received under the Corridor Contracts) for federal income tax purposes will
consist of four REMICs ("REMIC 1", "REMIC 2", "REMIC 3" and the "Master
REMIC"). Each Certificate, other than the Class A-R Certificate, will
represent ownership of one or more regular interests in the Master REMIC for
purposes of the REMIC Provisions. The Class A-R Certificate represents
ownership of the sole class of residual interest in REMIC 1, REMIC 2, REMIC 3
and the Master REMIC. The Master REMIC will hold as assets the several classes
of uncertificated REMIC 3 Interests. Each REMIC 3 Interest (other than the
R-3-R Interest) is hereby designated as a regular interest in REMIC 3. REMIC 3
will hold as assets the several classes of REMIC 2 Interests (other than the
R-2-R Interest). Each REMIC 2 Interest (other than the R-2-R Interest) is
hereby designated as a regular interest in REMIC 2. REMIC 2 will hold as
assets the several classes of REMIC 1 Interests (other than the R-1-R
Interest). Each REMIC 1 Interest (other than the R-1-R Interest) is hereby
designated as a regular interest in REMIC 1. REMIC 1 will hold as assets all
property of the Trust Fund (excluding the Credit Comeback Excess Account, the
Carryover Reserve Fund, the assets held in the Pre-Funding Account and the

(1)   The Class F Interest will have a principal balance equal to the
      principal balance of the R-1-1-I and R-1-1-S Interests.

(2)   A rate equal to the weighted average of the pass-through rates of the
      R-1-1-I and R-1-1-S Interests (the "Loan Group [1] Net Rate Cap").

(3)   With respect to the Variable Interests, each REMIC 2 Interest having an

      ("SCB") of its Corresponding Loan Group. Each REMIC 2 Interest having an
      "R-2-B-" designation (each, an "R-2-B Interest") will have a principal
      balance initially equal to [0.1]% of the SCB of its Corresponding Loan
      Group. Each REMIC 2 Interest having an "R-2-C-" designation (each, an
      "R-2-C Interest") will have a principal balance initially equal to
      [0.9]% of the Adjusted Subordinated Component Balance ("ASCB") of its
      Corresponding Loan Group. Each REMIC 2 Interest having an "R-2-D-"
      designation (each, an "R-2-D Interest") will have a principal balance
      initially equal to [0.1]% of the ASCB of its Corresponding Loan Group.
      The initial principal balance of each REMIC 2 Interest having an
      "R-2-E-" designation (each, an "R-2-E Interest") will equal the excess
      of its Corresponding Loan Group over the initial aggregate principal
      balances of the R-2-A, R-2-B, R-2-C and R-2-D Interests corresponding to
      such Loan Group.

(4)   A rate equal to the weighted average of the pass-through rates of the

      respect to the Mortgage Loans in Loan Group [2] and Loan Group [3]. It
      pays no interest.

(8)   The R-2-R Interest is the sole class of residual interest in REMIC 2. It
      has no principal balance and pays no principal or interest.

(9)   This REMIC 2 Interest pays no principal.

(10)  This REMIC 2 Interest is entitiled to all amounts payable with respect
      to the R-1-XF Interest.

<PAGE>

(11)  This REMIC 2 Interest is entitiled to all amounts payable with respect
      to the R-1-XV Interest.

           On each Distribution Date, the Interest Funds and the Principal
Distribution Amounts payable with respect to the REMIC 1 Interests shall be
payable with respect to the REMIC 2 Interests in the following manner:

      (1) Interest. Interest is to be distributed with respect to each REMIC 2
Interest at the rate, or according to the formulas, described above.

      (2) Principal. All Principal Distribution Amounts arising with respect
to Loan Group [1] shall be allocated to the Fixed Interests.

      (3) Principal if no Cross-Over Situation Exists. If no Cross-Over
Situation exists with respect to any Variable Interest, then the Principal
Distribution Amounts payable with respect to each Variable Loan Group will be
payable: first to cause the Variable Loan Group's corresponding R-2-A, R-2-B,
R-2-C and R-2-D Interests to equal, respectively, [0.9]% of the SCB, [0.1]% of
the SCB, [0.9]% of the ASCB and [0.1]% of the ASCB, of the Corresponding Loan
Group, and then to the corresponding R-2-E Interest.

      (4) Principal if a Cross-Over Situation Exists. If a Cross-Over
Situation exists with respect to the R-2-A and R-2-B Interests then:

      (a) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is less than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-A Interests prior to any other principal distributions from each such
Variable Loan Group; and

      (b) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is greater than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-B Interests prior to any other principal distributions from each such
Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-A and R-2-B Interests to
equal the Adjustable Rate Subordinate Net Rate Cap. With respect to each
Variable Loan Group, if (and to the extent that) the sum of (a) the principal
payments comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-A and R-2-B Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.

                                      5
<PAGE>

(c) The outstanding aggregate R-2-A and R-2-B Interests for both Variable Loan
Groups will not be reduced below 1 percent of the excess of (i) the aggregate
outstanding Stated Principal Balances of all Variable Loan Groups as of the
end of any Due Period over (ii) the Senior Certificates related to the
Variable Loan Groups as of the related Distribution Date (after taking into
account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (c) prevents the
distribution of principal to the R-2-A and R-2-B Interests of a Variable Loan
Group, and if the Variable Loan Group's corresponding R-2-E Interest has
already been reduced to zero, then the excess principal from that Variable
Loan Group will be paid to the R-2-E Interest of the other Variable Loan
Group, the aggregate R-2-A and R-2-B Interests of which are less than one
percent of the Subordinate Component Balance. If the Variable Loan Group of
the corresponding R-2-E Interest that receives such payment has a Group Net
Rate Cap below the Group Net Rate Cap of the Variable Loan Group making the
payment, then the payment will be treated by REMIC 2 as a Realized Loss.
Conversely, if the Variable Loan Group of the R-2-E Interest that receives
such payment has a Group Net Rate Cap above the Group Net Rate Cap of the
Variable Loan Group making the payment, then the payment will be treated by
REMIC 2 as a reimbursement for prior Realized Losses.

If a Cross-Over Situation exists with respect to the R-2-C and R-2-D Interests
then:

      (d) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is less than the Adjusted Subordinate Net Rate Cap, Principal
Relocation Payments will be made proportionately to the R-2-C Interests prior
to any other principal distributions from each such Variable Loan Group; and

      (e) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is greater than the Adjusted Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-D Interests prior to any other principal distributions from each such
Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-C and R-2-D Interests to
equal the Adjusted Subordinate Net Rate Cap. With respect to each Variable
Loan Group, if (and to the extent that) the sum of (a) the principal payments
comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-C and R-2-D Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.

      (f) The outstanding aggregate R-2-C and R-2-D Interests for all Variable
Loan Groups will not be reduced below 1 percent of the excess of (i) the
aggregate outstanding Stated Principal Balances of all Variable Loan Groups as
of the end of any Due Period over (ii) the Senior Certificates related to the
Variable Loan Groups as of the related Distribution Date (after taking into
account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (f) prevents the
distribution of principal to the R-2-C and R-2-D Interests of a Variable Loan
Group, and if the Variable Loan Group's R-2-

                                      6
<PAGE>

E Interest has already been reduced to zero, then the excess principal from
that Variable Loan Group will be paid to the R-2-E Interests of the other
Variable Loan Group, the aggregate R-2-C and R-2-D Interests of which are less
than one percent of the Adjusted Subordinate Component Balance. If the
Variable Loan Group of the R-2-E Interest that receives such payment has a
Group Net Rate Cap below the Group Net Rate Cap of the Variable Loan Group
making the payment, then the payment will be treated by REMIC 2 as a Realized
Loss. Conversely, if the Variable Loan Group of the R-2- E Interest that
receives such payment has a Group Net Rate Cap above the Group Net Rate Cap of
the Variable Loan Group making the payment, then the payment will be treated
by REMIC 2 as a reimbursement for prior Realized Losses.

      through rate in respect of (i) each of the Class [AF] (other than the
      Class [AF-5B] Certificates), Class MF and Class [BF] Certificates will
      be subject to a cap equal to the Loan Group [1] Net Rate Cap, (ii) the
      Class [AF-5B] Certificates will be subject to a cap equal to the Loan
      Group [1] Net Rate Cap minus the Class [AF-5B] Policy Premium Rate),
      (iii) the Class [2-AV] Certificates will be subject to a cap equal to
      the Loan Group [2] Net Rate Cap, (iv) the Class [3-AV] Certificates will
      be subject to a cap equal to the Loan Group [3] Net Rate Cap, and (v)
      the Class MV Certificates and the Class [BV] Certificates will be
      subject to a cap equal to the Adjusted Subordinate Net Rate Cap. Any
      entitlement of any class of Certificates to Net Rate Carryover will be
      treated as paid by the Master REMIC to the Class [CF] Certificates, in
      the case of the Class [AF] Certificates, the Class MF Certificates and
      the Class [BF] Certificates, and to the Class [CV] Certificates, in the
      case of the Class [AV] Certificates, the Class MV

      Certificates and the Class [BV] Certificates, and then paid to such
      Class of Certificates pursuant to a limited recourse cap contract as
      described in Section 8.11 herein.
(2)   The Class [CF] and Class [CV] Certificates will have Certificate
      Principal Balances equal to the Fixed Rate Overcollateralized Amount and
      Adjustable Rate Overcollateralized Amount, respectively.
(3)   For each Interest Accrual Period the Class [CF] Certificates are
      entitled to an amount (the "Class [CF] Distributable Amount") equal to
      the sum of (a) the interest payable on the R-3-XF Interests and (b) a
      specified portion of the interest on the REMIC 1 Group [1] "I" and "S"
      Interests 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 REMIC 3
      Regular Interests having an "F" designated in the column entitled "REMIC
      3 Interests" (other than the R-3-PF and R-3-XF Interests) with each such
      Class other than the R-3-F-Accrual Interest, subject to a cap equal to
      the Pass-Through Rate of the Corresponding Master REMIC Class and the
      R-3-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 all interest accrued on the REMIC 1 Group [1] "I" and "S"
      Interests less the interest accrued on the other F Class interests
      issued by the Master REMIC. The Class [CF] Distributable Amount for any
      Distribution Date is payable from current interest on the Group [1]
      Mortgage Loans.
(4)   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 R-3-XV Interests and (b) a
      specified portion of the interest on the REMIC 1 Group [2] and Group [3]
      "I" and "S" Interests equal to the excess of the Loan Group [2]/3 Net
      Rate Cap over the product of two and the weighted average interest rate
      of the REMIC 3 Regular Interests having an "V" designated in the column
      entitled "REMIC 3 Interests" (other than the R-3-PV and R-3-XV
      Interests) with each such Class other than the R-3-V-Accrual Interest,
      subject to a cap equal to the Pass-Through Rate of the Corresponding
      Master REMIC Class and the R-3-V-Accrual Interest subject to a cap of
      [0.00]%. The Pass-Through Rate of the Class [CV] Certificates shall be a
      rate sufficient to entitle it to all interest accrued on the REMIC 1
      Group [2] and Group [3] "I" and "S" Interests less the interest accrued
      on the other V Class interests issued by the Master REMIC . The Class
      [CV] Distributable Amount for any Distribution Date is payable from
      current interest on the Group [2] and Group [3] Mortgage Loans.
(5)   For each Distribution Date the Class [PF] and Class [PV] Certificates
      are entitled to all Prepayment Charges distributed with respect to the
      R-3-PF and R-3-PV Interests, respectively.
(6)   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 a
REMIC regular interest, without creating any shortfall--actual or potential
(other than for credit losses) to any REMIC regular interest. It is not
intended that the Class A-R be entitled to any cash flows pursuant to this
agreement except as provided in Sections 4.02(a)(1)(ii) and (iv)(y) hereunder,
(that is, its entitlement to $[100] in the waterfall).

            Whenever used in this Agreement, the following words and phrases,
unless the context otherwise requires, shall have the following meanings:

            Accrual Period: [With respect to any Distribution Date and each
Class of Adjustable Rate Certificates, the period commencing on the
immediately preceding Distribution Date (or, in the case of the first
Distribution Date, the Closing Date) and ending on the day immediately
preceding such Distribution Date. With respect to any Distribution Date and
each Class of Fixed Rate Certificates and the Class [C] Certificates, the
calendar month preceding the month in which such Distribution Date occurs. All
calculations of interest on the Adjustable Rate Certificates will be made on
the basis of the actual number of days elapsed in the related Accrual Period
and on a 360-day year. All calculations of interest on the Fixed Rate
Certificates and Class [C] Certificates will be made on the basis of a 360-day
year consisting of twelve 30-day months].

            Additional Designated Information: As defined in Section 11.02.

            Adjustable Rate Certificates: The Class [AF-1A] Certificates, the
Class [AV] Certificates and the Adjustable Rate Subordinate Certificates.

