Goldman, Sachs & Co.
85 Broad Street
New York, New York 10004

Ladies and Gentlemen:

Wells Fargo Asset Securities Corporation, a Delaware corporation ("WFASC" or the "Seller") proposes to issue and sell from time to time its Asset-Backed Certificates in various series, each series of which may be divided into classes, in one or more offerings on terms determined at the time of sale. One or more series of Asset-Backed Certificates may be offered through you, as underwriter (the "Underwriter"). Whenever WFASC determines to make an offering of a series of its Asset-Backed Certificates through the Underwriter, WFASC and Wells Fargo Bank, N.A., a national banking association (in such capacity, "Wells Fargo Bank"), will enter into an agreement (the "Terms Agreement") with the Underwriter, in substantially the form attached hereto as Exhibit A, providing for the sale of such series of Asset-Backed Certificates to the Underwriter. WFASC is a wholly-owned subsidiary of Wells Fargo Bank. The Asset-Backed Certificates of the series and classes to be sold in each offering to the Underwriter under this Underwriting Agreement, as supplemented by the applicable Terms Agreement, are hereinafter referred to as the "Certificates." The Asset-Backed Certificates of the same series that are not being sold in each offering to the Underwriter under this Underwriting Agreement are hereinafter referred to as the "Other Certificates." The Certificates will have the characteristics set forth in the applicable Terms Agreement and will evidence the ownership interests in a trust consisting of a pool of mortgage loans acquired by WFASC (the "Mortgage Loans") and related property (collectively, the "Trust Fund"). The Mortgage Loans will be of the type described in, and will have the characteristics and aggregate principal balance set forth in, the Issuer Free Writing Prospectus and the Prospectus (in each case as hereinafter defined).

The Certificates will be issued pursuant to a pooling and servicing agreement (the "Pooling and Servicing Agreement"), dated as of the close of business on the date specified in the applicable Terms Agreement as the closing date (such date, the "Closing Date"), by and among WFASC, as depositor, Wells Fargo Bank, as servicer (in such capacity, the "Servicer"), the trustee identified in the applicable Terms Agreement, as trustee (the "Trustee"), if applicable, the securities administrator identified in the applicable Terms Agreement, as securities administrator (the "Securities Administrator") and, if applicable, the credit risk manager identified in the applicable Terms Agreement as the credit risk manager (the "Credit Risk Manager"). The Certificates will be issued in denominations of $25,000, or such lesser or greater amounts as may be specified in the applicable Terms Agreement, and will have the terms set forth in the Issuer Free Writing Prospectus and the Prospectus. The Certificates will conform in all material respects to the description thereof contained in the applicable Terms Agreement, the Issuer Free Writing Prospectus and the Prospectus. Each offering of Asset-Backed Certificates under this Underwriting Agreement will be governed by this Underwriting Agreement as supplemented by the applicable Terms Agreement. This Underwriting Agreement, as supplemented by the applicable Terms Agreement, is referred to herein as this "Agreement".

1. Representations and Warranties. (a) WFASC represents and warrants to, and agrees with, the Underwriter as of the date of the applicable Terms Agreement that:

(i) A registration statement (with the file number set forth in the related Terms Agreement), including a prospectus (the "Base Prospectus"), has been filed with the Securities and Exchange Commission (the "Commission") and has become effective under the Securities Act of 1933, as amended (the "Act"), was declared effective by the Commission within three years of the Closing Date and no stop order suspending the effectiveness of such registration statement has been issued and no proceedings for that purpose have been initiated or, to WFASC's knowledge, threatened by the Commission; and the Base Prospectus in the form in which it will be used in connection with the offering of the Certificates is proposed to be supplemented by a prospectus supplement relating to the Certificates and, as so supplemented, to be filed with the Commission pursuant to Rule 424 under the Act. (Such registration statement, as amended to the date of the applicable Terms Agreement, is hereinafter referred to as the "Registration Statement"; such prospectus supplement, as first filed with the Commission, is hereinafter referred to as the "Prospectus Supplement"; and such Base Prospectus, in the form in which it will first be filed with the Commission in connection with the offering of the Certificates, as supplemented by the Prospectus Supplement, is hereinafter referred to as the "Prospectus").

(ii) The Registration Statement and the Prospectus, as of the date of the Prospectus Supplement, will conform, and the Registration Statement and the Prospectus, as revised, amended or supplemented and filed with the Commission prior to the termination of the offering of the Certificates, as of their respective effective or issue dates, will conform in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder applicable to such documents as of such respective dates, and the Registration Statement and the Prospectus, as revised, amended or supplemented and filed with the Commission as of the Closing Date, will conform in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder applicable to such documents; and the Registration Statement and the Prospectus, as of the date of the Prospectus Supplement, will not include any untrue statement of a material fact and will not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and, in the case of the Prospectus, as revised, amended or supplemented and filed prior to the Closing Date, as of the Closing Date, will not include any untrue statement of a material fact and will not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that WFASC makes no representations, warranties or agreements as to the information contained in or omitted from the Prospectus or any revision or amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to WFASC by or on behalf of the Underwriter specifically for use in connection with the preparation of the Registration Statement , the Prospectus or the Time of Sale Information (as defined in Section 7(f) below) or any revision or amendment thereof or supplement thereto. The Time of Sale Information, as amended or supplemented, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in either case at the Time of Sale (as defined in Section 7(f) below) to the applicable investor; provided, however, that WFASC makes no representations, warranties or agreements as to the information contained in or omitted from the Time of Sale Information or any revision or amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to WFASC by or on behalf of the Underwriter specifically for use in connection with the preparation of the Registration Statement, the Prospectus or the Time of Sale Information or any revision or amendment thereof or supplement thereto.

