  (1)    Approximately 10.83% of the shares represented are held in escrow in the event of any purchase price adjustment and as security for certain indemnification obligations of Red Swoosh under the terms of the Agreement and Plan of Merger, dated March 23, 2007, governing Akamai’s acquisition of Red Swoosh and a related Escrow Agreement. Unless required to be returned to Akamai under the terms and conditions of the Agreement and Plan of Merger and the Escrow Agreement, these shares are eligible for release on October 12, 2008.
 
  (2)   We do not know when or in what amounts a selling stockholder may offer shares for sale. The selling stockholders might not sell any or all of the shares offered by this prospectus. 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 this prospectus will be held by the selling stockholders.
