        <footnote id="F1">Such stock options will have an effective date of February 9, 2007, and the exercise price will be equal to the closing sale price of Akamai's common stock as reported on the Nasdaq Global Select Market on that date.  Due to a typographical error, the original Form 4 filing erroneously identified the effective date as February 9, 2006.</footnote>
        <footnote id="F2">Option vests as follows:  25% on February 9, 2008; and the remaining 75% vests in equal installments of 6.25% each quarter thereafter.</footnote>
