5 - -------------------------------------------------------------------------------- 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 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 July 31, 1999, we had 900 Akamai servers deployed in 15 countries across 25 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 30. - -------------------------------------------------------------------------------- 3

8 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. 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. 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 6

9 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 July 31, 1999, our network consisted of 900 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. 7

10 As competition in the Internet content delivery market continues to intensify, new solutions will come to market. We are aware of at least one company that is focusing 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. 8

11 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 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 have chosen to 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 expenses increase more than we expect or cannot be reduced in the event of lower revenue, our business will be materially and adversely affected. 9

12 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. 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 10

13 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 143 on August 11, 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 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. 11

14 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. 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 12

15 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 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 13

16 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 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 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. 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. 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 70.2% 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. 14

17 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 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. 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. 15

18 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. 16

19 USE OF PROCEEDS We estimate that the net proceeds from our sale of the 6,000,000 shares of common stock will be approximately $93.7 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 $107.9 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. 17

20 CAPITALIZATION The following table sets forth our capitalization as of June 30, 1999. The pro forma information gives effect to the conversion of all of our outstanding convertible preferred stock outstanding as of June 30, 1999. The pro forma as adjusted information reflects the issuance and sale of the 6,000,000 shares of common stock offered by us in this offering at an assumed initial public offering price of $17.00 per share. The outstanding share information excludes: - 11,191,100 shares of common stock issuable upon exercise of options and warrants outstanding as of June 30, 1999; - 13,639,600 shares of common stock reserved for future issuance under our 1998 Stock Incentive Plan as of June 30, 1999; - 145,195 shares of Series C convertible preferred stock issuable upon exercise of an outstanding option as of June 30, 1999, which are convertible into 908,339 shares of common stock; - 1,867,480 shares of Series E convertible preferred stock issued in August 1999, which are convertible into 3,734,960 shares of common stock; and - 985,545 shares of Series F convertible preferred stock issued in September 1999, which are convertible into 985,545 shares of common stock. This table should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our financial statements and accompanying notes and other financial data included elsewhere in this prospectus.

21 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 $129.5 million, or $1.59 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 $15.41 per share. The following table illustrates this per share dilution: Assumed initial public offering price per share............. $17.00 Pro forma net tangible book value per share before this offering............................................... $0.48 Increase in pro forma net tangible book value per share attributable to new investors.......................... 1.11 ----- Pro forma net tangible book value per share after this offering.................................................. 1.59 ------ Dilution per share to new investors......................... $15.41 ====== 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 by us: SHARES PURCHASED TOTAL CONSIDERATION AVERAGE --------------------- ----------------------- PRICE PER NUMBER PERCENT AMOUNT PERCENT SHARE ---------- ------- ------------ ------- --------- Existing stockholders................ 75,301,004 92.6% $ 44,169,165 30.2% $ 0.59 New investors........................ 6,000,000 7.4 102,000,000 69.8 17.00 ---------- ----- ------------ ----- Total...................... 81,301,004 100.0% $146,169,165 100.0% ========== ===== ============ ===== 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 $1.51 and total dilution per share to new investors would be $15.49. If the underwriters' over-allotment option is exercised in full, the number of shares held by new investors will increase to 6,900,000 shares, or 8.4% of the total number of shares of common stock outstanding after this offering. 19

23 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 FreeFlow ISP 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. 21

24 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 $3.3 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. 22

25 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 23

26 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. 24

27 BUSINESS 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 July 31, 1999, we had 900 Akamai servers deployed in 15 countries across 25 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 25

28 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 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. 26

29 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 900 servers deployed in 15 countries across 25 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. 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 Web content 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 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 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 FreeFlow ISP 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 planning to expand 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 Internet-centric companies, will help to create a competitive advantage in our market. 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 27

30 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. 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. 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, 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 SERVICE 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. We have recently begun to introduce commercially a service that enables the delivery of streaming audio and video over our network. FreeFlow 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. Our FreeFlow service is backed by Akamai's 100% 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; - 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. 28

31 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. 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. 29

32 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. 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. 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. 30

33 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.

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. 31

34 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 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 bandwith 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 indirect distribution channels. As of August 11, 1999, we had 12 employees in our sales and distribution organization. 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 August 11, 1999, we had three employees in our partner 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 August 11, 1999, we had 12 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 August 11, 1999, we had six employees in our customer service and support 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 August 11, 1999, we had 10 employees in our marketing organization. NETWORK DEPLOYMENT As of July 31, 1999, our network was comprised of 900 servers in 15 countries across 25 telecommunication networks. Some of the telecommunications networks across which Akamai servers are deployed include: AboveNet Communications, AT&T, Digex, Exodus Communications, GTE 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 FreeFlow ISP program. Under this program, we offer use of our servers to Internet service providers. In exchange, we do not pay for rack space to house our servers or bandwidth to deliver 32

35 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 our network by 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 August 11, 1999, we had 47 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 for our new services under development, including streaming media. 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. 33

36 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 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. 34

37 EMPLOYEES As of August 11, 1999, we had a total of 130 full-time employees and 13 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. BOARD OF ADVISORS Our board of advisors consists of individuals with recognized expertise in the Internet, networking, science and entertainment fields. Members of our board of advisors provide guidance to our management and board of directors about technology standards and marketplace needs to assist us with our business and strategy.

EXECUTIVE COMPENSATION The following table sets forth the compensation paid by us, for services rendered for the period from August 20, 1998, the date of our inception, to December 31, 1998, to the person who acted in the capacity of chief executive officer during that period. None of our other executive officers who held office as of December 31, 1998 met the definition of "highly compensated" within the meaning of the Securities and Exchange Commission's executive compensation disclosure rules. In the table below, columns required by the regulations of the Securities and Exchange Commission have been omitted where no information was required to be disclosed under those columns. SUMMARY COMPENSATION TABLE ANNUAL COMPENSATION ------------------- NAME AND PRINCIPAL POSITION SALARY($) - --------------------------- ------------------- Daniel M. Lewin............................................. $ 30,000 President(1) - ------------ (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. 40

43 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 more than 20 hours per week for more than five months in a calendar year; - Who were employed by us prior to , 1999 for the first offering period or for subsequent offering periods, who have been employed by us for at least days prior to enrolling; and - Who are employed on the first day of a designated payroll purchase period 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 following exercise and automatically re-enrolled in a new offering period.

49 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 22, 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 14,195,561 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 88,318,428 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 47

50 - 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. 48

51 SHARES ELIGIBLE FOR FUTURE SALE Upon completion of this offering, based on the number of shares outstanding at September 22, 1999, we will have 88,318,428 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 82,318,428 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.

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 900,000 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 up to percent of the shares of common stock to be issued by us and offered in this offering for sale, at the price per share in this offering, to directors, officers, employees, business associates and related persons of Akamai. The underwriters have also reserved for sale, at the initial public offering price, up to 300,000 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." 51

54 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. 52

62 AKAMAI TECHNOLOGIES, INC. 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. F-7

63 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 Company's FreeFlow ISP program, the Company provides FreeFlow 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

64 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, F-9

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.

66 AKAMAI TECHNOLOGIES, INC. NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) 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. 6. COMMITMENTS: LEASES The Company leases its facilities and certain equipment under operating leases.

The leases expire at various dates through April 30, 2004 and generally require the payment of real estate taxes, insurance, maintenance, and operating costs. The Company also leases certain equipment under capital leases. The minimum aggregate future obligations under noncancelable leases and equipment loans as of June 30, 1999 are as follows: CAPITAL LEASES (INCLUDING OPERATING EQUIPMENT YEAR ENDING LEASES LOAN) - ----------- ---------- ---------- 1999........................................................ $ 261,841 $ 288,353 2000........................................................ 519,404 576,702 2001........................................................ 519,404 572,621 2002........................................................ 519,404 160,123 2003........................................................ 224,255 -- ---------- ---------- Total....................................................... $2,044,308 1,597,799 ========== Less interest...............................................

The warrants were exercisable upon issuance and expire on January 26, 2002. The Company estimated the value of the warrants to be $25,351 at the date of issuance, which has been recorded as additional paid-in capital and reduced the carrying value of the equipment loan. The fair value was estimated using the Black-Scholes model with the following assumptions: dividend yield of F-11

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. 10.

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. F-17

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

77 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 15.

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 to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares, or any person controlling such Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities, -15-

17 unless such failure is the result of noncompliance by the Company with Section 6(a) hereof. (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b), such person (the "INDEMNIFIED PARTY") shall promptly notify the person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Morgan Stanley, in the case of parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. -16-

18 (d) To the extent the indemnification provided for in Section 7(a) or 7(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 7(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. (e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent -17-

19 misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. (f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares. 8. DIRECTED SHARE PROGRAM INDEMNIFICATION. (a) The Company agrees to indemnify and hold harmless Morgan Stanley and its affiliates and each person, if any, who controls Morgan Stanley and its affiliates within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act ("Morgan Stanley Entities"), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant has agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of Morgan Stanley Entities. (b) In case any proceeding (including any governmental investigation) shall be instituted involving any Morgan Stanley Entity in respect of which indemnity may be sought pursuant to Section 8(a), the Morgan Stanley Entity seeking indemnity shall promptly notify the Company in writing and the Company, upon request of the Morgan Stanley Entity, shall retain counsel reasonably satisfactory to the Morgan Stanley Entity to represent the Morgan Stanley Entity and any other the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Morgan Stanley Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Morgan Stanley Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Company and the Morgan Stanley Entity and representation of both parties by the same counsel would be inappropriate due to actual -18-

20 or potential differing interests between them. The Company shall not, in respect of the legal expenses of the Morgan Stanley Entities in connection with any proceeding or related proceedings the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Morgan Stanley Entities. Any such firm for the Morgan Stanley Entities shall be designated in writing by Morgan Stanley. The Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the Morgan Stanley Entities from and against any loss or liability by reason of such settlement or judgment. The Company shall not, without the prior written consent of Morgan Stanley, effect any settlement of any pending or threatened proceeding in respect of which any Morgan Stanley Entity is or could have been a party and indemnity could have been sought hereunder by such Morgan Stanley Entity, unless such settlement includes an unconditional release of the Morgan Stanley Entities from all liability on claims that are the subject matter of such proceeding. (c) To the extent the indemnification provided for in Section 8(a) is unavailable to a Morgan Stanley Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company, in lieu of indemnifying the Morgan Stanley Entity thereunder, shall contribute to the amount paid or payable by the Morgan Stanley Entity as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Morgan Stanley Entities on the other hand from the offering of the Directed Shares or (ii) if the allocation provided by clause 8(c)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(c)(i) above but also the relative fault of the Company on the one hand and of the Morgan Stanley Entities on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and of the Morgan Stanley Entities on the other hand in connection with the offering of the Directed Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Shares (before deducting expenses) and the total underwriting discounts and commissions received by the Morgan Stanley Entities for the Directed Shares, bear to the aggregate Public Offering Price of the Shares. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact, the relative fault of the Company on the one hand and the Morgan Stanley Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by the Company or by the Morgan Stanley Entities and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. (d) The Company and the Morgan Stanley Entities agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata -19-

21 allocation (even if the Morgan Stanley Entities were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(c). The amount paid or payable by the Morgan Stanley Entities as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by the Morgan Stanley Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Morgan Stanley Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Shares distributed to the public were offered to the public exceeds the amount of any damages that such Morgan Stanley Entity has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Morgan Stanley Entity at law or in equity. (e) The indemnity and contribution provisions contained in this Section 8 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Morgan Stanley Entity or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Directed Shares. 9. TERMINATION. This Agreement shall be subject to termination by notice given by you to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and (b) in the case of any of the events specified in clauses 8(a)(i) through 8(a)(iv), such event, singly or together with any other such event, makes it, in your judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Prospectus. 10. EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more -20-

22 than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. 11. COUNTERPARTS. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 12. APPLICABLE LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. -21-

25 EXHIBIT A FORM OF LOCK-UP September __, 1999 Morgan Stanley & Co. Incorporated Donaldson, Lufkin & Jenrette Salomon Smith Barney Thomas Weisel Partners LLC c/o Morgan Stanley & Co. Incorporated 1585 Broadway New York, NY 10036 Dear Sirs and Mesdames: The undersigned understands that Morgan Stanley & Co. Incorporated ("MORGAN STANLEY") proposes to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") with Akamai Technology, Inc., a Delaware corporation (the "COMPANY") providing for the public offering (the "PUBLIC OFFERING") by the several Underwriters, including Morgan Stanley (the "UNDERWRITERS"), of ______________ shares (the "SHARES") of the common stock, par value $0.01 per share, of the Company (the "COMMON STOCK"). To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, the undersigned will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering (the "Prospectus"), (1) 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 (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 Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to the sale of any Shares to the Underwriters pursuant to the Underwriting Agreement or transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering. In addition, the undersigned agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. Notwithstanding the foregoing (i) gifts and transfers by will or intestacy or (ii) transfers to (A) the undersigned's members, partners, affiliates or immediate family or (B) a trust, the beneficiaries of which are the undersigned and/or members of the undersigned's immediate family, shall not be prohibited by this agreement; provided, that (x) the donee or transferee agrees in writing to be bound by the foregoing in the same manner as it applies to the undersigned and (y) if the donor or transferor is a reporting person subject to Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange Act"), any gifts or transfers made in accordance with this paragraph shall not require such person to, and such person shall not voluntarily, file a report of such transaction on Form 4 under the Exchange Act. "Immediate family" shall mean spouse, lineal descendants, father, mother, brother or sister of the transferor and father, mother, brother or sister of the transferor's spouse. Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters. This agreement shall automatically terminate on the date that the Underwriting Agreement is terminated, in the event that the Underwriters do not purchase the Shares and the Underwriting Agreement is terminated pursuant to its terms. Very truly yours, --------------------------------- (Name) --------------------------------- (Address) -1-

3 FIFTH. The name and mailing address of the sole incorporator are as follows: NAME MAILING ADDRESS ---- --------------- Daniel M. Lewin 15 Charlesden Park Newtonville, MA 02460. SIXTH. In furtherance of and not in limitation of powers conferred by statute, it is further provided: 1. Election of directors need not be by written ballot. 2. The Board of Directors is expressly authorized to adopt, amend or repeal the By-Laws of the Corporation. SEVENTH. Except to the extent that the General Corporation Law of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty, no director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability. No amendment to or repeal of this provision shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment. EIGHTH. 1. Actions, Suits and Proceedings Other than by or in the Right of the Corporation. The Corporation shall indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that he is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an "Indemnitee"), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, 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 Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in, or not opposed to,

4 the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. Notwithstanding anything to the contrary in this Article, except as set forth in Section 7 below, the Corporation shall not indemnify an Indemnitee seeking indemnification in connection with a proceeding (or part thereof) initiated by the Indemnitee unless the initiation thereof was approved by the Board of Directors of the Corporation. Notwithstanding anything to the contrary in this Article, the Corporation shall not indemnify an Indemnitee to the extent such Indemnitee is reimbursed from the proceeds of insurance, and in the event the Corporation makes any indemnification payments to an Indemnitee and such Indemnitee is subsequently reimbursed from the proceeds of insurance, such Indemnitee shall promptly refund such indemnification payments to the Corporation to the extent of such insurance reimbursement. 2. Actions or Suits by or in the Right of the Corporation. The Corporation shall indemnify any Indemnitee who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys' fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, 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 Corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of Delaware shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses (including attorneys' fees) which the Court of Chancery of Delaware shall deem proper. 3. Indemnification for Expenses of Successful Party. Notwithstanding the other provisions of this Article, to the extent that an Indemnitee has been successful, on the merits or otherwise, in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article, or in defense of any claim, issue or matter therein, or on appeal from any such action, suit or proceeding, he shall be indemnified against all expenses (including attorneys' fees) actually and reasonably incurred by him or on his behalf in connection therewith. Without limiting the foregoing, if any action, suit or proceeding is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an

5 adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the Indemnitee 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 Corporation, and (v) with respect to any criminal proceeding, an adjudication that the Indemnitee had reasonable cause to believe his conduct was unlawful, the Indemnitee shall be considered for the purposes hereof to have been wholly successful with respect thereto. 4. Notification and Defense of Claim. As a condition precedent to his right to be indemnified, the Indemnitee must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving him for which indemnity will or could be sought. With respect to any action, suit, proceeding or investigation of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to the Indemnitee. After notice from the Corporation to the Indemnitee of its election so to assume such defense, the Corporation shall not be liable to the Indemnitee for any legal or other expenses subsequently incurred by the Indemnitee in connection with such claim, other than as provided below in this Section 4. The Indemnitee shall have the right to employ his own counsel in connection with such claim, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of the Indemnitee unless (i) the employment of counsel by the Indemnitee has been authorized by the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and the Indemnitee in the conduct of the defense of such action or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, in each of which cases the fees and expenses of counsel for the Indemnitee shall be at the expense of the Corporation, except as otherwise expressly provided by this Article. The Corporation shall not be entitled, without the consent of the Indemnitee, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for the Indemnitee shall have reasonably made the conclusion provided for in clause (ii) above. 5. Advance of Expenses. Subject to the provisions of Section 6 below, in the event that the Corporation does not assume the defense pursuant to Section 4 of this Article of any action, suit, proceeding or investigation of which the Corporation receives notice under this Article, any expenses (including attorneys' fees) incurred by an Indemnitee in defending a civil or criminal action, suit, proceeding or investigation or any appeal therefrom shall be paid by the Corporation in advance of the final disposition of such matter; provided, however, that the payment of such expenses incurred by an Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined

6 that the Indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article. Such undertaking shall be accepted without reference to the financial ability of the Indemnitee to make such repayment. 6. Procedure for Indemnification. In order to obtain indemnification or advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the Indemnitee shall submit to the Corporation a written request, including in such request such documentation and information as is reasonably available to the Indemnitee and is reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification or advancement of expenses. Any such indemnification or advancement of expenses shall be made promptly, and in any event within 60 days after receipt by the Corporation of the written request of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the Corporation determines within such 60-day period that the Indemnitee did not meet the applicable standard of conduct set forth in Section 1 or 2, as the case may be. Such determination shall be made in each instance by (a) a majority vote of the directors of the Corporation consisting of persons who are not at that time parties to the action, suit or proceeding in question ("disinterested directors"), whether or not a quorum, (b) a majority vote of a quorum of the outstanding shares of stock of all classes entitled to vote for directors, voting as a single class, which quorum shall consist of stockholders who are not at that time parties to the action, suit or proceeding in question, (c) independent legal counsel (who may, to the extent permitted by law, be regular legal counsel to the Corporation), or (d) a court of competent jurisdiction. 7. Remedies. The right to indemnification or advances as granted by this Article shall be enforceable by the Indemnitee in any court of competent jurisdiction if the Corporation denies such request, in whole or in part, or if no disposition thereof is made within the 60-day period referred to above in Section 6. Unless otherwise required by law, the burden of proving that the Indemnitee is not entitled to indemnification or advancement of expenses under this Article shall be on the Corporation. Neither the failure of the Corporation to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because the Indemnitee has met the applicable standard of conduct, nor an actual determination by the Corporation pursuant to Section 6 that the Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the Indemnitee has not met the applicable standard of conduct. The Indemnitee's expenses (including attorneys' fees) incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such proceeding shall also be indemnified by the Corporation. 8. Subsequent Amendment. No amendment, termination or repeal of this Article or of the relevant provisions of the General Corporation Law of Delaware or any other applicable laws shall affect or diminish in any way the rights of any Indemnitee to indemnification under the provisions hereof with respect to any action,

7 suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal. 9. Other Rights. The indemnification and advancement of expenses provided by this Article shall not be deemed exclusive of any other rights to which an Indemnitee seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), agreement or vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in any other capacity while holding office for the Corporation, and shall continue as to an Indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of the Indemnitee. Nothing contained in this Article shall be deemed to prohibit, and the Corporation is specifically authorized to enter into, agreements with officers and directors providing indemnification rights and procedures different from those set forth in this Article. In addition, the Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article. 10. Partial Indemnification. If an Indemnitee is entitled under any provision of this Article to indemnification by the Corporation for some or a portion of the expenses (including attorneys' fees), judgments, fines or amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with any action, suit, proceeding or investigation and any appeal therefrom but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify the Indemnitee for the portion of such expenses (including attorneys' fees), judgments, fines or amounts paid in settlement to which the Indemnitee is entitled. 11. Insurance. The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) against any expense, liability or loss incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of Delaware. 12. Merger or Consolidation. If the Corporation is merged into or consolidated with another corporation and the Corporation is not the surviving corporation, the surviving corporation shall assume the obligations of the Corporation under this Article with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the date of such merger or consolidation.

8 13. Savings Clause. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each Indemnitee as to any expenses (including attorneys' fees), judgments, fines and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law. 14. Definitions. Terms used herein and defined in Section 145(h) and Section 145(i) of the General Corporation Law of Delaware shall have the respective meanings assigned to such terms in such Section 145(h) and Section 145(i). 15. Subsequent Legislation. If the General Corporation Law of Delaware is amended after adoption of this Article to expand further the indemnification permitted to Indemnitees, then the Corporation shall indemnify such persons to the fullest extent permitted by the General Corporation Law of Delaware, as so amended. NINTH. The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute and this Certificate of Incorporation, and all rights conferred upon stockholders herein are granted subject to this reservation.

