            POOLING AND SERVICING AGREEMENT, dated as of November 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

master servicer (the "Master Servicer"), THE BANK OF NEW YORK, a New York
banking corporation, as trustee (the "Trustee"), and THE BANK OF NEW YORK TRUST
COMPANY, N.A., a national banking association, as co-trustee (the "Co-Trustee").

                              PRELIMINARY STATEMENT

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

            None of the REMICs described herein shall hold any interest in the
Swap Trust, Swap Contract, Swap Account or Final Maturity Reserve Trust.

      SWAP-IO REMIC:

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

(1)  Scheduled principal, prepayments and Realized Losses will be allocated
     first, to the SWR-Support Interest and second, to the numbered classes
     sequentially (from lowest to highest). Amounts so allocated to a numbered
     class shall be further allocated among the "A" and "B" components of such
     numbered class pro-rata until the entire class is reduced to zero.

(2)  Prior to the 61st Distribution Date, a rate equal to twice the Pool Tax Cap
     less 10.40% per annum. On and after the 61st Distribution Date a rate equal
     to the Pool Tax Cap. The "Pool Tax Cap" means the weighted average of the
     Adjusted Net Mortgage Rates of all the Mortgage Loans. For this purpose,
     beginning on the Distribution Date in December 2016 and ending on the Last
     Scheduled Distribution Date, the Adjusted Net Mortgage Rate shall be
     determined by first reducing the interest payable on each 40-Year Mortgage
     Loan by the 40-Year Reserve Rate.

(3)  Prior to the 61st Distribution Date, a rate equal to the lesser of (i)
     10.40% per annum and (ii) twice the Pool Tax Cap. On and after the 61st
     Distribution Date, a rate equal to the Pool Tax Cap.

(4)  On the Closing Date and on each Distribution Date, following the allocation
     of Principal Amounts and Realized Losses, the principal balance in respect
     of the SWR-Support Interest will equal the excess of (a) the sum of (i) the
     principal balance of the Mortgage Loans (as of the end of the related Due
     Period, reduced by principal prepayments received after such Due Period
     that are to be distributed on such Distribution Date) and (ii) the amount,
     if any, on deposit in the Pre-Funding Account in respect of the Mortgage
     Loans over (b) the principal balance in respect of the remaining Swap-IO
     REMIC Interests other than the SWR-P and the SWR-A-R Interests.

(5)  A rate equal to the Pool Tax Cap.

(6)  On each Distribution Date the SWR-P Interest is entitled to all Prepayment
     Charges collected with respect to the Mortgage Loans. It pays no interest.

(7)  Beginning on the Distribution Date in December 2016 and ending on the
     Distribution in November 2036 (the "Last Scheduled Distribution Date"), the
     SW-40 Year Reserve Interest shall be entitled to a specific portion of the
     interest payable on each 40-Year Mortgage Loan. Specifically, the SW-40
     Year Reserve Interest shall be entitled to a specific portion of the
     interest payable on the Stated Principal Balance of each 40-Year Mortgage
     Loan as of the Due Date in the month preceding the month of that
     Distribution Date (after giving effect to principal prepayments in the
     Prepayment Period related to that prior Due Date) at a per annum rate equal
     to 0.80% (the "40-Year Reserve Rate").

(8)  The SW-A-R Interest is the sole class of residual interest in the Swap-IO
     REMIC. It has no principal and pays no principal or interest.

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

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

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

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

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

(2) On each Distribution Date, the pass-through rate for this Strip REMIC
Interest will be the "Strip REMIC Cap," which will equal the weighted average of
the pass-through rates of the Swap-IO REMIC Interests (other than the SWR-P,
SWR-40 Year Reserve and SWR-A-R Interests) treating each "B" Interest the
cardinal number of which (for example, SW-1B, SW-2B, SW-3B, etc.) is not less
than the ordinal number of the Distribution Date (first Distribution Date,
second Distribution Date, third Distribution Date, etc.) as capped at a rate
equal to the product of (i) 2 and (ii) LIBOR.

(3) This Strip REMIC Interest pays no interest.

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

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

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

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

      (1) Interest. Interest is to be distributed with respect to each Strip

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

(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 STR-C-Swap-IO Interest, (b) the interest payable
      on the STR-C-OC Interest (c) the interest payable on the STR-C-40 Year IO
      and (d) a specified portion of the interest payable on the Strip REMIC
      Regular Interests (other than the STR-$100, STR-C-OC, STR-C-Swap-IO,
      STR-C-40 Year IO and STR-P Interests) equal to the excess of the Strip
      REMIC Cap over the weighted average interest rate of the Strip REMIC
      Regular Interests (other than the STR-$100, STR-C-OC, STR-C-Swap-IO,
      STR-C-40 Year IO and STR-P Interests) with each such Class subject to a
      cap equal to the Pass-Through Rate of the Corresponding Master REMIC
      Class. The Pass-Through Rate of the Class C Certificates shall be a rate
      sufficient to entitle it to an amount equal to all interest accrued on the
      Mortgage Loans less the interest accrued on the other interests issued by
      the Master REMIC. The Class C Distributable Amount for any Distribution
      Date is payable from

                                       8
<PAGE>

      current interest on the Mortgage Loans and any related
      Overcollateralization Reduction Amount for that Distribution Date.

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

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

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

interest of such Seller in and to the applicable Initial Mortgage Loans,
including all interest and principal received and receivable by such Seller on
or with respect to applicable Initial Mortgage Loans after the Initial Cut-off
Date (to the extent not applied in computing the Cut-off Date Principal Balance

behalf of such Seller as part of the Initial Certificate Account Deposit as
provided in this Agreement, other than principal due on the applicable Initial
Mortgage Loans on or prior to the Initial Cut-off Date and interest accruing
prior to the Initial Cut-off Date. The Master Servicer confirms that, on behalf
of the Sellers, concurrently with the transfer and assignment, it has deposited

            Immediately upon the conveyance of the Initial Mortgage Loans
referred to in the preceding paragraph, the Depositor sells, transfers, assigns,
sets over and otherwise conveys to

title and interest in and to the Initial Mortgage Loans.

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

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

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

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

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

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

            (1) the Trustee and the Underwriters will be provided Opinions of
      Counsel addressed to the Rating Agencies as with respect to the sale of
      the Subsequent Mortgage Loans conveyed on such Subsequent Transfer Date
      (such opinions being

                                       56
<PAGE>

      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;

            (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 Transfer
      Date was 30 or more days delinquent as of the related Cut-off Date;

            (7) following the conveyance of the Subsequent Mortgage Loans on
      such Subsequent Transfer Date, the characteristics of each Loan Group will
      not vary by more than the amount specified below (other than (i) the
      percentage of Mortgage Loans secured by Mortgaged Properties located in
      the State of California, which will not exceed 50% of the Mortgage Loans
      in each Loan Group and (ii) the percentage of Mortgage Loans in the Credit
      Grade Categories of "C" or below, which will not exceed 15% of the
      Mortgage Loans in each Loan Group) from the characteristics listed below;
      provided that for the purpose of making such calculations, the
      characteristics for any Initial Mortgage Loan made will be taken as of the
      Initial Cut-off Date and the characteristics for any Subsequent Mortgage
      Loans will be taken as of the Subsequent Cut-off Date:

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

            (9) the Trustee and the Underwriters will be provided with an
      Opinion of Counsel, which Opinion of Counsel shall not be at the expense
      of either the Trustee or the Trust Fund, addressed to the Trustee, to the
      effect that such purchase of Subsequent Mortgage Loans will not (i) result
      in the imposition of the tax on "prohibited transactions" on the Trust
      Fund or contributions after the Startup Date, as defined in Sections
      860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any REMIC
      formed hereunder to fail to qualify as a REMIC, such opinion to be
      delivered as provided in Section 2.01(f).

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

            (f) Within six Business Days after each Subsequent Transfer Date,
upon (1) delivery to the Trustee by the Depositor of the Opinions of Counsel
referred to in Section 2.01(e)(1) and (e)(9), (2) delivery to the Trustee by CHL
(on behalf of each Seller) of a Loan Number and Borrower Identification Mortgage
Loan Schedule reflecting the Subsequent Mortgage Loans conveyed on such

Loan was conveyed, (3)deposit in the Certificate Account by the Master Servicer
on behalf of the Sellers of the applicable Subsequent Certificate Account
Deposit, and (4) delivery to the Trustee by the Depositor of an Officer's
Certificate confirming the satisfaction of each of the conditions precedent set
forth in this Section 2.01(f), the Trustee shall pay the applicable Seller the
Subsequent Transfer Date Transfer Amount from such funds that were set aside in
the Pre-Funding Account pursuant to Section 2.01(d). The positive difference, if
any, between the Subsequent Transfer Date Transfer Amount and the Subsequent
Transfer Date Purchase Amount shall be re-invested by the Trustee in the
Pre-Funding Account.

                                       58
<PAGE>

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

            Within thirty days after each Subsequent Transfer Date, the
Depositor shall deliver to the Trustee a letter of a nationally recognized firm
of independent public accountants stating whether or not the Subsequent Mortgage
Loans conveyed on such Subsequent Transfer Date conform to the characteristics
described in Section 2.01(e)(6) and (7).

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

                  (i) the original Mortgage Note, endorsed by manual or
            facsimile signature in blank in the following form: "Pay to the
            order of ________________ without recourse", with all intervening
            endorsements that show a complete chain of endorsement from the
            originator to the Person endorsing the Mortgage Note (each such
            endorsement being sufficient to transfer all right, title and
            interest of the party so endorsing, as noteholder or assignee
            thereof, in and to that Mortgage Note), or, if the original Mortgage
            Note has been lost or destroyed and not replaced, an original lost
            note affidavit, stating that the original Mortgage Note was lost or
            destroyed, together with a copy of the related Mortgage Note 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 2006-21, CWABS, Inc., by The Bank
            of New York, a New York banking corporation, as trustee under the
            Pooling and Servicing Agreement dated as of November 1, 2006,
            without recourse" 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);

                                       59
<PAGE>

                  (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
Certificates issued in connection with such Mortgage Loans. The Sellers further
agree that they will not, and will not permit the Master Servicer to, and the
Master Servicer agrees that it will not, alter the codes referenced in this
paragraph with respect to any Mortgage Loan during the term of this Agreement
unless and until such Mortgage Loan is repurchased in accordance with the terms
of this Agreement.

            In the event that in connection with any Mortgage Loan that is not a
MERS Mortgage Loan a Seller cannot deliver the original recorded Mortgage or all
interim recorded assignments of the Mortgage satisfying the requirements of
clause (ii), (iii) or (iv) concurrently with the execution and delivery hereof,
such Seller shall deliver or cause to be delivered to the Co-Trustee a true copy
of such Mortgage and of each such undelivered interim assignment of the Mortgage
each certified by such Seller, the applicable title company, escrow agent or
attorney, or the originator of such Mortgage, as the case may be, to be a true
and complete copy of the original Mortgage or assignment of Mortgage submitted
for recording. For any such Mortgage Loan that is not a MERS Mortgage Loan each
Seller shall promptly deliver or cause to be delivered to the Co-Trustee such
original Mortgage and such assignment or assignments with 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

                                       60
<PAGE>

Seller shall deliver or cause to be delivered such documents to the Co-Trustee
as promptly as possible upon receipt thereof. If the public recording office in
which a Mortgage or interim assignment thereof is recorded retains the original
of such Mortgage or assignment, a copy of the original Mortgage or assignment so
retained, with evidence of recording thereon, certified to be true and complete
by such recording office, shall satisfy a Seller's obligations in Section 2.01.
If any document submitted for recording pursuant to this Agreement is (x) lost
prior to recording or rejected by the applicable recording office, the
applicable Seller shall immediately prepare or cause to be prepared a substitute
and submit it for recording, and shall deliver copies and originals thereof in
accordance with the foregoing or (y) lost after recording, the applicable Seller
shall deliver to the Co-Trustee a copy of such document certified by the
applicable public recording office to be a true and complete copy of the
original recorded document. Each Seller shall promptly forward or cause to be
forwarded to the Co-Trustee (x) from time to time additional original documents
evidencing an assumption or modification of a Mortgage Loan and (y) any other
documents required to be delivered by the Depositor or the Master Servicer to
the Co-Trustee within the time periods specified in this Section 2.01.

            With respect to each Mortgage Loan other than a MERS Mortgage Loan
as to which the related Mortgaged Property and Mortgage File are located in any
jurisdiction under the laws of which the recordation of the assignment specified
in clause (iii) above is not necessary to protect the Trustee's and the
Certificateholders' interest in the related Mortgage Loan, as evidenced by an
Opinion of Counsel delivered by CHL to the Trustee within 90 days of the Closing
Date (which opinion may be in the form of a "survey" opinion and is not required
to be delivered by counsel admitted to practice law in the jurisdiction as to
which such opinion applies), in lieu of recording the assignment specified in
clause (iii) above, the applicable Seller may deliver an unrecorded assignment
in blank, in form otherwise suitable for recording to the Co-Trustee; provided
that if the related Mortgage has not been returned from the applicable public
recording office, such assignment, or any copy thereof, of the Mortgage may
exclude the information to be provided by the recording office. As to any
Mortgage Loan other than a MERS Mortgage Loan, the procedures of the preceding
sentence shall be applicable only so long as the related Mortgage File is
maintained in the possession of the Co-Trustee in the State or jurisdiction
described in such sentence. In the event that with respect to Mortgage Loans
other than MERS Mortgage Loans (I) any Seller, the Depositor, the Master
Servicer or the NIM Insurer gives written notice to the Trustee that recording
is required to protect the right, title and interest of the Trustee on behalf of
the Certificateholders in and to any Mortgage Loan, (II) a court recharacterizes
any sale of the Mortgage Loans as a financing, or (III) as a result of any
change in or amendment to the laws of the State or jurisdiction described in the
first sentence of this paragraph or any applicable political subdivision
thereof, or any change in official position regarding application or
interpretation of such laws, including a holding by a court of competent
jurisdiction, such recording is so required, the Co-Trustee shall complete the
assignment in the manner specified in clause (iii) 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.

                                       61
<PAGE>

            So long as the Co-Trustee or its agent maintains an office in the
State of California, the Co-Trustee or its agent shall maintain possession of
and not remove or attempt to remove from the State of California any of the
Mortgage Files as to which the related Mortgaged Property is located in such
State. In the event that a Seller fails to record an assignment of a Mortgage
Loan as herein provided within 90 days of notice of an event set forth in clause
(I), (II) or (III) of the 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 Co-Trustee the Mortgage File as required pursuant to this Section
2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase the Delay
Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage Loan for a
Replacement Mortgage Loan, which repurchase or substitution shall be
accomplished in the manner and subject to the conditions set forth in Section
2.03, provided that if CHL fails to deliver a Mortgage File for any Delay
Delivery Mortgage Loan within the period provided in the prior sentence, the
cure period provided for in Section 2.02 or in Section 2.03 shall not apply to
the initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan,
but rather CHL shall have five (5) Business Days to cure such failure to
deliver. CHL shall promptly provide each Rating Agency with written notice of
any cure, repurchase or substitution made pursuant to the proviso of the
preceding sentence. On or before the thirtieth (30th) day (or if such thirtieth
day is not a Business Day, the succeeding Business Day) after the Closing Date
(in the case of Initial Mortgage Loans) or within twenty days after the related
Subsequent Transfer Date (in the case of Subsequent Mortgage Loans), the Trustee
shall, in accordance with the provisions of Section 2.02, send a Delay Delivery
Certification substantially in the form annexed hereto as Exhibit G-3 (with any
applicable exceptions noted thereon) for all Delay Delivery Mortgage Loans
delivered within thirty (30) days after such date. The Trustee will promptly
send a copy of such Delay Delivery Certification to each Rating Agency.

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

            The Trustee agrees to execute and deliver on the Closing Date to the
Depositor, the Master Servicer and CHL (on behalf of each Seller) an Initial
Certification substantially in the form annexed hereto as Exhibit G-1 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification), the documents described in Section 2.01(g)(i) and, in the

                  (iv) the original recorded assignment or assignments of the

            Loan);

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

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

(iii) or (iv) above, as applicable. CHL shall promptly correct or cure such

pursuant hereto. If pursuant to the foregoing provisions CHL repurchases an
Initial Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall
cause MERS to execute and deliver an assignment of the Mortgage in recordable
form to transfer the Mortgage from MERS to CHL and shall cause such Mortgage to

rules and regulations.

herein. Each Seller shall promptly deliver to the Co-Trustee, upon the execution
or receipt thereof, the originals of such other documents or instruments

time to time.

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

            compliance with the doing business laws of any such state, to the
            extent necessary to ensure its ability to enforce each Mortgage
            Loan, to sell the CHL Mortgage Loans in accordance with the terms of
            this Agreement and each Subsequent Transfer Agreement and to perform
            any of its other obligations under this Agreement and each

            and thereof.

            Subsequent Transfer Agreement, assuming the due authorization,
            execution and delivery hereof by the other parties hereto,
            constitutes a legal, valid and binding obligation of CHL,
            enforceable against CHL in accordance with its terms, except that
            (a) the enforceability hereof may be limited by bankruptcy,
            insolvency, moratorium, receivership and other similar laws relating
            to creditors' rights

                                       70

            generally and (b) the remedy of specific performance and injunctive
            and other forms of equitable relief may be subject to equitable
            defenses and to the discretion of the court before which any
            proceeding therefor may be brought.

                  (3) The execution and delivery of this Agreement and each
            Subsequent Transfer Agreement by CHL, the sale of the CHL Mortgage
            Loans by CHL under this Agreement and each Subsequent Transfer
            Agreement, the consummation of any other of the transactions

            Agreement, and the fulfillment of or compliance with the terms
            hereof and thereof are in the ordinary course of business of CHL and
            will not (A) result in a material breach of any term or provision of
            the charter or by-laws of CHL 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 CHL is a party or by which it may
            be bound, or (C) constitute a material violation of any statute,
            order or regulation applicable to CHL of any court, regulatory body,
            administrative agency or governmental body having jurisdiction over
            CHL; and CHL 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 CHL's ability to
            perform or meet any of its obligations under this Agreement and each
            Subsequent Transfer Agreement.

                  (4) CHL is an approved seller of conventional mortgage loans
            for Fannie Mae and Freddie Mac and is a mortgagee approved by the
            Secretary of Housing and Urban Development pursuant to sections 203
            and 211 of the National Housing Act.

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

                  (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.

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

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

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

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

                  (14) There is no valid offset, claim, defense or counterclaim
            to any Mortgage Note or Mortgage, including the obligation of the

            Mortgage Note.

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

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

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

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

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

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

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

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

            and any and all requirements as to completion of any on-site or
            off-site improvements and as to disbursements of any escrow funds
            therefor have been complied with. All costs, fees and expenses
            incurred in making, or closing or recording the Mortgage Loan were
            paid.

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

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

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

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

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

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

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

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

<PAGE>

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

            specified in the Collateral Schedule of the Initial Mortgage Loans
            in Loan Group 1 and Loan Group 2, respectively, are secured by

                  (37) At the Cut-off Date, the improvements upon each Mortgaged
            Property are covered by a valid and existing hazard insurance policy
            with a generally acceptable carrier that provides for fire and
            extended coverage and coverage for such other hazards as are
            customary in the area where the Mortgaged Property is located in an
            amount that is at least equal to the lesser of (i) the maximum
            insurable value of the improvements securing such Mortgage Loan or
            (ii) the greater of (a) the outstanding principal balance of the
            Mortgage Loan and (b) an amount such that the proceeds of such
            policy shall be sufficient to prevent the Mortgagor and/or the
            mortgagee from becoming a co-insurer. If the Mortgaged Property is a
            condominium unit, it is included under the coverage afforded by a
            blanket policy for the condominium unit. All such individual
            insurance policies and all flood policies referred to in item (38)
            below contain a standard mortgagee clause naming the applicable
            Seller or the original mortgagee, and its successors in interest, as
            mortgagee, and the applicable Seller has received no notice that any
            premiums due and payable thereon have not been paid; the Mortgage
            obligates the

                                       75
<PAGE>

            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 the Mortgage
            proceeds, whichever is later, to the day that precedes by one month
            the Due

                                       76
<PAGE>

            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 in
            Loan Group 1 and Loan Group 2 as of the Cut-off Date ranged between
            the approximate per annum percentages specified on the Collateral
            Schedule and the weighted average Mortgage Rate as of the Cut-off
            Date was approximately the per annum rate specified on the
            Collateral Schedule.

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

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

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

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

                                       77
<PAGE>

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

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

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

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

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

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

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

                                       78
<PAGE>

            No borrower obtained a prepaid single-premium credit life,
            disability, accident or health insurance policy in connection with
            the origination of the Mortgage Loan.

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

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

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

                  (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.

