Item 5: Other Events

On September 20, 1999, AdForce, Inc. (the "Company"), CMGI, Inc. ("CMGI") and
Artichoke Corp. ("Merger Sub") entered into a definitive Agreement and Plan of
Merger (the "Merger Agreement"). Pursuant to the Merger Agreement and subject to
the terms and conditions set forth therein, the Merger Sub will be merged with
and into the Company (the "Merger"), with the Company surviving the Merger and
becoming a wholly-owned subsidiary of CMGI. At the effective time of the Merger,
each outstanding share of the Company's common stock will be exchanged and
converted into 0.262 share of CMGI's common stock, and options and warrants to
purchase shares of the Company's common stock will be assumed and become options
and warrants, as applicable, to purchase shares of CMGI's common stock. The
exercise price and number of shares of the Company's common stock subject to
each such assumed option and warrant will be appropriately adjusted to reflect
the exchange ratio. The transaction is intended to qualify as a tax-free
reorganization and will be accounted for as a purchase.

In connection with the execution of the Merger Agreement, the Company and CMGI
entered into a Stock Option Agreement (the "Stock Option Agreement"), pursuant
to which the Company granted to CMGI an option to purchase up to 19.9% of the
outstanding shares of the Company's common stock; the option is exercisable upon
the occurrence of certain events specified in the Stock Option Agreement.
Stockholders of the Company holding approximately 37.2% of the Company's
outstanding common stock have agreed to vote in favor of the Merger at the
Company's stockholder meeting called for such purpose. A form of Stockholder
Agreement and Irrevocable Proxy is included in this report as Exhibit 4.1.

A copy of the Merger Agreement and a copy of the Stock Option Agreement are
included in this report as Exhibit 2.1 and 2.2, respectively. The foregoing
description is qualified in its entirety by reference to the full text of such
exhibits. A joint press release announcing these transactions is attached to
this report as Exhibit 99.1. The Merger is subject to various conditions,
including clearance under the Hart-Scott-Rodino Antitrust Improvements Act and
approval of the Company's stockholders.

                            AGREEMENT AND PLAN OF MERGER


       THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of
September 20, 1999, is by and among CMGI, Inc., a Delaware corporation (the
"Buyer"), Artichoke Corp., a Delaware corporation and a wholly owned subsidiary
of Buyer (the "Transitory Subsidiary"), and AdForce, Inc., a Delaware
corporation (the "Company").

       WHEREAS, the Boards of Directors of the Buyer and the Company deem it
advisable and in the best interests of each corporation and its respective
stockholders that the Buyer and the Company combine in order to advance the
long-term business interests of the Buyer and the Company;

       WHEREAS, the combination of the Buyer and the Company shall be effected
by the terms of this Agreement through a merger of the Transitory Subsidiary
into the Company, as a result of which the stockholders of the Company will
become stockholders of the Buyer (the "Merger");

       WHEREAS, concurrently with the execution and delivery of this Agreement
and as a condition and inducement to the Buyer's willingness to enter into this
Agreement, certain employees and stockholders of the Company have entered into
Stock Lock-Up Agreements dated as of the date of this Agreement and attached
hereto as EXHIBIT A-1 and A-2, respectively (collectively, the "Lock-Up
Agreements"), pursuant to which such parties have agreed to certain restrictions
relating to the disposition of Buyer Common Stock following the Effective Time
(as defined in Section 1.1) under certain circumstances;

       WHEREAS, concurrently with the execution and delivery of this Agreement
and as a condition and inducement to the Buyer's willingness to enter into this
Agreement, the stockholders of the Company specified in Section 6.5(c) of this
Agreement have entered into a Stockholder Agreement dated as of the date of this
Agreement in the form attached as EXHIBIT B (the "Stockholder Agreement"),
pursuant to which such stockholders agreed to give the Buyer a proxy to vote all
of the shares of capital stock of the Company that such stockholders own; and

       WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of  the
Internal Revenue Code of 1986, as amended (the "Code").

       NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
Buyer, the Transitory Subsidiary and the Company agree as follows:


                                     ARTICLE I
                                     THE MERGER

       1.1    EFFECTIVE TIME OF THE MERGER .  Subject to the provisions of this
Agreement, prior to the Closing (as defined in Section 1.2), the Buyer shall
prepare, and on the Closing Date (as defined in Section 1.2) or as soon as
practicable thereafter the Buyer shall cause to be filed with the Secretary of
State of the State of Delaware, a certificate of merger (the "Certificate of
Merger") in such form as is required by, and executed by the Surviving
Corporation (as defined in Section 1.3) in accordance with, the relevant
provisions of the Delaware General Corporation Law ("DGCL") and shall make all
other filings or recordings required under the DGCL.  The Merger shall become
effective upon the filing of the Certificate of Merger with the Secretary of
State of the State of Delaware or at such later time as is established by the
Buyer and the Company and set forth in the Certificate of Merger (the "Effective
Time").

       1.2    CLOSING .  The closing of the Merger (the "Closing") shall take
place at 10:00 a.m., Boston time, on a date to be specified by the Buyer and the
Company (the "Closing Date"), which shall be no later than the second business
day after satisfaction or waiver of the conditions set forth in Article VII
(other than delivery of items to be delivered at the Closing), at the offices of
Hale and Dorr LLP, 60 State Street, Boston, Massachusetts,

<PAGE>

unless another date, place or time is agreed to in writing by the Buyer and
the Company.

       1.3    EFFECTS OF THE MERGER .  At the Effective Time (i) the separate
existence of the Transitory Subsidiary shall cease and the Transitory Subsidiary
shall be merged with and into the Company (the Transitory Subsidiary and the
Company are sometimes referred to below as the "Constituent Corporations" and
the Company following the Merger is sometimes referred to below as the
"Surviving Corporation"), (ii) the Certificate of Incorporation of the Company
shall be amended so that Article FOURTH of such Certificate of Incorporation
reads in its entirety as follows:  "The total number of shares of all classes of
stock which the Corporation shall have authority to issue is 1,000, all of which
shall consist of common stock, $.01 par value per share," and, as so amended,
such Certificate of Incorporation shall be the Certificate of Incorporation of
the Surviving Corporation, and (iii) the By-laws of the Transitory Subsidiary as
in effect immediately prior to the Effective Time shall be the By-laws of the
Surviving Corporation.  The Merger shall have the effects set forth in Section
259 of the DGCL.

       1.4    DIRECTORS AND OFFICERS .  The directors and officers of the
Transitory Subsidiary immediately prior to the Effective Time shall be the
initial directors and officers of the Surviving Corporation, each to hold office
in accordance with the Certificate of Incorporation and By-laws of the Surviving
Corporation.

                                     ARTICLE II
                              CONVERSION OF SECURITIES

       2.1    CONVERSION OF CAPITAL STOCK .  As of the Effective Time, by virtue
of the Merger and without any action on the part of the holder of any shares of
the capital stock of the Company or capital stock of the Transitory Subsidiary:

              (a)    CAPITAL STOCK OF THE TRANSITORY SUBSIDIARY.  Each issued
and outstanding share of the capital stock of the Transitory Subsidiary shall be
converted into and become one fully paid and nonassessable share of common
stock, $.01 par value per share, of the Surviving Corporation.

              (b)    CANCELLATION OF TREASURY STOCK AND BUYER-OWNED STOCK.  All
shares of common stock, $.001 par value per share, of the Company ("Company
Common Stock") that are owned by the Company as treasury stock or by any wholly
owned Subsidiary (as defined in Section 3.1) of the Company and any shares of
Company Common Stock owned by the Buyer, the Transitory Subsidiary or any other
wholly owned Subsidiary of the Buyer shall be cancelled and retired and shall
cease to exist and no stock of the Buyer or other consideration shall be
delivered in exchange therefor.

              (c)    EXCHANGE RATIO FOR COMPANY COMMON STOCK.  Subject to
Section 2.2, each share of Company Common Stock (other than shares to be
cancelled in accordance with Section 2.1(b)) issued and outstanding immediately
before the Effective Time, and all rights in respect thereof, shall be
automatically converted into 0.262 shares (the "Exchange Ratio ") of common
stock, $.01 par value per share, of the Buyer ("Buyer Common Stock").  As of the
Effective Time, all such shares of Company Common Stock shall no longer be
outstanding and shall automatically be cancelled and retired and shall cease to
exist, and each holder of a certificate representing any such shares of Company
Common Stock shall cease to have any rights with respect thereto, except the
right to receive the shares of Buyer Common Stock and any cash in lieu of
fractional shares of Buyer Common Stock to be issued or paid in consideration
therefor upon surrender of such certificate in accordance with Section 2.2,
without interest.

