Ladies and Gentlemen:

 1.      Introductory.  Structured Asset Securities Corporation, a Delaware corporation (the "Depositor"), proposes to form one or more trusts (the "Trusts"), which will issue, from time to time, securities entitled Mortgage-Backed Notes (the "Notes") in one or more series (each a "Series").  Each Trust may issue one or more classes of Notes (each, a "Class") pursuant to an Indenture to be dated as of the respective cut-off date (each, a "Cut-off Date") as supplemented by one or more supplements to such Indenture (such Indenture, as supplemented, the "Indenture") between the related Trust and the indenture trustee named therein (the "Indenture Trustee").  Simultaneously with the issuance of the Notes, the Trust may issue Residual Interest Certificates (the "Certificates"), each representing a fractional undivided ownership interest in the related Trust, pursuant to a separate Trust Agreement (each, a "Trust Agreement") to be dated as of the respective Cut-off Date among the Depositor, the administrator named therein (the "Administrator") and the owner trustee named therein (the "Owner Trustee").  The Trusts will issue Notes on terms specified in the applicable Prospectus (as hereinafter defined).  The Primary Assets (the "Primary Assets") of each Trust (the "Trust Fund") will consist of (a) fixed- or adjustable-rate, fully amortizing, conventional, first lien residential mortgage loans (the "Mortgage Loans"), (b) manufactured housing conditional sales contracts and installment loan agreements with respect to manufactured homes (the "Manufactured Home Loans") secured by new or used manufactured homes, (c) Private Mortgage-Backed Securities which may consist of mortgage pass-through or participation certificates, evidencing an undivided interest in a pool of mortgage loans, or collateralized mortgage obligations secured by mortgage loans, (d) mortgage loans (the "FHA Loans") insured by the Federal Housing Administration (the "FHA"), mortgage loans ("VA Loans") partially guaranteed by the Veterans Administration (the "VA") (collectively, the "FHA/VA Mortgage Loans") and certain related property to be conveyed to the Trust by the Depositor, (e) participation certificates representing undivided ownership interests in a pool of mortgage loans as described above, or (f) pass-through certificates guaranteed by the Government National Mortgage Association, the Federal Home Loan Mortgage Corporation or the Federal National Mortgage Association.

The Primary Assets of each Trust will be transferred to the related Trust pursuant to a Sale and Servicing Agreement (the "Sale and Servicing Agreement"), with respect to each Series among the Depositor, the related Trust, the related Indenture Trustee and a master servicer to be identified in the prospectus supplement for each such Series (the "Master Servicer").

The Notes are more fully described in the Registration Statement (as defined herein), which the Depositor has furnished to you.  Each Series of Notes and any Classes of Notes within such Series may vary as to, among other things, number and types of Classes, principal or notional amount, interest rate, the percentage interest, if any, evidenced by each Class in the payments of principal of and interest on, or with respect to, the Primary Assets held by the related Trust, priority of payment among Classes, credit enhancement with respect to the Primary Assets held by the related Trust Fund, the Classes of such Series subject to this Agreement, and any other terms contemplated by the Indenture or the Sale and Servicing Agreement with respect to the Notes of such Series.

If and to the extent specified in the related Sale and Servicing Agreement, in addition to the Primary Assets conveyed to the Trust on the Closing Date (such Primary Assets so conveyed to the Trust at such time, the "Initial Primary Assets"), the Depositor shall be obligated to convey to the Trust, from time to time during the period commencing after the Closing Date and ending at the expiration of the period specified in such Sale and Servicing Agreement (each such period a "Pre-Funding Period") (the date of any such conveyance, a "Subsequent Transfer Date"), additional Primary Assets (any such additional Primary Assets so conveyed to the Trust through the Pre-Funding Period, the "Subsequent Primary Assets").

