TO: The Persons listed on Exhibit 1.01 hereto

Re: Series B Convertible Preferred Stock and Series C Convertible Preferred
    Stock

Ladies and Gentlemen:

     Akamai Technologies, Inc., a Delaware corporation (the "Company"), agrees
with each of you as follows:

                                    ARTICLE I

                       PURCHASE, SALE AND TERMS OF SHARES


     1.01 The Preferred Shares. The Company has authorized the issuance and sale
of up to 1,327,500 shares of its previously authorized but unissued shares of
Series B Convertible Preferred Stock, par value $.01 per share (the "Series B
Preferred Stock"), at a purchase price of $15.066 per share to the Persons
(collectively, the "Purchasers" and, individually, a "Purchaser") and in the
respective amounts set forth in Exhibit 1.01 hereto. The designation, rights,
preferences and other terms and conditions relating to the Series B Preferred
Stock are as set forth on Exhibit 1.01A hereto. The Company has authorized the
issuance and sale of up to 145,195 shares of its previously authorized but
unissued shares of Series C Convertible Preferred Stock, par value $.01 per
share (the "Series C Preferred Stock"), at a purchase price of $34.436 per share
to the Purchasers and in the respective amounts set forth in Exhibit 1.01
hereto. The designation, rights, preferences and other terms and conditions
relating to the Series C Preferred Stock are as set forth on Exhibit 1.01B
hereto. The Series B Preferred Stock and the Series C Preferred Stock are
sometimes referred to herein as the "Preferred Shares."

     1.02 The Converted Shares. The Company has authorized and has reserved and
covenants to continue to reserve, free of preemptive rights and other
preferential rights, a sufficient number of its previously authorized but
unissued shares of Common Stock to satisfy the rights of conversion of the
holders of the Preferred Shares. Any shares of Common Stock issuable upon
conversion of the Preferred Shares, and such shares when issued, are herein
referred to as the "Converted Shares."

     1.03 The Shares. The Preferred Shares and the Converted Shares are
sometimes collectively referred to herein as the "Shares."
<PAGE>   6
     1.04 Purchase Price and Closing.

          (a) The Closing. The Company agrees to issue and sell to the
Purchasers and, subject to and in reliance upon the representations, warranties,
covenants, terms and conditions of this Agreement, the Purchasers, severally but
not jointly, agree to purchase that number of the shares of Series B Preferred
Stock set forth opposite their respective names in Exhibit 1.01. The aggregate
purchase price of the shares of Series B Preferred Stock being purchased by each
Purchaser is set forth opposite such Purchaser's name in Exhibit 1.01. The
purchase and sale shall take place at a closing (the "Closing") to be held on or
before April 16, 1999, at 10:00 A.M., at such location and at such time as may
be mutually agreed upon, subject to the satisfaction of all of the conditions to
the Closing specified in Article II herein. At the Closing the Company will
issue and deliver certificates evidencing the shares of Series B Preferred Stock
to be sold at the Closing to each of the Purchasers (or its nominee) against
payment of the full purchase price therefor by (i) wire transfer of immediately
available funds to an account designated by the Company, (ii) check payable to
the order of the Company or its designee, or (iii) any combination of (i) and
(ii) above.

          (b) Option. The Baker Fund shall have the option (the "Option"),
exercisable in whole or in part in its sole discretion, to purchase from the
Company up to a maximum of 145,195 shares of Series C Preferred Stock (the
"Option Shares") at a subsequent closing (the "Subsequent Closing") at a
purchase price of $34.436 per share, under the terms and conditions of this
Agreement. The Baker Fund shall exercise the Option by giving notice (the
"Option Notice") to the Company of its intent to exercise its Option. The Option
Notice shall indicate the number of Option Shares to be purchased by the Baker
Fund at the Subsequent Closing and shall fix the date for the Subsequent
Closing, which shall be any date no earlier than the date of the Closing and no
later than the earlier of (i) December 31, 1999 and (ii) the date immediately
prior to the consummation of a Qualified Public Offering.

