      POOLING AND SERVICING AGREEMENT, dated as of November 1, 2006, by and
among CWHEQ, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as seller ("CHL" or a
"Seller"), PARK GRANADA LLC, a Delaware corporation, as a seller ("Park
Granada" or a "Seller"), PARK MONACO INC., a Delaware corporation, as a seller
("Park Monaco" or a "Seller"), PARK SIENNA LLC, a Delaware limited liability
company, as a seller ("Park Sienna" or a "Seller", and together with CHL, Park
Granada and Park Monaco, the "Sellers"), COUNTRYWIDE HOME LOANS SERVICING LP,
a Texas limited partnership, as master servicer (the "Master Servicer"), and
THE BANK OF NEW YORK, a New York banking corporation, as trustee (the
"Trustee").

                             PRELIMINARY STATEMENT

      The Depositor is the owner of the Trust Fund that is hereby conveyed to
the Trustee in return for the Certificates. As provided herein, the Trustee
will elect that the Trust Fund (excluding 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 Contract) be treated for
federal income tax purposes as two real estate mortgage investment conduits
(each a "REMIC" or, in the alternative, the "Subsidiary REMIC" and the "Master
REMIC"). The Subsidiary REMIC will hold as assets all property of the Trust,
other than the Carryover Reserve Fund, the Pre-Funding Account and the Trust
Fund's rights with respect to payments received under the Corridor Contract,
and will be evidenced by (i) the Subsidiary REMIC Regular Interests, which
will be uncertificated and will represent the "REMIC regular interests" in the
Subsidiary REMIC, and (ii) the Class S-A-R Interest, which will represent the
"REMIC residual interest" in the Subsidiary REMIC. The Master REMIC will hold
as assets the Subsidiary REMIC Regular Interests and will be evidenced by the
Certificates, each of which (other than the Class A-R Certificate) will
represent ownership of one or more REMIC regular interests in the Master
REMIC. The Class A-R Certificate will represent ownership of the sole Class of
the REMIC residual interest in each REMIC created hereunder. The latest
possible maturity date, for federal income tax purposes, of all REMIC regular
interests created herein shall be the Latest Possible Maturity Date.

                             The Subsidiary REMIC

      The Subsidiary REMIC Regular Interests will have the principal balances,
pass-through rates and corresponding Classes of Certificates as set forth in
the following table:

(1)    The Class SR-A-1 Interest, Class SR-A-2 Interest, Class SR-A-3 Interest,
      Class SR-A-4 Interest, Class SR-A-5 Interest and Class SR-A-6 (the
      "Accretion Directed Classes") will each have a principal balance that is
      equal to 50% of its Corresponding Class of Certificates and on each
      Distribution Date, interest, principal payments and Realized Losses
      shall be allocated so as to cause each of the Accretion Directed Classes
      to continue to equal 50% of its Corresponding Class of Certificates.

(2)    The interest rate with respect to any Distribution Date (and the related
      Interest Accrual Period) for this Subsidiary REMIC Interest is a per
      annum rate equal to the weighted average Adjusted Net Mortgage Rate of
      the Mortgage Loans.

(3)    The SR-Accrual Interest shall have an initial principal balance equal to
      the sum of (a) 50% of the Cut-off Date Principal Balance of the Mortgage
      Loans and (b) 50% of the Overcollateralized Amount. On each Distribution
      Date, interest, principal and Realized Losses shall be allocated so as
      to cause the SR-C Interest to equal the excess of the Stated Principal
      Balance of the Mortgage Loans as of the end of the related Due Period
      (appropriately adjusted for prepayments) over the aggregate Certificate
      Principal Balance of the Accretion Directed Classes (after taking into
      account distributions for such Distribution Date).

(4)    The SR-$100 Interest and the Class SR-P Interest do not pay any
      interest. All Prepayment Charges are allocated to the Class SR-P
      Interest.

(5)    The Class SR-A-R Interest is the sole class of residual interest in the
      Subsidiary REMIC. It has no principal balance and pays no principal or
       interest.

      On each Distribution Date, the Interest Funds, the Principal
Distribution Amount and the Prepayment Charges payable with respect to the
Mortgage Loans will be payable with respect to the Subsidiary REMIC Regular
Interests in the following manner:

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

      (2) Prepayment Charges. All Prepayment Charges are allocated to the
       Class SR-P Interest.

