            POOLING AND SERVICING AGREEMENT, dated as of July 1, 2006, by and
among CWABS, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC., a New York corporation, as seller ("CHL" or a
"Seller"), PARK MONACO INC., a Delaware corporation, as a seller ("Park
Monaco" or a "Seller"), PARK SIENNA LLC, a Delaware limited liability company,
as a seller ("Park Sienna" or a "Seller", and together with CHL and Park
Monaco, the "Sellers"), COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited
partnership, as master servicer (the "Master Servicer"), 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
Final Maturity Reserve Trust, the Fixed Rate Final Maturity Reserve Fund, the
Adjustable Rate Final Maturity Reserve Fund, the Swap Trust, the Swap Contract
or the Swap Account.

            SWAP-IO REMIC:

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

(1)   On the Closing Date and on each Distribution Date, following the
      allocation of Principal Amounts and Realized Losses in respect of the
      Group 1 Mortgage Loans, the principal balance in respect of the Class
      SWR-F1 Interest will equal the sum of (a) the principal balance of the
      Group 1 Mortgage Loans (as of the end of the related Due Period, reduced
      by principal prepayments received after the Due Period that are to be
      distributed on the Distribution Date related to the Due Period) and (b)
      the amount, if any, on deposit in the Pre-Funding Account in respect of
      Loan Group 1.

(2)   A rate equal to the Loan Group 1 Net Rate Cap. The "Loan Group 1 Net
      Rate Cap" means the weighted average of the Adjusted Net Mortgage Rates
      of all the Mortgage Loans in Loan Group 1. For purposes of this
      definition, beginning on the Distribution Date in August 2016 and ending
      on the Distribution Date in January 2037, the Adjusted Net


                                      4

      Mortgage Rate shall be determined by first reducing the interest payable
      on each Group 1 Mortgage Loan by the 40-Year Fixed Reserve Rate (as
      defined below).

(3)   On each Distribution Date the Class SWR-PF Interest is entitled to all
      Prepayment Charges collected with respect to the Fixed Rate Mortgage
      Loans. It pays no interest.

(4)   Beginning on the Distribution Date in August 2016 and ending on the
      Distribution Date in January 2037, the SWR-F-40 Year Reserve Interest
      shall be entitled to a specified portion of the interest payable on each
      Group 1 Mortgage Loan. Specifically, the SWR-F-40 Year Reserve Interest
      shall be entitled to a specified portion of the interest payable on the
      Stated Principal Balance of each Group 1 Mortgage Loan with a 40-year
      original term to maturity 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 Fixed Reserve Rate").

(5)   Prior to the 61st Distribution Date, a rate equal to twice the
      Adjustable Rate Loan Group Tax Cap less 11.30% per annum. On and after
      the 61st Distribution Date a rate equal to the Adjustable Rate Loan
      Group Tax Cap. The "Adjustable Rate Loan Group Tax Cap" means the
      weighted average of the Adjusted Net Mortgage Rates of all the Mortgage
      Loans in Loan Group 2 and Loan Group 3. For purposes of this definition,
      beginning on the Distribution Date in August 2016 and ending on the
      Distribution Date in January 2037, the Adjusted Net Mortgage Rate shall
      be determined by first reducing the interest payable on each Group 2 and
      Group 3 Mortgage Loan by the 40-Year Adjustable Reserve Rate (as defined
      below).

(6)   Prior to the 61st Distribution Date, a rate equal to the lesser of (i)
      11.30% per annum and (ii) twice the Adjustable Rate Loan Group Tax Cap.
      On and after the 61st Distribution Date, a rate equal to the Adjustable
      Rate Loan Group Tax Cap.

(7)   On the Closing Date and on each Distribution Date, following the
      allocation of Principal Amounts and Realized Losses in respect of the
      Group 2 and Group 3 Mortgage Loans, the principal balance in respect of
      the SWR-Support Interest will equal the excess of (a) (i) the principal
      balance of the Group 2 and Group 3 Mortgage Loans (as of the end of the
      related Due Period, reduced by principal prepayments received after the
      Due Period that are to be distributed on the Distribution Date related
      to the Due Period) and (ii) the amount, if any, on deposit in the
      Pre-Funding Account in respect of Loan Group 2 and Loan Group 3 over (b)
      the principal balance in respect of the remaining Swap-IO REMIC
      Interests (other than the SWR-1F, SWR-PF, SWR-PV and the SWR-A-R
      Interests).

(8)   A rate equal to the Adjustable Rate Loan Group Tax Cap.

(9)   On each Distribution Date the Class SWR-PV Interest is entitled to all
      Prepayment Charges collected with respect to the Adjustable Rate
      Mortgage Loans. It pays no interest.

(10)  Beginning on the Distribution Date in August 2016 and ending on the
      Distribution Date in January 2037, the SWR-V-40 Year Reserve Interest
      shall be entitled to a specified portion of the interest payable on each
      Group 2 and Group 3 Mortgage Loan. Specifically, the SWR-V-40 Year
      Reserve Interest shall be entitled to a specified portion of the
      interest


                                      5
<PAGE>


      payable on the Stated Principal Balance of each Group 2 and Group 3
      Mortgage Loan with a 40-year original term to maturity 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
      Adjustable Year Reserve Rate").

(11)  The Class 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 Group 1 Mortgage Loans shall
be payable in the following manner:

      (1) Interest. Interest is to be distributed with respect to the SWR-1F
      Interest at the rate described above.

      (2) Principal. Scheduled principal, prepayments and Realized Losses will
      be allocated between the SWR-PF Interest and the SWR-1F in the same way
      that scheduled principal, prepayments and Realized Losses Interest are
      allocated between the Class PF Certificate and all other certificates
      relating to Loan Group 1.

      (3) Prepayment Penalties. All Prepayment Charges related to the Fixed
      Rate Mortgage Loans will be allocated to the SWR-PF Interest.

            On each Distribution Date, the Interest Funds and the Principal
Distribution Amount payable with respect to the Group 2 and Group 3 Mortgage
Loans shall be payable in the following manner:

      (1) Interest. Interest is to be distributed with respect to the Class
      SWR-1A through Class SWR-60B Interests and the Class SWR-Support
      Interests at the rate, or according to the formulas, described above.

      (2) Principal. Scheduled principal, prepayments and Realized Losses will
      be allocated first, to the SWR-Support Interest and second, to the
      numbered classes (Class SWR-1A through Class SWR-60B ) sequentially
      (from lowest to highest). Amounts so allocated to a numbered class
      (Class SWR-1A through Class SWR-60B ) shall be further allocated among
      the "A" and "B" components of such numbered class pro-rata until the
      entire class is reduced to zero.

      (3) Prepayment Penalties. All Prepayment Charges related to the
      Adjustable Rate Mortgage Loans shall be allocated to the SWR-PV
      Interest.

(1)   This Strip REMIC Interest has a principal balance that is initially
      equal to 50% of its Corresponding Certificate Class issued by the Master
      REMIC. Principal payments, both scheduled and prepaid, Realized Losses
      and Subsequent Recoveries with respect to the Class SWR-1F Interest and,
      if necessary, interest accruing on the STR-F-Accrual Interest, will be
      allocated to this class to maintain its size relative to its
      Corresponding Certificate Class (that is, 50%) with any excess payments
      of principal, Realized Losses and Subsequent Recoveries being allocated
      to the STR-F-Accrual Interest in such manner as to cause the principal
      balance of the STR-F-Accrual Interest to have a principal balance equal
      to the sum of (a) 50% of the Loan Group 1 principal balance, (b) 50% of
      the amount, if any, on deposit in the Pre-Funding Account in respect of
      Loan Group 1 and (c) 50% of the Fixed Rate Overcollateralized Amount for
      such Distribution Date.

(2)   The pass-through rate with respect to any Distribution Date (and the
      related Accrual Period) for this Strip REMIC Interest is a per annum
      rate equal to the Loan Group 1 Net Rate Cap.

(3)   The STR-PF Interest is entitled to all amounts collected with respect to
      the SWR-PF Interest. It pays no interest.

      Losses and Subsequent Recoveries attributable to the Swap-IO REMIC
      Interests held by the Strip REMIC (other than the Class SWR-1F, Class
      SWR-PF and SWR-PV Interests) will be allocated to this class to maintain
      its size relative to its Corresponding Certificate Class.

(6)   On each Distribution Date, the pass-through rate will equal the weighted
      average of the pass-through rates of the Swap-IO REMIC Interests (other
      than the Class SWR-1F, Class SWR-PF, Class SWR-PV and Class SWR-A-R
      Interests) treating each "B" Interest the cardinal number of which (for
      example, SWR-1B, SWR-2B, SWR-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 (the "Strip REMIC Cap").

(7)   This Strip REMIC Interest pays no interest.

      by the Strip REMIC (other than the Class SWR-1F, Class SWR-PF, Class
      SWR-PV and Class SWR-A-R Interests) will be allocated to this class to
      maintain its size relative to the Adjustable Rate Overcollateralized
      Amount.

(9)   For each Distribution Date, the STR-CV-Swap-IO Interest is entitled to
      receive from each Swap-IO REMIC "B" Interest the cardinal number of
      which (for example, SWR-1B, SWR-2B, SWR-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.

(10)  The STR-CV-40 Year IO Interest is entitled to all amounts payable with
      respect to the SWR-V-40 Year Reserve Interest.

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
      REMIC Interest at the rate, or according to the formulas, described
      above.

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

      (3) Prepayment Penalties. All Prepayment Charges are allocated as
      described above.

                                      10

      Amount") equal to a specified portion of the interest payable on the
      Strip REMIC Regular Interests having an "F" in their designation (other
      than the STR-F-40 Year IO Interest and the STR-PF Interest) equal to the
      excess of the Loan Group 1 Net Rate Cap over the product of two and the
      weighted average interest rate of the Strip REMIC Regular Interests
      having an "F" in their designation (other than the STR-F-40 Year IO
      Interest and the STR-PF Interest) with each such Class other than the
      STR-F-Accrual Interest, subject to a cap equal to the Pass-Through Rate
      of the Corresponding Master REMIC Class and the STR-F-Accrual Interest
      subject to a cap of 0.00%. The Pass-Through Rate of the Class CF
      Certificates shall be a rate sufficient to entitle it to an amount equal
      to all interest accrued on the Group 1 Mortgage Loans less the interest
      accrued on the other Master REMIC Interests having the letter "F" in
      their designation. The Class CF Distributable Amount for any
      Distribution Date is payable from current interest on the Group 1
      Mortgage Loans and any related Fixed Rate Overcollateralization
      Reduction Amount for that Distribution Date.

