            This Pooling and Servicing Agreement is dated as of December 21,
2006 (the "Agreement"), among WELLS FARGO ASSET SECURITIES CORPORATION, as
depositor (the "Depositor"), WELLS FARGO BANK, N.A., as servicer (the
"Servicer"), WELLS FARGO BANK, N.A., as securities administrator (the
"Securities Administrator"), and HSBC BANK USA, NATIONAL ASSOCIATION, as trustee
(the "Trustee").

                              PRELIMINARY STATEMENT

            The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple Classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust Fund created hereunder. The Certificates will consist of sixteen
Classes of Certificates, designated as (i) the Class A-1, Class A-2 and Class
A-3 Certificates, (ii) the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5
and Class M-6, (iii) the Class B-1, Class B-2, Class B-3 and Class B-4
Certificates, (iv) the Class CE Certificates, (v) the Class P Certificates and
(vi) the Class R Certificate.

            The Trustee shall elect that five segregated asset pools within the
Trust Fund (exclusive of (i) the Prepayment Penalties, the Servicer Prepayment
Penalty Payment Amounts and the Originator Prepayment Penalty Payment Amounts,
(ii) the Interest Rate Swap Agreement, (iii) the Interest Rate Cap Agreement,
(iv) the Supplemental Interest Trust, (v) the Excess Reserve Fund Account and
(vi) the right of the LIBOR Certificates to receive Cap Carryover Amounts and
the obligation of the LIBOR Certificates to pay Class IO Shortfalls) be treated
for federal income tax purposes as comprising five REMICs (each, a "Trust REMIC"
or, in the alternative, "Pooling-Tier REMIC-1," "Pooling-Tier REMIC-2,"
"Lower-Tier REMIC," "Upper-Tier REMIC" and "Class CE REMIC," respectively). The
Class CE Interest, Class IO Interest and each Class of LIBOR Certificates (other
than (i) the right of each Class of LIBOR Certificates to receive Cap Carryover
Amounts and the obligation to pay Class IO Shortfalls and (ii) the right of the
Class CE Certificates to receive Net Swap Payments from the Swap Provider and
Cap Payments from the Cap Provider, the obligation to pay Cap Carryover Amounts
to Holders of the LIBOR Certificates and to pay Net Swap Payments and Swap
Termination Payments to the Swap Provider, and the right to receive Class IO
Shortfalls) represent ownership of one or more regular interests in a REMIC for
purposes of the REMIC Provisions.

            The Class R Certificate represents ownership of the sole class of
residual interest in each of Pooling-Tier REMIC-1, Pooling-Tier REMIC-2, the
Lower-Tier REMIC, the Upper-Tier REMIC and the Class CE REMIC for purposes of
the REMIC Provisions.

            The Start-up Day for each Trust REMIC is the Closing Date. The
latest possible maturity date for each regular interest is the latest date
referenced in Section 9.01.

            The Class CE REMIC shall hold as assets the Class UT-X Interest and
the Class UT-IO Interest as set out below. The Upper-Tier REMIC shall hold as
assets the several classes of uncertificated Lower-Tier Regular Interests, set
out below. The Lower-Tier REMIC shall hold as assets the several classes of
uncertificated Pooling-Tier REMIC-2 Regular Interests. Pooling-Tier REMIC-2
shall hold as assets the several classes of uncertificated Pooling-Tier REMIC-1
Regular Interests. Pooling-Tier REMIC-1 shall hold as assets the assets of the
Trust Fund (exclusive of (i) the Prepayment Penalties, the Servicer Prepayment
Penalty Payment Amounts and the Originator Prepayment Penalty Payment Amounts,
(ii) the Interest Rate Swap Agreement, (iii) the Interest Rate Cap Agreement,
(iv) the Supplemental Interest Trust, (v) the Excess Reserve Fund Account, and
(vi) the right of the LIBOR Certificates to receive Cap Carryover Amounts and
the obligation of the LIBOR Certificates to pay Class IO Shortfalls).