          (c) Subsequent Closing. The Subsequent Closing shall be held at such
location and at such time as shall be specified by the Company and the
respective Purchaser. At the Subsequent Closing, the Company will issue and
deliver certificates evidencing the shares of Series C Preferred Stock to be
sold at such Subsequent Closing against payment of the full purchase price by
(i) wire transfer of immediately available funds to an account designated by the
Company, or (ii) check payable to the order of the Company or its designee, or
(iii) any combination of (i) and (ii) above. At the Subsequent Closing, the
Purchaser purchasing shares of Series C Preferred Stock shall have received a
certificate from the President of the Company stating that the representations
and warranties of the Company contained in Article III hereof and otherwise made
by the Company in writing in connection with the transactions contemplated
hereby are true and correct (giving effect to updates, if any, to the exhibits
setting forth exceptions to the representations and warranties of the Company)
and that all conditions required to be performed prior to or at the Subsequent
Closing have been performed as of the Subsequent Closing (such certificate
referred to herein as a "Bring-Down Certificate") and shall be entitled to
receive such other certificates, opinions and other documents as shall be
reasonably requested.


                                       2

          (d) Debt Securities.

              (i) In the event that the Board of Directors so determines, the
Company may require each of the Purchasers to purchase, severally and not
jointly, a new issue of senior subordinated notes and warrants (the "Debt
Securities") of the Company in the respective amounts set forth in Exhibit
1.4(d)(i), and having the terms substantially as set forth in Exhibit
1.4(d)(ii). The Company may exercise such right one time only on at least five
(5) business days' prior notice to the Purchasers, and the closing of the sale
and purchase of the Debt Securities (the "Debt Closing") shall occur no earlier
than the purchase and sale of all of the Series B Preferred Stock to be sold
hereunder and no later than thirty-five (35) days from the date of the Closing
hereunder; provided, however, that the date of the Debt Closing may be extended
with the consent of the Company and the affirmative vote or consent of the
Purchasers having 60% of the commitments set forth in Exhibit 1.4(d)(i). The
obligation of any Purchaser to purchase its respective portion of Debt
Securities shall be subject to the preparation, execution and delivery of
definitive documentation, including a Purchase Agreement, Forms of Senior Note
and Warrant, based on this Agreement (to the extent applicable) and reasonably
satisfactory to the parties, which documentation shall contain (i)
representations and warranties substantially the same as contained in Article
III herein (with appropriate adjustments to reflect the terms of the Debt
Securities) and (ii) conditions substantially equivalent to those contained in
Article II herein, and shall be subject to the further condition of there having
been no material adverse change in the business, operations, affairs or
condition of the Company or in its properties or assets taken as a whole, from
that as of the date hereof.

              (ii) If, for any reason other than the Company's unwillingness to
sell or other material breach of this Agreement or the Amended and Restated
Stockholders Agreement, any Purchaser does not purchase its respective portion
of Debt Securities as contemplated by Section 1.04(d)(i) (including due to a
material adverse change in the business, operations, affairs or condition of the
Company or in its properties or assets), the Company shall have the right to
repurchase, and, if the Company so elects, the Purchaser not purchasing its
respective portion of Debt Securities shall be obligated to sell to the Company,
such Purchaser's shares of Series B Preferred Stock at the price per share paid
for such shares by such Purchaser hereunder. The Company may exercise its right
to repurchase such shares by delivering written notice (the "Repurchase Notice")
to the Purchaser within sixty (60) days after such Purchaser's failure to
purchase its respective portion of Debt Securities. Such Purchaser shall be
obligated to sell such shares to the Company within ten (10) days after receipt
of the Repurchase Notice.

          (e) Second Closing.


              (i) In the event that the Company shall not have sold all
1,327,500 shares of the Series B Preferred Stock at the Closing, the Company and
the Purchasers agree that at a second closing (the "Second Closing"), the
Company may issue and sell any of the unsold shares of the Series B Preferred
Stock ("Additional Shares") to one or more of the Persons listed on Exhibit
1.04(e) (the "Additional Purchasers"). The Company and the Purchasers further
agree that (i) the Company shall amend this Agreement solely to provide for the
issuance of the Additional Shares to the Additional Purchasers at the same price
and under the terms and conditions of this Agreement and (ii) the Additional
Purchasers shall become


                                       3
<PAGE>   8
parties to this Agreement as amended by executing counterparts hereof. The terms
"Series B Preferred Stock", "Preferred Shares", "Purchaser" and "Purchasers",
when used in this Agreement, shall respectively be deemed to include such
Additional Shares as are issued and such Additional Purchaser and Additional
Purchasers as exist from time to time and the term "Closing" shall include the
Second Closing where appropriate.

