Trustee for signature and shall direct, in writing, the
Trustee to execute the assumption agreement with the Person to whom the
Mortgaged Property is to be conveyed and such modification agreement or
supplement to the Mortgage Note or Mortgage or other instruments as are
reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage
or otherwise to comply with any applicable laws regarding assumptions or the
transfer of the Mortgaged Property to such Person. In connection with any such
assumption, no material term of the Mortgage Note (including, but not limited
to, the Mortgage Rate, the amount of the Scheduled Payment, the Maximum
Mortgage Rate, the Minimum Mortgage Rate, the Gross Margin, the Initial
Periodic Rate Cap, the Subsequent Periodic Rate Cap, the Adjustment Date and
any other term affecting the amount or timing of payment on the Mortgage Loan)
may be changed. In addition, the substitute Mortgagor and the Mortgaged
Property must be acceptable to the Master Servicer in accordance with its
underwriting standards as then in effect. The Master Servicer shall notify the
Trustee that any such substitution or assumption agreement has been completed
by forwarding to the Trustee the original of such substitution or assumption
agreement, which in the case of the original shall be added to the related
Mortgage File and shall, for all purposes, be considered a part of such
Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. Any fee collected by the Master Servicer for
entering into an assumption or substitution of liability agreement will be
retained by the Master Servicer as additional servicing compensation.

          Section 3.12  Realization Upon Defaulted Mortgage Loans;
                        ------------------------------------------
                        Determination of Excess Proceeds and Realized Losses;
                        -----------------------------------------------------
                        Repurchase of Certain Mortgage Loans.
                        -------------------------------------

          (a)     The Master Servicer may agree to a modification of any
Mortgage Loan (the "Modified Mortgage Loan") if (i) the modification is in lieu
of a refinancing and (ii) the Mortgage Rate on the Modified Mortgage Loan is
approximately a prevailing market rate for newly-originated mortgage loans
having similar terms and (iii) the Master Servicer purchases the Modified
Mortgage Loan from the Trust Fund as described below. Effective immediately
after the modification, and, in any event, on the same Business Day on which
the modification occurs, all interest of the Trustee in the Modified Mortgage
Loan shall automatically be deemed transferred and assigned to the Master
Servicer and all benefits and burdens of ownership thereof, including the right
to accrued interest thereon from the date of modification and the risk of
default thereon, shall pass to the Master Servicer. The Master Servicer shall
promptly deliver to the Trustee a certification of a Servicing Officer to the
effect that all requirements of this paragraph have been satisfied with respect
to the Modified Mortgage Loan. For federal income tax purposes, the Trustee
shall account for such purchase as a prepayment in full of the Modified
Mortgage Loan. The Master Servicer shall deposit the Purchase Price for any
Modified Mortgage Loan in the Certificate Account pursuant to Section 3.05
within one Business Day after the purchase of the Modified Mortgage Loan. Upon
receipt by the Trustee of written notification of any such deposit signed by a
Servicing Officer, the Trustee shall release to the Master Servicer the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as shall be necessary to vest in the
Master Servicer any Modified Mortgage Loan previously transferred and assigned
pursuant hereto. The Master Servicer covenants and agrees to indemnify the
Trust Fund against any liability for any "prohibited transaction" taxes and any
related interest, additions, and penalties imposed on the Trust Fund
established hereunder as a result of any modification of a Mortgage Loan
effected pursuant to this subsection (b), any holding of a Modified Mortgage
Loan by the Trust Fund or any purchase of a Modified Mortgage Loan by the
Master Servicer (but such obligation shall not prevent the Master Servicer or
any other appropriate Person from in good faith contesting any such tax in
appropriate proceedings and shall not prevent the Master Servicer from
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings). The Master Servicer shall have no right of reimbursement for
any amount paid pursuant to the foregoing indemnification, except to the extent
that the amount of any tax, interest, and penalties, together with interest
thereon, is refunded to the Trust Fund or the Master Servicer. If the Master
Servicer agrees to a modification of any Mortgage Loan pursuant to this Section
3.12(a), and if such Mortgage Loan carries a Prepayment Charge provision, the
Master Servicer will deliver to the Trustee the amount of the Prepayment
Charge, if any, that would have been due had such Mortgage Loan been prepaid at
the time of such modification, for deposit into the Certificate Account (not
later than 1:00 p.m. Pacific time on the Master Servicer Advance Date
immediately succeeding the date of such modification) for distribution in
accordance with the terms of this Agreement.

          (b)     The Master Servicer shall use reasonable efforts to foreclose
upon or otherwise comparably convert the ownership of properties securing such
of the Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion,

                                      86
<PAGE>

the Master Servicer shall follow such practices and procedures as it shall deem
necessary or advisable and as shall be normal and usual in its general mortgage
servicing activities and the requirements of the insurer under any Required
Insurance Policy; provided that the Master Servicer shall not be required to
expend its own funds in connection with any foreclosure or towards the
restoration of any property unless it shall determine (i) that such restoration
and/or foreclosure will increase the proceeds of liquidation of the Mortgage
Loan after reimbursement to itself of such expenses and (ii) that such expenses
will be recoverable to it through Liquidation Proceeds (respecting which it
shall have priority for purposes of withdrawals from the Certificate Account
pursuant to Section 3.08 hereof). The Master Servicer shall be responsible for
all other costs and expenses incurred by it in any such proceedings; provided
that it shall be entitled to reimbursement thereof from the proceeds of
liquidation of the related Mortgaged Property and any related Subsequent
Recoveries, as contemplated in Section 3.08 hereof. If the Master Servicer has
knowledge that a Mortgaged Property that the Master Servicer is contemplating
acquiring in foreclosure or by deed-in-lieu of foreclosure is located within a
one-mile radius of any site with environmental or hazardous waste risks known
to the Master Servicer, the Master Servicer will, prior to acquiring the
Mortgaged Property, consider such risks and only take action in accordance with
its established environmental review procedures.

          With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such
REO Property solely as the Trustee hereunder and not in its individual
capacity. The Master Servicer shall ensure that the title to such REO Property
references this Agreement and the Trustee's capacity thereunder. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall either itself
or through an agent selected by the Master Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO Property is located and may, incident to its
conservation and protection of the interests of the Certificateholders, rent
the same, or any part thereof, as the Master Servicer deems to be in the best
interest of the Master Servicer and the Certificateholders for the period prior
to the sale of such REO Property. The Master Servicer shall prepare for and
deliver to the Trustee a statement with respect to each REO Property that has
been rented showing the aggregate rental income received and all expenses
incurred in connection with the management and maintenance of such REO Property
at such times as is necessary to enable the Trustee to comply with the
reporting requirements of the REMIC Provisions. The net monthly rental income,
if any, from such REO Property shall be deposited in the Certificate Account no
later than the close of business on each Determination Date. The Master
Servicer shall perform the tax reporting and withholding related to
foreclosures, abandonments and cancellation of indebtedness income as specified
by Sections 1445, 6050J and 6050P of the Code by preparing and filing such tax
and information returns, as may be required.

          In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that maximizes the Liquidation Proceeds, but in
no event later than three years after its acquisition by the Trust Fund or, at
the expense of the Trust Fund, the Master Servicer shall request, more than 60
days prior to the day on which such three-year period would otherwise expire,
an extension of the three-year grace period. In the event the Trustee shall
have been supplied with an Opinion of

                                      87
<PAGE>

Counsel (such opinion not to be an expense of the Trustee) to the effect that
the holding by the Trust Fund of such Mortgaged Property subsequent to such
three-year period will not result in the imposition of taxes on "prohibited
transactions" of the Trust Fund as defined in section 860F of the Code or cause
any REMIC formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding, and the Trust Fund may continue to hold such
Mortgaged Property (subject to any conditions contained in such Opinion of
Counsel) after the expiration of such three-year period. Notwithstanding any
other provision of this Agreement, no Mortgaged Property acquired by the Trust
Fund shall be rented (or allowed to continue to be rented) or otherwise used
for the production of income by or on behalf of the Trust Fund in such a manner
or pursuant to any terms that would (i) cause such Mortgaged Property to fail
to qualify as "foreclosure property" within the meaning of section 860G(a)(8)
of the Code or (ii) subject the Trust Fund to the imposition of any federal,
state or local income taxes on the income earned from such Mortgaged Property
under section 860G(c) of the Code or otherwise, unless the Master Servicer has
agreed to indemnify and hold harmless the Trust Fund with respect to the
imposition of any such taxes.

          The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of
bringing such a proceeding. The income earned from the management of any
Mortgaged Properties acquired through foreclosure or other judicial proceeding,
net of reimbursement to the Master Servicer for expenses incurred (including
any property or other taxes) in connection with such management and net of
unreimbursed Servicing Fees, Advances, Servicing Advances and any management
fee paid or to be paid with respect to the management of such Mortgaged
Property, shall be applied to the payment of principal of, and interest on, the
related defaulted Mortgage Loans (with interest accruing as though such
Mortgage Loans were still current) and all such income shall be deemed, for all
purposes in this Agreement, to be payments on account of principal and interest
on the related Mortgage Notes and shall be deposited into the Certificate
Account. To the extent the income received during a Prepayment Period is in
excess of the amount attributable to amortizing principal and accrued interest
at the related Mortgage Rate on the related Mortgage Loan, such excess shall be
considered to be a partial Principal Prepayment for all purposes hereof.

          The Liquidation Proceeds from any liquidation of a Mortgage Loan and
any Subsequent Recoveries, net of any payment to the Master Servicer as
provided above, shall be deposited in the Certificate Account as provided in
Section 3.05 for distribution on the related Distribution Date, except that any
Excess Proceeds shall be retained by the Master Servicer as additional
servicing compensation.

          The proceeds of any Liquidated Mortgage Loan, as well as any recovery
resulting from a partial collection of Liquidation Proceeds or any income from
an REO Property, will be applied in the following order of priority: first, to
reimburse the Master Servicer for any related unreimbursed Servicing Advances
and Servicing Fees, pursuant to Section 3.08(a)(vi) or this Section 3.12;
second, to reimburse the Master Servicer for any unreimbursed Advances,
pursuant to Section 3.08(a)(ii) or this Section 3.12; third, to accrued and
unpaid interest (to the extent no Advance has been made for such amount) on the
Mortgage Loan or related REO Property, at the Net Mortgage Rate to the Due Date
occurring in the month in which such amounts are required to be distributed;
and fourth, as a recovery of principal of the Mortgage Loan.

<PAGE>

          (c)     [Reserved]

          (d)     The Master Servicer, in its sole discretion, shall have the
right to elect (by written notice sent to the Trustee) to purchase for its own
account from the Trust Fund any Mortgage Loan that is 150 days or more
delinquent at a price equal to the Purchase Price; provided, however, that the
Master Servicer may only exercise this right on or before the last day of the
calendar month in which such Mortgage Loan became 150 days delinquent (such
month, the "Eligible Repurchase Month"); provided further, that any such
Mortgage Loan which becomes current but thereafter becomes delinquent may be
purchased by the Master Servicer pursuant to this Section in any ensuing
Eligible Repurchase Month. The Purchase Price for any Mortgage Loan purchased
hereunder shall be deposited in the Certificate Account. Any purchase of a
Mortgage Loan pursuant to this Section 3.12(d) shall be accomplished by
remittance to the Master Servicer for deposit in the Certificate Account of the
Purchase Price. The Trustee, upon receipt of certification from the Master
Servicer of such deposit and a Request for File Release from the Master
Servicer, shall release or cause to be released to the purchaser of such
Mortgage Loan the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the purchaser of such
Mortgage Loan, in each case without recourse, as shall be necessary to vest in
the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto
and the purchaser of such Mortgage Loan shall succeed to all the Trustee's
right, title and interest in and to such Mortgage Loan and all security and
documents related thereto. Such assignment shall be an assignment outright and
not for security. The purchaser of such Mortgage Loan shall thereupon own such
Mortgage Loan, and all security and documents, free of any further obligation
to the Trustee or the Certificateholders with respect thereto.

          Section 3.13  Co-Trustee to Cooperate; Release of Mortgage Files.
                        ---------------------------------------------------

          Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, the Master Servicer will promptly notify
the Co-Trustee by delivering a Request for File Release. Upon receipt of such
request, the Co-Trustee shall promptly release the related Mortgage File to the
Master Servicer, and the Co-Trustee shall at the Master Servicer's direction
execute and deliver to the Master Servicer the request for reconveyance, deed
of reconveyance or release or satisfaction of mortgage or such instrument
releasing the lien of the Mortgage in each case provided by the Master
Servicer, together with the Mortgage Note with written evidence of cancellation
thereon. The Master Servicer is authorized to cause the removal from the
registration on the MERS(R) System of such Mortgage and to execute and deliver,
on behalf of the Trust Fund and the Certificateholders or any of them, any and
all instruments of satisfaction or cancellation or of partial or full release.
No expenses incurred in connection with any instrument of satisfaction or deed
of reconveyance shall be chargeable to the Certificate Account, the
Distribution Account, the Carryover Reserve Fund or the related subservicing
account. From time to time and as shall be appropriate for the servicing or
foreclosure of any Mortgage Loan, including for such purpose, collection under
any policy of flood insurance any fidelity bond or errors or omissions policy,
or for the purposes of effecting a partial release of any Mortgaged Property
from the lien of the Mortgage or the making of any corrections to the Mortgage
Note or the Mortgage or any of the other documents included in the Mortgage
File, the Co-Trustee shall, upon delivery to the Co-Trustee of a Request for
Document Release or a Request for File

                                      89

Mortgage File, as the case may be, to the Master Servicer. Subject to the
further limitations set forth below, the Master Servicer shall cause the
Mortgage File or documents so released to be returned to the Co-Trustee when
the need therefor by the Master Servicer no longer exists, unless the Mortgage
Loan is liquidated and the proceeds thereof are deposited in the Certificate
Account, in which case the Master Servicer shall deliver to the Co-Trustee a
Request for File Release for any remaining documents in the Mortgage File not
in the possession of the Master Servicer.

          If the Master Servicer at any time seeks to initiate a foreclosure

any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity. Notwithstanding the foregoing, the
Master Servicer shall cause possession of any Mortgage File or of the documents
therein that shall have been released by the Co-Trustee to be returned to the
Co-Trustee within 21 calendar days after possession thereof shall have been
released by the Co-Trustee unless (i) the Mortgage Loan has been liquidated and
the Liquidation Proceeds relating to the Mortgage Loan have been deposited in
the Certificate Account, and the Master Servicer shall have delivered to the
Co-Trustee a Request for File Release or (ii) the Mortgage File or document
shall have been delivered to an attorney or to a public trustee or other public
official as required by law for purposes of initiating or pursuing legal action
or other proceedings for the foreclosure of the Mortgaged Property and the

a Servicing Officer certifying as to the name and address of the Person to
which the Mortgage File or the documents therein were delivered and the purpose
or purposes of such delivery.

