PROXY STATEMENT
For the Annual Meeting of Stockholders
To Be Held December 19, 2001


General

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of CMGI, Inc., a Delaware corporation (the "Company"), for use at the Company's 2001 Annual Meeting of Stockholders (the "Meeting"), which will be held at The Andover Country Club, 60 Canterbury Street, Andover, Massachusetts 01810, on Wednesday, December 19, 2001, at 9:00
a.m. local time, and at any adjournment thereof. The Notice of Annual Meeting, this Proxy Statement, the accompanying proxy card and the Company's Annual Report to Stockholders for the year ended July 31, 2001 are being mailed to stockholders on or about November 16, 2001. The Company's principal executive offices are located at 100 Brickstone Square, Andover, Massachusetts 01810 and its telephone number is (978) 684-3600.

All share numbers and share prices provided in this Proxy Statement have been adjusted to reflect all stock splits effected prior to the date hereof.

Solicitation

The cost of soliciting proxies, including expenses in connection with preparing and mailing this Proxy Statement, will be borne by the Company. Copies of solicitation materials will be furnished to brokerage houses, nominees, fiduciaries and custodians to forward to beneficial owners of Common Stock held in their names. In addition, the Company will reimburse brokerage firms and other persons representing beneficial owners of stock for their reasonable expenses in forwarding solicitation materials to such beneficial owners. In addition to original solicitation of proxies by mail, the Company's directors, officers and other employees may, without additional compensation, solicit proxies by telephone, facsimile, electronic communication and personal interviews.

Record Date, Outstanding Shares and Voting Rights

The Board of Directors has fixed November 2, 2001 as the record date for determining holders of the Company's Common Stock, $.01 par value per share (the "Common Stock"), who are entitled to vote at the Meeting. As of November 2, 2001, the Company had approximately 352,848,926 shares of Common Stock outstanding and entitled to be voted. Each share of Common Stock entitles the record holder to one vote on each matter to be voted upon at the Meeting. A majority of the shares of Common Stock issued and outstanding and entitled to vote at the Meeting will constitute a quorum at the Meeting. Votes withheld, abstentions and broker non-votes shall be counted for purposes of determining the presence or absence of a quorum for the transaction of business at the Meeting.

The affirmative vote of the holders of a plurality of the votes cast at the Meeting is required for the election of directors. The affirmative vote of the holders of a majority of the shares of Common Stock present or represented by proxy and voting on the matter is required to approve the amendment to the Employee Stock Purchase Plan, to ratify the appointment of the Company's independent auditors and to approve the stockholder proposal.

Shares which abstain from voting on a particular matter and shares held in "street name" by brokers or nominees who indicate on their proxies that they do not have discretionary authority to vote such shares as to a particular matter ("broker non-votes") will not be counted as votes in favor of such matter, and will also not be


counted as votes cast or shares voting on such matter. Accordingly, abstentions and broker non-votes will have no effect on the voting for the election of directors, which requires the affirmative vote of a plurality of the votes cast or shares voting on the matter. In addition, abstentions and broker non-votes will have no effect on the voting on the remaining matters to be voted on at the Meeting, each of which requires the affirmative vote of a majority of the votes cast or shares voting on the matter.

To vote by mail, sign, date and complete the enclosed proxy card and return it in the enclosed envelope. No postage is necessary if the proxy card is mailed in the United States. If you hold your shares through a bank, broker or other nominee, they will give you separate instructions for voting your shares.

Revocability of Proxy and Voting of Shares

Any stockholder giving a proxy has the power to revoke it at any time before it is exercised. The proxy may be revoked by filing with the Secretary of the Company, at the principal executive offices of the Company, 100 Brickstone Square, Andover, Massachusetts 01810, an instrument of revocation or a duly executed proxy bearing a later date. The proxy may also be revoked by attending the Meeting and voting in person. If not revoked, the proxy will be voted at the Meeting in accordance with the stockholder's instructions indicated on the proxy card. If no instructions are indicated, the proxy will be voted:

. FOR the election of the two Class II Director nominees named herein;

. FOR the approval of the amendment to the Company's Employee Stock Purchase Plan;

. FOR the ratification of the appointment of KPMG LLP as the Company's independent auditors for the current fiscal year;

. AGAINST the stockholder proposal; and

. In accordance with the judgment of the proxy holders as to any other matter that may be properly brought before the Meeting or any adjournments thereof.

Board and Committee Meetings

During the fiscal year ended July 31, 2001 ("fiscal 2001"), the Board of Directors held 23 meetings (including by telephone conference).

The Board of Directors has an Audit Committee, which assists the Board of Directors in fulfilling its responsibilities to stockholders concerning the Company's financial reporting and internal controls, and facilitates open communication among the Audit Committee, Board of Directors, outside auditors and management. The Audit Committee discusses with management and the outside auditor the financial information developed by the Company, the Company's systems of internal controls and the Company's audit process. The Audit Committee recommends to the Board each fiscal year the independent auditors who will audit the books of the Company for that year. The independent auditors meet with the Audit Committee (both with and without the presence of the Company's management) to review and discuss various matters pertaining to the audit, including the Company's

PROPOSAL 2

APPROVAL OF AMENDMENT TO THE EMPLOYEE STOCK PURCHASE PLAN

On October 19, 2001, the Board of Directors adopted resolutions, subject to stockholder approval, to approve an amendment (the "ESPP Amendment") to the Company's 1995 Employee Stock Purchase Plan, as amended (the "ESPP"), to increase the number of shares of Common Stock authorized for issuance under the ESPP from 1,000,000 shares to 3,000,000 shares. The Board has adopted the ESPP Amendment because the number of shares currently available under the ESPP is insufficient to satisfy the expected foreseeable future share requirements thereunder.

