                            AKAMAI TECHNOLOGIES, INC.

             AMENDED AND RESTATED 1999 EMPLOYEE STOCK PURCHASE PLAN

      This Amended and Restated 1999 Employee Stock Purchase Plan shall be
effective from and after June 1, 2005. The following constitute the provisions
of the Amended and Restated 1999 Employee Stock Purchase Plan of Akamai
Technologies, Inc.

      1. PURPOSE. The purpose of the Plan is to provide employees of the Company
and its Designated Subsidiaries with an opportunity to purchase Common Stock of
the Company through accumulated payroll deductions. It is the intention of the
Company to have the Plan qualify as an "Employee Stock Purchase Plan" under
Section 423 of the Internal Revenue Code of 1986, as amended. The provisions of
the Plan, accordingly, shall be construed so as to extend and limit
participation in a manner consistent with the requirements of that section of
the Code.

      2. DEFINITIONS.

            a. "Board" shall mean the Board of Directors of the Company.

            b. "Code" shall mean the Internal Revenue Code of 1986, as amended.

            c. "Common Stock" shall mean the Common Stock of the Company.

            d. "Company" shall mean Akamai Technologies, Inc. and any Designated
Subsidiary of the Company.

such as relocation allowances or travel expenses, whether specifically
designated as such or designated as signing bonuses, income or gains
attributable to restricted stock, stock options, stock appreciation rights or
other similar equity based compensation, imputed income for non cash items, such
as life insurance premiums, and similar items, whether or not specifically
itemized on the Form W-2. For avoidance of doubt, "Compensation" shall include
cash payments in respect of bonuses, commissions and other cash-based incentive
plans.

            f. "Designated Subsidiary" shall mean any Subsidiary which has been
designated by the Board from time to time in its sole discretion as eligible to
participate in the Plan.

            g. "Employee" shall mean any individual who is an Employee of the
Company for tax purposes whose customary employment with the Company is more
than five (5) months in any calendar year. For purposes of the Plan, the
employment relationship shall be



treated as continuing intact while the individual is on sick leave or other
leave of absence approved by the Company. Where the period of leave exceeds 90
days and the individual's right to reemployment is not guaranteed either by
statute or by contract, the employment relationship shall be deemed to have
terminated on the 91st day of such leave.

            or a national market system, including without limitation The Nasdaq
            National Market or The Nasdaq Small Cap Market of The Nasdaq Stock
            Market, its Fair Market Value shall be the closing sales price for
            such stock (or the closing bid, if no sales were reported) as quoted
            on such exchange or system for the last market trading day prior to
            the date of such determination, as reported in The Wall Street
            Journal or such other source as the Board deems reliable; or

            (ii) If the Common Stock is regularly quoted by a recognized
            securities dealer but selling prices are not reported, its Fair
            Market Value shall be the mean of the closing bid and asked prices
            for the Common Stock prior to the date of such determination, as
            reported in The Wall Street Journal or such other source as the
            Board deems reliable; or

            (iii) In the absence of an established market for the Common Stock,

            the Board.

            k. "Offering Periods" shall mean the periods of approximately six

Purchase Plan.

            m. "Purchase Price" shall mean 85% of the Fair Market Value of a
share of Common Stock on the Enrollment Date or on the Exercise Date, whichever
is lower; provided however, that, in the event (i) the Company's stockholders
approve an increase in the number of shares available for issuance under the
Plan, (ii) all or a portion of such additional shares are to be issued with
respect to one or more Offering Periods that are underway at the time of such
stockholder approval ("New Shares"), and (iii) the Fair Market Value of a share
of Common Stock on the date of such approval (the "Authorization Date FMV") is
higher than the Fair Market Value on the Enrollment Date for any such Offering
Period, the Purchase Price with



respect to New Shares shall be 85% of the Authorization Date FMV or the Fair
Market Value of a share of Common Stock on the Exercise Date, whichever is
lower.

            n. "Reserves" shall mean the number of shares of Common Stock
covered by each option under the Plan which have not yet been exercised and the

      3. ELIGIBILITY.

            a. Any Employee who shall be employed by the Company at least seven
(7) calendar days prior to a given Enrollment Date shall be eligible to
participate in the Plan.

            b. Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan:

            (i) to the extent that, immediately after the grant, such Employee
            (or any other person whose stock would be attributed to such
            Employee pursuant to Section 424(d) of the Code) would own capital
            stock of the Company and/or hold outstanding options to purchase
            such stock possessing five percent (5%) or more of the total
            combined voting power or value of all classes of the capital stock
            of the Company or of any Subsidiary, or

            (ii) to the extent that his or her rights to purchase stock under
            all employee stock purchase plans of the Company and its
            Subsidiaries accrues at a rate which exceeds Twenty-Five Thousand
            Dollars ($25,000) worth of stock (determined at the fair market
            value of the shares at the time such option is granted) for each
            calendar year in which such option is outstanding at any time.

      4. OFFERING PERIODS. A new Offering Period shall commence on the first
Trading Day on or after June 1 and December 1 of each year, or on such other
date as the Board shall determine, and continuing thereafter until the Plan is
terminated in accordance with Section 20 hereof. The Board shall have the power
to change the duration of Offering Periods (including the commencement dates
thereof) with respect to future offerings without stockholder approval if such
change is announced at least five (5) days prior to the scheduled beginning of
the first Offering Period to be affected thereafter.

      5. PARTICIPATION.

            a. An eligible Employee may become a participant in the Plan by
completing a subscription agreement in the form of Exhibit A authorizing payroll
deductions in a form



provided by the Company's payroll office and filing it with the Company's
payroll office prior to the applicable Enrollment Date.

            b. Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
termination by the participant as provided in Section 10 hereof.

