          targeting technologies supported by our large and growing database of

        Growth of the Internet generally and electronic commerce in particular
has spurred traditional businesses to devote larger portions of their marketing
budgets to Internet advertising, and has prompted Internet and electronic
commerce companies to increase their spending on Internet advertising. Jupiter
Communications estimates that spending on Internet advertising will grow from
$1.9 billion in 1998 to $7.7 billion in 2002, and the Direct Marketing
Association estimates that spending on Internet direct marketing will grow from
$603 million in 1998 to $5.3 billion in 2003.
 
        During 1998, we delivered 13.6 billion ads with increasing quarterly ad
volumes of 0.9 billion, 1.6 billion, 3.2 billion and 7.9 billion. We delivered
13.2 billion ads in the first quarter of 1999. Our key customers include 24/7
Media, Adsmart, GeoCities, Netscape and ModemMedia.PoppeTyson.
 
        We incorporated in California as Imgis, Inc. on January 16, 1996 and
reincorporated in Delaware as AdForce, Inc. in April 1999. Our address is 10590
North Tantau Avenue, Cupertino, California 95014, and our telephone number is

                                  RISK FACTORS
 
        YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND ALL OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE PURCHASING OUR COMMON STOCK.
INVESTING IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. ANY OF THE
FOLLOWING RISKS COULD MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS AND QUARTERLY
AND ANNUAL RESULTS OF OPERATIONS AND COULD RESULT IN A COMPLETE LOSS OF YOUR
INVESTMENT.
 
OUR LIMITED OPERATING HISTORY MAKES IT DIFFICULT TO PREDICT FUTURE RESULTS OF
  OPERATIONS AND TO ADDRESS RISKS AND UNCERTAINTIES
 
        We incorporated in January 1996 and have a limited operating history.
You should consider the risks and difficulties frequently encountered by early
stage companies in new and rapidly evolving markets, particularly those
companies whose businesses depend on the Internet. These risks and difficulties
include our inability to predict future results of operations accurately due to
our lack of operating history and the unavailability of comparable business
models. We cannot assure you that our business strategy will be successful or
that we will address these risks and difficulties successfully.
 
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE, WHICH COULD AFFECT THE MARKET
  PRICE OF YOUR SHARES
 
        Our quarterly results of operations have varied in the past. You should
not rely on quarter-to-quarter comparisons of our results of operations as an
indication of our future performance. It is likely that in future periods our
results of operations will be below the expectations of securities analysts and
investors. If so, the market price of your shares would likely decline. Our
revenue and quarterly results of operations depend on a variety of factors, many
of which are beyond our control. Please see "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Fluctuations in
Results of Operations" for a list of these factors.
 
        We expect to make significant capital expenditures as we increase the
capacity and reliability of our existing technology infrastructure and data
center. We also intend to open additional ad management and delivery centers. We
intend to increase our sales and marketing operations and to continue to
allocate a large portion of our budget for research and development. Our
operating costs are relatively fixed. We would likely be unable to adjust
spending quickly enough to offset any unexpected revenue shortfall. If we have a
shortfall in revenue relative to our expenses, our quarterly and annual results
of operations would be materially and adversely affected, which in turn could
affect the market price of your shares.
 
WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES
 
   
        We expect to continue to incur net losses on a quarterly and annual
basis for at least the next two years. If our revenue does not grow or grows
more slowly than we anticipate, or if our operating or capital expenditures
exceed our expectations and cannot be reduced, our quarterly and annual results
of operations will be materially and adversely affected. We incurred net losses
of $3.5 million for the period from January 16, 1996 (inception) to December 31,
1996, $5.7 million for the year ended December 31, 1997, $15.6 million for year
ended December 31, 1998, and $5.0 million for the three months ended March 31,
1999. We expect to continue to incur significant operating expenditures, and
capital expenditures of at least $9.0 million, for the remainder of 1999. As a
result, we will need to generate significantly greater revenue than we have
generated to date to achieve and maintain profitability. We expect that future
revenue growth, if any, will not be as rapid as in recent periods. We may never
achieve profitability on a quarterly or an annual basis.
    
 
WE DEPEND ON A SMALL NUMBER OF CUSTOMERS FOR OUR REVENUE, THE LOSS OF ANY OF
  WHICH WOULD ADVERSELY AFFECT OUR ABILITY TO GENERATE REVENUE
 
        We derive a substantial portion of our net revenue from a small number
of Web sites and ad rep firms. Our quarterly and annual results of operations
would be materially and adversely affected by the
 
                                       6
<PAGE>
loss of any of these customers or any significant reduction in net revenue
generated from these customers. Our three largest customers for each quarter of
1998 represented 94%, 81%, 60% and 63% of our net revenue. In the first quarter
of 1999, four of our customers, 24/7 Media, Adsmart, GeoCities and Netscape,
accounted for approximately 77% of our net revenue. Our customer agreements can
generally be terminated at any time with little or no penalty.
 
CONSOLIDATION IN THE INTERNET INDUSTRY MAY ADVERSELY AFFECT OUR ABILITY TO
  RETAIN OUR PRINCIPAL CUSTOMERS, THE LOSS OF ANY OF WHICH WOULD ADVERSELY
  AFFECT OUR ABILITY TO GENERATE REVENUE
 
        Many of our principal customers are now and may in the future be
affected by rapid consolidation in the Internet industry. Our quarterly and
annual results of operations would be materially and adversely affected if we
lose any of these customers as a result of consolidation or if our customers are
required to use the proprietary ad delivery technologies of the companies that
acquire them or other ad delivery technologies. Please see
"Business--Competition" for detailed information on industry consolidation.
 
WE MAY NOT BE ABLE TO SCALE OUR TECHNOLOGY INFRASTRUCTURE, WHICH WOULD ADVERSELY
  AFFECT OUR ABILITY TO RETAIN OUR EXISTING CUSTOMERS AND TO ATTRACT NEW
  CUSTOMERS
 
        Our technology infrastructure may not be able to support higher volumes
of ads, additional customers or new types of advertising or direct marketing. If
we are not able to scale our technology infrastructure, we would have difficulty
retaining existing customers and attracting new customers. If our traffic
increases because of heightened demand from existing or new customers, we will
need to accommodate large increases in the number of ads that we manage and
deliver and the amount of data that we store. We will also need to support the
introduction of new and evolving types of advertising and direct marketing that
require greater system resources than current methods of Internet advertising.
 
        We may not be able to continue to scale our data centers on time or
within budget. The uninterrupted performance of our data centers is critical to
our success. We expect to add more data centers to improve redundancy and to
increase capacity. Adding capacity will be expensive, and we may not be able to
do so successfully. In addition, we cannot assure you that we will be able to
protect our new or existing data centers from unexpected events as we scale our
systems. Please see "Business-- Technology and Data Center Operations" for
detailed information on our system capacity.
 
WE MAY NOT BE ABLE TO RESPOND TO RAPID TECHNOLOGICAL CHANGE, WHICH COULD
  ADVERSELY AFFECT OUR ABILITY TO RETAIN OUR EXISTING CUSTOMERS AND TO ATTRACT
  NEW CUSTOMERS
 
        We may not be able to improve our technology infrastructure to respond
to technological change, changes in customer requirements or preferences, or new
industry standards. We must be able to steadily increase our system capacity,
improve our existing services, and introduce new service offerings without
interrupting or interfering with our operations, and we must be able to do so in
a timely and cost-effective manner. We must ensure that our technology
infrastructure is flexible enough to accommodate technology advancements,
including our ability to deliver ads to a customer base that uses multiple
browsers and multiple versions of those browsers. We must also ensure that our
technology infrastructure is flexible enough to accommodate new customer
requirements and preferences. For example, in August 1998, we had difficulties
transitioning GeoCities from an on-site ad server to our service, AdForce for
Publishers, causing them to revert to their existing on-site ad server for that
month. The difficulties were resolved and GeoCities resumed using our service in
September 1998. Please see "Business--Technology and Data Center Operations" for
detailed information on our technology infrastructure.
 
                                       7
<PAGE>
WE MAY NOT BE ABLE TO ATTRACT AD AGENCIES AND ADVERTISERS AS CUSTOMERS, WHICH
  COULD CAUSE US TO MISS OUR FINANCIAL PROJECTIONS OR THOSE OF SECURITIES
  ANALYSTS
 
        If we fail to attract advertisers and ad agencies as customers or do so
more slowly than we anticipate, we may not meet our financial projections or
those of securities analysts. We currently have no agreements with individual
advertisers, and ad agencies accounted for less than 5% of our net revenue in
the first quarter of 1999. The service and support requirements of advertisers
and ad agencies are significantly different from those of Web sites and ad rep
firms, and advertisers and ad agencies may not accept third-party Internet ad
management and delivery services or may not choose our services over those
offered by others. Moreover, advertisers and ad agencies may find Internet
advertising services to be too complex, ineffective or otherwise unsatisfactory
for managing and delivering their ad campaigns.
 
WE MAY NOT COMPETE SUCCESSFULLY IN THE MARKET FOR INTERNET AD MANAGEMENT AND
  DELIVERY SERVICES, WHICH WOULD ADVERSELY AFFECT OUR ABILITY TO RETAIN OUR
  EXISTING CUSTOMERS AND TO ATTRACT NEW CUSTOMERS
 
        The market for Internet ad management and delivery services is extremely
competitive, and we expect this competition to increase. Our ability to compete
successfully in this market depends on many factors, including:
 
        - the performance, reliability, ease of use and price of services that
          we or our competitors offer;
 
        - market acceptance of centralized, outsourced ad management and
          delivery systems as compared to internally-developed or site-specific
          software and hardware solutions;
 
        - our ability, relative to our competitors, to scale our technology
          infrastructure as our customer needs grow;
 
        - timeliness and market acceptance of new services and enhancements to
          existing services introduced by us or our competitors; and
 
        - customer service and support efforts by us or our competitors.
 
        The market for Internet ad management and delivery services is subject
to intense competition as companies attempt to establish a market presence. We
have in the past and may in the future be forced to reduce the prices for our
services in order to compete, which could materially and adversely affect our
net revenue and gross margins.
 
        We currently compete with providers of outsourced ad services, including
DoubleClick and MatchLogic, as well as providers of ad server software and
hardware solutions, such as NetGravity. Many of our current competitors have
substantially greater resources and more developed sales and marketing
strategies than we do. We may be unable to compete effectively against these
competitors now or in the future. In addition, several large Web sites possess
proprietary ad serving technologies and could decide to enter the market for
outsourced Internet advertising solutions. Barriers to entering the Internet
advertising market are relatively low. We may encounter new competitors that
have longer operating histories, greater name recognition, larger customer bases
or significantly greater financial, technical and marketing resources than we
do.
 
MANY OF OUR CUSTOMERS HAVE LIMITED OPERATING HISTORIES, ARE UNPROFITABLE AND MAY
  NOT BE ABLE TO PAY FOR OUR SERVICES, WHICH COULD ADVERSELY AFFECT OUR ABILITY
  TO RECOGNIZE REVENUE FROM THESE CUSTOMERS
 
        Many of our leading customers, including GeoCities, 24/7 Media and
Adsmart, have limited operating histories and have not achieved profitability.
If one or more of our customers is unable to pay for our services, or pays more
slowly than we anticipate, our quarterly and annual results of operations could
 
                                       8
<PAGE>
be materially and adversely affected. You should evaluate the ability of our
customers to meet their payment obligations to us in light of the risks,
expenses and difficulties encountered by companies with limited operating
histories, particularly in the evolving Internet market. In the past, some of
our customers have failed to pay for our services on a timely basis.
 
WE MAY EXPERIENCE SYSTEM FAILURES OR DELAYS THAT WOULD ADVERSELY AFFECT OUR
  OPERATIONS, WHICH COULD LEAD TO CUSTOMER DISSATISFACTION
 
        Our operations depend on our ability to protect our computer systems
against damage from fire, water, power loss, telecommunications failures,
computer viruses, vandalism and other malicious acts, and similar unexpected
adverse events. In the past, interruptions or slowdowns in our services have
resulted from the failure of our telecommunications providers to supply the
necessary data communications capacity in the time frame we require, as well as
from deliberate acts. Unanticipated problems affecting our systems could in the
future cause interruptions or delays in our services. Slow response times or
system failures could also result from straining the capacity of our software or
hardware due to an increase in the volume of advertising delivered through our
servers. Our customers may become dissatisfied by any system failure or delay
that interrupts our ability to provide service to them or slows our response
time.
 
WE MAY NOT BE ABLE TO TARGET ADVERTISEMENTS, WHICH COULD ADVERSELY AFFECT OUR
  ABILITY TO RETAIN OUR EXISTING CUSTOMERS AND TO ATTRACT NEW CUSTOMERS
 
        We may not be able to continue to meet the needs of our customers or the
marketplace for more sophisticated targeting solutions. As more advertisers
demand targeting solutions, we will need to develop increasingly effective tools
and larger databases that can provide greater demographic precision in ad
management and delivery. The development of these tools and databases is
technologically challenging and expensive. We cannot assure you that we can
develop any of these tools or databases in a cost-effective and timely manner,
if at all. Moreover, privacy concerns may cause a reduction or limitation in the
use of user information, which could limit the effectiveness of our technology
and adversely affect our ability to retain our existing customers and to attract
new customers.
 
THE INTERNET ADVERTISING MARKET MAY FAIL TO DEVELOP OR DEVELOP MORE SLOWLY THAN
  EXPECTED, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO RETAIN OUR EXISTING
  CUSTOMERS AND TO ATTRACT NEW CUSTOMERS
 
        The Internet advertising market may fail to develop or develop more
slowly than expected. Our future growth largely depends on the continued growth
in Internet advertising generally, and on the willingness of our potential
customers to outsource their Internet advertising and direct marketing needs.
Companies doing business on the Internet must compete with traditional media,
including television, radio, cable and print, for a share of advertisers' total
advertising budgets. Advertisers may be reluctant to devote a significant
portion of their advertising budgets to Internet advertising if they perceive
the Internet to be a limited or ineffective advertising medium.
 
        Substantially all of our revenue is derived from the delivery of
advertisements placed on Web sites. If advertisers determine that those ads are
ineffective or unattractive as an advertising medium, we may be unable to make
the transition to any other form of Internet advertising. Also, there are filter
software programs that limit or prevent advertising from being delivered to a
user's computer. The commercial viability of Internet advertising would be
materially and adversely affected by Internet users' widespread adoption of
these software programs.
 
THE INTERNET INFRASTRUCTURE MAY NOT BE ABLE TO ACCOMMODATE RAPID GROWTH, WHICH
  COULD ADVERSELY AFFECT OUR ABILITY TO RETAIN OUR EXISTING CUSTOMERS AND TO
  ATTRACT NEW CUSTOMERS
 
        The Internet infrastructure may fail to support the growth of the
Internet. If the Internet continues to experience an increase in users, an
increase in frequency of use or an increase in the capacity
 
                                       9
<PAGE>
requirements of users, we cannot assure you that the Internet infrastructure
will be able to support the demands placed on it. Any actual or perceived
failure of the Internet could undermine the benefits of our services. In
addition, the Internet could lose its viability as a commercial medium due to
delays in the development or adoption of new technology required to accommodate
increased levels of Internet activity or due to increased government regulation.
Changes in, or insufficient availability of, telecommunications services to
support the Internet could result in slower response times and could hamper use
of the Internet. Even if the Internet infrastructure is able to accommodate
rapid growth, we may be required to spend heavily to adapt to new technologies.
 
WE MAY NOT BE ABLE TO RETAIN KEY PERSONNEL, AND OUR MANAGEMENT TEAM MAY NOT WORK
  TOGETHER SUCCESSFULLY
 
        Our future success depends on the continued service of our key
technical, sales and senior management personnel and their ability to execute
our growth strategy. Recently, we have experienced significant changes in our
management team. One of our founders and former President, Chad Steelberg, who
originally developed some of our core technologies, left AdForce in November
1998. In addition, in January 1999 we hired three new executive officers. Our
future performance will depend, in part, on our ability to integrate our newly
hired executive officers effectively into our management team. Our executive
officers, who have worked together for only a short time, may not be successful
in carrying out their duties or making strategic decisions quickly in a rapidly
changing market.
 
WE MAY NOT BE ABLE TO MANAGE OUR GROWTH, WHICH COULD ADVERSELY AFFECT OUR
  ABILITY TO MANAGE OUR BUSINESS
 
        We have grown our workforce substantially, from 52 employees on March
31, 1998 to 109 employees on March 31, 1999, and we plan to continue to expand
our research and development, data center operations, sales, marketing and
customer service organizations. We may not be able to manage our internal growth
effectively to keep pace with the expansion of the Internet advertising market
or our competitors' growth. Our growth has placed, and the anticipated future
growth in our operations will continue to place, a significant strain on our
management systems and resources. We expect that we will need to continue to
improve our financial and managerial controls and reporting systems and
procedures, and will need to continue to expand, train and manage our workforce.
 
WE MAY NOT BE ABLE TO PROTECT OUR TECHNOLOGY, WHICH COULD DIMINISH THE VALUE OF
  OUR TECHNOLOGY AND OUR SERVICES
 
        Our success and ability to compete are dependent on our internally
developed technologies and trademarks. If our proprietary rights are infringed
by a third party, the value of our services to our customers would be diminished
and additional competition might result from the third party's use of those
rights. We cannot assure you that our patent applications or trademark
registrations will be approved. Even if they are approved, our patents or
trademarks may be successfully challenged by others or invalidated. If our
trademark registrations are not approved because third parties own those
trademarks, our use of these trademarks would be restricted unless we entered
into arrangements with the third-party owners, which might not be possible on
reasonable terms. We cannot assure you that any of our proprietary rights will
be viable or of value since the validity, enforceability and scope of protection
of proprietary rights in Internet-related industries are uncertain and evolving.
We also cannot assure you that the steps we have taken will prevent
misappropriation of our solutions or technologies, particularly in foreign
countries where laws or law enforcement practices may not protect our
proprietary rights as fully as in the United States.
 
                                       10
<PAGE>
THIRD PARTIES MAY ASSERT INFRINGEMENT CLAIMS AGAINST US OR OUR CUSTOMERS, WHICH
  COULD RESULT IN LIABILITY FOR DAMAGES, THE INVALIDATION OF OUR RIGHTS OR THE
  DIVERSION OF OUR TIME AND ATTENTION
 
        Third parties may assert infringement claims against us or our customers
based on our technology or our collection of user data. Any claims or
litigation, if they occur, could subject us to significant liability for damages
or could result in invalidation of our rights. Even if we were to prevail,
litigation could be time-consuming and expensive to defend, and could result in
diversion of our time and attention. Any claims or litigation from third parties
might also limit our ability to use the proprietary rights subject to these
claims or litigations.
 
OUR CONTRACTUAL RELATIONSHIP WITH AMERICA ONLINE COULD LEAD TO A DIVERSION OF
  OUR DEVELOPMENT RESOURCES AND THE OBLIGATION TO PAY AMERICA ONLINE A LARGE SUM
  OF MONEY
 
        We have granted to America Online and its affiliates a royalty-free,
perpetual license to our ad management and delivery technology, including source
and object code, and any improvements to it that we make generally available to
our customers. Under the terms of this license agreement, America Online could
also require us to customize a version of our technology for the exclusive use
of America Online and its affiliates. We are obliged under the license agreement
to provide these services for an indefinite period of time with little potential
for significant profit, which could significantly strain our development
resources. We have also entered into a demographic data agreement with America
Online. Under the terms of this agreement, America Online may elect to make
demographic information available to us at any time within three years,
triggering substantial payment obligations from us even if we do not use this
information and even if we have contracted to obtain similar information from an
alternative source. If America Online makes the demographic data available to us
and then later limits or denies access to the demographic information or
significantly changes its advertising or privacy policies, our ability to market
our technology and services with enhanced targeting abilities and to generate
additional revenue could be severely limited. Please see "Related Party
Transactions" for detailed information on our relationship with America Online.
 
GOVERNMENT REGULATION OF THE INTERNET MAY INHIBIT THE COMMERCIAL ACCEPTANCE OF
  INTERNET
 
        New legislation regulating the Internet could inhibit the growth of the
Internet and decrease the acceptance of the Internet as a communications and
commercial medium. The applicability to the Internet of existing laws governing
issues such as property ownership, libel and personal privacy is uncertain.
Governmental authorities may seek to further regulate the Internet with respect
to issues such as user privacy, pornography, acceptable content, electronic
commerce, taxation, and the pricing, characteristics and quality of products and
services.
 
POTENTIAL YEAR 2000 RISKS MAY ADVERSELY AFFECT OUR BUSINESS
 
        There is significant uncertainty in the software industry regarding the
potential effects associated with Year 2000 compliance issues. We have not
engaged in any official process designed to independently verify our Year 2000
readiness or to assess potential costs associated with Year 2000 risks, nor have
we made any contingency plans to address these risks. We cannot assure you that
unanticipated costs associated with any Year 2000 compliance will not exceed our
present expectations.
 
        We depend heavily on the uninterrupted availability of the Internet
infrastructure to conduct our business as a centralized management and delivery
service. We also rely heavily on the continued operations of our customers, in
particular Web sites hosting advertisements, for our revenue. We are thus
dependent upon the success of the Year 2000 compliance efforts of the many
service providers that support the Internet, and the Year 2000 compliance
efforts of our customers. Interruptions in the Internet infrastructure affecting
us or our customers, or the failure of the Year 2000 compliance efforts of one
or more of our customers, could have a material adverse effect on our quarterly
and annual results of
 
                                       11
<PAGE>
operations. Please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000 Compliance" for detailed
information on our Year 2000 readiness.
 
WE MAY NOT HAVE ENOUGH CAPITAL TO EXECUTE OUR BUSINESS OBJECTIVES, WHICH COULD
  ADVERSELY AFFECT OUR ABILITY TO MEET OUR FINANCIAL PROJECTIONS OR THOSE OF
  SECURITIES ANALYSTS
 
        We may need to raise additional funds, and we cannot be certain that we
would be able to obtain additional financing on favorable terms, if at all. We
are devoting at least an additional $9.0 million to our data center facilities
in Costa Mesa and Cupertino, California during the remainder of 1999, and will
need to devote additional resources as we establish new ad management and
delivery centers. We also expect to make significant investments in sales and
marketing and the development of new services. The failure to generate
sufficient cash flows or to raise sufficient funds to finance growth could
require us to delay or abandon some or all of our plans or forego new market
opportunities, making it difficult for us to respond to competitive pressures.
If we issue equity securities to raise funds, our stockholders will be diluted.
The holders of the new equity securities may also have rights, preferences or
privileges senior to those of existing holders of common stock.
 
THE PRICE OF OUR COMMON STOCK IS LIKELY TO BE VOLATILE AND SUBJECT TO WIDE
  FLUCTUATIONS, AND WE COULD BE SUBJECT TO SECURITIES LITIGATION
 
        The market price of our common stock is likely to be subject to wide
fluctuations. If our revenue does not grow or grows more slowly than we
anticipate, or if operating or capital expenditures exceed our expectations or
cannot be adjusted accordingly, the market price of our common stock could fall.
In addition, if the market for Internet-related stocks or the stock market in
general experiences a loss in investor confidence, the market price of our
common stock could fall for reasons unrelated to our business or results of
operations. Investors may be unable to resell their shares of our common stock
at or above the offering price. In the past, companies that have experienced
volatility in the market price of their stock have been the subject of
securities class action litigation. If we were the subject of litigation, it
could result in substantial costs and a diversion of management's attention and
resources.
 
AN ACTIVE PUBLIC MARKET FOR OUR COMMON STOCK MAY NOT DEVELOP, WHICH COULD
  ADVERSELY AFFECT YOUR ABILITY TO SELL YOUR SHARES AND THE MARKET PRICE OF YOUR
  SHARES
 
        Before this offering, you could not buy or sell our common stock on a
public market. An active public market for our common stock may not develop or
be sustained after the offering, which could affect your ability to sell your
shares and depress the market price of your shares. The market price of your
shares may significantly vary from the offering price.
 
PROVISIONS IN OUR CHARTER DOCUMENTS MAY DETER ACQUISITION BIDS FOR ADFORCE,
  WHICH COULD ADVERSELY AFFECT THE MARKET PRICE OF YOUR SHARES
 
        We have adopted a classified board of directors. In addition, our
stockholders are unable to act by written consent or to fill any vacancy on the
board of directors. Our stockholders cannot call special meetings of
stockholders to remove any director or the entire board of directors without
cause. These provisions and other provisions of Delaware law could make it more
difficult for a third party to acquire us, even if doing so would benefit our
stockholders. Please see "Management" and "Description of Capital Stock" for
detailed information on these protective provisions.
 
OUR OFFICERS AND DIRECTORS EXERT SUBSTANTIAL INFLUENCE OVER ADFORCE, WHICH COULD
  LIMIT YOUR ABILITY TO INFLUENCE ADFORCE AND WHICH COULD DELAY OR PREVENT A
  CHANGE OF CONTROL OF ADFORCE
 
        We anticipate that our executive officers, our directors and entities
affiliated with them and our 5% stockholders will beneficially own, in the
aggregate, approximately 56.4% of our outstanding common
 
                                       12
<PAGE>
stock following the completion of this offering. These stockholders may be able
to exercise substantial influence over all matters requiring approval by our
stockholders, including the election of directors and approval of significant
corporate transactions. This concentration of ownership may also have the effect
of delaying or preventing a change in control of AdForce.
 
FUTURE SALES OF SHARES BY EXISTING STOCKHOLDERS COULD ADVERSELY AFFECT THE
  MARKET PRICE OF YOUR SHARES
 
        Sales of a substantial number of shares of our common stock in the
public market by our stockholders after this offering could depress the market
price of our common stock and could impair our ability to raise capital through
the sale of additional equity securities. Please see "Shares Eligible for Future
Sale" for a description of shares of our common stock that are available for
future sale.
 
                           FORWARD-LOOKING STATEMENTS
 
        Some of the statements under the captions "Prospectus Summary," "Risk
Factors," "Use of Proceeds," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere in this

include statements about our plans, objectives, expectations and intentions and
other statements contained in the prospectus that are not historical facts. When
used in this prospectus, the words expects, anticipates, intends, plans,
believes, seeks and estimates and similar expressions are generally intended to
identify forward-looking statements. Because these forward-looking statements
involve risks and uncertainties, there are important factors that could cause

                                USE OF PROCEEDS
    
 
   
        The net proceeds to us from the sale of the 4,500,000 shares of common
stock offered by us will be approximately $61,675,000, at the initial public
offering price of $15.00 per share and after deducting underwriting discounts
and commissions and the estimated offering expenses. If the underwriters' over-
allotment option is exercised in full, our net proceeds will be approximately
$71,091,250.
    
 
        We intend to use the net proceeds from this offering primarily for
general corporate purposes, including working capital. We may also use a portion
of the net proceeds from this offering to acquire or invest in businesses,
technologies or services that are complementary to our business. We have no
present plans or commitments and are not engaged in any negotiations with
respect to any transactions of this type. Pending these uses, we intend to
invest the net proceeds from this offering in short-term, interest-bearing,
investment-grade securities. Please see "Risk Factors--We May Not Have Enough
Future Capital to Execute Our Business Objectives, Which Could Adversely Affect
Our Ability to Meet Our Financial Projections or Those of Securities Analysts."
 
                                DIVIDEND POLICY
 
        We have never declared or paid any cash dividends on shares of our
capital stock. We intend to retain any future earnings to finance future growth
and do not anticipate paying any cash dividends in the future.

                                    DILUTION
 
   
        The pro forma net tangible book value of AdForce as of March 31, 1999
was $5.6 million, or $0.38 per share of common stock. Pro forma net tangible
book value per share represents the amount of AdForce's total tangible assets
less total liabilities, divided by 14,669,429 shares of common stock outstanding
after giving effect to the conversion of all outstanding shares of preferred
stock into shares of common stock upon completion of this offering. After giving
effect to the receipt of the net proceeds from the sale of the 4,500,000 shares
of our common stock at the initial public offering price of $15.00 per share and
after deducting underwriting discounts and commissions and the estimated
offering expenses, the pro forma net tangible book value of AdForce as of March
31, 1999 would have been approximately $67.2 million, or $3.51 per share. This
represents an immediate increase in pro forma net tangible book value of $3.13
per share to existing stockholders and an immediate dilution of $11.49 per share
to new investors purchasing shares at the initial public offering price. The
following table illustrates the per share dilution:

        The above discussion and tables assume no exercise of any stock options
or warrants outstanding as of March 31, 1999. As of March 31, 1999, there were
options and warrants outstanding to purchase a total of 3,575,445 shares of
common stock with a weighted average exercise price of $2.96 per share. If any
of these options or warrants are exercised, there will be further dilution to
new public investors. Please see "Capitalization," "Management-- Employee

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
        AdForce is a leading provider of centralized, outsourced ad management
and delivery services on the Internet. We began operations on January 16, 1996
as Imgis, Inc. and spent the first 15 months of our operations developing
technology that could be used to manage and deliver Internet ads for
advertisers, ad agencies, Web sites and ad rep firms. Initially, we did not have
an internal sales force dedicated to selling our services. To generate business,
we relied primarily on the sales forces of ad rep firms that used our services
to manage and deliver ads to the Web site customers they represented. In
December 1997, we began to build a direct sales force to allow us to penetrate
the market for our services more effectively.
 
   
        We began delivering ads and recognizing revenue during the second
quarter of 1997, and increased our revenue as the ad volumes delivered by our ad
rep firm customers grew. 24/7 Media and its predecessor firms were responsible
for 92% of our net revenue in 1997. In November 1997, we also contracted to
deliver ads for Netcom and FortuneCity, and began to demonstrate the
applicability of our services to Web sites. In 1998, we continued to add
customers with material amounts of ad volume. Adsmart and Netscape began using
our services in early 1998, and GeoCities began using our services in the latter
half of June 1998. Though we continue to derive the majority of our net revenue
from a limited number of customers, we broadened our customer base in 1998. In
the first quarter of 1998, Petry Interactive and Katz Millenium, which are now
part of 24/7 Media, accounted for 76% and 14% of our net revenue. By the first
quarter of 1999, our top four customers, 24/7 Media, Adsmart, GeoCities and
Netscape, accounted for 23%, 21%, 20% and 12% of our net revenue. 24/7 Media has
stated that it is currently developing a next generation ad delivery technology
that is intended to serve as its sole ad delivery solution. It has also stated
that, unless and until the development of and transition to its own ad delivery
technology is complete, it will be primarily dependent on us to deliver ads to
its networks and Web sites.
    
 
        In 1997 and 1998, we earned the vast majority of our revenue by managing
and delivering ads for ad agencies, Web sites and ad rep firms. We intend to
begin marketing our services to advertisers during 1999. We also charged
customers for other services, such as developing custom reports, although
revenue to date from these services has not been significant. We plan to
continue to develop and offer new services, such as advanced consumer targeting
capabilities, and expect that an increasing proportion of our revenue will be
generated by these services.
 
        We charge our customers based on each 1,000 ads delivered. Customers
with higher expected ad volumes than average generally are charged a lower rate
on each 1,000 ads delivered. During 1998, the monthly volume of ads we delivered
increased significantly as Internet traffic increased and we gained market
share. However, the average rate we charged declined during 1998. We believe
that pricing competition and lower rates charged to higher-volume customers were
the primary reasons for this decline. We expect those factors to cause future
declines in average rates charged.
 
        We believe our centralized ad management system is substantially less
expensive than on-site ad delivery alternatives available to most individual Web
sites. Our average cost to manage and deliver each ad is significantly
influenced by the ad volume moving through our system. As we continue to
aggregate Web sites and their ad volumes on our system, and add additional
advertisers, ad agencies and ad rep firms as customers, we expect the average
cost to deliver each ad to generally decline. In the second quarter of 1999, we
opened our second data center, potentially increasing our costs to deliver each
ad during the next 12 months. In addition, a portion of our research and
development efforts is devoted to improving the performance and efficiency of
our systems. We believe that these favorable economies for centralized ad
management will increase if greater and greater ad volumes are delivered by our
system.
 
                                       18
<PAGE>
During 1998, the average cost to deliver each ad declined more significantly
than the decrease in the average rate charged, resulting in steadily improving
gross margins.
 
        In the operating areas of research and development, marketing and
selling, and general and administrative costs, the single most significant cost
is personnel, including the related payroll, facilities and other overhead
costs. Historically, our personnel requirements in these operating areas have
increased at significantly lower rates than revenue.
 
   
        We have recorded deferred stock compensation for options granted after
January 1998. As of March 31, 1999, we had recorded aggregate deferred stock
compensation of $8.1 million. This deferred stock compensation is being
amortized over the vesting periods of the stock options. AdForce recognized a
total of $1.2 million and $1.1 million in stock compensation expense during 1998
and the three months ended March 31, 1999. In addition, we recorded stock
compensation expense of $1.4 million during 1998 related to unvested founders'
stock that was not repurchased. Since a portion of this expense was related to
persons involved in running our data center operations, we allocated that
portion to cost of revenue and thus reduced our gross margin. The total charges
to be recognized in future periods from amortization of deferred stock
compensation as of March 31, 1999 are anticipated to be approximately $2.8
million, $1.9 million, $900,000 and $200,000 for the remaining nine months of
1999 and for 2000, 2001 and 2002. In addition to these charges, we expect to
record an additional $4.4 million of deferred stock compensation in April and
May 1999, which will be amortized over the vesting periods of the related
options.
    
 
   
        In February 1998, AdForce acquired StarPoint Software, Inc., principally
by exchanging AdForce shares for StarPoint shares. We accounted for this
transaction as a purchase with a total purchase price of $4.1 million. The
purchase price was primarily allocated to intangible assets, including purchased
technology of $2.6 million, personnel-related assets of $740,000, and goodwill
of $609,000, which are being amortized over the respective lives of those
assets, and in-process technology of $100,000 that was expensed at the time of
the acquisition. Amortization charges of $1,329,000 related to this purchase
were recognized during 1998, and further amortization charges of $1,446,000,
$1,107,000 and $66,000 are expected to be recognized in 1999, 2000 and 2001.
    
 
   
        We incurred net losses of $3.5 million for the period from January 16,
1996 (inception) to December 31, 1996, $5.7 million for the year ended December
31, 1997, $15.6 million for year ended December 31, 1998, and $5.0 million for
the three months ended March 31, 1999. As of March 31, 1999, our accumulated
deficit was $29.8 million. We expect to continue to incur significant operating
expenditures, and capital expenditures of at least $9.0 million, for the
remainder of 1999. As a result, we will need to generate significantly greater
revenue than we have generated to date to achieve and maintain profitability. In
addition, our operating costs are relatively fixed, and cannot be quickly
lowered even if we fail to generate significant revenue. Although we have
experienced significant growth in revenue in recent periods, we expect the
growth rate to decline substantially. We expect to continue to incur net losses
on a quarterly and annual basis for at least the next two years.

NET REVENUE
 
        We experienced revenue growth in each quarter of 1998 and the first
quarter of 1999. When compared to the immediately preceding quarter, quarterly
net revenue grew by 97%, 89%, 36%, 90% and 59% during the first, second, third
and fourth quarters of 1998 and the first quarter of 1999. The increases in net
revenue for all periods presented were primarily due to increases in the volumes
of ads that we delivered on behalf of our customers, partially offset by
declines in the average rates charged for delivering those ads. The ad volume
increases resulted from both the addition of new customers and the growth in ad
volumes experienced by many of our existing customers as the market for Internet
advertising increased. The declines in average rates charged were primarily the
result of competitive pricing pressure and lower rates charged to higher-volume
customers. In 1998, we added several large customers with significant ad
volumes. We expect pricing pressure from competitors and discounts related to
large-contract pricing to continue for at least the next several quarters.
 
        The growth in net revenue between the first and second quarters of 1998
was due primarily to increased ad volumes delivered for 24/7 Media and, to a
lesser extent, to significant ad volume increases from Fortune City and several
new ad agency and Web site customers. The growth in net revenue between the
second and third quarters of 1998 was largely due to the revenue contribution of
GeoCities, which became a customer in late June 1998, and of ad agencies and
other Web sites that became customers during the third quarter. The increase in
net revenue from these customers in the third quarter was partially offset by a
decline in net revenue from 24/7 Media, as it moved a portion of its ad volume
from our systems to its own proprietary server. The revenue growth rate from the
second to the third quarter was significantly less than the revenue growth rate
in previous quarters as we encountered issues in transitioning GeoCities from
its own on-site ad server to our service, AdForce for Publishers, causing them
to revert to their existing on-site ad server for the month of August 1998. The
issues were resolved and GeoCities resumed using our centralized service in
September 1998. As a result, our quarterly revenue growth rate in the fourth
quarter returned to earlier levels. The growth in net revenue between the third
and fourth quarters of 1998 was due to significantly greater net revenue from
GeoCities, from 24/7 Media as it began to move ad volume from its proprietary
server back to the AdForce service, and from Netscape and other customers.
Although Netscape became a customer in the first quarter of 1998, it did not
generate significant revenue for us until the fourth quarter of 1998. The growth
in net revenue between the fourth quarter of 1998 and the first quarter of 1999
was due to increases in revenue from 24/7 Media, Netscape, Adsmart and MapQuest.
The increases in revenue were the result of increased ad volumes. The increase
in ad volumes was partially offset by a decrease in the average rate charged to
deliver 1,000 ads. We expect that future revenue growth, if any, will not be as
dramatic as in recent periods. 24/7 Media has stated that it is currently
developing a next generation ad delivery technology that is intended to serve as
its sole ad delivery solution. It has also stated that, unless and until the
development of and transition to its own ad delivery technology is complete, it
will be primarily dependent on us to deliver ads to its networks and Web sites.
 
        Our net revenue increased from $320,000 in 1997 to $4.3 million in 1998,
and was $3.2 million in the first quarter of 1999. We had no revenue in 1996.
The increases in net revenue were primarily due to the increased number of ads
that we served on behalf of our customers, offset in part by a decline in the
average rates charged for serving these ads. The increase in ad volume resulted
both from the addition of new customers and from increasing ad volumes for
existing and new customers. The decline in the average rates charged resulted
from significant pricing pressure from competitors and volume-based pricing
discounts.
 
        Our net revenue increased from $414,000 in the first quarter of 1998 to
$3.2 million in the first quarter of 1999. This increase in net revenue was
primarily due to the increased number of ads that we delivered on behalf of our
customers, offset in part by a decline in the average rates charged for
delivering these ads. The increase in ad volume resulted both from the addition
of new customers and from
 
                                       21
<PAGE>
increasing ad volumes for existing and new customers. The decline in the average
rates charged resulted from significant pricing pressure from competitors and
lower rates charged to higher-volume customers.
 
GROSS PROFIT (LOSS)
 
   
        Gross margin increased sequentially from negative 117% in the first
quarter of 1998 to negative 95% in the second quarter of 1998 to negative 26% in
the third quarter of 1998 to positive 13% in the fourth quarter of 1998 and to
positive 29% in the first quarter of 1999. Although our average rates charged
declined during 1998 and the first quarter of 1999 as a result of competition
and discounts to customers with large ad volumes, our average cost to manage and
deliver ads declined at a faster pace. Our average cost to manage and deliver
each ad is significantly influenced by ad volume moving through our system. When
a larger number of ads is delivered, the average cost to deliver each ad
declines. In addition, a portion of our research and development efforts is
devoted to more efficient design and deployment of capital assets used in
managing and delivering ads. As the results of these efforts are integrated into
the AdForce system, we expect fewer resources will be required to deliver the
same number of ads and the average cost to deliver each ad will generally
decline, although on a quarterly basis these costs may fluctuate. In April 1999,
we opened our second data center to provide additional capacity and operational
redundancy. The expenses associated with operating this second data center will
increase cost of revenue, and, as such, will have a negative impact on gross
margin in future periods.
    
 
        Total cost of revenue primarily consists of capital asset costs,
telecommunications costs, facilities costs and personnel-related costs incurred
to operate our data center. It also includes non-cash charges for amortization
of deferred stock compensation to data center personnel who received options
with exercise prices below the fair market value of the underlying shares on the
date of grant, as well as charges for amortization of an intangible asset
acquired in the purchase of StarPoint. The related intangible asset was
technology that has been deployed in our ad delivery system. This asset is being
amortized over its estimated useful life of three years.
 
   
        Our gross margin was negative 371% in 1997, negative 29% in 1998 and
positive 29% in the first quarter of 1999. The improvement in gross margin from
1997 to 1998 to the first quarter of 1999 was primarily due to increased revenue
resulting from increased ad volumes and an improved technology infrastructure
that allowed us to deploy our resources to deliver ads more efficiently. These
efficiency improvements were offset in part by declining average rates charged
to our customers.
    
 
RESEARCH AND DEVELOPMENT EXPENSES
 
        Research and development expenses consist primarily of personnel and
related costs associated with developing technology, primarily software, for use
in providing our services to customers. These expenses increased sequentially
each quarter from the first quarter of 1998 to the first quarter of 1999, as
personnel were added to enhance the features and performance of our services. In
the fourth quarter of 1998 and the first quarter of 1999, we also incurred
consulting costs in connection with a review of our technology to identify
potential ways to enhance future performance and reliability. Our research and
development expenses were $1.6 million in 1996, $2.2 million in 1997, $4.7
million in 1998 and $2.2 million in the first quarter of 1999. These expenses
increased primarily as a result of growth in the number of research and
development employees and, to a lesser extent, as a result of increases in
capital assets and facility expenses incurred to develop the software used to
deliver ads. We expect our research and development expenses to increase in
absolute dollars over the next several quarters.
 
MARKETING AND SELLING EXPENSES
 
        Our marketing and selling expenses during 1998 and the first quarter of
1999 consisted primarily of personnel and related costs, as well as costs for
promotional activities associated with raising brand awareness. In 1998 and the
first quarter of 1999, marketing and selling expenses increased across all
 
                                       22
<PAGE>
quarters presented, reflecting our decision, late in the fourth quarter of 1997,
to establish a direct sales force and to increase brand awareness through
marketing efforts. As a result, we significantly increased the number of our
sales and marketing employees and our promotional events, and greatly expanded
our capital asset base and facilities dedicated to marketing and selling
activities. We incurred no direct selling expenses in 1996 or in 1997, and our
marketing expenses in those periods consisted primarily of personnel and related
costs for the indirect marketing of our services. In 1996, $954,000 of marketing
expenses represented payments for key word rights on certain Web sites under a
marketing plan that was abandoned late in 1996.
 
        Our marketing and selling expenses were $1.5 million in 1996, $1.1
million in 1997, $4.9 million in 1998 and $1.8 million in the first quarter of
1999. The decline in marketing and selling expenses from 1996 to 1997 was
primarily the result of the absence in 1997 of expenses related to key word
rights that was recorded in 1996. The increase in marketing and selling expenses
from 1997 to 1998 to the first quarter of 1999 resulted primarily from our
decision late in the fourth quarter of 1997 to establish a direct sales force
and to increase market awareness through substantial marketing efforts. We
expect our marketing and selling expenses to increase in absolute dollars over
the next several quarters.
 
GENERAL AND ADMINISTRATIVE EXPENSES
 
        Our general and administrative expenses consist primarily of personnel
and related costs associated with providing executive, financial and legal
support to AdForce, in addition to other costs typically associated with
providing corporate infrastructure. General and administrative expenses
increased in each of the first three quarters of 1998, reflecting increases in
personnel and related costs. In the third quarter of 1998, a $59,000 charge was
made to general and administrative expenses in connection with the settlement of
a claim made by a former officer of AdForce. Since no similar charge occurred in
the fourth quarter, general and administrative expenses were lower in the fourth
quarter of 1998 than in the third quarter of 1998. General and administrative
expenses in the first quarter of 1999 were higher than those in the first
quarter of 1998. Our general and administrative expenses were $337,000 in 1996,
$1.1 million in 1997, $1.8 million in 1998 and $615,000 in the first quarter of
1999. These increases were primarily the result of increased personnel and
infrastructure to address the requirements of increased business volume. We
expect our general and administrative expenses to increase in absolute dollars
over the next several quarters.
 
AMORTIZATION OF INTANGIBLE ASSETS AND DEFERRED STOCK COMPENSATION
 
        In each of the four quarters of 1998 and in the first quarter of 1999,
we recognized expense for the amortization of deferred stock compensation to
personnel who had been granted options with an exercise price deemed to be below
the fair market value of the underlying common stock on the date of grant for
financial reporting purposes. In connection with our acquisition of StarPoint in
February 1998, intangible assets are being amortized to operations over the
lives of those assets. In addition, approximately $100,000 of the initial
consideration was allocated to the value of purchased in-process technology.
This purchased in-process technology had not achieved technological feasibility
at the time of the acquisition and, therefore, did not qualify for
capitalization under generally accepted accounting principles. Accordingly, the
portion of the purchase price allocated to purchased in-process technology was
charged to operations in the first quarter of 1998.
 
INTEREST EXPENSE, NET
 
        Interest expense, net was $69,000 in 1996, $108,000 in 1997, $151,000 in
1998 and $73,000 in the first quarter of 1999. In each period, interest expense
resulted primarily from interest on bridge financings and capital equipment
leases, offset in part in 1997, 1998 and the first quarter of 1999 by interest
income earned on cash balances resulting from equity and capital lease
financings.
 
                                       23

FLUCTUATIONS IN RESULTS OF OPERATIONS
 
        Our quarterly results of operations have varied in the past, and you
should not rely on quarter-to-quarter comparisons of our results of operations
as an indication of our future performance. It is likely that in future periods
our results of operations will be below the expectations of public market
analysts and investors. In this event, the price of our common stock would
likely decline. Our revenue and results of operations depend on a variety of
factors, many of which are beyond our control. These factors include:
 
        - the timing and costs of improvements in our ad management and delivery
          infrastructure, including the addition of more capacity;
 
        - our ability to satisfy and retain our existing customers;
 
        - any loss of existing customers due to consolidation in the industry;
 
        - the ability of our existing customers to maintain or increase their
          Internet traffic or market share;
 
        - our ability to expand our customer base and the timing of new
          customers commencing service with us;
 
        - changes in our pricing policies or those of our competitors resulting
          from competitive pressures;
 
        - our ability to provide reliable and scalable service, including our
          ability to avoid potential system failures;
 
        - the announcement or introduction of new technology or services by us
          or our competitors, including database marketing capabilities;
 
        - seasonal trends in our business; and
 
        - general economic and market conditions.
 