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

(6)   For each Interest Accrual Period the Class CV Certificates are entitled
      to an amount (the "Class CV Distributable Amount") equal to the sum of
      (a) the interest payable on the STR-CV-Swap-IO Interest, (b) the
      interest payable on the STR-CV-OC Interest, (c) the interest payable on
      the STR-C-40 Year IO Interest and (d) a specified portion of the
      interest payable on the Strip REMIC Regular Interests having the letter
      "V" in their designation (other than the STR-CV-OC, STR-CV-Swap-IO and
      STR-PV Interests) equal to the excess of the Strip REMIC Cap over the
      weighted average interest rate of the Strip REMIC Regular Interests
      having the letter "V" in their designation (other than the STR-CV-OC,
      STR-CV-Swap-IO and STR-PV 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 CV Certificates shall be a
      rate sufficient to entitle it to an amount equal to all interest accrued
      on the Group 2 and Group 3 Mortgage Loans less the interest accrued on
      the other Master REMIC Interests having the letter "V" in their
      designation. The Class CV Distributable Amount for any Distribution Date
      is payable from current interest on the Group 2 and Group 3 Mortgage
      Loans and any related Adjustable Rate Overcollateralization Reduction
      Amount for that Distribution Date.

(7)   For each Distribution Date the Class PF Certificates are entitled to all
      amounts distributed with respect to the STR-PF Interest.

(8)   For each Distribution Date the Class PV Certificates are entitled to all
      amounts distributed with respect to the STR-PV Interest.

(9)   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


                                      11

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.

            short-term ratings of each such Rating Agency for such securities,
            or such lower ratings as each Rating Agency has confirmed in

            have one of the two highest long term ratings of each Rating
            Agency (except (x) if the Rating Agency is Moody's, such rating
            shall be the highest commercial paper rating of S&P for any such

            Rating Agency or such lower rating as each Rating Agency has
            confirmed in writing is sufficient for the ratings originally

            respective highest applicable rating category or such lower rating
            as each Rating Agency has confirmed in writing is sufficient for
            the ratings originally assigned to the Certificates by such Rating
            Agency (without regard to the Class 1-AF Policy, in the case of
            the Class 1-AF Certificates); and

                  (ix) such other relatively risk free investments having a

            1-AF Policy, in the case of the Class 1-AF Certificates), as

            reasonably acceptable to the NIM Insurer, as evidenced by a signed
            writing delivered by the NIM Insurer;

provided, that no such instrument shall be a Permitted Investment if such
instrument (i) evidences the right to receive interest only payments with
respect to the obligations underlying such instrument, (ii) is purchased at a
premium or (iii) is purchased at a deep discount; provided further that no
such instrument shall be a Permitted Investment (A) if such instrument
evidences principal and interest payments derived from obligations underlying
such instrument and the interest payments with respect to such instrument
provide a yield to maturity of greater than 120% of the yield to maturity at
par of such underlying obligations, or (B) if it may be redeemed at a price
below the purchase price (the foregoing clause (B) not to apply to investments
in units of money market funds pursuant to clause (vii) above); provided
further that no amount beneficially owned by any REMIC (including, without
limitation, any amounts collected by the Master Servicer but not yet deposited
in the Certificate Account) may be invested in investments (other than money
market funds) treated as equity interests for Federal income tax purposes,
unless the Master Servicer shall receive an Opinion of Counsel, at the expense
of Master Servicer, to the effect that such investment will not adversely
affect the status of any such REMIC as a REMIC under the Code or result in
imposition of a tax on any such REMIC. Permitted Investments that are subject
to prepayment or call may not be purchased at a price in excess of par.

            Permitted Transferee: Any Person other than (i) the United States,

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

      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;

      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

      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


                                      71
<PAGE>


"[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 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 120 days of the


                                      72
<PAGE>


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.

            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


                                      73
<PAGE>


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

            Each Seller has entered into this Agreement in consideration for
the purchase of the Mortgage Loans sold by such Seller to the Depositor and
has agreed to take the actions specified herein. The Depositor, concurrently
with the execution and delivery of this Agreement, hereby sells, transfers,
assigns and otherwise conveys to the Trustee for the use and benefit of the
Certificateholders and the Class 1-AF Insurer, without recourse, all right
title and interest in the portion of the Trust Fund not otherwise conveyed to
the Trust Fund pursuant to Sections 2.01(a) or (b).

            Section 2.02 Acceptance by Trustee of the Mortgage Loans.

            (a) The 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, CHL (on behalf of each Seller) and, with
respect to the Group 1 Mortgage Loans only, the Class 1-AF Insurer, an Initial
Certification substantially in the form annexed hereto as Exhibit G-1 to the
effect that, as to each Initial Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Initial Mortgage Loan paid in full or any Initial
Mortgage Loan specifically identified in such certification as not covered by
such certification), the documents described in Section 2.01(g)(i) and, in the
case of each Initial Mortgage Loan that is not a MERS Mortgage Loan, the
documents described in Section 2.01(g)(iii) with respect to such Initial
Mortgage Loans as are in the Co-Trustee's possession and based on its review
and examination and only as to the foregoing documents, such documents appear
regular on their face and relate


                                      74
<PAGE>


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

            Not later than 180 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and CHL (on behalf of each
Seller), the Class 1-AF Insurer and to any Certificateholder that so requests,
a Final Certification with respect to the Initial Mortgage Loans substantially
in the form annexed hereto as Exhibit H, with any applicable exceptions noted
thereon.

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

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

                  (ii) in the case of each Initial Mortgage Loan that is not a
            MERS Mortgage Loan, the original recorded Mortgage or a copy of
            such Mortgage, with


                                      75
<PAGE>


            recording information, and in the case of each Initial Mortgage
            Loan that is a MERS Mortgage Loan, the original Mortgage or a copy
            of such Mortgage, with recording information, noting the presence
            of the MIN of the Initial Mortgage Loan and language indicating
            that the Mortgage Loan is a MOM Loan if the Initial Mortgage Loan
            is a MOM Loan, with evidence of recording indicated thereon, or a
            copy of the Mortgage certified by the public recording office in
            which Mortgage has been recorded;

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

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

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

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

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


                                      76
<PAGE>


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

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

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

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

            (b) The Trustee agrees to execute and deliver on the Subsequent
Transfer Date to the Depositor, the Master Servicer, CHL (on behalf of each
Seller) and, with respect to the Group 1 Mortgage Loans only, an Initial
Certification substantially in the form annexed hereto as Exhibit G-4 to the
effect that, as to each Subsequent Mortgage Loan listed in the Mortgage Loan
Schedule (other than any Subsequent Mortgage Loan paid in full or any
Subsequent Mortgage Loan specifically identified in such certification as not
covered by such certification), the documents described in Section 2.01(g)(i)
and, in the case of each Subsequent Mortgage Loan that is not a MERS Mortgage
Loan, the documents described in Section 2.01(g)(iii), with respect to such
Subsequent Mortgage Loan are in its possession, and based on its review and
examination and only as to the foregoing documents, such documents appear
regular on their face and relate to such Subsequent Mortgage Loan.

            The Trustee agrees to execute and deliver within 30 days after the
Subsequent Transfer Date to the Depositor, the Master Servicer, CHL (on behalf
of each Seller) and, with respect to the Group 1 Mortgage Loans only, an
Interim Certification substantially in the form annexed hereto as Exhibit G-2
to the effect that, as to each Subsequent Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Subsequent Mortgage Loan paid in full or any
Subsequent Mortgage Loan specifically identified in such certification as not
covered by such certification), all documents required to be delivered to it
pursuant to this Agreement with


                                      77
<PAGE>


respect to such Subsequent Mortgage Loan are in its possession (except those
described in Section 2.01(g)(vi)) and based on its review and examination and
only as to the foregoing documents, (i) such documents appear regular on their
face and relate to such Subsequent Mortgage Loan, and (ii) the information set
forth in items (i), (iv), (v), (vi), (viii), (ix) and (xvii) of the definition
of the "Mortgage Loan Schedule" accurately reflects information set forth in
the Mortgage File. On or before the thirtieth (30th) day after the Subsequent
Transfer Date (or if such thirtieth day is not a Business Day, the succeeding
Business Day), the Trustee shall deliver to the Depositor, the Master
Servicer, CHL (on behalf of each Seller) and, with respect to the Group 1
Mortgage Loans only, a Delay Delivery Certification with respect to the
Subsequent Mortgage Loans substantially in the form annexed hereto as Exhibit
G-3, with any applicable exceptions noted thereon, together with a Subsequent
Certification substantially in the form annexed hereto as Exhibit G-4. The
Trustee shall be under no duty or obligation to inspect, review or examine
such documents, instruments, certificates or other papers to determine that
the same are genuine, enforceable or appropriate for the represented purpose
or that they have actually been recorded in the real estate records or that
they are other than what they purport to be on their face.

            Not later than 180 days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, CHL (on behalf of
each Seller), the Class 1-AF Insurer and to any Certificateholder that so
requests a Final Certification with respect to the Subsequent Mortgage Loans
substantially in the form annexed hereto as Exhibit H, with any applicable
exceptions noted thereon.

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

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

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


                                      78
<PAGE>


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

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

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

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

            If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not
meet the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall
include such exceptions in such Final Certification (and the Trustee shall
state in such Final Certification whether any Mortgage File does not then
include the original or duplicate original lender's title policy or a printout
of the electronic equivalent and all riders thereto). If the public recording
office in which a Mortgage or assignment thereof is recorded retains the
original of such Mortgage or assignment, a copy of the original Mortgage or
assignment so retained, with evidence of recording thereon, certified to be
true and complete by such recording office, shall be deemed to satisfy the
requirements of clause (ii), (iii) or (iv) above, as applicable. CHL shall
promptly correct or cure such defect referred to above within 90 days from the
date it was so notified of such defect and, if CHL does not correct or cure
such defect within such period, CHL shall either (A) if the time to cure such
defect expires prior to the end of the second anniversary of the Closing Date,
substitute for the related Subsequent Mortgage Loan a Replacement Mortgage
Loan, which substitution shall be accomplished in the manner and subject to
the conditions set forth in Section 2.03, or (B) purchase such Subsequent
Mortgage Loan from the Trust Fund within 90 days from the date CHL was

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

                  (12) Immediately prior to the assignment of each CHL
      Mortgage Loan to the Depositor, CHL had good title to, and was the sole
      owner of, such CHL Mortgage Loan free and clear of any pledge, lien,

      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;

      cancellation, modification (except as expressly permitted above) or

      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,


                                      84

      such mortgage title insurance policy.

