                                 January 4, 2005

Mr. Paul Sagan
[address]

      Re: Employment Agreement

Dear Paul:

      On behalf of Akamai Technologies, Inc. (the "Company"), this letter sets
forth the terms of your full-time employment as Chief Executive Officer ("CEO")
and President effective April 1, 2005 ("Offer Letter ").

1. Title and Duties.

      Beginning April 1, 2005, you shall serve as CEO and President of the
Company and shall have all powers and duties consistent with this position,
reporting to and subject to the direction and control of the Company's Executive
Chairman of the Board ("Executive Chair") and the Board of Directors ("Board").
You shall perform such other duties and responsibilities on behalf of the
Company as may reasonably be assigned from time to time by the Executive Chair
and/or Board consistent with the position of CEO and President. In no way
limiting the foregoing, you will be responsible for the management and
operational success of the Company, including responsibility for the Company's
operating results, particularly its quarterly and financial objectives,
efficiency and effectiveness of the Company's management and business planning
process, positioning the Company to achieve its goals for profitable growth, and
compliance with applicable laws and regulatory requirements.

      You will lead the development and implementation of Akamai's strategic
plan; monitor continuous improvement in the Platform and in the effectiveness of
Marketing and Sales/Services, while ensuring the effective interrelationship
among Platform, Product Management and Sales/Services; oversee the strengthening
of the Company's internal controls over financial reporting and disclosure
controls and procedures; the effective implementation of personnel leadership
development, succession planning, and other Human Resources initiatives; and
oversee the Company's major litigation and any M&A activities.

      Your direct reports initially will include all members of the Office of
the CEO, including the Chief Financial Officer, Executive Vice President of
Sales and Services, Executive Vice President of Platform, Chief Marketing
Officer, Chief Scientist, Chief Technology Officer, General Counsel, Vice
President of Human Resources, and Senior Director of Business Development. You
also shall be a frequent public representative of the Company to investors, and
prospective and existing customers and partners.
<PAGE>
2. Base Salary.

      Effective January 4, 2005, your base salary shall be at the annualized
rate of $400,000 per year ($33,333 per month). Your salary shall be subject to
review annually by the Compensation Committee after consideration of an
assessment of your performance by the Nominating and Governance Committee and
recommendations by the Executive Chair.

3. Incentive Bonus.

      You will be eligible for an incentive bonus in any year that the Company
provides an incentive bonus plan for the senior executive team. If the Board
approves a senior executive bonus plan for fiscal year 2005, you will be
eligible for an incentive bonus award up to 100% of your annualized base salary.
The bonus award, if any, will be based on achievement of the individual and
corporate performance goals established by the Compensation Committee for you
and for the Company for fiscal year 2005. The bonus award, if any, will be paid
based on achievement of those goals, as determined by the Compensation Committee
after consideration of an assessment of your performance by the Nominating and
Governance Committee and recommendations by the Executive Chair. Except as
described in paragraph 5 below, you must be an active employee of the Company on
the date that incentive bonuses for fiscal year 2005 are distributed in order to
be eligible for an incentive bonus award.

4. Long Term Incentive Compensation.

      Effective January 4, 2005, pursuant to the Company's Second Amended and
Restated 1998 Stock Incentive Plan, as amended ("Plan"), and subject to the
approval of the Compensation Committee, the Company will grant to you an option
to purchase two hundred fifty thousand (250,000) shares of common stock of the
Company at a purchase price equal to the fair market value on January 4, 2005
("Option"). The Option shall be subject to the terms of an Incentive Stock
Option Agreement Granted Under The Second Amended and Restated 1998 Stock
Incentive Plan, as amended ("Initial Option Agreement")(including, but not
limited to, the vesting and accelerated vesting provisions), the Plan, and this
Offer Letter.

      In addition, you will be eligible to participate in any long-term
incentive plan for senior executives that the Board may adopt in mid-2005
pursuant to the eligibility, terms and conditions of any such plan. If such a
plan is not adopted, or if it does not include the CEO, then the Compensation
Committee will consider an additional stock option grant to you of an additional
two hundred fifty thousand (250,000) shares of common stock of the Company at a
purchase price equal to the fair market value on the date of such grant
("Additional Option"). The determination of the Compensation Committee as to
whether to grant you the Additional Option shall be made after consideration of
an assessment of your performance by the Nominating and Governance Committee and
the recommendations of the Executive Chair. The Additional Option shall be
subject to the terms of an Option Agreement ("Additional Option Agreement")
(including, but not limited to, the vesting and accelerated vesting provisions),
the Plan, and this Offer Letter.

