            This Pooling and Servicing Agreement is dated as of [ ], 200 (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 twenty-two
Classes of Certificates, designated as (i) the Class AI-1A, Class AI-1B, Class
AII-1, Class AII-2 and Class AII-3 Certificates, (ii) the Class M-1, Class M-2,
Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9,
Class M-10, Class M-11, Class M-12 and Class M-13 Certificates, (iii) the Class
CE Certificates, (iv) the Class P Certificates and (v) the Class R and Class R-X
Certificates.

                                     REMIC 1

            As provided herein, the Trustee will make an election to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (but exclusive of the Yield Maintenance
Agreement, the Reserve Account, the Cap Carryover Amounts, the Prepayment
Penalties, the Servicer Prepayment Penalty Payment Amounts and the Originator
Prepayment Penalty Payment Amounts) as a real estate investment conduit (a
"REMIC") for federal income tax purposes, and such segregated pool of assets
will be designated as "REMIC 1." The Class R-1 Interest will represent the sole
class of "residual interests" in REMIC 1 for purposes of the REMIC Provisions
under federal income tax law. The following table irrevocably sets forth the
designation, the Uncertificated REMIC 1 Pass-Through Rate, the initial
Uncertificated Principal Balance, and solely for purposes of satisfying Treasury

each of the REMIC 1 Regular Interests. None of the REMIC 1 Regular Interests
will be certificated.

            (b) The Securities Administrator shall promptly notify the
Depositor, the Trustee and the Custodian of the occurrence of any Document
Transfer Event of which the Servicer had knowledge. Following the receipt of
such notice, the Depositor shall, with respect to each Mortgage Loan, deliver,
or cause to be delivered, to the Custodian, no later than the 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
originals of such documents or instruments shall be delivered to the Custodian
if originals are required under the law in which the related Mortgaged Property
is located in order to exercise all remedies available to the Trust under
applicable law following default by the related Mortgagor:

            (i) The original recorded Mortgage with evidence of recordation
      noted thereon or attached thereto, together with any addenda or riders
      thereto, or a copy of such recorded Mortgage with such evidence of
      recordation certified to be true and correct by the appropriate
      governmental recording office; or a copy of such recorded Mortgage with
      such evidence of recordation, or if the original Mortgage has been
      submitted for recordation but has not been returned from the applicable

      evidence of recording thereon or copies thereof certified by an officer of
      Wells Fargo Bank or the applicable Wells Fargo Bank Correspondent to have
      been submitted for recordation;

            (iv) Each original recorded intervening assignment of the Mortgage
      as may be necessary to show a complete chain of title from the Mortgage
      Loan originator to Wells Fargo Bank or Wells Fargo Home Mortgage, Inc.,
      with evidence of recordation noted thereon or attached thereto, or a copy
      of such assignment with such evidence of recordation to be true and
      correct by the appropriate governmental recording office, or, if any such
      assignment has been submitted for recordation but has not been returned
      from the applicable public recording office or is not otherwise available,

      Fargo Bank or the applicable Wells Fargo Bank Correspondent that such
      attorney's certificate of title is customarily used in lieu of a title
      insurance policy in the jurisdiction in which the related mortgage
      property is located.

            (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
Master 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 either 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
comply with the following format:

                                WITHOUT RECOURSE
                               PAY TO THE ORDER OF:

            [Wells Fargo Bank, N.A.][Wells Fargo Home Mortgage, Inc.]
                             [Signature of Officer]
                           [Officer's Name and Title]

            Except where assignments in blank are authorized or in the case of
any Mortgage registered in the name of MERS, assignments of any Mortgage shall
comply with the following:

                     HSBC BANK USA, NATIONAL ASSOCIATION, AS
                                     TRUSTEE
                          and its successors and assigns

            (e) Concurrently with the execution and delivery of this Agreement,
the Depositor shall deliver the Mortgage Loan Schedule to the Trustee, the
Securities Administrator, the Servicer and the Custodian. The Depositor and the
Securities Administrator shall provide a copy of the Mortgage Loan Schedule to
any Certificateholders upon written request made to it at the addresses set
forth on Exhibit D, as the same may be amended from time to time by written
notice from such party to the other parties hereto.

            (f) The Securities Administrator shall monitor the rating of Wells
Fargo & Company and upon the occurrence of a Document Transfer Event relating to
such rating, shall promptly notify the Servicer, Depositor, Trustee and
Custodian of the occurrence of such Document Transfer Event.

            Section 2.02 Acceptance by Custodian. The Custodian, on behalf of
the Trustee, acknowledges the receipt of, subject to the provisions of Section
2.01 and subject to the review described below and any exceptions noted on the
exception report described in the next paragraph below, the documents referred
to in Section 2.01 above and all other assets included in the definition of
"Trust Fund" and declares that it holds and will hold such documents and the
other documents delivered to it constituting the Owner Mortgage File (and in the
case of a Document Transfer Event, the Retained Mortgage File), and that it
holds or will hold all such assets and such other assets included in the
definition of "Trust Fund" in trust for the exclusive use and benefit of all
present and future Certificateholders.

            The Custodian, for the benefit of the Certificateholders, shall
execute and deliver to the Servicer, the Securities Administrator, the Trustee
and the Depositor on or prior to the Closing Date an initial certification in
the form attached hereto as Exhibit F-1 hereto, to the effect that, except as
may be specified in a list of exceptions attached thereto, it has received the
original Mortgage Notes (described in Section 2.01(a)(i)) relating to each
Mortgage Loan listed in the Mortgage Loan Schedules (other than any Mortgage
Loan that has been paid in full, liquidated or otherwise released as of the date
of such certification, and subject to any exceptions specifically identified in
the exception report annexed to such certification).

            The Custodian will review each Owner Mortgage File within 45 days
after execution of this Agreement. The Custodian will deliver no later than 30
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 Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans and the
Related Documents, conveying good title thereto free and clear of any liens and
encumbrances, from the Depositor to the Trustee and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee, on behalf
of the Trust, a first priority perfected security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and the
Related Documents, and that this Agreement shall constitute a security agreement
under applicable law.

            The Securities Administrator is hereby directed to execute and
deliver, on behalf of the Trust, the Yield Maintenance Agreement.

            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, except for a breach of the representations and
warranties set forth in clause (ee) of Section 2.04, 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 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 related Owner Mortgage File (and, if applicable, Retained
Mortgage File). 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) 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 Officers' Certificate providing that each such Eligible
Substitute Mortgage Loan satisfies the definition thereof and specifying the
Substitution Adjustment Amount (as described below), 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 applicable 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 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
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.

            In addition, the Depositor shall obtain at its own expense and
deliver to the Trustee an Opinion of Counsel to the effect that such
substitution will not cause (a) any federal tax to be imposed on the Trust Fund,
including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(l) of the Code or on "contributions after
the startup date" under Section 860G(d)(l) of the Code, or (b) any REMIC created
hereunder to fail to qualify as a REMIC at any time that any Certificate is
outstanding. If such Opinion of Counsel can not be delivered, then such
substitution may only be effected at such time as the required Opinion of
Counsel can be given.

            (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

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

             (g) No Mortgage Note or Mortgage is subject to any right of
rescission, set-off, counterclaim or defense, including the defense of usury,
nor will the operation of any of the terms of the Mortgage Note or Mortgage, or
the exercise of any right thereunder, render the Mortgage Note or Mortgage
unenforceable, in whole or in part, or subject it to any right of rescission,
set-off, counterclaim or defense, including the defense of usury, and no such
right of rescission, set-off, counterclaim or defense has been asserted with
respect thereto;

            (h) The Mortgage is a valid, subsisting and enforceable first lien
on the property therein described, and the Mortgaged Property is free and clear
of all encumbrances and liens having priority over the first lien of the
Mortgage except for liens for real estate taxes and special assessments not yet
due and payable and liens or interests arising under or as a result of any

detached home, townhouse, condominium unit, a unit in a planned unit development
or a manufacturing housing unit which constitutes real property for purposes of
the applicable state law;

            (k) Except for Mortgage Loans secured by residential long-term

all of the improvements which are 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 (unless insured against under
the related title insurance policy); and to the best of the Depositor's
knowledge, the Mortgaged Property and all improvements thereon comply with all
requirements of any applicable zoning and subdivision laws and ordinances;

            (l) With respect to each Mortgage where a lost note affidavit has
been delivered to the Custodian on the Trustee's behalf in place of the related

expenses incurred in making, closing or recording the Mortgage Loan have been
paid, except recording fees with respect to Mortgages not recorded as of the
Closing Date;

            (n) The Mortgage Loan (except any Mortgage Loan secured by a
Mortgaged Property located in any jurisdiction, as to which an opinion of
counsel of the type customarily rendered in such jurisdiction in lieu of title
insurance is instead received) is covered by an American Land Title Association
mortgagee title insurance policy or other generally acceptable form of policy or
insurance acceptable to Fannie Mae or Freddie Mac, issued by a title insurer
acceptable to Fannie Mae or Freddie Mac insuring the originator, its successors
and assigns, as to the first priority lien of the Mortgage in the original
principal amount of the Mortgage Loan and subject only to (A) the lien of
current real property taxes and assessments not yet due and payable, (B)
covenants, conditions and restrictions, rights of way, easements and other
matters of public record as of the date of recording of such Mortgage acceptable

with the origination of the related Mortgage Loan, (C) liens created pursuant to
any federal, state or local law, regulation or ordinance affording liens for the
costs of clean-up of hazardous substances or hazardous wastes or for other
environmental protection purposes and (D) such other matters to which like
properties are commonly subject which do not individually, or in the aggregate,
materially interfere with the benefits of the security intended to be provided
by the Mortgage; the Depositor is the sole insured of such mortgagee title
insurance policy, the assignment to the Trustee of the Depositor's interest in
such mortgagee title insurance policy does not require any consent of or
notification to the insurer which has not been obtained or made, such mortgagee
title insurance policy is in full force and effect and will be in full force and
effect and inure to the benefit of the Trustee, no claims have been made under
such mortgagee title insurance policy, and no prior holder of the related
Mortgage, including the Depositor, has done, by act or omission, anything which
would impair the coverage of such mortgagee title insurance policy;

