Company all the right, title and interest of Wells Fargo Bank in and to the

after the applicable Cut-off Date but received by Wells Fargo Bank on or before
such Cut-off Date and Principal Prepayments received or applied on the
applicable Cut-off Date, but not including payments of principal and interest

related title, hazard, primary mortgage or other insurance policies, all of
Wells Fargo Bank'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 Wells Fargo Bank, and Wells
Fargo Bank 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). Wells Fargo Bank further agrees to deliver such other
documents, instruments and agreements as the Company or the Trustee shall
reasonably request.

               4. Representations and Warranties; Covenants. Wells Fargo Bank
hereby represents and warrants to the Company that (i) the Company's
representations and warranties to the Trustee pursuant to Section 2.04 of the
Pooling and Servicing Agreement are true and correct, as of the date thereof,
and (ii) Wells Fargo Bank has not dealt with any broker, investment banker,
agent or other person (other than the Company and Barclays Capital Inc.) who may
be entitled to any commission or compensation in connection with the sale of the
Mortgage Loans. Wells Fargo Bank hereby agrees to cure any breach of such
representations and warranties in accordance with the terms of the Pooling and
Servicing Agreement.

               Wells Fargo Bank 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 (other than the Covered Mortgage Loans) so insured as of the
applicable Cut-off Date, until such Mortgage Loan has been paid in full or
otherwise liquidated; provided, however, that the foregoing obligation of Wells
Fargo Bank 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) Wells Fargo Bank 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) Wells Fargo Bank hereby agrees
to repurchase any Mortgage Loan from the Company (i) for which any document is
not delivered, as provided in paragraph 3 above, (ii) which is found by the
Trustee 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 Wells Fargo Bank does not deliver or
which defect or breach Wells Fargo Bank 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 Purchase Price. In addition, Wells Fargo Bank
hereby agrees to reimburse the Company for any Reimbursement Amount.
Alternatively, Wells Fargo Bank 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. Wells Fargo Bank
further agrees that a substituted mortgage loan will meet the requirements of an
Eligible Substitute Mortgage Loan. Wells Fargo Bank 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 addition, Wells Fargo Bank shall pay (i) the amount of any
Prepayment Premium (to the extent not collected and remitted to the Trust) to
the Trust if Wells Fargo Bank is unable to collect a Prepayment Penalty as a
result of its enforceability being found to be limited or prohibited by
applicable law and (ii) without duplication of any amount payable under clause
(i), the amount due to the Trust by Wells Fargo Bank pursuant to the last
paragraph of Section 2.03(a) of the Pooling and Servicing Agreement (any such
amounts, the "Originator Prepayment Penalty Payment Amount"). Wells Fargo Bank
shall remit to the Securities Administrator for deposit into the Collection
Account any Originator Prepayment Penalty Payment Amount by the Servicer
Remittance Date following the month in which a Principal Prepayment was made on
the related Mortgage Loan.

               (c) In the event that Wells Fargo Bank has a right against the
originator or former owner of a Mortgage Loan (the "Prior Holder") for breach of
a representation or warranty regarding the characteristics of such Mortgage Loan
made by the Prior Holder, Wells Fargo Bank may request the Company to repurchase
the Mortgage Loan from the Trust Fund pursuant to Section 2.03 of the Pooling
and Servicing Agreement and Wells Fargo Bank agrees that at the time of the
repurchase by the Company, Wells Fargo Bank will repurchase the Mortgage Loan
from the Company at the "purchase price" paid by the Company pursuant to the
Pooling and Servicing Agreement.

               At the time of any such repurchase by Wells Fargo Bank, Wells
Fargo Bank agrees either to promptly (i) liquidate such Mortgage Loan, to the
extent that Wells Fargo Bank'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 Wells Fargo Bank to the Company.

               6. Underwriting. Wells Fargo Bank 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 or the Purchase
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 and the Purchase
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 Purchase Agreement, the Pooling and Servicing Agreement and the
Certificates and (iii) the cost of delivering the Certificates to the offices of
Barclays Capital Inc. insured to the satisfaction of Barclays Capital Inc.

               8. Servicing. (a) Wells Fargo Bank hereby represents to the
Company that the Mortgage Loans are serviced by the Servicer.

               (b) With respect to each Mortgage Loan, the Servicing Fee Rate
shall be as set forth on the Mortgage Loan Schedule.

               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,
7430 New Technology Way, Frederick, Maryland 21703, Attn: Vice President,
Structured Finance, or, if sent to Wells Fargo Bank, be addressed to it at Wells
Fargo Bank, N.A., 7430 New Technology Way, Frederick, Maryland, 21703, Attn:
Vice President, Structured Finance.

               10. Trustee Beneficiary. The representations, warranties and
agreements made by Wells Fargo Bank 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. 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 Wells Fargo Bank
and their respective successors and assigns.

               12. 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.
