(1) Approximately 39% of the shares represented are held in escrow as security for certain indemnification obligations of Netli and to secure funds to reimburse the Representative of the former Netli stockholders for fees and expenses incurred in connection with the performance of his obligations, each under the terms of the Agreement and Plan of Merger, dated February 2, 2007, governing Akamai’s acquisition of Netli 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 in stages at various times prior to September 17, 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.