            (o) To the best of the Depositor's knowledge, there is no default,
breach, violation or event of acceleration existing under the Mortgage or the
related Mortgage Note and no event which, 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; the Depositor has not
waived any default, breach, violation or event of acceleration; and no
foreclosure action is currently threatened or has been commenced with respect to
the Mortgage Loan;

            (p) The Mortgaged Property is free and clear of all mechanics' and
materialmen's liens or liens in the nature thereof; provided, however, that this
warranty shall be deemed not to have been made at the time of the initial
issuance of the Certificates if a title policy affording, in substance, the same
protection afforded by this warranty is furnished to the Trustee by the
Depositor;

            (q) The Mortgage Loan meets, or is exempt from, applicable state or
federal laws, regulations and other requirements, pertaining to usury, and the
Mortgage Loan is not usurious;

            (r) To the best of the Depositor's knowledge, all inspections,
licenses and certificates required to be made or issued with respect to all
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;

            (s) Each Mortgage Note (other than with respect to any Balloon
Loans) is payable in monthly payments, resulting in complete amortization of the
Mortgage Loan over a term of not more than 360 months;

            (t) Each Mortgage contains customary and enforceable provisions such
as to render the rights and remedies of the holder thereof adequate for the
realization against the Mortgaged Property of the benefits of the security,
including realization by judicial foreclosure (subject to any limitation arising
from any bankruptcy, insolvency or other law for the relief of debtors), and
there is no homestead or other exemption available to the Mortgagor which would
interfere with such right of foreclosure;

            (u) The Mortgaged Property is undamaged by water, fire, earthquake,
earth movement other than earthquake, windstorm, flood, tornado or similar
casualty (excluding casualty from the presence of hazardous wastes or hazardous
substances, as to which the Depositor makes no representations), in a matter
which would adversely affect the value of the Mortgaged Property as security for
the Mortgage Loan or the use for which the premises were intended and to the
best of the Depositor's knowledge, there is no proceeding pending or threatened
for the total or partial condemnation of the Mortgaged Property;

            (v) The Mortgaged Property securing each Mortgage Loan is insured by
an insurer acceptable to Fannie Mae or Freddie Mac against loss by fire and such
hazards as are covered under a standard extended coverage endorsement, in an
amount which is not less than the lesser of 100% of the insurable value of the
Mortgaged Property and the outstanding principal balance of the Mortgage Loan,
but in no event less than the minimum amount necessary to fully compensate for
any damage or loss on a replacement cost basis; if the Mortgaged Property is a
condominium unit, it is included under the coverage afforded by a blanket policy
for the project; if upon origination of the Mortgage Loan, the improvements on
the Mortgaged Property were in an area identified in the Federal Register by the
Federal Emergency Management Agency as having special flood hazards, a flood
insurance policy meeting the requirements of the current guidelines of the
Federal Insurance Administration is in effect with a generally acceptable
insurance carrier, in an amount representing coverage not less than the least of
(A) the outstanding principal balance of the Mortgage Loan, (B) the full
insurable value of the Mortgaged Property and (C) the maximum amount of
insurance which was available under the National Flood Insurance Act of 1968, as
amended; and each Mortgage obligates the Mortgagor thereunder to maintain all
such insurance at the Mortgagor's cost and expense;

            (w) To the best of the Depositor's knowledge, no Mortgagor is a
debtor in any state or federal bankruptcy or insolvency proceeding;

            (x) If the Mortgage Loan is secured by a long-term residential
lease, (1) the lessor under the lease holds a fee simple interest in the land;
(2) the terms of such lease expressly permit the mortgaging of the leasehold
estate, the assignment of the lease without the lessor's consent and the
acquisition by the holder of the Mortgage of the rights of the lessee upon
foreclosure or assignment in lieu of foreclosure or provide the holder of the
Mortgage with substantially similar protections; (3) the terms of such lease do
not (a) allow the termination thereof upon the lessee's default without the
holder of the Mortgage being entitled to receive written notice of, and
opportunity to cure, such default, (b) allow the termination of the lease in the
event of damage or destruction as long as the Mortgage is in existence, (c)
prohibit the holder of the Mortgage from being insured (or receiving proceeds of
insurance) under the hazard insurance policy or policies relating to the
Mortgaged Property or (d) permit any increase in rent other than pre-established
increases set forth in the lease; (4) the original term of such lease is not
less than 15 years; (5) the term of such lease does not terminate earlier than
five years after the maturity date of the Mortgage Note; and (6) the Mortgaged
Property is located in a jurisdiction in which the use of leasehold estates in
transferring ownership in residential properties is a widely accepted practice;

            (y) None of the Mortgage Loans are classified as "high cost"
Mortgage Loans under Section 32 of the Home Ownership and Equity Protection Act
of 1994 as amended or any comparable state law;

            (z) With respect to each Mortgage Loan that has a Prepayment
Penalty, each such Prepayment Penalty shall be enforceable, and each Prepayment
Penalty shall be permitted pursuant to federal, state and local law. Each such
Prepayment Penalty is in an amount less than or equal to the maximum amount
permitted under applicable law. Each such Prepayment Penalty actually charged to
the related borrower is in accordance with the Prepayment Penalty matrices set
forth in Exhibit R;

            (aa) Each Mortgage Loan is a "qualified mortgage" within the meaning
of Section 860G of the Code and Treas. Reg. ss.1.860G-2;

            (bb) No Mortgage Loan is a "high cost" loan as defined under any
federal, state or local law applicable to such Mortgage Loan at the time of its
origination;

            (cc) No Mortgage Loan is serviced by the Trustee or an affiliate of
the Trustee; and

            (dd) In addition to the foregoing representations and warranties
made in subparagraphs (a) through (cc) above, the Depositor further represents
and warrants upon delivery of the Group I Mortgage Loans, as to each, that:

            (i) No mortgage loan is covered by the Home Ownership and Equity
      Protection Act of 1994;

            (ii) With respect to each Group I Mortgage Loan, none of the
      proceeds of such Mortgage Loan were used to finance single-premium credit
      life insurance policies;

            (iii) With respect to each Group I Mortgage Loan, the Servicer has
      furnished accurate and complete information on the related borrower credit
      files to Equifax, Experian and Trans Union Credit Information Company, in
      accordance with the Fair Credit Reporting Act and its implementing
      regulations;

            (iv) The unpaid principal balance of each Group I Mortgage Loan does
      not exceed the applicable maximum original loan amount limitations with
      respect to first lien one- to four-family residential mortgage loans as
      set forth in the Freddie Mac Selling Guide;

            (v) With respect to each Group I Mortgage Loan that has a Prepayment
      Penalty, no such Prepayment Penalty may be imposed for a term in excess of
      five (5) years with respect to Mortgage Loans originated prior to October
      1, 2002 and three (3) years with respect to Mortgage Loans originated on
      or after October 1, 2002;

            (vi) No Group I Mortgage Loan is a "high-cost," "high-cost home,"
      "covered" (excluding home loans defined as "covered home loans" pursuant
      to clause (1) of the definition of that term in the New Jersey Home
      Ownership Security Act of 2002), "high-risk home" or "predatory" loan
      under any applicable federal, state or local predatory or abusive lending
      law; and

            (vii) With respect to any Group I Mortgage Loan originated on or
      after August 1, 2004, neither the related Mortgage nor the related
      Mortgage Note requires the borrower to submit to arbitration to resolve
      any dispute arising out of or relating in any way to the mortgage loan
      transaction.

            Notwithstanding the foregoing, no representations or warranties are
made by the Depositor as to the environmental condition of any Mortgaged
Property; the absence, presence or effect of hazardous wastes or hazardous
substances on any Mortgaged Property; any casualty resulting from the presence
or effect of hazardous wastes or hazardous substances on, near or emanating from
any Mortgaged Property; the impact on Certificateholders of any environmental
condition or presence of any hazardous substance on or near any Mortgaged
Property; or the compliance of any Mortgaged Property with any environmental
laws, nor is any agent, person or entity otherwise affiliated with the Depositor
authorized or able to make any such representation, warranty or assumption of
liability relative to any Mortgaged Property. In addition, no representations or
warranties are made by the Depositor with respect to the absence or effect of
fraud in the origination of any Mortgage Loan.

            It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the respective Owner
Mortgage Files (and, if applicable, Retained Mortgage Files) to the Custodian
and shall inure to the benefit of the Trustee notwithstanding any restrictive or
qualified endorsement or assignment.