As of November 16, 2001, 297,270 shares of Common Stock were available for issuance under the ESPP. If stockholders approve the ESPP Amendment, 2,297,270 shares will be available for issuance under the ESPP. Because participation in the ESPP is voluntary, the Company cannot now determine the number of shares of Common Stock to be purchased by any particular individual or group of individuals.

Summary of the ESPP

The ESPP qualifies as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). All employees of the Company, including directors of the Company who are employees, and all the employees of any participating subsidiaries whose customary employment is more than 20 hours per week and for more than five months in any calendar year are eligible to participate in the ESPP. Employees who would immediately after the grant own 5% or more of the total combined voting power or value of the stock of the Company or any subsidiary are not eligible to participate. As of September 30, 2001, approximately 2,818 of the Company's employees were eligible to participate in the ESPP.

The ESPP provides for a participating employee's authorization of the Company's deduction of funds from an employee's pay for the purchase of shares of Common Stock on a given date. For any offering period, a

6

participant may authorize a payroll deduction from his or her compensation of
(i) between 1% and 10% in increments of 1% or (ii) any whole dollar amount not less than $10 per pay period and $100 per offering period. The Company offers shares of Common Stock to eligible employees during offering periods which coincide with the Company's fiscal quarters.

On the first day of each offering period, the participant will receive an option to purchase up to, but no more than, the number of shares of Common Stock calculated by dividing the closing market price of the Common Stock on the first trading day of the offering period into $6,250. In addition, no participant shall be permitted to purchase shares of common stock under all the employee stock purchase plans of the Company and its subsidiaries at a rate which exceeds $25,000 in fair market value (measured at the time the option is granted) of such stock for each calendar year. On the last trading day of the offering period, the participant's option will be automatically exercised and the participant's account will be used to buy shares of Common Stock at a price equal to 85% of the closing price of the Common Stock on either (i) the first trading day of the offering period or (ii) the last trading day of the offering period, whichever is lower.

An employee's participation in the ESPP will be terminated when the employee
(i) voluntarily elects to withdraw his or her entire account, (ii) resigns or is discharged from the Company or (iii) dies. Upon termination of participation, the employee shall not be entitled to rejoin the ESPP until the first day of the offering period immediately following the offering period in which the employee terminates his or her participation. Upon the death of a participant, his or her account shall be paid or distributed to the beneficiary or beneficiaries designated by such participant, or in the absence of such designation, to the executor or administrator of his or her estate. Participants' rights under the ESPP may not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the Participant, are exercisable only by the participant. The Board may amend, alter or terminate the ESPP at any time.

Federal Income Tax Consequences

The following is a summary of the United States federal income tax consequences that generally will arise with respect to purchases made under the ESPP and with respect to the sale of Common Stock acquired under the ESPP. This summary is based on the federal tax laws in effect as of the date of this proxy statement. Changes to these laws could alter the tax consequences described below.

Tax Consequences to Participants. In general, a participant will not recognize taxable income upon enrolling in the ESPP or upon purchasing shares of Common Stock at the end of an offering. Instead, if a participant sells Common Stock acquired under the ESPP at a sale price that exceeds the price at which the participant purchased the Common Stock, then the participant will recognize taxable income in an amount equal to the excess of the sale price of the Common Stock over the price at which the participant purchased the Common Stock. A portion of that taxable income will be ordinary income, and a portion may be capital gain.

If the participant sells the Common Stock more than one year after acquiring it and more than two years after the date on which the offering commenced (the "Grant Date"), then the participant will be taxed as follows. If the sale price of the Common Stock is higher than the price at which the participant purchased the Common Stock, then the participant will recognize ordinary compensation income in an amount equal to the lesser of:

(i) fifteen percent of the fair market value of the Common Stock on the Grant Date; and

(ii) the excess of the sale price of the Common Stock over the price at which the participant purchased the Common Stock.

Any further income will be long-term capital gain. If the sale price of the Common Stock is less than the price at which the participant purchased the Common Stock, then the participant will recognize long-term capital loss in an amount equal to the excess of the price at which the participant purchased the Common Stock over the sale price of the Common Stock.

If the participant sells the Common Stock within one year after acquiring it or within two years after the Grant Date (a "Disqualifying Disposition"), then the participant will recognize ordinary compensation income

7

in an amount equal to the excess of the fair market value of the Common Stock on the date that it was purchased over the price at which the participant purchased the Common Stock. The participant will also recognize capital gain in an amount equal to the excess of the sale price of the Common Stock over the fair market value of the Common Stock on the date that it was purchased, or capital loss in an amount equal to the excess of the fair market value of the Common Stock on the date that it was purchased over the sale price of the Common Stock. This capital gain or loss will be a long-term capital gain or loss if the participant has held the Common Stock for more than one year prior to the date of the sale and will be a short-term capital gain or loss if the participant has held the Common Stock for a shorter period.

Tax Consequences to the Company. The offering of Common Stock under the ESPP will have no tax consequences to the Company. Moreover, in general, neither the purchase nor the sale of Common Stock acquired under the ESPP will have any tax consequences to the Company except that the Company will be entitled to a business-expense deduction with respect to any ordinary compensation income recognized by a participant upon making a Disqualifying Disposition. Any such deduction will be subject to the limitations of Section 162(m) of the Code.

The Board of Directors recommends that the stockholders vote FOR the adoption of the amendment to the ESPP.

PROPOSAL 3

RATIFICATION OF THE APPOINTMENT OF AUDITORS

The Board of Directors has appointed KPMG LLP, independent auditors ("KPMG"), to audit the Company's consolidated financial statements for the fiscal year ending July 31, 2002 ("fiscal 2002"), and recommends that the stockholders vote for ratification of such appointment. If the stockholders do not ratify the selection of KPMG as the Company's independent auditors, the selection of such auditors will be reconsidered by the Board of Directors. A representative of KPMG, which served as the Company's auditors in fiscal 2001, is expected to be present at the Meeting to be available to respond to appropriate questions from stockholders and to make a statement if he or she desires to do so.

