            2. Assignment of Servicing Agreements. The Seller agrees to sell,
and the Company agrees to purchase, the mortgage loans (the "Mortgage Loans")

            Upon payment of the Purchase Price, the Seller shall be deemed to
have transferred, assigned, set over and otherwise conveyed to the Company all
the right, title and interest of the Seller in and to the Mortgage Loans
including all interest and principal received or receivable by the Seller on or
with respect to the Mortgage Loans after the Cut-Off Date (and including
scheduled payments of principal and interest due after the Cut-Off Date but
received by the Seller on or before the Cut-Off Date and Principal Prepayments
received or applied on the Cut-Off Date, but not including payments of principal
and interest due on the Mortgage Loans on or before the Cut-Off Date), together
with all of the Seller's right, title and interest in and to the proceeds of any
related title, hazard, primary mortgage or other insurance policies, the
Seller's right to receive amounts, if any, payable on behalf of any Mortgagor
from the Subsidy Account relating to any Subsidy Loan, all of the Seller's
rights described in Section 2 above, and all other property and rights described
in the first paragraph of Section 2.01(a) of the Pooling and Servicing
Agreement. The Company hereby directs the Seller, and the Seller hereby agrees,
to deliver to the Trustee or Custodian on behalf of the Trustee, all documents,
instruments and agreements required to be delivered by the Company to the
Trustee under the Pooling and Servicing Agreement; including, without
limitation, the documents required to be delivered under Section 2.01(a) of the
Pooling and Servicing Agreement; and upon the occurrence of a Document Transfer
Event, the documents required to be delivered under Section 2.01(b). The Seller
further agrees to deliver such other documents, instruments and agreements as
the Company or the Trustee shall reasonably request.

            4. Representations and Warranties; Covenants. The Seller hereby
represents and warrants to the Company that (i) the Company's representations
and warranties to the Trustee pursuant to Section 2.03(b) of the Pooling and
Servicing Agreement are true and correct, as of the date thereof, and (ii)
Seller has not dealt with any broker, investment banker, agent or other person
(other than the Company and Lehman Brothers Inc.) who may be entitled to any
commission or compensation in connection with the sale of the Mortgage Loans.
The Seller hereby agrees to cure any breach of such representations and
warranties in accordance with the terms of the Pooling and Servicing Agreement.

            The Seller hereby agrees to continue to pay on behalf of the Company
and its successors and assignees, promptly as they become due, any lender-paid
primary mortgage insurance premiums ("LPMI Premiums") with respect to any
lender-paid primary mortgage insurance policy (an "LPMI Policy") on each
Mortgage Loan so insured as of the Cut-Off Date, until such Mortgage Loan has
been paid in full or otherwise liquidated; provided, however, that the foregoing
obligation of the Seller shall terminate with respect to all such Mortgage Loans
in the event that either (i) another entity acceptable to the insurers of such
LPMI Policies (the "LPMI Insurers") and the rating agencies rating the
Certificates undertakes to pay such LPMI Premiums, or (ii) the Seller pays
one-time premiums to such LPMI Insurers such that all outstanding LPMI Policies
will remain in force until the related Mortgage Loans have been paid in full or
otherwise liquidated, without the requirement of any further premium payments.

            5. Repurchase or Substitution. (a) The Seller hereby agrees to
repurchase any Mortgage Loan (i) for which any document is not delivered, as
provided in paragraph 3 above, (ii) which is found by the Trustee or the
Custodian to be defective in any material respect, as provided in the Pooling
and Servicing Agreement, or (iii) which is discovered at any time not to be in
conformance with the representations and warranties referred to in paragraph 4
above and which document relating thereto the Seller does not deliver or which
defect or breach the Seller does not cure (as provided in paragraph 4 above)
within 60 days after the date of notice thereof from the Trustee or the Company,
at a price equal to the Repurchase Price. In addition, the Seller hereby agrees
to reimburse the Company for any Reimbursement Amount. Alternatively, the Seller
hereby agrees, if so requested by the Company to substitute for any such
Mortgage Loan, a new mortgage loan having characteristics such that the
representations and warranties referred to in paragraph 4 above would not have
been incorrect (except for representations and warranties as to the correctness
of the Mortgage Loan Schedule) had such substitute mortgage loan originally been
a Mortgage Loan. The Seller further agrees that a substituted mortgage loan will
have (i) an unpaid principal balance no greater than the Scheduled Principal
Balance of the Mortgage Loan for which it is substituted (after giving effect to
the scheduled principal payment due in the month of substitution on the Mortgage
Loan for which such mortgage loan is substituted), (ii) a Net Mortgage Interest
Rate equal to and a Loan-to-Value Ratio no greater than, that of the Mortgage
Loan for which it is substituted, (iii) the same Gross Margin and Index as that
of the Mortgage Loan for which it is substituted and (iv) the same frequency of
mortgage rate adjustment as that of the Mortgage Loan for which it is
substituted. The Seller shall remit to the Company, in cash, the difference
between the unpaid principal balance of the Mortgage Loan to be substituted and
the unpaid principal balance of the substitute mortgage loan.

