(1)	This reflects the closing price of InfoSpace, Inc.'s common stock on the NASDAQ Stock Market on December 28, 2007. This price does not reflect the fact that these shares are not eligible for the distribution of $9.00 per share payable on each share of common stock to shareholders of record as of December 10, 2007. Pursuant to NASDAQ Stock Market rules, the ex-dividend date for the distribution shall be one day after the payment date for such distribution, and therefore the price of the common stock has not yet adjusted for the amount of the distribution.
(2)	Shares of InfoSpace, Inc. common stock withheld by InfoSpace, Inc. to satisfy tax withholding obligation upon vesting of restricted stock units.
(3)	Each restricted stock unit represents the right to receive, following vesting, one share of InfoSpace, Inc. common stock.