The Board of Directors recommends that the stockholders vote FOR the ratification of KPMG to serve as the Company's independent auditors for the current fiscal year.

STOCKHOLDER PROPOSAL

Gary M. Mucica, 7 Olympic Lane, North Andover, Massachusetts 01845, owner of at least 5,000 shares of Common Stock, has notified the Company that he intends to present the following proposal at the Meeting:

"Whereas it is vital that Officers and Directors of publicly traded companies should align their personal financial interests with those of the shareholders it is resolved that CMGI, Inc. follow the lead of numerous other publicly traded corporations and adopt the following shareholding requirements:

All Officers and Directors of CMGI, Inc. or any of its majority owned subsidiaries be required to personally own, apart from unexercised stock options and other deferred compensation, shares of the company's common stock equal to their most recent annual cash compensation including salary, cash bonus and directors fee or $100,000 whichever is greater. The amount of required stock ownership will be adjusted at the end of each fiscal based on changes to their compensation and the market value of the company's common stock."

The Board of Directors recommends that the stockholders vote AGAINST this stockholder proposal.

The Board believes that this proposal is not in the best interests of the Company or its stockholders. While the Board agrees that it is important to align the interests of management and members of the Board with those of the stockholders, the Board strongly believes that it is equally important to attract, motivate and retain the highly talented individuals the Company needs to be a leader in its highly competitive market. The Board feels that the stockholder proposal, if adopted, would make it exceedingly difficult for the Company to attract and retain high quality personnel to fill management positions and Board seats at the Company and at its operating companies. To overcome this counterproductive hurdle and comply with the stockholder proposal, the Company would be forced to waste valuable resources, including cash and shares of its Common Stock, that should be invested elsewhere to create stockholder value. The Board believes that its current compensation programs, including stock options, performance-based stock options and cash incentive awards, adequately align the interests of management and members of the Board with those of the stockholders and therefore recommends a vote AGAINST the proposal.

The Board of Directors recommends that the stockholders vote AGAINST the stockholder proposal.

1999 Stock Option Plan for Non-Employee Directors

All directors of the Company are eligible to receive non-statutory stock options to purchase shares of Common Stock under the Company's 1999 Stock Option Plan for Non-Employee Directors, as amended (the "Director Plan"), except for any director who (i) is an employee of the Company or any of its subsidiaries or affiliates or (ii) unless otherwise determined by the Board, is an affiliate, employee or designee of an institutional or corporate investor in the Company (an "Affiliated Director").

Each eligible director who is elected to the Board for the first time will be granted an option to acquire 200,000 shares of Common Stock (the "Initial Option"). Each Affiliated Director who ceases to be an Affiliated Director and is not otherwise an employee of the Company or any of its subsidiaries or affiliates will be granted, on the date such director ceases to be an Affiliated Director but remains as a member of the Board of Directors, an Initial Option to acquire 200,000 shares of Common Stock under the Director Plan. Each Initial Option will vest and become exercisable as to 1/36th of the number of shares of Common Stock originally subject to the option on each monthly anniversary of the date of grant, provided that the optionee serves as a director on such monthly anniversary date.

10

On each anniversary of the grant of the Initial Option, each eligible director will automatically be granted an option to purchase 24,000 shares of Common Stock (an "Annual Option"), provided that such eligible director serves as a director on the applicable anniversary date. Each Annual Option will vest and become exercisable on a monthly basis as to 1/12th of the number of shares originally subject to the option commencing on the 37th month after the grant date, provided that the optionee then serves as a director on such monthly anniversary date.

The option exercise price per share for each option granted under the Director Plan shall equal the closing price of the Common Stock on the Nasdaq National Market on the date of grant. Except as otherwise provided in the applicable option agreement, each option granted under the Director Plan shall terminate, and may no longer be exercised, on the date ten years after the date of grant of such option.

On February 21, 2001, Peter McDonald was granted an Initial Option under the Director Plan to purchase 96,000 shares of Common Stock at an exercise price of $4.063 per share.

(1) The exercise price per share of each option was determined to be equal to the fair market value per share of the underlying stock on the date of grant.
(2) Amounts reported in these columns represent hypothetical amounts that may be realized upon exercise of the options immediately prior to the expiration of their term assuming the specified compounded rates of appreciation (5% and 10%) on the underlying common stock over the term of the options. These numbers are calculated based on rules promulgated by the Securities and Exchange Commission and do not reflect the Company's estimate of future stock price growth. Actual gains, if any, on stock option exercises and Common Stock and subsidiary common stock holdings are dependent on the timing of such exercise and the future performance of the underlying common stock. There can be no assurance that the rates of appreciation assumed in this table can be achieved or that the amounts reflected will be received by the option holder.

With respect to the NaviPath, MyWay and SalesLink options, the value of the unexercised in-the-money options is based on the difference between the approximate fair market value per share of the underlying common stock on July 31, 2001, as determined by an independent valuation consultant and approved by the Board of Directors of the respective company, and the applicable option exercise prices.

The Compensation Committee reviews and administers the Company's 2000 Stock Incentive Plan, 1986 Stock Option Plan and Employee Stock Purchase Plan. The Compensation Committee reviews executive compensation reports prepared by independent organizations in order to evaluate the appropriateness of its executive compensation program.

The Compensation Committee uses its base salary and incentive bonus program for the Company's executive officers in order to enhance short-term profitability and stockholder value and uses stock options and performance- based stock options to enhance long-term growth in profitability, return on equity and stockholder value. In order to meet these objectives, the Compensation Committee sets base salaries and target incentive bonus awards for the Company's executive officers for each fiscal year based on percentage of the ranges of base salaries and bonuses among competitive peer groups.