                                       79
<PAGE>

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

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

                  (70) Each Prepayment Charge is enforceable and was 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

<PAGE>

                  (xiii) No Mortgage Loan in Loan Group 1 is a balloon mortgage
            loan that has an original stated maturity of less than seven (7)
            years;

                  (xiv) No borrower related to a Mortgage Loan in Loan Group 1
            was encouraged or required to select a Mortgage Loan product offered
            by the Mortgage Loan's originator which is a higher cost product
            designed for less creditworthy borrowers, unless at the time of such
            Mortgage Loan's origination, such borrower did not qualify taking
            into account credit history and debt-to-income ratios for a
            lower-cost credit product then offered by such Mortgage Loan's
            originator or any affiliate of the Mortgage Loan's originator. If,
            at the time of loan application, the borrower may have qualified for
            a lower-cost credit product then offered by any mortgage lending
            affiliate of the Mortgage Loan's originator, the Mortgage Loan's
            originator referred the borrower's application to such affiliate for
            underwriting consideration;

                  (xv) The methodology used in underwriting the extension of
            credit for each Mortgage Loan in Loan Group 1 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 such Mortgage Loan;

                  (xvi) With respect to any Mortgage Loan in Loan Group 1 that
            contains a provision permitting imposition of a premium upon a
            prepayment prior to maturity: (i) prior to the loan's origination,
            the borrower agreed to such premium in exchange for a monetary
            benefit, including but not limited to a rate or fee reduction, (ii)
            prior to the loan's origination, the borrower was offered the option
            of obtaining a mortgage loan that did not require payment of such a
            premium, (iii) the prepayment premium is disclosed to the borrower
            in the loan documents pursuant to applicable state and federal law,
            (iv) for loans originated on or after September 1, 2004, the
            duration of the prepayment period shall not exceed three (3)years
            from the date of the note, unless the loan was modified to reduce
            the prepayment period to no more than three years from the date of
            the note and the borrower was notified in writing of such reduction
            in prepayment period, and (v) notwithstanding any state or federal
            law to the contrary, the Master Servicer shall not impose such
            prepayment premium in any instance when the mortgage debt is
            accelerated as the result of the borrower's default in making the
            loan payments;

                  (xvii) No borrower related to a Mortgage Loan in Loan Group 1
            was required to purchase any credit, life, disability, accident or
            health insurance product as a condition of obtaining the extension
            of credit. No borrower related to a Mortgage Loan in Loan Group 1
            obtained a prepaid single-premium credit, life, disability, accident
            or health insurance policy in connection with the origination of the
            Mortgage Loan in Loan Group 1; No proceeds from any Mortgage Loan in
            Loan Group 1 were used to purchase single premium credit

                                       82
<PAGE>

            insurance policies as part of the origination of, or as a condition
            to closing, such Mortgage Loan;

                  (xviii) All points and fees related to each Mortgage Loan in
            Loan Group 1 were disclosed in writing to the borrower in accordance
            with applicable state and federal law and regulation. Except in the
            case of a Mortgage Loan in Loan Group 1 in an original principal
            amount of less than $60,000 which would have resulted in an
            unprofitable origination, no borrower was charged "points and fees"
            (whether or not financed) in an amount greater than 5% of the
            principal amount of such loan, such 5% limitation is calculated in
            accordance with Fannie Mae's anti-predatory lending requirements as
            set forth in the Fannie Mae Selling Guide;

                  (xix) All fees and charges (including finance charges) and
            whether or not financed, assessed, collected or to be collected in
            connection with the origination and servicing of each Mortgage Loan
            in Loan Group 1 has been disclosed in writing to the borrower in
            accordance with applicable state and federal law and regulation; and

                  (xx) The Master Servicer will transmit full-file credit
            reporting data for each Mortgage Loan pursuant to Fannie Mae Guide
            Announcement 95-19 and that for each Mortgage Loan, Master Servicer
            agrees it shall report one of the following statuses each month as
            follows: new origination, current, delinquent (30-, 60-, 90-days,
            etc.), foreclosed, or charged-off.

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

            and will not (A) result in a material breach of any term or
            provision of the certificate of incorporation or by-laws of Park
            Monaco or (B) materially conflict with, result in a material breach,
            violation or acceleration of, or result in a material default under,

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

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

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

                  (5) No consent, approval, authorization or order of any court
            or governmental agency or body is required for the execution,

<PAGE>

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

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

                  (1) Park Sienna is duly organized as a Delaware limited
            liability company and is validly existing and in good standing under

            may be bound, or (C) constitute a material violation of any statute,

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

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

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

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

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

            (e) Upon discovery by any of the parties hereto of a breach of a
representation or warranty set forth in Section 2.03(a) through (d) that
materially and adversely affects the interests of the Certificateholders in any
Mortgage Loan, the party discovering such breach shall give prompt notice
thereof to the other parties, the NIM Insurer and the Swap Counterparty. Each of
the Master Servicer and the Sellers (each, a "Representing Party") hereby
covenants with respect to the representations and warranties set forth in
Sections 2.03(a) through (d) that within 90 days of the earlier of the discovery
by such Representing Party or receipt of written notice by such Representing
Party from any party of a breach of any representation or warranty set forth
herein made that materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan, 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

                                       86
<PAGE>

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), (b)(76) or (b)(77) shall be deemed to materially and adversely
affect the Certificateholders.

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

                                       87
<PAGE>

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

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

            Section 2.04 Representations and Warranties of the Depositor.

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

                  (1) The Depositor is duly organized and is validly existing as

            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.

                                       88
<PAGE>

                  (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
            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 Co-Trustee. Upon discovery by the Depositor or the
Trustee, of a breach of any of the foregoing representations and warranties set
forth in the immediately preceding paragraph (referred to herein as a "breach"),
which breach materially and adversely affects the interest of the
Certificateholders, the party discovering such breach shall give prompt written
notice to the others and to each Rating Agency, the NIM Insurer and the Swap
Counterparty. The Depositor hereby covenants with respect to the representations
and warranties made by it in this Section 2.04 that within 90 days of the
earlier of the discovery by it or receipt of written notice by it from any party
of a breach of any representation or warranty set forth herein made that
materially and adversely affects the interests of the Certificateholders 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 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 the
Trustee as follows:

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

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

                                 ARTICLE III.
                ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

            Section 3.01      Master Servicer to Service Mortgage Loans.

            For and on behalf of the Certificateholders, the Master Servicer
shall service and administer the Mortgage Loans in accordance with customary and
usual standards of practice of prudent mortgage loan lenders in the respective
states in which the Mortgaged Properties are located, including taking all
required and appropriate actions under each Required Insurance Policy and taking
all required and appropriate actions under each Mortgage Insurance Policy on
behalf of the Co-Trustee, other than the payment of each Mortgage Insurance
Premium and obtaining the approval of each Mortgage Insurer with respect to the
appointment of a successor servicer. In connection with such servicing and
administration, the Master Servicer shall have full power and authority, acting
alone and/or through subservicers as provided in Section 3.02 hereof, subject to
the terms hereof (i) to execute and deliver, on behalf of the Certificateholders
and the Trustee, customary consents or waivers and other instruments and
documents, (ii) to consent to transfers of any Mortgaged Property and
assumptions of the Mortgage Notes and related Mortgages (but only in the manner
provided in this Agreement), (iii) to collect any Insurance Proceeds, other
Liquidation Proceeds and Subsequent Recoveries, and (iv) subject to Section
3.12(b), to effectuate foreclosure or other conversion of the ownership of the
Mortgaged Property securing any Mortgage Loan; provided that the Master Servicer
shall take no action that is inconsistent with or prejudices the interests of
the Trustee or the Certificateholders in any Mortgage Loan or the rights and
interests of the Depositor and the Trustee under this Agreement. The Master
Servicer shall represent and protect the interest of the Trustee in the same
manner as

                                       91
<PAGE>

it currently protects its own interest in mortgage loans in its own portfolio in
any claim, proceeding or litigation regarding a Mortgage Loan and shall not make
or permit any modification, waiver or amendment of any term of any Mortgage Loan
which would (i) cause any REMIC formed hereunder to fail to qualify as a REMIC,
(ii) result in the imposition of any tax under section 860(a) or 860(d) of the
Code or (iii) cause any Covered Mortgage Loan to not be covered by the
applicable Mortgage Insurance Policy, but in any case the Master Servicer shall
not act in any manner that is a lesser standard than that provided in the first
sentence of this Section 3.01. Without limiting the generality of the foregoing,
the Master Servicer, in its own name or in the name of the Depositor and the
Trustee, is hereby authorized and empowered by the Depositor and the Trustee,
when the Master Servicer believes it appropriate in its reasonable judgment, to
execute and deliver, on behalf of the Trustee, the Depositor, the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge and all other
comparable instruments, with respect to the Mortgage Loans, and with respect to
the Mortgaged Properties held for the benefit of the Certificateholders. The
Master Servicer shall prepare and deliver to the Depositor and/or the Trustee
such documents requiring execution and delivery by any or all of them as are
necessary or appropriate to enable the Master Servicer to service and administer
the Mortgage Loans. Upon receipt of such documents, the Depositor and/or the
Trustee shall execute such documents and deliver them to the Master Servicer.
The Master Servicer further is authorized and empowered by the Trustee, on
behalf of the Certificateholders and the Trustee, in its own name or in the name
of the Subservicer, when the Master Servicer or the Subservicer, as the case may
be, believes it appropriate in its best judgment to register any Mortgage Loan
on the MERS(R) System, or cause the removal from the registration of any
Mortgage Loan on the MERS(R) System, to execute and deliver, on behalf of the
Trustee and the Certificateholders or any of them, any and all instruments of
assignment and other comparable instruments with respect to such assignment or
re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns.

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

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

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

                                       92
<PAGE>

respecting defaulted Mortgage Loans. Any amounts collected by the Master
Servicer under any primary insurance policies shall be deposited in the
Certificate Account.

            The Master Servicer shall take whatever action is appropriate to
maximize the amounts payable under each Mortgage Insurance Policy and to service
the Covered Mortgage Loans in the manner required by the applicable Mortgage
Insurance Policy. The Master Servicer shall prepare and submit all claims
eligible for submission under each Mortgage Insurance Policy and shall, except
as otherwise specified in this Agreement, perform all of the obligations of the
insured under each Mortgage Insurance Policy. If either Mortgage Insurance
Policy is terminated for any reason other than the exhaustion of its coverage,
or if the financial strength rating of either Mortgage Insurer is reduced to
below investment grade, the Master Servicer will use its best efforts to obtain
a comparable policy from an insurer that is acceptable to the Rating Agencies.
The replacement policy, if available, shall provide coverage equal to the then
remaining coverage of the applicable Mortgage Insurance Policy. However, if the
premium cost of a replacement policy exceeds the premium cost of that Mortgage
Insurance Policy, the coverage amount of the replacement policy will be reduced
so that its premium cost will not exceed the premium cost of that Mortgage
Insurance Policy.

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

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

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

                                       93
<PAGE>

Subservicing Agreement and the rights and obligations of any Subservicer
pursuant to any Subservicing Agreement in accordance with the terms and
conditions of such Subservicing Agreement. Notwithstanding the provisions of any
subservicing agreement, any of the provisions of this Agreement relating to
agreements or arrangements between the Master Servicer or a subservicer or
reference to actions taken through a Master Servicer or otherwise, the Master
Servicer shall remain obligated and liable to the Depositor, the Trustee and the
Certificateholders for the servicing and administration of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such subservicing agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Master Servicer
alone were servicing and administering the Mortgage Loans. Every subservicing
agreement entered into by the Master Servicer shall contain a provision giving
the successor Master Servicer the option to terminate such agreement without
cost in the event a successor Master Servicer is appointed. All actions of each
subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

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

            Section 3.03 Rights of the Depositor, the Sellers, the
                         Certificateholders, the NIM Insurer and the Trustee in
                         Respect of the Master Servicer.

            None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer or the Depositor shall have any responsibility or liability for any
action or failure to act by the Master Servicer, and none of them is obligated
to supervise the performance of the Master Servicer hereunder or otherwise. The
Master Servicer shall afford (and any Subservicing Agreement shall provide that
each Subservicer shall afford) the Depositor, the NIM Insurer and the Trustee,
upon reasonable notice, during normal business hours, access to all records
maintained by the Master Servicer (and any such Subservicer) in respect of the
Master Servicer's rights and obligations hereunder and access to officers of the
Master Servicer (and those of any such Subservicer) responsible for such
obligations. Upon request, the Master Servicer shall furnish to the Depositor,
the NIM Insurer and the Trustee its (and any such Subservicer's) most recent
financial statements and such other information relating to the Master
Servicer's capacity to perform its obligations under this Agreement that it
possesses. To the extent such information is not otherwise available to the
public, the Depositor, the NIM Insurer and the Trustee shall not disseminate any
information obtained pursuant to the preceding two sentences without the Masters
Servicer's (or any such Subservicer's) written consent, except as required
pursuant to this Agreement or to the extent that it is necessary to do so (i) in
working with legal counsel, auditors, taxing authorities or other governmental
agencies, rating agencies or reinsurers or (ii) pursuant to any law, rule,
regulation, order, judgment, writ, injunction or decree of any court or
governmental authority having jurisdiction over the Depositor, the Trustee, the
NIM Insurer or the Trust Fund, and in either case, the Depositor, the NIM
Insurer or the Trustee, as the case may be, shall use its reasonable best
efforts to assure the confidentiality of any such disseminated non-public
information. The Depositor may, but is not obligated to, enforce the obligations
of

                                       94
<PAGE>

the Master Servicer under this Agreement and may, but is not obligated to,
perform, or cause a designee to perform, any defaulted obligation of the Master
Servicer under this Agreement or exercise the rights of the Master Servicer
under this Agreement; provided by virtue of such performance by the Depositor of
its designee. The Depositor shall not have any responsibility or liability for
any action or failure to act by the Master Servicer and is not obligated to
supervise the performance of the Master Servicer under this Agreement or
otherwise.

            Section 3.04      Trustee to Act as Master Servicer.

            In the event that the Master Servicer shall for any reason no longer
be the Master Servicer hereunder (including by reason of an Event of Default or
termination by the Depositor), the Trustee or its designee shall thereupon
assume all of the rights and obligations of the Master Servicer hereunder
arising thereafter (except that the Trustee shall not be (i) liable for losses
of the Master Servicer pursuant to Section 3.10 hereof or any acts or omissions
of the predecessor Master Servicer hereunder, (ii) obligated to make Advances if
it is prohibited from doing so by applicable law, (iii) obligated to effectuate
repurchases or substitutions of Mortgage Loans hereunder, including pursuant to
Section 2.02 or 2.03 hereof, (iv) responsible for expenses of the Master
Servicer pursuant to Section 2.03 or (v) deemed to have made any representations
and warranties hereunder, including pursuant to Section 2.03 or the first
paragraph of Section 6.02 hereof). If the Master Servicer shall for any reason
no longer be the Master Servicer (including by reason of any Event of Default or
termination by the Depositor), the Trustee (or any other successor servicer)
may, at its option, succeed to any rights and obligations of the Master Servicer
under any subservicing agreement in accordance with the terms thereof; provided
that the Trustee (or any other successor servicer) shall not incur any liability
or have any obligations in its capacity as servicer under a subservicing
agreement arising prior to the date of such succession unless it expressly
elects to succeed to the rights and obligations of the Master Servicer
thereunder; and the Master Servicer shall not thereby be relieved of any
liability or obligations under the subservicing agreement arising prior to the
date of such succession.

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

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

            (a) The Master Servicer shall make reasonable efforts in accordance
with customary and usual standards of practice of prudent mortgage lenders in
the respective states in which the Mortgaged Properties are located to collect
all payments called for under the terms and provisions of the Mortgage Loans to
the extent such procedures shall be consistent with this Agreement and the terms
and provisions of any related Required Insurance Policy. Consistent with the
foregoing, the Master Servicer may in its discretion (i) waive any late payment
charge or, subject to Section 3.20, any Prepayment Charge or penalty interest in
connection with the prepayment of a Mortgage Loan and (ii) extend the due dates
for payments due on a Mortgage

                                       95
<PAGE>

Note for a period not greater than 270 days. In the event of any such
arrangement, the Master Servicer shall make Advances on the related Mortgage
Loan during the scheduled period in accordance with the amortization schedule of
such Mortgage Loan without modification thereof by reason of such arrangements.
In addition, the NIM Insurer's prior written consent shall be required for any
waiver of Prepayment Charges or for the extension of the due dates for payments
due on a Mortgage Note, if the aggregate number of outstanding Mortgage Loans
that have been granted such waivers or extensions exceeds 5% of the aggregate
number of Initial Mortgage Loans and Subsequent Mortgage Loans. The Master
Servicer shall not be required to institute or join in litigation with respect
to collection of any payment (whether under a Mortgage, Mortgage Note or
otherwise or against any public or governmental authority with respect to a
taking or condemnation) if it reasonably believes that enforcing the provision
of the Mortgage or other instrument pursuant to which such payment is required
is prohibited by applicable law.

            (b) The Master Servicer shall establish and maintain a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited on
a daily basis within two Business Days of receipt, except as otherwise
specifically provided herein, the following payments and collections remitted by
Subservicers or received by it in respect of Mortgage Loans subsequent to the
Cut-off Date (other than in respect of principal and interest due on the
Mortgage Loans on or before the Cut-off Date) and the following amounts required
to be deposited hereunder:

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

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

                  (3) all Insurance Proceeds;

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

                  (5) all Compensating Interest;

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

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

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

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

                                       96
<PAGE>

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

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

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

            No later than 1:00 p.m. Pacific time on the Master Servicer Advance
Date in each of December 2006, January 2007 and February 2007, CHL shall remit
to the Master Servicer, and the Master Servicer shall deposit in the Certificate
Account, the Seller Shortfall Interest Requirement (if any) for such Master
Servicer Advance Date.

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

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

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

            The foregoing requirements for remittance by the Master Servicer and
deposit by the Trustee into the Distribution Account shall be exclusive. In the
event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time direct the Trustee to withdraw such amount from the
Distribution Account, any provision herein to the contrary notwithstanding. Such
direction may be accomplished by delivering a written notice to the Trustee that
describes the amounts deposited in error in the Distribution Account. All funds
deposited in the Distribution Account shall be held by the Trustee in trust for
the Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.08. In no event shall the Trustee incur
liability for withdrawals from the Distribution Account at the direction of the
Master Servicer.

            (d) If the Pre-Funded Amount is greater than zero, the Trustee shall
establish and maintain, on behalf of the Certificateholders, the Pre-Funding
Account, and on the Closing

Pre-Funding Account.

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

            (e) Each institution that maintains the Certificate Account, the
Distribution Account or the Pre-Funding Account shall invest the funds in each
such account, as directed by the Master Servicer, in Permitted Investments,
which shall mature not later than (x) in the case of the Certificate Account,
the second Business Day next preceding the related Distribution Account Deposit
Date (except that if such Permitted Investment is an obligation of the
institution that maintains such Certificate Account, then such Permitted
Investment shall mature not later than the Business Day next preceding such
Distribution Account Deposit Date) and (y) in the case of the Distribution
Account and the Pre-Funding Account, the Business Day immediately preceding the
first Distribution Date that follows the date of such investment (except that if
such Permitted Investment is an obligation of the institution that maintains
such Distribution Account or Pre-Funding Account, then such Permitted Investment
shall mature not later than such Distribution Date), in each case, shall not be
sold or disposed of prior to its maturity. All such Permitted Investments shall
be made in the name of the Trustee, for the benefit of the Certificateholders.
In the case of (i) the Certificate Account and the Distribution Account, all
income and gain net of any losses realized from any such investment shall be for
the benefit of the Master Servicer as servicing compensation and shall be
remitted to it monthly as provided herein and (ii) the Pre-Funding Account, all
income and gain net of any losses realized from any such investment shall be for
the benefit of the Depositor and shall be remitted to the Depositor as provided
herein. The amount of any losses incurred in the Certificate Account or the
Distribution Account in respect of any such investments shall be deposited by
the Master Servicer in the Certificate Account or paid to the Trustee for
deposit into the Distribution Account out of the Master Servicer's own funds
immediately as realized. The amount of any losses incurred in the Pre-Funding
Account in respect of any such investments shall be paid by the Master Servicer
to the Trustee for deposit into the Pre-Funding Account out of the Master
Servicer's own funds immediately as realized. The Trustee shall not be liable
for the amount of any loss incurred in respect of any investment or lack of
investment of funds held in the Certificate Account, the Distribution Account or
the Pre-Funding Account and made in accordance with this Section 3.05.

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

            (g) Except as otherwise expressly provided in this Agreement, if any
default occurs under any Permitted Investment, the Trustee may and, subject to
Sections 8.01 and

                                       98

50% of the Voting Rights or the NIM Insurer, shall take any action appropriate
to enforce payment or performance, including the institution and prosecution of
appropriate proceedings.

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

            To the extent required by the related Mortgage Note, the Master
Servicer shall establish and maintain one or more accounts (each, an "Escrow
Account") and deposit and retain therein all collections from the Mortgagors (or
advances by the Master Servicer) for the payment of taxes, assessments, hazard
insurance premiums or comparable items for the account of the Mortgagors.
Nothing herein shall require the Master Servicer to compel a Mortgagor to
establish an Escrow Account in violation of applicable law.

            Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Master Servicer out of related collections for any payments made pursuant to
Sections 3.01 hereof (with respect to taxes and assessments and insurance
premiums) and 3.10 hereof (with respect to hazard insurance), to refund to any
Mortgagors any sums as may be determined to be overages, to pay interest, if
required by law or the terms of the related Mortgage or Mortgage Note, to
Mortgagors on balances in the Escrow Account or to clear and terminate the
Escrow Account at the termination of this Agreement in accordance with Section
9.01 hereof. The Escrow Accounts shall not be a part of the Trust Fund.

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

            The Master Servicer shall afford the Depositor, the NIM Insurer and
the Trustee reasonable access to all records and documentation regarding the
Mortgage Loans and all accounts, insurance policies and other matters relating
to this Agreement, such access being afforded without charge, but only upon
reasonable request and during normal business hours at the offices of the Master
Servicer designated by it. Upon request, the Master Servicer shall furnish to
the Trustee and the NIM Insurer its most recent publicly available financial
statements and any other information relating to its capacity to perform its
obligations under this Agreement reasonably requested by the NIM Insurer.

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

the Certificate Account for the following purposes:

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

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

                  (iii) [Reserved];

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

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

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

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

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

                                      100

            withdrawal from the Certificate Account for deposit into the
            Distribution Account pursuant to the following paragraph;

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

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

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

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

            The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee. On the
Closing Date, CHL shall deposit into the Principal Reserve Fund $200.00. Funds
on deposit in the Principal Reserve Fund shall not be invested. The Principal
Reserve Fund shall be treated as an "outside reserve fund" under applicable
Treasury regulations and shall not be part of any REMIC created under this
Agreement.

            On the Business Day before the first Distribution Date, the Trustee
shall transfer $100.00 from the Principal Reserve Fund to the Distribution
Account, and on the first Distribution Date, the Trustee shall withdraw $100 and

Principal Reserve Fund.

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

            (b) The Trustee shall withdraw funds from the Distribution Account
for distribution to the Certificateholders and remittance to the Final Maturity

of Section 8.11). In addition, the Trustee may from time to time make

            compensation, earnings on or investment income with respect to funds
            in or credited to the Distribution Account;

                  (iii) to withdraw pursuant to Section 3.05 any amount

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

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

                  (vi) to pay to the Co-Trustee, for payment to each Mortgage

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

                  (2) to clear and terminate the Carryover Reserve Fund upon

            Section 3.09      [Reserved].

            Section 3.10      Maintenance of Hazard Insurance.

            The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the lesser of (i) the maximum insurable value of the improvements
securing such Mortgage Loan and (ii) the greater of (a) the outstanding
principal balance of the Mortgage Loan and (b) an amount such that the proceeds
of such policy shall be sufficient to prevent the related Mortgagor and/or
mortgagee from becoming a co-insurer. Each such policy of standard hazard
insurance shall contain, or have an accompanying endorsement that contains, a
standard mortgagee clause. The Master Servicer shall also cause flood insurance
to be maintained on property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan, to the extent described below. Pursuant to
Section 3.05 hereof, any amounts collected by the Master Servicer under any such
policies (other than the amounts to be applied to the restoration or repair of
the related Mortgaged Property or property thus acquired or amounts released to
the Mortgagor in accordance with the Master Servicer's normal servicing
procedures) shall be deposited in the Certificate Account. Any cost incurred by
the Master Servicer in maintaining any such insurance shall not, for the purpose
of calculating monthly distributions to the Certificateholders or remittances to
the Trustee for their benefit, be added to the principal balance of the Mortgage
Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs
shall be recoverable by the Master Servicer out of late payments by the related
Mortgagor or out of Liquidation Proceeds or Subsequent Recoveries to the extent
permitted by Section 3.08 hereof. It is understood and agreed that no earthquake
or other additional insurance is to be required of any Mortgagor or maintained
on property acquired in respect of a Mortgage other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property is located at the
time of origination of the Mortgage Loan in a federally designated special flood
hazard area and such area is participating in the national flood insurance
program, the Master Servicer shall cause flood insurance to be maintained with
respect to such Mortgage Loan. Such flood insurance shall be in an amount equal
to the lesser of (i) the original principal balance of the related Mortgage
Loan, (ii) the replacement value of the improvements that are part of such
Mortgaged Property, or (iii) the maximum amount of such insurance available for
the related Mortgaged Property under the Flood Disaster Protection Act of 1973,
as amended. If the hazard policy contains a deductible clause, the Master
Servicer will be required to deposit from its own funds into the Certificate
Account the amounts that would have been deposited therein but for the
deductible clause.

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

            (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect

                                      103
<PAGE>

or jeopardize coverage under any Required Insurance Policy. Notwithstanding the
foregoing, the Master Servicer is not required to exercise such rights with
respect to a Mortgage Loan if the Person to whom the related Mortgaged Property
has been conveyed or is proposed to be conveyed satisfies the terms and
conditions contained in the Mortgage Note and Mortgage related thereto and the
consent of the mortgagee under such Mortgage Note or Mortgage is not otherwise
so required under such Mortgage Note or Mortgage as a condition to such
transfer. In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Master Servicer is authorized, subject to Section
3.11(b), to take or enter into an assumption and modification agreement from or
with the person to whom such property has been or is about to be conveyed,
pursuant to which such person becomes liable under the Mortgage Note and, unless
prohibited by applicable state law, the Mortgagor remains liable thereon,
provided that the Mortgage Loan shall continue to be covered (if so covered
before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies. The Master Servicer, subject to Section 3.11(b), is also
authorized with the prior approval of the insurers under any Required Insurance
Policies to enter into a substitution of liability agreement with such Person,
pursuant to which the original Mortgagor is released from liability and such
Person is substituted as Mortgagor and becomes liable under the Mortgage Note.
The Master Servicer shall notify the Trustee that any such substitution,
modification or assumption agreement has been completed by forwarding to the
Co-Trustee the executed original of such substitution or assumption agreement,
which document shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof.

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

                                      104
<PAGE>

thereof. Any fee collected by the Master Servicer for entering into an
assumption or substitution of liability agreement will be retained by the Master
Servicer as additional servicing compensation.

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

            (a) The Master Servicer may agree to a modification of any Mortgage
Loan (the "Modified Mortgage Loan") if (i) CHL purchases the Modified Mortgage
Loan from the Trust Fund immediately following the modification as described
below and (ii) the Stated Principal Balance of such Mortgage Loan, when taken
together with the aggregate of the Stated Principal Balances of all other
Mortgage Loans in the same Loan Group that have been so modified since the
Closing Date at the time of those modifications, does not exceed an amount equal
to 5% of the aggregate Certificate Principal Balance of the Certificates.
Effective immediately after the modification, and, in any event, on the same
Business Day on which the modification occurs, all interest of the Trustee in
the Modified Mortgage Loan shall automatically be deemed transferred and
assigned to CHL and all benefits and burdens of ownership thereof, including the
right to accrued interest thereon from the date of modification and the risk of
default thereon, shall pass to CHL. The Master Servicer shall promptly deliver
to the Trustee a certification of a Servicing Officer to the effect that all
requirements of this paragraph have been satisfied with respect to the Modified
Mortgage Loan. For federal income tax purposes, the Trustee shall account for
such purchase as a prepayment in full of the Modified Mortgage Loan. CHL shall
remit the Purchase Price to the Master Servicer for deposit into the Certificate
Account pursuant to Section 3.05 within one Business Day after the purchase of
the Modified Mortgage Loan. Upon receipt by the Trustee of written notification
of any such deposit signed by a Servicing Officer, the Trustee shall release to
CHL or its designee the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as shall
be necessary to vest in CHL any Modified Mortgage Loan previously transferred
and assigned pursuant hereto. CHL covenants and agrees to indemnify the Trust
Fund against any liability for any "prohibited transaction" taxes and any
related interest, additions, and penalties imposed on the Trust Fund established
hereunder as a result of any modification of a Mortgage Loan effected pursuant
to this subsection (a), any holding of a Modified Mortgage Loan by the Trust
Fund or any purchase of a Modified Mortgage Loan by CHL (but such obligation
shall not prevent CHL or any other appropriate Person from in good faith
contesting any such tax in appropriate proceedings and shall not prevent CHL
from withholding payment of such tax, if permitted by law, pending the outcome
of such proceedings). CHL shall have no right of reimbursement for any amount
paid pursuant to the foregoing indemnification, except to the extent that the
amount of any tax, interest, and penalties, together with interest thereon, is
refunded to the Trust Fund or CHL. If the Master Servicer agrees to a
modification of any Mortgage Loan pursuant to this Section 3.12(a), and if such
Mortgage Loan carries a Prepayment Charge provision, CHL shall deliver to the
Trustee the amount of the Prepayment Charge, if any, that would have been due
had such Mortgage Loan been prepaid at the time of such modification, for
deposit into the Certificate Account (not later than 1:00 p.m. Pacific time on
the Master Servicer Advance Date immediately succeeding the date of such
modification) for distribution in accordance with the terms of this Agreement.

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

            With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such REO
Property solely as the Trustee hereunder and not in its individual capacity. The
Master Servicer shall ensure that the title to such REO Property references this
Agreement and the Trustee's capacity thereunder. Pursuant to its efforts to sell
such REO Property, the Master Servicer shall either itself or through an agent
selected by the Master Servicer protect and conserve such REO Property in the
same manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Master Servicer deems to be in the best interest of the Master Servicer and the
Certificateholders for the period prior to the sale of such REO Property. The
Master Servicer shall prepare for and deliver to the Trustee a statement with
respect to each REO Property that has been rented showing the aggregate rental
income received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Certificate Account no later than the close of business on each
Determination Date. The Master Servicer shall perform the tax reporting and
withholding related to foreclosures, abandonments and cancellation of
indebtedness income as specified by Sections 1445, 6050J and 6050P of the Code
by preparing and filing such tax and information returns, as may be required.

            In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that

                                      106
<PAGE>

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

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

            The Liquidation Proceeds from any liquidation of a Mortgage Loan and
any Subsequent Recoveries, net of any payment to the Master Servicer as provided
above, shall be deposited in the Certificate Account as provided in Section 3.05
for distribution on the related Distribution Date, except that any Excess
Proceeds shall be retained by the Master Servicer as additional servicing
compensation.

            The proceeds of any Liquidated Mortgage Loan, as well as any
recovery resulting from a partial collection of Liquidation Proceeds or any
income from an REO Property, will be applied in the following order of priority:
first, to reimburse the Master Servicer for any related unreimbursed Servicing
Advances and Servicing Fees, pursuant to Section 3.08(a)(vi) or this Section
3.12; second, to reimburse the Master Servicer for any unreimbursed Advances,
pursuant

                                      107
<PAGE>

to Section 3.08(a)(ii) or this Section 3.12; third, to accrued and unpaid
interest (to the extent no Advance has been made for such amount) on the
Mortgage Loan or related REO Property, at the Net Mortgage Rate to the Due Date
occurring in the month in which such amounts are required to be distributed; and
fourth, as a recovery of principal of the Mortgage Loan.

            (c) [Reserved].

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

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

            Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, the Master Servicer will promptly notify the
Co-Trustee by delivering a Request for File Release. Upon receipt of such
request, the Co-Trustee shall promptly release the related Mortgage File to the
Master Servicer, and the Co-Trustee shall at the Master Servicer's direction
execute and deliver to the Master Servicer the request for reconveyance, deed of
reconveyance or release or satisfaction of mortgage or such instrument releasing
the lien of the Mortgage in each case provided by the Master Servicer, together
with the Mortgage Note with written evidence of cancellation thereon. The Master
Servicer is authorized to cause the removal from the registration on the MERS(R)
System of such Mortgage and to execute and deliver, on behalf of the Trust Fund
and the Certificateholders or any of them, any and all instruments of
satisfaction or cancellation or of partial or full release. No expenses incurred
in connection with any instrument of satisfaction or deed of reconveyance shall
be chargeable to the Certificate Account, the Distribution Account, the
Carryover Reserve Fund or the related subservicing account. From time to time
and as shall be appropriate for the servicing or foreclosure of any Mortgage
Loan,

                                      108
<PAGE>

including for such purpose, collection under any policy of flood insurance any
fidelity bond or errors or omissions policy, or for the purposes of effecting a
partial release of any Mortgaged Property from the lien of the Mortgage or the
making of any corrections to the Mortgage Note or the Mortgage or any of the
other documents included in the Mortgage File, the Co-Trustee shall, upon
delivery to the Co-Trustee of a Request for Document Release or a Request for
File Release, as applicable, release the documents specified in such request or
the Mortgage File, as the case may be, to the Master Servicer. Subject to the
further limitations set forth below, the Master Servicer shall cause the
Mortgage File or documents so released to be returned to the Co-Trustee when the
need therefor by the Master Servicer no longer exists, unless the Mortgage Loan
is liquidated and the proceeds thereof are deposited in the Certificate Account,
in which case the Master Servicer shall deliver to the Co-Trustee a Request for
File Release for any remaining documents in the Mortgage File not in the
possession of the Master Servicer.

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

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

            Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Co-Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise are
collected by the Master Servicer as Liquidation Proceeds, Insurance Proceeds or
Subsequent Recoveries in respect of any Mortgage Loan. All Mortgage Files and
funds collected or held by, or under the control of, the Master Servicer in
respect of any Mortgage Loans, whether from the collection of principal and
interest payments or from Liquidation Proceeds or Subsequent Recoveries
including but not limited to, any funds on deposit in the Certificate Account,
shall be held by the Master Servicer for and on behalf of the Trust Fund and
shall be and remain the sole and exclusive property of the Trust Fund, subject
to the applicable

                                      109
<PAGE>

provisions of this Agreement. The Master Servicer also agrees that it shall not
create, incur or subject any Mortgage File or any funds that are deposited in
the Certificate Account, the Distribution Account, the Carryover Reserve Fund or
in any Escrow Account (as defined in Section 3.06), or any funds that otherwise
are or may become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy, writ
of attachment or other encumbrance, or assert by legal action or otherwise any
claim or right of set off against any Mortgage File or any funds collected on,
or in connection with, a Mortgage Loan, except, however, that the Master
Servicer shall be entitled to set off against and deduct from any such funds any
amounts that are properly due and payable to the Master Servicer under this
Agreement.

            Section 3.15      Servicing Compensation.

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

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

            Section 3.16      Access to Certain Documentation.

            The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising Holders of the Certificates and
Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC
and such other authorities, access to the documentation regarding the Mortgage
Loans required by applicable regulations of the OTS and the FDIC. Such access
shall be afforded without charge, but only upon reasonable and prior written
request and during normal business hours at the offices of the Master Servicer
designated by it. Nothing in this Section shall limit the obligation of the
Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer to
provide access as provided in this Section as a result of such obligation shall
not constitute a breach of this Section.

            Section 3.17      Annual Statement as to Compliance.

            (a) The Master Servicer shall deliver to the Depositor and the
Trustee on or before March 15 of each year, commencing with its 2007 fiscal
year, an Officer's Certificate stating, as to the signer thereof, that (i) a
review of the activities of the Master Servicer during

                                      110
<PAGE>

the preceding calendar year (or applicable portion thereof) and of the
performance of the Master Servicer under this Agreement, has been made under
such officer's supervision and (ii) to the best of such officer's knowledge,
based on such review, the Master Servicer has fulfilled all its obligations
under this Agreement, in all material respects throughout such year (or
applicable portion thereof), or, if there has been a failure to fulfill any such
obligation in any material respect, specifying each such failure known to such
officer and the nature and status thereof and (iii) to the best of such
officer's knowledge, each Subservicer has fulfilled all its obligations under
its Subservicing Agreement in all material respects throughout such year, or, if
there has been a failure to fulfill any such obligation in any material respect
specifying each such failure known to such officer and the nature and status
thereof.

            (b) The Master Servicer shall cause each Subservicer to deliver to
the Depositor and the Trustee on or before March 15 of each year, commencing
with its 2007 fiscal year, an Officer's Certificate stating, as to the signer
thereof, that (i) a review of the activities of such Subservicer during the
preceding calendar year (or applicable portion thereof) and of the performance
of the Subservicer under the applicable Subservicing Agreement or primary
servicing agreement, has been made under such officer's supervision and (ii) to
the best of such officer's knowledge, based on such review, such Subservicer has
fulfilled all its obligations under the applicable Subservicing Agreement or
primary servicing agreement, in all material respects throughout such year (or
applicable portion thereof), or, if there has been a failure to fulfill any such
obligation in any material respect, specifying each such failure known to such
officer and the nature and status thereof.

            (c) The Trustee shall forward a copy of each such statement to each
Rating Agency. Copies of such statement shall be provided by the Trustee to any
Certificateholder or Certificate Owner upon request at the Master Servicer's
expense, provided such statement is delivered by the Master Servicer to the
Trustee.

            Section 3.18      [Reserved].

            Section 3.19      [Reserved].

            Section 3.20      Prepayment Charges.

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

                                      111
<PAGE>

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

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

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

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

            Section 3.21      Swap Contract.

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

                                      112
<PAGE>

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

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

            Upon the Swap Contract Administrator obtaining actual knowledge of
a Moody's First Level Downgrade or a S&P First Level Downgrade with respect to
the Swap Counterparty (each as defined in the Swap Contract) or upon the Swap
Contract Administrator obtaining actual knowledge of a Moody's Second Level
Downgrade or a S&P Second Level Downgrade with respect to the Swap
Counterparty (each as defined in the Swap Contract), the Swap Trustee shall
direct the Swap Contract Administrator to (i) demand payment of the Delivery
Amount (as defined in the Swap Contract) from the Swap Counterparty on each
Valuation Date (as defined in the Swap Contract) and to perform its other
obligations in accordance with the Swap Contract and (ii) take such other
action required under the Swap Contract. If a Delivery Amount is demanded, the
Swap Contract Administrator, in accordance with the Swap Contract
Administration Agreement, shall establish an account to hold cash and other
eligible investments pledged under the Swap Contract. Any cash or other
Eligible Collateral pledged under the Swap Contract shall not be part of the
Distribution Account or the Swap Account unless remitted to such accounts by
the Swap Contract Administrator in accordance with the Swap Contract
Administration Agreement. If Eligible Collateral with a value equal to the
Delivery Amount is not delivered to the Swap Contract Administrator by the
Swap Counterparty, the Swap Trustee shall direct the Swap Contract
Administrator to notify the Swap Counterparty of such failure.

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

            Any Swap Termination Payment received from the Swap Counterparty
shall be used to pay any upfront amount required under any replacement swap
contract and any excess shall be distributed to CHL and will not be available
to make distributions in respect of any Class of Certificates. In the event
that a replacement swap contract cannot be procured, any Swap Termination
Payment received from the Swap Counterparty in respect of the termination of
the original Swap Contract shall, in accordance with the Swap Contract
Administration Agreement, be retained by the Swap Contract Administrator and
remitted to the Swap Trustee on subsequent Distribution Dates up to and
including the Swap Contract Termination Date to pay any amounts distributable
to the Interest-Bearing Certificates pursuant to Section 4.04(d)(3) through
(8) that will remain unpaid following all distributions to be made on such
Distribution Date pursuant to Section 4.04(a) through (c). Any portion of such
upfront amount remaining after the Swap Contract Termination Date shall be
distributed to CHL and will not be available to make distributions in respect
of any Class of Certificates.

            In the event that the swap counterparty in respect of a replacement
swap contract pays any upfront amount to the Swap Contract Administrator in
connection with entering into the replacement swap contract and such upfront
amount is received by the Swap Contract Administrator prior to the Distribution
Date on which any Swap Termination Payment will be payable to the Swap
Counterparty in respect of the original Swap Contract, a portion of that upfront
amount equal to the lesser of (x) that upfront amount and (y) the amount of the
Swap Termination Payment due to the Swap Counterparty in respect of the original
Swap Contract (the "Adjusted Replacement Upfront Amount") shall be included in
Interest Funds for Loan Group 1 and Loan Group 2 for that Distribution Date, pro
rata, based upon their respective Interest Funds for that Distribution Date, and
any upfront amount in excess of the Adjusted

                                      113
<PAGE>

Replacement Upfront Amount shall be distributed to CHL and will not be
available to make distributions in respect of any Class of Certificates. Any
upfront amount paid to the Swap Contract Administrator by the swap
counterparty in respect of a replacement swap contract after the Distribution
Date on which any Swap Termination Payment will be payable to the Swap
Counterparty in respect of the original Swap Contract, such upfront amount

                                 ARTICLE IV.
              DISTRIBUTIONS AND ADVANCES BY THE MASTER SERVICER

            Section 4.01      Advances; Remittance Reports.

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

            (b) Subject to the conditions of this Article IV, the Master
Servicer, as required below, shall make an Advance and deposit such Advance in
the Certificate Account. Each such Advance shall be remitted to the Certificate
Account no later than 1:00 p.m. Pacific time on the Master Servicer Advance Date
in immediately available funds. The Trustee will provide notice to the Master
Servicer by facsimile by the close of business on any Master Servicer Advance
Date in the event that the amount remitted by the Master Servicer to the Trustee
on the Distribution Account Deposit Date is less than the Advances required to
be made by the Master Servicer for such Distribution Date. The Master Servicer
shall be obligated to make any such Advance only to the extent that such advance
would not be a Nonrecoverable Advance. If the Master Servicer shall have
determined that it has made a Nonrecoverable Advance or that a proposed Advance
or a lesser portion of such Advance would constitute a Nonrecoverable Advance,
the Master Servicer shall deliver (i) to the Trustee for the benefit of the
Certificateholders funds constituting the remaining portion of such Advance, if
applicable, and (ii) to the Depositor, each Rating Agency and the Trustee an
Officer's Certificate setting forth the basis for such determination.

