Introductory Note

Lehman ABS Corporation (the “Depositor”) is the Depositor in respect of the Corporate Backed Trust Certificates, Duke Capital Note-Backed Series 2003-3 Trust (the “Trust”), a common law trust formed pursuant to the Standard Terms for Trust Agreements, dated as of January 16, 2001, between the Depositor and U.S. Bank Trust National Association, as trustee (the “Trustee”), as supplemented by a Series Supplement (the “Series Supplement”) dated as of January 31, 2003 in respect of the Trust. The Trust’s assets consist solely of senior notes issued by Duke Capital Corporation, predecessor to Spectra Energy Capital, LLC. The Certificates do not represent obligations of or interests in the Depositor or the Trustee.

The Registrant is a wholly-owned, indirect subsidiary of Lehman Brothers Holdings Inc. (“LBHI”), which filed a voluntary petition (the “Petition”) for relief under Chapter 11 of the United States Code in the United States Bankruptcy Court for the Southern District of New York on September 15, 2008 in a jointly administered proceeding named In re Lehman Brothers Holdings Inc., et. al. under Case Number 08-13555. LBHI and its wholly-owned broker-dealer, Lehman Brothers Inc., have sold since September 15, 2008 significant businesses, including the sale on September 21, 2008 of the investment banking business to Barclays Capital Inc., which business included the employees who historically conducted the Registrant’s business.

On December 14, 2007, Spectra Energy Capital, LLC, the successor-in-interest to the issuer of the underlying securities and a wholly-owned subsidiary of Spectra Energy Corp (“Spectra Energy”), entered into a supplemental indenture with Spectra Energy pursuant to which Spectra Energy has agreed to fully and unconditionally guarantee the payment of principal and interest under all series of notes of the underlying issuer including the underlying securities. As a result, the underlying securities issuer has ceased its reporting under Sections 13(a) and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and will no longer file current and periodic reports with the Securities and Exchange Commission.

Spectra Energy Corp, the underlying securities guarantor, is subject to the information reporting requirements of the Exchange Act. For information on the issuer of the underlying securities, please see its periodic and current reports filed with the Securities and Exchange Commission (the “Commission”) under Spectra Energy Corp’s Exchange Act file number, 001-33007. The Commission maintains a site on the World Wide Web at “http://www.sec.gov” at which users can view and download copies of reports, proxy and information statements and other information filed electronically through the Electronic Data Gathering, Analysis and Retrieval system, or “EDGAR.” Periodic and current reports and other information regarding issuers required to be filed pursuant to the Exchange Act by the issuer of the underlying securities may be accessed on this site. Neither the Depositor nor the Trustee has participated in the preparation of such reporting documents, or made any due diligence investigation with respect to the information provided therein. Neither the Depositor nor the Trustee has verified the accuracy or completeness of such documents or reports. There can be no assurance that events affecting the issuer of the underlying securities or the underlying securities have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.