            Adjustable Rate Cumulative Loss Trigger Event: With respect to a
Distribution Date on or after the Adjustable Rate Stepdown Date, an Adjustable
Rate Cumulative Loss Trigger Event occurs if (x) the aggregate amount of
Realized Losses on the Mortgage Loans in Loan Group [2] and Loan Group [3]
from the Cut-off Date for each such Mortgage Loan to (and including) the last
day of the related Due Period (reduced by the aggregate amount of any
Subsequent Recoveries related to the Mortgage Loans in Loan Group [2] and Loan
Group [3] received through the last day of that Due Period) exceeds (y) the
applicable percentage, for such Distribution Date, of the sum of the aggregate
Cut-off Date Principal Balance of the Initial Mortgage Loans in Loan Group [2]
and Loan Group [3], the Group [2] Pre-Funded Amount and the Group [3]
Pre-Funded Amount, as set forth below:

            Section 2.01 Conveyance of Mortgage Loans.
                         _____________________________

            (a) Each Seller hereby sells, transfers, assigns, sets over and
otherwise conveys to the Depositor, without recourse, all the right, title and
interest of such Seller in and to the applicable Initial Mortgage Loans,
including all interest and principal received and receivable by such Seller on
or with respect to applicable Initial Mortgage Loans after the Initial Cut-off
Date (to the extent not applied in computing the Cut-off Date Principal
Balance thereof) or deposited into the Certificate Account by the Master
Servicer on behalf of such Seller as part of the Initial Certificate Account
Deposit as provided in this Agreement, other than principal due on the
applicable Initial Mortgage Loans on or prior to the Initial Cut-off Date and
interest accruing prior to the Initial Cut-off Date. The Master Servicer
confirms that, on behalf of the Sellers, concurrently with the transfer and
assignment, it or the applicable Seller has deposited into the Certificate
Account the Initial Certificate Account Deposit.

            Immediately upon the conveyance of the Initial Mortgage Loans
referred to in the preceding paragraph, the Depositor (i) sells, transfers,
assigns, sets over and otherwise conveys to the Trustee for benefit of the
Certificateholders and the Class [AF-5B] Insurer, without recourse, all right
title and interest in the Initial Mortgage Loans and (ii) causes the Class
[AF-5B] Insurer to deliver the Class [AF-5B] Policy to the Trustee.

            [CHL] further agrees (x) to cause __________________ to enter into
the Corridor Contract Administration Agreement as Corridor Contract
Administrator and (y) to assign all of its right, title and interest in and to
the interest rate corridor transaction evidenced by each

                                      65
<PAGE>

Confirmation, and to 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.

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

            Immediately upon the conveyance of the Subsequent Mortgage Loans
referred to in the preceding paragraph, the Depositor sells, transfers,
assigns, sets over and otherwise conveys to the Trustee for benefit of the
Certificateholders and the Class [AF-5B] Insurer, without recourse, all right
title and interest in the Subsequent Mortgage Loans.

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

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

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

                (1) the Trustee and the Underwriters will be provided Opinions
      of Counsel addressed to the Rating Agencies as with respect to the sale
      of the Subsequent Mortgage Loans conveyed on such Subsequent Transfer
      Date (such opinions being substantially similar to the opinions
      delivered on the Closing Date to the Rating Agencies with respect to the
      sale of the Initial Mortgage Loans on the Closing Date), to be delivered
      as provided in Section 2.01(f);

                (2) the execution and delivery of such Subsequent Transfer
      Agreement or conveyance of the related Subsequent Mortgage Loans does
      not result in a reduction or

                                      66
<PAGE>

      withdrawal of the any ratings assigned to the Certificates by the
      Ratings Agencies (without regard to the Class [AF-5B] Policy, in the
      case of the Class [AF-5B] Certificates);

                (3) the Depositor shall deliver to the Trustee an Officer's
      Certificate confirming the satisfaction of each of the conditions set
      forth in this Section 2.01(e) required to be satisfied by such
      Subsequent Transfer Date;

                (4) each Subsequent Mortgage Loan conveyed on such Subsequent
      Transfer Date satisfies the representations and warranties applicable to
      it under this Agreement, provided, however, that with respect to a
      breach of a representation and warranty with respect to a Subsequent
      Mortgage Loan set forth in this clause (4), the obligation under Section
      2.03(d) of this Agreement of the applicable Seller, to cure, repurchase
      or replace such Subsequent Mortgage Loan shall constitute the sole
      remedy against such Seller respecting such breach available to
      Certificateholders, the Depositor or the Trustee;

                (5) the Subsequent Mortgage Loans conveyed on such Subsequent
      Transfer Date were selected in a manner reasonably believed not to be
      adverse to the interests of the Certificateholders;

                (6) no Subsequent Mortgage Loan conveyed on such Subsequent
      Transfer Date was [30] or more days delinquent;

                (7) following the conveyance of the Subsequent Mortgage Loans
      on such Subsequent Transfer Date, the characteristics of each Loan Group
      will not vary by more than the amount specified below (other than the
      percentage of Mortgage Loans secured by Mortgaged Properties located in
      the State of California, which will not exceed [50]% of the Mortgage
      Pool and the percentage of mortgage loans in the Credit Grade Categories
      of "C" or below, which will not exceed [10]% of the Mortgage Loans in
      each Loan Group) from the characteristics listed below; provided that
      for the purpose of making such calculations, the characteristics for any
      Initial Mortgage Loan made will be taken as of the Initial Cut-off Date
      and the characteristics for any Subsequent Mortgage Loans will be taken
      as of the Subsequent Cut-off Date;

                (8)none of the Sellers or the Depositor is insolvent and

      the conveyance of Subsequent Mortgage Loans on such Subsequent Transfer
      Date; and

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

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

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

Subsequent Mortgage Loan was conveyed, (3) deposit in the Certificate Account
by the Master Servicer on behalf of the Sellers of the applicable Subsequent
Certificate Account Deposit, and (4) delivery to the Trustee by the Depositor

<PAGE>

shall pay the applicable Seller the Subsequent Transfer Date Transfer Amount
from such funds that were set aside in the Pre-Funding Account pursuant to
Section 2.01(d). The positive difference, if any, between the Subsequent
Transfer Date Transfer Amount and the Subsequent Transfer Date Purchase Amount
shall be re-invested by the Trustee in the Pre-Funding Account.

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

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

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

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

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

                  (iii) in the case of each Mortgage Loan that is not a MERS
            Mortgage Loan, a duly executed assignment of the Mortgage to
            "Asset-Backed Certificates, Series 200_-__, CWHEQ, Inc., by
            __________________, a ___________________, as trustee under the
            Pooling and Servicing Agreement dated as of _________, 200_,
            without recourse" or a copy of such assignment

                                      69
<PAGE>

            with recording information (each such assignment, when duly and
            validly completed, to be in recordable form and sufficient to
            effect the assignment of and transfer to the assignee thereof,
            under the Mortgage to which such assignment relates);

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

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

                  (vi) the original or duplicate original lender's title
            policy or a copy of lender's title policy or a printout of the
            electronic equivalent and all riders thereto or, in the event such
            original title policy has not been received from the insurer, such
            original or duplicate original lender's title policy and all
            riders thereto shall be delivered within one year of the Closing
            Date.

            In addition, in connection with the assignment of any MERS
Mortgage Loan, each Seller agrees that it will cause, at such Seller's own
expense, the MERS(R) System to indicate (and provide evidence to the Trustee
that it has done so) that such Mortgage Loans have been assigned by such
Seller to the Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer
files (a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY
THE FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the 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

                                      70
<PAGE>

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
(a) the State of California or (b) any other 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 and a copy to the Rating Agencies, in lieu of recording
the assignment specified in clause (iii) above, the applicable Seller may
deliver an unrecorded assignment in blank, in form otherwise suitable for
recording to the 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) of the second paragraph of this Section 2.01(g) 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

                                      71
<PAGE>

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) of the second
paragraph of this Section 2.01(g).

            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 above 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

[thirty] days after the Closing Date (in the case of Initial Mortgage Loans)
or within [twenty] days after the related Subsequent Transfer Date (in the
case of Subsequent Mortgage Loans), [CHL] (on behalf of each Seller) shall
either (i) deliver to the Co-Trustee the Mortgage File as required pursuant to
this Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase
the Delay Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage

            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

            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

                                      74

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 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 and [CHL] (on behalf of
each Seller) an Initial Certification substantially in the form annexed hereto
as Exhibit G-4 to the effect that, as to each Subsequent Mortgage Loan listed
in the Mortgage Loan Schedule (other than any Subsequent Mortgage Loan paid in
full or any Subsequent Mortgage Loan specifically identified in such
certification as not covered by such certification), the documents described

the Subsequent Transfer Date to the Depositor, the Master Servicer and [CHL]
(on behalf of each Seller) an Interim Certification substantially in the form

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] day after the Subsequent
Transfer Date (or if such [thirtieth] day is not a Business Day, the
succeeding Business Day), the Trustee shall deliver to the Depositor, the
Master Servicer and [CHL] (on behalf of each Seller) a Delay Delivery
Certification with respect to the Subsequent Mortgage Loans substantially in
the form annexed hereto as Exhibit G-3, with any applicable exceptions noted
thereon, together with a Subsequent Certification substantially in the form

            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) and to any Certificateholder that so requests a Final

      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

      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,

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

Account and, upon receipt of such deposit and Request for File Release with
respect thereto, the Trustee shall release the related Mortgage File to [CHL]
and shall execute and deliver at [CHL]'s request such instruments of transfer
or assignment as [CHL] has prepared, in each case without recourse, as shall
be necessary to vest in [CHL], or a designee, the Trustee's interest in any
Subsequent Mortgage Loan released pursuant hereto. If pursuant to the
foregoing provisions [CHL] repurchases a Subsequent Mortgage Loan that is a

substitute for or to purchase, pursuant to Section 2.02(b), any Subsequent
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect

      of [CHL] or (B) materially conflict with, result in a material breach,
      violation or acceleration of, or result in a material default under, the
      terms of any other material agreement or instrument to which [CHL] is a
      party or by which it may be bound, or (C) constitute a material

      material respects as of the Closing Date.

                  (8) [CHL] will treat the transfer of the [CHL] Mortgage

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

                  (12) Immediately prior to the assignment of each [CHL]
      Mortgage Loan to the Depositor, [CHL] had good title to, and was the
      sole owner of, such [CHL] Mortgage Loan free and clear of any pledge,
      lien, encumbrance or security interest and had full right and authority,

      party, to sell and assign the same pursuant to this Agreement.

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

                  (14) There is no valid offset, claim, defense or

      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

      (18) below.

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

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

                                      82
<PAGE>

      Mortgage; or executed any instrument of release, cancellation,
      modification (except as expressly permitted above) or satisfaction with
      respect thereto.

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

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

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

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

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

                                      83
<PAGE>

      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.

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

                  (32) No less than approximately the percentage specified in
      the Collateral Schedule of the Initial Mortgage Loans in Loan Group [1],
      Loan Group [2] and Loan Group [3] are secured by single family detached
      dwellings. No more than approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group [1],
      Loan Group [2] and Loan Group [3] are secured by two- to

                                      84
<PAGE>

      four-family dwellings. No more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group [1], Loan Group [2] and Loan Group [3] are secured by
      low-rise condominium units. No more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group [1], Loan Group [2] and Loan Group [3] are secured by
      high-rise condominium units. No more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group [1], Loan Group [2] and Loan Group [3] are secured by
      manufactured housing. No more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group [1], Loan Group [2] and Loan Group [3] are secured by PUDs.

                  (33) Each Initial Mortgage Loan in Loan Group [1], Loan
      Group [2] and Loan Group [3] was originated on or after the date
      specified in the Collateral Schedule.

                  (34) Each Initial Mortgage Loan that is an Adjustable Rate
      Mortgage Loan, other than a Two-Year Hybrid Mortgage Loan or a
      Three-Year Hybrid Mortgage Loan, had an initial Adjustment Date no later
      than the applicable date specified on the Collateral Schedule; each
      Initial Mortgage Loan that is a Two-Year Hybrid Mortgage Loan had an
      initial Adjustment Date no later than the applicable date specified on
      the Collateral Schedule; and each Initial Mortgage Loan that is a
      Three-Year Hybrid Mortgage Loan had an initial Adjustment Date no later
      than the applicable date specified on the Collateral Schedule.

                  (35) Approximately the percentage specified in the
      Collateral Schedule of the Initial Mortgage Loans in Loan Group [1],
      Loan Group [2] and Loan Group [3] provide for a prepayment penalty.