      Your eligibility to participate in any long-term incentive plan(s) adopted
for senior executives after 2005 will be determined by the Compensation
Committee after consideration of an assessment of your performance by the
Nominating and Governance Committee and recommendations by the Executive Chair.

                                       2

5. Termination of Employment.

      Each party must give the other party at least thirty (30) days advance
written notice prior to terminating your employment, except that such notice is
not required in the event of your termination for Cause, as defined in the
Initial Option Agreement. Furthermore, there may be cases in which the Company,
in its sole discretion, determines that it is not in the best interests of the
Company to continue your employment for thirty (30) days after giving you notice
of termination, even if your termination is not for Cause. In such cases, the
Company reserves the right to provide you with thirty (30) days pay, at your
then-current base salary, in lieu of providing you with thirty (30) days notice.
Nothing in this provision is intended to, or does, alter your status as an
employee at will.

      If you terminate your employment for "Good Reason" following a "Change of
Control" as those terms are defined in the Initial Option Agreement and any
Additional Option Agreement (together, the "Option Agreements"),you shall have
such accelerated vesting rights as are set forth under the Option Agreements and
you shall also be entitled to lump sum cash payments equal to: two (2) years of
your then-current base salary and an award equal to two (2) times your
then-applicable annual incentive bonus at target. For purposes of this Letter
Offer, "bonus at target" shall be equal to fifty percent (50%) of your
then-current annual base salary.

      If you are involuntarily terminated for any reason other than "Cause" as
defined in the Option Agreements, you shall also be entitled to lump sum cash
payments equal to: one year of your then-current base salary; an amount equal to
12 times the monthly premium for continued health and dental insurance coverage
paid by the Company on your behalf in the month preceding your termination; and
an award of your then-applicable annual incentive bonus at target.

      In addition, if you are involuntarily terminated in 2005 for any reason
other than "Cause," as defined in the Option Agreements, the Company will
accelerate the number of shares which will be deemed vested as though the Grant
Date of the Option Agreements were the date eighteen (18) months prior to the
Grant Date; if you are so terminated in 2006, the Company will accelerate the
number of shares which will be deemed vested as though the Grant Date of the
Option Agreements were the date twelve (12) months prior to the Grant Date; and
if you are so terminated in 2007, the Company will accelerate the number of
shares which will be deemed vested as though the Grant Date of the Option
Agreements were the date six (6) months prior to the Grant Date.

      In addition, for termination for any reason other than "Cause," as defined
in the Option Agreements, the Company will make a lump sum matching contribution
to your 401(k) plan for contributions made by you during such calendar year,
provided that (1) the Company has a 401(k) matching plan in effect at the time
of such termination, (2) your separation agreement goes into effect prior to the
last date of your employment with the Company, and (3) any such match shall be
subject to the terms and conditions (including any applicable maximum on the
amount of the match in a calendar year) of such plan and all applicable laws and
regulations.

      Contemporaneously with the drafting of your new Offer Letter, the Company
also will amend the last sentence of Section 2 (e)(i) of your Option Agreements
to read "The Participant shall be considered to have been discharged for `Cause'
if the Company makes a preliminary

                                       3
<PAGE>
determination, within 30 days after the Participant's resignation, that
discharge for Cause was warranted, provided that, prior to making any final
determination of discharge for Cause, the Company gives the Participant
reasonable notice and opportunity to be heard." In addition, the Company also
will delete the second sentence of Section 2 (e)(ii) of your Option Agreements
to eliminate the Company's right to cure an event or circumstance that
constitutes "Good Reason."

      If, while you are CEO of the Company, you die or are deemed to be suffer
from a "long term disability" (as that term is defined in the Company's
then-current long term disability plan), in addition to the benefits under any
applicable Company life insurance policy or long term disability plan to which
you have subscribed, you (or, in the event of your death, your estate) shall
receive full vesting of all of your then-outstanding shares and stock options as
well as a lump sum cash payment equal to: one (1) year of your then-current base
salary; an award equal to your then-applicable annual incentive bonus at target,
and an amount equal to 12 times the monthly premium for continued health and
dental insurance coverage paid by the Company on your behalf in the month
preceding your termination. The lump sum shall be paid within thirty (30) days
of your termination, provided that you (or, in the event of your death, an
authorized representative of your estate) have signed the Company's separation
agreement, including a release, as described below.