              (d)    ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Buyer Common Stock or Company Common Stock), reorganization, recapitalization or
other like change with respect to Buyer Common Stock or Company Common Stock
occurring after the date hereof and prior to the Effective Time.

              (e)    UNVESTED STOCK.  At the Effective Time, any unvested shares
of Company Common Stock awarded to employees, directors or consultants pursuant
to any of the Company's plans or arrangements and

<PAGE>

outstanding immediately prior to the Effective Time shall be converted to
unvested shares of Buyer Common Stock in accordance with the Exchange Ratio
and shall remain subject to the same terms, restrictions and vesting schedule
as in effect immediately prior to the Effective Time, except to the extent by
their terms such unvested shares of Company Common Stock vest at the
Effective Time and copies of the relevant agreements governing such vesting
had been provided to Buyer.  All outstanding rights which the Company may
hold immediately prior to the Effective Time to repurchase unvested shares of
Company Common Stock shall be assigned to the Buyer in the Merger and shall
thereafter be exercisable by the Buyer upon the same terms and conditions in
effect immediately prior to the Effective Time, except that the shares
purchasable pursuant to such rights and the purchase price payable per share
shall be adjusted to reflect the Exchange Ratio.

              (f)    TREATMENT OF COMPANY OPTIONS AND COMPANY WARRANTS.
Outstanding Company Options and Company Warrants (in each case as defined in
Section 3.2(b)) shall be treated following the Effective Time in the manner set
forth in Section 6.11.

       2.2    EXCHANGE OF CERTIFICATES .  The procedures for exchanging
outstanding shares of Company Common Stock for Buyer Common Stock pursuant to
the Merger are as follows:

              (a)    EXCHANGE AGENT.  As of the Effective Time, the Buyer shall
deposit with a bank or trust company designated by the Buyer (the "Exchange
Agent"), for the benefit of the holders of shares of the Company Common Stock,
for exchange in accordance with this Section 2.2, through the Exchange Agent,
(i) certificates representing the shares of Buyer Common Stock (such shares of
Buyer Common Stock, together with any dividends or distributions with respect
thereto, being hereinafter referred to as the "Exchange Fund") issuable pursuant
to Section 2.1 in exchange for outstanding shares of the Company Common Stock,
(ii) cash in an amount sufficient to make payments required pursuant to Section
2.2(e), and (iii) any dividends or distributions to which holders of
Certificates (as defined below) may be entitled pursuant to Section 2.2(c)

              (b)    EXCHANGE PROCEDURES.  As soon as reasonably practicable
after the Effective Time, the Exchange Agent shall mail to each holder of record
of a certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of the Company Common Stock (the "Certificates")
whose shares were converted pursuant to Section 2.1 into the right to receive
shares of Buyer Common Stock (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon delivery of the Certificates to the Exchange Agent and
shall be in such form and have such other provisions as the Buyer may reasonably
specify) and (ii) instructions for effecting the surrender of the Certificates
in exchange for certificates representing shares of Buyer Common Stock (plus
cash in lieu of fractional shares, if any, of Buyer Common Stock and any
dividends or distributions as provided below).  Upon surrender of a Certificate
for cancellation to the Exchange Agent or to such other agent or agents as may
be appointed by the Buyer, together with such letter of transmittal, duly
executed, and such other documents as may reasonably be required by the Exchange
Agent, the holder of such Certificate shall be entitled to receive in exchange
therefor a certificate representing that number of whole shares of Buyer Common
Stock which such holder has the right to receive pursuant to the provisions of
this Article II plus cash in lieu of fractional shares pursuant to
Section 2.2(e) and any dividends or distributions pursuant to Section 2.2(c),
and the Certificate so surrendered shall immediately be cancelled.  In the event
of a transfer of ownership of Company Common Stock which is not registered in
the transfer records of the Company, a certificate representing the proper
number of shares of Buyer Common Stock plus cash in lieu of fractional shares
pursuant to Section 2.2(e) and any dividends or distributions pursuant to
Section 2.2(c) may be issued and paid to a person other than the person in whose
name the Certificate so surrender is registered, if such Certificate is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid.  Until surrendered as contemplated by this
Section 2.2, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the certificate
representing shares of Buyer Common Stock plus cash in lieu of fractional shares
pursuant to Section 2.2(e) and any dividends or distributions pursuant to
Section 2.2(c) as contemplated by this Section 2.2.

              (c)    DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No
dividends or other distributions declared or made after the Effective Time with
respect to Buyer Common Stock with a record date after the

<PAGE>

Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of Buyer Common Stock represented thereby and no
cash payment in lieu of fractional shares shall be paid to any such holder
pursuant to Section 2.2(e) until the holder of record of such Certificate
shall surrender such Certificate. Subject to the effect of applicable laws,
following surrender of any such Certificate, there shall be issued and paid
to the record holder of the Certificate, (i) certificates representing whole
shares of Buyer Common Stock issued in exchange therefor, without interest,
(ii) at the time of such surrender, the amount of any cash payable in lieu of
a fractional share of Buyer Common Stock to which such holder is entitled
pursuant to Section 2.2(e) and the amount of dividends or other distributions
with a record date after the Effective Time previously paid with respect to
such whole shares of Buyer Common Stock, and (iii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of Buyer Common Stock.

              (d)    NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All
shares of Buyer Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms hereof (including any cash or other
distributions paid pursuant to Sections 2.2(c) or 2.2(e)) shall be deemed to
have been issued in full satisfaction of all rights pertaining to such shares of
Company Common Stock, and from and after the Effective Time there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock which were outstanding
immediately prior to the Effective Time.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation or the Exchange Agent
for any reason, they shall be cancelled and exchanged as provided in this
Article II.

              (e)    NO FRACTIONAL SHARES.  No certificate or scrip representing
fractional shares of Buyer Common Stock shall be issued upon the surrender for
exchange of Certificates, and such fractional share interests will not entitle
the owner thereof to vote or to any other rights of a stockholder of the Buyer.
Notwithstanding any other provision of this Agreement, each holder of shares of
Company Common Stock exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of Buyer Common Stock (after
taking into account all Certificates delivered by such holder) shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of Buyer Common Stock multiplied by the average of the last reported
sales prices of the Buyer Common Stock on the Nasdaq National Market during the
ten (10) consecutive trading days ending on and including the last trading day
prior to the Effective Time.

              (f)    TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange
Fund which remains undistributed to the holders of Company Common Stock for 180
days after the Effective Time shall be delivered to the Buyer, upon demand, and
any holder of Company Common Stock who has not previously complied with this
Section 2.2 shall thereafter look only to the Buyer for payment of its claim for
Buyer Common Stock, any cash in lieu of fractional shares of Buyer Common Stock
and any dividends or distributions with respect to Buyer Common Stock.

              (g)    NO LIABILITY.  To the extent permitted by applicable law,
none of the Buyer, the Transitory Subsidiary, the Company, the Surviving
Corporation or the Exchange Agent shall be liable to any holder of shares of
Company Common Stock or Buyer Common Stock, as the case may be, for such shares
(or dividends or distributions with respect thereto) delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
If any Certificate shall not have been surrendered prior to one year after the
Effective Time (or immediately prior to such earlier date on which any shares of
Buyer Common Stock, and any cash payable to the holder of such Certificate
pursuant to this Article II or any dividends or distributions payable to the
holder of such Certificate would otherwise escheat to or become the property of
any Governmental Entity (as defined in Section 3.3(c))), any such shares of
Buyer Common Stock or cash, dividends or distributions in respect of such
Certificate shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interest
of any person previously entitled thereto.

              (h)    WITHHOLDING RIGHTS.  Each of the Buyer and the Surviving
Corporation shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of shares of Company
Common Stock such amounts as it is required to deduct and withhold with respect
to the making of such payment under the Code, or any other applicable provision
of law.  To the extent that amounts are so withheld

<PAGE>

by the Surviving Corporation or the Buyer, as the case may be, such withheld
amounts shall be treated for all purposes of this Agreement as having been
paid to the holder of the shares of Company Common Stock in respect of which
such deduction and withholding was made by the Surviving Corporation or the

misleading.  No Subsidiary of the Company is required to file any forms, reports
or other documents with the SEC.

Company as of June 30, 1999 is referred to herein as the "Company Balance
Sheet."