13 SCHEDULE I AKAMAI TECHNOLOGIES, INC. DESIGNATION OF SERIES A CONVERTIBLE PREFERRED STOCK The series of Preferred Stock designated and known as "Series A Convertible Preferred Stock" shall consist of 1,100,000 shares. 1. Voting. 1A. General. Except as may be otherwise provided in these terms of the Series A Convertible Preferred Stock, in the Certificate of Incorporation (the "Certificate of Incorporation") of Akamai Technologies, Inc. (the "Corporation") or by law, the Series A Convertible Preferred Stock shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each share of Series A Convertible Preferred Stock shall entitle the holder thereof to such number of votes per share on each such action as shall equal the number of shares of Common Stock (including fractions of a share) into which each share of Preferred Stock is then convertible. 1B. Board Size. Subject to the provisions of paragraph 1C below, the Corporation shall not, without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, increase the maximum number of directors constituting the Board of Directors to a number in excess of seven (7). 1C. Board Seats. For so long as at least 50% of the shares of Series A Convertible Preferred Stock issued pursuant to the Purchase Agreement remains outstanding, the holders of the Series A Convertible Preferred Stock, voting as a separate series, shall be entitled to elect two (2) directors of the Corporation. At any meeting (or in a written consent in lieu thereof) held for the purpose of electing directors, the presence in person or by proxy (or the written consent) of the holders of at least a majority in interest of the then outstanding shares of Series A Convertible Preferred Stock shall constitute a quorum of the Series A Convertible Preferred Stock for the election of directors to be elected solely by the holders of the Series A Convertible Preferred Stock voting as a separate series. A vacancy in any directorship elected by the holders of the Series A Convertible Preferred Stock shall be filled only by the affirmative vote or written consent of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock. The directors to be elected by the holders of the Series A Convertible Preferred Stock, voting separately as one class, pursuant to this paragraph 1C, shall serve for terms extending from the date of their election and qualification until the time of the next succeeding annual meeting of stockholders and until their successors have been elected and qualified.

14 2. Dividends. No dividends shall be declared and set aside for any shares of the Series A Convertible Preferred Stock except in the event that the Board of Directors of the Corporation shall declare a dividend payable upon the then outstanding shares of the Common Stock of the Corporation, in which event the holders of the Series A Convertible Preferred Stock shall be entitled to the amount of dividends per share of Series A Convertible Preferred Stock as would be declared payable on the largest number of whole shares of Common Stock into which each share of Series A Convertible Preferred Stock held by each holder thereof could be converted pursuant to the provisions of Section 5 hereof, such number determined as of the record date for the determination of holders of Common Stock entitled to receive such dividend. All dividends declared upon the Preferred Stock shall be declared pro rata per share. 3. Liquidation, Dissolution and Winding-up. 3A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series A Convertible Preferred Stock shall be paid an amount equal to $7.60 per share plus, in the case of each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any class of stock ranking equally with the Series A Convertible Preferred Stock, and before any payment shall be made to the holders of any stock ranking on liquidation junior to the Series A Convertible Preferred Stock, such amount payable with respect to one share of Series A Convertible Preferred Stock being sometimes referred to as the "Series A Liquidation Preference Payment" and with respect to all shares of Series A Convertible Preferred Stock being sometimes referred to as the "Series A Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series A Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series A Convertible Preferred Stock shall be distributed to such holders of the Series A Convertible Preferred Stock pro rata, so that each holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 3B. Upon any Liquidation Event, immediately after the holders of Series A Convertible Preferred Stock and holders of any class of stock ranking equally with the Series A Convertible Preferred Stock have been paid in full pursuant to subsection 3A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Common Stock.

15 Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made, shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents, not less than 20 days prior to the payment date stated therein, to the holders of record of Series A Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. The (x) consolidation or merger of the Corporation into or with any other entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate thereof (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving Corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction), (y) the sale or transfer by the Corporation of all or substantially all its assets, or (z) the sale or transfer by the Corporation's stockholders of capital stock representing a majority of the outstanding capital stock of the Corporation shall be deemed to be a Liquidation Event within the meaning of the provisions of this paragraph 3 (subject to the provisions of this paragraph 3 and not the provisions of paragraph 5G hereof, unless 5G is elected in the following proviso), provided, however, that if the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock shall elect the benefits of the provisions of paragraph 5G in lieu of receiving payment in a Liquidation Event pursuant to this paragraph 3, then all holders of shares of Series A Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 5G in lieu of receiving payment pursuant to this Section 3. Whenever the distribution provided for in this paragraph 3 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 4. Restrictions. At any time when at least 50% of the shares of Series A Convertible Preferred Stock issued pursuant to the Purchase Agreement (as defined in Section 8(a) below) remain outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or the Certificate of Incorporation, without the written consent of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, the Corporation will not: (1) Consent to any Liquidation Event or merge or consolidate with or into, or permit any Subsidiary to merge or consolidate with or into, any other corporation, corporations, entity or entities (except a consolidation or merger into a Subsidiary or

16 merger in which the Corporation is the surviving corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger pursuant to which the aggregate consideration definitively and unconditionally payable to all of the stockholders of the Corporation is greater than $50 million); (2) Sell, abandon, transfer, lease or otherwise dispose of all or substantially all of its properties or assets (unless the aggregate consideration definitively and unconditionally payable to all of the stockholders of the Corporation as a result of any such transaction is greater than $50 million); (3) Amend, alter or repeal any provision of its Certificate of Incorporation or By-laws in a manner adverse to holders of the Series A Convertible Preferred Stock; (4) Create or authorize the creation of or issue any additional class or series of shares of stock unless the same ranks junior to or on parity with the Series A Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or increase the authorized amount of Series A Convertible Preferred Stock or increase the authorized amount of any additional class or series of shares of stock unless the same ranks junior to or on parity with the Series A Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or create or authorize any obligation or security convertible into shares of Series A Convertible Preferred Stock or into shares of any other class or series of stock unless the same ranks junior to or on parity with the Series A Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, whether any such creation, authorization or increase shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; (5) In any manner amend, alter or change the designations or the powers, preferences or rights, privileges or the restrictions of the Series A Convertible Preferred Stock, provided, however, that the authorization or creation of any shares of capital stock on parity with Series A Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event shall not require approval of holders of Series A Convertible Preferred Stock; (6) Purchase or redeem, or set aside any sums for the purchase or redemption of, or pay any dividend or make any distribution on, any shares of stock ranking on parity with or junior to the Series A Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, except for (i) dividends or other

17 distributions payable on the Common Stock solely in the form of additional shares of Common Stock or (ii) repurchases of shares of capital stock (at the original purchase price therefor) from officers, employees, directors or consultants of the Corporation which are subject to restrictive stock purchase, right of first refusal or other agreements under which the Corporation has the option to repurchase such shares upon the occurrence of certain events, including termination of employment; or (7) Increase the number of Reserved Employee Shares without the affirmative vote or written consent of at least two of the directors elected solely by the holders of Series A Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock. 5. Conversion. The holders of shares of Series A Convertible Preferred Stock shall have the following conversion rights: 5A. Right to Convert. Subject to the terms and conditions of this paragraph 5, the holder of any share or shares of Series A Convertible Preferred Stock shall have the right, at its option at any time, to convert any such shares of Series A Convertible Preferred Stock (except that upon any Liquidation Event the right of conversion shall terminate at the close of business on the business day fixed for payment of the amounts distributable on the Series A Convertible Preferred Stock) into such number of fully paid and nonassessable shares of Common Stock as is obtained by (i) multiplying the number of shares of Series A Convertible Preferred Stock so to be converted by $7.60 and (ii) dividing the result by the conversion price of $7.60 per share or in case an adjustment of such price has taken place pursuant to the further provisions of this paragraph 5, then by the conversion price as last adjusted and in effect at the date any share or shares of Preferred Stock are surrendered for conversion (such price, or such price as last adjusted, being referred to as the "Series A Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series A Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series A Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued. 5B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 5A and surrender of the certificate or

18 certificates for the share or shares of Series A Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series A Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series A Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the rights of the holder of such share or shares of Series A Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 5C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series A Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon any conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall: (i) if cash is legally available, pay in cash an amount equal to all dividends accrued and unpaid on the shares of Series A Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 5B, or (ii) if cash is not legally available, provide to such holder a certificate representing a number of shares of Common Stock equal to the quotient of all dividends accrued and unpaid on the shares of Series A Convertible Preferred Stock so surrendered divided by the applicable Series A Conversion Price. In case the number of shares of Series A Convertible Preferred Stock represented by the certificate or certificates surrendered pursuant to paragraph 5A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series A Convertible Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 5C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series A Convertible Preferred Stock for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of Shares of Series A Convertible Preferred Stock surrendered by any one holder. 5D. Adjustment of Series A Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 5E and 5F, if and whenever the Corporation shall

19 issue or sell, or is, in accordance with subparagraphs 5D(1) through 5D(8), deemed to have issued or sold, any shares of Common Stock for a consideration per share less than the Series A Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 5F), then, forthwith upon such issue or sale, the Series A Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series A Convertible Preferred Stock) multiplied by the then existing Series A Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale (assuming the conversion of the outstanding shares of Series A Convertible Preferred Stock). For purposes of this paragraph 5D, the following subparagraphs 5D(1) to 5D(8) shall also be applicable: 5D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series A Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter

20 shall be deemed to be outstanding. Except as otherwise provided in subparagraph 5D(3), no adjustment of the Series A Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 5D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series A Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 5D(3), no adjustment of the Series A Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Series A Conversion Price have been or are to be made pursuant to other provisions of this paragraph 5D, no further adjustment of the Series A Conversion Price shall be made by reason of such issue or sale. 5D(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 5D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 5D(1) or 5D(2), or the rate at which Convertible Securities referred to in subparagraph 5D(1) or 5D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series A Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series A Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding

21 provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series A Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series A Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 5D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 5F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. 5D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 5D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common

22 Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 5D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation, and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 5D. 5D(8) Taxed Shares. The initial 650,000 Option Shares (as defined in paragraph 8 herein and including 165,400 shares issued prior to the closing of the initial issuance of the Series A Convertible Preferred Stock) subject to the Plan (as defined in paragraph 8 herein) shall be deemed to be "Taxed Shares". In case at any time the Corporation shall grant an award of any of the Taxed Shares or grant an option to purchase any of the Taxed Shares (including options to purchase an aggregate of 71,500 Taxed Shares granted prior to the date of the initial issuance of Series A Convertible Preferred Stock), the Corporation shall not be required to make any adjustment of the Series A Conversion Price; provided, however, to the extent (i) the right of the Corporation to repurchase shares (at the purchase price paid by the award recipient) subject to an award of Taxed Shares terminates or does not exist and/or (ii) the Corporation issues any shares of its Common Stock upon exercise of an option to purchase Taxed Shares, then such Taxed Shares shall be deemed to be "Issued Taxed Shares," and the Corporation shall adjust the Series A Conversion Price as provided in paragraph 5D hereof and, that for purposes of such adjustment the Corporation shall be deemed to have received no consideration for the Issued Taxed Shares. Notwithstanding the foregoing, if the Company shall repurchase any of the Founders' Shares (as defined in paragraph 8 herein), any such Founders' Shares repurchased by the Company shall reduce the number (on a one-for-one basis) of any Taxed Shares (to the extent that such Taxed Shares have not become Issued Taxed Shares), such that there shall be no adjustment to the Series A Conversion Price upon issuance of the Option Shares previously designated as Taxed Shares. It is the intent of this 5D(8) that notwithstanding any increase in the number of Option Shares permitted by paragraph 8(c), no more than an aggregate of 650,000 Option Shares (appropriately adjusted to reflect an event described in paragraph 5F hereof) be deemed to be Taxed Shares; and all calculations and determinations made pursuant to this 5D(8) shall be made in good faith by the Corporation's Board of Directors after consultation with the Corporation's counsel. 5E. Certain Issues of Common Stock Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series A Conversion Price in the case of the issuance of (i) shares of Common Stock issuable

23 upon conversion of the Series A Convertible Preferred Stock, (ii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock and (iii) Reserved Employee Shares (as defined in paragraph 8 herein) (other than Taxed Shares). 5F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series A Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series A Conversion Price in effect immediately prior to such combination shall be proportionately increased. 5G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series A Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series A Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series A Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 5H. Adjustment of Series A Conversion Price Upon Incurrence of Loss. (1) If and whenever the Purchasers (as defined in the Purchase Agreement) shall be entitled to indemnification pursuant to Section 7.13 of the Purchase Agreement and to the extent the amount of Losses (as defined in the Purchase Agreement) for which indemnification is provided therein is not paid in cash, the Series A Conversion Price shall be adjusted such that the number of shares of Common Stock issuable upon the conversion of

24 one share of Series A Convertible Preferred Stock shall be equal to the sum of (A) the number of shares of Common Stock issuable upon conversion of one share of Series A Convertible Preferred Stock immediately prior to the application of this Section 5H and (B) the Additional Loss Shares. For purposes of this Section 5H, "Additional Loss Shares" shall mean such number of shares of Common Stock as is determined by dividing the Loss Amount (as determined in accordance with Section 7.13(c) of the Purchase Agreement) by the product of (x) the total number of shares of Series A Convertible Preferred Stock then outstanding times (y) the Current Series A Value (as determined in accordance with Section 7.13(c) of the Purchase Agreement). (2) In addition to any other notice required herein, the Corporation shall provide each Purchaser with notice of any Loss promptly upon becoming aware of such Loss, which notice shall specify the amount of such Loss and specify in reasonable detail each individual item of Loss included in the amount so stated. 5I. Notice of Adjustment. Upon any adjustment of the Series A Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series A Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 5J. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all its assets to, another entity or entities; or (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation;

25 then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 5K. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series A Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series A Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series A Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed. 5L. No Reissuance of Series A Convertible Preferred Stock. Shares of Series A Convertible Preferred Stock which are converted into shares of Common Stock as provided herein shall not be reissued. 5M. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series A Convertible Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof, provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the

26 issuance and delivery of any certificate in a name other than that of the holder of the Series A Convertible Preferred Stock which is being converted. 5N. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Preferred Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 5O. Definition of Common Stock. As used in this paragraph 5, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum or percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series A Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 5G. 5P. Mandatory Conversion. All outstanding shares of Series A Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering") provided (i) the aggregate net proceeds from such offering to the Corporation shall be at least $20,000,000; (ii) the price paid by the public for such shares shall be at least $22.80 (appropriately adjusted to reflect the occurrence of any event described in paragraph 5F) and (iii) the offering is a firm commitment underwritten public offering, then effective upon the closing of the sale of such shares by the Corporation pursuant to such public offering, all outstanding shares of Preferred Stock shall automatically convert to shares of Common Stock. 6. Redemption. The shares of Preferred Stock shall be redeemed as follows: 6A. Optional Redemption. The Corporation shall not have the right to call or redeem at any time all or any shares of Series A Convertible Preferred Stock. With the approval of the holders of 66% of the then outstanding shares of Series A Convertible Preferred Stock, one or more holders of shares of Series A Convertible Preferred Stock may,

27 by giving notice (the "Notice") to the Corporation at any time after November 23, 2003 require the Corporation to redeem all of the outstanding Series A Convertible Preferred Stock in two equal installments, with one-half of the shares of Series A Convertible Preferred Stock redeemed on the First Redemption Date (as defined below), and the remainder redeemed on the first anniversary of the First Redemption Date (the "Second Redemption Date"). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series A Convertible Preferred Stock. After receipt of the Notice, the Corporation shall fix the first date for redemption (the "First Redemption Date"), provided that such First Redemption Date shall occur within sixty (60) days after receipt of the Notice. All holders of Series A Convertible Preferred Stock shall deliver to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series A Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series A Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the First Redemption Date. The First Redemption Date and the Second Redemption Date are collectively referred to as the "Redemption Dates". 6B. Redemption Price and Payment. The Series A Convertible Preferred Stock to be redeemed on the Redemption Dates shall be redeemed by paying for each share in cash an amount equal to $7.60 per share, plus an amount equal to all dividends accrued and unpaid on each such share, such amount being referred to as the "Series A Redemption Price." Such payment shall be made in full on each of the Redemption Dates to the holders entitled thereto. 6C. Redemption Mechanics. At least 15 but not more than 35 days prior to each Redemption Date, written notice (the "Redemption Notice") shall be given by the Corporation by mail, postage prepaid, or by facsimile transmission to non-U.S. residents, to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series A Convertible Preferred Stock notifying such holder of the redemption and specifying the Series A Redemption Price, the Redemption Date and the place where said Series A Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at his address as shown by the records of the Corporation. From and after the close of business on the Redemption Date, unless there shall have been a default in the payment of the Series A Redemption Price, all rights of holders of shares of Series A Convertible Preferred Stock (except the right to receive the Series A Redemption Price) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Series A Convertible Preferred Stock on any Redemption Date are insufficient to redeem the total number of outstanding shares of Series A Convertible Preferred Stock to be

28 redeemed on such Redemption Date, the holders of shares of Series A Convertible Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the full number of shares owned by them if all such outstanding shares were redeemed in full. The shares of Series A Convertible Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein; provided, however, that such unredeemed shares shall be entitled to receive interest accruing daily with respect to the applicable Series A Redemption Price at the rate of 15% per annum, payable quarterly in arrears. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series A Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 6D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series A Convertible Preferred Stock redeemed pursuant to this paragraph 6 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series A Convertible Preferred Stock. 7. Amendments. Except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by these terms of the Series A Convertible Preferred Stock by law or by the Certificate of Incorporation, no provision of these terms of the Series A Convertible Preferred Stock may be amended, modified or waived without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock. 8. Definitions. As used herein, the following terms shall have the following meanings: (a) The term "Purchase Agreement" shall mean the Series A Convertible Preferred Stock Purchase Agreement dated as of November 23, 1998 between the Corporation and the Purchasers listed in Exhibit 1.01 thereto as in effect on November 23, 1998. (b) The term the "Plan" shall mean the Corporation's 1998 Stock Incentive Plan. (c) The term "Reserved Employee Shares" shall mean shares of Common Stock reserved by the Corporation pursuant to the Plan from time to time for (i) the sale of shares of Common Stock to employees, consultants or non-employee directors (other than representatives of the holders of Preferred Stock) of the Corporation or (ii) the exercise of options to purchase Common Stock granted to employees, consultants or non-employee directors (other than

29 representatives of the holders of Preferred Stock) of the Corporation, not to exceed in the aggregate 650,000 shares of Common Stock for both clauses (i) and (ii) , with such number including 236,900 shares issued or subject to options granted prior to the date of the initial issuance of the Series A Convertible Preferred Stock (the "Option Shares") (appropriately adjusted to reflect an event described in paragraph 5F hereof), provided that, such number of such shares subject to the Plan shall be increased by up to 839,914 additional shares of Common Stock (appropriately adjusted to reflect an event described in paragraph 5F hereof) (collectively, the "Founders' Shares") upon the repurchase of such Founders' Shares by the Company from the Founders pursuant to contractual rights held by the Company. The foregoing number of Reserved Employee Shares may be increased by the affirmative vote or written consent of the directors elected solely by the holders of Series A Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 60% of the then outstanding shares of Series A Convertible Preferred Stock. (c) The term "Subsidiary" or "Subsidiaries" shall mean any corporation, partnership, trust or other entity of which the Corporation and/or any of its other subsidiaries directly or indirectly owns at the time a majority of the outstanding shares of every class of equity security of such corporation, partnership, trust or other entity.

General. Except as may be otherwise provided in the terms of the Series B Convertible Preferred Stock, in the Certificate of Incorporation (the "Certificate of Incorporation") of Akamai Technologies, Inc. (the "Corporation") or by law, the Series B Convertible Preferred Stock shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each share of Series B Convertible Preferred Stock shall entitle the holder thereof to such number of votes per share on each such action as shall equal the number of shares of Common Stock (including fractions of a share) into which each share of Series B Convertible Preferred Stock is then convertible. 1B. Board Size. Subject to the provisions of paragraph 1C below, the Corporation shall not, without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series B Convertible Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, increase the maximum number of directors constituting the Board of Directors to a number in excess of nine (9). 1C. Board Seats. For so long as at least 50% of the shares of Series B Convertible Preferred Stock issued pursuant to the Purchase Agreement (as defined in paragraph 9 herein) remains outstanding, the holders of the Series B Convertible Preferred Stock, voting as a separate series, shall be entitled to elect one (1) director of the Corporation. At any meeting (or in a written consent in lieu thereof) held for the purpose of electing directors, the presence in person or by proxy (or the written consent) of the holders of at least a majority in interest of the then outstanding shares of Series B Convertible Preferred Stock shall constitute a quorum of the Series B Convertible Preferred Stock for the election of directors to be elected solely by the holders of the Series B Convertible Preferred Stock voting as a separate series. A vacancy in any directorship elected by the holders of the Series B Convertible Preferred Stock will be filled only by the affirmative vote or written consent of the holders of at least 60% of the then outstanding shares of Series B Convertible Preferred Stock. The directors to be elected by the holders of the Series B Convertible Preferred Stock, voting separately as one class, pursuant to this paragraph 1C, shall serve for terms extending from the date of their election and qualification until the time of the next succeeding annual meeting of stockholders and until their successors have been elected and qualified. 2. Ranking. The Series B Convertible Preferred Stock shall rank, with respect to dividend distributions and distributions upon a Liquidation Event (as defined in paragraph 4A herein), senior to all classes of common stock of the Company and to each other class of capital stock or series of preferred stock (including the Series A Convertible Preferred Stock of the

34 Corporation) established before the Preferred Stock Issue Date, by the Board of Directors, pari passu with the Series C Convertible Preferred Stock of the Corporation, and senior or pari passu to any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date by the Board of Directors. All classes of common stock of the Company, the Series A Convertible, Preferred Stock and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date to which the Series B Convertible Preferred Stock is senior, are collectively referred to herein as "Junior Securities". The Series C Convertible Preferred Stock of the Corporation and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date which ranks pari passu with the Series B Convertible Preferred Stock, are collectively referred to herein as "Pari Passu Securities". 3. Dividends. 3A. The holders of shares of the Series B Convertible Preferred Stock shall be entitled to receive, when, as and if dividends are declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative preferential dividends at the annual rate of 8% on the Series B Liquidation Preference Payments (as defined in paragraph 4A herein); provided, however, that any such dividends shall be declared and paid only in the event of (i) a Liquidation Event pursuant to paragraph 4A hereof or (ii) a Redemption pursuant to paragraph 7B hereof. Holders of shares of Series B Convertible Preferred Stock shall be entitled to receive the dividends provided for herein in preference to and in priority over any dividends upon any of the Junior Securities. 3B. Dividends on the Series B Convertible Preferred Stock shall accrue on a daily basis from, the Preferred Stock Issue Date and, to the extent they are not paid, shall accumulate on an annual basis on each December 31, whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of such dividends and whether or not dividends are declared. 4. Liquidation, Dissolution and Winding-Up. 4A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series B Convertible Preferred Stock shall be paid an amount equal to $15.066 per share plus, in the case of each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any Pari Passu Securities, and before any payment shall be made to the holders of any Junior Securities, such amount payable with respect to one share of Series B Convertible Preferred Stock being sometimes referred to as the "Series B Liquidation Preference Payment" and with respect to all shares of Series B Convertible Preferred Stock being sometimes referred to as the "Series B Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series B Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series B Convertible Preferred Stock shall be distributed to such holders of the Series B Convertible Preferred Stock pro rata, so that each

