                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information about Akamai and the common stock being sold in this offering and
our financial statements and accompanying notes appearing elsewhere in this
prospectus.

                           AKAMAI TECHNOLOGIES, INC.

     We provide a global delivery service for Internet content that improves Web
site speed and reliability and protects against Web site crashes due to demand
overloads. Our FreeFlow service, which we market to large businesses and other
businesses with an Internet focus, delivers our customers' Web content through a
worldwide server network by locating the content geographically closer to their
users. Using software that is based on our proprietary mathematical formulas, or
algorithms, we monitor Internet traffic patterns and deliver our customers'
content by the most efficient route available. Our service is easy to implement
and does not require our customers or their Web site visitors to make any
hardware or software modifications. Using our FreeFlow service, our customers
have been able to more than double the speed at which they deliver content to
their users and, in some instances, have been able to improve speeds by ten
times or more.

     The ability of a Web site to attract users is in part based on the richness
of its content. Increasingly, Web site owners want to enhance their content by
adding graphics, such as photographs, images and logos, as well as deploying
newer technologies, such as video and audio streaming, animation and software
downloads. While richer content attracts more visitors, it also places
increasing demands on the Web site to deliver the content quickly and reliably.
As a result, Web site owners frequently elect to constrain the amount of rich
content on their Web sites, thus sacrificing the quality of the user experience
to maintain minimally acceptable performance levels.


     To use our service, customers identify and tag portions of their Web site
content that require significant amounts of bandwidth, such as advertising
banners, icons, graphics, video and audio streaming and software downloads.
These tagged items are delivered over our server network. When users request
this content, which we call "Akamaized" content, our FreeFlow service routes the
request to the server that is best able to deliver the content most quickly
based on the geographic proximity, performance and congestion of all available
servers on our network.



     Our technology originated from research that our founders began developing
at the Massachusetts Institute of Technology in 1995. We introduced our FreeFlow
service commercially in April 1999. As of October 5, 1999, we had 1,475 Akamai
servers deployed in 24 countries across 55 telecommunications networks,
providing our customers with a guaranteed global Internet content delivery
service. Our customers, which operate many highly trafficked Web sites, include
Apple Computer, CNN Interactive, Discovery Channel Online, Infoseek Corp., J.
Crew.com, The Motley Fool and Yahoo!.


     We currently sell our service primarily through a direct sales force. Our
plan is to continue to pursue heavily trafficked Web sites through our direct
sales force and to penetrate other markets through indirect distribution
channels. Currently our sales force is actively targeting primarily domestic
companies, focusing on the 300 Web sites that have the greatest number of
visitors, Fortune 100 companies and other companies with large operations in the
United States.

                              RECENT DEVELOPMENTS


     In August 1999, we entered into a strategic alliance with Cisco Systems to
enhance and jointly develop new content routing, switching and caching
technologies to improve the performance of Web content delivery. Cisco purchased
shares of our Series E convertible preferred stock for an aggregate purchase
price of approximately $49.0 million in August 1999.



     In September 1999, we entered into a strategic alliance with Microsoft
Corporation to integrate Microsoft technologies into the Akamai network. As part
of the agreement, we intend to integrate Microsoft Windows Media(TM)
technologies with our global Internet content delivery service, and we will
create a version of our software to support our FreeFlow service that works on
Microsoft Windows Server operating systems. In addition, Microsoft's Streaming
Media Division has agreed to become one of our Internet content delivery service
customers. Microsoft purchased shares of our Series F convertible preferred
stock for an aggregate purchase price of approximately $15.0 million in
September 1999. For more detailed information about our strategic alliances with
Cisco and Microsoft, see "Business -- Strategic Alliances" on page 31.

     Weighted average shares used in computing the pro forma basic and diluted
net loss per share have been calculated assuming the conversion of all shares of
convertible preferred stock outstanding as of June 30, 1999 into common stock as
if the shares had converted immediately upon issuance. Accordingly, accrued
dividends and accretion to redemption value are not included in the calculation
of pro forma basic and diluted loss per share. The pro forma as adjusted column
in the balance sheet data below gives effect to the conversion of all shares of
convertible preferred stock outstanding as of June 30, 1999 into common stock
upon the closing of this offering and the sale of the 8,000,000 shares of common
stock in this offering at an assumed initial public offering price of $17.00,
after deducting the estimated underwriting discounts and commissions and
estimated offering expenses payable by us.



     Pro forma as adjusted shares have not been adjusted for the issuance of
1,867,480 shares of Series E convertible preferred stock on August 6, 1999 and
985,545 shares of Series F convertible preferred stock on September 20, 1999.

                                  RISK FACTORS

     You should consider carefully the risks described below before you decide
to buy our common stock. If any of the following risks actually occur, our
business, financial condition or results of operations would likely suffer. In
such case, the trading price of our common stock could fall, and you may lose
all or part of the money you paid to buy our common stock.

RISKS RELATED TO OUR BUSINESS

  OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE WE HAVE A LIMITED OPERATING
HISTORY.

     We were founded in August 1998 and began offering our FreeFlow service in
April 1999. We have limited meaningful historical financial data upon which to
base planned operating expenses and upon which investors may evaluate us and our
prospects. In addition, our operating expenses are largely based on anticipated
revenue trends and a high percentage of our expenses are and will continue to be
fixed in the short-term. You should consider the risks and difficulties
frequently encountered by companies like ourselves in a new and rapidly evolving
market. Our ability to sell our service and the level of success we achieve,
depends, among other things, on the level of demand for Internet content
delivery services, which is a new and rapidly evolving market. Our business
strategy may be unsuccessful, and we may not successfully address the risks we
face.

  WE ARE ENTIRELY DEPENDENT ON OUR INTERNET CONTENT DELIVERY SERVICE AND OUR
FUTURE REVENUE DEPENDS ON ITS COMMERCIAL SUCCESS.


     Our future growth depends on the commercial success of our Internet content
delivery service. Our FreeFlow service or other services under development may
not achieve widespread market acceptance. We have recently begun to commercially
introduce our service for the delivery of streaming audio and video, and our
future revenue growth will depend, in part, on customer acceptance of this
service. Failure of our current and planned services to operate as expected
could delay or prevent their adoption. If our target customers do not adopt,
purchase and successfully deploy our current and planned services, our revenue
will not grow significantly and our business, results of operations and
financial condition will be seriously harmed. In addition, to the extent we
promote any portion of our technology as an industry standard by making it
readily available to users for little or no charge, we may not receive revenue
that might otherwise have been received by us.


  THE INTERNET CONTENT DELIVERY MARKET IS NEW AND OUR BUSINESS WILL SUFFER IF IT
DOES NOT DEVELOP AS WE EXPECT.

     The market for Internet content delivery services is new. We cannot be
certain that a viable market for our service will emerge or be sustainable. If
this market does not develop, or develops more slowly than we expect, our
business, results of operations and financial condition will be seriously
harmed.

  ANY FAILURE OF OUR NETWORK INFRASTRUCTURE COULD LEAD TO SIGNIFICANT COSTS AND
DISRUPTIONS WHICH COULD REDUCE OUR REVENUE AND HARM OUR BUSINESS, FINANCIAL
RESULTS AND REPUTATION.

     Our business is dependent on providing our customers with fast, efficient
and reliable Internet content delivery. To meet these customer requirements we
must protect our network infrastructure against damage from:

     - Human error;

     - Physical or electronic security breaches;

     - Fire, earthquake, flood and other natural disasters;

     - Power loss;

     - Sabotage and vandalism; and

     - Similar events.

                                        7
<PAGE>   10

     Despite precautions we have taken, the occurrence of a natural disaster or
other unanticipated problems at one or more of our servers could result in
service interruptions or significant damage to equipment. We provide a FreeFlow
service guarantee that our networks will deliver Internet content 24 hours a
day, seven days a week, 365 days a year. If we do not provide this service, the
customer does not pay for our services on that day. Any widespread loss of
services would reduce our revenue, and could harm our business, financial
results and reputation.

  BECAUSE OUR INTERNET CONTENT DELIVERY SERVICE IS COMPLEX AND IS DEPLOYED IN
COMPLEX ENVIRONMENTS, IT MAY HAVE ERRORS OR DEFECTS THAT COULD SERIOUSLY HARM
OUR BUSINESS.


     Our Internet content delivery service is highly complex and is designed to
be deployed in very large and complex networks. Because of the nature of our
service, we can only fully test it when it is fully deployed in very large
networks with high traffic. As of October 5, 1999, our network consisted of
1,475 servers. We and our customers have from time to time discovered errors and
defects in our software. In the future, there may be additional errors and
defects in our software that may adversely affect our service. If we are unable
to efficiently fix errors or other problems that may be identified, we could
experience:


     - Loss of or delay in revenue and loss of market share;

     - Loss of customers;

     - Failure to attract new customers or achieve market acceptance;

     - Diversion of development resources;

     - Loss of credibility;

     - Increased service costs; and

     - Legal actions by our customers.

  ANY FAILURE OF OUR TELECOMMUNICATIONS PROVIDERS TO PROVIDE REQUIRED
TRANSMISSION CAPACITY TO US COULD RESULT IN INTERRUPTIONS IN OUR SERVICE.

     Our operations are dependent upon transmission capacity provided by
third-party telecommunications providers. Any failure of such telecommunications
providers to provide the capacity we require may result in a reduction in, or
termination of, service to our customers. This failure may be a result of the
telecommunications providers or Internet service providers choosing services
that are competitive with our service, failing to comply with or terminating
their existing agreements with us or otherwise not entering into relationships
with us at all or on terms commercially acceptable to us. If we do not have
access to third-party transmission capacity, we could lose customers or fees
charged to such customers, and our business and financial results could suffer.

  THE MARKETS IN WHICH WE OPERATE ARE HIGHLY COMPETITIVE AND WE MAY BE UNABLE TO
COMPETE SUCCESSFULLY AGAINST NEW ENTRANTS AND ESTABLISHED COMPANIES WITH GREATER
RESOURCES.

     We compete in markets that are new, intensely competitive, highly
fragmented and rapidly changing. We have experienced and expect to continue to
experience increased competition. Many of our current competitors, as well as a
number of our potential competitors, have longer operating histories, greater
name recognition and substantially greater financial, technical and marketing
resources than we do. Some of our current or potential competitors have the
financial resources to withstand substantial price competition. Moreover, many
of our competitors have more extensive customer bases, broader customer
relationships and broader industry alliances that they could use to their
advantage in competitive situations, including relationships with many of our
current and potential customers. Our competitors may be able to respond more
quickly than we can to new or emerging technologies and changes in customer
requirements. Some of our current or potential competitors may bundle their
services with other software or hardware in a manner that may discourage Web
site owners from purchasing any service we offer or Internet service providers
from installing our servers.

                                        8
<PAGE>   11


     As competition in the Internet content delivery market continues to
intensify, new solutions will come to market. We are aware of other companies
that are focusing or may in the future focus significant resources on developing
and marketing products and services that will compete with Akamai. We also
believe that we may face competition from other providers of competing Internet
content delivery services, including networking hardware and software
manufacturers, content distribution providers, traditional hardware
manufacturers, telecommunications providers, software database companies, and
large diversified software and technology companies.


     Increased competition could result in:

     - Price and revenue reductions and lower profit margins;

     - Increased cost of service from telecommunications providers;

     - Loss of customers; and

     - Loss of market share.

Any one of these could materially and adversely affect our business, financial
condition and results of operations.

  A SIGNIFICANT DECLINE IN SALES TO APPLE COMPUTER COULD REDUCE OUR REVENUE AND
CAUSE OUR BUSINESS AND FINANCIAL RESULTS TO SUFFER.

     Sales of our service to Apple Computer represented approximately 75% of our
revenue for the six-month period ended June 30, 1999 and we expect that sales to
Apple Computer will represent a significant portion of our revenue for the year
ending December 31, 1999. Apple Computer has the right to terminate our
agreement on short notice if we materially breach our agreement. A significant
decline in sales to Apple Computer could reduce our revenue and cause our
business and financial results to suffer.

  IF ANY OF OUR STRATEGIC ALLIANCES TERMINATE, THEN OUR BUSINESS COULD BE
ADVERSELY AFFECTED.

     We entered into a strategic alliance with Apple Computer in June 1999, with
Cisco Systems in August 1999 and with Microsoft Corporation in September 1999.
Under each of these agreements, we are seeking to jointly develop technology,
services and/or products with our strategic alliance partners and we may not be
successful. The strategic alliance with Cisco may be terminated by Cisco or us
on short notice for any reason. The strategic alliance with Apple may be
terminated by Apple or us if the other party materially breaches the agreement
and the strategic alliance with Microsoft may be terminated by Microsoft or us
if the other party materially breaches the agreement. A termination of, or
significant adverse change in, our relationship with Apple Computer, Cisco
Systems or Microsoft could have a material adverse effect on our business.

  OUR BUSINESS WILL SUFFER IF WE ARE NOT ABLE TO SCALE OUR NETWORK AS DEMAND
INCREASES.

     We have had only limited deployment of our Internet content delivery
service to date, and we cannot be certain that our network can connect and
manage a substantially larger number of customers at high transmission speeds.
Our network may not be scalable to expected customer levels while maintaining
superior performance. In addition, as customers' usage of bandwidth increases,
we will need to make additional investments in our infrastructure to maintain
adequate downstream data transmission speeds. We cannot assure you that we will
be able to make these investments successfully or at an acceptable cost.
Upgrading our infrastructure may cause delays or failures in our network. As a
result, in the future our network may be unable to achieve or maintain a
sufficiently high transmission capacity. Our failure to achieve or maintain high
capacity data transmission could significantly reduce demand for our service,
reducing our revenue and causing our business and financial results to suffer.

                                        9
<PAGE>   12

  OUR BUSINESS WILL SUFFER IF WE DO NOT RESPOND RAPIDLY TO TECHNOLOGICAL
CHANGES.


     The market for Internet content delivery services is likely to be
characterized by rapid technological change, frequent new product and service
introductions and changes in customer requirements. We may be unable to respond
quickly or effectively to these developments. If competitors introduce products,
services or technologies that are better than ours or that gain greater market
acceptance, or if new industry standards emerge, our service may become
obsolete, which would materially and adversely affect our business, results of
operations and financial condition.



     In developing our service, we have made, and will continue to make,
assumptions about the standards that our customers and competitors may adopt. If
the standards adopted are different from those which we may now or in the future
promote or support, market acceptance of our service may be significantly
reduced or delayed and our business will be seriously harmed. In addition, the
introduction of services or products incorporating new technologies and the
emergence of new industry standards could render our existing service obsolete.


  IF OUR LICENSE AGREEMENT WITH MIT TERMINATES, THEN OUR BUSINESS COULD BE
ADVERSELY AFFECTED.

     We have licensed from MIT technology covered by various patent applications
and copyrights relating to Internet content delivery technology. Some of our
technology is based in part on the technology covered by these patent
applications and copyrights. MIT may terminate the license agreement if we cease
our business due to insolvency or if we materially breach the terms of the
license agreement. A termination of our license agreement with MIT could have a
material adverse effect on our business.

  OUR BUSINESS WILL BE ADVERSELY AFFECTED IF WE ARE UNABLE TO PROTECT OUR
INTELLECTUAL PROPERTY RIGHTS FROM THIRD-PARTY CHALLENGES.

     We rely on a combination of patent, copyright, trademark and trade secret
laws and restrictions on disclosure to protect our intellectual property rights.
These legal protections afford only limited protection; competitors may gain
access to our intellectual property which may result in the loss of our
customers.

     Although we have licensed technology covered by patent applications filed
with the United States Patent and Trademark Office with respect to Internet
content delivery services, we have no patents or patent applications with
respect to our Internet content delivery service. Accordingly, neither our
technology nor technology licensed by us is covered by patents that would
preclude or inhibit competitors from entering our market. Our future patents, if
any, and patents licensed by us may be successfully challenged or may not
provide us with any competitive advantages. Moreover, although we have licensed
technology covered by international patent applications, none of our technology
is patented abroad, nor do we currently have any international patent
applications pending. We cannot be certain that any pending or future patent
applications will be granted, that any future patent will not be challenged,
invalidated or circumvented, or that rights granted under any patent that may be
issued will provide competitive advantages to us. Monitoring unauthorized use of
our service is difficult and we cannot be certain that the steps we have taken
will prevent unauthorized use of our technology, particularly in foreign
countries where the laws may not protect our proprietary rights as fully as in
the United States.

  OUR FAILURE TO INCREASE OUR REVENUE WOULD PREVENT US FROM ACHIEVING AND
MAINTAINING PROFITABILITY.

     We have never been profitable. We have incurred significant losses since
inception and expect to continue to incur losses in the future. As of June 30,
1999, we had an accumulated deficit of $10.8 million. We cannot be certain that
our revenue will grow or that we will achieve sufficient revenue to achieve
profitability. Our failure to significantly increase our revenue would seriously
harm our business and operating results. We have large fixed expenses, and we
expect to continue to incur significant and increasing sales and marketing,
product development, administrative and other expenses, including fees to obtain
access to bandwidth for the transport of data over our network. As a result, we
will need to generate significantly higher revenues to achieve and maintain
profitability. If our revenue grows more slowly than we anticipate or if our
operating

                                       10
<PAGE>   13

expenses increase more than we expect or cannot be reduced in the event of lower
revenue, our business will be materially and adversely affected.

  THE LONG AND VARIABLE SALES CYCLES FOR OUR SERVICE MAY CAUSE REVENUE AND
OPERATING RESULTS TO VARY SIGNIFICANTLY FROM QUARTER TO QUARTER WHICH COULD
ADVERSELY AFFECT OUR STOCK PRICE.

     A customer's decision to purchase our Internet content delivery service
involves a lengthy evaluation and testing process. As a result, our sales cycle
is likely to be lengthy. Throughout the sales cycle, we spend considerable time
and expense educating and providing information to prospective customers about
the use and benefits of our service. Because of our limited operating history
and the nature of our business, we cannot predict these sales and deployment
cycles. The long sales cycles may cause our revenue and results of operations to
vary significantly and unexpectedly from quarter to quarter. If our operating
results fall below the expectations of securities analysts or investors in some
future quarter or quarters, the market price of our common stock could be
adversely affected.