The Compensation Committee reviews the Company's annual performance plan for the ensuing fiscal year and sets specific incentive target bonus awards which are directly linked to the short-term financial performance

14

of the Company as a whole. For fiscal 2001, the Compensation Committee adopted an Executive Bonus Plan which set financial and operating performance measurements. Bonus payments to the executive officers of the Company under the plan may range from 0-200% of an individual's target bonus based on actual performance. No bonus payments were made to executive officers, including the chief executive officer, of the Company under the plan, as the Company did not achieve minimum threshold performance objectives. For fiscal 2002, the Compensation Committee has adopted a Bonus Plan for CMGI Corporate and a Bonus Plan for Operating Companies. Each of these plans covers executive officers and key employees, and are funded based on the Company's business performance, with minimum threshold levels established. Bonus payments under the plans may then range from 0-150% of an individual's target bonus based on achievement of the individual's goals and objectives. In addition, the Compensation Committee has discretionary authority to award bonuses for individual achievements.

In addition to salaries and incentive bonuses, the Compensation Committee also grants stock options to executive officers and other key employees of the Company and its subsidiaries in order to focus the efforts of these employees on the long-term enhancement of profitability and stockholder value.

With respect to the Chief Executive Officer of the Company, the Compensation Committee utilizes a compensation program composed of base salary, incentive bonuses based on financial performance of the Company and individual performance during the fiscal year, and stock option grants. In November 1993, the Company entered into an Employment Agreement with Mr. Wetherell and in connection therewith issued to him a performance-based stock option for the purchase of 4,800,000 shares of Common Stock of the Company. Pursuant to the Employment Agreement, the Compensation Committee fixed Mr. Wetherell's salary for fiscal 2001 at $530,000, which represented no change from the prior fiscal year. In recognition of the Company's current state of unprofitability, Mr. Wetherell has agreed to decrease his base salary for fiscal 2002 to $1. No bonus was paid to Mr. Wetherell for fiscal 2001. While Mr. Wetherell has also elected to forego participation in the Company's Bonus Plan for CMGI Corporate, the Compensation Committee has determined to make him eligible to receive a cash bonus for fiscal 2002 based on financial performance of the Company. See "Employment Agreements and Severance and Change of Control Arrangements." No stock options were granted to Mr. Wetherell during fiscal 2001.

For a discussion of the Company's @Ventures Internet investment and development entities, and the interests of Mr. Wetherell therein, see "Certain Relationships and Related Transactions."

Section 162(m) of the Code generally disallows a tax deduction to public companies for certain compensation in excess of $1 million paid to the company's chief executive officer and the four other most highly compensated executive officers. Certain compensation, including qualified performance- based compensation, will not be subject to the deduction limit if certain requirements are met. In general, the Company structures and administers its stock option plans in a manner intended to comply with the performance-based exception to Section 162(m). Nevertheless, there can be no assurance that compensation attributable to awards granted under the Company's stock option plans will be treated as qualified performance-based compensation under
Section 162(m). In addition, the Compensation Committee reviews the potential effect of Section 162(m) periodically and uses its judgment to authorize compensation payments that may be subject to the limit when the Compensation Committee believes such payments are appropriate and in the best interests of the Company and its stockholders.

The Compensation Committee believes that the foregoing combination of base salaries, incentive bonuses, stock options and performance-based stock options have helped develop a senior management group dedicated to achieving significant improvement in both the short-term and long-term financial performance of the Company.

Audit Committee Report

The Audit Committee of the Board of Directors has reviewed and discussed the Company's audited financial statements for fiscal 2001 with the Company's management. The Audit Committee has discussed with KPMG, the Company's independent auditors, the matters required to be discussed by Statement on Auditing Standards No. 61. The Audit Committee has received the written disclosures and the letter from KPMG required by Independence Standards Board Standard No. 1 and has discussed with KPMG its independence. The Audit Committee also considered whether KPMG's provision of non-audit services, including financial information systems design and implementation services, to the Company is compatible with maintaining KPMG's independence. Based on the review and discussions described above, among other things, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for fiscal 2001.

Compaq Computer Corporation

In connection with the Company's acquisition of AltaVista in August 1999, the Company issued promissory notes to Compaq in the aggregate principal amount of $220 million (the "Notes"). Interest on the Notes, at a rate of 10.5% per annum, is due and payable semiannually on each February 18 and August 18 until the Notes are paid in full. Any principal and interest on the Notes is payable, at the option of the Company, in cash, marketable securities (as defined in the Notes) or any combination thereof. On August 18, 2000, the Company issued an aggregate of 312,547 shares of Common Stock to Compaq in satisfaction of interest due and payable on the Notes. On February 18, 2001, the Company issued an aggregate of 2,013,948 shares of Common Stock to Compaq in satisfaction of interest due and payable on the Notes.

In connection with the AltaVista acquisition, the Company agreed that for so long as Compaq owns at least 5% of the issued and outstanding stock of the Company, Compaq shall have the right to designate a member of the Board of Directors of the Company.

19

In connection with the AltaVista acquisition, the Company and Compaq entered into a strategic business agreement pursuant to which each party agreed to promote and purchase, in some cases, the products or services of the other. These arrangements include (i) the payment of fees by the Company to Compaq for certain Internet traffic directed by Compaq to designated web sites of the Company or its subsidiaries, (ii) an agreement by the Company to spend a specified portion of its information technology budget on products or services offered by Compaq that meet the Company's requirements, (iii) an agreement between the Company and Compaq to provide one another its services and/or products on terms equal to its most favorable then-offered pricing terms, and
(iv) an agreement to create a joint marketing fund for marketing activities which promote the parties' strategic relationship, products and services. From August 1, 2000 through October 31, 2001, the Company made payments to Compaq totaling approximately $70.4 million pursuant to the strategic business agreement.