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

          Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Co-Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise are
collected by the Master Servicer as Liquidation Proceeds, Insurance Proceeds or
Subsequent Recoveries in respect of any Mortgage Loan. All Mortgage Files and
funds collected or held by, or under the control of, the Master Servicer in
respect of any Mortgage Loans, whether from the collection of principal and
interest payments or from Liquidation Proceeds or Subsequent Recoveries,
including but not limited to, any funds on deposit in the Certificate Account,
shall be held by the Master Servicer for and on behalf of the Trust Fund and
shall be and remain the sole and exclusive property of the Trust Fund, subject
to the applicable provisions of this Agreement. The Master Servicer also agrees
that it shall not create, incur or subject any Mortgage File or any funds that
are deposited in the Certificate Account, the Distribution Account, the
Carryover Reserve Fund or in any Escrow Account (as defined in Section 3.06),
or any funds that otherwise are or may become due or payable to the Trustee for
the benefit of the Certificateholders, to any claim, lien, security interest,
judgment, levy, writ of

attachment or other encumbrance, or assert by legal action or otherwise any
claim or right of set off against any Mortgage File or any funds collected on,
or in connection with, a Mortgage Loan, except, however, that the Master
Servicer shall be entitled to set off against and deduct from any such funds
any amounts that are properly due and payable to the Master Servicer under this
Agreement.

          Section 3.15  Servicing Compensation.
                        -----------------------

          As compensation for its activities hereunder, the Master Servicer
shall be entitled to retain or withdraw from the Certificate Account out of
each payment of interest on a Mortgage Loan included in the Trust Fund an
amount equal to interest at the applicable Servicing Fee Rate on the Stated
Principal Balance of the related Mortgage Loan for the period covered by such
interest payment.

          Additional servicing compensation in the form of any Excess Proceeds,
assumption fees, late payment charges, Prepayment Interest Excess, and all
income and gain net of any losses realized from Permitted Investments shall be
retained by the Master Servicer to the extent not required to be deposited in
the Certificate Account pursuant to Section 3.05 or 3.12(b) hereof. The Master
Servicer shall be required to pay all expenses incurred by it in connection
with its servicing activities hereunder (including payment of any premiums for
hazard insurance, as required by Section 3.10 hereof and maintenance of the
other forms of insurance coverage required by Section 3.10 hereof) and shall
not be entitled to reimbursement therefor except as specifically provided in
Sections 3.08 and 3.12 hereof.

          Section 3.16  Access to Certain Documentation.
                        --------------------------------

          The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates and
Certificate Owners and the examiners and supervisory agents of the OTS, the
FDIC and such other authorities, access to the documentation regarding the
Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such
access shall be afforded without charge, but only upon reasonable and prior
written request and during normal business hours at the offices of the Master
Servicer designated by it. Nothing in this Section shall limit the obligation
of the Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer to
provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section.

          Section 3.17  Annual Statement as to Compliance.
                        ----------------------------------

          The Master Servicer shall deliver to the Depositor and the Trustee on
or before the 80th day after the end of the Master Servicer's fiscal year,
commencing with its 2005 fiscal year, an Officer's Certificate stating, as to
the signer thereof, that (i) a review of the activities of the Master Servicer

Servicer under this Agreement has been made under such officer's supervision
and (ii) to the best of such officer's knowledge, based on such review, the
Master Servicer has fulfilled all its obligations under this Agreement
throughout such year, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default known to such officer and the

                                      91
<PAGE>

nature and status thereof and (iii) to the best of such officer's knowledge,
each Subservicer has fulfilled all its obligations under its Subservicing
Agreement throughout such year, or, if there has been a default in the
fulfillment of any such obligation specifying each such default known to such
officer and the nature and status thereof. The Trustee shall forward a copy of
each such statement to each Rating Agency. Copies of such statement shall be
provided by the Trustee to any Certificateholder or Certificate Owner upon
request at the Master Servicer's expense, provided such statement is delivered
by the Master Servicer to the Trustee.

          Section 3.18  Annual Independent Public Accountants' Servicing

                        Statement; Financial Statements.
                        --------------------------------

          On or before the later of (i) the 80th day after the end of the
Master Servicer's fiscal year, commencing with its 2005 fiscal year or (ii)
within 30 days of the issuance of the annual audited financial statements
beginning with the audit for the period ending in 2005, the Master Servicer at
its expense shall cause a nationally recognized firm of independent public
accountants (who may also render other services to the Master Servicer, CHL or
any affiliate thereof) that is a member of the American Institute of Certified
Public Accountants to furnish a report to the Trustee, the Depositor and CHL in
compliance with the Uniform Single Attestation Program for Mortgage Bankers.
Copies of such report shall be provided by the Trustee to any Certificateholder
or Certificate Owner upon request at the Master Servicer's expense, provided
such report is delivered by the Master Servicer to the Trustee. Upon written
request, the Master Servicer shall provide to the Certificateholders or
Certificate Owners its publicly available annual financial statements (or the
Master Servicer's parent company's publicly available annual financial
statements, as applicable), if any, promptly after they become available.

          Section 3.19  The Corridor Contract.
                        ----------------------

          CHL shall cause The Bank of New York to enter into the Corridor
Contract Administration Agreement and shall assign all of its right, title and
interest in and to the interest rate corridor transaction evidenced by the
Corridor Contract to, and shall cause all of its obligations in respect of such
transactions to be assumed by, the Corridor Contract Administrator pursuant to,
and on the terms and conditions set forth in, the Corridor Contract Assignment
Agreement. The Trustee's rights to receive certain proceeds of the Corridor
Contract as provided in the Corridor Contract Administration Agreement will be
an asset of the Trust Fund but will not be an asset of any REMIC. The Trustee
shall deposit any amounts received from time to time with respect to the
Corridor Contract into the Carryover Reserve Fund. The Master Servicer shall
deposit any amounts received on behalf of the Trustee from time to time with
respect to the Corridor Contract into the Carryover Reserve Fund.

          No later than two Business Days following each Distribution Date, the
Trustee shall provide the Corridor Contract Administrator with information
regarding the aggregate Certificate Principal Balance of the Interest-Bearing
Certificates after all distributions on such Distribution Date.

          The Trustee shall direct the Corridor Contract Administrator to
terminate the Corridor Contract upon the occurrence of certain events of
default or termination events to the extent specified thereunder. Upon any such
termination, the Corridor Contract Counterparty will

                                      92
<PAGE>

be obligated to pay the Corridor Contract Administrator an amount in respect of
such termination, and the portion of such amount that is distributable to the
Trust Fund pursuant to the Corridor Contract Administration Agreement and
received by the Trustee or the Master Servicer for the benefit of the Trust
Fund, as the case may be, in respect of such termination shall be deposited and
held in the Carryover Reserve Fund to pay Net Rate Carryover for the applicable
Classes of Certificates as provided in Section 4.04(e) on the Distribution
Dates following such termination to and including the Corridor Contract
Termination Date, but shall not be available for distribution to the Class C
Certificates pursuant to Section 4.08(c) until the Corridor Contract
Termination Date. On the Corridor Contract Termination Date, after all other
distributions on such date, if any amounts in respect of early termination of
the Corridor Contract remain in the Carryover Reserve Fund, such amounts shall
be distributed by the Trustee to the Class C Certificates.

          Section 3.20  Prepayment Charges.
                        -------------------

          (a)     Notwithstanding anything in this Agreement to the contrary,
in the event of a Principal Prepayment in full or in part of a Mortgage Loan,
the Master Servicer may not waive any Prepayment Charge or portion thereof
required by the terms of the related Mortgage Note unless (i) such Mortgage
Loan is in default or the Master Servicer believes that such default is
imminent and the Master Servicer determines that such waiver would maximize
recovery of Liquidation Proceeds for such Mortgage Loan, taking into account
the value of such Prepayment Charge, or (ii) (A) the enforceability thereof is
limited (1) by bankruptcy, insolvency, moratorium, receivership, or other
similar law relating to creditors' rights generally or (2) due to acceleration
in connection with a foreclosure or other involuntary payment, or (B) the
enforceability is otherwise limited or prohibited by applicable law. In the
event of a Principal Prepayment in full or in part with respect to any Mortgage
Loan, the Master Servicer shall deliver to the Trustee an Officer's Certificate
substantially in the form of Exhibit T no later than the third Business Day
following the immediately succeeding Determination Date with a copy to the
Class P Certificateholders. If the Master Servicer has waived or does not
collect all or a portion of a Prepayment Charge relating to a Principal
Prepayment in full or in part due to any action or omission of the Master
Servicer, other than as provided above, the Master Servicer shall deliver to
the Trustee, together with the Principal Prepayment in full or in part, the
amount of such Prepayment Charge (or such portion thereof as had been waived)
for deposit into the Certificate Account (not later than 1:00 p.m. Pacific time
on the immediately succeeding Master Servicer Advance Date, in the case of such
Prepayment Charge) for distribution in accordance with the terms of this
Agreement.

          (b)     Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing subsection (a), the party
discovering the breach shall give prompt written notice to the other parties.

          (c)     CHL represents and warrants to the Depositor and the Trustee,
as of the Closing Date and each Subsequent Transfer Date, that the information
in the Prepayment Charge Schedule (including the attached prepayment charge
summary) is complete and accurate in all material respects at the dates as of
which the information is furnished and each Prepayment Charge is permissible
and enforceable in accordance with its terms under applicable state law,

                                      93
<PAGE>

except as the enforceability thereof is limited due to acceleration in
connection with a foreclosure or other involuntary payment.

          (d)     Upon discovery by the Master Servicer or a Responsible
Officer of the Trustee of a breach of the foregoing clause (c) that materially
and adversely affects right of the Holders of the Class P Certificates to any
Prepayment Charge, the party discovering the breach shall give prompt written
notice to the other parties. Within 60 days of the earlier of discovery by the
Master Servicer or receipt of notice by the Master Servicer of breach, the
Master Servicer shall cure the breach in all material respects or shall pay
into the Certificate Account the amount of the Prepayment Charge that would
otherwise be due from the Mortgagor, less any amount representing such
Prepayment Charge previously collected and paid by the Master Servicer into the
Certificate Account.

                                  ARTICLE IV.
               DISTRIBUTIONS AND ADVANCES BY THE MASTER SERVICER

          Section 4.01  Advances; Remittance Reports.
                        -----------------------------

          (a)     Within two Business Days after each Determination Date, the
Master Servicer shall deliver to the Trustee by facsimile or electronic mail
(or by such other means as the Master Servicer and the Trustee, as the case may
be, may agree from time to time) a Remittance Report with respect to the
related Distribution Date. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Master Servicer.

          (b)     Subject to the conditions of this Article IV, the Master
Servicer, as required below, shall make an Advance and deposit such Advance in
the Certificate Account. Each such Advance shall be remitted to the Certificate
Account no later than 1:00 p.m. Pacific time on the Master Servicer Advance
Date in immediately available funds. The Trustee will provide notice to the
Master Servicer by facsimile by the close of business on any Master Servicer
Advance Date in the event that the amount remitted by the Master Servicer to
the Trustee on the Distribution Account Deposit Date is less than the Advances
required to be made by the Master Servicer for such Distribution Date. The
Master Servicer shall be obligated to make any such Advance only to the extent
that such advance would not be a Nonrecoverable Advance. If the Master Servicer
shall have determined that it has made a Nonrecoverable Advance or that a
proposed Advance or a lesser portion of such Advance would constitute a
Nonrecoverable Advance, the Master Servicer shall deliver (i) to the Trustee
for the benefit of the Certificateholders funds constituting the remaining
portion of such Advance, if applicable, and (ii) to the Depositor, each Rating
Agency and the Trustee an Officer's Certificate setting forth the basis for
such determination.

          (c)     In lieu of making all or a portion of such Advance from its
own funds, the Master Servicer may (i) cause to be made an appropriate entry in
its records relating to the Certificate Account that any Amount Held for Future
Distributions has been used by the Master Servicer in discharge of its
obligation to make any such Advance and (ii) transfer such funds from the
Certificate Account to the Distribution Account. Any funds so applied and
transferred shall be replaced by the Master Servicer by deposit in the
Certificate Account no later than the

                                      94
<PAGE>

close of business on the Business Day immediately preceding the Distribution
Date on which such funds are required to be distributed pursuant to this
Agreement. The Master Servicer shall be entitled to be reimbursed from the
Certificate Account for all Advances of its own funds made pursuant to this
Section as provided in Section 3.08. The obligation to make Advances with
respect to any Mortgage Loan shall continue until such Mortgage Loan is paid in
full or the related Mortgaged Property or related REO Property has been
liquidated or until the purchase or repurchase thereof (or substitution
therefor) from the Trustee pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section 4.01.

         (d)      If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to give
written notice thereof to the Trustee (each such notice a "Trustee Advance
Notice"; and such notice may be given by facsimile), not later than 3:00 p.m.,
New York time, on the Business Day immediately preceding the related Master
Servicer Advance Date, specifying the amount that it will be unable to deposit
(each such amount an "Advance Deficiency") and certifying that such Advance
Deficiency constitutes an Advance hereunder and is not a Nonrecoverable
Advance. If the Trustee receives a Trustee Advance Notice on or before 3:30
p.m., (New York time) on a Master Servicer Advance Date, the Trustee shall, not
later than 3:00 p.m., (New York time), on the related Distribution Date,
deposit in the Distribution Account an amount equal to the Advance Deficiency
identified in such Trustee Advance Notice unless it is prohibited from so doing
by applicable law. Notwithstanding the foregoing, the Trustee shall not be
required to make such deposit if the Trustee shall have received written
notification from the Master Servicer that the Master Servicer has deposited or
caused to be deposited in the Certificate Account an amount equal to such
Advance Deficiency. All Advances made by the Trustee pursuant to this Section
4.01(d) shall accrue interest on behalf of the Trustee at the Trustee Advance
Rate from and including the date such Advances are made to but excluding the
date of repayment, with such interest being an obligation of the Master
Servicer and not the Trust Fund. The Master Servicer shall reimburse the
Trustee for the amount of any Advance made by the Trustee pursuant to this
Section 4.01(d) together with accrued interest, not later than 6:00 p.m. (New
York time) on the Business Day following the related Distribution Date. In the
event that the Master Servicer does not reimburse the Trustee in accordance
with the requirements of the preceding sentence, the Trustee shall immediately
(i) terminate all of the rights and obligations of the Master Servicer under
this Agreement in accordance with Section 7.01 and (ii) subject to the
limitations set forth in Section 3.04, assume all of the rights and obligations
of the Master Servicer hereunder.

          (e)     On or before 5:00 p.m. Pacific time on the fifth Business Day
following each Determination Date (but in no event later than 5:00 p.m. Pacific
time on the third Business Day before the related Distribution Date) the Master
Servicer shall deliver to the Trustee a report (in form and substance
reasonably satisfactory to the Trustee) that indicates (i) the Mortgage Loans
with respect to which the Master Servicer has determined that the related
Scheduled Payments should be advanced and (ii) the amount of the related
Scheduled Payments. The Master Servicer shall deliver to the Trustee on the
related Master Servicer Advance Date an Officer's Certificate of a Servicing
Officer indicating the amount of any proposed Advance determined by the Master
Servicer to be a Nonrecoverable Advance.