      (3) Principal. Principal shall be allocated among the Subsidiary REMIC
      Interests according to the formulas described above.

                               The Master REMIC

      The following table specifies the class designation, pass through rate,
and principal amount for each class of Master REMIC Interest:

      (1) The Pass-Through Rate for the Class A-1 Certificates for the Accrual
Period for any Distribution Date will be equal to the lesser of (a) One-Month
LIBOR plus the applicable Pass-Through Margin, and (b) the Net Rate Cap.

      (2) The Pass-Through Rates for the Class A-2, Class A-3, Class A-4,
Class A-5 and Class A-6 Certificates for the Accrual Period for any
Distribution Date will be equal to the lesser of (a) the per annum fixed rate
for the Class set forth in the table below and (b) the Net Rate Cap.

        Class of Certificates                                Pass-Through Rate
        ---------------------                                -----------------

        Class A-2....................................               5.571%
        Class A-3....................................               5.712%
        Class A-4....................................               5.731%
        Class A-5....................................               5.945%
        Class A-6....................................               5.693%

      (3) For federal income tax purposes, the Class C Certificates shall have
a Certificate Principal Balance equal to the Overcollateralized Amount.

      (4) For each Accrual Period the Class C Certificates are entitled to an
amount (the "Class C Distributable Amount") equal to the sum of a specified
portion of the interest on the Subsidiary REMIC Regular Interests (other than
the SR-P Interest) equal to the excess of the Net Rate Cap over the product of
two and the weighted average of the rates on the Accretion Directed Classes
(capped at the rates on their Corresponding Class of Certificates) and the
SR-Accrual Interest (subject to a cap of 0.00%). The Pass-Through Rate of the
Class C Certificates shall be a rate sufficient to entitle it to an amount
equal to all interest accrued on the Mortgage Loans less the interest accrued
on the other interests issued by the Master REMIC. The Class C Distributable
Amount for any Distribution Date is payable from current interest on the
Mortgage Loans to the extent not used to increase overcollateralization and
any related amount of overcollateralization released for that Distribution
Date.

      (5) The Class A-R Certificates represent the sole class of residual
interest in each REMIC created hereunder. The Class A-R Certificates are not
entitled to distributions of interest. On the first Distribution Date, the
Class A-R Certificates are entitled to receive $100.00 from the Principal
Reserve Fund.

                                      3

<PAGE>


      (6) For any Distribution Date, the Class P Certificates are entitled to
all Prepayment Charges collected during the related Prepayment Period and the
Master Servicer Prepayment Charge Amount. On the Class P Principal
Distribution Date, the Class P Certificates are entitled to receive $100.00
from the Principal Reserve Fund.

      The foregoing REMIC structure is intended to cause all of the cash from
the Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC
regular interest, without creating any shortfall--actual or potential (other
than for credit losses) to any REMIC regular interest.

      For any purpose for which the interest rate in respect of any Subsidiary
REMIC regular interest created hereunder is calculated, the interest rate on
the Mortgage Loans shall be appropriately adjusted to account for the
difference between the monthly day count convention of the Mortgage Loans and
the monthly day count convention of the regular interests issued by each of

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 and the Certificate Insurer a letter of a
nationally recognized firm of independent public accountants stating whether
or not the Subsequent Mortgage Loans conveyed



                                      46
<PAGE>

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
      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 "The Bank
      of New York, a New York banking corporation, as trustee under the
      Pooling and Servicing Agreement dated as of November 1, 2006, without
      recourse, for Home Equity Loan Asset Backed Certificates, Series
      2006-S7, CWHEQ, Inc.," 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);



                                      47
<PAGE>

            (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 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



                                      48
<PAGE>

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 any
jurisdiction under the laws of which the recordation of the assignment
specified in clause (iii) above is not necessary to protect the Trustee's and
the Certificateholders' interest in the related Mortgage Loan, as evidenced by
an Opinion of Counsel delivered by CHL to the Trustee within 90 days of the
Closing Date (which opinion may be in the form of a "survey" opinion and is
not required to be delivered by counsel admitted to practice law in the
jurisdiction as to which such opinion applies), 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, the Certificate Insurer 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.