  THE RATES WE CHARGE FOR OUR SERVICE MAY DECLINE OVER TIME WHICH WOULD REDUCE
OUR REVENUE AND COULD CAUSE OUR BUSINESS AND FINANCIAL RESULTS TO SUFFER.

     We expect that our cost to obtain bandwidth capacity for the transport of
data over our network will decline over time as a result of, among other things,
the large amount of capital currently being invested to build infrastructure
providing additional bandwidth. We expect the prices we charge for data
transported over our network will also decline over time as a result of, among
other things, the lower cost of obtaining bandwidth and existing and new
competition in the markets we address. As a result, our historical revenue rates
are not indicative of future revenue based on comparable traffic volumes. If we
fail to accurately predict the decline in costs of bandwidth or, in any event,
if we are unable to sell our service at acceptable prices relative to our
bandwidth costs, or if we fail to offer additional services from which we can
derive additional revenue, our revenue will decrease and our business and
financial results will suffer.

  OUR BUSINESS AND PROSPECTS DEPEND ON DEMAND FOR AND MARKET ACCEPTANCE OF THE
INTERNET AND ITS INFRASTRUCTURE DEVELOPMENT.

     The increased use of the Internet for retrieving, sharing and transferring
information among businesses, consumers, suppliers and partners has only begun
to develop in recent years, and our success will depend in large part on
continued growth in the use of the Internet. Critical issues concerning the
commercial use of the Internet, including security, reliability, cost, ease of
access, quality of service, regulatory initiatives and necessary increases in
bandwidth availability, remain unresolved and are likely to affect the
development of the market for our service. The adoption of the Internet for
information retrieval and exchange, commerce and communications generally will
require the acceptance of a new medium of conducting business and exchanging
information. Demand for and market acceptance of the Internet are subject to a
high level of uncertainty and are dependent on a number of factors, including:

     - The growth in consumer access to and acceptance of new interactive
       technologies;

     - The development of technologies that facilitate interactive communication
       between organizations; and

     - Increases in user bandwidth.

     If the Internet as a commercial or business medium fails to develop or
develops more slowly than expected, our business and prospects will suffer.

  OUR BUSINESS WILL SUFFER IF WE DO NOT ANTICIPATE AND MEET SPECIFIC CUSTOMER
REQUIREMENTS.

     Our current and prospective customers may require features and capabilities
that our current service offering does not have. To achieve market acceptance
for our service, we must effectively and timely anticipate and adapt to customer
requirements and offer services that meet customer demands. Our failure to offer
services that satisfy customer requirements would seriously harm our business,
results of operations and financial condition.

                                       11
<PAGE>   14

     We intend to continue to invest in technology development. The development
of new or enhanced services is a complex and uncertain process that requires the
accurate anticipation of technological and market trends. We may experience
design, manufacturing, marketing and other difficulties that could delay or
prevent the development, introduction or marketing of new services as well as
enhancements. The introduction of new or enhanced services also requires that we
manage the transition from older services in order to minimize disruption in
customer ordering patterns and ensure that we can deliver services to meet
anticipated customer demand. Our inability to effectively manage this transition
would materially adversely affect our business, results of operations and
financial condition.

  WE HAVE LIMITED SALES AND MARKETING EXPERIENCE; OUR BUSINESS WILL SUFFER IF WE
DO NOT EXPAND OUR DIRECT AND INDIRECT SALES ORGANIZATIONS AND OUR CUSTOMER
SERVICE AND SUPPORT OPERATIONS.

     We currently have limited sales and marketing experience. Our limited
experience may restrict our success in commercializing our service. Our service
requires a sophisticated sales effort targeted at a limited number of key people
within our prospective customers' organizations. This sales effort requires the
efforts of trained sales personnel. We need to expand our marketing and sales
organization in order to increase market awareness of our service to a greater
number of organizations and generate increased revenue. We are in the process of
developing our direct sales force and plan to hire additional qualified sales
personnel. Competition for these individuals is intense, and we might not be
able to hire the kind and number of sales personnel we need. In addition, we
believe that our future success is dependent upon our ability to establish
successful relationships with a variety of distribution partners. If we are
unable to expand our direct and indirect sales operations, we may not be able to
increase market awareness or sales of our service, which may prevent us from
achieving and maintaining profitability.

     Hiring personnel is very competitive in our industry because there is a
limited number of people available with the necessary technical skills and
understanding of our market. Once we hire them, they require extensive training
in our Internet content delivery service. If we are unable to expand our
customer service and support organization and train them as rapidly as
necessary, we may not be able to increase sales of our service, which would
seriously harm our business.

  OUR BUSINESS WILL SUFFER IF WE FAIL TO MANAGE OUR GROWTH PROPERLY.


     We have expanded our operations rapidly since our inception. We continue to
increase the scope of our operations and have grown our headcount substantially.
Our total number of employees grew from 35 on February 1, 1999 to 227 on
September 30, 1999. In addition, we plan to continue to hire a significant
number of employees this year. This growth has placed, and our anticipated
growth in future operations will continue to place, a significant strain on our
management systems and resources. Our ability to successfully offer our service
and implement our business plan in a rapidly evolving market requires an
effective planning and management process. We expect that we will need to
continue to improve our financial and managerial controls, reporting systems and
procedures, and will need to continue to expand, train and manage our work force
worldwide. Competition for highly skilled personnel is intense, especially in
the New England area. We may fail to attract, assimilate or retain qualified
personnel to fulfill our current or future needs. Our planned rapid growth
places a significant demand on management and financial and operational
resources. In order to grow and achieve future success, we must:


     - Retain existing personnel;

     - Hire, train, manage and retain additional qualified personnel; and

     - Effectively manage multiple relationships with our customers, suppliers
       and other third parties.

Failure to do so would have a materially adverse effect on our business, results
of operations and financial condition.

     We have recently hired and plan to hire in the near future a number of key
employees and officers. To integrate into our company, these individuals must
spend a significant amount of time learning our business model and management
system, in addition to performing their regular duties. Accordingly, the
integration of

                                       12
<PAGE>   15

new personnel has resulted and will continue to result in some disruption to our
ongoing operations. If we fail to complete this integration in an efficient
manner, our business and financial results will suffer.

  WE DEPEND ON OUR KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A RAPIDLY
CHANGING MARKET AND IF WE ARE UNABLE TO RETAIN OUR KEY EMPLOYEES, OUR ABILITY TO
COMPETE COULD BE HARMED.

     Our future success depends upon the continued services of our executive
officers and other key technology, sales, marketing and support personnel, who
have critical industry experience and relationships that we rely on in
implementing our business plan. None of our officers or key employees is bound
by an employment agreement for any specific term. We have "key person" life
insurance policies covering only the lives of F. Thomson Leighton and Daniel M.
Lewin. The loss of the services of any of our key employees could delay the
development and introduction of and negatively impact our ability to sell our
service. We face intense competition for qualified personnel, including research
and development, service and support and sales and marketing personnel.

  WE FACE RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS THAT COULD HARM OUR
BUSINESS.

     To be successful, we believe we must expand our international operations.
Therefore, we expect to commit significant resources to expand our international
sales and marketing activities. However, we may not be able to maintain or
increase market demand for our service which may harm our business. We are
increasingly subject to a number of risks associated with international business
activities which may increase our costs, lengthen our sales cycle and require
significant management attention. These risks include:

     - Increased expenses associated with marketing services in foreign
       countries;

     - General economic conditions in international markets;

     - Currency exchange rate fluctuations;

     - Unexpected changes in regulatory requirements resulting in unanticipated
       costs and delays;

     - Tariffs, export controls and other trade barriers;

     - Longer accounts receivable payment cycles and difficulties in collecting
       accounts receivable;

     - Potentially adverse tax consequences, including restrictions on the
       repatriation of earnings; and

     - The risks related to the recent global economic turbulence and adverse
       economic circumstances in Asia.

  WE FACE A NUMBER OF UNKNOWN RISKS ASSOCIATED WITH YEAR 2000 PROBLEMS.

     The year 2000 computer issue creates a variety of risks for us. The year
2000 computer problem refers to the potential for system and processing failures
of date-related data as a result of computer-controlled systems using two digits
rather than four to define the applicable year. For example, computer programs
that have time-sensitive software may recognize a date represented as "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculations causing disruptions of operations, including among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. The risks involve:

     - Potential warranty or other claims by our customers;

     - Errors in systems we use to run our business;

     - Errors in systems used by our suppliers;

     - Errors in systems used by our customers; and

     - Potential reduced spending by other companies on Internet content
       delivery services as a result of significant spending on year 2000
       remediation.

                                       13
<PAGE>   16

     We have designed our service for use in the year 2000 and beyond and
believe it will be year 2000 ready. However, our service is used in conjunction
with larger networks involving sophisticated hardware and software products
supplied by other vendors. Each of our customers' networks involves different
combinations of third-party products. We cannot evaluate whether all of their
products are year 2000 ready. We may face claims based on year 2000 problems in
other companies' products or based on issues arising from the integration of
multiple products within the overall network. Although no claims of this kind
have been made, we may in the future be required to defend our service in legal
proceedings which could be expensive regardless of the merits of these claims.

     If our suppliers, vendors, major distributors, partners, customers and
service providers fail to correct their year 2000 problems, these failures could
result in an interruption in, or a failure of, our normal business activities or
operations. If a year 2000 problem occurs, it may be difficult to determine
which party's products have caused the problem. These failures could interrupt
our operations and damage our relationships with our customers. Due to the
general uncertainty inherent in the year 2000 problem resulting from the
readiness of third-party suppliers and vendors, we are unable to determine at
this time whether year 2000 failures could harm our business and our financial
results.

     Our customers' purchasing plans could be affected by year 2000 issues if
they need to expend significant resources to fix their existing systems to
become year 2000 ready. This situation may reduce funds available to purchase
our service. In addition, some customers may wait to purchase our service until
after the year 2000, which may reduce our revenue.

RISKS RELATED TO LEGAL UNCERTAINTY

  WE COULD INCUR SUBSTANTIAL COSTS DEFENDING OUR INTELLECTUAL PROPERTY FROM
INFRINGEMENT OR A CLAIM OF INFRINGEMENT.

     Other companies, including our competitors, may obtain patents or other
proprietary rights that would prevent, limit or interfere with our ability to
make, use or sell our service. As a result, we may be found to infringe on the
proprietary rights of others. In the event of a successful claim of infringement
against us and our failure or inability to license the infringed technology, our
business and operating results would be significantly harmed. Companies in the
Internet market are increasingly bringing suits alleging infringement of their
proprietary rights, particularly patent rights. Any litigation or claims,
whether or not valid, could result in substantial costs and diversion of
resources. Intellectual property litigation or claims could force us to do one
or more of the following:

     - Cease selling, incorporating or using products or services that
       incorporate the challenged intellectual property;

     - Obtain a license from the holder of the infringed intellectual property
       right, which license may not be available on reasonable terms; and

     - Redesign products or services.

     If we are forced to take any of the foregoing actions, our business may be
seriously harmed. Although we carry general liability insurance, our insurance
may not cover potential claims of this type or may not be adequate to indemnify
us for all liability that may be imposed.

  INTERNET-RELATED LAWS COULD ADVERSELY AFFECT OUR BUSINESS.

     Laws and regulations which apply to communications and commerce over the
Internet are becoming more prevalent. The most recent session of the United
States Congress resulted in Internet laws regarding children's privacy,
copyrights, taxation and the transmission of sexually explicit material. The
European Union recently enacted its own privacy regulations, and is currently
considering copyright legislation that may extend the right of reproduction held
by copyright holders to include the right to make temporary copies for any
reason. The law of the Internet, however, remains largely unsettled, even in
areas where there has been some legislative action. It may take years to
determine whether and how existing laws such as those governing

                                       14
<PAGE>   17

intellectual property, privacy, libel and taxation apply to the Internet. In
addition, the growth and development of the market for online commerce may
prompt calls for more stringent consumer protection laws, both in the United
States and abroad, that may impose additional burdens on companies conducting
business online. The adoption or modification of laws or regulations relating to
the Internet, or interpretations of existing law, could adversely affect our
business.

  WE MAY BE SUBJECT TO REGULATION, TAXATION, ENFORCEMENT OR OTHER LIABILITIES IN
UNEXPECTED JURISDICTIONS.

     We provide our Internet content delivery service to customers located
throughout the United States and in several foreign countries. As a result, we
may be required to qualify to do business, or be subject to tax or other laws
and regulations, in these jurisdictions even if we do not have a physical
presence or employees or property in these jurisdictions. The application of
these multiple sets of laws and regulations is uncertain, but we could find we
are subject to regulation, taxation, enforcement or other liability in
unexpected ways, which could materially adversely affect our business, financial
condition and results of operations.

RISKS RELATED TO THE SECURITIES MARKETS AND THIS OFFERING


  OUR STOCK PRICE MAY BE VOLATILE WHICH COULD RESULT IN LITIGATION AGAINST
AKAMAI AND SUBSTANTIAL LOSSES FOR INVESTORS PURCHASING SHARES IN THIS OFFERING.



     Prior to this offering, you could not buy or sell our common stock
publicly. An active public market for our common stock may not develop or be
sustained after this offering. The market for technology stocks has been
extremely volatile. The following factors could cause the market price of our
common stock in the public market to fluctuate significantly from the price paid
by investors in this offering:


     - The addition or departure of key Akamai personnel;

     - Variations in our quarterly operating results;

     - Announcements by us or our competitors of significant contracts, new
       products or services offerings or enhancements, acquisitions,
       distribution partnerships, joint ventures or capital commitments;

     - Changes in financial estimates by securities analysts;

     - Our sales of common stock or other securities in the future;

     - Changes in market valuations of networking, Internet and
       telecommunications companies; and

     - Fluctuations in stock market prices and volumes.


     Volatility in the market price of our common stock may prevent investors
from being able to sell their common stock at or above our initial public
offering price.



     In the past, class action litigation has often been brought against
companies following periods of volatility in the market price of those
companies' common stock. We may become involved in this type of litigation in
the future. Litigation is often expensive and diverts management's attention and
resources which could materially adversely affect our business and results of
operations.


  MANAGEMENT MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT
INCREASE OUR PROFITS OR MARKET VALUE.

     Our management will have considerable discretion in the application of the
net proceeds of this offering, and you will not have the opportunity, as part of
your investment decision, to assess whether the proceeds are being used
appropriately. The net proceeds may be used for corporate purposes that do not
increase our profitability or our market value. Pending application of the
proceeds, they may be placed in investments that do not produce income or that
lose value.

                                       15
<PAGE>   18

  INSIDERS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL OVER AKAMAI AFTER THIS
OFFERING AND COULD LIMIT YOUR ABILITY TO INFLUENCE THE OUTCOME OF KEY
TRANSACTIONS, INCLUDING CHANGES OF CONTROL.


     We anticipate that the executive officers, directors and entities
affiliated with them will, in the aggregate, beneficially own approximately
64.2% of our outstanding common stock following the completion of this offering.
These stockholders, if acting together, would be able to influence significantly
all matters requiring approval by our stockholders, including the election of
directors and the approval of mergers or other business combination
transactions.


  PROVISIONS OF OUR CHARTER DOCUMENTS MAY HAVE ANTI-TAKEOVER EFFECTS THAT COULD
PREVENT A CHANGE IN CONTROL EVEN IF THE CHANGE IN CONTROL WOULD BE BENEFICIAL TO
OUR STOCKHOLDERS.

     Provisions of our amended and restated certificate of incorporation,
by-laws, and Delaware law could make it more difficult for a third party to
acquire us, even if doing so would be beneficial to our stockholders.

  THERE MAY BE SALES OF A SUBSTANTIAL AMOUNT OF OUR COMMON STOCK AFTER THIS
OFFERING THAT COULD CAUSE OUR STOCK PRICE TO FALL.

     Our current stockholders hold a substantial number of shares, which they
will be able to sell in the public market in the near future. Sales of a
substantial number of shares of our common stock within a short period of time
after this offering could cause our stock price to fall. In addition, the sale
of these shares could impair our ability to raise capital through the sale of
additional stock.

  THE UNPREDICTABILITY OF OUR QUARTERLY RESULTS MAY ADVERSELY AFFECT THE TRADING
PRICE OF OUR COMMON STOCK.

     Our revenue and operating results will vary significantly from quarter to
quarter due to a number of factors, many of which are outside of our control and
any of which may cause our stock price to fluctuate. The primary factors that
may affect us include the following:

     - Demand for Internet content delivery services;

     - The timing and size of sales of our services;

     - The timing of recognizing revenue and deferred revenue;

     - New product and service introductions and enhancements by our competitors
       and ourselves;

     - Changes in our pricing policies or the pricing policies of our
       competitors;

     - Our ability to develop, introduce and ship new products, services and
       enhancements that meet customer requirements in a timely manner;

     - The length of the sales cycle for our services;

     - Increases in the prices of, and availability of, the products, services,
       components or raw materials we purchase, including bandwidth;

     - Our ability to attain and maintain quality levels for our services;

     - Expenses related to testing of our services;

     - Costs related to acquisitions of technology or businesses; and

     - General economic conditions as well as those specific to the Internet and
       related industries.


     We plan to increase significantly our operating expenses to fund greater
levels of engineering and development, expand our sales and marketing
operations, broaden our customer support capabilities and continue to develop
new distribution channels. We also plan to expand our general and administrative
functions to address the increased reporting and other administrative demands,
which will result from this offering and the increasing size of our business.
Our operating expenses are largely based on anticipated revenue trends and a
high percentage of our expenses are, and will continue to be, fixed in the short
term. As a result, a delay in generating or recognizing revenue for the reasons
set forth above, or for any other reason, could cause significant variations in
our operating results from quarter to quarter and could result in substantial
operating losses.