            Section 2.05 Representations, Warranties and Covenants of the
Servicer. The Servicer hereby represents, warrants and covenants to the Trustee,

      and validly existing in good standing under the laws of the United States
      and has all licenses necessary to carry on its business as now being
      conducted, except for such licenses, certificates and permits the absence
      of which, individually or in the aggregate, would not have a material
      adverse effect on the ability of the Servicer to conduct its business as
      it is presently conducted, and is licensed, qualified and in good standing
      in the states where the Mortgaged Property is located if the laws of such
      state require licensing or qualification in order to conduct business of
      the type conducted by the Servicer or to ensure the enforceability or
      validity of each Mortgage Loan; the Servicer has the power and authority
      to execute and deliver this Agreement and to perform in accordance
      herewith; the execution, delivery and performance of this Agreement
      (including all instruments of transfer to be delivered pursuant to this
      Agreement) by the Servicer and the consummation of the transactions

      term or provision of, or conflict with or constitute a default under or
      result in the acceleration of any obligation under, any agreement,
      indenture or loan or credit agreement or other instrument to which the
      Servicer or its property is subject, or result in the violation of any

      Mac eligibility requirements or which would require notification to either
      Fannie Mae or Freddie Mac;

            (iv) This Agreement, and all documents and instruments contemplated
      hereby which are executed and delivered by the Servicer, constitute and
      will constitute valid, legal and binding obligations of the Servicer,

      individually or in the aggregate, may result in any material adverse
      change in the business, operations, financial condition, properties or
      assets of the Servicer, or in any material impairment of the right or
      ability of the Servicer to carry on its business substantially as now
      conducted, or in any material liability on the part of the Servicer, or
      that would draw into question the validity or enforceability of this
      Agreement or of any action taken or to be taken in connection with the
      obligations of the Servicer contemplated herein, or that would be likely
      to impair materially the ability of the Servicer to perform under the
       terms of this Agreement;

      for such consents, approvals, authorizations and orders, if any, that have
      been obtained;

            (viii) No information in this Agreement provided by the Servicer nor

      omit to state a material fact necessary in order to make the statements
      contained therein, in light of the circumstances under which they were
      made, not misleading;

      the Servicer that would be material to Certificateholders;

            (xi) Except as otherwise disclosed in the Prospectus, the Servicer
      is not aware and has not received notice that any default, early
      amortization or other performance triggering event has occurred as to any
      other securitization due to any act or failure to act of the Servicer
      under such securitization;

            (xii) Except as otherwise disclosed in the Prospectus, the Servicer

            It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Custodian and shall inure to the benefit of the Trustee, the
Depositor, the Securities Administrator and the Certificateholders. Upon
discovery by any of the Depositor, the Servicer, the Securities Administrator or
the Trustee of a breach of any of the foregoing representations, warranties and
covenants which materially and adversely affects the value of any Mortgage Loan,
Prepayment Penalty or the interests therein of the Certificateholders, the party
discovering such breach shall give prompt written notice (but in no event later
than two Business Days following such discovery) to the other parties hereto.

            Upon discovery by any of the Depositor, the Servicer, the Securities
Administrator or the Trustee of a breach of any of the representations and
warranties set forth in this Section 2.05, the party discovering such breach
shall give prompt written notice, which shall not exceed two days, to the other
parties. The Securities Administrator shall consult with the Depositor to
determine if any such breach is material and any breach determined by the
Depositor to be material shall be included by the Securities Administrator on
the next Distribution Date Statement prepared pursuant to Section 4.06.

            Section 2.06 Representations and Warranties of the Depositor. The
Depositor represents and warrants to the Trust and the Trustee on behalf of the
Certificateholders and to the Servicer and Securities Administrator as follows:

            (i) This agreement constitutes a legal, valid and binding obligation
      of the Depositor, enforceable against the Depositor in accordance with its
      terms, except as enforceability may be limited by applicable bankruptcy,
      insolvency, reorganization, moratorium or other similar laws now or
      hereafter in effect affecting the enforcement of creditors' rights in
      general and except as such enforceability may be limited by general
      principles of equity (whether considered in a proceeding at law or in

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

            Section 3.01 Servicer to Act as Servicer. The Servicer, as
independent contract servicer, shall service and administer the Mortgage Loans
in accordance with this Agreement and the normal and usual standards of practice
of sub-prime mortgage servicers servicing similar mortgage loans in the same
respective jurisdictions as the Mortgaged Properties, and shall have full power
and authority, acting alone, to do or cause to be done any and all things in
connection with such servicing and administration which the Servicer may deem
necessary or desirable and consistent with the terms of this Agreement (the
"Servicing Standards").

            Consistent with the terms of this Agreement, the Servicer may waive,
modify or vary any term of any Mortgage Loan or consent to the postponement of
strict compliance with any such term or in any manner grant indulgence to any
Mortgagor if in the Servicer's reasonable determination such waiver,
modification, postponement or indulgence is not materially adverse to the
Certificateholders; provided, however, that the Servicer shall not make future
advances and (unless the Mortgagor is in default with respect to the Mortgage
Loan or such default is, in the judgment of the Servicer, reasonably
foreseeable) the Servicer shall not permit any modification with respect to any
Mortgage Loan that would (i) change the Mortgage Interest Rate, defer or forgive
the payment thereof of any principal or interest payments, reduce the
outstanding principal amount (except for actual payments of principal) or extend
the final maturity date with respect to such Mortgage Loan, (ii) affect
adversely the status of any REMIC created hereunder as a REMIC or (iii) cause
any REMIC created hereunder to be subject to a tax on "prohibited transactions"
or "contributions" pursuant to the REMIC Provisions. Notwithstanding the
foregoing, the Servicer shall not permit any modification with respect to any
Mortgage Loan that would both (x) effect an exchange or reissuance of such
Mortgage Loan under Section 1.860G-2(b) of the Treasury Regulations and (y)
cause any REMIC constituting part of the Trust Fund to fail to qualify as a
REMIC under the Code or the imposition of any tax on "prohibited transactions"
or "contributions" after the Startup Day under the REMIC Provisions. Without
limiting the generality of the foregoing, the Servicer shall continue, and is
hereby authorized and empowered to execute and deliver on behalf of itself and
the Trustee, all instruments of satisfaction or cancellation, or of partial or
full release, discharge and all other comparable instruments, with respect to
the Mortgage Loans and with respect to the Mortgaged Properties. The Servicer
shall make all required Servicing Advances and shall service and administer the
Mortgage Loans in accordance with Applicable Regulations, and shall provide to
the Mortgagor any reports required to be provided to them thereby. By the
execution of this Agreement, the Trustee hereby grants to the Servicer, a power
of attorney to enable the Servicer to carry out its servicing and administrative
duties hereunder; provided, however, that the Trustee shall not be held liable
for any misuse of any such power of attorney by the Servicer. Notwithstanding
anything contained herein to the contrary, the Servicer shall not, without the
Trustee's written consent: (i) initiate any action, suit or proceeding solely
under the Trustee's name without indicating the Servicer's representative
capacity; or (ii) take any action with the intent to cause, and that actually
causes, the Trustee to be registered to do business in any state.

            In servicing and administering the Mortgage Loans, the Servicer
shall employ procedures including collection procedures and exercise the same
care that it customarily employs and exercises in servicing and administering
mortgage loans for its own account giving due consideration to accepted mortgage
servicing practices of prudent lending institutions and the Certificateholders'
reliance on the Servicer.

            Notwithstanding anything in this Agreement to the contrary, in the
event of a voluntary Principal Prepayment in full of a Mortgage Loan, the
Servicer may not waive any Prepayment Penalty or portion thereof required by the
terms of the related Mortgage Note unless (i)(a) the Servicer determines that
such waiver is standard and customary in servicing similar mortgage loans, (b)
such waiver relates to a default or a reasonably foreseeable default and (c)
would, in the reasonable judgment of the Servicer, maximize recovery of
Liquidation Proceeds for such Mortgage Loan, taking into account the value of
such Prepayment Penalty, or (ii) the enforceability thereof is limited (1) by
bankruptcy, insolvency, moratorium, receivership, or other similar law relating
to creditors' rights generally or (2) due to acceleration in connection with a
foreclosure or other involuntary payment. If the Servicer has waived or does not
collect all or a portion of a Prepayment Penalty relating to a voluntary
Principal Prepayment in full due to any action or omission of the Servicer,
other than as provided above, the Servicer shall, on the date on which the
Principal Prepayment in full is remitted to the Securities Administrator,
deliver to the Securities Administrator the Servicer Prepayment Penalty Amount
with respect to such Mortgage Loan for distribution in accordance with the terms
of this Agreement.

            In the event that a Prepayment Penalty due with respect to any
Mortgage Loan is not timely received by the Servicer, the Servicer shall use
commercially reasonable efforts to determine whether the Originator is obligated
to pay a related Originator Prepayment Penalty Payment Amount, and if the
Servicer determines that a Originator Prepayment Penalty Payment Amount is due,
the Servicer shall promptly notify the Originator, and the Servicer shall
enforce the Originator's obligations as set forth in the Mortgage Loan Purchase
Agreement to pay any such Originator Prepayment Penalty Payment Amounts and, to
the extent that such amounts are received by the Servicer, shall cause such
amounts to be deposited into the Collection Account within one Business Day of
receipt.

