AKAMAI TECHNOLOGIES, INC.

2009 STOCK INCENTIVE PLAN

The purpose of this 2009 Stock Incentive Plan (the “Plan”) of Akamai Technologies, Inc., a Delaware corporation (the “Company” or “Akamai”), is to advance the interests of the Company’s stockholders by enhancing the Company’s ability to attract, retain and motivate persons who are expected to make important contributions to the Company and by providing such persons with equity ownership opportunities and performance-based incentives that are intended to align their interests with those of the Company’s stockholders. Except where the context otherwise requires, the term “Company” shall include any of the Company’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”) and any other business venture (including, without limitation, joint venture or limited liability company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the “Board”).

Except as otherwise provided in Section 5(b), all of the Company’s employees, officers, directors, consultants and advisors are eligible to receive options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards (each, an “Award”) under the Plan. Each person who receives an Award under the Plan is deemed a “Participant”.

(a) Administration by Board of Directors . The Plan will be administered by the Board. Subject to and consistent with the provisions of the Plan, the Board shall have the authority and discretion to: (i) determine which eligible employees, officers, directors, consultants and advisors will receive Awards, (ii) determine the number of shares of Common Stock (as hereinafter defined), cash, or other consideration to be covered by each Award, (iii) determine the terms and conditions of any Award (including Fair Market Value (as hereinafter defined), the exercise price, the vesting schedule, the term of the Award, and the period following termination from employment or service during which an Award may be exercised), (iv) approve forms of Award agreements and other documentation for use under the Plan, (v) adopt, alter, and repeal administrative rules, guidelines, and practices governing the operation of the Plan, (vi) interpret the provisions of the Plan and any Award documentation and remedy any ambiguities, omissions, or inconsistencies therein, (vii) modify or amend Awards, or grant waivers of Plan or Award conditions, (viii) determine the nature and provisions of Other Stock Unit Awards (as hereinafter defined) permitted pursuant to Section 8, and (ix) make all other determinations necessary or advisable for the administration of the Plan. All decisions by the Board shall be made in the Board’s sole discretion and shall be final and binding on all persons having or claiming any interest in the Plan or in any Award. No director or person acting pursuant to the authority delegated by the Board shall be liable for any action or determination relating to or under the Plan made in good faith.

(b) Appointment of Committees . To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (a “Committee”). All references in the Plan to the “Board” shall mean the Board or a Committee of the Board or the officers referred to in Section 3(c) to the extent that the Board’s powers or authority under the Plan have been delegated to such Committee or officers. Notwithstanding the foregoing, for purposes of granting Awards to directors, the Committee shall mean the Compensation Committee.

(c) Delegation to Officers . To the extent permitted by applicable law, the Board may delegate to one or more officers of the Company the power to grant Awards to employees or officers of the Company or any of its present or future subsidiary corporations and to exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the terms of the Awards to be granted by such officers (including the exercise price of such Awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to Awards that the officers may grant; provided further, however, that no officer shall be authorized to grant Awards to any “executive officer” of the Company (as defined by Rule 3b-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act).

(d) Awards to Non-Employee Directors . Awards to non-employee directors will only be granted and administered by a Committee, all of the members of which are independent as defined by Section 4200(a)(15) of the Nasdaq Marketplace Rules.

(a) Number of Shares . Subject to adjustment under Section 9, Awards may be made under the Plan for up to 8,500,000 shares of common stock, $0.01 par value per share, of the Company (the “Common Stock”). Subject to adjustment under Section 9, up to 8,500,000 shares of Common Stock may be issued upon exercise of Incentive Stock Options (as hereinafter defined) granted under the Plan. If any Award granted under this Plan or any stock award granted under the Company’s Second Amended and Restated 1998 Stock Incentive Plan, 2001 Stock Incentive Plan or 2006 Stock Incentive Plan (together, the “Existing Plans”) expires or is terminated, surrendered or canceled without having been fully exercised, is forfeited in whole or in part, is settled in cash or otherwise, or results in any Common Stock not being issued, the unused Common Stock covered by such Award or any award issued under the Existing Plans shall revert or again be available for the grant of Awards under the Plan. Notwithstanding any other provision in this Section 4(a), any shares not issued or delivered as a result of the net settlement of any outstanding Stock Appreciation Right, any shares tendered in payment of an Option’s exercise price (whether by attestation or actual delivery), any shares tendered or withheld to satisfy a tax withholding on an Award, and any shares repurchased by the Company using Option proceeds shall not revert or again be available for the grant of Awards under the Plan. In the case of Incentive Stock Options (as hereinafter defined), the foregoing provisions shall be subject to any limitations under the Code. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares, treasury shares or shares purchased on the open market.

