(2)	These derivative securities (stock options) vest ratably on each of the first, second and third anniversaries of the date of grant.
(3)	These restricted units vest ratably on each of the third, fifth, seventh, and tenth anniversaries of the date of grant. Restricted units are settled in shares of the Company's common stock upon vesting.
(4)	On the third anniversary of the date of grant, these restricted units vest conditionally based on the average of the closing price of the Company's common stock on the last 40 trading days of 2009 ("Stock Price") as follows: 25,000 restricted units vest if the Stock Price is $6.75 or less; 50,000 restricted units vest if the Stock Price is $8.50; and 75,000 restricted units if the Stock Price is $10.25 or greater.