AltaVista has issued a convertible demand note to Compaq as payment for all debt incurred by AltaVista to Compaq. Under the note, debt accrues interest at a rate of 7% per year, compounded monthly until Compaq elects to convert the debt into shares of Series A convertible preferred stock of AltaVista. Each share of Series A convertible preferred stock of AltaVista is currently convertible into ten shares of common stock of AltaVista. As of October 31, 2001, Compaq owned 128,302 shares of Series A convertible preferred stock, convertible into 1,283,032 shares of AltaVista common stock. As of October 31, 2001, AltaVista owed Compaq approximately $3.1 million under the note, and Compaq has the right to provide AltaVista with additional convertible debt financing in the future based on the amount of funding provided by the Company and the percentage ownership of AltaVista by the Company and Compaq at the end of each quarter. Any future funding provided by Compaq is convertible into shares of Series A convertible preferred stock of AltaVista.

In August 1999, AltaVista and Compaq entered into a Customer Services Software Product Services Agreement. Compaq agreed to supply level 1 software support services to purchasers of AltaVista's software, and Compaq agreed to pay AltaVista a portion of the fees received for subscription services plus $50,000 per quarter for AltaVista's provision of level 2 and 3 support. From August 1, 2000 through October 31, 2001, AltaVista received approximately $250,000 under the agreement.

In November 1999, AltaVista entered into a Master Lease and Financing Agreement with Compaq Financial Services Corporation ("CFS"), a subsidiary of Compaq. Pursuant to the agreement, CFS may lease equipment and computer software programs to AltaVista and provide financing for license fees related to computer software programs and other services. As of October 31, 2001, AltaVista's outstanding balance under the agreement was approximately $19.8 million. In May 2000, AltaVista entered into an addendum to the Master Lease and Financing Agreement pursuant to which CFS has agreed to lease equipment and computer software programs to AltaVista in the United Kingdom. As of October 31, 2001, AltaVista's outstanding balance under the addendum was approximately $5.1 million. On November 8, 2001, AltaVista purchased certain equipment, which AltaVista previously leased from CFS under the Master Lease and Financing Agreement, for $20 million in cash.

In December 1999, AltaVista and Compaq entered into a Business Partner Agreement pursuant to which Compaq agreed to resell AltaVista's search technology. From August 1, 2000 through October 31, 2001, AltaVista received approximately $1.7 million under the agreement.

The Company has entered into a Master Lease and Financing Agreement with CFS, pursuant to which CFS may lease equipment and computer software programs to the Company and provide financing for license fees related to computer software programs and other services. As of October 31, 2001, the Company's outstanding balance under the agreement was approximately $9.2 million.

In June 2000, the Company acquired an approximate 33% ownership interest in B2E Solutions LLC ("B2E"), a joint venture with Compaq. In fiscal 2001, the Company's ownership interest in B2E increased to approximately 49% when, in a series of transactions pursuant to the terms of the acquisition agreement, the Company, among other things, (i) issued and sold an aggregate of 98,536 shares of its Common Stock to Compaq for an aggregate purchase price of $7.0 million and (ii) paid an aggregate of $14.0 million to B2E for additional membership interests in B2E. During fiscal 2001, the Company made a capital contribution to B2E of

20

approximately $140,000. From August 1, 2000 through October 31, 2001, B2E purchased approximately $4.0 million of products and services from the Company.

Pursuant to a Software Distribution Agreement by and between Engage and Compaq, pursuant to which Compaq agreed to market and distribute certain software products and technology of Engage on a worldwide basis, Engage received approximately $16.1 million from August 1, 2000 through October 31, 2001.

NaviSite has entered into a Master Lease and Financing Agreement with CFS, pursuant to which CFS may lease equipment and computer software programs to NaviSite and provide financing for license fees related to computer software programs and other services. As of October 31, 2001, NaviSite's outstanding balance under the agreement was approximately $29.5 million. On November 8, 2001, NaviSite purchased certain equipment previously leased from CFS, by issuing a note payable in the face amount of approximately $35 million. CFS and the Company also loaned NaviSite $20 million and $10 million, respectively, in cash. In exchange for the cash infusion, NaviSite issued notes payable in the face amounts of $20 million and $10 million to CFS and the Company, respectively, making the total notes payable issued by NaviSite to CFS and the Company, approximately $55 million and $10 million, respectively. The notes require payment of interest only, at 12% per annum, for the first three years from the date of issuance and then repayment of interest and principal, on a straight-line basis, over the next three years until maturity on the sixth anniversary of the date of issuance. At NaviSite's option, it may make interest payments (i) 100% in shares of NaviSite common stock, in the case of amounts owed to the Company and (ii) approximately 16.67% in shares of NaviSite common stock through December 2003, in the case of amounts owed to CFS. Subject to NaviSite stockholder approval, the principal balance will be convertible into NaviSite common stock at the option of the holders at any time prior to or at maturity at a rate of $0.26 per share. If this conversion feature is exercised by CFS, the Company's ownership in NaviSite would drop below 50% and the Company would no longer consolidate NaviSite's financial results which currently represent a substantial portion of its Infrastructure and Enabling Technologies segment. The Company also converted its $80 million in aggregate principal amount of notes receivable from NaviSite, plus the accrued interest thereon, into approximately 14.8 million shares of NaviSite common stock. The Company also converted approximately $16.2 million in other amounts receivable from NaviSite into approximately 9.9 million shares of NaviSite common stock.

The graph shown above assumes that $100 was invested in the Company's Common Stock and in each index on July 31, 1996. In addition, the total returns for the Company's Common Stock and the indexes used assume the reinvestment of all dividends. On July 31, 1997, the Company paid a dividend of one share of the common stock of Lycos for every 64 shares of the Company's Common Stock held. The graph assumes that the Lycos common stock received as a dividend was sold on the date received and that the proceeds of such sale, as well as the proceeds for the fractional shares of Lycos, were used to purchase additional shares of the Company's Common Stock on July 31, 1997. Fractional shares of Lycos common stock were paid out on July 31, 1997 based upon the closing price of the Lycos common stock on June 5, 1997.