            Section 3.02 Collection of Mortgage Loan Payments. Continuously from
the date hereof until the principal and interest on all Mortgage Loans are paid
in full or as long as the Mortgage Loan remains subject to this Agreement, the
Servicer will diligently collect all payments due under each Mortgage Loan when
the same shall become due and payable and shall, to the extent such procedures
shall be consistent with the Servicing Standards and Applicable Regulations,
follow such collection procedures as it follows with respect to mortgage loans
comparable to the Mortgage Loans and held for its own account. Further, where
applicable, the Servicer will take special care in ascertaining and estimating
annual Escrow Payments that, as provided in the Escrow Agreement, will become
due and payable to that end that the installments payable by the Mortgagors will
be sufficient to pay such charges as and when they become due and payable.

            Section 3.03 Realization Upon Defaulted Mortgage Loans. In the event
that any payment due under any Mortgage Loan is not paid when the same becomes
due and payable, or in the event the Mortgagor fails to perform any other
covenant or obligation under the Mortgage Loan and such failure continues beyond
any applicable grace period, the Servicer shall take such action as it shall
deem to be in the best interest of the Certificateholders.

            In connection with a foreclosure or other conversion, the Servicer
shall exercise such rights and powers vested in it hereunder and use the same
degree of care and skill in its exercise as it would exercise or use under the
circumstances in the conduct of its own affairs and consistent with Applicable
Regulations and the Servicing Standards, including, without limitation,
advancing funds for the payment of taxes and insurance premiums with respect to
first lien Mortgage Loans.

            Notwithstanding the foregoing provisions of this Section 3.03, with
respect to any Mortgage Loan as to which the Servicer has received actual notice
of, or has actual knowledge of, the presence of any toxic or hazardous substance
on the related Mortgaged Property, the Servicer shall not either (i) obtain
title to such Mortgaged Property as a result of or in lieu of foreclosure or
otherwise, or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged Property if, as a result of any such action, the
Trust would be considered to hold title to, to be a mortgagee-in-possession of,
or to be an owner or operator of such Mortgaged Property within the meaning of
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended from time to time, or any comparable law, unless the Servicer
has also previously determined, based on its reasonable judgment and a report
prepared by a Person who regularly conducts environmental audits using customary
industry standards, stating that:

            A. such Mortgaged Property is in compliance with applicable
environmental laws or, if not, that it would be in the best economic interest of
the Certificateholders to take such actions as are necessary to bring the
Mortgaged Property into compliance therewith; and

            B. there are no circumstances present at such Mortgaged Property
relating to the use, management or disposal of any hazardous substances,
hazardous materials, hazardous wastes, or petroleum-based materials for which
investigation, testing, monitoring, containment, clean-up or remediation could
be required under any federal, state or local law or regulation, or that if any
such materials are present for which such action could be required, that it
would be in the best economic interest of the Certificateholders to take such
actions with respect to the affected Mortgaged Property.

            Notwithstanding the foregoing, if such environmental audit reveals,
or if the Servicer has actual knowledge or notice, that such Mortgaged Property
contains such wastes or substances, the Servicer shall not foreclose or accept a
deed in lieu of foreclosure.

            The cost of the environmental audit report contemplated by this
Section 3.03 shall be advanced by the Servicer, subject to the Servicer's right
to be reimbursed therefor from the Collection Account as provided in Section
3.05(ii).

            If the Servicer determines, as described above, that it is in the
best economic interest of the Certificateholders to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes, or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Certificateholders. The cost of any such compliance,
containment, cleanup or remediation shall be advanced by the Servicer, subject
to the Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.05(ii).

            Section 3.04 Collection Account, Distribution Account and Reserve
Account. (a) The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan separate and apart from any of its own
funds and general assets and shall establish and maintain one or more accounts
(such account or accounts, the "Collection Account"). Each Collection Account
shall be an Eligible Account.

            The Servicer shall deposit in the Collection Account within three
Business Days of receipt, and retain therein, the following payments and
collections received or made by it after the applicable Cut-off Date with
respect to the Mortgage Loans, without duplication:

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

            (ii) all payments on account of interest on the Mortgage Loans
      adjusted to the Mortgage Interest Rate less the Servicing Fee Rate;

            (iii) all Net Liquidation Proceeds and Subsequent Recoveries;

            (iv) all Insurance Proceeds including amounts required to be
      deposited pursuant to Section 3.10, other than proceeds to be held in the
      Escrow Account and applied to the restoration or repair of the Mortgaged
      Property or released to the Mortgagor in accordance with the Servicer's
      normal servicing procedures, the loan documents or applicable law;

            (v) all Condemnation Proceeds affecting any Mortgaged Property which
      are not released to the Mortgagor in accordance with the Servicer's normal
      servicing procedures, the loan documents or applicable law;

            (vi) any amounts required to be deposited by the Servicer in
      connection with any REO Property pursuant to Section 3.13;

            (vii) all Prepayment Penalties collected by the Servicer in
      connection with the voluntary Principal Prepayment in full of any of the
      Mortgage Loans, all Originator Prepayment Penalty Payment Amounts paid by
      the Originator and all Servicer Prepayment Penalty Payment Amounts
      required to be paid by the Servicer pursuant to Section 3.01 in connection
      with any such Principal Prepayment; and

            (viii) all amounts required to be deposited by the Servicer pursuant
      to Section 2.03.

            Any interest paid on funds deposited in the Collection Account,
subject to Section 3.23, shall accrue to the benefit of the Servicer and the
Servicer shall be entitled to retain and withdraw such interest from the
Collection Account pursuant to Section 3.05(v). The foregoing requirements for
deposit from the Collection 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, bad check fees, prepayment penalties that are
not Prepayment Penalties, Originator Prepayment Penalty Payment Amounts or
Servicer Prepayment Penalty Payment Amounts, assumption fees and other similar
fees need not be deposited by the Servicer in the Collection Account. Amounts
deposited into the Collection Account in error may be withdrawn at any time.

            (b) On behalf of the Trust Fund, the Securities Administrator shall
establish and maintain one or more accounts (such account or accounts, the
"Distribution Account"), on behalf of the Trustee, held in trust for the benefit
of the Certificateholders. On behalf of the Trust Fund, the Servicer shall
deliver (or cause the Originator to deliver in the case of clause (iii) below)
to the Securities Administrator in immediately available funds for deposit in
the Distribution Account by 1:00 p.m. New York City time on the Servicer
Remittance Date, (i) that portion of the Available Funds (calculated without
regard to the references in the definition thereof to amounts that may be
deposited to the Distribution Account from a different source as provided
herein) then on deposit in the Collection Account, (ii) the amount of all
Prepayment Penalties collected by the Servicer in connection with the voluntary
Principal Prepayment in full of any of the Mortgage Loans then on deposit in the
Collection Account (other than any such Prepayment Penalties received after the
related Prepayment Period), (iii) any Originator Prepayment Penalty Payment
Amount or Servicer Prepayment Penalty Payment Amount that became due during the
related Prepayment Period and (iv) amounts reimbursable or payable to the
Trustee pursuant to Section 7.01 and Section 8.05 and amounts reimbursable or
payable to the Securities Administrator pursuant to Section 8.05 or Section
9.01(c). These amounts may be sent via a single combined wire transfer. Except
as otherwise provided in Section 3.04(f), amounts in the Distribution Account
shall be deemed to be held on behalf of the related REMICs in accordance with
the REMIC distributions set forth in Section 4.08. The Securities Administrator
may, from time to time, withdraw from the Distribution Account for the following
purposes:

            (i) to pay to itself and to the Trustee any amounts owed to itself
      and the Trustee pursuant to Section 8.05, any amounts owed to itself
      pursuant to Section 9.01(c) and any amounts owed to the Trustee pursuant
      to Section 7.01;

            (ii) to pay to itself as compensation any interest earned on funds
      in the Distribution Account (all such interest to be withdrawn monthly on
      each Distribution Date); and

            (iii) to clear and terminate the Distribution Account upon the
      termination of this Agreement.

            (c) Funds in the Collection Account and the Distribution Account may
be invested in Permitted Investments in accordance with the provisions set forth
in Section 3.23. The Servicer shall give notice to the Securities Administrator
(and the Securities Administrator shall give such notice to the Trustee) of the
location of the Collection Account maintained by it when established upon
request and prior to any change thereof. The Securities Administrator shall give
notice to the Servicer, the Trustee and the Depositor of the location of the
Distribution Account when established and prior to any change thereof.

            (d) In the event the Servicer shall deliver to the Securities
Administrator for deposit in the Distribution Account any amount not required to
be deposited therein, it may at any time request that the Securities
Administrator withdraw such amount from the Distribution Account and remit to
the Servicer any such amount, any provision herein to the contrary
notwithstanding. In addition, the Servicer shall deliver to the Securities
Administrator from time to time for deposit, and the Securities Administrator
shall so deposit, in the Distribution Account in respect of REMIC 1:

            (i) any Advances, as required pursuant to Section 4.07;

            (ii) any Stayed Funds, as soon as permitted by the federal
      bankruptcy court having jurisdiction in such matters;

            (iii) any Prepayment Penalties or amounts in connection with the
      waiver of such Prepayment Penalties, in each case required to be deposited
      pursuant to Section 3.01;

            (iv) any amounts required to be deposited in the Distribution
      Account pursuant to Sections 2.03, 3.04, 3.16, 3.23 or 4.07; and

            (v) any amounts required to be deposited by the Servicer pursuant to
      Section 3.11 in connection with the deductible clause in any blanket
      hazard insurance policy, such deposit being made from the Servicer's own
      funds, without reimbursement therefor.