      Any lump sum payment to be paid under this Section 5 shall be paid within
thirty (30) days after your termination, provided that you have signed the
Company's separation agreement, including a release, which is in substantially
the same form as the attached and within such time as may be reasonably
determined by the Company. The Company reserves the right to make such changes
to the form of separation agreement as may be necessary to comply with
applicable law and/or changes in its form separation agreement. In the event
that your employment terminates due to your resignation and, after you sign any
release, the Company makes a final determination that discharge for Cause is
warranted pursuant to the Option Agreements, then such release shall not negate
your reasonable notice and opportunity to be heard nor your right to raise
defenses and/or claims against the Company regarding such determination. .

6. Employee Benefits.

      Except as provided herein, you shall be entitled to health insurance,
vacation, and other employee benefits provided to senior executives of the
Company, so long as and to the extent any such benefit is provided by the
Company and provided you meet any eligibility requirements to participate. The
Company may alter, modify, add to or delete any employee benefits maintained for
its employees generally at any time, as it, in its sole judgment, determines to
be appropriate.

7. Invention And Non-Disclosure Agreement And Non-Competition and
Non-Solicitation Agreement.

      The Invention and Non-Disclosure Agreement dated March 28, 1998 between
you and the Company and the Non-Competition and Non-Solicitation Agreement dated
October 28, 1998 by and between you and the Company (the
"Non-Disclosure/Non-Competition Agreements") shall remain in full force and
effect. You agree that the change in your title, duties and compensation does
not affect the validity of the aforementioned agreements. You acknowledge and
agree that in your new role as CEO, you will continue to be bound and abide by
your obligations in the Non-Disclosure/Non-Competition Agreements.

executed by both the Company and you.

                            AKAMAI TECHNOLOGIES, INC.

                 Incentive Stock Option Agreement Granted Under
        Second Amended and Restated 1998 Stock Incentive Plan, as Amended

1. Grant of Option.

      This Incentive Stock Option Agreement (this "Agreement") evidences the
grant by Akamai Technologies, Inc., a Delaware corporation (the "Company"), on
January 4, 2005 (the "Grant Date") to Paul Sagan, an employee of the Company
(the "Participant"), of an option to purchase, in whole or in part, on the terms
provided herein and in the Company's Second Amended and Restated 1998 Stock
Incentive Plan, as amended (the "Plan") a total of 250,000 shares (the "Shares")
of common stock, $0.01 par value per share, of the Company ("Common Stock") at
$12.20 per Share. Unless earlier terminated, this option shall expire on January
4, 2015 (the "Final Exercise Date").

      It is intended that the option evidenced by this agreement shall, to the
extent it so qualifies, be an incentive stock option as defined in Section 422
of the Internal Revenue Code of 1986, as amended and any regulations promulgated
there under (the "Code"). Under the terms of the Code, all or a portion of this
option may not qualify as an incentive stock option. Schedule A hereto sets
forth the number of shares with respect to which this option qualifies as an
incentive stock option as of the date of grant. Except as otherwise indicated by
the context, the term "Participant", as used in this option, shall be deemed to
include any person who acquires the right to exercise this option validly under
its terms.

2. Vesting Schedule.

      (a)   General. Subject to the terms and conditions set forth in this
Agreement, including the accelerated vesting provisions set forth in Sections
2(b), (c) and (d) below, this option will become exercisable ("vest") as to 25%
of the original number of Shares on the first anniversary of the Grant Date and
as to an additional 6.25% of the original number of Shares 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.

      (b)   Accelerated Vesting Upon a Change in Control Event. If within twelve
months following a Change in Control Event, Mr. Sagan terminates his employment
for Good Reason, the number of shares as to which this option has vested under
Section 2(a) shall be increased by the number of shares determined by a
calculation pursuant to Section 2(a) as though the Grant Date were the date that
is two years prior to the Grant Date.

      (c)   Accelerated Vesting Upon a Termination Without Cause.

      (i)   If, on or prior to December 31, 2005, Mr. Sagan's employment with
      the Company is involuntarily terminated for any reason other than Cause,
      the number of shares as to which this option has vested under Section 2(a)
      shall be increased by the number of shares determined by a calculation
      pursuant to Section 2(a) as though the Grant Date were the date that is 18
      months prior to the Grant Date.