       3.5    NO UNDISCLOSED LIABILITIES .  Except as disclosed in the Company

Company SEC Reports filed prior to the date of this Agreement, since the date of
the Company Balance Sheet, the Company and its Subsidiaries have conducted their

Material Adverse Effect.  The Company and each of its Subsidiaries has paid on a
timely basis all Taxes (as defined below) that are shown to be due on any such
Tax Returns.  The unpaid Taxes of the Company and its Subsidiaries for Tax

imposed by the United States of America or any state, local or foreign
government, or any agency thereof, or other political subdivision of the United
States or any such government, and any interest, fines, penalties, assessments
or additions to tax resulting from, attributable to or incurred in connection
with any tax or any contest or dispute thereof and (ii) "Tax Returns" means all
reports, returns, declarations, statements or other information required to be
supplied to a taxing authority in connection with Taxes.

deficiencies assessed against or agreed to by the Company or any of its
Subsidiaries since inception.  The federal income Tax Returns of the Company and
each of its Subsidiaries have been audited by the Internal Revenue Service or

through the taxable year specified in Section 3.7(b) of the Company Disclosure
Schedule.  The Company has made available to the Buyer correct and complete
copies of all other Tax Returns of the Company and its Subsidiaries together
with all related examination reports and statements of deficiency for all
periods from and after January 1, 1997.  No examination or audit of any Tax
Return of the Company or any of its Subsidiaries by any Governmental Entity is
currently in progress or, to the knowledge of the Company, threatened or
contemplated.  Neither the Company nor any of its Subsidiaries has been informed
by any Governmental Entity that the Governmental Entity believes that the
Company or any of its Subsidiaries was required to file any Tax Return that was
not filed.  Neither the Company nor any of its Subsidiaries has waived any
statute of limitations with respect to Taxes or agreed to an extension of time
with respect to a Tax assessment or deficiency.

applications and tangible or intangible proprietary information or material that
are used or necessary to conduct the business of the Company and its
Subsidiaries as currently conducted (the "Company Intellectual Property

              (b)    The execution and delivery of this Agreement and
consummation of the Merger will not result in the breach of, or create on behalf
of any third party the right to terminate or modify, any material license,

and its Subsidiaries, taken as a whole, and to maintain in confidence all trade

required contributions thereto (or reserved for such contributions on the
Company Balance Sheet).  With respect to the Company Employee Plans, no event
has occurred, and to the knowledge of the Company, there exists no condition or
set of circumstances in connection with which the Company or any of its
Subsidiaries could be subject to any liability under ERISA, the Code or any
other applicable law which, individually or in the aggregate, is reasonably
likely to have a Company Material Adverse Effect.

unilaterally by the Company at any time without liability to the Company as a

summary plan description or other written communication distributed generally to
employees by its terms prohibits the Company from amending or terminating any
such Company Benefit Plan.

or plan binding the Company or any of its Subsidiaries, including any stock
option plan, stock appreciation right plan, restricted stock plan, stock
purchase plan or severance benefit plan, any of the benefits of which will be

information and documents as the Buyer shall reasonably request for purposes of
reviewing such list and shall notify the Buyer in writing regarding any change
in the identity of its Affiliates prior to the Closing Date.  The Company shall
use its reasonable efforts to deliver or cause to be delivered to the Buyer
prior to the

<PAGE>

mailing of the Proxy Statement from each of its Affiliates, an executed
Affiliate Agreement, in substantially the form appended hereto as EXHIBIT C
(the "Affiliate Agreement").  The Buyer shall be entitled to place
appropriate legends on the certificates evidencing any shares of Buyer Common
Stock to be received by Rule 145 Affiliates of the Company pursuant to the
terms of this Agreement, and to issue appropriate stop transfer instructions
to the transfer agent for the Buyer Common Stock (provided that such legends
or stop transfer instructions shall be removed, two years after the Effective
Date, upon the request of any stockholder that is not then an Affiliate of
the Buyer).

       6.10   NASDAQ NATIONAL MARKET LISTING .  The Buyer shall use its best
efforts to cause the shares of Buyer Common Stock issued pursuant to Section
2.1(c) and upon exercise of Company Stock Options and Company Warrants assumed
pursuant to Section 6.11 to be quoted on the Nasdaq National Market or listed on
such securities exchange on which the Buyer Common Stock is then listed.

       6.11   COMPANY STOCK PLANS AND THE COMPANY WARRANTS .

              (a)    At the Effective Time, each outstanding Company Stock
Option, whether vested or unvested, shall be assumed by Buyer and deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under the Company Stock Option immediately prior to the Effective
Time (including, if applicable, status as an "incentive stock option" under the
Code), the same number of shares of Buyer Common Stock as the holder of the
Company Stock Option would have been entitled to receive pursuant to the Merger
had such holder exercised such option in full immediately prior to the Effective
Time (rounded down to the nearest whole number), at a price per share (rounded
up to the nearest whole cent) equal to (y) the aggregate exercise price for the
shares of Company Common Stock purchasable pursuant to the Company Stock Option
immediately prior to the Effective Time divided by (z) the number of full shares
of Buyer Common Stock deemed purchasable pursuant to the Company Stock Option in
accordance with the foregoing.  Continuous employment with Company or its
subsidiaries shall be credited to the optionee for purposes of determining the
vesting of all assumed Company Options after the Effective Time.

              (b)    As soon as practicable after the Effective Time, the Buyer
shall deliver to the participants in the Company Stock Plans appropriate notice
setting forth such participants' rights pursuant thereto and the grants pursuant
to the Company Stock Plans shall continue in effect on the same terms and
conditions (subject to the adjustments required by this Section after giving
effect to the Merger).

              (c)    The Buyer shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Buyer Common Stock for
delivery upon exercise of the Company Stock Options assumed in accordance with
this Section.  As soon as practicable after the Effective Time, the Buyer shall
file a registration statement on Form S-8 (or any successor form) with respect
to the shares of Buyer Common Stock subject to such options and shall use its
best efforts to maintain the effectiveness of such registration statement or
registration statements (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such options remain outstanding.

              (d)    The Board of Directors of the Company shall, prior to or as
of the Effective Time, take all necessary actions, pursuant to and in accordance
with the terms of Company Stock Plans and the instruments evidencing the Company
Stock Options, to provide for the conversion of the Company Stock Options into
options to acquire Buyer Common Stock in accordance with this Section 6.11.

              (e)    Each outstanding purchase right under the Company's 1999
Employee Stock Purchase Plan (the "ESPP") (each an "Assumed Purchase Right")
shall be assumed by Buyer.  Each Assumed Purchase Right shall continue to have,
and be subject to, the terms and conditions set forth in the Company ESPP and
the documents governing the Assumed Purchase Rights, except that the number of
shares of Buyer Common Stock issuable upon exercise thereof shall equal the
number of shares of Company Common Stock otherwise issuable upon exercise
thereof multiplied by the Exchange Ratio and the purchase price of such shares
of Buyer Common Stock on the Purchase Date (as defined in the ESPP) shall be the
lower of (i) the quotient determined by dividing eighty-five (85%) of the fair
market value per share of the Company Common Stock on the Offering Date for such
Purchase Period by the Exchange Ratio or (ii) eighty-five (85%) of the fair
market value per share of the Buyer

<PAGE>

Common Stock on the applicable Purchase Date (with the number of shares
rounded down to the nearest whole share and the purchase price rounded up to
the nearest whole cent).  The Assumed Purchase Rights shall be exercised on
the applicable Purchase Date, and each participant shall, accordingly, be
issued shares of Buyer Common Stock at such time.  The Company ESPP and all
outstanding purchase rights thereunder shall terminate on the last day of any
Offering Period in effect on the date hereof, and no additional purchase
rights shall be granted and no additional Offering Periods shall commence
following the date hereof.  Buyer agrees that from and after the Effective
Time, employees of Company may participate in Buyer's employee stock purchase
plan, subject to the terms and conditions of such plan if they are not
participating in the ESPP on such date.  Capitalized terms in this Section
6.14 if not otherwise defined in this Agreement, have the meanings ascribed
to them in the Company ESPP.

       (f)    At the Effective Time, each outstanding Company Warrant shall be
assumed by Buyer and deemed to constitute a warrant to acquire, on the same
terms and conditions as where applicable under the Company Warrant immediately
prior to the Effective Time, the same number of shares of Buyer Common Stock as
the holder of the Company Warrant would have been entitled to receive pursuant
to the Merger had such holder exercised such warrant in full immediately prior
to the Effective Time (rounded down to the nearest whole number), at a price per
share (rounded up to the nearest whole cent) equal to (y) the aggregate warrant
exercise price for the shares of Company Common Stock purchasable pursuant to
the Company Warrant immediately prior to the Effective Time, divided by (z) the
number of full shares of Buyer Common Stock deemed purchasable pursuant to the
Company Warrant in accordance with the forgoing.

       6.12   STOCKHOLDER LITIGATION .  Until the earlier of the termination of
this Agreement in accordance with its terms or the Effective Time, the Company
shall give the Buyer the opportunity to participate at its expense in the
defense or settlement of any stockholder litigation against the Company or its
Board of Directors relating to this Agreement or any of the transactions
contemplated by this Agreement, and shall not settle any such litigation without
the Buyer's prior written consent, which will not be unreasonably withheld or
delayed.