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

          In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall, the Master Servicer shall remit any related Compensating
Interest as part of the related Interest Remittance Amount as provided in this
Agreement. The Master Servicer shall not be entitled to any recovery or
reimbursement for Compensating Interest from the Depositor, the Trustee, any
Seller, the Trust Fund or the Certificateholders.

          set forth in clause (3) below, until the Certificate Principal

          Balance of the Class A Certificates is greater than the aggregate
          Stated Principal Balance of the Mortgage Loans, any principal amounts

          case until the Certificate Principal Balance thereof is reduced to
          zero, and not as described above.

          (c)     [Reserved].

the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the name
of a Depository shall be made to such Depository in immediately available
funds.

          (a)     On the Closing Date, the Trustee shall establish and maintain
in its name, in trust for the benefit of the Holders of the Certificates, the
Carryover Reserve Fund and shall deposit $10,000 therein. 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.

          (b)     On each Distribution Date, the Trustee shall deposit all
amounts received in respect of the Corridor Contract in the Carryover Reserve
Fund. The Trustee shall make withdrawals from the Carryover Reserve Fund to
make distributions in respect of Net Rate Carryover as to the extent required
by Section 4.04.

          (c)     Any amounts received on the Corridor Contract with respect to
a Distribution Date and remaining after the distributions required pursuant to
Section 4.04(e) shall

                                      104

be distributed to the Class C Certificates; provided, however, that if the
Corridor Contract is subject to early termination, early termination payments
received in respect of the Corridor Contract shall be deposited by the Trustee
in the Carryover Reserve Fund and withdrawn from the Carryover Reserve Fund to
pay any Net Rate Carryover on the related Classes of Certificates as provided
in Section 4.04(e) on the Distribution Dates following such termination to and
including the Corridor Contract Termination Date, but such early termination
payments shall not be available for distribution to the Class C Certificates on
future Distribution Dates until the Corridor Contract Termination Date.

          (d)     Funds in the Carryover Reserve Fund in respect of amounts
received in respect of the Corridor Contract may be invested in Permitted
Investments at the direction of the Majority Holder of the Class C Certificates
(voting as a single Class), 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 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 Certificateholders. In the absence of such written direction, all funds
in the Carryover Reserve Fund in respect of amounts received of under the
Corridor Contract shall be invested by the Trustee in The Bank of New York cash
reserves. Any net investment earnings on such amounts shall be payable pro rata
to the Holders of the Class C Certificates in accordance with their Percentage
Interests. 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.

          (e)     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 4.08. The

hereunder. The Class C Certificates shall evidence ownership of the Carryover
Reserve Fund for federal tax purposes.

          The Certificates shall be executed by manual or facsimile signature
on behalf of the Trustee by an authorized officer. Certificates bearing the
manual or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall bind
the Trustee, notwithstanding that such individuals or any of them have ceased
to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such authentication
and delivery. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such
Certificate a certificate of authentication substantially in the form set forth
as attached hereto executed by the Trustee by manual signature, and such
certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. On the Closing Date, the Trustee shall authenticate
the Certificates to be issued at the written direction of the Depositor, or any
affiliate thereof.

          The Depositor shall provide, or cause to be provided, to the Trustee
on a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

          Section 5.02  Certificate Register; Registration of Transfer and
                        --------------------------------------------------
                        Exchange of Certificates.
                        -------------------------

          (a)     The Trustee shall maintain a Certificate Register for the
Trust Fund in which, subject to the provisions of subsections (b) and (c) below
and to such reasonable regulations as it may prescribe, the Trustee shall
provide for the registration of Certificates and of Transfers and exchanges of
Certificates as herein provided. Upon surrender for registration of Transfer of
any Certificate, the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

          At the option of a Certificateholder, Certificates may be exchanged
for other Certificates of the same Class in authorized denominations and
evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall

                                      106
<PAGE>

execute, authenticate, and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of Transfer or exchange shall be accompanied by a
written instrument of Transfer in form satisfactory to the Trustee duly
executed by the Holder thereof or his attorney duly authorized in writing.

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

          All Certificates surrendered for registration of Transfer or exchange
shall be canceled and subsequently destroyed by the Trustee in accordance with
the Trustee's customary procedures.

          (b)     No Transfer of a Private Certificate shall be made unless
such Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such state securities laws, in order to assure
compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such Certificateholder's
prospective transferee shall (except in connection with any transfer of a
Private Certificate to an affiliate of the Depositor (either directly or
through a nominee) on or about the Closing Date) each certify to the Trustee in
writing the facts surrounding the Transfer in substantially the forms set forth
in Exhibit J-2 and, in the case of a Class A-R Certificate, Exhibit J-1 (each,
a "Transferor Certificate") and (i) deliver a letter in substantially the form
of either Exhibit K (the "Investment Letter") or Exhibit L (the "Rule 144A
Letter") or (ii) there shall be delivered to the Trustee at the expense of the
Certificateholder desiring to effect such transfer an Opinion of Counsel that
such Transfer may be made pursuant to an exemption from the Securities Act;
provided, however, that in the case of the delivery of an Investment Letter in
connection with the transfer of any Class C or Class P Certificate to a
transferee that is formed with the purpose of issuing notes backed by such
Class C or Class P Certificate, as the case may be, clause (b) and (c) of the
form of Investment Letter shall not be applicable and shall be deleted by such
transferee. The Depositor shall provide to any Holder of a Private Certificate
and any prospective transferee designated by any such Holder, information
regarding the related Certificates and the Mortgage Loans and such other
information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for transfer of any such Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee, the Co-Trustee and the Master
Servicer shall cooperate with the Depositor in providing the Rule 144A
information referenced in the preceding sentence, including providing to the
Depositor such information regarding the Certificates, the Mortgage Loans and
other matters regarding the Trust Fund as the Depositor shall reasonably
request to meet its obligation under the preceding sentence. Each Holder of a
Private Certificate desiring to effect such Transfer shall, and does hereby
agree to, indemnify the Trustee, the Co-Trustee, the Depositor, the Trust Fund,
each Seller, the Master Servicer and the NIM Insurer against any liability that
may result if the Transfer is not so exempt or is not made in accordance with
such federal and state laws.

                                      107
<PAGE>

          No Transfer of an ERISA-Restricted Certificate (other than a transfer
of an ERISA-Restricted Certificate to an affiliate of the Depositor (either
directly or through a nominee) on or about the Closing Date) shall be made
unless the Trustee shall have received either (i) a representation from the
transferee of such Certificate acceptable to and in form and substance
satisfactory to the Trustee (in the event such Certificate is a Private
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit
K or Exhibit L, or in the event such Certificate is a Residual Certificate,
such requirement is satisfied only by the Trustee's receipt of a representation
letter from the transferee substantially in the form of Exhibit I), to the
effect that (x) such transferee is not an employee benefit plan or arrangement
subject to Section 406 of ERISA or a plan or arrangement subject to Section
4975 of the Code, or a Person acting on behalf of any such plan or arrangement
or using the assets of any such plan or arrangement, or (y) in the case of an
ERISA-Restricted Certificate that has been the subject of an ERISA-Qualifying
Underwriting, a representation that the transferee is an insurance company
which is purchasing such Certificate with funds contained in an "insurance
company general account" (as such term is defined in section V(e) of Prohibited
Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the purchase and
holding of such Certificate satisfy the requirements for exemptive relief under
Sections I and III of PTCE 95-60 or (ii) in the case of any ERISA-Restricted
Certificate presented for registration in the name of an employee benefit plan
or arrangement subject to ERISA, or a plan or arrangement subject to Section
4975 of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or arrangement or any other person acting on behalf of
any such plan or arrangement, an Opinion of Counsel satisfactory to the
Trustee, addressed to the Trustee and the Master Servicer, to the effect that
the purchase or holding of such ERISA-Restricted Certificate will not result in
a non-exempt prohibited transaction under ERISA or the Code and will not
subject the Trustee or the Master Servicer to any obligation in addition to
those expressly undertaken in this Agreement, which Opinion of Counsel shall
not be an expense of the Trustee, the Master Servicer, or the Trust Fund. For
purposes of the preceding sentence, one of such representations, as
appropriate, shall be deemed to have been made to the Trustee by the
transferee's acceptance of an ERISA-Restricted Certificate (or the acceptance
by a Certificate Owner of the beneficial interest in any such Class of
ERISA-Restricted Certificates) unless the Trustee shall have received from the
transferee an Opinion of Counsel as described in clause (ii) or a
representation letter acceptable in form and substance to the Trustee.
Notwithstanding anything else to the contrary herein, any purported transfer of
an ERISA-Restricted Certificate to or on behalf of an employee benefit plan
subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code
without the delivery to the Trustee of an Opinion of Counsel satisfactory to
the Trustee meeting the requirements of clause (i) of the first sentence of
this paragraph as described above shall be void and of no effect. The Trustee
shall be under no liability to any Person for any registration of transfer of
any ERISA-Restricted Certificate that is in fact not permitted by this Section
5.02(b) or for making any payments due on such Certificate to the Holder
thereof or taking any other action with respect to such Holder under the
provisions of this Agreement so long as the Trustee, with respect to the
transfer of such Classes of Certificates, required delivery of such
certificates and other documentation or evidence as are expressly required by
the terms of this Agreement and examined such certificates and other
documentation or evidence to determine compliance as to form with the express
requirements hereof. The Trustee shall be entitled, but not obligated, to
recover from any Holder of any ERISA-Restricted Certificate that was in fact an
employee

                                      108
<PAGE>

benefit plan or arrangement subject to Section 406 of ERISA or a plan or
arrangement subject to Section 4975 of the Code or a Person acting on behalf of
any such plan or arrangement at the time it became a Holder or, at such
subsequent time as it became such a plan or arrangement or Person acting on
behalf of such a plan or arrangement, all payments made on such
ERISA-Restricted Certificate at and after either such time. Any such payments
so recovered by the Trustee shall be paid and delivered by the Trustee to the
last preceding Holder of such Certificate that is not such a plan or
arrangement or Person acting on behalf of a plan or arrangement.

          (c)     Each Person who has or who acquires any Ownership Interest in
a Class A-R Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the following provisions,
and the rights of each Person acquiring any Ownership Interest in a Class A-R
Certificate are expressly subject to the following provisions:

                  (1) Each Person holding or acquiring any Ownership Interest
          in a Class A-R Certificate shall be a Permitted Transferee and shall
          promptly notify the Trustee of any change or impending change in its
          status as a Permitted Transferee.

                  (2) Except in connection with (i) the registration of the Tax
          Matters Person Certificate in the name of the Trustee or (ii) any
          registration in the name of, or transfer of a Class A-R Certificate
          to, an affiliate of the Depositor (either directly or through a
          nominee) on or about the Closing Date, no Ownership Interest in a
          Class A-R Certificate may be registered or transferred, and the
          Trustee shall not register the Transfer of any Class A-R Certificate,
          unless the Trustee shall have been furnished with an affidavit (a
          "Transfer Affidavit") of the initial owner or the proposed transferee
          in the form attached hereto as Exhibit I.

                  (3) Each Person holding or acquiring any Ownership Interest
          in a Class A-R Certificate shall agree (A) to obtain a Transfer
          Affidavit from any other Person to whom such Person attempts to
          Transfer its Ownership Interest in a Class A-R Certificate, (B) to
          obtain a Transfer Affidavit from any Person for whom such Person is
          acting as nominee, trustee or agent in connection with any Transfer
          of a Class A-R Certificate and (C) not to Transfer its Ownership
          Interest in a Class A-R Certificate, or to cause the Transfer of an
          Ownership Interest in a Class A-R Certificate to any other Person, if
          it has actual knowledge that such Person is not a Permitted
          Transferee or that such Transfer Affidavit is false.

                  (4) Any attempted or purported Transfer of any Ownership
          Interest in a Class A-R Certificate in violation of the provisions of
          this Section 5.02(c) shall be absolutely null and void and shall vest
          no rights in the purported Transferee. If any purported transferee
          shall become a Holder of a Class A-R Certificate in violation of the
          provisions of this Section 5.02(c), then the last preceding Permitted
          Transferee shall be restored to all rights as Holder thereof
          retroactive to the date of registration of Transfer of such Class A-R
          Certificate. The Trustee shall be under no liability to any Person
          for any registration of Transfer of a Class A-R Certificate that is
          in fact not permitted by Section 5.02(b) and this Section 5.02(c) or
          for making any payments due on such Certificate to the Holder thereof
          or taking any other action with respect to such Holder under the
          provisions of this Agreement so long as the Transfer was registered
          after receipt of the

                                      109
<PAGE>

          related Transfer Affidavit and Transferor Certificate. The Trustee
          shall be entitled but not obligated to recover from any Holder of a
          Class A-R Certificate that was in fact not a Permitted Transferee at
          the time it became a Holder or, at such subsequent time as it became
          other than a Permitted Transferee, all payments made on such Class
          A-R Certificate at and after either such time. Any such payments so
          recovered by the Trustee shall be paid and delivered by the Trustee
          to the last preceding Permitted Transferee of such Certificate.

                  (5) The Master Servicer shall use its best efforts to make
          available, upon receipt of written request from the Trustee, all
          information necessary to compute any tax imposed under section
          860E(e) of the Code as a result of a Transfer of an Ownership
          Interest in a Class A-R Certificate to any Holder who is not a
          Permitted Transferee.

          The restrictions on Transfers of a Class A-R Certificate set forth in
this Section 5.02(c) shall cease to apply (and the applicable portions of the
legend on a Class A-R Certificate may be deleted) with respect to Transfers
occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion
of Counsel shall not be an expense of the Trustee, any Seller or the Master
Servicer to the effect that the elimination of such restrictions will not cause
any REMIC formed hereunder to fail to qualify as a REMIC at any time that the
Certificates are outstanding or result in the imposition of any tax on the
Trust Fund, a Certificateholder or another Person. Each Person holding or
acquiring any Ownership Interest in a Class A-R Certificate, by acceptance of
its Ownership Interest, shall be deemed to consent to any amendment of this
Agreement that, based on an Opinion of Counsel furnished to the Trustee, is
reasonably necessary (a) to ensure that the record ownership of, or any
beneficial interest in, a Class A-R Certificate is not transferred, directly or
indirectly, to a Person that is not a Permitted Transferee and (b) to provide
for a means to compel the Transfer of a Class A-R Certificate that is held by a
Person that is not a Permitted Transferee to a Holder that is a Permitted
Transferee.

          (d)     The preparation and delivery of all affidavits,
certifications and opinions referred to above in this section 5.02 shall not be
an expense of the Trust Fund, the Trustee, the Depositor, any Seller or the
Master Servicer.

