Banc of America Securities LLC
214 North Tryon Street
Charlotte, North Carolina 28255

Ladies and Gentlemen:

      SECTION 1.     Introductory. Banc of America Funding Corporation, a
Delaware corporation (the "Company"), proposes to sell to Banc of America
Securities LLC ("BAS" or the "Underwriter") $941,391,425 aggregate Class
Certificate Balance of its Mortgage Pass-Through Certificates identified in
Schedule I hereto (the "Offered Certificates") having the aggregate initial
Class Certificate Balances set forth in Schedule I (subject to an upward or
downward variance, not to exceed 5%, of the precise initial Class Certificate
Balance within such range to be determined by the Company in its sole
discretion). The Offered Certificates, together with three classes of
subordinate certificates (the "Non-Offered Certificates") are collectively
referred to herein as the "Certificates" and evidence the entire ownership
interest in the assets of a trust estate (the "Trust Estate") consisting
primarily of a pool of fixed interest rate mortgage loans having original terms
to maturity of approximately 180 to approximately 360 months as described in
Schedule I (the "Mortgage Loans") to be acquired by the Company pursuant to a
mortgage loan purchase agreement (the "Mortgage Loan Purchase Agreement"), dated
March 30, 2006, by and between the Company, as purchaser and Bank of America,
National Association, as seller. As of the close of business on the date
specified in Schedule I as the cut-off date (the "Cut-off Date"), the Mortgage
Loans will have the aggregate principal balance set forth in Schedule I. This
Underwriting Agreement shall hereinafter be referred to as the "Agreement."
Elections will be made to treat the assets of the Trust Estate as multiple
separate real estate mortgage investment conduits (each, a "REMIC"). The
Certificates are to be issued pursuant to a pooling and servicing agreement,
dated March 30, 2006 (the "Pooling and Servicing Agreement"), among the Company,
as depositor, Wells Fargo Bank, N.A., as master servicer (the "Master Servicer")
and as securities administrator (the "Securities Administrator"), and U.S. Bank
National Association, as trustee (the "Trustee"). The Offered Certificates will
be issued in the denominations specified in Schedule I. The Pooling and
Servicing Agreement, this




Agreement, the Mortgage Loan Purchase Agreement and the purchase agreement, to
be dated March 30, 2006, between BAS, as purchaser and the Company (the
"Purchase Agreement") are collectively referred to herein as the "Basic
Documents."

      Capitalized terms used herein that are not otherwise defined herein have
the meanings assigned thereto in the Pooling and Servicing Agreement.

      SECTION 2.     Representations and Warranties of the Company. The Company
represents and warrants to the Underwriter as follows:

            (a)   The Company meets the requirements for use of Form S-3 under
      the Securities Act of 1933, as amended (the "Act") and has filed with the
      Securities and Exchange Commission (the "Commission") a registration
      statement on Form S-3 (the file number of which is set forth in Schedule I
      hereto), which has become effective, for the registration under the Act of
      the Offered Certificates. Such registration statement, as amended to the
      date of this Agreement, meets the requirements set forth in Rule 415(a)(l)
      under the Act and complies in all other material respects with Rule
      415(a)(1). The Company proposes to file with the Commission pursuant to
      Rule 424 under the Act a supplement to the form of prospectus included in
      such registration statement relating to the Offered Certificates and the
      plan of distribution thereof and a revised form of prospectus (the
      "Revised Basic Prospectus") with such changes to the form of prospectus
      which appears in the Registration Statement as are necessary to comply
      with the requirements of Regulation AB under the Act (17 C.F.R. Subpart
      229, Items 1100-1123) and has previously advised you of all further
      information (financial and other) with respect to the Company to be set
      forth therein. Such registration statement, including the exhibits
      thereto, as amended to the date of this Agreement, is hereinafter called
      the "Registration Statement"; such prospectus in the form in which it
      appears in the Registration Statement, as revised by the Revised Basic
      Prospectus, is hereinafter called the "Basic Prospectus"; and such
      supplement to the Basic Prospectus, in the form in which it shall be filed
      with the Commission pursuant to Rule 424, is hereinafter called the
      "Prospectus Supplement" and, collectively with the Basic Prospectus, the
      "Final Prospectus." Any reference herein to the Registration Statement,
      the Basic Prospectus or the Final Prospectus shall be deemed to refer to
      and include the documents incorporated by reference therein pursuant to
      Item 12 of Form S-3 which were filed under the Securities Exchange Act of
      1934, as amended (the "Exchange Act"), on or before the date of this
      Agreement, or the issue date of the Basic Prospectus or the Final
      Prospectus, as the case may be; and any reference herein to the terms
      "amend," "amendment" or "supplement" with respect to the Registration
      Statement, the Basic Prospectus or the Final Prospectus shall be deemed to
      refer to and include the filing of any document under the Exchange Act
      after the date of this Agreement, or the issue date of the Basic
      Prospectus or the Final Prospectus, as the case may be, and deemed to be
      incorporated therein by reference.

