            The Depositor is the owner of the Trust Fund that is hereby
conveyed to the Trustee in return for the Certificates. The Trust Fund
(excluding the Credit Comeback Excess Account, the Carryover Reserve Fund, the

tax purposes will consist of four REMICs ("REMIC 1," "REMIC 2," "REMIC 3" and
the "Master REMIC"). Each Certificate, other than the Class A-R Certificate,
will represent ownership of one or more regular interests in the Master REMIC
for purposes of the REMIC Provisions. The Class A-R Certificate represents
ownership of the sole class of residual interest in REMIC 1, REMIC 2, REMIC 3
and the Master REMIC. The Master REMIC will hold as assets the several classes
of uncertificated REMIC 3 Interests (other than the R-3-R Interest). Each
REMIC 3 Interest (other than the R-3-R Interest) is hereby designated as a
regular interest in REMIC 3. REMIC 3 will hold as assets the several classes
of REMIC 2 Interests (other than the R-2-R Interest). Each REMIC 2 Interest
(other than the R-2-R Interest) is hereby designated as a regular interest in

(other than the R-1-R Interest). Each REMIC 1 Interest (other than the R-1-R
Interest) is hereby designated as a regular interest in REMIC 1. REMIC 1 will
hold as assets all property of the Trust Fund (excluding the Credit Comeback
Excess Account, the Carryover Reserve Fund, the assets held in the Pre-Funding
Account and the Trust Fund's rights with respect to payments received under
the Corridor Contracts). The latest possible maturity date of all REMIC
regular interests created in this Agreement shall be the Latest Possible

            (1)   The principal balance of each REMIC 1 Interest having an "I"
                  designation is the principal balance of all the Initial
                  Mortgage Loans in the Corresponding Loan Group.

            (2)   The principal balance of each REMIC 1 Interest having an "S"
                  designation is the principal balance of all the Subsequent
                  Mortgage Loans in the Corresponding Loan Group.

            (3)   This REMIC 1 Interest pays no principal.

            (4)   The R-1-R Interest is the sole class of residual interest in
                  REMIC 1. It has no principal balance and pays no principal
                  or interest.

            (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 March 2006 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
                  March 2006, the interest rate for this REMIC 1 Interest is a
                  per annum rate equal to the weighted average of the Adjusted
                  Net Mortgage Rates of all the Mortgage Loans in the
                  Corresponding Loan Group.

            (6)   The interest rate for this REMIC 1 Interest with respect to
                  any Distribution Date (and the related Accrual Period)
                  through the Distribution Date in March 2006 is a per annum
                  rate equal to 0.00%. For any Distribution Date (and the
                  related Accrual Period) following the Distribution Date in
                  March 2006, the interest rate for this REMIC 1 Interest is a
                  per annum rate equal to the weighted average of the Adjusted
                  Net Mortgage Rates of all the Mortgage Loans in the
                  Corresponding Loan Group.

            (7)   For any Distribution Date (and the related Accrual Period)
                  through the Distribution Date in March 2006, this REMIC 1
                  Interest is entitled to all the interest payable with
                  respect to the Subsequent Mortgage Loans in the
                  Corresponding Loan Group (or Groups). For any Distribution
                  Date (and the related Accrual Period) following the
                  Distribution Date in March 2006, the interest rate for this
                  REMIC 1 Interest is a per annum rate equal to 0.00%.

            (8)   The R-1-P Interest is entitled to all Prepayment Charges
                  collected with respect to the Mortgage Loans. It pays no

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 March 2006, the Principal
Distribution Amount with respect to the Initial Mortgage Loans in a Loan Group
shall be allocated to its corresponding "I" REMIC 1 Interests, and the
Principal Distribution Amount with respect to the Subsequent Mortgage Loans in
a Loan Group shall be allocated to its corresponding "S" REMIC 1 Interests.
For any Distribution Date (and the related Accrual Period) after the

            (1)   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 2 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. The initial principal
                  balance of each REMIC 2 Interest having an "R-2-C-"
                  designation (each, an "R-2-C Interest") will equal the
                  excess of its Corresponding Loan Group over the initial
                  aggregate principal balances of the R-2-A and R-2-B
                  Interests corresponding to such Loan Group.

            (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)   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").

            (4)   The R-2-P Interest is entitled to all amounts payable with
                  respect to the R-1-P Interest. It pays no interest.

            (5)   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.

            (6)   This REMIC 2 Interest pays no principal.

            (7)   This REMIC 2 Interest is entitled to all amounts payable
                  with respect to the R-1-X 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 if no Cross-Over Situation Exists. If no Cross-Over
Situation exists with respect to any REMIC 2 Interest, then the Principal
Distribution Amounts payable with respect to each Loan Group will be payable:
first to cause the Loan Group's corresponding R-2-A and R-2-B Interests to
equal, respectively, 0.9% of the SCB and 0.1% of the SCB, and then to the
corresponding R-2-C Interest.

      (3) 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 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 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 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 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 Subordinate Net Rate Cap. With respect to each 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


                                      4
<PAGE>


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 Loan Group's R-2-C Interest.

      (c) The outstanding aggregate R-2-A and R-2-B Interests for both Loan
Groups will not be reduced below 1 percent of the excess of (i) the aggregate
outstanding Stated Principal Balances of all Loan Groups as of the end of any
Due Period over (ii) the Senior Certificates related to the 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 Loan Group,
and if the Loan Group's corresponding R-2-C Interest has already been reduced
to zero, then the excess principal from that Loan Group will be paid to the
R-2-C Interest of the other Loan Group, the aggregate R-2-A and R-2-B
Interests of which are less than one percent of the Subordinate Component
Balance. If the Loan Group of the corresponding R-2-C Interest that receives
such payment has a Group Net Rate Cap below the Group Net Rate Cap of the Loan
Group making the payment, then the payment will be treated by REMIC 2 as a
Realized Loss. Conversely, if the Loan Group of the R-2-C Interest that
receives such payment has a Group Net Rate Cap above the Group Net Rate Cap of
the Loan Group making the payment, then the payment will be treated by REMIC 2
as a reimbursement for prior Realized Losses.

