          POOLING AND SERVICING AGREEMENT, dated as of September 1, 2006, by
and among CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as seller ("CHL" 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 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. 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 Contract) for federal income tax purposes will
consist of two REMICs (the"Subsidiary REMIC" and the "Master REMIC"). Each
Certificate, other than the Class A-R Certificate, will represent ownership of
one or more regular interests in the Master REMIC for purposes of the REMIC
Provisions. The Class A-R Certificate represents ownership of the sole class
of residual interest in the Subsidiary REMIC and the Master REMIC. The Master
REMIC will hold as assets the several classes of uncertificated Subsidiary
REMIC Interests (other than the SR-R Interest). Each Subsidiary REMIC Interest
(other than the SR-R Interest) is hereby designated as a regular interest in
the Subsidiary REMIC. The Subsidiary REMIC 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 Contract). The
latest possible maturity date of all REMIC regular interests created in this
Agreement shall be the Latest Possible Maturity Date.

</TABLE>

(1)   The Certificates will accrue interest at the related Pass-Through Rates
     identified in this Agreement.

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

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


                                      3
<PAGE>


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

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

     The foregoing REMIC structure is intended to cause all of the cash from
the Mortgage Loans to flow through to the Master REMIC as cash flow on REMIC
regular interests, without creating any shortfall--actual or potential (other
than for credit losses)-- to any REMIC regular interest. It is not intended
that the Class A-R Certificates be entitled to any cash flows pursuant to this
Agreement except as provided in Section 3.08(a) hereunder.

Fund not otherwise conveyed to the Trustee pursuant to Section 2.01(a) or (b).

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

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

               (1) the Trustee and the Underwriter 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 A-5B
     Policy, in the case of the Class A-5B Certificates);


                                      46

               (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
     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

     Loans will not vary by more than the amount specified below (other than
     (i) 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 (ii) the percentage of Mortgage Loans in the Credit
     Grade Categories of "C" or below, which will not exceed 15% of the
     Mortgage Pool) from the characteristics listed below; provided that for
     the purpose of making such calculations, the characteristics for any
     Initial Mortgage Loan made will be taken as of the Initial Cut-off Date
     and the characteristics for any Subsequent Mortgage Loans will be taken
     as of the Subsequent Cut-off Date:

               (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 Underwriter will be provided with an

                                      47
<PAGE>


     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

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

          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 sufficient to transfer all right, title and
          interest of the party so endorsing, as noteholder or assignee
          thereof, in and to that Mortgage


                                      48
<PAGE>


          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 2006-15, CWABS, Inc., by The Bank
          of New York, a New York banking corporation, as trustee under the
          Pooling and Servicing Agreement dated as of September 1, 2006,
          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 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


                                      49
<PAGE>


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
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


                                       50
<PAGE>


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 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


                                       51
<PAGE>


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, without recourse, all right, title and interest in the
portion of the Trust Fund not otherwise conveyed to the Trustee 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 other assets included in the Trust Fund, in trust for
the exclusive use and benefit of all present and future Certificateholders and
the Class A-5B 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


                                      52
<PAGE>


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), (iii), (iv), (v), (vii), (viii) and (xiv) 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, CHL (on behalf of each Seller),
the Class A-5B 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 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;


                                      53
<PAGE>


               (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 (on its own behalf and
on behalf of Park Monaco and Park Sienna) shall promptly correct or cure such
defect referred to above within 90 days from the date it was so notified of
such defect and, if CHL does not correct or cure such defect within such
period, CHL shall either (A) if the time to cure such defect expires prior to
the end of the second anniversary of the Closing Date, substitute for the
related Initial Mortgage Loan a Replacement Mortgage Loan, which substitution
shall be accomplished in the manner and subject to the conditions set forth in
Section 2.03, or (B) purchase such Initial Mortgage Loan from the Trust Fund
within 90 days from the date CHL was notified of such defect in writing at the
Purchase Price of such Initial Mortgage Loan; provided that any such
substitution pursuant to (A) above or repurchase pursuant to (B) above shall
not be effected prior to the delivery to the Trustee of the Opinion of Counsel
required by Section 2.05 hereof and any substitution pursuant to (A) above
shall not be effected prior to the additional delivery to the 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