            (b)   At or prior to the time when sales to investors of the Offered
      Certificates were first made, as set forth in Schedule I hereto (the
      "Pricing Date"), the Company had prepared the information (collectively,
      the "Disclosure Package") listed in Schedule III hereto. If, subsequent to
      the date of this Agreement, the Company or the Underwriter has


                                        2



      determined that such 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 and have terminated their old purchase contracts
      and entered into new purchase contracts with purchasers of the Offered
      Certificates, then "Disclosure Package" will refer to the information
      available to purchasers at the time of entry into the first such new
      purchase contract, including any information that corrects such material
      misstatements or omissions ("Corrective Information").

            (c)   As of the date hereof, when the Final Prospectus is first
      filed pursuant to Rule 424 under the Act, when, prior to the Closing Date
      (as hereinafter defined), any amendment to the Registration Statement
      becomes effective (including the filing of any document incorporated by
      reference in the Registration Statement), when any supplement to the Final
      Prospectus is filed with the Commission and at the Closing Date, (i) the
      Registration Statement, as amended as of any such time, and the Final
      Prospectus, as amended or supplemented as of any such time, will comply in
      all material respects with the Act and the respective rules thereunder,
      (ii) the Registration Statement, as amended as of any such time, will not
      contain any untrue statement of a material fact or omit to state any
      material fact required to be stated therein or necessary in order to make
      the statements therein not misleading, and (iii) the Final Prospectus, as
      amended or supplemented as of any such time, will not contain any untrue
      statement of a material fact or omit to state any material fact required
      to be stated therein or necessary in order to make the statements therein,
      in light of the circumstances under which they were made, not misleading;
      provided, however, that the Company makes no representations or warranties
      as to the information contained in or omitted from the Registration
      Statement or the Final Prospectus or any amendment thereof or supplement
      thereto in reliance upon and in conformity with information furnished in
      writing to the Company by or on behalf of the Underwriter specifically for
      use in connection with the preparation of the Registration Statement or
      the Final Prospectus.

            (d)   The Disclosure Package, at the Pricing Date did not, and at
      the Closing Date will not, contain any untrue statement of a material fact
      or omit 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; provided that the Company makes no representation and warranty
      with respect to the information contained in or omitted from the
      Disclosure Package or any amendment thereof or supplement thereto in
      reliance upon and in conformity with information furnished in writing to
      the Company by or on behalf of the Underwriter specifically for use in
      connection with the preparation of the Disclosure Package.

            (e)   The Company has been duly incorporated and is validly existing
      as a corporation under the laws of the State of Delaware and has corporate
      and other power and authority to own its properties and conduct its
      business, as now conducted by it, and to enter into and perform its
      obligations under this Agreement and the other Basic Documents to which it
      is a party.


                                        3



            (f)   The Company is not aware of (i) any request by the Commission
      for any further amendment of the Registration Statement or the Basic
      Prospectus or for any additional information or (ii) the issuance by the
      Commission of any stop order suspending the effectiveness of the
      Registration Statement or the initiation of any proceedings for that
      purpose by the Commission.

            (g)   This Agreement has been duly authorized, executed and
      delivered by the Company, and each of the other Basic Documents to which
      the Company is a party, when delivered by the Company, will have been duly
      authorized, executed and delivered by the Company, and will constitute a
      legal, valid and binding agreement of the Company, enforceable against the
      Company in accordance with its terms, subject, as to the enforcement of
      remedies, to applicable bankruptcy, insolvency, reorganization,
      moratorium, receivership and similar laws affecting creditors' rights
      generally and to general principles of equity (regardless of whether the
      enforcement of such remedies is considered in a proceeding in equity or at
      law), and except as rights to indemnity and contribution hereunder may be
      limited by federal or state securities laws or principles of public
      policy.

            (h)   The Company is not, and on the date on which the first bona
      fide offer of the Offered Certificates is made will not be, an "ineligible
      issuer," as defined in Rule 405 under the Act.

            (i)   On the Closing Date, the Basic Documents will conform to the
      description thereof contained in the Registration Statement, the Final
      Prospectus and the Disclosure Package; the Offered Certificates will have
      been duly and validly authorized and, when such Offered Certificates are
      duly and validly executed, issued and delivered in accordance with the
      Pooling and Servicing Agreement, and sold to the Underwriter as provided
      herein, will be validly issued and outstanding and entitled to the
      benefits of the Pooling and Servicing Agreement.

            (j)   As of the Closing Date, the representations and warranties of
      the Company set forth in the Pooling and Servicing Agreement will be true
      and correct.