          Section 5.03  Mutilated, Destroyed, Lost or Stolen Certificates.
                        --------------------------------------------------

          If (a) any mutilated Certificate is surrendered to the Trustee, or
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and of the ownership thereof and (b) there is
delivered to the Master Servicer and the Trustee such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice to the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like Class, tenor and Percentage Interest. In connection with
the issuance of any new Certificate under this Section 5.03, the Trustee may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee) connected therewith. Any
replacement Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if

                                      110
<PAGE>

originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time. All Certificates surrendered to the Trustee under
the terms of this Section 5.03 shall be canceled and destroyed by the Trustee
in accordance with its standard procedures without liability on its part.

          Section 5.04  Persons Deemed Owners.
                        ----------------------

          The Master Servicer, the Trustee and any agent of the Master Servicer
or the Trustee may treat the person in whose name any Certificate is registered
as the owner of such Certificate for the purpose of receiving distributions as
provided in this Agreement and for all other purposes whatsoever, and none of
the Master Servicer, the Trustee or the NIM Insurer or any agent of the Master
Servicer, the Trustee or the NIM Insurer shall be affected by any notice to the
contrary.

          Section 5.05  Access to List of Certificateholders' Names and
                        -----------------------------------------------
                        Addresses.
                        ----------

          If three or more Certificateholders or Certificate Owners (a) request
such information in writing from the Trustee, (b) state that such
Certificateholders or Certificate Owners desire to communicate with other
Certificateholders or Certificate Owners with respect to their rights under
this Agreement or under the Certificates and (c) provide a copy of the
communication that such Certificateholders or Certificate Owners propose to
transmit or if the Depositor or Master Servicer shall request such information
in writing from the Trustee, then the Trustee shall, within ten Business Days
after the receipt of such request, provide the Depositor, the Master Servicer
or such Certificateholders or Certificate Owners at such recipients' expense
the most recent list of the Certificateholders of the Trust Fund held by the
Trustee, if any. The Depositor and every Certificateholder or Certificate
Owner, by receiving and holding a Certificate, agree that the Trustee shall not
be held accountable by reason of the disclosure of any such information as to
the list of the Certificateholders hereunder, regardless of the source from
which such information was derived.

          Section 5.06  Book-Entry Certificates.
                        ------------------------

          The Book-Entry Certificates, upon original issuance, shall be issued
in the form of one typewritten Certificate (or more than one, if required by
the Depository) for each Class of such Certificates, to be delivered to the
Depository by or on behalf of the Depositor. Such Certificates shall initially
be registered on the Certificate Register in the name of the Depository or its
nominee, and no Certificate Owner of such Certificates will receive a
definitive certificate representing such Certificate Owner's interest in such
Certificates, except as provided in Section 5.08. Unless and until definitive,
fully registered Certificates ("Definitive Certificates") have been issued to
the Certificate Owners of such Certificates pursuant to Section 5.08:

          (a)     the provisions of this Section shall be in full force and
effect;

          (b)     the Depositor, the Sellers, the Master Servicer and the
Trustee may deal with the Depository and the Depository Participants for all
purposes (including the making of distributions) as the authorized
representative of the respective Certificate Owners of such Certificates;

                                      111
<PAGE>

          (c)     registration of the Book-Entry Certificates may not be
transferred by the Trustee except to another Depository;

          (d)     the rights of the respective Certificate Owners of such
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of such Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and until
Definitive Certificates are issued pursuant to Section 5.08, the Depository
will make book-entry transfers among the Depository Participants and receive
and transmit distributions of principal and interest on the related
Certificates to such Depository Participants;

          (e)     the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants;

          (f)     the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants; and

          (g)     to the extent the provisions of this Section conflict with
any other provisions of this Agreement, the provisions of this Section shall
control.

          For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of,
Certificateholders evidencing a specified percentage of the aggregate unpaid
principal amount of any Class of Certificates, such direction or consent may be
given by Certificate Owners (acting through the Depository and the Depository
Participants) owning Book-Entry Certificates evidencing the requisite
percentage of principal amount of such Class of Certificates.

          Whenever any notice or other communication is required to be given to
Certificateholders of the Class with respect to which Book-Entry Certificates
have been issued, unless and until Definitive Certificates shall have been
issued to the related Certificate Owners, the Trustee shall give all such
notices and communications to the Depository.

          Section 5.08  Definitive Certificates.
                        ------------------------

          If, after Book-Entry Certificates have been issued with respect to
any Certificates, (a) the Depositor advises the Trustee that the Depository is
no longer willing or able to discharge properly its responsibilities under the
Depository Agreement with respect to such Certificates and the Trustee or the
Depositor is unable to locate a qualified successor or (b) after the occurrence
and continuation of an Event of Default, Certificate Owners of such Book-Entry
Certificates having not less than 51% of the Voting Rights evidenced by any
Class of Book-Entry Certificates advise the Trustee and the Depository in
writing through the Depository Participants that the continuation of a
book-entry system with respect to Certificates of such Class through the
Depository (or its successor) is no longer in the best interests of the
Certificate Owners of such Class, then the Trustee shall notify all Certificate
Owners of such Certificates, through the Depository, of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners of such Class requesting the same. The Depositor shall

                                      112
<PAGE>

provide the Trustee with an adequate inventory of Certificates to facilitate
the issuance and transfer of Definitive Certificates. Upon surrender to the
Trustee of any such Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall
authenticate and deliver such Definitive Certificates. Neither the Depositor
nor the Trustee shall be liable for any delay in delivery of such instructions
and each may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of such Definitive Certificates, all references
herein to obligations imposed upon or to be performed by the Depository shall
be deemed to be imposed upon and performed by the Trustee, to the extent
applicable with respect to such Definitive Certificates and the Trustee shall
recognize the Holders of such Definitive Certificates as Certificateholders
hereunder.

Attention: Corporate Trust MBS Administration, as offices for such purposes.
The Trustee will give prompt written notice to the Certificateholders of any
change in such location of any such office or agency.

          None of the Depositor, the Sellers, the NIM Insurer or the Master
Servicer or any of the directors, officers, employees or agents of the
Depositor, the Sellers, the NIM Insurer or the Master Servicer shall be under
any liability to the Trustee (except as provided in Section 8.05), the Trust
Fund or the Certificateholders for any action taken or for refraining from the
taking of any action in good faith pursuant to this Agreement, or for errors in
judgment; provided that this provision shall not protect the Depositor, the

Sellers, the Master Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or gross

desirable in respect of this Agreement and the rights and duties of the parties
hereto and interests of the Trustee and the Certificateholders hereunder. In

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

          The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except (i) upon determination that its duties hereunder
are no longer permissible under applicable law or (ii) upon appointment of a
successor servicer that is reasonably acceptable to the Trustee and the NIM
Insurer and the written confirmation from each Rating Agency (which
confirmation shall be furnished to the Depositor, the Trustee and the NIM
Insurer) that such resignation will not cause such Rating Agency to reduce the
then current rating of the Certificates. Any such determination pursuant to
clause (i) of the preceding sentence permitting the resignation of the Master
Servicer shall be evidenced by an Opinion of Counsel to such effect delivered
to the Trustee. No resignation of the Master Servicer shall become effective
until the Trustee shall have assumed the Master Servicer's responsibilities,
duties, liabilities (other than those liabilities arising prior to the
appointment of such successor) and obligations under this Agreement.

          Section 6.05  Errors and Omissions Insurance; Fidelity Bonds.

          The Master Servicer shall, for so long as it acts as servicer under
this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations
as servicer hereunder, and (b) a fidelity bond in respect of its officers,
employees and agents. Each such policy or policies and bond shall, together,
comply with the requirements from time to time of Fannie Mae and Freddie Mac
for persons performing servicing for mortgage loans purchased by Fannie Mae and
Freddie Mac. In the event that any such policy or bond ceases to be in effect,
the Master Servicer shall use its reasonable best efforts to obtain a
comparable replacement policy or bond from an insurer or issuer, meeting the
requirements set forth above as of the date of such replacement.

          The Master Servicer shall provide the Trustee and the NIM Insurer
(upon such party's reasonable request) with copies of any such insurance
policies and fidelity bond. The Master Servicer shall be deemed to have
complied with this provision if an Affiliate of the Master Servicer has such
errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Master Servicer.

          Section 7.01  Events of Default.
                        ------------------

          "Event of Default," wherever used herein, means any one of the
following events:

                  (1) any failure by the Master Servicer to deposit in the
          Certificate Account or the Distribution Account or remit to the
          Trustee any payment (excluding a payment required to be made under
          Section 4.01 hereof) required to be made under the terms of this
          Agreement, which failure shall continue unremedied for five calendar
          days and, with respect to a payment required to be made under Section
          4.01(b) or (c) hereof, for one Business Day, after the date on which
          written notice of such failure shall have been given to the Master
          Servicer by the Trustee, the NIM Insurer or the Depositor, or to

                                      115
<PAGE>

          the Trustee, the NIM Insurer and the Master Servicer by the Holders
          of Certificates evidencing not less than 25% of the Voting Rights; or

                  (2) any failure by the Master Servicer to observe or perform
          in any material respect any other of the covenants or agreements on
          the part of the Master Servicer contained in this Agreement or any
          representation or warranty shall prove to be untrue, which failure or
          breach shall continue unremedied for a period of 60 days after the
          date on which written notice of such failure shall have been given to
          the Master Servicer by the Trustee, the NIM Insurer or the Depositor,
          or to the Trustee by the Holders of Certificates evidencing not less
          than 25% of the Voting Rights; provided that the sixty-day cure
          period shall not apply to the initial delivery of the Mortgage File
          for Delay Delivery Mortgage Loans nor the failure to repurchase or
          substitute in lieu thereof; or

                  (3) a decree or order of a court or agency or supervisory
          authority having jurisdiction in the premises for the appointment of
          a receiver or liquidator in any insolvency, readjustment of debt,
          marshalling of assets and liabilities or similar proceedings, or for
          the winding-up or liquidation of its affairs, shall have been entered
          against the Master Servicer and such decree or order shall have
          remained in force undischarged or unstayed for a period of 60
          consecutive days; or

                  (4) the Master Servicer shall consent to the appointment of a
          receiver or liquidator in any insolvency, readjustment of debt,
          marshalling of assets and liabilities or similar proceedings of or
          relating to the Master Servicer or all or substantially all of the
          property of the Master Servicer; or

                  (5) the Master Servicer shall admit in writing its inability
          to pay its debts generally as they become due, file a petition to
          take advantage of, or commence a voluntary case under, any applicable
          insolvency or reorganization statute, make an assignment for the
          benefit of its creditors, or voluntarily suspend payment of its
          obligations; or

                  (6) the Master Servicer shall fail to reimburse in full the
          Trustee not later than 6:00 p.m. (New York time) on the Business Day
          following the related Distribution Date for any Advance made by the
          Trustee pursuant to Section 4.01(d) together with accrued and unpaid
          interest.

          If an Event of Default shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the
Trustee shall, but only at the direction of either the NIM Insurer or the
Holders of Certificates evidencing not less than 25% of the Voting Rights, by
notice in writing to the Master Servicer (with a copy to each Rating Agency),
terminate all of the rights and obligations of the Master Servicer under this
Agreement and in and to the Mortgage Loans and the proceeds thereof, other than
its rights as a Certificateholder hereunder. On or after the receipt by the
Master Servicer of such written notice, all authority and power of the Master
Servicer hereunder, whether with respect to the Mortgage Loans or otherwise,
shall pass to and be vested in the Trustee. The Trustee shall thereupon make
any Advance described in Section 4.01 hereof subject to Section 3.04 hereof.
The Trustee is hereby

                                      116
<PAGE>

authorized and empowered to execute and deliver, on behalf of the Master
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. Unless expressly provided in such written
notice, no such termination shall affect any obligation of the Master Servicer
to pay amounts owed pursuant to Article VIII. The Master Servicer agrees to
cooperate with the Trustee in effecting the termination of the Master
Servicer's responsibilities and rights hereunder, including, without
limitation, the transfer to the Trustee of all cash amounts which shall at the
time be credited to the Certificate Account, or thereafter be received with
respect to the Mortgage Loans. The Trustee shall promptly notify the Rating
Agencies of the occurrence of an Event of Default.

          Notwithstanding any termination of the activities of a Master
Servicer hereunder, such Master Servicer shall be entitled to receive, out of
any late collection of a Scheduled Payment on a Mortgage Loan that was due
prior to the notice terminating such Master Servicer's rights and obligations
as Master Servicer hereunder and received after such notice, that portion
thereof to which such Master Servicer would have been entitled pursuant to
Sections 3.08(a)(i) through (viii), and any other amounts payable to such
Master Servicer hereunder the entitlement to which arose prior to the
termination of its activities hereunder.

          Section 7.02  Trustee to Act; Appointment of Successor.
                        -----------------------------------------

          On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Master Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties
and liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof and applicable law including the obligation to make advances
pursuant to Section 4.01. As compensation therefor, the Trustee shall be
entitled to all fees, costs and expenses relating to the Mortgage Loans that
the Master Servicer would have been entitled to if the Master Servicer had
continued to act hereunder. Notwithstanding the foregoing, if the Trustee has
become the successor to the Master Servicer in accordance with Section 7.01
hereof, the Trustee may, if it shall be unwilling to so act, or shall, if it is
prohibited by applicable law from making Advances pursuant to Section 4.01
hereof or if it is otherwise unable to so act, (i) appoint any established
mortgage loan servicing institution reasonably acceptable to the NIM Insurer
(as evidenced by the prior written consent of the NIM Insurer), or (ii) if it
is unable for 60 days to appoint a successor servicer reasonably acceptable to
the NIM Insurer, petition a court of competent jurisdiction to appoint any
established mortgage loan servicing institution, the appointment of which does
not adversely affect the then current rating of the Certificates and the NIM
Insurer guaranteed notes (without giving effect to any policy or guaranty
provided by the NIM Insurer) by each Rating Agency as the successor to the
Master Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master Servicer hereunder. Any
successor Master Servicer shall be an institution that is a Fannie Mae and
Freddie Mac approved seller/servicer in good standing, that has been approved
by the Mortgage Insurer if required, that has a net worth of at least
$15,000,000 and that is willing to service the Mortgage Loans and executes and
delivers to the Depositor and the Trustee an agreement accepting such
delegation and assignment, that contains an assumption by such Person of the
rights, powers, duties,

                                      117
<PAGE>

responsibilities, obligations and liabilities of the Master Servicer (other
than liabilities and indemnities of the Master Servicer under Section 6.03
hereof incurred prior to termination of the Master Servicer under Section
7.01), with like effect as if originally named as a party to this Agreement;
and provided further that each Rating Agency acknowledges that its rating of
the Certificates in effect immediately prior to such assignment and delegation
will not be qualified or reduced as a result of such assignment and delegation.
No appointment of a successor to the Master Servicer hereunder shall be
effective until the Trustee shall have consented thereto, and written notice of
such proposed appointment shall have been provided by the Trustee to each
Certificateholder. The Trustee shall not resign as servicer until a successor
servicer has been appointed and has accepted such appointment. Pending
appointment of a successor to the Master Servicer hereunder, the Trustee,
unless the Trustee is prohibited by law from so acting, shall, subject to
Section 3.04 hereof, act in such capacity as herein above provided. In
connection with such appointment and assumption, the Trustee may make such
arrangements for the compensation of such successor out of payments on Mortgage
Loans as it and such successor shall agree; provided that no such compensation
shall be in excess of that permitted the Master Servicer hereunder. The Trustee
and such successor shall take such action, consistent with this Agreement, as
shall be necessary to effectuate any such succession. Neither the Trustee nor
any other successor servicer shall be deemed to be in default hereunder by
reason of any failure to make, or any delay in making, any distribution
hereunder or any portion thereof or any failure to perform, or any delay in
performing, any duties or responsibilities hereunder, in either case caused by
the failure of the Master Servicer to deliver or provide, or any delay in
delivering or providing, any cash, information, documents or records to it.

