 Exhibit 10.15 
 AKAMAI TECHNOLOGIES, INC. 
 Performance Share Restricted Stock Unit Agreement  
 Granted Under the 2006 Stock Incentive Plan 
 1. Grant of Award. 
 This Agreement evidences the grant by Akamai Technologies, Inc., a Delaware corporation (the
“Company”) on                     , 2009 (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 Company’s 2006 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 minimum number of shares issuable is zero; the
maximum number of shares issuable is equal to 50% of the number of shares granted under the terms of the other Restricted Stock Unit Agreement entered into by the Participant and Employee on the Grant Date (the number of RSUs from which such shares
would derive, the “Maximum RSU Bonus Award”). 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. 
 2. Vesting; Forfeiture. 
 (a) Subject to the terms and conditions of this Agreement including, without limitation, Paragraph 2(c) below, this award shall vest on the 2011 Reporting
Date if, and to the extent that, the Company achieves the financial performance criteria set forth in Schedule 1 to this Agreement. Such date or any other date on which shares vest under this Agreement may be referred to herein as a
“Vesting Date.” 
 (b) The “2011 Reporting Date” shall mean the date on which the Company files its annual Public Company
Financial Statements for fiscal year 2011 or completes its annual Private Company Financial Statements for fiscal year 2011, as applicable. If, on December 31, 2011, the Company is required to make periodic reports under the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), the Company’s consolidated financial statements filed with the Securities and Exchange Commission on Form 10-K shall constitute its “Public Company Financial Statements” and
shall apply. If, on December 31, 2011, the Company is not required to make periodic reports under the Exchange Act, the Company’s regularly prepared annual audited financial statements prepared by management shall be its “Private
Company Financial Statements” and shall apply. The applicable financial statements may be referred to herein as the “2011 Financial Statements.” 
 (c) 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. For purposes of this Agreement, employment with the Company shall include employment with a parent, subsidiary, affiliate or division of the Company. 
 (d) If the Participant dies or becomes disabled on or after January 1, 2012 but before the 2011 Reporting Date, he or she shall be deemed to have
been employed as of the 2011 Reporting Date. 







 3. Distribution of Shares. 
 (a) The Company will distribute to the Participant (or to the Participant’s estate in the event that his or her death occurs on or after
January 1, 2012) the Shares of Common Stock represented by vested RSUs as follows: within 30 days of the Vesting Date; provided that if the Participant vests as the result of the application of Section 2(d), the earlier of 30 days after
the 2011 Reporting Date or March 15, 2012. 
 (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. 
 4. Restrictions on Transfer. 
 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. 
 5. Dividend and Other Shareholder Rights. 
 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. 
 6. Provisions of the Plan; Acquisition Event or Change in Control Event. 
 (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), 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), vesting of each RSU shall be determined in accordance with the provisions of Schedule 1 to this Agreement. 
 7.
Withholding Taxes. 
 (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 

  

 - 2 - 








 
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 on
compliance by the Participant with this Section 7. In this regard, the Participant authorizes the Company and/or the Employer to withhold all applicable Tax-Related Items legally payable by the Participant from his or her wages or other cash
compensation paid to the Participant by the Company and/or the Employer. Alternatively, or in addition, if permissible under local law, the Company may withhold in shares of Common Stock an amount of shares sufficient to cover the Participant’s
tax liability. 
 (c) The Participant will pay to the Company or the Employer any amount of Tax-Related Items that the Company or the
Employer may be required to withhold as a result of the Participant’s participation in the Plan or the Participant’s award that cannot be satisfied by the means previously described. 
 (d) As a condition to receiving any Shares, on the date of this Agreement, Participant must execute the Irrevocable Standing Order to Sell Shares
attached hereto, which authorizes the Company and Charles Schwab & Co., Inc. (or such substitute brokerage firm as is contracted to manage the Company’s employee equity award program, the “Broker”) to take the actions
described in Section 7(b) and this Section 7(d) (the “Standing Order”). 
 (e) Participant understands and agrees that
the number of Shares that the Broker will sell will be based on the closing price of the Common Stock on the last trading day before the applicable Vesting Date. The Participant agrees to execute and deliver such documents, instruments and
certificates as may reasonably be required in connection with the sale of the Shares pursuant to this Section 7. 
 (f) Participant
agrees that the proceeds received from the sale of Shares pursuant to Section 7(d) will be used to satisfy the Tax-Related Items and, accordingly, Participant hereby authorizes the Broker to pay such proceeds to the Company for such purpose.
Participant understands that to the extent that the proceeds obtained by such sale exceed the amount necessary to satisfy the Tax-Related Items, such excess proceeds shall be deposited into the Participants account with Broker. Participant further
understands that any remaining Shares shall be deposited into such account. 
 (g) The Participant represents to the Company that, as of the
date hereof, he is not aware of any material nonpublic information about the Company or the Common Stock. The Participant and the Company have structured this Agreement to constitute a “binding contract” relating to the sale of Common
Stock pursuant to this Section 7, consistent with the affirmative defense to liability under Section 10(b) of the Securities Exchange Act of 1934 under Rule 10b5-1(c) promulgated under such Act. 
 8. Miscellaneous. 
 (a) No Rights
to Employment. The Participant acknowledges and agrees that the vesting of the RSUs pursuant to Section 2 hereof is earned only by continuing service as an employee at the will of the Company (not through the act of being hired or
purchasing shares hereunder). The Participant further acknowledges and agrees that the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of continued engagement as an
employee or consultant for the vesting period, for any period, or at all.