Each offering of the Notes to which this Agreement applies will be made pursuant to the Registration Statement through you or through an underwriting syndicate managed by you.  Whenever the Depositor determines to form a Trust and to make such an offering of Notes, it will enter into an appropriate agreement (the "Terms Agreement"), a form of which is attached hereto as Exhibit A, providing for the sale of certain classes of such Notes to, and the purchase and offering thereof by, you and such other underwriters, if any, selected by you as have authorized you to enter into such Terms Agreement on their behalf (the "Underwriters," which term shall include you, whether acting alone in the sale of such Notes, in which case any reference herein to you as the Representative of the Underwriters shall be deemed to refer to you in your individual capacity as Underwriter of the Notes, or as a member of an underwriting syndicate).  Such Terms Agreement shall specify the undivided interest, principal or notional amount of each Class of the Notes to be issued, the Classes of Notes subject to this Agreement, the price at which such Classes of Notes are to be purchased by the Underwriters from the Depositor and the initial public offering price or the method by which the price at which such Notes are to be sold will be determined.

Each such offering of the Notes will be governed by this Agreement, as supplemented by the applicable Terms Agreement, and this Agreement and such Terms Agreement shall inure to the benefit of and be binding upon each Underwriter participating in the offering of such Notes.  Capitalized terms not otherwise defined herein are defined in the Sale and Servicing Agreement.

 5.      Covenants of the Depositor.  The Depositor covenants, and agrees with you and the several Underwriters participating in the applicable offering of the Notes that:

(a)     immediately following the execution of each Terms Agreement, the Depositor will prepare a Prospectus Supplement setting forth the amount of Notes covered thereby and the terms thereof not otherwise specified in the Prospectus, the price at which such Notes are to be purchased by the Underwriters from the Depositor, either the initial public- offering price or the method by which the price at which such Notes are to be sold will be determined, the selling concessions and reallowances, if any, and such other information as you and the Depositor deem appropriate in connection with the offering of such Notes, but the Depositor will not file any amendments to the Registration Statement as in effect with respect to the Notes, or any amendments or supplements to the Prospectus, unless it shall first have delivered copies of such amendments or supplements to the Representative and the Representative shall not have reasonably objected thereto promptly after receipt thereof; the Depositor will immediately advise you or your counsel (i) when notice is received from the Commission that any post-effective amendment to the Registration Statement has become or will become effective and (ii) of any order or communication suspending or preventing, or threatening to suspend or prevent, the offer and sale of the Notes or of any proceedings or examinations that may lead to such an order or communication, whether by or of the Commission or any authority administering any state securities or Blue Sky law, as soon as the Depositor is advised thereof, and the Depositor will use its best efforts to prevent the issuance of any such order or communication and if such order is issued, the Depositor will obtain its lifting as soon as possible;

(c)     if, at any time when a Prospectus relating to the Notes is required to be delivered under the Act, 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 any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Prospectus to comply with the Act or the Rules and Regulations thereunder, the Depositor will promptly prepare and file with the Commission an amendment or supplement that will correct such statement or omission or an amendment that will effect such compliance; provided, however, that the Depositor will not be required to file any such amendment or supplement with respect to any Computational Materials, Structural Term Sheets or Collateral Term Sheets incorporated by reference in the Prospectus other than any amendments or supplements of such Computational materials or Structural Term Sheets that are furnished to the Depositor by the Underwriters pursuant to Section 8(e) hereof or any amendments or supplements of such Collateral Term Sheets that are furnished to the Depositor by the Underwriters pursuant to section 9(d) hereof which are required to be filed in accordance therewith;

(g)     the Depositor will cause the Indenture Trustee while the Notes of a Series are outstanding to;

(i)

furnish to you, and upon your request to each of the other Underwriters, within 90 days after the close of each fiscal year, appropriate annual financial statements of the related Trust, in such form as to disclose its financial condition at the end of, and the results of its operations for, such fiscal year;

In addition, such counsel has participated in conferences with officers and other representatives of the Depositor, your counsel, representatives of the independent accountants for the Trust and you at which the contents of the Registration Statement and the Prospectus were discussed and, although such counsel is not passing upon and does not assume responsibility for the factual accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus (except as stated in paragraph (xi) above) and has made no independent check or verification thereof for the purpose of rendering its opinion, on the basis of the foregoing (relying as to materiality to a large extent upon the certificates of officers and other representatives of the Depositor), nothing has come to such counsel's attention that leads it to believe that either the Registration Statement or the Prospectus at the time such documents were delivered to you contained, or at the date hereof contains, an untrue statement of a material fact or at the time such documents were delivered to you omitted, or at the date hereof omits, 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, except that such counsel need express no view with respect to the financial statements, schedules and other financial and statistical data included in or incorporated by reference in or omitted from the Registration Statement or the Prospectus.