            (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source,
the Securities Administrator shall, unless such funds have been received from
the Servicer, notify the Servicer of such receipt and deposit such funds in the
Distribution Account, subject to withdrawal thereof as permitted hereunder. In
addition, the Securities Administrator shall deposit in the Distribution Account
any amounts required to be deposited pursuant to Section 3.23(b) in connection
with losses realized on Permitted Investments with respect to funds held in the
Distribution Account.

            (f) Any Prepayment Penalties, Originator Prepayment Penalty Payment
Amounts and Servicer Prepayment Penalty Payment Amounts deposited pursuant to
Section 3.04(a)(vii) shall not be assets of any REMIC created hereunder, but
shall be considered assets of the Grantor Trust held by the Securities
Administrator, on behalf of the Trustee, for the benefit of the Class P
Certificateholders. In addition, any Cap Carryover Amounts that are paid with
respect to the Class A or Class M Certificates will be treated as first having
been distributed with respect to the Class CE Certificates and then having been
paid outside of the REMICs to the Class A or Class M Certificateholders.

            (g) The Securities Administrator shall establish and maintain the
Reserve Account, held in trust for the benefit of the Holders of the Class M-1,
Class M-2, Class M-3, Class M-4 and Class M-5, Class M-6, Class M-7, Class M-8,
Class M-9, Class M-9, Class M-10, Class M-11, Class M-12 and Class M-13
Certificates. The Securities Administrator shall deposit in the Reserve Account
on the date received by it, any Yield Maintenance Agreement Payment received
from the Yield Maintenance Agreement Provider for the related Distribution Date.
On each Distribution Date, the Securities Administrator shall withdraw from the
Reserve Account any Yield Maintenance Agreement Payment on deposit and apply it
in the following order of priority:

            (i) to the Class M Certificates, from the Reserve Account, in each
      case only up to the Cap Amount for the related Class, any Cap Carryover
      Amounts for such Classes for such Distribution Date, distributed
      concurrently, to the Class M-1, Class M-2, Class M-3, Class M-4, Class
      M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class M-10, Class M-11,
      Class M-12 and Class M-13 Certificates;

            (ii) to the Class M Certificates, from the Reserve Account, without
      regard to the Cap Amount for the related Class, any remaining unpaid Cap
      Carryover Amounts for such Classes for such Distribution Date (after
      distributions pursuant to clause (i) above), distributed concurrently, to
      the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6,
      Class M-7, Class M-8, Class M-9, Class M-10, Class M-11, Class M-12 and
      Class M-13 Certificates, pro rata, based on their respective remaining Cap
      Carryover Amounts; and

            (iii) to the Class CE Certificates, any remaining amount on deposit
       in the Reserve Account.

            (h) The Securities Administrator shall account for the Reserve
Account as an asset of a grantor trust under subpart E, part I of subchapter J
of the Code and not an asset of any REMIC created pursuant to this Agreement.
The beneficial owner of the Reserve Account is the Class CE Certificateholder.
For all federal tax purposes, amounts transferred or reimbursed by REMIC A to
the Reserve Account shall be treated as distributions by the Securities
Administrator to the Class CE Certificateholder.

            (i) Any Cap Carryover Amounts paid by the Securities Administrator
pursuant to Section 3.04(g) to the Regular Certificates (other than the Class CE
Certificates) shall be accounted for by the Securities Administrator as amounts
paid first to the Class CE Certificates and then to the respective Class or
Classes of Regular Certificates (other than the Class CE Certificates). In
addition, the Securities Administrator shall account for the Regular
Certificates' (other than the Class CE Certificates) rights to receive payments
of Cap Carryover Amounts as rights in a limited recourse interest rate cap
contract written by the Class CE Certificates in favor of the Regular
Certificates (other than the Class CE Certificates).

             (j) For federal tax return and information reporting, the right of
the Holders of the Regular Certificates (other than the Class CE Certificates)
to receive payments under the Yield Maintenance Agreement in respect of the
Yield Maintenance Agreement Payments shall be assigned a value of zero.

            Section 3.05 Permitted Withdrawals From the Collection Account. The
Servicer may, from time to time, withdraw from the Collection Account for the
following purposes:

            (i) to remit to the Securities Administrator for deposit in the
      Distribution Account the amounts required to be so remitted pursuant to
      Section 3.04(b) or permitted to be so remitted pursuant to the first
      sentence of Section 3.04(d);

            (ii) first, to the extent the Servicer has not previously reimbursed
      the Trustee pursuant to Section 4.07(e), to reimburse the Trustee for any
      unreimbursed Advances made by the Trustee and second, to reimburse itself
      for any unreimbursed Advances and Servicing Advances; the Servicer's right
      to reimburse itself and the Trustee pursuant to this subclause (ii) being
      limited to amounts received on the related Mortgage Loan which represent
      payments of (a) principal and/or interest respecting which any such
      Advance was made or (b) Condemnation Proceeds, Insurance Proceeds or
      Liquidation Proceeds respecting which any such Servicing Advance was made;

            (iii) first, to the extent the Servicer has not previously
       reimbursed the Trustee pursuant to Section 4.07(e), to reimburse the
      Trustee for any unreimbursed Advances made by the Trustee and second to
      reimburse itself for any unreimbursed Servicing Advances, any unpaid
      Servicing Fees and for unreimbursed Advances, in each case, to the extent
      that such amounts are deemed to be Nonrecoverable Advances, and to
      reimburse itself and the Trustee for such amounts to the extent that such
      amounts are nonrecoverable from the disposition of REO Property pursuant
      to Section 3.03 or Section 3.13 hereof;

            (iv) to reimburse itself for any amounts paid or expenses incurred
      pursuant to Section 3.03 (and not otherwise previously reimbursed);

            (v) to pay to itself as servicing compensation (a) any interest
      earned on funds in the Collection Account (all such interest to be
      withdrawn monthly not later than each Servicer Remittance Date) and (b)
      the Servicing Fee from that portion of any payment or recovery as to
      interest to a particular Mortgage Loan to the extent not retained pursuant
      to Section 3.04(ii);

            (vi) to reimburse itself for any amounts paid pursuant to Section
      6.03 (and not otherwise previously reimbursed);

            (vii) to reimburse the Servicer (if the Servicer is not an Affiliate
      of the repurchasing party), the Securities Administrator or the Trustee,
      as the case may be, for enforcement expenses reasonably incurred in
      respect of the breach or defect giving rise to the purchase obligation
      under Section 2.03 of this Agreement that were included in the Purchase
      Price of the Mortgage Loan, including any expenses arising out of the
      enforcement of the purchase obligation;

            (viii) to reimburse the Depositor or the Servicer for expenses and
      costs reimbursable to them pursuant to Section 3.24(b); and

            (ix) to clear and terminate the Collection Account upon the
      termination of this Agreement.

            The foregoing requirements for withdrawal from the Collection
Account shall be exclusive. In the event the Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from the Collection Account, any provision herein
to the contrary notwithstanding.

            Section 3.06 Establishment of Escrow Accounts; Deposits in Escrow
Accounts. The Servicer shall segregate and hold all funds collected and received
pursuant to each Mortgage Loan which constitute Escrow Payments separate and
apart from any of its own funds and general assets and shall establish and
maintain one or more Escrow Accounts, in the form of time deposit or demand
accounts. A copy of such letter agreement shall be furnished to the Trustee upon
request. The Escrow Account shall be an Eligible Account.

            The Servicer shall deposit in the Escrow Account or Accounts within
three Business Days of receipt, and retain therein, (i) all Escrow Payments
collected on account of the Mortgage Loans, for the purpose of effecting timely
payment of any such items as required under the terms of this Agreement, and
(ii) all Insurance Proceeds which are to be applied to the restoration or repair
of any Mortgaged Property. The Servicer shall make withdrawals therefrom only to
effect such payments as are required under this Agreement, and for such other
purposes as shall be set forth in, or in accordance with, Section 3.07. The
Servicer shall be entitled to retain any interest paid on funds deposited in the
Escrow Account by the depository institution other than interest on escrowed
funds required by law to be paid to the Mortgagor and, to the extent required by
the related Mortgage Loan or Applicable Regulations, the Servicer shall pay
interest on escrowed funds to the Mortgagor notwithstanding that the Escrow
Account is non-interest bearing or that interest paid thereon is insufficient
for such purposes.

            Section 3.07 Permitted Withdrawals From Escrow Account. Withdrawals
from the Escrow Account may be made by the Servicer (i) to effect timely
payments of Escrow Payments, (ii) to reimburse the Servicer for any Servicing
Advance made by the Servicer with respect to a related Mortgage Loan but only
from amounts received on the related Mortgage Loan which represent late payments
or Late Collections of Escrow Payments thereunder, (iii) to refund to the
Mortgagor any funds as may be determined to be overages, (iv) for transfer to
the Collection Account in accordance with the terms of this Agreement, (v) for
application to restoration or repair of the Mortgaged Property, (vi) to pay to
the Servicer, or to the Mortgagor to the extent required by the related Mortgage
Loan or Applicable Regulations, any interest paid on the funds deposited in the
Escrow Account, (vii) to clear and terminate the Escrow Account on the
termination of this Agreement, or (viii) to transfer to the Collection Account
any Insurance Proceeds. As part of its servicing duties, the Servicer shall pay
to the Mortgagor interest on funds in the Escrow Account, to the extent required
by the related Mortgage Loan or Applicable Regulations, and to the extent that
interest earned on funds in the Escrow Account is insufficient, shall pay such
interest from its own funds, without any reimbursement therefor.