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

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

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

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

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

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

                  (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.

      owner-occupied Mortgaged Properties that are primary residences.

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

                  (38) If the Mortgaged Property is in an area identified in
      the Federal Register by the Federal Emergency Management Agency as
      having special flood hazards, a flood insurance policy in a form meeting
      the requirements of the current guidelines of the Flood Insurance
      Administration is in effect with respect to such Mortgaged Property with
      a generally acceptable carrier in an amount representing coverage not
      less than the


                                      87
<PAGE>


      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 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


                                      88
<PAGE>


      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, Loan Group 2 and Loan Group 3 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, Loan Group 2 and Loan Group 3 range between the approximate
      percentages specified on the Collateral Schedule, and the weighted
      average Gross Margin was approximately the percentage specified in the
      Collateral Schedule.

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

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

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

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

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


                                      89
<PAGE>


      any substantially similar successor provision) and applicable Treasury
      regulations promulgated thereunder.

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

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

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

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

                  (60) If the Mortgage Loan provides that the interest rate on
      the principal balance of the related Mortgage Loan may be adjusted, all
      of the terms of the related 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.


                                      90
<PAGE>


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

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

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

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

                  (65) No Mortgagor has notified CHL or the Master Servicer on
      CHL's behalf, and CHL has no knowledge, of any relief requested or
      allowed to a Mortgagor under the Relief Act or any similar state or
      local law.

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

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

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

                  (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.


                                      91
<PAGE>


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

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

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

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

                  (77) Representations and Warranties relating to the Mortgage

            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


                                      93
<PAGE>


            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 2 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 2 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
            2 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 2 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 2; No proceeds
            from any Mortgage Loan in Loan Group 2 were used to purchase
            single premium credit 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 2 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

<PAGE>


            2 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 2 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, the Master
            Servicer agrees that 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.

            (c) Park Monaco hereby represents and warrants to the Depositor,

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

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

      delivery and performance by Park Monaco of, or compliance by Park Monaco
      with, this Agreement or any Subsequent Transfer Agreement or the
      consummation of the transactions contemplated hereby, or if any such
      consent, approval, authorization or order is required, Park Monaco has
      obtained the same.

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

                  (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 or
the Class 1-AF Insurer in any Mortgage Loan, the party discovering such breach
shall give prompt notice thereof to the other parties, the NIM Insurer, the
Class 1-AF Insurer and the Swap Counterparty. Each of the Master Servicer and
the Sellers (each, a "Representing Party") hereby covenants with respect to
the representations and warranties set forth in Sections 2.03(a) through (d)
that within 90 days of the earlier of the discovery by such Representing Party
or receipt of written notice by such Representing Party from any party of a
breach of any representation or warranty set forth herein made that materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan or the Class 1-AF Insurer, it shall cure such breach in all material
respects and, if such breach is not so cured, shall, (i) if such 90-day period
expires prior to the second anniversary of the Closing Date, remove such
Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and substitute
in its place a Replacement Mortgage Loan, in the manner and subject to the
conditions set forth in this Section; or (ii) repurchase the affected Mortgage
Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner
set forth below; provided that (a) any such substitution pursuant to (i) above
or repurchase pursuant to (ii) above shall not be effected prior to the
delivery to the Trustee, of the Opinion of Counsel required by Section 2.05
hereof, (b) any such substitution pursuant to (i) above shall not be effected
prior to the additional delivery to the Trustee of a Request for File Release
and (c) any such substitution pursuant to (i) above shall


                                      98
<PAGE>


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 Class 1-AF
Insurer, 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 and the Class 1-AF
Insurer the related Mortgage Note, Mortgage and assignment of the Mortgage,
and such other documents and agreements as are required by Section 2.01, with
the Mortgage Note endorsed and the Mortgage assigned as required by Section
2.01. No substitution will be made in any calendar month after the
Determination Date for such month. Scheduled Payments due with respect to
Replacement Mortgage Loans in the Due Period related to the Distribution Date
on which such proceeds are to be distributed shall not be part of the Trust
Fund and will be retained by the applicable Seller delivering such Replacement
Mortgage Loan on such Distribution Date. For the month of substitution,
distributions to Certificateholders will include the Scheduled Payment due on
any Deleted Mortgage Loan for the related Due Period and thereafter the
applicable Seller shall be entitled to retain all amounts received in respect
of such Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage
Loan Schedule for the benefit of the Certificateholders to reflect the removal
of such Deleted Mortgage Loan and the substitution of the Replacement Mortgage
Loan or Loans and the Master Servicer shall deliver the amended Mortgage Loan
Schedule to the Trustee. Upon such substitution, the Replacement Mortgage Loan
or Loans shall be subject to the terms of this Agreement in all respects, and
the applicable Seller delivering such Replacement Mortgage Loan shall be
deemed to have made with respect to such Replacement Mortgage Loan or Loans,
as of the date of substitution, the representations and warranties set forth
in Section 2.03(b), (c) or (d) with respect to such Mortgage Loan. Upon any
such substitution and the deposit to the Certificate Account of the amount
required to be deposited therein in connection with such substitution as
described in the following paragraph, the Co-Trustee shall release to the
Representing Party the Mortgage File relating to such Deleted Mortgage Loan
and held for the benefit of the Certificateholders and shall execute and
deliver at the Master Servicer's direction such instruments of transfer or
assignment as have been prepared by the Master Servicer, in each case without
recourse, as shall be necessary to vest in the applicable Seller, or its
respective designee, title to the Trustee's interest in any Deleted Mortgage
Loan substituted for pursuant to this Section 2.03.


                                      99
<PAGE>


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

            In the event that a Seller shall have repurchased a Mortgage Loan,
the Purchase Price therefor shall be deposited in the Certificate Account
pursuant to Section 3.05 on the Determination Date for the Distribution Date in
the month following the month during which such Seller became obligated to
repurchase or replace such Mortgage Loan and upon such deposit of the Purchase
Price, the delivery of the Opinion of Counsel required by Section 2.05, if any,
and the receipt of a Request for File Release, the 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 and the Class 1-AF Insurer 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:

      its part, the execution, delivery and

                                      100
<PAGE>

      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

                                      101
<PAGE>

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 the any REMIC formed hereunder
to fail to qualify as a REMIC at any time that any Certificates are outstanding.
Any Mortgage Loan as to which repurchase or substitution was delayed pursuant to
this paragraph shall be repurchased or the substitution therefor shall occur
(subject to compliance with Sections 2.02, 2.03 or 2.04) upon the earlier of (a)
the occurrence of a default or imminent default with respect to such loan and
(b) receipt by the Trustee of an Opinion of Counsel to the effect that such
repurchase or substitution, as applicable, will not result in the events
described in clause (i) or clause (ii) of the preceding sentence.

            (b) Upon discovery by the Depositor, any Seller, the Master Servicer
or the Trustee that any Mortgage Loan does not constitute a "qualified mortgage"
within the meaning of section 860G(a)(3) of the Code, the party discovering such
fact shall promptly (and in any event within five Business Days of discovery)
give written notice thereof to the other parties, the Class 1-AF Insurer 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

                                      102
<PAGE>

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 and the Class 1-AF
Insurer, the Master Servicer shall service and administer the Mortgage Loans in
accordance with customary and usual standards of practice of prudent mortgage
loan lenders in the respective states in which the Mortgaged Properties are
located, including taking all required and appropriate actions under each
Required Insurance Policy. In connection with such servicing and administration,
the Master Servicer shall have full power and authority, acting alone and/or
through subservicers as provided in Section 3.02 hereof, subject to the terms
hereof (i) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents, (ii)
to consent to transfers of any Mortgaged Property and assumptions of the
Mortgage Notes and related Mortgages (but only in the manner provided in this
Agreement), (iii) to collect any Insurance Proceeds, other Liquidation Proceeds
and Subsequent Recoveries, and (iv) subject to Section 3.12(b), to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan; provided that the Master Servicer shall take no
action that is inconsistent with or prejudices the interests of the Trustee or
the Certificateholders in any Mortgage Loan or the rights and interests of the
Depositor and the Trustee under this Agreement. The Master Servicer shall
represent and protect the interest of the Trustee in the same manner as it
currently protects its own interest in mortgage loans in its own portfolio in
any claim, proceeding or litigation regarding a Mortgage Loan and shall not make
or permit any modification, waiver or amendment of any term of any Mortgage Loan
which would (i) cause any REMIC formed hereunder to fail to qualify as a REMIC,
(ii) result in the imposition of any tax under section 860(a) or 860(d) of the
Code or (iii) cause any Mortgage Loan in Loan Group 1 to not be covered by the
Pool Insurance Policy, but in any case the Master

                                      103
<PAGE>

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 the Pool Insurance
Policy on behalf of itself, the Sellers, the Depositor, the Class 1-AF Insurer
and the Trustee for the benefit of the Certificateholders and the Class 1-AF
Insurer, when it is necessary to make claims and receive payments under the Pool
Insurance Policy. In connection with its activities as Master Servicer of the
Mortgage Loans, the Master Servicer agrees to present, on behalf of itself, the
Trustee and the Certificateholders, claims to the insurer under any primary
insurance policies and, in this regard, to take any reasonable action necessary
to permit recovery under any primary insurance policies respecting defaulted
Mortgage Loans. Any amounts collected by the Master Servicer under any primary
insurance policies shall be deposited in the Certificate Account.

            The Master Servicer shall take whatever action is appropriate to
maximize the amounts payable under the Pool Insurance Policy and to service the
Mortgage Loans in Loan

                                      104
<PAGE>

Group 1 in the manner required by the Pool Insurance Policy. The Master Servicer
shall prepare and submit all claims eligible for submission under the Pool
Insurance Policy and shall, except as otherwise specified in this Agreement,
perform all of the obligations of the insured under the Pool 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 (without regard
to the Class 1-AF Policy in the case of the Class 1-AF Certificates), as
evidenced by a letter to that effect delivered by each Rating Agency to the
Depositor and the NIM Insurer and (iii) the NIM Insurer shall have consented to
such subservicing agreements (which consent shall not be unreasonably withheld)
with Subservicers, for the servicing and administration of the Mortgage Loans.
The Master Servicer shall deliver to the Trustee copies of all Sub-Servicing
Agreements, and any amendments or modifications thereof, promptly upon the
Master Servicer's execution and delivery of such instruments. The Master
Servicer, with the written consent of the NIM Insurer (which consent shall not
be unreasonably withheld), shall be entitled to terminate any Subservicing
Agreement and the rights and obligations of any Subservicer pursuant to any
Subservicing Agreement in accordance with the terms and conditions of such
Subservicing Agreement. Notwithstanding the provisions of any subservicing
agreement, any of the provisions of this Agreement relating to agreements or
arrangements between the Master Servicer or a subservicer or reference to
actions taken through a Master Servicer or otherwise, the Master Servicer shall
remain obligated and liable to the Depositor, the Trustee and the
Certificateholders for the servicing and administration of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of such subservicing agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Master Servicer
alone were servicing and administering the Mortgage Loans. Every subservicing
agreement entered into by the Master Servicer shall contain a provision giving
the successor

                                      105
<PAGE>

Master Servicer the option to terminate such agreement without cost in the event
a successor Master Servicer is appointed. All actions of each subservicer
performed pursuant to the related subservicing agreement shall be performed as
an agent of the Master Servicer with the same force and effect as if performed
directly by the Master Servicer.