      REMIC 3:

The REMIC 3 Regular Interests will have the principal balances, pass-through
rates and Corresponding Classes of Certificates as set forth in the following

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 any ratings assigned to the
      Certificates by the Rating Agencies (without regard to the Class 1-AF-5
      Policy, in the case of the Class 1-AF-5 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 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


                                      58

      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;

                  (8) 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

                  (9) 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


                                      59
<PAGE>


      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)(1) and (e)(9), (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 and the Loan Group into which each Subsequent
Mortgage Loan was conveyed, (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)(6) and (7).

            (g) In connection with the transfer and assignment of each
Mortgage Loan, the Depositor has delivered to, and deposited with, the Trustee
(or, in the case of the Delay Delivery Mortgage Loans, will deliver to, and
deposit with, the 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


                                      60
<PAGE>

            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 and all such
            intervening endorsements;

                        (ii) in the case of each Mortgage Loan that is not a
            MERS Mortgage Loan, the original recorded Mortgage or a copy of
            such Mortgage, with recording information, and in the case of each
            MERS Mortgage Loan, the original Mortgage or a copy of such
            Mortgage, with recording information, noting the presence of the
            MIN of the Mortgage 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 2005-15, CWABS, Inc., by The
            Bank of New York, a New York banking corporation, as trustee under
            the Pooling and Servicing Agreement dated as of December 1, 2005,
            without recourse" or a copy of such assignment, with recording
            information, (each such assignment, when duly and validly
            completed, to be in recordable form and sufficient to effect the
            assignment of and transfer to the assignee thereof, under the
            Mortgage to which such assignment relates);

                        (iv) the original recorded assignment or assignments
            of the Mortgage or a copy of such assignments, with recording
            information, together with all interim recorded assignments of
            such Mortgage or a copy of such assignments, with recording
            information (in each case 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 copy of 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


                                      61
<PAGE>


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 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 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 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 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 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 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


                                      62
<PAGE>


in clause (iii) above is not necessary to protect the Trustee's, 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 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 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 Trustee shall complete the
assignment in the manner specified in clause (iii) above 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) above.

            So long as the Trustee or its agent maintains an office in the
State of California, the 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 preceding 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 Trustee the Mortgage File as required pursuant to this


                                      63
<PAGE>


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.

            Section 2.02 Acceptance by Trustee of the Mortgage Loans.

            (a) The 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 and
the Class 1-AF-5 Insurer.

            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 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
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


                                      64
<PAGE>


their face and relate to such Initial Mortgage Loan, and (ii) the information
set forth in items (i), (iv), (v), (vi), (viii), (ix) and (xv) 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 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 Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller), the Class 1-AF-5 Insurer 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 Trustee 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 and all such intervening endorsements;

                        (ii) in the case of each Initial Mortgage Loan that is
            not a MERS Mortgage Loan, the original recorded Mortgage or a copy
            of such Mortgage, with recording information, and in the case of
            each Initial Mortgage Loan that is a MERS Mortgage Loan, the
            original Mortgage or a copy of such Mortgage, with recording
            information, noting the presence of the MIN of the 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 (on its own behalf and on behalf of Park Monaco and

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 Initial Mortgage Loan shall be

and regulations.

            The Trustee shall retain possession and custody of each Mortgage

herein. Each Seller shall promptly deliver to the 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 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

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

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

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

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


                                      67
<PAGE>


face and relate to such Subsequent Mortgage Loan, and (ii) the information set
forth in items (i), (iv), (v), (vi), (viii), (ix) and (xv) of the definition

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.

      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

      copy of such assignments, with recording information (in each case
      noting the presence of a MIN in the case of each MERS Mortgage Loan);

                  (v) the original or copies of each assumption, modification,

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

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

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.

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 Depositor and any Certificateholder
against the Sellers.

      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.

                  (13) There is no delinquent tax or assessment lien against
      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


                                      74
<PAGE>

      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.

                  (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


                                      75
<PAGE>


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

                  (33) Each Initial Mortgage Loan in Loan Group 1 and Loan
      Group 2 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, a Three-Year
      Hybrid Mortgage Loan or a Five-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; 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; and each Initial Mortgage Loan that is a Five-Year

                                      76
<PAGE>


                  (35) Approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group 1 and
      Loan Group 2 provide for a Prepayment Charge.

                  (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 and Loan Group 2, 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
      and Loan Group 2 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 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


                                      77
<PAGE>

      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.


                                      78
<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
      in Loan Group 1 and Loan Group 2 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 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.

                  (50) The Gross Margins on the Initial Mortgage Loans in Loan
      Group 1 and Loan Group 2 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.

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

                  (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


                                      79
<PAGE>


      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. No borrower obtained a prepaid
      single-premium credit life, disability, 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.


                                      80

                  (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.

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

                  (65) 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 or any similar state or
      local law.

                  (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
      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.

                  (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,
      state and federal laws, including, but not limited to, all predatory and
      abusive lending laws.

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

                  (70) Each Prepayment Charge is enforceable and was

      laws.

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

                  (73) 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 & Poor's LEVELS(R) Glossary which is now Version
      5.6(c), Appendix E) and no Mortgage Loan originated on or after October
      1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending
      Act.

      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.

                  (75) No Mortgage Loan in the Trust Fund is a "high cost
      home," "covered" (excluding home loans defined as "covered home loans"
      in the New Jersey Home Ownership Security Act of 2002 that were
      originated between November 26, 2003 and July 7, 2004), "high risk home"
      or "predatory" loan under any applicable state, federal or local law (or
      a similarly classified loan using different terminology under a law
      imposing heightened regulatory scrutiny or additional legal liability
      for residential mortgage loans having high interest rates, points and/or
      fees).

                  (76) There is no Mortgage Loan in the Trust Fund that was
      originated on or after October 1, 2002 and before March 7, 2003, which
      is secured by property located in the State of Georgia.

                  (77) [Reserved.]

                  (78) The representations in Section 2.03(c)(1)-(6) and
      2.03(d)(1)-(6) are true and correct.

      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.

