(1) The original transaction was effected pursuant to a Rule 10b5-1 trading plan. On June 6, 2005, the reporting person entered into a prepaid variable forward contract with a securities brokerage firm. Under the relevant contract, the reporting person had to deliver up to the 10,000 shares of the Issuer's common stock referenced in column 7 of Table II to the securities brokerage firm on June 6, 2007. The number of shares the reporting person had to deliver on such date was a function of the closing price of the Issuer's common stock on such date. The amounts that would be in columns 2 and 8 of Table II were also a function of, among other things, the closing price of the Issuer's common stock on June 6, 2007. Such prepaid variable forward contract terminated by its terms on June 6, 2007 and pursuant to its terms all 10,000 shares of the Issuer's common stock that were subject to such prepaid variable forward contract were retained by the securities brokerage firm on June 6, 2007.
(2) The derivative security is a prepaid variable forward contract as referenced in footnote (1). $0.00 has been inserted to satisfy the requirements to submit this form via the EDGAR system.