(iii) Assuming that it is rated at the time of issuance in one of the two highest rating categories by a nationally recognized statistical rating organization, each Certificate designated as a "mortgage related security" in the Prospectus will, at the time of issuance, be a "mortgage related security," as such term is defined in Section 3(a)(41) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

(iv) Each of the Certificates will conform in all material respects to the description thereof contained in the Issuer Free Writing Prospectus and the Prospectus, and each of the Certificates, when validly authenticated, issued and delivered in accordance with the Pooling and Servicing Agreement, will be duly and validly issued and outstanding and entitled to the benefits of the Pooling and Servicing Agreement, and immediately prior to the delivery of the Certificates to the Underwriter, WFASC will own the Certificates, and upon such delivery the Underwriter will acquire title thereto, free and clear of any lien, pledge, encumbrance or other security interest other than one created or granted by the Underwriter or permitted by the Pooling and Servicing Agreement.

(v) This Agreement has been duly authorized, executed and delivered by WFASC and, as of the Closing Date, the Pooling and Servicing Agreement will have been duly authorized, executed and delivered by WFASC and will conform in all material respects to the description thereof contained in the Issuer Free Writing Prospectus and the Prospectus and, assuming the valid execution thereof by the other parties thereto, will constitute a valid and binding agreement of WFASC enforceable in accordance with its terms, except as the same may be limited by bankruptcy, insolvency, reorganization or other laws relating to or affecting the enforcement of creditors' rights and by general equity principles.

(vi) WFASC has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware with corporate power and authority to own its properties and conduct its business as described in the Issuer Free Writing Prospectus and the Prospectus and to enter into and perform its obligations under the Pooling and Servicing Agreement and this Agreement.

(vii) Neither the issuance or delivery of the Certificates, nor the consummation of any other of the transactions contemplated herein, nor compliance with the provisions of the Pooling and Servicing Agreement or this Agreement, will conflict with or result in the breach of any material term or provision of the certificate of incorporation or bylaws of WFASC, and WFASC is not in breach or violation of or in default (nor has an event occurred which with notice or lapse of time or both would constitute a default) under the terms of (i) any indenture, contract, lease, mortgage, deed of trust, note agreement or other evidence of indebtedness or other agreement, obligation or instrument to which WFASC is a party or by which it or its properties are bound, or (ii) any law, decree, order, rule or regulation applicable to WFASC of any court or supervisory, regulatory, administrative or governmental agency, body or authority, or arbitrator having jurisdiction over WFASC, or its properties, the default in or the breach or violation of which would have a material adverse effect on WFASC or the ability of WFASC to perform its obligations under the Pooling and Servicing Agreement; and neither the delivery of the Certificates, nor the consummation of any other of the transactions contemplated herein, nor the compliance with the provisions of the Pooling and Servicing Agreement or this Agreement will result in such a breach, violation or default which would have such a material adverse effect.

(viii) No filing or registration with, notice to, or consent, approval, authorization or order or other action of, any court or governmental authority or agency is required for the consummation by WFASC of the transactions contemplated by this Agreement or the Pooling and Servicing Agreement (other than as required under state securities laws or Blue Sky laws, as to which no representations and warranties are made by WFASC), except such as have been, or will have been prior to the Closing Date, obtained under the Act, and such recordations of the assignment of the Mortgage Loans to the Trustee or, if applicable, to the Securities Administrator on behalf of the Trustee, pursuant to the Pooling and Servicing Agreement that have not yet been completed.

(ix) There is no action, suit or proceeding before or by any court, administrative or governmental agency, or other tribunal, domestic or foreign, now pending to which WFASC is a party, or, to the best of WFASC's knowledge, threatened against WFASC, which could reasonably result individually or in the aggregate in any material adverse change in the condition (financial or otherwise), earnings, affairs, regulatory situation or business prospects of WFASC or could reasonably interfere with or materially and adversely affect the consummation of the transactions contemplated herein.

(x) On the Closing Date the representations and warranties made by WFASC in the Pooling and Servicing Agreement will be true and correct in all material respects as of the date made.

(xi) At the time of execution and delivery of the Pooling and Servicing Agreement, WFASC will own the mortgage notes (the "Mortgage Notes") being transferred to the Trust Fund pursuant thereto, free and clear of any lien, mortgage, pledge, charge, encumbrance, adverse claim or other security interest (collectively, "Liens"), except to the extent permitted in the Pooling and Servicing Agreement, and will not have assigned to any person other than the Trust Fund any of its right, title or interest in the Mortgage Notes. WFASC will have the power and authority to transfer the Mortgage Notes to the Trust Fund and to transfer the Certificates to the Underwriter, and, upon execution and delivery to the Trustee of the Pooling and Servicing Agreement, payment by the Underwriter for the Certificates, and delivery to the Underwriter of the Certificates, the Trust Fund will own the Mortgage Notes and the Underwriter will acquire title to the Certificates, in each case free of Liens except to the extent permitted by the Pooling and Servicing Agreement.

(xii) Any taxes, fees and other governmental charges in connection with the execution, delivery and issuance of this Agreement, the Pooling and Servicing Agreement and the Certificates have been or will be paid by WFASC on or prior to the Closing Date, except for fees for recording assignments of mortgage loans to the Trustee or, if applicable, to the Securities Administrator on behalf of the Trustee, pursuant to the Pooling and Servicing Agreement that have not yet been completed, which fees will be paid by WFASC in accordance with the Pooling and Servicing Agreement.