instance, by the Board of Directors of the Company.

benefit of the Company and the Participant and their respective heirs, executors, administrators, legal representatives, successors and assigns, subject to the restrictions on transfer set forth in Section 4 of this Agreement.

deposit in the United States Post Office, by registered or certified mail, postage prepaid, addressed to the other party hereto at the address shown beneath his or its respective signature to this Agreement, or at such other address or addresses as
either party shall designate to the other in accordance with this Section 8(e). 
 (f) Pronouns. Whenever the context may
require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. 
 (g) Entire Agreement; Conflicts and Interpretation. This Agreement and the Plan constitute the entire agreement between the parties and supersede
all prior agreements and understandings relating to the subject matter of this Agreement. In the event of any conflict between this Agreement and the Plan, the Plan shall control. In the event of any ambiguity in this Agreement, or any matters as to

(ii) prescribe, amend and rescind rules and regulations relating to the Plan and (iii) make all other determinations deemed necessary or advisable for the administration of the Plan. 
 (h) Amendment. The Company may modify, amend or waive the terms of this prospectively or retroactively, but no such modification, amendment or
waiver shall impair the rights of the Participant without his or her consent, except as required by applicable law, NASDAQ or stock exchange rules, tax rules or accounting rules. Any provision for the benefit of the Company contained in this
Agreement may be waived, either generally or in any particular instance, by the Board of Directors (or a committee thereof) of the Company. The waiver by either party of compliance with any provision of this Agreement shall not operate or be
construed as a waiver of any other provision of this Agreement, or of any subsequent breach by such party of a provision of this Agreement.

 IRREVOCABLE STANDING ORDER TO SELL SHARES 
 The Participant has been granted restricted stock units (“RSUs”) by Akamai Technologies, Inc. (“Akamai”), which is evidenced by a
restricted stock unit agreement between me and Akamai (the “Agreement,” copy attached). Provided that I remain employed by Akamai on each vesting date, the shares vest according to the provisions of the Agreement. 
 I understand that on each vesting date, the shares issuable in respect of vested RSUs (the “Shares”) will be deposited into my account at
Charles Schwab & Co., Inc. (“Schwab”) and that I will recognize taxable ordinary income as a result. Pursuant to the terms of the Agreement and as a condition of my receipt of the Shares, I understand and agree that, for each
vesting date, I must sell a number of shares sufficient to satisfy all withholding taxes applicable to that ordinary income. Therefore, I hereby direct Schwab to sell, at the market price and on each vesting date listed above (or the first
business day thereafter if a vesting date should fall on a day when the market is closed) or as soon as practicable thereafter, the number of Shares that Akamai informs Schwab is sufficient to satisfy the applicable withholding taxes, which shall be
calculated based on the closing price of Akamai’s common stock on the last trading day before each vesting date. I understand that Schwab will remit the proceeds to Akamai for payment of the withholding taxes. 
 I hereby agree to indemnify and hold Schwab harmless from and against all losses, liabilities, damages, claims and expenses, including reasonable
attorneys’ fees and court costs, arising out of any (i) negligent act, omission or willful misconduct by Akamai in carrying out actions pursuant to the third sentence of the preceding paragraph and (ii) any action taken or omitted by
Schwab in good faith reliance upon instructions herein or upon instructions or information transmitted to Schwab by Akamai pursuant to the third sentence of the preceding paragraph. 
 I understand and agree that by signing below or effecting an online acceptance of the Agreement, I am making an Irrevocable Standing Order to Sell Shares
which will remain in effect until all of the shares have vested. I also agree that this Irrevocable Standing Order to Sell Shares is in addition to and subject to the terms and conditions of any existing Account Agreement that I have with Schwab.