          Any successor to the Master Servicer as servicer shall give notice to
the NIM Insurer and the Mortgagors of such change of servicer and shall, during
the term of its service as servicer maintain in force the policy or policies
that the Master Servicer is required to maintain pursuant to Section 6.05.

          In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent
and warrant that it is a member of MERS in good standing and shall agree to
comply in all material respects with the rules and procedures of MERS in
connection with the servicing of the Mortgage Loans that are registered with
MERS, or (ii) the predecessor Master Servicer shall cooperate with the
successor Master Servicer in causing MERS to execute and deliver an assignment
of Mortgage in recordable form to transfer the Mortgage from MERS to the
Trustee and to execute and deliver such other notices, documents and other
instruments as may be necessary or desirable to effect a transfer of such
Mortgage Loan or servicing of such Mortgage Loan on the MERS(R) System to the
successor Master Servicer. The predecessor Master Servicer shall file or cause
to be filed any such assignment in the appropriate recording office. The
successor Master Servicer shall cause such assignment to be delivered to the
Co-Trustee promptly upon receipt of the original with evidence of recording
thereon or a copy certified by the public recording office in which such
assignment was recorded.

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

          (a)     Upon any termination of or appointment of a successor to the
Master Servicer, the Trustee shall give prompt written notice thereof to the
Certificateholders and to each Rating Agency.

          (b)     Within 60 days after the occurrence of any Event of Default,
the Trustee shall transmit by mail to all Certificateholders notice of each
such Event of Default hereunder known to the Trustee, unless such Event of
Default shall have been cured or waived.

          Section 8.01  Duties of Trustee.
                        ------------------

          The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default that may have occurred, shall undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred and remains uncured, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee (or the Co-Trustee, to the extent provided in this Agreement)
that are specifically required to be furnished pursuant to any provision of
this Agreement shall examine them to determine whether they conform to the
requirements of this Agreement, to the extent provided in this Agreement. If
any such instrument is found not to conform to the requirements of this
Agreement in a material manner, the Trustee shall take action as it deems
appropriate to have the instrument corrected.

          No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own grossly negligent action, its own gross
negligent failure to act or its own misconduct, its grossly negligent failure
to perform its obligations in compliance with this Agreement, or any liability
that would be imposed by reason of its willful misfeasance or bad faith;
provided that:

                  (1) prior to the occurrence of an Event of Default, and after
          the curing of all such Events of Default that may have occurred, the
          duties and obligations of the Trustee shall be determined solely by
          the express provisions of this Agreement, the Trustee shall not be
          liable, individually or as Trustee, except for the performance of
          such duties and obligations as are specifically set forth in this
          Agreement, no implied covenants or obligations shall be read into
          this Agreement against the Trustee and the Trustee may conclusively
          rely, as to the truth of the statements and the correctness of the
          opinions expressed therein, upon any certificates or opinions
          furnished to the Trustee and conforming to the requirements of this
          Agreement that it reasonably believed in good faith to be genuine and
          to have been duly executed by the proper authorities respecting any
          matters arising hereunder;

                                      119
<PAGE>

                  (2) the Trustee shall not be liable, individually or as
          Trustee, for an error of judgment made in good faith by a Responsible
          Officer or Responsible Officers of the Trustee, unless the Trustee
          was grossly negligent or acted in bad faith or with willful
          misfeasance;

                  (3) the Trustee shall not be liable, individually or as
          Trustee, with respect to any action taken, suffered or omitted to be
          taken by it in good faith in accordance with the direction of the
          Holders of each Class of Certificates evidencing not less than 25% of
          the Voting Rights of such Class relating to the time, method and
          place of conducting any proceeding for any remedy available to the
          Trustee, or exercising any trust or power conferred upon the Trustee
          under this Agreement; and

                  (4) without in any way limiting the provisions of this
          Section 8.01 or Section 8.02 hereof, the Trustee shall be entitled to
          rely conclusively on the information delivered to it by the Master
          Servicer in a Trustee Advance Notice in determining whether or not it
          is required to make an Advance under Section 4.01(d), shall have no
          responsibility to ascertain or confirm any information contained in
          any Trustee Advance Notice, and shall have no obligation to make any
          Advance under Section 4.01(d) in the absence of a Trustee Advance
          Notice or actual knowledge by a Responsible Officer that (A) a
          required Advance was not made and (B) such required Advance was not a
          Nonrecoverable Advance.

          Section 8.02  Certain Matters Affecting the Trustee.
                        --------------------------------------

          (a)     Except as otherwise provided in Section 8.01:

                  (1) the Trustee may request and rely upon and shall be
          protected in acting or refraining from acting upon any resolution,
          Officer's Certificate, certificate of auditors or any other
          certificate, statement, instrument, opinion, report, notice, request,
          consent, order, appraisal, bond or other paper or document believed
          by it to be genuine and to have been signed or presented by the
          proper party or parties;

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

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

                  (4) prior to the occurrence of an Event of Default hereunder
          and after the curing of all Events of Default that may have occurred,
          the Trustee shall not be bound to make any investigation into the
          facts or matters stated in any resolution, certificate, statement,
          instrument, opinion, report, notice, request, consent, order,
          approval, bond or other paper or document, unless requested in
          writing so to do by the NIM Insurer or the Holders of each Class of
          Certificates evidencing not less than 25% of the Voting Rights of
          such Class; provided, however, that if the payment within a
          reasonable time to the

                                      120
<PAGE>

          Trustee of the costs, expenses or liabilities likely to be incurred
          by it in the making of such investigation is, in the opinion of the
          Trustee not reasonably assured to the Trustee by such
          Certificateholders, the Trustee may require reasonable indemnity
          against such expense, or liability from such Certificateholders as a
          condition to taking any such action;

                  (5) the Trustee may execute any of the trusts or powers
          hereunder or perform any duties hereunder either directly or by or
          through agents, accountants or attorneys;

                  (6) the Trustee shall not be required to expend its own funds
          or otherwise incur any financial liability in the performance of any
          of its duties hereunder if it shall have reasonable grounds for
          believing that repayment of such funds or adequate indemnity against
          such liability is not assured to it;

                  (7) the Trustee shall not be liable, individually or as
          Trustee, for any loss on any investment of funds pursuant to this
          Agreement (other than as issuer of the investment security);

                  (8) the Trustee shall not be deemed to have knowledge of an
          Event of Default until a Responsible Officer of the Trustee shall
          have received written notice thereof; and

                  (9) the Trustee shall be under no obligation to exercise any
          of the trusts or powers vested in it by this Agreement or to make any
          investigation of matters arising hereunder or to institute, conduct
          or defend any litigation hereunder or in relation hereto at the
          request, order or direction of the NIM Insurer or any of the
          Certificateholders, pursuant to the provisions of this Agreement,
          unless the NIM Insurer or such Certificateholders, as applicable,
          shall have offered to the Trustee reasonable security or indemnity
          against the costs, expenses and liabilities that may be incurred
          therein or thereby.

          (b)     All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee
without the possession of any of the Certificates, or the production thereof at
the trial or other proceeding relating thereto, and any such suit, action or
proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

          Section 8.03  Trustee Not Liable for Mortgage Loans.
                        --------------------------------------

          The recitals contained herein shall be taken as the statements of the
Depositor or the Master Servicer, as the case may be, and the Trustee assumes
no responsibility for their correctness. The Trustee makes no representations
as to the validity or sufficiency of this Agreement or of any Mortgage Loan or
related document or of MERS or the MERS(R) System other than with respect to
the Trustee's execution and authentication of the Certificates. The Trustee
shall not be accountable for the use or application by the Depositor or the
Master Servicer of any funds paid to the Depositor or the Master Servicer in
respect of the Mortgage Loans or deposited in or withdrawn from the Certificate
Account by the Depositor or the Master Servicer.

          Section 8.04  Trustee May Own Certificates.
                        -----------------------------

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

          Section 8.05  Master Servicer to Pay Trustee's Fees and Expenses.
                        ---------------------------------------------------

          The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement (including, without
limitation: (A) the reasonable compensation and the expenses and disbursements
of its counsel, but only for representation of the Trustee acting in its
capacity as Trustee hereunder and (B) to the extent that the Trustee must
engage persons not regularly in its employ to perform acts or services on
behalf of the Trust Fund, which acts or services are not in the ordinary course
of the duties of a trustee, paying agent or certificate registrar, in the
absence of a breach or default by any party hereto, the reasonable
compensation, expenses and disbursements of such persons, except any such
expense, disbursement or advance as may arise from its negligence, bad faith or
willful misconduct). The Trustee and any director, officer, employee or agent
of the Trustee shall be indemnified by the Master Servicer and held harmless
against any loss, liability or expense (i) incurred in connection with any
legal action relating to this Agreement or the Certificates, or in connection
with the performance of any of the Trustee's duties hereunder, other than any
loss, liability or expense incurred by reason of willful misfeasance, bad faith
or negligence in the performance of any of the Trustee's duties hereunder or by
reason of reckless disregard of the Trustee's obligations and duties hereunder
or (ii) resulting from any error in any tax or information return prepared by
the Master Servicer. Such indemnity shall survive the termination of this
Agreement or the resignation or removal of the Trustee hereunder.

          Section 8.06  Eligibility Requirements for Trustee.
                        -------------------------------------

          The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and with a
credit rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation or
national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Sellers and the Master Servicer and
their respective affiliates; provided that such corporation cannot be an

                                      122
<PAGE>

affiliate of the Master Servicer other than the Trustee in its role as
successor to the Master Servicer.

          Section 8.07  Resignation and Removal of Trustee.
                        -----------------------------------

          The Trustee may at any time resign and be discharged from the trusts
hereby created by (1) giving written notice of resignation to the Depositor and
the Master Servicer and by mailing notice of resignation by first class mail,
postage prepaid, to the Certificateholders at their addresses appearing on the
Certificate Register and each Rating Agency, not less than 60 days before the
date specified in such notice when, subject to Section 8.08, such resignation
is to take effect, and (2) acceptance of appointment by a successor trustee in
accordance with Section 8.08 and meeting the qualifications set forth in
Section 8.06. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice or
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

          If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 hereof and shall fail to resign
after written request thereto by the NIM Insurer or the Depositor, (ii) the
Trustee shall become incapable of acting, or shall be adjudged as bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, or (iii)(A) a tax is imposed with respect to the Trust Fund by any
state in which the Trustee or the Trust Fund is located, (B) the imposition of
such tax would be avoided by the appointment of a different trustee and (C) the
Trustee fails to indemnify the Trust Fund against such tax, then the Depositor,
the NIM Insurer or the Master Servicer may remove the Trustee and appoint a
successor trustee, reasonably acceptable to the NIM Insurer, by written
instrument, in triplicate, one copy of which instrument shall be delivered to
the Trustee, one copy of which shall be delivered to the Master Servicer and
one copy of which shall be delivered to the successor trustee.

          The Holders evidencing at least 51% of the Voting Rights of each
Class of Certificates may at any time remove the Trustee and appoint a
successor trustee by written instrument or instruments, in triplicate, signed
by such Holders or their attorneys-in-fact duly authorized, one complete set of
which instruments shall be delivered by the successor Trustee to the Master
Servicer one complete set to the Trustee so removed and one complete set to the
successor so appointed. Notice of any removal of the Trustee shall be given to
each Rating Agency by the successor Trustee.

          Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08 hereof.

          Section 8.08  Successor Trustee.
                        ------------------

          Any successor trustee appointed as provided in Section 8.07 hereof
shall execute, acknowledge and deliver to the Depositor, its predecessor
trustee and the Master Servicer an instrument accepting such appointment
hereunder and thereupon the resignation or removal of

                                      123
<PAGE>

the predecessor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor hereunder, with
the like effect as if originally named as trustee herein. In addition, if the
Corridor Contract is still outstanding, the Person appointed as successor
trustee shall execute, acknowledge and deliver to the predecessor trustee, CHL
and the Master Servicer an instrument accepting the appointment as successor
Corridor Contract Administrator under the Corridor Contract Administration
Agreement.

          No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer and its appointment shall not adversely affect
the then current ratings of the Certificates.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to the NIM Insurer and all Holders of Certificates. If the
Depositor fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

          Section 8.09  Merger or Consolidation of Trustee.
                        -----------------------------------

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

          Section 8.10  Appointment of Co-Trustee or Separate Trustee.
                        ----------------------------------------------

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

                                      124
<PAGE>

8.06 and no notice to Certificateholders of the appointment of any co-trustee
or separate trustee shall be required under Section 8.08.

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

                  (1) All rights, powers, duties and obligations conferred or
          imposed upon the Trustee, except for the obligation of the Trustee
          under this Agreement to advance funds on behalf of the Master
          Servicer, shall be conferred or imposed upon and exercised or
          performed by the Trustee and such separate trustee or co-trustee
          jointly (it being understood that such separate trustee or co-trustee
          is not authorized to act separately without the Trustee joining in
          such act), except to the extent that under any law of any
          jurisdiction in which any particular act or acts are to be performed
          (whether as Trustee hereunder or as successor to the Master Servicer
          hereunder), the Trustee shall be incompetent or unqualified to
          perform such act or acts, in which event such rights, powers, duties
          and obligations (including the holding of title to the Trust Fund or
          any portion thereof in any such jurisdiction) shall be exercised and
          performed singly by such separate trustee or co-trustee, but solely
          at the direction of the Trustee;

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

                  (3) The Trustee may at any time accept the resignation of or
          remove any separate trustee or co-trustee.