            (b) In the event that the Seller has a right against the originator
or former owner (the "Prior Holder") of a Mortgage Loan which is in default or
as to which default is reasonably foreseeable for breach of a representation or
warranty regarding the characteristics of such Mortgage Loan made by the Prior
Holder, the Seller may request the Company to repurchase the Mortgage Loan from
the Trust Estate pursuant to Section 3.08 of the Pooling and Servicing Agreement
and the Seller agrees that at the time of the repurchase by the Company, the
Seller will repurchase the Mortgage Loan from the Company at a price equal to
the Repurchase Price.

            At the time of any such repurchase by the Seller, the Seller agrees
either to promptly (i) liquidate such Mortgage Loan, to the extent that the
Seller's rights in respect of the Prior Holder consist of a claim for indemnity
or (ii) transfer such Mortgage Loan to the Prior Holder at a price not less than
that paid by the Seller to the Company.

            6. Underwriting. The Seller hereby agrees to furnish any and all
information, documents, certificates, letters or opinions with respect to the
Mortgage Loans, reasonably requested by the Company in order to perform any of
its obligations or satisfy any of the conditions on its part to be performed or
satisfied pursuant to the Underwriting Agreement at or prior to the Closing
Date.

            7. Costs. The Company shall pay all expenses incidental to the
performance of its obligations under the Underwriting Agreement, including
without limitation (i) any recording fees or fees for title policy endorsements
and continuations, (ii) the expenses of preparing, printing and reproducing the
Prospectus, the Prospectus Supplement, the Underwriting Agreement, the Pooling
and Servicing Agreement and the Certificates and (iii) the cost of delivering
the Class A Certificates to Lehman Brothers Inc. (or its designee) insured to
the satisfaction of Lehman Brothers Inc.

            8. Servicing. (a) The Seller hereby represents to the Company that
the Mortgage Loans are serviced by the Servicers. The Seller has delivered
copies of each Servicing Agreement to the Company, though omitting schedules of
mortgage loans which are serviced thereunder, but which are not being sold in
this transaction.

            (b) With respect to each Mortgage Loan, the Servicing Fee Rate and
the Master Servicing Fee Rate (which is in addition to the Servicing Fee Rate)
shall be as set forth on the Mortgage Loan Schedule.

            (c) On the Closing Date, the Seller shall assign to the Company its
interest with respect to the Mortgage Loans in, to and under each Servicing
Agreement.

            9. Notices. All demands, notices and communications hereunder shall
be in writing, shall be effective only upon receipt and shall, if sent to the
Company, be addressed to it at Wells Fargo Asset Securities Corporation, 5325
Spectrum Drive, Frederick, Maryland 21703, Attn: Vice President, Structured
Finance, or, if sent to the Seller, be addressed to it at Wells Fargo Bank,
N.A., 5325 Spectrum Drive, Frederick, Maryland, 21703, Attn: Vice President,
Structured Finance.

            10. Trustee Beneficiary. The representations, warranties and
agreements made by the Seller in this Agreement are made for the benefit of, and
may be enforced by, the Trustee and the holders of Certificates to the same
extent that the Trustee and the holders of Certificates, respectively, have
rights against the Company under the Pooling and Servicing Agreement in respect
of representations, warranties and agreements made by the Company therein.