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

            Section 3.03 Rights of the Depositor, the Sellers, the
                         Certificateholders, the NIM Insurer, the Class 1-AF
                         Insurer and the Trustee in Respect of the Master
                         Servicer.

            None of the Trustee, the Sellers, the Certificateholders, the NIM
Insurer, the Class 1-AF 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, the Class 1-AF Insurer and the Trustee, upon reasonable notice,
during normal business hours, access to all records maintained by the Master
Servicer (and any such Subservicer) in respect of the Master Servicer's rights
and obligations hereunder and access to officers of the Master Servicer (and
those of any such Subservicer) responsible for such obligations. Upon request,
the Master Servicer shall furnish to the Depositor, the NIM Insurer, the Class
1-AF Insurer and the Trustee its (and any such Subservicer's) most recent
financial statements and such other information relating to the Master
Servicer's capacity to perform its obligations under this Agreement that it
possesses. To the extent such information is not otherwise available to the
public, the Depositor, the Class 1-AF Insurer, the NIM Insurer and the Trustee
shall not disseminate any information obtained pursuant to the preceding two
sentences without the Masters Servicer's (or any such Subservicer's) written
consent, except as required pursuant to this Agreement or to the extent that it
is necessary to do so (i) in working with legal counsel, auditors, taxing
authorities or other governmental agencies, rating agencies or reinsurers or
(ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or
decree of any court or governmental authority having jurisdiction over the
Depositor, the Trustee, the Class 1-AF Insurer, the NIM Insurer or the Trust
Fund, and in either case, the Depositor, the Class 1-AF Insurer, the NIM Insurer
or the Trustee, as the case may be, shall use its reasonable best efforts to
assure the confidentiality of any such disseminated non-public information. The
Depositor may, but is not obligated to, enforce the obligations of the Master
Servicer under this Agreement and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of the Master Servicer
under this Agreement or exercise the rights of the Master Servicer under this
Agreement; provided by virtue of such performance by the Depositor of its
designee. The Depositor shall not have any responsibility or liability for any
action or failure to act by the Master Servicer and is not obligated to
supervise the performance of the Master Servicer under this Agreement or
otherwise.

            Section 3.04 Trustee to Act as Master Servicer.

            In the event that the Master Servicer shall for any reason no longer
be the Master Servicer hereunder (including by reason of an Event of Default 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 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

                                      107
<PAGE>

Mortgage Loans and Subsequent Mortgage Loans. The Master Servicer shall not be
required to institute or join in litigation with respect to collection of any
payment (whether under a Mortgage, Mortgage Note or otherwise or against any
public or governmental authority with respect to a taking or condemnation) if it
reasonably believes that enforcing the provision of the Mortgage or other
instrument pursuant to which such payment is required is prohibited by
applicable law.

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

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

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

                  (3) all Insurance Proceeds;

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

                  (5) all Compensating Interest;

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

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

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

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

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

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

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

                                      108
<PAGE>

generality of the foregoing, payments in the nature of late payment charges or
assumption fees, if collected, need not be remitted by the Master Servicer. In
the event that the Master Servicer shall remit any amount not required to be
remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time withdraw or direct the institution maintaining the
Certificate Account, to withdraw such amount from the Certificate Account, any
provision herein to the contrary notwithstanding. Such withdrawal or direction
may be accomplished by delivering written notice thereof to the institution
maintaining the Certificate Account, that describes the amounts deposited in
error in the Certificate Account. The Master Servicer shall maintain adequate
records with respect to all withdrawals made pursuant to this Section. All funds
deposited in the Certificate Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08.

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

            (c) The Trustee shall establish and maintain, on behalf of the
Certificateholders and the Class 1-AF Insurer, 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 and the Class 1-AF
Insurer, the Pre-Funding Account, and on the Closing Date, CHL shall remit the
Pre-Funded Amount to the Trustee for deposit in the Pre-Funding Account.

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

                                      109
<PAGE>

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, the Class 1-AF Insurer, 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, the Class 1-AF Insurer, each Rating Agency and
the Depositor of any proposed change of the location of the Distribution
Account, the Pre-Funding Account or the Carryover Reserve Fund prior to any
change thereof.

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

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

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

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

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

            The Master Servicer shall afford the Depositor, the NIM Insurer, the
Trustee and the Class 1-AF Insurer reasonable access to all records and
documentation regarding the Mortgage Loans and all accounts, insurance policies
and other matters relating to this Agreement, such access being afforded without
charge, but only upon reasonable request and during normal business hours at the
offices of the Master Servicer designated by it. Upon request, the Master
Servicer shall furnish to the Trustee and the NIM Insurer its most recent
publicly available financial statements and any other information relating to
its capacity to perform its obligations under this Agreement reasonably
requested by the NIM Insurer.

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

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

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

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

                                      112
<PAGE>

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

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

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

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

            In addition, no later than 1:00 p.m. Pacific time on the
Distribution Account Deposit Date, the Master Servicer shall withdraw from the
Certificate Account and remit to the Trustee the Interest Remittance Amount,
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 $300.00. Funds
on deposit in the Principal Reserve Fund shall not be invested. The Principal
Reserve Fund shall be treated as an "outside reserve fund" under applicable
Treasury regulations and shall not be part of any REMIC created under this
Agreement.

            On the Business Day before the first Distribution Date, the Trustee
shall transfer $100.00 from the Principal Reserve Fund to the Distribution
Account, and on the first Distribution Date, the Trustee shall withdraw $100 and
distribute such amount to the Class A-R Certificates in reduction of the
Certificate Principal Balance thereof.

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

            The Master Servicer shall keep and maintain separate accounting, on
a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to subclauses (i), (ii), (iv),
(v), (vi), (vii), (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.

                                      113
<PAGE>

            (b) The Trustee shall withdraw funds from the Distribution Account
for distribution to the Certificateholders and the Class 1-AF Insurer and
remittance to the Swap Account in the manner specified in this Agreement (and to
withhold from the amounts so withdrawn, the amount of any taxes that it is
authorized to retain pursuant to the third paragraph of Section 8.11). In
addition, the Trustee may from time to time make withdrawals from the
Distribution Account for the following purposes:

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

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

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

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

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

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

            (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
Carryover Reserve Fund for the following purposes:

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

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

            Section 3.09 [Reserved].

            Section 3.10 Maintenance of Hazard Insurance.

            The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the lesser of (i) the

                                      114
<PAGE>

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 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

                                      115
<PAGE>

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

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

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

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

                                      117
<PAGE>

the Master Servicer shall follow such practices and procedures as it shall deem
necessary or advisable and as shall be normal and usual in its general mortgage
servicing activities and the requirements of the insurer under any Required
Insurance Policy; provided that the Master Servicer shall not be required to
expend its own funds in connection with any foreclosure or towards the
restoration of any property unless it shall determine (i) that such restoration
and/or foreclosure will increase the proceeds of liquidation of the Mortgage
Loan after reimbursement to itself of such expenses and (ii) that such expenses
will be recoverable to it through Liquidation Proceeds (respecting which it
shall have priority for purposes of withdrawals from the Certificate Account
pursuant to Section 3.08 hereof). The Master Servicer shall be responsible for
all other costs and expenses incurred by it in any such proceedings; provided
that it shall be entitled to reimbursement thereof from the proceeds of
liquidation of the related Mortgaged Property and any related Subsequent
Recoveries, as contemplated in Section 3.08 hereof. If the Master Servicer has
knowledge that a Mortgaged Property that the Master Servicer is contemplating
acquiring in foreclosure or by deed-in-lieu of foreclosure is located within a
one-mile radius of any site with environmental or hazardous waste risks known to
the Master Servicer, the Master Servicer will, prior to acquiring the Mortgaged
Property, consider such risks and only take action in accordance with its
established environmental review procedures.

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

            In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property as
soon as practicable in a manner that maximizes the Liquidation Proceeds, but in
no event later than three years after its acquisition by the Trust Fund or, at
the expense of the Trust Fund, the Master Servicer shall request, more than 60
days prior to the day on which such three-year period would otherwise expire, an
extension of the three-year grace period. In the event the Trustee shall have
been supplied with an Opinion of

                                      118
<PAGE>

Counsel (such opinion not to be an expense of the Trustee) to the effect that
the holding by the Trust Fund of such Mortgaged Property subsequent to such
three-year period will not result in the imposition of taxes on "prohibited
transactions" of the Trust Fund as defined in section 860F of the Code or cause
any REMIC formed hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding, and the Trust Fund may continue to hold such
Mortgaged Property (subject to any conditions contained in such Opinion of
Counsel) after the expiration of such three-year period. Notwithstanding any
other provision of this Agreement, no Mortgaged Property acquired by the Trust
Fund shall be rented (or allowed to continue to be rented) or otherwise used for
the production of income by or on behalf of the Trust Fund in such a manner or
pursuant to any terms that would (i) cause such Mortgaged Property to fail to
qualify as "foreclosure property" within the meaning of section 860G(a)(8) of
the Code or (ii) subject the Trust Fund to the imposition of any federal, state
or local income taxes on the income earned from such Mortgaged Property under
section 860G(c) of the Code or otherwise, unless the Master Servicer has agreed
to indemnify and hold harmless the Trust Fund with respect to the imposition of
any such taxes. The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding. The income earned from the management of any Mortgaged
Properties acquired through foreclosure or other judicial proceeding, net of
reimbursement to the Master Servicer for expenses incurred (including any
property or other taxes) in connection with such management and net of
unreimbursed Servicing Fees, Advances, Servicing Advances and any management fee
paid or to be paid with respect to the management of such Mortgaged Property,
shall be applied to the payment of principal of, and interest on, the related
defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans
were still current) and all such income shall be deemed, for all purposes in
this Agreement, to be payments on account of principal and interest on the
related Mortgage Notes and shall be deposited into the Certificate Account. To
the extent the income received during a Prepayment Period is in excess of the
amount attributable to amortizing principal and accrued interest at the related
Mortgage Rate on the related Mortgage Loan, such excess shall be considered to
be a partial Principal Prepayment for all purposes hereof.

