As used herein, "CMGI," "we" or "us" refers topart of your investment. RISKS PARTICULAR TO CMGI Inc. and its consolidated subsidiaries. CMGIWE MAY NOT HAVE OPERATING INCOME OR NET INCOME IN THE FUTURE. During the fiscal year ended July 31, 1999 CMGIand for the nine months ended April 30, 2000, we had an operating loss of approximately $127 million and net income of approximately $475 million. CMGI may not have$1.4 billion, respectively. We anticipate continuing to incur significant operating income or net incomeexpenses in the future. If CMGI continuesfuture, including significant costs of revenues and selling, general and administrative and amortization expenses. As a result, we expect to havecontinue to incur operating losses CMGIand may not have enough money to expand itsgrow our business in the future. CMGIWe cannot assure you that we will achieve profitability or be capable of sustaining profitable operations. WE MAY HAVE PROBLEMS RAISING MONEY IT NEEDSWE NEED IN THE FUTURE. In recent years, CMGI haswe have financed itsour operating losses in part with profits from selling some of the stock of companies in which itwe had invested.invested through our @Ventures funds. This funding source may not be sufficient in the future, and CMGIwe may need to obtain funding from outside sources. However, CMGIwe may not be able to obtain funding from outside sources. In addition, even if CMGI findswe find outside funding sources, CMGIwe may be required to issue to such outside sources securities with greater rights than thatthose currently possessed by holders of shares of our common stock. CMGIWe may also be required to take other actions, which may lessen the value of our common stock, including borrowing money on terms that are not favorable to CMGI. CMGI'S SUCCESS DEPENDS GREATLY ON INCREASED USE OF THE INTERNET BY BUSINESS AND INDIVIDUALS. CMGI's success depends greatly on increased use of the Internet for advertising, marketing, providing services, and conducting business. Commercial use of the Internet is currently at an early stage of development and the future of the Internet is not clear. In addition, it is not clear how effective advertising on the Internet is in generating business as compared to more traditional types of advertising such as print, television, and radio. Because a significant portion of CMGI's business depends on CMGI's Internet operating company subsidiaries, CMGI's business will suffer if commercial use of the Internet fails to grow in the future. CMGIus. WE MAY INCUR SIGNIFICANT COSTS TO AVOID INVESTMENT COMPANY STATUS AND MAY SUFFER ADVERSE CONSEQUENCES IF DEEMED TO BE AN INVESTMENT COMPANY. CMGIWe may incur significant costs to avoid investment company status and may suffer other adverse consequences if deemed to be an investment company under the Investment Company Act of 1940. Some of our equity investments in other businesses made by CMGI and itsour venture subsidiaries may constitute investment securities under the 1940Investment Company Act. A company may be deemed to be an investment company if it owns investment securities with a value exceeding 40% of its total assets, subject to certain exclusions. Investment companies are subject to registration under, and compliance with, the 1940Investment Company Act unless a particular exclusion or Commission safe harbor provision applies. If CMGIwe were to be deemed an investment company, itwe would become subject to the requirements of the 1940Investment Company Act. As a consequence, CMGIwe would be prohibited from engaging in business or issuing itsour securities as it haswe have in the past and might be subject to civil and criminal penalties for noncompliance. In addition, certain of CMGI'sour contracts might be voidable, and a court-appointed receiver could take control of CMGIus and liquidate itsour business. Although CMGI'sour investment securities currently comprise less than 40% of itsour total assets, fluctuations in the value of these securities or of CMGI'sour other assets may cause this limit to be exceeded. ThisUnless an exclusion or safe harbor was available to us, we would require CMGIhave to attempt to reduce itsour investment securities as a percentage of itsour total assets. This reduction can be attempted in a number of ways, including the disposition of investment securities and the acquisition of non-investment security assets. If CMGI sellswe were required to sell investment securities, itwe may sell them sooner than itwe otherwise would. These sales may be at depressed prices and CMGIwe may never realize anticipated benefits from, or may incur losses on, these investments. SomeWe may be unable to sell some investments may not be sold due to contractual or legal restrictions or the inability to locate a suitable buyer. Moreover, CMGIwe may incur tax liabilities when it sellswe sell assets. CMGIWe may also be unable to purchase additional investment securities that may be important to itsour operating strategy. If CMGI decideswe decide to acquire non-investment security assets, itwe may not be able to identify and acquire suitable assets and businesses. CMGI DEPENDSbusinesses or the terms on which we are able to acquire such assets may be unfavorable. WE DEPEND ON CERTAIN IMPORTANT EMPLOYEES, AND THE LOSS OF ANY OF THOSE EMPLOYEES MAY HARM CMGI'SOUR BUSINESS. CMGI'sOur performance is substantially dependent on the performance of itsour executive officers and other key employees, in particular, David S. Wetherell, itsour chairman, president and chief executive officer, Andrew J. Hajducky III, itsour executive vice president, chief financial officer and treasurer, and David Andonian, itsour president, of corporate development. The familiarity of these individuals with the Internet industry makes them especially critical to CMGI'sour success. In addition, CMGI'sour success is dependent on itsour ability to attract, train, retain and motivate high quality personnel, especially for itsour management team. The loss of the services of any of CMGI'sour executive officers or key employees may harm itsour business. CMGI'sOur success also depends on itsour continuing ability to attract, train, retain and motivate other highly qualified technical and managerial personnel. Competition for such personnel is intense. THERE MAY BE CONFLICTS OF INTEREST AMONG OUR NETWORK COMPANIES, OUR OFFICERS, DIRECTORS AND STOCKHOLDERS AND US. Some of our officers