                               UNAUDITED PRO FORMA
                     COMBINED CONDENSED FINANCIAL STATEMENTS

      On June 10, 2005, Akamai Technologies, Inc. (the "Company" or "Akamai")
acquired privately held Speedera Networks, Inc. ("Speedera"). The Company
acquired all of the outstanding common and preferred stock, including vested and
unvested stock options, of Speedera in exchange for approximately 10.6 million
shares of Akamai common stock and 1.7 million Akamai stock options. The
aggregate purchase price, net of cash received, was approximately $143.2
million, which consisted of $122.1 million in shares of common stock, $18.4
million in fair value of the Company's stock options and transaction costs of
$2.7 million, which primarily consisted of fees for financial advisory and legal
services. The purchase price allocation is preliminary and a final determination
of required purchase accounting adjustment will be made upon the completion of
the Company's evaluation of the assets acquired and liabilities assumed.

      The unaudited combined condensed pro forma balance sheet as of March 31,
2005 is based on the individual balance sheets of Akamai and Speedera and
prepared as if the acquisition of Speedera had occurred on March 31, 2005. The
unaudited combined condensed pro forma statements of operations for the year
ended December 31, 2004 and for the three months ended March 31, 2005, were
prepared as if the acquisition of Speedera had occurred on January 1, 2004.

      The unaudited pro forma adjustments are based upon available information
and assumptions that Akamai believes are reasonable. The unaudited pro forma
combined condensed consolidated financial statements and related notes thereto
should be read in conjunction with Akamai's historical consolidated financial
statements as previously filed on Akamai's Annual Report on Form 10-K for the
year ended December 31, 2004, filed with the Securities and Exchange Commission
(the "Commission") on March 16, 2005 and the Quarterly Report on Form 10-Q for
the three months ended March 31, 2005, filed with the Commission on May 10,
2005. In addition, this unaudited combined condensed pro forma information
should be read in conjunction with the historical condensed consolidated
financial statements of Speedera included within this Amendment to Current
Report on Form 8-K/A. The historical income statement of Speedera for the twelve
months ended December 31, 2004 is based on combining the last six months of
results of operation from Speedera's fiscal year ended June 30, 2004 with the
first six months of results of operations from Speedera's fiscal year ended June
30, 2005.

      These unaudited combined condensed pro forma financial statements are
prepared for informational purposes only and are not necessarily indicative of
future results or of actual results that would have been achieved had the
acquisition of Speedera been consummated as of January 1, 2004 for the unaudited
combined condensed pro forma statements of operations and as of March 31, 2005
for the unaudited combined condensed pro forma balance sheets. The pro forma
financial statements do not give effect to any cost savings or incremental costs
that may result from the integration of Akamai and Speedera.

NOTE 1 - BASIS OF PRESENTATION

      The unaudited pro forma combined condensed statements of operations for
the year ended December 31, 2004 and for the three months ended March 31, 2005
give effect to the acquisition of Speedera by Akamai as if the acquisition had
occurred on January 1, 2004. The unaudited pro forma combined condensed balance
sheet as of March 31, 2005 gives effect to the above-mentioned acquisition as if
it had occurred on March 31, 2005.

      The unaudited combined condensed pro forma financial information has been
prepared on the same basis as Akamai's audited financial statements. The
acquisition was accounted for using the purchase method of accounting and,
accordingly, the respective assets acquired and liabilities assumed have been
recorded at their fair value and consolidated into the net assets of Akamai.

      A summary of the preliminary purchase price allocation for the acquisition
as if the purchase had occurred on March 31, 2005 is as follows (in thousands):

</TABLE>

      Based upon the purchase price allocation, the total purchase price
exceeded the net assets acquired and liabilities assumed when adjusted to fair
market value and resulted in goodwill in the pro forma combined condensed
financial information of approximately $92.8 million. The identified intangible
assets acquired, including completed technologies, customer relationships and
non-compete agreements were assigned fair values based upon an appraisal and
totaled $43.2 million in aggregate.

NOTE 2 - PRO FORMA ADJUSTMENTS

      Adjustments have been made to the unaudited pro forma combined financial
information to reflect the following:

(A)   The elimination of the historic stockholders' deficit of Speedera.

(B)   The fixed assets were recorded at estimated fair market value of $2.8
      million.

(C)   Record goodwill of $92.8 million for excess of the purchase price over the
      preliminary fair values of the assets acquired less the liabilities
      assumed.

(D)   Record the preliminary estimate of fair value for intangible assets
      determined at the time of acquisition of $43.2 million. The following are
      identified intangible assets acquired and the respective estimated useful
      lives over which the assets will be amortized:

        The completed technologies and the non-compete agreements will be
        amortized on a straight-line basis over their expected useful lives. The
        customer relationships will be amortized at the ratio that current

        estimated revenues to be generated from those relationships from the
        date of acquisition. Annual amortization expense from the customer
        relationships is expected to be $5.4 million for the remainder of 2005
        and $6.6 million, $5.2 million, $4.5 million, $3.7 million and $3.1
        million for each of the next five fiscal years, respectively.

(E)   Represents adjustment of deferred revenue to fair market value.

(F)   Reflects accruals for Akamai's direct costs of the acquisition of $1.4
      million, $1.7 million of accrued restructuring liabilities consisting of
      employee severance and outplacement costs and $3.8 million of Speedera's
      transaction costs due at the acquisition date.

(G)   Record income taxes based on statutory rates applied to the net effect of
      changes in the results of operations.

(H)   Represents the amortization expense related to identified intangible
      assets acquired.

      million and reduction in related interest expense during the pro forma
      periods presented that was repaid at the time of acquisition, which is
      directly attributable to the business combination.

(J)   Record depreciation expense for acquired fixed assets based on the
      estimate of fair values determined at the time of acquisition.
      Depreciation expense is calculated on straight-line basis over estimated
      useful lives of 12 to 48 months. As a result of recording Speedera's fixed
      assets at estimated fair market value, the depreciation expense included
      in the pro forma adjustments column was reduced for the periods presented
      in the pro forma statements of operations.


(K)   Record deferred compensation of $9.7 million related to the intrinsic
      value allocated to the unvested options issued in the acquisition that had
      yet to be earned as of the acquisition date.

(L)   Record deferred compensation expense related to options issued in the
      acquisition which had been earned over the periods presented in the
      statement of operations included in the unaudited pro forma combined

NOTE 3 - NET INCOME PER SHARE

      Pro forma basic net income per share is computed using the weighted
average number of common shares outstanding during the applicable quarter and
assumes that common shares for the business combination were issued at the
beginning of the period presented. Pro forma diluted net income per share is
computed using the weighted average number of common shares outstanding during
the quarter, assuming the common shares for the business combination were issued
at the beginning of the periods presented, plus the dilutive effect of potential
common stock. Potential common stock consists of stock options, deferred stock
units, warrants, unvested restricted common stock and convertible notes.

      The following table sets forth the components used in the computation of
pro forma basic and diluted net income per common share (in thousands, except
per share data):