            (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 or
the Class 1-AF-5 Insurer in any Mortgage Loan, the party discovering such
breach shall give prompt notice thereof to the other parties, the NIM Insurer,
the Class 1-AF-5 Insurer and the Swap Counterparty. 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 1-AF-5 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


                                      85
<PAGE>


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 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) or (b)(76)
shall be deemed to materially and adversely affect the Certificateholders.
With respect to a breach of a representation of Park Monaco or Park Sienna, if
that Seller fails to cure the breach or repurchase the affected Mortgage Loan
within the time period required by Section 2.03(c) hereunder, CHL hereby
agrees to honor that Seller's obligations as set forth in this Section.

            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


                                      86
<PAGE>


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
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.

            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 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 Trustee
for the benefit of the Certificateholders with respect to each Mortgage Loan.

      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 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

      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

      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,

Mortgage Loan to it by the Sellers, the Depositor had good title to the

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, the NIM
Insurer, the Class 1-AF-5 Insurer and the Swap Counterparty. 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 by 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 or the Class 1-AF-5 Insurer 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).

            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 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.


                                      89

            (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.

            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,


                                      90
<PAGE>


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 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.


                                      91
<PAGE>


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

            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 1-AF-5 Policy in the case of the Class 1-AF-5
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


                                      92
<PAGE>


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 1-AF-5
                         Insurer and the Trustee in Respect of the Master
                         Servicer.

            None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer, the Class 1-AF-5 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 Class 1-AF-5 Insurer, 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 Class 1-AF-5 Insurer, 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, the Class
1-AF-5 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
1-AF-5 Insurer, the NIM Insurer or the Trust Fund, and in either case, the
Depositor, the NIM Insurer, the Class 1-AF-5 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


                                      93
<PAGE>


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; 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


                                      94
<PAGE>


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 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


                                      95
<PAGE>


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 January, February and March 2006,
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) If the Pre-Funded Amount is greater than zero, the Trustee
shall establish and maintain, on behalf of the Certificateholders, the
Pre-Funding Account, and 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


                                      96
<PAGE>


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 the Depositor and shall be remitted to the Depositor 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 the Master
Servicer to the Trustee for deposit into the Pre-Funding Account out of the
Master Servicer'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


                                      97
<PAGE>


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,
the Class 1-AF-5 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.

            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

                                      98
<PAGE>

            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 Purchase Price 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;


                                      99
<PAGE>



                        (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 $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 $100.00 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), (viii) and (ix) 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 1-AF-5 Insurer and
remittance to the Swap Account 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;


                                     100
<PAGE>


                        (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.

            (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


                                     101
<PAGE>



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. If the hazard policy contains a deductible
clause, the Master Servicer will be required to deposit from its own funds
into the Certificate Account the amounts that would have been deposited
therein but for the deductible clause.

            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


                                     102
<PAGE>


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
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 Certai nMortgage Loans.

            (a) The Master Servicer may agree to a modification of any
Mortgage Loan (the "Modified Mortgage Loan") if (i) CHL purchases the Modified
Mortgage Loan from the Trust Fund immediately following the modification as
described below and (ii) the Stated Principal Balance of such Mortgage Loan,
when taken together with the aggregate of the Stated Principal Balances of all
other Mortgage Loans in the same Loan Group that have been so modified since
the Closing Date at the time of those modifications, does not exceed an amount
equal to 5% of the aggregate Certificate Principal Balance of the related
Certificates. Effective


                                     103
<PAGE>


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 CHL 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 CHL. 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. CHL shall remit the Purchase Price to the Master Servicer for deposit
into 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 CHL or its designee 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 CHL any Modified
Mortgage Loan previously transferred and assigned pursuant hereto. CHL
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 (a), any
holding of a Modified Mortgage Loan by the Trust Fund or any purchase of a
Modified Mortgage Loan by CHL (but such obligation shall not prevent CHL or
any other appropriate Person from in good faith contesting any such tax in
appropriate proceedings and shall not prevent the CHL from withholding payment
of such tax, if permitted by law, pending the outcome of such proceedings).
CHL 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 CHL. 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, CHL shall 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


                                     104
<PAGE>


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 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


                                     105
<PAGE>


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.

            (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


                                     106
<PAGE>


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 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 Trustee by delivering a Request for File Release. Upon receipt of such
request, the Trustee shall promptly release the related Mortgage File to the
Master Servicer, and the 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 Trustee shall, upon delivery to the 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 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 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


                                     107
<PAGE>


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 Trustee to be returned to the Trustee within 21 calendar
days after possession thereof shall have been released by the 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 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 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 or the Class
1-AF-5 Insurer, 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


                                     108
<PAGE>


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
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 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 transaction 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 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 Certificate Principal Balance of the Class 1-AF-1 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 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 Class 1-AF-1
Certificates as provided in Section 4.04(c) 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 4.07 until such Corridor Contract


                                     110
<PAGE>


Termination Date. On the Corridor Contract Termination Date, after all other
distributions on such date, if any such amount in respect of early termination
of the Corridor Contract remains 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 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 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


                                     111
<PAGE>


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.

            Section 3.21 Swap Contract.

            CHL shall cause The Bank of New York to enter into the Swap
Contract Administration Agreement and shall assign all of its right, title and
interest in and to the interest rate swap transaction evidenced by the Swap
Contract to, and shall cause all of its obligations in respect of such
transaction to be assumed by, the Swap Contract Administrator, on the terms
and conditions set forth in the Swap Contract Assignment Agreement. The
Trustee's rights to receive certain proceeds of the Swap Contract as provided
in the Swap Contract Administration Agreement shall be rights of the Trustee
as Swap Trustee hereunder, shall be an asset of the Swap Trust and shall not
be an asset of the Trust Fund nor of any REMIC. The Swap Trustee shall deposit
any amounts received from time to time from the Swap Contract Administrator
with respect to the Swap Contract into the Swap Account. The Master Servicer
shall deposit any amounts received on behalf of the Swap Trustee from time to
time with respect to the Swap Contract into the Swap Account.

            On the Business Day preceding each Distribution Date, the Swap
Trustee shall notify the Swap Contract Administrator of any amounts
distributable to the Swap Certificates pursuant to Section 4.04(d)(3) through
(8) that will remain unpaid following all distributions to be made on such
Distribution Date pursuant to Section 4.04(a) through (c).