            For federal income tax purposes, each Class of LIBOR Certificates,
the Class CE Certificates and the Class P Certificates represent beneficial
ownership of portions of the Trust Fund which shall be treated as a grantor
trust in accordance with Section 9.05.

                              Pooling-Tier REMIC-1

            Pooling-Tier REMIC-1 shall issue the following interests in
Pooling-Tier REMIC-1, and each such interest is hereby designated as a regular
interest in the Pooling-Tier REMIC-1. The Class PT1-R Interest is hereby
designated as the sole class of residual interest in Pooling-Tier REMIC-1. The
Class PT1-R Interest shall have no principal balance and no interest rate.

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-1 Regular Interest shall bear interest at a per annum
       rate (such rate, the "Pooling-Tier REMIC-1 Interest Rate" for such Class)
      equal to the Pooling-Tier REMIC-1 WAC Rate.

(2)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-1 Regular Interest shall bear interest at a per annum
      rate (such rate, the "Pooling-Tier REMIC-1 Interest Rate" for such Class)
      equal to the product of (i) 2 and (ii) the Pooling-Tier REMIC-1 WAC Rate,
      subject to a maximum rate equal to the PT1 Cap.

(3)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-1 Regular Interest shall bear interest at a per annum
      rate (such rate, the "Pooling-Tier REMIC-1 Interest Rate" for such Class)
      equal to the excess, if any, of (A) the product of (i) 2 and (ii) the
      Pooling-Tier REMIC-1 WAC Rate over (B) the PT1 Cap.

            On each Distribution Date, the Securities Administrator shall first
pay from the Trust Fund and charge as an expense of Pooling-Tier REMIC-1 all
expenses of the Trust for such Distribution Date. Such expenses, other than any
Servicing Fee and Insurer Fee, shall be allocated in the same manner as Realized
Losses.

            On each Distribution Date, the interest distributable in respect of
the Mortgage Loans for such Distribution Date shall be deemed to be distributed
to the Pooling-Tier REMIC-1 Regular Interests at the rates shown above.

            On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Mortgage Loans shall be allocated to
the outstanding Pooling-Tier REMIC-1 Regular Interest with the lowest numerical
denomination until the Pooling-Tier REMIC-1 Principal Amount of such interest or
interests, as the case may be, is reduced to zero, provided that, with respect
to Pooling-Tier REMIC-1 Regular Interests with the same numerical denomination,
such Realized Losses, Subsequent Recoveries and payments of principal shall be
allocated pro rata between such Pooling-Tier REMIC-1 Regular Interests.

                              Pooling-Tier REMIC-2

            Pooling-Tier REMIC-2 shall issue the following interests in
Pooling-Tier REMIC-2, and each such interest, other than the Class PT2-R
Interest, is hereby designated as a regular interest in Pooling-Tier REMIC-2.
The Class PT2-R Interest is hereby designated as the sole class of residual
interest in Pooling-Tier REMIC-2 and shall be represented by the Class R
Certificate. The Class PT2-R Interest shall have no principal balance and no
interest rate.

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (such rate, the "Pooling-Tier REMIC-2 Interest Rate" for such Class)
      equal to the Pooling-Tier REMIC-1 WAC Rate.

(2)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (such rate, the "Pooling-Tier REMIC-2 Interest Rate" for such Class)
      equal to the weighted average of the Pooling-Tier REMIC-1 Interest Rates
      on the Pooling-Tier REMIC-1 Regular Interests having an "A" in their class
      designation, provided that, on each Distribution Date on which interest is
      distributable on the Corresponding Pooling-Tier REMIC-2 IO Interest, this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate equal to Swap LIBOR subject to a maximum rate equal to the weighted
      average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
      REMIC-1 Regular Interests having an "A" in their class designation.

(3)    For any Distribution Date (and the related Interest Accrual Period) this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (such rate, the "Pooling-Tier REMIC-2 Interest Rate" for such Class)
      equal to the weighted average of the Pooling-Tier REMIC-1 Interest Rates
      on the Pooling-Tier REMIC-1 Regular Interests having a "B" in their class
      designation.