      The Trustee or its agent shall maintain possession of the Mortgage Files
in the State of California and shall not remove the Mortgage Files from the
State of California. 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



                                      49
<PAGE>

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 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.

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

      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



                                      50
<PAGE>

other assets included in the Trust Fund, in trust for the exclusive use and
benefit of all present and future Certificateholders.

      The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer, CHL (on behalf of each Seller) and the
Certificate Insurer, 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, CHL (on behalf of each
Seller) and the Certificate Insurer, 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 their face and relate to such Initial Mortgage Loan, and (ii) the
information set forth in items (i), (iv), (v), (vi), (viii) and (ix) 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, CHL (on behalf of each Seller) and the Certificate Insurer 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, CHL (on behalf of each Seller),
the Certificate Insurer and 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



                                      51
<PAGE>

      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 and language indicating that the
      Mortgage Loan is a MOM Loan if the Initial Mortgage Loan is a MOM Loan,
      with evidence of recording indicated thereon, or a copy of the Mortgage
      certified by the public recording office in which Mortgage has been
      recorded;

            (iii) in the case of each Initial Mortgage Loan that is not a MERS
      Mortgage Loan, a duly executed assignment of the Mortgage or a copy
      thereof with recording information, in either case in the form permitted
      by Section 2.01;

            (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.

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



                                      52
<PAGE>

Loan a Replacement Mortgage Loan, which substitution shall be accomplished in
the manner and subject to the conditions set forth in Section 2.03, or (B)
purchase such Initial Mortgage Loan from the Trust Fund within 90 days from
the date CHL was notified of such defect in writing at the Purchase Price of
such Initial Mortgage Loan; provided that any such substitution pursuant to
(A) above or repurchase pursuant to (B) above shall not be effected prior to
the delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof and any substitution pursuant to (A) above shall not be effected prior
to the additional delivery to the Trustee of a Request for File Release. No
substitution will be made in any calendar month after the Determination Date
for such month. The Purchase Price for any such Initial Mortgage Loan shall be
deposited by CHL in the Certificate Account and, upon receipt of such deposit
and Request for File Release with respect thereto, the Trustee shall release
the related Mortgage File to CHL and shall execute and deliver at CHL's
request such instruments of transfer or assignment as CHL has prepared, in
each case without recourse, as shall be necessary to vest in CHL, or a
designee, the Trustee's interest in any Initial Mortgage Loan released
pursuant hereto. If pursuant to the foregoing provisions CHL repurchases an
Initial Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall
cause MERS to execute and deliver an assignment of the Mortgage in recordable
form to transfer the Mortgage from MERS to CHL and shall cause such Mortgage
to be removed from registration on the MERS(R) System in accordance with MERS'
rules and regulations.

      The Trustee shall retain possession and custody of each Mortgage File in
accordance with and subject to the terms and conditions set forth herein. Each
Seller shall promptly deliver to the 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 Mortgage Loan whose
Mortgage File contains any document or documents that does not meet the
requirements of clauses (i)-(iv) and (vi) above and which defect is not
corrected or cured by CHL within 90 days from the date it was notified of such
defect, shall constitute the sole remedy respecting such defect available to
the Trustee, the Depositor and any Certificateholder against any Seller.

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



                                      53
<PAGE>

foregoing documents, such documents appear regular on their face and relate to
such Subsequent Mortgage Loan.

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

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

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

            (i) the original Mortgage Note, endorsed by manual or facsimile
      signature in blank in the following form: "Pay to the order of
      ________________ without recourse", with all intervening endorsements
      that show a complete chain of endorsement from the originator to the
      Person endorsing the Mortgage Note (each such endorsement being
      sufficient to transfer all right, title and interest of the party so
      endorsing, as noteholder or assignee thereof, in and to that Mortgage
      Note), or, if the original Mortgage Note has been lost or destroyed and
      not replaced, an original lost note 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;



                                      54
<PAGE>

            (ii) in the case of each Subsequent 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 Subsequent
      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 Subsequent Mortgage Loan and language indicating that
      the Subsequent Mortgage Loan is a MOM Loan if the Subsequent Mortgage
      Loan is a MOM Loan, with evidence of recording indicated thereon, or a
      copy of the Mortgage certified by the public recording office in which
      Mortgage has been recorded;

            (iii) in the case of each Subsequent Mortgage Loan that is not a
      MERS Mortgage Loan, a duly executed assignment of the Mortgage or a copy
      thereof with recording information, in either case in the form permitted
      by Section 2.01;

            (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.