        We anticipate making significant capital expenditures as we increase the
capacity and reliability of our existing technology infrastructure and data
center. We also intend to open additional ad management and delivery centers in
the future. The addition of these centers may increase the average cost to
deliver ads. In addition, we intend to increase our sales and marketing
operations and to continue to allocate a large portion of our budget for
research and development. We would likely be unable to adjust spending quickly
enough to offset any unexpected revenue shortfall. If we have a shortfall in
revenue in relation to our costs and expenses, then our business and quarterly
and annual results of operations would be materially and adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
        Since inception, we have financed our operations primarily from sales of
preferred stock and capital lease financings and, to a significantly lesser
extent, net proceeds from the issuance of notes payable and proceeds from sales
of common stock.
 
        Net cash used in operating activities was $2.3 million in 1996, $5.6
million in 1997, and $9.6 million in 1998. Net cash provided by operating
activities was $348,000 in the first quarter of 1999. In each annual period,
cash used in operating activities resulted primarily from our net loss, offset
partially by non-cash charges for depreciation and amortization and, in 1998,
also offset partially by amortization of intangible assets and deferred stock
compensation. In the first quarter of 1999, cash provided by operating
activities resulted primarily from increases in deferred revenue and accounts
payable. The increase in deferred revenue was due to a cash prepayment by a
large customer for ad management and delivery services to be provided while the
increase in accounts payable related to the general increase in business
volumes, as well as increased payables to outside professional service providers
related to our initial public
 
                                       24
<PAGE>
offering. Net cash used in investing activities was $1.4 million in 1996,
$163,000 in 1997, $1.2 million in 1998 and $343,000 in the first quarter of
1999. In each period, net cash used in investing activities was primarily the
result of capital expenditures for equipment used in operating our primary data
center from which ads are managed and delivered.
 
        Net cash provided by financing activities was $4.3 million in 1996, $6.7
million in 1997, $19.1 million in 1998. Net cash used in financing activities
was $323,000 in the first quarter of 1999. In 1996, net cash provided by
financing activities resulted primarily from net proceeds from the issuance of
preferred stock and notes payable. In 1997, net cash provided by financing
activities resulted primarily from net proceeds from the issuance of preferred
stock and proceeds from a sale-leaseback transaction. In 1998, net cash provided
by financing activities resulted primarily from net proceeds from the issuance
of preferred stock and notes payable, offset slightly, by principal payments on
capital lease obligations. In the first quarter of 1999, cash used in financing
activities was the result of payments on capital lease obligations, partially
offset by proceeds received from the issuance of common stock.
 
        At March 31, 1999, our principal sources of liquidity were $9.7 million
of cash and cash equivalents and $2.8 million of availability under an equipment
lease line. At that date, we had commitments of $132,000 for capital
expenditures. These commitments are primarily related to equipping a second data
center and to existing facilities expansion. We expect capital expenditures to
be approximately $9.0 million through the remainder of 1999 and at least $14.0
million in 2000. These expenditures will be primarily for computer hardware and
software, office furniture and equipment, and leasehold improvements. A
significant portion of the equipment may be acquired under capital leases. At
March 31, 1999, we had minimum lease payment obligations, including interest, of
$9.1 million under capital leases and $11.6 million under operating leases. We
will also have to pay America Online quarterly fees totaling at least $10.0
million for the first three years after they give us access to demographic data
specified in our demographic data agreement with America Online. We are
uncertain as to when, if ever, the demographic data may be made available to us.
 
        We believe that our existing cash and cash equivalents, and the net
proceeds from this offering will be sufficient to fund our operating activities,
capital expenditures and other obligations for at least the next 12 months.
However, if we are not successful in raising capital when we need it and on
terms acceptable to us, it could have a material adverse effect on our business,
results of operations and financial condition. If additional funds are raised
from the issuance of equity securities, the percentage ownership of our
stockholders would be reduced.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
        In March 1998, the American Institute of Certified Public Accountants
issued SOP No. 98-1, "ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR
OBTAINED FOR INTERNAL USE." SOP No. 98-1 requires entities to capitalize costs
related to internal-use software once specified criteria have been met. We
adopted SOP No. 98-1 beginning January 1, 1999. The adoption of SOP No. 98-1 did
not have a material impact on our financial position or results of operations.
 
        In April 1998, the AICPA issued SOP No. 98-5, "REPORTING ON THE COSTS OF
START-UP ACTIVITIES." SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, all start-up costs
that were capitalized in the past must be written off when SOP No. 98-5 is
adopted. We adopted SOP No. 98-5 beginning January 1, 1999. The adoption of SOP
No. 98-5 did not have a material impact on our financial position or results of
operations.
 
        In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 133, "ACCOUNTING FOR DERIVATIVE
INSTRUMENTS AND HEDGING ACTIVITIES." SFAS No. 133 establishes methods for
derivative financial instruments and hedging activities related to those
instruments, as well as other hedging activities. We will be required to
implement SFAS No. 133 for the year ending December 31, 2000. Because we do not
currently hold any derivative instruments and do not
 
                                       25
<PAGE>
engage in hedging activities, we do not expect that the adoption of SFAS No. 133
will have a material impact on our financial position or results of operations.
 
YEAR 2000 COMPLIANCE
 
        Many computer systems and software products are coded to accept only two
digit entries in the date code field. These date code fields will need to accept
four-digit entries to distinguish between 21(st) century and 20(th) century
dates. As a result, many companies' software and computer systems may need to be
upgraded or replaced to comply with these Year 2000 requirements.
 
        In the ordinary course of our business, we have evaluated the internally
developed software included in our ad management and delivery system, and
believe that this software is generally Year 2000 compliant, meaning that the
use or occurrence of dates on or after January 1, 2000 will not materially
affect the performance of this software or the ability of this software to
correctly create, store, process and output data involving dates. In the third
quarter of 1999, we intend to implement internal Year 2000 testing procedures
for our software, and we may learn that our software does not contain all of the
necessary software routines and codes necessary for the accurate calculation,
display, storage and manipulation of data involving dates. We expect the costs
associated with these testing procedures to be approximately $250,000. We have
warranted to some of our customers that Year 2000 compliance issues will not
adversely affect the performance of our ad management and ad delivery services.
If our customers experience Year 2000 problems with our services, they could
assert claims against us for damages. Our standard service agreements provide
performance warranties, and we may need to incur costs to address Year 2000
problems that our customers encounter through the use of our services. To date
we have not received any Year 2000 related claims regarding our services.
 
        We are also working with our external suppliers and service providers
with respect to both third-party applications in our ad management and delivery
system and third-party applications in our information technology infrastructure
to ensure that these third-party systems and applications will be able to
interoperate with our hardware and software infrastructure where necessary and
support our needs into the year 2000. We typically use industry-standard
third-party hardware and software. Where possible, we have sought assurances
from our suppliers that we believe are critical to our business that their
products are Year 2000 compliant. While we have received assurances as to the
Year 2000 compliance of some of these third-party products, we generally do not
have any contractual rights with these providers if their software or hardware
fails to function due to Year 2000 issues. If these failures do occur, we may
incur unexpected expenses to remedy any problems, including purchasing
replacement hardware and software.
 
        Though we will continue these efforts, we do not believe we have
significant Year 2000 issues within our systems or services. Because we believe
we are Year 2000 compliant, we have not engaged any third parties to
independently verify our Year 2000 readiness, nor have we assessed potential
costs associated with Year 2000 risks or made any contingency plans to address
these risks. Further, we have not deferred any of our ongoing development
efforts to address Year 2000 issues. However, unanticipated costs associated
with any Year 2000 compliance may exceed our present expectations, which could
materially and adversely affect our quarterly and annual results of operations.
 
        We depend on the uninterrupted availability of the Internet
infrastructure to conduct our business as a centralized ad delivery and
management service. We also rely on the continued operations of our customers,
in particular Web sites hosting advertisements, for our revenue. We are heavily
dependent upon the success of Year 2000 compliance efforts of the many service
providers that support the Internet, and the Year 2000 compliance efforts of our
customers. Interruptions in the Internet infrastructure affecting us or our
customers, or failure of the Year 2000 compliance efforts of one or more of our
customers, could materially and adversely affect our ability to generate
revenue. The purchasing patterns of advertisers and agencies could be affected
by Year 2000 issues as companies expend significant resources to correct their
current systems for the year 2000; these expenditures may result in reduced
funds available for Internet advertising, which could in turn materially and
adversely affect our ability to generate revenue.

        During 1998, we delivered 13.6 billion ads with increasing quarterly ad
volumes of 0.9 billion, 1.6 billion, 3.2 billion and 7.9 billion. We delivered
13.2 billion ads in the first quarter of 1999. Our net revenue increased
sequentially from $414,000 in the first quarter of 1998 to $3.2 million in the
first quarter of 1999. Through relationships with key customers, including 24/7
Media, Adsmart, GeoCities, Netscape and ModemMedia.PoppeTyson, we have achieved
a broad reach over the Internet. According to Media Metrix, an Internet research
firm, in December 1998 AdForce served ads to approximately 58% of U.S. Internet
users.
 
INDUSTRY BACKGROUND
 
    EMERGENCE OF THE INTERNET AS AN ADVERTISING MEDIUM
 
        The Internet has emerged as an important mass medium for advertising and
direct marketing, communication and electronic commerce. International Data
Corporation, a firm specializing in online research and analysis, estimates that
Internet users numbered approximately 100 million in 1998 and will grow to more
than 320 million in 2002. Rapid expansion of the Internet has led to significant
growth in electronic commerce. IDC estimates that purchases of goods and
services over the Internet will increase from $32 billion in 1998 to $426
billion in 2002. Growth of the Internet generally and of electronic commerce in
particular has spurred traditional businesses to devote larger portions of their
marketing budgets to Internet advertising, and has prompted Internet and
electronic commerce companies to increase their spending on Internet
advertising. The Direct Marketing Association estimates that advertisers and
direct marketers spent approximately $284 billion in 1998 on all forms of media
in the United States, up from $264 billion in 1997. Growth in Internet
advertising and direct marketing during this period, though significantly
smaller in absolute dollars, outpaced the growth of traditional advertising and
direct marketing. Jupiter Communications, another online research firm,
estimates that spending on Internet advertising will grow from $1.9 billion in
1998 to $7.7 billion in 2002, while the DMA estimates that spending on Internet
direct marketing will grow from $603 million in 1998 to $5.3 billion in 2003.

    ADVANTAGES OF INTERNET ADVERTISING AND DIRECT MARKETING
 
        The Internet offers significant advantages over traditional media as a
medium for advertising and direct marketing. We believe that the advantages
described below will lead advertisers to continue to increase spending on
Internet advertising and direct marketing.
 
        ABILITY TO REACH LARGE OR TARGETED AUDIENCES.  As a medium with no
geographic boundaries, the Internet enables advertisers to reach large audiences
in the U.S. and internationally. The Internet also affords advertisers the
opportunity to target ads to specific geographic regions, to specific interest
groups by targeting multiple Web sites with specific characteristics, and to
consumers with specific demographic profiles.
 
        INTERACTIVITY.  Unlike the broadcast model of traditional media, the
Internet is a truly interactive mass medium. Advertisers can receive immediate
feedback on the effectiveness of their ad campaigns and can complete sales
online. Advertisers can control the number of times a user sees an ad, rotate
ads in sequence for that user and build highly accurate user profiles through
transaction information, registration procedures and anonymous matching
techniques.
 
        ABILITY TO TRACK, MONITOR AND MEASURE ADVERTISING EFFECTIVENESS.  The
Internet allows advertisers to track, monitor and measure the effectiveness of
their ad campaigns, and provides the flexibility to control those campaigns
while the campaign is being delivered. Advertisers can measure the number of
times a user views a particular ad, how often the user responds or clicks
through to that ad and ultimately makes a purchase or other transaction, and
various characteristics of the user. Based on this data, advertisers can modify
ad messages and placement quickly and efficiently to maximize ad campaign
effectiveness, resulting in higher response rates. For this reason, Internet
advertising provides advertisers the potential to achieve returns on their
investments that are higher than returns currently achievable through
traditional media.
 
        GREATER FLEXIBILITY AND REDUCED COSTS.  Internet ad campaigns typically
are less time-consuming, less expensive and easier to produce than advertising
in traditional media. This allows Internet advertisers to cost-effectively
launch ad campaigns on short notice in response to specific needs or events. In
addition, once an ad campaign is launched, advertisers can easily and
inexpensively change its content, scope and frequency of delivery in response to
feedback in order to ensure that an effective message is delivered to consumers.
 
    CHALLENGES OF MANAGING AND DELIVERING EFFECTIVE INTERNET ADVERTISING
 
        The dynamic nature and rapid growth of the Internet are steadily
increasing the challenges and infrastructure requirements of delivering
effective advertising.
 
        DISAGGREGATED NATURE OF THE INTERNET.  The large number of Web sites and
the dispersed nature of the Internet audience make it difficult for advertisers
and ad agencies to identify and target specific customer segments with specific
ad campaigns. Advertisers and ad agencies often need to book ad campaigns across
hundreds of Web sites to obtain the necessary reach, number of ad impressions
and target audience. This complex and labor-intensive process includes
identifying Web sites with specific characteristics, understanding their
technical capabilities and contractual terms, identifying their available
inventory of desired page views, preparing their Web pages to accept the proper
ads, reserving and delivering ads, and tracking results. In addition, Web sites
operating an ad server independently from a network of other Web sites typically
find that they do not generate enough data from their own users to build an
effective database of Web users and their response patterns that would enable
sophisticated ad targeting.
 
        COMPLEX, RAPIDLY CHANGING TECHNOLOGY.  Delivering and tracking hundreds
of ad campaigns, with response times measured in milliseconds, to millions of
Internet users who click through to thousands of Web sites requires complex
networking, computing, applications and database technologies. In addition, as
browser vendors upgrade their software, advertisers pursue richer forms of
Internet advertising
 
                                       28
<PAGE>
incorporating sound, motion and other advanced features. As other interdependent
technologies evolve, a delivery system must be updated continually to
accommodate the rapid pace of technological change.
 
        SIGNIFICANT OPERATING COSTS AND REQUIREMENTS.  Developing, building,
operating and maintaining an ad management and delivery system is costly and
time-consuming. It requires one or more large, complex data centers with
multiple network connections and back-up capabilities. Further, to maintain
reliable performance 24 hours a day, seven days a week, these systems must be
maintained around the clock by highly-specialized operations personnel. For most
advertisers, ad agencies, Web sites and ad rep firms, these operating burdens
create a substantial diversion of investment from their core competencies.
 
        RAPID GROWTH OF WEB SITES.  Successful Web sites are experiencing rapid
growth in the number of pages and ads they deliver, with larger portal Web sites
delivering hundreds of millions of ads per day. Increasing ad management and
delivery capabilities at these Web sites requires significant investment in
technology operations infrastructure. The failure to develop a scalable solution
can limit revenue growth for these Web sites.
 
        TRUSTED REPORTING AND RESULTS.  Unlike traditional broadcast media,
Internet ads are delivered to individuals one ad at a time. For this reason,
Internet advertising campaigns are typically measured and billed by the exact
number of ad impressions delivered and, in many cases, the exact number of
click-throughs or transactions that result. Advertisers, ad agencies and other
parties prefer third-party verification of ad delivery results to use as a basis
for determining ad campaign costs and effectiveness.
 
        PRIVACY.  The use of more precise targeting capabilities by Internet
advertisers will increase the challenges of preserving user privacy. Technology
advancements, strategic partnerships and evolving business practices will be
required to balance privacy concerns with the demand for more precise targeting
capabilities.
 
    NEED FOR A CENTRALIZED, OUTSOURCED INTERNET ADVERTISING AND DIRECT MARKETING
     SOLUTION
 
        The rapid growth of the Internet as an advertising medium has made the
management and delivery of effective advertising and direct marketing extremely
important for advertisers, ad agencies, Web sites and ad rep firms. Because of
the significant technical, operational and resource challenges of ad management
and delivery, and the need to aggregate both users and data, we believe there is
a need for an outsourced, centralized Internet advertising and direct marketing
technology infrastructure provider that delivers the unique advantages of
Internet advertising while allowing advertisers, ad agencies, Web sites and ad
firms to focus on their core competencies. This infrastructure must provide high
performance and advanced functionality and be highly reliable and readily
scalable.
 
THE ADFORCE SOLUTION
 
        We provide the technology infrastructure and services that we believe
advertisers, ad agencies, Web sites and ad rep firms need to exploit the
advantages of Internet advertising and direct marketing. Our turnkey solutions
for advertisers, ad agencies, Web sites and ad rep firms offer sophisticated ad
campaign design, inventory management, targeting, delivery, tracking, measuring
and reporting capabilities built on our technology platform. Our outsourced
services and infrastructure allow our customers to focus on their core
competencies, while leveraging our systems for quick time-to-market, low entry
and maintenance costs, reliability and scalability. During 1998, we delivered
13.6 billion ads with increasing quarterly volumes of 0.9 billion, 1.6 billion,
3.2 billion and 7.9 billion. We delivered 13.2 billion ads in the first quarter
of 1999. To date, we have increased our 30-day ad impression rate to over 5.6
billion, with per day volumes of up to 210 million. Our key Web site customers
include GeoCities and Netscape, our key ad rep firm customers include 24/7 Media
and Adsmart, and our key ad agency customers include ModemMedia.PoppeTyson.
According to Media Metrix, an Internet research firm, in December 1998 AdForce
served ads to approximately 58% of U.S. Internet users.

    BENEFITS FOR ADVERTISERS AND AD AGENCIES
 
        - AdForce for Advertisers enables advertisers and ad agencies to
          schedule, target, manage and deliver ad campaigns efficiently across
          the entire Internet. Advertisers and ad agencies are able to track and
          monitor ad campaign results using our data reporting and analysis
          capabilities. Our measuring of ads delivered, which results in
          advertising billings, is audited by a third party to ensure that
          advertisers and ad agencies can have confidence in our results.
 
        - The user interface of AdForce for Advertisers, which is installed on
          our customers' personal computers, permits communications with our
          systems over the Internet and assists advertisers and ad agencies in
          the media planning process. Through this interface, advertisers and ad
          agencies can build a schedule for their campaigns by checking and
          reserving Web site inventories, and then specifying the content,
          targeting criteria and type of media, and the times at which and
          frequency with which their ads should appear. Through this interface,
          advertisers and ad agencies also can monitor ongoing campaigns, and
          adjust priorities or change ads to maximize the value of each ad
          delivered.
 
        - We store detailed information regarding every ad delivery in a manner
          that allows broad and flexible reporting. In addition to
          click-throughs, we track the activity of prospects who act on an ad by
          making a purchase or completing a survey or registration form. This
          information enables advertisers to track and measure the effectiveness
          of a campaign and maximize its value. We offer numerous reports
          covering various facets of an ad campaign with the ability to
          consolidate data across multiple Web sites.
 
        - Our services enable advertisers and ad agencies to utilize our large
          and growing database to target ad campaigns using a wide variety of
          criteria, increasing the value of their ad spending. In addition, our
          strategic relationship with Experian will permit targeting through the
          use of detailed consumer demographic data. We believe our targeting
          capabilities allow advertisers and agencies to deliver ads that are
          more relevant, less repetitious and more likely to match a particular
          user's interests. These capabilities allow ad agencies to
          differentiate themselves from their competitors, provide additional
          services to their clients and create additional revenue opportunities.
 
        - By relying on our outsourced solution and our technology
          infrastructure, advertisers and ad agencies can focus on their core
          competencies such as media planning, contract creation and direct
          marketing.
 
    BENEFITS TO WEB SITES AND AD REP FIRMS
 
        - AdForce for Publishers provides the infrastructure that Web sites need
          to maximize sales of advertising space, increase the value of their
          page views, and differentiate themselves from their competition.
          AdForce for Publishers also allows entities that operate multiple Web
          sites and ad rep firms to aggregate multiple sites and pages within
          sites into a single network. The network can then be subdivided based
          on content to create special interest groups such as sports or finance
          to maximize the value of a Web site's inventory.
 
        - Our outsourced solution provides Web sites and ad rep firms the
          advanced technology required for the complex processes of managing and
          delivering Internet advertising. In addition, our outsourced solution
          allows Web sites and ad rep firms to avoid the significant hardware,
          software and personnel costs associated with site-specific software
          services and to benefit from the scalability of our technology
          infrastructure.
 
        - Our inventory management system provides detailed reporting on current
          and estimated future ad inventory. The system ensures that ad
          campaigns are delivered evenly, smoothing the potential effects of
          unexpected traffic increases. In addition, the system monitors each
          active ad campaign, adjusting for differences in Web site traffic, to
          ensure that ads are delivered as scheduled to achieve maximum yield
          from a Web site's ad inventory. Because
 
                                       30
<PAGE>
          we enable Web sites and ad rep firms to track, monitor and measure ad
          inventory consistently, our customers can sell more premium ad space.
 
        - Our advanced targeting and reporting capabilities enable Web sites and
          ad rep firms to maximize their advertising revenues by delivering to
          their advertisers more valuable ad impressions that are more likely to
          result in a click-through or other action.
 
        - AdForce for Publishers allows ad rep firms to aggregate a number of
          Web sites to measure and manage available inventory. In addition, our
          services allow ad rep firms to schedule multiple campaigns across
          multiple sites as simply as scheduling a single site.
 
STRATEGY
 
        AdForce's objective is to be the primary technology and service
infrastructure for advertising and direct marketing on the Internet. Our
strategy consists of the following key elements:
 
        ENHANCE AND EXPAND OUR CORE TECHNOLOGY.  Our technology infrastructure
has enabled us to become a leading provider of centralized, outsourced
advertising and direct marketing services on the Internet. The ability of our
technology infrastructure to scale as Internet advertising has grown has been a
competitive advantage. In addition, by steadily increasing our ad volumes in
1998 and in the first quarter of 1999, we have been able to reduce the cost of
ad management and delivery. We intend to continue to invest heavily in research
and development activities to enhance the performance and functionality of our
core technology. In addition, we intend to continue to invest in enhancing the
reliability, scalability, performance and cost efficiency of our data center
infrastructure. We opened an additional data center in April 1999 that
significantly increases our ad delivery capacity. Our core technology has been
designed to facilitate developing new features and functionality. During the
remainder of 1999, we also plan to continue to develop new services and
capabilities for our customers.
 
        LEVERAGE AND EXPAND CUSTOMER BASE.  We seek to maintain, develop and
enhance existing and new revenue streams from our current customer base of ad
agencies, Web sites and ad rep firms, as well as revenue streams from new
customers. Our current customers, including 24/7 Media, Adsmart, GeoCities and
Netscape, substantially increased their Internet traffic during 1998, and we
expect our revenue from these customers will increase to the extent their Web
traffic continues to grow by continuing to provide them ad management and
delivery services. In addition to our recurring ad management and delivery
services, we anticipate developing additional sources of revenue by offering
advanced reporting, targeting and data analysis and by delivering ads featuring
audio, video and animation. We intend to attract and retain new customers by
promoting AdForce as the leading provider of outsourced advertising and direct
marketing services on the Internet, increasing our sales and marketing
activities and developing new services and leading technologies. To facilitate
this, we intend to continue promoting our services through online and
traditional advertising, an extensive public relations campaign, strategic
alliances and other promotional activities. As our network of customers grows,
we believe that our position as a primary provider of technology infrastructure
for ad management and delivery will be reinforced.
 
        MAINTAIN NEUTRALITY.  Our customers rely on us to provide accurate,
unbiased services and information. To fill this role as a trusted intermediary,
we believe it is essential that we not compete with our customers and avoid any
media bias. We provide the technology infrastructure to maximize the ad sales of
Web sites and ad rep firms. For this reason, we have avoided selling advertising
and putting ourselves in competition with our customers. In addition, we provide
the tools and infrastructure advertisers use to efficiently schedule and
effectively deliver complex campaigns on the Internet and to learn more about
their prospects and customers. We also avoid media buying or campaign or
creative development that would place us in competition with our existing and
potential customers. Instead, we are committed to continuing to develop the
AdForce brand to be synonymous with reliability, technical competence,
comprehensiveness and neutrality.
 
        LEVERAGE DATABASE MARKETING CAPABILITIES.  Our proprietary technology
infrastructure, substantial ad impression volumes and customer relationships
allow us to aggregate significant data regarding specific prospect and customer
behavior. This data is critical to developing a database of user profiles that
ad
 
                                       31
<PAGE>
agencies and advertisers can use to target their ad campaigns. We intend to use
this data to provide additional database marketing services to our customers so
that advertisers are able to reach targeted audiences more effectively and Web
sites are able to provide a more valuable inventory. Leveraging our strategic
relationship with Experian, we intend to provide advanced targeting and database
marketing services to our customers based on demographic and lifestyle profiles
within the next 12 months. This demographic targeting will allow advertisers and
direct marketers to engage in relationship marketing by permitting them to
identify their audiences very specifically. In order to maintain a clear focus
on user privacy, we will substitute an encrypted code for all personally
identifiable information.
 
        TARGET ADDITIONAL ADVERTISING MEDIA.  As other forms of media such as
interactive television and addressable cable boxes converge with the Internet,
we may be able to build on our knowledge and technology in interactive
advertising solutions to penetrate these media. In addition, we believe much of
our industry expertise and developed technology may be transferable to more
traditional advertising media, such as newspaper, television, radio and cable,
that may benefit from centralized, outsourced ad management solutions.
 
SERVICES
 
        We provide centralized, outsourced ad management and delivery services
that address the requirements of buyers and sellers of Internet advertising and
direct marketing. The buyers, primarily ad agencies, are served by AdForce for
Advertisers. The sellers, primarily Web sites and ad rep firms, are served by
AdForce for Publishers. We provide the following functions for our customers:
 
<TABLE>
<CAPTION>
<S>             <C>
                MEDIA PLANNING. Reflecting the media planner's workflow, AdForce for Advertisers organizes the
    [LOGO]      steps in planning and executing Internet advertising. Media planners can utilize in-house
                databases or commercial third-party research to select Web sites and build a media plan.
 
                CAMPAIGN SCHEDULING. Advertisers, ad agencies, Web sites and ad rep firms can use a Java client
    [LOGO]      application to create and schedule ad campaigns over the Internet. Our user interface helps users
                build a campaign, allowing them to specify the schedule, content units, frequency and targeting
                criteria, and then submit the ad for delivery. AdForce for Advertisers organizes campaigns to
                reflect the typical workflow of an ad agency and transmits traffic instructions to many Web sites.
                AdForce for Publishers allows Web sites and ad rep firms to view and manage all of the campaigns
                running throughout their Web sites.
 
                INVENTORY MANAGEMENT. Our automated inventory management system gives Web sites and ad rep firms
    [LOGO]      detailed information about current and future inventory, allowing them to sell available media
                space more precisely. When an ad campaign is booked, the system uses historical data to forecast
                available inventory for specified targets throughout the schedule and establishes the delivery
                frequency for each group of ads. Automatically checking each ad campaign in progress, the system
                regularly adjusts for variations in site traffic and updates available inventory while factoring
                in other ad campaigns. Our system ensures that all ad campaigns are delivered on schedule, so Web
                sites get maximum value for their inventory.
 
                TARGETING. Serving ads from a central data center, we can employ more comprehensive targeting
    [LOGO]      databases than local ad servers. This allows us to offer more targeting options and far greater
                targeting accuracy. Our customers can target campaigns using a range of criteria, including
                domain/industry code, content area, keyword, geography, schedule and site-provided data. Our
                advanced targeting capabilities enable Web sites to deliver valuable ad impressions for
                advertisers, reaching the people who are most likely to respond to the ad. Web site visitors are
                shown ads that are more relevant, less repetitious and more likely to match their interests.

                AD DELIVERY. Our ad delivery system delivers ads quickly, consistently, on schedule and on target.
    [LOGO]      Because we provide the technology infrastructure, our customers have no hardware, software,
                networks or backup systems to purchase or maintain. Our scalable architecture handles millions of
                decisions per second in order to deliver targeted ads. We have begun to deliver ads featuring
                audio, video and animation to create a more compelling user experience. Our infrastructure offers
                our customers built-in redundancy, the security of operating 24 hours a day, 7 days a week, and
                the capacity to handle both traffic growth and fluctuations.
<S>             <C>
 
                TRANSACTIONS. Our transactions feature records user activities such as click-throughs, requesting
    [LOGO]      information, registering for a service or purchasing a product. The resulting data are made
                available through reports that help Web sites demonstrate the effectiveness of campaigns on their
                Web site and record their share of transactions generated by traffic on their Web site. The
                resulting data also help advertisers and ad agencies interpret results and manage the
                effectiveness of their campaigns.
 
                REPORTING. We use detailed information accumulated from every ad delivered and consolidated across
    [LOGO]      multiple Web sites to provide our customers with dozens of accurate, timely reports. We ensure
                that ad impressions are counted accurately, whether they are delivered from our data center, the
                user's browser cache or a proxy server. Our reporting features provide Web sites and advertisers
                with reports containing information they need in a readily usable format or in Microsoft Excel.
                Advertisers and ad agencies can optimize ad campaigns for best results, and media planners can
                adjust priorities, targeting criteria and ad rotation, or swap in new ads, to maximize the value
                of campaigns in progress.
 
                AUDITING AND ACCOUNTING. We provide audited statements that detail the number of ads delivered,
    [LOGO]      click-throughs and transactions for auditing and accounting purposes. ABC Interactive, a leading
                Internet auditing service, provides a monthly audit of ads delivered and click-throughs that
                enables us to provide a statement to each customer, ensuring greater accuracy and saving the
                customer time. Our reports help automate and streamline billing operations by reducing the need
                for manual data processing. All information required to generate invoices is available in a
                readily usable format, exportable to Microsoft Excel and accounting software using a simple data
                transfer.
 
                ANALYSIS. Advertisers, ad agencies, Web sites and ad rep firms can use the information stored in
    [LOGO]      our data center to conduct post-campaign analysis of results, explore trends and examine
                alternative scenarios. By integrating user profile information such as Voyager Profiles from
                Millward Brown Interactive, a leading market research firm, we allow advertisers and ad agencies
                to characterize users who viewed and responded to their ad campaigns and to improve future media
                plans and their return on advertising spending. Web sites and ad rep firms can conduct analyses
                that help them to increase their revenues from their Web traffic.
</TABLE>
 
PLANNED SERVICE ENHANCEMENTS
 
        The primary service enhancements that we plan to implement in the next
12 months are:
 
        ADFORCE TRACKING.  We intend to continue to enhance user tracking
capabilities. While maintaining the anonymity and privacy of users, advertisers
will be able to track and record user activity related to ad campaigns. Using
this information, advertisers will be able to compare customer acquisition costs
using different ads on different sites and to track information such as the
value and frequency of purchases.
 
        DEMOGRAPHIC TARGETING.  We have been developing demographic targeting
capabilities and expect to make these capabilities available to advertisers, ad
agencies, Web sites and ad rep firms. Our targeting services will serve
dynamically targeted ads to users based on their demographic and lifestyle
profiles. User demographics will be identified by linking user cookies to known
demographic information with the
 
                                       33
<PAGE>
user's permission. As part of our demographic targeting strategy, we will
maintain user privacy by substituting all personally identifiable information
with an encrypted code allowing us to match an Internet user anonymously to
existing demographic data. Demographic targeting will increase the value of
Internet marketing and allow marketers to reach their desired prospects more
readily, generating increased revenue for our customers and for us.
 
        BANNER CO-OP SERVICE.  Small Web sites and individual home page
publishers often trade ad impressions on their pages in return for promotional
advertising on other sites within an ad network or across the Internet. Home
page publishers typically have fewer of their ads served on the network than the
number of ads they serve on their home page, allowing the network owner to sell
the remaining inventory to earn revenue. We are developing a banner co-op
service that will enable ad networks and larger sites to provide home page
publishers the ability to serve ads on their home pages in exchange for
advertising space in the network or larger site. The banner co-op will leverage
our existing technology and infrastructure to provide a system capable of
handling over a million individual home page publishers and their ad campaigns.
 
TECHNOLOGY AND DATA CENTER OPERATIONS
 
        Our ad management and delivery infrastructure employs advanced
technology and robust data centers to deliver ads 24 hours a day, 7 days a week,
for leading ad agencies, Web sites and ad rep firms.
 
    THE ADFORCE AD MANAGEMENT AND DELIVERY SYSTEM
 
        Our proprietary ad management and delivery system is divided into five
subsystems: ad management, campaign deployment, ad delivery, data analysis and
reporting. In building these subsystems, we have developed a significant amount
of proprietary software while also utilizing industry-standard hardware and
software and leading third-party technology wherever possible.
 
        AD MANAGEMENT SUBSYSTEM.  Our ad management subsystem consists of our
user application software, our inventory management system and an administrative
database. The user application software is loaded onto the customer's personal
computer and is used to communicate with our system over the Internet to design,
input, change and monitor ad campaigns and to request and receive reports.
Customers also use the user application software to validate their desired ad
campaigns against our inventory management system, a software engine that uses
proprietary algorithms to forecast available ad inventory on a given Web site or
in an AdForce-supported network, and to create daily ad campaign schedules.
Customer instructions delivered via the user application software are then
recorded in our administrative database for deployment by the campaign
deployment subsystem.
 
        CAMPAIGN DEPLOYMENT SUBSYSTEM.  Our campaign deployment subsystem
consists of a set of processes to transmit ad campaign schedules and ads from
the administrative database to the targeting database in the ad delivery
subsystem. These processes are run nightly and periodically during each day to
update schedule information and place new ad campaigns into production. Because
we are able to run these processes many times each day, customers can insert new
ad campaigns and change existing ad campaigns within an hour of our notifying
them.
 
        AD DELIVERY SUBSYSTEM.  The ad delivery subsystem consists of ad
delivery servers, ad selector servers and the targeting database. The ad
delivery servers handle ad requests coming in from the Internet, log those
requests into the data analysis subsystem for reporting purposes, and ask the ad
selector servers which ad should be served to the requesting user. The ad
selector servers choose the ads to be delivered to the particular user using a
patent-pending object-framework technology and by accessing information in the
targeting database. The ad selector servers provide that information to the ad
delivery servers, and the right ad is then served to the user.
 
        DATA ANALYSIS SUBSYSTEM.  The data analysis subsystem consists of
database and other applications for processing and storing transaction data
logged from the ad delivery servers. This information is then used by the
reporting subsystem and by our inventory management system. These data
repositories are also used for data mining and transaction correlation. Although
our database does not allow
 
                                       34
<PAGE>
specific individuals to be individually identified, we have built and will
continue building consumer profiles using information compiled in these data
repositories to use in targeting ad campaigns.
 
        REPORTING SUBSYSTEM.  The reporting subsystem also has database and
processing applications that allow us to provide industry standard and custom
reports to our customers using data from the data analysis subsystem. Customers
access the reporting subsystem by logging requests with the administrative
database. We then make reports available to the customer through the user
application software or by e-mail.
 
    DATA CENTER OPERATIONS
 
        We deliver our services primarily from a central data center located at
our product development, operations and customer service and support facility in
Costa Mesa, California. This data center houses an extensive array of servers,
multiple databases, multiple terabytes of hard disk storage and routing
equipment connecting AdForce to the Internet using several fiber optic
providers. In April 1999, we moved our headquarters to and began operating our
second data center in a new facility in Cupertino, California.
 
        We manage our system closely to ensure that we maintain excellent
performance and consistent ad delivery. Our system is self-monitored by
automated tools that measure system performance, including central processing
unit usage levels, disk usage, network and bandwidth usage, report processing
times and the response time of the system to ad requests. We also have
operations staff monitoring the system 24 hours per day, 7 days per week.
 
        In building and maintaining our system, we have focused on reliability,
scalability, performance and operating cost. For reliability, we maintain
running standby servers for components within each subsystem so that a given
server can fail and the system itself will continue to function without
interruption. We use caching in the ad delivery subsystem to ensure ads will
continue to be served to our customers based on last available information even
if the back-end subsystems fail entirely. We have the backup power and
additional air conditioning needed for reliable data center operations, and use
multiple bandwidth network providers so that we have redundant capacity. We also
protect our data by using an off-site data backup service.
 
        We aggressively increased the capacity of our system throughout 1998 and
in the first quarter of 1999 by adding additional servers and other equipment
within subsystems as needed, and by improving the performance of the subsystems
themselves. We are also continuing our development efforts to improve the
performance of components within each subsystem with a view to increasing
capacity and improving response times while reducing overall ad delivery costs.

        We believe our continued success depends on establishing a broad
customer base within each of the primary categories of advertisers, ad agencies,
Web sites and ad rep firms. Our key customers include:

        We typically are the primary or sole ad management and delivery service
provider for our Web site customers. For example, we deliver through our system
all paid advertisements for GeoCities and the majority of paid advertisements
for Netscape. In addition to our direct Web site customers, we deliver ads on
hundreds of Web sites that our ad rep firm customers represent, including such
sites as AT&T, Reuters-Yahoo, Blizzard Entertainment and Earthlink, which are
customers of 24/7 Media, and Raging Bull, Free Real Time, Net Zero, College Club
USA, The Learning Channel, UBID, 123 Greetings and SecureTax, which are
customers of Adsmart. We also reach a wide variety of additional Web sites on ad
campaigns we manage and deliver for our ad agency customers.
 
        During 1997, Petry Interactive and Katz Millenium, which are now part of
24/7 Media, accounted for 79% and 13% of net revenue. During 1998, 24/7 Media,
GeoCities and FortuneCity accounted for 40%, 16% and 11% of net revenue. During
the first quarter of 1999, 24/7 Media, Adsmart, GeoCities and Netscape accounted
for 23%, 21%, 20% and 12% of net revenue. Our business and quarterly and annual
results of operations would be materially and adversely affected by the loss of
any of these customers or any significant reduction in net revenue generated
from these customers. 24/7 Media has stated that it is currently developing a
next generation ad delivery technology that is intended to serve as its sole ad
delivery solution. It has also stated that, unless and until the development of
and transition to its own ad delivery technology is complete, it will be
primarily dependent on us to deliver ads to its networks and Web sites.
 
SALES AND MARKETING
 
        Our primary sales strategy is to sell directly to leading Web sites,
large ad agencies and ad rep firms. We sell our services in the United States
through a 20-person sales and marketing organization. These employees are
located in northern and southern California, New York and northern Virginia. In
addition, we utilize the sales organizations of our ad rep firm customers to
provide our services to the Web sites they represent.
 
        We will continue to focus our sales and marketing efforts on
establishing service relationships with large, high volume users of Internet
advertising such as 24/7 Media, Adsmart, GeoCities and Netscape. In addition, we
are increasingly targeting sales to ad agencies and intend to begin marketing to
advertisers within the next 12 months. We rely on our sales and marketing
organization, our senior management and our customer service personnel to
promote and sustain these relationships.
 
        We use a variety of marketing programs to generate demand for our
products, build market awareness, develop customer leads and establish business
relationships. Our marketing activities include preparing market research and
collateral materials, determining market requirements, managing press coverage
and other public relations activities, identifying potential customers,
participating in trade events, seminars and conferences, and establishing and
maintaining close relationships with recognized industry analysts.
 
CUSTOMER SERVICE AND SUPPORT
 
        We believe that a high level of customer service and support is critical
to the successful marketing and sale of our services. We have a comprehensive
professional organization that provides account management, technical support,
training and ongoing client services for our customers. Our customer service
personnel are available 24 hours a day, 7 days a week, to assist customers as
needed, and are currently located in California and New York. We plan to
establish additional service and support sites as needed.
 
COMPETITION
 
        The market for Internet ad management and delivery services is extremely
competitive, and we expect this competition to increase in the future. We may be
unable to compete successfully, and competitive pressures may materially and
adversely affect our business and quarterly and annual results of operations.
Our ability to compete successfully in this market depends on many factors
within and beyond our control. Please see "Risk Factors--We May Not Compete
Successfully in the Market for Internet Ad Management and Delivery Services,
Which Would Adversely Affect Our Ability to Retain Our Existing
 
                                       36
<PAGE>
Customers and to Attract New Customers" for a list of these factors. We
currently compete with providers of outsourced ad servers and related services,
including DoubleClick and MatchLogic, as well as providers of ad server software
and equipment services, such as NetGravity. Our principal competitor is
DoubleClick, which delivered over 8.0 billion ads in March 1999 as compared to
the 5.6 billion ads that we delivered in March 1999. Many of our current
competitors, including DoubleClick, have substantially greater capital
resources, more name recognition, more developed sales and marketing strategies,
and management teams that have a longer history of working together than we do.
 
        Another principal source of competition is Web sites that use
internally-developed Internet advertising and direct marketing services. These
Web sites include America Online, one of our principal stockholders, and Yahoo!.
America Online has acquired Netscape, one of our major customers, and Yahoo! has
entered into an agreement to acquire GeoCities, another of our major customers.
Following these acquisitions, either Netscape or GeoCities, or both, might
transition their systems to the proprietary systems of their acquirors, which
would materially and adversely affect our business and quarterly and annual
results of operations. In addition, 24/7 Media, another of our major customers,
acquired its own ad management and delivery technology in 1998, and currently
uses this technology to serve a portion of its advertising needs. 24/7 Media has
stated that it is currently developing a next generation ad delivery technology
that is intended to serve as its sole ad delivery solution. It has also stated
that, unless and until the development of and transition to its own ad delivery
technology is complete, it will be primarily dependent on us to deliver ads to
its networks and Web sites. If 24/7 Media were to cease doing business with us
or enter into competition with us, it would materially and adversely affect our
business and quarterly and annual results of operations. Finally, a fourth major
customer, 2CAN Media, was recently acquired by Adsmart, a subsidiary of CMG
Investments. CMG Investments also owns Engage, which recently merged with
Accipiter, a supplier of ad server software and equipment services. If Adsmart
were to transition its business from us to Accipiter, it would materially and
adversely affect our business and quarterly and annual results of operations.
 
        We may also encounter a number of potential new competitors that have
longer operating histories, greater name recognition, larger customer bases and
significantly greater financial, technical and marketing resources than we do.
These qualities may allow them to respond more quickly than we can to new or
emerging technologies and changes in customer requirements. It may also allow
them to devote greater resources than we can to the development, promotion and
sale of their products and services. These competitors might also engage in more
extensive research and development, undertake more far-reaching marketing
campaigns, adopt more aggressive pricing policies and make more attractive
offers to existing and potential employees, strategic partners, advertisers and
Web sites. If these companies were to enter the market, we might not be able to
compete against them effectively.
 
INTELLECTUAL PROPERTY
 
        Our success and ability to compete are substantially dependent on our
internally developed technologies and trademarks, which we protect through a
combination of patent, copyright, trade secret and trademark laws. If our
proprietary rights are infringed by a third party, the value of our services to
our customers would be diminished and additional competition might result from
the third party's use of those rights, which would materially and adversely
affect our business and quarterly and annual results of operations. We have
filed two patent applications in the United States. In addition, we have applied
to register trademarks in the United States. We cannot assure you that our
patent applications or trademark registrations will be approved. Even if they
are approved, our patents or trademarks may be successfully challenged by others
or invalidated. If our trademark registrations are not approved because third
parties own these trademarks, our use of these trademarks would be restricted
unless we entered into arrangements with the third-party owners, which might not
be possible on reasonable terms.
 
        Our technology collects and utilizes data derived from user activity on
the Internet. Although we believe that we generally have the right to use this
information and to compile it in our database, we cannot assure you that any
trade secret, copyright or other protection will be available for this
information. We also cannot assure you that any of our proprietary rights will
be viable or of value in the future since the validity, enforceability and scope
of protection of proprietary rights in Internet-related industries are uncertain
and still evolving. We believe that factors such as the technological and
creative skills of our
 
                                       37
<PAGE>
personnel, new service offerings, brand recognition and reliable customer
service are more essential to establishing and maintaining our technology
leadership position than the legal protection of our technology. There can be no
assurance that others will not develop technologies that are similar or superior
to our technology.
 
        We generally enter into confidentiality or license agreements with our
employees, consultants and corporate partners, and control access to and
distribution of our technologies, documentation and other proprietary
information. Despite our efforts to protect our proprietary rights from
unauthorized use or disclosure, parties may attempt to disclose, obtain or use
our solutions or technologies. We cannot assure you that the steps we have taken
will prevent misappropriation of our solutions or technologies, particularly in
foreign countries where laws or law enforcement practices may not protect our
proprietary rights as fully as in the United States.
 
        We have licensed, and we may license in the future, proprietary rights
to third parties. In particular, we have licensed our proprietary software to
America Online and Euroserve Media. In addition, before our acquisition of
StarPoint, StarPoint licensed its software to GeoCities and two other parties.
While we attempt to ensure that the quality of our brand is maintained by these
business partners, they may take actions that could materially and adversely
affect the value of our proprietary rights or our reputation. We cannot assure
you that these business partners will take the same steps we have taken to
prevent misappropriation of our solutions or technologies. Please see "Related
Party Transactions" for detailed information on our license to America Online.
 
        Third parties may assert infringement claims against us or our
customers. We do not believe that our technological processes infringe the
proprietary rights of others, but we cannot assure you that third parties will
not assert claims that we violate their rights. In addition, we believe that we
have the right to use the user data we collect for our database, but we cannot
assure you that third parties will not assert claims that we violate their trade
secrets or copyrights. Although there has not been any claims of these types in
the past, any claims and resultant litigation, if they occur, could subject us
to significant liability for damages or could result in invalidation of our
rights. In addition, even if we were to prevail, litigation could be
time-consuming and expensive to defend and could result in diversion of our time
and attention, which could materially and adversely affect our business and
quarterly and annual results of operations. Any claims or litigation from third
parties might also result in limitations on our ability to use the trademarks
and other intellectual property subject to these claims or litigations unless we
entered into arrangements with the third parties responsible for the claims or
litigation, which might be unavailable on reasonable terms, if at all.
 