                  (36) On the basis of representations made by the Mortgagors
      in their loan applications, no more than approximately the percentage
      specified in the Collateral Schedule of the Initial Mortgage Loans in
      Loan Group [1], Loan Group [2] and Loan Group [3], respectively, are
      secured by investor properties, and no less than approximately the
      percentage specified in the Collateral Schedule of the Initial Mortgage
      Loans in Loan Group [1], Loan Group [2] and Loan Group [3] respectively,
      are secured by owner-occupied Mortgaged Properties that are primary
      residences.

                  (37) At the Cut-off Date, the improvements upon each
      Mortgaged Property are covered by a valid and existing hazard insurance
      policy with a generally acceptable carrier that provides for fire and
      extended coverage and coverage for such other hazards as are customary
      in the area where the Mortgaged Property is located in an amount that is
      at least equal to the lesser of (i) the maximum insurable value of the
      improvements securing such Mortgage Loan or (ii) the greater of (a) the
      outstanding principal balance of the Mortgage Loan and (b) an amount
      such that the proceeds of such policy shall be sufficient to prevent the
      Mortgagor and/or the mortgagee from becoming a co-insurer. If the
      Mortgaged Property is a condominium unit, it is included under the
      coverage afforded by a blanket policy for the condominium unit. All such
      individual insurance policies and all flood policies referred to in item
      (38) below contain a standard

                                      85
<PAGE>

      mortgagee clause naming the applicable Seller or the original mortgagee,
      and its successors in interest, as mortgagee, and the applicable Seller
      has received no notice that any premiums due and payable thereon have
      not been paid; the Mortgage obligates the Mortgagor thereunder to
      maintain all such insurance, including flood insurance, at the
      Mortgagor's cost and expense, and upon the Mortgagor's failure to do so,
      authorizes the holder of the Mortgage to obtain and maintain such
      insurance at the Mortgagor's cost and expense and to seek reimbursement
      therefor from the Mortgagor.

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

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

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

                  (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

                                      86
<PAGE>

      sufficient to pay for every such item that remains unpaid and that has
      been assessed, but is not yet due and payable. Except for (A) payments
      in the nature of escrow payments, and (B) interest accruing from the
      date of the Mortgage Note or date of disbursement of the Mortgage
      proceeds, whichever is later, to the day that precedes by one month the
      Due Date of the first installment of principal and interest, including
      without limitation, taxes and insurance payments, the Master Servicer
      has not advanced funds, or induced, solicited or knowingly received any
      advance of funds by a party other than the Mortgagor, directly or
      indirectly, for the payment of any amount required by the Mortgage.

                  (45) The Mortgage Loans originated by [CHL] were
      underwritten in all material respects in accordance with [CHL]'s
      underwriting guidelines for credit blemished quality mortgage loans or,
      with respect to Mortgage Loans purchased by [CHL] were underwritten in
      all material respects in accordance with customary and prudent
      underwriting guidelines generally used by originators of credit
      blemished quality mortgage loans.

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

                  (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.

                                      87

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

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

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

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

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

                  (57) To the extent required under applicable law, each
      originator and subsequent mortgagee or servicer of the Mortgage Loan
      complied with all licensing requirements and was authorized to transact
      and do business in the jurisdiction in which the related Mortgaged
      Property is located at all times when it held or serviced the 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.

                                      88
<PAGE>

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

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

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

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

                  (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 laws;

                  (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

                                      89
<PAGE>

      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;

      originated in compliance with all applicable federal, state and local

      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
      5.6 Revised, 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;

      the contract was originated (determined pursuant to the REMIC
      Provisions) or (ii) the time the contract is transferred to the
      purchaser. Each Mortgage Loan is a "qualified mortgage" under Section
      860G(a)(3) of the Code;

                  (75) No Mortgage Loan in the Trust Fund is a "high cost

      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

                  (77) Representations and Warranties relating to the Mortgage
      Loans in Loan Group [2]:

                  (i) No Mortgage Loan in Loan Group [2] is covered by the
            Home Ownership and Equity Protection Act of 1994 ("HOEPA");

                  (ii) No borrower was required to purchase any single premium
            credit insurance policy (e.g., life, disability, accident,
            unemployment, or health insurance product) or debt cancellation
            agreement as a condition of obtaining the extension of credit. No
            borrower obtained a prepaid single-premium credit insurance policy
            (e.g., life, disability, accident, unemployment, mortgage, or
            health insurance) in connection with the origination of the
            Mortgage Loan; No proceeds from any Mortgage Loan in Loan Group
            [2] were used to purchase single premium credit insurance policies
            or debt cancellation agreements as part of the origination of, or
            as a condition to closing, such Mortgage Loan;

                  (iii) No Mortgage Loan in Loan Group [2] originated on or
            after October 1, 2002 will impose a prepayment premium for a term
            in excess of three years. Any Mortgage Loan in Loan Group [2]
            originated prior to such date will not impose prepayment penalties
            in excess of five years; and

                  (iv) Each Mortgage Loan in Loan Group [2] had an original
            principal balance that conforms to Freddie Mac guidelines
            concerning original principal balance limits at the time of the
            origination of such mortgage loan.

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

representations and warranties described in this Section that are made to the
best of the Representing Party's knowledge, if it is discovered by any of the
Depositor, the Master Servicer, the Sellers or the Trustee that the substance
of such representation and warranty is inaccurate and such inaccuracy
materially and adversely affects the value of the related Mortgage Loan,
notwithstanding the Representing Party's lack of knowledge with respect to the
substance of such representation or warranty, such inaccuracy shall be deemed
a breach of the applicable representation or warranty.

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

                                      95
<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 with respect to each Mortgage Loan.

            Section 2.04 Representations and Warranties of the Depositor.
                         ________________________________________________

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

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

                  (2) The Depositor has the full corporate power and authority
      to execute, deliver and perform, and to enter into and consummate the
      transactions contemplated by, this Agreement and each Subsequent
      Transfer Agreement and has duly authorized, by all necessary corporate
      action on its part, the execution, delivery and

                                      96
<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

                                      97
<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 and the NIM Insurer. The Depositor hereby covenants with
respect to the representations and warranties made by it in this Section 2.04
that within [90] days of the earlier of the discovery 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
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

                                      98
<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, 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 or (ii) result in the imposition of any tax under section
860(a) or 860(d) of the Code, but in any case the Master Servicer shall not
act in any manner that is a lesser standard than that provided in the first
sentence of this Section

                                      99
<PAGE>

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 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.

            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

                                     100
<PAGE>

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 Fund.

            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 [AF-5B] Policy in the case of the Class [AF-5B]
Certificates), as evidenced by a letter to that effect delivered by each
Rating Agency to the Depositor and the NIM Insurer and (iii) the NIM Insurer
shall have consented to such subservicing agreements (which consent shall not
be unreasonably withheld) with Subservicers, for the servicing and
administration of the Mortgage Loans. The Master Servicer shall deliver to the
Trustee copies of all Sub-Servicing Agreements, and any amendments or
modifications thereof, promptly upon the Master Servicer's execution and
delivery of such instruments. The Master Servicer, with the written consent of
the NIM Insurer (which consent shall not be unreasonably withheld), shall be
entitled to terminate any Subservicing Agreement and the rights and
obligations of any Subservicer pursuant to any Subservicing Agreement in
accordance with the terms and conditions of such Subservicing Agreement.
Notwithstanding the provisions of any subservicing agreement, any of the
provisions of this Agreement relating to agreements or arrangements between
the Master Servicer or a subservicer or reference to actions taken through a
Master Servicer or otherwise, the Master Servicer shall remain obligated and
liable to the Depositor, the Trustee and the Certificateholders for the
servicing and administration of the Mortgage Loans in accordance with the
provisions of this Agreement without diminution of such obligation or
liability by virtue of such subservicing agreements or arrangements or by
virtue of indemnification from the subservicer and to the same extent and
under the same terms and conditions as if the Master Servicer alone were
servicing and administering the Mortgage Loans. Every subservicing agreement
entered into by the Master Servicer shall contain a provision giving the
successor Master Servicer the option to terminate such agreement without cost
in the event a successor Master Servicer is appointed. All actions of each
subservicer performed pursuant to the related 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 [AF-5B]
                         Insurer and the Trustee in Respect of the Master
                         Servicer.
                         _________

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

                                     102
<PAGE>

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.

                         ______________________________________

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

                                     103
<PAGE>

Mortgage Loans on or before the Cut-off Date) and the following amounts
required to be deposited hereunder:

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

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

                  (3) all Insurance Proceeds;

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

                  (5) all Compensating Interest;

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

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

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

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

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

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

            The foregoing requirements for remittance by the Master Servicer
into the Certificate Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of late payment charges or assumption fees, if collected, need not be
remitted by the Master Servicer. In the event that the Master Servicer shall
remit any amount not required to be remitted and not otherwise subject to
withdrawal pursuant to Section 3.08 hereof, it may at any time withdraw or
direct the institution maintaining 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.

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

            (d) If the Pre-Funded Amount is greater than zero, the Trustee
shall establish and maintain, on behalf of the Certificateholders, the
Pre-Funding Account, and on the Closing Date, [CHL] shall remit the Pre-Funded
Amount, to the Trustee for deposit in the Pre-Funding Account.

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

                                     105

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

liable for the amount of any loss incurred in respect of any investment or
lack of investment of funds held in the Certificate Account, the Distribution
Account or the Pre-Funding Account and made in accordance with this Section
3.05.

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

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

                         ________________

            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

                                     106
<PAGE>

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.

            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.

            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;

<PAGE>

            payments of principal and/or interest on such particular Mortgage
            Loan(s) in respect of which any such Advance was made;

                  (iii) [Reserved];

            thereon and not taken into account in determining the related
            Stated Principal Balance of such repurchased Mortgage Loan;

                  (viii) to reimburse the applicable Seller, the Master
            Servicer, the NIM Insurer or the Depositor for expenses incurred

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

            Loan(s) in respect of which any such Advance was made and (y)

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

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

      termination of the Agreement pursuant to Section 9.01 hereof.

                         ----------

            Section 3.10 Maintenance of Hazard Insurance.
                         ________________________________

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

                                     110
<PAGE>

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.

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

            (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of
such conveyance, enforce any due-on-sale clause contained in any Mortgage Note
or Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies
the terms and conditions contained in the Mortgage Note and Mortgage related
thereto and the consent of the mortgagee under such Mortgage Note or Mortgage
is not otherwise so required under such Mortgage Note or Mortgage as a
condition to such transfer. In the event that the Master Servicer is
prohibited by law from enforcing any such due-on-sale clause, or if coverage
under any Required Insurance Policy would be adversely affected, or if
nonenforcement is otherwise permitted hereunder, the Master Servicer is
authorized, subject to Section 3.11(b), to take or enter into an assumption
and modification agreement from or with the person to whom such property has
been or is about to be conveyed, pursuant to which such person becomes liable
under the Mortgage Note and, unless prohibited by applicable state law, the
Mortgagor remains liable thereon, provided that the Mortgage Loan shall
continue to be covered (if so covered before the Master Servicer enters such
agreement) by the applicable Required Insurance Policies. The Master Servicer,
subject to Section 3.11(b), is also authorized 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

                                     111
<PAGE>

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.

                         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

                                     112
<PAGE>

related interest, additions, and penalties imposed on the Trust Fund
established hereunder as a result of any modification of a Mortgage Loan
effected pursuant to this subsection (a), any holding of a Modified Mortgage
Loan by the Trust Fund or any purchase of a Modified Mortgage Loan by [CHL]
(but such obligation shall not prevent [CHL] or any other appropriate Person
from in good faith contesting any such tax in appropriate proceedings and
shall not prevent the [CHL] from withholding payment of such tax, if permitted
by law, pending the outcome of such proceedings). [CHL] shall have no right of
reimbursement for any amount paid pursuant to the foregoing indemnification,
except to the extent that the amount of any tax, interest, and penalties,
together with interest thereon, is refunded to the Trust Fund or the [CHL]. If
the Master Servicer agrees to a modification of any Mortgage Loan pursuant to
this Section 3.12(a), and if such Mortgage Loan carries a Prepayment Charge
provision, [CHL] shall deliver to the Trustee the amount of the Prepayment
Charge, if any, that would have been due had such Mortgage Loan been prepaid
at the time of such modification, for deposit into the Certificate Account
(not later than ____ [Pacific time] on the Master Servicer Advance Date
immediately succeeding the date of such modification) for distribution in
accordance with the terms of this Agreement

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

            With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such
REO Property solely as the Trustee hereunder and not in its individual
capacity. The Master Servicer shall ensure that the title to such REO Property
references this Agreement and the Trustee's capacity thereunder. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall either itself
or through an agent selected by the Master Servicer protect and conserve such
REO Property in the same manner and to such extent as is customary in the
locality where such REO

                                     113
<PAGE>

Property is located and may, incident to its conservation and protection of
the interests of the Certificateholders, rent the same, or any part thereof,
as the Master Servicer deems to be in the best interest of the Master Servicer
and the Certificateholders for the period prior to the sale of such REO
Property. The Master Servicer shall prepare for and deliver to the Trustee a
statement with respect to each REO Property that has been rented showing the
aggregate rental income received and all expenses incurred in connection with
the management and maintenance of such REO Property at such times as is
necessary to enable the Trustee to comply with the reporting requirements of
the REMIC Provisions. The net monthly rental income, if any, from such REO
Property shall be deposited in the Certificate Account no later than the close
of business on each Determination Date. The Master Servicer shall perform the
tax reporting and withholding related to foreclosures, abandonments and
cancellation of indebtedness income as specified by Sections 1445, 6050J and
6050P of the Code by preparing and filing such tax and information returns, as
may be required.