With respect to the opinions expressed in paragraph (viii) above, such counsel may take such exceptions as are deemed necessary and appropriate by such counsel to deliver such opinion.

(f)     if applicable, you shall have received an opinion of counsel to the Owner Trustee and the Indenture Trustee dated the applicable Closing Date and in the form agreed to on or prior to the date of the applicable Terms Agreement;

(g)     if applicable, you shall have received an opinion of counsel to any issuer of any certificate insurance policy, dated the applicable Closing Date, and in the form agreed to on or prior to the date of the applicable Terms Agreement;

(h)     if applicable, you shall have received the opinion of counsel to the Master Servicer, dated as of the applicable Closing Date, in form and substance satisfactory to your counsel, to the effect that:

(i)

the Master Servicer has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation and is duly qualified to do business, and is in good standing, as a foreign corporation under the laws of each jurisdiction in which the performance of its duties under the applicable agreement would require such qualification;

(ii)

the execution and delivery by the Master Servicer of the applicable agreement is within the corporate power of the Master Servicer and has been duly authorized by all necessary corporate action on the part of the Master Servicer; and neither the execution and delivery of such instrument, nor the consummation of the transactions provided for therein, nor compliance with the provisions thereof, will conflict with or constitute a breach of, or default under, any contract, indenture, mortgage, loan agreement, note, lease, deed of trust, or other instrument to which the Master Servicer is a party or by which it may be bound, nor will such action result in any violation of the provisions of the charter or bylaws of the Master Servicer or any law, administra­tive regulation or administrative or court, decree;

(iii)

the applicable agreement has been duly and validly authorized, executed and delivered by the Master Servicer and assuming due authorization, execution and delivery by the other parties thereto, constitutes the valid and binding obligation of the Master Servicer, enforceable in accordance with its terms, subject, as the enforcement of remedies, to (A) applicable bankruptcy, insolvency, reorganization, moratorium or other laws relating to creditors' rights generally as from time to time in effect, (B) to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (C) if applicable, with respect to the qualification that certain remedial provisions of the Trust Agreement, Indenture or Sale and Servicing Agreement, if any, may be unenforceable in whole or in part under the Uniform Commercial Code as presently in effect in the State of New York, but the inclusion of such provisions does not render the other provisions of the Indenture invalid and the Indenture contains adequate remedial provisions for the practical realization of the benefits of the security provided thereby;

(i)     if  applicable, you shall have received an opinion of counsel to each Servicer, dated the applicable Closing Date, and in the form agreed to on or prior to the date of the applicable Terms Agreement;

(j)     you shall have received from McKee Nelson LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the Registration Statement, the Prospectus and other related matters as the Underwriters may require, and the Depositor shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters; and

(k)     you shall have received a certificate or certificates signed by such of the principal executive, financial and accounting officers of the Depositor as you may request, dated the applicable Closing Date, in which such officers, to the best of their knowledge after reasonable investigation, shall state that (i) the representations and warranties of the Depositor in this Agreement are true and correct; (ii) the Depositor has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to the Closing Date; (iii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are contemplated; (iv) subsequent to the respective dates as of which information is given in the Prospectus, and except as set forth or contemplated in the Prospectus, there has not been any material adverse change in the general affairs, capitalization, financial condition or results of operations of the Depositor; and (v) except as otherwise stated in the Prospectus, there are no material actions, suits or proceedings pending before any court or governmental agency, authority or body or, to their knowledge, threatened, which could have a material effect upon the Depositor or upon the transactions contemplated by this Agreement.  

The Depositor will furnish you with such copies of such opinions, certificates, letters and documents as you reasonably request.