(4)    Each Pooling-Tier REMIC-2 IO Interest is an interest-only interest and
      does not have a principal balance. From the Closing Date through and
      including the Corresponding Scheduled Crossover Distribution Date, each
      Pooling-Tier REMIC-2 IO Interest shall be entitled to receive interest
       that accrues on the Corresponding Pooling-Tier REMIC-1 Regular Interest at
      a rate equal to the excess, if any, of (i) the Pooling-Tier REMIC-1
      Interest Rate for the Corresponding Pooling-Tier REMIC-1 Regular Interest
      over (ii) Swap LIBOR. After the Corresponding Scheduled Crossover
      Distribution Date, the Pooling-Tier REMIC-2 IO Interest shall not accrue
      interest.

            On each Distribution Date, the interest distributable in respect of
the Mortgage Loans for such Distribution Date shall be distributed to the
Pooling-Tier REMIC-2 Regular Interests at the Pooling-Tier REMIC-2 Interest
Rates shown above.

            On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Mortgage Loans shall be allocated to
the outstanding Pooling-Tier REMIC-2 Regular Interests (other than the
Pooling-Tier REMIC-2 IO Interests) with the lowest numerical denomination until
the Pooling-Tier REMIC-2 Principal Amount of such interest or interests, as the
case may be, is reduced to zero, provided however that, for Pooling-Tier REMIC-2
Regular Interests with the same numerical denomination, such Realized Losses,
Subsequent Recoveries and payments of principal shall be allocated pro rata
between such Pooling-Tier REMIC-2 Regular Interests.

                                Lower-Tier REMIC

            The Lower-Tier REMIC shall issue the following interests, and each
such interest, other than the Class LT-R Interest, is hereby designated as a
regular interest in the Lower-Tier REMIC. The Class LT-R Interest is hereby
designated as the sole class of residual interest in the Lower-Tier REMIC and
shall be represented by the Class R Certificate. The Class LT-R Interest shall
have no principal balance and no interest rate.

----------

(1)    The interest rate with respect to any Distribution Date for these
      interests is a per annum variable rate equal to the weighted average of
      the Pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
      Regular Interests (other than the Pooling-Tier REMIC-2 IO Interests).

(2)    This Lower-Tier Regular Interest is an interest-only interest and does not
      have a Lower-Tier Principal Amount. On each Distribution Date, this
      Lower-Tier Regular Interest shall be entitled to receive all interest
      distributable on the Pooling-Tier REMIC-2 IO Interests.

             Each Lower-Tier Regular Interest is hereby designated as a regular
interest in the Lower-Tier REMIC. The Class LT-A-1, Class LT-A-2, Class LT-A-3,
Class LT-M-1, Class LT-M-2, Class LT-M-3, Class LT-M-4, Class LT-M-5, Class
LT-M-6, Class LT-B-1, Class LT-B-2, Class LT-B-3 and Class LT-B-4 Interests are
hereby designated the LT-Accretion Directed Classes (the "LT-Accretion Directed
Classes").