              (ii) The Second Closing shall be held at such location and at such
times and dates, but on or before May 14, 1999, as shall be specified by the
Company and the Additional Purchasers. At the Second Closing, the Company will
issue and deliver certificates evidencing the Additional Shares to be sold at
the Second Closing against payment of the full purchase price by (i) wire
transfer of immediately available funds to an account designated by the Company,
(ii) check payable to the order of the Company or its designee, or (iii) any
combination of (i) and (ii) above. At the Second Closing, the Additional
Purchasers purchasing Additional Shares at the Second Closing shall have
received a certificate from the President of the Company stating that the
representations and warranties of the Company contained in Article III hereof
and otherwise made by the Company in writing in connection with the transactions
contemplated hereby are true and correct (giving effect to updates, if any, to
the exhibits setting forth exceptions to the representations and warranties of
the Company) and that all conditions required to be performed prior to or at the
Second Closing have been performed as of such Subsequent Closing.

          (f) Special Option. The Baker Fund shall have the option (the "Special
Option"), exercisable in whole or in part in its sole discretion, to purchase up
to five percent (5%) of the total number of shares of Common Stock or other
securities (the "Special Option Shares") offered in the initial public offering
of the Company (including in respect of the Special Option Shares) at a purchase
price per share equal to the price per share at which such shares are offered to
the public and on the same settlement and other terms as offered to the public.
The Baker Fund shall exercise the Special Option by giving notice to the Company
of its intent to exercise its Special Option no later than the pricing of the
initial public offering, specifying the number of Special Option Shares in
respect of which the Special Option is being exercised. All of the Special
Option Shares in respect of which the Special Option is exercised shall be fully
registered under the Securities Act. The Company agrees to cause each
underwriter of the Company's initial public offering to abide by the terms of
the Baker Fund's Special Option. The Baker Fund agrees not to offer, sell,
contract to sell, grant any option for the sale of or otherwise transfer or
dispose of any Special Option Shares for the period of the "lock-up" applicable
to other existing investors generally (not to exceed one hundred eighty (180)
days following the date of such initial public offering) without the prior
written consent of the managing underwriter of such initial public offering.

     1.05 Use of Proceeds. The Company shall use the proceeds from the sale of
the Preferred Shares under this Agreement for working capital purposes,
including Capital Expenditures, and general corporate purposes.


     1.06 Representations and Warranties by the Purchasers. Each of the
Purchasers represents and warrants, severally, but not jointly, that (a) it will
acquire the Preferred Shares and, if applicable, any Option Shares to be
acquired by it for its own account and that the


                                       4
<PAGE>   9
Preferred Shares and, if applicable, any Option Shares are being and will be
acquired by it for the purpose of investment and not with a view to distribution
or resale thereof; (b) the execution of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by all necessary
action on the part of such Purchaser, and this Agreement has been duly executed
and delivered, and constitutes a valid, legal, binding and enforceable agreement
of such Purchaser; (c) it has taken no action which would give rise to any claim
by any other person for any brokerage commissions, finders' fees or the like
relating to this Agreement or the transactions contemplated hereby; (d) such
Purchaser has had the opportunity to ask questions of and receive answers from
representatives of the Company concerning the terms of the offering of the
Preferred Shares and the Option Shares and to obtain additional information
concerning the Company and its business; and (e) such Purchaser has the ability
to evaluate the merits and risks of an investment in the Preferred Shares and
the Option Shares and can bear the economic risks of such investment. The
acquisition by each Purchaser of the Preferred Shares and the Option Shares
acquired by it shall constitute a confirmation of the representations and
warranties made by each such Purchaser as at the date of such acquisition. Each
of the Purchasers further represents that it understands and agrees that, until
registered under the Securities Act or transferred pursuant to the provisions of
Rule 144 as promulgated by the Commission, all certificates evidencing any of
the Shares, whether upon initial issuance or upon any transfer thereof, shall
bear a legend, prominently stamped or printed thereon, reading substantially as
follows:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS. THESE SECURITIES MAY NOT BE SOLD, MORTGAGED, PLEDGED,
     HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
     STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
     AND APPLICABLE STATE SECURITIES LAWS, OR THE AVAILABILITY OF AN EXEMPTION
     FROM THE REGISTRATION PROVISIONS OF THE SECURITIES ACT OF 1933, AS AMENDED,
     AND APPLICABLE STATE SECURITIES LAWS."