            In the event the Servicer shall deposit in the Escrow Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from the Escrow Account, any provision herein to the contrary
notwithstanding.

            Section 3.08 Payment of Taxes, Insurance and Other Charges;
Collections Thereunder; Primary Mortgage Insurance. (a) With respect to each
Mortgage Loan subject to an Escrow Agreement, the Servicer shall maintain
accurate records reflecting the status of taxes, which are or may become a lien
upon the Mortgaged Property and the status of fire, flood (if applicable) and
hazard insurance coverage and shall obtain, from time to time, all bills for the
payment of such charges (including renewal premiums) and shall effect payment
thereof prior to the applicable penalty or termination date and at a time
appropriate for securing maximum discounts allowable, employing for such purpose
deposits of the Mortgagor in the Escrow Account which shall have been estimated
and accumulated by the Servicer in amounts sufficient for such purposes, as
allowed under the terms of the Escrow Agreement or Applicable Regulations. To
the extent that a Mortgage Loan is not subject to an Escrow Agreement, the
Servicer shall determine that any such payments are made by the Mortgagor. The
Servicer assumes full responsibility for the payment of all such bills and shall
effect payments of all such bills irrespective of the Mortgagor's faithful
performance in the payment of same or the making of the Escrow Payments and
shall make Servicing Advances from its own funds to effect such payments.

            (b) For any Mortgage Loan with a Loan-to-Value Ratio at origination
of greater than 80%, if the Mortgage Loan Schedule indicates that such Mortgage
Loan has primary mortgage insurance, the Servicer shall maintain coverage under
a primary mortgage insurance policy until the Loan-to-Value Ratio on any such
Mortgage Loan is reduced to 78% or lower as a result of principal payments on
such Mortgage Loan or based upon an appraisal of the related Mortgaged Property
after the Closing Date. Notwithstanding anything to the contrary herein, the
Servicer shall be responsible for the payment of all primary mortgage insurance
premiums out of the Servicer's own funds, without any right to reimbursement
therefor. The Servicer shall not assign its obligation under any primary
mortgage insurance policy without the consent of each Rating Agency and the
related primary insurance policy provider. In the event that Wells Fargo Bank is
no longer Servicer hereunder, Wells Fargo Bank agrees to continue to pay all
primary mortgage insurance premiums for the Mortgage Loans.

            Section 3.09 Transfer of Accounts. The Servicer may transfer the
Collection Account or the Escrow Account to a different depository institution
from time to time. Upon such transfer, the Servicer shall deliver to the
Securities Administrator (and the Securities Administrator shall provide to the
Depositor and the Trustee), a certification or letter agreement, as the case may
be, as required pursuant to Sections 3.04 and 3.06.

            Section 3.10 Maintenance of Hazard Insurance. The Servicer shall
cause to be maintained for each Mortgage Loan fire and hazard insurance with
extended coverage as is customary in the area where the Mortgaged Property is
located in an amount which is at least equal to the lesser of (i) the amount
necessary to fully compensate for any damage or loss to the improvements which
are a part of such property on a replacement cost basis or (ii) the Principal
Balance of the Mortgage Loan, in each case in an amount not less than such
amount as is necessary to prevent the Mortgagor and/or the Mortgagee from
becoming a co-insurer. If the Mortgaged Property is in an area identified in the
Federal Register by the Flood Emergency Management Agency as having special
flood hazards and flood insurance has been made available, the Servicer will
cause to be maintained a flood insurance policy meeting the requirements of the
current guidelines of the Federal Insurance Administration with a generally
acceptable insurance carrier, in an amount representing coverage not less than
the least of (i) the Principal Balance of the Mortgage Loan, (ii) the maximum
insurable value of the improvements securing such Mortgage Loan or (iii) the
maximum amount of insurance which is available under the National Flood
Insurance Act of 1968, as amended. The Servicer shall also maintain on the REO
Property for the benefit of the Certificateholders, (x) fire and hazard
insurance with extended coverage in an amount which is at least equal to the
replacement cost of the improvements which are a part of such property and (y)
to the extent required and available under the Flood Disaster Protection Act of
1973, as amended, flood insurance in an amount as provided above. Any amounts
collected by the Servicer under any such policies other than amounts to be
deposited in the Escrow Account and applied to the restoration or repair of the
Mortgaged Property or REO Property, or released to the Mortgagor in accordance
with the Servicer's normal servicing procedures, shall be deposited in the
Collection Account, subject to withdrawal pursuant to Section 3.05. It is
understood and agreed that no earthquake or other additional insurance is
required to be maintained by the Servicer or the Mortgagor or maintained on
property acquired in respect of the Mortgage Loan, other than pursuant to such
Applicable Regulations as shall at any time be in force and as shall require
such additional insurance. All such policies shall be endorsed with standard
mortgagee clauses with loss payable to the Servicer and shall provide for at
least thirty days prior written notice of any cancellation, reduction in the
amount of or material change in coverage to the Servicer. The Servicer shall not
interfere with the Mortgagor's freedom of choice in selecting either his
insurance carrier or agent, provided, however, that the Servicer shall not
accept any such insurance policies from insurance companies unless such
companies currently reflect a general policy rating of B:VI or better in Best's
Key Rating Guide and are licensed to do business in the state wherein the
property subject to the policy is located.

            Section 3.11 Maintenance of Mortgage Impairment Insurance Policy. In
the event that the Servicer shall obtain and maintain a blanket policy issued by
an insurer that has a general policy rating of B:VI or better in Best's Key
Rating Guide insuring against hazard losses on all of the Mortgage Loans, then,
to the extent such policy provides coverage in an amount equal to the amount
required pursuant to Section 3.10 and otherwise complies with all other
requirements of Section 3.10, it shall conclusively be deemed to have satisfied
its obligations as set forth in Section 3.10, it being understood and agreed
that such policy may contain a deductible clause, in which case the Servicer
shall, in the event that there shall not have been maintained on the related
Mortgaged Property or REO Property a policy complying with Section 3.10, and
there shall have been a loss which would have been covered by such policy,
deliver to the Securities Administrator for deposit in the Distribution Account
the amount not otherwise payable under the blanket policy because of such
deductible clause, which amount shall not be reimbursable to the Servicer from
the Trust Fund. In connection with its activities as servicer of the Mortgage
Loans, the Servicer agrees to prepare and present, on behalf of the Trustee,
claims under any such blanket policy in a timely fashion in accordance with the
terms of such policy. Upon request of the Securities Administrator, the Servicer
shall cause to be delivered to the Custodian and the Securities Administrator a
certified true copy of such policy and a statement from the insurer thereunder
that such policy shall in no event be terminated or materially modified without
thirty days prior written notice to the Trustee.

            Section 3.12 Fidelity Bond, Errors and Omissions Insurance. The
Servicer shall maintain, at its own expense, a blanket fidelity bond (the
"Fidelity Bond") and an errors and omissions insurance policy, with broad
coverage with financially responsible companies on all officers, employees or
other persons acting in any capacity with regard to the Mortgage Loans to handle
funds, money, documents and papers relating to the Mortgage Loans. The Fidelity
Bond and errors and omissions insurance shall be in the form of the Mortgage
Banker's Blanket Bond and shall protect and insure the Servicer against losses,
including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such persons. Such Fidelity Bond shall also protect and insure
the Servicer against losses in connection with the failure to maintain any
insurance policies required pursuant to this Agreement and the release or
satisfaction of a Mortgage Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section 3.12 requiring the
Fidelity Bond and errors and omissions insurance shall diminish or relieve the
Servicer from its duties and obligations as set forth in this Agreement. The
minimum coverage under any such bond and insurance policy shall be in an amount
acceptable to Fannie Mae or Freddie Mac. Upon request of the Trustee, the
Servicer shall cause to be delivered to the Trustee a certified true copy of the
Fidelity Bond and errors and omissions insurance policy and a statement from the
surety and the insurer that such Fidelity Bond and errors and omissions
insurance policy shall in no event be terminated or materially modified without
the acquisition of comparable coverage by the Servicer.

            Section 3.13 Title, Management and Disposition of REO Property. (a)
In the event that title to a Mortgaged Property is acquired in foreclosure or by
deed in lieu of foreclosure, the deed or certificate of sale shall be taken in
the name of the Trustee, on behalf of the Certificateholders, or in the event
the Trustee is not authorized or permitted to hold title to real property in the
state where the REO Property is located, or would be adversely affected under
the "doing business" or tax laws of such state by so holding title, the deed or
certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Servicer from an
attorney duly licensed to practice law in the state where the REO Property is
located. Any Person or Persons holding such title other than the Trustee shall
acknowledge in writing that such title is being held as nominee for the benefit
of the Trustee. Pursuant to the power of attorney granted in Section 3.01, the
Servicer is hereby authorized to acquire, transfer and dispose of any REO
Property taken in the name of the Trustee pursuant to this Section 3.13 without
further documentation of its authority as attorney in fact for the Trustee on
behalf of the Trust.