35 holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 4B. Upon any Liquidation Event, immediately after the holders of Series B Convertible Preferred Stock and holders of any Pari Passu Securities have been paid in full pursuant to paragraph 4A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Junior Securities. Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made. shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents not less than 20 days prior to the payment date stated therein, to the holders of record of Series B Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. The (x) consolidation or merger of the Corporation into or with any other entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate thereof (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving Corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction), (y) sale or transfer by the Corporation of all or substantially all of its assets, or (z) sale or transfer by the Corporation's stockholders of capital stock representing a majority of the outstanding capital stock of the Corporation shall be deemed to be a Liquidation Event within the meaning of the provisions of this paragraph 4 (subject to the provisions of this paragraph 4 and not the provisions of paragraph 6G hereof unless paragraph 6G is elected in the following proviso); provided, however, that if the holders of at least 60% of the then outstanding shares of Series B Convertible Preferred Stock shall elect the benefits of the provisions of paragraph 6G in lieu of receiving payment in a Liquidation Event pursuant to this paragraph 4, then all holders of shares of Series B Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 6G in lieu of receiving payment pursuant to this paragraph 4. Whenever the distribution provided for in this paragraph 4 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 5. Restrictions. At any time when at least 50% of the shares of Series B Convertible Preferred Stock issued pursuant to the Purchase Agreement remain outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or the Certificate of Incorporation, without the written consent of the holders of at least 60% of the then outstanding shares of Series B Convertible Preferred Stock given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, the Corporation will not: (1) Consent to any Liquidation Event or merge or consolidate with or into, or permit any Subsidiary to merge or consolidate with or into, any other corporation, corporations, entity or entities (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving corporation and the holders of the Corporation's voting stock

36 outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger pursuant to which the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million); (2) Sell, abandon, transfer, lease or otherwise dispose of all or substantially all of its properties or assets (unless the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million); (3) Amend, alter or repeal any provision of its Certificate of Incorporation or By-laws in a manner adverse to holders of the Series B Convertible Preferred Stock; (4) Create or authorize the creation of or issue any additional class or series of shares of stock (other than the Series C Convertible Preferred Stock of the Corporation) unless the same ranks junior to or on parity with the Series B Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or increase the authorized amount of Series B Convertible Preferred Stock or increase the authorized amount of any additional class or series of shares of stock unless the same ranks junior to or on parity with the Series B Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or create or authorize any obligation or security convertible into shares of Series B Convertible Preferred Stock or into shares of any other class or series of stock unless the same ranks junior to or on parity with the Series B Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, whether any such creation, authorization or increase shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; (5) In any manner amend, alter or change the designations or the powers, preferences or rights, privileges or the restrictions of the Series B Convertible Preferred Stock, provided, however, that the authorization or creation of any shares of capital stock on parity with the Series B Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event shall not require approval of holders of Series B Convertible Preferred Stock; (6) Purchase or redeem, or set aside any sums for the purchase or redemption of, or pay any dividend or make any distribution on, any Junior Securities, except for (i) dividends or other distributions payable on the Common Stock solely in the form of additional shares of Common Stock or (ii) repurchases of shares of capital stock (at the original purchase price therefor) from officers, employees, directors or consultants of the Corporation which are subject to restrictive stock purchase, right of first refusal or other agreements under which the Corporation has the option to repurchase such shares upon the occurrence of certain events, including termination of employment; or (7) Increase the number of Reserved Employee Shares without the affirmative vote or written consent of a majority of the directors designated solely by the holders of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis.

37 6. Conversion. The holders of shares of Series B Convertible Preferred Stock shall have the following conversion rights: 6A. Right to Convert. Subject to the terms and conditions of this paragraph 6, the holder of any share or shares of Series B Convertible Preferred Stock shall have the right, at its option at any time, to convert any such shares of Series B Convertible Preferred Stock (except that upon any Liquidation Event the right of conversion shall terminate at the close of business on the business day fixed for payment of the amounts distributable on the Series B Convertible Preferred Stock) into such number of fully paid and nonassessable shares of Common Stock as is obtained by (i) multiplying the number of shares of Series B Convertible Preferred Stock so to be converted by $15.066 and (ii) dividing the result by the conversion price of $15.066 per share or in case an adjustment of such price has taken place pursuant to the further provisions of this paragraph 6, then by the conversion price as list adjusted and in effect at the date any share or shares of Series B Convertible Preferred Stock are surrendered for conversion (such price, or such price as last adjusted, being referred to as the "Series B Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series B Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series B Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued. 6B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 6A and surrender of the certificate or certificates for the share or shares of Series B Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series B Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series B Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the right of the holder of such share or shares of Series B Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 6C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series B Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon any conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall pay in cash an amount equal to all dividends declared and unpaid (if any) on the shares of Series B Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 6B. In case the number of shares of Series B Convertible Preferred Stock represented by the certificate or certificates

38 surrendered pursuant to paragraph 6A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series B Convertible Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 6C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series B Convertible Preferred Stock for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of shares of Series B Convertible Preferred Stock surrendered by any one holder. 6D. Adjustment of Series B Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 6E and 6F, if and whenever the Corporation shall issue or sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to have issued or sold, any shares of Common Stock for a consideration per share less than the Series B Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 6F), then, forthwith upon such issue or sale, the Series B Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series B Convertible Preferred Stock) multiplied by the then existing Series B Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale (assuming the conversion of the outstanding shares of Series B Convertible Preferred Stock). For purposes of this paragraph 6D, the following subparagraphs 6D(1) to 6D(7) shall also be applicable: 6D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if it any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of

39 all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series B Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding. Except as otherwise provided in subparagraph 6D(3), no adjustment of the Series B Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 6D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series B Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 6D(3), no adjustment of the Series B Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Series B Conversion Price have been or are to be made pursuant to other provisions of this paragraph 6D, no further adjustment of the Series B Conversion Price shall be made by reason of such issue or sale. 6D(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 6D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series B Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series B Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case

40 may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series B Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series B Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 6D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 6F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. 6D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 6D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 6D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation (or any Subsidiary), and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 6D.

41 6E. Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series B Conversion Price in the case of the issuance of (i) shares of Series C Convertible Preferred Stock pursuant to the Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock or Series C Convertible Preferred Stock, (iii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock, Series B Convertible Preferred Stock or Series C Convertible Preferred Stock, (iv) Reserved Employee Shares (as defined in paragraph 9 herein) or (v) warrant shares issued as contemplated by the Purchase Agreement or shares of Common Stock issuable upon conversion of such warrant shares. 6F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series B Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series B Conversion Price in effect immediately prior to such combination shall be proportionately increased. 6G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series B Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series B Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series B Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 6H. Notice of Adjustment. Upon any adjustment of the Series B Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Series B Convertible Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series B Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based.

42 6I. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all of its assets to, another entity or entities; or (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to "exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 6J. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series B Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series B Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series B Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed.

43 6K. No Reissuance of Series B Convertible Preferred Stock. Shares of Series B Convertible Preferred Stock which are converted into shares of Common Stock as provided herein shall not be reissued. 6L. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series B Convertible Preferred Stock shall be made without charge to the holder thereof for any issuance tax in respect thereof; provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder of the Series B Convertible Preferred Stock which is being converted. 6M. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Series B Convertible Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Series B Convertible Preferred Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 6N. Definition of Common Stock. As used in this paragraph 6, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Series B Convertible Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum or percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series B Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 6G. 6O. Mandatory Conversion. All outstanding shares of Series B Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering"), provided (i) the aggregate gross proceeds from such offering to the Corporation shall be at least $20,000,000; (ii) the price paid by the public for such shares shall be at least (x) 2.0 times the then Series B Conversion Price if the Public Offering occurs prior to the 18 month anniversary of the Preferred Stock Issue Date or (y) 3.0 times the then Series B Conversion Price if the Public Offering occurs on or after the 18 month anniversary of the Preferred Stock Issue Date, and (iii) the offering is a firm commitment underwritten Public Offering, and such automatic conversion shall be effective upon the closing of the sale of such shares by the Corporation pursuant to such Public Offering.

44 7. Redemption. The shares of Series B Convertible Preferred Stock shall be redeemed as follows: 7A. Optional Redemption. The Corporation shall not have the right to call or redeem at any time all or any shares of Series B Convertible Preferred Stock. With the approval of the holders of 66% of the then outstanding shares of Series B Convertible Preferred Stock, one or more holders of shares of Series B Convertible Preferred Stock may, by giving notice (the "Notice") to the Corporation, require the Corporation to redeem any or all of the outstanding Series B Convertible Preferred Stock on the Redemption Date (as defined below). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series B Convertible Preferred Stock. After receipt of the Notice, the Corporation shall fix the first date for redemption, which shall be the date specified in the Notice, being any date on or after the earlier of (i) the fifth (5th) anniversary of the Preferred Stock Issue Date and (ii) the date which is the day before the Corporation is due to redeem any outstanding Junior Securities (the "Redemption Date"). All holders of Series B Convertible Preferred Stock shall deliver to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series B Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series B Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the Redemption Date. 7B. Redemption Price and Payment. The Series B Convertible Preferred Stock to be redeemed on the Redemption Date shall be redeemed by paying for each share in cash an amount equal to the Series B Redemption Price (as defined below). For purposes of this paragraph 7B, the "Series B Redemption Price" shall mean $15.066 per share, plus an amount equal to all dividends accrued and unpaid on each such share; provided, however, that if the Redemption Date is after the fifth (5th) anniversary of the Preferred Stock Issue Date, then the "Series B Redemption Price" shall mean the greater of (i) $15.066 per share, plus an amount equal to all dividends accrued and unpaid on each such share and (ii) the Fair Market Value (as defined below) of the Common Stock underlying the Series B Convertible Preferred Stock. Such payment shall be made in full on the Redemption Date to the holders entitled thereto. For purposes of this paragraph 7B, "Fair Market Value" of the Common Stock shall mean the average of the fair market valuations of the Common Stock performed by two investment banks (the "Initial Appraisers"), one of which shall be retained by the Corporation and one of which shall be retained by the holders of a majority in interest of the Series B Convertible Preferred Stock. Subject to the following sentence, such determination by the Initial Appraisers of Fair Market Value shall be final and binding on the parties. If the higher of the two valuations of the Initial Appraisers is equal to or greater than 110% of the lower valuation, the Corporation and holders of a majority in interest of the Series B Convertible Preferred Stock shall select a third investment bank (the "Final Appraiser"), which shall be mutually agreeable to the Corporation and the holders of a majority in interest of the Series B Convertible Preferred Stock. The fair market value of the Common Stock as determined by the Final Appraiser shall be final and binding on the parties. The fees and expenses of the Initial Appraisers shall be paid for by the party selecting such Initial Appraiser and the fees and expenses of the Final Appraiser shall be shared by the Corporation and the holders of the Series B Convertible Preferred Stock.

45 7C. Redemption Mechanics. At least 15 but not more than 35 days prior to the Redemption Date, written notice (the "Redemption Notice") shall be given by the Corporation by mail, postage prepaid, or by facsimile transmission to non-U.S. residents, to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series B Convertible Preferred Stock notifying such holder of the redemption and specifying the Series B Redemption Price, the Redemption Date and the place where said Series B Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at his address as shown by the records of the Corporation. From and after the close of business on the Redemption Date unless there shall have been a default in the payment of the Series B Redemption Price, all rights of holders of shares of Series B Convertible Preferred Stock (except the right to receive the Series B Redemption Price) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Series B Convertible Preferred Stock on the Redemption Date are insufficient to redeem the total number of outstanding shares of Series B Convertible Preferred Stock to be redeemed on such Redemption Date, the holders of shares of Series B Convertible Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the full number of shares owned by them if all such outstanding shares were redeemed in full. The shares of Series B Convertible Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein; provided, however, that such unredeemed shares shall be entitled to receive interest accruing daily with respect to the applicable Series B Redemption Price at the rate of 15% per annum, payable quarterly in arrears. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series B Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 7D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series B Convertible Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series B Convertible Preferred Stock. 8. Amendments. Except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by these terms of the Series B Convertible Preferred Stock, by law or by the Certificate of Incorporation, no provision of these terms of the Series B Convertible Preferred Stock may be amended, modified or waived without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series B Convertible Preferred Stock. 9. Definitions. As used herein, the following terms shall have the following meanings: (1) The term "Founders" shall mean F. Thomson Leighton, Daniel Lewin, Jonathan Seelig, Randall Kaplan, Gilbert Friesen and David Karger.

(5) The term "Reserved Employee Shares" shall mean shares of Common Stock reserved by the Corporation pursuant to the Plan from time to time for (i) the sale of shares of Common Stock to employees, consultants or non-employee directors (other than representatives of the holders of Preferred Stock) of the Corporation or (ii) the exercise of options to purchase Common Stock granted to employees, consultants or non-employee directors (other than representatives of the holders of Preferred Stock) of the Corporation, not to exceed in the aggregate 3,450,000 shares of Common Stock for both clauses (i) and (ii), with such number including 710,700 shares issued or subject to options granted prior to the date of the initial issuance of the Series A Convertible Preferred Stock (the "Option Shares") (approximately adjusted to reflect an event described in paragraph 6F hereof); provided that, such number of such shares subject to the Plan shall be increased by up to 2,519,742 additional shares of Common Stock (appropriately adjusted to reflect an event described in paragraph 6F hereof) (collectively, the "Founders' Shares") upon the repurchase of such Founders' Shares by the Corporation from the Founders pursuant to contractual rights hold by the Corporation.

49 SCHEDULE 1 AKAMAI TECHNOLOGIES, INC. DESIGNATION OF SERIES C CONVERTIBLE PREFERRED STOCK The series of Preferred Stock designated and known as "Series C Convertible Preferred Stock" shall consist of 145,195 shares. 1. Voting. Except as may be otherwise provided in these terms of the Series C Convertible Preferred Stock, in the Certificate of Incorporation (the "Certificate of Incorporation") of Akamai Technologies, Inc. (the "Corporation") or by law, the Series C Convertible Preferred Stock shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each share of Series C Convertible Preferred Stock shall entitle the holder thereof to such number of votes per share on each such action as shall equal the number of shares of Common Stock (including fractions of a share) into which each share of Series C Convertible Preferred Stock is then convertible. 2. Ranking. The Series C Convertible Preferred Stock shall rank, with respect to dividend distributions and distributions upon a Liquidation Event (as defined in paragraph 4A herein), senior to all classes of common stock of the Company and to each other class of capital stock or series of preferred stock (including the Series A Convertible Preferred Stock of the Corporation) established before the Series B Preferred Stock Issue Date, by the Board of Directors, pari passu with the Series B Convertible Preferred Stock of the Corporation, and senior or pari passu to any other class of capital stock or series of preferred stock established after the Series B Preferred Stock Issue Date by the Board of Directors. All classes of common stock of the Company, the Series A Convertible Preferred Stock and any other class of capital stock or series of preferred stock established after the Series B Preferred Stock Issue Date to which the Series C Convertible Preferred Stock is senior, are collectively referred to herein as "Junior Securities". The Series B Convertible Preferred Stock of the Corporation and any other class of capital stock or series of preferred stock established after the Series B Preferred Stock Issue Date which ranks pari passu with the Series C Convertible Preferred Stock, are collectively referred to herein as "Pari Passu Securities". 3. Dividends. 3A. The holders of shares of the Series C Convertible Preferred Stock shall be entitled to receive, when, as and if dividends are declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative preferential dividends at the annual rate of 8% on the Series C Liquidation Preference Payments (as defined in paragraph 4A herein); provided, however, that any such dividends shall be declared and paid only in the event of (i) a Liquidation Event pursuant to paragraph 4A hereof or (ii) a Redemption pursuant to paragraph 7B hereof. Holders of shares of Series C Convertible Preferred Stock shall be entitled to receive the dividends provided for herein in preference to and in priority over any dividends upon any of the Junior Securities. 3B. Dividends on the Series C Convertible Preferred Stock shall accrue on a daily basis from the Series C Preferred Stock Issue Date and, to the extent they are not paid, shall

50 accumulate on an annual basis on each December 31, whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of such dividends and whether or not dividends are declared. 4. Liquidation, Dissolution and Winding-up. 4A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series C Convertible Preferred Stock shall be paid an amount equal to $34.436 per share plus, in the case of each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any Pari Passu Securities, and before any payment shall be made to the holders of any Junior Securities, such amount payable with respect to one share of Series C Convertible Preferred Stock being sometimes referred to as the "Series C Liquidation Preference Payment" and with respect to all shares of Series C Convertible Preferred Stock being sometimes referred to as the "Series C Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series C Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series C Convertible Preferred Stock shall be distributed to such holders of the Series C Convertible Preferred Stock pro rata, so that each holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 4B. Upon any Liquidation Event, immediately after the holders of Series C Convertible Preferred Stock and holders of any Pari Passu Securities have been paid in full pursuant to paragraph 4A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Junior Securities. Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made, shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents, not less than 20 days prior to the payment date stated therein, to the holders of record of Series C Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. The (x) consolidation or merger of the Corporation into or with any other entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate thereof (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving Corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction), (y) sale or transfer by the Corporation of all or substantially all of its assets, or (z) sale or transfer by the Corporation's stockholders of capital stock representing a majority of the outstanding capital stock of the Corporation shall be deemed to be a Liquidation Event within the meaning of the provisions of this paragraph 4 (subject to the provisions of this paragraph 4 and not the provisions of paragraph 6G hereof, unless paragraph 6G is elected in the following proviso); provided, however, that if the holders of at least 60% of the then outstanding shares of Series C Convertible Preferred Stock shall elect the

51 benefits of the provisions of paragraph 6G in lieu of receiving payment in a Liquidation Event pursuant to this paragraph 4, then all holders of shares of Series C Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 6G in lieu of receiving payment pursuant to this paragraph 4. Whenever the distribution provided for in this paragraph 4 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 5. Restrictions. At any time when at least 50% of the shares of Series C Convertible Preferred Stock issued pursuant to the Purchase Agreement remain outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or the Certificate of Incorporation, without the written consent of the holders of at least 60% of the then outstanding shares of Series C Convertible Preferred Stock given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, the Corporation will not: (1) Consent to any Liquidation Event or merge or consolidate with or into, or permit any Subsidiary to merge or consolidate with or into, any other corporation, corporations, entity or entities (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger pursuant to which the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million); (2) Sell, abandon, transfer, lease or otherwise dispose of all or substantially all of its properties or assets (unless the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million); (3) Amend, alter or repeal any provision of its Certificate of Incorporation or By-laws in a manner adverse to holders of the Series C Convertible Preferred Stock; (4) Create or authorize the creation of or issue any additional class or series of shares of stock (other than the Series B Convertible Preferred Stock of the Corporation) unless the same ranks junior to or on parity with the Series C Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or increase the authorized amount of Series C Convertible Preferred Stock or increase the authorized amount of any additional class or series of shares of stock unless the same ranks junior to or on parity with the Series C Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or create or authorize any obligation or security convertible into shares of Series C Convertible Preferred Stock or into shares of any other class or series of stock unless the same ranks junior to or on parity with the Series C Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, whether any such creation, authorization or increase shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise;

52 (5) In any manner amend, alter or change the designations or the powers, preferences or rights, privileges or the restrictions of the Series C Convertible Preferred Stock, provided, however, that the authorization or creation of any shares of capital stock on parity with the Series C Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event shall not require approval of holders of Series C Convertible Preferred Stock; (6) Purchase or redeem, or set aside any sums for the purchase or redemption of, or pay any dividend or make any distribution on, any Junior Securities, except for (i) dividends or other distributions payable on the Common Stock solely in the form of additional shares of Common Stock or (ii) repurchases of shares of capital stock (at the original purchase price therefor) from officers, employees, directors or consultants of the Corporation which are subject to restrictive stock purchase, right of first refusal or other agreements under which the Corporation has the option to repurchase such shares upon the occurrence of certain events, including termination of employment; or (7) Increase the number of Reserved Employee Shares without the affirmative vote or written consent of a majority of the directors designated solely by the holders of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis. 6. Conversion. The holders of shares of Series C Convertible Preferred Stock shall have the following conversion rights: 6A. Right to Convert. Subject to the terms and conditions of this paragraph 6, the holder of any share or shares of Series C Convertible Preferred Stock shall have the right, at its option at any time, to convert any such shares of Series C Convertible Preferred Stock (except that upon any Liquidation Event the right of conversion shall terminate at the close of business on the business day fixed for payment of the amounts distributable on the Series C Convertible Preferred Stock) into such number of fully paid and nonassessable shares of Common Stock as is obtained by (i) multiplying the number of shares of Series C Convertible Preferred Stock so to be converted by $34.436 and (ii) dividing the result by the conversion price of $34.436 per share or in case an adjustment of such price has taken place pursuant to the further provisions of this paragraph 6, then by the conversion price as last adjusted and in effect at the date any share or shares of Series C Convertible Preferred Stock are surrendered for conversion (such price, or such price as last adjusted, being referred to as the "Series C Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series C Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series C Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued.