       6.13   INDEMNIFICATION .  From and after the Effective Time, the Buyer
shall, to the fullest extent permitted by law, cause the Surviving Corporation,
for a period of six years from the Effective Time, to honor all of the Company's
obligations to indemnify and hold harmless each present and former director and
officer of the Company (the "Indemnified Parties"), against any costs or
expenses (including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities or amounts paid in settlement incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of or pertaining to matters
existing or occurring at or prior to the Effective Time, whether asserted or
claimed prior to, at or after the Effective Time, to the extent that such
obligations to indemnify and hold harmless exist on the date of this Agreement.

       6.14   NOTIFICATION OF CERTAIN MATTERS .  The Buyer will give prompt
notice to the Company, and the Company will give prompt notice to the Buyer, of
the occurrence, or failure to occur, of any event, which occurrence or failure
to occur would be reasonably likely to cause (a) (i) any representation or
warranty of such party contained in this Agreement that is qualified as to
materiality to be untrue or inaccurate in any respect or (ii) any other
representation or warranty of such party contained in this Agreement to be
untrue or inaccurate in any material respect, in each case at any time from and
after the date of this Agreement until the earlier of the termination of this
Agreement in accordance with its terms or the Effective Time, or (b) any
material failure of the Buyer and the Transitory Subsidiary or the Company, as
the case may be, or of any officer, director, employee or agent thereof, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement.  Notwithstanding the above, the
delivery of any notice pursuant to this Section will not limit or otherwise
affect the remedies available hereunder to the party receiving such notice or
the conditions to such party's obligation to consummate the Merger.

       6.15   EMPLOYEES .  The Buyer will have no obligation to retain any
employee or group of employees of the Company following the Effective Time.  As
soon as practicable after the execution of this Agreement, the Company and the
Buyer shall confer and work together in good faith to agree upon mutually
acceptable employee benefit and compensation arrangements (and terminate Company
employee plans immediately prior to the Effective Time, if appropriate) so as to
provide benefits to Company employees initially upon the Merger which are
generally equivalent to those being provided to employees of Company immediately
preceding the Effective Time, as well as

<PAGE>

to determine appropriate termination benefits for Company employees generally
and certain members of Company management in particular, in addition to any
and all severance, separation, retention and salary continuation plans,
programs or arrangements disclosed on the Company Disclosure Schedule.
Continuous employment with the Company or its subsidiaries shall be credited
to Company employees who become Buyer employees for all purposes of
eligibility and vesting of benefits, but not for purposes of accrual of
benefits.  Following the Effective Time, Buyer will enforce, and cause the
Company to enforce, the terms of the Retention and Severance Plan (as defined
in the Company Disclosure Schedule).

written notice by the terminating party to the other party), whether before or
after approval of the Merger by the stockholders of the Company:

              (a)    by mutual written consent of the Buyer and the Company; or

              (b)    by either the Buyer or the Company if the Merger shall not
have been consummated by April 30, 2000 (the "Outside Date") (provided that the
right to terminate this Agreement under this Section 8.1(b) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been a principal cause of or resulted in the failure of the Merger
to occur on or before such date); or

              (c)    by either the Buyer or the Company if a Governmental Entity
of competent jurisdiction shall have issued a nonappealable final order, decree
or ruling or taken any other nonappealable final action, in each case having the
effect of permanently restraining, enjoining or otherwise prohibiting the
Merger; or

              (d)    by either the Buyer or the Company if at the Company
Meeting (including any adjournment or postponement), the requisite vote of the
stockholders of the Company in favor of the Company Voting Proposal shall not
have been obtained (provided that the right to terminate this Agreement under
this Section 8.1(d) shall not be available to any party seeking termination who
at the time is in breach of or has failed to fulfill its obligations under this
Agreement); or

              (e)    by the Buyer, if: (i) the Board of Directors of the Company
shall have failed to recommend approval of the Company Voting Proposal in the
Proxy Statement or shall have withdrawn or modified its recommendation of the

exchange offer, fails to recommend against acceptance of such offer or takes no
position with respect to the acceptance thereof; or (v) for any reason the
Company fails to call and hold the Company Meeting by the date which is one
business day prior to the Outside Date (other than by reason of the Registration
Statement not being declared effective by the SEC sufficiently in advance of the
Outside Date in order to permit the holding of the Company Meeting); or

              (f)    by either the Buyer or the Company, if there has been a

Company, the Transitory Subsidiary or their respective officers, directors,
stockholders or Affiliates, except as set forth in Sections 3.29, 5.3, 8.3 and
Article IX; provided that any such termination shall not relieve any party from
liability for any willful breach of this Agreement (which includes without
limitation the making of any representation or warranty by a party in this
Agreement that the party knew was not true and accurate when made), and Sections
3.29, 5.3, 8.3 and Article IX of this Agreement and the Confidentiality

consummated; provided however, that the Company and the Buyer shall share
equally all fees and expenses, other than attorneys', accountants' and filing
fees, incurred with respect to the printing and filing of the Proxy Statement
(including any related preliminary materials) and the Registration Statement
and any amendments or supplements thereto.

              (b)    The Company shall pay the Buyer up to $500,000 as

       If a Termination Fee is paid or payable by the Company and, within six
(6) months of the date of termination of this Agreement, an Alternative
Transaction is consummated or the Company enters into an agreement with respect
thereto (a "Topping Transaction"), then the Company shall pay to the Buyer upon
the closing of the Topping Transaction a fee (the "Topping Fee") equal to five
percent (5%) of the total consideration paid in the Topping Transaction less an
amount equal to any Termination Fee actually paid to Buyer.  For purposes of
determining the Termination Fee, the value of any securities issued or issuable
as consideration in the Topping Transaction shall be measured by reference to
the closing price of such securities on the date of closing of the Topping
Transaction.

              (d)    The Buyer shall pay the Company up to $500,000 as
reimbursement for expenses of the Company actually incurred relating to the
transactions contemplated by this Agreement prior to termination (including, but
not limited to, but excluding any discretionary fees paid to such financial
advisors), upon the termination of this Agreement by the Company pursuant to (i)
Section 8.1(b) as a result of the failure to satisfy the condition set forth in

Section 8.3(b), 8.3(c), 8.3(d) and 8.3(e) shall be paid within one business day
after demand therefor following the first to occur of the events giving rise to
the payment obligation described in Section 8.3(b), 8.3(c)(i), (ii) or (iii),
8.3(d) or 8.3(e).  If one party fails to promptly pay to the other any expense
reimbursement or fee due hereunder, the defaulting party shall pay the costs and
expenses (including legal fees and expenses) in connection with any action,
including the filing of any lawsuit or other legal action, taken to collect
payment, together with interest on the amount of any unpaid fee at the publicly
announced prime rate of Fleet Bank, N.A. plus five percent per annum, compounded
quarterly, from the date such expense reimbursement or fee was required to be
paid.

              (g)    As used in this Agreement, "Alternative Transaction" means

value of all the assets of the Company immediately prior to such transaction,
or (iv) any public announcement by a Third Party of a proposal, plan or
intention to do any of the foregoing or any agreement to engage in any of the
foregoing.

by action taken or authorized by their respective Boards of Directors, at any
time before or after approval of the matters presented in connection with the
Merger by the stockholders of the Company, but, after any such approval, no
amendment shall be made which by law requires further approval by such
stockholders without such further approval.  This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

Any party may give any notice or other communication hereunder using any other
means (including personal delivery, messenger service, telecopy, telex, ordinary
mail or electronic mail), but no such notice or other communication shall be
deemed to have been duly given unless and until it actually is received by the

notices and other communications hereunder are to be delivered by giving the
other parties notice in the manner herein set forth.

       9.3    ENTIRE AGREEMENT.   This Agreement (including the Schedules and
Exhibits hereto and the documents and instruments referred to herein that are to
be delivered at the Closing) constitutes the entire agreement among the parties
hereto and supersedes any prior understandings, agreements or representations by
or among the parties hereto, or any of them, written or oral, with respect to
the subject matter hereof; provided that the Confidentiality Agreement shall
remain in effect in accordance with its terms.

       9.4    NO THIRD PARTY BENEFICIARIES .  Except as provided in
Section 6.13, this Agreement is not intended, and shall not be deemed, to confer
any rights or remedies upon any person other than the parties hereto and their
respective successors and permitted assigns, to create any agreement of
employment with any person or to otherwise create any third-party beneficiary
hereto.