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

                                     114
<PAGE>

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 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

                                     116
<PAGE>

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 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.

                         _______________________

            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.

                         ________________________________

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

            Section 3.17 Annual Statement as to Compliance.
                         __________________________________

            (a) The Master Servicer shall deliver to the Depositor and the

            (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

            Section 3.18 The Corridor Contracts.
                         _______________________

            [CHL] shall cause __________________ 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 transactions evidenced by the
Corridor Contracts to, and shall cause all of its obligations in respect of
such transactions 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
Contracts 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
any 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 any 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 aggregate Certificate Principal Balance of the
Class(es) of Certificates related to each Corridor Contract after all
distributions on such Distribution Date.

            The Trustee shall direct the Corridor Contract Administrator to
terminate a Corridor Contract upon the occurrence of certain events of default
or termination events to the extent specified thereunder. Upon any such
termination, the Corridor Contract Counterparty will be obligated to pay the
Corridor Contract Administrator an amount in respect of such termination, and
the portion of such amount that is distributable to the Trust Fund pursuant to
the Corridor Contract Administration Agreement and received by the Trustee or
the Master Servicer for the benefit of the Trust Fund, as the case may be, in
respect of such termination shall be deposited and held in the Carryover
Reserve Fund to pay Net Rate Carryover for the applicable Classes of
Certificates as provided in Section 4.04(e) on the Distribution Dates
following such termination to and including the applicable Corridor Contract
Termination Date, but shall not be available for distribution to the
applicable Class of Class [C] Certificates pursuant to Section 4.08(c) until
such Corridor Contract Termination Date. On each Corridor Contract Termination
Date, after all other distributions on such date, if any such amounts in
respect of early termination of the related Corridor Contract remain in the
Carryover Reserve Fund, such amounts shall be distributed by the Trustee to
(i) in the case of any such amounts relating to the Class [AF-1A] Corridor
Contract, the Class [CF] Certificates, and (ii) in the case of any such
amounts relating to the Class [2-AV] Corridor Contract, Class [3-AV] Corridor
Contact and Adjustable Rate Subordinate Corridor Contract, the [CV]
Certificates.

            Section 3.19 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

            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

                                     120
<PAGE>

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 _____ [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 the related Mortgaged Property or
related REO Property has been liquidated or until the purchase or repurchase
thereof (or substitution therefor) from the Trustee pursuant to any applicable
provision of this Agreement, except as otherwise provided in this Section
4.01.

            (d) If the Master Servicer determines that it will be unable to
comply with its obligation to make the Advances as and when described in
paragraphs (b) and (c) immediately above, it shall use its best efforts to
give written notice thereof to the Trustee (each such notice a "Trustee
Advance Notice"; and such notice may be given by facsimile), not later than
________, [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 _____, ([New York time]) on a Master Servicer Advance Date, the Trustee
shall, not later than ______, ([New York time]), on the related Distribution
Date, deposit in the Distribution Account an amount equal to the Advance
Deficiency identified in such Trustee Advance Notice unless it is prohibited
from so doing by applicable law. Notwithstanding the foregoing, the Trustee
shall not be required to make such deposit if the Trustee shall have

                                     121
<PAGE>

received written notification from the Master Servicer that the Master
Servicer has deposited or caused to be deposited in the Certificate Account an
amount equal to such Advance Deficiency. All Advances made by the Trustee
pursuant to this Section 4.01(d) shall accrue interest on behalf of the
Trustee at the Trustee Advance Rate from and including the date such Advances
are made to but excluding the date of repayment, with such interest being an
obligation of the Master Servicer and not the Trust Fund. The Master Servicer
shall reimburse the Trustee for the amount of any Advance made by the Trustee
pursuant to this Section 4.01(d) together with accrued interest, not later
than ________ ([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.

                          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.

Policy shall be used solely for payment to the Holders of the Class [AF-5B]
Certificates and may not be applied for any other purpose, including, without
limitation, satisfaction of any costs, expenses or liabilities of the Trustee,
the Master Servicer or the Trust Fund. Any funds remaining in the Class
[AF-5B] Policy Payments Account on the [first] Business Day after each

Certificate by its acceptance of the Class [AF-5B] Certificate agrees, that,
without the need for any further action on the part of the Class [AF-5B]
Insurer or the Trustee, to the extent the Class [AF-5B] Insurer makes
payments, directly or indirectly, on account of principal of or interest on
any Class [AF-5B] Certificates, the Class [AF-5B] Insurer will be fully
subrogated to the rights of the Holders of such Class [AF-5B] Certificates to
receive such principal and interest from the Trust Fund. The Holders of the
Class [AF-5B] Certificates, by acceptance of the Class [AF-5B] Certificates,
assign their rights as Holders of the Class [AF-5B] Certificates to the extent
of the Class [AF-5B] Insurer's interest with respect to amounts paid under the
Class [AF-5B] Policy. Anything herein to the contrary notwithstanding, solely
for purposes of determining the Class [AF-5B] Insurer's rights, as applicable,
as subrogee for payments distributable pursuant to Section 4.04, any payment
with respect to distributions to the Class [AF-5B] Certificates which is made
with funds received pursuant to the terms of the Class [AF-5B] Policy shall
not be considered payment of the Class [AF-5B] Certificates from the Trust
Fund and shall not result in the distribution or the provision for the
distribution in reduction of the Certificate Principal Balance of the Class
[AF-5B] Certificates within the meaning of Article IV.

seeking the avoidance as a preferential transfer (a "Preference Claim") of any
distribution made with respect to the Class [AF-5B] Certificates as to which
it has actual knowledge. Each Holder of a Class [AF-5B] Certificate, by its
purchase of Class [AF-5B] Certificates, and the Trustee hereby agrees that the
Class [AF-5B] Insurer (so long as no Class [AF-5B] Insurer Default exists) may
at any time during the continuation of any proceeding relating to a Preference
Claim direct all matters relating to such Preference Claim, including, without
limitation, (i) the direction of any appeal of any order relating to any
Preference Claim and (ii) the posting of any surety, supersedes or performance
bond pending any such appeal. In addition and without limitation of the
foregoing, the Class [AF-5B] Insurer shall be subrogated to the rights of the
Trustee and each Holder of a Class [AF-5B] Certificate in the conduct of any
Preference Claim, including, without limitation, all rights of any party to an
adversary proceeding action with respect to any court order issued in

of them have ceased to be so authorized prior to the authentication and

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.

Trustee on a continuous basis, an adequate inventory of Certificates to

            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.

                                     147
<PAGE>

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

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

            (b) No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a transfer is to be made in reliance upon an exemption
from the Securities Act and such state securities laws, in order to assure
compliance with the Securities Act and such state securities laws, the
Certificateholder desiring to effect such Transfer and such
Certificateholder's prospective transferee shall (except in connection with
any transfer of a Private Certificate to an affiliate of the Depositor (either
directly or through a nominee) in connection with the initial issuance of the
Certificates) each certify to the Trustee in writing the facts surrounding the
Transfer in substantially the forms set forth in Exhibit J-2 and, in the case
of a Class A-R Certificate, Exhibit J-1 (the "Transferor Certificate") and (i)
deliver a letter in substantially the form of either Exhibit K (in the case of
the Class [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 be, clause (b) and (c) of the form of Investment Letter shall not be
applicable and shall be deleted by such transferee. The Depositor shall
provide to any Holder of a Private Certificate and any prospective transferee
designated by any such Holder, information regarding the related Certificates
and the Mortgage Loans and such other information as shall be necessary to
satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer
of any such Certificate without registration thereof under the Securities Act
pursuant to the registration exemption provided by Rule 144A. The Trustee, the
Co-Trustee and the Master Servicer shall cooperate with the Depositor in
providing the Rule 144A information referenced in the preceding sentence,
including providing to the Depositor such information regarding the
Certificates, the Mortgage Loans and other matters regarding the Trust Fund as
the Depositor shall reasonably request to meet its obligation under the
preceding sentence. Each Holder of a Private Certificate desiring to effect
such Transfer shall, and does hereby agree to, indemnify the Trustee, the
Co-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) on or about the Closing Date) 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

                                     148
<PAGE>

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-1), to the effect that (x) such transferee is not 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 or using the assets of any such plan or arrangement, 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 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

406 of ERISA or a plan or arrangement subject to Section 4975 of the Code or a

or Person acting on behalf of such a plan or arrangement, all payments made on

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.

            (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) on
      or about the Closing Date, 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 an affidavit (a "Transfer Affidavit") of
      the initial owner or the proposed transferee in the form attached hereto
      as Exhibit I-1.

                  (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

                                     150
<PAGE>

      Certificate at and after either such time. Any such payments so
      recovered by the Trustee shall be paid and delivered by the Trustee to
      the last preceding Permitted Transferee of such Certificate.

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

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

            (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 [AF-5B] Certificates, the Class [AF-5B] 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.

Certificateholders or Certificate Owners desire to communicate with other
Certificateholders or Certificate Owners with respect to their rights under
this Agreement or under the Certificates and (c) provide a copy of the

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

<PAGE>

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

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

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

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

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

                         ________________________

            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

                                     153

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.

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 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

order to comply with its reporting obligation under Item 6.02 of Form 8-K with

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

            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 [AF-5B] Policy). Any such determination
pursuant to clause (i) of the preceding sentence permitting the resignation of
the Master Servicer shall be evidenced by an Opinion of Counsel to such effect
delivered to the Trustee. No resignation of the Master Servicer shall become
effective until the Trustee shall have assumed the Master Servicer's
responsibilities, duties, liabilities (other than those liabilities arising
prior to the appointment of such successor) and obligations under this
Agreement 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.

                         _______________________________________________

            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 [AF-5B]
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.

      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,

                  (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

<PAGE>

                  (6) the Master Servicer shall fail to reimburse in full the
      Trustee not later than ______ ([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 (a) 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 [AF-5B] Insurer, which consent shall not
be unreasonably withheld), by notice in writing to the Master Servicer (with a
copy to each Rating Agency), terminate all of the rights and obligations of
the Master Servicer under this Agreement and in and to the Mortgage Loans and
the proceeds thereof, other than its rights as a Certificateholder hereunder.
In addition, if during the period that the Depositor is required to file
Exchange Act Reports with respect to the Trust Fund, the Master Servicer shall
fail to observe or perform any of the obligations that constitute a Limited
Exchange Act Reporting Obligation or the obligations set forth in Section
3.17(a) or Section 11.01(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 termintate
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 the 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

                                     158
<PAGE>

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 [AF-5B] Policy, in the case of the Class [AF-5B]
Certificates) and the NIM Insurer guaranteed notes (without giving any effect
to any policy or guaranty provided by the NIM Insurer) by each Rating Agency
as the successor to the Master Servicer hereunder in the assumption of all or
any part of the responsibilities, duties or liabilities of the Master Servicer
hereunder. Any successor Master Servicer shall be an institution that is a
Fannie Mae and Freddie Mac approved seller/servicer in good standing, that has
a net worth of at least $[15,000,000] and that is willing to service the
Mortgage Loans and executes and delivers to the Depositor and the Trustee an
agreement accepting such delegation and assignment, that contains an
assumption by such Person of the rights, powers, duties, responsibilities,
obligations and liabilities of the Master Servicer (other than liabilities and
indemnities of the Master Servicer under Section 6.03 hereof incurred prior to
termination of the Master Servicer under Section 7.01), with like effect as if
originally named as a party to this Agreement; and provided further that each
Rating Agency acknowledges that its rating of the Certificates in effect
immediately prior to such assignment and delegation will not be qualified or
reduced as a result of such assignment and delegation (without regard to the
Class [AF-5B] Policy, in the case of the Class [AF-5B] 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

                                     159
<PAGE>

appointment shall have been provided by the Trustee to each Certificateholder
and the Class [AF-5B] 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 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
Co-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.

Master Servicer, the Trustee shall give prompt written notice thereof to
Certificateholders, to the Class [AF-5B] 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.