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

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

          Section 8.11  Tax Matters.
                        ------------

          It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC created
pursuant to the Preliminary Statement qualifies as, a "real estate mortgage
investment conduit" as defined in and in accordance with the

                                      125
<PAGE>

REMIC Provisions. In furtherance of such intention, the Trustee covenants and
agrees that it shall act as agent (and the Trustee is hereby appointed to act
as agent) on behalf of the Trust Fund and that in such capacity it shall: (a)
prepare and file, or cause to be prepared and filed, in a timely manner, a U.S.
Real Estate Mortgage Investment Conduit Income Tax Returns (Form 1066 or any
successor form adopted by the Internal Revenue Service) and prepare and file or
cause to be prepared and filed with the Internal Revenue Service and applicable
state or local tax authorities income tax or information returns for each
taxable year with respect to each REMIC created hereunder containing such
information and at the times and in the manner as may be required by the Code
or state or local tax laws, regulations, or rules, and furnish or cause to be
furnished to Certificateholders the schedules, statements or information at
such times and in such manner as may be required thereby; (b) within thirty
days of the Closing Date, furnish or cause to be furnished to the Internal
Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the
name, title, address, and telephone number of the person that the Holders of
the Certificates may contact for tax information relating thereto, together
with such additional information as may be required by such Form, and update
such information at the time or times in the manner required by the Code for
the Trust Fund; (c) make or cause to be made elections, on behalf of each REMIC
created hereunder to be treated as a REMIC on the federal tax return of each
such REMIC for its first taxable year (and, if necessary, under applicable
state law); (d) prepare and forward, or cause to be prepared and forwarded, to
the Certificateholders and to the Internal Revenue Service and, if necessary,
state tax authorities, all information returns and reports as and when required
to be provided to them in accordance with the REMIC Provisions, including
without limitation, the calculation of any original issue discount using the
Prepayment Assumption; (e) provide information necessary for the computation of
tax imposed on the transfer of a Class A-R Certificate to a Person that is not
a Permitted Transferee, or an agent (including a broker, nominee or other
middleman) of a Non-Permitted Transferee, or a pass-through entity in which a
Non-Permitted Transferee is the record holder of an interest (the reasonable
cost of computing and furnishing such information may be charged to the Person
liable for such tax); (f) to the extent that they are under its control conduct
the affairs of the Trust Fund at all times that any Certificates are
outstanding so as to maintain the status of each REMIC created hereunder as a
REMIC under the REMIC Provisions; (g) not knowingly or intentionally take any
action or omit to take any action that would cause the termination of the REMIC
status of any REMIC created hereunder; (h) pay, from the sources specified in
the penultimate paragraph of this Section 8.11, the amount of any federal,
state and local taxes, including prohibited transaction taxes as described
below, imposed on any REMIC created hereunder prior to the termination of the
Trust Fund when and as the same shall be due and payable (but such obligation
shall not prevent the Trustee or any other appropriate Person from contesting
any such tax in appropriate proceedings and shall not prevent the Trustee from
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings); (i) sign or cause to be signed federal, state or local
income tax or information returns; (j) maintain records relating to each REMIC
created hereunder, including but not limited to the income, expenses, assets
and liabilities of each such REMIC, and the fair market value and adjusted
basis of the Trust Fund property determined at such intervals as may be
required by the Code, as may be necessary to prepare the foregoing returns,
schedules, statements or information; and (k) as and when necessary and
appropriate, represent the Trust Fund in any administrative or judicial
proceedings relating to an examination or audit by any governmental taxing
authority, request an administrative adjustment as to any taxable year of any
REMIC created hereunder, enter into

                                      126
<PAGE>

settlement agreements with any governmental taxing agency, extend any statute
of limitations relating to any tax item of the Trust Fund, and otherwise act on
behalf of any REMIC created hereunder in relation to any tax matter involving
any such REMIC.

          In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within 10 days after the Closing Date all information or data that the Trustee
requests in writing and determines to be relevant for tax purposes to the
valuations and offering prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flows of
the Certificates and the Mortgage Loans (and, to the extent not part of the
aforementioned, the information referred to in paragraphs (1), (2), (3) and (4)
of Section 4.05(d)). Thereafter, the Depositor shall provide to the Trustee
promptly upon written request therefor, any such additional information or data
that the Trustee may, from time to time, request in order to enable the Trustee
to perform its duties as set forth herein. The Depositor hereby indemnifies the
Trustee for any losses, liabilities, damages, claims or expenses of the Trustee
arising from any errors or miscalculations of the Trustee that result from any
failure of the Depositor to provide, or to cause to be provided, accurate
information or data to the Trustee on a timely basis.

          In the event that any tax is imposed on "prohibited transactions" of
the Trust Fund as defined in section 860F(a)(2) of the Code, on the "net income
from foreclosure property" of the Trust Fund as defined in section 860G(c) of
the Code, on any contribution to the Trust Fund after the startup day pursuant
to section 860G(d) of the Code, or any other tax is imposed, including, without
limitation, any federal, state or local tax or minimum tax imposed upon the
Trust Fund pursuant to sections 23153 and 24872 of the California Revenue and
Taxation Code if not paid as otherwise provided for herein, such tax shall be
paid by (i) the Trustee, if any such other tax arises out of or results from a
breach by the Trustee of any of its obligations under this Agreement, (ii) (x)
the Master Servicer, in the case of any such minimum tax, and (y) any party
hereto (other than the Trustee) to the extent any such other tax arises out of
or results from a breach by such other party of any of its obligations under
this Agreement or (iii) in all other cases, or in the event that any liable
party here fails to honor its obligations under the preceding clauses (i) or
(ii), any such tax will be paid first with amounts otherwise to be distributed
to the Class A-R Certificateholders, and second with amounts otherwise to be
distributed to all other Certificateholders in the same manner as if such tax
were a Realized Loss. Notwithstanding anything to the contrary contained
herein, to the extent that such tax is payable by the Class A-R Certificates,
the Trustee is hereby authorized to retain on any Distribution Date, from the
Holders of the Class A-R Certificates (and, if necessary, second, from the
Holders of the all other Certificates in the priority specified in the
preceding sentence), funds otherwise distributable to such Holders in an amount
sufficient to pay such tax. The Trustee agrees to promptly notify in writing
the party liable for any such tax of the amount thereof and the due date for
the payment thereof.

          The Trustee shall treat the Carryover Reserve Fund as an outside
reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is
owned by the Holders of the Class C Certificates, and that is not an asset of
any REMIC created hereunder. The Trustee shall treat the rights of the Holders
of each Class of Certificates (other than the Class P and Class A-R
Certificates) to receive payments from the Carryover Reserve Fund as rights in
an interest rate corridor contract written by: (i) the Corridor Contract
Counterparty in respect of any Net Rate

                                      127
<PAGE>

Carryover funded by the Corridor Contract and in respect of any residual
payments from the Corridor Contract received by the Class C Certificates, and
(ii) the Holders of the Class C Certificates in respect of any monies
distributed pursuant to Section 4.04(d)(18) and (19) and Section 4.08(c)
herein, in favor of the other Certificateholders. Thus, each Certificate (other
than the Class P and Class A-R Certificates) shall be treated as representing
ownership of not only an Master REMIC regular interest, but also ownership of
an interest in an interest rate corridor contract. For purposes of determining

          (a)     The Co-Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Co-Trustee that are specifically required to be furnished pursuant to
any provision of this Agreement shall examine them to determine whether they
conform to the requirements of this Agreement, to the extent required by this
Agreement. If any such instrument is found not to conform to the requirements
of this Agreement in a material manner, the Co-Trustee shall take action as it
deems appropriate to have the instrument corrected. In addition, the Co-Trustee

appropriate or required of the Co-Trustee under the Mortgage Insurance Policy,
other than the payment of the Mortgage Insurance Premium and obtaining the
approval of the Mortgage Insurer with respect to the appointment of a successor
servicer.

          (b)     No provision of this Agreement shall be construed to relieve
the Co-Trustee from liability for its own grossly negligent action, its own
gross negligent failure to act or its own misconduct, its grossly negligent
failure to perform its obligations in compliance with this Agreement, or any
liability that would be imposed by reason of its willful misfeasance or bad
faith; provided that:

                  (1) the duties and obligations of the Co-Trustee shall be

          the exception of Section 8.10, the Co-Trustee shall not be liable,
          individually or as Co-Trustee, except for the performance of such
          duties and obligations as are specifically set forth in this
          Agreement, no implied covenants or obligations shall be read into
          this Agreement against the Co-Trustee and the Co-Trustee may
          conclusively rely, as to the truth of the statements and the
          correctness of the opinions expressed therein, upon any certificates
          or opinions furnished to the Co-Trustee and conforming to the
          requirements of this Agreement that it reasonably believed in good
          faith to be genuine and to have been duly executed by the proper
          authorities respecting any matters arising hereunder; and

                  (2) the Co-Trustee shall not be liable, individually or as
          Co-Trustee, for an error of judgment made in good faith by a
          Responsible Officer or Responsible Officers of the Trustee, unless
          the Co-Trustee was grossly negligent or acted in bad faith or with
          willful misfeasance.

          (c)     Except as otherwise provided in paragraph (b) above:

                  (1) the Co-Trustee may request and rely upon and shall be
          protected in acting or refraining from acting upon any resolution,
          Officer's Certificate, certificate of auditors or any other
          certificate, statement, instrument, opinion, report, notice, request,
          consent, order, appraisal, bond or other paper or document believed
          by it to be genuine and to have been signed or presented by the
          proper party or parties;

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

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

                  (4) the Co-Trustee shall not be bound to make any
          investigation into the facts or matters stated in any resolution,
          certificate, statement, instrument, opinion, report, notice, request,
          consent, order, approval, bond or other paper or document;

                  (5) the Co-Trustee may execute any of the trusts or powers
          hereunder or perform any duties hereunder either directly or by or
          through agents, accountants or attorneys; and

                  (6) the Co-Trustee shall not be required to expend its own
          funds or otherwise incur any financial liability in the performance
          of any of its duties hereunder if it shall have reasonable grounds
          for believing that repayment of such funds or adequate indemnity
          against such liability is not assured to it.

          (d)     The recitals contained herein shall be taken as the
statements of the Depositor or the Master Servicer, as the case may be, and the
Co-Trustee assumes no responsibility for their correctness. The Co-Trustee
makes no representations as to the validity or sufficiency of this Agreement or
of any Mortgage Loan or related document or of MERS or the MERS(R) System. The
Co-Trustee shall not be accountable for the use or application by the Depositor
or the Master Servicer of any funds paid to the Depositor or the Master
Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the
Certificate Account by the Depositor or the Master Servicer.

          (e)     The Co-Trustee in its individual or any other capacity may
become the owner or pledgee of Certificates with the same rights as it would
have if it were not the Co-Trustee.

          (f)     The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) for all services

                                      129
<PAGE>

rendered by it in the execution of the trusts hereby created and in the
exercise and performance of any of the powers and duties hereunder of the
Co-Trustee and (ii) to pay or reimburse the Co-Trustee, upon its request, for
all reasonable expenses, disbursements and advances incurred or made by the
Co-Trustee on behalf of the Trust Fund in accordance with any of the provisions
of this Agreement (including, without limitation: (A) the reasonable
compensation and the expenses and disbursements of its counsel, but only for
representation of the Co-Trustee acting in its capacity as Co-Trustee hereunder
and (B) to the extent that the Co-Trustee must engage persons not regularly in
its employ to perform acts or services on behalf of the Trust Fund, which acts
or services are not in the ordinary course of the duties of a trustee, paying
agent or certificate registrar, in the absence of a breach or default by any
party hereto, the reasonable compensation, expenses and disbursements of such
persons, except any such expense, disbursement or advance as may arise from its
negligence, bad faith or willful misconduct). The Co-Trustee and any director,
officer, employee or agent of the Co-Trustee shall be indemnified by the Master
Servicer and held harmless against any loss, liability or expense (i) incurred
in connection with any legal action relating to this Agreement or the
Certificates, or in connection with the performance of any of the Co-Trustee's
duties hereunder, other than any loss, liability or expense incurred by reason
of willful misfeasance, bad faith or negligence in the performance of any of
the Co-Trustee's duties hereunder or by reason of reckless disregard of the
Co-Trustee's obligations and duties hereunder and (ii) resulting from any error
in any tax or information return prepared by the Master Servicer. Such
indemnity shall survive the termination of this Agreement or the resignation or
removal of the Co-Trustee hereunder.

          (g)     The Co-Trustee hereunder shall, at all times, be a
corporation or association organized and doing business under the laws of a
state or the United States of America, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000, subject to supervision or examination by federal or state
authority and with a credit rating that would not cause any of the Rating
Agencies to reduce their respective ratings of any Class of Certificates below
the ratings issued on the Closing Date (or having provided such security from
time to time as is sufficient to avoid such reduction). If such corporation or
association publishes reports of condition at least annually, pursuant to law
or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section 8.12 the combined capital and surplus of
such corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately in
the manner and with the effect specified in paragraph (h) below. The
corporation or national banking association serving as Co-Trustee may have
normal banking and trust relationships with the Depositor, the Sellers and the
Master Servicer and their respective affiliates; provided that such corporation
cannot be an affiliate of the Master Servicer other than the Trustee in its
role as successor to the Master Servicer.

          (h)     The Co-Trustee may at any time resign and be discharged from
the trusts hereby created by giving 30 days prior written notice of resignation
to the Trustee, the Depositor and the Master Servicer. Upon such resignation
the Trustee (x) may appoint a successor Co-Trustee meeting the requirements in
paragraph (g) above and acceptable to the Master Servicer and the NIM Insurer
(in their sole discretion), so long as such Co-Trustee executes and delivers to
the other parties hereto an instrument agreeing to be bound by the provisions
of this

                                      130
<PAGE>

Agreement or (y) may if permitted by the Master Servicer (in its sole
discretion) assume the rights and duties of the resigning Co-Trustee so long as
the Trustee executes and delivers an instrument to that effect.

          Section 8.13  Access to Records of the Trustee.
                        ---------------------------------

          The Trustee and any Co-Trustee shall afford the Sellers, the
Depositor, the Master Servicer, the NIM Insurer and each Certificate Owner upon
reasonable notice during normal business hours access to all records maintained
by the Trustee or Co-Trustee in respect of its duties under this Agreement and
access to officers of the Trustee responsible for performing its duties. Upon
request, the Trustee or Co-Trustee shall furnish the Depositor, the Master
Servicer, the NIM Insurer and any requesting Certificate Owner with its most
recent financial statements. The Trustee shall cooperate fully with the
Sellers, the Master Servicer, the Depositor, the NIM Insurer and the
Certificate Owner for review and copying any books, documents, or records
requested with respect to the Trustee's and Co-Trustee's respective duties
under this Agreement. The Sellers, the Depositor, the Master Servicer, and the
Certificate Owner shall not have any responsibility or liability for any action
for failure to act by the Trustee or Co-Trustee and are not obligated to
supervise the performance of the Trustee under this Agreement or otherwise.

          Section 8.14  Suits for Enforcement.
                        ----------------------

          If an Event of Default or other material default by the Master
Servicer or the Depositor under this Agreement occurs and is continuing, at the
direction of the Certificateholders holding not less than 51% of the Voting
Rights or the NIM Insurer, the Trustee shall proceed to protect and enforce its
rights and the rights of the Certificateholders or the NIM Insurer under this
Agreement by a suit, action, or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this
Agreement or for the enforcement of any other legal, equitable, or other
remedy, as the Trustee, being advised by counsel, and subject to the foregoing,
shall deem most effectual to protect and enforce any of the rights of the
Trustee, the NIM Insurer and the Certificateholders.