            11. Recharacterization. The parties hereto intend the conveyance by
the Seller to the Company of all of its right, title and interest in and to the
Mortgage Loans pursuant to this Agreement to constitute a purchase and sale and
not a loan. Notwithstanding the foregoing, to the extent that such conveyance is
held not to constitute a sale under applicable law, it is intended that this
Agreement shall constitute a security agreement under applicable law and that
the Seller shall be deemed to have granted to the Company a first priority
security interest in all of the Seller's right, title and interest in and to the
Mortgage Loans.

            12. Miscellaneous. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York. Neither this Agreement nor
any term hereof may be changed, waived, discharged or terminated except by a
writing signed by the party against whom enforcement of such change, waiver,
discharge or termination is sought. This Agreement may not be changed in any
manner which would have a material adverse effect on holders of Certificates
without the prior written consent of the Trustee. The Trustee shall be protected
in consenting to any such change to the same extent provided in Article VIII of
the Pooling and Servicing Agreement. This Agreement may be signed in any number
of counterparts, each of which shall be deemed an original, which taken together
shall constitute one and the same instrument. This Agreement shall bind and
inure to the benefit of and be enforceable by the Company and the Seller and
their respective successors and assigns.

            IN WITNESS WHEREOF, the Company and the Seller have caused this
Agreement to be duly executed by their respective officers as of the day and
year first above written.

7) Other Provisions:

(a)   Fully-Paid Party Protected. Notwithstanding the terms of Sections 5 and 6
of the Agreement, if Party B has satisfied in full all its payment obligations
under Section 2(a)(i) of the Agreement, then unless Party A is required pursuant
to appropriate proceedings to return to Party B or otherwise returns to Party B
upon demand of Party B any portion of such payment, (a) the occurrence of an
event described in Section 5(a) (other than Section (a)(vii)) of the Agreement
with respect to Party B or any Credit Support Provider or Specified Entity of
Party B shall not constitute an Event of Default or Potential Event of Default
with respect to Party B as the Defaulting Party and (b) Party A shall be
entitled to designate an Early Termination Event pursuant to Section 6 of the
Agreement only as a result of a Termination Event set forth in either Section
5(b)(i) or Section 5(b)(ii) of the Agreement with respect to Party A as the
Affected Party or Section 5(b)(iii) of the Agreement with respect to Party A as
the Burdened Party. For purposes of the Transaction to which this Confirmation

to which the Trust was formed, in the exercise of the powers and authority
conferred upon and vested in it, and pursuant to instructions set forth therein,
(ii) each of the representations, undertakings and agreements by Wells Fargo
Bank, National Association is made and intended not as a personal
representation, undertaking or agreement of Wells Fargo Bank, National
Association, but solely for the purpose of binding only the Trust, (iii) nothing
herein contained shall be construed as imposing any liability upon Wells Fargo
Bank, National Association, individually or personally, to perform any covenant
(either express or implied) contained herein, and all such liability, if any, is
hereby expressly waived by the parties hereto, and such waiver shall bind any
third party making a claim by or through one of the parties hereto, and (iv)
under no circumstances shall Wells Fargo Bank, National Association be
personally liable for the payment of any indebtedness or expenses of the Trust,
or be liable for the breach or failure of any obligation, representation,
warranty or covenant made or undertaken by the Trust under this Confirmation,
the Agreement or any related document.

Certificates, provided that nothing herein will preclude, or be deemed to estop,
Party A from taking any action in any case or proceeding voluntarily filed or
commenced by or on behalf of Party B or in any involuntary case or proceeding
pertaining to Party B after it has been commenced.

(d)   Set-Off. Notwithstanding any provision of this Agreement or any other
existing or future agreement, each party irrevocably waives any and all rights
it may have to set off, net, recoup or otherwise withhold or suspend or
condition payment or performance of any obligation between it and the other
party hereunder against any obligation between it and the other party under any
other agreements. The provisions for Set-off set forth in Section 6(e) of the
Agreement shall not apply for purposes of this Transaction, provided that
nothing herein shall be construed to waive or otherwise limit the netting
provisions contained in Section 2(c) or 6(e) of this Agreement.

