The price set forth in this column represents the market price of Common Stock on the date that shares of TVDS owned by the Reporting Person vested and therefore the date that additional shares of Common Stock relating to dividends were earned. This is the market price of Common Stock on the date that the shares of TVDS owned by the Reporting Person vested and was therefore the price used to calculate the number of shares deducted to satisfy tax withholding obligations. Upon vesting, each share of TVDS converts into one share of Common Stock. The shares of TVDS vest 20% per year on each of the first five anniversaries of the date of grant, which was 03/19/09.