                                  TERMINATION

          Section 9.01  Termination upon Liquidation or Repurchase of all
                        -------------------------------------------------
                        Mortgage Loans.
                        ---------------

          Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Sellers, the Trustee and the Co-Trustee created hereby shall terminate upon the
earlier of (a) the purchase by the Master Servicer or NIM Insurer (the party
exercising such purchase option, the "Terminator") of all of the Mortgage Loans
(and REO Properties) remaining in the Trust Fund at the price equal to the sum
of (i) 100% of the Stated Principal Balance of each Mortgage Loan in the Trust
Fund (other than in respect of an REO Property), (ii) accrued interest thereon
at the applicable Mortgage Rate (or, if such repurchase is effected by the
Master Servicer, at the applicable Net Mortgage Rate), (iii) the appraised
value of any REO Property in the Trust Fund (up to the Stated Principal Balance
of the

                                      131
<PAGE>

related Mortgage Loan), such appraisal to be conducted by an appraiser mutually
agreed upon by the Terminator and the Trustee, and (iv) if the Terminator is
the NIM Insurer, any unreimbursed Servicing Advances, and the principal portion
of any unreimbursed Advances, made on the Mortgage Loans prior to the exercise
of such repurchase and (b) the later of (i) the maturity or other liquidation
(or any Advance with respect thereto) of the last Mortgage Loan remaining in
the Trust Fund and the disposition of all REO Property and (ii) the
distribution to related Certificateholders of all amounts required to be
distributed to them pursuant to this Agreement, as applicable. In no event
shall the trusts created hereby continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants
of Joseph P. Kennedy, the late Ambassador of the United States to the Court of
St. James's, living on the date hereof and (ii) the Latest Possible Maturity
Date.

          The right to purchase all Mortgage Loans and REO Properties by the
Terminator pursuant to clause (a) of the immediately preceding paragraph shall
be conditioned upon (1) the Stated Principal Balance of the Mortgage Loans, at
the time of any such repurchase, aggregating ten percent (10%) or less of the
sum of (x) the aggregate Cut-off Date Principal Balance of the Initial Mortgage
Loans and (y) the Pre-Funded Amount, and (2) unless the NIM Insurer otherwise
consents, the purchase price for such Mortgage Loans and REO Properties shall
result in a final distribution on any NIM Insurer guaranteed notes that is
sufficient (x) to pay such notes in full and (y) to pay any amounts due and
payable to the NIM Insurer pursuant to the indenture related to such notes. The
NIM Insurer's right to purchase all Mortgage Loans and REO Properties shall be
further conditioned upon the written consent of the Master Servicer.

          Section 9.02  Final Distribution on the Certificates.
                        ---------------------------------------

          If on any Determination Date, (i) the Master Servicer determines that
there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Certificate Account, the Master Servicer
shall direct the Trustee to send a final distribution notice promptly to each
related Certificateholder or (ii) the Trustee determines that a Class of
Certificates shall be retired after a final distribution on such Class, the
Trustee shall notify the related Certificateholders within five (5) Business
Days after such Determination Date that the final distribution in retirement of
such Class of Certificates is scheduled to be made on the immediately following
Distribution Date. Any final distribution made pursuant to the immediately
preceding sentence will be made only upon presentation and surrender of the
related Certificates at the Corporate Trust Office of the Trustee. If the
Terminator elects to terminate pursuant to clause (a) of Section 9.01, at least
20 days prior to the date notice is to be mailed to the affected
Certificateholders, such electing party shall notify the Depositor and the
Trustee of the date such electing party intends to terminate and of the
applicable repurchase price of the related Mortgage Loans and REO Properties.

          Notice of any termination, specifying the Distribution Date on which
related Certificateholders may surrender their Certificates for payment of the
final distribution and cancellation, shall be given promptly by the Trustee by
letter to related Certificateholders mailed not earlier than the 10th day and
no later than the 15th day of the month immediately preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date
upon which final distribution on related Certificates will be made upon
presentation and surrender of such Certificates at the office therein
designated, (b) the amount of such final distribution, (c) the

                                      132
<PAGE>

location of the office or agency at which such presentation and surrender must
be made and (d) that the Record Date otherwise applicable to such Distribution
Date is not applicable, distributions being made only upon presentation and
surrender of such Certificates at the office therein specified. The Terminator
will give such notice to each Rating Agency at the time such notice is given to
the affected Certificateholders.

          In the event such notice is given, the Master Servicer shall cause
all funds in the Certificate Account to be remitted to the Trustee for deposit
in the Distribution Account on the Business Day prior to the applicable
Distribution Date in an amount equal to the final distribution in respect of
the Certificates. Upon such final deposit and the receipt by the Trustee of a
Request for File Release therefor, the Co-Trustee shall promptly release to the
Master Servicer the Mortgage Files for the Mortgage Loans.

          Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to Certificateholders of each affected Class the
amounts allocable to such Certificates held in the Distribution Account (and,
if applicable, the Carryover Reserve Fund) in the order and priority set forth
in Section 4.04 hereof on the final Distribution Date and in proportion to
their respective Percentage Interests. Notwithstanding the reduction of the
Certificate Principal Balance of any Class of Certificates to zero, such Class
will be outstanding hereunder (solely for the purpose of receiving
distributions (if any) to which it may be entitled pursuant to the terms of
this Agreement and not for any other purpose) until the termination of the
respective obligations and responsibilities of the Depositor, each Seller, the
Master Servicer and the Trustee hereunder in accordance with Article IX.

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

          Section 9.03  Additional Termination Requirements.
                        ------------------------------------

          (a)     In the event the Terminator exercises its purchase option,
the Trust Fund shall be terminated in accordance with the following additional
requirements, unless the Trustee has been supplied with an Opinion of Counsel,
at the expense of the Terminator, to the effect that the failure of the Trust
Fund to comply with the requirements of this Section 9.03 will not (i) result
in the imposition of taxes on "prohibited transactions" of a REMIC, or (ii)
cause any REMIC created hereunder to fail to qualify as a REMIC at any time
that any Certificates are outstanding:

                  (1) The Master Servicer shall establish a 90-day liquidation
period and notify the Trustee thereof, which shall in turn specify the first
day of such period in a statement attached to the Trust Fund's final Tax Return
pursuant to Treasury Regulation Section 1.860F-1. The Master Servicer shall
prepare a plan of complete liquidation and shall otherwise satisfy all the
requirements of a qualified liquidation under Section 860F of the Code and any
regulations thereunder, as evidenced by an Opinion of Counsel delivered to the
Trustee and the Depositor obtained at the expense of the Terminator;

                  (2) During such 90-day liquidation period, and at or prior to
the time of making the final payment on the Certificates, the Master Servicer
as agent of the Trustee shall sell all of the assets of the Trust Fund to the
Terminator for cash; and

                  (3) At the time of the making of the final payment on the
Certificates, the Trustee shall distribute or credit, or cause to be
distributed or credited, to the Class A-R Certificateholders all cash on hand
(other than cash retained to meet claims) related to such Class of
Certificates, and the Trust Fund shall terminate at that time.

          (b)     By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to specify the 90-day liquidation period
for the Trust Fund, which authorization shall be binding upon all successor
Certificateholders. The Trustee shall attach a statement to the final federal
income tax return for each of any REMIC created hereunder stating that pursuant
to Treasury Regulation Section 1.860F-1, the first day of the 90-day
liquidation period for each the REMIC was the date on which the Trustee sold
the assets of the Trust Fund to the Terminator.

          (c)     The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1), and together with the Holders of the Class
A-R Certificates agree to take such other action in connection therewith as may
be reasonably requested by the Terminator.

                            MISCELLANEOUS PROVISIONS

          Section 10.01 Amendment.
                        ----------

          This Agreement may be amended from time to time by the Depositor, the
Master Servicer, the Sellers, the Co-Trustee and the Trustee with the consent
of the NIM Insurer, without the consent of any of the Certificateholders (i) to
cure any ambiguity, (ii) to correct or supplement any provisions herein, (iii)
to conform this Agreement to the Prospectus Supplement or the Prospectus, (iv)
to modify, alter, amend, add to or rescind any of the terms or provisions
contained in this Agreement to comply with any rules or regulations promulgated
by the Securities and Exchange Commission from time to time, or (v) to make
such other provisions with respect to matters or questions arising under this
Agreement, as shall not be inconsistent with any other provisions herein if
such action shall not, as evidenced by an Opinion of Counsel, adversely affect
in any material respect the interests of any Certificateholder; provided that
any such amendment shall be deemed not to adversely affect in any material
respect the interests of the Certificateholders and no such Opinion of Counsel
shall be required if the Person requesting such amendment obtains a letter from
each Rating Agency stating that such amendment would not result in the
downgrading or withdrawal of the respective ratings then assigned to the
Certificates, it being understood and agreed that any such letter in and of
itself will not represent a determination as to the materiality of any such
amendment and will represent a determination only as to the credit issues
affecting any such rating. Any amendment described above made solely to conform
this Agreement to the Prospectus or the Prospectus Supplement shall be deemed
not to adversely affect in any material respect the interests of the
Certificateholders. Notwithstanding the foregoing, no amendment that
significantly changes the permitted activities of the trust created by this
Agreement may be made without the consent of Certificateholders representing
not less than 51% of the Voting Rights of each Class of Certificates affected
by such amendment. Each party to this Agreement hereby agrees that it will
cooperate with each other party in amending this Agreement pursuant to clause
(iv) above.

          The Trustee, the Co-Trustee, the Depositor, the Master Servicer and
the Sellers with the consent of the NIM Insurer may also at any time and from
time to time amend this Agreement, without the consent of the
Certificateholders, to modify, eliminate or add to any of its provisions to
such extent as shall be necessary or appropriate to maintain the qualification
of the Trust Fund as a REMIC under the Code or to avoid or minimize the risk of
the imposition of any tax on the Trust Fund pursuant to the Code that would be
a claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee has been provided an Opinion of
Counsel, which opinion shall be an expense of the party requesting such opinion
but in any case shall not be an expense of the Trustee, to the effect that such
action is necessary or appropriate to maintain such qualification or to avoid
or minimize the risk of the imposition of such a tax.

          This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Sellers, the Co-Trustee and the Trustee
with the consent of the NIM Insurer and the Holders of each Class of
Certificates affected thereby evidencing not less than 51% of the Voting Rights
of such Class for the purpose of adding any provisions to or changing in any

                                      135
<PAGE>

manner or eliminating any of the provisions of this Agreement or of modifying
in any manner the rights of the Holders of Certificates; provided that no such
amendment shall (i) reduce in any manner the amount of, or delay the timing of,
payments required to be distributed on any Certificate without the consent of
the Holder of such Certificate, (ii) adversely affect in any material respect
the interests of the Holders of any Class of Certificates in a manner other
than as described in (i), without the consent of the Holders of Certificates of
such Class evidencing 66% or more of the Voting Rights of such Class, or (iii)
reduce the aforesaid percentages of Certificates the Holders of which are
required to consent to any such amendment without the consent of the Holders of
all such Certificates then outstanding.

          Notwithstanding any contrary provision of this Agreement, Trustee and
the NIM Insurer shall not consent to any amendment to this Agreement unless
each shall have first received an Opinion of Counsel satisfactory to the
Trustee and the NIM Insurer, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee or the NIM Insurer, to the effect that such amendment will not cause
the imposition of any tax on the Trust Fund or the Certificateholders or cause
any REMIC formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

          Promptly after the execution of any amendment to this Agreement, the
Trustee shall furnish written notification of the substance of such amendment
to each Certificateholder (if the consent of Certificateholders is required)
and each Rating Agency.

          It shall not be necessary for the consent of Certificateholders under
this Section to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

          Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel, reasonably satisfactory to
the Trustee and the NIM Insurer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any Certificateholder

          Section 10.03 Governing Law.
                        --------------

          THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND
TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED
IN ACCORDANCE WITH SUCH LAWS.

          Section 10.04 Intention of Parties.
                        ---------------------

          It is the express intent of the parties hereto that the conveyance of
the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance
policies and any modifications, extensions and/or assumption agreements and
private mortgage insurance policies relating to the Mortgage Loans by the
Depositor to the Trustee be, and be construed as, an absolute sale thereof to
the Trustee. It is, further, not the intention of the parties that such
conveyance be deemed a pledge thereof by the Depositor to the Trustee. However,
in the event that, notwithstanding the intent of the parties, such assets are
held to be the property of the Depositor, or if for any other reason this
Agreement or any Subsequent Transfer Agreement is held or deemed to create a
security interest in such assets, then (i) this Agreement shall be deemed to be
a security agreement (within the meaning of the Uniform Commercial Code of the
State of New York) with respect to all such assets and security interests and
(ii) the conveyance provided for in this Agreement and any Subsequent Transfer
Agreement shall be deemed to be an assignment and a grant pursuant to the terms
of this Agreement by the Depositor to the Trustee, for the benefit of the
Certificateholders, of a security interest in all of the assets that constitute
the Trust Fund, whether now owned or hereafter acquired.

          The Depositor for the benefit of the Certificateholders and the NIM
Insurer shall, to the extent consistent with this Agreement, take such actions
as may be necessary to ensure that, if this Agreement were deemed to create a
security interest in the assets of the Trust Fund, such security interest would
be deemed to be a perfected security interest of first priority under
applicable law and will be maintained as such throughout the term of the
Agreement. The Depositor shall arrange for filing any Uniform Commercial Code
continuation statements in connection with any security interest granted or
assigned to the Trustee for the benefit of the Certificateholders.

          Section 10.05 Notices.

          Section 10.06 Severability of Provisions.
                        ---------------------------

          If any one or more of the covenants, agreements, provisions or terms
of this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and
shall in no way affect the validity or enforceability of the other provisions
of this Agreement or of the Certificates or the rights of the Holders thereof.

          Section 10.07 Assignment.
                        -----------

          Notwithstanding anything to the contrary contained herein, except as

Master Servicer without the prior written consent of the Trustee and the
Depositor.