       9.5    ASSIGNMENT .  Neither this Agreement nor any of the rights,
interests or obligations under this Agreement may be assigned or delegated, in
whole or in part, by operation of law or otherwise by any of the parties hereto
without the prior written consent of the other parties, and any such assignment
without such prior written consent shall be null and void, except that the Buyer
and/or the Transitory Subsidiary may assign this Agreement to any direct or

provided that the Buyer and/or the Transitory Subsidiary, as the case may be,
shall remain liable for all of its obligations under this Agreement.  Subject to
the preceding sentence, this Agreement shall be binding upon, inure to the
benefit of, and be enforceable by, the parties hereto and their respective
successors and permitted assigns.

       9.6    SEVERABILITY .  Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.  If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree hereto that the court making such determination
shall have the power to limit the term or provision, to delete specific words or
phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Agreement shall be enforceable as so modified.  In the event such court
does not exercise the power granted to it in the prior sentence, the parties
hereto agree to replace such invalid or unenforceable term or provision with a
valid and enforceable term or provision that will achieve, to the extent
possible, the economic, business and other purposes of such invalid or
unenforceable term.

       9.7    COUNTERPARTS AND SIGNATURE .  This Agreement may be executed in
two or more counterparts, each

<PAGE>

of which shall be deemed an original but all of which together shall be
considered one and the same agreement and shall become effective when

the other parties, it being understood that all parties need not sign the
same counterpart.  This Agreement may be executed and delivered by facsimile
transmission.

       9.8    INTERPRETATION .  When reference is made in this Agreement to an
Article or a Section, such reference shall be to an Article or Section of this
Agreement, unless otherwise indicated.  The table of contents, table of defined
terms and headings contained in this Agreement are for convenience of reference
only and shall not affect in any way the meaning or interpretation of this

corresponding masculine, feminine or neuter forms, and the singular form of
nouns and pronouns shall include the plural, and vice versa.  Any reference to

in accordance with the internal laws of the State of Delaware without giving
effect to any choice or conflict of law provision or rule (whether of the State
of Delaware or any other jurisdiction) that would cause the application of laws
of any jurisdictions other than those of the State of Delaware.

       9.10   REMEDIES .  Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.  The parties hereto agree that irreparable damage

                               STOCKHOLDER AGREEMENT


     STOCKHOLDER AGREEMENT, dated as of September __, 1999 (this "Agreement"),
by the stockholders listed on the signature page(s) hereto (collectively,
"Stockholders" and each individually, a "Stockholder") to and for the benefit of
CMGI, Inc., a Delaware corporation ("Acquiror").  Capitalized terms used and not
otherwise defined herein shall have the respective meanings assigned to them in
the Merger Agreement referred to below.

     WHEREAS, as of the date hereof, the Stockholders collectively own of record
and beneficially shares of capital stock of AdForce, Inc., a Delaware
corporation (the "Company"), as set forth on Schedule I hereto (such shares or
any other voting or equity securities of the Company, hereafter acquired by any
Stockholder prior to the termination of this Agreement, being referred to herein
collectively as the "Shares");

     WHEREAS, concurrently with the execution of this Agreement, Acquiror and
the Company are entering into an Agreement and Plan of Merger, dated as of the
date hereof (the "Merger Agreement"), pursuant to which, upon the terms and
subject to the conditions thereof, a subsidiary of Buyer will be merged with and
into the Company, and the Company will be the surviving corporation (the
"Merger"); and

     WHEREAS, as a condition to the willingness of the Company and Acquiror to
enter into the Merger Agreement, Acquiror has requested that the Stockholders
agree, and in order to induce Acquiror to enter into the Merger Agreement, the
Stockholders are willing to agree to vote in favor of adopting the Merger
Agreement and approving the Merger, upon the terms and subject to the conditions
set forth herein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereby agree, severally and not jointly, as follows:

     Section 1.     VOTING OF SHARES.  Each Stockholder covenants and agrees
that until the termination of this Agreement in accordance with the terms
hereof, at the Company Meeting or any other meeting of the stockholders of the
Company, however called, and in any action by written consent of the
stockholders of the Company, such Stockholder will vote, or cause to be voted,
all of his, her or its respective Shares (a) in favor of adoption of the Merger
Agreement and approval of the Merger contemplated by the Merger Agreement, as
the Merger Agreement may be modified or amended from time to time in a manner
not adverse to the Stockholders, and (b) against any other Alternative
Transaction.  In addition, such Stockholder agrees that it will, upon request by
Acquiror, furnish written confirmation, in form and substance reasonably
acceptable to Acquiror, of such Stockholder's vote in favor of the Merger
Agreement and the Merger. Each Stockholder covenants and agrees to deliver to
Acquiror upon request prior to any vote contemplated by the first sentence of
this Section 1, a proxy substantially in the form attached hereto as ANNEX A (a
"Proxy"), which Proxy shall be irrevocable during the term of this Agreement to
the extent permitted under Delaware law, and Acquiror agrees to vote the Shares
subject to such Proxy in favor of the approval and adoption of the Merger
Agreement and the Merger. Each Stockholder acknowledges receipt and review of a
copy of the Merger Agreement. Each Stockholder acknowledges and agrees that the
Proxy, if and when given, shall be coupled with an interest, shall constitute,
among other things, an inducement for Acquiror to enter into the Merger
Agreement, shall be irrevocable and shall not be terminated by operation of law
or otherwise upon the occurrence of any event and that no subsequent proxies
with respect to such Shares shall be given (and if given shall not be
effective); provided however that any such proxy shall terminate automatically
and without further action on behalf of the Stockholders upon the termination of
this Agreement.  In the event that a Stockholder does not provide the Proxy upon
request of Acquiror, such Stockholder hereby grants Buyer a power of attorney to
execute and deliver such Proxy for and on behalf of such Stockholder, which

<PAGE>

power of attorney is coupled with an interest and shall survive any death,
disability, bankruptcy or any other such impediment of such Stockholder.  Upon
the execution of this Agreement by each Stockholder, such Stockholder hereby
revokes any and all prior proxies or powers of attorney given by such
Stockholder with respect to the Shares.

     Section 2.     TRANSFER OF SHARES.  Each Stockholder covenants and agrees
that such Stockholder will not directly or indirectly, (a) sell, assign,
transfer (including by merger, testamentary disposition, interspousal
disposition pursuant to a domestic relations proceeding or otherwise by
operation of law), pledge, encumber or otherwise dispose of any of the Shares,
(b) deposit any of the Shares into a voting trust or enter into a voting
agreement or arrangement with respect to the Shares or grant any proxy or power
of attorney with respect thereto which is inconsistent with this Agreement or
(c) enter into any contract, option or other arrangement or undertaking with
respect to the direct or indirect sale, assignment, transfer (including by
merger, testamentary disposition, interspousal disposition pursuant to a
domestic relations proceeding or otherwise by operation of law) or other
disposition of any Shares (each such case, a "Transfer"), unless the transferee
to which any such Shares are or may be Transferred shall have executed a
counterpart of this Agreement and agreed in writing to hold such Shares subject
to all the terms and conditions of this Agreement.

     Section 3.     REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS.  Each
Stockholder on its own behalf hereby severally represents and warrants to
Acquiror with respect to itself and its or her ownership of the Shares as
follows:

     (a)  OWNERSHIP OF SHARES.  On the date hereof, the Shares held by such
Stockholder are owned beneficially by such Stockholder or its nominee.  Such
Stockholder has sole voting power, without restrictions, with respect to all of
such Shares.

     (b)  POWER, BINDING AGREEMENT.  Such Stockholder has the legal capacity,
power and authority to enter into and perform all of its obligations, under this
Agreement. The execution, delivery and performance of this Agreement by such
Stockholder will not violate any material agreement to which such Stockholder is
a party, including, without limitation, any voting agreement, stockholders'
agreement, partnership agreement or voting trust. This Agreement has been duly
and validly executed and delivered by such Stockholder and constitutes a valid
and binding obligation of such Stockholder, enforceable against such Stockholder
in accordance with its terms, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally and subject, as to enforceability, to
general principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity).

     (c)  NO CONFLICTS.  The execution and delivery of this Agreement do not,
and the consummation of the transactions contemplated hereby by such Stockholder
will not, conflict with or result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to loss of a
material benefit under, any provision of any loan or credit agreement, note,
bond, mortgage, indenture, lease, or other agreement, instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to such Stockholder or any of its
properties or assets, other than such conflicts, violations or defaults or
terminations, cancellations or accelerations which individually or in the
aggregate do not materially impair the ability of such Stockholder to perform
its obligations hereunder.