and directors also serve as officers or directors of one or more of our network companies. As a result we, our officers and directors, and our network companies may face potential conflicts of interest with each other and with our stockholders. Specifically, our officers and directors may be presented with situations in their capacity as officers or directors of one of our network companies that conflict with their fiduciary obligations as officers or directors of our company or of another network company. IN FISCAL 1999 CMGI'S REVENUE DEPENDED IN LARGE PART ONAND THE FIRST NINE MONTHS OF FISCAL 2000, WE DERIVED A SINGLE CUSTOMERSIGNIFICANT PORTION OF OUR REVENUES FROM A SMALL NUMBER OF CUSTOMERS AND THE LOSS OF THAT CUSTOMERANY OF THOSE CUSTOMERS COULD SIGNIFICANTLY DAMAGE CMGI'SOUR BUSINESS. During the fiscal year ended July 31, 1999, CMGI derived a significant portion of its revenues from a small number of customers. During the fiscal year ended July 31, 1999, sales to CMGI's largest customer, Cisco Systems, Inc., accounted for 36% of CMGI'sour total revenues and 47% of CMGI'sour revenues from itsour fulfillment services business. CMGI believessegment. During the nine months ended April 30, 2000, sales to Cisco accounted for 13.4% of our total revenues and 56.4% of our revenues from our fulfillment services segment. We currently do not have any agreements with Cisco which obligate this customer to buy a minimum amount of products from us or to designate us as its sole supplier of any particular products or services. During the nine months ended April 30, 2000, approximately 16.5% of our total revenues and 21% of revenues from our Internet segment were derived from customer advertising contracts serviced by DoubleClick, Inc. We believe that itwe will continue to derive a significant portion of itsour operating revenuesrevenue from sales to a small number of customers. CMGI currently does notOUR STRATEGY OF SELLING ASSETS OF OR INVESTMENTS IN THE COMPANIES THAT WE HAVE ACQUIRED AND DEVELOPED PRESENTS RISKS. One element of our business plan involves raising cash for working capital for our Internet business by selling, in public or private offerings, some of the companies, or portions of the companies, that we have any agreements with Cisco which obligate Ciscoacquired and developed. Market and other conditions largely beyond our control affect: o our ability to buy a minimumengage in such sales; o the timing of such sales; and o the amount of productsproceeds from CMGIsuch sales. As a result, we may not be able to sell some of these assets. In addition, even if we are able to sell, we may not be able to sell at favorable prices. If we are unable to sell these assets at favorable prices, our business will be harmed. OUR STOCK PRICE MAY FLUCTUATE BECAUSE THE VALUE OF SOME OF OUR COMPANIES FLUCTUATES. A portion of our assets include the equity securities of both publicly traded and non-publicly traded companies. For example, we, directly or through our @Ventures funds, own a significant number of shares of common stock of Critical Path, Engage, Hollywood Entertainment, Kana Communications, Lycos, Marketing Services Group, MotherNature.com, NaviSite, Netcentives, Pacific Century CyberWorks, Primedia, Ventro and Vicinity, which are publicly traded companies. The market price and valuations of the securities that we hold in these and other companies may fluctuate due to designate CMGI as their sole suppliermarket conditions and other conditions over which we have no control. Fluctuations in the market price and valuations of any particular products or services. CMGI'Sthe securities that we hold in other companies may result in fluctuations of the market price of our common stock and may reduce the amount of working capital available to us. OUR STRATEGY OF EXPANDING ITSOUR BUSINESS THROUGH ACQUISITIONS OF OTHER BUSINESSES AND TECHNOLOGIES PRESENTS SPECIAL RISKS. CMGI intendsWe intend to continue to expand through the acquisition of businesses, technologies, products and services from other businesses. Acquisitions involve a number of special problems, including: o difficulty integrating acquired technologies, operations, and personnel with theour existing business;businesses; o diversion of management attention in connection with both negotiating the acquisitions and integrating the assets; o strain on managerial and operational resources as management tries to oversee larger operations; o exposure to unforeseen liabilities of acquired companies; o potential issuance of securities in connection with thean acquisition which securities lessenwith rights that are superior to the rights of holders of CMGI'sour currently outstanding securities; o the need to incur additional debt; and o the requirement to record potentially significant additional future operating costs for the amortization of goodwill and other intangible assets, which amounts could be significant. CMGIassets. We may not be able to successfully address these problems. Moreover, CMGI'sour future operating results will depend to a significant degree on itsour ability to successfully manage growth and integrate acquisitions. In addition, many of CMGI'sour investments are in early-stage companies with limited operating histories and limited or no revenues. CMGIWe may not be able to successfully develop these young companies. GROWING CONCERNS ABOUT THE USEWE FACE COMPETITION FROM OTHER ACQUIRORS OF "COOKIES"AND INVESTORS IN INTERNET-RELATED VENTURES WHICH MAY LIMIT OUR ABILITY TO DEVELOP USER PROFILES. Web sites typically place small filesPREVENT US FROM REALIZING STRATEGIC OPPORTUNITIES. Although we create many of information commonly known as "cookies" on a user's hard drive, generally without the user's knowledgeour network companies ourselves, we also acquire or consent. Cookie information is passedinvest in existing companies that we believe are complementary to the Web site through the Internet user's browser software. Our technology currently uses cookies to collect information about an Internet user's movement throughour network and further our vision of the Internet. Most currently availableIn pursuing these opportunities, we face competition from other capital providers and incubators of Internet-related companies, including publicly-traded Internet browsers allow userscompanies, venture capital companies and large corporations. Some of these competitors have greater