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

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

            (c) [Reserved].

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

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

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

                                      120
<PAGE>

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 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

                                      121
<PAGE>

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, the Class
1-AF Insurer 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 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

                                      122
<PAGE>

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 The Corridor Contract.

            CHL shall cause The Bank of New York to enter into the Corridor
Contract Administration Agreement and shall assign all of its right, title and
interest in and to the interest rate corridor transaction evidenced by the
Corridor Contract to, and shall cause all of its obligations in respect of such
transaction to be assumed by, the Corridor Contract Administrator, on the terms
and conditions set forth in the Corridor Contract Assignment Agreement. The
Trustee's rights to receive certain proceeds of the Corridor Contract as
provided in the Corridor Contract Administration Agreement will be an asset of
the Trust Fund but will not be an asset of any REMIC. The Trustee shall deposit
any amounts received from time to time with respect to the Corridor Contract
into the Carryover Reserve Fund. The Master Servicer shall deposit any amounts
received on behalf of the Trustee from time to time with respect to the Corridor
Contract into the Carryover Reserve Fund.

            No later than two Business Days following each Distribution Date,
the Trustee shall provide the Corridor Contract Administrator with information
regarding the Certificate Principal Balance of the Class 1-AF-1 Certificates
after all distributions on such Distribution Date.

            The Trustee shall direct the Corridor Contract Administrator to
terminate the Corridor Contract upon the occurrence of certain events of default
or termination events to the extent specified thereunder. Upon any such
termination, the Corridor Contract Counterparty will

                                      123
<PAGE>

be obligated to pay the Corridor Contract Administrator an amount in respect of
such termination, and the portion of such amount that is distributable to the
Trust Fund pursuant to the Corridor Contract Administration Agreement and
received by the Trustee or the Master Servicer for the benefit of the Trust
Fund, as the case may be, in respect of such termination shall be deposited and
held in the Carryover Reserve Fund to pay Net Rate Carryover for the Class
1-AF-1 Certificates as provided in Section 4.04(e) on the Distribution Dates
following such termination to and including the Corridor Contract Termination
Date, but shall not be available for distribution to the Class CF Certificates
pursuant to Section 4.07(c) until such Corridor Contract Termination Date. On
the Corridor Contract Termination Date, after all other distributions on such
date, if any such amount in respect of early termination of the Corridor
Contract remains in the Carryover Reserve Fund, such amounts shall be
distributed by the Trustee to the Class CF Certificates.

            Section 3.20 Prepayment Charges.

            (a) Notwithstanding anything in this Agreement to the contrary, in
the event of a Principal Prepayment in full or in part of a Mortgage Loan, the
Master Servicer may not waive any Prepayment Charge or portion thereof required
by the terms of the related Mortgage Note unless (i) such Mortgage Loan is in
default or the Master Servicer believes that such a default is imminent, and the
Master Servicer determines that such waiver would maximize recovery of
Liquidation Proceeds for such Mortgage Loan, taking into account the value of
such Prepayment Charge, or (ii) (A) the enforceability thereof is limited (1) by
bankruptcy, insolvency, moratorium, receivership, or other similar law relating
to creditors' rights generally or (2) due to acceleration in connection with a
foreclosure or other involuntary payment, or (B) the enforceability is otherwise
limited or prohibited by applicable law. In the event of a Principal Prepayment
in full or in part with respect to any Mortgage Loan, the Master Servicer shall
deliver to the Trustee an Officer's Certificate substantially in the form of
Exhibit T no later than the third Business Day following the immediately
succeeding Determination Date with a copy to the Class P Certificateholders. If
the Master Servicer has waived or does not collect all or a portion of a
Prepayment Charge relating to a Principal Prepayment in full or in part due to
any action or omission of the Master Servicer, other than as provided above, the
Master Servicer shall deliver to the Trustee, together with the Principal
Prepayment in full or in part, the amount of such Prepayment Charge (or such
portion thereof as had been waived) for deposit into the Certificate Account
(not later than 1:00 p.m. Pacific time on the immediately succeeding Master
Servicer Advance Date, in the case of such Prepayment Charge) for distribution
in accordance with the terms of this Agreement.

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

            (c) CHL represents and warrants to the Depositor and the Trustee, as
of the Closing Date and each Subsequent Transfer Date, that the information in
the Prepayment Charge Schedule (including the attached prepayment charge
summary) is complete and accurate in all material respects at the dates as of
which the information is furnished and each Prepayment Charge is permissible and
enforceable in accordance with its terms under applicable state law,

                                      124
<PAGE>

except as the enforceability thereof is limited due to acceleration in
connection with a foreclosure or other involuntary payment.

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

            Section 3.21 Swap Contract.

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

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

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

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

                                      125
<PAGE>

Account unless they are applied in accordance with the ISDA Credit Support Annex
to make a payment due to the Swap Contract Administrator pursuant to the Swap
Contract. If Eligible Credit Support (as defined in the ISDA Credit Support
Annex) with a value equal to the Delivery Amount is not delivered, 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 a Failure to Pay
or Deliver (as defined in the Swap Contract), the Swap Trustee shall direct the
Swap Contract Administrator to demand payment under the Swap Guarantee.

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

            In the event that the swap counterparty in respect of a replacement
swap contract pays any upfront amount to the Swap Contract Administrator in
connection with entering into the replacement swap contract 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 2 and Loan Group 3 pro rata based on their
respective Interest Funds for that Distribution Date and any upfront amount in
excess of the Adjusted 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
shall 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 Swap Certificates
pursuant to Section 4.04(h)(3) through (8) that will remain unpaid following all
distributions to be made on such Distribution Date pursuant to Section 4.04(a)
through (d), (e)(1) through (3) and (f)(1) through (4).

            Any portion of any Net Swap Payment or Swap Termination Payment
payable by the Swap Counterparty and not remitted by the Swap Contract
Administrator to the Swap Trustee

                                      126
<PAGE>

with respect to any Distribution Date will be remitted to CHL and will not be
available to make distributions in respect of any Class of Certificates.

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

                                   ARTICLE IV.
                DISTRIBUTIONS AND ADVANCES BY THE MASTER SERVICER

            Section 4.01 Advances; Remittance Reports.

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

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

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

                                      127
<PAGE>

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

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

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

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

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

Insurer's rights, as applicable, as subrogee for payments distributable pursuant

            (l) For so long as none of the following events shall have occurred
(each such event, a "Class 1-AF Insurer Default"), each Holder of a Class 1-AF
Certificate of that Class agrees that the Class 1-AF Insurer shall be treated by
the Depositor, the Master Servicer and the Trustee as if the Class 1-AF Insurer
were the Holder of all of that Class of Class 1-AF Certificates, for the purpose
(and solely for the purpose) of the giving of any consent, the making of any
direction or the exercise of any voting or other control rights otherwise given

1-AF Insurer fails to make a required payment under the Class 1-AF Policy, (ii)

Receipt on the next succeeding Business Day. If any notice or certificate given
under the Class 1-AF Policy by the Trustee is not in proper form or is not
properly completed, executed or delivered, it shall be deemed not to have been
Received. The Class 1-AF Insurer shall promptly so advise the Trustee and the

required by this Agreement to be sent to the Rating Agencies or the Class 1-AF

            (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

including without limitation, other moneys held by the Trustee pursuant to this
Agreement.

            (b) On each Distribution Date, the Trustee shall deposit all amounts
received in respect of the Corridor Contract in the Carryover Reserve Fund. The

            (d) (1) Funds in the Carryover Reserve Fund in respect of amounts
received under the Corridor Contract may be invested in Permitted Investments at

amounts received under the Corridor Contract shall be invested by the Trustee in
The Bank of New York cash reserves. Any net investment earnings on such amounts
shall be payable pro rata to the Holders of the Class CF Certificates in

of the Majority Holder of the Class CV Certificates (voting as a single Class),
which Permitted Investments shall mature not later than the Business Day

investment (except that if such Permitted Investment is an obligation of the
institution that maintains the Credit Comeback Excess Account, then such
Permitted Investment shall mature not later than such Distribution Date) and
shall not be sold or disposed of prior to maturity. All such Permitted
Investments shall be made in the name of the Trustee, for the benefit of the
Certificateholders. In the absence of such written direction, all funds in the

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.

created hereunder. The Class CF and Class CV

            Section 4.09 Swap Trust and Swap Account.

            On the Closing Date, there is hereby established a separate trust
(the "Swap Trust"), the assets of which shall consist of the Trustee's rights
and obligations under the Swap Contract Administration Agreement. The Swap Trust
shall be maintained by the Swap Trustee, who initially, shall be the Trustee.
The Swap Trustee shall hold the assets of the Swap Trust in trust for the
benefit of the Holders of the Swap Certificates and the Swap Counterparty. No
later than the Closing Date, the Swap Trustee shall establish and maintain a
separate, segregated trust account to be held in the Swap Trust, titled, "Swap
Account, The Bank of New York, as Swap Trustee, in trust for the Swap
Counterparty and the registered holders of CWABS, Inc., Asset-Backed
Certificates, Series 2006-13." Such account shall be an Eligible Account and
funds on deposit therein shall be held separate and apart from, and shall not be
commingled with, any other moneys, including, without limitation, other moneys
of the Trustee held pursuant to this Agreement. Amounts therein shall be held
uninvested. Funds on deposit in the Swap Account shall be distributed in the
amounts and in the order of priority described under Section 4.04(h). For
federal income tax purposes, the Swap Trust, including the Swap Account, shall
be owned by the Class CV Certificates.

            On each Distribution Date, the Trustee shall make a deposit to the
Swap Account pursuant to Section 4.04(b)(i), and to the extent that the amount
of such deposit is insufficient to pay any Net Swap Payment and/or Swap
Termination Payment (other than a Swap Termination Payment due to a Swap
Counterparty Trigger Event) due to the Swap Counterparty with respect to such
Distribution Date, the Trustee shall withdraw, out of amounts on deposit in the
Distribution Account in respect of the Principal Remittance Amount for Loan
Group 2 and Loan Group 3, pro rata on the basis of those respective Principal
Remittance Amounts, such additional amount as is necessary to cover the
remaining portion of any such Net Swap Payment and/or Swap Termination Payment
(other than a Swap Termination Payment due to a Swap Counterparty Trigger Event)
due to the Swap Counterparty with respect to such Distribution Date.