 7.      Indemnification.

(a)     The Depositor will indemnify and hold harmless each underwriter and each person, if any, who controls any underwriter within the meaning of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission (in the case of any Computational Materials or ABS Term Sheets (as defined in Section 9 below) in respect of which the Depositor agrees to indemnify each Underwriter, as set orth below, when such are read in conjunction with the related Prospectus and Prospectus Supplement) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter and each such controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that (i) the Depositor 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 in or omission or alleged omission made in any such documents (A) in reliance upon and in conformity with written information furnished to the Depositor by an Underwriter specifically for use therein or (B) in any Current Report or any amendment or supplement thereof, except to the extent that any untrue statement or alleged untrue statement therein or omission therefrom results (or is alleged to have resulted) directly from an error (a "Mortgage Pool Error") in the information concerning the characteristics of the Mortgage Loans furnished by the Depositor to any Underwriter in writing or by electronic transmission that was used in the preparation of any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) included in such Current Report (or amendment or supplement thereof), (ii) such indemnity with respect to any Prospectus or any Corrected Statement (as defined below) in any Prospectus (or supplement thereto) shall not inure to the benefit of any Underwriter (or any person controlling any Underwriter) from whom the person asserting any loss, claim, damage or liability purchased the Notes of the related Series that are the subject thereof if such person did not receive a copy of the related Prospectus or a supplement to such Prospectus, as the case may be, at or prior to the confirmation of the sale of such Notes and the untrue statement or omission of a material fact contained in such Prospectus (or supplement thereto) was corrected (a "Corrected Statement") in such Prospectus or in such other supplement and such Prospectus or such supplement was furnished by the Depositor to such Underwriter prior to the delivery of such confirmation, and (iii) such indemnity with respect to any Mortgage Pool Error shall not inure to the benefit of any Underwriter (or any person controlling any Underwriter) from whom the person asserting any loss, claim, damage or liability received any Computational Materials or ABS Term Sheets (or any written or electronic materials on which the Computational Materials are based) that were prepared on the basis of such Mortgage Pool Error, if, prior to the time of confirmation of the sale of the applicable Notes to such person, the Depositor notified such Underwriter in writing of the Mortgage Pool Error or provided in written or electronic form information superseding or correcting such Mortgage Pool Error (in any such case, a "Corrected Mortgage Pool Error"), and such Underwriter failed to notify such person thereof or to deliver to such person corrected Computational Materials (or underlying written or electronic materials) or ABS Term Sheets.  This indemnity agreement will be in addition to any liability which the Depositor may otherwise have.  This indemnity agreement will be in addition to any liability which the Depositor may otherwise have.

(b)     Each Underwriter, severally, and not jointly, will indemnify and hold harmless the Depositor, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Depositor within the meaning of the Act against any losses, claims, damages or liabilities to which the Depositor or any such director, officer or controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, 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 (A) written information furnished to the Depositor by such Underwriter specifically for use in the preparation of the documents referred to in the foregoing indemnity provided by the Depositor to each Underwriter with respect to the related Series, or (B) any Computational Materials or ABS Term sheets (or amendments or supplements thereof) delivered to prospective investors by such Underwriter and furnished to the Depositor by such Underwriter pursuant to Section 8 and incorporated by reference in such Registration Statement, the related Prospectus or any amendment or supplement thereof (except that no such indemnity shall be available for any losses, claims, damages or liabilities, or actions in respect thereof, resulting from any Mortgage Pool Error, other than a Corrected Mortgage Pool Error).  The Depositor acknowledges that the statements set forth in the last paragraph appearing on the cover page of the related Prospectus as such statements relate to such Notes and the first paragraph (including any table listed below such paragraph) and the third sentence of the second paragraph under the heading "Underwriting" in such Prospectus Supplement as such statements relate to such Notes constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the related Prospectus (other than any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) delivered to prospective investors and furnished to the Depositor by any particular Underwriter), and the Underwriters confirm that such statements are correct.  Any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) furnished to the Depositor by a particular Underwriter shall relate exclusively to and be the several responsibility of such Underwriter and no other Underwriter.  Subject to the foregoing provisions set forth in this paragraph (b), each Underwriter, severally, but not jointly, agrees to reimburse any legal or other expenses reasonably incurred by the Depositor or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action.  This indemnity agreement will be in addition to any liability that such Underwriter may otherwise have.

