Explanation of Responses:
( 1)	86% of par (i.e., $21,500 per share).
( 2)	Consistent with the Securities and Exchange Commission's Auction Rate Securities Global Exemptive Relief no action letter issued on September 22, 2008, the shares reported herein represent the reporting person's combined holdings in the separate series of preferred shares of the issuer.
( 3)	These shares were mandatorily redeemed by the Issuer on January 5, 2011.
( 4)	These shares were mandatorily redeemed at par (i.e., $25,000 per share).
( 5)	These shares were mandatorily redeemed by the Issuer on January 7, 2011.

Remarks:
(+) The Issuer mandatorily redeemed certain preferred shares covered by this filing in transactions dated January 5, 2011 and January 7, 2011. The prior Form 4 filing submitted by the reporting person on January 28, 2011 reflected only the January 5, 2011 redemption and, due to an oversight, did not reflect the redemption that took place as of January 7. The sole purpose of this amendment filing is to correct this error.