                                      114
<PAGE>

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

            (d) If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to give
written notice thereof to the Trustee (each such notice a "Trustee Advance
Notice"; and such notice may be given by facsimile), not later than 3:00 p.m.,
New York time, on the Business Day immediately preceding the related Master
Servicer Advance Date, specifying the amount that it will be unable to deposit
(each such amount an "Advance Deficiency") and certifying that such Advance
Deficiency constitutes an Advance hereunder and is not a Nonrecoverable Advance.
If the Trustee receives a Trustee Advance Notice on or before 3:30 p.m., (New
York time) on a Master Servicer Advance Date, the Trustee shall, not later than
3:00 p.m., (New York time), on the related Distribution Date, deposit in the
Distribution Account an amount equal to the Advance Deficiency identified in
such Trustee Advance Notice unless it is prohibited from so doing by applicable
law. Notwithstanding the foregoing, the Trustee shall not be required to make
such deposit if the Trustee shall have received written notification from the
Master Servicer that the Master Servicer has deposited or caused to be deposited
in the Certificate Account an amount equal to such Advance Deficiency. All
Advances made by the Trustee pursuant to this Section 4.01(d) shall accrue
interest on behalf of the Trustee at the Trustee Advance Rate from and including
the date such Advances are made to but excluding the date of repayment, with
such interest being an obligation of the Master Servicer and not the Trust Fund.
The Master Servicer shall reimburse the Trustee for the amount of any Advance
made by the Trustee pursuant to this Section 4.01(d) together with accrued
interest, not later than 6:00 p.m. (New York time) on the Business Day following
the related Distribution Date. In the event that the Master Servicer does not
reimburse the Trustee in accordance with the requirements of the preceding
sentence, the Trustee shall immediately (i) terminate all of the rights and
obligations of the Master Servicer under this Agreement in accordance with
Section 7.01 and (ii) subject to the limitations set forth in Section 3.04,
assume all of the rights and obligations of the Master Servicer hereunder.

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

                                      115

The Master Servicer shall deliver to the Trustee on the related Master Servicer
Advance Date an Officer's Certificate of a Servicing Officer indicating the
amount of any proposed Advance determined by the Master Servicer to be a
Nonrecoverable Advance.

                              with Prepayment Interest Shortfalls.

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

            (g) On each Distribution Date, the Trustee shall allocate any
Applied Realized Loss Amount to reduce the Certificate Principal Balances of the
Class B, Class M-9, Class M-8, Class M-7, Class M-6, Class M-5, Class M-4, Class
M-3, Class M-2 and Class M-1 Certificates, sequentially, in that order, in each
case until the Certificate Principal Balance thereof is reduced to zero. After
the Certificate Principal Balances of the Subordinate Certificates have been
reduced to zero, (i) the Trustee shall allocate any Applied Realized Loss Amount
with respect to Loan Group 1 to reduce the Certificate Principal Balance of the
Class 1-A Certificates, until the Certificate Principal Balance of such Class
has been reduced to zero, and (ii) the Trustee shall allocate any Applied
Realized Loss Amount with respect to Loan Group 2 to reduce the Certificate
Principal Balances of each Class of Class 2-A Certificates, on a pro rata basis
according to their respective Certificate Principal Balances, until the
Certificate Principal Balances of such Classes have been reduced to zero.

            (h) On each Distribution Date, the Trustee shall allocate the amount
of the Subsequent Recoveries with respect to either Loan Group, if any, first to
increase the Certificate Principal Balance of the Class 1-A Certificates (in the
case of any Subsequent Recoveries with respect to Loan Group 1) or the
Certificate Principal Balances of the Classes of Class 2-A Certificates (in the
case of any Subsequent Recoveries with respect to Loan Group 2) to which Applied
Realized Loss Amounts have been previously allocated (such increases, in the
case of Subsequent Recoveries with respect to Loan Group 2, to be made among the
Classes of Class 2-A Certificates on a pro rata basis according to their
respective Certificate Principal Balances), in each case by not more than the
amount of the Unpaid Realized Loss Amount of such Class, and then to increase
the Certificate Principal Balance of the Subordinate Certificates to which
Applied Realized Loss Amounts have been previously allocated, sequentially, to
the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7,
Class M-8, Class M-9 and Class B Certificates, in that order, in each case by
not more than the amount of the Unpaid Realized Loss Amount of such Class.

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

            Subject to Section 9.02 hereof respecting the final distribution, on
each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire transfer
in immediately available funds to the account of such Holder at a bank or other
entity having appropriate facilities therefor, if (i) such Holder has so
notified the Trustee at least five Business Days prior to the related Record
Date and (ii) such Holder shall hold Regular Certificates with an aggregate
initial Certificate Principal Balance of not less than $1,000,000 or evidencing
a Percentage Interest aggregating 10% or more with respect to such Class or, if
not, by check mailed by first class mail to such Certificateholder at the
address of such Holder appearing in the Certificate Register. Notwithstanding
the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the name
of a Depository shall be made to such Depository in immediately available funds.

            On or before 5:00 p.m. Pacific time on the fifth Business Day
following each Determination Date (but in no event later than 5:00 p.m. Pacific
time on the third Business Day

before the related Distribution Date), the Master Servicer shall deliver a
report to the Trustee (in the form of a computer readable magnetic tape or by
such other means as the Master Servicer and the Trustee may agree from time to
time) containing such data and information as agreed to by the Master Servicer
and the Trustee (including, without limitation, the actual mortgage rate for
each Credit Comeback Loan) such as to permit the Trustee to prepare the Monthly
Statement and make the required distributions for the related Distribution Date
(the "Remittance Report"). The Trustee shall not be responsible to recompute,
recalculate or verify information provided to it by the Master Servicer and
shall be permitted to conclusively rely on any information provided to it by the
Master Servicer.

            (i) On the earlier of (i) the Distribution Date in November 2036 and
(ii) the termination of this Agreement pursuant to Section 9.01, after giving
effect to the distribution of all available funds, all amounts on deposit in the
Final Maturity Reserve Fund will be distributed in the following order of
priority:

                  (1) to the Classes of Class A Certificates, pro rata, based on
      the Class 1-A Principal Distribution Amount (in the case of clause (x))
      and the Class 2-A Principal Distribution Amount (in the case of clause
      (y)), concurrently: (x) to the Class 1-A Certificates, until the
      Certificate Principal Balance thereof is reduced to zero, and (y)
      sequentially, to the Class 2-A-1, Class 2-A-2, Class 2-A-3 and Class 2-A-4
      Certificates, in that order, in each case, until the Certificate Principal
      Balance thereof is reduced to zero; provided, however, that any amounts
      remaining after such allocation based on the Class 1-A Principal
      Distribution Amount and the Class 2-A Principal Distribution Amount will
      be distributed to the outstanding Class 1-A Certificates or the
      outstanding Classes of Class 2-A Certificates, as the case may be,
      pursuant to clause (x) or clause (y), as the case may be; and

                  (2) sequentially, to the Class M-1, Class M-2, Class M-3,
      Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class
      B Certificates, in that order, until the Certificate Principal Balances
      thereof are reduced to zero; and

                  (3) to the Class C Certificates, all remaining amounts.

            Section 4.05      Monthly Statements to Certificateholders.

            (a) Concurrently with each distribution on a Distribution Date, the
Trustee will forward by mail to each Rating Agency and make available to
Certificateholders on the Trustee's website

information contained in Exhibit W.

            (b) The Trustee's responsibility for disbursing the above
information to the Certificateholders is limited to the availability, timeliness
and accuracy of the information derived from the Master Servicer. The Trustee
shall send a copy of each statement provided pursuant to this Section 4.05 to
each Rating Agency and the NIM Insurer. The Trustee may make the above
information available to Certificateholders via the Trustee's website at

            (c) Within a reasonable period of time after the end of each
calendar year, the Trustee shall cause to be furnished to each Person who at any
time during the calendar year was a Certificateholder, a statement containing
the information regarding (i) the amount of distributions to that
Certificateholder allocable to principal, separately identifying (A) the
aggregate amount of any Principal Prepayments included therein and (B) the
aggregate of all scheduled payments of principal included therein, (ii) the
amount of distributions to that Certificateholder allocable to interest and
(iii) the related amount of the Servicing Fees paid to or retained by the Master
Servicer, in each case aggregated for such calendar year or applicable portion
thereof during which such Person was a Certificateholder. Such obligation of the
Trustee shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Trustee pursuant to any
requirements of the Code as from time to time in effect.

            (d) Upon filing with the Internal Revenue Service, the Trustee shall
furnish to the Holders of the Class A-R Certificates the Form 1066 and each Form
1066Q and shall respond promptly to written requests made not more frequently

      together with each constant yield to maturity used in computing the same;

            The information pursuant to clauses (1), (2), (3)and (4) above shall

            Section 4.06      Termination of the Mortgage Insurance Policy
                              Issued by Mortgage Guaranty Insurance Corporation.

            If on any given date the rating of Mortgage Guaranty Insurance
Corporation's claims-paying ability is downgraded below and remains below "AA-"
from S&P or "Aa3" from Moody's, the Master Servicer may direct the Co-Trustee to
terminate the Mortgage Insurance Policy issued by Mortgage Guaranty Insurance
Corporation and the Co-Trustee shall act in accordance with such direction. The
Master Servicer hereby covenants and agrees that it will not direct the
Co-Trustee to exercise its right to terminate such Mortgage Insurance Policy
unless the Co-Trustee obtains a mortgage insurance policy that meets the
following conditions: (i) such mortgage insurance policy must be issued by a
mortgage insurer that has a rating with respect to its claims-paying ability at
or above "AA " from S&P or "Aa3" from Moody's and (ii) such mortgage insurance
policy must cover the related Covered Mortgage Loans outstanding as of such
date.

            In addition, if during the period which the Depositor is required to
file Exchange Act Reports with respect to the Trust Fund, either (a) Mortgage
Guaranty Insurance Corporation shall fail to provide to CHL any information
required to be provided pursuant to Section 2(b) of the Item 1114 Agreement,
dated as of November 7, 2006, between CHL, the Depositor, CWMBS, Inc., CWALT,
Inc., CWHEQ, Inc. and Mortgage Guaranty Insurance Corporation, within the time
period required by such agreement, or (b) United Guaranty Mortgage Indemnity
Company shall fail to provide to CHL any information reasonably requested by CHL
for the purposes of compliance with Item 1114 of Regulation AB, then the
Co-Trustee shall act at the written direction of the Depositor as to whether to
terminate the applicable Mortgage Insurance Policy; provided, however, that the
Co-Trustee shall provide written notice to each Rating Agency of any such
termination. Upon the termination of such Mortgage Insurance Policy under the
circumstances contemplated by this paragraph, CHL shall assist the Co-Trustee in
procuring a replacement mortgage insurance policy that meets the criteria for a
replacement mortgage insurance policy specified in the preceding paragraph.

            Section 4.07      Carryover Reserve Fund.

            (a) On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of the Holders of the Certificates, the

Fund shall be an Eligible Account, and funds on deposit therein shall be held
separate and apart from, and shall not be commingled with, any other moneys,

the Carryover Reserve Fund for federal tax purposes.

            (d) Funds in the Carryover Reserve Fund shall be invested by the
Trustee in The Bank of New York cash reserves. All investments shall be made in

            Section 4.08      Credit Comeback Excess Account.

direction of the Majority Holder of the Class C Certificates, which Permitted
Investments shall mature not later than the Business Day immediately preceding

maintains the Credit Comeback Excess Account, then such Permitted Investment
shall mature not later than such Distribution Date) and shall not be sold or
disposed of prior to maturity. All such Permitted Investments shall be made in
the name of the Trustee, for the benefit of the Certificateholders. In the
absence of such written direction, all funds in the Credit Comeback Excess
Account shall be invested by the Trustee in The Bank of New York cash reserves.
Any net investment earnings on amounts in the Credit Comeback Excess Account
with respect to Loan Group 1 and Loan Group 2 shall be payable pro rata to the
Holders of the Class C Certificates in accordance with their Percentage
Interests. Any losses incurred in the Credit Comeback Excess Account in respect
of any such investments shall be charged against amounts on deposit in the
Credit Comeback Excess Account (or such investments) immediately as realized.

            The Trustee shall not be liable for the amount of any loss incurred
in respect of any investment or lack of investment of funds held in the Credit
Comeback Excess Account and made in accordance with this Section 4.08. The
Credit Comeback Excess Account shall not constitute an asset of any REMIC
created hereunder. The Class C Certificates shall evidence ownership of the
Credit Comeback Excess Account for federal tax purposes.

            On the Closing Date, there is hereby established a separate trust
(the "Swap Trust"), the assets of which shall consist of the Trustee's rights
and obligations under the Swap Contract Administration Agreement. The Swap Trust
shall be maintained by the Swap Trustee, who initially, shall be the Trustee.
The Swap Trustee shall hold the assets of the Swap Trust in trust for the
benefit of the Holders of the Interest-Bearing Certificates and the Swap
Counterparty. No later than the Closing Date, the Swap Trustee shall establish
and maintain a separate, segregated trust account to be held in the Swap Trust,

Remittance Amounts, such additional amount as is necessary to cover the

            Funds in the Final Maturity Reserve Fund may be invested in
Permitted Investments at the direction of the Holders of the Class C
Certificates, which Permitted Investments shall mature not later than the
Business Day immediately preceding the first Distribution Date that follows the
date of such investment (except that if such Permitted Investment is an
obligation of the institution that maintains the Final Maturity Reserve Fund,
then such Permitted Investment shall mature not later than such Distribution
Date) and shall not be sold or disposed of prior to maturity. All such Permitted
Investments shall be made in the name of the Final Maturity Reserve Trustee, for
the benefit of the Holders of the Certificates. In the absence of such written
direction, all funds in the Final Maturity Reserve Fund shall be invested by the
Final Maturity Reserve Trustee in The Bank of New York cash reserves. Any net

of any loss incurred in respect of any investment or lack of investment of funds
held in the Final Maturity Reserve Fund and made in accordance with this Section
4.10.

            The Final Maturity Reserve Trustee may withhold from the amounts
withdrawn from the Final Maturity Reserve Fund pursuant to Section 4.04 the
amount of any taxes that it is authorized to retain pursuant to the third
paragraph of Section 8.11. In addition, the Final Maturity Reserve Trustee may
from time to time make withdrawals from the Final Maturity Reserve Fund for the
following purposes:

            (i) to withdraw any amount deposited in the Final Maturity Reserve
Fund and not required to be deposited therein; and

any Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication. On the Closing
Date, the Trustee shall authenticate the Certificates to be issued at the
written direction of the Depositor, or any affiliate thereof.

                                      129

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

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

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

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

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

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

            (b) No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such state securities laws, in order to assure
compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such Certificateholder's
prospective transferee shall (except in connection with any transfer of a
Private Certificate to an affiliate of the Depositor (either directly or through
a nominee) in connection with the initial issuance of the Certificates) each
certify to the Trustee in writing the facts surrounding the Transfer in
substantially the form set forth in Exhibit J-2 (a "Transferor Certificate") and
(i) deliver a letter in substantially the form of either Exhibit K (in the case
of the Class P and Class C Certificates and in the case of a Class B Certificate
that after the proposed transfer will be a Definitive Certificate) (the
"Investment Letter") or Exhibit L (in the case of any Private Certificate) (the
"Rule 144A Letter") or (ii) there shall be delivered to the Trustee at the
expense of the Certificateholder desiring to effect such transfer an Opinion of

                                      130
<PAGE>

Counsel that such Transfer may be made pursuant to an exemption from the
Securities Act; provided, however, that in the case of the delivery of an
Investment Letter in connection with the transfer of any Class C or Class P
Certificate to a transferee that is formed with the purpose of issuing notes
backed by such Class C or Class P Certificate, as the case may be, clause (b)
and (c) of the form of Investment Letter shall not be applicable and shall be
deleted by such transferee. The Depositor shall provide to any Holder of a
Private Certificate and any prospective transferee designated by any such
Holder, information regarding the related Certificates and the Mortgage Loans
and such other information as shall be necessary to satisfy the condition to
eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate
without registration thereof under the Securities Act pursuant to the
registration exemption provided by Rule 144A. The Co-Trustee, the Trustee and
the Master Servicer shall cooperate with the Depositor in providing the Rule
144A information referenced in the preceding sentence, including providing to
the Depositor such information regarding the Certificates, the Mortgage Loans
and other matters regarding the Trust Fund as the Depositor shall reasonably
request to meet its obligation under the preceding sentence. Each Holder of a
Private Certificate desiring to effect such Transfer shall, and does hereby
agree to, indemnify the Co-Trustee, the Trustee, the Depositor, the Trust Fund,
each Seller, the Master Servicer and the NIM Insurer against any liability that
may result if the Transfer is not so exempt or is not made in accordance with
such federal and state laws.

            No beneficial interest in any Class B Certificate that is a
Book-Entry Certificate may be held by any Person that is not a Qualified
Institutional Buyer. Notwithstanding the foregoing, a beneficial interest in a
Class B Certificate that is a Book-Entry Certificate may be transferred by any
Certificate Owner holding such interest to any Institutional Accredited Investor
(other than a Qualified Institutional Buyer) that takes delivery in the form of
a Definitive Certificate upon delivery to the Trustee of (i) such certifications
and/or opinions as are contemplated by the first paragraph of this Section
5.02(b) and (ii) such written orders and instructions as are required under the
applicable procedures of the Depository to direct the Trustee to debit the
account of a Depository Participant by the denomination of the transferred
interests in such Book-Entry Certificate. Upon delivery to the Trustee of the
certifications and/or opinions contemplated by the first paragraph of this
Section 5.02(b), the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall reduce the denomination of the subject
Book-Entry Certificate by the denomination of the transferred interests in such
Book-Entry Certificate, and shall cause a Definitive Certificate of the same
Class as such Book-Entry Certificate, and in a denomination equal to the
reduction in the denomination of such Book-Entry Certificate, to be executed,
authenticated and delivered in accordance with this Agreement to the applicable
transferee. Also notwithstanding the foregoing, any Class B Certificate that is
a Definitive Certificate may be transferred by any Certificateholder holding
such Certificate to any Qualified Institutional Buyer that takes delivery in the
form of a beneficial interest in a Book-Entry Certificate upon delivery to the
Trustee of (i) such certifications and/or opinions as are contemplated by the
first paragraph of this Section 5.02(b) and (ii) such written orders and
instructions as are required under the applicable procedures of the Depository
to direct the Trustee to credit the account of a Depository Participant by the
denomination of the transferred interests in such Class B Certificate. Upon
delivery to the Trustee of the Definitive Certificate to be transferred and the
certifications and/or opinions contemplated by the first paragraph of this
Section 5.02(b), the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall increase the denomination of the existing
Book-Entry Certificate for the Class

                                      131
<PAGE>

B Certificates by the denomination of the transferred interests in such
Definitive Certificate, shall instruct the Depository to credit the account of
the applicable Depository Participant, and shall cause the subject Definitive
Certificate to be cancelled.