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

            Upon the Swap Contract Administrator obtaining actual knowledge of
the rating of the Swap Counterparty falling below the Approved Rating
Thresholds (as defined in the Swap Contract), the Swap Trustee shall direct
the Swap Contract Administrator to demand payment of the Delivery Amount (as
defined in the ISDA Credit Support Annex). If a Delivery Amount is demanded,
the Swap Trustee shall set up an account in accordance with Section 4.09 to
hold cash or other eligible investments pledged under the ISDA Credit Support
Annex. Any cash or other eligible investments pledged under the ISDA Credit
Support Annex shall not be part of the Distribution Account or the Swap
Account unless they are applied in accordance with the ISDA Credit Support
Annex to make a payment due to the Swap Contract Administrator pursuant to the
Swap Contract.

            Upon the Swap Trustee obtaining actual knowledge of a Failure to
Pay or Deliver (as defined in the Swap Contract), the Swap Trustee shall
direct the Swap Contract Administrator to demand payment under the Swap
Guarantee.

            Upon the Swap Trustee obtaining actual knowledge of an Event of
Default (as defined in the Swap Contract) or Termination Event (as defined in
the Swap Contract) for which the Swap Contract Administrator has the right to
designate an Early Termination Date (as


                                     112
<PAGE>


defined in the Swap Contract), the Swap Trustee shall act at the written
direction of the Depositor as to whether to direct the Swap Contract
Administrator to designate an Early Termination Date; provided, however, that
the Swap Trustee shall provide written notice to each Rating Agency following
the Event of Default or Termination Event. Upon the termination of the Swap
Contract under the circumstances contemplated by this Section 3.21, the Swap
Trustee shall use its reasonable best efforts to enforce the rights of the
Swap Contract Administrator as may be permitted by the terms of the Swap
Contract and consistent with the terms hereof, and CHL shall assist the Swap
Contract Administrator in procuring a replacement swap contract with terms
approximating those of the original Swap Contract.

            In the event that the swap counterparty in respect of a
replacement swap contract pays any upfront amount to the Swap Contract
Administrator in connection with entering into the replacement swap contract,
the Swap Trustee shall notify the Swap Contract Administrator of the amount of
Interest Funds for Loan Group 1 and Loan Group 2 and the Principal
Distribution Amounts for Loan Group 1 and Loan Group 2 that were used on prior
Distribution Dates to cover any Swap Termination Payment due to the Swap
Counterparty under the original Swap Contract, and any portion of such upfront
amount paid by a swap counterparty in respect of a replacement swap contract
that is remitted by the Swap Contract Administrator to the Swap Trustee shall
be included in Interest Funds for Loan Group 1 and Loan Group 2 and the
Principal Distribution Amounts for Loan Group 1 and Loan Group 2 on the next
Distribution Date to the extent, and in the respective amounts, that such
Interest Funds for Loan Group 1 and Loan Group 2 and Principal Distribution
Amounts for Loan Group 1 and Loan Group 2 were used on prior Distribution
Dates to cover any Swap Termination Payment due to the Swap Counterparty under
the original Swap Contract.

            Any portion of any Net Swap Payment or Swap Termination Payment
payable by the Swap Counterparty and not remitted by the Swap Contract
Administrator to the Swap Trustee with respect to any Distribution Date will
be remitted to CHL and will not be available to make distributions in respect
of any Class of Certificates.

            The Swap Counterparty shall be an express third party beneficiary
of this Agreement for the purpose of enforcing the provisions hereof to the
extent of the Swap Counterparty's rights explicitly specified herein as if a
party hereto.

                                 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.


                                     113
<PAGE>


            (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 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 becomes a Liquidated Mortgage Loan
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


                                     114
<PAGE>


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

                (5) to the Holders of the Class or Classes of Swap Certificates
      then entitled to receive distributions in respect of principal, in an
      aggregate amount equal to the Overcollateralization Deficiency Amount
      remaining unpaid following the distribution of Excess Cashflow and
      Credit Comeback Excess Cashflow as described above under Section
      4.04(c), payable to such Holders of each such Class in the same manner

                (6) to the Holders of each Class of Swap Certificates, to the
      extent needed to pay any remaining Net Rate Carryover for each such

      Classes, in each case in an amount equal to the remaining Unpaid

the Trustee, acting on behalf of the Swap Trust, shall distribute any

            (e) On each Distribution Date on or prior to the Corridor Contract
Termination Date, amounts received by the Trustee in respect of the Corridor
Contract for such Distribution Date shall be withdrawn from the Carryover
Reserve Fund and distributed to the Class 1-AF-1 Certificates to the extent
needed to pay any Net Rate Carryover with respect to such Class. Any amounts
remaining in the Carryover Reserve Fund in respect of the Corridor Contract
shall be distributed to the Holders of the Class C Certificates as provided in
Section 4.07(c).

            (f) To the extent that a Class of Interest-Bearing Certificates
receives interest in excess of the applicable Net Rate Cap, if such interest
is paid pursuant to Section 4.04(c), then it shall be deemed to have been paid
to the Carryover Reserve Fund and then paid by the Carryover Reserve Fund to
those Certificateholders, and if such interest is paid pursuant to Section
4.04(d), then such interest shall be deemed to have been paid to the Swap
Account and then paid by the Swap Account to those Certificateholders. For
purposes of the Code, amounts deemed deposited in the Carryover Reserve Fund
shall be deemed to have first been distributed to the Class C Certificates.

            (g) On each Distribution Date, all Prepayment Charges (including
amounts deposited in connection with the full or partial waiver of such
Prepayment Charges pursuant to Section 3.20) shall be allocated to the Class P

the Class B, Class M-8, Class M-7, Class M-6, Class M-5, Class M-4, Class M-3,
Class M-2 and Class M-1 Certificates, sequentially, in that order, in each

the Certificate Principal Balances of the Subordinate Certificates have been
reduced to zero, (i) the Trustee shall allocate any Applied Realized Loss
Amount with respect to Loan Group 1 to reduce the Certificate Principal
Balances of each Class of Class 1-AF Certificates, on a pro rata basis
according to their respective Certificate Principal Balances, until



                                     122
<PAGE>


the Certificate Principal Balances of such classes have been reduced to zero,
and (ii) the Trustee shall allocate any Applied Realized Loss Amount with
respect to Loan Group 2 to reduce the Certificate Principal Balances of each
Class of Class 2-AV Certificates, on a pro rata basis according to their
respective Certificate Principal Balances, until the Certificate Principal
Balances of such Classes have been reduced to zero.