     Section 4.     NO SOLICITATION.  Subject to the provisions of Section 7
below, prior to the termination of this Agreement in accordance with its terms,
each Stockholder agrees, in its individual capacity as a stockholder of the
Company that (i) it will not, nor will it authorize or permit any of its
employees, agents and representatives to, directly or indirectly, (a) initiate,
solicit or encourage any inquiries or the making of any Acquisition Proposal (as
defined in the Merger Agreement), (b) enter into any agreement with respect to
any Acquisition Proposal, or (c) participate in any discussions or

<PAGE>

negotiations regarding, or furnish to any person any information with respect
to, or take any other action to facilitate any inquiries or the making of any
proposal that constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal, and (ii) it will notify Acquiror as soon as possible if
any such inquiries or proposals are received by, any information or documents
is requested from, or any negotiations or discussions are sought to be
initiated or continued with, it or any of its affiliates in its individual
capacity.

     Section 5.     TERMINATION.  This Agreement shall terminate upon the
earliest to occur of (i) the Effective Time (as such term is defined in the
Merger Agreement) or (ii) any termination of the Merger Agreement in accordance
with the terms thereof; PROVIDED that no such termination shall relieve any
party of liability for a willful breach hereof prior to termination.

     Section 6.     SPECIFIC PERFORMANCE. The parties hereto agree that
irreparable damage would occur in the event any provision of this Agreement was
not performed in accordance with the terms hereof and that the parties shall be
entitled to specific performance of the terms hereof, in addition to any other
remedy at law or in equity.

     Section 7.     FIDUCIARY DUTIES.  Each Stockholder is signing this
Agreement solely in such Stockholder's capacity as an owner of his, her or its
respective Shares, and nothing herein shall prohibit, prevent or preclude such
Stockholder from taking or not taking any action in his or her capacity as an
officer or director of the Company, to the extent permitted by the Merger
Agreement.

     Section 8.     MISCELLANEOUS.

     (a)  This Agreement constitutes the entire agreement between the parties
hereto with respect to the subject matter hereof and supersedes all prior
agreements and understandings, both written and oral, between the parties with
respect thereto. This Agreement may not be amended, modified or rescinded except
by an instrument in writing signed by each of the parties hereto.

     (b)  If any term or other provision of this Agreement is invalid, illegal
or incapable of being enforced by any rule of law, or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect. Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible to the fullest extent permitted by
applicable law in a mutually acceptable manner in order that the terms of this
Agreement remain as originally contemplated to the fullest extent possible.

     (c)  This Agreement shall be governed by and construed in accordance with
the laws of the State of Delaware without regard to the principles of conflicts
of law thereof.

     (d)  This Agreement may be executed in counterparts, each of which shall be
deemed an original and all of which together shall constitute one and the same
instrument.

     IN WITNESS WHEREOF, each of the parties hereto has caused this Agreement w
be signed individually or by its respective duly authorized officer as of the

dated as of September 20, 1999 (the "Agreement"), between CMGI, Inc., a Delaware
corporation ("Acquiror"), a subsidiary of Acquiror ("Sub") and the Company, Sub
will be merged with and into the Company (the "Merger") and the Company will be
the surviving corporation.

     As a result of the Merger, I may receive shares of common stock, par value
$.01 per share, of Acquiror (the "Acquiror Common Stock") in exchange for shares
owned by me of common stock of the Company ("Company Common Stock").

     1.   COMPLIANCE WITH THE ACT.  I represent, warrant and covenant to
Acquiror that in the event I receive any Acquiror Common Stock as a result of
the Merger:

          (a)  I shall not make any sale, transfer or other disposition of the
Acquiror Common Stock in violation of the Act or the Rules and Regulations.

          (b)  I have carefully read this letter and the Agreement and discussed
the requirements of such documents and other applicable limitations upon my
ability to sell, transfer or otherwise dispose of the Acquiror Common Stock to
the extent I felt necessary, with my counsel or counsel for the Company.

          (c)  I have been advised that the issuance of Acquiror Common Stock to
me pursuant to the Merger will be registered with the Commission under the Act
on a Registration Statement on Form S-4.  However, I have also been advised
that, since at the time the Merger is submitted for a vote of the stockholders
of the Company, I may be deemed to have been an affiliate of the Company and the
distribution by me of the Acquiror Common Stock has not been registered under
the Act, I may not sell, transfer or otherwise dispose of the Acquiror Common
Stock issued to me in the Merger unless (i) such sale, transfer or other
disposition as been registered under the Act, (ii) such sale, transfer or
disposition is made in conformity with Rule 145 promulgated by the Commission
under the Act, or (iii) in the opinion of counsel reasonably undersigned
acquired the Acquiror Common Stock received in the Merger and the provisions of
Rule 145(d)(2) are then available to the undersigned,. (ii) two years shall have
elapsed from the date the undersigned acquired Acquiror Common Stock received in
the Merger and the provisions of Rule 145(d)(3) are then available to the
undersigned, or (iii) Acquiror has received either a broker's letter with
respect to the sale of the shares represented by such certificate(s) stating
that each of the requirements of Rule 145(d)(1) has been met, or a "no action"
letter obtained by the undersigned from the staff of the Commission, to the
effect that the restrictions imposed by Rule 145 under the Act no longer apply
to the undersigned.

     2.   CERTAIN TAX MATTERS.  The undersigned does not intend to take a
position on any federal or state income tax return that is inconsistent with the
treatment of he Merger as a tax-free reorganization for federal or state income
tax purposes.

                              Very truly yours,




                              Signature

                                STOCK OPTION AGREEMENT


     STOCK OPTION AGREEMENT, dated as of September 20, 1999 (the
"Agreement"), between CMGI, Inc., a Delaware corporation (the "Grantee"), and
AdForce, Inc., a Delaware corporation (the "Grantor").

     WHEREAS, the Grantee, the Grantor and Artichoke Corp., a wholly owned
subsidiary of the Grantee ("Newco"), are entering into an Agreement and Plan
of Merger, dated as of the date hereof (the "Merger Agreement"), which
provides, among other things, for the merger (the "Merger") of Newco with and
into the Grantor;

     WHEREAS, as a condition to its willingness to enter into the Merger
Agreement, the Grantee has requested that the Grantor grant to the Grantee an
option to purchase the shares of Common Stock of the Grantor (the "Common
Stock") covered hereby, upon the terms and subject to the conditions hereof;
and

     WHEREAS, in order to induce the Grantee to enter into the Merger
Agreement, the Grantor is willing to grant the Grantee the requested option.

     NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth herein, the parties hereto agree as
follows:

     1.   THE OPTION; EXERCISE; ADJUSTMENTS; TERMINATION.

          (a)  Contemporaneously herewith the Grantee, Newco and the Grantor
are entering into the Merger Agreement.  Subject to the other terms and
conditions set forth herein, the Grantor hereby grants to the Grantee an
irrevocable option (the "Option") to purchase up to 3,978,761 shares of
Common Stock (the "Shares") at a cash purchase price equal to $20.96 per
Share (the "Purchase Price"); PROVIDED, HOWEVER, that the number of shares
issuable to Buyer pursuant hereto shall not exceed 19.9% of the outstanding
shares of Common Stock.  The Option may be exercised by the Grantee, in whole
or in part, at any time, or from time to time, after the earlier of (i)
termination of the Merger Agreement by Buyer under Section 8.1(e) or Section
8.1(f) of the Merger Agreement, or (ii) immediately prior to the occurrence
of any event causing the termination fee to become payable to Buyer pursuant
to Section 8.3(c)(iii) of the Merger Agreement, PROVIDED that, in the case of
this clause (ii), an Alternative Transaction involving the Company has been
proposed or consummated prior to the Company Meeting.

          (b)  In the event of any change in the number of issued and
outstanding shares of Common Stock by reason of any stock dividend, stock
split, reverse stock split, split-up, recapitalization, merger or other
change in the corporate or capital structure of the Grantor, the number of
Shares subject to the Option and the purchase price per Share shall be
appropriately adjusted.

          (c)  In the event the Grantee wishes to exercise the Option, the
Grantee shall send a written notice to the Grantor (the "Exercise Notice")
specifying a date (subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act")) not later
than 10 business days and not earlier than the third business day following
the date such notice is given for the closing of such purchase.

          (d)  The right to exercise the Option shall terminate at the
earliest of (i) the Effective Time (as defined in the Merger Agreement), (ii)
the termination of the Merger Agreement pursuant to circumstances under which
the Grantee is not entitled to receive the termination fee pursuant to
Section 8.3 of the Merger Agreement, (iii) the date on which Grantee realizes
a Total Profit equal to the Profit Limit (as such terms are defined in
Section

<PAGE>

8) and (iv) 90 days after the date (the "Merger Termination Date") on
which the Merger Agreement is terminated (the date referred to in clause (iv)
being hereinafter referred to as the "Option Expiration Date"); PROVIDED
THAT if the Option cannot be exercised or the Shares cannot be delivered to
Grantee upon such exercise because the conditions set forth in Section 2(a)
or Section 2(b) hereof have not yet been satisfied, the Option Expiration
Date shall be extended until 15 days after such impediment to exercise has
been removed so long as Grantee is using reasonable best efforts to remove
the impediment.