(xiii) The transfer of the Mortgage Loans and the related assets to the Trust Fund on the Closing Date will be treated by WFASC for financial accounting and reporting purposes as a sale of assets and not as a pledge of assets to secure debt.

(xiv) WFASC acknowledges and agrees that (i) the purchase and sale of the Certificates pursuant to this Agreement is an arm's-length commercial transaction between WFASC and Wells Fargo Bank on the one hand, and the Underwriter, on the other, (ii) in connection therewith and with the process leading to such transaction, the Underwriter is acting solely as a principal and not the agent or fiduciary of WFASC, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of WFASC with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising WFASC on other matters) or any other obligation to WFASC except the obligations expressly set forth in this Agreement and (iv) WFASC has consulted its own legal advisors to the extent it deemed appropriate.

In connection with such offering(s), the Underwriter agrees to provide WFASC with information related to the offer and sale of the Certificates that is reasonably requested by WFASC, from time to time (but not in excess of three years from the Closing Date), and necessary for complying with its tax reporting obligations, including, without limitation, the issue price of the Certificates.

(b) The Underwriter agrees that it will not sell or transfer any Certificate or interest therein in the initial sale or transfer of such Certificate by the Underwriter in an amount less than the minimum denomination for such Certificate to be set forth in the Issuer Free Writing Prospectus and the Prospectus Supplement.

(c) The Underwriter further agrees that (i) if it delivers to an investor the Prospectus in portable document format ("PDF"), upon the Underwriter's receipt of a request from the investor within the period for which delivery of the Prospectus is required, the Underwriter will promptly deliver or cause to be delivered to the investor, without charge, a paper copy of the Prospectus and
(ii) it will provide to WFASC any Underwriter Free Writing Prospectuses (as defined in Section 9(a)), or portions thereof, which WFASC is required to file with the Commission in electronic format and will use reasonable efforts to provide to WFASC such Underwriter Free Writing Prospectuses, or portions thereof, in either Microsoft Word(R) or Microsoft Excel(R) format and not in a PDF, except to the extent that WFASC, in its sole discretion, waives such requirements.

(d) The Underwriter represents and warrants to, and agrees with, WFASC, as of the date of the applicable Terms Agreement and as of the Closing Date, that:

(i) In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a "Relevant Member State"), it has not made and will not make an offer of Certificates to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Certificates which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the relevant implementation date, make an offer of Certificates to the public in that Relevant Member State at any time:

(A) to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;

(C) in any other circumstances which do not require the publication by the issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this representation, the expression an "offer of Certificates to the public" in relation to any Certificates in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Certificates to be offered so as to enable an investor to decide to purchase or subscribe the Certificates, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression "Prospectus Directive" means the European Commission Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

Section 21(1) of the FSMA does not apply to the issuer.

(iii) It has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Certificates in, from or otherwise involving the United Kingdom.

WFASC will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof. Except as otherwise provided in
Section 5(b) hereof, WFASC will not file prior to the termination of such offering any amendment to the Registration Statement or any revision of or supplement to the Prospectus (other than any such amendment, revision or supplement which does not relate to the Certificates) which shall be disapproved by the Underwriter after reasonable notice and review of such filing.

(b) If, at any time when a prospectus relating to the Certificates is required to be delivered under the Act (without regard to reliance on Rule 174 under the Act) (i) any event occurs as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or (ii) it shall be necessary to revise, amend or supplement the Prospectus to comply with the Act or the rules and regulations of the Commission thereunder, WFASC promptly will notify the Underwriter and will, upon request of the Underwriter, or may, after consultation with the Underwriter, prepare and file with the Commission a revision, amendment or supplement which will correct such statement or omission or effect such compliance, and furnish without charge to the Underwriter as many copies as the Underwriter may from time to time reasonably request of an amended Prospectus or a supplement to the Prospectus which will correct such statement or omission or effect such compliance.

(c) WFASC will (i) furnish to the Underwriter and counsel for the Underwriter, without charge, conformed copies of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus relating to the Certificates is required under the Act, as many copies of the Prospectus and any revisions or amendments thereof or supplements thereto as may be reasonably requested, and (ii) file promptly all reports and any definitive proxy or information statements required to be filed by WFASC with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act (as such requirements may be modified pursuant to Section 12(h) of the Exchange Act) subsequent to the date of the Prospectus Supplement and for so long as the delivery of a prospectus is required under applicable law in connection with the offering or sale of the Certificates.

(d) WFASC will, as between itself and the Underwriter, pay all expenses incidental to the performance of its obligations under this Agreement including, without limitation, (i) expenses of preparing, printing, reproducing and filing the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus, the Pooling and Servicing Agreement and the Certificates, (ii) the cost of delivering the Certificates to the Underwriter, insured to the satisfaction of the Underwriter, (iii) the fees charged by (a) securities rating services for rating the Certificates and (b) WFASC's independent accountants in connection with the letters to be delivered pursuant to Section 6(g) hereof, (iv) the fees and expenses of the Trustee, the Securities Administrator, if applicable, and any agent of the Trustee or the Securities Administrator, if applicable, and the fees and disbursements of counsel for the Trustee and the Securities Administrator, if applicable, in connection with the Pooling and Servicing Agreement and the Certificates, and (v) all other costs and expenses incidental to the performance by WFASC of WFASC's obligations hereunder which are not otherwise specifically provided for in this subsection. It is understood that, except as provided in this paragraph (d) and in Sections 7 and 12 hereof, the Underwriter will pay all of its own expenses, including (i) the fees of any counsel to the Underwriter, (ii) any transfer taxes on resale of any of the Certificates by it, (iii) any advertising expenses connected with any offers that the Underwriter may make, (iv) any expenses for the qualification of the Certificates under state securities laws or Blue Sky laws, including filing fees and the fees and disbursements of counsel for the Underwriter in connection therewith and in connection with the preparation of any Blue Sky survey, and (v) any expenses incurred in connection with the preparation and delivery of any Underwriter Free Writing Prospectus and the filing of such Free Writing Prospectus, if required to be filed by Underwriter with the Commission.