                                       16
<PAGE>   19

     Due to the above factors, we believe that quarter-to-quarter comparisons of
our operating results are not a good indication of our future performance. It is
likely that in some future quarters, our operating results may be below the
expectations of public market analysts and investors. In this event, the price
of our common stock will probably fall.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements that involve
substantial risks and uncertainties. You can identify these statements by
forward-looking words such as "anticipate," "believe," "could," "estimate,"
"expect," "intend," "may," "should," "will" and "would" or similar words. You
should read statements that contain these words carefully because they discuss
our future expectations, contain projections of our future results of operations
or of our financial position or state other "forward-looking" information. We
believe that it is important to communicate our future expectations to our
investors. However, there may be events in the future that we are not able to
accurately predict or control. The factors listed above in the section captioned
"Risk Factors," as well as any cautionary language in this prospectus, provide
examples of risks, uncertainties and events that may cause our actual results to
differ materially from the expectations we describe in our forward-looking
statements. Before you invest in our common stock, you should be aware that the
occurrence of the events described in these risk factors and elsewhere in this
prospectus could have a material adverse effect on our business, results of
operations and financial position.

                                USE OF PROCEEDS


     We estimate that the net proceeds from our sale of the 8,000,000 shares of
common stock will be approximately $125.3 million, assuming an initial public
offering price of $17.00 per share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses payable by us. If the
over-allotment option is exercised in full, we estimate that the net proceeds
will be approximately $144.3 million.


     The principal purposes of this offering are to establish a public market
for our common stock, to increase our visibility in the marketplace, to
facilitate future access to public capital markets, to provide liquidity to
existing stockholders and to obtain additional working capital.

     We expect to use the net proceeds for anticipated working capital and
general corporate purposes. Although we may use a portion of the net proceeds to
acquire businesses, products or technologies that are complementary to our
business, we have no specific acquisitions planned. Pending such uses, we plan
to invest the net proceeds in investment grade, interest-bearing securities.

                                DIVIDEND POLICY

     We have never paid or declared any cash dividends on our common stock or
other securities and do not anticipate paying cash dividends in the foreseeable
future. We currently intend to retain all future earnings, if any, for use in
the operation of our business.

                                    DILUTION


     Akamai's pro forma net tangible book value as of June 30, 1999, giving
effect to the conversion of all shares of convertible preferred stock
outstanding as of June 30, 1999 into common stock on the closing of this
offering, was approximately $35.8 million, or $0.48 per share of common stock.
Pro forma net tangible book value per share represents our tangible net worth
(tangible assets less total liabilities) divided by the 75,301,004 shares of
common stock outstanding after giving effect to the conversion of all
outstanding shares of convertible preferred stock into common stock. After
giving effect to the issuance and sale of the shares of common stock offered by
Akamai in this offering at an assumed initial public offering price of $17.00
per share, Akamai's pro forma net tangible book value at June 30, 1999 would
have been $161.1 million, or $1.93 per share. The initial public offering price
per share will significantly exceed the net tangible book value per share.
Accordingly, new investors who purchase common stock in this offering will
suffer an immediate dilution of their investment of $15.07 per share. The
following table illustrates this per share dilution:

     The following table summarizes on a pro forma basis as of June 30, 1999,
giving effect to the conversion of all shares of convertible preferred stock
outstanding as of June 30, 1999 into common stock, the difference between the
number of shares of common stock purchased from Akamai, the total consideration
paid to Akamai, and the average price per share paid by existing stockholders
and by new investors. The calculation below is based on an assumed initial
public offering price of $17.00 per share, before deduction of estimated
underwriting discounts and commissions and estimated offering expenses payable

     The tables above assume no exercise of stock options and warrants
outstanding at June 30, 1999. As of June 30, 1999, there were options and
warrants outstanding to purchase 12,099,439 shares of common stock, including
908,339 shares of common stock issuable upon conversion of shares of Series C
convertible preferred stock, at a weighted average exercise price of $0.98 per
share and 12,731,261 shares reserved for future grant or award under Akamai's
stock plans. To the extent any of these options and warrants are exercised,
there will be further dilution to new investors. To the extent all of such
outstanding options and warrants had been exercised as of June 30, 1999, net
tangible book value per share after this offering would be $1.81 and total
dilution per share to new investors would be $15.19. If the underwriters'
over-allotment option is exercised in full, the number of shares held by new
investors will increase to 9,200,000 shares, or 10.9% of the total number of
shares of common stock outstanding after this offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion should be read together with our financial
statements and accompanying notes appearing elsewhere in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. Actual results may differ from those indicated in forward-looking
statements.

OVERVIEW

     We provide a global delivery service for Internet content that improves Web
site speed and reliability and protects against Web site crashes due to demand
overloads. Our FreeFlow service, which we market to large businesses and other
businesses with an Internet focus, delivers our customers' Web content through a
worldwide server network by locating the content geographically closer to their
users.

     Since our inception, we have incurred significant losses, and as of June
30, 1999, we had an accumulated deficit of $10.8 million. We have not achieved
profitability on a quarterly or an annual basis, and anticipate that we will
continue to incur net losses. We expect to incur significant engineering and
development and sales, general and administrative expenses and, as a result, we
will need to generate significant revenue to achieve and maintain profitability.

     We derive our revenue from the sale of our FreeFlow service under contracts
with terms typically ranging from three to 12 months. We recognize revenue based
on fees for the amount of Internet content delivered through our service. These
contracts also provide for minimum monthly fees. In the future, we may also
derive revenue from one-time implementation fees which would be recognized
ratably over the period of the related contracts.

     To date, substantially all of our revenue has been derived from customers
based in the United States. We expect that revenue from customers based outside
the United States will increase in future periods. To date, all of our revenue
has been derived from direct sales and we expect that revenue through indirect
distribution channels will increase in future periods. For the six-month period
ended June 30, 1999, Apple Computer accounted for 75% of our revenue and Yahoo!
accounted for 14% of our revenue.


     Cost of services consists of depreciation of network equipment used in
providing our FreeFlow service, fees paid to network providers for bandwidth and
monthly fees paid to third-party network data centers for housing our servers.
We enter into contracts for bandwidth with third-party network providers with
terms typically ranging from six months to three years. These contracts commit
us to minimum monthly fees plus additional fees for bandwidth usage above our
contracted level. Under our Akamai accelerated networks program, we provide use
of our servers to smaller Internet service providers which, in turn, provide us
with rack space for our servers and access to their bandwidth. We do not
recognize as revenue any value to the Internet service providers associated with
the use of our servers and do not expense the value of the rack space and
bandwidth we receive. We believe that to date the values provided under this
program have been insignificant.


     Engineering and development expenses consist primarily of salaries and
related personnel costs and costs related to the design, development, testing,
deployment and enhancement of our service and our network. We have to date
expensed our engineering and development costs as they were incurred. We believe
that research and development is critical to our strategic product development
objectives and intend to enhance our technology to meet the changing
requirements of the market demand. As a result, we expect our engineering and
development expenses to increase in the future.

     Sales, general and administrative expenses consist primarily of salaries
and related costs of sales and marketing, operations and finance personnel and
recruiting expenses, professional fees and legal and accounting services. We
expect that sales, general and administrative expenses will increase in the
future as we hire additional personnel, expand our operations domestically,
initiate additional marketing programs, establish sales offices in new locations
and incur additional costs related to the growth of our business and our
operations as a public company.

RESULTS OF OPERATIONS

PERIOD FROM INCEPTION (AUGUST 20, 1998) THROUGH DECEMBER 31, 1998 AND THE
SIX-MONTH PERIOD ENDED JUNE 30, 1999

     Revenue.  We recorded no revenue for the period from inception (August 20,
1998) to December 31, 1998. Revenue was $403,900 for the six months ended June
30, 1999. The increase in revenue was due to sales of our FreeFlow service,
which was commercially introduced in April 1999.

     Cost of Service.  Cost of service expenses were $30,600 for the period from
inception (August 20, 1998) to December 31, 1998 and represented 3.4% of total
operating expenses in fiscal 1998. Cost of service expenses were $1.4 million
for the six months ended June 30, 1999 and represented 14.0% of total operating
expenses for the six months ended June 30, 1999. The increase in cost of service
expenses was due to the commencement of testing of our FreeFlow service in early
1999 and commercial introduction of our FreeFlow service in April 1999.

     Engineering and Development.  Engineering and development expenses were
$228,600 for the period from inception (August 20, 1998) to December 31, 1998
and represented 25.4% of total operating expenses in fiscal 1998. Engineering
and development expenses for the six months ended June 30, 1999 were $2.1
million and represented 20.4% of total operating expenses for the six months
ended June 30, 1999. Approximately $1.5 million of the period-to-period increase
was attributable to personnel and payroll related expenses.

     Sales, General and Administrative.  Sales, general and administrative
expenses were $435,300 for the period from inception (August 20, 1998) to
December 31, 1998 and represented 48.4% of total operating expenses in fiscal
1998. Sales, general and administrative expenses for the six months ended June
30, 1999 were $5.2 million and represented 52.2% of total operating expenses for
the period. Approximately $1.8 million of the period-to-period increase was due
to sales, general and administrative personnel and payroll related expenses.
Approximately $1.5 million of the increase was attributable to an advertising
campaign.


     Equity Related Compensation.  Equity related compensation expenses consist
of the amortization of deferred stock compensation resulting from the grant of
stock options or shares of restricted stock at exercise or sale prices
subsequently deemed to be less than the fair value of the common stock on the
grant date. At June 30, 1999, deferred stock compensation, which is a component
of stockholders' equity, was $8.0 million. This amount is being amortized
ratably over the vesting periods of the applicable stock options and restricted
shares, typically four years, with 25% vesting on the first anniversary of the
grant date and the balance vesting 6.25% quarterly thereafter. We expect to
incur equity related compensation expense of at least $2.3 million in 1999, $2.9
million in 2000 and $2.6 million in 2001.



     Interest Income (Expense), Net.  Interest income (expense), net was $9,600
and $(144,000) for the period from inception (August 20, 1998) through December
31, 1998 and the six months ended June 30, 1999, respectively. Interest income
(expense), net consists of interest earned on our cash equivalent balances and
short-term investments, net of interest expense, and decreased during the six
months ended June 30, 1999 due to the issuance of the senior subordinated notes
and borrowings for the purchase of equipment.


NET OPERATING LOSSES AND TAX CREDIT CARRYFORWARDS.

     As of June 30, 1999, we had approximately $7.0 million of state and federal
net operating loss carryforwards for tax reporting purposes available to offset
future taxable income. Such net operating loss carryforwards begin to expire in
2019, to the extent that they are not utilized. We have not recognized any
benefit from the future use of loss carryforwards since inception. Management's
evaluation of all the available evidence in assessing realizability of the tax
benefits of such loss carryforwards indicates that the underlying assumptions of
future profitable operations contain risks that do not provide sufficient
assurance to recognize the tax benefits currently. The net operating loss
carryforwards could be limited in future years if there is a significant change
in our ownership.

                                       23

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, we have financed our operations primarily through private
sales of our capital stock and issuance of senior subordinated notes totaling
approximately $55.9 million in net proceeds through June 30, 1999. We have also
financed our operations through borrowings on long-term debt agreements for the
purchase of capital equipment in the amount of $1.5 million. At June 30, 1999,
cash, cash equivalents and short-term investments totaled $45.1 million.

     Cash provided by (used in) operating activities was $1,600 for the period
from inception (August 20, 1998) to December 31, 1998 and $(5.4) million for the
six months ended June 30, 1999. Net cash flows from operating activities in each
period reflect increasing net losses and to a lesser extent receivables and
prepaid expenses offset in part by increased accounts payable and accrued
expenses.

     Cash used in investing activities was $1.7 million for the period from
inception (August 20, 1998) to December 31, 1998 and $5.3 million for the six
months ended June 30, 1999. Net cash used for investing activities in each
period reflect purchases of property and equipment, primarily computers and
servers for deployment and expansion of our network.

     Cash provided by financing activities was $8.3 million for the period from
inception (August 20, 1998) through December 31, 1998 and $48.9 million for the
six months ended June 30, 1999. Cash provided by financing activities for these
periods was derived primarily from private sales of convertible preferred stock
and the issuance of 15% senior subordinated notes. We have an equipment line of
credit aggregating $1.5 million, collateralized by the property and equipment
which bears interest at the current 36 month treasury yield plus 275 basis
points, with a minimum interest rate of 7.0%. At June 30, 1999, approximately
$1.5 million was outstanding under this line of credit.

     We believe that the net proceeds from this offering, together with our
current cash, cash equivalents and marketable securities, will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
at least the next 12 months. If cash generated from operations is insufficient
to satisfy our liquidity requirements, we may seek to sell additional equity or
debt securities. If additional funds are raised through the issuance of debt
securities, these securities could have rights, preferences and privileges
senior to those accruing to holders of common stock, and the term of this debt
could impose restrictions on our operations. The sale of additional equity or
convertible debt securities could result in additional dilution to our
stockholders, and we cannot be certain that additional financing will be
available in amounts or on terms acceptable to us, if at all. If we are unable
to obtain this additional financing, we may be required to reduce the scope of
our planned technology, services or product development and sales and marketing
efforts, which could harm our business, financial condition and operating
results.

YEAR 2000 READINESS

     Impact of Year 2000 Computer Problem.  The year 2000 computer problem
refers to the potential for system and processing failures of date-related data
as a result of computer-controlled systems using two digits rather than four to
define the applicable year. For example, computer programs that have
time-sensitive software may recognize a date represented as "00" as the year
1900 rather than the year 2000. This could result in a system failure or
miscalculation causing disruptions of operations, including among other things,
a temporary inability to process transactions, send invoices or engage in
similar normal business activities.

     State of Readiness of our Service.  We have designed our network and our
service for use in the year 2000 and beyond and believe our network and service
are year 2000 ready. We are in the process of testing our network and our
service for year 2000 compliance and plan to complete this testing before
November 1999. To date, our tests of our service and our networks have not
revealed any significant year 2000 problems. Our network is generally integrated
into larger networks involving sophisticated hardware and software products
supplied by other vendors. Each of our customers' networks involves different
combinations of third party products. We cannot fully evaluate whether all of
their products are year 2000 ready. We may face claims based on year 2000
problems in other companies' products or based on issues arising from the
integration of multiple products within the overall network. Although no such
claims have been made against us, we may in

                                       24
<PAGE>   27

the future be required to defend our service in legal proceedings which could be
expensive regardless of the merits of such claims.

     State of Readiness of our Internal Systems.  Our business may be affected
by year 2000 issues related to noncompliant internal systems developed by us or
by third-party vendors. Our material third-party vendors have stated that they
are, or expect to be, year 2000 ready in a timely manner. We are not currently
aware of any material year 2000 problem relating to any of our material internal
systems. We are in the process of testing all such systems for year 2000
readiness and plan to complete this testing before November 1999. We are not
aware of any significant systems that contain embedded chips that are not year
2000 compliant. Our internal operations and business are also dependent upon the
computer-controlled systems of third parties such as our suppliers, customers
and other service providers. We believe that, absent a systemic failure outside
our control, such as a prolonged loss of electrical or telecommunications
service, year 2000 problems at third parties such as manufacturers, suppliers,
customers and service providers will not have a material impact on our
operations. If our manufacturers, suppliers, vendors, partners, customers and
service providers fail to correct their year 2000 problems, these failures could
result in an interruption in, or a failure of, our normal business activities
and services. If a year 2000 problem occurs, it may be difficult to determine
which party's products have caused the problem. These failures could interrupt
our operations and damage our relationships with our customers. Due to the
general uncertainly inherent in the year 2000 problem resulting from the
readiness of third-party manufacturers, suppliers and vendors, we are unable to
determine at this time whether year 2000 failures could harm our business and
our financial results. Our customers' purchasing plans could be affected by year
2000 issues if they need to expend significant resources of fix their existing
systems to become year 2000 ready. This situation may reduce funds available to
purchase our service.

     Risks.  The failure of our internal systems to be year 2000 ready could
temporarily prevent us from providing service to our customers, issuing invoices
and developing products and services and could require us to devote significant
resources to correct such problems. Due to the general uncertainty inherent in
the year 2000 computer problem, which results from the uncertainty of the year
2000 readiness of third-party suppliers and vendors, we are unable to determine
at this time whether the consequences of year 2000 failures will have a material
impact on our business, results of operations or financial condition.

     Contingency Plan.  We have not yet fully developed a contingency plan to
address all situations that may result if we experience significant year 2000
problems. We expect to complete this contingency plan later this year. As part
of our contingency plan, we intend to maintain a fully operational back-up site
and conduct network monitoring 24 hours per day during the transition period
from 1999 to 2000. Our back-up site will be located at one of our server sites
and be equipped with power generation and communication alternatives.

     To date, we have incurred expenses of approximately $250,000 in connection
with our efforts to become year 2000 ready. We believe that our total expenses
for year 2000 readiness will be approximately $350,000.

MARKET RISK

     Akamai does not use derivative financial instruments. We generally place
our marketable security investments in high credit quality instruments,
primarily U.S. Government obligations and corporate obligations with contractual
maturities of less than one year. We do not expect any material loss from our
marketable security investments and therefore believe that our potential
interest rate exposure is not material.

RECENT ACCOUNTING PRONOUNCEMENT

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivatives and Hedging Activities," which establishes
accounting and reporting standards for derivative instruments, including
derivative instruments embedded in other contracts, and for hedging activities.
We will adopt SFAS No. 133 as required by SFAS No. 137, "Deferral of the
Effective Date of the FASB Statement No. 133," in fiscal year 2001. We do not
expect the adoption of SFAS No. 133 to have an impact on our financial condition
or results of operations.

OVERVIEW

     We provide a global delivery service for Internet content that improves Web
site speed and reliability and protects against Web site crashes due to demand
overloads. Our FreeFlow service, which we market to large businesses and other
businesses with an Internet focus, delivers our customers' Web content through a
worldwide server network by locating the content geographically closer to their
users. Using software that is based on our proprietary mathematical formulas, or
algorithms, we monitor Internet traffic patterns and deliver our customers'
content by the most efficient route available. Our service is easy to implement
and does not require our customers or their Web site visitors to make any
hardware or software modifications. Using our FreeFlow service, our customers
have been able to more than double the speed at which they deliver content to
their users and, in some instances, have been able to improve speeds by ten
times or more.