(e)   Severability. If any term, provision, covenant, or condition of this
Agreement, or the application thereof to any party or circumstance, shall be
held to be invalid or unenforceable (in whole or in part) for any reason, the
remaining terms, provisions, covenants, and conditions hereof shall continue in
full force and effect as if this Agreement had been executed with the invalid or
unenforceable portion eliminated, so long as this Agreement as so modified
continues to express, without material change, the original intentions of the
parties as to the subject matter of this Agreement and the deletion of such
portion of this Agreement will not substantially impair the respective benefits
or expectations of the parties.

The parties shall endeavor to engage in good faith negotiations to replace any
invalid or unenforceable term, provision, covenant or condition with a valid or
enforceable term, provision, covenant or condition, the economic effect of which
comes as close as possible to that of the invalid or unenforceable term,
provision, covenant or condition.

      respect to Party A as the sole Affected Party:

      10% or more and less than 20% when the 10% Disclosure Request (as defined
      below) is made or reaches 10% after a 10% Disclosure Request has been made
      to Party A, Party A must comply with the provisions set forth in clauses
      (ii) and (iii) of Paragraph 7(g) below within 3 calendar days of Party A
      being informed of the significance percentage reaching 10% or more), then

      below) complied with the provisions set forth in clauses (iv) and (v) of
      Paragraph 7(g) below (provided that if the significance percentage is 20%
      or more when the 20% Disclosure Request is made or reaches 20% after a 20%
      Disclosure Request has been made to Party A, Party A must comply with the
      provisions set forth in clauses (iv) and (v) of Paragraph 7(g) below
      within 3 calendar days of Party A being informed of the significance
      percentage reaching 20% or more), then an Additional Termination Event
      shall have occurred with respect to Party A and Party A shall be the sole
      Affected Party with respect to such Additional Termination Event.

(g)   Compliance with Regulation AB

      (i) Party A acknowledges that for so long as there are reporting
      obligations with respect to this Transaction under Regulation AB, the
      Depositor, acting on behalf of the Issuing Entity, is required under
      Regulation AB under the Securities Act of 1933, as amended, and the
      Securities Exchange Act of 1934, as amended ("Regulation AB"), to disclose
      certain information set forth in Regulation AB regarding Party A or its
      group of affiliated entities, if applicable, depending on the aggregate
      "significance percentage" of this Agreement and any other derivative
      contracts between Party A or its group of affiliated entities, if
      applicable, and Party B, as calculated from time to time in accordance
      with Item 1115 of Regulation AB.

      (ii) If the Depositor determines, reasonably and in good faith, that the
      significance percentage of this Agreement (and any other derivative
      contracts between Party A or its group of affiliated entities, if
      applicable, and Party B) has increased to eight (8) percent or more but
      less than eighteen (18) percent, then the Depositor may request on the
      date of such determination (or, if such date of determination is not a
      Business Day, the immediately following Business Day) from Party A the
      same information set forth in Item 1115(b)(1) of Regulation AB that would
      have been required if the significance percentage had in fact increased to
      ten (10) percent, along with any necessary auditors' consent (such
      request, a "10% Disclosure Request" and such requested information,
      subject to the last sentence of this paragraph, is the "10% Financial
      Disclosure"). Party B or the Depositor shall provide Party A with the
      calculations and any other information reasonably requested by Party A
      with respect to the Depositor's determination that led to the 10%
      Disclosure Request. The parties hereto further agree that the 10%
      Financial Disclosure provided to meet the 10% Disclosure Request may be,
      solely at Party A's option, either the information set forth in Item
      1115(b)(1) or Item 1115(b)(2) of Regulation AB.