(e) So long as any Certificates are outstanding, upon the request of the Underwriter, WFASC will, or will cause the Servicer to, furnish to the Underwriter, as soon as available, a copy of (i) the annual statement of compliance delivered by the Servicer to the Trustee or the Securities Administrator under the Pooling and Servicing Agreement, (ii) the annual independent public accountants' servicing report furnished to the Trustee or the Securities Administrator pursuant to the Pooling and Servicing Agreement, (iii) each report of WFASC regarding the Certificates filed with the Commission under the Exchange Act or mailed to the holders of the Certificates, and (iv) from time to time, such other information concerning the Certificates which may be furnished by WFASC or the Servicer without undue expense and without violation of applicable law.

(f) If the third anniversary of the effective date of the Registration Statement occurs within six months after the Closing Date, the Company will, at the request of the Underwriter, use reasonable efforts to take such action as may be necessary or appropriate to permit the public offering and sale of the Certificates as contemplated herein.

(xii) Assuming that it is rated at the time of issuance in one of the two highest rating categories by a nationally recognized statistical rating organization, each Certificate designated as a "mortgage related security" in the Prospectus will, at the time of issuance, be a "mortgage related security" as such term is defined in Section 3(a)(41) of the Exchange Act.

Such opinion may express its reliance as to factual matters on the representations and warranties made by, and on certificates or other documents furnished by officers of, the parties to this Agreement and the Pooling and Servicing Agreement. Such opinion may assume the due authorization, execution and delivery of the instruments and documents referred to therein by the parties thereto other than WFASC. Such opinion may be qualified as an opinion only on the laws of the State of New York, the laws of each state in which the writer of the opinion is admitted to practice law and the federal law of the United States. To the extent that such firm relies upon the opinion of other counsel in rendering any portion of its opinion, the opinion of such other counsel shall be attached to and delivered with the opinion of such firm that is delivered to the Underwriter.

(e) The Servicer shall have furnished to the Underwriter an opinion, dated the Closing Date, of counsel to the Servicer (who may be an employee of the Servicer), to the effect that:

(i) The Servicer has been duly incorporated and is validly existing as a national banking association and has the power and authority to enter into, and to take all action required of it under, the Pooling and Servicing Agreement and the Servicing Agreement (as defined in the Pooling and Servicing Agreement);

(ii) The Pooling and Servicing Agreement and the Servicing Agreement have been duly authorized, executed and delivered by the Servicer and, assuming valid execution and delivery thereof by the other parties thereto, the Pooling and Servicing Agreement and the Servicing Agreement constitute a valid and legally binding agreements of the Servicer, enforceable against the Servicer in accordance with their terms, subject to bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting creditors' rights generally and to general equity principles regardless of whether such enforcement is considered in a proceeding at law or in equity;

(iii) No consent, approval, authorization or order of any federal court or governmental agency or body is required for the consummation by the Servicer of the transactions contemplated by the terms of the Pooling and Servicing Agreement and the Servicing Agreement except any such as may be required under the blue sky laws of any jurisdiction in connection with the offering, sale or acquisition of the Certificates, any recordations of the assignments of the mortgage loans evidenced by the Certificates pursuant to the Pooling and Servicing Agreement that have not yet been completed and any approvals as have been obtained;

(iv) The consummation by the Servicer of the transactions contemplated by the terms of the Pooling and Servicing Agreement and the Servicing Agreement do not, to the knowledge of such counsel, conflict with or result in a breach or violation of any material term or provision of, or constitute a default under, the charter or bylaws of the Servicer, any indenture or other agreement or instrument to which the Servicer is a party or by which it is bound, any federal statute or regulation applicable to the Servicer or, to the knowledge of such counsel, any order of any federal court, regulatory body, administrative agency or governmental body having jurisdiction over the Servicer; and

(v) To the best knowledge of such counsel after due inquiry, there are no legal or governmental actions, investigations or proceedings pending to which the Servicer is a party, or threatened against the Servicer, (A) asserting the invalidity of the Pooling and Servicing Agreement or the Servicing Agreement or (B) which might materially and adversely affect the performance by the Servicer of its obligations under, or the validity or enforceability of, the Pooling and Servicing Agreement or the Servicing Agreement. For purposes of the foregoing, such counsel may state that it has not regarded any legal or governmental actions, investigations or proceedings to be "threatened" unless the potential litigant or governmental authority has manifested to a member of the law division of Wells Fargo & Company having responsibility for litigation matters involving the servicing activities of the Servicer a present intention to initiate such proceedings.

Such opinion may express its reliance as to factual matters on the representations and warranties made by, and on certificates or other documents furnished by officers of, the parties to the Pooling and Servicing Agreement or Servicing Agreement. Such opinion may assume the due authorization, execution and delivery of the instruments and documents referred to therein by the parties thereto other than the Servicer. Such opinion may be qualified as an opinion only on the federal law of the United States and, with respect to the opinions set forth in paragraph (e)(ii) above, the laws of the State of New York. To the extent that such counsel relies upon the opinion of other counsel in rendering any portion of its opinion, the opinion of such other counsel shall be attached to and delivered with the opinion of such counsel that is delivered to the Underwriter.