(b) Sub-limits . Subject to adjustment under Section 9, the following sub-limits on the number of shares subject to Awards shall apply:

(1) Section 162(m) Per-Participant Limit . The maximum number of shares of Common Stock with respect to which Awards may be granted to any Participant under the Plan shall be 1,000,000 per calendar year. For purposes of the foregoing limit, the combination of an Option in tandem with an SAR (as each is hereafter defined) shall be treated as a single Award. The per-Participant limit described in this Section 4(b)(1) shall be construed and applied consistently with Section 162(m) of the Code or any successor provision thereto, and the regulations thereunder (“Section 162(m)”).

(2) Limit on Awards other than Options and SARS . The maximum number of shares with respect to which Awards other than Options and SARs may be granted shall be 90% of the total number of shares available for issuance under the Plan.

(3) Limit on Awards to Directors . The maximum aggregate number of shares with respect to which Awards may be granted to directors who are not employees of the Company at the time of grant shall be 10% of the total number of shares available for issuance under the Plan.

(c) Substitute Awards . In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Awards in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Awards may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Awards contained in the Plan. Substitute Awards shall not count against the overall share limit set forth in Section 4(a), except as may be required by reason of Section 422 and related provisions of the Code.

5. Stock Options

(a) General . The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option, including conditions relating to applicable federal or state securities laws, as it considers necessary or advisable. An Option that is not intended to be an Incentive Stock Option (as hereinafter defined) shall be designated a “Nonstatutory Stock Option”.

(b) Incentive Stock Options . An Option that the Board intends to be an “incentive stock option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall only be granted to employees of Akamai, any of Akamai’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code, and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. If the Fair Market Value (as defined below) of shares on the date of grant with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year exceeds $100,000, the Options for the first $100,000 worth of shares to become exercisable in that calendar year will be Incentive Stock Options, and the Options for the shares with a Fair Market Value (as defined below) in excess of $100,000 that become exercisable in that calendar year will be Nonstatutory Stock Options. The Company shall have no liability to a Participant, or any other party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or for any action taken by the Board, including without limitation the conversion of an Incentive Stock Option to a Nonstatutory Stock Option.

(c) Exercise Price . The Board shall establish the exercise price of each Option and specify such exercise price in the applicable option agreement; provided however, that the exercise price shall not be less than 100% of the Fair Market Value (as defined below) on the date the Option is granted, provided that if the Board approves the grant of an Option with an exercise price to be determined on a future date, the exercise price shall be not less than 100% of the Fair Market Value on such future date.

(d) No Repricing of Options .   Notwithstanding anything to the contrary in the Plan, the Company shall not engage in any repricing of Options or SARs granted under this Plan without further stockholder approval. For this purpose, the term “repricing” shall mean any of the following or other action that has the same effect: (i) lowering the exercise price of an Option or a SAR after it is granted, (ii) any other action that is treated as a repricing under generally accepted accounting principles, or (iii) canceling an Option or a SAR at a time when its exercise price exceeds the fair market value of the underlying stock in exchange for another Option, SAR, Restricted Stock, or other equity of the Company, unless the cancellation and exchange occurs in connection with a merger, acquisition, spin-off, or similar corporate transaction (including any adjustment described in Section 9).

(e) Duration of Options . Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable option agreement; provided however, that no Option will be granted for a term in excess of 7 years.

(f) Exercise of Option . Options may be exercised by delivery to the Company of a written notice of exercise signed by the proper person or by any other form of notice (including electronic notice) approved by the Board together with payment in full as specified in Section 5(g) for the number of shares for which the Option is exercised. Shares of Common Stock subject to the Option will be delivered by the Company following exercise either as soon as practicable or, subject to such conditions as the Board shall specify, on a deferred basis (with the Company’s obligation to be evidenced by an instrument providing for future delivery of the deferred shares at the time or times specified by the Board).

(g) Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:

(1) in cash or by check, payable to the order of the Company;

(2) except as may otherwise be provided in the applicable option agreement, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding;

(3) to the extent provided for in the applicable option agreement or approved by the Board, in its sole discretion, by delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at their fair market value as determined by (or in a manner approved by) the Board (“Fair Market Value”) provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if any, as may be established by the Board in its discretion and (iii) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements;

(4) to the extent permitted by applicable law and provided for in the applicable option agreement or approved by the Board in its sole discretion, by (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful consideration as the Board may determine;

(5) to the extent permitted by applicable law and provided for in the applicable option agreement or approved by the Board in its sole discretion, by retaining shares of Common Stock otherwise issuable pursuant to the Option;

(6) by any combination of the above permitted forms of payment.