          Section 10.08 Limitation on Rights of Certificateholders.
                        -------------------------------------------

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

          No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth or contained in the terms of the Certificates be construed so as to
constitute the Certificateholders from time to time as partners or members of
an association; nor shall any Certificateholder be under any liability to any
third party by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as hereinbefore
provided, the Holders of Certificates evidencing not less than 25% of the
Voting Rights shall also have made written request to the Trustee to institute
such action, suit or proceeding in its own name as Trustee hereunder and shall
have offered to the Trustee such reasonable indemnity as it may require against
the costs, expenses, and liabilities to be incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity shall have neglected or refused to institute any such action, suit or
proceeding; it being understood and intended, and being expressly covenanted by
each Certificateholder with every other Certificateholder and the Trustee, that
no one or more Holders of Certificates shall have any right in any manner
whatever by virtue or by availing itself or themselves of any provisions of
this Agreement to affect, disturb or prejudice the rights of the Holders of any
other of the Certificates, or to obtain or seek to obtain priority over or
preference to any other such Holder or to enforce any right under this
Agreement, except in the manner herein provided and for the common benefit of
all Certificateholders. For the protection and enforcement of the provisions

                                      139
<PAGE>

of this Section 10.08, each and every Certificateholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

          Section 10.09 Inspection and Audit Rights.
                        ----------------------------

          The Master Servicer agrees that, on reasonable prior notice, it will
permit any representative of the Depositor, any Seller, the NIM Insurer or the
Trustee during the Master Servicer's normal business hours, to examine all the
books of account, records, reports and other papers of the Master Servicer
relating to the Mortgage Loans, to make copies and extracts therefrom, to cause
such books to be audited by independent certified public accountants selected
by the Depositor, a Seller, the NIM Insurer or the Trustee and to discuss its
affairs, finances and accounts relating to the Mortgage Loans with its
officers, employees and independent public accountants (and by this provision
the Master Servicer hereby authorizes such accountants to discuss with such
representative such affairs, finances and accounts), all at such reasonable
times and as often as may be reasonably requested. Any out-of-pocket expense
incident to the exercise by the Depositor, any Seller, the NIM Insurer or the
Trustee of any right under this Section 10.09 shall be borne by the party
requesting such inspection; all other such expenses shall be borne by the
Master Servicer.

          Section 10.10 Certificates Nonassessable and Fully Paid.
                        ------------------------------------------

          It is the intention of the Depositor that Certificateholders shall
not be personally liable for obligations of the Trust Fund, that the interests
in the Trust Fund represented by the Certificates shall be nonassessable for
any reason whatsoever, and that the Certificates, upon due authentication
thereof by the Trustee pursuant to this Agreement, are and shall be deemed
fully paid.

          Section 10.11 Rights of NIM Insurer.
                        ----------------------

          (a)     The rights of the NIM Insurer under this Agreement shall
exist only so long as either:

                  (1) the notes certain payments on which are guaranteed by the
          NIM Insurer remain outstanding or

                  (2) the NIM Insurer is owed amounts paid by it with respect
          to that guaranty.

          (b)     The rights of the NIM Insurer under this Agreement are
exercisable by the NIM Insurer only so long as no default by the NIM Insurer
under its guaranty of certain payments under notes backed or secured by the
Class C or Class P Certificates has occurred and is continuing. If the NIM
Insurer is the subject of any insolvency proceeding, the rights of the NIM
Insurer under this Agreement will be exercisable by the NIM Insurer only so
long as:

                  (1) the obligations of the NIM Insurer under its guaranty of
          notes backed or secured by the Class C or Class P Certificates have
          not been disavowed and

                                      140
<PAGE>

                  (2) CHL and the Trustee have received reasonable assurances
          that the NIM Insurer will be able to satisfy its obligations under
          its guaranty of notes backed or secured by the Class C or Class P
          Certificates.

          (c)     The NIM Insurer is a third party beneficiary of this
Agreement to the same extent as if it were a party to this Agreement and may
enforce any of those rights under this Agreement.

          (d)     A copy of any documents of any nature required by this
Agreement to be delivered by the Trustee, or to the Trustee or the Rating
Agencies, shall in each case at the same time also be delivered to the NIM
Insurer. Any notices required to be given by the Trustee, or to the Trustee or
the Rating Agencies, shall in each case at the same time also be given to the
NIM Insurer. If the Trustee receives a notice or document that is required
hereunder to be delivered to the NIM Insurer, and if such notice or document
does not indicate that a copy thereof has been previously sent to the NIM
Insurer, the Trustee shall send the NIM Insurer a copy of such notice or
document. If such document is an Opinion of Counsel, the NIM Insurer shall be
an addressee thereof or such Opinion of Counsel shall contain language
permitting the NIM Insurer to rely thereon as if the NIM Insurer were an
addressee thereof.

          (e)     Anything in this Agreement that is conditioned on not
resulting in the downgrading or withdrawal of the ratings then assigned to the
Certificates by the Rating Agencies shall also be conditioned on not resulting
in the downgrading or withdrawal of the ratings then assigned by the Rating
Agencies to the notes backed or secured by the Class C or Class P Certificate
(without giving effect to any policy or guaranty provided by the NIM Insurer).

STATE OF               )
                       )  ss.:
COUNTY OF              )

          The undersigned, being first duly sworn, deposes and says as
follows:

          1. The undersigned is an officer of _______________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, dated
as of March 1, 2005 (the "Agreement"), by and among CWABS, Inc., as depositor
(the "Depositor"), Countrywide Home Loans, Inc., as a Seller, Park Monaco
Inc., as a Seller, Park Sienna LLC, as a Seller, Countrywide Home Loans
Servicing LP, as Master Servicer, The Bank of New York Trust Company, N.A., as
Co-Trustee, and The Bank of New York, as Trustee. Capitalized terms used, but
not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to
such terms in the Agreement. The Transferee has authorized the undersigned to
make this affidavit on behalf of the Transferee.

          2. The Transferee is not an employee benefit plan that is subject to
Title I of ERISA or to section 4975 of the Internal Revenue Code of 1986, nor
is it acting on behalf of or with plan assets of any such plan. The Transferee
is, as of the date hereof, and will be, as of the date of the Transfer, a
Permitted Transferee. The Transferee will endeavor to remain a Permitted
Transferee for so long as it retains its Ownership Interest in the
Certificate. The Transferee is acquiring its Ownership Interest in the
Certificate for its own account.

          3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are not
Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if
such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability
for the tax if the subsequent Transferee furnished to such Person an affidavit
that such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

          4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the
pass-through entity does not have actual knowledge that such affidavit is
false. (For this purpose, a "pass-through entity" includes a regulated
investment company, a real estate investment trust or common trust fund, a
partnership, trust or estate, and certain cooperatives and, except as may be
provided in Treasury Regulations, persons holding interests in pass-through
entities as a nominee for another Person.)

                                    I-1-1
<PAGE>

          5. The Transferee has reviewed the provisions of Section 5.02(c) of
the Agreement (attached hereto as Exhibit 2 and incorporated herein by
reference) and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by
and to abide by the provisions of Section 5.02(c) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

          6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in
the Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit J-1 to the Agreement (a "Transferor Certificate") to
the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

          7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect
to the Class A-R Certificates.

          8. The Transferee's taxpayer identification number is _____.

          9. The Transferee is a U.S. Person as defined in Code section
7701(a)(30).

          10. The Transferee is aware that the Class A-R Certificates may be
"noneconomic residual interests" within the meaning of proposed Treasury
regulations promulgated pursuant to the Code and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with
respect to the income on such residual interest, unless no significant purpose
of the transfer was to impede the assessment or collection of tax. In
addition, as the holder of a noneconomic residual interest, the Transferee may
incur tax liabilities in excess of any cash flows generated by the interest
and the Transferee hereby represents that it intends to pay taxes associated
with holding the residual interest as they become due.

          11. The Transferee has provided financial statements or other
financial information requested by the Transferor in connection with the
transfer of the Class A-R Certificates to permit the Transferor to assess the
financial capability of the Transferee to pay such taxes.

                                  *    *    *

     5.02(c), then the last preceding Permitted Transferee shall be restored
     to all rights as Holder thereof retroactive to the date of registration
     of Transfer of such Class A-R Certificate. The Trustee shall be under no
     liability to any Person for any registration of Transfer of a Class A-R
     Certificate that is in fact not permitted by Section 5.02(b) and this
     Section 5.02(c) or for making any payments due on such Certificate to the
     Holder thereof or taking any other action with respect to such Holder
     under the provisions of this Agreement so long as the Transfer was
     registered after receipt of the related Transfer Affidavit and Transferor
     Certificate. The Trustee shall be entitled but not obligated to recover
     from any Holder of a Class A-R Certificate that was in fact not a
     Permitted Transferee at the time it became a Holder or, at such
     subsequent time as it became other than a Permitted Transferee, all
     payments made on such Class A-R Certificate at and after either such
     time. Any such payments so recovered by the Trustee shall be paid and
     delivered by the Trustee to the last preceding Permitted Transferee of
     such Certificate.

          (5) The Master Servicer shall use its best efforts to make
     available, upon receipt of written request from the Trustee, all
     information necessary to compute any tax imposed under section 860E(e) of
     the Code as a result of a Transfer of an Ownership Interest in a Class
     A-R Certificate to any Holder who is not a Permitted Transferee.

          The restrictions on Transfers of a Class A-R Certificate set forth
in this section 5.02(c) shall cease to apply (and the applicable portions of
the legend on a Class A-R Certificate may be deleted) with respect to
Transfers occurring after delivery to the Trustee of an Opinion of Counsel,
which Opinion of Counsel shall not be an expense of the Trustee, the Sellers
or the Master Servicer to the effect that the elimination of such restrictions
will not cause any constituent REMIC of any REMIC formed hereunder to fail to
qualify as a REMIC at any time that the Certificates are outstanding or result
in the imposition of any tax on the Trust Fund, a Certificateholder or another
Person. Each Person holding or acquiring any ownership Interest in a Class A-R
Certificate hereby consents to any amendment of this Agreement that, based on
an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to
ensure that the record ownership of, or any beneficial interest in, a Class
A-R Certificate is not transferred, directly or indirectly, to a Person that
is not a Permitted Transferee and (b) to provide for a means to compel the
Transfer of a Class A-R Certificate that is held by a Person that is not a
Permitted Transferee to a Holder that is a Permitted Transferee.

        ___    Business Development Company. Buyer is a business development
               company as defined in Section 202(a)(22) of the Investment
               Advisors Act of 1940.

     The term "securities" as used herein does not include (i) securities of
        issuers that are affiliated with the Buyer, (ii) securities that are
        part of an unsold allotment to or subscription by the Buyer, if the
        Buyer is a dealer, (iii) securities issued or guaranteed by the U.S.
        or any instrumentality thereof, (iv) bank deposit notes and

        agreement and (viii) currency, interest rate and commodity swaps.

     For purposes of determining the aggregate amount of securities owned

        the cost of such securities to the Buyer and did not include any of
        the securities referred to in the preceding paragraph, except (i)
        where the Buyer reports its securities holdings in its financial
        statements on the basis of their market value, and (ii) no current
        information with respect to the cost of those securities has been
        published. If clause (ii) in the preceding sentence applies, the
        securities may be valued at market. Further, in determining such
        aggregate amount, the Buyer may have included securities owned by
        subsidiaries of the Buyer, but only if such subsidiaries are
        consolidated with the Buyer in its financial statements prepared in
        accordance with generally accepted accounting principles and if the
        investments of such subsidiaries are managed under the Buyer's
        direction. However, such securities were not included if the Buyer is
        a majority-owned, consolidated subsidiary of another enterprise and
        the Buyer is not itself a reporting company under the Securities
        Exchange Act of 1934, as amended.

     The Buyer acknowledges that it is familiar with Rule 144A and understands
        that the seller to it and other parties related to the Certificates
        are relying and will continue to rely on the statements made herein
        because one or more sales to the Buyer may be in reliance on Rule
        144A.

                                     L-4
<PAGE>

     Until the date of purchase of the Rule 144A Securities, the Buyer will
        notify each of the parties to which this certification is made of any
        changes in the information and conclusions herein. Until such notice
        is given, the Buyer's purchase of the Certificates will constitute a
        reaffirmation of this certification as of the date of such purchase.
        In addition, if the Buyer is a bank or savings and loan is provided
        above, the Buyer agrees that it will furnish to such parties updated
        annual financial statements promptly after they become available.

           QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
           --------------------------------------------------------

          [For Transferees That are Registered Investment Companies]

The undersigned (the "Buyer") hereby certifies as follows to the parties
listed in the Rule 144A Transferee Certificate to which this certification
relates with respect to the Certificates described therein:

          1. As indicated below, the undersigned is the President, Chief
Financial Officer or Senior Vice President of the Buyer or, if the Buyer is a
"qualified institutional buyer" as that term is defined in Rule 144A under the
Securities Act of 1933, as amended ("Rule 144A") because Buyer is part of a
Family of Investment Companies (as defined below), is such an officer of the
Adviser.

     In connection with purchases by Buyer, the Buyer is a "qualified
        institutional buyer" as defined in SEC Rule 144A because (i) the Buyer
        is an investment company registered under the Investment Company Act
        of 1940, as amended and (ii) as marked below, the Buyer alone, or the
        Buyer's Family of Investment Companies, owned at least $100,000,000 in
        securities (other than the excluded securities referred to below) as
        of the end of the Buyer's most recent fiscal year. For purposes of
        determining the amount of securities owned by the Buyer or the Buyer's
        Family of Investment Companies, the cost of such securities was used,
        except (i) where the Buyer or the Buyer's Family of Investment
        Companies reports its securities holdings in its financial statements
        on the basis of their market value, and (ii) no current information
        with respect to the cost of those securities has been published. If
        clause (ii) in the preceding sentence applies, the securities may be
        valued at market.

        ___    The Buyer owned $ in securities (other than the excluded
               securities referred to below) as of the end of the Buyer's most
               recent fiscal year (such amount being calculated in accordance
               with Rule 144A).

        ___    The Buyer is part of a Family of Investment Companies which
               owned in the aggregate $ in securities (other than the excluded
               securities referred to below) as of the end of the Buyer's most
               recent fiscal year (such amount being calculated in accordance
               with Rule 144A).

     The term "Family of Investment Companies" as used herein means two or
        more registered investment companies (or series thereof) that have the
        same investment adviser or investment advisers that are affiliated (by
        virtue of being majority owned subsidiaries of the same parent or
        because one investment adviser is a majority owned subsidiary of the
        other).

     The term "securities" as used herein does not include (i) securities of
        issuers that are affiliated with the Buyer or are part of the Buyer's
        Family of Investment Companies, (ii) securities issued or guaranteed
        by the U.S. or any instrumentality thereof, (iii) bank deposit notes
        and certificates of deposit, (iv) loan participations, (v) repurchase

<PAGE>

        agreements, (vi) securities owned but subject to a repurchase
        agreement and (vii) currency, interest rate and commodity swaps.

     The Buyer is familiar with Rule 144A and under-stands that the parties
        listed in the Rule 144A Transferee Certificate to which this
        certification relates are relying and will continue to rely on the
        statements made herein because one or more sales to the Buyer will be
        in reliance on Rule 144A. In addition, the Buyer will only purchase
        for the Buyer's own account.

     Until the date of purchase of the Certificates, the undersigned will
        notify the parties listed in the Rule 144A Transferee Certificate to
        which this certification relates of any changes in the information and
        conclusions herein. Until such notice is given, the Buyer's purchase
        of the Certificates will constitute a reaffirmation of this
        certification by the undersigned as of the date of such purchase.