     Our technology originated from research that our founders began developing
at the Massachusetts Institute of Technology in 1995. We introduced our FreeFlow
service commercially in April 1999. As of October 5, 1999, we had 1,475 Akamai
servers deployed in 24 countries across 55 telecommunications networks,
providing our customers with a guaranteed global Internet content delivery
service. Our customers, which operate many highly trafficked Web sites, include
Apple Computer, CNN Interactive, Discovery Channel Online, Infoseek Corp., J.
Crew.com, The Motley Fool and Yahoo!.


INDUSTRY BACKGROUND

     The Internet has emerged as a global medium for commerce and
communications. International Data Corporation estimates that there were
approximately 142 million users of the Internet at the end of 1998 and that the
number of users will grow to 502 million by the end of 2002. The growth in the
number of users, together with the wealth of content and information available
on the Internet, have led to sharp increases in the daily traffic volume of Web
sites. Media Metrix estimated that the number of unique visitors to the top 25
Web sites increased from 224 million in June 1998 to 330 million in June 1999.

     The ability of a Web site to attract users is in part based on the richness
of its content. Increasingly, Web site owners want to enhance their content by
adding graphics, such as photographs, images and logos, as well as deploying
newer technologies, such as video and audio streaming, animation and software
downloads. While richer content attracts more visitors, it also places
increasing demands on the Web site to deliver the content quickly and reliably.
As a result, Web site owners frequently elect to constrain the amount of rich
content on their Web sites, thus sacrificing the quality of the user experience
to maintain minimally acceptable performance levels.

     The Internet was not originally designed to provide a rich multimedia
environment for individual Web site visitors. Since its origins as a United
States Department of Defense research project, the Internet has evolved into an
aggregation of many networks, each developed and managed by different
telecommunications service providers. As a result, the Internet, unaided, lacks
the ability to manage traffic between disparate networks to find the optimal
route to deliver content. Congestion or transmission blockages significantly
delay the information reaching the user. The storage of Web site information in
central locations further complicates Internet content delivery. As the volume
of information requested on a Web site increases, large quantities of repetitive
data traverse the Internet from that central location.

     The combination of richer content and increasing volumes of Web site
visitors can lengthen significantly the time required for a user to download
information from a site and may cause the site to crash. These performance
problems are exacerbated during peak demand times, such as a breaking news
event, the release of an on-line movie trailer, the first day of ticket sales
for a hit film, an on-line special event or sudden demand for a new software
release. Because it is typically not cost-effective for a Web site to design its
infrastructure to handle relatively infrequent periods of "flash" or sudden
demand, periods of peak network traffic and surges in traffic volumes often
overwhelm the capacity of the site, causing long delays or complete site
outages. Delays and site crashes often cause user frustration and
disappointment. Jupiter Communications found that in

                                       26
<PAGE>   29

June 1999, if response times at a particular Web site did not meet Internet
users' expectations, 37% of those users visited a substitute Web site to meet
their needs.

     While various products and services have been developed to address
performance problems, they generally do not address the fundamental
architectural limitations of the Internet. For example, caching is a hardware
and/or software solution sold to Internet service providers to help them improve
network performance by placing electronic copies of selected Internet content on
geographically distributed servers on their own network. Caching is not,
however, designed to address the needs of Web site owners, and in particular to
deliver their content with high performance and reliability across the multiple
networks that comprise the Internet. Outsourcing Web server management to
hosting companies enables Web sites to add server capacity as needed and
increase server reliability. However, hosting does not address the transmission
disruption problems that can arise as data leave the hosting company's servers
and traverse the public network to the user. Broadband services are being
deployed to increase the speed of a user's connection to the Internet,
addressing the problems that occur in what is commonly known as the "last mile."
While these services increase bandwidth in the last mile, they do not address
the content delivery problems that occur when congestion overwhelms a Web site
or specific points across the Internet.

     To serve the increasing volumes of traffic on the Internet and, at the same
time, enhance the user experience with increased graphic, video and audio
content, Web sites require content delivery services that can provide rich
content to users, enhance Web site response times and avoid delays and outages
caused by peak demand and public network congestion. These services must be not
only fast, reliable and easy to implement, but also capable of delivering rich
content that is continually updated. In addition, these services may be
cost-effective to the customer only if they do not require significant capital
or labor expenditures and can be implemented at a cost that is based on actual
usage.

THE AKAMAI SOLUTION


     Akamai provides a content delivery service that allows Web sites to
accelerate the delivery of rich content to Internet users, improve reliability
and handle peak crowds. To use our service, customers identify and tag portions
of their Web site content that require significant amounts of bandwidth, such as
advertising banners, icons, graphics, video and audio streaming and software
downloads. These tagged items are delivered over our server network. When users
request this content, which we call "Akamaized" content, our FreeFlow service
routes the request to the server that is best able to deliver the content most
quickly based on the geographic proximity, performance and congestion of all
available servers on our network. Our network has the following capabilities:


     - Real-time Internet monitoring, which enables our servers to monitor in
       real-time the performance of our network and communicate the information
       to other servers in our network;

     - Dynamic server load management, which enables each server to react to
       Internet and server congestion, overloads and outages and respond by
       rerouting traffic around problems; and

     - Internet user connection management, which enables each server to map the
       geographic location of users so that content is delivered to each user
       from our most efficient server.

These capabilities enable our global network to provide delivery of Web content
through the optimal route without relying on any central point of control.

     The key benefits of our solution include:

     Faster Content Delivery.  FreeFlow can more than double the speed at which
Web sites can deliver Web content to Internet users and, in some cases, has
improved speeds by ten times or more. In addition, by using our service,
customers can deliver more graphics, video, audio, animation, software downloads
and other rich content without compromising the performance of their Web sites.
The ability to improve the speed of a Web site and increase the use of rich
content can result in an enhanced user experience and longer Web site visits,
which can translate into greater advertising and e-commerce revenue for our
customers.

                                       27
<PAGE>   30

     Superior Reliability.  The underlying technology in our FreeFlow service
enables us to monitor the performance of our global network 24 hours a day,
seven days a week, 365 days a year. We route traffic around network bottlenecks
or outages, delivering content in an optimal manner while avoiding delays and
downtime.

     Peak Demand Protection.  Traditional Web site architectures support a
finite number of users. It is costly to upgrade Web sites to accommodate
sporadic peak demand. Our service enables a customer to use the extensive
capacity of our global server network and thus eliminate the need for a Web site
to incur significant capital or labor expenditures to design an infrastructure
to handle peak demand.


     Global Reach.  We have implemented our service on our global network of
over 1,475 servers deployed in 24 countries across 55 telecommunications
networks.


     Compelling Cost Proposition.  Our customers can use our service without any
up-front investment in hardware or software. We offer our service under
pay-for-use contracts based on the amount of Internet content delivered. To
further reduce costs, our customers receive volume discounts as their usage
increases. We thus provide our customers with a scalable approach to content
delivery without the capital investment and increasing cost per user typically
associated with equipment-based alternatives.


     Ease of Implementation and Compatibility.  Our service forms a transparent
layer on the Internet between our customer's Web site and visitors accessing
that site. Through our easy-to-use FreeFlow Launcher software, our customers can
quickly tag the objects to be delivered over our network and begin to implement
our service. Customers can continuously update or modify their Web site content
without affecting site performance. Moreover, our service does not require that
the customer modify its computer hardware or software.


STRATEGY


     Our goal is to capitalize on our proprietary technology and leading market
position to establish a new industry standard for the delivery of all types of
Web content and applications to Internet users. To accomplish this goal, we are
pursuing a strategy built on the following initiatives:



     Target Leading Web Sites Across a Broad Spectrum of Internet
Categories.  We commercially introduced our FreeFlow service in April 1999 and
have attracted as customers three of the world's top six most heavily trafficked
Web sites, as reported by Media Metrix for June 1999. We are seeking to further
extend our penetration into leading Web sites across a broad spectrum of
Internet categories, including media, entertainment, financial services and
e-commerce. We are expanding our direct sales force to target Web sites in these
categories. We introduced a program designed for the resale of our FreeFlow
service by qualified resellers such as major Internet hosting providers. We are
also developing partner programs with companies that have influence with Web
site owners, such as Web design firms and systems integrators who can promote
our service to their customers.



     Further Expand and Enhance Our Worldwide Network.  We plan to continue to
expand our network to increase capacity and improve performance. By adding
servers, we can increase the number of routes through which we can deliver Web
content and thus shorten the distance between our servers and Internet users. We
have a three-part strategy for expanding our network. First, we are placing our
servers in secure data centers served by Internet service providers that provide
us with bandwidth to deliver content from our servers to Internet users. Second,
through our Akamai accelerated networks program, we provide use of our servers
to smaller Internet service providers who, in turn, provide us with rack space
for our servers and bandwidth to deliver content. Finally, we are enhancing our
network by integrating our technology with network infrastructure products such
as routers, switches and caches, to facilitate implementation of our service by
Internet service providers.



     Establish Akamai as a Leading Brand for Content Delivery.  We plan to
establish Akamai as the industry standard for providing Internet content
delivery. We intend to promote our brand to create strong penetration among all
top Internet content providers. We believe that this strong brand awareness,
combined with our existing global network of servers and customer base of
leading companies with an Internet focus, will help to create a competitive
advantage in our market.

                                       28
<PAGE>   31


     Extend Our World-Class Technology Leadership.  We believe that Akamai has
established a reputation as a technological leader in Internet content delivery.
We plan to continue to enhance our current technologies, and develop new
technologies, that can improve the performance and reliability of our network
and expand the features and benefits that we can offer through our service. We
intend to leverage our technology to introduce innovative services and products
that take advantage of our worldwide network and our distributed computing
services capacity. To maintain our technological leadership, we plan to continue
to invest significant time and resources in recruiting computer scientists,
engineers and software developers with expertise in the areas of mathematics,
computer science and networking. We also plan to actively participate in the
development and promotion of Internet industry standards.


     Leverage Our Services Model.  We are creating a business model that will
generate a stream of recurring revenues, while maintaining relatively low
capital and bandwidth costs. We believe that we can maintain relatively low
capital costs because our service is based on software that runs on low cost,
off-the-shelf servers and we use the existing network infrastructure of
telecommunications providers instead of building our own fiber- or
satellite-based network infrastructure. In addition, we believe that we can
maintain relatively low bandwidth costs because we buy in large volumes and our
costs are based primarily on usage levels. Our recurring revenue model is based
on offering services to our customers that provide for payment based on the
amount of Internet content delivered through our service. As a result, our
revenue base has the potential to grow as the number of Internet users
increases, as these users access the Internet more often and for longer periods,
and as more Web sites incorporate richer content. We believe that the relatively
low capital costs required to build and maintain our network, together with the
relatively low costs that we are required to pay for bandwidth used on our
network, should enable us to leverage this recurring revenue base.


     Build Strategic Alliances to Strengthen Market Position.  We intend to
continue to develop strategic alliances with other Internet-related companies to
accelerate market acceptance of our services and expand and enhance our global
network. To date, we have entered into three major strategic alliances. In June
1999, we entered into a strategic alliance with Apple Computer to integrate
Apple's QuickTime TV network, QuickTime 4 Player and QuickTime Streaming Server
with our global Internet content delivery service. In August 1999, we entered
into a strategic alliance with Cisco Systems to, among other things, integrate
Akamai technology with Cisco's networking products. In September 1999, we
entered into a strategic alliance with Microsoft Corporation to, among other
things, integrate Microsoft's streaming media and Windows Server operating
systems technologies into the Akamai network. We will continue to pursue select
relationships with other Internet technology providers, Internet hosting
companies, Internet service providers, network providers, Web site developers
and systems integrators. We believe these relationships will accelerate the
proliferation of our technology and services, increase our brand recognition and
improve access to our target customer base.


FREEFLOW SERVICE


  SERVICES



     Our FreeFlow service provides for the delivery of Web site content to
Internet users. When implementing our FreeFlow service, our customers select
bandwidth intensive portions of their Web sites, such as complex graphics,
advertisements, logos, software downloads and pictures, which are delivered to
users over our network. FreeFlow service customers pay only for the Internet
content delivered through our service. Monthly usage charges are based on
megabits per second of content delivered. Customers commit to pay for a minimum
usage level over a fixed contract term, and pay additional fees when usage
exceeds this commitment. Monthly prices currently begin at $1,995 per megabit
per second, with discounts available for volume usage.



     This FreeFlow service is backed by a proof-of-performance guarantee.
Through our guarantee we promise that:


     - Our service will be available to deliver content 24 hours a day, seven
       days a week, 365 days a year;

     - Our service will deliver content faster than the customer can do it
       without our service;

                                       29
<PAGE>   32

     - If we fail to deliver on either of these two promises on any day, the
       customer does not pay for the service for that day.


     We have recently begun to introduce a commercial service that enables the
delivery of streaming audio and video over our network.


  TECHNOLOGY

     The FreeFlow service incorporates the following Akamai technologies:

     Akamaized URLs.  Akamai's technology changes the way in which content on a
Web page is delivered to an Internet user without interrupting the normal data
flow. Normally, when a user clicks on any Web page, the Web site returns a
Hypertext Markup Language, or HTML, text file containing text and formatting
instructions which the browser uses to display the page. This text file also
contains the Universal Resource Locators, or URLs, of non-text objects on the
page, such as photographs, banner advertisements, graphics and software
downloads.

     Akamai's customers identify which of their Web objects are to be delivered
over Akamai's network. The customer then runs a software utility provided by
Akamai, called FreeFlow Launcher, which searches for the URLs of the selected
objects and tags them with a special code. We refer to this tagged content as
"Akamaized" content. This modification transforms each URL for Akamaized content
into an "ARL," or Akamai Resource Locator. The result is that when a user's
browser downloads an HTML file containing ARLs of Web objects for that page, the
browser is automatically pointed to Akamai's network to retrieve those objects.
Our process does not require any modification to the browser or other personal
computer configuration changes. While Akamai can serve the HTML as well as the
objects embedded in it, our customers typically choose to serve the HTML
themselves to maintain direct contact with the user. Thus, even while users are
receiving Akamaized content from our servers, our customers can continue to
count Web site visitors, track user demographics and dynamically assemble Web
page content, including the insertion of targeted advertising and other
personalized content.

     Domain Name Servers.  The Internet relies on a distributed hierarchical
database, called the Domain Name System, or DNS, to translate Web site names
into numerical Internet Protocol, or IP, addresses. Akamai employs tiers of DNS,
or name, servers that interact seamlessly with the Internet's standard DNS
servers and intelligently direct a user's request for Web site content toward
the most efficient Akamai server to deliver the requested content. When an
Internet user requests a page containing Akamaized content, the user's browser
asks a Domain Name Server to find an IP address for the Akamai network. The DNS
automatically directs the query to one of Akamai's top-level DNS servers rather
than to the central Web site. The Akamai top-level DNS servers use proprietary
mapping software to determine the approximate location of the user in the
Internet. The top-level DNS server then refers the user's request to an Akamai
low-level DNS server that is responsible for traffic near the user. The
low-level DNS server then answers with the IP addresses of a group, or "region,"
of Akamai servers that can deliver the desired content to the user most quickly
and reliably based on the geographic proximity, load and availability of all
servers on the network. The low-level DNS servers use up-to-the-second
information about Internet and server conditions to make the best routing
decision for each user.

     Server Load Management.  Once Akamai's servers determine the optimal region
for serving content to a user at a given moment, a simple process for selecting
an individual server for such delivery would be to "round-robin" all requests to
each content server in that region. However, such an approach would require that
all objects reside on every content server, resulting in poor use of system
resources and poor load balancing. Instead, Akamai uses proprietary algorithms
to balance the loads of all servers within each region and ensure that objects
reside in the minimum number of servers required to deliver optimal performance.

     Real-Time Monitoring.  Akamai's FreeFlow service performs real-time
monitoring of its own servers and of the Internet to make certain that content
is delivered to users with the best performance and reliability. A key design
principle of Akamai's system is the use of distributed control. Therefore, if
any computer, data center or portion of the Internet fails, the FreeFlow service
will continue operating.

                                       30
<PAGE>   33

     FreeFlow constantly monitors the performance of connections between various
locations around the Internet and our regions. We use numerous types of network
information to determine the performance of these connections. The result is a
"map" of the optimal Akamai region for each location at that point in time.
Akamai rebuilds this map periodically to reflect changing conditions.

     Real-time monitoring also ensures reliability. A region is suspended if the
data center in which Akamai's servers are located fails or is performing poorly.
However, even when this disruption occurs, the FreeFlow service continues to
function. To ensure fault tolerance, Akamai deploys back-up low-level DNS
servers in each region that physically reside in separate data centers. These
back-up DNS servers automatically direct users to servers in alternate regions
unaffected by the remote outage.

     To ensure reliability against the failure of an individual server, each
server is assigned a "buddy" server within a region. Buddy servers query one
another every second to sense all failures. If a server's buddy does not respond
to a query, that server takes over its buddy's IP address and serves all content
requested of the buddy.

STRATEGIC ALLIANCES


     We have strategic alliances with Apple Computer, Cisco Systems and
Microsoft Corporation and intend to enter into additional strategic alliances
with leading technology companies to accelerate market acceptance of our
services and to expand and enhance our global network. We believe strategic
alliances can accelerate market acceptance of our technology and services,
increase our brand recognition and improve access to our target customer base.


  APPLE COMPUTER

     In June 1999, we entered into a strategic alliance with Apple Computer to
improve the delivery of streaming media over the Internet. Under the agreement,
we will integrate our global Internet content delivery service and Apple's
QuickTime TV network, QuickTime 4 Player and QuickTime Streaming Server. The
combined technologies are designed to give Apple Macintosh and Microsoft Windows
users worldwide access to fast, reliable, high-resolution streaming services
through e-commerce, media and other Web sites.

     Under the terms of the strategic alliance, Apple has purchased our FreeFlow
service and we have agreed to be the exclusive network provider to Apple for
QuickTime TV. We have also agreed to cause our network to meet minimum capacity
levels to support streaming media. Apple has also designated us as the preferred
network provider to Apple customers developing streaming QuickTime content.

     Apple purchased shares of our Series D convertible preferred stock for an
aggregate purchase price of approximately $12.5 million in June 1999.