financial resources than we do. This competition may limit our opportunity to modify their browser settings to prevent cookies from being stored on their hard drive, and a small minority of users are currently choosing to do so. Users can also delete cookies from their hard drive at any time. Some Internet commentators, privacy advocates and governmental bodies have suggested limiting or eliminating the use of cookies. The effectiveness ofacquire interests in companies that could advance our technology could be limited by any reduction or limitation in the use of cookies. If the use or effectiveness of cookies is limited, we would likely have to switch to other technology that allows us to gather demographic and behavioral information. This could require significant reengineering time and resources, might not be completed in time to avoid negative consequences to our business, financial condition or results of operations, and might not be possible at all. IF THE UNITED STATES OR OTHER GOVERNMENTS REGULATE THE INTERNET MORE CLOSELY, CMGI'S BUSINESS MAY BE HARMED. Because of the Internet's popularity and increasing use, new laws and regulations may be adopted. These laws and regulations may cover issues such as privacy, pricing and content. The enactment of any additional laws or regulations may impede the growthvision of the Internet and CMGI's Internet-related business and could place additional financial burdens on CMGI's business. TO SUCCEED, CMGI MUST RESPOND TO THE RAPID CHANGES IN TECHNOLOGY AND DISTRIBUTION CHANNELS RELATED TO THE INTERNET. The markets for CMGI's Internet products and services are characterized by: o rapidly changing technology; o evolving industry standards; o frequent new product and service introductions; o shifting distribution channels; and o changing customer demands. CMGI's success will depend on its ability to adapt to this rapidly evolving marketplace. CMGI may not be able to adequately adapt its products and services or to acquire new products and services that can compete successfully. In addition, CMGI may not be able to establish and maintain effective distribution channels. CMGI IS SUBJECT TO INTENSE COMPETITION. The market for Internet products and services is highly competitive. Moreover, the market for Internet products and services lacks significant barriers to entry, enabling new businesses to enter this market relatively easily. Competition in the market for Internet products and services may intensify in the future. Numerous well-established companies and smaller entrepreneurial companies are focusing significant resources on developing and marketing products and services that will compete with CMGI's products and services. In addition, many of CMGI's current and potential competitors have greater financial, technical, operational, and marketing resources. CMGI may not be able to compete successfully against these competitors in selling its goods and services. Competitive pressures may also force prices for Internet goods and services down and such price reductions may reduce CMGI's revenues. CMGI'S STRATEGY OF SELLING ASSETS OF OR INVESTMENTS IN THE COMPANIES THAT CMGI HAS ACQUIRED AND DEVELOPED PRESENTS RISKS. A significant element of CMGI's business plan involves selling, in public or private offerings, the companies, or portions of the companies, that it has acquired and developed. Market and other conditions largely beyond CMGI's control affect: o CMGI's ability to engage in such sales; o the timing of such sales; and o the amount of proceeds from such sales. As a result, CMGI may not be able to sell some of these assets. In addition, even if CMGI is able to sell, it may not be able to sell at favorable prices. If CMGI is unable to sell these assets at favorable prices, its business will be harmed. THE VALUE OF CMGI'S BUSINESS MAY FLUCTUATE BECAUSE THE VALUE OF SOME OF ITS ASSETS FLUCTUATES. A portion of CMGI's assets include the equity securities of both publicly traded and non-publicly traded companies. In particular, CMGI owns a significant number of shares of common stock of Engage Technologies, Inc., NaviSite, Inc., Lycos, Inc., Yahoo!, Hollywood Entertainment Corporation, Chemdex Corporation, Silknet Software, Inc. and Critical Path, Inc., which are publicly traded companies. The market price and valuations of the securities that CMGI holds in these and other companies may fluctuate due to market conditions and other conditions over which CMGI has no control. Fluctuations in the market price and valuations of the securities that CMGI's holds in other companies may result in fluctuations of the market price of CMGI's common stock and may reduce the amount of working capital available to CMGI. CMGI'Sincrease our value. OUR GROWTH PLACES STRAINSSTRAIN ON ITSOUR MANAGERIAL, OPERATIONAL AND FINANCIAL RESOURCES. CMGI'sOur rapid growth has placed, and is expected to continue to place, a significant strain on itsour managerial, operational and financial resources. Further, as the number of CMGI'sour users, advertisers and other business partners grows, CMGIwe will be required to manage multiple relationships with various customers, strategic partners and other third parties. FurtherOur further growth of CMGI or an increase in the number of itsour strategic relationships will increase this strain on CMGI'sour managerial, operational and financial resources, inhibiting CMGI'sour ability to achieve the rapid execution necessary to successfully implement itsour business plan. In addition, CMGI's future success will also depend on its ability to expand its sales and marketing organization and its support organization commensurate with the growth of CMGI's business and the Internet. CMGIWE MUST DEVELOP AND MAINTAIN POSITIVE BRAND NAME AWARENESS. CMGI believesWe believe that establishing and maintaining itsour brand names is essential to expanding itsour Internet business and attracting new customers. CMGIWe also believesbelieve that the importance of brand name recognition will increase in the future because of the growing number of Internet companies that will need to differentiate themselves. Promotion and enhancement of CMGI'sour brand names will depend largely on CMGI'sour ability to provide consistently high-quality products and services. If CMGI iswe are unable to provide high-quality products and services, the value of itsour brand namenames may suffer. CMGI'SOUR QUARTERLY RESULTS