            (i) On each Distribution Date, the Trustee shall allocate the
amount of the Subsequent Recoveries with respect to either Loan Group, if any,
first to increase the Certificate Principal Balances of the Class 1-AF
Certificates (in the case of any Subsequent Recoveries with respect to Loan
Group 1) or the Classes of Class 2-AV Certificates (in the case of any
Subsequent Recoveries with respect to Loan Group 2) to which Applied Realized
Loss Amounts have been previously allocated (such increases, in the case of
Subsequent Recoveries with respect to Loan Group 2, to be made among the
Classes of Class 2-AV Certificates on a pro rata basis according to their
respective Certificate Principal Balances), in each case by not more than the
amount of the Unpaid Realized Loss Amount of such Class, and then to increase
the Certificate Principal Balance of the Subordinate Certificates to which
Applied Realized Loss Amounts have been previously allocated, sequentially, to
the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class
M-7, Class M-8 and Class B Certificates, in that order, in each case by not
more than the amount of the Unpaid Realized Loss Amount of such Class;
provided, however, to the extent that an Applied Realized Loss Amount was
covered by the Class 1-AF-5 Policy, then any related Unpaid Realized Loss
Amount otherwise payable to the Class 1-AF-5 Certificateholders to this clause
shall instead be paid to the Class 1-AF-5 Insurer.

            (j) Holders of Certificates to which any Subsequent Recoveries
have been allocated shall not be entitled to any payment in respect of Current
Interest on the amount of such increases for any Accrual Period preceding the
Distribution Date on which such increase occurs.

            (k) Subject to Section 9.02 hereof respecting the final
distribution, on each Distribution Date the Trustee shall make distributions
to each Certificateholder of record on the preceding Record Date either by
wire transfer in immediately available funds to the account of such Holder at
a bank or other entity having appropriate facilities therefor, if (i) such

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. Payments to the Class 1-AF-5 Insurer shall be
made by wire transfer of immediately available funds to the following account,

            (a) If, on the third Business Day before any Distribution Date,
the Trustee determines that the amounts available for such Distribution Date
distributable to the Holders of the Class 1-AF-5 Certificates pursuant to
Section 4.04 will be insufficient to pay the related Required Distributions
due on such Distribution Date, the Trustee shall determine the amount of any
such deficiency and shall give notice to the Class 1-AF-5 Insurer and the
Fiscal Agent, if any, by telephone or telecopy of the amount of such
deficiency, confirmed in writing by notice substantially in the form of
Exhibit A to the Class 1-AF-5 Policy, by 12:00 p.m., New York City time on
such third Business Day. The Trustee's responsibility for delivering the
notice to the Class 1-AF-5 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
of the appropriate court that any scheduled payment of principal or interest
on a Class 1-AF-5 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 1-AF-5 Insurer and the Fiscal Agent, if any, and
(ii) comply with the provisions of the Class 1-AF-5 Policy, to obtain payment
by the Class 1-AF-5 Insurer of such voided scheduled payment. In addition, the
Trustee shall mail notice to all Holders of the Class 1-AF-5 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 1-AF-5 Policy, a copy of which shall be made available to such
Holders by the Trustee. The Trustee shall furnish to the Class 1-AF-5 Insurer
and the Fiscal Agent, if any, its records listing the payments on the affected
Class 1-AF-5 Certificates, if any, that have been made by the Trustee and
subsequently recovered from the affected Holders, and the dates on 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 1-AF-5
Certificates (the "Class 1-AF-5 Policy Payments Account") over which the
Trustee shall have exclusive control and sole right of withdrawal. The Class
1-AF-5 Policy Payments Account shall be an Eligible Account. The Trustee shall
deposit any amount



                                     127
<PAGE>


paid under the Class 1-AF-5 Policy into the Class 1-AF-5 Policy Payments
Account and distribute such amount only for the purposes of making the
payments to Holders of the Class 1-AF-5 Certificates, in respect of the
related Required Distributions for which the related claim was made under the
Class 1-AF-5 Policy. Such amounts shall be allocated by the Trustee to Holders
of Class 1-AF-5 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 1-AF-5
Certificates from funds in the Class 1-AF-5 Policy Payments Account shall be
noted as provided in subsection (e) below. Funds held in the Class 1-AF-5
Policy Payments Account shall not be invested by the Trustee.

            (d) Any funds received from the Class 1-AF-5 Insurer for deposit
into the Class 1-AF-5 Policy Payments Account pursuant to the Class 1-AF-5
Policy in respect of a Distribution Date or otherwise as a result of any claim
under the Class 1-AF-5 Policy shall be applied by the Trustee directly to the
payment in full (i) of the related Required Distributions due on such
Distribution Date on the Class 1-AF-5 Certificates or (ii) of other amounts
payable under the Class 1-AF-5 Policy. Funds received by the Trustee as a
result of any claim under the Class 1-AF-5 Policy shall be used solely for
payment to the Holders of the Class 1-AF-5 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 1-AF-5 Policy Payments Account on
the first Business Day after each Distribution Date shall be remitted promptly
to the Class 1-AF-5 Insurer in accordance with the instructions set forth in
Section 4.04(k).