(f) The Underwriter shall have received from counsel for the Underwriter such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Certificates, the Registration Statement, the Issuer Free Writing Prospectus and the Prospectus, and such other related matters as the Underwriter may reasonably require.

(g) WFASC shall have delivered to the Underwriter (i) a letter from WFASC's independent accountants, as identified in the applicable Terms Agreement (the "Independent Accountants"), dated as of or prior to the date of first use of the Prospectus Supplement in the form and reflecting the performance of the procedures previously agreed to by WFASC and the Underwriter with respect to numerical and statistical information included in the Prospectus Supplement (other than static pool information, if any, provided pursuant to Item 1105 of Regulation AB under the Act), (ii) a letter from WFASC's Independent Accountants dated as of or prior to the date of first use of the Issuer Free Writing Prospectus in the form and reflecting the performance of the procedures previously agreed to by WFASC and the Underwriter with respect to numerical and statistical information included in the Issuer Free Writing Prospectus (other than static pool information, if any, provided pursuant to Item 1105 of Regulation AB under the Act), (iii) a copy of a letter from WFASC's Independent Accountants, addressed to WFASC, dated as of a date not more than 135 days prior to the date of first use of the Prospectus Supplement, reflecting the performance of the procedures previously agreed to by WFASC and the Independent Accountants with respect to any static pool information after January 1, 2006 which is incorporated into the Prospectus Supplement and (iv) a bring down letter, dated the date of the Prospectus Supplement, from the Independent Accountants with respect to the letter described in clause (iii), which shall be addressed to the Underwriter provided that the Underwriter shall have complied with any reasonable requests of the Independent Accountants as a condition thereto.

(h) Subsequent to the date on which WFASC notifies the Underwriter that WFASC has selected it to underwrite the offering of the Certificates, there shall not have occurred any change, or any development involving a prospective change, in or affecting the business or properties of WFASC which the Underwriter concludes, in the reasonable judgment of the Underwriter, materially impairs the investment quality of the Certificates so as to make it impractical or inadvisable to proceed with the public offering or the delivery of the Certificates as contemplated by the Issuer Free Writing Prospectus and the Prospectus.

(i) The Certificates shall be rated not lower than the required ratings set forth in the applicable Terms Agreement, such ratings shall not have been rescinded and no public announcement shall have been made that any rating of the Certificates has been placed under review (otherwise than for possible upgrading).

(j) The Underwriter shall have received copies of any opinions of counsel to WFASC supplied to the rating organizations relating to certain matters with respect to the Certificates. Any such opinions shall be dated the Closing Date and addressed to the Underwriter or accompanied by reliance letters to the Underwriter or shall state that the Underwriter may rely upon them.

(k) WFASC shall have furnished to the Underwriter such further information, certificates and documents as the Underwriter may have reasonably requested, and all proceedings in connection with the transactions contemplated by this Agreement and all documents incident hereto shall be in all material respects reasonably satisfactory in form and substance to the Underwriter and its counsel.

(l) The Underwriter shall have received a letter from counsel to WFASC, dated the Closing Date, to the effect that in the course of such counsel's review of the Prospectus and discussion of the same with certain officers of WFASC, its accountants and the Underwriter, no facts came to the attention of such counsel that caused such counsel to believe that the Prospectus, as of the date of the Prospectus Supplement, or any revision or amendment thereof or supplement thereto, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of circumstances under which they were made, not misleading; it being understood that such counsel need express no view as to any financial, numerical, statistical, or quantitative data contained in the Prospectus, or any material incorporated by reference in the Prospectus.

(m) The Underwriter shall have received a letter from counsel to WFASC, dated the date of the Closing Date, substantially to the effect that in the course of such counsel's review of the Issuer Free Writing Prospectus and the Time of Sale Information, no facts came to the attention of such counsel that caused such counsel to believe that as of the applicable Time of Sale, the Issuer Free Writing Prospectus when considered in conjunction with the Time of Sale Information, included an untrue statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; it being understood that such counsel need express no view as to any blanks or bracketed items in the Issuer Free Writing Prospectus, or any financial, numerical, statistical or quantitative data contained in or omitted from the Issuer Free Writing Prospectus or any material incorporated by reference in the Issuer Free Writing Prospectus.

(n) The issuance on the Closing Date of the Other Certificates.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, this Agreement and all obligations of the Underwriter hereunder may be canceled at, or at any time prior to, the Closing Date by the Underwriter. Notice of such cancellation shall be given to WFASC in writing, or by telephone or telegraph confirmed in writing.

7. Indemnification and Contribution. (a) WFASC agrees to indemnify and hold harmless the Underwriter and each person who controls the Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they may become subject under the Act, the Exchange Act, or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in the Prospectus, or in any revision or amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus or any Issuer Information contained in any Free Writing Prospectus (other than any Issuer Free Writing Prospectus), or the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, when considered in conjunction with the Time of Sale Information, and provided that such misstatement or omission was not corrected by information subsequently supplied by WFASC to the Underwriter sufficiently prior to the Time of Sale to such investor to reasonably permit the delivery thereof by the Underwriter to such investor, and WFASC agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by it or him in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that WFASC will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to WFASC by or on behalf of the Underwriter specifically for use in connection with the preparation thereof. This indemnity agreement will be in addition to any liability which WFASC may otherwise have.

