Explanation of Responses:
( 1)	The securities reported on this Form 3 are subject to repurchase under the terms of Merrill Lynch & Co.'s ("MLCO") settlement with the Securities and Exchange Commission (the "Commission"), et alia, with respect to certain auction rate securities ("Subject Securities") sold by MLCO and/or held by customers in accounts at MLCO. The repurchases of the Subject Securities by MLCO, and the reporting of its holdings of such Subject Securities by MLCO, are being made in reliance on the Auction Rate Securities-Global Relief Letter issued by the Commission on September 22, 2008 (the "Relief Letter"). In reliance on the Relief Letter, we are reporting our holdings of each series of preferred stock of the issuer on a consolidated basis as a single class of securities.
( 2)	In further reliance on the Relief Letter, we will not file Forms 4 to report changes in our beneficial ownership of the issuer's preferred stock. However, in compliance with the terms of the Relief Letter, we hereby undertake to provide upon request by the Commission, the issuer or a security holder of the issuer, complete information regarding the number of equity securities of the issuer purchased or sold at each different price and date of all transactions in such securities that occurred after we became a 10% owner but prior to the date of this filing.
( 3)	Merrill Lynch & Co., Inc. indirectly through its wholly-owned subsidiary Merrill Lynch, Pierce, Fenner & Smith Incorporated owns 598 shares of the issuer's preferred stock.