(c)     Promptly after receipt by an indemnified party under this Section 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, notify the indemnifying party 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 in this Section.  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, jointly with any other indemnifying party similarly notified, elect to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after 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 for any legal or other expenses subsequently incurred by such indemnified party in connection with defense thereof other than reasonable costs of investigation.

(d)     If recovery is not available under the foregoing indemnification provisions of this Section for any reason other than as specified therein, the parties entitled to indemnification by the terms thereof shall be entitled to contribution to liabilities and expenses as set forth in Section 13 of this Agreement, except to the extent that contribution is not permitted under Section 11(f) of the Act.  In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative benefits received by each party from the offering of the Notes subject to this Agreement (taking into account the portion of the proceeds of the offering realized by each), the parties' relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any other equitable considerations appropriate under the circumstances.  The Depositor and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose).  No Underwriter or person controlling such Underwriter shall be obligated to make contribution hereunder which in the aggregate exceeds the total public offering price of the Notes purchased by such Underwriter under this Agreement, less the aggregate amount of any damages which such Underwriter and its controlling persons have otherwise been required to pay in respect of the same claim or any substantially similar claim.  The Underwriters'­obligations to contribute are several in proportion to their respective underwriting obligations and not joint.

 8.      Computational Materials and Structural Term Sheets.

(a)     Not later than 2:00 p.m., New York time, on the business day before the date on which the Current Report relating to the Notes of a Series is required to be filed by the Depositor with the Commission pursuant to Section 5(b) hereof, the Underwriters shall deliver to the Depositor five complete copies of all materials provided by the Underwriters to prospective investors in such Notes which constitute (i) "Computational Materials" within the meaning of the no action letter dated May 20, 1994 issued by the Division of Corporation Finance of the Commission to Kidder, Peabody Acceptance Corporation 1, Kidder, Peabody & Co. Incorporated, and Kidder Structured Asset Corporation and the no action letter dated May 27, 1994 issued by the Division of Corporation Finance of the Commission to the Public Securities Association (together, the "Kidder Letters"), the filing of which material is a condition of the relief granted in such letter (such materials being the "Computational Materials"), and (ii) "Structural Term Sheets" within the meaning of the no-action letter dated February 17, 1995 issued by the Division of Corporation Finance of the Commission to the Public Securities Association (the "PSA Letter"), the filing of which material is a condition of the relief granted in such letter (such materials being the "Structural Term Sheets").  Each delivery of Computational Materials and Structural Term Sheets to the Depositor pursuant to this paragraph (a) shall be effected by delivering four copies of such materials to counsel for the Depositor on behalf of the Depositor and one copy of such materials to the Depositor.

(b)     Each Underwriter represents and warrants to and agrees with the Depositor, as of the date of the related Terms Agreement and as of the Closing Date, that:

(i)

the Computational Materials furnished to the Depositor by such Underwriter pursuant to Section 8(a) constitute (either in original, aggregated or consolidated form) all of the materials furnished to prospective investors by such Underwriter prior to the time of delivery thereof to the Depositor that are required to be filed with the Commission with respect to the related Notes in accordance with the Kidder Letters, and such Computational Materials comply with the requirements of the Kidder Letters;

(ii)

the Structural Term Sheets furnished to the Depositor by such Underwriter pursuant to Section 8(a) constitute all of the materials furnished to prospective investors by such Underwriter prior to the time of delivery thereof to the Depositor that are required to be filed with the Commission as "Structural Term Sheets" with respect to the related Certificates in accordance with the PSA Letter, and such Structural Term Sheets comply with the requirements of the PSA Letter;

(iii)

on the date any such Computational Materials or Structural Term Sheets with respect to such Notes (or any written or electronic materials furnished to prospective investors on which the Computational Materials are based) were last furnished to each prospective investor by such Underwriter and on the date of delivery thereof to the Depositor pursuant to Section 8(a) and on the related Closing Date, such Computational Materials (or such other materials) or Structural Term Sheets did not and will not include any untrue statement of a material fact or, when read in conjunction with the Prospectus and Prospectus Supplement, omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

(iv)

all Computational Materials (or underlying materials distributed to prospective investors on which the Computational Materials were based) delivered to prospective investors by such Underwriter and all Structural Term Sheets delivered to prospective investors by such Underwriter contained and will contain a legend, prominently displayed on the first page thereof, to the effect that the Depositor has not prepared, reviewed or participated in the preparation of such materials and is not responsible for the accuracy thereof, or otherwise in form and substance satisfactory to the Depositor.