  CISCO SYSTEMS

     In August 1999, we entered into a strategic alliance with Cisco Systems to
enhance and jointly develop new content routing, switching and caching
technologies to improve the performance of Internet content delivery. Under the
strategic alliance, Cisco and Akamai have agreed to jointly develop protocols
and algorithms designed to enhance content-based routing and switching
technologies within Cisco's infrastructure to optimize our Internet content
delivery service. In addition, Cisco has agreed to integrate our Internet
content delivery technology into its networking technology. We have also agreed
to explore new technologies to enable next-generation switching designed to
dynamically adapt to changing network conditions. Under the agreement, each of
Akamai and Cisco has also agreed to joint marketing arrangements, including the
promotion to its customers of the use of the other's products and services,
whenever commercially reasonable.

     Cisco purchased shares of our Series E convertible preferred stock for an
aggregate purchase price of approximately $49.0 million in August 1999.

                                       31

  MICROSOFT CORPORATION


     In September 1999, we entered into a strategic alliance with Microsoft
Corporation to integrate Microsoft technologies into the Akamai network. As part
of the agreement, we intend to integrate Microsoft Windows Media(TM)
technologies with our global Internet content delivery service, and we will
create a version of our software to support our FreeFlow service that works on
Microsoft Windows Server operating systems. In addition, Microsoft's Streaming
Media Division has agreed to become one of our Internet content delivery service
customers.


     Under the terms of our agreement with Microsoft, we have agreed to modify
our server software to operate on the Microsoft Windows Server operating systems
platform and to support Microsoft's streaming media format. In addition, we will
explore with Microsoft other possible integration and support opportunities.

     Microsoft purchased shares of our Series F convertible preferred stock for
an aggregate purchase price of approximately $15.0 million in September 1999.

CUSTOMERS

     We introduced our FreeFlow service commercially in April 1999. Our customer
base spans a broad spectrum of Internet categories. The following is a
representative list of our customers.

     As a leading Web directory, LookSmart provides search results across more
than 1 million unique URLs and over 70,000 individual categories. Looksmart is
dedicated to improving Web site performance and views Akamai as a major
contributor in this area. Since June 1999, the average download time for a
typical LookSmart Web page has been cut in half. LookSmart, which has now
implemented Akamai's service, relies on us as a key component for maintaining
Web site speed and reliability for its growing end user base.


  THE MOTLEY FOOL



     The Motley Fool is a leading online forum designed to give to readers
financial advice that they can understand and to discuss ways to make investment
and personal financial decisions. The Motley Fool has been using our service
since May 1999 and has experienced faster Web download times for its customers
based on a report by Keynote Systems. The Motley Fool is aimed at educating,
amusing and enriching the individual investor, has been able to off load
approximately 90% of its site's content to the servers from Akamai's network. In
the month of August 1999, Akamai served 260 million hits for The Motley Fool's
Web site enabling the Web site to decrease its bandwidth requirements on
servers, switches, load balancers and routers.


SALES, SERVICE AND MARKETING


     We currently sell our service primarily through a direct sales force. Our
plan is to continue to pursue heavily trafficked Web sites through our direct
sales force and to penetrate other markets through our reseller program and
other indirect distribution channels. As of September 30, 1999, we had 65
employees in our sales and distribution organization, of whom 19 are in direct
sales. Currently our sales force is actively targeting primarily domestic
companies, focusing on the 300 Web sites that have the greatest number of
visitors, Fortune 100 companies and other companies with large operations in the
United States.



     In addition to our direct sales efforts, we are developing our partner
program with design and system integration firms and consultants. We encourage
these partners to recommend the Akamai solution to their customers as part of
their design, integration and consulting work for those customers. As of
September 30, 1999, we had four employees in our partner program group and one
employee in our reseller program group.



     Our technical consulting group directly supports our sales and distribution
efforts by providing technical consulting and integration assistance to our
current and prospective customers. As of September 30, 1999, we had 22 employees
in our technical consulting group.



     We believe that a high level of customer service and support is critical to
the successful marketing and sale of our products and services. We are building
a comprehensive service and support organization to meet the needs of our
customers. As of September 30, 1999, we had seven employees in our customer
service and support organization and 12 employees in our account management
organization. We are seeking to hire additional customer service and support
personnel as our customer base grows and as we introduce new products and
services.



     To support our sales efforts and actively promote the Akamai brand name, we
conduct comprehensive marketing programs. Our marketing strategies include an
active public relations campaign, print advertisements, online advertisements,
trade shows, strategic partnerships and on-going customer communications
programs. We focus our marketing efforts on business and trade publications,
online media outlets, industry events and sponsored activities. We participate
in a variety of Internet, computer and financial industry conferences and
encourage our officers and employees to pursue speaking engagements at these
conferences. As of September 30, 1999, we had 15 employees in our marketing
organization.


NETWORK DEPLOYMENT


     As of October 5, 1999, our network was comprised of 1,475 servers in 24
countries across 55 telecommunication networks. Some of the telecommunications
networks across which Akamai servers are deployed include: AboveNet
Communications, AT&T, Digex, Exodus Communications, GTE

                                       33
<PAGE>   36

Internetworking, interNode networks, Korea Telecom, Level 3 Communications,
OzEmail Limited, Pacific Internet, PSINet, UUNET Technologies, Verio, VisiNet
and WonderNet.

     Most of our servers are currently deployed in secure data centers served by
major domestic and international Internet service providers. These Internet
service providers provide bandwidth to deliver content from our servers to
Internet users.


     We also deploy our servers at smaller and medium-sized domestic and
international Internet service providers through our Akamai accelerated networks
program. Under this program, we offer use of our servers to Internet service
providers. In exchange, we typically do not pay for rack space to house our
servers or bandwidth to deliver content from our servers to Internet users. By
hosting Akamai servers, Internet service providers obtain access to popular
content from the Internet that is served from the Akamai network. As a result,
when this content is requested by a user, the Internet service provider does not
need to pay for the bandwidth otherwise necessary to retrieve the content from
the originating Web site.



     We are planning to expand and enhance our network by entering into
strategic relationships with network providers and integrating our technology
with networking and other network infrastructure products, such as routers and
switches, to facilitate implementation of our service by Internet service
providers.


RESEARCH AND DEVELOPMENT

     Akamai's beginnings trace to a challenge that Tim Berners-Lee, the inventor
of the World Wide Web, posed to his colleagues at MIT in early 1995 to invent a
fundamentally new and better way to deliver Internet content to users. F.
Thomson Leighton, an MIT Professor of Applied Mathematics and founder of Akamai,
recognized that a solution to Web congestion could be found in applied
mathematics and algorithms. Dr. Leighton believed that algorithms could be used
to create a network of distributed servers that could communicate as a system
and could deliver content without depending on a centralized controlling core.
Dr. Leighton, together with Daniel Lewin, one of his graduate students at MIT,
and several other researchers with expertise in computer science and data
networking, undertook the development of the mathematical algorithms necessary
to handle the dynamic routing of content.

     We believe that strong product and service development capabilities are
essential to enhancing our core technologies, developing new applications for
our technology and maintaining our competitiveness. We have invested and intend
to continue to invest a significant amount of human and financial resources in
Akamai's research and development organization.


     As of September 30, 1999, we had 64 employees devoted to our research and
development efforts. Our research and development organization is comprised of
the following groups:


     - The server group, which develops and maintains the server software used
       in our FreeFlow service;

     - The mapping group, which develops techniques for monitoring and routing
       Internet traffic;

     - The performance analysis group, which develops tools to test and monitor
       the performance of systems;

     - The graphic user interface group, which builds programs that allow our
       customers and network operations center personnel to graphically view the
       status and performance of our network in real time; and

     - The algorithm design and implementation groups, which design and
       implement the algorithms that operate our FreeFlow service and its
       derivative technologies.


     We are focusing our research and development efforts on enhancing our
FreeFlow service and building on our technology to develop new services. From
our inception in August 1998 through June 30, 1999, our engineering and
development expenses were approximately $2.3 million. We expect to continue to
commit significant resources to research and development in the future. To date,
all engineering and development expenses have been expensed as incurred.

COMPETITION

     The market for Internet content delivery services is new, rapidly evolving
and intensely competitive. We expect competition to increase both from existing
competitors and new market entrants for various components of our service. We
compete primarily on the basis of:

     - Performance of our service, including speed of delivery, reliability,
       peak crowd protection, and global content delivery capabilities;

     - Ease of implementation and use of our service;

     - Types of content delivered; and

     - Price.

     We compete primarily with companies offering products and services that
address Internet performance problems, including companies that provide Internet
content delivery services, streaming content delivery services and
equipment-based solutions to Internet performance problems, such as load
balancers and server switches.

     Our competitors may be able to respond more quickly than we can to new or
emerging technologies and changes in customer requirements. Some of our current
or potential competitors may bundle their products with other software or
hardware in a manner that may discourage Web site owners from purchasing
products we offer or Internet service providers from being willing to install
our servers.

     Increased competition could result in price reductions, fewer customer
orders, reduced gross margins and loss of market share, any of which could
materially and adversely affect our business, financial condition and
operations.

PROPRIETARY RIGHTS AND LICENSING

     Our success and ability to compete are dependent on our ability to develop
and maintain the proprietary aspects of our technology and operate without
infringing on the proprietary rights of others. We rely on a combination of
patent, trademark, trade secret and copyright laws and contractual restrictions
to protect the proprietary aspects of our technology. These legal protections
afford only limited protection for our technology. We have no patents and we
have not filed any patent applications with the United States Patent and
Trademark Office with respect to our Internet content delivery service. We seek
to limit disclosure of our intellectual property by requiring employees and
consultants with access to our proprietary information to execute
confidentiality agreements with us and by restricting access to our source code.
Due to rapid technological change, we believe that factors such as the
technological and creative skills of our personnel, new product developments and
enhancements to existing products are more important than the various legal
protections of our technology to establishing and maintaining a technology
leadership position.

     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. The laws of many countries do not protect our
proprietary rights to as great an extent as do the laws of the United States.
Litigation may be necessary in the future to enforce our intellectual property
rights, to protect our trade secrets, to determine the validity and scope of the
proprietary rights of others or to defend against claims of infringement or
invalidity. Any such resulting litigation could result in substantial costs and
diversion of resources and could have a material adverse effect on our business,
operating results and financial condition. There can be no assurance that our
means of protecting our proprietary rights will be adequate or that our
competitors will not independently develop similar technology. Any failure by us
to meaningfully protect our property could have a material adverse effect on our
business, operating results and financial condition.

     In October 1998, we entered into a license agreement with MIT under which
we were granted a royalty-free, worldwide right to use and sublicense the
intellectual property rights of MIT under various patent applications and
copyrights relating to Internet content delivery technology. We cannot predict
whether any of these applications will result in any issued patents or, if
patents are issued, any meaningful protection. Some of

                                       35
<PAGE>   38

our technology is based on technology licensed from MIT. The license has been
granted to us on an exclusive basis, but is subject to the rights of the U.S.
government to use the licensed intellectual property in government-funded
inventions. As part of the license agreement, MIT retained the right to use the
licensed intellectual property for non-commercial, teaching and educational
purposes. In connection with the license agreement, we issued 682,110 shares of
our common stock to MIT in October 1998. The license agreement is irrevocable,
but MIT may terminate the agreement if we cease our business due to insolvency
or if we materially breach the terms of the license agreement.

EMPLOYEES


     As of September 30, 1999, we had a total of 193 full-time employees and 34
part-time employees. We expect to hire additional employees through 1999.


     Our future success will depend in part on our ability to attract, retain
and motivate highly qualified technical and management personnel, for whom
competition is intense. Our employees are not represented by any collective
bargaining unit. We believe our relations with our employees are good.

President(1)
</TABLE>

- ------------
(1) Daniel M. Lewin resigned as President of Akamai and became our Chief
    Technology Officer on May 18, 1999.

     On September 2, 1998, we sold 11,391,750 shares of common stock to Mr.
Lewin for an aggregate purchase price of $63,285 pursuant to the terms of a
stock restriction agreement. The stock restriction agreement gives us the right
to repurchase a portion of these shares at the original purchase price if Mr.
Lewin ceases to provide services to us prior to August 31, 2002. However, our
right to repurchase shares held by Mr. Lewin terminates upon a change in control
of Akamai.

STOCK OPTIONS

     We did not grant any stock options to Mr. Lewin during the period from our
inception to December 31, 1998.

BENEFIT PLANS

     1998 Stock Incentive Plan.  Our 1998 stock incentive plan provides for the
grant of restricted stock and other stock-based awards and stock options. A
maximum of 28,755,600 shares of common stock are authorized to be issued
pursuant to the 1998 stock incentive plan. Our officers, employees, directors,
consultants and advisors are eligible to receive awards under the 1998 stock
incentive plan.

     The compensation committee of our board of directors administers the 1998
stock incentive plan. The compensation committee with the assistance of
management selects the recipients of awards and determines:

     - The number of shares of common stock covered by options and the dates
       upon which such options become exercisable;

     - The exercise price of options;

     - The duration of options; and

     - The number of shares of common stock subject to any restricted stock or
       other stock-based awards and the terms and conditions of such awards,
       including the conditions for repurchase, issue price and repurchase
       price.

                                       41
<PAGE>   44

     In the event of a merger or other acquisition event, our board of directors
is authorized to provide for outstanding awards to be assumed or substituted for
by the acquiror. If the acquiror does not assume or substitute for outstanding
awards, our board of directors may provide that all unexercised options will
become exercisable in full prior to the completion of such event and that these
options will terminate upon the completion of the event if not previously
exercised. In addition, immediately prior to the consummation of an acquisition
event, the vesting schedule of each outstanding option and stock-based award
will be accelerated.

     1999 Employee Stock Purchase Plan.  Our 1999 employee stock purchase plan
provides for the issuance of up to 600,000 shares of our common stock to
participating employees.

     The 1999 employee stock purchase plan, which is intended to qualify under
Section 423 of the Internal Revenue Code, contains consecutive, overlapping,
twenty-four month offering periods. Each offering period includes four six-month
purchase periods. The offering periods generally start on the first trading day
on or after June 1 and December 1 of each year. However, the first such offering
period will commence on the first trading day after the effective date of this
offering and end on the last trading day on or before November 30, 2001.

     All of our employees, including directors who are employees, and all
employees of any participating subsidiaries:


     - Whose customary employment is for more than five months in a calendar
       year; and



     - Who have been employed by us for at least seven calendar days prior to
       enrolling



are eligible to participate in the 1999 employee stock purchase plan. Employees
who would immediately after the grant own five percent or more of the total
combined voting power or value of our stock or any subsidiary are not eligible
to participate.


     To participate in the 1999 employee stock purchase plan, an employee must
authorize us to deduct from one to ten percent of his or her base pay during the
offering period. Amounts deducted and accumulated by the participant are used to
purchase shares of common stock at the end of each purchase period. The price of
stock purchased under the 1999 employee stock purchase plan is 85% of the lower
of the fair market value of the common stock (i) at the beginning of the
offering period, or (ii) at the end of the purchase period; provided, however,
that under certain circumstances, the purchase price may be adjusted to a price
not less than 85% of the lower of the fair market value on the common stock on
(i) the date our stockholders approve an increase in shares reserved for
issuance under the 1999 employee stock purchase plan or (ii) at the end of the
purchase period. In the event the fair market value at the end of a purchase
period is less than the fair market value at the beginning of the offering
period, the participants will be withdrawn from the current offering period

                          DESCRIPTION OF CAPITAL STOCK


     After this offering, the authorized capital stock of Akamai will consist of
300,000,000 shares of common stock, $0.01 par value per share, and 5,000,000
shares of preferred stock, $0.01 par value per share. As of September 30, 1999,
there were outstanding:


     - 44,832,810 shares of common stock held by 101 stockholders of record; and


     - options and warrants to purchase an aggregate of 14,396,061 shares of
       common stock.



     Upon completion of this offering and the conversion of all outstanding
shares of preferred stock into common stock, there will be 90,408,428 shares of
common stock outstanding.


COMMON STOCK

     Holders of our common stock are entitled to one vote for each share held on
matters submitted to a vote of stockholders. Holders of our common stock do not
have cumulative voting rights. Accordingly, holders of a majority of the shares
of common stock entitled to vote in any election of directors may elect all of
the directors standing for election. Holders of common stock are entitled to
receive their proportionate share of any dividends declared by the Board of
Directors, subject to any preferential dividend rights of outstanding preferred
stock. Upon the liquidation, dissolution or winding up of Akamai, the holders of
common stock are entitled to receive ratably the net assets of Akamai available
after the payment of all debts and other liabilities and subject to the
preferential rights of any outstanding preferred stock. The common stock has no
preemptive, subscription, redemption or conversion rights. All outstanding
shares of common stock are fully paid and nonassessable. The rights, preferences
and privileges of the common stock are subject to the rights of the holders of
shares of any series of preferred stock which Akamai may designate and issue in
the future.

PREFERRED STOCK

     Our Board of Directors will be authorized to issue shares of preferred
stock in one or more series without stockholder approval. The Board will have
discretion to determine the rights, preferences, privileges and restrictions,
including voting rights, dividend rights, conversion rights, redemption
privileges and liquidation preferences of each series of preferred stock.

     The purpose of authorizing the Board of Directors to issue preferred stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances. The Board's ability to issue preferred
stock will provide desirable flexibility in connection with possible
acquisitions and other corporate purposes and could make it more difficult for a
third party to acquire, or could discourage a third party from acquiring, a
majority of our outstanding voting stock. The issuance of preferred stock with
voting and conversion rights may adversely affect the voting power of the
holders of common stock. We have no present plans to issue any shares of
preferred stock.

DELAWARE LAW AND OUR CHARTER AND BY-LAW PROVISIONS; ANTI-TAKEOVER EFFECTS

     Akamai is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for three years after the date of the transaction in which the
person became an interested stockholder, unless the business combination is
approved in a prescribed manner. A "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
interested stockholder. An "interested stockholder" is a person who, together
with affiliates and associates, owns, or within three years did own, 15% or more
of the corporation's voting stock.

     Akamai's certificate of incorporation and by-laws to be effective on the
closing of this offering provide:

     - That the Board of Directors be divided into three classes, as nearly
       equal in size as possible, with no class having more than one director
       more than any other class, with staggered three-year terms;

     - That directors may be removed only for cause by the vote of the holders
       of at least 66% of the shares of our capital stock entitled to vote; and

                                       48
<PAGE>   51

     - That any vacancy on the Board of Directors, however occurring, including
       a vacancy resulting from an enlargement of the Board, may only be filled
       by vote of a majority of the directors then in office.

