that the Depositor and the Trustee have complied, in all material respects, with the provisions of the Standard Terms for Trust Agreements dated as of January 16, 2001, as supplemented by a series supplement dated as of April 30, 2004 (together, the
Trust Agreement) in respect of the Corporate Backed Trust Certificates, Goldman Sachs Capital I Securities-Backed Series 2004-7 Trust (the Trust), during the period covered by the annual report on Form 10-K filed by the
Depositor on behalf of the Trust for the year ended December 31, 2013 (the Annual Report). Management is responsible for compliance with the Trust Agreement. Our responsibility is to express an opinion on Managements assertions
based on our examination.

the Trustees compliance with the Trust Agreement and performing such other procedures as considered necessary in the circumstances. We believe that our examination provides a reasonable basis for our opinion.

encumbrances, or adverse interests have been placed upon the assets of the Trust.