Notwithstanding the foregoing, each Underwriter makes no representation or warranty as to whether any Computational Materials or Structural Term Sheets included or will include any untrue statement resulting directly from any Mortgage Pool Error (except any Corrected Mortgage Pool Error, with respect to materials prepared after the receipt by such Underwriter from the Depositor of notice of such Corrected Mortgage Pool Error or materials superseding or correcting such Corrected Mortgage Pool Error).

(c)     The Underwriters shall cause a firm of public accountants to furnish to the Depositor a letter dated as of the date on which the Underwriters deliver any Computational Materials (which term shall be deemed to include, for purposes of this paragraph (c), calculated statistical information delivered to prospective investors in the form of a Structural Term Sheet) to the Depositor pursuant to Section 8(a), in form and substance satisfactory to the Depositor, stating in effect that they have verified the mathematical accuracy of any calculations performed by each Underwriter and net forth in such Computational Materials.

(d)     Each Underwriter agrees that it will not represent to investors that any Computational Materials or Structural Term Sheets were prepared or disseminated on behalf of the Depositor.

(e)     If, at any time when a Prospectus relating to the Notes of a Series is required to be delivered under the Act, it shall be necessary to amend or supplement the related Prospectus as a result of an untrue statement of a material fact contained in any Computational Materials or Structural Term Sheets provided by any Underwriter pursuant to this Section 8 or the omission to state therein a material fact required, when considered in conjunction with the related Prospectus and Prospectus Supplement, to be stated therein or necessary to make the statements therein, when read in conjunction with the related Prospectus and Prospectus Supplement, not misleading, or if it shall be necessary to amend or supplement any Current Report relating to any Computational Materials or Structural Term Sheets to comply with the Act or the rules thereunder, such Underwriter promptly will prepare and furnish to the Depositor for filing with the Commission an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.  Each Underwriter represents and warrants to the Depositor, as of the date of delivery by it of such amendment or supplement to the Depositor, that such amendment or supplement will not include any untrue statement of a material fact or, when read in conjunction with the related Prospectus and Prospectus Supplement, omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that each such Underwriter makes no representation or warranty as to whether any such amendment or supplement will include any untrue statement resulting directly from any Mortgage Pool Error (except any Corrected Mortgage Pool Error, with respect to any such amendment or supplement prepared after the receipt by such Underwriter from the Depositor of notice of such Corrected Mortgage Pool Error or materials superseding or correcting such Corrected Mortgage Pool Error).  The Depositor shall have no obligation to file such amendment or supplement if the Depositor determines that (i) such amendment or supplement contains any untrue statement of a material fact or, when read in conjunction with the related Prospectus and Prospectus Supplement, omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading; it being understood, however, that the Depositor shall have no obligation to review or pass upon the accuracy or adequacy of, or to correct, any such amendment or supplement provided by any Underwriter to the Depositor pursuant to this paragraph (e) or (ii) such filing is not required under the Act.

 9.      Collateral Term Sheets.

(a)     Prior to the delivery of any "Collateral Term Sheet within the meaning of the PSA Letter, the filing of which material is a condition of the relief granted in such letter (such material being the "Collateral Term Sheets"), to a prospective investor in the Notes, the Underwriters shall notify the Depositor and its counsel by telephone of their intention to deliver such materials and the approximate date on which the first such delivery of such materials is expected to occur.  Not later than 2:00 p.m., New York time, on the business day immediately following the date on which any Collateral Term Sheet was first delivered to a prospective investor in the Notes; the Underwriters shall deliver to the Depositor five complete copies of all materials provided by the Underwriters to prospective investors in such Notes which constitute "Collateral Term Sheets." Each delivery of a Collateral Term Sheet to the Depositor pursuant to this paragraph (a) shall be effected by delivering four copies of such materials to counsel for the Depositor on behalf of the Depositor and one copy of such materials to the Depositor.  (Collateral Term Sheets and Structural Term Sheets are, together, referred to herein as "ABS Term Sheets.") At the time of each such delivery, the Underwriter making such delivery shall indicate in writing that the materials being delivered constitute Collateral Term Sheets, and, if there has been any prior such delivery with respect to the related Series, shall indicate whether such materials differ in any material respect from any Collateral Term Sheets previously delivered to the Depositor with respect to such Series pursuant to this Section 9(a) as a result of the occurrence of a material change in the characteristics of the related Mortgage Loans.