                                      54
<PAGE>


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

          The Trustee agrees to execute and deliver within 30 days after the
Subsequent Transfer Date to the Depositor, the Master Servicer and CHL (on
behalf of each Seller) an Interim Certification substantially in the form
annexed hereto as Exhibit G-2 to the effect that, as to each Subsequent
Mortgage Loan listed in the Mortgage Loan Schedule (other than any Subsequent
Mortgage Loan paid in full or any Subsequent Mortgage Loan specifically
identified in such certification as not covered by such certification), all
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), (iii), (iv), (v), (vii), (viii) and (xiv) of the
definition of the "Mortgage Loan Schedule" accurately reflects information set
forth in the Mortgage File. On or before the thirtieth (30th) day after the
Subsequent Transfer Date (or if such thirtieth day is not a Business Day, the
succeeding Business Day), the Trustee shall deliver to the Depositor, the
Master Servicer and CHL (on behalf of each


                                       55
<PAGE>


Seller) a Delay Delivery Certification with respect to the Subsequent Mortgage
Loans substantially in the form annexed hereto as Exhibit G-3, with any
applicable exceptions noted thereon, together with a Subsequent Certification
substantially in the form annexed hereto as Exhibit G-4. The Trustee shall be
under no duty or obligation to inspect, review or examine such documents,
instruments, certificates or other papers to determine that the same are
genuine, enforceable or appropriate for the represented purpose or that they
have actually been recorded in the real estate records or that they are other
than what they purport to be on their face.

          Not later than 180 days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, CHL (on behalf of
each Seller), the Class A-5B 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;

               (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);


                                      56
<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.

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

          The 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 the Sellers to
substitute for or to purchase, pursuant to Section 2.02(b), any Subsequent
Mortgage Loan whose Mortgage File


                                      57
<PAGE>


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.

<PAGE>


               (6) No consent, approval, authorization or order of any court
     or governmental agency or body is required for the execution, delivery
     and performance by CHL of, or compliance by CHL 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, CHL has obtained the same.

               (7) The information set forth on Exhibit F-1 hereto with
     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 Loan-to-Value Ratio at origination
     in excess of 100.00%.

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

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

     below.


                                      61
<PAGE>


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

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

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

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

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

               (21) To the best of CHL's knowledge, no improvement located on
     or being part of the Mortgaged Property is in violation of any applicable
     zoning law or regulation. To the best of CHL's knowledge, all
     inspections, licenses and certificates required to be made or issued with
     respect to all occupied portions of the Mortgaged Property and, with
     respect to the use and occupancy of the same, including but not limited
     to certificates of occupancy and fire underwriting certificates, have
     been made or


                                      62
<PAGE>


     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 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.


                                      63
<PAGE>


               (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.

               (36) On the basis of representations made by the Mortgagors in
     their loan applications, no more than approximately the percentage
     specified in the Collateral Schedule of the Initial Mortgage Loans are
     secured by investor properties, and no less than approximately the
     percentage specified in the Collateral Schedule of the Initial Mortgage
     Loans 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


                                      64
<PAGE>


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

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

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

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

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

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

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

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


                                      65
<PAGE>


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

               (45) The Mortgage Loans originated by CHL were underwritten 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.

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

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

               (49) 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) [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.


                                      66
<PAGE>


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

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

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

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

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

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


                                      67
<PAGE>


     Mortgage pertaining to interest rate adjustments, payment adjustments
     and adjustments of the outstanding principal balance have been made in
     accordance with the terms of the related Mortgage Note and applicable
     law and are enforceable and such adjustments will not affect the
     priority of the Mortgage lien.

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

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

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

               (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.


                                      68
<PAGE>


               (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 originated
     in compliance with all applicable federal, state and local laws.

               (71) 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).

               (72) 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.

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

               (74) Each Mortgage Loan is secured by a "single family
     residence" within the meaning of Section 25(e)(10) of 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.