            (k)   Neither the execution and delivery by the Company of this
      Agreement or any other of the Basic Documents nor the consummation by the
      Company of the transactions contemplated herein or therein, nor the
      issuance of the Offered Certificates or the public offering thereof as
      contemplated in the Final Prospectus or the Disclosure Package will
      conflict in any material respect with or result in a material breach of,
      or constitute a material default (with notice or passage of time or both)
      under, or result in the imposition of any lien, pledge, charge, of the
      property or assets of the Company (except as required or permitted
      pursuant thereto or hereto), pursuant to any material mortgage, indenture,
      loan agreement, contract or other instrument to which the Company is party
      or by which it is bound, nor will such action result in any violation of
      any provisions of any applicable law, administrative regulation or
      administrative or court decree, the certificate of incorporation or
      by-laws of the Company. The Company is not in violation of its certificate
      of incorporation, in default in any material respect in the performance or
      observance of any material obligation, agreement, covenant or condition


                                        4



      contained in any contract, indenture, mortgage, loan agreement, note,
      lease, trust agreement, transfer and servicing agreement or other
      instrument to which a party or by which it may be bound, or to which any
      material portion of its property or assets is subject.

            (l)   No legal or governmental proceedings are pending to which the
      Company is a party or of which any property of the Company is subject,
      which if determined adversely to the Company would, individually or in the
      aggregate, have a material adverse effect on the financial position,
      stockholders' equity or results of operations of the Company; and to the
      best of the Company's knowledge, no such proceedings are threatened or
      contemplated by governmental authorities or threatened by others.

            (m)   Since the date of which information is given in the
      Registration Statement, there has not been any material adverse change in
      the business or net worth of the Company.

            (n)   Any taxes, fees and other governmental charges in connection
      with the execution and delivery of the Basic Documents and the execution,
      delivery and sale of the Offered Certificates have been or will be paid at
      or prior to the Closing Date.

            (o)   No consent, approval, authorization or order of, or
      registration, filing or declaration with, any court or governmental agency
      or body is required, or will be required, in connection with (i) the
      execution and delivery by the Company of any Basic Document or the
      performance by the Company of any or (ii) the offer, sale or delivery of
      the Offered Certificates except such as shall have been obtained or made,
      as the case may be, or will be obtained or made, as the case may be, prior
      to the Closing Date, or will not materially adversely affect the ability
      of the Company to perform its obligations under any Basic Document.

            (p)   The Company possesses, and will possess, all material
      licenses, certificates, authorities or permits issued by the appropriate
      state, federal or foreign regulatory agencies or bodies necessary to
      conduct the business now conducted by it and as described in the
      Preliminary Prospectus, if any, Final Prospectus and the Disclosure
      Package, except to the extent that the failure to have such licenses,
      certificates, authorities or permits does not have a material adverse
      effect on the Offered Certificates or the financial condition of the
      Company, and the Company has not received, nor will have received as of
      each Closing Date, any notice of proceedings relating to the revocation or
      modification of any such license, certificate, authority or permit which,
      singly or in the aggregate, if the subject of an unfavorable decision,
      ruling or finding, would materially and adversely affect the conduct of
      its business, operations or financial condition.

            (q)   On the Closing Date, (i) the Company will have good and
      marketable title to the related Mortgage Loans being transferred by it to
      the Trust pursuant thereto, free and clear of any lien, (ii) the Company
      will not have assigned to any person any of its right, title or interest
      in such Mortgage Loans or in the Pooling and Servicing Agreement, and
      (iii) the Company will have the power and authority to sell such Mortgage
      Loans to the Trust, and upon execution and delivery of the Pooling and
      Servicing Agreement by


                                        5



      the Trustee, the Company, the Master Servicer and the Securities
      Administrator, the Trust will have good and marketable title thereto, in
      each case free of liens.

            (r)   The properties and businesses of the Company conform, and will
      conform, in all material respects, to the descriptions thereof contained
      in the Final Prospectus and the Disclosure Package.

            (s)   The Company is not, and, after giving effect to the
      transactions contemplated by the Pooling and Servicing Agreement and the
      offering and sale of the Offered Certificates, neither the Company nor the
      Trust Fund will be, an "investment company", as defined in the Investment
      Company Act of 1940, as amended.

            (t)   It is not necessary in connection with the offer, sale and
      delivery of the Offered Certificates in the manner contemplated by this
      Agreement to qualify the Pooling and Servicing Agreement under the Trust
      Indenture Act of 1939, as amended (the "1939 Act").