            (e) The Trustee shall keep complete and accurate records in
respect of (i) all funds remitted to it by the Class 1-AF-5 Insurer and
deposited into the Class 1-AF-5 Policy Payments Account and (ii) the
allocation of such funds to (A) payments of interest on and principal in
respect of any Class 1-AF-5 Certificates (B) Applied Realized Loss Amounts
allocated to the Class 1-AF-5 Certificates and (C) the amount of funds
available to make distributions on the Class 1-AF-5 Certificates pursuant to
Sections 4.04(a), (c), (e) and (f). The Class 1-AF-5 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 1-AF-5
Certificate by its acceptance of the Class 1-AF-5 Certificate agrees, that,
without the need for any further action on the part of the Class 1-AF-5
Insurer or the Trustee, to the extent the Class 1-AF-5 Insurer makes payments,
directly or indirectly, on account of principal of or interest on any Class
1-AF-5 Certificates, the Class 1-AF-5 Insurer will be fully subrogated to the
rights of the Holders of such Class 1-AF-5 Certificates to receive such
principal and interest from the Trust Fund. The Holders of the Class 1-AF-5
Certificates, by acceptance of the Class 1-AF-5 Certificates, assign their
rights as Holders of the Class 1-AF-5 Certificates to the extent of the Class
1-AF-5 Insurer's interest with respect to amounts paid under the Class 1-AF-5
Policy. Anything herein to the contrary notwithstanding, solely for purposes
of determining the Class 1-AF-5 Insurer's rights, as applicable, as subrogee
for payments distributable pursuant to Section 4.04, any payment with respect
to distributions to the Class 1-AF-5 Certificates which is made with funds



                                     128
<PAGE>



received pursuant to the terms of the Class 1-AF-5 Policy shall not be
considered payment of the Class 1-AF-5 Certificates from the Trust Fund and
shall not result in the distribution or the provision for the distribution in
reduction of the Certificate Principal Balance of the Class 1-AF-5
Certificates within the meaning of Article IV.

            (g) Upon its becoming aware of the occurrence of an Event of
Default, the Trustee shall promptly notify the Class 1-AF-5 Insurer of such
Event of Default.

            (h) The Trustee shall promptly notify the Class 1-AF-5 Insurer of
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 1-AF-5 Certificates as to which it
has actual knowledge. Each Holder of a Class 1-AF-5 Certificate, by its
purchase of Class 1-AF-5 Certificates, and the Trustee hereby agrees that the
Class 1-AF-5 Insurer (so long as no Class 1-AF-5 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

occurred and be continuing, each Holder of a Class 1-AF-5 Certificate agrees
that the Class 1-AF-5 Insurer shall be treated by the Depositor, the Master
Servicer and the Trustee as if the Class 1-AF-5 Insurer were the Holder of all
of the Class 1-AF-5 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
1-AF-5 Certificates hereunder.

received under the Corridor Contract may be invested in Permitted Investments
at the written direction of the Majority Holder of the Class C Certificates,
which Permitted Investments shall mature not later than the Business Day
immediately preceding the first Distribution Date that follows the date of
such investment (except that if such Permitted Investment is an obligation of
the institution that maintains the Carryover Reserve Fund, then such Permitted
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 under the Corridor Contract shall be
invested by the Trustee in The Bank of New York cash reserves. Any net

            On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of the Certificateholders, the Credit
Comeback Excess Account. The Credit Comeback Excess Account 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.

            On each Distribution Date, the Trustee shall deposit all Credit
Comeback Excess Amounts in the Credit Comeback Excess Account. The Trustee
shall make withdrawals from the Credit Comeback Excess Account to make

            Funds in the Credit Comeback Excess Account with respect to Loan
Group 1 may be invested in Permitted Investments at the written direction of
the Majority Holder of the Class C Certificates, which Permitted Investments
shall mature not later than the Business Day immediately preceding the first
Distribution Date that follows the date of such investment (except that if
such Permitted Investment is an obligation of the institution that maintains
the Credit Comeback Excess Account, 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 Credit Comeback Excess

of the Class C Certificates in accordance with their Percentage



                                     131

Interests. Any losses incurred in the Credit Comeback Excess Account in
respect of any such investments shall be charged against amounts on deposit in
the Credit Comeback Excess Account (or such investments) immediately as
realized.

            The Trustee shall not be liable for the amount of any loss
incurred in respect of any investment or lack of investment of funds held in
the 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 C Certificates shall evidence ownership of
the Credit Comeback Excess Account for federal tax purposes.

            Section 4.09 Swap Trust and Swap Account.

            On the Closing Date, there is hereby established a separate trust
(the "Swap Trust"), the assets of which shall consist of the Trustee's rights
and obligations under the Swap Contract Administration Agreement. The Swap
Trust shall be maintained by the Swap Trustee, who initially, shall be the
Trustee. The Swap Trustee shall hold the assets of the Swap Trust in trust for
the benefit of the Holders of the Swap Certificates and the Swap Counterparty.
No later than the Closing Date, the Swap Trustee shall establish and maintain
a separate, segregated trust account to be held in the Swap Trust, titled,
"Swap Account, The Bank of New York, as Swap Trustee, in trust for the Swap
Counterparty and the registered holders of CWABS, Inc., Asset-Backed
Certificates, Series 2005-15." Such account 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 of the Trustee held pursuant to this Agreement. Amounts therein shall
be held uninvested. Funds on deposit in the Swap Account shall be distributed
in the amounts and in the order of priority described under Section 4.04(d).
For federal income tax purposes, the Swap Trust, including the Swap Account,
shall be owned by the Class C Certificates.

            On each Distribution Date, the Trustee shall make a deposit to the
Swap Account pursuant to Section 4.04(a)(i), and to the extent that the amount
of such deposit is insufficient to pay any Net Swap Payment and/or Swap
Termination Payment (other than a Swap Termination Payment due to a Swap
Counterparty Trigger Event) due to the Swap Counterparty with respect to such
Distribution Date, the Trustee shall withdraw, out of amounts on deposit in
the Distribution Account in respect of the Principal Remittance Amount for
Loan Group 1 and Loan Group 2, pro rata on the basis of those respective
Principal Remittance Amounts, such additional amount as is necessary to cover
the remaining portion of any such Net Swap Payment and/or Swap Termination
Payment (other than a Swap Termination Payment due to a Swap Counterparty
Trigger Event) due to the Swap Counterparty with respect to such Distribution
Date.

            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 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) in connection with the initial issuance of the
Certificates) 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 (in the case of
the Class P and Class C Certificates only) (the "Investment Letter") or
Exhibit L (in the case of any Private Certificate) (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



                                     134
<PAGE>


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 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 Depositor, the Trust Fund, each Seller, the Master Servicer,
the Class 1-AF-5 Insurer 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) in connection with the initial issuance
of the Certificates) 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 a Plan, 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



                                     135
<PAGE>


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.