            On each Distribution Date, 50% of the increase in the
Overcollateralization Amount shall be payable as a reduction of the Lower-Tier
Principal Amount of the LT-Accretion Directed Classes (each such Class will be
reduced by an amount equal to 50% of any increase in the Overcollateralization
Amount that is attributable to a reduction in the Principal Balance of its
Corresponding Class) and shall be accrued and added to the Lower-Tier Principal
Amount of the Class LT-Accrual Interest. On each Distribution Date, the increase
in the Lower-Tier Principal Amount of the Class LT-Accrual Interest shall not
exceed interest accruals for such Distribution Date for the Class LT-Accrual
Interest. In the event that: (i) 50% of the increase in the
Overcollateralization Amount exceeds (ii) interest accruals on the Class
LT-Accrual Interest for such Distribution Date, the excess for such Distribution
Date (accumulated with all such excesses for all prior Distribution Dates) will
be added to any increase in the Overcollateralization Amount for purposes of
determining the amount of interest accrual on the Class LT-Accrual Interest
payable as principal on the LT-Accretion Directed Classes on the next
Distribution Date pursuant to the first sentence of this paragraph. All payments
of scheduled principal and prepayments of principal generated by the Mortgage
Loans and all Subsequent Recoveries allocable to principal shall be allocated
(i) 50% to the Class LT-Accrual Interest and (ii) 50% to the LT-Accretion
Directed Classes (such principal payments and Subsequent Recoveries shall be
allocated among such LT-Accretion Directed Classes in an amount equal to 50% of
the principal amounts and Subsequent Recoveries allocated to their respective
Corresponding Classes), until paid in full. Notwithstanding the above, principal
payments allocated to the Class UT-X Interest that result in the reduction in
the Overcollateralization Amount shall be allocated to the Class LT-Accrual
Interest (until paid in full). Realized Losses shall be applied so that after
all distributions have been made on each Distribution Date (i) the Lower-Tier
Principal Amount of each of the LT-Accretion Directed Classes is equal to 50% of
the Principal Balance of their Corresponding Class, and (ii) the Class
LT-Accrual Interest is equal to 50% of the Pool Balance plus 50% of the
Overcollateralization Amount. Any increase in the Principal Balance of a Class
of LIBOR Certificates as a result of a Subsequent Recovery shall increase the
Lower-Tier Principal Amount of the Corresponding Lower-Tier Regular Interest by
50% of such increase, and the remaining 50% of such increase shall increase the
Lower-Tier Principal Amount of the Class LT-Accrual Interest.

                                Upper-Tier REMIC

            The Upper-Tier REMIC shall issue the following interests, and each
such interest, other than the Class UT-R Interest, is hereby designated as a
regular interest in the Upper-Tier REMIC. The Class UT-R Interest is hereby
designated as the sole class of residual interests in the Upper-Tier REMIC and
shall be represented by the Class R Certificate. The Class UT-R Interest shall
have no principal balance and no interest rate.

----------

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the lesser of (i) the Pass-Through Rate
      (determined without regard to the Pool Cap) for the Corresponding Class of
       Certificates, and (ii) the Upper-Tier REMIC WAC Rate.

(2)    This interest is an interest-only interest and does not have a principal
      balance. On each Distribution Date, the Class UT-IO Interest shall be
      entitled to receive all interest distributable on the Class LT-IO
      Interest.

(3)    The Class UT-X Interest has an initial principal balance of $29,585,677.00
      but will not accrue interest on such balance but will accrue interest on a
      notional amount. As of any Distribution Date, the Class UT-X Interest
      shall have a notional amount equal to the aggregate of the Lower-Tier
      Principal Amounts of the Lower-Tier Regular Interests (other than the
      Class LT-IO Interest) as of the first day of the related Interest Accrual
      Period. With respect to any Interest Accrual Period, the Class UT-X
      Interest shall bear interest at a rate equal to the excess, if any, of the
      Upper-Tier REMIC WAC Rate over the product of (i) 2 and (ii) the weighted
      average of the Lower-Tier Interest Rates of the Lower-Tier REMIC Interests
      (other than the Class LT-IO Interest), where the Lower-Tier Interest Rate
      on the Class LT-Accrual Interest is subject to a cap equal to zero and
      each LT-Accretion Directed Class is subject to a cap equal to the
      Upper-Tier Interest Rate on its Corresponding Class of Upper-Tier Regular
      Interest. With respect to any Distribution Date, interest that so accrues
      on the notional amount of the Class UT-X Interest shall be deferred in an
      amount equal to any increase in the Overcollateralization Amount on such
      Distribution Date. Such deferred interest shall not itself bear interest.

            On each Distribution Date, interest distributable in respect of the
Lower-Tier Interests for such Distribution Date shall be deemed to be
distributed on the interests in the Upper-Tier REMIC at the rates shown above,
provided that the Class UT-IO Interest shall be entitled to receive interest
before any other interest in the Upper-Tier REMIC.