     The classification of the Board of Directors and the limitations on the
removal of directors and filling of vacancies could make it more difficult for a
third party to acquire, or discourage a third party from acquiring, Akamai.

     The certificate of incorporation and by-laws to be effective on the closing
of this offering also provide that, after the closing of this offering:

     - Any action required or permitted to be taken by the stockholders at an
       annual meeting or special meeting of stockholders may only be taken if it
       is properly brought before such meeting and may not be taken by written
       action in lieu of a meeting; and

     - Special meetings of the stockholders may only be called by the Chairman
       of the Board of Directors, the President, or by the Board of Directors.
       Our by-laws will also provide that, in order for any matter to be
       considered "properly brought" before a meeting, a stockholder must comply
       with requirements regarding advance notice to us.

     These provisions could delay until the next stockholders' meeting
stockholder actions which are favored by the holders of a majority of our
outstanding voting securities. These provisions may also discourage another
person or entity from making a tender offer for our common stock, because such
person or entity, even if it acquired a majority of our outstanding voting
securities, would be able to take action as a stockholder only at a duly called
stockholders meeting, and not by written consent.

     Delaware law provides that the vote of a majority of the shares entitled to
vote on any matter is required to amend a corporation's certificate of
incorporation or by-laws, unless a corporation's certificate of incorporation or
by-laws, as the case may be, requires a greater percentage. Our certificate of
incorporation requires the vote of the holders of at least 75% of the shares of
our capital stock entitled to vote to amend or repeal any of the foregoing
provisions of our certificate of incorporation. Generally, our by-laws may be
amended or repealed by a majority vote of the Board of Directors or the holders
of a majority of the shares of our capital stock issued and outstanding and
entitled to vote. Changes to our by-laws regarding special meetings of
stockholders, written actions of stockholders in lieu of a meeting, and the
election, removal and classification of members of the Board of Directors
require the vote of the holders of at least 75% of the shares of our capital
stock entitled to vote. The stockholder vote would be in addition to any
separate class vote that might in the future be required pursuant to the terms
of any series preferred stock that might be then outstanding.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     Our certificate of incorporation provides that our directors and officers
shall be indemnified by us except to the extent prohibited by Delaware law. This
indemnification covers all expenses and liabilities reasonably incurred in
connection with their services for or on behalf of us. In addition, our
certificate of incorporation provides that our directors will not be personally
liable for monetary damages to us or to our stockholders for breaches of their
fiduciary duty as directors, unless they violated their duty of loyalty to us or
our stockholders, acted in bad faith, knowingly or intentionally violated the
law, authorized illegal dividends or redemptions or derived an improper personal
benefit from their action as directors.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is BankBoston, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE


     Upon completion of this offering, we will have 90,408,428 shares of common
stock outstanding, assuming no exercise of outstanding options. Of these shares,
the shares to be sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, except that any
shares purchased by our affiliates, as that term is defined in Rule 144 under
the Securities Act, may generally only be sold in compliance with the
limitations of Rule 144 described below. The remaining 82,408,428 shares of
common stock are "restricted securities" under Rule 144. Generally, restricted
securities that have been owned for at least two years may be sold immediately
after the completion of this offering and restricted securities that have been
owned for at least one year may be sold 90 days after the completion of this
offering.


SALES OF RESTRICTED SHARES

     In general, under Rule 144, stockholders, including our affiliates, who
have beneficially owned shares for at least one year are entitled to sell,
within any three-month period, a number of these shares that does not exceed the
greater of one percent of the then outstanding shares of common stock and the
average weekly trading volume in the common stock in the over-the-counter market
during the four calendar weeks preceding the date on which notice of such sale
is filed, provided requirements concerning availability of public information,
manner of sale and notice of sale are satisfied. In addition, our affiliates
must comply with the restrictions and requirements of Rule 144, other than the
one-year holding period requirement, in order to sell shares of common stock
which are not restricted securities.

     Under Rule 144(k), a stockholder who is not an affiliate and has not been
an affiliate for at least three months prior to the sale and who has
beneficially owned shares for at least two years may sell these shares without
compliance with the foregoing requirements. In meeting the holding periods
described above, a stockholder can include the holding periods of a prior owner
who was not an affiliate. The holding periods described above do not begin until
the stockholder pays the full purchase price or other consideration. Rule 701
provides that currently outstanding shares of common stock acquired under our
employee compensation plans may be sold beginning 90 days after the date of this
prospectus by stockholder other than affiliates subject only to the manner of
sale provisions of Rule 144 and by affiliates under Rule 144 without compliance
with its one-year holding period requirement.

entered into lock-up agreements with the underwriters. Without the prior written

(2) enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of the common stock,

could be expected, to result in, the disposition by any person, directly or

common stock and the holders of warrants to purchase approximately 2,077,072
shares of common stock will be entitled to rights with respect to the

</TABLE>


     The underwriters are offering the shares subject to their acceptance of the
shares from us and subject to prior sale. The underwriting agreement provides
that the obligations of the several underwriters to pay for and accept delivery
of the shares of common stock offered in this offering are subject to customary
closing conditions. The underwriters are obligated to take and pay for all of
the shares of common stock offered in this offering, other than those covered by
the over-allotment option described below, if any such shares are taken.

     The underwriters initially propose to offer part of the shares of common
stock directly to the public at the initial public offering price set forth on
the cover page of this prospectus and part to dealers at a price that represents
a concession not in excess of $          per share under the initial public
offering price. Any underwriters may allow, and the dealers may reallow, a
concession not in excess of $          per share to other underwriters or to
other dealers. After the initial offering of the shares of common stock, the
offering price and other selling terms may from time to time be varied by the
representatives of the underwriters.


     We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to an aggregate of 1,200,000
additional shares of common stock at the initial public offering price set forth
on the cover page hereof, less underwriting discounts and commissions. The
underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, made in connection with this offering of common stock.
To the extent this over-allotment option is exercised, each underwriter will
become obligated, subject to other conditions, to purchase approximately the
same percentage of additional shares of common stock as the number set forth
next to such underwriter's name in the preceding table bears to the total number
of shares of common stock set forth next to the names of all underwriters in the
preceding table.


     The underwriters have informed us that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
common stock offered by them.


     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 300,000 shares of common stock offered in this
offering to directors, officers, employees, business associates and related
persons of Akamai. In addition, at our request, the underwriters have reserved
for sale, at the initial public offering price, up to 1,900,000 shares of common
stock offered in this offering to Internet-related companies, including
strategic network, technology and content providers, with whom we have or may
seek to establish a business relationship. The underwriters have also reserved
for sale, at the initial public offering price, up to 400,000 shares of common
stock offered in this offering for Baker Communications Fund, L.P., one of our
stockholders. The number of shares of common stock available for sale to the
general public will be reduced to the extent such individuals or entities
purchase such reserved shares. Any reserved shares which are not so purchased
will be offered by the underwriters to the general public on the same basis as
the other shares of common stock offered by the Prospectus for this offering.


     We have filed an application for our common stock to be quoted on the
Nasdaq National Market under the symbol "AKAM."

     Akamai, our directors and executive officers and substantially all other
stockholders are expected to agree that, without the prior written consent of
Morgan Stanley & Co. Incorporated on behalf of the underwriters, during the
period ending 180 days after the date of this prospectus, he, she or it will
not, directly or indirectly:

     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase, lend or otherwise transfer or dispose of,
       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

     - Enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of common
       stock,

whether any such transaction described above is to be settled by delivery of
common stock or such other securities, in cash or otherwise.

     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
common stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
common stock in the offering if the syndicate repurchases previously distributed
shares of common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the common stock above independent market
levels. The underwriters are not required to engage in these activities and may
end any of these activities at any time.

     We and the underwriters have agreed to indemnify each other against
liabilities in connection with this offering, including liabilities under the
Securities Act.

     Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners has been named as a lead or co-manager on 56 filed
public offerings of equity securities, of which 31 have been completed, and has
acted as a syndicate member in an additional 27 public offerings of equity
securities. Thomas Weisel Partners does not have any material relationship with
us or any of our officers, directors or other controlling persons, except with
respect to its contractual relationship with us pursuant to the underwriting
agreement entered into in connection with this offering.

PRICING OF THE OFFERING

     Prior to this offering, there has been no public market for the shares of
common stock. Consequently, the public offering price for the shares of common
stock will be determined by negotiations between Akamai and the representatives
of the underwriters. Among the factors to be considered in determining the
public offering price will be:

     - Our record of operations, our current financial position and future
       prospects;

     - The experience of our management;

     - Sales, earnings and other financial and operating information in recent
       periods; and

     - The price-earnings ratios, price-sales ratios, market prices of
       securities and financial and operating information of companies engaged
       in activities similar to ours.

     The estimated public offering price range set forth on the cover page of
this preliminary prospectus is subject to change as a result of market
conditions and other factors.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Akamai Technologies, Inc.:

     In our opinion, the accompanying balance sheets and the related statements
of operations, cash flows and convertible preferred stock and stockholders'
deficit present fairly in all material respects, the financial position of
Akamai Technologies, Inc. as of December 31, 1998 and June 30, 1999, and the
results of its operations and its cash flows for the period from inception
(August 20, 1998) to December 31, 1998 and for the six-month period ended June
30, 1999, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                         NOTES TO FINANCIAL STATEMENTS

1.  NATURE OF BUSINESS:

     Akamai Technologies, Inc. ("Akamai" or the "Company") provides a global
delivery service for Internet content that improves Web site speed and
reliability and protects against Web site crashes due to demand overloads. The
Company's FreeFlow service, which is marketed to large businesses and to other
businesses with an internet focus, delivers customers' web content through a
worldwide server network by locating the content geographically closer to their
users.

     The Company has experienced substantial net losses since its inception and,
as of June 30, 1999, had an accumulated deficit of $10,805,037. Such losses and
accumulated deficit resulted from the Company's lack of substantial revenue and
costs incurred in the development of the Company's service and in the
establishment of the Company's network. For the foreseeable future, the Company
expects to continue to experience significant growth in its operating expenses
in order to execute its current business plan, particularly engineering and
development and sales, general and administrative expenses.

     The Company has a single operating segment, Internet content delivery
service. The Company has no organizational structure dictated by product lines,
geography or customer type. All revenue earned to date have been generated from
U.S. based customers.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CASH AND CASH EQUIVALENTS

     Cash equivalents consist of cash held in bank deposit accounts and
short-term investments with remaining maturities of three months or less at the
date of purchase.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, net of accumulated depreciation.
Depreciation is computed on a straight-line basis over estimated useful lives of
three to five years. Leasehold improvements are depreciated over the shorter of
related lease terms or the estimated useful lives. Property and equipment
acquired under capital lease is depreciated over the shorter of related lease
terms or the useful life of the asset. Upon retirement or sale, the costs of the
assets disposed and the related accumulated depreciation are removed from the
accounts and any resulting gain or loss is included in the determination of
income. Repairs and maintenance costs are expensed as incurred.

  INTANGIBLE ASSETS

     Intangible assets consist primarily of the cost of acquired license rights
to content delivery technology. Intangible assets are amortized using the
straight-line method over ten years, based on the estimated useful life. The
carrying value of the intangible assets is reviewed on a quarterly basis for the
existence of facts or circumstances both internally and externally that may
suggest impairment. To date, no such impairment has occurred. The Company
determines whether an impairment has occurred based on gross expected future
cash flows and measures the amount of the impairment based on the related future
estimated discounted cash flows. The cash flow estimates used to determine the
impairment, if any, contain management's best estimates, using appropriate and
customary assumptions and projections at that time.

  REVENUE RECOGNITION

     The Company derives revenue from the sale of its FreeFlow service under
contracts with terms typically ranging from three to 12 months. The Company
recognizes revenue based on fees for the amount of Internet content delivered
through the Company's service. These contracts also provide for minimum monthly
fees. Revenue may also be derived from one-time implementation fees which are
recognized ratably over the period of the related contracts.

                           AKAMAI TECHNOLOGIES, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  COSTS OF SERVICE


     Cost of service consists of depreciation of network equipment used in
providing the Company's FreeFlow service, fees paid to network providers for
bandwidth and monthly fees for housing the Company's servers in third-party
network data centers. The Company enters into contracts for bandwidth with
third-party network providers with terms typically ranging from six months to
three years. These contracts commit the Company to minimum monthly fees plus
additional fees for bandwidth usage above the contracted level. Under the Akamai
accelerated networks program, the Company provides Akamai servers without charge
to smaller Internet service providers which, in turn, provide the Company with
rack space for the Company's servers and bandwidth to deliver content. The
Company does not recognize as revenue any value to the Internet service
providers associated with the use of the Company's servers and does not expense
the value of the rack space and bandwidth received.


  STOCK-BASED COMPENSATION

     The Company accounts for stock-based awards to employees using the
intrinsic value method as prescribed by Accounting Principles Board Opinion
("APB") No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, no compensation expense is recorded for options
issued to employees in fixed amounts and with fixed exercise prices at least
equal to the fair market value of the Company's common stock at the date of
grant. The Company has adopted the provisions of Statement of Financial
Accounting Standard ("SFAS") No. 123, "Accounting for Stock-Based Compensation,"
through disclosure only (Note 9). All stock-based awards to nonemployees are
accounted for at their fair value in accordance with SFAS No. 123.

  ENGINEERING AND DEVELOPMENT COSTS

     Engineering and development costs consist primarily of salaries and related
personnel costs for the design, deployment, testing and enhancement of the
Company's service and the Company's network.

     Costs incurred in the engineering and development of the Company's service
are expensed as incurred, except for certain software development costs. Costs
associated with the development of computer software are expensed prior to the
establishment of technological feasibility (as defined by SFAS No. 86,
"Accounting for the costs of Computer Software to be Sold, Leased, or Otherwise
Marketed") and capitalized thereafter. The Company also has adopted Statement of
Position ("SOP") 98-1, which requires computer software costs associated with
internal use software to be charged to operations as incurred until certain
capitalization criteria are met. Costs eligible for capitalization under SFAS
No. 86 and SOP 98-1 have been insignificant to date.

  USE OF ESTIMATES

     The presentation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenue and expenses during the reporting
period. Actual results could differ from those estimates. Significant estimates
in these financial statements include valuation of deferred tax assets and
useful lives of depreciable assets.

  CONCENTRATIONS OF CREDIT RISK

     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of cash, cash equivalents and
accounts receivable. At December 31, 1998 and June 30, 1999, the Company had
cash balances at certain financial institutions in excess of federally insured
limits. However, the Company does not believe that it is subject to unusual
credit risk beyond the normal credit risk associated with

                                       F-8

                           AKAMAI TECHNOLOGIES, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

commercial banking relationships. As of June 30, 1999, two customers accounted
for 77% and 15% of accounts receivable. These customers also accounted for 75%
and 14% of total revenue for the six-month period ended June 30, 1999.

  INCOME TAXES

     Deferred taxes are determined based on the difference between the financial
statement and tax basis of assets and liabilities using enacted tax rates in
effect in the years in which the differences are expected to reverse. Valuation
allowances are provided if, based upon the weight of available evidence, it is
more likely than not some or all of the deferred tax assets will not be
realized.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of the Company's financial instruments, which include
cash equivalents, accounts receivable, notes receivable, accounts payable,
accrued expenses and notes payable approximate their fair values at June 30,
1999.

  OTHER COMPREHENSIVE INCOME

     The Company has adopted SFAS No. 130, "Reporting Comprehensive Income,"
which established standards for reporting and displaying comprehensive income
and its components in a financial statement that is displayed with the same
prominence as other financial statements. Comprehensive loss is equal to net
loss, for the period from inception (August 20, 1998) to December 31, 1998 and
for the six-month period ended June 30, 1999.

  RECENT ACCOUNTING PRONOUNCEMENT

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
Company, to date, has not engaged in derivative and hedging activities, and
accordingly does not believe that the adoption of SFAS No. 133 will have a
material impact on the financial reporting and related disclosures of the
Company. The Company will adopt SFAS No. 133 as required by SFAS No. 137,
"Deferral of the Effective Date of the FASB Statement No. 133," in fiscal year
2001.

  PRO FORMA BALANCE SHEET (UNAUDITED)

     Upon the closing of the Company's initial public offering, all of the
outstanding shares of convertible preferred stock as of June 30, 1999 will
automatically convert into approximately 32,215,694 shares of common stock. The
unaudited pro forma presentation of the balance sheet has been prepared assuming
the conversion of all shares of convertible preferred stock into common stock at
June 30, 1999. All references to pro forma information in the notes to the
financial statements are unaudited.

3.  NET LOSS PER SHARE AND PRO FORMA NET LOSS PER SHARE:

     Basic net loss per share is computed using the weighted average number of
common shares outstanding during the period. Dilutive net loss per share is
computed using the weighted average number of common shares outstanding during
the period, plus the dilutive effect of common stock equivalents. Common stock
equivalent shares consist of convertible preferred stock, unvested restricted
common stock, stock options and warrants. During the period from inception
(August 20, 1998) to December 31, 1998 and the six-month period ended June 30,
1999, options to purchase 1,287,000 and 9,116,000 shares of common stock,

respectively, unvested restricted common stock of 18,049,104 and 19,950,804,
respectively, preferred stock convertible into 19,800,000 and 32,215,694 shares
of common stock, respectively, and warrants to purchase none and 2,075,100
shares of common stock, respectively, were excluded from the calculation of
earnings per share since their inclusion would be antidilutive. Pro forma basic
and diluted net loss per share have been calculated assuming the conversion of
all outstanding shares of preferred stock into common stock, as if the shares
had converted immediately upon their issuance. Accordingly, net loss has not
been adjusted for the accrued dividends for preferred stock in the calculation
of pro forma loss per share.