MAY FLUCTUATE WIDELY. CMGI'sOur operating results have fluctuated widely on a quarterly basis during the last several years, and CMGI expectswe expect to experience significant fluctuation in future quarterly operating results. Many factors, some of which are beyond CMGI'sour control, have contributed to these quarterly fluctuations in the past and may continue to do so. Such factors include: o demand for CMGI'sour products and services; o payment of costs associated with CMGI'sour acquisitions, sales of assets and investments; o timing of sales of assets; o market acceptance of new products and services; o specific economic conditions in the Internet and direct marketing industries; and o general economic conditions. The emerging nature of the commercial uses of the Internet makes predictions concerning CMGI'sour future revenues difficult. CMGI believesWe believe that period-to-period comparisons of itsour results of operations will not necessarily be meaningful and should not be relied upon as indicative of CMGI'sour future performance. It is also possible that in some fiscal quarters, CMGI'sour operating results will be below the expectations of securities analysts and investors. In such circumstances, the price of CMGI'sour common stock may decline. THE PRICE OF CMGI'SOUR COMMON STOCK HAS BEEN VOLATILE. The market price of CMGI'sour common stock has been, and is likely to continue to be, volatile, experiencing wide fluctuations. In recent years, the stock market has experienced significant price and volume fluctuations which have particularly impacted the market prices of equity securities of many companies providing Internet-related products and services. Some of these fluctuations appear to be unrelated or disproportionate to the operating performance of such companies. Future market movements may adversely affect the market price of CMGI'sour common stock. OWNERSHIP OF CMGI FACESIS CONCENTRATED. David S. Wetherell, our chairman, president and chief executive officer, beneficially owned approximately 12% of our outstanding common stock as of April 30, 2000. As a result, Mr. Wetherell possesses significant influence over CMGI on matters, including the election of directors. Additionally, Compaq Computer Corporation owned approximately 15% of our outstanding common stock as of April 30, 2000. The concentration of our share ownership may: o delay or prevent a change in our control; o impede a merger, consolidation, takeover, or other transaction involving CMGI; or o discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of CMGI. WE RELY ON NAVISITE FOR WEB SITE HOSTING. We and many of our operating companies rely on NaviSite for network connectivity and hosting of servers. If NaviSite fails to perform such services, our internal business operations may be interrupted, and the ability of our operating companies to provide services to customers may also be interrupted. Such interruptions may have an adverse impact on our business and revenues and our operating companies. CMGI LITIGATION. On February 9, 2000, International Merchandising Corporation and International Managements, Inc. (collectively, "IMG") filed a complaint in the United States District Court for the Northern District of Ohio, Eastern Division, against Signatures SNI, Inc., Signatures Network, Inc. (collectively "Signatures") subsidiaries of iCAST, iCAST, a subsidiary of CMGI, and CMGI. The complaint asserted claims against Signatures for breach of contract, promissory estoppel, and quantum meruit and claims against CMGI and iCAST for tortious interference with contract and tortious interference with prospective contractual relations. The complaint sought compensatory damages of not less than $15,000,000, Signatures stock options, the unspecified value of alleged services performed by IMG, unspecified punitive damages, and costs. On February 22, 2000, IMG filed with the court a motion to compel arbitration. On April 1, 2000, the parties entered into an Alternative Dispute Resolution Agreement, pursuant to which IMG voluntarily withdrew its motion to compel arbitration and agreed to waive its claim for punitive damages. The parties agreed to submit all claims they may have against each other to mediation and, if mediation proves to be unsuccessful, to private, binding arbitration. On April 7, 2000, IMG filed with the court its notice of voluntary dismissal of the federal court action. The parties are currently mediating the dispute. The defendants believe that they have valid defenses to IMG's asserted claims. If we do not prevail, the outcome could adversely affect our financial condition and results of operations. On or about March 15, 2000, CMGI and certain of its officers and directors, as well as certain officers and directors of Engage, a subsidiary of CMGI, were sued by a shareholder of Engage in what purported to be a derivative action on behalf of Engage. The lawsuit is captioned Doris B. Sollod, Plaintiff, v. Edward A. Bennett, Christopher A. Evans, Craig D. Goldman, Andrew J. Hajducky, III, Frederic D. Rosen, Paul L. Schaut, David S. Wetherell and CMGI, Inc., Defendants and Engage Technologies, Inc., Nominal Defendant, Civil Action No. 17886-NC, Court of Chancery, New Castle County, Delaware. The complaint arose out of the intended sale by CMGI of its subsidiaries, Flycast and Adsmart, to Engage, as announced on or about January 20, 2000. The plaintiff alleged, inter alia, that CMGI and the individual defendants violated their fiduciary duties, duties of loyalty and good faith, and engaged in self-dealing with regard to the transaction, which the complaint alleged is unfair to Engage. The complaint requested, inter alia, that the court (1) enjoin the defendants from taking any steps in furtherance of the transaction; (2) award recissory damages to Engage and rescind the transaction if it is consummated; (3) direct the defendants to account to Engage for its damages and CMGI's profits; and (4) award the plaintiff her costs, disbursements and fees. On August 15, 2000, the plaintiff filed a stipulation of dismissal. The parties expect that the court will endorse the stipulation and the matter will be dismissed. Neil Braun, the former president and chief executive officer of iCAST Corporation, a subsidiary of CMGI, filed a complaint in the United States District Court, Southern District of New York, on December 22, 1999 against CMGI, iCAST and David