You can read and copy these reports and other information at the public reference facilities maintained by the SEC at Room 1580, 100 F Street, N.E., Washington, D.C. 20549. You may obtain copies of this material for a fee by writing to the SEC’s Public Reference Section of the SEC at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information about the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. You can also access some of this information electronically by means of the SEC’s website on the Internet at http://www.sec.gov, which contains reports, proxy and information statements and other information that the respective underlying securities issuers have filed electronically with the SEC. The underlying securities issuer DaimlerChrysler North America Holding Corp. (now known as Daimler Finance North America LLC) and the guarantor, Daimler AG, no longer file periodic Exchange Act reports. Unless and until the underlying securities comprise 10% of the assets held by the trust, the trust is not required to liquidate its holdings of the asset. If such circumstances were to occur, such as an increase in concentration of DaimlerChrysler assets to at least 10% of total trust assets, the asset would have to be liquidated.

Although we have no reason to believe the information concerning the underlying securities or the underlying securities issuers contained in the underlying securities issuers’ Exchange Act reports is not reliable, neither the depositor nor the trustee participated in the preparation of such documents or made any due diligence inquiry with respect to the information provided therein. No investigation with respect to the underlying securities issuers (including, without limitation, no investigation as to their financial condition or creditworthiness) or of the underlying securities has been made. You should obtain and evaluate the same information concerning the respective underlying securities issuers as you would obtain and evaluate if you were investing directly in the respective underlying securities or in other securities issued by the respective underlying securities issuers. There can be no assurance that events affecting the respective underlying securities or the respective underlying securities issuers have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.