PRIVACY POLICY
 
        We believe that issues relating to the privacy of Internet users and the
use of personal information about these users are critically important as the
Internet and its commercial use grow. We have adopted a detailed policy
outlining the permissible uses of information about users and the extent to
which such information may be shared with others. Our customers must acknowledge
and agree to this policy when registering to use our service. We do not sell or
license to third parties any personally identifiable information about users.
However, we do use information about users to improve marketing and promotional
efforts and to analyze usage patterns. We comply with all relevant privacy
initiatives in the industry, and we are a member of the TRUSTe program, an
independent non-profit organization that audits the privacy statements of Web
sites and their adherence to those privacy statements. Moreover, we have an
independent accounting firm regularly audit these privacy and business practices
to ensure compliance with all legal and industry accepted privacy standards.
 
EMPLOYEES
 
        As of March 31, 1999, we had 109 employees, including 53 in engineering
and data center operations, 20 in sales and marketing, 20 in customer service
and support and 16 in general and administrative. Other than as described in
"Management--Employment Agreements and Severance Agreements," none of these
individuals has an employment agreement with us. We believe that we have good
relationships with our employees. We have never had a significant work stoppage,
and none of our employees is represented under a collective bargaining
agreement. We believe that our future success will
 
                                       38
<PAGE>
depend in part on our ability to attract, integrate, retain and motivate highly
qualified technical and managerial personnel and upon the continued service of
our senior management and key technical personnel. Competition for qualified
personnel in our industry and geographical locations is intense, and there can
be no assurance that we will be successful in attracting, integrating, retaining
and motivating a sufficient number of qualified personnel to conduct our
business in the future.
 
FACILITIES
 
        Our headquarters, including our principal administrative and marketing
facilities, are located in approximately 41,151 square feet of space we have
subleased in Cupertino, California, which includes a data center with a
fully-installed infrastructure. This sublease extends through April 2003. We
intend to sublet on a short-term basis approximately 40% of the office space in
our new Cupertino headquarters. Our principal data center, product development,
operations and customer service and support facilities are located in
approximately 18,362 square feet of office space in Costa Mesa, California; the
lease on this facility extends through April 2004. We believe our Cupertino and
Costa Mesa facilities will be adequate to meet our needs for at least the next
12 months. We have sales personnel in both California offices, and in a New York
City office of approximately 1,000 square feet. The lease for the New York
office expires in December 1999.
 
LEGAL PROCEEDINGS
 
        We are not currently subject to any material legal proceedings. We may
from time to time become a party to various legal proceedings arising in the
ordinary course of our business.

served as executive vice president of Frontier Communications Corporation, a
telecommunications company, and as president of Frontier GlobalCenter. From July
1996 to February 1998, Mr. Hickey served as president and chief executive
officer of GlobalCenter, Inc., a Web hosting company. In February 1998,
GlobalCenter was acquired by Frontier. From December 1994 to July 1996, Mr.
Hickey was president of Internet services at MFS Communications, a provider of
high-speed fiber-optic services. From September 1990 to November 1994, Mr.
Hickey was general manager of North American sales and field operations at
Ardis, a Motorola company. Mr. Hickey received his bachelor of science in
economics from Siena College. Mr. Hickey serves on the board of directors of
Critical Path, a public company.
 
        Our board of directors is currently comprised of five directors and has
two vacancies. We expect Messrs. Faber and Hickey to begin serving as members of
our board of directors following the offering. Directors are elected by the
stockholders at each annual meeting of stockholders and serve for one year or
 
                                       42
<PAGE>
until their successors are duly elected and qualified. However, our bylaws
provide, following the offering, that our board of directors will be divided
into three classes as nearly equal in size as possible with staggered three-year
terms. The term of office of our Class I directors will expire at the annual
meeting of stockholders to be held in 2000; the term of office of our Class II
directors will expire at the annual meeting of stockholders to be held in 2001;
and the term of office of our Class III directors will expire at the annual
meeting of the stockholders to be held in 2002. At each annual meeting of the
stockholders, beginning with the 2000 annual meeting, the successors to the
directors whose terms will then expire will be elected to serve from the time of
their election and qualification until the third annual meeting following their
election or until their successors have been duly elected and qualified, or
until their earlier resignation or removal, if any. Messrs. Weintraut and Wray
have been designated as Class I directors; Messrs. Di Benedetto and Gorenberg
have been designated as Class II directors; and Messrs. Berger, Faber and Hickey
have been designated as Class III directors. The classification of our board of
directors could have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from acquiring, control of AdForce.
 
        America Online has the right to elect one director to the board of
directors so long as America Online holds at least 728,332 shares of common
stock, appropriately adjusted for any stock split, dividend, combination or
other recapitalization. This right expires in July 2008.
 
BOARD COMMITTEES
 
        We have established an audit committee and a compensation committee. The
audit committee reviews our internal accounting procedures and consults with and
reviews the results and scope of the audit and other services provided by our
independent accountants. The compensation committee reviews and approves the
compensation and benefits for our key executive officers and establishes and
reviews general policies relating to compensation and benefits of our employees.
 
DIRECTOR COMPENSATION
 
        Our directors do not receive cash compensation for their services as
directors, but are reimbursed for all reasonable expenses incurred in connection
with their attendance at meetings of our board of directors and committee
meetings of the board of directors.
 
        In February 1999, our board of directors adopted, and in March 1999 our
stockholders approved, the 1999 Directors Stock Option Plan. We reserved a total
of 200,000 shares of common stock for issuance under the directors plan. Members
of our board of directors who are not our employees, or employees of any parent,
subsidiary or affiliate of AdForce, are eligible to participate in the directors
plan. Option grants under the directors plan are automatic and nondiscretionary,
and the exercise price of the options must equal the fair market value of our
common stock on the date of grant.
 
        We will initially grant to each eligible director who first becomes a
member of our board of directors on or after the effective date of this offering
an option to purchase 10,000 shares of common stock on the date that director
becomes a member of our board of directors. We will initially grant to each
eligible director who became a member of our board of directors before the
effective date of this offering an option to purchase 10,000 shares of common
stock immediately following the first annual meeting of our stockholders that
occurs after the effective date of this offering. After the effective date of
this offering, immediately following each annual meeting of our stockholders
that occurs, each eligible director will automatically be granted an additional
option to purchase 5,000 shares of common stock if that director has served
continuously as a member of our board of directors for at least one year since
the date of that director's initial grant under the directors plan. The options
have ten year terms. They will terminate seven months after the director ceases
to provide services to us either as a director or a consultant, 12 months if the
termination is due to death or disability. All options granted under the
directors plan will vest at a rate of 25% of the shares on the anniversary of
the date of grant and 2.08% of the shares every
 
                                       43
<PAGE>
month after that date. Options will stop vesting if a director ceases to provide
services to us either as a director or a consultant. If a merger or other
transaction in which we are not the surviving corporation occurs, all options
issued under the directors plan will accelerate and become exercisable in full.
If a director does not exercise options within seven months of the corporate
transaction, the options will expire.
 
        In April 1999, we granted an option to purchase 50,000 shares of common
stock to Mr. Faber, and granted an option to purchase 75,000 shares of common
stock to Mr. Hickey. These options have an exercise price of $8.50 per share and
have a term of ten years. These options are immediately exercisable and will
vest at a rate of 25% of the shares on the first anniversary of the vesting
start date specified in the stock option agreements and 2.08% of the shares
every month after that date.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
        Before February 26, 1999, our board of directors did not have a
compensation committee and all compensation decisions were made by the full
board of directors. Beginning on February 26, 1999, our compensation committee
has made all compensation decisions. No interlocking relationship exists between
our board of directors or compensation committee and the board of directors or
compensation committee of any other company, nor has an interlocking
relationship existed in the past.

EXECUTIVE COMPENSATION
 
        The following table shows all compensation awarded to, earned by or paid
for services rendered to AdForce in all capacities during 1998 by our chief
executive officer and our other executive officers or former executive officers
who earned at least $100,000 in 1998.

OPTION GRANTS IN LAST FISCAL YEAR
 
        The following table shows each stock option grant during 1998 to the
officers named in the summary compensation table above. None of these officers
exercised any option in 1998.
 
        All of these options were immediately exercisable and were incentive
stock options that were granted at an exercise price equal to the fair market
value of our common stock on the date of grant, as determined by our board of
directors. The exercise price may be paid in cash, in shares of our common stock
valued at fair market value on the exercise date or through a cashless exercise
procedure involving a same-day sale of the purchased shares. We may also finance
the option exercise by lending the optionee funds to pay the exercise price for
the purchased shares. These options vest over four years at the rate of 25% of
the shares subject to the option on the first anniversary of the vesting start
date specified in the stock option agreement and 2.08% every month after that
date. Unvested shares are subject to AdForce's right of repurchase upon
termination of employment. Upon specified changes in control of AdForce, vesting
will accelerate on all shares that are then unvested. Options expire ten years
from the date of grant. See "--Employee Benefit Plans" and "--Employment
Agreements and Severance Agreements" for a description of the material terms of
these options.

(2) The options are subject to AdForce's right of repurchase, which lapsed with
    respect to 25% of the shares upon Mr. Tanner's completion of 12 months of
    service from the vesting start date and an additional 2.08% every month
    after that date. As of December 31, 1998, AdForce's right of repurchase had

EMPLOYEE BENEFIT PLANS
 
        1997 STOCK PLAN.  In April 1997, our board of directors adopted the 1997
plan and in June 1997 our stockholders approved it. The board of directors
reserved 1,200,000 shares of our common stock for issuance under the 1997 plan.
It increased this number to 2,400,000 in July 1997 and 4,000,000 in December
1997. As of March 31, 1999, options to purchase 1,626,117 shares of our common
stock had been exercised, of which 52,216 shares were repurchased by AdForce,
options to purchase 1,564,161 shares of our common stock were outstanding under
the 1997 plan with a weighted average exercise price of $0.95 and 861,938 shares
of our common stock were available for future grants. Following the closing of
this offering, no additional options will be granted under the 1997 plan.
Options granted under the 1997 plan are subject to terms substantially similar
to those described below with respect to options to be granted under the 1999
plan. However, options granted under the 1997 plan become fully vested if not
assumed or substituted by the successor corporation in connection with a merger
or asset sale.
 
        STARPOINT SOFTWARE, INC. 1996 STOCK PLAN.  In connection with AdForce's
acquisition of StarPoint Software, Inc., AdForce assumed all options outstanding
under the StarPoint plan at the closing of the acquisition. These assumed
options will remain effective until exercised for AdForce's common stock or
until they terminate or expire. Options granted under the StarPoint plan are
subject to terms substantially similar to those described below with respect to
options to be granted under the 1999 plan. However, options granted under the
StarPoint plan become fully vested if not assumed or substituted by the
successor corporation in connection with a merger or asset sale. No options will
be granted in the future under the StarPoint plan. As of March 31, 1999, options
to purchase 17,116 shares of common stock had been exercised, and options to
purchase 6,598 shares of common stock were outstanding under the StarPoint plan.
 
        1999 EQUITY INCENTIVE PLAN.  In February 1999, our board of directors
adopted, and in March 1999 our stockholders approved, our 1999 plan. We reserved
2,000,000 shares for issuance under
 
                                       47
<PAGE>
the 1999 plan. Our 1999 plan will become effective on the effective date of this
offering and will serve as the successor to our 1997 plan.
 
        Options granted under the 1997 plan and the StarPoint plan before their
termination will remain outstanding according to their terms, but no further
options will be granted under the 1997 plan or the StarPoint plan after the
effective date of this offering. In some cases, shares granted or issued under
the 1997 plan or the 1999 plan may again become available for grant or issuance
under the 1999 plan. Our 1999 plan will terminate in February 2009, unless
sooner terminated in accordance with its terms. Our compensation committee
administers our 1999 plan and has the authority to construe and interpret our
1999 plan and any agreement made under it, grant awards and make all other
determinations necessary for the administration of our 1999 plan.
 
        Our 1999 plan provides for the grant of both incentive stock options
that qualify under Section 422 of the Internal Revenue Code, and nonqualified
stock options, as well as stock awards and stock bonuses. We can grant incentive
stock options only to employees. We can grant other awards to employees,
officers, directors, consultants, independent contractors and advisors. However,
consultants, independent contractors and advisors must render actual services
not in connection with the offer and sale of securities in a capital-raising
transaction. The exercise price of incentive stock options must be at least
equal to the fair market value of our common stock on the date of grant. The
exercise price of nonqualified stock options must be at least equal to 85% of
the fair market value of our common stock on the date of grant. The maximum term
of options granted under our 1999 plan is ten years. Options granted under our
1999 plan generally expire three months after the termination of the optionee's
service. However, in the case of death or disability, the options generally may
be exercised up to 12 months following the date of death or termination of
service. Options will generally terminate immediately upon termination for
cause. If AdForce dissolves or liquidates or a change in control transaction
occurs, outstanding awards may be assumed or substituted by the successor
corporation, if any. Our compensation committee has the discretion to accelerate
the vesting of any award upon the occurrence of any of these events.
 
        See "Director Compensation" for a description of our directors plan.
 
        1999 EMPLOYEE STOCK PURCHASE PLAN.  In February 1999, our board of
directors adopted, and in March 1999 our stockholders approved, our purchase
plan. We reserved a total of 300,000 shares of common stock for issuance under
our purchase plan. On each January 1, the total number of shares reserved for
issuance will be increased automatically by the number of shares purchased under
our purchase plan in the preceding calendar year. The total number of shares
issued over the term of our purchase plan may not exceed 3,000,000 shares. Our
compensation committee administers our purchase plan and has the authority to
construe and interpret it. Our purchase plan will become effective on the
effective date of this offering.
 
        Employees generally will be eligible to participate in our purchase plan
if they are employed for more than 20 hours per week and more than five months
in a calendar year. Under our purchase plan, we permit employees to acquire
shares of our common stock through payroll deductions. Employees may select a
rate of payroll deduction between 2% and 10% of their W-2 cash compensation and
are subject to maximum purchase limitations described in our purchase plan.
Participation in our purchase plan will end automatically upon termination of
employment for any reason. Each offering period under our purchase plan will be
for two years and consist of four six-month purchase periods. The first offering
period is expected to begin on the day after the effective date of this
offering. The first purchase period may be more or less than six months long.
Offering periods and purchase periods after the date of this offering will begin
on February 1 and August 1. The purchase price under our purchase plan will be
85% of the lesser of the fair market value of our common stock on the first day
of the applicable offering period or the last day of each purchase period. Our
purchase plan will terminate in February 2009, unless earlier terminated. Our
board of directors has the authority to amend, terminate or extend the term of
our purchase plan. However, stockholder approval is required to increase the
number of shares that may be
 
                                       48
<PAGE>
issued or to change the terms of eligibility. Our board of directors is also
able to make amendments to our purchase plan if the financial accounting
treatment for our purchase plan is different than the financial accounting
treatment in effect on the date that it adopted our purchase plan.
 
        401(k) PLAN.  We sponsor a defined contribution plan intended to qualify
under Section 401 of the Internal Revenue Code. All employees who are 21 years
old are eligible to participate and may enter the 401(k) plan as of the first
day of any month. Participants may make pre-tax contributions to the 401(k) plan
of up to 15% of their eligible earnings, subject to a statutorily prescribed
annual limit. We may make matching contributions on a discretionary basis to the
401(k) plan, but have not done so to date. Each participant is fully vested in
his or her contributions, any of our matching contributions, and the investment
earnings on either. Contributions by the participants or AdForce to the 401(k)
plan, and the income earned on these contributions, are generally not taxable to
the participants until withdrawn. Contributions by AdForce, if any, will
generally be deductible by AdForce when made. Participant and AdForce
contributions are held in trust as required by law. Individual participants may

EMPLOYMENT AGREEMENTS AND SEVERANCE AGREEMENTS
 
        AdForce and Mr. Berger are parties to a letter agreement dated June 27,
1997 governing his employment with AdForce. Under the agreement, AdForce agreed
to pay Mr. Berger an annual salary of $250,000 and to grant him an immediately
exercisable option under the 1997 plan to purchase 900,000 shares of AdForce's
common stock at an exercise price of $0.125 per share. Mr. Berger exercised this
option in full on June 30, 1997 and paid the purchase price of the option,
$112,500, by issuing a promissory note to AdForce that is secured by a pledge of
the common stock purchased and forgivable in four annual installments, provided
Mr. Berger remains an employee. On June 30, 1998, AdForce's repurchase right
with respect to the 900,000 shares began to lapse. One quarter of the option
shares vested on that date and the remaining option shares began to vest monthly
after that date over the next 36 months of service. The agreement provided for
full vesting if (1) AdForce merges or consolidates with or into another entity
where more than 50% of the combined voting power of the surviving corporation's
securities outstanding immediately after the transaction is owned by persons who
were not stockholders of AdForce immediately before that transaction or (2) the
sale, transfer or other disposition of all or substantially all of AdForce's
assets, each a change of control, and in either case the option is not assumed
by the successor corporation. Finally, the agreement provided that, if (1) a
change of control occurs, (2) Mr. Berger's option is assumed and (3) his
employment is involuntarily terminated or Mr. Berger resigns for good reason
within 24 months of the change of control, Mr. Berger's option will become
vested and AdForce's repurchase right will lapse with respect to an additional
number of shares equal to the number of shares that would have vested if Mr.
Berger served for an additional 12 months.
 
        In November 1998, AdForce and Mr. Berger entered into a letter agreement
regarding salary continuation and option vesting. Under the letter agreement, if
Mr. Berger's employment with AdForce is involuntarily terminated by AdForce
other than for cause or if Mr. Berger resigns for good reason, Mr. Berger will
receive salary continuation at his current rate of salary and continuation of
vesting of his options or restricted stock vesting for a period of twelve months
following termination. Under the letter agreement, cause is defined to include
failure to follow the written directions of the board of directors, dishonesty,
gross misconduct, fraud, or conviction for a felony, and good reason is defined
to include demotion, salary reduction or relocation.
 
        In April 1999, AdForce granted Mr. Berger an immediately exercisable
option to purchase 100,000 shares of AdForce's common stock at an exercise price
of $8.50 per share. AdForce's repurchase right will begin to lapse and 25% of
the shares will vest after one year of service; the balance of the shares will
vest monthly over the next 36 months of service.

and granted Mr. Rao an option to purchase 360,000 shares of common stock at an

service.
 
        AdForce and Mr. Tanner are parties to an employment agreement dated
December 9, 1998 governing his employment with AdForce. Under the agreement,
which has a term of two years, AdForce agreed to pay Mr. Tanner a base salary of
$175,000 and an incentive bonus under AdForce's incentive bonus plan. The
agreement provides for an additional one year of vesting of Mr. Tanner's
existing options (1) if AdForce merges with or is acquired by another company
and is not the surviving entity, (2) if AdForce sells all or substantially all
of its assets or stock or (3) if any other reorganization or business
combination involving AdForce results in 50% or more of AdForce's outstanding
voting stock being transferred to different holders. Finally, if AdForce
terminates Mr. Tanner's employment before the end of the term of the agreement
other than for cause, death or disability, or if Mr. Tanner terminates his
employment for good reason, Mr. Tanner will receive a severance amount equal to
his then-current base salary for 12 months following the date of termination,
plus benefits and any earned bonuses. In April 1999, AdForce granted Mr. Tanner
an immediately exercisable option to purchase 25,000 shares of AdForce's common
stock at an exercise price of $8.50 per share. AdForce's repurchase right will
begin to lapse and 25% of the shares subject to this option will vest after one

bonus, and granted Mr. Cravens an immediately exercisable option to purchase

share. AdForce's repurchase right will lapse and 25% of the shares subject to
the option will vest after one year of service; the balance of the shares will
vest monthly over the next 36 months of service. In April 1999, AdForce granted
Mr. Cravens an immediately exercisable option to purchase 25,000 shares of
AdForce's common stock at an exercise price of $8.50 per share. AdForce's
repurchase right will begin to lapse and 25% of the shares subject to this
option will vest after one year of service; the balance of the shares will vest
monthly over the next 36 months of service.
 
        AdForce and Mr. Glaves are parties to a letter agreement dated December
28, 1998, as revised on December 31, 1998, governing his employment with
AdForce. Under the agreement, AdForce agreed to pay Mr. Glaves an annual salary
of $150,000 and a maximum quarterly performance bonus of $25,000, with the first
quarter's payment guaranteed, and granted him an immediately exercisable option
to purchase 175,000 shares of AdForce's common stock at an exercise price of
$1.50 per share. AdForce's repurchase right will lapse and 12.5% of the shares
subject to the option will vest after six months of service; the balance of the
shares will vest monthly over the next 42 months of service. In April 1999,
AdForce granted Mr. Glaves an immediately exercisable option to purchase 25,000
shares of AdForce's common stock at an exercise price of $8.50 per share.

        AdForce and Mr. Jackson are parties to a letter agreement dated July 22,
1998 governing his employment with AdForce. Under the agreement, AdForce agreed
to pay Mr. Jackson an annual salary of $150,000, and granted him an immediately
exercisable option to purchase 180,000 shares of AdForce's common stock at an
exercise price of $1.50 per share. AdForce's repurchase right will lapse and 25%
of the shares subject to the option will vest after one year of service; the
balance of the shares will vest monthly over the next 36 months. The vesting of
Mr. Jackson's options will accelerate in the same manner as Mr. Berger's upon
the changes in control described on the preceding page. In April 1999, AdForce
 
                                       50
<PAGE>
increased Mr. Jackson's annual salary to $175,000 and granted him an immediately

        AdForce and Mr. Steelberg are parties to a settlement agreement and
release dated November 20, 1998 relating to the termination of Mr. Steelberg's
employment with AdForce. The agreement provided that, instead of amounts
otherwise payable to Mr. Steelberg, AdForce would pay him $225,000, that all
outstanding shares of common stock held by Mr. Steelberg on the date of the
agreement would be deemed fully vested, and that all unexercised options to
purchase common stock would terminate. However, certain agreements between the
parties remain enforceable. The agreement also provided for a mutual release of
claims.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
        Our certificate of incorporation limits the liability of our directors
to the maximum extent permitted by Delaware law. Delaware law provides that a
director of a corporation will not be personally liable for monetary damages for
breach of fiduciary duty as a director, except for liability:
 
        - for any breach of the director's duty of loyalty to the corporation or
          its stockholders;
 
        - for acts or omissions not in good faith or that involve intentional
          misconduct or a knowing violation of law;
 
        - under section 174 of the Delaware General Corporation Law regarding
          unlawful dividends and stock purchases; or
 
        - for any transaction from which the director derived an improper
          personal benefit.
 
        As permitted by Delaware law, our bylaws provide that:
 
        - we must indemnify our directors and officers to the fullest extent
          permitted by Delaware law, provided that each indemnified officer and
          director acted in good faith and in a manner that the officer or
          director reasonably believed to be in or not opposed to AdForce's best
          interests;
 
        - we may indemnify our other employees and agents to the same extent
          that we indemnify our officers and directors, unless otherwise
          required by law, our certificate of incorporation, our bylaws or any
          agreements;
 
        - we must advance expenses, as incurred, to our directors and officers
          in connection with a legal proceeding to the fullest extent permitted
          by Delaware law, subject to very limited exceptions; and
 
        - the rights conferred in our bylaws are not exclusive.
 
        In addition to the indemnification required in our certificate of
incorporation and bylaws, before the completion of this offering, we intend to
enter into indemnity agreements with each of our current directors and officers.
These agreements provide for the indemnification of our officers and directors
for all expenses and liabilities incurred in connection with any action or
proceeding brought against them by reason of the fact that they are or were
agents of AdForce. In addition, we intend to obtain directors' and officers'
insurance to cover our directors, officers and some of our employees for certain
liabilities. We believe that these indemnification provisions and agreements and
this insurance are necessary to attract and retain qualified directors and
officers.
 
        The limitation of liability and indemnification provisions in our
certificate of incorporation and bylaws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary
 
                                       51
<PAGE>
duty. They may also reduce the likelihood of derivative litigation against
directors and officers, even though an action, if successful, might benefit us
and other stockholders. Furthermore, a stockholder's investment may be adversely
affected to the extent we pay the costs of settlement and damage awards against
directors and officers as required by these indemnification provisions.
 
        At present, there is no pending litigation or proceeding involving any
of our directors, officers or employees regarding which indemnification by
AdForce is sought, nor are we aware of any threatened litigation that may result
in claims for indemnification.
 
                           RELATED PARTY TRANSACTIONS
 
        We have never been a party to, and we have no plans to be a party to,
any transaction or series of similar transactions in which the amount involved
exceeds $60,000 and in which any director, executive officer or holder of more
than 5% of our common stock had or will have an interest other than as described
under "Management" and the transactions described below. The numbers of shares
of preferred stock and the per share prices of shares of preferred stock
described below are reported on an as-if-converted to common stock basis.

shares of Series A preferred stock in exchange for the cancellation of $506,000

                                       52
<PAGE>
Hummer Winblad Venture Partners, which is the general partner of these funds. In
addition, 21st Century Internet Fund, L.P. purchased 997,438 shares of Series B

        Also in December 1996, as a condition of the purchase of Series B
preferred stock and as a condition to the repayment of indebtedness of AdForce
with the proceeds of the sale, AdForce entered into agreements with some of its
founders. Under these agreements, AdForce repurchased 7,886 shares of common
stock and 1,605,014 shares of common stock from Chad Steelberg, our former
President, and Washington Holdings, L.P., a principal stockholder, respectively.
Also, Chad Steelberg and Ryan Steelberg granted AdForce repurchase rights with
respect to shares owned by them. Finally, Washington Holders, L.P. acknowledged
transfer restrictions and granted Messrs. Gorenberg and Weintraut an irrevocable
proxy to elect to convert 402,964 shares of Series A preferred stock to common

Series A preferred stock in excess of $1.255 per share.
 
        In June 1997, as part of his employment with AdForce, AdForce loaned
Charles W. Berger, our Chief Executive Officer, $112,500 to be used by Mr.
Berger to exercise his option to purchase 900,000 shares of common stock. The
loan, which was evidenced by a promissory note, is due in June 30, 2001 and
accrues interest at the annual rate of 6.8%, compounded annually. The promissory
note is secured by the shares of common stock acquired by Mr. Berger upon
exercise of his option grant. However, Mr. Berger remains personally liable for
the payment of the promissory note, and Mr. Berger's assets, in addition to the
shares of common stock, may be applied to satisfy Mr. Berger's obligations under
the promissory note. The note and related interest are being forgiven ratably
over a period of four years of service/employment. At December 31, 1998, AdForce
forgave $42,188, and there remained $70,312 outstanding under the loan. See

<PAGE>
notes of $3,000, $17,000 and $480,000 and accrued interest. In addition, IBL
Corporation purchased 72,832 shares of Series D preferred stock for a purchase
price of $499,992.
 
        In July 1998, in consideration of the holders of our Series D preferred
stock agreeing to amendments to our then effective articles of incorporation
that, if not amended, would have triggered some anti-dilution protections
benefiting the holders of Series D preferred stock, we issued to the holders of
our Series D preferred stock warrants to purchase up to 72,860 shares of Series
D preferred stock at an exercise price of $6.865 per share. The warrants are
exercisable on or before July 14, 2003. The Convergence group of funds, the

also issued to America Online a warrant to purchase up to 1,019,662 shares of
Series E preferred stock at an exercise price of $6.865 per share. The warrant
is exercisable on or before July 14, 2003.
 
   
        We believe that the transactions described above were made on terms no
less favorable to us than could have been obtained from unaffiliated third
parties.
    
 
    COMMERCIAL AGREEMENTS
 
   
        In August 1998, AdForce entered into a services agreement with 2CAN
Media, which has been acquired by Adsmart. Two of AdForce's founders, Chad
Steelberg and Ryan Steelberg, worked for 2CAN Media, and now work for Adsmart.
Chad Steelberg and Ryan Steelberg originally developed some of our core
technologies. We believe that Chad Steelberg and Ryan Steelberg had a material
ownership interest and held executive management positions in 2CAN Media, and
may have similar interests and hold similar positions in Adsmart as well, but we
are unable to confirm our beliefs. In the services agreement, 2CAN Media agreed
to use our Internet advertising administration system as its exclusive
advertising serving technology. For our basic service, we charge Adsmart based
on the monthly volume of ads served, ranging from $0.55 per thousand ads served
if monthly volume is less than 300 million, to $0.25 per thousand ads served if
monthly volume is more than 1 billion. These prices are not lower than those
given to unaffiliated third parties with similar ad volumes. However, we have
agreed to give Adsmart most favored nation pricing protection, which could
result in lower prices to Adsmart if we give better pricing to other
organizations that are exclusively in the business of ad sales and delivering
similar volumes on similar terms as Adsmart. As of March 31, 1999, the agreement
had generated $942,000 in net revenue for AdForce. The agreement expires on
February 25, 2000.
    
 
        In connection with the July 1998 sale of Series E preferred stock to
America Online, AdForce also entered into a license agreement and a demographic
data agreement with America Online.
 
   
        LICENSE AGREEMENT.  Under the license agreement, we licensed our
technology to America Online and its affiliates to be used internally by America
Online and on sites associated with America Online. The licensed technology
includes future enhancements to our technology and is warranted to perform
according to its specifications. The license is fully paid, nonexclusive,
perpetual, worldwide and nontransferable except for some assignments and
includes source code. We can terminate the license only in the event of a
material, uncorrected breach of the license agreement or demographic data
agreement by America Online. For the duration of the license, if requested, we
will provide technical support, development services and ad serving services on
a cost or cost plus basis if America Online is not in default. We will provide
these services at cost if America Online provides us access to demographic data
under the demographic data agreement and America Online is not in breach of the
demographic data agreement. Otherwise, we can mark up the cost of our services
by 25% under most circumstances, and an
    
 
                                       54
<PAGE>
   
additional 15% under other circumstances, as specified in the license agreement.
To our knowledge, we would not agree to provide these services on these terms to
any other party. Under the license agreement, America Online will use
commercially reasonable efforts to encourage others associated with America
Online to use our technology, and we will use commercially reasonable efforts to
encourage our customers to use America Online in the sale of interactive
advertising. In either case, commission or revenue sharing obligations can
arise. To date, America Online has not used our technology on its sites and has
not requested any services from us.
    
 
   
        DEMOGRAPHIC DATA AGREEMENT.  Under the demographic data agreement,
America Online may authorize us to use demographic information about America
Online users in connection with the targeting and delivery of ads to these
users. AdForce and America Online will establish a timetable and procedures for
the implementation of access to the data subject to America Online's
determination that targeted advertising has become a generally accepted practice
on the Internet. If we receive demographic information from America Online, the
demographic information will not identify the user by name or address, and will
only be able to be used for serving targeted ads to America Online users. We
cannot use the demographic data to serve ads from advertisers or Web sites that
America Online finds objectionable, or from advertisers or Web sites on a list
provided by America Online. America Online may add names to this list at will,
but expenditures of these advertisers and revenues of these sites cannot exceed
25% of available advertising dollars on the Internet. America Online reserves
the right to limit or discontinue access to demographic data in the event of
adverse publicity, regulation, legal claims or changes to America Online
advertising and privacy policies. In the first year after we receive access to
the demographic data, we will pay America Online quarterly fees based on the
greater of $1.0 million, 10% of the consideration charged by us for targeted
advertising using America Online data, and 70% of the incremental revenue
charged by us for the targeting feature. The minimum payment for the first year
is $4.0 million; if other quarterly fees described above reach $5.0 million in
the first year, the percentages above would be reduced by one-half. In the
second year, quarterly fees to America Online would be based on the greater of
$750,000, 5% of the consideration charged by us for targeted advertising using
America Online data, and 35% of the incremental revenue charged by us for the
targeting feature. The minimum payment for the second year is the greater of
$3.0 million and one-half the total payments made by us to America Online in the
first year. In the third year, quarterly fees to America Online would be
calculated based on the same formula as the second year. The minimum payment for
the third year is the greater of $3.0 million and one-half the total payments
made by us to America Online in the second year. The demographic data agreement
will expire on the earlier of July 14, 2002 or three years after we have access
to the demographic data. America Online can elect to renew the demographic data
agreement on the same terms and conditions on a year-to-year basis with 90 days'
notice, subject to establishing mutually agreeable minimum annual fees. America
Online can elect to terminate the demographic data agreement upon payment of a
fee to us if a third party offers more favorable terms for access to the
demographic data and we do not match those terms. The demographic data agreement
cannot be assigned or transferred in connection with a change in control without
the consent of AdForce and America Online. To date, America Online has not
determined that the targeting of advertising has become a generally accepted
practice, so we have not had access to the demographic data. There is currently
no final implementation schedule or procedure for this access.
    
 
   
        AdForce entered into a license agreement in February 1999 with Netscape,
similar to the license agreement with America Online described above. Under the
terms of the license agreement, upon the merger of Netscape and America Online,
which was completed in March 1999, we licensed our technology to Netscape and
its affiliates to be used internally by Netscape and on sites associated with
Netscape. The licensed technology includes future enhancements to our technology
and is warranted to perform according to its specifications. The license is
fully paid, nonexclusive, perpetual, worldwide and nontransferable, except for
some assignments, and includes source code. For the initial term of the license
agreement, which ends November 22, 1999, the estimated charges to Netscape are
approximately $2.7 million. Netscape has prepaid this amount. Our estimated
charges per thousand ads served is $0.10
    
 
                                       55

through October 1999 and $0.08 for the first 22 days of November 1999; however,
if actual volumes are lower than forecasted, these charges will be higher. These
prices are significantly lower than we give to any other party. During the first
quarter of 1999, we generated $396,000 in net revenue from Netscape, $209,000 of
which is attributable to services provided since February 1999 when the license
agreement was signed. We can terminate the license of the technology only in the
event of a material, uncorrected breach by Netscape of the license agreement or
the demographic data agreement, if AdForce and Netscape elect to enter a
demographic data agreement. At this time, AdForce and Netscape have not entered
a demographic data agreement. We will provide technical support and development
services in connection with Netscape's use of the technology and we will provide
ad servicing services, all on a cost or cost plus basis if Netscape is not in
default. We will provide these services at cost if Netscape provides us access
to demographic data under the demographic data agreement and Netscape is not in
breach of the demographic data agreement. Otherwise, we can mark up the cost of
our services by 25% under most circumstances, and an additional 15% under other
circumstances, as specified in the license agreement. Under the license
agreement, Netscape will use commercially reasonable efforts to encourage others
associated with Netscape to use our technology. Under this arrangement,
commission or revenue sharing obligations can arise. The agreement to provide
technical support and development services runs for the duration of the license.
The license agreement is renewable for a one-year term upon written agreement of
AdForce and Netscape. To our knowledge, we would not agree to provide any of the
services under this agreement to any other party under these same terms.

                             PRINCIPAL STOCKHOLDERS
 
        The following table shows certain information with respect to beneficial
ownership of our common stock as of March 31, 1999 by (1) each stockholder known
by us to be the beneficial owner of more than 5% of our common stock; (2) each
of our directors; (3) each of our officers named in the Summary Compensation
Table above; and (4) all executive officers and directors as a group.
 
        Beneficial ownership is determined in accordance with the rules of the
SEC and represents sole or shared voting or sole or shared investment power with
respect to securities. Unless otherwise indicated below, the persons and
entities named in the following table have sole voting and sole investment power
with respect to all shares beneficially owned, subject to community property
laws where applicable. Shares of common stock subject to options or warrants
that are currently exercisable or exercisable within 60 days of March 31, 1999
are deemed to be outstanding and to be beneficially owned by the person holding
the options or warrants for the purpose of computing the percentage ownership of
that person, but are not treated as outstanding for the purpose of computing the
percentage ownership of any other person.
 
        The following table assumes that the underwriters' over-allotment option
to purchase up to 675,000 shares from AdForce is not exercised.

                          DESCRIPTION OF CAPITAL STOCK
 
        Immediately following the closing of this offering, our authorized
capital stock will consist of 100,000,000 shares of common stock, and 5,000,000
shares of preferred stock. As of March 31, 1999, assuming the conversion of all
outstanding preferred stock into common stock, there were outstanding 14,669,429
shares of common stock held of record by 167 stockholders, options to purchase
2,280,759 shares of common stock and warrants to purchase 1,294,686 shares of
common stock.
 
COMMON STOCK
 
        Subject to preferences that may apply to shares of preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to receive dividends out of assets legally available for dividends at
times and in amounts as our board of directors may from time to time determine.
Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders. Cumulative voting for the election
of directors is not authorized by our certificate of incorporation, which means
that the holders of a majority of the shares voted can elect all of the
directors then standing for election. The common stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Upon a
liquidation, dissolution or winding-up of AdForce, the assets legally available
for distribution to stockholders would be distributed ratably among the holders
of the common stock and any participating preferred stock outstanding at that
time after payment of liquidation preferences, if any, on any outstanding
preferred stock and payment of other claims of creditors. Each outstanding share
of common stock is, and all shares of common stock to be outstanding upon
completion of this offering will be upon payment for those shares, duly and
validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
        Upon the closing of this offering, each outstanding share of preferred
stock will be converted into two shares of common stock. See note 8 of the notes
to the financial statements for a description of the preferred stock currently
outstanding. Following the offering, our board of directors will be authorized,
without any further vote or action by the stockholders and subject to
limitations prescribed by Delaware law, to issue up to 5,000,000 shares of
preferred stock in one or more series, to establish from time to time the number
of shares to be included in each series, to fix the rights, preferences and
privileges of the shares of each series and any qualifications, limitations or
restrictions on those shares, and to increase or decrease the number of shares
of each series. Our board of directors may authorize the issuance of preferred
stock with voting or conversion rights that could adversely affect the voting
power or other rights of the holders of the common stock. The issuance of
preferred stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of delaying,
deferring or preventing a change in control of AdForce and might adversely
affect the market price of the common stock and the voting and other rights of
the holders of common stock. We have no current plan to issue any shares of
preferred stock.
 
REGISTRATION RIGHTS
 
        After this offering, the holders of approximately 10,532,696 shares of
common stock and warrants to acquire common stock will be entitled to rights to
register of those shares. As a result of an investors' rights agreement dated as
of July 15, 1998 between AdForce and certain of our stockholders, the
stockholders, holding an aggregate of 9,244,152 shares of our common stock
issuable upon conversion of our Series A preferred stock, Series B preferred
stock, Series C preferred stock, Series D preferred stock and Series E preferred
stock, have rights to register their shares that they may exercise at any time
after 180 days following the closing of this offering. Under the investors'
rights agreement, holders of: (1) at least 30% of the voting power of the
outstanding Series B preferred stock, (2) 30% of the voting power of the
outstanding Series C preferred stock, (3) a majority of the voting power of the
outstanding Series D
 
                                       59
<PAGE>
preferred stock or (4) a majority of the voting power of the outstanding Series
E preferred stock may demand, by written request, that we file a registration
statement under the Securities Act covering all or a portion of their preferred
stock, provided that, in the case of a registration statement on a form other
than a Form S-3, the registration statement has an aggregate proposed offering
price to the public, net of underwriters' discounts and commissions, of at least
$7,500,000 or, in the case of a registration on a Form S-3, there is a
reasonably anticipated aggregate offering price to the public of at least
$1,000,000, or $3,000,000 in the case of Series E preferred stock. These
stockholders may not demand more than three Form S-3 registrations in total or
more than two in any one year. These registration rights are subject to
AdForce's right to delay the filing of a registration statement not more than
once in a 12-month period, for not more than 90 days, after receiving the
registration demand in the case of a registration on a form other than a Form
S-3, and 60 days in the case of a registration on a Form S-3.
 
        In addition, the stockholders who are parties to the investors' rights
agreement, and holders of rights to acquire 100,176 shares of common stock, have
piggyback registration rights. If AdForce proposes to register any of its common
stock under the Securities Act, other than under the investors' demand
registration rights noted above, these stockholders may require AdForce to
include all or a portion of their stock in the registration; provided, however,
that the managing underwriter, if any, of the offering has rights to limit the
amount of stock held by those investors included in a registration to 30% of the
aggregate shares included in the offering.
 
        All registration expenses incurred in connection with the above
registrations will be borne by AdForce. Each selling stockholder will pay all
underwriting discounts and selling commissions applicable to the sale of that
stockholder's stock.
 
        Demand and piggyback registration rights under the investors' rights
agreement will terminate with respect to a stockholder when (1) that stockholder
owns less than 1% of the outstanding securities of AdForce, (2) that stockholder
is able to sell all its shares in a three-month period under Rule 144 of the
Securities Act and (3) AdForce is subject to the reporting requirements of
Section 13(a) or 15(d) of the Securities Exchange Act of 1934.
 
ANTI-TAKEOVER PROVISIONS
 
    DELAWARE LAW
 
        Upon the closing of this offering, we will be subject to the provisions
of Section 203 of the Delaware General Corporation Law regulating corporate
takeovers. Section 203 prevents some Delaware corporations, including those
whose securities are listed on the Nasdaq National Market, from engaging, under
some circumstances, in a business combination with any interested stockholder
for three years following the date that that stockholder became an interested
stockholder of AdForce. For purposes of Section 203, a business combination
includes a merger or consolidation involving AdForce and the interested
stockholders and the sale of more than 10% of our assets. In general, Section
203 defines an interested stockholder as any entity or person owning 15% or more
of our outstanding voting stock and any entity or person affiliated with or
controlled by or controlling that entity or person.
 
        A Delaware corporation may opt out of Section 203 with an express
provision in its original certificate of incorporation or an express provision
in its certificate or incorporation or bylaws resulting from a stockholders'
amendment approved by at least a majority of the outstanding voting shares. We
have not opted out of the provisions of Section 203. Section 203 could prohibit
or delay mergers or other takeover or change-in-control attempts with respect to
us and, accordingly, may discourage attempts to acquire us.
 
                                       60
<PAGE>
    CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS
 
        Our certificate of incorporation and bylaws provide for the division of
our board of directors into three classes as nearly equal in size as reasonably
possible with staggered three-year terms. Our stockholders are unable to fill
any vacancy on our board of directors. Any action required or permitted to be
taken by our stockholders at an annual meeting or a special meeting of the
stockholders may only be taken if it is properly brought before that meeting and
may not be taken by written consent. Our stockholders are limited in their
ability to remove any director or the entire board of directors without cause.
Our bylaws provide that special meetings of the stockholders may be called at
any time by the board of directors, and must be called upon the request of the
chairman of the board of directors, the chief executive officer, the president,
stockholders that are entitled to cast not less than a majority of the total
number of votes entitled to be cast by all stockholders of that special meeting,
or by a majority of the members of the board of directors. These provisions of
our certificate of incorporation and bylaws are intended to enhance the
likelihood of continuity and stability in the composition of the board of
directors and to discourage transactions that may involve an actual or
threatened change of control of AdForce. These provisions are designed to reduce
the vulnerability of AdForce to an unsolicited acquisition proposal and,
accordingly, could discourage potential acquisition proposals and could delay or
prevent a change in control of AdForce. These provisions are also intended to
discourage tactics that may be used in proxy fights but could, however, have the
effect of discouraging others from making tender offers for our shares and,
consequently, may also inhibit fluctuations in the market price of our shares
that could result from actual or rumored takeover attempts. These charges may
also have the effect of preventing changes in our management. See "Risk
Factors--Provisions in Our Charter Documents May Deter Acquisition Bids for
AdForce, Which Could Adversely Affect the Market Price of Your Shares."
 
TRANSFER AGENT AND REGISTRAR
 
        The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
        Before this offering, you could not buy or sell our common stock on a
public market. An active public market for our common stock may not develop or
be sustained after this offering. Future sales of substantial amounts of common
stock, including shares issued upon exercise of outstanding options or warrants,
in the public market after this offering could adversely affect the prevailing
market price of our common stock and could impair our ability to raise equity
capital in the future. In addition, since few shares will be available for sale
immediately after this offering due to the contractual and legal restrictions on
resale described below, sales of substantial amounts of our common stock in the
public market after the restrictions lapse could adversely affect the prevailing
market price and our ability to raise equity capital in the future.
 
        Upon completion of this offering, we will have outstanding 19,169,429
shares of common stock based on shares outstanding at March 31, 1999, assuming
no exercise of the underwriters' over-allotment option and no exercise of
outstanding options or warrants. Of this amount, 5,207,368 shares, including the
4,500,000 shares sold in this offering, will be freely tradable in the public
market without restriction or further registration under the Securities Act,
unless those shares are purchased by any of our affiliates. An affiliate of
AdForce is a person that directly, or indirectly through one or more
intermediaries, controls, or is controlled by, or is under common control with,
AdForce. Our current affiliates include the individuals and entities listed
under "Principal Stockholders" as well as our other executive officers. The
remaining 13,962,061 shares held by existing stockholders are subject to various
resale restrictions. Of these shares, 12,512,441 shares are subject to lock-up
agreements with the underwriters, under which all of our directors and officers
and most of our stockholders have agreed not to transfer or dispose of, directly
or indirectly, any shares of common stock or any securities convertible into or
exercisable or exchangeable for shares of common stock, for a period of 180 days
after the date of this prospectus. Hambrecht & Quist LLC may release the shares
subject to the lock-up agreements in whole or in part at any time with or
without notice. Hambrecht & Quist LLC has no current plans to do so. An
additional 1,449,620 shares are subject to a 180-day lockup through agreements
directly with us that we have agreed to enforce if requested by the
underwriters. Beginning 180 days after the date of this prospectus, the
13,962,061 shares subject to various resale restrictions will be eligible for
sale in the public market under Rule 144 or Rule 701, although 6,411,366 shares
will be subject to volume limitations. The remaining shares subject to various
resale restrictions will become eligible for sale, subject to volume
limitations, on October 28, 1999.
 
    RULE 144
 
        In general, under Rule 144, beginning 90 days after the date of this
prospectus, an affiliate of AdForce who has beneficially owned restricted shares
for at least one year but less than two years, would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of:
 
        - 1% of the number of shares of common stock then outstanding, equal to
          approximately 191,694 shares immediately after this offering; or
 
        - the average weekly trading volume of the common stock on the Nasdaq
          National Market during the four calendar weeks preceding the filing of
          a notice of sale with the SEC.
 
        Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us.
 
