            This Pooling and Servicing Agreement is dated as of [_______] 1, 20
(the "Agreement"), among WELLS FARGO ASSET SECURITIES CORPORATION, as depositor
(the "Depositor"), WELLS FARGO HOME MORTGAGE, INC., as servicer (the
"Servicer"), WELLS FARGO BANK, NATIONAL ASSOCIATION, as securities administrator
(the "Securities Administrator") and [______________________], 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 thirteen
Classes of Certificates, designated as (i) the Class A-1, Class A-1A and Class
A-2 Certificates, (ii) the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5
and Class M-6 Certificates, (iii) the Class B Certificates, (iv) the Class CE
Certificates, (v) the Class P Certificates and (vi) the Class R Certificate.

                                     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 Fund, the Cap Carryover Amounts and the Prepayment
Charges) 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 Regulations Section 1.860G-1(a)(4)(iii), the
"latest possible maturity date" for each of the REMIC 1 Regular Interests. None
of the REMIC 1 Regular Interests will be certificated.

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 Servicer for recordation.

            The Depositor herewith delivers to the Trustee and the Securities
Administrator an executed copy of the Mortgage Loan Purchase Agreement.

            It is agreed and understood by the Depositor and the Trustee that it
is not intended that any mortgage loan be included in the Trust Fund that is a
"High-Cost Home Loan" as defined in either (i) the New Jersey Home Ownership Act
effective November 27, 2003 or (ii) the New Mexico Home Loan Protection Act
effective January 1, 2004.

            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 a 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 and the
Depositor on or prior to the Closing Date an initial certification in the form
attached hereto as Exhibit F-1 hereto, certifying that it has received all
documents required to be delivered to it pursuant to Section 2.01 of this
Agreement, for 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 agrees, for the benefit of the Certificateholders, to
review each Mortgage File within 45 days after the Closing Date (or, with
respect to any document delivered after the Startup Day, within 45 days of
receipt and with respect to any Qualified Substitute Mortgage, within 45 days
after the assignment thereof) and to certify in substantially the form attached
hereto as Exhibit F-2 no later than 30 days after completion of such review
that, as to each Mortgage Loan listed in the Mortgage Loan Schedules (other than
any Mortgage Loan paid in full or any Mortgage Loan specifically identified in
the exception report annexed thereto as not being covered by such
certification), (i) all documents required to be delivered to it pursuant to
Section 2.01 of this Agreement are in its possession, (ii) such documents have
been reviewed by it and have not been mutilated, damaged or torn and relate to
such Mortgage Loan and (iii) based on its examination and only as to the
foregoing, the information set forth in the Mortgage Loan Schedules that
corresponds to items (1), (2), (3), (10) and (22) of the Mortgage Loan Schedules
accurately reflects information set forth in the Mortgage File. It is herein
acknowledged that, in conducting such review, the Custodian is under no duty or
obligation to inspect, review or examine any such documents, instruments,
certificates or other papers to determine that they are genuine, enforceable, or
appropriate for the represented purpose or that they have actually been recorded
or that they are other than what they purport to be on their face.

            Prior to the first anniversary date of this Agreement the Custodian
shall deliver to the Depositor, the Trustee, the Securities Administrator and
the Servicer a final certification in the form annexed hereto as Exhibit F-3
evidencing the completeness of the Mortgage Files, with any applicable
exceptions noted 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 Trustee 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, a 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 which materially adversely affects the value of
such Mortgage Loan, Prepayment Charge 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)). 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 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 released pursuant hereto and the Custodian
shall have no further responsibility with regard to such 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(c).

            It is understood and agreed that the representations and warranties
set forth in Section 2.04 hereof shall survive delivery of the 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.

            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.

            (b) 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.

            (c) 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 Trustee 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, 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 a certification substantially in the
form of Exhibit F-3 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. 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 Mortgage File or Files 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 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.

            (d) 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(c), 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.

            Section 2.04 Representations and Warranties of the Depositor with
respect to the Mortgage Loans.

            The Depositor hereby represents and warrants to the Trustee for the
benefit of the Certificateholders that as of the Closing Date or as of such
other date specifically provided herein:

            (a) The information set forth in the Mortgage Loan Schedules
attached hereto is true and correct, including, without limitation, the
information regarding any Prepayment Charge;

            (b) No payment required under any Mortgage Loan will be 30 days or
more delinquent on the Closing Date. No Mortgage Loan will have been 30 days
delinquent more than once during the 12 months preceding the Closing Date;

            (c) There are no defaults in complying with the terms of the
Mortgages, and all taxes, governmental assessments, insurance premiums,
leasehold payments, water, sewer and municipal charges, which previously became
due and owing have been paid, or an escrow of funds has been established in an
amount sufficient to pay for every such item which remains unpaid and which has
been assessed but is not yet due and payable. Neither the Seller nor the
Depositor has advanced funds, or induced, or solicited directly or indirectly,
the payment of any amount required under the Mortgage Loan, except for interest
accruing from the date of the Mortgage Note or date of disbursement of the
Mortgage Loan proceeds, whichever is later, to the day which precedes by one
month the Due Date of the first installment of principal and interest;

            (d) The terms of the Mortgage Note and Mortgage have not been
impaired, waived, altered or modified in any respect, except by a written
instrument which has been recorded, if necessary, to protect the interests of
the Certificateholders and which has been delivered to the Custodian. The
substance of any such waiver, alteration or modification has been approved by
the issuer of any related primary mortgage insurance policy and the title
insurer, to the extent required by the policy, and its terms are reflected on
the applicable Mortgage Loan Schedule. No Mortgagor has been released, in whole
or in part, except in connection with an assumption agreement approved by the
issuer of any related primary mortgage insurance policy and the title insurer,
to the extent required by the policy, and which assumption agreement is part of
the Mortgage File delivered to the Custodian and the terms of which are
reflected in the applicable Mortgage Loan Schedule;

            (e) The Mortgage Loan is not subject to any right of rescission,
set-off, counterclaim or defense, including without limitation the defense of
usury, nor will the operation of any of the terms of the Mortgage Note or the
Mortgage, or the exercise of any right thereunder, render either the Mortgage
Note or the Mortgage unenforceable, in whole or in part, or subject to any right
of rescission, set-off, counterclaim or defense, including without limitation
the defense of usury, and no such right of rescission, set-off, counterclaim or
defense has been asserted with respect thereto;

            (f) Neither the Mortgage nor the Mortgage Note has been satisfied,
canceled, subordinated or rescinded, in whole or in part, and the Mortgaged
Property has not been released from the lien of the Mortgage, in whole or in
part, nor has any instrument been executed that would effect any such release,
cancellation, subordination or rescission;

            (g) The Mortgage Note and the Mortgage and all other documents
executed in connection with the Mortgage Loan are genuine, and each is the
legal, valid and binding obligation of the maker thereof enforceable in
accordance with its terms. All parties to the Mortgage Note, the Mortgage and
any other related document had legal capacity to enter into the Mortgage Loan
and to execute and deliver the Mortgage Note, the Mortgage and any other related
document, and the Mortgage Note, the Mortgage and any other related document
have been duly and properly executed by such parties. The Seller has reviewed
all of the documents constituting the Mortgage File and has made such inquiries
as it deems necessary to make and confirm the accuracy of the representations
set forth herein;

            (h) All the documents executed in connection with the Mortgage Loan
including, but not limited to, the Mortgage Note and the Mortgage are free of
fraud and any misrepresentation and are signed by the persons they purport to be
signed by, and witnessed or, as appropriate, notarized by the persons whose
signatures appear as witnesses or notaries, and each such document constitutes
the valid and binding legal obligation of the signatories and is enforceable in
accordance with its terms;

            (i) Any and all requirements of any federal, state or local law
including, without limitation, usury, truth-in-lending, real estate settlement
procedures, consumer credit protection, equal credit opportunity, disclosure, or
predatory and abusive lending laws applicable to the Mortgage Loan have been
complied with, and the Seller shall maintain in its possession, evidence of
compliance with all such requirements. The consummation of the transactions
contemplated hereby will not violate any such laws or regulations. All
inspections, licenses and certificates required to be made or issued with
respect to all occupied portions of the Mortgaged Property and, with respect to
the use and occupancy of the same, including, but not limited to, certificates
of occupancy and fire underwriting certificates, have been made or obtained from
the appropriate authorities;

            (j) The Mortgaged Property is located in the state identified in the
applicable Mortgage Loan Schedule and consists of a contiguous parcel of real
property with a detached single family residence erected thereon, or a two- to
four-family dwelling, or an individual condominium unit in a condominium
project, or an individual unit in a planned unit development or a townhouse, or
a manufactured dwelling, and no residence or dwelling is a mobile home. As of
the respective appraisal date for each Mortgaged Property, no portion of the
Mortgaged Property was being used for commercial purposes, except as allowed
under the underwriting guidelines of the Seller. If the Mortgaged Property is a
condominium unit or a planned unit development (other than a de minimus planned
unit development) such condominium or planned unit development meets the
requirements under the underwriting guidelines of the Seller.

            (k) The Mortgage is a valid, subsisting and enforceable first or
second lien on the Mortgaged Property, including all buildings on the Mortgaged
Property and all installations and mechanical, electrical, plumbing, heating and
air conditioning systems located in or annexed to such buildings, and all
additions, alterations and replacements made at any time with respect to the
foregoing. The lien of the Mortgage is subject only to:

            (i) the lien of current real property taxes and assessments not yet
      due and payable;

            (ii) covenants, conditions and restrictions, rights of way,
      easements and other matters of the public record as of the date of
      recording acceptable to mortgage lending institutions generally and
      specifically referred to in the lender's title insurance policy delivered
      to the originator of the Mortgage Loan and (i) referred to or otherwise
      considered in the appraisal made for the originator of the Mortgage Loan
      and (ii) which do not adversely affect the Appraised Value of the
      Mortgaged Property set forth in such appraisal; and

            (iii) other matters to which like properties are commonly subject
      which do not materially interfere with the benefits of the security
      intended to be provided by the mortgage or the use, enjoyment, value or
      marketability of the related Mortgaged Property.

            Any security agreement, chattel mortgage or equivalent document
related to and delivered in connection with the Mortgage Loan establishes and
creates a valid, subsisting and enforceable first or second lien and first or
second priority security interest on the property described therein and the
Depositor has full right to sell and assign the same;

            (l) The Mortgage Loan has been closed and the proceeds of the
Mortgage Loan have been fully disbursed, except for Mortgage Loans with escrow
holdbacks established or created due to seasonal weather conditions, as allowed
under the underwriting guidelines of the Seller, and there is no requirement for
future advances thereunder. All costs, fees and expenses incurred in making or
closing the Mortgage Loan and the recording of the Mortgage were paid, and the
Mortgagor is not entitled to any refund of any amounts paid or due under the
Mortgage Note or Mortgage;

            (m) Any future advances made prior to the Cut-off Date, have been
consolidated with the outstanding principal amount secured by the Mortgage, and
the secured principal amount, as consolidated, bears a single interest rate and
single repayment term reflected on the applicable Mortgage Loan Schedule. The
lien of the Mortgage securing the consolidated principal amount is expressly
insured as having first or second lien priority by a title insurance policy, an
endorsement to the policy insuring the mortgagee's consolidated interest or by
other title evidence acceptable to Fannie Mae or Freddie Mac; the consolidated
principal amount does not exceed the original principal amount of the Mortgage
Loan; the Seller shall not make future advances after the Cut-off Date;

            (n) The Depositor is the sole owner of record and holder of the
Mortgage Loan and the related Mortgage Note and the Mortgage are not assigned or
pledged, and the Depositor has good and marketable title thereto and has full
right and authority to transfer and sell the Mortgage Loan. The Depositor is
transferring the Mortgage Loan free and clear of any and all encumbrances,
liens, pledges, equities, participation interests, claims, charges or security
interests of any nature encumbering such Mortgage Loan;

            (o) The Mortgage Loan was originated by a savings and loan
association, a savings bank, a commercial bank, a credit union, an insurance
company, or similar institution that is supervised and examined by a federal or
state authority, or by a mortgagee approved by the Secretary of Housing and
Urban Development pursuant to Sections 203 and 211 of the National Housing Act.
All parties which have had any interest in the Mortgage Loan, whether as
mortgagee, assignee, pledgee or otherwise, are (or, during the period in which
they held and disposed of such interest, were) (1) in compliance with any and
all applicable licensing requirements of the laws of the state wherein the
Mortgaged Property is located, and (2) organized under the laws of such state,
or (3) qualified to do business in such state, or (4) federal savings and loan
associations or national banks having principal offices in such state, or (5)
not doing business in such state;

            (p) The Mortgage Loan is covered by an ALTA lender's title insurance
policy (or in the case of any Mortgage Loan secured by a Mortgaged Property
located in a jurisdiction where such policies are generally not available, an
opinion of counsel of the type customarily rendered in such jurisdiction in lieu
of title insurance and acceptable to Fannie Mae or Freddie Mac) or other
generally acceptable form of policy of insurance acceptable to Fannie Mae or
Freddie Mac, issued by a title insurer acceptable to Fannie Mae or Freddie Mac
and qualified to do business in the jurisdiction where the Mortgaged Property is
located, insuring the Company, its successors and assigns, as to the first or
second priority lien of the Mortgage in the original principal amount of the
Mortgage Loan, subject only to the exceptions contained in clauses (1), (2) and
(3) of Paragraph (k) above, and against any loss by reason of the invalidity or
unenforceability of the lien resulting from the provisions of the Mortgage
providing for adjustment to the Mortgage Interest Rate and Monthly Payment. The
Depositor is the sole insured of such lender's title insurance policy, and such
lender's title insurance policy is in full force and effect and will be in force
and effect upon the consummation of the transactions contemplated by this
Agreement. No claims have been made under such lender's title insurance policy,
and no prior holder of the Mortgage, including the Depositor, has done, by act
or omission, anything which would impair the coverage of such lender's title
insurance policy;

            (q) There is no default, breach, violation or event of acceleration
existing under the Mortgage or the Mortgage Note or related documents 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, and neither the Depositor nor its predecessors have waived any
default, breach, violation or event of acceleration;

            (r) There are no mechanics' or similar liens or claims which have
been filed for work, labor or material (and no rights are outstanding that under
the law could give rise to such liens) affecting the related Mortgaged Property
which are or may be liens prior to, or equal or coordinate with, the lien of the
related Mortgage which are not insured against by the title insurance policy
referenced in Paragraph (p) above;

            (s) All improvements which were considered in determining the
Appraised Value of the Mortgaged Property lay wholly within the boundaries and
building restriction lines of the Mortgaged Property and except as insured
against by the title insurance policy referenced in Paragraph (p) above, no
improvements on adjoining properties encroach upon the Mortgaged Property. No
improvement located on or being part of the Mortgaged Property is in violation
of any applicable zoning law or regulation;

            (t) Principal payments commenced no more than 60 days after the
funds were disbursed to the Mortgagor in connection with the Mortgage Loan. Each
Mortgage Loan is payable each month in equal monthly installments of principal
and interest, with interest calculated and payable in arrears, sufficient to
amortize the Mortgage Loan fully by the stated maturity date set for in the
Mortgage Note over an original term to maturity of not more than 30 years. No
Mortgage Loan contains terms or provisions which would result in negative
amortization;

            (u) The Mortgage Loans have an original term to maturity of not more
than 30 years, with interest payable in arrears each month. As to each
Adjustable Rate Mortgage Loan on each applicable adjustment date, the Mortgage
Rate will be adjusted to equal the sum of the Index plus the applicable gross
margin, rounded up or down to the nearest multiple of 0.125% indicated by the
Mortgage Note; provided that the Mortgage Interest Rate will not increase or
decrease by more than the Periodic Cap on any Adjustment Date, and will in no
event exceed the Maximum Mortgage Interest Rate or be lower than the Minimum
Mortgage Interest Rate listed on the related Mortgage Loan Schedule for such
Mortgage Loan. Each Mortgage Note requires a monthly payment which is
sufficient, during the period prior to the first adjustment to the Mortgage
Rate, to fully amortize the outstanding principal balance as of the first day of
such period over the then remaining term of such Mortgage Note and to pay
interest at the related Mortgage Rate. As to each Adjustable Rate Mortgage Loan,
if the related Mortgage Interest Rate changes on an Adjustment Date, the then
outstanding Principal Balance will be reamortized over the remaining life of
such Mortgage Loan. No Mortgage Loan contains terms or provisions which would
result in negative amortization;

            (v) The Mortgage and related Mortgage Note contain 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 provided thereby, including, (i) in the case of a
Mortgage designated as a deed of trust, by trustee's sale, and (ii) otherwise by
judicial foreclosure and upon the exercise of such rights and remedies under the
law, the holder of the Mortgage and Mortgage Note will be able to deliver good
and merchantable title to the Mortgaged Property. There is no homestead or other
exemption available to a Mortgagor which would interfere with the right to sell
the Mortgaged Property at a trustee's sale or the right to foreclose the
Mortgage;

            (w) As of the date of origination, the Mortgaged Property was
lawfully occupied under applicable law;

            (x) The Mortgage Note is not and has not been secured by any
collateral, pledged account or other security except the lien of the
corresponding Mortgage and the security interest of any applicable security
agreement or chattel mortgage referred to in (k) above;

            (y) In the event the Mortgage constitutes a deed of trust, a
trustee, duly qualified under applicable law to serve as such, has been properly
designated and currently so serves and is named in the Mortgage, and no fees or
expenses are or will become payable by the Mortgagee to the trustee under the
deed of trust, except in connection with a trustee's sale after default by the
Mortgagor;

            (z) The Assignment of Mortgage upon the insertion of the name of the
assignee and recording information is in recordable form and is acceptable for
recording under the laws of the jurisdiction in which the Mortgaged Property is
located;

            (aa) The Mortgaged Property is undamaged by waste, fire, earthquake
or earth movement, windstorm, flood, tornado or other casualty so as to affect
adversely the value of the Mortgaged Property as security for the Mortgage Loan
or the use for which the premises were intended;

            (bb) The origination and collection practices used with respect to
the Mortgage Loan have been in accordance with the Servicing Standard, and have
been in all material respects legal and proper. With respect to escrow deposits
and escrow payments, all such payments are in the possession of the Depositor
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. All escrow payments have
been collected in full compliance with state and federal law. No escrow deposits
or escrow payments or other charges or payments due the Depositor have been
capitalized under the Mortgage Note;

            (cc) There is no proceeding pending or to the best of the
Depositor's knowledge threatened for the total or partial condemnation of the
related Mortgaged Property;

            (dd) The Related Documents contains an appraisal of the related
Mortgaged Property by an appraiser who is licensed in the state where the
Mortgaged Property is located, and who had no interest, direct or indirect, in
the Mortgaged Property or in any loan made on the security thereof; and whose
compensation is not affected by the approval or disapproval of the Mortgage
Loan, and the appraisal and the appraiser both satisfy the applicable
requirements of Title XI of the Financial Institution Reform, Recovery, and
Enforcement Act of 1989 and the regulations promulgated thereunder, all as in
effect on the date the Mortgage Loan was originated;

            (ee) 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 and
such other hazards as are customary in the area where the Mortgaged Property is
located pursuant to insurance policies conforming to the requirements of this
Agreement, 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 the improvements on the
Mortgaged Property are 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 and (C) the maximum amount of insurance which was available
under the Flood Disaster Protection Act of 1973, as amended. All individual
insurance policies contain a standard mortgagee clause naming the Company and
its successors and assigns as mortgagee, and all premiums thereon have been
paid. The Mortgage obligates the Mortgagor thereunder to maintain a hazard
insurance policy at the Mortgagor's cost and expense, and on the Mortgagor's
failure to do so, authorizes the holder of the Mortgage to obtain and maintain
such insurance at such Mortgagor's cost and expense, and to seek reimbursement
therefor from the Mortgagor. The hazard insurance policy is the valid and
binding obligation of the insurer, is in full force and effect, and will be in
full force and effect and inure to the benefit of the Trustee on behalf of the

      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 contemplated hereby have
      been duly and validly authorized; and all requisite corporate action has
      been taken by the Servicer to make this Agreement valid and binding upon
      the Servicer in accordance with its terms;

      Agreement are in the ordinary course of business of the Servicer and will
      not result in the breach of any term or provision of the articles of
      incorporation or by-laws of the Servicer or result in the breach of any
      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

      residential mortgage loans for Fannie Mae or Freddie Mac, with the
      facilities, procedures, and experienced personnel necessary for the sound
      servicing of mortgage loans of the same type as the Mortgage Loans. The
      Servicer is a HUD approved mortgagee pursuant to Section 203 of the
      National Housing Act and is in good standing to sell mortgage loans to and
      service mortgage loans for Fannie Mae or Freddie Mac, and no event has
      occurred, including but not limited to a change in insurance coverage,

      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,

      cause to believe, that it cannot perform each and every covenant contained
      in this Agreement;

            (vi) There is no action, suit, proceeding or investigation pending
      or, to its knowledge, threatened against the Servicer that, either
      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;

            (vii) No consent, approval or order of any court or governmental
      agency or body is required for the execution, delivery and performance by
      the Servicer of or compliance by the Servicer with this Agreement or the

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

            (viii) No information in this Agreement provided by the Servicer nor
      any information, certificate of an officer, statement furnished in writing
      or report delivered to the Trustee or the Securities Administrator by the
      Servicer in connection with the transactions contemplated hereby contains
      or will contain any untrue statement of a material fact or omits or will
      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.

            (ix) The Servicer has fully furnished, and shall continue to fully
      furnish for so long as it is servicing the Mortgage Loans hereunder, in
      accordance with the Fair Credit Reporting Act and its implementing
      regulations, accurate and complete information on the Mortgagor credit
      files to Equifax, Experian and Trans Union Credit Information Company on a
      monthly basis.

            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

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 Charge or the interests therein of the Certificateholders, the party
discovering such breach shall give prompt written notice (but in no event later

      agreement or other agreement or instrument to which the Depositor is a

                          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 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 Standard").

            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, imminent) 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
constituting part of the Trust Fund as a REMIC or (iii) cause any such REMIC 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 duties hereunder.

            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.

            The Servicer shall give prompt notice to the Trustee of any action,
of which the Servicer has actual knowledge, to (i) assert a claim against the
Trust Fund or (ii) assert jurisdiction over the Trust Fund.

            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 Standard
set froth in this Agreement 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 Mortgage, 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 prudent mortgage servicers would
exercise or use under the circumstances in the conduct of their own affairs and
consistent with Applicable Regulations and the Servicing Standards, including,
without limitation, advancing funds for the payment of taxes and insurance
premiums.

            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, 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.

            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(iv).

            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, clean-up 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.

            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 Collection
Accounts. Each Collection Account shall be an Eligible Account.

            The Servicer shall deposit in the Collection Account on a daily
basis within three Business Days of receipt, and retain therein, the following
payments and collections received or made by it after the 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 Liquidation Proceeds;

            (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 Charges collected by the Servicer in connection
      with the voluntary Principal Prepayment in full of any Mortgage Loan; 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 3.25, 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 charges that are not
Prepayment Charges, assumption fees and other similar fees need not be deposited
by the Servicer in the Collection Account. Amounts deposited in the Collection
Account in error may be withdrawn by the Servicer at any time.

            (b) On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Certificateholders. On behalf of
the Trust Fund, the Servicer shall deliver to the Trustee in immediately
available funds for deposit in the Distribution Account by the close of business
New York 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, and (ii)
the amount of all Prepayment Charges 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
Charges received after the related Prepayment Period). Amounts in the
Distribution Account shall be deemed to be held on behalf of the related REMICs
and the Grantor Trust in accordance with the REMIC distributions set forth in
Section 4.08. The Securities Administrator shall be entitled to cause the
Trustee to withdraw from the Distribution Account any amounts owing to it
pursuant to Section 8.05 and Section 9.01(c) prior to the distribution of any
amounts on deposit to the Certificateholders; provided, however, in the case of
amounts owing to it other than the Securities Administrator Fee, the Securities
Administrator shall provide the Depositor and the Servicer with a written
account of such amounts five Business Days prior to withdrawing such funds.

            (c) Funds in the Collection Account and the Distribution Account may
be invested in Eligible Investments in accordance with the provisions set forth
in Section 3.25. The Servicer shall give notice to the Trustee and the
Securities Administrator of the location of the Collection Account maintained by
it when established and prior to any change thereof. The Trustee shall give
notice to the Servicer, the Securities Administrator 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 Trustee for
deposit in the Distribution Account any amount not required to be deposited
therein, it may at any time request that the Trustee 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 Trustee from time to time for deposit, and the Trustee
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 amounts required to be deposited in the Distribution
      Account by the Servicer or the Depositor pursuant to Sections 2.03, 3.04,
      3.13, 3.15, 3.16, 3.23, 3.24, 4.07 or 10.01; and

            (iv) 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 Trustee shall 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 3.25(b) in
connection with losses realized on Eligible Investments with respect to funds
held in the Distribution Account.

            (f) Any Prepayment Charges, Originator Prepayment Charge Payment
Amounts and Servicer Prepayment Charge 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 Trustee for the
benefit of the Class P Certificateholders.

            (g) (i) The Trustee shall establish and maintain the Reserve
Account, held in trust for the benefit of the Holders of the Offered
Certificates. The Trustee 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 Trustee shall withdraw from the Reserve Account any Yield
Maintenance Agreement Payment and apply it in the following order of priority:

                  (A) to the Offered Certificates, any remaining unpaid Cap
            Carryover Amounts for such Classes for such Distribution Date (after
            distributions pursuant to Section 4.02(b)(xxv) hereof), in each case
            only up to the Cap Amount for the related Class, distributed in the
            following order of priority:

                        (1) concurrently, to the Class A Certificates, pro rata,
                  based on the Cap Amount for each such Class; and

                        (2) sequentially, to the Class M-1, Class M-2, Class
                  M-3, Class M-4, Class M-5 and Class M-6 Certificates, in that
                  order; and

                  (B) to the Offered Certificates, any remaining unpaid Cap
            Carryover Amounts for such Classes for such Distribution Date (after
            distributions pursuant to Section 4.02(b)(xxv) hereof and clause (A)
            above) distributed in the following order of priority:

                        (1) concurrently, to the Class A Certificates, pro rata,
                  based on the related unpaid Cap Carryover Amount for each such
                  Class; and

                        (2) sequentially, to the Class M-1, Class M-2, Class
                  M-3, Class M-4, Class M-5 and Class M-6 Certificates, in that
                  order; and

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

            (ii) 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 2 to the Reserve Account shall be treated as
      distributions by the Trustee to the Class CE Certificateholder.

            (iii) Any Cap Carryover Amounts paid by the Trustee pursuant to this
      Section 3.04(g) to the Offered 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 Offered
      Certificates. In addition, the Securities Administrator shall account for
      the Offered 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 Offered Certificates.

            (iv) For federal tax return and information reporting, the right of
      the Holders of the Offered Certificates to receive payments under the
      Yield Maintenance Agreement in respect of any 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 Trustee 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) to reimburse itself for (a) any unreimbursed Advances to the
      extent of amounts received which represent Late Collections (net of the
      related Servicing Fees) of Monthly Payments, Liquidation Proceeds and
      Insurance Proceeds on Mortgage Loans with respect to which such Advances
      were made in accordance with the provisions of Section 4.07; (b) any
      unreimbursed Advances with respect to the final liquidation of a Mortgage
      Loan that are Nonrecoverable Advances, but only to the extent that Late
      Collections, Liquidation Proceeds and Insurance Proceeds received with
      respect to such Mortgage Loan are insufficient to reimburse the Servicer
      for such unreimbursed Advances; or (c) subject to Section 4.07(b), any
      unreimbursed Advances to the extent of funds held in the Collection
      Account for future distribution that were not included in Available Funds
      for the preceding Distribution Date;

            (iii) to reimburse itself for (a) any unpaid Servicing Fees, (b) any
      unreimbursed Servicing Advances with respect to each Mortgage Loan, but
      only to the extent of any Late Collections, Liquidation Proceeds,
      Insurance Proceeds and condemnation proceeds received with respect to such
      Mortgage Loan, and (c) any Servicing Advances with respect to the final
      liquidation of a Mortgage Loan that are Nonrecoverable Advances, but only
      to the extent that Late Collections, Liquidation Proceeds and Insurance
      Proceeds received with respect to such Mortgage Loan are insufficient to
      reimburse the Servicer for Servicing Advances;

            (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), (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(a)(ii) and (c) any Prepayment Interest Excess;

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

            (vii) 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 on a
daily basis within three Business Days of receipt, in no event more than one
Business Day after deposit of such funds in the clearing account, 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 that provides for Escrow
Payments, 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 Mortgage
Note or Applicable Regulations. To the extent that a Mortgage Loan does not
provide for Escrow Payments, 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) The Servicer shall maintain coverage under primary mortgage
insurance policies for all Mortgage Loans with Loan-to-Value Ratios at
origination of 80% or greater, 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. The Seller shall be required, pursuant to the Mortgage
Loan Purchase Agreement, to make all premium payments with respect to such
primary mortgage insurance policies.

            Section 3.09 Transfer of Accounts.

            The Servicer may transfer the Collection Account and the Escrow
Account to a different depository institution from time to time. Upon such
transfer, the Servicer shall deliver to the Trustee, the Securities
Administrator and the Depositor, 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,
(y) public liability insurance and, (z) to the extent required and available
under the National Flood Insurance Act of 1968, 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:III 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:III 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 Trustee 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 Trustee, the Servicer shall cause to be delivered to the
Trustee 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 at least
equal to the corresponding amounts required by Fannie Mae in the Fannie Mae MBS
Selling and Servicing Guide or by Freddie Mac in the Freddie Mac Servicer's
Guide. Upon request of the Trustee, the Servicer shall cause to be delivered to
the requesting party 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 thirty days' prior written notice
to the Trustee.

            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 or its nominee, on behalf of the
Certificateholders, or in the event the Trustee or its nominee 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 unless the Servicer has
received a grant of extension from the Internal Revenue Service of the
above-mentioned grace period such 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 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
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 account
separately for each REO Property with respect to all funds collected and
received in connection with the operation of such REO Property.

            The Servicer shall deposit or cause to be deposited, on a daily
basis, within three Business Days of receipt, in the Collection Account, all
revenues received with respect to each REO Property and shall withdraw therefrom
funds necessary for the proper operation, management and maintenance of the
related 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.
Such operating statement shall be accompanied by such other information as 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, Servicing Fees and 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, Servicing Fees
and Advances from proceeds received in connection with such REO Disposition. The
proceeds from the REO Disposition, net of any payment to the Servicer as
provided above, shall be deposited in the Collection Account for transfer to the
Distribution Account on the succeeding Servicer Remittance Date in accordance
with Section 3.04(a)(vi).

            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. 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 Notification of Adjustments.

            On each Adjustment Date, the Servicer shall make Mortgage Interest
Rate adjustments for each Adjustable-Rate Mortgage Loan in compliance with the
requirements of the related Mortgage and Mortgage Note and Applicable
Regulations. The Servicer shall execute and deliver the notices required by each
Mortgage and Mortgage Note and Applicable Regulations regarding Mortgage
Interest Rate adjustments. Upon the discovery by the Servicer or the Trustee
that the Servicer has failed to adjust or has incorrectly adjusted a Mortgage
Interest Rate or a Monthly Payment pursuant to the terms of the related Mortgage
Note and Mortgage, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any interest loss caused
thereby without reimbursement therefor; provided, however, the Servicer shall be
held harmless with respect to any Mortgage Interest Rate adjustments made by any
servicer prior to the Servicer.

            Section 3.16 Optional Purchases of Mortgage Loans by the Depositor.

            The Depositor shall have a limited option to repurchase any
defaulted Mortgage Loan or REO Mortgage Loan during the following time periods:
(i) beginning on the first day of the second month following the month in which
the Servicer has initiated foreclosure proceedings with respect to such a
defaulted Mortgage 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 Mortgage Loan, 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 defaulted Mortgage Loan or REO
Mortgage Loan, 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 defaulted Mortgage Loan or REO Mortgage Loan.

            The Depositor shall purchase such REO Mortgage Loan at a price equal
to the Purchase Price. Any such purchase of an REO Mortgage Loan pursuant to
this Section 3.16 shall be accomplished by delivery to the Trustee for deposit
in the Distribution Account of the amount of the Purchase Price. The Trustee (or
the Custodian, as the case may be) shall immediately effectuate the conveyance
of such REO Mortgage Loan to the Depositor to the extent necessary, including
the prompt delivery of all documentation to the Depositor.

            Section 3.17 Trustee to Cooperate; Release of Files.

            (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such 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 deliver to the
Trustee (or the Custodian, as the case may be) an executed copy of a completed
"Request for Release" in the form of Exhibit E. Upon receipt of such Request for
Release of Documents, the Trustee (or the Custodian, as the case may be) shall
promptly release the related Mortgage File, in trust, to (i) the Servicer, or
(ii) such other party identified in the related Request for Release. No expense
incurred in connection with such instrument of satisfaction or assignment, as
the case may be, shall be chargeable to the Collection Account.

            (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any insurance policy relating
to a Mortgage Loan, the Trustee shall (except in the case of the payment or
liquidation pursuant to which the related Mortgage File is released to an escrow
agent or an employee, agent or attorney of the Trustee), upon written request of
the Servicer and delivery to the Trustee (or the Custodian, as the case may be),
an executed copy of a "Request for Release" in the form of Exhibit E signed by a
Servicing Officer, release the related Mortgage File to the Servicer and shall
execute such documents as shall be necessary to the prosecution of any such
proceedings, including, without limitation, an assignment without recourse of
the related Mortgage to the Servicer. Such receipt shall obligate the Servicer
to return the Mortgage File to the Trustee (or the Custodian, as the case may
be)when the need therefor by the Servicer no longer exists unless the Mortgage
Loan shall be liquidated, in which case, upon receipt of a Request for Release
evidencing such liquidation, the receipt shall be released by the Trustee (or
the Custodian, as the case may be) to the Servicer.

            (c) 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 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 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 charges that are not Prepayment Charges, or any other service-related
fees and similar items, to the extent collected from Mortgagors.

            Section 3.19 Annual Statement as to Compliance.

            (a) The Servicer, at its own expense, will deliver to the Securities
Administrator, not later than February 28 following the end of each calendar
year, commencing in February 20 , a Servicing Officer's certificate stating, as
to each signer thereof, that (i) a review of the activities of the Servicer
during such preceding calendar year and of performance under this Agreement has
been made under such officers' supervision, and (ii) to the best of such
officer's knowledge, based on such review, the Servicer has fulfilled all its
obligations under this Agreement for such year, or, if there has been a default
in the fulfillment of all such obligations, specifying each such default known
to such officers and the nature and status thereof including the steps being
taken by the Servicer to remedy such default. The Securities Administrator shall
forward such certificate to the Depositor and the Trustee immediately upon
receipt.

            (b) Delivery of such reports, information and documents to the
Securities Administrator is for informational purposes only and the Trustee's,
Securities Administrator's and Depositor's receipt of such shall not constitute
constructive notice of any information contained therein or determinable, from
information contained therein, including the Servicer's compliance with any of
its covenants hereunder (as to which the Trustee, the Securities Administrator
and the Depositor are entitled to rely exclusively on Officers' Certificates).

            Section 3.20 Annual Independent Certified Public Accountants'
Reports.

            (a) Not later than February 28 following the end of each calendar
year commencing with 20 , the Servicer, at its expense, shall cause a nationally
recognized firm of independent certified public accountants to furnish to the
Securities Administrator, a report stating that (i) it has obtained a letter of
representation regarding certain matters from the management of the Servicer
which includes an assertion that the Servicer has complied with certain minimum
residential mortgage loan servicing standards, identified in either the Uniform
Single Attestation Program for Mortgage Bankers established by the Mortgage
Bankers Association of America or the Audit Program for Mortgages serviced by
Freddie Mac, with respect to the servicing of residential mortgage loans during
the most recently completed calendar year and (ii) on the basis of an
examination conducted by such firm in accordance with standards established by
the American Institute of Certified Public Accountants, such representation is
fairly stated in all material respects, subject to such exceptions and other
qualifications that may be appropriate. The Securities Administrator shall
forward a copy of such report to the Depositor, the Trustee and each Rating
Agency immediately upon receipt. Copies of such statement shall be provided by
the Trustee to any Certificateholder upon request, provided that such statement
is delivered by the Servicer to the Trustee.

            (b) Delivery of such reports, information and documents to the
Trustee and the Securities Administrator is for informational purposes only and
their receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Servicer's compliance with any of its covenants hereunder
(as to which the Trustee and the Securities Administrator are entitled to rely
exclusively on Officers' Certificates).

            Section 3.21 Access to Certain Documentation and Information
Regarding the Mortgage Loans.

            The Servicer shall provide to the Trustee, the Securities
Administrator, Certificateholders that are federally insured savings and loan
associations, the Office of Thrift Supervision, the FDIC and the supervisory
agents and examiners of each of the foregoing (which, in the case of supervisory
agents and examiners, may be required by applicable state and federal
regulations) access to the available documentation regarding the Mortgage Loans,
such access being afforded without charge but only upon reasonable advance
request and during normal business hours at the offices of the Servicer
designated by it.

            Section 3.22 Duties of Credit Risk Manager.

            For and on behalf of the Depositor, 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 3.23 Obligations of the Servicer in Respect of Compensating
Interest.

            Not later than the close of business on each Servicer Remittance
Date, the Servicer shall deliver to the Trustee for deposit in the Distribution
Account an amount ("Compensating Interest") equal to the lesser of (A) the
aggregate of the Prepayment Interest Shortfalls on the Mortgage Loans for the
related Distribution Date resulting from Principal Prepayments on the Mortgage
Loans during the related Prepayment Period and (B) its aggregate Servicing Fee
received in the related Collection Period. The Servicer shall apply Compensating
Interest to offset any Prepayment Interest Shortfalls on the Mortgage Loans. The
Servicer shall not have the right to reimbursement for any amounts remitted to
the Trustee in respect of Compensating Interest. Such amounts so remitted shall
be included in the Available Funds and distributed therewith on the next
Distribution Date.

            Section 3.24 Obligations of the Servicer in Respect of Mortgage
Interest Rates and Monthly Payments.

            In the event that a shortfall in any collection on or liability with
respect to any Mortgage Loan results from or is attributable to adjustments to
Mortgage Interest Rates, Monthly Payments or Principal Balances that were made
by the Servicer in a manner not consistent with the terms of the related
Mortgage Note and this Agreement, the Servicer, upon discovery or receipt of
notice thereof, immediately shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any such shortfall and
shall indemnify and hold harmless the Trust Fund, the Trustee, the Securities
Administrator, the Depositor and any successor servicer in respect of any such
liability. Such indemnities shall survive the termination or discharge of this
Agreement. Notwithstanding the foregoing, this Section 3.24 shall not limit the
ability of the Servicer to seek recovery of any such amounts from the related
Mortgagor under the terms of the related Mortgage Note, as permitted by law.

            Section 3.25 Investment of Funds in the Collection Account and the
Distribution Account.

            (a) The Servicer may direct any depository institution maintaining
the Collection Account and the Securities Administrator may direct any
depository institution maintaining the Distribution Account (for purposes of
this Section 3.25, each an "Investment Account"), to invest the funds in such
Investment Account in one or more Eligible Investments bearing interest or sold
at a discount, and maturing, unless payable on demand, (i) no later than the
Business Day immediately preceding the date on which such funds are required to
be withdrawn from such account pursuant to this Agreement, if a Person other
than the Trustee is the obligor thereon, and (ii) no later than the date on
which such funds are required to be withdrawn from such account pursuant to this
Agreement, if the Trustee is the obligor thereon. All such Eligible Investments
shall be held to maturity, unless payable on demand. Any investment of funds in
an Investment Account shall be made in the name of the Securities Administrator
or the Servicer, as applicable (in its capacity as such) or in the name of a
nominee of the Trustee. The Servicer or the Securities Administrator shall be
entitled to sole possession (except with respect to investment direction of
funds held in the Collection Account) over each such investment and the income
thereon, and any certificate or other instrument evidencing any such investment
shall be delivered directly to the Securities Administrator or its agent,
together with any document of transfer necessary to transfer title to such
investment to the Securities Administrator or its nominee. In the event amounts
on deposit in an Investment Account are at any time invested in an Eligible
Investment payable on demand, the Trustee shall at the direction of the Servicer
or the Securities Administrator:

                  (x)   consistent with any notice required to be given
                        thereunder, demand that payment thereon be made on the
                        last day such Eligible Investment may otherwise mature
                        hereunder in an amount equal to the lesser of (1) all
                        amounts then payable thereunder and (2) the amount
                        required to be withdrawn on such date; and

                  (y)   demand payment of all amounts due thereunder promptly
                        upon determination by a Responsible Officer of the
                        Trustee that such Eligible Investment would not
                        constitute an Eligible Investment in respect of funds
                        thereafter on deposit in the Investment Account.

            (b) All income and gain realized from the investment of funds in the
Collection Account shall be for the benefit of the Servicer. The Servicer shall
deposit in the Collection Account the amount of any loss incurred in respect of
any such Eligible Investment made with funds in such account immediately upon
realization of such loss. All income and gain realized from the investment of
funds in the Distribution Account shall be for the benefit of the Securities
Administrator. The Securities Administrator shall remit to the Trustee for
deposit in the Distribution Account the amount of any loss incurred on Eligible
Investments in the Distribution Account.

            (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Eligible Investment, or
if a default occurs in any other performance required under any Eligible
Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v),
upon the request of the Holders of Certificates representing more than 50% of
the Voting Interests allocated to any Class of Certificates, shall take such
action as may be appropriate to enforce such payment or performance, including
the institution and prosecution of appropriate proceedings.

            Section 3.26 Liability of Servicer; Indemnification.

            (a) Subject to clause (b) below and Section 6.03, the Servicer
(except the shall if it is required to succeed the Servicer hereunder)
indemnifies and holds the Trustee, the Securities Administrator, the Depositor
(and their respective officers, directors and affiliates) and the Trust Fund
harmless against any and all claims, losses, penalties, fines, forfeitures,
reasonable legal fees and related costs, judgments, and any other costs, fees
and expenses that the Trustee, the Securities Administrator, the Depositor and
the Trust Fund may sustain in any way related to the failure of the Servicer to
perform its duties and service the Mortgage Loans in compliance with the
Servicing Standard. The Servicer shall immediately notify the Trustee, the
Securities Administrator and the Depositor if a claim is made that may result in
such claims, losses, penalties, fines, forfeitures, legal fees or related costs,
judgments, or any other costs, fees and expenses, and the Servicer shall assume
(with the consent of the Securities Administrator) the defense of any such claim
and pay all expenses in connection therewith, including reasonable counsel fees,
and promptly pay, discharge and satisfy any judgment or decree which may be
entered against the Servicer, the Trustee, the Depositor and/or the Trust Fund
in respect of such claim. The provisions of this Section 3.26 shall survive the
termination of this Agreement and the payment of the outstanding Certificates.

            (b) None of the Depositor, the Servicer, or any of the directors,
officers, employees or agents of the Depositor or the Servicer shall be under
any liability to the Trust Fund or the Certificateholders for any action taken,
or for refraining from the taking of any action, in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor or the Servicer or any such Person against any
breach of warranties or representations made by such party herein, or against
any specific liability imposed on the Servicer for a breach of the Servicing
Standard and/or this Agreement, or against any liability which would otherwise
be imposed by reason of its respective willful misfeasance, bad faith, fraud or
negligence in the performance of its duties or by reasons of negligent disregard
of its respective obligations or duties hereunder.

            The Depositor, the Servicer and any director, officer, employee or
agent of the Depositor or the Servicer, may rely in good faith on any document
of any kind which, prima facie, is properly executed and submitted by any
appropriate Person with respect to any matters arising hereunder. The Depositor,
the Servicer and any director, officer, employee or agent of the Depositor or
the Servicer shall be indemnified and held harmless by the Trust against any
loss, liability or expense incurred in connection with any legal action relating
to this Agreement or the Certificates, other than any loss, liability or expense
incurred in connection with any legal action incurred by reason of its
respective misfeasance, bad faith, fraud or negligence, a breach of a
representation or warranty made by such party hereunder or (in the case of the
Servicer) a breach of the Servicing Standard in the performance of its
respective duties or by reason of negligent disregard of its respective
obligations or duties hereunder. Neither the Depositor nor the Servicer shall be
under any obligation to appear in, prosecute or defend any legal action unless
such action is related to its respective duties under this Agreement and in its
opinion does not expose it to any expense or liability; provided, however, that
the Depositor or the Servicer may in their discretion undertake any action
related to their obligations hereunder which they may deem necessary or
desirable with respect to this Agreement and the rights and duties of the
parties hereto and the interests of the Certificateholders hereunder. The
Servicer's right to indemnity or reimbursement pursuant to this Section shall
survive any resignation or termination of the Servicer pursuant to Section 6.04
or 7.01 with respect to any losses, expenses, costs or liabilities arising prior
to such resignation or termination (or arising from events that occurred prior
to such resignation or termination).

            Section 3.27 Reports of Foreclosure and Abandonment of Mortgaged
Properties.

            On or before April 30 of each year beginning in 20 , the Servicer
shall file the reports of foreclosure and abandonment of any Mortgaged Property
required by Section 6050J of the Code with the Internal Revenue Service and
provide an Officer's Certificate to the Trustee certifying its compliance with
this Section 3.27. The reports from the Servicer shall be in form and substance
sufficient to meet the reporting requirements imposed by such Section 6050J.

            Section 3.28 Protection of Assets.

            (a) Except for transactions and activities entered into in
connection with the securitization that is the subject of this Agreement, the
Trust is not authorized and has no power to:

            (1) borrow money or issue debt;

            (2) merge with another entity, reorganize, liquidate or sell assets;
      or

            (3) engage in any business or activities.

            (b) Each party to this Agreement agrees that it will not file an
involuntary bankruptcy petition against the Trustee or the Trust Fund or
initiate any other form of insolvency proceeding until after the Certificates
have been paid.

            Section 3.29 Limitation of Liability of the Credit Risk Manager.

            Neither the Credit Risk Manager, nor any of the directors, officers,
employees or agents of the Credit Risk Manager, shall be under any liability to
the Depositor, the Securities Administrator, the Servicer, the Trustee or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, in reliance upon information
provided by the Servicer under the Credit Risk Management Agreement or for
errors in judgment; provided, however, that this provision shall not protect the
Credit Risk Manager or any such person against liability that would otherwise be
imposed by reason of willful malfeasance, bad faith or negligence in its
performance of its duties or by reason of reckless disregard for its obligations
and duties under this Agreement or the applicable Credit Risk Management
Agreement. The Credit Risk Manager and any director, officer, employee or agent
of the Credit Risk Manager may rely in good faith on any document of any kind
prima facie properly executed and submitted by any Person respecting any matters
arising hereunder, and may rely in good faith upon the accuracy of information
furnished by the Servicer pursuant to the applicable Credit Risk Management
Agreement in the performance of its duties thereunder and hereunder.

            Section 3.30 No Personal Solicitation.

            From and after the Closing Date, the Servicer agrees that it will
not take any action or permit or cause any action to be taken by any of its
agents and Affiliates, or by any independent contractors or independent mortgage
brokerage companies on the Servicer's behalf, to personally, by telephone, mail
or electronic mail, solicit the Mortgagor under any Mortgage Loan for the
purpose of refinancing such Mortgage Loan; provided, that the Servicer may
solicit any Mortgagor for whom the Servicer has received a request for
verification of mortgage, a request for demand for payoff, a mortgagor initiated
written or verbal communication indicating a desire to prepay the related
Mortgage Loan, or the mortgagor initiates a title search; provided further, it
is understood and agreed that promotions undertaken by the Servicer or any of
its Affiliates which (i) concern optional insurance products or other additional
products or (ii) are directed to the general public at large, including, without
limitation, mass mailings based on commercially acquired mailing lists,
newspaper, radio and television advertisements shall not constitute solicitation
under this Section, nor is the Servicer prohibited from responding to
unsolicited requests or inquiries made by a Mortgagor or an agent of a
Mortgagor. Furthermore, the Servicer shall be permitted to include in its
monthly statements to borrowers or otherwise, statements regarding the
availability of the Servicer's counseling services with respect to refinancing
mortgage loans.

            Section 3.31 Periodic Filings.

            (a) The Securities Administrator and the Servicer shall reasonably
cooperate with the Depositor in connection with the Trust's satisfying its
reporting requirements under the Exchange Act. Without limiting the generality
of the foregoing, the Securities Administrator shall prepare on behalf of the
Trust any monthly Current Reports on Form 8-K (each, a "Monthly Form 8-K") and
Annual Reports on Form 10-K (each, a "Form 10-K") customary for similar
securities as required by the Exchange Act and the rules and regulations of the
Securities and Exchange Commission thereunder, and the Securities Administrator
shall sign (other than any Form 10-K) and file (via the Securities and Exchange
Commission's Electronic Data Gathering and Retrieval System) such Forms on
behalf of the Trust. The Servicer shall sign any Form 10-K.

            (b) Each Monthly Form 8-K shall be filed by the Securities
Administrator within 15 days after each Distribution Date, including a copy of
the Distribution Date Statement for such Distribution Date as an exhibit
thereto. Prior to March 30th of each year (or such earlier date as may be
required by the Exchange Act and the rules and regulations of the Securities and
Exchange Commission), the Securities Administrator shall file a Form 10-K, in
substance as required by applicable law or applicable Securities and Exchange
Commission staff's interpretations. Such Form 10-K shall include as exhibits the
Servicer's annual statement of compliance described under Section 3.19 and the
accountant's report described under Section 3.20, in each case, to the extent
they have been timely delivered to the Securities Administrator. If they are not
so timely delivered, the Securities Administrator shall file an amended Form
10-K including such documents as exhibits reasonably promptly after they are
delivered to the Securities Administrator. The Securities Administrator shall
have no liability with respect to any failure to properly prepare or file such
periodic reports resulting from or relating to the Securities Administrator's
inability or failure to obtain any information not resulting from its own
negligence, willful misconduct or bad faith. The Form 10-K shall also include a
certification in the form attached hereto as Exhibit O (the "Certification"),
which shall be signed by a senior officer of the Servicer in charge of the
servicing function. The Servicer shall deliver the Certification to the Trustee
three (3) Business Days prior to the latest date on which the Form 10-K may be
timely filed. The Securities Administrator, the Depositor and the Servicer shall
reasonably cooperate to enable the Securities and Exchange Commission
requirements with respect to the Trust to be met in the event that the
Securities and Exchange Commission issues additional interpretive guidelines or
promulgates rules or regulations, or in the event of any other change of law
that would require reporting arrangements or the allocation of responsibilities
with respect thereto, as described in this Section 3.31, to be conducted or
allocated in a different manner.

            (c) Prior to the latest date on which the Form 10-K may be timely
filed each year, the Securities Administrator shall sign and deliver to the
Securities Administrator a certification (in the form attached hereto as Exhibit
P) for the benefit of the Depositor and its officers, directors and Affiliates
(provided, however, that the Securities Administrator shall not undertake an
analysis of the accountant's report attached as an exhibit to the Form 10-K). In
addition, (i) the Securities Administrator shall also indemnify and hold
harmless the Servicer and its officers, directors and Affiliates from and
against any losses, damages, penalties, fines, forfeitures, reasonable and
necessary legal fees and related costs, judgments and other costs and expenses
arising out of or based upon any inaccuracy in the certification provided by the
Securities Administrator pursuant to this Section 3.31(c), any breach of the
Securities Administrator's obligations under this Section 3.31(c) or the
Securities Administrator's negligence, bad faith or willful misconduct in
connection therewith. If the indemnification provided for herein is unavailable
or insufficient to hold harmless the Servicer and its officers, directors and
Affiliates, then the Securities Administrator agrees that it shall contribute to
the amount paid or payable by the Servicer, its officers, directors or
Affiliates as a result of the losses, claims, damages or liabilities of the
Servicer, its officers, directors or Affiliates in such proportion as is
appropriate to reflect the relative fault of the Servicer and its officers,
directors and Affiliates on the one hand and the Securities Administrator on the
other in connection with a breach of the Securities Administrator's obligations
under this Section 3.31(c) or the Securities Administrator's negligence, bad
faith or willful misconduct in connection therewith.

            (d) Upon any filing with the Securities and Exchange Commission, the
Securities Administrator shall promptly deliver to the Depositor and the
Servicer a copy of any such executed report, statement or information.

            (e) The obligations set forth in paragraphs (a) through (d) of this
Section shall only apply with respect to periods for which the Securities
Administrator is obligated to file reports on Form 8-K or 10-K pursuant to
paragraph (b) of this Section. Upon request of the Depositor, the Securities
Administrator shall prepare, execute and file with the Securities and Exchange
Commission a Form 15 Suspension Notification with respect to the Trust, and
thereafter there shall be no further obligations under paragraphs (a) through
(d) of this Section commencing with the calendar year in which the Form 15 is
filed (other than the obligations to be performed in such calendar year that
relate back to the prior calendar year).

registered owner of such Certificates, or by check mailed by first class mail to
the address of the Person entitled thereto, as such name and address shall
appear on the Certificate Register, provided that the Trustee may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Distributions among Certificateholders shall be made in proportion to the
Percentage Interests evidenced by the Certificates held by such
Certificateholders.

            Section 4.05 Distributions on Book-Entry Certificates.

            Each distribution with respect to a Book-Entry Certificate shall be
paid to the Depository, which shall credit the amount of such distribution to
the accounts of its Depository Participants in accordance with its normal
procedures. Each Depository Participant shall be responsible for disbursing such
distribution to the Certificate Owners that it represents and to each indirect
participating brokerage firm (a "brokerage firm" or "indirect participating
firm") for which it acts as agent. Each brokerage firm shall be responsible for
disbursing funds to the Certificate Owners that it represents. All such credits
and disbursements with respect to a Book-Entry Certificate are to be made by the
Depository and the Depository Participants in accordance with the provisions of
the Certificates. None of the Trustee, the Depositor or the Servicer shall have
any responsibility therefor except as otherwise provided by applicable law.

            Section 4.07 Remittance Reports; Advances.

            (a) On the 17th calendar day of each month, or the preceding
Business Day if such 17th calendar day is not a Business Day, the Servicer shall
deliver to the Securities Administrator by telecopy (or by such other means as
the Servicer and the Securities Administrator may agree from time to time) a
Remittance Report with respect to the related Distribution Date. On the same
date, the Servicer shall electronically forward to the Securities Administrator
in such medium as may be agreed between the Servicer and the Securities
Administrator the information set forth in such Remittance Report with respect
to the related Distribution Date and such information reasonably available to
the Servicer necessary in order for the Trustee to perform the calculations
necessary to make the distributions contemplated by Section 4.01, 4.02 and 4.03
and to prepare the Distribution Date Statement. The Trustee shall not be
responsible to recompute, recalculate or verify any information provided to it
by the Servicer.

            (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.07(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Collection Period in respect of the Mortgage Loans, which
Monthly Payments were delinquent on a contractual basis as of the close of
business on the related Determination Date and (ii) with respect to each REO
Property, which REO Property was acquired during or prior to the related
Collection Period and as to which REO Property an REO Disposition did not occur
during the related Collection Period, an amount equal to the excess, if any, of
the REO Imputed Interest on such REO Property for such Collection Period, over
the net income from such REO Property transferred to the Distribution Account
pursuant to Section 3.13 for distribution on such Distribution Date.

            On or before the close of business New York time on the Servicer
Remittance Date, the Servicer shall remit in immediately available funds to the
Trustee for deposit in the Distribution Account an amount equal to the aggregate
amount of Advances, if any, to be made in respect of the Mortgage Loans for the
related Distribution Date either (i) from its own funds or (ii) from the
Collection Account, to the extent of funds held therein for future distribution
(in which case it will cause to be made an appropriate entry in the records of
the Collection Account that amounts held for future distribution have been, as
permitted by this Section 4.07, used by the Servicer in discharge of any such
Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the
total amount of Advances to be made by the Servicer with respect to the Mortgage
Loans. Any amounts held for future distribution and so used shall be
appropriately reflected in the Servicer's records and replaced by the Servicer
by deposit in the Collection Account on or before any future Servicer Remittance
Date to the extent that the Available Funds for the related Distribution Date
(determined without regard to Advances to be made on the Servicer Remittance
Date) shall be less than the total amount that would be distributed to the
Classes of Certificateholders pursuant to Section 4.01 and 4.02 on such
Distribution Date if such amounts held for future distributions had not been so
used to make Advances. The Trustee will provide notice to the Servicer by
telecopy by the close of business on any Servicer Remittance Date in the event
that the amount remitted by the Servicer to the Trustee on such date is less
than the Advances required to be made by the Servicer for the related
Distribution Date, as set forth in the related Remittance Report.

            (c) The obligation of the Servicer to make such Advances is
mandatory, notwithstanding any other provision of this Agreement but subject to
(d) below, and, with respect to any Mortgage Loan, shall continue until the
earlier of such time as the Trust acquires title to the related Mortgaged
Property or such Mortgage Loan is paid in full by the Mortgagor or disposed of
by the Trust, or until the recovery of all Liquidation Proceeds thereon.

            (d) Notwithstanding anything herein to the contrary, no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer if such
Advance would, if made, constitute a Nonrecoverable Advance. The determination
by the Servicer that it has made a Nonrecoverable Advance or that any proposed
Advance, if made, would constitute a Nonrecoverable Advance, shall be evidenced
by an Officers' Certificate of the Servicer delivered to the Depositor, the
Securities Administrator and the Trustee.

            Interests are reduced to zero; then

                  (3) to REMIC 1 Regular Interest LT1ZZ, 1.00% of such

      related group of Mortgage Loans (except that if any such excess is a
      larger number than in the preceding distribution period, the least amount
      of principal shall be distributed to such REMIC 1 Regular Interests such

manually authenticated by the Certificate Registrar substantially in the form
provided for herein, and such authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Offered Certificates

Certificates shall not be Book-Entry Certificates but shall be issued in fully
registered certificate form.

            Section 5.02 Registration of Transfer and Exchange of Certificates.

            (a) The Certificate Registrar shall cause to be kept at the
Corporate Trust Office of the Trustee a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Certificate Registrar
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee shall initially serve
as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided. The Trustee as
Certificate Registrar shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall
apply to the Certificate Registrar to the same extent as they apply to the
Trustee. Any Certificate Registrar appointed in accordance with this Section
5.02(a) may at any time resign by giving at least 30 days' advance written
notice of resignation to the Trustee, the Securities Administrator, the Servicer
and the Depositor, such resignation to become effective upon appointment of a
successor Certificate Registrar.

            Upon surrender for registration of transfer of any Certificate at
any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of the Class R Certificate,
upon satisfaction of the conditions set forth below, the Trustee on behalf of
the Trust shall execute and the Certificate Registrar shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Certificates of the same aggregate Percentage Interest.

            At the option of the Certificateholders, Certificates may be
exchanged for other Certificates in authorized denominations and the same
aggregate Percentage Interests, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute on behalf of the Trust and
the Certificate Registrar shall authenticate and deliver the Certificates which
the Certificateholder making the exchange is entitled to receive. Every
Certificate presented or surrendered for registration of transfer or exchange
shall (if so required by the Trustee or the Certificate Registrar) be duly
endorsed by, or be accompanied by a written instrument of transfer satisfactory
to the Trustee and the Certificate Registrar duly executed by, the Holder
thereof or his attorney duly authorized in writing.

            (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository by, or on behalf of, the Depositor; or to, and deposited with the
Certificate Custodian, on behalf of the Depository, if directed to do so
pursuant to instructions from the Depository. Except as provided in paragraph
(c) below, the Book-Entry Certificates shall at all times remain registered in
the name of the Depository or its nominee and at all times: (i) registration of
such Certificates may not be transferred by the Trustee except to another
Depository; (ii) the Depository shall maintain book-entry records with respect
to the Certificate Owners and with respect to ownership and transfers of such
Certificates; (iii) ownership and transfers of registration of such Certificates
on the books of the Depository shall be governed by applicable rules established
by the Depository; (iv) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (v) the Trustee shall for
all purposes deal with the Depository as representative of the Certificate
Owners of the Certificates for purposes of exercising the rights of Holders
under this Agreement, and requests and directions for and votes of such
representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; (vi) the Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners; and (vii) the direct participants of the Depository shall have no rights
under this Agreement under or with respect to any of the Certificates held on
their behalf by the Depository, and the Depository may be treated by the Trustee
and its agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

            All transfers by Certificate Owners of Book-Entry Certificates shall
be made in accordance with the procedures established by the Depository
Participant or brokerage firm representing such Certificate Owners. Each
Depository Participant shall only transfer Book-Entry Certificates of
Certificate Owners that it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures. The parties hereto
are hereby authorized to execute a Letter of Representations with the Depository
or take such other action as may be necessary or desirable to register a
Book-Entry Certificate to the Depository. In the event of any conflict between
the terms of any such Letter of Representation and this Agreement, the terms of
this Agreement shall control.

            (c) If the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository and the Trustee or the Depositor is unable to
locate a qualified successor and upon surrender to the Certificate Registrar of
the Book-Entry Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall, at the
Trust's expense, execute on behalf of the Trust and the Certificate Registrar
shall authenticate definitive, fully registered certificates (the "Definitive
Certificates"). None of the Depositor or the Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be protected in relying on, such instructions. Upon the issuance of Definitive
Certificates, the Trustee, the Certificate Registrar, the Servicer, the
Securities Administrator, any Paying Agent and the Depositor shall recognize the
Holders of the Definitive Certificates as Certificateholders hereunder.

            (d) Except with respect to a transfer of the Private Certificates
between or among the Depositor, the Seller, their affiliates or both, no
transfer, sale, pledge or other disposition of any Private Certificate shall be
made unless such disposition is exempt from the registration requirements of the
1933 Act, and any applicable state securities laws or is made in accordance with
the 1933 Act and laws. In the event of any such transfer, (i) unless such
transfer is made in reliance upon Rule 144A (as evidenced by the investment
letter delivered to the Certificate Registrar, in substantially the form
attached hereto as Exhibit J) under the 1933 Act, the Certificate Registrar and
the Depositor shall require a written Opinion of Counsel (which may be in-house
counsel) acceptable to and in form and substance reasonably satisfactory to the
Certificate Registrar and the Depositor that such transfer may be made pursuant
to an exemption, describing the applicable exemption and the basis therefor,
from the 1933 Act or is being made pursuant to the 1933 Act, which Opinion of
Counsel shall not be an expense of the Certificate Registrar or the Depositor or
(ii) the Certificate Registrar shall require the transferor to execute a
transferor certificate (in substantially the form attached hereto as Exhibit L)
and the transferee to execute an investment letter (in substantially the form
attached hereto as Exhibit J) acceptable to and in form and substance reasonably
satisfactory to the Depositor and the Certificate Registrar certifying to the
Depositor and the Certificate Registrar the facts surrounding such transfer,
which investment letter shall not be an expense of the Certificate Registrar or
the Depositor. The Holder of a Private Certificate desiring to effect such
transfer shall, and does hereby agree to, indemnify the Certificate Registrar
and the Depositor against any liability that may result if the transfer is not
so exempt or is not made in accordance with such federal and state laws.

            No transfer of an ERISA-Restricted Certificate shall be made unless
the Certificate Registrar shall have received either (i) a representation from
the transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Certificate Registrar and the Depositor, (such requirement
is satisfied only by the Certificate Registrar's receipt of a representation
letter from the transferee substantially in the form of Exhibit I hereto, as
appropriate), to the effect that such transferee is not an employee benefit plan
or arrangement subject to Section 406 of ERISA or a plan subject to Section 4975
of the Code, nor a person acting on behalf of any such plan or arrangement nor
using the assets of any such plan or arrangement to effect such transfer or (ii)
(except in the case of a Class P, Class R or Class CE Certificate) if the
purchaser is an insurance company, a representation that the purchaser is an
insurance company which is purchasing such Certificates with funds contained in
an "insurance company general account" (as such term is defined in Section V(c)
of Prohibited Transaction Class Exemption 95-60 ("PTCE 95-60") and that the
purchase and holding of such Certificates are covered under Sections I and III
of PTCE 95-60 or (iii) (except in the case of the Class R Certificate) in the
case of any such ERISA Restricted Certificate presented for registration in the
name of an employee benefit plan subject to ERISA or a plan or arrangement
subject to Section 4975 of the Code (or comparable provisions of any subsequent
enactments), or a trustee of any such plan or any other person acting on behalf
of any such plan or arrangement or using such plan's or arrangement's assets, an
Opinion of Counsel satisfactory to the Certificate Registrar, to the effect that
the purchase or holding of such ERISA Restricted Certificate will not result in
the assets of the Trust being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA and the Code and will not subject the
Depositor, the Servicer, the Trustee or the Certificate Registrar to any
obligation in addition to those expressly undertaken in this Agreement or to any
liability. For purposes of clause (i) of the preceding sentence, such
representation shall be deemed to have been made to the Certificate Registrar by
the acceptance by a Certificate Owner of the beneficial interest in any such
Class of ERISA-Restricted Certificates, unless the Certificate Registrar shall
have received from the transferee an alternative representation acceptable in
form and substance to the Depositor. Notwithstanding anything else to the
contrary herein, any purported transfer of an ERISA-Restricted Certificate to or
on behalf of an employee benefit plan subject to ERISA or to the Code without
the delivery to the Certificate Registrar of an Opinion of Counsel satisfactory
to the Certificate Registrar as described above shall be void and of no effect.

            Each Person who has or who acquires any Ownership Interest in the
Class R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably appointed the Depositor or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (v) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in the Class R Certificate are expressly subject to the
following provisions:

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

            (ii) No Person shall acquire an Ownership Interest in the Class R
      Certificate unless such Ownership Interest is a pro rata undivided
      interest.

            (iii) In connection with any proposed transfer of any Ownership
      Interest in the Class R Certificate, the Certificate Registrar shall as a
      condition to registration of the transfer, require delivery to it, in form
      and substance satisfactory to it, of each of the following:

            A. an affidavit in the form of Exhibit K hereto from the proposed
transferee to the effect that, among other things, such transferee is a
Permitted Transferee and that it is not acquiring its Ownership Interest in the
Class R Certificate that is the subject of the proposed transfer as a nominee,
trustee or agent for any Person who is not a Permitted Transferee; and

            B. a covenant of the proposed transferee to the effect that the
proposed transferee agrees to be bound by and to abide by the transfer
restrictions applicable to the Class R Certificate.

            (iv) Any attempted or purported transfer of any Ownership Interest
      in the Class R Certificate in violation of the provisions of this Section
      shall be absolutely null and void and shall vest no rights in the
      purported transferee. If any purported transferee shall, in violation of
      the provisions of this Section, become the Holder of the Class R
      Certificate, then the prior Holder of such Class R Certificate that is a
      Permitted Transferee shall, upon discovery that the registration of
      transfer of such Class R Certificate was not in fact permitted by this
      Section, be restored to all rights as Holder thereof retroactive to the
      date of registration of transfer of such Class R Certificate. The
      Certificate Registrar shall be under no liability to any Person for any
      registration of transfer of the Class R Certificate that is in fact not
      permitted by this Section or for making any distributions due on such
      Class R Certificate to the Holder thereof or taking any other action with
      respect to such Holder under the provisions of this Agreement so long as
      the Certificate Registrar received the documents specified in clause
      (iii). The Trustee shall be entitled to recover from any Holder of the
      Class R Certificate that was in fact not a Permitted Transferee at the
      time such distributions were made all distributions made on such Class R
      Certificate. Any such distributions so recovered by the Trustee shall be
      distributed and delivered by the Trustee to the prior Holder of such Class
      R Certificate that is a Permitted Transferee.

            (v) If any Person other than a Disqualified Organization acquires
      any Ownership Interest in the Class R Certificate in violation of the
      restrictions in this Section, then the Certificate Registrar shall have
      the right but not the obligation, without notice to the Holder of the
      Class R Certificate or any other Person having an Ownership Interest
      therein, to notify the Depositor to arrange for the sale of the Class R
      Certificate. The proceeds of such sale, net of commissions (which may
      include commissions payable to the Depositor or its affiliates in
      connection with such sale), expenses and taxes due, if any, will be
      remitted by the Trustee to the previous Holder of the Class R Certificate
      that is a Permitted Transferee, except that in the event that the Trustee
      determines that the Holder of the Class R Certificate may be liable for
      any amount due under this Section or any other provisions of this
      Agreement, the Trustee may withhold a corresponding amount from such
      remittance as security for such claim. The terms and conditions of any
      sale under this clause (v) shall be determined in the sole discretion of
      the Trustee and it shall not be liable to any Person having an Ownership
      Interest in the Class R Certificate as a result of its exercise of such
      discretion.

            (vi) If any Person other than a Permitted Transferee acquires any
      Ownership Interest in the Class R Certificate in violation of the
      restrictions in this Section, then the Securities Administrator will
      provide to the Internal Revenue Service, and to the persons specified in
      Sections 860E(e)(3) and (6) of the Code, information needed to compute the
      tax imposed under Section 860E(e)(5) of the Code on transfers of residual
      interests to disqualified organizations. The Securities Administrator
      shall be entitled to reasonable compensation for providing such
      information from the person to whom it is provided.

The foregoing provisions of this Section shall cease to apply to transfers
occurring on or after the date on which there shall have been delivered to the
Certificate Registrar, in form and substance satisfactory to the Certificate
Registrar, (i) written notification from each Rating Agency that the removal of
the restrictions on Transfer set forth in this Section will not cause such
Rating Agency to downgrade its rating of the Certificates and (ii) an Opinion of
Counsel to the effect that such removal will not cause any REMIC hereunder to
fail to qualify as a REMIC.

            (e) No service charge shall be made for any registration of transfer
or exchange of Certificates of any Class, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

            All Certificates surrendered for registration of transfer or
exchange shall be cancelled by the Certificate Registrar and disposed of
pursuant to its standard procedures.

            Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

            If (i) any mutilated Certificate is surrendered to the Certificate
Registrar or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate and (ii) there is delivered to
the Trustee, the Depositor and the Certificate Registrar such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Trustee or the Certificate Registrar that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute on behalf of the Trust, and the Certificate Registrar shall authenticate
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like tenor and Percentage Interest.
Upon the issuance of any new Certificate under this Section, the Trustee or the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) in connection therewith. Any duplicate Certificate issued
pursuant to this Section, shall constitute complete and indefeasible evidence of
ownership in the Trust, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

            Section 5.04 Persons Deemed Owners.

            The Servicer, the Depositor, the Trustee, the Securities
Administrator, the Certificate Registrar, any Paying Agent and any agent of the
Servicer, the Depositor, the Certificate Registrar, any Paying Agent or the
Trustee may treat the Person, including a Depository, in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.01 and 4.02 and for all other
purposes whatsoever, and none of the Servicer, the Trust, the Trustee, the
Securities Administrator nor any agent of any of them shall be affected by
notice to the contrary.

            Section 5.05 Appointment of Paying Agent.

            The Paying Agent shall make distributions to Certificateholders from
the Distribution Account pursuant to Section 4.01 and 4.02 and shall report the
amounts of such distributions to the Trustee. The duties of the Paying Agent may
include the obligation to distribute statements and provide information to
Certificateholders as required hereunder. The Paying Agent hereunder shall at
all times be an entity duly incorporated and validly existing under the laws of
the United States of America or any state thereof, authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by
federal or state authorities. The Paying Agent shall initially be the Trustee.
The Trustee may appoint a successor to act as Paying Agent, which appointment
shall be reasonably satisfactory to the Depositor and the Rating Agencies. The
Trustee as Paying Agent shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall
apply to the Paying Agent to the same extent as they apply to the Trustee. Any
Paying Agent appointed in accordance with this Section 5.05 may at any time
resign by giving at least 30 days' advance written notice of resignation to the
Trustee, the Servicer and the Depositor, such resignation to become effective
upon appointment of a successor Paying Agent.

                                   ARTICLE VI

                         THE SERVICER AND THE DEPOSITOR

            Section 6.01 Liability of the Servicer and the Depositor.

            The Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by the
Servicer herein. The Depositor shall be liable in accordance herewith only to
the extent of the obligations specifically imposed upon and undertaken by the
Depositor.

            Section 6.02 Merger or Consolidation of, or Assumption of the
Obligations of, the Servicer or the Depositor.

            Any entity into which the Servicer or the Depositor may be merged or
consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Servicer or the Depositor shall be a party, or any
corporation succeeding to the business of the Servicer or the Depositor, shall
be the successor of the Servicer or the Depositor, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor servicer shall satisfy
all the requirements of Section 7.02 with respect to the qualifications of a
successor servicer.

            Section 6.03 Limitation on Liability of the Servicer and Others.

            Neither the Servicer nor any of the directors or officers or
employees or agents of the Servicer shall be under any liability to the Trust or
the Certificateholders for any action taken or for refraining from the taking of
any action by the Servicer in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of its willful misfeasance, bad faith or negligence in the
performance of duties of the Servicer or by reason of its reckless disregard of
its obligations and duties of the Servicer hereunder. The Servicer and any
director or officer or employee or agent of the Servicer may rely in good faith
on any document of any kind prima facie properly executed and submitted by any
Person respecting any matters arising hereunder. The Servicer and any director
or officer or employee or agent of the Servicer shall be indemnified by the
Trust and held harmless against any loss, liability or expense incurred in
connection with any legal action relating to this Agreement or the Certificates,
other than any loss, liability or expense related to any specific Mortgage Loan
or Mortgage Loans (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) and any loss, liability or
expense incurred by reason of its willful misfeasance, bad faith or negligence
in the performance of duties hereunder or by reason of its reckless disregard of
obligations and duties hereunder. The Servicer may undertake any such action
which it may deem necessary or desirable in respect of this Agreement, and the
rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In such event, the reasonable legal expenses and
costs of such action and any liability resulting therefrom shall be expenses,
costs and liabilities of the Trust and the Servicer shall be entitled to be
reimbursed therefor pursuant to Section 3.05. The Servicer's right to indemnity
or reimbursement pursuant to this Section shall survive any resignation or
termination of the Servicer pursuant to Section 6.04 or 7.01 with respect to any
losses, expenses, costs or liabilities arising prior to such resignation or
termination (or arising from events that occurred prior to such resignation or
termination). This paragraph shall apply to the Servicer solely in its capacity
as Servicer hereunder and in no other capacities.

            Section 6.04 Servicer Not to Resign.

            Subject to the provisions of Section 7.01 and Section 6.02, the
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or duties
hereunder are no longer permissible under applicable law or are in material
conflict by reason of applicable law with any other activities carried on by it
or its subsidiaries or Affiliates, the other activities of the Servicer so
causing such a conflict being of a type and nature carried on by the Servicer or
its subsidiaries or Affiliates at the date of this Agreement or (ii) upon
satisfaction of the following conditions: (a) the Servicer has proposed a
successor servicer to the Trustee and the Securities Administrator in writing
and such proposed successor servicer is reasonably acceptable to the Trustee and
the Securities Administrator; and (b) each Rating Agency shall have delivered a
letter to the Trustee prior to the appointment of the successor servicer stating
that the proposed appointment of such successor servicer as Servicer hereunder
will not result in the reduction or withdrawal of the then current rating of the
Regular Certificates or the ratings that are in effect; provided, however, that
no such resignation by the Servicer shall become effective until such successor
servicer or, in the case of (i) above, the Securities Administrator shall have
assumed the Servicer's responsibilities and obligations hereunder or the
Securities Administrator shall have designated a successor servicer in
accordance with Section 7.02. Any such resignation shall not relieve the
Servicer of responsibility for any of the obligations specified in Sections 7.01
and 7.02 as obligations that survive the resignation or termination of the
Servicer. Any such determination permitting the resignation of the Servicer
shall be evidenced by an Opinion of Counsel to such effect delivered to the
Trustee and the Securities Administrator.

            Section 6.05 Delegation of Duties.

            In the ordinary course of business, the Servicer at any time may
delegate any of its duties hereunder to any Person, including any of its
Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those set forth in Section 3.01. Such delegation shall not relieve
the Servicer of its liabilities and responsibilities with respect to such duties
and shall not constitute a resignation within the meaning of Section 6.04. The
Servicer shall provide the Trustee and the Rating Agencies with 60 days prior
written notice prior to the delegation of any of its duties to any Person other
than any of the Servicer's Affiliates or their respective successors and
assigns.

                                   ARTICLE VII

                                     DEFAULT

            Section 7.01 Servicer Events of Termination.

            (a) If any one of the following events ("Servicer Events of
Termination") shall occur and be continuing:

            (i) (A) The failure by the Servicer to make any Advance, Servicing
      Advance or to pay Compensating Interest; or (B) any other failure by the
      Servicer to deposit in the Collection Account or Distribution Account any
      deposit required to be made under the terms of this Agreement, which
      failure continues unremedied for a period of three Business Days after the
      first date on which written notice of such failure is given to the
      Servicer; or

            (ii) The failure by the Servicer duly to observe or perform, in any
      material respect, any other covenants, obligations or agreements of the
      Servicer as set forth in this Agreement, which failure continues
      unremedied for a period of 60 days, after the date (A) on which written
      notice of such failure, requiring the same to be remedied, shall have been
      given to the Servicer by the Trustee or by any Holder of a Regular
      Certificate evidencing at least 25% of the Voting Interests or (B) actual
      knowledge of such failure by a Servicing Officer of the Servicer; or

            (iii) The entry against the Servicer of a decree or order by a court
      or agency or supervisory authority having jurisdiction in the premises for
      the appointment of a trustee, conservator, receiver or liquidator in any
      insolvency, conservatorship, receivership, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding up or liquidation of its affairs, and the continuance of any such
      decree or order unstayed and in effect for a period of 60 days; or

            (iv) The Servicer shall voluntarily go into liquidation, consent to

      relating to all or substantially all of its property; or a decree or order
      of a court or agency or supervisory authority having jurisdiction in the
      premises for the appointment of a conservator, receiver, liquidator or
      similar person in any insolvency, readjustment of debt, marshalling of
      assets and liabilities or similar proceedings, or for the winding-up or
      liquidation of its affairs, shall have been entered against the Servicer
      and such decree or order shall have remained in force undischarged,
      unbonded or unstayed for a period of 60 days; or the Servicer shall admit
      in writing its inability to pay its debts generally as they become due,
      file a petition to take advantage of any applicable insolvency or
      reorganization statute, make an assignment for the benefit of its
      creditors or voluntarily suspend payment of its obligations; or

            (v) the Servicer becoming ineligible to service for both Fannie Mae
      and Freddie Mac (unless remedied within 90 days).

            (b) Then, and in each and every such case, so long as a Servicer
Event of Termination shall not have been remedied within the applicable grace
period, (x) with respect solely to clause (i)(A) above, if such Advance is not
made by 2:00 P.M., New York time, on the Business Day immediately following the
Servicer Remittance Date, the Trustee may terminate all of the rights and
obligations of the Servicer under this Agreement and the Securities
Administrator, or a successor servicer appointed in accordance with Section
7.02, shall immediately make such Advance and assume, pursuant to Section 7.02,
the duties of a successor servicer and (y) in the case of (i)(B), (ii), (iii),
(iv) and (v) above, the Trustee shall, at the direction of the Holders of each
Class of Regular Certificates evidencing Percentage Interests aggregating not
less than 51%, by notice then given in writing to the Servicer (and to the
Trustee if given by Holders of Certificates), terminate all of the rights and
obligations of the Servicer as servicer under this Agreement. Any such notice to
the Servicer shall also be given to each Rating Agency and the Depositor. On or
after the receipt by the Servicer (and by the Trustee if such notice is given by
the Holders) of such written notice, all authority and power of the Servicer
under this Agreement, whether with respect to the Certificates or the Mortgage
Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and
under this Section or successor servicer appointed in connection with Section
7.02; and, without limitation, the Securities Administrator or successor
servicer is hereby authorized and empowered to execute and deliver, on behalf of
the Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and Related
Documents or otherwise. The Servicer agrees to cooperate with the Securities
Administrator (or the applicable successor servicer) in effecting the
termination of the responsibilities and rights of the Servicer hereunder,
including, without limitation, the delivery to the Securities Administrator (or
the applicable successor servicer) of all documents and records requested by it
to enable it to assume the Servicer's functions under this Agreement within ten
Business Days subsequent to such notice, the transfer within one Business Day
subsequent to such notice to the Securities Administrator (or the applicable
successor servicer) for the administration by it of all cash amounts that shall
at the time be held by the Servicer and to be deposited by it in the Collection
Account, the Distribution Account or any Escrow Account or that have been
deposited by the Servicer in such accounts or thereafter received by the
Servicer with respect to the Mortgage Loans or any REO Property received by the
Servicer. All reasonable out-of-pocket costs and expenses (including attorneys'
fees) incurred in connection with transferring the servicing to the successor
servicer and amending this Agreement to reflect such succession as Servicer
pursuant to this Section shall be paid by the predecessor servicer (or if the
predecessor servicer is the Securities Administrator, the initial servicer) upon
presentation of reasonable documentation of such costs and expenses, and if such
predecessor Servicer defaults in its obligation to pay such costs, such costs
shall be paid by the successor Servicer or the Securities Administrator (in
which case the successor Servicer or the Securities Administrator shall be
entitled to reimbursement therefor from the assets of the Trust).

            Notwithstanding any termination of the activities of a Servicer
hereunder, the Servicer shall be entitled to receive payment of all accrued and
unpaid Servicing Fees and reimbursement for all outstanding Advances and
Servicing Advances properly made prior to the date of termination.

            Section 7.02 Securities Administrator to Act; Appointment of
Successor.

            (a) Within 90 days of the time the Servicer (and the Trustee, if
notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Securities Administrator (or such other successor
servicer as is approved in accordance with this Agreement) shall be the
successor in all respects to the Servicer in its capacity as servicer under this
Agreement and the transactions set forth or provided for herein and shall be
subject to all the responsibilities, duties and liabilities relating thereto
placed on the Servicer by the terms and provisions hereof arising on and after
its succession. As compensation therefor, the Securities Administrator (or such
other successor servicer) shall be entitled to such compensation as the Servicer
would have been entitled to hereunder if no such notice of termination had been
given. Notwithstanding the above, (i) if the Securities Administrator is
unwilling to act as successor servicer or (ii) if the Securities Administrator
is legally unable so to act, the Securities Administrator shall appoint or
petition a court of competent jurisdiction to appoint, any established housing
and home finance institution, bank or other mortgage loan or home equity loan
servicer having a net worth of not less than $50,000,000 as the successor to the
Servicer hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the Servicer hereunder; provided, that the appointment
of any such successor servicer will not result in the qualification, reduction
or withdrawal of the ratings assigned to the Certificates or the ratings that
are in effect by the Rating Agencies as evidenced by a letter to such effect
from the Rating Agencies. Pending appointment of a successor to the Servicer
hereunder, unless the Securities Administrator is prohibited by law from so
acting, the Securities Administrator shall act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the successor
shall be entitled to receive compensation out of payments on Mortgage Loans in
an amount equal to the compensation which the Servicer would otherwise have
received pursuant to Section 3.18 (or such other compensation as the Securities
Administrator and such successor shall agree, not to exceed the Servicing Fee).
The successor servicer shall be entitled to withdraw from the Collection Account
all costs and expenses associated with the transfer of the servicing to the
successor servicer, including costs and expenses of the Securities
Administrator. The appointment of a successor servicer shall not affect any
liability of the predecessor servicer which may have arisen under this Agreement
prior to its termination as Servicer to pay any deductible under an insurance
policy pursuant to Section 3.12 or to indemnify the parties indicated in Section
3.26 pursuant to the terms thereof, nor shall any successor servicer be liable
for any acts or omissions of the predecessor servicer or for any breach by such
servicer of any of its representations or warranties contained herein or in any
related document or agreement. The Securities Administrator and such successor
shall take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

            (b) Any successor, including the Securities Administrator, to the
Servicer as servicer shall during the term of its service as servicer continue
to service and administer the Mortgage Loans for the benefit of
Certificateholders, and maintain in force a policy or policies of insurance
covering errors and omissions in the performance of its obligations as Servicer
hereunder and a Fidelity Bond in respect of its officers, employees and agents
to the same extent as the Servicer is so required pursuant to Section 3.12.

            Section 7.03 Waiver of Defaults.

            The Holders of Certificates entitled to at least 66 2/3% of the
Voting Interests allocated to the Classes of Certificates affected by a Servicer
Event of Termination may, on behalf of all Certificateholders, waive any events
permitting removal of the Servicer as servicer pursuant to this Article VII,
provided, however, that such Holders may not waive a default in making a
required distribution on a Certificate without the consent of the Holder of such
Certificate. Upon any waiver of a past default, such default shall cease to
exist and any Servicer Event of Termination arising therefrom shall be deemed to
have been remedied for every purpose of this Agreement. No such waiver shall
extend to any subsequent or other default or impair any right consequent thereto
except to the extent expressly so waived. Notice of any such waiver shall be
given by the Trustee to the Securities Administrator and the Rating Agencies.

            Section 7.04 Notification to Certificateholders.

            (a) On any termination or appointment of a successor to the Servicer
pursuant to this Article VII or Section 6.04, the Trustee shall give prompt
written notice thereof to the Securities Administrator and the
Certificateholders at their respective addresses appearing in the Certificate
Register and each Rating Agency.

            (b) No later than 60 days after the occurrence of any event which
constitutes or which, with notice or a lapse of time or both, would constitute a
Servicer Event of Termination for five Business Days after a Responsible Officer
of the Trustee becomes aware of the occurrence of such an event, the Trustee
shall transmit by mail to the Securities Administrator and all
Certificateholders notice of such occurrence unless such default or Servicer
Event of Termination shall have been waived or cured. Such notice shall be given
to the Rating Agencies promptly after any such occurrence.

            Section 7.05 Survival of Servicer Liabilities.

            Notwithstanding anything herein to the contrary, upon termination of
the Servicer hereunder, any liabilities of the Servicer which accrued prior to
such termination shall survive such termination.

                                  ARTICLE VIII

                  THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

            Section 8.01 Duties of Trustee and Securities Administrator.

            The Trustee, prior to the occurrence of a Servicer Event of
Termination of which a Responsible Officer of the Trustee shall have actual
knowledge and after the curing of all Servicer Events of Termination which may
have occurred, and the Securities Administrator, each undertakes to perform such
duties and only such duties as are specifically set forth in this Agreement as
duties of the Trustee and the Securities Administrator, respectively. If a
Servicer Event of Termination has occurred (which has not been cured), the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

            Upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments furnished to the Trustee and the
Securities Administrator which are specifically required to be furnished
pursuant to any provision of this Agreement, the Trustee and the Securities
Administrator shall examine them to determine whether they conform to the
requirements of this Agreement; provided, however, that neither the Trustee or
the Securities Administrator shall be responsible for the accuracy or content of
any resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by the Servicer, the Seller or the Depositor
hereunder. If any such instrument is found not to conform in any material
respect to the requirements of this Agreement, the Trustee shall notify the
Certificateholders of such instrument in the event that the Trustee, after so
requesting, does not receive a satisfactorily corrected instrument.

            No provision of this Agreement shall be construed to relieve the
Trustee and the Securities Administrator from liability for its own negligent
action, its own negligent failure to act or its own misconduct; provided,
however, that:

            (i) prior to the occurrence of a Servicer Event of Termination, and
      after the curing of all such Servicer Events of Termination which may have
      occurred, the duties and obligations of the Trustee and the Securities
      Administrator shall be determined solely by the express provisions of this
      Agreement, neither the Trustee nor the Securities Administrator shall be
      liable except for the performance of such duties and obligations as are
      specifically set forth in this Agreement, no implied covenants or
      obligations shall be read into this Agreement against the Trustee and the
      Securities Administrator and, in the absence of bad faith on the part of
      the Trustee or the Securities Administrator, the Trustee or the Securities
      Administrator, as the case may be, may conclusively rely, as to the truth
      of the statements and the correctness of the opinions expressed therein,
      upon any certificates or opinions furnished to the Trustee or the
      Securities Administrator and conforming to the requirements of this
      Agreement;

            (ii) neither the Trustee nor the Securities Administrator shall be
      personally liable for an error of judgment made in good faith by a
      Responsible Officer of the Trustee or the Securities Administrator, unless
      it shall be proved that the Trustee or the Securities Administrator,
      respectively, was negligent in ascertaining or investigating the facts
      related thereto

            (iii) neither the Trustee nor the Securities Administrator shall be
      personally liable with respect to any action taken, suffered or omitted to
      be taken by it in good faith in accordance with the direction of the
      Majority Certificateholders relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee or the
      Securities Administrator or exercising or omitting to exercise any trust
      or power conferred upon the Trustee or the Securities Administrator under
      this Agreement; and

            (iv) neither the Trustee nor the Securities Administrator shall be
      charged with knowledge of any failure by the Servicer to comply with the
      obligations of the Servicer referred to in clauses (i) and (ii) of Section
      7.01(a) or any Servicer Event of Termination unless a Responsible Officer
      of the Trustee or the Securities Administrator obtains actual knowledge of
      such failure or the Trustee or the Securities Administrator receives
      written notice of such failure from the Servicer or the Majority
      Certificateholders.

            Neither the Trustee nor the Securities Administrator shall be
required to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder, or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it, and none of the provisions contained in this
Agreement shall in any event require the Trustee or the Securities Administrator
to perform, or be responsible for the manner of performance of, any of the
obligations of the Servicer under this Agreement, except during such time, if
any, as the Securities Administrator shall be the successor to, and be vested
with the rights, duties, powers and privileges of, the Servicer in accordance
with the terms of this Agreement.

            Section 8.02 Certain Matters Affecting the Trustee and the
Securities Administrator.

            (a) Except as otherwise provided in Section 8.01:

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

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

            (iii) neither the Trustee nor the Securities Administrator shall be
      under any obligation to exercise any of the rights or powers vested in it
      by this Agreement, or to institute, conduct or defend any litigation
      hereunder or in relation hereto, at the request, order or direction of the
      Certificateholders pursuant to the provisions of this Agreement, unless
      such Certificateholders shall have offered to the Trustee or the
      Securities Administrator, as the case may be, reasonable security or
      indemnity against the costs, expenses and liabilities which may be
      incurred therein or thereby; the right of the Trustee or the Securities
      Administrator to perform any discretionary act enumerated in this
      Agreement shall not be construed as a duty, and neither the Trustee nor
      the Securities Administrator shall be answerable for other than its
      negligence or willful misconduct in the performance of any such act;

            (iv) neither the Trustee nor the Securities Administrator shall be
      personally liable for any action taken, suffered or omitted by it in good
      faith and believed by it to be authorized or within the discretion or
      rights or powers conferred upon it by this Agreement;

            (v) prior to the occurrence of a Servicer Event of Termination and
      after the curing of all Servicer Events of Termination which may have
      occurred, neither the Trustee nor the Securities Administrator shall be
      bound to make any investigation into the facts or matters stated in any
      resolution, certificate, statement, instrument, opinion, report, notice,
      request, consent, order, approval, bond or other paper or documents,
      unless requested in writing to do so by the Majority Certificateholders;
      provided, however, that if the payment within a reasonable time to the
      Trustee or the Securities Administrator of the costs, expenses or
      liabilities likely to be incurred by it in the making of such
      investigation is, in the opinion of the Trustee or the Securities
      Administrator, not reasonably assured to the Trustee or the Securities
      Administrator by the security afforded to it by the terms of this
      Agreement, the Trustee and the Securities Administrator may require
      reasonable indemnity against such cost, expense or liability as a
      condition to such proceeding. The reasonable expense of every such
      examination shall be paid by the Servicer or, if paid by the Trustee or
      the Securities Administrator, shall be reimbursed by the Servicer upon
      demand. Nothing in this clause (v) shall derogate from the obligation of
      the Servicer to observe any applicable law prohibiting disclosure of
      information regarding the Mortgagors;

            (vi) neither the Trustee nor the Securities Administrator shall be
      accountable, have any liability or make any representation as to any acts
      or omissions hereunder of the Servicer until such time as the Securities
      Administrator may be required to act as Servicer pursuant to Section 7.02;

            (vii) each of the Trustee and the Securities Administrator may
      execute any of the trusts or powers hereunder or perform any duties
      hereunder either directly or by or through agents or attorneys or a
      custodian and neither the Trustee nor the Securities Administrator shall
      be responsible for any misconduct or negligence on the part of any such
      agent, attorney or custodian appointed by it with due care; and

            (viii) the right of the Trustee or the Securities Administrator to
      perform any discretionary act enumerated in this Agreement shall not be
      construed as a duty, and neither the Trustee nor the Securities
      Administrator shall be answerable for other than its negligence or willful
      misconduct in the performance of such act.

            Section 8.03 Trustee and Securities Administrator Not Liable for
Certificates or Mortgage Loans.

            The recitals contained herein and in the Certificates (other than
the authentication of the Trustee on the Certificates) shall be taken as the
statements of the Depositor, and neither the Trustee nor the Securities
Administrator assumes any responsibility for the correctness of the same.
Neither the Trustee nor the Securities Administrator makes any representations
as to the validity or sufficiency of this Agreement or of the Certificates
(other than the signature and authentication of the Trustee on the Certificates,
in the case of the Trustee) or of any Mortgage Loan or Related Document. Neither
the Trustee nor the Securities Administrator shall be accountable for the use or
application by the Servicer, or for the use or application of any funds paid to
the Servicer in respect of the Mortgage Loans or deposited in or withdrawn from
the Collection Account by the Servicer. Neither the Trustee nor the Securities
Administrator shall at any time have any responsibility or liability for or with
respect to the legality, validity and enforceability of any Mortgage or any
Mortgage Loan, or the perfection and priority of any Mortgage or the maintenance
of any such perfection and priority, or for or with respect to the sufficiency
of the Trust or its ability to generate the payments to be distributed to
Certificateholders under this Agreement, including, without limitation: the
existence, condition and ownership of any Mortgaged Property; the existence and
enforceability of any hazard insurance thereon (other than the Securities
Administrator's responsibility if the Securities Administrator shall assume the
duties of the Servicer pursuant to Section 7.02); the validity of the assignment
of any Mortgage Loan to the Trustee or of any intervening assignment; the
completeness of any Mortgage Loan; the performance or enforcement of any
Mortgage Loan (other than the Securities Administrator's responsibility if the
Securities Administrator shall assume the duties of the Servicer pursuant to
Section 7.02); the compliance by the Depositor or the Servicer with any warranty
or representation made under this Agreement or in any related document or the
accuracy of any such warranty or representation (except, in the case of the
Trustee, after receipt of notice of any non-compliance therewith or any breach
thereof); any investment of monies by or at the direction of the Servicer or any
loss resulting therefrom, it being understood that the Trustee shall remain
responsible for any Trust property that it may hold in its individual capacity;
the acts or omissions of any of the Servicer (other than the Securities
Administrator's responsibility if the Securities Administrator shall assume the
duties of the Servicer pursuant to Section 7.02), or any Mortgagor; any action
of the Servicer (other than the Securities Administrator's responsibility if the
Securities Administrator shall assume the duties of the Servicer pursuant to
Section 7.02), taken in the name of the Trust; the failure of the Servicer to
act or perform any duties required of it as agent of the Trust hereunder (other
than the Securities Administrator's responsibility if the Securities
Administrator shall assume the duties of the Servicer pursuant to Section 7.02);
or any action by the Trustee or the Securities Administrator taken at the
instruction of the Servicer (other than the Securities Administrator's
responsibility if the Securities Administrator shall assume the duties of the
Servicer pursuant to Section 7.02); provided, however, that the foregoing shall
not relieve the Trustee and the Securities Administrator of their obligation to
perform their respective duties under this Agreement. The Trustee shall have no
responsibility for filing any financing or continuation statement in any public
office at any time or to otherwise perfect or maintain the perfection of any
security interest or lien granted to it hereunder.

            Section 8.04 Trustee and Securities Administrator May Own
Certificates.

            Each of the Trustee and the Securities Administrator in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights as it would have if it were not Trustee or Securities
Administrator and may transact any banking and trust business with the Servicer,
the Depositor or their Affiliates.

            Section 8.05 Securities Administrator and Custodian Fees and
Expenses.

            The Securities Administrator shall be entitled to the Securities
Administrator Fee plus investment income on funds on deposit in the Distribution
Account as set forth in Section 3.25. This shall constitute compensation to the
Securities Administrator for its activities hereunder. The fees and expenses of
the Trustee shall be paid in accordance with a side letter agreement between the
Trustee and the Securities Administrator. The Trustee shall withdraw from the
Distribution Account on each Distribution Date and pay to the Securities
Administrator the Securities Administrator Fee pursuant to Section 4.01(i). The
Trust shall reimburse the Trustee and the Securities Administrator for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
or the Securities Administrator in accordance with any of the provisions of this
Agreement (including the reasonable compensation and the expenses and
disbursements of its counsel and of all persons not regularly in its employ),
pursuant to Section 4.01(ii), except any such expense, disbursement or advance
as may arise from its negligence or bad faith or which is the responsibility of
Certificateholders or the Trustee or Securities Administrator hereunder. In
addition, the Trustee, the Securities Administrator and their respective
officers, directors, employees and agents shall be indemnified by the Trust
from, and held harmless against, any and all losses, liabilities, damages,
claims or expenses incurred in connection with any legal action relating to this
Agreement or the Certificates, other than any loss, liability or expense (i)
that constitutes a specific liability of the Trustee or the Securities
Administrator under this Agreement or (ii) incurred by reason of willful
misfeasance, bad faith or negligence of the Trustee or Securities Administrator
in the performance of their respective duties hereunder or by reason of the
Trustee's or the Securities Administrator's, as the case may be, reckless
disregard of obligations and duties hereunder. The Custodian and its officers,
directors, employees and agents shall be indemnified by the Trust from, and held
harmless against, any and all losses, liabilities, damages, claims or expenses,
including reasonable attorneys' fees, that may be imposed on, incurred by or
asserted against it or them in any way related to or arising out of the Custody
Agreement, to the extent not provided for in the Custody Agreement, or any
action taken or not taken by it or them under the Custody Agreement, other than
any loss, liability or expense (i) that constitutes a specific liability of the
Custodian under the Custody Agreement or (ii) or incurred by reason of willful
misfeasance, bad faith or negligence of the Custodian in the performance of its
duties under the Custody Agreement or by reason of the Custodian's reckless
disregard of its obligations under the Custody Agreement. Subject to the
provisions of this Article VIII, the Trustee and its officers, directors,
employees and agents shall be indemnified by the Securities Administrator from,
and held harmless against, any and all losses, liabilities, damages, claims or
expenses incurred by the Trustee in connection with or arising out of the
willful misfeasance, bad faith or negligence of the Securities Administrator in
the performance of its duties under this Agreement or by reason of the
Securities Administrator's reckless disregard of its obligations and duties
under this Agreement. Subject to the provisions of this Article VIII, the
Securities Administrator and its officers, directors, employees and agents shall
be indemnified by the Trustee from, and held harmless against, any and all
losses, liabilities, damages, claims or expenses incurred by the Securities
Administrator in connection with or arising out of willful misfeasance, bad
faith or negligence of the Trustee in the performance of its duties under this
Agreement or by reason of the Trustee's reckless disregard of its obligations
and duties under this Agreement. This Section shall survive termination of this
Agreement or the resignation or removal of any Trustee or Securities
Administrator hereunder.

            Section 8.06 Eligibility Requirements for Trustee and Securities
Administrator.

            Each of the Trustee and the Securities Administrator shall at all
times be an entity duly organized and validly existing under the laws of the
United States of America or any state thereof, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000 and a minimum long-term debt rating of BBB by Fitch and S&P
and Baa3 by Moody's and a long term debt rating of at least A1 or better by
Moody's, and subject to supervision or examination by federal or state
authority. If such entity publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 8.06, the combined capital and
surplus of such entity shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. The principal
office of the Trustee and the Securities Administrator (other than the initial
Trustee or Securities Administrator) shall be in a state with respect to which
an Opinion of Counsel has been delivered to such Trustee or Securities
Administrator at the time such Trustee or Securities Administrator is appointed
Trustee or Securities Administrator, at such entity's expense, to the effect
that the Trust will not be a taxable entity under the laws of such state. In
case at any time the Trustee or Securities Administrator shall cease to be
eligible in accordance with the provisions of this Section 8.06, the Trustee or
Securities Administrator shall resign immediately in the manner and with the
effect specified in Section 8.07.

            Section 8.07 Resignation or Removal of Trustee and Securities
Administrator.

            The Trustee or the Securities Administrator may at any time resign
and be discharged from the trusts hereby created by giving written notice
thereof to the Depositor, the Servicer and each Rating Agency. Upon receiving
such notice of resignation, the Depositor shall promptly appoint a successor
Trustee or Securities Administrator by written instrument, in duplicate, one
copy of which instrument shall be delivered to the resigning Trustee or
Securities Administrator and one copy to the successor Trustee or Securities
Administrator. If no successor Trustee or Securities Administrator shall have
been so appointed and having accepted appointment within 30 days after the
giving of such notice of resignation, the resigning Trustee or Securities
Administrator may petition any court of competent jurisdiction for the
appointment of a successor Trustee or Securities Administrator.

            If at any time the Trustee or the Securities Administrator shall
cease to be eligible in accordance with the provisions of Section 8.06 and shall
fail to resign after written request therefor by the Depositor, or if at any
time the Trustee or the Securities Administrator shall be legally unable to act,
or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or
the Securities Administrator or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or the Securities
Administrator or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Depositor may remove the Trustee or the
Securities Administrator, as the case may be. If the Depositor or the Servicer
removes the Trustee or the Securities Administrator under the authority of the
immediately preceding sentence, the Depositor shall promptly appoint a successor
Trustee or Securities Administrator by written instrument, in duplicate, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor Trustee or Securities Administrator.

            The Majority Certificateholders may at any time remove the Trustee
or the Securities Administrator by written instrument or instruments delivered
to the Servicer, the Depositor, the Securities Administrator and the Trustee;
the Depositor shall thereupon use its best efforts to appoint a successor
Trustee or Securities Administrator in accordance with this Section.

            Any resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor Trustee or Securities Administrator
pursuant to any of the provisions of this Section 8.07 shall not become
effective until acceptance of appointment by the successor Trustee or Securities
Administrator as provided in Section 8.08.

            Section 8.08 Successor Trustee and Successor Securities
Administrator.

            Any successor Trustee or Securities Administrator appointed as
provided in Section 8.07 shall execute, acknowledge and deliver to the
Depositor, the Rating Agencies, the Servicer and to its predecessor Trustee or
Securities Administrator an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Trustee or Securities
Administrator shall become effective, and such successor Trustee or Securities
Administrator, without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as Trustee or Securities
Administrator. The Depositor, the Servicer and the predecessor Trustee or
Securities Administrator shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee or Securities Administrator all such rights,
powers, duties and obligations.

            No successor Trustee or Securities Administrator shall accept
appointment as provided in this Section 8.08 unless at the time of such
acceptance such successor Trustee or Securities Administrator shall be eligible
under the provisions of Section 8.06 and the appointment of such successor
Trustee or Securities Administrator shall not result in a downgrading of the
Regular Certificates by any Rating Agency, as evidenced by a letter from each
Rating Agency.

            Upon acceptance of appointment by a successor Trustee or Securities
Administrator as provided in this Section 8.08, the successor Trustee or
Securities Administrator shall mail notice of the appointment of a successor
Trustee hereunder to all Holders of Certificates at their addresses as shown in
the Certificate Register and to each Rating Agency.

            Section 8.09 Merger or Consolidation of Trustee or Securities
Administrator.

            Any entity into which the Trustee or the Securities Administrator
may be merged or converted or with which it may be consolidated, or any entity
resulting from any merger, conversion or consolidation to which the Trustee or
the Securities Administrator shall be a party, or any entity succeeding to the
business of the Trustee or the Securities Administrator, shall be the successor
of the hereunder, provided such entity shall be eligible under the provisions of
Section 8.06 and 8.08, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

            Section 8.10 Appointment of Co-Trustee or Separate Trustee.

            Notwithstanding any other provisions of this Agreement, at any time,
for the purpose of meeting any legal requirements of any jurisdiction in which
any part of the Trust or any Mortgaged Property may at the time be located, the
Depositor and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Certificateholders, such title to the Trust, or any part thereof, and, subject
to the other provisions of this Section 8.10, such powers, duties, obligations,
rights and trusts as the Servicer and the Trustee may consider necessary or
desirable. Any such co-trustee or separate trustee shall be subject to the
written approval of the Servicer. If the Servicer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
the case a Servicer Event of Termination shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee hereunder shall be required to meet the terms of eligibility
as a successor Trustee under Section 8.06, and no notice to Certificateholders
of the appointment of any co-trustee or separate trustee shall be required under
Section 8.08. The Servicer shall be responsible for the fees of any co-trustee
or separate trustee appointed hereunder.

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

            (i) all rights, powers, duties and obligations conferred or imposed
      upon the Trustee shall be conferred or imposed upon and exercised or
      performed by the Trustee and such separate trustee or co-trustee jointly
      (it being understood that such separate trustee or co-trustee is not
      authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed, the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations (including the holding of
      title to the Trust or any portion thereof in any such jurisdiction) shall
      be exercised and performed singly by such separate trustee or co-trustee,
      but solely at the direction of the Trustee;

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

            (iii) the Securities Administrator and the Trustee, acting jointly
      may at any time accept the resignation of or remove any separate trustee
      or co-trustee.

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

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

            Section 8.11 Limitation of Liability.

            The Certificates are executed by the Trustee, not in its individual
capacity but solely as Trustee of the Trust, in the exercise of the powers and
authority conferred and vested in it by this Agreement. Each of the undertakings
and agreements made on the part of the Trustee in the Certificates is made and
intended not as a personal undertaking or agreement by the Trustee but is made
and intended for the purpose of binding only the Trust.

            Section 8.12 Trustee May Enforce Claims Without Possession of
Certificates.

            (a) All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee for the benefit of all
Holders of such Certificates, subject to the provisions of this Agreement. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Certificateholders in respect of
which such judgment has been recovered.

            (b) The Trustee shall afford the Depositor, the Servicer, the
Securities Administrator and each Certificateholder upon reasonable notice
during normal business hours, access to all records maintained by the Trustee in
respect of its duties hereunder and access to officers of the Trustee
responsible for performing such duties. The Trustee shall cooperate fully with
the Servicer, the Depositor, the Securities Administrator and such
Certificateholder and shall make available to the Servicer, the Depositor, the
Securities Administrator and such Certificateholder for review and copying at
the expense of the party requesting such copies, such books, documents or
records as may be requested with respect to the Trustee's duties hereunder. The
Depositor, the Servicer, the Securities Administrator and the Certificateholders
shall not have any responsibility or liability for any action or failure to act
by the Trustee and are not obligated to supervise the performance of the Trustee
under this Agreement or otherwise.

            Section 8.13 Suits for Enforcement.

            In case a Servicer Event of Termination or other default by the
Servicer hereunder shall occur and be continuing, the Trustee may proceed to
protect and enforce its rights and the rights of the Certificateholders under
this Agreement by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this Agreement
or for the enforcement of any other legal, equitable or other remedy, as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual to protect and enforce any of the rights of the Trustee and the
Certificateholders.

            Section 8.14 Waiver of Bond Requirement.

            The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee post a bond or other surety with any
court, agency or body whatsoever.

            Section 8.15 Waiver of Inventory, Accounting and Appraisal
Requirement.

            The Trustee shall be relieved of, and each Certificateholder hereby
waives, any requirement of any jurisdiction in which the Trust, or any part
thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

            Section 8.16 Appointment of Custodian.

            Wells Fargo Bank, National Association, has been appointed Custodian
by the Trustee pursuant to the Custody Agreement. If such entity resigns or is
terminated as Custodian pursuant to the Custody Agreement, the Trustee shall
serve as Custodian or the Trustee may, with the consent of the Depositor and the
Servicer, appoint one or more Custodians to hold all or a portion of the
Mortgage Files as agent for the Trustee, by entering into a custodial agreement
in the form of the Custody Agreement or otherwise in a form acceptable to the
Depositor and the Servicer. Subject to this Article VIII, the Trustee agrees to
comply with the terms of the Custody Agreement and any such custodial agreement
and to enforce the terms and provisions thereof against the Custodian for the
benefit of the Certificateholders. Each Custodian will be a depositary
institution subject to supervision by federal or state authority, shall have a
combined capital and surplus of at least $10,000,000 and shall be qualified to
do business in the jurisdiction in which it holds any Mortgage File and afforded
the same protections hereunder as the Trustee.

                                   ARTICLE IX

                     REMIC AND GRANTOR TRUST ADMINISTRATION

            Section 9.01 REMIC Administration.

            (a) The Trustee shall make or cause to be made REMIC elections for
each of REMIC 1 and REMIC 2 as set forth in the Preliminary Statement on Forms
1066 as prepared by the Securities Administrator or other appropriate federal
tax or information return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued. The Securities Administrator
shall prepare such Forms 1066 and any other appropriate federal tax or
information return and deliver them to the Trustee on a timely basis for the
Trustee's execution. The Trustee shall execute and file such forms. The regular
interests and residual interest in each REMIC shall be as designated in the
Preliminary Statement.

            (b) The Closing Date is hereby designated as the "Startup Day" of
each REMIC within the meaning of section 860G(a)(9) of the Code.

            (c) The Securities Administrator shall pay any and all tax related
expenses (not including taxes) of each REMIC, including but not limited to any
professional fees or expenses related to audits or any administrative or
judicial proceedings with respect to such REMIC that involve the Internal
Revenue Service or state tax authorities, but only to the extent that (i) such
expenses are ordinary or routine expenses, including expenses of a routine audit
but not expenses of litigation (except as described in (ii)); or (ii) such
expenses or liabilities (including taxes and penalties) are attributable to the
negligence or willful misconduct of the Securities Administrator in fulfilling
its duties hereunder. The Securities Administrator shall be entitled to
reimbursement of expenses to the extent provided in clause (i) above from the
Trust.

            (d) The Securities Administrator shall prepare or cause to be
prepared, sign and file or cause to be filed, each REMIC's federal and state tax
and information returns as such REMIC's direct representative. The expenses of
preparing and filing such returns shall be borne by the Securities
Administrator. The Securities Administrator will apply for an Employer
Identification Number from the Internal Revenue Service via a form SS-4 or any
other acceptable method for all REMICs and other tax entities and will also file
a Form 8811 with respect to all such REMICs with the Internal Revenue Service.

            (e) The Holder of the Class R Certificate shall be the "tax matters
person" as defined in the REMIC Provisions (the "Tax Matters Person") with
respect to each REMIC, and the Securities Administrator is irrevocably
designated as and shall act as attorney-in-fact and agent for such Tax Matters
Person for each REMIC. The Securities Administrator, as agent for the Tax
Matters Person, shall perform, on behalf of each REMIC, all reporting and other
tax compliance duties that are the responsibility of such REMIC under the Code,
the REMIC Provisions, or other compliance guidance issued by the Internal
Revenue Service or any state or local taxing authority. Among its other duties,
if required by the Code, the REMIC Provisions, or other such guidance, the
Securities Administrator, as agent for the Tax Matters Person, shall provide (i)
to the Treasury or other governmental authority such information as is necessary
for the application of any tax relating to the transfer of the Class R
Certificate to any disqualified person or organization and (ii) to the
Certificateholders such information or reports as are required by the Code or
REMIC Provisions.

            (f) The Trustee, the Securities Administrator, the Servicer, and the
Holders of Certificates shall take any action or cause any REMIC formed under
this Agreement to take any action necessary to create or maintain the status of
such REMIC as a REMIC under the REMIC Provisions and shall assist each other as
necessary to create or maintain such status. None of the Trustee, the Servicer,
the Securities Administrator or the Holder of the Class R Certificate shall take
any action or cause any REMIC formed under this Agreement to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of such REMIC as a REMIC or (ii) result in the imposition of a tax upon
such REMIC (including but not limited to the tax on prohibited transactions as
defined in Code Section 860F(a)(2) and the tax on prohibited contributions set
forth on Section 860G(d) of the Code) (either such event, an "Adverse REMIC
Event") unless the Securities Administrator, the Trustee and the Servicer have
received an Opinion of Counsel (at the expense of the party seeking to take such
action) to the effect that the contemplated action will not endanger such status
or result in the imposition of such a tax. In addition, prior to taking any
action with respect to any REMIC formed under this Agreement or the assets
therein, or causing such REMIC to take any action, which is not expressly
permitted under the terms of this Agreement, any Holder of the Class R
Certificate will consult with the Securities Administrator, the Trustee and the
Servicer, or their respective designees, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to such
REMIC, and no such Person shall take any such action or cause such REMIC to take
any such action as to which the Securities Administrator, the Trustee or the
Servicer has advised it in writing that an Adverse REMIC Event could occur.

            (g) The Holder of the Class R Certificate shall pay when due any and
all taxes imposed on any REMIC formed under this Agreement by federal or state
governmental authorities, but only from amounts, if any, distributable thereon.
To the extent that such REMIC taxes are not paid by the Class R
Certificateholder, the Securities Administrator shall pay any remaining REMIC
taxes out of future amounts otherwise distributable to the Holder of the Class R
Certificate or, if no such amounts are available, out of other amounts held in
the Distribution Account, and shall reduce amounts otherwise payable to Holders
of the REMIC Regular Interests or the Certificates, as the case may be.

            (h) The Securities Administrator, shall, for federal income tax
purposes, maintain or cause to be maintained books and records with respect to
each REMIC formed under this Agreement on a calendar year and on an accrual
basis.

            (i) No additional contributions of assets shall be made to any
REMIC, except as expressly provided in this Agreement with respect to Eligible
Substitute Mortgage Loans.

            (j) None of the Trustee, the Securities Administrator or the
Servicer shall enter into any arrangement by which any REMIC will receive a fee
or other compensation for services.

            (k) On or before April 15 of each calendar year, beginning in 2005,
the Securities Administrator shall deliver to each Rating Agency an Officer's
Certificate stating the Securities Administrator's compliance with the
provisions of this Section 9.01.

            (l) The Securities Administrator shall treat (i) the rights of the
Offered Certificates to receive Cap Carryover Amounts as a right in interest
rate cap contracts written by the Class CE Certificateholders in favor of the
Holders of the Offered Certificates and (ii) the rights of the Class CE
Certificates under the Yield Maintenance Agreement in accordance with the terms
thereof and shall assign such rights for federal tax return and information
reporting a value of zero. The Securities Administrator shall account for such
as property held separate and apart from the regular interests it holds in each
of the REMICs created hereunder. The provisions of this paragraph are intended
to satisfy the requirements of Treasury Regulations Section 1.860G-2(i) for the
treatment of property rights coupled with regular interests to be separately
respected and shall be interpreted consistent with such regulation. On each
Distribution Date, to the extent the Offered Certificates receive interest in
excess of their Certificate Interest Rate, such interest will be treated as
distributed to the Class CE Certificates, together with any amount deposited in
the Reserve Account in respect of the Yield Maintenance Agreement, and then paid
to the respective Classes of Offered Certificates pursuant to the related
interest rate cap agreement.

            Section 9.02 Prohibited Transactions and Activities.

            None of the Depositor, the Servicer, the Securities Administrator or
the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans,
except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii)
the bankruptcy of the Trust Fund, (iii) the termination of any REMIC pursuant to
Article X of this Agreement, (iv) a substitution pursuant to Article II of this
Agreement, (v) a repurchase of Mortgage Loans pursuant to Article II of this
Agreement or (vi) an optional purchase by the Depositor pursuant to Section 3.16
of this Agreement, nor acquire any assets for any REMIC constituting part of the
Trust Fund, nor sell or dispose of any investments in the Distribution Account
for gain, nor accept any contributions to any REMIC constituting part of the
Trust Fund after the Closing Date, unless it has received an Opinion of Counsel
(at the expense of the party causing such sale, disposition, or substitution)
that such disposition, acquisition, substitution, or acceptance will not (a)
affect adversely the status of such REMIC as a REMIC or of the interests therein
other than the Class R Certificate as the regular interests therein, (b) affect
the distribution of interest or principal on the Certificates, (c) result in the
encumbrance of the assets transferred or assigned to the Trust Fund (except
pursuant to the provisions of this Agreement) or (d) cause such REMIC to be
subject to a tax on prohibited transactions or prohibited contributions pursuant
to the REMIC Provisions.

            Section 9.03 Indemnification with Respect to Certain Taxes and Loss
of REMIC Status.

            In the event that any REMIC formed hereunder fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Servicer, the Trustee or the
Securities Administrator of its duties and obligations set forth herein, such
person shall indemnify the Holder of the Class R Certificate against any and all
losses, claims, damages, liabilities or expenses ("Losses") resulting from such
negligence; provided, however, that no such person shall be liable for any such
Losses attributable to the action or inaction of the Trustee, the Depositor or
the Holder of the Class R Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of the Class R Certificate
on which such person has relied. The foregoing shall not be deemed to limit or
restrict the rights and remedies of the Holder of the Class R Certificate now or
hereafter existing at law or in equity. Notwithstanding the foregoing, however,
in no event shall the Servicer have any liability (1) for any action or omission
that is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by the Servicer, the Trustee
or the Securities Administrator of its duties and obligations set forth herein,
and (3) for any special or consequential damages to Certificateholders (in
addition to payment of principal and interest on the Certificates).

            Section 9.04 REO Property.

            (a) Subject to compliance with applicable laws and regulations as
shall at any time be in force, and notwithstanding any other provision of this
Agreement, the Servicer, acting on behalf of the Trust hereunder, shall not
rent, lease, or otherwise earn income on behalf of any REMIC with respect to any
REO Property which might 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 any REMIC of any "income from non-permitted assets"
within the meaning of section 860F(a)(2) of the Code or any "net income from
foreclosure property" which is subject to tax under the REMIC Provisions unless
the Servicer has advised the Trustee in writing to the effect that, under the
REMIC Provisions, such action would not adversely affect the status of any REMIC
as a REMIC and any income generated for such REMIC by the REO Property would not
result in the imposition of a tax upon such REMIC.

            (b) The Servicer shall make reasonable efforts to sell any REO
Property for its fair market value. In any event, however, the Servicer shall
dispose of any REO Property before the close of the third calendar year
beginning after the year of its acquisition by the Trust Fund unless the
Servicer has received a grant of extension from the Internal Revenue Service to
the effect that, under the REMIC Provisions and any relevant proposed
legislation and under applicable state law, any REMIC constituting part of the
Trust Fund may hold REO Property for a longer period without adversely affecting
its REMIC status or causing the imposition of a Federal or state tax upon any
REMIC constituting part of the Trust Fund. If the Servicer has received such an
extension, then the Servicer shall continue to attempt to sell the REO Property
for its fair market value as determined in good faith by the Servicer for such
longer period as such extension permits (the "Extended Period"). If the Servicer
has not received such an extension and the Servicer is unable to sell the REO
Property by September 30th of the third year after its acquisition by the Trust
Fund or if the Servicer has received such an extension, and the Servicer is
unable to sell the REO Property within the period ending three months before the
close of the Extended Period, the Servicer shall, before the end of the
applicable period, (i) purchase such REO Property at a price equal to the REO
Property's fair market value as determined in good faith by the Servicer or (ii)
auction the REO Property to the highest bidder (which may be the Servicer) in an
auction reasonably designed to produce a fair price prior to the expiration of
the applicable period.

            Section 9.05 Grantor Trust Administration.

            The parties intend that the portions of the Trust Fund consisting of
the right of the Class P Certificates to receive Prepayment Charges, the right
of the Offered Certificates to receive Cap Carryover Amounts, the Reserve
Account and the right of the Class CE Certificates to receive Yield Maintenance
Agreement Payments subject to the obligation of the Class CE Certificates to pay
Cap Carryover Amounts, shall be treated as a "grantor trust" under the Code, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Securities Administrator shall furnish or
cause to be furnished (i) to the Holders of the Offered Certificates and (ii) to
the Holder of the Class CE Certificates and shall file or cause to be filed with
the Internal Revenue Service together with Form 1041 or such other form as may
be applicable, their allocable shares of income and expenses with respect to the
property held by the Grantor Trust, at the time or times and in the manner
required by the Code.

                                    ARTICLE X

                                   TERMINATION

            Section 10.01 Termination.

            (a) The respective obligations and responsibilities of the Servicer,
the Depositor, the Trustee, the Securities Administrator and the Certificate
Registrar created hereby (other than the obligation of the Trustee to make
certain payments to Certificateholders after the final Distribution Date and the
obligation of the Servicer to send certain notices as hereinafter set forth)
shall terminate upon notice to the Trustee upon the earliest of (i) the
Distribution Date on which the Principal Balance of each Class of Certificates
has been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, and (iii) the optional purchase by the
Depositor of the Mortgage Loans as described below. Notwithstanding the
foregoing, in no event shall the trust created hereby continue beyond the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James, living on the date hereof.

            The Depositor may, at its option, terminate the Trust Fund and
retire the Certificates on the next succeeding Distribution Date upon which the
aggregate current Pool Balance is less than 10% of the aggregate Pool Balance of
the Mortgage Loans as of the Cut-off Date by purchasing all of the outstanding
(i) Mortgage Loans in the Trust Fund at a price equal to the sum of the
outstanding Principal Balance of the Mortgage Loans and except to the extent
previously advanced by the Servicer, accrued and unpaid interest thereon at the
weighted average of the Mortgage Interest Rates through the end of the
Collection Period preceding the final Distribution Date plus unreimbursed
Servicing Advances, Advances and any unpaid Servicing Fees allocable to such
Mortgage Loans and (ii) REO Properties in the Trust Fund at a price equal to
their fair market value as determined in good faith by the Servicer (the
"Termination Price"). If the Depositor or an affiliate of the Depositor is
subject to regulation by the OCC, the FDIC, the Federal Reserve or the Office of
Thrift Supervision, however, the option may not be exercised unless the
aggregate fair market value of the Mortgage Loans and REO Properties is greater
than or equal to the Termination Price. Notwithstanding the foregoing, the
Depositor may exercise this optional purchase right unless any Reimbursement
Amount owed to the Trust pursuant to Section 2.03 hereof has been paid.

            In connection with any such purchase pursuant to the preceding
paragraph, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account all amounts then on deposit in the Collection Account (less
amounts permitted to be withdrawn by the Servicer pursuant to Section 3.07),
which deposit shall be deemed to have occurred immediately following such
purchase.

            Any such purchase shall be accomplished by delivery on the
Determination Date before such Distribution Date of the Termination Price to the
Trustee for deposit into the Distribution Account as part of Available Funds.

            (b) Notice of any termination, specifying the Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee upon the Trustee receiving notice of such date from the Depositor by
letter to the Certificateholders and the Securities Administrator mailed not
earlier than the 15th day of the month preceding the month of such final
distribution and not later than the 15th day of the month of such final
distribution specifying (1) the Distribution Date upon which final distribution
of the Certificates will be made upon presentation and surrender of such
Certificates at the office or agency of the Trustee therein designated, (2) the
amount of any such final distribution and (3) that the Record Date otherwise
applicable to such Distribution Date is not applicable, distributions being made
only upon presentation and surrender of the Certificates at the office or agency
of the Trustee therein specified. Not less than five (5) Business Days prior to
such Determination Date relating to such Distribution Date, the Trustee shall
notify the Depositor of the amount of any unpaid Reimbursement Amount owed to
the Trust.

            (c) Upon presentation and surrender of the Certificates, the Trustee
shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Sections 4.01 and 4.02 for
such Distribution Date.

            (d) In the event that all Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Servicer shall give a second written
notice to the remaining Certificateholders, to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
nine months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Class R Certificateholder shall be entitled to
all unclaimed funds and other assets which remain subject hereto (except with
respect to the Class B, Class CE and Class P Certificates) and the Trustee upon
transfer of such funds shall be discharged of any responsibility for such funds,
and all other Certificateholders shall look to the Class R Certificateholder for
payment.

            Section 10.02 Additional Termination Requirements.

            (a) In the event that the Depositor exercises its purchase option as
provided in Section 10.01, the Trust shall be terminated in accordance with the
following additional requirements, unless the Trustee shall have been furnished
with an Opinion of Counsel to the effect that the failure of the Trust to comply
with the requirements of this Section will not (i) result in the imposition of
taxes on "prohibited transactions" of the Trust as defined in Section 860F of
the Code or (ii) cause any REMIC constituting part of the Trust Fund to fail to
qualify as a REMIC at any time that any Certificates are outstanding:

            (i) The Trustee shall designate a date within 90 days prior to the

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

            Section 11.01 Amendment.

            This Agreement may be amended from time to time by the Depositor,
the Servicer, the Securities Administrator and the Trustee; and without the
consent of the Certificateholders, (i) to cure any ambiguity or mistake, (ii) to
correct or supplement any provision herein that may be inconsistent with any
other provision herein or in the Prospectus Supplement, (iii) to modify,
eliminate or add to any of its provisions to such extent as shall be necessary
to maintain the qualification of the Trust Fund (or one or more segregated pools
of assets therein) as a REMIC at all times that any Certificates are outstanding
or to avoid or minimize the risk of the imposition of any tax on the Trust Fund
pursuant to the Code that would be a claim against the Trust Fund, provided that
the Trustee has received an opinion of counsel to the effect that such action is
necessary or desirable to maintain such qualification or to avoid or minimize
the risk of the imposition of any such tax and such action will not, as
evidenced by such opinion of counsel, adversely affect in any material respect
the interests of any Certificateholder, (iv) to change the timing and/or nature
of deposits into the Collection Account or Distribution Account, provided that
such change will not, as evidenced by an opinion of counsel, adversely affect in
any material respect the interests of any Certificateholder, (v) to add to,
modify or eliminate any provisions therein restricting transfers of the Class R
Certificates to certain disqualified organizations, (vi) to make certain
provisions with respect to the denominations of, and the manner of payments on,
certain Classes of Certificates initially retained by the Depositor or an
affiliate, (vii) to provide for the rights of a net interest margin securities
insurer, if any, or (viii) to make any other provisions with respect to matters
or questions arising under such Agreement that are not inconsistent with the
provisions thereof, provided that such action will not, as evidenced by an
opinion of counsel, adversely affect in any material respect the interests of
the Certificateholders; provided, however, that such action described in clause
(iv) or (viii) will not be considered to adversely affect in any material
respect the interest of Certificateholders and no opinion of counsel to that
effect will be required if each Rating Agency rating the Certificates states in
writing that such action would not result in the downgrading or withdrawal of
the ratings then assigned to the Securities.

            In addition, this Agreement may be amended from time to time by the
Depositor, the Servicer, the Securities Administrator and the Trustee, with the
consent of the Majority Certificateholders for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders of
Certificates; provided, however, that no such amendment or waiver shall (x)
reduce in any manner the amount of, or delay the timing of, payments on the
Certificates which are required to be made on any Certificate without the
consent of the Holder of such Certificate, (y) adversely affect in any material
respect the interests of the Holders of any Class of Certificates in a manner
other than as described in clause (x) above, without the consent of the Holders
of Certificates of such Class evidencing at least a majority of the Percentage
Interest in such Class, or (z) reduce the percentage of Voting Interests
required by clause (y) above without the consent of the Holders of all
Certificates of such Class then outstanding. Upon approval of an amendment, a
copy of such amendment shall be sent to the Rating Agencies. Prior to the
execution of any amendment to this Agreement, the Trustee will not consent to
any amendment of the applicable Agreement unless it shall first have received an
opinion stating that the execution of such amendment is authorized or permitted
by this Agreement. The Trustee may, but shall not be obligated to, enter into
any such amendment which affects the Trustee's own rights, duties or immunities
under this Agreement.

            Notwithstanding any provision of this Agreement to the contrary, the
Trustee shall not consent to any amendment to this Agreement unless it shall
have first received an Opinion of Counsel, delivered by (and at the expense of)
the Person seeking such Amendment, to the effect that such amendment will not
result in the imposition of a tax on any REMIC constituting part of the Trust
Fund pursuant to the REMIC Provisions or cause any REMIC constituting part of
the Trust Fund to fail to qualify as a REMIC at any time that any Certificates
are outstanding and that the amendment is being made in accordance with the
terms hereof.

            Promptly after the execution of any such amendment the Trustee shall
furnish, at the expense of the Person that requested the amendment if such
Person is the Servicer (but in no event at the expense of the Trustee),
otherwise at the expense of the Trust, a copy of such amendment and the Opinion
of Counsel referred to in the immediately preceding paragraph to the Servicer
and each Rating Agency.

            It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment; instead it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

            Section 11.02 Recordation of Agreement; Counterparts.

            To the extent permitted by applicable law, this Agreement is subject
to recordation in all appropriate public offices for real property records in
all the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Servicer at the expense of the Trust, but only upon direction of
Certificateholders, accompanied by an Opinion of Counsel to the effect that such
recordation materially and beneficially affects the interests of the
Certificateholders.

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

            Section 11.03 Limitation on Rights of Certificateholders.

            The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust, or (iii) otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

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

            No Certificateholder shall have any right by virtue of any provision
of this Agreement to institute any suit, action or proceeding in equity or at
law upon or under or with respect to this Agreement, unless such Holder
previously shall have given to the Trustee a written notice of default and of
the continuance thereof, as herein provided, and unless also the Holders of
Certificates entitled to at least 25% of the Voting Interests shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity, shall have neglected
or refused to institute any such action, suit or proceeding. It is understood
and intended, and expressly covenanted by each Certificateholder with every
other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatever by virtue of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, which priority or
preference is not otherwise provided for herein, or to enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all Certificateholders. For the protection and enforcement
of the provisions of this Section 11.03 each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

            Section 11.04 Governing Law; Jurisdiction.

            This Agreement shall be construed in accordance with the laws of the
State of New York, and the obligations, rights and remedies of the parties
hereunder shall be determined in accordance with such laws. With respect to any
claim arising out of this Agreement, each party irrevocably submits to the
exclusive jurisdiction of the courts of the State of New York and the United
States District Court located in the Borough of Manhattan in The City of New
York, and each party irrevocably waives any objection which it may have at any
time to the laying of venue of any suit, action or proceeding arising out of or
relating hereto brought in any such courts, irrevocably waives any claim that
any such suit, action or proceeding brought in any such court has been brought
in any inconvenient forum and further irrevocably waives the right to object,
with respect to such claim, suit, action or proceeding brought in any such
court, that such court does not have jurisdiction over such party, provided that
service of process has been made by any lawful means.

Such instrument or instruments (and the action embodied therein and evidenced

acquired in respect of any Mortgage Loan at a price determined as provided in

less of the Cut-off Date Aggregate Principal Balance.

acquired in respect of any Mortgage Loan at a price determined as provided in

held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate
Principal Balance of the Mortgage Loans at the time of purchase being 10% or
less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to the Holders of Class
M-2 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class M-2 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class M-2
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

            The Certificate Interest Rate for the Class M-2 Certificates for
each Distribution Date will be the least of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class M-2 Certificate Margin, (ii) the
Pool Maximum Rate Cap and (iii) the Pool Cap. Interest will accrue on the Class
M-2 Certificates during each Interest Accrual Period at the Certificate Interest
Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as Wells Fargo Asset Securities Corporation, Home Equity Asset Backed
Certificates of the Series specified on the face hereof (herein called the
"Certificates") and representing a Percentage Interest in the Class M-2
Certificates.

            The Class M-2 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            This certificate is subordinated in right of payment to the Class A
Certificates and Class M-1 Certificates as described in the Pooling and
Servicing Agreement referred to herein.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer, the Securities
Administrator and the Trustee with the consent of the Holders of Certificates
entitled to the Voting Interests identified in the agreement. Any such consent
by the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee, the
Securities Administrator and the Certificate Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee, the Securities
Administrator and the Certificate Registrar and any agent of the Depositor, the
Servicer, the Trustee, the Securities Administrator or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Servicer, the Trustee,
the Certificate Registrar nor any such agent shall be affected by notice to the
contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate
Principal Balance of the Mortgage Loans at the time of purchase being 10% or
less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee, the
Securities Administrator and the Certificate Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
effective registration or qualification under applicable state securities laws,
or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee, the Securities Administrator or the Certificate
Registrar, in their respective capacities as such. None of the Depositor, the
Certificate Registrar or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any Servicer against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

            No transfer of a Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee, the Securities
Administrator and the Certificate Registrar and any agent of the Depositor, the
Servicer, the Trustee, the Securities Administrator or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Servicer, the Trustee,
the Certificate Registrar nor any such agent shall be affected by notice to the
contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate
Principal Balance of the Mortgage Loans at the time of purchase being 10% or
less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assume no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

of which is set forth hereafter. To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the

            All distributions to the Holder of this Certificate under the

Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

            This Certificate is one of a duly authorized issue of Certificates
designated as Wells Fargo Asset Securities Corporation, Home Equity Asset Backed
Certificates of the Series specified on the face hereof (herein called the
"Certificates") and representing the Percentage Interest specified on the face
hereof.

            The Class P Certificates are limited in right of payment to
Prepayment Charges received on the Mortgage Loans, Originator Prepayment Charge
Payment Amounts and Servicer Prepayment Charge Payment Amounts, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer, the Securities
Administrator and the Trustee with the consent of the Holders of Certificates
entitled to the Voting Interests identified in the agreement. Any such consent
by the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee, the
Securities Administrator and the Certificate Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
effective registration or qualification under applicable state securities laws,
or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee, the Securities Administrator or the Certificate
Registrar, in their respective capacities as such. None of the Depositor, the
Certificate Registrar or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any Servicer against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

            No transfer of a Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee, the Securities
Administrator and the Certificate Registrar and any agent of the Depositor, the
Servicer, the Trustee, the Securities Administrator or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Servicer, the Trustee,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate
Principal Balance of the Mortgage Loans at the time of purchase being 10% or
less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the

preceding the month in which the related Distribution Date occurs (the "Record

pursuant to the Agreement.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class R

the final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose as provided in the Agreement.

            This Certificate is one of a duly authorized issue of Certificates
designated as Wells Fargo Asset Securities Corporation, Home Equity Asset Backed
Certificates of the Series specified on the face hereof (herein called the
"Certificates") and representing the Percentage Interest specified on the face
hereof.

            The Class R Certificate is limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer, the Securities
Administrator and the Trustee with the consent of the Holders of Certificates
entitled to the Voting Interests identified in the agreement. Any such consent
by the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee, the
Securities Administrator and the Certificate Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations evidencing the same aggregate Percentage Interest will be issued
to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
effective registration or qualification under applicable state securities laws,
or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee, the Securities Administrator or the Certificate
Registrar, in their respective capacities as such. None of the Depositor, the
Certificate Registrar or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any Servicer against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

            No transfer of this Certificate or any interest therein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes to have consented to the provisions of Section 5.02 of
the Agreement and to any amendment of the Agreement deemed necessary by counsel
of the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause the Trust
to cease to qualify as two separate REMICs or cause the imposition of a tax upon
the Trust.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee, the Securities
Administrator and the Certificate Registrar and any agent of the Depositor, the
Servicer, the Trustee, the Securities Administrator or the Certificate Registrar
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and none of the Depositor, the Servicer, the Trustee,
the Certificate Registrar nor any such agent shall be affected by notice to the
contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate
Principal Balance of the Mortgage Loans at the time of purchase being 10% or
less of the Cut-off Date Aggregate Principal Balance.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

STATE OF                )

COUNTY OF               )

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

            1. The undersigned is [an officer of] ____________________, the
proposed Transferee of an Ownership Interest in the Class R Certificates (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Certificates, among Wells Fargo
Asset Securities Corporation, as depositor, Wells Fargo Home Mortgage, Inc., as
servicer, Wells Fargo Bank, National Association, as securities administrator,
and [_______________________________], as trustee (the "Trustee"). Capitalized
terms used, but not defined herein shall have the meanings ascribed to such
terms in the Agreement. The Transferee has authorized the undersigned to make
this affidavit on behalf of the Transferee.

            2. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificates either (i) for its own account or (ii) as
nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

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

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

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

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

            7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Certificate.

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

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

            10. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

            11. That the Transferee will not cause income from the Class R
Certificate to be attributable to a foreign permanent establishment or fixed
base, within the meaning of an applicable income tax treaty, of the Transferee
or any other person.

            12. That, if the Transferee is purchasing the Class R Certificate in
a transfer intended to meet the safe harbor provisions of Treasury Regulations
Sections 1.860E-1(c), the Transferee has executed and attached Attachment A
hereto.

            13. The Transferee is not an employee benefit plan that is subject
to ERISA or a plan that is subject to Section 4975 of the Code or a plan or
arrangement subject to any materially similar provisions of applicable federal,
state or local law, nor are we acting on behalf of such a plan.

liabilities over (b) the present value of the anticipated savings associated
with holding such Certificate, in each case calculated in accordance with U.S.
Treasury Regulations Sections 1.860E-1(c)(7) and (8), computing present values
using a discount rate equal to the short-term Federal rate prescribed by Section
1274(d) of the Code and the compounding period used by the Transferee.

            OR

|_|  The transfer of the Class R Certificate complies with U.S. Treasury
Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly:

            (i) the Transferee is an "eligible corporation," as defined in U.S.
      Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from

            (ii) at the time of the transfer, and at the close of the
      Transferee's two fiscal years preceding the year of the transfer, the

      any obligation of a person related to the Transferee within the meaning of
      U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100
      million and net assets in excess of $10 million;

      (including, but not limited to, borrowing and investment rates, prepayment
      and loss assumptions, expense and reinvestment assumptions, tax rates and
      other factors specific to the Transferee) that it has determined in good
      faith; and

      Transferee, the Transferee will require its transferee to complete a
      representation in the form of this Attachment A as a condition of the

from time to time as permitted hereby, this "Indenture"), is between WELLS FARGO
HOME EQUITY ASSET-BACKED SECURITIES 20 -[___] TRUST, a Delaware statutory trust
(together with its permitted successors and assigns, the "Issuer") and
[__________________], a [_________] as indenture trustee (together with its
permitted successors in the trusts hereunder, the "Indenture Trustee").

                              Preliminary Statement

      The Issuer has duly authorized the execution and delivery of this
Indenture to provide for its Asset Backed Notes, Series 20 - , Class A (the
"Notes"), issuable as provided in this Indenture. All covenants and agreements
made by the Issuer herein are for the benefit and security of the Holders of the
Notes. The Issuer is entering into this Indenture, and the Indenture Trustee is
accepting the trusts created hereby, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged.

      All things necessary to make this Indenture a valid agreement of the
Issuer in accordance with its terms have been done.

                                 Granting Clause

      The Issuer hereby Grants to the Indenture Trustee, for the exclusive
benefit of the Holders of the Notes, all of the Issuer's right, title and
interest in and to (a) the Mortgage Loans listed in Schedule I to this Indenture
(including property that secures a Mortgage Loan that becomes an REO Property),
including the related Mortgage Files delivered or to be delivered to the
Custodian, on behalf of the Indenture Trustee, pursuant to the Mortgage Loan
Purchase Agreement, all payments of principal received, collected or otherwise
recovered after the Cut-off Date for each Mortgage Loan, all payments of
interest accruing on each Mortgage Loan after the Cut-off Date therefor whenever

any Qualified Replacement Mortgage Loan, (b) the Servicing Agreement, (c) the
Mortgage Loan Purchase Agreement, (d) the Insurance Policies, (e) all cash,
instruments or other property held or required to be deposited in the Collection
Account and the Note Account, including all investments made with funds in such

income shall belong to and be for the account of the Servicer), and (f) all
proceeds of the conversion, voluntary or involuntary, of any of the foregoing
into cash or other liquid assets, including, without limitation, all insurance
proceeds and condemnation awards. Such Grants are made, however, in trust, to
secure the Notes equally and ratably without prejudice, priority or distinction
between any Note and any other Note by reason of difference in time of issuance
or otherwise, to secure (x) the payment of all amounts due on the Notes in
accordance with their terms, (y) the payment of all other sums payable under
this Indenture and (z) compliance with the provisions of this Indenture, all as
provided in this Indenture. All terms used in the foregoing granting clauses

                                   DEFINITIONS

      Section 1.01. General Definitions.

      Except as otherwise specified or as the context may otherwise require, the
following terms have the respective meanings set forth below for all purposes of
this Indenture, and the definitions of such terms are applicable to the singular
as well as to the plural forms of such terms and to the masculine as well as to
the feminine genders of such terms. Whenever reference is made herein to an
Event of Default or a Default known to the Indenture Trustee or of which the
Indenture Trustee has notice or knowledge, such reference shall be construed to
refer only to an Event of Default or Default of which the Indenture Trustee is
deemed to have notice or knowledge pursuant to Section 6.01(d). All other terms
used herein that are defined in the Trust Indenture Act (as hereinafter
defined), either directly or by reference therein, have the meanings assigned to
them therein.

the payment, if any, in reduction of principal made on such Notes on such
preceding Distribution Date). All calculations of interest on the Notes will be
computed on the basis of twelve thirty-day months and a year of 360 days.

For the purposes of this definition, "control" when used with respect to any

securities, by contract, relation to individuals or otherwise, and the terms
"controlling" and "controlled" have meanings correlative to the foregoing.

Distribution Date, the aggregate of the Principal Balances of the Mortgage Loans
as of the related Determination Date (or other specified date).

      "Assignments": The original instrument of assignment of a Mortgage,
including any interim assignments, from the originator or any other holder of
any Mortgage Loan to the Indenture Trustee (that in each case may, to the extent
permitted by the laws of the state in which the related Mortgaged Property is

Mortgage Notes as well and that may also be an instrument of assignment running
directly from the mortgagee of record under the related Mortgage to the
Indenture Trustee).

      "Authenticating Agent": The Person, if any, appointed as Authenticating
Agent by the Issuer pursuant to Section 6.14, until any successor Authenticating
Agent for the Notes is named, and thereafter "Authenticating Agent" shall mean
such successor. The Authenticating Agent shall be the Indenture Trustee. Any
Authenticating Agent other than the Indenture Trustee shall sign an instrument

final and nonappealable order of a United States bankruptcy court of competent
jurisdiction imposing a stay pursuant to Section 362 of the Bankruptcy Code and
that would otherwise have been included in Available Funds on such Distribution
Date and (B) received by the Indenture Trustee that are recoverable and sought
to be recovered from the Issuer as a voidable preference by a trustee in
bankruptcy pursuant to the Bankruptcy Code in accordance with a final
nonappealable order of a court of competent jurisdiction:

            (a) all scheduled payments of interest received with respect to the
      Mortgage Loans and due during the related Collection Period and all other

theft of any Note, and (2) there is delivered to the Note Registrar such
security or indemnity as may be required by the Note Registrar to save each of
the Issuer and the Note Registrar harmless, then, in the absence of notice to
the Issuer or the Note Registrar that such Note has been acquired by a bona fide
purchaser, the Owner Trustee on behalf of the Issuer shall execute and upon its
request the Note Registrar shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Note, a new Note or Notes
of the same tenor and aggregate initial principal amount bearing a number not
contemporaneously outstanding. If, after the delivery of such new Note, a bona
fide purchaser of the original Note in lieu of which such new Note was issued
presents for payment such original Note, the Issuer and the Note Registrar shall
be entitled to recover such new Note from the person to whom it was delivered or
any person taking therefrom, except a bona fide purchaser, and shall be entitled
to recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expenses incurred by the Issuer or the Note Registrar in
connection therewith. If any such mutilated, destroyed, lost or stolen Note

become subject to redemption in full, instead of issuing a new Note, the Issuer
may pay such Note without surrender thereof, except that any mutilated Note
shall be surrendered.

Note Registrar may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the fees and expenses of the Indenture Trustee or
the Note Registrar) connected therewith.

      Every new Note issued pursuant to this Section in lieu of any destroyed,
lost or stolen Note shall constitute an original additional contractual
obligation of the Issuer, whether or not the destroyed, lost or stolen Note
shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Notes duly issued hereunder.

      The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes.

      Section 2.08. Payments of Principal and Interest.

      (a) Payments on Notes issued as Book-Entry Notes will be made by or on
behalf of the Indenture Trustee to the Clearing Agency or its nominee. Any
installment of interest or principal payable on any Definitive Notes that is
punctually paid or duly provided for by the Issuer on the applicable
Distribution Date shall be paid to the Person in whose name such Note (or one or
more Predecessor Notes) is registered at the close of business on the Record
Date for such Distribution Date by either (i) check mailed to such Person's
address as it appears in the Note

                                      -23-
<PAGE>

Register on such Record Date, or (ii) by wire transfer of immediately available
funds to the account of a Noteholder, if such Noteholder (A) is the registered
holder of Definitive Notes having an initial principal amount of at least
$1,000,000 and (B) has provided the Indenture Trustee with wiring instructions
in writing by five Business Days prior to the related Record Date or has
provided the Indenture Trustee with such instructions for any previous
Distribution Date, except for the final installment of principal payable with
respect to such Note (or the Redemption Price for any Note called for
redemption, if such redemption will result in payment of the then entire unpaid
principal amount of such Note), which shall be payable as provided in subsection
(b) below of this Section 2.08. A fee may be charged by the Indenture Trustee to
a Noteholder of Definitive Notes for any payment made by wire transfer. Any
installment of interest or principal not punctually paid or duly provided for
shall be payable as soon as funds are available to the Indenture Trustee for
payment thereof, or if Section 5.07 applies, pursuant to Section 5.07.

      (b) All reductions in the principal amount of a Note (or one or more
Predecessor Notes) effected by payments of installments of principal made on any
Distribution Date shall be binding upon all Holders of such Note and of any Note
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, whether or not such payment is noted on such Note. The final
installment of principal of each Note (including the Redemption Price of any
Note called for optional redemption, if such optional redemption will result in
payment of the entire unpaid principal amount of such Note) shall be payable
only upon presentation and surrender thereof on or after the Distribution Date
therefor at the Indenture Trustee's presenting office located within the United
States of America pursuant to Section 3.02.

      Whenever the Indenture Trustee expects that the entire remaining unpaid
principal amount of any Note will become due and payable on the next
Distribution Date other than pursuant to a redemption pursuant to Article X, it
shall, no later than two days prior to such Distribution Date, telecopy or hand
deliver to each Person in whose name a Note to be so retired is registered at
the close of business on such otherwise applicable Record Date a notice to the
effect that:

            (i) the Indenture Trustee expects that funds sufficient to pay such
      final installment will be available in the Note Account on such
      Distribution Date; and

            (ii) if such funds are available, (A) such final installment will be
      payable on such Distribution Date, but only upon presentation and
      surrender of such Note at the office or agency of the Note Registrar
      maintained for such purpose pursuant to Section 3.02 (the address of which
      shall be set forth in such notice) and (B) no interest shall accrue on
      such Note after such Distribution Date.

      Notices in connection with redemptions of Notes shall be mailed to
Noteholders in accordance with Section 10.02.

      (c) Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to unpaid principal and
interest that were carried by such other Note. Any checks

                                      -24-
<PAGE>

mailed pursuant to subsection (a) of this Section 2.08 and returned undelivered
shall be held in accordance with Section 3.03.

      (d) Each Distribution Date Statement, prepared by the Indenture Trustee
based on the Remittance Report delivered to the Indenture Trustee pursuant to
the Servicing Agreement, shall be made available via the Depositor's internet
website to the Rating Agencies, the Owner Trustee and each Noteholder as the
statement required pursuant to Section 8.06. Noteholders that are unable to use
the above distribution options are entitled to have a paper copy mailed to them
via first class mail by calling (301) 846-8881 and indicating such. Neither the
Indenture Trustee nor the Paying Agent shall have any responsibility to
recalculate, verify or recompute information contained in any such tape,
electronic data file or disk or any such Remittance Report except to the extent
necessary to satisfy all obligations under this Section 2.08(d).

      Within 90 days after the end of each calendar year, the Indenture Trustee
will be required to furnish to each person who at any time during the calendar
year was a Noteholder, if requested in writing by such person, a statement
containing the information set forth in subclauses (i) and (ii) in the
definition of "Distribution Date Statement," aggregated for such calendar year
or the applicable portion thereof during which such person was a Noteholder.
Such obligation will be deemed to have been satisfied to the extent that
substantially comparable information is provided pursuant to any requirements of
the Code as are from time to time in force.

      Section 2.09. Persons Deemed Owner.

      Prior to due presentment for registration of transfer of any Note, the
Issuer, the Indenture Trustee, any Paying Agent and any other agent of the
Issuer or the Indenture Trustee may treat the Person in whose name any Note is
registered as the owner of such Note (a) on the applicable Record Date for the
purpose of receiving payments of the principal of and interest on such Note and
(b) on any other date for all other purposes whatsoever, and neither the Issuer,
the Indenture Trustee, any Paying Agent nor any other agent of the Issuer or the
Indenture Trustee shall be affected by notice to the contrary.

      Section 2.10. Cancellation.

      All Notes surrendered for payment, registration of transfer, exchange or
redemption shall, if surrendered to any Person other than the Note Registrar, be
delivered to the Note Registrar and shall be promptly canceled by it. The Issuer
may at any time deliver to the Note Registrar for cancellation any Note
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Notes so delivered shall be promptly
canceled by the Note Registrar. No Notes shall be authenticated in lieu of or in
exchange for any Notes canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Notes held by the Note Registrar shall
be held by the Note Registrar in accordance with its standard retention policy,
unless the Issuer shall direct by an Issuer Order that they be destroyed or
returned to it.

      Section 2.11. Authentication and Delivery of Notes.

      The Notes shall be executed by an Authorized Officer of the Owner Trustee
on behalf of the Issuer and delivered to the Authenticating Agent for
authentication, and thereupon the same

                                      -25-

officer's certificates of the Issuer, the Owner Trustee, the Servicer, the
Securities Administrator and the Indenture Trustee, without independent
confirmation or verification with respect to factual matters relevant to such

no opinion as to (A) the existence of, or the priority of the security interest
created by the Indenture against, any liens or other interests that arise by
operation of law and that do not require any filing or similar action in order
to take priority over a perfected security interest or (B) the priority of the
security interest created by this Indenture with respect to any claim or lien in
favor of the United States or any agency or instrumentality thereof (including
federal tax liens and liens arising under Title IV of the Employee Retirement
Income Security Act of 1974).

      issuance of the Notes will not result in any breach of any of the terms,
      conditions or provisions of, or constitute a default under, the Issuer's
      Certificate of Trust or any indenture, mortgage, deed of trust or other
      agreement or instrument to which the Issuer is a party or by which it is
      bound, or any order of any court or administrative agency entered in any
      proceeding to which the Issuer is a party or by which it may be bound or
      to which it may be subject, and that all conditions precedent provided in
      this Indenture relating to the authentication and delivery of the Notes
      have been complied with;

            (ii) the Issuer is the owner of each Mortgage Loan, free and clear
      of any lien, security interest or charge, has not assigned any interest or
      participation in any such Mortgage Loan (or, if any such interest or
      participation has been assigned, it has been released) and has the right
      to Grant each such Mortgage Loan to the Indenture Trustee;

            (iii) the information set forth in the Mortgage Loan Schedule
      attached as Schedule I to this Indenture is correct;

            (iv) the Issuer has Granted to the Indenture Trustee all of its

      Section 2.12. Book-Entry Note.

      The Notes will be issued initially as one or more certificates in the name
of the Cede & Co., as nominee for the Clearing Agency maintaining book-entry
records with respect to ownership and transfer of such Notes, and held by the
Clearing Agency or, pursuant to the Clearing Agency's instructions on behalf of
the Clearing Agency, deposited with the Indenture Trustee, and registration of
the Notes may not be transferred by the Note Registrar except upon Book-Entry
Termination. In such case, the Note Registrar shall deal with the Clearing
Agency as representatives of the Beneficial Owners of such Notes for purposes of
exercising the rights of Noteholders hereunder. Each payment of principal of and
interest on a Book-Entry Note shall be paid to the Clearing Agency, which shall
credit the amount of such payments to the accounts of its Clearing Agency
Participants in accordance with its normal procedures. Each Clearing Agency
Participant shall be responsible for disbursing such payments to the Beneficial
Owners of the Book-Entry Notes that it represents and to each indirect
participating brokerage firm (a "brokerage firm" or "indirect participating
firm") for which it acts as agent. Each brokerage firm shall be responsible for
disbursing funds to the Beneficial Owners of the Book-Entry Notes that it
represents. All such credits and disbursements are to be made by the Clearing
Agency and the Clearing Agency Participants in accordance with the provisions of
the Notes. None of the Indenture Trustee, the Note Registrar, if any, the
Issuer, or any Paying Agent shall have any responsibility therefor except as
otherwise provided by applicable law. Requests and directions from, and votes
of, such representatives shall not be deemed to be inconsistent if they are made
with respect to different Beneficial Owners.

      Section 2.13. Termination of Book Entry System.

      (a) The book-entry system through the Clearing Agency with respect to the
Book-Entry Notes may be terminated when the Clearing Agency advises the
Indenture Trustee that the Clearing Agency is no longer willing or able to
discharge properly its responsibilities as nominee and depositary with respect
to the Notes and the Indenture Trustee is unable to locate a qualified successor
clearing agency satisfactory to the Issuer:

                                      -27-
<PAGE>

      (b) Upon the occurrence of the event described in subsection (a) above,
the Indenture Trustee shall use all reasonable efforts to notify all Beneficial
Owners, through the Clearing Agency, of the occurrence of such event and of the
availability of Definitive Notes to Beneficial Owners requesting the same, in an
aggregate Principal Balance representing the interest of each, making such
adjustments and allowances as it may find necessary or appropriate as to accrued
interest and previous calls for redemption. Definitive Notes shall be issued
only upon surrender to the Indenture Trustee of the global Note by the Clearing
Agency, accompanied by registration instructions for the Definitive Notes.
Neither the Issuer nor the Indenture Trustee shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon issuance of the Definitive
Notes, all references herein to obligations imposed upon or to be performed by
the Clearing Agency shall cease to be applicable and the provisions relating to
Definitive Notes shall be applicable.

                                   ARTICLE III

                                    COVENANTS

      Section 3.01. Payment of Notes.

      The Issuer will pay or cause to be duly and punctually paid the principal
of, and interest on, the Notes in accordance with the terms of the Notes and
this Indenture. The Notes shall be non-recourse obligations of the Issuer and
shall be limited in right of payment to amounts available from the Trust Fund as
provided in this Indenture and the Issuer shall not otherwise be liable for
payments on the Notes. No person shall be personally liable for any amounts
payable under the Notes. If any other provision of this Indenture conflicts or
is deemed to conflict with the provisions of this Section 3.01, the provisions
of this Section 3.01 shall control.

      Section 3.02. Maintenance of Office or Agency.

      The Issuer will cause the Note Registrar to maintain its corporate trust
office at a location where Notes may be surrendered for registration of transfer
or exchange, and where notices and demands to or upon the Issuer in respect of
the Notes and this Indenture may be served.

      The Issuer may also from time to time at its own expense designate one or
more other offices or agencies within the United States of America where the
Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided, however, any designation of an
office or agency for payment of Notes shall be subject to Section 3.03. The
Issuer will give prompt written notice to the Indenture Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

      Section 3.03. Money for Note Payments to Be Held In Trust.

      All payments of amounts due and payable with respect to any Notes that are
to be made from amounts withdrawn from the Note Account pursuant to Section
8.02(c) or Section 5.07 shall be made on behalf of the Issuer by the Paying
Agent, and no amounts so withdrawn from the Note Account for payments of Notes
shall be paid over to the Issuer under any circumstances except as provided in
this Section 3.03 or in Section 5.07 or Section 8.02.

                                      -28-
<PAGE>

      With respect to Definitive Notes, if the Issuer shall have a Paying Agent
that is not also the Note Registrar, such Note Registrar shall furnish, no later
than the fifth calendar day after each Record Date, a list, in such form as such
Paying Agent may reasonably require, of the names and addresses of the Holders
of Notes and of the number of Individual Notes held by each such Holder.

      Whenever the Issuer shall have a Paying Agent other than the Indenture
Trustee, it will, on or before the Business Day next preceding each Distribution
Date direct the Indenture Trustee to deposit with such Paying Agent an aggregate
sum sufficient to pay the amounts then becoming due (to the extent funds are
then available for such purpose in the Note Account), such sum to be held in
trust for the benefit of the Persons entitled thereto. Any moneys deposited with
a Paying Agent in excess of an amount sufficient to pay the amounts then
becoming due on the Notes with respect to which such deposit was made shall,
upon Issuer Order, be paid over by such Paying Agent to the Indenture Trustee
for application in accordance with Article VIII.

      Any Paying Agent other than the Indenture Trustee may be appointed by
Issuer Order and at the expense of the Issuer. The Issuer shall not appoint any
Paying Agent (other than the Indenture Trustee) that is not, at the time of such
appointment, a depository institution or trust company whose obligations would
be Permitted Investments pursuant to clause (c) of the definition of the term
Permitted Investments. The Issuer will cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument
in which such Paying Agent shall agree with the Indenture Trustee (and if the
Indenture Trustee acts as Paying Agent, it hereby so agrees), subject to the
provisions of this Section, that such Paying Agent will:

            (1) allocate all sums received for payment to the Holders of Notes
      on each Distribution Date among such Holders in the proportion specified
      in the applicable Distribution Date Statement, in each case to the extent
      permitted by applicable law;

            (2) hold all sums held by it for the payment of amounts due with
      respect to the Notes in trust for the benefit of the Persons entitled
      thereto until such sums shall be paid to such Persons or otherwise
      disposed of as herein provided and pay such sums to such Persons as herein
      provided;

            (3) if such Paying Agent is not the Indenture Trustee, immediately
      resign as a Paying Agent and forthwith pay to the Indenture Trustee all
      sums held by it in trust for the payment of the Notes if at any time the
      Paying Agent ceases to meet the standards set forth above required to be
      met by a Paying Agent at the time of its appointment;

            (4) if such Paying Agent is not the Indenture Trustee, give the
      Indenture Trustee notice of any Default by the Issuer (or any other
      obligor upon the Notes) in the making of any payment required to be made
      with respect to any Notes for which it is acting as Paying Agent;

            (5) if such Paying Agent is not the Indenture Trustee, at any time
      during the continuance of any such Default, upon the written request of
      the Indenture Trustee, forthwith pay to the Indenture Trustee all sums so
      held in trust by such Paying Agent; and

                                      -29-
<PAGE>

            (6) comply with all requirements of the Code, and all regulations
      thereunder, with respect to withholding from any payments made by it on
      any Notes of any applicable withholding taxes imposed thereon and with
      respect to any applicable reporting requirements in connection therewith;
      provided, however, that with respect to withholding and reporting
      requirements applicable to original issue discount (if any) on any of the
      Notes, the Issuer has provided the calculations pertaining thereto to the
      Indenture Trustee and the Paying Agent.

      The Issuer may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or any other purpose, by Issuer Order direct any
Paying Agent, if other than the Indenture Trustee, to pay to the Indenture
Trustee all sums held in trust by such Paying Agent, such sums to be held by the
Indenture Trustee upon the same trusts as those upon which such sums were held
by such Paying Agent; and upon such payment by any Paying Agent to the Indenture
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

      Any money held by the Indenture Trustee or any Paying Agent in trust for
the payment of any amount due with respect to any Note and remaining unclaimed
for two and one-half years after such amount has become due and payable to the
Holder of such Note (or if earlier, three months before the date on which such
amount would escheat to a governmental entity under applicable law) shall be
discharged from such trust and paid to the Issuer; and the Holder of such Note
shall thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof (but only to the extent of the amounts so paid to the Issuer),
and all liability of the Indenture Trustee or such Paying Agent with respect to
such trust money shall thereupon cease. The Indenture Trustee may adopt and
employ, at the expense of the Issuer, any reasonable means of notification of
such repayment (including, but not limited to, mailing notice of such repayment
to Holders whose Notes have been called but have not been surrendered for
redemption or whose right to or interest in moneys due and payable but not
claimed is determinable from the records of the Indenture Trustee or any Agent,
at the last address of record for each such Holder).

      Section 3.04. Existence of Issuer.

      (a) Subject to Sections 3.04(b) and (c) and Section 6.2(a)(ii) of the
Trust Agreement, the Issuer will keep in full effect its existence, rights and
franchises as a statutory trust under the laws of the State of Delaware or under
the laws of any other state or the United States of America, and will obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Notes, the Servicing Agreement, the
Insurance Agreement and the Mortgage Loan Contribution Agreement.

      (b) Subject to Section 3.09(vii) and written notice to the Rating
Agencies, any entity into which the Issuer may be merged or with which it may be
consolidated, or any entity resulting from any merger or consolidation to which
the Issuer shall be a party, shall be the successor Issuer under this Indenture
without the execution or filing of any paper, instrument or further act to be
done on the part of the parties hereto, anything in any agreement relating to
such merger or consolidation, by which any such Issuer may seek to retain
certain powers, rights and

                                      -30-
<PAGE>

privileges therefore obtaining for any period of time following such merger or
consolidation to the contrary notwithstanding (other than Section 3.09(vii)).

      (c) Upon any consolidation or merger of or other succession to the Issuer
in accordance with this Section 3.04, the Person formed by or surviving such
consolidation or merger (if other than the Issuer) may exercise every right and
power of, and shall have all of the obligations of, the Issuer under this
Indenture with the same effect as if such Person had been named as the Issuer
herein.

      Section 3.05. Protection of Trust Fund.

      (a) The Issuer will from time to time execute and deliver all such
supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,

            (i) Grant more effectively all or any portion of the Trust Fund;

            (ii) maintain or preserve the lien of this Indenture or carry out
      more effectively the purposes hereof;

            (iii) perfect, publish notice of or protect the validity of any
      Grant made or to be made by this Indenture;

            (iv) enforce any of the Mortgage Loans, the Servicing Agreement or
      the Mortgage Loan Purchase Agreement; or

            (v) preserve and defend title to the Trust Fund and the rights of
      the Indenture Trustee, and of the Noteholders, in the Mortgage Loans and
      the other property held as part of the Trust Fund against the claims of
      all Persons and parties.

      (b) The Indenture Trustee shall not remove any portion of the Trust Fund
that consists of money or is evidenced by an instrument, certificate or other
writing from the jurisdiction in which it was held, or to which it is intended
to be removed, as described in the Opinion of Counsel delivered at the Closing
Date pursuant to Section 2.1l(c), or cause or permit ownership or the pledge of
any portion of the Trust Fund that consists of book-entry securities to be
recorded on the books of a Person located in a different jurisdiction from the
jurisdiction in which such ownership or pledge was recorded at such time unless

respect to such property will continue to be maintained after giving effect to
such action or actions.

financing statements and continuation statements that will, in the opinion of
such counsel, be required to maintain the lien and security interest of this
Indenture until December 31st of the following calendar year.

under this Indenture.

extent permitted by applicable law, which right is absolute and unconditional,
to receive payment of each installment of interest on such Note on the
respective Distribution Date for such installments of interest, to receive
payment of each installment of principal of such Note when due (or, in the case
of any Note called for redemption, on the date fixed for such redemption) and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

      Section 5.10. Restoration of Rights and Remedies.

      If the Indenture Trustee or any Noteholder has instituted any Proceeding
to enforce any right or remedy under this Indenture and such Proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Indenture Trustee or to such Noteholder, then and in every such case the
Issuer, the Indenture Trustee and the Noteholders shall, subject to any
determination in such Proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Indenture Trustee and the Noteholders shall continue as though no such
Proceeding had been instituted.

      Section 5.11. Rights and Remedies Cumulative.

      No right or remedy herein conferred upon or reserved to the Indenture
Trustee or to the Noteholders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

      Section 5.12. Delay or Omission Not Waiver.

      No delay or omission of the Indenture Trustee or of any Holder of any Note
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Indenture Trustee or to the Noteholders may be exercised from time to
time, and as often as may be deemed expedient, by the Indenture Trustee or by
the Noteholders, as the case may be.

      Section 5.13. Control by Noteholders.

      The Holders of Notes representing more than 50% of the Principal Balance
of the Outstanding Notes on the applicable Record Date shall have the right to
direct the time, method and place of conducting any Proceeding for any remedy
available to the Indenture Trustee or exercising any trust or power conferred on
the Indenture Trustee; provided that:

            (1) such direction shall not be in conflict with any rule of law or
      with this Indenture;

            (2) any direction to the Indenture Trustee to undertake a Sale of
      the Trust Fund shall be by the Holders of Notes representing the
      percentage of the Principal Balance of the Outstanding Notes specified in
      Section 5.17(b)(1), unless Section 5.17(b)(2) is applicable; and

            (3) the Indenture Trustee may take any other action deemed proper by
      the Indenture Trustee that is not inconsistent with such direction;
      provided, however, that, subject to Section 6.01, the Indenture Trustee
      need not take any action that it determines might involve it in liability
      or be unjustly prejudicial to the Noteholders not consenting.

      Section 5.14. Waiver of Past Defaults.

      The Holders of Notes representing more than 50% of the Principal Balance
of the Outstanding Notes on the applicable Record Date may on behalf of the
Holders of all the Notes, waive any past Default hereunder and its consequences,
except a Default:

            (1) in the payment of principal or any installment of interest on
      any Note; or

                                      -42-
<PAGE>

            (2) in respect of a covenant or provision hereof that under Section
      9.02 cannot be modified or amended without the consent of the Holder of
      each Outstanding Note affected.

      Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

      Section 5.15. Undertaking for Costs.

      All parties to this Indenture agree, and each Holder of any Note by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Indenture Trustee for any action
taken, suffered or omitted by it as Indenture Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Indenture Trustee, to any suit instituted by any Noteholder, or group of
Noteholders, holding in the aggregate Notes representing more than 10% of the
Principal Balance of the Outstanding Notes or for the enforcement of the payment
of principal of any Note on or after the Final Maturity Date (or, in the case of
any Note called for redemption, on or after the applicable Redemption Date).

      Section 5.16. Waiver of Stay or Extension Laws.

      The Issuer covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension of law wherever enacted,
now or at any time hereafter in force, that may affect the covenants in, or the
performance of, this Indenture; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Indenture Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

      Section 5.17. Sale of Trust Fund.

      (a) The power to effect any sale (a "Sale") of any portion of the Trust
Fund pursuant to Section 5.04 shall not be exhausted by any one or more Sales as
to any portion of the Trust Fund remaining unsold, but shall continue unimpaired
until the entire Trust Fund shall have been sold or all amounts payable on the
Notes and under this Indenture with respect thereto shall have been paid. The
Indenture Trustee may from time to time postpone any public Sale by public
announcement made at the time and place of such Sale.

      (b) To the extent permitted by law, the Indenture Trustee shall not in any
private Sale sell or otherwise dispose of the Trust Fund, or any portion
thereof, unless:

                                      -43-
<PAGE>

            (1) the Holders of Notes representing not less than 50% of the
      Principal Balance of the Notes then Outstanding consent to or direct the
      Indenture Trustee to make such Sale; or

            (2) the proceeds of such Sale would be not less than the entire
      amount that would be payable to the Holders of the Notes, in full payment
      thereof in accordance with Section 5.07, on the Distribution Date next
      succeeding the date of such Sale.

      The purchase by the Indenture Trustee of all or any portion of the Trust
Fund at a private Sale shall not be deemed a Sale or disposition thereof for
purposes of this Section 5.17(b).

      (c) Unless the Holders of all Outstanding Notes have otherwise consented
or directed the Indenture Trustee, at any public Sale of all or any portion of
the Trust Fund at which a minimum bid equal to or greater than the amount
described in paragraph (2) of subsection (b) of this Section 5.17 has not been
established by the Indenture Trustee and no Person bids an amount equal to or
greater than such amount, the Indenture Trustee, acting in its capacity as
Indenture Trustee on behalf of the Noteholders, shall prevent such sale and bid
an amount (which shall include the Indenture Trustee's right, in its capacity as
Indenture Trustee, to credit bid) at least $1.00 more than the highest other bid
in order to preserve the Trust Fund on behalf of the Noteholders.

      (d) In connection with a Sale of all or any portion of the Trust Fund:

            (1) any Holder or Holders of Notes may bid for and purchase the
      property offered for Sale, and upon compliance with the terms of sale may
      hold, retain and possess and dispose of such property, without further
      accountability, and may, in paying the purchase money therefor, deliver
      any Outstanding Notes or claims for interest thereon in lieu of cash up to
      the amount that shall, upon distribution of the net proceeds of such Sale,
      be payable thereon, and such Notes, in case the amounts so payable thereon
      shall be less than the amount due thereon, shall be returned to the
      Holders thereof after being appropriately stamped to show such partial
      payment;

            (2) the Indenture Trustee may bid for and acquire the property
      offered for Sale in connection with any public Sale thereof, and, in lieu
      of paying cash therefor, may make settlement for the purchase price by
      crediting the gross Sale price against the sum of (A) the amount that
      would be payable to the Holders of the Notes as a result of such Sale in
      accordance with Section 5.07 on the Distribution Date next succeeding the
      date of such Sale and (B) the expenses of the Sale and of any Proceedings
      in connection therewith which are reimbursable to it, without being
      required to produce the Notes in order to complete any such Sale or in
      order for the net Sale price to be credited against such Notes, and any
      property so acquired by the Indenture Trustee shall be held and dealt with
      by it in accordance with the provisions of this Indenture;

            (3) the Indenture Trustee shall execute and deliver an appropriate
      instrument of conveyance transferring its interest in any portion of the
      Trust Fund in connection with a Sale thereof,

                                      -44-
<PAGE>

            (4) the Indenture Trustee is hereby irrevocably appointed the agent
      and attorney-in-fact of the Issuer to transfer and convey its interest in
      any portion of the Trust Fund in connection with a Sale thereof, and to
      take all action necessary to effect such Sale; and

            (5) no purchaser or transferee at such a Sale shall be bound to
      ascertain the Indenture Trustee's authority, inquire into the satisfaction
      of any conditions precedent or see to the application of any moneys.

      Section 5.18. Action on Notes.

      The Indenture Trustee's right to seek and recover judgment under this
Indenture shall not be affected by the seeking, obtaining or application of any
other relief under or with respect to this Indenture. Neither the lien of this
Indenture nor any rights or remedies of the Indenture Trustee or the Holders of
Notes shall be impaired by the recovery of any judgment by the Indenture Trustee
against the Issuer or by the levy of any execution under such judgment upon any
portion of the Trust Fund.

      Section 5.19. No Recourse to Other Trust Funds or Other Assets of the
Issuer.

      The Trust Fund Granted to the Indenture Trustee as security for the Notes
serves as security only for the Notes. Holders of the Notes shall have no
recourse against the Trust Fund granted as security for any other series of
Notes issued by the Issuer, and no judgment against the Issuer for any amount
due with respect to the Notes may be enforced against either the Trust Fund
securing any other series or any other assets of the Issuer, nor may any
prejudgment lien or other attachment be sought against any such other Trust Fund
or any other assets of the Issuer.

                              THE INDENTURE TRUSTEE

      Section 6.01. Duties of Indenture Trustee.

      (a) If an Event of Default has occurred and is continuing, the Indenture
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

      (b) Except during the continuance of an Event of Default:

            (1) The Indenture Trustee need perform only those duties that are
      specifically set forth in this Indenture and no others and no implied
      covenants or obligations shall be read into this Indenture against the
      Indenture Trustee; and

                                      -45-
<PAGE>

            (2) In the absence of bad faith on its part, the Indenture Trustee
      may request and conclusively rely, as to the truth of the statements and
      the correctness of the opinions expressed therein, upon certificates or
      opinions furnished to the Indenture Trustee and conforming to the
      requirements of this Indenture. The Indenture Trustee shall, however,
      examine such certificates and opinions to determine whether they conform
      on their face to the requirements of this Indenture.

      (c) The Indenture Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

            (1) This paragraph does not limit the effect of subsection (b) of
      this Section 6.01;

            (2) The Indenture Trustee shall not be liable for any error of
      judgment made in good faith by a Responsible Officer, unless it is proved
      that the Indenture Trustee was negligent in ascertaining the pertinent
      facts; and

            (3) The Indenture Trustee shall not be liable with respect to any
      action it takes or omits to take in good faith in accordance with a
      direction received by it pursuant to Section 5.13 or 5.17 or exercising
      any trust or power conferred upon the Indenture Trustee under this
      Indenture.

      (d) Except with respect to duties of the Indenture Trustee prescribed by
the TIA, as to which this Section 6.01(d) shall not apply, for all purposes
under this Indenture, the Indenture Trustee shall not be deemed to have notice
or knowledge of any Event of Default described in Section 5.01(2), 5.01(5) or
5.01(6) or any Default described in Section 5.01(3) or 5.01(4) or of any event
described in Section 3.05 unless a Responsible Officer assigned to and working
in the Indenture Trustee's corporate trust department has actual knowledge
thereof or unless written notice of any event that is in fact such an Event of
Default or Default is received by the Indenture Trustee at the Corporate Trust
Office, and such notice references the Notes generally, the Issuer, the Trust
Fund or this Indenture.

      (e) No provision of this Indenture shall require the Indenture Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

      (f) Every provision of this Indenture that in any way relates to the
Indenture Trustee is subject to the provisions of this Section.

      (g) Notwithstanding any extinguishment of all right, title and interest of
the Issuer in and to the Trust Fund following an Event of Default and a
consequent declaration of acceleration of the Maturity of the Notes, whether
such extinguishment occurs through a Sale of the Trust Fund to another Person,
the acquisition of the Trust Fund by the Indenture Trustee or otherwise, the
rights, powers and duties of the Indenture Trustee with respect to the Trust
Fund (or the proceeds thereof) and the Noteholders and the rights of Noteholders
shall continue to be governed by the terms of this Indenture.

Trustee, the Indenture Trustee shall t, within 90 days after the occurrence of
any Default known to the Indenture Trustee, the Indenture Trustee shall transmit

Indenture Trustee provide notice, or fail to provide notice of a Default known

Indenture Act. Concurrently with the mailing of any such notice to the Holders

fact or matter stated in any such document.

      (b) Before the Indenture Trustee acts or refrains from acting, it may
require an Officer's Certificate or an Opinion of Counsel reasonably
satisfactory in form and substance to the Indenture Trustee. The Indenture
Trustee shall not be liable for any action it takes or omits to take in good

      The recitals contained herein and in the Notes, except the certificates of
authentication on the Notes, shall be taken as the statements of the Issuer, and

their correctness. The Indenture Trustee makes no representations with respect
to the Trust Fund or as to the validity or sufficiency of this Indenture or of
the Notes. The Indenture Trustee shall not be accountable for the use or

hereinafter specified in this Article.

      Section 6.09. Resignation and Removal; Appointment of Successor.

      (a) No resignation or removal of the Indenture Trustee and no appointment

Section 6.10.

      (b) The Indenture Trustee may resign at any time by giving written notice
thereof to the Issuer and each Rating Agency, in which event the Issuer will

Trustee within 30 days after the giving of such notice of resignation, the
resigning Indenture Trustee may petition any court of competent jurisdiction for
the appointment of a successor Indenture Trustee.

      (c) The Indenture Trustee may be removed at any time by Act of the Holders
representing at least 51% of the Principal Balance of the Outstanding Notes, by

                                      -48-
<PAGE>

            (1) the Indenture Trustee shall have a conflicting interest
      prohibited by Section 6.07 and shall fail to resign or eliminate such
      conflicting interest in accordance with Section 6.07 after written request
      therefor by the Issuer or by any Noteholder; or

            (2) the Indenture Trustee shall cease to be eligible under Section
      6.08 or shall become incapable of acting or shall be adjudged a bankrupt
      or insolvent, or a receiver of the Indenture Trustee or of its property
      shall be appointed, or any public officer shall take charge or control of
      the Indenture Trustee or of its property or affairs for the purpose of
      rehabilitation, conservation or liquidation;

then, in any such case, (i) the Issuer by an Issuer Order may remove the
Indenture Trustee, and the Issuer shall join with the Indenture Trustee in the
execution, delivery and performance of all instruments and agreements necessary
or proper to appoint a successor Indenture Trustee and to vest in such successor
Indenture Trustee any property, title, right or power deemed necessary or
desirable, subject to the other provisions of this Indenture; provided, however,
if the Issuer does not join in such appointment within fifteen (15) days after
the receipt by it of a request to do so, or in case an Event of Default has
occurred and is continuing, the Indenture Trustee may petition a court of
competent jurisdiction to make such appointment, or (ii) subject to Section
5.15, and, in the case of a conflicting interest as described in clause (1)
above, unless the Indenture Trustee's duty to resign has been stayed as provided
in TIA Section 310(b), any Noteholder who has been a bona fide Holder of a Note
for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Indenture Trustee and the appointment of a successor Indenture Trustee.

      (e) If the Indenture Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of the Indenture Trustee
for any cause, the Issuer, by an Issuer Order shall promptly appoint a successor
Indenture Trustee. If within one year after such resignation, removal or
incapability or the occurrence of such vacancy a successor Indenture Trustee
shall be appointed by Act of the Holders of Notes representing more than 50% of
the Principal Balance of the Outstanding Notes delivered to the Issuer and the
retiring Indenture Trustee, the successor Indenture Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor
Indenture Trustee and supersede the successor Indenture Trustee appointed by the
Issuer. If no successor Indenture Trustee shall have been so appointed by the
Issuer or Noteholders and shall have accepted appointment in the manner
hereinafter provided, any Noteholder who has been a bona fide Holder of a Note
for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Indenture Trustee.

      (f) The Issuer shall give notice of each resignation and each removal of
the Indenture Trustee and each appointment of a successor Indenture Trustee to
the Holders of Notes. Each notice shall include the name of the successor
Indenture Trustee and the address of its Corporate Trust Office.

instrument accepting such appointment,

                                      -49-
<PAGE>

and thereupon the resignation or removal of the retiring Indenture Trustee shall
become effective and such successor Indenture Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Indenture Trustee. Notwithstanding the foregoing, on
request of the Issuer or the successor Indenture Trustee, such retiring
Indenture Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Indenture Trustee all the rights,
powers and trusts of the retiring Indenture Trustee, and shall duly assign,
transfer and deliver to such successor Indenture Trustee all property and money
held by such retiring Indenture Trustee hereunder. Upon request of any such
successor Indenture Trustee, the Issuer shall execute and deliver any and all
instruments for more fully and certainly vesting in and confirming to such
successor Indenture Trustee all such rights, powers and trusts.

      No successor Indenture Trustee shall accept its appointment unless at the
time of such acceptance such successor Indenture Trustee shall be qualified and
eligible under this Article.

      Section 6.11. Merger, Conversion, Consolidation or Succession to Business
of Indenture Trustee.

converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Indenture Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Indenture Trustee, shall be the successor of
the Indenture Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case
any Notes have been authenticated, but not delivered, by the Indenture Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Indenture Trustee may adopt such authentication and deliver the
Notes so authenticated with the same effect as if such successor Indenture
Trustee had authenticated such Notes.

      Section 6.12. Preferential Collection of Claims Against Issuer.

      The Indenture Trustee (and any co-trustee or separate trustee) shall be
subject to TIA Section 311(a), excluding any creditor relationship listed in TIA
Section 31l(b), and an Indenture Trustee (and any co-trustee or separate
trustee) who has resigned or been removed shall be subject to TIA Section 311(a)
to the extent indicated.

      Section 6.13. Co-Indenture Trustees and Separate Indenture Trustees.

      At any time or times, for the purpose of meeting the legal requirements of
the TIA or of any jurisdiction in which any of the Trust Fund may at the time be
located, the Indenture Trustee shall have power to appoint, and, upon the
written request of the Indenture Trustee or of the Holders of Notes representing
more than 50% of the Principal Balance of the Outstanding Notes with respect to
which a co-trustee or separate trustee is being appointed, the Issuer shall for
such purpose jointly with the Indenture Trustee in the execution, delivery and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Indenture Trustee either to act as
co-trustee, jointly with the Indenture Trustee, of all or any part

                                      -50-
<PAGE>

of the Trust Fund, or to act as separate trustee of any such property, in either
case with such powers as may be provided in the instrument of appointment, and
to vest in such Person or Persons in the capacity aforesaid, any property,
title, right or power deemed necessary or desirable, subject to the other
provisions of this Section. If the Issuer does not join in such appointment
within 15 days after the receipt by it of a request to do so, or in case an
Event of Default has occurred and is continuing, the Indenture Trustee alone
shall have power to make such appointment. All fees and expenses of any
co-trustee or separate trustee shall be payable by the Issuer.

      Should any written instrument from the Issuer be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right or power, any and all
such instruments shall, on request, be executed, acknowledged and delivered by
the Issuer.

      Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following terms:

            (1) The Notes shall be authenticated and delivered and all rights,
      powers, duties and obligations hereunder in respect of the custody of
      securities, cash and other personal property held by, or required to be
      deposited or pledged with, the Indenture Trustee hereunder, shall be
      exercised, solely by the Indenture Trustee.

            (2) The rights, powers, duties and obligations hereby conferred or
      imposed upon the Indenture Trustee in respect of any property covered by
      such appointment shall be conferred or imposed upon and exercised or
      performed by the Indenture Trustee or by the Indenture Trustee and such
      co-trustee or separate trustee jointly, as shall be provided in the
      instrument appointing such co-trustee or separate trustee, except to the
      extent that under any law of any jurisdiction in which any particular act
      is to be performed, the Indenture Trustee shall be incompetent or
      unqualified to perform such act, in which event such rights, powers,
      duties and obligations shall be exercised and performed by such co-trustee
      or separate trustee.

            (3) The Indenture Trustee at any time, by an instrument in writing,
      executed by it, with the concurrence of the Issuer evidenced by an Issuer
      Order, may accept the resignation of or remove any co-trustee or separate
      trustee appointed under this Section, and, in case an Event of Default has
      occurred and is continuing, the Indenture Trustee shall have power to
      accept the resignation of, or remove, any such co-trustee or separate
      trustee without the concurrence of the Issuer upon the written request of
      the Indenture Trustee, the Issuer shall join with the Indenture Trustee in
      the execution, delivery and performance of all instruments and agreements
      necessary or proper to effectuate such resignation or removal. A successor
      to any co-trustee or separate trustee so resigned or removed may be
      appointed in the manner provided in this Section.

            (4) No co-trustee or separate trustee hereunder shall be personally
      liable by reason of any act or omission of the Indenture Trustee, or any
      other such trustee hereunder.

                                      -51-
<PAGE>

            (5) Any Act of Noteholders delivered to the Indenture Trustee shall
      be deemed to have been delivered to each such co-trustee and separate
      trustee.

      Section 6.14. Authenticating Agents.

      The Issuer shall appoint an Authenticating Agent with power to act on its
behalf and subject to its direction in the authentication and delivery of the
Notes designated for such authentication by the Issuer and containing provisions
therein for such authentication (or with respect to which the Issuer has made
other arrangements, satisfactory to the Indenture Trustee and such
Authenticating Agent, for notation on the Notes of the authority of an
Authenticating Agent appointed after the initial authentication and delivery of
such Notes) in connection with transfers and exchanges under Section 2.06, as
fully to all intents and purposes as though the Authenticating Agent had been
expressly authorized by that Section to authenticate and deliver Notes. For all
purposes of this Indenture (other than in connection with the authentication and
delivery of Notes pursuant to Sections 2.05 and 2.11 in connection with their
initial issuance), the authentication and delivery of Notes by the
Authenticating Agent pursuant to this Section shall be deemed to be the
authentication and delivery of Notes "by the Indenture Trustee." Such
Authenticating Agent shall at all times be a Person that both meets the
requirements of Section 6.07 for the Indenture Trustee hereunder and has an
office for presentation of Notes in the United States of America. The Indenture
Trustee shall initially be the Authenticating Agent and shall be the Note
Registrar as provided in Section 2.06. The office from which the Indenture
Trustee shall perform its duties as Note Registrar and Authenticating Agent
shall be the Corporate Trust Office. Any Authenticating Agent appointed pursuant
to the terms of this Section 6.14 or pursuant to the terms of any supplemental
indenture shall deliver to the Indenture Trustee as a condition precedent to the
effectiveness of such appointment an instrument accepting the trusts, duties and
responsibilities of Authenticating Agent and of Note Registrar or co-Note
Registrar and indemnifying the Indenture Trustee for and holding the Indenture
Trustee harmless against, any loss, liability or expense (including reasonable
attorneys' fees) incurred without negligence or bad faith on its part, arising
out of or in connection with the acceptance, administration of the trust or
exercise of authority by such Authenticating Agent, Note Registrar or co-Note
Registrar.

      Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of the Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section, without the execution or filing of any further act on the part of the
parties hereto or the Authenticating Agent or such successor corporation.

      Any Authenticating Agent may at any time resign by giving written notice
of resignation to the Issuer. The Issuer may at any time terminate the agency of
any Authenticating Agent by giving written notice of termination to such
Authenticating Agent and the Issuer. Upon receiving such a notice of resignation
or upon such a termination, or in case at any time any Authenticating Agent
shall cease to be eligible under this Section, the Issuer shall promptly appoint
a successor Authenticating Agent, shall give written notice of such appointment
to the Indenture Trustee, and shall mail notice of such appointment to all
Holders of Notes.

      The Indenture Trustee agrees, subject to Section 6.01(e), to pay to any
Authenticating Agent from time to time reasonable compensation for its services
and the Indenture Trustee shall be entitled to be reimbursed for such payments
pursuant to Section 6.04 of the Servicing Agreement. The provisions of Sections
2.09, 6.04 and 6.05 shall be applicable to any Authenticating Agent.

      Section 6.15. Review of Mortgage Files.

      (a) Initial Certification. The Indenture Trustee shall, for the benefit of
the Noteholders, cause the Custodian to review each Custodial File as set forth
in the Servicing Agreement, and shall cause the Custodian to deliver to the
Seller, the Depositor, the Securities Administrator, the Indenture Trustee and
the Servicer on the Closing Date an Initial Certification in the form attached
as Exhibit E-1 to the Custodial Agreement with respect to each Mortgage Loan to
the effect that, except as specifically noted on a schedule of exceptions
thereto, (A) all documents required to be contained in the Custodial File are in
its possession, (B) such documents have been reviewed by it and appear regular
on their face and relate to such Mortgage Loan, and (C) based on its examination
and only as to the foregoing documents, the information set forth on the related
Mortgage Loan Schedule accurately reflects information set forth in the
Custodial File.

      (b) Final Certification. On or before one year following the Closing Date,
the Indenture Trustee shall cause the Custodian to deliver to the Seller, the
Depositor, the Securities Administrator, the Indenture Trustee and the Servicer
a Final Certification in the form attached as Exhibit E-2 to the Custodial
Agreement evidencing the completeness of the Custodial File for each Mortgage
Loan, except as specifically noted on a schedule of exceptions thereto.

      (c) In giving each of the Initial Certification and the Final
Certification, neither the Indenture Trustee nor the Custodian shall be under
any duty or obligation to inspect, review or examine any such documents,
instruments, securities or other papers to determine that they or the signatures
thereto are genuine, enforceable, or appropriate for the represented purpose or
that they have actually been recorded or that they are other than what they
purport to be on their face.

      (d) Recordation Report. In the event that the Mortgage Loans are required
to be recorded in accordance with the provisions of the Mortgage Loan Purchase
Agreement, no later than the fifth Business Day of each third month, commencing
in [___________], the Indenture Trustee shall cause the Custodian to deliver to
the Servicer a recordation report dated as of the first day of such month,
identifying those Mortgage Loans for which it has not yet received (1) an
original recorded Mortgage or a copy thereof certified to be true and correct by
the public recording office in possession of such Mortgage or (2) an original
recorded Assignment of the Mortgage to the Indenture Trustee and any required
intervening Assignments or a copy thereof certified to be a true and correct
copy by the public recording office in possession of such Assignment.

      Section 6.16. Indenture Trustee Fees and Expenses.

      The Securities Administrator shall pay any fees of the Indenture Trustee
Fee on each Distribution Date as provided herein.

                                      -54-
<PAGE>

forth in the Distribution Date Statement pursuant to Section 2.08(d), also mail

                                  ARTICLE VIII

           ACCOUNTS, PAYMENTS OF INTEREST AND PRINCIPAL, AND RELEASES

      Section 8.01. Collection of Moneys.

      Except as otherwise expressly provided herein, the Indenture Trustee may
demand payment or delivery of, and shall receive and collect, directly and
without intervention or assistance of any fiscal agent or other intermediary,
all money and other property payable to or receivable by the Indenture Trustee
pursuant to this Indenture. The Indenture Trustee shall hold all such money and
property received by it as part of the Trust Fund and shall apply it as provided
in this Indenture.

      If the Indenture Trustee shall not have received the Available Funds by
close of business on any related Remittance Date, the Indenture Trustee shall,
unless the Issuer or the Servicer shall have made provisions satisfactory to the
Indenture Trustee for delivery to the Indenture Trustee of an amount equal to
such Available Funds, deliver a notice to the Issuer and the Servicer of their
failure to remit such Available Funds and that such failure, if not remedied by
the close of business on the Business Day after the date upon which such notice
is delivered to the Servicer, shall constitute an event of default under the
Servicing Agreement. If the Indenture Trustee shall subsequently receive any
such Available Funds by 2:00 p.m. Eastern Time on such Business Day, such Event
of Default shall not be deemed to have occurred. Notwithstanding any other
provision hereof, the Indenture Trustee shall deliver to the Issuer or the
Servicer, or their respective designee or assignee, any Available Funds received
with respect to a Mortgage Loan after the related Remittance Date to the extent
that the Issuer or the Servicer, respectively,

                                      -55-
<PAGE>

previously made payment or provision for payment with respect to such Available
Funds in accordance with this Section 8.01, and any such Available Funds shall
not be deemed part of the Trust Fund.

      Except as otherwise expressly provided in this Indenture and the Servicing
Agreement, if, following delivery by the Indenture Trustee of the notice
described above, the Servicer shall fail to remit the Available Funds on any
Remittance Date, the Indenture Trustee shall deliver a second notice to the
Servicer and the Issuer by 2:00 p.m. Eastern Time on the third Business Day
prior to the related Distribution Date indicating that an event of default
occurred and is continuing under the Servicing Agreement. In addition, if a
default occurs in any other performance required under the Servicing Agreement,
the Indenture Trustee may, or upon instruction by the Holders of Notes
representing more than 50% of the Principal Balance of the Outstanding Notes
shall, take such action as may be appropriate to enforce such payment or
performance including the institution and prosecution of appropriate
Proceedings. Any such action shall be without prejudice to any right to claim a
Default or Event of Default under this Indenture and to proceed thereafter as
provided in Article V.

      Section 8.02. Note Account; Distributions.

      (a) The Issuer hereby directs the Indenture Trustee to establish, at the
Corporate Trust Office, one or more separate trust accounts that shall
collectively be the "Note Account" on or before the Closing Date. The Indenture
Trustee shall promptly deposit in the Note Account (i) all Available Funds
received by it from the Servicer pursuant to the Servicing Agreement, (ii) any
other funds from any deposits to be made by the Servicer pursuant to the
Servicing Agreement, (iii) any amount required to be deposited in the Note
Account pursuant to Section 8.01, (iv) all amounts received pursuant to Section
8.03, and (v) all other amounts received for deposit in the Note Account,
including the payment of any Purchase Price for a Mortgage Loan received by the
Indenture Trustee. All amounts that are deposited from time to time in a Note
Account are subject to withdrawal by the Indenture Trustee for the purposes set
forth in subsections (c) and (d) of this Section 8.02. All funds withdrawn from
the Note Account pursuant to subsection (c) of this Section 8.02 for the purpose
of making payments to the Holders of Notes shall be applied in accordance with
Section 3.03.

      (b) So long as no Default or Event of Default shall have occurred and be
continuing, amounts held in the Note Accounts shall be invested in Permitted
Investments, which Permitted Investments shall mature no later than the Business
Day preceding the immediately following Distribution Date.

      All income or other gains, if any, from investment of moneys deposited in
the Note Accounts shall be for the benefit of the Servicer and on each
Distribution Date, any such amounts may be released from the Note Accounts and
paid to the Servicer as part of its compensation for acting as Servicer. Any
loss resulting from such investment of moneys deposited in a Note Account shall
be reimbursed immediately as incurred to the Note Account by the Servicer.
Subject to Section 6.01 and the preceding sentence, neither the Indenture
Trustee nor the Servicer shall in any way be held liable by reason of any
insufficiency in the Note Accounts.

      (c) On each Distribution Date, the Indenture Trustee shall withdraw
amounts on deposit in the Note Account and pay on a pari passu basis the
Securities Administrator Fee, Transition Expenses, any gains or income from
investments on the Note Account to the Servicer and, provided notice is given to
the Indenture Trustee no later than the fourth Business Day prior to the
Distribution Date and to the extent such amounts have not been withdrawn
pursuant to Sections 3.04 of the Servicing Agreement, amounts required to pay
the Servicer any unpaid Servicing Fees then due and to reimburse the Servicer
for Advances and Servicing Advances previously made by, and not previously
reimbursed to or retained by, the Servicer, which are so reimbursable to the
Servicer pursuant to the Servicing Agreement (as reported in writing by the
Servicer to the Indenture Trustee). After payment of such amounts, unless the
Notes have been declared due and payable pursuant to Section 5.02 and moneys
collected by the Indenture Trustee are being applied in accordance with Section
5.07, Available Funds on deposit in the Note Account on any Distribution Date or
Redemption Date shall be withdrawn from such Note Account, in the amounts
required, for application on such Distribution Date as follows:

            (i) first, to the Noteholders, the Accrued Note Interest with
      respect to such Distribution Date;

            (ii) second, to the Noteholders, the amount of Monthly Principal for
      the Notes with respect to such Distribution Date, in reduction of the
      Principal Balance until the Principal Balance is reduced to zero;

            (iii) third, to the Noteholders, the Overcollateralization
      Deficiency, if any, on such Distribution Date (after giving effect to
      application of Monthly Principal for such Distribution Date), in reduction
      of the Principal Balance until the Principal Balance is reduced to zero;
      and

            (iv) fourth, to the Issuer, as set forth in the Trust Agreement, any
      remaining amounts.

      (d) On or after each Distribution Date, so long as the Indenture Trustee
shall have prepared a Distribution Date Statement in respect of such
Distribution Date and (1) shall have made, or, in accordance with Section 3.03,
set aside from amounts in the Note Account an amount sufficient to make, the
payments required to be made as set forth in Section 8.02(c) as indicated in
such Distribution Date Statement, and (2) shall have set aside any amounts that
have been deposited in the Note Account prior to such time that represent
amounts that are to be used to make payments on the Notes on the next succeeding
Distribution Date, the cash balance, if any, then remaining in such Note Account
shall be withdrawn from such Note Account by the Indenture Trustee and, so long
as no Default or Event of Default shall have occurred and be continuing, shall
be released from the lien of this Indenture and paid by the Indenture Trustee to
the Issuer.

      (e) Any payments made by the Indenture Trustee to the Issuer pursuant to
this Section 8.02 shall be remitted to the Certificate Distribution Account
established and maintained pursuant to the Trust Agreement.

      Section 8.04. General Provisions Regarding the Note Accounts and Mortgage
Loans.

      (a) Each Note Account shall relate solely to the Notes and to the Mortgage
Loans, Permitted Investments and other property securing the Notes. Funds and
other property in the Note Account shall not be commingled with any other moneys
or property of the Issuer or any Affiliate thereof except as otherwise expressly
provided for herein. Notwithstanding the foregoing, the Indenture Trustee may
hold any funds or other property received or held by it as part of the Note
Account in collective accounts maintained by it in the normal course of its
business and containing funds or property held by it for other Persons (which
may include the Issuer or an Affiliate), provided that such accounts are under
the sole control of the Indenture Trustee and the Indenture Trustee maintains
adequate records indicating the ownership of all such funds or property and the
portions thereof held for credit to a Note Account.

      (b) If any amounts are needed for payment from the Note Account and
sufficient uninvested funds are not available therein to make such payment, the
Indenture Trustee shall cause to be sold or otherwise converted to cash a
sufficient amount of the investments in such Note Account.

      (c) The Indenture Trustee shall, at all times while any Notes are
Outstanding, maintain in its possession, or in the possession of an agent whose
actions with respect to such items are under the sole control of the Indenture
Trustee, all certificates or other instruments, if any, evidencing any
investment of funds in the Note Account. The Indenture Trustee shall relinquish
possession of such items, or direct its agent to do so, only for purposes of
collecting the final payment receivable on such investment or certificate or, in
connection with the sale of any investment held in the Note Account, against
delivery of the amount receivable in connection with any sale.

      (d) The Indenture Trustee shall not invest any part of the Trust Fund in
Permitted Investments that constitute uncertificated securities (as defined in
Section 8-102 of the Uniform Commercial Code, as enacted in the relevant
jurisdiction) or in any other book-entry securities unless it has received an
Opinion of Counsel reasonably satisfactory in form and substance to the
Indenture Trustee setting forth, with respect to each type of security for which
authority to invest is being sought, the procedures that must be followed to
maintain the lien and security interest created by this Indenture with respect
to the Trust Fund.

      Section 8.05. Releases of Defective Mortgage Loans.

      Upon notice or discovery that any of the representations or warranties of
the Depositor set forth in Section [__] of the Trust Agreement was materially
incorrect or otherwise misleading with respect to any Mortgage Loan as of the
time made, the Indenture Trustee shall direct the Depositor to either (i) within
60 days after the Depositor receives actual knowledge of such incorrectness,
eliminate or otherwise cure the circumstance or condition in respect of which
such representation or warranty was incorrect as of the time made, (ii) withdraw
such Defective Mortgage Loan from the lien of this Indenture following the
expiration of such 60-day period by

                                      -58-

depositing to the Note Account an amount equal to the Purchase Price for such
Mortgage Loan or (iii) substitute a Qualified Replacement Mortgage Loan for such
Defective Mortgage Loan and deposit any Purchase Price required to be paid in
connection with such substitution pursuant to Section [_] of the Trust
Agreement, all as provided in Section [_] of the Trust Agreement. Upon any
purchase of or substitution for a Defective Mortgage Loan by the Depositor in
accordance with Section [_] of the Trust Agreement, the Indenture Trustee shall
deliver the Mortgage File relating to such Defective Mortgage Loan to the
Depositor, and the Issuer and the Indenture Trustee shall execute such
instruments of transfer as are necessary to convey title to such Defective
Mortgage Loan to the Depositor from the lien of this Indenture.

      Section 8.06. Reports by Securities Administrator to Noteholders; Access
to Certain Information.

      On each Distribution Date, the Securities Administrator shall make
available the written report required by Section 2.08(d) to Noteholders of
record as of the related Record Date (including the Clearing Agency, if any) via
the Depositor's internet website. Assistance in using the website service can be
obtained by calling the Depositor at (301) 846-8881. Noteholders that are unable

all Distribution Date Statements delivered to the Issuer since the Closing Date,
(c) any Officers' Certificates delivered to the Indenture Trustee since the
Closing Date as described in the Indenture and (d) any Accountants' reports
delivered to the Indenture Trustee since the Closing Date as required under the
Servicing Agreement. Copies of any and all of the foregoing items will be
available from the Indenture Trustee upon request; however, the Indenture
Trustee will be permitted to require payment of a sum sufficient to cover the
reasonable costs and expenses of providing such copies and shall not be required
to provide such copies without reasonable assurances that such sum will be paid.

      Section 8.07. Trust Fund Mortgage Files.

      (a) The Indenture Trustee shall release Mortgage Files or portions thereof
to the Servicer on the terms specified in the Servicing Agreement.

outstanding, release all of the Trust Fund to the Issuer (other than any cash
held for the payment of the Notes pursuant to Section 3.03 or 4.02).

      Section 8.08. Amendment to Servicing Agreement.

      The Indenture Trustee may, without the consent of any Holder, enter into
or consent to any amendment or supplement to the Servicing Agreement for the
purpose of increasing the obligations or duties of any party other than the
Indenture Trustee or the Holders of the Notes. The Indenture Trustee may, in its
discretion, decline to enter into or consent to any such supplement or
amendment: (i) unless the Indenture Trustee receives an Opinion of Counsel that

                                      -59-
<PAGE>

the position of the Holders would not be materially adversely affected or
written confirmation from the Rating Agencies that the then-current implied
ratings on the Notes would not be adversely affected by such supplement or
amendment or (ii) if its own rights, duties or immunities would be adversely
affected.

      Section 8.09. Delivery of the Mortgage Files Pursuant to Servicing
Agreement.

      As is appropriate for the servicing or foreclosure of any Mortgage Loan,
the Indenture Trustee shall cause the Custodian to deliver to the Servicer of
such Mortgage the Mortgage Files for such Mortgage Loan upon receipt by the
Indenture Trustee and the Custodian on or prior to the date such release is to
be made of:

      (a) such Officers' Certificates, if any, as are required by the Servicing
Agreement; and

      (b) a "Request for Release" in the form prescribed by the Servicing
Agreement, executed by the Servicer, providing that the Servicer will hold or
retain the Mortgage Files in trust for the benefit of the Indenture Trustee and
the Holders of Notes.

      Section 8.10. Servicer as Agent.

      In order to facilitate the servicing of the Mortgage Loans by the Servicer
of such Mortgage Loans, the Servicer of the Mortgage Loans has been appointed by
the Issuer to retain, in accordance with the provisions of the Servicing
Agreement and this Indenture, all Available Funds on such Mortgage Loans prior
to their deposit into the Note Account on or prior to the related Remittance
Date.

      Section 8.11. Termination of Servicer.

      In the event of an event of default specified in Section 6.01 of the
Servicing Agreement, the Indenture Trustee may terminate the Servicer as
provided in Section 6.01 and Section 6.02 of the Servicing Agreement. If the
Indenture Trustee terminates the Servicer, the Indenture Trustee shall, pursuant
to Sections 8.01 and 8.02 of the Servicing Agreement, assume the duties of the
Servicer or appoint a successor servicer acceptable to the Issuer and the Rating
Agencies and meeting the requirements set forth in the Servicing Agreement.

      Section 8.12. Opinion of Counsel.

      The Indenture Trustee shall be entitled to receive at least five Business
Days' notice of any action to be taken pursuant to Sections 8.07(a) (other than
in connection with releases of Mortgage Loans that were the subject of a Full
Prepayment of the type described in clause (i) of the definition of the term
"Full Prepayment") and 8.08, accompanied by copies of any instruments involved,
and the Indenture Trustee shall be entitled to receive an Opinion of Counsel, in
form and substance reasonably satisfactory to the Indenture Trustee, stating the
legal effect of any such action, outlining the steps required to complete the
same, and concluding that all conditions precedent to the taking of such action
have been complied with. Counsel rendering any such opinion may rely, without
independent investigation, on the accuracy and validity of any certificate or
other instrument delivered to the Indenture Trustee in connection with any such
action.

      Section 8.13. Appointment of Custodians.