53 6B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 6A and surrender of the certificate or certificates for the share or shares of Series C Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series C Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series C Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the rights of the holder or such share or shares of Series C Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 6C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series C Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon any conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall pay in cash an amount equal to all dividends declared and unpaid (if any) on the shares of Series C Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 6B. In case the number of shares of Series C Convertible Preferred Stock represented by the certificate or certificates surrendered pursuant to paragraph 6A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series C Convertible Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 6C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series C Convertible Preferred Stock for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of shares of Series C Convertible Preferred Stock surrendered by any one holder. 6D. Adjustment of Series C Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 6E and 6F, if and whenever the Corporation shall issue or sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to have issued or sold, any shares of Common Stock for a consideration per share less than the Series C Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 6F), then, forthwith upon such issue or sale, the Series C Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series C Convertible Preferred Stock) multiplied by the then existing Series C Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately

54 after such issue or sale (assuming the conversion of the outstanding shares of Series C Convertible Preferred Stock). For purposes of this paragraph 6D, the following subparagraphs 6D(1) to 6D(7) shall also be applicable: 6D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series C Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding. Except as otherwise provided in subparagraph 6D(3), no adjustment of the Series C Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 6D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series C Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of

55 shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 6D(3), no adjustment of the Series C Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercise or any Options to purchase any such Convertible Securities for which adjustments of the Series C Conversion Price have been or are to be made pursuant to other provisions of this paragraph 6D, no further adjustments of the Series C Conversion Price shall be made by reason of such issue or sale. 6D(3) Change in Option Price of Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 6D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason if provisions designed to protect against dilution), the Series C Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series C Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series C Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series C Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 6D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 6F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. 6D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by

56 the Board of Directors of the Corporation without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 6D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 6D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation (or any Subsidiary), and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 6D. 6E. Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment for the Series C Conversion Price in the case of the issuance of (i) shares of Series B Convertible Preferred Stock pursuant to the Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock or Series C Convertible Preferred Stock, (iii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock, Series B Convertible Preferred Stock or Series C Convertible Preferred Stock, (iv) Reserved Employee Shares (as defined in paragraph 9 herein) or (v) warrant shares issued as contemplated by the Purchase Agreement or shares of Common Stock issuable upon conversion of such warrant shares. 6F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series C Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series C Conversion Price in effect immediately prior to such combination shall be proportionately increased. 6G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change,

57 lawful and adequate provisions shall be made whereby each holder of a share or shares of Series C Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series C Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series C Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 6H. Notice of Adjustment. Upon any adjustment of the Series C Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Series C Convertible Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series C Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 6I. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all of its assets to, another entity or entities; or (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend,

58 distribution or subscription rights, the date on which the holders or Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 6J. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series C Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series C Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series C Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed. 6K. No Reissuance of Series C Convertible Preferred Stock. Shares of Series C Convertible Preferred Stock which are converted into shares of Common Stock as provided herein shall not be reissued. 6L. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series C Convertible Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof; provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder of the Series C Convertible Preferred Stock which is being converted. 6M. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Series C Convertible Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Series C Convertible Preferred Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 6N. Definition of Common Stock. As used in this paragraph 6, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Series C Convertible Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum of percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series C Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or

59 reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 6G. 6O. Mandatory Conversion. All outstanding shares of Series C Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering"), provided (i) the aggregate gross proceeds from such offering to the Corporation shall be at least $20,000,000; (ii) the price paid by the public for such shares shall be at least (x) 2.0 times the then Series B Conversion Price if the Public Offering occurs prior to the 18 month anniversary of the Series B Preferred Stock Issue Date or (y) 3.0 times the then Series B Conversion Price if the Public Offering occurs on or after the 18 month anniversary of the Series B Preferred Stock Issue Date, and (iii) the offering is a firm commitment underwritten Public Offering, and such automatic conversion shall be effective upon the closing of the sale of such shares by the Corporation pursuant to such Public Offering. 7.

With the approval of the holders of 66% of the then outstanding shares of Series C Convertible Preferred Stock, one or more holders of shares of Series C Convertible Preferred Stock may, by giving notice (the "Notice") to the Corporation, require the Corporation to redeem any or all of the outstanding Series C Convertible Preferred Stock on the Redemption Date (as defined below). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series C Convertible Preferred Stock.

All holders of Series C Convertible Preferred Stock shall delivery to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series C Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series C Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the Redemption Date. 7B. Redemption Price and Payment. The Series C Convertible Preferred Stock to be redeemed on the Redemption date shall be redeemed by paying for each share in cash an amount equal to the Series C Redemption Price (as defined below). For purposes of this paragraph 7B the "Series C Redemption Price" shall mean $34.436 per share, plus an amount equal to all dividends accrued and unpaid on each such share; provided, however, that if the Redemption Date is after the fifth (5th) anniversary of the Series B Preferred Stock Issue Date, then the "Series C Redemption Price" shall mean the greater of (i) $34.436 per share, plus an amount equal to all dividends accrued and unpaid on each such share and (ii) the Fair Market Value (as defined below) of the Common Stock underlying the Series C Convertible Preferred Stock. Such payment shall be made in full on the Redemption Date to the holders entitled

60 thereto. For purposes of this paragraph 7B, "Fair Market Value" of the Common stock shall mean the average of the fair market valuations of the Common Stock performed by two investment banks (the "Initial Appraisers"), one of which shall be retained by the Corporation and one of which shall be retained by the holders of a majority in interest of the Series C Convertible Preferred Stock. Subject to the following sentence, such determination by the Initial Appraisers of Fair Market Value shall be final and binding on the parties. If the higher of the two valuations of the Initial Appraisers is equal to or greater than 110% of the lower valuation, the Corporation and holders of a majority in interest of the Series C Convertible Preferred Stock shall select a third investment bank (the "Final Appraiser"), which shall be mutually agreeable to the Corporation and the holders of a majority in interest of the Series C Convertible Preferred Stock. The fair market value of the Common Stock as determined by the Final Appraiser shall be final and binding on the parties. The fees and expenses of the Initial Appraisers shall be paid for by the party selecting such Initial Appraiser and the fees and expenses of the Final Appraiser shall be shared by the Corporation and the holders of the Series C Convertible Preferred Stock. 7C. Redemption Mechanics. At least 15 but not more than 35 days prior to the Redemption Date, written notice (the "Redemption Notice") shall be given by the Corporation by mail, postage prepaid, or by facsimile transmission to non-U.S. residents, to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series C Convertible Preferred Stock notifying such holder of the redemption and specifying the Series C Redemption Price, the Redemption Date and the place where said Series C Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at his address as shown by the records of the Corporation. From and after the close of business on the Redemption Date, unless there shall have been a default in the payment of the Series C Redemption Price, all rights of holders of shares of Series C Convertible Preferred Stock (except the right to receive the Series C Redemption Price) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Series C Convertible Preferred Stock on the Redemption Date are insufficient to redeem the total number of outstanding shares of Series C Convertible Preferred Stock to be redeemed on such Redemption Date, the holders of shares of Series C Convertible Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the full number of shares owned by them if all such outstanding shares were redeemed in full. The shares of Series C Convertible Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein; provided, however, that such unredeemed shares shall be entitled to receive interest accruing daily with respect to the applicable Series C Redemption Price at the rate of 15% per annum, payable quarterly in arrears. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series C Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 7D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series C Convertible Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any

61 circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series C Convertible Preferred Stock. 8. Amendments. Except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by these terms of the Series C Convertible Preferred Stock, by law or by the Certificate of Incorporation, no provision of these terms of the Series C Convertible Preferred Stock may be amended, modified or waived without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series C Convertible Preferred Stock. 9. Definitions. As used herein, the following terms shall have the following meanings: (1) The term "Founders" shall mean F. Thornson Leighton, Daniel Lewin, Jonathan Seelig, Randall Kaplan, Gilbert Friesen and David Karger. (2) The term "Purchase Agreement" shall mean the Series B Convertible Preferred Stock and Series C Convertible Preferred Stock Purchase Agreement dated as of April 16, 1999 between the Corporation, Baker Communications Fund, L.P. and the other purchasers named therein, as in effect on April 16, 1999.

The foregoing numbers of Reserved Employee Shares may be increased by the affirmative vote or written consent of a majority of the directors designated solely by the holders of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis.

66 Schedule I AKAMAI TECHNOLOGIES, INC. DESIGNATION OF SERIES D CONVERTIBLE PREFERRED STOCK The series of Preferred Stock designated and known as "Series D Convertible Preferred Stock" shall consist of 685,194 shares. 1. Voting. Except as may be otherwise provided in these terms of the Series D Convertible Preferred Stock, in the Certificate of Incorporation (the "Certificate of Incorporation") of Akamai Technologies, Inc. (the "Corporation") or by law, the Series D Convertible Preferred Stock shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each share of Series D Convertible Preferred Stock shall entitle the holder thereof to such number of votes per share on each such action as shall equal the number of shares of Common Stock (including fractions of a share) into which each share of Series D Convertible Preferred Stock is then convertible. 2. Ranking. The Series D Convertible Preferred Stock shall rank, with respect to dividend distributions and distributions upon a Liquidation Event (as defined in paragraph 4A herein), senior to all classes of common stock of the Company and to each other class of capital stock or series of preferred stock (including the Series A Convertible Preferred Stock of the Corporation) established before the Series B Preferred Stock Issue Date, by the Board of Directors, pari passu with the Series B Convertible Preferred Stock and the Series C Convertible Preferred Stock of the Corporation, and senior or pari passu to any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date by the Board of Directors. All classes of common stock of the Company, the Series A Convertible Preferred Stock and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date to which the Series D Convertible Preferred Stock is senior, are collectively referred to herein as "Junior Securities". The Series B Convertible Preferred Stock and the Series C Convertible Preferred Stock of the Corporation and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date which ranks pari passu with the Series D Convertible Preferred Stock, are collectively referred to herein as "Pari Passu Securities". 3. Dividends. The holders of shares of the Series D Convertible Preferred Stock shall be entitled to receive, when, as and if dividends are declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative preferential dividends at the annual rate of 8% on the Series D Liquidation Preference Payments (as defined in paragraph 4A herein); provided, however, that any such dividends shall only be paid, whether declared or not, immediately upon the occurrence of (i) a Liquidation Event pursuant to paragraph 4.A hereof or (ii) a Redemption pursuant to paragraph 7B hereof. Holders of shares of Series D Convertible Preferred Stork shall be entitled to receive the dividends provided for herein in preference to and in priority over any dividends upon any of the Junior Securities. Dividends on the Series D Convertible Preferred Stock shall accrue on a daily basis from the Preferred Stock Issue Date and, to the extent they are not paid, shall accumulate on an annual basis on each December 31,

67 whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of such dividends and whether or not dividends are declared. 4. Liquidation, Dissolution and Winding-up. 4A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series D Convertible Preferred Stock shall be paid an amount equal to $18.243 per share plus, in the case of each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any Pari Passu Securities, and before any payment shall be made to the holders of any Junior Securities, such amount payable with respect to one share of Series D Convertible Preferred Stock being sometimes referred to as the "Series D Liquidation Preference Payment" and with respect to all shares of Series D Convertible Preferred Stock being sometimes referred to as the "Series D Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series D Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series D Convertible Preferred Stock and Pari Passu Securities shall be distributed to such holders of the Series D Convertible Preferred Stock and Pari Passu Securities pro rata, so that each holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 4B. Upon any Liquidation Event, immediately after the holders of Series D Convertible Preferred Stock and holders of any Pari Passu Securities have been paid in full pursuant to paragraph 4A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Junior Securities. Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made, shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents, not less than 20 days prior to the payment date stated therein, to the holders of record of Series D Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. The (x) consolidation or merger of the Corporation into or with any other entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate thereof (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving Corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction), (y) sale or transfer by the Corporation of all or substantially all of its assets, or (z) sale or transfer by the Corporation's stockholders of capital stock representing a majority of the outstanding capital stock of the Corporation shall be deemed to be a Liquidation Event within the meaning of the provisions of this paragraph 4 (subject to the provisions of this paragraph 4 and not the provisions of paragraph 6G hereof, unless paragraph 6G is elected in the following proviso); provided, however, that if the holders of at

68 least 60% of the then outstanding shares of Series D Convertible Preferred Stock shall elect the benefits of the provisions of paragraph 6G in lieu of receiving payment in a Liquidation Event pursuant to this paragraph 4, then all holders of shares of Series D Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 6G in lieu of receiving payment pursuant to this paragraph 4 for the particular Organic Change (as defined in Section 6G) causing the rights of Section 6G to be available. The election of the rights under Section 6G for any particular Organic Change shall not constitute an election of the rights available under Section 6G for any other Organic Change, for which the holders of Series D Convertible Preferred Stock shall have a new election under the foregoing proviso. Whenever the distribution provided for in this paragraph 4 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 5. Restrictions. At any time when at least 50% of the shares of Series D Convertible Preferred Stock issued pursuant to the Purchase Agreement remain outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or the Certificate of Incorporation, without the written consent of the holders of at least 60% of the then outstanding shares of Series D Convertible Preferred Stock given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, the Corporation will not: (1) Consent to any Liquidation Event or merge or consolidate with or into, or permit any Subsidiary to merge or consolidate with or into, any other corporation, corporations, entity or entities (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger pursuant to which the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million) without the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series D Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis; (2) Sell, abandon, transfer, lease or otherwise dispose of all or substantially all of its properties or assets (unless the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $400 million) without the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series D Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis; (3) Amend, alter or repeal any provision of its Certificate of Incorporation or By-laws in a manner adverse to holders of the Series D Convertible Preferred Stock;

Conversion. The holders of shares of Series D Convertible Preferred Stock shall have the following conversion rights: 6A. Right to Convert. Subject to the terms and conditions of this paragraph 6, the holder of any share or shares of Series D Convertible Preferred Stock shall have the right, at its option at any time, to convert any such shares of Series D Convertible Preferred Stock (except that upon any Liquidation Event the right of conversion shall terminate at the close of business on the business day fixed for payment of the amounts distributable on the Series D

70 Convertible Preferred Stock) into such number of fully paid and nonassessable shares of Common Stock as is obtained by (i) multiplying the number of shares of Series D Convertible Preferred Stock so to be converted by $18.243 and (ii) dividing the result by the conversion price of $6.081 per share or in case an adjustment of such price has taken place pursuant to the further provisions of this paragraph 6, then by the conversion price as last adjusted and in effect at the date any share or shares of Series D Convertible Preferred Stock are surrendered for conversion (such price, or such price as last adjusted, being referred to as the "Series D Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series D Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series D Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued. 6B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 6A and surrender of the certificate or certificates for the share or shares of Series D Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series D Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series D Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the rights of the holder of such share or shares of Series D Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 6C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series D Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon party conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall pay in cash an amount equal to all dividends declared and unpaid (if any) on the shares of Series D Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 6B. In case the number of shares of Series D Convertible Preferred Stock represented by the certificate or certificates surrendered pursuant to paragraph 6A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series D Convertible Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 6C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series D Convertible Preferred Stock

71 for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of shares of Series D Convertible Preferred Stock surrendered by any one holder. 6D. Adjustment of Series D Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 6E and 6F, if and whenever the Corporation shall issue or sell, or is, in accordance with subparagraphs, 6D(1) through 6D(7), deemed to have issued or sold, any shares of Common Stock for a consideration per share less than the Series D Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 6F), then, forthwith upon such issue or sale, the Series D Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series D Convertible Preferred Stock) multiplied by the then existing Series D Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale (assuming the conversion of the outstanding shares of Series D Convertible Preferred Stock). For purposes of this paragraph 6D, the following subparagraphs 6D(1) to 6D(7) shall also be applicable: 6D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series D Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such

72 Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding. Except as otherwise provided in subparagraph 6D(3), no adjustment of the Series D Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 6D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series D Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 6D(3), no adjustment of the Series D Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Series D Conversion Price have been or are to be made pursuant to other provisions of this paragraph 6D, no further adjustment of the Series D Conversion Price shall be made by reason of such issue or sale. 6D(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 6D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series D Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series D Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series D Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series D Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been

73 in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 6D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 6F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. 6D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 6D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 6D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation (or any Subsidiary), and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 6D. 6E. Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series D Conversion Price if it first obtains the written consent of the holders of at least 60% of the then outstanding shares

74 of Series D Convertible Preferred Stock that no adjustment shall be required. In no event shall the Corporation be required to make any adjustment to the Series D Conversion Price in the case of the issuance of (i) shares of Series C Convertible Preferred Stock pursuant to the Series B Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock or Series D Convertible Preferred Stock, (iii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock or Series D Convertible Preferred Stock, (iv) Reserved Employee Shares (as defined in paragraph 9 herein), (v) warrants issued in connection with senior subordinated notes of the Corporation as contemplated by the Series B Purchase Agreement or shares of Common Stock issuable upon conversion of such warrants, or (vi) Options outstanding as of the Preferred Stock Issue Date. 6F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series D Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series D Conversion Price in effect immediately prior to such combination shall be proportionately increased. 6G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series D Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series D Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and Interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series D Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 6H. Notice of Adjustment. Upon any adjustment of the Series D Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Series D Convertible Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series D Conversion Price resulting

75 from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 6I. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all of its assets to, another entity or entities; or (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of arty such dividend, distribution or subscription rights, the date on which the holders of Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 6J. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series D Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series D Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series D Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of

76 Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed. 6K. No Reissuance of Series D Convertible Preferred Stock. Shares of Series D Convertible Preferred Stock which are converted into shares of Common Stock as provided herein shall not be reissued. 6L. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series D Convertible Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof; provided, that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder of the Series D Convertible Preferred Stock which is being converted. 6M. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Series D Convertible Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Series D Convertible Preferred Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 6N. Definition of Common Stock. As used in this paragraph 6, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Series D Convertible Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum or percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series D Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 6G. 6O. Mandatory Conversion. All outstanding shares of Series D Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering"), provided (i) the aggregate gross proceeds from such offering to the Corporation shall be at least $20,000,000; (ii) the price paid by the public for such shares shall be at least (x) 2.0 times the then Series B Conversion Price if the Public Offering occurs prior to the 18 month anniversary of the Series B Preferred Stock Issue Date or (y) 3.0 times the then Series B Conversion Price if the Public Offering occurs on or after the 18 month anniversary of the Series B Preferred Stock Issue Date, and (iii) the offering is a firm commitment underwritten Public Offering, and such automatic conversion shall be effective upon the closing of the sale of such shares by the Corporation pursuant to such Public Offering.

77 7. Redemption. The shares of Series D Convertible Preferred Stock shall be redeemed as follows: 7A. Operational Redemption. The Corporation shall not have the right to call or redeem at any time all or any shares of Series D Convertible Preferred Stock. With the approval of the holders of 66% of the then outstanding shares of Series D Convertible Preferred Stock, one or more holders of shares of Series D Convertible Preferred Stock may, by giving notice (the "Notice") to the Corporation, require the Corporation to redeem any or all of the outstanding Series D Convertible Preferred Stock on the Redemption Date (as defined below). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series D Convertible Preferred Stock. After receipt of the Notice, the Corporation shall fix the first date for redemption, which shall be the date specified in the Notice, being any date on or after the earlier of (i) the fifth (5th) anniversary of the Series B Preferred Stock Issue Date and (ii) the date which is the day before the Corporation is due to redeem any outstanding Junior Securities (the "Redemption Date"). All holders of Series D Convertible Preferred Stock shall deliver to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series D Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series D Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the Redemption Date. 7B. Redemption Price and Payment. The Series D Convertible Preferred Stock to be redeemed on the Redemption Date shall be redeemed by paying for each share in cash an amount equal to the Series D Redemption Price (as defined below). For purposes of this paragraph 7B, the "Series D Redemption Price" shall mean $18.243 per share, plus an amount equal to all dividends accrued and unpaid on each such share, provided, however, that if the Redemption Date is after the fifth (5th) anniversary of the Series B Preferred Stock Issue Date, then the "Series D Redemption Price" shall mean the greater of (i) $18.243 per share, plus an amount equal to all dividends accrued and unpaid on each such share and (ii) the Fair Market Value (as defined below) of the Common Stock underlying the Series D Convertible Preferred Stock. Such payment shall be made in full on the Redemption Date to the holders entitled thereto. For purposes of this paragraph 7B, "Fair Market Value" of the Common Stock shall mean the average of the fair market valuations of the Common Stock performed by two investment banks (the "Initial Appraisers"), one of which shall be retained by the Corporation and one of which shall be retained by the holders of a majority in interest of the Series D Convertible Preferred Stock. Subject to the following sentence, such determination by the Initial Appraisers of Fair Market Value shall be final and binding on the parties. If the higher of the two valuations of the Initial Appraisers is equal to or greater than 110% of the lower valuation, the Corporation and holders of a majority in interest of the Series D Convertible Preferred Stock shall select a third investment bank (the "Final Appraiser"), which shall be mutually agreeable to the Corporation and the holders of a majority in interest of the Series D Convertible Preferred Stock. The fair market value of the Common Stock as determined by the Final Appraiser shall be final and binding on the parties. The fees and expenses of the Initial Appraisers shall be paid for by the party selecting such Initial Appraiser and the fees and expenses of the final Appraiser shall be shared by the Corporation and the holders of the Series D Convertible Preferred Stock.

78 7C. Redemption Mechanics. At least 15 but not more than 35 days prior to the Redemption Date, written notice (the "Redemption Notice") shall be given by the Corporation by mail, postage prepaid, or by facsimile transmission to non-U.S. residents, to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series D Convertible Preferred Stock notifying such holder of the redemption and specifying the Series D Redemption Price, the Redemption Date and the place where said Series D Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at his address as shown by the records of the Corporation. From and after the close of business on the Redemption Date, unless there shall have been a default in the payment of the Series D Redemption Price, all rights of holders of shares of Series D Convertible Preferred Stock (except the right to receive the Series D Redemption Price) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Series D Convertible Preferred Stock on the Redemption Date are insufficient to redeem the total number of outstanding shares of Series D Convertible Preferred Stock to be redeemed on such Redemption Date, the holders of shares of Series D Convertible Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the full number of shares owned by them if all such outstanding shares were redeemed in full. The shares of Series D Convertible Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein; provided, however, that such unredeemed shares shall be entitled to receive interest accruing daily with respect to the applicable Series D Redemption Price at the rate of 15% per annum, payable quarterly in arrears. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series D Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 7D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series D Convertible Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series D Convertible Preferred Stock. 8. Amendments. Except where the vote or written consent of the holders of a different number of shares of the Corporation is required by these terms of the Series D Convertible Preferred Stock, by law or by the Certificate of Incorporation, no provision of these terms of the Series D Convertible Preferred Stock may be amended, modified or waived without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series D Convertible Preferred Stock.