    RULE 144(K)
 
        Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner except one of our affiliates, is
entitled to
 
                                       62
<PAGE>
sell those shares without complying with the manner of sale, public information,

        The underwriting agreement provides that the obligations of the
underwriters are subject to specified conditions, including the absence of any
material adverse change in AdForce's business and the receipt of certificates,
opinions and letters from AdForce, its counsel and its independent auditors. The
underwriters are committed to purchase all of the shares of common stock offered
by us if they purchase any shares.
 
   
        The underwriters propose to offer the shares of common stock directly to
the public initially at the initial public offering price shown on the cover
page of this prospectus and to dealers selected by the underwriters at that
price less a concession not in excess of $0.60 per share. The underwriters may
allow and those dealers may reallow a concession not in excess of $0.10 per
share to other dealers. After the initial public offering of the shares, the
offering price and other selling terms may be changed by the underwriters.
    
 
        We have granted to the underwriters an option, exercisable no later than
30 days after the date of this prospectus, to purchase up to 675,000 additional
shares of common stock at the initial public offering price, less the
underwriting discounts shown on the cover page of this prospectus. To the extent
that the underwriters exercise this option, each of the underwriters will have a
firm commitment to purchase approximately the same percentage of those
additional shares which the number of shares of common stock to be purchased by
it shown in the above table bears to the total number of shares of common stock
offered by us. We will be obligated pursuant to this option to sell shares to
the underwriters to the extent the option is exercised. The underwriters may
exercise this option only to cover over-allotments made in connection with the
sale of shares of common stock offered by us.
 
        The offering of the shares is made for delivery when, as and if accepted
by the underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the offering without notice. The underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
                                       64

        We have agreed to indemnify the underwriters against specified
liabilities, including liabilities under the Securities Act, and to contribute
to payments the underwriters may be required to make in respect of those
liabilities.
 
        AdForce and its officers, directors and certain other stockholders, who
will own in the aggregate 12,512,441 shares of common stock after the offering,
have agreed that they will not, without the prior written consent of Hambrecht &
Quist LLC, offer, sell or dispose of any shares of common stock, options or
warrants to acquire shares of common stock or securities exchangeable for or
convertible into shares of common stock owned by them for a period of 180 days
following the date of this prospectus. AdForce has agreed that it will not,
without the prior written consent of Hambrecht & Quist LLC, offer, sell, grant
any option to purchase or dispose of any shares of common stock or any
securities exchangeable for or convertible into shares of common stock for a
period of 180 days following the date of this prospectus, except that AdForce
may issue, and grant options to purchase, shares of common stock under its stock
and employee stock purchase plans and under currently outstanding options. Sales
of these shares in the future could adversely affect the market price of the
common stock.
 
        Of the 4,500,000 shares of common stock to be sold in this offering, the
underwriters have reserved for sale, at the price to public shown on the cover
page of this prospectus, up to 393,750 shares as follows: (1) at our request, up
to 258,750 shares for our directors, officers and business associates and (2) up
to an additional 135,000 shares for preferred stockholders in connection with a
preexisting contractual right between AdForce and those preferred stockholders.
As a result, the number of shares of common stock available for sale to the
general public will be reduced to the extent these persons purchase the reserved
shares. The underwriters will offer to the general public any reserved shares
that are not so purchased on the same basis as the other shares to be sold in
this offering.
 
   
        Before this offering, you could not buy or sell our common stock on a
public market. The initial public offering price for the common stock was
negotiated by AdForce and the underwriters. Among the factors considered in
determining the initial public offering price were prevailing market and
economic conditions, revenues and earnings of AdForce, market valuations of
other companies engaged in activities similar to AdForce, estimates of the
business potential and prospects of AdForce, and the present state of AdForce's
business operations and AdForce's management.
    
 
        Some of the persons participating in this offering may over-allot or
effect transactions that stabilize, maintain or otherwise affect the market
price of the common stock at levels above those that might otherwise prevail in
the open market, including by entering stabilizing bids, effecting syndicate
covering transactions or imposing penalty bids. A stabilizing bid means the
placing of any bid or effecting of any purchase for the purpose of pegging,
fixing or maintaining the price of the common stock. A syndicate covering
transaction means the placing of any bid on behalf of the underwriting syndicate
or the effecting of any purchase to reduce a short position created in
connection with the offering. Penalty bids permit the underwriters to reclaim a
selling concession from a syndicate member in connection with the offering when
shares of common stock sold by the syndicate member are purchased in a syndicate
covering transaction. Stabilizing transactions may be effected on the Nasdaq
National Market, in the over-the-counter market, or otherwise. Stabilizing
transactions, if commenced, may be discontinued at any time.

price of $1,000,011, or $6.865 per share, as part of an equity financing on the
same terms as all other participants in the financing purchased their shares. In
addition, in July 1998, we issued to H&Q Imgis Investors, L.P., a warrant to
purchase up to 5,048 shares of Series D preferred stock at an exercise price of
$6.865 per share, in consideration of agreeing to amendments to our then
effective articles of incorporation. Interests of H&Q Imgis Investors, L.P. and
Hambrecht & Quist California are beneficially owned in part by persons
affiliated with Hambrecht & Quist LLC.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
 
AdForce, Inc.
 
        We have audited the accompanying balance sheets of AdForce, Inc. as of
December 31, 1997 and 1998, and the related statements of operations, and
stockholders' equity, and cash flows for the period from January 16, 1996
(inception) to December 31, 1996 and for the years ended December 31, 1997 and
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
        In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of AdForce, Inc. at
December 31, 1997 and 1998, and the results of its operations and its cash flows
for the period from January 16, 1996 (inception) to December 31, 1996 and for
the years ended December 31, 1997 and 1998, in conformity with generally
accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1998
 
              (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE
               MONTHS ENDED MARCH 31, 1998 AND 1999 IS UNAUDITED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
        Imgis, Inc. was incorporated in the state of California on January 16,
1996. AdForce is a provider of centralized, outsourced ad management and
delivery services on the Internet. AdForce's services offer sophisticated
campaign design, inventory management, targeting, ad delivery, tracking,
measuring and reporting capabilities.
 
   
        AdForce has incurred operating losses to date and had an accumulated
deficit of $24,776,000 and $29,779,000 at December 31, 1998 and March 31, 1999,
respectively. AdForce's activities have been primarily financed through private
placements of equity securities and capital lease financings. AdForce may need
to raise additional capital through the issuance of debt or equity securities
and capital lease financings. Such financing may not be available on terms
satisfactory to AdForce, if at all. If adequate funds are not available, AdForce
may be required to reduce its level of spending.
    
 
    INTERIM FINANCIAL INFORMATION
 
        The financial information as of March 31, 1999 and for the three months
ended March 31, 1998 and 1999 is unaudited but includes all adjustments,
consisting only of normal recurring adjustments, that AdForce's management
considers necessary for a fair presentation of AdForce's operating results and
cash flows for such period. Results for the three month period ended March 31,
1999 are not necessarily indicative of results to be expected for the full
fiscal year of 1999 or for any future period.
 
    USE OF ESTIMATES
 
        The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    CONCENTRATION OF CREDIT RISK
 
        AdForce sells and grants credit for its services to its customers
without requiring collateral or third-party guarantees. To date, all of
AdForce's customers are participants in the Internet industry, including ad
agencies, Web sites, and ad rep firms. Few companies in the Internet industry
have a demonstrated history of profitability, and, accordingly, granting
unsecured credit to such customers carries with it a significant risk of loss.
AdForce monitors its exposure for credit losses and maintains appropriate
allowances. During 1996, AdForce was still in the development stage and had no
revenues. During 1997, two customers accounted for approximately 79% and 13% of
net revenue. One customer accounted for approximately 85% of AdForce's net
accounts receivable at December 31, 1997. During 1998, three customers accounted
for 40%, 16% and 11% of net revenue. Two customers each accounted for
approximately 31% of AdForce's net accounts receivable at December 31, 1998.
During the three months ended March 31, 1999 four customers accounted for 23%,
21%, 20%, and 12% of net revenue. Three of these customers accounted for
approximately 39%, 33%, and 12% of AdForce's net accounts receivable at March
31, 1999.
 
    CASH AND CASH EQUIVALENTS
 
        AdForce considers all highly liquid investments with an original
maturity from the date of purchase of three months or less to be cash
equivalents. As of December 31, 1997 and 1998 and

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1998
 
              (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE
               MONTHS ENDED MARCH 31, 1998 AND 1999 IS UNAUDITED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
March 31, 1999, cash equivalents consisted primarily of investments in money
market accounts and commercial paper, and their cost approximated fair value.
AdForce places its cash and cash equivalents in high-quality U.S. financial
institutions and, to date, has not experienced any losses on any of its
investments.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
        Statement of Financial Accounting Standards ("FAS") No. 107,
"DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS," requires that fair
values be disclosed for most of AdForce's financial instruments. The carrying
amounts of cash and cash equivalents, accounts receivable, note receivable from
stockholder, current liabilities, and capital lease obligations are considered
to be representative of their respective fair values.
 
    INTANGIBLE ASSETS, NET
 
        Intangible assets consist primarily of purchased technology and other
intangibles related to an acquisition accounted for using the purchase method
and the value of the warrant issued to a data vendor. Amortization of the
purchased technology and other intangibles related to the acquisition is
provided on a straight-line basis over the respective useful lives of the
assets, which range from two to three years. Purchased in-process research and
development without an alternative future use was expensed when acquired.
Amortization of the warrant value will be provided on a straight-line basis over
a three year period, beginning upon the earlier of July 14, 1999 or the
commencement of activity under the related agreement.
 
   
        As of December 31, 1998 and March 31, 1999, the Company has accumulated
amortization related to intangible assets of $1,329,000 and $1,697,000,
respectively.
    
 
        AdForce identifies and records impairment losses on intangible assets
when events and circumstances indicate that such assets might be impaired. To
date, no such impairment has been recorded.
 
    DEPRECIATION AND AMORTIZATION
 
        AdForce records property and equipment at cost and calculates
depreciation using the straight-line method over the estimated useful lives of
the assets, generally three to five years. Equipment acquired under capital
leases is amortized on a straight-line basis over the shorter of its lease term
or estimated useful life, generally three to five years.
 
    ADVERTISING COSTS
 
        Advertising costs are charged to expense when incurred. No advertising
was incurred for the period from January 16, 1996 (inception) to December 31,
1996. Advertising expense was $93,000, $125,000, and $270,000 for the years
ended December 31, 1997 and 1998 and the three months ended March 31, 1999,
respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1998
 
              (INFORMATION AS OF MARCH 31, 1999 AND FOR THE THREE
               MONTHS ENDED MARCH 31, 1998 AND 1999 IS UNAUDITED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    REVENUE RECOGNITION
 
        To date, substantially all of AdForce's revenues have been generated
from the provision of Internet advertising management and delivery services for
its customers. AdForce recognizes revenues from these services based on the
number of ads delivered. Revenue is recognized at the time the service is
delivered, provided AdForce does not have any significant remaining obligations
and collection of the resulting receivable is probable. Prepaid amounts for
advertising management and delivery services are recorded as deferred revenue
until the related services are delivered.
 
    STOCK-BASED COMPENSATION
 
        AdForce has elected to follow Accounting Principles Board Opinion No.
25, "ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES" (APB Opinion No. 25), and related
interpretations in accounting for its employee stock options because, as
discussed in Note 7, the alternative fair value accounting provided for under
Statement of Financial Accounting Standards No. 123, "ACCOUNTING FOR STOCK-BASED
COMPENSATION" (FAS 123), requires the use of option valuation models that were
not developed for use in valuing employee stock options. Under APB Opinion No.
25, when the exercise price of AdForce's employee stock options equals the
market price of the underlying stock on the date of grant, no compensation
expense is recognized. See pro forma disclosures of applying FAS 123 included in
Note 7.
 
    RESEARCH AND DEVELOPMENT COSTS
 
        Costs incurred in the development of new software (and substantial
enhancements to existing software) to be used in connection with AdForce's
services are expensed to operations as incurred until technological feasibility
of such software has been established, at which time any additional costs would
be capitalized in accordance with FAS No. 86. Because AdForce believes that its
present process for developing software is completed essentially concurrently
with the establishment of technological feasibility, no research and development
costs have been capitalized to date.
 
    NET LOSS PER SHARE
 
        Basic and diluted net loss per share are presented in conformity with
FAS No. 128, "EARNINGS PER SHARE" ("FAS 128"), for all periods presented.
Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No. 98,
common stock and convertible preferred stock issued or granted for nominal
consideration prior to the anticipated effective date of AdForce's initial
public offering must be included in the calculation of basic and diluted net
loss per share as if they had been outstanding for all periods presented. To
date, AdForce has not had any issuances or grants for nominal consideration. In
accordance with FAS 128, basic and diluted net loss per share has been computed
using the weighted average number of shares of common stock outstanding during
the period, less shares subject to repurchase.
 
    PRO FORMA NET LOSS PER SHARE AND PRO FORMA STOCKHOLDERS' EQUITY
 
        Pro forma net loss per share has been computed as described above and
also gives effect, under Securities and Exchange Commission guidance, to the
conversion of convertible preferred stock not included above that will
automatically convert upon completion of AdForce's initial public offering
(using the as converted method). If the offering contemplated by this prospectus
is consummated, all of the

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
convertible preferred stock outstanding as of March 31, 1999 will automatically
be converted into an aggregate of 9,467,118 shares of common stock. Pro forma
stockholders' equity at March 31, 1999, as adjusted for the conversion of
convertible preferred stock, is disclosed on the balance sheet.
 
        Historical and pro forma basic and diluted net loss per share are as
follows (in thousands, except per share amounts):

have included the shares used in the computation of pro forma net loss per share
as well as approximately 1,953,414, 3,217,546, and 3,575,445 common equivalent
shares related to outstanding options and warrants to purchase common stock not
included above for the years ended December 31, 1997 and 1998 and for the three
months ended March 31, 1999, respectively. The common equivalent shares from
options and warrants would be determined on a weighted average basis using the
treasury stock method.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    COMPREHENSIVE LOSS
 
        In June 1997, the Financial Accounting Standards Board issued FAS No.
130, "REPORTING COMPREHENSIVE INCOME" ("FAS 130"). FAS 130 establishes standards
for the reporting and display of comprehensive income and its components in a
full set of general purpose financial statements and is effective for fiscal
years beginning after December 15, 1997. AdForce adopted FAS 130 in the year
ended December 31, 1998. There was no impact on AdForce's financial statements
as a result of the adoption of FAS 130, as there is no difference between
AdForce's net loss reported and the comprehensive net loss under FAS 130 for the
periods presented.
 
    SEGMENT INFORMATION
 
        In June 1997, the Financial Accounting Standards Board issued FAS No.
131, "DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION" ("FAS
131"). FAS 131 changes the way companies report selected segment information in
annual financial statements and requires companies to report selected segment
information in interim financial reports to stockholders. FAS 131 also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. AdForce adopted FAS 131 in the year ended
December 31, 1998. AdForce operates solely in one segment, the provision of
Internet advertising management and delivery services, and therefore there is no
impact on AdForce's financial statements of adopting FAS 131. For the year ended
December 31, 1998, revenues from customers outside the United States were
$375,000. The majority of this revenue was from customers in Europe.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
        In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued SOP No. 98-1, "ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE
DEVELOPED OR OBTAINED FOR INTERNAL USE." SOP No. 98-1 requires entities to
capitalize certain costs related to internal-use software once certain criteria
have been met. AdForce implemented SOP No. 98-1 on January 1, 1999. The adoption
of SOP No. 98-1 did not have a material impact on its financial position or
results of operations.
 
        In April 1998, the AICPA issued SOP No. 98-5, "REPORTING ON THE COSTS OF
START-UP ACTIVITIES." SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, all start-up costs
that were capitalized in the past must be written off when SOP No. 98-5 is
adopted. AdForce implemented SOP No. 98-5 on January 1, 1999. The adoption of
SOP No. 98-5 did not have a material impact on its financial position or results
of operations.
 
        In June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES." SFAS No.
133 establishes methods for derivative financial instruments and hedging
activities related to those instruments, as well as other hedging activities.
AdForce will be required to implement SFAS No. 133 for the year ending December
31, 2000. Because AdForce does not currently hold any derivative instruments and
does not engage in hedging activities, AdForce does not expect that the adoption
of SFAS No. 133 will have a material impact on its financial position or results
of operations.

2.  BUSINESS COMBINATION
 
   
        In February 1998, AdForce acquired StarPoint Software, Inc.
("StarPoint"), a company that developed software to serve Internet advertising,
for (i) 309,738 shares of Series C preferred stock with a fair value of
$1,465,000 based on the price at which the Series C preferred stock was sold by
the Company in November 1997, (ii) 877,834 shares of common stock with an
aggregate fair value of $1,760,000 based on the deemed fair value of the
Company's common stock at the time of issuance, (iii) options to purchase 48,056
shares of common stock, (iv) $113,000 of debt and (v) $162,000 in acquisition
costs in a transaction that was accounted for as a purchase. The deemed fair
value of the common stock was determined by the Board of Directors after
consideration of the relevant factors, including the current prices of the
Company's preferred stock, the current status of the Company's operations and
key operating factors.
    
 
        The purchase consideration was allocated to the acquired assets and
assumed liabilities based on fair values as follows (in thousands):

                                                              $  3,500

</TABLE>
    
 
        AdForce determined that $100,000 of the purchase price represented
purchased in-process technology that had not yet reached technological
feasibility and had no alternative future use. Accordingly, this amount was
expensed at the time of the acquisition. The value assigned to purchased
in-process technology was determined by identifying research projects in areas
for which technological feasibility had not been achieved and assessing the
completion date of the research and development effort. The state of completion
was determined by estimating the costs and time incurred to date relative to the
costs and time to be incurred to develop the purchased in-process technology
into commercially viable products, estimating the resulting net cash flows only
from the percentage of research and development efforts completed at the date of
acquisition, and discounting the net cash flows back to their present value. The
discount rate of 40% included a factor that took into account the uncertainty
surrounding the successful development of the purchased in-process technology
projects.
 
   
        The value of the purchased technology of $2,600,000 was determined by
discounting expected future cash flows of the existing developed technologies
taking into account the characteristics and applications of the technology, the
size of existing markets and growth rates of existing and future markets, as
well as an evaluation of past and anticipated service-life cycles. The discount
rate of 35% included a factor that took into account the uncertainty surrounding
the successful delivery of the purchased technology.

2.  BUSINESS COMBINATION (CONTINUED)
        The following (unaudited) pro forma summary represents the consolidated
results of operations as if the acquisition of StarPoint had occurred at the
beginning of the period presented and is not intended to be indicative of future
results (in thousands except per share amounts).

        The pro forma disclosures for the year ended December 31, 1998 have been
omitted because they are not materially different from the reported amounts as
the results of operations of StarPoint have been included since February 13,
1998. In-process research and development charges of $100,000 were excluded from
the pro forma net loss and pro forma net loss per share figures for the year
ended December 31, 1997. The number of shares used in the above pro forma per
share calculation assumes that the common stock issued to StarPoint on February
13, 1998 was issued and outstanding for the entire year of 1997. The pro forma
results are not necessarily indicative of what actually would have occurred if
the acquisition had been effected at the beginning of the period presented and
are not intended to be a projection of future results.

4.  RELATED PARTIES
 
        Two of AdForce's founders and current stockholders hold executive
management positions with one of AdForce's customers. Net revenue recognized
from sales to this customer was $260,000 during the year ended December 31,
1998.
 
5.  LICENSE AGREEMENT AND DEMOGRAPHIC DATA AGREEMENT
 
        In July 1998, AdForce entered into a License Agreement and a Demographic
Data Agreement with America Online, Inc. In addition, AdForce sold 728,332
shares of Series E convertible preferred stock to America Online for a purchase
price of $10,000,000. In connection with the sale of Series E convertible
preferred stock to America Online, AdForce also issued to America Online a
warrant to purchase up to 509,831 shares of Series E convertible preferred stock
at an exercise price of $13.73 per share. The warrant is exercisable at any time
on or before July 14, 2003 (See Note 8). AdForce determined the fair value of
the warrants to be $3,686,000 using the Black-Scholes method. Approximately
$1,669,000 of the value of the warrant was attributable to the Series E
preferred stock agreement and approximately $2,019,000 of the value of the
warrant was attributable to the Demographic Data Agreement. AdForce determined
the allocation of the warrant value between the Series E preferred stock
agreement and the Demographic Data Agreement primarily based on the decrease to
the conversion rate (benefit to the Company and its other equity holders) of the
Series D preferred stock as a result of the sale and issuance of the Series E
preferred stock and warrant. The amount related to the Demographic Data
Agreement will be amortized to cost of revenue over the three year term of the
agreement beginning upon the earlier of commencement of activities under the
agreement or July 14, 1999.
 
        Under the License Agreement, AdForce licensed its technology to America
Online and its affiliates to be used internally by America Online and on sites
associated with America Online. The licensed technology includes future
enhancements to AdForce's technology and is warranted to perform according to
its specifications. The license is fully paid, nonexclusive, perpetual,
worldwide and nontransferable except for certain assignments and includes source
code. AdForce can terminate the license only in the event of a material,
uncorrected breach of the License Agreement or Demographic Data Agreement by
America Online. For the duration of the license, if requested, AdForce will
provide technical support, development services and ad serving services on a
cost or cost plus basis if America Online is not in default. AdForce will
provide these services at cost if America Online provides AdForce access to
demographic data under the Demographic Data Agreement and America Online is not
in breach of the Demographic Data Agreement. Otherwise, AdForce can mark up the
cost of our services by certain percentages. Under the License Agreement,
America Online will use commercially reasonable efforts to encourage others
associated with America Online to use AdForce's technology, and AdForce will use
commercially reasonable efforts to encourage its customers to use America Online
in the sale of interactive advertising.
 
        Under the Demographic Data Agreement, America Online may authorize
AdForce to use demographic information about America Online users in connection
with the targeting and delivery of ads to these users. After AdForce has access
to the demographic data, AdForce will pay America Online quarterly fees based on
the greater of a certain percentage of the consideration charged for targeted
advertising or a certain percentage of the incremental revenue charged for the
targeting feature. Such fees will total at least $10,000,000 for the first three
years after America Online provides access to the

demographic data. The term of the Demographic Data Agreement will expire on the
earlier of July 14, 2002 or three years after AdForce has access to the
demographic data. America Online can elect to renew the Demographic Data
Agreement on a year-to-year basis with 90 days' notice on the same terms and
conditions, subject to establishing mutually agreeable minimum annual fees.
America Online can elect to terminate the Demographic Data Agreement upon
payment of a fee to AdForce in the event a third party offers more favorable
terms for access to the demographic data and AdForce does not match such terms.
AdForce has proposed a preliminary implementation schedule that is subject to
America Online's approval. To date, however, AdForce has not had access to the
demographic data and there is no final implementation schedule or procedure for
such access. AdForce has no anticipated time frame for gaining access to the
Demographic Data Agreement.
 
6.  COMMITMENTS
 
        AdForce leases its operating and administrative facilities and certain
equipment under non-cancelable operating lease agreements that expire in April
2004. Rent expense was approximately $81,000, $210,000, $536,000, and $322,000
for the period from January 16, 1996 (inception) to December 31, 1996, for the
years ended December 31, 1997 and 1998 and for the three months ended March 31,
1999, respectively.
 
        During the years ended December 31, 1997 and 1998, AdForce executed five
lease-line agreements for a total of $8,000,000 in lease-line credit
availability. At December 31, 1998, related lease obligations bore interest at
an effective rate of 7.9% to 9.75% and were secured by the related property and
equipment. Approximately $2,110,000 and $169,000 in unused lease-line credit
remained available under these lease agreements at December 31, 1998 and March
31, 1999, respectively.
 
        As of December 31, 1998, minimum lease payments under all noncancelable
lease agreements were as follows (in thousands):

$4,000,000 in lease-line credit availability. Obligations under the lease-line
will be secured by the related equipment and will be payable over a 42 month
period. A total of $1.4 million in borrowings were drawn under this arrangement
during the three month period ended March 31, 1999. Approximately $2.6 million
in unused lease-line credit remained available under this lease agreement at
March 31, 1999.
 
        In February 1999, AdForce executed a noncancellable operating lease for
a facility in Cupertino, California that expires in April 2003. Future minimum

7.  BORROWING ARRANGEMENTS
 
        During 1998, AdForce received funding from a private investor secured by
notes payable totaling $500,000. The notes payable plus accrued interest were
converted into 36,861 shares of Series D convertible preferred stock at a rate
of $13.73 per share during the year ended December 31, 1998.
 
        During the period from January 16, 1996 (inception) to December 31,
1996, AdForce received funding from three investors secured by notes payable
totaling $1,757,000. During the period from January 16, 1996 (inception) to
December 31, 1996, $1,506,000 of these notes payable plus accrued interest were
converted into Series A convertible preferred stock at a rate of $2.51 per
share. The remaining notes payable plus accrued interest of $465,000 were repaid
to the related note holders during the period from January 16, 1996 (inception)
to December 31, 1996.
 
8.  STOCKHOLDERS' EQUITY
 
    GENERAL
 
        In February 1998, AdForce's stockholders approved certain modifications
to AdForce's capital structure, including a two-for-one stock split of AdForce's
common stock, and a modification of the conversion ratio of all shares of
AdForce's preferred stock to common stock. All shares of preferred stock are now
convertible into two shares of common stock. In addition, the stockholders
approved the addition of 1,600,000 shares of common stock to the pool of shares
available for stock option grants under the 1997 Stock Plan. All common share
and per share amounts presented have been adjusted retroactively to reflect the
stock split.

8.  STOCKHOLDERS' EQUITY (CONTINUED)
    CONVERTIBLE PREFERRED STOCK
 
        Each share of convertible preferred stock is convertible into common
stock at the conversion ratio in effect at the time of conversion (two-for-one
at December 31, 1998) and is subject to appropriate adjustment for common stock
splits, stock dividends, and similar transactions. Conversion is automatic upon
the closing of an initial public offering of common stock in which, with respect
to the Series A, B, and C convertible preferred stock, the aggregate gross
proceeds to AdForce are at least $15,000,000 and the minimum offering price is
at least equal to $6.275 per share, and, with respect to the Series D and E
convertible preferred stock, the aggregate proceeds (gross with respect to
Series D and net with respect to Series E) to AdForce are at least $20,000,000
and the minimum offering price is at least equal to $125,000,000 divided by the
number of shares of AdForce's common stock outstanding immediately prior to the
offering, assuming conversion of all convertible securities and the exercise of
all options and warrants. In addition, the Series A, B, and C convertible
preferred stock is convertible upon the written consent or agreement of the
holders of a majority of the respective series of preferred stock.
 
        Each holder of convertible preferred stock is entitled to a number of
votes equal to the number of shares of common stock into which such convertible
preferred stock is convertible.
 
        Each holder of convertible preferred stock is entitled to receive, when
and as declared by the Board of Directors, noncumulative dividends at the annual
rate of $0.20, $0.20, $0.38, $1.10, and $1.10 per share for Series A, B, C, D,
and E convertible preferred stock, respectively, payable in preference and
priority to any payment of any dividend on common stock.
 
        In the event of liquidation, the holders of convertible preferred stock
would be entitled to a liquidation preference equal to $2.51 per share for all
Series B convertible preferred stock, $4.73 per share for all Series C
convertible preferred stock and $13.73 per share for all Series D and E
convertible preferred stock, plus any declared but unpaid dividends on such
share, and if assets remain in the corporation that are legally available for
distribution, the holders of the Series B, C, D, and E convertible preferred
stock would receive from the remaining assets of the corporation available for
distribution to stockholders that portion of such assets equal to their pro rata
share of such assets based on the number of shares of common stock held by all
stockholders of the corporation, assuming the conversion to common stock of all
shares of Series A, B, C, D, and E convertible preferred stock. Then, and only
then, would the holders of Series A convertible preferred stock receive $2.51
per share, plus all declared but unpaid dividends. Any remaining assets would
then be distributed on a pro rata basis among the holders of Series A
convertible preferred stock and the holders of common stock.
 
    COMMON STOCK
 
        At December 31, 1998, AdForce had reserved 10,755,662 shares of its
common stock for issuance upon conversion of the outstanding shares of its
Series A, B, C, D, and E convertible preferred stock and shares of preferred
stock issuable upon the exercise of outstanding warrants, and 2,631,770 shares
of common stock for issuance upon exercise of options outstanding and available
under the 1997 Stock Plan and shares of common stock issuable upon the exercise
of outstanding warrants.
 
        A total of 1,449,620 shares of common stock issued to two of AdForce's
founders in 1996 are subject to certain repurchase rights, held by AdForce, upon
the termination of employment of the

respective founders. Such repurchase rights lapsed immediately with respect to
25% of the shares and lapse ratably with respect to the remaining shares over 36
months beginning in June 1996. During 1998, the founders ceased their employment
with AdForce. AdForce elected not to exercise its repurchase right with respect
to the remaining 256,195 shares subject to repurchase at that time. Compensation
expense of $1,407,000 was recorded in 1998 related to such shares based on the
difference between the exercise price and the fair value of such shares at the
time the founders ceased employment with AdForce.
 
        At December 31, 1998, 562,500 shares of common stock held by an officer
were subject to repurchase by AdForce at their original purchase price of $0.125
per share. Such repurchase rights lapse ratably over the 48-month vesting period
of the underlying options to purchase common stock.
 
        A total of 800,000 shares of common stock issued in conjunction with
AdForce's acquisition of StarPoint to three of StarPoint's founders, who are now
employees of AdForce, were subject to certain repurchase rights held by AdForce.
At December 31, 1998, 266,667 of these shares of common stock remained subject
to repurchase. The repurchase rights lapsed as to 22/48 of the shares on the
date of acquisition, as to 9/48 of the shares after the employees had completed
nine months of continuous employment at AdForce and as to 1/48 of these shares
each month thereafter.
 
    NOTE RECEIVABLE FROM STOCKHOLDER
 
        During 1997, AdForce received a note receivable from a stockholder of
AdForce upon his exercise of an option to purchase 900,000 shares of common
stock. As of December 31, 1998, 562,500 of the shares issued were subject to
repurchase by AdForce at the original exercise price. The repurchase rights
lapse ratably over the 48 month vesting period of the underlying option. The
note bears interest at 6.8% and is secured by the related stock. The note and
related interest is being forgiven ratably over a period of four years of
service/employment. The Company is recording compensation expense related to the
forgiveness of the note as the note is forgiven.

8.  STOCKHOLDERS' EQUITY (CONTINUED)
 
        Warrants to purchase 6,142 shares of common stock, included above,
expire on the earlier of October 15, 2007 or the filing by AdForce of an initial
public offering. Warrants to purchase 36,998 and 10,925 shares of Series C and
Series D convertible preferred stock, included above, expire on the later of
December 2, 2007 and September 29, 2008, respectively, or five years subsequent
to the filing by AdForce of an initial public offering. Warrants to purchase
36,430 shares of Series D convertible preferred stock and 509,831 shares of
Series E convertible preferred stock, included above, expire on the later of
July 14, 2003 or the closing of any merger, tender offer, or other transaction
in which all of the holders of AdForce's outstanding common stock and preferred
stock (if any) receive only cash or cash and other securities payable only in
cash. Warrants to purchase 400,000 shares of common stock issued to a
demographic data vendor in April 1997, with a fair value of $48,000 and a ten
year life, were exercised for total consideration of $2,000 during 1998 but are
subject to certain repurchase rights held by AdForce. These repurchase rights
lapsed as to 25% of the shares in April 1997 and 2.08% of the shares each month
thereafter. As of December 31, 1998, 133,360 shares acquired pursuant to this
warrant exercise remained subject to AdForce's repurchase right.
 
        The value of the warrants granted to third parties, excluding the value
attributable to equity investments of approximately $1.9 million, is being
charged to the related expense over the term of the respective agreements.
AdForce recognized expenses of $23,000 and $56,000 during the years ended
December 31, 1997 and 1998, respectively, related to the estimated fair market
value of these warrants. The value of each of the warrants has been determined
using the Black-Sholes method, with an expected dividend yield of zero, a
risk-free interest rate of 5%, and a volatility factor of 20%, except for the
warrant to purchase shares of Series D and Series E preferred stock issued to
private investors for which a volatility factor of 55% was used. The lives used
to value each of the warrants was based on the term of each warrant as set forth
in the preceding table or described in the preceding paragraph.
 
    STOCK OPTION PLANS
 
        AdForce has elected to follow APB Opinion No. 25 and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FAS
No. 123, "ACCOUNTING FOR STOCK-BASED COMPENSATION" ("FAS 123"), requires use of
option valuation models that were not developed for use in valuing employee
stock options. Under APB Opinion No 25, when the exercise price of AdForce's
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recognized.
 
        During 1997, AdForce adopted the 1997 Stock Plan (the "Plan"). Under the
Plan, options to purchase common stock may be granted at no less than 85% of the
fair value of the underlying common stock on the date of the grant, as
determined by the Board of Directors. Options generally have a maximum term of
10 years and are exercisable immediately, but vest over a 48-month period. Under
the Plan, an optionee may exercise part or all of the options prior to the
stated vesting date. However, unvested shares are subject to repurchase, at
AdForce's option, upon a stockholder's termination of employment for any reason.
As of December 31, 1998, 763,088 of the shares issued upon exercise of stock
options, including the options exercised by an officer of AdForce that are
discussed under "NOTE RECEIVABLE FROM SALE OF COMMON STOCK," were subject to
repurchase by AdForce at the exercise price.

8.  STOCKHOLDERS' EQUITY (CONTINUED)
        All outstanding options to purchase common stock of AdForce were
exercisable at December 31, 1998. As of December 31, 1998, options to purchase
314,101 shares of common stock were vested.
 
   
        In connection with the grant of certain options to employees during the
year ended December 31, 1998 and the three months ended March 31, 1999, AdForce
recorded deferred stock compensation of approximately $3,974,000 and $4,139,000,
respectively, between the exercise prices of those options at their respective
dates of grant and the deemed fair values for accounting purposes of the shares
of common stock subject to such options. Such amounts are included as a
reduction of stockholders' equity and are being amortized on a graded vesting
method. The compensation expense of $1,172,000 and $1,118,000 during 1998 and
the three months ended March 31, 1999, respectively, relate to options awarded
to employees in all operating expense categories, as well as employees in data
center operations. These amounts have not been separately allocated between
operating expense categories. In April and May 1999, the Company granted options
to purchase approximately 722,350 shares of common stock with exercise prices
ranging from $8.50 to $11.50 per share and expects to record additional deferred
compensation of approximately $4.4 million related to these grants for the
difference between the exercise price and the current deemed fair value.
    
 
        Pro forma information regarding net loss is required by FAS 123,
computed as if AdForce had accounted for its employee stock options granted or
otherwise modified under the fair value-based accounting method of that
statement. The value for these options was estimated at the date of grant using
the minimum value method with the following weighted average assumptions:

        The weighted average fair value of options granted during 1997, 1998 and
the three months ended March 31, 1999 with an exercise price equal to the fair
value of AdForce's common stock on the date of grant was $0.06, $0.06, and
$1.63, respectively. The weighted-average fair value of options granted during
1998 and during the three month period ended March 31, 1999 with an exercise
price below the deemed fair value of AdForce's common stock on the date of grant
was $3.70 and $6.31, respectively.

8.  STOCKHOLDERS' EQUITY (CONTINUED)
 
    1999 EQUITY INCENTIVE PLAN
 
        In February 1999, the Board of Directors adopted the 1999 Equity
Incentive Plan and reserved 2,000,000 shares for issuance thereunder, subject to
stockholder approval. The 1999 Equity Incentive Plan will become effective on
the effective date of the initial public offering and will serve as the
successor to the Plan. Options granted under the Plan before its termination
will remain outstanding according to their terms, but no further options will be
granted under the Plan after the effective date of the initial public offering.
The 1999 Equity Incentive Plan will terminate in February 2009, unless sooner
terminated in accordance with its terms. The 1999 Equity Incentive Plan
authorizes the award of incentive stock options and nonqualified stock options,
restricted stock awards and stock bonuses.
 
    1999 EMPLOYEE STOCK PURCHASE PLAN
 
        In February 1999, the Board of Directors adopted the 1999 Employee Stock
Purchase Plan and reserved a total of 300,000 shares of common stock for
issuance thereunder, subject to stockholder approval. On each January 1, the
aggregate number of shares reserved for issuance under the 1999 Employee Stock
Purchase Plan will be increased automatically by the number of shares purchased
under the 1999 Employee Stock Purchase Plan in the preceding calendar year. The
aggregate number of shares issued over the term of the 1999 Employee Stock
Purchase Plan may not exceed 3,000,000 shares. The 1999 Employee Stock Purchase
Plan will become effective on the effective date of the initial public offering.
Employees generally will be eligible to participate in the 1999 Employee Stock
Purchase Plan if they are customarily employed by AdForce or its parent or any
subsidiaries that AdForce designates for more than 20 hours per week and more
than five months in a calendar year. Under the 1999 Employee Stock Purchase
Plan, eligible employees will be permitted to acquire shares of AdForce's common
stock through payroll deductions. Eligible employees may select a rate of
payroll deduction between 2% and 10% of their compensation and are subject to
certain maximum purchase limitations described in the 1999 Employee Stock
Purchase Plan. Each offering period under the 1999 Employee Stock Purchase Plan
will be for two years and consist of six-month purchase periods. The first
offering period is expected to begin on the first business day on which price
quotations for AdForce's common stock are available on the Nasdaq National
Market. Offering periods and purchase periods thereafter will begin on February
1 and August 1. The purchase price for AdForce's common stock purchased under
the 1999 Employee Stock Purchase Plan is 85% of the lesser of the fair market
value of AdForce's common stock on the first day of the applicable offering
period or the last day of each purchase period. The 1999 Employee Stock Purchase
Plan will terminate in February 1999, unless earlier terminated pursuant to the
terms of the 1999 Employee Stock Purchase Plan. The Board of Directors will have
the authority to amend, terminate, or extend the term of the 1999 Employee Stock
Purchase Plan.
 
    1999 DIRECTORS STOCK OPTION PLAN
 
        In February 1999, the Board of Directors adopted the 1999 Directors
Stock Option Plan and reserved a total of 200,000 shares of common stock for
issuance under the 1999 Directors Stock Option Plan, subject to stockholder
approval. Members of the Board of Directors who are not employees of AdForce, or
any parent, subsidiary or affiliate of AdForce, are eligible to participate in
the 1999 Directors Stock Option Plan. Option grants under the 1999 Directors
Stock Option Plan are automatic and nondiscretionary, and the exercise price of
the options is the fair market value of the common stock on the

date of grant. Each eligible director who first becomes a member of the Board of
Directors on or after the effective date of the initial public offering will
initially be granted an option to purchase 10,000 shares of common stock on the
date he or she becomes a member of the Board of Directors. Each eligible
director who first becomes a member of the Board of Directors prior to the
effective date of the initial public offering will receive an initial grant
immediately following the first annual meeting of stockholders of AdForce after
the effective date of the initial public offering, provided that he or she is
elected a member of the Board of Directors at the first annual meeting of
stockholders. Immediately following each annual meeting of stockholders of
AdForce, each eligible director will automatically be granted an additional
option to purchase 5,000 shares of common stock if he or she has served
continuously as a member of the Board of Directors for a period of at least one
year since the date of his or her initial grant under this Plan. The options
have ten-year terms. They will terminate seven months following the date the
director ceases to be a director or a consultant to AdForce, or twelve months if
the termination is due to death or disability. All options granted under the
1999 Directors Stock Option Plan will vest as to 25% of the shares on the first
anniversary of the date of grant and as to 2.08333% of the shares each month
thereafter, provided the optionee continues as a member of the Board of
Directors or as a consultant to AdForce. In the event of a merger or other
transaction in which AdForce is not the surviving corporation, all options
issued under the 1999 Directors Stock Option Plan will accelerate and become
exercisable in full prior to the consummation of the transaction.
 
9. ACQUISITION OF TECHNOLOGY AND OPERATING RIGHTS
 
        In January 1996, AdForce assumed the assets and liabilities of Iron
Mountain Global Information Systems, Inc. in exchange for a combination of
1,720,000 shares of common stock in AdForce valued at $0.005 per share, the
assumption of notes payable of $214,000 and an agreement to make a cash payment
of $106,000 to an investor in Iron Mountain Global Information Systems, Inc. The
net assets acquired included in-process software technology for use in the
business of Internet ad-serving. However, this technology was initially
developed for online real estate advertising and inquiry and subsequently proved
to be unusable for AdForce's current Internet advertising processes. This
software technology was abandoned during 1996 in favor of the development of new
software technology to satisfy projected market needs. Accordingly, the entire
value assigned to the acquired technology of $319,000 was expensed to Research
and Development during the period from January 16, 1996 (inception) to December
31, 1996.
 
10. INCOME TAXES
 
        The difference between the amount of income tax benefit recorded and the
amount of income tax benefit calculated using the U.S. federal statutory rate of
34% is due to net operating losses not being benefitted. Accordingly, there is
no provision for income taxes for the period from January 16, 1996 (inception)
to December 31, 1996 and the years ended December 31, 1997 and 1998.

        FASB Statement No. 109 provides for the recognition of deferred tax
assets if realization of such assets is more likely than not. Based upon the
weight of available evidence, which includes AdForce's historical operating
performance and the reported cumulative net losses in all prior years, AdForce
has provided a full valuation allowance against its net deferred tax assets.
 
        The valuation allowance increased by approximately $1,300,000 and
$2,400,000 during the period from January 16, 1996 (inception) to December 31,
1996 and the year ended December 31, 1997, respectively.
 
        As of December 31, 1998, AdForce had federal and state net operating
loss carryforwards of approximately $17,000,000. AdForce also had federal and
state research and development tax credit carryforwards of approximately
$250,000 and $130,000, respectively. The net operating loss and tax credit
carryforwards, if not utilized, will expire at various dates beginning in 2004.
 
        Utilization of the net operating loss and tax credit carryforwards may
be subject to a substantial annual limitation due to the "change in ownership"
provisions of the Internal Revenue Code of 1986, as amended, and similar state
provisions. The annual limitation may result in expiration of net operating loss
and tax credit carryforwards before utilization.
 
11. SUBSEQUENT EVENTS

                         NOTES TO FINANCIAL STATEMENTS
 
                                  MAY 31, 1997
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
        StarPoint Software Inc. ("StarPoint") was incorporated on August 8, 1996
to provide software products for serving Internet advertising. StarPoint has
developed technology that is used to electronically place advertisements on
Internet web pages using highly sophisticated targeting techniques. It has
deployed such technology as part of a marketed software offering that
facilitates the delivery of Internet ads for a variety of market segments,
including (i) advertisers; (ii) advertising agencies; (iii) advertising
representation firms; and (iv) Internet service providers, content providers
(i.e., "Web sites"), and search engines. StarPoint's principal activities to
date have been recruiting personnel, performing research and development, and
building a sales and marketing function. StarPoint was in the development stage
through May 1997, when it first began generating revenues.
 
    INTERIM FINANCIAL STATEMENTS
 
        The accompanying balance sheet as of November 30, 1997 and the
statements of operations and cash flows for the period from August 8, 1996
(inception) through November 30, 1996 and the six month period ended November
30, 1997 are unaudited. In the opinion of management, the unaudited financial
statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting of normal recurring entries,
necessary for a fair statement of the financial position, result of operations,
and cash flows for the interim periods. The results of operations for the
six-month period ended November 30, 1997 are not necessarily indicative of
operating results to be expected for the full fiscal year.
 
    USE OF ESTIMATES
 
        The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    CONCENTRATION OF CREDIT RISK
 
        StarPoint markets, sells, and grants credit for its products to its
customers without requiring collateral or third-party guarantees. To date, all
of StarPoint's customers are participants in the Internet industry. Only a few
of all participants in the Internet industry have a demonstrated history of
profitability, and accordingly, unsecured credit granted to such customers
carries with it a greater risk of loss. StarPoint monitors its exposure for
credit losses and maintains appropriate allowances.
 
    DEPRECIATION AND AMORTIZATION
 
        StarPoint records property and equipment at cost and calculates
depreciation using an accelerated depreciation method over the estimated useful
life of the assets, generally three to seven years.
 
    ADVERTISING COSTS
 
        Advertising costs are charged to expense when incurred. Advertising
expense was $19,294 for the period from August 8, 1996 (inception) through May
31, 1997.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    REVENUE RECOGNITION
 
        StarPoint licenses software to end users under noncancelable license
agreements. Software license revenue is generally recognized at the time the
product has been shipped, provided StarPoint does not have any significant
remaining obligations and collection of the resulting receivable is probable.
Maintenance revenue is recognized ratably over the term of the related
agreement, which in most cases is one year. Revenue is recorded net of revenue
allowances.
 
    STOCK-BASED COMPENSATION
 
        StarPoint accounts for employee stock option grants in accordance with
Accounting Principals Board Opinion No. 25, "ACCOUNTING FOR STOCK ISSUED TO
EMPLOYEES" (APB Opinion No. 25). StarPoint grants stock options for a fixed
number of shares to employees with an exercise price equal to the fair value of
the shares at the date of grant and, accordingly, recognizes no compensation
expense for the employee stock option grants.
 
    RESEARCH AND DEVELOPMENT COSTS
 
        Costs incurred in the development of new software (and substantial
enhancements to existing software) used in the processes of StarPoint's Internet
advertisement serving services are expensed to operations as incurred until
technological feasibility of such software has been established, at which time
any additional costs would be capitalized in accordance with Statement of
Financial Accounting Standards No. 86, "ACCOUNTING FOR THE COSTS OF COMPUTER
SOFTWARE TO BE SOLD, LEASED, OR OTHERWISE MARKETED" (FAS 86). Because StarPoint
believes that its present process for developing software is essentially
completed concurrently with the establishment of technological feasibility, no
costs have been capitalized to date.

        Property and equipment consist of the following:

3.  COMMITMENTS
 
        StarPoint has leased its facility under a noncancelable operating lease
agreement which expires in November 1997. As of May 31, 1997, minimum lease
payments under the noncancelable lease agreement for the year ended May 31, 1998
were $37,125.
 