 SCHEDULE 1 
 VESTING CRITERIA FOR RSUs 
 A. Overview 
 The RSUs shall vest only upon the Company’s achievement of certain financial metrics based on target cumulative Revenue of $            million and
target cumulative Normalized EPS of $            per share over the Company’s fiscal years 2009, 2010 and 2011. The Company’s performance measured against each metric shall be
equally weighted to enable comparison as a percentage of a combined target. For purposes of this Agreement, such metrics shall have the following meanings: 
 “Revenue” shall mean the Company’s cumulative annual revenue for fiscal years 2009, 2010 and 2011 calculated in accordance with generally accepted accounting principles in the United States of America
as reported in the 2011 Financial Statements. 
 “Normalized EPS” shall mean the Company’s shall mean the Company’s
cumulative annual earnings per diluted share for fiscal years 2009, 2010 and 2011 excluding cumulative amortization of intangible assets, equity-related compensation, restructuring charges and benefits, certain gains and losses on equity
investments, non-cash income taxes and loss on early extinguishment of debt. 
 “Vesting Amount” shall mean the aggregate amount,
if any, issuable to the Participant based on the Company’s Revenue and Normalized EPS performance measured against the Actual Percentage of Targets defined below. 
 B. Calculation of Percentages 
 The Company’s Revenue shall be calculated as a percentage of the
Company’s target cumulative revenue for fiscal years 2009, 2010 and 2011of $            million and multiplied by 0.5 (the “Revenue Percentage Component”). The Company’s
Normalized EPS shall be calculated as a percentage of the Company’s target cumulative normalized earnings per share, calculated in accordance with generally accepted accounting principles in the United States of America, as reported in the 2011
Financial Statements for fiscal years 2009, 2010 and 2011 of $            and multiplied by 0.5 (the “Normalized EPS Component”). The sum of the Revenue Percentage Component and
the Normalized EPS Component shall be the “Actual Percentage of Targets.” 
 C. Vesting Amounts 
 1. If the Actual Percentage of Targets fails to exceed 100%, then none of the RSUs shall vest and zero Shares shall be distributed in respect thereof.

 2. If the Actual Percentage of Targets equals             %, then the Vesting
Amount shall equal one-half of the Maximum RSU Bonus Award, as defined in Paragraph 1 of the Agreement (the “Intermediate RSU Bonus Award”), and shall vest. 
 3. If the Actual Percentage of Targets equals             % or more, then the Vesting Amount shall equal the Maximum RSU Bonus Award, as defined in Paragraph
1 of the Agreement, and shall vest. 
 4. If the Actual Percentage of Targets is between 100% and
            %, then the Vesting Amount shall equal a number of RSUs equal to the product of the Intermediate RSU Bonus Award multiplied by a fraction the numerator of which is the Actual
Percentage of Targets Revenue minus 100% and the denominator is             % and shall vest. 
  