            (u)   Other than the Final Prospectus, the Company (including its
      agents and representatives other than the Underwriter) has not made, used,
      prepared, authorized, approved or referred to and will not make, use,
      prepare, authorize, approve or refer to any "written communication" (as
      defined in Rule 405 under the Act) that constitutes an offer to sell or
      solicitation of an offer to buy the Offered Certificates other than (i)
      information included in the Disclosure Package (ii) any document not
      constituting a prospectus pursuant to Section 2(a)(10)(a) of the Act or
      Rule 134 under the Act or (iii) other written communication approved in
      writing in advance by the Underwriter.

            (v)   Any Issuer Free Writing Prospectus included in the Disclosure
      Package complied in all material respects with the Act and has been, or
      will be filed in accordance with Rule 433 under the Act (to the extent
      required thereby).

      SECTION 3.     Purchase, Sale and Delivery of Offered Certificates. On the
basis of the representations, warranties and agreements herein contained, but
subject to the terms and conditions herein set forth, the Company agrees to
issue and sell to the Underwriter, and the Underwriter agrees to purchase from
the Company, the aggregate Class Certificate Balance of Offered Certificates set
forth in Schedule II hereto, at the applicable purchase price set forth in
Schedule I hereto.

      The Company will deliver the Offered Certificates to the Underwriter,
against payment of the applicable purchase price therefor in same day funds
wired to such bank as may be designated by the Company, or by such other manner
of payment as may be agreed upon by the Company and the Underwriter, at the
offices of Hunton & Williams LLP, Charlotte, North Carolina, at 10:00 A.M.,
Eastern time, on March 30, 2006, or at such other place or time not later than
seven full business days thereafter as the Underwriter and the Company
determine, such time being referred to herein as the "Closing Date."

      The Offered Certificates so to be delivered will be in such denominations
and registered in such names as the Underwriter requests two full business days
prior to the Closing Date and will be made available at the offices of Banc of
America Securities LLC, Charlotte, North


                                        6



Carolina or, upon the Underwriter's request, through the facilities of The
Depository Trust Company.

      SECTION 4.     Offering by the Underwriter. It is understood that the
Underwriter proposes to offer the Offered Certificates subject to this Agreement
for sale to the public (which may include selected dealers) on the terms as set
forth in the Final Prospectus.

      SECTION 5.     Covenants of the Company. The Company hereby covenants and
agrees with the Underwriter that:

            (a)   Prior to the termination of the offering of the Offered
      Certificates, the Company will not file any amendment of the Registration
      Statement or supplement (including the Final Prospectus) to the Basic
      Prospectus unless the Company has furnished the Underwriter a copy for
      their review prior to filing and will not file any such proposed amendment
      or supplement to which the Underwriter reasonably objects. Subject to the
      foregoing sentence, the Company will cause the Final Prospectus to be
      filed with the Commission pursuant to Rule 424. The Company will advise
      the Underwriter promptly (i) when the Final Prospectus shall have been
      filed with the Commission pursuant to Rule 424, (ii) when any amendment to
      the Registration Statement relating to the Offered Certificates shall have
      become effective, (iii) of any request by the Commission for any amendment
      of the Registration Statement or amendment of or supplement to the Final
      Prospectus or for any additional information, (iv) of the issuance by the
      Commission of any stop order suspending the effectiveness of the
      Registration Statement or the institution or threatening of any proceeding
      for that purpose and (v) of the receipt by the Company of any notification
      with respect to the suspension of the qualification of the Offered
      Certificates for sale in any jurisdiction or the initiation or threatening
      of any proceeding for such purpose. The Company 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.

            (b)   If, at any time when a prospectus relating to the Offered
      Certificates is required to be delivered under the Act, any event occurs
      as a result of which the Final Prospectus as then amended or supplemented
      would include any untrue statement of a material fact or omit to state any
      material fact necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading, or if it shall
      be necessary to amend or supplement the Final Prospectus to comply with
      the Act or the Exchange Act or the respective rules thereunder, the
      Company promptly will prepare and file with the Commission, subject to the
      first sentence of paragraph (a) of this Section 5, an amendment or
      supplement which will correct such statement or omission or an amendment
      which will effect such compliance and will use its best efforts to cause
      any required post-effective amendment to the Registration Statement
      containing such amendment to be made effective as soon as possible.

            (c)   The Company will furnish to the Underwriter and counsel for
      the Underwriter, without charge, executed copies of the Registration
      Statement (including exhibits thereto) and each amendment thereto which
      shall become effective on or prior to the Closing Date and, so long as
      delivery of a prospectus by the Underwriter or dealers


                                        7



      may be required by the Act, as many copies of the Final Prospectus and any
      amendments thereof and supplements thereto as the Underwriter may
      reasonably request. The Company will pay the expenses of printing all
      documents relating to the initial offering, provided that any additional
      expenses incurred in connection with the requirement of delivery of a
      market-making prospectus, if applicable, will be borne by the Underwriter.