            Section 4.10 Final Maturity Reserve Trust and Final Maturity Reserve
                         Fund.

            (a) On the Closing Date, there is hereby established a separate
trust (the "Final Maturity Reserve Trust"), the assets of which shall consist of
the Final Maturity Reserve Funds.

            (b) On the Closing Date, the Final Maturity Reserve Trustee shall
establish and maintain in its name, in trust for the benefit of the Holders of
the Interest-Bearing Certificates and the Class 1-AF Insurer, the Fixed Rate
Final Maturity Reserve Fund and the Adjustable Rate Final Maturity Reserve Fund
and shall deposit $1,000 into each fund upon receipt from or on behalf of the
Depositor of such amount. Each of Final Maturity Reserve Fund shall be an
Eligible Account, and funds on deposit therein shall be held separate and apart
from, and shall not be commingled with, any other moneys, including without
limitation, other moneys

                                      147
<PAGE>

held by the Trustee pursuant to this Agreement. Neither Final Maturity Reserve
Fund will constitute an asset of the Trust Fund or any REMIC created hereunder.

            The Final Maturity Reserve Trustee shall make deposits to and
withdrawals from the Fixed Rate Final Maturity Reserve Fund and the Adjustable
Rate Final Maturity Reserve Fund as specified in Section 4.04.

            Funds in the Fixed Rate Final Maturity Reserve Fund and the
Adjustable Rate Final Maturity Reserve Fund may be invested in Permitted
Investments at the direction of the Holders of the Class CF and Class CV
Certificates, respectively, 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
Funds, 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 and the
Class 1-AF Insurer. In the absence of such written direction, all funds in the
applicable Final Maturity Reserve Fund shall be invested by the Final Maturity
Reserve Trustee in The Bank of New York cash reserves. Any net investment
earnings on such amounts shall be retained therein until withdrawn as provided
in Section 3.08. Any losses incurred in a Final Maturity Reserve Fund in respect
of any such investments shall be charged against amounts on deposit in that
Final Maturity Reserve Fund (or such investments) immediately as realized. The
Final Maturity Reserve 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
each 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 Funds 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 each Final Maturity Reserve Fund for the
following purposes:

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

            (ii) to clear and terminate such Final Maturity Reserve Fund upon
the termination of this Agreement pursuant to Section 9.01.

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

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

            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 PF, Class PV, Class CF and Class CV Certificates only) (the
"Investment Letter") or Exhibit L (in the case of any Private Certificate) (the
"Rule 144A Letter") or (ii) there shall be delivered to the Trustee at the
expense of the Certificateholder desiring to effect such transfer an Opinion of
Counsel that such Transfer may be made pursuant to an exemption from the
Securities Act; provided, however, that in the case of the delivery of an
Investment Letter in connection with the transfer of any Class C or Class P
Certificate to a transferee that is formed with the purpose of issuing notes
backed by such Class C or Class P Certificate, as the case may

                                      150
<PAGE>

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 Transfer of an ERISA-Restricted Certificate (other than a
transfer of an ERISA-Restricted Certificate to an affiliate of the Depositor
(either directly or through a nominee) in connection with the initial issuance
of the Certificates) shall be made unless the Trustee shall have received either
(i) a representation from the transferee of such Certificate acceptable to and
in form and substance satisfactory to the Trustee (in the event such Certificate
is a Private Certificate, such requirement is satisfied only by the Trustee's
receipt of a representation letter from the transferee substantially in the form
of Exhibit K or Exhibit L, or in the event such Certificate is a Residual
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit
I), to the effect that (x) such transferee is not a Plan, or (y) in the case of
an ERISA-Restricted Certificate that has been the subject of an ERISA-Qualifying
Underwriting, a representation that the transferee is an insurance company which
is purchasing such Certificate with funds contained in an "insurance company
general account" (as such term is defined in section V(e) of Prohibited
Transaction Class Exemption 95-60 ("PTCE 95-60")) and that the purchase and
holding of such Certificate satisfy the requirements for exemptive relief under
Sections I and III of PTCE 95-60 or (ii) in the case of any ERISA-Restricted
Certificate presented for registration in the name of an employee benefit plan
or arrangement subject to ERISA, or a plan or arrangement subject to Section
4975 of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or arrangement or any other person acting on behalf of
any such plan or arrangement, an Opinion of Counsel satisfactory to the Trustee,
addressed to the Trustee and the Master Servicer, to the effect that the
purchase or holding of such ERISA-Restricted Certificate will not result in a
non-exempt prohibited transaction under ERISA or the Code and will not subject
the Trustee or the Master Servicer to any obligation in addition to those
expressly undertaken in this Agreement, which Opinion of Counsel shall not be an
expense of the Trustee, the Master Servicer, or the Trust Fund. For purposes of
the preceding sentence, one of such representations, as appropriate, shall be
deemed to have been made to the Trustee by the transferee's acceptance of an
ERISA-Restricted Certificate (or the acceptance by a Certificate Owner of the
beneficial interest in any such Class of ERISA-Restricted Certificates) unless
the Trustee shall have received from the transferee an Opinion of Counsel as
described in clause (ii) or a representation letter acceptable in form and
substance to the Trustee. Notwithstanding anything else to the contrary herein,
any purported transfer of an ERISA-Restricted Certificate to

                                      151
<PAGE>

or on behalf of an employee benefit plan subject to Section 406 of ERISA or a
plan subject to Section 4975 of the Code without the delivery to the Trustee of
an Opinion of Counsel satisfactory to the Trustee meeting the requirements of
clause (i) of the first sentence of this paragraph as described above shall be
void and of no effect. The Trustee shall be under no liability to any Person for
any registration of transfer of any ERISA-Restricted Certificate that is in fact
not permitted by this Section 5.02(b) or for making any payments due on such
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement so long as the Trustee, with
respect to the transfer of such Classes of Certificates, required delivery of
such certificates and other documentation or evidence as are expressly required
by the terms of this Agreement and examined such certificates and other
documentation or evidence to determine compliance as to form with the express
requirements hereof. The Trustee shall be entitled, but not obligated, to
recover from any Holder of any ERISA-Restricted Certificate that was in fact an
employee benefit plan or arrangement subject to Section 406 of ERISA or a plan
or arrangement subject to Section 4975 of the Code or a Person acting on behalf
of any such plan or arrangement at the time it became a Holder or, at such
subsequent time as it became such a plan or arrangement or Person acting on
behalf of such a plan or arrangement, all payments made on such ERISA-Restricted
Certificate at and after either such time. Any such payments so recovered by the
Trustee shall be paid and delivered by the Trustee to the last preceding Holder
of such Certificate that is not such a plan or arrangement or Person acting on
behalf of a plan or arrangement.

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

            (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

                                      152
<PAGE>

      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 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

                                      153
<PAGE>

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

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

            Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

            If (a) any mutilated Certificate is surrendered to the Trustee, or
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Certificate and of the ownership thereof and (b) there is delivered
to the Master Servicer and the Trustee (and with respect to the Class 1-AF
Certificates, the Class 1-AF Insurer) such security or indemnity as may be
required by them to save each of them harmless, then, in the absence of notice
to the Trustee that such Certificate has been acquired by a bona fide purchaser,
the Trustee shall execute, authenticate and deliver, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate
of like Class, tenor and Percentage Interest. In connection with the issuance of
any new Certificate under this Section 5.03, the Trustee may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time. All
Certificates surrendered to the Trustee under the terms of this Section 5.03
shall be canceled and destroyed by the Trustee in accordance with its standard
procedures without liability on its part.

            Section 5.04 Persons Deemed Owners.

            The Master Servicer, the Trustee, the NIM Insurer, the Class 1-AF
Insurer and any agent of the Master Servicer, the Trustee, the NIM Insurer or
the Class 1-AF Insurer may treat the person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions as provided in this Agreement and for all other purposes
whatsoever, and none of the Master Servicer, the Trustee, the NIM Insurer or the
Class 1-AF Insurer or any agent of the Master Servicer, the Trustee, the NIM
Insurer or the Class 1-AF 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

                                      154
<PAGE>

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

                                      155
<PAGE>

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

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

            Section 5.07 Notices to Depository.

            Whenever any notice or other communication is required to be given
to Certificateholders of 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

                                      156
<PAGE>

Street, New York, New York 10286, Attention: Corporate Trust MBS Administration,
as offices for such purposes. The Trustee will give prompt written notice to the
Certificateholders and the Class 1-AF Insurer of any change in such location of
any such office or agency.

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

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

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

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

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

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

            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
a replacement Master Servicer.

                                      157

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

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

            Section 6.04 Limitation on Resignation of Master Servicer.

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

                                      158
<PAGE>

resignation of the Master Servicer shall be evidenced by an Opinion of Counsel
to such effect delivered to the Trustee. No resignation of the Master Servicer
shall become effective until the Trustee shall have assumed the Master
Servicer's responsibilities, duties, liabilities (other than those liabilities
arising prior to the appointment of such successor) and obligations under this
Agreement 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 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, the Class 1-AF
Insurer and the NIM Insurer (upon such party's reasonable request) with copies
of any such insurance policies and fidelity bond. The Master Servicer shall be
deemed to have complied with this provision if an Affiliate of the Master
Servicer has such errors and omissions and fidelity bond coverage and, by the
terms of such insurance policy or fidelity bond, the coverage afforded
thereunder extends to the Master Servicer.

                                  ARTICLE VII.
                     DEFAULT; TERMINATION OF MASTER SERVICER

            Section 7.01 Events of Default.