        Rent expense was approximately $60,500 for the period from August 8,
1996 (inception) through May 31, 1997.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
4.  CONVERTIBLE PROMISSORY NOTES PAYABLE
 
        During the period from August 8, 1996 (inception) through May 31, 1997,
StarPoint received funding from investors secured by convertible promissory
notes payable totaling $860,000. The notes bear interest at 6.5% and mature on
demand or on the stated maturity date which is from November 29, 1997 to March
4, 1998. Prior to the maturity date, the promissory notes and accrued interest
will automatically convert into preferred stock upon the closing of an equity
financing of StarPoint's preferred stock for an aggregate consideration of at
least $1,500,000.
 
        In connection with the convertible promissory notes issued, StarPoint
has issued warrants to purchase $172,000 of preferred stock at an exercise price
equal to the lower of $2.00 or the issuance price of the preferred stock at the
time of the financing. The warrants are exercisable at any time prior to
expiration and will expire at the earlier of: (i) five years, (ii) the merger or
consolidation of StarPoint into a third party pursuant to which StarPoint's
shareholders own less than 50% of the surviving entity, (iii) the sale of
substantially all of the assets of StarPoint, or (iv) the closing of an initial
public offering of common stock. StarPoint has allocated $49,880 of the proceeds
received from the issuance of the promissory notes to the value of the warrants.
The principal amounts of the convertible promissory notes were reduced by the
value assigned to the warrants, and such amount is being recognized as
additional interest expense over the life of the notes. StarPoint recognized
interest expense of $17,442 related to the estimated fair market value of the
warrants.
 
        As of May 31, 1997, StarPoint has reserved 526,624 shares of preferred
stock for issuance upon conversion of the convertible promissory notes and
exercise of stock purchase warrants. No warrants were exercised in the period
from August 8, 1996 (inception) through May 31, 1997.
 
5.  SHAREHOLDERS' EQUITY (NET CAPITAL DEFICIENCY)
 
    COMMON STOCK
 
        As of May 31, 1997, StarPoint has reserved 741,000 shares of its common
stock for issuance upon exercise of options outstanding and available under the
1996 Stock Plan.
 
        A total of 2,470,000 shares of common stock issued in 1996 to three of
StarPoint's founders and a consultant are subject to certain repurchase rights
held by StarPoint. Such repurchase rights lapse 10% immediately, 15% in August
1997, and the remainder ratably over 48 months beginning in September 1997. As
of May 31, 1997, 2,223,000 shares of common stock are subject to repurchase by
StarPoint at the original purchase price of $0.01 per share.
 
    STOCK OPTION PLANS
 
        StarPoint has elected to follow APB Opinion No. 25, and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under
Statement of Financial Accounting Standards No. 123, "ACCOUNTING FOR STOCK-BASED
COMPENSATION" (FAS 123), requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB Opinion 25, when
the exercise price of StarPoint's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized.
 
        During the period from August 8, 1996 (inception) through May 31, 1997,
StarPoint adopted the 1996 Stock Plan (the Plan). Under the Plan, up to 741,000
shares of StarPoint's common stock may be granted to directors, employees, and
certain consultants. Under the Plan, options to purchase common

grant as determined by the Board of Directors. Options generally vest over a
48-month period and have a maximum term of ten years.

</TABLE>
 
        All outstanding options to purchase common stock of StarPoint were
exercisable at May 31, 1997. As of May 31, 1997, options to purchase 7,292
shares of common stock were vested. The weighted average remaining contractual
life of those options is approximately 9.7 years.
 
        Pro forma information regarding net income (loss) is required by FAS
123, which also requires that the information be determined as if StarPoint has
accounted for its employee stock options granted subsequent to December 31, 1994
under the fair value method of FAS 123. The fair value of these options was
estimated at the date of grant using the minimum-value method option-pricing
model. The following weighted average assumptions were used for the period ended
May 31, 1997: (i) a risk-free interest rate of 5%, (ii) a dividend yield of
zero, and (iii) a weighted average expected life of the option of four years.
The weighted average fair value of options granted during 1997 was $0.03.
 
        The effect of applying FAS 123 to StarPoint's stock option awards
resulted in a pro forma net loss of $1,066,915 for the period from August 8,
1996 (inception) through May 31, 1997.
 
6.  INCOME TAXES
 
        As of May 31, 1997, StarPoint had federal and state net operating loss
carryforwards of approximately $1,100,000. The net operating loss carryforwards
will expire at various dates beginning in 2005 through 2012, if not utilized.
 
        Utilization of the net operating losses may, in the future, be subject
to a substantial annual limitation due to the "change in ownership" provisions
of the Internal Revenue Code of 1986, as amended, and similar state provisions.
The annual limitation may result in the expiration of net operating losses
before utilization.
 
        As of May 31, 1997, StarPoint had deferred tax assets of approximately
$400,000. The net deferred tax asset has been fully offset by a valuation
allowance. The net valuation allowance increased by $400,000 during the period
from August 8, 1996 (inception) through May 31, 1997. Deferred tax assets
primarily relate to net operating loss carryforwards.
 
7.  SUBSEQUENT EVENTS
 
        In June and October 1997, StarPoint amended the terms of the convertible
promissory notes to allow the holders to convert the outstanding principal and
accrued interest into Series B preferred stock at a conversion price of $0.60
per share upon the earlier of the maturity date or a change in control.

7.  SUBSEQUENT EVENTS (CONTINUED)
        In June, July, and October 1997, StarPoint received funding from
investors secured by convertible promissory notes payable totaling $192,500. The
notes bear interest at 6.5% and mature on demand or on the stated maturity date,
which is from June 13, 1998 to October 16, 1998. The promissory notes are
convertible into preferred stock at the then fair market value of such stock. In
connection with the convertible promissory notes issued, StarPoint has issued
warrants to purchase $96,250 of preferred stock at an exercise price equal to
the lower of $2.00 or the issuance price of the preferred stock at the time of
the financing.
 
        In December 1997, StarPoint entered into a definitive agreement to merge
with AdForce, Inc. (formerly Imgis, Inc.), a company providing a comprehensive
service infrastructure that facilitates the planning, scheduling, targeting,
delivery, monitoring, analysis, reporting of, and accounting for advertising on
the Internet. The merger became effective on February 13, 1998 and was accounted
for as a purchase by AdForce, Inc. AdForce, Inc. assumed all assets and
liabilities of StarPoint, issued 877,834 shares of common stock in exchange for
all outstanding common stock of StarPoint, and issued 309,738 shares of Series C
preferred stock for all outstanding preferred stock of StarPoint.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
        Section 145 of the Delaware General Corporation Law authorizes a court
to award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Securities
Act").
 
        As permitted by the Delaware General Corporation Law, the Registrant's
Second Amended and Restated Certificate of Incorporation, which will become
effective upon the closing of this offering, includes a provision that
eliminates the personal liability of its directors for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Registrant or its stockholders, (ii)
for acts or omissions not in good faith or that involve intentional misconduct
or a knowing violation of law, (iii) under section 174 of the Delaware General
Corporation Law (regarding unlawful dividends and stock purchases) or (iv) for
any transaction from which the director derived an improper personal benefit.
 
        As permitted by the Delaware General Corporation Law, the Bylaws of the
Registrant provide that (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, provided that any indemnified officer and director acted in
good faith and in a manner which such officer and director reasonably believed
to be in or not opposed to the Registrant's best interests, (ii) the Registrant
may indemnify its other employees and agents as set forth in the Delaware
General Corporation Law, (iii) the Registrant is required to advance expenses,
as incurred, to its directors and officers in connection with a legal proceeding
to the fullest extent permitted by the Delaware General Corporation Law, subject
to certain very limited exceptions and (iv) the rights conferred in the Bylaws
are not exclusive.
 
        The Registrant intends to enter into Indemnification Agreements with
each of its current directors and officers to give such directors and officers
additional contractual assurances regarding the scope of the indemnification set
forth in the Registrant's Second Amended and Restated Certificate of
Incorporation and to provide additional procedural protections. At present,
there is no pending litigation or proceeding involving a director, officer or
employee of the Registrant regarding which indemnification is
 
                                      II-1
<PAGE>
sought, nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification.
 
        Reference is also made to Section 7 of the Underwriting Agreement, which
provides for the indemnification of officers, directors and controlling persons
of the Registrant against certain liabilities. The indemnification provision in
the Registrant's Second Amended and Restated Certificate of Incorporation,
Bylaws and the Indemnification Agreements entered into between the Registrant
and each of its directors and officers may be sufficiently broad to permit
indemnification of the Registrant's directors and officers for liabilities
arising under the Securities Act.
 
        The Registrant, with approval by the Registrant's Board of Directors,
expects to obtain directors' and officers' liability insurance.
 
        See also the undertakings set out in response to Item 17.
 
        Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 17.  UNDERTAKINGS.
 
        The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement certificates
in such denominations and registered in such names as required by the
Underwriters to permit prompt delivery to each purchaser.
 
        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
        The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

Gentlemen/Ladies:

     At your request, we have examined the Registration Statement on Form S-1
(File Number 333-73231) (the "REGISTRATION STATEMENT") filed by you with the
Securities and Exchange Commission (the "COMMISSION") on or about March 2, 1999,
as subsequently amended in connection with the registration under the Securities
Act of 1933, as amended, of an aggregate of 5,175,000 shares of your Common
Stock (the "STOCK").

     In rendering this opinion, we have examined the following:

     (1)  your registration statement on Form 8-A (File Number 000-25497) filed
          with the Commission on May 4, 1999;

     (2)  the Registration Statement, together with the Exhibits filed as a part
          thereof;

     (3)  the prospectuses prepared in connection with the Registration
          Statement;

     (4)  the minutes of meetings and actions by written consent of the
          stockholders and Board of Directors that are contained in your minute
          books and the minute books of your predecessor, Imgis, Inc., a 
          California corporation ("IMGIS CALIFORNIA"), that are in our 
          possession;

     (5)  the stock records for both you and Imgis California that you have
          provided to us (consisting of a list of stockholders and photocopies 
          of stock certificates and a list of option and warrant holders 
          respecting your capital stock and of any other rights to purchase 
          capital stock verifying the number of such issued and outstanding 
          securities); and

     (6)  a Management Certificate addressed to us and dated of even date
          herewith executed by the Company containing certain factual and other
          representations.

     In our examination of documents for purposes of this opinion, we have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity and completeness of all documents submitted
to us as originals, the conformity to originals and completeness of all
documents submitted to us as copies, the legal capacity of all natural persons

     As to matters of fact relevant to this opinion, we have relied solely upon
our examination of the documents referred to above and have assumed the current
accuracy and completeness of the information obtained from public officials and
records referred to above.  We have made no independent investigation or other
attempt to verify the accuracy of any of such information or to determine the
existence or non-existence of any other factual matters; HOWEVER, we are not
aware of any facts that would cause us to believe that the opinion expressed
herein is not accurate.

     We are admitted to practice law in the State of California, and we express
no opinion herein with respect to the application or effect of the laws of any
jurisdiction other than the existing laws of the United States of America and
the State of California and (without reference to case law or secondary sources)
the existing Delaware General Corporation Law.

     In connection with our opinion expressed below, we have assumed that, at or
prior to the time of the delivery of any shares of the Stock, the Registration
Statement and the registration statement on Form 8-A will have been declared 
effective under the Securities Act of 1933, as amended, that the registration 
will apply to such shares of the Stock and will not have been modified or 
rescinded and that there will not have occurred any change in law affecting 
the validity or enforceability of such shares of the Stock.

     Based upon the foregoing, it is our opinion that the up to 5,175,000 shares
of the Stock to be issued and sold by you, when issued and sold in accordance in
the manner referred to in the relevant prospectus associated with the
Registration Statement, will be validly issued, fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us, if any, in the
Registration Statement, the prospectus constituting a part thereof and any
amendments thereto.

     This opinion speaks only as of its date and we assume no obligation to
update this opinion should circumstances change after the date hereof.  This
opinion is intended solely for your use as an exhibit to the Registration
Statement for the purpose of the above sale of the Stock and is not to be relied
upon for any other purpose.

                                        Very truly yours,

                                        FENWICK & WEST LLP

                       ADFORCE SERVICES AGREEMENT

This Agreement (the "Agreement") is entered into between IMGIS, Inc., a 
California corporation ("IMGIS"), with offices at 10101 North DeAnza Blvd., 
Suite 210, Cupertino, California 95014 and 2CAN Media, a Delaware corporation 
("COMPANY"), with offices at 20700 Ventura Blvd., Woodland Hills, CA 91364.

1.  ADFORCE SERVICE DEFINITION. The AdForce service is an Internet 
    advertising administration system that will allow 2CAN Media and its ad 
    sales and network clients, defined as Web publishers ("Clients") to 
    manage advertising on Client's Web sites or similar on-line services. As 
    part of the AdForce service, IMGIS will provide 2CAN Media with the 
    AdForce "client" software application ("Application Software"), with 
    which 2CAN Media will be able to (a) generate ad tags, (b) schedule 
    advertising to run in the online environments in which 2CAN Media places 
    those ad tags and (c) generate reports on such advertising. In addition, 
    IMGIS will maintain an AdForce server complex from which IMGIS will 
    electronically deliver advertising scheduled by 2CAN Media to the online 
    environments containing the ad tags placed by 2CAN Media and its 
    Clients. The delivery of "Impressions," defined as the transmission of 
    advertisements or other content by AdForce, will be verified by monthly 
    third-party audits of the AdForce service, conducted by the Audit Bureau 
    of Verification Services, Inc. or another third party chosen by IMGIS in 
    its sole discretion. The AdForce service includes targeting features as 
    listed in Exhibit B. The AdForce service includes a suite of standard 
    reports available in the AdForce system and listed in Exhibit B. Features 
    added to the AdForce service in the future, including, but not limited 
    to, demographic and psychographic targeting; will be considered part of 
    the AdForce service covered in this Agreement and may be subject to 
    additional fees, which fees will be subject to IMGIS sole discretion.

2.  ADFORCE SERVICE AND SUPPORT. In addition to the functionality described 
    in Section 1, IMGIS will provide 2CAN Media with telephone customer 
    support from the hours of 6am to 6pm Pacific Time, Monday-Friday, 
    excluding major holidays and 7 day a week, 24-hour-a-day access to IMGIS 
    technical support via phone and pager. 2CAN Media will be responsible 
    for providing support to its Clients and advertisers unless IMGIS is 
    providing Platinum Service. IMGIS will provide full-service scheduling of 
    2CAN Media's advertising campaigns by IMGIS personnel ("Platinum 
    Service"), including manual insertions and campaign modifications for a 
    period of sixty (60) days from the execution date of this agreement 
    (Platinum Service). Platinum Service will be available to 2CAN Media 
    after this initial sixty (60) day period at an additional fee to be 
    determined.

    service as its exclusive ad serving technology. 2CAN Media agrees to 
    implement the ad tags on its Clients' sites as described in the AdForce 
    User Guide and Help documentation. 2CAN Media also agrees to use best 
    commercial efforts to schedule all advertising for 2CAN's Client sites 
    or on-line properties on the AdForce service. If 2CAN Media elects to 
    have IMGIS process insertion and modification orders on 2CAN Media's 
    behalf, 2CAN Media agrees to supply IMGIS with the information necessary 
    to schedule and/or modify ad campaigns at least 12 hours in advance of 
    campaign initiation. Should the average file size of 2CAN Media's 
    advertisements exceed 12 kilobytes, as determined by IMGIS on a monthly 
    basis, 2CAN agrees to pay the incremental fee listed in Exhibit A to 
    compensate for higher bandwidth costs. 2CAN Media agrees to provide 
    IMGIS with non-binding volume forecasts of Impressions to be delivered 
    using the AdForce service for the upcoming 12 months on a rolling 30-day 
    basis. 2CAN Media agrees to respond favorably to inquiries from the 
    press, potential investors, customers and future customers regarding the 
    AdForce service, IMGIS and the relationship between parties. 
    Additionally, 2CAN Media agrees to participate in, and make inventory 
    available to, upcoming AdForce product functionality currently code 
    named "Cross Network Buying" which will allow media buyers and other web 
    publishers to electronically access available inventory through the 
    AdForce service. (release date TBD).

     2.1  ACCESS TO DEMOGRAPHIC DATA.

          (a) Following the Commencement Date, in accordance with the terms of
     the Implementation Schedule, AOL agrees to permit IMGIS to access codes
     embodying

     Demographic Data (using a one key to many user matching algorithm) with
     respect to AOL Users, access to which codes shall be provided by AOL at the
     time that each AOL User uses the AOL Brand Service to request delivery of
     an advertisement to an Internet site other than AOL.com, an Internet site
     of any AOL Affiliate or any Covered AOL Partner Site. IMGIS shall access
     such Demographic Data following the Commencement Date for the sole purpose
     of serving Targeted interactive advertisements using the IMGIS AdForce
     System for or on behalf of Third Parties that have contracted with IMGIS
     for the serving of Targeted interactive advertisements and for no other
     purpose, subject to the limitations and conditions set forth in Article 3
     below and elsewhere herein. IMGIS shall provide to AOL, on a quarterly
     basis, a written report signed by an officer of IMGIS describing IMGIS' use
     of Demographic Data during each quarter, including, without limitation, the
     Third Parties that have contracted with IMGIS for the serving of Targeted
     interactive advertisements using Demographic Data.

          (b) Following the Commencement Date, in accordance with the terms of
     the Implementation Schedule, AOL, at its option, may permit IMGIS to access
     codes embodying Demographic Data (using a one key to many user matching
     algorithm) with respect to AOL Users, access to which codes shall be
     provided by AOL at the time that each AOL User (i) uses the AOL Brand
     Service to request delivery of an advertisement to AOL.com, an Internet
     site of an AOL Affiliate or a Covered AOL Partner Site, if AOL has
     requested that IMGIS provide Ad Serving Services for such Internet site
     under the License Agreement or (ii) receives a screen page on the AOL
     Network on which appears an interactive advertisement, if AOL has requested
     that IMGIS provide Ad Serving Services for the AOL Network under the
     License Agreement. IMGIS shall access such Demographic Data following the
     Commencement Date for the sole purpose of serving Targeted interactive

     whole or in part, whether in IMGIS' data center, on any user's hard drive
     or other component of such user's computer system, or in any other location
     or for any purpose. IMGIS shall not recreate, reproduce, compile, store or
     retain any information on any AOL User's hard drive or other component of
     such AOL User's computer system which would enable IMGIS to associate such
     AOL User with Demographic Data or to identify such AOL User using
     Demographic Data or any other data or information available to IMGIS. In no
     event shall IMGIS take any action that would enable IMGIS to identify an
     AOL User using Demographic Data or any other data or information available
     to IMGIS, and the Parties agree that any taking by IMGIS of such an action
     or any attempt by IMGIS to identify, or identification by IMGIS of, any AOL
     User using Demographic Data or other data or information available to IMGIS
     would constitute a breach by IMGIS of a material obligation hereunder.

          (d) To the extent that IMGIS is not prohibited hereunder from
     recreating, reproducing, compiling, storing or retaining any information on
     any AOL User's hard drive or other component of such AOL User's computer
     system, IMGIS shall do so in compliance with generally accepted standards
     for the protection of individual privacy rights as adopted by TRUSTe or
     another organization mutually agreeable to the Parties that is similarly
     dedicated to protecting the privacy rights of individuals who receive
     interactive advertisements; provided, however, that in no event shall the
     taking of any such action enable IMGIS to identify such AOL User.

of this Agreement, the Parties shall commence discussions on the preparation of
the Implementation Schedule and shall endeavor to reach agreement on a
preliminary Implementation Schedule within 60 days following the commencement of
such discussions. The final Implementation Schedule shall be agreed upon by the
Parties, and attached as an Exhibit hereto, within 30 days following the date as
of which the following conditions precedent are satisfied:

          (a)  The mutual determination by the Parties that there is general
               acceptance of Targeted interactive advertising, as conducted by
               IMGIS and as contemplated hereunder, in the marketplace of users
               of the Internet and online services, unless satisfaction of this
               condition precedent is waived by AOL in its sole discretion; and

          (b)  Following the mutual determination described in subpart (a) above
               or the waiver of such condition precedent by AOL, the receipt by
               AOL of any and all Third Party consents required for the
               Provision of Demographic Data to IMGIS, unless satisfaction of
               this condition precedent is waived by AOL in its sole discretion,
               in which case the Demographic Data to be Provided pursuant to the
               Implementation Schedule shall be adjusted accordingly.

     AOL shall deliver promptly to IMGIS a written notice informing IMGIS
     of the satisfaction or waiver of the foregoing conditions precedent. In no
     event shall the failure of AOL to deliver such a written notice to IMGIS be
     deemed to be a waiver by AOL of the foregoing conditions precedent. For
     purposes of this Agreement, the date as of which the Parties reach
     agreement on the final Implementation Schedule shall be referred to as the
     "Commencement Date".

     2.4  NO INDIVIDUAL IDENTIFICATION INFORMATION.

     (a) Notwithstanding the categories of Demographic Data set forth in Section
2.3 above, in no event shall AOL Provide Demographic Data to IMGIS in such
groups or combinations of categories that might enable IMGIS to identify the
particular AOL User having the characteristics expressed in such Demographic
Data. To this end, in the event that at any time there is no more than a Floor
Number of AOL Users (as defined below) in any group or combination of categories
of Demographic Data to be provided to IMGIS, then AOL shall have the right to
reduce the number of categories of Demographic Data in such group or
combination, or to aggregate Demographic Data within such group or combination,
to the extent necessary to increase the number of AOL Users in such group or
combination to a number above the Floor Number or, if this is not possible, then
AOL shall have the right to eliminate such group or combination of categories of
Demographic Data in its entirety.

     (b) If AOL takes any of the actions provided for in Section 2.4(a) above,
in no event shall the taking of such action mean, or be construed to mean, that
AOL is Materially Limiting or Prohibiting the use by IMGIS of Demographic Data
or be counted along with any other actions toward a determination that AOL is
Materially Limiting or Prohibiting the use by IMGIS of Demographic Data.

     (c) For purposes of this Agreement, "Floor Number" means the floor number
of AOL Users to be agreed upon by the Parties prior to the Commencement Date,
which number may be modified from time to time by mutual agreement of the
Parties.

             LIMITATIONS OR PROHIBITIONS ON USE OF DEMOGRAPHIC DATA

     3.1  SPECIFIC INTERACTIVE SITES AND SPECIFIC ADVERTISERS.

     (a) Notwithstanding any provision to the contrary herein, IMGIS shall not
use Demographic Data for the purpose of serving Targeted interactive
advertisements for or on behalf of:

               (i)  Any interactive sites or advertisers that are engaged in the
                    business of pornography or any other business of
                    questionable morality;

                                                                    CONFIDENTIAL

               (ii) Any interactive sites or advertisers whose sites or
                    advertising would violate AOL's Terms of Service as then in
                    effect as they apply to the distribution of content,
                    advertising and direct marketing and/or the principles
                    underlying such Terms of Service as they apply to the
                    foregoing; or

              (iii) Any one or more of the specific interactive sites and
                    specific advertisers to be listed on Schedule 3.1 attached
                    hereto, which Schedule shall be provided by AOL to IMGIS on
                    or prior to the Commencement Date and which may be modified
                    from time to time by AOL.

     (b) In the event that IMGIS notifies AOL that the aggregate of the dollars
received by the specific interactive sites, and the aggregate of the dollars
spent on interactive advertising by the specific advertisers, listed on Schedule
3.1 in the then most recent calendar quarter exceeds twenty-five percent (25%)
of the sum of (i) the available advertising dollars on the Internet and online
interactive services received by interactive sites in such calendar quarter and
(ii) the available advertising dollars on the Internet and online interactive
services spent by advertisers in such calendar quarter, in each case as reported
by Jupiter's WebTrack (or by any other publication that compiles such
information which is mutually agreeable to the Parties), with adjustment for any
duplicate counting of such dollar amounts as necessary, then AOL shall have the
right to modify Schedule 3.1 so that such 25% threshold is not exceeded and, in
the event that AOL does not modify Schedule 3.1 within ten business days of
receiving such notification from IMGIS, then, for so long as such 25% threshold
is exceeded:

               (i)  If such 25% threshold is exceeded by no more than ten
                    percentage points (i.e., is no more than 35%), IMGIS'
                    obligation to guarantee payment to AOL of any Minimum Annual
                    Fees shall be reduced by the percentage equal to the
                    following: (X - 25) divided by 75, where X equals the
                    percentage of the available advertising dollars on the
                    Internet and online interactive services received by the
                    specific interactive sites, and spent by the specific
                    advertisers, listed on Schedule 3.1; or

               (ii) If such 25% threshold is exceeded by more than ten
                    percentage points (i.e., is more than 35%), IMGIS shall not
                    be obligated to guarantee payment to AOL of any Minimum
                    Annual Fees.

     3.2 RIGHTS OF AOL. AOL shall have the right to immediately terminate or
defer IMGIS' access to any or all categories of Demographic Data or to
immediately limit or prohibit the use by IMGIS of any or all categories of
Demographic Data: (a) in the event that AOL receives any adverse publicity, is
subject to any law or issued or pending governmental regulation, or is the
subject of any pending or threatened governmental

                                                                    CONFIDENTIAL

investigation or legal action, regarding the use or provision of Demographic
Data or similar demographic information or which otherwise would limit or
prohibit Targeted interactive advertising; or (b) based on AOL policy, as such
policy may be modified from time to time in AOL's sole discretion, regarding
Targeted interactive advertising or the provision of Demographic Data or similar
demographic information. Immediately upon the receipt of notice from AOL that
AOL is exercising the foregoing right, IMGIS shall limit or terminate the use of
such categories of Demographic Data as indicated by AOL in such notice;
provided, however, that AOL shall consult with IMGIS prior to any decision that
would materially affect IMGIS' access to Demographic Data. In any event where
IMGIS is limited or prohibited from the use of any or all categories of
Demographic Data, AOL shall be limited or prohibited during the term of this
Agreement from providing any Third Party with access to such Demographic Data or
similar demographic information for the purpose of serving Targeted interactive
advertisements.

     3.3 DEFINITION OF "MATERIALLY LIMIT OR PROHIBIT". If AOL takes any action
(other than action permitted under Section 2.4 above) that would terminate or
prohibit IMGIS' access to all categories of Demographic Data with respect to
more than fifty percent (50%) of AOL Users, excluding children and other
individuals to whom Targeted interactive advertising may be at such time legally
prohibited, for more than a period of 30 cumulative days in any calendar year,
then, beginning 120 days from the date that AOL restricts IMGIS from such use,
AOL shall be deemed to "Materially Limit or Prohibit" the use by IMGIS of
Demographic Data for purposes of this Agreement. IMGIS agrees that, in the event
that AOL Materially Limits or Prohibits the use by IMGIS of Demographic Data,
such action shall in no event constitute, or be deemed to constitute, a breach
by AOL of, or failure by AOL to perform, an obligation under this Agreement or
under the License Agreement.

                                PAYMENTS BY IMGIS

     4.1 FEES. For all Targeted interactive advertisements served by or on
behalf of IMGIS using the IMGIS AdForce System to AOL Users for whom AOL has
Provided Demographic Data, IMGIS shall pay to AOL, on a quarterly basis, a fee
per advertisement equal to the greater of:

     (a)  5% of the gross amount of the consideration charged by IMGIS for
          serving such Targeted interactive advertisement (the "Gross Amount");
          and

     (b)  35% of the difference between (i) the gross amount of the
          consideration charged by IMGIS for serving such Targeted interactive
          advertisement and (ii) the gross amount of the consideration that
          would have been charged by IMGIS for serving a comparable interactive
          advertisement using the IMGIS AdForce

<PAGE>

                                                                    CONFIDENTIAL

          System where such interactive advertisement is not Targeted (the
          "Incremental Revenue Amount");

Provided, however, that, for all such Targeted interactive advertisements served
by or on behalf of IMGIS using the IMGIS AdForce System during the first twelve
months following the Year One Start Date (as defined below), IMGIS shall pay to
AOL a fee per advertisement equal to the greater of (x) 10% of the Gross Amount
of such advertisement and (y) 70% of the Incremental Revenue Amount of such
advertisement, until such time as AOL has received fees equal to $5 million in
the aggregate.

     4.2 FEES IN EVENT OF NONMONETARY OR DISCOUNTED CONSIDERATION. In the event
that, in any calendar quarter, IMGIS serves Targeted interactive advertisements
using the IMGIS AdForce System to AOL Users for whom AOL has Provided
Demographic Data in exchange for nonmonetary consideration or any combination of
monetary and nonmonetary consideration, for any consideration below the fair
market value of such interactive ad serving services, or for no consideration at
all, then IMGIS shall pay to AOL the fee required under Section 4.1 above for
each such advertisement based on the gross amount of the fair market value of
such interactive ad serving services but in no event shall such payment to AOL
be less than the largest payment paid by IMGIS to AOL under Section 4.1 during
such quarter. Nothing herein shall limit IMGIS' discretion to grant commercially
reasonable discounts.

     4.3 GUARANTEED MINIMUM ANNUAL FEES. So long as AOL is in compliance with
all of its material obligations under this Agreement and does not Materially
Limit or Prohibit the use by IMGIS of Demographic Data, IMGIS shall guarantee to
AOL the payment of the following Minimum Annual Fees payable on a quarterly
basis (each such payment being a "Quarterly Portion" of the then applicable
Minimum Annual Fee) for Targeted interactive advertisements served by or on
behalf of IMGIS using the IMGIS AdForce System to AOL Users for whom AOL has
Provided Demographic Data:

          (a)  For all such Targeted interactive advertisements served during
               the twelve month period following the Commencement Date, unless
               AOL does not Provide Demographic Data to IMGIS within 60 days
               following the Commencement Date, in which case such date shall be
               the date as of which AOL first Provides Demographic Data to IMGIS
               (such date to be referred to as the "Year One Start Date" and
               such twelve month period to be referred to as "Year One"):

               $4 million;

          (b)  For all such Targeted interactive advertisements served during
               the twelve month period following the first anniversary of the
               Year One Start Date ("Year Two"):

               The greater of (i) $3 million and (ii) one-half of the aggregate
               amount of fees payable by IMGIS to AOL for Year One (including

                                       10
<PAGE>

                                                                    CONFIDENTIAL

               any amount payable by IMGIS to meet the Minimum Annual Fee for
               Year One) (such greater amount to be referred to hereafter as the
               "Year Two Minimum"); and

          (c)  For all such Targeted interactive advertisements served during
               the twelve month period following the second anniversary of the
               Year One Start Date ("Year Three"):

               The greater of (i) the Year Two Minimum and (ii) one-half of the
               aggregate amount of fees payable by IMGIS to AOL for Year Two
               (including any amount payable by IMGIS to meet the Minimum Annual
               Fee for Year Two);

Provided, however, that, in the event that, at any time during the term of this
Agreement, AOL provides access to Demographic Data to an IMGIS Competitor for
the purpose of serving Targeted interactive advertisements, then the Quarterly
Portion of the Minimum Annual Fee payable by IMGIS at the end of the calendar
quarter in which such event occurs shall be reduced ratably by the number of
days in such quarter during which AOL provides Demographic Data to such IMGIS
Competitor and IMGIS shall not be obligated to guarantee payment to AOL of any
Minimum Annual Fees thereafter.

In the event that, in Year One or Year Two (or in Year Three if this Agreement
is renewed and requires IMGIS to guarantee payment of a minimum annual fee
during such renewal term), IMGIS makes a payment to AOL in excess of the amount
of fees due under Section 4.1 in satisfaction of IMGIS' obligation under this
Section 4.3 to guarantee payment of the Minimum Annual Fee for such year (the
"Excess Amount"), then IMGIS may recoup such Excess Amount in any subsequent
year in which the Agreement remains in effect, including any renewal term, by
crediting such Excess Amount against the fees due to AOL in such subsequent year
following the payment to AOL in such subsequent year of the Minimum Annual Fee
due to AOL for such year and only to the extent that the amount of fees due to
AOL in such subsequent year exceeds the Minimum Annual Fee for such year.

     4.4 PAYMENT PROCEDURES.

     (a) IMGIS shall pay to AOL all fees and other amounts due and owing to AOL
as described herein for the serving of Targeted interactive advertisements
within 60 days of the end of the calendar quarter in which such Targeted
interactive advertisements are served using the IMGIS AdForce System, together
with a written report (in addition to the report required under Section 2.1(a)
above) signed by an officer of IMGIS setting forth the number of Targeted
interactive advertisements served during such calendar quarter, the Gross Amount
of each such Targeted interactive advertisement, and the Incremental Revenue
Amount of each such Targeted interactive advertisement.

                                                                    CONFIDENTIAL

     (b) All payments due to AOL hereunder shall be paid to AOL in U.S. Dollars
by wire transfer, or by such other method mutually agreed upon by the Parties,
in each case at the expense of IMGIS, for value no later than the due date
thereof (with 24 hours advance notice of each wire transfer) to such bank
account or accounts as AOL shall designate in writing within a reasonable period
of time prior to such due date.

     4.5 LATE PAYMENT. Without limiting AOL's rights to pursue any other
remedies at law or in equity, if IMGIS fails to pay any payment required under
this Agreement on or before the due date therefor, then IMGIS shall pay annually
compounded interest on such amount at an annual rate equal to the lower of (a)
the highest rate permitted by applicable law and (b) the lowest prime rate as
published by The Wall Street Journal on or nearest to such due date plus three
percent (3%), which interest shall accrue from the date the payment not timely
made became due until the date such payment is paid in full.

     4.6 APPLICATION OF PAYMENTS. Any payments received by AOL shall be applied
first to the satisfaction of the oldest of any unpaid, accrued interest charges
and, following payment of all such interest charges, to the satisfaction of the
oldest of any unpaid fees or other amounts due hereunder.

     4.7 TAXES. All payments required to be made by IMGIS under this Agreement
shall be made free and clear of, and without deduction for, any and all taxes
that are levied on the transfer of such payments to AOL. If any withholding or
deductions are required by applicable law, payments shall be made such that,
after such withholding or deductions, the net amount that AOL receives is equal
to the amount due under this Article 4. IMGIS shall file any information or tax
returns with respect to such taxes, and IMGIS shall indemnify AOL from any
interest or other payments, fines or penalties relating to or resulting from any
failure, delay or error of IMGIS in doing so.

     4.8 NO DIVERSION. IMGIS agrees that it shall not knowingly engage in any
action or practice that results in reducing any fees or other payment
obligations under this Article 4 that otherwise would have been owed to AOL
hereunder as consideration for the Provision of Demographic Data to IMGIS.

     4.9 BOOKS AND RECORDS. IMGIS shall keep full, true and accurate books of
account containing all particulars and reasonable supporting documentation that
may be necessary for the purpose of determining the fees and other amounts
payable to AOL hereunder and IMGIS' compliance in other respects with its
obligations under this Agreement, including, without limitation, its obligations
under Section 2.1 above. All such books of account and reasonable supporting
documentation shall be located at the principal place of business of IMGIS and
shall be open for inspection for such purpose by AOL or any independent
certified public accountant retained by AOL, at a time mutually acceptable to
AOL and IMGIS during normal business hours but no more frequently than once each
calendar year for three years following the end of the calendar year to which
they pertain (and access shall not be denied thereafter if reasonably
available). If such records are insufficient for the foregoing purposes or any
such inspection discloses an underpayment to AOL of five percent (5%) or more of
the amount actually due for any 

                                       12

quarterly period, then, in addition to any other rights and remedies available
to AOL under this Agreement, IMGIS shall pay to AOL the amount of such
underpayment as well as the reasonable cost of such inspection promptly
following IMGIS' receipt from AOL of the bill or invoice for such inspection.

                                 INDEMNIFICATION

     5.1 INDEMNITY BY IMGIS. AOL shall not be liable to IMGIS, any of its
Affiliates or any other Person for, and IMGIS shall indemnify and hold harmless
AOL and all AOL Affiliates, and their respective directors, officers, employees
and agents (collectively, the "AOL Indemnitees"), from and against any Losses
incurred arising out of or resulting from the serving of Targeted interactive
advertisements using the IMGIS AdForce System or otherwise from the use of
Demographic Data by IMGIS or any of its Affiliates, except to the extent that
such Losses arise out of or result from the provision by AOL of Demographic Data
that AOL is not permitted to provide to IMGIS.

     5.2 INDEMNITY BY AOL. IMGIS shall not be liable to AOL, any of its
Affiliates or any other Person for, and AOL shall indemnify and hold harmless
IMGIS and its Affiliates, and their respective directors, officers, employees
and agents (collectively, the "IMGIS Indemnitees"), from and against any Losses
incurred arising out of or resulting from the provision by AOL of Demographic
Data that AOL is not permitted to provide to IMGIS, except to the extent that
such Losses arise out of or result from the use of Demographic Data that AOL is
permitted to provide by IMGIS or any of its Affiliates.

     5.3 PROCEDURE. Any AOL Indemnitee or IMGIS Indemnitee shall notify IMGIS or
AOL, as the case may be (the "Indemnifying Party"), promptly in writing of an
indemnifiable claim or cause of action under Section 5.1 or Section 5.2 above
upon receiving notice or being informed of the existence thereof; provided,
however, that failure to notify the Indemnifying Party of an indemnifiable claim
or cause of action shall not relieve the Indemnifying Party of its obligation to
provide indemnification hereunder, except to the extent that such failure
prejudices the Indemnifying Party's ability to defend or settle such claim or
cause of action. The Indemnifying Party shall assume, at its cost and expense,
the sole defense of such claim or cause of action through counsel selected by
the Indemnifying Party and reasonably acceptable to the other Party, except that
in the case of a conflict of interest between the Indemnifying Party and the
other Party, the Indemnifying Party shall, at its cost and expense, provide
separate counsel for the other Party selected by the other Party. The
Indemnifying Party shall maintain control of such defense, including any
decision as to settlement; provided that, in the event that the Indemnifying
Party does not maintain control of such defense on a timely basis, then, without
prejudice to any other rights and remedies available to the other Party under
this Agreement, the other Party may take over such defense with counsel of its
choosing, at the Indemnifying Party's cost and expense. The other Party may, at
its option and expense, participate in the Indemnifying Party's defense, and if
the other Party so participates, the

Parties shall cooperate with one another in such defense. The Indemnifying Party
shall bear the total costs of any court award or any settlement of such claim or
cause of action approved by the Indemnifying Party and all other costs, fees and
expenses related to the resolution thereof (including reasonable attorneys'
fees, except for attorneys' fees for which the other Party is responsible in the
event that the other Party participates in the Indemnifying Party's defense of
such claim or cause of action).

               enforceability is considered in a proceeding at law or in equity)
               and the effect of applicable bankruptcy, insolvency, moratorium
               and other similar laws of general application relating to or

EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS ARTICLE 7, NEITHER PARTY MAKES
ANY OTHER WARRANTY OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, AND ALL IMPLIED
WARRANTIES, INCLUDING THE WARRANTY OF FITNESS FOR A PARTICULAR USE OR PURPOSE

EXCLUDED FROM THIS AGREEMENT.


                                   ARTICLE 8
                                 CONFIDENTIALITY

     8.1 CONFIDENTIALITY OBLIGATION. Each of AOL and IMGIS (the "Receiving
Party") shall keep, and shall cause their Affiliates to keep, strictly
confidential any information disclosed by the other Party (the "Disclosing
Party") or otherwise made available to the Receiving Party concerning the
Demographic Data to be provided hereunder or either Party's performance of this
Agreement or otherwise concerning 

                                       15

                                                                    CONFIDENTIAL

the business, operations, trade secrets or other proprietary information of the
Disclosing Party (whether in written media or otherwise) ("Confidential
Information"), using at least the same degree of care that it uses to protect
its own confidential or proprietary information. "Confidential Information"
shall not include information: (a) which is or becomes generally available to
the public other than as a result of disclosure thereof by the Receiving Party;
(b) which is lawfully received by the Receiving Party on a nonconfidential basis
from a Third Party that is not itself under any obligation of confidentiality or
nondisclosure to the Disclosing Party or any other Person with respect to such
information; or (c) which is independently developed by the Receiving Party.

     8.2 NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Receiving Party shall
use Confidential Information solely for the purposes of this Agreement and the
transactions contemplated hereby and shall not disclose or disseminate any
Confidential Information to any Person at any time, except for disclosure to its
Affiliates and to those of its own and its Affiliates' directors, officers,
employees, accountants, attorneys, advisers and agents whose duties reasonably
require them to have access to such Confidential Information, provided that such
directors, officers, employees, accountants, attorneys, advisers and agents are
bound to maintain the confidentiality of such Confidential Information to the
same extent as if they were Parties hereto.

     8.3 EXCEPTION. The foregoing confidentiality and nondisclosure obligations
shall not apply to Confidential Information which is required to be publicly
disclosed by law or by regulation; provided, however, that, in such event, the
Receiving Party provides the Disclosing Party with prompt advance notice of such
disclosure so that the Disclosing Party has the opportunity if it so desires to
seek a protective order or other appropriate remedy.

     8.4 SURVIVAL. The confidentiality and nondisclosure obligations of this
Article 8 shall survive the expiration or termination of this Agreement.



                                   ARTICLE 9
                              TERM AND TERMINATION

     9.1 TERM. This Agreement shall commence as of the date hereof and, unless
otherwise terminated in accordance with Section 9.2 or 9.3 below, shall remain
in full force and effect for the earlier of: (a) three years following the Year
One Start Date; and (b) four years following the date hereof. Thereafter, this
Agreement may be renewed on a year-to-year basis at the option of AOL on the
same terms, except that the Parties shall negotiate mutually acceptable minimum
annual fees to be payable by IMGIS in consideration for Targeted interactive
advertisements served during such renewal period by or on behalf of IMGIS using
the IMGIS AdForce System to AOL Users for whom AOL has Provided Demographic
Data. In the event that AOL desires to exercise this option, AOL shall notify
IMGIS in writing of its desire to renew this Agreement at least 90 days prior to
the end of the initial term of this Agreement or any renewal term thereof.

     9.2 TERMINATION RIGHTS OF EITHER PARTY. Either Party shall have the right
to terminate this Agreement in the event of the breach by the other Party of, or
the failure of the other Party to perform, any of its material obligations
hereunder and the failure to remedy such breach or nonperformance within 60 days
following the receipt of written notice of such breach or nonperformance from
the nonbreaching Party. Such termination shall be immediately effective upon the
receipt by the breaching or nonperforming Party of written notice of termination
from the nonbreaching Party.

     9.3 ADDITIONAL TERMINATION RIGHTS OF AOL.

          (a) In addition to the right of termination provided in Section 9.2
     above, AOL shall have the right to terminate this Agreement, at any time
     following the earlier of (i) the first anniversary of the Year One Start
     Date and (ii) the second anniversary of the date hereof, in the event that
     AOL has received an offer from a Third Party seeking access to Demographic
     Data on terms that are, and for financial consideration that is, more
     favorable than the terms and financial consideration provided by IMGIS to
     AOL in this Agreement and, within ten business days after the receipt from
     AOL of notice of such Third Party offer, IMGIS has refused to modify this
     Agreement to match the terms and financial consideration of such Third
     Party offer or has failed to respond to the AOL notice. Such termination
     shall be immediately effective upon the receipt by IMGIS of written notice
     of termination from AOL and the receipt by IMGIS of: (i) $12,000,000, in
     the event that the termination notice is delivered by AOL to IMGIS at any
     time during Year Two or, if the second anniversary of the date hereof
     occurs earlier than the first anniversary of the Year One Start Date,
     during the twelve month period following the second anniversary of the date
     hereof; or (ii) $6,000,000, in the event that the termination notice is
     delivered by AOL to IMGIS at any time during Year Three or, if the second
     anniversary of the date hereof occurs earlier than the first anniversary of
     the Year One Start Date, during the twelve month period following the third
     anniversary of the date hereof.

          (b) In addition to the right of termination provided in Section 9.2
     above, AOL shall have the right to terminate this Agreement in the event of
     a "License Agreement Material Breach" by IMGIS. For purposes of this
     Agreement, a "License Agreement Material Breach" means the breach by IMGIS
     of, or the failure of IMGIS to perform, any of its material obligations
     under the License Agreement, the failure of IMGIS to remedy such breach or
     nonperformance within 60 days following the receipt of written notice of
     such breach or nonperformance from AOL, and, in the event that such breach
     or nonperformance is disputed by the Parties, the final determination of
     such breach or nonperformance by a court of competent jurisdiction from
     which no further appeal may be taken. Such termination shall be immediately
     effective upon the receipt by IMGIS of written notice of termination from
     AOL.

     9.4 SURVIVAL. All rights granted to and obligations undertaken by the
Parties hereunder shall terminate immediately upon the expiration or termination
of this Agreement except for the following, which shall survive according to
their terms:

          (a)  The obligations of IMGIS under Section 2.1(c);

          (b)  The obligation of IMGIS to pay to AOL any and all fees and other
               payments accrued under Article 4;

               provided in Section 4.9;

          (d)  The indemnification obligations of Article 5 and the limitation
               on liability of Article 6;

          (e)  The confidentiality and nondisclosure obligations of Article 8;
               and

          (f)  The provisions of Sections 10.2, 10.3, 10.5, 10.14 and 10.15
               below.

In addition, expiration or termination of this Agreement shall not affect the
remedies of the Parties otherwise available at law or in equity in relation to
any rights accrued under this Agreement prior to expiration or termination.



                                   ARTICLE 10
                                  MISCELLANEOUS

             Attention:      Gordon K. Davidson

     10.6 FORCE MAJEURE. If any circumstance beyond the reasonable control of
either Party occurs which delays or renders impossible the performance of that
Party's obligations under this Agreement on the dates herein provided, such
obligation shall be postponed for such time as such performance necessarily has
had to be suspended or delayed on account thereof, provided such Party shall
notify the other Party in writing as soon as practicable, but in no event more
than ten days after the occurrence of such force majeure. In such event, the
Parties shall meet promptly to determine an equitable solution to the effects of
any such event, provided that such Party who fails because of force majeure to
perform its obligations hereunder shall upon the cessation of the force majeure
take all reasonable steps within its power to resume with the least possible
delay compliance with its obligations. Events of force majeure shall include,
without limitation, war, revolution, invasion, insurrection, riots, mob
violence, sabotage or other civil disorders, acts of God, limitations imposed by
exchange control regulations or foreign investment regulations or similar
regulations, laws, regulations or rules of any government or governmental
agency, and any inordinate and unanticipated delays in the regulatory review or
governmental approval process that are within the control of such government or
governmental agency.