S. Wetherell, chief executive officer and chairman of CMGI, alleging certain claims arising out of the termination of Mr. Braun's employment with iCAST. As set forth in the complaint, Mr. Braun is seeking, among other things, monetary damages in excess of $50 million and specific performance of certain alleged contractual obligations that would require iCAST to deliver to Mr. Braun an equity interest in iCAST. On January 31, 2000, an answer to the complaint was filed on behalf of CMGI, iCAST and Mr. Wetherell. The parties are currently engaged in discovery. The defendants plan to vigorously defend against these claims. If we do not prevail in this proceeding, the outcome could adversely affect our financial condition and results of operations. The parties are currently conducting discovery in this matter. RISKS PARTICULAR TO OUR NETWORK COMPANIES THE SUCCESS OF OUR NETWORK COMPANIES DEPENDS GREATLY ON INCREASED USE OF THE INTERNET BY BUSINESS AND INDIVIDUALS. The success of our network companies depends greatly on increased use of the Internet for advertising, marketing, providing services and conducting business. Commercial use of the Internet is currently at an early stage of development and the future of the Internet is not clear. In addition, it is not clear how effective advertising on the Internet is in generating business as compared to more traditional types of advertising such as print, television and radio. The businesses of our network companies will suffer if commercial use of the Internet fails to grow in the future. OUR NETWORK COMPANIES ARE SUBJECT TO INTENSE COMPETITION. The market for Internet products and services is highly competitive. Moreover, the market for Internet products and services lacks significant barriers to entry, enabling new businesses to enter this market relatively easily. Competition in the market for Internet products and services may intensify in the future. Numerous well-established companies and smaller entrepreneurial companies are focusing significant resources on developing and marketing products and services that will compete with the products and services of our network companies. In addition, many of the current and potential competitors of our network companies have greater financial, technical, operational and marketing resources than those of our network companies. Our network companies may not be able to compete successfully against these competitors. Competitive pressures may also force prices for Internet goods and services down and such price reductions may reduce the revenues of our network companies. GROWING CONCERNS ABOUT THE USE OF "COOKIES" MAY LIMIT ENGAGE'S ABILITY TO DEVELOP USER PROFILES. Web sites typically place small files of information commonly known as "cookies" on a user's hard drive, generally without the user's knowledge or consent. Cookie information is passed to the Web site through the Internet user's browser software. Engage's technology currently uses cookies to collect information about an Internet user's movement through the Internet. Most of the currently available Internet browsers allow users to modify their browser settings to prevent cookies from being stored on their hard drive, and a small minority of users currently choose to do so. Users can also delete cookies from their hard drive at any time. In addition, Microsoft, the leading provider of computer browser software, has announced a plan to modify its product to prompt users in certain situations when cookies are set on a user's computer. Some Internet commentators and privacy advocates have suggested limiting or eliminating the use of cookies, and recently, the FTC initiated an informal inquiry into the data collection practices of DoubleClick, Inc. The effectiveness of Engage's technology could be limited by any reduction or limitation in the use of cookies. If the use or effectiveness of cookies is limited, Engage would likely have to switch to other technology that would allow it to gather demographic and behavioral information. This could require significant reengineering time and resources, might not be completed in time to avoid negative consequences to our business, financial condition or results of operations, and might not be possible at all. IF THE UNITED STATES OR OTHER GOVERNMENTS REGULATE THE INTERNET MORE CLOSELY, THE BUSINESSES OF OUR NETWORK COMPANIES MAY BE HARMED. Because of the Internet's popularity and increasing use, new laws and regulations may be adopted. These laws and regulations may cover issues such as privacy, pricing, taxation and content. The enactment of any additional laws or regulations may impede the growth of the Internet and the Internet-related business of our network companies and could place additional financial burdens on their businesses. TO SUCCEED, OUR NETWORK COMPANIES MUST RESPOND TO THE RAPID CHANGES IN TECHNOLOGY AND DISTRIBUTION CHANNELS RELATED TO THE INTERNET. The markets for the Internet products and services of our network companies are characterized by: o rapidly changing technology; o evolving industry standards; o frequent new product and service introductions; o shifting distribution channels; and o changing customer demands. The success of our network companies will depend on their ability to adapt to this rapidly evolving marketplace. They may not be able to adequately adapt their products and services or to acquire new products and services that can compete successfully. In addition, our network companies may not be able to establish and maintain effective distribution channels. OUR NETWORK COMPANIES FACE SECURITY RISKS. The secure transmissionConsumer concerns about the security of transmissions of confidential information over public telecommunications facilities is a significant barrier to electronic commerce and communications on the Internet. Many factors may cause compromises or breaches of the security systems used by CMGIour network companies or other Internet sites use to protect proprietary information, including advances in computer and software functionality or new discoveries in the field of cryptography. A compromise of security on the Internet would have a negative effect on the use of the Internet for commerce and communications and negatively impact CMGI's business.our network companies' businesses. Security breaches of their activities or the activities of CMGI, itstheir customers and sponsors involving the storage and