82 Schedule I AKAMAI TECHNOLOGIES, INC. DESIGNATION OF SERIES E CONVERTIBLE PREFERRED STOCK The series of Preferred Stock designated and known as "Series E Convertible Preferred Stock" shall consist of 1,867,480 shares. 1. Voting. Except as may be otherwise provided in these terms of the Series E Convertible Preferred Stock, in the Certificate of Incorporation (the "Certificate of Incorporation") of Akamai Technologies, Inc. (the "Corporation") or by law, the Series E Convertible Preferred Stock shall vote together with all other classes and series of stock of the Corporation as a single class on all actions to be taken by the stockholders of the Corporation. Each share of Series E Convertible Preferred Stock shall entitle the holder thereof to such number of votes per share on each such action as shall equal the number of shares of Common Stock (including fractions of a share) into which each share of Series E Convertible Preferred Stock is then convertible. 2. Ranking. The Series E Convertible Preferred Stock shall rank, with respect to dividend distributions and distributions upon a Liquidation Event (as defined in paragraph 4A herein), senior to all classes of common stock of the Company and to each other class of capital stock or series of preferred stock (including the Series A Convertible Preferred Stock of the Corporation) established before the Series B Preferred Stock Issue Date, by the Board of Directors, pari passu with the Series B Convertible Preferred Stock, the Series C Convertible Preferred Stock and the Series D Convertible Preferred Stock of the Corporation, and senior or pari passu to any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date by the Board of Directors. All classes of common stock of the Company, the Series A Convertible Preferred Stock and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date to which the Series E Convertible Preferred Stock is senior, are collectively referred to herein as "Junior Securities". The Series B Convertible Preferred Stock, the Series C Convertible Preferred Stock and the Series D Convertible Preferred Stock of the Corporation and any other class of capital stock or series of preferred stock established after the Preferred Stock Issue Date which ranks pari passu with the Series E Convertible Preferred Stock, are collectively referred to herein as "Pari Passu Securities". 3. Dividends. The holders of shares of the Series E Convertible Preferred Stock shall be entitled to receive, when, as and if dividends are declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative preferential dividends at the annual rate of 8% on the Series E Liquidation Preference Payments (as defined in paragraph 4A herein); provided, however, that any such dividends shall only be paid, whether declared or not, immediately upon the occurrence of (i) a Liquidation Event pursuant to paragraph 4A hereof or (ii) a Redemption pursuant to paragraph 7B hereof. Holders of shares of Series E Convertible Preferred Stock shall be entitled to receive the dividends provided for herein in preference to and in priority over any dividends upon any of the Junior Securities. Dividends on the Series E Convertible Preferred Stock shall accrue on a daily basis from the Preferred Stock Issue Date and, to the extent they are not paid, shall accumulate on an annual basis on each December 31,

83 whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of such dividends and whether or not dividends are declared. 4. Liquidation, Dissolution and Winding-up. 4A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series E Convertible Preferred Stock shall be paid an amount equal to $26.239 per share plus, in the case of each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any Pari Passu Securities, and before any payment shall be made to the holders of any Junior Securities, such amount payable with respect to one share of Series E Convertible Preferred Stock being sometimes referred to as the "Series E Liquidation Preference Payment" and with respect to all shares of Series E Convertible Preferred Stock being sometimes referred to as the "Series E Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series E Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series E Convertible Preferred Stock and Pari Passu Securities shall be distributed to such holders of the Series E Convertible Preferred Stock and Pari Passu Securities pro rata, so that each holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 4B. Upon any Liquidation Event, immediately after the holders of Series E Convertible Preferred Stock and holders of any Pari Passu Securities have been paid in full pursuant to paragraph 4A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Junior Securities. Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made, shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents, not less than 20 days prior to the payment date stated therein, to the holders of record of Series E Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation.

84 pursuant to this paragraph 4, then all holders of shares of Series E Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 6G in lieu of receiving payment pursuant to this paragraph 4 for the particular Organic Change (as defined in Section 6G) causing the rights of Section 6G to be available. The election of the rights under Section 6G for any particular Organic Change shall not constitute an election of the rights available under Section 6G for any other Organic Change, for which the holders of Series E Convertible Preferred Stock shall have a new election under the foregoing proviso. Whenever the distribution provided for in this paragraph 4 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 5.

86 price, or such price as last adjusted, being referred to as the "Series E Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series E Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series E Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued. 6B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 6A and surrender of the certificate or certificates for the share or shares of Series E Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series E Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series E Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the rights of the holder of such share or shares of Series E Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 6C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series E Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon any conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall pay in cash an amount equal to all dividends declared and unpaid (if any) on the shares of Series E Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 6B. In case the number of shares of Series E Convertible Preferred Stock represented by the certificate or certificates surrendered pursuant to paragraph 6A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series E Convertible Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 6C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series E Convertible Preferred Stock for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of shares of Series E Convertible Preferred Stock surrendered by any one holder. 6D. Adjustment of Series E Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 6E and 6F, if and whenever the Corporation shall issue or sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to have issued or sold,

87 any shares of Common Stock for a consideration per share less than the Series E Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 6F), then, forthwith upon such issue or sale, the Series E Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series E Convertible Preferred Stock) multiplied by the then existing Series E Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale (assuming the conversion of the outstanding shares of Series E Convertible Preferred Stock). For purposes of this paragraph 6D, the following subparagraphs 6D(1) to 6D(7) shall also be applicable: 6D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series E Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding. Except as otherwise provided in subparagraph 6D(3), no adjustment of the Series E Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 6D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which

88 Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series E Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 6D(3), no adjustment of the Series E Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Series E Conversion Price have been or are to be made pursuant to other provisions of this paragraph 6D, no further adjustment of the Series E Conversion Price shall be made by reason of such issue or sale. 6D(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 6D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series E Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series E Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series E Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series E Conversion Price then in effect hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 6D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 6F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration.

89 6D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 6D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 6D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation (or any Subsidiary), and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 6D. 6E. Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series E Conversion Price if it first obtains the written consent of the holders of at least 60% of the then outstanding shares of Series E Convertible Preferred Stock that no adjustment shall be required. In no event shall the Corporation be required to make any adjustment to the Series E Conversion Price in the case of the issuance of (i) shares of Series C Convertible Preferred Stock pursuant to the Series B Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock or Series E Convertible Preferred Stock, (iii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock or Series E Convertible Preferred Stock, (iv) Reserved Employee Shares (as defined in paragraph 9 herein), (v) warrants issued in connection with senior subordinated notes of the Corporation as contemplated by the Series B Purchase Agreement or shares of Common Stock issuable upon conversion of such warrants, or (vi) Options outstanding as of the Preferred Stock Issue Date.

90 6F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series E Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series E Conversion Price in effect immediately prior to such combination shall be proportionately increased. 6G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series E Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series E Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series E Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 6H. Notice of Adjustment. Upon any adjustment of the Series E Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Series E Convertible Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series E Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 6I. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all of its assets to, another entity or entities; or

91 (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 6J. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series E Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series E Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series E Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed. 6K. No Reissuance of Series E Convertible Preferred Stock. Shares of Series E Convertible Preferred Stock which are converted into shares of Common Stock as provided herein shall not be reissued. 6L. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series E Convertible Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof; provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder of the Series E Convertible Preferred Stock which is being converted. 6M. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Series E Convertible Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Series E Convertible Preferred

92 Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 6N. Definition of Common Stock. As used in this paragraph 6, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Series E Convertible Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum or percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series E Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 6G. 6O. Mandatory Conversion. All outstanding shares of Series E Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering"), provided (i) the aggregate gross proceeds from such offering to the Corporation shall be at least $20,000,000, (ii) the price paid by the public for such shares shall be at least (x) 2.0 times the then Series B Conversion Price if the Public Offering occurs prior to the 18 month anniversary of the Series B Preferred Stock Issue Date or (y) 3.0 times the then Series B Conversion Price if the Public Offering occurs on or after the 18 month anniversary of the Series B Preferred Stock Issue Date and (iii) the offering is a firm commitment underwritten Public Offering, and such automatic conversion shall be effective upon the closing of the sale of such shares by the Corporation pursuant to such Public Offering.

93 7. Redemption. The shares of Series E Convertible Preferred Stock shall be redeemed as follows: 7A. Optional Redemption. The Corporation shall not have the right to call or redeem at any time all or any shares of Series E Convertible Preferred Stock. With the approval of the holders of 66% of the then outstanding shares of Series E Convertible Preferred Stock, one or more holders of shares of Series E Convertible Preferred Stock may, by giving notice (the "Notice") to the Corporation, require the Corporation to redeem any or all of the outstanding Series E Convertible Preferred Stock on the Redemption Date (as defined below). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series E Convertible Preferred Stock. After receipt of the Notice, the Corporation shall fix the first date for redemption, which shall be the date specified in the Notice, being any date on or after the earlier of (i) the fifth (5th) anniversary of the Series B Preferred Stock Issue Date and (ii) the date which is the day before the Corporation is due to redeem any outstanding Junior Securities (the "Redemption Date"). All holders of Series E Convertible Preferred Stock shall deliver to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series E Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series E Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the Redemption Date. 7B. Redemption Price and Payment. The Series E Convertible Preferred Stock to be redeemed on the Redemption Date shall be redeemed by paying for each share in cash an amount equal to the Series E Redemption Price (as defined below). For purposes of this paragraph 7B, the "Series E Redemption Price" shall mean $26.239 per share, plus an amount equal to all dividends accrued and unpaid on each such share; provided, however, that if the Redemption Date is after the fifth (5th) anniversary of the Series B Preferred Stock Issue Date, then the "Series E Redemption Price" shall mean the greater of (i) $26.239 per share, plus an amount equal to all dividends accrued and unpaid on each such share and (ii) the Fair Market Value (as defined below) of the Common Stock underlying the Series E Convertible Preferred Stock. Such payment shall be made in full on the Redemption Date to the holders entitled thereto. For purposes of this paragraph 7B, "Fair Market Value" of the Common Stock shall mean the average of the fair market valuations of the Common Stock performed by two investment banks (the "Initial Appraisers"), one of which shall be retained by the Corporation and one of which shall be retained by the holders of a majority in interest of the Series E Convertible Preferred Stock. Subject to the following sentence, such determination by the Initial Appraisers of Fair Market Value shall be final and binding on the parties. If the higher of the two valuations of the Initial Appraisers is equal to or greater than 110% of the lower valuation, the Corporation and holders of a majority in interest of the Series E Convertible Preferred Stock shall select a third investment bank (the "Final Appraiser"), which shall be mutually agreeable to the Corporation and the holders of a majority in interest of the Series E Convertible Preferred Stock. The fair market value of the Common Stock as determined by the Final Appraiser shall be final and binding on the parties. The fees and expenses of the Initial Appraisers shall be paid for by the party selecting such Initial Appraiser and the fees and expenses of the Final Appraiser shall be shared by the Corporation and the holders of the Series E Convertible Preferred Stock. 7C. Redemption Mechanics. At least 15 but not more than 35 days prior to the Redemption Date, written notice (the "Redemption Notice") shall be given by the Corporation

94 by mail, postage prepaid, or by facsimile transmission to non-U.S. residents, to each holder of record (at the close of business on the business day next preceding the day on which the Redemption Notice is given) of shares of Series E Convertible Preferred Stock notifying such holder of the redemption and specifying the Series E Redemption Price, the Redemption Date and the place where said Series E Redemption Price shall be payable. The Redemption Notice shall be addressed to each holder at his address as shown by the records of the Corporation. From and after the close of business on the Redemption Date, unless there shall have been a default in the payment of the Series E Redemption Price, all rights of holders of shares of Series E Convertible Preferred Stock (except the right to receive the Series E Redemption Price) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Series E Convertible Preferred Stock on the Redemption Date are insufficient to redeem the total number of outstanding shares of Series E Convertible Preferred Stock to be redeemed on such Redemption Date, the holders of shares of Series E Convertible Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the full number of shares owned by them if all such outstanding shares were redeemed in full. The shares of Series E Convertible Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein; provided, however, that such unredeemed shares shall be entitled to receive interest accruing daily with respect to the applicable Series E Redemption Price at the rate of 15% per annum, payable quarterly in arrears. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series E Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 7D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series E Convertible Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series E Convertible Preferred Stock. 8. Amendments. Except where the vote or written consent of the holders of a different number of shares of the Corporation is required by these terms of the Series E Convertible Preferred Stock, by law or by the Certificate of Incorporation, no provision of these terms of the Series E Convertible Preferred Stock may be amended, modified or waived without the written consent or affirmative vote of the holders of at least 60% of the then outstanding shares of Series E Convertible Preferred Stock. 9. Definitions. As used herein, the following terms shall have the following meanings: (1) The term "Founders" shall mean F. Thomson Leighton, Daniel Lewin, Jonathan Seelig, Randall Kaplan, Gilbert Friesen and David Karger.

(5) The term "Reserved Employee Shares" shall mean shares of Common Stock reserved by the Corporation pursuant to the Plan from time to time for (i) the sale of shares of Common Stock to employees, consultants or non-employee directors (other than representatives of the holders of Preferred Stock) of the Corporation or (ii) the exercise of options to purchase Common Stock granted to employees, consultants or non-employee directors (other than representatives of the holders of Preferred Stock) of the Corporation, not to exceed in the aggregate 11,377,800 shares of Common Stock for both clauses (i) and (ii), with such number including 2,132,100 shares issued or subject to options granted prior to the date of the initial issuance of the Series A Convertible Preferred Stock (the "Option Shares") (appropriately adjusted to reflect an event described in paragraph 6F hereof); provided that, such number of such shares subject to the Plan shall be increased by up to 7,559,226 additional shares of Common Stock (appropriately adjusted to reflect an event described in paragraph 6F hereof) (collectively, the "Founders' Shares") upon the repurchase of such Founders' Shares by the Corporation from the Founders pursuant to contractual rights held by the Corporation. The foregoing numbers of Reserved Employee Shares may be increased by the affirmative vote or written consent of a majority of the directors designated solely by the holders of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock and Series E Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis.

The holders of shares of the Series F Convertible Preferred Stock shall be entitled to receive, when, as and if dividends are declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative preferential dividends at the annual rate of 8% on the Series F Liquidation Preference Payments (as defined in paragraph 4A herein); provided, however, that any such dividends shall only be paid, whether declared or not, immediately upon the occurrence of (i) a Liquidation Event pursuant to paragraph 4A hereof or (ii) a Redemption pursuant to paragraph 7B hereof. Holders of shares of Series F Convertible Preferred Stock shall be entitled to receive the dividends provided for herein in preference to and in priority over any dividends upon any of the Junior Securities. Dividends on the Series F Convertible Preferred Stock shall accrue on a daily basis from the Preferred Stock Issue Date and, to the extent they are not paid, shall accumulate on an annual basis on each December 31, whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of such dividends and whether or not dividends are declared. 4. Liquidation, Dissolution and Winding-up. 4A. Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (a "Liquidation Event"), whether voluntary or involuntary, the holders of the shares of Series F Convertible Preferred Stock shall be paid an amount equal to $15.22 per share plus, in the case if each share, an amount equal to dividends accrued but unpaid thereon, computed to the date payment thereof is made available, together with payment to any Pari Passu Securities, and before any payment shall be made to the holders of any Junior Securities, such amount payable with respect to one share of Series F Convertible Preferred Stock being sometimes referred to as the "Series F Liquidation Preference Payment" and with respect to all shares of Series F Convertible Preferred Stock being sometimes referred to as the "Series F Liquidation Preference Payments". If upon any Liquidation Event, the assets to be distributed to the holders of the Series F Convertible Preferred Stock shall be insufficient to permit payment to such stockholders of the full preferential amounts aforesaid, then all of the assets of the Corporation available for distribution to holders of the Series F Convertible Preferred Stock and Pari Passu Securities shall be distributed to such holders of the Series F Convertible Preferred Stock and Pari Passu Securities pro rata, so that each holder receives that portion of the assets available for distribution as the number of shares of such stock held by such holder bears to the total number of shares of such stock then outstanding. 4B. Upon any Liquidation Event, immediately after the holders of Series F Convertible Preferred Stock and holders of any Pari Passu Securities have been paid in full pursuant to paragraph 4A above, the remaining net assets of the Corporation available for distribution shall be distributed among the holders of the shares of Junior Securities. Written notice of such Liquidation Event, stating a payment date and the place where said payments shall be made, shall be given by mail, postage prepaid, or by facsimile to non-U.S. residents, not less than 20 days prior to the payment date stated therein, to the holders of record of Series F Convertible Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. The (x) consolidation or merger of the Corporation into or with any other entity or entities which results in the exchange of outstanding shares of the Corporation for securities or other consideration issued or paid or caused to be issued or paid by any such entity or affiliate 3

102 thereof (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving Corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction), (y) sale or transfer by the Corporation of all or substantially all of its assets, or (z) sale or transfer by the Corporation's stockholders of capital stock representing a majority of the outstanding capital stock of the Corporation shall be deemed to be a Liquidation Event within the meaning of the provisions of this paragraph 4 (subject to the provisions of this paragraph 4 and not the provisions of paragraph 6G hereof, unless paragraph 6G is elected in the following proviso); provided, however, that if the holders of at least 60% of the then outstanding shares of Series F Convertible Preferred Stock shall elect the benefits of the provisions of paragraph 6G in lieu of receiving payment in a Liquidation Event pursuant to this paragraph 4, then all holders of shares of Series F Convertible Preferred Stock shall receive the benefits of the provisions of paragraph 6G in lieu of receiving payment pursuant to this paragraph 4 for the particular Organic Change (as defined in Section 6G) causing the rights of Section 6G to be available. The election of the rights under Section 6G for any particular Organic Change shall not constitute an election of the rights available under Section 6G for any other Organic Change, for which the holders of Series F Convertible Preferred Stock shall have a new election under the foregoing proviso. Whenever the distribution provided for in this paragraph 4 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. 5. Restrictions. At any time when at least 50% of the shares of Series F Convertible Preferred Stock issued pursuant to the Purchase Agreement remain outstanding, except where the vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or the Certificate of Incorporation, without the written consent of the holders of at least 60% of the then outstanding shares of Series F Convertible Preferred Stock given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a series, the Corporation will not: (1) Consent to any Liquidation Event or merge or consolidate with or into, or permit any Subsidiary to merge or consolidate with or into, any other corporation, corporations, entity or entities (except a consolidation or merger into a Subsidiary or merger in which the Corporation is the surviving corporation and the holders of the Corporation's voting stock outstanding immediately prior to the transaction constitute a majority of the holders of voting stock outstanding immediately following the transaction or a consolidation or merger pursuant to which the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $1.2 billion) without the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock and Series F Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis; (2) Sell, abandon, transfer, lease or otherwise dispose of all or substantially all of its properties or assets (unless the aggregate consideration definitely and unconditionally payable to all of the stockholders of the Corporation is greater than $1.2 billion) without the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares 4

103 of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock and Series F Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis; (3) Amend, alter or repeal any provision of its Certificate of Incorporation or By-laws in a manner adverse to holders of the Series F Convertible Preferred Stock; (4) Create or authorize the creation of or issue any additional class or series of shares of stock (other than the Series C Convertible Preferred Stock of the Corporation) unless the same ranks junior to or on parity with the Series F Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or increase the authorized amount of Series F Convertible Preferred Stock or increase the authorized amount of any additional class or series of shares of stock unless the same ranks junior to or on parity with the Series F Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, or create or authorize any obligation or security convertible into shares of Series F Convertible Preferred Stock or into shares of any other class or series of stock unless the same ranks junior to or on parity with the Series F Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event, whether any such creation, authorization or increase shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; (5) In any manner amend, alter or change the designations or the powers, preferences or rights, privileges or the restrictions of the Series F Convertible Preferred Stock, provided, however, that the authorization or creation of any shares of capital stock on parity with the Series F Convertible Preferred Stock as to dividends and the distribution of assets on a Liquidation Event shall not require the approval of holders of Series F Convertible Preferred Stock; (6) Purchase or redeem, or set aside any sums for the purchase or redemption of, or pay any dividend or make any distribution on, any Junior Securities, except for (i) dividends or other distributions payable on the Common Stock solely in the form of additional shares of Common Stock or (ii) repurchases of shares of capital stock (at the original purchase price therefor) from officers, employees, directors or consultants of the Corporation which are subject to restrictive stock purchase, right of first refusal or other agreements under which the Corporation has the option to repurchase such shares upon the occurrence of certain events, including termination of employment; or (7) Increase the number of Reserved Employee Shares without the affirmative vote or written consent of a majority of the directors designated solely by the holders of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock or the affirmative vote or written consent of the holders of at least 50% of the then outstanding shares of Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock and Series F Convertible Preferred Stock, voting together as a single class on a Common Stock equivalent basis. 6. Conversion. The holders of shares of Series F Convertible Preferred Stock shall have the following conversion rights: 5

104 6A. Right to Convert. Subject to the terms and conditions of this paragraph 6, the holder of any share or shares of Series F Convertible Preferred Stock shall have the right, at its option at any time, to convert any such shares of Series F Convertible Preferred Stock (except that upon any Liquidation Event the right of conversion shall terminate at the close of business on the business day fixed for payment of the amounts distributable on the Series F Convertible Preferred Stock) into such number of fully paid and nonassessable shares of Common Stock as is obtained by (i) multiplying the number of shares of Series F Convertible Preferred Stock so to be converted by $15.22 and (ii) dividing the result by the conversion price of $15.22 per share or in case an adjustment of such price has taken place pursuant to the further provisions of this paragraph 6, then by the conversion price as last adjusted and in effect at the date any share or shares of Series F Convertible Preferred Stock are surrendered for conversion (such price, or such price as last adjusted, being referred to as the "Series F Conversion Price"). Such rights of conversion shall be exercised by the holder thereof by giving written notice that the holder elects to convert a stated number of shares of Series F Convertible Preferred Stock into Common Stock and by surrender of a certificate or certificates for the shares so to be converted to the Corporation at its principal office (or such other office or agency of the Corporation as the Corporation may designate by notice in writing to the holders of the Series F Convertible Preferred Stock) at any time during its usual business hours on the date set forth in such notice, together with a statement of the name or names (with address) in which the certificate or certificates for shares of Common Stock shall be issued. 6B. Issuance of Certificates; Time Conversion Effected. Promptly after the receipt of the written notice referred to in paragraph 6A and surrender of the certificate or certificates for the share or shares of Series F Convertible Preferred Stock to be converted, the Corporation shall issue and deliver, or cause to be issued and delivered, to the holder, registered in such name or names as such holder may direct, a certificate or certificates for the number of whole shares of Common Stock issuable upon the conversion of such share or shares of Series F Convertible Preferred Stock. To the extent permitted by law, such conversion shall be deemed to have been effected and the Series F Conversion Price shall be determined as of the close of business on the date on which such written notice shall have been received by the Corporation and the certificate or certificates for such share or shares shall have been surrendered as aforesaid, and at such time the rights of the holder of such share or shares of Series F Convertible Preferred Stock shall cease, and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the shares represented thereby. 6C. Fractional Shares; Dividends; Partial Conversion. No fractional shares shall be issued upon conversion of Series F Convertible Preferred Stock into Common Stock and no payment or adjustment shall be made upon any conversion on account of any cash dividends on the Common Stock issued upon such conversion. At the time of each conversion, the Corporation shall pay in cash an amount equal to all dividends declared and unpaid (if any) on the shares of Series F Convertible Preferred Stock surrendered for conversion to the date upon which such conversion is deemed to take place as provided in paragraph 6B. In case the number of shares of Series F Convertible Preferred Stock represented by the certificate or certificates surrendered pursuant to paragraph 6A exceeds the number of shares converted, the Corporation shall, upon such conversion, execute and deliver to the holder, at the expense of the Corporation, a new certificate or certificates for the number of shares of Series F Convertible 6