            (d)   The Company will furnish such information as may be required
      and otherwise cooperate in qualifying the Offered Certificates for sale
      under the laws of such jurisdictions as the Underwriter may reasonably
      designate and to maintain such qualifications in effect so long as
      required for the distribution of the Offered Certificates; provided,
      however, that the Company shall not be required to qualify to do business
      in any jurisdiction where it is not now so qualified or to take any action
      which would subject it to general or unlimited service of process in any
      jurisdiction where it is not now so subject.

      SECTION 6.     Conditions to the Obligations of the Underwriter. The
obligations of the Underwriter to purchase the Offered Certificates shall be
subject to the accuracy of the representations and warranties on the part of the
Company contained herein as of the date hereof, as of the date of the
effectiveness of any amendment to the Registration Statement filed prior to the
Closing Date (including the filing of any document incorporated by reference
therein) and as of the Closing Date, to the accuracy of the statements of the
Company made in any certificates delivered pursuant to the provisions hereof, to
the performance by the Company of its obligations hereunder and to the following
additional conditions:

            (a)   The Underwriter shall have received from
      PricewaterhouseCoopers LLP (i) a letter, dated the date hereof, confirming
      that they are independent public accountants within the meaning of the Act
      and the rules and regulations of the Commission promulgated thereunder and
      otherwise in form and substance reasonably satisfactory to the Underwriter
      and counsel to the Underwriter and (ii) if requested by the Underwriter, a
      letter dated the Closing Date, updating the letter referred to in clause
      (i) above, in form and substance reasonably satisfactory to the
      Underwriter and counsel for the Underwriter.

            (b)   All actions required to be taken and all filings required to
      be made by the Company under the Act prior to the sale of the Offered
      Certificates shall have been duly taken and made. At and prior to the
      Closing Date, no stop order suspending the effectiveness of the
      Registration Statement shall have been issued and no proceedings for that
      purpose shall have been instituted, or to the knowledge of the Company or
      the Underwriter, shall have been contemplated by the Commission.

            (c)   Subsequent to the execution and delivery of this Agreement,
      there shall not have occurred (i) any change, or any development involving
      a prospective change, in or affecting particularly the business or
      properties of the Company, any Servicer or the Master Servicer which, in
      the reasonable judgment of the Underwriter, materially impairs the
      investment quality of the Offered Certificates; (ii) any downgrading in
      the ratings of the securities of any Servicer or the Master Servicer by
      any "nationally recognized statistical rating organization" (as such term
      is defined for purposes of Rule 436(g) under the Act), or any public
      announcement that any such organization has under surveillance


                                        8



      or review its ratings of any securities of any Servicer or the Master
      Servicer (other than an announcement with positive implications of a
      possible upgrading, and no implication of a possible downgrading, of such
      rating); (iii) any suspension or limitation of trading in securities
      generally on the New York Stock Exchange, or any setting of minimum prices
      for trading on such exchange; (iv) any banking moratorium declared by
      federal, North Carolina or New York authorities; or (v) any outbreak or
      escalation of major hostilities in which the United States is involved,
      any declaration of war by Congress or any other substantial national or
      international calamity or emergency if, in the reasonable judgment of the
      Underwriter, the effects of any such outbreak, escalation, declaration,
      calamity or emergency makes it impractical or inadvisable to proceed with
      completion of the sale of and payment for the Offered Certificates.

            (d)   The Underwriter shall have received a certificate dated the
      Closing Date of an executive officer of the Company in which such officer
      shall state that, to the best of such officer's knowledge after reasonable
      inspection, (i) the representations and warranties of the Company
      contained in the Basic Documents are true and correct with the same force
      and effect as if made on the Closing Date and (ii) the Company has
      complied with all agreements and satisfied all conditions on its part to
      be performed or satisfied hereunder at or prior to the Closing Date.

            (e)   The Underwriter shall have received an opinion of reasonably

            (g)   The Underwriter shall have received copies of any opinions of
      counsel for the Company that the Company is required to deliver to any
      Rating Agency. Any such opinions shall be dated the Closing Date and

      to the Underwriter.

            (h)   The Underwriter shall have received from Hunton & Williams
      LLP, special counsel to the Underwriter, a letter addressed to the
      Underwriter dated the Closing Date with respect to the Final Prospectus,
      substantially to the effect that no facts have come to such counsel's
      attention in the course of its review of the Final Prospectus which causes
      it to believe that the Final Prospectus, as of the date of the Prospectus
      Supplement or the Closing Date, contained any untrue statement of a
      material fact or omitted to state 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; it being
      understood that such counsel need not express any view as to any
      information incorporated by reference in the Final Prospectus or as to the
      adequacy or accuracy of the financial, numerical, statistical or
      quantitative information included in the Final Prospectus.