(h) No Reload Rights . No option granted under the Plan shall contain any provision entitling the grantee to the automatic grant of additional Options in connection with any exercise of the original Option.

(a) General . The Board may grant Awards consisting of a Stock Appreciation Right, “SAR”, entitling the holder, upon exercise, to receive an amount in Common Stock determined by reference to appreciation, from and after the date of grant, in the fair market value of a share of Common Stock. The date as of which such appreciation or other measure is determined shall be the exercise date.

(b) Grants . Stock Appreciation Rights may be granted in tandem with, or independently of, Options granted under the Plan.

(1) Tandem Awards. When Stock Appreciation Rights are expressly granted in tandem with Options, (i) the Stock Appreciation Right will be exercisable only at such time or times, and to the extent, that the related Option is exercisable (except to the extent designated by the Board in connection with an Acquisition Event or Change in Control Event) and will be exercisable in accordance with the procedure required for exercise of the related Option; (ii) the Stock Appreciation Right will terminate and no longer be exercisable upon the termination or exercise of the related Option, except to the extent designated by the Board in connection with an Acquisition Event or Change in Control Event and except that a Stock Appreciation Right granted with respect to less than the full number of shares covered by an Option will not be reduced until the number of shares as to which the related Option has been exercised or has terminated exceeds the number of shares not covered by the Stock Appreciation Right; (iii) the Option will terminate and no longer be exercisable upon the exercise of the related Stock Appreciation Right; and (iv) the Stock Appreciation Right will be transferable only with the related Option.

(2) Independent SARs. A Stock Appreciation Right not expressly granted in tandem with an Option will become exercisable at such time or times, and on such conditions, as the Board may specify in the SAR Award.

(c) Grant Price . The grant price or exercise price of a SAR shall not be less than 100% of the Fair Market Value per share of Common Stock on the date of grant of the SAR.

(d) Term . The term of a SAR shall not be more than 7 years from the date of grant.

(e) Exercise . Stock Appreciation Rights may be exercised by delivery to the Company of a written notice of exercise signed by the proper person or by any other form of notice (including electronic notice) approved by the Board, together with any other documents required by the Board.

(a) General . The Board may grant Awards entitling recipients to acquire shares of Common Stock (“Restricted Stock”), subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from the recipient in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award. Instead of granting Awards for Restricted Stock, the Board may grant Awards entitling the recipient to receive shares of Common Stock to be delivered at the time such shares of Common Stock vest (“Restricted Stock Units” or “Deferred Stock Units”). (Restricted Stock, Restricted Stock Units and Deferred Stock Units are each referred to herein as a “Restricted Stock Award”.)

(b) Terms and Conditions for all Restricted Stock Awards . The Board shall determine the terms and conditions of a Restricted Stock Award, including the conditions for vesting and repurchase (or forfeiture) and the issue price, if any.

(c) Additional Provisions Relating to Restricted Stock .

(1) Dividends . Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such shares, unless otherwise provided by the Board. If any such dividends or distributions are paid in shares, or consist of a

dividend or distribution to holders of Common Stock other than an ordinary cash dividend, the shares, cash or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were paid. Each dividend payment will be made no later than the end of the calendar year in which the dividends are paid to shareholders of that class of stock or, if later, the 15th day of the third month following the date the dividends are paid to shareholders of that class of stock.

(2) Stock Certificates . The Company may require that any stock certificates issued in respect of shares of Restricted Stock shall be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). At the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or if the Participant has died, to the beneficiary designated, in a manner determined by the Board, by a Participant to receive amounts due or exercise rights of the Participant in the event of the Participant’s death (the “Designated Beneficiary”). In the absence of an effective designation by a Participant, “Designated Beneficiary” shall mean the Participant’s estate.

(d) Additional Provisions Relating to Deferred Stock Units and Restricted Stock Units.

(1) Settlement . Upon the vesting of and/or lapsing of any other restrictions (i.e., settlement) with respect to each Restricted Stock Unit or Deferred Stock Unit, the Participant shall be entitled to receive from the Company one share of Common Stock or an amount of cash equal to the Fair Market Value of one share of Common Stock, as provided in the applicable Award agreement. The Board may, in its discretion, provide that settlement of Restricted Stock Units and Deferred Stock Units shall be deferred, on a mandatory basis or at the election of the Participant in a manner that complies with Code Section 409A.

(2) Voting Rights . A Participant shall