            No Transfer of an ERISA-Restricted Certificate (other than a
transfer of an ERISA-Restricted Certificate to an affiliate of the Depositor
(either directly or through a nominee) in connection with the initial issuance
of the Certificates) shall be made unless the Trustee shall have received either
(i) a written representation from the transferee of such Certificate acceptable
to and in form and substance satisfactory to the Trustee (in the event such
Certificate is a Private Certificate, such requirement is satisfied only by the
Trustee's receipt of a representation letter from the transferee substantially
in the form of Exhibit K or Exhibit L, or in the event such Certificate is a
Residual Certificate, such requirement is satisfied only by the Trustee's
receipt of a representation letter from the transferee substantially in the form
of Exhibit I), to the effect that (x) such transferee is not a Plan, or (y) in
the case of an ERISA-Restricted Certificate that has been the subject of an
ERISA-Qualifying Underwriting, a representation that the transferee is an
insurance company which is purchasing such Certificate with funds contained in
an "insurance company general account" (as such term is defined in section V(e)
of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the
purchase and holding of such Certificate satisfy the requirements for exemptive
relief under Sections I and III of PTCE 95-60 or (ii) in the case of any
ERISA-Restricted Certificate presented for registration in the name of an
employee benefit plan or arrangement subject to ERISA, or a plan or arrangement
subject to Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or arrangement or any other person
acting on behalf of any such plan or arrangement, an Opinion of Counsel
satisfactory to the Trustee, addressed to the Trustee and the Master Servicer,
to the effect that the purchase or holding of such ERISA-Restricted Certificate
will not result in a non-exempt prohibited transaction under ERISA or the Code
and will not subject the Trustee or the Master Servicer to any obligation in
addition to those expressly undertaken in this Agreement, which Opinion of
Counsel shall not be an expense of the Trustee, the Master Servicer, or the
Trust Fund. For purposes of the preceding sentence, one of such representations,
as appropriate, shall be deemed to have been made to the Trustee by the
transferee's acceptance of an ERISA-Restricted Certificate (or the acceptance by
a Certificate Owner of the beneficial interest in any such Class of
ERISA-Restricted Certificates) unless the Trustee shall have received from the
transferee an Opinion of Counsel as described in clause (ii) or a written
representation acceptable in form and substance to the Trustee. Notwithstanding
anything else to the contrary herein, any purported transfer of an
ERISA-Restricted Certificate to or on behalf of an employee benefit plan subject
to Section 406 of ERISA or a plan subject to Section 4975 of the Code without
the delivery to the Trustee of an Opinion of Counsel satisfactory to the Trustee
meeting the requirements of clause (i) of the first sentence of this paragraph
as described above shall be void and of no effect. The Trustee shall be under no
liability to any Person for any registration of transfer of any ERISA-Restricted
Certificate that is in fact not permitted by this Section 5.02(b) or for making
any payments due on such Certificate to the Holder thereof or taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the Trustee, with respect to the transfer of such Classes of
Certificates, required delivery of such certificates and other documentation or
evidence as are expressly required by the terms of this Agreement and examined
such certificates and other documentation or evidence to determine compliance as
to form with the express requirements hereof. The Trustee shall be entitled, but
not obligated, to recover from any Holder of any

                                      132
<PAGE>

ERISA-Restricted Certificate that was in fact an employee benefit plan or
arrangement subject to Section 406 of ERISA or a plan or arrangement subject to
Section 4975 of the Code or a Person acting on behalf of any such plan or
arrangement at the time it became a Holder or, at such subsequent time as it
became such a plan or arrangement or Person acting on behalf of such a plan or
arrangement, all payments made on such ERISA-Restricted Certificate at and after
either such time. Any such payments so recovered by the Trustee shall be paid
and delivered by the Trustee to the last preceding Holder of such Certificate
that is not such a plan or arrangement or Person acting on behalf of a plan or
arrangement.

            Until the Swap Trust and the Final Maturity Reserve Fund terminate,
no transfer of an Interest-Bearing Certificate (other than a transfer of an
Interest-Bearing Certificate to an affiliate of the Depositor (either directly
or through a nominee) in connection with the initial issuance of the
Certificates) shall be made unless the Trustee shall have received either (i) a
written representation from the transferee of such Interest-Bearing Certificate
acceptable to and in form and substance satisfactory to the Trustee to the
effect that such transferee is not a Plan, or (ii) a written representation that
the purchase and holding of the Interest-Bearing Certificate satisfy the
requirements for exemptive relief under PTCE 84-14, PTCE 90-1, PTCE 91-38, PTCE
95-60, PTCE 96-23, the service provider exemption provided under Section 408
(b)(17) of ERISA and Section 4975 (d)(20) of the Code or a similar exemption. In
the event that such representation is not delivered, one of the foregoing
representations, as appropriate, shall be deemed to have been made by the
transferee's (including an initial acquiror's) acceptance of the
Interest-Bearing Certificate. In the event that such representation is violated,
such transfer or acquisition shall be void and of no effect.

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

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

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

                  (3) Each Person holding or acquiring any Ownership Interest in
      a Class A-R Certificate shall agree (A) to obtain a Transfer Affidavit
      from any other Person to whom such Person attempts to Transfer its
      Ownership Interest in a Class A-R Certificate, (B) to obtain a Transfer
      Affidavit from any Person for whom such Person is

                                      133
<PAGE>

      acting as nominee, trustee or agent in connection with any Transfer of a
      Class A-R Certificate and (C) not to Transfer its Ownership Interest in a
      Class A-R Certificate, or to cause the Transfer of an Ownership Interest
      in a Class A-R Certificate to any other Person, if it has actual knowledge
      that such Person is not a Permitted Transferee or that such Transfer
      Affidavit is false.

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

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

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

                                      134
<PAGE>

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

            Section 5.03      Mutilated, Destroyed, Lost or Stolen Certificates.

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

            Section 5.04      Persons Deemed Owners.

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

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

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

            Section 5.06      Book-Entry Certificates.

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

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

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

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

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

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

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

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

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

            Section 5.07      Notices to Depository.

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

            Section 5.08      Definitive Certificates.

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

            Section 5.09      Maintenance of Office or Agency.

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

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

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

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

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

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

partnership in each jurisdiction in which such qualification or registration is
or shall be necessary to protect the validity and enforceability of this
Agreement or any of the Mortgage Loans and to perform its duties under this
Agreement.

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

            As a condition to the effectiveness of any merger or consolidation,
at least 15 calendar days prior to the effective date of any merger or
consolidation of the Master Servicer, the Master Servicer shall provide (x)
written notice to the Depositor of any successor pursuant to this Section and
(y) in writing and in form and substance reasonably satisfactory to the
Depositor, all information reasonably requested by the Depositor in order to
comply with its reporting obligation under Item 6.02 of Form 8-K with respect to

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

            None of the Depositor, the Sellers, the NIM Insurer or the Master
Servicer or any of the directors, officers, employees or agents of the
Depositor, the Sellers, the NIM Insurer or the Master Servicer shall be under
any liability to the Trustee (except as provided in Section

                                      138
<PAGE>

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

            Section 6.04      Limitation on Resignation of Master Servicer.

            The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except (i) upon determination that its duties hereunder are
no longer permissible under applicable law or (ii) upon appointment of a
successor servicer that is reasonably acceptable to the Trustee and the NIM
Insurer and the written confirmation from each Rating Agency (which confirmation
shall be furnished to the Depositor, the Trustee and the NIM Insurer) that such
resignation will not cause such Rating Agency to reduce the then-current rating
of the Certificates. Any such determination pursuant to clause (i) of the
preceding sentence permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No
resignation of the Master Servicer shall become effective until the Trustee
shall have assumed the Master Servicer's responsibilities, duties, liabilities
(other than those liabilities arising prior to the appointment of such
successor) and obligations under this Agreement and the Depositor shall have
received the information described in the following sentence. As a condition to
the effectiveness of any such resignation, at least 15 calendar days prior to
the effective date of such resignation, the Master Servicer shall

                                      139
<PAGE>

provide (x) written notice to the Depositor of any successor pursuant to this
Section and (y) in writing and in form and substance reasonably satisfactory to
the Depositor, all information reasonably requested by the Depositor in order to
comply with its reporting obligation under Item 6.02 of Form 8-K with respect to
the resignation of the Master Servicer.

            Section 6.05      Errors and Omissions Insurance; Fidelity Bonds.

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

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

                                  ARTICLE VII.
                     DEFAULT; TERMINATION OF MASTER SERVICER

            Section 7.01      Events of Default.

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

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

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

                                      140
<PAGE>

      Holders of Certificates evidencing not less than 25% of the Voting Rights;
      provided, that the sixty-day cure period shall not apply to the initial
      delivery of the Mortgage File for Delay Delivery Mortgage Loans or the
      failure to repurchase or substitute in lieu thereof; or

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

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

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

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

            If an Event of Default shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
shall, but only at the direction of either the NIM Insurer or the Holders of
Certificates evidencing not less than 25% of the Voting Rights, by notice in
writing to the Master Servicer (with a copy to each Rating Agency and the
Depositor), terminate all of the rights and obligations of the Master Servicer
under this Agreement and in and to the Mortgage Loans and the proceeds thereof,
other than its rights as a Certificateholder hereunder. In addition, if during
the period that the Depositor is required to file Exchange Act Reports with
respect to the Trust Fund, the Master Servicer shall fail to observe or perform
any of the obligations that constitute a Limited Exchange Act Reporting
Obligation or the obligations set forth in Section 3.17(a) or Section
11.07(a)(1) and (2), and such failure continues for the lesser of 10 calendar
days or such period in which the applicable Exchange Act Report can be filed
timely (without taking into account any extensions), so long as such failure
shall not have been remedied, the Trustee shall, but only at the direction of
the Depositor, terminate all of the rights and obligations of the Master
Servicer under this Agreement and in and to the Mortgage Loans and the proceeds
thereof, other than its rights as a Certificateholder hereunder. The Depositor
shall not be entitled to terminate the rights and obligations of the Master
Servicer if a failure of the Master Servicer to identify a Subcontractor
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB was attributable

                                      141
<PAGE>

solely to the role or functions of such Subcontractor with respect to mortgage
loans other than the Mortgage Loans.

            On or after the receipt by the Master Servicer of such written
notice, all authority and power of the Master Servicer hereunder, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in the
Trustee. The Trustee shall thereupon make any Advance described in Section 4.01
hereof subject to Section 3.04 hereof. The Trustee is hereby authorized and
empowered to execute and deliver, on behalf of the Master Servicer, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such termination
shall affect any obligation of the Master Servicer to pay amounts owed pursuant
to Article VIII. The Master Servicer agrees to cooperate with the Trustee in
effecting the termination of the Master Servicer's responsibilities and rights
hereunder, including, without limitation, the transfer to the Trustee of all
cash amounts which shall at the time be credited to the Certificate Account, or
thereafter be received with respect to the Mortgage Loans. The Trustee shall
promptly notify the Rating Agencies and the Depositor of the occurrence of an
Event of Default.

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

            If the Master Servicer is terminated, the Trustee shall provide the
Depositor in writing and in form and substance reasonably satisfactory to the
Depositor, all information reasonably requested by the Depositor in order to
comply with its reporting obligation under Item 6.02 of Form 8-K with respect to
a successor master servicer in the event the Trustee should succeed to the
duties of the Master Servicer as set forth herein.

            Section 7.02      Trustee to Act; Appointment of Successor.

            On and after the time the Master Servicer receives a notice of
termination pursuant to Section 7.01 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Master Servicer in its
capacity as servicer under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof and applicable law including the obligation to make advances
pursuant to Section 4.01. As compensation therefor, the Trustee shall be
entitled to all fees, costs and expenses relating to the Mortgage Loans that the
Master Servicer would have been entitled to if the Master Servicer had continued
to act hereunder. Notwithstanding the foregoing, if the Trustee has become the
successor to the Master Servicer in accordance with Section 7.01 hereof, the
Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited
by applicable law from making Advances

                                      142
<PAGE>

pursuant to Section 4.01 hereof or if it is otherwise unable to so act, (i)
appoint any established mortgage loan servicing institution reasonably
acceptable to the NIM Insurer (as evidenced by the prior written consent of the
NIM Insurer), or (ii) if it is unable for 60 days to appoint a successor
servicer reasonably acceptable to the NIM Insurer, petition a court of competent
jurisdiction to appoint any established mortgage loan servicing institution, the
appointment of which does not adversely affect the then-current rating of the
Certificates and the NIM Insurer guaranteed notes (without giving any effect to
any policy or guaranty provided by the NIM Insurer) by each Rating Agency as the
successor to the Master Servicer hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer hereunder.
Any successor Master Servicer shall be an institution that is a Fannie Mae and
Freddie Mac approved seller/servicer in good standing, that has been approved by
each Mortgage Insurer if required, that has a net worth of at least $15,000,000
and that is willing to service the Mortgage Loans and executes and delivers to
the Depositor and the Trustee an agreement accepting such delegation and
assignment, that contains an assumption by such Person of the rights, powers,
duties, responsibilities, obligations and liabilities of the Master Servicer
(other than liabilities and indemnities of the Master Servicer under Section
6.03 hereof incurred prior to termination of the Master Servicer under Section
7.01), with like effect as if originally named as a party to this Agreement; and
provided further that each Rating Agency acknowledges that its rating of the
Certificates in effect immediately prior to such assignment and delegation will
not be qualified or reduced as a result of such assignment and delegation. No
appointment of a successor to the Master Servicer hereunder shall be effective
until (i) the Trustee shall have consented thereto, (ii) written notice of such
proposed appointment shall have been provided by the Trustee to each
Certificateholder and (iii) at least 15 calendar days prior to the effective
date of such appointment, (x) the Trustee shall provide written notice to the
Depositor of such successor pursuant to this Section 7.02 and (y) such successor
Master Servicer shall provide to the Depositor in writing and in form and
substance reasonably satisfactory to the Depositor, all information reasonably
requested by the Depositor in order to comply with its reporting obligation
under Item 6.02 of Form 8-K with respect to a replacement master servicer. The
Trustee shall not resign as servicer until a successor servicer has been
appointed and has accepted such appointment. Pending appointment of a successor
to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited
by law from so acting, shall, subject to Section 3.04 hereof, act in such
capacity as herein above provided. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of such
successor out of payments on Mortgage Loans as it and such successor shall
agree; provided that no such compensation shall be in excess of that permitted
the Master Servicer hereunder. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession. Neither the Trustee nor any other successor servicer shall be
deemed to be in default hereunder by reason of any failure to make, or any delay
in making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either case caused by the failure of the Master Servicer to deliver or
provide, or any delay in delivering or providing, any cash, information,
documents or records to it.

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

                                      143
<PAGE>

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

            Section 7.03      Notification to Certificateholders.

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

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

                                  ARTICLE VIII.
                    CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

            Section 8.01      Duties of Trustee.

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

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

                                      144
<PAGE>

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

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

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

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

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

            The Trustee hereby represents, warrants, covenants and agrees that,
except as permitted by Article IX hereof, it shall not cause the Trust Fund to
consolidate or amalgamate with, or merge with or into, or transfer all or
substantially all of the Trust Fund to, another Person.

            Section 8.02      Certain Matters Affecting the Trustee.

            (a) Except as otherwise provided in Section 8.01:

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

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

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

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

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

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

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

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

                                      146
<PAGE>

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

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

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

            Section 8.03      Trustee Not Liable for Mortgage Loans.

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

            Section 8.04      Trustee May Own Certificates.

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

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

            The Master Servicer covenants and agrees to pay or reimburse the
Trustee, upon its request, for all reasonable expenses, disbursements and
advances incurred or made by the Trustee on behalf of the Trust Fund in
accordance with any of the provisions of this Agreement

                                      147
<PAGE>

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

            Section 8.06      Eligibility Requirements for Trustee.

            The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07 hereof. The corporation or
national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor, the Sellers and the Master Servicer and
their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.

            Section 8.07      Resignation and Removal of Trustee.

            The Trustee may at any time resign and be discharged from the trusts
hereby created by (1) giving written notice of resignation to the Depositor and
the Master Servicer and by mailing notice of resignation by first class mail,
postage prepaid, to the Certificateholders at their addresses appearing on the
Certificate Register and each Rating Agency, not less than 60 days before the
date specified in such notice when, subject to Section 8.08, such resignation is
to take effect, and (2) acceptance of appointment by a successor trustee in
accordance with Section

                                      148
<PAGE>

8.08 and meeting the qualifications set forth in Section 8.06. If no successor
trustee shall have been so appointed and have accepted appointment within 30
days after the giving of such notice or resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
trustee.

            As a condition to the effectiveness of any such resignation, at
least 15 calendar days prior to the effective date of such resignation, the
Trustee shall provide (x) written notice to the Depositor of any successor
pursuant to this Section and (y) in writing and in form and substance reasonably
satisfactory to the Depositor, all information reasonably requested by the
Depositor in order to comply with its reporting obligation under Item 6.02 of
Form 8-K with respect to the resignation of the Trustee.

            If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 hereof and shall fail to resign
after written request thereto by the NIM Insurer or the Depositor, (ii) the
Trustee shall become incapable of acting, or shall be adjudged as bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed,
or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, (iii)(A) a tax is imposed with respect to the Trust Fund by any
state in which the Trustee or the Trust Fund is located, (B) the imposition of
such tax would be avoided by the appointment of a different trustee and (C) the
Trustee fails to indemnify the Trust Fund against such tax, or (iv) during the
period which the Depositor is required to file Exchange Act Reports with respect
to the Trust Fund, the Trustee fails to comply with its obligations under the
last sentence of Section 7.01, the preceding paragraph, Section 8.09 or Article
XI and such failure is not remedied within the lesser of 10 calendar days or
such period in which the applicable Exchange Act Report can be filed timely
(without taking into account any extensions), then, in the case of clauses (i)
through (iii), the Depositor, the NIM Insurer or the Master Servicer, or in the
case of clause (iv), the Depositor, may remove the Trustee and appoint a
successor trustee, reasonably acceptable to the NIM Insurer, by written
instrument, in triplicate, one copy of which instrument shall be delivered to
the Trustee, one copy of which shall be delivered to the Master Servicer and one
copy of which shall be delivered to the successor trustee.

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

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

                                      149
<PAGE>

            Section 8.08      Successor Trustee.

            Any successor trustee appointed as provided in Section 8.07 hereof
shall execute, acknowledge and deliver to the Depositor, its predecessor trustee
and the Master Servicer an instrument accepting such appointment hereunder and
thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein. In addition, if the Swap Contract is still outstanding,
the Person appointed as successor trustee shall execute, acknowledge and deliver
to the predecessor trustee, CHL and the Master Servicer an instrument accepting
the appointment as successor Swap Contract Administrator under the Swap Contract
Administration Agreement.

            No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer, its appointment shall not adversely affect the
then-current ratings of the Certificates and has provided to the Depositor in
writing and in form and substance reasonably satisfactory to the Depositor, all
information reasonably requested by the Depositor in order to comply with its
reporting obligation under Item 6.02 of Form 8-K with respect to a replacement
Trustee. Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to the NIM Insurer and all Holders of Certificates. If the
Depositor fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Depositor.

            Section 8.09      Merger or Consolidation of Trustee.

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

            As a condition to the effectiveness of any merger or consolidation,
at least 15 calendar days prior to the effective date of any merger or
consolidation of the Trustee, the Trustee shall provide (x) written notice to
the Depositor of any successor pursuant to this Section and (y) in writing and
in form and substance reasonably satisfactory to the Depositor, all information
reasonably requested by the Depositor in order to comply with its reporting
obligation under Item 6.02 of Form 8-K with respect to a replacement Trustee.

            Section 8.10      Appointment of Co-Trustee or Separate Trustee.

            Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust

                                      150
<PAGE>

Fund or property securing any Mortgage Note may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee and reasonably acceptable to the NIM Insurer to act as co-trustee or
co-trustees jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust Fund, and to vest in such Person or Persons, in
such capacity and for the benefit of the Certificateholders, such title to the
Trust Fund or any part thereof, whichever is applicable, and, subject to the
other provisions of this Section 8.10, such powers, duties, obligations, rights
and trusts as the Master Servicer and the Trustee may consider necessary or
desirable. If the Master Servicer shall not have joined in such appointment, or
the NIM Insurer shall not have approved such appointment, within 15 days after
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, the Trustee shall have the power to make such
appointment. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 8.06 and no
notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.08.

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

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

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

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

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

                                      151
<PAGE>

Trustee. Every such instrument shall be filed with the Trustee and a copy
thereof given to the Master Servicer and the Depositor.

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

            Section 8.11      Tax Matters.

            It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC created pursuant
to the Preliminary Statement qualifies as, a "real estate mortgage investment
conduit" as defined in and in accordance with the REMIC Provisions. In
furtherance of such intention, the Trustee covenants and agrees that it shall
act as agent (and the Trustee is hereby appointed to act as agent) on behalf of
the Trust Fund and that in such capacity it shall: (a) prepare and file, or
cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage
Investment Conduit Income Tax Returns (Form 1066 or any successor form adopted
by the Internal Revenue Service) and prepare and file or cause to be prepared
and filed with the Internal Revenue Service and applicable state or local tax
authorities income tax or information returns for each taxable year with respect
to each REMIC created hereunder containing such information and at the times and
in the manner as may be required by the Code or state or local tax laws,
regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty days of the Closing
Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms
8811 or as otherwise may be required by the Code, the name, title, address, and
telephone number of the person that the Holders of the Certificates may contact
for tax information relating thereto, together with such additional information
as may be required by such Form, and update such information at the time or
times in the manner required by the Code for the Trust Fund; (c) make or cause
to be made elections, on behalf of each REMIC created hereunder to be treated as
a REMIC on the federal tax return of each such REMIC for its first taxable year
(and, if necessary, under applicable state law); (d) prepare and forward, or
cause to be prepared and forwarded, to the Certificateholders and to the
Internal Revenue Service and, if necessary, state tax authorities, all
information returns and reports as and when required to be provided to them in
accordance with the REMIC Provisions, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Class A-R Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-through entity in which a Non-Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct the affairs of the Trust Fund at
all times that any Certificates are outstanding so as to maintain the status of
each REMIC created hereunder as a REMIC under the REMIC Provisions; (g) not
knowingly or intentionally take any action or omit to take any action that would
cause the termination of the REMIC status of any REMIC created hereunder; (h)
pay, from the sources specified in the third paragraph of

                                      152
<PAGE>

this Section 8.11, the amount of any federal, state and local taxes, including
prohibited transaction taxes as described below, imposed on any REMIC created
hereunder prior to the termination of the Trust Fund when and as the same shall
be due and payable (but such obligation shall not prevent the Trustee or any
other appropriate Person from contesting any such tax in appropriate proceedings
and shall not prevent the Trustee from withholding payment of such tax, if
permitted by law, pending the outcome of such proceedings); (i) sign or cause to
be signed federal, state or local income tax or information returns; (j)
maintain records relating to each REMIC created hereunder, including but not
limited to the income, expenses, assets and liabilities of each such REMIC, and
the fair market value and adjusted basis of the Trust Fund property determined
at such intervals as may be required by the Code, as may be necessary to prepare
the foregoing returns, schedules, statements or information; and (k) as and when
necessary and appropriate, represent the Trust Fund in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year of
any REMIC created hereunder, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of the Trust Fund, and otherwise act on behalf of any REMIC created
hereunder in relation to any tax matter involving any such REMIC.