 - 8 - 








 5. If the Actual Percentage of Targets is between
            % and             %, then the Vesting Amount shall equal the sum of (a) the Intermediate RSU Bonus Award plus
(b) the product of (i) the difference between the Maximum RSU Bonus Award and the Intermediate RSU Bonus Award multiplied by (ii) a fraction the numerator of which is the Actual Percentage of Targets Revenue minus 103% and the
denominator is 4%, and shall vest. 
 D. Effect of an Acquisition by the Company 
 In the event that the Company enters into an Acquisition Transaction during 2009, then Revenue and Normalized EPS shall be adjusted to give effect to such
Acquisition Transaction. An “Acquisition Transaction” means (i) the purchase by the Company of more than 50% of the voting power of another entity, (ii) any merger, reorganization, consolidation, recapitalization, business
combination, liquidation, dissolution or share exchange which results in the Company acquiring more than 50% of the voting power of another entity, or (iii) the purchase or other acquisition (including, without limitation, via license outside
of the ordinary course of business or joint venture) of assets that constitute more than 50% of another entity’s total assets or assets that account for more than 50% of the consolidated net revenues or net income of such entity. 
 As soon as practicable following the closing of an Acquisition Transaction, the Compensation Committee of the Board of Directors of the Company shall
make a determination of the estimated impact of the Acquisition Transaction on the Company’s cumulative Revenue and Normalized EPS through 2011. If the Acquisition Transaction is estimated to be accretive, then: 
 (i) in calculating Revenue for purposes of determining the Revenue Percentage Component, reported Revenue shall be reduced by the amount of estimated
revenue contribution from the Acquisition Transaction; and 
 (ii) in calculating Normalized EPS for purposes of determining the Normalized
EPS Percentage Component, Normalized EPS, as calculated based on the 2011 Financial Statements, shall be reduced by the amount of the estimated Normalized EPS contribution from the Acquisition Transaction. 
 If the Acquisition is estimated to be non-accretive, then: 
 (iii) in calculating Normalized EPS for purposes of determining the Normalized EPS Percentage Component, Normalized EPS, as calculated based on the 2011 Financial Statements, shall be increased by the amount of the estimated negative
Normalized EPS impact from the Acquisition Transaction. 
 All determinations of the Compensation Committee regarding the estimated impact of an Acquisition
Transaction shall be final, binding and non-appealable. This Agreement shall be deemed to be automatically amended, without further action by the Company or the Participant, to give effect to any adjustments required by this Section D. 

E. Effect of a Change in Control Event 
 (1) If
there is a Change of Control Event prior to December 31, 2011, the RSUs shall vest as of the closing date of the Change of Control Event and Participant shall be entitled to receive a pro rated number of Shares based on the amount of time
elapsed between the Grant Date and December 31, 2011. The number of Shares issuable in respect of vested RSUs, if any, shall be calculated based on a pro forma Actual Percentage of Targets calculated as follows: 
 (i) If the Change of Control Event occurs in 2009, Revenue and Normalized EPS shall be calculated based on the Company’s Revenue and Normalized EPS
results during the twelve-month period ending on the last day of the most recently reported fiscal quarter prior to the closing date of the Change of Control Event. Such numbers shall then be multiplied by three for purposes of calculating the
Actual Percentage of Targets. 
  

 - 9 - 








 (ii) If the Change of Control Event occurs in 2010, Revenue and Normalized EPS shall be calculated based
on the Company’s Revenue and Normalized EPS results for fiscal year 2009. Such numbers shall then be multiplied by three for purposes of calculating the Actual Percentage of Targets. 
 (iii) If the Change of Control Event occurs in 2011, Revenue and Normalized EPS shall be calculated based on the cumulative Revenue and Normalized EPS
results for fiscal years 2009 and 2010 plus an amount equal to the Revenue and Normalized EPS for 2011 that would result if the rate of growth (loss) for Revenue and Normalized EPS, respectively, between 2009 and 2010 were to continue for 2011. Such
sums shall be used for calculating the Actual Percentage of Targets. 
 Once the pro forma Actual Percentage of Targets has been determined and the number of
Shares, if any, that would have been issuable in respect of the RSUs on the 2011 Reporting Date (the “Pro Forma Distribution Amount”) calculated, the actual number of Shares issuable shall be adjusted proportionally based on the percentage
of the three-year calculation period that has elapsed as of the closing date of the Change of Control Event (e.g., if the closing date of the Change in Control Event were April 1, 2010, the number of Shares issuable would be 41.7% (15 months/36
months) of the total Pro Forma Distribution Amount). 
 (2) If (i) there is a Change of Control Event between January 1, 2012 and
September 30, 2012; (ii) Participant meets the requirements of Paragraph 2(c) of this Agreement as of immediately prior to the Change of Control Event and (iii) Participant’s employment is terminated by the surviving entity in
the Change of Control transaction at any time during the period between the Change of Control Event and October 1, 2012 for any reason other than for Cause (as defined below), then the entire portion of the Vesting Amount that had not vested
prior to Participation’s termination shall vest in full as of the effective date of Participant’s termination. For purposes of this Agreement, “Cause” shall mean (a) any act or omission by Participant that has an adverse
effect on Akamai’s business or on the employee’s ability to perform services for Akamai, including, without limitation, the commission of any crime (other than ordinary traffic violations), or (b) refusal or failure to perform
assigned duties, serious misconduct, or excessive absenteeism. Whether a Participant has been terminated for “Cause” shall be determined in the sole discretion of the Company’s management or, in the case of an executive officer, the
Board of Directors or a committee thereof.