105 Preferred Stock represented by the certificate or certificates surrendered which are not to be converted. If any fractional share of Common Stock would, except for the provisions of the first sentence of this paragraph 6C, be delivered upon such conversion, the Corporation, in lieu of delivering such fractional share, shall pay to the holder surrendering the Series F Convertible Preferred Stock for conversion an amount in cash equal to the current fair market value of such fractional share as determined in good faith by the Board of Directors of the Corporation, and based upon the aggregate number of shares of Series F Convertible Preferred Stock surrendered by any one holder. 6D. Adjustment of Series F Conversion Price Upon Issuance of Common Stock. Except as provided in paragraphs 6E and 6F, if and whenever the Corporation shall issue or sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to have issued or sold, any shares of Common Stock for a consideration per share less than the Series F Conversion Price in effect immediately prior to the time of such issue or sale, (such number being appropriately adjusted to reflect the occurrence of any event described in paragraph 6F), then, forthwith upon such issue or sale, the Series F Conversion Price shall be reduced to the price determined by dividing (i) an amount equal to the sum of (a) the number of shares of Common Stock outstanding immediately prior to such issue or sale (assuming the conversion of the outstanding shares of Series F Convertible Preferred Stock) multiplied by the then existing Series F Conversion Price and (b) the consideration, if any, received by the Corporation upon such issue or sale, by (ii) the total number of shares of Common Stock outstanding immediately after such issue or sale (assuming the conversion of the outstanding shares of Series F Convertible Preferred Stock). For purposes of this paragraph 6D, the following subparagraphs 6D(1) to 6D(7) shall also be applicable: 6D(1) Issuance of Rights or Options. In case at any time the Corporation shall in any manner grant (whether directly or by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the granting of such Options, plus the minimum aggregate amount of additional consideration payable to the Corporation upon the exercise of all such Options, plus, in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of all such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Series F Conversion Price in effect immediately prior to the time of the granting of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion 7

106 or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding. Except as otherwise provided in subparagraph 6D(3), no adjustment of the Series F Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 6D(2) Issuance of Convertible Securities. In case the Corporation shall in any manner issue (whether directly or by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the total amount received or receivable by the Corporation as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of all such Convertible Securities thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Series F Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding, provided that (a) except as otherwise provided in subparagraph 6D(3), no adjustment of the Series F Conversion Price shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities and (b) if any such issue or sale of such Convertible Securities is made upon exercises of any Options to purchase any such Convertible Securities for which adjustments of the Series F Conversion Price have been or are to be made pursuant to other provisions of this paragraph 6D, no further adjustment of the Series F Conversion Price shall be made by reason of such issue or sale. 6D(3) Change in Option Price or Conversion Rate. Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in subparagraph 6D(1), the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subparagraph 6D(1) or 6D(2), or the rate at which Convertible Securities referred to in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Series F Conversion Price in effect at the time of such event shall forthwith be readjusted to the Series F Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold; provided, however, that in no event shall the Series F Conversion Price then in effect hereunder be increased; and on the expiration of any such Option or the termination of any such right to convert or exchange such Convertible Securities, the Series F Conversion Price then in effect 8

107 hereunder shall forthwith be increased to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued. 6D(4) Stock Dividends. In case the Corporation shall declare a dividend or make any other distribution upon any stock of the Corporation payable in Common Stock (except for the issue of stock dividends or distributions upon the outstanding Common Stock for which adjustment is made pursuant to paragraph 6F), Options or Convertible Securities, any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration. 6D(5) Consideration for Stock. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Corporation therefor, without deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for consideration other than cash, the amount of the consideration other than cash received by the Corporation shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Corporation, without deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Corporation in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Corporation, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Corporation. 6D(6) Record Date. In case the Corporation shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. 6D(7) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation (or any Subsidiary), and the disposition of any such shares shall be considered an issue or sale of Common Stock for the purpose of this paragraph 6D. 6E. Certain Issues Excepted. Anything herein to the contrary notwithstanding, the Corporation shall not be required to make any adjustment of the Series F Conversion Price if it first obtains the written consent of the holders of at least 60% of the then outstanding shares of Series F Convertible Preferred Stock that no adjustment shall be required. In no event shall the Corporation be required to make any adjustment to the Series F 9

108 Conversion Price in the case of the issuance of (i) shares of Series C Convertible Preferred Stock pursuant to the Series B Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock or Series F Convertible Preferred Stock, (iii) shares of Common Stock issued or issuable as a dividend or distribution on Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series C Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock or Series F Convertible Preferred Stock, (iv) Reserved Employee Shares (as defined in paragraph 9 herein), (v) warrants issued in connection with senior subordinated notes of the Corporation as contemplated by the Series B Purchase Agreement or shares of Common Stock issuable upon conversion of such warrants, or (vi) Options outstanding as of the Preferred Stock Issue Date. 6F. Subdivision or Combination of Common Stock. In case the Corporation shall at any time subdivide (by any stock split, stock dividend or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Series F Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and, conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares, the Series F Conversion Price in effect immediately prior to such combination shall be proportionately increased. 6G. Reorganization or Reclassification. If any capital reorganization, reclassification, recapitalization, consolidation, merger, sale of all or substantially all of the Corporation's assets or other similar transaction (any such transaction being referred to herein as an "Organic Change") shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, then, as a condition of such Organic Change, lawful and adequate provisions shall be made whereby each holder of a share or shares of Series F Convertible Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of or in addition to, as the case may be, the shares of Common Stock immediately theretofore receivable upon the conversion of such share or shares of Series F Convertible Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such Common Stock immediately theretofore receivable upon such conversion had such Organic Change not taken place, and in any case of a reorganization or reclassification only appropriate provisions shall be made with respect to the rights and interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Series F Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise of such conversion rights. 6H. Notice of Adjustment. Upon any adjustment of the Series F Conversion Price, then and in each such case the Corporation shall give written notice thereof, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of shares of Series F Convertible Preferred Stock at the address of such holder as shown on the books of the Corporation, which notice shall state the Series F Conversion Price resulting from such adjustment, setting forth in reasonable detail the method upon which such calculation is based. 10

109 6I. Other Notices. In case at any time: (1) the Corporation shall declare any dividend upon its Common Stock payable in cash or stock or make any other distribution to the holders of its Common Stock; (2) the Corporation shall offer for subscription pro rata to the holders of its Common Stock any additional shares of stock of any class or other rights; (3) there shall be any capital reorganization or reclassification of the capital stock of the Corporation, or a consolidation or merger of the Corporation with or into, or a sale of all or substantially all of its assets to, another entity or entities; or (4) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then, in any one or more of said cases, the Corporation shall give, by first class mail, postage prepaid, or by facsimile transmission to non-U.S. residents, addressed to each holder of any shares of Preferred Stock at the address of such holder as shown on the books of the Corporation, (a) at least 20 days' prior written notice of the date on which the books of the Corporation shall close or a record shall be taken for such dividend, distribution or subscription rights or for determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, at least 20 days' prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common Stock shall be entitled thereto and such notice in accordance with the foregoing clause (b) shall also specify the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. 6J. Stock to be Reserved. The Corporation will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issuance upon the conversion of Series F Convertible Preferred Stock as herein provided, such number of shares of Common Stock as shall then be issuable upon the conversion of all outstanding shares of Series F Convertible Preferred Stock. The Corporation covenants that all shares of Common Stock which shall be so issued shall be duly and validly issued and fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof, and, without limiting the generality of the foregoing, the Corporation covenants that it will from time to time take all such action as may be requisite to assure that the par value per share of the Common Stock is at all times equal to or less than the Series F Conversion Price in effect at the time. The Corporation will take all such action as may be necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or regulation, or of any requirement of any national securities exchange upon which the Common Stock may be listed. 6K. No Reissuance of Series F Convertible Preferred Stock. Shares of Series F Convertible Preferred Stock which are converted into shares of Common Stock as provided 11

110 herein shall not be reissued. 6L. Issue Tax. The issuance of certificates for shares of Common Stock upon conversion of Series F Convertible Preferred Stock shall be made without charge to the holders thereof for any issuance tax in respect thereof; provided that the Corporation shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the holder of the Series F Convertible Preferred Stock which is being converted. 6M. Closing of Books. The Corporation will at no time close its transfer books against the transfer of any Series F Convertible Preferred Stock or of any shares of Common Stock issued or issuable upon the conversion of any shares of Series F Convertible Preferred Stock in any manner which interferes with the timely conversion of such Preferred Stock, except as may otherwise be required to comply with applicable securities laws. 6N. Definition of Common Stock. As used in this paragraph 6, the term "Common Stock" shall mean and include the Corporation's authorized Common Stock, par value $.01 per share, as constituted on the date of filing of these terms of the Series F Convertible Preferred Stock, and shall also include any capital stock of any class of the Corporation thereafter authorized which shall neither be limited to a fixed sum or percentage of par value in respect of the rights of the holders thereof to participate in dividends nor entitled to a preference in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; provided that the shares of Common Stock receivable upon conversion of shares of Series F Convertible Preferred Stock shall include only shares designated as Common Stock of the Corporation on the date of filing of this instrument, or in case of any reorganization or reclassification of the outstanding shares thereof, the stock, securities or assets provided for in subparagraph 6G. 6O. Mandatory Conversion. All outstanding shares of Series F Convertible Preferred Stock shall automatically convert to shares of Common Stock if at any time the Corporation shall effect a public offering of shares of Common Stock (any such offering, regardless of compliance with subsections (i), (ii) and (iii) herein, being referred to as a "Public Offering"), provided (i) the aggregate gross proceeds from such offering to the Corporation shall be at least $20,000,000, (ii) the price paid by the public for such shares shall be at least (x) 2.0 times the then Series B Conversion Price if the Public Offering occurs prior to the 18 month anniversary of the Series B Preferred Stock Issue Date or (y) 3.0 times the then Series B Conversion Price if the Public Offering occurs on or after the 18 month anniversary of the Series B Preferred Stock Issue Date and (iii) the offering is a firm commitment underwritten Public Offering, and such automatic conversion shall be effective upon the closing of the sale of such shares by the Corporation pursuant to such Public Offering. 12

111 7. Redemption. The shares of Series F Convertible Preferred Stock shall be redeemed as follows: 7A. Optional Redemption. The Corporation shall not have the right to call or redeem at any time all or any shares of Series F Convertible Preferred Stock. With the approval of the holders of 66% of the then outstanding shares of Series F Convertible Preferred Stock, one or more holders of shares of Series F Convertible Preferred Stock may, by giving notice (the "Notice") to the Corporation, require the Corporation to redeem any or all of the outstanding Series F Convertible Preferred Stock on the Redemption Date (as defined below). Upon receipt of the Notice, the Corporation will so notify all other persons holding Series F Preferred Convertible Stock. After receipt of the Notice, the Corporation shall fix the first date for redemption, which shall be the date specified in the Notice, being any date on or after the earlier of (i) the fifth (5th) anniversary of the Series B Preferred Stock Issue Date and (ii) the date which is the day before the Corporation is due to redeem any outstanding Junior Securities (the "Redemption Date"). All holders of the Series F Convertible Preferred Stock shall deliver to the Corporation during regular business hours, at the office of any transfer agent of the Corporation for the Series F Convertible Preferred Stock, or at the principal office of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the Series F Convertible Preferred Stock, duly endorsed for transfer to the Corporation (if required by it) on or before the Redemption Date. 7B. Redemption Price and Payment. The Series F Convertible Preferred Stock to be redeemed on the Redemption Date shall be redeemed by paying for each share in cash an amount equal to the Series F Redemption Price (as defined below). For purposes of this paragraph 7B, the "Series F Redemption Price" shall mean $15.22 per share, plus an amount equal to all dividends accrued and unpaid on each such share; provided, however, that if the Redemption Date is after the fifth (5th) anniversary of the Series B Preferred Stock Issue Date, then the "Series F Redemption Price" shall mean the greater of (i) $15.22 per share, plus an amount equal to all dividends accrued and unpaid on each such share and (ii) the Fair Market Value (as defined below) of the Common Stock underlying the Series F Convertible Preferred Stock. Such payment shall be made in full on the Redemption Date to the holders entitled thereto. For purposes of this paragraph 7B, "Fair Market Value" of the Common Stock shall mean the average of the fair market valuations of the Common Stock performed by two investment banks (the "Initial Appraisers"), one of which shall be retained by the Corporation and one of which shall be retained by the holders of a majority in interest of the Series F Convertible Preferred Stock. Subject to the following sentence, such determination by the Initial Appraisers of Fair Market Value shall be final and binding on the parties. If the higher of the two valuations of the Initial Appraisers is equal to or greater than 110% of the lower valuation, the Corporation and holders of a majority in interest of the Series F Convertible Preferred Stock shall select a third investment bank (the "Final Appraiser"), which shall be mutually agreeable to the Corporation and the holders of a majority in interest of the Series F Convertible Preferred Stock. The fair market value of the Common Stock as determined by the Final Appraiser shall be final and binding on the parties.

At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Series F Convertible Preferred Stock, such funds will be used, at the end of the next succeeding fiscal quarter, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 7D. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of Series F Convertible Preferred Stock redeemed pursuant to this paragraph 7 or otherwise acquired by the Corporation in any manner whatsoever shall be canceled and shall not under any circumstances be reissued; and the Corporation may from time to time take such appropriate corporate action as may be necessary to reduce accordingly the number of authorized shares of Series F Convertible Preferred Stock. 8.

(c) The only securities which the Company shall be required to register pursuant to this Section 2 shall be shares of Common Stock; provided, however, that, in any underwritten public offering contemplated by this Section 2 or Sections 3 and 4, the holders of Preferred Shares shall be entitled to sell such Preferred Shares to the underwriters for conversion and sale of the shares of Common Stock issued upon conversion thereof. Notwithstanding anything to the contrary contained herein, the Company shall not be required to effect a registration of shares of its Common Stock pursuant to this Section 2 within 180 days after the effective date of a registration statement filed by the Company covering a firm commitment underwritten public offering in which the holders of Restricted Stock shall have been entitled to join pursuant to Sections 3 or 4. (d) Following receipt of any notice under subsection 2(a), the Company shall immediately notify all holders of Original Restricted Stock (including the Founders) from whom notice has not been received and such holders shall then be entitled within 30 days thereafter to request the Company to include in the requested registration all or any portion of their shares of Original Restricted Stock. The Company shall use its best efforts to register under the Securities Act, for public sale in accordance with the method of disposition described in subsection 2(a), the number of shares of Original Restricted Stock specified in such notice (and in all notices received by the Company from other holders within 30 days after the 5

6 giving of such notice by the Company). The Company shall be obligated to register Original Restricted Stock pursuant to subsection 2(a) on two occasions only as follows: (i) one at the request of Series A Purchasers holding Original Restricted Stock who have so requested pursuant to clause (i) of subsection 2(a) and (ii) one at the request of holders of Common Stock who have so requested pursuant to clause (ii) of subsection 2(a); PROVIDED, HOWEVER, that such obligation shall be deemed satisfied only when a registration statement, covering all of the offered shares of Original Restricted Stock specified in notices received as aforesaid for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective or if such registration statement has been withdrawn prior to the consummation of the offering at the request of the Series A Purchasers (other than as a result of a material adverse change in the business or financial condition of the Company) and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto. (e) Following receipt of any notice under subsection 2(b), the Company shall immediately notify all holders of Series B/C/D/E/F Restricted Stock from whom notice has not been received and such holders shall then be entitled within 30 days thereafter to request the Company to include in the requested registration all or any portion of their shares of Series B/C/D/E/F Restricted Stock. The Company shall use its best efforts to register under the Securities Act, for public sale in accordance with the method of disposition described in subsection 2(b), the number of shares of Series B/C/D/E/F Restricted Stock specified in such notice (and in all notices received by the Company from other holders within 30 days after the giving of such notice by the Company). The Company shall be obligated to register Series B/C/D/E/F Restricted Stock pursuant to subsection 2(b) on three occasions only; provided, however, that such obligation shall be deemed satisfied only when a registration statement, covering all of the offered shares of Series B/C/D/E/F Restricted Stock specified in notices received as aforesaid for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective or if such registration statement has been withdrawn prior to the consummation of the offering at the request of the Series B Purchasers, the Series D Purchaser, the Series E Purchaser or the Series F Purchaser (other than as a result of a material adverse change in the business or financial condition of the Company) and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto, or, if such method of disposition includes the resale of the shares from time to time at prevailing market prices, such registration statement has remained effective and available for resale for at least 120 days. (f) The Company (or at the option of the Company, the holders of Common Stock) shall be entitled to include in any registration statement referred to in this Section 2, for sale in accordance with the method of disposition specified by the requesting holders, shares of Common Stock to be sold by the Company for its own account or the account of such other holders, except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Restricted Stock to be sold subject to the limitations set forth in subsection 2(g) hereof). Except for registration statements on Form S-4, S-8 or any successor thereto, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of other stockholders, from the 6

7 date of receipt of a notice from requesting holders pursuant to this Section 2 until the completion of the period of distribution of the registration contemplated thereby. (g) If, in the opinion of the managing underwriter, the inclusion of all of the Restricted Stock requested to be registered under this Section would adversely affect the marketing of such shares, then, (i) in the case of a registration requested pursuant to clause (i) of subsection 2(a), shares to be sold by the Company or other holders of Common Stock (including the Founders) shall first be excluded, and then if necessary, shares of Original Restricted Stock to be sold by the Series A Purchasers shall be excluded in such manner that the shares to be sold shall be allocated among the Series A Purchasers selling Original Restricted Stock pro rata based on their ownership of Original Restricted Stock, (ii) in the case of a registration requested pursuant to clause (ii) of subsection 2(a), shares to be sold by the Company or any other holders of Common Stock (excluding the Founders and including any shares of Original Restricted Stock held by the Series A Purchasers) shall first be excluded, and then if necessary, shares of Original Restricted Stock to be sold by the Founders shall be excluded in such manner that the shares to be sold shall be allocated among the Founders selling Original Restricted Stock pro rata based on their ownership of Original Restricted Stock, and (iii) in the case of a registration requested pursuant to subsection 2(b), shares to be sold by the Company or other holders of Common Stock shall first be excluded, and then if necessary, shares of Series B/C/D/E/F Restricted Stock to be sold by the Series B Purchasers, the Series D Purchaser, the Series E Purchaser and the Series F Purchaser shall be excluded in such a manner that the shares to be sold shall be allocated among the Series B Purchasers, the Series D Purchaser, the Series E Purchaser and the Series F Purchaser selling Series B/C/D/E/F Restricted Stock pro rata based on their ownership of Series B/C/D/E/F Restricted Stock; provided, however, that in any registration in which both the Series A Purchasers and Founders shall have requested registration pursuant to both clauses (i) and (ii) of subsection 2(a), then shares to be sold by the Company or other holders of Common Stock (including the Founders) shall first be excluded, and then if necessary, shares of Original Restricted Stock to be sold by the Series A Purchasers shall be excluded in such manner that the shares to be sold shall be allocated among the Series A Purchasers selling Original Restricted Stock pro rata based on their ownership of Original Restricted Stock. 3. INCIDENTAL REGISTRATION. If, following the Company's first registered public offering of its Common Stock, the Company at any time (other than pursuant to Section 2 or Section 4) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account only or for its own account and for the account of other security holders (except with respect to registration statements on Forms S-4, S-8 or another form not available for registering the Restricted Stock for sale to the public), each such time it will give written notice to all Purchasers holding outstanding Restricted Stock of its intention so to do. Upon the written request of any such holder received by the Company within 30 days after the giving of any such notice by the Company to register at least 900,000 shares (appropriately adjusted for any of the events specified in Section 8 herein) of its Restricted Stock, the Company will use its best efforts to cause the Restricted Stock as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by the 7

8 holder (in accordance with such written request) of such Restricted Stock so registered. In the event that any registration pursuant to this Section 3 shall be, in whole or in part, an underwritten public offering of Common Stock, the number of shares of Restricted Stock to be included in such an underwriting may be reduced (pro rata among the requesting holders based upon the number of shares of Restricted Stock held by such requesting holders) if and to the extent that the managing underwriter shall be of the opinion that such inclusion would adversely affect the marketing of the securities to be sold by the Company therein, but in no event shall the amount of securities of the requesting holders be reduced below thirty percent (30%) of the total amount to be included in such offering; provided, however, that such number of shares of Restricted Stock shall not be reduced if any shares are to be included in such underwriting for the account of any person (including the Founders) other than the Company or requesting Purchasers holding Restricted Stock. Notwithstanding the foregoing provisions, the Company may withdraw any registration statement referred to in this Section 3 without thereby incurring any liability to the holders of Restricted Stock. 4. REGISTRATION ON FORM S-3. (a) If at any time (i) a holder or holders of Restricted Stock then outstanding request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of the shares of Restricted Stock held by such requesting holder or holders, the reasonably anticipated aggregate price to the public of which would exceed $1,000,000, and (ii) the Company is a registrant entitled to use Form S-3 or any successor thereto to register such shares, then the Company shall use its best efforts to register under the Securities Act on Form S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the number of shares of Restricted Stock specified in such notice. Whenever the Company is required by this Section 4 to use its best efforts to effect the registration of Restricted Stock, each of the procedures and requirements of Section 2 (including but not limited to the requirement that the Company notify all holders of Restricted Stock from whom notice has not been received and provide them with the opportunity to participate in the offering) shall apply to such registration, PROVIDED, HOWEVER, that no more than two (2) registrations on Form S-3 may be requested and obtained under this Section 4 within any twelve (12) month period preceding the date of such request. (b) Notwithstanding anything to the contrary set forth in this Agreement, the Company's obligation under this Agreement to register Restricted Stock under the Securities Act on registration statements ("REGISTRATION STATEMENTS") may, upon the reasonable determination of the Board of Directors made only once during any 12-month period, be suspended in the event and during such period as unforeseen circumstances (including without limitation (i) an underwritten primary offering by the Company (which includes no secondary offering) if the Company is advised in writing by its underwriters that the registration of the Restricted Stock would have a material adverse effect on the Company's offering, or (ii) pending negotiations relating to, or consummation of, a transaction or the occurrence of an event which would require additional disclosure of material information by the Company in Registration Statements or such other filings, as to which the Company has a bona fide business purpose for preserving confidentiality or which renders the Company unable to comply with the Commission's 8