     10.7 BINDING EFFECT; ASSIGNMENT. This Agreement may not be assigned, in
whole or in part, by either Party without the prior written consent of the other
Party, and any attempted assignment without such consent shall be null and void.
An assignment of this Agreement requiring the consent of the other Party shall
include, without limitation: (i) the acquisition by a Third Party of more than
fifty percent (50%) of the voting power of the assigning Party; (ii) the
acquisition by a Third Party of all or substantially all of the assets of the
assigning Party; and (iii) the consummation of a merger, consolidation or
similar corporate transaction of the assigning Party with or into a Third Party
where the voting securities of the assigning Party outstanding immediately prior
to consummation of such transaction are converted into cash or securities
possessing less than fifty percent (50%) of the voting power of the surviving
entity; provided, however, that such consent shall not be unreasonably withheld
and provided, further, that IMGIS agrees, by way of example, that, if AOL is the
other Party whose consent is being sought, it shall not be unreasonable for AOL
to withhold its consent if the Third Party is a competitor of AOL (e.g., if the
Third Party engages in a business that competes with the AOL Network) or if the
Third Party is engaged in the business of pornography or any other business of
questionable morality. Any assignment by IMGIS in violation of this Section 10.7
shall constitute a breach by IMGIS of a material obligation hereunder for which
AOL shall have the right, notwithstanding the provisions of Section 9.2 above,
to immediately terminate this Agreement without allowance of any period to
remedy such breach, such termination

                                       20

                                                                    CONFIDENTIAL

to be immediately effective upon the receipt by IMGIS of written notice of
termination from AOL; provided, however, that in the event that any such
assignment occurs as the result of the consummation of a merger, consolidation
or similar corporate transaction as described in subpart (iii) above, then AOL's
sole remedy in such event shall be such right of termination. This Agreement
shall inure to the benefit of and be binding upon each of the Parties hereto and
their respective successors and permitted assigns.

     10.8 ENTIRE AGREEMENT. The terms and conditions herein contained constitute
the entire agreement between the Parties relating to the subject matter of this
Agreement and shall supersede all previous communications between the Parties
with respect to the subject matter of this Agreement, except for the Letter
Agreement between the Parties dated as of April 14, 1998 and the Confidential
Non-Disclosure Agreement between the Parties dated as of April 15, 1998, each of
which shall survive according to their terms. Neither Party has entered into
this Agreement in reliance upon any representation, warranty, covenant or
undertaking of the other Party that is not set out or referred to in this
Agreement.

     10.9 RECITALS, SCHEDULES AND EXHIBIT. The recitals set forth at the start
of this Agreement along with the Schedule attached, and the Schedule and Exhibit
to be attached, to this Agreement and the terms and conditions incorporated in
such recitals, Schedules and Exhibit shall be deemed integral parts of this
Agreement, and all references in this Agreement to this Agreement shall
encompass such recitals, Schedules and Exhibit and the terms and conditions
incorporated in such recitals, Schedules and Exhibit.

     10.10 AMENDMENT. This Agreement may be varied, amended or extended only by
the written agreement of the Parties through their duly authorized officers or
representatives, specifically referring to this Agreement.

     10.11 SEVERABILITY. In the event that any provision of this Agreement is
held to be illegal, invalid or unenforceable in a final, unappealable order or
judgment (each such provision, an "invalid provision"), then such provision
shall be severed from this Agreement and shall be inoperative, and the Parties
promptly shall negotiate in good faith a lawful, valid and enforceable provision
that is as similar to the invalid provision as may be possible, while the
remaining provisions of this Agreement shall remain binding on the Parties
hereto.

     10.12 HEADINGS. The descriptive headings of the several articles and
sections of this Agreement are inserted for convenience only and do not
constitute a part of this Agreement.

     10.13 NO WAIVER OF RIGHTS. No failure or delay on the part of either Party
in the exercise of any power or right hereunder shall operate as a waiver
thereof. No single or partial exercise of any right or power hereunder shall
operate as a waiver of such right or of any other right or power. The waiver by
either Party of a breach of any provision of this Agreement shall not operate or
be construed as a waiver of any other or subsequent breach hereunder.

                                                                    CONFIDENTIAL

     10.14 REMEDIES CUMULATIVE; SPECIFIC PERFORMANCE. All rights and remedies
granted to either Party under this Agreement are cumulative and in addition to,
and not in lieu of, any other rights or remedies otherwise available to such
Party at law or in equity. The Parties agree that any breach by either Party of,
or failure of either Party to perform, any obligation under this Agreement shall
constitute immediate and irreparable damage to the other Party which cannot be
fully and adequately compensated in money damages and that, in the event of such
breach or failure, the other Party shall be entitled to injunctive relief and
specific performance in addition to any other remedies to which it may be
entitled at law or in equity.

     10.15 CONFIDENTIALITY OF AGREEMENT. Each Party shall maintain the
confidentiality of this Agreement and all provisions of this Agreement and,
without the prior consent of the other Party, neither Party shall make any press
release or other public announcement of or otherwise disclose this Agreement or
any of its provisions to any Third Party (a) other than to its Affiliates and to
its own and its Affiliates' directors, officers, employees, attorneys and
accountants, and to the lead underwriter engaged by IMGIS in connection with any
offering of securities of IMGIS, whose duties reasonably require familiarity
with this Agreement, provided that such Persons (including any such lead
underwriter) are bound to maintain the confidentiality of this Agreement, and
(b) except for such disclosure as may be required by applicable law or
regulation, in which case the disclosing Party shall provide the other Party
with prompt advance notice of such disclosure so that the other Party has the
opportunity if it so desires to seek a protective order or other appropriate
remedy; provided that, in connection with any offering of securities of IMGIS,
IMGIS shall provide in advance to AOL for review the form and content of any
disclosure of this Agreement or any of its provisions that may be required by
applicable law or regulation and, to the extent consistent with its disclosure
obligations under applicable law, include such modifications to such disclosure
as may be reasonably requested by AOL (except that IMGIS may file this Agreement
as an exhibit to its registration statement if it would constitute a "material
agreement" under applicable law or regulation and IMGIS shall use its reasonable
best efforts to obtain confidential treatment of the portions of this Agreement
that meet the SEC qualifications for confidential treatment if so requested by
AOL). The confidentiality obligations of this Section 10.15 would apply, inter
alia, to any disclosure by IMGIS of this Agreement or of any provisions of this
Agreement to any customer or potential customer of IMGIS and any such disclosure
would constitute a breach of this Section 10.15. The Parties agree that any
breach of the provisions of this Section 10.15 by either Party, including,
without limitation, by any directors, officers or employees of such Party, would
constitute a breach by such Party of a material obligation hereunder for which
the other Party shall have the right, notwithstanding the provisions of Section
9.2 above, to immediately terminate this Agreement without allowance of any
period to remedy such breach, such termination to be immediately effective upon
the receipt by the breaching Party of written notice of termination from the
nonbreaching Party.

     10.16 USAGE. Wherever any provision of this Agreement uses the term
"including" (or "includes"), such term shall be deemed to mean "including
without limitation" and "including but not limited to" (or "includes without
limitation" 

                                       22

and "includes but is not limited to") regardless of whether the words "without
limitation" or "but not limited to" actually follow the term "including" (or
"includes").

     2.1 LICENSE GRANT.


          (a) Subject to the terms and conditions hereof, IMGIS hereby grants to
AOL a perpetual, worldwide, nonexclusive, nontransferable (except as set forth
in Section 15.12 below), royalty-free license under all of IMGIS' patent,
copyright, trade secret and other proprietary rights to use, reproduce, adapt,
transmit, perform, display and otherwise practice the Technology or any part
thereof, other than commercially available Third Party software that IMGIS has
the right to provide to AOL only upon payment of a fee to the Third Party,
solely for the Permitted Purposes and to sublicense such rights to AOL
Affiliates solely for the Permitted Purposes.

          (b) If any Technology consists of commercially available Third Party
software that IMGIS has the right to provide to AOL only upon payment of a fee
to the Third Party, AOL may, by written notice to IMGIS and payment of such fee,
require IMGIS to grant to AOL a perpetual, worldwide, nonexclusive,
nontransferable (except as set forth in Section 15.12 below), royalty-free
(except for such fee) license under all applicable patent, copyright, trade
secret and other proprietary rights to use, reproduce, adapt, transmit, perform,
display and otherwise practice such Technology or any part thereof solely for
the Permitted Purposes and to sublicense such rights to AOL Affiliates solely
for the Permitted Purposes (but only to the extent of IMGIS' rights in such
Technology).

          (c) In the event that AOL grants a sublicense to an AOL Affiliate
under any of the licenses granted in Section 2.1(a) or (b) above, AOL shall
enter into a sublicense agreement with such AOL Affiliate in a form to be
approved by IMGIS, which approval shall not be unreasonably withheld, and
included in such sublicense shall be the agreement of such AOL Affiliate to be
bound by the terms of this Agreement. AOL shall notify IMGIS of the grant of any
sublicense to an AOL Affiliate.

          (d) AOL shall not disclose or transfer the source code for any
Software included in the Technology to any AOL Affiliate that is not a
wholly-owned subsidiary of AOL. If IMGIS includes trademark or other proprietary
rights notices on copies of the Technology delivered to AOL, AOL shall reproduce
such notices on copies of the Technology made by AOL.

          (e) The Parties agree that neither the licenses granted in this
Section 2.1 nor any other provisions of this Agreement impose or shall be
construed to impose any obligation upon AOL to use or otherwise practice the
Technology. IMGIS agrees that it shall not bring any action in law or equity, or
any other judicial or nonjudicial proceeding, against AOL asserting that the use
by AOL of any patent rights claiming the Technology that are now or hereafter
owned by or licensed to IMGIS or any other Technology infringes or otherwise
violates any patent, copyright, trade secret or other proprietary rights of
IMGIS.

     2.2 EXERCISE OF RIGHTS. AOL may exercise its rights in and to the
Technology at any location, on any hardware, and with respect to all, none or
any portion or combination of the Technology. Nothing in this Agreement shall

connection with such Technology.

     2.3 USE OF PERSONNEL. AOL may exercise its rights hereunder through
Personnel who are obligated by written agreement to maintain the Technology in
confidence and restrict their use of the Technology pursuant to terms comparable
to those set forth in Article 13.

     3.1 INITIAL DELIVERY. Within 45 days after the date hereof, IMGIS shall
deliver to AOL: (a) one machine-readable copy of the object code for the
Software; (b) one copy of available technical and user documentation for the
Technology in printed and machine-readable format as available; and (c) one
machine-readable copy of the source code for the Software. Such delivery shall
be transmitted electronically or by any other means agreed upon by IMGIS and
AOL.

     3.2 DELIVERY OF IMPROVEMENTS AND OTHER TECHNOLOGY.

          (a) IMGIS shall use commercially reasonable efforts regularly to
develop Improvements to adapt the Technology to changes in related technologies
and in market and user requirements and to remain competitive with alternative
technologies for the serving, trafficking and/or targeting of advertisements or
other information or materials.

          (b) At such times as reasonably requested by AOL, IMGIS shall provide
AOL with any Improvements made by or on behalf of IMGIS and any other Technology
requested by AOL that is existing and not then in the possession of AOL. In
addition, commencing no later than 45 days after such time that AOL determines
to deploy the Technology in whole or in part (the "Deployment Date"), IMGIS
shall provide to AOL on a quarterly basis the then current version of the source
code for the Software and shall provide to AOL any and all Improvements,
including upgrades, updates, enhancements, patches and "bug" fixes, prior to or
concurrently with their installation or release, by any means requested by AOL
(including electronically), along with the applicable documentation related to
such Improvement.

          (c) IMGIS shall provide all Improvements and other Technology, other
than Improvements provided in the provision of Development Services, to AOL
without any additional charge or fee provided that, in the case of any
Improvement, AOL is in compliance with all of its material obligations under the
Demographic Data Agreement and does not Materially Limit or Prohibit the use by
IMGIS of Demographic Data at the time such Improvement is developed. If AOL
ceases to be in compliance with all of its material obligations under the
Demographic Data Agreement or Materially Limits or Prohibits the use by IMGIS of
Demographic Data, and AOL desires to continue receiving Improvements from IMGIS,
then AOL shall pay to IMGIS on an annual basis a reasonable update fee to be
agreed upon by the Parties for all Improvements developed for so long as AOL is
not in compliance with all of its material obligations under the Demographic
Data Agreement or Materially Limits or Prohibits the use by IMGIS of Demographic
Data; provided that such fee shall not exceed (i) IMGIS' customary update fees
for such Improvements in arm's length transactions with its licensees, if IMGIS
then licenses the Technology to Third Parties, or (ii) update fees charged by
other licensors of comparable systems for serving, trafficking and/or targeting
of advertisements or other information or materials, but not less

than IMGIS' cost of providing such Improvements, if IMGIS does not then license
the Technology to Third Parties.

          (d) At AOL's request, IMGIS shall identify to AOL, and provide AOL
reasonable information and assistance in furtherance of AOL's efforts to
acquire, at AOL's own expense, commercially available Third Party software
licensed to IMGIS for use in connection with the Technology and not sublicensed
to AOL under Section 2.1(a) or (b) above.

     4.1 SCOPE OF SERVICES.

          (a) During the term of this Agreement, IMGIS shall provide to AOL, at
AOL's written request, reasonable technical training, support, documentation and
assistance relating to the interactive content (including interactive
advertisement) serving, trafficking, targeting and related functions of the
Technology (collectively, "Technical Support Services"). The Technical Support
Services shall, at a minimum, enable AOL, without the aid of IMGIS or any other
Person, to develop, enhance and maintain the Technology (including the source
code for the Software) for use by AOL to the same extent as IMGIS.

          (b) Commencing no later than 45 days after the Deployment Date, the
Technical Support Services shall include, without limitation: (i) the regular
provision by IMGIS of qualified Personnel able to resolve problems in the
operation of the Technology on-site at AOL's data centers in the greater
Washington metropolitan area; and (ii) the provision by IMGIS of telephone
access 24 hours a day, seven days a week, to qualified Personnel able to resolve
problems in the operation of the Technology, via a designated telephone support
number.

     4.2 FEES FOR TECHNICAL SERVICES SUPPORT.

          (a) Provided that, at the time any Technical Support Services are
requested by AOL or are to be performed by IMGIS, AOL is in compliance with all
of its material obligations under the Demographic Data Agreement and does not
Materially Limit or Prohibit the use by IMGIS of Demographic Data, IMGIS shall
provide the Technical Support Services requested by AOL for no additional
consideration other than reimbursement of the Fully Burdened Costs of the
provision by IMGIS Personnel of such Technical Support Services.

          (b) If, at the time any Technical Support Services are requested by
AOL or are to be performed by IMGIS: (i) the Implementation Date has not yet
occurred under the Demographic Data Agreement and no more than twelve months
have passed since the

execution of the Demographic Data Agreement, then AOL shall pay to IMGIS the 
Fully Burdened Costs of the provision by IMGIS Personnel of such Technical 
Support Services plus twenty-five percent (25%) of such costs; or (ii) the 
Implementation Date has not yet occurred under the Demographic Data Agreement 
and more than twelve months have passed since the execution of the 
Demographic Data Agreement, then AOL shall pay to IMGIS the Fully Burdened 
Costs of the provision by IMGIS Personnel of such Technical Support Services 
plus forty percent (40%) of such costs.

          (c) If, following the occurrence of the Implementation Date, at the
time any Technical Support Services are requested by AOL or are to be performed
by IMGIS, AOL is not in compliance with all of its material obligations under
the Demographic Data Agreement or Materially Limits or Prohibits the use by
IMGIS of Demographic Data, then AOL shall pay to IMGIS the Fully Burdened Costs
of the provision by IMGIS Personnel of such Technical Support Services plus
twenty-five percent (25%) of such costs.

     4.3 WARRANTY. In the event that the Technology fails to conform to or
perform in accordance with the technical or user documentation provided by IMGIS
(other than as a result of operator error, accident, or misuse or alteration of
the Technology by a Person not under IMGIS' direction or control) or in the
event of a breach of the warranties set forth in Section 10.2(e) or 10.2(f)
below, then IMGIS, at its expense and without any payment by AOL for Technical
Support or other Services, shall use commercially reasonable efforts to cure
such failure or breach as soon as practicable, but in any event:

          (a)  For a "critical" failure or breach, such as the Technology, or
               other software, hardware or other technology with which the
               Technology is interfacing or integrating, ceasing to execute a
               function that AOL reasonably deems critical to its business,
               IMGIS shall provide at least a temporary workaround or fix within
               two hours of receiving notice of such failure or breach and shall
               cure such failure or breach within three business days of
               receiving notice of such failure or breach; and

          (b)  For any other failure or breach that is not a "critical" problem,
               IMGIS shall provide at least a temporary workaround or fix within
               three business days of receiving notice of such failure or breach
               and shall cure such failure or breach within 15 days after
               receiving notice of such failure or breach.

Without limiting the generality of the foregoing, IMGIS agrees, by way of
example, that it shall not be unreasonable for AOL to deem a failure or breach
"critical to its business" as provided in subpart (a) above if such failure or
breach results or would result in the breach or nonperformance by AOL of any
obligation to any advertiser on the AOL Network.

limitation, developing the functionality to serve the same advertisement to the
top and bottom of a page, scaling search term capabilities, and undertaking such
other work as may be specified by AOL (collectively, "Development Services").
Notwithstanding the foregoing, AOL shall have no obligation to request or to use
Development Services of IMGIS and may undertake similar work itself or through

2.3 above.

     5.2 FEES FOR DEVELOPMENT SERVICES.

          (a) Provided that, at the time any Development Services are requested
by AOL or are to be performed by IMGIS, AOL is in compliance with all of its

provide the Development Services requested by AOL for no additional
consideration other than reimbursement of the Fully Burdened Costs of the
provision by IMGIS Personnel of such Development Services.

          (b) If, at the time any Development Services are requested by AOL 
or are to be performed by IMGIS: (i) the Implementation Date has not yet 
occurred under the Demographic Data Agreement and no more than twelve months

Personnel of such Development Services plus twenty-five percent (25%) of such 
costs; or (ii) the Implementation Date has not yet occurred under the

confidential information of any Third Parties, except to the extent that the
Technology includes Software licensed from Third Parties which IMGIS has the
right to provide to AOL.

     5.4 WORK FOR HIRE.

          (a) The Parties intend that each Work Product that is a work of
authorship shall be deemed a "work made for hire" within the meaning of the
copyright laws of the United States and any similar laws of other jurisdictions.
To the extent, if any, that IMGIS or its Personnel have rights in any Work
Product notwithstanding the foregoing, including because a Work Product does not
qualify as a "work made for hire," IMGIS hereby irrevocably assigns to AOL, and
agrees that AOL shall be the sole and exclusive owner of, all right, title and
interest in and to the Work Product, including all patent, copyright, trade
secret and other proprietary rights therein that may be secured in any place
under laws now or hereafter in effect.

          (b) To the extent that IMGIS provides Development Services in support
of any modification of the Technology, AOL hereby grants to IMGIS a perpetual,
worldwide, nonexclusive, nontransferable license to use, reproduce, adapt,
transmit, perform and display such modification in connection with the provision
of such Development Services and for no other purpose without AOL's prior
written approval. In the event that IMGIS desires to integrate such modification
in the Technology and obtains AOL's approval thereto, then IMGIS shall reimburse
AOL for any payment made by AOL for such Development Services, or waive such
payment by AOL, in consideration for the grant of such license to IMGIS. IMGIS
may exercise its rights under the foregoing license through Personnel who are
obligated by written agreement to maintain such modification in confidence and
restrict their use of such modification pursuant to terms comparable to those
set forth in Article 13.

          (c) IMGIS shall have valid and enforceable written agreements with all
of its Personnel providing Development Services hereunder containing
confidentiality and nondisclosure obligations comparable in scope to those set
forth in Article 13 and giving IMGIS all rights and authority necessary to

these agreements to AOL upon AOL's request.

          (d) To the extent that IMGIS delivers to AOL any Improvements,
designs, drawings, specifications, documentation, computer software, reports,
training materials, inventions, discoveries and other items that are not Work

pursuant to Section 2.1 above.

     5.5 CHANGE MANAGEMENT PROCESS. Notwithstanding the foregoing provisions of
this Article 5, in the event that AOL implements a version of the Technology
containing any modification to the source code for the Software that adds a
substantially new feature or function to the version of the Technology used by
IMGIS (in contrast to merely correcting what are colloquially known as "bugs" in
such Software or making any other

minor modification to an existing feature or function) then: (a) IMGIS shall not
be obligated to provide Development Services or Technical Support Services for
such Improvement; and (b) in the event that AOL does not request, or IMGIS does
not agree to provide, such Services, the Parties shall work together to devise a
change management process to facilitate the technical support and maintenance of
AOL's version of the Technology containing such Improvement.

Materially Limit or Prohibit the use by IMGIS of Demographic Data, IMGIS shall
provide the Ad Serving Services requested by AOL for no additional consideration
other than reimbursement of the Fully Burdened Costs of the provision by IMGIS
Personnel of such Ad Serving Services, provided, however, that in the event that
IMGIS agrees to provide any Ad Serving Services to any Third Party that is
similarly situated to AOL at a rate that is more favorable to such Third Party
than the consideration payable by AOL under this subpart (a), then IMGIS shall
provide the Ad Serving Services requested by AOL at such Third Party's rate.

          (b) If, at the time any Ad Serving Services are requested by AOL or 
are to be performed by IMGIS: (i) the Implementation Date has not yet 
occurred under the Demographic Data Agreement and no more than twelve months

     6.3 PROVISION OF SERVICES TO OTHER SITES OF AOL PARTNERS. In addition to
the foregoing, upon the request of an AOL Partner, IMGIS agrees to provide Ad

Covered AOL Partner Sites on terms and at rates no less favorable than those
offered by IMGIS to any Third Party that is similarly situated to such AOL
Partner in terms of the volume of advertisements to be served by IMGIS for such
Third Party.

     6.4 REIMBURSEMENT FOR AD SERVING SERVICES. In addition to the fees for Ad

following costs incurred by IMGIS in the provision of Ad Serving Services
requested by AOL for the purposes set forth in Section 6.1 above, and, at AOL's
option, shall provide financing to IMGIS for such costs on mutually agreeable

               of the IMGIS AdForce System required to meet AOL's needs for the
               provision of Ad Serving Services (other than capitalized costs,
               which if financed at the time such costs are incurred, shall be
               reimbursed at the time such costs are amortized), excluding any
               modifications required to scale the Software or other Technology
               to meet AOL's needs;

          (b)  Reimbursement for IMGIS' incremental costs for any additional
               equipment that IMGIS must purchase or lease solely to meet AOL's
               needs for the provision of Ad Serving Services for so long as
               necessary to meet AOL's needs (and, if AOL provides financing for
               such equipment, then, at AOL's option, AOL may become the lessor
               of such equipment to IMGIS), unless AOL determines, in its sole
               discretion, to lease such equipment on its own; and

          (c)  Reimbursement for any additional incremental bandwidth costs
               incurred by IMGIS solely in connection with the provision of Ad
               Serving Services to AOL.

to use the IMGIS AdForce System for the serving and management of Internet
advertisements, subject to agreement between IMGIS and such AOL Partners on the
terms and conditions of such use.

     7.2 COMMISSIONS. If, as a result of marketing efforts by AOL, an AOL
Partner or any other Person enters into an agreement with IMGIS to utilize the
IMGIS AdForce System, then, provided that, as of the time that IMGIS enters into
such agreement with such AOL Partner or other Person, AOL is in compliance with
all of its material obligations under the Demographic Data Agreement and does
not Materially Limit or Prohibit the use by IMGIS of Demographic Data, IMGIS
shall pay to AOL on a quarterly basis the following commissions on the gross
amount of the consideration charged by IMGIS to such AOL Partner or other Person
for use of the IMGIS AdForce System:

          (a)  For the first year of such agreement, the greater of 4% and 
               the highest percentage commission granted by IMGIS at such time 
               to any employee or agent of IMGIS or to any Third Party for 
               similar marketing or sales efforts; and

          (b)  For each succeeding year of such agreement, the greater of 2% 
               and the highest percentage commission granted by IMGIS at such 
               time to any employee or agent of IMGIS or to any Third Party for 
               similar marketing or sales efforts.

     7.3 COMMISSION SHARING. Notwithstanding the provisions of Section 7.2
above, if AOL and any employee or agent of IMGIS or any other Third Party claims
commissions with respect to the same Person (and such Person has not entered
into an agreement with IMGIS solely as a result of AOL marketing efforts), IMGIS
shall not be required to pay total commissions to AOL and such Third Party in
excess of the amount specified in Section 7.2 and IMGIS may apportion the
applicable commission specified in Section 7.2 between AOL and the Third Party
in such manner as IMGIS determines in good faith to be equitable.

              SALE OF ADVERTISEMENTS ON BEHALF OF IMGIS' CUSTOMERS

     8.1 OBLIGATIONS OF IMGIS. IMGIS shall use commercially reasonable efforts
to encourage IMGIS Customers to grant to IMGIS the right to sell interactive
advertisements on their behalf and to obtain the right to assign to AOL the
right to sell such interactive advertisements. Prior to approaching an IMGIS
Customer about obtaining the right to sell interactive advertisements on behalf
of such IMGIS Customer, IMGIS shall discuss with AOL and with no other Person,
within a time period to be agreed upon by the Parties, whether AOL desires to
have IMGIS assign to AOL the right to sell interactive advertisements on behalf
of such IMGIS Customer.

                                                                    CONFIDENTIAL

     8.2 ASSIGNMENT OF RIGHTS TO AOL. In the event that IMGIS obtains the right
to sell interactive advertisements on behalf of any IMGIS Customer and AOL
agrees to have IMGIS assign such right to AOL, IMGIS shall grant to AOL, and AOL
shall obtain, the exclusive right (as to IMGIS and Persons deriving rights
through IMGIS) to sell interactive advertisements on behalf of such IMGIS
Customer to the same extent that IMGIS is entitled to sell such interactive
advertisements; provided, however, that (a) such right to sell interactive
advertisements shall convert to a nonexclusive right if AOL fails to meet
reasonable performance milestones for advertisement sales to be mutually agreed
upon by the Parties within 30 days after the date of IMGIS' assignment to AOL of
its right to sell interactive advertisements on behalf of such IMGIS Customer
and (b) such right shall revert to IMGIS in its entirety in the event that, and
for so long as, AOL ceases to be in compliance with all of its material
obligations under the Demographic Data Agreement or Materially Limits or
Prohibits the use by IMGIS of Demographic Data.

     8.3 REVENUE SHARING AND OTHER CONSIDERATION. AOL shall pay to IMGIS, on a
quarterly basis, fifty percent (50%) of all revenues received by AOL from the
sale of interactive advertisements on behalf of an IMGIS Customer, net of
selling commissions, expenses related to sales, and amounts payable to operators
of the relevant interactive sites. As consideration for the satisfaction by AOL
of additional performance milestones for advertisement sales to be mutually
agreed upon by the Parties within 30 days after the date of IMGIS' assignment to
AOL of its right to sell interactive advertisements on behalf of such IMGIS
Customer, IMGIS and AOL shall agree to either (i) a reduction in the percentage
of revenues payable by AOL from the sale of interactive advertisements on behalf
of such IMGIS Customer or (ii) the issuance to AOL of warrants to purchase
IMGIS' common stock (in addition to those being issued to AOL simultaneously
with the execution of this Agreement), provided that IMGIS has conducted an
initial public offering of its common stock as of the time of such issuance.


                                   ARTICLE 9
                               PAYMENT PROVISIONS

     9.1 PAYMENT PROCEDURES.

          (a) Unless otherwise agreed to in writing by the Parties, all payments
due by AOL for the provision of Services by IMGIS hereunder shall be due and
payable 30 days after the receipt by AOL of a proper invoice therefor from
IMGIS, which invoice shall include such detail and supporting documentation as
AOL may reasonably request.

          (b) Unless otherwise agreed to in writing by the Parties: (i) all
payments due by IMGIS under Article 7 in connection with IMGIS' entrance into an
agreement for use of the IMGIS AdForce System with an AOL Partner or other
Person as a result of AOL marketing efforts shall be paid to AOL within 60 days
after the end of the calendar quarter during which such agreement is entered
into and within 60 days after the end of each succeeding calendar quarter
thereafter; and (ii) all payments due by AOL 

                                       15

                                                                    CONFIDENTIAL

under Article 8 in connection with the sale of interactive advertisements on
behalf of an IMGIS Customer shall be paid to IMGIS within 60 days after the end
of the calendar quarter during which IMGIS assigns to AOL its right to sell
interactive advertisements on behalf of such IMGIS Customer and within 60 days
after the end of each succeeding calendar quarter thereafter.

          (c) All payments due to the payee Party hereunder shall be paid to the
payee Party in U.S. Dollars by wire transfer, or by such other method mutually
agreed upon by the Parties, in each case at the expense of the payor Party, for
value no later than the due date thereof (with 24 hours advance notice of each
wire transfer) to such bank account or accounts as the payee Party shall
designate in writing within a reasonable period of time prior to such due date.

     9.2 LATE PAYMENT. Without limiting the payee Party's rights to pursue any
other remedies at law or in equity, if the payor Party fails to pay any payment
required under this Agreement on or before the due date therefor, then the payor
Party shall pay annually compounded interest on such amount at an annual rate
equal to the lower of (a) the highest rate permitted by applicable law and (b)
the lowest prime rate as published by The Wall Street Journal on or nearest to
such due date plus three percent (3%), which interest shall accrue from the date
the payment not timely made became due until the date such payment is paid in
full.

     9.3 APPLICATION OF PAYMENTS. Any payments received by the payee Party shall
be applied first to the satisfaction of the oldest of any unpaid, accrued
interest charges and, following payment of all such interest charges, to the
satisfaction of the oldest of any unpaid fees or other amounts due hereunder.

     9.4 TAXES.

          (a) All payments required to be made by the payor Party under this
Agreement shall be made free and clear of, and without deduction for, any and
all taxes that are levied on the transfer of such payments to the payee Party.
If any withholding or deductions are required by applicable law, payments shall
be made such that, after such withholding or deductions, the net amount that the
payee Party receives is equal to the amount due hereunder. The payor Party shall
file any information or tax returns with respect to such taxes, and the payor
Party shall indemnify the payee Party from any interest or other payments, fines
or penalties relating to or resulting from any failure, delay or error of the
payor Party in doing so.

          (b) IMGIS shall be responsible for the payment of any and all
transfer, sales, use or similar taxes that are levied on or in connection with
the transfer of the Technology to AOL, including any Improvements.



                                       16

     9.5 BOOKS AND RECORDS. Each Party shall keep full, true and accurate books
of account containing all particulars and reasonable supporting documentation,
in the case of IMGIS, in connection with the provision of Services hereunder and
the determination of any amounts payable to AOL under Article 7, and, in the
case of AOL, in connection with the determination of any amounts payable to
IMGIS under Article 8. All such books of account and reasonable supporting
documentation shall be located at the principal place of business of such Party
and shall be open for inspection by the other Party (the "auditing Party") or
any independent certified public accountant retained by the auditing Party, at a
time mutually acceptable to the Parties during normal business hours but no more
frequently than once each calendar year for three years following the end of the
calendar year to which they pertain (and access shall not be denied thereafter
if reasonably available). If such records are insufficient or any such
inspection discloses a discrepancy in favor of the auditing Party of five
percent (5%) or more of the amounts actually due for any period, then, in
addition to any other rights and remedies available to the auditing Party under
this Agreement, the audited Party shall pay or refund to the auditing Party the
amount of such discrepancy as well as the reasonable cost of such inspection
promptly following such Party's receipt from the auditing Party of the bill or
invoice for such inspection.

                         REPRESENTATIONS AND WARRANTIES

     10.1 MUTUAL REPRESENTATIONS AND WARRANTIES. Each Party represents and
warrants to the other Party that:

          (a)  Such Party has the full corporate right, power and authority to
               execute, deliver and perform this Agreement and to consummate the
               transactions contemplated hereby;

          (b)  The execution, delivery and performance of this Agreement and the
               consummation of the transactions contemplated hereby have been
               duly authorized by all necessary corporate action on the part of
               such Party;

          (c)  This Agreement has been duly executed and delivered by an
               authorized officer of such Party, and is a legal, valid and
               binding obligation of such Party enforceable against it in
               accordance with its terms, except as enforcement may be limited
               by general principles of equity (regardless of whether such
               enforceability is considered in a proceeding at law or in equity)
               and the effect of applicable bankruptcy, insolvency, moratorium
               and other similar laws of general application relating to or
               affecting creditors' rights generally, including, without
               limitation, the effect of statutory or other laws regarding
               fraudulent conveyances and preferential transfers;

                                                                    CONFIDENTIAL

          (d)  Such Party's execution, delivery and performance of this
               Agreement shall not constitute a breach or default under any
               contract or agreement to which such Party is a party or by which
               it is bound or otherwise violate the rights of any Third Party;
               and

          (e)  No consent, approval or authorization of or from any governmental
               entity or any other Person not a Party to this Agreement, whether
               prescribed by law, regulation, contract or agreement, is required
               for such Party's execution, delivery and performance of this
               Agreement or consummation of the transactions contemplated
               hereby.

     10.2 ADDITIONAL REPRESENTATIONS AND WARRANTIES OF IMGIS. IMGIS further
represents and warrants to AOL that:

          (a)  WORKMANLIKE SERVICES. The Services shall be provided in a
               workmanlike manner, in accordance with the standards of care and
               diligence and the level of skill, knowledge and judgment normally
               practiced by nationally-recognized information technology
               services firms in performing services of a similar nature;

          (b)  NONINFRINGEMENT. The Technology does not, and any Improvements
               provided by IMGIS, any Work Products and AOL's use of the
               Technology and Work Products as authorized herein shall not,
               infringe any copyright, trade secret or other proprietary rights
               (except patent rights) of any Third Party or otherwise conflict
               with the rights of any Third Party, and, to the best of IMGIS'
               knowledge, the Technology does not, and any Improvements provided
               by IMGIS, any Work Products and AOL's use of the Technology and
               Work Products shall not, infringe any patent of any Third Party;

          (c)  NO LITIGATION. There is no action, suit, proceeding or
               arbitration pending, and, to the best of IMGIS' knowledge, there
               is no action, suit, proceeding, arbitration or claim threatened,
               concerning the Technology;

          (d)  NO LIENS OR ENCUMBRANCES. Except for the security interest in
               favor of Silicon Valley Bank that has been previously disclosed
               to AOL, the Technology is free from any security interests and
               other liens and encumbrances of Third Parties arising from the
               actions or inactions of IMGIS;

          (e)  NO UNAUTHORIZED CODE. The Technology does not, and any
               Improvements provided by IMGIS shall not, contain any back door,
               time bomb, drop dead device, protect codes, data destruct keys,
               or other software routine designed to disable a computer program

                                                                    CONFIDENTIAL

               automatically with the passage of time or under the control of
               any Person other than AOL. To the best of IMGIS' knowledge, the
               Technology does not, and any Improvements provided by IMGIS shall
               not, contain any virus, Trojan horse, worm or other software
               routine designed to permit unauthorized access or to disable,
               erase, modify, deactivate or otherwise harm software, hardware or
               data; and IMGIS covenants that, prior to or at the time of the
               delivery of any Technology (including any Improvement), IMGIS
               shall test the Technology using a current version of a reputable
               "antivirus" program and remove any such unauthorized codes; and

          (f)  YEAR 2000 COMPLIANCE. All Software and other operational items
               included in the Technology shall: (i) properly execute with all
               date data, whether from years in the same century or different
               centuries, including by yielding correct results in arithmetic
               operations, comparisons and sorting of date fields and in leap
               year calculations; and (ii) not abnormally cease to execute or
               return an error message due to date-related processing.

     10.3 NO OTHER WARRANTIES. THE EXPRESS WARRANTIES IN THIS AGREEMENT SHALL BE
IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.



                                   ARTICLE 11
                                 INDEMNIFICATION

     11.1 INDEMNITY. AOL shall not be liable to IMGIS, any of its Affiliates or
any other Person for, and IMGIS shall indemnify and hold harmless AOL and all
AOL Affiliates, and their respective directors, officers, employees and agents
(collectively, the "AOL Indemnitees"), from and against any Losses incurred
arising out of or resulting from: (a) any infringement of any patent, copyright,
trade secret or other proprietary right by the Technology or any Work Product,
except to the extent that such infringement arises solely from any Improvement
developed by AOL, or by IMGIS to AOL's specifications if IMGIS could not
reasonably have conformed to such specifications while avoiding the
infringement; or (b) the presence of IMGIS' employees or agents on the premises
of AOL or an AOL Affiliate (except those Losses that result solely from the
gross negligence or willful misconduct of AOL or an AOL Affiliate), including,
but not limited to, Losses resulting from injuries to IMGIS' Personnel and
Losses resulting from injuries caused by IMGIS' Personnel.

     11.2 PROCEDURE. Any AOL Indemnitee shall notify IMGIS promptly in writing
of an indemnifiable claim or cause of action under Section 11.1 above upon
receiving notice or being informed of the existence thereof; provided, however,
that failure to notify IMGIS of an indemnifiable claim or cause of action shall
not relieve IMGIS of its 


                                       19
<PAGE>


                                                                    CONFIDENTIAL

obligation to provide indemnification hereunder, except to the extent that such
failure prejudices IMGIS' ability to defend or settle such claim or cause of
action. IMGIS shall assume, at its cost and expense, the sole defense of such
claim or cause of action through counsel selected by IMGIS and reasonably
acceptable to AOL, except that in the case of a conflict of interest between
IMGIS and AOL, IMGIS shall, at IMGIS' cost and expense, provide separate counsel
for AOL selected by AOL. IMGIS shall maintain control of such defense, including
any decision as to settlement; provided that, in the event that IMGIS does not
maintain control of such defense on a timely basis, then, without prejudice to
any other rights and remedies available to AOL under this Agreement, AOL may
take over such defense with counsel of its choosing, at IMGIS' cost and expense.
AOL may, at its option and expense, participate in IMGIS' defense, and if AOL so
participates, the Parties shall cooperate with one another in such defense.
IMGIS shall bear the total costs of any court award or any settlement of such
claim or cause of action approved by IMGIS and all other costs, fees and
expenses related to the resolution thereof (including reasonable attorneys'
fees, except for attorneys' fees for which AOL is responsible in the event that
AOL participates in IMGIS' defense of such claim or cause of action).

     11.3 ABATEMENT OF INFRINGEMENT. If IMGIS reasonably believes it necessary
to do so to minimize its liability under Section 11.1 above, IMGIS may, at its
expense, procure the right for AOL to continue using the Technology or any Work
Product, replace the Technology or any Work Product with a functionally
equivalent noninfringing item, or modify the Technology or any Work Product so
that it is functionally equivalent but noninfringing.


                                   ARTICLE 12
                             LIMITATION ON LIABILITY

     EXCEPT FOR A CLAIM OF INDEMNIFICATION PURSUANT TO ARTICLE 11 OR A BREACH OF
ANY OF THE WARRANTIES SET FORTH IN SECTION 10.2 ABOVE, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER PARTY HEREUNDER FOR ANY INDIRECT, INCIDENTAL, SPECIAL, OR
CONSEQUENTIAL DAMAGES.


                                   ARTICLE 13
                                 CONFIDENTIALITY

     13.1 CONFIDENTIALITY OBLIGATION. Each of AOL and IMGIS (the "Receiving
Party") shall keep, and shall cause their Affiliates to keep, strictly
confidential any information disclosed by the other Party (the "Disclosing
Party") or otherwise made available to the Receiving Party concerning the
Technology or either Party's performance of this Agreement or otherwise
concerning the business, operations, trade secrets or other proprietary
information of the Disclosing Party (whether in written media or otherwise)
("Confidential Information"), using the same degree of care that it uses to
protect its own 


                                       20
<PAGE>

                                                                    CONFIDENTIAL

confidential or proprietary information of a like nature but in no event less
than a reasonable degree of care. "Confidential Information" shall not include
information: (a) which is or becomes generally available to the public other
than as a result of disclosure thereof by the Receiving Party; (b) which is
lawfully received by the Receiving Party on a nonconfidential basis from a Third
Party that is not itself under any obligation of confidentiality or
nondisclosure to the Disclosing Party or any other Person with respect to such
information; (c) which is independently developed by the Receiving Party; or (d)
which was in the Receiving Party's possession prior to receipt from the
Disclosing Party. Each Party shall treat any Technology or Work Product owned by
or assigned to the other Party as Confidential Information of such Party.

     13.2 NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Receiving Party shall
use Confidential Information solely for the purposes of this Agreement and shall
not disclose or disseminate any Confidential Information to any Person at any
time, except for disclosure to its Affiliates and to those of its own and its
Affiliates' directors, officers, employees, accountants, attorneys, advisers and
agents whose duties reasonably require them to have access to such Confidential
Information, provided that such directors, officers, employees, accountants,
attorneys, advisers and agents are bound to maintain the confidentiality of such
Confidential Information to the same extent as if they were Parties hereto.

     13.3 EXCEPTION. The foregoing confidentiality and nondisclosure obligations
shall not apply to Confidential Information: (a) incidentally retained in the
memory of Persons to whom the Receiving Party is permitted to disclose
Confidential Information, other than as the result of an intentional effort to
commit Confidential Information to memory to circumvent the provisions of this
Article 13; or (b) which is required to be publicly disclosed by law or by
regulation; provided, however, that, in such event, the Receiving Party provides
the Disclosing Party with prompt advance notice of such disclosure so that the
Disclosing Party has the opportunity if it so desires to seek a protective order
or other appropriate remedy.

     13.4 SURVIVAL. The confidentiality and nondisclosure obligations of this
Article 13 shall remain in effect for three years following the date hereof or
two years following the termination of this Agreement, whichever is greater,
except with respect to source code and related source code documentation, for
which the obligations of this Article 13 shall survive for so long as the source
code and documentation remain Confidential Information.

     13.5 SOURCE CODE PROTECTION. The Receiving Party shall protect Confidential
Information consisting of source code and related source code documentation from
unauthorized use and disclosure to the same extent that it protects its own
source code (but no less than to a reasonable degree).


                                       21

     13.6 OTHER BUSINESS ACTIVITIES.

          (a) The Disclosing Party agrees that the Receiving Party may currently
or in the future acquire information, either independently developed or legally
received from Third Parties, which may be similar to the Confidential
Information. Nothing in this Agreement shall be construed as a representation
that the Receiving Party does not or shall not have such independently developed
or legally received information.

          (b) Nothing in this Agreement shall be construed as a representation
or agreement to restrict reassignment of the Receiving Party's employees, or in
any manner to affect or limit either Party's present or future business
activities of any nature, including business activities which could be
competitive with the Disclosing Party.

          (c) Nothing in this Agreement shall be construed as a representation
or agreement that the Receiving Party shall not develop or have developed for it
products, concepts, systems or techniques contemplated by or embodied in the
Confidential Information, provided that the Receiving Party does not violate any
of its obligations under this Agreement in connection with such development.


                                   ARTICLE 14
                              TERM AND TERMINATION

     14.1 TERM. This Agreement shall commence as of the date hereof and, unless
terminated in accordance with the provisions of Section 14.2 below, this
Agreement shall remain in full force and effect without expiration.

     14.2 TERMINATION.

          14.2.1 TERMINATION RIGHTS OF AOL. AOL shall have the right to
terminate this Agreement in the event of the breach by IMGIS of, or the failure
of IMGIS to perform, any of its material obligations hereunder and the failure
to remedy such breach or nonperformance within 60 days following the receipt of
written notice of such breach or nonperformance from AOL. Such termination shall
be immediately effective upon the receipt by IMGIS of written notice of
termination from AOL.

          14.2.2 TERMINATION RIGHTS OF IMGIS. IMGIS shall have the right to
terminate this Agreement in the event of:

of the voting power of IMGIS, the acquisition by a Third Party of all or
substantially all of the assets of IMGIS, or the consummation of a merger,
consolidation or similar corporate transaction of IMGIS with or into a Third
Party where the voting securities of IMGIS outstanding immediately prior to
consummation of such transaction are converted into cash or securities
possessing less than fifty percent (50%) of the voting power of the surviving
entity. The obligations of the Parties under this Section 15.3 shall not survive
the termination of this Agreement.

     15.4 FAILURE TO ASSERT RIGHTS IN BANKRUPTCY. AOL's failure to assert its
rights to retain its benefits under this Agreement in accordance with 11 U.S.C.
Section 365(n)(1)(B) shall not be construed as a termination of this Agreement
by AOL under 11 U.S.C. Section 365(n)(1)(A).

     15.5 FURTHER ASSURANCES. Upon the request of either Party, the other Party
shall sign and deliver any assignments or other necessary documents and
otherwise assist the requesting Party to obtain, maintain, perfect or enforce
any of the requesting Party's rights hereunder.

either Party occurs which delays or renders impossible the performance of that
Party's obligations under this Agreement on the dates herein provided, such

whole or in part, by either Party without the prior written consent of the other
Party, except that: (a) AOL may assign any of its rights or obligations

the rights and obligations of either Party under this Agreement may be assigned
without the other Party's consent to a Third Party acquiring all or
substantially all of the assets of the assigning Party or to the surviving
entity upon the consummation of any merger, consolidation or similar corporate
transaction of the assigning Party with or into a Third Party. Any attempted
assignment by either Party without the consent of the other Party in any
circumstances other than those described in the immediately preceding sentence
shall be null and void. This Agreement shall inure to the benefit of and be
binding upon each of the Parties hereto and their respective successors and
permitted assigns.

     15.13 ENTIRE AGREEMENT. The terms and conditions herein contained
constitute the entire agreement between the Parties relating to the subject
matter of this Agreement and shall supersede all previous communications between
the Parties with respect to the subject matter of this Agreement, except for the
Letter Agreement between the Parties dated as of April 14, 1998 and the
Confidential Non-Disclosure Agreement between the Parties dated as of April 15,

     15.16 SEVERABILITY. In the event that any provision of this Agreement is
held to be illegal, invalid or unenforceable in a final, unappealable order or
judgment (each such provision, an "invalid provision"), then such provision
shall be severed from this Agreement and shall be inoperative, and the Parties
promptly shall negotiate in good faith a lawful, valid and enforceable provision
that is as similar to the invalid provision as may be possible, while the
remaining provisions of this Agreement shall remain binding on the Parties
hereto.