Employment Agreements and Severance and Change of Control Arrangements

The Company is a party to an Employment Agreement, dated as of November 9, 1993, as amended, with David S. Wetherell, providing for the employment of Mr. Wetherell as Chief Executive Officer of the Company. The agreement provides for a term of employment through July 31, 2003 and a minimum annual base salary that is currently $1. The agreement also provides for annual incentive awards in amounts to be determined by the Compensation Committee, participation in all benefits made available to senior executives generally and salary

22

continuation for the shorter of two years or the remaining term of the agreement in the event (i) Mr. Wetherell terminates his employment following a Change of Control of the Company (as defined), or (ii) Mr. Wetherell's employment is terminated by the Company other than for Cause (as defined); except that the two-year limit shall not apply in either event if the Company has achieved certain specified performance goals. The minimum annual base salary may be increased from time to time at the discretion of the Compensation Committee; provided that it may not thereafter be reduced without Mr. Wetherell's consent except as part of a general reduction in executive salaries. The agreement contains non-competition covenants in favor of the Company through July 31, 2005.

Pursuant to the employment agreement, on November 9, 1993, Mr. Wetherell was also granted a non-qualified stock option under the Company's 1986 Stock Option Plan to purchase 4,800,000 shares of common stock at an exercise price of $0.165 per share. The option becomes exercisable in ten annual installments of 480,000 shares each, beginning on November 1, 1994, and ending on November 1, 2003, but only if and to the extent that the Company meets certain performance goals as determined by the Compensation Committee. In any event, the option became exercisable (to the extent not previously exercisable) as to the first 2,400,000 shares on November 1, 1998, and becomes exercisable as to the second 2,400,000 shares on November 1, 2003. In the event Mr. Wetherell terminates his employment following a Change of Control of the Company, a percentage of all remaining installments of his stock option would become exercisable, equal to the percentage of installments that had previously become exercisable. In the event Mr. Wetherell's employment is terminated by the Company other than for Cause, a percentage of up to three remaining installments of his stock option would become exercisable, equal to the percentage of installments that had previously become exercisable.

Any compensation payable under the employment agreement to Mr. Wetherell contingent on a Change of Control of the Company which qualifies as a "parachute payment" under Section 280G of the Internal Revenue Code of 1986, as amended, shall be limited to the maximum amount that may be paid to him without any part of such compensation being deemed an excess parachute payment under the Code.

The Limited Liability Company Agreement of CMG@Ventures I, LLC provides that, upon a change of control (as defined), each profit member, including Mr. Wetherell, may elect, within two months of the date of the change of control, to have CMG@Ventures I, LLC repurchase all, and not less than all, of the interest in CMG@Ventures I, LLC held by such profit member at the fair market value of such interest as determined by an independent appraisal pursuant to a procedure set forth in the Limited Liability Company Agreement. A change of control is defined to mean, among other things, a change of control of the Company (i) which has not been approved by a majority of all of the members of the Board of Directors of the Company, or (ii) which has been approved by a majority of all the members of the Board of Directors of the Company but which has not been approved by a majority in interest of the profit members of CMG@Ventures I, LLC and which is likely by its terms to have a material adverse effect upon the business and prospects of CMG@Ventures I, LLC and which change of control in either event is of a nature that would be required to be reported in response to Items 6(e) or 14(i), (iv) or (v) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), provided that, in the case of a change of control reportable under Item 6(e), such change of control involves the acquisition by any "person" (as such term in used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act, but expressly excluding Mr. Wetherell) of beneficial ownership, directly or indirectly, of securities or interests in the Company which represent more than 30% of the combined voting power of the Company's outstanding securities.

The Operating Agreement of CMG@Ventures II, LLC provides that, upon a change of control (as defined), each managing member, including Mr. Wetherell, may elect, within two months of the date of the change of control, to have CMG@Ventures II, LLC repurchase all, and not less than all, of the interest in CMG@Ventures II, LLC held by such managing member at the fair market value of such interest as determined by an independent appraisal pursuant to a procedure set forth in the Operating Agreement. A change of control is defined to mean, among other things, a change of control of the Company (i) which has not been approved by a majority of all of the members of the Board of Directors of the Company, or (ii) which has been approved by a

23

majority of all the members of the Board of Directors of the Company but which has not been approved by a majority in interest of the members of CMG@Ventures II, LLC and which is likely by its terms to have a material adverse effect upon the business and prospects of CMG@Ventures II, LLC and which change of control in either event is of a nature that would be required to be reported in response to Items 6(e) or 14(i), (iv) or (v) of Schedule 14A of Regulation 14A promulgated under the Exchange Act, provided that, in the case of a change of control reportable under Item 6(e), such change of control involves the acquisition by any "person" (as such term in used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act, but expressly excluding Mr. Wetherell) of beneficial ownership, directly or indirectly, of securities or interests in the Company which represent more than 30% of the combined voting power of the Company's outstanding securities.

Mr. Andonian and the Company have entered into an Executive Retention Agreement, dated as of July 9, 2001, that provides in the event that his employment is terminated by the Company for a reason other than for Cause (as defined), then the Company shall pay Mr. Andonian a severance payment equal to his then-current annual base salary, payable in 24 semi-monthly installments, plus his target bonus as in effect on his last day of employment. In addition, the agreement provides that in the event that his employment is terminated by the Company for a reason other than for Cause or by Mr. Andonian for Good Reason (as defined) within one year following a Change of Control of the Company (as defined), then (i) the Company shall pay Mr. Andonian a one-time severance payment equal to two times his then-current annual base salary plus two times his then-current target bonus, and (ii) outstanding options to purchase an aggregate of 1,050,000 shares of Common Stock shall immediately become fully vested.