     2.   CONDITIONS TO DELIVERY OF SHARES.  The Grantor's obligation to
deliver Shares upon exercise of the Option is subject only to the conditions
that:

          (a)  No preliminary or permanent injunction or other order issued
by any federal or state court of competent jurisdiction in the United States
prohibiting the delivery of the Shares shall be in effect; and

          (b)  Any applicable waiting periods under the HSR Act shall have
expired or been terminated.

     3.   THE CLOSING.

          (a)  Any closing hereunder shall take place on the date specified
by the Grantee in its Exercise Notice at 9:00 A.M., local time, at the
offices of Hale and Dorr LLP, 60 State Street, Boston, Massachusetts, or, if
the conditions set forth in Section 2(a) or 2(b) have not then been
satisfied, on the second business day following the satisfaction of such
conditions, or at such other time and place as the parties hereto may agree
(the "Closing Date").  On the Closing Date, the Grantor will deliver to the
Grantee a certificate or certificates, duly endorsed (or accompanied by duly
executed stock powers), representing the Shares in the denominations
designated by the Grantee in its Exercise Notice and the Grantee will
purchase such Shares from the Grantor at the price per Share equal to the
Purchase Price.  Any payment made by the Grantee to the Grantor, or by the
Grantor to the Grantee, pursuant to this Agreement shall be made by certified
or official bank check or by wire transfer of federal funds to a bank
designated by the party receiving such funds.

          (b)  The certificates representing the Shares may bear an
appropriate legend relating to the fact that such Shares have not been
registered under the Securities Act of 1933, as amended (the "Securities
Act").

     4.   REPRESENTATIONS AND WARRANTIES OF THE GRANTOR.  The Grantor
represents and warrants to the Grantee that:  (a) the Grantor is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware and has the requisite corporate power and
authority to enter into and perform this Agreement; (b) the execution and
delivery of this Agreement by the Grantor and the consummation by it of the
transactions contemplated hereby have been duly authorized by the Board of
Directors of the Grantor and this Agreement has been duly executed and
delivered by a duly authorized officer of the Grantor and constitutes a valid
and binding obligation of the Grantor, enforceable in accordance with its
terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating
to or affecting creditors' rights and to general equity principles; (c) the
Grantor has taken all necessary corporate action to authorize and reserve the
Shares issuable upon exercise of the Option and the Shares, when issued and
delivered by the Grantor upon exercise of the Option, will be duly
authorized, validly issued, fully paid and non-assessable and free of any
lien, security interest or other adverse claim and free of any preemptive
rights; (d) except as otherwise required by the HSR Act, the execution and
delivery of this Agreement by the Grantor and the consummation by it of the
transactions contemplated hereby do not require the consent, waiver, approval
or authorization of or any filing with any person or public authority and
will not violate, require a consent or waiver under, result in a breach of or
the acceleration of any obligation under, or constitute a default under, any
provision of any charter or by-law, indenture, mortgage, lien, lease,
agreement, contract, instrument, order, law, rule, regulation, stock market
rule, judgment, ordinance, decree or restriction by which the Grantor or any
of its subsidiaries or any of their respective

<PAGE>

properties or assets is bound; and (e) no "fair price", "moratorium",
"control share acquisition" or other form of anti-takeover statute or
regulation is or shall be applicable to the acquisition of Shares pursuant to
this Agreement.

     5.   REPRESENTATIONS AND WARRANTIES OF THE GRANTEE.  The Grantee
represents and warrants to the Grantor that:  (a) the execution and delivery
of this Agreement by the Grantee and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Grantee and this Agreement has been duly
executed and delivered by a duly authorized officer of the Grantee and will
constitute a valid and binding obligation of Grantee; and (b) the Grantee is
acquiring the Option and, if and when it exercises the Option, will be
acquiring the Shares issuable upon the exercise thereof for its own account
and not with a view to distribution or resale in any manner which would be in
violation of the Securities Act; and (c) the Grantor is an "accredited
investor" as such term is defined in the Securities Act.

     6.   LISTING OF SHARES; HSR ACT FILINGS; GOVERNMENTAL CONSENTS.  Subject
to applicable law and the rules and regulations of the Nasdaq National
Market, the Grantor shall (i) promptly file a notice to list the Shares on
the Nasdaq National Market and (ii) make, as promptly as practicable, all
necessary filings by the Grantor under the HSR Act and use its reasonable
best efforts to obtain all necessary approvals thereunder as promptly as
practicable; provided, however, that if the Grantor is unable to effect such
listing on the Nasdaq National Market by the Closing Date, the Grantor will
nevertheless be obligated to deliver the Shares upon the Closing Date.  Each
of the parties hereto will use its reasonable best efforts to obtain consents
of all third parties and governmental authorities, if any, necessary to the
consummation of the transactions contemplated.

     7.   REGISTRATION RIGHTS.

          (a)  In the event that the Grantee shall desire to sell any of the
Shares within two years after the purchase of such Shares pursuant hereto,
and such sale requires, in the opinion of counsel to the Grantee, which
opinion shall be reasonably satisfactory to the Grantor and its counsel,
registration of such Shares under the Securities Act, the Grantor will
cooperate with the Grantee and any underwriters in registering such Shares
for resale, including, without limitation, promptly filing a registration
statement which complies with the requirements of applicable federal and
state securities laws and entering into an underwriting agreement with such
underwriters upon such terms and conditions as are customarily contained in
underwriting agreements with respect to secondary distributions; provided
that the Grantor shall not be required to have declared effective more than
two registration statements hereunder and shall be entitled to delay the
filing or effectiveness of any registration statement for up to 120 days if
the offering would, in the judgment of the Board of Directors of the Grantor,
require premature disclosure of any material corporate development or
otherwise interfere with or adversely affect any pending or proposed offering
of securities of the Grantor or any other material transaction involving the
Grantor.

          (b)  If the Common Stock is registered pursuant to the provisions
of this Section 7, the Grantor agrees (i) to furnish copies of the
registration statement and the prospectus relating to the Shares covered
thereby in such numbers as the Grantee may from time to time reasonably
request and (ii) if any event shall occur as a result of which it becomes
necessary to amend or supplement any registration statement or prospectus, to
prepare and file under the applicable securities laws such amendments and
supplements as may be necessary to keep available for at least 90 days a
prospectus covering the Common Stock meeting the requirements of such
securities laws, and to furnish to the Grantee such numbers of copies of the
registration statement and prospectus as amended or supplemented as may
reasonably be requested.  The Grantor shall bear the cost of the
registration, including, but not limited to, all registration and filing
fees, printing expenses, and fees and disbursements of counsel and
accountants for the Grantor, except that the Grantee shall pay the fees and
disbursements of its counsel and the underwriting fees and selling
commissions applicable to the Shares sold by the Grantee.  The Grantor shall
indemnify and hold harmless Grantee, its affiliates and its officers and
directors from and against any and all losses,

<PAGE>

claims, damages, liabilities and expenses arising out of or based upon any
statements contained in, omissions or alleged omissions from, each
registration statement filed pursuant to this paragraph; PROVIDED, HOWEVER,
that this provision does not apply to any loss, liability, claim, damage or
expense to the extent it arises out of any statement or omission made in
reliance upon and in conformity with written information furnished to the
Grantor by the Grantee, its affiliates or its officers expressly for use in
any registration statement (or any amendment thereto) or any preliminary
prospectus filed pursuant to this paragraph.  The Grantor shall also
indemnify and hold harmless each underwriter and each person who controls any
underwriter within the meaning of either the Securities Act or the Securities
Exchange Act of 1934 against any and all losses, claims, damages, liabilities
and expenses arising out of or based upon any statements contained in,
omissions or alleged omissions from, each registration statement filed
pursuant to this paragraph; PROVIDED, HOWEVER, that this provision does not
apply to any loss, liability, claim, damage or expense to the extent it
arises out of any statement or omission made in reliance upon and in
conformity with written information furnished to the Grantor by the
underwriters expressly for use in any registration statement (or any
amendment thereto) or any preliminary prospectus filed pursuant to this
paragraph.  The Grantee shall indemnify and hold harmless Grantor, its
affiliates and its officers and directors, and each underwriter and each
person who controls any underwriter within the meaning of either the
Securities Act or the Securities Act of 1934, from and against any and all
losses, claims, damages, liabilities and expenses arising out of or based
upon any statement contained in, omissions or alleged omissions from, each
registration statement filed pursuant to this paragraph to the extent that
such statement or omission is made in reliance upon and in conformity with
written information furnished to the Grantor by the Grantee, its affiliates
or its officers expressly for use in such registration statement.