                                  Page 1 of 7
<PAGE>
      (ii)  If, during 2006, Mr. Sagan's employment with the Company is
      involuntarily terminated for any reason other than Cause, the number of
      shares as to which this option has vested under Section 2(a) shall be
      increased by the number of shares determined by a calculation pursuant to
      Section 2(a) as though the Grant Date were the date that is 12 months
      prior to the Grant Date.

      (iii) If, during 2007, Mr. Sagan's employment with the Company is
      involuntarily terminated for any reason other than Cause, the number of
      shares as to which this option has vested under Section 2(a) shall be
      increased by the number of shares determined by a calculation pursuant to
      Section 2(a) as though the Grant Date were the date that is 6 months prior
      to the Grant Date.

      (d)   Acceleration Upon Death or Disability. If the Participant dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to
the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "Cause" as specified in
paragraph (e) below, 100% of the unvested Shares shall automatically become
vested as of the date of death, in the case of death, or final determination of
disabled status, in the case of disability.

      (e)   Cumulative. The right of exercise in Sections 2(b), (c) and (d)
hereof shall be cumulative so that to the extent the option is not exercised in
any period to the maximum extent permissible it shall continue to be
exercisable, in whole or in part, with respect to all shares for which it is
vested until the earlier of the Final Exercise Date or the termination of this
option under Section 3 hereof or the Plan.

      (f)   Definitions.

      (i)   Cause shall mean willful misconduct by the Participant or willful
      failure by the Participant to perform his responsibilities to the Company
      [including, without limitation, breach by the Participant of any provision
      of (A) that certain Invention and Non-Disclosure Agreement, dated October
      28, 1998, by and between the Company and the Participant (the "Invention
      Agreement"), (B) that certain Non-Competition and Non-Solicitation
      Agreement, dated October 28, 1998, by and between the Company and the
      Participant (the "Non-Competition Agreement"), (C) that certain offer
      letter agreement dated January 4, 2005 between the Company and the
      Participant (the "Employment Agreement") or (D) any other employment,
      consulting, advisory, nondisclosure, non-competition or other similar
      agreement between the Participant and the Company)], or a willful
      violation of Company policies including, without limitation, the Code of
      Business Ethics (or successor policy), in any instance as determined by
      the Board of Directors of the Company, which determination shall be
      conclusive. The Participant shall be considered to have been discharged
      for "Cause" if the Company makes a preliminary determination, within 30
      days after the Participant's resignation, that discharge for cause was
      warranted, provided that, prior to making any final determination of
      discharge for Cause, the Company gives the Participant reasonable notice
      and opportunity to be heard. In addition, if the Participant resigns,
      signs a release with the Company, and the Company then makes such a
      determination of discharge for Cause, then such release shall not negate
      the Participant's reasonable notice and opportunity to be heard nor the
      Participant's right to raise defenses and/or claims against the Company
      regarding such determination.

      (ii)  Good Reason shall mean the occurrence, without the Participant's
      written consent, of any of the events or circumstances set forth in
      clauses (A) through (E) below.

            (A)   the assignment to the Participant of duties inconsistent in
            any material respect with the Participant's position (including
            status, offices, titles and reporting

                                  Page 2 of 7
<PAGE>
            requirements), authority or responsibilities as set forth in the
            Employment Agreement, or any other action or omission by the Company
            which results in a material diminution in such position, authority
            or responsibilities. Changes in job title, reporting relationship,
            and responsibilities alone shall not constitute Good Reason provided
            the resulting position does not result in a material diminution of
            the Participant's position, authority or responsibilities.

            (B)   a material reduction in the Participant's annual base salary
            as in effect on the Grant Date or as the same was or may be
            increased thereafter from time to time, other than in the case of
            reductions in salary or bonus eligibility with respect to similarly
            situated employees of the Company generally;