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

          (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 A-5B Insurer in any Mortgage Loan, the party discovering such breach
shall give prompt notice thereof to the other parties, the NIM Insurer


                                      72
<PAGE>


and the Class A-5B Insurer. Each of the Master Servicer and the Sellers (each,
a "Representing Party") hereby covenants with respect to the representations
and warranties set forth in Sections 2.03(a) through (d) that within 90 days
of the earlier of the discovery by such Representing Party or receipt of
written notice by such Representing Party from any party of a breach of any
representation or warranty set forth herein made that materially and adversely
affects the interests of the Certificateholders in any Mortgage Loan or the
Class A-5B Insurer, it shall cure such breach in all material respects and, if
such breach is not so cured, shall, (i) if such 90-day period expires prior to
the second anniversary of the Closing Date, remove such Mortgage Loan (a
"Deleted Mortgage Loan") from the Trust Fund and substitute in its place a
Replacement Mortgage Loan, in the manner and subject to the conditions set
forth in this Section; or (ii) repurchase the affected Mortgage Loan or
Mortgage Loans from the Trustee at the Purchase Price in the manner set forth
below; provided that (a) any such substitution pursuant to (i) above or
repurchase pursuant to (ii) above shall not be effected prior to the delivery
to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, (b)
any such substitution pursuant to (i) above shall not be effected prior to the
additional delivery to the Trustee of a Request for File Release and (c) any
such substitution pursuant to (i) above shall include a payment by the
applicable Representing Party of any amount as calculated under item (iii) of
the definition of "Purchase Price". Any Representing Party liable for a breach
under this Section 2.03 shall promptly reimburse the Master Servicer or the
Trustee for any expenses reasonably incurred by the Master Servicer or the
Trustee in respect of enforcing the remedies for such breach. To enable the
Master Servicer to amend the Mortgage Loan Schedule, any Representing Party
liable for a breach under this Section 2.03 shall, unless it cures such breach
in a timely fashion pursuant to this Section 2.03, promptly notify the Master
Servicer whether such Representing Party intends either to repurchase, or to
substitute for, the 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 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


                                      73
<PAGE>


the Scheduled Payment due on any Deleted Mortgage Loan for the related Due
Period and thereafter the applicable Seller shall be entitled to retain all
amounts received in respect of such Deleted Mortgage Loan. The Master Servicer
shall amend the Mortgage Loan Schedule for the benefit of the
Certificateholders to reflect the removal of such Deleted Mortgage Loan and
the substitution of the Replacement Mortgage Loan or Loans and the Master
Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon
such substitution, the Replacement Mortgage Loan or Loans shall be subject to
the terms of this Agreement in all respects, and the applicable Seller
delivering such Replacement Mortgage Loan shall be deemed to have made with
respect to such Replacement Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties set forth in Section 2.03(b),
(c) or (d) with respect to such Mortgage Loan. Upon any such substitution and
the deposit to the Certificate Account of the amount required to be deposited
therein in connection with such substitution as described in the following
paragraph, the 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.

          Section 2.04 Representations and Warranties of the Depositor.

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

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

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

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

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


                                      75
<PAGE>


     Agreement or the ability of the Depositor to perform its obligations
     under this Agreement or any Subsequent Transfer Agreement in accordance
     with the terms hereof or thereof.

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

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

          It is understood and agreed that the representations and warranties
set forth in the two immediately preceding paragraphs shall survive delivery
of the Mortgage Files to the Trustee. Upon discovery by the Depositor or the
Trustee, of a breach of any of the foregoing representations and warranties
set forth in the immediately preceding paragraph (referred to herein as a
"breach"), which breach materially and adversely affects the interest of the
Certificateholders, the party discovering such breach shall give prompt
written notice to the others and to each Rating Agency, the NIM Insurer and
the Class A-5B Insurer. The Depositor hereby covenants with respect to the
representations and warranties made by it in this Section 2.04 that within 90
days of the earlier of the discovery 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 A-5B 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 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


                                       76

such repurchase or substitution, as applicable, will not result in the events
described in clause (i) or clause (ii) of the preceding sentence.

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

          Section 2.06 Authentication and Delivery of Certificates.

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

          Section 2.07 Covenants of the Master Servicer.

          The Master Servicer hereby covenants to the Depositor and