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

                  (1) any failure by the Master Servicer to deposit in the
      Certificate Account or the Distribution Account or remit to the Trustee
      any payment (excluding a payment required to be made under Section 4.01
      hereof) required to be made under the terms of this Agreement, which
      failure shall continue unremedied for five calendar days and, with respect
      to a payment required to be made under Section 4.01(b) or (c) hereof, for
      one Business Day, after the date on which written notice of such failure
      shall have been given to the Master Servicer by the Trustee, the NIM
      Insurer, the Class 1-AF Insurer or the Depositor, or to the Trustee, the
      NIM Insurer, the Class 1-AF Insurer and

                                      159
<PAGE>

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

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

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

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

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

            If an Event of Default shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
shall, but only at the direction of either the NIM Insurer or the Holders of
Certificates evidencing not less than 25% of the Voting Rights (subject to the
consent of the Class 1-AF Insurer, which consent shall not be unreasonably
withheld), by notice in writing to the Master Servicer (with a copy to each
Rating Agency and to 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

                                      160
<PAGE>

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 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 pursuant to Section 4.01 hereof or if it
is otherwise unable to so act, (i) appoint any established mortgage loan
servicing institution reasonably acceptable to the NIM Insurer (as evidenced by
the prior written consent of the NIM Insurer), or (ii) if it is unable for 60
days to appoint a successor servicer reasonably acceptable to the NIM Insurer,
petition a court of competent jurisdiction to appoint any established mortgage
loan servicing institution, the appointment of which does not adversely affect
the then-current rating of the Certificates (without regard to the Class 1-AF
Policy, in the case of the Class 1-AF 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 the Pool 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 (without regard to the
Class 1-AF Policy, in the case of the Class 1-AF Certificates). 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 the Class 1-AF Insurer, 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

                                      162
<PAGE>

appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; provided that no such compensation shall be in excess of
that permitted the Master Servicer hereunder. The Trustee and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession. Neither the Trustee nor any other successor
servicer shall be deemed to be in default hereunder by reason of any failure to
make, or any delay in making, any distribution hereunder or any portion thereof
or any failure to perform, or any delay in performing, any duties or
responsibilities hereunder, in either case caused by the failure of the Master
Servicer to deliver or provide, or any delay in delivering or providing, any
cash, information, documents or records to it.

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

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

            Section 7.03 Notification to Certificateholders.

            (a) Upon any termination of or appointment of a successor to the
Master Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, to the Class 1-AF Insurer and to each Rating Agency.

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

                                  ARTICLE VIII.
                    CONCERNING THE TRUSTEE AND THE CO-TRUSTEE

            Section 8.01 Duties of Trustee.

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

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

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

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

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

                  (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

                                      164
<PAGE>

      less than 25% of the Voting Rights of such Class relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Trustee, or exercising any trust or power conferred upon the Trustee
      under this Agreement; and

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

            Section 8.02 Certain Matters Affecting the Trustee.

            (a) Except as otherwise provided in Section 8.01:

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

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

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

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

                                      165
<PAGE>

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

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

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

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

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

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

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

            Section 8.03 Trustee Not Liable for Mortgage Loans.

            The recitals contained herein shall be taken as the statements of
the Depositor or the Master Servicer, as the case may be, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this

                                      166
<PAGE>

Agreement or of any Mortgage Loan or related document or of MERS or the MERS(R)
System other than with respect to the Trustee's execution and authentication of
the Certificates. The Trustee shall not be accountable for the use or
application by the Depositor or the Master Servicer of any funds paid to the
Depositor or the Master Servicer in respect of the Mortgage Loans or deposited
in or withdrawn from the Certificate Account by the Depositor or the Master
Servicer.

            Section 8.04 Trustee May Own Certificates.

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

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

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

            Section 8.06 Eligibility Requirements for Trustee.

            The Trustee hereunder shall, at all times, be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating that would not cause any of the Rating Agencies to reduce their
respective ratings of any Class of Certificates (without regard to the Class
1-AF Policy, in the case of the Class 1-AF 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

                                      167
<PAGE>

this Section 8.06 the combined capital and surplus of such corporation or
association shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 8.06, the Trustee shall resign immediately in the manner and with the
effect specified in Section 8.07 hereof. The corporation or national banking
association serving as Trustee may have normal banking and trust relationships
with the Depositor, the Sellers and the Master Servicer and their respective
affiliates; provided that such corporation cannot be an affiliate of the Master
Servicer other than the Trustee in its role as successor to the Master Servicer.

            Section 8.07 Resignation and Removal of Trustee.

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

            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

                                      168
<PAGE>

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.

            Section 8.08 Successor Trustee.

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

            No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer and its appointment shall not adversely affect the
then-current ratings of the Certificates (without regard to the Class 1-AF
Policy, in the case of the Class 1-AF 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 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

                                      170
<PAGE>

      Trustee hereunder or as successor to the Master Servicer hereunder), the
      Trustee shall be incompetent or unqualified to perform such act or acts,
      in which event such rights, powers, duties and obligations (including the
      holding of title to the Trust Fund or any portion thereof in any such
      jurisdiction) shall be exercised and performed singly by such separate
      trustee or co-trustee, but solely at the direction of the Trustee;

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

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

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

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

            Section 8.11 Tax Matters.

            It is intended that the Trust Fund shall constitute, and that the
affairs of the Trust Fund shall be conducted so that each REMIC created pursuant
to the Preliminary Statement qualifies as, a "real estate mortgage investment
conduit" as defined in and in accordance with the REMIC Provisions. In
furtherance of such intention, the Trustee covenants and agrees that it shall
act as agent (and the Trustee is hereby appointed to act as agent) on behalf of
the Trust 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

                                      171
<PAGE>

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 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

                                      172
<PAGE>

duties as set forth herein. The Depositor hereby indemnifies the Trustee for any
losses, liabilities, damages, claims or expenses of the Trustee arising from any
errors or miscalculations of the Trustee that result from any failure of the
Depositor to provide, or to cause to be provided, accurate information or data
to the Trustee on a timely basis.

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

            The Trustee shall treat the Carryover Reserve Fund and the Swap
Trust, including the Swap Account, as outside reserve funds within the meaning
of Treasury Regulation 1.860G-2(h), neither of which is an asset of any REMIC
created hereunder. The Carryover Reserve Fund shall be treated as owned by the
Class CF and Class CV Certificateholders and the Swap Trust, including the Swap
Account shall be treated as owned by the Class CV 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 (i) the Corridor Contract
Counterparty in respect of any Net Rate Carryover funded by the Corridor
Contract and in respect of any residual payments from such Corridor Contract
received by the Class CF Certificates, (ii) the Holders of the Class CF and
Class CV Certificates in respect of any Net Rate Carryover distributed pursuant
to Sections 4.04(e)(4) and 4.04(f)(4), and (iii) the Swap Counterparty in
respect of any Net Rate Carryover funded by the Swap Contract and in respect of
any residual payments from such Swap Contract received by the Class CV
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, (i) the Trustee shall

                                      173
<PAGE>

assume that the Corridor Contract has a value of $10,000 and (ii) the Trustee
shall treat the $2,225,000 upfront amount received by CHL from the Swap
Counterparty in connection with the execution of the 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 an STR-F-Accrual or STR-CV-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.

            The Trustee shall treat the Fixed Rate 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 CF Certificates and that is not an
asset of any REMIC created hereunder. The Trustee shall treat the rights of the
holders of the Class 1-AF Certificates to receive payments from the Fixed Rate
Final Maturity Reserve Fund as rights in forward purchase contracts entered into
with the Holders of the Class CF Certificates. The Trustee shall treat any
monies set aside in the Fixed Rate Final Maturity Reserve Fund beginning on the
Distribution Date in August 2016 as paid first to the Class CF Certificates,
then deposited in the Fixed Rate Final Maturity Reserve Fund. Any monies
received by the Holders of the Class 1-AF Certificates from the Fixed Rate Final
Maturity Reserve Fund will be treated as monies paid by the Holders of the Class
CF Certificates to acquire the Class 1-AF Certificates receiving such monies.
Thus, the Class 1-AF Certificates and the Class CF 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.

            The Trustee shall treat the Adjustable Rate 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 CV Certificates and that
is not an asset of any REMIC created hereunder. The Trustee shall treat the
rights of the holders of the Class AV and Adjustable Rate Subordinate
Certificates to receive payments from the Adjustable Rate Final Maturity Reserve
Fund as rights in forward purchase contracts entered into with the Holders of
the Class CV Certificates. The Trustee shall treat any monies set aside in the
Adjustable Rate Final Maturity Reserve Fund beginning on the Distribution Date
in August 2016 as paid first to the Class CV Certificates, then deposited in the
Adjustable Rate Final Maturity Reserve Fund. Any monies

                                      174
<PAGE>

received by the Holders of the Class AV and Adjustable Rate Subordinate
Certificates from the Adjustable Rate Final Maturity Reserve Fund will be
treated as monies paid by the Holders of the Class CV Certificates to acquire
the Class AV and Adjustable Rate Subordinate Certificates receiving such monies.
Thus, the Class AV and Adjustable Rate Subordinate Certificates and the Class CV
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.

            Section 8.12 Co-Trustee.

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

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

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

                  (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;

                                      175
<PAGE>

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

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

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

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

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

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

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

            (f) The Master Servicer covenants and agrees (i) to pay to the
Co-Trustee from time to time, and the Co-Trustee shall be entitled to, such
compensation as shall be agreed in writing by the Master Servicer and the
Co-Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) for all services 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

                                      176
<PAGE>

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 (without regard to the Class 1-AF Policy, in the case of the Class
1-AF Certificates) (or having provided such security from time to time as is
sufficient to avoid such reduction). If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.12 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately in
the manner and with the effect specified in paragraph (h) below. The corporation
or national banking association serving as Co-Trustee may have normal banking
and trust relationships with the Depositor, the Sellers and the Master Servicer
and their respective affiliates; provided that such corporation cannot be an
affiliate of the Master Servicer other than the Trustee in its role as successor
to the Master Servicer.

            (h) The Co-Trustee may at any time resign and be discharged from the
trusts hereby created by giving 30 days prior written notice of resignation to
the Trustee, the Depositor and the Master Servicer. Upon such resignation the
Trustee (x) may appoint a successor Co-Trustee meeting the requirements in
paragraph (g) above and acceptable to the Master Servicer and the NIM Insurer
(in their sole discretion), so long as such Co-Trustee executes and delivers to
the other parties hereto an instrument agreeing to be bound by the provisions of
this 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, the Class 1-AF 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 Co-Trustee
shall furnish the Depositor, the Master Servicer, the NIM Insurer, the Class
1-AF 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, the Class 1-AF
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, the Class 1-AF Insurer 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, the Class 1-AF Insurer or the NIM Insurer, the Trustee shall proceed to
protect and enforce its rights and the rights of the Certificateholders, the
Class 1-AF Insurer or the NIM Insurer under this Agreement by a suit, action, or
proceeding in equity or at law or otherwise, whether for the specific
performance of any covenant or agreement contained in this Agreement or in aid
of the execution of any power granted in this Agreement or for the enforcement
of any other legal, equitable, or other remedy, as the Trustee, being advised by
counsel, and subject to the foregoing, shall deem most effectual to protect and
enforce any of the rights of the Trustee, the NIM Insurer, the Class 1-AF
Insurer and the Certificateholders.

