Introductory Note

Lehman ABS Corporation (the “Depositor”) is the Depositor in respect of the Corporate Backed Trust Certificates, Goldman Sachs Capital I Securities-Backed Series 2004-6 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 March 19, 2004 in respect of the Trust. The Trust’s assets consist solely of capital Securities issued by Goldman Sachs Capital I (the “Underlying Securities Issuer”). The Certificates do not represent obligations of, or interests in, the Depositor or the Trustee.

The Depositor is a wholly-owned, indirect subsidiary of Lehman Brothers Holdings Inc. (“LBHI”). On September 15, 2008 and periodically thereafter, LBHI and certain of its subsidiaries (collectively, the “Debtors”) commenced voluntary cases under chapter 11 of title 11 of the United States Code with the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) (jointly administered proceedings, In re Lehman Brothers Holdings Inc. et al., Case Number 08-13555). LBHI and 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 6, 2011, the Bankruptcy Court entered an order (the “Confirmation Order”) confirming the Modified Third Amended Joint Chapter 11 Plan of Lehman Brothers Holdings Inc. and its Affiliated Debtors (the “Plan”). The Plan and the Confirmation Order were attached as Exhibit 2.1 and Exhibit 2.2, respectively, to LBHI’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 14, 2011. LBHI’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 14, 2011 contains a summary of the Plan.

On March 6, 2012 (the “Effective Date”), the Plan became effective and a notice of the Effective Date of the Plan (the “Notice of Effective Date”) was filed with the Bankruptcy Court.

The Goldman Sachs Group, Inc., the issuer of the junior subordinated debentures, the sole assets held by the Underlying Securities Issuer, is subject to the information reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For information on The Goldman Sachs Group, Inc., please see its periodic and current reports filed with the Securities and Exchange Commission (the “Commission”) under The Goldman Sachs Group, Inc.’s Exchange Act file number, 001-14965. 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 regarding issuers filed electronically through the Electronic Data Gathering, Analysis and Retrieval system, or “EDGAR.” Periodic and current reports and other information 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.