            (C)   the failure by the Company to (1) continue in effect any
            material compensation or benefit plan or program (including without
            limitation any life insurance, medical, health and accident or
            disability plan and any vacation or automobile program or policy) (a
            "Benefit Plan") in which the Participant participates or which is
            applicable to the Participant immediately prior to the Grant Date,
            unless an equitable arrangement (embodied in an ongoing substitute
            or alternative plan or cash compensation) has been made with respect
            to such plan or program, (2) continue the Participant's
            participation therein (or in such substitute or alternative plan) on
            a basis not materially less favorable, both in terms of the amount
            of benefits provided and the level of the Participant's
            participation relative to other participants, than the basis
            existing immediately prior to the Grant Date or (3) award cash
            bonuses to the Participant in amounts and in a manner substantially
            consistent with past practice in light of the Company's financial
            performance; other than in the cases of (1), (2) or (3) above of
            such failures by the Company that apply to similarly situated
            employees of the Company generally;

            (D)   a change by the Company in the location at which the
            Participant performs his principal duties for the Company to a new
            location that is both (i) outside a radius of 35 miles from the
            Participant's principal residence immediately prior to the Grant
            Date and (ii) more than 20 miles from the location at which the
            Participant performed his principal duties for the Company
            immediately prior to the Grant Date; and

            (E)   any material breach by the Company of this Agreement or the
            Employment Agreement.

3. Exercise of Option.

      (a)   Form of Exercise. In order to exercise this option, the Participant
shall notify the Company's third-party stock option plan administrator, Charles
Schwab & Co., or any successor appointed by the Company (the "Plan
Administrator"), of the Participant's intent to exercise this option, and shall
follow the procedures established by the Plan Administrator for exercising stock
options under the Plan and provide payment in full in the manner provided in the
Plan. The Participant may purchase less than the number of shares covered
hereby, provided that no partial exercise of this option may be for any
fractional share.

      (b)   Continuous Relationship with the Company Required. Except as
otherwise provided in this Section 3, this option may not be exercised unless
the Participant, at the time he or she exercises this option, is, and has been
at all times since the Grant Date, an employee, officer or director of, or
consultant

                                  Page 3 of 7
<PAGE>
or advisor to, the Company or any parent or subsidiary of the Company as defined
in Section 424(e) or (f) of the Code (an "Eligible Participant").

      (c)   Termination of Relationship with the Company. If the Participant

paragraphs (d) and (e) below, the right to exercise this option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), provided that (i) this option shall be exercisable only to the extent
that the Participant was entitled to exercise this option on the date of such
cessation, and (ii) to the extent that the option or any portion thereof is
exercised at any time later than three months after the date that the
Participant ceases to be an employee of the Company or any parent or subsidiary
of the Company as defined in Section 424(e) or (f) of the Code, the option shall
be a non-qualified stock option. Notwithstanding the foregoing, if the
Participant, prior to the Final Exercise Date, violates the provisions of the
Invention Agreement, the Non-Competition Agreement, the Employment Agreement,
the Code of Business Ethics (or successor policy) or the non-competition or
confidentiality provisions of any other employment contract, confidentiality and
nondisclosure agreement or other agreement between the Participant and the
Company, the right to exercise this option shall terminate immediately upon such
violation.

      (d)   Exercise Period Upon Death or Disability. If the Participant dies or
becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to
the Final Exercise Date while he or she is an Eligible Participant and the
Company has not terminated such relationship for "cause" as specified in
paragraph (e) below, this option shall be exercisable, within the period of one
year following the date of death or disability of the Participant by the
Participant , provided that (i) this option shall be exercisable only to the
extent that this option was exercisable by the Participant on the date of his or
her death or disability, (ii) this option shall not be exercisable after the
Final Exercise Date, and (iii) to the extent that the option or any portion
thereof is exercised at any time later than one year after the Participant's
termination as an employee of the Company or any parent or subsidiary of the
Company (as defined in Section 424(e) or (f) of the Code) by reason of his or
her disability (as defined in Section 22(e)(3) of the Code), the option shall be
a non-qualified stock option.

      (e)   Discharge for Cause. If the Participant, prior to the Final Exercise
Date, is discharged by the Company for Cause, the right to exercise this option
shall terminate immediately upon the effective date of such discharge.

4. Withholding.

      No Shares will be issued pursuant to the exercise of this option unless
and until the Participant pays to the Company, or makes provision satisfactory
to the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this option.

5. Nontransferability of Option.

      This option may not be sold, assigned, transferred, pledged or otherwise
encumbered by the Participant, either voluntarily or by operation of law, except
by will or the laws of descent and distribution, and, during the lifetime of the
Participant, this option shall be exercisable only by the Participant.

Participant shall notify the Company in writing of such disposition.