In connection with his resignation in September 2001, Engage agreed to continue to pay Mr. Nuzzo his regular base salary in semi-monthly installments of $11,666.67 each until November 19, 2002.

Annual Meeting of Stockholders CMGI, INC. December 19, 2001


APPENDIX II
CMGI, INC.

AMENDED AND RESTATED 1995 EMPLOYEE STOCK PURCHASE PLAN

1. Purpose. This 1995 Employee Stock Purchase Plan (as amended and restated, the "Plan") is intended to encourage and assist employees of CMGI, Inc. (the "Corporation") and the employees of any present or future designated subsidiaries of the Corporation in acquiring a stock ownership interest in the Corporation. The Plan is intended to be an Employee Stock Purchase Plan under, and complying with, the terms and conditions of Section 423 of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (the "Code").

2. Stock Subject to the Plan. Subject to adjustment pursuant to Section 12 of the Plan, the aggregate number of shares of Common Stock, $.01 par value per share, of the Corporation (the "Common Stock") which may be sold under this Plan pursuant to the exercise of non-transferable options granted under this Plan to participating employees is 56,000,000 (as adjusted through June 9, 2000), less such number of shares as may from time to time be issued pursuant to the Corporation's 1986 Stock Option Plan, as amended and/or restated from time to time. The shares may be authorized but unissued, or reacquired, shares of Common Stock. The Corporation during the term of the Plan shall at all times reserve and keep available such number of shares of Common Stock as shall be sufficient to satisfy the requirements of the Plan.

3. Quarterly Periods. As used herein, the term "quarterly period" shall mean the three-month period beginning on the first day of each of the Corporation's fiscal quarters and ending on the last day of each of the Corporation's fiscal quarters.

4. Eligibility. Any employee of the Corporation or any of its present or future designated subsidiaries (except (a) any employee who, immediately after the grant of an option hereunder, directly or by attribution owns stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Corporation or any subsidiary of the Corporation, or
(b) any employee whose customary employment is 20 hours or less per week, or
(c) any employee whose customary employment is for not more than five months in any calendar year) is eligible to participate in the Plan on the first day of the first quarterly period following commencement of employment. Any subsidiary of the Corporation, including future subsidiaries, may or may not be designated by the Board of Directors of the Corporation as a subsidiary whose employees may participate in the Plan as provided above.

For purposes of the Plan, "subsidiary" shall have the meaning set forth in
Section 424(f) of the Code.

5. Participation. Any eligible employee's participation in the Plan shall be effective as of the first day of the quarterly period following the day on which the employee completes, signs and returns to the Corporation a Stock Purchase Plan Application and Payroll Deduction Authorization form indicating his or her acceptance of and agreement to the terms and conditions of the Plan and indicating the employee's standing level of contribution to the Plan in accordance with Paragraph 6 below. Participation of any employee in the Plan is entirely voluntary. All eligible employees who elect to participate in the Plan shall have the same rights and privileges. Unless an employee files a new form or withdraws from the Plan, his or her deductions and purchases will continue at the same rate for future quarterly periods as long as the Plan remains in effect.

Any employee participating in the Plan or receiving shares of Common Stock hereunder shall have no rights with respect to continuation of employment with the Corporation or any subsidiary, nor with respect to continuation of any particular Corporation business, policy or product, including the Plan.

6. Deductions. Any employee electing to participate in the Plan must authorize a whole percentage (not less than 1% nor more than 10%) or a whole dollar amount (not less than $10.00) of the employee's regular pay to be deducted by the Corporation from the employee's regular pay during each quarterly period, provided that in no event may such percentage or amount result in total deductions of less than $100.00 per quarterly period for such employee.

1

Notwithstanding the foregoing, no employee shall be entitled to purchase shares of Common Stock under the Plan with an aggregate fair market value (determined at date of grant) exceeding $6,250 per quarterly period; and furthermore, no employee shall be permitted to purchase shares of common stock under all the employee stock purchase plans of the Corporation and its subsidiaries at a rate which exceeds $25,000 in fair market value of such stock (determined at the time the options are granted) per calendar year in which any such option granted to such employee is outstanding at any time.

An employee may elect to have amounts deducted from his or her pay, as described above, by delivering to the Corporation a Stock Purchase Plan Application and Payroll Deduction Authorization form stating the percentage or amount to be deducted. If an employee has not filed such a standing election prior to the commencement date of a quarterly period, he or she will be deemed to have elected not to have any of his or her pay withheld. Deductions may be increased or decreased during a quarterly period by filing a new standing election, which will be effective during the first full pay period subsequent to its filing and processing.

No employee will be permitted to make contributions for any period during which he or she is not receiving pay from the Corporation or one of its present or future designated subsidiaries.

7. Issuance of Shares. On the last trading day of each quarterly period so long as the Plan shall remain in effect, and provided the employee has not before that date advised the Corporation that he or she elects to withdraw his or her entire account, the Corporation shall apply the funds in the employee's account as of that date to the purchase of authorized but unissued, or reacquired, shares of Common Stock in units of one share or whole multiples thereof.

The cost to each employee for the shares of Common Stock so purchased shall be eighty-five percent (85%) of the lower of the fair market value of the Common Stock on the first trading day of the quarterly period (the "date of grant") and the fair market value of the Common Stock on the last trading day of the quarterly period (the "date of exercise"), determined as follows:

(1) The fair market value of the shares on the date of the grant shall be the mean between the average bid and ask prices of the stock in the over-the-counter market as quoted on the National Association of Securities Dealers Automatic Quotation System (NASDAQ), or if its stock is quoted on the Nasdaq National Market the last reported sales price of the stock, or if the stock is traded on one or more securities exchanges the average of the closing prices on all such exchanges on the date of grant; and

(2) The fair market value of the shares on the date of exercise shall be the mean between the average bid and ask prices of the stock in the over-the-counter market as quoted on the National Association of Securities Dealers Automatic Quotation System (NASDAQ), or if its stock is quoted on the Nasdaq National Market the last reported sales price of the stock, or if the stock is traded on one or more securities exchanges the average of the closing prices on all such exchanges on the date of exercise.