(b)     Each Underwriter represents and warrants to and agrees with the Depositor as of the date of the related Terms Agreement and as of the Closing Date, that:

(i)

The Collateral Term Sheets furnished to the Depositor by such Underwriter pursuant to Section 9(a) constitute all of the materials furnished to prospective investors by such Underwriter prior to time of delivery thereof to the Depositor that are required to be filed with the Commission as "Collateral Term Sheets" with respect to the related Notes in accordance with the PSA Letter, and such Collateral Term Sheets comply with the requirements of the PSA Letter;

(ii)

On the date any such Collateral Term Sheets with respect to such Notes were last furnished to each prospective investor by such Underwriter and on the date of delivery thereof to the Depositor pursuant to Section 9(a) and on the related Closing Date, such Collateral Term Sheets did not and will not include any untrue statement of a material fact or, when read in conjunction with the Prospectus and Prospectus Supplement, omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

(iii)

such Underwriter has not represented to any prospective investor that any Collateral Term Sheets with respect to any Series were prepared or disseminated on behalf of the Depositor, and, except as otherwise disclosed by such underwriter to the Depositor in writing prior to the date hereof, all Collateral Term Sheets previously furnished to prospective investors included a disclaimer to the effect set forth in Section 9(c).

Notwithstanding the foregoing, each underwriter makes no representation or warranty as to whether any Collateral Term Sheet included or will include any untrue statement or material omission resulting directly from any Mortgage Pool Error (except any Corrected Mortgage Pool Error, with respect to materials prepared after the receipt by such Underwriter from the Depositor of notice of such Corrected Mortgage Pool Error or materials superseding or correcting such Corrected Mortgage Pool Error).

(c)     Each Underwriter acknowledges and agrees that any Collateral Term Sheets with respect to any Series of Notes furnished to prospective investors from and after the date hereof shall include a disclaimer in form satisfactory to the Depositor to the effect set forth in Section 8(b)(iv) hereof, and to the effect that the information contained in such materials supersedes information contained in any prior Collateral Term Sheet with respect to such series of Notes and will be superseded by the description of the related mortgage Loans in the related Prospectus Supplement and in the Detailed Description relating to such Prospectus Supplement to be filed under cover of Form 8-K.  Each Underwriter agrees that it will not represent to prospective investors that any Collateral Term Sheets were prepared or disseminated on behalf of the Depositor.

(d)     If, at any time when a prospectus relating to the Notes of a Series is required to be delivered under the Act, it shall be necessary to amend or supplement the related Prospectus as a result of an untrue statement of a material fact contained in any Collateral Term Sheets provided by any Underwriter pursuant to this Section 9 or the omission to state therein a material fact required, when considered in conjunction with the related Prospectus and Prospectus Supplement, to be stated therein or necessary to make the statements therein, when read in conjunction with the related Prospectus and Prospectus Supplement, not misleading, or if it shall be necessary to amend or supplement any Current Report relating to any Collateral Term Sheets to comply with the Act or the rules thereunder, such Underwriter promptly will prepare and furnish to the Depositor for filing with the Commission and amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.  Each Underwriter represents and warrants to the Depositor, as of the date of delivery of such amendment or supplement to the Depositor, that such amendment or supplement will not include any untrue statement of a material fact or, when read in conjunction with the related Prospectus and Prospectus Supplement, omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that each such Underwriter makes no representation or warranty as to whether any such amendment or supplement will include any untrue statement resulting directly from any Mortgage Pool Error (except any Corrected Mortgage Pool Error, with respect to any such amendment or supplement prepared after the receipt by such Underwriter from the Depositor of notice of such Corrected Mortgage Pool Error or materials superseding or correcting such Corrected Mortgage Pool Error).  The Depositor shall have no obligation to file such amendment or supplement if the Depositor determines that (i) such amendment or supplement contains any untrue statement of a material fact or, when read in conjunction with the related Prospectus and Prospectus Supplement, omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading; it being understood, however, that the Depositor shall have no obligation to review or pass upon the accuracy or adequacy of, or to correct, any such amendment or supplement provided by any Underwriter to the Depositor pursuant to this paragraph (d) or (ii) such filing is not required under the Act.