(b) The Underwriter agrees to indemnify and hold harmless WFASC, its officers who signed the Registration Statement or any amendment thereof, its directors, and each person who controls WFASC within the meaning of either the Act or the Exchange Act, and Wells Fargo Bank, and each person who controls Wells Fargo Bank within the meaning of either the Act or the Exchange Act, (i) to the same extent as the foregoing indemnities from WFASC to the Underwriter, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to WFASC by or on behalf of the Underwriter specifically for use in connection with the preparation of the Prospectus, the Issuer Free Writing Prospectus or any revision or amendment thereof or supplement thereto or (ii) insofar as such losses, claims, damages or liabilities (or actions in respect thereof) are based on, result from or arise out of (A) any untrue statement or alleged untrue statement of a material fact contained in any Underwriter Free Writing Prospectus, or any omission or alleged omission to state in such Underwriter Free Writing Prospectus a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading at the Time of Sale to the applicable investor, when considered in conjunction with the Time of Sale Information; except to the extent that such untrue statements or alleged untrue statements or omissions or alleged omissions are the result of untrue statements in or omissions from any Issuer Information supplied by WFASC to the Underwriter which, in any case, were not corrected by information subsequently supplied by WFASC to the Underwriter sufficiently prior to the Time of Sale to the applicable investor to reasonably permit the delivery thereof by the Underwriter to such investor or (B) any failure by the Underwriter to deliver the Issuer Free Writing Prospectus or the Time of Sale Information to the applicable investor prior to the Time of Sale. This indemnity agreement will be in addition to any liability which the Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this
Section 7, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel selected by such indemnified party and satisfactory to the indemnifying party (or if such indemnified party fails to promptly select counsel following the receipt of the aforesaid notice, with counsel selected by the indemnifying party and satisfactory to such indemnified party), and after receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this
Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation by the indemnified party undertaken with notice to and approval by the indemnifying party.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to (A) in subsection (a)(i) or (b)(i) above in such proportion as is appropriate to reflect both (i) the relative benefits received by WFASC on the one hand and the Underwriter on the other from the offering of the Certificates and (ii) the relative fault of WFASC on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations and (B) in subsection (a)(ii) or (b)(ii) above, in such proportion as is appropriate to reflect the relative fault of the Underwriter on the one hand and WFASC on the other in connection with the actions, statements or omissions that resulted in such losses, claims, damages or liabilities. The relative benefits received by WFASC on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by WFASC bear to the difference between (i) the total price at which the Certificates underwritten by the Underwriter and distributed to the public were offered to the public, and (ii) the portion of the total net proceeds from the offering (before deducting expenses) received by WFASC attributable to the Certificates. The relative fault for the purposes of clauses (A) and (B) above shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact related to information supplied by WFASC or the Underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. WFASC, Wells Fargo Bank and the Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), and with respect to losses, claims, damages or liabilities referred to in subsection (a) or (b) above, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Certificates underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 (f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of WFASC under this Section 7 shall be in addition to any liability which WFASC may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act; and the obligations of the Underwriter under this
Section 7 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to (i) the officers of WFASC who signed the Registration Statement or any amendment thereof, to its directors, and to each person who controls WFASC within the meaning of either the Act or the Exchange Act and (ii) each person who controls Wells Fargo Bank within the meaning of either the Act or the Exchange Act.

(f) As used in this Agreement, "Time of Sale" means, as to any investor in the Certificates, the time at which such investor enters into a Contract of Sale (as defined in Section 9(b)) for the Certificates, or if such Contract of Sale is subsequently terminated and a new Contract of Sale is entered into by mutual agreement between such investor and the applicable Underwriter in a manner sufficient to constitute a reformation of the contract within the contemplation of Section IV.2.c of Securities Act Release 33-8591, such time at which the new Contract of Sale is entered into, and "Time of Sale Information" means all information identified in the applicable Terms Agreement as "Time of Sale Information."

8. Obligations of Wells Fargo Bank. Wells Fargo Bank agrees with the Underwriter, for the sole and exclusive benefit of the Underwriter and each person who controls the Underwriter within the meaning of either the Act or the Exchange Act and not for the benefit of any assignee thereof or any other person or persons dealing with the Underwriter, in consideration of and as an inducement to its agreement to purchase the Certificates from WFASC, to indemnify and hold harmless the Underwriter against any failure by WFASC to perform its obligations to the Underwriter (including its contribution obligation) pursuant to Section 7 hereof; provided, however, that the aggregate liability of Wells Fargo Bank for the foregoing indemnity shall not exceed an amount equal to the aggregate principal amount of the Certificates.

9. Offering Communications; Free Writing Prospectuses. (a) Unless preceded or accompanied by a prospectus satisfying the requirements of Section 10(a) of the Act, the Underwriter shall not convey or deliver any written communication, as defined in Rule 405 under the Act (a "Written Communication"), to any person in connection with the initial offering of the Certificates, unless such Written Communication (i) is made in reliance on and in conformity with Rule 134 under the Act, (ii) constitutes a prospectus satisfying the requirements of Rule 430B under the Act or (iii) constitutes a "free writing prospectus," as defined in Rule 405 under the Act (a "Free Writing Prospectus"). Notwithstanding anything to the contrary contained in this Agreement, without the prior written consent of WFASC, which may be withheld in its sole discretion, the Underwriter shall not convey or deliver in connection with the initial offering of the Certificates, any Free Writing Prospectus unless such Free Writing Prospectus contains only ABS Informational and Computational Material, as defined in Item 1101(a) of Regulation AB under the Act ("ABS Informational and Computational Material"); provided that any such Free Writing Prospectus may also contain a column showing the status of subscriptions for and allotments of the Certificates. The Underwriter shall not convey or deliver any ABS Informational and Computational Material in reliance on Rules 167 and 426 under the Act. Any Free Writing Prospectus prepared by or on behalf of the Underwriter is referred to as an "Underwriter Free Writing Prospectus."

