We do not know when or in what amounts a selling stockholder may offer shares for sale. The selling stockholders may not sell any or all of the shares offered by the prospectus or this prospectus supplement. Because the selling stockholders may offer all or some of the shares pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by the prospectus or this prospectus supplement will be held by the selling stockholders.

For each selling stockholder, this number represents the percentage of Class A common stock to be owned by such selling stockholder after completion of the offering, based on the number of shares of Class A common stock outstanding as of March 3, 2009 (45,646,015 shares).