          15.17 HEADINGS. The descriptive headings of the several articles and
sections of this Agreement are inserted for convenience only and do not
constitute a part of this Agreement.

          15.18 NO WAIVER OF RIGHTS. No failure or delay on the part of either
Party in the exercise of any power or right hereunder shall operate as a waiver
thereof. No single or partial exercise of any right or power hereunder shall
operate as a waiver of such right or of any other right or power. The waiver by
either Party of a breach of any provision of this Agreement shall not operate or
be construed as a waiver of any other or subsequent breach hereunder.

          15.19 REMEDIES CUMULATIVE; SPECIFIC PERFORMANCE. All rights and
remedies granted to either Party under this Agreement are cumulative and in
addition to, and not in lieu of, any other rights or remedies otherwise
available to such Party at law or in equity. The Parties agree that any breach
by either Party of, or failure of either Party to perform, any obligation under
this Agreement shall constitute immediate and irreparable damage to the other
Party which cannot be fully and adequately compensated in money damages and
that, in the event of such breach or failure, the other Party shall be entitled
to injunctive relief and specific performance in addition to any other remedies
to which it may be entitled at law or in equity.

          15.20 CONFIDENTIALITY OF AGREEMENT. Each Party shall maintain the
confidentiality of this Agreement and all provisions of this Agreement and,
without the prior consent of the other Party, neither Party shall make any press
release or other public announcement of or otherwise disclose this Agreement or
any of its provisions to any Third Party (a) other than to its Affiliates and to
its own and its Affiliates' directors, officers, employees, attorneys and
accountants, and to the lead underwriter engaged by IMGIS in connection with any
offering of securities of IMGIS, whose duties reasonably require familiarity
with this Agreement, provided that such Persons (including any such lead
underwriter) are bound to maintain the confidentiality of this Agreement, and
(b) except for such disclosure as may be required by applicable law or
regulation, in which case the disclosing Party shall provide the other Party
with prompt advance notice of such disclosure so that the other Party has the
opportunity if it so desires to seek a protective order or other appropriate
remedy; provided that, in connection with any offering of securities of IMGIS,
IMGIS shall provide in advance to AOL for review the form and content of any
disclosure of this Agreement or any of its provisions that may be required by
applicable law or regulation and, to the extent consistent with its disclosure
obligations under applicable law, include

                                                                    CONFIDENTIAL

such modifications to such disclosure as may be reasonably requested by AOL
(except that IMGIS may file this Agreement as an exhibit to its registration
statement if it would constitute a "material agreement" under applicable law or
regulation and IMGIS shall use its reasonable best efforts to obtain
confidential treatment of the portions of this Agreement that meet the SEC
qualifications for confidential treatment if so requested by AOL). The
confidentiality obligations of this Section 15.20 would apply, inter alia, to
any disclosure by IMGIS of this Agreement or of any provisions of this Agreement
to any customer or potential customer of IMGIS and any such disclosure would
constitute a breach of this Section 15.20. The Parties agree that any breach of
the provisions of this Section 15.20 by either Party, including, without
limitation, by any directors, officers or employees of such Party, would
constitute a breach by such Party of a material obligation hereunder for which
the other Party shall have the right, notwithstanding the provisions of Section
14.2 above, to immediately terminate this Agreement without allowance of any
period to remedy such breach, such termination to be immediately effective upon
the receipt by the breaching Party of written notice of termination from the
nonbreaching Party.

     15.21 USAGE. Wherever any provision of this Agreement uses the term
"including" (or "includes"), such term shall be deemed to mean "including
without limitation" and "including but not limited to" (or "includes without
limitation" and "includes but is not limited to") regardless of whether the
words "without limitation" or "but not limited to" actually follow the term
"including" (or "includes").

             IN WITNESS WHEREOF, the Parties hereto have caused this Agreement
to executed by their duly authorized officers as of the date first above
written.

     through which 24/7 Media will be able to (a) generate ad tags, (b) schedule
     advertising to run in the online environments in which 24/7 Media places
     those ad tags, and (c) generate reports on such advertising. In addition,
     AdForce will maintain an AdForce server complex from which AdForce will
     electronically deliver advertising scheduled by 24/7 Media to the online
     environments containing the ad tags placed by 24/7 Media. The delivery of
     "Impressions," defined as the transmission of advertisements by AdForce to
     an AdForce ad tag, will be verified by monthly third-party audits of the
     AdForce service, conducted by the Audit Bureau of Verification Services,
     Inc. or other third party chosen by AdForce.

2.   ADFORCE SERVICE.  (a) GENERALLY.  The AdForce service includes the
     targeting features and reports listed in Exhibit A.  AdForce will use  best
     efforts to accommodate 24/7 Media's custom report requests; any custom
     reports agreed to by both parties will be developed by AdForce at the rate
     set forth on Exhibit A.  Features added to the AdForce service in the
     future (e.g. demographic targeting, behavior tracking) may be included
     without charge in the AdForce service, or in AdForce's sole discretion, be
     subject to additional fees.  The AdForce services include the functionality
     described in Section 1 and Exhibit A, plus telephone client services
     support from the hours of 6 a.m. to 6 p.m., Pacific Standard Time,
     Monday-Friday, excluding major holidays.  AdForce will also maintain 24 x 7
     technical service support via phone, cell phone or pager.  Pricing for the
     AdForce service is detailed in Exhibit A.  AdForce will exercise all
     commercially reasonable efforts at all times to correct errors in the
     Client and in software used to operate the AdForce server complex.

               (b)  CERTAIN TECHNICAL AND INTEGRATION SUPPORT.  (i) AdForce
     shall participate when reasonably requested, in technical meetings with
     24/7 Media staff, and shall furnish 24/7 Media within ninety (90) days from
     the Effective Date a production monitoring page and access to AdForce's
     customer issues tracking system (excluding in either case metrics or issues
     unique to non-24/7 Media customers or campaigns).  (ii) AdForce will use
     commercially reasonable efforts to design and implement, at 24/7 Media's
     request and at 24/7 Media's expense on a time and materials basis, an
     interface to access 24/7 Media's Profilz database to enable 24/7 Media, on
     an exclusive basis, to deliver targeted advertising to its customers.
     Promptly following execution of this Agreement, and at 24/7 Media's
     request, AdForce and 24/7 Media personnel will develop a plan and budget
     for such development, and determine any incremental pricing to be charged
     by AdForce for ad management and delivery on such new service. AdForce
     shall not, however, be precluded in any way from developing its own
     targeting advertising products or from cooperating with third parties on
     other advertising services or products, whether targeted or otherwise.
     (iii) AdForce is presently delivering advertisements on behalf of 24/7
     Media using a combination of 24/7 Media ad tags and AdForce ad tags.
     AdForce agrees to cooperate with 24/7 Media in good faith to convert any
     existing AdForce ad tags to 24/7 Media ad tags, and that 24/7 Media may use
     the AdForce system to generate 24/7 Media ad tags for all future 24/7 Media
     campaigns.

               (c)  CAPACITY.  Provided 24/7 Media provides AdForce the
     impression forecasts referenced in Section 3 below, and that 24/7 Media
     meets its guarantee (or compensates AdForce for impression deliveries short
     of the guarantee) provided in Section 3 below, AdForce covenants and
     warrants it will have the capacity to serve properly on behalf of 24/7
     Media the impression volumes requested by 24/7 Media in its impression
     forecasts.

3.   24/7 MEDIA OBLIGATIONS. 24/7 Media agrees to implement 24/7 Media ad tags
     using the process described in the AdForce User Guide and Help
     documentation.  Should the average file size of 24/7 Media's advertisements
     exceed [*] kilobytes, as reasonably determined by AdForce on a monthly
     basis, 24/7 Media agrees to pay the incremental fee listed in Exhibit A to
     compensate for AdForce's higher bandwidth costs.  24/7 Media agrees to
     provide AdForce quarterly volume forecasts (with expected monthly volumes)
     of Impressions to be delivered using the AdForce service; these forecasts
     will be provided no later than thirty (30) days prior to the beginning of
     each calendar quarter.  Finally, 24/7 Media agrees that during the  Term
     (as defined in Exhibit A below) hereof, 24/7 Media will manage and deliver
     through the AdForce service not less than [*] percent ([*]%) of the
     impressions anticipated in its quarterly forecasts; if, for any reason
     other than AdForce's default, 24/7 Media fails to deliver this guaranteed
     amount, 24/7 Media will pay to AdForce the difference between [*] of the
     guaranteed amount and the amount actually served, multiplied by the
     applicable CPM rate set forth on Exhibit A.

     Agreement, 24/7 Media will have the right to use the Client in its offices

     acknowledge that 24/7 Media owns the domain name www.247media.com and that
     this ownership shall survive the termination of this Agreement.  24/7 Media
     may not copy, modify, alter, sell, distribute or sublicense the Client or
     reverse assemble, reverse compile or otherwise attempt by any other method
     to create or derive the source programs of the AdForce service or the
     Client, nor authorize or contract with third parties to do the same.

5.   DATA RIGHTS. All data AdForce collects or stores in managing and delivering
     ads for 24/7 Media which specifically pertain to 24/7 Media or its

     generating reports and generating future media plans, including information
     about sites in the media plan, impression limits, ad costs, creatives,
     campaign results, click-through rates or transaction rates (collectively
     "Campaign Data"), shall be owned by and is proprietary and confidential to

     purpose where such data can be specifically associated with the identity of
     24/7 Media or its clients; provided, however, that AdForce may use such
     Campaign Data for reporting  where such information is aggregated with
     information from other AdForce customers and/or not specifically
     identifiable as 24/7 Media information.  Further, 24/7 Media shall own all
     data collected or stored as a side effect of serving or tracking ads that
     is not Campaign Data ("Clickstream Data").  However, AdForce can use
     Clickstream Data for any purposes that do not expose Campaign Data to any
     third party, and will not be required to store such information for more
     than twelve (12) months.  24/7 Media may request at any time during the
     term of the Term Sheet, or any renewal term, to receive copies of
     Clickstream Data from AdForce.  AdForce will supply such data at the
     following rates:  $[*] per month for files delivered daily, $[*] per
     month for files delivered monthly for the preceding month, and $[*] for
     files generated in the preceding 12 months (provided 24/7 Media makes the
     request within thirty (30) days of the end of such year).

6.   CONFIDENTIALITY. Any 24/7 Media passwords to AdForce, AdForce user guides,
     the AdForce Client, and the AdForce "help" documentation, whether on-line
     or in printed form, are confidential and proprietary to AdForce. As
     indicated above, all Campaign Data is proprietary and confidential to 24/7
     Media.  Such information shall not be used, disclosed or reproduced by the
     other party without the consent of the party providing said information,
     except for any information, data or material which: (a) at the time of
     disclosure to the receiving party was known or in the possession of the
     receiving party; (b) is independently developed by the receiving party; (c)
     is generally available to the public without any breach of this Agreement.

7.   INDEMNIFICATION.  (a) 24/7 MEDIA.  Subject to subsection (b), 24/7 Media
     shall indemnify and hold harmless AdForce from any liability and damages
     and costs (including reasonable costs and attorneys' fees) arising out of
     or relating to advertising placed by 24/7 Media using the AdForce service,
     including, without limitation, failure of the AdForce service or the
     Client, content, libel, invasion of privacy, and rights of publicity;
     provided: (i) AdForce promptly notifies 24/7 Media of such claims; (ii)
     24/7 Media has sole control of the defense and settlement of such claims
     and is not responsible for any settlement that it does not approve in
     writing; and (iii) AdForce renders all assistance required.

               (b) ADFORCE.  AdForce shall indemnify and hold harmless 24/7
     Media from any third party claims and liabilities for infringement arising
     out of or relating to 24/7 Media's use of the Client pursuant to this
     Agreement, provided that: (i) 24/7 Media promptly notifies AdForce of such
     claims; (ii) AdForce has sole control of the defense and settlement of such
     claims and is not responsible for any settlement that it does not approve
     in writing; and (iii) 24/7 Media renders all assistance required. If an
     injunction is entered against 24/7 Media's use of the Client, AdForce will,
     at its option, (A) obtain a license permitting such use, (B) modify the
     Client to avoid the infringement, or (C) if it cannot reasonably do either
     of the foregoing, terminate 24/7 Media's access to the Client and this
     Agreement.

8.   WARRANTY.  24/7 Media warrants that it is free to enter into this Agreement
     and that this Agreement constitutes the valid and binding obligation of
     24/7 Media, enforceable in accordance with its terms. AdForce warrants that

     human intervention whatsoever (i) the overall operation, functions and
     performance of the AdForce system will employ in connection with its
     obligations under this Agreement (the "AdForce System") will be unaffected
     in any way by any date data, date setting, date value, date input or other
     date related data and any combination thereof (collectively with records
     using such data, the "DATE DATA"), whether falling on, after or before
     September 9, 1999, December 31, 1999 or January 1, 2000 (collectively, the
     "MILLENNIUM DATES"); (ii) the AdForce System will correctly and accurately,
     without human intervention, store, define, merge, archive, display,
     recognize, return, manage, extract, support, calculate, compare,

     assigned special values in a manner that correctly resolves any ambiguities
     as to intended century date and shall correctly reflect each century in
     Date Data values and Date Data interface values, and the AdForce System
     does and will have the ability to properly interface with internal and
     external applications or systems of third parties with whom AdForce
     exchanges data electronically, including vendors, suppliers, customers,
     banks and governmental agencies. AdForce warrants to 24/7 that the AdForce
     System shall conform to the warranties in this SECTION from and at all
     times during the term of this Agreement, before, on or after a Millennium
     Date, regardless of whether 24/7 uses the AdForce System on, before or
     after a Millennium Date.

     EXCEPT AS SPECIFIED IN THIS SECTION 8, ADFORCE HEREBY DISCLAIMS ALL
     WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY AND ALL

     termination of this Agreement for any reason, the parties will use best
     efforts to effect an orderly transition of 24/7 Media to another ad serving
     solution, and each party will return all Confidential Information of the

13.  GENERAL. This Agreement is the complete and exclusive statement of the
     mutual understanding of the parties and supersedes and cancels all previous
     written and oral agreements and communications relating to the subject
     matter of this Agreement.  No failure or delay in exercising any right
     hereunder will operate as a waiver thereof, nor will any partial exercise
     of any right or power hereunder preclude further exercise. Any waivers or
     amendments shall be effective only if made in writing. If any provision of
     this Agreement shall be adjudged by any court of competent jurisdiction to
     be unenforceable or invalid, that provision shall be limited or eliminated

     remain in full force and effect and enforceable. This Agreement shall be
     governed by the law of the State of New York without regard to the
     conflicts of law provisions thereof. The prevailing party in any action to

     courts for that purpose.  The parties waive personal service in connection
     with any such arbitration; any process or other papers under this provision
     may be served outside California or New York by registered mail, return
     receipt requested, or by personal service, provided a reasonable time for
     appearance or response is allowed.  The decision of the arbitrator shall be
     final and binding on the parties.  The parties shall equally divide all

                                LICENSE AGREEMENT


        This LICENSE AGREEMENT (the "Agreement") is entered into as of 
February 1, 1999 (the "Effective Date") by and between Netscape 
Communications Corporation, a Delaware corporation having its principal 
office at 501 East Middlefield Road, Mountain View, California 94043 
("NETSCAPE"), and IMGIS, INC., a California corporation doing business as 
"AdForce" and having its principal office at 10101 N. DeAnza Boulevard, Suite 
210, Cupertino, California 95014 ("ADFORCE").


                                   WITNESSETH:


        WHEREAS, the parties hereto wish to provide the terms and conditions 
under which ADFORCE will supply NETSCAPE Ad Serving Services (as defined 
below) for the term provided herein; and 

        WHEREAS, NETSCAPE desires to obtain, and ADFORCE is willing to grant 
to NETSCAPE at the times and on the specific conditions stated herein, a 
worldwide, perpetual and nonexclusive license to use, and to serve interactive 
advertisements using, ADFORCE's ad serving, trafficking, targeting and related 
technology on the terms and subject to the conditions set forth herein.

        NOW, THEREFORE, in consideration of the foregoing, of the mutual 
covenants and undertakings contained herein and of other good and valuable 
consideration, the receipt and sufficiency of which are hereby acknowledged, 
the Parties, intending to be legally bound, hereby agree as follows:


                                   ARTICLE 1
                                  DEFINITIONS

        In addition to other terms defined elsewhere herein, the following 
terms will have the following meanings when used herein (any term defined in 
the singular will have the same meaning when used in the plural and vice 
versa, unless stated otherwise):

        1.1 "AD SERVING SERVICES" has the meaning set forth in Section 6.1 
below.

        1.2 "AFFILIATE" of any specified Person means any other Person that 
directly, or indirectly through one or more intermediaries, controls, is 
controlled by, or is under common control with the specified Person.

that would in turn give such site the right to impressions on other sites 
within that banner exchange network. Typically, such sites receive one 
impression on the banner exchange network for every two they give, with the 
balance available for the banner exchange network to sell to advertisers. The 
program is targeted at small sites with low-value inventory which are not 
candidates for the AdForce Service and, therefore, noncompetitive with 
ADFORCE. Examples of banner exchange networks include LinkExchange, SmartAge 
and Hyperbanner.

stock or other equity interests of such Person entitled to vote for the 
election of members of the Board of Directors or similar governing body of 
such Person; provided, however, that such Person shall cease to be a NETSCAPE 
Affiliate if and when such equity interest becomes less than twenty-five 
percent (25%) for any reason other than as a result of dilution, and 
provided, further, that if such equity interest becomes less than twenty-five 
percent (25%) as a result of dilution, such Person shall cease to be a 
NETSCAPE Affiliate if and when such percentage equity interest is further 
reduced for any reason other than as a result of dilution.

        1.5  "COVERED NETSCAPE PARTNER SITE PAGES" means the interactive site 
pages of a NETSCAPE Partner provided that: (a) such site pages are marketed 
or promoted, and intended to be accessible, to Netcenter visitors only, 
meaning links to such Site Pages are available only through Netcenter and not 
from the Partner site; and (b) NETSCAPE or a NETSCAPE Affiliate has the right 
to serve and to sell the advertising inventory for such site.

                 such contractor) payable to such contractor by ADFORCE 
                 multiplied by the percentage of time spent by such

                                GRANT OF LICENSE

    2.1  LICENSE GRANT.

         (a)  Subject to the terms and conditions hereof, and effective upon 
completion by NETSCAPE of its pending merger (the "AOL Merger") with a 
wholly-owned subsidiary of America Online, Inc., ADFORCE grants to NETSCAPE 
a perpetual, worldwide, nonexclusive, nontransferable (except as set forth in 
Section 15.12 below), royalty-free license under all of ADFORCE's patent, 
copyright, trade secret and other proprietary rights to use, reproduce, 
adapt, transmit, perform, display and otherwise practice the Technology or 
any part thereof, other than commercially available Third Party software that 
ADFORCE has the right to provide to NETSCAPE only upon payment of a fee to 
the Third Party, solely for the Permitted Purposes. If for any reason the AOL 
Merger is affirmatively canceled or does not otherwise occur within six (6) 
months from the date hereof, then the license grants set forth herein and the 
provisions set forth in Articles 3 and 4.1 and 4.2 below shall be null and 
void, and NETSCAPE shall have no license rights whatsoever to the Technology. 
In such event, within sixty (60) days from the earlier of (i) the date the 
AOL Merger is affirmatively canceled or (ii) August 1, 1999, NETSCAPE and 
ADFORCE will enter into a source code escrow agreement in form and substance 
mutually acceptable to the parties. Under such agreement, ADFORCE will 
deposit the source and object code for the Technology into an escrow with a 
third party escrow company acceptable to the Parties. Such source code escrow 
agreement will provide for the release of the source and object code to 
NETSCAPE if ADFORCE ceases to do business, undergoes a bankruptcy or 
insolvency proceeding, makes an assignment for the benefit of creditors or 
experiences similar occurrences. In the event of a critical failure as 
described in Section 4.3 below, such source code escrow agreement will 
provide for the temporary release of the source and object code to NETSCAPE 
for the duration of such critical failure. If ADFORCE breaches this 
Agreement, the source code escrow agreement will provide for the release of 
the source and object code to NETSCAPE, which NETSCAPE will then be able to 
use for a period of one year from the date of such breach, after which period 
NETSCAPE shall have no further rights of use. For purposes of this section 
only, in order to be in breach of the Performance Metrics of Exhibit A, 
ADFORCE must be in breach of at least 2 of the 4 Performance Metrics 
described in Exhibit A, including at least one of either Exhibit A, Section 
7(A) or 7(B).

         (b)  Subject to subsection 2.1(a) above, if any Technology consists 
of commercially available Third Party software that ADFORCE has the right to 
provide to NETSCAPE only upon payment of a fee to the Third Party, NETSCAPE 
may, by written notice to ADFORCE and payment of such fee, require ADFORCE to 
grant to NETSCAPE a perpetual, worldwide, nonexclusive, nontransferable 
(except as set forth in Section 15.12 below), royalty-free (except for such 
fee) license under all applicable patent, copyright, trade secret and other 
proprietary rights to use, reproduce, adapt, transmit perform, display and 
otherwise practice such Technology or any part thereof solely for the 
Permitted Purposes (but only to the extent of ADFORCE's rights in such 
Technology).

         (c)  The Parties agree that neither the licenses to be granted in 
this Section 2.1 nor any other provisions of this Agreement impose or shall 
be construed to impose any obligation upon NETSCAPE to use or otherwise 
practice the Technology. ADFORCE agrees that it shall not bring any action in 
law or equity, or any other judicial or nonjudicial proceeding, against 
NETSCAPE asserting that the use by NETSCAPE of any patent rights claiming the 
Technology that are now or hereafter owned by or licensed to ADFORCE or any 
other Technology infringes or otherwise violates any patent, copyright, trade 
secret or other proprietary rights of ADFORCE.

    2.2  EXERCISE OF RIGHTS. Following effectiveness of the licenses to be 
granted herein pursuant to Section 2.1(a) above, NETSCAPE may exercise its 
rights in and to the Technology at any location, on any hardware, and with 
respect to all, none or any portion or combination of the Technology. 
Notwithstanding the foregoing, any proposed exercise by NETSCAPE of such 
rights shall be subject to the provisions of Section 15.2 below. Except as 
set forth in Section 6.1 below, nothing in this Agreement shall obligate 
NETSCAPE to use the Technology or to use a designated server or site in 
connection with such Technology.

    2.3  USE OF PERSONNEL. NETSCAPE may exercise its rights hereunder through 
Personnel who are obligated by written agreement to maintain the Technology 
in confidence and restrict their use of the Technology pursuant to terms 
comparable to those set forth in Article 13.

copy of the object code for the Software; (b) one copy of available technical 
and user documentation for the Technology in printed and machine-readable 
format as available; and (c) one machine-readable copy of the source code for 
the Software. Such delivery shall be transmitted electronically or by any 
other means agreed upon by ADFORCE and NETSCAPE.

    3.2  DELIVERY OF IMPROVEMENTS AND OTHER TECHNOLOGY.

         (a)  Provided the license becomes effective per Section 2.1(a) 
above, ADFORCE shall use commercially reasonable efforts regularly to develop 
Improvements to adapt the Technology to changes in related technologies and 
in market and user requirements and to remain competitive with alternative 
technologies for the serving, trafficking and/or targeting of advertisements 
or other information or materials.

         (b)  Provided the license becomes effective per Section 2.1(a) 
above, at such times as reasonably requested by NETSCAPE, ADFORCE shall 
provide NETSCAPE with any Improvements made by or on behalf of ADFORCE and 
any other Technology

requested by NETSCAPE that is existing and not then in the possession of 
NETSCAPE. In addition, provided the license becomes effective per Section 
2.1(a) above and commencing no later than forty-five (45) days after such 
time that NETSCAPE determines to deploy the Technology in whole or in part 
(the "Deployment Date"), ADFORCE shall provide to NETSCAPE on a quarterly 
basis the then current version of the source code for the Software and shall 
provide to NETSCAPE any and all Improvements, including upgrades, updates, 
enhancements, patches and "bug" fixes, prior to or concurrently with their 
installation or release, by any means requested by NETSCAPE (including 
electronically), along with the applicable documentation related to such 
Improvement.

         (c)  Provided the license becomes effective per Section 2.1(a) 
above, ADFORCE shall provide all Improvements and other Technology, other 
than Improvements provided in the provision of Development Services, to 
NETSCAPE without any additional charge or fee. Notwithstanding the foregoing, 
(i) if the license becomes effective under Section 2.1(a) above, but the 
Parties have not executed a Demographic Data Agreement, or (ii) if the 
license becomes effective under Section 2.1(a) above and the Parties have 
executed a Demographic Data Agreement but NETSCAPE ceases to be in compliance 
with all of its material obligations under the Demographic Data Agreement or 
Materially Limits or Prohibits the use by ADFORCE of Demographic Data, and 
NETSCAPE desires to continue receiving Improvements from ADFORCE, then 
NETSCAPE shall pay to ADFORCE on an annual basis a reasonable update fee to 
be agreed upon by the Parties for all Improvements developed for so long as 
NETSCAPE is not in compliance with all of its material obligations under the 
Demographic Data Agreement or Materially Limits or Prohibits the use by 
ADFORCE of Demographic Data; provided that such fee shall not exceed (i) 
ADFORCE's customary update fees for such Improvements in arm's length 
transactions with its licensees, if ADFORCE then licenses the Technology to 
Third Parties, or (ii) update fees charged by other licensors of comparable 
systems for serving, trafficking and/or targeting of advertisements or other 
information or materials, but not less than ADFORCE's cost of providing such 
Improvements, if ADFORCE does not then license the Technology to Third 
Parties.

         (d)  Provided the license becomes effective per Section 2.1(a) above, 
at NETSCAPE's request, ADFORCE shall identify to NETSCAPE, and provide 
NETSCAPE reasonable information and assistance in furtherance of NETSCAPE's 
efforts to acquire, at NETSCAPE's own expense, commercially available Third 
Party software licensed to ADFORCE for use in connection with the Technology 
and not sublicensed to NETSCAPE under Section 2.1(a) or (b) above.

                                                                  CONFIDENTIAL

NETSCAPE's written request, reasonable technical training, support, 
documentation and assistance relating to the interactive content (including 
interactive advertisement) serving, trafficking, targeting and related 
functions of the Technology (collectively, "Technical Support Services"). 
The Technical Support Services shall, at a minimum, enable NETSCAPE, without 
the aid of ADFORCE or any other Person, to develop, enhance and maintain the 
Technology (including the source code for the Software) for use by NETSCAPE 
to the same extent as ADFORCE.

          (b)  Commencing no later than forty-five (45) days after the 
Deployment Date, the Technical Support Services, if required hereunder, shall 
include, without limitation: (i) the regular provision by ADFORCE of 
qualified Personnel able to resolve problems in the operation of the 
Technology on-site at NETSCAPE's data centers in Silicon Valley; and (ii) the 
provision by ADFORCE of telephone access twenty-four (24) hours a day, seven 
(7) days a week, to qualified Personnel able to resolve problems in the 
operation of the Technology, via a designated telephone support number.

     4.2  FEES FOR TECHNICAL SERVICES SUPPORT.

          (a)  Subject to subsection 4.2(b) below, provided that at the time 
any Technical Support Services are requested by NETSCAPE or are to be 
performed by ADFORCE hereunder, NETSCAPE is in compliance with all of its 
material obligations under a validly executed Demographic Data Agreement and 
does not Materially Limit or Prohibit the use by ADFORCE of Demographic Data, 
ADFORCE shall provide the Technical Support Services requested by NETSCAPE 
for no additional consideration other than reimbursement of the Fully 
Burdened Costs of the provision by ADFORCE Personnel of such Technical 
Support Services.

          (b)  If, at any time prior to July 15, 1999 any Technical Support 
Services are requested to be performed by ADFORCE hereunder and (i) the 
parties have not executed a Demographic Data Agreement, or (ii) the 
Implementation Date has not yet occurred under a validly executed Demographic 
Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs 
of the provision by ADFORCE Personnel of such Technical Support Services plus 
twenty-five percent (25%) of such costs. If, at any time on or after July 15, 
1999 any Technical Support Services are required to be performed by ADFORCE 
hereunder and (i) the parties have not executed a Demographic Data Agreement, 
or (ii) the Implementation Date has not yet occurred under a validly executed 
Demographic Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully 
Burdened Costs of the provision by ADFORCE Personnel of such Technical 
Support Services plus forty percent (40%) of such costs.

          (c)  If, following the occurrence of the Implementation Date under 
a validly executed Demographic Data Agreement, at the time any Technical

NETSCAPE shall pay to ADFORCE the Fully Burdened Costs of the provision by 
ADFORCE Personnel of such Technical Support Services plus twenty-five percent 
(25%) of such costs.

     4.3  WARRANTY.  If the Technology or Services as described in Exhibit A 
fail to conform to or perform in accordance with the technical or user 
documentation provided by ADFORCE (other than as a result of operator error, 
accident, or misuse or alteration of the Technology by a Person not under 
ADFORCE's direction or control), or in the event of a breach of the 
warranties set forth in Section 10.2(e) or 10.2(f) below, then ADFORCE, at 
its expense and without any payment by NETSCAPE for Technical Support or 
other Services, shall use commercially reasonable efforts to cure such 
failure or breach as soon as practicable, but in any event:

          (a)  For a "critical" failure or breach, such as the Technology, or 
               other software, hardware or other technology with which the 
               Technology is interfacing or integrating, ceasing to execute a 
               function that NETSCAPE reasonably deems critical to its 
               business, ADFORCE shall provide at least a temporary 
               workaround or fix within two (2) hours of receiving notice of 
               such failure or breach and shall cure such failure or breach 
               within three (3) business days of receiving notice of such 
               failure or breach; and

          (b)  For any other failure or breach that is not a "critical" 
               problem, ADFORCE shall provide at least a temporary workaround 
               or fix within three (3) business days of receiving notice of 
               such failure or breach and shall cure such failure or breach 
               within fifteen (15) days after receiving notice of such 
               failure or breach.

Without limiting the generality of the foregoing, ADFORCE agrees, by way of 
example, that it shall not be unreasonable for NETSCAPE to deem a failure or 
breach "critical to its business" as provided in subpart (a) above if such 
failure or breach results or would result in the breach or nonperformance by 
NETSCAPE of any obligation to any advertiser on the NETSCAPE Network.

shall undertake the reasonable development of Improvements as necessary to 
customize the interactive content (including interactive advertisement) 
serving, trafficking, targeting and related functions of the Technology to 
meet NETSCAPE's needs (collectively, "Development Services"). Notwithstanding 
the foregoing, NETSCAPE shall have no obligation to request or to use 
Development Services of ADFORCE and may undertake

similar work itself or through independent contractors other than ADFORCE, 
subject to the provisions of Section 2.3 above.

          5.2  FEES FOR DEVELOPMENT SERVICES.

               (a)  Provided that, at the time any Development Services are 
requested to be performed by ADFORCE hereunder, NETSCAPE is in compliance 
with all of its material obligations under a validly executed Demographic 
Data Agreement and does not Materially Limit or Prohibit the use by ADFORCE 
of Demographic Data, ADFORCE shall provide the Development Services requested 
by NETSCAPE for no additional consideration other than reimbursement of the 
Fully Burdened Costs of the provision by ADFORCE Personnel of such 
Development Services.

               (b)  If, at any time prior to July 15, 1999 any Development 
Services are requested to be performed by ADFORCE hereunder and (i) the 
parties have not executed a Demographic Data Agreement, or (ii) the 
Implementation Date has not yet occurred under a validly executed Demographic 
Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs 
of the provision by ADFORCE Personnel of such Development Services plus 
twenty-five percent (25%) of such costs. If, at any time on or after July 15, 
1999 any Development Services are required to be performed by ADFORCE

Data Agreement or Materially Limits or Prohibits the use by ADFORCE of 
Demographic Data, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs 
of the provision by ADFORCE Personnel of such Development Services plus 
twenty-five percent (25%) of such costs.

          5.3  ORIGINAL WORK.  Any Work Products either shall be the original 
work of ADFORCE and its Personnel or shall be items licensed by Third Parties 
that ADFORCE has the right to provide to NETSCAPE and that ADFORCE identifies 
as such to NETSCAPE in writing. ADFORCE shall not disclose to NETSCAPE, or 
induce NETSCAPE to use, the trade secrets or other confidential information 
of any Third Parties, except to the extent that the Technology includes 
Software licensed from Third Parties which ADFORCE has the right to provide 
to NETSCAPE.

          (a)  The Parties intend that each Work Product that is a work of 
authorship shall be deemed a "work made for hire" within the meaning of the 
copyright laws of the United States and any similar laws of other 
jurisdictions. To the extent, if any, that ADFORCE or its Personnel have 
rights in any Work Product notwithstanding the foregoing, including because a 
Work Product does not qualify as a "work made for hire," ADFORCE hereby 
irrevocably assigns to NETSCAPE, and agrees that NETSCAPE shall be the sole 
and exclusive owner of, all right, title and interest in and to the Work 
Product, including all patent, copyright, trade secret and other proprietary 
rights therein that may be secured in any place under laws now or hereafter 
in effect.

          (b)  To extent that ADFORCE provides Development Services in support 
of any modification of the Technology, NETSCAPE hereby grants to ADFORCE a 
perpetual, worldwide, nonexclusive, nontransferable license to use, 
reproduce, adapt, transmit, perform and display such modification in 
connection with the provision of such Development Services and for no other 
purpose without NETSCAPE's prior written approval. In the event that ADFORCE 
desires to integrate such modification in the Technology and obtains 
NETSCAPE's approval thereto, then ADFORCE shall reimburse NETSCAPE for any 
payment made by NETSCAPE for such Development Services, or waive such payment 
by NETSCAPE, in consideration for the grant of such license to ADFORCE. 
ADFORCE may exercise its rights under the foregoing license through Personnel 
who are obligated by written agreement to maintain such modification in 
confidence and restrict their use of such modification pursuant to terms 
comparable to those set forth in Article 13.

          (c)  ADFORCE shall have valid and enforceable written agreements 
with all of its Personnel providing Development Services hereunder containing 
confidentiality and nondisclosure obligations comparable in scope to those 
set forth in Article 13 and giving ADFORCE all rights and authority necessary 
to effectuate the provisions of this Section 5.4.  ADFORCE shall provide 
copies of these agreements to NETSCAPE upon NETSCAPE's request.

          (d)  To the extent that ADFORCE delivers to NETSCAPE any 
Improvements, designs, drawings, specifications, documentation, computer 
software, reports, training materials, inventions, discoveries and other 
items that are not Work Products, such items shall be deemed included in the 
Technology and licensed pursuant to Section 2.1 above.

      5.5  CHANGE MANAGEMENT PROCESS.  Notwithstanding the foregoing 
provisions of this Article 5, if NETSCAPE implements a version of the 
Technology containing any modification to the source code for the Software 
that adds a substantially new feature or function to the version of the 
Technology used by ADFORCE (in contrast to merely correcting what are 
colloquially known as "bugs" in such Software or making any other minor 
modification to an existing feature or function) then: (a) ADFORCE shall not 
be obligated to provide Development Services or Technical Support Services 
for such Improvement; and (b) in the event that NETSCAPE does not request, or 
ADFORCE does

not agree to provide, such Services, the Parties shall work together to 
devise a change management process to facilitate the technical support and 
maintenance of NETSCAPE's version of the Technology containing such 
Improvement.

shall provide the Ad Serving Services requested by NETSCAPE for no additional 
consideration other than reimbursement of the Fully Burdened Costs of the 
provision by ADFORCE Personnel of such Ad Serving Services; provided, 
however, that in the event that ADFORCE agrees to provide any Ad Serving 
Services to any Third Party that is similarly situated to NETSCAPE at a rate
that is more favorable to such Third Party than the consideration payable
by NETSCAPE under this subpart (a), then ADFORCE shall provide the Ad Serving
Services requested by NETSCAPE at such Third Party's rate.

          (b)  If, at any time prior to July 15, 1999 any Ad Serving Services 
are required to be performed by ADFORCE hereunder and (i) the parties have

Serving Services provided for in Section 6.2 above, NETSCAPE shall reimburse the
following costs incurred by ADFORCE in the provision of Ad Serving Services
requested by NETSCAPE for the purposes set forth in Section 6.1 above, and, at
NETSCAPE'S option, NETSCAPE shall provide financing for such costs on mutually
agreeable terms, but in any event on terms no less favorable than such terms are
commercially available to entities similarly situated.

          (a)  Reimbursement for ADFORCE's incremental costs for any
               modification of the AdForce System required to meet NETSCAPE's
               needs for the provision of Ad Serving Services (other than
               capitalized costs, which if financed at the time such costs are
               incurred, shall be reimbursed at the time such costs are
               amortized), excluding any modifications required to scale the
               Software or other Technology to meet NETSCAPE's needs;

          (b)  Reimbursement for ADFORCE'S incremental costs for any additional
               equipment that ADFORCE must purchase or lease solely to meet
               NETSCAPE's needs for the provision of Ad Serving Services for so
               long as necessary to meet NETSCAPE's needs; and

          (c)  Reimbursement for any additional incremental bandwith costs
               incurred by ADFORCE solely in connection with the provision of Ad
               Serving Services to NETSCAPE.

                              NETSCAPE MARKETING EFFORTS

     7.1  NETSCAPE MARKETING EFFORTS.  NETSCAPE shall use commercially
reasonable efforts to encourage NETSCAPE Partners (but NETSCAPE shall not be
obligated to actively solicit NETSCAPE Partners) to use the AdForce System for
the serving and management of Internet advertisements, subject to agreement
between ADFORCE and such NETSCAPE Partners on the terms and conditions of such
use.

     7.2  COMMISSIONS.  If, as a result of marketing efforts by NETSCAPE, a
NETSCAPE Partner or any other Person enters into an agreement with ADFORCE to

utilize the AdForce System, then, provided that, as of the time that ADFORCE
enters into such agreement with such NETSCAPE Partner or other Person, the
Parties have executed a Demographic Data Agreement, NETSCAPE is in compliance
with all of its material obligations thereunder and does not Materially Limit or
Prohibit the use by ADFORCE of Demographic Data, ADFORCE shall pay to NETSCAPE
on a quarterly basis the following commissions on the gross amount of the
consideration charged by ADFORCE to such NETSCAPE Partner or other Person for
use of the ADFORCE AdForce System:

          (a)  For the first year of such agreement, the greater of 4% and the
               highest percentage commission granted by ADFORCE at such time to
               any employee or agent of ADFORCE or to any Third Party for
               similar marketing or sales efforts; and

          (b)  For each succeeding year of such agreement, the greater of 2% and
               the highest percentage commission granted by ADFORCE at such
               time to any employee or agent of ADFORCE or to any Third Party
               for similar marketing or sales efforts.

     7.3  COMMISSION SHARING.  Notwithstanding the provisions of Section 7.2
above, if NETSCAPE and any employee or agent of ADFORCE or any other Third Party
claims commissions with respect to the same Person (and such Person has not
entered into an agreement with ADFORCE solely as a result of NETSCAPE marketing
efforts), ADFORCE shall not be required to pay total commissions to NETSCAPE and
such Third Party in excess of the amount specified in Section 7.2 and ADFORCE
may apportion the applicable commission specified in Section 7.2 between
NETSCAPE and the Third Party in such manner as ADFORCE determines in good faith
to be equitable.

     9.1  PAYMENT PROCEDURES.

          (a)  Unless otherwise agreed to in writing by the Parties, all
payments due by NETSCAPE for the provision of Services by ADFORCE hereunder
shall be due and payable thirty (30) days after the receipt by NETSCAPE of a
proper invoice therefor from ADFORCE, which invoice shall include such detail
and supporting documentation as NETSCAPE may reasonably request. Notwithstanding
the foregoing, NETSCAPE agrees to pay to ADFORCE the amount set forth in Exhibit

Effective Date, which represents a prepayment of the estimated fees for Ad
Serving Services for the Initial Ad Serving Services Term ("Prepayment").

The Prepayment shall be credited against the Ad Serving Service fees accruing 
under this Agreement during the Initial Term, which ADFORCE shall calculate 
monthly in accordance with Exhibits B and C and submit to NETSCAPE for its 
review and approval.  For each $1.00 of fees due up to the Prepayment, $1.00 
shall be credited against the Prepayment.  Upon exhaustion of the Prepayment, 
ADFORCE shall invoice NETSCAPE monthly in arrears for the Ad Serving Services 
provided to NETSCAPE based on the rates for such Services as set forth in 
Exhibit B.

Each month and coincident with the impression forecast NETSCAPE will provide per
Exhibit A, Section 1(C), the Parties will review the estimates that form the
basis of the prepayment described in Exhibit B and discuss any adjustments to
the forecast, principally the impression forecast and the headcount forecast.
Unless the parties mutually agree otherwise, if the changes to the forecasts in
Exhibit C are estimated to have a sum total impact greater than 10% on the fees
(as measured against the prior adjustment to fees), the Parties will make a
mutually agreed to adjustment in the fees going forward.

On or before August 1, 1999, the Parties will evaluate if there is a significant
change in the payment forecast for the remainder of the term.  If there is a
significant decline in the forecast (greater than 30%), ADFORCE will make an
adjusting refund at that time, including interest on the amount of the refund
equal to the lower of (i) the prime rate on August 1, 1999 or (ii) the maximum
amount permitted by law.

If Netscape opts to deploy ADFORCE's Banner Exchange technology to provide a
Banner Exchange to NETSCAPE Banner Exchange Partner sites outside of NETSCAPE
Netcenter or NETSCAPE Affiliates, NETSCAPE may do so solely on a "barter" basis
as described in the Banner Exchange definition above.  For ads served by
NETSCAPE to such external sites, NETSCAPE will make additional payments to
ADFORCE based on a CPM rate equal to 50% of NETSCAPE's imputed CPM at the end of
the Initial Term or a $0.04 CPM, whichever is higher, provided that the rate
shall never exceed the lowest CPM rate ADFORCE is offering other banner exchange
customers.  NETSCAPE shall make these payments for as long as it requests the
delivery of improvements to ADFORCE's Banner Exchange technology or a minimum of
two years after NETSCAPE first deploys ADFORCE's Banner Exchange technology,
whichever is greater.

          (b)  Unless otherwise agreed to in writing by the Parties:  (i) all 
payments due by ADFORCE under Article 7 in connection with ADFORCE's entrance 
into an agreement for use of the AdForce System with an NETSCAPE Partner or 
other Person as a result of NETSCAPE marketing efforts shall be paid to 
NETSCAPE within sixty (60) days after the end of the calendar quarter during 
which such agreement is entered into and within sixty (60) days after the end 
of each succeeding calendar quarter thereafter.

          (c)  All payments due to the payee Party hereunder shall be paid to
the payee Party in U.S. Dollars by wire transfer, or by such other method
mutually agreed upon by the Parties, in each case at the expense of the payor
Party, for value no later than the due date thereof (with 24 hours advance
notice of each wire transfer) to such bank account or accounts as the payee
Party shall designate in writing within a reasonable period of time prior to
such due date.

     9.2  LATE PAYMENT.  Without limiting the payee Party's rights to pursue any
other remedies at law or in equity, if the payor Party fails to pay any payment
required under this Agreement thirty days after written notice of past due
amount, then the payor Party shall pay annually compounded interest on such
amount at an annual rate equal to the lower of (a) the highest rate permitted by
applicable law and (b) the lowest prime rate as published by The Wall Street 
Journal on or nearest to such due date plus three percent (3%), which interest
shall accrue from the date the payment not timely made became due until the date
such payment is paid in full.

     9.3  APPLICATION OF PAYMENTS.  Any payments received by the payee Party
shall be applied first to the satisfaction of the oldest of any unpaid, accrued
interest charges and, following payment of all such interest charges, to the
satisfaction of the oldest of any unpaid fees or other amounts due hereunder.

     9.4  TAXES.

          (a)  All payments required to be made by the payor Party under this
Agreement shall be made free and clear of, and without deduction for, any and
all taxes that are levied on the transfer of such payments to the payee Party.
If any withholding or deductions are required by applicable law, payments shall
be made such that, after such withholding or deductions, the net amount that the
payee Party received is equal to the amount due hereunder.  The payor Party
shall file any information or tax returns with respect to such taxes, and the
payor Party shall indemnify the payee Party from any interest or other payments,
fines or penalties relating to or resulting from any failure, delay or error of
the payor Party in doing so.

          (b)  ADFORCE shall be responsible for the payment of any and all
transfer, sales, use or similar taxes that are levied on or in connection with
the transfer of the Technology to NETSCAPE, including any Improvements.