9 requirements) exist (such unforeseen circumstances being hereinafter referred to as a "SUSPENSION EVENT") which would make it impractical or inadvisable for the Company to file the Registration Statements or such other filings or to cause such to become effective. Such suspension shall continue only for so long as such event is continuing but in no event for a period longer than ninety (90) days. The Company shall notify the Purchasers of the existence and nature of any Suspension Event. 5. REGISTRATION PROCEDURES. If and whenever the Company is required by the provisions of Sections 2, 3 or 4 to use its best efforts to effect the registration of any shares of Restricted Stock under the Securities Act, the Company will, as expeditiously as possible: (a) prepare and file with the Commission a registration statement (which, in the case of an underwritten public offering pursuant to Section 2, shall be on Form S-1 or other form of general applicability satisfactory to the managing underwriter selected as therein provided) with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for the period of the distribution contemplated thereby (determined as hereinafter provided); (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for the period specified in paragraph (a) above and comply with the provisions of the Securities Act with respect to the disposition of all Restricted Stock covered by such registration statement in accordance with the sellers' intended method of disposition set forth in such registration statement for such period; (c) furnish to each seller of Restricted Stock and to each underwriter such number of copies of the registration statement and each such amendment and supplement thereto (in each case including all exhibits) and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Restricted Stock covered by such registration statement; (d) use its best efforts to register or qualify the Restricted Stock covered by such registration statement under the securities or "BLUE SKY" laws of such jurisdictions as the sellers of Restricted Stock or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; PROVIDED, HOWEVER, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction; (e) use its best efforts to list the Restricted Stock covered by such registration statement with any securities exchange on which the Common Stock of the Company is then listed; 9

10 (f) immediately notify each seller of Restricted Stock and each underwriter under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly prepare and furnish to such seller a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to the purchasers of such Restricted Stock, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; (g) if the offering is underwritten and at the request of any seller of Restricted Stock, use its best efforts to furnish to such seller on the date that Restricted Stock is delivered to the underwriters for sale pursuant to such registration: (i) a copy of an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters and to such seller, to such effect as reasonably may be requested by counsel for the underwriters, and (ii) a letter dated such date from the independent public accountants retained by the Company, addressed to the underwriters and to such seller, stating that they are independent public accountants within the meaning of the Securities Act and that, in the opinion of such accountants, the financial statements of the Company included in the registration statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five business days prior to the date of such letter) with respect to such registration as such underwriters reasonably may request; (h) make available for inspection by each seller of Restricted Stock, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by such seller or underwriter, reasonable access to all financial and other records, pertinent corporate documents and properties of the Company, as such parties may reasonably request, and cause the Company's officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; (i) cooperate with the selling holders of Restricted Stock and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Restricted Stock to be sold, such certificates to be in such denominations and registered in such names as such holders or the managing underwriters may request at least two business days prior to any sale of Restricted Stock; and (j) permit any holder of Restricted Stock which holder, in the sole and exclusive judgment, exercised in good faith, of such holder, might be deemed to be a controlling person of the Company, to participate in good faith in the preparation of such registration or 10

11 comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such holder and its counsel should be included. For purposes of Section 5(a) and 5(b) and of Section 2(f), the period of distribution of Restricted Stock in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Restricted Stock in any other registration shall be deemed to extend until the earlier of the sale of all Restricted Stock covered thereby and 180 days after the effective date thereof. In connection with each registration hereunder, the sellers of Restricted Stock will furnish to the Company in writing such information requested by the Company with respect to themselves and the proposed distribution by them as reasonably shall be necessary in order to assure compliance with federal and applicable state securities laws and to make the registration statement correct, accurate and complete in all respects with respect to such sellers; provided, however, that this requirement shall not be deemed to limit any disclosure obligation arising out of any seller's relationship to the Company if one of such seller's agents or affiliates is an officer, director or control person of the Company. In addition, the sellers shall, if requested by the Company, execute such other agreements, which are reasonably satisfactory to them and which shall contain such provisions as may be customary and reasonable in order to accomplish the registration of the Restricted Stock. In connection with each registration pursuant to Sections 2, 3 or 4 covering an underwritten public offering, the Company and each seller agree to enter into a written agreement with the managing underwriter selected in the manner herein provided in such form and containing such provisions as are customary in the securities business for such an arrangement between such underwriter and companies of the Company's size and investment stature. 6.

All expenses incurred by the Company in complying with Sections 2, 3 and 4, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or "BLUE SKY" laws, fees and expenses of one counsel for the selling holders of Restricted Stock in connection with the registration of Restricted Stock (which counsel shall be selected (i) by the Series A Purchasers selling Original Restricted Stock if such registration is made pursuant to clause (i) of subsection 2(a), (ii) by the Founders selling Original Restricted Stock if such registration is made pursuant to clause (ii) of subsection 2(a), and (iii) by the holders of at least 30% in interest of shares of Series B/C/D/E/F Restricted Stock if such registration is made pursuant to subsection 2(b); PROVIDED, HOWEVER, if both the Series A Purchasers and the Founders register shares of Original Restricted Stock pursuant to subsection 2(a), such counsel shall be selected by the Series A Purchasers, subject to approval by the Founders (which approval shall not be unreasonably withheld)), fees of the National Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents and registrars, costs of any insurance which might be obtained, but excluding any Selling Expenses, are called "REGISTRATION EXPENSES".

INDEMNIFICATION. (a) In the event of a registration of any of the Restricted Stock under the Securities Act pursuant to Sections 2, 3 or 4, the Company will indemnify and hold harmless each holder of Restricted Stock, its officers and directors, each underwriter of such Restricted Stock thereunder and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such holder, officer, director, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Restricted Stock was registered under the Securities Act pursuant to Sections 2, 3 or 4, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Restricted Stock under the securities laws thereof (any such application, document or information herein called a "BLUE SKY APPLICATION"), (iii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (iv) any violation by the Company or its agents of any rule or regulation promulgated under the Securities Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration, or (v) any failure to register or qualify the Restricted Stock in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company (the undertaking of any underwriter chosen by the Company being attributed to the Company) will undertake such registration or qualification on the seller's behalf (provided that in such instance the Company shall not be so liable if it has undertaken its best efforts to so register or qualify the Restricted Stock) and will reimburse each such holder, and such officer and director, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any such seller, any such underwriter or any such controlling person in writing specifically for use in such registration statement or prospectus. 12

13 (b) In the event of a registration of any of the Restricted Stock under the Securities Act pursuant to Sections 2, 3 or 4, each seller of such Restricted Stock thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of the Securities Act, each officer of the Company who signs the registration statement, each director of the Company, each other holder of Restricted Stock, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer, director, other seller, underwriter or, controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Restricted Stock was registered under the Securities Act pursuant to Sections 2, 3 or 4, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or any Blue Sky Application or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer, director, other seller, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, PROVIDED, HOWEVER, that such seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by such seller specifically for use in such registration statement or prospectus, and PROVIDED, FURTHER, HOWEVER, that the liability of each seller hereunder shall be limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the shares sold by such seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the proceeds received by such seller from the sale of Restricted Stock covered by such registration statement. (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 7 and shall only relieve it from any liability which it may have to such indemnified party under this Section 7 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 7 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of 13

14 investigation and of liaison with counsel so selected; PROVIDED, HOWEVER, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. (d) The indemnities provided in this Section 7 shall survive the transfer of any Restricted Stock by such holder. 8. CHANGES IN COMMON STOCK OR PREFERRED STOCK. If, and as often as, there is any change in the Common Stock or the Preferred Shares by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Common Stock or the Preferred Shares as so changed. 9. RULE 144 REPORTING. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Stock to the public without registration, at all times after 90 days after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act; (b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to each holder of Restricted Stock forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Restricted Stock without registration. 10.

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 to 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. To the extent that any other laws govern the matters as to which we are opining herein, we have assumed that such laws are identical to the state laws of The Commonwealth of Massachusetts, and we are expressing no opinion herein as to whether such assumption is reasonable or correct. 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."

Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan (i) to the extent that, immediately after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Subsidiary, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans of the Company and its subsidiaries accrues at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) worth of stock (determined at the fair market value of the shares at the time such option is granted) for each calendar year in which such option is outstanding at any time. 4. Offering Periods. The Plan shall be implemented by consecutive, overlapping Offering Periods with a new Offering Period commencing on the first Trading Day on or after June 1 and December 1 of each year, or on such other date as the Board shall determine, and continuing thereafter until terminated in accordance with Section 20 hereof; provided, however, that the first Offering Period under the Plan shall commence with the first Trading Day on or after -3-

4 the date on which the Securities and Exchange Commission declares the Company's Registration Statement effective and ending on the last Trading Day on or before May 31, 2000. The Board shall have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future offerings without stockholder approval if such change is announced at least five (5) days prior to the scheduled beginning of the first Offering Period to be affected thereafter. 5. Participation. a. An eligible Employee may become a participant in the Plan by completing a subscription agreement 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 decrease the rate of his or her payroll deductions to zero percent (0%) once during each Offering Period by completing or filing with the Company a new subscription agreement authorizing such change in payroll deduction 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. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's payroll deductions may be decreased to zero percent (0%) at any time during a Purchase Period.

5 e. 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 on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of the Company's Common Stock determined by dividing such Employee's payroll deductions accumulated prior to such Exercise Date and retained in the Participant's account as of the Exercise Date by the applicable Purchase Price; provided that in no event shall an Employee be permitted to purchase during each Purchase Period more than 5,000 shares of the Company's Common Stock (subject to any adjustment pursuant to Section 19), and provided further that such purchase shall be subject to the limitations set forth in Sections 3(b) and 12 hereof. 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, 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 -5-

6 time by giving written notice to the Company in the form of Exhibit A 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. 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 -6-

7 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. 17. User 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 -7-

8 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 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 -8-

9 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. -9-

10 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. -10-

2 STRATEGIC ALLIANCE AND MASTER SERVICES AGREEMENT This STRATEGIC ALLIANCE AND MASTER SERVICES AGREEMENT, consisting of the terms and conditions set forth below and the attached schedules, each of which is incorporated into and made a part hereof by this reference (the "Agreement"), is entered into by and between AKAMAI TECHNOLOGIES, INC., a Delaware corporation ("Akamai"), having its principal place of business as set forth on the cover page of this Agreement, and APPLE COMPUTER, INC., a California corporation ("Apple"), having its principal place of business as set forth on the cover page of this Agreement, effective as of April 1, 1999 (the "Effective Date"). BACKGROUND Akamai has developed proprietary technology to efficiently deliver content over the Internet, and is in the business of providing services including the distribution of such content. To support such services, Akamai has deployed a worldwide network dedicated to web content distribution. Apple owns and distributes QuickTime technology, which includes software and a format that facilitates the distribution of audio, video, sound, music, 3D, virtual reality and other multimedia content, including streaming media, over the Internet and other computer networks (today known as QuickTime 4 and with any later versions or releases, "QuickTime"). Part of Apple's QuickTime technology consists of software for playback of content in the QuickTime format (currently and with any later versions or releases, "QuickTime Player"). Apple is in the process of developing and deploying a service currently offered under the name "QuickTime TV" intended principally for transmitting over the Internet through computer networks owned or operated by or for Apple live streams of multimedia content in QuickTime format (today and as may be later renamed "QT-TV"). Akamai and Apple desire to enter into this Agreement whereby Apple and Akamai will work together to optimize the Akamai Network (as defined below) to make publicly available streaming media content in the QuickTime format over QT-TV and otherwise as provided in this Agreement to ensure that the optimal server will be chosen to deliver the best performance to customers/users of QT-TV and Apple Content. Akamai will provide to Apple certain web content distribution and network communications services to facilitate the deployment of QT-TV and the serving of streaming media content in the QuickTime format, all on the terms and subject to the conditions set forth below.

THIS NOTE MAY NOT BE SOLD, MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT OR THE AVAILABILITY OF AN EXEMPTION FROM THE REGISTRATION PROVISIONS UNDER SAID ACT OR STATE SECURITIES LAWS. No. ______ Akamai Technologies, Inc. 15% Senior Subordinated Note $____________ Cambridge, Massachusetts May 7, 1999 --------------------- Akamai Technologies, Inc., a Delaware corporation (the "Company"), for value received, hereby promises to pay to __________________ __________________, or registered assigns, the principal sum of ____________________ Dollars ($_________) on May 6, 2004 or such earlier date as provided herein (the "Maturity Date"), and to pay interest (computed on the basis of a 365-day year) from the date hereof on the unpaid balance of such principal amount from time to time outstanding at the rate of fifteen percent (15%) per annum. Such interest is to be compounded annually and added to the principal amount of the Note on May 6 of each year commencing May 6, 2000 and is due and payable on the Maturity Date. This Note is one of a series of the Company's Notes known as its 15% Senior Subordinated Notes (collectively referred to herein as the "Notes"), all of like tenor, except as to the date of issuance, identifying number and principal amount thereof. The Notes are limited in aggregate original principal amount to $15,000,000 and are issued or to be issued by the Company pursuant to the 15% Senior Subordinated Notes and Warrants to Purchase Common Stock Purchase Agreement dated May 7, 1999 among the Company, the original holder of this Note and other purchasers of Notes (collectively referred to herein as the "Purchase Agreement"), to which reference is made for a statement of certain additional rights and benefits to which the holder of this Note is entitled.

36 1. SUBORDINATION. (a) SUBORDINATION TO SENIOR INDEBTEDNESS. The indebtedness evidenced by this Note, and the payment of the principal hereof, and any interest hereon, is wholly subordinated, junior and subject in right of payment, to the extent and in the manner hereinafter provided, to the prior payment of all Senior Indebtedness of the Company now outstanding or hereinafter incurred. "Senior Indebtedness" means the principal of, and premium, if any, and interest on (i) all indebtedness of the Company for monies borrowed from banks, trust companies, insurance companies and other financial institutions, including commercial paper and accounts receivable sold or assigned by the Company to such institutions, (ii) obligations of the Company as lessee under leases of real or personal property, which obligations have been or should be, in accordance with generally accepted accounting principles, capitalized on the books of the lessee, (iii) principal of, and premium, if any, and interest on any indebtedness or obligations of others of the kinds described in (i) and (ii) above assumed or guaranteed in any manner by the Company, and (iv) deferrals, renewals, extensions and refundings of any such indebtedness or obligations described in (i), (ii) and (iii) above, unless such indebtedness, by its terms or the terms of the instrument creating or evidencing it, is subordinate or pari passu in right of payment to the Notes; PROVIDED that the aggregate principal amount of Senior Indebtedness shall not in any event exceed $15,000,000 at any time outstanding. Notwithstanding the foregoing, "Senior Indebtedness" shall not include indebtedness of the Company evidenced by the other Notes, which shall rank equally and ratably with this Note. (b) NO PAYMENT UPON PAYMENT DEFAULT OR ACCELERATION OF SENIOR INDEBTEDNESS. No payment on account of principal of or interest on the Notes shall be made, and no Notes shall be redeemed or purchased directly or indirectly by the Company (or any of its subsidiaries), if at the time of such payment or purchase or immediately after giving effect thereto, there shall exist or shall have occurred (i) any default by the Company in the payment of principal of or interest on any Senior Indebtedness (a "Payment Default") or (ii) an event of default (other than a Payment Default) with respect to any Senior Indebtedness with an outstanding amount of at least $1,000,000, as defined in the instrument under which the same is outstanding, permitting the holders thereof to accelerate the maturity thereof (a "Covenant Default"), which has resulted in the actual acceleration of such Senior Indebtedness; in each case, of which the holders of the Notes shall have been given written notice and such event of default or default shall not have been cured or waived or shall not have ceased to exist.

37 (c) RESTRICTIONS ON PAYMENT UPON COVENANT DEFAULT IN SENIOR INDEBTEDNESS. No payment on account of principal of or interest on the Notes shall be made, and no Notes shall be redeemed or purchased directly or indirectly by the Company (or any of its subsidiaries) during the period commencing with the date on which a holder of Senior Indebtedness gives written notice to the holders of the Notes of the occurrence of any Covenant Default and ending on the earlier of (i) the date which is 180 days after the commencement of such period, and (ii) the first date after the commencement of such period on which all such Covenant Defaults are cured or waived ("Payment Blockage Period"); PROVIDED that (x) the holders of Senior Indebtedness shall not be entitled to institute a Payment Blockage Period more often than once within any period of three hundred sixty (360) consecutive days and (y) no Covenant Default or event which, with the giving of notice and/or lapse of time, would become a Covenant Default which existed on the date of the commencement of any such Payment Blockage Period may be used as the basis for any subsequent payment blockage notice unless such Covenant Default or event, as the case may be, shall in the interim have been cured or waived for a period of not less than ninety (90) consecutive days. (d) PAYMENT UPON DISSOLUTION, ETC. (i) Any bankruptcy, insolvency, reorganization, receivership, composition, assignment for benefit of creditors or other similar proceeding initiated by or against the Company or any dissolution or winding up or total or partial liquidation or reorganization of the Company is hereinafter referred to as a "Proceeding". Upon payment or distribution to creditors in a Proceeding of assets of the Company of any kind or character, whether in cash, property or securities, all principal and interest (including any interest accruing after the commencement of the Proceeding, whether or not allowable), and any or all other amounts payable to the holders of Senior Indebtedness under the Senior Indebtedness, due upon any Senior Indebtedness shall first be paid in full, or payment thereof in full duly provided for, before any holders of the Notes shall be entitled to receive or, if received, to retain any payment or distribution on account of the Notes; and upon any such Proceeding, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which any holders of the Notes would be entitled except for the provisions of this Section 1 shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by any holders of the Notes who shall have received such payment or distribution, directly to the holders of the Senior Indebtedness (pro rata to each such holder on the basis of the respective amounts of such Senior Indebtedness held by such holder) or their representatives to the extent necessary to pay all such Senior Indebtedness in full after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to any holders of the Notes. In the event of any Proceeding, the holders of Notes shall be entitled to be paid one hundred percent (100%) of the principal amount thereof and accrued interest thereon (including any interest accruing after the commencement of the Proceeding, whether or not allowable), and any or all other amounts payable to the

38 holders of the Notes under the Notes, before any distribution of assets shall be made among the holders of debt subordinated to the Notes or any class of shares of the capital stock of the Company in their capacities as holders of such shares. (ii) The holders of the Notes also agree that they shall take all reasonable actions necessary to file and prove the full amount of all their claims in any Proceeding, and the holders of the Notes shall not expressly, by implication or by inaction waive any claim in any Proceeding without the written consent of such holders of Senior Indebtedness. (iii) For purposes of this Section 1(d), the words "assets" and "cash, property or securities" shall not be deemed to include shares of Common Stock of the Company as reorganized or readjusted, or securities of the Company or any other person provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Section 1 with respect to the Notes to the payment of all Senior Indebtedness which may at the time be outstanding, if (x) the Senior Indebtedness is assumed by the new person, if any, resulting from any such reorganization or readjustment, and (y) the rights of the holders of Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. (e) SUBROGATION. Subject to payment in full of all Senior Indebtedness, the holders of the Notes shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of the assets of the Company made on such Senior Indebtedness until all principal and interest on the Notes shall be paid in full; and for purposes of such subrogation, no payments or distributions to the holders of Senior Indebtedness of any cash, property or securities to which any holders of the Notes would be entitled except for the subordination provisions of this Section 1 shall, as between the holders of the Notes and the Company and/or its creditors other than the holders of the Senior Indebtedness, be deemed to be a payment on account of the Senior Indebtedness. (f) RIGHTS OF HOLDERS UNIMPAIRED. The provisions of this Section 1 are and are intended solely for the purposes of defining the relative rights of the holders of the Notes and the holders of Senior Indebtedness and nothing in this Section 1 shall impair, as between the Company and any holders of the Notes, the obligation of the Company, which is unconditional and absolute, to pay to the holders of the Notes the principal thereof and interest thereon, and any or all other amounts payable to the holders of the Notes under the Notes, in accordance with the terms of the Notes, nor shall anything herein prevent any holders of the Notes from exercising all remedies otherwise permitted by applicable law or hereunder upon default, subject to the rights set forth above of holders of Senior Indebtedness to receive cash, property or securities otherwise payable or deliverable to the holders of the Notes.

39 (g) HOLDERS OF SENIOR INDEBTEDNESS. These provisions regarding subordination will constitute a continuing offer to all persons who, in reliance upon such provisions, become holders of, or continue to hold, Senior Indebtedness; such provisions are made for the benefit of the holders of Senior Indebtedness, and such holders are hereby made obligees under such provisions to the same extent as if they were named therein, and they or any of them may proceed to enforce such subordination. The holder of this Note shall execute and deliver to any holder of Senior Indebtedness any such instrument as such holder of Senior Indebtedness may request in order to confirm the subordination of this Note to such Senior Indebtedness upon the terms set forth in this Note. 2. PREPAYMENT OF PRINCIPAL. Subject to the subordination provisions of Section 1, the principal indebtedness represented by this Note may be prepaid in whole or in part by the Company at any time without premium or penalty upon 10 days' prior written notice to the holder of this Note. Partial prepayments shall first be applied to accrued and unpaid interest, and then principal. Any prepayment shall be allocated among the Notes so that the amount prepaid with respect to the Notes is pro rata based upon the aggregate outstanding principal on the Notes. 3. EVENT OF DEFAULT. Subject to the subordination provisions of Section 1, in case an Event of Default, as defined in the Purchase Agreement shall occur and be continuing, the outstanding principal and interest of this Note, and any or all other amounts payable to the holders of the Notes under the Notes may be declared immediately due and payable in the manner and with the effect provided in the Purchase Agreement. 4. CERTAIN ADDITIONAL COVENANTS. The Company covenants to the holder of this Note that, so long as the Company has or may have any obligation under this Note: (a) It will comply in all material respects with all applicable laws and orders to which it may be subject, if failure so to comply would materially impair its ability to perform its obligations under this Note. (b) It will notify holder of this Note immediately upon the occurrence of an Event of Default or any event or action which constitutes or is likely to give rise to a Change of Control (as defined in the Purchase Agreement). (c) It will not use the proceeds of the Notes in any manner that would cause such borrowing or the application of such proceeds to violate any applicable law, rule or regulation. (d) This Note will rank pari passu with or senior to all other indebtedness of the Company which is not Senior Indebtedness.