transmission of proprietary information, such as credit card numbers, may expose CMGIour network companies to a risk of loss or litigation and possible liability. CMGIWe cannot assure that itsthe security measures of our network companies will prevent security breaches. OWNERSHIP OF CMGI IS CONCENTRATED. David S. Wetherell, CMGI's chairman, president, and chief executive officer, beneficially owned approximately 15% of CMGI's outstanding common stock as of October 22, 1999. As a result, Mr. Wetherell possesses significant influence over CMGI on matters including the election of directors. Additionally, Compaq Computer Corporation and its wholly owned subsidiary Digital Equipment Corporation owned approximately 18% of CMGI's outstanding common stock as of October 28, 1999. The concentration of CMGI's share ownership may: o delay or prevent a change in control of CMGI; o impede a merger, consolidation, takeover, or other transaction involving CMGI; or o discourage a potential acquiror from making a tender offer or otherwise attempting to obtain control of CMGI. CMGI'S BUSINESS WILL SUFFER IF ANY OF ITS PRODUCTS OR SYSTEMS, OR THE PRODUCTS OR SYSTEMS OF THIRD PARTIES ON WHICH CMGI RELIES, FAIL TO BE YEAR 2000 COMPLIANT. Many currently installed computer systems and software products are coded to accept only two digit entries in the date code field. These date code fields will need to accept four digit entries distinguishing 21st century dates from 20th century dates in order to be year 2000 compliant. CMGI's products and systems and those of third parties on whom CMGI relies may fail to be year 2000 compliant. CMGI's failure to resolve year 2000 issues may damage its business and expose CMGI to third party liability. If third party equipment or software used in CMGI's business is not year 2000 compliant, CMGI may incur significant unanticipated expenses to remedy such problems. CMGI also relies on vendors, utility companies, telecommunications service companies, delivery service companies and other service providers, each of which may not be year 2000 compliant. As of July 31, 1999, CMGI had incurred approximately $3 million in connection with year 2000 compliance and expects to incur an additional $1.5 to $2.0 million. Because of CMGI's recent acquisitions of a number of companies in varying stages of year 2000 compliance assessment and unforeseeable year 2000 expenses, CMGI's year 2000 costs may exceed these estimates. NaviSite, a subsidiary of CMGI that hosts and provides application management services, may fail to be year 2000 compliant. NaviSite may be exposed to additional year 2000 risks because its customers, or their outside service providers, have customized much of the customer-provided hardware and software hosted at NaviSite's data centers. NaviSite's customers are responsible for their year 2000 compliance. However, CMGI cannot assure you that NaviSite's customers will be year 2000 compliant. Many of CMGI's majority owned subsidiaries rely on NaviSite in connection with their businesses. NaviSite's failure to be year 2000 compliant may negatively impact these subsidiaries. CMGI RELIES ON NAVISITE FOR NETWORK CONNECTIVITY. CMGI and many of its majority owned subsidiaries rely on NaviSite for network connectivity and hosting of servers. If NaviSite fails to perform such services, CMGI's internal business operations may be interrupted, and the ability of CMGI's majority owned subsidiaries to provide services to customers may also be interrupted. Such interruptions may have an adverse impact on the business and revenues of CMGI and its majority owned subsidiaries. THE SUCCESS OF CMGI'STHE GLOBAL OPERATIONS OF OUR NETWORK COMPANIES IS SUBJECT TO SPECIAL RISKS AND COSTS. CMGI hasOur network companies have begun, and intendsintend to continue, to expand itstheir operations outside of the United States. This international expansion will require significant management attention and financial resources. CMGI'sThe ability of our network companies to expand their offerings of itsour products and services internationally will be limited by the general acceptance of the Internet and intranets in other countries. In addition, CMGI haswe and our network companies have limited experience in such international activities. Accordingly, CMGI expectswe and our network companies expect to commit substantial time and development resources to customizing itsthe products and services of our network companies for selected international markets and to developing international sales and support channels. CMGI expectsWe expect that itsthe export sales of our network companies will be denominated predominantly in United States dollars. As a result, an increase in the value of the United States dollar relative to other currencies may make CMGI'sthe products and services of our network companies more expensive and, therefore, potentially less competitive in international markets. As CMGI increases itsour network companies increase their international sales, itstheir total revenues may also be affected to a greater extent by seasonal fluctuations resulting from lower sales that typically occur during the summer months in Europe and other parts of the world. CMGIOUR NETWORK COMPANIES COULD BE SUBJECT TO INFRINGEMENT CLAIMS. From time to time, CMGI hasour network companies have been, and expectsexpect to continue to be, subject to third party claims in the ordinary course of business, including claims of our alleged infringement of intellectual property rights by CMGI.rights. Any such claims may damage CMGI's businessthe businesses of our network companies by: o subjecting CMGIthem to significantsignifican liability for damages; o invalidating CMGI'sresulting in invalidation of their proprietary rights; o being time-consuming and expensive to defend even if such claims are not meritorious; and o resulting in the diversion of management time and attention. CMGIOUR NETWORK COMPANIES MAY HAVE LIABILITY FOR INFORMATION RETRIEVED FROM THE INTERNET. Because materials may be downloaded from the Internet and subsequently distributed to others, CMGIour network companies may be subject to claims for defamation, negligence, copyright or trademark infringement, personal injury or other theories based on the nature, content, publication and distribution of such materials.