                   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;

                                     161
<PAGE>

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

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

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

            Section 8.02 Certain Matters Affecting the Trustee.
                         ______________________________________

            (a) Except as otherwise provided in Section 8.01:

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

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

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

                  (4) prior to the occurrence of an Event of Default hereunder
      and after the curing of all Events of Default that may have occurred,
      the Trustee shall not be bound to make any investigation into the facts
      or matters stated in any resolution, certificate, statement, instrument,
      opinion, report, notice, request, consent, order, approval, bond or
      other paper or document, unless requested in writing so to do by the NIM
      Insurer or the Holders of each Class of Certificates evidencing not less
      than [25]% of the Voting Rights of such Class; provided, however, that
      if the payment within a reasonable time to the

                                     162
<PAGE>

      Trustee of the costs, expenses or liabilities likely to be incurred by
      it in the making of such investigation is, in the opinion of the Trustee
      not reasonably assured to the Trustee by the NIM Insurer or such
      Certificateholders, the Trustee may require reasonable indemnity against
      such expense, or liability from the NIM Insurer or such
      Certificateholders as a condition to taking any such action;

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

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

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

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

                  (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 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

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
[AF-5B] Policy, in the case of the Class [AF-5B] Certificates) below the
ratings issued on the Closing Date (or having provided such security from time
to time as is sufficient to avoid such reduction). If such corporation or
association publishes reports of condition at least annually, pursuant to law
or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section 8.06 the combined capital and surplus of
such corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the

                                     164

effect specified in Section 8.07 hereof. The corporation or national banking
association serving as Trustee may have normal banking and trust relationships
with the Depositor, the Sellers and the Master Servicer and their respective
affiliates; provided that such corporation cannot be an affiliate of the
Master Servicer other than the Trustee in its role as successor to the Master
Servicer.

            Section 8.07 Resignation and Removal of Trustee.
                         ___________________________________

            The Trustee may at any time resign and be discharged from the
trusts hereby created by (1) giving written notice of resignation to the
Depositor and the Master Servicer and by mailing notice of resignation by
first class mail, postage prepaid, to the Certificateholders at their
addresses appearing on the Certificate Register and each Rating Agency, not
less than [60] days before the date specified in such notice when, subject to
Section 8.08, such resignation is to take effect, and (2) acceptance of
appointment by a successor trustee in accordance with Section 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, in 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, and in the case of clause (iv), the Depositor, may remove the
Trustee and appoint a successor trustee, reasonably acceptable to the NIM
Insurer, by written instrument, in triplicate, one copy of which instrument
shall be delivered to the Trustee, one copy of which shall be delivered to the
Master Servicer and one copy of which shall be delivered to the successor
trustee.

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

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

            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 any 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.

            No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee
shall be eligible under the provisions of Section 8.06 hereof, is reasonably
acceptable to the NIM Insurer, its appointment shall not adversely affect the
then-current ratings of the Certificates (without regard to the Class [AF-5B]
Policy, in the case of the Class [AF-5B] 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

                                     166
<PAGE>

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 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;

                                     167
<PAGE>

                  (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 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)

                                     168
<PAGE>

prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary,
state tax authorities, all information returns and reports as and when
required to be provided to them in accordance with the REMIC Provisions,
including without limitation, the calculation of any original issue discount
using the Prepayment Assumption; (e) provide information necessary for the
computation of tax imposed on the transfer of a Class A-R Certificate to a
Person that is not a Permitted Transferee, or an agent (including a broker,
nominee or other middleman) of a Non-Permitted Transferee, or a pass-through
entity in which a Non-Permitted Transferee is the record holder of an interest
(the reasonable cost of computing and furnishing such information may be
charged to the Person liable for such tax); (f) to the extent that they are
under its control conduct the affairs of the Trust Fund at all times that any
Certificates are outstanding so as to maintain the status of each REMIC
created hereunder as a REMIC under the REMIC Provisions; (g) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any REMIC created hereunder; (h) pay, from
the sources specified in the penultimate paragraph of this Section 8.11, the
amount of any federal, state and local taxes, including prohibited transaction
taxes as described below, imposed on any REMIC created hereunder prior to the
termination of the Trust Fund when and as the same shall be due and payable
(but such obligation shall not prevent the Trustee or any other appropriate
Person from contesting any such tax in appropriate proceedings and shall not
prevent the Trustee from withholding payment of such tax, if permitted by law,
pending the outcome of such proceedings); (i) sign or cause to be signed
federal, state or local income tax or information returns; (j) maintain
records relating to each REMIC created hereunder, including but not limited to
the income, expenses, assets and liabilities of each such REMIC, and the fair
market value and adjusted basis of the Trust Fund property determined at such
intervals as may be required by the Code, as may be necessary to prepare the
foregoing returns, schedules, statements or information; and (k) as and when
necessary and appropriate, represent the Trust Fund in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year
of any REMIC created hereunder, enter into settlement agreements with any
governmental taxing agency, extend any statute of limitations relating to any
tax item of the Trust Fund, and otherwise act on behalf of any REMIC created
hereunder in relation to any tax matter involving any such REMIC.

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

                                     169
<PAGE>

            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 the 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 as an outside
reserve fund within the meaning of Treasury Regulation 1.860G-2(h) that is
owned by the Holders of the Class [C] Certificates, and that is not an asset
of any REMIC created hereunder. The Trustee shall treat the rights of the
Holders of each Class of Certificates (other than the Class [P] and Class A-R
Certificates) to receive payments from the Carryover Reserve Fund as rights in
an interest rate corridor contract written by: (i) the Corridor Contract
Counterparty in respect of any Net Rate Carryover funded by any Corridor
Contract and in respect of any residual payments from such Corridor Contract
received by the Classs [CF] or Classs [CV] Certificates, as the case may be,
and (ii) the Holders of the Classs [CF] and Classs [CV] Certificates in
respect of (a) any monies distributed pursuant to Sections 4.04(e)(20) and
4.04(f)(21) herein, in favor of the other Certificateholders. Thus, the Class
[AF-1A], Class [2-AV] and Class [3-AV] Certificates and the Adjustable Rate
Subordinate Certificates, shall be treated as representing ownership of not
only an Master REMIC regular interest, but also ownership of an interest in an
interest rate corridor contract. For purposes of determining the issue price
of the Master REMIC regular interests, the Trustee shall assume that the Class
[AF-1A] Corridor Contract, the Class [2-AV] Corridor Contract, the Class
[3-AV] Corridor Contract and the Adjustable Rate Subordinate Corridor Contract
have values of $________, $________, $________ and $_______, respectively. The
Trustee shall treat the entitlement to Credit Comeback Excess Amounts as owned
by the Holders of the Classs [CF] 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 Classs [CF] Certificates as payments made by the Holders of the Classs
[CF] Certificates pursuant to a credit enhancement contract under Treasury
Regulation 1.860G-2(c). The Trustee shall also treat any amount payable to a
Classs [CF] Certificate with respect to an R-3-X Interest as deposited into
the Carryover Reserve Fund.

                         -----------

            (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 Trustee, unless the Co-Trustee
      was grossly negligent or acted in bad faith or with willful misfeasance.

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

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

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

                  (3) the Co-Trustee shall not be liable, individually or as
      Co-Trustee, for any action taken, suffered or omitted by it in good
      faith and believed by it to be

                                     171
<PAGE>

      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 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

                                     172
<PAGE>

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 (without regard to the Class
[AF-5B] Policy, in the case of the Class [AF-5B] Certificates) below the
ratings issued on the Closing Date (or having provided such security from time
to time as is sufficient to avoid such reduction). If such corporation or
association publishes reports of condition at least annually, pursuant to law
or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section 8.12 the combined capital and surplus of
such corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Co-Trustee shall cease to be eligible in accordance with
the provisions of this Section 8.12, the Co-Trustee shall resign immediately
in the manner and with the effect specified in paragraph (h) below. The
corporation or national banking association serving as Co-Trustee may have
normal banking and trust relationships with the Depositor, the Sellers and the
Master Servicer and their respective affiliates; provided that such
corporation 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. 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 Co-Trustee. If at any time the Co-Trustee
fails to comply with its obligations under this Section 8.13(h) and 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 the Depositor may remove
the Co-Trustee. Upon such resignation or removal, 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. Prior to
any merger or consolidation of the Co-Trustee, at least 15 calendar days prior
to the effective date of any merger or consolidation of

                                     173

                         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

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

            The right to purchase all Mortgage Loans and REO Properties by the
Terminator pursuant to clause (a) of the immediately preceding paragraph shall

[AF-5B] Certificates and the Class [AF-5B] Insurer that is sufficient (x) to
pay such Class [AF-5B] Certificates in full and (y) to pay any amounts due and
payable to the Class [AF-5B] Insurer pursuant to the terms hereof.

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

            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 related to such
Loan Group, the Master Servicer shall direct the Trustee to send a final
distribution notice promptly to each related Certificateholder and the Class
[AF-5B] Insurer or (ii) the Trustee determines that a Class of Certificates
shall be retired after a final distribution on such Class, the Trustee shall
notify the related Certificateholders and the Class [AF-5B] Insurer within
[five] 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

                                     175
<PAGE>

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 [AF-5B] 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 [AF-5B] Insurer the amounts allocable to such Certificates and the
Class [AF-5B] Insurer held in the Distribution Account (and, if applicable,
the Carryover Reserve Fund) in the order and priority set forth in Section
4.04 hereof on the final Distribution Date and in proportion to their
respective Percentage Interests. Notwithstanding the reduction of the
Certificate Principal Balance of any Class of Certificates to zero, such Class
will be outstanding hereunder (solely for the purpose of receiving
distributions (if any) to which it may be entitled pursuant to the terms of
this Agreement and not for any other purpose) until the termination of the
respective obligations and responsibilities of the Depositor, each Seller, the
Master Servicer and the Trustee hereunder in accordance with Article IX.

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

                                     176
<PAGE>

Certificates shall not have been surrendered for cancellation, the Class
[AF-5B] Insurer, with respect to any unpaid Class [AF-5B] Reimbursement
Amounts (only to the extent of amounts received in respect of the Group [1]
Mortgage Loans), and then the Class A-R Certificates shall be entitled to all
unclaimed funds and other assets that remain subject hereto.

            Section 9.03 Additional Termination Requirements.
                         ____________________________________

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

                  (1) The Master Servicer shall establish a __-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 __-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 __-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 __-day
liquidation period for each the REMIC was the date on which the Trustee sold
the assets of the Trust Fund to the Terminator.

            (c) The Trustee as agent for each REMIC created hereunder hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Master Servicer, and the receipt of the Opinion of Counsel
referred to in Section 9.03(a)(1), and together with the Holders of the Class
A-R Certificates agree to take such other action in connection therewith as
may be reasonably requested by the Terminator.

                           MISCELLANEOUS PROVISIONS

            Section 10.01 Amendment.
                          __________

            This Agreement may be amended from time to time by the Depositor,
the Master Servicer, the Sellers, the Co-Trustee and the Trustee with the
consent of the NIM Insurer, without the consent of any of the
Certificateholders (i) to cure any ambiguity, (ii) to correct or supplement
any provisions herein, (iii) to conform this Agreement to the Prospectus
Supplement or the Prospectus, (iv) to modify, alter, amend, add to or rescind
any of the terms or provisions contained in this Agreement to comply with any
rules or regulations promulgated by the Securities and Exchange Commission
from time to time, or (v) to make such other provisions with respect to
matters or questions arising under this Agreement, as shall not be
inconsistent with any other provisions herein if such action shall not, as
evidenced by an Opinion of Counsel, adversely affect in any material respect
the interests of any Certificateholder; provided that any such amendment shall
be deemed not to adversely affect in any material respect the interests of the
Certificateholders and no such Opinion of Counsel shall be required if the
Person requesting 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 [AF-5B] Policy, in the case of the Class [AF-5B] 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 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 Co-Trustee and the Trustee
with the consent of the NIM Insurer and the Holders of each Class of
Certificates affected thereby evidencing not less than [51]% of

                                     178
<PAGE>

the Voting Rights of such Class for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement
or of modifying in any manner the rights of the Holders of Certificates;
provided that no such amendment shall (i) reduce in any manner the amount of,
or delay the timing of, payments required to be distributed on any Certificate
without the consent of the Holder of such Certificate, (ii) adversely affect
in any material respect the interests of the Holders of any Class of
Certificates in a manner other than as described in (i), without the consent
of the Holders of Certificates of such Class evidencing [66]% or more of the
Voting Rights of such Class, (iii) reduce the aforesaid percentages of
Certificates the Holders of which are required to consent to any such
amendment without the consent of the Holders of all such Certificates then
outstanding, or (iv) adversely affect in any material respect the rights and
interests of the Class [AF-5B] Insurer in any of the provisions of this
Agreement without its consent, which consent shall not be unreasonably
withheld: (I) the definitions of "Class [AF-5B] Premium" and "Reimbursement
Amount" in Article I, (II) the priority of payments to the Class [AF-5B]
Insurer pursuant to Sections 4.04(a), (b) and (d) and (III) Sections 4.06,
10.01, and 10.12.