                                        9



            (i)   On or before the Closing Date, the Underwriter shall have

      Servicing Agreement will conform in all material respects to the
      descriptions thereof contained in the Final Prospectus.

            (k)   The Underwriter shall not have discovered and disclosed to the
      Company on or prior to the Closing Date that the Registration Statement or
      the Final Prospectus or any amendment or supplement thereto contains an
      untrue statement of a fact or omits to state a fact which, in the opinion
      of counsel to the Underwriter, is material and is required to be stated
      therein or is necessary to make the statements therein not misleading.

            (l)   All corporate proceedings and other legal matters relating to
      the authorization, form and validity of this Agreement, the Pooling and
      Servicing Agreement, the Mortgage Loan Purchase Agreement, the
      Certificates, the Registration Statement and the Final Prospectus, and all
      other legal matters relating to this Agreement and the transactions
      contemplated hereby, shall be reasonably satisfactory in all respects to
      counsel for the Underwriter, and the Company shall have furnished to such
      counsel all documents and information that they may reasonably request to
      enable them to pass upon such matters.

            (m)   The Underwriter shall have received a certificate (upon which

      of the mortgage loans; and (iii) the Custodian Disclosure is true and
      correct in all material respects and nothing has come to his or her
      attention that that would lead such officer to believe that the Custodian
      Disclosure contains any untrue statement of material fact or omits to
      state a material fact necessary to make the statements therein not
      misleading.

            (n)   The Underwriter shall have received a certificate (upon which
      Hunton & Williams LLP shall be entitled to rely in rendering its opinions

      her attention


                                       10



      that that would lead such officer to believe that the Trustee Disclosure
      contains any untrue statement of material fact or omits to state a
      material fact necessary to make the statements therein not misleading.

            (o)   The Underwriter shall have received a certificate (upon which
      Hunton & Williams LLP shall be entitled to rely in rendering its opinions
      and letters under the Basic Documents) dated the Closing Date of an
      officer of SunTrust Mortgage, Inc., National City Mortgage Co. and Wells
      Fargo Bank, N.A. (each a "Significant Originator" and together the
      "Significant Originators") in which such officer shall state that, to the
      best of such officer's knowledge after reasonable investigation: (i) the
      Significant Originator is not an affiliate of any other entity listed as a
      transaction party in the Prospectus Supplement; (ii) the information in
      the Prospectus Supplement related to the Significant Originator (the
      "Originator Disclosure") includes the Significant Originator's correct
      name, form of organization and length of time originating mortgage loans;
      (iii) the description of the Significant Originator's origination program
      includes (a) experience in originating mortgage loans, (b) size and

      performance of the pool assets or the Offered Certificates; and (v) the
      Originator Disclosure is true and correct in all material respects and
      nothing has come to his or her attention that that would lead such officer
      to believe that the Originator Disclosure contains any untrue statement of
      material fact or omits to state a material fact necessary to make the
      statements therein not misleading.

            (p)   The Underwriter shall have received a certificate (upon which
      Hunton & Williams LLP shall be entitled to rely in rendering its opinions
      and letters under the Basic Documents) dated the Closing Date of an
      officer of SunTrust Mortgage, Inc., National City Mortgage Co. and Wells
      Fargo Bank, N.A. (each a "Significant Servicer" and together the
      "Significant Servicers") and the Master Servicer in which such officer
      shall state that, to the best of such officer's knowledge after reasonable

      no additional information with respect to the Significant Servicer's or

      performing work-outs or foreclosures, or any other material aspect of

      would lead such officer to believe that the Servicer Disclosure contains
      any untrue statement of material fact or omits to state a material fact
      necessary to make the statements therein not misleading.

      The Company will provide or cause to be provided to the Underwriter such
conformed copies of such opinions, certificates, letters and documents as the
Underwriter may reasonably request.

      All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriter.

      If any condition specified in this Section 6 shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Underwriter by notice to the Company at any time at or prior to the Closing
Date, and such termination shall be without liability of any party to any other
party except as provided in Section 7.

      SECTION 7.     Reimbursement of the Underwriter's Expenses. If the sale of
the Offered Certificates provided for herein is not consummated because any
condition to the obligations of the Underwriter set forth in Section 6 hereof is
not satisfied or because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or comply with any provision hereof
other than by reason of a default by the Underwriter, the Company will reimburse
the Underwriter upon demand for all out-of-pocket expenses (including reasonable
fees and disbursements of counsel) that shall have been reasonably incurred by
the Underwriter in connection with the proposed purchase and sale of the Offered
Certificates.