            (b) In the event that the Trust Fund acquires any REO Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end of
the third calendar year beginning after the year of its acquisition by the Trust
Fund for purposes of Section 860G(a)(8) of the Code or, at the expense of the
Trust Fund, request from the Internal Revenue Service, more than 60 days before
the day on which the above-mentioned grace period would otherwise expire, an
extension of the above-mentioned grace period, unless the Servicer obtains an
Opinion of Counsel, addressed and delivered to the Servicer and the Trustee, to
the effect that the holding by the Trust Fund of such REO Property subsequent to
such period will not: (i) result in the imposition of any tax on "prohibited
transactions" as defined in Section 860F of the Code; or (ii) cause any REMIC
constituting any part of the Trust Fund to fail to qualify as a REMIC at any
time that any Certificates are outstanding, in which case the Trust Fund may
continue to hold such REO Property (subject to any conditions contained in such
Opinion of Counsel). The Servicer shall be entitled to be reimbursed from the
Collection Account for any costs incurred in obtaining such Opinion of Counsel,
as provided in Section 3.05.

            Subject to compliance with applicable laws and regulations as shall
at any time be in force, and notwithstanding any other provisions of this
Agreement, no REO Property acquired by the Trust Fund shall be rented (or
allowed to continue to be rented) or otherwise used by or on behalf of the Trust
Fund in such a manner or pursuant to any terms that would: (i) cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code; or (ii) subject any REMIC constituting part of
the Trust Fund to the imposition of any federal income taxes on the income
earned from such REO Property, including any taxes imposed by reason of Sections
860F or 860G(c) of the Code, unless the Servicer has agreed to indemnify and
hold harmless the Trust Fund with respect to the imposition of any such taxes.

            The Servicer shall manage, conserve, protect and operate each REO
Property for the Certificateholders and the Trust Fund solely for the purpose of
its prompt disposition and sale in a manner which does not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by the related REMIC of
any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions. The Servicer shall cause each
REO Property to be inspected promptly upon the acquisition of title thereto and
possession thereof and shall cause each REO Property to be inspected at least
annually thereafter. The Servicer shall make or cause to be made a written or
electronic report of each such inspection. Such reports shall be retained in the
Mortgage File and copies thereof shall be forwarded by the Servicer to the
Trustee upon request. The Servicer shall attempt to sell the same (and may
temporarily rent the same) on such terms and conditions as the Servicer deems to
be in the best interest of the Certificateholders and the Trust Fund.

            With respect to each REO Property, the Servicer shall segregate and
hold all funds collected and received in connection with the operation of the
REO Property separate and apart from its own funds or general assets and shall
deposit or cause to be deposited, on a daily basis, within three Business Days
of receipt, into the Collection Account, all revenues received with respect to
the related REO Property and shall withdraw therefrom funds necessary for the
proper operation, management and maintenance of the REO Property, including the
cost of maintaining any hazard insurance pursuant to Section 3.10 hereof and the
fees of any managing agent acting on behalf of the Servicer.

            The Servicer shall furnish to the Securities Administrator and the
Trustee, on each Servicer Remittance Date, an operating statement for each REO
Property covering the operation of each REO Property for the previous month, if
applicable. Such operation statement shall be accompanied by such other
information as the Securities Administrator or the Trustee shall reasonably
request.

            The Servicer shall use its best efforts to dispose of the REO
Property as promptly as is practically consistent with protecting the
Certificateholders' interests.

            Each REO Disposition shall be carried out by the Servicer at such
price and upon such terms and conditions as the Servicer deems to be in the best
interest of the Certificateholders. If as of the date title to any REO Property
was acquired by the Servicer there were outstanding unreimbursed Servicing
Advances with respect to the REO Property, the Servicer, upon an REO Disposition
of such REO Property, shall be entitled to reimbursement for any related
unreimbursed Servicing Advances from proceeds received in connection with such
REO Disposition. The Servicer shall be entitled to an REO Disposition Fee upon
each REO Disposition, and may withhold and retain the REO Disposition Fee from
Liquidation Proceeds. The proceeds from the REO Disposition, net of any payments
to the Servicer as provided above, shall be deposited in the Collection Account
and shall be distributed to the Trust in the month following receipt thereof in
accordance with Section 4.01.

            Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

            Section 3.14 Due-on-Sale Clauses; Assumption and Substitution
Agreements. When a Mortgaged Property has been or is about to be conveyed by the
Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance
or prospective conveyance, exercise its rights to accelerate the maturity of the
related Mortgage Loan under any "due-on-sale" clause contained in the related
Mortgage or Mortgage Note; provided, however, that the Servicer shall not
exercise any such right if the "due-on-sale" clause, in the reasonable belief of
the Servicer, is not enforceable under applicable law. In such event, the
Servicer shall make reasonable efforts to enter into an assumption and
modification agreement 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 law or the Mortgage, the
Mortgagor remains liable thereon. If the foregoing is not permitted under
applicable law, the Servicer is authorized 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 Note. The Mortgage Loan, as assumed, shall conform in
all respects to the requirements, representations and warranties of this
Agreement. The Servicer shall notify the Trustee that any such assumption or
substitution agreement has been completed by forwarding to the Trustee (or the
Custodian, as the case may be) the original copy of such assumption or
substitution agreement (indicating the Mortgage File to which it relates) which
copy shall be added by the Trustee (or the Custodian, as the case may be) to the
related Mortgage File and which 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. The Servicer shall be responsible for recording any
such assumption or substitution agreements. Except as otherwise provided in
Section 3.01, in connection with any such assumption or substitution agreement,
the Monthly Payment on the related Mortgage Loan shall not be changed but shall
remain as in effect immediately prior to the assumption or substitution, the
stated maturity or outstanding principal amount of such Mortgage Loan shall not
be changed nor shall any required monthly payments of principal or interest be
deferred or forgiven. Any fee collected by the Servicer for consenting to any
such conveyance or entering into an assumption or substitution agreement shall
be retained by or paid to the Servicer as additional servicing compensation.

            Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any assumption of a
Mortgage Loan by operation of law or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

            Section 3.15 Duties of the Credit Risk Manager.

            For and on behalf of the Trust, the Credit Risk Manager shall
provide reports and recommendations as to loss mitigation activities concerning
Mortgage Loans that are past due, are in default, as to which there has been
commencement of foreclosure, as to which there has been forbearance in exercise
of remedies, as to which any obligor is the subject of bankruptcy, receivership,
or an arrangement of creditors, or which have become REO Properties. Such
reports and recommendations will be based upon information provided pursuant to
the Credit Risk Management Agreement. The Credit Risk Manager shall look solely
to the Servicer for all information and data (including loss and delinquency
information and data) and loan-level information and data relating to the
servicing of the Mortgage Loans.

            The Credit Risk Manager may be removed at any time by a vote of
Certificateholders holding Certificates evidencing at least 66 2/3% of the
aggregate Voting Interests of the Certificates. After any such termination, the
Credit Risk Manager shall have no further obligations hereunder, and shall no
longer be entitled to the Credit Risk Manager Fee.

            Section 3.16 Optional Purchases of 60+ Day Delinquent Loans. (a) The
Depositor may, at its option, purchase any 60+ Day Delinquent Loan or any
Mortgage Loan or REO Property for which the Servicer has accepted a deed in lieu
of foreclosure during the following time periods: (i) beginning on the first day
of the second month following the month in which the Servicer has reported that
it has initiated foreclosure proceedings with respect to such 60+ Day Delinquent
Loan, with such repurchase option expiring on the last day of such second
following month; (ii) beginning on the first day of the second month following
the month in which the Servicer has reported that such defaulted Mortgage Loan
has become an REO Property, with such repurchase option expiring on the last day
of such second following month; and (iii) beginning on the day on which the
Servicer accepts a contractual commitment by a third party to purchase the
Mortgaged Property related to the 60+ Day Delinquent Loan or REO Property, with
such repurchase option expiring on the earlier of the last day of the month in
which such contractual commitment was accepted by the Servicer or the day
immediately prior to the day on which the closing occurs with respect to such
third party purchase of the Mortgaged Property related to the 60+ Day Delinquent
Loan or REO Property.

            Prior to purchase pursuant to this Section 3.16, the Servicer shall
be required to continue to make monthly Advances pursuant to Section 4.07. The
Depositor shall not use any procedure in selecting Mortgage Loans to be
purchased which is materially adverse to the interests of the
Certificateholders. The Depositor shall purchase any such 60+ Day Delinquent
Loan or REO Property that it elects to purchase at a price equal to the Purchase
Price. The Purchase Price for the repurchased Mortgage Loan or REO Property
shall be deposited in the Collection Account, and the Trustee, upon receipt of
written certification from the Depositor of such deposit, shall release to, or
at the direction of, the Depositor, the related Mortgage File and shall execute
and deliver such instruments of transfer or assignment, 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 or REO Property released pursuant hereto and
the Trustee shall have no further responsibility with regard to such Mortgage
File.

            Section 3.17 Trustee to Cooperate; Release of Files. (a) Upon the
payment in full of any Mortgage Loan (including any liquidation of any Mortgage
Loan through foreclosure or otherwise, or the receipt by the Servicer of a
notification that payment in full will be escrowed in a manner customary for
such purposes), the Servicer shall confirm to the Trustee and the Securities
Administrator that all amounts required to be remitted to the Distribution
Account in connection with such Mortgage Loan have been so deposited, and the
Servicer shall deliver two copies of such Request for Release to the Custodian.
The Custodian shall, within five Business Days of its receipt of such a Request
for Release, release the related Owner Mortgage File (and Retained Mortgage
File, if applicable) to the Servicer, as requested by the Servicer. No expenses
incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Distribution Account.