            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 [AF-5B] Insurer 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.

            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

                                     179
<PAGE>

properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Master Servicer at its expense.

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

            Section 10.03 Governing Law.
                          ______________

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

            Section 10.04 Intention of Parties.
                          _____________________

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

            The Depositor for the benefit of the Certificateholders and the
NIM Insurer 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.

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

      report (in form and substance reasonably satisfactory to the Depositor)

      involving such Person and that are backed by the same asset type backing
      the Certificates, such report shall include such a statement to that

                  (4) Each of the Trustee and the Co-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

      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. 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 a certification to
      the Certifying Person pursuant to this Section 11.07 with respect to the
      period of time it was subject to this Agreement or provided services

elements of the Servicing Criteria other than those specified by the Master
Servicer, the Trustee or the Co-Trustee, as applicable, pursuant to Section

assessments of compliance provided by each Subcontractor identified pursuant
to clause (ii) of this paragraph.

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

exceptions) the Co-Trustee has received:

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

of the documents contained in each Mortgage File of any of the Mortgage Loans

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 _________, 200_ (the "Agreement"), by and among [CWHEQ, Inc.], as
depositor (the "Depositor"), [Countrywide Home Loans, Inc.], as a Seller,
[Park Monaco Inc.], as a Seller, [Park Sienna LLC], as a Seller, [Countrywide
Home Loans Servicing LP], as Master Servicer, the undersigned, as Trustee,
____________________________, as Co-Trustee and __________________, as
Trustee. Capitalized terms used, but not defined herein or in Exhibit 1
hereto, shall have the meanings ascribed to such terms in the Agreement. The
Transferee has authorized the undersigned to make this affidavit on behalf of
the Transferee.

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

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

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

                                     I-1-1

<PAGE>

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

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

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

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

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

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

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

                              Certain Definitions

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

            "Permitted Transferee": Any person other than (i) the United
States, any State or political subdivision thereof, or any agency or
instrumentality of any of the foregoing, (ii) a foreign government,
International Organization or any agency or instrumentality of either of the
foregoing, (iii) an organization (except certain farmers' cooperatives
described in section 521 of the Code) that is exempt from tax imposed by
Chapter 1 of the Code (including the tax imposed by section 511 of the Code on
unrelated business taxable income) on any excess inclusions (as defined in
section 860E(c)(1) of the Code) with respect to any Class A-R Certificate,
(iv) rural electric and telephone cooperatives described in section
1381(a)(2)(C) of the Code, (v) an "electing large partnership" as defined in
section 775 of the Code, (vi) a Person that is not a citizen or resident of
the United States, a corporation, partnership, or other entity (treated as a
corporation or a partnership for federal income tax purposes) created or
organized in or under the laws of the United States, any state thereof or the
District of Columbia, or an estate whose income from sources without the
United States is includible in gross income for United States federal income
tax purposes regardless of its connection with the conduct of a trade or
business within the United States, or a trust if a court within the United
States is able to exercise primary supervision over the administration of the
trust and one or more United States persons have authority to control all
substantial decisions of the trustor unless such Person has furnished the
transferor and the Trustee with a duly completed Internal Revenue Service Form
W-8ECI, and (vii) any other Person so designated by the Trustee based upon an
Opinion of Counsel that the Transfer of an Ownership Interest in a Class A-R
Certificate to such Person may cause any REMIC formed hereunder to fail to
qualify as a REMIC at any time that any Certificates are Outstanding. The
terms "United States," "State" and "International Organization" shall have the
meanings set forth in section 7701 of the Code or successor provisions. A
corporation will not be treated as an instrumentality of the United States or
of any State or political subdivision thereof for these purposes if all of its
activities are subject to tax and, with the exception of the Federal Home Loan
Mortgage Corporation, a majority of its board of directors is not selected by
such government unit.

beneficiary thereof), unincorporated organization or government or any agency
or political subdivision thereof.

Ownership Interest in a Certificate, including the acquisition of a
Certificate by the Depositor.

                       Section 5.02(c) of the Agreement

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

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

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

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

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

                                     I-1-5

<PAGE>

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

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

              statements made herein because one or more sales to the Buyer
              may be in reliance on Rule 144A.

indicated on the attached schedule, based upon:

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

                  THE CERTIFICATES AND TRANSFERS OF INTERESTS

         Section 3.01. The Certificates. The Ownership Certificate shall
initially be issued as a single certificate in definitive, fully registered
form and shall initially be registered in the name of the applicable Initial
Holder. No Ownership Certificate shall be issued in authorized denominations
of less than a 100% Percentage Interest in such Certificate. The Certificates
shall be executed on behalf of the Trust by manual or facsimile signature of
an Authorized Officer of the Owner Trustee and authenticated in the manner
provided in Section 3.02. Each Certificate bearing the manual signatures of
individuals who were, at the time when such signatures shall have been
affixed, authorized to sign on behalf of the Trust, shall be validly issued
and entitled to the benefit of this Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
authentication and delivery of each such Certificate or did not hold such
offices at the date of authentication and delivery of each such Certificate. A
Person shall become a Certificateholder and shall be entitled to the rights
and subject to the obligations of a Certificateholder hereunder upon such
Person's acceptance of a Certificate duly registered in such Person's name
pursuant to Section 3.03.

         Section 3.02. Execution, Authentication and Delivery of the
Certificates.

         Concurrently with the sale of the Collateral to the Trust pursuant to
the Sale and Servicing Agreement, the Owner Trustee shall cause the
Certificates issued hereunder to be executed and authenticated on behalf of
the Trust and delivered to the Initial Holder, without further corporate
action by the Depositor. No Certificate shall entitle its Holder to any
benefit under this Agreement or be valid for any purpose unless there shall
appear on such Certificate a

                                      9
<PAGE>

certificate of authentication substantially in the form set forth as part of
Exhibit A hereto, executed by the Owner Trustee or the Certificate Registrar,
as the Owner Trustee's authenticating agent, by manual signature; such
authentication shall constitute conclusive evidence that such Certificate
shall have been duly authenticated and delivered hereunder. All Certificates
shall be dated the date of their authentication.

         Section 3.03. Registration of and Limitations on Transfers and
Exchanges of the Certificates. The Certificate Registrar shall keep or cause
to be kept, at the office or agency maintained pursuant to Section 3.08, a
Certificate Register in which, subject to such reasonable regulations as it
may prescribe, the Certificate Registrar shall provide for the registration of
the Certificates and of transfers and exchanges of the Certificates as set
forth herein, provided, however, that no Ownership Certificate shall be issued
in any such transfer and exchange representing less than a 100% Percentage
Interest in such Certificate; and provided, further, that no Ownership
Certificate shall be issued in any such transfer and exchange except in
accordance with the provisions and conditions set forth below in this Section
3.03. The Trust Administrator shall be the initial Certificate Registrar. If
the Certificate Registrar resigns or is removed, the Owner Trustee, with the
consent of the Depositor, shall appoint a successor Certificate Registrar.

         Subject to satisfaction of the conditions set forth below, upon
surrender for registration of transfer of a Certificate at the office or
agency maintained pursuant to Section 3.08, the Owner Trustee shall execute,
authenticate and deliver (or cause the Trust Administrator as its
authenticating agent to authenticate and deliver), in the name of the
designated transferee, a new Certificate evidencing the Percentage Interest of
the Certificate so surrendered and dated the date of authentication by the
Owner Trustee or the Certificate Registrar.

         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 Owner Trustee and the Certificate Registrar duly
executed by each Certificateholder or such Certificateholder's attorney duly
authorized in writing. Each Certificate surrendered for registration of
transfer or exchange shall be cancelled and subsequently disposed of by the
Certificate Registrar in accordance with its customary practice.

         No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Owner Trustee or the Certificate Registrar
may require payment of a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any transfer or exchange of a
Certificate or any other expense arising as a result of any registration of
transfer or exchange.

         The preceding provisions of this Section notwithstanding, the Owner
Trustee shall not make and the Certificate Registrar shall not register
transfer or exchanges of a Certificate for a period of 15 days preceding the
due date for any payment with respect to such Certificate.

         No transfer of a Certificate shall be made unless such transfer is
exempt from the registration requirements of the Securities Act and any
applicable state securities laws or is made in accordance with said Act and
laws. Except in the case of an initial transfer to an Initial Holder, in the
event of any such transfer, the Certificate Registrar or the Depositor shall
prior to such transfer require the transferee to execute (i) an investment
letter (in the form attached hereto

                                      10
<PAGE>

as Exhibit D-1) certifying to the Trust, the Owner Trustee, the Trust
Administrator, the Certificate Registrar and the Depositor that such
transferee is a "qualified institutional buyer" under Rule 144A under the
Securities Act, or (ii) an investment letter (in the form attached hereto as
Exhibit D-2) certifying to the Trust, the Owner Trustee, the Trust
Administrator, the Certificate Registrar and the Depositor that such
transferee is an "accredited investor" (as defined in Rule 501(a)(1), (2), (3)
or (7) of the Securities Act), and any expense associated with the preparation
and execution of any such investment letter shall not be an expense of the
Trust, the Owner Trustee, the Trust Administrator, the Certificate Registrar
or the Depositor. A Certificateholder desiring to effect the transfer of a
Certificate shall, and does hereby agree to, indemnify the Trust, the Owner
Trustee, the Trust Administrator, the Certificate Registrar and the Depositor
against any and all liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

         Except in the case of an initial transfer to an Initial Holder, no
transfer of a Certificate shall be made unless the Certificate Registrar shall
have received a representation letter (in the form attached hereto as Exhibit
D-1 or D-2) from the proposed transferee of such Certificate to the effect
that such proposed transferee is not an employee benefit plan or other
retirement arrangement subject to Section 406 of ERISA, or Section 4975 of the
Code or any substantially similar applicable law, or a Person acting on behalf
of or using the assets of any such plan, which representation letter shall not
be an expense of the Trust, the Owner Trustee, the Trust Administrator, the
Certificate Registrar or the Depositor.

         Prior to and as a condition of the registration of any transfer, sale
or other disposition of the Ownership Certificate, the Initial Holder of the
Ownership Certificate and each Prospective Holder of an Ownership Certificate
shall represent and warrant in writing, in the case of each Initial Holder, in
substantially the form set forth in Exhibit E hereto, and in the case of each
Prospective Holder, in substantially the form set forth in Exhibit F hereto,
to the Owner Trustee, the Trust Administrator and the Certificate Registrar
and any of their respective successors that:

               (i) Such Person is duly authorized to purchase the Ownership
         Certificate and its purchase of investments having the
         characteristics of the Ownership Certificate is authorized under,
         and not directly or indirectly in contravention of, any law,
         charter, trust instrument or other operative document, investment
         guidelines or list of permissible or impermissible investments that
         is applicable to the investor;

              (ii) Such Person understands that each holder of an Ownership
         Certificate, by virtue of its acceptance thereof, assents to the
         terms, provisions and conditions of the Agreement; and

             (iii) [Such Person is a REIT, a Qualified REIT Subsidiary or a
         Disregarded Entity.]

         The Owner Trustee shall cause each Certificate to contain a legend,
substantially similar to the applicable legends provided in Exhibit A hereto,
stating that transfer of such Certificate is subject to certain restrictions
and referring prospective purchasers of the Certificates to this Section 3.03
with respect to such restrictions.

                                      11

         Section 3.04. Lost, Stolen, Mutilated or Destroyed Certificate. If
(a) a mutilated Certificate is surrendered to the Certificate Registrar, or
(b) the Certificate Registrar receives evidence to its satisfaction that a
Certificate has been destroyed, lost or stolen, and there is delivered to the
Certificate Registrar proof of ownership satisfactory to the Certificate
Registrar, together with such security or indemnity as required by the
Certificate Registrar and the Owner Trustee to save each of them harmless,
then in the absence of notice to the Certificate Registrar or the Owner
Trustee that such Certificate has been acquired by a protected purchaser, the
Owner Trustee shall execute on behalf of the Trust, and the Owner Trustee or
the Certificate Registrar shall authenticate and deliver, in exchange for or
in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like tenor and Percentage Interest. In connection with the
issuance of any new Certificate under this Section 3.04, the Owner Trustee or
the Certificate Registrar may require the payment of a sum sufficient to cover
any expenses of the Owner Trustee or the Certificate Registrar (including any
fees and expenses of counsel) and any tax or other governmental charge that
may be imposed in connection therewith. Any duplicate Certificate issued
pursuant to this Section 3.04 shall constitute conclusive evidence of
ownership in the Trust, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

         Section 3.05. Persons Deemed Certificateholders. Prior to due
presentation of a Certificate for registration of transfer, the Owner Trustee,
the Certificate Registrar or any Certificate Paying Agent may treat any
Certificateholder as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.02 and for all other purposes
whatsoever, and none of the Trust, the Owner Trustee, the Certificate
Registrar or any Certificate Paying Agent shall be bound by any notice to the
contrary.