Any amount remaining in an employee's account at the end of a quarterly period after application to the purchase of shares of Common Stock shall be refunded to the employee, except that any amount remaining in an employee's account equal to less than the sum required to purchase one share shall, unless otherwise requested by the employee, be held in the employee's account for use during the next quarterly period. Any amount remaining in such employee's account by reason of his or her prior election to withdraw his or her entire account shall be disbursed to the employee within 30 days following such election. The Corporation shall as expeditiously as possible after the last day of each quarterly period issue to the employee entitled thereto the certificate evidencing the shares of Common Stock issuable to him or her as provided herein.

Notwithstanding anything above to the contrary, (a) if the aggregate number of shares of Common Stock employees desire to purchase at the end of any quarterly period exceeds the number of shares then available under the Plan, the shares available shall be allocated among such employees in proportion to their contributions during the quarterly period (but no fractional shares shall be issued); and (b) no funds in an employee's account shall be applied to the purchase of shares and no shares hereunder shall be issued unless such shares are covered by an effective registration statement under the Securities Act of 1933, as amended, or by an exemption therefrom.

2

8. Termination of Participation. An employee's participation in the Plan will be terminated when the employee (a) voluntarily elects to withdraw his or her entire account, (b) resigns or is discharged from the Corporation and all of its present or future designated subsidiaries or (c) dies. Upon termination of participation, the employee shall not be entitled to rejoin the Plan until the first day of the quarterly period immediately following the quarterly period in which the termination of participation occurs. Upon termination of participation, the employee shall be entitled to the amount of his or her individual account within thirty (30) days.

If, prior to the last day of the quarterly period, the designated subsidiary by which an employee is employed shall cease to be a subsidiary of the Corporation, or if the employee is transferred to a subsidiary of the Corporation that is not a designated subsidiary, the employee shall be deemed to have been discharged from the Corporation and all designated subsidiaries for purposes of the Plan.

9. Beneficiary. Each employee may file a written designation of a beneficiary who is to receive any shares of Common Stock credited to such employee's account under the Plan in the event of the death of such employee prior to delivery to such employee of the certificates for such shares. Such designation may be changed by the employee at any time by written notice received by the Corporation.

Upon the death of an employee, his or her account shall be paid or distributed to the beneficiary or beneficiaries designated by such employee, or in the absence of such designation, to the executor or administrator of his or her estate, and in either event the Corporation shall not be under any further liability to anyone. If more than one beneficiary is designated, each beneficiary shall receive an equal portion of the account unless the employee indicates to the contrary in his or her designation, provided that the Corporation may in its sole discretion make distributions in such form as will avoid the creation of fractional shares.

10. Administration of the Plan. The Plan shall be administered by the Compensation Committee of the Board of Directors of the Corporation. All terms of the Plan shall be subject to interpretation by the Compensation Committee of the Board of Directors whose decision shall be final and binding on all parties. All costs and expenses incurred in administering the Plan shall be paid by the Corporation.

11. Modification and Termination. The Corporation expects to continue the Plan until such time as the shares of Common Stock reserved for issuance under the Plan have been sold. The Corporation reserves, however, the right to amend, alter or terminate the Plan in its discretion. Upon termination of the Plan, each employee shall be entitled to the amount of his or her individual account within thirty (30) days after such termination.

12. Adjustments upon Changes in Capitalization; Change of Control. Appropriate and proportionate adjustments shall be made in the number and class of shares of stock subject to this Plan, and to the rights granted hereunder and the prices applicable to such rights, in the event of a stock dividend, stock split, reverse stock split, recapitalization, reorganization, merger, consolidation, acquisition, separation or other similar change in the capital structure of the Corporation.

If the Corporation shall at any time merge or consolidate with another corporation and the holders of the capital stock of the Corporation immediately prior to such merger or consolidation do not continue to hold at least 50% by voting power of the capital stock of the surviving corporation, or in the event of a sale of all or substantially all of the assets of the Corporation, all outstanding options under the Plan shall be deemed cancelled as of the effective date of any such transaction, provided that notice of such cancellation shall be given to each holder of an option, and each holder of an option shall have the right to exercise such option in full based on payroll deductions then credited to his account as of a date determined by the Board of Directors.

13. Transferability of Rights. No rights of any employee under this Plan shall be transferable by him or her, by operation of law or otherwise, except to the extent that an employee is permitted to designate a beneficiary or beneficiaries as herein above provided, and except to the extent permitted by will or the laws of descent and distribution if no such beneficiary be designated.

3

14. Participation in Other Plans. Nothing herein contained shall affect an employee's right to participate in and receive benefits under and in accordance with the then current provisions of any pension, insurance or other employee welfare plan or programs of the Corporation.

15. Applicable Law. The interpretation, performance and enforcement of this Plan shall be governed by the laws of the State of Delaware.

16. Notification upon Sale of Shares. Each employee agrees, by participating in the Plan, to promptly give the Corporation notice of any disposition of shares purchased under the Plan where such disposition occurs within two years after the date of grant of the option pursuant to which such shares were purchased or one year after the date of exercise of the option.

17. Effective Date of Plan; Governmental Regulation. The Plan was effective on February 1, 1995. The Plan was amended and restated on June 9, 2000, effective August 1, 2000. The Corporation's obligation to offer, sell or deliver shares of Common Stock under the Plan is subject to any governmental approval required in connection with the authorized issuance or sale of such shares and is further subject to the determination by the Corporation that is has complied with all applicable securities laws.