COMMON STOCK Voting Rights. Each holder of common stock is entitled to one vote on all matters to be voted upon by stockholders for each share held on the record date for such vote. Dividends. The holders of common stock, after preferences of holders of preferred stock, are entitled to receive dividends when, as and if declared by the board of directors out of funds legally available for dividends. Liquidation and Dissolution. If we are liquidated or dissolved, the holders of the common stock will be entitled to share in our assets available for distribution to stockholders in proportion to the amount of common stock they own. The amount available for common stockholders is calculated after payment of liabilities. Holders of preferred stock will receive their preferential share of our assets before the holders of the common stock receive any assets. Other Rights. Holders of the common stock have no right to: o convert the common stock into any other security, o have the common stock redeemed, or o purchase additional shares of common stock to maintain their proportionate interest. The common stock does not have cumulative voting rights, which means that the holders of a majority of the shares can elect all the directors and that the holders of the remaining shares will not be able to elect any directors. All outstanding shares of common stock are, and all shares of common stock offered under a this prospectus when issued will be upon payment, validly issued, fully paid and nonassessable. Restriction on Alienability of Securities to be Registered. The common stock being registered herein is subject to a Trading Day Limit Agreement between us and each selling stockholder. Under this agreement, the selling stockholder can, on any single day on which Nasdaq is open for trading, sell only up to 10% of the total shares issued to the selling stockholder upon payment of any of the notes. In addition, the selling stockholder can, beginning on the date on which the selling stockholder is issued shares upon payment of any of the notes and ending ten trading days thereafter, enter into a swap, hedge, collar, short sale or other arrangement that transfers to another any of the consequences of ownership of those shares for that period. Transfer Agent. We have appointed EquiServe, L.P. as the transfer agent and registrar for our common stock. PREFERRED STOCK General. Our restated certificate of incorporation authorizes the board of directors to issue, without any further action by the stockholders, the preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences and rights of the shares of each series and the qualifications, limitations or restrictions thereof, including voting rights, dividend rights, conversion rights, liquidation preferences, redemption privileges and sinking fund terms. The rights, preferences, privileges and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to that series. Any or all of the rights of the preferred stock may be greater than the rights of the common stock. In addition, the preferred stock could have other rights, including economic rights senior to our common stock, so that the issuance of the preferred stock could adversely affect the market value of our common stock. The issuance of the preferred stock may also have the effect of delaying, deferring or preventing a change in control of us without any action by the stockholders. SERIES C PREFERRED STOCK Voting Rights. Holders of shares of Series C preferred stock have no voting rights except as otherwise provided by the Delaware corporation statute and our restated certificate of incorporation. On such matters where the holders of shares of Series C preferred stock have a right to vote with the holders of common stock, they are entitled to vote their shares on an as-converted basis. Our restated certificate of incorporation also gives the holders of shares of Series C preferred stock the right to vote on enumerated actions that if taken by us would impair their rights, preferences and privileges. Prior to us taking any such action, the affirmative vote of the holders of a majority of the outstanding shares of Series C preferred stock is required. Dividend Rights. Holders of Series C convertible preferred stock are entitled to receive when, as and if declared by the board of directors, out of funds legally available for dividends, cumulative dividends equal to two percent per annum of the stated value of $1,000 per share, payable semiannually in arrears, either in cash or, at our option, through an adjustment to the liquidation preference per share. Such adjustments, if any, will also increase the number of shares of common stock into which shares of Series C preferred stock is convertible. Liquidation and Dissolution. In the event of any liquidation or dissolution of us, the holders of Series C preferred stock are entitled to receive, prior to any distribution to holders of common stock, an amount equal to the stated value of $1,000 per share plus all adjustments to the liquidation preference plus accrued but unpaid dividends to which no adjustment has been made (the sum of which is referred to as the liquidation preference). Our restated certificate of incorporation specifies that upon the occurrence of enumerated corporate events, including the consummation of a transaction in which our stockholders do not own at least 50% of the voting power of the combined company, the holders of two-thirds of the outstanding shares of Series C preferred stock may elect either: o to treat such events as a liquidation event and receive a liquidation distribution; or o to have the conversion price for each share of Series C preferred stock adjusted accordingly. Conversion. The shares of Series C preferred stock are segregated into three equal tranches of 125,000 shares each. The shares in each tranche have identical rights and preferences except as to conversion. The conversion price calculated for each tranche is also subject to adjustment for certain actions described in our restated certificate of incorporation. Shares of Series C preferred stock may be converted into common stock at any time at the option of the holders and automatically convert into common stock on June 30, 2002, as described in the restated certificate of incorporation. The restated certificate of incorporation provides that a holder of Series C preferred stock may not choose to convert such shares into common stock totaling more than 9.9% of outstanding shares of common stock. Redemption