            On each Distribution Date, all Realized Losses, Subsequent
Recoveries and all payments of principal shall be allocated to the Upper-Tier
Interests until the outstanding principal balance of each such interest equals
the outstanding Principal Balance of the Corresponding Class of Certificates as
of such Distribution Date.

                                 Class CE REMIC

            The Class CE REMIC shall issue the following classes of interests.
The Class CE Interest and the Class IO Interest shall each represent a regular
interest in the Class CE REMIC and the Class R Certificate shall represent the
sole class of residual interest in the Class CE REMIC.

Class R-CE Interest       (3)             (3)


----------

(1)    The Class CE Interest has an initial principal balance equal to the
      initial principal balance of the Class UT-X Interest and is entitled to
      100% of the interest and principal on the Class UT-X Interest on each
      Distribution Date.

(2)    This interest is an interest-only interest and does not have a principal
      balance. On each Distribution Date the Class IO Interest shall be entitled
      to receive 100% of the interest distributable on the Class UT-IO Interest.

(3)    The Class R-CE Interest does not have a principal balance or an interest
      rate.

Document Transfer Date, copies (which may be in electronic form mutually agreed
upon by the Depositor and the Custodian) of the following additional documents
or instruments with respect to each Mortgage Loan; provided, however, that

is located in order to exercise all remedies available to the Trust under
applicable law following default by the related Mortgagor:

      of such assignment with such evidence of recordation to be true and

            (c) If any assignment of a Mortgage to the Trustee is in the process
of being recorded on the Closing Date, the Depositor shall use its best efforts
to cause each such original recorded document or certified copy thereof to be
delivered to the Custodian promptly following its recordation, but in no event
later than one (1) year following the Closing Date. If any Mortgage has been
recorded in the name of MERS or its designee, no assignment of Mortgage in favor
of the Trustee will be required to be prepared or delivered and instead, the
Servicer shall take all actions as are necessary to cause the Trust Fund to be
shown as the owner of the related Mortgage Loan on the records of MERS for the
purpose of the system of recording transfers of beneficial ownership of
mortgages maintained by MERS. The Depositor shall also cause to be delivered to
the Custodian any other original mortgage loan document included in the Owner
Mortgage File (and, if applicable, the Retained Mortgage File) if a copy thereof
has been delivered. The Depositor shall pay from its own funds, without any
right of reimbursement therefor, the amount of any costs, liabilities and
expenses incurred by the Trust by reason of the failure of the Depositor to
cause to be delivered to the Custodian within one (1) year following the Closing
Date any assignment of a Mortgage (except with respect to any Mortgage recorded
in the name of MERS) not delivered to the Custodian on the Closing Date.

            In lieu of recording an assignment of any Mortgage the Depositor
may, deliver or cause to be delivered to the Custodian the assignment of the
Mortgage Loan to the Trustee in a form suitable for recordation, if (i) with
respect to a particular state the Trustee and the Custodian have received an
Opinion of Counsel acceptable to it that such recording is not required to make
the assignment effective against the parties to the Mortgage or subsequent
purchasers or encumbrancers of the Mortgaged Property or (ii) the Depositor has
been advised by each Rating Agency that non recordation in a state will not
result in a reduction of the rating assigned by that Rating Agency at the time
of initial issuance of the Certificates. Set forth on Exhibit Q attached hereto
is a list of all states where recordation is required by any Rating Agency to
obtain the initial ratings of the Certificates. The Custodian may rely and shall
be protected in relying upon the information contained in such Exhibit Q. In the
event that the Custodian receives notice that recording is required to protect
the right, title and interest of the Trustee in and to any such Mortgage Loan
for which recordation of an assignment has not previously been required, the
Custodian shall promptly notify the Trustee and the Custodian shall within five
Business Days (or such other reasonable period of time mutually agreed upon by
the Custodian and the Trustee) of its receipt of such notice deliver each
previously unrecorded assignment to the related Servicer for recordation.

