Re:

Structured Asset Securities Corporation,

Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel for Structured Asset Securities Corporation, a Delaware corporation (the “Company”), in connection with the offering of the Lehman XS Trust Mortgage Pass-Through Certificates, Series 2006-8 (the “Certificates”). A Registration Statement of the Company on Form S-3 relating to the Certificates (Commission File No. 333-129480) has been filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) and was declared effective on March 31, 2006. As set forth in the prospectus dated April 3, 2006, as supplemented by a prospectus supplement dated May 30, 2006 (the “Base Prospectus” and the “Prospectus Supplement,” respectively), the Certificates will be issued under and pursuant to the conditions of a trust agreement dated as of May 1, 2006 (the “Trust Agreement”), by and among the Company, as depositor, Aurora Loan Services LLC, as master servicer (the “Master Servicer”), and LaSalle Bank National Association, as trustee (the “Trustee”).

We have examined a form of the Trust Agreement, forms of the Certificates, the Base Prospectus, the Prospectus Supplement, and originals or copies, certified or otherwise identified to our satisfaction, of such instruments, certificates, records and other documents, and have made such examination of law, as we have deemed necessary or appropriate for the purpose of this opinion. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies or by facsimile or other means of electronic transmission, and the authenticity of the originals of such latter documents. As to facts relevant to the opinions expressed herein and the other statements made herein, we have relied, to the extent we have deemed appropriate, upon certificates and oral or written statements and representations of officers and other representatives of the Company and others.

Based upon the foregoing, we are of the opinion that:

(i)

The Trust Agreement has been duly and validly authorized by all necessary action on the part of the Company and, when duly executed and delivered by the Company, the Trustee, the Master Servicer, and any other party thereto, the Trust Agreement will constitute a legal, valid and binding agreement of the Company, enforceable against it in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally and to general equitable principles (regardless of whether considered in a proceeding in equity or at law), including concepts of commercial reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, and with respect to the rights of indemnity or contribution, as may be limited by public policy considerations;

(ii)

The issuance and sale of the Certificates have been duly authorized by all requisite corporate action on the part of the Company and, when duly and validly executed and authenticated in accordance with the terms of the Trust Agreement and delivered against payment therefor pursuant to the underwriting agreement dated August 23, 2005, between the Company and Lehman Brothers Inc., and a terms agreement dated May 30, 2006 between the Company and Lehman Brothers Inc., the Certificates will be duly and validly issued and outstanding, and entitled to the benefits of the Trust Agreement;

(iii)

Under existing law, assuming compliance with all provisions of the Agreement, for federal income tax purposes, the pool of assets for which the Trust Agreement directs that a REMIC election be made will qualify as a "real estate mortgage investment conduit” (“REMIC”) pursuant to Section 860D of Revenue Code of 1986, as amended (the “Code”); each of the Certificates, other than the Class LT-R and Class R and exclusive of the rights to receive (or obligation to pay) Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls (as such terms are defined in the Trust Agreement), will represent ownership of “regular interests” in a REMIC within the meaning of the Code; the Basis Risk Reserve Fund and the Supplemental Interest Trust each represent an “outside reserve fund” pursuant to Treasury Regulation §1.860G-2(h) that is beneficially owned by the beneficial owners of the Class X Certificates; the rights of the Certificates (other than of the Class X, Class R, Class LT-R and Class P Certificates) to receive Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls represent contractual rights in an interest rate cap contract; and the Class LT-R and Class R Certificates will be considered to represent REMIC “residual interests” within the meaning of Section 860G(a)(2) of the Code; and

(iv)

The statements contained under the caption “Material Federal Income Tax Considerations” in the Base Prospectus and the Prospectus Supplement, insofar as such statements constitute conclusions of law, are true and correct in all material respects as set forth therein.

The opinions set forth in subparagraphs (iii) and (iv) are based upon the existing provisions of the Code and Treasury regulations issued or proposed thereunder, published Revenue Rulings and releases of the Internal Revenue Service and existing case law, any of which could be changed at any time. Any such changes may be retroactive in application and could modify the legal conclusions upon which such opinions are based. The opinions expressed herein are limited as described above, and we do not express an opinion on any other tax aspect of the transactions contemplated by the documents referenced above.

In rendering the foregoing opinions, we express no opinion as to the laws of any jurisdiction other than the federal laws of the United States of America and the laws of the State of New York.

We hereby consent to the filing of this letter and to the references to this firm under the headings “Legal Matters” and “Material Federal Income Tax Considerations” in the Base Prospectus and Prospectus Supplement, without implying or admitting that we are “experts” within the meaning of the Securities Act or the rules and regulations of the Commission issued thereunder, with respect to any part of the Base Prospectus or the Prospectus Supplement.

Very truly yours,

/s/ McKee Nelson LLP