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

            In the event that any tax is imposed on "prohibited transactions" of
the Trust Fund as defined in section 860F(a)(2) of the Code, on the "net income
from foreclosure property" of the Trust Fund as defined in section 860G(c) of
the Code, on any contribution to the Trust Fund after the startup day pursuant
to section 860G(d) of the Code, or any other tax is imposed, including, without
limitation, any federal, state or local tax or minimum tax imposed upon the
Trust Fund pursuant to sections 23153 and 24872 of the California Revenue and
Taxation Code if not paid as otherwise provided for herein, such tax shall be
paid by (i) the Trustee, if any such other tax arises out of or results from a
breach by the Trustee of any of its obligations under this Agreement, (ii) (x)
the Master Servicer, in the case of any such minimum tax, and (y) any party
hereto (other than the Trustee) to the extent any such other tax arises out of
or results from a breach by such other party of any of its obligations under
this Agreement or (iii) in all other cases, or in the event that any liable
party here fails to honor its obligations under the preceding clauses (i) or
(ii), any such tax will be paid first with amounts otherwise to be distributed
to the Class A-R Certificateholders, and second with amounts otherwise to be
distributed to all other Certificateholders in the same manner as if such tax
were a Realized Loss that occurred ratably

                                      153
<PAGE>

within each Loan Group. Notwithstanding anything to the contrary contained
herein, to the extent that such tax is payable by the Class A-R Certificates,
the Trustee is hereby authorized to retain on any Distribution Date, from the
Holders of the Class A-R Certificates (and, if necessary, second, from the
Holders of all other Certificates in the priority specified in the preceding
sentence), funds otherwise distributable to such Holders in an amount sufficient
to pay such tax. The Trustee agrees to promptly notify in writing the party
liable for any such tax of the amount thereof and the due date for the payment
thereof.

            The Trustee shall treat the Carryover Reserve Fund and the Swap
Trust, including the Swap Account, as outside reserve funds within the meaning
of Treasury Regulation 1.860G-2(h), neither of which is an asset of any REMIC
created hereunder. The Carryover Reserve Fund shall be treated as owned by the
Class C Certificateholders and the Swap Trust, including the Swap Account, shall
be treated as owned by the Class C Certificateholders. The rights of the Holders
of each Class of Certificates (other than the Class P and Class A-R
Certificates) to receive payments from, and the deemed obligations of such
Holders to make payments to, the Carryover Reserve Fund or the Swap Trust,
including the Swap Account, shall be treated as rights and obligations with
respect to notional principal contracts written by the Holders of the Class C
Certificates in respect of any Net Rate Carryover distributed pursuant to
Sections 4.04(c)(4), and (ii) the Swap Counterparty in respect of any Net Rate
Carryover funded by the Swap Contract and in respect of any residual payments
from such Swap Contract received by the Class C Certificates. Thus, the
Certificates (other than the Class P and Class A-R Certificates), shall be
treated as representing ownership of Master REMIC regular interests coupled with
contractual rights and obligations within the meaning of Treasury Regulation
1.860G-2(i). For purposes of determining the issue price of the various Master
REMIC regular interests, the Trustee shall treat the $1,125,000 upfront amount
received by CHL from the Swap Counterparty in connection with the execution of
the Old Confirmation as an additional amount paid by the Certificateholders for
the Master REMIC regular interests. Any differences in the distributions to a
Certificateholder (positive or negative) that would result from the application
of the Strip REMIC Cap rather than the applicable Net Rate Cap shall be treated
by the Trustee as reconciled among the Certificates by swap payments made
pursuant to notional principal contracts entered into among the
Certificateholders.

            The Trustee shall treat the entitlement to Credit Comeback Excess
Amounts as owned by the Holders of the Class C Certificates and not as an asset
of, or interest in, any REMIC created hereunder. Further, the Trustee shall
treat any payments of Credit Comeback Excess Amounts to Persons other than the
Holders of the Class C Certificates as payments made by the Holders of the Class
C Certificates pursuant to a credit enhancement contract under Treasury
Regulation 1.860G-2(c). The Trustee shall also treat any amount payable to a
Class C Certificate with respect to the STR-C-OC Interest as deposited into the
Carryover Reserve Fund. To the extent the amount payable with respect to the
Swap Contract exceeds the amount payable with respect to the Class C
Certificates, the Trustee, for federal income tax purposes, shall treat such
excess as Realized Losses from Mortgage Loans and to the extent such Realized
Losses (if they had occurred) would be allocated to a Certificateholder, the
Trustee shall treat such amount as first payable to the Certificateholder as
principal and as then payable by the Certificateholder with respect to a
notional principal contract.

                                      154
<PAGE>

            The Trustee shall treat the Final Maturity Reserve Fund as an
outside reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that
is owned by the Holders of the Class C Certificates, and that is not an asset of
any REMIC created hereunder. Beginning on the Distribution Date in December
2016, the Trustee shall treat any monies payable to the Class C
Certificateholders with respect to their interest in the STR-C-40 Year IO, as
first paid to the Class C Certificates and then deposited in the Final Maturity
Reserve Fund. Any monies payable on the STR-C-40 Year IO in excess of the Final
Maturity Required Deposit shall be the "Excess Deposit." For income tax
purposes, to the extent the amount of any Excess Deposit is payable to Holders
of Certificates other than the Class C Certificates, such amount shall be
treated as payable to such Holders as Net Rate Carryover and any remaining
amount of Excess Deposit shall be treated as payable to the Holders of the Class
C Certificates. Any other monies received by the Holders of the Interest-Bearing
Certificates from the Final Maturity Reserve Fund will be treated as monies paid
by the Holders of the Class C Certificates to acquire the Interest-Bearing
Certificates receiving such monies. Thus, with respect to such other monies, the
Interest-Bearing Certificates and the Class C Certificates shall be treated as
representing ownership of not only a Master REMIC regular interest, but also
ownership of an interest in a forward purchase contract and the Trustee shall
treat the rights of the holders of the Interest-Bearing Certificates to receive
such other monies from the Final Maturity Reserve Fund as rights in forward
purchase contracts entered into with the Holders of the Class C Certificates.

            Section 8.12      Co-Trustee.

            (a) The Co-Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Co-Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they conform
to the requirements of this Agreement, to the extent required by this Agreement.
If any such instrument is found not to conform to the requirements of this
Agreement in a material manner, the Co-Trustee shall take action as it deems
appropriate to have the instrument corrected. In addition, the Co-Trustee shall
act as the insured under each Mortgage Insurance Policy and hereby directs the
Master Servicer, on behalf of the Co-Trustee, to take all actions appropriate or
required of the Co-Trustee under each Mortgage Insurance Policy, other than the
payment of each Mortgage Insurance Premium and obtaining the approval of each
Mortgage Insurer with respect to the appointment of a successor servicer.

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

                  (1) the duties and obligations of the Co-Trustee shall be
      determined solely by the express provisions of this Agreement with the
      exception of Section 8.10, the Co-Trustee shall not be liable,
      individually or as Co-Trustee, except for the performance of such duties
      and obligations as are specifically set forth in this Agreement, no
      implied covenants or obligations shall be read into this Agreement against
      the Co-Trustee and the Co-Trustee may conclusively rely, as to the truth
      of the statements and the correctness of the opinions expressed therein,
      upon any certificates or opinions furnished to the Co-

                                      155
<PAGE>

      Trustee and conforming to the requirements of this Agreement that it
      reasonably believed in good faith to be genuine and to have been duly
      executed by the proper authorities respecting any matters arising
      hereunder; and

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

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

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

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

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

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

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

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

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

                                      156
<PAGE>

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

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

            (g) The Co-Trustee hereunder shall, at all times, be a corporation
or association organized and doing business under the laws of a state or the
United States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates below the ratings issued on the
Closing Date (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.12 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately in
the manner and with the effect specified in paragraph (h) below. The corporation
or national banking association serving as Co-Trustee may have normal banking
and trust relationships with the Depositor, the Sellers and the Master Servicer
and their respective affiliates; provided that such corporation

                                      157
<PAGE>

cannot be an affiliate of the Master Servicer other than the Trustee in its role
as successor to the Master Servicer.

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

            Section 8.13      Access to Records of the Trustee.

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

            Section 8.14      Suits for Enforcement.

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

                                   TERMINATION

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

            Subject to Section 9.03 and Section 9.04, the Trust Fund shall
terminate and the obligations and responsibilities of the Depositor, the Master
Servicer, the Sellers, the Trustee and the Co-Trustee created hereby with
respect to the Trust Fund shall terminate upon the earliest of (a) the purchase
by the Master Servicer or NIM Insurer (the party exercising such purchase
option, the "Terminator") of all of the Mortgage Loans (and REO Properties) at a
price (the "Termination Price") equal to the sum of (i) 100% of the Stated
Principal Balance of each Mortgage Loan (other than in respect of an REO
Property), (ii) accrued interest thereon at the applicable Mortgage Rate (or, if
such repurchase is effected by the Master Servicer, at the applicable Net
Mortgage Rate), (iii) the appraised value of any REO Property (up to the Stated
Principal Balance of the related Mortgage Loan), such appraisal to be conducted
by an appraiser mutually agreed upon by the Terminator and the Trustee, (iv) any
remaining unpaid costs and damages incurred by the Trust Fund that arises out of
an actual violation of any predatory or abusive lending law or regulation and
(v) if the Terminator is the NIM Insurer, any unreimbursed Servicing Advances,
and the principal portion of any unreimbursed Advances, made on the Mortgage
Loans prior to the exercise of such repurchase, (b) the purchase by the Winning
Bidder of all of the Mortgage Loans (and REO Properties) after a Successful
Auction is conducted pursuant to Section 9.04 and the related auction proceeds
are distributed pursuant to Section 9.02(c) and (c) the later of (i) the
maturity or other liquidation (or any Advance with respect thereto) of the last
Mortgage Loan remaining in the Trust Fund and the disposition of all REO
Property and (ii) the distribution to the Certificateholders of all amounts
required to be distributed to them pursuant to this Agreement, as applicable. In
no event shall the trusts created hereby continue beyond the earlier of (i) the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late Ambassador of the United States to the Court of St.
James's, living on the date hereof and (ii) the Latest Possible Maturity Date.

            The right to purchase all Mortgage Loans and REO Properties by the
Terminator pursuant to clause (a) of the immediately preceding paragraph shall
be conditioned upon (1) the Stated Principal Balance of the Mortgage Loans, at
the time of any such repurchase, aggregating ten percent (10%) or less of the
sum of the aggregate Cut-off Date Principal Balance of the Initial Mortgage
Loans and the Pre-Funded Amount, (2) unless the NIM Insurer otherwise consents,
the purchase price for such Mortgage Loans and REO Properties shall result in a
final distribution on any NIM Insurer guaranteed notes that is sufficient (x) to
pay such notes in full and (y) to pay any amounts due and payable to the NIM
Insurer pursuant to the indenture related to such notes and (3) the absence of a
request for an auction, or the absence of a Successful Auction, of the Mortgage
Loans and REO Properties pursuant to Section 9.04.

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

                                      159
<PAGE>

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

            Section 9.02      Final Distribution on the Certificates.

            (a) Timing of Notice of Final Distribution, Auction or Optional
Termination.

                  (1) If on any Determination Date, the Master Servicer
      determines that there are no Outstanding Mortgage Loans and no other funds
      or assets in the Trust Fund other than the funds in the Certificate
      Account, then the Master Servicer shall direct the Trustee promptly to
      send a final distribution notice to each Certificateholder in accordance
      with Section 9.02(b). In the event such notice is given, the Master
      Servicer shall cause all funds in the Certificate Account to be remitted
      to the Trustee for deposit in the Distribution Account on or before the
      Business Day prior to the applicable Distribution Date, net of any amounts
      permitted to be withdrawn pursuant to Section 3.08(a). Upon such final
      deposit with respect to the Trust Fund and the receipt by the Trustee of a
      Request for File Release therefor, the Co-Trustee shall promptly release
      to the Master Servicer the Mortgage Files for the Mortgage Loans.

                  (2) If the Directing Certificateholder chooses to exercise its
      right to cause an auction pursuant to Section 9.04, then the Directing
      Certificateholder shall provide written notice to the Master Servicer no
      later than the first day of the calendar month in which such auction is to
      be conducted. If a Successful Auction is held pursuant to the requirements
      of Section 9.04, then the Trustee shall distribute the proceeds of the
      Successful Auction that have been remitted to the Distribution Account to
      the Certificateholders pursuant to Sections 4.04 and 9.04 hereof on the
      Distribution Date in the calendar month immediately following the calendar
      month in which the Successful Auction occurs.

                  (3) If the Directing Certificateholder does not exercise its
      right to cause an auction pursuant to Section 9.04 and the Terminator
      (after prior written notice to the Master Servicer if the Terminator is
      the NIM Insurer) elects to terminate the Trust Fund pursuant to Section
      9.01, then at least 20 days prior to the date notice is to be mailed to
      Certificateholders in accordance with Section 9.02(b), the Terminator
      shall notify the Depositor and the Trustee of (a) its election to
      terminate the Trust Fund, (b) the Distribution Date on which it intends to
      terminate the Trust Fund pursuant to Section 9.01 and (c) the applicable
      purchase price of the Mortgage Loans and REO Properties. In the event such
      notice is given, the Terminator shall remit to the Master Servicer, on or
      before the Business Day prior to the final Distribution Date, for deposit
      into the Certificate Account, the Termination Price. The Master Servicer
      shall cause all funds in the Certificate Account, including the
      Termination Price, net of any amounts permitted to be withdrawn pursuant
      to Section 3.08(a), to be remitted to the Trustee for deposit in the
      Distribution Account on or before the Business Day prior to the applicable
      Distribution Date. Upon such final deposit with respect to the Trust Fund
      and the receipt by the Trustee of a Request for File Release therefor, the
      Co-Trustee shall promptly release to the Master Servicer the Mortgage
      Files for the Mortgage Loans.

                                      160
<PAGE>

            (b) Timing of Notice to Certificateholders of Termination. Notice of
any termination of the Trust Fund (whether because of a Successful Auction,
Optional Termination or otherwise), specifying the Distribution Date on which
Certificateholders may surrender their Certificates for payment of the final
distribution and cancellation, shall be given promptly by the Trustee by letter
to Certificateholders mailed not earlier than the 10th day and no later than the
15th day of the month immediately preceding the month of such final
distribution. Any such notice shall specify (i) the Distribution Date upon which
final distribution on the Certificates will be made upon presentation and
surrender of such Certificates at the office therein designated, (ii) the amount
of such final distribution, (iii) the location of the office or agency at which
such presentation and surrender must be made, and (iv) that the Record Date
otherwise applicable to such Distribution Date is not applicable, distributions
being made only upon presentation and surrender of such Certificates at the
office therein specified. The Master Servicer will give such notice to each
Rating Agency and the Swap Counterparty at the time such notice is given to
Certificateholders.

            (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Certificateholders of each Class, in each
case on the final Distribution Date and in the order and priority set forth in
Section 4.04 (and with respect to the Class C Certificates after a Successful
Auction, Sections 9.04(g) and (k)) hereof and in proportion to their respective
Percentage Interests from the Distribution Account (and, if applicable, the
Carryover Reserve Fund) an amount equal to (i) as to each Class of Regular
Certificates, the Certificate Principal Balance thereof plus accrued interest
thereon (or on its Notional Amount, if applicable) in the case of an
interest-bearing Certificate and (ii) as to the Class A-R Certificates, the
amount, if any, which remains on deposit in the Distribution Account (other than
the amounts retained to meet claims) after application pursuant to clause (i)
above. Notwithstanding the reduction of the Certificate Principal Balance of any
Class of Certificates to zero, such Class will be outstanding hereunder (solely
for the purpose of receiving distributions (if any) to which it may be entitled
pursuant to the terms of this Agreement and not for any other purpose) until the
termination of the respective obligations and responsibilities of the Depositor,
each Seller, the Master Servicer and the Trustee hereunder in accordance with
Article IX.

            (d) In the event that any affected Certificateholders shall not
surrender their respective Certificates for cancellation within six months after
the date specified in the above mentioned written notice, the Trustee shall give
a second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. If within six months after the second notice all the applicable
Certificates shall not have been surrendered for cancellation, the Trustee may
take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining Certificateholders concerning surrender of their
Certificates, and the cost thereof shall be paid out of the funds and other
assets that remain a part of the Trust Fund. If within one year after the second
notice all Certificates shall not have been surrendered for cancellation, the
Class A-R Certificates shall be entitled to all unclaimed funds and other assets
of the Trust Fund that remain subject to this Agreement.

            Section 9.03      Additional Termination Requirements.

            (a) In the event the Terminator exercises its purchase option as
provided in Section 9.01 or there is a Successful Auction pursuant to Section
9.04, the Trust Fund shall be

                                      161
<PAGE>

terminated in accordance with the following additional requirements, unless the
Trustee has been supplied with an Opinion of Counsel, at the expense of the
Terminator (or the Directing Certificateholder, in the case of a Successful
Auction), to the effect that the failure of the Trust Fund to comply with the
requirements of this Section 9.03 will not (i) result in the imposition of taxes
on "prohibited transactions" on any REMIC as defined in Section 860F of the
Code, or (ii) cause any REMIC created hereunder to fail to qualify as a REMIC at
any time that any Certificates are outstanding:

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

                  (2) Within 90 days after the time of adoption of such a plan
      of complete liquidation, the Trustee shall sell all of the assets of the
      Trust Fund to the Terminator (or the Winning Bidder in the case of a
      Successful Auction) for cash in accordance with Section 9.01 and, if
      applicable, Section 9.04.

            (b) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Master Servicer to prepare and the Trustee to adopt and
sign a plan of complete liquidation which authorization shall be binding upon
all successor Certificateholders. The Trustee shall attach a statement to the
final federal income tax return for each of any REMIC created hereunder stating
that pursuant to Treasury Regulation Section 1.860F-1, the first day of the
90-day liquidation period for each the REMIC was the date on which the Trustee
sold the assets of the Trust Fund to the Terminator.

            (c) The Trustee, as agent for any REMIC created hereunder, hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1) and to take such other action in connection
therewith as may be reasonably requested by the Terminator or the Directing
Certificateholder, as applicable.

            Section 9.04      Auction of the Mortgage Loans and REO Properties.

            (a) On or after the Optional Termination Date, the Holder of the
largest Percentage Interest of the Class C Certificates (the "Directing
Certificateholder"), at its option, may by written instruction direct the Master
Servicer to direct the Trustee to solicit bids in a commercially reasonable
manner from Qualified Bidders for the purchase of the Mortgage Loans and any REO
Properties owned by the Trust Fund. The Directing Certificateholder shall
provide written notice to the Master Servicer as provided in Section 9.02(a)(2).
Any such direction by the Directing Certificateholder shall (i) be made in
writing and (ii) include contact information for the Directing
Certificateholder. Upon receipt of any direction from the Directing
Certificateholder meeting the requirements of the immediately preceding
sentence, the Trustee

                                      162
<PAGE>

shall commence the auction process described in this Section 9.04. The Trustee
may engage a financial advisor, which financial advisor may be CHL or one of its
affiliates, in order to perform any of the duties of the Trustee specified in
Section 9.04. To effectuate such sale, the Trustee (or such financial advisor)
shall follow the procedures specified in Section 9.04(b) below. The Trustee
shall facilitate the sale of the assets in the Trust Fund to the Winning Bidder
so long as the Trustee (or any financial advisor on its behalf) has received at
least three bids from Qualified Bidders and at least one such bid is at least
equal to the Acceptable Bid Amount. In the event the auction is not a Successful
Auction, the Trustee may repeat this process periodically thereafter as directed
by the Directing Certificateholder until a Successful Auction is conducted or
the Terminator purchases all of the Mortgage Loans and REO Properties pursuant
to Section 9.01. The Trustee shall be reimbursed for its reasonable costs,
including expenses associated with engaging any financial advisor, from the
Directing Certificateholder if the auction is not a Successful Auction, and, if
the auction is a Successful Auction, from the proceeds of the auction before the
proceeds are distributed to Certificateholders.

            The Trustee, upon inquiry from the Master Servicer, agrees to
provide the Master Servicer with the Percentage Interest of Class C Certificates
held by the Directing Certificateholder.

            If CHL or any of its affiliates is the Directing Certificateholder,
such Directing Certificateholder shall not have the right to direct the Trustee
to solicit bids for the purchase of the Mortgage Loans and any REO Properties
owned by the Trust Fund.