     The following is a calculation of pro forma net loss per share (unaudited):

5.  SENIOR SUBORDINATED NOTES:

     During April 1999, Akamai entered into note and warrant purchase agreements
with private investors. Under the agreements, Akamai issued 15% subordinated
demand notes payable in the aggregate amount of $15,000,000 due in May 2004. In
connection with the notes, the Company also issued warrants to purchase an
aggregate of 2,002,836 shares of common stock at $2.50 per share in exchange for
cash. These warrants expire in May 2004. The fair value of the warrants at the
time of issuance was estimated to be approximately $3,876,477, which was
recorded as additional paid-in capital and reduced the carrying value of the
notes. The fair value was estimated using the Black-Scholes model with the
following assumptions: dividend yield of 0%, volatility of 100%, risk free
interest rate of 5.1% and an expected life of five years. The discount on the
notes is being amortized over the term of the notes. For the six months ended
June 30, 1999, interest expense of $129,215 related to the fair value of the
warrants was recognized.

determined by the Board of Directors but in no case may the exercise price be
less than the statutory minimum. Vesting of options granted is at the discretion
of the Board of Directors, which typically is four years.

     SFAS No. 123, "Accounting for Stock-Based Compensation," encourages but
does not require companies to record compensation cost for stock-based employee
compensation at fair value. The Company has chosen to account for stock-based
compensation granted to employees using the intrinsic value method prescribed in
APB No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, deferred compensation cost for restricted stock
awards and stock options granted to employees is measured as the excess, if any,
of the fair value of the Company's stock at the date of the grant over the
amount that must be paid to acquire the stock. From inception (August 20, 1998)
through December 31, 1998 and the six-month period ended June 30, 1999, the
Company recorded approximately $1,711,600 and $7,835,000, respectively, in
deferred compensation for restricted stock awards and options to purchase common
stock granted at exercise prices subsequently determined to be below the fair
value of the common stock. Compensation expense of $205,617 and $1,338,608 was
recognized during the period from inception (August 20, 1998) through December
31, 1998 and the six-month period ended June 30, 1999, respectively.

     Had the value of options granted been measured using the fair value method
prescribed by SFAS No. 123, the fair value of the options granted from inception
(August 20, 1998) through December 31, 1998 and the six-month period ended June
30, 1999 is estimated to be $0.01 and $1.59 per share, respectively. The fair
value of the option grant was estimated on the date of grant using the
Black-Scholes option pricing model with the following assumptions: risk free
rate of 5.5%; no expected dividends; an expected life of 10 years; and no
volatility. Had the Company accounted for stock options to employees under the
fair value method prescribed under SFAS No. 123, net losses as reported for the
period from inception (August 20, 1998) to December 31, 1998 and the six-month
period ended June 30, 1999 would have been $890,890 and $9,818,746,
respectively, under SFAS No. 123. Basic and diluted net loss per share would
have been $(0.06) and $(0.52) on a pro forma basis for the period from inception
(August 20, 1998) to December 31, 1998 and the six-month period ended June 30,
1999, respectively. The effects of applying SFAS No. 123 in this pro forma
disclosure are not indicative of future amounts.

</TABLE>

     As of June 30, 1999, the Company has federal and state net operating loss
carryforwards of $7,033,000 which begin to expire in 2019. These net operating
loss carryforwards may be used to offset future federal and state taxable income
tax liabilities. The Company also has federal and state tax credit carryforwards
of $58,000 and $36,000, respectively.

     Ownership changes resulting from the Company's issuance of capital stock
may limit the amount of net operating loss and tax credit carryforwards that can
be utilized annually to offset future taxable income. The amount of the annual
limitation is determined based upon the Company's value immediately prior to the
ownership change. Subsequent significant changes in ownership could further
affect the limitation in future years.

11.  EMPLOYEE BENEFIT PLAN:

     In January 1999, the Company established a savings plan for its employees
which is designed to be qualified under Section 401(k) of the Internal Revenue
Code. Eligible employees are permitted to contribute to the 401(k) plan through
payroll deductions within statutory and plan limits. The Company has not
contributed to the savings plan to date.

Dividends will be paid only in the event of a liquidation or redemption. The
Series E preferred stock is convertible at any time by the holders, at the then
applicable conversion rate (currently 2-to-1) adjusted for certain events such
as stock splits and dividends. The Series E preferred stock is redeemable,
subject to the approval of the holders of 66% of the then outstanding shares of
Series E preferred stock.

     In connection with the issuance of Series E preferred stock, the authorized
common stock increased from 60,000,000 to 300,000,000 and the authorized
preferred stock increased from 5,000,000 to 10,000,000 shares. All amounts have
been restated to reflect the increase in authorized shares.

     The Company will bear all expenses shown above.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article SEVENTH of the Registrant's Amended and Restated Certificate of
Incorporation (the "Restated Certificate") provides that no director of the
Registrant shall be personally liable for any monetary damages for any breach of
fiduciary duty as a director, except to the extent that the Delaware General
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.

     Article EIGHTH of the Restated Certificate provides that a director or
officer of the Registrant (a) shall be indemnified by the Registrant against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement incurred in connection with any litigation or other legal proceeding
(other than an action by or in the right of the Registrant) brought against him
by virtue of his position as a director or officer of the Registrant if he acted
in good faith and in a manner he reasonably believed to be in, or not opposed
to, the best interests of the Registrant, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful and (b) shall be indemnified by the Registrant against all expenses
(including attorneys' fees) and amounts paid in settlement incurred in
connection with any action by or in the right of the Registrant brought against
him by virtue of his position as a director or officer of the Registrant if he
acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the Registrant, except that no indemnification
shall be made with respect to any matter as to which such person shall have been
adjudged to be liable to the Registrant, unless the Court of Chancery of
Delaware determines that, despite such adjudication but in view of all of the
circumstances, he is entitled to indemnification of such expenses.
Notwithstanding the foregoing, to the extent that a director or officer has been
successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he is required to be indemnified by
the Registrant against all expenses (including attorneys' fees) incurred in
connection therewith. Expenses shall be advanced to a director or officer at his
request, unless it is determined that he did not act in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Registrant, and, with respect to any criminal action or proceeding had
reasonable cause to believe that his conduct was unlawful, provided that he
undertakes to repay the amount advanced if it is ultimately determined that he
is not entitled to indemnification for such expenses.

     Indemnification is required to be made unless the Registrant determines
that the applicable standard of conduct required for indemnification has not
been met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the

                                      II-1
<PAGE>   79

Registrant fails to make an indemnification payment within 60 days after such
payment is claimed by such person, such person is permitted to petition the
court to make an independent determination as to whether such person is entitled
to indemnification. As a condition precedent to the right of indemnification,
the director or officer must give the Registrant notice of the action for which
indemnity is sought and the Registrant has the right to participate in such
action or assume the defense thereof.

     Article EIGHTH of the Restated Certificate further provides that the
indemnification provided therein is not exclusive, and provides that in the
event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers the Registrant must indemnify
those persons to the fullest extent permitted by such law as so amended.

     Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, in any criminal proceeding, if such person
had no reasonable cause to believe his conduct was unlawful; provided that, in
the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the adjudicating court determines that such indemnification is
proper under the circumstances.

     The Underwriting Agreement provides that the Underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of the Company against certain liabilities, including liabilities under
the Securities Act of 1933, as amended (the "Act"). Reference is made to the
form of Underwriting Agreement to be filed as Exhibit 1.1 hereto.

     The Registrant has obtained liability insurance for its officers and
directors.

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Act"), may be permitted to directors, officers and
controlling persons of the registrant pursuant to the Delaware General
Corporation Law, the Restated Certificate of the registrant, the Underwriting
Agreement, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act, and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, the registrant
will, unless in the opinion of counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

     The undersigned registrant hereby undertakes that:

          (1) For purpose of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4), or
     497(h) under the Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.

          (2) For purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of prospectus shall be deemed

     Re: REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:


     This opinion is furnished to you in connection with a Registration
Statement on Form S-1 (File No. 333-85679) (as amended, the "Registration
Statement") filed with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Securities
Act"), for the registration of 9,200,000 shares of Common Stock, $.01 par value
per share (the "Shares"), of Akamai Technologies, Inc., a Delaware corporation
(the "Company"), including 1,200,000 Shares issuable upon exercise of an
over-allotment option granted by the Company.


     The Shares are to be sold by the Company pursuant to an underwriting
agreement (the "Underwriting Agreement") to be entered into by and among the
Company and Morgan Stanley Dean Witter, Donaldson, Lufkin & Jenrette, Salomon
Smith Barney and Thomas Weisel Partners LLC, as representatives of the several
underwriters named in the Underwriting Agreement, the form of which has been
filed as Exhibit 1.1 to the Registration Statement.

     We are acting as counsel for the Company in connection with the issue and
sale by the Company of the Shares. We have examined signed copies of the
Registration Statement as filed with the Commission. We have also examined and
relied upon the Underwriting Agreement, minutes of meetings of the stockholders
and the Board of Directors of the Company as provided to us by the Company,
stock record books of the Company as provided to us by the Company, the
Certificate of Incorporation and By-Laws of the Company, each as restated
and/or amended to date, and such other documents as we have deemed necessary
for purposes of rendering the opinions hereinafter set forth.

2

     In our examination of the foregoing documents, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents
submitted to us as copies, the authenticity of the originals of such latter
documents and the legal competence of all signatories of such documents.

     We assume that the appropriate action will be taken, prior to the offer
and sale of the Shares in accordance with the Underwriting Agreement, to
register and qualify the Shares for sale under all applicable state securities
or "blue sky" laws.

     We express no opinion herein as to the laws of any state or jurisdiction
other than the state laws of The Commonwealth of Massachusetts, the Delaware
General Corporation Law statute and the federal laws of the United States of
America.


<PAGE>   2

     Based upon and subject to the foregoing, we are of the opinion that the
Shares have been duly authorized for issuance and, when the Shares are issued
and paid for in accordance with the terms and conditions of the Underwriting
Agreement, the Shares will be validly issued, fully paid and nonassessable.

     It is understood that this opinion is to be used only in connection with
the offer and sale of the Shares while the Registration Statement is in effect.

     Please note that we are opining only as to the matters expressly set forth
herein, and no opinion should be inferred as to any other matters. This
opinion is based upon currently existing statutes, rules, regulations and
judicial decisions, and we disclaim any obligation to advise you of any change
in any of these sources of law or subsequent legal or factual developments
which might affect any matters or opinions set forth herein.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act and to the use of our
name therein and in the related Prospectus under the caption "Legal Matters."
In giving such consent, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission.

                                   Very truly yours,


                                   HALE AND DORR LLP

                            AKAMAI TECHNOLOGIES, INC.

                        1999 EMPLOYEE STOCK PURCHASE PLAN

         The following constitute the provisions of the 1999 Employee Stock
Purchase Plan of Akamai Technologies, Inc.

         1. PURPOSE. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

         2. DEFINITIONS.

                  a. "BOARD" shall mean the Board of Directors of the Company.

                  b. "CODE" shall mean the Internal Revenue Code of 1986, as
amended.

                  c. "COMMON STOCK" shall mean the Common Stock of the Company.

                  d. "COMPANY" shall mean Akamai Technologies, Inc. and any
Designated Subsidiary of the Company.

                  e. "COMPENSATION" means the amount of money reportable on
your Federal Income Tax Withholding Statement (Form W-2) before any
withholdings for health insurance or under a Section 401(k), 125, 129 or
similar plan, excluding third party sick or disability pay, allowances and
reimbursements for expenses such as relocation allowances or travel expenses,
whether specifically designated as such or designated as signing bonuses,
income or gains attributable to restricted stock, stock options, stock
appreciation rights or other similar equity based compensation, imputed income
for non cash items, such as life insurance premiums, and similar items, whether
or not specifically itemized on the Form W-2.

                  f. "DESIGNATED SUBSIDIARY" shall mean any Subsidiary which has
been designated by the Board from time to time in its sole discretion as
eligible to participate in the Plan.

                  g. "EMPLOYEE" shall mean any individual who is an Employee of
the Company for tax purposes whose customary employment with the Company is more
than five (5) months in any calendar year. For purposes of the Plan, the
employment relationship shall be treated as continuing intact while the
individual is on sick leave or other leave of absence approved by the Company.

Dollars ($25,000) worth of stock (determined at the fair market value of the

         5. PARTICIPATION.

                  a. An eligible Employee may become a participant in the Plan
by completing a subscription agreement in the form of EXHIBIT A authorizing
payroll deductions in a form provided by the Company's payroll office and filing
it with the Company's payroll office prior to the applicable Enrollment Date.

                  b. Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such authorization is applicable, unless sooner
termination by the participant as provided in Section 10 hereof.

         6. PAYROLL DEDUCTIONS.

                  a. At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period.

                  b. All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

                  c. A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions to not more than 10 percent (10%) or less than
zero percent (0%) not more than four (4) times during each Offering Period by
completing or filing with the Company a new subscription agreement authorizing
such change in payroll deduction


                                       4
<PAGE>   5


rate. The Board may, in its discretion, increase or decrease the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

                  d. At the time the option is exercised, in whole or in part,
or at the time some or all of the Company's Common Stock issued under the Plan
is disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

         7. GRANT OF OPTION. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase (at the applicable Purchase Price) up to a whole number of
shares of the Company's Common Stock determined by dividing $50,000 by the fair
market value of a share of Common Stock on the Enrollment Date (subject to any
adjustment pursuant to section 19), and provided that such purchase shall be
subject to the limitations set forth in Section 3(b) and 13 hereof. The option
shall be exercisable as to 25% of the total number of shares on each exercise
date during the Offering Period. Exercise of the option shall occur as provided
in Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof. The option shall expire on the last day of the Offering Period.

         8. EXERCISE OF OPTION. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

         9. DELIVERY. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant,


                                       5
<PAGE>   6


as appropriate, of a certificate representing the shares purchased upon exercise
of his or her option.

         10. WITHDRAWAL.

                  a. A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of EXHIBIT B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

                  b. A participant's withdrawal from an Offering Period shall
not have any effect upon his or her eligibility to participate in any similar
plan which may hereafter be adopted by the Company or in succeeding Offering
Periods which commence after the termination of the Offering Period from which
the participant withdraws.

         11. TERMINATION OF EMPLOYMENT. Upon a participant's ceasing to be an
Employee, for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of employment during the
period in which the participant is subject to such payment in lieu of notice.

         12. INTEREST. No interest shall accrue on the payroll deductions of a
participant in the Plan.

         13. STOCK.

                  a. Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 600,000 shares. If, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.


                                       6
<PAGE>   7


                  b. The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

                  c. Shares to be delivered to a participant under the Plan
shall be registered in the name of the participant or in the name of the
participant and his or her spouse.

         14. ADMINISTRATION. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

         15. DESIGNATION OF BENEFICIARY.

                  a. A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a participant
may file a written designation of a beneficiary who is to receive any cash from
the participant's account under the Plan in the event of such participant's
death prior to exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                  b. Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

         16. TRANSFERABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.


                                       7
<PAGE>   8


         17. USE OF FUNDS. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

         18. REPORTS. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

         19. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,
LIQUIDATION, MERGER OR ASSET SALE.

                  a. CHANGES IN CAPITALIZATION. Subject to any required action
by the stockholders of the Company, the Reserves, the maximum number of shares
each participant may purchase each Purchase Period (pursuant to Section 7), as
well as the price per share and the number of shares of Common Stock covered by
each option under the Plan which has not yet been exercised shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of
any convertible securities of the Company shall not be deemed to have been
"effected without receipt of consideration." Such adjustment shall be made by
the Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an option.

                  b. DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "NEW EXERCISE DATE"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

                  c. MERGER OR ASSET SALE. In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, each outstanding option shall be
assumed or an equivalent option substituted by the successor corporation or a
Parent or Subsidiary of the


                                       8
<PAGE>   9


successor corporation. In the event that the successor corporation refuses to
assume or substitute for the option, any Purchase Periods then in progress shall
be shortened by setting a New Exercise Date (the "NEW EXERCISE DATE") and any
Offering Periods then in progress shall end on the New Exercise Date. The New
Exercise Date shall be before the date of the Company's proposed sale or merger.
The Board shall notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

         20. AMENDMENT OR TERMINATION.

                  a. The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 19
hereof, no such termination can affect options previously granted, provided that
an Offering Period may be terminated by the Board of Directors on any Exercise
Date if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders. Except as provided in Section 19
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any
other applicable law, regulation or stock exchange rule), the Company shall
obtain stockholder approval in such a manner and to such a degree as required.

                  b. Without stockholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

         21. NOTICES. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

         22. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

                  As a condition to the exercise of an option, the Company may
require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

         23. TERM OF PLAN. The Plan shall become effective upon the date of the
Company's initial public offering of its equity securities registered on Form
S-1 with the Securities and Exchange Commission. It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 20 hereof.

         24. AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD. To the extent
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

_______  Original Application                     Enrollment Date:  ____________
_______  Change in Payroll Deduction Rate (Complete only Section 2 and date and
sign).
_______  Change of Beneficiary (ies) (Complete only Section 8 and date and
sign).


         1. ______________________________ hereby elects to participate in the
Akamai Technologies, Inc. 1999 Employee Stock Purchase Plan (the "EMPLOYEE STOCK
PURCHASE PLAN") and subscribes to purchase shares of the Company's Common Stock
in accordance with this Subscription Agreement and the Employee Stock Purchase
Plan.

         2. I hereby authorize payroll deductions from each paycheck in the
amount of ____% of my Compensation on each payday (not to exceed 10%) during the
Offering Period in accordance with the Employee Stock Purchase Plan. (Please
note that no fractional percentages are permitted.)

         3. I understand that said payroll deductions shall be accumulated for
the purchase of shares of Common Stock at the applicable Purchase Price
determined in accordance with the Employee Stock Purchase Plan. I understand
that if I do not withdraw from an Offering Period, any accumulated payroll
deductions will be used to automatically exercise my option.

         4. I have received a copy of the complete Employee Stock Purchase Plan.
I understand that my participation in the Employee Stock Purchase Plan is in all
respects subject to the terms of the Plan. I understand that my ability to
exercise the option under this Subscription Agreement is subject to stockholder
approval of the Employee Stock Purchase Plan.

         5. Shares purchased for me under the Employee Stock Purchase Plan
should be issued in the name(s) of (Employee or Employee and Spouse only):
________________.