                                   ARTICLE IX.
                                   TERMINATION

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

            Subject to Section 9.03, the Trust Fund shall terminate and the
obligations and responsibilities of the Depositor, the Master Servicer, the
Sellers, the Trustee and the Co-Trustee created hereby shall terminate upon the
earlier of (a) the purchase by the Master Servicer or NIM Insurer (the party
exercising such purchase option, the "Terminator") of all of the Mortgage Loans
(and REO Properties) remaining in the Trust Fund at the price equal to the sum
of (i) 100% of the Stated Principal Balance of each Mortgage Loan in the Trust
Fund (other than in respect of an REO Property), (ii) accrued interest thereon
at the applicable Mortgage Rate (or, if such repurchase is effected by the
Master Servicer, at the applicable Net Mortgage Rate), (iii) the appraised value
of any REO Property in the Trust Fund (up to the Stated Principal Balance of the
related Mortgage Loan), such appraisal to be conducted by an appraiser mutually
agreed upon by

                                      178
<PAGE>

the Terminator and the Trustee, (iv) any remaining unpaid costs and damages
incurred by the Trust Fund that arises out of an actual violation of any
predatory or abusive lending law or regulation and (v) if the Terminator is the
NIM Insurer, any unreimbursed Servicing Advances, and the principal portion of
any unreimbursed Advances, made on the Mortgage Loans prior to the exercise of
such repurchase and (b) the later of (i) the maturity or other liquidation (or
any Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and the disposition of all REO Property and (ii) the distribution to
related Certificateholders of all amounts required to be distributed to them

hereby continue beyond the earlier of (i) the expiration of 21 years from the
death of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James's, living on the date
hereof and (ii) the Latest Possible Maturity Date. If any such termination will
result in a Deficiency Amount on the Class 1-AF Policy, the consent of the Class
1-AF Insurer will also be required prior to exercising the option specified in
clause (a) of this paragraph.

            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) unless the Class
1-AF Insurer otherwise consents, the purchase price for such Mortgage Loans and
REO Properties shall result in a final distribution on the Class 1-AF
Certificates and the Class 1-AF Insurer that is sufficient (x) to pay such Class
1-AF Certificates in full (without the need of any Insured Payment) and (y) to
pay any amounts due and payable to the Class 1-AF Insurer pursuant to the terms
hereof and pursuant to the Class 1-AF Insurance and Indemnity Agreement.

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

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

            The Final Maturity Reserve Trust shall terminate on the earlier of

(iii) the termination of this Agreement.

            Section 9.02 Final Distribution on the Certificates.

            If on any Determination Date, (i) the Master Servicer determines
that there are no Outstanding Mortgage Loans and no other funds or assets in the
Trust Fund other than the funds in the Certificate Account, the Master Servicer
shall direct the Trustee to send a final distribution notice promptly to each
related Certificateholder and the Class 1-AF Insurer or (ii) the Trustee

                                      179
<PAGE>

determines that a Class of Certificates shall be retired after a final
distribution on such Class, the Trustee shall notify the related
Certificateholders and the Class 1-AF Insurer within five (5) Business Days
after such Determination Date that the final distribution in retirement of such
Class of Certificates is scheduled to be made on the immediately following
Distribution Date. Any final distribution made pursuant to the immediately
preceding sentence will be made only upon presentation and surrender of the
related Certificates at the Corporate Trust Office of the Trustee. If the
Terminator elects to terminate pursuant to clause (a) of Section 9.01, at least
20 days prior to the date notice is to be mailed to the affected
Certificateholders, such electing party shall notify the Depositor, the Class
1-AF Insurer and the Trustee of the date such electing party intends to
terminate and of the applicable repurchase price of the related Mortgage Loans
and REO Properties.

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

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

            Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to Certificateholders of each affected Class and
the Class 1-AF Insurer the amounts allocable to such Certificates and the Class
1-AF Insurer held in the Distribution Account (and, if applicable, the Carryover
Reserve Fund) in the order and priority set forth in Section 4.04 hereof on the
final Distribution Date and in proportion to their respective Percentage
Interests. Notwithstanding the reduction of the Certificate Principal Balance of
any Class of Certificates to zero, such Class will be outstanding hereunder
(solely for the purpose of receiving distributions (if any) to which it may be
entitled pursuant to the terms of this Agreement and not for any other purpose)
until the termination of the respective obligations and responsibilities of the
Depositor, each Seller, the Master Servicer and the Trustee hereunder in
accordance with Article IX.

            In the event that any affected Certificateholders shall not
surrender related Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Trustee shall give a second
written notice to the remaining Certificateholders to surrender their related
Certificates for cancellation and receive the final distribution with

                                      180
<PAGE>

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

            Section 9.03 Additional Termination Requirements.

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

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

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

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

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

            (c) The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master

                                      181
<PAGE>

Servicer, and the receipt of the Opinion of Counsel referred to in Section
9.03(a)(1), and together with the Holders of the Class A-R Certificates agree to
take such other action in connection therewith as may be reasonably requested by
the Terminator.

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

            Section 10.01 Amendment.

            This Agreement may be amended from time to time by the Depositor,
the Master Servicer, the Sellers, the Trustee and the Co-Trustee with the
consent of the Class 1-AF Insurer (such consent not to be unreasonably withheld)
and the NIM Insurer, without the consent of any of the Certificateholders (i) to
cure any ambiguity, (ii) to correct or supplement any provisions herein, (iii)
to conform this Agreement to the Prospectus Supplement or the Prospectus, (iv)
to modify, alter, amend, add to or rescind any of the terms or provisions
contained in this Agreement to comply with any rules or regulations promulgated
by the Securities and Exchange Commission from time to time, or (v) to make such
other provisions with respect to matters or questions arising under this
Agreement, as shall not be inconsistent with any other provisions herein if such
action shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Certificateholder; provided that any such
amendment shall be deemed not to adversely affect in any material respect the
interests of the Certificateholders and no such Opinion of Counsel shall be
required if the Person requesting such amendment obtains a letter from each
Rating Agency stating that such amendment would not result in the downgrading or
withdrawal of the respective ratings then assigned to the Certificates (without
regard to the Class 1-AF Policy, in the case of the Class 1-AF Certificates), it
being understood and agreed that any such letter in and of itself will not
represent a determination as to the materiality of any such amendment and will
represent a determination only as to the credit issues affecting any such
rating. Any amendment described above made solely to conform this Agreement to
the Prospectus or the Prospectus Supplement shall be deemed not to adversely
affect in any material respect the interests of the Certificateholders.
Notwithstanding the foregoing, no amendment that significantly changes the
permitted activities of the trust created by this Agreement may be made without
the consent of Certificateholders representing not less than 51% of the Voting
Rights of each Class of Certificates affected by such amendment. Each party to
this Agreement hereby agrees that it will cooperate with each other party in
amending this Agreement pursuant to clause (iv) above.

            The Trustee, the Co-Trustee, the Depositor, the Master Servicer and
the Sellers with the consent of the NIM Insurer may also at any time and from
time to time amend this Agreement, without the consent of the
Certificateholders, to modify, eliminate or add to any of its provisions to such
extent as shall be necessary or appropriate to maintain the qualification of the
Trust Fund as a REMIC under the Code or to avoid or minimize the risk of the
imposition of any tax on the Trust Fund pursuant to the Code that would be a
claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee has been provided an Opinion of Counsel,
which opinion shall be an expense of the party requesting such opinion but in
any case shall not be an expense of the Trustee, to the effect that such action
is

                                      182
<PAGE>

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, with the consent of the Class 1-AF Insurer (such consent not to be
unreasonably withheld), 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 Class
1-AF Insurer's consent shall be deemed given to any proposed amendment to this
Agreement if it shall not have objected to such proposed amendment within two
Business Days of receipt of notice of the proposed amendment.

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

            Promptly after the execution of any amendment to this Agreement, the
Trustee shall furnish written notification of the substance of such amendment to
the Class 1-AF Insurer, the Swap Counterparty and, if the amendment required the
consent of Certificateholders, to each Certificateholder and each Rating Agency.

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

                                      183
<PAGE>

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

            Section 10.02 Recordation of Agreement; Counterparts.

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

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

            Section 10.03 Governing Law.

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

            Section 10.04 Intention of Parties.

            (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, the Class 1-AF Insurer and the Swap Counterparty, of a
security interest in all of the assets that constitute the Trust Fund, whether
now owned or hereafter acquired.

                                      184
<PAGE>

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

            (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.

            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 or the Class 1-AF Insurer, the party discovering such breach
shall give prompt written notice to the others, to the Class 1-AF Insurer and to
each Rating Agency.

            If any one or more of the covenants, agreements, provisions or terms
of this Agreement shall be for any reason whatsoever held invalid, then such

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

            Section 10.07 Assignment.

            Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the

            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

                                      187

or winding up of the Trust Fund, or otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

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

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

            Section 10.09 Inspection and Audit Rights.

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

            Section 10.10 Certificates Nonassessable and Fully Paid.

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

            Section 10.11 Rights of NIM Insurer.

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

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

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

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

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

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

            (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.

                                      189
<PAGE>

            (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).

                                   ARTICLE XI.
                             EXCHANGE ACT REPORTING

            Section 11.01 Filing Obligations.

            The Master Servicer, the Trustee and each Seller shall reasonably

Depositor's reporting requirements under the Exchange Act with respect to the
Trust Fund. In addition to the information specified below, if so requested by
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

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

                                      190
<PAGE>

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 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 30 of each year, commencing in 2007 (or such earlier

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

                                      191
<PAGE>

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 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

                                      192
<PAGE>

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, the Class 1-AF Insurer 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, the Class 1-AF Insurer 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

                  (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 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

                                      194
<PAGE>

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 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 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,
the Class 1-AF Insurer 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.

STATE OF      )
              )       ss.:
COUNTY OF     )

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

            1. The undersigned is an officer of _______________, the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, dated as
of July 1, 2006 (the "Agreement"), by and among CWABS, Inc., as 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.)

<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

                        Section 5.02(c) of the Agreement

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

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

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

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

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

<PAGE>

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

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

      will notify each of the parties to which this certification is made of any
      changes in the information and conclusions herein. Until such notice is

      addition, if the Buyer is a bank or savings and loan is provided above,
      the Buyer agrees that it will furnish to such parties updated annual

      account.

      Until the date of purchase of the Certificates, the undersigned will

            3. As to each Mortgage Loan set forth on the attached schedule for
which all or part of the Prepayment Charge required in connection with the
Principal Prepayment was waived by the Master Servicer, such waiver was, as
indicated on the attached schedule, based upon:
