Servicer pursuant to this Agreement shall at all times be performed in
compliance with all applicable laws.

            2.1.2. Potential Conflict. If any obligation of the Servicer
pursuant to this Agreement shall give rise to a potential conflict with
applicable law, such obligation shall be construed so as to (a) comply with all
applicable laws and (b) effectuate with respect to such obligations, to the
fullest extent permitted by law, the intention of the parties hereto as
expressed in this Agreement.

            2.1.3. Consistent Legal Compliance. The fact that certain provisions
of this Agreement contain language which expressly requires compliance with all
applicable laws, shall not give rise to an implication that other provisions,
which do not expressly include such language, operate in derogation of the
requirement for such legal compliance.

            2.1.4. General Interpretive Rules. For purposes of this Agreement,
except as otherwise expressly provided or unless the context otherwise requires,
(i) the terms defined in this Agreement have the meanings assigned to them in
this Agreement and include the plural as well as the singular, and the use of
any gender herein shall be deemed to include the other gender; (ii) reference
herein to "Article", "Section", "Clause", and other subdivisions, and to
"Exhibits", without reference to a document, are to designated Articles,
Sections, Clauses and other subdivisions of, and to Exhibits to, this Agreement;
(iii) reference to a Clause without further reference to a Section is a
reference to such Clause as contained in the same Section in which the reference
appears, and this rule shall also apply to other subdivisions; (iv) "including"
means "including but not limited to"; and (v) the words "herein", "hereof",
"hereunder" and other words of similar import refer to this Agreement as a whole
and not to any particular provision.

            2.1.5. Construction of Provisions. Although certain provisions of
this Agreement contain express language which precludes the Servicer's recovery
of, or reimbursement for, expenses incurred hereunder, no inference to the
contrary shall be drawn from absence of such, or similar, language in any other
provision hereof regarding expenses.

            Section 2.2 Servicer Practices

            2.2.1. Prudent Servicing Practices. Where not inconsistent with the
provisions of this Agreement, the Servicer shall at all times perform its
obligations hereunder in accordance with Prudent Servicing Practices, which
shall not be less exacting than the Servicer employs and exercises in servicing
and administering mortgage loans for its own account, or for the account of FNMA
or FHLMC, including exploring alternatives to foreclosure to mitigate Realized
Losses.

            2.2.2. Non-Discrimination Practices. The Servicer shall at all times
perform its obligations under this Agreement so as to (a) treat Borrowers on the

            Section 2.3 General Provisions

            2.3.1. Servicer's Agreement. The Servicer agrees with the Master

accordance with this Agreement, and (c) all obligations hereunder related
thereto are discharged.

            2.3.3. Amended Mortgage Loan Schedule. From time to time as
additional Mortgage Loans are transferred to be serviced hereunder by the
Servicer, the Servicer Mortgage Loan Schedule shall be amended by the Master
Servicer to include the new Mortgage Loans. Due to defects in documentation and
for other reasons, certain Mortgage Loans referred to in the Servicer Mortgage
Loan Schedule may be deleted and other Mortgage Loans may be added. The Servicer
hereby agrees to any such addition and/or deletion of any Mortgage Loans and, in
the event any Mortgage Loans are added and/or deleted from the Servicer Mortgage
Loan Schedule, the Servicer authorizes the Master Servicer to amend the Servicer
Mortgage Loan Schedule. The Master Servicer shall provide the Servicer with the

                                    ARTICLE 3

                                REMIC Compliance

            Section 3.1 General

            3.1.1. Applicability. The provisions of this Article 3 apply to all
the Mortgage Loans or Mortgaged Property unless the Mortgage Loan has not been
transferred (or been identified for a future transfer) to an entity with respect
to which an election to be characterized as a REMIC has been (or is expected to
be) made.

            3.1.2. Modifications of Mortgage. With the prior written consent of
the Master Servicer, the Servicer may modify the terms of a Mortgage Loan which
is in default or a Mortgage Loan as to which default is reasonably foreseeable;
provided, however, that (i) such modification may not reduce the amount of
principal owed under the related Mortgage Note or permanently reduce the
Mortgage Interest Rate for such Mortgage Loan and (ii) the Servicer and the
Master Servicer have determined that such modification is likely to increase the
proceeds of such Mortgage Loan over the amount expected to be collected pursuant
to foreclosure. Notwithstanding anything to the contrary in this Agreement, the
Servicer shall not permit any modification of any material term of a Mortgage
Loan (including the Mortgage Interest Rate, the principal balance, the
amortization schedule, or any other term affecting the amount or timing of
payments on the Mortgage Loan) where such modification is not the result of a
default or as to which default is reasonably foreseeable under the Mortgage Loan
unless the Master Servicer has consented thereto and the Servicer has received
an Opinion of Counsel or a ruling from the Internal Revenue Service (at the
expense of the Servicer or the party making the request of the Servicer to
modify the Mortgage Loan) to the effect that such modification would not be
treated as giving rise to a new debt instrument for federal income tax purposes
or a disposition of the modified Mortgage Loan and that such modification is
permitted under the REMIC Provisions.

            3.1.3. Indemnification with Respect to Certain Taxes and Loss of
REMIC Status. In the event that the REMIC fails to qualify as a REMIC, loses its
status as a REMIC, or incurs state or local taxes, or tax as a result of a
prohibited transaction or contribution subject to taxation under the REMIC
Provisions due to the negligent performance by the Servicer of its duties and
obligations set forth herein, the Servicer shall indemnify the Trustee, the
Trust Administrator (if applicable), the Master Servicer and the holders of the
related Certificates against any and all losses, claims, damages, liabilities or
expenses ("REMIC Failure Losses") resulting from such negligence; provided,
however, that the Servicer shall not be liable for any such REMIC Failure Losses
attributable to the action or inaction of the Master Servicer or the holders of
such Certificates nor for any such REMIC Failure Losses resulting from
misinformation provided by the Master Servicer on which the Servicer has relied.
The foregoing shall not be deemed to limit or restrict the rights and remedies
of the other holders of the Certificates now or hereafter existing at law or in
equity.

            Section 3.2 REO Qualification

            3.2.1. Foreclosure Property. Notwithstanding any other provision of
this Agreement, the Servicer, shall not rent, lease, or otherwise earn income on
behalf of the REMIC with respect to any REO which might cause such REO to fail
to qualify as "foreclosure" property within the meaning of section 860G(a)(8) of
the Code (e.g., rent based upon the earnings of the lessee) or result in the
receipt by the REMIC of any "income from non-permitted assets" within the
meaning of section 860F(a)(2) of the Code (e.g., income attributable to any
asset which is not a qualified mortgage, a cash flow or reserve fund investment,
or personal property not incidental to the REO) or any "net income from
foreclosure property" which is subject to tax under the REMIC Provisions unless
the Master Servicer has received an Opinion of Counsel (at the Servicer's
expense) to the effect that, under the REMIC Provisions and (where appropriate,
any relevant proposed legislation) any income generated for the REMIC by the REO
would not result in the imposition of a tax upon the REMIC. In general, the
purpose of this Section 3.2 and the REMIC Provisions (which this section is
intended to implement) is to ensure that the income earned by the REMIC is
passive type income such as interest on mortgages and passive type rental income
on real property.

            3.2.2. Foreclosure Property Qualification Restrictions. Without
limiting the generality of the foregoing, the Servicer shall not:

            (a) permit the REMIC to enter into, renew or extend any lease with
      respect to any REO, if the lease by its terms will give rise to any income
      that does not constitute Rents from Real Property;

            (b) permit any amount to be received or accrued under any lease
      other than amounts that will constitute Rents from Real Property;

            (c) authorize or permit any construction on any REO, other than the
      completion of a building or other improvement thereon, and then only if
      more than ten percent of the construction of such building or other
      improvement was completed before default on the related Mortgage Loan
      became imminent, all within the meaning of Section 856(e)(4)(B) of the
      Code; or

            (d) Directly Operate or allow any other Person to Directly Operate,
      any REO on any date more than 90 days after its acquisition date, other
      than through an "independent contractor," within the meaning of Section
      856(e) of the Code;

unless, in any such case, the Servicer has requested and received an Opinion of
Counsel (at the Servicer's expense) to the effect that such action will not
cause such REO to fail to qualify as "foreclosure property" within the meaning
of Section 860G(a)(8) of the Code at any time that it is held by the REMIC, in
which case the Servicer may take such actions as are specified in such Opinion
of Counsel.

            3.2.3. REO Disposition. Within 30 days following an REO Disposition,
the Servicer shall provide to the Master Servicer a statement of accounting for
the related REO, including without limitation, (i) the loan number of the
related Mortgage Loan, (ii) the date such Mortgaged Property was acquired in
foreclosure or by deed in lieu of foreclosure, (iii) the date of REO
Disposition, (iv) the gross sales price and related selling and other expenses,
(v) accrued interest calculated from the date of acquisition to the disposition
date and (vi) such other information as the related trustee may reasonably
request.

            Section 3.3 Prohibited Transactions and Activities

            3.3.1. Mortgage Loan Disposition Restriction. The Servicer shall not
permit the sale, disposition or substitution for any of the Mortgage Loans
(except in a disposition pursuant to (i) the foreclosure or default of a
Mortgage Loan, (ii) the bankruptcy or insolvency of the REMIC, (iii) the
termination of the REMIC in a "qualified liquidation" or "clean-up" call as
defined in Section 860F of the Code or (iv) a substitution of a Qualifying
Substitution Mortgage Loan as permitted under the REMIC Provisions), nor acquire
any assets for the REMIC, after the startup day of the REMIC, nor sell or
dispose of any investments in any of the accounts established by the Servicer
for the REMIC for gain, nor accept any contributions to the REMIC (other than
certain cash contributions permitted by Section 860G(c) of the Code) unless it
has received an Opinion of Counsel (at the expense of the Person requesting the
Servicer to take such action) to the effect that such disposition, acquisition,
substitution, or acceptance will not (a) affect adversely the status of the
REMIC as a REMIC or of the Certificates, other than the Certificates
representing the residual interest in the REMIC, as the regular interests
therein within the meaning of the REMIC Provisions, (b) affect the distribution
of interest or principal on the Certificates, (c) result in the encumbrance of
the assets transferred or assigned to the REMIC (except pursuant to the
provisions of this Agreement) or (d) cause the REMIC to be subject to a tax on
"prohibited transactions" or "prohibited contributions" pursuant to the REMIC
Provisions.

            3.3.2. Personal Property. The Servicer shall not acquire any
personal property relating to any Mortgage Loan unless either:

            (a) such personal property is incident to real property (within the
      meaning of Section 856(e)(1) of the Code) so acquired by the Servicer; or

            (b) the Servicer shall have requested and received an Opinion of
      Counsel, at the expense of the Servicer, to the effect that the holding of
      such personal property by the REMIC will not cause the imposition of a tax
      on the REMIC under the REMIC Provisions or cause the REMIC to fail to
      qualify as a REMIC at any time that any Certificate is outstanding.

            Section 3.4 Eligible Investments

            3.4.1. Custodial Account. Funds in any custodial accounts
established by the Servicer and maintained in respect of the REMIC may be
invested and, if invested, shall be invested in Eligible Investments selected by
the Servicer which shall mature not later than the Business Day immediately
preceding the next Remittance Date, and any such Eligible Investment shall not
be sold or disposed of prior to its maturity. All such Eligible Investments
shall be made in the name of the REMIC or its nominee. All income and gain
realized from any such investment shall be, as long as the Servicer is servicing
the Mortgage Loans held by the REMIC, for the benefit of the Servicer as
additional compensation and shall be subject to its withdrawal or order from
time to time. The amount of any losses incurred in respect of any such
investments shall be deposited in the relevant account by the Servicer out of
its own funds immediately as realized. The foregoing requirements for deposit in
such account are exclusive, it being understood and agreed that, without
limiting the generality of the foregoing, payments of interest on funds in such
account and, as long as the Servicer is servicing the Mortgage Loans held by the
REMIC, payments in the nature of prepayment fees, late payment charges,
assumption fees or any similar fees customarily associated with the servicing
mortgage loans paid by any mortgagor need not be deposited by the Servicer in
such account and may be retained by the Servicer as additional servicing
compensation. If the Servicer deposits in such account any amount not required
to be deposited therein, it may at any time withdraw such amount, any provision
herein to the contrary notwithstanding.

            3.4.2. Escrow Account. Subject to the terms of the related Mortgage
Notes and Security Instrument, and further subject to applicable law, any funds
in any escrow account shall be invested in Eligible Investments that mature
prior to the date on which payments have to be made out of the related escrow
account and any such Eligible Investment shall not be sold or disposed of prior
to its maturity; provided that, if any loss is incurred on any such investment,

                        communicated in connection with a sale or purchase of
                        securities, without regard to whether the Servicer

                        with or separately from such other information;

                  (ii)  any failure by the Servicer, any Subservicer or any

                        when and as required under Sections 4.1.3 and 4.1.4,
                        including any failure by the Servicer to identify

Depositor, as applicable, for all costs reasonably incurred by each such party
in order to obtain the information, report, certification, accountants' letter
or other material not delivered as required by the Servicer, any Subservicer or
any Subcontractor. If the indemnification provided for herein is unavailable to
hold harmless any Servicer Information Indemnified Party, then the Servicer
agrees that it shall contribute to the amount paid or payable by such Servicer
Information Indemnified Party as a result of the losses, claims, damages or
liabilities of such Servicer Information Indemnified Party in such proportion as
is appropriate to reflect the relative fault of such Servicer Information
Indemnified Party on the one hand and the Servicer on the other in connection

11.2.1 hereof, in a manner in which the Servicer is not relieved from liability
as described in Section 4.4.2 hereof. Each Indemnified Party shall cooperate
with the Servicer in the defense of such Claims and shall not settle any such
Claim without the prior written consent of the Servicer.

            4.5.2. Survival of Indemnity. This indemnification shall survive
purchase, transfer of any interest in a Mortgage Loan by any indemnified party,
the Liquidation of such Mortgage Loan, termination of the Servicer's servicing
rights with respect to such Mortgage Loan and termination or expiration of this
Agreement between the Servicer and the Master Servicer and its successors and
assigns.

            Section 4.6 Servicer's Compensation; Indemnification

            4.6.1. Servicing Fee Amount. In consideration of the services
rendered under this Agreement, absent default by the Servicer, the Servicer
shall on each Remittance Date be entitled to a monthly aggregate servicing
compensation (the "Monthly Servicing Compensation") for the preceding month
which shall equal the sum of (a) the Servicing Fee payable with respect to each
Mortgage Loan serviced during such month and (b) any interest earnings on each
Custodial P&I Account with respect to such month other than interest earnings
thereon which are payable to the Borrower pursuant to the Security Instrument or
applicable law, subject to any adjustment for Month End Interest as described in
Section 7.6.1. Absent default by the Servicer, the Servicer shall also be
entitled to retain in addition to the Monthly Servicing Compensation any late
charges, prepayment fees, penalty interest, assumption fees, modification fees
or deficiency recovery fees paid by the Borrower, any Liquidation Profits or any
other customary income or any payments of interest related to any Prepayment in
Full received by the Servicer prior to the Applicable Unscheduled Receipt
Period, which amounts are not required to be deposited into the Custodial P&I
Account. The Servicer shall be required to pay all expenses incurred by it in
connection with its servicing activities hereunder and shall not be entitled to
reimbursement therefor except as specifically provided for herein.

            4.6.2. Servicing Fee Source. The Servicing Fee for each Mortgage
Loan shall be payable solely from the interest portion of the related Monthly
Payment paid by the Borrower or other payment of interest paid with respect to
the Mortgage Loan, whether from the proceeds of foreclosure or any judgment,
writ of attachment or levy against the Borrower or his assets, or from funds
paid in connection with any prepayment in full or from Insurance Proceeds or
Liquidation Proceeds.

            4.6.3. Indemnification of Servicer. The Master Servicer hereby
agrees to indemnify and hold harmless the Servicer, any Subservicer appointed by
it, any of their respective directors, officers, employees or agents, or its
delegees for any action taken by the Servicer, any Subservicer or any of their
respective directors, officers, employees or agents, or its delegees or for
refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that the Servicer, any
Subservicer or any of their respective directors, officers, employees or agents,
or its delegees are not protected against any liability which would otherwise be
imposed by reason of willful misfeasance, bad faith or gross negligence in the
performance of his or its duties or by reason of reckless disregard of his or
its obligations and duties under this Agreement.

validly existing and in good standing under the laws of the state of its
incorporation and is duly qualified to do business and is in good standing under
the laws of each jurisdiction that requires such qualification wherein it owns
or leases any material properties, or in which it conducts any material business
or in which the performance of its duties under this Agreement would require
such qualification, except where the failure to so qualify would not have a
material adverse effect on (a) the Servicer's performance of its obligations
under this Agreement, (b) the value or marketability of the Mortgage Loans, or
(c) the ability to foreclose on the related Mortgaged Properties.

            5.2.2. Requisite. The Servicer has the corporate power and authority
to own its properties and conduct any and all business required or contemplated
by this Agreement and to perform the covenants and obligations to be performed
by it under this Agreement. The Servicer holds all material licenses,
certificates and permits from all governmental authorities necessary for
conducting its business as it is presently conducted.

            5.2.3. No Conflicts. The execution and delivery of this Agreement
are within the corporate power of the Servicer and have been duly authorized by
all necessary actions on the part of the Servicer; neither the execution and
delivery of this Agreement by the Servicer, nor the consummation by the Servicer
of the transactions herein contemplated, nor compliance with the provisions
hereof by the Servicer, will (i) conflict with or result in a breach of, or
constitute a default under, any of the provisions of the articles of
incorporation or bylaws of the Servicer or any law, governmental rule or
regulation, or any judgment, decree or order binding on the Servicer or any of
its properties, or any of the provisions of any indenture, mortgage, deed of

effect, and to general principles of equity.

            5.2.5. No Consents. No consent, approval, order or authorization of
any governmental authority or registration, qualification or declaration with
any such authority is required in order for the Servicer to perform its
obligations under this Agreement.

FHLMC and will remain approved as an "eligible seller/servicer" of conventional,
residential mortgage loans as provided in FNMA or FHLMC guidelines and in good

seller/servicer status or that such agencies have threatened the servicer with
revocation of its approved seller/servicer status.

            5.2.7. Financial Condition. The Servicer is not, and, with passage
of time, does not expect to become, insolvent or bankrupt. Except as disclosed
in the Prospectus, there is no material risk that the Servicer's financial

its servicing obligations under this Agreement in a manner that could have a
material impact on the performance of the Mortgage Loans or the Certificates.
The Servicer shall promptly notify the Master Servicer of any material adverse
change of its financial condition.

            5.2.8. Servicing Practices. The servicing practices used by the

with all federal, state and local laws, rules, regulations and requirements in
connection therewith and are in accordance with Prudent Servicing Practices.

            5.2.9. No Impairment. There is no action, suit, proceeding or

inquiry, threatened, against the Servicer which, either in any one instance or
in the aggregate, may result in any material adverse change in 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 which if adversely determined would affect the validity
of this Agreement or of any action taken or to be taken in connection with the
obligations of the Servicer contemplated herein, or which would be likely to
impair materially the ability of the Servicer to perform under the terms of this
Agreement.

            5.2.10. No Inquiries. The Servicer has not been the subject of an
audit by any of the Master Servicer, FHA, HUD, FDIC, FNMA, FHLMC, GNMA or any
Primary Mortgage Insurer, which audit included material allegations of failure
to comply with applicable loan origination, servicing or claims procedures, or
resulted in a request for repurchase of Mortgage Loans or indemnification in
connection with the Mortgage Loans.

            5.2.11. No Performance Triggering Event. Except as disclosed in the
Prospectus, the Servicer is not aware and has not received notice that any
default, early amortization or other performance triggering event has occurred
as to any securitization due to any act or failure to act of the Servicer under
such securitization.

            5.2.12. No Termination. Except as disclosed in the Prospectus, the
Servicer has not been terminated as servicer in a residential mortgage loan
securitization, either due to a servicing default or to application of a
servicing performance test or trigger.

            5.2.13. No Material Noncompliance. Except as disclosed in the
Prospectus or otherwise in writing provided by the Servicer to the Master
Servicer, there has been no material noncompliance with the applicable servicing
criteria with respect to securitizations of residential mortgage loans involving

            5.2.14. Servicing Policies and Procedures. Except as disclosed in
the Prospectus, no material changes to the Servicer's policies or procedures
with respect to the servicing function it will perform under this Agreement for
mortgage loans of a type similar to the Mortgage Loans have occurred during the
three-year period immediately preceding the date of this Agreement.

            5.2.15. No Affiliations. Except as disclosed in the Prospectus,
there are no affiliations, relationships or transactions relating to the
Servicer and any party identified in Item 1119 of Regulation AB of the type
described therein.

            5.2.16. Legal or Governmental Proceedings. Except as disclosed in
the Prospectus, there are no material legal or governmental proceedings pending
(or known to be contemplated) against the Servicer or any Subservicer that would
be material to Certificateholders.

Relative to the Mortgage Loans:

            5.2.17. Custodial and Escrow Accounts Current. All Custodial P&I
Accounts, Custodial T&I Accounts, Custodial Buydown Accounts and Escrow Funds
are maintained by the Servicer and have been maintained in accordance with
applicable law and the terms of the Mortgage Loans. The Escrow Items required by
the Mortgages which have been paid to the Servicer for the account of the
Borrower are on deposit in the appropriate Custodial Account. All funds received
by the Servicer in connection with the Mortgage Loans, including, without
limitation, foreclosure proceeds, Insurance Proceeds, condemnation proceeds and
principal reductions, have promptly been deposited in the appropriate Custodial
Account, and all such funds have been applied to reduce the principal balance of
the Mortgage Loans in question, or for reimbursement of repairs to the Mortgaged
Property or as otherwise required by applicable law.

            5.2.18. Insurance Maintenance. Pursuant to the terms of the related
Security Instrument, all buildings or other improvements upon the related
Mortgaged Property are insured by an insurance policy or policies meeting the
requirements of Articles 15 and 16 hereof. The related Security Instrument
obligates the Borrower thereunder to maintain the hazard insurance policy at the
Borrower's cost and expense and, upon the Borrower's failure to do so,
authorizes the Mortgagee under the related Security Instrument to obtain and
maintain such insurance at the Borrower's cost and expense and to seek
reimbursement therefor from the Borrower. 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. The
Servicer and the Borrower have not engaged in any act or omission that would
impair the coverage of any such policy, the benefits of the endorsement provided
for herein, or the validity and binding effect of either. The Mortgage Loan
Documents permit the maintenance of an escrow account to pay the premiums for
the above mentioned insurance, and the requirement for such escrows has not been
waived, unless otherwise required by applicable state law.

                                    ARTICLE 6

                              Custodial Accounting

            Section 6.1 In General

            6.1.1. Custodial Account Establishment. The Servicer must establish
appropriate custodial accounts for the benefit of the Trustee, its successors
and assigns for the deposit of funds collected in connection with such Mortgage
Loans. All custodial accounts and related records must be maintained in
accordance with sound and controlled accounting practices. The custodial
accounts maintained pursuant to this Agreement may be custodial accounts for one
or more other series of mortgage pass-through certificates issued by Wells Fargo
Asset Securities Corporation; provided, however, that (a) the trustee for such
other series under the related pooling and servicing agreement(s) is the Trustee
and (b) the master servicer for such other series under the related pooling and
servicing agreement(s) is the Master Servicer.

            6.1.2. Custodial Account Separateness. (a) At least one custodial
account for principal and interest (i.e., a Custodial P&I Account), one
custodial account for taxes and insurance (i.e., a Custodial T&I Account), one
custodial account for Subsidy Funds, if applicable (i.e., a Custodial Subsidy
Account) and one custodial account for Buydown Funds, if applicable (i.e., a
Custodial Buydown Account), shall be established and maintained for the Mortgage
Loans. Except as specified in 6.1.2(b), without the written consent of the
Master Servicer, funds in these accounts may not be commingled with other funds
held by the Servicer. Each Custodial P&I Account shall be established as an
Eligible Account ("Eligible Custodial P&I Account").

            (b) Notwithstanding anything to the contrary elsewhere in this
      Agreement, the Servicer may employ the Custodial T&I Account as the
      Custodial Subsidy Account and/or the Custodial Buydown Account to the
      extent that the Servicer can separately identify any Subsidy Funds or
      Buydown Funds, as applicable, deposited therein.

            6.1.3. Custodial Account Maintenance. The Servicer must ensure that
each Custodial P&I Account, Custodial T&I Account, Custodial Subsidy Account and
Custodial Buydown Account meets the following guidelines:

            (a) the accounts must be Eligible Accounts;

            (b) the name of each Custodial P&I Account, Custodial T&I Account
      and Custodial Buydown Account shall include a reference to the name of the
      Trustee and the designation of the series of Mortgage Pass-Through
      Certificates or, where such accounts are accounts maintained for multiple
      series of mortgage pass-through certificates as described in Section
      6.1.1, a reference to "HSBC Bank USA, National Association, as trustee for
      Wells Fargo Asset Securities Corporation, Mortgage Pass-Through
      Certificates;"

            (c) the Servicer must transfer all funds on hand relating to such
      Mortgage Loans, Monthly Payments due on or after the related Cut-Off Date
      and any principal prepayments received after the related Cut-Off Date,
      into the appropriate custodial accounts meeting the requirements of
      Sections 6.1.1 and 6.1.2 hereof;

            (d) beginning with any payment due on or after the related Cut-Off
      Date, all collections on the Mortgage Loans must be credited to the
      appropriate custodial account no later than the second Business Day
      following receipt;

            (e) (i) the Servicer shall not permit the balance of any Custodial
      P&I Account to exceed the Threshold Amount or include any amounts then
      required to be remitted to the Certificate Account pursuant to Section
      18.3.1, (ii) in the event the Servicer collects amounts in excess of the
      Threshold Amount prior to the next scheduled transfer of funds to the
      respective Certificate Account, the Servicer must transfer the excess
      funds directly to the related Certificate Account by wire before the close
      of business on any day on which the amount on deposit in such account
      exceeds the Threshold Amount and (iii) in the event that the Servicer
      fails to transfer the funds in excess of the Threshold Amount to the
      related Certificate Account or to remit to the Certificate Account the
      Monthly Remittance on the Remittance Date pursuant to Section 18.3.1, the
      Master Servicer is authorized to debit such Custodial P&I Account and
      transfer such amounts to the related Certificate Account;

            (f) (i) the Servicer must file with the Master Servicer the
      appropriate ACH Debit Form for each Custodial P&I Account; (ii) the Master
      Servicer may monitor the principal balance of each Custodial P&I Account
      and may issue an ACH debit for amounts on deposit in any such account in
      excess of the Threshold Amount or otherwise in violation of Section
      6.1.3(e); (iii) such amounts will immediately be deposited into the
      appropriate Certificate Account; and (iv) the ability of the Master
      Servicer to withdraw and remit such funds to the appropriate Certificate
      Account does not relieve the Servicer of its obligations to remit such
      funds to the related Certificate Account;

            (g) upon the establishment of a Custodial P&I Account, Custodial T&I
      Account or Custodial Buydown Account, the Servicer shall promptly advise
      the Master Servicer in writing of, or of any change in, the name and
      address of the depository, the account number and the title of the
      account; and

            (h) (i) establishment and maintenance of the Custodial P&I Account,
      Custodial T&I Account and Custodial Buydown Account will be an expense of
      the Servicer; (ii) such custodial accounts may be interest-bearing
      accounts provided that such accounts comply with all local, state and
      federal laws and regulations governing interest-bearing accounts and, in
      the case of a Custodial T&I Account or Custodial Buydown Account,
      governing Borrower escrow accounts; and (iii) the Servicer must ensure
      that all interest credited to any custodial account that is not due the
      Borrower is removed by the Servicer within 30 days after receipt of such
      interest.

            6.1.4. Escrow Investment. If the Servicer elects or is required by
law to deposit the Borrower's Escrow Funds into an interest-bearing custodial
account, the Servicer shall either (a) deposit such funds into an account which
permits withdrawal on demand so as to pay Escrow Items as they come due, or (b)
invest such funds in an Eligible Account so that adequate funds mature the
Business Day prior to the date payment is due for each Escrow Item.

            6.1.5. Clearing Account. If the Servicer finds it necessary to use a
clearing account, the following guidelines must be followed:

            (a) the titles of such accounts must reflect that they are custodial
      in nature, and the depository in which the accounts are maintained must be
      informed in writing that the accounts are custodial accounts;

            (b) a check drawn on or funds transferred from a Custodial P&I
      Account or Custodial T&I Account must be deposited to a disbursement
      clearing account before or at the same time as any checks on the clearing
      account are issued;

            (c) a single clearing account must not be utilized both as a
      collection and disbursement clearing account;

            (d) the accounts must be held at depository institutions in which
      accounts are insured by the FDIC, through either the BIF or SAIF;

            (e) the Servicer must maintain adequate records and audit trails to
      support all debits and credits of each Borrower's payment records and
      accounts; and

            (f) collections deposited to a depository clearing account must be
      credited to the appropriate custodial account no later than one Business
      Day following receipt by the Servicer.

            6.1.6. Custodial Buydown Account. The Servicer must establish a
separate custodial account to hold Buydown Funds on Mortgage Loans being
serviced for the Trustee, its successors and assigns. These accounts must be
clearly marked to indicate that the Servicer is a custodian for Buydown Funds
being held for the Trustee, its successors and assigns.

            6.1.7. Certificate Account. The Master Servicer shall establish a
segregated Certificate Account in accordance with Section 3.01 of the Pooling

      deficit balance in the related Borrower's Escrow Funds.

            6.3.2. Permissible Withdrawals. With respect to each related
Borrower, the Servicer may make withdrawals from each respective Custodial T&I
Account to the extent of the balance of such related Borrower's Escrow Funds for
the following:

            (a) timely payment of such related Borrower's taxes and insurance
      premiums;

            (b) refunds to such related Borrower of excess Escrow Funds
      collected from such Borrower;

            (c) recovering T&I Advances made with respect to such related
      Borrower by the Servicer;

            (d) payment of interest, if required, to such related Borrower on
      his Escrow Funds;

            (e) removal of any deposits made in error;

            (f) to transfer payment on account of Buydown Funds and/or Subsidy
      Funds to the Custodial P&I Account; and

            (g) termination of the account.

            6.3.3. Account Requirements. Each Custodial T&I Account is to be
designated in the name of the Servicer acting as an agent for the individual
related Borrowers to make such Escrow Item payments in order to show that the
account is custodial in nature. The Servicer is required to keep records
identifying each Borrower's payment deposited into the account.

            6.3.4. Account Balance. The Servicer must never allow any Custodial
T&I Account to become overdrawn as to any individual related Borrower. If there
are insufficient funds in the account, the Servicer must advance its own funds
to cure the overdraft.

            Section 6.4 Eligible Account Investments

            6.4.1. Eligible Investments Permitted .Unless prevented or
restricted by written notice of the Master Servicer pursuant to Section 6.4.5
hereof, the Servicer may, from time to time, withdraw funds from a Custodial P&I
Account, Custodial Subsidy Account or Custodial Buydown Account, and immediately
invest such funds in Eligible Investments in accordance with this Agreement.
Upon the maturity of such Eligible Investments, such funds shall be redeposited
into the Eligible Account from which they were drawn or into the Certificate
Account.

            6.4.2. Eligible Investment Restrictions. No Eligible Investment
shall be sold or disposed of at a gain prior to maturity unless the Servicer has
obtained the consent of the Master Servicer.

            6.4.3. Eligible Investment Income. All income (other than any gain
from a sale or disposition of the type referred to in Section 6.4.2 hereof)
realized from any such Eligible Investment shall be for the benefit of the
Servicer as additional servicing compensation.

            6.4.4. Eligible Investment Losses. The amount of any losses incurred
in respect of any investments permitted under this Section 6.4 shall be
deposited in the Certificate Account by the Servicer out of its own funds
immediately as realized. The Master Servicer may, in its reasonable discretion,
from time to time, require the Servicer to provide a reasonable amount of
security to cover the risk of such investment losses. To the extent that the
Servicer shall not immediately deposit the amount of such losses in the
Certificate Account, the Master Servicer may immediately act against such
security as well as pursue all other remedies permitted by law.

            6.4.5. Eligible Investments Reports. The Servicer shall, at any time
provide such information and reports regarding its Eligible Investments under
this Agreement as the Master Servicer may request.

            6.4.6. Inter-Company Uses of Funds .Notwithstanding anything herein
to the contrary, and subject to the proviso set forth below, the Servicer is
permitted to withdraw funds from a Custodial P & I Account and commingle such
funds with the general assets of the Servicer to be used for general corporate
purposes until such time as such funds are required to be remitted to the
related Certificate Account; provided, however, that the provisions of this
Section 6.4.6 shall be applicable only for so long as (i) a master guarantee
substantially in the form of Exhibit A attached hereto has been issued by Wells
Fargo & Company for the benefit of the certificateholders of the Mortgage
Pass-Through Certificates and is currently in force and (ii) the short-term debt
or long-term debt of Wells Fargo & Company is rated by each of the Rating
Agencies in its highest short-term or highest long-term rating category or in
such lower rating category as would not result in a downgrading or withdrawing
of the rating then assigned to any of the Mortgage Pass-Through Certificates by
either Rating Agency or result in any of such rated Mortgage Pass-Through
Certificates being placed on credit review status by either Rating Agency.

                            Mortgage Loan Accounting

            Section 7.1 In General

            7.1.1. Mortgage Loan Accounting Practices. The Servicer shall
administer the application and accounting of payments made on the Mortgage Loans
in accordance with the provisions of this Agreement.

            7.1.2. Record Keeping. The Servicer must maintain complete and
accurate records of all transactions affecting any Mortgage Loan. Each Mortgage
Loan must be clearly marked to indicate that it is being serviced for the
Trustee, its successors and assigns.

            7.1.3. Record Review. The Master Servicer and its designee have the
right to:

            (a) conduct reviews and audits of the Servicer's records and
      operating procedures during any Business Day; and

            (b) examine the Servicer's financial records, the Borrowers' Escrow
      Funds records and any and all other relevant documents and materials,
      whether held by the Servicer or by another on behalf of the Servicer, to
      ensure compliance with terms and conditions of this Agreement and the
      Master Servicer's standards.

            Section 7.2 Mortgage Loan Records

            7.2.1. Account Records. Permanent Mortgage Loan account records must
be maintained by the Servicer for each Mortgage Loan. Each account record must
be identifiable by the Servicer Loan Number.

            7.2.2. Account Record Information. The Servicer shall maintain the
following information for each Mortgage Loan in a readily accessible form:

            (a) the Master Servicer Loan Number;

            (b) the current Unpaid Principal Balance;

            (c) the date of receipt, amount of payment and distribution of such
      payment for each Monthly Payment received with respect to such Mortgage
      Loan as to each related Due Date;

            (d) for ARM Loans, the current Mortgage Interest Rate, all
      limitations contained in the Mortgage Note with respect to periodic
      adjustments in the Mortgage Interest Rate, the scheduled Interest
      Adjustment Dates, Payment Adjustment Dates, the Gross Margin and the
      Index;

            (e) other transactions affecting the amounts due from or payable to
      the related Borrower;

            (f) the current outstanding balances of principal and interest
      deposits, advances, taxes and insurance deposits and unapplied payments
      with respect to such Mortgage Loan;

            (g) any overdraft of the Borrower's Escrow Funds;

            (h) any servicing reports or loan histories; and

            (i) any other information customarily maintained by a mortgage loan
      servicer of one to four family residential mortgages.

            7.2.3. Accounting Practice. Except as otherwise provided herein, all
Mortgage Loan account records must be maintained according to (a) the Uniform
Single Attestation Program for Mortgage Bankers and (b) where applicable, sound
and generally accepted accounting practices.

            7.2.4. Access to Certain Documentation and Information Regarding the
Mortgage Loans At the request of the Master Servicer, the Servicer shall provide
to the Master Servicer, the Office of Thrift Supervision, the FDIC and the
supervisory agents and examiners of the Office of Thrift Supervision and the
examiners of the FDIC, as appropriate, access to the documentation regarding the
Mortgage Loans required by applicable regulations of the Office of Thrift
Supervision or the FDIC, such access being afforded without charge but only upon
reasonable request and during normal business hours at the offices of the
Servicer designated by it. The Servicer shall permit such representatives to
photocopy any such documentation and shall provide equipment for that purpose at
a charge reasonably approximating the cost of such photocopying to the Servicer.

            Section 7.3 Accounting Procedures

            7.3.1. Principal and Interest Computation. All Mortgage Loans must
amortize with interest calculated and paid in arrears. Under this method, the
interest due from a Borrower on a Due Date is calculated based on (a) the Unpaid
Principal Balance of the related Mortgage Loan prior to application of the
principal portion of the related current Monthly Payment, (b) thirty days
interest at the related Mortgage Interest Rate and (c) adjusted as herein
provided for the effects of Curtailments, Partial Liquidation Proceeds,
Prepayments in Full and Liquidations. The calculated interest portion is then
subtracted from the related Monthly Payment to obtain the principal portion. The
principal portion is then applied to the Unpaid Principal Balance of the related
Mortgage Loan. The amount to be applied to interest for a multiple installment
must be calculated using the Unpaid Principal Balance of the related Mortgage
Loan remaining after the previous interest calculation and principal
application.

            7.3.2. Amortization Requirement. The amortization of each Mortgage
Loan must reduce to zero, or as to Balloon Loans, the respective Balloon Amount,
at the end of the Mortgage Loan term through the application of regular monthly
payments. Capitalization of interest is not permitted, except as provided by the
terms of any Mortgage Loan that provides for negative amortization.

            7.3.3. Negative Amortization. To the extent any Mortgage Loan
provides for negative amortization, such as a GPM or GPARM Loan, the Servicer
must assure that the Unpaid Principal Balance of such Mortgage Loan never
exceeds the related Maximum Negative Amortization Amount, and that the related
Monthly Payment is recast as provided for in the Mortgage Note such that the
balance fully amortizes within the remaining term of such Mortgage Loan.

            7.3.4. Interest Calculations. Monthly interest calculations for
periods of a full month must be based on a 30-day month and a 360-day year.
Factors used for such calculations should be carried to a minimum of three
decimal places. The dollar amount of any interest payment shall be carried out
to a minimum of three decimal places. Interest calculations for a period of less
than a full month must be based on a 365-day year.

            7.3.5. Buydown Loans. The Servicer must amortize a Mortgage Loan for
which Buydown Funds are applied at the Mortgage Interest Rate, not at the
buy-down rate, in order to ensure that payments are collected to amortize
properly the Mortgage Loan.

            Section 7.4 Application Procedure

            7.4.1. Application Priority. A payment from a Borrower will normally
consist of interest, principal, deposits for insurance and taxes and late
charges, if applicable. Payments received from Borrowers must be applied in the
order provided for in the related Security Instrument. To the extent not
inconsistent with the related Security Instrument, such payments shall be
applied in the following order:

            (a) required monthly interest;

            (b) required monthly principal;

            (c) deposits for taxes and insurance;

            (d) prepayment charges; and

            (e) any fees which may be retained by the Servicer, including late
      charges, returned check fees, and assumption fees.

            7.4.2. [Reserved].

            7.4.3. Advance Payments. Payments made by the Borrower to satisfy
future installments must be accounted for as prepaid installments of principal
and interest. The Servicer should contact the Borrower if there is a question
about the Borrower's intention in making any unscheduled payment.

            Section 7.5 Curtailments

            7.5.1. Curtailment Amount. The Servicer may accept Curtailments at
any time. If a Mortgage Loan is delinquent, funds received must first be applied
to bring the Mortgage Loan current. If there are excess funds after the
application of amounts received from the Borrower to pay the related Monthly
Payment, the excess funds represent a Curtailment and may be applied as a
partial principal prepayment.

            7.5.2. Curtailment Application. If a Curtailment is received on or
after the Due Date, the Servicer may either (i) retroactively apply the
Curtailment to the Scheduled Principal Balance of the related Mortgage Loan as
of the Due Date, or (ii) to the extent permitted by law and the Mortgage Loan,
apply such Curtailment at the end of the current period. The interest portion of
the next installment due is then calculated based on the Unpaid Principal
Balance of the related Mortgage Loan after application of the Curtailment.

            7.5.3. Effect of Curtailment. A Curtailment may not be used to
reduce the related Mortgage Interest Rate for any Mortgage Loan or to postpone
the Due Date of any payment.

            7.5.4. Curtailment Transmission. Each Curtailment must be deposited
into the related Custodial P&I Account within one Business Day after receipt and
must be remitted no later than the regularly scheduled Monthly Remittance to the
related Certificate Account.

            Section 7.6 Liquidations

            7.6.1. Month End Interest. If a Prepayment in Full of a Mortgage
Loan occurs, such prepayment is received by the Servicer after the Applicable
Unscheduled Receipt Period ending in the month in which such prepayment occurs,
and the Servicer does not receive a full 30 days of interest (calculated on a
30-day month, 360-day year basis) on the prepaid amount for the month in which
such Prepayment in Full occurs, the Servicer must pay the Month End Interest on
all such Mortgage Loans so prepaid in full on the Remittance Date in the month
following the month of such prepayment. Any Month End Interest Shortfall for any
month shall not be recoverable from the Servicer or any other source in the
future. The payment of Month End Interest by the Servicer, as provided for
above, shall not be an "advance" and shall not be reimbursable from the proceeds
of any Mortgage Loan.

            7.6.2. Liquidation Reports. The Servicer will report information
with respect to Liquidations in the monthly reports delivered to the Master
Servicer by the eighteenth calendar day of each succeeding month.

            7.6.3. Deposit of Funds. Within one day after the Liquidation of a
Mortgage Loan, the Servicer shall deposit the related Liquidation Proceeds
together with the related Month End Interest into the related Custodial P&I
Account.

            7.6.4. Document Request. After any Liquidation, the Servicer must
complete and send a Request for Release of Documents to the Custodian to ensure
the release of documents within the period required by applicable state law.

            Section 7.7 Realized Losses

            7.7.1. Liquidation Realized Loss Determination. With respect to the
calculation of a Realized Loss suffered on the related Mortgage Loan on a
Liquidation of such Mortgage Loan, the amount of such Realized Loss is equal to
(a) the sum of:

            (i)   Unpaid Principal Balance;

            (ii)  unpaid interest accrued at the related Mortgage Interest Rate;

            (iii) attorneys' fees and other foreclosure and sale expenses;

            (iv)  unpaid taxes;

            (v)   unpaid property maintenance expenses;

            (vi)  unpaid insurance premiums; and

            (vii) hazard loss expenses;

      less the sum of:

            (i)   the balance of Escrow Funds, if any;

            (ii)  any refund of any Hazard Insurance premium;

            (iii) rental income receipts;

            (iv)  Insurance Proceeds or PMI Advances;

            (v)   cash proceeds of any foreclosure sale;

            (vi)  proceeds from sale of a REO; and

            (vii) any amounts received pursuant to bankruptcy or insolvency
                  proceedings.

            7.7.2. Bankruptcy Realized Loss Determination. With respect to the
calculation of a Realized Loss on a Mortgage Loan subject to a Deficient
Valuation, the amount of the Realized Loss is the difference between the Unpaid
Principal Balance of the related Mortgage Loan immediately prior to the
Deficient Valuation and the Unpaid Principal Balance as reduced by the Deficient
Valuation.

            7.7.3. Reporting Requirement. As to any defaulted Mortgage Loan, the
Servicer must account to, and report in writing to, the Master Servicer as to
any Realized Loss (or gain) upon the Liquidation or Deficient Valuation in
respect of such Mortgage Loan.

            7.7.4. Servicer's Liability. Except in the case of a purchase by the
Servicer of a Mortgage Loan from the Trustee thereof due to a breach of a
representation or warranty by the Servicer or failure to perform the servicing
procedures as set forth in this Agreement, the Servicer is not liable for any
Realized Loss on any Mortgage Loan.

                                    ARTICLE 8

                                    ARM Loans

            Section 8.1 ARM Loan Servicing

            8.1.1. In General. It is the Servicer's responsibility to enforce
each ARM Loan (and any other Mortgage Loan) according to its terms and in
conformity with all applicable law. The Servicer's records must, at all times,
reflect the then-current Mortgage Interest Rate and Monthly Payment for such ARM
Loan and the Servicer must timely notify the Borrower of any changes to the
Mortgage Interest Rate and/or the Borrower's Monthly Payment.

            8.1.2. Servicer's Liability. If the Servicer fails to make either a
timely or accurate adjustment to the Mortgage Interest Rate or Monthly Payment
for an ARM Loan or to notify the Borrower of such adjustments, and subsequently
receives a short Monthly Payment, the Servicer must pay from its own funds any
shortage until the Servicer has made the necessary corrections in conformance
with applicable law so as to secure the correct Monthly Payment from the
Borrower. In the event that such error results in the Borrower making a Monthly
Payment in excess of the amount which he should have made if such adjustment
were properly calculated, then the Servicer shall promptly (a) make the required
adjustment to the Borrower's Monthly Payment and Mortgage Interest Rate so that
they reflect the amounts as properly calculated as of the related Payment
Adjustment Date, (b) refund to the Borrower the amount of any such excess
received by the Servicer from the related Payment Adjustment Date and (c) deduct
from the respective Custodial P&I Account or the Certificate Account the amount
of such refund to reimburse the Servicer for making such refund. Any amounts
paid by the Servicer pursuant to this Section shall not be an advance and shall
not be reimbursable from the proceeds of any Mortgage Loan.

            8.1.3. Adjustment Reports. All Mortgage Interest Rate and Monthly
Payment adjustments must be reported to the Master Servicer in a ARM Loan change
report.

            8.1.4. Substitute Index. If the Index required to be used to
determine the Mortgage Interest Rate for a Mortgage Loan is not available on an
Interest Adjustment Date, the Servicer, will select an index that is based on
comparable information, over which the Servicer has no control and that is
readily verifiable.

            Section 8.2 Notice of Periodic Adjustment

            8.2.1. Notice Requirement. The Notice of Periodic Adjustment is the
legal and official announcement to the Borrower of an ARM Loan of a change in
the Mortgage Interest Rate or the Monthly Payment. The Servicer must send this
notice to the Borrower, as stated in the related Mortgage Note and in accordance
with applicable law, and at least 25 days before each Payment Adjustment Date.

            8.2.2. Notice Contents. Each Notice of Periodic Adjustment
pertaining to an ARM Loan shall meet the requirements and specifications of the
Security Instrument, the Mortgage Loan, and applicable federal or state laws or
regulations.

            Section 8.3 ARM Loan Conversion

            8.3.1. Servicer's Determination. In the event a Borrower with a
convertible ARM Loan exercises its option to convert such Mortgage Loan to a
fixed interest rate, the Servicer will determine whether the conditions and
qualifications for conversion have been met and determine the fixed rate to be
applied to such Mortgage Loan pursuant to the terms of the related Mortgage
Note.

            8.3.2. Purchase by Servicer. The Servicer shall purchase such
Converted Mortgage Loan from the applicable Trustee at the Purchase Price by
depositing the Purchase Price into the Custodial P&I Account.

                                    ARTICLE 9

                               Mortgage Loan Files

            Section 9.1 Owner Mortgage Loan Files and Retained Mortgage Loan
Files

            9.1.1. Owner Mortgage Loan File and Retained Mortgage Loan File
Requirements. For each Mortgage Loan, the Master Servicer shall ensure that the
Custodian will maintain an Owner Mortgage Loan File on behalf of the Trustee
that contains each of the documents or instruments specified in Section 2.01(a)
of the Pooling and Servicing Agreement.

            For each Mortgage Loan after a Document Transfer Event, the Servicer
shall deliver to the Custodian the Retained Mortgage Loan File that contains
each of the documents or instruments specified in Section 2.01(b) of the Pooling
and Servicing Agreement and the Custodian will maintain such Retained Mortgage
Loan File on behalf of the Trustee.

            9.1.2. Custodian .If the original Security Instrument or the
Assignment from the respective prior owner of the related Mortgage Loan to the
Trustee or, if applicable, to the Trust Administrator, on behalf of the Trustee,
has not been delivered to the Custodian on the date of the transfer of ownership
of such Mortgage Loan to the Trustee because it is in the process of being
recorded, the Servicer shall, within five Business Days after its receipt of the
original recorded document, deliver it to the Custodian. The Servicer shall
promptly deliver to the Custodian any other Mortgage Loan Document to be
included in an Owner Mortgage Loan File, charged to the custody of the
Custodian, that comes into Servicer's possession.

            9.1.3. Release of Documents from Owner Mortgage Loan File or
Retained Mortgage Loan File. In the event any document contained in an Owner
Mortgage Loan File or, after the Document Transfer Event, a Retained Mortgage
Loan File, is needed by the Servicer for the proper servicing of a Mortgage
Loan, the Servicer must send to the Trustee or the Custodian, as the case may
be, two copies of a Request for Release as defined in the Pooling and Servicing
Agreement of documents. The Master Servicer hereby authorizes the Trustee or the
Custodian, as the case may be, to release such Owner Mortgage Loan Files or
Retained Mortgage Loan Files after receipt of such Servicer's request (i) upon
payment in full of such Mortgage Loan, (ii) when necessary for foreclosure or
(iii) for such other cause as the Master Servicer deems appropriate, in its
reasonable discretion. The Servicer shall be responsible for such Mortgage Loan
Documents while they are in its possession and will be deemed to hold such Owner
Mortgage Loan Files or Retained Mortgage Loan Files in trust for the benefit of
the Trustee. If such Mortgage Loan has not been paid in full or otherwise
liquidated, the Servicer shall promptly return such Owner Mortgage Loan Files or
Retained Mortgage Loan Files when they are no longer required. Notwithstanding
the foregoing, unless such Mortgage Loan has been liquidated or the related
Owner Mortgage Loan Files or Retained Mortgage Loan Files have been delivered to
an attorney, a public trustee or other public official in order to foreclose on
the related Mortgaged Property, all such Owner Mortgage Loan Files or Retained
Mortgage Loan Files released by the Trustee or the respective Custodian, as the
case may be, must be returned within 60 calendar days after their release.

            9.1.4. Execution by Trustee. In the event the Trustee's signature is
required on any document with respect to a Mortgage Loan for any reason,
including payment in full, assumption or foreclosure, the Servicer shall deliver
to the Trustee a written notice requesting that the Trustee execute such
documents and certifying as to the reason such documents are required. Upon
receipt of such executed documents, the Servicer shall record, file or deliver
such documents as appropriate for the proper servicing of such Mortgage Loan.

            9.1.5. Representing Party Officers' Certificate. If it is necessary
for the respective Representing Party to deliver an Officers' certificate with
respect to the existence of a Title Insurance policy or a Primary Mortgage
Insurance policy for several Mortgage Loans, the Master Servicer may consent to
the delivery of a single Officers' certificate of the respective Representing
Party for a schedule of mortgage loans in lieu of a separate Officers'
certificate for each such Mortgage Loan.

            9.1.6. Custodial Fees. The Servicer is responsible for the related
ongoing fees of each Custodian. If for any reason at any time the Master
Servicer pays custodial fees (including any payment made by the Master Servicer
pursuant to Section 3.4 of the Custodial Agreement), the Servicer will promptly
reimburse the Master Servicer for such payments.

            Section 9.2 Servicer Mortgage Loan Files

            9.2.1. Servicer Mortgage Loan File Requirements. The Servicer must
maintain a Servicer Mortgage Loan File for each Mortgage Loan, which may be
distributed among several different files, each of which shall be clearly marked
with the Servicer Loan Number and shall be readily accessible to the Master
Servicer during regular business hours, that includes the following:

            (a) copies of each of the documents listed in Section 2.01 of the
      Pooling and Servicing Agreement that are held by the Custodian as part of

      applicable;

            (b) where such coverage is not provided under a blanket policy
      maintained by the Servicer, an original Hazard Insurance policy, or a copy
      thereof, or a certificate of insurance issued by the applicable insurer or
      its agent indicating such a policy is in effect for the related Mortgaged
      Property;

            (c) a Flood Insurance policy or a certificate of insurance issued by
      the insurer or its agent indicating that such a policy is in effect with
      respect to the related Mortgaged Property, if Flood Insurance is required
      pursuant to the provisions of Section 15.4 or Section 16.6 hereof for such
      Mortgaged Property;

            (d) originals or copies of all documents submitted to a Primary
      Mortgage Insurer for credit and property underwriting approval with
      respect to the related Mortgaged Property, if Primary Mortgage Insurance
      is required pursuant to the provisions of Section 15.2 hereof for such
      Mortgaged Property;

pursuant to Section 10.3.1 hereof.

            10.1.2. Mortgage Loans without Escrow. If the Servicer is not
required to collect Escrow Funds on a Mortgage Loan, the Servicer shall require

collecting Escrow Funds with respect to a Mortgage Loan, or (b) the Borrower has
not been obliged to make Escrow Funds payments or such payments have been waived
and such Borrower has failed to timely pay obligations which otherwise would be
Escrow Items, the Servicer must pay any obligation (i) which could become a
first lien on the related Mortgaged Property, or (ii) to maintain in force the
applicable Insurance Policies. Where Escrow Funds are maintained by the
Servicer, such obligations should be paid from the Borrower's Escrow Funds, or
in accordance with Section 10.2.3 hereof.

such Borrower. If sufficient additional funds have not been recovered by the
time the payment is due, the Servicer must advance its own funds to ensure
prompt payment. The Servicer may elect to advance funds prior to attempting to
obtain the additional funds from such Borrower; however, to the extent permitted
by applicable law, the Servicer shall thereafter attempt to obtain the advanced
funds from the Borrower or collect such advanced funds as described in Section
10.3.3.

Escrow Funds at least annually to determine the monthly deposits which must be
made by such Borrower. The analysis shall be performed based upon (a) reasonable
projections of the expenses to be paid from the Escrow Funds and (b) that as
such expenses come due, the Escrow Funds balance shall at all times be
sufficient to effect the payment of such expenses, unless a lower amount is
required by applicable law. Each Borrower must receive a statement of this
analysis. The analysis also must determine whether there is a surplus or
deficiency in such Borrower's Escrow Funds.

            10.3.2. Escrow Fund Surplus. A surplus in a Borrower's Escrow Funds
shall be refunded to such Borrower or taken into consideration in determining
the amount to be collected for Escrow Funds.

            10.3.3. Escrow Fund Deficiency. Where it is determined that a
deficiency exists in such Borrower's Escrow Funds, such Borrower may be
requested to pay the shortage in full or the deficiency may be taken into
consideration in determining the amount to be collected for Escrow Funds during
the next twelve months (or such longer period as may be permitted in the
discretion of the Servicer).

or GPARM Loan which provides for negative amortization in the future) that has
amortized down so that its current LTV is 80% or less, the Servicer may waive
the Borrower's future obligation to make Escrow Funds payments provided:

            (a) the Unpaid Principal Balance of such Mortgage Note divided by
      the value of the Mortgaged Property based on an appraisal made within 60
      days of the date of determination is 80% or less;

            (b) such Mortgage Loan is at least 12 months old; and

            (c) such Mortgage Loan has not been more than 30 days delinquent
      during the preceding 12 months.

            10.5.2. Waiver Rescission. The Servicer shall enforce the Escrow
Funds requirements with respect to any Mortgage Loan if the related Borrower
fails to act responsibly in making the required payments.

                  individual who established the trust) under a divorce decree
                  or legal separation agreement or from an incidental property
                  settlement agreement, provided that the transferee will occupy
                  the Mortgaged Property;

            (vi)  a transfer of a Mortgaged Property that is jointly owned by
                  unrelated co-borrowers from one of the Borrowers to the other,

                  (or, if the Borrower is an inter vivos revocable trust, into a
                  new trust), so long as the Borrower (or the individual who
                  established the original inter vivos revocable trust) will be
                  the beneficiary of the trust and the occupant of the Mortgaged
                  Property;

            (viii) the granting of a leasehold interest in the Mortgaged
                  Property that has a term of three or fewer years and does not
                  provide an option to purchase the Mortgaged Property, or a
                  renewal option that would allow the term to extend beyond
                  three years;

            (ix)  the creation of a subordinate lien upon the Mortgaged
                  Property, provided that there is no transfer of occupancy
                  rights therein; or

            (x)   the creation of a purchase money security interest for
                  household appliances which are situated in or upon the
                  Mortgaged Property.

            (b) If the individual or entity transferring the Mortgaged Property
      requests a release of liability, the Servicer must review the credit and
      financial capacity of the individual or entity receiving the Mortgaged
      Property. The Servicer may approve the release of liability if it believes
      the recipient is capable of assuming the mortgage obligations and, where
      applicable, with the consent of the respective Primary Mortgage Insurer
      and/or the respective Pool Insurer. If the Servicer does not believe that
      the recipient is credit worthy or if the consent of the respective Primary
      Mortgage Insurer and/or the respective Pool Insurer is required but not
      obtained, the Servicer shall deny the request for the release of
      liability, although the transfer may still be processed without the
      release. If the request is denied based solely on the Primary Mortgage
      Insurer's or the respective Pool Insurer's decision, the denial letter
      should state that fact.

            (c) The Servicer shall advise (i) each insurance company providing
      Hazard Insurance and Flood Insurance, where applicable, (ii) the relevant
      tax authorities, where applicable, (iii) the respective Primary Mortgage
      Insurer and/or the respective Pool Insurer and (iv) other interested
      parties when it processes transactions under this Section 11.3.4. The
      Master Servicer does not need to be notified about such a transaction
      unless the Servicer agrees to a release of liability under Section
      11.3.4(b).

            Section 11.4 Assumptions

      Instrument continues to evidence a valid and perfected first lien on the

            (d) ensure that any and all cash consideration received is applied
      to the Unpaid Principal Balance of such Mortgage Loan to the extent of the
      diminution of the value of such Mortgaged Property;

            (e) cause all legal documents for the transaction to be reviewed;

            (f) ensure that such Mortgaged Property, following such release or
      change, adequately secures the Unpaid Principal Balance of the Mortgage
      Loan and accrued interest thereon and that the related Loan-to-Value ratio
      will not be greater than 80%, after giving effect to clause (d) hereof;
      and

            (g) obtain written notification from the respective Title Insurer
      that the related Title Insurance policy remains fully in effect with
      respect to such Mortgaged Property, as modified, following such release or
      change.

            11.5.2. Release or Modification of Lien. With the consent, where
applicable, of the respective Primary Mortgage Insurer, and/or the respective
Pool Insurer, the Servicer may approve applications for partial release of a
Mortgaged Property from the lien of the related Security Instrument, easements,
consent to substantial alterations and any other changes affecting the related
Mortgage Loan or such Mortgaged Property if the perquisites in Section 11.5.1
have been satisfied.

            11.5.3. Master Servicer's Approval. If the Servicer is not able to
meet the prerequisites specified in Section 11.5.1 or if the amount of
consideration received is less than the reduction in the value of the Mortgaged
Property due to the partial release or other changes, the Servicer must obtain
the approval of the Master Servicer prior to permitting an application described
in Section 11.5.2. The Servicer shall furnish such information as the Master
Servicer shall request in connection with an application under this Section
11.5.3.

            Section 11.6 Recordation of Assignments

            11.6.1. Recordation Requirement. The Servicer must, at its own
expense, record the Assignment of each Security Instrument (other than with
respect to any Mortgage Loan registered in the name of MERS) to the Trustee or,
if applicable, to the Trust Administrator on behalf of the Trustee, as well as
any previously unrecorded intervening Assignments. In the case of any Mortgage
Loan registered in the name of MERS, the Servicer shall take all actions as are
necessary to cause the Trustee or, if applicable, to the Trust Administrator on
behalf of the Trustee, to be shown as the owner of the related Mortgage Loan on
the records of MERS for purposes of the system of recording transfers of
beneficial ownership of mortgages maintained by MERS. If any Security Instrument
or Assignment is not recorded within the later to occur of (i) the date 120 days
after the acquisition of the a Mortgage Loan by the Trustee or, if applicable,
the Trust Administrator on behalf of the Trustee, if the Servicer has been
servicing such Mortgage Loan from the Trustee's or, if applicable, the Trust
Administrator's date of acquisition or (ii) the date 120 days after the date the
Servicer began servicing such Mortgage Loan, the Master Servicer shall have the
right to so effect such recordation at the Servicer's expense.

            11.6.2. Extension of Recording Period. The time to record an
Assignment of a Security Instrument may be extended from the end of permissible
recordation period set forth in Section 11.6.1 if the Servicer provides an
Officer's Certificate acceptable to the Master Servicer certifying that the
Servicer has used its best efforts to complete the recordation process for the
Security Instrument and/or Assignment, as applicable, and that the factors
preventing completion of the recordation process are beyond the Servicer's
control.

            11.6.3. Delivery Requirement. Promptly following the recordation of
any Security Instrument or an Assignment, the Servicer shall deliver to the
Custodian, unless otherwise directed in writing by the Master Servicer, such
Security Instrument or Assignment bearing evidence of recordation or, if the
original Security Instrument or Assignment is retained by the recording office,
a certified copy of the original recorded Security Instrument or Assignment.

            11.6.4. Waiver of Recordation. The Master Servicer shall generally
require the Servicer to record an Assignment of the Security Instrument for each
Mortgage Loan to the Trustee or, if applicable, to the Trust Administrator on
behalf of the Trustee. However, the recordation requirement with respect to an
Assignment may be waived for a Mortgage Loan if (a) the related Mortgaged
Property is in a state in which recordation of such an Assignment is not
required to protect the Trustee's right, title and interest in and to the
related Mortgage Loan and the Depositor or the Servicer has delivered to the
Master Servicer an Opinion of Counsel, acceptable to the Master Servicer, to
that effect or (b) the Master Servicer has been advised by the Depositor that
the nonrecordation of an Assignment in a state will not result in a reduction of
the rating assigned by each Rating Agency at the time of the initial issuance of
the Wells Fargo Asset Securities Corporation, Mortgage Pass-Through
Certificates, Series 2007-4.

            Section 11.7 General Servicing Considerations

            11.7.1. Abandonment. If the Servicer discovers that any Mortgaged
Property is not occupied, the Servicer must immediately attempt to contact the
Borrower in order to determine the reason for the vacancy. If the Servicer
determines that such Mortgaged Property has been abandoned, the Servicer, at its
own expense, must take all necessary actions to protect such Mortgaged Property
from waste, damage and vandalism. Such expenses shall be recoverable by the
Servicer solely from the Liquidation Proceeds of the related Mortgage Loan, if
any, or directly from the Borrower.

            11.7.2. Buydown Funds. The Servicer must distribute any Buydown
Funds in each Custodial Buydown Account in accordance with the terms of the
applicable Buydown Agreement.

            11.7.3. Maintenance of Records. Based upon information obtained
pursuant to its obligations under Section 12.2.6, the Servicer shall maintain
accurate records of the occurrence of any of the following:

            (a) deterioration of, waste of, or lack of repair to, any Mortgaged
      Property, which materially and adversely affects the Value of such
      Mortgaged Property and the Borrower refuses or is not financially able to
      make the necessary repairs;

            (b) sale or transfer of any Mortgaged Property in a manner not
      approved by the Servicer pursuant to the provisions of this Agreement;

            (c) material litigation involving any Mortgaged Property;

            (d) abandonment of any Mortgaged Property;

            (e) a material default, determined in accordance with Prudent
      Servicing Practices, under the terms of any Security Instrument, Mortgage
      Note, Condominium Project or PUD constituent document or similar
      obligations of a Borrower; or

            (f) any other situation that may materially and adversely affect the
      value of any Mortgage Loan.

            11.7.4. Eminent Domain. The Servicer must submit appropriate
recommendations and documentation to, where applicable, the respective Primary
Mortgage Insurer and/or the respective Pool Insurer, of any taking by eminent
domain if:

            (a) the Mortgaged Property will be taken in whole and the
      consideration to be paid to the Borrower will be insufficient to satisfy
      the Unpaid Principal Balance (plus any unreimbursed Advances) of the
      related Mortgage Loan, or

            (b) the Mortgaged Property will be taken in part and (i) the ratio
      of the (A) Unpaid Principal Balance (plus any unreimbursed Advances) of
      the Mortgage Loan to (B) the Current Value of the remaining Mortgaged
      Property is higher than (ii) the LTV ratio of the Mortgage Loan
      immediately before the taking, even after applying any consideration to
      the Unpaid Principal Balance of the Mortgage Loan.

      The Servicer must take all steps necessary to prevent loss of any
      Primary Mortgage Insurance or Pool Insurance benefits due to any
      taking by eminent domain.

            11.7.5. Late Charges. Late charges may not be assessed unless a
Borrower failed to make payments in accordance with the Mortgage Note.

            Section 11.8 Borrower Bankruptcy

            11.8.1. Servicer's Duty. The Servicer shall be responsible for
representing the interests of the Trustee in any bankruptcy proceedings
involving a Borrower.

            11.8.2. Responsibility for Costs. The costs of protecting the
interests of the Trustee shall be advanced by the Servicer and are not (a)
chargeable to the related Borrower's Escrow Funds or (b) reimbursable from the
Master Servicer.

            11.8.3. Challenge Bankruptcy Reductions. If the bankruptcy judge or
trustee should propose to (a) reduce the Unpaid Principal Balance of a Mortgage
Note, (b) reduce the related Mortgage Interest Rate, (c) extend the final
maturity of such Mortgage Note, or (d) reduce the level of any monthly payment
on such Mortgage Note, the Servicer shall (i) challenge any such modification on
a timely basis and (ii) exercise reasonable judgment to protect the interests of
the Trustee.

            11.8.4. Bankruptcy Adjustments. If the action of any court results
in a Deficient Valuation or Debt Service Reduction, the Servicer shall provide a
calculation of the effects of such modification notifying the Master Servicer of
the new principal balance, Mortgage Interest Rate, new final maturity, or
monthly payment level, as the case may be, of such Mortgage Loan.

            11.8.5. Bankruptcy Plan Surveillance. With respect to each Mortgage
Loan which is the subject of a Deficient Valuation or a Debt Service Reduction,
the Servicer shall verify that payments are being made in accordance with the
plan approved in the related bankruptcy proceedings.

                                   ARTICLE 12

                             Delinquency Management

            Section 12.1 In General

            12.1.1. Servicing Practices. The provisions set forth in this
Article constitute the minimum guidelines and procedures for servicing
Delinquent Mortgage Loans. The Servicer must use collection procedures which
meet or exceed these guidelines. The Servicer's procedures must be sufficient
for promptly dealing with delinquencies. The Master Servicer retains the right
to require the Servicer to perform additional collection procedures which the
Master Servicer deems, in its reasonable discretion, necessary to realize the
objectives set forth herein or otherwise to protect the interests of the
Trustee.

            12.1.2. Servicer's Capabilities. The Servicer's collection staff
must be sufficiently skilled in financial counseling and mortgage servicing
techniques to assist a Borrower to bring his Mortgage Loan current and to
protect his equity and credit rating, while at the same time protecting the
interests of the Trustee and of the Master Servicer.

            12.1.3. Servicing Objectives. The purpose of any collection effort
is to cure a Delinquency in the shortest possible time. The Servicer should
treat each Delinquency individually. Discussions with the Borrower must cover
the cause of such Delinquency and the time frame in which such Delinquency shall
be cured. The Servicer should use notices, letters, telegrams, telephone calls,
face-to-face contact and other responsible collection techniques consistent with
Prudent Servicing Practices. The Servicer is required to maintain all collection
records. The Servicer must vary its collection techniques to fit individual
circumstances, avoiding a fixed collection pattern which may be ineffective in
dealing with particular Borrowers. The Servicer should recognize the importance
of telephone and face-to-face contact in any collection program. As part of its
collection procedures, the Servicer shall closely monitor all newly originated
Mortgage Loans.

            12.1.4. Servicer's Expenses. Unless otherwise specified, the cost of
any of the servicing procedures detailed in this Agreement shall be borne solely
by the Servicer. The Servicer may not charge such expenses against the
Borrower's Escrow Funds. The foregoing shall not preclude the Servicer from
recovering such expenses from the Borrower to the extent permitted by applicable
law and the related Mortgage Loan Documents.

            Section 12.2 Delinquency Servicing Procedures

            12.2.1. Late Notice. A late notice shall be mailed by the Servicer
to the Borrower by the 18th day of such Delinquency.

            12.2.2. Telephonic Inquiry. The Servicer shall use best efforts to
make telephone contact with the Borrower by the 22nd day of such Delinquency.

            12.2.3. Notice of Default. Notification of default of such Mortgage
Loan shall be mailed by the Servicer to the Borrower by the 35th day of such
Delinquency.

            12.2.4. Borrower Interview. The Servicer shall comply with
applicable FNMA and FHLMC requirements with regard to Borrower interviews.

            12.2.5. Continuing Contacts. If satisfactory arrangements have not
been made to cure such Delinquency by the 90th day, the Servicer must continue
to contact the Borrower until either the related Mortgage Loan has been brought
current or the Servicer has made the decision to commence foreclosure of such
Mortgaged Property or other action.

            12.2.6. Property Inspection. The Servicer is required to inspect
each Delinquent Mortgaged Property at such time and in such manner as is in
accordance with Prudent Servicing Practices. The Servicer must prepare a
Property Inspection Report following each inspection. All Property Inspection
Reports must be retained by the Servicer and copies thereof must be forwarded to
the Master Servicer promptly upon request. All expenses related to the foregoing
shall be recoverable by the Servicer from the Principal or from Liquidation
Proceeds, Insurance Proceeds, payments on the related Mortgage Loan or any other
source relating to the related Mortgage Loan or the related Mortgaged Property.
The foregoing shall not preclude the Servicer from recovering such expenses from
the Borrower to the extent permitted by applicable law and the related Mortgage
Loan Documents.

            Section 12.3 Relief of Borrowers

            12.3.1. Servicer's Role. The Servicer shall be readily available to
Borrowers to offer skilled financial counsel and advice and shall make personal
contact with delinquent Borrowers as often as possible to achieve a solution
that will bring the Mortgage Loan current as soon as possible. The Servicer
shall be fully familiar with the form of relief to Borrowers provided for herein
and shall employ such relief.

            12.3.2. Servicer's Discretion. The Servicer shall have reasonable
discretion to extend appropriate relief to Borrowers who encounter hardship and
who are cooperative and demonstrate proper regard for their obligations.
However, no such relief shall be granted to any Borrower under a Mortgage Loan
unless the Servicer reasonably believes that there is a reasonable expectation
that such Borrower shall bring his Mortgage Loan current within a period
conforming to acceptable servicing practices; provided that such period will not
exceed 21 months from the Due Date of the earliest unpaid installment and will
not result in a "significant modification" of the Mortgage Loan under the REMIC
Provisions.

            12.3.3. Relief Requirement. Prior to granting relief with respect to
a delinquent Mortgage Loan as herein provided, the Servicer shall ascertain that
(i) the reasons for the default and (ii) the attitude and circumstances of such
Borrower justify the relief to be granted.

            12.3.4. Primary Mortgage Insurance Considerations. Where applicable,
the Servicer shall satisfy all requirements under the applicable Primary
Mortgage Insurance policy regarding the relief granted with respect to a
delinquent Mortgage Loan.

            12.3.5. Responsibility for Costs. The Servicer is responsible for
collection from such Borrower of any recording or similar costs or expenses
incidental to the granting of relief with respect to a delinquent Mortgage Loan.

            12.3.6. Forbearance Plan. (a) Where relief is appropriate, the
Servicer shall arrange with a Borrower a "Forbearance Plan" giving such Borrower
a definite period in which to reinstate his Mortgage Loan by immediately
commencing payments in excess of the regular Monthly Payments. Without the prior
written consent of the Master Servicer, special forbearance relief agreements
reducing or suspending the regular Monthly Payment of the related Mortgage Loan
for a specified period of time are not permitted. To the extent that (i) the
priority of the lien represented by such Mortgage Loan remains in effect and is
not adversely affected, (ii) where applicable, the related Primary Mortgage
Insurance policy remains in full force and effect and (iii) where applicable,
the related Pool Insurance policy remains in full force and effect, the
Servicer, in its discretion, may enter into a Forbearance Plan that provides
that the total amount owed during such Delinquency, including costs and
expenses, will be repaid within the shortest period practicable, commencing
immediately. With respect to such Mortgage Loan, the Forbearance Plan shall
provide that such Delinquency will be cured within a period conforming to
acceptable servicing practices; provided that such period will not exceed 21
months from the Due Date of the earliest unpaid installment and will not result
in a "significant modification" of the Mortgage Loan under the REMIC Provisions.
The Forbearance Plan for such Mortgage Loan shall be set forth in writing and
executed by the Borrower and by the Servicer in the form of a letter agreement
if the earliest unpaid installment is more than 60 days past due.

            (b) The Servicer may modify the payment terms of Mortgage Loans that
      are in default, or as to which default is reasonably foreseeable; provided
      that no such modification shall reduce the Unpaid Principal Balance of
      such Mortgage Loan or permanently reduce the Mortgage Interest Rate of
      such Mortgage Loan; and provided further that prior to entering into any
      such modification the Servicer and the Master Servicer shall determine
      that such modification is likely to increase the proceeds of such Mortgage
      Loan over the amount expected to be collected pursuant to a foreclosure or
      other similar procedure. Nothing in this Section 12.3.6(b) shall be
      construed to limit the ability of the Servicer to arrange for the sale of
      a Mortgaged Property pursuant to Section 13.3.3.

            12.3.7. Accommodation Limitations. No modification, recast,
extension, or capitalization of delinquent payments of a Mortgage Loan other
than as provided in Section 12.3.6 hereof shall be permitted with respect to a
Mortgage Loan.

            12.3.8. Pool Insurance Considerations. Where applicable, the
Servicer shall satisfy all requirements under the applicable Pool Insurance
policy regarding the relief granted with respect to a delinquent Mortgage Loan,
including, without limitation, securing the prior written consent of the
respective Pool Insurer regarding (a) any change in any term of such Mortgage
Loan, (b) the release of the related Borrower from any liability related to such
Mortgage Loan, or (c) the release of any portion of, or interest in, the
Mortgaged Property from the lien of the related Security Instrument.

            Section 12.4 Special Delinquency Servicing Considerations

            12.4.1. Advance Responsibility During Delinquency. In the event of a
Delinquency with respect to a Mortgage Loan, the Servicer agrees to advance from
its own funds the full amount of Monthly Payments (which may be net of the
related Servicing Fee) for such Mortgage Loan. These advances shall provide the
Trustee with a regular flow of funds on such delinquent Mortgage Loan. The
advance obligation stated above is in addition to any other advance obligations
which the Servicer has pursuant to the provisions of this Agreement. The
Servicer must still advance funds in accordance with the provisions of this
Agreement even if a forbearance has been granted.

            12.4.2. Primary Mortgage Insurance Compliance. Where applicable, the
Servicer shall be familiar with and shall satisfy all requirements of the
applicable Primary Mortgage Insurance policy with respect to a delinquent
Borrower. The Servicer shall have adequate controls to assure timely filing of
all notices to the appropriate Primary Mortgage Insurer. The Servicer shall
prepare and file all appropriate claims with respect to the applicable Primary
Mortgage Insurance policy and the Servicer shall prepare and, upon request,
deliver to the Master Servicer, copies of all claims forms and other papers
received from or presented to any Primary Mortgage Insurer in connection with
any claims presented under any such policy.

            12.4.3. Pool Insurance Compliance. Where applicable, the Servicer
shall be familiar with and shall satisfy all requirements of the applicable Pool
Insurance policy with respect to a delinquent Borrower. The Servicer shall have
adequate controls to assure timely filing of all notices to the appropriate Pool
Insurer. Copies of all such notices shall be sent to the Master Servicer upon
request. The Servicer shall prepare and file all appropriate claims with respect
to the applicable Pool Insurance policy and the Servicer shall prepare and, upon
request, deliver to the Master Servicer, copies of all claims forms and other
papers received from or presented to any Pool Insurer in connection with any
claims presented under any such policy.

                                   ARTICLE 13

                           Foreclosure Administration

            Section 13.1 Foreclosure Prerequisites

            13.1.1. Foreclosure/Alternative to Foreclosure Initiation. (a) When
a Borrower reaches the 90th day of Delinquency and the Servicer has exhausted
all reasonable means of curing the Delinquency, the Servicer shall either begin
the foreclosure process or suggest an alternative to foreclosure in accordance
with Prudent Servicing Practices. In conjunction with the Servicer's decision to
begin the foreclosure action or seek an alternative to foreclosure, the Servicer
shall provide written notice to, where applicable, the respective Primary
Mortgage Insurer and/or the respective Pool Insurer no later than ten days after
the initiation of foreclosure proceedings or the alternative to foreclosure.
Notwithstanding anything to the contrary in this Section 13.1.1, the Master
Servicer may direct the Servicer to stop the foreclosure action or to modify any
alternative to foreclosure. The Servicer shall prepare all necessary
documentation to initiate the foreclosure proceedings.

            (b) Notwithstanding anything to the contrary in this Section 13.1,
      if the Master Servicer has entered into a special servicing agreement
      pursuant to Section 3.08 of the Pooling and Servicing Agreement, the
      Master Servicer may direct the Servicer to commence foreclosure
      proceedings as contemplated by such special servicing agreement.

            13.1.2. Foreclosure Expenses. All fees and expenses shall be
consistent with FNMA standards and, where applicable, shall not exceed those
permitted under the respective Pool Insurance policy and/or the respective
Primary Mortgage Insurance policy. Fees in excess of the amount permitted by
FNMA guidelines or extraordinary legal services must be approved in writing in
advance, where applicable, by the respective Primary Mortgage Insurer or the
respective Pool Insurer, as the case may be, if required by the applicable
policy. All attorneys' fees, and other costs in excess of FNMA's standards in
respect of any foreclosure or acquisition in lieu of foreclosure shall be
identified in advance and a detailed estimate of the amounts thereof shall be
set forth in the Servicer's written recommendation. The billing by a foreclosure
attorney must demonstrate the appropriateness of any extraordinary fees by the
services required. In cases of full or partial reinstatement of the related
Mortgage Loan, the fees shall be reasonable and in proportion to the authorized
fee for services rendered for a completed foreclosure. Unless otherwise
expressly agreed in writing, neither the Master Servicer, any of its Affiliates,
their respective officers, directors, employees, agents, successors or assigns,
the Trustee nor, if applicable, the Trust Administrator shall be liable for any
attorneys' fees, trustees' fees, witness fees, title search fees, court costs or
other expenses incurred by the Servicer in respect of any foreclosure or
acquisition in lieu of foreclosure, except to the extent that such fees, costs
and expenses are fully reimbursable under a Primary Mortgage Insurance policy
and in fact are reimbursed.

            13.1.3. Hazardous Wastes. In the event that the Mortgaged Property,
related to a Mortgage Loan which is being considered for liquidation by
foreclosure or the transfer of a deed-in-lieu of foreclosure, contains, and the
Servicer has reason to believe that it contains, hazardous or regulated
substances which may impose liability, for damages, remediation or otherwise,
upon the owner of such Mortgaged Property pursuant to Federal, State or local
law, the Servicer shall not, except with the express prior written approval of
the Master Servicer, which approval makes specific reference to the presence of
such hazardous or regulated substances, undertake or continue the process of
foreclosure with respect to such Mortgaged Property.

            Section 13.2 Deed-in-Lieu of Foreclosure

            13.2.1. Conditions. If the Master Servicer and the respective
Primary Mortgage Insurer and/or the respective Pool Insurer, if applicable, have
approved the liquidation of a Mortgage Loan by accepting a deed-in-lieu of
foreclosure of the related Mortgaged Property, the Servicer may accept such deed
without any further action or approval by the Master Servicer or, where
applicable, the respective Primary Mortgage Insurer and/or the respective Pool
Insurer, provided that:

            (a) the Servicer determines that the pursuit of a deficiency
      judgment is not practical or warranted;

            (b) the Mortgaged Property has been listed for sale at a market
      value for three months or more without a reasonable sales offer;

            (c) there reasonably appear to be legal impediments to pursuing
      foreclosure;

            (d) the acceptance of the deed-in-lieu of foreclosure will enable
      the Trustee to acquire the Mortgaged Property earlier than under a
      foreclosure action;

            (e) the Borrower acknowledges in writing that the deed is being
      accepted as an accommodation to him or her;

            (f) where applicable, the respective Primary Mortgage Insurer and/or
      the respective Pool Insurer has agreed to the acceptance of a
      deed-in-lieu;

            (g) the Borrower has not received cash consideration to deed the
      Mortgaged Property over to the Trustee, unless the Master Servicer
      otherwise approves;

            (h) the Borrower can convey acceptable marketable title, evidenced
      by a Title Insurance policy;

            (i) the Mortgaged Property is vacant (unless, where applicable, the
      respective Primary Mortgage Insurer and/or the respective Pool Insurer has
      agreed to accept an occupied property);

            (j) the Mortgaged Property is not subject to liens (held by others),
      judgments, or attachments; and

            (k) the Borrower agrees to assign and transfer to the benefit of the
      Trustee, where applicable, any rents if the Mortgaged Property is rented,
      and the Servicer agrees to collect any rental income.

            13.2.2. Subsequent Actions. Upon acquisition by the Trustee, the
Servicer shall promptly notify, if applicable, the respective Primary Mortgage
Insurer and/or the respective Pool Insurer, indicating the details of the
transaction and reasons for the conveyance and providing such other information
as is required under a Primary Inspection Report to, if applicable, the Primary
Mortgage Insurer and/or the Pool Insurer. Title shall be conveyed directly from
the Borrower to the Trustee or to such other Person designated by the Master
Servicer.

            Section 13.3 Actions Prior to Foreclosure

            13.3.1. Notice Requirements. The Servicer shall send the Borrower a
letter, not less than 30 days before the commencement of foreclosure
proceedings, setting out (i) the nature of the default, (ii) the steps that must
be taken by the Borrower to cure the default and (iii) the date when foreclosure
proceedings will begin. If the Servicer has reason to believe that the related
Mortgaged Property has been abandoned or if the Borrower has displayed an
obvious disregard for his obligations under such Mortgage Loan, the foregoing
notice shall be forwarded at the earliest possible date following the Borrower's
default.

            13.3.2. Initiation of Proceedings. If foreclosure approval has not
been withheld by the Master Servicer and, where applicable, by the respective
Primary Mortgage Insurer and/or the respective Pool Insurer, with respect to a
Mortgaged Property, including Co-op Shares, the Servicer shall, unless it
arranges for the sale by the Borrower of the Mortgaged Property to a third party
pursuant to Section 13.3.3, initiate or cause to be initiated such foreclosure
actions as are authorized by law and consistent with practices in the locality
where the Mortgaged Property is located, including, in the case where such
Mortgaged Property includes a residential long-term lease, the succession by the
Servicer to the rights of the Borrower under the lease by foreclosure,
assignment in lieu of foreclosure or other comparable means. If such Mortgaged
Property has been abandoned or vacated by the Borrower and the Borrower has
evidenced no intention of honoring his obligations under the related Mortgage
Loan, the foreclosure process shall be expedited to the fullest extent permitted
by law.

            13.3.3. Short Sale of Defaulted Mortgage Loans in Lieu of
Foreclosure. With respect to any defaulted Mortgage Loan for which the Servicer
would otherwise be required to initiate foreclosure proceedings, the Servicer
may arrange for the sale of the Mortgaged Property by the Borrower to a third
party if, in the good faith judgment of the Servicer, the net proceeds from such
sale would be equal to or greater than the net proceeds of a bid conducted in
accordance with Section 13.4.2.

            Section 13.4 Foreclosure Procedures

            13.4.1. Foreclosure Expenses. During the period in which the
Mortgaged Property related to a Mortgage Loan is being foreclosed, remaining
Escrow Funds, if any, as well as any rent receipts, shall be used to pay all
taxes and insurance premiums that become due with respect to such Mortgaged
Property to the extent permitted by law. Except where other arrangements have
been made with the applicable Primary Mortgage Insurer, the Servicer shall, with
respect to each Mortgaged Property undergoing foreclosure, advance payment of
attorneys' fees, trustees' fees and other foreclosure costs from the
commencement of foreclosure proceedings pertaining to such Mortgaged Property.

            13.4.2. Bidding Instructions. . The Servicer shall issue bidding
instructions to the attorney or trustee in a foreclosure proceeding in
accordance with Prudent Servicing Practices. Where applicable, the Servicer
shall incorporate any bidding requirements issued by the respective Primary
Mortgage Insurer and/or the respective Pool Insurer. Any proceeds received from
an insurance loss settlement shall be included as part of the bid amount. Where
a claim or claim settlement under a Hazard Insurance or Flood Insurance policy
is pending, the Servicer shall contact the Hazard Insurance or Flood Insurance
carrier to verify that the proposed bid will not invalidate the claim, in that,
in certain jurisdictions, a bid for the total indebtedness will be considered as
satisfaction of the debt and would thus bar the Hazard Insurance or Flood
Insurance claim.

            13.4.3. Buydown Funds Use. Unless the related Buydown Agreement
provides otherwise, the Servicer may not use Buydown Funds relating to a
Mortgage Loan to cure a Delinquency with respect to such Mortgage Loan. Any
Buydown Funds remaining in the associated Custodial Buydown Account of a
Mortgage Loan in foreclosure must be disposed of in accordance with the terms of
the related Buydown Agreement.

            13.4.4. Servicer's Responsibilities. Subject to the provisions of
Article Three hereof, after acquisition of a Mortgaged Property, through
foreclosure or a deed-in-lieu of foreclosure, or after the Servicer shall have
taken possession of the Mortgaged Property, whichever occurs first, the Servicer
shall be responsible for the management of such Mortgaged Property. The Servicer
shall remain responsible until possession has been assumed by the applicable
Primary Mortgage Insurer or the applicable Pool Insurer or until such Mortgaged
Property are otherwise disposed of, as the case may be. The Servicer shall take
such action as is necessary to protect the Trustee's security or, after
acquisition thereof, ownership interest in such Mortgaged Property. Such action
shall include, without limitation, (i) management of such Mortgaged Property,
(ii) maintenance of such Mortgaged Property and (iii) if such Mortgaged Property
are vacant, protection of such Mortgaged Property against vandals and the
elements.

            13.4.5. Conveyance Documents. Where applicable, any conveyance by
the Servicer to the respective Primary Mortgage Insurer or the respective Pool
Insurer of a Mortgaged Property shall be made by the form of deed commonly used
in the particular jurisdiction where such Mortgaged Property is located. The
Servicer shall prepare the necessary documents within two weeks after the date
of sale at foreclosure or confirmation of sale, if applicable, or within a
reasonable time frame. The documents shall be forwarded to the Trustee for
approval and execution. After execution by the Trustee, such documents will be
returned to the Servicer for delivery to the respective Primary Mortgage Insurer
or the respective Pool Insurer which is acquiring such Mortgaged Property.

            Section 13.5 Mortgage Loan Reinstatement

            13.5.1. Borrower's Full Payment. If a Borrower offers to fully
reinstate his Mortgage Loan during the foreclosure process, the Servicer shall
accept the offer. To achieve full reinstatement of his Mortgage Loan, a Borrower
shall make payment of all (i) payments due to bring such Mortgage Loan current,
(ii) attorneys' fees, (iii) trustees' fees, (iv) any additional legal costs, (v)
all applicable late fees and (vi) any other expenditures or Advances made by the
Servicer during the foreclosure process.

            13.5.2. Borrower's Partial Payment. Except where otherwise required
by applicable law, the Servicer may not accept an amount in payment from a
Borrower which is less than the amount required for full reinstatement pursuant
to Section 13.5.1 hereof toward reinstatement of a Mortgage Loan during the
foreclosure process without the prior written approval from, if applicable, the
respective Primary Mortgage Insurer and/or the respective Pool Insurer.

            13.5.3. Obligations upon Reinstatement. Upon accepting the
reinstatement of a Mortgage Loan, the Servicer shall immediately contact the
appropriate foreclosure attorney or trustee to avoid incurring additional legal
costs or fees. The Servicer must apply the reinstatement Funds upon receipt from
a Borrower in payment of the expenses enumerated in Section 13.5.1 hereof. Upon
receipt of the reinstatement funds from a Borrower the Servicer must return to
the Custodian the related Mortgage Note and other related Mortgage Loan
Documents for reinclusion in the related Mortgage Loan File.

            13.5.4. Certain Assumptions Permitted. The Servicer is authorized,
notwithstanding the other provisions of this Article 13, to permit the
assumption of a defaulted Mortgage Loan rather than to foreclose or accept a
deed-in-lieu of foreclosure if, in the Servicer's judgment, the default is
unlikely to be cured and the assuming borrower meets the underwriting guidelines
that originally applied to such Mortgage Loan.

compensate the Master Servicer for any damages caused as a result of the

inefficiency in managing a REO may not be quantified in advance of the Master
Servicer assuming responsibility for such REO.

                         Insurance and Letter of Credit

            Section 15.1 General Provisions

            15.1.1. Insurance Requirements.

            The Servicer must verify that each Mortgage Loan has the insurance
coverage required pursuant to Article 15 and 16. All claims arising under

without limitation, the payment of premiums on a timely basis, by the Servicer
at no expense to the Trustee, the Trust Administrator (if applicable) or the
Master Servicer.

            If the Insurance Proceeds paid in respect of any Mortgage Loan are
not used to repair the related Mortgaged Property due to the particular
circumstances of the loss, and instead such Insurance Proceeds are applied to
reduce the Unpaid Principal Balance of such Mortgage Loan and such application
causes the Unpaid Principal Balance of such Mortgage Loan to reduce to zero, the
Servicer must treat the application of such proceeds as a Liquidation, and
notify the Master Servicer of such Liquidation.

            15.1.2. Uninsured Losses. The Servicer must take the following
actions in the event of loss or damage to any Mortgaged Property caused by an
earthquake, flood, tornado or other natural disaster immediately following, the

(y) the time at which the Servicer reasonably should have known of such loss or
damage in the exercise of Prudent Servicing Practices:

            (b) secure any abandoned Mortgaged Property from vandalism and the
      elements;

            (c) communicate with and counsel the respective Borrower on any
      disaster relief programs or other assistance which is available; and

            (d) take appropriate action to protect the interests of the Trustee
      and the respective Borrower.

            15.1.3. Servicer's Obligation to Maintain Insurance. If the Servicer
discovers that a Borrower does not have adequate insurance coverage as required
pursuant to the provisions of this Article, the Servicer must obtain and
maintain at its own expense the required insurance coverage on the related
Mortgaged Property. The Servicer may, in its discretion, cause the required
coverage to be maintained through a blanket insurance policy. Such expenses
shall not be recoverable by the Servicer from the Master Servicer or from
payments on the Mortgage Loan or any other source relating to the related
Mortgage Loan or the related Mortgaged Property, other than from Liquidation
Proceeds or Insurance Proceeds from the related Mortgage Loan. To the extent
permitted by applicable law and the related Mortgage Loan Documents, the
Servicer may initiate forced placed coverage with respect to such Mortgaged
Property and thereafter attempt to recover such expenses from the related
Borrower.

            15.1.4. Insurance Notices. The Servicer must arrange for all
insurance drafts, notices, policies, invoices, or other correspondence to be
delivered directly to the Servicer. The Servicer, its successors and assigns
must be named as the Mortgagee, the endorsement must show the Servicer's address

            West Des Moines, Iowa 50266

            15.1.5. Default by Insurer. If the Servicer knows or has reasonable
cause to suspect that an insurer under any applicable insurance policy required
pursuant to the provisions of this Article will, for any reason, be unable to
pay a valid claim, the Servicer shall immediately (i) find a substitute insurer
and (ii) pay any premiums to the insurer. In any case, the Servicer shall not be
liable in any way for the financial inability of any insurer under any insurance
policy required herein to pay a valid claim so long as the provisions of Article
15 and 16 hereof are complied with.

            15.1.6. Insurance Carrier Rating. Each Insurance Policy must be
underwritten by an insurance carrier that is a FNMA or FHLMC approved Mortgage
Insurer.

            15.1.7. Insurance Carrier Licenses. Each insurance carrier must be
licensed or otherwise authorized by law to conduct business in each state in
which a related Mortgaged Property is located.

            15.1.8. Risk Exposure. If any Mortgaged Property is exposed to
hazards not fully covered by Hazard Insurance or Flood Insurance, the Servicer
must notify the Master Servicer immediately with a recommendation for additional
coverage.

            15.1.9. Evidence of Insurance. (a) The Servicer must maintain the
following documentation with respect to insurance coverage on each Mortgage
Loan:

            (i)   if Primary Mortgage Insurance is required, a copy of the
                  Primary Mortgage Insurance policy and any related
                  endorsements;

            (ii)  for one- to four-unit dwellings where such coverage is not
                  provided under a blanket policy maintained by the Servicer, an
                  original of the Hazard Insurance policy, if applicable, and
                  any related endorsements;

            (iii) a copy of the Title Insurance policy and any related
                  endorsements, unless a Final Title Condition Report was
                  obtained;

            (iv)  For properties covered under a blanket policy, an original of
                  any blanket policy, and any related endorsements; and

            (v)   an original of any Flood Insurance policy, if Flood Insurance
                  is required, and any related endorsements.

            (b) A certificate of insurance is acceptable in lieu of any of the
      foregoing policies if it contains the following information:

            (i)   named insured and Mortgagee or, for PUD or Condominium Units,
                  named insured association, unit owner and unit owner
                  Mortgagee;

            (ii)  address of the Mortgaged Property;

            (iii) type, amount and effective dates of coverage;

            (iv)  deductible amount;

            (v)   any endorsement or optional coverage obtained and made part of
                  the original policy;

            (vi)  insurer's agreement to provide at least ten day's prior
                  written notice to the Servicer and Borrower (or applicable
                  unit owner Mortgagee if for a PUD or Condominium Unit) before
                  any reduction in coverage or cancellation of the policy; and

            (vii) signature of an authorized representative of the insurer, if
                  required by applicable law.

            Section 15.2 Primary Mortgage Insurance

            15.2.1. Primary Mortgage Insurance Requirement. Unless Primary
Mortgage Insurance coverage with respect to a Mortgage Loan is canceled as
provided in Section 15.2.4 herein, the Servicer must maintain at all times
Primary Mortgage Insurance on any Mortgage Loan with an original LTV ratio in
excess of 80%.

            15.2.2. Primary Mortgage Insurance Coverage. As to each Mortgage
Loan which is required to have Primary Mortgage Insurance, pursuant to this
Agreement or the related Mortgage Loan Documents, Primary Mortgage Insurance
must at least provide coverage which insures against loss of that portion of the
Unpaid Principal Balance of the Mortgage Loan that exceeds 75% of the Value of
the Mortgaged Property. If the Mortgage Loan provides for negative amortization
or for the potential of negative amortization, the Primary Mortgage Insurance
policy must also insure any increase in the Unpaid Principal Balance from the
original principal balance of the related Mortgage Note.

            15.2.3. Primary Mortgage Insurer Downgrading. In the event that the
rating assigned by a Rating Agency to the claims paying ability of any Primary
Mortgage Insurer is reduced below the level permitted under Section 15.1.6, the
Servicer shall use its best efforts to replace each Primary Mortgage Insurance
Policy issued by such Primary Mortgage Insurer with a new Primary Mortgage
Insurance policy issued by an insurer whose claims paying ability is acceptable
to the Master Servicer. The premium for any replacement Primary Mortgage
Insurance policy shall not exceed the premium for the discontinued Primary
Mortgage Insurance policy.

            15.2.4. Primary Mortgage Insurance Cancellation. If a Borrower
requests cancellation of the Primary Mortgage Insurance policy with respect to
his Mortgaged Property, the following requirements must be met:

            (a) The current LTV ratio must be 80% or less. The current LTV ratio
      must be calculated by dividing the Unpaid Principal Balance of the related
      Mortgage Loan by the Current Value of the Mortgaged Property;

            (b) The related Mortgage Loan may not have been 30 days or more
      delinquent within the preceding twelve months; and

            (c) There may not have been any other default under the terms of the
      related Mortgage Loan at any time during the preceding twelve months.

      If there are indications that the Current Value of the Mortgaged
      Property has declined, the Servicer shall obtain an Appraisal
      Report with respect to such Mortgaged Property that is not more
      than 60 days old. The Current Value of such Mortgaged Property
      set forth the Appraisal Report shall be used as the divisor in
      clause (a) hereof to determine whether the recalculated current
      LTV is 80% or less. If the recalculated current LTV is greater,
      the Primary Mortgage Insurance cancellation request will be
      denied.

            15.2.5. Primary Mortgage Insurance Claims. The Servicer must take
all steps to ensure the payment of the maximum benefits payable under the terms
of any Primary Mortgage Insurance policy. The Servicer must work diligently with
each Primary Mortgage Insurer to determine whether such insurer will settle the
claim by taking title to the Mortgaged Property in question or in some other
manner. Upon receipt of any Primary Mortgage Insurance proceeds, the Servicer
must deposit such amounts in the appropriate Custodial P&I Account. The Servicer
shall promptly notify the Master Servicer in writing if any Primary Mortgage
Insurer at any time denies any or all of a claim filed under its Primary
Mortgage Insurance policy.

            Section 15.3 Hazard Insurance

            15.3.1. Hazard Insurance Requirement. Unless alternative coverage is
provided pursuant to Section 16.3 hereunder, the Servicer must ensure that each
Mortgaged Property is covered at all times by Hazard Insurance.

            15.3.2. Hazard Insurance Coverage. As to each Mortgaged Property,
the amount of Hazard Insurance must be at least equal to the lesser of (a) the
Unpaid Principal Balance of the related Mortgage Loan or (b) 100% of the
insurable value of the improvements on the Mortgaged Property; provided,
however, that in no case shall the amount of Hazard Insurance be less than the

an Advance is a Non-Recoverable Advance, the Servicer shall employ a broker's
price opinion, which is no more than twelve months old when so employed, of the
fair market value of the Mortgaged Property related to the Mortgage Loan which
is subject to such Advance, and calculate the difference between (a) the fair
market value of such Mortgaged Property and (b) the sum of (i) a reasonable
estimate of foreclosure costs which may be incurred in the foreclosure of such
Mortgaged Property, and (ii) the amount of unreimbursed Advances made by the
Servicer with respect to the related Mortgage Loan pursuant to the terms of this
Agreement, is greater than zero. If such a difference is greater than zero, then
such difference represents the maximum amount of additional Advances which the
Servicer shall make before determining that any additional Advances in excess of
such amount are Non-Recoverable Advances. If such difference is negative, then
the magnitude of such difference is the amount of previously made unreimbursed
Advances which the Servicer may now regard as Non-Recoverable Advances. The
Servicer shall provide the Master Servicer with an Officer's Certificate upon
the determination that any Advance is a Non-Recoverable Advance.

maximum interest rate permitted by law.

recovered all Liquidation Proceeds with respect to a Mortgage Loan other than
any amounts as to which a Primary Mortgage Insurance claim has been made, the
Servicer shall have the option, but not the obligation, to advance the amount of
such claim (a "PMI Advance").

            PMI Advance Recovery. The Servicer's PMI Advance shall be
recoverable from the related Primary Mortgage Insurance proceeds; provided,
however that if such PMI Advance or a portion thereof is eventually determined
to be a Non-Recoverable Advance, the Servicer shall be entitled to reimbursement
pursuant to Section 17.4. Notwithstanding the foregoing, the Servicer shall not
be entitled to reimbursement for a PMI Advance if the amount is not recoverable
from the related Primary Mortgage Insurance proceeds as a result of an action by
the Servicer which violates Section 4.4.2.

by the Master Servicer, and, if applicable, any rating agency with respect

servicing portfolio.

            19.1.4. Master Servicer's Determination. If the transferor and

warranties and servicing requirements hereunder, the Master Servicer has the
right, in its reasonable discretion, to determine which party or parties are
liable for such violations.

of the servicing to such transferee. The Servicer shall not be entitled to
compensation for servicing following its termination.

            19.2.5. Effect of Termination. In the event of the termination of
this Agreement, the Servicer is not released from its obligations under this

Trustee and the Depositor for all reasonable expenses incurred by the Master
Servicer (or such designee), the Trustee or the Depositor, as such are incurred,
in connection with the termination of the Servicer as servicer and the transfer
of servicing of the Mortgage Loans to a successor servicer. The provisions of

or the Depositor may have under other provisions of this Agreement or otherwise,
whether in equity or at law, such as an action for damages, specific performance
or injunctive relief.

                     WELLS FARGO & COMPANY MASTER GUARANTEE
                 AGREEMENT REGARDING CUSTODIAL P&I ACCOUNT FUNDS


      THIS MASTER GUARANTEE AGREEMENT (the "Guarantee") dated as of May 1, 1999
is entered into by Wells Fargo & Company ("Wells Fargo"), a Delaware
corporation, in favor of each trustee now or hereafter acting in such capacity
for the benefit of the certificateholders of each outstanding and future series
of Wells Fargo Asset Securities Corporation mortgage backed securities
transactions (collectively, the "MBS Transactions"), including without
limitation the trustees identified in Paragraph 8 hereof, and any successor
trustee, all of which trustees are referred collectively in this Guarantee as
the "Trustee."

      WHEREAS, this Guarantee has been required by Standard & Poor's, Fitch,
Inc., Duff & Phelps Credit Rating Co. and Moody's Investors Service, Inc.
(collectively, the "Rating Agencies") (each of which has assigned ratings to
certain of the classes issued in certain of the MBS Transactions) in connection
with their agreement to permit Wells Fargo Bank, N.A., as servicer in the MBS
Transactions (in such capacity, "Servicer"), to hold among Servicer's general
corporate funds for a period of time principal and interest payments, insurance
proceeds, liquidation proceeds and other amounts received by Servicer pertaining
to the mortgage loans underlying the MBS Transactions serviced by Servicer
(collectively, the "Mortgage Loans").

      WHEREAS, Servicer is an indirect, wholly-owned subsidiary of Wells Fargo,
a bank holding company, and Wells Fargo derives substantial benefit from
Servicer's servicing of the Mortgage Loans pursuant to the terms of a separate
servicing agreement between Wells Fargo Bank, N.A., as master servicer, and
Servicer, as servicer, for each MBS Transaction (each, a "Servicing Agreement").

      WHEREAS, to further induce the Rating Agencies to permit Servicer to
withdraw funds from the Custodial P&I Accounts and commingle such funds with the
general assets of Servicer to be used for general corporate purposes until such
time as such funds are required by the terms of the applicable Servicing
Agreement to be remitted to the related Certificate Account, Wells Fargo has
agreed to guarantee the performance of Servicer's obligation under the Servicing
Agreements to timely remit to the related Certificate Accounts the amounts, if
any, so withdrawn from the Custodial P&I Accounts and so used by Servicer.

      NOW THEREFORE, in consideration of the Rating Agencies' permitting the
described arrangement, and for other good and valuable consideration the receipt
and sufficiency of which Wells Fargo hereby acknowledges, Wells Fargo hereby
agrees for the benefit of each Trustee for the benefit of the certificateholders
of each MBS Transaction as follows:

1.    Defined Terms. Capitalized terms used but not defined in this Guarantee
      shall have the respective meanings ascribed to such terms in each
      Servicing Agreement.

2.    Guarantee of Certain Obligation of Servicer under Servicing Agreement.
      Wells Fargo hereby absolutely, unconditionally and irrevocably guarantees
      to each Trustee for the benefit of the certificateholders of each MBS
      Transaction the full and prompt performance, satisfaction and discharge of
      Servicer's obligation under each Servicing Agreement to remit to the
      related Certificate Account by the time specified in each Servicing
      Agreement amounts, if any, withdrawn by the Servicer from the related
      Custodial P&I Account and commingled with the Servicer's general assets
      (such obligation, the "Servicer's Obligation").

3.    Guarantee Absolute. The liability of Wells Fargo under this Guarantee
      shall be absolute and unconditional irrespective of: (i) any change in the
      time, manner of place of performance of, or in any other term of, the
      Servicer's Obligation; (ii) the avoidance or subordination of any
      Servicer's Obligation, or the invalidity or unenforceability thereof;
      (iii) the waiver, consent, extension, forbearance or granting of any
      indulgence, or other modification or amendment to any obligation of
      Servicer under the Servicing Agreement; including without limitation the
      Servicer's Obligation; (iv) the disallowance under bankruptcy or similar
      laws relating to insolvency applicable to Servicer of all or any portion
      of any claim by the Trustee or certificate holders for the performance,
      satisfaction, and discharge of the Servicer's Obligation; or (v) any other
      circumstance that might otherwise constitute a defense to, or a discharge
      of the Servicer's Obligation (except for an express written release or
      discharge of Servicer by the Trustee), all of the foregoing being
      expressly waived by Wells Fargo as defenses to its obligations under this
      Guarantee.

4.    Waiver. Wells Fargo hereby waives any requirement of promptness,
      diligence, presentment, demand, filing of claims with a court in the event
      of receivership or bankruptcy of Servicer, protest, or notice of protest
      with respect to the Servicer's Obligation, and notice of acceptance of
      this Guarantee.

5.    Reinstatement. Guarantor further agrees that, to the extent that the
      Servicer or the Guarantor makes a payment or payments to the Trustee,
      which payment or payments or any part thereof are subsequently
      invalidated, declared to be fraudulent or preferential, set aside and/or
      required to be repaid to the Servicer or the Guarantor or their respective
      estate, trustee, receiver or any other party under any bankruptcy law,
      state or federal law, common law or equitable cause, then to the extent of
      such payment or repayment, this Guarantee and the advances or part thereof
      which have been paid, reduced or satisfied by such amount shall be
      reinstated and continued in full force and effect as of the date such
      initial payments, reduction or satisfaction occurred.

6.    No Waiver of Rights. No failure or delay on the part of the Trustee or the
      Trust Administrator, if applicable, in exercising any right or remedy
      arising under this Guarantee shall operate as a waiver of the Trustee's
      rights hereunder; nor shall any single or partial exercise of any right
      hereunder preclude any other or further exercise hereunder or the exercise
      of any other right by or on behalf of the Trustee.

7.    Representation and Warranties. Wells Fargo hereby represents and
      warrants to the Trustee as follows:

      (a)   Organization. Wells Fargo is a corporation duly organized, validly

            transact business in each jurisdiction in which such qualification
            is necessary, other than those jurisdictions where the failure to be

      (b)   Authority. Wells Fargo has all requisite corporate power and
            authority to execute and enter into this Guarantee and to perform

            and regulations affecting the rights and remedies of creditors
            generally.

      (c)   No Conflicts. The execution, delivery, and performance of
            this Guarantee by Wells Fargo will not constitute (a) a
            violation or breach of any terms or provisions of Wells
            Fargo's Restated Certificate of Incorporation or by-laws or
            (b) a violation or breach of any terms or provisions of, or

            agreement or other agreement or instrument to which Wells
            Fargo is a party or by which Wells Fargo is bound, or any