      If, in the course of such review, the Trustee finds any document or
documents constituting a part of such Mortgage File that do not meet the
requirements of clauses (i)-(iv) and (vi) above, the Trustee shall include
such exceptions in such Final Certification (and the Trustee shall state in
such Final Certification whether any Mortgage File does not then include the
original or duplicate original lender's title policy or a printout of the
electronic equivalent and all riders thereto). If the public recording office
in which a Mortgage or assignment thereof is recorded retains the original of
such Mortgage or assignment, a copy of the original Mortgage or assignment so
retained, with evidence of recording thereon, certified to be true and
complete by such recording office, shall be deemed to satisfy the requirements
of clause (ii), (iii) or (iv) above, as applicable. CHL shall promptly correct
or cure such defect referred to above within 90 days from the date it was so
notified of such defect and, if CHL does not correct or cure such defect
within such period, CHL shall either (A) if the time to cure such defect
expires prior to the end of the second anniversary of the Closing Date,
substitute for the related Subsequent Mortgage Loan a Replacement Mortgage
Loan, which substitution shall be accomplished in the manner and subject to
the conditions set forth in Section 2.03, or (B) purchase such Subsequent
Mortgage Loan from the Trust Fund within 90 days from the date CHL was
notified of such defect in writing at the Purchase Price of such Subsequent
Mortgage Loan; provided that any such substitution pursuant to (A) above or
repurchase pursuant to (B) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05 hereof and
any substitution pursuant to (A) above shall not be effected prior to the
additional delivery to the Trustee of a Request for File Release. No
substitution will be made in any calendar month after



                                      55
<PAGE>

the Determination Date for such month. The Purchase Price for any such
Subsequent Mortgage Loan shall be deposited by CHL in the Certificate Account

Subsequent Mortgage Loan released pursuant hereto. If pursuant to the
foregoing provisions CHL repurchases a Subsequent Mortgage Loan that is a MERS
Mortgage Loan, the Master Servicer shall cause MERS to execute and deliver an

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

      respect to each Initial Mortgage Loan is true and correct in all
      material respects as of the Closing Date.

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

            (9) None of the Mortgage Loans is 30 days or more delinquent.

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

            (11) Each Mortgage Loan is secured by a valid and enforceable
      second lien on the related Mortgaged Property subject only to (1) the
      lien of non-delinquent current real property taxes and assessments, (2)
      covenants, conditions and restrictions, rights of way, easements and
      other matters of public record as of the date of recording of such

                                      59
<PAGE>

      by such Mortgaged Property and identified in the Mortgage File related
       to such Mortgage Loan.

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

      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 second
      priority lien, of the Mortgage subject to the exceptions set forth in
      paragraph (11)



                                      60
<PAGE>

      above; to the best of CHL's knowledge, no claims have been made under
      such mortgage title insurance policy and no prior holder of the related
      Mortgage, including any Seller, has done, by act or omission, anything
      that would impair the coverage of such mortgage title insurance policy.

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

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

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

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

            (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.



                                      61
<PAGE>

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

            (26) [Reserved].

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

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

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

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

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

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

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

            (34) [Reserved];

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



                                      62
<PAGE>

            (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,
      respectively, are secured by investor properties, and no less than
      approximately the percentage specified in the Collateral Schedule of the
      Initial Mortgage Loans 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 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.



                                      63
<PAGE>

            (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
      closed-end second lien 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 closed-end second lien mortgage loans.

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

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



                                      64
<PAGE>

            (48) The Mortgage Rates borne by the Initial Mortgage Loans as of
      the Cut-off Date ranged between the approximate per annum percentages
      specified on the Collateral Schedule and the weighted average Mortgage
      Rate of the Initial Mortgage Loans 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), 2.03(d) and 2.03(e) can be made. No selection was made in a
      manner that would adversely affect the interests of Certificateholders
      or the Certificate Insurer.

            (50) [Reserved].

            (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 Section 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. Section 433
      nor is any Mortgage Loan a "mortgage" as defined in 15 U.S.C. Section
      1602(aa).

            (57) 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.