         Section 3.06. Access to List of Certificateholders' Names and

to the extent consistent with the limited purpose of the Trust. Such direction
may be exercised at any time by written instruction of the Ownership
Certificate Holder pursuant to this Article V.

         (b) Notwithstanding the foregoing, the Owner Trustee shall not be
required to take any action hereunder or under any Operative Agreement if the

or is otherwise contrary to law.

         (c) Whenever the Owner Trustee is unable to decide between
alternative courses of action permitted or required by the terms of this
Agreement or under any other Operative Agreement, or in the event that the
Owner Trustee is unsure as to the application of any provision of this
Agreement or any other Operative Agreement or any such provision is ambiguous
as to its application, or is, or appears to be, in conflict with any other
applicable provision, or in the event that this Agreement permits any
determination by the Owner Trustee or is silent or is incomplete as to the
course of action that the Owner Trustee is required to take with respect to a
particular set of facts, the Owner Trustee may promptly give notice (in such
form as shall be appropriate under the circumstances) to the Ownership
Certificate Holder requesting instruction as to the course of action to be
adopted, and to the extent the Owner Trustee acts in good faith in accordance
with any written instruction of the Ownership Certificate Holder, the Owner
Trustee shall not be liable on account of such action to any Person. If the
Owner Trustee shall not have received appropriate instruction within 10 days
of such notice (or within such shorter period of time as reasonably may be
specified in such notice or may be necessary under the circumstances) it may,
but shall be under no duty to, take or refrain from taking such action not

conferred upon the Owner Trustee pursuant to this Agreement, and (ii) in
accordance with any document or instruction delivered to the Owner Trustee
pursuant to Section 5.03; and no implied duties or obligations shall be read

shall have no duty or obligation to execute, file or deliver, or cause the
preparation, filing or delivery by other persons of, any such documents,
reports, filings, instruments, certificates or opinions as it shall be the

         the court before which any proceeding therefor may be brought;

              (ii)   the Bank has no reason to believe that anyone authorized to
         act on its behalf has offered any interest in and to the Trust for
         sale to, or solicited any offer to acquire any of the same from,
         anyone;

              (iii)  the execution, delivery and performance by the Bank,
         either in its individual capacity or as Owner Trustee, as the case
         may be, of the Operative Agreements will not result in any violation
         of, or be in any conflict with, or constitute a default under any of
         the provisions of any indenture, mortgage, chattel mortgage, deed of
         trust, conditional sales contract, lease, note or bond purchase
         agreement, license,

                                      21
<PAGE>

         judgment, order or other agreement to which the Bank is a party
         or by which it or any of its properties is bound;

              (iv)   the execution and delivery by the Bank of this Agreement,
         and the performance of its duties as Owner Trustee hereunder, do not
         require the consent or approval of, the giving of notice to, or the
         registration with, or the taking of any other action with respect to,
         any governmental authority or agency of the State of Delaware (except
         as may be required by the Delaware Trust Statute); and

              (v)    there are no pending or, to the best of its knowledge,
         threatened actions or proceedings against the Bank before any court,
         administrative agency or tribunal which, if determined adversely to
         it, would materially and adversely affect its ability, either in its
         individual capacity or as Owner Trustee, as the case may be, to
         perform its obligations under this Agreement or the Operative
         Agreements.

        (b)      _____________________, as Trust Administrator, hereby
represents and warrants to the Depositor, for the benefit of each
Certificateholder, that:

              (i)    it is a _______________________ duly organized and validly
         existing in good standing under the laws of the ______________, and
         has the power and authority to execute, deliver and perform its
         obligations under this Agreement and, assuming the due authorization,
         execution and delivery hereof by the other parties hereto, this
         Agreement constitutes a legal, valid and binding obligation of the
         Trust Administrator, enforceable against the Trust Administrator in
         accordance with its terms, 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;

              (ii)   it has taken all action necessary to authorize the
         execution and delivery by it of this Agreement, and this Agreement
         will be executed and delivered by one of its officers who is duly
         authorized to execute and deliver this Agreement on its behalf; and

              (iii)  neither the execution nor the delivery by it of this
         Agreement nor the consummation by it of the transactions contemplated
         hereby nor compliance by it with any of the terms or provisions
         hereof will contravene any federal, governmental rule or regulation
         governing the banking or trust powers of the Trust Administrator or
         any judgment or order binding on it, or constitute any default under
         its charter documents or by-laws or any indenture, mortgage,
         contract, agreement or instrument to which it is a party or by which
         any of its properties may be bound.

         Section 6.05. Reliance; Advice of Counsel.

         (a) Except as provided in Section 6.01, the Owner Trustee shall incur
no liability to anyone in acting upon any signature, instrument, notice,
resolution, request, consent, order, certificate, report, opinion, bond or
other document or paper believed by it to be genuine and believed by it to be
signed by the proper party or parties. The Owner Trustee may accept a

                                      22
<PAGE>

certified copy of a resolution of the board of directors or other governing
body of any corporate or partnership entity as conclusive evidence that such
resolution has been duly adopted by such body and that the same is in full
force and effect. As to any fact or matter the manner of ascertainment of
which is not specifically prescribed herein, the Owner Trustee may for all
purposes hereof rely on a certificate, signed by the president or any vice
president (or the general partner, in the case of a partnership) and by the
treasurer or any assistant treasurer or the secretary or any assistant
secretary of the relevant party, as to such fact or matter, and such
certificate shall constitute full protection to the Owner Trustee for any
action taken or omitted to be taken by it in good faith in reliance thereon.

         (b) In its exercise or administration of the trusts and powers
hereunder, including its obligations under Section 5.02(b), and in the
performance of its duties and obligations under this Agreement or the other
Operative Agreements, the Owner Trustee may employ agents and attorneys and
enter into agreements (including the Sale and Servicing Agreement) with any of
them, and the Owner Trustee shall not be answerable for the default or
misconduct of any such agents or attorneys if such agents or attorneys shall
have been selected by the Owner Trustee with reasonable care. If, and to the
extent, the Seller shall have failed to reimburse the Owner Trustee for all
reasonable expenses and indemnities incurred pursuant to this Section 6.05(b),
as provided in Section 7.01 and Section 7.02, the Owner Trustee may seek
reimbursement therefor from the Trust Estate.

         (c) In the administration of the trusts and performance of its duties
hereunder, the Owner Trustee may consult with counsel, accountants and other
skilled Persons to be selected and employed by it, and the Owner Trustee shall
not be liable for anything done, suffered or omitted in good faith by it in
accordance with the reasonable advice or opinion of any such counsel,
accountants or other skilled Persons. If, and to the extent, the Seller shall
have failed to reimburse the Owner Trustee for all reasonable expenses and
indemnities incurred pursuant to this Section 6.05(c), as provided in Section
7.01 and Section 7.02, the Owner Trustee may seek reimbursement therefor from
the Trust Estate.

         Section 6.06. Not Acting in Individual Capacity. Except as provided
in this Article VI, in accepting the trusts hereby created the Owner Trustee
acts solely as trustee hereunder and not in its individual capacity, and all
persons having any claim against the Owner Trustee by reason of the
transactions contemplated by the Operative Agreements shall look only to the
Trust Estate for payment or satisfaction thereof.

         Section 6.07. Owner Trustee Not Liable for Certificates or
Collateral. The recitals contained herein and in the Certificates (other than
the signatures and countersignatures of the Owner Trustee on the Certificates)
shall be taken as the statements of the Depositor, and the Owner Trustee
assumes no responsibility for the correctness thereof. The Owner Trustee makes
no representations as to the validity or sufficiency of this Agreement, of any
Operative Agreement or of the Certificates (other than the signatures and
countersignatures of the Owner Trustee on the Certificates) or the Notes, or
of any Collateral or related documents. The Owner Trustee shall at no time
have any responsibility or liability for or with respect to the legality,
validity and enforceability of any Collateral, or the perfection and priority
of any security interest created by any Collateral or the maintenance of any
such perfection and priority, or for or with respect to the sufficiency of the
Trust Estate or its ability to generate the payments to be

                                      23
<PAGE>

distributed to Certificateholders under this Agreement or the Noteholders
under the Indenture, including, without limitation: the existence, condition
and ownership of any Collateral; the existence and enforceability of any
insurance thereon; the existence and contents of any Collateral on any
computer or other record thereof; the validity of the assignment of any
Collateral to the Trust or of any intervening assignment; the completeness of
any Collateral; the performance or enforcement of any Collateral; the
compliance by the Depositor with any warranty or representation made under any
Operative Agreements or in any related document or the accuracy of any such
warranty or representation or any action of the Trust Administrator or the
Indenture Trustee taken in the name of the Owner Trustee.

         Section 6.08. Owner Trustee May Own Notes. The Owner Trustee in its
individual capacity may become an owner or pledgee of Notes and may deal with
the Depositor, the Trust Administrator and the Indenture Trustee in banking
transactions with the same rights as it would have if it were not Owner
Trustee.

         Section 6.09. Licenses. The Depositor shall cause the Trust to use
its best efforts to obtain and maintain the effectiveness of any licenses
required in connection with this Agreement and the other Operative Agreements
and the transactions contemplated hereby and thereby until such time as the
Trust shall terminate in accordance with the terms hereof. It shall be the
duty of the Owner Trustee to cooperate with the Depositor with respect to such
matters.

         Section 6.10. Doing Business in Other Jurisdictions. Notwithstanding
anything contained herein to the contrary, neither the Bank nor the Owner
Trustee shall be required to take any action in any jurisdiction other than in
the State of Delaware if the taking of such action will (i) require the
consent or approval or authorization or order of or the giving of notice to,
or the registration with or the taking of any other action in respect of, any
state or other governmental authority or agency of any jurisdiction other than
the State of Delaware; (ii) result in any fee, tax or other governmental
charge under the laws of any jurisdiction or any political subdivisions
thereof in existence on the date hereof other than the State of Delaware
becoming payable by the Bank or the Owner Trustee; or (iii) subject the Bank
or the Owner Trustee to personal jurisdiction in any jurisdiction other than
the State of Delaware for causes of action arising from acts unrelated to the
consummation of the transactions by the Bank or the Owner Trustee, as the case
may be, contemplated hereby. The Owner Trustee shall be entitled to obtain
advice of counsel (which advice shall be an expense of the Trust) to determine
whether any action required to be taken pursuant to this Agreement results in
the consequences described in clauses (i), (ii) and (iii) of the preceding
sentence. In the event that such counsel advises the Owner Trustee that such
action will result in such consequences, the Owner Trustee will appoint a
co-trustee pursuant to Section 9.05 hereof to proceed with such action.

         Section 6.11. Sarbanes-Oxley Act Certification.

         Notwithstanding anything to the contrary herein or in any Operative
Agreement, the Owner Trustee shall not be required to execute, deliver or
certify on behalf of the Trust or any other Person any filings, certificates,
affidavits or other instruments in connection with certifications required
under the Sarbanes-Oxley Act of 2002.

                                 ARTICLE VII
                       INDEMNIFICATION AND COMPENSATION

         Section 7.01. Trust Expenses. The Seller shall pay the organizational
expenses of the Trust as they may arise or shall, upon the request of the
Owner Trustee, promptly reimburse the Owner Trustee for any such expenses paid
by the Owner Trustee in connection therewith. The Seller shall also pay (or
reimburse the Bank for) all reasonable expenses of the Owner Trustee
hereunder, including, without limitation, the reasonable compensation,
expenses and disbursements of such agents, representatives, experts and
counsel as the Owner Trustee may employ in connection with the exercise and
performance of its rights and duties under the Operative Agreements.

         Section 7.02. Indemnification. The Seller agrees to assume liability
for, and indemnify the Bank and its successors, assigns, officers, directors,
agents and servants, against and from, any and all liabilities, obligations,
losses, damages, taxes, claims, actions, suits, costs, expenses and
disbursements (including reasonable legal fees and expenses) of any kind and
nature whatsoever (collectively, "Expenses") which may be imposed on, incurred
by or asserted at any time against the Bank (whether or not indemnified
against by other parties) in any way relating to or arising out of this
Agreement, any Operative Agreement, the Collateral, the administration of the
Trust Estate or the action or inaction of the Owner Trustee hereunder, except
only that the Seller shall not be required to indemnify the Bank for Expenses
arising or resulting from any of the matters described in the third sentence
of Section 6.01. The indemnities contained in this Section 7.02 shall survive
the resignation or termination of the Owner Trustee or the termination of this
Agreement. In the event of any claim, action or proceeding for which indemnity
will be sought pursuant to this Section, the Owner Trustee's choice of legal
counsel shall be subject to the approval of the Seller, which approval shall
not be unreasonably withheld.