                                   ARTICLE II

                    CONDITIONS TO THE PURCHASERS' OBLIGATION

     3.01 Organization and Standing. The Company is a duly organized and validly
existing corporation in good standing under the corporate laws of the State of
Delaware and has all requisite corporate power and authority for the ownership
and operation of its properties and for the carrying on of its business as now
conducted or as now proposed to be conducted. The Company is duly licensed or
qualified and in good standing as a foreign corporation authorized to do
business in all jurisdictions wherein the character of the property owned or
leased, or the nature of the activities conducted, by it makes such licensing or
qualification necessary as set forth in Exhibit 3.01, except where the failure
to so qualify would not have a material adverse effect on the business,
operations, affairs or condition of the Company or in its properties or assets
taken as a whole, or which might call into question the validity of this
Agreement, any of the Shares, or any action taken or to be taken pursuant hereto
or thereto (a "Material Adverse Effect").

     3.02 Corporate Action. The Company has all necessary corporate power and
has taken all corporate action required to enter into and perform this
Agreement, the Amended and Restated Registration Rights Agreement, the Amended
and Restated Stockholders Agreement and any other agreements and instruments
executed in connection herewith (collectively, the "Financing Documents"). The
Financing Documents are valid and binding obligations of the Company,
enforceable in accordance with their terms. The issuance, sale and delivery of
the Preferred Shares in accordance with this Agreement, the issuance, sale and
delivery of the Option Shares have been duly authorized and reserved for
issuance, and the issuance, sale and delivery of the Converted Shares have been
duly authorized and reserved for issuance, as the case may be, by all necessary
corporate action on the part of the Company. Sufficient authorized but unissued
shares of Common Stock have been reserved by appropriate corporate action in
connection with the prospective conversion of the Preferred Shares and the
Option Shares at the initial conversion price, and the issuance of the Preferred
Shares and the Option Shares is not, and the issuance of the Converted Shares
upon the conversion of the Preferred Shares and the Option Shares will not be,
subject to preemptive rights or other preferential rights in any present
stockholders of the Company and will not conflict with any provision of any
agreement or instrument to which the Company is a party or by which it or its
property is bound.

     3.03 Governmental Approvals. Except for the filing of any notice subsequent
to the Closing that may be required under applicable state and/or federal
securities laws (which, if required, shall be filed on a timely basis and a copy
of which shall be provided to the Purchasers and their counsel), no
authorization, consent, approval, license, exemption of or filing or
registration with any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, is or will be necessary
for the execution and delivery by the Company of this Agreement, for the offer,
issue, sale and delivery of the Preferred Shares and the Option Shares, or for
the performance by the Company of its obligations under this Agreement or the
Shares.

     3.04 Litigation. Except as set forth in Exhibit 3.04, there is no
litigation or governmental proceeding or investigation pending or, to the
knowledge of the Company, threatened against the Company affecting any of its
respective properties or assets, or against any


                                       8
<PAGE>   13
officer or Key Employee relating to such person's performance of duties for the
Company or relating to his stock ownership in the Company or otherwise relating
to the business of the Company, nor to the knowledge of the Company has there
occurred any event or does there exist any condition on the basis of which any
such litigation, proceeding or investigation might properly be instituted.
Neither the Company nor, to the knowledge of the Company, any officer, Key
Employee or holder of more than 5% of the Common Stock of the Company (other
than any Purchaser) is in default with respect to any order, writ, injunction,
decree, ruling or decision of any court, commission, board or other governmental
agency specifically naming the Company, such officer, Key Employee or holder of
more than 5% of the Common Stock of the Company. Except as set forth in Exhibit
3.04, there are no actions or proceedings pending or, to the knowledge of the
Company, threatened against the Company or against any officer or Key Employee
which could reasonably be expected to result, either in any case or in the
aggregate, in any Material Adverse Effect. The foregoing sentences include,
without limiting their generality, actions pending or, to the knowledge of the
Company, threatened (or any basis therefor), involving the prior employment of
any of the Company's officers or employees (including any Key Employees) or
their use in connection with the Company's business of any information or
techniques allegedly proprietary to any of their former employers.

relating to the employment of any such officer or Key Employee by the Company,
the nature of the business conducted or to be conducted by the Company or
relating to the use of trade secrets or proprietary or confidential information
of others. The Company has no reason to believe that the employment of the
Company's officers and Key Employees will subject the Company or any Purchaser
to any liability to third-parties. The Company has entered into Noncompetition
and Nonsolicitation Agreements and Invention and Nondisclosure Agreements with
each of its employees.