            From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including but not limited to, collection under
any insurance policies, or to effect a partial release of any Mortgaged Property
from the lien of the Mortgage, the Servicer shall deliver to the Custodian two
copies of a Request for Release. The Custodian shall, within five Business Days,
release the related Owner Mortgage File (and Retained Mortgage File, if
applicable) to the Servicer. Any such Request for Release shall obligate the
Servicer to return the Owner Mortgage File (and Retained Mortgage File, if
applicable) to the Custodian by the twenty-first day following the release
thereof, unless (i) the Mortgage Loan has been liquidated and the Liquidation
Proceeds relating to the Mortgage Loan have been deposited in the Distribution
Account or (ii) the Owner Mortgage File (or Retained Mortgage File, if
applicable) or any documents contained therein 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 either judicially or non-judicially. Upon
receipt of two copies of a Request for Release stating that such Mortgage Loan
was liquidated and that all amounts received or to be received in connection
with such liquidation which are required to be deposited into the Distribution
Account have been so deposited, or that such Mortgage Loan has become an REO
Property, the Custodian shall amend its records.

             Upon the occurrence of the event specified in clause (ii) of the
preceding paragraph, the Trustee shall execute and deliver to the Servicer, as
directed by the Servicer, court pleadings, requests for trustee's sale or other
documents necessary to the foreclosure or trustee's sale in respect of a
Mortgaged Property or to any legal action brought to obtain judgment against any
Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment,
or to enforce any other remedies or rights provided by the Mortgage Note or
Mortgage or otherwise available at law or in equity. Each such direction shall
include a request that such pleadings or documents be executed by the Trustee
and a statement as to the reason such documents or pleadings are required and a
certification that the execution and delivery thereof by the Trustee will not
invalidate or otherwise affect the lien of the Mortgage, except for the
termination of such a lien upon completion of the foreclosure proceeding or
trustee's sale.

             (b) Subject to Section 3.01, the Servicer shall have the right to
accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, and (iii) removal, demolition or division of
properties subject to Mortgages. No application for approval shall be considered
by the Servicer unless: (w) either (A) it has received an Opinion of Counsel,
addressed to the Trustee (which opinion shall not be an expense of the Trustee
or the Trust Fund) that such sale, disposition, substitution, acquisition or
contribution will not affect adversely the status of any REMIC constituting part
of the Trust Fund as a REMIC or cause any REMIC constituting part of the Trust
Fund to be subject to a tax on "prohibited transactions" or "contributions"
pursuant to the REMIC Provisions or (B) other evidence satisfactory to the
Servicer; (x) the provisions of the related Mortgage Note and Mortgage have been
complied with; (y) the Loan-to-Value Ratio and debt-to-income ratio after any
release does not exceed the maximum Loan-to-Value Ratio and debt-to-income ratio
established in accordance with the underwriting standards of the Mortgage Loans;
and (z) the lien priority of the related Mortgage is not affected. Upon receipt
by the Trustee of a Servicing Officer's certificate setting forth the action
proposed to be taken in respect of a particular Mortgage Loan and certifying
that the criteria set forth in the immediately preceding sentence have been
satisfied, the Trustee shall execute and deliver to the Servicer the consent or
partial release so requested by, and furnished to it by, the Servicer. A
proposed form of consent or partial release, as the case may be, shall accompany
any Servicing Officer's certificate delivered by the Servicer pursuant to this
paragraph.

            Section 3.18 Servicing Compensation. As compensation for its
activities hereunder, the Servicer shall be entitled to retain the amount of the
Servicing Fee with respect to each Mortgage Loan (including REO Properties). The
Servicer shall be entitled to retain additional servicing compensation in the
form of release fees, bad check charges, assumption fees, modification or
extension fees, late payment charges, prepayment penalties that are not
Prepayment Penalties, Servicer Prepayment Penalty Payment Amounts, Originator
Prepayment Penalty Payment Amounts or REO Disposition Fees, or any other
service-related fees, Insurance Proceeds and Liquidation Proceeds not required
to be deposited in the Collection Account and similar items, to the extent
collected from Mortgagors. In addition, the Servicer shall be entitled to the
investment income on funds on deposit in the Collection Account.

            Section 3.19 Annual Statement as to Compliance. (a) The Securities
Administrator shall deliver in electronic format or otherwise make available to
the Depositor and the Servicer shall deliver in electronic form, or otherwise
make available to the Securities Administrator, and the Servicer shall cause
each Additional Servicer engaged by it to deliver, in electronic form, or
otherwise make available, to the Securities Administrator, the Trustee and each
Rating Agency on or before March 5 of each year or if such day is not a Business
Day, the next Business Day (with a 10 calendar day cure period, but in no event
later than March 15), commencing in March 200 , a copy of a certificate
(followed by a hard copy to the party or parties receiving such certificate
within 10 calendar days) in the form required by Item 1123 of Regulation AB, to
the effect that (i) an authorized officer of the Securities Administrator, the
Servicer or the Additional Servicer, as the case may be, has reviewed (or a
review has been made under his or her supervision of) such party's activities
under this Agreement or such other applicable agreement in the case of an
Additional Servicer, during the prior calendar year or portion thereof and (ii)
to the best of such officer's knowledge, based on such review, such party has
fulfilled all of its obligations under this Agreement or such other applicable
agreement in the case of an Additional Servicer, in all material respects
throughout the prior calendar year or portion thereof or, if there has been a
failure to fulfill any such obligation in any material respect, specifying each
such failure known to such officer and the nature and status thereof. If any of
the certificates delivered pursuant to this Section 3.19 disclose that there has
been a failure to fulfill any obligation in any material respect then the

      compliance with the Servicing Criteria applicable to it;

            (ii) a statement that such party used the Servicing Criteria
      applicable to it to assess compliance with the Servicing Criteria;

            (iii) such party's assessment of compliance with the Servicing
      Criteria applicable to it as of and for the preceding fiscal year,
      including, if there had been any material instance of noncompliance with
      the Servicing Criteria applicable to it, identifying each such failure and
      the nature and status thereof; and

            (iv) a statement that a registered public accounting firm has issued
      an attestation report on such party's assessment of compliance with the
      Servicing Criteria applicable to it as of and for the preceding fiscal
      year.

            No later than 30 days following the end of each fiscal year, the
Securities Administrator shall forward to the Depositor the name of each
Servicing Function Participant engaged by it and what Relevant Servicing
Criteria will be addressed in the report on assessment of compliance prepared by
such Servicing Function Participant. When the Securities Administrator submits
its assessments to the Depositor, it will also at such time include the
assessment (and attestation pursuant to Section 3.20(b)) of each Servicing
Function Participant engaged by it.

            No later than 30 days following the end of each fiscal year, each of
the Servicer, the Trustee and the Custodian (so long as the Custodian is not the
Securities Administrator) shall forward to the Securities Administrator the name
of each Servicing Function Participant engaged by it and what Relevant Servicing
Criteria will be addressed in the report on assessment of compliance prepared by
such Servicing Function Participant. When the Servicer, the Trustee, the
Servicer and the Custodian (so long as the Custodian is not the Securities

pursuant to Section 3.20(b)) of each Servicing Function Participant engaged by
it.

            The Securities Administrator shall confirm that the assessments
address the Relevant Servicing Criteria for each party as set forth on Exhibit S

compliance containing such exceptions. Promptly after receipt of each such
report on assessment of compliance, the Depositor shall review each such report
and, if applicable, consult with the Securities Administrator, the Trustee, the
Custodian, the Servicer and any Servicing Function Participant as to the nature
of any material instance of noncompliance with the Relevant Servicing Criteria
by the Securities Administrator, the Trustee, the Custodian, the Servicer or any
Servicing Function Participant engaged by such parties.

            (b) The Securities Administrator, at its own expense, shall cause a

Securities Administrator, not later than March 5 of each year, or if such day is
not a Business Day, the next Business Day (with a 10 calendar day cure period,
but in no event later than March 15), commencing in March 200 , an electronic
report (with a hard copy to follow within 10 calendar days) to the effect that
(i) it has obtained a representation regarding certain matters from the
management of such party, which includes an assertion that such party has
complied with the Relevant Servicing Criteria, and (ii) on the basis of an
examination conducted by such firm in accordance with standards for attestation
engagements issued or adopted by the Public Company Accounting Oversight Board,
it is expressing an opinion as to whether such party's assessment of compliance
with the Relevant Servicing Criteria was fairly stated in all material respects,
or it cannot express an overall opinion regarding such party's assessment of
compliance with the Relevant Servicing Criteria. In the event that an overall
opinion cannot be expressed, such registered public accounting firm shall state
in such report why it was unable to express such an opinion. Such report must be
available for general use and not contain restricted use language. If requested
by the Securities Administrator or the Depositor, such report shall contain or
be accompanied by a consent of such accounting firm to inclusion or
incorporation of such report in the Depositor's Registration Statement on Form
S-3 relating to the Certificates and the Trust's Form 10-K.

            Promptly after receipt of such report from the Securities
Administrator, the Depositor shall review the report and, if applicable, consult
with the Securities Administrator if any such report (i) states that the party's
assessment of compliance was not fairly stated in a material respect or (ii) is
unable to state an overall opinion.

            Promptly after receipt of such report from the Trustee, the
Custodian, the Servicer or any Servicing Function Participant engaged by such
parties, the Securities Administrator shall review the report and shall promptly
notify the Depositor if any such report (i) states that the party's assessment
of compliance was not fairly stated in a material respect or (ii) is unable to
state an overall opinion and the Depositor shall promptly review each such
report and the Depositor and the Securities Administrator shall consult with the
parties to which such report relates.

             (c) The Securities Administrator shall make available any report