            (b) The Trustee (or any financial advisor on its behalf) shall
      solicit bids for the purchase of assets owned by the Trust Fund as
      provided in Section 9.04(a) not later than two Business Days following
      receipt of the Directing Certificateholder's written instruction by
      contacting by telephone or in writing at least three Qualified Bidders and
      requesting that each Qualified Bidder bid on the Mortgage Loans and REO
      Properties owned by the Trust Fund (on a non-recourse basis with no
      representations or warranties of any nature whatsoever made by the Trustee
      (or such financial advisor)) and providing to the Qualified Bidder any
      information relating to the Mortgage Loans and REO Properties owned by the
      Trust Fund reasonably requested by such Qualified Bidder, subject to the
      Qualified Bidder's written agreement not to use such information in the
      purchase or sale of Certificates (it being understood no Qualified Bidder
      shall be obligated to submit a bid or take any other action in connection
      with any auction). The Master Servicer shall cooperate with the Trustee
      (and any financial advisor on its behalf) during the auction process. At
      1:00 p.m. New York time on the second Business Day after the date on which
      bids are last solicited (such second day, the "Bid Determination Date"),
      the Trustee (or any financial advisor on its behalf) shall determine the
      highest bid based on the bids received by the Trustee (or any financial
      advisor on its behalf) on or before such time.

            (c) If the highest of the bids that are submitted by Qualified
      Bidders are less than the Minimum Auction Amount, then the Trustee shall
      promptly inform the Directing Certificateholder of the amount of the
      shortfall and indicate that the Directing Certificateholder must notify
      the Trustee within 24 hours whether it will contribute the amount of such
      difference (such difference being the "Auction Supplement Amount") so that
      the auction will be a Successful Auction. If the highest of the bids that
      are submitted by Qualified Bidders is equal to or greater than the Minimum
      Auction Amount, or if the Directing Certificateholder notifies the

                                      163
<PAGE>

      Trustee within 24 hours of its receipt of notice as described in the
      previous sentence that it will contribute the Auction Supplement Amount,
      then the Trustee (or any financial advisor on its behalf) shall notify
      promptly (but in any event no later than 3:00 p.m. New York time on the
      Business Day following the Bid Determination Date) the Winning Bidder that
      its bid was the highest bid and shall provide wiring instructions for
      payment of the bid amount into the Certificate Account by 12:00 p.m. New
      York time on the second Business Day following the Bid Determination Date
      and, if applicable, provide the Directing Certificateholder with wiring
      instructions for payment of the Auction Supplement Amount into the
      Certificate Account by such time.

            (d) If such Winning Bidder does not wire the bid amount so that it
      is received in the Certificate Account in immediately available funds by
      12:00 p.m. New York time on the second Business Day following the Bid
      Determination Date, the Trustee shall repeat the process specified in the
      preceding paragraph with respect to the second highest bid, but only if
      such bid is at least the Minimum Auction Amount or the Directing
      Certificateholder agrees to pay the new Auction Supplement Amount. If no
      other bids are available to be accepted pursuant to the preceding
      sentence, or if the amount remitted by the Winning Bidder plus any Auction
      Supplement Amount remitted by the Directing Certificateholder is less than
      the Minimum Auction Amount, then the auction shall be considered to have
      failed for all purposes.

            (e) The Trustee shall not be liable with regard to the selection or
      engagement of, or for any act or omission of, a financial advisor pursuant
      to this Section 9.04 if the Trustee engages CHL to be such financial
      advisor.

            (f) In the event of a Successful Auction and so long as the Winning
      Bidder has wired its bid amount (and the Directing Certificateholder has
      wired any Auction Supplement Amount, if applicable) to the Certificate
      Account as provided above, then the Trustee shall promptly convey to the
      Winning Bidder the Mortgage Loans and REO Properties owned by the Trust
      Fund. The Master Servicer shall take all reasonable actions requested by
      the Trustee to effect such conveyance, including remitting to the
      Distribution Account from the Certificate Account, on the Business Day
      prior to the Distribution Date on which final distribution on the
      Certificates is required to be paid under this Agreement, all amounts on
      deposit in the Certificate Account, net of any amounts permitted to be
      withdrawn pursuant to Section 3.08(a) and amounts owing to the Trustee in
      reimbursement of its reasonable costs, including expenses associated with
      engaging any financial advisor, incurred in connection with the auction
      process. Such amounts owed to the Trustee shall be withdrawn from the
      Certificate Account by the Master Servicer and paid to the Trustee.

            (g) Any amount paid by the Winning Bidder in excess of the Minimum
      Auction Amount shall be distributed by the Trustee pro rata to the Class C
      Certificates on the Distribution Date on which the final distribution on
      the Certificates is made.

            (h) In the event of a Successful Auction and to the extent the Swap
      Contract is still outstanding, the Directing Certificateholder shall
      either:

                                      164
<PAGE>

            (1) if any Swap Termination Payment would be payable by the Swap
      Contract Administrator to the Swap Counterparty were the Swap Contract to
      be terminated following final distribution on the Certificates, either:

            (A) pay to the Swap Contract Administrator any such Swap Termination
      Payment; or

                  (B) accept assignment of the Swap Contract to the extent that
            the Directing Certificateholder is an acceptable counterparty for
            the Swap Counterparty;

            (2) if any Swap Termination Payment would be payable by the Swap
      Counterparty to the Swap Contract Administrator were the Swap Contract to
      be terminated following final distribution on the Certificates, either

                  (A) (i) if the Directing Certificateholder does not own 100%
            of the Class C Certificates, accept assignment of the Swap Contract
            to the extent that the Directing Certificateholder is an acceptable
            counterparty for the Swap Counterparty and pay to the Swap Contract
            Administrator the Swap Termination Payment that would be owed to the
            Swap Contact Administrator by the Swap Counterparty if the Swap
            Contract were terminated by the Swap Contract Administrator
            following distribution on the Certificates or (ii) if the Directing
            Certificateholder owns 100% of the Class C Certificates, accept
            assignment of the Swap Contract to the extent that the Directing
            Certificateholder is an acceptable counterparty for the Swap
            Counterparty; or

                  (B) instruct the Swap Contract Administrator to accept from
            the Swap Counterparty any Swap Termination Payment that would be
            owed to the Swap Contract Administrator.

            (i) Any amounts paid to the Swap Contract Administrator pursuant to
subsection (h)(2) above shall be distributed to the Class C Certificates, pro
rata, based on entitlement, by the Swap Contract Administrator.

            (j) The Master Servicer may purchase the Mortgage Loans and REO
Properties owned by the Trust Fund for its own account pursuant to Section 9.01
or consent to the NIM Insurer's purchase of the Mortgage Loans and REO
Properties owned by the Trust Fund pursuant to Section 9.01 only if (1) the
Directing Certificateholder chooses not to request an auction as described above
or if the immediately preceding auction is unsuccessful or (2) the Master
Servicer notifies the Directing Certificateholder no later than 30 days prior to
the date on which the Master Servicer or the NIM Insurer, as applicable, intends
to effect the purchase of the Mortgage Loans and REO Properties owned by the
Trust Fund and the Directing Certificateholder does not direct the Trustee to
conduct an auction prior to the end of that 30-day period.

            (k) If the Directing Certificateholder pays any Auction Supplement
Amount pursuant to Section 9.04(c) or any Swap Termination Payment pursuant to
Section 9.04(h)(1)(A), on the final Distribution Date any amounts to be
distributed to the Class C Certificates pursuant

                                      165
<PAGE>

to Section 4.02 will be distributed as follows, first to the Directing
Certificateholder, in an amount up to the sum of such Auction Supplement Amount
and such Swap Termination Payment and second to the Class C Certificates, pro
rata. For federal income tax purposes, such Auction Supplement Amount and such
Swap Termination Payment so distributed shall be deemed paid pro rata to the
Class C Certificates, and the portion of such amounts deemed distributed to
holders of the Class C Certificates other than the Directing Certificateholder
shall be deemed paid from such other holders to the Directing Certificateholder.

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

            Section 10.01     Amendment.

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

            The Trustee, the Co-Trustee, the Depositor, the Master Servicer and
the Sellers with the consent of the NIM Insurer may also at any time and from
time to time amend this Agreement, without the consent of the
Certificateholders, to modify, eliminate or add to any of its provisions to such
extent as shall be necessary or appropriate to maintain the qualification of the
Trust Fund as a REMIC under the Code or to avoid or minimize the risk of the
imposition of any tax on the Trust Fund pursuant to the Code that would be a
claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee has been provided an Opinion of Counsel,
which opinion shall be an expense of the party requesting such

                                      166
<PAGE>

opinion but in any case shall not be an expense of the Trustee, to the effect
that such action is necessary or appropriate to maintain such qualification or
to avoid or minimize the risk of the imposition of such a tax.

            This Agreement may also be amended from time to time by the
Depositor, the Master Servicer, the Sellers, the Trustee and the Co-Trustee with
the consent of the NIM Insurer and the Holders of each Class of Certificates
affected thereby evidencing not less than 51% of the Voting Rights of such Class
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided that no such
amendment shall (i) reduce in any manner the amount of, or delay the timing of,
payments required to be distributed on any Certificate without the consent of
the Holder of such Certificate, (ii) adversely affect in any material respect
the interests of the Holders of any Class of Certificates in a manner other than
as described in (i), without the consent of the Holders of Certificates of such
Class evidencing 66% or more of the Voting Rights of such Class, or (iii) reduce
the aforesaid percentages of Certificates the Holders of which are required to
consent to any such amendment without the consent of the Holders of all such
Certificates then outstanding.

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

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

            Promptly after the execution of any amendment to this Agreement, the
Trustee shall furnish written notification of the substance of such amendment to
the Swap Counterparty, to each Certificateholder (if the consent of
Certificateholders is required) and each Rating Agency.

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

            Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel, reasonably satisfactory to
the Trustee and the NIM Insurer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the

                                      167
<PAGE>

amendment does not adversely affect in any material respect the interests of any
Certificateholder or (B) the conclusion set forth in the immediately preceding
clause (A) is not required to be reached pursuant to this Section 10.01.

            Section 10.02     Recordation of Agreement; Counterparts.

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

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

            Section 10.03     Governing Law.

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

            Section 10.04     Intention of Parties.

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

            The Depositor for the benefit of the Certificateholders, the NIM
Insurer and the Swap Counterparty shall, to the extent consistent with this
Agreement, take such actions as may be necessary to ensure that, if this
Agreement were deemed to create a security interest in the assets of the Trust
Fund, such security interest would be deemed to be a perfected security interest
of first priority under applicable law and will be maintained as such throughout
the term

                                      168
<PAGE>

of the Agreement. The Depositor shall arrange for filing any Uniform Commercial
Code continuation statements in connection with any security interest granted or
assigned to the Trustee for the benefit of the Certificateholders and the Swap
Counterparty.

            (b) The Depositor hereby represents that:

                  (i) This Agreement creates a valid and continuing security
            interest (as defined in the Uniform Commercial Code as enacted in
            the State of New York (the "NY UCC")) in the Mortgage Notes in favor
            of the Trustee, which security interest is prior to all other liens,
            and is enforceable as such as against creditors of and purchasers
            from the Depositor.

                  (ii) The Mortgage Notes constitute "instruments" within the
            meaning of the NY UCC.

                  (iii) Immediately prior to the assignment of each Mortgage
            Loan to the Trustee, the Depositor owns and has good and marketable
            title to such Mortgage Loan free and clear of any lien, claim or
            encumbrance of any Person.

                  (iv) The Depositor has received all consents and approvals
            required by the terms of the Mortgage Loans to the sale of the
            Mortgage Loans hereunder to the Trustee.

                  (v) All original executed copies of each Mortgage Note that
            are required to be delivered to the Co-Trustee pursuant to Section
            2.01 have been delivered to the Co-Trustee.

                  (vi) Other than the security interest granted to the Trustee
            pursuant to this Agreement, the Depositor has not pledged, assigned,
            sold, granted a security interest in, or otherwise conveyed any of
            the Mortgage Loans. The Depositor has not authorized the filing of
            and is not aware of any financing statements against the Depositor
            that include a description of collateral covering the Mortgage Loans
            other than any financing statement relating to the security interest
            granted to the Trustee hereunder or that has been terminated. The
            Depositor is not aware of any judgment or tax lien filings against
            the Depositor.

            (c) The Master Servicer shall take such action as is reasonably
necessary to maintain the perfection and priority of the security interest of
the Trustee in the Mortgage Loans; provided, however, that the obligation to
deliver the Mortgage File to the Co-Trustee pursuant to Section 2.01 shall be
solely the Depositor's obligation and the Master Servicer shall not be
responsible for the safekeeping of the Mortgage Files by the Co-Trustee.

            (d) It is understood and agreed that the representations and
warranties set forth in subsection (b) above shall survive delivery of the
Mortgage Files to the Co-Trustee. Upon discovery by the Depositor or the Trustee
of a breach of any of the foregoing representations and warranties set forth in
subsection (b) above, 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.

Agreement or of the Certificates or the rights of the Holders thereof.

            Section 10.07     Assignment.

            Notwithstanding anything to the contrary contained herein, except as

Depositor.

            Section 10.08     Limitation on Rights of Certificateholders.

            The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or the Trust Fund, nor entitle such

take any action or commence any proceeding in any court for a petition or
winding up of the Trust Fund, or otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

            No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and management
of the Trust Fund, or the obligations of the parties hereto, nor shall anything
herein set forth or contained in the terms of the Certificates be construed so
as to constitute the Certificateholders from time to time as partners or members
of an association; nor shall any Certificateholder be under any liability to any
third party by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

            No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as hereinbefore

                                      171

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

            Section 10.09     Inspection and Audit Rights.

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

            Section 10.10     Certificates Nonassessable and Fully Paid.

            It is the intention of the Depositor that Certificateholders shall
not be personally liable for obligations of the Trust Fund, that the interests
in the Trust Fund represented by the Certificates shall be nonassessable for any
reason whatsoever, and that the Certificates, upon due authentication thereof by
the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

            Section 10.11     Rights of NIM Insurer.

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

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

                                      172
<PAGE>

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

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

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

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

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

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

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

            The Master Servicer, the Trustee and each Seller shall reasonably
cooperate with the Depositor in connection with the satisfaction of the
Depositor's reporting requirements under the Exchange Act with respect to the

the Depositor for the purpose of satisfying its reporting obligation under the
Exchange Act, the Master Servicer, the Trustee and each Seller shall (and the
Master Servicer shall cause each Subservicer to) provide the Depositor with (a)
such information which is available to such Person without unreasonable effort
or expense and within such timeframe as may be reasonably requested by the
Depositor to comply with the Depositor's reporting obligations under the
Exchange Act and (b) to the extent such Person is a party (and the Depositor is
not a party) to any agreement or amendment required to be filed, copies of such
agreement or amendment in EDGAR-compatible form.

            Section 11.02     Form 10-D Filings.

            (a) In accordance with the Exchange Act, the Trustee shall prepare
for filing and file within 15 days after each Distribution Date (subject to
permitted extensions under the Exchange Act) with the Commission with respect to
the Trust Fund, a Form 10-D with copies of the Monthly Statement and, to the
extent delivered to the Trustee, no later than 10 days following the
Distribution Date, such other information identified by the Depositor or the
Master Servicer, in writing, to be filed with the Commission (such other
information, the "Additional Designated Information"). If the Depositor or
Master Servicer directs that any Additional Designated Information is to be
filed with any Form 10-D, the Depositor or Master Servicer, as the case may be,
shall specify the Item on Form 10-D to which such information is responsive and,
with respect to any Exhibit to be filed on Form 10-D, the Exhibit number. Any
information to be filed on Form 10-D shall be delivered to the Trustee in
EDGAR-compatible form or as otherwise agreed upon by the Trustee and the
Depositor or the Master Servicer, as the case may be, at the Depositor's
expense, and any necessary conversion to EDGAR-compatible format will be at the
Depositor's expense. At the reasonable request of, and in accordance with the
reasonable directions of, the Depositor or the Master Servicer, subject to the
two preceding sentences, the Trustee shall prepare for filing and file an
amendment to any Form 10-D previously filed with the Commission with respect to
the Trust Fund. The Master Servicer shall sign the Form 10-D filed on behalf of
the Trust Fund.

            (b) No later than each Distribution Date, each of the Master
Servicer and the Trustee shall notify (and the Master Servicer shall cause any
Subservicer to notify) the Depositor and the Master Servicer of any Form 10-D
Disclosure Item, together with a description of any such Form 10-D Disclosure
Item in form and substance reasonably acceptable to the Depositor. In addition
to such information as the Master Servicer and the Trustee are obligated to
provide pursuant to other provisions of this Agreement, if so requested by the
Depositor, each of the Master Servicer and the Trustee shall provide such
information which is available to the Master Servicer and the Trustee, as
applicable, without unreasonable effort or expense regarding the performance or
servicing of the Mortgage Loans (in the case of the Trustee, based on the

                                      174
<PAGE>

information provided by the Master Servicer) as is reasonably required to
facilitate preparation of distribution reports in accordance with Item 1121 of
Regulation AB. Such information shall be provided concurrently with the
Remittance Reports in the case of the Master Servicer and the Monthly Statement
in the case of the Trustee, commencing with the first such report due not less
than five Business Days following such request.

            (c) The Trustee shall not have any responsibility to file any items
(other than those generated by it) that have not been received in a format
suitable (or readily convertible into a format suitable) for electronic filing
via the EDGAR system and shall not have any responsibility to convert any such
items to such format (other than those items generated by it or that are readily
convertible to such format). The Trustee shall have no liability to the
Certificateholders, the Trust Fund, the Master Servicer, the Depositor or the
NIM Insurer with respect to any failure to properly prepare or file any of Form
10-D to the extent that such failure is not the result of any negligence, bad
faith or willful misconduct on its part.

            Section 11.03     Form 8-K Filings.

            The Master Servicer shall prepare and file on behalf of the Trust
Fund any Form 8-K required by the Exchange Act. Each Form 8-K must be signed by
the Master Servicer. Each of the Master Servicer (and the Master Servicer shall
cause any Subservicer to promptly notify) and the Trustee shall promptly notify
the Depositor and the Master Servicer (if the notifying party is not the Master
Servicer), but in no event later than one (1) Business Day after its occurrence,
of any Reportable Event of which it has actual knowledge. Each Person shall be
deemed to have actual knowledge of any such event to the extent that it relates
to such Person or any action or failure to act by such Person. Concurrently with
any Subsequent Transfer, CHL shall notify the Depositor and the Master Servicer,
if any material pool characteristic of the actual asset pool at the time of
issuance of the Certificates differs by 5% or more (other than as a result of
the pool assets converting into cash in accordance with their terms) from the
description of the asset pool in the Prospectus Supplement.

            Section 11.04     Form 10-K Filings.

            Prior to March 30th of each year, commencing in 2007 (or such
earlier date as may be required by the Exchange Act), the Depositor shall

as required by the Exchange Act. A senior officer in charge of the servicing
function of the Master Servicer shall sign each Form 10-K filed on behalf of the
Trust Fund. Such Form 10-K shall include as exhibits each (i) annual compliance
statement described under Section 3.17, (ii) annual report on assessments of
compliance with servicing criteria described under Section 11.07 and (iii)
accountant's report described under Section 11.07. Each Form 10-K shall also
include any Sarbanes-Oxley Certification required to be included therewith, as
described in Section 11.05.

            If the Item 1119 Parties listed on Exhibit Z have changed since the
Closing Date, no later than March 1 of each year, the Master Servicer shall
provide each of the Master Servicer (and the Master Servicer shall provide any
Subservicer) and the Trustee with an updated Exhibit Z setting forth the Item
1119 Parties. No later than March 15 of each year, commencing in 2007, the
Master Servicer and the Trustee shall notify (and the Master Servicer shall
cause any

                                      175
<PAGE>

Subservicer to notify) the Depositor and the Master Servicer of any Form 10-K
Disclosure Item, together with a description of any such Form 10-K Disclosure
Item in form and substance reasonably acceptable to the Depositor. Additionally,
each of the Master Servicer and the Trustee shall provide, and shall cause each
Reporting Subcontractor retained by the Master Servicer or the Trustee, as
applicable, and in the case of the Master Servicer shall cause each Subservicer,
to provide, the following information no later than March 15 of each year in
which a Form 10-K is required to be filed on behalf of the Trust Fund: (i) if
such Person's report on assessment of compliance with servicing criteria
described under Section 11.07 or related registered public accounting firm
attestation report described under Section 11.07 identifies any material
instance of noncompliance, notification of such instance of noncompliance and
(ii) if any such Person's report on assessment of compliance with servicing
criteria or related registered public accounting firm attestation report is not
provided to be filed as an exhibit to such Form 10-K, information detailing the
explanation why such report is not included.

            Section 11.05     Sarbanes-Oxley Certification.