          (b) To the knowledge of the Company, no officer of the Company nor
any Key Employee of the Company whose termination, either individually or in the

respects with the terms and provisions of this Agreement and of its Certificate
of Incorporation and By-laws, and in all material respects with the terms and
provisions of all mortgages, indentures, leases, agreements and other
instruments by which it is bound or to which it or any of its respective
properties or assets are subject. The Company is in compliance with all
judgments specifically naming the Company or any of the Founders, decrees,
governmental orders specifically naming the Company or any of the Founders,
statutes, rules or regulations by which it is bound or to which any of its
properties or assets are subject. Neither the execution and delivery of this
Agreement or the issuance of the Shares, nor the consummation of any transaction
contemplated by this Agreement, has constituted or resulted in or will
constitute or

or part of a provision of this Agreement or the terms of the Series B Preferred
Stock or the Series C Preferred Stock; but this Agreement and the terms of the
Series B Preferred Stock and the Series C Preferred Stock, as the case may be,
shall be reformed and construed as if such invalid or illegal or unenforceable
provision, or part of a provision, had never been contained herein, and such
provisions or part reformed so that it would be valid, legal and enforceable to
the maximum extent possible.

     6.09 Governing Law. This Agreement shall be construed and enforced in
accordance with and governed by the General Corporation Law of the State of
Delaware as to matters within the scope thereof, and as to all other matters
shall be governed by and construed in accordance with the internal laws of the

     6.11 Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument, and any of the parties hereto may execute this Agreement by signing
any such counterpart.

     6.12 Further Assurances. From and after the date of this Agreement, upon
the request of any Purchaser or the Company, the Company and the Purchasers
shall execute and deliver such instruments, documents and other writings as may
be reasonably necessary or desirable to confirm and carry out and to effectuate
fully the intent and purposes of this Agreement and the Shares.

     6.13 Indemnification.

          (a) The Company shall, with respect to the representations, warranties
and agreements made by it herein, indemnify, defend and hold the Purchasers
harmless against all liability, loss or damage, together with all reasonable
costs and expenses related thereto (including legal and accounting fees and
expenses (collectively, "Losses" and individually, a "Loss")), arising from the
untruth, inaccuracy or breach of any such representations, warranties or
agreements of the Company. Without limiting the generality of the foregoing, the
Purchasers shall be deemed to have suffered a Loss as a result of the untruth,
inaccuracy or breach of any such representations or warranties if such Loss
shall be suffered by the Company as a result of, or in connection with, such
untruth, inaccuracy or breach of any facts or circumstances constituting such
untruth, inaccuracy or breach. To claim a Loss, one or more Purchasers shall
deliver to the Company a notice (the "Loss Notice") specifying in reasonable
detail the nature and estimated amount of the Loss. At the time of delivery of
the Loss Notice to the Company, a duplicate copy of the Loss Notice shall be
delivered to the other Purchasers. A determination as to the existence and
amount of the Loss claimed in the Loss Notice shall be made in accordance with
Section 6.13(c) below. Any dispute regarding a Loss shall be determined as set
forth in Section 6.13(c) herein.

          (b) The representations and warranties of the Company set forth in
this Agreement shall survive the Closing until April 16, 2001 and be of no
further force or effect as of such date, except that (i) the representations and
warranties set forth in Sections 3.13 and 3.18 shall survive the Closing until
April 16, 2000, and (ii) the representations and warranties set forth in Section
3.15 shall survive the Closing forever and shall not terminate.

          (c) Within 10 days after delivery of the Loss Notice, the Purchasers
shall designate a representative (the "Purchaser Representative"). The Company
and the Purchaser Representative shall thereafter attempt in good faith for 30
days to agree upon the amount of the Loss claimed in the Loss Notice (the "Loss
Amount") and the then fair market value of one share of Series B Preferred Stock
and one share of Series C Preferred Stock after giving effect to the Loss
(respectively, the "Current Series B Value" and the "Current Series C Value").
If no such agreement can be reached, the Company and the Purchaser
Representative shall each promptly select an arbitrator and thereafter the two
arbitrators shall select a third arbitrator. The three arbitrators shall
thereafter determine, by majority vote and pursuant to the then rules of the
American Arbitration Association, the Loss Amount, the Current Series B Value
and the Current Series C Value. Each of the arbitrators shall be a member in
good standing of the American

Arbitration Association. The Company and the Purchaser Representative shall each
be permitted to submit written positions and arguments to the arbitrators
concerning the matters at issue before the arbitrators. The fees and expenses of
the arbitrators shall be borne (i) 100% by the Company, if the Loss Amount as
determined by the arbitrators is greater than or equal to 50% of the estimated
amount of the Loss as set forth in the Loss Notice, or (ii) 100% by the
Purchaser or Purchasers submitting the Loss Notice, if the Loss Amount as
determined by the arbitrators is less than 50% of the estimated amount of the
Loss as set forth in the Loss Notice.