         Section 7.03. Compensation. The Bank shall receive as compensation
for its services hereunder such fees as are set forth in the Fee Letter
Agreement between the Bank and the Seller. The Trust Administrator shall pay
the annual fee of the Owner Trustee, and the Seller shall pay the initial fee
of the Owner Trustee.

         Section 7.04. Lien on Trust Estate. The Bank shall have a lien on the
Trust Estate for any compensation or indemnity due hereunder, such lien to be
subject only to prior liens of the Indenture. The Bank shall not bring any
proceedings to foreclose on such lien if and to the extent the Trust Estate is
subject to the lien of the Indenture. Any amount paid to the Owner Trustee
pursuant to this Article VII shall be deemed not to be part of the Trust
Estate immediately after such payment.

                                 ARTICLE VIII
                           TERMINATION OF AGREEMENT

         Section 8.01. Termination of Agreement.

         (a) This Agreement (other than Article VII) shall terminate and the
trusts created hereby shall dissolve and terminate and the Trust Estate shall,
subject to the Indenture and Sections 4.01 and 7.04 and Section 3808 of the
Delaware Trust Statute, be distributed to the

                                      25
<PAGE>

Certificateholders, and this Agreement shall be of no further force or
effect, upon the earlier of (i) the full payment of principal and interest
due on all Classes of the Notes; and (ii) the sale or other final disposition
by the Indenture Trustee or the Owner Trustee, as the case may be, of all the
Trust Estate and the final distribution by the Trust Administrator or the
Owner Trustee, as the case may be, of all moneys or other property or proceeds
of the Trust Estate in accordance with the terms of the Indenture, the Sale
and Servicing Agreement and Section 4.02. The bankruptcy, liquidation or
dissolution of any Certificateholder shall not operate to terminate this
Agreement, nor entitle such Certificateholder's legal representatives to claim
an accounting or to take any action or proceeding in any court for a partition
or winding up of the Trust Estate, nor otherwise affect the rights,
obligations and liabilities of the parties hereto.

         (b) Except as provided in Section 8.01(a), none of the Depositor or
any Certificateholder shall be entitled to revoke or terminate the Trust
established hereunder.

         (c) Notice of any termination of the Trust, specifying the Payment
Date upon which Certificateholders shall surrender their Certificates to the
Certificate Paying Agent for payment of the final distribution and
cancellation, shall be given by the Certificate Paying Agent by letter to the
Certificateholders and the Rating Agencies mailed within five Business Days of
receipt of notice of the final payment on the Notes pursuant to the Sale and
Servicing Agreement, stating (i) the Payment Date upon or with respect to
which final payment of the Certificates shall be made upon presentation and
surrender of the Certificates at the office of the Certificate Paying Agent
therein designated, (ii) the amount of any such final payment and (iii) that
the Record Date otherwise applicable to such Payment Date is not applicable,
payments being made only upon presentation and surrender of the Certificates
at the office of the Certificate Paying Agent therein specified. The
Certificate Paying Agent shall give such notice to the Owner Trustee and the
Certificate Registrar at the time such notice is given to the
Certificateholders. Upon presentation and surrender of the Certificates, the
Certificate Paying Agent shall cause to be distributed to the applicable
Certificateholder amounts distributable on such Payment Date pursuant to
Section 5.08 and Section 6.02 of the Sale and Servicing Agreement.

         (d) Upon the winding up of the Trust and its termination, the Owner
Trustee shall upon the written request of the Depositor cause the Certificate
of Trust to be cancelled by filing a certificate of cancellation with the
Secretary of State in accordance with the provisions of Section 3810 of the
Delaware Trust Statute.

                                  ARTICLE IX
            SUCCESSOR OWNER TRUSTEES AND ADDITIONAL OWNER TRUSTEES

         Section 9.01. Eligibility Requirements for Owner Trustee. The Owner
Trustee shall at all times be a corporation satisfying the provisions of
Section 3807(a) of the Delaware Trust Statute; authorized to exercise
corporate powers; having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by Federal or state
authorities; and having (or having a parent which has) a short-term debt
rating of at least "A-1" or the equivalent by, or which is otherwise
acceptable to, the Rating Agencies. If such corporation shall publish reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purpose of this
Section, the combined capital and surplus of such corporation shall be deemed
to be its combined capital and surplus as set

                                      26
<PAGE>

forth in its most recent report of condition so published. In case at
any time the Owner Trustee shall cease to be eligible in accordance with the
provisions of this Section, the Owner Trustee shall resign immediately in the
manner and with the effect specified in Section 9.02.

         Section 9.02. Resignation or Removal of Owner Trustee. The Owner
Trustee may at any time resign and be discharged from the trusts hereby
created by giving 30 days' prior written notice thereof to the Depositor, the
Certificateholders and the Indenture 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 Owner 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 Owner Trustee. Upon receiving such notice of
resignation, the Depositor shall promptly appoint (subject to the consent of
the Certificateholders, which consent shall not be unreasonably withheld) a
successor Owner Trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the resigning Owner Trustee and one copy to
the successor Owner Trustee. If no successor Owner Trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of
such notice of resignation, the resigning Owner Trustee may petition any court
of competent jurisdiction for the appointment of a successor Owner Trustee.

         If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 9.01 and shall fail to resign after
written request therefor by the Depositor, or if at any time the Owner Trustee
shall be legally unable to act, or shall be adjudged bankrupt or insolvent, or
a receiver of the Owner Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Owner Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation or the Owner Trustee shall fail to fulfill its obligations under
Section 9.02 with respect to notice to the Depositor or Article XI of the Sale
and Servicing Agreement, 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), then the
Depositor may remove the Owner Trustee. If the Depositor shall remove the
Owner Trustee under the authority of the immediately preceding sentence, the
Depositor shall promptly appoint (subject to the consent of the
Certificateholders, which consent shall not be unreasonably withheld) a
successor Owner Trustee by written instrument in duplicate, one copy of which
instrument shall be delivered to the outgoing Owner Trustee so removed and one
copy to the successor Owner Trustee and payment of all fees owed to the
outgoing Owner Trustee.

         Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section
shall not become effective until acceptance of appointment by the successor
Owner Trustee pursuant to Section 9.03 and payment of all fees and expenses
owed to the outgoing Owner Trustee. The Trust Administrator shall provide
notice of such resignation or removal of the Owner Trustee to the Rating
Agencies.

         Section 9.03. Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 9.02 shall execute, acknowledge and deliver to
the Trust Administrator and to its predecessor Owner Trustee an instrument
accepting such appointment under this

                                      27
<PAGE>

Agreement, and thereupon the resignation or removal of the predecessor Owner
Trustee shall become effective and such successor Owner Trustee without any
further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties, and obligations of its predecessor under this
Agreement, with like effect as if originally named as Owner Trustee. The
predecessor Owner Trustee shall upon payment of its fees and expenses deliver
to the successor Owner Trustee all documents and statements and monies held by
it under this Agreement; and the Trust Administrator and the predecessor Owner
Trustee shall execute and deliver such instruments and do such other things as
may reasonably be required for fully and certainly vesting and confirming in
the successor Owner Trustee all such rights, powers, duties, and obligations.

         No successor Owner Trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor Owner
Trustee shall be eligible pursuant to Section 9.01.

         Upon acceptance of appointment by a successor Owner Trustee pursuant
to this Section, the Trust Administrator shall mail notice of the successor of
such Owner Trustee to all Certificateholders, the Indenture Trustee, the
Noteholders and the Rating Agencies. If the Trust Administrator fails to mail
such notice within 10 days after acceptance of appointment by the successor
Owner Trustee, the successor Owner Trustee shall cause such notice to be
mailed at the expense of the Trust Administrator.

         Section 9.04. Merger or Consolidation of Owner Trustee. Any Person
into which the Owner Trustee may be merged or converted or with which it may
be consolidated or any Person resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, provided
such Person shall be eligible pursuant to Section 9.01, without the execution
or filing of any instrument or any 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 Owner Trustee, the Owner Trustee shall provide (x)
written notice to the Depositor and the Master Servicer 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 successor Owner Trustee.

         Section 9.05. 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 Estate or any Collateral may at the time be located, and for
the purpose of performing certain duties and obligations of the Owner Trustee
with respect to the Trust and the Certificates under the Sale and Servicing
Agreement, the Owner Trustee shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Owner
Trustee to act as co-trustee, jointly with the Owner Trustee, or separate
trustee or separate trustees, of all or any part of the Trust Estate, and to
vest in such Person, in such capacity, such title to the Trust, or any part
thereof, and,

                                      28
<PAGE>

subject to the other provisions of this Section, such powers, duties,
obligations, rights and trusts as the Owner Trustee may consider necessary or
desirable. No co-trustee or separate trustee under this Agreement shall be
required to meet the terms of eligibility as a successor trustee pursuant to
Section 9.01 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 9.03.

         The Owner Trustee hereby appoints the Trust Administrator for the
purpose of establishing and maintaining the Collection Account and making the
distributions therefrom to the Persons entitled thereto pursuant to Section
5.08 and Section 6.02 of the Sale and Servicing Agreement.

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

         (a) all rights, powers, duties and obligations conferred or imposed
upon the Owner Trustee shall be conferred upon and exercised or performed by
the Owner 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 Owner 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, the Owner 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 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 Owner Trustee;

         (b) no trustee under this Agreement shall be personally liable by
reason of any act or omission of any other trustee under this Agreement; and

         (c) the Trust Administrator and the Owner Trustee acting jointly 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 Owner Trustee shall
be deemed to have been given to the separate trustees and co-trustees, as if
given to each of them. Every instrument appointing any separate trustee or
co-trustee, other than this Agreement, shall refer to this Agreement and to
the conditions of this Article. Each separate trustee and co-trustee, upon its
acceptance of appointment, shall be vested with the estates specified in its
instrument of appointment, either jointly with the Owner 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
Owner Trustee. Each such instrument shall be filed with the Owner Trustee and
a copy thereof given to the Trust Administrator.

         Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as 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 Owner Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                                 MISCELLANEOUS

         Section 10.01. Supplements and Amendments. This Agreement may be
amended by the Depositor, the Trust Administrator and the Owner Trustee, with
the consent of the Certificateholder and with prior written notice to the
Rating Agencies, but without the consent of any of the Noteholders or the
Indenture Trustee, (i) to cure any ambiguity, (ii) to conform the provisions
of this Agreement to the information contained in the Prospectus or to correct
or supplement any provision herein, (iii) to make any other provision with
respect to matters or questions arising under this Agreement or (iv) to add,
delete, or amend any provision in order to comply with any requirements
imposed by the Code, ERISA and their related regulations; provided, however,
that such action shall not, as evidenced by an Opinion of Counsel, adversely
affect in any material respect the interests of any Noteholder or
Certificateholder or adversely affect the tax status of the Trust. An
amendment shall not be deemed to adversely affect in any material respect the
interests of any Noteholder or Certificateholder and no opinion referred to in
the preceding proviso shall be required to be delivered if the Person
requesting the amendment obtains a letter from each Rating Agencies stating
that the amendment would not result in the downgrading or withdrawal of the
respective ratings then assigned to each applicable Class of Notes and
Certificates. Notwithstanding the preceding sentence, an opinion shall be
required with respect to tax matters as set forth in this paragraph.

         This Agreement may also be amended from time to time by the
Depositor, the Trust Administrator and the Owner Trustee, with the prior
written consent of the Rating Agencies, the holders of Notes evidencing more
than 66?% of the Outstanding Balance of the Notes and the Certificateholder,

eliminating any of the provisions of this Agreement or modifying in any manner
the rights of Certificateholders; provided, however, that no such amendment
shall, as evidenced by an Opinion of Counsel, adversely affect the tax status
of the Trust; and provided, further, that no such amendment shall (a) increase
or reduce in any manner the amount of, or delay the timing of, collections of
payments on the Collateral or payments that shall be required to be made for
the benefit of the Noteholders or any Certificateholder or (b) reduce the
aforesaid percentage of the Outstanding Balance of the Notes required to
consent to or to waive the requirement for any Certificateholder to consent to
any such amendment, in either case of clause (a) or (b) without the consent of
the holders of all the outstanding Notes and each Certificateholder.

         Notwithstanding the foregoing, no provision of Sections 2.03 or 5.06
hereof may be amended in any manner unless (i) 100% of the Outstanding Balance
of the Noteholders have consented in writing thereto, (ii) the Rating Agencies
have consent in writing thereto or (iii) the Notes have been paid in full and
the Indenture has been discharged.

         Promptly after the execution of any such amendment or consent, the
Trust Administrator shall furnish written notification of the substance of
such amendment or consent to each Certificateholder, the Indenture Trustee and
the Rating Agencies.

         It shall not be necessary for the consent of the Certificateholders
or the Noteholders pursuant to this Section 10.01 to approve the particular
form of any proposed amendment or consent, but it shall be sufficient if such
consent shall approve the substance thereof. The