            No transfer of a Swap Certificate (other than a transfer of a Swap
Certificate to an affiliate of the Depositor (either directly or through a
nominee) in connection with the initial issuance of the Certificates) shall be
made unless the Trustee shall have received either (i) a representation from
the transferee of such Swap Certificate acceptable to and in form and
substance satisfactory to the Trustee to the effect that such transferee is
not a Plan, or (ii) a representation that the purchase and holding of the Swap
Certificate satisfy the requirements for exemptive relief under PTCE 84-14,
PTCE 90-1, PTCE 91-38, PTCE 95-60, PTCE 96-23 or a similar exemption. In the
event that such a representation letter is not delivered, one of the foregoing
representations, as appropriate, shall be deemed to have been made by the
transferee's (including an initial acquiror's) acceptance of the Swap
Certificate. In the event that such representation is violated, such transfer
or acquisition shall be void and of no effect.

            (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) in
      connection with the initial issuance of the Certificates, no Ownership
      Interest in a Class A-R Certificate may be registered or transferred,
      and the



                                     136
<PAGE>


      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
      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



                                     137
<PAGE>


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 1-AF-5 Holders, the Class 1-AF-5 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
1-AF-5 Insurer and any agent of the Master Servicer, the Trustee, the NIM
Insurer or the Class 1-AF-5 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 1-AF-5 Insurer or any agent of the Master Servicer, the
Trustee, the NIM Insurer or the Class 1-AF-5 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



                                     138
<PAGE>


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;

            (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.



                                     139
<PAGE>


            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 1-AF-5 Insurer of any change in such location
of any such office or agency.

              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



                                     141
<PAGE>


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 1-AF-5 Policy). 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


                                     142
<PAGE>


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 1-AF-5
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 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



                                     143
<PAGE>


                (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 1-AF-5 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, 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 1-AF-5 Policy, in the case of the Class 1-AF-5
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 1-AF-5 Policy, in the case of the Class 1-AF-5 Certificates). 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 and the Class 1-AF-5 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



                                     145
<PAGE>


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
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 1-AF-5 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

            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.



                                     146
<PAGE>


            The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments
furnished to the 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
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;

                (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 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



                                     148
<PAGE>


                (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.

            The Depositor hereby directs the Trustee to execute, deliver and
perform its obligations under the Swap Contract Administration Agreement (in
its capacity as Swap Trustee). The Sellers, the Depositor, the Master Servicer
and the Holders of the Swap Certificates by their acceptance of such
Certificates acknowledge and agree that the Trustee shall execute, deliver and
perform its obligations under the Swap Contract Administration Agreement and
shall do so solely in its capacity as Swap Trustee, as the case may be, and
not in its individual capacity. Every provision of this Agreement relating to
the conduct or affecting the liability of or affording protection to the
Trustee shall apply to the Trustee's execution of the Swap Contract
Administration Agreement in its capacity as Swap Trustee, and the performance
of its duties and satisfaction of its obligations thereunder.

            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



                                     149
<PAGE>


(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
1-AF-5 Policy, in the case of the Class 1-AF-5 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
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, the Class 1-AF-5 Insurer and
each Rating Agency, not less than 60 days before the date specified in such
notice when, subject to Section



                                     150
<PAGE>


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 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.
In addition, if the Swap 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



                                     151
<PAGE>


accepting the appointment as successor Swap Contract Administrator under the
Swap 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
1-AF-5 Policy, in the case of the Class 1-AF-5 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 8.06 and no notice to
Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 8.08.



                                     152
<PAGE>


            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 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



                                     153

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

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 settlement agreements with any
governmental taxing agency, extend any statute of limitations



                                     154
<PAGE>


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 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 and the Swap
Trust, including the Swap Account, as outside reserve funds within the meaning
of Treasury Regulation 1.860G-2(h), neither of which is an asset of any REMIC
created hereunder. The Carryover Reserve Fund shall be treated as owned by the
Class C Certificateholders and the Swap Trust, including the Swap Account
shall be treated as owned by the Class C Certificateholders. The rights of the
Holders of each Class of Certificates (other than the Class P and Class A-R
Certificates) to receive payments from, and the deemed obligations of such
Holders to make payments to, the



                                     155
<PAGE>


Carryover Reserve Fund or the Swap Trust, including the Swap Account, shall be
treated as rights and obligations with respect to notional principal contracts
written by (i) the Corridor Contract Counterparty in respect of any Net Rate
Carryover funded by the Corridor Contract and in respect of any residual
payments from such Corridor Contract received by the Class C Certificates,
(ii) the Holders of the Class C Certificates in respect of any Net Rate
Carryover distributed pursuant to Sections 4.04(c)(iv) and (iii) the Swap
Counterparty in respect of any Net Rate Carryover funded by the Swap Contract
and in respect of any residual payments from such Swap Contract received by
the Class C Certificates. Thus, the Certificates (other than the Class P and
Class A-R Certificates), shall be treated as representing ownership of Master
REMIC regular interests coupled with contractual rights and obligations within
the meaning of Treasury Regulation 1.860G-2(i). In addition, For purposes of
determining the issue price of the various Master REMIC regular interests, the
Trustee shall assume that the (i) the Corridor Contract has a value of $17,000
and (ii) Swap Contract has a value of $1,025,000.

            The Trustee shall treat the entitlement to Credit Comeback Excess
Amounts as owned by the Holders of the Class C 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 C Certificates as payments made by the Holders
of the Class C 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 C Certificate with respect to the R-3-X Interest as
deposited into the Carryover Reserve Fund. In addition, to the extent the
interest otherwise payable to a Certificateholder is reduced for amounts
payable with respect to the Swap Contract, the Trustee, for federal income tax
purposes, shall treat the amount of such reduction as first payable to the
Certificateholder as interest and as then payable by the Certificateholder
with respect to a notional principal contract. To the extent the amount
payable with respect to the Swap Contract exceeds the aggregate of the
reductions described in the immediate sentence, the Trustee, for federal
income tax purposes, shall treat such excess as Realized Losses from Mortgage
Loans and to the extent such Realized Losses (if they had occurred) would be
allocated to a Certificateholder, the Trustee shall treat such amount as first
payable to the Certificateholder as principal and as then payable by the
Certificateholder with respect to a notional principal contract.

            Section 8.12 Access to Records of the Trustee.

