DEREGISTRATION OF SECURITIES

        On October 18, 1999, Hispanic Broadcasting Corporation, a Delaware corporation ("Hispanic"), HBC Capital Trust I, a Delaware business trust, and HBC Capital Trust II, a Delaware business trust, filed a shelf Registration Statement on Form S-3 (No. 333-89235) for purposes of registering up to $1.5 billion, in the aggregate, of their respective debt and equity securities to be sold, from time to time, in one or more offerings. Since that time, and from time to time, Hispanic has filed prospectus supplements under the Registration Statement when selling securities "off the shelf" from the Registration Statement.

        On June 11, 2002, Hispanic entered into that certain Agreement and Plan of Reorganization (the "Merger Agreement") with Univision Communications, Inc., a Delaware corporation ("Univision"), and Univision Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of Univision ("Merger Sub"). Pursuant to the Merger Agreement, Merger Sub will merge with and into Hispanic with Hispanic being the surviving company (the "Merger"). In the Merger, each of the holders of the capital stock of Hispanic will receive 0.85 shares of Class A common stock, par value $0.01 per share, of Univision in exchange for each share of capital stock of Hispanic. Following the Merger, Hispanic will be a wholly-owned subsidiary of Univision and ineligible to file a registration statement on Form S-3.

        On the date hereof, Hispanic has filed a Form 15 pursuant to the Securities Exchange Act of 1934 to terminate the registration of its Class A common stock, par value $0.001 per share, under Section 12(g) of the Securities Exchange Act of 1934.

        Accordingly, this Post Effective Amendment No. 1 to the Registration Statement is being filed to deregister, as of the date hereof, all of the debt and equity securities that remain unsold under the Registration Statement.