      SECTION 8.     Indemnification and Contribution. The Company agrees to
indemnify and hold harmless the Underwriter and any 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
or either of them 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 (1) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement for
the registration of the Offered Certificates as originally filed or in any
amendment thereof, or in the Basic Prospectus or the Final Prospectus or the
Disclosure Package, or in any amendment thereof or supplement thereto, or arise
out of or are based upon


                                       12



the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, (2) any untrue
statement or alleged untrue statement of a material fact contained in any Issuer
Free Writing Prospectus or any Issuer Information (as defined in Section 12(b))
contained in any Free Writing Prospectus prepared by or on behalf of the
Underwriter or in any Free Writing Prospectus which is required to be filed
pursuant to Section 12(e) or Section 12(g), or the omission or alleged omission
to state a material fact required to make the statements therein, in light of
the circumstances under which they were made, not misleading, which was not
corrected by information subsequently supplied by the Depositor to the
Underwriter at any time prior to the time of sale, and agrees to reimburse the
Underwriter and any such controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action and (3) any static pool
information prepared by the Company and incorporated by reference into a
prospectus or Free Writing Prospectus in connection with the offering of the
Offered Certificates, to the extent not included above; provided, however, that
(i) the Company 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 (A)
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of the Underwriter specifically for use in
connection with the preparation thereof or (B) in any Current Report or any
amendment or supplement thereof, and (ii) such indemnity with respect to the
Prospectus shall not inure to the benefit of the Underwriter (or any person
controlling the Underwriter) from whom the person asserting any such loss,
claim, damage or liability purchased the Offered Certificates which are the
subject thereof if such person did not receive a copy of the Final Prospectus
(or the Final Prospectus as amended or supplemented) excluding documents
incorporated therein by reference at or prior to the confirmation of the sale of
such Offered Certificates to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact
contained in the Basic Prospectus was corrected in the Final Prospectus (or the
Final Prospectus as amended or supplemented). This indemnity agreement will be
in addition to any liability which the Company may otherwise have.

            (a)   The Underwriter agrees to indemnify and hold harmless the
      Company, each of its directors, each of its officers who signs the
      Registration Statement and each person who controls the Company within the
      meaning of either the Act or the Exchange Act, to the same extent as the
      foregoing indemnity from the Company to the Underwriter, but only with
      reference to (A) written information relating to the Underwriter furnished
      to the Company by or on behalf of the Underwriter specifically for use in
      the preparation of the documents referred to in the foregoing indemnity,
      or (B) any Free Writing Prospectus (as defined in Section 12(a)) prepared
      by or on behalf of the Underwriter, any Computational Materials,
      Collateral Term Sheets or ABS Term Sheets furnished to the Company by the
      Underwriter pursuant to Section 12 and incorporated by reference in the
      Registration Statement or the Final Prospectus, except that no such
      indemnity shall be available for any losses, claims, damages, liabilities
      or actions in respect thereof resulting from any error in any Issuer
      Information (as defined in Section 12(b)) (an "Issuer Error") furnished by
      the Company to the Underwriter in writing or by electronic transmission
      that was used in the preparation of any Free Writing Prospectus,
      Computational Materials, Collateral Term Sheets or ABS Term Sheets, other
      than an Issuer Error as to which, prior to the time of the sale of the
      Offered Certificates to the person asserting a


                                       13



      claim, the Company notified the Underwriter in writing of the Issuer Error
      or provided in written or electronic form information superseding or
      correcting such Issuer Error (in any such case, a "Corrected Issuer
      Error"), and the Underwriter failed to notify such person thereof or to
      deliver such person corrected Free Writing Prospectus, Computational
      Materials, Collateral Term Sheets and/or ABS Term Sheets, as applicable.
      This indemnity agreement will be in addition to any liability which the
      Underwriter may otherwise have. The Company acknowledges that the
      statements set forth in the Prospectus Supplement in the first sentence of
      the last paragraph on the cover page, in the first sentence under the
      subheading "Risk Factors--Limited Liquidity" and in the second, third and
      fifth paragraphs under the heading "Method of Distribution" constitute the
      only information furnished in writing by or on behalf of the Underwriter
      for inclusion in the documents referred to in the foregoing indemnity
      (other than any Free Writing Prospectus, Computational Materials,
      Collateral Term Sheets or ABS Term Sheets furnished to the Company by the
      Underwriter).