            (d) Except for Mortgage Notes endorsed in blank, endorsements shall

days after completion of such review to the Servicer, the Securities
Administrator, the Trustee and the Depositor a final certification in the form
of Exhibit F-2 hereto to the effect that, except as may be specified in a list
of exceptions attached thereto, all required documents set forth in Section
2.01(a) have been executed and received and appear regular on their face, and
that such documents relate to the Mortgage Loans identified in the Mortgage Loan
Schedule based on a comparison of the Mortgage Loan identifying number,
Mortgagor name and street address, and in so doing the Custodian may rely on the
purported due execution and genuineness of any such document and on the
purported genuineness of any signature thereon.

            If in the process of reviewing the Mortgage Files and making or
preparing, as the case may be, the certifications referred to above, the
Custodian finds any document or documents constituting a part of a Mortgage File
to be missing or defective in any material respect, at the conclusion of its
review the Custodian shall so notify the Depositor, the Trustee, the Securities
Administrator and the Servicer.

            The Securities Administrator is hereby directed to execute and
deliver, on behalf of the Supplemental Interest Trust, the Interest Rate Swap
Agreement and the Interest Rate Cap Agreement.

             If the Interest Rate Swap Agreement or Interest Rate Cap Agreement
is terminated, the Securities Administrator shall enter into a replacement
interest rate swap agreement or interest rate cap agreement, as applicable, upon
written direction of the Depositor.

            Section 2.03 Repurchase or Substitution of Mortgage Loans by the
Depositor. (a) Upon discovery or receipt of written notice of any materially
defective document in, or that a document is missing from, an Owner Mortgage
File (or, if applicable, a Retained Mortgage File) or of a breach of a
representation of warranty of the Depositor in Section 2.04 hereof, in respect
of any Mortgage Loan and such breach materially adversely affects the value of
such Mortgage Loan, Prepayment Penalty or the interest therein of the
Certificateholders, the Trustee (or the Custodian) shall promptly (and in no
event more than 30 days after completion of the review) notify the Depositor and
the Servicer of such defect, missing document or breach and request that the
Depositor cure such defect or breach or deliver such missing document within 60
days from the date the Depositor was notified of such missing document, breach
or defect. If the Depositor does not deliver such missing document or cure such
defect or cure such breach in all material respects during such period, the
Depositor shall repurchase such Mortgage Loan from the Trust Fund at the
Purchase Price on or prior to the Determination Date following the expiration of
such period (subject to Section 2.03(d) and the last paragraph of this Section
2.03(a)). The Purchase Price for the repurchased Mortgage Loan shall be
deposited in the Collection Account, and the Custodian, upon receipt of written
notice from the Servicer of such deposit, shall release to the Depositor the
Owner Mortgage File (and, if applicable, Retained Mortgage File) of the Mortgage
Loan being repurchased. The Trustee shall execute and deliver such instruments
of transfer or assignment (or, in the case of a Mortgage Loan registered in the
name of MERS or its designee, the Servicer shall reflect such assignment on the
records of MERS), in each case without recourse, as the Depositor shall furnish
to it and as shall be necessary to vest in the Depositor any Mortgage Loan
released pursuant hereto and the Custodian and the Trustee shall have no further
responsibility with regard to such Owner Mortgage File (and, if applicable,
Retained Mortgage File). In lieu of repurchasing any such Mortgage Loan as
provided above, the Depositor may cause such Mortgage Loan to be removed from
the Trust Fund (in which case it shall become a Defective Mortgage Loan) and
substitute one or more Eligible Substitute Mortgage Loans in the manner and
subject to the limitations set forth in Section 2.03(d).

            It is understood and agreed that the representations and warranties
set forth in Section 2.04 hereof shall survive delivery of the Owner Mortgage
Files (and, if applicable, Retained Mortgage Files) to the Custodian and shall
inure to the benefit of the Certificateholders notwithstanding any restrictive
or qualified endorsement or assignment. It is understood and agreed that the
obligations of the Depositor set forth in this Section 2.03(a) to cure,
substitute for or repurchase a Mortgage Loan and to pay the Reimbursement Amount
constitute the sole remedies available to the Certificateholders and to the
Trustee on their behalf respecting a breach of the representations and
warranties in Section 2.04 hereof.