Rights. Holders of shares of Series C preferred stock have the right to cause us to redeem their shares upon the occurrence of events specified in our restated certificate of incorporation, including our failure to issue shares of common stock upon conversion by holders of shares of Series C preferred stock. The redemption price will be an stock demanding redemption. CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK We have shares of common stock and preferred stock available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, facilitate corporate acquisitions or payable as a dividend on the capital stock. The existence of unissued and unreserved common stock and preferred stock may enable the board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, the issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. CERTAIN PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION AND THE RESTATED BY-LAWS Our restated certificate of incorporation and restated by-laws include provisions that could make it more difficult to acquire us by means of a merger, tender offer, proxy contest or otherwise. These provisions, as described below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us first to negotiate with us. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because, among other things, negotiations with respect to such proposals could result in terms more favorable to us. Our restated certificate of incorporation and restated by-laws provide that the board of directors will be divided into three classes of directors, with the term of each class expiring in a different year. Our restated by-laws provide that the number of directors will be fixed from time to time exclusively by the board of directors, but shall consist of not more than fifteen nor less than three directors. A majority of the board of directors then in office has the sole authority to fill any vacancies on the board of directors. Our restated certificate of incorporation provides that directors may be removed only by the affirmative vote of holders of at least 75% of the voting power of all of the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. Our restated certificate of incorporation provides that stockholder action can be taken only at an annual or special meeting of stockholders and prohibits stockholder action by written consent in lieu of a meeting. Our restated certificate of incorporation and restated by-laws provide that special meetings of stockholders can be called by the chairman of the board of directors, or pursuant to a resolution approved by a majority of the total number of directors which we would have if there were no vacancies on the board of directors, or by the stockholders owning at least 20% of the stock entitled to vote at the meeting. The business permitted to be conducted at any special meeting of stockholders is limited to the business brought before the meeting by the chairman of the board, or at the request of a majority of the whole board of directors, or as specified in the stockholders' call for such meeting. Our restated by-laws set forth an advance notice procedure with regard to the nomination, other than by or at the direction of the board of directors, of candidates for election to the board of directors and with regard to business brought before an annual meeting of stockholders. Our restated certificate of incorporation and restated by-laws contain provisions requiring the affirmative vote of the holders of at least 75% of the voting stock, voting together as a single class, to amend certain provisions of the restated certificate of incorporation relating primarily to anti-takeover provisions and to the limitation of director liability. The restated certificate of incorporation empowers the board of directors, when considering a tender offer or merger or acquisition proposal, to take into account factors in addition to potential economic benefits to stockholders. Such factors may include: o comparison of the proposed consideration to be received by stockholders in relation to the then current market price of the capital stock, our estimated current value in a freely negotiated transaction, and our estimated future value as an independent entity; o the impact of such a transaction on ou customers and employees, and its effect on the communities in which we operate; and o our ability to fulfill our objectives under applicable statutes and regulations. Our restated certificate of incorporation prohibits us from purchasing any shares of our stock from any person, entity or group that beneficially owns 5% or more of our voting stock at a price exceeding the average closing price for the twenty trading business days prior to the purchase date, unless a majority of our disinterested stockholders approve the transaction. This restriction on purchases by us does not apply to any offer to purchase shares of a class of our stock which is made on the same terms and conditions to all holders of that class of stock, to any purchase of stock owned by such a 5% stockholder occurring more than two years after such stockholder's last acquisition of our stock, to any purchase of our stock in accordance with the terms of any stock option or employee benefit plan, or to any purchase at prevailing market prices pursuant to a stock purchase program. Our restated certificate of incorporation contains a provision requiring the affirmative vote of the holders of at least 75% of the voting stock, voting together as a single class, to approve any business combination not approved by the affirmative vote of a majority of the total number of directors. This requirement is in addition to the requirements of Section 203 of the Delaware General Corporation Law. CMGI, INC. CMGI develops and operates Internet and fulfillment services companies.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statementregistration statement or any material change to such information in the Registration Statement;registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrantregistrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment 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. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrantregistrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant'sregistrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statementregistration statement 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.