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

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

            (60) None of the Mortgage Loans that are secured by property
      located in the State of Illinois are in violation of the provisions of
      the Illinois Interest Act; 815 Ill. Comp. Stat. 205/0.01 (2004).

            (61) There is no Mortgage Loan in the Trust Fund that was
      originated on or after March 7, 2003, which is a "high cost home loan"
      as defined under the Georgia Fair Lending Act.

            (62) 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
      5.7, 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.

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

            (64) 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).

            (65) 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.

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

            (67) Each Park Granada Mortgage Loan, Park Monaco Mortgage Loan
      and Park Sienna Mortgage Loan were acquired by Park Granada, Park Monaco
      and Park Sienna, respectively, from CHL. Immediately prior to the
      assignment of each Park Granada Mortgage Loan, Park Monaco Mortgage Loan
      and Park Sienna Mortgage Loan to Park Granada, Park Monaco and Park
      Sienna, respectively, by CHL, CHL had good title to, and was the sole
      owner of, each such Park Granada Mortgage Loan, Park Monaco Mortgage
      Loan and Park Sienna Mortgage Loan free and clear of any pledge, lien,
      encumbrance or security interest.

representation or warranty set forth in Section 2.03(a) through (e) that
materially and adversely affects the interests of the Certificateholders or
the Certificate Insurer in any Mortgage Loan, the party discovering such
breach shall give prompt notice thereof to the other parties, the NIM Insurer
and the Certificate Insurer. Each of the Master Servicer and the Sellers
(each, a "Representing Party") hereby covenants with respect to the
representations and warranties set forth in Sections 2.03(a) through (e) 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 Certificate Insurer, it shall cure such breach in all material
respects and, if such breach is not so cured, shall, (i) if such 90-day period
expires prior to the second anniversary of the Closing Date, remove such
Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and substitute
in its place a Replacement Mortgage Loan, in the manner and subject to the
conditions set forth in this Section; or (ii) repurchase the affected Mortgage
Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner
set forth below; provided that (a) any such substitution pursuant to (i) above
or repurchase pursuant to (ii) above shall not be effected prior to the
delivery to the Trustee of the Opinion of Counsel required by Section 2.05
hereof, (b) any such substitution pursuant to (i) above shall not be effected
prior to the additional delivery to the Trustee of a Request for File



                                      71
<PAGE>

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, the
Certificate Insurer 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.

      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 and the Certificate Insurer the
related Mortgage Note, Mortgage and assignment of the Mortgage, and such other
documents and agreements as are required by Section 2.01, with the Mortgage
Note endorsed and the Mortgage assigned as required by Section 2.01. No
substitution will be made in any calendar month after the Determination Date
for such month. Scheduled Payments due with respect to Replacement Mortgage
Loans in the Due Period related to the Distribution Date on which such
proceeds are to be distributed shall not be part of the Trust Fund and will be
retained by the applicable Seller delivering such Replacement Mortgage Loan on
such Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Scheduled Payment due on any Deleted
Mortgage Loan for the related Due Period and thereafter the applicable Seller
shall be entitled to retain all amounts received in respect of such Deleted
Mortgage Loan. The Master Servicer shall amend the Mortgage Loan Schedule for
the benefit of the Certificateholders to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans
and the Master Servicer shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Replacement Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the
applicable Seller delivering such Replacement Mortgage Loan shall be deemed to
have made with respect to such Replacement Mortgage Loan or Loans, as of the
date of substitution, the representations and warranties set forth in Section
2.03(b), (c), (d) or (e) 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.



                                      72
<PAGE>

      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.

      (g) 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 and the Certificate Insurer with respect to
each Mortgage Loan.

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

                   Substitutions and Repurchases.

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

      (b) Upon discovery by the Depositor, any Seller, the Master Servicer or
the Trustee that any Mortgage Loan does not constitute a "qualified mortgage"
within the meaning of section 860G(a)(3) of the Code, the party discovering
such fact shall promptly (and in any event within five Business Days of
discovery) give written notice thereof to the other parties and the NIM
Insurer. In connection therewith, the Trustee shall require CHL, at CHL's
option, to either (i) substitute, if the conditions in Section 2.03(f) with
respect to substitutions are satisfied, a Replacement Mortgage Loan for the
affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within