            (b) In addition to the foregoing, in the case of a breach of the
Depositor's representation set forth in Section 2.04(i) and (dd) hereof, the
Depositor shall pay to the Trust the Reimbursement Amount. The Reimbursement
Amount shall be delivered to the Servicer for deposit into the Collection
Account within 10 days from the date the Depositor was notified by the Trustee
of the amount of such costs and damages.

            (c) Within 90 days of the earlier of discovery by the Servicer or
receipt of notice by the Servicer of the breach of any representation, warranty
or covenant of the Servicer set forth in Section 2.05 which materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the Servicer shall cure such breach in all material respects.

            (d) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Defective Mortgage Loan for which the Depositor substitutes an Eligible
Substitute Mortgage Loan or Loans, such substitution shall be effected by the
Depositor delivering to the Custodian, on the Trustee's behalf for such Eligible
Substitute Mortgage Loan or Loans, the documents required by Section 2.01,
together with an Officer's Certificate providing that each such Eligible
Substitute Mortgage Loan satisfies the definition thereof and specifying the
Substitution Adjustment Amount, if any, in connection with such substitution.
The Custodian shall acknowledge receipt for such Eligible Substitute Mortgage
Loan or Loans and, within ten Business Days thereafter, the Custodian shall
review such documents as specified in Section 2.02 and deliver to the Servicer
and the Trustee, with respect to such Eligible Substitute Mortgage Loan or
Loans, a certification substantially in the form attached hereto as Exhibit F-1,
with any applicable exceptions noted thereon. Within one year of the date of
substitution, the Custodian shall deliver to the Servicer and the Trustee a
certification substantially in the form of Exhibit F-2 hereto with respect to
such Eligible Substitute Mortgage Loan or Loans, with any applicable exceptions
noted thereon. Monthly Payments due with respect to Eligible Substitute Mortgage
Loans in the month of substitution are not part of the Trust Fund and will be
retained by the Depositor. For the month of substitution, distributions to
Certificateholders will reflect the collections and recoveries in respect of
such Defective Mortgage Loan in the Collection Period or Prepayment Period, as
applicable, preceding the date of substitution and the Depositor shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Defective Mortgage Loan. The Depositor shall give or cause to be given
written notice to the Certificateholders that such substitution has taken place,
shall amend the Mortgage Loan Schedule to reflect the removal of such Defective
Mortgage Loan from the terms of this Agreement and the substitution of the
Eligible Substitute Mortgage Loan or Loans and shall deliver a copy of such
amended Mortgage Loan Schedule to the Trustee, the Servicer, the Securities
Administrator and the Custodian. Upon such substitution, such Eligible
Substitute Mortgage Loan or Loans shall constitute part of the Mortgage Pool and
shall be subject in all respects to the terms of this Agreement, including all
applicable representations and warranties as of the date of substitution.

            For any month in which the Depositor substitutes one or more
Eligible Substitute Mortgage Loans for one or more Defective Mortgage Loans, the
Servicer will determine the amount (the "Substitution Adjustment Amount"), if
any, by which the aggregate Purchase Price of all such Defective Mortgage Loans
exceeds the aggregate, as to each such Eligible Substitute Mortgage Loan, of the
principal balance thereof as of the date of substitution, together with one
month's interest on such principal balance at the applicable Net Mortgage
Interest Rate. On the date of such substitution, the Depositor will deliver or
cause to be delivered to the Servicer for deposit in the Collection Account an
amount equal to the Substitution Adjustment Amount, if any, and the Custodian,
on behalf of the Trustee, upon receipt of the related Eligible Substitute
Mortgage Loan or Loans and notice by the Servicer of such deposit, shall release
to the Depositor the related Owner Mortgage File (and, if applicable, Retained
Mortgage File) and the Trustee shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as the Depositor shall
deliver to it and as shall be necessary to vest therein any Defective Mortgage
Loan released pursuant hereto.

