Exhibit 10.3

AKAMAI TECHNOLOGIES, INC.

Restricted Stock Unit Agreement

Granted Under the 2009 Stock Incentive Plan

This Agreement evidences the grant by Akamai Technologies, Inc., a Delaware corporation (the “Company”) on                     ,              (the “Grant Date”) to you (the “Participant”) of              restricted stock units of the Company (individually, an “RSU” and collectively, the “RSUs”), subject to the terms and conditions set forth in this Restricted Stock Unit Agreement (the “Agreement”) and the 2009 Stock Incentive Plan (the “Plan”). Each RSU represents the right to receive one share of the common stock, par value $.01 per share, of the Company (“Common Stock”) as provided in this Agreement. The shares of Common Stock that are issuable upon vesting of the RSUs are referred to in this Agreement as “Shares.” Capitalized terms used but not defined in this Agreement shall have the meanings specified in the Plan.

Subject to the terms and conditions of this Agreement and provided that the Participant continues to provide services until the Vesting Date (as defined below):

(a) This award shall vest as to 33% of the original number of RSUs on the first anniversary of the Grant Date and as to an additional 8.375% of the original number of RSUs at the end of each successive full three-month period thereafter; provided, however, that if any of the foregoing dates is not a business day, then vesting shall occur on the next succeeding business day. The date on which RSUs vest may be referred to herein as the “Vesting Date.”

(b) Except as otherwise provided in this Section 2, RSUs shall not continue to vest unless the Participant is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the Company.

(c) In the event that the Participant’s employment with the Company ceases or is terminated for any reason, including by reason of death or disability, other than “Cause” (as defined below), then the number of RSUs which shall be vested shall be the number that are vested as of the date of actual termination. For purposes of this Section 2, “Cause” shall mean unsatisfactory job performance (as determined by the Company), willful misconduct, fraud, gross negligence, disobedience or dishonesty. In the event that the Participant’s employment with the Company is terminated for Cause, all unvested RSUs shall be forfeited effective as of the date of termination.

(d) For purposes of this Agreement, employment with the Company shall include employment with a parent, subsidiary, affiliate or division of the Company.

(a) The Company will distribute to the Participant (or to the Participant’s estate in the event that his or her death occurs after a Vesting Date but before distribution of the corresponding Shares), the Shares of Common Stock represented by RSUs that vested on such vesting date as soon as

administratively practicable after each vesting date (each such date of distribution is hereinafter referred to as a “Settlement Date”) but in any event within the period ending on the later to occur of the date that is two and one-half months from the end of (i) Participant’s tax year that includes the applicable Vesting Date or (ii) the Company’s tax year that includes the applicable Vesting Date.

(b) The Company shall not be obligated to issue to the Participant the Shares upon the vesting of any RSU (or otherwise) unless the issuance and delivery of such Shares shall comply with all relevant provisions of law and other legal requirements including, without limitation, any applicable federal or state securities laws and the requirements of any stock exchange upon which shares of Common Stock may then be listed.

(c) Neither the Company nor the Participant shall have the right to accelerate or defer the deliver of any shares under this Agreement except to the extent specifically permitted under Section 409A of the Internal Revenue Code of 1986, as amended.

The Participant shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise (collectively “transfer”) any RSUs, or any interest therein, except by will or the laws of descent and distribution.

Except as set forth in the Plan, neither the Participant nor any person claiming under or through the Participant shall be, or have any rights or privileges of, a stockholder of the Company in respect of the Shares issuable pursuant to the RSUs granted hereunder until the Shares have been delivered to the Participant.

(a) This Agreement is subject to the provisions of the Plan, a copy of which is made available to the Participant with this Agreement.

(b) Upon the occurrence of an Acquisition Event (as defined in the Plan) that is not a Change in Control Event (as defined in the Plan), each RSU (whether vested or unvested) shall inure to the benefit of the Company’s successor and shall apply to the cash, securities or other property which the Common Stock was converted into or exchanged for pursuant to such Acquisition Event in the same manner and to the same extent as they applied to the Common Stock subject to such RSU.

(c) Upon the occurrence of a Change in Control Event (regardless of whether such event also constitutes an Acquisition Event), each RSU shall become exercisable, realizable or vested as to number of RSUs as would be vested pursuant to Section 2(a) as though the Grant Date were the date that is one year prior to the Grant Date.

(a) Regardless of any action the Company or the Participant’s employer (“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), the Participant acknowledges that the ultimate liability for all Tax-Related Items legally due by him or her is and remains the Participant’s responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Stock Unit award, including the grant and vesting of the Restricted Stock Units, the receipt of cash or any dividends or dividend equivalents; and (2) do not commit to structure the terms of the award or any aspect of the Restricted Stock Units to reduce or eliminate the Participant’s liability for Tax-Related Items.

(b) In the event that the Company, subsidiary, affiliate or division is required to withhold any Tax-Related Items as a result of the award or vesting of the Restricted Stock Units, or the receipt of cash or any dividends or dividend equivalents, the Participant shall pay or make adequate arrangements satisfactory to the Company, subsidiary, affiliate or division to satisfy all withholding and payment on account obligations of the Company, subsidiary, affiliate or division. The obligations of the Company under this Agreement, including the delivery of shares upon vesting, shall be conditioned