     8.   PROFIT LIMITATION.

          (a)  Notwithstanding any other provision of this Agreement, in no
event shall the Grantee's Total Profit (as hereinafter defined) exceed $30
million (the "Profit Limit") and, if it otherwise would exceed such amount,
the Grantee, at its sole election, shall either (i) deliver to the Grantor
for cancellation Shares previously purchased by Grantee, (ii) pay cash to the
Grantor, (iii) receive a smaller termination fee under Section 8.3 of the
Merger Agreement, (iv) limit the number of Shares purchased hereunder, or (v)
undertake any combination thereof, so that Grantee's Total Profit shall not
exceed the Profit Limit after taking into account the foregoing actions.

          (b)  Notwithstanding any other provision of this Agreement, the
Option may not be exercised for a number of Shares as would, as of the date
of the Exercise Notice, result in a Notional Total Profit (as defined below)
of more than the Profit Limit and, if exercise of the Option otherwise would
exceed the Profit Limit, the Grantee, at its discretion, may increase the
Purchase Price for that number of Shares set forth in the Exercise Notice so
that the Notional Total Profit shall not exceed the Profit Limit; PROVIDED,
that nothing in this sentence shall restrict any exercise of the Option
permitted hereby on any subsequent date at the Purchase Price set forth in
Section 1(a) hereof.

          (c)  As used herein, the term "Total Profit" shall mean the
aggregate amount (before taxes) of the following:  (i) the amount of cash
received by Grantee pursuant to Section 8.3(c) of the Merger Agreement, and
(ii) (x) the cash amounts (net of customary brokerage commissions paid in
connection with the transaction) received by Grantee pursuant to the sale of
Shares (or any other securities into which such Shares are converted or
exchanged) to any unaffiliated party, less (y) the Grantee's purchase price
for such Shares.

          (d)  As used herein, the term "Notional Total Profit" with respect
to any number of Shares as to which Grantee may propose to exercise the
Option shall be the Total Profit determined as of the date of the Exercise
Notice assuming that the Option were exercised on such date for such number
of Shares and assuming that such Shares, together with all other Shares held
by Grantee and its affiliates as of such date, were sold for cash at the
closing market price for the Common Stock as of the close of business on the
preceding trading day (less customary brokerage commissions).

<PAGE>

     9.   EXPENSES.  Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise specifically provided
herein.

     10.  SPECIFIC PERFORMANCE.  The Grantor acknowledges that if the Grantor
fails to perform any of its obligations under this Agreement, immediate and
irreparable harm or injury would be caused to the Grantee for which money
damages would not be an adequate remedy.  In such event, the Grantor agrees
that the Grantee shall have the right, in addition to any other rights it may
have, to specific performance of this Agreement.  Accordingly, if the Grantee
should institute an action or proceeding seeking specific enforcement of the
provisions hereof, the Grantor hereby waives the claim or defense that the
Grantee has an adequate remedy at law and hereby agrees not to assert in any
such action or proceeding the claim or defense that such a remedy at law
exists.  The Grantor further agrees to waive any requirements for the
securing or posting of any bond in connection with obtaining any such
equitable relief.

     11.  NOTICE.  All notices, requests, demands and other communications
hereunder shall be deemed to have been duly given and made if in writing and
if served by personal delivery upon the party for whom it is intended or
delivered by registered or certified mail, return receipt requested, or if

                               STOCKHOLDER AGREEMENT


     STOCKHOLDER AGREEMENT, dated as of September __, 1999 (this
"Agreement"), by the stockholders listed on the signature page(s) hereto
(collectively, "Stockholders" and each individually, a "Stockholder") to and
for the benefit of CMGI, Inc., a Delaware corporation ("Acquiror").
Capitalized terms used and not otherwise defined herein shall have the
respective meanings assigned to them in the Merger Agreement referred to
below.

     WHEREAS, as of the date hereof, the Stockholders collectively own of
record and beneficially shares of capital stock of AdForce, Inc., a Delaware
corporation (the "Company"), as set forth on Schedule I hereto (such shares
or any other voting or equity securities of the Company, hereafter acquired
by any Stockholder prior to the termination of this Agreement, being referred
to herein collectively as the "Shares");

     WHEREAS, concurrently with the execution of this Agreement, Acquiror and
the Company are entering into an Agreement and Plan of Merger, dated as of
the date hereof (the "Merger Agreement"), pursuant to which, upon the terms
and subject to the conditions thereof, a subsidiary of Buyer will be merged
with and into the Company, and the Company will be the surviving corporation
(the "Merger"); and

     WHEREAS, as a condition to the willingness of the Company and Acquiror
to enter into the Merger Agreement, Acquiror has requested that the
Stockholders agree, and in order to induce Acquiror to enter into the Merger
Agreement, the Stockholders are willing to agree to vote in favor of adopting
the Merger Agreement and approving the Merger, upon the terms and subject to
the conditions set forth herein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and intending to be legally bound
hereby, the parties hereby agree, severally and not jointly, as follows:

     Section 1.     VOTING OF SHARES.  Each Stockholder covenants and agrees
that until the termination of this Agreement in accordance with the terms
hereof, at the Company Meeting or any other meeting of the stockholders of
the Company, however called, and in any action by written consent of the
stockholders of the Company, such Stockholder will vote, or cause to be
voted, all of his, her or its respective Shares (a) in favor of adoption of
the Merger Agreement and approval of the Merger contemplated by the Merger
Agreement, as the Merger Agreement may be modified or amended from time to
time in a manner not adverse to the Stockholders, and (b) against any other
Alternative Transaction.  In addition, such Stockholder agrees that it will,
upon request by Acquiror, furnish written confirmation, in form and substance
reasonably acceptable to Acquiror, of such Stockholder's vote in favor of the
Merger Agreement and the Merger. Each Stockholder covenants and agrees to
deliver to Acquiror upon request prior to any vote contemplated by the first
sentence of this Section 1, a proxy substantially in the form attached hereto
as ANNEX A (a "Proxy"), which Proxy shall be irrevocable during the term of

                  CMGI STRENGTHENS INTERNET MARKETING ARSENAL WITH
                               ACQUISITION OF ADFORCE

         Acquisition Solidifies Interactive Ad Serving, Measurement, Sales
                       and Targeting Infrastructure for CMGI

Andover, Mass. and Cupertino, CA, September 20, 1999 - CMGI, Inc. (Nasdaq:
CMGI) announced today that it has signed a definitive agreement to acquire
AdForce, Inc. (Nasdaq: ADFC) in a stock-for-stock tax-free merger valued at
approximately $500 million. Under the terms of the agreement, CMGI will issue
0.262 CMGI shares for every share of AdForce held on the closing date of the
transaction. Closing of the merger is subject to customary conditions,
including formal approval by AdForce shareholders, expected later this year.

The merger builds on both companies' strengths to create a broad
infrastructure for the overall delivery of ad serving and digital media
services, and is yet another addition to CMGI's strong stable of core
advertising infrastructure technologies. Following completion of the
acquisition, AdForce will become the latest member of CMGI's group of
majority-owned operating companies.

According to David Andonian, President of Corporate Development for CMGI,
"AdForce has significantly increased their reach and momentum over the last
year to become a leader in the delivery and measurement of online advertising
campaigns. As a part of the CMGI network, AdForce will continue to expand its
customer base by providing services to many of the CMGI-affiliated companies,
well beyond their current Adsmart and Engage relationships. The integration
of AdForce's highly scalable ad serving and measurement tools is another
important step in helping CMGI reach its goals of building a
fully-integrated, interactive marketing machine."

Chuck Berger, AdForce Chairman and CEO added, "The rapid growth in the demand
of online advertising services will continue to accelerate, reaching a
projected market size of more than $32 billion by the year 2004, according to
Forrester Research. To creation, delivery and analysis of their marketing
campaigns. The combination of AdForce's state of the art ad delivery and
CMGI's leading content and infrastructure companies will create a new kind of
digital marketing company, capable of providing the full range of services
required by the global Internet economy".

This agreement furthers the relationship established between AdForce and CMGI
earlier this year as a result of AdForce's strategic partnerships with Engage
and Adsmart, two of the CMGI operating companies. As previously announced,
AdForce is currently the primary ad-serving company for the Adsmart Network
(http://www.adsmart.net), now including more than 300 Web sites totaling 2
billion monthly impressions. In addition, Engage and AdForce announced a
collaborative solution that combines AdForce's centralized online ad
management system with Engage's Precision Profiling technology and consumer
interest data from Engage Knowledge, a Web wide database containing more than
30 million anonymous consumer interest profiles. Engage enablement of the
AdForce ad management system is on target for completion in Q4 1999.

As a formal member of the CMGI network, AdForce can strengthen these
relationships while making its technology more broadly available to the
nearly 50 CMGI affiliated companies.