            The Depositor shall determine the Purchase Price or the eligibility
of any Eligible Substitute Mortgage Loan and the Trustee shall be protected in
relying on such determination.

            (e) Upon discovery by the Depositor, the Seller, the Servicer, the
Securities Administrator, the Custodian 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 within two
Business Days give written notice thereof to the other parties. In connection
therewith, the Depositor shall repurchase or, subject to the limitations set
forth in Section 2.03(d), substitute one or more Eligible Substitute Mortgage
Loans for the affected Mortgage Loan within 60 days of the earlier of discovery
or receipt of such notice with respect to such affected Mortgage Loan. In
addition, upon discovery that a Mortgage Loan is defective in a manner that
would cause it to be a "defective obligation" within the meaning of Treasury
Regulations relating to REMICs, the Depositor shall cure the defect or make the
required purchase or substitution no later than 60 days after the discovery of
the defect. Any such repurchase or substitution shall be made in the same manner
as set forth in Section 2.03(a). The Trustee shall reconvey to the Depositor 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.

            (f) The Trustee shall be responsible for enforcing the Depositor's
obligations under this Section 2.03. If the Trustee receives written notice from
the Custodian or the Securities Administrator that the defect is not cured by
the Depositor within 60 days after the Trustee's notice, the Trustee shall
enforce the Depositor's obligation to repurchase such Mortgage Loan or
substitute for such Mortgage Loan in accordance with the provisions of this
Section 2.03. In connection with any substitution permitted by this Section
2.03, the Trustee shall verify that the unpaid principal balance and the
Loan-to-Value Ratio of the Eligible Substitute Mortgage Loan satisfy the
requirements of this Section 2.03.

            Section 2.04 Representations and Warranties of the Depositor with
respect to the Mortgage Loans. The Depositor hereby represents and warrants to
the Trustee for the benefit of the Certificateholders that as of the Closing
Date or as of such other date specifically provided herein:

            (a) The information set forth in the Mortgage Loan Schedule was true
and correct in all material respects, including, without limitation, the
information regarding any Prepayment Penalty, at the date or dates respecting
which such information was furnished as specified in the Mortgage Loan Schedule;

            (b) Immediately prior to the transfer and assignment contemplated
herein, the Depositor was the sole owner and holder of the Mortgage Loan free
and clear of any and all liens, pledges, charges or security interests of any
nature and has full right and authority to sell and assign the same;

            (c) All payments required to be made up to the Due Date for such
Mortgage Loan immediately preceding the Closing Date under the terms of the
related Mortgage Note have been made and no Mortgage Loan had more than one
delinquency in the 12 months preceding the applicable Cut-off Date;

            (d) The Mortgage Note, the related Mortgage and other agreements
executed in connection therewith are genuine, and each is the legal, valid and
binding obligation of the maker thereof, enforceable in accordance with its
terms, except as such enforcement may be limited by bankruptcy, insolvency,
reorganization or other similar laws affecting the enforcement of creditors'
rights generally and by general equity principles (regardless of whether such
enforcement is considered in a proceeding in equity or at law); and, to the best
of the Depositor's knowledge, all parties to the Mortgage Note and the Mortgage
had legal capacity to execute the Mortgage Note and the Mortgage and each
Mortgage Note and Mortgage has been duly and properly executed by the Mortgagor;

            (e) All taxes, governmental assessments, insurance premiums, and
water, sewer and municipal charges, which previously became due and owing have
been paid, or an escrow of funds has been established, to the extent permitted
by law, in an amount sufficient to pay for every such item which remains unpaid;
and neither the Servicer nor the Depositor has advanced funds, or 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, except for interest accruing
from the date of the Mortgage Note or date of disbursement of the Mortgage Loan
proceeds, whichever is later, to the day which precedes by thirty days the first
Due Date under the related Mortgage Note;