      (iii) Upon the occurrence of a 10% Disclosure Request, Party A, at its own
      expense, shall (i) provide the Depositor with the 10% Financial
      Disclosure, (ii) secure another entity to replace Party A as party to this
      Agreement on terms substantially similar to this Agreement which entity is
      able to (A) provide the 10% Financial Disclosure and (B) provide an
      indemnity to the Depositor, reasonably satisfactory to the Depositor, in
      relation to the 10% Financial Disclosure, (iii) obtain a guaranty of Party
      A's obligations under this Agreement from an affiliate of Party A that is
      able to (A) provide the 10% Financial Disclosure, such that disclosure
      provided in respect of the affiliate will, in the judgment of counsel to
      the Depositor, satisfy any disclosure requirements applicable to Party A,
      and cause such affiliate to provide 10% Financial Disclosure and (B)
      provide an indemnity to the Depositor, reasonably satisfactory to the
      Depositor, in relation to the 10% Financial Disclosure or (iv) deliver
      collateral pursuant to an ISDA Credit Support Annex (subject to New York
      Law) in an amount sufficient to reduce the "significance percentage"
      (determined by the Depositor) below the requirements of Item 1115(b)(1) of
      Regulation AB. Any such 10% Financial Disclosure provided pursuant to this
      paragraph (iii) shall be in a form suitable for conversion to the format
      required for filing by the Depositor with the Securities and Exchange
      Commission via the Electronic Data Gathering and Retrieval System (EDGAR).
      If permitted by Regulation AB, any required 10% Financial Disclosure may
      be provided by incorporation by reference from reports filed pursuant to
      the Securities Exchange Act. For the purpose of this Section 7(g)(iii) and
      subject to the provisions of this Section 7(g)(iii), notwithstanding
      Section 7 of the ISDA Form, no consent of Party B will be required for an
      assignment of this Agreement by Party A pursuant to clause (ii) of this
      Section 7(g)(iii).

      (iv) If the Depositor determines, reasonably and in good faith, that the
      significance percentage of this Agreement (and any other derivative
      contracts between Party A or its group of affiliated entities, if
      applicable, and Party B) has increased to eighteen (18) percent or more,
      then the Depositor may request on the date of such determination (or, if
      such date of determination is not a Business Day, the immediately
      following Business Day) from Party A the same information set forth in
      Item 1115(b)(2) of Regulation AB that would have been required if the
      significance percentage had in fact increased to twenty (20) percent,
      along with any necessary auditors consent (such request, a "20% Disclosure
      Request" and such requested information is the "20% Financial
      Disclosure"). Party B or the Depositor shall provide Party A with the
      calculations and any other information reasonably requested by Party A
      with respect to the Depositor's determination that led to the 20%
      Disclosure Request.

      (v) Upon the occurrence of a 20% Disclosure Request, Party A, at its own
      expense, shall (i) provide the Depositor with the 20% Financial
      Disclosure, (ii) secure another entity to replace Party A as party to this
      Agreement on terms substantially similar to this Agreement which entity is
      able to (A) provide the 20% Financial Disclosure and (B) provide an
      indemnity to the Depositor, reasonably satisfactory to the Depositor, in
      relation to the 20% Financial Disclosure, (iii) obtain a guaranty of Party
      A's obligations under this Agreement from an affiliate of Party A that is
      able to (A) provide the 20% Financial Disclosure, such that disclosure
      provided in respect of the affiliate will, in the judgment of counsel to
      the Depositor, satisfy any disclosure requirements applicable to Party A,
      and cause such affiliate to provide 20% Financial Disclosure and (B)
      provide an indemnity to the Depositor, reasonably satisfactory to the
      Depositor, in relation to the 20% Financial Disclosure or (iv) deliver
      collateral pursuant to an ISDA Credit Support Annex (subject to New York
      Law) in an amount sufficient to reduce the "significance percentage"
      (determined by the Depositor) below the requirements of Item 1115(b)(2) of
      Regulation AB. Any such 20% Financial Disclosure provided pursuant to this
      paragraph (v) shall be in a form suitable for conversion to the format
      required for filing by the Depositor with the Securities and Exchange
      Commission via the Electronic Data Gathering and Retrieval System (EDGAR).
      If permitted by Regulation AB, any required 20% Financial Disclosure may
      be provided by incorporation by reference from reports filed pursuant to
      the Securities Exchange Act. For the purpose of this Section 7(g)(v) and
      subject to the provisions of this Section 7(g)(v), notwithstanding Section
      7 of the ISDA Form, no consent of Party B will be required for an
      assignment of this Agreement by Party A pursuant to clause (ii) of this
      Section 7(g)(v).