            (b)   Promptly after receipt by an indemnified party under this
      Section 8 of notice of the commencement of any action, such indemnified
      party will, if a claim in respect thereof is to be made against the
      indemnifying party under this Section 8, notify the indemnifying party in
      writing of the commencement thereof; but the omission so to notify the
      indemnifying party will not relieve it from any liability which it may
      have to any indemnified party otherwise than under this Section 8. In case
      any such action is brought against any indemnified party, and it notifies
      the indemnifying party of the commencement thereof, the indemnifying party
      will 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 reasonably satisfactory to such indemnified
      party; provided, however, that if the defendants in any such action
      include both the indemnified party and the indemnifying party and the
      indemnified party shall have reasonably concluded that there may be legal
      defenses available to it and/or other indemnified parties which are
      different from or additional to those available to the indemnifying party,
      the indemnified party or parties shall have the right to select separate
      counsel to assert such legal defenses and to otherwise participate in the
      defense of such action on behalf of such indemnified party or parties.
      Upon receipt of notice from the indemnifying party to such indemnified
      party of its election so to assume the defense of such action and approval
      by the indemnified party of counsel, the indemnifying party will not be
      liable to such indemnified party under this Section 8 for any legal or
      other expenses subsequently incurred by such indemnified party in
      connection with the defense thereof unless (i) the indemnified party shall
      have employed separate counsel in connection with the assertion of legal
      defenses in accordance with the proviso to the next preceding sentence (it
      being understood, however, that the indemnifying party shall not be liable
      for the expenses of more than one separate counsel, approved by the
      Underwriter in the case of subparagraph (a), representing the indemnified
      parties under subparagraph (a) who are parties to such action), (ii) the
      indemnifying party shall not have employed counsel reasonably satisfactory
      to the indemnified party to represent the indemnified party within a
      reasonable time after notice of commencement of the action or (iii) the
      indemnifying party has authorized the employment of counsel for the
      indemnified party at the expense


                                       14



      of the indemnifying party; and except that if clause (i) or (iii) is
      applicable, such liability shall be only in respect of the counsel
      referred to in such clause (i) or (iii).

            (c)   To provide for just and equitable contribution in
      circumstances in which the indemnification provided for in paragraphs (a)
      or (b) of this Section 8 is due in accordance with its terms but is for
      any reason held by a court to be unavailable from the Company or the
      Underwriter on the grounds of policy or otherwise, the Company or the
      Underwriter shall contribute to the aggregate losses, claims, damages and
      liabilities (including legal or other expenses reasonably incurred in
      connection with investigating or defending same) to which the Company or
      the Underwriter may be subject, as follows:

                  (i)     in the case of any losses, claims, damages and
            liabilities (or actions in respect thereof) which do not arise out
            of or are not based upon any untrue statement or omission of a
            material fact in any Free Writing Prospectus, in such proportion as
            is appropriate to reflect the relative benefit received by the
            Company or the Underwriter; and

                  (ii)    in the case of any losses, claims, damages and
            liabilities (or actions in respect thereof) which arise out of or
            are based upon any untrue statement or omission of a material fact
            in any Free Writing Prospectus, in such proportion as is appropriate
            to reflect the relative fault of the Company and the Underwriter in
            connection with the statements or omissions which resulted in such
            losses, claims, damages or liabilities (or actions in respect
            thereof) as well as any other relevant equitable considerations. The
            relative fault 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 in
            such Free Writing Prospectus results from information prepared by
            the Company or the Underwriter and the parties' relative intent,
            knowledge, access to information and opportunity to correct or
            prevent such statement or omission.

Notwithstanding anything to the contrary in this paragraph (c), 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. For purposes of this Section 8, each person who
controls the Underwriter within the meaning of either the Act or the Exchange
Act shall have the same rights to contribution as the Underwriter and each
person who controls the Company within the meaning of either the Act or the
Exchange Act, and each officer of the Company who shall have signed the
Registration Statement and each director of the Company shall have the same
rights to contribution as the Company, subject in each case to the preceding
sentence of this paragraph (c). Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this paragraph (c), notify such
party or parties from whom contribution may be sought, but the omission to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this paragraph (c).

      SECTION 9.     [Reserved.]


                                       15



      SECTION 10.    Representations and Indemnities to Survive.

      The respective agreements, representations, warranties, indemnities and
other statements of the Company and its respective officers and of the
Underwriter set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation made by or on behalf of the
Underwriter or the Company or any of the officers, directors or controlling
persons referred to in Section 8 hereof, and will survive delivery of and
payment for the Offered Certificates. The provisions of Sections 7 and 8 hereof
and this Section 10 shall survive the termination or cancellation of this
Agreement.

      SECTION 11.    Effectiveness of Agreement and Termination. This Agreement
shall become effective upon the execution and delivery hereof by the parties
hereto.

      This Agreement shall be subject to termination in the absolute discretion
of the Underwriter, by notice given to the Company prior to delivery of and
payment for the Offered Certificates, if prior to such time (i) trading in
securities generally on the New York Stock Exchange shall have been suspended or
limited or minimum prices shall have been established on such Exchange, (ii) a
banking moratorium shall have been declared by federal authorities or (iii)
there shall have occurred any outbreak or material 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
