The foregoing spreadsheet allows you to calculate an example of the number of new options or restricted stock units that you would be eligible to receive in this offer for your eligible options at specified exchange ratios. To determine the numbers, you will need to input the number of eligible options that you hold in each price range, which will result in a calculation of the number of new options or restricted stock units. The exchange ratios above are based on application of the Black-Scholes value calculated using the average closing price of our common stock over the thirty (30) calendar day period ended January 28, 2009. The number of new options or restricted stock units that you will be eligible to receive in this offer for your eligible options will depend on the final exchange ratios, and we will notify you of the final exchange ratios following the expiration of the offer.