(b) WFASC shall prepare a Free Writing Prospectus (the "Issuer Free Writing Prospectus") and shall deliver such Issuer Free Writing Prospectus to the Underwriter after it files such Issuer Free Writing Prospectus with the Commission and the Underwriter shall not convey or deliver such Issuer Free Writing Prospectus to any person or entity until WFASC has notified the Underwriter that it has completed such filing. Thereafter, the Issuer Free Writing Prospectus may be used by the Underwriter solely in connection with the marketing of the Certificates to institutional investors; provided however, the Underwriter shall not enter into any "contract of sale" with any investor, within the meaning of Rule 159 under the Act (a "Contract of Sale"), with respect to any Certificates, unless prior to the Time of Sale to each investor in the Certificates, the Underwriter shall have delivered to such investor the Issuer Free Writing Prospectus and any additional Time of Sale Information, together with any amendment or supplement thereto supplied by WFASC to the Underwriter sufficiently prior to the Time of Sale to such investor to reasonably permit delivery thereof by the Underwriter to such investor.

(c) (i) The Underwriter shall deliver to WFASC each Underwriter Free Writing Prospectus that contains any "issuer information," as defined in Rule 433(h) under the Act and footnote 271 of Securities Act Release No. 33-8591 ("Issuer Information") if such Underwriter Free Writing Prospectus or the portion thereof consisting of Issuer Information is required to be filed by WFASC with the Commission pursuant to Rule 433 under the Act ("Rule 433").

(ii) Any Underwriter Free Writing Prospectus that is required to be delivered pursuant to Section 9(c)(i) shall be delivered by the Underwriter to WFASC no later than two business days prior to the due date for filing of the Prospectus pursuant to Rule 424(b) under the Act; provided however, that if such Underwriter Free Writing Prospectus contains any information other than ABS Informational and Computational Material, it shall instead be delivered by the Underwriter to WFASC not later than two business days prior to the date of first use of such Free Writing Prospectus.

(iii) Not later than one business day after the Underwriter has determined the final structure of all classes of Certificates, and in no event later than the fourth business day preceding the due date for filing the final Prospectus pursuant to Rule 424(b) under the Act, the Underwriter shall prepare and deliver to WFASC an Underwriter Free Writing Prospectus (which may consist of a term sheet) containing a description of the final structure of the Certificates, irrespective of whether such Underwriter Free Writing Prospectus has been or will be conveyed or delivered by the Underwriter to any investor in the Certificates.

(iv) To facilitate the filing thereof by WFASC, the Underwriter shall provide the Issuer Information contained in any Underwriter Free Writing Prospectus that is required to be delivered to WFASC pursuant to this Section 9(c) in a separate document from the portion of such Free Writing Prospectus which contains information other than Issuer Information.

(d) The Underwriter represents and warrants to WFASC that the Underwriter Free Writing Prospectuses required to be furnished to WFASC by the Underwriter pursuant to Section 9(c) will constitute all Underwriter Free Writing Prospectuses of the type described therein that were furnished to prospective investors by the Underwriter in connection with its offer and sale of the Certificates.

(e) The Underwriter represents and warrants to WFASC that each Underwriter Free Writing Prospectus provided by it to an investor in the Certificates did not, as of the Time of Sale to any prospective investor to which such Underwriter Free Writing Prospectus was conveyed, include any untrue statement of a material fact or omit any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading when considered in conjunction with the Time of Sale Information; provided however, that the Underwriter makes no representation or warranty to the extent such misstatements or omissions were the result of any misstatements in or omissions from any Issuer Information in any Underwriter Writing Prospectus or, to the extent that such misstatements are a substantial restatement in all material respects of a misstatement made in the Issuer Free Writing Prospectus which misstatements or omissions were not corrected by information subsequently supplied by WFASC sufficiently prior to the Time of Sale to the applicable investor to reasonably permit delivery thereof by the Underwriter to such investor.

(f) Unless WFASC determines that such filing is not required under Rule 433, WFASC agrees to file with the Commission, within the applicable time periods specified in Rule 433, the following:

(i) Any Issuer Free Writing Prospectus; and

(ii) Any Underwriter Free Writing Prospectus delivered by the Underwriter to WFASC pursuant to Section 9(c) or, at the election of WFASC, the portion of such Underwriter Free Writing Prospectus which consists of Issuer Information.

(g) The Underwriter shall file with the Commission, within the applicable time period specified in Rule 433, any Free Writing Prospectus that is distributed by or on behalf of the Underwriter in a manner reasonably designed to lead to its broad, unrestricted dissemination. Any access codes or passwords needed by the Underwriter to complete the filing shall be provided by WFASC.

(h) WFASC and the Underwriter each agrees that any Free Writing Prospectuses prepared by it shall contain substantially the following legend:

The depositor has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the depositor and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling toll-free 1-8[xx-xxx-xxxx].

The asset-backed securities referred to in these materials, and the asset pools backing them, are subject to modification or revision (including the possibility that one or more classes of securities may be split, combined or eliminated at any time prior to issuance or availability of a final prospectus) and are offered on a "when, as and if issued" basis. You understand that, when you are considering the purchase of these securities, a contract of sale will come into being no sooner than the date on which the relevant class has been priced and the underwriter has confirmed the allocation of securities to be made to you; any "indications of interest" expressed by you, and any "soft circles" generated by the underwriter, will not create binding contractual obligations for you, the underwriter or us.