         6. I understand that if I dispose of any shares received by me pursuant
to the Plan within 2 years after the Enrollment Date (the first day of the
Offering Period during which I purchased such shares) or one year after the
Exercise Date, I will be treated for federal income tax purposes as having
received ordinary income at the time


<PAGE>   12


of such disposition in an amount equal to the excess of the fair market value of
the shares at the time such shares were purchased by me over the price which I
paid for the shares. I HEREBY AGREE TO NOTIFY THE COMPANY IN WRITING WITHIN 30
DAYS AFTER THE DATE OF ANY DISPOSITION OF MY SHARES AND I WILL MAKE ADEQUATE
PROVISION FOR FEDERAL, STATE OR OTHER TAX WITHHOLDING OBLIGATIONS, IF ANY, WHICH
ARISE UPON THE DISPOSITION OF THE COMMON STOCK. The Company may, but will not be
obligated to, withhold from my compensation the amount necessary to meet any
applicable withholding obligation including any withholding necessary to make
available to the Company any tax deductions or benefits attributable to sale or
early disposition of Common Stock by me. If I dispose of such shares at any time
after the expiration of the 2-year and 1-year holding periods, I understand that
I will be treated for federal income tax purposes as having received income only
at the time of such disposition, and that such income will be taxed as ordinary
income only to the extent of an amount equal to the lesser of (1) the excess of
the fair market value of the shares at the time of such disposition over the
purchase price which I paid for the shares, or (2) 15% of the fair market value
of the shares on the first day of the Offering Period. The remainder of the
gain, if any, recognized on such disposition will be taxed as capital gain.

         7. I hereby agree to be bound by the terms of the Employee Stock

3.2      Provision of Akamai Services [**]. Subject to Microsoft's performance
         of its obligations under Sections 2.1 through 2.4, Akamai agrees to
         perform the following obligations:

         (a)      Akamai agrees to provide, during the [**] commencing on the
                  Effective Date, Akamai Services [**] to be comprised of
                  Broadband Streaming Media delivery services [**] to each [**]
                  in the Broadband Streaming Initiative; provided, however, that
                  such obligation shall not extend beyond [**] the Term of this
                  Agreement, and the aggregate value of [**] Akamai Services
                  that Akamai agrees to provide for and as used by [**], will
                  not exceed[**], as such usage is calculated in accordance with
                  Exhibit A. Akamai will use commercially reasonable efforts to
                  notify Microsoft in writing at least [**] before it
                  anticipates [**] exceeding the foregoing maximum value of the
                  relevant Akamai Services. Notwithstanding the foregoing,
                  Akamai's obligation under this Section 3.2(a) will be subject
                  to (i) notification by Microsoft as to [**]; (ii) execution of
                  Akamai's standard services agreement [**]; and (iii) there
                  being at least three (3) [**] will use during any [**] more
                  than [**] of the [**] Akamai Services that Akamai agrees to
                  provide pursuant to this Section 3.2(a).

         (b)      At Microsoft's request [**] to Microsoft [**]. Akamai will
                  install hardware and equipment, as well as copies of the
                  Akamai Software, and provide its standard level of service
                  related to such hardware and equipment and for such software
                  during the Term [**] in its discretion [**]. As a condition to
                  Akamai performing the foregoing obligations, each [**] will
                  first agree to comply with a separate written agreements with
                  Akamai and/or its resellers or other licensees with respect to
                  installation and support of the hardware, equipment and Akamai
                  Software, and nothing in this Agreement shall be deemed to
                  authorize Microsoft to install and/or support such hardware,
                  equipment or copies of the Akamai Software.

         (c)      In addition to the obligations of Akamai under Sections 3.2(a)
                  and (b), as contemplated in Section 2.1 above, Microsoft shall
                  be entitled to [**] and thereby obtain Akamai Services, at
                  Microsoft's sole discretion, (i) for the [**] in accordance

                  or (ii) for Microsoft to obtain other services offered by

         Akamai, including without limitation Akamai's FreeFlow services and any
         new versions or successors thereto, subject to [**] entering into
         Akamai's standard services agreement. In the event that Microsoft
         authorizes Akamai to provide Akamai Services pursuant to the terms set
         forth in Exhibit A) Microsoft agrees to pay Akamai for such Akamai
         Services in accordance with Akamai's then-current pricing to third
         parties [**] to those being [**] by Microsoft in connection with the
         [**] under this Agreement.

                  [**] beginning on the day [**] of each [**] may be [**] for
                  use during the [**] and a [**] of each such [**] may be [**]
                  for use during the [**] all in the same manner as described in
                  Section 3.2(c)(i) above, with the result being that the last
                  date on which Microsoft [**] might potentially use [**] under
                  this Section 3.2(c), [**] have been [**] as provided for
                  herein, [**]; and

                           (iii) notwithstanding subparagraph (ii) [**] above,

        entitled to perform under any contractual obligation to which it is

6.       CONFIDENTIALITY

6.1      Each party shall protect the other's Confidential Information from
         unauthorized dissemination and use with the same degree of care that
         such party uses to protect its own like information and in no event
         using less than a reasonable degree of care. Neither party will use the
         other's Confidential Information for purposes other than those
         necessary to directly further the purposes of this Agreement. Neither
         party will disclose to third parties the other's Confidential
         Information without the prior written consent of the other party.
         Except as expressly provided in this Agreement, no ownership or license
         rights are granted in any Confidential Information. The other
         provisions of this Agreement notwithstanding, either party will be
         permitted to disclose the Confidential Information to their outside
         legal and financial advisors; and to the extent required by applicable
         law, provided however that before making any such required filing or
         disclosure, the disclosing party shall first give written notice of the
         intended disclosure to the other party, within a reasonable time from
         the time disclosure is requested and in any event prior to the time
         when disclosure is to be made, and the disclosing party will exercise
         best efforts, in cooperation with and at the expense of the other
         party, consistent with reasonable time constraints, to obtain
         confidential treatment for all non-public and sensitive provisions of
         this Agreement, including without limitation dollar amounts and other
         numerical information.

6.2      The parties' obligations of confidentiality under this Agreement shall
         not be construed to limit either party's right to independently develop
         or acquire products without use of the other party's Confidential
         Information. Further, either party shall be free to use for any purpose
         the residuals resulting from access to or work with such Confidential
         Information, provided that such party shall maintain the
         confidentiality of the Confidential Information as provided herein. The
         term "residuals" means information in non-tangible form, which may be
         retained by persons who have had rightful and good faith access to the
         Confidential Information, including ideas, concepts, know-how or
         techniques contained therein. Neither party shall have any obligation
         to limit or restrict the assignment of such persons or to pay royalties
         for any work resulting from the use of residuals. However, the
         foregoing shall not be deemed to grant to either party a license under
         the other party's copyrights or patents.

         attributable to such Akamai Claims; provided, however, that Microsoft
         shall: (a) provide Akamai reasonably prompt notice in writing of any
         such Akamai Claims and permit Akamai, through counsel chosen by Akamai,
         to answer and defend and have exclusive control over, subject to
         Section 8.2, the answer and defense of such Akamai Claims; and (b)
         provide the entity defending such claim information, assistance and
         authority, at such entity's expense, to help defend such Akamai Claims.
         Akamai will not be responsible for any settlement made by Microsoft
         without Akamai's written permission, which permission will not be
         unreasonably withheld or delayed. Reasonable withholding of permission
         may be based upon, among other factors, editorial and business
         concerns. Akamai will consult with Microsoft on Akamai's choice of
         counsel under this Section 8.1. In the event Microsoft receives any
         Akamai Claim or Microsoft has reason to believe it may be subject to
         any Akamai Claim, Microsoft shall be entitled, upon written notice to
         Akamai, to suspend performance under this Agreement with respect to the
         applicable Akamai Service(s), Akamai Web Site or Content thereon until
         Akamai has taken steps to Microsoft's reasonable satisfaction in order
         to address the alleged infringement. If Akamai does not take
         satisfactory steps to address the alleged infringement within [**]
         after Microsoft delivers such a notice of suspension, then Microsoft in
         its discretion may terminate this Agreement upon written notice to
         Akamai and such termination shall be deemed to be a termination for
         cause for purposes of Section 9.

8.2      Settlement by Akamai. Unless Akamai obtains for Microsoft a complete
         release of all Akamai Claims thereunder, Akamai may not settle any
         Akamai Claim under Section 8.1 on Microsoft's behalf without first
         obtaining Microsoft's written permission, which permission

<PAGE>   16
          Confidential materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


         will not be unreasonably withheld or delayed. Reasonable withholding of
         permission may be based upon, among other factors, the ability for
         Microsoft to ship any product. In the event Akamai and Microsoft agree
         to settle an Akamai Claim, both parties agree not to disclose terms of
         the settlement without first obtaining the other party's written
         permission, which will not be unreasonably withheld or delayed.

8.3      Indemnification by Microsoft. Microsoft shall, at its expense and
         Akamai's request, defend any claim or action brought by a third party
         against Akamai, or Akamai's affiliates, directors, or officers, to the
         extent it is based upon a claim relating to Microsoft's promotion of
         any Akamai Services or Microsoft's promotional activities regarding the
         Broadband Streaming Initiative (all such claims or actions being
         referred to hereinafter as "Microsoft Claims"), and Microsoft will
         indemnify and hold Akamai harmless from and against any costs, damages
         and fees reasonably incurred by Akamai, including but not limited to
         fees of outside attorneys and other professionals, that are
         attributable to such Microsoft Claims; provided, however, that Akamai
         shall: (a) provide Microsoft reasonably prompt notice in writing of any
         such Microsoft Claims and permit Microsoft, through counsel chosen by
         Microsoft, to answer and defend and have exclusive control, subject to
         Section 8.4, over the answer and defense of such Microsoft Claims; and
         (b) provide Microsoft such claim information, assistance and authority,
         at Microsoft's expense, to help defend such Microsoft Claims. Microsoft
         will not be responsible for any settlement made by Akamai without
         Microsoft's written permission, which permission will not be
         unreasonably withheld or delayed. Reasonable withholding of permission
         may be based upon, among other factors, editorial and business
         concerns. In the event Akamai receives any Microsoft Claim or Akamai
         has reason to believe it may be subject to any Microsoft Claim, Akamai
         shall be entitled, upon written notice to Microsoft, to suspend
         performance under this Agreement with respect to the applicable
         obligations of Akamai under Section until Microsoft has taken steps to
         Akamai's reasonable satisfaction in order to address the alleged
         infringement. If Microsoft does not take satisfactory steps to address
         the alleged infringement [**] after Akamai delivers such a notice of
         suspension, then Akamai in its discretion may terminate this Agreement
         upon written notice to Microsoft and such termination shall be deemed
         to be a termination for cause for purposes of Section 9.

8.4      Settlement by Microsoft. Unless Microsoft obtains for Akamai a complete
         release of all Microsoft Claims thereunder, Microsoft may not settle
         any Microsoft Claim under Section 8.3 on Akamai's behalf without first
         obtaining Akamai's written permission, which permission will not be
         unreasonably withheld or delayed. Reasonable withholding of permission
         may be based upon, among other factors, the ability for Akamai to
         provide any Akamai Services. In the event Microsoft and Akamai agree to
         settle a Microsoft Claim,

                      Microsoft Confidential & Proprietary

          Confidential materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.



         both parties agree not to disclose terms of the settlement without
         first obtaining the other party's written permission, which will not be
         unreasonably withheld or delayed.


9.       TERMINATION

9.1      Termination By Either Party. Either party may suspend performance
         and/or terminate this Agreement only as expressly provided elsewhere in
         this Agreement or:

         (a)      Immediately upon written notice at any time, if the other
                  party is in material breach of any material warranty, term,
                  condition or covenant of this Agreement, other than those
                  contained in Section 6, and fails to cure that breach [**]
                  after written notice thereof; or

         (b)      Immediately upon written notice at any time, if the other
                  party is in material breach of Section 6.

9.2      Effect of Termination.

         (a)      Neither party shall be liable to the other for damages of any
                  sort resulting solely from terminating this Agreement in
                  accordance with its terms.

         (b)      Termination of this Agreement shall not affect any other
                  agreement between the parties.

         (c)      Should either Akamai or Microsoft terminate for cause pursuant
                  to Section 8.1, 8.3, 9.1(a), or 9.1(b), neither party shall
                  have any further obligations to the other under Sections
                  2.1-2.5, Section 3.1-3.5, or Section 4, with the exception
                  that [**] shall be entitled to require [**] then having been
                  [**] as not (as of the termination date) [**] other services
                  for the parties and purposes specified in Section 2.1 and
                  Exhibit A. Alternatively, in the event Microsoft terminates
                  this Agreement for cause pursuant to Section 8.1, 9.1(a) or
                  9.1(b), [**] may elect [**] in accordance with the [**]
                  schedule set forth in Section 3.2(c), [**] then having been
                  [**] and which has not been [**] of such [**] still
                  outstanding as of the date of termination. Without limiting
                  the generality of the foregoing, Microsoft will have no
                  obligation following termination of this Agreement [**]
                  provide any further services to Akamai under Section 2 of this
                  Agreement, and, except as provided above, Akamai shall have no
                  obligation following termination of this Agreement to provide
                  any further services to Microsoft [**].

9.3      Survival. In the event of termination or expiration of this Agreement
         for any reason, Sections 1, 2.6, 3.6 and 5-11 shall survive termination
         and continue in effect in accordance with their terms.


10.      LIMITATION OF LIABILITIES

IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT,
INCIDENTAL, PUNITIVE OR SPECIAL DAMAGES WHATSOEVER, INCLUDING, WITHOUT
LIMITATION, DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION, LOSS OF
BUSINESS INFORMATION, AND THE LIKE, ARISING OUT OF THIS AGREEMENT OR THE USE OF

INFORMATION, CONTENT, OR SERVICES, EVEN IF A PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

THIS SECTION SHALL NOT APPLY TO SECTION 6 (REGARDING CONFIDENTIALITY),
NOR TO THE INDEMNITY OBLIGATIONS WITH RESPECT TO THIRD PARTY CLAIMS
AS PROVIDED IN SECTION 8 OF THIS AGREEMENT.

11.2     Independent Parties. Nothing in this Agreement shall be construed as
         creating an employer-employee relationship, an agency relationship, a
         partnership, or a joint venture between the parties.

11.3     Governing Law. This Agreement will be governed by the laws of the State
         of Washington, without reference to the conflict of law principles
         thereof. Any action or litigation concerning this Agreement brought by
         Akamai will take place exclusively in the federal or state courts in
         King County, Washington. Any action or litigation concerning this
         Agreement brought by Microsoft will take place exclusively in the
         federal or state courts in Boston, Massachusetts. The parties expressly
         consent to jurisdiction of and venue in the courts specified in the
         foregoing sentences and waive all defenses of lack of personal
         jurisdiction and forum non conveniens with respect to such courts. Each
         party hereby agrees to service of process by mail or other method
         acceptable under the laws of the State of Washington.

11.4     Attorneys' Fees. In any action or suit to enforce any right or remedy
         under this Agreement or to interpret any provision of this Agreement,
         the prevailing party shall be entitled to recover its costs, including
         reasonable attorneys' fees.

11.5     Dispute Resolution Procedures Related to Meeting Performance Criteria.
         In the event a dispute between Akamai and Microsoft arises under
         Section 2.5 of the Agreement, the parties shall attempt to settle such
         dispute through consultation and negotiation between the responsible
         Microsoft contact and Akamai contact in good faith and a spirit of
         mutual cooperation. If the respective contacts are unable to resolve
         the dispute, it shall be referred to a conflict resolution committee
         comprised of one representative designated by each party. Except where
         prevented from doing so by the matter in dispute, the parties agree to
         continue performing their obligations under this Agreement while any
         good faith dispute is being resolved unless and until such obligations
         are terminated by the termination or expiration of any project or this
         Agreement.

11.6     Assignment. This Agreement and any rights or obligations hereunder may
         not be assigned by either party (including without limitation via
         merger, stock purchase, a sale of substantially all assets, or
         otherwise by operation of law) without the other party's prior written
         approval, which approval will not be unreasonably withheld or delayed.
         Any attempted assignment, sub-license, transfer, encumbrance or other
         disposal which has not

                      Microsoft Confidential & Proprietary
                                     Page 19
<PAGE>   20
         been so approved will be void and will constitute a material default
         and breach of this Agreement for which the non-breaching party may
         terminate this Agreement in accordance with Section 9.1. Except as
         otherwise provided, this Agreement will be binding upon and inure to
         the benefit of the parties' successors and lawful assigns.

11.7     Force Majeure. Neither party shall be liable to the other under this
         Agreement for any delay or failure to perform its obligations under
         this Agreement if such delay or failure arises from any cause(s) beyond
         such party's reasonable control, including by way of example labor
         disputes, strikes, acts of God, floods, fire, lightning, utility or
         communications failures, earthquakes, vandalism, war, acts of
         terrorism, riots, insurrections, embargoes, or laws, regulations or
         orders of any governmental entity.

11.8     Construction. If for any reason a court of competent jurisdiction finds
         any provision of this Agreement, or portion thereof, to be
         unenforceable, that provision of the Agreement will be enforced to the
         maximum extent permissible so as to effect the intent of the parties,
         and the remainder of this Agreement will continue in full force and
         effect. Failure by either party to enforce any provision of this
         Agreement will not be deemed a waiver of future enforcement of that or
         any other provision. This Agreement has been negotiated by the parties
         and their respective counsel and will be interpreted fairly in
         accordance with its terms and without any strict construction in favor
         of or against either party.

11.9     Execution in Counterparts and by Facsimile. This Agreement may be
         executed in one or more counterparts, each of which will be deemed an
         original, but all of which together will constitute one and the same
         instrument. A facsimile copy of a signed counterpart shall be treated
         the same as a signed original.

11.10    Entire Agreement. This Agreement does not constitute an offer by
         Microsoft and it shall not be effective until signed by both parties.
         This Agreement constitutes the entire agreement between the parties
         with respect to the subject matter hereof and merges all prior and
         contemporaneous communications. It shall not be modified except by a
         written agreement dated subsequent to the date of this Agreement and
         signed on behalf of Akamai and Microsoft by their respective duly
         authorized representatives.