 10.      Default of Underwriters.  If any underwriter or Underwriters participating in an offering of Notes default in their obligations to purchase Notes hereunder and under the Terms Agreement and the aggregate principal amount of such Notes which such defaulting Underwriter or Underwriters agreed, but failed to purchase does not exceed 10% of the total principal amount of the Notes set forth in such Terms Agreement, you may make arrangements satisfactory to the Depositor for the purchase of such Notes by other persons, including any of the Underwriters participating in such offering, but if no such arrangements are made within a period agreed to by you and the Depositor after the applicable Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective total commitments hereunder and under such Terms Agreement, to purchase the Notes which such defaulting Underwriters agreed but failed to purchase.  If any Underwriter or Underwriters so default and the aggregate principal amount of Notes with respect to which such default or defaults occur is more than 10% of the total principal amount of the Notes set forth in such Terms Agreement and arrangements satisfactory to you and the Depositor for the purchase of such Notes by other persons are not made within such period agreed to by you and the Depositor after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 12.  As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section.  Nothing herein will relieve a defaulting Underwriter from liability for its default.

 11.      Survival of Certain Representations and Obligations.  The respective indemnities, agreements, representations, warranties and other statements by the Depositor or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters, the Depositor or any of their respective officers or directors or any controlling person, and will survive delivery of and payment for the Notes.

 12.      Termination of Agreement.  You, as Representative of the Underwriters named in any Terms Agreement, may also terminate such Terms Agreement, immediately upon notice to the Depositor, at any time at or prior to the applicable Closing Date, (i) if there has been, since the date of such Terms Agreement or since the respective dates as of which information is given in the Registration Statement or Prospectus, any change or any development involving a prospective change, in or affecting the condition, financial or otherwise, earnings, affairs or business of the Depositor or the Trust, whether or not arising in the ordinary course of business, which in your judgment would materially impair the market for, or the investment quality of, the Notes, or (ii) if there has occurred any outbreak 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 your judgment, impracticable to market the Notes or enforce contracts for the sale of the Notes; or (iii) if trading generally on either the New York Stock Exchange or the American Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by either of said exchanges or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either federal, New York or California authorities.  In the event of any such termination, (A) the covenants set forth in Section 5 with respect to any offering of Notes shall remain in effect so long as the Underwriters own any such Notes purchased from the Depositor pursuant to the applicable Terms Agreement and (B) the covenant set forth in Section 5(b), the indemnity agreement set forth in Section 7, the contribution provisions set forth in Section 13, and the provisions of Sections 16 and 17 shall remain in effect.

If this Agreement is terminated pursuant to Section 10 or if for any other reason the purchase of the Notes by the Underwriters is not consummated, the Depositor shall remain responsible for the expenses to be paid or reimbursed to them pursuant to Section 5(h), and the obligations of the Depositor and the Underwriters pursuant to Section 7 shall remain in effect.

 13.      Contribution.  In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 7 is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Depositor, on the one hand, and the Underwriters, on the other, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Depositor and one or more of the Underwriters, as follows:

(a)     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 Computational Materials or ABS Term Sheets (or any amendments or supplements thereof), in such proportion so that the Underwriters are responsible for that portion represented by the difference between the proceeds to the Depositor in respect of the Notes appearing on the cover page of the Prospectus for the related Series and the total proceeds received by the Underwriters from the sale of such Notes (the "Underwriting Discount"), and the Depositor is responsible for the balance; provided, however, that in no case shall the Underwriters be responsible under this subparagraph (i) for any amount in excess of such Underwriting Discount applicable to the Notes purchased by the Underwriters pursuant to this Agreement and the related Terms Agreement; and