(i) The Underwriter agrees to comply with the requirements of Rule 433 under the Act applicable to the Underwriter including, without limitation, the record retention requirements therein.

(j) (i) Consistent with the manner in which written records are maintained for its own purposes, the Underwriter agrees to keep and maintain, for a period of not less than three years following the date of initial issuance of the Certificates, written records documenting, as to each investor in Certificates, the Time of Sale and the date on which each Issuer Free Writing Prospectus and each Underwriter Free Writing Prospectus was conveyed to such investor.

(ii) In the event of any litigation or written notice of potential litigation against WFASC or any of its affiliates with respect to the Certificates, the Underwriter shall, upon the request of WFASC, make available to WFASC copies of all records required to be maintained by it pursuant to
Section 9(j)(i) and any Free Writing Prospectus required to be retained by it pursuant to Section 9(i).

(k) [Reserved]

(l) (i) In the event that WFASC becomes aware that the Issuer Free Writing Prospectus contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading (such Free Writing Prospectus, a "Defective Issuer Free Writing Prospectus"), WFASC shall notify the Underwriter thereof within one business day after discovery and WFASC shall prepare and deliver to the Underwriter a Free Writing Prospectus which corrects the material misstatement or omission in the Defective Issuer Free Writing Prospectus (such corrected Issuer Free Writing Prospectus, a "Corrected Issuer Free Writing Prospectus").

(ii) In the event that the Underwriter becomes aware that, as of the applicable Time of Sale to an investor in the Certificates, any Underwriter Free Writing Prospectus prepared by or on behalf of the Underwriter and delivered to such investor contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading, when considered in conjunction with the Time of Sale Information (such Free Writing Prospectus, a "Defective Underwriter Free Writing Prospectus and, together with a Defective Issuer Free Writing Prospectus, a "Defective Free Writing Prospectus"), the Underwriter shall notify WFASC thereof within one business day after discovery.

(iii) The Underwriter shall, if requested by WFASC:

(A) prepare a Free Writing Prospectus which corrects the material misstatement in or omission from the Defective Underwriter Free Writing Prospectus (such corrected Underwriter Free Writing Prospectus, a "Corrected Underwriter Free Writing Prospectus" and, together with a Corrected Issuer Free Writing Prospectus, a "Corrected Free Writing Prospectus");

(B) deliver the Corrected Free Writing Prospectus to each investor which received the Defective Free Writing Prospectus prior to entering into a Contract of Sale;

(C) provide such investor with the following:

(1) adequate disclosure of the contractual arrangement;

(2) adequate disclosure of the investor's rights under the existing Contract of Sale at the time termination is sought;

(3) adequate disclosure of the new information that is necessary to correct the misstatements or omissions in the information given at the time of the original Contract of Sale; and

(4) a meaningful ability to elect to terminate or not terminate the prior Contract of Sale and to elect to enter into or not enter into a new Contract of Sale; and

(D) comply with any other requirements for reformation of the original Contract of Sale described in Section IV.2.c of Securities Act Release Act 33-8591.

(m) The Underwriter covenants with WFASC that it will make available to WFASC, upon reasonable prior notice and at reasonable times during normal business hours, such personnel as are familiar with the Underwriter's compliance procedures for the purpose of answering questions concerning the Underwriter's practices and procedures for the preparation and dissemination of Written Communications concerning the Certificates to prospective investors prior to the delivery of the final Prospectus to such investors.

(n) The Underwriter covenants with WFASC that after the final Prospectus is available, the Underwriter shall not distribute any Written Communication concerning the Certificates to a prospective investor unless such communication is preceded or accompanied by the final Prospectus.

(o) The Underwriter agrees, upon request of WFASC, to provide to WFASC any information within the control of the Underwriter which WFASC may reasonably request to enable WFASC to timely and accurately meet its disclosure and reporting obligations under the Act and the Exchange Act.

(p) The Underwriter agrees to cause any credit enhancement provider, derivative counterparty, special servicer or credit risk manager arranged by the Underwriter in connection with the Certificates to provide to WFASC such narrative disclosure, financial information, including required accountants' consents, and other information as WFASC may reasonably request to enable WFASC to timely and accurately meet its disclosure and reporting obligations under the Act and the Exchange Act. In addition, upon request by WFASC, the Underwriter agrees to cause the party providing the information required by the immediately preceding sentence to provide indemnity satisfactory to WFASC relating to such disclosure and financial information.

(q) Notwithstanding any other provision herein, the Underwriter and WFASC each agree to pay all costs and expenses of the other party including, without limitation, legal fees and expenses, incurred in connection with any successful action by the Underwriter or WFASC against the other party to enforce any of its rights set forth in this Section 9.

10. Termination. Subsequent to the execution of the applicable Terms Agreement, this Agreement shall be subject to termination in the absolute discretion of the Underwriter, by notice given to WFASC prior to delivery of and payment for the Certificates, if prior to such time (i) trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited or any setting of minimum prices for trading on such exchange shall have been instituted, (ii) a general moratorium on commercial banking activities in the State of New York shall have been declared by either federal or New York State authorities or there shall have occurred a material disruption in securities settlement or clearance services in the United States, or (iii) there shall have occurred any material outbreak or escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the reasonable judgment of the Underwriter, impracticable or inadvisable to market the Certificates on the terms and in the manner contemplated by the Prospectus as amended or supplemented.