      The Indenture Trustee may, at the written direction of the Issuer and at
no additional cost to the Issuer or to the Indenture Trustee, appoint one or
more Custodians to hold all or a portion of the Mortgage Files as agent for the
Indenture Trustee. Each Custodian shall (i) be a financial institution
supervised and regulated by the Comptroller of the Currency, the Board of
Governors of the Federal Reserve System, the Office of Thrift Supervision, or
the Federal Deposit Insurance Corporation; (ii) have combined capital and
surplus of at least $10,000,000; (iii) be equipped with secure, fireproof
storage facilities, and have adequate controls on access to assure the safety
and security of the Mortgage Files; (iv) utilize in its custodial function
employees who are knowledgeable in the handling of mortgage documents and of the
functions of a mortgage document custodian; and (v) satisfy any other reasonable
requirements that the Issuer may from time to time deem necessary to protect the
interests of Noteholders in the Mortgage Files. Each Custodian shall be subject
to the same obligations and standard of care as would be imposed on the
Indenture Trustee hereunder assuming the Indenture Trustee retained the Mortgage
Files directly. The appointment of one or more Custodians shall not relieve the
Indenture Trustee from any of its obligations hereunder. If the Servicer is
appointed as a Custodian in accordance with this Section 8.13, it shall fulfill
its servicing and custodial duties and obligations through separate departments
and, if it maintains a trust department, shall fulfill its custodial duties and
obligations through such trust department.

      Section 9.01. Supplemental Indentures Without Consent of Noteholders.

      Without the consent of the Holders of any Notes, the Issuer and the

      Holders of all Notes or to surrender any right or power herein conferred

                                      -61-
<PAGE>

            (5) to cure any ambiguity, to correct or supplement any provision
      herein that may be defective or inconsistent with any other provision
      herein, or to amend any other provisions with respect to matters or
      questions arising under this Indenture, which shall not be inconsistent
      with the provisions of this Indenture, provided that such action shall not
      adversely affect in any material respect the interests of the Holders of
      the Notes or the Holders of the Certificates; and provided, further, that
      the amendment shall not be deemed to adversely affect in any material
      respect the interests of the Holders of the Notes if the Person requesting
      the amendment obtains letters from the Rating Agencies that the amendment
      would not result in the downgrading or withdrawal of the implied ratings
      then assigned to the Notes; or

            (6) to modify, eliminate or add to the provisions of this Indenture
      to such extent as shall be necessary to effect the qualification of this
      Indenture under the TIA or under any similar federal statute hereafter
      enacted, and to add to this Indenture such other provisions as may be
      expressly required by the TIA.

      Section 9.02. Supplemental Indentures With Consent of Noteholders.

      With the consent of Holders of Notes representing not less than a majority
of the Principal Balance of all Outstanding Notes by Act of said Holders
delivered to the Issuer and the Indenture Trustee, the Issuer and the Indenture
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to, or changing in any manner or eliminating
any of the provisions of, this Indenture or of modifying in any manner the
rights of the Holders of the Notes under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Note affected thereby:

            (1) change any Distribution Date or the Final Maturity Date of the
      Notes or reduce the principal amount thereof, the Interest Rate thereon or
      the Redemption Price with respect thereto, change the earliest date on
      which any Note may be redeemed at the option of the Issuer, change any
      place of payment where, or the coin or currency in which, any Note or any

      enforcement of the payment of any installment of interest due on any Note
      on or after the Final Maturity Date thereof or for the enforcement of the
      payment of the entire remaining unpaid principal amount of any Note on or
      after the Final Maturity Date (or, in the case of redemption, on or after
      the applicable Redemption Date);

            (2) reduce the percentage of the Principal Balance of the
      Outstanding Notes, the consent of the Holders of which is required for any

      Defaults hereunder and their consequences provided for in this Indenture;

            (3) modify any of the provisions of this Section, Section 5.13 or
      Section 5.17(b), except to increase any percentage specified therein or to

      or waived without the consent of the Holder of each Outstanding Note
      affected thereby;

                                      -62-
<PAGE>

            (4) modify or alter the provisions of the proviso to the definition
      of the term "Outstanding";

            (5) permit the creation of any lien other than the lien of this
      Indenture with respect to any part of the Trust Fund (except for Permitted
      Encumbrances) or terminate the lien of this Indenture on any property at
      any time subject hereto or deprive the Holder of any Note of the security
      afforded by the lien of this Indenture;

            (6) modify any of the provisions of this Indenture in such manner as
      to affect rights of the Holders of the Notes to the benefits of any
      provisions for the mandatory redemption of Notes contained herein; or

            (7) incur any indebtedness, other than the Notes, that would cause
      the Issuer or the Trust Fund to be treated as a "taxable mortgage pool"
      within the meaning of Code Section 7701(i).

      The Indenture Trustee may in its discretion determine whether or not any
Notes would be affected by any supplemental indenture and any such determination
shall be conclusive upon the Holders of all Notes, whether theretofore or
thereafter authenticated and delivered hereunder. The Indenture Trustee shall
not be liable for any such determination made in good faith.

      It shall not be necessary for any Act of Noteholders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

      Promptly after the execution by the Issuer and the Indenture Trustee of
any supplemental indenture pursuant to this Section, the Indenture Trustee shall
mail to the Holders of the Notes to which such supplemental indenture relates a
notice setting forth in general terms the substance of such supplemental
indenture. Any failure of the Indenture Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

      Section 9.03. Execution of Supplemental Indentures.

      In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Indenture Trustee shall be entitled to
receive, and (subject to Section 6.01) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Indenture Trustee may, but
shall not be obligated to, enter into any such supplemental indenture that
affects the Indenture Trustee's own rights, duties or immunities under this
Indenture or otherwise. The Issuer shall cause executed copies of any
Supplemental Indentures to be delivered to the Rating Agencies.

      Section 9.04. Effect of Supplemental Indentures.

      Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Notes to which such supplemental indenture

                                      -63-
<PAGE>

relates that have theretofore been or thereafter are authenticated and delivered
hereunder shall be bound thereby.

      Section 9.05. Conformity With Trust Indenture Act.

      Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the TIA as then in effect so long as this
Indenture shall then be qualified under the TIA.

      Section 9.06. Reference in Notes to Supplemental Indentures.

      Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and if required by the Indenture Trustee
shall, bear a notation in form approved by the Indenture Trustee as to any
matter provided for in such supplemental indenture. If the Issuer shall so
determine, new Notes so modified as to conform, in the opinion of Indenture
Trustee and the Issuer, to any such supplemental indenture may be prepared and
executed by the Issuer and authenticated and delivered by the Indenture Trustee
in exchange for Outstanding Notes.

      Section 9.07. Amendments to Governing Documents.

      The Indenture Trustee shall, subject to Sections 9.01 and 9.02 hereof,
upon Issuer Request, consent to any proposed amendment to the Issuer's governing
documents, or an amendment to or waiver of any provision of any other document
relating to the Issuer's governing documents, such consent to be given without
the necessity of obtaining the consent of the Holders of any Notes upon receipt
by the Indenture Trustee of:

            (i) an Officers' Certificate, to which such proposed amendment or
      waiver shall be attached, stating that such attached copy is a true copy
      of the proposed amendment or waiver and that all conditions precedent to
      such consent specified in this Section 9.07 have been satisfied; and

            (ii) written confirmation from the Rating Agencies that the
      implementation of the proposed amendment or waiver will not adversely
      affect their implied ratings of the Notes.

      Notwithstanding the foregoing, the Indenture Trustee may decline to
consent to a proposed waiver or amendment that adversely affects its own rights,
duties or immunities under this Indenture or otherwise.

      Nothing in this Section 9.07 shall be construed to require that any Person
obtain the consent of the Indenture Trustee to any amendment or waiver or any
provision of any document where the making of such amendment or the giving of
such waiver without obtaining the consent of the Indenture Trustee is not
prohibited by this Indenture or by the terms of the document that is the subject
of the proposed amendment or waiver.

      shall be the office or agency of the Issuer to be maintained as provided
      in Section 3.02), and that no interest shall accrue on such Note for any
      period after the date fixed for redemption.

                                      -65-
<PAGE>

      Failure to give notice of redemption, or any defect therein, to any Holder
of any Note selected for redemption shall not impair or affect the validity of
the redemption of any other Note.

      Section 10.03. Notes Payable on Optional Redemption.

      Notice of redemption having been given as provided in Section 10.02, the
Notes to be redeemed shall, on the applicable Redemption Date, become due and

payment of the Redemption Price) no interest shall accrue on such Redemption
Price for any period after such Redemption Date; provided, however, that if such

                                  MISCELLANEOUS

      Section 11.01. Compliance Certificates and Opinions.

      (a) Upon any application or request by the Issuer to the Indenture Trustee
to take any action under any provision of this Indenture, the Issuer shall
furnish to the Indenture Trustee a an Officers' Certificate stating that all
conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with and an Opinion of Counsel, if requested
by the Indenture Trustee, stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

      (b) Every certificate, opinion or letter with respect to compliance with a
condition or covenant provided for in this Indenture, including one furnished
pursuant to specific requirements of this Indenture relating to a particular
application or request (other than certificates provided pursuant to TIA Section
314(a)(4)) shall include and shall be deemed to include (regardless of whether
specifically stated therein) the following:

            (1) a statement that each individual signing such certificate,
      opinion or letter has read such covenant or condition and the definitions
      herein relating thereto;

            (2) a brief statement as to the nature and scope of the examination
      or investigation upon which the statements or opinions contained in such
      certificate, opinion or letter are based;

      made such examination or investigation as is necessary to enable him to
      express an informed opinion as to whether or not such covenant or
      condition has been complied with; and

            (4) a statement as to whether, in the opinion of each such
      individual, such condition or covenant has been complied with.

<PAGE>

      Section 11.02. Form of Documents Delivered to Indenture Trustee.

      In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

      Any certificate or opinion of the Issuer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such officer knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
the matters upon which his certificate or opinion is based are erroneous. Any
Opinion of Counsel may be based on the written opinion of other counsel, in
which event such Opinion of Counsel shall be accompanied by a copy of such other
counsel's opinion and shall include a statement to the effect that such counsel
believes that such counsel and the Indenture Trust may reasonably rely upon the
opinion of such other counsel.

      Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

      Wherever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Section 6.01(b)(2).

      Whenever in this Indenture it is provided that the absence of the
occurrence and continuation of a Default or Event of Default is a condition
precedent to the taking of any action by the Indenture Trustee at the request or
direction of the Issuer, then, notwithstanding that the satisfaction of such
condition is a condition precedent to the Issuer's right to make such request or
direction, the Indenture Trustee shall be protected in acting in accordance with
such request or direction if it does not have knowledge of the occurrence and
continuation of such Default or Event of Default as provided in Section 6.01(d).

      Section 11.03. Acts of Noteholders.

      (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Noteholders
may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Noteholders in person or by an agent duly appointed
in writing; and, except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered

                                      -67-
<PAGE>

to the Indenture Trustee, and, where it is hereby expressly required, to the
Issuer. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the
Noteholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.01) conclusive in
favor of the Indenture Trustee and the Issuer, if made in the manner provided in
this Section.

      (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Whenever
such execution is by an officer of a corporation or a member of a partnership on
behalf of such corporation or partnership, such certificate or affidavit shall
also constitute sufficient proof of his authority.

      (c) The ownership of Notes shall be proved by the Note Register.

      (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Notes shall bind the Holder of every Note
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, in respect of anything done, omitted or suffered to be done by the
Indenture Trustee or the Issuer in reliance thereon, whether or not notation of
such action is made upon such Notes.

      Section 11.04. Notices, etc., to Indenture Trustee and Issuer.

      Any request, demand, authorization, direction, notice, consent, waiver or
Act of Noteholders or other documents provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with:

            (1) the Indenture Trustee by any Noteholder or by the Issuer shall
      be sufficient for every purpose hereunder if made, given, furnished or
      filed in writing to or with and received by the Indenture Trustee at its
      Corporate Trust Office; or

            (2) the Issuer by the Indenture Trustee or by any Noteholder shall
      be sufficient for every purpose hereunder (except as provided in Section
      5.01(3) and (4)) if in writing and mailed, first-class postage prepaid, to
      the Issuer addressed to it at [______________], or at any other address
      previously furnished in writing to the Indenture Trustee by the Issuer; or

            (3) the Depositor by the Indenture Trustee or by any Noteholder
      shall be sufficient for every purpose hereunder if in writing and mailed,
      first-class, postage paid, to Wells Fargo Asset Securities Corporation,
      7485 New Horizon Way, Frederick, Maryland 21703, Attention:

      to the Indenture Trustee by the Depositor; or

            (4) the Seller or the Servicer by the Indenture Trustee or by any
      Noteholder shall be sufficient for every purpose hereunder if in writing
      and mailed, first-class, postage paid, to Wells Fargo Home Mortgage, Inc.,

Indenture Trustee shall be in writing, personally delivered or mailed

      Section 11.05. Notices and Reports to Noteholders; Waiver of Notices.

      Where this Indenture provides for notice to Noteholders of any event or
the mailing of any report to Noteholders, such notice or report shall be
sufficiently given (unless otherwise herein expressly provided) if mailed,
first-class postage prepaid, to each Noteholder affected by such event or to
whom such report is required to be mailed, at the address of such Noteholder as
it appears on the Note Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice or the mailing
of such report. In any case where a notice or report to Noteholders is mailed in
the manner provided above, neither the failure to mail such notice or report,
nor any defect in any notice or report so mailed, to any particular Noteholder
shall affect the sufficiency of such notice or report with respect to other
Noteholders, and any notice or report that is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided.

      Where this Indenture provides for notice in any manner, such notice may be
waived in writing by any Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Noteholders shall be filed with the Indenture Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      In case, by reason of the suspension of regular mail service as a result
of a strike, work stoppage or similar activity, it shall be impractical to mail
notice of any event to Noteholders when such notice is required to be given
pursuant to any provision of this Indenture, then any manner of giving such
notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a
sufficient giving of such notice.

      Section 11.06. Rules by Indenture Trustee.

      The Indenture Trustee may make reasonable rules for any meeting of
Noteholders.

      Section 11.07. Conflict With Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with another
provision hereof that is required to be included in this Indenture by any of the
provisions of the TIA, such required provision shall control.

      All covenants and agreements in this Indenture by the Issuer shall bind

      In case any provision in this Indenture or in the Notes shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

      Section 11.11. Benefits of Indenture.

      Nothing in this Indenture or in the Notes, expressed or implied, shall
give to any Person, other than the parties hereto and their successors
hereunder, any separate trustee or Co-trustee appointed under Section 6.14 and
the Noteholders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

      Section 11.12. Legal Holidays.

      In any case where the date of any Distribution Date, Redemption Date or
any other date on which principal of or interest on any Note is proposed to be
paid shall not be a Business Day, then (notwithstanding any other provision of
the Notes or this Indenture) payment need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if
made on the nominal date of any such Distribution Date, Redemption Date or other
date for the payment of principal of or interest on any Note and no interest
shall accrue for the period from and after any such nominal date, provided such
payment is made in full on such next succeeding Business Day.

      Section 11.13. Governing Law.

      IN VIEW OF THE FACT THAT NOTEHOLDERS ARE EXPECTED TO RESIDE IN MANY STATES
AND OUTSIDE THE UNITED STATES AND THE DESIRE TO ESTABLISH WITH CERTAINTY THAT

compliance with any Opinion of Counsel delivered pursuant to Section 2.11(c) or

employee or agent of the Indenture Trustee or the Owner Trustee in its
individual capacity, any holder of a beneficial interest in the Issuer, the
Owner Trustee or the Indenture Trustee or of any successor or assign of the
Indenture Trustee or the Owner Trustee in its individual capacity, except as any

liable, to the extent provided by applicable law, for any unpaid consideration
for stock, unpaid capital contribution or failure to pay any installment or call
owing to such entity. For all purposes of this Indenture, in the performance of
any duties or obligations of the Issuer hereunder, the Owner Trustee shall be
subject to, and entitled to the benefits of, the terms and provisions of the
Trust Agreement.

Securities Corporation or the Issuer, (b) file an appropriate memorandum of
points and authorities or other brief in support of such objection, or (c)

      Section 11.18. Inspection.

      The Issuer agrees that, on reasonable prior notice, it will permit any
representative of the Indenture Trustee, during the Issuer's normal business
hours, to examine all of books of account, records, reports and other papers of
the Issuer, to make copies and extracts therefrom, to cause such books to be
audited by Independent Accountants selected by the Indenture Trustee and to
discuss its affairs, finances and accounts with its officers, employees and
Independent Accountants (and by this provision the Issuer hereby authorizes its
Accountants to discuss with such representatives such affairs, finances and
accounts), all at such reasonable times and as often as may be reasonably
requested. Any expense incident to the exercise by the Indenture Trustee of any
right under this Section 11.18 shall be borne by the Issuer.

nonusurious rate of interest allowed by the applicable laws of the United States
or the State of New York (whichever shall permit the higher rate), that could
lawfully be contracted for, charged or received (the "Highest Lawful Rate"). In
the event any payment of interest on any Note exceeds the Highest Lawful Rate,
the Issuer stipulates that such excess amount will be deemed to have been paid
as a result of an error on the part of both the Indenture Trustee, acting on
behalf of the Holder of such Note, and the Issuer, and the Holder receiving such
excess payment shall promptly, upon discovery of such error or upon notice
thereof from the Issuer or the Indenture Trustee, refund the amount of such
excess or, at the option of the Indenture Trustee, apply the excess to the
payment of principal of such Note, if any, remaining unpaid. In addition, all
sums paid or agreed to be paid to the Indenture Trustee for the benefit of
Holders of Notes for the use, forbearance or detention of money shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such Notes.

      IN WITNESS WHEREOF, the Issuer and the Indenture Trustee and the have
caused this Indenture to be duly executed by their respective officers thereunto
duly authorized, all as of the day and year first above written.

   WELLS FARGO HOME EQUITY ASSET-BACKED SECURITIES 20 -[___] TRUST HOME EQUITY
                    ASSET-BACKED NOTES, SERIES 20 - , CLASS A

Wells Fargo Home Equity Asset-Backed Securities 20 -[___] Trust, a statutory
trust organized and existing under the laws of the State of Delaware (herein
referred to as the "Issuer"), for value received, hereby promises to pay to Cede
& Co., or registered assigns, the principal sum of $___________ payable on each
Distribution Date in an amount equal to the result obtained by multiplying (i) a
fraction the numerator of which is $___________ and the denominator of which is
$_____________ (this Note's "Percentage Interest") by (ii) the aggregate amount,
if any, payable from the Note Account in respect of principal on the Notes
pursuant to the Indenture dated as of [___________], 20 , between the Issuer and
[_______________], a [________________], as Indenture Trustee (the "Indenture
Trustee"); provided, however, that the entire unpaid principal amount of this
Note shall be due and payable on the earlier of (i) the Distribution Date
occurring in [___________] 20 (the "Final Maturity Date"), (ii) the Redemption
Date, if any, pursuant to Article X of the Indenture or (iii) the date on which
an Event of Default shall have occurred and be continuing, if the Notes have
been declared to be immediately due and payable in the manner provided in
Section 5.02 of the Indenture. Capitalized terms used but not defined herein are
defined in Article I of the Indenture.

<PAGE>

      Pursuant to the terms of the Indenture, payments will be made on the 25th
day of each month or, if such day is not a Business Day, on the Business Day
immediately following such 25th day (each a "Distribution Date"), commencing on
the first Distribution Date specified above, to the Person in whose name this
Note is registered at the close of business on the applicable Record Date, in an
amount equal to the product of (a) the Percentage Interest evidenced by this
Note and (b) the sum of the amounts to be paid on Notes with respect to such
Distribution Date, all as more specifically set forth in the Indenture.

      Notwithstanding the foregoing, in the case of Definitive Notes, upon
written request at least five days prior to the related Record Date with
appropriate instructions by the Holder of this Note (holding an aggregate
initial Principal Balance of at least $1,000,000), any payment of principal or
interest, other than the final installment of principal or interest, shall be
made by wire transfer to an account in the United States designated by such
Holder reasonably satisfactory to the Indenture Trustee.

      Payments of principal and interest on the Notes will be made on each
Distribution Date to Noteholders of record as of the related Record Date. On
each Distribution Date, Noteholders will be entitled to receive interest
payments in an aggregate amount equal to the related Note Interest for such
Distribution Date, together with principal payments in an aggregate amount equal
to the Monthly Principal plus, until the Overcollateralization Amount is equal
to the Targeted Overcollateralization Amount, Excess Cash, if any, for such
Distribution Date. The "Principal Balance" of a Note as of any date of
determination is equal to the initial principal balance thereof as of the
Closing Date, reduced by the aggregate of all amounts previously paid with
respect to such Note on account of principal.

      The principal of and interest on this Note are payable in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts. All payments made by the Issuer
with respect to this Note shall be applied first to interest due and payable on
this Note as provided above and then to the unpaid principal of this Note.

      This Note is one of a duly authorized issue of Notes of the Issuer,
designated as its Asset Backed Notes, Series 20 - , Class A, issued under the
Indenture, to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights and obligations
thereunder of the Issuer, the Indenture Trustee and the Holders of the Notes. To
the extent that any provision of this Note contradicts or is inconsistent with
the provisions of the Indenture, the provisions of the Indenture shall control
and supersede such contradictory or inconsistent provision herein. The Notes are
subject to all terms of the Indenture.

      The Notes are and will be equally and ratably secured by the Mortgage
Loans and the other collateral related thereto pledged as security therefor as
provided in the Indenture.

      As described above, the entire unpaid principal amount of this Note shall
be due and payable on the earlier of the Final Maturity Date and the Redemption
Date, if any, pursuant to Article X of the Indenture. Notwithstanding the
foregoing, the entire unpaid principal amount of the Notes shall be due and
payable on the date on which an Event of Default shall have occurred and be
continuing if the Indenture Trustee, at the direction of the Holders of the
Notes

                                      A-2
<PAGE>

representing not less than 50% of the Principal Balance of the Outstanding
Notes, shall have declared the Notes to be immediately due and payable in the
manner provided in Section 5.02 of the Indenture. All principal payments on the
Notes shall be made pro rata to the Noteholders entitled thereto.

      The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Fund which
constitutes security for the payment of the Notes. The assets included in the
Trust Fund will be sole source of payments on the Notes, and each Holder hereof,
by its acceptance of this Note, agrees that (i) such Note will be limited in
right of payment to amounts available from the Trust Fund as provided in the
Indenture and (ii) such Holder shall have no recourse to the Issuer, the Owner
Trustee, the Indenture Trustee, the Depositor, the Securities Administrator, the
Seller, the Servicer or any of their respective affiliates, or to the assets of
any of the foregoing entities, except the assets of the Issuer pledged to secure
the Notes pursuant to the Indenture.

      Payments of interest on this Note due and payable on each Distribution
Date, together with the installment of principal, if any, to the extent not in
full payment of this Note, shall be made by check mailed to the Person whose
name appears as the Holder of this Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on each Record Date, except that
with respect to Notes registered on the Record Date in the name of the nominee
of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will
be made by wire transfer in immediately available funds to the account
designated by such nominee. Such checks shall be mailed to the Person entitled
thereto at the address of such Person as it appears on the Note Register as of
the applicable Record Date without requiring that this Note be submitted for
notation of payment. Notwithstanding the foregoing, in the case of Definitive
Notes, upon written request at least five days prior to the related Record Date
with appropriate instructions by the Holder of this Note (holding an aggregate
initial Principal Balance of at least $1,000,000), any payment of principal or
interest, other than the final installment of principal or interest, shall be
made by wire transfer to an account in the United States designated by such
Holder reasonably satisfactory to the Indenture Trustee. Any reduction in the
principal amount of this Note (or any one or more Predecessor Notes) effected by
any payments made on any Distribution Date shall be binding upon all future
Holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. If
funds are expected to be available, as provided in the Indenture, for payment in
full of the then remaining unpaid principal amount of this Note on a
Distribution Date, then the Indenture Trustee, in the name of and on behalf of
the Issuer, will notify the Person who was the Holder hereof as of the Record
Date preceding such Distribution Date by notice mailed or transmitted by
facsimile prior to such Distribution Date, and the amount then due and payable
shall be payable only upon presentation and surrender of this Note at the
Indenture Trustee's principal Corporate Trust Office or at the office of the
Indenture Trustee's agent appointed for such purposes.

      As provided in the Indenture, the Notes may be redeemed in whole, but not
in part, at the option of the Depositor, on any Distribution Date on and after
the date on which the Principal Balance is less than 10% of the Original
Principal Balance.

      As provided in the Indenture and subject to certain limitations set forth
therein, the transfer of this Note may be registered on the Note Register upon
surrender of this Note for registration of transfer at the office or agency
designated by the Issuer pursuant to the Indenture, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Indenture Trustee duly executed by, the Holder hereof or such Holder's attorney
duly authorized in writing, with such signature guaranteed by an "eligible
guarantor institution" meeting the requirements of the Note Registrar, which
requirements include membership or participation in the Securities Transfer
Agent's Medallion Program ("STAMP") or such other "signature guarantee program"
as may be determined by the Note Registrar in addition to, or in substitution
for, STAMP, all in accordance with the Securities Exchange Act of 1934, as
amended, and thereupon one or more new Notes of authorized denominations and in
the same aggregate principal amount will be issued to the designated transferee
or transferees. No service charge will be charged for any registration of
transfer or exchange of this Note, but the transferor may be required to pay a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any such registration of transfer or exchange.

      The Note Registrar shall not register the transfer of this Note unless the
Note Registrar has received a representation letter from the transferee to the
effect that either (i) the transferee is not, and is not acquiring the Note on
behalf of or with the assets of, an employee benefit plan or other retirement
plan or arrangement that is subject to Title I of the Employee Retirement Income
Security Act or 1974, as amended, or Section 4975 of the Code or (ii) the
acquisition and holding of this Note by the transferee qualifies for exemptive
relief under a Department of Labor Prohibited Transaction Class Exemption. Each
Beneficial Owner, by acceptance of a beneficial interest herein, shall be deemed
to make one of the foregoing representations.

      Each Noteholder or Beneficial Owner, by acceptance of a Note or, in the
case of a Beneficial Owner, a beneficial interest in a Note, covenants and
agrees that no recourse may be taken, directly or indirectly, with respect to
the obligations of the Issuer, the Owner Trustee or the Indenture Trustee on the
Notes or under the Indenture or any certificate or other writing delivered in
connection therewith, against (i) the Indenture Trustee or the Owner Trustee in
its individual capacity, (ii) any owner of a beneficial interest in the Issuer
or (iii) any partner, owner, beneficiary, agent, officer, director or employee
of the Indenture Trustee or the Owner Trustee in its individual capacity, any
holder of a beneficial interest in the Issuer, the Owner Trustee or the
Indenture Trustee or of any successor or assign of the Indenture Trustee or the
Owner Trustee in its individual capacity, except as any such Person may have
expressly agreed and except that any such partner, owner or beneficiary shall be
fully liable, to the extent provided by applicable law, for any unpaid
consideration for stock, unpaid capital contribution or failure to pay any
installment or call owing to such entity.

      Each Noteholder or Beneficial Owner, by acceptance of a Note or, in the
case of a Beneficial Owner, a beneficial interest in a Note, covenants and
agrees by accepting the benefits of the Indenture that such Noteholder or
Beneficial Owner will not at any time institute against Wells Fargo Asset
Securities Corporation or the Issuer, or join in any institution against the
Wells Fargo Asset Securities Corporation or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under any
United States federal or state bankruptcy or similar law in connection with any
obligations relating to the Notes, the Indenture, the Mortgage Loan Purchase
Agreement and the Servicing Agreement (the "Basic Documents").

      The Issuer has entered into the Indenture and this Note is issued with the
intention that, for federal, state and local income, single business and
franchise tax purposes, the Notes will qualify as indebtedness of the Issuer
secured by the Trust Fund. Each Noteholder, by acceptance of a Note (and each
Beneficial Owner by acceptance of a beneficial interest in a Note), agrees to
treat the Notes for federal, state and local income, single business and
franchise tax purposes as indebtedness of the Issuer.

      Prior to the due presentment for registration of transfer of this Note,
the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture
Trustee may treat the Person in whose name this Note (as of the day of
determination or as of such other date as may be specified in the Indenture) is
registered as the owner hereof for all purposes, whether or not this Note be
overdue, and none of the Issuer, the Indenture Trustee or any such agent shall
be affected by notice to the contrary.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer with the consent of the Holders of Notes representing a
majority of the Principal Balance of all Outstanding Notes. The Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Principal Balance of Outstanding Notes, on behalf of the
Holders of all the Notes, to waive compliance by the Issuer with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note (or
any one or more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof whether
or not notation of such consent or waiver is made upon this Note. The Indenture
also permits the amendment thereof, in certain limited circumstances, or the
waiver of certain terms and conditions set forth in the Indenture, without the
consent of Holders of the Notes issued thereunder.

      The term "Issuer" as used in this Note includes any successor to the
Issuer under the Indenture.

      Initially, the Notes will be represented by one Note registered in the
name of CEDE & Co. as nominees of the Clearing Agency. The Notes will be
delivered as provided in the Indenture and subject to certain limitations
therein set forth. The Notes are exchangeable for a like aggregate initial
Principal Balance of Notes of different authorized denominations, as requested
by the Holder surrendering the same.

      THIS NOTE AND THE INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS,
AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER AND THEREUNDER
SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the

                                      A-5
<PAGE>

principal of and interest on this Note at the times, place and rate, and in the
coin or currency herein prescribed.

      Unless the certificate of authentication hereon has been executed by the
Authenticating Agent whose name appears below by manual signature, this Note
