Lisa Arthur
[address]


Dear Lisa:

On behalf of Akamai Technologies, Inc. (referred to in this letter collectively
with its subsidiaries as the "Company"), I am pleased to confirm the offer of
full-time employment with the Company that Tiffany Mosher-Taylor made to you for
the position of Vice President, Global Marketing and Chief Marketing Officer in
our Cambridge office. You will report to George Conrades in this capacity
starting on June 28, 2004. This offer is contingent upon the following: (1)
completion of an employment application, which is enclosed with this letter; (2)
successful completion of a check of your business references; (3) your consent
to and the successful completion of a background investigation conducted
pursuant to the Company's standard procedures.

Your base salary will be $9,615.38 bi-weekly ($250,000.00 on an annualized
basis). You will be eligible to receive an annual incentive bonus, based on
performance against objectives set by your manager, of up to 20% of your base
salary. Your compensation shall be subject to review annually.

In your first year of employment as Vice President, Global Marketing and Chief
Marketing Officer, you will be eligible to earn a maximum one-time bonus of
$30,500.00, less withholding taxes, to cover your Oracle stock option buy-out
and relocation expenses to Cambridge. The bonus will be paid out in two
installments, with half being paid in the first payroll, and half being paid in
the first payroll after six months from your start date on the condition that
you are performing your duties to the satisfaction of the Company. In the event
that you leave the employ of the Company voluntarily or leave the Vice President
Global Marketing and Chief Marketing Officer role voluntarily before one or both
of the bonus installments have been earned, no further payments will be made. If
you leave the Company or role voluntarily within one year, you will be required
to return the bonus payments on a prorated basis.

As part of this employment offer, the Company will recommend to the Akamai Board
of Directors that you be granted a stock option under the Company's 1998 Stock
Incentive Plan (the Plan) for the purchase of an aggregate of 75,000 shares of
Common Stock of the Company, at an option price equal to the fair market value
of the Common Stock as determined by the Board on the date the Board of
Directors approves your stock option. If approved, your stock options at Akamai
will vest over four years, provided you remain employed, all on a schedule
beginning on the date your options are granted. The first 25 percent of the
options will vest on the first anniversary of your Grant Date. An additional
6.25% of the original number of shares will vest

at the end of each successive full three-month period following the first
anniversary of the Grant Date until the fourth anniversary of the Grant Date.
Subject to Board approval, your options will be evidenced by a separate option
agreement embodying these terms. You will also be eligible to receive such
future stock option grants, as the Board of Directors shall from time to time
deem appropriate.

You will be eligible to participate in the Employee Stock Purchase Program
beginning in the December 2004 offering period. This plan allows you to
contribute between 1% and 15% of your salary through regular payroll deductions.
The Akamai plan provides for a two-year offering period, that includes four,
six-month purchase periods. At the end of each six-month purchase period, the
money that has been deducted will be used to purchase shares of Akamai common
stock at 85% of the closing price of the Common Stock at the beginning of the
offer period or end of the purchase period, whichever is lower.


You will be eligible to elect health insurance, dental insurance, life
insurance, and short/long term disability coverage and other benefits that are
and may become available generally to employees of the Company. Coverage takes
effect the first of the month following date of hire. You will also be eligible
to contribute to the Akamai Technologies, Inc. 401(k) Plan immediately upon
employment.

You will be eligible for a maximum of three weeks of vacation per year. The
number of vacation days for which you are eligible in each year shall accrue at
the rate of 1.25 days per month that you are employed and working during such
year. Akamai also observes eleven holidays each year. This year nine of the
holidays are scheduled days, while two holidays are floating days.

Prior to the commencement of your employment, you will be required to execute a
Non-Competition, Non-Solicitation, Proprietary and Confidential Information and
Developments Agreement. Execution of this agreement is a condition of
employment.

You represent that you are not bound by any employment contract, restrictive
covenant or other restriction preventing you from entering into this agreement
or carrying out your responsibilities for the Company as contemplated hereby, or
which is in any way inconsistent with any of the terms hereof.

Akamai Technologies is an at will employer which means that either you or Akamai
may terminate the employment relationship at any time with or without notice and
with or without reason. This letter is not to be construed as an agreement,
either expressed or implied to employ you for any stated term. No employee,
officer or other representative of Akamai, other than the Chief Executive
Officer, has any authority to enter into any agreement to the contrary.

This employment offer from Akamai Technologies is contingent upon your

PROOF OF YOUR EMPLOYABILITY IN THE UNITED