     9.5  BOOKS AND RECORDS.  ADFORCE shall keep full, true and accurate books 
of account containing all particulars and reasonable supporting documentation, 
in connection with the provision of Services hereunder and the determination of
any amounts payable to NETSCAPE under Article 7.  All such books of account and
reasonable supporting documentation shall be located at the principal place of
business of ADFORCE and shall be open for inspection by NETSCAPE or any
independent certified public accountant retained by NETSCAPE, at a time mutually
acceptable to the Parties during normal business hours but no more frequently
than once each calendar year for three years

following the end of the calendar year to which they pertain (and access shall
not be denied thereafter if reasonably available).  If such records are
insufficient or any such inspection discloses a discrepancy in favor of NETSCAPE
of five percent (5%) or more of the amounts actually due for any period, then,
in addition to any other rights and remedies available to NETSCAPE under this
Agreement, ADFORCE shall pay or refund to NETSCAPE the amount of such
discrepancy as well as the reasonable cost of such inspection promptly following
ADFORCE's receipt from NETSCAPE of the bill or invoice for such inspection.

               for such Party's execution, delivery and performance of this
               Agreement or consummation of the transactions contemplated

     10.2  ADDITIONAL REPRESENTATIONS AND WARRANTIES OF ADFORCE. ADFORCE 
further represents and warrants to NETSCAPE that:

           (a)  WORKMANLIKE SERVICES. The Services shall be provided in a 
                workmanlike manner, in accordance with the standards of care 
                and diligence and the level of skill, knowledge and judgment 
                normally practiced by nationally-recognized information 
                technology services firms in performing services of a similar 
                nature;

           (b)  NONINFRINGEMENT.  The Technology does not, and any 
                Improvements provided by ADFORCE, any Work Products and 
                NETSCAPE's use of the Technology and Work Products as 
                authorized herein shall not, infringe any copyright, trade 
                secret or other proprietary rights (except patent rights) of 
                any Third Party or otherwise conflict with the rights of any 
                Third Party, and, to the best of ADFORCES's knowledge, the 
                Technology does not, and any Improvements provided by 
                ADFORCE, any Work Products and NETSCAPE's use of the 
                Technology and Work Products shall not, infringe any patent 
                of any Third Party;

           (c)  NO LITIGATION.  There is no action, suit, proceeding or 
                arbitration pending, and, to the best of ADFORCE's knowledge, 
                there is no action, suit, proceeding, arbitration or claim 
                threatened, concerning the Technology;

           (d)  NO LIENS OR ENCUMBRANCES.  The Technology is free from any 
                security interests and other liens and encumbrances of Third 
                Parties arising from the actions or inaction of ADFORCE;

           (e)  NO UNAUTHORIZED CODE.  The Technology does not, and any 
                Improvements provided by ADFORCE shall not, contain any back 
                door, time bomb, drop dead device, protect codes, data 
                destruct keys, or other software routine designed to disable 
                a computer program automatically with the passage of time or 
                under the control of any Person other than NETSCAPE. To the 
                best of ADFORCE's knowledge, the Technology does not, and any 
                Improvements provided by ADFORCE shall not, contain any 
                virus, Trojan horse, worm or other software routine designed 
                to permit unauthorized access or to disable, erase, modify, 
                deactivate or otherwise harm software, hardware or data; and 
                ADFORCE covenants that, prior to or at the time of the 
                delivery of any Technology (including any Improvement), 
                ADFORCE shall test the Technology using a current version of 
                a reputable "antivirus" program and remove any such 
                unauthorized codes; and

           (f)  YEAR 2000 COMPLIANCE.  All Software and other operational 
                items included in the Technology shall: (i) properly execute 
                with all date data, whether from years in the same century or 
                different centuries, including by yielding correct results 
                in arithmetic operations, comparisons and sorting of date 
                fields and in leap year calculations; and (ii) not abnormally 
                cease to execute or return an error message due to 
                date-related processing.

     10.3  NO OTHER WARRANTIES.  THE EXPRESS WARRANTIES IN THIS AGREEMENT 
SHALL BE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE 
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

                               ARTICLE 11
                            INDEMNIFICATION

     11.1  INDEMNITY.  NETSCAPE shall not be liable to ADFORCE, any of its 
Affiliates or any other Person for, and ADFORCE shall indemnify and hold 
harmless NETSCAPE and all NETSCAPE Affiliates, and their respective 
directors, officers, employees and agents (collectively, the "NETSCAPE 
Indemnitees"), from and against any Losses incurred arising out of or 
resulting from: (a) any infringement of any patent, copyright, trade secret 
or other proprietary right by the Technology or any Work Product, except to 
the extent that such infringement arises solely from any Improvement 
developed by NETSCAPE, or by ADFORCE to NETSCAPE's specifications if ADFORCE 
could not reasonably have conformed to such specifications while avoiding the 
infringement; or (b) the presence of ADFORCE's employees or agents on the 
premises of NETSCAPE or an NETSCAPE Affiliate (except those Losses that 
result solely from the gross negligence or willful misconduct of NETSCAPE or 
a NETSCAPE Affiliate), including, but not limited to, Losses resulting from 
injuries to ADFORCE's Personnel and Losses resulting from injuries caused by 
ADFORCE's Personnel.

     11.2  PROCEDURE.  Any NETSCAPE Indemnitee shall notify ADFORCE promptly 
in writing of an indemnifiable claim or cause of action under Section 11.1 
above upon receiving notice or being informed of the existence thereof; 
provided, however, that failure to notify ADFORCE of an indemnifiable claim 
or cause of action shall not relieve ADFORCE of its obligation to provide 
indemnification hereunder, except to the extent that such failure prejudices 
ADFORCE's ability to defend or settle such claim or cause of action. ADFORCE 
shall assume, at its cost and expense, the sole defense of such claim or cause 
of action through counsel selected by ADFORCE and reasonably acceptable to 
NETSCAPE, except that in the case of a conflict of interest between ADFORCE 
and NETSCAPE, ADFORCE shall, at ADFORCE's cost and expense, provide separate 
counsel for NETSCAPE selected by NETSCAPE. ADFORCE shall maintain control of 
such defense, including any decision as to settlement; provided that, in the 
event that


                                    20

<PAGE>

                                                                  CONFIDENTIAL

ADFORCE does not maintain control of such defense on a timely basis, then, 
without prejudice to any other rights and remedies available to NETSCAPE 
under this Agreement, NETSCAPE may take over such defense with counsel of its 
choosing, at ADFORCE's cost and expense. NETSCAPE may, at its option and 
expense, participate in ADFORCE's defense, and if NETSCAPE so participates, 
the Parties shall cooperate with one another in such defense. ADFORCE shall 
bear the total costs of any court award or any settlement of such claim or 
cause of action approved by ADFORCE and all other costs, fees and expenses 
related to the resolution thereof (including reasonable attorneys' fees, 
except for attorneys' fees for which NETSCAPE is responsible in the event 
that NETSCAPE participates in ADFORCE's defense of such claim or cause of 
action).

     11.3  ABATEMENT OF INFRINGEMENT.  If ADFORCE reasonably believes it 
necessary to do so to minimize its liability under Section 11.1 above, 
ADFORCE may, at its expense, procure the right for NETSCAPE to continue using 
the Technology or any Work Product, replace the Technology or any Work 
Product with a functionally equivalent noninfringing item, or modify the 
Technology or any Work Product so that it is functionally equivalent but 
noninfringing.

                            ARTICLE 12
                      LIMITATION ON LIABILITY

     NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY HEREUNDER FOR ANY 
INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES.

                            ARTICLE 13
                         CONFIDENTIALITY

     13.1 CONFIDENTIALITY OBLIGATION.  Each of NETSCAPE and ADFORCE (the 
"Receiving Party") shall keep, and shall cause their Affiliates to keep, 
strictly confidential any information disclosed by the other Party (the 
"Disclosing Party") or otherwise made available to the Receiving Party 
concerning the Technology or either Party's performance of this Agreement or 
otherwise concerning the business, operations, trade secrets or other 
proprietary information of the Disclosing Party (whether in written media or 
otherwise) ("Confidential Information"), using the same degree of care that 
it uses to protect its own confidential or proprietary information of a like 
nature but in no event less than a reasonable degree of care.  "Confidential 
Information" shall not include information: (a) which is or becomes generally 
available to the public other than as a result of disclosure thereof by the 
Receiving Party; (b) which is lawfully received by the Receiving Party on 
a nonconfidential basis from a Third Party that is not itself under any 
obligation of confidentiality or nondisclosure to the Disclosing Party or any 
other Person with respect to such information; (c) which is independently 
developed by the Receiving Party; or (d) which was in the Receiving Party's  
possession prior to receipt from the Disclosing Party. Each Party shall 
treat any Technology or Work Product owned by or assigned to the other Party 
as Confidential Information of such Party.


                                 21

<PAGE>

                                                                  CONFIDENTIAL

     13.2  NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Receiving Party 
shall use Confidential Information solely for the purposes of this Agreement 
and shall not disclose or disseminate any Confidential Information to any 
Person at any time, except for disclosure to its Affiliates and to those of 
its own and its Affiliates' directors, officers, employees, accountants, 
attorneys, advisers and agents whose duties reasonably require them to have 
access to such Confidential Information, provided that such directors, 
officers, employees, accountants, attorneys, advisers and agents are bound 
to maintain the confidentiality of such Confidential Information to the same 
extent as if they were Parties hereto.

     13.3  EXCEPTION.  The foregoing confidentiality and nondisclosure 
obligations shall not apply to Confidential Information: (a) incidentally 
retained in the memory of Persons to whom the Receiving Party is permitted 
to disclose Confidential Information, other than as the result of an 
intentional effort to commit Confidential Information to memory to circumvent 
the provisions of this Article 13; or (b) which is required to be publicly 
disclosed by law or by regulation; provided, however, that, in such event, 
the Receiving Party provides the Disclosing Party with prompt advance notice 
of such disclosure so that the Disclosing Party has the opportunity if it so 
desires to seek a protective order or other appropriate remedy.

     13.4  SURVIVAL.  The confidentiality and nondisclosure obligations of 
this Article 13 shall remain in effect for three years following the date 
hereof or two years following the termination of this Agreement, whichever is 
greater, except with respect to source code and related source code 
documentation, for which the obligations of this Article 13 shall survive for 
so long as the source code and documentation remain Confidential Information.

     13.5  SOURCE CODE PROTECTION.  The Receiving Party shall protect 
Confidential Information consisting of source code and related source code 
documentation from unauthorized use and disclosure to the same extent that it 
protects its own source code (but no less than to a reasonable degree).

     13.6  OTHER BUSINESS ACTIVITIES.

           (a)  The Disclosing Party agrees that the Receiving Party may 
currently or in the future acquire information, either independently 
developed or legally received from Third Parties, which may be similar to the 
Confidential Information. Nothing in this Agreement shall be construed as a 
representation that the Receiving Party does not or shall not have such 
independently developed or legally received information.

           (b)  Nothing in this Agreement shall be construed as a 
representation or agreement to restrict reassignment of the Receiving Party's 
employees, or in any manner to affect or limit either Party's present or 
future business activities of any nature, including business activities which 
could be competitive with the Disclosing Party.

           (c)  Nothing in this Agreement shall be construed as a 
representation or agreement that the Receiving Party shall not develop or have 
developed for it products, concepts, systems or techniques contemplated by or 
embodied in the Confidential Information, provided that the Receiving Party 
does not violate any of its obligations under this Agreement in connection 
with such development.

                              ARTICLE 14
                         TERM AND TERMINATION

     14.1  TERM.

           14.1.1 TECHNOLOGY LICENSE TERM.  Provided the license grant to 
NETSCAPE pursuant to Section 2.1(a) becomes effective, this Agreement with 
respect to such Technology license grant and related provisions herein shall 
commence as of the Effective Date and, unless terminated in accordance with 
the provisions of Section 14.2 below, shall remain in full force and effect 
without expiration.

           14.1.2 TECHNOLOGY LICENSE GRANTED BY DEFAULT TERM.  If the license 
grant to NETSCAPE does not become effective pursuant to Section 2.1(a) but 
Netscape obtains access to ADFORCE's source and object code as a result of 
ADFORCE's default hereunder as described in such Section 2.1 (a), then this 
Agreement with respect to such license grant and related provisions herein 
shall commence as of the Effective Date and remain in full force and effect 
through the date NETSCAPE's one-year right to use said source and object code 
expires.

           14.1.3 AD SERVING SERVICES TERM.  The term of this Agreement with 
respect to the Ad Serving Services and related provisions herein shall 
commence as of the Effective Date and remain in full force and effect through 
November 22, 1999. If both Parties assent in writing prior to the expiration 
of this Agreement, this Agreement with respect to such Ad Serving Services 
will renew on the same terms and conditions for an additional one year period.

     14.2  TERMINATION.

           14.2.1  TERMINATION RIGHTS OF NETSCAPE.  NETSCAPE shall have the 
right to terminate this Agreement in the event of the breach by ADFORCE of, 
or the failure of ADFORCE to perform, any of its material obligations 
hereunder and the failure to remedy such breach or nonperformance with sixty 
(60) days following the receipt of written notice of such breach or 
nonperformance from NETSCAPE. Such termination shall be immediately effective 
upon the receipt by ADFORCE of written notice of termination from NETSCAPE. 
On expiration or termination of this Agreement for any reason, the parties 
agree to work in good faith to ensure a smooth transition of the Service and 
Technology (if applicable) to NETSCAPE within 60 days of such termination or 
expiration date.

           14.2.2 TERMINATION RIGHTS OF ADFORCE. ADFORCE shall have the right 
to terminate this Agreement in the event of:

                (a)     The breach by NETSCAPE of, or the failure of NETSCAPE 
                        to perform, any of its material obligations under 
                        this Agreement (except for its obligations under 
                        Articles 3, 4, 5 and 6 above) and the failure to 
                        remedy such breach or nonperformance within sixty 
                        (60) days following the receipt of written notice of 
                        such breach or nonperformance from ADFORCE; or

                (b)     A "Data Agreement Material Breach" by NETSCAPE. For 
                        purposes of this Agreement, a "Data Agreement Material
                        Breach" means the breach by NETSCAPE of, or the 
                        failure of NETSCAPE to perform, any of its material 
                        obligations under the Demographic Data Agreement, the 
                        failure of NETSCAPE to remedy such breach or 
                        nonperformance within sixty (60) days following the 
                        receipt of written notice of such breach or 
                        nonperformance from ADFORCE, and, in the event that 
                        such breach or nonperformance is disputed by the 
                        Parties, the final determination of such breach or 
                        nonperformance by a court of competent jurisdiction 
                        from which no further appeal may be taken.

Such termination shall be immediately effective upon the receipt by NETSCAPE 
of written notice of termination from ADFORCE.

           14.2.3  ADFORCE RIGHT TO DISCONTINUE SERVICES. ADFORCE shall have 
the right to discontinue the provision of Services pursuant to Sections 3.2, 
4.1, 5.1 and 6.1 above for which it is entitled to reimbursement or other 
payment from NETSCAPE, but shall not have the right to terminate this 
Agreement or the licenses granted pursuant to Section 2.1(a) above, if 
effective, in the event of the material breach by NETSCAPE of its obligation 
hereunder to reimburse or pay ADFORCE for any Services and the failure to 
remedy such breach within sixty (60) days following the receipt of written 
notice of such breach from ADFORCE. Such discontinuation of Services shall be 
immediately effective upon the receipt by NETSCAPE of written notice of 
discontinuation from ADFORCE. On expiration or termination of this Agreement 
for any reason, the parties agree to work in good faith to ensure a smooth 
transition of the Service and Technology (if applicable) to NETSCAPE within 
60 days of such termination or expiration date.

     14.3  EFFECT OF TERMINATION. Provided the license grant to NETSCAPE 
under Section 2.1(a) becomes effective, and notwithstanding anything herein 
to the contrary, in the event of the termination of this Agreement other than 
upon the breach by NETSCAPE of any of its material obligations under Article 
2 or Article 13 and the failure to remedy

such breach within the time period set forth in Section 14.2.2 above, 
NETSCAPE shall have the right, for a period of one year following 
termination, to continue to exercise all license rights granted to it under 
Section 2.1 above on all the same terms in effect pursuant to this Agreement 
immediately prior to termination and to retain any Confidential Information 
necessary or useful for the exercise of such rights. Notwithstanding anything 
herein to the contrary, ADFORCE shall in no event be entitled to enjoin or 
seek to enjoin any exercise by NETSCAPE of the rights set forth in this 
Section 14.3, and ADFORCE hereby expressly waives any right to injunctive or 
other equitable relief, whether based on statute, common law or otherwise, 
arising out of any alleged default by NETSCAPE that would adversely affect 
the exercise by NETSCAPE of its rights under this Section 14.3.

     14.4  RETURN OF CONFIDENTIAL INFORMATION. Within thirty (30) 
calendar days following the termination of this Agreement other than 
termination where Section 14.3 above would be applicable, each Party shall 
either deliver to the other Party, or destroy, all copies of any Confidential 
Information of the other Party embodied in a tangible medium that is in such 
Party's possession or under its control, and shall furnish to the other Party 
an affidavit signed by an officer of such Party certifying that, to the best 
of its knowledge, such delivery or destruction has been fully effected.

     14.5  SURVIVAL. All rights granted to and obligations undertaken by 
the Parties hereunder shall terminate immediately upon the termination of 
this Agreement, except for the rights and obligations provided for in 
Sections 14.3 and 14.4 above as well as the following rights and obligations, 
which shall survive according to their terms:

               (a)   The obligation of the payor Party to pay any and all 
                     payments accrued hereunder;

               (b)   The license to ADFORCE granted in Section 5.4;

               (c)   The right of NETSCAPE to inspect the books and records 
                     of ADFORCE to the extent provided in Section 9.5;

               (d)   The indemnification obligations of Article 11 and the 
                     limitation on liability of Article 12;

               (e)   The confidentiality and nondisclosure obligations of 
                     Article 13; and 

               (f)   The provisions of Sections 15.1, 15.7, 15.8, 15.10, 
                     15.19, and 15.20 below.

In addition, termination of this Agreement shall not affect the remedies of 
the Parties otherwise available at law or in equity in relation to any rights 
accrued under this Agreement prior to termination.

     15.1  ELECTRONIC REPOSSESSION. In no event shall ADFORCE 
electronically repossess, de-install, deactivate or disable any Technology in 
the absence of a final, unappealable judgment of a court of competent 
jurisdiction that the license rights granted under Section 2.1 above have 
been validly terminated.

     15.2   PERIODIC DISCUSSIONS. Commencing within thirty (30) days 
following the execution of this Agreement and on a quarterly basis 
thereafter, NETSCAPE shall engage in discussions with ADFORCE concerning 
NETSCAPE's deployment of the Technology and shall endeavor to provide ADFORCE 
with non-binding, 180 day forecasts of the Services that NETSCAPE intends to 
request from ADFORCE hereunder. Within forty-five (45) days after the 
Deployment Date, the Parties shall execute a more detailed development, 
support and maintenance agreement with respect to ADFORCE's obligations to 
provide development, support and maintenance for the Technology, including, 
without limitation, ADFORCE's obligations for the delivery of Improvements 
and other Technology, ADFORCE's obligations to provide Development Services 
and Technical Services, and ADFORCE's obligations to cure any nonperformance 
or other failure with respect to the Technology.

     15.3   MUTUAL NON-SOLICITATION. For a period of one year following 
the date hereof, without the prior written approval of the other Party, 
neither Party or any of its Affiliates shall actively solicit for hire any 
Personnel of the other Party with responsibility for the development or 
maintenance of the Technology or Work Products or for the provision of 
interactive advertisement serving, trafficking, targeting or related 
services, excluding independent contractors that do not spend the majority of 
their time providing services to such Party. The foregoing mutual 
non-solicitation covenant shall terminate at any time in the event of the 
acquisition by a Third Party of more than fifty percent (50%) of the voting 
power of ADFORCE, the acquisition by a Third Party of all or substantially all 
of the assets of ADFORCE, or the consummation of a merger, consolidation or 
similar corporate transaction of ADFORCE with or into a Third Party where the 
voting securities of ADFORCE outstanding immediately prior to consummation of 
such transaction are converted into cash or securities possessing less than 
fifty percent (50%) of the voting power of the surviving entity. The 
obligations of the Parties under this Section 15.3 shall not survive the 
termination of this Agreement.

     15.4   FAILURE TO ASSERT RIGHTS IN BANKRUPTCY. NETSCAPE's failure to 
assert its rights to retain its benefits under this Agreement in accordance 
with 11 U.S.C. Section 365(n)(1)(B) shall not be construed as a termination 
of this Agreement by NETSCAPE under 11 U.S.C. Section 365(n)(1)(A).

     15.5   FURTHER ASSURANCES. Upon the request of either Party, the 
other Party shall sign and deliver any assignments or other necessary 
documents and otherwise assist the requesting Party to obtain, maintain, 
perfect or enforce any of the requesting Party's rights hereunder.

venture relationship between the Parties hereto.

of the State of California applicable to contracts made and to be performed 
entirely within such jurisdiction and without giving effect to the choice 
or conflict of laws rules or principles of the State of California or of any 
other jurisdiction.

     15.8   CONSENT TO JURISDICTION. Each of the Parties irrevocably 
submits to the exclusive jurisdiction of the courts of the State of California 
and of any United States federal court sitting in the State of California in 
any action or proceeding arising out of or relating to this Agreement, and 
irrevocably agrees that all claims in respect of such action or proceeding 
shall be heard and determined in any such California or United States federal 
court. Each Party further agrees that service of any process, summons, notice 
or document by registered mail to the address of such Party set forth in

proceeding brought against such Party in any such court. Each Party hereby 
irrevocably and unconditionally waives any objection to the laying of venue 
of any action or proceeding arising out of or relating to this Agreement in 
any such court and further irrevocably and unconditionally waives and agrees 
not to plead or claim in any such court that any such action or proceeding 
brought in any such court has been brought in any inconvenient forum. Each 
Party further agrees that a final, nonappealable judgment in any such action 
or proceeding shall be conclusive and may be enforced in any other 
jurisdictions by suit on the judgment or in any other manner provided by law.

     15.9   COUNTERPARTS. This Agreement may be executed in any number of 
counterparts and may be executed by facsimile. All counterparts shall

     15.11  FORCE MAJEURE. If any circumstance beyond the reasonable 
control of either Party occurs which delays or renders impossible the 
performance of that Party's obligations under this Agreement on the dates 
herein provided, such obligation shall be postponed for such time as such 
performance necessarily has had to be suspended or delayed on account 
thereof, provided such Party shall notify the other Party in writing as soon 
as practicable, but in no event more than ten days after the occurrence of 
such force majeure. In such event, the Parties shall meet promptly to 
determine an equitable solution to the effects of any such event, provided 
that such Party who fails because of force majeure to perform its obligations 
hereunder shall upon the cessation of the force majeure take all reasonable 
steps within its power to resume with the least possible delay compliance 
with its obligations. Events of force majeure shall include, without 
limitation, war, revolution, invasion, insurrection, riots, mob violence, 
sabotage or other civil disorders, acts of God,

limitations imposed by exchange control regulations or foreign investment 
regulations or similar regulations, laws, regulations or rules of any 
government or governmental agency, and any inordinate and unanticipated 
delays in the regulatory review or governmental approval process that are 
within the control of such government or governmental agency. In no event 
shall the failure or nonperformance of the Technology as described in Section 
4.3 above constitute an event of force majeure.

     15.12  BINDING EFFECT; ASSIGNMENT.  This Agreement may not be 
assigned, in whole or in part, by either Party without the prior written 
consent of the other Party, except that: (a) NETSCAPE may assign any of its 
rights or obligations hereunder to America Online, Inc. or a wholly-owned 
subsidiary of NETSCAPE without ADFORCES's consent; and (b) the rights and 
obligations of either Party under this Agreement may be assigned without the 
other Party's consent to a Third Party acquiring all or substantially all of 
the assets of the assigning Party or to the surviving entity upon the 
consummation of any merger, consolidation or similar corporate transaction of 
the assigning Party with or into a Third Party. Any attempted assignment by 
either Party without the consent of the other Party in any circumstances 
other than those described in the immediately preceding sentence shall be 
null and void. This Agreement shall inure to the benefit of and be binding 
upon each of the Parties hereto and their respective successors and permitted 
assigns.

     15.13  ENTIRE AGREEMENT.  The terms and conditions herein contained 
constitute the entire agreement between the Parties relating to the subject 
matter of this Agreement and shall supersede all previous communications 
between the Parties with respect to the subject matter of this Agreement, 
except for the Confidential Non-Disclosure Agreement between the Parties 
dated as of January 1, 1999, and attached hereto as Exhibit D, each of which 
shall survive according to their terms. Neither Party has entered into this 
Agreement in reliance upon any representation, warranty, covenant or 
undertaking of the other Party that is not set out or referred to in this 
Agreement.

     15.14  RECITALS.  The recitals set forth at the start of this 
Agreement and the terms and conditions incorporated in such recitals shall be 
deemed integral parts of this Agreement, and all references in this Agreement 
to this Agreement shall encompass such recitals and the terms and conditions 
incorporated in such recitals.

     15.15  AMENDMENT.  This Agreement may be varied, amended or extended 
only by the written agreement of the Parties through their duly authorized 
officers or representatives, specifically referring to this Agreement.

     15.16  SEVERABILITY.  In the event that any provision of this 
Agreement is held to be illegal, invalid or unenforceable in a final, 
unappealable order or judgment (each such provision, an "invalid 
provision"), then such provision shall be severed from this Agreement and 
shall be inoperative, and the Parties promptly shall negotiate in good faith 
a lawful, valid and enforceable provision that is as similar to the invalid 
provision as may

                                                                  CONFIDENTIAL

be possible, while the remaining provisions of this Agreement shall remain 
binding on the Parties hereto.

     15.17  HEADINGS.  The descriptive headings of the several articles 
and sections of this Agreement are inserted for convenience only and do not 
constitute a part of this Agreement.

     15.18  NO WAIVER OF RIGHTS.  No failure or delay on the part of 
either Party in the exercise of any power or right hereunder shall operate as 
a waiver thereof. No single or partial exercise of any right or power 
hereunder shall operate as a waiver of such right or of any other right or 
power. The waiver by either Party of a breach of any provision of this 
Agreement shall not operate or be construed as a waiver of any other or 
subsequent breach hereunder.

     15.19  REMEDIES CUMULATIVE; SPECIFIC PERFORMANCE.  All rights and 
remedies granted to either Party under this Agreement are cumulative and in 
addition to, and not in lieu of, any other rights or remedies otherwise 
available to such Party at law or in equity. The Parties agree that any 
breach by either Party of, or failure of either Party to perform, any 
obligation under this Agreement shall constitute immediate and irreparable 
damage to the other Party which cannot be fully and adequately compensated in 
money damages and that, in the event of such breach or failure, the other 
Party shall be entitled to injunctive relief and specific performance in 
addition to any other remedies to which it may be entitled at law or in 
equity.

     15.20  CONFIDENTIALITY OF AGREEMENT.  Each Party shall maintain the 
confidentiality of this Agreement and all provisions of this Agreement and, 
without the prior consent of the other Party, neither Party shall make any 
press release or other public announcement of or otherwise disclose this 
Agreement or any of its provisions to any Third Party (a) other than to its 
Affiliates and to its own and its Affiliates' directors, officers, employees, 
attorneys and accountants, and to the lead underwriter engaged by ADFORCE in 
connection with any offering of securities of ADFORCE, whose duties 
reasonably require familiarity with this Agreement, provided that such 
Persons (including any such lead underwriter) are bound to maintain the 
confidentiality of this Agreement, and (b) except for such disclosure as may 
be required by applicable law or regulation, in which case the disclosing 
Party shall provide the other Party with prompt advance notice of such 
disclosure so that the other Party has the opportunity if it so desires to 
seek a protective order or other appropriate remedy; provided that, in 
connection with any offering of securities of ADFORCE, ADFORCE shall provide 
in advance to NETSCAPE for review the form and content of any disclosure of 
this Agreement or any of its provisions that may be required by applicable 
law or regulation and, to the extent consistent with its disclosure 
obligations under applicable law, include such modifications to such 
disclosure as may be reasonably requested by NETSCAPE (except that ADFORCE 
may file this Agreement as an exhibit to its registration statement if it 
would constitute a "material agreement" under applicable law or regulation 
and ADFORCE shall use its reasonable best efforts to obtain confidential 
treatment of the portions of this Agreement that meet the SEC qualifications

for confidential treatment if so requested by NETSCAPE). The confidentiality 
obligations of this Section 15.20 would apply, inter alia, to any disclosure 
by ADFORCE of this Agreement or of any provisions of this Agreement to any 
customer or potential customer of ADFORCE and any such disclosure would 
constitute a breach of this Section 15.20. The Parties agree that any breach 
of the provisions of this Section 15.20 by either Party, including, without 
limitation, by any directors, officers or employees of such Party, would 
constitute a breach by such Party of a material obligation hereunder for 
which the other Party shall have the right, notwithstanding the provisions of 
Section 14.2 above, to immediately terminate this Agreement without allowance 
of any period to remedy such breach, such termination to be immediately 
effective upon the receipt by the breaching Party of written notice of 
termination from the nonbreaching Party.

     15.21  USAGE.  Wherever any provision of this Agreement uses the 
term "including" (or "includes"), such term shall be deemed to mean 
"including without limitation" and "including but not limited to" (or 
"includes without limitation" and "includes but is not limited to") 
regardless of whether the words "without limitation" or "but not limited to" 
actually follow the term "including" (or "includes").

     IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to 
be executed by their duly authorized officers as of the date first above 
written.

                                 EXHIBIT A

                             AD SERVING SERVICES

1. ADFORCE AD SERVING SERVICES.

     A. ADFORCE SERVICE DEFINITION.  The AdForce service ("AdForce Service") 
is a proprietary Internet advertising administration system that will allow 
NETSCAPE to manage advertising on its Internet properties. As part of the 
AdForce Service, ADFORCE will provide NETSCAPE the ADFORCE "client" 
("Client"), which NETSCAPE will use to (i) generate ad tags, (ii) schedule 
advertising to run in the online environments in which NETSCAPE places those 
ad tags, and (iii) generate reports on such advertising. In addition, ADFORCE 
will maintain a centralized ADFORCE server complex from which ADFORCE will 
electronically deliver advertising scheduled by NETSCAPE to the online 
environments containing the ad tags placed by NETSCAPE. The delivery of 
"Impressions," defined as the transmission of advertisements by ADFORCE to an 
ADFORCE ad tag, will be verified by monthly third-party audits of the 
AdForce Service, conducted by the Audit Bureau of Verification Services, Inc. 
or another third party of comparable reputation chosen by ADFORCE. The 
AdForce Service includes the targeting features and a suite of standard 
reports available in the ADFORCE system listed below.

     B. THE ADFORCE SERVICE.  The AdForce Service includes the functionality 
described in Section 1.A. above and as described below, with telephone client 
services support from the hours of 6 a.m. to 6 p.m., Pacific Standard Time, 
Monday-Friday, excluding major holidays. ADFORCE will also maintain 24 x 7 
level technical service support via phone, cell phone or pager. In addition, 
ADFORCE will provide up to four (4) days of account management support on 
site at NETSCAPE each calendar month at no charge; unused days will not carry 
over to subsequent calendar months. NETSCAPE may select the days and must 
provide ADFORCE five (5) business days advance notice. Any additional days of 
on-site training or support will be at a cost of $1,000 per day. The twelve 
(12) days of monthly on-site account support to be provided by ADFORCE will 
not include training for major ADFORCE releases, which will be provided to 
NETSCAPE separately at no cost.

     C. CERTAIN NETSCAPE OBLIGATIONS.  NETSCAPE agrees to implement the ad 
tags per the ADFORCE User Guide and Help documentation, and to use the 
ADFORCE Client to schedule advertising it wishes ADFORCE to serve onto 
NETSCAPE's Web sites. NETSCAPE confirms its commitment to use the AdForce 
Service and Technology to serve not less than ninety percent (90%) of the ad 
Impressions NETSCAPE controls on its NETSCAPE Netcenter online property, as 
measured beginning April 15, 1999. However, if ADFORCE fails for any period 
of time to meet its obligations under Sections 3.2, 4.3, 5.1, or 10.2 of the 
Agreement or Section 7 of Exhibit A, then NETSCAPE may at its option reduce 
its percentage commitment to a level NETSCAPE deems necessary until such time 
as ADFORCE has come back into compliance. NETSCAPE agrees to provide ADFORCE 
monthly volume forecasts of Impressions to be delivered using the AdForce 
Service; these forecasts will be provided no later than three (3) days prior 
to the beginning of each calendar month. NETSCAPE shall indemnify and hold 
harmless ADFORCE from any liability and damages and costs (including 
reasonable costs and attorney's fees) arising out of or relating to 
advertising placed by NETSCAPE using the AdForce Service, including, without 
limitation, content, libel, invasion of privacy, and rights of publicity.

                                                                  CONFIDENTIAL

7.  PERFORMANCE METRICS

The Parties will measure real-world performance using a standard vendor such 
as Keynote, Inverse Networks or another service mutually agreed upon. 
NETSCAPE will be liable for the cost of the auditing services, not to exceed 
$50,000. The ADFORCE system must provide:

A.  Average ad delivery availability: 99.98%, measured each calendar month, 
    with no scheduled downtime. This metric also includes tracking functions 
    such as impressions and click through counting. If the AdForce Service 
    fails to meet this target level of performance, in addition to the 
    response times referenced in Section 4.3, ADFORCE will provide NETSCAPE a 
    "make good" on any ads which did not serve during any downtime in excess 
    of the required availability metric (for example, if ad delivery is down 
    0.03% of a given calendar month, then AdForce's make good shall apply 
    only to the 0.01% excess over the required metric). Accordingly, AdForce 
    will serve free of charge a number of ads equal to twice the number of ads 
    not served during such excess downtime. Finally, failure by the AdForce 
    Service to meet this performance metric for any four consecutive months 
    shall, at NETSCAPE's option, constitute a breach of the Agreement.

B.  Administration system availability: 99.95%, less scheduled maintenance, 
    measured each calendar quarter, with no scheduled downtime during Pacific 
    Standard Time working hours (8 a.m.-6 p.m.). Maximum scheduled downtime in
    any given work week shall be 4 hours; measure also excludes monthly 
    rebuilding of summary tables, provided they are executed only during 
    weekend hours. Includes order entry/administration and reporting. Finally, 
    failure by the AdForce Service to meet this performance metric for any four
    consecutive months shall, at NETSCAPE's option, constitute a breach of the 
    Agreement.

C.  Single http-ad server delivery latency of no more than 2.5 seconds. This 
    requirement will not apply at times when the Keynote Business 40 Benchmark 
    Page latency is greater than three times its weekly average. Schedule for 
    regular weekly measurements to be mutually agreed upon.

D.  Multiple ad delivery (maximum 9 ad requests) latency of no more than 10 
    seconds. This requirement will not apply at times when the Keynote Business
    40 Benchmark Page latency is greater than three times its weekly average. 
    Schedule for regular weekly measurements to be mutually agreed upon.

                          FEES AND PAYMENT SCHEDULE

The current estimated obligation by NETSCAPE for the Initial Ad Serving 
Services Term of the Agreement is:

              FOR THE QUARTER BEGINNING:     THE ESTIMATE IS:
<S>                                          <C>
              February 1, 1999               $  776,159
              May 1, 1999                    $  778,133
              August 1, 1999                 $  866,529
              November 1, 1999               $  261,550
                                             ----------
              TOTAL:                         $2,692,372
</TABLE>

* The figure for the quarter beginning November 1, is a prorated amount based 
on the 22 days from November 1, 1999 until the end of the Initial Ad Serving 
Services Term.

NETSCAPE will pre-pay an amount equal to $2.7 million, per Section 9.1.

Based on NETSCAPE's current impression forecast, this converts to an imputed 
CPM rate as follows, and under no circumstances will NETSCAPE's CPM rate 
exceed ADFORCE's own audited allocated CPM cost for the same period (defined 
as ADFORCE's total cost of goods sold divided by ADFORCE's total 
impressions), unless NETSCAPE chooses to increase ADFORCE's headcount 
requirements:

<TABLE>
<CAPTION>
              FOR THE QUARTER BEGINNING:     THE CPM ESTIMATE IS:
<S>                                          <C>
              February 1, 1999               $0.10
              May 1, 1999                    $0.10
              August 1, 1999                 $0.10
              November 1, 1999               $0.08
</TABLE>

ADFORCE may use its audited allocation accounting methodology to bill 
NETSCAPE; however, this amount may not exceed the computation of direct 
obligations contained in Exhibit C, after updating Exhibit C for actual 
impressions, headcount and other calculations. Specifically, those updates 
will be made in an electronic version of Exhibit C, and the maximum 
obligation for any given quarter will be the sum of those calculations, which 
are described below.

1.  Actual impressions will be as measured and mutual agreed to by each party.

2.  Headcount:

- -   Estimates will be adjusted per Section 9.1. It is currently estimated 
    that there are 9 full-time-equivalents at ADFORCE working on the NETSCAPE 
    account. It is agreed that 6 of these headcount, covering operations and 
    account support, will not increase in number at any time. The three 
    remaining headcount will work on providing quality assurance for campaign 
    management, and this number could increase or decrease at NETSCAPE's 
    option, depending on how NETSCAPE organizes this work in the future.

- -   The formula for calculating headcount costs will be: [Number of headcount]
    multiplied by [$35,000] multiplied by [1.25 if before July 15, 1.40 if after
    July 15, 1999, or 1.0 if Section 6.2(a) controls]

                                      36
<PAGE>

                                                                  CONFIDENTIAL


3.  Facilities costs will be calculated according to the following formula: 
    [Number of headcount in 1 above] multiplied by [$5,000] multiplied by 
    [1.25 if before July 15, 1.40 if after July 15, 1999, or 1.0 if 
    Section 6.2(a) controls]

4.  G&A will not change from Exhibit C, unless mutually agreed upon

5.  Bandwidth will not change from Exhibit C, unless mutually agreed upon

6.  Amortized capital, equipment and related costs will be based on Exhibit 
    C. Specifically, the formula for any given quarter in which NETSCAPE is 
    using the ADFORCE Ad Serving Service equals the sum of [the capital 
    depreciation for capital expenses in that same quarter] and [the capital 
    depreciation for capital expenses in any previous quarter in which NETSCAPE
    used the ADFORCE Ad Serving Service where the depreciation schedule has not
    expired].

    (a) The initial calculations for any three-month quarter are:

        (1)  Small System units purchased in quarter = [[Average NETSCAPE 
             impressions served by ADFORCE per day] divided by [1,000,000] 
             multiplied by [0.83] less [the sum of the total number of Small 
             System units purchased in previous quarters]

        (2)  Small System units required in quarter = [Average NETSCAPE 
             impressions served by ADFORCE per day] divided by [1,000,000]
             multiplied by [0.83]

        (3)  Cost of Small System purchased in quarter = [total small system 
             units purchased in the quarter] multiplied by [$25,000]

        (4)  PC units purchased in quarter = [Small System units purchased in 
             the quarter] divided by [1.0]

        (5)  Cost of PC's purchased in quarter = [PC units purchased in 
             quarter] multiplied by [$5,000]

        (6)  Square footage required for Infrastructure build-out in quarter 
             = [Small System units purchased in quarter] divided by [8] and 
             then multiplied by [6]

        (7)  Cost of Infrastructure build-out in quarter = [square footage 
             required for Infrastructure build-out in quarter] multiplied by 
             [$350]

    (b) Summary calculations are:

        (1) Capital expenses in the quarter = the sum of [5.a.3], [5.a.5]
            and [5.a.7] above in the same quarter

        (2) Depreciation for the capital expenses incurred in the quarter = 
            [5.b.1] divided by [8].

Not withstanding the foregoing, if less than a full quarter is completed the 
maximum amount due will be prorated accordingly.

Not withstanding the foregoing, changes that may impact these actual 
obligations include but are not limited to: NETSCAPE's assumption of 
activities and operations that are provided by ADFORCE in the current 
estimate, such as headcount, hardware, bandwidth, and facilities; and changes 
to the impression forecast which impact these costs.

Specifically, unless the parties mutually agree otherwise, if NETSCAPE were 
to assume any such activities and operations, NETSCAPE's obligation for the 
subsequent periods would be reduced by a ratable amount in the 
corresponding line item in Exhibit C, after adjusting for changes to Exhibit 
C described above.

Unless the parties mutually agree otherwise, milestones regarding the timing 
and adjustment of payments will be made per Section 9.1 of the Agreement.

                             EXHIBIT D

             MUTUAL CONFIDENTIAL DISCLOSURE AGREEMENT

This Mutual Confidential Disclosure Agreement ("Agreement") is entered into 
between NETSCAPE Communications Corporation ("NETSCAPE") and IMGIS, INC, dba 
ADFORCE ("Company"), and is effective as of the date of execution by NETSCAPE 
("Effective Date"). Each party (the "Receiving Party") understands that the 
other party (the "Disclosing Party") may disclose certain Confidential 
Information (as defined in Section 1 below) under this Agreement. NETSCAPE 
and Company agree as follows:

1.  DEFINITION. "Confidential Information" shall mean (i) all information    
    disclosed in tangible form by the Disclosing Party and marked 
    "confidential" or "proprietary", and (ii) all information disclosed 
    orally or otherwise in intangible form by the Disclosing Party and 
    designated as confidential or proprietary at the time of disclosure. 
    Confidential Information may include, without limitation, computer 
    programs, code, algorithms, names and expertise of employees and 
    consultants, know-how, formulas, processes, ideas, inventions (whether 
    patentable or not), schematics and other technical, business, financial 
    and product development plans, forecasts, strategies and information.

2.  PURPOSE. The Receiving Party shall use the Confidential Information only 
    for the following purposes:

    a)  To evaluate whether to enter into a contemplated business transaction;
    and

    b) if NETSCAPE and Company enter into such contemplated business 
    transaction, to fulfill each party's commitments under the agreement for 
    such business transaction.

3.  CONFIDENTIALITY OBLIGATION. The Receiving Party agrees to protect the 
    Confidential Information by using the same degree of care, but not less 
    than a reasonable degree of care, to prevent the unauthorized use, 
    dissemination or publication of the Confidential Information as the 
    Receiving Party uses to protect its own confidential or proprietary 
    information of a like nature. The Receiving Party shall limit the use of 
    and access to the Disclosing Party's Confidential Information to the 
    Receiving Party's employees or independent contractors who need to know 
    such Confidential Information for the purposes set forth in Section 2 
    above and who have entered into binding obligations of confidentiality 
    substantially similar to the obligations set forth herein.

4.  TERM. The Receiving Party's obligations to protect Confidential 
    Information hereunder shall expire 3 years from the date of each such 
    disclosure of Confidential Information, except when such Confidential 
    Information disclosed by the Disclosing Party is source code, in which 
    case the Receiving Party's obligations to protect such Confidential 
    Information shall be perpetual.

5.  EXCLUSION. Confidential Information as defined in Section 1 above shall 
    not include Confidential Information that: (i) is or becomes a matter of 
    public knowledge through no fault of the Receiving Party; or (ii) was in 
    the Receiving Party's possession or known by it prior to receipt from the 
    Disclosing Party; or (iii) was rightfully disclosed to the Receiving 
    Party by another person without restriction; or (iv) is independently 
    developed by the Receiving Party without access to Disclosing Party's 
    Confidential Information. The Receiving Party may disclose Confidential 
    Information pursuant to any statutory or regulatory authority or court

<PAGE>

                                                                  CONFIDENTIAL

    order, provided the Disclosing Party is given prompt written notice of 
    such requirement and the scope of such disclosure is limited to the 
    extent possible.

6.  INDEPENDENT DEVELOPMENT. The terms of confidentiality under this Agreement 
    shall not be construed to limit either party's right to independently 
    develop or acquire products without use of the other party's Confidential 
    Information. Further, Confidential Information as defined in Section 1 
    above shall not include the Residuals resulting from access to such 
    Confidential Information. The term "Residuals" means information in 
    intangible form which may be retained in the unaided memories of 
    Receiving Party's employees or independent contractors who have had 
    access to the information. An employee's or contractor's memory will be 
    considered to be unaided if the employee has not intentionally memorized 
    the Confidential Information for the purpose of retaining and 
    subsequently using or disclosing it. Neither party shall have any 
    obligation to limit or restrict the assignment of such persons or to pay 
    royalties for any work resulting from the use of Residuals. However, the 
    foregoing shall not be deemed to grant to either party a license under 
    the other party's copyrights or patents.

7.  RETURN OF CONFIDENTIAL INFORMATION. Upon written request by the Disclosing 
    Party at any time, the Receiving Party shall: (i) turn over to the 
    Disclosing Party all Confidential Information of the Disclosing Party, 
    all documents or media containing the Confidential Information, and any 
    and all copies or extracts thereof, or (ii) destroy the Confidential 
    Information, and any and all copies or extracts thereof, and provide the 
    Disclosing Party with written certification of such destruction signed 
    by an authorized representative of the Receiving Party.

8.  EQUITABLE RELIEF. The Receiving Party acknowledges and agrees that due to 
    the unique nature of the Disclosing Party's Confidential Information, 
    there may be no adequate remedy at law for any breach of its obligations. 
    The Receiving Party further acknowledges that any such breach may allow 
    the Receiving Party or third parties to unfairly compete with the 
    Disclosing Party resulting in irreparable harm to the Disclosing Party 
    and, therefore, that upon any such breach or any threat thereof, the 
    Disclosing Party shall be entitled to seek appropriate equitable relief 
    in addition to whatever remedies it may have at law. The Receiving Party 
    will notify the Disclosing Party in writing immediately upon the 
    occurrence of any such unauthorized release or other breach.

9.  INTELLECTUAL PROPERTY RIGHTS. Neither party acquires any intellectual 
    property rights or any other rights under this Agreement or through any 
    disclosure hereunder, except the limited right to use the Confidential 
    Information in accordance with this Agreement.
 
10. WARRANTY. THE CONFIDENTIAL INFORMATION IS DISCLOSED UNDER THIS AGREEMENT 
    IS DELIVERED "AS IS," AND ALL REPRESENTATIONS OR WARRANTIES, WHETHER 
    EXPRESS OR IMPLIED, INCLUDING WARRANTIES OR CONDITIONS FOR FITNESS FOR A 
    PARTICULAR PURPOSE, MERCHANTABILITY, TITLE AND NONINFRINGEMENT, ARE 
    HEREBY DISCLAIMED.

11. NETSCAPE SUBSIDIARIES. NETSCAPE's wholly owned subsidiaries, by signing 
    this Agreement on behalf of NETSCAPE and returning a fully executed 
    original or copy to the NETSCAPE Legal Department, shall be entitled to 
    disclose NETSCAPE's Confidential Information and receive Company's 
    Confidential Information on a need to know basis only on behalf of 
    NETSCAPE under this Agreement, provided such subsidiaries comply with the 
    terms and conditions of this Agreement and further provided such 
    disclosures or receipt of

    No waiver or modification of this Agreement will be binding upon either 
    party unless made in writing and signed by a duly authorized

    requires either party to proceed with any proposed transaction or 
    relationship in connection with which Confidential Information may be 
    disclosed. In the event that any of the provisions of this Agreement 
    shall be held by a court or other tribunal of competent jurisdiction to