40 5. NOTE REGISTER. (a) The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. (b) Each holder of a Note shall be deemed to have agreed by acceptance of such Note, not to transfer Notes except in minimum denominations of $500,000 (or if less with respect to any Note, the entire unpaid principal amount of such Note). (c) Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Note and of indemnity reasonably satisfactory to it, and upon reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of this Note (in case of mutilation) the Company will make and deliver in lieu of this Note a new Note of like tenor and unpaid principal amount and dated as of the date to which interest has been paid on the unpaid principal amount of this Note in lieu of which such new Note is made and delivered. 6. GENERAL. (a) SUCCESSORS AND ASSIGNS. This Note, and the obligations and rights of the Company hereunder, shall be binding upon and inure to the benefit of the Company, the holder of this Note, and their respective heirs, successors and assigns. (b) RECOURSE. Recourse under this Note shall be to the general assets of the Company only and in no event to the officers, directors or stockholders of the Company. (c) CHANGES. Changes in or additions to this Note may be made and compliance with any term, covenant, agreement, condition or provision set forth herein may be omitted or waived (either generally or in a particular instance and either retroactively or prospectively), upon written consent of the Company and the holders of at least 50% of the principal amount of the Notes then outstanding; PROVIDED, HOWEVER, that no change, addition, omission or waiver which causes any change in or extension of the time of payment of the principal amount or interest, or the reduction of the rate of interest on, or in any way affects or impairs the obligation of the Company in respect of the principal of or interest on, any Note, or causes any change in the provisions of Section 2 of any Note, or impairs or affects the right to institute suit for payment of the Note or causes any change in this Section 6(c), shall be made without the written consent of the holder of such Note.

41 (d) CURRENCY. All payments shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender therein for the payment of public and private debts. (e) NOTICES. All notices, requests, consents and demands shall be made in writing and shall be mailed postage prepaid, or delivered by hand, to the Company or to the holder hereof at their respective addresses in accordance with the notice provisions of the Purchase Agreement.

If any date that may at any time be specified in this Note as a date for the making of any payment of principal or interest under this Note shall fall on Saturday, Sunday or on a day which in Boston, Massachusetts shall be a legal holiday, then the date for the making of that payment shall be the next subsequent day which is not a Saturday, Sunday or legal holiday. (g) GOVERNING LAW. This Note shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the Commonwealth of Massachusetts.

(j) The Company may not assign any of its rights or delegate any of its obligations under this Note (or any part thereof) without the prior written consent of the holder of this Note. (k) The Company hereby waives diligence, presentment, protest, demand, and notice of every kind other than notices expressly provided herein or by the Purchase Agreement or required by applicable law and, to the full extent permitted by law, the right to plead any statute of limitations as a defense to any demand hereunder.

43 EXHIBIT B FORM OF WARRANT THIS WARRANT IS NON-TRANSFERRABLE. THE SHARES OF COMMON STOCK ISSUED UPON EXERCISE OF THIS WARRANT ARE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN SECTION 4 OF THIS WARRANT. ----------------------------------------------- Warrant No. ___ Number of Shares: _________ (subject to adjustment) Date of Issuance: May 7, 1999 AKAMAI TECHNOLOGIES, INC. COMMON STOCK PURCHASE WARRANT (Void after May 7, 2004) Akamai Technologies, Inc., a Delaware corporation (the "Company"), for value received, hereby certifies that ________________________________, or its registered assigns (the "Registered Holder"), is entitled, subject to the terms set forth below, to purchase from the Company, at any time or from time to time on or after the date of issuance and on or before May 7, 2004 at not later than 5:00 p.m. (Boston, Massachusetts time), ______ shares of Common Stock, $0.01 par value per share, of the Company, at a purchase price of $14.979 per share. The shares purchasable upon exercise of this Warrant, and the purchase price per share, each as adjusted from time to time pursuant to the provisions of this Warrant, are hereinafter referred to as the "Warrant Shares" and the "Purchase Price," respectively. 1. EXERCISE. (a) This Warrant may be exercised by the Registered Holder, in whole or in part, by surrendering this Warrant, with the purchase form appended hereto as EXHIBIT I duly executed by such Registered Holder or by such Registered Holder's duly authorized attorney, at the principal office of the Company, or at such other office or agency as the Company may

44 designate, accompanied by payment in full, in lawful money of the United States, of the Purchase Price payable in respect of the number of Warrant Shares purchased upon such exercise; PROVIDED, HOWEVER, that this Warrant may not be exercised unless such exercise and the issuance of the Warrant Shares pursuant thereto shall comply with all applicable federal and state securities laws. (b) The Registered Holder may, at its option, elect to pay some or all of the Purchase Price payable upon an exercise of this Warrant by cancelling a portion of this Warrant exercisable for such number of Warrant Shares as is determined by dividing (i) the total Purchase Price payable in respect of the number of Warrant Shares being purchased upon such exercise by (ii) the excess of the Fair Market Value per share of Common Stock as of the effective date of exercise, as determined pursuant to subsection 1(c) below (the "Exercise Date") over the Purchase Price per share. If the Registered Holder wishes to exercise this Warrant pursuant to this method of payment with respect to the maximum number of Warrant Shares purchasable pursuant to this method, then the number of Warrant Shares so purchasable shall be equal to the total number of Warrant Shares, minus the product obtained by multiplying (x) the total number of Warrant Shares by (y) a fraction, the numerator of which shall be the Purchase Price per share and the denominator of which shall be the Fair Market Value per share of Common Stock as of the Exercise Date. The Fair Market Value per share of Common Stock shall be determined as follows: (i) If the Common Stock is listed on a national securities exchange, the NASDAQ National Market System, the NASDAQ system, or another nationally recognized exchange or trading system as of the Exercise Date, the Fair Market Value per share of Common Stock shall be deemed to be the last reported sale price per share of Common Stock thereon on the Exercise Date; or, if no such price is reported on such date, such price on the next preceding business day (provided that if no such price is reported on the next preceding business day, the Fair Market Value per share of Common Stock shall be determined pursuant to clause (ii)). (ii) If the Common Stock is not listed on a national securities exchange, the NASDAQ National Market System, the NASDAQ system or another nationally recognized exchange or trading system as of the Exercise Date, the Fair Market Value per share of Common Stock shall be deemed to be the amount most recently determined by the Board of Directors to represent the fair market value per share of the Common Stock (including without limitation a determination for purposes of granting Common Stock options or issuing Common Stock under an employee benefit plan of the Company); and, upon request of the Registered Holder, the Board of Directors (or a representative thereof) shall promptly notify the Registered Holder of the Fair Market Value per share of Common Stock. In the event this Warrant is being exercised in connection with a merger, sale or other transaction in which consideration is payable to the holders of Common Stock, then the Fair Market Value per share of Common Stock shall be the per share value of such consideration payable to such holders, as determined in good faith by the Board of Directors. Notwithstanding the foregoing, if the Board of Directors has not made such a determination within the three-month period prior to the Exercise Date, then (A) the Fair Market Value per share of Common Stock shall be the amount next determined by the Board of Directors to represent the fair market value per share of the Common Stock (including without limitation a determination for purposes of granting Common Stock options or issuing Common Stock under an employee benefit plan of the

45 Company), (B) the Board of Directors shall make such a determination within 15 days of a request by the Registered Holder that it do so, and (C) the exercise of this Warrant pursuant to this subsection 1(b) shall be delayed until such determination is made. (c) Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this Warrant shall have been surrendered to the Company as provided in subsection 1(a) above. At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in subsection 1(d) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates. (d) As soon as practicable after the exercise of this Warrant in full or in part, and in any event within 10 days thereafter, the Company, at its expense, will cause to be issued in the name of, and delivered to, the Registered Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct: (i) a certificate or certificates for the number of full Warrant Shares to which such Registered Holder shall be entitled upon such exercise plus, in lieu of any fractional share to which such Registered Holder would otherwise be entitled, cash in an amount determined pursuant to Section 3 hereof; and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the sum of (a) the number of such shares purchased by the Registered Holder upon such exercise plus (b) the number of Warrant Shares (if any) covered by the portion of this Warrant cancelled in payment of the Purchase Price payable upon such exercise pursuant to subsection 1(b) above. 2. ADJUSTMENTS. (a) If outstanding shares of the Company's Common Stock shall be subdivided into a greater number of shares or a dividend in Common Stock shall be paid in respect of Common Stock, the Purchase Price in effect immediately prior to such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Common Stock shall be combined into a smaller number of shares, the Purchase Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made in the Purchase Price, the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (b) If there shall occur any capital reorganization or reclassification of the Company's Common Stock (other than a change in par value or a subdivision or combination as provided for in subsection 2(a) above), or any consolidation or merger of the Company with

46 or into another corporation, or a transfer of all or substantially all of the assets of the Company, then, as part of any such reorganization, reclassification, consolidation, merger or sale, as the case may be, lawful provision shall be made so that the Registered Holder of this Warrant shall have the right thereafter to receive upon the exercise hereof the kind and amount of shares of stock or other securities or property which such Registered Holder would have been entitled to receive if, immediately prior to any such reorganization, reclassification, consolidation, merger or sale, as the case may be, such Registered Holder had held the number of shares of Common Stock which were then purchasable upon the exercise of this Warrant. In any such case, appropriate adjustment (as reasonably determined in good faith by the Board of Directors of the Company) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder of this Warrant, such that the provisions set forth in this Section 2 (including provisions with respect to adjustment of the Purchase Price) shall thereafter be applicable, as nearly as is reasonably practicable, in relation to any shares of stock or other securities or property thereafter deliverable upon the exercise of this Warrant. (c) When any adjustment is required to be made in the Purchase Price, the Company shall promptly mail to the Registered Holder a certificate setting forth the Purchase Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Such certificate shall also set forth the kind and amount of stock or other securities or property into which this Warrant shall be exercisable following the occurrence of any of the events specified in subsection 2(a) or (b) above. 3. FRACTIONAL SHARES. The Company shall not be required upon the exercise of this Warrant to issue any fractional shares, but shall make an adjustment therefor in cash on the basis of the fair market value per share of Common Stock, as determined in good faith by the Board of Directors of the Company. 4. REQUIREMENTS FOR TRANSFER. (a) This Warrant and the Warrant Shares may be sold or transferred to any person who, immediately after the sale or transfer, holds or will hold (i) in the case of a sale or transfer of this Warrant, a portion of this Warrant covering at least 10,000 Warrant Shares, and (ii) in the case of a sale or transfer of Warrant Shares, at least 10,000 Warrant Shares. Notwithstanding the foregoing, this Warrant and the Warrant Shares may not be sold or transferred unless either (i) they first shall have been registered under the Securities Act of 1933, as amended (the "Act"), or (ii) if requested by the Company, the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Act. (b) Notwithstanding the foregoing, no registration or opinion of counsel shall be required for a sale or transfer made in accordance with Rule 144 under the Act. (c) Each certificate representing Warrant Shares shall bear a legend substantially in the following form: "The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may

47 not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such securities are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required." The foregoing legend shall be removed from the certificates representing any Warrant Shares, at the request of the holder thereof, at such time as they become eligible for resale pursuant to Rule 144(k) under the Act. 5. RESERVATION OF STOCK. The Company will at all times reserve and keep available, solely for issuance and delivery upon the exercise of this Warrant, such number of Warrant Shares and other stock, securities and property, as from time to time shall be issuable upon the exercise of this Warrant. 6. REGISTRATION RIGHTS. The Registered Holder and the holder of Warrant Shares issued upon exercise of this Warrant shall have the same rights and obligations with respect to registration under the Act and with respect to indemnification in connection with any such registration as if (i) such Registered Holder or holder were one of the Series B Purchasers under that certain Amended and Restated Registration Rights Agreement dated as of April 16, 1999 among the Company and the individuals and entities named therein (the "Registration Rights Agreement") and (ii) the Warrant Shares were Series B Conversion Shares under the Registration Rights Agreement.

The Maker agrees to pay on demand all costs of collection, including reasonable attorneys' fees, incurred by the holder in enforcing the obligations of the Maker under this Note. No delay or omission on the part of the holder in exercising any right under this Note shall operate as a waiver of such right or of any other right of such holder, nor shall any delay, omission or waiver on any one occasion be deemed a bar to or waiver of the same or any other right on any future occasion.

5 AKAMAI TECHNOLOGIES, INC. 201 Broadway Cambridge, Massachusetts 02139 As of September 20, 1999 TO: Microsoft Corporation Re: SERIES F CONVERTIBLE PREFERRED STOCK Ladies and Gentlemen: Akamai Technologies, Inc., a Delaware corporation (the "COMPANY"), agrees with you as follows: ARTICLE I PURCHASE, SALE AND TERMS OF SHARES 1.01 THE PREFERRED SHARES. The Company has authorized the issuance and sale of up to 985,545 shares of its previously authorized but unissued shares of Series F Convertible Preferred Stock, par value $.01 per share (the "SERIES F PREFERRED STOCK"), at a purchase price of $15.22 per share to Microsoft Corporation. (the "PURCHASER"). The designation, rights, preferences and other terms and conditions relating to the Series F Preferred Stock are as set forth on EXHIBIT 1.01 hereto. The Series F Preferred Stock is sometimes referred to herein as the "PREFERRED SHARES." 1.02 THE CONVERTED SHARES. The Company has authorized and has reserved and covenants to continue to reserve, free of preemptive rights and other preferential rights, a sufficient number of its previously authorized but unissued shares of Common Stock to satisfy the rights of conversion of the holders of the Preferred Shares. Any shares of Common Stock issuable upon conversion of the Preferred Shares, and such shares when issued, are herein referred to as the "CONVERTED SHARES." 1.03 THE SHARES. The Preferred Shares and the Converted Shares are sometimes collectively referred to herein as the "SHARES." 1.04 PURCHASE PRICE AND CLOSING. The Company agrees to issue and sell to the Purchaser and, subject to and in reliance upon the representations, warranties, covenants, terms and conditions of this Agreement, the Purchaser agrees to purchase 985,545 shares of Series F Preferred Stock for an aggregate purchase price of $14,999,994.90. The purchase and sale shall take place at a closing (the "CLOSING") to be held on or before September 20, 1999, at 10:00 A.M., at such location and at such time as may be mutually agreed upon, subject to the satisfaction of all of the conditions to the Closing specified in Article II herein. At the Closing the Company will issue and deliver certificates evidencing the shares of Series F Preferred 1

6 Stock to be sold at the Closing to the Purchaser (or its nominee) against payment of the full purchase price therefor by (i) wire transfer of immediately available funds to an account designated by the Company, (ii) check payable to the order of the Company or its designee, or (iii) any combination of (i) and (ii) above. 1.05 RESTRICTIONS ON TRANSFER AND STANDSTILL AGREEMENT. (a) TRANSFER RESTRICTIONS. Without the prior written permission of the Company, no more than 25% of the Shares may be sold or transferred by the Purchaser (except to a wholly-owned subsidiary or a wholly-owned subsidiary of a wholly-owned subsidiary of the Purchaser, or the like); provided, however, that if the Purchaser wishes to sell or transfer any of such 25% of the Shares to a third party, it shall first submit a written offer to sell such Shares to the Company on terms and conditions, including price, not less favorable to the Company than those on which it proposes to sell such Shares to such third party (the "OFFER"), PROVIDED, HOWEVER, nothing in the foregoing shall restrict the Purchaser from entering into a bonafide transaction with a nationally recognized investment banking firm which constitutes a hedge against changes in the market price of the Company's Common Stock. The Offer shall disclose the identity of the proposed purchaser or transferee, the Shares proposed to be sold or transferred and the agreed terms of the sale or transfer. If the Offer provides that the purchase price for the Shares shall be paid other than in cash, then the per-Share purchase price for the Shares subject to the Offer shall be deemed to be the Market Price (as defined below). Within five days after receipt of the Offer, the Company shall give written notice to the Purchaser of its intent to purchase all or none of the offered Shares on the same terms and conditions as set forth in the Offer. The Company can pay the cash equivalent of any non-cash consideration based on the Market Price. If the Company does not purchase all of the Shares offered by the Purchaser pursuant to the Offer, such Shares may be sold by the Purchaser at any time within 90 days after the date of the Offer at not less than the price and upon other terms and conditions, if any, not more favorable to such proposed purchaser or transferee than those specified in the Offer. All restrictions set forth in this Section 1.05(a) shall terminate upon the earlier of the date one year after the date of (i) closing of a Qualified Public Offering (as defined in Section 5.01 of the Agreement) or (ii) registration of a class of the Company's securities under the Securities Exchange Act of 1934, as amended (the "1934 ACT"). For purposes of this Section 1.05(a), the "MARKET PRICE" shall be determined as follows: (i) If the Company's Common Stock is listed on a national securities exchange, the NASDAQ National Market System, the NASDAQ system, or another nationally recognized exchange or trading system (an "EXCHANGE") as of the date of the Offer, then the Market Price shall be deemed to be the average closing price per share of the Company's Common Stock on such Exchange for the 20 trading days ending on the trading day prior to the date of the Offer; provided that if the Company's Common Stock has been listed on an Exchange for fewer than 21 trading days, the Market Price shall be deemed to be the average closing price per share of the Company's Common Stock since it has been listed on such Exchange. (ii) If the Company's Common Stock is not listed on an Exchange as of the date of the Offer, then the Market Price shall be the fair market value per share of the Shares as of the date of the Offer as determined in good faith by the Purchaser's Board of Directors; provided, however, that the Company shall have the right to contest such 2

7 determination by giving notice thereof to the Purchaser within ten days of such determination, and in such event the Market Price shall be the fair market value per share of the Shares as of the date of the Offer as determined by an independent appraiser to be selected by the Purchaser and approved by the Company, which approval shall not be unreasonably withheld. The independent appraiser's fees and expenses shall be paid as follows: (A) If the Market Price as determined by the independent appraiser is less than or equal to 110% of the Market Price determined by the Purchaser's Board of Directors, then the independent appraiser's fees and expenses shall be paid by the Company. (B) If the Market Price as determined by the independent appraiser is greater than 110% of the Market Price determined by the Purchaser's Board of Directors, then the independent appraiser's fees and expenses shall be paid by the Purchaser. (b) STANDSTILL AGREEMENT. The Purchaser hereby agrees that from and after the date hereof until the earlier of the date one year after the date of (i) closing of a Qualified Public Offering (as defined in Section 5.01 of this Agreement) or (ii) registration of a class of the Company's securities under the 1934 Act, unless such shall have been specifically invited in writing by the Company, neither Purchaser nor any of its affiliates (as such term is defined under the 1934 Act) or agents will in any manner, directly or indirectly, (a) effect or seek, offer or propose (whether publicly or otherwise) to effect, or cause or participate in or in any way assist any other Person to effect or seek, offer or propose (whether publicly or otherwise) to effect or participate in, (i) any acquisition of any securities (or beneficial ownership thereof) or assets of the Company, except that during the one-year period from and after a Qualified Public Offering, the Purchaser may acquire capital stock of the Company provided that after any such acquisition, the Purchaser and its affiliates shall beneficially own no more than 10% of each class of the Company's voting securities; (ii) any tender or exchange offer, merger or other business combination involving the Company; (iii) any recapitalization, restructuring, liquidation, dissolution or other extraordinary transaction with respect to the Company; or (iv) any "solicitation" of "proxies" (as such terms are used in the proxy rules of the Commission) or consents to vote any voting securities of the Company; (b) otherwise act, alone or in concert with others, to seek control of the Company's Board of Directors; or (c) take any action which might require the Company to make a public announcement regarding any of the types of matters set forth in (a) above. Notwithstanding the above in this Section 1.05(b), if (i) following the Company's initial public offering a bona fide tender offer that seeks to acquire more than 50% of the outstanding voting securities of the Company is commenced by a third party unaffiliated with the Purchaser, or (ii) prior to the Company's initial public offering any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the 1934 Act) other than the Purchaser and its affiliates acquires more than 50% of the Company's outstanding voting securities, then any above restriction contained in this Section 1.05(b) imposed on the Purchaser will immediately terminate, and the Purchaser shall be free to acquire or offer to acquire any or all outstanding shares of the Company. Prior to the Company's initial public offering, the Company will provide written notice to the Purchaser immediately after the Company learns of any such individual, entity or group acquiring more than 25% of the Company's outstanding voting securities. Notwithstanding anything to the contrary in this Section, the Purchaser shall be entitled to acquire securities of the Company 3

8 pursuant to Section 4.1 of the Amended and Restated Stockholders' Agreement (as defined in Section 2.03(b) below). (c) "MOST FAVORED NATION" If (i) the Company sells securities to a Strategic Investor (as defined in Section 4.6(l) of the Amended and Restated Stockholders' Agreement) and (ii) in connection with its purchase of such securities, such Strategic Investor is subject to provisions less restrictive than those set forth in Sections 1.05(a) or 1.05(b) above to purchase and/or sell securities of the Company, then the Company shall amend such sections, and/or take such other actions as may be required (including releasing restrictions imposed by Sections 1.05(a) or 1.05(b)), in order that the Purchaser obtains rights no less favorable than those obtained by such Strategic Investor to purchase and/or sell securities of the Company. 1.06 USE OF PROCEEDS. The Company shall use the proceeds from the sale of the Preferred Shares under this Agreement for working capital and general corporate purposes. 1.07 Representations and Warranties by the Purchaser.