            Each Form 10-K shall include a certification (the "Sarbanes-Oxley
Certification") required by Rules 13a-14(d) and 15d-14(d) under the Exchange Act
(pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 and the rules and
regulations of the Commission promulgated thereunder (including any
interpretations thereof by the Commission's staff)). No later than March 15 of
each year, beginning in 2007, the Master Servicer and the Trustee shall (unless
such person is the Certifying Person), and the Master Servicer shall cause each
Subservicer and each Reporting Subcontractor and the Trustee shall cause each
Reporting Subcontractor to, provide to the Person who signs the Sarbanes-Oxley
Certification (the "Certifying Person") a certification (each, a "Performance
Certification"), in the form attached hereto as Exhibit X-1 (in the case of a
Subservicer or any Reporting Subcontractor of the Master Servicer or a
Subservicer) and Exhibit X-2 (in the case of the Trustee or any Reporting
Subcontractor of the Trustee), on which the Certifying Person, the entity for
which the Certifying Person acts as an officer, and such entity's officers,
directors and Affiliates (collectively with the Certifying Person,
"Certification Parties") can reasonably rely. The senior officer in charge of
the servicing function of the Master Servicer shall serve as the Certifying
Person on behalf of the Trust Fund. Neither the Master Servicer nor the
Depositor will request delivery of a certification under this clause unless the
Depositor is required under the Exchange Act to file an annual report on Form
10-K with respect to the Trust Fund. In the event that prior to the filing date
of the Form 10-K in March of each year, the Trustee or the Depositor has actual
knowledge of information material to the Sarbanes-Oxley Certification, the
Trustee or the Depositor, as the case may be, shall promptly notify the Master
Servicer and the Depositor. The respective parties hereto agree to cooperate
with all reasonable requests made by any Certifying Person or Certification
Party in connection with such Person's attempt to conduct any due diligence that
such Person reasonably believes to be appropriate in order to allow it to
deliver any Sarbanes-Oxley Certification or portion thereof with respect to the
Trust Fund.

            Section 11.06     Form 15 Filing.

            Prior to January 30 of the first year in which the Depositor is able
to do so under applicable law, the Depositor shall file a Form 15 relating to
the automatic suspension of reporting in respect of the Trust Fund under the
Exchange Act.

            Section 11.07     Report on Assessment of Compliance and
                              Attestation.

            (a) On or before March 15 of each calendar year, commencing in 2007:

                  (1) Each of the Master Servicer and the Trustee shall deliver
      to the Depositor and the Master Servicer a report (in form and substance
      reasonably satisfactory to the Depositor) regarding the Master Servicer's
      or the Trustee's, as applicable, assessment of compliance with the
      Servicing Criteria during the immediately preceding calendar year, as
      required under Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122
      of Regulation AB. Such report shall be signed by an authorized officer of
      such Person and shall address each of the Servicing Criteria specified on
      a certification substantially in the form of Exhibit Y hereto delivered to
      the Depositor concurrently with the execution of this Agreement. To the
      extent any of the Servicing Criteria are not applicable to such Person,
      with respect to asset-backed securities transactions taken as a whole
      involving such Person and that are backed by the same asset type backing
      the Certificates, such report shall include such a statement to that
      effect. The Depositor and the Master Servicer, and each of their
      respective officers and directors shall be entitled to rely on upon each
      such servicing criteria assessment.

                  (2) Each of the Master Servicer and the Trustee shall deliver
      to the Depositor and the Master Servicer a report of a registered public
      accounting firm reasonably acceptable to the Depositor that attests to,
      and reports on, the assessment of compliance made by Master Servicer or
      the Trustee, as applicable, and delivered pursuant to the preceding
      paragraphs. Such attestation shall be in accordance with Rules
      1-02(a)(3)and 2-02(g) of Regulation S-X under the Securities Act and the
      Exchange Act, including, without limitation that in the event that an
      overall opinion cannot be expressed, such registered public accounting
      firm shall state in such report why it was unable to express such an
      opinion. Such report must be available for general use and not contain
      restricted use language. To the extent any of the Servicing Criteria are
      not applicable to such Person, with respect to asset-backed securities
      transactions taken as a whole involving such Person and that are backed by
      the same asset type backing the Certificates, such report shall include
      such a statement that that effect.

                  (3) The Master Servicer shall cause each Subservicer and each
      Reporting Subcontractor to deliver to the Depositor an assessment of
      compliance and accountant's attestation as and when provided in paragraphs
      (a) and (b) of this Section 11.07.

                  (4) The Trustee shall cause each Reporting Subcontractor to
      deliver to the Depositor and the Master Servicer an assessment of
      compliance and accountant's attestation as and when provided in paragraphs
      (a) and (b) of this Section.

                  (5) The Master Servicer and the Trustee shall execute (and the
      Master Servicer shall cause each Subservicer to execute, and the Master
      Servicer and the Trustee shall cause each Reporting Subcontractor to
      execute) a reliance certificate to enable the Certification Parties to
      rely upon each (i) annual compliance statement provided pursuant to
      Section 3.17, (ii) annual report on assessments of compliance with
      servicing criteria

                                      177
<PAGE>

      provided pursuant to this Section 11.07 and (iii) accountant's report
      provided pursuant to this Section 11.07 and shall include a certification
      that each such annual compliance statement or report discloses any
      deficiencies or defaults described to the registered public accountants of
      such Person to enable such accountants to render the certificates provided
      for in this Section 11.07.

            (b) In the event the Master Servicer, any Subservicer, the Trustee
or Reporting Subcontractor is terminated or resigns during the term of this
Agreement, such Person shall provide documents and information required by this
Section 11.07 with respect to the period of time it was subject to this
Agreement or provided services with respect to the Trust Fund, the Certificates
or the Mortgage Loans.

            (c) Each assessment of compliance provided by a Subservicer pursuant
to Section 11.07(a)(3)shall address each of the Servicing Criteria specified on
a certification substantially in the form of Exhibit Y hereto delivered to the
Depositor concurrently with the execution of this Agreement or, in the case of a
Subservicer subsequently appointed as such, on or prior to the date of such
appointment. An assessment of compliance provided by a Subcontractor pursuant to
Section 11.07(a)(3)or (4) need not address any elements of the Servicing
Criteria other than those specified by the Master Servicer or the Trustee, as
applicable, pursuant to Section 11.07(a)(1).

            Section 11.08     Use of Subservicers and Subcontractors.

            (a) The Master Servicer shall cause any Subservicer used by the
Master Servicer (or by any Subservicer) for the benefit of the Depositor to
comply with the provisions of Section 3.17 and this Article XI to the same
extent as if such Subservicer were the Master Servicer (except with respect to
the Master Servicer's duties with respect to preparing and filing any Exchange
Act Reports or as the Certifying Person). The Master Servicer shall be
responsible for obtaining from each Subservicer and delivering to the Depositor
any servicer compliance statement required to be delivered by such Subservicer
under Section 3.17, any assessment of compliance and attestation required to be
delivered by such Subservicer under Section 11.07 and any certification required
to be delivered to the Certifying Person under Section 11.05 as and when
required to be delivered. As a condition to the succession to any Subservicer as
subservicer under this Agreement by any Person (i) into which such Subservicer
may be merged or consolidated, or (ii) which may be appointed as a successor to
any Subservicer, the Master Servicer shall provide to the Depositor, at least 15
calendar days prior to the effective date of such succession or appointment, (x)
written notice to the Depositor of such succession or appointment and (y) in
writing and in form and substance reasonably satisfactory to the Depositor, all
information reasonably requested by the Depositor in order to comply with its
reporting obligation under Item 6.02 of Form 8-K.

            (b) It shall not be necessary for the Master Servicer, any
Subservicer or the Trustee to seek the consent of the Depositor or any other
party hereto prior to the utilization of any Subcontractor. The Master Servicer
or the Trustee, as applicable, shall promptly upon request provide to the
Depositor (or any designee of the Depositor, such as the Master Servicer or
administrator) a written description (in form and substance satisfactory to the
Depositor) of the role and function of each Subcontractor utilized by such
Person (or in the case of the Master

                                      178
<PAGE>

Servicer, any Subservicer), specifying (i) the identity of each such
Subcontractor, (ii) which (if any) of such Subcontractors are "participating in
the servicing function" within the meaning of Item 1122 of Regulation AB, and
(iii) which elements of the Servicing Criteria will be addressed in assessments
of compliance provided by each Subcontractor identified pursuant to clause (ii)
of this paragraph.

            As a condition to the utilization of any Subcontractor determined to
be a Reporting Subcontractor, the Master Servicer or the Trustee, as applicable,
shall cause any such Subcontractor used by such Person (or in the case of the
Master Servicer, any Subservicer) for the benefit of the Depositor to comply
with the provisions of Sections 11.07 and 11.09 of this Agreement to the same
extent as if such Subcontractor were the Master Servicer (except with respect to
the Master Servicer's duties with respect to preparing and filing any Exchange
Act Reports or as the Certifying Person) or the Trustee, as applicable. The
Master Servicer or the Trustee, as applicable, shall be responsible for
obtaining from each Subcontractor and delivering to the Depositor and the Master
Servicer, any assessment of compliance and attestation required to be delivered
by such Subcontractor under Section 11.05 and Section 11.07, in each case as and
when required to be delivered.

            Section 11.09     Amendments.

            In the event the parties to this Agreement desire to further clarify
or amend any provision of this Article XI, this Agreement shall be amended to
reflect the new agreement between the parties covering matters in this Article
XI pursuant to Section 10.01, which amendment shall not require any Opinion of
Counsel or Rating Agency confirmations or the consent of any Certificateholder
or the NIM Insurer.

            If, during the period that the Depositor is required to file
Exchange Act Reports with respect to the Trust Fund, the Master Servicer is no
longer an Affiliate of the Depositor, the Depositor shall assume the obligations
and responsibilities of the Master Servicer in this Article XI with respect to
the preparation and filing of the Exchange Act Reports and/or acting as the
Certifying Person, if the Depositor has received indemnity from such successor
Master Servicer satisfactory to the Depositor, and such Master Servicer has
agreed to provide a Sarbanes-Oxley Certification to the Depositor substantially
in the form of Exhibit AA and the certifications referred to in Section 11.07.

            Section 11.10     Reconciliation of Accounts.

            Any reconciliation of Accounts performed by any party hereto, or any

Gentlemen:

            In accordance with Section 2.02 of the Pooling and Servicing
Agreement dated as of November 1, 2006 (the "Pooling and Servicing Agreement")
among CWABS, Inc., as Depositor, Countrywide Home Loans, Inc., as a Seller, Park

Servicing LP, as Master Servicer, the undersigned, as Trustee, and The Bank of
New York Trust Company, N.A., as Co-Trustee, the undersigned, as Trustee, hereby
certifies that, as to each Mortgage Loan listed in the Mortgage Loan Schedule
(other than any Mortgage Loan paid in full or listed in the attached list of
exceptions) the Co-Trustee has received:

            (i) the original Mortgage Note, endorsed by manual or facsimile
signature in blank in the following form: "Pay to the order of ______________,
without recourse", 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

            (ii) a duly executed assignment of the Mortgage or a copy of such
assignment, in either case in the form permitted by Section 2.01 of the Pooling
and Servicing Agreement.

            Based on its review and examination and only as to the foregoing
documents, such documents appear regular on their face and related to such
Mortgage Loan.

            The Trustee has made no independent examination of any documents
contained in each Mortgage File beyond the review specifically required in the
Pooling and Servicing Agreement. The Trustee makes no representations as to: (i)
the validity, legality, sufficiency, enforceability or genuineness of any of the
documents contained in each Mortgage File of any of the Mortgage Loans
identified on the Mortgage Loan Schedule or (ii) the collectibility,
insurability, effectiveness or suitability of any such Mortgage Loan.

                        )     ss.:
COUNTY OF               )

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

            1. The undersigned is an officer of _______________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, dated as
of November 1, 2006 (the "Agreement"), by and among CWABS, Inc., as depositor
(the "Depositor"), Countrywide Home Loans, Inc., as a Seller, Park Monaco Inc.,
as a Seller, Park Sienna LLC, as a Seller, Countrywide Home Loans Servicing LP,
as Master Servicer, The Bank of New York, as Trustee, and The Bank of New York
Trust Company, N.A., as Co-Trustee. Capitalized terms used, but not defined
herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in
the Agreement. The Transferee has authorized the undersigned to make this
affidavit on behalf of the Transferee.

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

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

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

                                      I-1
<PAGE>

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

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

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

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

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

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

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

                               Certain Definitions

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

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

qualify as a REMIC at any time that any Certificates are Outstanding. The terms
"United States," "State" and "International Organization" shall have the
meanings set forth in section 7701 of the Code or successor provisions. A

                        Section 5.02(c) of the Agreement

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

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

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

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

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

                                      I-5
<PAGE>

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

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

with respect to such Principal Prepayment was or was not, as indicated on the

which all or part of the Prepayment Charge required in connection with the

indicated on the attached schedule, based upon:

                  (i) the Master Servicer's determination that such waiver would

            bankruptcy, insolvency, moratorium, receivership, or other similar
            law relating to creditors' rights generally or (2) due to

            payment, or (B) the enforceability is otherwise limited or
            prohibited by applicable law; and

            4. We certify that all amounts due in connection with the waiver of

GOLD RUN INC.

COMMON STOCK PURCHASE WARRANT

FOR VALUE RECEIVED, Gold Run Inc.,
a Delaware corporation (the “Company”) hereby grants to ________________ (together with such
person’s successors and assigns, the “Holder”) the right to purchase at any time commencing as
of the date hereof and ending on ________________ (the “Expiration Date”) up to
________________ of fully paid and non-assessable shares of the Company’s common stock, par value
$.000001 per share (the “Common Stock”) for a purchase price of One Dollar ($1.00) per share.

The Holder agrees that this
Warrant is issued and all rights hereunder shall be held subject to all of the terms, conditions, limitations
and provisions set forth herein.

Section 1. Exercise of Warrant

This Warrant may be exercised in
whole or in part at any time in the Holder’s sole discretion until the Expiration Date at 11:59:59 PM,
Eastern Standard Time.

1.1.
Exercise in Whole or in Part. The Holder may exercise this Warrant in whole or in part by delivering a
duly executed original of the Exercise Form, the form of which is annexed hereto, together with this Warrant,
to the Company at its principal office, accompanied by payment, in cash, wire transfer or by certified
official bank check payable to the order of the Company, in the amount of the product obtained by multiplying
(a) the number of shares for which this Warrant is being exercised as indicated on the Exercise Form, times
(b) the “Warrant Price” (as defined in Section 2) that is then in effect. In the event of a partial
exercise of this Warrant, the Company shall at its sole expense issue and

	

deliver to the Holder a replacement Warrant of
like tenor subject to the provisions of Section 4.4 below.

1.2
Delivery upon Exercise. The Company agrees that the shares of Common
Stock purchased upon the exercise of this Warrant shall be deemed to have been
issued to the Holder as of date on which this Warrant shall have been
surrendered and payment for such shares shall have been made pursuant to Section
1.1 above. As soon as practicable after the exercise of any portion of this
Warrant, but in no event more than ten (10) business days thereafter, the
Company shall at its sole expense (which shall include the payment of any
applicable taxes) cause the Holder to be issued a certificate for that number of
Warrant Shares for which this Warrant or any portion thereof shall have been
exercised.

Section 2. Initial Warrant
Shares and Warrant Price; Adjustment

2.1
Initial Warrant Shares and Price. This Warrant shall initially be
exercisable for ________________ shares of the Company’s Common
Stock (the “Warrant Shares”). The purchase price for the Warrant
Shares shall initially be One Dollar ($1.00) per share (the “Warrant
Price”). The number of Warrant Shares and the Warrant Price shall from time
to time be adjusted as set forth in Section 2.2 below.

2.2
Anti-Dilution Protection.

2.2.1
Adjustment for Reorganization, Consolidation, Merger, etc. In the event
that the Company shall (i) effect a reorganization, (ii) consolidate
with or merge into any other entity or (iii) transfer all or substantially
all of its properties or assets to any other entity under any plan or
arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition precedent to the consummation of such a transaction, proper
and adequate provision shall be made whereby the Holder of this Warrant, on the
exercise hereof as provided in Section 1 above, at any time after the
consummation of any such reorganization, consolidation or merger or the
effective date of any such dissolution, shall receive in lieu of the Warrant
Shares issuable on such exercise prior to any such consummation or effective
date, the stock and other securities and property (including cash) to which such
Holder would have been entitled to receive upon any such consummation or
dissolution if the Holder had so exercised this Warrant immediately prior
thereto.

2.2.2
Adjustment for Dividends, Splits, Reverse Splits. In the event that the
Company shall (a) issue additional shares of Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its
outstanding shares of Common Stock, or (c) combine its outstanding shares
of Common Stock into a smaller number of shares of Common Stock, then, in any
such event, the Warrant Price shall simultaneously with the occurrence thereof
be adjusted to equal the product obtained by multiplying (i) the Warrant Price
in effect immediately prior to any such event times (ii) a fraction, the

	-2-
	

numerator of which shall be
(iii) the number of shares of Common Stock outstanding immediately prior to any such
event, and the denominator of which shall be (iv) the number of shares of Common Stock
outstanding immediately after such event. The number of Warrant Shares that the Holder may
exercise after any such event shall simultaneously with the occurrence of any such event
be adjusted to equal the product obtained by multiplying (v) the number of Warrant Shares
that would otherwise be issuable upon such exercise, times (vi) a fraction, the numerator
of which shall be (vii) the Warrant Price in effect immediately prior to any such event,
and the denominator of which shall be (viii) the Warrant Price in effect as of the date of
any such exercise.

2.2.3
Delivery to Holder. In the event that any occurrence set forth in
Sections 2.2.1 and 2.2.2 above shall take place, then the Company shall at its
sole expense expeditiously cause the Holder to be delivered the stock and other
securities and property (including cash, where applicable) to which it would be
entitled pursuant to Sections 2.2.1 and 2.2.2 above.

2.3
Certificate as to Adjustments. The computation of any adjustment as to
the number of Warrant Shares or the Warrant Price described in Section 2.2 above
shall be the sole responsibility of The Company, which shall expeditiously
prepare and mail to the Holder a notice setting forth the nature of any
necessary adjustment together with the basis thereof and the calculations
therefor. The Company shall immediately notify the Holder of any information
which bears on any of the events referenced in Section 2.2 above and which may
have an effect on the Warrant Price or number of Warrant Shares for which this
Warrant is exercisable.

2.4
Fractional Interests. No fractional shares or scrip representing
fractional shares shall be issuable upon the exercise of this Warrant. Upon the
exercise of this Warrant or any portion thereof, the Holder may purchase only a
whole number of shares of Common Stock. If, upon exercise of this Warrant, the
Holder would be entitled to a fractional share of Common Stock or a right to
acquire a fractional share of Common Stock, then such fractional share shall be
disregarded and the number of shares of Common Stock issuable upon exercise
shall be rounded to the next higher number of shares.

Section 3. Transfer of
Warrant or Warrant Shares

3.1
Limitations on Transfer. Neither this Warrant nor the Warrant Shares
issuable hereunder may be sold or transferred until ________________,
which is one (1) year after the Company’s registration statement for its
shares of Common Stock and this Warrant was declared effective.

3.2
Exempted Transfers. Notwithstanding the foregoing, the following
transfers are permitted at any time: a transfer by a Holder that is a
corporation to another corporation

	-3-
	

that is a wholly-owned
subsidiary of such Holder; a transfer by a Holder that is a partnership to a partner of
such partnership or a retired partner of such partnership or to the estate of any such
partner or retired partner; or a transfer by a Holder that is a limited liability company
to a member of such limited liability company or a retired member or to the estate of any
such member or retired member, provided that the transferee in each case agrees in writing
to be subject to the terms of this Section 3.

3.3
Notification of Transfer. The Holder shall promptly notify the Company of
the name, telephone and facsimile numbers of any person(s) to whom the Holder
shall transfer this Warrant.

3.4
Legend. This Warrant and each certificate representing the Warrant Shares
shall bear a legend substantially in the form set forth at the head of this
Warrant.

Section 4. Miscellaneous

4.1
No Impairment. The Company shall not, by amendment of its charter or
through reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or through any other voluntary action, avoid or seek
to avoid the observance or performance of any of the terms of this Warrant, but
shall at all times and in good faith assist in the carrying out of all such
terms and in the taking of all such action as may be necessary or appropriate in
order to protect the rights of the Holder against impairment.

4.3
Exchange of Warrant. Upon the surrender of this Warrant by the Holder to
the Company at its principal office, the Company will issue and deliver to such
Holder, at the Company’s expense, a new Warrant of like tenor in the name
of the Holder, calling on the face thereof for the number of Warrant Shares or
other securities, cash and/or property then issuable upon the exercise of this
Warrant.

4.4
Replacement of Warrant. Upon receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant and
(in the case of loss, theft or destruction) upon delivery of an indemnity
agreement (without obligation for a surety or other security therefor) in an
amount reasonably satisfactory to the Company, or (in the case of mutilation)
upon surrender and cancellation of this Warrant, the Company will issue, in lieu
thereof and at its sole expense, a new Warrant of like tenor. In the event that
the Holder shall elect to exercise this Warrant in part, then the Company will
at its sole expense issue to the Holder a replacement Warrant of like tenor,
wherein the initial number

	-4-
	

of Warrant Shares for such
replacement Warrant shall be equal to the difference, rounded up to the nearest whole
integer, of (i) the number of Warrant Shares for which this Warrant was exercisable
immediately prior to its partial exercise, minus (ii) the number of Warrant Shares for
which this Warrant was partially exercised.