      6. PAYROLL DEDUCTIONS.

            a. At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period.

            b. All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

            c. A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions to not more than fifteen percent (15%) or less
than zero percent (0%) not more than two (2) times during each Offering Period
by completing or filing with the Company a new subscription agreement
authorizing such change in payroll deduction rate. The Board may, in its
discretion, increase or decrease the number of participation rate changes during
any Offering Period. The change in rate shall be effective with the first full
payroll period following the fifth (5th) business day after the Company's
receipt of the new subscription agreement unless the Company elects to process a
given change in participation more quickly. A participant's subscription
agreement shall remain in effect for successive Offering Periods unless
terminated as provided in Section 10 hereof (i.e., unless a participant notifies
the Company that he or she wishes to discontinue participation in the Plan as of
the end of an Offering Period, the participant will automatically be re-enrolled
in the next Offering Period).

            d. At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the participant.

      7. GRANT OF OPTION. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase (at the applicable Purchase Price) up to a whole number of
shares of the Company's Common Stock determined by dividing $12, 500 by the Fair
Market Value of a share of Common Stock on the



Enrollment Date (subject to any adjustment pursuant to Section 19), and provided
that such purchase shall be subject to the limitations set forth in Section 3(b)
and 13 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has withdrawn pursuant to Section 10 hereof. The
option shall expire on the last day of the Offering Period.

      8. EXERCISE OF OPTION. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option which have vested on such Exercise Date shall be
purchased for such participant at the applicable Purchase Price with the
accumulated payroll deductions in his or her account. No fractional shares shall
be purchased. Any money left over in a participant's account after the last
trading day of each purchase period will be returned to the participant. During
a participant's lifetime, a participant's option to purchase shares hereunder is
exercisable only by him or her.

      9. DELIVERY. As promptly as practicable after each Exercise Date on which
a purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate or account credit book entry with
a brokerage firm representing the shares purchased upon exercise of his or her
option.

      10. WITHDRAWAL.

            a. A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by delivering written notice to the
Company in the form of Exhibit B to this Plan at least ten business days in
advance of the next Exercise Date. A notice of withdrawal that is received by
the Company fewer than ten business days in advance of the next Exercise Date
shall not be effective for the ongoing Offering Period. Promptly after the
notice of withdrawal becomes effective, all of the participant's payroll
deductions credited to his or her account shall be paid to such participant and
such participant's option for the Offering Period shall be automatically
terminated, and no further payroll deductions for the purchase of shares shall
be made for such Offering Period. If a participant withdraws from an Offering
Period, payroll deductions shall not resume at the beginning of the succeeding
Offering Period unless the participant delivers to the Company a new
subscription agreement.

            b. A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

      11. TERMINATION OF EMPLOYMENT. Upon a participant's ceasing to be an
Employee, for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of



employment during the period in which the participant is subject to such payment
in lieu of notice.

      12. INTEREST. No interest shall accrue on the payroll deductions of a
participant in the Plan.

      13. STOCK.

            a. Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, on each Enrollment Date, commencing on
June 1, 2002 through and including October 28, 2009 (or termination of the Plan,
if earlier), the number of shares of the Company's Common stock which shall be
made available for sale under the Plan shall be automatically increased by the
number of shares of Common Stock necessary to cause the number of shares then
available for sale to be restored to 1,500,000, subject to adjustment under
Section 19 hereof. No such increase shall cause the aggregate number of shares
of Common Stock made available for sale under the Plan to exceed 20,000,000
shares, subject to adjustment under Section 19 hereof. If, on a given Exercise
Date, the number of shares with respect to which options are to be exercised
exceeds the number of shares then available under the Plan, the Company shall
make a pro rata allocation of the shares remaining available for purchase in as
uniform a manner as shall be practicable and as it shall determine to be
equitable.

            b. The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

            c. Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

      14. ADMINISTRATION. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

      15. DESIGNATION OF BENEFICIARY.

            a. A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option. If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

            b. Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death,



the Company shall deliver such shares and/or cash to the executor or
administrator of the estate of the participant, or if no such executor or
administrator has been appointed (to the knowledge of the Company), the Company,
in its discretion, may deliver such shares and/or cash to the spouse or to any
one or more dependents or relatives of the participant, or if no spouse,
dependent or relative is known to the Company, then to such other person as the
Company may designate.

      16. TRANSFERABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

      17. USE OF FUNDS. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

      18. REPORTS. Individual accounts shall be maintained for each participant
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

      19. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, LIQUIDATION,
MERGER OR ASSET SALE.

            a. Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Offering Period (pursuant to Section 7), as well
as the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

            b. Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the



Board. The New Exercise Date shall be before the date of the Company's proposed
dissolution or liquidation. The Board shall notify each participant in writing,
at least ten (10) business days prior to the New Exercise Date, that the
Exercise Date for the participant's option has been changed to the New Exercise
Date and that the participant's option shall be exercised automatically on the
New Exercise Date, unless prior to such date the participant has withdrawn from
the Offering Period as provided in Section 10 hereof.

            c. Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a New Exercise Date (the "New
Exercise Date") and the Offering Period then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

      20. AMENDMENT OR TERMINATION.

            a. The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 19 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders. Except as provided in Section 19
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any
other applicable law, regulation or stock exchange rule), the Company shall
obtain stockholder approval in such a manner and to such a degree as required.

            b. Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.



      21. NOTICES. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

      22. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

      As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

      23. TERM OF PLAN. The plan became effective on October 28, 1999, the date
the Company's initial public offering of its equity securities registered on
Form S-1 was declared effective by the Securities and Exchange Commission. It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 20 hereof. The effective date of this Amended and Restated Plan is
June 1, 2005.