            The Trustee shall afford the Sellers, the Depositor, the Master
Servicer, the NIM Insurer, the Class 1-AF-5 Insurer and each Certificate Owner
upon reasonable notice during normal business hours access to all records
maintained by the 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 shall furnish the Depositor, the Master Servicer, the NIM
Insurer, the Class 1-AF-5 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
1-AF-5 Insurer and the Certificate Owner for review and copying any books,
documents, or records requested with respect to the Trustee's respective
duties under this Agreement. The Sellers, the Depositor, the Master Servicer,
the Class 1-AF-5 Insurer and the Certificate Owner shall not have any
responsibility or liability for any action for failure to act by the Trustee
and are not obligated to supervise the performance of the Trustee under this
Agreement or otherwise.

            Section 8.13 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, the Class 1-AF-5 Insurer and the
Certificateholders.

                                 ARTICLE IX.
                                 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

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, (iv) any remaining
unpaid costs and damages incurred by the Trust Fund that arises out of an
actual violation of any predatory or abusive lending law or regulation and (v)
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 claim
under the Class 1-AF-5 Policy, the consent of the Class 1-AF-5 Insurer will
also be required prior to exercising the option specified in clause (a) of the
preceding sentence.

            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



                                     157
<PAGE>


ten percent (10%) or less of the sum of the aggregate 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 1-AF-5 Insurer otherwise
consents, the purchase price for such Mortgage Loans and REO Properties shall
result in a final distribution on the Class 1-AF-5 Certificates and the Class
1-AF-5 Insurer that is sufficient (x) to pay such Class 1-AF-5 Certificates in
full (without the need of any claim under the Class 1-AF-5 Policy) and (y) to
pay any amounts due and payable to the Class 1-AF-5 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.

            The Swap Trust shall terminate on the earlier of (i) the Swap
Contract Termination Date, (ii) the reduction of the aggregate Certificate
Principal Balance of the Swap Certificates to zero and (iii) the termination
of this Agreement.

            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 and the Class 1-AF-5 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 1-AF-5 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 1-AF-5 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



                                     158
<PAGE>


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 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 1-AF-5 Insurer the amounts allocable to such Certificates and the
Class 1-AF-5 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 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 1-AF-5 Insurer, with respect to any
unpaid Class 1-AF-5 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



                                     159
<PAGE>


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.

                                  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, 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



                                     160
<PAGE>


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 1-AF-5
Policy, in the case of the Class 1-AF-5 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 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 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 or interests of the Class 1-AF-5 Insurer in
any of the provisions of this Agreement without its consent, which consent
shall not be unreasonably withheld.

            Notwithstanding any contrary provision of this Agreement, no
amendment shall adversely affect in any material respect the Swap Counterparty
without at least ten Business Days' prior notice to the Swap Counterparty and
without the prior written consent of the Swap Counterparty, which consent
shall not be unreasonably withheld. CHL shall provide the Swap Counterparty

            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 1-AF-5 Insurer, the Swap Counterparty and, if the
amendment required the consent of Certificateholder 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.

            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 and the Swap Counterparty, 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, the NIM
Insurer and the Swap Counterparty 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 and the Swap Counterparty.

            Section 10.05 Notices.

            (a) The Trustee shall use its best efforts to promptly provide
notice to each Rating Agency, the Class 1-AF-5 Insurer and the Swap
Counterparty 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;

                (4) The repurchase or substitution of Mortgage Loans 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:

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 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 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 backed or secured by the Class C or Class P
      Certificates.



                                     166
<PAGE>


            (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).

              TRANSFER AFFIDAVIT FOR THE CLASS A-R CERTIFICATES

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 December 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, 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.

                                    * * *

            "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

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

                       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:

            (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) in
      connection with the initial issuance of the Certificates, 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.

            (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.

            (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.

<PAGE>


            (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.

         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.

Financial Officer or Senior Vice President of the Buyer or, if the Buyer is a

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

         alone, or the Buyer's Family of Investment Companies, owned at least

         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

            more registered investment companies (or series thereof) that have
            the same investment adviser or investment advisers that are

            same parent or because one investment adviser is a majority owned
            subsidiary of the other).

extent expressly modified by an endorsement hereto, the premiums paid in
respect of this Policy are nonrefundable for any reason whatsoever. This
Policy may not be canceled or revoked during the Term of this Policy. An

Guaranteed Distributions insured hereunder shall not include interest, in
respect of principal paid hereunder on an accelerated basis, accruing from

least four Business Days prior to such date of Receipt, Financial Security
shall have Received written notice from the Trustee that such items were to be
delivered on such date and such date was specified in such notice. Such
payment shall be disbursed to the receiver, conservator, debtor-in-possession
or trustee in bankruptcy named in the Order and not to the Trustee or any
Holder directly (unless a Holder has previously paid such amount to the
receiver, conservator, debtor-in-possession or trustee in bankruptcy named in
the Order, in which case such payment shall be disbursed to the Trustee for
distribution to such Holder upon proof of such payment reasonably satisfactory
to Financial Security). In connection with the foregoing, Financial Security
shall have the rights provided pursuant to Section 4.06 of the Pooling and
Servicing Agreement.

         4. Governing Law. This Policy shall be governed by and construed in

Security. The Fiscal Agent is the agent of Financial Security only and the
Fiscal Agent shall in no event be liable to any Holder for any acts of the
Fiscal Agent or any failure of Financial Security to deposit, or cause to be
deposited, sufficient funds to make payments due under this Policy.

         6. Waiver of Defenses. To the fullest extent permitted by applicable
law, Financial Security agrees not to assert, and hereby waives, for the
benefit of each Holder, all rights (whether by counterclaim, setoff or
otherwise) and defenses (including, without limitation, the defense of fraud),
whether acquired by subrogation, assignment or otherwise, to the extent that
such rights and defenses may be available to Financial Security to avoid
payment of its obligations under this Policy in accordance with the express
provisions of this Policy. Nothing in this paragraph shall be construed to
limit or otherwise impair Financial Security's right to pursue recovery or
claims (based on contractual rights, securities law violations, fraud or other
causes of action) against any person or entity, or, except as provided in
paragraph 3 of this Endorsement, to require payment by Financial Security of
any amounts that have been previously paid or that are not otherwise due in
